    In Jengum (Federal Republic of Germany) EWE Gasspeicher GmbH (Oldenburg, Federal Republic of Germany) and astora GmbH and Co. KG (Kassel, Federal Republic of Germany) constructed commonly the second largest natural gas storage facility in Germany. With a planned storage capacity of 2.2 billion cubic meters of natural gas, this natural gas storage facility project provides a significant contribution to the energy supply in Germany. Technical measures such as cathodic corrosion protection play an important part in the construction of the natural gas storage facilities: All underground components of this storage facility have to be protected effectively against corrosion from security aspects and value-preserving aspects. For this, challenges such as topography, geology and structural features have to be considered. Furthermore, different operational requirements of each installation (sol technology and gas operation) are to be considered previously. This was achieved by means of a consistent implementation of the system-specific LKS protection plan and by means of a continuous supervision.

  14. Experimentally induced, synergistic late effects of a single dose of radiation and aging: significance in LKS fraction as compared with mature blood cells.

    The number of murine mature blood cells recovered within 6 weeks after 2-Gy whole-body irradiation at 6 weeks of age, whereas in the case of the undifferentiated hematopoietic stem/progenitor cell (HSC/HPC) compartment [cells in the lineage-negative, c-kit-positive and stem-cell-antigen-1-positive (LKS) fraction], the numerical differences between mice with and without irradiation remained more than a year, but conclusively the cells showed numerical recovery. When mice were exposed to radiation at 6 months of age, acute damages of mature blood cells were rather milder probably because of their maturation with age; but again, cells in the LKS fraction were specifically damaged, and their numerical recovery was significantly delayed probably as a result of LKS-specific cellular damages. Interestingly, in contrast to the recovery of the number of cells in the LKS fraction, their quality was not recovered, which was quantitatively assessed on the basis of oxidative-stress-related fluorescence intensity. To investigate why the recovery in the number of cells in the LKS fraction was delayed, expression levels of genes related to cellular proliferation and apoptosis of cells in the bone marrow and LKS fraction were analyzed by real-time polymerase chain reaction (RT-PCR). In the case of 21-month-old mice after radiation exposure, Ccnd1, PiK3r1 and Fyn were overexpressed solely in cells in the LKS fraction. Because Ccnd1and PiK3r1 upregulated by aging were further upregulated by radiation, single-dose radiation seemed to induce the acceleration of aging, which is related to the essential biological responses during aging based on a lifetime-dependent relationship between a living creature and xenobiotic materials.

    The Lysholm Knee Score (LKS) is widely used and is one of the most effective questionnaires employed to assess knee injuries. Although LKS has been translated into multiple languages, there is no Chinese version even though China has the largest population of patients with knee-joint injuries. The objective of our study was to develop the Chinese version of LKS (C-LKS) and assess its reliability, validity and responsiveness in Chinese patients with anterior cruciate ligament (ACL) injuries. Study participants were mainly recruited among patients with ACL injuries scheduled for arthroscopic ACL reconstruction at our hospital. First, we developed the C-LKS in a five-step translation and cross-cultural adaptation procedure. Next, we calculated the Cronbach's alpha, intraclass correlation coefficient (ICC), Pearson's correlation coefficient (r), effect size (ES), and standardized response mean (SRM) to evaluate the reliability, validity, and responsiveness of C-LKS respectively. Overall, 126 patients with ACL injuries successfully completed the questionnaires. Acceptable internal consistency (Cronbach's alpha = 0.726) as well as excellent test-retest reliability (ICC = 0.935) was found for C-LKS. Good or moderate correlation (r = 0.514-0.837) was determined among C-LKS and International Knee Documentation Committee Subjective Knee Form (IKDC), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), physical subscales of SF-36; C-LKS also had fair or moderate correlation (r = 0.207-0.462) with the other subscales of SF-36, which adequately illustrated that good validity was included in C-LKS. In addition, good responsiveness was also observed in C-LKS (ES = 1.36,SRM = 1.26). We have shown that our developed C-LKS questionnaire is reliable, valid and responsible for the evaluation of Chinese-speaking patients with ACL injuries and it would be an effective instrument.

