In general, deep groundwater displays higher δ18O ratios than shallow groundwater does (Freeze and Cherry, 1979), since deep groundwater reacts with bedrock which commonly emits more 18O than 16O. However, δ18O ratios in the bedrock groundwater in this area opposed to general trend, indicating not enough time to react with bedrock and diffusion effect probably (Hoefs, 1997).

When an Indonesian LNG tanker arrived in Korea for the first time in October 1986, Korea became the seventh LNG-consuming nation in the world. The imported LNG has contributed greatly to solving pollution problems and ensuring a stable supply of energy to Korea through the diversification of energy sources. So far, the LNG supply has been confined to the Metropolitan area. The Korea Gas Corporation now plans to expand the LNG supply to cover the entire nation. This paper introduces the experience and future plan of Korea's LNG projects with a special reference to their financial structure

Fusion research in Korea is still premature, but it is a fast growing program. Groups in several universities and research institutes were working either in small experiments or in theoretical areas. Recently, couple of institutes who have small fusion-related experiments, proposed medium-size tokamak programs to jump into fusion research at the level of international recognition. Last year, Korean government finally approved to construct 'Superconducting Tokamak' as a national fusion program, and industries such as Korea Electric Power Corp. (KEPCO) and Samsung joined to support this program. Korea Basic Science Institute (KBSI) has organized national project teams including universities, research institutes and companies.

Full Text Available The purpose of this article is to present empirical research to reveal the reality of the New Homiletic in South Korea. This research was conducted by means of semistructured interviews with seven pastors and eight laypeople of the evangelical faith, residing in Seoul and its metropolitan areas, within the age limits of 20�59 years. The aim was to uncover the experience of the sermons by both the preachers and the hearers of the sermons. The researcher chose Pieterse�s methodology of analysing the data, which is an inductive analysis called open coding. Six main categories from the pastor�s group and five categories from the laypeople emerged from the data. The categories were rearranged into four themes, which is a valuable finding for current-day Korean preaching in order to enhance the homiletical praxis.Intradisciplinary and/or interdisciplinary implications: This article presents empirical research on the reality of the New Homiletic in South Korea. The results indicate similarity between South Korea and the USA. The conclusion is that traditional discourse should give way to the New Homiletic. This research can become the basis for finding new strategies for evangelical preaching.Keywods: Preaching; South Korean church; Empirical research; New Homiletic

Forty-year (1971-2010) observations of cloud cover and types have been analyzed, and implications on the effects of aerosol-cloud feedback were explored. Cloud cover and types have been observed over Korea on the basis of visible (human-eye) attributes without any change in official observing instructions. Visibility has been used as an ongoing proxy measure of aerosol concentrations, and observed meteorological variables such as sunshine duration and precipitation have been employed to analyze aerosol causes and implications for urban and regional climate. The analysis revealed persistent decade-long patterns in Korea: steadily reduced visibility (-0.37 km/yr), consistently decreasing sunshine duration (-0.06 %/hr), and declining occurrence of light precipitation. Spatial distributions of sunshine duration and visibility exhibited more localized variations in the early period (1971-1990), and tended to be more uniform throughout Korea over more recent years (1991-2010), implying the recent regional-scale impact of cloud change over northeast Asia. Cloud analysis results showed that the five most common types were stratocumulus (Sc), cirrus (Ci), altostratus (As), stratus (St), and nimbostratus (Ns), with occurrences of 33%, 17%, 17%, 9%, and 8%, respectively. Occurrence of rarely precipitating or nonprecipitating low-level Sc clouds showed an increasing (+0.34%/yr), but no (or only minor) effects of aerosols on heavy precipitation such as cumulus cloud types were found. Cloud cover in the range of 6/10 to 8/10 units has increased by 31.5±6.5%, and occurrences of both cloud-free (~2/10 units) and overcast (~8/10 units) conditions have decreased. Aerosol-cloud-precipitations interaction is highly nonlinear due to feedback mechanisms. One reason for our poor understanding of the aerosol-cloud feedback study is the variety of cloud types with their complicated responses to variations of the aerosol. Our study on the response of precipitation-cloud to long

South Korea aspires to become a major nuclear supplier in the world nuclear market. There is no doubt that South Korea has great potential to fulfill these aspirations. South Korea is well positioned in terms of competitiveness, market relationships, institutional capability, ability to deliver, and commitment to nonproliferation values. As a mercantilist state, South Korea hopes to capitalize on its close relationships with transnational nuclear corporations in this endeavor. It hopes to participate in two- or three-way joint ventures---especially with the American firms that have traditionally predominated in the South Korean domestic nuclear business---to market their nuclear wares abroad. This paper is divided into four parts. The first section describes South Korea's intent to become a nuclear supplier in the 1990s. It delineates the networks of prior transactions and relationships that South Korea may use to penetrate export markets. The second section reviews South Korea's nuclear export potential, particularly its technological acquisitions from the domestic nuclear program. These capabilities will determine the rate at which South Korea can enter specific nuclear markets. The third section describes the institutional framework in South Korea for the review and approval of nuclear exports

Woosaeng, meaning "eugenic" in Korean, was a bulletin published by the Korean Eugenics Association in 1934. With detailed review of the contributors to Woosaeng, its publication background and the contents, the characteristics of Korea's eugenic movement in 1930's and its historical implications of public health are studied. Intellectuals, especially some medical doctors educated abroad, played the pivotal role in publishing Woosaeng and leading the eugenic movement in 1930's. Lee Gabsoo, a medical doctor educated in Germany, is identified as the key person in the whole process. Most of contributors including Lee considered medical science, especially genetics, as the foundation of eugenics and had strong confidence in their belief. A variety of eugenic movements and activities, including enactment of the national eugenic law around the world. was introduced to the Korean society through Woosaeng and it reinforced the eugenic activities in Korea. Although colonial Korea at the time was being heavily imposed with Japan's culture, the eugenic activities were also influenced by Germany and the US through the contributors educated oversea. The overall content and tone of Woosaeng, revealed its 'soft' characteristics, yet it also implied its vulnerability to 'hard' eugenics. Korea's eugenic movement around Woosaeng faces turnover right before 'The Go Fast Imperialism' period. The high class intellectuals tamed by Japanese colonial paradigm in eugenics took the lead and ended up having a significant influence upon the activities around Woosaeng. And even after Koreans' liberation from Japan's annexation, they were able to retain their influence in public health area in the Korean society. In summary, Woosaeng guided us to understand the characteristics of Korea's eugenic movement in 1930's and the historical context of public health in Korea. Moreover, Woosaeng provided a large amount of information about the eugenic movements around the world as well as in Korea. It

The objective of this study was to measure secondhand smoke (SHS) exposure in personal computer (PC) rooms with the purpose of determining the strength of scientific evidence supporting the legislative ban on smoking in PC rooms located in the Republic of Korea. From June to September 2012, particulate matter (PM2.5) and air nicotine concentration (ANC) were measured in the smoking and non-smoking areas of PC rooms in Goyang City, Korea. In 28 randomly sampled PC rooms, field investigators completed an observational questionnaire on building characteristics, smoking policies, and evidence of smoking. The geometric means (GM) of PM2.5 and ANC in smoking and non-smoking areas were compared. Evidence of smoking was identified in both the smoking and non-smoking areas of all PC rooms. The GMs of PM2.5 and ANC in both areas were high and did not differ significantly (174.77 μg/m(3) and 48.95 μg/m(3) in smoking areas; 93.38 μg/m(3) and 41.30 μg/m(3) in non-smoking areas). Overall PM2.5 concentrations were 5.5-fold higher than those listed in the World Health Organization guidelines. This study supported previous reports that a partial smoking ban did not protect individuals from SHS exposure. Furthermore, the results from our study suggest how research can support policy. Countries in which smoke-free policies are not yet comprehensive may find our results useful.

The Moderate Resolution Imaging Radiometer (MODIS) Gross Primary Productivity (GPP)/Net Primary Productivity (NPP) has been widely used for the study on global terrestrial ecosystem and carbon cycle. The current MODIS product with ~ 1 km spatial resolution, however, has limitation on the information on local scale environment (fairly comparable values of the MODIS here however, cannot assure the quality of the MOD17 over the complex vegetation area of Korea since the ground measurements except the eddy covariance tower flux measurements are highly inconsistent. Therefore, the comprehensive experiments to represents GPP/NPP over diverse vegetation types for a comparable scale of MODIS with a consistent measurement technique are necessary in order to evaluate the MODIS vegetation productivity data over Korea, which contains a large portion of highly heterogeneous vegetation area.

KINS has developed and used Safety Performance Indicators (SPIs), which are count based and composed of 10 indicators in 8 areas, to monitor the trend of performance of NPPs in Korea since 1997. However, the limited usage of SPIs and the increasing worldwide interest on SPIs became the motivation of the SPI improvement programme in Korea. Korea is planning to establish plant performance evaluation programme through analysis of SPI and result of inspection. The SPI improvement programme is a part of the plant performance evaluation programme and includes study on performance evaluation areas, indicator categories, selection and development of indicators, redefinition of indicators and introduction of graphical display system. The selected performance evaluation areas are general performance, reactor safety and radiation safety. Each area will have categories as sub-areas and a total of six categories are selected. One or two indicators for each category are determined or will be developed to make a set of Safety Performance Indicators. Also, a graphic display system will be introduced to extend the usage of SPIs. (author)

Fear of Crime in South Korea

Ben Brown

2016-12-01

Full Text Available This study provides analyses of data on crime-associated trepidation obtained from surveys administered to college students in South Korea. The survey contained questions about, and the analyses distinguished between, offense-specific fears (fear of burglary and fear of home invasion, perceived risk of victimization (day and night, and crime avoidance behaviors (avoidance of nocturnal activity and avoidance of particular areas. Regression analyses of the data show that victimization was not consistently associated with crime-associated trepidation, while gender significantly impacted all measures of concern about crime. Women were more likely than men to report being fearful, perceiving risk, and crime avoidance behaviors. Building upon prior scholarship (for example, Madriz 1997; Stanko 1989 and considering the social context in which the data were gathered, it is herein suggested that the gendered variation in crime-associated anxiety may reflect patriarchal power relations. The methodological and policy implications of the study are also discussed.

We explored the relationship between acculturation and dietary intake by gender for 500 Mongolians residing in South Korea. The high acculturation (HA) group females consumed more fish and shellfish, vegetables, beans, and rice, and less meats, flours, and oil than the low acculturation (LA) group did. However, there was no statistical difference in food group intake between HA and LA group males. HA group females showed higher intake of carbohydrates, fiber, sodium, potassium, calcium, vitamin A, and folate compared with LA group females. However, only folate and vitamin B2 intake was statistically different between HA and LA group males. Acculturation and gender interactions were found for the consumption of meats, flours, fish and shellfish, beans, and vegetables. The findings from this study have implications for developing customized nutrition intervention programs by gender for immigrants.

Asian Dust particles originated from the deserts and loess areas of the Asian continent are often transported over Korea, Japan, and the North Pacific Ocean during spring season. Major air mass pathway of Asian dust storm to Korea is from either north-western Chinese desert regions or north-eastern Chinese sandy areas. The local atmospheric environment condition in Korea is greatly impacted by Asian dust particles transported by prevailing westerly wind. Since these Asian dust particles pass through heavily populated urban and industrial areas in China before it reach Korean peninsular, their physical, chemical and optical properties vary depending on the atmospheric conditions and air mass pathway characteristics. An integrated system approach has been adopted at the Advanced Environment Monitoring Research Center (ADEMRC), Gwangju Institute Science and Technology (GIST), Korea for effective monitoring of atmospheric aerosols utilizing various in-situ and optical remote sensing methods, which include a multi-channel Raman LIDAR system, sunphotometer, satellite, and in-situ instruments. Results from recent studies on impacts of Asian dust particles on local air quality and radiative forcing over Korea are summarized here.

Characteristics of newly found Quaternary fault, southern Korea, and its tectonic implication

This study introduces the detailed geometry and kinematics of recently found Quaternary fault in southern Korea, named Seooe Fault, and discusses its tectonic implication through a synthetic analysis with previous studies. The N-S striking Seooe Fault shows a top-to-the-east thrust geometry and cuts the Cretaceous Goseong Formation and overlying Quaternary deposits, and its slip senses and associated minor folds in the hanging wall indicate an E-W compressional stress. The age of the lower part of the Quaternary deposits obtained by OSL dating indicates that the last movement of the fault occurred after 61 60 ka. Arcuate geometry of the main fault showing an upward decreasing dip-angle, reverse offset of the fault breccias, and reverse-sense indicators observed on neighboring N-S striking high-angle fractures indicate that this Quaternary fault was produced by the reactivation of pre-existing fault under E-W compressional stress field. Using the apparent vertical displacement of the fault and the attitudes of cutting slope and main fault surface, its minimum net displacement is calculated as 2.17 m. When the value is applied to the empirical equation of maximum displacement - moment earthquake magnitude (Mw), the magnitude is estimated to reach about 6.7, assuming that this displacement was due to one seismic event. Most of the Quaternary faults in southern Korea are observed along major inherited fault zones, and their geometry and kinematics indicate that they were reactivated under ENE-WSW or E-W compressional stress field, which is concordant with the characteristics of the Seooe Fault. In addition, focal mechanism solutions and geotechnical in-situ stress data in and around the Korean peninsula also support the current ENE-WSW or E-W regional compression. On the basis of the regional stress trajectories in and around East Asia, the current stress field in Korean peninsula is interpreted to have resulted from the cooperation of westward shallow subduction of

Bank filtrated water has been used in developed countries such as United States, France, Germany, Austria, Nederland and so on. In Korea, most of the drinking water is provided from the surface water. However, drinking water acquisition is becoming difficult due to the degradation of surface water quality. In special, the quality of drinking water source is much lower in downstream area than in upstream area. Thus, the use of bank filtrated water is getting attracted by central and local governments in Korea. The bank filtrated water was surveyed in the areas of Yeongsan river, Nakdong river, Geum river and Han river. Up to present, however, the downstream areas of Nakdong river are most suitable places to apply the bank filtration system. This study investigates hydrogeological characteristics of bank-storage area located in Daesan- Myeon, Changwon city, adjacent the downstream of Nakdong river. Changwon city is the capital city of Gyeongsangnam-Do province. Changwon city uses water derived from Nakdong river as municipal water. However, the quantity and quality of the river water are gradually decreased. Thus, Changwon city developed two sites of bank filtration system in Daesan-myeon and Buk-myeon. Pumping rate is 2,000m3/day at present and will be increased to 60,000m3/day in Daesan-myeon site at the end of the first stage of the project. For the study, we conducted pumping tests four times on seven pumping wells (PW1, PW2, PW3, PW4, PW5, PW6, and PW7) and twelve drill holes (BH-2, OW2-OW12) in the area of 370 m x 100 m. Pumping wells PW1 and PW2 were drilled in 1999 by Samjung Engineering Co. and pumping wells PW3, PW4, PW5, PW6 and PW7 were drilled in 2000 by Donga Construction Co. and Daeduk Gongyeong Co. The pumping wells are located at 45-110 meters from Nakdong riverside. The geology of the study area is composed of volcanic rocks (Palryeongsan tuff and Jusasan andesitic rock) and alluvium. Palryeongsan tuff consists of mostly green tuff with partly

Full Text Available This study aims to provide an opinion on the state-of-the-art of changes and reforms of water policies in South Korea, as well as the challenges along with their implications for sustainable water governance and management. In parallel with change in water resource characteristics generated by physical, environmental and socio-economic challenges such as: (1 uncertainties about climate change (flooding and drought including seasonal and regional variation in precipitation; (2 significant increase in water use caused by rapid urbanization and population growth in industrialized urban areas; (3 inadequate water pricing mechanism which covers only around 80% of the production cost and makes it harder to maintain water systems; and (4 recursive water quality degradation and conflicts over water rights between regions resulting from non-point source pollution in highland versus lowland areas, Korean water policies have been developed through diverse reforms over 100 years. Nevertheless, new challenges for sustainable water management are continuously emerging. To meet those challenges we provide two ideas: (i provider-gets-principle (payment for ecosystem services of cost-benefit sharing among stakeholders who benefit from water use; and (ii water pricing applying full-cost pricing-principle internalizing environmental externalities caused by the intensive water use. Funds secured from the application of those methods would facilitate: (1 support for upstream (rural low income householders suffering from economic restrictions; (2 improvement in water facilities; and (3 efficient water use and demand management in South Korea’s water sectors. We expect that this paper can examine the lessons relevant to challenges that South Korea faces and offer some implications on the formulation of new integration and further reforms of the institutions, laws and organizations responsible for managing water resources in South Korea.

No other country in the world has so few resources of fossil sources of energy and depends on imports of power as the Republic of Korea. As a consequence of economical and political processes of globalization, new challenges are developed: elevated regional and global conflicts relating to resources as well as new possibilities of cooperation by means of amore intensely international division of labour. Under this aspect, the author of the contribution under consideration reports on the energy policy of the Republic of Korea. Especially, the author reports on the following aspects: (a) Characteristics of the power structure of the Republic of Korea; (b) National energy policy and measures for energy security; (c) Practical measures of energy security; (d) Regional co-operation for energy security from the view of the Republic of Korea. The Republic of Korea has a very weak energy structure and strongly depends on foreign countries. Among the successful measures of energy security, there exist measures for energy saving in industrial areas, diversification of sources of energy and exporting countries, increase of competitiveness of the energy economy due to restructuring and privatization of national companies as well as liberalisation of the energy market. Investments in the research of energy saving technologies and renewable energy such as solar energy, hydraulic power and fuel cells are trend-setting. The development of new sources of energy and the increase of the self-fund relating to petroleum, coal and natural gas are encouraging. The Republic of Korea is not attached at the international power net. Therefore, the Republic of Korea highly is susceptible according to energy crisis. The elevated dependence from other countries will exist furthermore. The Republic of Korea should expend its activities relating to foreign affairs and the large oil producers

Full Text Available The purpose of this study is to examine the historical factors which affected the rise of modern higher education during the late Choson period (1880-1910, and to analyze the implications of these historical factors on educational policies in contemporary higher education in Korea. The rise of modern higher education in Korea can be viewed as occurring in three principal phases: Confucian Choson Royal Government, Western Christian missionaries, and patriotic nationalists. The author points out that the major historical factors influencing the development of modern higher education were Confucianism, Christianity, and Korean nationalism. In particular, Confucianism and Christianity have had substantial impacts on the planning of educational policies in contemporary Korean higher education; the former is viewed as an original source of educational enthusiasm which has expanded Korean higher education, and the latter a matrix of modern Korean higher education which has embodied educational enthusiasm.

We have reported a high prevalence of breast cancer in light-polluted areas in Korea. However, it is necessary to analyze the spatial effects of light polluted areas on breast cancer because light pollution levels are correlated with region proximity to central urbanized areas in studied cities. In this study, we applied a spatial regression method (an intrinsic conditional autoregressive [iCAR] model) to analyze the relationship between the incidence of breast cancer and artificial light at night (ALAN) levels in 25 regions including central city, urbanized, and rural areas. By Poisson regression analysis, there was a significant correlation between ALAN, alcohol consumption rates, and the incidence of breast cancer. We also found significant spatial effects between ALAN and the incidence of breast cancer, with an increase in the deviance information criterion (DIC) from 374.3 to 348.6 and an increase in R2 from 0.574 to 0.667. Therefore, spatial analysis (an iCAR model) is more appropriate for assessing ALAN effects on breast cancer. To our knowledge, this study is the first to show spatial effects of light pollution on breast cancer, despite the limitations of an ecological study. We suggest that a decrease in ALAN could reduce breast cancer more than expected because of spatial effects.

Korea's Horizontal and Vertical Intra-Industry Trade and FDI in Trade with East Asian Countries

Full Text Available This paper examines Korea's intra-industry trade (IIT by disentangling vertical from horizontal IIT, and analyzes the determinants of both IIT types in trade with East Asian countries during the period of 1991-2005. Korea's IIT with East Asian countries has increased rapidly, especially its high quality IIT, which has increased faster than horizontal IIT and low quality IIT, implying that Korea's product quality has improved over time. Korea's high quality IIT is larger in trade with developing countries, but its low quality IIT is larger in trade with Japan. The regression results show that the income differences between countries have a negative effect on horizontal IIT, and that Korea's high quality IIT becomes larger when Korea's income is higher than the income of partner countries. This supports the theory of IIT. Foreign direct investment (FDI inflow has had a positive effect on increases in IIT, but the effects of FDI outflow are not certain. This suggests a policy implication that FDI inflow has a more positive effect on IIT than FDI outflow.

The importance of climate change has been increasingly recognized because it has had the huge amount of impact on social, economic, and environmental aspect. For the reason, paleoclimate change has been studied intensively using different geological tools including borehole temperatures and future surface air temperatures (SATs) have been predicted for the local areas and the globe. Future subsurface temperatures can have also enormous impact on various areas and be predicted by an analytical method or a numerical simulation using measured and predicted SATs, and thermal diffusivity data of rocks. SATs have been measured at 73 meteorological observatories since 1907 in Korea and predicted at same locations up to the year of 2100. Measured SATs at the Seoul meteorological observatory increased by about 3.0 K from the year of 1907 to the present. Predicted SATs have 4 different scenarios depending on mainly CO2 concentration and national action plan on climate change in the future. The hottest scenario shows that SATs in Korea will increase by about 5.0 K from the present to the year of 2100. In addition, thermal diffusivity values have been measured on 2,903 rock samples collected from entire Korea. Data pretreatment based on autocorrelation analysis was conducted to control high frequency noise in thermal diffusivity data. Finally, future subsurface temperatures in Korea were predicted up to the year of 2100 by a FEM simulation code (COMSOL Multiphysics) using measured and predicted SATs, and thermal diffusivity data in Korea. At Seoul, the results of predictions show that subsurface temperatures will increase by about 5.4 K, 3.0 K, 1.5 K, and 0.2 K from the present to 2050 and then by about 7.9 K, 4.8 K, 2.5 K, and 0.5 K to 2100 at the depths of 10 m, 50 m, 100 m, and 200 m, respectively. We are now proceeding numerical simulations for subsurface temperature predictions for 73 locations in Korea.

Social services as defined here are relatively new phenomena unlike areas such as education or health care. Establishing social care services for citizens on a collective basis is hence an indica-tion of a mature or developed society. Both Korea and Denmark have opted for a universal approach...... to service delivery, but while the traditional Scandinavian scheme emphasizes service delivery as a right irrespective of household situation and income and wealth, Korea has chosen a means tested system.

Green Roof for Stormwater Management in a Highly Urbanized Area: The Case of Seoul, Korea

Directory of Open Access Journals (Sweden)

Muhammad Shafique

2018-02-01

Full Text Available Urbanization changes natural pervious surfaces to hard, impervious surfaces such as roads, buildings and roofs. These modifications significantly affect the natural hydrologic cycle by increasing stormwater runoff rates and volume. Under these circumstances, green roofs offer multiple benefits including on-site stormwater management that mimics the natural hydrologic conditions in an urban area. It can retain a large amount of rainwater for a longer time and delay the peak discharge. However, there is very limited research that has been carried out on the retrofitted green roof for stormwater management for South Korean conditions. This study has investigated the performance of retrofitted green roofs for stormwater management in a highly urbanized area of Seoul, the capital city of Korea. In this study, various storm events were monitored and the research results were analyzed to check the performance of the green roof with controlling the runoff in urban areas. Results also allowed us to conclude that the retention mainly depends on the intensity and duration of the rain events. From the analysis, average runoff retention on the green roof was 10% to 60% in different rain events. The application of an extensive green roof provides promising results for stormwater management in the highly urbanized area of Seoul.

Im, Eun-Ok

2003-10-01

This article reports on cultural influences on symptoms experienced during menopausal transition of Korean women in South Korea and Korean immigrant women in the United States. Data from independent studies of two groups of Korean women were triangulated and analyzed using descriptive and inferential statistics. The analysis indicated that Korean women in South Korea tended to report more symptoms than Korean immigrant women in the United States. Types and severity of prevalent symptoms were also found to be different between the two groups. The findings suggest that recent introduction of menopausal industries in South Korea and contextual influences on Korean women's work and immigration in the United States would be the reason for differences. Based on the findings, implications for future research are proposed.

Drinking water is a main source of human exposure to arsenic. Hence, the determination of arsenic in groundwater is essential to assess its impact on public health. Here, we report arsenic levels in the groundwater of 722 sites covering all six major provinces of Korea. Water was sampled in two occasions (summer, 722 sites and winter, 636 sites) and the arsenic levels were measured with highly sensitive inductively coupled plasma-mass spectrometry method (limit of detection, 0.1 μg/l) to encompass the current drinking water standard (arsenic in groundwater ranged from 0.1 to 48.4 μg/l. A 88.0-89.0% of sites were 10 μg/l. Notably, urinary arsenic excretion of people around these regions was markedly higher compared with non-contaminated areas (arsenic-contaminated groundwater may contribute to its systemic exposure.

2017-12-01

Assessing suitable areas for crops would be useful to design alternate cropping systems as an adaptation option to climate change adaptation. Although suitable areas could be identified by using a crop growth model, it would require a number of input parameters including cultivar and soil. Instead, a simple climate suitability model, e.g., EcoCrop model, could be used for an assessment of climate suitability for a major grain crop. The objective of this study was to assess of climate suitability for maize using the EcoCrop model under climate change conditions in Korea. A long term climate data from 2000 - 2100 were compiled from weather data source. The EcoCrop model implemented in R was used to determine climate suitability index at each grid cell. Overall, the EcoCrop model tended to identify suitable areas for maize production near the coastal areas whereas the actual major production areas located in inland areas. It is likely that the discrepancy between assessed and actual crop production areas would result from the socioeconomic aspects of maize production. Because the price of maize is considerably low, maize has been grown in an area where moisture and temperature conditions would be less than optimum. In part, a simple algorithm to predict climate suitability for maize would caused a relatively large error in climate suitability assessment under the present climate conditions. In 2050s, the climate suitability for maize increased in a large areas in southern and western part of Korea. In particular, the plain areas near the coastal region had considerably greater suitability index in the future compared with mountainous areas. The expansion of suitable areas for maize would help crop production policy making such as the allocation of rice production area for other crops due to considerably less demand for the rice in Korea.

An Analysis of Infectious Disease Research Trends in Medical Journals From North Korea

Do-Hyeon Park

2018-03-01

Full Text Available Objectives This study aimed to investigate the current status of infectious disease research in North Korea by analyzing recent trends in medical journals from North Korea in comparison with research from South Korea. Methods Three medical journals (Preventive Medicine, Basic Medicine, and Chosun Medicine were analyzed from 2012 to 2016. Articles on tuberculosis (TB, malaria, and parasitic diseases were selected and classified by their subtopics and study areas. Two medical journals published in the South Korea were selected for a comparative analysis of research trends. Results Of the 2792 articles that were reviewed, 93 were extracted from North Korea journals. TB research in North Korea was largely focused on multi-drug resistant TB and extrapulmonary TB, whereas research in South Korea more frequently investigated non-tuberculous mycobacteria. Research on parasitic diseases in North Korea was focused on protozoan and intestinal nematodes, while the corresponding South Korea research investigated various species of parasites. Additionally, the studies conducted in North Korea were more likely to investigate the application of traditional medicine to diagnosis and treatment than those conducted in South Korea. Conclusions This study presents an analysis of research trends in preventive medicine in North Korea focusing on infectious diseases, in which clear differences were observed between South and North Korea. Trends in research topics suggest a high prevalence of certain parasitic diseases in North Korea that are no longer widespread in South Korea. The large proportion of studies examining traditional medicine implies a lack of affordable medicine in North Korea.

Cancer control and the communication innovation in South Korea: implications for cancer disparities.

Science.gov (United States)

Jung, Minsoo

2013-01-01

Over the last 10 years, the number of cancer survivors in South Korea has reached nearly one million with a survival rate of 49.4%. However, integrated supportive care for cancer survivors is lagging. One area in which the current cancer control policy needs updating is in the utilization of information and communication technology (ICT). The remarkable progress in the field of ICT over the past 10 years presents exciting new opportunities for health promotion. Recent communication innovations are conducive to the exchange of meta-information, giving rise to a new service area and transforming patients into active medical consumers. Consequently, such innovations encourage active participation in the mutual utilization and sharing of high-quality information. However, these benefits from new ICTs will almost certainly not be equally available to all, leading to so-called communication inequalities where cancer survivors from lower socioeconomic classes will likely have more limited access to the best means of making use of the health information. Therefore, most essentially, emphasis must be placed on helping cancer survivors and their caregivers utilize such advances in ICT to create a more efficient flow of health information, thereby reducing communication inequalities and expanding social support. Once we enhance access to health information and better manage the quality of information, as a matter of fact, we can expect an alleviation of the health inequalities faced by cancer survivors.

Contacts between the South Korean nuclear industry and a combined United Kingdom mission representing AEA Technology and British Nuclear Fuels Limited (BNFL) are reported. Prospects for entering the Korean market in two areas are perceived. The first is waste management and the second is the Safe Integral Reactor (SIR), an advanced pressurized water reactor design. AEA Technology and three collaborators have been promoting SIR as an inherently safe reactor design. Korean interest could be expressed in financial backing for the building of SIR stations in Korea and the opportunity could arise for BNFL to win fuel supply contracts. (UK)

Effects of Temporal and Interspecific Variation of Specific Leaf Area on Leaf Area Index Estimation of Temperate Broadleaved Forests in Korea

Full Text Available This study investigated the effects of interspecific and temporal variation of specific leaf area (SLA, cm2·g−1 on leaf area index (LAI estimation for three deciduous broadleaved forests (Gwangneung (GN, Taehwa (TH, and Gariwang (GRW in Korea with varying ages and composition of tree species. In fall of 2014, fallen leaves were periodically collected using litter traps and classified by species. LAI was estimated by obtaining SLAs using four calculation methods (A: including both interspecific and temporal variation in SLA; B: species specific mean SLA; C: period-specific mean SLA; and D: overall mean, then multiplying the SLAs by the amount of leaves. SLA varied across different species in all plots, and SLAs of upper canopy species were less than those of lower canopy species. The LAIs calculated using method A, the reference method, were GN 6.09, TH 5.42, and GRW 4.33. LAIs calculated using method B showed a difference of up to 3% from the LAI of method A, but LAIs calculated using methods C and D were overestimated. Therefore, species specific SLA must be considered for precise LAI estimation for broadleaved forests that include multiple species.

Kim, Kyoung Mi; Kim, Miyoung

2013-06-01

The study was done to explore meanings and essence of the experience in South Korea of men defectors from North Korea. Data were collected from March, 2011 to May, 2012, through in-depth interviews with ten men defectors. Data analysis was conducted using the process of hermeneutic phenomenological reflection. Eight essential themes were extracted; 'buoyant expectation for a new life', 'feeling guilty about family left behind in North Korea', 'inability to become acclimatized due to communication difficulties', 'inability to socialize with South Koreans due to different lifestyles', 'finding strength through trustworthy acquaintances', 'continuing reconciliation with oneself while trying to assimilate into South Korean culture', 'self-realization of one's original self', and 'continuing to feel out the possibility of a future in South Korea'. The findings indicate that North Korean men who defect to South Korea shape their identity through three phases: forming self-image during escape from North Korea, trying to become accustomed to South Korean society, and finding their own identity by self-realization of their original self. Eventually, the whole process enables them to recover their identity, to feel a sense of belonging, and to discover possibilities for a better future.

In 1985, the population of the Democratic People's Republic of Korea (North Korea) stood at 20 million, with an annual growth rate of 2.3%. The infant mortality rate was 30/1000 live births and life expectancy was 66 years. The gross national product (GNP) was US$23 billion in 1984, with a per capita GNP of $1175. Both North Korea's labor force and natural resources have been concentrated in recent years on an effort to achieve rapid economic development. During the early 1970s, a large-scale modernization program involving the importation of Western technology, primarily in the heavy industiral sectors of the economy, was attempted and resulted in a massive foreign debt. North Korea has a strongly centralized government under the control of the communist Korean Workers' Party. Literacy in the country is at the 99% level. Medical treatment is free. There is 1 physician/600 population and 1 hospital bed/350 inhabitants.

The Northern Sea Routes and Korea's Trade with Europe: Implications for Korea's Shipping Industry

Directory of Open Access Journals (Sweden)

Yeong-Seok Ha

2014-12-01

Full Text Available Melting Arctic waters have brought about global opportunities and challenges. One distinctive opportunity presented by the increasingly ice-free Arctic Ocean is its availability for shipping cargos between Europe and Asia. In adopting highly simplified assumptions of the Northern Sea Route (NSR being navigable and economical enough for shipping and NSR completely substituting for the incumbent Suez Canal route, this paper analyzes the maximum number of voyages possible for the transshipment of container cargo throughput for Korea's trade with Europe, particularly with Europe-17 and Europe-7. Our analysis shows the number of voyages range from over 2,900 to as little as 237 for Europe-17, depending on vessel sizes, when NSR is available for the whole year. With NSR opening for three months, the corresponding figures vary between 727 and 60 for Europe-17, and the figures for Europe-7 are between 2,725 and 222 and 682 and 56 voyages, respectively.

A simple inversion of induced-polarization data collected in the Haenam area of Korea

International Nuclear Information System (INIS)

Jang, Hannuree; Park, Samgyu; Kim, Hee Joon

2014-01-01

We develop a two-stage method to invert induced polarization (IP) data. First, DC resistivity data are inverted to recover a background resistivity that is used to generate a sensitivity matrix for the IP inversion. The second stage accepts the background resistivity as the true resistivity of the medium and attempts to find a polarizability that satisfies the IP data. This is done by linearizing the equations for the background resistivity to produce a linear inverse problem that can be solved for the distribution of the subsurface polarizability. Smoothness and base-model constraints are used to stabilize the IP inversion process. These regularization methods are validated by inverting both synthetic and field data obtained in the Haenam epithermal mineralized area, Korea. As a result, the IP anomaly recovered from the base-model constraint indicates that fine-grained pyrite is disseminated in a shallow zone beneath the ridge of this site, which is confirmed by core samples.

Deforestation change detection in North Korea between 1999 and 2008 using multi temporal satellite image

KIM, K. M.

2017-12-01

After the mid-1990s, North Korea has gone through a hard time of shortage of food and fuel due to the large scale flood and landslide. This became a vicious circle, which has kept accelerating the deforestation in North Korea. This study aims to analyze the change of deforestation in North Korea using two different seasonal satellite images of Landsat 5-TM and SPOT-5 between 1999 and 2008. The Land cover was classified into 6 categories: forest, cropland, grassland, bare land, built area and water body. And the deforested and degraded forest area was extracted considering forest land boundary and classified into 3 categories: the cultivated, the unstocked forest land and the bare mountain. For the all classification process, unsupervised classification method was used since North Korea is inaccessible area. The results of the study showed that the stocked forest area has decreased 1,379,000 ha compared with those in 1999, whereas the deforested and degraded forest area has increased 1,207,000 ha in 2008. The increase of 880,000 ha in the unstocked forest land was the biggest expansion among 3 categories of the deforested and degraded forest area during 9 yrs. It is resulted from an increase of firewood usage, which is presumably owing to the severe shortage of fuel and food. I look forward for the outcome of this study to being used as baseline data for inter-Korean forest cooperation. Especially, it is expected to serve as important input data for the potential REDD project site selection with results of the 3rd forest monitoring(2018) of North Korea.

An Assessment of Forest Cover Trends in South and North Korea, From 1980 to 2010

Engler, Robin; Teplyakov, Victor; Adams, Jonathan M.

2014-01-01

It is generally believed that forest cover in North Korea has undergone a substantial decrease since 1980, while in South Korea, forest cover has remained relatively static during that same period of time. The United Nations Food and Agriculture Organization (FAO) Forest Resources Assessments—based on the reported forest inventories from North and South Korea—suggest a major forest cover decrease in North Korea, but only a slight decrease in South Korea during the last 30 years. In this study, we seek to check and validate those assessments by comparing them to independently derived forest cover maps compiled for three time intervals between 1990 and 2010, as well as to provide a spatially explicit view of forest cover change in the Korean Peninsula since the 1990s. We extracted tree cover data for the Korean Peninsula from existing global datasets derived from satellite imagery. Our estimates, while qualitatively supporting the FAO results, show that North Korea has lost a large number of densely forested areas, and thus in this sense has suffered heavier forest loss than the FAO assessment suggests. Given the limited time interval studied in our assessment, the overall forest loss from North Korea during the whole span of time since 1980 may have been even heavier than in our estimate. For South Korea, our results indicate that the forest cover has remained relatively stable at the national level, but that important variability in forest cover evolution exists at the regional level: While the northern and western provinces show an overall decrease in forested areas, large areas in the southeastern part of the country have increased their forest cover.

The investment expenditures of core infrastructure projects in North Korea are calibrated as 9.35 billion US$ including highway, railroad and industrial complex. Since South and North Koreas are based on market and planned economies respectively, the Computable General Equilibrium model is applied to the economic analysis of South Korea and an Input-Output Model for th...

Preliminary study on the assessment of natural analogue study in Korea for the deep geological disposal of high-level radioactive waste was carried out. The project on natural analogue study in other countries are introduced. The uranium-bearing deposit in Okcheon belt are summarized, which reported to be uranium-bearing minerals in order to assess to feasibility for natural analogue study in Korea. Among the uranium-bearing deposits, the Deokpyeong area, reported to be the highest reservoir and grade, are selected as the study site, and the elementary investigation, including survey of radioactivity and geochemistry are carried out. According to the investigation of surface environment, the radioactivity and uranium content in the surface water and shallow groundwater does not show any anormal values. However, the radioactivity is expected to be increased in depth and the groundwater reacted with uranium-bearing graphite formation shows high unanium content, indicating the potential possibility for natural analogue study in Korea. In future, if more detail study are performed, the assessment of natural analogue study in Korea are expected.

Korea announced standby power of all electronics shall be reduced to below 1W by 2010. Ministry of Knowledge Economy (MKE, Korean government) and Korea Energy Management Corporation (KEMCO) established ''Standby Korea 2010'' which is a roadmap to limit standby power below 1W by 2010. Korea implemented mandatory program over a relatively short period of time, incorporating the better elements from the more established national program and adding new initiatives, such as the threat of using mandatory warning label for products that fail to meet standby power targets.

Korea has the highest suicide rate amongst the OECD countries. Yet, its research on suicidal behaviors has been primitive. While the Interpersonal Psychological Theory of Suicide has gained global attention, there has only been a few researches, which examined its applicability in Korea. In this article, we review the previous studies on suicide and examine the association between the Interpersonal Psychological Theory of Suicide and traditional Korean culture, with an emphasis on Collectivism and Confucianism. We propose that pathways to suicide might vary depending on cultural influences. Clinical implications and suggestions for future research will be discussed.

The master plan of permanent nuclear waste repository had been published in South Korea. The high-level nuclear waste repository should be available in 2053. In this study, six possible nuclear waste forms are simulated by Helium ions. The geological repository is comparative easy and cheap considering the international nuclear act of the nuclear nonproliferation treaty (NPT). How ever, there could be some new technologies of the nuclear waste treatment like the pyroprocessing. Transmutation is another option, which is very expensive with current technology.

