    The main focus of this study is to investigate how body image and attachment style among university students are related. We approach these different student types on a cross sectional dataset including 898 university students from Denmark, Germany, Portugal, Croatia and Czechoslovakia. Based...... on the combination of the Body Esteem Scale (BES) and the Attachment Style Scale (WASQ) we create four types: "double jeopardy students", "well-balanced students", "nurturing solitude students" and "social mirroring students". The "double jeopardy students" are students with low social attachment and a high dislike...... of their body. Based on this combination of body image and social attachment we investigate how these four student types are related to three different dimensions: parental characteristics, northern versus southern countries and different field of study....

    Full Text Available The purpose of this study was to measure selected anthropometrical characteris-tics, motor abilities and cardiorespiratory functions of medical students. Eighty-seven students were involved in this investigation. The students were categorized into five groups: (1 recreational, doing sport activities irregularly, (2 basketball and (3 handball players, having training at least two times per week, as well as men (4 and women (5 students entering medical school. In all groups the mean body mass index and waist-to-hip ratio were at the upper level of the normal range, while body fat percentage was similar to standards for sedentary subjects. Better motor per-formances were obtained from the basketball and handball players than from the other groups. Static strength for the sample was somewhat above the normal sedentary level. The resting blood pressure and heart rate for most subjects were in the normal. Cardiovascular risk factors were found in six students. Their systolic blood pressure was above 140 mm Hg. There were no sub-jects identified with low blood pressure. The heart rate was elevated for three students from the recreational group, and in the women. Bradycardia did not occur. The vital capacity and the ability to hold one’s breath was at the upper level of the normal range. The present results emphasis the need to improve the students` prevention oriented life style through participation in exercising.

    Full Text Available Background. The recommended number of daily meals is three to five. The aim of this study was to establish the number of meals, daily consumed by secondary school students from Ljubljana, and the relationship with nutritional and other habits, including bad habits, demographic and socio-economic characteristics of the secondary school students and their body mass index.Methods. In 1999, an cross-section epidemiological study was performed on a proportional sample of 296 pupils attending the third class of Ljubljana secondary schools. The applied dietary data collection methods were the survey and the 24-hour dietary recall. The body mass index was calculated on the basis of the measured body height and body mass values. The Chi-square test, t-test, variance analysis and the multivariant linear regression method were used for the analysis.Results. The students consume 3.16 meals per day on average (boys 3.44, girls 2.87. The students who reported a smaller number of meals per day consume statistically significantly less fruit, vegetables, milk, milk products and fish. They take hot meals less frequently, consume less often all daily meals, their daily meals are of a poorer quality in respect to their composition, they eat less often their meals in a sitting position, they feel a greater difference in diet between working week days and weekends, their regular nourishment is more influenced by school obligations, they have poorer knowledge of healthy dietary practices, smoke more often, are less satisfied with their weight, are less physically active and girls sleep less at nights. The inverse proportional relationship between the number of daily meals and the body mass index was not statistically significant. The multivariant linear regression model explained the low variance percentage (R2 = 0.28.Conclusions. The average number of daily meals consumed by schoolboys is at the lower border of recommendations, while the average number of daily meals

    Are pre-medical students different than the other students in a General physics class? They often appear to be different, based on how often they seek help from the instructor or how nervous they are about 2 points on a lab report. But are these students different in a measurable characteristic? The purpose of this study is to better understand the characteristics of the students in the introductory physics classes. This is the first step toward improving the instruction. By better understanding the students the classroom, the organization and pedagogy can be adjusted to optimize student learning. The characteristics to be investigated during this study are: · student epistemological structure, · student attitudes, · science course preparation prior to this course, · study techniques used, · physics concepts gained during the class · performance in the class. The data will be analyzed to investigate differences between groups. The groups investigated will be major, gender, and traditional/nontraditional students.

    Full Text Available Abstract OBJECTIVE To investigate the body posture of nursing students before and after clinical practice. METHOD The study was developed in two stages. Initially the body posture of students of the 2nd, 4th, 6th, and 8th periods were assessed through photogrammetry. All images were analyzed in a random and masked manner with CorporisPro® 3.1.3 software. Three evaluations were performed for each angle and then the mean value was calculated. Two years later, when the 4th period students had developed their clinical internships, their body posture was again evaluated. RESULTS The total sample consisted of 112 students. Comparison of their posture with the normality pattern showed that all the angles presented significant differences (p< 0.00, except for the angle of the Thales triangle. Reassessment of these students evidenced significant differences in the angles of the acromioclavicular joint (p=0.03, knee flexion (p< 0.00 and in the tibiotarsal angle (p< 0.00. CONCLUSION All the students presented alterations when compared to the normality values. The segments that presented significant differences between before and after practice were the acromioclavicular angle, knee flexion, and tibiotarsal angle; the latter two were in the rolling position.

    The present study aimed to examine body image attitude in Chinese college students and related psychological consequences. A silhouette-matching test was administered to 425 college students in mainland China. Self-esteem, negative emotions, subjective well-being, and eating-disorder-related weight-controlling behaviors were also measured. Only 12.9% of the participants were satisfied with their figure and the extent of body image dissatisfaction was comparable for both sexes. The majority of the female participants indicated a preference to be more slender. Their ideal figure was underweight and was far smaller than the most attractive female figure chosen by male participants. For male participants, the proportion wanting a fuller figure was comparable to that wanting a slimmer figure. Among female participants, body image dissatisfaction negatively correlated with self-esteem and subjective well-being, and positively correlated with negative emotions. Drive for thinness correlated with eating-disorder-related weight-controlling behaviors not only for females, but also for males. Body image dissatisfaction, as a diagnostic feature for major subtypes of eating disorders, may signal serious concern among Chinese college students. © 2018 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

    This paper uses qualitative methodologies to understand young people's use of technology in the management of Type 1 diabetes. The paper begins by outlining the nature of Type 1 diabetes. We provide an account of recent debates on the consumption of health-care technologies. We consider the advantages of qualitative approaches for studying young people with diabetes. Our specific focus is on university students with diabetes who are commonly represented as having a lifestyle that is ill-suited to good management of the disease. We consider the pros and cons that these young people associate with their technologies, and the role that place plays in these young people's accounts. We argue that diabetes' management technologies provide these young people with the ability to discipline their bodies and position their identities as 'normal' students in student spaces, as well as to manage risks to their health and identities. However, we highlight that the use of these technologies, especially in public spaces such as student night-clubs and bars, poses risks for students with diabetes, for example, by highlighting their 'difference' from other students.

    The aim of this study was to determine the personality characteristics of obese and morbidly obese individuals with no psychiatric disorder and the correlation between these characteristics and body image and self-esteem. Sixty-nine obese individuals and 69 healthy controls, matched in age, sex and marital status, were included in the study. Psychiatric disorders were excluded for all participants using SCID-I and II. Obese and healthy volunteers were compared in terms of body image, self-esteem and personality characteristics. TCI harm avoidance scores were higher in obese individuals compared to healthy controls. Harm avoidance scores were also higher in individuals with morbid obesity compared to non-morbid individuals, while self-directedness and persistence scores were lower. Body image dissatisfaction was higher in obese individuals. There was a negative correlation in obese individuals between body image and self-esteem scale scores and harm avoidance scores, and a positive correlation with self-directedness scores. An elevated harm avoidance temperament characteristic may be correlated with obesity. Furthermore, high harm avoidance, low self-directedness and low persistence may be significant personality characteristics in a process leading to morbid obesity. In addition, harm avoidance temperament and self-directedness personality characteristics may be correlated with body image dissatisfaction and self-esteem in obese individuals.

    At the time of settlement to the reef environment, coral reef fishes differ in a number of characteristics that may influence their survival during a predatory encounter. This study investigated the selective nature of predation by both a multi-species predator pool, and a single common predator (Pseudochromis fuscus), on the reef fish, Pomacentrus amboinensis. The study focused on the early post-settlement period of P. amboinensis, when mortality, and hence selection, is known to be highest. Correlations between nine different measures of body condition/performance were examined at the time of settlement, in order to elucidate the relationships between different traits. Single-predator (P. fuscus) choice trials were conducted in 57.4-l aquaria with respect to three different prey characteristics [standard length (SL), body weight and burst swimming speed], whilst multi-species trials were conducted on open patch reefs, manipulating prey body weight only. Relationships between the nine measures of condition/performance were generally poor, with the strongest correlations occurring between the morphological measures and within the performance measures. During aquaria trials, P. fuscus was found to be selective with respect to prey SL only, with larger individuals being selected significantly more often. Multi-species predator communities, however, were selective with respect to prey body weight, with heavier individuals being selected significantly more often than their lighter counterparts. Our results suggest that under controlled conditions, body length may be the most important prey characteristic influencing prey survival during predatory encounters with P. fuscus. In such cases, larger prey size may actually be a distinct disadvantage to survival. However, these relationships appear to be more complex under natural conditions, where the expression of prey characteristics, the selectivity fields of a number of different predators, their relative abundance, and

    Medical students must consider many overt variables when entering the National Resident Matching Program. However, changes with the single graduate medical education accreditation system have caused a gap in knowledge about more subtle considerations, including what, if any, influence the presence of osteopathic physician (ie, DO) and international medical graduate (IMG) house officers has on allopathic students' residency program preferences. Program directors and selection committee members may assume students' implicit bias without substantiating evidence. To reexamine which program characteristics affect US-trained allopathic medical students' residency selection, and to determine whether the presence of DO and IMG house officers affects the program choices of allopathic medical students. Fourth-year medical students from 4 allopathic medical schools completed an online survey. The Pearson χ(2) statistic was used to compare demographic and program-specific traits that influence ranking decisions and to determine whether school type (private vs public), valuing a residency program's prestige, or interest in a competitive specialty dictated results. Qualitative data were analyzed using the Pandit variation of the Glaser and Strauss constant comparison. Surveys were completed by 323 of 577 students (56%). Students from private vs public institutions were more likely to value a program's prestige (160 [93%] vs 99 [72%]; P<.001) and research opportunities (114 [66%] vs 57 [42%]; P<.001), and they were less likely to consider their prospects of being accepted (98 [57%] vs 111 [81%]; P<.001). A total of 33 (10%) and 52 (16%) students reported that the presence of DO or IMG trainees, respectively, would influence their final residency selection, and these percentages were largely unchanged among students interested in programs' prestige or in entering a competitive specialty. Open-ended comments were generally optimistic about diversification of the physician

    Often teachers provided examples and exercised to students with regard to comparative problems consisting of one quantity. In this study, the researchers gave the problem of comparison with the two quantities mixed. It was necessary to have a good understanding to solve this problem. This study aimed to determine whether students understand the comparison in depth and be able to solve the problem of non-routine comparison. This study used qualitative explorative methods, with researchers conducting in-depth interviews on subjects to explore the thinking process when solving comparative problems. The subject of this study was three students selected by purposive sampling of 120 students. From this research, researchers found there were three subjects with different characteristics, namely: subject 1, he did the first and second questions with methods of elimination and substitution (non-comparison); subject 2, he did the first question with the concept of comparison although the answer was wrong, and did the second question with the method of elimination and substitution (non-comparison); and subject 3, he did both questions with the concept of comparison. In the first question, he did wrong because he was unable to understand the problem, while on the second he did correctly. From the characteristics of the answers, the researchers divided into 3 groups based on thinking process, namely: blind-proportion, partial-proportion, and proportion thinking.

    For many years, body dissatisfaction and mental health were thought of as Western phenomena and were studied mostly in Caucasian women. Recent studies, however, suggest that these issues are also present in men and in other ethnic groups. This study examined the association between body dissatisfaction and mental health outcomes, with personality traits and neuroticism playing possible predictive roles, using a Korean sample. A total of 545 college students, from five private universities in South Korea, completed assessment measures for depression, self-esteem, neuroticism, and body esteem scales. After controlling for covariates including body mass index and exercise time, body dissatisfaction was seen to play a mediating role between neuroticism and mental health outcomes. Differences between the sexes were also found in this relationship. For men, body dissatisfaction acted as a mediator between neuroticism and depression. For women, body dissatisfaction acted as a mediator between neuroticism and both depression and self-esteem. © The Author(s) 2016.

    Body dysmorphic disorder (BDD) is a distressing psychiatric disorder. So far there have not been any studies on BDD in Saudi Arabia. The aim of this study was to determine the prevalence of body dysmorphic disorder in female medical students and to investigate whether there is an association between BDD and body features of concern, social anxiety and symptoms of BDD. A cross sectional study was carried out on female medical students of the college of medicine, King Saud University, Riyadh, Saudi Arabia during January to April, 2015. Data were collected using the body image disturbance questionnaire, Body dysmorphic disorder symptomatology and social interaction anxiety scale. Descriptive statistics, bivariate and multivariate analysis were used to analyze the results. Out of 365 students who filled out the questionnaire, 4.4% (95% confidence intervals (CI): 2.54% to 7.04%) were positive for BDD with skin (75%) and fat (68.8%) as the most frequent body features of concern. Ten features (skin, fat, chest, hips, buttocks, arms, legs, lips, fingers, and shoulders) out of twenty-six were significantly associated with BDD. Arms and chest were independently associated with BDD. The odds of presence of body concern related to "arms" was 4.3 (95% C.I: 1.5, 12.1) times more in BDD subjects than non-BDD subjects, while concern about "chest" was 3.8 (1.3, 10.9) times more when compared to non-BDD subjects. No statistically significant association was observed between BDD and social anxiety (P = 0.13). This was the first study conducted in Kingdom of Saudi Arabia (KSA) on female medical students, which quantified the prevalence of BDD and identified the body features associated with it. Body dysmorphic disorder is prevalent in female medical students but it is relatively rare and an unnoticed disorder.

    The aim of this study was to assess food behavior, self-image perception and anthropometric indices of college students. This was a cross-sectional study with 54 students in a public university. The lifestyle and self-image perception was collected using a standardized questionnaire tested. Food behavior was evaluated through the Eating Attitudes Test. Body composition was assessed for Body Mass Index (BMI, circumferences, skinfold analysis and bioelectrical impedance (BIA. The statistics tests used were Chi-square and Pearson correlation (p< 0.05. The students had 19 to 27 years old, 96.3% were non-smokers, 46.3% drank alcoholic beverages and 37.0% practiced regular physical activity. Most of the students (75.5% were considered normal weight (BMI but the body fat percentage was found to be above average. Regarding self- image perception, 40.7% felt overweight. Observing food behavior results, 12.0% were at risk of developing eating disorders. Positive correlations were verifi ed between BMI with skinfold and skinfold with bioelectrical impedance. It was concluded that a considerable number of the college students assessed had a distorted self-image perception. Many of them had normal weight but with high body fat percentage. This study is relevant to investigate the risk of eating disorders and body image perception as part of the nutritional assessment.

    Full Text Available The aim of this study was to analyze the association between substance use and body mass index (BMI among adolescents in Southern Taiwan. A total of 10,259 adolescent students aged 11–19 years were selected by stratified random sampling for proportional representation of districts, schools and grades in Southern Taiwan, and completed the questionnaires. The body weight, body height, experience of substance use and sociodemographic characteristics including sex, age, residential background and paternal/maternal educational levels were collected. The association between substance use and BMI, and the moderating effects of sociodemographic characteristics were examined. After adjusting for sociodemographic characteristics, BMI was higher for adolescents who smoke cigarettes or drink alcohol than for those who do not regularly smoke or drink. Chewing betel nuts and using illicit drugs were not significantly associated with BMI. Paternal education level had a moderating effect on the association between smoking and BMI. Smoking, alcohol drinking, and low paternal education level were associated with higher BMI among adolescents. Thus, healthcare professionals should pay more attention to the weight-related problems among these adolescents.

    Full Text Available For K-12 students, obesity has been linked to student educational achievements. The study objective was to determine whether academic performance in university students is correlated with BMI. Students from two consecutive academic years (Jan–May 2013 and Jan–May 2014 were given an optional class survey in May, as extra credit. Of the 452 students that completed the survey, 204 females and 75 males (N = 279; 73% female and 27% male consented to participate in the study. The number of correct answers to problem-solving questions (PSQs and the overall final grade for the class were compared to the calculated BMI using linear regression with a Pearson's R correlation and unpaired t-tests. BMI was significantly negatively correlated with student's final grades (P = 0.001 Pearson's r = −0.190 and PSQs were positively correlated with final grades (P < 0.001; Pearson's r = 0.357. Our findings show a correlation between healthy body weight and improved academic performance. Further, the data suggest that future research in the area of body weight, diet, and exercise and any correlations of these with academic performance in college students are warranted.

    One of the strategies for the prevention of the obesity is the identification of critical periods of gain weight. Some studies confirm gain weight during the university period. The purpose of the present study was to determine the changes in the body weight of the university students in Navarre. Prospective cohort study. Public University of Navarre and the University of Navarre, in Pamplona. Study examined weight change among 452 students attending at university in Pamplona, during first and third course. Four hundred and fifty two students completed the questionnaire. Weight and height were measures and body mass index was calculated. The mean body weight increased 0,600 kg, 1,8 kg for males and no change in body weight was observed in female. 44,7 % of students gained weight (60,8 % of men and 36,8 % of women), and the gain weight was of 3,4 kg. University years are a critical factor for the gain weight, particularly males. Consideration of this, is necessary the development of effective weight gain prevention strategies during the university. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    Full Text Available The article deals with student term-time employment in Croatia, causes of its growing prevalence, its patterns and legal regulation, and finally its effects on the higher education system and labour market. Overview of the theories on combining work and study singled out few relevant factors determining motivations of students for engaging in term-time employment and employment's different academic and professional outcomes, mainly related to the massification of higher education phenomenon (higher number of students and their greater diversity, youth unemployment, and questionable college degree relevance. Although conducted on non-systematic data, gathered from previous research of student population in Croatia and EUROSTUDENT international research on the quality of student life, analysis carried out in this article showed the occurrence of higher education massification and its influence on student employment, especially in the fields of social sciences and humanities. Croatian students' motivations for term-time employment are mainly a wish to improve their living standard and a need for work experience, while their average workload is of low to medium intensity, usually on jobs not at all related to their future profession. Apart from presenting the practice of student work use, this article also gives an overview of its legal regulation in Croatia, and examples of its misuse, i.e., negative implications it may have on student and regular workers.

  8. Design and characteristics of a 4 MV total body irradiator

    Lutz, W.R.; Chin, L.M.

    1988-01-01

    A facility for total body X-ray irradiation (TBI) has been built using two 4 MV linear accelerators, one mounted under the ceiling, the other in a floor-pit. The distance between the two sources is 410 cm to produce a field size of 200 cm x 75 cm in the midplane. This field covers the patient, lying supine on a stretcher halfway between the sources. Components from commercially available accelerators were used. Special beam hardening and flattening filters were built to achieve acceptable dose profiles in the large field. The primary collimator was modified to produce a 235 cm x 92 cm field at 205 cm from the source, while movable focused collimators were designed to define fields up to 220 cm x 80 cm. Because of the wide beams, large rectangular parallel-plate ionization chambers were built to serve as beam monitors. The dose rate at 205 cm distance from the sources can be set between 5 and 80 cGy/min, each machine contributing half. The dosimetric characteristics are practically the same for both units. The per cent depth dose for the TBI beams is 76% at a source-surface distance of 195 cm. The half value layer decreases by 12% from the centre to near the edge of the beam. Owing to the large field size, the surface dose for the TBI beams is about 80% of the dose at 1 cm depth. The dose delivery has been verified to be within 2% of the calculated value at the reference point in a homogeneous water humanoid phantom. Measurements indicate that lung doses can be predicted by the ratio-of-TMR (tissue-to-maximum ratio) method with acceptable accuracy. Lead sheets are used as attenuators to prevent excessive lung doses. (author). 7 refs, 7 figs

  18. Body talk: students' identity construction while discussing a socioscientific issue

    Ideland, Malin; Malmberg, Claes

    2012-06-01

    Vision II school science is often stated to be a democratic and inclusive form of science education. But what characterizes the subject who fits into the Vision II school science? Who is the desirable student and who is constructed as ill-fitting? This article explores discourses that structure the Vision II science classroom, and how different students construct their identities inside these discourses. In the article we consider school science as an order of discourses which restricts and enables what is possible to think and say and what subject-positions those are available and non-available. The results show that students' talk about a SSI about body and health is constituted by several discourses. We have analyzed how school science discourse, body discourse and general school discourse are structuring the discussions. But these discourses are used in different ways depending on how the students construct their identities in relation to available subject positions, which are dependent on how students at the same time are "doing" gender and social class. As an example, middle class girls show resistance against SSI-work since the practice is threatening their identity as "successful students". This article uses a sociopolitical perspective in its discussions on inclusion and exclusion in the practice of Vision II. It raises critical issues about the inherited complexity of SSI with meetings and/or collisions between discourses. Even if the empirical results from this qualitative study are situated in specific cultural contexts, they contribute with new questions to ask concerning SSI and Vision II school science.

    Full Text Available Introduction: The consumption of calcium in the Polish population is insufficient, which may negatively influence the occurrence of osteoporosis, as well as cause overweight and obesity. Aim of the research : To analyse the relationship between calcium consumption and body composition of the participants of this study. Material and methods : The study was carried out on a sample group of 103 nursing students. The study group consisted of 91 (88.3% women and 12 (11.7% men, aged from 19 to 33 years. The participants of the study had their body composition analysed, the body mass index (BMI was calculated, and the authors carried out a survey involving the Dairy Products Frequency Questionnaire (ADOS-Ca as well as their own questionnaire to evaluate the socio-economic status of the subjects. Results : The students who had the lowest calcium consumption also had the lowest BMI (p = 0.0015 and the lowest amount of visceral fat (p = 0.0260. Individuals who consumed the lowest amount of calcium also had the lowest muscle mass (p = 0.007 and bone mass (p = 0.004. However, the authors did not notice a significant statistical difference between the level of calcium consumption and the percentage of adipose tissue (p = 0.5000 as well as body water percentage (p = 0.3200. Conclusions: The results of the research do not confirm the hypothesis that high calcium consumption is associated with a lower probability of the occurrence of excess body mass and adipose tissue.

    The effects of acculturation, body perception, and health behaviors on weight status among Vietnamese American students in Houston, Texas were examined for our research. A survey was mailed to 600 randomly selected Vietnamese American students at one university, and 261 complete surveys (response rate, 43.5%) were used for final analyses. Respondents were classified as overweight or normal weight based on the World Health Organization recommended overweight cutoff for Asians (BMI of 23 kg/m(2)). About 32% of respondents were overweight. Men, undergraduate students, and those with an acceptable body perception were more likely to be overweight. Nativity and its interaction with length of US residence were significant predictors of weight status after controlling for other variables. Foreign-born respondents were less likely to be overweight than US-born respondents, but the risk of being overweight with increasing years of US residence was much greater for the foreign-born than for the US-born. The results suggest the need for culturally tailored overweight and obesity prevention programs for Vietnamese Americans.

Therefore, the aim of this study was to ascertain clinical educators’ views on the characteristics that they perceive demonstrate that a student is well prepared for clinical learning. Methods A two round on-line Delphi study was conducted. The first questionnaire was emailed to a total of 636 expert clinical educators from the disciplines of occupational therapy, physiotherapy and speech pathology. Expert clinical educators were asked to describe the key characteristics that indicate a student is prepared for a clinical placement and ready to learn. Open-ended responses received from the first round were subject to a thematic analysis and resulted in six themes with 62 characteristics. In the second round, participants were asked to rate each characteristic on a 7 point Likert Scale. Results A total of 258 (40.56% responded to the first round of the Delphi survey while 161 clinical educators completed the second (62.40% retention rate. Consensus was reached on 57 characteristics (six themes using a cut off of greater than 70% positive respondents and an interquartile deviation IQD of equal or less than 1. Conclusions This study identified 57 characteristics (six themes perceived by clinical educators as indicators of a student who is prepared and ready for clinical learning. A list of characteristics relating to behaviours has been compiled and could be provided to students to aid their preparation for clinical learning and to universities to incorporate within curricula. In addition, the list provides a platform for discussions by professional bodies about the role of placement

    Body mass index (BMI) is known to vary by individual characteristics, but little is known about whether BMI varies by school and by school characteristics. Nationally representative samples of United States schools and students are used to determine the extent to which BMI and percent of students at or above the 85th percentile of BMI vary by school and by school characteristics. Data from the 1991-2004 Monitoring the Future (MTF) study were analyzed in 2006 and 2007. A relatively small proportion of variance in BMI lies between schools; intraclass correlations are on the order of 3%. Still, this is sufficient variation to provide very different environments for students attending schools that are low versus high in average BMI. There is some modest variation by school type (public, Catholic private, non-Catholic private); school size (number of students in the sampled grade); region of the country; and population density. There is more variation as a function of school socioeconomic status (SES) and racial/ethnic composition of the school. School SES in particular was negatively associated with BMI levels, even after controlling individual-level SES and racial/ethnic status. The residual differences in BMI by school suggest that some characteristic of the school and/or community environment--perhaps cultural factors or peer role modeling or differences in school food, beverage, or physical education policies--facilitate obesity in schools with a high concentration of lower socioeconomic students, beyond individual-level factors.

    Background Little is known about the characteristics of mentoring relationships formed between faculty and medical students. Individual mentoring relationships of clinical medical students at Munich Medical School were characterized quantitatively and qualitatively. Methods All students signing up for the mentoring program responded to a questionnaire on their expectations (n = 534). Mentees were asked to give feedback after each of their one-on-one meetings (n = 203). A detailed analysis of the overall mentoring process and its characteristics was performed. For qualitative text analysis, free-text items were analyzed and categorized by two investigators. Quantitative analysis was performed using descriptive statistics and Wilcoxon-test to assess differences in grades between students with and without mentors. Results High-performing students were significantly more likely to participate in the mentoring program (pmentors as counselors (88.9%), providers of ideas (85.0%), and role models (73.3%). Mentees emphasized the positive impact of the mentoring relationship on career planning (77.2%) and research (75.0%). Conclusions Medical students with strong academic performance as defined by their grades are more likely to participate in formal mentoring programs. Mentoring relationships between faculty and medical students are perceived as a mutually satisfying and effective instrument for key issues in medical students’ professional development. Practical implications Mentoring relationships are a highly effective means of enhancing the bidirectional flow of information between faculty and medical students. A mentoring program can thus establish a feedback loop enabling the educational institution to swiftly identify and address issues of medical students. PMID:22989620

    2017-06-01

    Full Text Available The aim of this research was to investigate parent, student and teacher opinions about which characteristics of gifted students should be developed in cognitive, affective, psychomotor and social learning areas. The participants included 609 gifted students, 350 parents and 157 teachers from Science and Art Canters. Participants were surveyed using “The Which Characteristics of Gifted Students Should Be Developed”. The results of research revealed that students, parents and teachers agreed that social and affective skills should be improved. On the other hand, they held different opinions on the importance of music, art, dance, role-play, sport, domestic economy skills. This result indicates that these skills are thought by participants to be less important for gifted students’ development. In addition, teachers did not think technology so important for the development of gifted students, placing more emphasis on cognitive and affective domains.

    In this paper, an inhomogeneous human body model was presented to investigate the propagation characteristics when the human body was used as an antenna to achieve signal transmission. Specifically, the channel gain of four scenarios, namely, (1) both TX electrode and RX electrode were placed in the air, (2) TX electrode was attached on the human body, and RX electrode was placed in the air, (3) TX electrode was placed in the air, and RX electrode was attached on the human body, (4) both the TX electrode and RX electrode were attached on the human body, were studied through numerical simulation in the frequency range 1 MHz to 90 MHz. Furthermore, the comparisons of input efficiency, accepted efficiency, total efficiency, absorption power of human body, and electric field distribution of different distances of four aforementioned scenarios were explored when the frequency was at 44 MHz. In addition, the influences of different human tissues, electrode position, and the distance between electrode and human body on the propagation characteristics were investigated respectively at 44 MHz. The results showed that the channel gain of Scenario 4 was the maximum when the frequency was from 1 MHz to 90 MHz. The propagation characteristics were almost independent of electrode position when the human body was using as an antenna. However, as the distance between TX electrode and human body increased, the channel gain decreased rapidly. The simulations were verified by experimental measurements. The results showed that the simulations were in agreement with the measurements.

    This study investigated characteristics of medical teachers who have adopted student-centered teaching methods into their teaching. A 24-item questionnaire consisted of respondent backgrounds, his or her use of student-centered teaching methods, and awareness of the school's educational objectives and curricular principles was administered of faculty members at a private medical school in Korea. Descriptive statistics and chi-square analysis were conducted to compare faculty use of student-centered approaches across different backgrounds and awareness of curricular principles. Overall response rate was 70% (N=140/200), approximately 25% (n=34) of whom were using student-centered teaching methods. Distributions in the faculty use of student-centered teaching methods were significantly higher among basic sciences faculty (versus clinical sciences faculty), with teaching experiences of over 10 years (versus less than 10 years), and who were aware of the school's educational objectives and curricular principles. Our study indicates differences in medical faculty's practice of student-centered teaching across disciplines, teaching experiences, and their understanding of the school's educational objectives curricular principles. These findings have implications for faculty development and institutional support to better promote faculty use of student-centered teaching approaches.

    This study investigated associations between eating regulation behaviors and body mass index (BMI), weight, and percent body fat in male and female students over the first two years of college. Subjects included 328 college students (215 females and 113 males). Height and weight (via standard techniques), body composition (via bioelectrical impedance analysis), and eating regulation behaviors (using the Regulation of Eating Behavior Scale) were conducted two to three times during both the freshman and sophomore years. Significant associations between eating regulation and BMI, weight, and/or percent body fat were shown mostly in females. In females, higher BMI, weight, and/or percent body fat at the end of the second year of college were found in those with low levels of autonomous, intrinsic motivation, and identified regulation, and high levels of amotivation, while lower BMI, weight, and/or percent body fat were associated with high levels of autonomous, intrinsic motivation, and identified regulation, and low levels of amotivation. The findings that specific eating behaviors in females during the first two years of college influence BMI, weight, and/or percent body fat may be useful for inclusion in university programs focused on college student health to help decrease the risk of obesity and disordered eating/eating disorders in female college students.

    Stealing is a fairly common behaviour among young adults. Understanding the potential associations and characteristics of individuals who steal may help educational institutions, health services and young people themselves resolve difficulties before the behaviour impacts on their academic performance and health. We aim to test the hypothesis that desires to steal among students would be associated with worse academic achievements and higher rates of mood and impulse control disorders. One thousand eight hundred and five students completed the College Student Computer User Survey online and were included in this analysis at a large Midwestern United States University. Responders were grouped according to self-reported stealing urges and behaviours and were compared on measures of psychosocial function, mental health disorders and impulsivity. Urges to steal were associated with worse depressive symptoms, higher levels of perceived stress and a number of psychiatric disorders including bipolar disorder and multiple disorders of impulse control (kleptomania, compulsive sexual behaviour, skin picking, trichotillomania and compulsive buying). CONCLUSIONS AND IMPLICATIONS FOR PRACTICE AND/OR FUTURE RESEARCH: These following data indicate that stealing for many college students may be considered within a spectrum of impulsive behaviours. • Illegal behaviours among students point to mental health difficulties among them. • Our findings may provide clinicians, researchers and health professionals with a clearer picture of a range of impulsive behaviours among college students and promote treatment for this group. • Our findings could also inform preventative approaches to impulsive problems in young adults.

    The aim of this study was to determine the type of medial longitudinal arch (MLA) in students of Krakow universities, investigate the relationship between physical activity and the shaping of the feet, and examine the relationship between hallux valgus angle and the type of footwear chosen most often. The study group consisted of 120 students, of which 56 respondents were students of the University School of Physical Education in Krakow, whereas the remaining 64 respondents were students of the Pedagogical University of Krakow. To evaluate the MLA, a podoscope was used, which allowed us to determine the length and width of the foot, and calculation of the Clarke angle, heel angle γ, and the angle of hallux valgus. All students were also subjected to a measurement of body weight and height. There was a statistically significant relationship between physical activity and the Clarke angle in the group of women studying at the University School of Physical Education. There was no correlation between the hallux valgus angle and the type of footwear chosen most often in the research groups. The most frequently diagnosed type of longitudinal and transverse arch foot in the research group was normal MLA. There was no relationship between physical activity and transverse arch foot in any of the research groups.

    The aim was to examine main reasons for students' medical school choice and their relationship with students' characteristics and motivation during the students' medical study. In this multisite cross-sectional study, all Year-1 and Year-4 students who had participated in a selection procedure in one of the three Dutch medical schools included in the study were invited to complete an online survey comprising personal data, their main reason for medical school choice and standard, validated questionnaires to measure their strength of motivation (Strength of Motivation for Medical School-Revised) and autonomous and controlled type of motivation (Academic Self-regulation Questionnaire). Four hundred seventy-eight students participated. We performed frequency analyses on the reasons for medical school choice and regression analyses and ANCOVAs to study their associations with students' characteristics and motivation during their medical study. Students indicated 'city' (Year-1: 24.7%, n=75 and Year-4: 36.0%, n=52) and 'selection procedure' (Year-1: 56.9%, n=173 and Year-4: 46.9%, n=68) as the main reasons for their medical school choice. The main reasons were associated with gender, age, being a first-generation university student, ethnic background and medical school, and no significant associations were found between the main reasons and the strength and type of motivation during the students' medical study. Most students had based their medical school choice on the selection procedure. If medical schools desire to achieve a good student-curriculum fit and attract a diverse student population aligning the selection procedure with the curriculum and taking into account various students' different approaches is important.

  19. Role of Pre-Course Student Characteristics on Student Learning in Interactive Teaching Environments

    Miller, Kelly Anne

    The goal of this dissertation is to broaden our understanding of interactive teaching strategies, in the context of the introductory physics classroom at the undergraduate level. The dissertation is divided into four main projects, each of which investigates a specific aspect of teaching physics interactively. All four projects look towards improving the effectiveness of interactive teaching by understanding how pre-course student characteristics affect the way students learn interactively. We first discuss lecture demonstrations in the context of an interactive classroom using Peer Instruction. We study the role of predictions in conceptual learning. We examine how students' predictions affect what they report having seen during a demonstration. We also examine how student predictions affect what they recall as the outcome of the demonstration at the end of the semester. We then analyze student response patterns to conceptual questions posed during Peer Instruction. We look at the relationship between a student's tendency to switch their answer and pre-course student characteristics like science self-efficacy. Next we elucidate response timing to conceptual questions posed over the course of the semester, in two introductory physics classes taught using Peer Instruction. We look at the relationship between student response times and student characteristics like pre-course physics knowledge, science self-efficacy and gender. We study response times as a way of gaining insight into students thinking in Peer Instruction environments as well as to improve the implementation of Peer Instruction. Finally, we present work on the role of NB, an online collaborative textbook annotation tool, in a flipped, project based, physics class. We analyze the relationship between students' level of online engagement and traditional learning metrics to understand the effectiveness of NB in the context of flipped classrooms. We also report the results of experiments conducted to

  2. Body characteristics, [corrected] dietary protein and body weight regulation. Reconciling conflicting results from intervention and observational studies?