    2014-01-01

    Full Text Available Landau-Kleffner syndrome (LKS is a rare childhood disorder characterized by acquired aphasia and epilepsy. 99mTc-ECD SPECT imaging was performed in two right-handed children with LKS. A relative decrease in perfusion was found in the left frontal-temporal cortices of both patients as well as in the left and right parietal cortices of one patient with aphasia, without clinical epilepsy. The degree of regional cerebral perfusion impairment did not correlate with the severity of the clinical and EEG abnormalities, but the area of hypoperfusion was compatible with the speech area of the brain. Overall, although asymmetrical temporoparietal perfusion appears as a common finding in LKS, SPECT findings in LKS alone cannot elucidate the pathogenic features of the disorder in the brain. Here, we present two cases of LKS in which we investigated SPECT perfusion scans.

  13. Gene expression profile and functionality of ESC-derived Lin-ckit+Sca-1+ cells are distinct from Lin-ckit+Sca-1+ cells isolated from fetal liver or bone marrow.

    Directory of Open Access Journals (Sweden)

    Irina Fernandez

    Full Text Available In vitro bioreactor-based cultures are being extensively investigated for large-scale production of differentiated cells from embryonic stem cells (ESCs. However, it is unclear whether in vitro ESC-derived progenitors have similar gene expression profiles and functionalities as their in vivo counterparts. This is crucial in establishing the validity of ESC-derived cells as replacements for adult-isolated cells for clinical therapies. In this study, we compared the gene expression profiles of Lin-ckit+Sca-1+ (LKS cells generated in vitro from mouse ESCs using either static or bioreactor-based cultures, with that of native LKS cells isolated from mouse fetal liver (FL or bone marrow (BM. We found that in vitro-generated LKS cells were more similar to FL- than to BM LKS cells in gene expression. Further, when compared to cells derived from bioreactor cultures, static culture-derived LKS cells showed fewer differentially expressed genes relative to both in vivo LKS populations. Overall, the expression of hematopoietic genes was lower in ESC-derived LKS cells compared to cells from BM and FL, while the levels of non-hematopoietic genes were up-regulated. In order to determine if these molecular profiles correlated with functionality, we evaluated ESC-derived LKS cells for in vitro hematopoietic-differentiation and colony formation (CFU assay. Although static culture-generated cells failed to form any colonies, they did differentiate into CD11c+ and B220+ cells indicating some hematopoietic potential. In contrast, bioreactor-derived LKS cells, when differentiated under the same conditions failed to produce any B220+ or CD11c+ cells and did not form colonies, indicating that these cells are not hematopoietic progenitors. We conclude that in vitro culture conditions significantly affect the transcriptome and functionality of ESC-derived LKS cells and although in vitro differentiated LKS cells were lineage negative and expressed both ckit and Sca-1

    2016-12-01

    Full Text Available This paper addresses Landau–Kleffner syndrome (LKS, a childhood aphasia, from the perspective of I-language and the critical period for first language acquisition. LKS involves a language disorder and behavioral disturbances resembling autistic spectrum disorders due to electroencephalographic abnormalities with continuous spike-and-waves during sleep over the temporal regions. Comparing LKS with other childhood syndromes, the architecture of language is explored through elucidating the linguistic mechanisms behind the language disorder in LKS on the basis of Hickok & Poeppel’s (2007 dual-stream model of speech processing. It is claimed that early onset LKS provides further support for the critical period for first language acquisition and modularity of mind (the faculty of language, and that verbal auditory input during the critical period is most crucial for language recovery and development in LKS. Considering that electroencephalographic abnormalities affect cognitive/motor functions, ameliorating neural dysfunction in the affected brain areas with proper application of trans-cranial direct current stimulation is recommended.

    Free, M. P.; Angell, J. K.; Durre, I.; Klein, S.; Lanzante, J.; Lawrimore, J.; Peterson, T.; Seidel, D.

