This study aims to understand the conditions for using logistics outsourcing of Korean enterprises, present existing problems, examine factors affecting utility, and analyze the pattern of logistics outsourcing based on contract term, and to ultimately contribute to enhancing competitiveness of logistics enterprises. Through the literature survey 8 factors were identified as three broad factors of corporate strategy, corporate characteristics, and environment. Factor analysis was conducted on the bases of 155 collected data among 400 distributions for 2 months from April to May in 2008. From the result of analysis, the implication and finding can be summarized into three aspects. Firstly, Korean companies value factors relative to corporate strategies as motivating factors for logistics outsourcing. Secondly, Korean companies consider logistics outsourcing depending on how to handle customers' demands and the severity of competition. Thirdly, it was found that product and organization characteristics are perceived as more important when contract term with logistics business is longer. The implications can be observed into two aspects. Firstly once the logistics outsourcing between manufacturers and logistics companies are determined, it was verified that mutual agreement, particular contracts and periodic communications can increase the outcome. Secondly the logistics outsourcing appeared to be different depending on the level of entering to foreign market and resulted in higher performance as well.

The purpose of this study is to identify a potential user's need for use and operational of the elderly day care center and to identify the problems and suggest development directions. The data collection was conducted on 320 ordinary people living in J-do through a questionnaire, and sought to understand the operational status of in-depth interview institutions for the heads and employees of six center. As a result of the analysis, a potential user's ware not aware of the functions and specific roles of day care center, the cost of facilities was covered by the government, and that facilities and the environment were important factors when using the center. In-depth interviews show that the current policy or system is far from reality and does not fit the status or role of the workers and the operational status of the agency, requiring the re-establishment of the on-site system. Based on the research results, the development direction of day care facilities requires active promotion and strengthening of family support for improving and enhancing awareness of day care facilities to citizens at the national level. Second, the quality of nursing services should be enhanced through improvements in facilities and the environment that reflect users' needs. Third, The government should improve the quality of nursing services by improving the poor employment conditions and treatment of workers to fit the reality.

This study aimed at developing a set of question cards for fostering deep understanding and encouraging reasoning about fossils and analyze the characteristics of visitors' communication depending on whether to use the question cards in a fossil gallery. Through several steps, a card set consisted of nine generic questions about fossil exhibitions and guidance for using question cards were developed. Data related to visitors' communications were collected from 18 peer groups (from 5th to 9th grade) visiting the fossil gallery of Gwacheon National Science Museum. Visiting groups' interactions were videotape recorded and transcribed. 'Holding time,' the types of 'actions,' and the types of 'conversation' were analysed. Visitors' actions were divided into three categories: ‘look’, 'speech', and 'motion.' Furthermore, visitors' conversations categorized as 'speech' were subdivided into four patterns: 'enumerative,' 'consensual,' 'responsive,' and 'argumentative.' Using the question cards contributes to increase holding time and most of the visiting actions. Most of the conversation patterns also increased except the responsive pattern. In conclusion, using question cards in a fossil gallery could facilitate concentrated and meaningful visits by enhancing active verbal and non-verbal communications between exhibit and visitor or among visitors, encouraging visitors' reasoning about exhibits, and guiding visitors what and how to focus on exhibits.

Many local governments in Korea provide online services for people to easily access the audio-visual archives of events occurring in the area. However, the current method of managing these archives of the local governments has several problems in terms of compatibility with other organizations and convenience for searching of the archives because of the lack of standard metadata and the low utilization of image information. To solve these problems, we propose the metadata design and machine learning-based automatic indexing technology for the efficient management of the image archives of local governments in Korea. Moreover, we design metadata items specialized for the image archives of local governments to improve the compatibility and include the elements that can represent the basic information and characteristics of images into the metadata items, enabling efficient management. In addition, the text and objects in images, which include pieces of information that reflect events and categories, are automatically indexed based on the machine learning technology, enhancing users' search convenience. Lastly, we developed the program that automatically extracts text and objects from image archives using the proposed method, and stores the extracted contents and basic information in the metadata items we designed.

The low quality fresh ginseng was extracted by water at $80^{\circ}C$ and 240 bar for 20 min (HPE, High pressure extraction process). The cytotoxicity on human normal kidney cell (HEK293) and human normal lung cell (HEL299) of the extracts from HPE showed 28.43% and 21.78% lower than that from conventional water extraction at $100^{\circ}C$ in adding the maximum concentration of $1.0\;mg/m{\ell}$. The human breast carcinoma cell and lung adenocarcinoma cell growth were inhibited up to about 86%, in adding $1.0\;mg/m{\ell}$ of extracts from HPE. This values were 9-12% higher than those from conventional water extraction. On in vivo experiment using ICR mice, the variation of body weight of mice group treated fresh ginseng extracts from HPE of 100 mg/kg/day concentration was very lower than control and other group. The extracts from HPE was showed longer survival times as 35.65% than that of the control group, and showed the highest tumor inhibition activities compared with other group, which were 70.64% on Sarcoma-180 solid tumor cells. On the high performance liquid chromatogram (HPLC), amount of ginsenoside-$Rg_2$, $Rg_3$, $Rh_1$ and $Rh_2$ on fresh ginseng were increased up to 43-183% by HPE, compared with conventional water extracts. These data indicate that HPE definitely plays an important role in effectively extracting ginsenoside, which could result in improving anticancer activities. It can be concluded that low quality fresh ginseng associated with this process has more biologically compound and better anticancer activities than that from normal extraction process.