    Directory of Open Access Journals (Sweden)

    Mikkel Z Ankarfeldt

    Full Text Available Physiological evidence indicates that high-protein diets reduce caloric intake and increase thermogenic response, which may prevent weight gain and regain after weight loss. Clinical trials have shown such effects, whereas observational cohort studies suggest an association between greater protein intake and weight gain. In both types of studies the results are based on average weight changes, and show considerable diversity in both directions. This study investigates whether the discrepancy in the evidence could be due to recruitment of overweight and obese individuals into clinical trials.Data were available from the European Diet, Obesity and Genes (DiOGenes post-weight-loss weight-maintenance trial and the Danish Diet, Cancer and Health (DCH cohort. Participants of the DCH cohort were matched with participants from the DiOGenes trial on gender, diet, and body characteristics. Different subsets of the DCH-participants, comparable with the trial participants, were analyzed for weight maintenance according to the randomization status (high or low protein of the matched trial participants.Trial participants were generally heavier, had larger waist circumference and larger fat mass than the participants in the entire DCH cohort. A better weight maintenance in the high-protein group compared to the low protein group was observed in the subgroups of the DCH cohort matching body characteristics of the trial participants.This modified observational study, minimized the differences between the RCT and observational data with regard to dietary intake, participant characteristics and statistical analysis. Compared with low protein diet the high protein diet was associated with better weight maintenance when individuals with greater body mass index and waist circumference were analyzed. Selecting subsets of large-scale observational cohort studies with similar characteristics as participants in clinical trials may reconcile the otherwise conflicting

    While solving physics problem particularly in force matter, it is needed to have the ability of constructing free body diagrams which can help students to analyse every force which acts on an object, the length of its vector and the naming of its force. Mix method was used to explain the result without any special treatment to participants. The participants were high school students in first grade totals 35 students. The purpose of this study is to identify students' ability level of constructing free body diagrams in solving restricted and structured response items. Considering of two types of test, every student would be classified into four levels ability of constructing free body diagrams which is every level has different characteristic and some students were interviewed while solving test in order to know how students solve the problem. The result showed students' ability of constructing free body diagrams on restricted response items about 34.86% included in no evidence of level, 24.11% inadequate level, 29.14% needs improvement level and 4.0% adequate level. On structured response items is about 16.59% included no evidence of level, 23.99% inadequate level, 36% needs improvement level, and 13.71% adequate level. Researcher found that students who constructed free body diagrams first and constructed free body diagrams correctly were more successful in solving restricted and structured response items.

    This study was done to investigate the relationship between the perception of body image, body weight satisfaction or dietary behavior and self-rated health status in Korean college students. Subjects, 285 college students, were divided into three groups (healthy, normal, and unhealthy) according to the answer for the self-rated health question. Information about demographic status, self-rated health condition, height and weight, perception of body image, satisfaction of body weight, concern for body weight control, dietary behavior, nutritional knowledge, and health-related characteristics collected by a self-reported questionnaire. The proportion of men and women in each group was not significantly different. The academic year, major, experience of nutritional education, and type of residence were not significantly related with self-rated health but the pocket money range was significantly associated (ppocket money range and was increased in less than 210 thousand won or over 300 thousand won pocket money ranges. There were no significant differences for age, height, weight and BMI between the groups. The body image perception and body weight satisfaction levels of healthy group was significantly higher than those of unhealthy group (p<0.01 and p<0.001, respectively), but the level of concern for body weight control in healthy subjects was significantly lower than that in unhealthy subjects (p<0.05). The proportion of subjects reported as healthy was significantly increased with increased frequencies of following food behaviors; weekly use of protein foods (p<0.01), vegetables (p<0.05) and dairy products (p<0.01), and food habits such as "regularity of meal time" (p<0.01), "eating in moderation" (p<0.05), and "eating breakfast" (p<0.001). Overall results suggested that the college students have tended to have a better perception of health when they have better body image perception, body weight satisfaction and dietary behaviors.

    This study aimed to assess body mass index (BMI) of nursing students, and examine the links between health behavior in terms of healthy dietary habits, positive health habits, dieting and BMI. A structured questionnaire was used for obtaining information on dietary habits, positive health habits, demographic characteristic including body weight, and height by administering self-answering questionnaires to all of nursing students in the 1st, 2nd, 3rd, and 4th year-classes of the College of Nursing located in northeast Thailand. Three hundred and eleven female nursing students with an average age of 19.9 (SD = 1.4), had an average BMI of 20.3 kg/m2 (SD = 1.9). Most of the subjects (82.6%) were in the acceptable weight category (BMI > 18.5-24.99 kg/m2), 5.1% underweight (BMI or = 25.0 kg/m2). About half of them (50.8-66.2%) practiced healthy dietary habits in terms of avoiding eating fat/cholesterol, enriched fiber foods, while one-fourth practiced daily fruit consumption. Positive health habits in terms of having breakfast, and taking exercise over the last two weeks, were practiced by 49.5% and 59.8%, respectively. Persistent health problem occurred 13.5% amongst the subjects. The univariate analyses revealed significant associations between dieting with the BMI; perception of body size with the BMI; the enriched fiber food consumption with dieting; and the avoidance of fat/cholesterol with dieting. It suggests that the choice of food was predominantly attributable to dieting. Results from multiple logistic regression analysis showed that dietary belief, dieting, and exercise had effects on the strength of the association (p = 0.0191, 0.0024, 0.0165; Odds ratios = 0.97, 2.21, 1.87, respectively). The results and implications are discussed.

    The aim of this study was to compare the anthropometry, upper-body strength, and lower-body power characteristics in elite junior, sub-elite senior, and elite senior Australian Football (AF) players. Nineteen experienced elite senior (≥4 years Australian Football League [AFL] experience), 27 inexperienced elite senior (free soft tissue mass [FFSTM], fat mass, and bone mineral content) with dual-energy x-ray absorptiometry, upper-body strength (bench press and bench pull), and lower-body power (countermovement jump [CMJ] and squat jump with 20 kg). A 1-way analysis of variance assessed differences between the playing levels in these measures, whereas relationships between anthropometry and performance were assessed with Pearson's correlation. The elite senior and sub-elite senior players were older and heavier than the elite junior players (p ≤ 0.05). Both elite playing groups had greater total FFSTM than both the sub-elite and junior elite players; however, there were only appendicular FFSTM differences between the junior elite and elite senior players (p squat performance measures (r = 0.33-0.55). Australian Football players' FFSTM are different between playing levels, which are likely because of training and partly explain the observed differences in performance between playing levels highlighting the importance of optimizing FFSTM in young players.

    Background The purpose of this study was to use the body painting method to teach hand anatomy to a group of preclinical medical students. Methods Students reviewed hand anatomy using the traditional method and body painting exercise. Feedback and retention of the anatomy-related information were examined by a questionnaire and multiple-choice questions, respectively, immediately and 1 month after the painting exercise. Results Students agreed that the exercise was advantageous and helped facilitate self-active learning after in-class anatomy lessons. While there was no significant difference in knowledge retention between the control and experimental groups, the students appreciated the exercise in which they applied body paint to the human body to learn anatomy. Conclusion The body painting was an efficient tool for aiding the interactive learning of medical students and increasing the understanding of gross anatomy.

    The authors examined characteristics of body dysmorphic disorder in the largest sample for which a wide range of clinical features has been reported. The authors also compared psychiatrically treated and untreated subjects. Body dysmorphic disorder usually began during adolescence, involved numerous body areas and behaviors, and was characterized by poor insight, high comorbidity rates, and high rates of functional impairment, suicidal ideation, and suicide attempts. There were far more similarities than differences between the currently treated and untreated subjects, although the treated subjects displayed better insight and had more comorbidity. PMID:16000674

    Full Text Available This study investigated the desirable educational background for a teacher to work with high ability/gifted students, desirable characteristics these teachers should present and conceptions on high ability/giftedness. The participants were 20 public school teachers from a city surrounding Brasilia. Of this group, ten were elementary school teachers working with initial grades and ten were undergraduate Pedagogy teachers. A qualitative approach was used and data were collected by means of a semi-structured interview. A content analysis was then conducted. In relation to the desirable educational background for a teach of high ability/gifted students, participants indicated the need of continuous training, under graduation curriculum adapted to the theme and graduation courses in the area. The desirable features for teachers of high ability/gifted students were related to personological attributes (personality traits and intellectual ability, as well as professional characteristics. The conceptions on high ability/giftedness presented by the participants were, in general, close to those found in the literature and used as reference for this study. However, there was lack of information on how to apply the theory into real practice, as well as several wrong ideas on the topic.

    Full Text Available The aim of the present research is to present a 16-segmental biomechanical model of the Bulgarian male to determine the mass-inertial characteristics of the body of the Bulgarian male based on parameters available in the literature and its 3D generation within SolidWorks software. The motivation of the research is to support mainly sport, rehabilitation, wearable robots and furniture design users. The proposed CAD model of the human body of men is verified against the analytical results from our previous investigation, as well as through comparison with data available in the provided references. In this paper we model two basic human body positions: standing position and sitting with thighs elevated. The comparison performed between our model results and data reported in literature gives us confidence that this model can be reliably used to calculate the mass-inertial characteristics of male body at any postures of the body that is of interest. Therefore, our model can be used to obtain data for positions which the human body has to take in everyday live, in sport, leisure, including space exploration, for investigating criminology cases – body fall, car crash, etc. The model is suitable for performing computer simulation in robotics, medicine, sport and other areas.

    Increasing public concern about human exposure to electromagnetic fields led to the development of International Exposure Standards, which reflect the actual scientific knowledge on this subject. Existing exposure limits (reference levels), are based on maximum admissible fields or induced currents densities inside human bodies, called basic restrictions. Since those physical quantities can not be readily measured, they must be estimated using techniques of computational dosimetry. These techniques rely on accurate computational modelling of human bodies to establish the relation of external field (electric / magnetic) to induced current (internal field). Nowadays the models available for human body simulation (FEM, FDM,...) are quite accurate, specially when using geometric discretization obtained from medical imaging techniques, however the determination of tissues characteristics (permittivity and conductivity) is still an issue to be dealt with. In current studies the electrical characteristics (permittivity and conductivity) of body tissues are based on values which were obtained from measurements done on tissue simples obtained from dead bodies. However those values may not represent adequately the behaviour of living tissues. In this paper a research designed to characterize the permittivity of human body tissues is presented, consisting of measurements and simulations designed to determine, using indirect methods, the electrical behaviour of living tissues. A study of exposure assessment on a real high voltage transmission line in Brazil, using measured permittivity values combined with a finite element model of the human body is presented in the panel.

    Aim This study clarified the characteristics of life habits of obese Japanese male students at the National Colleges of Technology, Japan. Materials and methods Healthy students aged 15-19 years answered a questionnaire containing 21 items on the following five categories of life habits: general exercise, meals, sleeping, leisure activity and illness or injury history. The subjects were divided into three groups based on the criteria of body mass index (BMI) and body fat percentage (%BF): non-obese (%BF time, bedtime and amount of time spent walking, sleeping and watching TV per day were examined using one-way analysis of variance (ANOVA) and chi-square tests for each item. Results The overweight obese and hidden obese groups engaged in less exercise time, were more likely to eat until they were full at meals and were less likely to eat between meals or late at night than the non-obese group. In addition, the non-obese group had significantly later waking times and significantly less TV-watching time than the overweight obese group. There were no significant differences with respect to leisure activity and illness or injury history among the three groups. Many students in all groups had regular waking times and were not performing any leisure activities. Conclusion The findings suggest that obese students may need further guidance to help them maintain a healthy life and appropriate weight.

    Medical students' personality types and interpersonal needs must be considered. The purpose of this study was to examine the characteristics of personality types and interpersonal needs. A total of 171 students in Konyang University College of Medicine were examined using the Myers-Briggs Type Indicator (MBTI) and Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B). The data were analyzed by frequency analysis, t-test, and one-sample proportion test. The proportion of the 4 pairs of MBTI dimensions were Extroversion (E)-Introversion (I) (53.2% vs. 46.8%), Sensing (S)-Intuition (N) (63.2% vs. 36.8%), Thinking (T)-Feeling (F) (59.7% vs. 40.4%), and Judging (J)-Perceiving (P) (56.1% vs. 43.9%). The predominant personality types were ISTJ (16.4%), ESTJ (14.0%), and ESFJ (10.5%). The level of interpersonal needs were medium rage that was inclusion (mean=8.1), control (mean=8.8), affection (mean=8.1), expressed behavior (mean=12.1), wanted behavior (mean=12.9), and overall interpersonal needs (mean=25.0). Of the basic social needs, males and females differed significantly with regard to control needs (p=0.028). Educational programs that take into account personality types and characteristics of interpersonal needs are crucial in providing effective medical education. Our results suggest that the characteristics of personality types and interpersonal needs should be considered in developing an interpersonal relations improvement program for medical students.

    2015-09-01

    The purpose of this study was to examine relationships among bodybuilding dependence, muscle satisfaction, body image-related quality of life and body image-related coping strategies, and test the hypothesis that muscle dysmorphia characteristics may predict quality of life via coping strategies. Participants (294 males, Mage=20.5 years, SD=3.1) participated in a cross-sectional survey. Participants completed questionnaires assessing muscle satisfaction, bodybuilding dependence, body image-related quality of life and body image-related coping. Quality of life was correlated positively with muscle satisfaction and bodybuilding dependence but negatively with body image coping (P<0.05). Body image coping was correlated positively with bodybuilding dependence and negatively with muscle satisfaction (P<0.05). Mediation analysis found that bodybuilding dependence and muscle satisfaction predicted quality of life both directly and indirectly via body image coping strategies (as evidenced by the bias corrected and accelerated bootstrapped confidence intervals). These results provide preliminary evidence regarding the ways that muscularity concerns might influence body image-related quality of life. Copyright © 2014 Sports Medicine Australia.

    This study examined differences in body-related shame, guilt, pride, and envy based on intrapersonal characteristics of sex, age, and weight status in 527 Canadian adults. Compared to men, women reported significantly higher shame and guilt contextualized to the body. No sex differences were observed for envy or pride. Middle-aged adults reported higher shame and lower pride compared with young adults, whereas no age differences were observed with body-related guilt. Meanwhile, shame and guilt were highest for individuals who had overweight or obese weight status, and pride was highest in individuals with average weight status. Overall, effect sizes were small and there were no significant interaction effects between sex, age, and weight status across body-related emotions. Further research is needed to capture similarities and differences of body-related self-conscious emotions between intrapersonal characteristics, to aid the development of intervention strategies to manage this important dimension of body image.

    Limited research has quantified variation in the characteristics of the breasts among women and determined how these breast characteristics are influenced by age and body mass. The aim of this study was to classify the breasts of women in the community into different categories based on comprehensive and objective measurements of the characteristics of their breasts and torsos, and to determine the effect of age and body mass index (BMI) on the prevalence of these breast categories. Four breast characteristic clusters were identified (X-Large, Very-ptotic & Splayed; Large, Ptotic & Splayed; Medium & Mildly-ptotic; and Small & Non-ptotic), with age and BMI shown to significantly affect the breast characteristic clusters. These results highlight the difference in breast characteristics exhibited among women and how these clusters are affected by age and BMI. The breast characteristic clusters identified in this study could be used as a basis for future bra designs and sizing systems in order to improve bra fit for women.

    The aim of the present study was to examine the disordered eating attitudes and sociocultural body ideals internalization among university athletes (N.=98), exercisers (N.=125) and sedentary (N.=81) undergraduate female students. The mean age (SD) of the sample was 20.17 (2.00). The students completed Eating Attitude Test - 26, Body Areas Satisfaction subscale of the Multidimensional Body-Self Relations Questionnaire, Body Shame subscale from the Objectified Body Consciousness Scale, Rosenberg Self- Esteem Scale, Appearance subscale from the Motives for Physical Activity Measure--Revised, reported their physical activity and fluid manipulation-related behaviour. We observed no significant differences in disordered eating, body dissatisfaction, self-esteem and fluid manipulation-related behaviour among athletes, exercisers and sedentary female students. Body shame predicted disordered eating in all groups of women. Students high in body shame reported higher levels of disordered eating, body dissatisfaction, appearance-related exercise motives, fluid manipulation-related behaviour and lower self-esteem, regardless of their physical activity level. The results show that internalization of the sociocultural body standards provide a mechanism through which different physical activity levels are associated with negative eating and physical activity-related outcomes in college-aged women.

    Freshmen women (N = 240) at the State University of Campinas (UNICAMP) in the state of Sao Paulo, Brazil responded to a questionnaire concerning several aspects of their sexuality from the beginning of adolescence. Topics such as body changes during puberty, menarche, menstruation, masturbation, sexual identity, virginity, sexual relations, maternity, contraceptives, abortion, and attitudes toward AIDS were investigated, as well as the level and sources of information about sex and the quality of the subjects' relationships with their parents. The majority of the subjects revealed satisfactory development in most of the aspects surveyed, as well as in their relationships with their parents except where sexual issues were concerned. Nevertheless, most of the students reported menstrual disturbances, and a significant number of the sexually active reported inappropriate behavior in relation to contraception and AIDS prevention. The results of the research are analyzed using psychodynamic theories of sexual development.

Methods: In this experimental study, vibration characteristics were measured according to the ISO2631-1 with each of the statuses: tubeless tires fixed and fluid in it (normal air or nitrogen and also the fluid in the tires fixed with tubes or tubeless on asphalt-paved road. Other variables including tire pressure, engine speed, road gradient, number of passengers, springs, and shock absorbers were kept constant. Then the effect of changes was analyzed using an appropriate statistical test. Results: After changing nitrogen to normal air and tubeless tires to tube, the average of RMS in Z-axis, eight-hour equivalent acceleration A(8 and crest factor were reduced (P 0.9 m/s2 to caution zone (0.45-0.9 m/s2 with a value of 0.8 m/s2. Conclusions: The amount of vibration transmitted to the whole body is sensitive to existence of tubes and tires inflation so that we can reduce the amount of whole-body vibration to lower than the upper limit of the health risk by changing the characteristics of the tire

    The objectives of this study were to examine changes in body weight, body mass index (BMI), body composition, and shape in a group of male and female students over the 4-year college period. Anthropometric assessments including height and weight (via standard techniques), body composition (via bioelectrical impedance analysis), and body shape (via 3-dimensional body scanning) were conducted at the beginning of the freshman year and end of the senior year in 131 college students. Four-year changes included significant (p obese increased from 18% to 31%. The number of females and males with ≥30% and 20% body fat, respectively, increased from n = 14 to n = 26 (with n = 4 exhibiting normal weight obesity) over the 4-year period. The waist circumference changes were significantly (p obesity and normal weight obesity among this college population suggests the need for additional health promotion strategies on college campuses.

    Dyslexia is the most common subtype of learning disabilities with a prevalence ranging from 5-10 per cent. The central difficulty in dyslexia is the phonological awareness deficit. The authors have developed a screening test to assess the reading ability of Thai primary school students. 1. To study the prevalence of dyslexia in first to sixth grade students at Wat Samiannaree School. 2. To study the clinical characteristics such as sex, neurological signs, verbal intelligence and comorbid attention deficit hyperactive disorder (ADHD) of the dyslexia group. A total of 486 first to sixth grade students were administered "Raven's progressive matrices test" for estimation of intellectual functioning. Those who scored below the fifth percentile were labeled as mental retardation and excluded from the study. The students' reading ability was evaluated by 3 steps; first by classroom teachers using some items of the screening test, second by the researchers examining some more items individually, and third by the special educator assessing more details in reading and phonology. The students who had a reading ability two-grade levels below their actual grades and impairment in phonology were diagnosed with dyslexia. The prevalence of dyslexia and probable dyslexia were found to be 6.3 per cent and 12.6 per cent, respectively. The male to female ratio of dyslexia was 3.4:1. The dyslexia group had significantly lower Thai language scores than those of the normal group (p dyslexia group had a normal grossly neurological examination but 90 per cent showed positive soft neurological signs. Mean verbal intellectual quotient score in the dyslexia group assessed by using Wechsler Intelligence Scales for Children--Revised was 76 +/- 7. The comorbid ADHD was 8.7 per cent in the dyslexia group. Dyslexia was a common problem among primary school students in this study. Further studies in a larger population and different socioeconomic statuses are required to determine the prevalence

    Body-art practices are increasing among adolescents and young adults. Although substantial data are available in developed countries, little has been documented about body-art practices in developing countries. To determine the magnitude, types and reasons for practicing body-art practices among undergraduate medical University students in Dar es Salaam, Tanzania. A cross-sectional descriptive study was conducteed among undergraduate University students in Dar es Salaam involving 536 respondents from two Universities. We used a self-administered questionnaire to collect data. Analyses were based on summary measures and bivariate analyses. While 7.5% of undergraduate students reported having tattoos, 20% reported having body puncturing or piercing. Body piercing is reported more among female university undergraduate students than their male counterparts. Reported main reasons for undergoing body-art include "a mark of beauty," 24%, "just wanted one," 18% and "a mark of femininity or masculinity," 17%. The majority (98%) of students were aware that unsafe body-art practices may lead to contracting HIV and more than half (52%) reported awareness of the risk of Hepatitis B infection. Despite high awareness of the potential risks involved in unsafe body arts that include tattoo and piercing, these practices are increasing among adolescents and young adults. There is need to have educational and counseling efforts so as to minimize associated health risks.

    This study examines health perceptions, self and body image, physical exercise and nutrition among undergraduate students. A structured, self-reported questionnaire was administered to more than 1500 students at a large academic institute in Israel. The study population was heterogenic in both gender and fields of academic study. High correlations between health perceptions, appropriate nutrition, and positive self and body image were found. The relationships between these variables differed between the subpopulation in the sample and the different genders. Engagement in physical exercise contributed to positive body image and positive health perceptions more than engagement in healthy nutrition. Nutrition students reported higher frequencies of positive health perceptions, positive self and body image and higher engagement in physical exercise in comparison to all other students in the sample. This study suggests, as have many before, that successful health promotion policy should reflect a collectivist rather than an individualist ethos by providing health prerequisites through a public policy of health-promotion, where the academic settings support a healthy lifestyle policy, by increasing availability of a healthy, nutritious and varied menu in the cafeterias, and offering students various activities that enhance healthy eating and exercise. IMPLICATIONS AND CONTRIBUTION: This study examined health perceptions, self-image, physical exercise and nutrition among undergraduate students and found high correlations between these topics. Nutrition students reported higher frequencies of positive health perceptions, and positive self and body image and engaged more in physical exercise when compared with all other students in the sample.

    Medical and business are one of the most popular majors among students, and both fields require intensive training to reach certain level of expertise. During the development of professionalism, goal can become a crucial role in psychological impetus. The purpose of this study is to compare goal contents, goal characteristics, and effect of goal characteristics on student's major satisfaction between medical and business. A total of 193 undergraduate students (97 medical students, 96 business students) answered survey questions including goal contents, goal characteristics (goal autonomy, goal attainability, social value of goal) and satisfaction on their majors. Qualitative analysis of goal contents and quantitative analysis of goal characteristics, and their effects on student major satisfaction were performed. Goal content analysis showed percentage of social concern goal was higher in medical students (25.8%) than business students (6.3%), whereas percentage of wealth goal was higher business students (24.0%) than medical students (3.1%). Among goal characteristics, goal attainability and social value of goal were higher in medical students than business students. In both groups, social value of goal was significantly predict major satisfaction. Goal contents and goal characteristics are different between medical and business students. Curriculum and educational interventions that concerning students' goal and developing programs to enhance students' social value of goal is necessary.

    This study explored the relationship between adolescents' emotional intelligence and the tendency to develop an eating disorder. Senior high school students in Taiwan were recruited for the study. A 3- part anonymous questionnaire measured demographic information, body weight satisfaction, and expectation of body weight. Students also completed the Adolescent Emotional Intelligence Scale and the Eating Disorders Attitude- 26 Test (EAT-26). Height and weight were also measured. The mean of EAT-26 score was 8.66 ± 7.36, and 8.6% students were at high risk to develop eating disorders. Gender, body weight, body dissatisfaction and the expected body shape were significantly related to disturbed eating attitudes and behaviours. Scores of EAT-26 were positively correlated with emotional perception, emotional expression, and emotional application. Disturbed eating behaviours exist among adolescents in Taiwan, and these behaviours may be related to emotional intelligence. However further studies with larger samples are needed.

    In the present study we used longitudinal methods to examine body image development during the early part of college. Students (N=390; 54% female) who identified as African American (32%), Latino/a American (27%), and European American (41%) completed surveys during their first, second, and third semesters at college. There were overall gender and racial/ethnic differences in all three aspects of body image, and both stability and change in body image development. Female students' appearance evaluation became more positive, whereas male students' appearance evaluation showed no significant change. Individuals' body areas satisfaction increased over time, but remained stable when controlling for BMI. Appearance orientation did not change, and there were no racial/ethnic differences in body image development. Experiences in the college environment may play a role in these trends.

    Introductory physics students have difficulties understanding concepts and solving problems. When they solve problems, they use surface features of the problems to find an equation to calculate a numerical answer often not understanding the physics in the problem. How do we help students approach problem solving in an expert manner? A possible answer is to help them learn to represent knowledge in multiple ways and then use these different representations for conceptual understanding and problem solving. This solution follows from research in cognitive science and in physics education. However, there are no studies in physics that investigate whether students who learn to use multiple representations are in fact better problem solvers. This study focuses on one specific representation used in physics--a free body diagram. A free-body diagram is a graphical representation of forces exerted on an object of interest by other objects. I used the free-body diagram to investigate five main questions: (1) If students are in a course where they consistently use free body diagrams to construct and test concepts in mechanics, electricity and magnetism and to solve problems in class and in homework, will they draw free-body diagrams on their own when solving exam problems? (2) Are students who use free-body diagrams to solve problems more successful then those who do not? (3) Why do students draw free-body diagrams when solving problems? (4) Are students consistent in constructing diagrams for different concepts in physics and are they consistent in the quality of their diagrams? (5) What are possible relationships between features of a problem and how likely a student will draw a free body diagram to help them solve the problem? I utilized a mixed-methods approach to answer these questions. Questions 1, 2, 4 and 5 required a quantitative approach while question 3 required a qualitative approach, a case study. When I completed my study, I found that if students are in an

    University students face academic responsibilities that may produce stress, which may lead to changes in dietary patterns (DPs). These changed patterns can become dysfunctional, often resulting in a negative impact on the health of the stressed student. Little is known about DPs in college students in Puerto Rico (PR). The purpose of this study was to describe the DPs of college students in PR and the association of these patterns with socio-demographic characteristics and perceived academic stress. This retrospective epidemiological study investigated self-reported DPs in a representative sample of 275 college students, in relation to socio-demographic characteristics, body composition (BC), and perceived academic stress; a Diet Quality Index was developed using the USDA Food Patterns for 2010 to determine whether their DPs were adequate or inadequate. Most of the participating students were female (67.6%), ranged from 21 to 30 years old (88%), lived in low household incomes (42.7%), and had healthy weights (56.4%). Most of the students perceived the stress levels as being moderate (60.7%). Most had diets that were below the dietary recommendations for grains, fruits, vegetables, dairy products, and protein, whereas fat consumption was adequate. Overall, most had inadequate DPs (62%). DP was significantly associated with age (p students had better DPs than did younger students. In terms of the different schools (p students from the School of Medicine and those from the School of Public Health had better DPs than did the students from the other schools. DP was not associated with income, gender, BMI, stress level, or course load. The majority of the students had inadequate DPs, which inadequacy was associated with both the age of the student and the school that he or she attended.

    Full Text Available There is substantial evidence that somatotype and success in sport and physical performance are positively related. Existing somatotype data on athletes are useful as guidelines for sport selection and choice of training appropriate to the enhancement of desired somatotype characteristics. Updated somatotype data from non-athlete reference groups complement comparative analysis applied in assessing the effects of the training process and selection. The aim of this study was to determine the somatotype of untrained girls studying at Warsaw University of Technology in 2011, in order to create a current reference group for comparison, and to investigate the difference in body build of female volleyball players compared with the non-athlete group. Twelve Second Division female volleyball players (age 21.6±1.5 years, body height 177.3±6.2 cm, body mass 71.0±6.5 kg, training experience 8.4±3.4 years and 150 female untrained students of the University of Technology in Warsaw (age 20.0±6.4 years, body height 166.5±6.4 cm, body mass 59.7±8.4 kg participated in a study carried out in 2011. Somatotype was determined using the Heath-Carter method. The volleyball players were a little older and were significantly taller and heavier than female students (p<0.05. Significant differences between the groups were found in breadth of the elbow, breadth of the wrist, biacromial diameter, arm circumference and crus circumference (p<0.05. The mean somatotype of the volleyball players was 4.5-3.4-2.8. (4.5±1.0-3.4±1.2-2.8±1.3, whilst that of the untrained students was 5.1-3.6-2.8. (5.1±1.4-3.6±1.1-2.8±1.3; the groups did not differ significantly in somatotype. The groups were significantly different in body composition (F [kg] and LBM [kg], as estimated by BIA and anthropometric methods (p<0.05. No differences were observed between the groups in the skinfolds. Morphological characteristics of the female volleyball players depended on the competition level

    This study was undertaken to determine the effect of four commercial probiotics on growth, body characteristics and haematological parameters of ostrich chicks. A total of 25 ostrich chicks (937±68.1 g) were individually allocated and fed the experimental diet for six weeks (n=5 per treatment). Experimental diets consisted of a corn/soybean meal-based diet unsupplemented (T1: Control), and four diets supplemented with probiotics according to the recommendations of the manufacturer (T2: 0.04% Bioplus 2B; T3: 0.09% Primalac; T4: 0.1% Thepax; and T5: 0.03% Protexin). Feed intake (FI), body weight (BW) and seven body characteristics (e.g. height) were measured every week. Blood samples and other body characteristics were also taken in the last week. There was an interaction effect between diet and time on all the growth variables and body characteristics (p<0.05). Both the BW and the BW gain of the ostrich chicks were, in general, higher for those fed the diet T2 than those fed the control diet (0.42, 1.07, 0.99, 1.09, 2.51, and 1.66 kg BW gain vs 0.28, 0.41, 0.83, 0.94, 1.15, and 1.15 kg BW gain at 7, 14, 21, 28, 35, and 42 days respectively), while for those fed the other diets containing probiotics differences were only observed at 42 days (p<0.05). Consuming probiotics over an extended period influenced several of the haematological parameters differently compared to those fed the control diet (p<0.05). T2 and T3 increased the concentration of total cholesterol (157 and 210 mg/dL respectively), when compared to those fed the control diet (119 mg/dL), while total cholesterol was slightly reduced (p>0.05) for those fed the diet containing Thepax (T4, 79 mg/dL). In conclusion, the effects of commercial probiotics on growth performance, body characteristics and haematological parameters varied among probiotics. (Author)

    Full Text Available The results of the interaction between coal failure and mining pressure field evolution during mining are presented. Not only the mechanical model of stope and its relative structure division, but also the failure and behavior characteristic of coal body under different mining stages are built and demonstrated. Namely, the breaking arch and stress arch which influence the mining area are quantified calculated. A systematic method of stress field distribution is worked out. All this indicates that the pore distribution of coal body with different compressed volume has fractal character; it appears to be the linear relationship between propagation range of internal stress field and compressed volume of coal body and nonlinear relationship between the range of outburst coal mass and the number of pores which is influenced by mining pressure. The results provide theory reference for the research on the range of mining-induced stress and broken coal wall.

    The configurations analyzed are half-axisymmetric, power-law bodies surmounted by thin, flat wings. The wing planform matches the body shock-wave shape. Analytic solutions of the hypersonic small disturbance equations form a basis for calculating the longitudinal aerodynamic characteristics. Boundary-layer displacement effects on the body and the wing upper surface are approximated. Skin friction is estimated by using compressible, laminar boundary-layer solutions. Good agreement was obtained with available experimental data for which the basic theoretical assumptions were satisfied. The method is used to estimate the effects of power-law, fineness ratio, and Mach number variations at full-scale conditions. The computer program is included.

    Full Text Available In this work it was aimed to evaluate Pearson correlations between body measurements, carcass characteristics and production of 35 Nellore bulls, confined for 96 days, with 402±14.90 kg and 18 months old. Weightings, ultrasound images and 14 measurements were obtained at the beginning of each experimental period and before slaughter, totaling four weight ratings of ultrasound images and measurements per animal. For the evaluation of body measurements and ultrasound images with carcass traits the values from the last measurement were considered. The images were made along with weighing animals through a Scanner, and measurements with a tape measure and a zoométrica cane, and these were correlated with each other and with productive and carcass characteristics. For measures of loin eye area evaluated by ultrasonography, it were found positive correlations with body length (0.32, rump (0.36 and thigh (0.20; withers height (0.20 and pelviano contour (0.38 (P<0.05. Variables of hip height and chest, chest width and pin bones, and heart girth showed positive correlations with two or more productive traits of economic interest, such as slaughter weight, hot carcass weight and dressing percentage (P<0.05. Significant correlations were found for most of the variables studied. Linear body measurements such as length and height emerge as a tool that can be useful in the formation of more homogenous lots and to predict the point of slaughter, along with the weight of the animals.

    Previous reports of foreign-body ingestions focused primarily on accidental ingestions. To describe the characteristics and management of foreign-body ingestions, with predominantly intentional ingestion, in a lower socioeconomic status population. A retrospective case series. An urban county hospital. Patients >/=17 years old, with foreign-body ingestions between 2000 and 2006. Characteristics of ingestion cases, endoscopic extraction, need for surgery, and complications. Among 262 cases, 92% were intentional, 85% involved psychiatric patients, and 84% occurred in patients with prior ingestions. The time from ingestion to presentation was >48 hours in 168 cases (64%). The overall success rate for endoscopic extraction was 90% (165/183 cases). Surgery was performed in 30 cases (11%) and was more common for objects beyond the pylorus versus objects above the pylorus (16/43 [37%] vs 10/151 [7%], respectively) and in cases with a greater delay from ingestion to presentation (25/168 [15%] if >48 hours vs 4/77 [5%] if 48 hours vs 14/165 [8%] if body ingestions in an urban county hospital occurred primarily in psychiatric patients who had repeated episodes of intentional ingestions. Endoscopic extraction was unsuccessful in 10% of cases. Long delays from ingestion to presentation and intervention may account for relatively high rates of surgery and perforation. Strategies to prevent ingestions and delays in endoscopic management are needed in this population.