    2002-05-01

    The objective of NOAA's RATPAC project is to develop climate-quality global, hemispheric and zonal upper-air temperature time series from the NCDC radiosonde database. Lanzante, Klein and Seidel (LKS) have produced an 87-station adjusted radiosonde dataset using a multifactor expert decision approach. Our goal is to extend this dataset spatially and temporally and to provide a method to update it routinely at NCDC. Since the LKS adjustment method is too labor-intensive for these purposes, we are investigating a first-difference method (Peterson et al., 1998) and an automated version of the LKS method. The first difference method (FD) can be used to combine large numbers of time series into spatial means, but also introduces a random error in the resulting large-scale averages. If the portions of the time series with suspect continuity are withheld from the calculations, it has the potential to reconstruct the real variability without the effects of the discontinuities. However, tests of FD on unadjusted radiosonde data and on reanalysis temperature data suggest that it must be used with caution when the number of stations is low and the number of data gaps is high. Because of these problems with the first difference approach, we are also considering an automated version of the LKS adjustment method using statistical change points, day-night temperature difference series, relationships between changes in adjacent atmospheric levels, and station histories to identify inhomogeneities in the temperature data.

  9. The assessment of auditory function in CSWS: lessons from long-term outcome.

    Science.gov (United States)

    Metz-Lutz, Marie-Noëlle

    2009-08-01

    In Landau-Kleffner syndrome (LKS), the prominent and often first symptom is auditory verbal agnosia, which may affect nonverbal sounds. It was early suggested that the subsequent decline of speech expression might result from defective auditory analysis of the patient's own speech. Indeed, despite normal hearing levels, the children behave as if they were deaf, and very rapidly speech expression deteriorates and leads to the receptive aphasia typical of LKS. The association of auditory agnosia more or less restricted to speech with severe language decay prompted numerous studies aimed at specifying the defect in auditory processing and its pathophysiology. Long-term follow-up studies have addressed the issue of the outcome of verbal auditory processing and the development of verbal working memory capacities following the deprivation of phonologic input during the critical period of language development. Based on a review of neurophysiologic and neuropsychological studies of auditory and phonologic disorders published these last 20 years, we discuss the association of verbal agnosia and speech production decay, and try to explain the phonologic working memory deficit in the late outcome of LKS within the Hickok and Poeppel dual-stream model of speech processing.

    A boy, aged 2 1/2 yr, experienced sudden deterioration of speech and language abilities. He saw multiple medical professionals across 2 yr. By almost 5 yr, his vocabulary diminished from 50 words to 4, and he was referred to our speech and hearing center. The purpose of this study was to heighten awareness of Landau-Kleffner syndrome (LKS) and emphasize the importance of an objective test battery that includes serial auditory-evoked potentials (AEPs) to audiologists who often are on the front lines of diagnosis and treatment delivery when faced with a child experiencing unexplained loss of the use of speech and language. Clinical report. Interview revealed a family history of seizure disorder. Normal social behaviors were observed. Acoustic reflexes and otoacoustic emissions were consistent with normal peripheral auditory function. The child could not complete behavioral audiometric testing or auditory processing tests, so serial AEPs were used to examine central nervous system function. Normal auditory brainstem responses, a replicable Na and absent Pa of the middle latency responses, and abnormal slow cortical potentials suggested dysfunction of auditory processing at the cortical level. The child was referred to a neurologist, who confirmed LKS. At age 7 1/2 yr, after 2 1/2 yr of antiepileptic medications, electroencephalographic (EEG) and audiometric measures normalized. Presently, the child communicates manually with limited use of oral information. Audiologists often are one of the first professionals to assess children with loss of speech and language of unknown origin. Objective, noninvasive, serial AEPs are a simple and valuable addition to the central audiometric test battery when evaluating a child with speech and language regression. The inclusion of these tests will markedly increase the chance for early and accurate referral, diagnosis, and monitoring of a child with LKS which is imperative for a positive prognosis.

