This study aims to present promotion strategies for regional industries by exploring the ways to build industrial cluster focusing on regional strategic industries of Gyeongsanbuk-do(province) which are related to innovation city, by taking Gyeongbuk innovation city as an example. This study presented the methods for linking with innovation cities that focus on regional strategic industries, along with the analysis on the linkage between regional industries and public organizations relocated to local regions. As to the methods for the linkage, methods to build clusters based on the characteristics of each industry, such as electronic information device, new material parts, biological oriental medicine, cultural tourism, eco-friendly energy, etc, which are strategic and leading industries of Gyeongsanbuk-do(province), were presented. It was inferred that the industries which have achieved fast growth such as IT and BT industries, required mutually interconnected collaboration through geographical proximity among related subjects, while sectors with mature technologies, such as automative parts, machinery, steel industries, etc, were found to require more extensive infrastructures like the support of transportation and distribution for promoting current clusters.

Keeping the balance between exploration of new possibilities and exploitation of existing certainties in organizational innovation is getting its significance as business environments become more turbulent This paper focused on the relationship between two different types of innovation and network configuration. For this purpose, we conducted the empirical studies of 168 IT SMEs located in Gyeongbuk. For this analysis, we defined two innovation types as exploratory innovation and exploitative innovation. Also, we considered network scope and strength of tie as network configuration. The results showed that the exploratory innovation had sparse network of network scope and weak tie of strength. On the contrary the exploitative innovation had dense network and strong tie.

최근 고해상도 위성영상정보의 민간 사용이 활발해지면서 기존에 널리 알려진 위성영상정보 응용분야 뿐만 아니라 새로운 응용 분야에 대한 적용 가능성이 국제적으로 여러 가지 방향으로 모색되고 있다. 본 연구는 이러한 추세를 반영하여 교통 또는 도시교통 환경분야에서의 위성영상정보의 활용 가능성 및 기존 방법론과의 연계를 분석하고, 시험적으로 프로토타입 프로그램을 소개하고자 한다. 일반적으로 교통문제에서의 접근성 분석은 일종의 중력모델로 설명이 가능하며, 교통계획 수립시에 대안 도로 계획선정이나 대중교통 노선결정시에 많이 이용되고 있다. 접근성 분석에 대한 개념은 비교적 간단하여, 교통분석대상구역의 임의 지역에서 유인 요인과 거리를 변수로 하여 적용 목적에 부합되는 대상 지점까지의 정량적 지수정보를 얻도록 하여 몇 가지 결과로부터 출발지점에서 목적지점 또는 대상 지점까지의 손익비용산출에 대한 정보를 얻는 방식이다. 최근에 GIS를 통하여 구축된 교통 데이터베이스정보와 공간분석 기법을 통하여 수행하는 경우가 많으나 현재까지 위성영상정보가 이용된 경우는 거의 보고된 바가 없다. 따라서 본 연구에서는 정사위성 실제 교통시설물이나 교통 대상 객체의 육안 식별이 가능한 고 해상도 위성영상정보는 이러한 출발지-목적지 선정에 적용될 수 있다는 점에 착안하여 기존에 교통분야에서 개발된 몇 가지의 교통 접근성 산출 알고리듬에 위성영상정보가 연계되어 적용될 수 있는 가능성을 검토하였다.

This study is to integrate and to analyzegraphic and attribute data in features which should be preceding for the ITS construction. A 1:5000 scale map as a national basemap was used and was checked for feasibility. For the convenience of position confirmation, the analysis component was developed and was linked to addresses. Also, the attribute information was considered on the shortest route, and optimal route was selected by investigating traffic volumes on main crossroads depending on the time zone. The optimal route could be selected by analyzing user's demands, position and statistical data, and the position information could be provided efficiently by combining the graphic information with the land register information.

In Korea where there is the national curriculum and teachers depend highly on textbooks, the school mathematics is based on curriculum and textbooks. Especially considering responsibility that textbooks should reflect the curriculum properly, it is necessary to analyze the connection of mathematics curriculum and textbooks in order to review and improve the quality of our mathematics education. This research analyzes the connection of curriculum and textbooks for 5~6 grades and aims to have some implications for revision of the textbooks when application of elementary mathematics textbooks based on the 2009 revised national curriculum is completed to all grades. Following the preceding research for 1~2 and 3~4 grades, this research sets 5~6 grades as a subject of analysis and has four contents of analysis; analysis of textbooks based on restructured achievement criteria, analysis of connections between unit objectives of textbooks and the reconstructed achievement criteria, analysis of textbooks related to mathematical terms and symbols, and analysis of textbooks related to mathematical process. The result of analysis has some implications to develop textbooks based on the 2015 revised national curriculum.

We examine the effect of controlling shareholders ownership structure and related-party transactions(hereafter 'RPT') of publicly traded companies on their firm values during the post-IMF period. In the multivariate regression analysis using control variables such as firm size, capital structure, investment, dividend, profitability and industry dummy that might affect firm values, we find that there exists a significant negative relation between the controlling shareholders ownership structure and firm values proxied by Tobin's Q, and also find that there is a significant negative relation between RPT and the firm values. Those evidences seem to support the controlling shareholders' expropriation hypothesis. Additionally, we investigate the relation between ownership structure and rim value through the piecewise regression analysis. We find a significant 'inverse' U-shape pattern between the controlling shareholders ownership structure and firm values. This result is quite different from the existing literatures that have usually reported an U-shape pattern. In conclusion, the findings in this study do not support the notion that the ownership concentration to the controlling shareholders does negatively affect the firm values monotonically.

There is a growing interest in Co-operative education as an important way of university-industry collaborations for improving employment competitiveness, recruiting talented human resource, and promoting university-industry collaborations. In this study, we recognize that the paradigm of professional practice have to be changed from internship to Co-operative education. This paper examines the characteristics of Co-operative education in a regional public university through a case study of Central Washington University(CWU), USA. The results of the study and policy implications are as follows. First, the professional practice program of CWU is centered upon Co-operative education and has a high local and regional connectivity in terms of location of institutions that students work for professional practices. Second, the professional practice program of CWU has a high connectivity between majors and jobs, and is characterized by an active participation of students majoring in humanities, social sciences, arts and education. Third, the qualifications of Co-operative education are strict, but programs of Co-operative education are flexibly operated according to the characteristics of departments and colleges. We emphasize that universities in Korea need to focus upon the employment connectivity, the major connectivity, the local and regional connectivity, Therefore, when attempting to introduce Co-operative education. In addition, the management and governance of Co-operative education should be flexible.

The overall structural framework was studied using the regional 2D seismic data, followed by the sequence stratigraphic study on the 3D seismic and well- log data in the margin of the South Con Son basin of the South China Sea. This research contributes to delineate depositional stratigraphy, depositional environment and geologic history in the 3D seismic area of highly complicated faulting. Eight Miocene sequences were indicated on the 3D seismic and well-log data, in which the structural maps of each sequence boundary and the isochron maps for the corresponding sequence were made. The seismic facies were analyzed for each sequence volume and sequence boundary surface. The 3D seismic area is characterized by coal beds deposited in the transgression environment (transgression systems tract) and channel distributions just above the sequence boundaries. During the Early Miocene, the coals and thick shales deposited in the mangrove swamp representing the lower coastal plain environment. During the Mid to Late Miocene, thick clastic sediments deposited in the coastal to shallow shelf by regional subsidence and marine transgression. The isochron maps and structural patterns indicate that the sediments were transported from west to east or from northwest to southeast.
