本 硏究는 都市 主婦 124 名을 대상으로 設問 紙法을 이용하여 食生活에서 나타나는 男·의 差異를 調査하였으며, 그 結果는 다음과 같았다. 1) 成長期에 男子형제에 비해 불균형된 食品 分配를 받았던 主婦가 全體의 약 38%로 나타났으며 특히, 육류와 특별한 행사음식의 分配에서 차이가 있었던 것으로 나타났다. 2) 이러한 불균형된 식품분배의 원인은 식품 供給의 부족보다는 男兒先好思想이 더 중요한 원인으로 나타났다. 3) 현재 食事形態, 內容에서 男女의 구분은 사라지고 있었으나, 아직도 47.7%의 主婦가 아들의 食事內容에 더욱 신경을 쓰는 것으로 나타나서 표면적으로 나타나는 意識의 변화에 반해 여전히 sex bias가 존재함을 보여주었다. 4) 經濟的 요인인 가정의 월수입과 社會的 요인인 主婦의 敎育水準은 식생활에서 나타나는 男·女差異와 유의적인 상관관계가 있었다. 즉, 주부의 敎育水準이 높을수록, 가정의 월수입이 높을수록 食生活에서 나타나는 男女差異를 반대하는 경향이었다.

According as the economic growth and the development of highly industrialized society have improved the nation`s standard of living, a great change in recognition of public health has occurred and also brought about a concomitant change in the roles and responsibilities of nutritionists. Consequently, the curriculum of Junior Colleges is required to be revised so as to provide substantial education through which the acquisition of necessary professional knowledge and technique as intermediate technicians and the efficient training can be achieved. On the basis of the survey and analysis of the current curriculum and of the functional structures of nutritionists, this study made an attempt to frame a model curriculum that may provide effective education and training and help to establish a desirable curriculum of Junior Colleges.

The aim of this study was to enhance the proliferation efficiency of spermatogonial stem cells (SSCs). In order to improve the proliferation efficiency, we investigated new factors that promote the proliferation of SSCs using in vitro culture method with natural plant extracts. Germ cell populations containing SSCs were collected 6- to 8-days-old from C57BL/6-TG-EGFP (C57GFP) mice and SSCs were isolated from the collected cells via magnetic-activated cell sorting (MACS). Since then, SSCs were cultured for a week with culture medium containing natural plant extracts at concentration of 0.1, 1, and 10 μg/mL. After a week of culture, we looked for an increase, especially a dose-dependent increase, in the number of cells compared to that of the control group. A dose-dependent increase, in the number of cells was observed in the Petasides japonicus-treated groups. Furthermore, we carried out repeated experiment that is process consisting of selection and additional segmentation to explore new factors for activating SSCs at the molecular level. As a results, Petasides japonicus butanol fraction significantly increased the proliferation rate of SSCs in a dose-dependent manner among Petasides japonicus fraction samples. We identified normal expression level of PLZF in SSCs cultured with plant extracts using immunocytochemistry method. Furthermore, we also carried out qRT-PCR and identified normal expression level of Lhx1 and GFRα1. The finding of this study could contribute to improvement of proliferation and activation for SSCs, using culture method with natural plant extracts.