According to Financial Service Authority, most of financing of Syariah Banking is for the Micro, Small, Medium Enterprises that is very important for the nation economy, because it is engaged in the real sector of economy. And the other characters of the Micro, Small, medium enterprises in Indonesia are holding the honesty ethics and resistante to the crisis. They are the strengths of UMKM which must be considered to make the decision by the government or the Financial Institutions. Lembaga Keuangan Syariah (LKS berarti badan yang bergerak di bidang keuangan yang dilandaskan pada ajaran Islam yang bersumber pada al Qur’an dan As Sunnah. Praktek ini sudah terdapat pada sejarah awal Islam, dan asas moralitas Islam dikembangkan dalam bentuk LKS. Sehingga, tujuan dari LKS tidak semata Profit Oriented, melainkan terdapat unsur-unsur keislaman dan kemanusiaan di dalamnya. Lembaga Keuangan syariah sebagian besar pembiayaannya diperuntukkan kepada sektor usaha, dan punya kemampuan untuk menjangkau usaha mikro, Sesuatu yang jarang dilakukan oleh pihak perbankan konvensional. Pembiayaan kepada UMKM ini tidak lepas juga dari pengaruh Grameen Bank sebelumnya, yang telah berdiri sejak medio 1970-an. Pembiayaan

    The left kidney (LK) is preferred by transplant surgeons, because its vein is always of good length and has a thick wall that enables safe suturing. On the other hand, the right renal vein is generally shorter and thinner walled, and well known for its technical difficulty during venous anastomosis, and can result in graft loss. We examined our living (LD) and deceased donor (DD) recipient data and compared the incidence of technical graft loss and early graft function in right and left kidneys. A cohort of 58 adult and pediatric recipients received an LD or DD kidney between January 2015 and December 2016. The donor and recipient data were retrieved and retrospectively analyzed. Technical graft loss was defined as graft thrombosis within the 7 days after transplant. Right kidneys (RKs) were not a risk factor for technical graft loss, and no graft was lost for technical reasons in either LD or DD transplants. Early graft function in LK and RKs was also comparable in the LD cohort, and there were no LKs in the DD cohort. Based on our data, the use of RKs was not a risk factor for technical graft loss and early graft function was comparable to LKs.

      We report three cases of Landau-Kleffner syndrome (LKS) in children (two females, one male) in whom diagnosis was delayed because the sleep electroencephalography (EEG) was initially normal.   Case histories including EEG, positron emission tomography findings, and long-term outcome were reviewed.   Auditory agnosia occurred between the age of 2 years and 3 years 6 months, after a period of normal language development. Initial awake and sleep EEG, recorded weeks to months after the onset of language regression, during a nap period in two cases and during a full night of sleep in the third case, was normal. Repeat EEG between 2 months and 2 years later showed epileptiform discharges during wakefulness and strongly activated by sleep, with a pattern of continuous spike-waves during slow-wave sleep in two patients. Patients were diagnosed with LKS and treated with various antiepileptic regimens, including corticosteroids. One patient in whom EEG became normal on hydrocortisone is making significant recovery. The other two patients did not exhibit a sustained response to treatment and remained severely impaired.   Sleep EEG may be normal in the early phase of acquired auditory agnosia. EEG should be repeated frequently in individuals in whom a firm clinical diagnosis is made to facilitate early treatment. © The Authors.

