Objective: To evaluate the distribution and characteristics of peripheral nerve abnormalities in chronic inflammatory demyelinating polyneuropathy (CIDP) using magnetic resonance neurography (MRN) and to examine the diagnostic efficiency. Materials and Methods: Thirty-one CIDP patients and 21 controls underwent MR scans. Three-dimensional sampling perfections with application-optimized contrasts using different flip-angle evolutions and T1-/T2- weighted turbo spin-echo sequences were performed for neurography of the brachial and lumbosacral (LS) plexus and cauda equina, respectively. Clinical data and scores of the inflammatory Rasch-built overall disability scale (I-RODS) in CIDP were obtained. Results: The bilateral extracranial vagus (n = 11), trigeminal (n = 12), and intercostal nerves (n = 10) were hypertrophic. Plexus hypertrophies were observed in the brachial plexus of 19 patients (61.3%) and in the LS plexus of 25 patients (80.6%). Patterns of hypertrophy included uniform hypertrophy (17 [54.8%] brachial plexuses and 21 [67.7%] LS plexuses), and multifocal fusiform hypertrophy (2 [6.5%] brachial plexuses and 4 [12.9%] LS plexuses) was present. Enlarged and/or contrast-enhanced cauda equina was found in 3 (9.7%) and 13 (41.9%) patients, respectively. Diameters of the brachial and LS nerve roots were significantly larger in CIDP than in controls (p < 0.001). The largest AUC was obtained for the L5 nerve. There were no significant differences in the course duration, I-RODS score, or diameter between patients with and without hypertrophy. Conclusion: MRN is useful for the assessment of distribution and characteristics of the peripheral nerves in CIDP. Compared to other regions, LS plexus neurography is more sensitive for CIDP.

This study is aimed at contributing to the future development of Home Economics Education Department by suggesting basic data of TQM(Total Qualify Management) for evaluating TQM of Home Economics Education Departmeut in education colleges. A survey was conducted involving all junior(3rd year) students of Home Economics Education Department in education colleges either by making a visit to 3 different schools or by sending it in the mail to 10 different schools. Responding answer-sheets, 302 copies(88.3%) out of 342 copies in total were returned. Finally, we used 285 copies(83.3%) as data for analysis. The results of this study are as follows: In terms of Professional Qualification of Home Economics Teachers, the students had passion for their Home Economics Education and also had a great pride and mission to be future Home Economics teachers. However, their ability proved to be poor and low in presenting a vision for Home Economics, in conducting extra-curricular activities, and the computer skills. In the case of college students, their satisfaction showed an average point 3.15 on a scale of 5. Those students who entered school voluntarily or those who hoped for re-entrance showed more satisfaction than those who entered school with good academic records or those who do not hope for re-entrance into school. In terms of professors' leadership, Students are perceived to choose 'Transactional Leadership' instead of 'Transformational Leadership'. Students', who have higher satisfaction and hopes for re-entrance, perception level about their professors' leadership style showed higher satisfaction than average. The students empowerment level showed average point 3.52, which is considered relatively high. Students at the college where professors majored in Home Economics Education are employed showed higher empowerment level than students at the college with professors who did not major in Home Economics Education. The result of evaluating general demand for renovating of Home Economics Education Dept. showed that: they perceived the "Teacher Education Course" of Home Economics Education Dept. as in need of cultivating practical skills in secondary school. They also said, "Teaching Method" is in great need of renovation. In the case of teaching method, they preferred laboratory work, and practical training. In earning credits, they emphasized the importance of faithfully completing the "Study of Content". For the Subject Matter Education, they required a training course to be set up in the secondary school. Finally they claimed that the teachers and students need to take the initiative in developing a Curriculum of Home Economics Education Dept. Based on the findings mentioned above, I would like to suggest further research on how to adopt and evaluate TQM in Home Economics Education, and faculty-centered evaluation methods. I also would like to suggest to vitalize quality research through the form of narrative research.

The current study was performed to investigate the magnitude of exercise-induced muscle damage (EIMD) after downhill running (DR) of different intensities and to examine the availability of muscle echo intensity as biomarkers to detect regional damage within quadriceps muscle group (QG) following DR. Healthy college-age men (n=11) were experienced twice DR sessions [$50%HR_{max}$ DR, LDR; $70%HR_{max}$ DR, HDR] separated by a 2-week wash-out period with the random order. After DR, severity of EIMD according to exercise intensity were determined by serum creatine kinase (CK) activity, muscle tenderness, and neuromuscular function indicators such as a maximal voluntary isometric contraction (MVIC) and range of motion (ROM). Transvaginal B-mode imaging had been employed to evaluate regional muscle echo intensity within QG [rectus femoris, RF; vastus lateralis, VL; vastus medialis, VM; vastus intermedius, VI]. After both DR sessions, changes in serum CK activity and muscle tenderness have tended to more increase in HDR compared to those of LDR. There was a significant interaction effect between exercise intensity during DR and the time course of serum CK activity(p<.05). However, there were no statistical differences between sessions in muscle tenderness. The time course of changes in the neuromuscular functions after DR were similar to those of regional muscle echo intensity regardless exercise intensity. Although neuromuscular function showed to decline in HDR more than those of LDR after DR, no statistical differences between sessions. In contrast, there were significant interaction effects between sessions and time course of changes in RF and VL muscle echo intensity(p<.01), but not shown in those of VI and VM. These results indicated that each muscles within the QG show different response profiles for EIMD during DR, exercise intensity influences on these responses as well. In particular, current findings suggested that muscle echo intensity derived from ultrasound imaging is capable of detecting regional muscle damage in QG following DR.

