This study investigated the eating habits of elementary school children and their perceptions related to traditional Korean foods, based on the health belief model. The subjects were fifth grade elementary school children (274 boys and 274 girls) in eight Korean cities. The results were as follows: The children ate almost three meals per day and were grateful for their meals. However, they irregularly consumed meals and snacks. They tended to eat heartily and did not eat foods that they had not yet eaten. Their meals were based on rice and they have eaten kimchi and vegetables at almost every meal. However, they had undesirable habits in eating other foods, such as fruits, fish, soybeans, and sweet foods. They did not sensitively or seriously perceive their eating habits in relation to their health. They perceived that it was very good for their nutrition, health, and tastes to eat traditional Korean foods, and they had pride in traditional Korean foods and eating style. Although they expressed some difficulty regarding availability and preparation of traditional Korean foods, they hardly felt difficulty in eating them. They had high dietary self-efficacy with regard to eating these foods, except for two items of self-regulation. Their eating habits showed positive correlation with dietary self-efficacy, perceived susceptibility, and perceived benefit. In conclusion, eating habits of elementary school children in relation to traditional Korean foods are not desirable, but not serious. They did not sensitively or seriously perceive their eating habits in relation to their health. However, they perceived that it was very good for their nutrition and health to eat traditional Korean foods, did not have a high level of difficulty in eating them, and had high dietary self-efficacy with regard to eating them. Therefore, we suggest that children should be exposed to various traditional Korean foods, along with education about them, in order to enhance their concern and motivation to eat them.

The purpose of this research is to investigate the mediating effect of sense of self-control in the relationship between loneliness and preparation for death of seniors living alone. The research results can be summarized as follows: First, the difference between the feeling of loneliness and the feeling of self-control, depending on the personal trait of the subject was examined. The subjects that are male, have no faith, and have their own houses showed a more intense feeling of loneliness than subjects that are female, have faith, and have their own houses, respectively. Also, the subjects that have their own houses and are engaged in economic activities showed a more intense feeling of self-control. Second, when it comes to the relationship between loneliness and preparation for death, seniors who had been hospitalized and had lower loneliness showed higher levels of preparation for death. Third, the analysis on the effect on sense of self-control revealed that the younger and the lower the loneliness, the higher the sense of self-control. Fourth, such sense of self-control had a partial mediating effect in the relationship between loneliness and preparation for death. Therefore, this research suggested measures to promote activities to prepare for death by decreasing loneliness and strengthening sense of self-control of the elderly living alone.

This study intends to verify the poverty characteristics of the rural elderly households so as to provide more specific data for the intervention of social welfare in the improvement of quality of life of the rural elderly. According to my study of the absolute poverty ratio, the poverty gap, the relative poverty ratio, the subjective poverty ratio, the subjective economic level and the life satisfaction level of the rural elderly households in comparison with those of the other groups, the conclusion is as follows: First, the total living cost of the rural elderly households is rather low with the food cost taking about 30% of the total living cost. Second, in terms of the poverty ratio based on socio-demographic characteristics, higher poverty ratio show among women, older people and households of fewer members. Third, 82.2% of the rural elderly households living with an income below the minimum living cost is found around the poverty line. Fourth, the rural elderly households show a comparatively higher poverty ratio than the other groups in the absolute and relative poverty, but lower economic strain than other groups in the subjective poverty ratio and life satisfaction level. In short, the rural elderly households' poverty level is generally high and therefore need ways of active economic supports, while a political approach to the subjective needs of the regional and intergenerational groups is also required.

This research aimed at identifying the influential factors on high school students' dress code compliance. Specifically, the relationship between the perceived strength and importance of dress codes and dress code compliance, and the relationship between dress code compliance and creativity, self esteem, and school adaptation were examined. For this purpose, reliability tests, multiple regressions, and t-tests were conducted using the data collected from 866 male and female students from six Co-Ed high schools located in Seoul. The results are as follows. First, the more students perceived the school dress codes to be stronger and more important, they were more likely to comply to the dress codes. Second, compared to the low-compliance group, the high-compliance group had higher self-esteem and creativity. Third, compared to the low-compliance group, the high-compliance group showed better adaptation to their teachers, classes, and school rules. However, the two groups were not significantly different in terms of their adaptation to peer groups.

The purpose of the study was to present basic data to evaluation of the spatial resolution for exposure class(EC) in computed radiography(CR) by using the modulation transfer function(MTF). In this study, MTF was measured the edge method by using image plate(IP) of $100{\mu}mm$ pixels. A standard beam quality RQA5 based on an international electro-technical commission(IEC) standard was used to perform the X-ray imaging studies. Digital imaging began to set the sensitivity to EC 50, 100, 200, 300, 400, 600, 800, 1200 in X-ray irradiated to IP. The MTF 50% and 10% in the final images was analysis by using an authorized image analysis program the Origin 8.0 and the image J. As a results, the EC 200 was the best spatial resolution at MTF 50% ($1.979{\pm}0.114lp/mm$) and MTF 10% ($3.932{\pm}0.041$). Therefore, the EC 200 could be useful for the diagnosis of diseases that require high spatial resolution such as fractures.

Thick film $TiO_{2}/WO_{3}$ butane gas sensors were fabricated by the screen printing method and their gas sensing characteristics were investigated. The sensitivity of $TiO_{2}/WO_{3}$ thick film was higher than that of pure $WO_{3}$ film to butane. The $WO_{3}$ film with 2wt.% $TiO_{2}$ showed the highest sensitivity to butane. And the optimum heat treatment temperature was $650^{\circ}C$. That film showed the highest sensitivity to butane at the operating temperature of $350^{\circ}C$. The sensitivity of the film to 20000ppm butane in air was 80% at the operating temperature of $350^{\circ}C$.