    Thermodynamic studies of (Li x K 1-x ) 2 SO 4 , LKS, mixed crystals have been made in the concentration range (x=0.1,0.2,...,x=0.5). The thermal behavior has been investigated by differential thermal analysis, DTA, and differential scanning calorimeter, DSC, in the vicinity of high temperature phases. Also, the effect of the mixed neutron field of fast and thermal neutrons (10% of the reactor neutron pile is fast neutrons) on the thermal properties of mixed crystals was studied. The results showed a change in the transition temperature Tc, as well as the value of specific heat Cp at transition temperature, due to the change of stoichiometric ratio and radiation doses. The change of enthalpy and entropy of mixed crystals have been estimated numerically. The obtained small values of ΔS/R is characteristic of incommensurate phase transition as previously confirmed by the results of neutron diffraction technique. (author). 16 refs, 5 figs, 1 tab

This study reports the knowledge and experiences of staff members supporting disabled people living in community residential homes, as well as their perceived needs for information and support. Furthermore, the study aimed to reveal staff´s views on their possibilities to support service users´ wellbeing, participation and quality of life. Participants were twelve experienced staff members. Qualitative methods were used and data were collected through semi-structured interviews. The results of the study reveal that services provided in community residential homes for people with complex and severe impairments are not in line with human rights treaties, including the right to health. Further, it does not mirror the social approach to disability which today is the focus of policy frameworks. The staff were positive toward service users, tried to do their best but lacked resources. Their knowledge of service user´s health-related needs was scarce and little was done to prevent further impairments or increasing health problems. Staff reported lack of human resources, high staff turnover and lack of information, training and support. Recent governmental changes, provide possibilities for revised emphasis in the service provided, on cooperation between different sectors as well as for the development of transdisciplinary services.Aðstoðarfólk á heimilum fólks með fjölþættar skerðingar er mikilvægur hlekkur í lífi þess og lykill að samskiptum, lífsgæðum og þátttöku.

    The spleen tyrosine kinase (SYK) was identified as an oncogenic driver in a broad spectrum of hematologic malignancies. The in vivo comparison of three SYK containing oncogenes, SYK wt , TEL–SYK and IL-2-inducible T-cell kinase (ITK)-SYK revealed a general myeloexpansion and the establishment of three different hematologic (pre)diseases. SYK wt enhanced the myeloid and T-cell compartment, without leukemia/lymphoma development. ITK–SYK caused lethal T-cell lymphomas and the cytoplasmic TEL–SYK fusion induced an acute panmyelosis with myelofibrosis-type acute myeloid leukemia (AML) with up to 50% immature megakaryoblasts infiltrating bone marrow, spleen and liver, additional MPN features (myelofibrosis and granulocyte expansion) and MDS stigmata with megakaryocytic and erythroid dysplasia. LKS cells were reduced and all subsets (LT/ST/MPP) showed reduced proliferation rates. SYK inhibitor treatment (R788) of diseased TEL–SYK mice reduced leukocytosis, spleen and liver infiltration, enhanced the hematocrit and prolonged survival time, but could not significantly reduce myelofibrosis. Stat5 was identified as a major downstream mediator of TEL–SYK in vitro as well as in vivo. Consequently, targeted deletion of Stat5 in vivo completely abrogated TEL–SYK-induced AML and myelofibrosis development, proving Stat5 as a major driver of SYK-induced transformation. Our experiments highlight the important role of SYK in AML and myelofibrosis and prove SYK and STAT5 inhibitors as potent treatment options for those diseases

    Thermal Radiation Experiments Kit (TREK) based on data logger for physics learning media was developed. TREK will be used as a learning medium on the subject of Temperature and Heat to explain the concept of emissivity of a material in grade XI so that it can add variations of experiments which are commonly done such as thermal expansion, transfer of thermal energy (conduction, convection, and radiation), and specific heat capacity. DHT11 sensor is used to measure temperature and microcontroller Arduino-uno used as data logger. The object tested are in the form of coated glass thin films and aluminum with different colors. TREK comes with a user manual and student worksheet (LKS) to make it easier for teachers and students to use. TREK was developed using the ADDIE Development Model (Analyze, Design, Development, Implementation, and Evaluation). And validated by experts, physics teachers, and students. Validation instrument is a questionnaire with a five-item Likert response scale with reviewed aspect coverage: appropriate content and concepts, design, and user friendly. The results showed that TREK was excellent (experts 88.13%, science teachers 95.68%, and students 85.77%).

