Purpose: This study was conducted to examine differences in health care utilization and related costs between before and after the introduction of the designated doctor system, and to find out factors making the differences. Methods: Data were collected from 200 medical aid beneficiaries having one or more chronic diseases, registered in the designated doctor system during the year of 2012, and the relationship between the use of health services and claimed medical expenses was analyzed through paired t-test and multiple regression analysis using the SPSS 18.0 program. Results: There was a decrease in the number of total benefit days and the number of outpatient and medication days, but some cases showed an increase after the designation of medical institution. In general, hospital stay increased after the introduction of the system. However, the number of medical institutions utilized was reduced in most cases after designation. Conversely, medical expenses increased in most cases after the designation of medical institution. Conclusion: These results suggest that a detailed scheme to designate medical institutions should be made in consideration of the seriousness of illness and classification of medical institutions not only for the beneficiaries' enhanced health but for the effective management of medical aid fund.

Purpose: The purpose of this study was to determine factors affecting the burden on employment of occupational health care providers as well as to develop strategies to reduce burden on employment of them in the middle size manufacturing enterprises. Methods: The target population of this study was 123 managers working in the middle size manufacturing enterprises. The study questionnaires were selected, as theories and literature suggested, for explaining employment burden, general characteristics of participants and occupational health providers, general characteristics of companies, evaluation of occupational health provider's role and burden score. Results: The mean of employment burden score of manager was 2.2. There was a significant difference in the employment burden scores, manager's age and education, and occupational health provider's age, type of work, certification, and employment status. Also there was a negative relationship between employment burden scores and occupational health provider's role scores (need, role, satisfaction, and benefit). In the results of the standard multiple regression analysis, manager's need scores on occupational health providers were significant predictors of the employment burden scores. Conclusion: It is necessary to change the manager's perception to promote employment of occupational health providers.

The purposes of this study were 1) to identify determinants of exercise behavior 2) to determine theoretical frameworks that were used in other research 3) to investigate the limitations of exercise research. seventy six research papers, published between 1984-1999, were selected by searching Medline for this study. Research subjects, determinants of exercise behavior, exercise measurement, the design of studies, statistical method and theoretical background were examined. The results are as follows. 1. On the research subjects, most research papers studied healthy adults. 2. Thirteen variables were identified that were used more than 5 times in various researches were self efficacy, barrier, social support, benefit, physiological characteristics, habit, personality, intention, health status, motivation, subjective norm, attitude, and affect. The most frequently supported determinant was self efficacy, the second one was social support, the third was affect and so on. But few research papers found any significant relationship between subject norms or attitude and exercise. 3. On exercise measurement, only 22.4% of research papers considered intensity, duration, frequency as elements of exercise, and 64.5% of researches were assessed by self-reported questionnaires. 4. In research design, 80.3% of research papers were survey type research. The most frequently used statistcal method was Regression. 5. 44.8% of research papers were done without any theoretical basis. Based on the above findings the following suggestions are made : 1. Research which includes diverse populations with different levels of health status needs to be studied. 2. Determinants of exercise may be dynamic and varing in their influence, therefore, stages of exercise behavior and processes of change need to be studied. 3. In research design, more prospective, longitudinal studies are needed to identify determinants of exercise habits. 4. It is necessary to develop a reliable, valid exercise measurement tool. 5. Studies are needed to develop a theoretical framework for exercise behavior.

