As compared with the gender differences in the achievement of mathematics of the PISA 2009, the results of this study on the PISA 2012 show that the achievement of male students sharply increased, while that of female students maintained the status quo. Based on the premise that this result is derived from the ratio differences between male and female students of high level, this study analyzed the educational context variable effects on the achievements of gender differences observed between male and female students of high level. In particular, this study inquired into the factors which influence the gender difference, by analyzing the identical variables regarding Singapore and Finland of which the achievement of female students registers high among other top high-ranking countries of the PISA 2012. Hence, the binominal logistic multi-level analysis was conducted in order to consider the characteristics of hierarchical structure of PISA, and to compare the features of the educational context variable effects between the high level (above level 5) by country and the highest level (above level 6) by group. The analysis results are as follows: in terms of after-school learning time realized either in private lessons and private institutes, no significant effects were shown in any of the students of these three countries. In terms of after-school homework time, the students of Korea and Singapore gave significant influences on the probability which would be included in the group of high level or the highest level. In particular, regarding the variables which influence the probability of inclusion of Korean female students in the group of high level or the highest level, they correspond to "Homework set by teacher", "Attitude toward school: learning activities", "ESCS of School" and "Teacher-student relations". And "Cultural possessions at home" gave main influences on the probability of inclusion of the female students of Korea, Singapore and Finland in the group of the highest level.

The sensing of a stack coolant deficiency is very important in that cooling performance of a fuel cell, overheating prevention of a stack or coolant heater. This paper explains the performance comparison between the coolant contact/noncontact level sensors and coolant deficiency sensing logic using the pressure sensor in a stagnant or circulating flow. Throughout the comparison, the pressure sensor is more suitable than the other sensors in terms of the precision, fast response, sensing frequency. After the experiment, the pressure sensor is equipped to an FCEV(Fuel Cell Electric Vehicle) to verify sensing definitely. There was no miss-sensing using pressure sensor while FCEV runs in the conditions of the paved road and cross country road.

One of the major functions of rural extension services is to transfer agricultural technologies and information, and advanced new agricultural techniques developed by research institutes, which are meaningful when they are transferred to farmers for practicl application. Information materials can be transferred in the form of newspapers, radio and television broadcasting, printed materials, audio-visual aids, and public communication networks. Agricultural information systems in the era of localization should be oriented toward county extension services, and the following points should be emphasized for more effective dissemination of agricultural technologies : 1) Central organization of the Rural Development Administration should put more emphasis on the production and dissemination of agricultural information to support activities of extension agents at the county level. 2) An Agricultural information center should be established for more effective collection, analysis, processing, production and dissemination of various agri-related information. 3) An advanced and unified network system should be adopted for more accuate and rapid information flow throughout the country, and reinforcement of manpower and facility at the county level should be emphasized for more effective dissemination of agricultural information.

Regardless of which country, all public libraries need facilities, collections, and funds. But how well the library system succeeds depends on the staff committed to providing the highest possible level of service to the community. The public library, therefore, should employ the appropriate number of full-time staff. In order to warrant such a work force, this study analyzed the juridical justification, logical validity, realistic fitness, and usefulness of current legal and recommended staffing standards. This study also suggested the revisions of total space of buildings and collection size as crucial variables for library staffing, division of legal service populations, basic staffing level, and additional staff in proportion to service populations for public libraries in Korea.

Objective: The aim of this study is to develop new K-OWAS on the basis of the anthropometry of Koreans considering works in shipbuilding and heavy industry for evaluation whole-body working postures. Background: Work Related Musculoskeletal Disorders(WMSDs) were a leading cause of sick leaves and injuries in the industries of our country. Especially, awkward working postures and handling of heavy weight are known as a main cause of WMSDs. OWAS, RULA and REBA are much used as the method for evaluating the awkward working postures. OWAS is the working postures evaluation method that can be used for the evaluation of whole-body working postures. OWAS was the method made based on the anthropometry of the foreigner, working postures and weight does not fit our work state. Method: This method was evaluated considering the anthropometry of the Koreans, working postures and weight in shipbuilding and heavy industry work state in Korea. Results: Correlation of action level of OWAS and subjective discomfort for each body parts were not statistically significant($p{\geq}0.1$). But correlation of action level of K-OWAS and subjective discomfort for torso and waist were statistically significant($p{\leq}0.1$). Conclusion: K-OWAS was suitable in the evaluation of upper body including torso and waist. Application: New method for whole-body working postures from this study prevent WMSDs and help improvement of working environment and design of working method.