  7. JAK and MPL mutations in myeloid malignancies.

    Tefferi, Ayalew

    2008-03-01

    The Janus family of non-receptor tyrosine kinases (JAK1, JAK2, JAK3 and tyrosine kinase 2) transduces signals downstream of type I and II cytokine receptors via signal transducers and activators of transcription (STATs). JAK3 is important in lymphoid and JAK2 in myeloid cell proliferation and differentiation. The thrombopoietin receptor MPL is one of several JAK2 cognate receptors and is essential for myelopoiesis in general and megakaryopoiesis in particular. Germline loss-of-function (LOF) JAK3 and MPL mutations cause severe combined immunodeficiency and congenital amegakaryocytic thrombocytopenia, respectively. Germline gain-of-function (GOF) MPL mutation (MPLS505N) causes familial thrombocytosis. Somatic JAK3 (e.g. JAK3A572V, JAK3V722I, JAK3P132T) and fusion JAK2 (e.g. ETV6-JAK2, PCM1-JAK2, BCR-JAK2) mutations have respectively been described in acute megakaryocytic leukemia and acute leukemia/chronic myeloid malignancies. However, current attention is focused on JAK2 (e.g. JAK2V617F, JAK2 exon 12 mutations) and MPL (e.g. MPLW515L/K/S, MPLS505N) mutations associated with myeloproliferative neoplasms (MPNs). A JAK2 mutation, primarily JAK2V617F, is invariably associated with polycythemia vera (PV). The latter mutation also occurs in the majority of patients with essential thrombocythemia (ET) or primary myelofibrosis (PMF). MPL mutational frequency in MPNs is substantially less (<10%). In general, despite a certain degree of genotype - phenotype correlations, the prognostic relevance of harbouring one of these mutations, or their allele burden when present, remains dubious. Regardless, based on the logical assumption that amplified JAK-STAT signalling is central to the pathogenesis of PV, ET and PMF, several anti-JAK2 tyrosine kinase inhibitors have been developed and are currently being tested in humans with these disorders.

    Any intraoperative rotational malalignment during intramedullary nailing (IMN) of femoral shaft fractures will become permanent. We hypothesized that rotational malalignment of the femur and its compensatory biomechanics may induce problems in the hip, knee, patellofemoral and ankle joints. We purposed to clarify the influence of a femoral rotational malalignment of ≥10° on daily activities. Twenty-four femoral shaft fracture patients treated with closed antegrade IMN were included. At last follow-up, to reveal any rotational malalignment, computerized tomography (CT) scans of both femurs (injured and uninjured sides) were examined. The patient groups with or without CT-detected true rotational malalignment ≥10° were compared with respect to the activity scores. Ten of the 24 patients (41.7%) had a CT-detected true rotational malalignment of ≥10° compared with the unaffected side. The AOFAS scores were 100.00 for all of the patients. LKS, WOMAC knee, and WOMAC hip scores were significantly decreased in the patients with rotational malalignment compared to those without. Patients without rotational malalignment tolerated climbing stairs significantly better than those with rotational malalignment. Patients who could not tolerate climbing stairs were consistently complaining of anterior knee pain. A femoral rotational malalignment of ≥10° is symptomatic for the patients, and the hip, knee, and patellofemoral joints were affected. Because of the possibly altered joint loadings and biomechanics, these could render patients prone to degenerative joint disease. In addition, due to the high rates of rotational malalignment after femoral shaft fracture and consequent malpractice claims, it is important for surgeons to be more aware of rotational alignment during surgery.