Recently there are difficulties in management of golf courses because of an ever increasing demand for golf as a leisure sports. Hence natural minerals as an amendment could be applied to improve and manage the physicochemical properties of the golf course soils in an environment-friendly way. In this study, quartz porphyry, which has been shown to be a good soil amendment for crop production, was tested for its effect on physicochemical properties of the golf course soil, growth of creeping bentgrass (Agrostis stolonifera) and changes of soil microbial communities in the soil. In general, amendment of 20% quartz porphyry into the soil turned out to be most effective in enhancing a proper growth of the grass leaves and roots. DGGE profile data showed that eubacterial species richness was also the highest at this level of the mineral treatment in which Actinobacteria and ${\alpha}$-Proteobacteria were the dominant phyla. This appeared to be attributed to a low level of soluble organic matter content and decreased concentration of cations such as $Ca^{2+}$, $Mg^{2+}$, and $K^+$.

The main objective of this paper is to investigate the factors affecting organizational citizenship behavior of hospital employees, and based on the investigation, to suggest some implications for effective human resources management of hospitals. For this purpose, physical therapists were selected as the subject of the research. Using their individual characteristics, job characteristics, professionalism and group cohesiveness as the variables affecting organizational citizenship behavior, an empirical model was constructed and tested. A survey was conducted through structured and self-administered questionnaire for the physical therapists working at hospitals of Busan-Kyongnam area, and data from 240 therapists were utilized in the final analysis. Major results of the empirical analysis are as follows: First, perception on professionalism and the degree of organizational citizenship behavior were higher for male, older, relatively more-educated and higher-grade employees. It is necessary to develope some measures to educate and motivate the employees who are in lower state of professionalism and organizational citizenship behavior. Second, among the individual characteristics, need for growth was found to have significant, positive influence on professionalism and group cohesiveness, but no direct effect on organizational citizenship behavior. On the other hand, extroversion had direct, positive effect on organizational citizenship behavior, as well as on professionalism and group cohesiveness. This result suggests that personnel selection and personality education should be conducted carefully. Third, job characteristics appeared to have very large, positive effect on professionalism, but not directly on organizational citizenship behavior. Fourth, professionalism was found to have very large, positive influence on group cohesiveness and direct, positive effect on organizational citizenship behavior. This implies that enhancing professionalism of physical therapists can strengthen organizational citizenship behavior in hospitals, and hence top management should actively support the programs for job re-design, skill education and quality improvement to enhance professionalism of their employees. Fifth and last, as an intervening factor, group cohesiveness appeared to have the largest, direct, positive effect on organizational citizenship behavior. It is, therefore, important for top management to improve group cohesiveness by exploring ways toward greater harmony and solidarity among the members of physical therapy department.

A research tool was used questionnaire that was proved reliability and validity. It was prepared with totally 50 questions such as 12 items for subjects' general characteristics, 18 items for job satisfaction measurement, and 20 items for life quality measurement. An analysis of the collected data was computationally processed by using SPSS Win 17.0 program. An analytical technique was made by using statistical techniques such as frequency & percentage, T-test or One-way ANOVA analysis. The following are the analytical results of the collected materials. Results: As a result of analyzing research subjects' job satisfaction level, there was significant difference(P<0.05) in items of religion, hobby life, working environment, and rest time out of daily work. The whole mean in job satisfaction was indicated to be relatively high with 3.13. However, job satisfaction with social recognition, salary, and safety was indicated lowly. As a result of analyzing research subjects' life quality level, there was significant difference(P<0.05) in items of religion, hobby life, working environment, and rest time out of daily work. The whole mean in quality of life was indicated to be relatively high with 3.10. However, the satisfaction was indicated lowly in the whole life quality and the life environment sphere. As a result of analyzing correlation between job satisfaction and life quality, all variables were indicated to be positive correlation in high significance level, thereby having been indicated that the higher job satisfaction leads to the higher life quality. Conclusion: As a result of research, the dental technicians' job satisfaction was indicated to have high correlation with quality of life. An effort is judged to be necessary for establishing fair compensation system, improving welfare policy and enhancing social recognition and position in order to promote dental technicians' quality of life.