1990-01-01

March 1990 marked a major milestone for South Korea's nuclear power program, as the country became self-sufficient in nuclear fuel fabrication. The reconversion line (UF 6 to UO 2 ) came into full operation at the Korea Nuclear Fuel Company's fabrication plant, as the last step in South Korea's program, initiated in the mid-1970s, to localize fuel fabrication. Thus, South Korea now has the capability to produce both CANDU and pressurized water reactor (PWR) fuel assemblies. This article covers the nuclear fuel industry in South Korea-how it is structures, its current capabilities, and its outlook for the future

The mining areas have to face urban decline problem in population and aging after its closing. Many mines were shut down due to changes in industrial structure through 20 century. Central and local governments has been trying to solve urban decline of abandoned mine areas by enacting special acts or introducing support programs for decades. In the year of 1995, South Korean government also enacted "Special act on the assistance to the development of abandoned mine areas" to promote the economy of abandoned mine areas that is depressed following the decline of the coal industry and to help balanced regional development and to improve the living standard of the residents in such abandoned mine areas. Local authorities has been trying to revitalize the regional economy by attracting tourism industry under the financial support and deregulation by this special law. With this background, this study analysis 13 regeneration cases which are utilizing the industrial heritage of the abandoned area in S. Korea. Despite the importance of mining, negative images of abandon mine have been engraved due to environmental destruction. Most of abandoned mines were left without any action since its closing. Early stage of abandoned mine area regeneration, such as Sabuk, Munkyong, are focusing on adjacent land not on abandoned mine. Abandoned mines were restored its original state and theme park including hotels, casinos and other tourist facilities were developed on adjacent land. Eco-trails on some granite caves such as Jungsun were opened to the public as natural resources not industrial heritage. The industrial heritage was very restricted to making museums about history of mining industry. However, there has been a significant change in perception toward reusing industrial heritage for urban regeneration in recent years. From the viewpoint of urban regeneration, abandon mine areas and its facilities are receiving attention as important regional assets as industrial heritage to

Nha, Il-Seong; L. Nha, Sarah; Orchiston, Wayne

There are two books and one review paper that have been written about the history of astronomy in Korea. Chronologically, they are the review paper "Astronomy in Korea" (Rufus, Transactions of the Korea Branch of the Royal Asiatic Society, XXVI, 1-69, 1936), and the books The Hall of Heavenly Records, Korean Astronomical Instruments and Clocks 1380-1780 (Needham et al., Cambridge University Press, Cambridge, 1986a) and History of Astronomy in Korea (Nha, Seoul National University Press, Seoul, 2000). In order to overview the emergence and development of modern astronomy and astrophysics in South Korea, much of the present chapter is based on these three references, along with various papers published by the present authors and other astronomers.

Full Text Available The objective of this study is to derive implications required for efficiency improvement and management level enhancement by selecting container terminals within major large ports of Korea and China as comparison units, evaluating their relative efficiencies and analyzing the trend of changes in their efficiencies. Since the scope of comparison subjects has been narrowed down to container terminals unlike previous studies, it is expected that the study results would have significant meaning due to the fact that it would be possible to compare and analyze in more detail. To achieve the objective, 30 major container terminals in both countries are selected, input and output variables are defined for each terminal and the DEA (data envelopment analysis model is used to conduct an analysis. The results show that the efficiency of major terminals in Korea (CCR: 0.815, BCC: 0.886 showed similar efficiency with China's terminals (CCR: 0.817, BCC: 0.887. While previous studies conclude that the efficiency of ports in Korea is far lower than that of ports in China.

Energy policy of North Korea

Since the year 1990, North Korea suffers internal-policy problems as well as foreign-political problems. The gross domestic investment decreased by 3.8% yearly between the years 1990 and 1998. Many actual problems of North Korea correspond with the energy crisis in this land affecting nearly all sectors of economy and society. This energy crisis was released by the fact, that the former Soviet Union has stopped the supply of primary energy in the year 1991. In the contribution under consideration, the author reports on the energy policy of North Korea. The main themes of this contribution are: (a) Development and characteristics of the energy sector; (b) Crisis of the energy sector; (c) Consequences of the energy crisis in North Korea; (d) Possibilities of the solution of the energy crisis. For the U.S.A. and the international community, the energy crisis offers the possibility to turn North Korea to negotiations by means of remedial measures in the energy sector. In response, North Korea should drop its nuclear energy program. Apart from such positive incentives, the threat of sanctions is conceivable. North Korea imports nearly 70 % of its oil demand from the People's Republic of China. Therefore, China has an great influence on North Korea. The energy crisis of North Korea shows the fatal consequences of a falsely performed energy policy with respect to the population of this land and with respect to the stability and disposing capacity of the political leadership

This study examined the relationships among social media use for information, self-status seeking and socializing, body image, self-esteem, and psychological well-being, and some cultural effects moderating these relationships. Americans (n = 502) and Koreans (n = 518) completed an online survey. The main findings showed that (a) social media use for information about body image is negatively related to body satisfaction in the United States and Korea, while social media use for self-status seeking regarding body image is positively related to body satisfaction only in Korea; and (b) body satisfaction has direct and indirect positive effects on psychological well-being manifested in similar ways in the United States and Korea. Implications and future research directions are discussed.

Terrorism in South Korea.

South Korea has experienced > 30 suspected terrorism-related events since 1958, including attacks against South Korean citizens in foreign countries. The most common types of terrorism used have included bombings, shootings, hijackings, and kidnappings. Prior to 1990, North Korea was responsible for almost all terrorism-related events inside of South Korea, including multiple assassination attempts on its presidents, regular kidnappings of South Korean fisherman, and several high-profile bombings. Since 1990, most of the terrorist attacks against South Korean citizens have occurred abroad and have been related to the emerging worldwide pattern of terrorism by international terrorist organizations or deranged individuals. The 1988 Seoul Olympic Games provided a major stimulus for South Korea to develop a national emergency response system for terrorism-related events based on the participation of multiple ministries. The 11 September 2001 World Trade Center and Pentagon attacks and the 2001 United States of America (US) anthrax letter attacks prompted South Korea to organize a new national system of emergency response for terrorism-related events. The system is based on five divisions for the response to specific types of terrorist events, involving conventional terrorism, bioterrorism, chemical terrorism, radiological terrorism, and cyber-terrorism. No terrorism-related events occurred during the 2002 World Cup and Asian Games held in South Korea. The emergency management of terrorism-related events in South Korea is adapting to the changing risk of terrorism in the new century.

A framework for verifying the dismantlement and abandonment of nuclear weapons. A policy implication for the denuclearization of Korea Peninsula

2011-01-01

Denuclearization of Korean Peninsula has been a serious security issue in the North East Asian region. Although the Six-Party Talks has been suspended since North Korea declared a boycott in 2008, aims of denuclearizing North Korea has still been discussed. For instance, the recent Japan and the U.S. '2+2' dialogue affirmed its importance to achieve complete and verifiable denuclearization of North Korea, including scrutinizing its uranium enrichment program, through irreversible steps under the Six Party process. In order to identify effective and efficient framework for denuclearization of North Korea, this paper examines 5 major denuclearization methods including (1) the Nunn-Luger Method, (2) the Iraqi Method, (3) the South African Method, (4) the Libyan Method and (5) the denuclearization method shown in the Nuclear Weapons Convention (NWC), while referring to the recent developments of the verification studies for nuclear disarmament, such as a joint research conducted by the United Kingdom and Norway and any other arguments made by disarmament experts. Moreover, this paper argues what political and security conditions will be required to make North Korea to accept intrusive verification for its denuclearization. Conditions for successful denuclearization talks among the Six-Party member states and a realistic approach of verifiable denuclearization will be also examined. (author)

South Korea's official development assistance (ODA) has been increasing rapidly and will continue to do so. Korea is one of the few countries which have successfully transitioned from a recipient to a donor. It became a member of DAC (development assistance committee), OECD in November 2009. Korea......'s ODA policy, along with its growth in quantity, is at a crossroads for the enhancement of its quality. Discussions and debates are going on regarding the reforms in Korea's ODA activities, and this paper examines key issues raised. It first reviews the past and present of Korea's ODA, and identifies...... like the objective of ODA, positioning of Korea's ODA as an emerging donor and the nature of aid to North Korea. We also argue that a shift of ODA policy is required to promote reform, based on a thorough reflection on the role of ODA in the alleviation of poverty and promoting sustainable development...

The purpose of this study was to explore American student perceptions of caring for Korean patients during a 2 week exchange program. Perceptions of Korea/Koreans focused on five areas: respect, hospitality and gift giving, ability to speak English, hierarchical relationships, and being protective. Their perceptions of personal change focused in four areas: valuing personal cultural experiences, increasing cultural awareness and compassion, seeing people from other ethnic groups as individuals and developing interest in oriental medicine. Four areas of importance identified when caring for Korean patients included showing respect, importance of family, food, and care for post-partum mothers. Differences were experienced between an individualistic, low-context society (United States) and a collectivist, high context society (Korea) where the influence of Confucianism is pervasive.

Asian-lineage H5 highly pathogenic avian influenza viruses (HPAIV) have caused recurrent outbreaks in poultry and wild birds. In January 2014, H5N8 HPAIV caused outbreaks in South Korea and subsequently spread to East Asia, Europe, and North America. We report the isolation of an H5N8 HPAIV strain from wild birds in Seoul, the most-developed city in South Korea. We analyzed the complete genome sequence of this isolate and estimated its origin using a phylogenetic analysis. The Seoul H5N8 isolate clustered phylogenetically with strains isolated from migratory wild birds but was distinct from Korean poultry isolates. This H5N8 virus was likely introduced into the urbanized city by migratory wild birds. Therefore, wild bird habitats in urbanized areas should be carefully monitored for HPAIV.

Clinical neuropsychology in South Korea, albeit its relatively short history, has advanced dramatically. We review a brief history and current status of clinical neuropsychology in South Korea. The history, the educational pathway, the training pathway, the certification process, and careers in clinical neuropsychology in South Korea are reviewed. We have reviewed the neuropsychological services, including assessment and treatment, research on neurological and psychiatric populations, and neuropsychology education and the requirements related to education, training, and board examinations of those providing neuropsychological services in South Korea. We also describe how the Korean Society for Neuropsychology Research, the first and only meeting for neuropsychologists in the country established in 1999, has played a major role in how clinical neuropsychology is practiced and developed as a professional field in South Korea. Clinical neuropsychology in South Korea has achieved major progress over just a quarter of a century, and its future is promising in light of the increasing demand for neuropsychological services and advances in neuroscience in the country. Challenges that the community of clinical neuropsychologists are currently facing in South Korea, including formalizing neuropsychological curriculum and training programs and developing advanced credentialing procedures, are discussed.

Korea is participating in international collaboration activities since the selection of supercritical water-cooled reactor (SCWR) as one of the viable candidates for Generation IV reactor systems in 2002. The SCWR has been selected by Generation IV International Forum (GIF) since it is a very feasible candidate reactor system for a large-scale electricity production in commercially viable manner. However, the level of Korean participation is still limited to several key areas and the decision-making on whether going into full-scale research is yet to be made. In three circumstances it has been decided to launch a feasibility study in March 2007 to assess the domestic capability and resources as well as economics for development of an SCWR and to identify the required research areas. This paper introduces the project named 'A feasibility study for the development of an SCWR in Korea', which is sponsored by MEST (Ministry of Education, Science and Technology) in Korea. The main purpose of this study is to provide a basis for establishing a government policy in consideration of the unique domestic environment for SCWR development. This study includes three different areas of evaluation aspect, i.e., policy and environment, technology and safety, and economics. In policy and environment aspects, the needs of SCWR development is evaluated in terms of future electricity demand, reactor type strategy, fuel cycle policy, and available infrastructure in Korea, etc. In technology and safety aspects, evaluation is performed to identify the most optimum way of SCWR R and D strategy and several fundamental studies including heat transfer, code developments, and materials are performed in parallel. Finally, in economic aspect, the economic feasibility of SCWR development is assessed in comparison with the Korean nuclear power plants OPR1000 and APR1400 and other comparable overseas reactors. This study will be finished by 2010 and the results of the assessment will become a

Feasibility study of EEW application in Korea

At present, it seems almost impossible to predict where and how much strong a earthquake will happen within very limited time such as two or three days before it occurs. However, the advantage of modern electronic techniques can support us very fast communication tools around nation-wide area so that we can receive P- waves arrival information from seismic stations through communication lines before S-waves strike our living site. This is the key of EEW(Earthquake Early Warning) concept that is under development around world especially including Japan, United State of America, and Taiwan. In this pilot study we proposed the direction for developing Korean Earthquake Early Warning System. Considering the state of the art techniques used in Japan, USA and Taiwan, ElarmS would be more adaptable to Korea since ElarmS can work from the low limit of moderate earthquakes around magnitude 3.5, which would annually happen in Korea. We investigate empirical magnitude scaling relationship for South Korea using 27 events ranging in magnitude from 2.2 to 4.9 recorded by the Korea Institute of Geoscience And Mineral Resources (KIGAM) and the Korea Meteorological Administration (KMA) for 2007. We measure the maximum predominant period and the peak displacement or velocity amplitude from the first 4 seconds of P wave arrivals to derive period-magnitude and amplitude-magnitude scaling relationship, respectively. For the period-magnitude relationship, we find that 10 Hz low-pass filter yields better estimate than 3 Hz. This is because the magnitudes of most events used in this study are too small (<3.0). It is also shown that peak displacement for velocity instruments and peak velocity for accelerometers have their own magnitude scaling relationships, respectively. Thus, for the amplitude-magnitude relationship, like the relationships in northern California, two individual amplitude scaling relationships would be necessary.

The Conundrum of Demographic Aging and Policy Challenges: A Comparative Case Study of Canada, Japan and Korea

Directory of Open Access Journals (Sweden)

Susan A. McDaniel

2009-12-01

Full Text Available Some analysts lean toward comparative analyses of population aging, then draw potential policy implications. Others lean in the direction of attention to differences in policy regimes and then consider implications of population aging. Key differences among advanced societies may not emanate from demographic aging but from differences in how markets, states, and families work to redistribute societal benefits. In this paper, three countries with contrasting configurations of markets, states, and families, and at different stages of demographic aging, are compared and contrasted: Canada, Japan, and Korea. The paper has three objectives: 1 to outline key changes in population, family, and work in the three countries; 2 to consider how knowledge about these changes, their dynamics and interrelationships, is framed with respect to policy options; and 3 to compare Canada, Japan, and Korea in terms of the framing of policy challenges related to demographic aging. It is found that Canada is joining the longstanding pattern of Japan and Korea of late home-leaving by youth, meaning less effective time in the paid labour force. Little deep connection exists between population aging and economic productivity or labour force shortages. Differential labour market participation of women mediates the effects of population aging.

PRIMARY STUDENTS' STEREOTYPIC IMAGE OF INVENTOR IN KOREA

Full Text Available The purpose of this research is to compare the previous stereotypes of the scientist image and the current stereotypes of the inventor image among Korean students. For this purpose, three primary schools located in the metropolitan area of Korea were selected under a convenience sampling method, with one class selected for each of the 2nd, 4th, and 6th grades of each school. The conclusions of this research are as follows. First, analyzing students' stereotypes of the inventor image showed that older students had more stereotypes about inventors than younger students did. Second, as a result of analyzing the images according to each indicator, Korean students were found to have stereotypes about the inventor. Third, the symbol of research was expressed together with one of the science-related experiment tool and the making-related experiment tool. Fourth, primary students perceived the inventor as mainly male. Male students mostly drew male inventors and female students mostly drew female inventors. Based on the conclusions obtained through this research, various educational implications to be reflected in primary technology education were suggested to escape the stereotypes of the inventor’s image.

North Korea: a mercenary proliferator?

International Nuclear Information System (INIS)

Hemez, Remy

2015-01-01

After having recalled that North Korea possesses a rather advanced ballistic programme which has been started in the 1970 with the Chinese support, that North Korea is the fourth world producer of ballistic missiles, the author outlines that this country has become a major proliferator as it exports this production to different States and non-State actors. He recalls the long history of relationships between North Korea and terrorist organisations (even during the Cold War), comments the current and major support of North Korea to Hamas and Hezbollah in Gaza and in Lebanon. These relationships are then related with those these both organisations have with Syria and Iran who are in fact the relays between them and North Korea. The author explains why Hamas and Hezbollah must buy their weapons to such a far country: Iran is submitted to international sanctions, Iran and Syria want to avoid being banned from the international community for selling weapon to a terrorist (or so-said) organisation, and prices are rather competitive. If North Korea is also submitted to international sanctions, weapon smuggling seems to be institutional in this country. The author finally briefly evokes the issue of chemical weapons: North Korea possesses few thousand tonnes of these weapons, and could export them to non-state organisations

Current and anticipated uses of thermal hydraulic codes in Korea

In Korea, the current uses of thermal hydraulic codes are categorized into 3 areas. The first application is in designing both nuclear fuel and NSSS. The codes have usually been introduced based on the technology transfer programs agreed between KAERI and the foreign vendors. Another area is in the supporting of the plant operations and licensing by the utility. The third category is research purposes. In this area assessments and some applications to the safety issue resolutions are major activities using the best estimate thermal hydraulic codes such as RELAP5/MOD3 and CATHARE2. Recently KEPCO plans to couple thermal hydraulic codes with a neutronics code for the design of the evolutionary type reactor by 2004. KAERI also plans to develop its own best estimate thermal hydraulic code, however, application range is different from KEPCO developing code. Considering these activities, it is anticipated that use of the best estimate hydraulic analysis code developed in Korea may be possible in the area of safety evaluation within 10 years.

Koii(Public Doctor) System introduced into Taiwan in 1896 for the purpose of filling up medical vacuum of rural area and therefore spreading modern medical system all over Taiwan, was transplanted in 1913 into Colonial Korea for the same purpose. In terms of system itself Koii system in both areas were almost the same, but quite different in practices. First, Koiis in Taiwan was forced to write concrete medical report every month on the medical situation in the area under jurisdiction, whereas to those in Korea writing monthly report was not so compulsory. This difference resulted in some gaps in the quality of medical statistics of the two areas. Second, Unlike their counterparts in Korea, Koiis in Taiwan organized their own associations both locally and nationally and it helped to build up their own networks and share informations on medical situation including informations on infectious diseases. Third, Koiis in Taiwan formed more harmonious relationship between Taiwanese Police than their counterparts in Korea, which helped them to execute various medical activities in more comfortable environment. Taiwanese People went to medical institutions a lot more frequently than Korean People, and this difference was basically derived from the quite different density of Koii assignment in both areas. Korean People had to spend more time and money to utilize modern medical institutions than Taiwanese People did. The different density of Koii assignment also affected the results of prevention and eradication of infectious diseases; in Taiwan plague and small-pox has been successfully controled, whereas Chosun Government general was not so successful in controling infectious diseases including small-pox. Small-pox infected in Korea was about 6 times to Taiwan, and the number of death by small-pox was 9 times to Taiwan. One of the keys to this difference is the different role of Koiis. In Korea, Koiis could do little thing about infectious diseases mainly because of

In early start of monitoring, a pathway for high runoff volumes and peak flows during rainfall period towards downstream of a waterbody was provided from storm sewer network, but later on it was realized to deal with stormwater quantity and quality to develop new approaches and management techniques. In early 90’s NPS pollution issue was highlighted in korea, but only limited studies were conceded out up to the year 2000, however reasonably huge numbers of studies were directed for environmental science. After the recognition of NPS, Ministry of Environment in 1998 has introduced NPS as a major contributor in total maximum daily load management system (TPLMS) and waterbodies impairment, which is one of the guidelines of widespread water improvement strategies for main rivers. It contains a number of agendas that intention is to improve, maintain or restore the water quality in national water systems. It can be potted that stormwater management has evolved during the decades as of understanding with its impacts and it has been evolved from focusing on flood control to now incorporating control for volume, erosion and water quality, which is theoretically based on a watershed concept.

Disaster Vulnerability in South Korea under a Gender Perspective

Chung, Gunhui

2017-04-01

The most affected natural disaster has been flooding in South Korea, however, many unexpected natural disasters cause by snow or drought have become severe due to the climate change. Therefore it is very important to analyze disaster vulnerability under the unexpected climate condition. When the natural disaster happens, in many cases, female was more damaged than male because of the cultural and physical limitations. Disaster is never gender neutral. For example, four times as many female as male died in Indonesia tsunami. Therefore, it is very important to consider gender sensitivity in the disaster vulnerability to mitigate effects on the female. In this study, the current disaster management guideline in South Korea is investigated in the gender perspective and compared to the other countries. As a result, gender analysis in the disaster preparedness and response is not implemented in South Korea. Thus, the gender balanced disaster management guideline is newly proposed.

Full text: Nuclear power generation has assured the stable supply of energy, reduced national trade deficit, lowered electricity bill, and mitigated the air-pollution problem in Korea. As of 2005, Korea has 20 nuclear power plants in operation and 4 under construction. According to the recent 'Long-Term Electricity Supply Scheme', Korea will have 28 nuclear units in operation by 2017, which will consist of 45% of electricity generation. The 3rd 'Comprehensive Promotion Plan of Nuclear Energy' has been completed, which will constitute the national nuclear policy of Korea during the period of 2007 through 2011. According to the Plan, 1,000 MWe-sized OPRIOOO and 1,400 MWe-sized APR1400 will serve for large-scale electricity generation until 2025. Korea will commercialize 330 MWt-sized SMART for multi-use purpose such as seawater desalination, district heating, ship propulsion, and small-scale electricity generation. Korea has joined GIF and INPRO to develop advanced reactor concepts beyond the year of 2025: SFR for fast reactor program and VHTR for hydrogen production. Along with the Plan, the 'Medium and Long Term Nuclear R and D Program (2007-2011)' has been also formulated to support the Plan through systematic R and D work in the areas of: future reactor systems, nuclear safety, nuclear fuel cycles, radiation technology, and innovative nuclear power technology. The total 5-year R and D budget will be a little over 1 billion US dollars

WHAT IS KNOWN ON THE SUBJECT?: Despite the increased interest in nursing students' happiness in South Korea, few studies have attempted to identify factors influencing their happiness. Therefore, nursing educators should consistently investigate the factors influencing happiness and develop strategies to improve happiness among Korean nursing students. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study confirmed that there were positive correlations between grateful disposition, social support and happiness. In addition, grateful disposition and support from intimate people were identified as predictors of happiness in Korean nursing students. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Development of intervention programmes to help nursing students increase grateful disposition and support from intimate people may be helpful for improving happiness. These programmes can include activity, such as writing a gratitude journal, and extracurricular programmes, such as mentoring programmes between seniors and juniors and/or professor and student. Introduction Happiness is very important in the training and development of nursing students as future nurses. However, nursing students experience a high level of stress and low level of happiness in South Korea. Aim This study aimed to investigate factors that affect happiness among nursing students in South Korea. Method Data were collected from a total of 241 nursing enrolled in two 4-year baccalaureate nursing programmes in South Korea, using a self-administrated questionnaire. To identify predictors of happiness, stepwise regression analysis was conducted. Results The results indicated that grateful disposition and support from intimate people significantly predict happiness among Korean nursing students. These two factors accounted for 38.0% of the variance in happiness. Discussion This study indicated grateful disposition and support from intimate people as factors promoting happiness in nursing students. The findings

A total of 82 isolates of Colletotrichum species were obtained from anthracnose symptoms of highbush blueberry trees grown in the Gochang area of Korea during a disease survey in 2008. Out of the isolates, 75 were identified as Colletotrichum gloeosporioides and the others as C. acutatum based on their morphological and cultural characteristics. Twenty six of C. gloeosporioides isolates produced their teleomorph Glomerella cingulata in PDA culture. Three isolates of each C. gloeosporioides and C. acutatum caused anthracnose symptoms on the leaves by artificial inoculation, which were similar to what was observed in the orchards. Previously in Korea, only C. gloeosporioides has been reported as causing anthracnose in blueberries. This is the first report that C. acutatum causes anthracnose in the highbush blueberry in Korea.

Models of financial crises based on distortions in capital markets have strong implications for the behavior of investors leading up to crises. In this paper we evaluate the hypothesis that deregulation of financial markets in Korea provided the incentives and opportunities for a sequence of capital inflows and crisis. We show that deregulation was associated with a sharp declines in the franchise value of Korean banks. Banks responded by expanding their balance sheets and accumulating high r...

Household Arthropod Allergens in Korea

2009-01-01

Arthropods are important in human health, which can transmit pathogens to humans, parasitize, or produce important allergens. Allergy prevalence becomes higher in Korea recently as well as other developed countries in contrast to a decrease of infectious diseases. Allergic diseases caused by household arthropods have increased dramatically during the last few decades since human beings spend more their time for indoor activities in modernized life style. Household arthropods are one of the most common causes of allergic diseases. Biological characterization of household arthropods and researches on their allergens will provide better understanding of the pathogenesis of allergic diseases and suggest new therapeutic ways. Therefore, studies on arthropods of allergenic importance can be considered one of the major research areas in medical arthropodology and parasitology. Here, the biology of several household arthropods, including house dust mites and cockroaches, the 2 most well known arthropods living indoor together with humans worldwide, and characteristics of their allergens, especially the research activities on these allergens performed in Korea, are summarized.

Full text : This article describes the Nuclear age in Korea which began in 1959 when Korea Atomic Energy Research Institute (KAERI) was first established. Since then, Korea became one of the leading countries in the world nuclear technology and industry. In Korea, 20 nuclear power plants are currently in operation, which produced 34.1% of total electricity in 2009. Furthermore, 8 nuclear power plants are under construction. Eventually, Korea succeeded in exporting nuclear power plant to United Arab Emirates and research reactor to Jordan in 2009. The nuclear application can be divided into two fields. The first one is nuclear power production, and the other is radiation application. Due to the governmental promotion policy, the research activity on radiation and RI application is greatly rising in Korea. Korea Atomic Energy Research Institute (KAERI) and Korea Institute of Radiological and Medical Sciences (KIRAMS) are two leading research institutes in this field. KAERI is conducting RI production and neutron research by using research reactor, and radiation application research such as radiation processing, biotechnological and agricultural application, and cyclotron application. KIRAMS is dedicated to the research on the medical application of radiation. Advanced Radiation Technology Institute (ARTI), constructed in 2006 as a sub organization of KAERI, is a major research institute for radiation application to material engineering, agriculture, biotechnology, environmental technology, and cyclotron beam application. ARTI is equipped with various radiation facilities such as Co-60 irradiation facility (490 kCi and 3 kCi), gamma phytotron, gamma cell, electron beam irradiator, ion implanter, and 30 MeV cyclotron. In material engineering field, new industrial and biomedical materials (carbon fiber filament, composite electrolyte, fuel cell membrane, hydrogels) are developed by radiation processing of polymer materials. In agricultural area, new plant varieties

This cross-sectional study was done to identify and determine the socio-demographic and health-related factors associated with diabetic retinopathy and nephropathy screening in Korea. Participants included 2,660 adults, aged 40 or older, with diabetes. Of the 2,660 adults, 998 (37%) and 1,226 (46.1%) had received a diabetic retinopathy and a nephropathy screening within one year, respectively. Regarding retinopathy, subjects older than 65, living in urban areas, with high educational levels, and with self-reported "unhealthy" status were likely to receive annual screening. Subjects living in urban areas, with higher educational levels, with self-reported "fair" or "unhealthy" status, and with 1 to 2 co-morbidities were likely to receive annual nephropathy screening. The Korea Composite Stock Price Index (KOSPI) continued to rise until 2007 when it started to decline over the subsequent years, following the same curve as the diabetic retinopathy and nephropathy screening rates during that time. Together with the financial matter, lack of patient education proved to be a hindrance to diabetes-related screening. The relatively low screening rates in Korea compared to the Western countries are likely to be due to the difference in the health system, economic situations and national demographics.

A missiological exploration of Australian missionary James Noble Mackenzie�s ministry to lepers in South Korea

Full Text Available The history of Australian Presbyterian Mission in Korea (APM is not comprehensive, nor the study of missiology that addresses the marginalised. This study of the ministry of APM missionary, J.N. Mackenzie, to lepers in Japanese-occupied Korea, adds significantly to both these areas. An understanding of the role and methods of Mackenzie�s missionary activities among the marginalised in Korea can encourage today�s Church to effectively restore the marginalised in society, moving from Church doctrine to practical reproduction of the example of Jesus recorded in Mark�s gospel. Using original and published sources, the study examines the social conditions in which Mackenzie found Korean lepers, their historic treatment and government policies and the growth of his holistic mission, with its methods and fruits. Mackenzie�s work is documented with recorded data included to demonstrate its Christ-like effectiveness both spiritually and physically. By tracing Mackenzie�s work with lepers, it is clear that holistic mission can helpfully impact the situation of the most marginalised. Mackenzie�s work expanded dramatically, churches were formed and it even created cured evangelists, making it a useful model for mission work among the marginalised. Mackenzie�s work played a significant part in the Church and National history of Korea and presented a new path in the mission work of APM. It has the potential to influence modern mission in being �as Christ� to the marginalised and thus to impact the society. This study has given a unique perspective on the history and theology of mission to the poor and traditionally powerless in society.Intradisciplinary and/or interdisciplinary implications: Traditional views of history, theology and missiology have focussed on the ruling classes and urban societies. A perspective of the marginalised encourages a shift in these as it can be seen that the rural poor responded to holistic ministry and affected

Clonorchis sinensis is currently the most important parasite affecting public health problems in the Republic of Korea. We investigated the prevalence of C. sinensis infection among residents living along 5 major rivers in Korea. A total of 42,562 individual stool samples were collected from 37 localities and examined using the formalin-ether sedimentation technique. Helminth eggs were detected in 4,052 (9.5%) residents and 3,586 (8.4%) were infected with C. sinensis. The egg positive rate of C. sinensis in Nakdong, Seomjin, Geum, Yeongsan, and Han River was 11.7%, 9.9%, 6.5%, 3.1%, and 1.0%, respectively. The overall prevalence of clonorchiasis by sex was 11.2% in males and 6.2% in females. The age-prevalence was the highest in the 50-59 years band. It has been reconfirmed that the endemicity of clonorchiasis is higher in southern areas of Korea, especially along Nakdong and Seomjin Rivers. A combination of continuous control programs with health education initiatives is urgently required in these highly endemic areas of clonorchiasis in Korea.

Full Text Available Several epidemiologic studies suggested that osteoporosis and osteoporotic fractures are not uncommon in South Korea. However, these previous cohort studies had limitations that may have influenced their results and the generalizability of the study conclusions, including small sample sizes, inclusion of only women, enrollment of participants from specific areas, and nonrandom selection of participants. Recently, epidemiologic studies using a nationwide claim register have been performed to overcome these limitations through collaboration between the Korean Society of Bone and Mineral Research and Health Insurance Review Assessments. Our review of the Korean Nationwide-database Osteoporosis Study could be helpful to obtain accurate incidence and prevalence estimations of osteoporosis and osteoporosis-related fractures in Korea.

Human Taeniasis in the Republic of Korea: Hidden or Gone?

Science.gov (United States)

2013-01-01

History and current status of human taeniasis in the Republic of Korea, due to Taenia solium, Taenia asiatica, and Taenia saginata, are briefly reviewed. Until the 1980s, human taeniasis had been quite common in various localities of Korea. A study from 1924 reported 12.0% egg prevalence in fecal examinations. Thereafter, the prevalence of Taenia spp. ranged from 3% to 14% depending on the time and locality. Jeju-do, where pigs were reared in a conventional way, was the highest endemic area of taeniasis. An analysis of internal transcribed spacer 2 and mitochondrial cytochrome c oxidase 1 genes of 68 taeniasis cases reported from 1935 to 2005 in Korea by a research group revealed the relative occurrence of the 3 Taenia spp. as follows: T. solium (4.4%), T. asiatica (75.0%), and T. saginata (20.6%). However, national surveys on intestinal helminths conducted every 5 years on randomly selected people revealed that the Taenia egg prevalence dropped from 1.9% in 1971 to 0.02% in 1997 and finally to 0.0% in 2004. With the exception of 3 egg-positive cases reported in 2008 and 2 worm-proven cases in 2011, no more cases have been officially recorded. Based on these surveys and also on other literature, it can be concluded that taeniasis has virtually disappeared from Korea, although a few sporadic cases may remain hidden. Human cysticercosis is also expected to disappear within a couple of decades in Korea. PMID:23467688

2014-12-01

This paper traces how Koreans of north area became medical doctors in colonial Korea. Most of the past research have focused only on the well-known medical doctors, or even when they discussed a great number of doctors, many research tended to only pay attention to the explicit final results of those doctors. This research, on the other hand, includes ordinary medical doctors as well as the renowed ones, and adjusts the focus to the lifetime period of their growth and activities. As a result, the misunderstanding and obscurity about the Korean medical doctors of north area during this period have been cleared. The new characteristics of the Korean medical doctors of this period have been found, along with their embodiment of historical significance. At the time, Koreans had to get through a number of qualifications in order to become doctors. First is the unique background of origin in which the family held interest in the modern education and was capable of supporting it financially. Second is the long-term status of education that the education from elementary to high school was completed without interruption. Third is the academic qualification that among various institutions of higher education, medical science was chosen as a major. Fourth is the condition of career in which as the career as a doctor had consistently continued. Thus, in oder to become a modern medical doctor, Koreans had to properly complete these multiple steps of process. The group of Korean medical doctors in north area, which was formed after getting through these series of process, possessed a number of characteristics. Firstly, as the upper-middle classes constituted the majority of medical doctors in Korea, the societal status of doctors rose and the foundation for the career as a doctor to be persisted as the family occupation settled. Secondly, the research career and academic degree became the principal method to escape from the discrimination and hierarchy existed between doctors. A

2014-01-01

The IAEA safety requirements represent a consensus view of the IAEA's member states and encompass the recommendations of international experts for the safety of the research reactor. The IAEA safety standards are acknowledged as a global standard by most countries in the world. Therefore, it is desirable to harmonize domestic safety requirements with those of the IAEA. Also, since the IAEA safety requirements include international endeavors to strengthen nuclear safety and to apply the latest nuclear safety technologies to nuclear facilities, a comparative analysis of the safety requirements of the IAEA and Korea for the research reactor will be beneficial to obtaining the insights to improve regulations of the research reactor in Korea. For the reason, a comparative study has been conducted for the research reactor operation safety requirements of the IAEA and Korea in this paper. This paper briefly introduced operation safety requirements in the NS-R-4, analysis methods of this study, and the analysis results. A comparative study has been performed on research reactor operation safety requirements of the IAEA and Korea. This study has identified some gaps in operation safety requirements for the NPP of Korea, comparing with those for the research reactor of the IAEA in the following areas: periodic safety assessment, utilization and modification of the reactor, extended shutdown, inspection/testing/maintenance, operating organization, emergency planning, and commissioning

Many studies have sought to determine the predictors of institutionalization of patients with dementia. Such studies, performed in developed western societies, have come to various conclusions which may not be supported in an East Asian culture such as that found in Korea. This study aimed to determine the factors that predict institutionalization of patients in Korea diagnosed with dementia. Seventy-nine cases (37 institutionalized, 42 community-dwelling) in the Kwangju area were evaluated for patient characteristics, severity of dementia symptoms, caregiver characteristics, burden and distress. Logistic regression was performed to determine predictors of actual institutionalization. Six predictors of institutionalization were identified. Of these, three were patient-related factors: higher score on the Clinical Dementia Rating, higher score on the Brief Psychiatric Rating Scale, and shorter duration of dementia. The other three were caregiver-related factors: younger age, higher education (formal schooling), and higher cost of home care. As seen in previous western studies, institutionalization of dementia sufferers was influenced by both patient and caregiver factors. But, the specific predictors and their relative influences might be explained best by the particular social, cultural and economic situation in Korea. This study was the first of its kind in Korea and, as such, could serve as a reference for future intra-cultural and cross-cultural comparisons. Copyright 2002 John Wiley & Sons, Ltd.

Full Text Available In this study, total gaseous mercury (TGM concentrations were measured on Yongheung Island off the coast of Korea between mainland Korea and Eastern China in 2013. The purpose of this study was to qualitatively evaluate the impact of local mainland Korean sources and regional Chinese sources on local TGM concentrations using multiple tools including the relationship with other pollutants, meteorological data, conditional probability function, backward trajectories, and potential source contribution function (PSCF receptor modeling. Among the five sampling campaigns, two sampling periods were affected by both mainland Korean and regional sources, one was caused by mainland vehicle emissions, another one was significantly impacted by regional sources, and, in the remaining period, Hg volatilization from oceans was determined to be a significant source and responsible for the increase in TGM concentration. PSCF identified potential source areas located in metropolitan areas, western coal-fired power plant locations, and the southeastern industrial area of Korea as well as the Liaoning province, the largest Hg emitting province in China. In general, TGM concentrations generally showed morning peaks (07:00~12:00 and was significantly correlated with solar radiation during all sampling periods.

The purpose of this study was to establish a basis for improving or strengthening the preventive strategy against scrub typhus in Korea by comparing and analyzing the difference of prevention behaviors contributing to the occurrence of scrub typhus in Japan and Korea. The survey was carried out in Jeollabuk-do, which is a high risk and high incidence area, and Fukuoka Prefecture, which is a high risk and low incidence area. The study included 406 Korean farmers and 216 Japanese farmers. Data were collected through face-to-face surveys by interviewers who had completed standardized education. Korean farmers have a higher percentage of agricultural working posture that involved contact with weeds than Japanese farmers (pwork was more appropriate for Japanese farmers than for Korean farmers (pwork was lower in Korea than in Japan, lower in men than women, and lower in part-time farmers than full-time farmers (p<0.05). This study suggests that it is reasonable to develop and provide a program that can improve the level of preventive behavior taking into consideration the characteristics of the subject in order to reduce the incidence of diseases in high-risk areas for scrub typhus.

International Nuclear Safety Experts Conclude IAEA Peer Review of Korea's Regulatory System

International Nuclear Information System (INIS)

2011-01-01

Full text: An international team of senior nuclear safety experts concluded today a two-week mission to review the regulatory framework for nuclear safety in the Republic of Korea. The team identified good practices and gave advice on areas for future improvements. The IAEA has conveyed the team's main conclusions to the Government of Korea, while the final report will be submitted by the end of summer 2011. At the request of the Korean Government, the IAEA assembled a team of 16 senior regulatory experts from 14 nations to conduct the Integrated Regulatory Review Service (IRRS) mission involving the Korean Ministry for Education, Science and Technology (MEST) and the Korean Institute for Nuclear Safety (KINS). The mission is a peer-review based on the IAEA Safety Standards. ''This was the first IRRS mission organized after Japan's Fukushima Daiichi nuclear accident and it included a review of the regulatory implications of that event,' explains Denis Flory, IAEA Deputy Director General and Head of the Department of Nuclear Safety and Security. William Borchardt, Executive Director of Operations from the US Nuclear Regulatory Commission and Team Leader of this mission commended the Korean authorities for their openness and commitment to sharing their experience with the world's nuclear safety community. ''IRRS missions such as the one that was just concluded here in the Republic of Korea are crucial to the enhancement of nuclear safety worldwide,'' he said. The IRRS team reviewed Korea's current regulatory framework while acknowledging the fact that the country's Government has already decided to establish, as of October 2011, a new independent regulatory body to be called Nuclear Safety Commission (NSC). As a consequence, KINS role will be as a regulatory expert organization reporting to the NSC, while MEST's role will be restricted to promoting the utilization of nuclear energy. The IRRS team identified particular strengths in the Korean regulatory system

We investigated similarities and differences in clinical supervision in two cultures: South Korea and the United States The study had two parts: (1) a test of the cross-cultural equivalence of four supervision measures; and (2) a test of two competing models of cultural differences in the relations among supervisory style, role difficulties, supervisory working alliance, and satisfaction with supervision. Participants were 191 South Korean and 187 U.S. supervisees currently engaged in clinical supervision. The U.S. measures demonstrated sufficient measurement equivalence for use in South Korea. Cultural differences moderated the relations among supervisory styles, role difficulties, supervisory working alliance, and supervision satisfaction. Specifically, the relations among these variables were significantly stronger for U.S. than for South Korean supervisees. Implications for theory, research, and practice were discussed.

