The purpose of the study is to investigate the impact on service quality of caregivers. 200 caregivers in 6 elderly care facilities located in J city were instructed to answer structure questionnaires, and the collected data was analyzed by T-test, ANOVA, Pearson correlation, and regression analysis. The results of the study show significant differences in service quality depending on their religion, education level, form of employment, employment period, health status, and access to staff lounge. Work environment shows positive correlation to service quality, whereas job stress shows negative correlation. Variables shown to affect service quality are, from the most powerful to the least, human environment, physical environment, form of employment, employment period, and education level with explanatory power of 42.6%. The results of the study suggest the need for putting in individual effort and improving work environment specifically to unique characteristics of each institution and looking into various ways to intervene in financial support policies in order to promote service quality of caregivers.

In the next generation mobile communications, powerful channel coding is essential in order to obtain high quality multimedia services. Turbo code can achieve good error performance by iterative decoding, but more iterations result in additional computational complexity and delay. Thus, a method to reduce the number of iterations without additional performance degradation is needed. Turbo code with CRC is known to be the most efficient method to reduce the number of iterations. In this scheme, the performance may be degraded by the edge-effect like the conventional turbo code without CRC. In this paper, a method to eliminate the edge-effect is proposed by adopting D-parameter to the conventional s-random interleaver. As results of simulation, the edge-effect of the turbo code with CRC is shown to be successfully eliminated by using the new interleaver designed with D-parameter.

With trend of container ships becoming larger and faster, the environment surrounding ports in North-East Asia is rapidly changing. Korea's largest port of Busan processed more than 10 million 20- feet equivalent containers in 2003, surpassing the 10-million TEU mark for the first time in its three decades of operation. However, the Port of Busan , the world's third-largest port in 2002, was eclipsed by Shanghai since July in 2003. The first massive strike of truckers crippled the Korea's logistics system in May and in September, the Port of Busan suffered from the second strike of truckers and damage by a powerful typhoon. By contrast, the port of Shenzhen in China increased its container-processing volume by 39.9 percent to 10.65 million TEU in 2003, and Shanghai, which passed Busan in terms of container volume in the middle of last year, further consolidated its position as the world's No. 3 port with an annual volume of 11.28 million TEU. After all, Busan recorded an annual container volume of 10.40 million TEU, slipping to fifth in rankings in 2003 and Busan's bid to become a Northeast Asian hub has suffered a further setback as these chinese ports overtook the port of Busan. But the port of Busan is located in the main trunk liking North America, Europe and South-East Asia. Once the project of Busan Newport is accomplished and the railway between South and North Korea is connected to TCR and TSR, the Port of Busan will have the most potential to become the international logistics center as the starting point of the land and sea routes encompassing all over the world.

In order to investigate hydantoinase-producing strain of the genus Streptomyces, 523 strains of Streptomycee sp. isolated from soils were cultivated in various media and conversion activity of the enzyme was measured to DL-5-phenylhydantoin. A number of strains producing hydantoinase were detected and among them, the strain of Streptomyces sp. Y-183 was selected as a most powerful strain to producing the enzyme. The optimal culture conditions for the production of hydantoinase of the strain were studied, and it was found that almost all hydantoinase activity was produced in the cell fraction. The maximum activity of the enzyme, 17.8 unitstg of dried cells weight, was obtained when the strain was cultured at $30^{\circ}C$ for 72 hr in a medium containing 1.0% of glycerol. 0.5% of yeast extract. 0.5% of soytone, 0.5% of beef extract, 0.6% of KCI, 0.002% of $K_2HP0_4, 0.25% \;of \;CaC0_3, \;0.0002% \; of \; ZnSO_4, \; 0.0002%\; of\; FeS0_4$, and 0.4% of uracil as an inducer, and the pH of culture broth was adjusted ranging from 7.0 to 7.5.

The purpose of this study was to investigate how parental childrearing behavior and children's sibling relationships are related to children's self-esteem. 440 middle class families consisting of two children and their parents were the subjects of this study. The research instruments included a childrearing behavior questionnaire, the Sibling Relationships Questionnaire (Furman & Buhrmester, 1985), and the Self-Perception Profile for Children (Harter, 1985). Analyses of the data included correlation analysis, canonical correlation, regression, stepwise multiple regression, and MANOVA with stepwise discriminant analysis as the follow-up test. The most powerful predictors of children's self-esteem were the Warmth-Acceptance of childrearing behavior and the Warmth-Closeness of sibling relationships. The self-esteem dimension was best predicted by parental childrearing behavior and by children's sibling relationships was Global Self-Worth. Behavioral Conduct was best predicted by the Rejection-Restriction factor of childrearing, and by Conflict (for boys) and Rivalry (for girls) factors of sibling relationships. Children's self-esteem was related more strongly to the Warmth-Acceptance and the Rejection-Restriction of opposite-sex parents. The effects of Permissiveness-Nonintervention were stronger in same-sex parent-child dyads. Parental childrearing behaviors accounted for boy's self-esteem better than girl's with the exception of Behavioral Conduct. Sibling relationships accounted for girl's self-esteem better than boy's. The $2{\times}2$ MANOVA revealed interaction effects of parental childrearing behaviors and sibling relationships on children's self-esteem. Two factors of Rivalry and Conflict in sibling relationships and all three factors of childrearing behaviors showed significant interaction effects, The childrearing factor of Permissiveness-Nonintervention and the sibling factor of Rivalry, which were relatively weak predictors of self-esteem when acting alone, gained power in explaining children's self-esteem within the interactional context.

