The objective of this research is investigating the mediating effect of job engagement on the relationship between job autonomy and innovative behavior in public organizations. Major findings from Structural Equation Model analysis demonstrates that the variable 'job engagement' took a positive role between job autonomy and innovative behavior. From theoretical point, this result provides the empirical evidence of causal relationship in the three components of attitude-cognition, emotion, and action, which contributes to the advancement of action theory. Some policy implications can be drawn from the empirical findings. Firstly, job autonomy need to be seriously considered as a strategic instrument for the encouragement of innovative behavior. Secondly, job engagement of employees need to be more carefully monitored to stimulate the innovative behavior in the public organizations. In public organizations, enhancement of innovative behavior can not be achieved from institutional arrangements. Provision of job autonomy is more effective method of behavior change than performance management approach.

Transition toward sustainablity being in progress in a variety of areas including climate, energy, household, transportation. This study analyzed system transition and backcasting of its management with case of sustainable transportation, foods, household system transition in the Netherlands. Backcasting has become a popular approach for sustainability taking a more reflexive perspective and looking back to the participatory experiments. In the Netherlands, participatory backcasting utilized as s innovative approach for long-term strategy for sustainability, based on stakeholder involvement, construction of normative sustainable futures, stakeholder leaning. In this study, we can be understood that transition management requires the participation and contribution of business, government, research and the public & public interest groups and backcating is tool leading to a sustainable future vision, stakeholder involvement. To create a new path toward sustainablity, it requires integrated consideration of related policy perspectives and participatory backcasting aiming at system innovations for influencing transitions.

This study has attempted to suggest an assistant model for systematic child care accreditation. This has been carried out from the current consciousness of such needs for child care accreditation as large regional disparity in assistant level, no indication to definite contents and method of assistance, demand for assistant professionals with intensified capacity and requirement for the support of financial and human resources. Six stages of assistant process: the stage of establishment and management of preparation class, the stage of application for assistance and consultation, the stage of assistant meeting, the stage of workshop and observation to exemplary institutions, and the stage of practical application and evaluation of visiting assistance have been suggested. Particularly in order to improve the efficiency of assistance, organization of a committee of expert advisors in each area has been indicated. For the guideline of assistant management, operation of preparation class for accreditation, security of assistant committee members, provision of systematic training and assistant manual, development of supervision program and financial support have been suggested. This assistant manual will contribute to systematic and efficient conduct of assistance program of child care accreditation.

Recently, there is has been significant interest in the allocation systems of rail track capacities with considerations of the multiple train operating companies. The system indicates both a well-defined procedure and an algorithmic method to allocate the rail track capacities. Among them, this study considers the algorithmic method to derive the optimal timetable for the trains, which the companies propose together with their arrival and departure times at each station. However, most studies have focused on the adjustment of the departure and arrival times without conflicts, which could result in incompatible allocations with the line plan, which would result in an insufficient number of trains on each line to satisfy the demands. Our study presents a new optimization model and algorithm for the allocation problem in order to reflect the predetermined line plan. Furthermore, we provide the experimental results that were applied to the Korean high-speed railway network including the Suseo lines.

This research was initiated on the basis that public libraries should serve its role as a supplier of intellectual informations to all users and the National Library of Korea should play a role as chief supporter of collection preservation in individual libraries. Situated in such context, this study attempted to investigate several aspects of the present conditions of Korea public libraries, including the current technical ability and technicians available for materials preservation and restoration, current policies for preservation and provisions for disasters, and opinions on establishment of national library preservation and restoration center. Data was drawn from a survey with 208 public libraries in the country. As a conclusion, this study discusses such as 1) securing collection management policies for material preservations and restorations at the level of individual libraries 2) building tripartite system for efficient and methodical material preservations and restorations including public libraries, regional central libraries and the National Library of Korea.

This article aims to explore the connectivity and centrality between environment law and spatial law, where make implications in environmental planning. To achieve it, we used Network Analysis(NA) as a tool for analyzing the connectivities. 52 environmental Laws and 29 Spatial Laws are selected and used for this analysis. This study also attempts to explain the phenomenon through quantitative study rather than qualitative research. This paper is methodologically the first attempt to Environmental Law study, which will help to understand the structure of complex Environmental Law. The result of the network analysis for connectivity between Spatial Law and Environmental Law demonstrates that two laws are in less mutual relationship with each other. It also supports that Environmental Law and Spatial Law need to be closely connected with each other for effective environmental management.