Nuclear program of South Korea

Slightly larger than Portugal, South Korea comprises the lower half on the Korean Peninsula, covering approximately 38 thousand square miles. the Republic of Korea (South Korea) was established in 1948, and until 1962 the country grew slowly. However, through a series of five-year economic plans initiated by South Korean President Park Ching Hee, South Korea has since created an export-oriented economy, which now plays a major role in regional as well as global trade. South Korea has been forced to constantly upgrade its power generation structure in order to sustain the explosive growth it has experienced. Nuclear power has been a major player in this expansion and is expected to play an ever-increasing role. The country presently operates nine nuclear reactors with a total net generating capacity of 7,266 MWe. By the year 2006, the nuclear program is scheduled to grow to 27 reactors, with a net generating capacity exceeding 23 thousand MWe. Once this goal is reached, nuclear-generated power would account for more than 40 percent of the country's total installed electrical capacity

This study examines contributing factors of alcohol misuse among college students in South Korea and the U.S. Exploratory factor analyses (EFA) on measurements of alcohol expectancy, alcohol efficacy, and accommodation resulted in social and personal causes for alcohol misuse. Social causes alone predicted alcohol misuse for both countries. Social factors constituted a much stronger predictor of alcohol misuse among South Korean students than among American students. Practical implications for effective deterrence of student binge drinking are discussed.

Full Text Available This paper is based on ongoing research into the gendered use of mobile convergent media in the Asia-Pacific region. In particular, what role does the cute have and how does it correlate with types of consumption? As a region, the Asia-Pacific is marked by diverse penetration rates, subject to local cultural and socio-economic nuances. Two defining locations - Seoul (South Korea and Tokyo (Japan - are seen as both mobile centres and gaming centres which the world looks towards as examples of the future-in-the-present. Unlike Japan, which pioneered the keitai (mobile IT revolution with devices such as i-mode, South Korea has become a centre for mobile DMB (Digital Multimedia Broadband with the successful implementation of TV mobile phones (TU mobile in 2005. One of the key features of mobile media technologies is the attempt by the industry to find the next killer application . One such application is the possibility of online multiplayer games accessed through mobile (broadband telephonic devices such as MMO golf RPG Shot Online (a golf game for mobile phones. Amongst this frenzy of trend spotting and stargazing, Seoul as a mobile broadband and gaming centre provides a curious case study for the social and cultural intricacies informing the rise of gaming as an everyday practice for many Koreans.This article begins by outlining the game play and technoculture particular to South Korea and then explores the phenomenon of Kart Rider in South Korean gaming cultures - and its perception/ reception outside Korea - to sketch some of the issues at stake in playing it cute (particularly in the form of cute avatars, consuming Korea and the endurance of co-present communities. In particular, it contemplates the implications of current emerging online mobile gaming genres such as so-called female games such as the cute' Kart Rider in order to think about changing modes of game play and attendant social spaces.

A Study on the Origins of Cultural Films in Korea: A Focus on Films by the Japanese Government-General of Korea

Full Text Available The term "cultural film" was coined in Korea under the Japanese rule, and it had been used as a general term for nonfiction films since the Korean liberation until the 1980s. However, unlike the term "documentary film," cultural film contains implications of propaganda film, controlled and produced as part of cultural and public relations policies of the government, thus it had been seldom studied for a long time. The term “cultural film” did not mean a film genre in the beginning. Therefore it is impossible to conceptualize the term based on common formats or contents of the films which have been called “cultural films.” Cultural films have been generally recognized as nonfiction films, and therefore documentary films. Yet in the production and distribution sites, fiction films and even animations were considered cultural films. In order to delve into the nature of cultural film, we have to reexamine the process in which the proper noun “Cultural Film” became a common noun. This paper attempts to explore the historical context in which the term “cultural film” was coined and used in the colonial Korea, when cultural films began to be produced. I examine the overall time period in which: 1 the concept of nonfiction film was first introduced in the Motion Picture Censorship Regulation, 2 the term “cultural film” became legally stipulated at a time when national policies were being established as Korea experienced the Manchurian Incident and the Sino-Japanese War, and 3 “cultural films” were screened mandatorily as “national films” that the nation had to foster through the Japan Film Law and Chosôn Film Act.

Online health information is a critical resource for health consumers. Nursing professionals need to be eHealth literate to support patients and their families. The purpose of the study was to explore eHealth literacy skills among undergraduate nursing students in the U.S. and South Korea. One hundred and sixty-nine undergraduate nursing students in two universities, one in the southern area of the U.S. and one in the eastern area of South Korea, participated. Participants were asked to complete the eHealth Literacy Scale. The majority of participants perceived that the Internet is a useful or very useful tool in helping them make health-related decisions. The participants either agreed or strongly agreed with the 7 items of the eHealth literacy scale except an item such as they can call high to low quality of online health information. The U.S students have higher mean scores of all eHealth literacy items than students of South Korea.

Hoabin Hong

2016-08-01

Full Text Available The anisotropy of magnetic susceptibility (AMS of late Cretaceous ash-flow tuffs in Chisulryoung Volcanic Formation, southeastern Korea was studied to define the primary pyroclastic flow azimuth. AMS data revealed a dominant oblate fabric with a tight clustering of k3 (minimum axis of magnetic susceptibility and shallow dispersal of k1 (maximum axis of magnetic susceptibility and k2 (intermediate axis of magnetic susceptibility. Dominance of oblate fabrics indicates clast imbrications imposed by compaction and welding. Flow azimuth inferred from AMS data indicates the nearby intrusive welded tuff (IWT as the source of calderas for ignimbrites. Such an inference is supported by geologic investigations, in which the IWT displays eutaxitic textures nearly parallel to its subvertical contacts. The results are compatible with a unique prolate fabric and an anomalously high inclination observed for the IWT, possibly produced by rheomorphic flows as the welded tuff is squeezed along the rough-surfaced dyke walls due to agglutination.

Foods grown in organic production systems have been described as representing an increased risk to public health compared with foods from conventional production. Leafy vegetables (spinach, romaine lettuce, and green sesame leaves) grown in organic and conventional systems were collected from various areas in Korea and examined using standard culture methods to compare the microbiological quality of the produce grown in the two agricultural systems. The 354 samples of these leafy vegetables were analyzed for levels of indicator bacteria (aerobic bacteria, coliforms, and Escherichia coli) and the prevalence of the pathogens Staphylococcus aureus, E. coli O157:H7, Listeria monocytogenes, Bacillus cereus, and Salmonella. Aerobic bacteria and coliforms were detected in all vegetable types, but nonpathogenic E. coli was below the limit of detection in all samples. B. cereus was the most prevalent pathogen, found on 7 (11.1%) of the 63 organic spinach samples. The prevalence of S. aureus was highest in organic sesame leaves; it was found on 5 (8.0%) of the 63 samples. The prevalence of L. monocytogenes was highest on organic romaine lettuce and spinach; it was found in 4 (6.4%) of 63 samples of each type of vegetable. E. coli O157:H7 found on only 1 (1.58%) of 55 conventional spinach samples. These results suggest that farming type at most only slightly affects the hygienic quality of leafy vegetables, and no effect was found for sample collection area. Salmonella was not isolated from any of the conventional or organic leafy vegetables. These results do not support the hypothesis that organic produce poses a substantially greater risk of pathogen contamination than does conventional produce.

To estimate available geothermal energy and to construct temperature at depth maps in Korea, various geothermal data have been used. Those include 1560 thermal property data such as thermal conductivity, specific heat and density, 353 heat flow data, 54 surface temperature data, and 180 heat production data. In Korea, subsurface temperature ranges from 23.9 C to 47.9 C at a depth of 1 km, from 34.2 C to 79.7 C at 2 km, from 44.2 C to 110.9 C at 3 km, from 53.8 C to 141.5 C at 4 km, and from 63.1 C to 171.6 C at 5 km. The total available subsurface geothermal energy in Korea is 4.25 x 10{sup 21} J from surface to a depth of 1 km, 1.67 x 10{sup 22} J to 2 km, 3.72 x 10{sup 22} J to 3 km, 6.52 x 10{sup 22} J to 4 km, and 1.01 x 10{sup 23} J to 5 km. In particular, the southeastern part of Korea shows high temperatures at depths and so does high geothermal energy. If only 2% of geothermal resource from surface to a depth of 5 km is developed in Korea, energy from geothermal resources would be equivalent to about 200 times annual consumption of primary energy ({proportional_to}2.33 x 10{sup 8} TOE) in Korea in 2006.

Taikyu Ree (1902-92) and Seung Ki Li (1905-96) were the most famous and influential scientists in twentieth-century Korea. Trained at Kyoto Imperial University during the Japanese occupation period (1910-45), both followed parallel career paths until 1945 but after that year those paths began to diverge. In 1948 Taikyu Ree moved to the University of Utah where he ran an informal graduate programme to train Korea chemists during the 1950s and 1960s. He became a model scholar in pursuit of knowledge for its own sake. In 1950 Seung Ki Li moved to North Korea where he succeeded in industrialising a new synthetic fibre from polyvinyl alcohol. He became a popular hero who demonstrated the utility of science. His success also helped Kim Il Sung, North Korea dictator, to consolidate his political ideology of Self-Reliance. Despite their different career patterns in very different circumstances, they shared something common; apolitical views and commitment to their work. An investigation of the careers of these two chemists illustrates the interwoven scientific, ideological and economic developments of South and North Korea during the second half of the twentieth century.

World Health Organization has asserted that mental illness is the greatest overriding burden of disease in the majority of developed countries, and that the socioeconomic burden of mental disease will exceed that of cancer and cardiovascular disorders in the future. The life-time prevalence rate for mental disorders in Korea is reported at 27.6 %, which means three out of 10 adults experience mental disorders more than once throughout their lifetime. Korea's suicide rate has remained the highest among Organization for Economic Cooperation and Development (OECD) nations for 10 consecutive years, with 29.1 people out of every 100,000 having committed suicide. Nevertheless, a comprehensive study on the mental health services and the Research and Development (R&D) status in Korea is hard to find. Against this backdrop, this paper examines the mental health services and the R&D status in Korea, and examines their shortcomings and future direction. The paper discusses the mental health service system, budget and human resources, followed by the mental health R&D system and budget. And, by a comparison with other OECD countries, the areas for improvement are discussed and based on that, a future direction is suggested. This paper proposes three measures to realize mid and long-term mental health promotion services and to realize improvements in mental health R&D at the national level: first, establish a national mental health system; second, forecast demand for mental health; and third, secure and develop mental health professionals.

In this study, we investigated the contributions of major emission source categories located upwind of South Korea to Particulate Matter (PM) in South Korea. In general, air quality in South Korea is affected by anthropogenic air pollutants emitted from foreign countries including China. Some studies reported that foreign emissions contributed 50 % of annual surface PM total mass concentrations in the Seoul Metropolitan Area, South Korea in 2014. Previous studies examined PM contributions of foreign emissions from all sectors considering meteorological variations. However, little studies conducted to assess contributions of specific foreign source categories. Therefore, we attempted to estimate sectoral contributions of foreign emissions from China to South Korea PM using our air quality forecasting system. We used Model Inter-Comparison Study in Asia 2010 for foreign emissions and Clean Air Policy Support System 2010 emission inventories for domestic emissions. To quantify contributions of major emission sectors to South Korea PM, we applied the Community Multi-scale Air Quality system with brute force method by perturbing emissions from industrial, residential, fossil-fuel power plants, transportation, and agriculture sectors in China. We noted that industrial sector was pre-dominant over the region except during cold season for primary PMs when residential emissions drastically increase due to heating demand. This study will benefit ensemble air quality forecasting and refined control strategy design by providing quantitative assessment on seasonal contributions of foreign emissions from major source categories.

The recent increase in surface particulate matter (PM) concentrations in South Korea is intriguing due to its disagreement with current intensive emission reduction efforts. The long-term trend of surface PM concentrations in South Korea declined in the 2000s, but since 2012 its concentrations have tended to increase, resulting in frequent severe haze events in the region. This study demonstrates that the interannual variation of surface PM concentrations in South Korea is not only affected by changes in local or regional emission sources, but also closely linked with the interannual variations in regional ventilation. Using EPA Community Multiscale Air Quality modeling system, a 12-year (2004-2015) regional air quality simulation was conducted to assess the impact of the meteorological conditions under constant anthropogenic emissions. In addition, NOAA HYSPLIT dispersion model was utilized to estimate the strength of regional ventilation that dissipates local pollutions. Simulated PM concentrations show a strong negative correlation (i.e. R=-0.86) with regional wind speed, implying that reduced regional ventilation is likely associated with more stagnant conditions that cause severe pollutant episodes in South Korea. We conclude that the current PM concentration trend in South Korea is a combination of long-term decline by emission control efforts and short-term fluctuations in regional wind speed interannual variability. When the meteorology-driven variations are removed, PM concentrations in South Korea have declined continuously even after 2012, with -1.45±0.12, -1.41±0.16, and -1.09±0.16 mg/m3 per year in Seoul, the Seoul Metropolitan Area, and South Korea, respectively.

Seawater samples from major enclosed bays, fishing ports, and harbors of Korea were analyzed to determine levels of tributyltin (TBT) and booster biocides, which are antifouling agents used as alternatives to TBT. TBT levels were in the range of not detected (nd) to 23.9 ng Sn/L. Diuron and Irgarol 1051, at concentration ranges of 35-1360 ng/L and nd to 14 ng/L, respectively, were the most common alternative biocides present in seawater, with the highest concentrations detected in fishing ports. Hot spots were identified where TBT levels exceeded environmental quality targets even 6 years after a total ban on its use in Korea. Diuron exceeded the UK environmental quality standard (EQS) value in 73% of the fishing port samples, 64% of the major bays, and 42% of the harbors. Irgarol 1051 levels were marginally below the Dutch and UK EQS values at all sites. Copyright © 2013 Elsevier Ltd. All rights reserved.

Since 1979, activities on the developments of PIRA methodologies and procedures, and its application as well as the safety goal establishment have increased because of the important benefits which may be derived from the uses of PIRA. PIRA is used in many areas including safety evaluation, preparation of basis of standards, siting of nuclear facilities, operator training, energy technology comparison, design, safety improvement(backfitting), operating procedure changes, test and maintenance procedure development, safety goal establishment, and plant availability improvement. Especially, vendor countries are utilizing PIRA methods for parts of the safety demonstration for proposed power plants. In this connection, Korea began to take a interest in PIRA in 1979. Since then, basic methodologies and computer codes of PIRA have been introduced, modified, and applied to Korea nuclear power plants

Korea is the world's 14. largest economy but the eighth largest emitter of CO_2 as of 2013, due largely to an energy-intensive industry structure. Although it has continuously reduced its dependency on petroleum since it introduced the Energy Master Plan in 2008, the relative portion of non-fossil fuel sources, such as renewable energy, is still marginal at best (representing less than 10 percent of the total energy portfolio). In particular, it is difficult for Korea to increase the portion of renewables for various reasons. In this context, Korea has tried to find an adequate role in fighting against climate change.

Superconductivity research in Korea was firstly carried out in the late 70's by a research group in Seoul National University (SNU), who fabricated a small scale superconducting magnetic energy storage system under the financial support from Korea Electric Power Company (KEPCO). But a few researchers were involved in superconductivity research until the oxide high Tc superconductor was discovered by Bednorz and Mueller. After the discovery of YBaCuO superconductor operating above the boiling point of liquid nitrogen (77 K)(exp 2), Korean Ministry of Science and Technology (MOST) sponsored a special fund for the high Tc superconductivity research to universities and national research institutes by recognizing its importance. Scientists engaged in this project organized 'High Temperature Superconductivity Research Association (HITSRA)' for effective conducting of research. Its major functions are to coordinate research activities on high Tc superconductivity and organize the workshop for active exchange of information. During last seven years the major superconductivity research has been carried out through the coordination of HITSRA. The major parts of the Korea's superconductivity research program were related to high temperature superconductor and only a few groups were carrying out research on conventional superconductor technology, and Korea Atomic Energy Research Institute (KAERI) and Korea Electrotechnology Research Institute (KERI) have led this research. In this talk, the current status and future plans of superconductivity research in Korea will be reviewed based on the results presented in interim meeting of HITSRA, April 1-2, 1994.

2006-12-01

Full Text Available In the second report in our series on the historical investigation on the introduction of western psychiatry into Korea, authors deal with the status of psychiatric education during the Japanese forced annexation of Korea. The first lecture on psychiatry in Korea under the title "Mental Diseases" was held in Dae-han-eui-won around 1910. In 1913, the Department of Psychiatry branched off from the Department of Internal Medicine of Chosen-sotoku-fu-iing, the Colonial Governmental Clinic, the successor of Dae-han-eui-won. The chairman, Professor Suiju Sinji; and the Korean assistant Sim Ho-seop administered the psychiatric ward with 35 beds. Since 1913, an Australian missionary psychiatrist, Dr. McLaren began to teach neurology and psychiatry at Severance Union Medical College and established a Department of Psychiatry in 1923. Dr. McLaren was a faithful Christian and open minded toward Oriental religious thought such as in Buddhism and Taoism. He devoted himself to the humanitarian care of mentally ill patients and served there until 1937 when he had to leave the land due to Japanese persecution. His disciple, Dr. Lee Jung Cheol succeeded the chair of the Psychiatric Department of Severance Medical College and served until 1939. In 1916, Keijo(Seoul Medical College was established and in 1928, Keijo Teikoku Daigaku(Imperial University. From 1929 to 1941, the Department of Neurology and Psychiatry of Keijo Imperial University grew under the chairmanship of Professor Kubo Kioji followed by Professor Watanabe until 1945. Many assistants including a few Koreans were gathered to the Department for training and research. The main textbook used for the psychiatric education for medical students in Korea was on Kraepelinian German Psychiatry translated and edited by Japanese psychiatrists. Lectures and clerkships for Neurology and Psychiatry were allocated generally in the curriculum for senior students for weekly 1-3 hours. Postgraduate professional

LONGEVITY IN NORTH KOREA AND SOUTH KOREA: PREVALENCE OF CENTENARIANS IN ONE THE POOREST AND ONE OF THE RICHEST NATIONS.

Schwekendiek, Daniel

2018-03-01

Over recent decades, economic living conditions have dramatically improved in South Korea, which now represents one of the most developed nations. At the same time, its twin in the North remains one of the poorest countries on earth. Thus, the Korean peninsula represents a unique historical experiment that allows for study of the effects of environment on human development under a variety of ceteris paribus cultural, genetic and climatic conditions. Previous studies comparing the biosocial performances of the two Koreas have focused on indicators such as weight, height, mid-upper arm circumference and age at menarche. The purpose of the present study was to investigate longevity based on the number of centenarians living in the two Koreas by drawing on censuses implemented around 1925 and 2010. The study found that North Korea had some 0.7 centenarians per one million persons in 1925, and this rate moderately improved to 2.7 around 2010. Conversely, rates skyrocketed in South Korea from 2.7 in 1925 to 38.2 around 2010. This suggests that the rate of centenarians in North Korea around 2010 corresponds to that of South Korea in 1925, suggesting a chronological lag in delayed human development of some 85 years. The prevalence of centenarians is fourteen times higher in contemporary South Korea compared with the North - broadly confirming previous biosocial studies on the two Koreas and two Germanies reporting improved human development in market-oriented systems compared with socialist ones.

Mining is a major industrial business of North Korea accounting for significant portion of an export for North Korean economy. However, due to its veiled political system, details of mining activities of North Korea is rarely known. This study investigated mining activities of Rakyeon Au-Ag mine, North Korea based on remote sensing based multi-temporal observation. To monitor the mining activities, CORONA data acquired in 1960s and 1970s, SPOT and Landsat data acquired in 1980s and 1990s and KOMPSAT-2 data acquired in 2010s are utilized. The results show that mining activities of Rakyeon mine continuously carried out for the observation period expanding tailing areas of the mine. However, its expanding rate varies between the period related to North Korea's economic and political situations.

Full Text Available This paper presents an attempt to explain changes of China’s dominant ideology, the socialist ideology identified in and through linguistic expressions. By analysing from a historical perspective the meanings potential of the word Korea with its correlated expressions in Chinese, it highlights how deeply the way of referring to two Koreas has been influenced under the traditional ideology of the Chinese society, manipulated by the communist ideology in socialist China and challenged by less powerful yet emerging ideologies in market-oriented China. With the major linguistic references in Chinese to two political entities in the Korean peninsula, North and South Korea, the paper studies the relationship between ideological changes in modern Chinese society and linguistic expressions that, as part of the system of language, reflect ideological investments in and political implications of the changes. Added with a translation-related case study with a focus of emphasis on the word Korea, it concludes that with a flourishing of cultural pluralism in China, usually a forerunner of political pluralism, less dominant ideologies do compete with the official ideology in various ways and forms, and the competition can be traced and identified in and through linguistic expressions. In other words, given the political and economic dynamics of China in the past half century, change of linguistic expressions may indicate, in one way or another, the wax and wane of the Chinese dominant socialist ideology in a dialectical sense.

New beauty ideals and particular types of plastic surgery beauty have emerged in South Korea from the early twenty-first century. By defining Gangnam-style plastic surgery as a hybrid of old Westernized beauty ideals and a new science of beauty with variations and contradictions, I intend to twist the simplistic understanding of non-Western plastic surgery as an effort to resemble the white westerner's body. I also draw political implications from a case of monstrous Gangnam-style beauty made by excessive plastic surgery.

Influence of fossil-fuel power plant emissions on the surface fine particulate matter in the Seoul Capital Area, South Korea.

The South Korean government plans to reduce region-wide annual PM2.5 (particulate matter with an aerodynamic diameter ≤2.5 μm) concentrations in the Seoul Capital Area (SCA) from 2010 levels of 27 µg/m(3) to 20 µg/m(3) by 2024. At the same time, it is inevitable that emissions from fossil-fuel power plants will continue to increase if electricity generation expands and the generation portfolio remains the same in the future. To estimate incremental PM2.5 contributions due to projected electricity generation growth in South Korea, we utilized an ensemble forecasting member of the Integrated Multidimensional Air Quality System for Korea based on the Community Multi-scale Air Quality model. We performed sensitivity runs with across-the-board emission reductions for all fossil-fuel power plants in South Korea to estimate the contribution of PM2.5 from domestic fossil-fuel power plants. We estimated that fossil-fuel power plants are responsible for 2.4% of the annual PM2.5 national ambient air quality standard in the SCA as of 2010. Based on the electricity generation and the annual contribution of fossil-fuel power plants in 2010, we estimated that annual PM2.5 concentrations may increase by 0.2 µg/m(3) per 100 TWhr due to additional electricity generation. With currently available information on future electricity demands, we estimated that the total future contribution of fossil-fuel power plants would be 0.87 µg/m(3), which is 12.4% of the target reduction amount of the annual PM2.5 concentration by 2024. We also approximated that the number of premature deaths caused by existing fossil-fuel power plants would be 736 in 2024. Since the proximity of power plants to the SCA and the types of fuel used significantly impact this estimation, further studies are warranted on the impact of physical parameters of plants, such as location and stack height, on PM2.5 concentrations in the SCA due to each precursor.

2004-12-01

Full Text Available Establishing new SEZs, along with improving foreign relationships, is treated as the most important policy measure for opening the North Korean economy. Recently, North Korea has shown its interest in promoting two new SEZs, the Gaeseong industrial park and the Shinuiju special administrative region. Thanks to their locational merits, Gaeseong and Shinuiju have the potential to develop into thriving SEZs through subregional economic cooperation with bordering areas. Although the path toward success for North Korea's new SEZs is full of hurdles, it would result in a major boost to the country's economic rehabilitation and create a spillover effect for the rest of North Korea. In this context, this article examines the issues regarding North Korea's new special economic zones. It presents the recent progress and institutional arrangements of the Shinuiju SEZ and Gaeseong industrial park, while also exploring their potential to facilitate North Korea's economic rehabilitation and inter-Korean cooperation. This article also endeavors to address major problems that North Korea needs to resolve in order to activate its new SEZs.

Full Text Available The Okchon black shale, which is part of the Guryongsan Formation or the Changri Formation of Cambro-Ordovician age in Korea provides a typical example of natural geological materials enriched with potentially toxic elements such as U, V, Mo, As, Se, Cd, and Zn. In this study, the Dukpyung and the Chubu areas were selected to investigate the migration and enrichment of As and other toxic elements in soils and crop plants in areas covered with black shale. Rock and soil samples digested in 4-acid solution (HCl+HNO3+HF+HClO4 were analyzed for As and other heavy metals by ICP-AES and ICP-MS, and plant samples by INAA. Mean concentration of As in Okchon black shale is higher than those of both world average values of shale and black shale. Especially high concentration of 23.2 mg As kg-1 is found in black shale from the Dukpyung area. Mean concentration of As is highly elevated in agricultural soils from the Dukpyung (28.2 mg kg-1 and the Chubu areas (32.6 mg kg-1. As is highly elevated in rice leaves from the Dukpyung (1.14 mg kg-1 and the Chubu areas (1.35 mg kg-1. The biological absorption coefficient (BAC of As in plant species decreases in the order of rice leaves > corn leaves > red pepper = soybean leaves = sesame leaves > corn stalks > corn grains. This indicates that leafy plants tend to accumulate As from soil to a greater degree than cereal products such as grains.

A study on seismic hazard level in Korea has been performed and the main results of the study are summarized as follows: 1. Historians suggest that the quality of historical earthquake data may be accurate in some degree and the data should be used in seismic risk analysis. 2. The historical damage events are conformed in historical literatures and their intensities are re-evaluated by joint researchers. The maximum MM intensity of them is VIII evaluated for 17 events. 3. The relation of earthquakes to surface fault is not clear. It seems resonable to related them to tectonic provinces. 4. Statistical seismic risk analysis shows that the acceleration expected within 50O year return period is less than 0.25G when only instrumental earthquakes are used and less than 0.10G if all of instrumental and historical earthquakes are used. The acceleration in Western Coast and Kyungsang area is higher than the other regions in Korea. 5. The maximum horizontal acceleration determined by conservative method is 0.26G when historical earthquake data are used and less than 0.20G if only instrumental earthquakes are used. The return period of 0.26G is 240 years in Kyungsang province and longer in other provinces. (Author)

This article is based on an embedded case study of selected older people's self-help groups in urban South Korea, which aim to assist community-dwelling older adults, particularly poor and marginalized women, to age in their community and remain active and contributing members. The study highlights the importance of the role and capacity of nongovernmental organizations (NGOs) as partner organizations. Implications are important for other aging societies, particularly in Asia, where older women have been often confined by patriarchal oppression.

Historical changes and recent energy saving potential of residential heating in Korea

International Nuclear Information System (INIS)

Yeo, M.-S.; Yang, I.-H.; Kim, K.-W.

2003-01-01

The residential heating method in Korea underwent various phases of development to reach the current system. The first phase was the traditional Ondol (the traditional under-floor heating system in Korea), where the floor was heated by the circulation of hot gas produced by a fire furnace (before the 1950s). The second phase involved the use of the modified anthracite coal Ondol, for which the fire furnace was modified for briquette use (from the early 1950s to the late 1970s). The third phase involved the use of hot water radiant floor heating with embedded tubes (from the late 1970s). This paper presents insights into the problem of current residential heating in Korea and the general aspects of heating energy savings by tracing the history of residential heating in Korea and analyzing related data. The results show that modern apartment buildings with hot water radiant floor heating (the third phase) yield less heat loss due to the tighter envelope, but also yield higher energy consumption than the traditional Ondol heating housing (the first phase). Because of an inefficient system and lack of thermal insulation of the traditional Ondol heating housing, Ondol heating was used to heat occupants sitting directly on the floor, keeping lower room temperature and higher floor surface temperature. So the range of comfortable floor temperature for Korean people is higher and this unique comfort sense is related to energy consumption in modern apartment housing. As a result, several energy saving methods were found such as reducing the total floor heating area or zoning the floor area, receiving continuous heat supply, and installing a delicate control system and metering devices.

In Korea, nuclear power will be continuously needed to meet the trend of steady increase in electricity demand. But in relation to the further development of nuclear energy, there are still many uncertainties to be solved such as power demand forecast, site availability, thermal energy utilization and technology enhancement for economic and safety. To cope with those uncertainties effectively and to proceed the nuclear projects uninterruptedly, KEPCO decided to initiate two research project. i. e., one is 'the outlook and developmental strategy of nuclear energy for the early 21st century in the R. O. K' and the other is 'the feasibility study on the advanced reactors in Korea. Prospects of nuclear energy in Korea was overviewed and recommendations from the industry were introduced. It is strong opinion of Korea nuclear industry that nuclear policy should be changed from the support policy to the target management policy. In the point of reactor strategy, the life of light water reactor technology might be longer than expected before in Korea and it is emphasized that good maintenance of light water reactor technology and smooth transition program to the advanced technologies should be carefully considered. There are differences in the opinions between preferences to the evolutionary and/or passive, inherently safe reactors but, in the long-term point of view, it is judged to be desirable to have alternatives

Relative Importance of Human Resource Practices on Affective Commitment and Turnover Intention in South Korea and United States

Directory of Open Access Journals (Sweden)

Jaeyoon Lee

2018-05-01

Full Text Available The main purpose of this study was to investigate the impact of perceived HR practices on affective commitment and turnover intention. This study explored which HR practices were relatively more important in predicting affective commitment and turnover intention. A total of 302 employees from the United States and 317 from South Korea completed the same questionnaires for assessing the aforementioned relationships. The results illustrated that among perceived HR practices, internal mobility had the most significant association with turnover intention in both the United States and South Korea. While internal mobility was a stronger predictor of affective commitment for the United States sample, training was the most important variable for predicting affective commitment in South Korea. The second purpose of the study was to examine whether individuals’ positive affect influences the relationship between perceived HR practices and affective commitment and turnover intention. In the United States, positive affect moderated the relationship between perceived HR practices and affective commitment and turnover intention such that the relationships were stronger for individuals reporting high positive affect relative to those reporting low positive affect. However, these relationships were not significant in South Korea. We discuss the implications of these results, study limitations, and practical suggestions for future research.

Post-Fire Restoration Plan for Sustainable Forest Management in South Korea

Directory of Open Access Journals (Sweden)

Soung-Ryoul Ryu

2017-05-01

Full Text Available This review was to determine a standard post-fire restoration strategy for use in South Korea according to the magnitude of the damage and the condition of the affected site. The government has strongly enforced reforestation in deforested areas as well as fire prevention and suppression since the 1960s. These efforts have successfully recovered dense even-aged forests over the last five decades. However, high fuel loading and the homogeneous structure have made forests vulnerable to large fires. In recent years, large forest fires have occurred in the eastern coastal region of Korea. Forest fires can significantly influence the economic and social activities of the residents of such affected forest regions. Burned areas may require urgent and long-term restoration strategies, depending on the condition of the affected site. Erosion control is the most important component of an urgent restoration and should be completed before a rainy season to prevent secondary damage such as landslides and sediment runoff in burned areas. Long-term restoration is necessary to renew forest functions such as timber production, water conservation, ecosystem conservation, and recreation for residents. Sound restoration for burned areas is critical for restoring healthy ecological functions of forests and providing economic incentives to local residents.

2017-12-01

Correlation between the frequency of summer tropical cyclones (TCs) affecting Korea and the East Asian summer monsoon index (EASMI) was analyzed over the last 37 years. A clear positive correlation existed between the two variables, and this high positive correlation remained unchanged even when excluding El Niño-Southern Oscillation (ENSO) years. To investigate the causes of the positive correlation between the two variables in non-ENSO years, after the 8 years with the highest EASMI (high EASMI years) and the 8 years with the lowest EASMI (low EASMI years) were selected, and the average difference between the two phases was analyzed. In high EASMI years, in the difference between the two phases regarding 850 and 500 hPa streamline, anomalous cyclones were reinforced in the tropical and subtropical western North Pacific, while anomalous anticyclones were reinforced in mid-latitude East Asian areas. Due to these two anomalous pressure systems, anomalous southeasterlies developed near Korea, with these anomalous southeasterlies playing the role of anomalous steering flows making the TCs head toward areas near Korea. In addition, a monsoon trough strengthened more eastward, and TCs in high EASMI years occurred more in east ward over the western North Pacific.

2015-01-01

Despite the fact that scientific and political consideration for ecosystem services has dramatically increased over the past decade, few studies have focused on marine and coastal ecosystem services for conservation strategies. We used an ecosystem services approach to assess spatial distributions of habitat risks and four ecosystem services (coastal protection, carbon storage, recreation, and aesthetic quality), and explored the tradeoffs among them in coastal areas of South Korea. Additionally, we analyzed how the social and ecological characteristics in coastal areas interact with conservation and development policies by using this approach. We found strong negative associations between the habitat risks and ecosystem services (aquaculture, carbon storage, recreation, and aesthetic quality) across the coastal counties. Our results showed that the intensity of the habitat risks and the provision of ecosystem services were significantly different between reclamation-dominated and conservation-dominated counties, except for coastal vulnerability. A generalized linear model suggested that reclamation projects were dependent on economic efficiency, whereas demographic pressures and habitat conditions influenced the designation of protected areas at a county level. The ecosystem services approach provided guidelines to achieve both sustainable development and environment conservation. By using the approach, we can select the priority areas for developments while we can minimize the degradation of biodiversity and ecosystem services. As cultural ecosystem services are evenly distributed throughout coastal areas of South Korea, decision makers may employ them to improve the conditions of coastal wetlands outside of protected areas.

Cho, Jungwoo; You, Myoungsoon; Yoon, Yoonjin

2017-01-01

In highly urbanized area where traffic condition fluctuates constantly, transportation infrastructure is one of the major contributing factors to Emergency Medical Service (EMS) availability and patient outcome. In this paper, we assess the impact of traffic fluctuation to the EMS first response availability in urban area, by evaluating the k-minute coverage under 21 traffic scenarios. The set of traffic scenarios represents the time-of-day and day-of-week effects, and is generated by combining road link speed information from multiple historical speed databases. In addition to the k-minute area coverage calculation, the k-minute population coverage is also evaluated for every 100m by 100m grid that partitions the case study area of Seoul, South Korea. In the baseline case of traveling at the speed limit, both the area and population coverage reached nearly 100% when compared to the five-minute travel time national target. Employing the proposed LoST (Loss of Serviceability due to Traffic) index, which measures coverage reduction in percentage compared to the baseline case, we find that the citywide average LoST for area and population coverage are similar at 34.2% and 33.8%. However, district-wise analysis reveals that such reduction varies significantly by district, and the magnitude of area and population coverage reduction is not always proportional. We conclude that the effect of traffic variation is significant to successful urban EMS first response performance, and regional variation is evident among local districts. Complexity in the urban environment requires a more adaptive approach in public health resource management and EMS performance target determination.

The aim of this study was to differentiate between homicides committed by multiple offenders and homicides committed by lone offenders. Using data on homicide incidents that occurred in South Korea between 1985 and 2008, we compared 134 homicides committed by multiple offenders, with 369 homicides committed by lone offenders. A greater proportion of homicides committed by multiple offenders involved injuries to the victim's head compared to homicides by lone offenders. Homicides committed by multiple offenders were more likely to involve blunt instruments and ligatures, whereas homicides by lone offenders were more likely to involve sharp instruments. In addition, a majority of the homicides committed by multiple offenders were planned. The results of this study have practical implications for homicide investigations, as well as theoretical implications for homicide research on the difference in offense behaviors based on the number of offenders. © 2018 American Academy of Forensic Sciences.

Before addressing the issue of public and utility acceptance of nuclear power in Korea, let me briefly explain the Korean nuclear power program and development plan for a passively safe nuclear power plant in Korea. At present, there are eight PWRs and one CANDU in operation; two PWRs are under construction, and contract negotiations are underway for one more CANDU and two more PWRs, which are scheduled to be completed by 1997,1998 and 1999, respectively. According to a recent forecast for electricity demand in Korea, about fifty additional nuclear power plants with a generating capacity of 1000MWe are required by the year 2030. Until around 2006, Korean standardized nuclear power plants with evolutionary features such as those in the ALWR program are to be built, and a new type of nuclear power plant with passive safety features is expected to be constructed after 2006. The Korean government is making a serious effort to increase public understanding of the safety of nuclear power plants and radioactive waste storage and disposal. In addition, the Korean government has recently introduced a program of benefits for residents near nuclear power plants. By this program, common facilities such as community centers and new roads are constructed, and scholarships are given to the local students. Nuclear power is accepted positively by the utility and reasonably well by the public in Korea.

Since the first nuclear power plant in Korea, Kori unit no.1, was started in commercial service in 1978, 20 units including Kori unit no.1 have been operated and maintained until now in Korea. Recently several units were started to be constructed and also, additionally more than 4 units were planned to be constructed in the near future. The importance of nuclear containments has been always one of the hottest issues for the safety and protection of nuclear power plants until now. At the beginning of nuclear power plants construction in Korea, several typed nuclear containment systems were adopted. For those reasons, various codes, standards, and inspection technologies are applied to nuclear containment systems differently. In this study, the status of inservice inspection performed for the safety and maintenance of nuclear containments in Korea was researched. Overall nuclear containment systems and inspections performed up to recently in Korea including trends, inspection items, periods, and regulations were described briefly. (author)

Ingestion of pesticides (mainly paraquat) accounted for one-fifth of suicides in South Korea in 2006-10. We investigated the effect on suicide mortality of regulatory action, culminating in a ban on paraquat in South Korea in 2011-12. We calculated age-standardized method-specific suicide mortality rates among people aged ≥15 in South Korea (1983-2013) using registered death data. Negative binomial regression was used to estimate changes in the rate and number of pesticide suicides in 2013, compared with those expected based on previous trends (2003-11). Pesticide suicide mortality halved from 5.26 to 2.67 per 100 000 population between 2011 and 2013. Compared with the number expected based on previous trends, the regulations were followed by an estimated 847 [95% confidence interval (CI) -1180 to -533] fewer pesticide suicides, a 37% reduction in rates (rate ratio = 0.63, 95% CI 0.55 to 0.73) in 2013. The decline in pesticide suicides after the regulations was seen in all age/sex/geographical groups. The absolute reduction in the number of suicides was greatest among men, the elderly and in rural areas. The reduction in pesticide suicides contributed to 56% of the decline in overall suicides that occurred between 2011 and 2013. There was no impact of the regulations on crop yield. The regulation of paraquat in South Korea in 2011-12 was associated with a reduction in pesticide suicide. Further legislative interventions to prevent the easy availability of highly lethal suicide methods are recommended for reducing the number of suicides worldwide. © The Author 2015; all rights reserved.

1993-03-01

The Republic of Korea has accomplished dramatic economic growth over the past three decades; demand for electricity has rapidly grown more than 15% per year. Since the first nuclear power plant, Kori-1 [587 MWe, pressurized water reactor (PWR)], went into commercial operation in 1978, the nuclear power program has continuously expanded and played a key role in meeting the national electricity demand. Nowadays, Korea has nine nuclear power plants [eight PWRs and one Canadian natural uranium reactor (CANDU)] in operation with total generating capacity of 7,616 MWe. The nuclear share of total electrical capacity is about 36%; however, about 50% of actual electricity production is provided by these nine nuclear power plants. In addition, two PWRs are under construction, five units (three CANDUs and two PWRs) are under design, and three more CANDUs and eight more PWRs are planned to be completed by 2006. With this ambitious nuclear program, the total nuclear generating capacity will reach about 23,000 MWe and the nuclear share will be about 40% of the total generating capacity in the year 2006. In order to expand the nuclear power program this ambitiously, enormous amounts of work still have to be done. One major area is radioactive waste management. This paper reviews the status of low-level radioactive waste management in Korea. First, the current and future generation of low-level radioactive wastes are estimated. Also included are the status and plan for the construction of a repository for low-level radioactive wastes, which is one of the hot issues in Korea. Then, the nuclear regulatory system is briefly mentioned. Finally, the research and development activities for LLW management are briefly discussed.