    Full Text Available The aim of this study was to examine the relationship between body type, self-esteem and assertiveness among adolescents of ages between 13 and 19 years. To achieve this aim, the study sampled 56 male and 94 female adolescents of the Senior High School in Accra, Ghana. Results showed that, higher self-esteem leads to assertiveness. Results also showed that body type perception affects self-esteem. It is, therefore, recommended that Guidance and Counselling officers in our schools should educate adolescent students on the three body types and the advantages associated with being one of these body types. This may help prevent developing body dysmorphic disorder, low self-esteem and non-assertiveness among students with negative perceptions of their body types and the possible effects on their personal relationships with peers, general academic performance and in- school and out-of- school life.

    Full Text Available This is a study of the relationships between the student-body composition of the school, some characteristics of the scholastic process—culture and school climate—according to learners’ perceptions, and the mathematics achievement of students in the last year of high school in Argentina. The data used came from the 1998 National Census of High School Completion, carried out by the nation’s Ministry of Culture and Education. The file contains data for 135,000 students of 2,708 schools in 25 states. Multilevel linear modeling with three levels (student, school and state was applied. A strong relationship was detected between mathematics achievement and the variables student-body composition and school process. When both variables acted together, the effect of other variables experienced a pronounced descent. Although reduced, the variables of the process influenced the student’s achievement. There was identified for future works a reference model which would evaluate other institutional learning factors.

    Intuitive eating, which can be defined as reliance on physiological hunger and satiety cues to guide eating, has been proposed as a healthy weight management strategy. To date, there has not been a published study on intuitive eating in the context of Malaysia. Therefore, this cross-sectional study aims to determine associations between body weight status, psychological well-being and disordered eating behaviors with intuitive eating among undergraduate university students. A total of 333 undergraduate respondents (21.3% males and 78.7% females) from three randomly selected faculties in a public university in Malaysia participated in this study. Respondents completed a self-administered questionnaire which featured socio-demographic characteristics, intuitive eating, self-esteem, body appreciation, general unconditional acceptance, body acceptance by others, body function and disordered eating. Body weight, height, body fat percentage and waist circumference were measured. The results from this study revealed that there was no difference (t = 0.067, p = 0.947) in intuitive eating scores between males (75.69 ± 7.16) and females (75.62 ± 7.90). Multiple linear regression results have shown that body appreciation (β = 0.385, p < 0.001) and disordered eating (β = -0.168, p = 0.001) were significant predictors of intuitive eating, which accounted for 19.6% of the variance in intuitive eating. Health promotion programs should highlight the importance of enhancing body appreciation and preventing disordered eating behaviors among university students in order to promote intuitive eating as one of the healthy weight management approaches.

    Purpose The present study investigated the influence of peers’ and family members’ body shapes on the perception of body image and desire for thinness in Japanese female students. Methods The study included 342 female, Japanese university students between the ages of 18 years and 22 years. They completed an anonymous questionnaire, which included questions related to anthropometry and body perception. Eating behavior was assessed by the Japanese version of the Eating Attitude Test-26. Results Many students overestimated their body shape (81.2% of underweight students and 74.6% of normal students) and had a desire for thinness (41.0% of underweight students, 88.2% of normal students, and 100% of overweight students). One of the main reasons for the overestimation of their body shape was comparison with others. Participants who were interested in a friend’s body shape were almost three times more likely to have a desire for thinness than those who were not interested in a female friend’s body shape (odds ratio: 3.06, P=0.014). Conclusion The results indicate a possibility that a female Japanese student’s young female friends’ body shapes, influences her desire for thinness or her perception of her own body shape.

  6. Semiclassical expansion of quantum characteristics for many-body potential scattering problem

    2007-01-01

    In quantum mechanics, systems can be described in phase space in terms of the Wigner function and the star-product operation. Quantum characteristics, which appear in the Heisenberg picture as the Weyl's symbols of operators of canonical coordinates and momenta, can be used to solve the evolution equations for symbols of other operators acting in the Hilbert space. To any fixed order in the Planck's constant, many-body potential scattering problem simplifies to a statistical-mechanical problem of computing an ensemble of quantum characteristics and their derivatives with respect to the initial canonical coordinates and momenta. The reduction to a system of ordinary differential equations pertains rigorously at any fixed order in ℎ. We present semiclassical expansion of quantum characteristics for many-body scattering problem and provide tools for calculation of average values of time-dependent physical observables and cross sections. The method of quantum characteristics admits the consistent incorporation of specific quantum effects, such as non-locality and coherence in propagation of particles, into the semiclassical transport models. We formulate the principle of stationary action for quantum Hamilton's equations and give quantum-mechanical extensions of the Liouville theorem on conservation of the phase-space volume and the Poincare theorem on conservation of 2p-forms. The lowest order quantum corrections to the Kepler periodic orbits are constructed. These corrections show the resonance behavior. (Abstract Copyright [2007], Wiley Periodicals, Inc.)

  7. From preferred to actual mate characteristics: the case of human body shape.

    Directory of Open Access Journals (Sweden)

    Alexandre Courtiol

    Full Text Available The way individuals pair to produce reproductive units is a major factor determining evolution. This process is complex because it is determined not only by individual mating preferences, but also by numerous other factors such as competition between mates. Consequently, preferred and actual characteristics of mates obtained should differ, but this has rarely been addressed. We simultaneously measured mating preferences for stature, body mass, and body mass index, and recorded corresponding actual partner's characteristics for 116 human couples from France. Results show that preferred and actual partner's characteristics differ for male judges, but not for females. In addition, while the correlation between all preferred and actual partner's characteristics appeared to be weak for female judges, it was strong for males: while men prefer women slimmer than their actual partner, those who prefer the slimmest women also have partners who are slimmer than average. This study therefore suggests that the influences of preferences on pair formation can be sex-specific. It also illustrates that this process can lead to unexpected results on the real influences of mating preferences: traits considered as highly influencing attractiveness do not necessarily have a strong influence on the actual pairing, the reverse being also possible.

    Full Text Available The aim of the present study was to evaluate the association of body image dissatisfaction with physical activity level and nutritional status in freshmen from a public Brazilian university. A total of 832 university students (485 men with a mean age of 20.1 years (standard deviation = 4.6 participated in the study. Self-reported body weight and height were used for the calculation of body mass index. The students responded to the Body Shape Questionnaire and International Physical Activity Questionnaire. Data were analyzed using Fisher’s exact test, considering p < .05. The prevalence of body image dissatisfaction and physical inactivity was 10.1% and 14.5%, respectively. No significant association was observed between body image dissatisfaction and physical activity level. Body image dissatisfaction was associated with nutritional status in both genders (p < .05. University students with excess body weight should be encouraged to pursue a healthier lifestyle in order to promote an adequate nutritional status and also to improve their body image.

    2016-01-01

    Medical students face rigorous and stressful work environments, resulting in high rates of psychological distress. However, there has been a dearth of empirical work aimed at modifying risk factors for psychopathology among this at-risk group. Distress tolerance, defined as the ability to withstand emotional distress, is one factor that may be important in promoting psychological well-being in medical students. Thus, the aim of the current mixed-methods study was (a) to describe changes in facets of distress tolerance (i.e., emotional tolerance, absorption, appraisal, regulation) for medical students who completed a mind-body skills training group, and a no-intervention control group of students; (b) to examine the relationship between changes in psychological variables and changes in distress tolerance; and (c) to report students' perceptions of the mind-body group, with an emphasis on how the group may have affected personal and professional functioning due to improvements in distress tolerance. The mind-body program was an 11-week, 2-hour skills training group that focused on introducing, practicing, and processing mind-body skills such as biofeedback, guided imagery, relaxation, several forms of meditation (e.g., mindfulness), breathing exercises, and autogenic training. Participants were 52 first- and second-year medical students (62.7% female, Mage = 23.45, SD = 1.51) who participated in a mind-body group or a no-intervention control group and completed self-report measures before and after the 11-week period. Students in the mind-body group showed a modest improvement in all distress tolerance subscales over time (ΔM = .42-.53, p = .01-.03, d = .44-.53), whereas the control group showed less consistent changes across most subscales (ΔM = .11-.42, p = .10-.65, d = .01-.42). Students in the mind-body group qualitatively reported an improved ability to tolerate affective distress. Overall, improvements in psychological symptoms were associated with

    The use of unclaimed bodies for anatomical dissection has been the main method of instruction at our institution. There is however a shortage of cadavers for dissection given the increase in the number of medical schools as well as in the number of students enrolling in these schools. This shortage could be mitigated by having voluntary human body donation programs. This study aimed at assessing the attitudes of medical students and surgical residents towards body donation for anatomy learning. We conducted an online survey involving 72 first-year medical students and 41 surgical residents at University of Nairobi who had completed one year of anatomy dissection. For the medical students, this was their first dissection experience while it was the second exposure for the surgery trainees. Most of the surgical trainees (70.7%) and medical students (68.1%) were opposed to self-body donation. This was mainly due to cultural (37%) and religious (20%) barriers. Surprisingly, of those not willing to donate themselves, 67.9% (82.8% surgical trainees, 59.2% medical students) would recommend the practice to other people. Exposure to repeated dissection does not change the perceptions towards body donation. It is noteworthy that culture and religion rank high as clear barriers amongst this “highly informed” group of potential donors. PMID:27190650

    We report on an investigation of student understanding of rigid body dynamics in which we asked students in introductory calculus-based physics to compare the translational motions of identical rigid bodies subject to forces that differed only in the point of contact at which they were applied. There was a widespread tendency to claim that forces that cause rotational motion have a diminished effect on translational motion. A series of related problems was developed to examine whether similar errors would be made in other contexts, and interviews were conducted to probe student thinking in greater depth. In this paper, we describe the results of our investigation and also describe a series of different interventions that culminated in the development of a tutorial that improves student ability to apply Newton's second law to rotating rigid bodies.

    The present study was designed to investigate orthorexia nervosa, or the phenomenon of being preoccupied with consuming healthy food. Specific aims were to explore relationships between orthorexia features and attitudes towards body image, fitness and health in normal weight female and male university students with high levels of healthy food preoccupation, i.e. orthorexia nervosa. Participants were 327 female (N = 283) and male (N = 44) students aged 18 to 25 years. All participants completed the Polish adaptation of the 15-item questionnaire assessing orthorexia eating behaviours (the ORTHO-15) and the Multidimensional Body-Self Relations Questionnaire (the MBSRQ). Relationships between scores on the ORTHO-15 and MBSRQ were explored in the 213 students who had high levels of preoccupation with a healthy food intake (68.55% women and 43.18% men, respectively). There were no statistically significant differences in the levels of orthorexia behaviours between females and males. In female students with orthorexia nervosa, preoccupation with consuming healthy food was significantly correlated with the MBSRQ subscale scores for overweight preoccupation, appearance orientation, fitness orientation, health orientation, body areas satisfaction and appearance evaluation. Conversely, in male students with orthorexia nervosa there were no correlations between orthorexic behaviours and the MBSRQ subscales. In female students with orthorexia nervosa multivariable linear regression analysis found high body areas (parts) satisfaction, low fitness orientation, low overweight preoccupation and low appearance orientation were independent predictors of greater fixation on eating healthy food. In male students, we found that aspects of body image were not associated with preoccupation with healthy eating. A strong preoccupation with healthy and proper food was not associated with an unhealthy body-self relationship among Polish female student with orthorexia nervosa.

    Parents take an important role in a child's development, but there is currently limited information on parental correlates with children's health behaviour. The purpose of this study, therefore, was to examine whether parental characteristics, such as body weight, TV consumption and sport participation, affect children's body weight and health behaviour. To examine the effects of parental characteristics on children's body weight and health behaviour, baseline data of 1,118 elementary school children (7.6 ± 0.4 years) participating in a school-based intervention in southwest Germany was used. Children's height and weight were measured and parent as well as child behaviour was assessed via questionnaire. BMI percentiles of children were positively associated with parental BMI (r = 0.2, p parental TV time increased the odds for high TV time in children (OR mother= 2.2, OR father = 2.3) and parental club sport participation increased the odds for club sport participation in children (OR mother = 1.9, OR father = 1.7). The relationship between parental and child behaviour was stronger than the relationship between parental BMI and BMI percentiles of the child. These results suggest that parental behaviour and role modeling provide an important contribution to childrens' health behaviour, especially at younger ages.

    This study investigated the temporal stability and correlates of attention-related body sensations that emerge without external stimulation during rest and due to focused attention on a body part. To assess attention-related body sensations, participants were asked to focus on a freely chosen body area with closed eyes, and had to report whether the sensation of that area had changed. Self-report questionnaires were used to assess various aspects of body focus (body awareness, body responsiveness, somatosensory amplification, subjective somatic symptoms), and positive and negative affectivity. Previous experiences in body-mind therapies were also measured. PEBL Continuous Performance Test was used to assess sustained attention. Heart rate variability scores were based on a 3-minute long resting heart rate measurement. Fifty-eight university students (22.3 ± 3.95 years; 34 females) participated in the study. The stability of attention-related body sensations was measured 8 weeks later on a randomly chosen sub-group (n = 28). Attention-related body sensations showed a mediocre temporal stability (r ρ  = 0.47, p = 0.012). People reporting attention-related body sensations showed significantly higher body awareness, somatosensory amplification, and resting heart rate; and marginally higher somatic symptoms. No relation was found with body-mind practice, body responsiveness, positive and negative affect, the vagal component of heart rate variability, and performance in the sustained attention task. Attention-related sensations are relatively stable over time. They are connected to some, but not to all of the aspects of body focus. Further studies are needed to elaborate the influencing stable and situational factors.

    2018-01-01

    Gifted students who also have learning disabilities (G/LD) are often overlooked when students are assessed either for giftedness or specific learning disabilities. The cognitive and non-cognitive characteristics of these G/LD students are habitually discussed only briefly alongside identification and intervention issues and, beyond that, the relevance of non-cognitive characteristics is often left unconsidered. Accordingly, this study aims to conduct an in-depth review of the non-cognitive characteristics of these students for identification and intervention purposes. Detailed analysis was performed on 23 publications. High levels of negative emotions, low self-perception, and adverse interpersonal relationships, as well as high levels of motivation, coping skills and perseverance were found among these students. A common characteristic was a high degree of frustration with the academic situation. The study reveals that these students show considerably duality in their non-cognitive characteristics which requires tailored counseling skills to provide effective support for their learning needs.

    Full Text Available The paper reveals the findings of a sociological research, conducted in January 2013 and aimed at defining the modern student’s socio-psychological profile. The survey involved 415 students aged from 17 to 22, studying at Moscow State Regional University, Russian State University of Tourism and Services, and the Financial and Technological Academy. The questionnaire, entitled to reveal the social facts, affecting students’ activity and behavior, as well as the conscious phenomena (motives, values, attitudes, etc., registered the students’ opinions on a wide range of both the social life and professional preference issues.The research presents the students’ socio-demographic characteristics, personal value orientations in different activity spheres, and cultural level; socialization problems and specifics of cooperation and interrelation with surrounding people being denoted along with participation in social and political life, and informal organizations.The main conclusion of the research emphasizes the fact of students’ exposure to the complicated socialization conditions. However, despite the adaptation problems, the author points out the growth of self-consciousness and intention to defend their opinions as the distinctive feature of that social group, the self-esteem being the primary behavior regulator.

    Educational processes and outcomes are influenced by a multitude of factors, including individual and contextual characteristics. Recently, studies have demonstrated that student and context characteristics may produce unique and cumulative effects on educational outcomes. The study aimed to investigate (1) the relative contribution of student, classroom, and school characteristics to reading fluency and orthographic spelling, (2) the relative contribution of specific predictors to reading fluency and orthographic spelling within the sets of student, classroom, and school characteristics, and (3) whether the contribution of student, classroom, and school characteristics differs for reading fluency and orthographic spelling. Participants were 789 German third-grade students from 56 classrooms in 34 schools. Students completed an intelligence test and a questionnaire assessing self-control. Reading fluency and orthographic spelling performance were assessed using standardized achievement tests. Multilevel structural equation modelling was used to control for the hierarchical structure of educational data. Variances in students' reading and spelling skills were in large part explained by student characteristics (>90%). Classroom and school characteristics yielded little variance. Student-level intelligence and self-control were significantly related to reading fluency. For orthographic spelling, student-level intelligence and self-control, class-average intelligence, and, at the school level, the socio-economic status of the school's neighbourhood were significant predictors. Future research needs to investigate relevant classroom and school factors that may directly and indirectly relate to academic outcomes. © 2015 The British Psychological Society.

Nipple and genital piercings (intimate piercings) have become common types of body art. Scant medical and nursing literature is available, leading to little understanding of these body modifications by health care providers. A convenience sample of intimately pierced individuals (63 women and 83 men) from 29 states in the United States of America was surveyed via an author-developed questionnaire. Questions focused on demographic characteristics, decision factors and health problems related to intimate piercings. Self-reported characteristics were compared between female and male participants, and participants were compared demographically to United States general population. Participants reported wearing nipple piercings (43%), genital piercings (25%) and both types (32%). Respondents were significantly younger, less ethnically diverse, better educated, less likely to be married, more often homosexual or bisexual and they initiated sexual activity at a younger age than the US population. Deliberate, individual decisions for procurement of the intimate piercings were made. Average purchase consideration was at age 25 (nipple) and 27 (genital); average age to obtain the piercing was 27 (nipple) and 28 (genital) years. Purposes for obtaining the piercings included uniqueness, self-expression and sexual expression. Most participants still liked their piercing (73-90%). Health concerns related to intimate piercings were described by both those with nipple piercings (66%) and with genital piercings (52%) and included site sensitivity, skin irritation, infection and change in urinary flow (male genital). Few STDs (3%) were reported and no HIV or hepatitis. Usually non-medical advice was sought for problems -- often from the body piercer. Understanding client rationale is not a necessary

    Full Text Available Abstract Background Body dysmorphic disorder (BDD is a psychiatric disorder characterized by a preoccupation with an imagined or slight defect which causes significant distress or impairment in functioning. Few studies have assessed gender differences in BDD in a non clinical population. Also no study assessed BDD in medical students. This study was designed to determine the point prevalence of BDD in Pakistani medical students and the gender differences in prevalence of BDD, body foci of concern and symptoms of BDD. Methods The medical students enrolled in a medical university in Karachi, Pakistan filled out a self-report questionnaire which assessed clinical features of BDD. BDD was diagnosed according to the DSM-IV criteria. Results Out of the 156 students, 57.1% were female. A total of 78.8% of the students reported dissatisfaction with some aspect of their appearance and 5.8% met the DSM-IV criteria for BDD. The male to female ratio for BDD was 1.7. Regarding gender differences in body foci of concern, the top three reported foci of concern in male students were head hair (34.3%, being fat (32.8%, skin (14.9% and nose(14.9%, whereas in females they were being fat (40.4%, skin (24.7% and teeth (18%. Females were significantly more concerned about being fat (p = 0.005. Male students were significantly more concerned about being thin (p = 0.01 and about head hair (p = 0.012. Conclusion BDD is fairly common in our medical student population, with a higher prevalence in males. Important gender differences in BDD symptomatology and reported body foci of concern were identified which reflected the influence of media on body image perception. The impact of cultural factors on the prevalence as well as gender differences in BDD symptomatology was also established.

    To study the effect of different human target's spectral reflective characteristic on low light level (LLL) image intensifier's distance, based on the spectral characteristics of the night-sky radiation and the spectral reflective coefficients of common clothes, we established a equation of human body target's spectral reflective distribution, and analyzed the spectral reflective characteristics of different human targets wearing the clothes of different color and different material, and from the actual detection equation of LLL image intensifier distance, discussed the detection capability of LLL image intensifier for different human target. The study shows that the effect of different human target's spectral reflective characteristic on LLL image intensifier distance is mainly reflected in the average reflectivity rho(-) and the initial contrast of the target and the background C0. Reflective coefficient and spectral reflection intensity of cotton clothes are higher than polyester clothes, and detection capability of LLL image intensifier is stronger for the human target wearing cotton clothes. Experimental results show that the LLL image intensifiers have longer visual ranges for targets who wear cotton clothes than targets who wear same color but polyester clothes, and have longer visual ranges for targets who wear light-colored clothes than targets who wear dark-colored clothes. And in the full moon illumination conditions, LLL image intensifiers are more sensitive to the clothes' material.

    Adolescents in the industrial world are becoming less physically active and are increasingly adopting a sedentary life-style in front of computers and television screens. to determine self-related health, physical activity, sleeping habits, prevalence of overweight, and body complaints in Australian senior high school students. Participants were 466 high school students aged 15-17 years enrolled in academic and vocational programs. A questionnaire was completed at two senior high schools with questions about weight and height, health, physical activity, type of physical activity/sport, intensity, sleeping habits, and possible injuries or complaints during the last three months. Seventy seven percent of the high school students participated in sports on a regular basis. Compared with vocational programs, more males and females in academic programs participated in sports (71% and 80% respectively) (p = .036). Males reported significantly better health than females (p sleep was reported in 82.1% of males and in 76.6% of females. In males, 44.3% were often sleepy in the daytime (females 56.6%, p sleep are factors with significant positive effect on good health, whereas overweight is a negative factor. Proper sleep habits and higher physical activity levels should be promoted among high school students, and TV viewing time and video game use restricted. Additionally, schools should provide opportunities for young people to participate in a wider range of physical activities that address their individual needs while promoting the health benefits of engaging in regular exercise.

    Most evidence-based body image programs for college students (e.g., the Body Project) are designed for female-only audiences, although body dissatisfaction is not limited to female-identified individuals. Furthermore, programs do not explicitly discuss diversity, although individuals with marginalized gender, racial, and sexual identities may be particularly vulnerable to body image disturbances. Making programs more inclusive may increase their disseminability. This qualitative study examined the feasibility of adapting the Body Project for universal and inclusive use with college students. Participants (N = 36; M age = 21.66 years; 73% female-identified; 20% sexual minority; 23% racial minority) attended one of five semi-structured focus groups to explore the inclusivity of appearance-based cultural norms using adapted Body Project activities and discuss the feasibility of universal and inclusive interventions. Inductive qualitative content analysis with three-rater consensus identified focus group themes. There was consensus that inclusive interventions could have a positive impact (broadening perspectives, normalizing body image concerns, increasing awareness) despite potential barriers (poor diversity representation, vulnerability). There was strong consensus regarding advice for facilitating inclusive interventions (e.g., skilled facilitation, education, increasing diversity). Results suggest that inclusive body image programs are desirable and provide a framework for creating the EVERYbody Project, a program for more universal audiences. © 2017 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Physical development can be considered as an indicator of the overall health status of the youth population. Currently, it appears that the increasing trend of the prevalence of obesity among children and youths has stopped in a number of countries worldwide. Studies point to the fact that adolescence is a critical period for the development of obesity. Body mass index (BMI seems to be an orientation parameter in the assessment of prevalence of obesity which is not sufficient for more accurate identification of at risk individuals. The purpose of this study was to evaluate association between BMI percentile zones as health-risk for being overweight and obese and body composition indicators in high-school students from the Prešov (Slovakia region. Methods A non-randomized cross-sectional study in high school students from the Prešov (Slovakia region was conducted. The research sample consisted of 1014 participants (boys n = 466, girls n = 549. Body composition was measured using direct segmental multi-frequency bioelectrical impedance analysis (DSM-BIA. To examine the association between obesity and selected body composition indicators, Kruskal-Wallis ANOVA and Eta2 were used. The relationship between selected body composition indicators and percentile BMI zones was determined using the Kendall tau correlation. Results In groups with different BMI percentile zones (normal weight, overweight, obese, ANOVA showed significant differences for girls and boys (p ˂.05 with high effect size (η2 ˂.26 in body weight, body fat mass index, body fat percentage, fat free mass index, fat-free mass percentage, visceral fat area, waist-to-hip ratio, waist circumference, protein mass and mineral mass. The highest degree of correlation among boys was between BMI values indicating overweight and obesity and fat free mass index and waist circumference, respectively (τ = .71, τ = .70, respectively. In girls, the highest

    Pathological eating attitudes and extreme weight control practices occur most commonly in certain female populations. In some young male occupation groups, such as in the armed forces, the appearance of physical strength and muscularity has particular importance. We studied body and eating attitudes and the prevalence of bodybuilding and steroid abuse in 480 military college and 752 general college male students. The Eating Disorder Inventory was used for all subjects. General college students had higher body mass index values than did military students. The prevalence of bodybuilding and steroid abuse was significantly greater in the military population. Comparisons between the study groups and within groups showed significantly different scores on certain Eating Disorder Inventory subscales. The study revealed that male military college students have some protective factors against the psychopathological features of eating disorders.

    Improvement in body condition and carcass traits through nutritional intervention was studied in cull ewes. Sixty-eight adult non-productive Malpura ewes (average body weight 26.7 ± 0.33 kg) were randomly divided into four equal groups: G0 maintained on free grazing for 8 h on protected natural rangeland with ad libitum guar (Cyamopsis tetragonoloba) straw (GS) after grazing; G1, G2 and G3 fed with supplemental concentrate at the rate of 250 g, 2.5% of live weight (LW) and ad libitum, respectively. The experiment was continued for 90 days and daily feed intake, weekly LW and body condition score (BCS) were recorded. Intake and digestibility of nutrients were assessed by indicator method. Rumen fermentation attributes and blood biochemical profile were studied to assess the dietary effects and animals were slaughtered at the end of experiment for evaluation of carcass characteristics. Higher dry matter (DM) intake and improvement in plane of nutrition was observed in G2 and G3 with a higher LW gain (LWG) and improvement in BCS than in G0. The digestibility of DM, organic matter, CP, ADF and cellulose was higher (P alimentation of cull ewes with challenged feeding of concentrate at 2.5% of LW on a basal roughage diet for a period of 3 months may have promise for better economic return to the farmers with possibly meeting quality mutton for human consumption.

    Objective To investigate the preoperative body composition, metabolic characteristics, and postoperative changes in patients with active acromegaly and analyze the effects of gender and age. Methods We included 36 patients with untreated acromegaly and 37 patients with nonfunctional pituitary adenomas. Adipose tissue (AT), the visceral fat index (VFI), sclerotin, protein, skeletal muscle, total body water (TBW), intracellular water (ICW), and extracellular water (ECW) were measured using bioelectrical impedance analysis (BIA). Total energy expenditure (TEE) and basal metabolism (BM) were measured with a cardiopulmonary and metabolic analyzer (CMA). Tricep skinfold thickness (TST), bicep circumference, waistline, hipline, and calf circumference were measured with a skinfold caliper and tape. These indices were measured before surgery and 3 months and 1 year after surgery. Results Overall, AT, VFI, and TST were lower, whereas sclerotin, protein, skeletal muscle, TBW, ICW, ECW, TEE, and BM were higher in acromegaly patients. Postoperatively, TST rose initially and then decreased, the waistline increased, and sclerotin, skeletal muscle, TEE, and BM decreased. Changes in these indices differed with gender and age in unique patterns. Conclusions Body composition and metabolism in acromegaly patients changed after surgery, and gender and age influenced these changes. PMID:29531529

    The last decade of research has suggested that family meals play an important role in promoting healthful dietary intake in youth. However, little is known about the structural characteristics and interpersonal dynamics of family meals that might help to inform why family meals are protective for youth. The current mixed methods, cross-sectional study conducted in 2010-2011 includes adolescents and parents who participated in two linked population-based studies. Participants included 40 parents (91.5% female) and adolescents (57.5% female) from the Minneapolis/St Paul, MN, area participating in EAT (Eating and Activity Among Teens) 2010 and F-EAT (Families and Eating and Activity Among Teens). The structural (eg, length of the meal, types of foods served) and interpersonal characteristics (eg, communication, emotion/affect management) of family meals were described, and associations between interpersonal dynamics at family meals and adolescent body mass index and dietary intake were examined via direct observational methods. Families were videorecorded during two mealtimes in their homes. Results indicated that family meals were approximately 20 minutes in length, included multiple family members, were typically served family style (70%), and occurred in the kitchen 62% of the time and 38% of the time in another room (eg, family room, office). In addition, significant associations were found between positive interpersonal dynamics (ie, communication, affect management, interpersonal involvement, overall family functioning) at family meals and lower adolescent body mass index and higher vegetable intake. These findings add to the growing body of literature on family meals by providing a better understanding of what is happening at family meals in order to inform obesity-prevention studies and recommendations for providers working with families of youth.

    Full Text Available Objectives & Methods: This suggestion was attempted to be elevated the recognition of common characteristics in disease. So, we performed to analyze the correlation of common cause of disease, characteristics of human body, and medical treatment. And the results are as follows. Results: 1. The cause of disease is consist of genetic factor, aging, habit, food of not good in health, weather, environment, deficit of the physical activity, stress and so on. 2. Generally, human has common and individual weakness. Individual weakness is appeared similar to the occurrence of volcano and lapse. 3. The correlation of disease and medical treatments is possible to explain using the quotation of the law of motion made by Isaac Newton, the great physicist. 4. When the process of the medical treatment was not progressed, the prognosis is determined by the correlation of the homeostasis(H' in human body and the homeostasis(H of disease. 5. The prognosis of disease is determined by the relationship between the energy of disease(F and medical treatment(F'. 6. The exact diagnosis is possible to predict the treatment sequence, and the facts that homeostasis in human body and disease, relationship between the energy of disease(F and medical treatment(F', action and reaction are important to determine the prognosis. 7. The careful observation of improving response and worsening action of disease becomes available for exact prognosis. Conclusion: The above described contents may be useful in clinical studies, and the concrete clinical reports about this will be made afterward.

    Full Text Available Background. The prevalence of body dysmorphic disorder (BDD among South African students is explored in this article. BDD is regarded as an obsessive-compulsive-related disorder characterised by a preoccupation with one or more perceived defects or flaws in physical appearance and expressed in repetitive behaviours or mental acts as a response to the appearance concerns, causing clinically significant distress or impairment in functioning.  Objectives. To determine the prevalence of BDD among undergraduate students (N=395 at an inner-city university.  Methods. Proportionate stratified random cluster sampling was used to select the sample. The students completed a demographics survey and the Body Image Disturbance Questionnaire.  Results and conclusion. An overall prevalence rate of 5.1% was found in this study, which is similar to prevalence rates reported in existing literature among student populations. No clinically significant differences in the severity of the BDD were found on the demographic variables of gender, race or sexual orientation. However, students differed significantly in their experience of the severity of the disorder in terms of age, in that students over the age of 21 reported higher severity levels than students under the age of 21. Although the prevalence of the disorder compares with that in other countries, its severity seems to increase with age among South African students.

    Although researchers in undergraduate science, technology, engineering, and mathematics education are currently using several methods to analyze learning gains from pre- and posttest data, the most commonly used approaches have significant shortcomings. Chief among these is the inability to distinguish whether differences in learning gains are due to the effect of an instructional intervention or to differences in student characteristics when students cannot be assigned to control and treatment groups at random. Using pre- and posttest scores from an introductory biology course, we illustrate how the methods currently in wide use can lead to erroneous conclusions, and how multiple linear regression offers an effective framework for distinguishing the impact of an instructional intervention from the impact of student characteristics on test score gains. In general, we recommend that researchers always use student-level regression models that control for possible differences in student ability and preparation to estimate the effect of any nonrandomized instructional intervention on student performance.

    2017-09-01

    The aim of the current study was to examine associations between body appreciation and putative correlates that focus on self-enhancement and self-expression. Students (N=261; mean age=20.16years, SD=3.68; 60.9% female) from a non-residential college in the northeastern United States completed a questionnaire measuring body appreciation, interest in cosmetic enhancements, and need for uniqueness. Individuals with higher body appreciation and African Americans/Blacks reported significantly higher self-attributed need for uniqueness and significantly higher investment in a distinctive appearance. The association between body appreciation and interest in cosmetic enhancements (e.g., hair coloring) was not significant. Results suggest that body appreciation may be linked to a desire to express one's own unique qualities. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Background: Mental disorders, including eating disorders, mostly begin during youth. Moreover, negative body image is found to cause unhealthy eating habits in the context of several cross-cultural settings. This study aimed to examine the correlation between health perception and body image with eating habits among high school students. Methods: A structured, anonymous questionnaire was distributed to students of a private high school in Bandung, Indonesia in June-October 2014. The questionnaire included questions about health perception, body image, eating habits, body weight and height, and also other demographic parameters. The school was selected as the study object through purposive sampling, and 140 high school students (72 male and 68 female were ramdomly selected. Results: Male and female did not show considerable differences in health perceptions. Out of 13 statements, 12 statements of male respondents showed better body image than female. While in eating habits statements, female respondents seemed to maintain healthier eating habits than male respondents. No significant correlation was observed between body image and eating habits (r=-0.015, p=0.858. There was significant correlation between health perception and eating habits (r=0.374, p<0.001. Correlation between sex and eating habits was found (p=0.020, there was not significant relationship between eating habits and Body Mass Index (BMI (p=0.368. Conclusions: The negative relationship between body image and eating habits is not significant. However there was a significant positive relationship between health perception and eating habits. Furthermore, there was correlation between sex and eating habits, while the positive relationship between eating habits and BMI was still not found.

    Full Text Available Abstract Background In our series of investigations concerning the causes of seasonal change in fat accumulation in young university students, we could not find any contribution of seasonal variation in the ratio of carbohydrate and fat metabolism to that of body fat percentage in Japanese and Thai participants. After our previous study, we examined the effect of daily physical activity on body fat percentage to look for the major causes of seasonal change in fat accumulation in young university students. Findings In this study, we measured participants’ (young Japanese and Thai university students daily physical activity by a uniaxial accelerometer in addition to the measurements of body fat percentage and body mass index by a bioelectrical impedance meter. We found that there was significant and moderate negative correlation between body fat percentage and daily step counts among Japanese but not Thai participants. We observed significant, moderate and positive correlations between the percentage of body fat and body mass index among Japanese and Thai participants. Conclusions Daily physical activity plays an important role in the seasonal variation of body fat percentage of Japanese female students. Our present study also confirmed the importance of daily physical activity for controlling body mass index and for the prevention of obesity.

