The aim of this survey is to investigate the occupational musculoskeletal disease and stress levels of restaurant cooks and to provide a basic data of programs in order to prevent occupational diseases. A questionnaire survey was conducted on 220 subjects in Gangwon province. The results show that there was no significant difference in the degree of occupational musculoskeletal disease between male cooks and female cooks. However, western cuisine cooks were more likely to have a higher degree of occupational musculoskeletal disease than other cuisine cooks and showed a higher degree of occupational stress from work overload as well as irregular meal stresses. Cooks aged from 30 to 40 years showed a higher level of occupational musculoskeletal disease in the neck, shoulder, and hand/wrist compared to those in other age groups. The job tenure was related to the degree of musculoskeletal disease in knee. Additionally, the hours of working per day were statistically significantly related to musculoskeletal disease in the knee and to the occupational stress levels in irregular meals stress. The findings of this study suggest that it is essential to design customized education for cooks to lessen their occupational musculoskeletal diseases and stresses in order to ensure the health and safety of the culinary workers.

이정실 한국식품영양학회 2002 韓國食品營養學會誌 Vol.15 No.3
The purpose of this study was analyzed the general factors that influence school dietitians' satisfaction from their regular duties, the current status of food distribution to students and the relationship between dietitians and their governing authorities. Dietitians of primary school had higher score on direct management and working career. High school dietitian had higher scores on consignment management, freedom in amount of food distribution and number of meals a day. The highest score was on the relationship with other coworkers and the lowest score was on the poor working environment and salary. In general, dietitians in all schools are not satisfied the working environment and salary. Depending upon the duty time, there were differences in the nature of their duties. There was also a significant difference in the nature of duties and the professionalism based on the average income. Even though they got paid less, they felt satisfaction because of the less working times. The amount of labor for those in primary schools was more than the one for dietitians in high schools. It is likely that they got more satisfied when other related people feel satisfied with their own things and duties based on the nature of the duties, discretion of duties, professionalism, relationship with other coworkers and participation in decision making process. It is to develop the nature of the duties for all the dietitians in order to launch the new and right ideas in meal plans for students. It is also to promote and uphold the professionalism and efficient management programs in association with the stable human resources. Assuming we will come up with a wide and broad nationwide survey, and further research shall be more reliable and objective than any others.
서울과 강원 일부지역 대학생들의 스트레스 정도가 식습관에 미치는 영향
이정실,Lee, Jeongsill 한국식품영양학회 2015 韓國食品營養學會誌 Vol.28 No.5
The purpose of this study is the examination of stress levels and the eating habits that are affected by stress, and the provision of basic nutritional education data for the improvement of the eating habits of students who have experienced stress-related nutritional problems. Using the BEPSI-K instruments, a questionnaire survey was administered to 327 student subjects (166 male and 161 female) in the areas of Seoul and Gangwon province. The subjects were classified into 3 groups (low-stress, medium-stress and high-stress), and 59 students (18%) belonged the high-stress group. The BMI readings of the Gangwon province students are significantly higher than those of the Seoul students. The survey results show that the lunch frequency and vegetable intake levels are lower in the high-stress group, whereas the intakes of hot spicy food is higher in this group; they also show that Gangwon province students had eating habits that are relatively undesirable compared with the Seoul students. There are significant differences between the Seoul students and Gangwon porvince students regarding residence type, household economic level, types of leisure activities and level of some stresses. The Gangwon province students ate occasionally breakfast, lunch and snacks, but their midnight snack consumption is relatively frequent compared with the Seoul students. The results of the survey indicate that the BEPSI-K score has a negative correlation with the following variables : sleeping time, economic level of household, degrees of satisfaction regarding appearance and academic achievements, lunch frequency and vegetable intakes. Desirable eating habits are essential for the maintenance of a favorable health status and for the stress-management of university students who need to be a healthy members of society in the near future. To facilitate the formation of desirable eating habits among university students, community-based nutritional assistance and appropriate nutritional education programs should be considered necessary.
Precocious Expression of Drosophila Rbp9 Inhibits Ovarian Germ Cell Proliferation
Jeongsil Kim-Ha,Kyoungsuk Jeong 한국분자세포생물학회 2004 Molecules and cells Vol.18 No.2
We previously reported that Rbp9 is expressed in the germarium region as soon as germ cells complete mitosis and form 16 interconnected cystocytes. Mutation of Rbp9 caused over-proliferation of cystocytes and generated an ovarian tumor phenotype. This led us to conclude that Rbp9 either inhibits cell proliferation or is required for cell differentiation. To examine the role of Rbp9, we over-expressed it ectopically in germline stem cells and early stage cystocytes that had not yet formed 16 cell clusters. The egg chambers of the newly eclosed transgenic flies looked normal. However, on day 12, most of the developing egg chambers had disappeared and only the germarium region remained. Staining of the Rbp9 over-expressing transgenic ovaries with mitosis markers revealed almost no mitotic divisions in the transgenic germaria. Further examination of these cystocytes with HTS [hu-li tai shao protein], which labels the fusome structure, revealed that the cells in the germarium region consisted of stem cells and cystocytes that had not yet completed four mitotic divisions. These observations suggest that precocious expression of Rbp9 inhibits cystocyte proliferation. Therefore the precise onset of Rbp9 expression in germarium region 2a is critical for inhibiting their further proliferation and achieving their correct differentiation.