Long-term trends in observed carbon monoxide (CO) concentrations were analyzed in seven major South Korean cities from 1989 to 2013. Temporal trends were evident on seasonal and annual timescales, as were spatial gradients between the cities. As CO levels in the most polluted cities decreased significantly until the early 2000s, the data were arbitrarily divided into two time periods (I: 1989–2000 and II: 2001–2013) for analysis. The mean CO concentration of period II was about 50% lower than that of period I. Long-term trends of annual mean CO concentrations, examined using the Mann–Kendall (MK) method, confirm a consistent reduction in CO levels from 1989 to 2000 (period I). The abrupt reduction in CO levels was attributed to a combination of technological improvements and government administrative/regulatory initiatives (e.g., emission mitigation strategies and a gradual shift in the fuel/energy consumption mix away from coal and oil to natural gas and nuclear power). - Highlights: • As one of the criteria pollutants, CO has been extensively studied worldwide. • The concentration of CO in ambient air should be reduced to a more manageable level. • The spatiotemporal characteristics of CO in Korea are analyzed for 1989–2013. • Our efforts will help develop systematic strategies to reduce CO emissions. - The efficacy of CO mitigation strategies adopted throughout Korea is highlighted along with the limitations faced to improving air quality due to cross-boundary pollution transport.

The population of Korea is expected to increase by another 1/4 of the current population by the year 2000 if the government family planning program is successful. Aggravating Korea's demographic situation is the worldwide phenomenon of urban congestion. According to official statistics, Seoul's population increased from only 1 million in 1953 to 8.5 million in 1980, the latest year for which figures are available. While Seoul's population alone accounts for 22.3% of the total population, that of the greater Seoul area comprises 13,542,000 people or 35.5% of Korea's population. Most of the country's best institutions of higher learning are concentrated in Seoul, and in 1979 Seoul accounted for nearly half (47.7%) of the nation's college and graduate students. Seoul is also the center of the country's political, economic and cultural life and provides better employment opportunities than elsewhere in the country. The exodus of young people from rural areas and the growing census figures have triggered fears that the subsequently reduced agricultural productivity would result in a food supply crisis. In an attempt to remedy the demographic disparity between urban and rural areas, the government initiated a 10-year program in 1982 to promote jobs and improve medicare and the educational system in provincial cities. The plan encourages the establishment of factories and other auxiliary facilities outside the Seoul area that are necessary to support the 1988 Seoul Olympics. The program's success remains in question as it requires consistent, determined, and well coordinated efforts on the part of policy makers to curb the historical trend which has been gaining momentum over the past 100 years. 2 approaches have been adopted in the government's efforts to integrate population dynamics into the development process, overseas migration, and planned parenthood. Despite the 1981 liberalization of overseas travel for Koreans, Korean migration overseas is not expected to grow

A Policy study on cooperation for the development of underground resources in North Korea

Energy Technology Data Exchange (ETDEWEB)

Hwang, Jung Nam [Korea Energy Economics Institute, Euiwang (Korea)

1999-03-01

For the smooth promotion of joint development program of underground resources in North Korea, it requires a domestic legal authority applicable when a private company begins the development program of underground resources in North Korea. It is recommended that the supply of initial fund of resources development program in North Korea will utilize the supply method of existing resources development subsidizing fund instead of establishing new fund. In the case of enlarging its program by minerals, it is desirable to support it by creating the South-North resources development cooperation fund for a certain period to attract voluntary participation of the private sector. In this study, minerals able to develop among natural minerals in North Korea were classified and presented by grouping according to the higher order. Also, a plan for institutionalizing this was sought by connecting a development program by types of minerals for the smooth operation of South-North resources development cooperation program. Considering types of minerals, area, and the size and cost of development, it should be operated step by step, but for programs realizable at once, it should be started in its early stage. It is recommended to review a step by step plan for mineral resources development in North Korea continuously in connection with other economic cooperation sector such as the manufacturing industry.

The major objective of the project is to hold Korea-S. Africa joint nuclear or workshop and establish a network of nuclear experts between the two countries. In addition, identification of the collaboration items is another objective of this project. the outcome of this program would be a cornerstone for the nuclear collaboration between Korea and S. Africa. African countries is usually very abundant in the natural resources and developed countries are trying to improve relationships with African countries to secure the natural resources, S. Africa is also very rich with some resources including uranium. Therefore, Korea depending on foreign resources needs to improve the relationship with S. Africa form the viewpoint of securing natural resources. S. Africa has two PWR-type nuclear power plants and is planning to deploy more PWRs to increase the nuclear capacity. In addition, S. Africa is a leading country in developing the PBMR, which is a type of Generation-IV VHTR (very high temperature reactor). In Korea, the VHTR technologies are also under development for the nuclear hydrogen. Although Korea has its own PWR brand, it is not well known to S. Africa. The focal point program would lay a cornerstone for mutually beneficial nuclear collaborations between two countries

2008-01-01

Recent agreements between the Democratic People's Republic of Korea (DPRK) and the other countries involved in the six-party talks on the future of the DPRK's nuclear weapons program have focused attention on the North Korean energy sector, and, specifically, what the international community can or should do to assist the DPRK in energy sector redevelopment. During two visits to North Korea in 1998 and 2000, a team of American and North Korean researchers conducted a unique rural energy use survey in a flood-affected rural village in the DPRK-the farming village of Unhari. The information gathered during the survey has important implications on how to properly approach the ongoing rural energy crisis in the DPRK, and, more broadly, to provide overall energy sector assistance. The results of the Unhari survey are described briefly, followed by suggestions of internal policy and legal reforms, approaches to international cooperation, key and attractive energy sector technologies and processes for energy sector redevelopment in the DPRK

Development of an Integrated Natural Barrier Database System for Site Evaluation of a Deep Geologic Repository in Korea - 13527

International Nuclear Information System (INIS)

Jung, Haeryong; Lee, Eunyong; Jeong, YiYeong; Lee, Jeong-Hwan

2013-01-01

Korea Radioactive-waste Management Corporation (KRMC) established in 2009 has started a new project to collect information on long-term stability of deep geological environments on the Korean Peninsula. The information has been built up in the integrated natural barrier database system available on web (www.deepgeodisposal.kr). The database system also includes socially and economically important information, such as land use, mining area, natural conservation area, population density, and industrial complex, because some of this information is used as exclusionary criteria during the site selection process for a deep geological repository for safe and secure containment and isolation of spent nuclear fuel and other long-lived radioactive waste in Korea. Although the official site selection process has not been started yet in Korea, current integrated natural barrier database system and socio-economic database is believed that the database system will be effectively utilized to narrow down the number of sites where future investigation is most promising in the site selection process for a deep geological repository and to enhance public acceptance by providing readily-available relevant scientific information on deep geological environments in Korea.

2001-01-01

The purpose of this study is to compare the difference in health status between South Koreans and North Koreans and to identify factors responsible for the remarkable improvements in the health status of South Koreans. In order to examine the causes of the difference in health level, the health indices and their determinants of two Koreas were analyzed in time order. As of the year 2000, the average life expectancy at birth is 71.0 years for men and 78.6 years for women in South Korea, which is longer than that of North Korea by 8.1 for men and 11.2 for women. Infant mortality rate in 1998 was 9.0 per 1,000 live births in South Korea and 54.0 in North Korea. Since being liberated from Japanese ruling in 1945, South Korea has achieved remarkable economic growth under democracy and a market economy system. On the other hand, North Korea has maintained a socialistic system. North Korea has suffered from economic crisis since the 1990s. From this point it could be said that economic status is the major factor for the differences in health level between the two Koreas. Economic status not only directly influences health level but also indirectly affects it through influences on nutrition, hygiene, health resources, and other intervening factors. The South Korean government has concentrated its limited resources on public health activities such as tuberculosis control, family planning (FP), and maternal and child health (MCH) programmes whereas the private sector has taken charge of constructing the health delivery system including health facilities and human resources. In order to solve the problem, which might occur in the private-oriented medical care system, the South Korean government has introduced the national health insurance programme and enforced regulation policies. Many developing countries which are suffering from poverty and disease, can learn from the experience of Korea that had suffered from similar problems up to the early 1970s.

Few controlled studies have examined social class as a risk factor for suicide in Korea. The objective of the present study was to investigate the effects of social class on suicide risk in Korea. A case-control design was constructed from cause-of-death statistics for the period 1999 to 2001, in Korea, as published by the Korean National Statistical Office. The cases were defined as people aged between 20 and 64 who died by suicide, while the controls were defined as those who died of natural causes in the same age groups. The proportions and odds ratios for suicide were higher in young people than in elderly people, and higher for divorced subjects than for cohabitants. They were also higher for residents of rural areas, as opposed to residents of Seoul and other metropolitan areas, and for people in social classes III and IV, than they were for those in social class I. To control the variables that influence risk of suicide, such as age, marital status and area of residence, we used multiple logistic regression. Compared with class I, risk of suicide was higher in social classes III and IV, in both sexes. The principal conclusion of this study is that, regardless of sex, lower social class constitutes a high risk for suicide in Korea, even after controlling for variables such as age, marital status and area of residence. We conclude that a well-controlled and balanced social welfare system could reduce suicide risk, especially among people in lower social class.

Occupational hearing loss in Korea.

Kim, Kyoo Sang

2010-12-01

In this article, current status of noise exposure in workplaces, trend of workers with noise-induced hearing loss (NIHL), and prevalence of NIHL in workers by industry and job category in Korea were reviewed. In addition, trends of research on the audiological effects such as hearing loss from noise and occupational hearing loss from non-noise in Korea were addressed through reports in industrial audiology. Though noise exposure level has improved, noise still shows the highest rate of cases exceeding exposure limit among workplace hazards. NIHL is the most common occupational disease except work-related disease such as musculoskeletal disorders and cerebrovascular diseases, and NIHL prevalence is thought to be much higher than reported in official publications. Noise affecting hearing comes from various sources such as workplaces, military settings, areas with exposure to high noise, and specific noise sources. There is also occupational hearing loss by non-noise including chemicals such as organic solvents and heavy metals, barotrauma, and trauma due to welding spark. Noise affects daily life through audiological effects such as hearing loss and tinnitus, non-audiological physical effects (e.g., cardiovascular), and psychosocial and behavioral effects. Development of systematic and comprehensive hearing conservation programs for lowering the noise level in workplaces and preventing the NIHL, and preparation of technological, administrative system for its settlement at workplace are urgently needed.

Effect of land use and urbanization on hydrochemistry and contamination of groundwater from Taejon area, Korea

Science.gov (United States)

Jeong, Chan Ho

2001-11-01

Taejon Metropolitan City located in the central part of South Korea has grown and urbanized rapidly. The city depends heavily on groundwater as a water resource. Because of ubiquitous pollution sources, the quality and contamination have become important issues for the urban groundwater supply. This study has investigated the chemical characteristics and the contamination of groundwater in relation to land use. An attempt was made to distinguish anthrophogenic inputs from the influence of natural chemical weathering on the chemical composition of groundwater at Taejon. Groundwater samples collected at 170 locations in the Taejon area show very variable chemical composition of groundwater, e.g. electrical conductance ranges from 65 to 1,290 μS/cm. Most groundwater is weakly acidic and the groundwater chemistry is more influenced by land use and urbanization than by aquifer rock type. Most groundwater from green areas and new town residential districts has low electrical conductance, and is of Ca-HCO3 type, whereas the chemical composition of groundwater from the old downtown and industrial district is shifted towards a Ca-Cl (NO3+SO4) type with high electrical conductance. A number of groundwater samples in the urbanized area are contaminated by high nitrate and chlorine, and exhibit high hardness. The EpCO2, that is the CO2 content of a water sample relative to pure water, was computed to obtain more insight into the origin of CO2 and bicarbonate in the groundwater. The CO2 concentration of groundwater in the urbanized area shows a rough positive relationship with the concentration of major inorganic components. The sources of nitrate, chlorine and excess CO2 in the groundwater are likely to be municipal wastes of unlined landfill sites, leaky latrines and sewage lines. Chemical data of commercial mineral water from other Jurassic granite areas were compared to the chemical composition of the groundwater in the Taejon area. Factor analysis of the chemical data

Kang, Young-Hee

2013-01-01

Using the Korean Labor and Income Panel Study (KLIPS), I investigated the impact of family-friendly policies (FFPs) on job satisfaction and organizational commitment in the private sector of South Korea. Paid leave, childcare leave, and support for housing are positively related to both job satisfaction and organizational commitment. Sick leave is positively related to organizational commitment. However, subsidized family event cost is a marginally significant predictor of job satisfaction and organizational commitment. In addition, the relationships between subsidized childcare cost and employee attitudes were not supported. Implications and suggestions for future research are discussed.

The use of chemical compounds are keep increasing because of their use in manufacturing industry. Chemical accident is growing as the consequence of the chemical use increment. Devastating damages from chemical accidents are far enough to aware people's cautious about the risk of the chemical accident. In South Korea, Gumi Hydrofluoric acid leaking accident triggered the importance of risk management and emphasized the preventing the accident over the damage reducing process after the accident occurs. Gumi accident encouraged the government data base construction relate to the chemical accident. As the result of this effort Chemical Safety-Clearing-house (CSC) have started to record the chemical accident information and damages according to the Harmful Chemical Substance Control Act (HCSC). CSC provide details information about the chemical accidents from 2002 to present. The detail informations are including title of company, address, business type, accident dates, accident types, accident chemical compounds, human damages inside of the chemical industry facilities, human damage outside of the chemical industry facilities, financial damages inside of the chemical industry facilities, and financial damages outside of the chemical industry facilities, environmental damages and response to the chemical accident. Collected the chemical accident history of South Korea from 2002 to 2015 and provide the spatial information to the each accident records based on their address. With the spatial information, compute the data on ArcGIS for the spatial-temporal analysis. The spatial-temporal information of chemical accident is organized by the chemical accident types, damages, and damages on environment and conduct the spatial proximity with local community and environmental receptors.

Introduction of western surgery into Korea is closely related to the introduction of western medicine itself into Korea. In December 4th, 1884 Allen, who came to Korea as a Missionary Doctor of North Presbyterian Church of America, had a chance to treat a patient with severe stab wounds. The patient was a nephew of Queen Myungsung. The patient, Min Young Ik was recovered completely. These happenings led to the establishment of 'Kwangheywon (renamed to Jejoongwon 2 weeks later)', the first westernized hospital in Korea. With the great financial aids from Severance family, Jejoongwon developed into Severance Hospital and Medical School in 1904, and greatly contributed to education of Surgery for Korean medical students. Meanwhile Korean Government established the Medical School and Hospital to train Korean Doctors in 1899. But the original intentions became to be impaired by occupation of Korea by Japan in 1910. As a colony, many Japanese Surgeons came to Korea as professors of Kyungsung Medical College, and gave only few chances for Koreans to become a professor. On the contrary, several surgeons became professors in the private, missionary 'Severance Union Medical College'. After liberation from Japanese occupation in 1945, American medical system was introduced into Korea, and many surgeons had a chance to be trained in America. There was great advancements in the field of surgery, especially of neurosurgery, during a tragic Korean War. With the restoration of economy after the 1960s, surgery in Korea continued to develop toward an independent and consolidated fields of medicine.

Characterizing the influence of transportation infrastructure on Emergency Medical Services (EMS in urban area-A case study of Seoul, South Korea.

Directory of Open Access Journals (Sweden)

Jungwoo Cho

Full Text Available In highly urbanized area where traffic condition fluctuates constantly, transportation infrastructure is one of the major contributing factors to Emergency Medical Service (EMS availability and patient outcome. In this paper, we assess the impact of traffic fluctuation to the EMS first response availability in urban area, by evaluating the k-minute coverage under 21 traffic scenarios. The set of traffic scenarios represents the time-of-day and day-of-week effects, and is generated by combining road link speed information from multiple historical speed databases. In addition to the k-minute area coverage calculation, the k-minute population coverage is also evaluated for every 100m by 100m grid that partitions the case study area of Seoul, South Korea. In the baseline case of traveling at the speed limit, both the area and population coverage reached nearly 100% when compared to the five-minute travel time national target. Employing the proposed LoST (Loss of Serviceability due to Traffic index, which measures coverage reduction in percentage compared to the baseline case, we find that the citywide average LoST for area and population coverage are similar at 34.2% and 33.8%. However, district-wise analysis reveals that such reduction varies significantly by district, and the magnitude of area and population coverage reduction is not always proportional. We conclude that the effect of traffic variation is significant to successful urban EMS first response performance, and regional variation is evident among local districts. Complexity in the urban environment requires a more adaptive approach in public health resource management and EMS performance target determination.

Pinworm infection can occur through contact with contaminated surfaces followed by ingestion or even through inhalation of infective eggs. We have limited information regarding environmental contamination by eggs of Enterobius vermicularis. In order to determine environmental risk factors associated with the rate of E. vermicularis infection, we investigated possible environmental risk factors using a questionnaire from 46 kindergartens in 3 different cities of the southeast area of Korea. In total, using the cellotape anal swab technique, 3,422 children were examined for E. vermicularis infection. We evaluated E. vermicularis egg of books, educational materials, toys, room door handles, dusts of window edges, desks, chairs, tables, and dusts of classrooms. The overall egg-positive rate for E. vermicularis was 6.0%, and the prevalence of enterobiasis in each kindergarten ranged between 0% and 16.9%. We found that 78.9% of egg positive kindergartens were managed by private foundations, which was significantly higher, compared with kindergartens managed by public foundations or the nation. Compared with public or national kindergartens, most private kindergartens were located in residential areas and the number of children in these areas was significantly higher. In conclusion, numbers of children in kindergartens was found to be an environmental risk factor associated with transmission of enterobiasis in Korea.

2016-08-01

Full Text Available Teaching is the act, practice and occupation of a teacher. A teacher is a person who provides education for learners at a school or other place of formal education. The use of teacher in this study is conceptualized to involve all cadres of instructors and teaching team from primary and junior secondary (basic education to senior secondary school. The study examined the areas of job dislikes among teachers with their attendant implications for practice. Using a self-designed and pilot-tested questionnaire, data were collected from a random sample of 3,000 teachers drawn from Lagos, Ogun, and Osun states in the Southwestern geopolitical zone of the country. Specifically, 400 primary and 600 secondary school teachers were drawn from each state. The data were analyzed using simple percentage. It was found that teachers job dislike areas though differ but were within seven areas thus: writing lesson notes (98.5%, marking subject attendance register (98%, disciplining of students in school (90%, and serving as members of committees (78.9%. Other dislike areas include taking students out of school for extramural activities (73.3%, partaking in co-curricular activities in the school (60.3% and examination invigilation (59.1% as areas of common dislike and capable of inhibiting the satisfaction levels of teachers.Furthermore, it was found that differences exist in job dislikes between male and female teachers. The common job dislikes among male were non-interest in marking of scripts and invigilation of examinations whereas the female showed dislikes for serving as committee members and as year tutors.Thus, it was recommended that: some modifications in the operational approaches of classroom teachers (such as deemphasizing lesson note writing and marking of subject attendance register would be required. Teachers should also be financially encouraged via allowances for all other activities outside teaching.

Nuclear energy for the green development of Korea

2009-01-01

The Korean government announced the 'Basic Plan for National Energy towards 2030' last year. The goal of the plan is to achieve energy security, energy efficiency and environmental protection. To achieve green development Korean government plans to increase the portion of nuclear and renewable energy and reduce that of coal and oil energy. According to the plan, Korea will build another 9 units until 2030 and nuclear energy will represent 59% of electricity demands by 2030 which is about 20% higher than last year. Even though environment surrounding the nuclear industry is changing favorably and the government has a plan to increase nuclear energy for green development and optimal energy mix, we have to meet some challenges in the area of safety, waste disposal, public acceptance, and technology development. In this paper, we introduced the history, current status and future prospect of the nuclear industry in Korea, discussed new roles of nuclear energy, and made suggestions how to meet challenges and brace up for the global nuclear renaissance.

GPS-determined Crustal Deformation of South Korea after the 2011 Tohoku-Oki Earthquake: Straining Heterogeneity and Seismicity

Science.gov (United States)

Ree, J. H.; Kim, S.; Yoon, H. S.; Choi, B. K.; Park, P. H.

2017-12-01

The GPS-determined, pre-, co- and post-seismic crustal deformations of the Korean peninsula with respect to the 2011 Tohoku-Oki earthquake (Baek et al., 2012, Terra Nova; Kim et al., 2015, KSCE Jour. of Civil Engineering) are all stretching ones (extensional; horizontal stretching rate larger than horizontal shortening rate). However, focal mechanism solutions of earthquakes indicate that South Korea has been at compressional regime dominated by strike- and reverse-slip faultings. We reevaluated the velocity field of GPS data to see any effect of the Tohoku-Oki earthquake on the Korean crustal deformation and seismicity. To calculate the velocity gradient tensor of GPS sites, we used a gridding method based on least-square collocation (LSC). This LSC method can overcome shortcomings of the segmentation methods including the triangulation method. For example, an undesirable, abrupt change in components of velocity field occurs at segment boundaries in the segmentation methods. It is also known that LSC method is more useful in evaluating deformation patterns in intraplate areas with relatively small displacements. Velocity vectors of South Korea, pointing in general to 113° before the Tohoku-Oki earthquake, instantly changed their direction toward the epicenter (82° on average) during the Tohoku-Oki earthquake, and then gradually returned to the original position about 2 years after the Tohoku-Oki earthquake. Our calculation of velocity gradient tensors after the Tohoku-Oki earthquake shows that the stretching and rotating fields are quite heterogeneous, and that both stretching and shortening areas exist in South Korea. In particular, after the post-seismic relaxation ceased (i.e., from two years after the Tohoku-Oki earthquake), regions with thicker and thinner crusts tend to be shortening and stretching, respectively, in South Korea. Furthermore, the straining rate is larger in the regions with thinner crust. Although there is no meaningful correlation between

So it is important to understand the behavior of debris flow in mountainous terrains, the various methods and models are being presented and developed based on the mathematical concept. The purpose of this study is to investigate the regions that experienced the debris flow due to typhoon called Ewiniar and to perform numerical modeling to design and layout of the Check dam for reducing the damage by the debris flow. For the performance of numerical modeling, on-site measurement of the research area was conducted including: topographic investigation, research on bridges in the downstream, and precision LiDAR 3D scanning for composed basic data of numerical modeling. The numerical simulation of this study was performed using RAMMS (Rapid Mass Movements Simulation) model for the analysis of the debris flow. This model applied to the conditions of the Check dam which was installed in the upstream, midstream, and downstream. Considering the reduction effect of debris flow, the expansion of debris flow, and the influence on the bridges in the downstream, proper location of the Check dam was designated. The result of present numerical model showed that when the Check dam was installed in the downstream section, 50 m above the bridge, the reduction effect of the debris flow was higher compared to when the Check dam were

Full Text Available Anthracnose occurred in bitter gourd grown in Jeongup areas of Korea in 2011. Anthracnose of bitter gourd appeared as dark brown circular spots on naturally infected leaves and fruits. The symptoms of infected leaves and fruits were small brown to dark brown spots and gradually enlarged to larger cylindrical dark brown lesions. The causal fungus of anthracnose isolated from the diseased plants was identified as Colletotrichum gloeosporioides based on the morphological and cultural characteristics and ITS rDNA sequence analysis. All isolates of C. gloeosporioides produced symptoms on the host leaves by artificial inoculation. This is the first report of anthracnose on bitter gourd caused by C. gloeosporioides in Korea.

In Korea currently 4 research ships are under operating in Korea, after the first research vessel equipped shipborne gravity meter was introduced in 1990s. These are Onnuri(launch 1991) of KORDI(Korea Ocean Research & Development Institute), Haeyang2000(launch 1996), Badaro1(launch 2002) of NORI(National Oceanographic Research Institute) and Tamhae2(launch 1997) of KIGAM(Korea Institute of Geoscience and Mineral Resources). Those of research vessel, Haeyang2000 have observed marine gravity data over 150,000 points each year from year 1996 to year 2003. Haeyang2000, about 2,500 tons, is unable to operate onshore so NORI has constructed another 600 tons research ship Badaro1 that has observed marine gravity data onshore since year 2002. Haeyang2000 finished observing marine gravity data offshore within Korean territorial waters until year 2003. Currently Badaro1 is observing marine gravity data onshore. These shipborne gravity data will be very useful and important on geodesy and geophysics research also those data can make a contribution to developing these studies. In this study NORI's shipbrne gravity data from 1996 to 2007 has been processed for fundamental data to compute Korean precise geoid. Marine gravity processing steps as followed. 1. Check the time sequence, latitude and longitude position, etc. of shipborne gravity data 2. Arrangement of the tide level below the pier and meter drift correction of each cruise. 3. Elimination of turning points. 4. The time lag correction. 5. Computation of RV's velocities, Heading angles and the Eötvös correction. 6. Kalman filtering of GPS navigation data using cross-over points. 7. Cross-over correction using least square adjustment. About 2,058,000 points have been processed with NORI's marine gravity data from 1996 to 2007 in this study. The distribution of free-air anomalies was -41.0 mgal to 136.0 mgal(mean 8.90mgal) within Korean territorial waters. The free-air anomalies processed with the marine gravity data are

The impact of regional emissions (e.g., domestic and international) on surface particulate matter (PM) concentrations in the Seoul metropolitan area (SMA), South Korea, and its sensitivities to meteorology and emissions inventories are quantitatively estimated for 2014 using regional air quality modeling systems. Located on the downwind side of strong sources of anthropogenic emissions, South Korea bears the full impact of the regional transport of pollutants and their precursors. However, the impact of foreign emissions sources has not yet been fully documented. We utilized two regional air quality simulation systems: (1) a Weather Research and Forecasting and Community Multi-Scale Air Quality (CMAQ) system and (2) a United Kingdom Met Office Unified Model and CMAQ system. The following combinations of emissions inventories are used: the Intercontinental Chemical Transport Experiment-Phase B, the Inter-comparison Study for Asia 2010, and the National Institute of Environment Research Clean Air Policy Support System. Partial contributions of domestic and foreign emissions are estimated using a brute force approach, adjusting South Korean emissions to 50 %. Results show that foreign emissions contributed ˜ 60 % of SMA surface PM concentration in 2014. Estimated contributions display clear seasonal variation, with foreign emissions having a higher impact during the cold season (fall to spring), reaching ˜ 70 % in March, and making lower contributions in the summer, ˜ 45 % in September. We also found that simulated surface PM concentration is sensitive to meteorology, but estimated contributions are mostly consistent. Regional contributions are also found to be sensitive to the choice of emissions inventories.

For age determination, the single aliquot regenerative-dose (SAR) method was applied to quartz from archaeological materials, using luminescence stimulated by blue light. The quartz samples were extracted from sediment from the hydroponic farm related to rice cultivation in an area of archaeological interest in Buyeo, south of Seoul. The optically stimulated luminescence (OSL) dates obtained offered good agreement with the ages derived by typological assessment and 14 C ages. These ages should contribute significantly to interpretation of the history of rice cultivation in Korea. (author)

The Present Status of Nuclear Medicine in Korea

It is my privilege to give you a brief history on the status of nuclear medicine in Korea. There is nothing much to mention, as the history of the peaceful use of atomic energy is rather short and the RI facilities are limited in the number. It is my sincere hope, however, that you may understand what steps nuclear medicine in the developing countries did take and how it has been developed, seeing the present status of nuclear medicine in Korea, as one of the models. In our country, the peaceful use of atomic energy was actualized since the Law of Atomic Energy had been enacted in March 1959, and the Office of Atomic Energy and the Atomic Energy Research Institute had been established. The Korea Society of Nuclear Medicine was organized in 1961, which i think is one of the older in the Far East area. The Society now held about 170 members and the annual meetings in addition to the quarterly meeting have been held. The 6th general scientific meeting for 1967 is scheduled to be held in 25 November. The society publishes the Korean Journal of Nuclear Medicine twice a year, and the second issue appeared Oct. 1967. The instruments used in nuclear medicine are mostly expensive, therefore, the hospitals equipped with such instruments are inevitably limited in number and the after-service or repair of such instruments are technically not easy. Some of these difficulties, i hope, shall be overcome in the near future.

This study assessed perceived needs for psychological support program for family with victim of child sexual abuse in South Korea. We conducted two separate focus group interviews with five therapists who served child sexual abuse victims and families as well as four mothers of a child sexual abuse victim. Consensual qualitative research analysis revealed four domains: Emotional support for parents, psychoeducation, family therapy, and tailored and flexible service delivery. Core ideas of the four domains were identified. The results were consistent with the family support program contents developed in Western countries and suggested culture-specific contents and culturally sensitive service delivery. Clinical implications for developing family support program in South Korea were discussed.

Objective In respect of the health and safety of the public, universal access to health care is an issue of the greatest importance. The geographic distribution of doctors is one of the important factors contributing to access to health care. The aim of this study is to assess the imbalances in the geographic distribution of neurosurgeons across Korea. Methods Population data was obtained from the National Statistical Office. We classified geographic groups into 7 metropolitan cities, 78 non-metropolitan cities, and 77 rural areas. The number of doctors and neurosurgeons per 100000 populations in each county unit was calculated using the total number of doctors and neurosurgeons at the country level from 2009 to 2015. The density levels of neurosurgeon and doctor were calculated and depicted in maps. Results Between 2009 and 2015, the number of neurosurgeons increased from 2002 to 2557, and the ratio of neurosurgeons per 100000 populations increased from 4.02 to 4.96. The number of neurosurgeons per 100000 populations was highest in metropolitan cities and lowest in rural areas from 2009 to 2015. A comparison of the geographic distribution of neurosurgeons in 2009 and 2015 showed an increase in the regional gap. The neurosurgeon density was affected by country unit characteristics (p=0.000). Conclusion Distribution of neurosurgeons throughout Korea is uneven. Neurosurgeons are being increasingly concentrated in a limited number of metropolitan cities. This phenomenon will need to be accounted when planning for a supply of neurosurgeons, allocation of resources and manpower, and the provision of regional neurosurgical services. PMID:29354242

Full Text Available OBJECTIVES The purpose of this study was to establish a basis for improving or strengthening the preventive strategy against scrub typhus in Korea by comparing and analyzing the difference of prevention behaviors contributing to the occurrence of scrub typhus in Japan and Korea. METHODS The survey was carried out in Jeollabuk-do, which is a high risk and high incidence area, and Fukuoka Prefecture, which is a high risk and low incidence area. The study included 406 Korean farmers and 216 Japanese farmers. Data were collected through face-to-face surveys by interviewers who had completed standardized education. RESULTS Korean farmers have a higher percentage of agricultural working posture that involved contact with weeds than Japanese farmers (p<0.05. The frequency and proportion of weeding were lower in Korean farmers than in Japanese farmers (p<0.05. The level of knowledge about scrub typhus was significantly higher among Korean farmers than among Japanese farmers (p<0.05. Mostly, the behavior of agriculture work was more appropriate for Japanese farmers than for Korean farmers (p<0.05. The total average level of agricultural work was lower in Korea than in Japan, lower in men than women, and lower in part-time farmers than full-time farmers (p<0.05. CONCLUSIONS This study suggests that it is reasonable to develop and provide a program that can improve the level of preventive behavior taking into consideration the characteristics of the subject in order to reduce the incidence of diseases in high-risk areas for scrub typhus.

Impression management has important implications for success at work. This study explores differences in impression management in the East and West by examining the use of self-promotion, ingratiation, and exemplification directed towards three targets: supervisors, peers, and subordinates among 945 company employees from Japan, Korea, and the United States. Our results show that Korean employees used all three strategies most frequently, followed by United States, and then Japanese employees. Japanese and Korean employees used impression management strategies differentially across the three targets, and U.S. employees used impression management equally across targets. This elucidates how cultural trends in hierarchical relationships impact social behavior within the workplace. A follow-up mediation analysis found that relational or labor mobility fully mediated country differences in impression management, suggesting that culture is also reflected in larger social ecological trends in employee's ability and likelihood to change jobs, which also account for impression management strategy usage. Theoretical and practical implications for international business are discussed. This research may be useful in aligning strategies foreign employees might employ for using impression management when in Japan, Korea, and the United States.

The objectives of this study were to survey the radiographic exposure parameters, to measure the patient doses for intraoral dental radiography nationwide, and thus to establish the diagnostic reference levels (DRLs) in intraoral dental X-ray examination in Korea. One hundred two intraoral dental radiographic machines from all regions of South Korea were selected for this study. Radiographic exposure parameters, size of hospital, type of image receptor system, installation duration of machine, and type of dental X-ray machine were documented. Patient entrance doses (PED) and dose-area products (DAP) were measured three times at the end of the exit cone of the X-ray unit with a DAP meter (DIAMENTOR M4-KDK, PTW, Freiburg, Germany) for adult mandibular molar intraoral dental radiography, and corrections were made for room temperature and pressure. Measured PED and DAP were averaged and compared according to the size of hospital, type of image receptor system, installation duration, and type of dental X-ray machine. The mean exposure parameters were 62.6 kVp, 7.9 mA, and 0.5 second for adult mandibular molar intraoral dental radiography. The mean patient dose was 2.11 mGy (PED) and 59.4 mGycm2 (DAP) and the third quartile one 3.07 mGy (PED) and 87.4 mGycm 2 (DAP). Doses at university dental hospitals were lower than those at dental clinics (p 2 (DAP) as the DRLs in adult mandibular molar intraoral dental radiography in Korea.

Current status of liver diseases in Korea: hepatocellular carcinoma.

Primary liver cancer, most of which is hepatocellular carcinoma (HCC), is the third common leading cancer in Korea. During the last two decades, the incidence rate of primary liver cancer has shown a modest decrease, but its mortality rate has slightly increased. The incidence of HCC, according to age, peaks in the late sixth decade in men and in the early seventh decade in women. Hepatitis B virus (HBV) is the most important risk factor, which represents approximately 70% of all HCC, and hepatitis C virus (HCV) and alcohol are the next in order of major risk factors for the development of HCC in Korea. HBV-associated HCC occurs 10 years earlier than HCV-associated HCC due to a more prolonged exposure to HBV, which is vertically transmitted almost from HBsAg-positive mother in HBV-endemic area. National Cancer Control Institute, which was reorganized in 2005, is now working for several national projects such as National Cancer Registration Program, National R&D Program for Cancer Control and National Cancer Screening Program. International collaboration for the clinico-epidemiologic research would be needed to provide the specific measures for managing HCC in diverse etiologic situations. Finally, the mechanisms of hepatitis virus-associated hepatocellular carcinogenesis might be clarified to provide insights into the advanced therapeutic and preventive approaches for HCC in Korea, where the majority of HCC originate from chronic HBV and HCV infections.

In this presentation, Korea's probable maximum precipitations (PMPs) which reflects all of the storm data until recently are calculated, and are compared to the existing PMPs which were calculated at 2000. In Korea, abnormal weather phenomena such as typhoon Rusa and Maemi, and the extreme rainfall event occurred on the east coast of the northern region, that can have a significant impact on the PMP estimation, have frequently happened since 2000. After selecting 240 major storm events from 1973 to 2012, new PMPs are proposed with respect to storm areas (25, 100, 225, 400, 900, 2025, 4900, 10000 and 19600 km2) and storm durations (1, 2, 4, 6, 8, 12, 18, 24, 48 and 72 hours) using the Korea hydro-meteorological method. After estimating future PMPs using future rainfall and dew point temperature information under the Korea Meteorological Administration AR5 RCP 8.5, changes in the PMPs under climate change will be investigated by comparison with present and future PMPs. By separating the changes in PMPs under climate change into the changes caused by rainfall and dew point temperature, the relative impact of future rainfall and dew point temperature information under climate change on future PMPs is quantified. This research was supported by a grant 'Development of the Evaluation Technology for Complex Causes of Inundation Vulnerability and the Response Plans in Coastal Urban Areas for Adaptation to Climate Change' [MPSS-NH-2015-77] from the Natural Hazard Mitigation Research Group, Ministry of Public Safety and Security of Korea.

Corrosion of metallic materials occurs by the reaction with corrosive environment such as atmosphere, marine, soil, urban, high temperature etc. In general, reduction of thickness and cracking and degradation are resulted from corrosion. Corrosion in all industrial facilities and infrastructure causes large economic losses as well as a large number of accidents. Economic loss by corrosion has been reported to be nearly 1-6% of GNP or GDP. In order to reduce corrosion damage of industrial facilities, corrosion map as well as a systematic investigation of the loss of corrosion in each industrial sector is needed. The Corrosion Science Society of Korea in collaboration with 15 universities and institutes has started to survey on the cost of corrosion and corrosion map of Korea since 2005. This work presents the results of the survey on cost of corrosion by Uhlig, Hoar, and input-output methods, and the evaluation of atmospheric corrosion rate of carbon steel, weathering steel, galvanized steel, copper, and aluminum in Korea. The total corrosion cost was estimated in terms of the percentage of the GDP of industry sectors and the total GDP of Korea. According to the result of Input/output method, corrosion cost of Korea was calculated as 2.9% to GDP (2005). Time of wetness was shown to be categories 3 to 4 in all exposure areas. A definite seasonal difference was observed in Korea. In summer and fall, time of wetness was higher than in other seasons. Because of short exposure period (12 months), significant corrosion trends depending upon materials and exposure corrosion environments were not revealed even though increased mass loss and decreased corrosion rate by exposure time

Full Text Available Objectives Pyrethroid pesticides are among the most commonly using insecticides in South Korean households and have been the subject of considerable interest among public health professionals for their potential health effects. The objective of this study is to examine the level of urinary 3-phenoxybenzoic acid (3-PBA among elementary students in South Korea. Methods We conducted a cross-sectional study to evaluate pyrethroid pesticide exposure levels by measuring the urinary metabolites of 3-PBA using a gas chromatography-mass spectrometry method in March 2011. Study participants were 70 Asan-area and Incheon-area elementary students. Results All respondents had values above the detection limit, and the geometric means of 3-PBA in all children were 1.85 μg/L and 1.46 μg/g creatinine. Children with the top 10% urinary levels of 3-PBA were more likely to be girls, under nine years of age, living in a rural area, and living in a residential type apartment. Conclusions South Korean children have a higher concentration of urinary 3-PBA compared with those of other countries. Further research identifying exposure pathways and intervention efforts to reduce environmental pesticide use are needed in South Korea.

The purpose of this study was to explore the factors influencing low birth rate among married women using the National Survey data in Korea. We compared the different influences on women's first and subsequent childbirths. This study was a secondary analysis using the "National Survey on Fertility and Family Health and Welfare", which was a nationally representative survey conducted by the Korea Institute for Health and Social Affairs. We analyzed the data of 3,482 married women (aged between 19 and 39 years) using SPSS 20.0 program for descriptive statistics, t-test, one-way ANOVA, and binary and ordinal logistic regression models. The factors influencing women's first childbirth included perceptions about the value of marriage and children and their education level. The factors influencing their subsequent childbirths included multifaceted variables of maternal age during the first childbirth, residential area, religion, monthly household income, perceptions about the value of marriage and children, and social media. It is necessary to improve women's awareness and positive perceptions about marriage and children in order to increase the birth rate in Korea. Moreover, consistently providing financial and political support for maternal and childcare concerns and using social media to foster more positive attitudes toward having children may enhance birth rates in the future.

PACS industry in Korea

2002-05-01

PACS industry in Korea has been rapidly growing, since government had supported collaborative PACS project between industry and university hospital. In the beginning, PACS industry had focused on developing peripheral PACS solutions, while the Korea PACS society was being formed. A few companies had started developing and installing domestic large-scale full-PACS system for teaching hospitals. Several years later, many hospitals have installed full-PACS system with national policy of reimbursement for PACS exams in November 1999. Both experiences of full-PACS installation and national policy generated tremendous intellectual and technological expertise about PACS at all levels, clinical, hospital management, education, and industrial sectors. There are now more than 20 domestic PACS companies. They have enough experiences which are capable of installing a truly full-PACS system for large-scale teaching hospitals. As an example, a domestic company had installed more than 40 full-PACS systems within 2-3 years. Enough experiences of full-PACS installation in Korea lead PACS industry to start exporting their full-PACS solutions. However, further understanding and timely implementation of continuously evolving international standard and integrated healthcare enterprise concepts may be necessary for international leading of PACS technologies for the future.