    The purpose of this study was to determine how pelvic morphology, body posture, and standing balance variables of scoliotic girls differ from those of able-bodied girls, and to classify neuro-biomechanical variables in terms of a lower number of unobserved variables. Twenty-eight scoliotic and twenty-five non-scoliotic able-bodied girls participated in this study. 3D coordinates of ten anatomic body landmarks were used to describe pelvic morphology and trunk posture using a Flock of Birds system. Standing balance was measured using a force plate to identify the center of pressure (COP), and its anteroposterior (AP) and mediolateral (ML) displacements. A multivariate analysis of variance (MANOVA) was performed to determine differences between the two groups. A factor analysis was used to identify factors that best describe both groups. Statistical differences were identified between the groups for each of the parameter types. While spatial orientation of the pelvis was similar in both groups, five of the eight trunk postural variables of the scoliotic group were significantly different that the able-bodied group. Also, five out of the seven standing balance variables were higher in the scoliotic girls. Approximately 60% of the variation is supported by 4 factors that can be associated with a set of variables; standing balance variables (factor 1), body posture variables (factor 2), and pelvic morphology variables (factors 3 and 4). Pelvic distortion, body posture asymmetry, and standing imbalance are more pronounced in scoliotic girls, when compared to able-bodied girls. These findings may be beneficial when addressing balance and ankle proprioception exercises for the scoliotic population.

    2010-10-01

    In December 2006 blooms of Oscillatoria rubescens were found in the reservoir Prizzi in Sicily. Oscillatoria is a genus of filamentous alga comprising approximately 6 species, between these the O. rubescens is sadly famous since this organism produces microcystins which are powerful hepatotoxins. Firstly found in Europe in 1825 on Geneva lake, recently (2006) those algae has been find out in Pozzillo, Nicoletti e Ancipa reservoirs (Enna Province), as well as in Prizzi (Palermo Province) and Garcia reservoirs (Trapani Province). Toxins produced by those bacteria (usually called microcystine LR-1 and LR-2) are highly toxic since they can activate oncogenes cells causing cancer pathologies on liver and gastrointestinal tract. Even if water treatment plants should ensure the provision of safe drinking water from surface waters contaminated with those toxic algae blooms, the contamination of reservoirs used for civil and agricultural supply highlights human health risks. International literature suggests a threshold value of 0.01 μgl-1 to avoid liver cancer using water coming from contaminated water bodies for a long period. Since O. rubescens activities is strongly related to phosphate and nitrogen compounds as well as to temperature and light transmission within water, the paper presents the comparison between optical properties of the water of an infested reservoir and those of a reservoir characterized by clear water. Field campaigns were carried out in February-March 2008 in order to quantify the spectral transparencies of two water bodies through the calculation of the diffuse attenuation coefficient, measuring underwater downwelling irradiance at different depths as well as water spectral reflectance. Results show that diffuse attenuation coefficient is reduced by approximately 15% reducing light penetration in the water column; coherently reflectance spectral signature generally decreases, exhibiting a characteristic peak around 703 nm not present in

  19. The transmission of vertical vibration through seats: Influence of the characteristics of the human body

    2011-12-01

    The transmission of vibration through a seat depends on the impedance of the seat and the apparent mass of the seat occupant. This study was designed to determine how factors affecting the apparent mass of the body (age, gender, physical characteristics, backrest contact, and magnitude of vibration) affect seat transmissibility. The transmission of vertical vibration through a car seat was measured with 80 adults (41 males and 39 females aged 18-65) at frequencies between 0.6 and 20 Hz with two backrest conditions (no backrest and backrest), and with three magnitudes of random vibration (0.5, 1.0, and 1.5 m s -2 rms). Linear regression models were used to study the effects of subject physical characteristics (age, gender, and anthropometry) and features of their apparent mass (resonance frequency, apparent mass at resonance and at 12 Hz) on the measured seat transmissibility. The strongest predictor of both the frequency of the principal resonance in seat transmissibility and the seat transmissibility at resonance was subject age, with other factors having only marginal effects. The transmissibility of the seat at 12 Hz depended on subject age, body mass index, and gender. Although subject weight was strongly associated with apparent mass, weight was not strongly associated with seat transmissibility. The resonance frequency of the seat decreased with increases in the magnitude of the vibration excitation and increased when subjects made contact with the backrest. Inter-subject variability in the resonance frequency and transmissibility at resonance was less with greater vibration excitation, but was largely unaffected by backrest contact. A lumped parameter seat-person model showed that changes in seat transmissibility with age can be predicted from changes in apparent mass with age, and that the dynamic stiffness of the seat appeared to increase with increased loading so as to compensate for increases in subject apparent mass associated with increased sitting

    Particular strategies of media advocacy can help people contest the dominant body images of fashion advertisements and reframe them to include a broader array of "normal" images. A study with an intervention group (n = 60) and a comparison group (n = 45) of undergraduate college students was conducted to investigate whether analyzing and reframing fashion advertisements changed the students' attitudes and behaviors regarding their own body images. Results from the posttest showed a significant change in beliefs among those in the intervention group but no significant change in behaviors. The comparison group showed no significant change in beliefs or behaviors. Posttest results from the women in the intervention group (n = 44) indicated a significant change in the study participants' beliefs that adult models in advertisements have an ideal body size and shape and that the participants' decisions about dieting or exercising should be based more on looks rather than on health status.

    2011-04-01

    In the face of the rising number of doctoral recipients in professional psychology, many have voiced concerns about the quality of nontraditional training programs. Past research suggests that, on a variety of outcomes, graduates from clinical PhD programs outperform graduates from clinical PsyD and, to a lesser extent, counseling PhD programs. We examine an aggregate archival dataset to determine whether student or university characteristics account for the differences in outcomes among programs. The data show meaningful differences in the outcomes of clinical PhD, PsyD, and counseling PhD programs. Furthermore, graduates from research-intensive universities perform better on the psychology licensure exam and are more likely to become American Board of Professional Psychology diplomates. The available data support the notion that the ability to conduct research is an essential component of graduate education. In this light, PsyD programs represent a unique opportunity to train students in the types of evaluation and outcomes assessments used by practicing psychologists. We discuss implications for graduate-level training in professional psychology. © 2011 Wiley Periodicals, Inc.

This scale was evaluated among male and female Malaysian university students. A total of 671 university students (52.2% women and 47.8% men) completed a self-administered questionnaire on MBIS, Eating Attitude Test-26, and Rosenberg Self-Esteem Scale. Their height and weight were measured. Results in confirmatory factor analysis showed that the 62-item MBIS reported poor fit to the data, xhi2/df = 4.126, p self-esteem. Also, this scale discriminated well between participants with and without disordered eating. The MBIS-46 demonstrated good reliability and validity for the evaluation of body image among university students. Further studies need to be conducted to confirm the validation results of the 46-item MBIS.

    Objective Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, is an often-severe, understudied disorder. We determined BDD’s prevalence and clinical features on a general adult psychiatric inpatient unit. To our knowledge, only one previous prevalence study has been done in this setting. Method One hundred patients completed 3 self-report measures: the Body Dysmorphic Disorder Questionnaire (BDD-Q), Beck Anxiety Inventory (BAI) and Center for Epidemiologic Studies Depression Scale (CES-D). Those who screened positive for BDD were interviewed to confirm DSM-IV BDD and its clinical features. Charts were reviewed for demographic and clinical information. Results BDD was diagnosed in 16.0% (95% CI=8.7–23.3%) (n=16) of patients. A high proportion of those with BDD reported that BDD symptoms contributed to suicidality. Patients revealed BDD symptoms to a mean of only 15.1%±33.7% lifetime mental health clinicians; only one (6.3%) reported symptoms to his current inpatient psychiatrist. Most did not disclose their symptoms due to embarrassment. Those with BDD were younger (P=.008) and had higher CES-D scores (P=.008). The two groups did not significantly differ on BAI score, demographic characteristics or discharge diagnoses. Conclusions BDD is relatively common but underdiagnosed in psychiatric inpatients and is associated with more severe depressive symptoms. PMID:18164943

    2014-01-01

    Full Text Available A group of dogs known as hounds is widespread and highly appreciated among the hunters on the Balkans. Hounds are referred to as hunting dogs that engage in loud pursuit of game along its trail. These dogs do not need to se the game in order to pursue it and begin to bark once they stumble upon game trail. First serious research along with zootechnical measurement was conducted in 1905, at which occasion three large groups of hounds that inhabit the Balkans were described. This undertaking provided a solid foundation for further research and standardization of certain hound breeds. Though a lot of field work and standardization efforts were undertaken since then, there are still groups of hounds not encompassed in previous research work that are well-spread on the field and frequently utilized as hunting companions. One of the variety among these non-standardized breeds are Bulgarian scent hound, which differ from described hound breeds by certain exterior characteristics. In this paper, processed and analyzed some of the basic exterior features of body and head of the Bulgarian Scent Hound. Measurements were performed in 21 males and 15 females of following parameters, the height at withers, back height, loin height, chest circumference, body length, head length, skull length, nozzle length, head width and nozzle width. The average height of males is 54.60 and female 51.73 cm. Head length of males, on average, was 23.95 cm and females 23, 53 cm.

    Background: The recent and rapidly popularized social phenomenon of selfie taking has been showing an increasing trend. It is thus imperative to assess the knowledge, attitude, and perception of the groups toward this phenomenon. Selfie taking is associated with younger age groups and hence, we aimed to explore the attitudes toward selfie taking and its relation toward body image and narcissism in medical college students. Methodology: This was cross-sectional study and had two groups with Group A comprising 92 first year medical students and Group B including 103 postgraduate (PG) medical students from various specialties. They were interviewed in a single session using the scale of attitude toward selfie-taking questionnaire, Body Image Acceptance and Action Questionnaire (BIAAQ), and the narcissistic personality inventory. Scores obtained were computed using basic descriptive statistics and t-test where appropriate. Results: A strong positive favorable trend toward selfie taking was noticed among both groups (A = 56.5%, B = 45.6%). There was no difference in attitude between the two groups, or difference in the gender between those clicking their own selfies regularly within each group. BIAAQ reflected a significant difference among male subjects of the two groups with PG students was more concerned about body image (P = 0.001), whereas female subjects of both groups showed no such difference. The narcissism traits also showed a significant difference, only when males of both groups were compared again in favor of PG medical students (P = 0.022). Conclusion: This study revealed that selfie-taking is popular among medical students both in their undergraduate and PG period. Further research in diverse clinical and nonclinical populations is warranted to explore the relation between this phenomenon and body image acceptance or narcissistic traits. PMID:29403124

  8. Who perceives they are smarter? Exploring the influence of student characteristics on student academic self-concept in physiology.

    Academic self-concept is one's perception of his or her ability in an academic domain and is formed by comparing oneself to other students. As college biology classrooms transition from lecturing to active learning, students interact more with each other and are likely comparing themselves more to other students in the class. Student characteristics can impact students' academic self-concept; however, this has been unexplored in the context of undergraduate biology. In this study, we explored whether student characteristics can affect academic self-concept in the context of an active learning college physiology course. Using a survey, students self-reported how smart they perceived themselves to be in the context of physiology relative to the whole class and relative to their groupmate, the student with whom they worked most closely in class. Using linear regression, we found that men and native English speakers had significantly higher academic self-concept relative to the whole class compared with women and nonnative English speakers. Using logistic regression, we found that men had significantly higher academic self-concept relative to their groupmate compared with women. Using constant comparison methods, we identified nine factors that students reported influenced how they determined whether they were more or less smart than their groupmate. Finally, we found that students were more likely to report participating more than their groupmate if they had a higher academic self-concept. These findings suggest that student characteristics can influence students' academic self-concept, which in turn may influence their participation in small-group discussion and their academic achievement in active learning classes.

    The objective of this study was to evaluate the association between the percep­tion of body image and the stages of behavioral changes related to physical activity among Physical Education Students. Two hundred thirty six students were included. We measured the perception of body image (silhouettes scale, the stages of changes in behavior related to physical activity using a questionnaire developed by Marcus et al., and socio-demographic variables (gender, age, parental education, marital status, course, employment situation, housing, period of study and income. We used descriptive analysis, chi-square test, Fischer’s exact test, crude and adjusted multinomial regression to estimate the odds ratio (OR and 95% confidence intervals (95% CI. The prevalence of physically inactive behavior was 18.2% for males and 23.9% for females. Dissatisfaction with body image was associated with the stages of behavioral changes in females, with women with physically inactive behavior having greater odds of experiencing dissatisfaction with their body image, both for underweight (OR: 9.69; 95% CI: 1.05-89.30 and overweight (OR: 5.49; 95% CI: 1.07-28.11 when compared with women who were satisfied with their body image. We suggest the development of in­terventions aimed at the adoption of regular physical activity in order to promote greater satisfaction with body image.

    College students continue to report being disrupted by other students' alcohol use. This study was designed to develop measures to document the consequences resulting from other students' drinking and identify differences in experiencing these consequences by student characteristics and drinking behaviors. A stratified random sample of undergraduate students (N = 3,908) from ten universities in North Carolina, USA, completed a web-based assessment. Exploratory factor analysis (EFA) was performed on the random first split-half sample (n = 1,954) to identify factor structure. Confirmatory factor analysis (CFA) was performed on the remaining half sample (n = 1,954) using structural equation modeling. EFA revealed two inventories: interpersonal and community consequences of others' drinking inventories. CFA on the second split-half sample identified model fits for the two factor structure suggested by EFA. Of 3,908 participants, 78% reported experiencing one or more consequences due to others' drinking during the past 30 days. Multivariable generalized linear mixed modeling further validated the inventories and resulted in several associations. Male students who reported getting drunk experienced significantly more interpersonal consequences from others' drinking (p students, students who lived on campus and students who reported getting drunk experienced significantly more community consequences from others' drinking (p college students experience consequences from others' drinking, and consequences vary for different subgroups of students. Although these inventories should be tested further, these findings propose standardized measures that may be useful to assess the consequences of others' drinking among college students.

    The social construction of knowledge within medical education is essential for learning. Students' interactions within groups and associated learning artifacts can meaningfully impact learning. Situated cognition theory poses that knowledge, thinking, and learning are located in experience. In recent years, there has been a reported decline in time spent on anatomy by whole body dissection (AWBD) within medical programs. However, teaching by surgeons in AWBD provides unique opportunities for students, promoting a deeper engagement in learning. In this study, we apply situated cognition theory as a conceptual framework to explore students' perceptions of their learning experience within the 2014 iteration of an 8-week elective AWBD course. At the end of the course, all students (n=24) were invited to attend one of three focus groups. Framework analysis was used to code and categorize data into themes. In total, 20/24 (83%) students participated in focus groups. Utilizing situated cognition theory as a conceptual framework, we illustrate students' learning experiences within the AWBD course. Students highlighted opportunities to create and reinforce their own knowledge through active participation in authentic dissection tasks; guidance and clinical context provided by surgeons as supervisors; and the provision of an inclusive learning community. Situated cognition theory offers a valuable lens through which to view students' learning experience in the anatomy dissection course. By doing so, the importance of providing clinical relevance to medical teaching is highlighted. Additionally, the value of having surgeons teach AWBD and the experience they share is illustrated. The team learning course design, with varying teaching methods and frequent assessments, prompting student-student and student-teacher interaction, was also beneficial for student learning.

    Participation in sports has important implications, being associated with health and social features. The objectives of this study were to verify whether there were any differences in sport participation between immigrant and Italian children and whether there was any relation with their body composition and fitness characteristics. A survey was conducted on 1432 children attending primary school in the Emilia-Romagna (northern Italy). Anthropometric measurements, fitness characteristics, and data about participation in sports were considered. Italian children were more likely to participate in sports than immigrants and boys than girls. Among immigrants, the lowest values were observed in Asians. Eastern European males and Latin American females displayed the widest dimensions. Eastern Europeans generally showed the highest values of strength, while Latin Americans had the highest values of flexibility. Asian children showed the highest values of centripetal fat, and a high percentage of them exceeded the %F reference. These aspects, together with the low frequency of practicing sports, place Asians at greater risks for health. Sex and ethnic group are the most informative variables associated with participation in sports by children. Interventions including health education lessons and promoting the participation in sports for immigrant children attending schools need to be encouraged. © 2017 John Wiley & Sons A/S.

    Full Text Available To reach the effectiveness of study, it is recommended to work on active learning method. The learning activity must be done with emphasis on the students’ characteristics. The characteristic means internal factors (cognitive entry behavior and affective entry characteristics, which are considered important as solving problems. The previous studies have shown that there is a correlation between achievement test and students’ characteristic entry behavior. At the beginning of the academic year of 2003, Faculty of Dentistry, University of Indonesia started active learning with PBL curriculum for the BDS degree. From a study about the correlation between the achievement and students’ entry behavior (previous knowledge, self concept, attitude, and anxiety during attending the test the study showed that characteristic entry behavior contributes to the student’s achievement test. The results supported the previous study.

    Full Text Available ABSTRACT Objective Social anxiety disorder (SAD and body image dissatisfaction (BID are common problems among college students, but few studies focused on medical students. We aimed to estimate the prevalence, severity and correlates of SAD symptoms and BID among medical students of a Brazilian public university. Methods A cross-sectional study with 479 students, using structured instruments: Social Phobia Inventory (SPIN, Body Shape Questionnaire (BSQ, and Beck Depression Inventory (BDI. Bivariate analyses were followed by logistic regression models to obtain independent predictors of SAD symptoms, BID and both outcomes combined. Results Most students were single (99% and female (58.7%. The prevalence rates of SAD symptoms (SPIN ≥ 19 and BID (BSQ ≥ 81 were 36.3% and 34.7%, respectively. Depressive symptoms (BDI ≥ 19 occurred in 8.8% of the sample. SAD symptoms were independently associated with: BID, thoughts of abandoning the course, difficulty making friends, depressive symptoms, and mental health treatment prior to university. Besides SAD symptoms, BID was associated with female sex, difficulty making friends, depressive symptoms, and body mass index (BMI. Seventy-eight students (16.3% presented SAD symptoms and BID, which was associated with female sex, difficulty making friends, dissatisfaction with the course, depressive symptoms and BMI. Conclusion SAD symptoms and BID are common and related problems that should be screened for among medical students. The identification of specific correlates could contribute to the elaboration of preventive measures, minimizing the distress and negative impact of these mental health problems on relationships and academic performance.

    Thirty-seven samples of ancient Chinese Ru porcelain bodies unearthed from Qingliangsi kiln (containing 32 Ru official porcelain bodies and 5 Ru folk porcelain bodies), thirty-two samples of ancient celadon bodies from Zhanggongxiang kiln, and fourteen samples of modern mineral, were selected and analyzed by neutron activation analysis (NAA) method. Twenty-three elements were measured. The data of these elemental contents were processed by scatter analysis and principle component analysis methods in order to determine the characteristics and sources of the raw materials of the celadon porcelain bodies from the foregoing two kilns. The results show that Fe, Ce, Ba, Ta, Th, La, Sm and Cr are the fingerprint elements to distinguish the ancient Ru official porcelain bodies from ancient celadon bodies of Zhanggongxiang kiln. The sources of the raw material of the ancient Ru official porcelain bodies from Qingliangsi kiln are more concentrated and stable than those from Zhanggongxiang kiln. The Ru folk porcelain bodies and the Ru official porcelain bodies from Qingliangsi kiln have the same provenance, both sources of which are local. The raw material origins of the ancient celadon bodies from Zhanggongxiang kiln is a little dispersed and the compositions of the raw material are different from the Ru porcelains, but the distance is not far away from each other.

    Full Text Available Background: Body image dissatisfaction and eating disorders are of common problems in adolescence and adulthood especially among athletes. Objective: The aim of this study was to determine the association of eating disorders and body image in athletes and non-athlete students in Qazvin University of Medical Sciences. Methods: This cross-sectional study was conducted on 226 athlete students and 350 non-athlete students of Qazvin University of Medical Sciences during 2013-2014. Students who followed a specific sport field and had participated in at least one sport event were considered as athlete students. All athlete students were entered the study by census method. Non-athlete students were selected among students who had not any exercise activity and by random sampling method. Data were collected through demographic questionnaire, Eating Attitudes Test (EAT-26, and Multidimensional Body-Self Relations Questionnaire (MBSRQ. Data were analyzed using T-test and Chi-square test. Results: Mean age was 21.92±3.19 years and mean body mass index (BMI was 22.24±3.18 kg/m2. The frequency of eating disorders was 11.5% among the athlete students and 11.2% among the non-athlete students. Anorexia nervosa was found to be more prevalent than bulimia nervosa in both groups. The students with normal BMI had better body image perception and less eating disorders symptoms than other students. The association of age, educational level, and gender with eating disorders and body image was not statistically significant. The association of eating disorders and body image was not statistically significant. Eating disorders were more prevalent in males than females but the difference was not statistically significant. Conclusion: With regards to the results, it seems that eating disorders and body image dissatisfaction are relatively prevalent among both athletes and non-athlete students and BMI is predictor of eating disorders.

    Health workers and medical students are at occupational risk of blood-borne diseases during the accidents, that is, via percutaneous injury or entry of blood or body fluids through the mucosa or injured skin. to review and analyze the knowledge, attitudes and perception of risks of bloodborne diseases of the clinical course students and health workers as well as the frequency of accidents. Cross-sectional study was carried out among the students of the Faculty of Medicine in Belgrade, and health workers of the Clinical Center of Serbia. The subjects responded anonymously to questionnaire specially designed for the study. Both students and health workers were aware, in a high percentage, of the fact that the risk of hepatitis B spread was about 30%. Significantly more students gave affirmative reply that blood as biological material was a potential hazard of HIV infection spread (p = 0.001), and significantly more students knew that HIV would not be spread by sweat (p = 0.001). Hepatitis B vacci-nation was administered only to 24.1% of students and 71.4% of health workers. About 10% of students and 65.5% of health workers experienced some accident. There was no significant difference of accidents bet-ween nurses/technicians and physicians (p > 0.05), as well as of accidents and a total length of service (p > 0.05). The majority of accidents occurred during the use of needle/sharp object (in 27.3% of students and 33.1% of health workers). About 40% of students and slightly over a half of the workers reported the accidents to appropriate authorities. Additional education in this field is considered necessary by 73% of students. During the studies and via continuous medical education it is necessary to upgrade the level of knowledge on prevention of accidents, what would, at least partially, influence their reduction.

    To determine the prevalence of and factors associated with body image dissatisfaction among physical education students enrolled in a public university. This study evaluated 236 students and assessed body image perception (silhouette scale), sociodemographic variables (sex, age, parental education, marital status, university course, work, living arrangement, study shift, and income), physical activity level (International Physical Activity Questionnaire - Short Version), dietary habits, tobacco use, excessive intake of alcohol (questions from the tobacco, alcohol and drugs, and nutrition domains of the FANTASTIC instrument), and nutritional status (body mass index [BMI]). Descriptive analysis, the chi-square test, Fisher's exact test, and crude and adjusted multinomial regression were used. The prevalence of body image dissatisfaction was 69.5%; 44.1% were dissatisfied with excess weight. BMI ≥ 25.0 kg/m² was associated with dissatisfaction with excess weight; factors associated with dissatisfaction with slimness were being male, eating an unhealthy diet, and smoking tobacco. Our findings suggest that female college students with a BMI ≥ 25.0 kg/m² are more likely to present dissatisfaction with excess weight. Being male, eating an unhealthy diet, engaging in physical activity for smoking tobacco were the variables associated with dissatisfaction with thinness.

    To identify the prevalence of body image dissatisfaction and associated factors among students in Salvador, Brazil. A cross-sectional study involving a random sample of 1,494 (852 girls and 642 boys) adolescents between 11 and 17 years of age who were students in the public schools in Salvador, Brazil. Participants completed the Body Shape Questionnaire and the Eating Attitudes Test-26. Body image was characterized as satisfactory or unsatisfactory. We obtained demographic, anthropometric and economic information and information regarding the stage of maturation, self-perception of body weight, and consumption of sweetened beverages and diet soft drinks. To identify associated factors we used Poisson regression analysis. Body image dissatisfaction was present in 19.5% of the adolescents, with a prevalence of 26.6% among the girls and 10% among the boys. Independent of sex, the prevalence of body image dissatisfaction was higher among adolescents who were overweight or obese (girls, PR: 1.38, CI: 1.09-1.73 and boys, PR: 2.26, CI: 1.08-4.75), higher among those who perceived themselves as fat (girls, PR: 2.85, CI: 2.07-3.93 and boys, PR: 3.17, CI: 1.39-7.23), and higher among those who had negative attitudes toward eating (girls, PR: 2.42, CI: 1.91-3.08 and boys, PR: 4.67, CI: 2.85-7.63).. A reduction in body image dissatisfaction was only identified among underweight girls (PR: 0.12, CI: 0.03-0.49). A high occurrence of body image dissatisfaction was observed among the adolescents, and biological and behavioral factors were associated with this dissatisfaction.

    Presently, the internet plays a big role in daily life, especially for adolescents. In this age group, they are more concerned about their face and body shape. Despite the numerous studies on the effect traditional media has on body image, very few have focused on the effect of newer forms of media (e.g. online media). And almost none have looked at the relationship between time spent online and body image. To study the associations between time spent on the internet, body image satisfaction and eating behaviors of students grades 7 to 12 in the Thai educational system. The sample group included 620 students, who were selected using simple random sampling from 6 secondary schools in Bangkok. Data were collected using the Media and Internet use behavior questionnaires, The Body-Esteem Scale for Adolescents and Adults: Thai version (BESAA), Drive for Muscularity Scale (DMS: males only), The Rosenberg Self-Esteem Scale: Thai version, Eating Attitude Test-26: Thai version (EAT-26) and the eating behaviors at risk of obesity questionnaire. Mean (sd) age of the sample was 15.7 (1.9) years, 246 participants (39.7%) were male and 374 (60.3%) were female. Using the internet and social networks for content related to body image and eating behaviors, was negatively associated with body image satisfaction but positively associated with inappropriate eating attitudes/behaviors, binging, purging, use of laxatives/diuretics and drive for muscularity with respect to behaviors and attitudes, and was associated with eating behaviors that carried a risk for obesity. Time spent on internet, especially engaged in activities related to self-image, and eating attitudes and behaviors, were associated with a decrease in body image satisfaction and problematic eating behaviors.

    Abnormal eating behavior, unhealthy weight control methods, and eating disordered symptoms have risen among college students. The aim of this study was to examine disordered eating attitudes and their relationship with anthropometric and body composition indices in physical education students in Tabriz, the capital of East Azerbaijan province, Iran. This cross-sectional study was conducted on 210 physical education students, 105 males and 105 females aged 18 to 25, who were selected by systematic random sampling from physical education faculty of Tabriz University in Tabriz, Iran, in 2013. Eating attitude test (EAT-26) was used for the assessment of disordered eating attitudes. In addition, anthropometric and body composition indices were assessed. About 10% of the studied subject had disturbed eating attitudes; significantly more males (15.4%) reported an EAT-26 ≥ 20 (disordered eating attitudes) than females (4.8%) (P EAT-26 score was positively correlated with weist perimeter (WP) (r = 0.21, P EAT-26 score was positively correlated with weight (r = 0.19, P eating attitude and healthy subjects, while in males there was no significant difference between the two groups regarding the anthropometric and body composition indices. Abnormal eating attitude was notable among physical education students in Tabriz, Iran. It seems that some anthropometric indices such as BMI and central obesity indices were related to the increase of disordered eating attitude.

    Abstract Background: Little is known about which diversity characteristics if any, impact on nursing students' clinical placements or how these may affect the quality of their learning experiences. There is therefore a need to better understand these effects not only from the student's perspective but also from the perspective of the staff who supervise them, in order to ensure students obtain maximal benefit from their placements. To describe the clinical experiences of nursing students and the diversity characteristics that affect this learning experience. Data were collected from a series of open-ended questions embedded within a larger anonymous web-based survey, from August 2011 to March 2012. Participants included first, second and third year undergraduate Bachelor of Nursing students (N = 704) and faculty members involved in the clinical learning environment (N = 165) from seven Australian universities. Qualitative findings were clustered into three main themes: differences, difficulty and discrimination, each with three sub-themes. FINDINGS suggest a need to offer appropriate support for nursing students who feel different because of diversity characteristics. Whilst some of the participant perceptions are confronting they provide valuable insights for universities developing curricula and the clinical placement facilities where students obtain their experience.

    Full Text Available Abstract Background With the rapid increase in obesity rates, determining critical periods for weight gain and the effects of changes in fat mass is imperative. The purpose of this study was to examine changes in body weight and composition over the holiday season (Thanksgiving through New Year's in male and female college students. Methods Subjects completed three visits: the first occurred within 2 weeks prior to Thanksgiving, the second occurred within 5 to 7 days following Thanksgiving, and the third occurred within 10 days following New Year's Day. A total of 82 healthy male and female college age subjects participated. Body composition by dual energy x-ray absorptiometry (DXA was assessed at visits 1 and 3 while body weight was assessed at all three visits. Results Average body weight remained relatively unchanged from pre-Thanksgiving to post-New Year's (71.3 ± 14 kg vs. 71.2 ± 15 kg; P = 0.71 and, in fact, a subset of normal weight subjects lost a significant amount of body weight. However, percent body fat (25.9 ± 9 %fat vs. 27.0 ± 9 %fat; P P P = 0.08 was not significantly different than the post-New Year's. A significant positive relationship (P P Conclusion Despite the fact that body weight remained unchanged over the course of the holiday season, a significant increase in %body fat and fat mass was observed. With recent evidence showing marked morbidity and mortality to be associated with increased body fat (particularly abdominal adiposity, results from this study suggest body weight alone may underestimate the potentially deleterious effects of the holiday season.

    To determine the validity and reliability of the 13-figure images scale (13-CS) and Standard Figural Stimuli (SFS) for the evaluation of body images in adolescent students from Bucaramanga. A probabilistic sample with 189 students was evaluated with the two scales. Two weeks later, the valuation together with the size, weight, percentage of body fat, SCOFF questionnaire and Rosenberg self-esteem valuation was repeated. The average age was 14.1 years; 62.7% were women. The correlation of the 13-CS and SFS with body fat index, weight and body fat percentage was 0.61, 0.74, 0.40 and 0.72, 0.55, 0.45 respectively. The correlation of dissatisfaction with body image according to the SCOFF and the Rosenberg scales was 0.43 and 0.26 with the 13-CS; 0.50 and -0.23 with the SFS. The reproducibility shows that perceived and ideal figure was 0.93 and 0.90 with the 13-CS; and 0.85 and 0.78 with the SFS. the concurrent validity of both scales was good. The reproducibility of the 13-CS was excellent while the SFS was good. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

    The aim of this study was to find out the association of media and obesity status with body weight concern among female university students in Kuwait. 228 female students, aged 19-25 years, were selected at convenience from the Women's College in Kuwait. A previously validated questionnaire was used to collect information on the role of media in body concern and how parents, peers and the girls themselves perceived girls' body shapes. Weight and height were gathered by self-reporting. Use of internet and reading women's magazines had a significant impact on dieting by the girls to lose weight (Pobese girls than non-obese girls. Only watching television had a significant impact on girls' body shape concern (Pobese and 81% of obese girls were dissatisfied with their current weight. There were significant differences between obese and non-obese girls regarding the girls' views and the views of their peers and parents about the body weight of the girls (P<0.000 for all). The pressure from peers and parents, in addition to the mass media, may lead to disturbed attitudes towards eating among Kuwaiti girls. Copyright © 2012 Elsevier Ltd. All rights reserved.

    This study sought to identify the principal components of self-esteem and the health behavioural determinants of these components among grade five students. We analysed data from a population-based survey among 4918 grade five students, who are primarily 10 and 11 years of age, and their parents in the Canadian province of Nova Scotia. The survey comprised the Harvard Youth and Adolescent Questionnaire, parental reporting of students' physical activity (PA) and time spent watching television or using computer/video games. Students heights and weights were objectively measured. We applied principal component analysis (PCA) to derive the components of self-esteem, and multilevel, multivariable logistic regression to quantify associations of diet quality, PA, sedentary behaviour and body weight with these components of self-esteem. PCA identified four components for self-esteem: self-perception, externalizing problems, internalizing problems, social-perception. Influences of health behaviours and body weight on self-esteem varied across the components. Better diet quality was associated with higher self-perception and fewer externalizing problems. Less PA and more use of computer/video games were related to lower self-perception and social-perception. Excessive TV watching was associated with more internalizing problems. Students classified as obese were more likely to report low self- and social-perception, and to experience fewer externalizing problems relative to students classified as normal weight. This study demonstrates independent influences of diet quality, physical activity, sedentary behaviour and body weight on four aspects of self-esteem among children. These findings suggest that school programs and health promotion strategies that target health behaviours may benefit self-esteem in childhood, and mental health and quality of life later in life.

    To examine school- and student-level correlates of physical activity. Cross-sectional Year 2 data collected from 45 298 grade 9-12 students attending 89 secondary schools in the COMPASS study were examined using multi-level modelling to predict the likelihood of students a) achieving 60 minutes of moderate to vigorous physical activity (MVPA) daily; and b) achieving the Canadian Society for Exercise Physiology (CSEP) activity guideline for youth (60 minutes/MVPA daily, vigorous physical activity at least three days in a week, and resistance training at least three days in a week). The prevalence of students achieving 60 minutes of MVPA daily and meeting the CSEP guideline was 49.3% and 31.0% respectively. Modest between-school variability was identified (1.1% for 60 minutes MVPA and 0.8% for CSEP guideline). School-level characteristics significantly associated with the outcome measures included location, school size, quality of facilities, and accessibility of facilities. Significant student-level correlates included sex, grade, weekly income, binge drinking, fruit and vegetable consumption, and body mass index. Most youth in this large study reported inadequate physical activity levels. Students were more likely to achieve 60 minutes of MVPA if they attended a larger school or a school in an urban location, whereas students were less likely to meet the CSEP guideline if they attended a school in a small urban location. However, student-level factors, such as binge drinking and inadequate fruit and vegetable consumption, were more strongly associated with the outcomes examined.