여행 정보 시스템(ATIS), 교통 관리 시스템 (ITS) 등 궤적 기반 서비스에서, 서비스 품질을 향상시키기 위해서는 주어진 궤적 질의에 대한 정확한 주행시간을 예측하는 것이 필수적이다. 이를 위한 대표적인 공간 데이터 분석 기법으로는 데이터 분류에서 높은 정확도를 보장하는 규칙 기반 분류화 기법이 존재한다. 그러나 기존 규칙 기반 분류화 기법은 단일 컴퓨터 환경만을 고려하기 때문에, 대용량 공간 데이터 처리에 적합하지 않은 문제점이 존재한다. 이를 해결하기 위해, 본 연구에서는 맵리듀스 환경에서 규칙 기반 분류화를 이용한 궤적 데이터 주행 시간 예측 알고리즘을 개발하고자 한다. 제안하는 알고리즘은 첫째, 맵리듀스를 이용하여 대용량 공간 데이터를 병렬적으로 분석함으로써, 활용도 높은 궤적 데이터 규칙을 생성한다. 이를 통해 대용량 공간 데이터 기반의 규칙 생성 시간을 감소시킨다. 둘째, 그리드 구조 기반의 지도 데이터 분할을 통해, 사용자 질의처리 시 탐색 성능을 향상시킨다. 즉, 주행 시간 예측을 위한 규칙 그룹을 탐색 시 질의를 포함하는 그리드 셀만을 탐색하기 때문에, 질의처리 성능이 향상된다. 마지막으로 맵리듀스 구조에 적합한 질의처리 알고리즘을 설계하여, 효율적인 병렬 질의처리를 지원한다. 이를 위해 맵 함수에서는 선정된 그리드 셀에 대해, 질의에 포함된 도로 구간에서의 주행 시간을 병렬적으로 측정한다. 아울러 리듀스 함수에서는 출발 시간 및 구간별 주행 시간을 바탕으로 맵 함수의 결과를 병합함으로써, 최종 결과를 생성한다. 이를 통해 공간 빅데이터 분석을 통한 주행 시간 예측 기법의 처리 시간 및 결과 정확도를 향상시킨다.

With the rapid and broad changes of information ecology human information activity is moving toward a new pattern-networking. Various types of information networks are being constructed over the world, and through the networks various forms and contents of information are being flowed or transferred. Under these circumstances a serious question could arise regarding whether the present cataloging principles and practices are right and appropriate for the so-called 'digital network generation of library users'. This study was developed to explore this question. Especially, this study conducted an analysis on the utility of library catalog with an emphasis on the perspectives of library users. As a result, it turned out that the quality of library catalogs produced by Korean universities was in a very low standard. The degree of satisfaction on the quality was very low, particularly among library users. In conclusion, this study made several suggestions on the cataloging policy and practices: both at the national level and the unit library level.

The purpose of this study is to observe whether the specialized quality programs of senior welfare centers actually help service users and meet their needs. In order to find out, we have utilized three different research methods. First, an in-depth interview was generated among the service users of senior welfare centers. Second, the specialized quality program in senior welfare centers was analyzed. Third, a focused group interview among the senior welfare experts was conducted. Based on the results of this study, they suggest four practical proposals. First is to enhancing programs of senior welfare centers based on the service users' rights. Second is to providing high-class services by developing and transforming the 'elderly culture.' Third is to converting the existing programs to make associations with their local communities. Last is to building a network as a hub to communicate and sharing outstanding programs within senior welfare centers.

Ryu Seongryong, a Confucian scholar and politician, are two sides of the same coin that cannot be separated from each other. The scholarship of Confucian intellectuals is oriented toward the practice of the managing state and salvation of the world(經國濟世), and the precise study of historical precedent and political scene affects the success or failure of politicians. Ryu was able to become a real savior of Joseon Dynasty in crisis, because he synthesized dialectically both without distinction between theory and field. However, previous studies on Ryu did not pay attention to these points. In this article, I would like to start from the point that Ryu was interested in the Learning of Wang Yangming without being satisfied with the Neo-Confucianism. And I want to emphasize that he had a pragmatic view that was different from the orthodox scholars and that he was able to demonstrate his ability to cope with crisis even when Joseon was hit by the Japanese invasion of 1592. In short, this article seeks to re-examine Ryu's life in terms of pragmatism and realism which pursued a balance between learning and practice.