DeYoung and Menzie (1999) examined the relations among population, Gross Domestic Product, and mineral consumption (aluminum, cement, copper, and salt) for Japan, Korea, and the United States between 1965 and 1995. They noted the extremely rapid growth of consumption in Korea between 1975 and 1995. Concomitantly, Korea's population growth rate declined. This paper extends that earlier work by examining patterns of consumption of these same commodities in the twenty most populous countries for the period 1970 through 1995. Developed countries, such as France, Germany, Japan, the United Kingdom, and the United States, show patterns of consumption that are stable (cement, copper, and salt) or grow slowly (aluminum). Some developing countries, including China, Thailand, and Turkey, show more rapid growth of consumption, especially of cement, copper, and aluminum. These changing patterns of mineral consumption in developing countries have important implications -- if they continue, there could be major increases in world mineral consumption and major increases in environmental residuals from mineral production and use. If China reaches the level of consumption of copper of developed countries, world consumption could reach levels more than twice that of 1995 (10.5 million tons).

Among 132 soil samples, 65 soil samples (49% were infested with RKN and mean density of RKN was 178 second-stage juveniles per 100 cm³ soil (min. 1 ~ max. 3,947. The frequency of RKN by regional was the highest in Chuncheon with 80%, followed by Cheonan (68%, Nonsan (36%, Buyeo (33% and Yesan (30%. The frequency of RKN by crops was the highest in tomato with 83%, followed by cucumber (61%, strawberry (41%, red pepper (30%, watermelon (26%. To identify the species of RKN, fifteen populations were selected for representative populations. As a phylogenetic analysis of 15 populations, southern root-knot nematode (Meloidogyne incognita, peanut root-knot nematode (M. arenaria and northern root-knot nematode (M. hapla were identified with 47%, 20% and 33% ratio, respectively. In crops, M. incognita, M. arenaria and M. hapla were detected in tomato, M. incognita and M. arenaria were detected in cucumber and watermelon, and M. hapla was detected in strawberry and lettuce. Thus, there should be a continuous management to major species of each crops to prevent dispersal of RKN damages.

The purpose of this study was to categorize surgery-related medical terminologies used in South and North Korea and to compare and analyze discrepancies observed in the terms. This study collected medical terminology used in the North Korean medical book "Surgery" and compared it to medical terminology found in the medical glossary of South Korea. The order of the subtitle was described according to the Instruction to Authors. In total, there were 2,168 individual medical terms, of which only 1,004 words (46.3%) were identical to South Korean medical terms. There were 581 similar terms (26.8%), 265 different terms (12.2%), and 318 terms that are nonexistent in South Korea (14.7%). Less than half of the medical terms used in North Korea match those used in South Korea. It is expected that the prolongation of the current division of South and North Korea will only worsen this discrepancy. Further efforts to bridge the gap through academic exchange between South Korea and North Korea are required in preparation for an era of reunification.

Droughts have been receiving much attention in Korea because severe droughts occurred in recent years, causing significant social, economic and environmental damages in some regions. Residents in agricultural area, most of all, were most damaged by droughts with lack of available water supplies to meet crop water demands. In order to mitigate drought damages, we present a strategy to keep from agricultural droughts by using groundwater to meet water supply as a potential water resource in agricultural areas. In this study, we analyze drought severity and the groundwater potential to mitigate social and environmental damages caused by droughts in Korea. We evaluate drought severity by analyzing spatial and temporal meteorological and hydrological data such as rainfall, water supply and demand. For drought severity, we use effective drought index along with the standardized precipitation index (SPI) and standardized runoff index(SRI). Water deficit during the drought period is also quantified to consider social and environmental impact of droughts. Then we assess the feasibility of using groundwater as a potential source for groundwater impact mitigation. Results show that the agricultural areas are more vulnerable to droughts and use of groundwater as an emergency water resource is feasible in some regions. For a case study, we select Jeong-Sun area located in Kangwon providence having well-developed Karst aquifers and surrounded by mountains. For Jeong-Sun area, we quantify groundwater potential use, design the method of water supply by using groundwater, and assess its economic benefit. Results show that water supply system with groundwater abstraction can be a good strategy when droughts are severe for an emergency water supply in Jeong-Sun area, and groundwater can also be used not only for a dry season water supply resource, but for everyday water supply system. This case study results can further be applicable to some regions with no sufficient water

One of the high capability modern medical equipment is CT scanner and it was introduces to Korea in 1977. The number of CT in Korea has been increased during the last few years and much more expected to be installed. This study was conducted to identify the distribution of CT scanners nation-wide and mutual utilization of CT among hospital, state of utilization by district inhabitant. All operating CT installations in Korea were surveyed in April, 1983, and data concerning the utilization of CT and 10 days actual patient records were obtained from 30 of the total 46 installations. 1. It reveals that 24 of 34 university hospital (71%), owned CT ; 22 of 376 private hospital (6%) in Korea. 2. The 46.4% of the total CT installations were concentrated in Seoul, 6 units in Busan, 4 units in Daegu and 1 to 3 units in 10 other areas. 3. The rate of CT utilization is 19 examination per 100,000 persons per month comparing the total number of unit to whole population, and number of beds, we have an average 1 CT unit per 800,000 inhabitant and 1 CT per 1,048 beds. 4. The average rate of cases referring was 24%, 17.6% were from neighbouring hospitals, while only 4.1% were referred from the linked hospital. In summary, this study reveals the fact of severe regional imbalance in CT scanner distribution, and the urgency of establishment of medical care delivery system in order to maintain geographic access to high cost medical technology. Also, it is pointed out that the social measure requiring mutual use of CT scanner has not successfully operated, and that appropriate modification in the current regulation is called for

The residents living nearby the Sa-sang industrial area (SSIA) continuously were damaged by odorous pollution since 1990s. We determined the concentrations of reduced sulfur compounds (RSCs) [hydrogen sulfide (H2S), methyl mercaptan (CH3SH), dimethyl sulfide (DMS), and dimethyl disulfide (DMDS)], nitrogenous compounds (NCs) [ammonia (NH3) and trimethylamine (TMA)], and carbonyl compounds (CCs) [acetaldehyde and butyraldehyde] by instrumental analysis in the SSIA in Busan, Korea from Jun to Nov, 2011. We determined odor intensity (OI) based on the concentrations of the odorants and resident monitoring records (RMR). The mean concentration of H2S was 10-times higher than NCs, CCs and the other RSC. The contribution from RSCs to the OI was over 50% at all sites excluding the A-5 (chemical production) site. In particular, A-4 (food production) site showed more than 8-times higher the sum of odor activity value (SOAV) than the other sites. This suggested that the A-4 site was the most malodorous area in the SSIA. From the RMR analysis, the annoyance degree (OI ≥ 2) was 51.9% in the industrial area. The 'Rotten' smell arising from the RSCs showed the highest frequency (25.3%) while 'Burned' and 'Other' were more frequent than 'Rotten' in the residential area. The correlation between odor index calculated by instrumental analysis and OI from the RMR was analyzed. The Pearson correlation coefficient (r) of the SOAV was the highest at 0.720 (P food production causes significant annoyance in the SSIA. We also confirm RMR data can be used effectively to evaluate the characteristic of odorants emitted from the SSIA.

3D geospatial information systems should provide efficient spatial analysis tools and able to use all capabilities of the third dimension, and a visualization. Currently, many human activities make steps toward the third dimension like land use, urban and landscape planning, cadastre, environmental monitoring, transportation monitoring, real estate market, military applications, etc. To reflect this trend, the Korean government has been started to construct the 3D geospatial data and service platform. Since the geospatial information was introduced in Korea, the construction of geospatial information (3D geospatial information, digital maps, aerial photographs, ortho photographs, etc.) has been led by the central government. The purpose of this study is to introduce the Korean government-lead 3D geospatial information web-based service for the people who interested in this industry and we would like to introduce not only the present conditions of constructed 3D geospatial data but methodologies and applications of 3D geospatial information. About 15% (about 3,278.74 km2) of the total urban area's 3D geospatial data have been constructed by the national geographic information institute (NGII) of Korea from 2005 to 2012. Especially in six metropolitan cities and Dokdo (island belongs to Korea) on level of detail (LOD) 4 which is photo-realistic textured 3D models including corresponding ortho photographs were constructed in 2012. In this paper, we represented web-based 3D map service system composition and infrastructure and comparison of V-world with Google Earth service will be presented. We also represented Open API based service cases and discussed about the protection of location privacy when we construct 3D indoor building models. In order to prevent an invasion of privacy, we processed image blurring, elimination and camouflage. The importance of public-private cooperation and advanced geospatial information policy is emphasized in Korea. Thus, the progress of

The limited spatial coverage of the air pollution data available from regulatory air quality monitoring networks hampers national-scale epidemiological studies of air pollution. The present study aimed to develop a national-scale exposure prediction model for estimating annual average concentrations of PM 10 and NO 2 at residences in South Korea using regulatory monitoring data for 2010. Using hourly measurements of PM 10 and NO 2 at 277 regulatory monitoring sites, we calculated the annual average concentrations at each site. We also computed 322 geographic variables in order to represent plausible local and regional pollution sources. Using these data, we developed universal kriging models, including three summary predictors estimated by partial least squares (PLS). The model performance was evaluated with fivefold cross-validation. In sensitivity analyses, we compared our approach with two alternative approaches, which added regional interactions and replaced the PLS predictors with up to ten selected variables. Finally, we predicted the annual average concentrations of PM 10 and NO 2 at 83,463 centroids of residential census output areas in South Korea to investigate the population exposure to these pollutants and to compare the exposure levels between monitored and unmonitored areas. The means of the annual average concentrations of PM 10 and NO 2 for 2010, across regulatory monitoring sites in South Korea, were 51.63 μg/m3 (SD = 8.58) and 25.64 ppb (11.05), respectively. The universal kriging exposure prediction models yielded cross-validated R 2 s of 0.45 and 0.82 for PM 10 and NO 2 , respectively. Compared to our model, the two alternative approaches gave consistent or worse performances. Population exposure levels in unmonitored areas were lower than in monitored areas. This is the first study that focused on developing a national-scale point wise exposure prediction approach in South Korea, which will allow national exposure assessments and

The national energy demand is taking a sharp rise on account of the rapid growth of economy in Korea. Unfortunately, Korea has not much choice of alternative energy a promising option for Korea. For instance, eleven nuclear plants are in operation and 7 plants are under construction. Several plants are in planning stage. KAERI has played a major role in the design and operation of the plants in Korea. The spent fuel issue is calling for acute attention nationwide as the number of plants increases. Korea is actively seeking a technical solution to that problem surfacing on the horizon. A preliminary conceptual study on the P and T technology was performed from 1992 to 1996 and the future research directions were derived from that study. Because of the situation Korea is facing with, one of the major technical guidelines is that the P and T technology should be developed in compliance with the NPT. The concept of an accelerator driven subcritical system was found to be the most favorable option according to the conceptual study. KAERI set up an ambitious accelerator driven system development program for next 10 years. Key elementary technologies for a high current accelerator and a subcritical system are scheduled to be developed and experimented for the first five years (1997-2001). For the second five years (2002-2006), the accelerator program is pushed for the completion to parameters of 1 GeV, 20mA with capability to drive a subcritical system. For the subcritical system, a detail design study is to be performed and a small mockup system is to be built for bench scale test purpose

Several epidemiological studies have reported an association between environmental pollution and various health conditions in individuals residing in industrial complexes. To evaluate the effects of pollution from industrial complex on human health, we performed a pooled analysis of environmental epidemiologic monitoring data for residents living near national industrial complexes in Korea. The respiratory and allergic symptoms and the prevalence of acute and chronic diseases, including cancer, were used as the outcome variables for health effects. Multiple logistic regression analysis was used to analyze the relationship between exposure to pollution from industrial complexes and health conditions. After adjusting for age, sex, smoking status, occupational exposure, level of education, and body mass index, the residents near the industrial complexes were found to have more respiratory symptoms, such as cough (odds ratio [OR], 1.18; 95% confidence interval [CI], 1.06 to 1.31) and sputum production (OR, 1.13; 95% CI, 1.03 to 1.24), and symptoms of atopic dermatitis (OR, 1.10; 95% CI, 1.01 to 1.20). Among residents of the industrial complexes, the prevalence of acute eye disorders was approximately 40% higher (OR, 1.39; 95% CI, 1.04 to 1.84) and the prevalence of lung and uterine cancer was 3.45 times and 1.88 times higher, respectively, than those among residents of the control area. This study showed that residents living in the vicinity of industrial complexes have a high risk of acute and chronic diseases including respiratory and allergic conditions. These results can be used as basic objective data for developing health management measures for individuals residing near industrial complexes.

Network medicine considers networks among genes, diseases, and individuals. Networks of mental disorders remain poorly understood, despite their high comorbidity. In this study, a network of mental disorders in Korea was constructed to offer a complementary approach to treatment. Data on the prevalence and morbidity of mental disorders were obtained from the 2006 and 2011 Korean Epidemiologic Catchment Area Study, including 22 psychiatric disorders. Nodes in the network were disease phenotypes identified by Diagnostic and Statistical Manual of Mental Disorders-IV, and the links connected phenotypes showing significant comorbidity. Odds ratios were used to quantify the distance between disease pairs. Network centrality was analyzed with and without weighting of the links between disorders. Degree centrality was correlated with suicidal behaviors and use of mental health services. In 2011 and 2006, degree centrality was highest for major depressive disorder, followed by nicotine dependence and generalized anxiety disorder (2011) or alcohol dependence (2006). Weighted degree centrality was highest in conversion disorder in both years. Therefore, major depressive disorder and nicotine dependence are highly connected to other mental disorders in Korea, indicating their comorbidity and possibility of shared biological mechanisms. The use of networks could enhance the understanding of mental disorders to provide effective mental health services.

In Korea, the potential of groundwater contamination in urban areas is increasing by industrial and domestic waste waters, leakage from oil storage tanks and sewage drains, leachate from municipal landfill sites and so on. Nowadays, chlorinated organic compounds such as trichloroethylene (TCE) and tetrachloroethylene (PCE), which are driving residential area as well as industrial area, are recognized as major hazardous contaminants. As well known, TCE is wisely used industrial activities such as degreasing, metal stripping, chemical manufacturing, pesticide production, coal gasification plants, creosote operation, and also used in automobile service centers, photo shops and laundries as cleaning solvent. Thus, groundwater protection in urban areas is important issue in Korea This study is to understand groundwater quality and contamination characteristics and to estimate risk assessment in Sasang industrial complex, Busan Metropolitan City. Busan Metropolitan City is located on southeastern coast of the Korean peninsula and is the second largest city in South Korea with a population of 3.8 millions. The geology of the study area is composed of andesite, andesitic tuff, biotite granite and alluvium (Kim et al., 1998). However, geology cannot be identified on the surface due to pavement and buildings. According to drill logs in the study area, the geologic section consists in landfill, fine sand, clay, gravelly clay, and biotite granite from the surface. Biotite granite appears 5.5- 6 m depth. Groundwater samples were collected at twenty sites in Sasang industrial complex. The groundwater samples are plotted on Piper's trilinear diagram, which indicates Ca-Cl2 type. The groundwater may be influenced by salt water because Sasang industrial complex is located near the mouse of Nakdong river that flows to the South Sea. The Ca-Cl2 water type may be partly influenced by anthropogenic contamination in the study area, since water type in granite area generally belongs Ca

The prevalence of thyroid cancer has increased very rapidly in Korea. However, there is no published report focusing on thyroid cancer mortality in Korea. In this study, we aimed to evaluate standardized thyroid cancer mortality using data from Statistics Korea (the Statistical Office of Korea). Population and mortality data from 1985 to 2010 were obtained from Statistics Korea. Age-standardized rates of thyroid cancer mortality were calculated according to the standard population of Korea, as well as World Health Organization (WHO) standard population and International Cancer Survival Standard (ICSS) population weights. The crude thyroid cancer mortality rate increased from 0.1 to 0.7 per 100,000 between 1985 and 2010. The pattern was the same for both sexes. The age-standardized mortality rate (ASMR) for thyroid cancer for Korean resident registration population increased from 0.19 to 0.67 between 1985 and 2000. However, it decreased slightly, from 0.67 to 0.55, between 2000 and 2010. When mortality was adjusted using the WHO standard population and ICSS population weights, the ASMR similarly increased until 2000, and then decreased between 2000 and 2010. Thyroid cancer mortality increased until 2000 in Korea. It started to decrease from 2000.

Alcoholism is becoming one of the most serious issues in Korea. The purpose of this review article was to understand the present status of the treatment system for alcoholism in Korea compared to the United States and to suggest its developmental direction in Korea. Current modalities of alcoholism treatment in Korea including withdrawal treatment, pharmacotherapy, and psychosocial treatment are available according to Korean evidence-based treatment guidelines. Benzodiazepines and supportive care including vitamin and nutritional support are mainly used to treat alcohol withdrawal in Korea. Naltrexone and acamprosate are the drugs of first choice to treat chronic alcoholism. Psychosocial treatment methods such as individual psychotherapy, group psychotherapy, family therapy, cognitive behavior therapy, cue exposure therapy, 12-step facilitation therapy, self-help group therapy, and community-based treatment have been carried out to treat chronic alcoholism in Korea. However, current alcohol treatment system in Korea is not integrative compared to that in the United States. To establish the treatment system, it is important to set up an independent governmental administration on alcohol abuse, to secure experts on alcoholism, and to conduct outpatient alcoholism treatment programs and facilities in an open system including some form of continuing care.

After the Korean War (1950-1953), nearly 6.5% of South Korea's population had active tuberculosis (TB). In response, South Korea implemented the National Tuberculosis Program in 1962. From 1965 to 1995, the prevalence of bacteriologically confirmed pulmonary TB in South Korea decreased from 940 to 219 cases per 100,000 population. Astounding economic growth might have contributed to this result; however, TB incidence in South Korea remains the highest among high-income countries. The rate of decrease in TB incidence seems to have slowed over the past 15 years. A demographic shift toward an older population, many of whom have latent TB and various concurrent conditions, is challenging TB control efforts in South Korea. The increasing number of immigrants also plays a part in the prolonged battle against TB. A historical review of TB in South Korea provides an opportunity to understand national TB control efforts that are applicable to other parts of the world.

2005-01-01

An instrumental neutron activation analysis was used to measure the concentrations of about 24 elements associated with airborne particulates (PM10) that were collected in the most polluted urban region of Daejeon city, Korea from 2000 to 2002. Using the measurement data for various elements, both the extent of elemental pollution in the study area and the seasonality in their distribution characteristics were examined. Examinations of their distribution patterns indicated that most elements with crustal origin tend to exhibit seasonal peaks during spring, while most elements with anthropogenic origin tend to exhibit seasonal peaks during fall or winter. In order to explain the factors regulating their mobilization properties, the data were processed by a factor analysis. Results of the factor analysis suggested competing roles of both industrial and natural source processes, despite that the study site is located at a downwind position of the industrial complex. Based on the overall results of this study, it is concluded that the site may be strongly impacted by man-made sources but the general patterns of elemental distributions in the study area inspected over a seasonal scale are quite consistent with those typically observed from natural environment

The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information on human resources, brachytherapy equipment, and suggestions for future directions of brachytherapy policy in Korea. The response rate of the survey was 88.3%. The average number of radiation oncologists per center was 2.3. At the time of survey, 28 centers (36.8%) provided brachytherapy to patients. Among the 28 brachytherapy centers, 15 (53.5%) were located in in the capital Seoul and its surrounding metropolitan areas. All brachytherapy centers had a high-dose rate system using (192)Ir (26 centers) or (60)Co (two centers). Among the 26 centers using (192)Ir sources, 11 treated fewer than 40 patients per year. In the two centers using (60)Co sources, the number of patients per year was 16 and 120, respectively. The most frequently cited difficulties in performing brachytherapy were cost related. A total of 21 centers had a plan to sustain the current brachytherapy system, and four centers noted plans to upgrade their brachytherapy system. Two centers stated that they were considering discontinuation of brachytherapy due to cost burdens of radioisotope source replacement. The present study illustrated the current status of brachytherapy in Korea. Financial difficulties were the major barriers to the practice of brachytherapy.

Reverse brain drain in South Korea: state-led model.

Science.gov (United States)

Yoon, B L

1992-01-01

Korea's reverse brain drain (RBD) has been an organized government effort, rather than a spontaneous social phenomenon, in that various policies and the political support of President Park, Chung-Hee were instrumental in laying the groundwork for its success. Particular features of Korea's RBD policies are the creation of a conducive domestic environment (i.e., government-sponsored strategic R & D institution-building, legal, and administrative reforms), and importantly, the empowerment of returnees (via, i.e., exceptionally good maternal benefits, guarantees of research autonomy). President Park played the cardinal role in empowering repatriates at the expense of his own civil bureaucracy, and his capacity for such patronage derived from Korea's bureaucratic-authoritarian political system. Returning scientists and engineers directly benefitted from this political system as well as Park's personal guardianship. For Park, empowerment of returning "brains" was necessary to accomplish his national industrialization plan, thereby enhancing his political legitimacy in domestic politics. An alliance with the R & D cadre was functionally necessary to successfully consolidate strong presidential power, and politically nonthreatening due to the particular form of "pact of domination" in Korea's power structure. RBD in Korea will continue in the near future given Korea's drive for high technology, and the remarkable expansion of local industrial and educational sectors. Korea's future RBD, however, needs to pay closer attention to the following 4 problems: research autonomy; equality issues; skill-based repatriation of technicians and engineers rather than Ph.Ds; and subsidies to small and medium industry for RBD.

Full Text Available This study investigated metadiscourse in the persuasive essays of fourth graders from both urban and rural communities: 224 students in South Korea and 188 in the US. Each student was asked to write a persuasive essay in his or her native Korean or English in response to a story not previously read or discussed. Analysis with a taxonomy developed by Hyland (2004 indicated significant differences in the metadiscourse by country. In terms of interactive metadiscourse, South Korean students used more sentence-level transitions than U.S. students, who used more frame markers and endophoric markers. With regard to interactional metadiscourse, U.S. students used more hedges, boosters, engagement markers, and self-mentions in their essays. This study also compared the students′ essays by the type of community in which the writers lived. In the US the essays of students in rural communities contained more hedges, whereas those of students in urban areas included significantly more self-mentions. In South Korea, no significant difference was detected in the metadiscourse of students living in rural and urban areas.

Yang, S.-K.; Jung, W.-Y.; Kang, M.-S.

2012-04-01

Jeju Island is a volcanic island located at the southernmost of Korea, and is the heaviest raining area in Korea, but due to its hydrological / geological characteristics different from those of inland areas, most streams are of the dry form, and it relies on groundwater for water resources. As for some streams, however, springwater is discharged at a point near the downstream of the final discharge to maintain the flow of the stream; this has been developed as the source for water supply since the past, but the studies on detail observations and analysis are yet inadequate. This study utilizes the ADCP (Acoustic Doppler Current Profiler) hydrometer to regularly observe the flow amount of base run-off stream, and the water resources of base discharge basin of Jeju Island were analyzed using the SWAT (Soil & Water Assessment Tool) model. The detail water resource analysis study using modeling and site observation with high precision for Jeju Island water resources is expected to become the foundation for efficient usage and security of water resources against future climate changes.

Of the more than 300 octopus species, Octopus minor is one of the most popular and economically important species in Eastern Asia, including Korea, along with O. vulgaris, O. ocellatus, and O. aegina. We developed 19 microsatellite markers from Octopus minor and eight polymorphic markers were developed to analyze the genetic diversity and relationships among four octopus populations from Korea and three from China. The number of alleles per locus varied from 10 to 49, and allelic richness per locus ranged from 2 to 16.4 across all populations. The average allele number among the populations was 11.1, with a minimum of 8.3 and a maximum of 13.6. The mean allelic richness was 8.7 in all populations. The Hardy-Weinberg equilibrium (HWE) test revealed significant deviation in 19 of the 56 single-locus sites, and null alleles were presumed in five of eight loci. The pairwise F ( ST ) values between populations from Korea and China differed significantly in all pairwise comparisons. The genetic distances between the China and Korea samples ranged from 0.161 to 0.454. The genetic distances among the populations from Korea ranged from 0.033 to 0.090, with an average of 0.062; those among populations from China ranged from 0.191 to 0.316, with an average of 0.254. The populations from Korea and China formed clearly separated into clusters via an unweighted pair group method with arithmetic mean dendrogram. Furthermore, a population from muddy flats on the western coast of the Korean Peninsula and one from a rocky area on Jeju Island formed clearly separated subclusters. An assignment test based on the allele distribution discriminated between the Korean and Chinese origins with 96.9 % accuracy.

In 2007 total waste generation rate in Korea was 318,670 ton,day. In general waste generation rate shows rising trend since 2000. Wastes are composed of municipal waste 14.9 % industrial waste 34.1 % and construction waste 51.0 %. Treatment of wastes by recycling was 81.1 % landfill 11.1 % incineration 5.3 % and ocean dumping 2.4 %. National waste energy policies have been influenced by various factors such as environmental problem economy technology level (could be made energy), and so on. Korea has the worlds third dense population density environmental pollution load per unit land area is the highest in OECD countries caused due to the fast development in economy, industrialization and urbanization in recent. Also, land area per person is just 2,072 m 2 . Landfill capacity reaches the upper limit, industrial waste generation is increasing. Searching new-renewable energy is vital to substitute fossil fuel considering its increasing price. Korea is the world's 10th biggest energy consuming country and 97% of energy depends on importing. Korea aims to increases supply of new-renewable energy by 5% until the 2011. In this study, we computed the amount of combustible waste from municipality generated by the multiple regression analysis. The existing technologies for converting waste to energy were surveyed and the technologies under development or utilizing in future were also investigated. Based on the technology utilization, the amount of energy using waste to energy technology could be estimated in future. (author)

South Korea's low fertility raises European-style issues.

Haub, C

1991-10-01

A demographic revolution has taken place in South Korea as evidenced by the marked decline in total fertility rate (TFR) from 6 in 1960 to the 1987 level of 1.6. South Korea holds the record for low fertility among developing countries, with women in South Korea averaging fewer children in their lifetimes than do women in Europe. The 1987 TFR for South Korea was even less than that of Sweden, Norway, and France. Emphasizing high initial rates of contraceptive use, family planning (FP) has been a strong component of South Korea's 5-year plans since 1962. Strong governmental support backed the efforts of a large group of FP workers who provided free contraceptives from private physicians. High discontinuation rates resulted, however, and the abortion rate has soared to equal the number of live births. Albeit a developing nation, South Korea now faces the challenges of below replacement fertility more typical of more developed countries. Current fertility levels indicate population increase to approximately 50 million by 2020, followed by a slow decline. While reducing pressure on limited resources, population decline and demographic aging will also demand allocation of a higher proportion of government funds to medical care, and potentially threaten South Korea's competitiveness in the world labor market. Having effected decreases in population growth and fertility, the government reduced the annual sterilization target in 1986 from 300,000 to 60,000 by 1991, and will increasingly turn to the private sector and national health insurance for service provision to all but the poor. A 2-child family norm may be promoted, FP programs expanded to the unmarried and legislation developed to eliminate the preference for sons. Delivery systems may also be reorganized to encourage continued use of contraceptive methods.

In Korea, there has been a concern on tsumami risks for the Nuclear Power Plants since the 1983 Nihonkai-Chubu earthquake tsunami. The maximum run-up height reached 4 m to north of the Ulchin nuclear power plant site. The east coast of Korea was also attacked by a few meters high tsunami generated by the 1993 Hokkaido Nansei-Oki earthquake. Both source areas of them were in the areas western off Hokkaido to the eastern margin of the Japan Sea, which remains another tsunami potential. Therefore it is necessary to study tsunami risks for coast of Korea by means of geological investigation and numerical simulation. Historical records of earthquake and tsunami in the Japan Sea were re-compiled to evaluate tsunami potential. A database of marine active faults in the Japan Sea was compiled to decide a regional potential of tsunami. Many developed reverse faults are found in the areas western off Hokkaido to the eastern margin of the Japan Sea. The authors have found no historical earthquake in the East China Sea which caused tunami observed at coast of Korea. Therefore five fault models were determined on the basis of the analysis results of historical records and recent research results of fault parameter and tunami. Tsunami heights were estimated by numerical simulation of nonlinear dispersion wave theory. The results of the simulations indicate that the tsunami heights in these cases are less than 0.25 m along the coast of Korea, and the tsunami risk by these assumed faults does not lead to severe impact. It is concluded that tsunami occurred in the areas western off Hokkaido to the eastern margin of the Japan Sea leads the most significant impact to Korea consequently. (author)

1997-06-01

Korea s natural gas demand has increase enormously since 1986. Natural gas demand in Korea will approach to 29 million tonnes by the year 2010, from little over 9 million tonnes in 1996. This rapid expansion of natural gas demand is largely due to regulations for environmental protection by the government as well as consumers preference to natural gas over other sources of energy. Especially industrial use of gas will expand faster than other use of gas, although it will not be as high as that in European and North America countries. To meet the enormous increase in demand, Korean government and Korea Gas Corporation (KOGAS) are undertaking expansion of capacities of natural gas supply facilities, and are seeking diversification of import sources, including participation in major gas projects, to secure the import sources on more reliable grounds.

Full Text Available BackgroundThe prevalence of thyroid cancer has increased very rapidly in Korea. However, there is no published report focusing on thyroid cancer mortality in Korea. In this study, we aimed to evaluate standardized thyroid cancer mortality using data from Statistics Korea (the Statistical Office of Korea.MethodsPopulation and mortality data from 1985 to 2010 were obtained from Statistics Korea. Age-standardized rates of thyroid cancer mortality were calculated according to the standard population of Korea, as well as World Health Organization (WHO standard population and International Cancer Survival Standard (ICSS population weights.ResultsThe crude thyroid cancer mortality rate increased from 0.1 to 0.7 per 100,000 between 1985 and 2010. The pattern was the same for both sexes. The age-standardized mortality rate (ASMR for thyroid cancer for Korean resident registration population increased from 0.19 to 0.67 between 1985 and 2000. However, it decreased slightly, from 0.67 to 0.55, between 2000 and 2010. When mortality was adjusted using the WHO standard population and ICSS population weights, the ASMR similarly increased until 2000, and then decreased between 2000 and 2010.ConclusionThyroid cancer mortality increased until 2000 in Korea. It started to decrease from 2000.

Full Text Available Most previous studies have focused on the association between acute myocardial function (AMI and temperature by gender and age. Recently, however, concern has also arisen about those most susceptible to the effects of temperature according to socioeconomic status (SES. The objective of this study was to determine the effect of heat and cold on hospital admissions for AMI by subpopulations (gender, age, living area, and individual SES in South Korea. The Korea National Health Insurance (KNHI database was used to examine the effect of heat and cold on hospital admissions for AMI during 2004–2012. We analyzed the increase in AMI hospital admissions both above and below a threshold temperature using Poisson generalized additive models (GAMs for hot, cold, and warm weather. The Medicaid group, the lowest SES group, had a significantly higher RR of 1.37 (95% CI: 1.07–1.76 for heat and 1.11 (95% CI: 1.04–1.20 for cold among subgroups, while also showing distinctly higher risk curves than NHI for both hot and cold weather. In additions, females, older age group, and those living in urban areas had higher risks from hot and cold temperatures than males, younger age group, and those living in rural areas.

Full Text Available This paper uses a 53-country 15-industry computable general equilibrium model of trade to analyze the effects of the Korea-China free trade agreement on the Korean economy, the manufacturing sector in particular. The model is based on Yaylaci and Shikher (2014 which uses the Eaton-Kortum methodology to explain intra-industry trade. The model predicts that the Korea-China FTA will increase Korea-China manufacturing trade by 56%, manufacturing employment in Korea by 5.7% and China by 0.55%. The model also predicts significant reallocation of employment across industries with the Food industry in Korea losing jobs and other industries there gaining jobs, with the Medical equipment industry gaining the most. There will be some trade diversion from the ASEAN countries, as well as Japan and the United States.

To investigate the substance use and sexual behavior of adolescents in multicultural families compared with adolescents in Korean families in South Korea. Data from the 2013 Korean Youth Risk Behavior Web-Based Survey collected from 66,591 adolescents aged 12-18 years (mean age 14.89±1.76 years) were analyzed. We classified the adolescents into four groups: those whose father and mother were born in South Korea, those whose father was born in South Korea but whose mother was not, those whose mother was born in South Korea but whose father was not, and those whose father and mother were not born in South Korea. Experiences with alcohol, cigarette, and drug use and sexual relations were investigated. Compared with adolescents whose fathers and mothers were born in Korea, adolescents whose fathers were born in Korea but whose mothers were not were less likely to use alcohol and cigarettes. Adolescents whose mothers were born in Korea but whose fathers were not and adolescents whose fathers and mothers were both born outside Korea were more likely to use cigarettes and drugs and to have sexual relations. These results indicate that adolescents whose fathers were not born in Korea and whose fathers and mothers were both born outside Korea are at greater risk for cigarette and drug use and risky sexual behaviors. For these high risk groups, health education should include dependency prevention program, safety issue, and health screening as well as programs aimed at preventing substance use and sexual activity.

In Korea, there is a pervasive feeling of invincibility to the point that people and organizations do not believe that disasters can strike them. This has impact on the level of preparedness for disasters. This study aims to delve into how Korea has to change its governmental policies/practices with some private partners' efforts to mitigate disaster risks. A case study was utilized as the major methodology by comparing exclusive management with inclusive management. These two approaches have been comparatively analyzed via four variables, namely the central government, the local governments, the incident commander, and other stakeholders. The major finding is that Korea's practices and policies have to evolve from the current exclusive management into future-oriented inclusive management. Moreover, the importance of communication, cooperation, collaboration, and multi-discipline coordination is discussed. Additionally, the problem of reductionism and equal participation among all stakeholders, as well as the resistance from vested interests, are recognized and elaborated for Korea and the international community. - Highlights: • Only a few stakeholders in Korea believe that disaster can happen to anyone.

Sheen, D.; Shin, J.

2008-12-01

The variations of seismic background noise in South Korea have been investigated by means of power spectral analysis. The Korea Institute of Geoscience and Mineral Resources (KIGAM) and the Korea Meteorological Administation (KMA) have national wide seismic networks in South Korea, and, in the end of 2007, there are 30 broadband stations which have been operating for more than a year. In this study, we have estimated the power spectral density of seismic noise for 30 broadband stations from 2005 to 2007. Since we estimate PSDs from a large dataset of continuous waveform in this study, a robust PSD estimate of McNamara and Buland (2004) is used. In the frequency range 1-5 Hz, the diurnal variations of noise are observed at most of stations, which are especially larger at coastal stations and at insular than at inland. Some stations shows daily difference of diurnal variations, which represents that cultural activities contribute to the noise level of a station. The variation of number of triggered stations, however, shows that cultural noise has little influence on the detection capability of seismic network in South Korea. Seasonal variations are observed well in the range 0.1-0.5 Hz, while much less found in the frequency range 1-5 Hz. We observed that strong peaks in the range 0.1-0.5 Hz occur at the summer when Pacific typhoons are close to the Korean Peninsula.

In order to meet the increasing energy demand in Korea, continuous promotion of nuclear power program will be inevitable in the future. However, the use of nuclear energy eventually requires effective and reliable radioactive waste management. For the safe and economical management of radioactive waste, first of all, volume reduction is essentially required and hence the development of related technologies continuously be pursued. A site for overall radioactive waste management has to be secured in Korea. KEPCO-NETEC will improve public understanding by reinforcing PA and will maintain transparency of radioactive waste management. (author). 1 fig

Monitoring of suspended sediment variation using Landsat and MODIS in the Saemangeum coastal area of Korea.

2012-02-01

Suspended sediment concentration (SS) is an important indicator of marine environmental changes due to natural causes such as tides, tidal currents, and river discharges, as well as human activities such as construction in coastal regions. In the Saemangeum area on the west coast of Korea, construction of a huge tidal dyke for land reclamation has strongly influenced the coastal environment. This study used remotely sensed data to analyze the SS changes in coastal waters caused by the dyke construction. Landsat and MODIS satellite images were used for the spatial analysis of finer patterns and for the detailed temporal analysis, respectively. Forty Landsat scenes and 105 monthly composite MODIS images observed during 1985-2010 were employed, and four field campaigns (from 2005 to 2006) were performed to verify the image-derived SS. The results of the satellite data analyses showed that the seawater was clear before the dyke construction, with SS values lower than 20 g/m(3). These values increased continuously as the dyke construction progressed. The maximum SS values appeared just before completion of the fourth dyke. Values decreased to below 5 g/m(3) after dyke construction. These changes indicated tidal current modification. Some eddies and plumes were observed in the images generated from Landsat data. Landsat and MODIS can reveal that coastal water turbidity was greatly reduced after completion of the construction. Copyright © 2011 Elsevier Ltd. All rights reserved.

2016-06-01

Full Text Available Abstract Background This study investigated whether the prevalence, awareness, treatment, and control of hypertension and diabetes differed by residential areas. In addition, the rate of good hypertension or diabetes control was examined separately in men and women, and in urban and rural areas. Methods This study used Korea National Health and Nutrition Examination V (2010–2012 data, a nationwide cross-sectional survey of general South Korean population. Residential areas were categorized into urban and rural areas. To examine differences between the residential areas in terms of prevalence, awareness, treatment, and control of hypertension and diabetes we performed a multivariate logistic regression adjusting for age, body mass index, physical activity, alcohol use, smoking, marital status, monthly income, and educational level. To investigate control of hypertension or diabetes within each residential area, we performed a subgroup analysis in both urban and rural areas. Results The prevalence of hypertension is higher among men in urban areas than among those in rural areas (OR = 0.80; 95 % CI = 0.67–0.96, reference group = urban areas. However, the subgroups did not differ in terms of diabetes prevalence, awareness, treatment, and control. Regardless of both sex and residential area, participants in good control of their hypertension and diabetes were younger. Inequality in good control of hypertension was observed in men who lived in urban (≤Elementary school, OR 0.74, 95 % CI 0.60–0.92 and rural areas (≤Elementary school, OR 0.67, 95 % CI 0.46–0.99. Inequality in health status was found in women who resided in urban areas (≤Elementary school, OR 0.53, 95 % CI 0.37–0.75. Good control of diabetes also showed inequalities in health status for both men (≤Elementary school, OR 0.61, 95 % CI 0.40–0.94; Middle/High school, OR 0.69, 95 % CI 0.49–0.96 and women in urban areas (≤1 million won, OR 0.56, 95�

Zn deficiency may be widespread in Asian countries such as South Korea. However, dietary habits have changed in response to rapid economic growth and globalization. Zn nutrition in South Koreans has therefore been assessed during a period (1969-1998) of unprecedented economic growth. Cross-sectional food consumption data from the Korean National Nutrition Survey Reports (KNNSR) of South Korea at four separate time points (1969, 1978, 1988 and 1998) were used to calculate Zn, Ca and phytate intakes using various food composition tables, databases and literature values. Nutrient values in local foods were cited from their analysed values. Average Zn intake was 5.8, 4.8 and 5.3 mg/d for 1969, 1978 and 1988 respectively, increasing to 7.3 mg/d in 1998 (73 % of the Korean Dietary Reference Intake). The phytate:Zn molar ratio decreased from 21 to 8 during the study period. Dietary Zn depletion due to marked decreases in cereal consumption, particularly barley which has a low Zn bioavailability, was counterbalanced by marked increases in the consumption of meat and fish, which are also Zn-rich foods. Reduced phytate consumption coincident with increased Zn intake suggests that Zn bioavailability also improved, particularly by 1998. Although total Zn intake was not greatly affected over the initial period of economic growth in South Korea (1969-1988), Zn contributions from different food sources changed markedly and both Zn intake and potential bioavailability were improved by 1998. The study may have implications for Zn nutrition in other Asian countries currently experiencing rapid economic growth.