The purpose of this study is to explore evaluation criteria that pre-service elementary teachers employ as they evaluate and select models to explain electric circuits. Thirty junior students in a university of education have participated in the study as a part of the science education course in which they were enrolled. The lessons for the participants have been organized as a cyclic sequence of different modeling pedagogies including the expressive, experimental, and evaluative modeling. The pre-service teachers have been given five electric circuits in order and asked to create models and further develop them through peer discussion. Their modeling activities have been video- or audio-recorded, and the recordings and their transcripts have been analyzed using a framework of model evaluation criteria. It reveals that the types and frequencies of evaluation criteria used are different between situations of model development and model selection. While empirical and theoretical criteria have been used dominantly in both situations, more various criteria have been employed in the situation where the pre-service teachers selected one model among alternatives. Implications for science education and science education research have been suggested.

Objective: This paper introduces the regulatory oversight approaches and issues to consider in the course of safety culture oversight model development in the nuclear field. Common understanding on regulatory oversight and present practices of international communities are briefly reviewed. The nuclear safety culture oversight model of Korea is explained focusing on the development of safety culture definition and components, and their basic meanings. Oversight components are identified to represent the multiple human and organizational elements which can affect and reinforce elements of defense in depth system for nuclear safety. Result of validation study on safety culture components is briefly introduced too. Finally, the results of the application of the model are presented to show its effectiveness and feasibility. Background: The oversight of nuclear licensee's safety culture has been an important regulatory issue in the international community of nuclear safety regulation. Concurrent with the significant events that started to occur in the early 2000s and that had implications about safety culture of the operating organizations, it has been natural for regulators to pay attention to appropriate methods and even philosophy for intervening the licensee's safety culture. Although safety culture has been emphasized for last 30 years as a prerequisite to ensure high level of nuclear safety, it has not been of regulatory scope and has a unique dilemma between external oversight and the voluntary nature of culture. Safety culture oversight is a new regulatory challenge that needs to be approached taking into consideration of the uncontrollable aspects of cultural changes and the impacts on licensee's safety culture. Although researchers and industrial practitioners still struggle with measuring, evaluating, managing and changing safety culture, it was recognized that efforts to observe and influence licensees' safety culture should not be delayed. Method: Safety culture components which regulatory oversight will have to focus on are developed by benchmarking the concept of physical barriers and introducing the defense in depth philosophy into organizational system. Therefore, this paper begins with review of international regulatory oversight approaches and issues associated with the regulatory oversight of safety culture, followed by the development of oversight model. The validity of the model was verified by statistical analysis with the survey result obtained from survey administration to NPP employees in Korea. The developed safety culture oversight model and components were used in the "safety culture inspection" activities of the Korean regulatory body. Results: The developed safety culture model was confirmed to be valid in terms of content, construct and criterion validity. And the actual applicability in the nuclear operating organization was verified after series of pilot "safety culture inspection" activities. Conclusion: The application of the nuclear safety culture oversight model to operating organization of NPPs showed promising results for regulatory tools required for the organizations to improve their safety culture. Application: The developed oversight model and components might be used in the inspection activities and regulatory oversight of NPP operating organization's safety culture.