    Alternative lifestyles are often associated with distinct practices with respect to nutrition, physical activity, smoking, alcohol use and usage of complementary medicine. Evidence concerning effects of these lifestyle-related practices on health status is still fragmentary. To describe maternal health characteristics related to alternative lifestyles, with emphasis on body-weight status, during pregnancy and maternity periods. We compared self-reported health-related features of mothers with alternative lifestyles and conventional lifestyles during pregnancy and maternity period in the KOALA Birth Cohort Study. This cohort comprises two recruitment groups of mother-infant pairs, one with a conventional (no selection based on lifestyle, n = 2333), the other with an alternative lifestyle (selected via organic food shops, anthroposophic clinicians and midwives, anthroposophic under-five clinics, Rudolf Steiner schools and relevant magazines, n = 485). Mothers in the alternative group more frequently chose organic foods, adhered to specific living rules, practised vegetarianism and identified themselves with anthroposophy. Mothers in the alternative group showed lower BMI and lower prevalence of overweight and obesity than the conventional group, before pregnancy as well as 4-5 years after delivery. This difference was partly retained after adjusting for potential confounders. Furthermore, women in the alternative group had a lower prevalence of pregnancy-related hypertension, more often started breastfeeding and gave exclusive and prolonged breastfeeding for a longer period. Finally, they smoked less often, but more often drunk alcohol during pregnancy. The results suggest that an alternative lifestyle is associated with favourable body weight and with several differences in other health features.

    Full Text Available In Mexico, basic schooling is composed of three levels: infant (or preschool education, primary (or elementary education and secondary (or middle school education, each taught at a different educational establishment. Students egressing from elementary school are (in average between 12 to 13 years-old, an age of profound changes to which the following can be added: a different educational establishment, different class mates/peers, higher organizational specialization and class work strategies which, in turn, result in a higher number of teachers. Secondary schools have harder institutional structures and higher disciplinary control, so that students seek new ways of negotiation. This article elaborates on those experiences, on how control over appearance, place and body movements influences students through spokesmen and norms, and how body control effectively 'becomes part' of daily class work. I use an ethnographic approach enriched by the categories of Actor-Network Theory (ANT, which allows visualization of the passage of students from one level to another as a network of paths and routes in tension transcending space scales and measured time. It is assumed that students will also build its action context.This paper is written in Spanish.

    Studies based on Body Mass Index (BMI) and waist circumference (WC) are generally used to examine the prevalence and tendency of overweight and obesity. These studies help determine the socioeconomic development of a country and improve public health policies. Therefore, the goal of this research was to determine the trend of change in abdominal obesity of Chilean university students according to the Body Mass Index (BMI) measured in intervals of three and six years. For this study, a total of 1598 students of both sexes ranging in age from 18 to 26 from a Chilean university were evaluated. Students were assessed commencing in 2007 (372 males and 315 females), 2010 (250 males and 330 females), and ending in 2013 (153 males and 178 females). During the three transversal assessments, weight, height, and waist circumference were evaluated. BMI was calculated for both sexes. No significant differences were found in age and BMI during the three years evaluated (2007, 2010, and 2013). In 2013, waist circumference (WC) increased significantly (p obese), the university students showed significant increases in WC (Females: p = 0.004; Males: p = 0.035) whereas in 2007 and 2010, the values remained relatively stable. BMI remained constant during 2007, 2010, and 2013. However, the university students of both sexes showed greater risk of abdominal obesity as a result of increased WC in 2013.

    Introduction Empathy among medical practitioners has been shown to affect patient care and outcomes. Factors such as stress and depression are known to have a negative impact on medical student empathy. Approaches such as mindfulness, meditation, and other mind-body techniques can enhance empathy and reverse burnout symptoms. In the present study, we evaluated impact of Mind Body Medicine (MBM) course on perceived stress and empathy on first-year medical students. Methods Thirteen first-year medical students in total self-selected into MBM (experimental) and seven non-MBM (control) groups completed a prospective, pre- and post-test analysis, using the Jefferson Scale of Physician Empathy - Students (JSPE-S), Perceived Stress Scale (PSS), and Personal Health Questionnaire (PHQ) to evaluate empathy, stress, and depression, respectively. Results Our results showed an increase in stress, as well as a decrease in empathy, in both MBM and non-MBM groups throughout the course of the study. Conclusion Our study demonstrated that the inverse relationship increased stress and decreased empathy among first-year medical students and participation in the MBM course did not attenuate the changes. However, a statistically significant rise in the depression score in the non-MBM group was not observed in the MBM group.

    The purpose of this study was to examine medical students' perceptions of team-based learning (TBL) according to their individual characteristics: gender, team efficacy, interpersonal understanding, proactivity in problem solving, and academic ability. Thirty-eight second-year medical students who took an integrated cardiology course participated in this study; 28 were male and 10 were female. A questionnaire on individual characteristics and a questionnaire on the perception of TBL were administered, and the scores of individual characteristics were grouped into three: high, middle, and low. The data were analyzed by t-test, analysis of variance, and multiple regression analysis. The TBL efficacy perception scale consisted of 3 factors: team skill, learning ability, and team learning. The group of male students and the group of students with high academic ability recognized the effect of TBL on improvements in learning ability more than females and those with low academic ability. The group of students with high team efficacy reported that TBL was effective with regard to team skill improvement. The group of students with high scores on interpersonal understanding and high proactive problem solving tended to perceive the TBL's effect on team skill improvement. Team efficacy and proactivity in problem solving had a positive effect on the perception of TBL. Medical students' perceptions of the effectiveness of TBL differ according to individual characteristics. The results of this study suggest that these individual characteristics should be considered in planning of team learning, such as TBL, to have a positive impact and stronger effects.

    2016-07-01

    Research on occupational therapy students has often been concerned with quite narrow topics. However, the basic characteristics of this group are yet to be examined in more depth. This study aimed to explore the sociodemographic, education-related, and work-related characteristics of occupational therapy students. A sample of 160 occupational therapy students in Norway participated. Differences between cohorts of students were examined with one-way analyses of variance (ANOVA) for continuous variables and with chi-square tests for categorical variables. The sample had a mean age of 24 years and was predominantly female (79%). More than one -third of the students had one or both parents in an occupation requiring health education, whereas two-thirds of the students had one or both parents in an occupation requiring higher education. At entry, 57% of the participants had occupational therapy as their preferred choice of education and 43% had previous higher education experience. The few significant differences between the study cohorts were negligible. In the education programmes, specific attention may be considered for students with characteristics associated with increased risk of poorer study performance or other problems. This may concern male students and students with no previous higher education experience.

    We retrospectively investigated the clinical characteristics and outcome of pneumothorax after stereotactic body radiotherapy (SBRT) for lung tumors. Between April 2003 and July 2012, 473 patients with lung tumors were treated with SBRT. We identified 12 patients (2.5 %) with pneumothorax caused by SBRT, and evaluated the clinical features of pneumothorax. All of the tumors were primary lung cancers. The severity of radiation pneumonitis was grade 1 in 10 patients and grade 2 in two patients. Nine patients had emphysema. The planning target volume and pleura overlapped in 11 patients, and the tumors were attached to the pleura in 7 patients. Rib fractures were observed in three patients before or at the same time as the diagnosis of pneumothorax. The median time to onset of pneumothorax after SBRT was 18.5 months (4-84 months). The severity of pneumothorax was grade 1 in 11 patients and grade 3 in one patient. Although pneumothorax was a relatively rare late adverse effect after SBRT, some patients demonstrated pneumothorax after SBRT for peripheral lung tumors. Although most pneumothorax was generally tolerable and self-limiting, careful follow-up is needed.

  1. Improving the Dynamic Characteristics of Body-in-White Structure Using Structural Optimization

    Directory of Open Access Journals (Sweden)

    Aizzat S. Yahaya Rashid

    2014-01-01

    Full Text Available The dynamic behavior of a body-in-white (BIW structure has significant influence on the noise, vibration, and harshness (NVH and crashworthiness of a car. Therefore, by improving the dynamic characteristics of BIW, problems and failures associated with resonance and fatigue can be prevented. The design objectives attempt to improve the existing torsion and bending modes by using structural optimization subjected to dynamic load without compromising other factors such as mass and stiffness of the structure. The natural frequency of the design was modified by identifying and reinforcing the structure at critical locations. These crucial points are first identified by topology optimization using mass and natural frequencies as the design variables. The individual components obtained from the analysis go through a size optimization step to find their target thickness of the structure. The thickness of affected regions of the components will be modified according to the analysis. The results of both optimization steps suggest several design modifications to achieve the target vibration specifications without compromising the stiffness of the structure. A method of combining both optimization approaches is proposed to improve the design modification process.

    The impact of device parameters on the switching characteristics of negative capacitance ultra-thin-body (UTB) germanium-on-insulator (NC-GeOI) MOSFETs is analyzed. NC-GeOI MOSFETs with smaller gate length (L g), EOT, and buried oxide thickness (T box) and thicker ferroelectric layer thickness (T FE) exhibit larger subthreshold swing improvements over GeOI MOSFETs due to better capacitance matching. Compared with GeOI MOSFETs, NC-GeOI MOSFETs exhibit better switching time due to improvements in effective drive current (I eff) and subthreshold swing. NC-GeOI MOSFET exhibits larger ST improvements at V dd = 0.3 V (-82.9%) than at V dd = 0.86 V (-9.7%), because NC-GeOI MOSFET shows 18.2 times higher I eff than the GeOI MOSFET at V dd = 0.3 V, while 2.5 times higher I eff at V dd = 0.86 V. This work provides the device design guideline of NC-GeOI MOSFETs for ultra-low power applications.

    This investigation purpose was to study degradation characteristics of poly-(caprolactone -chitosan-hydroxyapatite) biomaterial in simulated body fluid (SBF) solution. A composite membrane has been synthesized using blending and stirring method with acetic acid solvent and then molded into thin film. Electron beam radiation dose 0 - 30 kGy were done in order to evaluate radiation effects. SBF absorption with various immersing times and degradation for 0 -12 weeks were conducted. Fourier Transform Infra Red Spectroscopy (FTIR) was used to identification functional groups of composite and Scanning Electron Microscopy (SEM) was applied to analyse micro structural surface of membrane before and after immersion. The irradiation process indicate that SBF absorption decrease because NH 2 groups in chitosan which contributes to the hydrophilicity was broken. The composite III indicate maximum absorption (58,2% ± 2,22) due to its smallest concentration of polycaprolactone and highest concentration of chitosan that caused decrease of hydrophobicity. Optimum degradation of composite III (1,3% ± 0,98) was reached after 8 weeks of immersion time. FTIR spectrum indicate the unity of typical peaks of the constituent materials and specific spectrum of CO 3 2- of carbonated apatite which was formed because immersion of SBF. Microstructural analysis using SEM indicate the formation of needle like apatite layer or calcium phosphate precipitate over all surface membrane. All the results indicate that these composite meet the requirements to biomaterial. (author)

    Stress affects the well-being of both nursing students and the individuals with whom they work. With the theory of cognitive appraisal as a framework for this study, it is proposed that mind-body self-care strategies promote stress management by stabilization of emotions. Outcomes will be a perception of less stress and more mindful engagement with the environment. Objective of the study was to describe an evaluation of student perceived stress and mindfulness to 1-hour per week of class time dedicated to mind-body self-care (yoga, mindful breathing, Reiki, and essential oil therapy). It was a quasi-experimental study; data collection took place at 4 time points. Participants were entry-level accelerated nursing students from 3 US universities: 50 in the treatment group, 64 in the comparison group. Data included health-promoting practices using Health-Promoting Promotion Lifestyle Profile II as a control variable, stress and mindfulness (Perceived Stress Scale [PSS] and Mindful Attention Awareness Scale [MAAS]), and demographic information; analysis using mixed-design repeated-measures analysis of variances. There was a statistically significant interaction between intervention and time on PSS scores, F(3, 264) = 3.95, P = .009, partial η(2) = 0.043, with PSS scores of the intervention group decreasing from baseline to T3 when intervention ended whereas PSS scores of the comparison group increased from baseline. The average scores on the MAAS did not differ significantly. Evaluation of an embedded mind-body self-care module in the first nursing course demonstrated promising improvements in stress management. The findings support the appropriateness of integrating mind-body self-care content into nursing curricula to enhance students' ability to regulate stress.

    The study investigated the relationship between body mass index and self-concept among adolescent black female university students. The study used a mixed research design (quantitative and qualitative methods). Media images of handsome faces and beautiful bodies are used to sell almost everything, from clothes and cosmetic to luncheon, meats, and so on. These images reinforce the western cultural stereotype that women should be thin and shapely to be attractive. Thus, as some girls go through puberty they may become dissatisfied with their weight, and to a lesser extent, with their shape, thus, developing low self-concept or imae of themselves. It is in this context that the study was conceptualised. First year female students from three different Schools and Faculties at the University of Limpopo, Turfloop Campus, South Africa, participated in the study. Using the availability and convenient sampling method, 75 students were selected for this study. For the quantitative aspect of the study, the Rosenberg Self-esteem Measure was used to measure self-esteem. For the qualitative part, a topic guide was used for the focus group discussions. Analysis of Variance (ANOVA) and the Pearson's Product Moment Correlation were used to analyse the quantitative data, while the phenomenological principle of open coding used for the thematic analysis. Results showed that there is a relationship between body mass and self-concept and that overweight participants tend to have a low self-esteem. Low self-esteem was perceived to be aggravated by a number of factors, like the attitude of the media and the society. Participants who are overweight also indicated that they are limited in certain activities of daily living (e.g., sports) as a result of their body mass. They expressed mixed feelings and frustration when it comes to such activities. The above results did not differ from those reported from western cultures. Support groups, life-skills programmes and psychotherapy should be

    To assess eating habits and the level of physical activity in adolescents and develop a predictive model for the body mass index (BMI) based on these variables. In this cross-sectional study, eating habits and the level of physical activity were assessed using a questionnaire validated in adolescents. Body mass and height collected during the last annual checkup were extracted from personal medical records. The sample included 330 boys and 377 girls (mean age 15.8 ± 0.2 years) who were first-year high school students in the city of Belgrade, Serbia. Responses to each of the 14 questions about eating habits and 6 questions about physical activity were scored from the least (0) to the most (3) desired behaviors. These ratings were then averaged to arrive to an aggregate score for each domain. The BMI was calculated according to the standard method. A series of regression analyses was performed to derive the best model for predicting BMI in boys and girls based on individual eating habits and physical activity items, first separately and then combined. In the sample, 24.5% of boys and 9.5% of girls were overweight or obese. Girls' eating habits were better than boys (mean aggregate score 2.3 ± 0.3 and 2.1 ± 0.3, respectively, p physical activity was greater in boys than girls (2.1 ± 0.6 vs 1.9 ± 0.6, p boys and girls in the BMI, eating habits, and physical activity remained significant after controlling for their knowledge about healthy eating and education level of their parents. Eating habits were a better predictor of BMI than physical activity, particularly in boys (R (2) = 0.13 vs R (2) = 0.02) compared to girls (R (2) = 0.04 vs R (2) = 0.01). Combining eating habits and physical activity in the multivariate model of BMI resulted in a better predictive accuracy in boys (R (2) = 0.17) but not girls (R (2) = 0.04). Eating habits and physical activity differ between adolescent boys and girls and can predict BMI, particularly in boys. The results suggest the

    This study compared changes in the body size and physical characteristics of South African under-20 rugby union players over a 13-year period. A total of 453 South African under-20 players (forwards: n = 256 and backs: n = 197) underwent measurements of body mass, stature, muscular strength, endurance, and 10- and 40-m sprint times. A 2-way analysis of variance was used to determine significant differences for the main effects of position (forwards vs. backs) and time (1998-2010). The pooled data showed that forwards were significantly heavier (22%), taller (5%), and stronger (18%) than the backs. However, when 1 repetition maximum strength scores were adjusted for body mass, backs were stronger per kg body mass. Stature did not change over the 13-year period for both groups. There were, however, significant increases in muscular strength (50%), body mass (20%), and muscular endurance (50%). Furthermore, an improvement in sprint times over 40 (4%) and 10 m (7%) was evident over the period of the study. In conclusion, the players became heavier, stronger, taller, and improved their upper-body muscular endurance over the 13 years of the study. Furthermore, sprint times over 10 and 40 m improved over the same time period despite the increase in body mass. It can be speculated that the changes in physical characteristics of the players over time are possibly a consequence of (a) adaptations to the changing demands of the game and (b) advancements in training methods.

    In the studies of acceleration conducted so far a multidimensional perspective has largely been neglected. No attempt has been made to relate social-emotional characteristics of accelerated versus non-accelerated students in perspective of environmental factors. In this study, social-emotional characteristics of accelerated gifted students in the Netherlands were examined in relation to personal and environmental factors. Self-concept and social contacts of accelerated (n = 148) and non-accelerated (n = 55) gifted students, aged 4 to 27 (M = 11.22, SD = 4.27) were measured. Self-concept and social contacts of accelerated and non-accelerated gifted students were measured using a questionnaire and a diary, and parents of these students evaluated their behavioural characteristics. Gender and birth order were studied as personal factors and grade, classroom, teachers' gender, teaching experience, and the quality of parent-school contact as environmental factors. The results showed minimal differences in the social-emotional characteristics of accelerated and non-accelerated gifted students. The few differences we found favoured the accelerated students. We also found that multiple grade skipping does not have negative effects on social-emotional characteristics, and that long-term effects of acceleration tend to be positive. As regards the possible modulation of personal and environmental factors, we merely found an impact of such factors in the non-accelerated group. The results of this study strongly suggest that social-emotional characteristics of accelerated gifted students and non-accelerated gifted students are largely similar. These results thus do not support worries expressed by teachers about the acceleration of gifted students. Our findings parallel the outcomes of earlier studies in the United States and Germany in that we observed that acceleration does not harm gifted students, not even in the case of multiple grade skipping. On the contrary, there is a

    In clerkships, students are expected to self-regulate their learning. How clinical departments and their routine approach on clerkships influences students' self-regulated learning (SRL) is unknown. This study explores how characteristic routines of clinical departments influence medical students' SRL. Six focus groups including 39 purposively sampled participants from one Dutch university were organized to study how characteristic routines of clinical departments influenced medical students' SRL from a constructivist paradigm, using grounded theory methodology. The focus groups were audio recorded, transcribed verbatim and were analyzed iteratively using constant comparison and open, axial and interpretive coding. Students described that clinical departments influenced their SRL through routines which affected the professional relationships they could engage in and affected their perception of a department's invested effort in them. Students' SRL in a clerkship can be supported by enabling them to engage others in their SRL and by having them feel that effort is invested in their learning. Our study gives a practical insight in how clinical departments influenced students' SRL. Clinical departments can affect students' motivation to engage in SRL, influence the variety of SRL strategies that students can use and how meaningful students perceive their SRL experiences to be.

    Body dissatisfaction in females, and to a lesser extent males, is associated with low self-esteem, depression, and eating disorders. This research examined gender as a moderator of the association between contingent self-esteem and body image concerns, including weight and muscularity. Participants included 359 (59.1% female) heavy drinking first-year U.S. undergraduate students who completed a survey assessing health-related risk behaviors. Hierarchical multiple regression was used to examine relations among gender, contingent self-esteem, and body image. Females reported higher levels of contingent self-esteem and greater concerns about their weight, although males reported a greater drive for muscularity. The relationship between contingent self-esteem and weight concerns was stronger among females, and for males, greater contingent self-esteem was associated with a greater drive for muscularity.

    The objective of the study was to investigate the prevalence of overweight issues and obesity by recording the body mass index (BMI) and explore the dietary habits, physical activities (PAs), and lifestyles of male students at the College of Dentistry, King Saud University. A custom-designed self-administrative form and questionnaire were used in this study for data collection. The first part of the form was used to record the participants' height and weight for the BMI. The participants were grouped as underweight (BMI 30.0). The second part comprised questions related to the dietary habits, PAs, and lifestyles of the male dental students. Chi-squared test was used to generate the significance of each question at significance surfing per day (p = 0.012). The prevalence of overweight issues and obesity is high among the dental students compared with the general population of Saudi Arabia, and there is a need for intervention programs to combat obesity among the dental students. The awareness about PA, healthy diet/lifestyle, consequences of overweight and obesity on their health and profession must be increased among the dental students to avoid future complications. The impact of obesity on individuals' oral health and its influence on dental treatment protocols and postoperative procedures has been well documented. Dental students are more prone to obesity due to their lifestyle with less PA and disordered eating habits and, thereby, are prone to obesity-related health hazards.

    In the health professions, competency in communication skills is necessary for the development of a satisfactory physician-patient interaction. Body expression is an important domain of the communication process, often not adequately addressed. The aim of this study was to describe the methodology and content of a pilot introductory training session in body expression for dental students before the beginning of their clinical training. The educational methods were based on experiential learning and embodied training, where the session's content focused on five themes representing different phases of the dental treatment session. A questionnaire was distributed before and after the session to assess any changes in students' self-perceptions in communication skills. There were statistically significant improvements in the total values of the students self-perceptions of their communication skills obtained before and after the training and in specific elements such as small group situations, performing an interview, understanding the feelings of others and expressing one's own feelings. The dental students in the present study felt that this preclinical experiential learning session improved their communication skills. The feedback from this training experience will enable further development of an effective communication course for clinical dentistry.

    Full Text Available Background: Migraine is a common neurological disorder with significant impact on quality of life. The aim of this study was to investigate the prevalence and characteristics of migraine headaches in medical students, to measure its impact on their life, and to assess their knowledge about the ailment. Information about lifestyle variables was also collected. Materials and Methods: All medical students who confirmed of having headache for more than 1 year formed the study group. Students filled a detailed questionnaire focusing on demographics, pain characteristics, accompanying factors, triggers, and family history of migraine. Lifestyle variables were enquired and migraine associated disability was assessed by MIDAS (Migraine Disability Assessment. The diagnosis of migraine was made according to the International Headache Society criteria. Results are expressed in n = numbers and percentage. Results: Sixty-eight percent of medical students had headache. The prevalence of migraine in the whole cohort was 28%; however, of the headache group, migraine constituted 42%. There was a female preponderance. One-fourth of the students had weekly or daily attacks with 31% students reporting increase in their headache intensity and frequency. Forty-four percent of students had severe headaches. Dizziness, allodynia, and neck stiffness were reported as accompanying symptoms. Trigger factors were identified in 99% students, predominant of which were poor sleep hygiene, environmental changes, head movements, and mental stress. Only 4% of students did regular exercise. Twenty-seven percent of students reported self-medication use of analgesics. One-fourth of the students had migraine-associated disability but only 6% realized that they had migraine. Conclusion: Our study found a high prevalence of headache with migraine in medical students. The students′ awareness of the disease was very low with one-fourth of the students resorting to self-medication. Our

    The use of sugar by dental plaque microorganisms leads to acid formation from the bacteria metabolism, which determines a decrease of pH onto teeth surfaces. The value of the critical pH is 5.2-5.5. We aimed to evaluate the capacity of patients to change their diet towards caries prevention after acknowledging the values of saliva parameters (pH, buffer capacity). A group of 52 subjects were clinically examined according to the International Caries Assessment and Detection System protocol. They were required to complete a diet questionnaire and salivary tests were made for the oral mucosa hydration level, pH, buffer capacity, salivary flow rate at rest and upon stimulation. 4 pre-calibrated 6th year students and 2 dentists performed the tests and the ICDAS examination. One week after the tests, the subjects were asked to complete the diet questionnaire again. The studied group consisted of students aged between 23-26 years, randomly selected among 6(th) year students of the Faculty of Dentistry from Cluj-Napoca. The mean DMF-S index was 18.39. Most of the patients (65%) had a DMF-S index between 9 and 21. Just 2.5% had an index of 3, which was the lowest value recorded. 5% of the patients had a DMFS of 35, which was the maximal value recorded. The distribution of DMF-S was normal. 50% of the patients had no active caries. Even though most subjects (19.23%) had a pH within the normal interval, most of them were at the bottom value of the interval (6.8). Most subjects had a pH of 6.4, which is moderately acid. The mean pH was 6.7, therefore, a moderately acid one. The Pearson correlation coefficient between DMFS and pH was 0.255. A mild negative correlation (-0.275) was found between the cariogenic food and buffer capacity. A week later we noticed a statistically significant decrease of cariogenic foods and drinks in students with acid pH and with low buffer capacity. A regular intake of cakes, bonbons and chocolate was reported by subjects who had a high DMF-S value

    To estimate the contribution of sociodemographic and labor variables and body mass index to body image concern. In order to estimate body image concern, the Body Shape Questionnaire (BSQ) and the Weight Concerns Scale (WCS) were applied. A confirmatory factor analysis of scales was carried out. The reason χ2 by degree of freedom ratio (χ2/df ), Comparative Fit Index (CFI), Normed Fit Index (NFI), and root mean square error of approximation (RMSEA) were used. Convergent validity was assessed through the average variance extracted and composed reliability and the internal consistency through standardized Cronbach's alpha coefficient (α). A structural model was developed, and the body image concern was the second-order main construct. The model appropriation was evaluated based on the goodness-of-fit indices. The z test was used to estimate the significance of trajectories (β) using a 5% significance level. Totally, 595 female college students participated in the study, with a mean age of 20.42 ± 2.44 years. The entire model, with the inclusion of all independent variables, showed unsatisfactory adjustment and was refined. The final model presented a satisfactory adjustment (χ2/df = 5.75; CFI = 0.87; NFI = 0.85; RMSEA = 0.09) with inclusion of medication use because of studies (β = 0.08; p = 0.04), academic performance (β = 0.09; p = 0.02), economic class (β = 0.08; p = 0.03), and body mass index (β = 0.44; p concern. Medication use due to studies, academic performance, economic class and body mass index significantly contribute to body image concern.

    Stevens, Joseph J; Schulte, Ann C

    This study examined mathematics achievement growth of students without disabilities (SWoD) and students with learning disabilities (LD) and tested whether growth and LD status interacted with student demographic characteristics. Growth was estimated in a statewide sample of 79,554 students over Grades 3 to 7. The LD group was significantly lower in achievement in each grade and had less growth than the SWoD group. We also found that student demographic characteristics were significantly related to mathematics growth, but only three demographic characteristics were statistically significant as interactions. We found that LD-SWoD differences at Grade 3 were moderated by student sex, while Black race/ethnicity and free or reduced lunch (FRL) status moderated LD-SWoD differences at all grades. These results provide practitioners and policy makers with more specific information about which particular LD students show faster or slower growth in mathematics. Our results show that simply including predictors in a regression equation may produce different results than direct testing of interactions and achievement gaps may be larger for some LD subgroups of students than previously reported.

    Full Text Available We summarize the results of socio-psychological studies of classroom management, performed on the basis of a theoretical model of value exchange, developed by R.L.Krichevsky. Classroom management is understood as a kind of management activity of a teacher, aimed at organizing group of students. Factor analysis revealed two major factors of the effectiveness of classroom management: the nature of the relationship between the students and their relations to the class teacher. As teacher’s activity characteristics, we considered manifestations of his attitudes toward students, leadership style, characteristics of individual interaction with students. It is shown that the activity of the class teacher, aimed at meeting the critical social needs of students, has two major dimensions: taking care about students and development of their motivation. We analyze the impact of social and perceptual characteristics of the teacher on the effectiveness of his interaction with students. We reveal the features of self-assessment and reflective evaluation of personality and activity of a class teacher, the specifics of causal attributions of success and failure of students in different areas of school life.

    2015-01-01

    Highlights: • Characteristics of C 3 H 8 –H 2 bluff-body stabilized flames are investigated. • Decreasing the bluff-body lip thickness led into enhanced flame length. • CO mass fraction is increased with reducing hydrogen content in the fuel stream. • Augmenting hydrogen content increased the maximum temperature. • Jet-like zone in propane–hydrogen bluff-body stabilized flames is very unstable. - Abstract: At the beginning of this study, the well-known turbulent bluff-body stabilized diffusion flame of HM1 is simulated by a coupled flamelet/radiation approach. The HM1 flame comprises a CH 4 :H 2 [50:50 Vol.] jet flame at a Reynolds number of 15,800. The results showed reasonable agreement for the flow field and species. Afterwards, the abovementioned approach is employed to investigate the effects of hydrogen addition on bluff-body stabilized flames of propane–hydrogen. Adding hydrogen to the blended fuel of propane/hydrogen shifts the recirculation zone outwards the bluff-body and thus culminates in increased flame length. Besides this, the flame length is predicted to be enhanced with decreasing the lip thickness of the bluff-body configuration. The CO emission level is found to be decreased with hydrogen addition in near-burner and far field regions which might be attributed to the decrease of inflow carbon atoms. The local radiative heat power reveals higher values for fuel blends with decreased contents of hydrogen at the recirculation and jet-like zones. This might be attributed to the increased local heat release rate due to breaking further carbon bonds

    Research on the built food environment and weight status has mostly focused on the presence/absence of food outlets while ignoring their internal features or where residents actually shop. We explored associations of distance travelled to supermarkets and supermarket characteristics with shoppers' body mass index (BMI). Shoppers (n=555) of five supermarkets situated in different income areas in the city were surveyed for food shopping habits, demographics, home postal code, height and weight. Associations of minimum distance to a supermarket (along road network, objectively measured using ArcGIS), its size, food variety and food basket price with shoppers' BMI were investigated. The 'food basket' was defined as the mixture of several food items commonly consumed by residents and available in all supermarkets. Supermarkets ranged in total floor space (7500-135,000 square feet) and had similar varieties of fruits, vegetables and cereals. The majority of participants shopped at the surveyed supermarket more than once per week (mean range 1.2 ± 0.8 to 2.3 ± 2.1 times per week across the five supermarkets, p supermarkets ranged from 23.7 ± 4.3 kg/m² to 27.1 ± 4.3 kg/m² (p supermarket they shopped at ranged from 0.96 (0.57, 2.31) km to 4.30 (2.83, 5.75) km (p supermarket, or other supermarket characteristics. After adjusting for age, sex, dissemination area median individual income and car ownership, BMI of individuals who shopped at Store 1 and Store 2, the supermarkets with lowest price of the 'food basket', was 3.66 kg/m² and 3.73 kg/m² higher compared to their counterparts who shopped at the supermarket where the 'food basket' price was highest (p supermarkets was inversely associated with BMI of their shoppers. Our results suggest that careful manipulation of food prices may be used as an intervention for decreasing BMI.

    Full Text Available This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32. The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively. The tests were applied (two-factor ANOVA to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104 and self-esteem (p=0.09 were considered significant. The results demonstrated that age negatively correlated with body dissatisfaction (r=-0.19; p<0.01 and that higher body mass index levels were associated with greater body dissatisfaction (r=0.15, p=0.016 and lower levels of self-esteem (r=-0.17, p<0.01 only in non-practitioners. The practice of dance had a significant effect on levels of body dissatisfaction (F=4.79; p=0.030; η2=0.02, but there was no significant difference in self-esteem (F=1.88; p=0.172; η2=0.02. It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the nonpractitioners group.

    Eating Disorders (EDs) are serious psychiatric illnesses marked by psychiatric comorbidity, medical complications, and functional impairment. Research indicates that female athletes are often at greater risk for developing ED pathology versus non-athlete females. The Female Athlete Body (FAB) study is a three-site, randomized controlled trial (RCT) designed to assess the efficacy of a behavioral ED prevention program for female collegiate athletes when implemented by community providers. This paper describes the design, intervention, and participant baseline characteristics. Future papers will discuss outcomes. Female collegiate athletes (N=481) aged 17-21 were randomized by site, team, and sport type to either FAB or a waitlist control group. FAB consisted of three sessions (1.3h each) of a behavioral ED prevention program. Assessments were conducted at baseline (pre-intervention), post-intervention (3weeks), and six-, 12-, and 18-month follow-ups. This study achieved 96% (N=481) of target recruitment (N=500). Few group differences emerged at baseline. Total sample analyses revealed moderately low baseline instances of ED symptoms and clinical cases. Health risks associated with EDs necessitate interventions for female athletes. The FAB study is the largest existing RCT for female athletes aimed at both reduction of ED risk factors and ED prevention. The methods presented and population recruited for this study represent an ideal intervention for assessing the effects of FAB on both the aforementioned outcomes. We anticipate that findings of this study (reported in future papers) will make a significant contribution to the ED risk factor reduction and prevention literature. Copyright © 2017 Elsevier Inc.

    Full Text Available In order for the working status of the aluminum alloyed hydraulic valve body to be controlled in actual conditions, a new friction and wear design device was designed for the cast iron and aluminum alloyed valve bodies comparison under the same conditions. The results displayed that: (1 The oil leakage of the aluminum alloyed hydraulic valve body was higher than the corresponding oil leakage of the iron body during the initial running stage. Besides during a later running stage, the oil leakage of the aluminum alloyed body was lower than corresponding oil leakage of the iron body; (2 The actual oil leakage of different materials consisted of two parts: the foundation leakage that was the leakage of the valve without wear and wear leakage that was caused by the worn valve body; (3 The aluminum alloyed valve could rely on the dust filling furrow and melting mechanism that led the body surface to retain dynamic balance, resulting in the valve leakage preservation at a low level. The aluminum alloy modified valve body can meet the requirements of hydraulic leakage under pressure, possibly constituting this alloy suitable for hydraulic valve body manufacturing.

    School bullying is the most common school violence among adolescents and has become a global concern. Little is known about the characteristics associated with bullies and victims among Jordanian students. The aim of the study was to examine student perceptions of school bullying-specifically, the characteristics of perpetrators and victims and how to stop bullying-and assess differences in perceptions between boys and girls. Cross-sectional study, using self-reported questionnaires, was employed to collect data from eighth-grade students (N = 913; 51% male) from a mixed rural and suburban area in northern of Jordan during the 2013-2014 school year. Descriptive statistics were used to summarize item responses. Chi-squared tests were performed to compare responses between the male and female students. Most of the students described a bully as one who is a coward underneath (78.9%), lacks respect for other people (70%), wants to show power (67.5%), wants to impress others (60.8%), and wants to feel superior (59.6%). Students perceived victims of bullying as having low self-esteem (68.2%), talking or sounding different than others (50.9%), shy (35%), and having no friends (27.1%). Students suggested that, to stop bullying, the victim should stand up for himself (75.4%), should become psychologically stronger (75.1%), and should involve adults (teachers, family, or others; 45.9%). There was a significant gender difference, in which boys and girls were describing victims and bullies differently. A significant percentage of students relate bullying and victimization characteristics to psychosocial characteristics and less to physical characteristics. The results offer valuable information necessary to design and implement school bullying prevention and intervention programs.