The purpose of this study was to analyze the dimensions of clothing benefits sought of male and female consumers in their twenties. It also aimed to investigate the demographic characteristics associated with customers types and the relationship among the related variables by the consumers types. The data were analyzed by factor analysis, one-way ANOVA, Duncan test, cluster analysis, and $X^2$-test. The results of this study are as follows: 1) The clothing benefits consisted of five factors, which were the pursuit of style, individuality, popular brand, vogue, and practicality. Based on these five factors, respondents were classified into four consumer types, which were style-and-trend-oriented, practicality-oriented, popular brand-oriented, and fashion indifference consumers. 2) In terms of the demographics, there were significant differences in age, gender, and total income among the consumer types of clothing benefits. 3) There was a significant difference in single brand loyalty in terms of the consumers types of clothing benefits. The popular brand-oriented group showed the highest mean in the single brand loyalty, while the practicality-oriented group did the lowest. 4) There were significant differences in the selection of the stores among consumers types of clothing benefits. Specifically, the style-and-trend-oriented group the most selected department stores, while practicality-oriented group chose fashion outlets or online shopping malls the most. Additionally, in terms of the information sources, the style-and-trend-oriented group the most frequently used magazine ads, while the popular-brand-oriented group preferred commercials on TV or radio, direct mail, or flyers from department stores. On the other hand, the fashion indifference group the most frequently used mass media.

많은 XML 응용들은 XML 문서에 대한 질의 언어로 XPath 패턴을 사용한다. XPath 패턴들 사이에는 포함 관계가 존재할 수 있으며, 하나의 XPath 패턴이 다른 XPath 패턴을 포함하는지를 결정하는 문제를 포함 문제라고 한다. 포함 문제는 많은 응용들에서 발생하고 있지만 co-NP complete 문제로 알려져 있다. 한편 XPath 패턴들 사이의 준동형 관계는 포함 관계의 충분 조건이면서 다항 시간에 얻을수 있다. 본 논문에서는 준동형 문제가 포함 문제를 대체하여 유용하게 쓰일 수 있는 응용들에 대해 논의하고, XPath 패턴들 사이의 준동형 정보를 유지하면 많은 이점을 얻을 수 있다는 사실에 대해 논의한다. 그리고 XPath 패턴들 사이의 준동형 관계를 유지하기 위하여 POX(Partially Ordered Set of XPath Patterns)라는 래티스 구조를 제안하고, 그것을 유지할 수 있는 알고리즘을 개발한다. 알고리즘 분석을 보면 알 수 있듯이, 본 논문에서 제안하는 알고리즘은 다항 시간에 POX를 효율적으로 유지할 수 있다.

International joint ventures are usually formed and managed by domestic companies and foreign investors for the common objectives. They offer an opportunity for each partner to benefit significantly from the comparative advantages of the other. Local partners bring knowledge of the domestic market; familiarity with government bureaucracies and regulations; understanding of local labor markets; and existing manufacturing facilities. Foreign partners can offer advanced process and product technologies, management know-how, and access to export markets. In Korea, joint ventures have been encouraged to usher in foreign investors with foreign currency capital badly needed during the IMF financial crisis. In the meantime, Korean laws and regulations with respect to joint ventures have been largely overhauled to promote foreign direct investment (FDI) both inbound and outbound. They include four types of FDI, i.e., acquisition of foreign stocks, provision of long-term loans, participation in joint operations like resources development, and establishment of foreign offices. From the legal point of view, the formal joint venture agreement must be an offspring of a series of tough negotiations between domestic and foreign partners. They usually stress the long-term relationship with the good will and dedication to each other, and restrict the free transfer of stocks. Both partners are earnestly interested in the ownership and management of the joint venture. So they keep a close eye on the articles of incorporation, changes of business environment, conflict resolution methods, transparency of accounting and other financial matters. When a multinational corporation (MNC) is involved in the joint venture, conflicts over management strategies, marketing and other issues take place more often than not between the MNC and local partners. We have to pay attention to joint ventures, particularly, in China and North Korea. As witnessed in other transition economies, China is eagerly bringing in foreign direct investments for the development of nation's economy. China encourages foreign investors to establish ordinary joint ventures, contractual joint ventures, solely invested foreign capital companies and jointly operated development companies with local partners. In North Korea, however, joint ventures have a different meaning like contractual joint ventures in China, in which North Korean partners have an initiative in the management. Rather, jointly operated companies or simply processing-for-wage companies are recommended in view of the unpredictable legal infrastructure in North Korea.