  11. Suppression of cytochrome p450 reductase enhances long-term hematopoietic stem cell repopulation efficiency in mice.

    Full Text Available BACKGROUND: Bone marrow microenvironment (niche plays essential roles in the fate of hematopoietic stem cells (HSCs. Intracellular and extracellular redox metabolic microenvironment is one of the critical factors for the maintenance of the niche. Cytochrome P450 reductase (CPR is an obligate electron donor to all microsomal cytochrome P450 enzymes (P450 or CYP, and contributes to the redox metabolic process. However, its role in maintaining HSCs is unknown. OBJECTIVE: To examine the effects of low CPR expression on HSCs function using a mouse model of globally suppressed Cpr gene expression (Cpr Low, CL mice. METHODS: Hematopoietic cell subpopulations in bone marrow (BM and peripheral blood (PB from WT and CL mice were examined for their repopulation and differentiation ability upon BM competitive transplantation and enriched HSC (LKS(+ transplantation. Effects of low CPR expression on hematopoiesis were examined by transplanting normal BM cells into CL recipients. Reactive oxygen species (ROS, cell cycle, and apoptosis in CL mice were analyzed by flow cytometry for DCF-DA fluorescence intensity, Ki67 protein, and Annexin-V, respectively. RESULTS: The levels of ROS in BM cells, HPCs and HSCs were comparable between CL and WT mice. In comparison to WT mice, the number of LT-HSCs or ST-HSCs was lower in CL mice while CMPs, GMPs and MEPs in CL mice were higher than that in WT control. Competitive transplantation assay revealed enhanced repopulation capacity of HSCs with low CPR expression, but no difference in differentiation potential upon in vitro experiments. Furthermore, lymphoid differentiation of donor cells decreased while their myeloid differentiation increased under CL microenvironment although the overall level of donor hematopoietic repopulation was not significantly altered. CONCLUSIONS: Our studies demonstrate that suppressing CPR expression enhances the repopulation efficiency of HSCs and a low CPR expression microenvironment favors

The result of the literature study showed that comic used as media in learning Physics was very effective as learning media and attractive to be read. One of the supporting factors of this success in improving the students’ multiple intelligences was the integration of art and craft activities in the science learning process. Moreover, the theory of multiple intelligences accomodated students with various way of learning thinking. The developed training model in this study consisted of five stages that were orientation, presentation, structured excersice, guided excersice and individual excersice. In each Science class, the learning process was always started with the elicitation of students’ prior knowledge. Then each student got one comic to be read. After the reading session, the teacher asked them about the contents of the comics either classically or individually. In the next step the students were invited to observe the demonstration done by the teacher only if the instruments or materials were not safe for them, (e.g hot water. Nevertheless, if they were safe enough for the students, they were allowed to do the experiment by themselves. Students’ worksheets (LKS were done by the students in group to develop their interpersonal and verbal-linguistic intelligences. Based on observation during experiments and drawing activities, the students’ visual-spatial intelligences were developed. Every learning process was always ended with knowledge test individually which would be discussed later. The study concluded that: 1 the training model improved PGSD students’ skills in developing comic as teaching media, 2 comics are proven to improve the elementary school students’ motivation in learning science, 3 comic enhanced elementary school students’ understanding in science knowledge which was indicated by the achievement of the students’ test score (85

    heilbrigðiskerfið hlúir að útlendingum búsettum á Íslandi. Erlendar rannsóknir gefa til kynna að ekki sé tekið nægjanlegt tillit til menningarbundinna viðhorfa, t.a.m. í samræmi jafnræðisreglu stjórnsýslulaga. Tilgangur rannsóknarinnar var að kanna viðhorf, hefðir og væntingar erlendra kvenna til barneignarferlisins ásamt reynslu þeirra af barneignarferlinu og barneignarþjónustunni hér á landi. Markmiðið var að afla þekkingar sem gæti nýst við mótun menningarhæfrar barneignarþjónustu fyrir erlendar barnshafandi konur. Rannsóknin var eigindleg þar sem hugtakið menningarhæfni og hugmyndafræði þjónandi forystu voru lögð til grundvallar með viðtölum við sjö erlendar konur, fyrir og eftir fæðingu barna þeirra hér á landi. Niðurstöður rannsóknarinnar endurspeglast í þremur þemum sem snerta þarfir, væntingar og reynslu erlendra kvenna af barneignarþjónustu hér á landi: Skortur á félagslegum stuðningi; Viðmót starfsfólks; tjáskipti og traust; Fræðsla og árekstrar við kerfið. Þemun vísa til fjölbreyttra samskipta við umönnunaraðila og reynslu af þjónustunni. Almenn ánægja var með viðmót fagfólks en vísbendingar voru um að bæta megi fræðslu og upplýsingagjöf, túlkaþjónustu og stuðning. Samfelld ljósmæðraþjónusta og þjónandi forysta virðist henta vel og vera vænleg leið til að efla menningarhæfa barneignarþjónustu. Framtíðarverkefni innan barnseignarþjónustunnar eru samskipti sem efla heilsulæsi og sjálfstraust kvenna sem eru af erlendu bergi brotnar. Niðurstöður samræmast erlendum rannsóknum og eru mikilvægt framlag til þekkingarþróunar á þverfræðilegum grunni fyrir skipulag menningarhæfrar barneignarþjónustu sem nýtist heilbrigðis- og velferðarþjónustu.