    Full Text Available Background: At present, the portfolio of devices using the bioelectrical impedance (BIA method is continuously expanding as a result of the wide use of this method in the field as measurements by this method are fast and staff training is simple and reasonably priced. Nonetheless, the problem is that despite using the same method, bioimpedance analyzers can differ in many parameters. They use different electric current frequencies, a different number of electrodes and the electric current may be conducted through different parts of the body.Objective: The main objective of the study is to compare and evaluate the differences of values of the analysis of the body fat of university students measured by BIA analyzers that differ in the applied electric current frequency, number of electrodes and flow of the electric current through the individual body parts.Methods: The research included 125 participants (70 male and 55 female. The measurements were taken by the following analyzers: Tanita 418 MA, InBody 720, InBody R20 and Omron BF 300.Results: The differences in the mean values of the body fat representation between the used analyzers in men ranged from 0.1 to 3.4% and from 0.0 to 2.4 kg, in women from 0.5 to 6.5% and from 0.4 to 3.8 kg in relation to the used analyzer.Conclusions: In men with regular physical activity, the values measured by InBody R20 were statistically and practically different. The analyzer measured higher values that other analyzers. In women, there were statistically and practically significant differences in the values measured by Omron BF 300. This analyzer measured lower values than other analyzers.

    2010-10-15

    The implementation of a geodata-based probabilistic pesticide exposure assessment for surface waters in Germany offers the opportunity to base the exposure estimation on more differentiated assumptions including detailed landscape characteristics. Since these characteristics can only be estimated using field surveys, water body width and depth, hydrology, riparian buffer strip width, ground vegetation cover, existence of concentrated flow paths, and riparian vegetation were characterised at 104 water body segments in the vineyard region Palatinate (south-west Germany). Water body segments classified as permanent (n=43) had median values of water body width and depth of 0.9m and 0.06m, respectively, and the determined median width:depth ratio was 15. Thus, the deterministic water body model (width=1m; depth=0.3m) assumed in regulatory exposure assessment seems unsuitable for small water bodies in the study area. Only 25% of investigated buffer strips had a dense vegetation cover (>70%) and allow a laminar sheet flow as required to include them as an effective pesticide runoff reduction landscape characteristic. At 77 buffer strips, bordering field paths and erosion rills leading into the water body were present, concentrating pesticide runoff and consequently decreasing buffer strip efficiency. The vegetation type shrubbery (height>1.5m) was present at 57 (29%) investigated riparian buffer strips. According to their median optical vegetation density of 75%, shrubberies may provide a spray drift reduction of 72±29%. Implementing detailed knowledge in an overall assessment revealed that exposure via drift might be 2.4 and via runoff up to 1.6 fold higher than assumed by the deterministic approach. Furthermore, considering vegetated buffer strips only by their width leads to an underestimation of exposure by a factor of as much as four. Our data highlight that the deterministic model assumptions neither represent worst-case nor median values and therefore cannot

    Living in a world greatly controlled by mass media makes it impossible to escape its pervading influence. As media in Pakistan has been free in the true sense of the word for only a few years, its impact on individuals is yet to be assessed. Our study aims to be the first to look at the effect media has on the body image of university students in a conservative, developing country like Pakistan. Also, we introduced the novel concept of body image dissatisfaction as being both negative and positive. A cross-sectional study was conducted among 7 private universities over a period of two weeks in the city of Karachi, Pakistan's largest and most populous city. Convenience sampling was used to select both male and female undergraduate students aged between 18 and 25 and a sample size of 783 was calculated. Of the 784 final respondents, 376 (48%) were males and 408 (52%) females. The mean age of males was 20.77 (+/- 1.85) years and females was 20.38 (+/- 1.63) years. Out of these, 358 (45.6%) respondents had a positive BID (body image dissatisfaction) score while 426 (54.4%) had a negative BID score. Of the respondents who had positive BID scores, 93 (24.7%) were male and 265 (65.0%) were female. Of the respondents with a negative BID score, 283 (75.3%) were male and 143 (35.0%) were female. The results for BID vs. media exposure were similar in both high and low peer pressure groups. Low media exposure meant positive BID scores and vice versa in both groups (p media exposure and negative body image dissatisfaction. Finally, we looked at the association between gender and image dissatisfaction. Again a statistically significant association was found between positive body image dissatisfaction and female gender and negative body image dissatisfaction and male gender (p media to have an overall negative effect on individuals' body image. A striking feature of our study, however, was the finding that negative body image dissatisfaction was found to be more prevalent in

    Fogle, Thomas Ty

    Research on introductory STEM course performance has indicated that student characteristics (age, ethnicity and gender) and Grade Point Average (G.P.A.) can be predictive of student performance, and by implication, a correlation among these factors can help determine course design interventions to help certain types of students perform well in introductory STEM courses. The basis of this study was a community college Visual Basic programming course taught in both online and hybrid format. Beginning students in this course represented a diverse population residing in a large, mid-western, city and surrounding communities. Many of these students were defined as "at-Risk" or "non-traditional, which generally means any combination of socio-economic, cultural, family and employment factors that indicate a student is non-traditional. Research has shown these students struggle academically in technologically dense STEM courses, and may require student services and support to achieve their individual performance goals. The overall number in the study range was 392 distance students and 287 blended course students. The main question of this research was to determine to what extent student characteristics in a community college context, and previous success, as measured in overall G.P.A., were related to course performance in an introductory Visual Basic programming (STEM) course; and, whether or not a combination of these factors and course modality was predictive of success. The study employed a quantitative, quasi-experimental design to assess whether students' course performance was linked to course modality, student characteristics and overall G.P.A. The results indicated that the only predictor of student performance was overall G.P.A. Despite the research analyzed in Chapter 2, there was no statistically significant relationship to modality, age, ethnicity, or gender to performance in the course. Cognitive load is significant in a computer programming course and it

    Purpose: To determine the distribution and variation of rBMD in human lumbar vertebral body. Methods: The BMD and rBMD of 28 samples of lumbar body were measured with QCT. The rBMD was measured in the regions of anterior, anterolateral, posterolateral and central, superior-level, middle-level and inferior-level of the vertebral bodies. The relationship between BMD and rBMD were statistically analysed with multiple regression. Results: The rBMD of the inferior vertebral body was higher than that of the superior and middle portions (P<0.05); the central and posterolateral higher than the anterior and anterolateral (P<0.05). The rBMD of posterioinferior vertebral body was the highest. The multiple regression showed that the standard partial regression coefficient of inferior was larger than the superior and middle; the anterior and central were larger than the other regions of the vertebra. Variations of the BMD of vertebral body were mostly related to the rBMD of anterior and central parts. Conclusion: The distribution of BMD are heterogeneous in vertebral body. The anterior and central part of vertebral body are most sensitive to bone loss in osteoporosis. It is emphasized that the rBMD of anterior and central part of vertebral body should be measured for following the osteoporosis

    Like normal deltas, fan-deltas are composed of three parts, i.e., fan-delta plain, fan-delta front and pre-fin-delta, In-situ leachable uranium deposits are commonly distributed along the margins of in-land basins. The author analyzes the possible relationship between the basic characteristics of fan-delta sandstone bodies and uranium mineralization. Two examples, e.g., the fan delta depositional systems in the eastern part of Jungger basin and the southern part of Yili basin, are given to illustrate the fan-delta vertical sequence and planar distribution of sedimentary facies. It has been pointed out that the braided channel sandstone bodies on delta plain, sub-aqueous distributional channel sandstone bodies and delta front sandstone bodies may be the favourable host rocks for in-situ leachable sandstone uranium deposits

    Background Work-related musculoskeletal disorders are one of the main occupational health hazards affecting dental practitioners. This study was conducted to assess the prevalence of Work-related Musculoskeletal Disorder (WMSD) amongst dental students. Possible correlations with the working environment and ergonomics taught in Malaysian dental schools were also sought. Methods Five dental schools in Malaysia participated in this cross-sectional study. A validated self-administered questionnaire was used to establish the point prevalence of WMSD in the dental students based on various body regions. The questionnaire also collected data regarding the working environment, clinical practice and the taught ergonomics of the students during their training years. Results Out of five hundred and sixty eight dental students who participated in the study, 410 were in their clinical years whilst 158 were students in their non- clinical years. Ninety three percent of the clinical year students reported symptoms of WMSD in one or more body regions. Female students reported a significantly higher numbers of symptoms compared to male students. The neck (82%) and lower back (64%) were reported to have the highest prevalence of WMSD. Discomfort in the neck region was found to be associated with self-reported frequency of bending of the neck. A majority of students (92%) reported minimum participation in workshops related to ergonomics in dentistry and 77% were unfamiliar with treatment and remedies available in the case of WMSD. Conclusions There was more WMSD seen in dental students who had started their clinical years. Neck and lower back are more injury prone areas and are at increased risk of developing musculoskeletal disorders. Theory and practice of ergonomics should be incorporated into the dental undergraduate curriculum. PMID:23547959

    Medical students' values figure prominently in their choice of medical specialty; yet, little research has been performed on this topic. The purpose of this study was to analyze the differences in values according to medical students' individual characteristics (medical educational system, gender, and grade) and preferred medical specialty. A total of 905 medical students participated in the study; 426 were graduate-entry medical students (GEMS), and 479 were undergraduate medical students (UMS). Further, 561 were male and 316 were female; 356 were in year 1, 219 were in year 2, 230 were in year 3, and 100 were in year 4. Students completed the Physician Values in Practice Scale (PVIPS). The PVIPS comprises six dimensions: autonomy, management, prestige, service, lifestyle, and scholarly pursuits. The data were analyzed by t-test and analysis of variance. GEMS had higher scores for service, management, and scholarly pursuits than UMS. Males had higher scores for prestige, lifestyle, and management, whereas female scored higher on service and scholarly pursuits. Higher grade was associated with increased scores for prestige, lifestyle, and management. The differences in lifestyle and scholarly pursuits were significant between preferred specialties. Students in support specialties scored significantly higher on lifestyle. With regard to scholarly pursuits, basic science specialties scored significantly higher than other specialties. There were significant differences in PVIPS according to individual characteristics and preferred medical specialty. This result could be useful in developing a medical specialty choice program for medical students.

    Online compulsive buying is a little-studied behavioral disorder. To better understand its clinical aspects by focusing on (i) prevalence rate, (ii) correlation with other addictions, (iii) influence of means of access, (iv) motivations to shop to the internet and (v) financial and time-consuming consequences. Cross-sectional study. 200 students in two different centers of Paris Diderot University - Paris VII. Brief self-questionnaires, to screen online compulsive buying, internet addiction, alcohol and tobacco use disorders, to rate frequency of online purchase by private-sale websites, by advertising banners, by mobile phone or to avoid stores, to rate motivations like "more discreet", "lonelier", "larger variety of products", "more immediate positive feelings", and "cheaper" and to assess the largest amount of online purchasing and the average proportion of monthly earnings, and time spent, both day and night. Prevalence of online compulsive buying was 16.0%, while prevalence of internet addiction was 26.0%. We found no significant relationship with cyberdependence, alcohol or tobacco use disorders. Online compulsive buyers accessed more often shopping online by private-sale websites (56.2% vs 30.5%, pmobile phone (22.5% vs 7.9%, p=0.005) and preferred online shopping because of exhaustive offer (p<0.0001) and immediate positive feelings (p<0.0001). Online compulsive buyers spent significantly more money and more time in online shopping. Online compulsive buying seems to be a distinctive behavioral disorder with specific factors of loss of control and motivations, and overall financial and time-consuming impacts. More research is needed to better characterize it. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available The study investigated the relationship between body mass index and self-concept among adolescent black female university students. The study used a mixed research design (quantitative and qualitative methods. Media images of handsome faces and beautiful bodies are used to sell almost everything, from clothes and cosmetic to luncheon, meats, and so on. These images reinforce the western cultural stereotype that women should be thin and shapely to be attractive. Thus, as some girls go through puberty they may become dissatisfied with their weight, and to a lesser extent, with their shape, thus, developing low self-concept or imae of themselves. It is in this context that the study was conceptualised.

    The assumed characteristics of individuals in the adult entertainment industry have been used to advocate positions for and against pornography. Although prior studies have investigated perceptions of porn actors, no data on the actual characteristics of this group exist. The present study compared the self-reports of 105 male and 177 female porn actors to the perceptions of 399 college students on childhood sexual abuse (CSA), self-esteem, work and non-work sexual behaviors, and safe sex issues. College students were asked to identify the characteristics associated with either a male or female porn star. College students provided underestimates for both female and male porn actors on self-esteem, age of first intercourse, lifetime number of partners outside of work, ideal experience in a romantic partner, concerns regarding sexually transmitted diseases (STDs), enjoyment of sex, and condom use during a first time sexual encounter, but overestimated earnings. Additional differences among male porn stars included an underestimate of the number of partners at work. For female porn stars, college students underestimated their enjoyment of work, the probability of catching an STD, and having unprotected sex. Although there were no significant differences on perceived rates of childhood abuse of porn actors, the incidence of CSA among the porn actor participants were within the ranges of the general population. The majority of college student stereotypes were not supported regarding the perceptions of porn actors. These findings were discussed within the context of attributing unfounded characteristics of individuals to an entire industry.

    Full Text Available The body mass index (BMI of school children in Taiwan is markedly increasing. According to statistical data from the Taiwan Ministry of Education, the prevalence of obesity in school children from the southern part of the country is the highest in Taiwan. Thus, exploring the factors influencing BMI in elementary school children from southern Taiwan is crucial. This study investigated the influencing factors including physical activity levels, sedentary behaviors, dietary habits, and perceived body shape on the BMIs of elementary school children from southern Taiwan. A cross-sectional design was used, and the participants consisted of 3251 fifth-grade students (1628 boys, 50.1%; 1623 girls, 49.9%. The average BMI values for boys and girls were 19.69 and 18.70 (kg/cm respectively. Statistically significant associations were observed between BMI and sex, 31–60 min of daily vigorous or moderate physical activities levels, length of time spent watching television, time spent on video games or the computer, and intake of vegetable or meat gravy with rice (p < 0.001. Perceived body shape also affected the BMI of school children. The results of this study enable educational institutions in Taiwan to understand the factors affecting the BMI of school children and use this information as the basis for future healthy body weight policies.

    Full Text Available Intercultural communication is applied for communicating with each other among the different cultures and traditions. It highlighted the problems which faced by different communities and organizations, the problems which are natural to the person like when the people face to new culture or tradition even the religious issues. So intercultural communication here is seeking for an answer between the different nations that how they communicate with each other when they face some problems in their tradition and culture. This one highlights how the people encode a message and how they interpret a message to each other.  So here in this paper interaction is between students of Arabs and Malays from National University of Malaysia and it deals with their body language especially hand gestures. This paper is based on the Micheal Byram theory of language. In this quantitative research some questions will distribute among the students and the similarities and differences between their sign languages will be highlighted.

    This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32). The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively). The tests were applied (two-factor ANOVA) to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104) and self-esteem (p=0.09) were considered significant. The results demonstrated that age negatively correlated with body dissatisfaction (r=-0.19; pbody mass index levels were associated with greater body dissatisfaction (r=0.15, p=0.016) and lower levels of self-esteem (r=-0.17, pbody dissatisfaction (F=4.79; p=0.030; η(2)=0.02), but there was no significant difference in self-esteem (F=1.88; p=0.172; η(2)=0.02). It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the non-practitioners group.

    Full Text Available Much research suggests that educational process, learning and students' performance depend on a number of factors such as personal and professional characteristics of teachers, curricula, and the quality of teaching and extra-curricular activities. In addition, the quality of educational process is closely connected to material-technical conditions of the school and the quality of teaching equipment. This mostly concerns school facilities (school buildings, classrooms, cabinets, library, other facilities, courtyard and gymnasium, equipment, furniture and teaching aids. However, quality learning and work also require favourable physical, physiological, social and psychological conditions for study. This is the reason why this paper investigates students' opinions concerning the influence of certain characteristics of school facilities (wall colours, visual aids hanging on walls, teaching aids, furniture, and other physical aspects, including the size of student's groups on the quality of study and learning, as well as whether these opinions vary according to sex, age and year of study. The data was collected by a questionnaire comprising 25 items especially designed for the needs of this investigation. There were 116 respondents, students of the Preschool Teacher Training College in Kruševac. The findings show that certain features of the space and certain physical characteristics do have impact on students' work and performance, and therefore on the quality of teaching. They also demonstrate that students' estimates and opinions vary according to age and year of study.

    Full Text Available Poor dietary habits have become one of the most important concerns among public health policy makers in recent years, due to the impact they have on both economic and health systems of a country. The transitional period toward young adulthood, marked with high school graduation and the beginning of college years, has been identified as critical in terms of its influence on young people’s bad eating habits. The aim of this study was to assess whether the results obtained through Food Frequency Questionnaire significantly correlate with standard body parameters. Participants included 210 students from the University of Banja Luka, with the mean age of 21.94 ± 2.73 years. Factorization of Food Frequency Questionnaire Instrument extracted seven factors which were subjected to multiple regression analysis as independent variables, and correlated to dependent variables - anthropological measurements. This study shows that the factors labeled as consumption of bread, consumption of healthy food, and intake of carbohydrates, are significantly related to Body Fat Percentage, whereas factors labeled as intake of food of animal origin, and intake of fruits and vegetables, are statistically significant in terms of their relation to Waist-to-Hip Ratio. Only one factor, labeled as intake of unhealthy food, is significantly related to Body Mass Index; this is to suggest that Body Mass Index has again showed many limitations with regard to its research relevance. This research has also found that students of the University of Banja Luka typically consume white bread, known to have a direct link with overweight and obesity.

    This study aimed to examine the association between body mass index (BMI) and school performance in high school students by controlling for relevant mediators such as sleep quality, sleep duration and socioeconomic status. Thirty-seven high school students (mean age: 18.16 ± 0.44 years) attending the same school type, i.e. 'liceo scientifico' (science-based high school), were enrolled. Students' self-reported weight and height were used to calculate BMI. Participants wore an actigraph to objectively assess the quality and duration of sleep. School performance was assessed through the actual grade obtained at the final school-leaving exam, in which higher grades indicate higher performance. BMI, get-up time, mean motor activity, wake after sleep onset and number of awakenings were negatively correlated with the grade, while sleep efficiency was positively correlated. When performing a multiple regression analysis, BMI proved the only significant (negative) predictor of grade. When controlling for sleep quality, sleep duration and socioeconomic status, a higher BMI is associated with a poorer school performance in high school students. © 2015 World Obesity Federation.

    Taiwan has good support systems for obesity prevention and management. The percentage of elementary school students with normal body weight, however, has undergone a sustained decrease to 55%. Many factors are associated with this trend, such as lack of physical activity, dissatisfaction with body image, unbalanced dietary pattern, and unsupportive environment. Even though the rate of overweight and obesity is under control, the rate of underweight among girls has undergone a sustained increase, to 28%. Nurses therefore organized the "Aid students to fit" project, which emphasizes the bipolar issue of overweight and underweight. This national project is sponsored by the Ministry of Education and is expected to establish a beneficial environment, in which students can easily adopt healthy lifestyles and increase self-esteem. The program incorporates the AID triangle concept (Active, Image, Diet) and five strategies for achieving the goals. These strategies are: 1. Develop a persuasive statement to fit in with the philosophies of parents, students and teachers. 2. Set up measurable behavior indices and slogans. (Active life: 210 minutes per week. Image: confident and elegant. Diet: balanced and wise choice of low fat and high fiber foods.) 3. Establish a nation-wide interactive surveillance system for body weight control. 4. Develop an internet system that emphasizes tailored case management for overweight students. 5. Develop a supportive teaching plan, material, and aids to promote a healthy school environment. Five modeling schools, moreover, can be used to demonstrate the program. Educators can also download a free teaching plan, material, and aids at the website for healthy weight management (www.ym.edu.tw/active/aid). The authors brought together scholars from eight universities to accomplish the program. In support of the program, the Taiwan Ministry of Education addressed the new recommendation for physical activity which is to engage in moderate intensity

    This longitudinal study examined relationships between student-perceived teaching for meaning, support for autonomy, and competence in mathematic classrooms (Time 1), and students' achievement goal orientations and engagement in mathematics 6 months later (Time 2). We tested whether student-perceived instructional characteristics at Time 1 indirectly related to student engagement at Time 2, via their achievement goal orientations (Time 2), and, whether student gender moderated these relationships. Participants were ninth and tenth graders (55.2% girls) from 46 classrooms in ten secondary schools in Berlin, Germany. Only data from students who participated at both timepoints were included (N = 746 out of total at Time 1 1118; dropout 33.27%). Longitudinal structural equation modeling showed that student-perceived teaching for meaning and support for competence indirectly predicted intrinsic motivation and effort, via students' mastery goal orientation. These paths were equivalent for girls and boys. The findings are significant for mathematics education, in identifying motivational processes that partly explain the relationships between student-perceived teaching for meaning and competence support and intrinsic motivation and effort in mathematics.

    Modeling of multibody dynamics with flexible links is a challenging task, which not only involves the effect of rigid body motion on elastic deformations, but also includes the influence of elastic deformations on rigid body motion. This paper presents coupling characteristics of rigid body motions and elastic motions of a 3-PRR parallel manipulator with three flexible intermediate links. The intermediate links are modeled as Euler-Bernoulli beams with pinned-pinned boundary conditions based on the assumed mode method (AMM). Using Lagrange multipliers, the fully coupled equations of motions of the flexible parallel manipulator are developed by incorporating the rigid body motions with elastic motions. The mutual dependence of elastic deformations and rigid body motions are investigated from the analysis of the derived equations of motion. Open-loop simulation without joint motion controls and closed-loop simulation with joint motion controls are performed to illustrate the effect of elastic motion on rigid body motions and the coupling effect amongst flexible links. These analyses and results provide valuable insight to the design and control of the parallel manipulator with flexible intermediate links

    Full Text Available Entrepreneurship can be defined as a capability that realizes the opportunities created by environment paradigms and that transforms these opportunities into projects, and that live these projects and transfer all these as well as produce richness. In this process, there are a great many characteristics for successful entrepreneurs. In addition, the spirit of entrepreneurship can be available as a genetic code, families, jobs, environments as well as education which can be regarded as a significant component for the development of entrepreneurship spirit. In this study, the main objective is to analyze the relationship between entrepreneurship personality characteristics and entrepreneurship inclinations of the students in the department of Business Management. Therefore, a questionnaire was conducted on the students in the department of Business Management to test the hypothesis revealed. As a result of the study, it was determined that innovation, sensitivity, and opportunism are the pioneers of the entrepreneurship characteristics for the students while struggling against stress is the least level of characteristic for entrepreneurship. At the same time, in the study, the relationship was found out between entrepreneurship characteristics and gender, and also between participants’ family occupations and their entrepreneurship characteristics.

    2014-01-01

    This study explored whether anthropometric measures influence magnitude of skin cooling following exposure to whole body cryotherapy (WBC). Height, weight, body fat percentage, and lean mass were measured in 18 male and 14 female participants. Body surface area, body surface area to mass ratio, body mass index, fat-free mass index, and fat mass index were calculated. Thermal images were captured before and after WBC (−60°C for 30 seconds, −110°C for 2 minutes). Skin temperature was measured at the chest, arm, thigh, and calf. Mean skin temperature before and after WBC and change in mean skin temperature (ΔT sk) were calculated. ΔT sk was significantly greater in females (12.07 ± 1.55°C) than males (10.12 ± 1.86°C; t(30) = −3.09, P = .004). A significant relationship was observed between body fat percentage and ΔT sk in the combined dataset (P = .002, r = .516) and between fat-free mass index and ΔT sk in males (P = .005, r = .622). No other significant associations were found. Skin response of individuals to WBC appears to depend upon anthropometric variables and sex, with individuals with a higher adiposity cooling more than thinner individuals. Effects of sex and anthompometrics should be considered when designing WBC research or treatment protocols. PMID:25061612

    Early adulthood is related to changes in lifestyle that negatively affect body weight and health. The aim of the study was to determine the effect of exercise changes on the development of weight and body composition in college students.Sixty-one randomly selected dental (ZMS) and 53 sport students (SLS) were accompanied over 5 years. Body mass, fat and lean body mass (LBM) were determined via DXA-technique. Exercise and physical activity were assessed by questionnaires and interviews.All exercise indices significantly increased in the SLS and significantly decreased in the ZMS. Physical activity slightly increased in both groups. Both cohorts comparably gained body mass, however, the increase in the SLS group can be attributed to LBM-changes with minor changes of fat-mass (2.4 % ± 3.3 % vs. 0.1 ± 1.0 %) whereas ZMS gained fat and LBM in a proportion of 2:1.Maintenance/increase of exercise compensate the negative effects of lifestyle changes on body composition during young adulthood.

    The characteristic whole-body and pinhole scintigraphic manifestations of osteo-enthesopathy and arthropathy in Reiter`s syndrome (RS) are described, with an emphasis on early diagnosis. We analysed 59 sets of whole-body and pinhole bone scintigrams of 59 patients with RS. The population comprised 47 men and 12 women with an age range from 15 to 53 years (mean=29.4). Bone scintigraphy was carried out 2-2.5 h after intravenous injection of technetium-99m hydroxydiphosphonate using a single-head gamma camera (Siemens Orbiter Model 6601) with a low-energy high-resolution and a 4-mm pinhole collimator for whole-body and pinhole scintigraphy, respectively. In total 262 lesions of osteo-enthesopathy and arthritis were detected on 59 whole-body scintigrams, an incidence of 4.4 lesions per patient. As anticipated, the lesional distribution was asymmetrical: 68% were in the lower limb skeleton and 32% in the axial and upper limb skeleton. Pinhole bone scintigraphy, applied selectively to one region of interest in each case, enabled us to accurately diagnose arthritis and osteo-enthesopathy. It was noteworthy that osteo-enthesopathy, alone or in combination with arthritis, occurred in 78.9%, and had a strong predilection for the foot bones, especially the calcaneus (25.6%). Pinhole scintigraphy detected enthesopathy in the absence of radiographic alteration in 14.1% of cases and portrayed characteristic signs of RS in 6.9%. Whole-body bone scintigraphy augmented with pinhole scintigraphy was found to be useful in order to panoramically display the systemic involvement pattern, to assess the characteristic bone and articular alterations and to detect early signs of RS.

    Bluff-body flame stabilization has been used as one of main flame stabilization schemes to improve combustion stability in both large and small scale premixed combustion systems. The detailed investigation of instability characteristics is needed to understand flame stability mechanism. Direct numerical simulations are conducted to investigate flame dynamics on the instability of lean premixed hydrogen/air and syngas/air flames stabilized on a meso-scale bluff-body. A two-dimensional channel of 10 mm height and 10 mm length with a square bluff-body stabilizer of 0.5 mm is considered. The height of domain is chosen as an unconfined condition to minimize the effect of the blockage ratio. Flame/flow dynamics are observed by increasing the mean inflow velocity from a steady stable to unsteady asymmetrical instability, followed by blowoff. Detailed observations between hydrogen and syngas flames with a time scale analysis are presented.

    Full Text Available BACKGROUND Early sleep, early waking up, regular breakfast and light-to-moderate exercise all constitute healthy habits. Balanced diet, regular sleep and adequate physical activity are major factors in the promotion and maintenance of good health in human life. Regrettably these habits are not very frequent among medical students, because of exceptionally tiring schedule, protracted studies and burden of performing well in medical colleges. The study aims to correlate the trends in breakfast habits, mid-day snacking, sleeping habits and physical activity in relation to body mass index among medical students. METHOD This was a single centre cross-sectional questionnaire based study conducted at Jubilee Mission Medical College & Research Institute, Thrissur, Kerala. The target population was 1 st year MBBS students. We collected data from 234 students. The study duration was from August 2014 till September 2015. Convenient sampling was implied for the collection of data. RESULTS Mean age of participants was 20.85 ± 0.9 years, while mean BMI of participants was 24.7 ± 6.31 kg/m2. Average sleep duration was 7.1 hours ± 3.9 hours while average physical activity was 208 min/week ± 92 min/week. We observed that females (63.4% tend to skip breakfast twice more than males (27.9%. Students who had regular breakfast were found to have a lower BMI than those who did not. Moreover, those who took breakfast were found to be more physically active than those who skipped breakfast. CONCLUSION Since it was found that a regular consumption of breakfast, adequate sleep and exercise not only lowers BMI but also makes a person more physically fit. Therefore, it is recommended to start the day with a healthy breakfast having all the essential nutrients.

    Full Text Available The nutritional needs increase in puberty due to rapid growth and changes in body composition. Because of that healthy eating is vital for teen’s health. The aim of this study was to determine eating habits and weight control behaviors of high school students. A cross-sectional study was performed involving all (6 public and 3 private tenth-grade high schools in Manisa city. Two thousand one hundred forty six students completed a questionnaire which consists of 26 items and was designed by researchers. Among all students surveyed, 34.0% reported that they don’t have a habit to eat breakfast regularly, 38.3% reported that they don’t have a habit to eat lunch regularly, 6.5% reported that they don’t have a habit to eat dinner regularly, 36.7% reported that they were afraid getting fat, 6.5% reported that they were dieting, 39.4% reported that they don’t make sport regularly and 59.1% reported that they were snacking frequently. In this study it has seen that skipping meals is a common eating habit in high school students and many of them fail to eat three regular meals per day. On the other hand it has seen that students don’t have regular exercise habits. The results of this study have suggested that there is a need to encourage teens a healthy lifestyle that incorporates eating habits and regular exercise. [TAF Prev Med Bull. 2007; 6(2: 98-105

  1. Aspects of science engagement, student background, and school characteristics: Impacts on science achievement of U.S. students

    Science.gov (United States)

    Grabau, Larry J.

    Science achievement of U.S. students has lagged significantly behind other nations; educational reformers have suggested science engagement may enhance this critical measure. The 2006 Program for International Student Assessment (PISA) was science-focused and measured science achievement along with nine aspects of science engagement: science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities. I used multilevel modeling techniques to address both aspects of science engagement and science achievement as outcome variables in the context of student background and school characteristics. Treating aspects of science engagement as outcome variables provided tests for approaches for their enhancement; meanwhile, treating science achievement as the outcome variable provided tests for the influence of the aspects of science engagement on science achievement under appropriate controls. When aspects of science engagement were treated as outcome variables, gender and father's SES had frequent (significant) influences, as did science teaching strategies which focused on applications or models and hands-on activities over-and-above influences of student background and other school characteristics. When science achievement was treated as the outcome variable, each aspect of science engagement was significant, and eight had medium or large effect sizes (future-oriented science motivation was the exception). The science teaching strategy which involved hands-on activities frequently enhanced science achievement over-and-above influences of student background and other school characteristics. Policy recommendations for U.S. science educators included enhancing eight aspects of science engagement and implementing two specific science teaching strategies (focus on applications or models

    Full Text Available Purpose: to find correlations between characteristics of body posture in the sagittal plane and fitness and endurance of first-form children from rural areas. Material: an analysis of more than 30 sources of scientific and educational literature. Results: the study involved 209 children, including 102 girls and 107 boys. They were children who lived in the country since they were born. To assess particular characteristics of body posture, the children were studied by means of the measuring equipment using the projection Moiré system. Motor skills were estimated using selected EUROFIT physical fitness tests (sitting forward bend, standing broad jump, handgrip, sit-and-reach, bent arm hang and 10 x 5 m shuttle run. The level of physical endurance was evaluated with the Harvard Step Test modified by Montoye. Conclusions: the conducted research reveals statistically significant correlations between the characteristics of body posture in the sagittal plane and selected EUROFIT physical fitness tests and physical endurance of the children involved in the study.

    This study investigated the clinical characteristics of internet addiction using a cross-sectional survey and psychiatric interview. A structured questionnaire consisted of demographics, Symptom Checklist 90, Self-Rating Anxiety Scale, Self-Rating Depression Scale, and Young's Internet Addiction Test (YIAT) was administered to students of two secondary schools in Wuhan, China. Students with a score of 5 or higher on the YIAT were classified as having Internet Addiction Disorder (IAD). Two psychiatrists interviewed students with IAD to confirm the diagnosis and evaluate their clinical characteristics. Of a total of 1076 respondents (mean age 15.4 ± 1.7 years; 54.1% boys), 12.6% (n = 136) met the YIAT criteria for IAD. Clinical interviews ascertained the Internet addiction of 136 pupils and also identified 20 students (14.7% of IAD group) with comorbid psychiatric disorders. Results from multinomial logistic regression indicated that being male, in grade 7-9, poor relationship between parents and higher self-reported depression scores were significantly associated with the diagnosis of IAD. These results advance our understanding of the clinical characteristics of Internet addiction in Chinese secondary school students and may help clinicians, teachers, and other stakeholders better manage this increasingly serious mental condition. © 2014 The Authors.

  11. Body motion and physics: How elementary school students use gesture and action to make sense of the physical world

    Science.gov (United States)

    Noble, Tracy

    This study is an exploration of the role of physical activity in making sense of the physical world. Recent work on embodied cognition has helped to break down the barrier between the body and cognition, providing the inspiration for this work. In this study, I asked ten elementary-school students to explain to me how a toy parachute works. The methods used were adapted from those used to study the role of the body in cognition in science education, child development, and psychology. This study focused on the processes of learning rather than on measuring learning outcomes. Multiple levels of analysis were pursued in a mixed-method research design. The first level was individual analyses of two students' utterances and body motions. These analyses provided initial hypotheses about the interaction of speech and body motion in students' developing understandings. The second level was group analyses of all ten students' data, in search of patterns and relationships between body motion and speech production across all the student-participants. Finally, a third level of analysis was used to explore all cases in which students produced analogies while they discussed how the parachute works. The multiple levels of analysis used in this study allowed for raising and answering some questions, and allowed for the characterization of both individual differences and group commonalities. The findings of this study show that there are several significant patterns of interaction between body motion and speech that demonstrate a role for the body in cognition. The use of sensory feedback from physical interactions with objects to create new explanations, and the use of interactions with objects to create blended spaces to support the construction of analogies are two of these patterns. Future work is needed to determine the generalizability of these patterns to other individuals and other learning contexts. However, the existence of these patterns lends concrete support to the

    Full Text Available The aim of this study was to examine intensity of motor and intellectual abilities and motivation for physical activity of students engaged in physical education in different sports groups.Methodology and research methods. Motor abilities of the students were assessed by measuring: hand, strength endurance, speed-power abilities, speed ability and general stamina. Assessment of general intelligence (GI was carried out by R. Amthauer’s test in the adaptation of L. A. Yasjukova. Formal-dynamic characteristics of the individuality (FDCI were studied using the technique of FDCI feedback form proposed by V. M. Rusalov. Assessment of motivation to implement motor activity was performed using the author's questionnaire. The method of statistical information processing has allowed the author to reveal correlation communications between motor abilities and GI of first-year students.Results. Significant differences in the manifestation of the individual students’ characteristics choosing practicing in different types of physical activity are experimentally established. In particular, students who chose table tennis, are inferior to the students who went in for wrestling in the manifestation of certain (power, motor skills, motivation for physical activity, but at the same time show relatively higher rates of certain intellectual abilities.Formal-dynamic traits of individuality are peculiar to students involved in table tennis, reflecting lower psychomotor activity (integrated indicator PDI - Psychomotor Development Index, in comparison with students who prefer fighting. The material presented provides a basis to argue that sports-oriented approach has some potential in the aspect of increase of efficiency of students’ physical education, distinguished by individual characteristics of age specific development.Scientific novelty.

