The purpose of this study was to analyse the properties of leisure activity and the life satisfaction in the case of Korea Science Academy(KSA) students and Min Jok Leadership Academy(MLA) students. The participants consisted of KSA students(male:122, female:44) and MLA students(male:71, female:113) with voluntary consent. We had achieved the following results. 1) For leisure activity, KSA and MLA's male students showed the highest ratio for participation in the sports, KSA's female students in the taste-culture activity and MLA's female students in the sight-seeing. 2) The response showed that stress treatment was the principal reason of leisure activity's need. 3) Over 50% of the male students were satisfied with the present leisure activity but 12% of the KSA male students and 14% of the MLA female 14% answered to the "unsatisfactory" or "very unsatisfactory". 4) Mental stress treatment showed the highest ratio in the response to the question asking the principal straight motive of leisure activity. 5) 75$\sim$80% students considered the leisure activity as an important means to maintain health and physical fitness. 6) Though most students participated in the activities with friends, 30% of the students answered that they participate by themselves. 7) It was shown that 51% and 40% of KSA male and female students, 40% of MLA male students and 48% of MLA female students participated in leisure Activity planlessly. 8) The average leisure time of the most students was less than 2 hours a day and Male students were observed to have more leisure time than female, and KSA students to have more time than MLA students. 9) In weekdays, KSA's male students enjoyed mostly the sport for leisure activity, but taste-culture activity showed the highest ratio in the case of MLA students and KSA female students. 10) In the case of male students, 38% of KSA and 54% students of MLA did not play computer game at all, and 70% of the female students in total did not play computer game. Also, the proper control-method was in need because the result showed that KSA's male students spent more time in playing computer game than MLA's male students did. 61% of KSA female students and 53% of MLA female students answered that they did not play compute game at all during weekends. Whereas It showed that 26% of KSA male students played computer game over 3 hours during weekends. 11) The biggest reason for being unable to participate in the leisure activity was the insufficiency of time due to homework or studying for quiz. The laziness also showed high percentage of 19$\sim$25% varying between the groups. 12) The life satisfaction of KSA male students was visibly higher(p<.05) than that of MLA male students but the significantly difference wasn't shown in the case of female students.

The effective probability-based tile pre-fetching algorithm and the collaborative cache replacement algorithm are able to reduce the response time for user's requests by transferring tiles which will be used in advance and determining tiles which should be removed from the restrictive cache space of a client based on the future access probabilities in Web GISs(Geographical Information Systems). The Web GISs have multi-level abstracted data for the quick response time when zoom-in and zoom-out queries are requested. But, the previous pre-fetching algorithm is applied on only two-dimensional pre-fetching space, and doesn't consider expanded pre-fetching space for multi-level abstracted data in Web GISs. In this thesis, a probability-based pre-fetching algorithm for multi-level abstracted in Web GISs was proposed. This algorithm expanded the previous two-dimensional pre-fetching space into three-dimensional one for pre-fetching tiles of the upper levels or lower levels. Moreover, we evaluated the effect of the proposed pre-fetching algorithm by using a simulation method. Through the experimental results, the response time for user requests was improved 1.8%∼21.6% on the average. Consequently, in Web GISs with multi-level abstracted data, the proposed pre-fetching algorithm and the collaborative cache replacement algorithm can reduce the response time for user requests substantially.

The purpose of this study was to identify the compensatory adaptation of dentoalveolar structure according to the various skeletal relation through the statistical correlation between the anteroposterior, vertical skeletal and dentoalveolar relation. For this study, the sample were consisted of 101 adult subjects (51male and 50 female, mean age; male 23.6 years, female 21.5 years) who had good occlusion with the range of normal overjet and overbite and acceptable Angle's class I molar relationship which had not been related orthodontically The results were as follows : 1. Even though acceptable normal occlusion, the range of measurements which represent anteroposterior, vertical skeletal relation and dentoalveolar relation were very wide. 2. Upper and lower incisor axis were significantly correlated with anteroposterior skeletal relation, which means the mote lingual inclination of upper anterior teeth and the more labial inclination of lower anterior teeth according to the more anterior position of mandible to the maxilla (P<0.01). 3. Upper and 1ower anterior alveolar bone height was statistically correlated with the lower anterior vertical skeletal height. 4. Upper and 1ower alveolar bone height were not correlated with anteroposterior skeletal relation (P>0.05). 5. The correlation between the incisor axis and vertical skeletal was more closely related in upper anterior teeth than the lower anterior teeth. To summarize the above results, even though acceptable normal occlusion, skeletal and dentoalveolar relation was very widely ranged, and there were close relationship between the anteroposterior skeletal relation and the inclination of upper and lower anterior teeth and between the vertical skeletal relation and upper and lower anterior alveolar bone height. These finding can be concluded as compensatory adaptation to the different skeletal relationship.