The grandmother role may be an important support network for dual-earner families and become more saliency among those children who are living with their grandmothers than those who are not. The purpose of the present study was to investigate the effects of family structure characteristics on children's solidarity with their grandmothers and grandmothers' effects on grandchildren's self-esteem. Questionnaire data were collected from 429 grandchildren in the fifth and sixth grades. The major findings showed that (1)Solidarity between grandmother and grandchild in dual-earner families was associated with living arrangement. (2)Children's self-esteem in dual-earner families was not related to living arrangements with their grandmother. (3)Factors predicting solidarity between grandmother and grandchild and the grandchild's self-esteem differed by living arrangement. Solidarity between grandmother and grandchild was explained by grandmother-mother relationships, health of grandmother, parent-children relationship and occupational status of father for children living with their grandmothers. For those children not living with their grandmothers, grandmother-mother relationship, the educational level of father, families' economic level, parent-child relationship and health of the grandmother were significant predictors of grandmother-grandchild solidarity. (4)The regression of predictor variables on self-esteem for children living with grandmother revealed that grandmother-grandchild solidarity was the most powerful predictor, followed by occupational status of father, the educational level of mother, economic status of the family and parent-child relationship. For those children who were not living with grandmothers, parent-child relationship, economic status of the family, grandmother-grandchild solidarity and the educational level of the mother were also significant factors in that order.

Recently, utilization of mobile Internet services is rapidly increasing. To properly accelerate the vitalization of mobile Internet usage, we have to know exactly about the factors affecting potential users' value recognition and intention to use. Technology acceptance model (TAM) is one of the most powerful reference framework for the individual user's adoption of IT innovations. This research borrowed core concept of TAM, and tried to explain users' intention to use mobile Internet by understanding the direct and indirect effects of subjective norm and perceived usefulness. To increase the explanatory power of the model, this paper introduced personal innovativeness as a key moderator variable. The research findings include; i) subjective norm has strong positive influence on perceived usefulness and intention to use, ii) perceived usefulness has positive influence on intention to use, iii) the influence of subject norm is greater than that of perceived usefulness, iv) positive influence of subjective norm on the perceived usefulness and intention to use are significantly stronger in the case of low personal innovativeness sub-group than the case of high personal innovativeness sub-group, and v) high personal innovativeness sub-group have shown strongly positive influence of perceived usefulness on the intention to use while there is no such significant relationship in the case of low personal innovativeness sub-group. Based on these findings, this paper proposed several guidelines to increase the adoption and the usage of mobile Internet; i) word-of-mouth is extremely important, ii) to form a good word-of-mouth, it will be very important to make early adopters and heavy users have positive direct experiences of using mobile Internet.

The subjects of this study were 150 admitted patients in a hospital. The data was collected with Nursing Service Satisfaction Scale developed by Tomas(1996) and modified Nurse's Nursing activity styles Scale developed by Coeling(1993). The results were as follows: 1. The mean score for the level of nursing service satisfaction was 65.00(SD=14.10). The mean score for subcategories of nurse's nursing activity styles were as follow; work difficulties management 9.47(SD=2.02), effective work attitude 23.53(SD=3.14), interpersonal relationship 48.82(SD=6.18), keep regulation 23.24(SD=3.62), professional values 48.28(SD=5.27), and professional development 24.41(SD=3.07). 2. The correlations of nursing service satisfaction and subcategories of nurse's nursing activity styles were revealed a positive significant correlation; work difficulties management(r=0.17, p=0.03), effective work attitude(r=0.44, p=0.00), interpersonal relationship(r=0.51, p=0.00), keep regulation(r=0.44, p=0.00), professional values(r=0.31, p=0.00), professional development(r=0.30, p=0.00). 3. Stepwise multiple regression analysis revealed that the most powerful predictor of nursing service satisfaction was effective interpersonal relationship. A combination of effective work attitude, work difficulties management account for 38% of the variance in nursing service satisfaction of the patient in a hospital. In conclusion, this study revealed that the effective work attitude, interpersonal relationship, and work difficulties management in nursing activity were important factors to improve the level of nursing service satisfaction.

Persons with disabilities have increased and among others, number of them in the community is at the high proportion. But they have a difficulty in physical, psychological adjusting and they don't be offered appropriate, sufficient rehabilitation services. Therefore, Community-Based Rehabilitation Services in Health Center be needed. With these backgrounds, this study was conducted to examine factors in relation to job performance of community-based rehabilitation program in Health Centers, and the factors are characteristics of district nurses, internal factors, external-environmental factors. This study provides guidelines for effective management for rehabilitation program. Subject in this study were 122 Health Centers randomly chosen. Data were collected from September, 16, 1998 to October, 9, 1998, and the data for analyses were ones of 105 respondents. The instrument of this study was job performance of community-based rehabilitation program is modified WHO guidelines. Credibility of instruments was 0.73-0.95 in main study. The summary of results was as follows. First, the mean of job performance of com munity-based rehabilitation program was 2.33 of full score 4.00. Significant differences were not obtained on the job performance among areas. Second, stepwise multiple regression analysis revealed that the most powerful predictor to job performance was community-based health program. The number of volunteer workers, the score of cooperation with other institution, the number of visiting nurse, the number of facilities for person with disabilities are accountable factor to the job performance of community-based rehabilitation program. In conclusions, for all the people with disabilities, Health Centers are necessary to promote community-based rehabilitation program and to increase participation of community residents and to cooperate with other institution.