    This study was conducted to examine how subjects modulate their food intake and energy balance when they migrate from a low energy density food intake pattern to one of high energy density. It was hypothesised that an increase in the energy density of food consumed would result in increased body weight of the migrating subjects unless food intake and energy balance could be modulated. Food selection, food intake, basal metabolic rate (BMR) and anthropometric measurements were made on 53 female and 56 male newly arrived overseas students. All subjects were from Malaysia, but the data was collected at Oxford Brookes University where the subjects were studying. Food intake using 3-day food diaries and food frequency questionnaires (FFQs). BMR and anthropometric measurements including body weight were measured on arrival in the UK and after 3 and 6 months' stay. Student's t-tests and analysis of variance (ANOVA) were used to compare the data. A significant difference (P foods consumed in Malaysia and after 3 and 6 months in the UK. There was also a significant decrease (P food selection due mainly to the lack of availability of certain foods in UK supermarkets. No significant differences were found in the BMR and anthropometric measurements made at the start of the study and later assessments. It appears that Malaysian students are able to remain in energy balance and are weight stable at least during the first 6 months of residence in the UK, despite the wider choice of energy dense food available. This suggests that at least in the short term, subjects are able to modulate their food intake in response to changes in the energy densities and free choice of food.

    Full Text Available Abstract Background Living in a world greatly controlled by mass media makes it impossible to escape its pervading influence. As media in Pakistan has been free in the true sense of the word for only a few years, its impact on individuals is yet to be assessed. Our study aims to be the first to look at the effect media has on the body image of university students in a conservative, developing country like Pakistan. Also, we introduced the novel concept of body image dissatisfaction as being both negative and positive. Methods A cross-sectional study was conducted among 7 private universities over a period of two weeks in the city of Karachi, Pakistan's largest and most populous city. Convenience sampling was used to select both male and female undergraduate students aged between 18 and 25 and a sample size of 783 was calculated. Results Of the 784 final respondents, 376 (48% were males and 408 (52% females. The mean age of males was 20.77 (+/- 1.85 years and females was 20.38 (+/- 1.63 years. Out of these, 358 (45.6% respondents had a positive BID (body image dissatisfaction score while 426 (54.4% had a negative BID score. Of the respondents who had positive BID scores, 93 (24.7% were male and 265 (65.0% were female. Of the respondents with a negative BID score, 283 (75.3% were male and 143 (35.0% were female. The results for BID vs. media exposure were similar in both high and low peer pressure groups. Low media exposure meant positive BID scores and vice versa in both groups (p Conclusions Our study confirmed the tendency of the media to have an overall negative effect on individuals' body image. A striking feature of our study, however, was the finding that negative body image dissatisfaction was found to be more prevalent in males as compared to females. Likewise, positive BID scores were more prevalent amongst females.

    Objectives Autoantibodies directed against cytosolic 5′-nucleotidase 1A have been identified in many patients with inclusion body myositis. This retrospective study investigated the association between anticytosolic 5′-nucleotidase 1A antibody status and clinical, serological and histopathological features to explore the utility of this antibody to identify inclusion body myositis subgroups and to predict prognosis. Materials and methods Data from various European inclusion body myositis registries were pooled. Anticytosolic 5′-nucleotidase 1A status was determined by an established ELISA technique. Cases were stratified according to antibody status and comparisons made. Survival and mobility aid requirement analyses were performed using Kaplan-Meier curves and Cox proportional hazards regression. Results Data from 311 patients were available for analysis; 102 (33%) had anticytosolic 5′-nucleotidase 1A antibodies. Antibody-positive patients had a higher adjusted mortality risk (HR 1.89, 95% CI 1.11 to 3.21, p=0.019), lower frequency of proximal upper limb weakness at disease onset (8% vs 23%, adjusted OR 0.29, 95% CI 0.12 to 0.68, p=0.005) and an increased prevalence of excess of cytochrome oxidase deficient fibres on muscle biopsy analysis (87% vs 72%, adjusted OR 2.80, 95% CI 1.17 to 6.66, p=0.020), compared with antibody-negative patients. Interpretation Differences were observed in clinical and histopathological features between anticytosolic 5′-nucleotidase 1A antibody positive and negative patients with inclusion body myositis, and antibody-positive patients had a higher adjusted mortality risk. Stratification of inclusion body myositis by anticytosolic 5′-nucleotidase 1A antibody status may be useful, potentially highlighting a distinct inclusion body myositis subtype with a more severe phenotype.

    Full Text Available We describe a study of career representations in school and university students in relation to gender characteristics. The sample consisted of 36 students of XI grade and 40 students of I year of high school. We tested the hypothesis about relationship of career representations with gen-der characteristics of the subjects and their stage of professional development. The methods we used were “career anchors” by E. Schein, “Psychological gender” by S. Bem, survey “Professional career ideals" by A.M. Sheveleva. The statistical significance level of results was 0.05. It was re-vealed that, despite both school pupils and students preferred achievements, wealth and social recognition as the content of the ideal career, there are differences between the samples. Pupils are more focused on the “General managerial competence” and “Security/stability”, the students –on “Service/dedication to a cause” and “Technical/functional competence”. Regardless of sex, school pupils with an increase of masculinity have enhanced value of ”Pure challenge” orienta-tion and lowered value of the “Mode of Life” ideal career. The female students with increased femininity have higher importance of such content ideal career as “Experience Acquisition” and “Professional Path”, the value of career orientation “Autonomy/independence” is increased.

    Full Text Available This study assessed the feasibility of stochastic resonance whole-body vibration (SR-WBV training and its impact on isometric maximal voluntary contraction (IMVC, isometric rate of force development (IRFD and a drop jump test (DJ in healthy female students. Twelve participants were randomised to static squats during SR-WBV 6 Hz, noise level 4, over 4 weeks or to a control group (no training. Feasibility outcomes included the number of students agreeing to participate, the number of drop-outs, the adherence to the SR-WBV and the evaluation of the protocol. Secondary outcomes were IMVC, IRFD and DJ. Results: Among 35 eligible students, 12 agreed to participate and two dropped out. The adherence was 41 of 60 possible sessions. There were moderate to large, but statistically non-significant, gains in the secondary outcomes. Conclusion: These results suggest that such a study would be feasible although with some modifications such as a better familiarisation to the DJ.

    2018-01-01

    The aim of this article is to investigate students' meaning-making processes of multiple representations during a teaching sequence about the human body in lower secondary school. Two main influences are brought together to accomplish the analysis: on the one hand, theories on signs and representations as scaffoldings for learning and, on the other hand, pragmatist theories on how continuity between the purposes of different inquiry activities can be sustained. Data consist of 10 videotaped and transcribed lessons with 14-year-old students (N = 26) in Sweden. The analysis focused instances where meaning of representations was negotiated. Findings indicate that continuity is established in multiple ways, for example, as the use of metaphors articulated as an interlanguage expression that enables the students (and the teacher) to maintain the conversation and explain pressing issues in ways that support of the end-in-view of the immediate action. Continuity is also established between every day and scientific registers and between organisation levels as well as between the smaller parts and the whole system.

    Full Text Available The goal of this study was to explore the predictive validity of physical self-efficacy, social physique anxiety, and physical activity in the self-esteem of students, as well as to investigate potential gender differences. The Rosenberg's Self-Esteem Scale (SES, Physical Self-Efficacy Scale (PSES, Social Physique Anxiety Scale (SPAS, and a short questionnaire about physical activity were administered to a sample of 232 university students. The overall results show that students are moderately physically active (on the average, 2.75 times per week, have moderately high selfesteem and physical self-efficacy and lower social physique anxiety. No gender differences were detected in self-esteem. In other variables, gender differences are significant and mostly in favour of males. The analyses showed that self-esteem correlated positively with physical self-efficacy and physical activity, and negatively with social physique anxiety. The regression analyses indicated that physical selfefficacy, social physique anxiety and female gender were significant predictors of self-esteem. Physical activity was not a significant predictor of self-esteem. Future studies should investigate the relations of body self-perceptions, physical exercise, and domain-specific self-esteem.

    It is recognized that there is a high esthetic demand in ballet, and this has implications on dancers' body mass index (BMI) and eating behaviors. The objective of this study was to examine the association between BMI, eating attitudes, and nutritional knowledge of elite student and professional ballet dancers. Observational design. Institutional. One hundred eighty-nine participants from an elite full-time dance school (M = 53, F = 86) and from an elite ballet company (M = 16, F = 25) volunteered for the study. There were no exclusion criteria. Anthropometric data (height and mass), General Nutrition Knowledge Questionnaire (GNKQ), and the Eating Attitude Test-26 (EAT-26) were collected from each participant. Univariate analysis of variance was used to examine differences in gender and group for BMI, GNKQ, and EAT-26. Regression analyses were applied to examine interactions between BMI, GNKQ, and EAT-26. Professional dancers had significantly greater BMI than student dancers (P < 0.001), and males had significantly higher BMI scores than females (P < 0.05). Food knowledge increased with age (P < 0.001) with no gender difference. Student dancers had a significant interaction between year group and gender because of significantly higher EAT-26 scores for females in years 10 and 12. Regression analysis of the subcategories (gender and group) reported a number of significant relationships between BMI, GNKQ, and EAT-26. The findings suggest that dancers with disordered eating also display lower levels of nutritional knowledge, and this may have an impact on BMI. Female students' eating attitudes and BMI should especially be monitored during periods of adolescent development.

    Full Text Available Introduction:The research has been conducted in order to establish differences in motoric abilities due to the body mass index (BMI with the tested students at the eighth grade (Barlow, & the Expert Committee, 2007. Methods: During the research 160 male students aged 14 were tested. On the base of (BMI they were divided into 3 groups (normal, overweight, and with obesity. They were tested with 6 motor tests for: explosive power, repetitive power, coordination, equilibrium, precision, and flexibility. Along with basic statistic parameters, the differences between the groups are established through: ANOVA, MANOVA and LSD-tests. Results: The obtained results are presented in 5 tables. On the base of the results, a statistically significant difference in favor of the group of normal body mass index is recorded in the following tests: standing a long jump, agility on the ground and keeping balance on one leg. Discussion: The results obtained in this research indicate that obesity and overweight cause a negative effect and result in lower performances concerning some motoric abilities. On the base of the obtained results, it is concluded that the group of students of normal body mass index achieved the best results in the motoric abilities with assessing the following: explosive power, coordination, and equilibrium. As for the motoric ability concerning: precision, repetitive power, and flexibility, there are no established statistically significant differences between the three groups. The obtained results correspond with some former researches (Milanese, et al., 2010; Zhu, Sheng, Wu, & Cairney, 2010, and some do not (De Toia, et al., 2009. References: Barlow SE et al. (2007.

    We introduced laparoscopic simulator training for medical students in 2007. This study was designed to identify factors that predict the laparoscopic skill of medical students, to identify intergenerational differences in abilities, and to estimate the variability of results in each training group. Our ultimate goal was to determine the optimal educational program for teaching laparoscopic surgery to medical students. Between 2007 and 2015, a total of 270 fifth-year medical students were enrolled in this observational study. Before training, the participants were asked questions about their interest in laparoscopic surgery, experience with playing video games, confidence about driving, and manual dexterity. After the training, aspects of their competence (execution time, instrument path length, and economy of instrument movement) were assessed. Multiple regression analysis identified significant effects of manual dexterity, gender, and confidence about driving on the results of the training. The training results have significantly improved over recent years. The variability among the results in each training group was relatively small. We identified the characteristics of medical students with excellent laparoscopic skills. We observed educational benefits from interactions between medical students within each training group. Our study suggests that selection and grouping are important to the success of modern programs designed to train medical students in laparoscopic surgery.

    In the practice of orthopedic and trauma surgeons, there is a need to close bone tissue defects after removal of tumors or traumatic and dystrophic lesions. Currently, as cellular technologies are being developed, stem embryonic and pluripotent cells are widely introduced into practical medicine. The unpredictability of the spectrum of cell differentiations, up to oncogenesis, raised the question of creating biological structures committed toward osteogenic direction, capable of regenerating organo-specific graft at the optimal time. Such osteograft was created at the Novosibirsk Institute of Traumatology and Orthopaedics (patent RU 2574942). Its osteogenic orientation was confirmed by the morphological and immunohistochemical methods, and by the expression of bone genes. The regeneration potential of the osteograft was studied in the vertebral bodies of the mini piglet model. The study revealed that the regeneration of the vertebral body defect and the integration of the osteograft with the bed of the recipient proceeds according to the type of primary angiogenic osteogenesis within 30 days.

    2017-12-01

    Full Text Available In a longitudinal study, we determine the beliefs of primary education students regarding the factors of academic achievement, good teachers, and the developmental characteristics of children, and we present which experiences mostly shape these beliefs. The same group of students (N = 59 completed the same questionnaire at the beginning of their first year and then at the end of their postgraduate studies. At both measurements, the students stated that the pupils themselves are the most responsible for their academic achievement (approximately 33%. At the beginning of the study, the students mostly showed idealised beliefs regarding what makes a good teacher, such as he/she is self-controlled and calm in all situations; he/she likes all children equally, etc. At the end, the results showed a reshaping of most idealised beliefs about what makes good teachers towards more realistic ones. Regarding the developmental characteristics of children, at the beginning and at the end of their studies the students had similar beliefs that heredity and environment contribute to an individual’s development. At the end of their studies, the students are significantly less convinced that experience from an early age decisively influences their further development, that there are no major differences in cognitive abilities of pupils of the same class, that a child who knows a lot of information is clever, and that school is not a place for the expression of emotions. According to the students, direct experiences in the classroom have the most significant influence on the beliefs among all the factors that we have examined in the study.

    The aim of this study is to model the computational model of seated whole human body including skeleton, muscle, viscera, ligament, intervertebral disc, and skin to predict effect of the factors (sitting postures, muscle and skin, buttocks, viscera, arms, gravity, and boundary conditions) on the biodynamic characteristics of spine. Two finite element models of seated whole body and a large number of finite element models of different ligamentous motion segments were developed and validated. Static, modal, and transient dynamic analyses were performed. The predicted vertical resonant frequency of seated body model was in the range of vertical natural frequency of 4 to 7 Hz. Muscle, buttocks, viscera, and the boundary conditions of buttocks have influence on the vertical resonant frequency of spine. Muscle played a very important role in biodynamic response of spine. Compared with the vertical posture, the posture of lean forward or backward led to an increase in stress on anterior or lateral posterior of lumbar intervertebral discs. This indicated that keeping correct posture could reduce the injury of vibration on lumbar intervertebral disc under whole-body vibration. The driving posture not only reduced the load of spine but also increased the resonant frequency of spine. Copyright © 2017 John Wiley & Sons, Ltd.

    Obesity and its comorbidities have emerged as a leading public health concern. The aim of this study was to explore the relationship between body mass index (BMI) and sleep patterns, including duration and disturbances. A convenience sample of 515 college students completed an online survey consisting of the Pittsburgh Sleep Quality Index (PSQI), and self-reported height and weight to calculate BMI. Univariate and multivariate logistic regression analyses were performed using components of the PSQI as predictors of overweight (BMI ≥ 25). One-third of the participants had BMI ≥ 25, and 51% were poor-quality sleepers (PSQI > 5). Controlling for age and sex, only sleep disturbances were associated with overweight (odds ratio = 1.66, 95% confidence interval [1.08, 2.57]). Sleep disturbances, rather than sleep duration, predicted overweight among young adults; this is consistent with the most recent evidence in the literature. These findings support expanding the scope of wellness programs to promote healthy sleep among students.

Materials and Methods: Mind, body and spirit survey instruments administered to the two groups. Results: Five indicators to measure mental wellness were significantly different between yoga practitioners and college students. On three of these five measures, college students reported more mental wellness than yoga practitioners - in other words, the relationship was the inverse of what was expected. College students reported maintaining stability in their life more often than yoga practitioners as well as more often experiencing satisfying interpersonal relationships. College students were also more likely than yoga practitioners to report being tolerant of others, whether or not they approved of their behavior or beliefs. Yoga practitioners were more likely than college students to report having strong morals and healthy values as well as the ability to express their feelings and consider the feelings of others. We found differences between yoga practitioners and college students on more than half of our spirit items (five of nine. Yoga practitioners were more likely than college students to report expressing their spirituality appropriately and in healthy ways, recognizing the positive contribution faith could make to the quality of life (significant at the 0.07 level, routinely undertaking new experiences to enhance spiritual health and having a positive outlook on life. Further, we found support for the proposition that yoga practitioners were more likely to report experiencing happiness within. Conclusions: Significant differences between yoga and college students were found on the body, mind and spirit measurement instrument. Further work needs to address the complexities of these relationships.

    Background The new phenomenon of Internet addiction among teenagers and young adults is one of the modern addictions in industrial and post-industrial societies. The purpose of this research was to predict the Internet addiction based on the personality characteristics of high school students in Kerman. Methods This research was a descriptive correlational study. The statistical population included 538 male and female students in the second grade of high school in Kerman during 2010. The subjects were randomly selected by multistage clustering. Data was collected by two questionnaires including the five-factor Revised NEO Personality Inventory and the Internet dependency questionnaire. The data was analyzed using ANOVA test and multivariable regression analysis. Findings The findings showed a significant relationship between the personality trait of emotional stability and academic fields, i.e. students with higher emotional stability experience less negative emotions when confronting with problems. Therefore, it is less likely for them to alleviate the negative emotions by the extreme and obsessed usage of the Internet. In addition, it appears that the students with high extroversion scores prefer social, face to face interactions with other people to interaction with the virtual world. Conversely, more introvert students avoid interactions with other people due to their shyness. Thus, they communicate with the virtual world more. Conclusion Three personality traits of loyalty, emotional stability, and extroversion are the most significant predictors of Internet addiction in high school students. PMID:24494121

    This study examines the prevalence and characteristics of services reported by school staff for 543 high school students participating in the 8 year follow-up of the multi-site Multimodal Treatment study of ADHD (MTA). Overall, 51.6% of students with a history of attention-deficit/hyperactivity disorder (ADHD) were receiving services through an Individualized Educational Plan (IEP) or a 504 plan, a rate higher than expected for this age group. Less than 5% of these had 504 plans; 35.5% attended special education classes. Very few services (except tutoring) were provided outside of an IEP or 504 plan. Almost all students with services received some type of academic intervention, whereas only half received any behavioral support or learning strategy. Less than one-fourth of interventions appear to be evidence-based. Students receiving services showed greater academic and behavioral needs than those not receiving services. Services varied based upon type of school, with the greatest number of interventions provided to students attending schools that only serve those with disabilities. Original MTA treatment randomization was unrelated to services, but cumulative stimulant medication and greater severity predicted more service receipt. Results highlight a need for accommodations with greater evidence of efficacy and for increased services for students who develop academic difficulties in high school.

A specific questionnaire, built to that effect, was used to obtain dates. This instrument was validated by different experts on this area of studies, and statistic tests was done to check its reliability (Alpha Cronbach: .78 using SPSS V.15. The main results showed that 62.19% of students do physical activity regularly. Students prefer recreational activities or exercise aimed at being fit or watching health instead competitive games. Activities done by students inside University are very similar to activities done out of this. They also do exercise during all academic year, preferably along the all week or from Monday to Friday, and especially in the afternoon. This group usually practice with friends, classmates or workmates, but lonely too, and they prefer public areas and public or private sport facilities for their sport practice.Key Words: University students, physical activity practice, leisure time.

    The relationships between involvement in sports and alcohol consumption appear to be complex in the alcohol literature. In this study we aimed to examine this link among French students, taking into account their sports characteristics. We also examined variations in alcohol use among sport sciences students between 2002 and 2006, and the difference in alcohol use and heavy episodic drinking among sport sciences, law and pharmacy students. repeated survey; cross-sectional study; self-questionnaire survey; French (south-east France) sport sciences (n=693), law (n=325) and pharmacy (n=338) students (females=58%).

    Chatman, Lawrence M., Jr.

    If the United States is to remain technologically competitive, persistence in engineering programs must improve. This study on student persistence employed a mixed-method design to identify the cognitive and noncognitive factors which contribute to students remaining in an engineering science curriculum or switching from an engineering curriculum at a community college in the northeast United States. Records from 372 students were evaluated to determine the characteristics of two groups: those students that persisted with the engineering curriculum and those that switched from engineering; also, the dropout phenomenon was evaluated. The quantitative portion of the study used a logistic regression analyses on 22 independent variables, while the qualitative portion of the study used group interviews to investigate the noncognitive factors that influenced persisting or switching. The qualitative portion of the study added depth and credibility to the results from the quantitative portion. The study revealed that (1) high grades in first year calculus, physics and chemistry courses, (2) fewer number of semesters enrolled, (3) attendance with full time status, and (4) not participating in an English as a Second Language (ESL) program were significant variables used to predict student persistence. The group interviews confirmed several of these contributing factors. Students that dropped out of college began with (1) the lowest levels of remediation, (2) the lowest grade point averages, and (3) the fewest credits earned.

    The new phenomenon of Internet addiction among teenagers and young adults is one of the modern addictions in industrial and post-industrial societies. The purpose of this research was to predict the Internet addiction based on the personality characteristics of high school students in Kerman. This research was a descriptive correlational study. The statistical population included 538 male and female students in the second grade of high school in Kerman during 2010. The subjects were randomly selected by multistage clustering. Data was collected by two questionnaires including the five-factor Revised NEO Personality Inventory and the Internet dependency questionnaire. The data was analyzed using ANOVA test and multivariable regression analysis. The findings showed a significant relationship between the personality trait of emotional stability and academic fields, i.e. students with higher emotional stability experience less negative emotions when confronting with problems. Therefore, it is less likely for them to alleviate the negative emotions by the extreme and obsessed usage of the Internet. In addition, it appears that the students with high extroversion scores prefer social, face to face interactions with other people to interaction with the virtual world. Conversely, more introvert students avoid interactions with other people due to their shyness. Thus, they communicate with the virtual world more. Three personality traits of loyalty, emotional stability, and extroversion are the most significant predictors of Internet addiction in high school students.

    Full Text Available The purpose of this study was to investigate teachers’ judgments of mathematically gifted students’ characteristics with respect to various variables. Data were collected from primary school teachers and middle school math teachers (N=161 by using a survey instrument. According to research findings most of the teachers tended to think that mathematical giftedness is being observed more frequently within boys than girls. There was a statistically significant relationship between teachers’ responses about whether mathematical giftedness could be developed or not who have mathematically gifted students and those who have not. But there was no statistically significant relationship among teachers’ branch, teaching experience and their answers about the development of mathematical giftedness. Results showed that there was a statistically significant relationship between teachers’ selfperception of being mathematically gifted and their experience with mathematically gifted students. Total scores of more popular and most popular characteristics that were determined by teachers had a positive correlation with teachers’ experience. Key Words:

    The workplace is an important domain for adults, and many effective interventions targeting physical activity and weight reduction have been implemented in the workplace. However, the U.S. workforce is aging, and few studies have examined the relationship of BMI, physical activity, and age as they relate to workplace characteristics. This paper reports on the distribution of physical activity and BMI by age in a population of hospital-based healthcare workers and investigates the relationships among workplace characteristics, physical activity, and BMI. Data from a survey of patient care workers in two large academic hospitals in the Boston area were collected in late 2009 and analyzed in early 2013. In multivariate models, workers reporting greater decision latitude (OR=1.02, 95% CI=1.01, 1.03) and job flexibility (OR=1.05, 95% CI=1.01, 1.10) reported greater physical activity. Overweight and obesity increased with age (pworkplace characteristics. Sleep deficiency (OR=1.56, 95% CI=1.15, 2.12) and workplace harassment (OR=1.62, 95% CI=1.20, 2.18) were also associated with obesity. These findings underscore the persistent impact of the work environment for workers of all ages. Based on these results, programs or policies aimed at improving the work environment, especially decision latitude, job flexibility, and workplace harassment should be included in the design of worksite-based health promotion interventions targeting physical activity or obesity.

    Resistance training interventions aimed at increasing lower-body power and rates of force development have produced varying results. Recent studies have suggested that whole-body low-frequency vibration (WBLFV) may elicit an acute postactivation potentiation response, leading to acute improvements in power and force development. Potentially, the use of WBLFV between sets of resistance training rather than during training itself may lead to increased recruitment and synchronization of high-threshold motor units, minimize fatigue potential, and facilitate the chronic adaptation to resistance exercise. The purpose of this study was to determine the effects of applying TriPlaner, WBLFV, prior to and then intermittently between sets of Smith machine squats on short-term adaptations in explosive isometric force expression. Thirty recreationally resistance trained men aged 18-30 were randomly assigned to 1 of 3 groups: resistance training only (SQT, n = 11), resistance plus whole-body vibration (SQTV, n = 13), or active control (CON, n = 6). An isometric squat test was performed prior to and following a 6-week periodized Smith machine squat program. Whole-body low-frequency vibration was applied 180 seconds prior to the first work set (50 Hz, 2-4 mm, 30 seconds) and intermittently (50 Hz, 4-6 mm, 3 x 10 seconds, 60 seconds between exposures) within a 240-second interset rest period. Subjects were instructed to assume a quarter squat posture while positioning their feet directly under their center of mass, which was modified using a handheld goniometer to a knee angle of 135 +/- 5 degrees . Instructions were given to subjects to apply force as fast and as hard as possible for 3.5 seconds. Isometric force (N) and rates of force development (N.s(-1)) were recorded from the onset of contraction (F(0)) to time points corresponding to 30, 50, 80, 100, 150, and 250 milliseconds, as well as the peak isometric rate of force development (PISORFD), and rate of force development to

    The primary purpose of this study was to identify the relationship between muscle cross-sectional area (mCSA), echo intensity (EI), and body composition of Division I cross-country runners. The secondary purpose was to examine differences in these variables in athletes stratified based on stress-fracture (SFx) history. Thirty-six athletes were stratified based on sex and SFx history. A panoramic scan vastus lateralis was performed using a GE Logiq-e B-mode ultrasound. Echo intensity and mCSA were determined from the scan using a grayscale imaging software (ImageJ). Body composition measures were determined using dual-energy x-ray absorptiometry. For females, mCSA was significantly correlated with left leg lean mass (LM; R = 0.54) and EI (R = -0.57). Lean mass was significantly correlated with bone mineral density (BMD; R = 0.58) and bone mineral content (BMC; R = 0.56), whereas BMC was also correlated with leg LM (R = 0.72). For males, mCSA was significantly correlated with leg LM (R = 0.66), BMD (R = 0.50), and BMC (R = 0.54). Leg LM was significantly correlated with BMD (R = 0.53) and BMC (R = 0.77). Personal best times for males were significantly correlated with fat mass (R = 0.489) and %fat (R = 0.556) for the 10- and 5-km races, respectively. Female and male athletes with a history of SFx were not significantly different across any variables when compared with athletes with no history. These correlations suggest that more muscle mass may associate with higher BMD and BMC for stronger bone structure. Modifications in training strategies to include heavy resistance training and plyometrics may be advantageous for preventing risk factors associated with SFx reoccurrence.

    Emotional eating has been defined as eating in a response to negative emotions and it is associated with weight gain. The English version of Eating Appraisal Due to Emotions and Stress Questionnaire (EADES) was developed to assess how individuals use food in order to cope with stress and emotions. To analyze psychometric characteristics of Spanish version of EADES and to identify whether the constructs of EADES were associated with obesity in university students. The EADES (Spanish version) was administered to 232 Mexican university students from 18 to 29 years old. Body Mass Index (BMI) was calculated. A test-retest evaluation was conducted with 75 participants. Cronbach's alpha of EADES was 0.92; the interclass correlation coefficient was 0.88. Regarding BMI and EADES results, the subscale Emotion and Stress Related Eating was significantly associated with obesity (p = 0.026). Through factor analysis of the instrument, three factors were extracted and items that showed factor loading obesity and the 40-items version of the instrument, a statistically significance association was found for the total score (OR = 0.973, p = 0.020) and for the factor Self-confidence related to Emotional Eating component (OR = 0.940, p = 0.026). A good internal consistency and temporal stability of the Spanish version of the instrument were found; the 40-item EADES version was positively associated with obesity. This instrument could be useful in assessing emotional eating. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

    Eating disorders are rapidly increasing in young adults. But, a few studies have examined the risk of eating disorders and body image in university students of non-Western societies. The current study aimed to assess eating disorders risk in relation to body image and self-esteem among Iranian university students. The participants were 430 students from Tabriz, between April and May 2015. The 26-item Eating Attitude Test (EAT-26), Multidimensional Body-Self Relations Questionnaire (MBSRQ) and Rosenberg's Self-Esteem Questionnaires were used. EAT-26 score of 20 or more was considered as eating disorders risk cutoff. Majority of the students (68 %) were females. The overall eating disorders risk was 9.5 % (7.5 and 10.5 % in men and women, respectively). Further, the prevalence of poor body image and low self-esteem was 34.2 and 16 %, respectively. Neither of the gender differences was statistically significant (p > 0.05). In simple logistic regression, there were significant associations between self-esteem, body image, parental education and eating disorders risk (p self-esteem (OR = 0.37, 95 % = 0.16-0.87) and mother's education level (OR = 2.78, 95 % = 1.30-5.93) were predictors of eating disorders risk. The findings revealed that low self-esteem and mother's higher education may increase eating disorders risk and the predictive role of body image possibly is by other mediators such as self-esteem. This warrants awareness improvement and developing appropriate interventions targeting self-esteem and self-respect of students.

    There are many mechanisms in which stress can lead to weight gain thus high a BMI. The endocrine and inflammatory pathway can directly increase abdominal adiposity. Another way in which stress leads to weight gain is through changes in health behaviors. The study aimed to investigate the prevalence of musculoskeletal disorders (MSDs) among healthy students of Ahlia University, and to determine the relationship between the development of MSDs and academic stressors and body mass index. Self-administered questionnaires were distributed to 94 students aged 18-26 years who were enrolled at various Ahlia University colleges and met other inclusion criteria. The students responded to the standardized Nordic musculoskeletal questionnaire and the modified College Student Stress Inventory regarding musculoskeletal symptoms and academic stressors. Height and weight measurements were also obtained to determine body mass index. A total of 77.66% reported MSDs in one or more body part, with the prevalence being higher among women than among men. The 7-day prevalence of MSDs severe enough to interfere with activities of daily living was 60.64%, and 44.68% by female and male students, respectively. There was a significant relationship between academic stress and MSDs in the neck, shoulders, lower back, and hips, while the relationship between MSDs, and body mass index, academic stress, and grade point average was not significant. The prevalence of MSDs among Ahlia University students was found to be high. Apart from the positive correlation between academic stress and MSDs in certain body parts, other correlations were not significant.

    There has been an increase in ethno-cultural, linguistic, and socio-demographical diversity in students enrolling in undergraduate nursing programs. Diversity also involves other characteristics, but little is known about how diversity impacts on the clinical experiences of nursing students. The aim of this review is to identify studies which describe the clinical placement experiences of nursing students who have a broad range of diversity characteristics. Major databases were searched and original studies published from 2003 to 30 June 2013 were eligible for inclusion. An expanded definition of diversity was used to include characteristics such as ethnicity, language, age, religion, gender, socioeconomic status, carer responsibilities, sexual orientation and special needs/disability. Male gender and speaking English as a second language are diversity characteristics associated with a less positive clinical experience. These students are also more likely to leave their nursing program. Mature-aged students and those from ethnic minority groups were also noted to have a less positive clinical experience and in some cases, this also increased attrition. However, it was difficult to determine the impact of these characteristics alone as they appeared to be linked with other characteristics such as financial difficulties and carer responsibilities in the case of mature-aged students, and language and international student status in the case of ethnicity. Given the significant benefits associated with preparing a diverse nursing workforce, it is an imperative to better understand the impact of diversity on nursing students to ensure that every placement becomes a positive and valuable learning experience.

Answers to the matrix dealt with treatments including exploratory factor analyses, reserve of qualified items, and confirmatory factor analyses of latent structures. Results: Six latent factors, namely the Social Avoidance, Appearance Dissatisfaction, Preoccupation with Reassurance, Perceived Distress/Discrimination, Defect Hiding, and Embarrassment in Public, were identified. The factors and their respective items have composed a 24-item questionnaire named as the Body Image Concern Scale. Each factor earned a satisfactory internal reliability, and the intercorrelations between these factors were in a median level. Women scored significantly higher than men did on the Appearance Dissatisfaction, Preoccupation with Reassurance, and Defect Hiding. Conclusion: The Body Image Concern Scale has displayed its structure validation and gender preponderance in Chinese university students.

    impairment have stagnated compared with their peers in 8/1. Significant differences exist even within the group of deaf students in the three aspects of the study based on three dimensions of text, the terms of the speed of reading, significant differences exist also in the manifestation of errors and understanding of the text. Differences are also evident in terms of the degree of the hearing impairment, in terms of age and gender within the group of the deaf; this means that individual characteristics of students represent important facts.