Preliminary Research on the Verification Task of North Korea's Plutonium Declaration

International Nuclear Information System (INIS)

Kim, Hyun Chul; Park, Il Jin

2009-01-01

The denuclearization of North Korea seems challenging. North Korea has recognized itself as a nuclear weapon state by carrying out two nuclear tests while many other nations including South Korea have opposed North Korea's nuclear proliferation. As a result of longstanding negotiations, North Korea provided nearly 19,000 pages of operation history of three Yongbyon nuclear facilities on May 8, 2008 and a 60-page declaration of its nuclear activities and programs on June 26, 2008. However, one should notice that declaration documents are by themselves meaningless without their verification. To completely dismantle North Korea's nuclear programs, the verification task based on its declaration documents should be performed very thoroughly, considering the possibility of the presence of the undeclared nuclear materials and facilities. The verification task of North Korea's nuclear declaration consists of many broad themes to deal with, such as the review of declaration documents, the interview with facility operators, the sampling in the field, the laboratory analysis of the sample, data interpretation, and so on. One of the important themes is to verify North Korea's declared plutonium stockpile by comparing the declaration documents with measurement data which can be obtained from the sampling in the field and laboratory analysis. To prepare for the possible future verification of the declared plutonium stockpile, it is meaningful to give a thought on what data can be compared and what samples need to be taken and analyzed. In this study, we focus on the data to be compared and samples to be taken and analyzed for the plutonium accounting, as a preliminary research. To give a quantitative example, the nuclear material of the most recent North Korea's spent fuel rods discharged from the 5 MWe reactor is analyzed. On June 13, 2009, North Korea declared that more than one-third of the spent fuel rods had been reprocessed

The South Korean nuclear power industry is described in this article. By comparing policy on nuclear technology in North and South Korea, differing political allegiances are highlighted. South Korea, rather than pursuing nuclear weapons capability like North Korea, has worked hard to produce a rapidly expanding nuclear powered electricity supply industry, which is described. Government targets which aim to meet predicted increases in demand for electricity are noted, but the problems of waste management and reprocessing have yet to be solved. (UK)

Hepatitis A virus is one of the most frequent causes of foodborne infection, which is closely associated with sanitary conditions and hygienic practices. The clinical spectrum of acute hepatitis A is wide, ranging from mild case without any noticeable symptoms to severe case with acute liver failure leading to mortality. The severity and outcome are highly correlated with age at infection. In developing countries, most people are infected in early childhood without significant symptom. Ironically, in area where sanitary condition has improved rapidly, adults who do not have immunity for viral hepatitis A (VH-A) in early childhood is accumulating. Adults without immunity are exposed to risks of symptomatic disease and large outbreaks in society. In Korea, where hygiene has improved rapidly, acute hepatitis A is a significant health burden that needs to be managed with nationwide health policy. The incidence of symptomatic VH-A has increased since 2000 and peaked in 2009. Korea has designated hepatitis A as a group 1 nationally notifiable infectious disease in 2001. Since 2001, mandatory surveillance system has been established to detect every single case of acute hepatitis A. Universal, nationwide vaccination program for newborns was introduced in 2015. In this review, we will present the current epidemiologic status of viral hepatitis A, and evaluate the effectiveness of the current nationwide strategies for the control of viral hepatitis A in Korea. Furthermore, we presented some action proposals that can help eliminate viral hepatitis A, which is a significant health burden in Korea.

To evaluate scientific papers published by Korean radiologists in the Science Citation Index Expanded (SCIE) radiology journals, between 1986 and 2010. The Institute for Scientific Information Web of Knowledge-Web of Science (SCIE) database was searched for all articles published by Korean radiologists, in SCIE radiology journals, between 1986 and 2010. We performed the analysis by typing 'Korea' and 'radiol' in the address section and selecting the subject area of 'Radiology, Nuclear Medicine, and Medical Imaging' with the use of the general search function of the software. Analyzed parameters included the total number of publications, document types, journals, and institutions. In addition, we analyzed where Korea ranks, compared to other countries, in terms of the number of published articles. All these data were analyzed according to five time periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. Overall, 4974 papers were published by Korean radiologists, in 99 different SCIE journals, between 1986 and 2010, of which 4237 (85.2%) were article-type papers. Of the total 115395 articles, worldwide, published in radiology journals, Korea's share was 3.7%, with an upward trend over time (p < 0.005). The journal with the highest number of articles was the American Journal of Roentgenology (n 565, 13.3%). The institution which produced the highest number of publications was Seoul National University (n = 932, 22.0%). The number of scientific articles published by Korean radiologists in the SCIE radiology journals has increased significantly between 1986 and 2010. Korea was ranked 4th among countries contributing to radiology research during the last 5 years.

Although feminism has been actively discussed and applied to nursing in Western societies since the 1980s, it is little known among Korean scholars as well as Korean nurses. This article explores the use of feminist perspectives in nursing science in other developed countries and suggests how feminism could be applied to nursing science in Korea. The literature related to nursing and feminism were reviewed in terms of nursing practice, education, and research. This article describes what feminism is and how feminism and nursing have evolved historically over time in other countries, especially in Western societies. In addition, it discusses how it can be applied to nursing practice, education, and research in Korea. Accepting feminist perspective in Korean nursing could benefit in empowering nurses by valuing nursing, by raising self-esteem of nurses, and by raising the consciousness of socio-political realities. Eventually it could benefit in changing and developing nursing science in Korea.

Vitamin D Status in Korea

Directory of Open Access Journals (Sweden)

Han Seok Choi

Full Text Available The majority of the vitamin D in our body is produced by cutaneous synthesis in response to sunlight. As more and more people live in cities and spend the bulk of their time indoors, it can be difficult to get sufficient sun exposure for adequate cutaneous production of vitamin D. Therefore, vitamin D insufficiency has become a very common health problem worldwide. The Korea National Health and Nutrition Examination Survey IV 2008 showed that the prevalence of vitamin D insufficiency, defined as a serum 25-hydroxyvitamin D [25(OHD] level below 50 nmol/L, was 47.3% in males and 64.5% in females. Only 13.2% of males and 6.7% of females had a serum 25(OHD level of greater than 75 nmol/L. In Korea, vitamin D insufficiency was more prevalent in young adults than in elderly people, likely due to the indoor lifestyle of younger people. Compared with the United States and Canada, Korea has a lower mean 25(OHD level and a higher prevalence of vitamin D insufficiency. To improve the vitamin D status of the Korean population, more aggressive policies on food fortification and vitamin D supplementation are needed.

This study was aimed at evaluating the lead (Pb) and cadmium (Cd) contamination status using resident pigeons from rural (island), central urban (Seoul), and four industrial complex areas in Korea with varying traffic density as well as atmospheric metal pollution records. We also discussed the results with respect to metal exposure trends in urban area after introduction of lead-free gasoline in Korea. Mean concentrations of Pb and Cd in bone and kidney of pigeons from Seoul were comparable to those from industrial complex areas and were about 15-20 times those at the reference site. This suggests that exposure to metals in the urban environment is as high as in the industrial areas. Lead and Cd concentrations in lungs of pigeons from Seoul were significantly higher by more than three times in 2000 than in 1991 (p < 0.01), whereas the residues in liver, kidney, and bone remained at a similar level, despite the introduction of unleaded gasoline in 1993. The Pb and Cd concentrations in tissues of pigeons did not decrease as atmospheric metal levels decreased. Ingestion may be more important than inhalation in exposing pigeons to Pb and Cd in this study

Following the expression of interest of the Republic of Korea in joining the ITER Negotiations, a technical delegation from the ITER International Team and the Participant Teams visited the country on 14-16 April 2003. The goal was to assess, through visits to laboratories and some relevant industries, the capability of the Republic of Korea to contribute 'in kind' to ITER construction. There is presently in the Republic of Korea a strong interest at Government and industry levels in supporting fusion research within the framework of the long term development of alternative energy supplies. The large investment in the Korean Superconducting Tokamak (KSTAR), a very ambitious project from a previously very limited programme, is a concrete demonstration of this interest and the expression of interest to participate in ITER follows the same line

2015-10-01

In South Korea, nationwide surveillance for severe fever with thrombocytopenia syndrome (SFTS) began during 2013. Among 301 surveillance cases, 35 hospitalized case-patients in 25 areas were confirmed by using virologic testing, and 16 (46%) case-patients subsequently died. The SFTS cases occurred during May-November and peaked during June (9 cases, 26%). The incidence of SFTS was higher in the southern regions of South Korea. Age and neurologic symptoms, including decreased level of consciousness and slurred speech, were heavily associated with death; neurologic symptoms during the first week after disease onset were also associated with death. Although melena was common among patients who died, no other hemorrhagic manifestations were substantively more common among those who died. No effective treatments, including ribavirin, were identified. Expansion of SFTS surveillance to include the outpatient sector and development of an antibody test would enhance completeness of SFTS detection in South Korea.

Possible effects of the Worldwide production of ethanol in two of the main countries that imports corn. South Korea and Mexico

Directory of Open Access Journals (Sweden)

2010-01-01

Full Text Available South Korea is the second largest importer of corn and Mexico is the third. Although the corn has its origin in this country, since 1994 Mexico has become one of the major importers in the world. This essay examines the possible economic implications for Mexico and Korea for the increased production of ethanol from corn. The analysis parts of the close relationship of three interconnected problems, which are at the root of the current energy crisis: global warming, oil crisis and biofuel production. This is causing a global food crisis. The production of ethanol from corn is emerging as an alternative that may address global warming and attacking the alleged shortage of oil, which has resulted in rising prices. The point in discussion is what are the possible effects of policies to induce the production of biofuels (ethanol on the main importers of corn. That’s why the current status of the ethanol industry is analyzed, whose main protagonists on the world stage are the United States and Brazil. Then we made a brief analysis of the market of corn. Finally, based on the foregoing, we reflect on the possible implications it might have on the development of food production of etanol.

Optimal allocation of energy sources for sustainable development in South Korea: Focus on the electric power generation industry

International Nuclear Information System (INIS)

Ahn, Joongha; Woo, JongRoul; Lee, Jongsu

2015-01-01

National energy planning has become increasingly complex owing to a pressing need to incorporate sustainability considerations. In this context, we applied least-cost and cost-risk optimization models to allocate energy sources for sustainable development in the Korean electric power generation industry. The least-cost model determined an electricity generation mix from 2012 to 2030 that incurs minimum generation cost to meet electricity demand. The cost-risk model determined electricity generation mixes in 2030 considering the risks associated with each energy source in order to lessen external risks. In deriving these optimal electricity generation mixes, we considered both conventional and renewable energy sources in conjunction with physical and policy constraints that realistically reflect Korean circumstances. Moreover, we accounted for CO 2 and external costs within the electricity generation costs for each energy source. For sustainable development in Korea, we conclude that a portion of the coal and gas in the electricity generation mix must be substituted with nuclear and renewable energy. Furthermore, we found that least-cost allocation is sub-optimal from cost-risk perspective and that it limits the adoption of renewables. Finally, we also discuss the implications of decisions taken by the Korean government regarding the electricity generation mix for next-generation energy planning to achieve sustainability. - Highlights: • Optimal least-cost/cost-risk energy mix for sustainable development in Korea. • We account for CO 2 and external costs of generation from each energy source. • Externalities and physical/policy constraints in Korea produce realistic energy mix. • Nuclear and renewables should replace coal and gas for sustainability in Korea. • Least-cost approach limits uptake of renewables and produces high-risk energy mix

The results of the study are aimed to assist counselors and educators who work with themes of grief and loss. From 17 in-depth interviews from parents bereaved by the Sewol ferry disaster of 2014 in South Korea, three main categories were found to capture the reality for parents after the sudden and traumatic death of a teenage child: (a) personal changes, (b) changes in close relationships, and (c) changes in social life. Recommendations for future research and potential implications were discussed.

How can Korea secure uranium enrichment and spent fuel reprocessing rights?

International Nuclear Information System (INIS)

Roh, Seungkook; Kim, Wonjoon

2014-01-01

South Korea is heavily dependent on energy resources from other countries and nuclear energy accounts for 31% of Korea's electric power generation as a major energy. However, Korea has many limitations in uranium enrichment and spent fuel reprocessing under the current Korea-U.S. nuclear agreement, although they are economically and politically important to Korea due to a significant problems in nuclear fuel storages. Therefore, in this paper, we first examine those example countries – Japan, Vietnam, and Iran – that have made nuclear agreements with the U.S. or have changed their agreements to allow the enrichment of uranium and the reprocessing of spent fuel. Then, we analyze those countries' nuclear energy policies and review their strategic repositioning in the relationship with the U.S. We find that a strong political stance for peaceful usage of nuclear energy including the legislation of nuclear laws as was the case of Japan. In addition, it is important for Korea to acquire advanced technological capability such as sodium-cooled fast reactor (SFR) because SFR technologies require plutonium to be used as fuel rather than uranium-235. In addition, Korea needs to leverage its position in nuclear agreement between China and the U.S. as was the case of Vietnam

Accurate precipitation estimates derived from space-borne satellite measurements are critical for a wide variety of applications such as water budget studies, and prevention or mitigation of natural hazards caused by extreme precipitation events. This study validates the near-real-time Early Run, Late Run and the research-quality Final Run Integrated Multi-Satellite Retrievals for GPM (IMERG) using Korean Quantitative Precipitation Estimation (QPE). The Korean QPE data are at a 1-hour temporal resolution and 1-km by 1-km spatial resolution, and were developed by Korea Meteorological Administration (KMA) from a Real-time ADjusted Radar-AWS (Automatic Weather Station) Rainrate (RAD-RAR) system utilizing eleven radars over the Republic of Korea. The validation is conducted by comparing Version-04A IMERG (Early, Late and Final Runs) with Korean QPE over the area (124.5E-130.5E, 32.5N-39N) at various spatial and temporal scales during March 2014 through November 2016. The comparisons demonstrate the reasonably good ability of Version-04A IMERG products in estimating precipitation over South Korea's complex topography that consists mainly of hills and mountains, as well as large coastal plains. Based on this data, the Early Run, Late Run and Final Run IMERG precipitation estimates higher than 0.1mm h-1 are about 20.1%, 7.5% and 6.1% higher than Korean QPE at 0.1o and 1-hour resolutions.

During the growing season of 2015, leaf specimens with yellow rust spots were collected from Salix koreensis Andersson, known as Korean willow, in riverine areas in Cheonan, Korea. The fungus on S. koreensis was identified as the rust species, Melampsora yezoensis , based on the morphology of urediniospores observed by light and scanning electron microscopy, and the molecular properties of the internal transcribed spacer rDNA region. Pathogenicity tests confirmed that the urediniospores are the causal agent of the rust symptoms on the leaves and young stems of S. koreensis . Here, we report a new rust disease of S. koreensis caused by the rust fungus, M. yezoensis , a previously unrecorded rust pathogen in Korea.

Full Text Available Hyperthyroidism is one of the causes of thyrotoxicosis and the most common cause of hyperthyroidism in Korea is Graves disease. The diagnosis and treatment of Graves disease are different according to geographical area. Recently, the American Thyroid Association and the American Association of Clinical Endocrinologists suggested new management guidelines for hyperthyroidism. However, these guidelines are different from clinical practice in Korea and are difficult to apply. Therefore, the Korean Thyroid Association (KTA conducted a survey of KTA members regarding the diagnosis and treatment of hyperthyroidism, and reported the consensus on the management of hyperthyroidism. In this review, we summarized the KTA report on the contemporary practice patterns in the diagnosis and management of hyperthyroidism, and compared this report with guidelines from other countries.

The characteristics of a ground motion attenuation in Korea and Japan were estimated by using the earthquake ground motions recorded at the equal distance observation station by KMA, K-NET and KiK-net of Korea and Japan. The ground motion attenuation equations proposed for Korea and Japan were evaluated by comparing the predicted value for the Fukuoka earthquake with the observed records. The predicted values from the attenuation equations show a good agreement with the observed records and each other. It can be concluded from this study that the ground motion attenuation equations can be used for the prediction of strong ground motion attenuation and for an evaluation of the attenuation equations proposed for Korea

The goal of this study was to build basic information related to the production and market of human vaccine products in Korea, which can be an important indicator to provide basic data in practical use. Statistical data were obtained from the Bank of Korea, Korea Health Industry Development Institute, Korea Pharmaceutical Traders Association, and Korea Pharmaceutical Manufacturers Association. Vaccines are the 10th ranked drugs in the classification of whole complete preparated drugs. The production output of vaccines in Korea was 392.2 billion KRW in 2011, comprising 2.83% of complete preparated drug production output (13 trillion 880.8 billion KRW) and 2.54% of medical-pharmaceutical product output (15 trillion 440.3 billion KRW). The market scale of vaccines in Korea was 710 billion KRW in 2011, with an annual average growth rate of 11% in the past 6 years, comprising 2% of vaccine market in the world. There was also a significant increase in essential vaccines and other preventive vaccines in a global scale. Vaccines have the potential of becoming an emerging attractive industry. Based on the current analysis about the production of vaccine products and market scale, further development of the vaccine industry is expected in Korea.

Korea nuclear exports: Why did the Koreans win the UAE tender? Will Korea achieve its goal of exporting 80 nuclear reactors by 2030?

International Nuclear Information System (INIS)

Berthelemy, Michel; Leveque, Francois

2011-01-01

The success of Korea in winning, in December 2009, a USD 18.6 billion nuclear tender in the United Arab Emirates (UAE) has led to a growing interest in the organization and strengths of the Korean nuclear industry. In this paper, we present the main economic and political factors that explain the success of the Korean consortium. In particular, thanks to an active national program of Nuclear Power Plant (NPP) construction, Korea has developed distinct competitive advantages in terms of low cost, high credibility and high performance. At the same time, due to the important barriers to enter into the nuclear export market in the UAE, Korea has had to sacrifice its profit margin and has benefited from a strong political support from its government through export financing. More importantly, Korea's success is also due to its alliance with Westinghouse and the support of the US diplomacy. Subsequently, we show that while Korea has recently experienced setbacks in nuclear tenders, it will most certainly try to win in the short run a second nuclear tender with another aggressive price. In the longer run, Korea could take a growing share of the international market for NPPs. However, the extent to which Korea can achieve its long term export target will depend upon its capacity to finance nuclear export through export credits and upon the development of its alliance with Westinghouse. It is important to note that this paper was written before the Fukushima nuclear disaster. The scale of the human and environmental consequences of this accident are still unknown, and will undoubtedly have short and long term consequences on nuclear safety requirements and public attitude toward nuclear energy, which will most certainly impact the outlooks for nuclear new-builds.

Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne viral disease. The SFTS virus (SFTSV) has been detected in the Haemaphysalis longicornis, which acts as a transmission host between animals and humans. SFTSV was first confirmed in China in 2009 and has also been circulating in Japan and South Korea. However, it is not known if a genetic connection exists between the viruses in these regions and, if so, how SFTSV is transmitted across China, South Korea, and Japan. We therefore hypothesize that the SFTSV in South Korea share common phylogenetic origins with samples from China and Japan. Further, we postulate that migratory birds, well-known carriers of the tick H. longicornis, are a potential source of SFTSV transmission across countries. Our phylogenetic analysis results show that the SFTSV isolates in South Korea were similar to isolates from Japan and China. We connect this with previous work showing that SFTSV-infected H. longicornis were found in China, South Korea, and Japan. In addition, H. longicornis were found on migratory birds. The migratory bird routes and the distribution of H. longicornis are concurrent with the occurrence of SFTSV. Therefore, we suggest that migratory birds play an important role in dispersing H. longicornis-borne SFTSV. © The American Society of Tropical Medicine and Hygiene.

2018-03-01

Organisms entering the East Sea (Sea of Japan) through the Korea Strait, together with water, salt, and energy, affect the East Sea ecosystem. In this study, we report on the biodiversity of eukaryotic plankton found in the Western Channel of the Korea Strait for the first time using small subunit ribosomal RNA gene (18S rDNA) sequences. We also discuss the characteristics of water masses and their physicochemical factors. Diverse taxonomic groups were recovered from 18S rDNA clone libraries, including putative novel, higher taxonomic entities affiliated with Cercozoa, Raphidophyceae, Picozoa, and novel marine Stramenopiles. We also found that there was cryptic genetic variation at both the intraspecific and interspecific levels among arthropods, diatoms, and green algae. Specific plankton assemblages were identified at different sampling depths and they may provide useful information that could be used to interpret the origin and the subsequent mixing history of the water masses that contribute to the Tsushima Warm Current waters. Furthermore, the biological information highlighted in this study may help improve our understanding about the complex water mass interactions that were highlighted in the Korea Strait.

Contextual Factors Affecting the Innovation Performance of Manufacturing SMEs in Korea: A Structural Equation Modeling Approach

Full Text Available This study empirically explores the relationship between innovation performance and the internal and contextual factors driving technological innovation in manufacturing small and medium-sized enterprises (SMEs in metropolitan areas of Korea using structural equation modeling (SEM. Our analysis is based on firm-level data from the Korean Innovation Survey conducted by the Science and Technology Policy Institute in 2012. According to the results, SMEs’ innovation capacity was positively related to technological innovation performance, and SMEs’ skills and technology acquisition is a contextual factor that positively influences their innovation performance. In this process, SMEs’ innovation capacity is a partial mediator between skills and technology acquisition and SMEs’ technological innovation performance. Moreover, the results show that the relationship between government and public policies and SMEs’ innovation performance is mediated by SMEs’ internal innovation capacity. The results imply that both skills and technology acquisition and government and public policies are important contextual factors can increase SMEs’ innovation performance. Based on the results, this study provides implications for policy makers in terms of the policies that provide both direct and support roles in fostering and sustaining innovation, which drives regional economic growth and development.

2017-12-01

We used remote sensing data to detect the changes on surface and ionosphere due to the North Korea nuclear test. To analyze the surface deformation before and after the 6th North Korea (NK) nuclear test, we used Satellite Aperture Radar (SAR) images. It was reported that there were some surface deformation with about 10 cm by the 4th test (Wei, 2017) and the 5th test (Jo, 2017) using Interferometric SAR (InSAR) technique. However we could not obtain surface deformation by the 6th test using InSAR with Advanced Land Observation Satellite 2 (ALOS-2) data because of low coherence in the area close to the epicenter. Although the low coherence can be occurred due to several reasons, the main reason may be large deformation in this particular case. Therefore we applied pixel offset method to measure the amount of surface deformation in the area with low coherence. Pixel offset method calculates the deformation in the directions along track and Line-of-Sight (LOS) using cross correlation of intensity of two SAR images before and after the event for a pixel and is used frequently to obtain large deformation of glacier (e.g. Lee et al., 2015). Applying pixel offset method to the area of the 6th NK nuclear test, we obtained about 3 m surface deformation in maximum. It seems that the larger deformation occurs as the mountain slope is steeper.We then analyzed ionospheric perturbation using Global Navigation Satellite System (GNSS) data. If acoustic wave by a nuclear test goes up to the ionosphere and disturbs electron density, then the changes in slant total electron content (STEC) may be detected by GNSS satellites. STEC perturbation has been reported in the previous NK nuclear tests (e.g. Park et al., 2011). We analyzed the third order derivatives of STEC for 51 GNSS stations in South Korea and found that some perturbation were appeared at 4 stations about 20 40 minutes after the test.

Impact of macro-level socio-economic factors on rising suicide rates in South Korea: panel-data analysis in East Asia.

Science.gov (United States)

Hong, Jihyung; Knapp, Martin

2014-12-01

The rapid increase in suicide rates in South Korea, particularly in the aftermath of the Asian economic crisis in the late 1990s, compares with the declining suicide rates observed in most other OECD countries over the same period. This study aimed to examine an array of macro-level societal factors that might have contributed to the rising suicide trend in South Korea. We first investigated whether this trend was unique to South Korea, or ubiquitous across five Asian countries/areas that are geographically and culturally similar (South Korea, Hong Kong, Japan, Singapore, and Taiwan), using WHO mortality data and national statistics (1980-2009). Age-standardised suicide rates (per 100,000 population) were calculated for each gender and age group (15-24, 25-44, 45-64, and 65+) for each country. Both panel data and country-specific time-series analyses were employed to investigate the impact of economic change and social integration/regulation on suicide. Despite similarities in geography and culture, the rising trend of suicide rates was unique to South Korea. This atypical trend was most apparent for people aged 65 and over, which was in sharp contrast to the decreasing suicide trends observed in the other four Asian countries. The results of the panel data analyses generally pointed to a negative relationship between economic growth and suicide rates, particularly for working-aged people. The results of the time-series analyses further suggested that low levels of social integration, as indicated by rising divorce rates, may also have a role in rising suicide rates in South Korea, particularly for older people. Furthermore, the association between suicide rates and economic adversity (unemployment and economic downturn) was most salient among middle-aged men in South Korea. Compared to four other East Asian countries/areas (Hong Kong, Japan, Singapore, and Taiwan), South Korea has uniquely experienced a rising trend of suicide rates over the past three decades

Beyond risk: a psychometric and cultural analysis of risk percepion in Korea

International Nuclear Information System (INIS)

Choi, Byung-Sun; Chung, Ik Jae

2002-01-01

A survey of technological risk perception in Korea was administered in 2001 with a special emphasis on nuclear risks. This paper summarizes the characteristics of risk perception through the analytic lens of psychometric paradigm. A group of experts identified 8 dimensions of risk; voluntariness, severity, effect manifestation, exposure pattern, controllability, familiarity, benefit and necessity. The survey with sample size of 1870 evaluates the perceived level of 25 technological risks including transportation, chemicals, environmental, industrial, as well as nuclear areas. Research findings confirm that the risk characteristics or dimensions are significant predictors of risk perception. Nuclear risks are perceived as involuntary, catastrophic, delayed, occasional, controllable, beneficiary, unfamiliar, and necessary. The paper underlines the need and the importance of nuclear power generation as an environmentally-friendly energy resource in Korea. Effective risk communication can improve the awareness and the understanding of nuclear risks as well as other technological risk, and ultimately foster the public acceptance of nuclear facilities

Disasters can strike uncontrollably whenever or wherever, leaving horrendous marks of physical and psychological damage on people upon their passing. Asia remains the most widely affected area of the world, with high death tolls, casualties, and economic losses recorded in past years. In fact, a developed country like South Korea incurs huge deficits from disaster-related adversities. Restoration efforts and assistance for disaster survivors are generously provided by the Korean government. However, it is only recently that cases of postdisaster mental problems have been given attention. This article argues that, although material relief helps disaster victims to regain their physical losses, it is equally important to aid their psychological needs to prevent long-term mental health problems. This article highlights Korea's first regional Psychological Support Center for disaster victims, which can be accessed online. With this Center, the country continues to strive in providing her people with holistic approaches to further enhance each citizen's quality of life.

Environmental Implications of Eco-Labeling for Rice Farming Systems

Full Text Available Concerns about climate change have forced countries to strengthen regulations, standards, and certifications related to greenhouse gas emissions. Various policies targeting farm products, such as carbon labeling and the Environmentally-Friendly Agricultural Product Certification (EFAPC for agricultural products, have been implemented in South Korea to reduce greenhouse gas emissions in the agricultural sector. The purpose of this study was to evaluate the implications of the various certification systems for rice farming, including organic farming, non-pesticide farming, and low-pesticide farming. For this study, we constructed a life cycle inventory (LCI of rice farming systems including conventional, low-pesticide, non-pesticide, and organic farming systems in South Korea. Finally, we compared international farming systems in South Korea, the U.S., and the EU. The rice farming systems with eco-labeling certifications have reduced the environmental impacts. The environmental impacts of rice farming by country were highest in the U.S. (100.0, followed by the EU (53.7, and Korea’s conventional (48.6, low-pesticide (35.8, non-pesticide (28.9, and organic (16.7 farming practices. These results may be useful in proliferating and improving the methodology to evaluate eco-labeling and carbon labeling systems.

Cancer is the leading cause of death for Korean-Americans (KAs), while cancer screening rates among KAs have been consistently low. Seven semi-structured focus group interviews with 34 KA women aged 40 or older in the Washington, DC metropolitan area were conducted to explore the perceptions of KA women about seeking physical examinations and cancer screening services in Korea. Data were analyzed using a framework approach. Informants positively perceived the use of health screening services in Korea in comparison to seeking such services in the US. Decision-making factors included cost benefits, high quality services, and more convenient screening procedures in Korea. These benefits outweighed the risks of delaying health care and travelling a vast distance with incurring additional travel costs. Motivations to seek these services in Korea included opportunities to visit their homeland and to enjoy comfortable communication with their native language. The increase of available information about Korean medical services due to the industry's aggressive marketing/PR was identified as a facilitator. Most informants did not recognize possible negative health outcomes of obtaining services in Korea such as inappropriate follow up care if having abnormal findings. Educational programs are needed to educate KAs about the benefits and risks of getting the services in Korea and proper follow up care in the US. Health care providers need to know the different cancer risks and screening needs for this population.

The Current Status of The Clinical Application of Radioisotope in Korea

The medical application of radioisotope started in the western countries in the 1920's but the first successful clinical use of Nuclear Medicine in Korea was made in June, 1959, through the treatment of a patient with hyperthyroidism using radioactive iodine. However, keeping pace with the brilliant international development of nuclear medicine, nuclear medicine in Korea has remarkably grown scientifically; The Korean Society of Nuclear Medicine was organized in 1961, The Radiology Science Institute attached to the Korea Atomic Energy Research Institute, the predecessor of the Korea Cancer Center Hospital, was established in 1963, and The Korean Journal of Nuclear Medicine published its first issue in 1967. Furthermore, the active studies using radioisotopes and the vigorous interchanges of information with foreign countries had increased so steadily and remarkably that we could hold the 3rd Asia and Oceania Congress of Nuclear Medicine in 1984. In Korea, Nuclear Medicine has now settled as a field of a science which interests lots of medical doctors and scientists. However, I cannot deny the fact that the progress of the development of Nuclear Medicine in Korea tends to defer relatively to that of the western countries, which is naturally a very active one, in many respects. I here would like to analyze the current status of clinical application of radioisotope in Korea, find the problems and present their solutions

Full Text Available In today’s global age many people cross national borders in search of better work and more wages. According to IOM, more than 100 000 000 workers leave their homeland and migrate to another country for this reason. Europe and North America have already experienced increase in foreign labor for many decades but nowadays, it is very common to see foreign laborers in Asian countries. As the number of foreign laborers rapidly increased, however, so did many social problems in relation to these workers. No country is safe from or immune to such social problems in regards to the foreign workers especially with a much easier and more efficient transportation system. In case of South Korea, the history of foreign labor may not be as long as other nations but as of 2007, it boasts of more than 250 000 foreign laborers and is thus facing just as many social problems as well. In order to investigate such social issues, this article explores the history of foreign laborers and their current situation in South Korea. Furthermore, this artticle examines both internal and external factors which may have caused exponential growth of foreign labor market in South Korea in the past decade.

Zostera caulescens is an endemic seagrass species in Northeastern Asia. Estimated distributional area of this species is approximately 1-5 km2 on the coasts of Korea. Because Z. caulescens has a very limited distribution, the growth dynamics of Z. caulescens is little known in the coastal waters of Korea. In the present study, we investigated the growth dynamics of Z. caulescens in relation to coincident measurements of environmental factors, such as underwater irradiance, water temperature, and nutrient availability. The study was conducted on a monotypic meadow of Z. caulescens in Uljin on the eastern coast of Korea from September 2011 to September 2012. Shoot density and biomass of Z. caulescens showed distinct seasonal variations, and exhibited strong correlations with water temperature suggesting that the seasonal growth of this species was regulated by water temperature. Shoot density and biomass rapidly decreased during the high water temperature period in summer, and thus Z. caulescens is considered a cold water adapted species like other temperate seagrass species on coasts of Korea. Biomass of photosynthetic leaf tissues on reproductive shoots was approximately 4 times higher than that on vegetative shoots. The height of reproductive shoots ranged from 1.2 m in February 2012 to 3.2 m in August 2012, whereas the height of vegetative shoots was usually less than 1.0 m. Leaf tissues on reproductive shoots probably received much more light for photosynthesis than those on vegetative shoots. Thus, reproductive shoots may play an important role in total production of Z. caulescens.

Toxicity and persistence of perfluorinated alkyl substances (PFASs) in human have raised considerable concern and several biomonitoring studies throughout the world reported the widespread occurrence of these compounds in human tissues. However, information regarding influence of geographic, lifestyle and demographic factor on PFAS levels in human blood tissues is limited. In this study, whole blood samples collected in 2006–2007 from 319 donors from suburban Seoul (Suwon and Yongin), Busan and Yeosu in Korea were analyzed for perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), perfluorononanoate (PFNA), perfluorohexane sulfonate (PFHxS) and perfluorooctane sulfonamide (PFOSA). Blood donors classified into seven age groups with ages ranging from 8 to 82 years, and different lifestyles and socio-economic status. PFOS (median = 4.15 ng/mL) was found at the highest concentration with a maximum concentration of 59.1 ng/mL. The concentrations of other PFASs were in the decreasing order of; PFOA (median = 1.30 ng/mL) > PFNA (median = 0.85 ng/mL) > PFHxS (median = 0.47 ng/mL) > PFOSA (median = 0.12 ng/mL). Geographical differences in the concentrations of five target PFASs were found. Significant positive relationships between PFAS concentrations and the age of the donors were found. Gender-related differences were found in the concentrations of PFOA, PFNA, PFHxS and PFOSA. No association was found between PFAS levels and several lifestyle factors and socio-economic status which included drinking habit, furniture/carpet in an indoor environment and monthly income. Occupation was an important determinant for PFNA and PFHxS concentrations in the whole blood. Except for PFOSA, significant associations were noted between PFASs concentrations and smoking habit. The results of this study provide information for further public health monitoring and safety management for PFASs in Korea. - Highlights: • Significant geographical differences in PFAS levels in whole

Toxicity and persistence of perfluorinated alkyl substances (PFASs) in human have raised considerable concern and several biomonitoring studies throughout the world reported the widespread occurrence of these compounds in human tissues. However, information regarding influence of geographic, lifestyle and demographic factor on PFAS levels in human blood tissues is limited. In this study, whole blood samples collected in 2006–2007 from 319 donors from suburban Seoul (Suwon and Yongin), Busan and Yeosu in Korea were analyzed for perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), perfluorononanoate (PFNA), perfluorohexane sulfonate (PFHxS) and perfluorooctane sulfonamide (PFOSA). Blood donors classified into seven age groups with ages ranging from 8 to 82 years, and different lifestyles and socio-economic status. PFOS (median = 4.15 ng/mL) was found at the highest concentration with a maximum concentration of 59.1 ng/mL. The concentrations of other PFASs were in the decreasing order of; PFOA (median = 1.30 ng/mL) > PFNA (median = 0.85 ng/mL) > PFHxS (median = 0.47 ng/mL) > PFOSA (median = 0.12 ng/mL). Geographical differences in the concentrations of five target PFASs were found. Significant positive relationships between PFAS concentrations and the age of the donors were found. Gender-related differences were found in the concentrations of PFOA, PFNA, PFHxS and PFOSA. No association was found between PFAS levels and several lifestyle factors and socio-economic status which included drinking habit, furniture/carpet in an indoor environment and monthly income. Occupation was an important determinant for PFNA and PFHxS concentrations in the whole blood. Except for PFOSA, significant associations were noted between PFASs concentrations and smoking habit.

Full Text Available Weekly rain samples were collected in coastal areas of the Shihwa Basin (Korea from June 2000 to November 2007. The study region includes industrial, rural, and agricultural areas. Wet precipitation was analyzed for conductivity, pH, Cl−, NO3−, SO42−, Na+, K+, Mg2+, NH4+, and Ca2+. The major components of precipitation in the Shihwa Basin were NH4+, volume-weighted mean (VWM of 44.6 µeq∙L−1, representing 43% of all cations, and SO42−, with the highest concentration among the anions (55% at all stations. The pH ranged from 3.4 to 7.7 with a VMM of 4.84. H+ was weakly but positively correlated with SO42− (r = 0.39, p < 0.001 and NO3− (r = 0.38, p < 0.001. About 66% of the acidity was neutralized by NH4+ and Ca2+. The Cl−/Na+ ratio of the precipitation was 37% higher than seawater Cl−/Na+. The high SO42−/NO3− ratio of 2.3 is attributed to the influence of the surrounding industrial sources. Results from positive matrix factorization showed that the precipitation chemistry in Shihwa Basin was influenced by secondary nitrate and sulfate (41% ± 1.1%, followed by sea salt and Asian dust, contributing 23% ± 3.9% and 17% ± 0.2%, respectively. In this study, the annual trends of SO42− and NO3− (p < 0.05 increased, different from the trends in some locations, due to the influence of the expanding power generating facilities located in the upwind area. The increasing trends of SO42− and NO3− in the study region have important implications for reducing air pollution in accordance with national energy policy.

The National Forensic Service (NFS) of Korea is a government agency responsible for examining and evaluating evidence obtained at crime scenes. The Section of Forensic Odontology of the Medical Examiner's Office conducts forensic odontological analyses of human remains, and mainly criminal cases are handled. In this study, 588 forensic odontological cases referred to NFS during 2011-2015 were analyzed for referral pattern, evidence material, examination criteria, and other factors and were compared with respective data from 2007 to 2010. Majority of the requests were internal (further dental examinations after autopsy) rather than external (direct requests from other agencies such as police departments). Regarding evidence materials, "Teeth" (including teeth and resected jaws) were dominant evidences. Due to the seasonal effects in Korea, the highest number of requests was in September of each year, but the number of requests in April has recently increased. Evidence materials were mostly found in suburban and rural area, especially in mountainous area due to the geographic characteristics of Korea. Regarding specific examinations, profiling, including age estimation, accounted for majority of the requests; this number had increased relative to the findings of a previous study, whereas the number of requests for dental identification and bite mark analysis had decreased. With this analysis, trends in forensic odontology can be observed, and we expect that these trends would be served as a reference for designing study and making training protocol for forensic odontology.

Becoming an International Scientist in South Korea: Ho Wang Lee’s Research Activity about Epidemic Hemorrhagic Fever

Directory of Open Access Journals (Sweden)

Miyoung SHIN

2017-04-01

Full Text Available In the 1960-70s, South Korea was still in the position of a science latecomer. Although the scientific research environment in South Korea at that time was insufficient, there was a scientist who achieved outcomes that could be recognized internationally while acting in South Korea. He was Ho Wang Lee(1928~ who found Hantann Virus that causes epidemic hemorrhagic fever for the first time in the world. It became a clue to identify causative viruses of hemorrhagic diseases that were scattered here and there throughout the world. In addition, these outcomes put Ho Wang Lee on the global center of research into epidemic hemorrhagic fever. This paper examines how a Korean scientist who was in the periphery of virology could go into the central area of virology. Also this article shows the process through which the virus found by Ho Wang Lee was registered with the international academia and he proceeded with follow-up research based on this progress to reach the level at which he generalized epidemic hemorrhagic fever related studies throughout the world. While he was conducting the studies, experimental methods that he had never experienced encountered him as new difficulties. He tried to solve the new difficulties faced in his changed status through devices of cooperation and connection. Ho Wang Lee’s growth as a researcher can be seen as well as a view of a researcher that grew from a regional level to an international level and could advance from the area of non-mainstream into the mainstream. This analytic tool is meaningful in that it can be another method of examining the growth process of scientists in South Korea or developing countries.

South Korea has experienced extreme droughts in 1994-1995, 2000-2001, 2012, 2015, and 2016-2017. The 2017 spring drought (with especially low winter precipitation recorded in winter 2016) affected a large portion of central and western South Korea, and was one of the most severe droughts in the region since the 2000-2001 drought. The spring drought of 2017 was characterized by exceptionally low precipitation with total precipitation from January to June being 50% lower than the mean normal precipitation record (1981-2010) over most of western South Korea. It was the climatologically driest spring over the 1961-2016 record period. Effective drought monitoring and management depends on which drought indices are selected because each drought index has different drought criteria or levels of drought severity, associated with drought responses. In this study, for the quantitative analysis of the spring 2017 drought event in South Korea, four widely-used drought indices, including the Standardized Precipitation Index (SPI), the Standardized Precipitation Evapotranspiration Index (SPEI), the Self-Calibrated Palmer Drought Severity Index (SC-PDSI), and the Effective Drought Index (EDI) are compared with observed drought damaged areas in the context of agricultural drought impacts. The South Korean government (Ministry of Agriculture, Food and Rural Affairs (MAFRA) and Korea Rural Community Corporation (KRC)) has been operating a government-level drought monitoring system since 2016. Results from this study can be used to improve the drought monitoring applications, as well as drought planning and preparedness in South Korea.

