In the previous surveys conducted on the users of digital multimedia centers at major public libraries, their facilities, contents, staffs and operating system have been found to be the most significant factors for determining the user's satisfaction. The purpose of this study is to seek practical ways of improving digital information services at public libraries by surveying Hanbat Library Users' satisfaction on these four factors. The statistical analysis of the surveyed data has shown that the general satisfaction with the digital service was relatively good: 4.68 out of the maximum scale of 7, that their satisfaction with the facilities were increased but those with staffs and operating system were decreased, and that 69.7% of the users were not willing to learn how to use contents mainly because they do not trust the staffs' ability to teach. Therefore, it was confirmed that the continuous reeducation of staffs and the expansive recruiting of professionals are essential for improving digital information services.

In order to assess the general health effect due to air pollution and to determine the critical pollutant which is meant by the worst effect to health among various pollutants in Seoul, air quality measurements at 10 sites during $1983{\sim}1984$ were analyzed using Pollutant Standards Index(PSI) : This index has been ultimately proposed to describe the comprehensive degree of the air pollution by U.S. Environmental Protection Agency(EPA) since 1976. Total average of PSI in Seoul during the two years was 139 that is described in 'unhealthful' The highest PSI appeared in Winter 183 through the 2 years, the lowest in Summer 99, and Spring 129 and Fall 150 respectively, PSI in Deungchon dong and Seongsu dong which are industrial areas were very high in terms of 'very unhealthful', while shinlim dong was shown in low in terms of 'good'. TSP was a priority pollutant in Seoul as the most frequently occuring critical pollutant. Its frequency was 76.4% in Spring, 86.0% in Summer, 78.0% in Fall and 44.2% in Winter during the 2 years. In Winter, $TSP{\times}SO_2$ was an important term as the critical pollutant in Seoul. Oxidant was the most frequently occuring critical pollutant in Kwangwhamoon through the whole seasons. It was recommended that the PSI could be used to assess the air pollution administratively and legally in context with publich health.

The purpose of this study was to suggest an educational direction to aid in formulating a dietary life that is suited to Korea's multicultural families. This was achieved by analyzing the dietary life of immigrant women from multicultural families in Daegu. The study was carried out with 94 immigrant women form multicultural families who were served by public health center A (20 women), public health center B (47 women) and public health center C (27 women). Their home countries were China (55.3%), Vietnam (37.2%), Philippines (3.2%), Japan (2.1%), Uzbekistan (1.1%) and Thailand (1.1%). When the scores of their dietary balance were compared on the basis of the time they have been in Korea (Less than 1 year, 1~3 years, more than 3 years), we found that the score of immigrant women who stayed for less than 1 year was higher than those who stayed for more than 3 years (p<0.05) in terms of their intake of meats, fishes, potato, calcium, and carbohydrate. When subjects were asked about Korean food they wanted to learn how to cook, 30 different types of food were selected and 95.5% of the respondents wanted to learn in detail how to cook Korean food. The place most suitable for them to learn cooking was college (30.3%), while the house of their husband (2.2%) was lowest. Therefore, it seems that a college, public health center or welfare center are good places for immigrant women from multicultural families to participate in an education program that is designed to teach them how to cook Korean food.

The root of ginger (Zingiber officinale) contains gingerol, which is known to be responsible for its pharmacological activity. The essential oil extracted from ginger has been found to have various pharmacological effects. Thus, interest in the development of various beverages using ginger oil has recently increased. Therefore, in this study, the organoleptic quality assessment of cow milk, yogurt, kefir, soy milk, oat milk, and almond milk was conducted by supplementing them with oil extracted from ginger at various concentrations (supplemented with 0.5% increments from 0% up to 2%). A poor grade was obtained in the organoleptic quality evaluation, owing to the strong odor of ginger oil. However, when compared to that of the control, the samples supplemented with 0.5% ginger oil showed a good grade of organoleptic quality assessment. Therefore, this study is considered valuable as it is the first study to review the organoleptic quality assessment by supplementing milk, yogurt, kefir, soy milk, oat milk, and almond milk with ginger oil. Additionally, in order to improve organoleptic quality assessment, it is critical to estimate how much ginger oil supplementation concentration could be reduced and whether ginger oil exhibits various bio-activities at this concentration.