    Modern team handball match-play imposes substantial physical and technical demands on elite players. However, only limited knowledge seems to exist about the specific working requirements in elite team handball. Thus, the purpose of this study was to examine the physical demands imposed on male elite team handball players in relation to playing position and body anthropometry. Based on continuous video recording of individual players during elite team handball match-play (62 tournament games, ∼4 players per game), computerized technical match analysis was performed in male elite team handball players along with anthropometric measurements over a 6 season time span. Technical match activities were distributed in 6 major types of playing actions (shots, breakthroughs, fast breaks, tackles, technical errors, and defense errors) and further divided into various subcategories (e.g., hard or light tackles, type of shot, claspings, screenings, and blockings). Players showed 36.9 ± 13.1 (group mean ± SD) high-intense technical playing actions per match with a mean total effective playing time of 53.85 ± 5.87 minutes. In offense, each player performed 6.0 ± 5.2 fast breaks, received 34.5 ± 21.3 tackles in total, and performed in defense 3.7 ± 3.5 blockings, 3.9 ± 3.0 claspings, and 5.8 ± 3.6 hard tackles. Wing players (84.5 ± 5.8 kg, 184.9 ± 5.7 cm) were less heavy and smaller (p handball match-play is characterized by a high number of short-term, high-intense intermittent technical playing actions. Indications of technical fatigue were observed. Physical demands differed between playing positions with wing players performing more fast breaks and less physical confrontations with opponent players than backcourt players and pivots. Body anthropometry seemed to have an important influence on playing performance because it is highly related to playing positions. The present observations suggest that male elite team handball players should implement more position

    Some phthalic acid esters (PAEs) and nonylphenol (NP) are endocrine-disrupting chemicals (EDCs) that are widely used in consumer products. Consequently, the general population is exposed simultaneously to both groups of chemicals. To investigate the single- and co-exposure effects of PAEs (DMP, DEP, DnBP, DiBP, BBzP, and DEHP) and NP on obesity and pubertal maturity to compare the body sizes of general adolescents with the complainants of the phthalate-tainted foods scandal that occurred in Taiwan. This study included 270 general adolescents aged 6.5-15.0 years and 38 complainants aged 6.5-8.5 years. Nine metabolites of the five PAEs and of NP were measured in urine. We used a questionnaire to evaluate pubertal maturity, measured anthropometric indices (APs) to assess body size, and collected urine samples to measure the two groups of chemicals. We found that urinary PAE metabolite concentrations (specifically, metabolites of DEP, DnBP, DiBP, and DEHP) were positively associated with the APs for abdominal obesity (including skinfold thickness, waist circumference, waist-to-height ratio, and waist-to-hip) and indicated a dose-response relationship. Mono-methyl phthalate (MMP) exposure was inversely associated with pubarche among boys. The daily intake of DEHP in general adolescents exceeded the reference doses (RfD-20 μg/kgbw/day) and tolerable daily intake (TDI-50 μg/kgbw/day) by 3.4% and 0.4%, respectively. No associations were observed between NP exposure or co-exposure and the APs or pubertal maturity. No significant differences were observed between general adolescents and the complainants with regard to weight, height, or BMI. The study suggests that PAE (specifically, DEP, DnBP, DiBP, and DEHP) exposure is associated with abdominal obesity in adolescents and that the APs for abdominal obesity are more sensitive than BMI for measuring obesity among adolescents. We suggest that the RfD and TDI for PAEs should be revised to provide sufficient protection

    In Japan, the maldistribution of physicians between urban and rural areas is increasing. It is important to know the practice location expectations of future physicians. The study was designed as a cross-sectional survey. In 2009-2013, students at a medical school in Japan completed a questionnaire containing 50 items with four-point Likert scales. The students rated the importance of specified individual and occupational aspects. Furthermore, students were asked to state their intention to practice in a rural area. The study sample consisted of 368 students (88.2% response rate). Significant variables that were associated with a positively motivated intent for rural practice were 'presence of a role model' (odds ratio (OR), 5.42; 95% confidence interval (CI), 1.58-18.5), 'admission by school recommendation' (OR, 7.68; 95%CI, 2.14-27.6), 'growing up in a rural area' (OR, 6.16; 95%CI, 1.01-37.6), 'general medicine/family medicine as the first career choice' (OR, 5.88; 95%CI, 2.43-14.2), 'interest in the targeted population' (OR, 16.7; 95%CI, 3.97-69.9), 'memorable experience at a class or clinical rotation' (OR, 3.94; 95%CI, 3.73-416), and 'location of their medical school' (OR, 11.4; 95%CI, 2.79-46.2). The present study suggests that medical schools might recruit students with characteristics associated with intention for rural practice.

    Full Text Available This cross-sectional study aimed to explore the socio-demographic and career choice characteristics of dental students in two publicly funded universities in Chile. A total of 601 dental students participated in the study with a 53% response rate.The written survey covered age, gender, type of school attended, place of residence, parental occupation, level of education, tuition fees payment methods, along with motivations and preferences towards dentistry as a career. The respondents had an average age of 22 years old. Sixty one percent of respondents were female, and the majority had completed secondary education in private and subsidized schools with only 21.5% having finished in public schools. Most of the students covered their tuition fees with parental money (37.1%, followed by any type of loan (27.9%. The majority of students (63.8% had placed dentistry as their first career choice with self-motivation being the most important reason for their decision. This study provides a description of the socio-demographic and economic profile of Chilean dental students and provides insights about career decision issues. It also purposes areas for further research and management by academics for future program development.

    Full Text Available This research makes use of hierarchical linear modelling to investigate which teacher characteristics are significantly associated with student performance. Using data from the SACMEQ III study of 2007, an interesting and potentially important finding is that younger teachers are better able to improve the mean mathematics performance of their students. Furthermore, younger teachers themselves perform better on subject tests than do their older counterparts. Identical models are run for Sub Saharan countries bordering on South Africa, as well for Kenya and the strong relationship between teacher age and student performance is not observed. Similarly, the model is run for South Africa using data from SACMEQ II (conducted in 2002 and the relationship between teacher age and student performance is also not observed. It must be noted that South African teachers were not tested in SACMEQ II so it was not possible to observe differences in subject knowledge amongst teachers in different cohorts and it was not possible to control for teachers’ level of subject knowledge when observing the relationship between teacher age and student performance. Changes in teacher education in the late 1990s and early 2000s may explain the differences in the performance of younger teachers relative to their older counterparts observed in the later dataset.

    Short sleep has been linked to obesity. However, sleep is a multidimensional behavior that cannot be characterized solely by sleep duration. There is limited study that comprehensively examined different sleep characteristics in relation to obesity. We examined various aspects of sleep in relation to adiposity in 2005-2006 NHANES participants who were 18 or older and free of cardiovascular disease, cancer, emphysema, chronic bronchitis and depression ( N  = 3995). Sleep characteristics were self-reported, and included duration, overall quality, onset latency, fragmentation, daytime sleepiness, snoring, and sleep disorders. Body measurements included weight, height, waist circumference, and dual-energy X-ray absorptiometry measured fat mass. Snoring was associated with higher BMI (adjusted difference in kg/m 2 comparing snoring for 5+ nights/week with no snoring (95 % confidence interval), 1.85 (0.88, 2.83)), larger waist circumference (cm, 4.52 (2.29, 6.75)), higher percentage of body fat (%, 1.61 (0.84, 2.38)), and higher android/gynoid ratio (0.03 (0.01, 0.06)). The associations were independent of sleep duration and sleep quality, and cannot be explained by the existence of sleep disorders such as sleep apnea. Poor sleep quality (two or more problematic sleep conditions) and short sleep duration (body size and fat composition, although the effects were attenuated after snoring was adjusted. In a nationally representative sample of healthy US adults, snoring, short sleep, and poor sleep quality were associated with higher adiposity.

    Spondyloarthritides are a group of inflammatory rheumatological diseases that cause arthritis with a predilection for spinal or sacroiliac involvement in addition to a high association with HLA-B27. Juvenile spondyloarthritis is distinct from adult spondyloarthritis and manifests more frequently as peripheral arthritis and enthesitis. Consequently juvenile spondyloarthritis is often referred to as enthesitis-related arthritis (ERA) subtype under the juvenile idiopathic arthritis (JIA) classification criteria. The American College of Rheumatology Treatment Recommendations for JIA, including ERA, are based on the following clinical parameters: current treatment, disease activity and the presence of poor prognostic features. The MRI features of juvenile spondyloarthritis include marrow edema, peri-enthesal soft-tissue swelling and edema, synovitis and joint or bursal fluid. Marrow edema is nonspecific and can be seen with other pathologies as well as in healthy subjects, and this is an important pitfall to consider. With further longitudinal study and validation, however, whole-body MRI with dedicated images of the more commonly affected areas such as the spine, sacroiliac joints, hips, knees, ankles and feet can serve as a more objective tool compared to clinical exam for early detection and monitoring of disease activity and ultimately direct therapeutic management.

    Free-to-roll wind tunnel tests were conducted and a computer simulation exercise was performed in an effort to investigate in detail the mechanism of wing rock on a configuration that consisted of a highly-slender forebody and a 78 deg swept delta wing. In the wind tunnel test, the roll angle and wing surface pressures were measured during the wing rock motion. A limit cycle oscillation was observed for angles of attack between 22 deg and 30 deg. In general, the wind tunnel test confirmed that the main flow phenomena responsible for the wing-body-tail wing rock are the interactions between the forebody and the wing vortices. The variation of roll acceleration (determined from the second derivative of the roll angle time history) with roll angle clearly showed the energy balance necessary to sustain the limit cycle oscillation. Pressure measurements on the wing revealed the hysteresis of the wing rock process. First, second and nth order models for the aerodynamic damping were developed and examined with a one degree of freedom computer simulation. Very good agreement with the observed behavior from the wind tunnel was obtained.

    Ovulatory dysfunction is a group of disorders with variable clinical presentations occasionally having serious long-term adverse effects. It accounts for 30% of female fertility problems. Evidence suggests an association between an individual's weight and disorders of ovulation. The objective of our study was to describe the clinical and hormonal profile of subfertile women with ovulatory dysfunction in relation to their body mass index (BMI). Methods: This prospective, descriptive study was carried out in Mother and Child Health Centre, PIMS, Islamabad and Railway hospital, Rawalpindi from April 2001 to March 2007. One hundred and thirty eight infertile patients with ovulatory dysfunction were included. The clinical data including BMI of each patient was recorded in addition to reports of investigations comprised of cervical smear, pelvic ultrasound and hormonal profile. Results: Primary infertility was found in 61% while secondary in 39% of the patients. The mean age was 29 years and mean duration of infertility was 6 years. Menstrual pattern was normal in 56.5%. BMI was normal in 30.4% while most patients were overweight and obese. Prolonged cycles, history of systemic endocrine disorders, abnormal vaginal discharge, hirsutism, polycystic ovarian morphology and hormonal abnormalities were more frequent in patients with increased BMI. During the study period, 21.7% of the women conceived. Conclusion: Infertile patients with ovulatory dysfunction present more frequently with primary infertility. They usually have higher than required BMI. Oligomenorrhoea amenorrhoea, hirsutism and hormonal abnormalities are more frequent in overweight than infertile patients with ovulatory dysfunction having a normal BMI. (author)

  3. Whole-body imaging of whole-organ, subresolution, basic functional unit (BFU) perfusion characteristics

    A BFU is an organ's smallest assembly of diverse cells that functions like the organ, such as the liver's hepatic lobules. There are approximately 107 BFUs in a human organ. These 100-200 μm structures are perfused by capillaries fed by a terminal arteriole (15μm diameter). BFU sizes, function and number per organ vary with disease, either by loss of BFUs and/or their decrease in function. The BFU is the upper limit of a spherical assembly of cells, immersed in a suitably nutrient medium, which can survive without its own blood supply. However, each BFU has its own blood supply to support the extra energy and/or solutes needed for providing its physiological function (e.g., contraction or secretion). A BFU function is best evaluated by its micro-perfusion, which can be readily evaluated with whole-body CT. Resolution of individual BFUs within in-situ organs, using clinical imaging devices, would require high radiation doses and/or the intolerably long scan-durations needed for suitable signal-to-noise image-data. However, it is possible to obtain a statistical description of the BFU number, size and function from wholebody CT by way of a model. In this study we demonstrate this capability by using the distribution of myocardial terminal arteriolar perfusion territories by way of a nested, multiple, regions-of-interest analysis of the heart wall imaged during transient opacification of its blood supply.

    College students are in transition from adolescence to adulthood, and it has been reported that they show poor dietary habits. This study was conducted to compare body image perception, nutrition knowledge, dietary attitudes, dietary habits, and health-related lifestyles between Korean college students (KCS) and Mongolian college students (MCS). Subjects were 314 KCS and 280 MCS. The data includes results of self-administered questionnaires; statistical analysis was performed using the SPSS 23.0 program. With regards to body image perception, KCS perceived themselves to be fatter on current body image than ideal body image compared to MCS; 64.0% of KCS and 34.6% of MCS desired to be thinner. Total score of nutrition knowledge in KCS (17.0) was significantly higher compared to MCS (8.4) ( P correlation with dietary attitudes in MCS ( P mobile phone usage ( P < 0.001), compared to MCS. This study suggests that development of nutrition education program which is effective and proper is required to improve healthy dietary habits among college students of both countries. Essential contents should include acquirement of nutrition knowledge and a motivation for its application to actual life for KCS, and improvement of healthy dietary habits for MCS.

    Full Text Available Background and aims   Educating of students that have the ability to solve society problems, is considered as the most important task of universities. This important issue is achieved through effective education in a safe and stress free environment. Proper design of classroom seats proportional to anthropometric characteristics of students not only can improve academic quality but also prevent musculoskeletal disorders. In addition it may encourage students to practice correct sitting habits. This study was conducted to check the correlation of physical dimensions of students and prevalence of musculoskeletal disorder with educational chair dimensions that provided by companies.   Methods   This descriptive - analytical study was performed on 115 students of 18 to 27 years. 15 anthropometric parameters correlated with sitting on the chair were measured by anthropometry page and anthropometric caliper gauge. Dimensions of two Types of seats provided in the classrooms were compared with the standard seat dimensions.   Results   comparison of dimensions confirmed that seat dimension and students dimensions correspond with one another only in elbow length parameter and other parameters were not correspondent with each other. T-Test showed that there are significant  differences between girl and boy parameters.  conclusion   Comparison of the results of measurement of  physical dimensions and chair dimensions with results of emotional dissatisfaction questionnaire and body map chart showed that plastic chair is better than wooden type in term of comfort, chair kind and slope of back rest, and in using plastic chairs students do not have to change their sitting postures; however,  due to incorrect design of foot rest and high effective depth of sea,،  discomfort and pain in lower limbs is higher in plastic chairs when compared with wooden chairs.

    To develop and crossvalidate new equations for predicting basal metabolic rate (BMR) in obese children and adolescents in relation to pubertal stages, anthropometric characteristics or body composition. A total of 1696 obese Caucasian children and adolescents (mean body mass index z-score: 3.5±0.8) participated in this study. BMR was determined by indirect calorimetry and fat-free mass (FFM) and fat mass (FM) by bioelectrical impedance analysis. Equations were derived by stepwise multiple regression analysis using a calibration cohort of 848 subjects, and the equations were crossvalidated with a Bland and Altman method in the remaining 848 subjects. Two new specific equations based on gender (1: males; 0: females), pubertal stages (from 1 to 5, assessed according Marshall & Tanner methods) and body weight (BW, kg), stature (m) or body composition (kg) were generated as follows: (1) BMR=(BW × 0.044)+(stature × 2.836)-(pubertal stage × 0.148)+(gender × 0.781)-0.551 (adjusted coefficient of determination (R(2)adj)= 0.69 and root mean squared error (RMSE)=0.954 MJ); (2) BMR=(FFM × 0.082)+(FM × 0.037)-(pubertal stage × 0.125)+(gender × 0.706)+2.528 (R(2)adj= 0.70 and RMSE=0.943 MJ). In the crossvalidation group, mean-predicted BMR was not significantly different from the mean-measured BMR (MBMR) for all children and adolescents, as well as for boys and girls (differenceBMR was predicted accurately (90-110% of MBMR) in 67% of subjects. The new prediction equations considering the pubertal stages allow an accurate and more appropriate (vs equations using chronological age) estimation of BMR in obese children and adolescents.

    Anthropometric reference data for older adults, particularly for the oldest old, are still limited, especially in developing countries. The aim of the present study was to describe sex- and age-specific distributions of anthropometric measurements and body composition in Mexican older adults. The methods included in the present study were assessment of height, weight, BMI, calf circumference (CC), waist circumference (WC) and hip circumference (HC) as well as knee height in a sample of 8883 Mexican adults aged 60 years and above and the estimation of sex- and age-specific differences in these measures. Results of the study (n 7865, 54% women) showed that men are taller, have higher BMI, and larger WC than women, whereas women presented higher prevalence of obesity and adiposity. Overall prevalence of underweight was 2·3% in men and 4·0% in women, with increasing prevalence with advancing age. Significant differences were found by age group for weight, height, WC, HC, CC, BMI and knee height (P<0·001), but no significant differences in waist-hip circumference were observed. Significant differences between men and women were found in height, weight, circumferences, BMI and knee height (P<0·001). These results, which are consistent with studies of older adults in other countries, can be used for comparison with other Mexican samples including populations living in the USA and other countries with similar developmental and socio-economic conditions. This information can also be used as reference in clinical settings as a tool for detection of individuals at risk of either underweight or overweight and obesity.

    Full Text Available The Body Appreciation Scale (BAS was developed by Avalos, Tylka & Wood-Barcalow (2005 to determine body appreciation. The present study examined the factor structure of the BAS among Turkish women and men university students. For this purpose, confirmatory factor analysis (competing model analysis was conducted to evaluate the factor structure the BAS. Results from the confirmatory factor analysis on 741 university student (431 women; 310 men suggested that a two-factor model with four items deleted represents an adequate description of the data, and best of the factor model proposed. In terms of convergent validity of the scale a negative and significant correlation was found between body appreciation and social appearance anxiety for women and men samples. The Turkish version of the BAS demonstrated adequate internal consistency and composite reliability. Finally, findings from t-test analysis showed that the BAS scores did not differ according to gender.

    Approximately 25% of US 2-to-5-year olds are overweight and ethnic minority groups are disproportionately affected. We explored the relationship between parent demographic characteristics, various perinatal/early childhood (EC) factors, and child body mass index (BMI) to determine possible contributors to these disparities. A preschool-based randomized controlled (N = 28 centers) obesity prevention intervention was conducted among multiethnic 2-to-5 year olds. Baseline assessment of demographic characteristics, various perinatal/EC factors, and child BMI were analyzed via generalized linear mixed models and logistic regression analysis. Foreign-born parents were almost 2.5 times as likely to have an obese child versus children of US-born parents (OR 2.43, 95% CI 1.53-3.87). Families who spoke Spanish only or a combination of Creole/English at home were over twice as likely to have an obese preschool child versus families who spoke English only at home. Parent place of birth and language spoken at home plays a significant role in early childhood obesity. Future early childhood healthy weight initiatives should incorporate strategies that take into account these particular parent characteristics.

    Full Text Available The aim of the present study was twofold. The first aim was to examine the influence of absolute and relative lower body muscle force on kinematic component which determine the start performance. The second aim was to create multiregressional model which could use as a tool for swimming coaches with the purpose to start performance control and improvement. Twenty seven high-level trained male competitive swimmers all members of the Serbian National Youth and Senior Swimming Team (Age = 21.1 ± 4.3 yrs., Height = 1. 89 ± 0.10 m, Weight = 81.6 ± 8.4 kg, 50m freestyle - long course = 24.36 ± 0.86 s performed two trials of standing leg extensors isometric muscle force testing and three swimming start trials corresponding to 10m distance. The average start time significantly correlated with variables of leg extensors maximum voluntary force (Fmax, r = -0.559, p = 0.002, leg extensors relative muscle voluntary force (Frel, r = -0.727, p < 0.001, leg extensors specific rate of force development (RFD50%, r = -0.338, p = 0.047 and leg extensors relative value of specific rate of force development (RFD50%rel, r = -0.402, p = 0.040. Regression equation for t10m prediction was defined by following variables: maximum voluntary isometric force of leg extensors muscles at absolute and relative level (Fmax and Frel, as well as a specific rate of force development of the same muscle groups (RFD50% and RFD50%rel at absolute and relative level too with 74.4% of explained variance. Contractile abilities indicators of the leg extensors muscles included consideration: Fmax, RFD50%, Frel and RFD50%rel showed significant correlation with swimming start times on 10m. Additionally, the results suggest that swimmers, who possess greater isometric maximum force and specific rate of force development at absolute and relative levels, tend to be able to swim faster on initial 10m swim start perforamnce.

    With the increase of railway wagon axle load and the growth of marshalling quantity, the problem caused by impact and vibration of vehicles is increasingly serious, which leads to the damage of vehicle structures and the components. In order to improve the reliability of longitudinal connection model for vehicle impact tests, a new railway wagon longitudinal connection model was developed to simulate and analyse vehicle impact tests. The new model is based on characteristics of longitudinal force transmission for vehicles and parts. In this model, carbodies and bogies were simplified to a particle system that can vibrate in the longitudinal direction, which corresponded to a stiffness-damping vibration system. The model consists of three sub-models, that is, coupler and draft gear sub-model, centre plate sub-model and carbody structure sub-model. Compared with conventional draft gear models, the new model was proposed with geometrical and mechanical relations of friction draft gears considered and with behaviours of sticking, sliding and impact between centre plate and centre bowl added. Besides, virtual springs between discrete carbodies were built to describe the structural deformation of carbody. A computation program for longitudinal dynamics based on vehicle impact tests was accomplished to simulate. Comparisons and analyses regarding the train dynamics outputs and vehicle impact tests were conducted. Simulation results indicate that the new wagon longitudinal connection model can provide a practical application environment for wagons, and the outputs of vehicle impact tests agree with those of field tests. The new model can also be used to study on longitudinal vibrations of different vehicles, of carbody and bogie, and of carbody itself.

    Understanding the modifiable factors that improve and maximize peak bone mass at an early age is necessary to design more effective intervention programs to prevent osteoporosis. To identify these modifiable factors, we analyzed the relationship of physical activity (PA), physical fitness, body composition, and dietary intake with bone stiffness index (SI), measured by quantitative ultrasonometry in young university students (18-21 years). Moderate-to-vigorous PA (MVPA) was the strongest predictor of SI (β = 0.184; p = 0.035). SI was most closely related with very vigorous PA in males (β = 0.288; p = 0.040) and with the number of steps/day in females (β = 0.319; p = 0.002). An association between thigh muscle and SI was consistent in both sexes (β = 0.328; p < 0.001). Additionally, extension maximal force was a bone SI predictor factor in females (β = 0.263; p = 0.016) independent of thigh muscle perimeter. Calcium intake was the only nutrition parameter that had a positive relationship with SI ( R = 0.217; p = 0.022). However, it was not included as a predictor for SI in our regression models. This study identifies predictors of bone status in each sex and indicates that muscle and bone interrelate with PA and fitness in young adults.

    The primary purpose of this study was to describe dietary intakes among Canadian undergraduate students enrolled in an Introductory Nutrition course. A secondary objective was to determine food group servings associated with meeting more Dietary Reference Intakes (DRIs) of select nutrients and with a lower body mass index (BMI). Participants (n = 124, 20.7±3.2yrs) provided output from a 3-day dietary record and completed a physical activity/demographics questionnaire. Linear regression showed that the dietary intake associated with meeting the most DRIs included vegetables, fruits, protein foods, and dairy (p = 0.001). Protein foods were a positive predictor and fruit a negative predictor of BMI (p = 0.001 and p = 0.023 respectively). Males consumed more grains (p = 0.001), dairy (p = 0.04), protein foods (p empty calories (p = 0.007) and total calories than females (p < 0.001). A diet characterized by greater intake of vegetables, fruits, protein foods, and dairy was associated with a Canadian undergraduate population meeting the greatest number of nutrient requirements.

    Although self-compassion is associated with healthier body image and eating behavior, these findings have generally emerged at the between-persons level only. The present study investigated the unique contributions of within-person variability in self-compassion, and between-persons differences in self-compassion, to body image and eating behavior. Over seven days, 92 female college students completed nightly measures of self-compassion, self-esteem, dietary restraint, intuitive eating, body appreciation, body satisfaction, and state body image. Multilevel modeling revealed that within-persons, day-to-day fluctuations in self-compassion contributed to day-to-day fluctuations in body image and eating. Between-persons, participants' average levels of self-compassion across days contributed to their average levels of body image and eating over the week. Results generally held when controlling for within- and between-persons self-esteem. Evidently, the eating and body image benefits of self-compassion may come not only from being a generally self-compassionate person, but also from treating oneself more self-compassionately than usual on a given day.

    The aim of this study was to examine the relationships between gender and the educational grade on the one hand, and physical activity levels, motivation, self-identity, body dissatisfaction, the intention to be physically active and daily sitting time on the other, in a sample of Spanish high school adolescents. The sample consisted of 2087 Spanish students from the 3rd (n = 1141) and 4th grade (n = 946), both male (n = 1046) and female (n = 1041), ranging in age from 15 to 17 years old (M = 15.42; SD = .86). Students completed questionnaires to assess their levels of physical activity, self-identity, motivation, intention to be physically active and daily sitting time. The students' perceptions of their body height and mass were also tested. With the exception of walking MET values, the results showed gender differences in the variables tested. Male participants showed higher intrinsic motivation and lower amotivation than female participants. Furthermore, male students revealed higher levels of physical activity than female students. Finally, the research concluded with the importance of promoting intrinsic reasons for physical activity in order to encourage positive consequences in high school students.

    A national randomly selected survey of a sample of deaf and hard-of-hearing students included in regular classes from kindergarten to high school in Australian preschools and schools was conducted via a questionnaire to itinerant teachers working with such students. This article reports the analysis of a questionnaire that surveyed the demographic characteristics of such students and a set of characteristics of their behavior in their placement in terms of "participation" in aspects of regular class activities. These aspects were level of integration, academic participation, level of independence, and social participation. Data are reported and analyzed in terms of the above demographic and participatory characteristics of the students. We consider comparisons with comparable reports from the United States and Great Britain and discuss implications for deaf and hard-of-hearing students included in regular classes.

    In the past six decades, the Kuwaiti population has been exposed to rapid transformation in the quality of diet intake, daily activities, and career types. This major socioeconomic shift was accompanied by the introduction of both communicable and noncommunicable chronic diseases afflicting people of all ages. This article aims to detect a relationship between sociocultural characteristics-such as physical activity, dietary habits, and smoking-and the prevalence of metabolic syndrome (MetS). A descriptive, cross-sectional survey was conducted among 262 male university students in Kuwait; participants were selected by using a convenient nonrandom opportunistic sample. Associated social and health factors were obtained using a closed-ended questionnaire. BMI and blood tests that include clusters of MetS risk components were drawn from participants in primary health care clinics. More than half of the participants were overweight and obese; 74.4% of the participants reported they did not visit a nutritionist; 69.8% said that they are currently not on a diet; 53.4% of the students were nonsmokers; 42.7% reported moderate to very low daily physical activity. The prevalence of MetS components increased among students with older age, employed, and married ( p students needs to be considered by Kuwaiti community members and the government to highlight the risk factors of MetS on individuals' well-being, quality of life, and life expectation.

    Full Text Available The Arabic scale for teachers' ratings of basic education gifted students' characteristics is one of the most common Arabic measures used for initial identification of gifted students in some Arabic countries. One of the shortcomings of this scale is that it is based on the classical the-ory of measurement. This study sought to reval-idate the scale in the light of Rasch modeling which rests upon the modern theory of meas-urement and to develop different criteria for in-terpreting the levels of individuals' traits. The scale was administered to 830 of Basic Educa-tion students in Khartoum (ages ranged from 7 to 12 years. Two groups of students partici-pated in the study: a calibration sample (N = 250 and a standardization sample (N = 580. The statistical treatments were performed using the PSAW 18 and RUMM 2020 programs ac-cording to Rasch's unidimentional model. Six of the scale's items were deleted for not conform-ing to Rasch Modeling. This left the scale with 31 items. Besides, new criteria for the scale were developed by obtaining the t-scores and special education scores that match the various ratings of the individuals' ability.

  8. The Characteristics and Experiences of Successful Undergraduate Latina Students Who Persist in Engineering

    Robinson, Carrie

    Females and underrepresented ethnic minorities earn a small percentage of engineering and computer science bachelor's degrees awarded in the United States, earn an even smaller proportion of master's and doctoral degrees, and are underrepresented in the engineering workforce (Engineering Workforce Commission, [2006], as cited in National Science Foundation, 2012; United States Department of Education, [2006], as cited in National Science Foundation, 2009a; United States Department of Education, [2006], as cited in National Science Foundation, 2009b). Considerable research has examined the perceptions, culture, curriculum, and pedagogy in engineering that inhibits the achievement of women and underrepresented ethnic minorities. This action research study used a qualitative approach to examine the characteristics and experiences of Latina students who pursued a bachelor's degree in the Ira A. Fulton Schools of Engineering at Arizona State University (ASU) as part of the 2008 first-time full-time freshman cohort. The researcher conducted two semi-structured individual interviews with seven undergraduate Latina students who successfully persisted to their fourth (senior) year in engineering. The researcher aimed to understand what characteristics made these students successful and how their experiences affected their persistence in an engineering major. The data collected showed that the Latina participants were motivated to persist in their engineering degree program due to their parents' expectations for success and high academic achievement; their desire to overcome the discrimination, stereotyping, and naysayers that they encountered; and their aspiration to become a role model for their family and other students interested in pursuing engineering. From the data collected, the researcher provided suggestions to implement and adapt educational activities and support systems within the Ira A. Fulton Schools of Engineering to improve the retention and graduation rates

    The present study aimed to investigate the relationship between ORTO-15 score and obsessive-compulsive symptoms, disordered eating patterns and body uneasiness among female and male university students and to examine the predictive model of ORTO-15 in both groups. One hundred and twenty students participated in the present study (mean age 22.74 years, SD 7.31). The ORTO-15 test, the Maudsley Obsessive-Compulsive Questionnaire, the Eating Attitudes Test-26 and the Body Uneasiness Test were used for the present study. Our results revealed no gender differences in ORTO-15 score. Our results show, rather unexpectedly, that in female students lower scores, corresponding to greater severity, were related to less pathological body image discomfort and obsessive-compulsive signs, while in male students, lower ORTO-15 scores were related to less pathological eating patterns, as behaviors and symptoms. Further studies regarding the relationship between ON and anorexia nervosa, as well as obsessive-compulsive symptoms, are needed to better understand the causality.

    School-based body mass index (BMI) screening and parent notification programs have been recommended as a childhood overweight prevention strategy. However, there are little empirical data available to guide decision making about the acceptability and safety of programs. A pilot study was conducted using a quasiexperimental research design. In fall 2004, children in 4 suburban elementary schools (kindergarten to sixth grade) in the St Paul/Minneapolis, MN, metropolitan area completed height/weight screening. The following spring, parents in 2 schools received letters containing height/weight and BMI results. A self-administered post-only survey examined parents' opinions and beliefs regarding school-based BMI screening and parent notification programs (response rate: 790/1133 = 70%). The chi2 test of significance was used to examine differences in program support by treatment condition, child's weight status, and sociodemographic characteristics. Among all parents, 78% believed it was important for schools to assess student's height/weight annually and wanted to receive height, weight, and BMI information yearly. Among parents receiving the letter, 95% read most/all of the letter. Most parents (80%) and children (83%) reported comfort with the information in the letter. Parents of overweight children were more likely to report parental discomfort as well as child discomfort with letter content. There was considerable parental support for school-based BMI screening and parent notification programs. Programs may be a useful overweight prevention tool for children. However, continued attention to how best to support parents and children affected by overweight is required.

    Full Text Available Objective: The aim of this study was to examine the association between individual and school context characteristics with the body mass index of Portuguese children. Methods: The sample comprised 1641 children (847 boys aged 6–10 years from the North and Central regions of Portugal. Regarding the individual characteristics, age, gender, city of residence, levels of physical activity, and physical fitness were assessed. Concerning the school context characteristics, the surrounding environment, school size, presence of recreational characteristics and space, and presence of a sports court and of physical education classes were considered. Children's body mass index was the dependent variable. The multilevel analysis was carried out in HLM 7.0 software. Results: The predictors of the child and the school context explained, respectively, 97.3% and 2.7% of the total body mass index variance. Regarding the individual characteristics, older children, boys, and those who had lower performance at the 1‐mile run/walk, curl‐up, push‐up, and higher performance in trunk lift tests showed higher BMI. Further, urban schools with higher recreational spaces were positively associated with children's body mass index. Conclusion: School context variables have a reduced effect on body mass index variation compared to the children's biological and behavioral characteristics. The authors therefore encourage strategies that aim to increasing children's physical fitness levels to help prevent excess weight.

Less is known about how such factors may differ for various students. In addition, not much is known about differences in the process of how factors influence students' learning and what creates differences in procrastination behavior between students with different levels of academic procrastination. In this study learning characteristics and the self-regulation behavior of three groups of students with different levels of academic procrastination were compared. The rationale behind this was that certain learning characteristics and self-regulation behaviors may play out differently in students with different levels of academic procrastination. Participants were first-year students ( N = 22) with different levels of academic procrastination enrolled in an elementary teacher education program. The selection of the participants into three groups of students (low procrastination, n = 8; average procrastination, n = 8; high procrastination, n = 6) was based on their scores on a questionnaire measuring the students' levels of academic procrastination. From semi-structured interviews, six themes emerged that describe how students in the three groups deal with factors that influence the students' learning: degree program choice, getting started with study activities, engagement in study activities, ways of reacting to failure, view of oneself, and study results. This study shows the importance of looking at differences in how students deal with certain factors possibly negatively influencing their learning. Within the group of students with average and high levels of academic procrastination, factors influencing their learning are regularly present. These factors lead to procrastination behavior among students with high levels of academic procrastination, but this seems not the case among students with an average level of academic

    Full Text Available In order to foster leaders and supporters of fixed-point observation for sustainable forest management, it is considered effective to focus on students who have demonstrated potential for fixed-point observations of forests in the universal education stage. This study aims to identify the characteristics of students who frequently conduct plant observations, which is the basis for the fixed-point observation of forests, including methods involving photography. We conducted a questionnaire survey, which consisted of 19 questions that provided insight into junior high school students’ experiences, opportunities, and interests related to plant observation. We compared students who have conducted plant observations with those who have not, using Fisher’s exact test and multiple comparisons using the Benjamini and Hochberg method. The ratio of students who frequently conducted plant observations was significantly higher among female students than male students, and their characteristics differed by gender. The significant characteristics of male students included farm work experience and niche hobbies such as camping and lighting a bonfire, as well as using digital single-lens reflex cameras for photography; female students had relatively niche hobbies such as enjoying science. Students who increased the frequency of plant observations after the lecture about fixed-point observations of forests had an inclination toward social studies and tended not to use a smartphone for photography.