    Full Text Available Abstract in English is unavailable.Hér á eftir er rakinn aðdragandi þeirra breytinga sem gerðar voru á fyrningarreglum almennra hegningarlaga vegna kynferðisbrota gegn börnum síðasta vor með lögum nr. 61/2007. Ein þeirra fól í sér að alvarleg kynferðisbrot gegn börnum fyrnast nú ekki. Frá refsipólitísku og afbrotafræðilegu sjónarmiði er þessi breyting athyglisverð. Í henni felst frávik frá þeirri stefnumörkun löggjafans til langs tíma að fækka ófyrnanlegum brotum og að eingöngu þau brot sem geta varðað ævilöngu fangelsi skuli vera ófyrnanleg. Ekkert þeirra kynferðisbrota sem breytingin tekur til getur varðað svo þungri refsingu. Breytingin átti sér langan aðdraganda, þótt svo mætti virðast af ferli málsins á Alþingi vorið 2007 að hana hafi borið brátt að. Fjöldi frumvarpa sem að þessu snúa hefur verið lagður fram á Alþingi síðari ár og umræður á þeim vettvangi um eðli kynferðisbrota gegn börnum, rannsóknir fagfólks og reynslusögur fórnarlamba kynferðisbrota og lýsingar þeirra á afleiðingum brotanna á lífshlaup sitt, skýra þetta frávik frá meginstefnu löggjafans að verulegu leyti. Ákvörðunin var tekin eftir mikil skoðanaskipti og umræður. Aðdragandinn sýnir að breytingin byggist á sérstöku eðli þessara brota og felur í sér áherslu á alvarlegar og langvarandi afleiðingar þeirra fyrir fórnarlömbin, sem taldar eru vega þyngra en almenn rök að baki fyrningarreglum um réttarstöðu brotamanns, erfiðleika við rannsókn brotanna og sönnun. Á hinn bóginn má vera að vegna þessara vandkvæða feli breytingin fyrst og fremst í sér táknræna viðurkenningu löggjafans á alvarleika brotanna, fremur en að hún eigi eftir að hafa mikla raunhæfa þýðingu.

    Way. I obtain the mass distribution and the light distribution of these stars. I ! find that the flattening of the stellar distribution increases outside 70''. This indicates that inside a nearly spherical nuclear cluster dominates and that the surrounding light belongs mostly to the nuclear disk. I dissect the light in two components and obtain for the nuclear cluster L_Ks=2.7*10^7 L_sun. I obtain proper motions for more than 10000 stars and radial velocities for more than 2400 stars. Using Jeans modeling I combine velocities and the radial profile to obtain within 100'' (4 pc) a mass of 6.02*10^6 M_sun and a total nuclear cluster mass of 12.88*10^6 M_sun. The Jeans modeling and various other evidence weakly favor a core in the extended mass compared to a cusp. The old star light shows a similar core. The mass to light ratio of the old stars of the nuclear cluster is consistent with the usual initial mass function in the Galaxy. This suggests that most stars in GC formed in the usual way, in a mode different from the origin of the youngest stars there.
