전경열 (사)한국조리학회 2020 한국조리학회지 Vol.26 No.5
This study attempts to investigate the relations among the financial ratios of US restaurants in five categories (profitability, activity, solvency, liquidity, and working capital management) through three different economic periods (pre-recession, recession, and post-recession). The relationship between restaurant operations focusing on working capital management and economic conditions is also investigated. For the research objectives, the study adopted the financial data of publicly traded restaurant companies in the United States. The result of this study shows that the U.S. restaurant companies have increased their reliance on venders' credits for their working capital management through difficult economic periods. However, the change in the cash holding level is not confirmative. The finding of this study provides the practitioners and academia with guidance in interpreting the financial information about the restaurant industry under different economic situations.

全京烈 건국대학교 교육대학원 1983 敎育論叢 Vol.3 No.-
Ⅰ. Problems and Method The purpose of this investigation was an attempt to identify the psychoneurotic tendencies of the college students and to compare these results with self-concept scores. The versions of Madusely Medical Questionaire(M.M.Q.) and self-concept test were administered to 174 college students at Kon-Kuk University. The results were analyzed in terms of the characteristics of student's peculiar background. Ⅱ. Hypotheses Hypothesis Ⅰ: There are significant differences between non-employed students and employed students in neurotic tendencies. Hypothesis Ⅱ: There are significant differences between non-employed students and employed students in self-concept scores. Hypothesis Ⅲ: There are significant differences between normal students and neurotic students in self-concept scores. Ⅲ. Results After the investigation, the findings were revealed as follows: 1. The 30% of students showed fairly high level of neurotic tendencies. 2. A significant difference was noted between male and female students by being female higher neurotic tendencies than male. 3. In the analysis of students' personal characteristics, the findings revealed that the students who came from rural areas, were Buddists, non-smokers, non-drinkers and living in rented rooms showed higher neurotic tendencies. All the following Hypotheses were confirmed as follows; Hypothesis Ⅰ: There are significant differences between non-employed students and employed students in neurotic tendencies. The Hypothesis Ⅰ was confirmed at the high level of significance.(p<.05) Hypothesis Ⅱ: There are significant differences between non-employed students and employed students in self-concept scores. The Hypothesis Ⅱ was confirmed partially. Hypothesis Ⅲ: There are significant differences between normal students and neurotic students in self-concept scores. The Hypothesis Ⅲ was confirmed at the high level of significance. (p<.005). Ⅳ. Conclusions and Suggestions. On the basis of the above findings, the following conclusions and suggestions for further studies could be drawn. 1. Non-employed students showes higher scores in neurotic tendencies than employed students. 2. Non-employed students showes lower in self-concept than employed students partially. 3. Normal students show lower scores in self-concept than employed students.

This study examined the impact of culinary and nutrition education on cooking attitude, cooking skills and dietary pattern for college students. A one-group, pre- and post-test design was employed to measure the changes in cooking behavior and eating behavior. A total of thirty-four college students, ages 18 to 24, participated in the study. For analysis, change scores in cooking attitude and cooking skills were calculated from the difference between pre- and post-scores for each student. In order to assess the impact of the culinary and nutrition class on consumption in fruits and vegetables between pre-, and post-test, a paired t-test was used. The results showed that there were significant improvements in favorable attitude toward cooking and cooking skills between pre -and post-tests. The study revealed that participants significantly increased consumption of fruits and vegetables after the course. The study suggests that the culinary and nutrition class is effective to enhance college students’ cooking attitude and skills and to promote consumption of fruits and vegetables. The results of the current study could offer an empirical evidence for implementation of public policies in the contexts of a university campus. Furthermore, this paper discusses the theoretical and practical implications of the findings and future research ideas.

As fracture of the patella may cause loss of continuity of the extensor mechanism and incongruity of the pateilofemoral joint, the aim of treatment is to restore function and strength of the knee and to minimize posttraumatic asteoarthritis by closed or open methods. To know which method is adequate to fixation of the patellar fractures, the authors reviewed 35 cases of the patellar fractures, which were treated with K wire fixation, circumferential wiring, madified tension band wiring or combined circumferential wiring with modified tension band wiring, with radiological change of patellar length after exercise, and obtained the following results: 1. Postoperative lengthening of the patella occurred in 17 out of 35 cases(4No) and the range was 1.3 to 8.0mm, mean 3.1mm 2. Pateilar lengthening occurred in cases with K-wire fixation or circumferential wiring more than modified tension band or combined circumferentiai wiring with modified tension band fixation 3 Modified tension band added to circumferential wiring may be obtained more rigid fixation in comminuted fracture, especially.

Purpose: The birth rate in Korea continue to decline to 0.92 births per woman, with steeper decline tendency in Seoul by 0.78 births. Therefore, the Seoul city is conducting community-based preconception care to promote the positive result of pregnancy, but to screen for infertility diagnosis. The purpose of this study is to evaluate the risk factors related to the fertility rate of married women. Methods: This cross-sectional study was conducted in community of 12 regional areas of the Seoul, the capital of South Korea. The study population consisted of voluntary participants, between 1st of May 2019 to 30th of November 2019. Data was collected via questionnaire, containing various elements associated with risk factors of pregnancy outcome. Results: Of the 2,274 voluntarily participated married woman in this progect, 443 out of 2,274(19.5%) candidates were identified as infertile. Duration of primary and secondary infertility was 1.7±1.1years and 2.2±1.5years respectively. The mean age of fertile and infertile women were 31.9±3.3years and 33.2±3.8years old respectively, resulted in statistically significant values(p<0.001). The univariate analysis and multivariate logistic regression were done for identification of the risk factors of the infertility. Conclusion: This study contributed in identifying various significant risk factors affecting female infertility. Multiple policies could be established to prevent infertility and improve the fertility rate based on the result of this study. Further studies are required to identify male risk factors and any other infertility associated clinical risk factors.
