우리나라에서 대도시지역은 인구가 집중되고 있는 반면에 농촌지역은 인구의 감소현상으로 국토공간의 불균등 현상이 심화되고 있다. 따라서 농촌지역의 중소도시 역시 정체내지는 쇠퇴하여 도시의 계층, 중심지기능, 상품의 구매행위 등 지역의 중심지체계와 생활권의 변화를 겪고 있다. 더욱이 고속교통기관의 신설, 신공업도시의 접근, 공업단지의 입지 등은 지역도시의 중심성과 그 배후지역의 체계를 크게 왜곡시키고 있다. 본 연구는 경주시지역(구 경주시와 월성군)에 대한 중심지계층과 생활권의 현상과 변화에 대한 구명이다. 경주시지역은 최대중심지 경주시가 관광도시이기는 하나 그외 지역은 순수한 농업지역의 중심지들로 구성되어 있다. 그러나 최근 경부고속도로와 승용차의 보급으로 해안지역의 외래 관광객의 급증, 인접하는 공업도시 포항과 울산의 급성장 등으로 경주시지역 중심지체계에 많은 변화가 예상된다. 이와같이 급변하는 농촌지역의 중심지계층과 그 생활권의 연구는 학문적으로나 실용적으로 매우 의미 있는 연구이다.

PURPOSES : Owing to the growth of income and socio-economic levels, demands from road users have diversified. Accordingly, new road policies are being actively sought. The metropolitan city government of Busan has been focused on constructing and expanding roads to accommodate the increasing traffic demand. Given the increase in functional characteristics, we need to re-evaluate the hierarchy and function of roads, and specifically remodel the road planning and operations that fit into their functions. METHODS : First, this study focuses on introducing the minimum condition required to redefine the hierarchy of the roads. Second, the authors propose a new model that identifies the impact level of road hierarchy adopting discriminated analysis technique. RESULTS : Authors suggest that we redefine the hierarchy of roads in the central business distinct in Busan, and specifically the arterial roads in Busan, namely, Joonang-daero and Gaya-ro. These roads need to be reequipped with cross walks, a lower speed limit, and exclusive bus lanes to improve their accessibility. CONCLUSIONS : The authors found that the sub-arterial and collector roads have been subjected to excessive loads, owing to inappropriate functions being assigned to the main arterial road. Moreover, given that through traffic is concentrated on the sub-arterial and collector roads, over-speeding and other safety issues are consequently created.

Port Authority in Korea does not have financial independence nor fair recruitment practices, thus the prospects of the establishment of the Port Authority is not adequate. Therefore independent and effective port administration cannot be achieved. To overcome this situation, this paper examines the port administration system in Korea and identifies its problems. This paper then provides an 'modeling of Analytical Hierarchy structure' for evaluation. An alternative solution is provided by carrying out a public survey, analysing the significance of the evaluation factor using the techniques of the Analytical Hierarchy Process. The significance of profitability was identified. The role of central government is significant when assessing the public service function of port administration; and the role of the private company is significant when assessing the independence. In addition, the private company is significant when assessing profitability. The private company is the alternative for port administration in Korea, based on the evaluation of various alternatives.

This study aims to develop the living SOC function index and classified classes using the GIS-based spatial analysis method by applying the "Central Place Theory" as basic data for classifying living areas necessary for establishing rural spatial strategies in Boryeong. Boryeong-si is classified as a southern living area in the northern living area, centering on Daecheon-dong, the first class, and it is analyzed that living services such as used car service procurement and education are needed, and the southern living area needs a mid- and high-vehicle service delivery system in Ungcheon-eup. It is believed that this study can provide important clues to the classification of central functional facilities suitable for rural centers, reinforcement of vulnerable functional facilities by living area, and provision of living services.

The quality of performance evaluation on engineering consultants that provide design-related technical services is difficult to be measured, and only a handful of papers discussed the quality during the design stage. Although design cost is relatively far less than construction cost for a project, the decisions made in the design phase have a significant impact on the final products of the project, especially for large public construction projects. Therefore, this research focuses on reviewing and then establishing a performance evaluation framework for the consulting firms that execute detailed design and provide technical services for the Taipei Rapid Transit Systems (TRTS). By interviewing experts, this study first established a set of indicators to evaluate these firms' performance. Then, those indicators were incorporated into the four aspects of balanced scorecard (BSC) to establish the architecture of the evaluation mechanism. The weight of each indicator was calculated by analytic hierarchy process (AHP) from a survey conducted among experts. The results showed that the top-three indicators were quantity take-off, functions conformity, and budgeting. The framework of performance evaluation established by this study can be applied to measure service performance during the design stage. It not only facilitates the monitoring of consulting firms, but also helps to reduce unnecessary change orders and disputes during the construction stage.

Purpose - In order for actively pursuing medium and long term policies of Gangwon region to be effectively and efficiently driven, efficacious and practical development strategies are needed. In terms of regional revitalization in most regions that are dependent on the primary industry like Gangwon-do Province, the maintaining of local community becomes difficult and there are limitations on the support from the central government and local governments. Therefore, local communities need to implement measures not only to be financially independent but also maintain and activate themselves. And community business can be adopted to be a proper strategy to cope with this change. This study drew importance of a community business model appropriate for Gangwon-do region to figure out success factors. Research design, data, and methodology - This study aimed to come up with importance of community business model for Gangwon-do region by using AHP Method. AHP Method, which was developed by Professor Saaty in 1970', is a methodology to simplify complex problems for a rational decision making. A survey targeting related public officials and expert group was carried out and a total of 30 questionnaires were collected for the analysis. Results - Analysis model used in this study was to prioritize community business models of Gangwon-do region. The second hierarchy was divided according to local restoration type, local resource utilization type, environment improvement type, and life support type. The third hierarchy consisted of 5 items such as network, the middle structure, program, government support, and human resources to measure each importance. As a result, in the second hierarchy, local resource utilization type had the highest importance. In the third hierarchy, the middle structure had the highest importance, followed by government support, program, network, and human resources. Collectively, the results suggested that important critical factors of community business model of Gangwon-do region was the importance of local resource utilization model and the middle structure. Conclusions - Not only should projects that are already operating in the region but next community business projects that are planning in the Gangwon-do region should be practically operated in view of the importance and the models derived from this study.

병원, 행정기관, 은행과 같은 조직체의 경우 중요하고 민감한 데이터를 보호하기 위해 데이터베이스 보안이 필수적이다. 최근 대규모의 조직체에서 업무가 더욱 다양하고 복잡해짐에 따라 보안 정책에 대한 변경이 빈번히 일어나게 되었다. 따라서 보안정책의 무결성을 보존하면서 변경이 용이한 유동적인 보안 정책과 효율적인 보안 관리가 매우 중요하다. 본 연구에서는 의료정보관리시스템을 대상으로 Improved Role Hierarchy(IRH)를 이용한 유연성 있는 데이터베이스 보안 시스템을 구현하였다. 데이터 접근은 MAC 방식으로 제어하며, RBAC의 역할 계층(Role Hierarchy)을 개선한 IRH를 사용하여 유연성 있는 접근제어를 제공하고 효과적인 보안 관리를 할 수 있다. 본 시스템은 보안정책이 바뀔 경우 분산된 보안관리 방식으로 IRH를 수정함으로써 정책 변경을 용이하게 하며, 주체의 보안등급이 고정되어 있지 않은 상태에서 이를 IRH을 통해 사용자와 세션이 맺어질 때 결정되게 함으로써 정책이 바뀐 후에도 변경된 보안정책을 유연하게 적용할 수 있다.