The aim of this study was to assess the prevalence of complementary and alternative medicines (CAM) use for managing pain and to investigate the factors predictive of current CAM use among rural older women in South Korea. Access to medical care among older adults in rural areas is poorer than in urban areas. A cross-sectional descriptive study with a stratified sample of 139 women aged over 65 with chronic pain residing in rural areas of Jeju Island, South Korea. A self-reported questionnaire was used to collect data. Most subjects reported using at least one type of CAM for relieving pain within the past 12 months. Almost half of them reported currently using CAM. Herbs were the most commonly used CAM. Only 'severity of pain' was presently associated with an increased use of CAM. It is imperative to take socio-geographic-cultural factors into consideration when planning health promotion programs and caring for clients. © 2013.

The primary water stress corrosion cracking (PWSCC) of alloy 600 in a PWR has been reported in the control rod drive mechanism (CRDM). Beginning in the mid-seventies, the pressurized water reactor (PWR) plants suffered from a sequence of SCC events mostly confined to S/G tubes, initially ODSCC, and then PWSCC. PWSCC was first reported in Bugey 3 vessel head penetration made of forged alloy 600 materials in September 1991. Other PWRs experienced cracking attributed to the PWSCC of the major primary side weld area made from alloy 182 at the end of the year 2000. Examples of dissimilar metal butt welds between the main austenitic stainless steel primary circuit piping and the outlet pressure vessel nozzles are the cracking of Ringhals 4, V. C. Summer and some J-groove welds of the CRDM of the RVH at Oconee 1. In addition to the Reactor Vessel Head (RVH), the PWSCC of alloy 182/82 has been reported at bottom mounted instrumentation (BMI) nozzle J-welds, steam generator(SG) J-weld drain nozzle, and SG tube sheet cladding. Two cases of boric acid precipitation were reported at the bottom head surface of a SG in Korea. Cracking was found in the cold leg drain nozzles made of alloy 600 in two units, hot side nozzles were fabricated with alloy 690 from the beginning. The cracking of steam generator tubings made of alloy 600 is another concern in Korea, because some plants still have alloy 600 HTMA tubings. The flow accelerated corrosion of secondary pipings is another type of corrosion problems, though it has not been treated as a severe problem in Korea. To properly manage the corrosion issues and seek out research items for maintaining the integrity of nuclear plants, the PRIMA-Net (Proactive Research and Innovative Material Aging Network) was organized in 2007. The research and development expert group consists of a National research laboratory (KAERI), regulatory body (KINS), utility (KHNP), engineering and design company (KEPCO EC), manufacturer (Doosan Heavy

Progress of Nuclear Hydrogen Program in Korea

Lee, Won Jae

2009-01-01

To cope with dwindling fossil fuels and climate change, it is clear that a clean alternative energy that can replace fossil fuels is required. Hydrogen is considered a promising future energy solution because it is clean, abundant and storable and has a high energy density. As other advanced countries, the Korean government had established a long-term vision for transition to the hydrogen economy in 2005. One of the major challenges in establishing a hydrogen economy is how to produce massive quantities of hydrogen in a clean, safe and economical way. Among various hydrogen production methods, the massive, safe and economic production of hydrogen by water splitting using a very high temperature gas-cooled reactor (VHTR) can provide a success path to the hydrogen economy. Particularly in Korea, where usable land is limited, the nuclear production of hydrogen is deemed a practical solution due to its high energy density. To meet the expected demand for hydrogen, the Korea Atomic Energy Institute (KAERI) launched a nuclear hydrogen program in 2004 together with Korea Institute of Energy Research (KIER) and Korea Institute of Science and Technology (KIST). Then, the nuclear hydrogen key technologies development program was launched in 2006, which aims at the development and validation of key and challenging technologies required for the realization of the nuclear hydrogen production demonstration system. In 2008, Korean Atomic Energy Commission officially approved a long-term development plan of the nuclear hydrogen system technologies as in the figure below and now the nuclear hydrogen program became the national agenda. This presentation introduces the current status of nuclear hydrogen projects in Korea and the progress of the nuclear hydrogen key technologies development. Perspectives of nuclear process heat applications are also addressed

Information on drug resistance and transmission patterns of tuberculosis (TB) in foreign-born patients is lacking in Asia where immigration is increasing. We examined the drug-resistance profiles of 288 Mycobacterium tuberculosis isolates from foreign-born patients in South Korea, and assessed for potential transmission in the host country by analysing their IS6110 genotypes, as well as those of 4780 strains from native Korean TB patients. The prevalence of multidrug-resistant (MDR) TB was 9.7% and 42% among new and previously treated patients, respectively. Chinese nationality was associated with MDR TB (OR(China)=3.0, 95% CI 1.1-9.3). Of the 288 strains, 51 (17.7%) formed 31 clusters, of which 22 were identical to strains from native Koreans. A number of strains belonged to the K family, subtypes known to occur endemically in Korea. MDR TB was common, and clustering patterns showed potential cross-cultural transmission among foreign-born TB patients. Further molecular epidemiological studies of all isolates in the area are needed to determine the extent of international TB transmission in Asia. © 2011 SGM

South Korea has had remarkably high incidence and prevalence rates of physical violence against children, yet the problem has received only limited public and professional attention until very recently. This article represents the first attempt in English to systematically analyze South Korea's recent epidemiological studies on child maltreatment. Discussed are sociocultural factors that have contributed both to delays in child protection laws and a low public awareness of the problem of child abuse. The article highlights methodological issues concerning the definition of physical abuse in South Korea and the complex attitudes toward violence. It also examines the role of the Korean women's movement in the reform of family laws and the recent establishment of new child protection legislation. Suggestions for future directions for the problem of child maltreatment within South Korea are presented.

Full Text Available Two cold-water coral taxa, Octocorallia in the class Anthozoa and Stylasteridae in the class Hydrozoa, were identified. Deep-water samples were collected in fishing nets at depths ranging between 20 and 200 m along the coasts of the East Sea in Korea from 1976 to 1993. The two species found in this study represent new records for Korea: Paragorgia arborea (Linnaeus, 1758 in the class Anthozoa, and Stylaster profundiporus Broch, 1936 in the class Hydrozoa. Two families, Paragorgiidae and Stylasteridae, are also newly recorded in Korea. Furthermore, the species name of another cold-water gorgonian species, Primnoa pacifica (Kinoshita, 1907 in the family Primnoidae, is amended in this report. The two newly recorded cold-water coral species from Korea are described in detail based on their morphological characteristics. Paragorgia arborea is characterized by its growth form, medulla and cortex, zooid dimorphism, canal system, and spicule composition. Stylaster profundiporus is distinguished by its external skeletal characteristics, such as the coordination of dactylopores and gastropores, presence or absence of gastrostyles and dactylostyles, cyclosystem orientation, ampullar position, gastropore tube shape, and coenosteal texture.

The national long-term R and D program, updated in 1977, requires Korea Atomic Energy Research Institute (KAERI) to complete by the year 2006 the basic design of Korea Advanced Liquid Metal Reactor (KALIMER), along with supporting R and D work, with the capability of resolving the issue of spent fuel storage as well as with significantly enhanced safety. KALIMER is a 150 Mwe pool-type sodium cooled prototype reactor that uses metallic fuel. The conceptual design is currently under way to establish a self-consistent design meeting a set of major safety design requirements for accident prevention. Some of the current emphasis includes those for inherent and passive means of negative reactivity insertion and decay heat removal, high shutdown reliability, prevention of and protection from sodium chemical reaction, and high seismic margin, among others. All of these requirements affect the reactor design significantly and involve extensive supporting R and D programs. This paper summarizes some of the results of conceptual engineering and design analyses performed for the safety of KALIMER in the area of inherent safety, passive decay heat removal, sodium water reaction, and seismic isolation.

Scrub typhus is an endemic disease in Asia. It has been a rural disease, but indigenous urban cases have been observed in Seoul, South Korea. Urban scrub typhus may have a significant impact because of the large population. Indigenous urban scrub typhus was epidemiologically identified in Seoul, the largest metropolitan city in South Korea, using national notifiable disease data from 2010 to 2013. For detailed analysis of clinical features, patients from one hospital that reported the majority of cases were selected and compared to a historic control group. Chigger mites were prospectively collected in the city using a direct chigger mite-collecting trap, and identified using both phenotypic and 18S rDNA sequencing analyses. Their infection with Orientia tsutsugamushi was confirmed by sequencing the 56-kDa antigen gene. Eighty-eight cases of urban scrub typhus were determined in Seoul. The possible sites of infection were mountainous areas (56.8%), city parks (20.5%), the vicinity of one's own residence (17.0%), and riversides (5.7%). Eighty-seven chigger mites were collected in Gwanak mountain, one of the suspected infection sites in southern Seoul, and seventy-six (87.4%) of them were identified as Helenicula miyagawai and eight (9.2%) as Leptotrombidium scutellare. Pooled DNA extracted from H. miyagawai mites yielded O. tsutsugamushi Boryong strain. Twenty-six patients from one hospital showed low APACHE II score (3.4 ± 2.7), low complication rate (3.8%), and no hypokalemia. We identified the presence of indigenous urban scrub typhus in Seoul, and a subgroup of them had mild clinical features. The chigger mite H. miyagawai infected with O. tsutsugamushi within the city was found. In endemic area, urban scrub typhus needs to be considered as one of the differential febrile diseases and a target for prevention.

2011-01-01

The prospects for growth of the nuclear power industry in Korea have improved remarkably as the demand for energy increases in stride with economic development. Meanwhile, as nuclear energy development is enhanced, nuclear technology has also improved evolutionarily and innovatively in the areas of reactor design and safety measures. As nuclear technology development in Korea advances, more human resources are required. Accordingly, the need for a well-managed program of human resource development (HRD) aimed at assuring needed capacities, skills, and knowledge and maintaining valuable human resources through education and training in various nuclear-related fields has been recognized. A well-defined and object-oriented human resource development and management (HRD and M) is to be developed in order to balance between the dynamics of supply and demand of the workforce in the nuclear industry. The HRD and M schemes include a broad base of disciplines, education, sciences, and technologies within a framework of national sustainable development goals, which are generally considered to include economics, environment, and social concerns. In this study, the projection methodology considering a variety of economic, social, and environmental factors was developed.

Purpose Vitiligo prevalence and its associated comorbidities rate have been reported variably among different populations. We aimed to determine the prevalence of vitiligo in Korea along with the baseline rate of comorbidities and compared the risks to the general population using hospital visit information of the total population in Korea. Materials and Methods We assessed demographic characteristics of vitiligo patients in Korean population from 2009 to 2011 in a nationwide data from Health Insurance Review Assessment Service. Patients who had at least one visit to Korea's primary, secondary, or tertiary referral hospitals with International Classification of Diseases, 10th Revision, Clinical Modification diagnosis code for vitiligo were identified. As a supplementary study, comorbidities associated with vitiligo were selected for further review to calculate relative risks compared to the general population. Results The annual prevalence of vitiligo determined by hospital-visiting rate in Korea was 0.12% to 0.13% over a three year period. In sync with other previous epidemiological studies, there was bimodal distribution among the age groups and no difference between genders. Also, vitiligo in Korean population was associated with various autoimmune/non-autoimmune diseases such as thyroiditis, atopic dermatitis, and psoriasis. Conclusion This study was by far the most comprehensive review on prevalence of vitiligo using a data of total population in Korea. The prevalence is within a range of those reported in previous literatures, and increased risk of comorbidities such as thyroid diseases and psoriasis in vitiligo might aid clinicians in the initial work up of vitiligo patients and concurrent follow ups.

Full Text Available For many years the Soviet Union was the key economic partner of North Korea. After the USSR broke up, Russia has not played such an important role in the DPRK's economic development. In 2013, its share in the foreign trade of North Korea accounted for a mere 1%. However, in the second decade of the 21st century bilateral, contacts have intensified significantly. Judging by the recent developments, the Russian leadership has made a political decision to expand economic cooperation with North Korea and stimulate Russia's business interests with the DPRK. Russia has set a goal of growing the volume of its trade with North Korea by a factor of ten by 2020. Moreover, Moscow is currently developing a number of investment projects in the DPRK and Russian companies are also looking at developing more of them. Another important aim for Russia is the implementation of big infrastructure projects with both Koreas. The article examines the current position and future prospects for economic cooperation between Russia and North Korea and analyses main forms and potential opportunities for developing bilateral economic relations. Particular attention is paid to the expanding cooperation mechanisms and joint economic projects between Russia and the DPRK and also the potential participation of the Republic of Korea.

Renewable energy (RE) is the best sustainable energy solution South Korea can provide to assist North Korea in overcoming its chronic energy shortage. Designed as a follow-on research to Sin et al., a survey was conducted with a panel of experts consisting of various disciplines and affiliations using the analytic hierarchy process (AHP) with benefit, opportunity, cost, and risk (BOCR). The results showed the panel viewed security as the most important factor among the strategic criteria. For the level 1 attributes, the panel showed no significant differences of opinion among the different alternatives; however, cost showed to be the most important factor for the panel. The panel chose wind power as the best alternative source of energy for North Korea; however, there were some differences in opinion among the sub-groups of the panel depending on the composition and the expertise of the sub-group. Compared to other studies on the similar topic, this research stands out in that the research results were derived using AHP and BOCR and that the panel was composed of both Korean and foreign experts on North Korea affiliated with state-run research organizations, armed forces, non-governmental organizations, academic research organizations, private consulting firms, and journalism. The research arrived at the conclusion that the following factors must be considered as South Korea designs its future North Korean energy assistance policy: (1) RE assistance for North Korea can take on various forms; hence, experts consulted during the design, writing, and implementation phases of the policy in question must possess knowledge and expertise in the appropriate technology and methodology being considered; (2) possibility of a sudden destabilization of the Northeast Asian security paradigm due to the collapse of North Korea; and (3) continued nuclearization of North Korea.

The history of South Korea is confined in the history of the nations that from the opening from East to the West in the middle of century XIX play a important role like scene and reason for conflicts between the regional powers and, after 2ª World War, like scene of the conflict between the two superpowers. The objective of the present work is present Korea like a typical scene of the game of powers that represent geopolitics, for such effect is divided in three approaches: first it has to do with the geography of Korea like a strategic zone disputed by China, Japan and Russia in the middle of century XIX? the second approach talks about to the location of Korea like a geopolitical space where the two great triumphant ideologies of 2ª World War, Communism and Capitalism, and where a fight by this territory like political flag would be carried out? finally, the third approach talks about to the situation of two Coreas after the cold war locating the possible context of a possible reunification as well as scenes.

It was summarized previous works of the Al-in-hornblende geobarometer to quantify emplacement depths of the Cretaceous Bulgugsa granites and the Triassic-Jurassic Daebo granites in Korea. When calculated using the equation of Schmidt, the emplacement pressures of the Bulgugsa granites are less than 2.8 kb and those of the Daebo granites range from 3.4 to 7.8 kb. Assuming that the crustal thickness varies simply due to erosion and uplift, the crustal thickness of South Korea during the Jurassic can be calculated by adding average emplacement depth of the Jurassic granites to average thickness of present-day crust, which corresponds to about 50 km. The lower I terrace among the marine terraces had been formed in the Last Interglacial culmination stage(MIS 5e) by the amino-acid date, the identification of Ata tephra, the pollen assemblage and the relationships with the thalassostatic terrace of the Last Interglacial culmination stage, respectively. Ancient shoreline height of the lower marine terrace I is 18m on the whole southeastern coast of Korea. Therefore, if we assume that the sea level of the last Interglacial culmination period(125ka BP) was 6m higher than that of the present, the amount of net uplift since the last Interglacial culmination is about 12m, and if we suppose a constant-rate uplift, then the uplift rate in the southeastern coast area will be about 0.1m/ka

Abstract Postherpetic neuralgia (PHN) is a disease entity defined as persistent pain after the acute pain of herpes zoster gradually resolves. It is associated with impaired daily activities, resulting in reduced quality of life. General epidemiological data on PHN is necessary for the effective management. However, data on the epidemiology of PHN in Korea is lacking. The aim of this study was to evaluate the epidemiological features of PHN in the general population. We used population-based medical data for 51,448,491 subscribers to the Health Insurance Service in the year of 2013 to analyze of PHN epidemiology in Korea, such as the incidence, regional distribution, seasonal variation, and healthcare resource utilization. Total number of patients and medical cost on PHN were analyzed from 2009 to 2013. Findings indicate that the incidence of PHN in Korea was 2.5 per 1000 person-years, which was strongly correlated with age and sex. There were no differences in seasonal variation or regional distribution. The medical cost increased steadily over the study period. When admitted to general hospitals, patients with PHN were mainly managed in the dermatology and anesthesiology departments. The incidence and prevalence rates of PHN in Koreans appear to be considerably higher compared to those in western populations, while the sex and age predisposition was similar. Considering that the pain associated with PHN can have a marked impact on a patient's quality of life resulting in a medicosocial economic burden, anesthesiology physicians have an important role in primary care in Korea. Future research on the cost-effectiveness of the management of PHN is needed. PMID:27057902

Since 2011, the Republic of Korea (ROK) and United States (U.S.) have been collaborating to conduct inter- and intra-governmental exercises to jointly respond to biological events in Korea. These exercises highlight U.S. interest in increasing its global biosurveillance capability and the ROK's interest in improving cooperation among ministries to respond to crises. With Able Response (AR) exercises, the ROK and U.S. have improved coordination among US and ROK government and defense agencies responding to potential bio-threats and identified additional areas on which to apply refinements in policies and practices. In 2014, the AR exercise employed a Biosurveillance Portal (BSP) to facilitate more effective communication among participating agencies and countries including Australia. In the present paper, we seek to provide a comprehensive assessment of the AR 2014 (AR14) exercise and make recommendations for future improvements. Incorporating a more realistic response in future scenarios by integrating a tactical response episode in the exercise is recommended.

With the progress of computer technology, the applications of computer based safety systems in Korea nuclear power plants have increased rapidly in recent decades. The main purpose of this movement is to take advantage of modern computer technology so as to improve the operability and maintainability of the plants. However, in fact there have been a lot of controversies on computer based systems' safety between the regulatory body and nuclear utility in Korea. The Korea Institute of Nuclear Safety (KINS), technical support organization for nuclear plant licensing, is currently confronted with the pressure to set up well defined domestic regulatory requirements from this aspect. This paper presents the current status and the regulatory activities related to the applications of computer based safety systems in Korea. (author)

[Determinants of sterilization among married couples in Korea].

2007-11-01

The purpose of this study was to examine the determinants of sterilization in South Korea. This study was based on the data from the Korea National Fertility Survey carried out in the year 2000 by the Korea Institute of Health and Social Affairs. The subjects of the analysis were 4,604 women and their husbands who were in their first marriage, in the age group of 15-49 years. The data were analyzed by multiple logistic regression analysis. Consistent with the findings of previous studies, the woman's age and the number of total children increased the likelihood of sterilization. In addition, the year of marriage had a strong positive association with sterilization. Interestingly, the number of surviving sons tended to increase the likelihood of sterilization, whereas the woman's education level and age at the time of marriage showed a negative association with sterilization. Religion, place of residence, son preference, and the husband's education level, age and type of occupation were not significant determinants of sterilization. The sex of previous children and lower level of education are distinct determinants of sterilization among women in South Korea. More studies are needed in order to determine the associations between sterilization rate and decreased fertility.

North Korea, Quo Vadis?

Full Text Available North Korean politics appears neither irrational nor unpredictable: the logic of its actions may at first seem opaque, but it nonetheless displays its own rationale and patterns. – North Korea: a ruthless political actor, now under the leadership of Kim Jong-Un who inherited the regime’s leadership from his father and "Supreme Leader", Kim Jong-Il, in 2011. The country’s policy is based on its ongoing political agenda of (nuclear brinkmanship, a true threat to the world – or at least that's how the Western hemisphere sees it. Yet our factual knowledge of this post-Leninist and totalitarian regime is extremely limited and relatively distorted; it is largely circumstantial evidence and judgmental speculation that accounts for our perception of this East Asian state. Northeast Asia (China, Japan, South and North Korea, Taiwan is a region dominated by the legacy of the Cold War. The North Korean leadership has indeed established its priorities, primarily its isolationist orientation, but in the long term the regime cannot survive without external stimulus. Most importantly, even in a long-term, non-violent and gradual transformation of North Korea considerable danger can ultimately result in the demise of the regime. Apart from few signs of a North Korean "civil society", currently only the army might have the resources to see through a regime change. In the meantime, the strategies of isolationism as well as tight control of the media remain as fundamental cornerstones of the regime. A close-knit network of social control has been established and access to the internet for the most part is limited to the regime’s entrusted cadre.

The Huang-Huai-Hai Plain (HHH) is typical of China's farming area, and was predicted as one of the fastest growing areas of urbanization in the world. Since the turn of the new millennium, construction land and farmland transitions in this region driven by rapid urbanization have resulted in dramatic loss of farmland, which triggered a serious threat to regional even national food security. In this paper, the coupling relationships between per capita construction land transition (PCCT) and per capita farmland transition (PCFT) in the HHH and their implications for regional food security are analyzed. During 2000-2015, the farmland decreased by 8.59%, 72.25% of which were occupied by construction land. There are two major coupling types between PCCT and PCFT, one is the double increasing of per capita construction land area (PCCA) and per capita farmland area (PCFA); another is the increasing of PCCA and the decreasing of PCFA. The fluctuant increasing of PCCT and decreasing of PCFT coexisted and presented symmetrical coupling characteristics in space. Physical, location, transportation and socio-economic factors play significantly different roles in driving PCCT and PCFT. The implications for ensuring food security involve promoting the reclamation and redevelopment of inefficient and unused urban-rural construction land, reducing inefficient occupation of farmland resources, developing appropriate scale management of agriculture, and establishing a better social security system to smoothly settle down the floating rural population in the city.

The air quality of South Korea, located in the east of China, is affected by persistent westerlies, showing the relationship to the emission in upwind region. High aerosol concentration in South Korea is also attributed to local emissions. Particularly, the industrial complex and power plants are concentrated in the Chungcheongnam-do (CN), located by the southwest part of Seoul Metropolitan Area (SMA). In this study, we evaluate the contribution of both the transboundary transport of Chinese pollutants and local emissions in the CN to the air quality in South Korea during Korea-US Air Quality (KORUS-AQ) campaign, 1 May to 12 June in 2016. Based on the information of aerosol optical depth (AOD) obtained from ground-based Aerosol Robotic NETwork (AERONET) sunphotometer and surface in-situ Particulate Matter (PM) measurements at 19 stations, high and low aerosol pollution cases are classified first. Then, 2-day back-trajectories are calculated using National Ocean and Atmospheric Administration (NOAA) HYbrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model at each AERONET site to investigate whether transport pattern is different in accordance with the classified cases about aerosol amounts. As a result, we find the distinct pathway of air-mass transport from eastern China; When high AOD is observed at station located in the western coast of South Korea, air masses are directly transported from Shandong peninsular to the Korean peninsula. In contrast, air masses are mostly transported from northwestern or northern China during the period of low AOD conditions. When PM2.5 detected at SMA sites is greater than Korean government criteria (50 micrograms per cubic meter for 24-hour average PM2.5), SMA sites are mostly affected by air mass flows through the CN area. These results indicate that transport pattern can be different vertically and surface aerosol concentration has different transport pattern from the transport pattern related to the variation of

A neighborhood-level analysis of mortality from suicide would be informative in developing targeted approaches to reducing suicide. This study aims to examine the association of community characteristics with suicide in the 424 neighborhoods of Seoul, South Korea. Neighborhood-level mortality and population data (2005-2011) were obtained to calculate age-standardized suicide rates. Eight community characteristics and their associated deprivation index were employed as determinants of suicide rates. The Bayesian hierarchical model with mixed effects for neighborhoods was used to fit age-standardized suicide rates and other covariates with consideration of spatial correlations. Suicide rates for 424 neighborhoods were between 7.32 and 71.09 per 100,000. Ninety-nine percent of 424 neighborhoods recorded greater suicide rates than the Organization for Economic Cooperation and Development member countries' average. A stepwise relationship between area deprivation and suicide was found. Neighborhood-level indicators for lack of social support (residents living alone and the divorced or separated) and socioeconomic disadvantages (low educational attainment) were positively associated with suicide mortality after controlling for other covariates. Finding from this study could be used to identify priority areas and to develop community-based programs for preventing suicide in Seoul, South Korea.

Korea has selected nuclear energy as the major source for the electric power generation due to the insufficiency of energy resources in Korea. in compliance with the policy, Korea Electric Power Corporation (KEPCO) has expanded the nuclear power programme and faced the significant arisings of spent fuel. The interim At Reactor(AR) storage pools have very limited capacities and temporary expansion of this capacity has been taken such as re-racking and dry storage construction. There was a plan, to construct a centralized spent fuel storage facility, which was postponed officially by the government. Under the current situation, it is hard to establish the long-term spent fuel management strategy. 'Wait and See' is no more applicable to Korea. because of storage shortage. Within R and D, dry storage construction and DUPIC fuel cycle are being considered. In this paper, the spent fuel management programme of Korea is briefly reviewed. (author)

2006-01-01

In Korea, 20 nuclear power plants are in operation and lots of spent fuels are on the onsite storage. The onsite storage capacity in Korea is supposed to be full around at the year of 2016 and interim storage facilities could be considered to be constructed before 2016. A review framework to evaluate the radiation shielding safety of the interim storage facilities is developed in this study. It includes acceptance criteria, review procedures and activities of independent analyses. A case study is performed to apply the review framework. Modeling the review reference storage, evaluating the source terms and calculating the photon fluxes are performed. It is shown that the application of the review framework could satisfy the regulatory demand that would arise in the near future in the review area of the radiation shielding safety of the interim storage in Korea.

Dowhaniuk, Nicholas; Hartter, Joel; Ryan, Sadie J

2014-09-01

Geographic information systems and remote sensing technologies have become an important tool for visualizing conservation management and developing solutions to problems associated with conservation. When multiple organizations separately develop spatial data representations of protected areas, implicit error arises due to variation between data sets. We used boundary data produced by three conservation organizations (International Union for the Conservation of Nature, World Resource Institute, and Uganda Wildlife Authority), for seven Ugandan parks, to study variation in the size represented and the location of boundaries. We found variation in the extent of overlapping total area encompassed by the three data sources, ranging from miniscule (0.4 %) differences to quite large ones (9.0 %). To underscore how protected area boundary discrepancies may have implications to protected area management, we used a landcover classification, defining crop, shrub, forest, savanna, and grassland. The total area in the different landcover classes varied most in smaller protected areas (those less than 329 km(2)), with forest and cropland area estimates varying up to 65 %. The discrepancies introduced by boundary errors could, in this hypothetical case, generate erroneous findings and could have a significant impact on conservation, such as local-scale management for encroachment and larger-scale assessments of deforestation.

In South Korea, scrub typhus is the most common acute febrile illness in autumn. We analyzed scrub typhus cases reported from 2008 to 2012 to describe the epidemiology of scrub typhus as well as eschar patterns. A total of 30,478 cases were reported from 2008 to 2012; the incidence rates were higher in the southern and western regions of South Korea. The common clinical symptoms of confirmed scrub typhus cases from 2010 to 2012 were fever/chills (95.2%), eschars (78.9%), and myalgia (61.7%). The primary sites of eschars were the lower extremities (19.0%), abdomen/waist (13.4%), and axilla (11.5%) in men and the shoulder/frontal chest (15.1%), lower extremities (14.5%), and abdomen/waist (13.6%) in women. Regardless of gender, eschars tended to be more on the lower extremities among the leisure activities group. Among the occupational farm work group, who usually lived in rural areas, eschars appeared most frequently on the abdomen/waist in men and on the shoulder/frontal chest in women. Eschar patterns were influenced by gender and activities. These results could facilitate the prevention of scrub typhus and clarify the current status of scrub typhus in South Korea.

Monitoring and time-series analysis of the hydrological parameters electrical conductivity (EC), water pressure, precipitation and tide were carried out, to understand the characteristics of the parameter variations and their correlations at a coastal area in Busan, South Korea. The monitoring data were collected at a sharp interface between freshwater and saline water at the depth of 25 m below ground. Two well-logging profiles showed that seawater intrusion has largely expanded (progressed inland), and has greatly affected the groundwater quality in a coastal aquifer of tuffaceous sedimentary rock over a 9-year period. According to the time series analyses, the periodograms of the hydrological parameters present very similar trends to the power spectral densities (PSD) of the hydrological parameters. Autocorrelation functions (ACF) and partial autocorrelation functions (PACF) of the hydrological parameters were produced to evaluate their self-correlations. The ACFs of all hydrologic parameters showed very good correlation over the entire time lag, but the PACF revealed that the correlations were good only at time lag 1. Crosscorrelation functions (CCF) were used to evaluate the correlations between the hydrological parameters and the characteristics of seawater intrusion in the coastal aquifer system. The CCFs showed that EC had a close relationship with water pressure and precipitation rather than tide. The CCFs of water pressure with tide and precipitation were in inverse proportion, and the CCF of water pressure with precipitation was larger than that with tide.

Metal contamination from mining activity is of great concern because of potential health risks to the local inhabitants. In the present study, we investigated the levels of Cd, Cu, As, Pb, and Zn in environmental samples and foodstuffs grown in the vicinity of the mines in Goseong, Korea, and evaluated potential health risks among local residents. Soils near the mines exceeded the soil quality standard values of Cu, As, and Zn contamination. The concentrations of Cd, Cu, Pb, and Zn in crop samples collected from the study area were significantly higher than those of the reference area. Some rice samples collected from the study area exceeded the maximum permissible level of 0.2 mg Cd/kg. The intake of rice was identified as a major contributor (≥75%) to the estimated daily intake among the residents. The average estimated daily intakes of metals were, however, below the provisional tolerable daily intake. -- Highlights: •Area near the abandoned mines was significantly contaminated with metals. •Some rice grains exceeded the maximum permissible level of Cd. •The estimated daily intake of metals was below the provisional tolerable daily intake. •Intake of rice was constituted the major proportion of estimated daily intake. -- Cadmium was detected relatively high in rice, and was identified as a chemical of potential concern in an area near abandoned copper mines of Goseong, Korea

This paper examines the motivations, processes and outcomes of the development of smart grids in South Korea through the perspectives of governance and innovation systems. Drawing on desktop research and semi-structured interviews, this paper has two major findings. First, the development of smart grids in Korea has been shaped by various factors including macroeconomic policy, the role of the government, and experimentation. The complex interactions between these factors at the landscape, regime and niche levels has impacted on the development of smart grids. Second, while Korea's government-led approach has its strengths in driving change, it has also exposed weaknesses in the country's ability to mobilise the private sector and consumer participation. Major obstacles including partial electricity market reform and public distrust exist. A systemic perspective is needed for policy in order to accommodate the changes required for smart grid development. Regulatory reforms, particularly price-setting mechanisms, and consumer engagement are priority areas for policy change. - Highlights: ► Smart grid developments in Korea have been affected by factors that go beyond technological ones. ► Those factors include macroeconomic policy, government's role, and experimentations. ► These factors also interacted at the landscape, regime and niche levels. ► The government-led approach has limitations in engaging the private sector and consumers. ► Major constrains include partial electricity market reform and public distrust.

This study has identified the gaps in the safety requirements for design of research reactors of Korea comparing with those of the IAEA. The review results showed that the gaps have arisen mainly from the following aspects: - The differences in the characteristics of design and operation between power reactor and research reactor - Enhancement of the level of safety of nuclear reactor facility - Consideration of advanced safety technologies. The review results will be utilized to reflect the IAEA safety requirements for design of research reactors into those of Korea, which will contribute to enhancing the level of safety and improving the technical standards of research reactors of Korea. The IAEA safety standards encompass international consensus to strengthen the nuclear safety and to reflect the latest advancement of nuclear safety technologies. Also, they provide reliable means to ensure the effective fulfillment of obligations under the various international safety conventions. Many countries have adopted the IAEA safety standards as their national standards in nuclear regulations. Since Korea has exported research reactor technologies abroad these days and will continue to export them in the future, it is desirable to harmonize domestic safety requirements for research reactor with those of the IAEA. The KINS (Korea Institute of Nuclear Safety) has performed a review of the IAEA safety requirements for design of research reactors comparing with those of Korea. The purpose of this comparative study is to harmonize the safety requirements for the design of research reactors of Korea with those of the IAEA as a member state of the IAEA, and to encompass global efforts to enhance the nuclear safety and to reflect the latest advancement of nuclear safety technologies into the safety requirements for the design of research reactors of Korea. Design requirements for structures, systems, and components of research reactors important to safety, which are required to

Studying human health in areas with industrial contamination is a serious and complex issue. In recent years, attention has increasingly focused on the health implications of large industrial complexes. A variety of potential toxic chemicals have been produced during manufacturing processes and activities in industrial complexes in South Korea. A large number of dyeing industries gathered together in Daegu dyeing industrial complex. The residents near the industrial complex could be often exposed to volatile organic compounds. This study aimed to evaluate VOCs levels in the ambient air of DDIC, to assess the impact on human health risks, and to find more convincing evidences to prove these VOCs emitted from DDIC. According to deterministic risk assessment, inhalation was the most important route. Residential indoor, outdoor and personal exposure air VOCs were measured by passive samplers in exposed area and controlled area in different seasons. Satisfaction with ambient environments and self-reported diseases were also obtained by questionnaire survey. The VOCs concentrations in exposed area and controlled area was compared by t-test. The relationships among every VOC were tested by correlation. The values of hazard quotient (HQ) and life cancer risk were estimated. The concentrations of measured VOCs were presented, moreover, the variety of concentrations according the distances from the residential settings to the industrial complex site in exposed area. The residential indoor, outdoor, and personal exposure concentrations of toluene, DMF and chloroform in exposed area were significantly higher than the corresponding concentrations in controlled area both in summer and autumn. Toluene, DMF, chloroform and MEK had significantly positive correlations with each other in indoor and outdoor, and even in personal exposure. The HQ for DMF exceeded 1, and the life cancer risk of chloroform was greater than 10 - 4 in exposed area. The prevalence of respiratory diseases

The geochemistry and environmental isotopes of groundwater in the Cretaceous granite of the Yeongcheon area has been investigated. The hydrochemistry of groundwater belongs to the Ca-HCO 3 type. The oxygen-18 and deuterium data are clustered along the meteoric water line, indicating that the groundwater is of meteoric water origin. Tritium data show that the groundwaters were mostly recharged before pre-thermonuclear period and have been mixed with younger surface water flowing rapidly along fractured zones. Based on the mass balance and reaction simulation approaches using both the hydrochemistry of groundwater and the secondary mineralogy of fracture-filling materials, the low-temperature hydrogeochemical evolution of groundwater in the area has been modeled. The results of geochemical simulation show that the concentrations of Ca, Na and HCO 3 and pH of waters increase progressively owing to the dissolution of reactive minerals in flow paths. The concentrations of Mg and K first increase with the dissolution of reactant minerals, but later decrease when montmorillonite and illitic material are precipitated respectively. The continuous adding of reactive minerals, i. e. the progressively larger degrees of water/rock interaction, causes the formation of secondary minerals with the following sequence: hematite > gibbsite > kaolinite > montmorillonite > illitic material > microcline. The results of reaction simulation agree well with the observed water chemistry and secondary mineralogy, indicating the successful applicability of this simulation technique to delineate the complex hydrogeochemistry of bedrock groundwaters.

PCDDs and PCDFs are detected routinely, as they are widely distributed in the environment and accumulate in the food chain. Moreover, because human beings are at the top of food chain, a relatively high level of these compounds can be found in human adipose tissues, blood lipids, and breast milk fat. In Korea, the number of municipal and hazardous waste incinerators have increased since 1980. In addition, municipal waste incinerators are almost always located in residential areas. Therefore, the human health risks caused by dioxin is become an increasing public concern in Korea. The aim of this study was to determine the concentrations of PCDDs/PCDFs in blood from individuals living in the vicinity area of the municipal solid waste incinerator (MSWI), and to compare PCDDs/PCDFs levels in blood for residents living near the MSWI, workers at the MSWI and general population living in the urban area not including the MSWI. Analysis of the results was made in terms of sociodemographic characteristics such as age, sex, smoking habit, food consumption patters, and proximity to the MSWI.

[Preventive measures against plague and the control of Chinese coolies in colonial Korea].

Kim, Youngsoo

2014-12-01

This paper aims to examine the preventive measures taken against the plague in colonial Korea, particularly as applied to the control of Chinese coolies in 1911, soon after the annexation. The Government General of Korea began preventive measures with a train quarantine in Shin'uiju and Incheon in response to the spread of the plague to the Southern Manchuria. Shin' uiju had become urbanized due the development of the transportation network, and the seaport of Incheon was the major hub for traffic with China. Examining the transportation routes for the entry and exit of Chinese to and from Korea makes clear the reason why the Korea Government General initiated preventive measures in mid-January, 1911. The Government General of Korea tried to block the entry of Chinese through the land border crossing with China and through ports of entry, primarily Incheon. During the implementation of the preventive measures, quarantine facilities were built, including a quarantine station and isolation facility in Incheon. It was also needed to investigate the population and residential locations of Chinese in Korea to prevent the spread of plague. A certificate of residence was issued to all Chinese in Korea, which they needed to carry when they travelled. The preventive measures against plague which broke out in Manchuria were removed gradually. However, there was no specific measures against Chinese coolies, those who had migrated from China to work in the spring in Korea. Still the Government General of Korea had doubt about an infection of the respiratory system. As a result, the labor market in colonial Korea underwent changes in this period. The Government General recruited Korean laborers, instead of Chinese coolies whose employment had been planned. This move explains the Government General's strong preventive measures against plague and uncertainty in the route of plague infection, which influenced subsequent regulations on the prohibition of Chinese coolies working on

TRIGA Mark-II, the first research reactor in Korea, has operated since 1962, and the second one, TRIGA Mark-III since 1972. Both of them had their operation phased out in 1995 due to their lives and operation of the new research reactor, HANARO (High-flux Advanced Neutron Application Reactor) at the Korea Atomic Energy Institute (KAERI) in Taejon. Decontamination and decommissioning (D and D) project of TRIGA Mark-II and Mark-III was started in January 1997 and will be completed in December 2002. The first year of the project, work was performed in preparation of the decommissioning plan, start of the environmental impact assessment and setup licensing procedure and documentation for the project with cooperation of Korea Institute of Nuclear Safety (KINS). Hyundai Engineering Company (HEC) is the main contractor to do design and licensing documentation for the D and D of both reactors. British Nuclear Fuels plc (BNFL) is the technical assisting partner of HEC. The decommissioning plan document was submitted to the Ministry of Since and Technology (MOST) for the decommissioning license in December 1998, and it expecting to be issued a license in mid 1999. The goal of this project is to release the reactor site and buildings as an unrestricted area. This paper summarizes current status and future plan for the D and D project. (author)

The Republic of Korea is in the process of preparing for its first ever vitrification plant to handle low and intermediate-level radioactive waste from her pressurized water reactors (PWRs). KEPRI, in coordination with her partners, will design, construct, and erect a pilot plant using data from the orientation tests. The pilot plant will be the basis for the development of the final objective, the establishment of an industrial scale vitrification installation in the Republic of Korea. Throughout these projects, the major goal is to minimize the harmful effects of the final waste form to the environment. The gaseous effluents emissions from the facility will need to be managed to meet the environmental regulations concerning gaseous releases into the environment of the Republic of Korea. The focus of this paper is on the considerations for the treatment of the off-gas for a low and intermediate-level radioactive waste treatment vitrification installation in the Republic of Korea. Off-gas considerations will span a wide-range of areas such as waste characteristics, thermal treatment systems, off-gas regulations, off-gas characteristics, assessment of air pollution control devices, systems assessments, numerical modelling, economics etc. Off-gas regulations in Korea are becoming tighter and will likely change from year to year. In terms of both off-gas treatment equipment performance and public protection, the amount and nature (e.g. chemical behavior and morphology) of the species are important. The emissions may be classified as toxic metals, radionuclides, hydrocarbons, particulate matter, and acid gases. Air pollution control technologies are generally classified as wet or dry technologies covering over 40 different air pollution control devices (APCDs) with varying removal efficiencies for the different types of off-gas. In general, the state of the art systems for vitrification technologies incorporate the basic functions such as further oxidation of products

Untuk mengulas hal tersebut, artikel ini memfokuskan diri pada telaah historis masa pendudukan Jepang, yakni pada rentang waktu antara tahun 1910 hingga 1945. ArikelArtikel ini berusaha untuk menjawab pertanyaan sederhana: mengapa Kristen Protestan berhasil menjadi agama yang kuat dan penting di Korea? Jawaban atas pertanyaan tersebut juga akan mengantarkan kita untuk bisa memahami nasionalisme Korea. Dengan kata lain, jelas bahwa perkembangan Protestan di Korea adalah sangat terkait dengan ketidakpuasan yang mendalam dan keputusasaan yang dirasakan oleh orang-orang Korea diakibatkan oleh masa pendudukan Jepang. Selain dikarenakan faktor nasionalisme, berkembangnya agama Protestan di Korea juga sangat terkait dengan pendidikan. Para misionaris bertindak cepat untuk melibatkan diri dalam pendidikan. Hal tersebut dikarenakan mereka memahami tentang semangat Korea dalam hal pendidikan dan juga keterbukaan mereka terhadap ide-ide Barat. Selain itu, artikel ini juga mengkaji mengenai dampak dari adanya para missionarismisionaris untuk menyebarkan agama protestanProtestan. Salah satunya adalah dalam hal ekonomi.

