  • This study attempts to find the relationship between achievement of environmental industry and development of financial sector by analyzing cross-sectional data for OECD countries. Development of financial industry has a positive effect on environmental industry. Green financing also affects improvement of environmental quality. Demand for environmental quality is positively influenced by GDP per capita, while financial crisis has a bad effect on environmental performance. Government-led green financing in Korea has a major role in the Korean environmental policy for years. While market-oriented green financing improves the efficiency of regulation, government-led green financing may delay internalization of environmental cost due to its subsidizing effect. Further study should include systematic analysis on the scope of green financing and its qualitative attribute and fundamental causality between green financing and environmental improvement.

  • With respect to the Semantic Web proposed to overcome the limitation of the Web, OWL has been recommended as the ontology language used to give a well-defined meaning to diverse data. OWL is the representative ontology language suggested by W3C. An efficient retrieval of OWL data requires a well-constructed storage schema. In this paper, we propose a storage schema construction technique which supports more efficient query processing. A retrieval technique corresponding to the proposed storage schema is also introduced. OWL data includes inheritance information of classes and properties. When OWL data is extracted, hierarchy information should be considered. For this reason, an additional XML document is created to preserve hierarchy information and stored in an XML database system. An existing numbering scheme is utilized to extract ancestor/descendent relationships, and order information of nodes is added as attribute values of elements in an XML document. Thus, it is possible to retrieve subclasses and subproperties fast and easily. The improved query performance from experiments shows the effectiveness of the proposed storage schema construction and retrieval method.

  • The purpose of this study is to explore risk factors affecting the oral health quality of life of non-medical hospital workers. As for the research method, a survey was conducted on 608 workers at hospitals in the metropolitan area from April 20 to July 30, 2021. As research tools, questions related to work loss, oral health status, and oral health quality of life were investigated. For the analysis methods, independent sample t-test, one-way ANOVA test, and hierarchical regression analysis were performed. As a result of controlling exogenous variables, gender(β=0.108), systemic disease(β=0.136), oral health level(β=0.201), and oral health status(β=0.463) were found to have an effect on the quality of life. Initiating regular oral health education for non-medical hospital workers will be of great help to promote oral health and work.

  • Recently, as growing of interest for LBS(location-based services) techniques, lots of works on moving objects that continuously change their information over time, have been performed briskly. Also, researches for NN(nearest neighbor) query which has often been used in LBS, are progressed variously However, the results of conventional NN Query processing techniques may be invalidated as the query and data objects move. Therefore, they are usually meaningless in moving object management system such as LBS. To solve these problems, in this paper we propose a new nearest neighbor query processing technique, called CTNN, which is possible to meet accurate and continuous query processing for moving objects. Our techniques include an Approximate CTNN(ACTNN) technique, which has quick response time, and an Exact CTNN(ECTNN) technique, which makes it possible to search nearest neighbor objects accurately. In order to evaluate the proposed techniques, we experimented with various datasets. Experimental results showed that the ECTNN technique has high accuracy, but has a little low performance for response time. Also the ACTNN technique has low accuracy comparing with the ECTNN, but has quick response time The proposed techniques can be applied to navigation system, traffic control system, distribution information system, etc., and specially are most suitable when both data and query are moving objects and when we already know their trajectory.

  • In Korea, as the elderly population increases, elderly medical facilities and nursing care workers are increasing in labor force, but nursing care workers are avoiding nursing care workers due to poor working conditions and many physical and mental exhaustion of nursing care workers. Therefore, in this study, 284 nursing care workers were surveyed to search resources and to find alternatives to enhance the quality of life of caregivers. The result of research, The first, effected positively on the quality of life in environmental and social on a married women. The more a religion, effected positively on the quality of life in environmental and social, psychological. The higher the salary, effected positively on the quality of life in environmental and social, physical. The second, the support of a Superior effected positively on the quality of life in environmental and physical and the support of a colleague effected positively on the quality of life in social and physical. The third, the support of a Superior moderated by self-efficacy of the quality of life in the social and psychological. This results suggest that can be influential variables the support of social and the self-efficacy as an alternative to burnout of the care workers.

