여경옥,배세정 (사)한국조리학회 2019 한국조리학회지 Vol.25 No.12
The purpose of this study was to understand the consumers' perception of rice noodles in the foodservice market and to present the basic data necessary for the restaurant's marketing strategy through the importance-satisfaction analysis on the selection attributes of rice noodles. In this study, a survey was conducted on self-filled surveys from March 5, 2018 to April 20, 2018, targeting consumers who have purchased a restaurant rice noodle menu in Seoul and Gyeonggi. According to the research result, the importance of rice noodles selection attribute was very high in taste, freshness, and sanitation items, but the menu diversity and calorie items were relatively low. The satisfaction of rice noodle selection attribute was very high in nutrition, taste and calorie items, but the variety of menu and price items were relatively low. This study analyzed the importance-satisfaction on the selection attributes of rice noodles using IPA technique, and found the consumer's perception of rice noodles in the restaurant market and suggested the basic data necessary for restaurant marketing strategy.

This study empirically analyzed the effects of employees` sense of humor on job satisfaction and turnover intention focusing on those who work for restaurants in Seoul to provide preliminary data for effective human resource management in the foodservice industry. In terms of a sense of humor, meta message sensitivity, preference for humor, emotional expression, and coping scale of a sense of humor were drawn as the factors. The findings are as follows. First, among the factors of humor, preference for humor, reaction to humor, and meta message sensibility affected job satisfaction positively in order. On the contrary, emotional expression was found not to affect it. Second, preference for humor and emotional expression affected turnover intention negatively in order whereas meta message sensibility and reaction to humor did not affect it. Therefore, based on the research result that a sense of humor affects job satisfaction and turnover intention, it is needed to recognize the importance of humor and consider evaluation on a sense of humor when screening employees.

N/A Objective : We investigated the effects on the cell cycle and p53 expression by the treatment of various concentrations of staurosporine to elucidate the molecular mechanism of staurosporine induced cell cycle arrest in MCF-7 cell line. Methods : Various concentrations of staurosporine were treated in MCF-7 cells cultured with RPMI 1640 media. The harvested cells were fixed and permeabilized with 1% paraformaldehyde and absolute methanol. Then the cells were stained indirectly with anti-p53 primary antibody and FITC conjugated goat anti-mouse(GAM)-IgG secondary antibody. Sequentially DNA were stained with 0.1% RNase and PI solution. These stained cells were analyzed by the standard FACScan flow cytometer. The obtained results were analyzed further with WinList 3.0, and ModiFit LT software program. Results : MCF-7 cells were arrested mostly in G1 phase of cell cycle at 5-10 nM of staurosporine, however, the cells were arrested in G2 phase at 20-100 nM of staurosporine. The expressions of p53 protein were higher in the MCF-7 cells treated with both concentrations of 10 nM and 100 nM of staurosporine compaired with the control cells. This suggests that the p53 may be involved in the mechanism of G1 and G2M arrest of cell cycle in MCF-7 cell. Conclusion : The points of arrest in cell cycle differred depending on the concentrations of staurosporine and these cell cycle arrests at G0G1 and G2M pahse were related with p53 protein expression. It suggested that these results could be extended to study for staurosporine to be usefull as a potential anti-tumor agent.

연구목적 : 갱년기 여성에서 호르몬 대체요법 실시시 Vit. D3의 추가 투여가 골밀도에 미치는 영향을 알아보고자 하였다. 연구 대상 : 1992년부터 1998년 사이에 갱년기 클리닉을 방문한 388명을 대상으로 하여 투여 방법에 따라 5군으로 나누었다. A 군 : 에스트로젠 단독요법군 (n=148), B 군 : 에스트로젠-프로제스테론 병합요법군 (n=103), C군 : 에스트로젠 + Vit. D3 투여군 (n=36), D 군 : 에스트로젠, 프로제스테론 + Vit.D3 투여군, E 군 : 비 투여군 (n=60). 연구 방법 : 호르몬 대체 요법 시작 전과 시작 후 2년 간격으로 이중에너지 방사선 흡수 계측법(DEXA, Hologic)을 사용하여 요추의 골밀도와 대퇴골 경부의 골밀도를 측정하였다. 통계 : 연구 대상군들의 골밀도 변화 비교는 paired t-test, one way ANOVA test와 student's t-test를 실시하였다. 결과 : 각 치료군간의 환자특성 및 기저 골밀도 치에 따른 환자특성은 차이가 없었으며, 프로제스테론 병합투여 여부는 골밀도에 의의있는 영향을 끼치지 않았다. Vit.D3 추가 투여시 기저 골밀도가 정상인 군은 대퇴 골두와 요추에서 단독 호르몬 치료군에 비해 모두 의의 있는 증가소견을 보이지 않았으나 기저 골밀도가 골결핍을 보인 군은 에스트로젠과 Vit.D3 투여군의 경우 요추에서 6.1±3.6% (p > 0.05), 대퇴 골두에서 8.5±3.1%(p < 0.05), 프로제스테론 병합요법과 Vit.D3 투여군의 경우 요추에서 5.9±4.1% (p > 0.05), 대퇴골두에서 6.7±4.1%(p < 0.05), 골다공증을 보인 군은 위순서대로 각각 6.7±3.4% (p > 0.05), 11.0±2.1%(p < 0.05), 6.1±1.1% (p > 0.05), 9.1±0.8%(p < 0.05)을 보였다. 결론 : 갱년기 호르몬 치료시 Vit.D3 추가투여는 기저 골밀도가 정상인 군에서는 골밀도 증가에 의의가 없으며, 골결핍증과 골다공증이 있는 여성은 Vit.D3 추가 병합투여가 골밀도 증가 도움을 준다고 할 수 있지만 요추보다는 대퇴골두 골밀도 증가에 더욱 효과가 있다고 할수 있다. Objective : To determine the effect of the addition of Vit. D3 (1,25-Dihydroxychole calciferol D3) to the conventional postmenopausal hormone replacement therapy on bone mineral density(BMD) Design : A 2-year retrospective , randomized study Setting : Department of Obstetrics and Gynecology of Catholic university hospital Patients : 388 postmenopausal women were recruited and divided into 5 groups according to treatment regimen; A: conjugated estrogens only treated group(n=146), B : conjugated estrogens and progesterone treated group(n=103), C : conjugated estrogens and Vit.D3 treated group (n=36), D : conjugated estrogens, progesterone and Vit.D3 treated group (n=41), E : control group (n=60). Methods : The bone mineral density of the lumbar spines and femoral neck were determined by dual-energy X-ray absorptiometry(DEXA) every 2 years.Statistics : The difference between before and after treatment was determined by paired t-test. The comparison among the groups were determined by one way ANOVA test and student's t-test Results : The addition of progesterone to estrogen showed insignificant increase in the lumbar and femoral neck BMD. The addition of Vit. D3 compared with conventional hormone replacement therapy insignificantly influened bone density in women with initially normal BMD, but definitely increase in women with initially osteopenic and osteoporotic BMD of femoral neck rather than lumar spine(p<0.05). Conclusion : The use of Vit. D3 combined with postmenopausal estrogen replacement effects the increase of BMD in low bone density than normal bone density, especially femoral neck.