Faced with aging societies, there is an immense need to better understand the nature of volunteering outside advanced Western industrial countries. As a case of a rapidly aging society, we identify robust factors associated with elderly volunteering in Korea in terms of a resource framework. Data were derived from the Social Statistics Survey conducted by the Korea National Statistical Office in 1999 (N = 7,135) and 2003 (N = 8,371). We first determined overall and age-related volunteer rates for Korea compared to the United States. Using logistic regression, we then examined the effects of human, cultural, and social capital variables on volunteering. Approximately 6% of Koreans aged 65 years and older participate in volunteer programs. All human capital variables are positively related with volunteering. For cultural capital, those who identify their religion as Buddhism or Catholicism are more likely to volunteer than those who have no religion. But surprisingly, Protestantism does not consistently promote volunteering across both years. For social capital, older adults who live alone or with a spouse are more likely to volunteer than those living with both a spouse and children. In contrast to human capital, cultural and social capital on elderly volunteering appears to be contoured by social contexts.

2012-01-01

Objectives Over the past several years, the incidence of hepatitis A infection has been increasing rapidly in the young-adult population in Korea. We examined the effects of area-level socioeconomic status and environmental hygiene on the incidence of hepatitis A. Methods This study is based on the registered national population of Korea and the national health insurance data from 2004 to 2008. A total of 73 459 individuals were confirmed to have had hepatitis A. The standardized incidences of hepatitis A in 232 districts adjusted for sex and age of people were calculated for each year, and the rate ratios of the incidence rates were estimated according to area-level socioeconomic status and environmental hygiene using multiple Poisson regression models. Results The incidence rates of hepatitis A infection were 15.6 (per 100 000) in 2004, 19.0 (per 100 000) in 2005, 27.2 (per 100 000) in 2006, 25.1 (per 100 000) in 2007, and 61.7 (per 100 000) in 2008. The analysis of the area-level effects showed that residential areas of the less deprived than other regions, areas with higher levels of education, and heavily populated areas were significantly associated with increased risk. Conclusions There is a very strong possibility that both area-level socioeconomic status and environmental hygiene play a role in increasing the risk of hepatitis A infection in Korea. Therefore, to reduce hepatitis A infection, we need a nationwide strategy that considers these area-level characteristics. PMID:22712043

Chung, W.J. [Korea Energy Economics Institute, Euiwang (Korea)

2001-12-01

The economy of North Korea has fallen into the trap of poverty. One of the reasons is diagnosed at the study that the marginal productions in the economy have diminished due to the past economic extensions without technology developments. The other is that industry productions have been decreased due to the downward spirals for the chains of industry, which came mainly from the restrictions of supply in the overseas dependent energy industry and core parts of heavy industry as the North Korea's relations with the foreign countries became worse. On the assumption that the North Korea makes efforts to develop its economy on a big push-style, this study projected the GDP growth rates and the changes of industry structure in two decades at the scenarios of 'with opening and reforming' and 'with only reforming', 'without opening and reforming' in North Korea. Energy demands by types and industries were then forecasted with the projected GDP growth rates and industry structures at the study. Various concepts over the energy are raised in a relationship of two Koreas. Energy can become economic good for the investment and trade for the mutual benefit or the support goods for humanity like foods and medical supplies, strategical goods for military purposes. On the other hand, energy part would be a leading industry for economic growth in the North and the active and large scale economic cooperation between two Koreas. Though it is reasonable that the energy are invested and traded on a commercial basis between two Koreas, the historical and political properties force the South to support energy to the North as an urgent measure not only for the North Korea's escape from the economic crisis, but for attaining the various political and social purposes between two Koreas. The study on the energy business between two Koreas began with analysing the ways of the South's investments to the energy facilities in North Korea for the

The purpose of this study was to record, analyze, and identify ethnopharmacological implications for oral traditional knowledge regarding the medicinal use of animals by indigenous people living in Wolchulsan National Park, Korea. Data were collected through interviews, informal meetings, open and group discussions, and observations guided by semi-structured questionnaires. Data were analyzed via quantitative analysis of informant consensus factor and fidelity level, and network analysis, including centrality and clustering analysis. A total of 46 families, 59 genera, and 60 species of animals, as well as 373 methods of usage, were recorded. Fish comprised 31.7% of the total animal species recorded, followed by mammals at 20.0%, arthropods at 18.3%, and mollusks at 11.7%. Of these animals, 48.0% were utilized as food and 46.1% for medicinal use. Quantitative analysis showed that the category with the highest degree of consensus from informants was veterinary ailments (informant consensus factor value, 0.96). This was followed by poisonings (0.93), pains (0.92), genitourinary system disorders (0.91), cuts and wounds (0.89), and other medical conditions. The lowest degree of consensus was for skin diseases and disorders (0.57). There were 8 species of animals with a fidelity level of 100%, after eliminating from the animals analyzed that were mentioned only once. Finally, using network analysis, Gallus gallus domesticus and Gloydius brevicaudus were defined as species with meaningful medicinal use, while lack of vigor and lung diseases were defined as significant ailments in the study area. This study validates that local communities use animals not only for food but also for medicinal purposes as crucial therapeutic measures. Therefore, the conservation of fauna and preservation of traditional knowledge need to be seriously considered to maintain the health and well-being of the local communities. Network analysis clarified the series of ailments for which each

Older people are a major vulnerable population. During disasters, given their physical frailty, lower social status, loss of medications and medical care, the vulnerability of older people increases. The purpose of this study was to examine the perceptions of older people in Korea on various aspects of disaster preparedness to better understand their special needs and to facilitate appropriate disaster planning. The study was qualitative and used focus group interviews with 12 older people in one major city and one rural area of South Korea. Four themes were identified by the analysis of the interviews: defenceless state, reality of accepting limitations, strong will to live, importance of disaster preparedness governmental efforts for the older people. Findings indicated that preparation of shelters and transportation was critical to help older people survive in times of disasters and suggested that there should be active involvement of the government in terms of disaster planning, managing and preparing older people for disasters. In addition, healthy older people can be assets to disaster relief efforts by providing practical and emotional support for the most fragile older people. Older people can also provide knowledge of their special needs to the government to improve their disaster response policy. © 2015 John Wiley & Sons Ltd.

Comparative research on health outcomes in North and South Korea offers a unique opportunity to explore political and social determinants of health. We examined the age- and cause-specific contributions to the life expectancy (LE) gap between the two Koreas. We calculated the LE at birth in 1993 and 2008 among North and South Koreans, and cause-specific contributions to the LE discrepancy between the two Koreas in 2008. The cause-specific mortality data from South Korea were used as proxies for the cause-specific mortality data in North Korea in 2008. The LE gap between the two Koreas was approximately 1 year in 1993, but grew to approximately 10 years in 2008. This discrepancy was attributable to increased gaps in mortality among children younger than 1 year and adults 55 years of age or older. The major causes of the increased LE gap were circulatory diseases, digestive diseases, infant mortality, external causes, cancers and infectious diseases. This study underscores the urgency of South Korean and international humanitarian aid programs to reduce the mortality rate of the North Korean people.

Natural beach is controlled by many factors related to wave and tidal forces, wind, sediment, and initial topography. For this reason, if numerous topographic data of beach is accurately collected, coastal erosion/acceleration is able to be assessed and clarified. Generally, however, many studies on coastal erosion have limitation to analyse the whole beach, carried out of partial area as like shoreline (horizontal 2D) and beach profile (vertical 2D) on account of limitation of numerical simulation. This is an important application for prevention of coastal erosion, and UAV photogrammetry is also used to 3D topographic data. This paper analyses the use of unmanned aerial vehicles (UAV) to 3D map and beach volume change. UAV (Quadcopter) equipped with a non-metric camera was used to acquire images in Songjung beach which is located south-east Korea peninsula. The dynamics of beach topography, its geometric properties and estimates of eroded and deposited sand volumes were determined by combining elevation data with quarterly RTK-VRS measurements. To explore the new possibilities for assessment of coastal change we have developed a methodology for 3D analysis of coastal topography evolution based on existing high resolution elevation data combined with low coast, UAV and on-ground RTK-VRS surveys. DSMs were obtained by stereo-matching using Agisoft Photoscan. Using GCPs the vertical accuracy of the DSMs was found to be 10 cm or better. The resulting datasets were integrated in a local coordinates and the method proved to be a very useful fool for the detection of areas where coastal erosion occurs and for the quantification of beach change. The value of such analysis is illustrated by applications to coastal of South Korea sites that face significant management challenges.

Changes in lifestyle including obesity epidemic and reduced physical activity influenced greatly to increase the cancer burden in Korea. The purpose of the current study was to perform a systematic assessment of cancers attributable to obesity and physical inactivity in Korea. Gender- and cancer site-specific population-attributable fractions (PAF) were estimated using the prevalence of overweight and obesity in 1992-1995 from a large-scale prospective cohort study, the prevalence of low physical activity in 1989 from a Korean National Health Examination Survey, and pooled relative risk estimates from Korean epidemiological studies. The overall PAF was then estimated using 2009 national cancer incidence data from the Korea Central Cancer Registry. Excess body weight was responsible for 1,444 (1.5%) and 2,004 (2.2%) cancer cases among men and women, respectively, in 2009 in Korea. Among men, 6.8% of colorectal, 2.9% of pancreatic, and 16.0% of kidney cancer was attributable to excess body weight. In women, 6.6% of colorectal, 3.9% of pancreatic, 18.7% of kidney, 8.2% of postmenopausal breast, and 32.7% of endometrial cancer was attributable to excess body weight. Low leisure-time physical activity accounted for 8.8% of breast cancer, whereas the PAF for overall cancer was low (0.1% in men, 1.4% in women). Projections suggest that cancers attributable to obesity will increase by 40% in men and 16% in women by 2020. With a significantly increasing overweight and physically inactive population, and increasing incidence of breast and colorectal cancers, Korea faces a large cancer burden attributable to these risk factors. Had the obese population of Korea remained stable, a large portion of obesity-related cancers could have been avoided. Efficient cancer prevention programs that aim to reduce obesity- and physical inactivity-related health problems are essential in Korea.

This study explores the impact of adolescent part-time work experience on problem behaviors in the South Korean context. To achieve this, propensity score matching (PSM) analyses were employed based on data from the Korean Education Employment Panel (KEEP). Results indicate that adolescents' part-time employment during their secondary school years had significantly undesirable effects on drinking and smoking, even after preexisting differences between the two groups (i.e., those adolescents who participated in part-time work and those who did not) were controlled by PSM. However, an insignificant difference was detected in the likelihood of running away from home. Implications of the results are discussed in terms of changes in the meanings of adolescence and of participating in part-time work in South Korea. © 2016 The Authors.

2007-01-01

Currently in Korea, 20 nuclear plants are in operation, generating some 18,000 MWe of electricity which is about 30% of the national electricity supply. Further 8 reactors, including innovative light water reactors developed with 30 years' experience in construction and operation with continuous technology development, are either under construction or being planned. Executing an energetic program of nuclear development, Korea is now the world's sixth-ranked nuclear nation. In this paper, at first, history of the nuclear reactor development in Korea will be discussed including technology self-reliance efforts of the nuclear industry, and future plan and prospects will also be presented. Secondly, the OPR1000 which is a Korean standard plant will be introduced in detail including its characteristics, design approach and features. Six OPR1000's are being operated with outstanding performance and 4 more units are under construction. The APR1400, an upgraded reactor of the OPR1000 in capacity and design, has been developed as a next generation reactor, and the contracts were signed for the first 2 units' construction in August 2006. Its development process and design features will be described. Finally, Korea's efforts for future nuclear power generation will be introduced. For future reliable energy supply, Korea has been actively participating in international cooperation such as Gen IV International Forum. In summary, this paper will introduce the history and status of the Korean nuclear reactor development with its past, present and future, which might be helpful to understand the Korean nuclear industry and find a way for international cooperation especially with European countries

To evaluate scientific papers published by Korean radiologists in the Science Citation Index Expanded (SCIE) radiology journals, between 1986 and 2010. The Institute for Scientific Information Web of Knowledge-Web of Science (SCIE) database was searched for all articles published by Korean radiologists, in SCIE radiology journals, between 1986 and 2010. We performed the analysis by typing 'Korea' and 'radiol' in the address section and selecting the subject area of 'Radiology, Nuclear Medicine, and Medical Imaging' with the use of the general search function of the software. Analyzed parameters included the total number of publications, document types, journals, and institutions. In addition, we analyzed where Korea ranks, compared to other countries, in terms of the number of published articles. All these data were analyzed according to five time periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. Overall, 4974 papers were published by Korean radiologists, in 99 different SCIE journals, between 1986 and 2010, of which 4237 (85.2%) were article-type papers. Of the total 115395 articles, worldwide, published in radiology journals, Korea's share was 3.7%, with an upward trend over time (p < 0.005). The journal with the highest number of articles was the American Journal of Roentgenology (n 565, 13.3%). The institution which produced the highest number of publications was Seoul National University (n = 932, 22.0%). The number of scientific articles published by Korean radiologists in the SCIE radiology journals has increased significantly between 1986 and 2010. Korea was ranked 4th among countries contributing to radiology research during the last 5 years.

The influence of industrial and/or municipal contaminant inputs on the aquatic environment of Pohang, Korea was investigated, with a focus on bioassay combined with instrumental analysis. Pohang is the most heavily populated city in Gyeongsangbuk-do province of Korea, with more than half a million residents, and also hosts the nation's biggest steel manufacturer and related industries. Sediment (n=15) and surface water samples (n=17) were collected from Hyeongsan River which runs across the Pohang city, in two separate events, i.e., June 2010 and February 2011. Sediment samples were first Soxhlet-extracted (raw extract) and were measured for estrogenicity using H295R cell line, and also analyzed for alkylphenols (APs), bisphenol A (BPA), PAHs, and PCBs. For sediment samples which exhibited greatest effects in the cell line, further fractionation was performed into non-polar, mid-polar, and polar portions. In surface water samples, heavy metals were also analyzed. Among 15 sediment samples, station S2 near the steel industry complex and station M3 near the municipal area showed the greatest sex hormone changes, and these changes were generally explained by the fractions which contained APs and BPA. Principal component analysis (PCA) however suggests that chemicals that were not analyzed in the present study would better explain endocrine disruption capacity of sediments. In water samples, adverse effects on hatchability and growth of Japanese medaka fish, and on Daphnia reproduction were noted following exposure to six water samples collected from stations near industrial and municipal areas. Several heavy metals and nonylphenol (NP) concentrations exceeded surface water quality guidelines, suggesting adverse effects of contamination inputs from both industrial and municipal activities. Observed estrogenicities in stations such as S2 and M3 warrant further investigations on longer term ecosystem impacts near industrial and municipal areas. The levels of major

Full Text Available Previously only one species, Embolemus ruddii Westwood, 1833, of the family Embolemidae has been recorded in South Korea. As part of a recent study of this family, we newly report four species from South Korea: Embolemus hachijoensis Hirashima et Yamagishi, 1975; E. krombeini Olmi, 1996; E. sensitivus Xu, Olmi et Guglielmino, 2012; Ampulicomorpha thauma Rasnitsyn et Matveev, 1989. The genus, Ampulicomorpha Ashmead, 1893, is recorded for the first time in South Korea. Embolemus ruddii was previously recorded from South Korea because considered synonym of E. walkeri. However, in recent years the two species were separated and E. ruddii was considered absent in the far east, where on the contrary E. walkeri is present. Therefore, five species in two genera are now recognized as the South Korean embolemid fauna. A key to the South Korean Embolemidae species is provided.

2016-04-01

In collaboration with the Targeted Ultrasound Initiative (TUI), to conduct the first study in Korea to investigate current practices in ultrasound use among Korean rheumatologists. We translated the TUI Global Survey into Korean and added questions to better understand the specific challenges facing rheumatologists in Korea. To target as many rheumatologists in Korea as possible, we created an on-line version of this survey, which was conducted from March to April 2013. Rheumatologists are in charge of ultrasound in many Korean hospitals. Rheumatologists in hospitals and private clinics use ultrasound to examine between one and five patients daily; they use ultrasound for diagnosis more than monitoring and receive compensation of about US$30-50 per patient. There are marked differences in the rates of ultrasound usage between rheumatologists who work in private practice compared with tertiary hospitals. Korean rheumatologists not currently using ultrasound in their practice appear eager to do so. This survey provides important insights into the current status of ultrasound in rheumatology in Korea and highlights several priorities; specifically, greater provision of formal training, standardization of reporting and accrual of greater experience among ultrasound users. If these needs are addressed, all rheumatology departments in Korea are likely to use ultrasound or have access to it in the future. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Fasciola hepatica is a trematode that causes zoonosis, mainly in cattle and sheep, and occasionally in humans. Few recent studies have determined the infection status of this fluke in Korea. In August 2015, we collected 402 samples of freshwater snails at Hoenggye-ri (upper stream) and Suha-ri (lower stream) of Song-cheon (stream) in Daegwalnyeong-myeon, Pyeongchang-gun in Gangwon-do (Province) near many large cattle or sheep farms. F. hepatica infection was determined using PCR on the nuclear ribosomal internal transcribed spacer 2 (ITS-2). Among the 402 samples, F. hepatica 1TS-2 marker was detected in 6 freshwater snails; thus, the overall prevalence in freshwater snails was 1.5%. The prevalence varied between collection areas, ranging from 0.0% at Hoenggye-ri to 2.9% at Suha-ri. However, F. gigantica ITS-2 was not detected in the 6 F. hepatica -positive samples by PCR. The nucleotide sequences of the 6 F. hepatica ITS-2 PCR-positive samples were 99.4% identical to the F. hepatica ITS-2 sequences in GenBank, whereas they were 98.4% similar to F. gigantica ITS-2 sequences. These results indicated that the prevalence of F. hepatica in snail intermediate hosts was 1.5% in Gangwon-do, Korea; however the prevalence varied between collection areas. These results may help us to understand F. hepatica infection status in natural environments.

The drinking water network serving Korea has been used for almost 100 years. Therefore, pipelines have suffered various degrees of deterioration due to aggressive environments. The pipe breaks were caused by in-external corrosion, water hammer, surface loading, etc. In this paper, we focused on describing corrosion status in water distribution pipes in Korea and reviewing some methods to predict corrosion rates. Results indicate that corrosive water of lakes was more aggressive than river water and the winter was more aggressive compared to other seasons. The roughness growth rates of Dongbok lake showed 0.23 mm/year. The high variation of corrosion rates is controlled by the aging pipes and smaller diameter. Also the phenolphthalein test on a cementitious core of cement mortar lined ductile cast iron pipe indicated the pipes over 15 years old had lost 50-100% of their lime active cross sectional area.

South Korea's low birth rate, aging society, and female migration to urban areas due to industrialization have caused an accelerated inflow of Asian female immigrants into Korea to marry Korean men, especially in rural areas. This study was performed to determine how family function of multicultural families changes over time and what factors affect the changes in family function of multicultural families. The study subjects were 62 Asian immigrant women married to South Korean men living in South Korea. In a 1st wave study in August 2008, the socioeconomic factors and Family Adaptability and Cohesion Scale III (FACES III) scores were measured. A 3-year follow-up study was then conducted in August 2011, and the results were compared with the 1st wave study results. The mean family adaptability score was 24.6 in the 1st wave study and 26.1 at the 3-year follow-up. The average family cohesion score was 31.0 in the 1st wave study and 36.7 at the 3-year follow-up. There was a statistically significant increase in family cohesion after 3 years (P adaptability did not change over time; however, conversely, family cohesion increased. The age difference between husband and wife and the subjective SES had a positive association with the changes in family cohesion. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

Since the 2006 Pandemic Influenza Preparedness and Response Plan according to the World Health Organization’s recommendation, the Republic of Korea has prepared and periodically evaluated the plan to respond to various public health crises including pandemic influenza. Korea has stockpiled 13,000,000 doses of antiviral drugs covering 26% of the Korean population and runs 519 isolated beds in 16 medical institutions. The division of public health crisis response in Korea Centers for Disease Control and Prevention are in charge of responding to public health crises caused by emerging infectious diseases including severe acute respiratory syndrome, avian influenza human infection, and pandemic influenza. Its job description includes preparing for emerging infectious diseases, securing medical resources during a crisis, activating the emergency response during the crisis, and fortification of capabilities of public health personnel. It could evolve into a comprehensive national agency to deal with public health crisis based on the experience of previous national emerging infectious diseases. PMID:24298444

Psychosocial rehabilitation programs received mental health professional support in addition to traditional medication therapy. Many psychosocial programs were developed since the 1990s, including cognitive remediation therapy. In this review, we focus on cognitive remediation therapy in Korea since the 1990s. We review several cognitive rehabilitation programs developed in Korea and their outcome studies and suggest future research directions and prospects. We reviewed cognitive rehabilitation programs including social cognitive training as well as more recent forms of computerized cognitive rehabilitation. Although there are differences in cognitive domains by training targets, almost all neurocognitive remediation trainings in Korea have beneficial effects on early visual processing, various attention types, and executive function. Future studies need to investigate the mechanisms and various mediators underlying the relationships between cognitive functions and functional outcomes. With more comprehensive cognitive and social cognitive programs, we can enhance both cognition and functional outcomes of the patients with schizophrenia. Copyright © 2016 Elsevier B.V.

The Hebei Spirit oil spill (HSOS) on December 7, 2007 was the worst oil spill recorded in Korea, with the release of approximately 10,900 tons of crude oil and 375 km of coastline polluted along the west coast of Korea. Cleanup operation was conducted by official and contract responders as well as volunteers for massive oil containment and removal of heavy accumulations of stranded oil. Together with the oil cleanup, a long-term environmental impact assessment (EIA) of the HSOS was initiated based on the Marine Environmental Management Act, which covers oil contamination in a multimedia environment, toxic effects on organisms, and ecosystem injury. This review summarizes the long-term monitoring results of HSOS EIA focused on (1) pollution status of seawater, sediment, and bivalves, (2) ecotoxicological effects, and (3) ecosystem recovery. Overall, concentrations of petroleum hydrocarbons in the environment indicated that their concentrations were well down to at or near background or pre-spill contamination levels at most sites after 1 year. The potential toxic effects of residual oils in sediments have decreased to background levels in most coastal areas of Taean. The entire ecosystem in the most affected area of the Taean coasts appear to be considerably, but not fully, recovered at present, namely after 8 years of the HSOS. The presence of lingering oil and elevated contamination levels at several sites still require continuous long-term monitoring.

The purpose of this research is to analyse the conflicts that arise among major stakeholders during the process of disaster management and to suggest policy recommendations for improving disaster management systems. It describes several important conflict cases that have occurred among major stakeholders, such as governments, private-sector entities, and non-governmental organisations, during natural disaster management. In addition, it probes the similarities and the differences between such conflicts in the Republic of Korea and the United States. The differences between them may originate from a range of factors, such as the disaster itself, cultural features, management practices, and government organisation. However, the conflicts also are very similar in some ways, as the motivations and the behaviour of stakeholders during a disaster are alike in both countries. Based on this comparison, the study presents some common and important implications for successful disaster management practices in Korea and the US, as well as in many other nations around the world. © 2016 The Author(s).

The Republic of Korea has undergone rapid development and urban development without sufficient consideration of the environment. This type of growth is accompanied by a reduction in forest area and wildlife habitat. It is a phenomenon that affects the habitat of large mammals more than small. Especially in Korea, the damage caused by wild boar(Sus scrofa) is harsher than other large mammalian species like water deer(Hydropotes inermis), which also means that the number of these reported cases of this species is higher than ones of other mammals. Wild boar has three to eight cubs per year and it is possible to breed every year, which makes it more populous comparing with the fragmented habitats. It could be regarded as one of the top predators in Korea, which it is inevitable for humans to intervene this creature in population control. In addition, some individuals have been forced to be retreated from other habitats in major habitats, or to invade human activity areas for food activity, thereby destroying crops. Ultimately, this mammal species has been treated as farm pest animals through committing road kills and urban emergences. In this study, we has estimated possible farm pest animal present points from the damage district using 2,505 hazardous wildlife damage areas with four types of geological informations, four kinds of forest information, land cover, and distribution of farmland occurred in Gyeongnam province in Korea. In the estimating model, utilizing MAXENT, information of background point was set to 10,000, 70% of the damaged sites were used to construct the model, 30% was used for verification, and 10 times of crossvalidate were proceeded - verified by AUC of ROC. As a result of analyses, AUC was 0.847, and the percent contribution of the forest information was the distance toward inner-forest areas, 36.1%, the land cover, 16.5%, the distance from the field, 14.9%. Furthermore, the permutation importance was 24.9% of the cover, 12.3% of the height

Nuclear Option in Korea

With sixteen(16) operating nuclear units in Korea, the share of nuclear power generation reached 41% of the total electric power generation as of December 2000. A prediction is that it would further increase to 44.5% by year 2015 according to the national long term power development plan. Four units are currently under construction with 6 more units in order. With little domestic energy resource and increasing energy demand to support national economic growth, Korea has chosen nuclear power as one of the major energy sources to ensure stable power supply and to promote energy self-sufficiency. It has been recognized that nuclear power in Korea is not a selective option but rather a necessity. The Korean nuclear power development started with construction of a 600 MWe size reactor that was designed and constructed by foreign vendors. As the national grid capacity became larger, the size of nuclear units increased to 1000 MWe class. In the mean time, the need for nuclear technology self-reliance grew not only in operation and maintenance but also in construction, manufacturing and design. For this, a nuclear technology self-reliance program has been embarked with the support of the Government and utility, and the 1000 MWe class KSNP(Korean Standard Nuclear Power Plant) has been developed. The KSNPs are currently being designed, manufactured, constructed and operated by relevant Korean entities themselves. To fit into a larger capacity national grid and also to improve nuclear economic competitiveness, the 1400 MWe class KNGR(Korean Next Generation Reactor) design has been developed uprating the 1000 MWe KSNP design. Its construction project is currently under contract negotiation, and is planned to be finished by 2010. In the mean time, to be ready for future electric power market deregulation, the 600 MWe class small KSNP design is being developed downsizing the KSNP. A modular small size reactor, SMART(System Integrated Modular Advanced Reactor) is also being

North Korea's nuclear weapon development is a serious threat to South Korea's national security and can become a trigger to change the status quo in the Korean peninsula. Having prevailed security dynamics in Northeast Asia last 20 years, the North Korea's nuclear problem faced a key turning point when Pyongyang tested its first nuclear weapon on October 9, 2006. Despite this test, however, diplomatic efforts to resolve the nuclear issue were never given up, resulting in a so-called, initial agreement signed at the Six-Party Talks in February 2007. With the Six-Party Talks being held more than four years, the six countries have had sufficient time to discuss principal and political matters regarding the dismantlement of North Korea's nuclear weapons. Under the circumstances, this report is going to study practical and detail issues related with dismantling the North's nuclear weapons. Specifically, in light of historical experiences, the report will investigate possible problems to be faced in the course of dismantlement and propose policy measures to overcome these problems

Science, state, and spirituality: Stories of four creationists in South Korea.

Science.gov (United States)

Park, Hyung Wook; Cho, Kyuhoon

2018-03-01

This paper presents an analysis of the birth and growth of scientific creationism in South Korea by focusing on the lives of four major contributors. After creationism arrived in Korea in 1980 through the global campaign of leading American creationists, including Henry Morris and Duane Gish, it steadily grew in the country, reflecting its historical and social conditions, and especially its developmental state with its structured mode of managing science and appropriating religion. We argue that while South Korea's creationism started with the state-centered conservative Christianity under the government that also vigilantly managed scientists, it subsequently constituted some technical experts' efforts to move away from the state and its religion and science through their negotiation of a new identity as Christian intellectuals ( chisigin). Our historical study will thus explain why South Korea became what Ronald Numbers has called "the creationist capital of the world."

Full Text Available To identify genome sequences of Apple scar skin viroid (ASSVd isolates in Korea, the field survey was performed from ‘Hongro’ apple orchards located in eight sites in South Korea (Bongwha, Cheongsong, Dangjin, Gimchoen, Muju, Mungyeong, Suwon, and Yeongwol. ASSVd was detected by RT-PCR and PCR fragments were cloned into cloning vector. Full-length viral genomes of eight ASSVd isolates were sequenced and compared with 21 isolates reported previously from Korea, India, China, Japan and Greece. Eight isolates in this study showed 92.2-99.7% nucleotide sequence identities with those reported previously. Phylogenetic analysis showed that seven isolates reported in this study belong to the same group distinct from other groups.

This study evaluated blood lead concentrations in the Korean general population and the correlation between various exposure sources using data from the 2008 Korea National Survey for Environmental Pollutants in the Human Body (National Institute of Environmental Research, Korea). The general and occupational characteristics were gathered from 5136 participants who were 20 years of age and older using a structured questionnaire. Blood lead concentrations were analyzed using an atomic absorption spectrophotometer. Statistical analysis was performed using multiple linear regressions of the log lead concentrations to the independent variables such as age, gender, smoke, herbal medication and drug consumption, drinking water, and living area. Geometric mean (GM) blood lead concentrations in Korean adults were 19.7 μg/l. The blood lead concentrations increased with age; the highest concentrations were found in the 50-69-year age group (pdrug consumption were higher than those who did not (plead concentration (plead concentration (plead concentration, but not significantly. For drinking water, the underground water (spring or well water) drinking group had higher concentrations than other types of water drinking groups, but not significantly (p=0.063). The blood lead concentrations by occupation were significant (plead concentrations tended to decrease with increasing delivery times, but not significantly. The blood lead concentration (GM) of the general adult population in Korea has decreased over time from 45.8 μg/l (1999) to 19.7 μg/l (2008). Although it is still higher than in other countries such as the United States and Canada, it is rapidly decreasing. Gender, age, smoking and alcohol drinking status, herbal medication and drug consumption, education level, living area and occupation were significantly related to the blood lead concentrations in Korea.

Understanding the contribution of suicide to life expectancy in South Korea

Directory of Open Access Journals (Sweden)

Aggie Noah

2016-09-01

Full Text Available Background: South Korea has the highest rate and highest rate of increase in suicide among developed countries. The suicide epidemic in Korea is an anomaly, and suicide rates are high for both men and women, with no signs of decreasing. Yet we do not know the extent to which suicide has reduced life expectancy in Korea. Objective: We investigated whether and to what extent the rapid increase in suicide has contributed to changes in Korean life expectancy, a key indicator of population health. Methods: We used a recently developed decomposition method that separates the contribution of suicide's effect on change in life expectancy into two parts: that due to change in the overall suicide incidence rate and that due to change in the mean age of suicide victims. Results: From 1995 to 2010, life expectancy increased by 6.5 years in Korea, with change in most causes of death contributing to its growth. We nonetheless find, as expected, that the rise in suicides reduced the increase in life expectancy from 1995 to 2010, so life expectancy in Korea is about 0.21 years lower than it would have been without the increase in suicides. Moreover, had the age of suicide victims remained stable, we project that Korea's life expectancy would be fully 0.70 years lower than it is. Conclusions: Although the growth in suicide was the largest single factor slowing the rise in Korean life expectancy, the effect would have been even larger had the age of suicide victims not increased.

For the decentralization of the North Korea, the decommissioning of the weapon related facilities should be dismantled and the site be decontaminated and restored to the green field. To achieve this final target, Korea should lead the dismantlement projects of the North Korea facilities, sharing work scopes with the member countries of 6 member talks. Many essential technologies for decommissioning of nuclear facilities was acquired and it was concluded that Korean industries could carry out the decommissioning of the North Korea facilities by the some modification or development of the current existing technologies and sharing some tasks for decommissioning of the NK facilities with member countries of 6 member talk

Nuclear and energy policy in Korea. Unchanging illusion of nuclear energy and citizens' challenge

International Nuclear Information System (INIS)

Leem, S.J.

2006-01-01

Korea is the tenth largest energy consumer in the world; the country ranks sixth in oil consumption, seventh in electricity consumption, and ninth in total CO2 emission. Korea now has 20 reactors in operation, nuclear power producing about 40% of its electricity. Its generating capacity from nuclear power plants is the sixth largest in the world; Korea currently exports nuclear technology. The rapid growth of this industry is attributed to extensive subsidy and protection from the Korean government; supported by government-initiated programs a powerful interest group, which consists of nuclear industries, technocrats, and governmental organizations concerned with nuclear policy, now exerts a major influence upon Korea's energy policy for nuclear expansion. Korea's nuclear power policymakers have, however, met opposition since End of the 1980s. The government's attempt to build a nuclear waste repository has provoked strong resistance from environmental movements and local citizens. Even if the government recently succeeded in designating Kyoungju as the nuclear waste site, the nuclear waste issue has awakened public interest in nuclear problems and strengthening public denunciation of Korea's expansive nuclear power policy. In addition, the activation of the Kyoto Protocol in February 2005 has impelled the government to redirect its energy policy towards a sustainable direction. This article focuses on the status and perspectives of Korea's nuclear power policy, enabling a discussion of the degree to which Korea's nuclear and energy policy has changed yet in many ways remains unchanged.

Regionalization of Drought across South Korea Using Multivariate Methods

Directory of Open Access Journals (Sweden)

Muhammad Azam

2017-12-01

Full Text Available Topographic and hydro-climatic features of South Korea are highly heterogeneous and able to influence the drought phenomena in the region. The complex topographical and hydro-climatic features of South Korea need a statistically accurate method to find homogeneous regions. Regionalization of drought in a bivariate framework has scarcely been applied in South Korea before. Hierarchical Classification on Principal Components (HCPC algorithm together with Principal Component Analysis (PCA method and cluster validation indices were investigated and used for the regionalization of drought across the South Korean region. Statistical homogeneity and discordancy of the region was tested on univariate and bivariate frameworks. HCPC indicate that South Korea should be divided into four regions which are closer to being homogeneous. Univariate and bivariate homogeneity and discordancy tests showed the significant difference in their results due to the inability of univariate homogeneity and discordancy measures to consider the joint behavior of duration and severity. Regionalization of drought for SPI time scale of 1, 3, 6, 12, and 24 months showed significant variation in discordancy and homogeneity of the region with the change in SPI time scale. The results of this study can be used as basic data required to establish a drought mitigation plan on regional scales.

The Impact of the Canada-Korea Free Trade Agreement as Negotiated

Directory of Open Access Journals (Sweden)

Dan Ciuriak

2014-12-01

Full Text Available This paper analyzes the impact of the Canada-Korea Free Trade Agreement on the basis of the published text and agreed schedule of commitments. We find that the Agreement reinforces existing patterns of comparative advantage between Canada (agriculture and resource-based sectors and Korea (autos and other industries. The sensitive sectors that held up the deal for years - autos into Canada and beef into Korea - witness major trade gains, but are not unduly disrupted. In both economies, the major output gains otherwise come in non-traded services sectors, driven by income effects. We find that trade diversion effects are quite significant; this lends support for the domino theory of major free trade agreements - since the Korea-EU agreement broke the ice, the pressure has intensified on third parties to re-level playing fields by striking their own deals. The study breaks new ground in modelling services trade by developing policy impacts based on the extent to which the text of the Agreement modifies Korea's and Canada's scores on the OECD's Services Trade Restrictiveness Index and by providing estimates of Mode 3 Services trade impacts. The analysis of the Agreement as negotiated, the present study, in our view, is a step forward in understanding the impact of modern free trade agreements.

It is noteworthy that North Korean government itself has demanded other parties' cooperation in the field of power sector as the top priority to deal with North Korean own economic issues. In this light, the researcher consider that how to build power capacity in North Korean area after reunification needs to be studied with priority. A scenario-based approach is being adopted, and three scenarios are proposed: Scenario increasing capacity at 2.4% annual rate, Imitating South Korean electricity expansion history, and reaching 80% of South Korean Annual Peak Load in 35 years. In order to carry out the research, WASP-IV (Wien Automation System Planning-IV) code developed by IAEA is, with reasonable assumptions, being executed. Annual Peak Load prediction for each scenario, load duration curve, and existing power generating facilities in North Korea are presented herein. This research is being conducted as a preparatory work for the further study. IAEA's WASP-IV is adopted for a scenario-based electricity expansion plan for North Korea after hypothetical reunification between Koreas. Input data including Annual Peak Load, load duration curve, and existing facilities are built and presented. Additional future research includes inputting candidate plants data, cost data such as construction period, operation and maintenance costs, and fuel costs, as well as decommissioning of aged power plants in North Korea to complete WASP-IV execution. Assuming reunification, electricity expansion plan would need to integrate North and South Koreas demands and facilities. However, this research narrows down its scope to North Korean demand and facilities only. Such integrated simulation could be the topic for the later research. This work was supported by the 2014 Research Fund of the KINGS.

Does Technology Transfer Help Small and Medium Companies? Empirical Evidence from Korea

Directory of Open Access Journals (Sweden)

Dae-Hwan Kim

2016-11-01

Full Text Available We challenge the view that technology transfer from big companies to small and medium (SM size companies helps SM companies to prosper. With a large dataset of SM companies in Korea, we utilize the stochastic production frontier (SPF model to examine the productivity of inputs and the generalized linear model (GLM to compare business performance between two groups of SM companies: SM companies that receive technology transfer and those that do not receive technology transfer from big companies. The empirical results demonstrate that the transfer of technology from big companies to SM companies help SM companies to enjoy productivity of capital. Nonetheless, SM companies receiving technology transfer were found to underperform in terms of labor productivity and profit margin compared to their counterparts. We further investigate the reasons why SM companies receiving technology transfer from big companies underperform relative to their counterparts, and our findings shows that the former do not export much of their product and face more difficulties such as lower price for their products imposed by big companies than the latter. By identifying the negative rather than the conventionally assumed positive effect of technology transfer, this paper contributes to the literature on the relationship between technology transfer and SM companies’ prosperity in the case of Korea. Our findings have important implications for how SM companies should strategize and rethink about the clauses embedded in the transfer of technology that they receive from big companies because technology transfer plays as a barrier to their prosperity.
