This study was done to evaluate the health and nutritional status of female college students in Seoul. The subjects were 63 healthy college students aged 20 to 29 years. Their body composition, dietary intakes, clinical blood indices were investigated. Their body composition was determined by means of a multifreqency bioelectrical impedance analysis. Their dietary intake was determined using 3-day record method and their nutrient intake was analyzed by Computer Aided Nutritional analysis program for professional (CAN-pro). Their hemoglobin, hematocrit, red blood cell (RBC), white blood cell (WBC) and mean corpuscular volume (MCV) were determined by semi-automated microcell counter (F-520). Their plasma total cholesterol, TG, and HDL-cholesterol levels were measured using test kits. All data were statistically analyzed by SAS PC package program. Their average consumption of calcium, iron vitamin A, vitamin B2 and niacin were 63.3%, 65.0%, 85.2%, 89.2% and 95.2% of RDA, respectively. The overall mean values of the hematological indices in the female college students were within the normal range. However anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (<36%) accounted for about 20% of the subjects. The mean levels of total cholesterol, HDL-cholesterol and TG were 188.4mg/dl, 69.9mg/dl and 67.4mg/dl, respectively. The percentages of the subjects with plasma total cholesterol level (> 200mg/dl) and LDL-cholesterol (＞130mg/dl) were about 41% and 30.4%, respectively. The data showed a significantly positive correlation between either body fat (%) or BMI and TG. However. there was a significantly negative correlation between either body fat (%) or BMI and HDL-cholesterol. These overall results suggest that it is necessary for college women to be educated regarding consuming more iron and vitamin C and less fat, in order to prevent iron deficiency anemia and/or cardiovascular diseases in later life.

The purpose of this study was to determine the basic materials needed for nutrition and health programs for aged people. In order to set up these programs, the nutritional habit, nutritional knowledge and functional health status (mobility, functional assessment, and falls efficacy) of the aged were measured, and their relationships were determined. Data was collected on 57 aged individuals that participated in the 'Exercise Program for the Aged' conducted by the National Health Insurance Corporation. These 57 subjects were interviewed and tested by direct measurement prior to conducting the program. The data was analyzed using the SPSS 13.0 Package. According to the results, the nutritional habit ranged from 24-50 out of 50, and the average was 37.2, which was above the middle level. The average nutritional knowledge was of 4.02 out of 5, which was considered reasonably high. Especially, more than half of these subjects were uneducated, but they had a high interest in nutrition. The average mobility was determined to be 9.2 seconds and the falls efficacy was 64.2 out of 100. In addition, subjects answered that they had a fear of falling due to low confidence, which indicates that safety education for the prevention of falls should be provided to aged individuals in the future. The results showed that notable counter-relations between nutritional habit and functional health status existed.

The purpose of this study was to investigate culinary arts and hospitality students' food safety practice behaviors, intentions, attitudes, and barriers to food safety compliance. This descriptive study used the self-report questionnaire. The convenience sample was composed of 266 college students majoring in culinary arts and hospitality. The students indicated that they never or rarely use a thermometer to determine if meats have been adequately cooked. Examples of positive food handling behaviors were hand washing, sanitation of fruits and vegetables, discarding of food past its expiration date, counter top sanitation, and proper food storage. Students strongly agreed it is their responsibility to practice food safety and to educate their employees about food safety. The primary barrier to proper food safety as ranked by student respondents is the misunderstanding about food labeling. Previous food safety education and internship experience appeared to improve the student respondents' perceived attitudes toward following the principles of food safety practices (p < 0.05), although behaviors and intentions to use the correct food safety practices were not affected. The findings of this study suggest that programs should consider integrating information and experiential learning opportunities in their courses that would be enhance student understanding about food safety. The outcomes of this study can be applied to develop food safety education materials and programs for culinary arts and hospitality students.

This study was conducted to investigate the quality assessment of performance of the university foodservice. Self administered questionnaires were collected from 305 students living in Incheon. Statistical data analysis was completed using a SPSS v. 10.0 program. The results were summarized as follows: 61.4% of male students and 48.1% of female students responded to have lunch regularly. Only 23.4% of male students and 14.1% of female students used the university foodservice daily. Reasons for the irregularity of lunch were responded as “lecture”, “eating when I want” and “appointment with friends”, etc. The quantity, temperature, nutritional value, appearance, hygiene, taste and freshness of foods and price of menus were evaluated as appropriate but using seasonal foods, number of side-dishes, etc. as unsatisfactory. Service speed, cloth hygiene, neatness and kindness of employee were evaluated as appropriate. For the facilities of foodservice, counter location, menu board and lighting facilities were evaluated as appropriate but heating facilities, disposition of tables and chairs of dining hall were as unsatisfactory. Sanitation of floors and walls of dining hall, restroom and utensils, etc. was evaluated as low.

In the modern society, magazine is a information communicating media which is an important element in assessing the whole of a nation's cultural standard. More subdivided fields of magazines are expanding according to the diversified concepts. As the variety of Korean edition of foreign magazines are increasing, the type of Women's magazines are also diversifying and expanding. By finding out the problems and analyzing the visual side of domestic women's magazines among the intense competition of the magazines, the design improvement program was requested. The analysis result from the visual side of domestic women's magazines tells us that the problem of current domestic women's magazines is that their identities are not clear. The cause can be divided into three reasons: First, it is the lack of creativity and originality. There is a limitation in arousing the readers' interests by designing the magazines with similar layouts. Second, there are no distinct design concepts in the magazines. It seems as if the uniformity is lacked as the impression the magazine gives is not clear. The diversification of layouts and the use of design elements could actually bring about a counter result. Third, the excessive advertisement pages is another reason. The ads that covers over 35% of the whole of the magazine can act as a factor that drops the readers' trust in the magazine.

The neutral section on electric railway system is significant sector in order to prevent short circuit of two electric powers. However, while electric trains pass the neutral section, those speed is decreased and the accident of AC electric traction system and the electric train would be occurred. So the countermeasures are urgently needed. The automatic power switching technology system that is current being research and development is system to improve these problems. Because main object of this system is power change using static switch in the neutral section, it's expected to cause a variety of transients. Especially, onboard transformer inrush current for electric railway train can be occurred more than rated current according to switching time. Therefore, the analysis and improvement are needed to ensure the stability of this system. In this paper, we analyze the operating characteristics of the automatic power switching technology system. Especially, it reviews inrush current according to the closing phase angle. And we propose control plan of inrush current considering the case that voltage is maintained due to counter electromotive force and regenerative braking operation of electric railway train. Finally, the proposed control scheme was reviewed using the transient analysis program.