Objectives: Despite the importance of choosing and using a valid assessment tool for fear of cancer recurrence (FCR) for early detection and interventions, the validity of the FCR inventory has yet to be thoroughly investigated in Korea. This study explored the psychometric properties of the Fear of Cancer Recurrence Inventory-Severity (FCRI-S) subscale and assessed its applicability to cancer survivors in Korea. Methods: The survey involved 93 Korean individuals who had survived cancer. The reliability of the FCRI-S subscale was assessed using Cronbach's α and composite reliability (CR). Confirmatory factor analysis (CFA), along with tests for discriminant and convergent validity, was conducted to evaluate the construct validity of the FCRI-S subscale. Results: The FCRI-S subscale showed excellent internal consistency (Cronbach's α=0.88; CR=0.89). CFA showed a good factor structure for the FCRI-S subscale, and the correlations of the FCRI-S subscale with FCR-related measures (r=0.69 to 0.80) and other psychosocial measures (r=-0.23 to 0.37) confirmed both the convergent and discriminant validity of the FCRI-S subscale. Conclusions: This study confirmed the robust psychometric characteristics of the FCRI-S subscale among cancer survivors in Korea. The use of the FCRI-S subscale would be helpful for health professionals to rapidly screen FCR levels in clinical settings.

Purpose： The purpose of this study was to estimate obesity rate among mentally disabled children in six public schools in Korea. Furthermore, this study identified several factors that correlated with these children's obesity. The results of this study can help identify mentally disabled children who are at an increased risk for obesity and can be used to promote good health in this population. Methods： 1,102 subjectsfrom six public special schools were classified 4 groups who assessed for BMI for age-gender specific reference chart(1998) based on our previous data. Moreover, 207 parents were surveyed to identify predisposing factors for children's obesity, including characteristics of the children and parents, socioeconomic factors, children's eating habits, and children's exercise habits. Results： The prevalence of obesity among the 1,102 mentally disabled children was 17.3%. There was a statistically significant correlation between obesity and factors, such as age, maternal education, parents' perceptions about their child's obesity, frequency of breakfast, and exercise habits. Each of these factors was determined to have a statistically significant influence on obesity when all other factors were controlled in a multivariate analysis with multiple logistic regression analysis. Conclusions： Parental perceptions had an especially strong impact on the weight of their mentally disabled child. This is presumably due to the great influence that parents have on the lifestyles of their children, including dietary habits and frequency of exercise. Furthermore, the rate of obesity was directly proportional to the age of the child. The results of this study strongly indicate the need for preemptive health education programs that stress weight management for mentally disabled elementary school students.

Objectives : This study is to evaluate the awareness, attitude, practice and the countermeasures against passive smoking in Korean adults. Methods : By self-administered questionnaires, we assessed the knowledge, attitude, behavior for passive smoking and the countermeasure for reduction of it's harmful effects in 289 men and 238 women. Results : The subjects that have heard about passive smoking were 96.8% in total and well known were 26.4% of current smoker, 56.6% of ex-smoker, and 14.8% of non-smoker(p=0.001). The irritative symptom from passive smoking was the most frequent in non-smokers and the most common place where exposed to passive smoking was public place. For attitude against passive smoking in 'no smoking allowed area', ex-smokers were the most active to recommend to stop smoking. And for opinion about establishment of 'no smoking allowed area', the restriction by law was the best acceptable method in smokers, exsmokers, and nonsmokers. In marking of 'no smoking allowed area', 69.9% of smokers answered no smoking, but in non-marking area only 6.3% stop smoking. When smokers were recommended to stop smoking, the more subjects stop smoking with good feeling in marking area, but the less in non-marking area. The factor associated the high awareness of passive smoking were aged(OR=1.07, 1.03-1.12), men(OR=4.34, 2.32-8.46). The persons who have known well about passive smoking had good attitude and behavior to prevent of harmful effect of passive smoking. Conclusions : This study suggested that education program would be necessary to reduce the passive smoking.

To measure the effect of school zone on housing cost, Linear Regression Model is widely used, and school zone is known as a key determinant of housing cost in Korea. However, when the Hierarchical Linear Model (HLM) is applied with the same data, school effect on housing cost becomes statistically non-significant. It is because HLM effectively separates the effect of individual housing's attributes from the group effect. In sum, the housing cost of Kangnam, where good public schools are located, is apparently is higher than that of Kangbuk. However, the school effect on housing cost (Level 2) becomes non-significant when individual housing's attributes (Level 1) are controlled with HLM.
