The purposes of this study were 1) to analyze the preference of leadership style among ${\lceil}$Transformational leadership$\rfloor$ and ${\lceil}$Service leadership$\rfloor$, 2) to examine the differences of the job satisfaction between the high level of service leadership group and low level of the service leadership group and 3) to testify the hypothesis that the service leadership and its 4 elements (belief, attitude, ability, insight) affect the job satisfaction. The questionnaires were developed to measure the service leadership, the preference of leadership style (transfer-mational leadership and service leadership) and Job satisfaction. The surveys were distributed to 120 managers and employees in the family restaurant in Korea, and 104 questionnaires were responded (response rate: $86.7\%$). The SPSS 12.0 package program was used to conduct the descriptive analysis, correlation analysis, t-test and multiple regression analysis. The result of leadership style preference showed the followers preferred the service leadership $(75.0\%)$ to the transformational leadership $(25.0\%)$. Comparing the job satisfaction of high level of service leadership group and that of low level of service leadership group, the job satisfaction of high level of service leadership group was significantly (p<0.001) higher than that of low level of service leadership group (high level of service leadership group: 4.03, low service leadership group: 3.27, measured on a 5-point likert scale). All three factors of job satisfaction (human factor, service system and company image) in high level of leadership group were significantly (p<0.001) higher than those of lower level of service leadership group. The result of multiple regression analysis presented that the service leadership and it's 4 elements (concept, mind, skill, insight) have significant (p=0.000) effects on the job satisfaction. As a conclusion, we examined theoretical framework of service leadership model and testified the applicability in the field of family restaurants. But the service leadership was the new conceptual theory, so there should be the more empirical studies on managers and employees in the service industry.

In this paper, we consider the problem of regrouping a number of service sites into a smaller number of service sites called centers. Each service site is represented as a point in the plane and has an associated value of service demand. We aim to group the sites so that each group has the balanced service demand and the sum of distances from the sites in the group to their corresponding center is minimized. To solve this problem, we propose a hybrid genetic algorithm that is combined with Voronoi diagrams. We provide a variety of experimental results by changing the weights of the two factors: service demands and distances. Our hybrid algorithm finds better solutions in a shorter computation time in comparison with a pure genetic algorithm.

Survey data were collected from 130 patients in 4 general hospitals in Seoul, and their families. Data were collected during April, 2004, using a questionnaire which included the patient satisfaction scale developed by Jun (2001). Data were analyzed using frequencies, percentages, means and standard deviations, $X^2$ analysis, t-test. The SPSS computer program was used to facilitate analysis. The results of this study are summarized as follows; The total score for satisfaction was high for both groups. For the private caregiver group it was $52.38{\pm}11.08$, and for the public caregiver group, $58.14{\pm}9.64$. This difference was significant(t=-3.391, p=.001). In all of areas, the scores for satisfaction of the public caregiver service group were higher than private caregiver service group, ie. caregivers' attitude, role, confidence, performance, and service charge, and all the differences were significant. In conclusion, it was found that long-term hospitalization of older patients with high dependence resulted in more caregiver service. There were more severe patients in the public caregiver group, but the service charges, additional costs and paid holidays were less. Based on these results, patients and their families were significantly more satisfied with public caregiver service because it was not only less expensive but also had a high quality of service. Thus, caregiver services should be systemized so that patients and their families will get the best quality caregiver service

The major purpose of this study was to develop the nutrition education contents and material through the basic data from the service provider and the consumer. And also, to find out the differences of attitude and needs between the service provider (SP breastfeeding specialist), present consumer (PC, pregnant or lactating women) and future consumer (FC, college women). There were types of questionnaires, which consisted of needs and attitudes toward child and maternal nutrition, as well as the personal characteristics of the study subjects. The subjects consisted of 113 breastfeeding specialists who served at medical related institutions, 197 pregnant or lactating women and 309 college women. The self-administered questionnaires from subjects were collected from October to November 2005 in Seoul and Kyunggi Province. The data was analysed by SPSS Win 12.0, ANOVA and Kruskal-Wallis test. The results of this study were as following: 1) The most Important determining factors on breastfeeding was 'medical specialist's support' (3.51) and the next one was 'knowledge of maternity care practice' (3.39). And the importance score of determinating factors on breastfeeding was significantly different between each group (p < 0.001). The groups of consumer (3.50 at PC and 3.59 at FC) considered the service provider (3.32) more important. The service providers considered a more effective determining factor to be 'husband and family support' and 'peer support' than the others (p <0.001). 2) To compare the effective factors of breastfeeding practices between the three groups, the service providers were more significantly considered than the otters such as 'attendance of intervention program' (p < 0.001). But the PC group considered the most effective factors wis 'mother's job after delivery'. 3) The self-evaluated score of the breastfeeding knowledge was the most high in SP; the score was significantly different between groups. The knowledge score of nutritional aspects in human milk was most highly evaluated. But maternity care practice and public acceptance marked the lower evaluation score than other issues. 4) The desirable types of educational material was mass media, and the next was printed matter such as booklets. Two kinds if consumers preferred DVD or VCR tapes than and the service provider group (p < 0.001). 5) The priority contents of nutrition service PC group wanted the information about infant care more than maternal care (p < 0.05), but FC group's priority was significantly different compared with PC group (p < 0.001). The priority of SP group pointed out the information of practical child care methods. The results showed the needs of nutrition service, education channels, and perception toward effective factors on consumer behavior changes were significantly different between each group. Thus the result of this study may suggest that consumer oriented nutrition service programs must be developed.
