The purpose of this study is to suggest basic data and the direction for revising the curricula of the departments of Home Economics Education toward developmental and efficient ones. The current 23 curricula of all the department of Home Economics Education in Korea were analyzed and compared with the course of the subject “Practical Arts”included in the 5th Study Course of Secondary School to get the following results. 1) Only three subjects are commonly established in all the colleges, and they are Nutrition(obligatory in 23 colleges), Home Economics (obligatory in 21, optional in 2) and Housing (obligatory in 21, optional in 2). 2) Some subjects have various names differing with colleges, though the contents being the same, 8 subjects are established under more than 7 titles. 3) Principles of Home Economics and Home Education, which are obligatory subjects for the majors in Home Economics Education, are established with far less number of scores than the instructions given from the specialists. 4) Subjects over-subdivided beyond necessity are sometimes established, and some curricula are showing the lack of balance in distributing scores among disciplines after concentrating on a particular discipline. 5) Too few subjects are established entirely for experiment and exercise. 6) There is almost no subject related with the technics for domestic life, vocation and career which are included in the Secondary School Course.

Convertible bonds are financial products that contain the nature of both bonds and shares, which are generally issued by companies with lower credit ratings to increase liquidity. Conversion bonds rely on qualitative judgment in the past, although decision-making on whether and when to exercise the right to convert is the most important issue. Therefore, this paper proposes to apply artificial neural network techniques to scientifically determine the exercise of conversion rights. We distinguish between a total of 1,800 learning data published in the past and 200 predictive experimental data and build an artificial neural network learning model. As a result, the parity performance in most groups was excellent, achieving an average excess of about 10% or more. In particular, groups 3-6 recorded an average excess of about 20% and group 6 recorded an average excess of about 37%. This paper is meaningful in that it focused on solving decision problems by converging and applying machine learning techniques, a representative technology of the fourth industry, to the financial sector.

The purpose of this study was to discover the effects on women's health education for college women on their health promotion behaviors and the health related knowledge. The content of women's health education consisted of sex education, smoking, alcohol, exercise, nutrition, diet and stress management. “A Women and Heath” course was provided as an optional full term subject in the years of 2002 and 2003 at C University in G City. Out of 210 students who had chosen this course, 134 had agreed to participate in the research and had answered the same questionnaire which was given before the education and 14 weeks after the course at the last class. The findings are as follows： 1. It was found that the subjects have obtained knowledge mainly from television, radio, the Internet, women's magazines in order before the education. 2. Knowledge related to women"s health origionally scored low(average 1.92 out of 5). However, having completed a course on women and their health, they showed a significant increase of knowledge statistically(t＝26.945, p＝ .001) with average score of 3.48. 3. Health promotion behaviors who had completed the course has statistically significantly increased (t＝6.464, p＝ .001) compared to before the education. The results of this study are that by providing a women's health related course for college women on a regular basis, they could broaden their health related knowledge and become more active in practicing health promotion behaviors. This shows us the need to broaden the curriculum on women's health at the college level so that women have good knowledge and practice the knowledge for the sake of their health throughout their life.

Background: Korean people could abuse healthy foods as well as medications, which might cause serious side effects. The aim of this study was elucidating liver dysfunction due to the self-medications of hepatotonics, healthy foods and herb medications by nested case-control study. Methods: Study subjects were drawn from male members of Seoul Cohort Study who were recruited by self-administered structured questionnaire survey through mailing to the healthy men between the age of 40 and 59 years through the program of biennial health check-up offered by Korea Medical Insurance Corporation(KMIC). The liver dysfunction was defined as the level of serum AST and ALT above 40 IU/L and increased in more than one hunderd per-cent during the 2 year follow-up period. To estimate the odds ratio between self-medication and liver dysfunction after controlling for potential confounders, logistic regression was performed. Results: During the follow-up period, 30 members were identified to fit into case criteria and 2,625 members were selected as control. In logistic regression analyses, history of healthy foods intake, age under 45 years, obesity, and habit of regular exercise were significantly associated with liver dysfunction. The following factors exhibited no statistical significance: intake of hepatotonics, of herb medicine; history of disease in family, of operation, and of radiologic examination; smoking habits and drinking amounts. Conclusion: The significant association between the intake of healthy foods and the liver dysfunction illustrates that chronically optional overuse of healthy foods might bring to hazards to health. As the increasing trend of the size of purchasing healthy foods in Korea, pharmacoepidemiologic studies evaluating the safety and efficacy of the widely used healthy foods should be performed in the near future.
