  • The purpose of this paper is to analyze the implementation of the GIS infrastructure systems for the u-City, GIS base u-City represents spatial information derived fields, such as geographical distribution of the urban boundaries, physical configuration of the urban locations and cultural characteristics of the urban history. These three aspects relate to urban infrastructure systems implementation, urban monitoring center implementation, and spatial database implementation. In terms of the GIS based u-Ci쇼 urban infrastructure implementation systems, the u-City depends on IT contents and spatial features. IT contents are strongly related to IT839 strategy due to the national agenda is "u-Korea". GIS should contribute to u-City construction through the spatial analyses methods. For these methods various GIS functions will guide to u-City's distribution, location, and characteristics of urbanization. The infrastructure consists of road and road facilities, underground facilities, related agencies facilities, dispatch systems, environmental systems, and urban planning. These six units of the urban infrastructures have spatial databases that consist of spatial configuration, such as dots, lines, and polygons in order to draw the spatial distribution of the u-City GIS based u-City urban infrastructure implementation systems should deal with It convergence to generate fusion affects.

  • Living infrastructure facilities are concentrated in cities with high population density, it is necessary to supply basic living infrastructure facilities to promote welfare in rural areas. The establishment of basic living infrastructure is the minimum right for daily living of local residents. It is supplied by considering national economic and social characteristics through national minimum standards, but it is limited to be practically applied to rural areas where many villages are dispersed in large areas. There is a situation. Therefore, it is necessary to supply systematic and quantitative facilities by analyzing villages that do not meet the minimum standards of basic living infrastructure in rural areas and by considering their characteristics. The purpose of this study is to identify the basic living infrastructure facilities of village units and analyze the characteristics of each village for Boeun-gun, Chungcheongbuk-do.

  • In this study, water resource topics, infrastructure, water supply, users, and economic indicators based on statistical annual standards for evaluating water welfare were selected by examining domestic and foreign water resource-related indicators. The level of water welfare was evaluated relative to 23 cities and counties in Daegu and Gyeongsangbuk-do using data from the Statistical yearbook, and places with high value of indicators urbanization and large populations were excellent in the infrastructure field, but overall analysis showed that small and medium-sized cities had higher levels. It is judged that it is necessary to develop continuous research and indicators that can evaluate and quantify the level of physical welfare that the people can feel by utilizing the results of this study. In future studies, it is necessary to systematically evaluate the level of water welfare by local governments in Korea through more diverse evaluation items and detailed indicators for each item so that it can be used as basic data for realizing water welfare.

  • The purpose of this study is to develop and validate a model of firm's IT capability based on IT resources such as IT infrastructure, IT personnel, and IT routine. To do this, the study defined IT capability as a third-order factor model and identified three conceptual dimensions of IT capability: IT infrastructure flexibility, IT personnel expertise, IT resource management capability, IT resource management capability indicates a capacity generated by IT routines, a new IT resource type identified in this study. The validity of the proposed model is evaluated with 243 firm level data using LISREL. The results of confirmatory factor analysis(CFA) demonstrated that the model is highly reliable and valid. Additionally, it was found that IT routines have a high potential as a new IT resource category.

  • 초고속 네트워크의 보편화와 하드웨어 및 서버 기술의 발달로 인해 대규모 고성능 분산 네트워크 중심의 IT 기반구조 구축이 사회 전반에 걸쳐 확대되고 있다. 이러한 IT 기반 구조에 대한 평가 척도는 매우 다양하게 제시될 수 있지만, 기반 구조라는 특성 상 생존성 평가는 매우 중요한 척도로 간주된다. 주어진 IT 기반 구조에 대하여 어느 정도의 생존성을 가지고 있는지 평가하는 것은, 무수한 IT 기반 구조들에 대한 보편적인 평가 척도를 제시하는 것일 뿐만 아니라 해당 평가결과를 토대로 한 추가 개선 작업을 통하여 더욱 생존성이 강화된 IT 기반 구조로의 발전을 보장해준다. 본 논문에서는 현재의 IT 기반 구조를 구성하고 있는 개별 구성요소들에 대하여 이미 구축해 놓은 방어메커니즘 데이타베이스(DMKB)를 토대로 하여, 전체 IT 기반 구조의 생존성을 평가하는 시스템을 제시한다.

  • The perception of earthquake in Korea has changed due to the earthquake that occurred in Gyeongju and Pohang, and the earthquake has become an important factor in infrastructure management. Damage to infrastructures in the event of an earthquake is extensive. In particular, damage to infrastructures that perform public function used to spread to the whole area. From the point of view of earthquake disaster prevention, it is very important for the public to define what infrastructures are important management targets and to prepare a countermeasure. In this study, we propose a method to evaluate the importance of infrastructure to effectively manage infrastructures for earthquakes. For this purpose, important factors for the railway bridges, power generation and electric power facilities, and apartment complexes are suggested. AHP analysis is conducted to suggest priorities. In addition, the evaluation criteria for infrastructure importance are presented.

  • The bench of cut-slope is necessary to stabilizing. But it is possible to be a weak zone in slope. When a small scale failure is occurred in a bench, it influence a large scale failure of slope. So when it is found out any unstable factor, weathering of rock, a direction of joint in a bench, if the bench is reinforced suitably, the holly failure is prevented in cut-slope

  • There are some problems on the system that uses a password comprising a digital signature to identify the secret key owner under the public key infrastructure. For example, the password can be difficult to remember or easy to be disclosure, and users should make more complex password to protect it. A number of studies have been proceeded in order to overcome these defects using the fingerprint identification technologies, but they need to change the current standard of public key infrastructure. On the suggested private key escrow system, the private key can be withdrawn only through the enrollment and identification of a fingerprint template after it is saved to a reliable third system. Therefore, this new private key escrow system can remove previous inconveniences of managingthe private key on current public key infrastructure, and it exhibited superior results in terms of the evaluation items when compared with the integrated method of the existing fingerprint identification and public key infrastructure.

  • The subject village of our study has numerous tourist attractions around it, and possesses various Confucian cultural heritages. The purpose of this study is to investigate public space improvements of a village possessing abundant historical and cultural heritages that has turned into a experience-tour village. As for the research method, cultural and social characteristics of the village were identified. In addition, infrastructures were classified by livelihood based infrastructure, tour based infrastructure, and agriculture based infrastructure in order to analyze individual public space improvement cases. As a result, it was found that public space improvements of the village improved the educational facilities and tour resources using historical resources. In addition, it was found that public spaces for residents to get along with tourists(who are willing to experience the village) were created.