Purpose: The aim of this study was to explore the continuous usage intention of head-mounted display-based virtual reality (HMD-based VR) content among college students. The study also sought to understand how this intention is influenced by factors related to personal cognition, social aspects, VR content, and HMD-related elements.Methods: This descriptive correlational study used a self-report questionnaire to survey 217 students from two universities in Korea who had prior experience with HMD-based VR content.Results: The mean score for continuous usage intention of HMD-based VR content was 2.59±0.57 points (range, 1–5 points). Regarding the average frequency of HMD-based VR content usage, 64.5% of participants reported using it 1 to 2 times, while 91.7% indicated a total HMD-based VR usage period of less than 6 months. Factors such as personal cognition, VR content, social aspects, and HMD-related elements had explanatory power of 35.1%, 10.7%, 4.4%, and 2.5%, respectively, for the continuous usage intention of HMD-based VR content. Additionally, engagement (β=.45, p<.001), influential others (β=.37, p<.001), environmental support (β=–.18, p=.030), and cyber sickness (β=–.21, p=.001) were identified as having a significant influence.Conclusion: When developing HMD-based VR content, strategies to improve users’ personal cognition should be included. Additionally, it is necessary to develop strategies that enhance enjoyment and interest in the content, while also facilitating ongoing social support. Furthermore, coping strategies should be devised that take into account cyber sickness, a potential side effect of these devices.
Age-related epigenetic regulation in the brain and its role in neuronal diseases
( Jeongsil Kim-ha ),( Young-joon Kim ) 생화학분자생물학회(구 한국생화학분자생물학회) 2016 BMB Reports Vol.49 No.12
Accumulating evidence indicates many brain functions are mediated by epigenetic regulation of neural genes, and their dysregulations result in neuronal disorders. Experiences such as learning and recall, as well as physical exercise, induce neuronal activation through epigenetic modifications and by changing the noncoding RNA profiles. Animal models, brain samples from patients, and the development of diverse analytical methods have broadened our understanding of epigenetic regulation in the brain. Diverse and specific epigenetic changes are suggested to correlate with neuronal development, learning and memory, aging and age-related neuronal diseases. Although the results show some discrepancies, a careful comparison of the data (including methods, regions and conditions examined) would clarify the problems confronted in understanding epigenetic regulation in the brain.

This study discusses the distribution of the auxiliary do in the framework of the Minimalist Program. It is generally assumed that the auxiliary do appears in the context where Infl is not allowed to attach to a verbal element, that is, Infl is stranded. But how the context results doesn’t seem to have been clarified yet except a few typical cases such as negative and interrogative sentences. The auxiliary do also appears in emphatic, imperative and VP-ellipsis sentences. Particularly in case of the imperative, the context seems quite difficult to describe. All the Infl-stranding contexts should be explained in the same manner. This study does that as follows. The emphatic sentence needs do when Aff, which is the emphatic morpheme appearing in the same position as not, blocks the covert raising of the main verb. The VP-ellipsis sentence needs do when the ellipsis leaves I stranded. The imperative needs do when negative or emphatic, regardless of auxiliary be or have appearing. This is because the auxiliary has some meaning and thus is not allowed to raise. The inverted ordering Don’t you ~ in the imperative is due to its lack of the EPP effect.