  • The purpose of this study is to examine that basic pension entitlement affects the subjective well-being(SWB) of the elderly. For controlling unobserved heterogeneity, we used fixed effects model for longitudinal data. The data used for this study is KLoSA from 2006 to 2016. The research results are as follows. SWB of non-basic pensioners was higher than for basic pension beneficiaries. Second, when the demographic variables were controlled, SWB of the basic pension recipients was higher then that of non-beneficiaries. Third, the factors affecting SWB were economic satisfaction, marital status, family financial support, employment status, subjective health status, daily life restrictions, gender, and age. Fourth, the effect of basic pension on SWB was positive at the lowest income quartile. The results of this study shows that the basic pension system has a positive effect on the SWB of elderly despite the low benefit level. Therefore, it is necessary to expand the basic pension system to solve poverty problems and improve the quality of life for the aged. Also, various aspects of social support for the low-income vulnerable elderly are needed. Lastly, It was suggested that the benefit level of the basic pension should be raised to have a substantial effect on the low-income class, which is a key policy subject.

  • The purpose of this study was to suggest methods to apply generalizability theory to mathematics teacher evaluation using classroom observations in Korea by analysing mathematics teachers in the U.S. using the instructional quality of assessment instrument as an illustrative example. The subjects were 96 teachers participating in Year 3 and Year 4 from the Middle-school Mathematics and the Institutional Setting of Teaching (MIST) project funded by the National Science Foundation since 2007. The MIST project investigates the following question: What does it takes to support mathematics teachers' development of ambitious and equitable instructional practices on a large scale (MIST, 2007). This study examined data based on both the univariate generalizability analysis using GENOVA program and the multivariate generalizability analysis using mGENOVA program. Specifically, this study determined the relative effects of each error source and investigated optimal measuring conditions to obtain the suitable generalizability coefficients. The methodology applied in this study can be utilized to find effective optimal measurement conditions for the mathematics teacher evaluation for professional development in Korea. Finally, this study discussed limitations of the results and suggested directions for future research.

  • One of the main objectives of National Assessment of Educational Achievement (NAEA), which is implemented by Korea Institute of Curriculum and Evaluation(KICE), is to manage the qualities of National Curriculum. Thus we considered NAEA as the research for educational program assessment and tried to find out how to make NAEA better for achieving that objective. For the purpose of this paper we analyzed the present conditions of NAEA into four perspectives. And then according to each perspective we explored schemes for improving NAEA. In conclusion, we proposed the following; Firstly, in relation to assessing students' understanding of the mathematics contents, the meanings of Achievement Levels have to become much more clear and concrete. in relation to assessing for comparing student' understanding according to mathermatics content areas, the number of items has to be increased for elevating validities of NAEA. Thirdly, in relation to gathering the information about properties which are shown by the students in particular Achievement, it is necessary to think about how to produce items for the purpose in the step of developing items in NAEA. Finally in relation to collecting the data which can be useful for relevance of mathematics contents, it is necessary to make a special group of items for identifying relevance of mathematics contents, and to apply performance assessments on part of the students, not whole students.

  • The purpose of this study is to empirically analyze the mediating effect of job stress and Job engagement in job satisfaction between WFC(Work-Family Conflict) and quality of LMX(eader-member exchange) relationship of married female workers based on JD-R(Job Demands-Resources) model. A total of 945 people were targeted using the 7th panel data from the Korean Longitudinal Survey of Women and a structural equation model was used to verify the causal relationship and mediating effect of each variable using spss 23.0 and AMOS 21.0. As a result of the study, it was confirmed that WFC did not directly affect job satisfaction, and it was found that job satisfaction was negatively affected through job stress related to WFC. It was found that the quality of the LMX relationship had a positive effect on job satisfaction and reduced job stress, thus positively affecting job satisfaction. Job engagement was found to mediate the relationship between LMX and job satisfaction. This study is meaningful in that the search for multidimensional psychological and contextual factors that lead to job performance and job demands of married female workers are conducted.
