Impact of Korea train express (KTX) on the regional economy in Korea has been studied by many researchers. Current research is limited in the lack of quantitative research using a statistical model to study the effect of KTX on regional economy. This paper analyses the influence of KTX to the household final consumption expenditure, which is one of important regional economic index, using spatial panel regression model. The spatial structure is introduced through spatial autocorrelation matrix using adjacency of KTX connection. The result shows a significant effect of Korea train express on the regional economy.

Recently, with the development of ICT technology and the rapid spread of smart devices, a huge amount of information is being generated. The recommendation system has helped the informant to judge the information from the information overload, and it has become a solution for the information provider to increase the profit of the company and the publicity effect of the company. Recommendation systems can be implemented in various approaches, but social information is presented as a way to improve performance. However, no research has been done to utilize trust cluster information among users in the recommendation system. In this paper, we propose a method to improve the performance of the recommendation system by using the influence between the intra-cluster objects and the information between the trustor-trustee in the cluster generated in the online review. Experiments using the proposed method and real data have confirmed that the prediction accuracy is improved than the existing methods.

This study examined the moderating effects of gender on the influences of parental parenting attitudes on peer attachment in early adolescents. Data analysis was conducted over 1,912 respondents who met the purpose of this study among Korean Youth Panel KCYPS 7th year data of 1st grade in elementary school. The research methods examined the influence of variables on dependent variable, with difference of gender influences. As a result, it was found that gender, the control variable, and overall grade satisfaction affected peer attachment. Second, positive and negative parenting attitudes have confirmed positive and negative effects on peer attachment. Third, moderating effect was confirmed as parenting attitudes by gender show the difference of impact on peer attachment. Therefore, this study suggest to apply it to practical and theoretical implications and basic data for the program development to improve youth peer relations.

This study is to investigate the effect of lower extremity strength exercise using biofeedback system on community-based elderly. Ten community-based elderly were exercised using the biofeedback system (with functional electrical stimulation) three times a week for six weeks. Data analysis was performed using Wilcoxon signed rank test. Physical function improved significantly, but there was no significant difference in muscle strength and muscle mass. Although elderly people were able to confirm that community-based ICT home biofeedback training could be possible and could lead to improvements in the lower extremity function, further research is needed to demonstrate a clearer effect by expanding the target population, distinguishing the sexes, and providing a personalized training method.

ebXML(Electronic Business using extensible Markup Language) is an XML based new international standard framework of the electronic business. Interoperability among mutually different industry fields can be realized by reusing core component, as a infrastructure of data. For this interoperability, it is needed to define the concrete concept of core component, through analyzing the role and applicability of the core component in business process which defines the interoperability among different companies. Therefore, in this paper, we Inquire the role of the core component in the ebXML, and implement the core component storage system which generates core component to register in registry/repository. The designed system for storing the core component generates suitable core component structure to register in registry/repositor), which can be used to generate new business information entity in a modeling step of business process.

This study attempts to diagnose the trend of operation of small libraries and suggest direction for promoting them through a fact-finding survey on small libraries. According to the study results, it was important to make efforts for improvement such as reflecting the trend of increasing number of small public libraries and apartment libraries of small private libraries, enhancing substantiality of small libraries, human resource allocation for enhancing professionalism of running libraries, introducing activation measures that can consider the current operation situation of public and private libraries, establishing cooperative system between public and small libraries and enhancing accuracy of statistics data. As for the ways of promoting small libraries, change of direction toward qualitative operation support rather than quantitative increase, attempts to stabilizing operation of public small libraries, enhancement of specialty of private small libraries and establishment of cooperative system, strengthening of legal standard for small library and induction of corporate participation through campaigns were suggested.

The purpose of this study was to analyse the relationship between the characteristics of the patients who received oral antihyperglycemic drugs and their medical adherence in Korea. The study method was a cross-sectional study using the patient sample data of the Health Insurance Review and Assessment Service for 2016, and it was analyzed with 109 major components of diabetes drug. The medical adherence was slightly higher in male than female. The patriots & veterans(free) type had the highest medication adherence because they have low self burden to access medical institutions compared to other insurance types. It is expect that this study result will be used as a basic data to understand the burden of outpatients with health insurance and establish a policy to reduce of the self outpatients' burden with chronic diseases such as type 2 diabetes.

The purpose of this study was to analyze the effects of the daily life stress of the multicultural parents on the learning care style of the child and the mediating effect of the parent efficacy on the process. To this end, we surveyed 960 multicultural parents who responded to MAPS' multicultural youth panel 5th year data for parents. The main results are as follows. First, the daily life stress of multicultural parents did not affect the learning care style of their children. Second, parental efficacy was found to be mediating between daily life stress of multicultural parents and child's learning care style. In other words, the positive role of parental efficacy plays an important role in the child's learning care style by improving the stress-relieving ability of multicultural parents.

Today, Internet covers a world wide range and most appliances of our life are linked to network from enterprise server to household electric appliance. Therefore, the importances of administrable framework that can grasp network state by real-time is increasing day by day. Our objective in this paper is to describe a network weather report framework that monitors network traffic and performance state to report a network situation including traffic status in real-time. We also describe a mobile agent architecture that collects state information in each network segment. The framework could inform a network manager of the network situation. Through the framework. network manager accumulates network data and increases network operating efficiency.

It is noteworthy that EIS Consulting Method by ISP based on ERP Linkage Type for Large Scale Enterprise Associate Company. In this thesis, IT Strategy plan and methodology are suggested in order to solve the several problems including standardization on implementation of EIS Introduction and operation between large-small enterprise. Integration of business and information technical is made by Business management group's continuous IT concern and future information strategy. Also this paper proposes ISP Planning method (environment analysis, present analysis, IT analysis, target IT plan etc..), EIS Construction (based ERP Real data/time). In addition to, we suggest to use electron industry model and LCD/LED field in this system.