The study was done to improve the job training course for Community Health Practioners (CHPs) by evaluating the level of help that the training provided to the CHPs in carrying out their work and to analyze the management activities of the CHPs in order to develop a more effective CHP training program. The methodologies used in the study were a questionnaire survey. The survey results were analyzed using SPSS Windows. The study results are as follows. 1. The total average level of help from the job training(Theory. Practice and Field Practice) for carrying out the CHP work was found to be $3.04\pm.53$ (of a possible 4), which indicates a high level of help. The average for clinical practices was $3.16\pm.60$. for theory. $3.11\pm.40$ and for field practice. $2.84\pm.60$. 2. For the theory content of the job training courses. the help level was low in the area of mother and child health management/family planning with an average of $2.65\pm.62$ and in the area of health information system development with an average of $2.62\pm.83$. The reason for these deficiencies were. in order of frequency. few opportunities to apply learning. training content that was inadequate. training methodologies which were incongruent with content. improper training items and insufficient class hours. For the practice. the clinical work in rehabilitation/orthopedics departments and in ENT/Opthalmology departments had averages of $2.96\pm.86$ and $2.97\pm.80$ respectively. This low level resulted from the lack of direct experience. lack of sincerity during the practice time. lack of practice guidance. insufficient time and lack of practice equipment. in that order. For the field practice. the delivery management averaged $2.06\pm.90$ as the lowest help level. In this case 68% of respondents replied that there were no relevant reasons for this deficiency. 21% responsed that there was a lack of direct experience, 7%, a lack of practice guidance and 4.8%, insufficient time. 3. There were significant differences for several demographic variables when comparing the help level of the clinical courses (practice and Field Practice). A higher help level was reported by older nurses as compared to younger ones, experienced nurses as compared to scholarship nurses, and married over single. Also for nurses who had finished more other programs and were qualified or licensed in several areas the level was high. Although it was not statistically significant the level was higher if the work area was in a rural county, not a city, and if one had more recently completed the job training(P<,05). 4. Of the respondents 58.6% replies stated the period of job training for the CHP was adequate, but 51.7% reported that the period for theory courses was too short while an other 48.3% responded that it was sufficient. For practice locations, 50% responsed that it was good to practice in medical institutions(primary, secondary and tertiary) at the same time. While 48.3% agreed that doing theory and practice simultaneously was good, and 56.9% agreed that field practice should be done after completing theory and practice training. Hence, the development of new field practice guidelines suitable for changing environments of health management are required in place of the existing ones which were considered low in help level to the practical work of the CHPs.

Recently, 'students who gave up mathematics' became social problems. The need for systematic support for spreading and seating mathematics clinics was recognized. The mathematics clinic emphasizes the change of the affective aspects by constantly meeting the students and listening to the worries of the students. It is also a program that guides students in the future to see mathematics in a positive way. However, at school, mathematics clinics are operated in various forms at the discretion of teachers. Therefore, it is difficult to confirm whether the purpose of the mathematics clinic is being achieved properly. It is necessary to prepare a plan that can act as a guideline to check the necessary basic items for the runs of the math clinic and to check the necessary parts in the course of runs The purpose of this study is to develop a model for evaluating mathematics clinic programs which can be a guideline for the operation of mathematics clinic programs in a systematic way and to reduce the confusion of operation of mathematics clinics at the schools. We expect that this evaluation model could provide a direction for the operation of a math clinic.

This study was carried out to examine the actual condition of health promotion program through oriental medicine in the health center and to provide basic data to develop proper policy of oriental medical health promotion program for the community people. The data were collected from 26 health centers which have been implementing the oriental medical health promotion program, using selfadministered questionnaire for two weeks from 1 October to 15 October 2006. The results are as follows : Generally, the respondents have the positive views on the level of budget and facilities/equipments of the oriental medical health promotion program in health center. However, they have the negative views on the level of manpower and education/training of the program. And also more than 70% of the respondents have the negative opinion on capabilities of formulating and evaluating the oriental medical health promotion program. The respondents indicated that there was the lack of coordination between the oriental medical health promotion program and existing health promotion in health center, and that low rate of utilizing community resources. With regard to the method of selecting the target group for the program, there are differences according to the each program. Many programs tended to select the target group not through the criteria of life-course and illness group but through the efficiency of selecting group. And many programs such as stroke prevention program, constitutional medicine program, oriental medical prenatal program, oriental medical prenatal and postnatal program, oriental medical child care program are mainly composed of the development of educational program and lecture. Regarding the number of the present oriental medical health promotion programs, around 65% of respondents answered that the number of the programs was many and thus they needed to decrease to the proper level. And with regard to the priority of the need, effectiveness and the satisfaction for each programs, on the whole, Qui gong program, stroke prevention program, area-specialty program and oriental medical home visiting program have high score. In particular, oriental medical quit-smoking program has lowest score. From these results, it requires to develop and improve the oriental medical health promotion program in health center considering the need and characteristics of community.

In this paper, the activities for scientifically-gifted high school students in the 2006 International Young Physicists' Tournament were analyzed, from the perspective of the social aspects of creativity. To understand this, the process by which the activities were similar to the system model of creativity developed by Csikszen-tmihalyi were analyzed. Our aim was to elicit the educational implications of cooperative science problem solving skills and to discuss the results from their social perspective. It was found that participants interacted consistently with peers, teachers, and the culture that was developed during the course of the tournament. This was found to be very similar to the way in which novel knowledge in the system model of creativity is produced. In the tournament, the juries' assessment was based on students' presentations, discussions, and reviews. This was also very similar to how novel knowledge in the model is selected. Solving problems cooperatively and evaluating the results through group discussion are well reflected the social aspects of creativity. Due to the fact that such tournaments for scientifically-gifted elementary students are rapidly increasing in popularity, such activities will increasingly become more important. It is necessary, therefore, to study the social aspects of creativity for the gifted in elementary and middle school.