The social welfare service is expanding to different field as the social welfare budget is increasing. By this opportunity, it needs to make clear of the basis of argument that the necessity of development of korean government's support and aid by social policy should be worked. Welfare economics perspective, this study used by the operating expenditure in welfare facilities for the elderly old people to effect social benefits to be gained, in other words, business value analysis. Local elderly people, provide opportunities to participate in the economic activities of the family welfare services offered to attainment of the elderly welfare policy, and provide disease prevention and health promotion opportunities, to enhance the satisfaction of life, including a wide range of impact will cause. In this study, elderly people use the welfare facilities for the elderly when they get the benefits by applying the AHP analysis techniques operating value was calculated. Elderly Welfare Center operated by the result of applying P senior welfare center Case of the metropolitan area value was estimated 248.4 billion won. Contribute to the effects caused by the cost factor of the analysis was 23.1% of the total 57.3 billion won. Independence elements 57.6 billion (23.2%), the analysis of the therapeutic elements 133.4 billion (53.7%) of the net was. The result of the study anticipates the role of basic research material for the necessity of intervention, support, and aid by the Welfare facilities for the elderly field at this point in time where the welfare budget policy in terms of universal social service is reinforced, rather than the trend, until recently, of realizing the Elderly welfare budget and service as Consumption expenditure and consumable benefits and the function of performing the effect and evaluation in tentative action of social conflict.

To identify the eating behaviour of customers at a hotel buffet styled restaurant, a survey was conducted. The age range of the respondents was 6 through 70, but consisted mainly people in their twenties, thirties, and forties of the respondents, 65.1% were female. The occupation ranged from student 30.3%, housewife 27.2%, office worker 19.3%, professional 17.3%. 43.9% of respondents visited buffet styled restaurant 1 to 2 times every three or four months. Some respondents had a positive opinions: they had many choices in food selection, they could take and choose as much as they wanted, the appearance and the arrangement of the food was great, etc. But some also had negative attitudes(i.e. unhappy with self service and expensive prices). Of the respondents, 31.1% said they visited the buffet styled restaurant was for family parties and the average number of the party member was $9.3{\pm}4.3$. The average time period of eating was 1 hour $32{\pm}26$ minutes. The average frequency of taking food was $3.7{\pm}1.2$. The average frequency of taking food after satiety was $1.2{\pm}0.8$. The first selection of the buffet service food was soup 23.9% of the respondents and salad 23.9%. Females chose more of the soups and salads the males chose more of the meats and seafoods. The standard of food selection was 70.7% of 'my favorite'. This tells customers' low cognition level of desirable food selection and the order of a meal. 64.0% of the respondents responded overeating, from mild and extreme. We think that information on nutrition education and health problems are necessary. For better service, 82.9% wanted to lower the price by decreasing similar items. Respondent wanted; one, to increase more Korean food items and make a traditional Korean buffet styled restaurant, two, to use more seasonal food and decrease the redundant food items to reduce the price, and three, to have different price rates according to the age or gender of the grown ups.

Objectives: This study was conducted to understand the status of influenza vaccination in some rural communities and to apply the results to formulate a counterplan for influenza prevention. Methods: The authors conducted a questionnaire survey from May 26 to May 29, 2003 among the residents in two rural communities: 602 people at the village Gigye-myeon and 965 at the village Cheongsong-gun. For statistical analysis the chi-square test and chi-square for trend method were used. Significance was set a p<0.05. Results: The study group contained 722 (46.1%) males and 845 (53.9%) females. In response to the question 'Influenza vaccination must be taken every year', 845 people (86.0%) replied 'Yes'. In response to the question 'Influenza vaccination can prevent cold', 224 people (20.8%) replied 'No'. The rate of influenza vaccination increased every year from 2000 to 2002 (p<0.05) and was lower for those under sixty-four than for those over sixty-five. In response to the question 'Plan to receive influenza vaccination in 2003', 531 people (52.8%) responded they will have influenza vaccination. Conclusions: Many people had a wrong perception about influenza vaccination. Therefore, their wrong perception must be corrected by a publicity campaign. The rate of influenza vaccination for those from over fifty to under sixty-four should be increased by public policy because they are as susceptible to influenza as those over sixty-five. This study produced meaningful results from the investigation into the status of influenza vaccination for the residents in rural communities and these findings can be utilized in the formulation of future influenza vaccination policy.