Purpose: The purpose of this study was to identify the factors affecting the unmet healthcare needs of married immigrant women. Methods: This study was a secondary data analysis using data from the 2009 National Survey of Multicultural Families. Data collected from 58,735 married immigrant women who had spouses were analyzed using descriptive statistics, Chi-square test, and logistic regression. Results: Overall, 9.9% of married immigrant women have unmet healthcare needs. The significant predictors related to unmet healthcare needs were young age, high level of education, employed, country of origin, long period of residence, low income, uninsured, urban area, low level of subjective health status, and illness experience over past two weeks. In particular, four variables (long period of residence, low income, subjective health status, and illness experience over past two weeks) significantly predicted unmet healthcare needs for women from all countries of origin. Conclusion: The results of the study indicate that common predictors related to unmet healthcare needs of married immigrant women are a long period of residence, low income, subjective health status, and illness experience over past two weeks. Therefore intervention strategies to decrease unmet healthcare needs should focus on these significant predictors.

The current networks do not disclose information about a management domain due to scalability, manageability and commercial reasons. Therefore, it is very hard to calculate an optimal path to the destination. Also, due to poor information sharing, if an error occurs in the intermediate path, it is very difficult to re-search the path and find the best path. Hence, to manage each domain more efficiently, an architecture with top-level path computation node which can obtain information of separate nodes are highly needed This study aims to investigate a federation of a united network around NRN(National Research Network) that could allow resource sharing between countries and also independent resource management for each country. Considering first the aspects that can be accessed from the perspective of a national research network, ICE(Information Control Element) and GFO(Global Federation Organizer)-based architecture is designed as a top-level path computation element to support traffic engineering and applied to the multi-domain network. Then, the federation for the independent management of resources and resource information sharing among national research networks have been examined.

Most literature on the "comfort women" social movement focuses on the case of Korea. These works tend to transpose the meanings generated by South Korean organizations onto the transnational network, assuming certain homogeneity of repertoires and identities among the different social actors that comprise this network. Even though there is some degree of consensus about demands, repertoires, and advocacy strategies at the international level, does this same uniformity exist at the national level? In each country, what similarities and differences are present in the laboratories of ideas, relationships, and identities of social actors in the network? Symbolically and politically, do they challenge their respective societies in the same way? This article compares this social movement in South Korea, China, and Taiwan. My main argument is that the constitutive base for this transnational network is the domestic actions of these organizations. It is in the domestic sphere that these social actors reinforce their agendas, reinvent their repertoires, transform their identities, and expand their submerged networks, allowing national movements to retain their latency and autonomy. Following Melucci's relational approach to the study of social movements, this research is based on a qualitative analysis of institutional documents, participant observation, and open-ended interviews with members of the main social actors.

This paper intends to explore the relationship between financial inclusion and financial stability under the scope of Asian economies. The linkage will be thoroughly investigated with country-level and bank-level data of 42 countries in three separate years: 2011, 2014, and 2017. In this study, an inclusive financial system is assessed by two dimensions: usage of financial services and access to the financial system. Usage of financial services ranges from account to credit, savings and payment services. Access to financial system measures the financial outreach where individuals can use financial services. Meanwhile, financial stability, which proxied by Bank Z-score is regarded as the dependent variable. We apply fixed effects regression and random effects regression to capture the impacts of financial inclusion upon financial stability. To enhance the robustness of the model, the Feasible Generalized Least Squares (FGLS) regression is therefore adopted as the solution for the random effects regression. The empirical findings exhibit an overall weak positive influence of financial inclusion on financial stability. The research results also provide both financial institutions and governments with insightful information, which helps them to have an appropriate financial development strategy, improve the regulatory framework and consequently enhance financial stability for the whole system.

This study examines the differences of enacting models and influential causes of benefit-sharing practices between Korean automobile networks and the Japanese networks. The case study method is chosen for this research because only small numbers of supply networks adopt benefit-sharing practices. I employ semi-structured interviews with managers from four automobile manufacturers and eight of their suppliers in South Korea and Japan. I find that Japanese automobile networks have adopted a higher level of trust-demanding, with a higher level of value-creating models such as supplier development, joint-new-product development. Whereas, the Korean networks have adopted the lower trust demanding, also less profitable models such as supplier's suggestion and buyer's suggestion. In terms of work-related cultural values, I find that Japanese networks emphasized collectivism. Both buyers and suppliers in the Japanese networks are supposed to have common causes. In contrast, Korean networks emphasized individualism. Both buyers and suppliers of Korea generally do not identify that they are common group members with a common cause. I also find that a slight differences of the enacting models and the causes between foreign-owned networks and domestic-owned networks within each country. Foreign-owned networks have adopted lower trust demanding, also less profitable models. The findings demonstrate that the cultural values have a decisive influence on the adoption of benefit sharing models for the networks in Japan, and South Korea.
