The purpose of this study was to test the structural model for the effect on abnormal eating behavior targeting 493 nurses. Results, The direct effects of variables affecting abnormal eating behavior were in the order of eating abstinence and socially imposed perfectionism, and these variables explained 85% of abnormal eating behavior. Explicit narcissism had a significant effect on abnormal eating behavior through socially imposed perfectionism and eating restraint, and sociocultural attitude toward appearance through eating restraint. In the multi-group moderating effect, the path coefficients between job stress and abnormal eating behavior, socially imposed perfectionism and abnormal eating behavior were different between groups. Therefore, it is necessary to find a way to lower the socially-imposed perfectionism and nursing intervention that can escape excessive eating abstinence.

Purpose: This study was done to test a hypothesized model, the Biobehavioral Family Model (BBFM), on the relationship of family emotional climate, security of parent-child relationship, depression symptoms and eating problems in adolescent girls, to further understanding of eating problems in this population. Methods: With a convenience sample of 647 girls, aged 15 to 18, a self-report survey was conducted which included the Korean form of the Eating Attitude Test (EAT-26) to assess eating problems. Results: The estimated results of the structural equation modeling indicated a good fit of data to the hypothesized model proposing that family emotional climate and security of parent-child relationship were associated with the risk of eating problems by way of depression symptoms. That is, negative family emotional climate and insecure parent-child relationship increased the risk of eating problems indirectly by way of depression symptoms. Conclusion: The findings are consistent with the BBFM, which suggests a psychobiologic influence of specific family processes on children's stress-sensitive physical disease activity by way of depression symptoms. Therefore, the applicability of the BBFM for understanding adolescent girls' eating problems is supported. The psychobiologic pathways from depression to eating pathology should be addressed in future studies.

The derived intervention levels in Korean foodstuffs were estimated using the dynamic ingestion pathway model which was developed considering Korean environment. The derived intervention levels were estimated from the intervention level of dose based on the thyroid committed dose equivalent of infant in the case of I-131, and the whole body committed dose equivalent for age groups and 13 kinds foodstuffs in the cases of Cs-137 and Sr-90. The derived intervention levels were shown as a considerable variation with deposition time and radionuclide. The adult was the most important age group in the estimation of derived intervention levels for Cs-137 and Sr-90. In the adult, the derived intervention levels for rice were 2390 and 47 Bq/kg for Cs-137 and Sr-90 in the case of deposition in summer, respectively, and 198 and 79 Bq/kg in the case of deposition in winter, respectively.

A methodology for calculating acceptable levels of contamination of radionuclides in soil for unrestricted use was described. Pathways of exposure include direct radiation from ground surfaces, ingestion of contaminated food and inhalation of resuspended radionuclides. Results calculated using site-specific data for Korean environment were discussed and compared with those estimated by other guidelines.

For the consideration of the influence on radioactive contamination of foods due to rain during the release period of radionuclides in a nuclear accident, the previous dynamic food chain model was improved. Wet interception coefficients for the agricultural plants were derived as a function of radionuclide and rainfall amount, and mathematical formula of the model was also re-established. In the results for the same time-integrated radioactive concentrations on the ground, radioactive contamination of foods decreased greatly by rainfall, and it decreased dramatically according to increasing rainfall amount. It means that predictive contamination in foods using the previous dynamic food chain model, in which dry interception to the agricultural plants is only considered, can be overestimated. Among radionuclides considering in this study ($^{137}Cs,\;^{90}Sr,\;^{131}I$), influence of rainfall for food contamination was the most sensitive to $^{131}I$, and the least sensitive to $^{90}Sr$.

동적섭식경로모델을 사용하여 "목초$\longrightarrow$우유$\longrightarrow$사람"의 핵종이동 경로에 대해 침적시점에 따른 입력변수의 민감도와 결과에 대한 불확실성분석을 수행하였다. Cs-137과 Sr-90의 경우 모든 침적시점에 대해 재부유인자가 가장 높은 중요도를 보였다. 두 핵종에 대해 침적시점에 따른 입력변수의 중요도의 변화는 비슷한 유형을 보였다. 목초의 성장기에서 전이율이 상대적으로 중요도가 높았고, Cs-137의 전이율은 Sr-90의 경우보다 높은 중요도를 나타냈다. 목초의 비성장기에서 Sr-90에 대한 농축인자의 중요도는 매우 높았다.

Purpose: The purpose of this study was to analyze factors influencing eating problems among young female adults. Methods: Participants were 193 young female adults aged 19 ~ 29 years who were recruited in August 2017. Four variables related to eating problems in young female adults, including body image dissatisfaction, self-esteem, trait anger, and depression, were measured using reliable instruments. Data were analyzed using the SPSS/WIN 21.0 program and Amos 24.0 for descriptive statistics, Pearson correlation coefficients, and path analysis. Results: The mean for eating problems in young female adults was 8.99, and 9.8% of subjects were classified as high risk with eating problems. Modified model demonstrated good model fit (${\chi}^2$/df 0.47, GFI 0.99, AGFI 0.99, NFI 0.99, SRMR 0.022, RMSEA 0.001). Path analysis showed that body image dissatisfaction had the greatest direct effect on eating problems. Depression did not have a direct effect on eating problems, whereas it had indirect effects on eating problems through body image dissatisfaction as the mediating factor. Self-esteem had direct effects on depression and indirect effects on eating problems through depression and body image dissatisfaction as mediating factors. Trait anger had direct effects on depression and body image dissatisfaction and indirect effects on eating problems through depression and body image dissatisfaction as mediating factors. These factors accounted for 46% of the total variance, and the fit indices of the model satisfied the criteria of fitness. Conclusion: The results of this study reveal the important role of body dissatisfaction and psychological factors such as self-esteem, trait anger, and depression on eating problems. These factors influencing eating problems should be considered when developing programs to improve eating problems in young female adults.

원자력시설의 사고시 대기중으로 누출된 방사성물질에 의해 오염된 토양으로부터 재배된 농작물로 인한 인체노출은 각종 환경오염물질에 의한 인체영향 연구결과에 보듯이 직접적인 방사능에 의한 인체노출 못지 않게 상당히 중요하다. 이러한 섭식경로를 통한 노출은 각 나라마다 서로 다른 토양조건 및 작물체종류의 다양성등 다른 양상을 보이고 있어, 연구가 수행된 미국이나 유럽등지의 평가방법을 그대로 사용하면 국내의 토양에서 재배되는 농작물이나 이를 이용한 축산물에 따른 한국인의 독특한 섭취양상을 충분히 고려하여 평가하기 어려울 수 있다.

Soil-to-plant transfer coefficients of Mn-54, Co-60, Zn-65, and Cs-137 were estimated for the edible parts of the rice, soybean, lettuce, carrot, and squash grown in different soils by radiotracer uptake experiments using pot cultures. The transfer coefficients of radionuclides were in the order of Zn-65 > Mn-54 > Cs-137 > Co-60 in most of the cases studied. The coefficients for soybean were roughly an order of magnitude higher than those for rice. Among vegetables, lettuce mostly showed the highest value and squash, the lowest. In the strongly acidic soils, transfer coefficients were much higher than in the moderately acidic soils. From the data obtained. crop-specific transfer coefficients of the four nuclides were proposed for the use in Korean food-chain radiation dose assessment.