Objectives: Depression is a major health concern that can be life threatening if not recognized and treated early. However, there is few report on the depressive disorder of Hansen disease patients in Korea. Therefore, the authors executed this study in order to check factors related to a depressive disorder of a Hansen disease patients and compare with factors to reach to a depressive symptoms of ordinary people with studying their life state and the trouble that Hansen disease patients were currently experiencing Method: The authors surveyed depressive symptoms using self-reported questionnaires in 74 Hansen disease patients and 84 controls. The severity of depressive symptoms was measured using Korean Form of Geriatric Depression Scale (KGDS) score. Result: Positive rate of depressive disorders among Hansen disease patients was 70.3% and that the referents was 31.0%. There is significant difference positive rate of depressive disorders between Hansen disease group and the referents in the factors such as gender, age, frequency of going out, familial type, and familial income. Depressive disorder of Hansen disease group was associated with sex, familial income. According to the multiple logistic regression, the odds ratios of the Hansen disease group versus referents, gender, familial income, frequency of going out were significant (p<0.05). Conclusion: Hansen disease patients had statistically significant higher depressive symptom score than the referents. Also, Hansen disease patients who have lower familial income were more likely to have depressive disorders. Therefore, Economical supports and policy are required for the Hansen disease patients.

The functions of urban open space, which embraces community revitalization, are diverse. It is the means of public healthcare, learning centers for children, hub of arts and cultural programs, as well as promoter of urban tourism. However, in-depth discourse and research on the topic of urban open spaces has been limited so far. Hence, this study aims to investigate the motivations and satisfaction of visitation based on four representative waterfront open space in Seoul; Cheongyecheon Waterfront, Seoul Forest Park, Seonyudo Park and Banpo Hangang Park. The methods of study are literature review, observation investigation, and questionnaire survey. The findings are analyzed through the Exploratory Factor Analysis, Reliability Analysis, ANOVA Analysis and Regression Analysis by SPSS 18.0. The results of the study are as follows. First, urban waterfront open spaces in Seoul has 5 factors of visitor motivation; community amenity, nature access, cultural and educational assets, aesthetic enjoyment, and lastly means of escape. Second, factors of recognizing urban waterfront open spaces as community amenity and nature access indicate meaningful differences in visitor's perception by spatial characteristics. Third, distances between the destination and the visitor's residence influence significantly their perceived motivation. Close-range visitors perceived nature access as a principal factor, whilst medium to long-range visitors perceived visitation for aesthetic purposes more importantly. Lastly, the will to escape was shown as the influential factor in visitor satisfaction. Visiting open spaces for the enjoyment of nature and aesthetic purposes were factors that also closely relate to visitor satisfaction. In addition, it was found that there are different visitor motivations that influence visitor satisfaction in accordance with the spatial characteristics of each open space. In summary, it can be said that urban waterfront open space is a hybrid space connected to various types of urban contents beyond daily experiences. It was found that several visitor motivations including community development, design aesthetics, education and culture, entertainment, enjoyment of natural landscape, and relaxation, affect the overall satisfaction of the visiting experience. It is anticipated that the results of the study will be used by the local government in setting up strategies for the creation and management of successful urban waterfront open space, and for those involved in planning and design act as a starting point for spatial programming and amenities arrangement in accordance to the city's tourism and urban marketing approach.

Purpose : Toll-like receptor 2 (TLR2) is critical in the immune response to mycobacterial infections. The purpose of this study was to analyze TLR2 surface expressions and TLR2-mediated tumor necrosis factor-alpha ($TNF-{\alpha}$) and interleukin-6 (IL-6) production in patients with BCG vaccine-associated suppurative lymphadenitis. Methods : Peripheral monocytes were separated from 16 patients with BCG vaccine-associated suppurative lymphadenitis and 10 healthy controls using a magnet cell isolation kit. Monocytes ($1{\times}10^6$ cells/well) were incubated with a constant amount of $Pam_3CSK_4$ ($100{\mu}g/mL$) for 24 hours. TLR2 surface expression on monocytes was analyzed by FACS analysis and TLR-2 mRNA expression was determined by RT-PCR. TLR2-mediated $TNF-{\alpha}$ and IL-6 production were measured by ELISA. Results : In patients with BCG vaccine-associated suppurative lymphadenitis, low TLR2 expression on monocytes ($3.39{\pm}$1.2% versus $4.64{\pm}2.6%$) together with significantly lower TLR2 mRNA expression than in the healthy controls was seen after $Pam_3CSK_4$ stimulation. TLR2-mediated $TNF-{\alpha}$ and IL-6 production in patients with BCG vaccine-associated suppurative lymphadenitis ($TNF-{\alpha}$, $775.5{\pm}60.8pg/mL$; IL-6, $4,645.8{\pm}583.9pg/mL$) were also lesser than that in healthy controls ($TNF-{\alpha}$, $1,098.5{\pm}94.3pg/mL$; IL-6, $6,696.3{\pm}544.3pg/mL$). Conclusion : These findings suggest that low TLR2 expression on monocytes might be associated with increased susceptibility to BCG vaccine-associated suppurative lymphadenitis.
