As a strategy for strengthening local competitiveness, efficient use of regional assets is becoming more and more important. The key to regional identity and competitiveness is local assets. The purpose of this study is to derive the priority region for development by evaluating local assets. The analysis methods used in this study are Geographic Information System analysis, Big Data Trend analysis, and Analytic Hierarchy Process analysis. To assess the potential of local assets, the preference of assets, historical value, cluster of resources, wide-area transport accessibility, and population density were set as analysis indicators and itemized weights were applied using AHP to reflect the importance of each item. As a result of analyzing Yeongju city in Gyeongsangbuk-do, eight major points such as Buseoksa Temple, Sosu Seowon, Huibangsa Temple, Punggi Hot Spring Resort, Punggi Station, National Center for Forest Therapy, Yeongju east region and Museom Village were derived.

With the social infrastructure being deteriorated, there is a growing need to introduce the asset management to social infrastructure management in order to increase their value and save budget. Social infrastructure asset management is a new concept of facility management in response to these demands. It is defined as a procedure for collecting and analysing facility maintenance data and for making and practicing an economically optimized management plan. Detailed survey work of asset management business is analyzed in order to derive a strategy for asset management information. The contents of IIMM of New Zealand and the asset management definition of the FHWA of the United States, and representative facility management systems of Korea are analysed. The role between organizations and the relationship between business and organization were analyzed. Information required for asset management and for existing facility management systems is compared with business of asset management. In this thesis, three development strategies are suggested. The first one is to develop core business of asset management while excluding duplicated development. The second one is to divide system's structure into three layers. And the last one is to share information by interfacing asset management systems with existing facility management systems.

It is only 2 ~ 3 years in the interior to be introduced as a Ubiquitous era after going through mainframe, PC and internet era on account of the advent of computer. This thesis intends to present a model device of an epoch-making cash management system using the RFID(Radio Frequency Identification) Tag and EPC (Electronic Product Code) Platform which are core technologies of the Ubiquitous Computing on the assumption that cable and wireless internet is constructed in university. Also this sets up a purpose to minimize the administrative procedure as well as the waste of time, people and cost which are problems of the cash management system operating now. Therefore as a research project hereafter, it will be able to present an imporvement device about the problems which cannot solve these days through the model of the proposing cash management system when the standardization, normalization and commercialization of advanced IT department are accomplished.

In the latest intelligent computing environments, the self-adaptive software, as new software paradigm, which modifies its own behavior in response to changes in its operating environment is needed. To develop the self-adaptive software, it is necessary to analyze and design the context of software as well as the structure and the behavior of software. We need more efforts for self-adaptive software development than for traditional software development because we need more activities and technologies like context modeling and adaptation to develop the self-adaptive software. In this paper, we present the product line architecture for self-adaptive software and templates of artifacts to improve the efficiency of development through a reuse methodology. The artifacts of the architecture support the systematic reuse activities of core assets by expressing the commonality and variability of product line.

Product Line Engineering (PLE) has been widely accepted as a representative software reuse methodology by using core assets. As a key element of core assets, product line architecture (PLA) should be generic to a set of applications in the product line (PL). However, the difference between PLA and single system architecture has not been treated well enough, so evaluating PLA still remains as one of the difficult tasks in PLE. In this paper, we identify two intrinsic but overlooked issues in PLA; variability propagation chain and conflicts between architectural elements. And, we present a metric-based methodto evaluate PLA from the perspective of the two issues. We believe that the two issues in PLA and the evaluation method would make designing high-quality PLA more feasible and effective.

Software Product Line Engineering is a collection of techniques that analyze the commonalities and variabilities of the products within a product family and produce products using such information. In Software Product Line Engineering, construction of the correct core assets is very important. To accomplish this, the commonalities and variabilities must first be definitively identified, both to provide traceability between the core assets, and to guarantee the reliability of the products. This paper suggests software product line development and test processes based on CVL for the differentiation of commonalities and variabilities. The proposed approach enables correct building of the core assets through procedures to keep traceability and guarantee the reliability of the products.

국내 전력설비는 70년대 이후 제3차 경제개발 5개년 계획에 따라 중화학공업의 발전과 함께 급속히 성장해왔다. 과거 개발 위주의 산업구조에서 급속히 팽창한 전력설비는 21세기에 들어서면서 30~40년 장기 사용에 따른 노후화가 진행되었고, 증가하는 전력수요에 대응하기 위한 발전 및 송전 용지 확보의 어려움으로 인하여 전력설비의 신규 증설에 많은 어려움을 격고 있는 실정이다. 따라서 전력설비의 안전성과 신뢰성을 확보하기 위해 적절한 교체시기 선정 및 최적의 자산관리 필요성에 대해서 최근 관심을 가지기 시작하였고, 이러한 전력설비의 최적 자산관리에 핵심적인 전력설비의 상태평가 기술의 발달로 과거 시간기준의 유지보수(Time Based Maintenance)에서 최근 노후설비의 증가와 진단기술의 발달에 따른 예방보전(Preventive Maintenance)에 의한 상태기준 유지보수(Condition Based Maintenance)개념으로 전환되고 있다. 고전압 회전기기(발전기, 전동기)의 상태평가를 위한 핵심기술인 Off-line 부분방전시험이 널리 적용되고 있으며, 본 논문에서는 부분방전 측정 시험 시 대상설비 단자부의 인출케이블에 의한 감도저하 현상에 대해 고찰 하였다.

Product line analysis is an activity for analyzing requirements, their relationships, and constraints in a product line before engineering product line assets (e.g., architectures and components). A feature-oriented commonality and variability analysis (called feature modeling) has been considered an essential part of product line analysis. Commonality and variability analysis, although critical, is not sufficient to develop reusable and adaptable product line assets. Dependencies among features and feature binding time also have significant influences on the design of product line assets. In this paper. we propose a feature-oriented product line analysis model that extends the existing feature model in terms of three aspects (i.e., feature commonality and variability, feature dependency, and feature binding time). To validate the consistency among the three aspects we formally define the feature-oriented product line analysis model and provide rules for checking consistency.
