Present study investigates on the impact of resources and characteristics of the tenure choice for divorced women in Korea. The authors utilize the micro data from the Korea Census (2% sample) provided by the National Statistical Office. The authors apply the bivariate probit model to eliminate selection bias that could incur due to sample selectivity, from a chain of marital disruption and tenure choices. This study starts with a descriptive explanation of homeownership after divorce from 1985 to 2005. It concluded that divorce results in a substantial attrition of homeownership. The authors found that out for many women, divorce initiates a process of downward mobility on the housing ladder. The probability to own housing is much lower for divorced women than for women who are not divorced. The present study concludes by suggesting some policy implications for divorced women who have limited access to housing stability. The authors also suggest some future studies that can compensate the empirical limitations of the present study.

황성연,김영만,조대희 한국식품영양학회 1998 韓國食品營養學會誌 Vol.11 No.4

바켓반죽의 저온숙성이 바켓의 품질에 미치는 영향을 조사하였다. 글루텐을 완전하게 발전시킨 반죽을 세등분하여 즉시 성형하여 구운 것과 1∼-1℃에서 각각 24, 48시간 저온숙성시키고 발효 및 저온숙성 중의 pH변화와 유기산 종류 및 그 함량을 분석하였다. 바켓 발효과정중 생성되는 유기산은 acetic acid가 가장 많았으며 다음은 lactic acid였으며 저온숙성 중 pH변화는 극히 적었다. 각각의 시료를 20℃에서 저장보관하면서 DSC를 사용하여 crumb의 enthalpy 변화로 바켓의 노화 정도를 측정한 결과 반죽의 저온숙성 기간의 차이는 제품의 노화에 영향을 거의 미치지 않았으며 종류별로 구워낸 바켓의 저장중에 enthalpy가 증가하여 노화도에 차이를 보였다. 한편 관능검사의 결과는 2시간 발효시킨 바켓의 외관이 가장 좋았다. 그러나 맛, 조직감, 향미 등은 24시간 저온숙성시킨 것이 다른 것에 비하여 높은 평점을 받았다. This study was conducted to investigate influences of cold aged dough on the quality of bagutte. After 2 hours fermenting, the dough was divided 2 parts and they were stored in the refrigirator adjusted 1∼-1℃. The cold aging time was 24, 48 hours respectively. After 2 hours fermentation, the dough's pH was 5.45 and 24, 48 hours cold aged dough were 4.99, 4.81. During cold aging, the difference of pH was not significant. The main organic acids in the baguette were lactic acid, acetic acid and malic acid. Among these organic acids, the acetic acid was the largest quantity regardlessly in different fermentation and the cold aging time. Right after baking, the enthalphy of all samples were almost same even though in different cold aging time, but during different storage periods they showed the difference of retrogradation by the increase of the enthalphy. 24 hours cold aging baguette had the best taste, aroma and texture in the bread's score sheet.

In order to find out and show the maximum amount of water and fat which can be mixed and emulsified with the given meat ingredients, the chemical components and specific properties of the followings are investigated. The chemical content of pork and lard were water 74.3%, 15.2%, protein 21.3%, 6.7% , fat 4.7%, 81.3% and w/p of pork was 3.48, F/P was 0.22. Among the protein, the content of salt soluble proteins of pork was 43.2. The moisture was decreased by the increasing fat level and the fat contents were increased by the increasing of fat level so, by adding fat of 50% level, the fat content of the finished sausages will be less than 30%. But the minimum protein level was 10.5% which is above the 10% that is considered as the minimum level for the acceptable meat emulsion. The lower stability was found in the 20~40% of fat levels in the formulations that consists of higher levels of fat and added water.

Objectives : This study was designed to explore body-shape satisfaction and adjustment functions in 410 adolescent school girls. Methods : After underweight, normal-weight and overweight groups were identified among 410 high school girls according to BMI(body mass index), we compared current weight & height, ideal weight & height, subtracted value of ideal weight from current weight, subtracted value of ideal height from current height, subtracted value of ideal BMI from current BMI, weight dissatisfaction, height dissatisfaction, body-shape dissatisfaction, and EAT-26(Eating Attitude Test-26), OSIQ(Offer Self-Image Questionnaire for Adolescents), STAI (State-Trait Anxiety Inventory), BDI(Beck Depression Inventory), BITE(Bulimic Investigatory Test Edinburgh) among the three groups. Results : 1) The subjects consisted with overweight group(BMI〉25, N=27, 6.6%), normal-weight group(19≤BMI≤25, N=278, 67.8%), and underweight group(BMI〈19, N=105, 25.6%). 2) In comparison to other groups, overweight group was significantly different in subtracted value of ideal weight from current weight and subtracted value of ideal height from current height. These results suggest that overweight group wants greater body-shape change than other groups. Overweight group was significantly shorter in height than underweight group. There were no significant differences in ideal height among the groups. 3) Overweight group and normal-weight group showed significantly higher weight dissatisfaction than underweight group. There were no significant differences in height dissatisfaction and body-shape dissatisfaction among the three groups. All groups showed higher weight, height dissatisfaction and body-shape dissatisfaction except higher weight dissatisfaction in underweight group. 4) In comparison of overweignt group with other groups by mean difference of each scale, there was significant difference in superior adjustment subscale of the OSIQ and symptom subscale of the BITE between overweight group and other groups. There was also significant difference in symptom serenity subscale of the BITE between overweight and underweight groups. There was no significant difference in EAT-26, STAI, BDI, other subscales of OSIQ among the groups. Conclusions : 1) The distribution rate of overweight group was lower than in western studies. 2) These results suggest that overweight group wants greater body-shape change than other groups, and overweight group may have binge-eating and poor coping system.

Cefodizime, a third cephalosporine, was originally developed for use in infectious disease as an advanced antibiotics. Cefodizime has also been known to play a meaningful role in activating natural killer properties of immune cells as well as enhancing immunological parameters such as phagocytosis. Furthermore, as the infection can result in remarkable changes for homeostatic mediators, it is expected that cefodizime may initiate the strong immuno- modualtory effect. In the present work, we investigated whether cefodizime has a biphasic effect of anti-bacteria and immunomodulation via macrophage. For the study, we isolated mouse peritoneal macrophages and treated with cefodizime 10㎍/㎖, 50㎍/㎖, 100㎍/㎖, IFN-v 10U/㎖.+LPS l㎍/㎖ Cells were then incubated for 4, 8, 12, and 24hrs to analysis the expression of IL-1, IL-6, IL-12 mRNA from macrophages. The results showed that cytokines were expressed more than that of control in a time-dependent manner and 100㎍/㎖ cefodizime group showed the greatest expression as much as the positive control (IFN-v+LPS)showed at 24h. In conclusion, cefodizime can play a significant role for the expression of pro-inflammatory cytokines, IL-1, IL-6, and IL-12 in earlier stage so that macrophages and other immune cells can response to the infectious substances, immediately. Moreover, when such pro-inflammatory cytokines are increased, we can also expect that the enhancement of cell-cell interaction of NK cell, CTL and B cell by cefodizime can affect the immunomodulatory effect along with its major role in anti-bacterial effect.
