The restructuring of Korean railway industry, separation of between train operators and an infrastructure manager, had been conducted in 2004 to increase the productivities of railway operations. However, the maintenance-staffs are still employed by Korail (train operator), not by the infrastructure manager, which led the maintenance of railway infrastructure to be conducted by the train operator. The infrastructure manager is now only taking care of financial transferring issues once the train operator requests expenses spent for facility maintenance. Such incomplete restructure may result in a lack of safety performance on railway operations as the roles and responsibilities are less likely to be assigned under the multiple train operators. Thus, this study proposes the way of structuring maintenance divisions and their roles and responsibilities to assure the safe work execution under the circumstance of multiple train operators on the same rail network.

A sudden increase of old people's free urban railway transportation resulted from the acceleration of aging trend causes the chronic deficit. As continuous deficit caused by the free urban railway transportation of old people is expected, a fairness problem about the fare system of using public transportation is issued because only the urban railway provides free-rides to them, which is contrast to bus-riders paying full payments. Therefore, the study intends to draw an alternate to solve the problem of the free urban transportation uses by calculating an appropriate fare ratio between the two transportation modes, which is expected to alleviate the fairness issue between the urban railway and the bus.

With a purpose of investigating the current status of resource organization for infants and young children's resources, this study examined 8 municipal libraries in J city and suggested recommendations for improvements. To do that, interviews were conducted with 8 children's librarians and 25 users, who were parents visiting the libraries. All libraries examined were using KDC to classify young children's resources, but books were shelved by the alphabetic order of publishers' names. This arrangement strategy was regarded very convenient in re-shelving materials from the perspective of librarians, but users had difficulties in finding books because of the separation of the classification system and the arrangement system. Also, the online public cataloging system did not provide accurate and sufficient information to locate a book. Based on the results, this study suggested two ways for improvements: (1) classifying and arranging books by KDC, (2) developing a new classification system customized to infants and young children.

Market failure occurs when Pareto efficiency is not achieved through market mechanism. In order to solve this problem, government intervene market; paying great attention to the optimum state of resource allocation. However, as the size of government investment in R&D goes up, many professionals emphasize the importance in efficient management system. This work is the result of exploratory study to look into life-cycle management of governmental R&D program. Literature reviews and empirical research on governmental R&D programs elicit improvements for effective life-cycle management of governmental R&D program as follows: consistent discrimination between capital expenditure and recurring expenditure, dual management system by spending properties, implementing total cost management system in capital expenditure, and discrimination between preliminary feasibility study with confirming total program cost in recurring expenditure.

The purpose of the study was to examine the vocational educational system of Egypt, focusing on the effectiveness of the three consecutive cycle-based curriculum and integrated technical education clusters (ITECs) in order to suggest some implications for innovating the current vocational education system of Korea. The vocational education system of Egypt is similar to that of Korea, in terms of general education to go to university and vocational education to go to labor market. However, the Egyptian system is different from the system of Korea in light of the three consecutive cycle-based curriculum that links secondary vocational education, vocational education of college level, and advanced technical and vocational education. In addition, the Egyptian system has adopted the "cluster" approach which integrates technical secondary school, intermediate technical college, and advanced technical college around one physical area so as to promote vocational education in collaboration with regional industries and to guarantee education quality. In the last part, some potential implications were suggested for upgrading the quality of vocational education of Korea based upon the benchmark results of the Egyptian vocational education system and career development of students.

현재 우리나라의 측량체계는 크게 측지분야와 지적분야로 이원화되어 있으며 측지분야에서는 2001년도에 측량법을 개정하여 ITRF2000좌표계와 GRS80 타원체를 측량기준으로 사용하는 세계측지계를 도입하였다. 하지만 지적 분야에서는 국민의 재산권과 직접적으로 관련이 있는 필지의 경계와 면적의 변화 연구는 미미한 상태이다. 따라서 본 연구는 2010년 세계측지계 도입 후 지적분야에서 발생할 수 있는 필지별 면적 변동에 따른 사회적 혼란 여부를 판단하기 위하여 서울특별시 종로구 숭인등 숭인4구역주택재개발지구를 연구 대상지로 선정하여 세계측지계 전환에 지적 필지별 면적 변화를 분석하였다. 분석결과 연구대상지는 세계측지계와 지역측지계가 종선(X)축으로 305.87m. 종선(Y)축으로 70.87m 편차로 두 좌표계 간 북동방향으로 313.97m의 차이가 있고, 현행성과와 비교한 결과 종선(X) 방향으로는 평균 +4.0cm, 횡선(Y) 방향으로는 평균 -3.0cm의 차이가 나타났으며, 필지별 면적의 변동량은 $1.0m^2{\sim}3.0m^2$ 차이가 있지만 허용오차 범위 내에 있으므로 세계측지계 전환에는 문제점이 없는 것으로 판단된다. 하지만 본 연구의 결과는 그 대상범위가 한정되어 있고 기 검증된 지적기준점 성과를 사용한 결과이므로, 향후 보다 효율적인 세계측지계 전환과 도입을 위해서는 현 지적기준점체계의 정확한 세계좌표계 변환 성과를 기준으로 한 대단위의 필지별 면적 변동량 및 허용범위 분석과 같은 추가적인 연구가 조속히 이루어져야 할 것으로 판단된다.

Characteristics of Contactor's Defect Liability was too many discussed. But it's not clearly defined yet. Because recent Government Construction Projects are very complex and executed through long time, too many conflicts were appeared related to Contactor's Defect Liability. Therefore to analyse and to resolve the conflicts legal aspects of Contactor's Defect Liability stated in Civil Law and Government Contract Act was systematically compared. The result of this research is as follows : (1) Characteristic of Contactor's Defect must be regarded as a breach of Contract and be an incomplete contract implementation. (2) To decide the range of Damage, Characteristic of Defect must be regarded. (3) Contactor's Defect Liability must be effectual from the day of delivery. (4) Retainage must be added to secure the completion during the Contract Period and Defect Repairing Liability must be omitted in the Contract performance Security.

It has been widely believed that the ethnic relations in Honolulu and Hawai'i in the early twentieth century were little associated with racist ideology because the white race was minority in terms of the racial composition. In reality, however, the racial and ethnic issues have played a major role in forming the past and present relations among ethnic groups. This study shows that the white-supremacy ideology exerted a strong influence on minority groups in Honolulu throughout the immigration and settling-down process, as much as in the mainland U.S. Clear occupational stratification and residential segregation among the ethnic groups in Honolulu represented almost the same situation as in mainland cities. The social segregation and spatial propinquity of their residential neighborhoods facilitated the construction of dichotomized identity: "Local" versus "Haole". Such transformed identities were a product of on-going inter-ethnic negotiation process embedded in the non-white multi-ethnic neighborhoods.
