통합 운영의 중요성이 대두되고 있으나 기존 교육 정보 시스템은 표준화 기반으로 개발되지 못하고 있다. 이로 인해 교육적 Asset의 필요성과 재사용 가능한 교육 서비스의 확보가 시급한 실정이다. 이미 개발된 컨텐츠의 활용도를 높이기 위해 특히 국제적 표준인 Sharable Content Object Reference Model(SCORM)을 기반으로 컨텐츠를 관리하고, 교육용 어플리케이션 개발도 재사용이 가능한 Asset을 이용하여 조립, 생산할 수 있는 방안이 필요하다. 본 논문에서는 체계적인 교육자원을 개발하고 지원하기 위한 교수-학습지원 시스템 개발에 초점을 두었다. 교육적 도메인의 접근과 Model Driven Architecture(MDA) 개발 프로세스의 각 단계별 Asset을 통해 시스템을 개발한다. 또한, 학습 컨텐츠 메타 모델을 기반으로 컨텐츠 저장소에 관한 분석과 설계를 통하여 MDA 자동화 도구를 이용한 교수-학습지원 시스템을 개발하고자 한다. 이를 통해 교수자와 학습자가 필요로 하는 교육컨텐츠 재사용성을 높이고 전체 개발 프로세스의 Asset을 이용하여 교육용 응용소프트웨어 개발 기간의 단축과 개발비용의 절약 및 생산성을 높일 수 있다.

본 연구는 국내에서 시행중인 자산형성사업에 대한 이해를 높이기 위해 자산형성사업 참여자의 저축행위와 경제상황에 대한 인식, 사업에 대한 태도에 영향을 미치는 원인을 분석하였다. 이를 위해 서울시복지재단에서 자산형성사업인 희망플러스통장 사업 참여자를 대상으로 2009년부터 2011년까지 3개년도 동안 구축한 종단자료를 사용하였다. 또한 시간의 흐름에 따른 변화를 파악하기 위해 위계적 선형모형(HLM)을 이용해 분석하였다. 분석 결과 개인적 특성에서, 장애가구의 경우 비장애 가구에 비해 생활형편에 대한 인식이 부정적이고 월평균 저축액도 적은 것으로 나타나 특별한 관심이 요구되는 것으로 나타났다. 희망플러스 통장에 참여하여 시간이 지날수록 생활형편이나 경제상황에 대한 인식은 긍정적으로 변화했으나, 실제 희망플러스통장 저축액을 제외한 저축액은 증가하지 않았다. 반면 소득수준이 높을수록 월평균 저축액도 높아지는 것으로 나타나 소득과 저축액 간에 정적 상관관계를 발견할 수 있었다. 본 연구는 참여자의 저축행위와 경제상황에 대한 인식, 사업에 대한 태도에 영향을 미치는 인구 사회학적 변수들의 특성을 알아봄으로써 자산형성정책이 참여자의 어떠한 특성에 초점을 맞추어 설계되어야 하는지에 대한 함의를 얻을 수 있었다.

This study examines the effect of family resources on low-income families by exploring their holistic experience of poverty to the formation of resilience. A grounded theory approach is utilized to structure process from their experience of poverty as well as the use of social welfare services to the formation of resilience. This study targets 17 families involved in the pilot project for the beneficiaries of an asset building program in Seoul. In accordance with open coding and a paradigm model by the result of axial coding, 86 concepts, 23 sub-category, and nine categories are produced. These categories are classified into the causal condition (a tough life due to poverty), contextual condition (being the recipient of an asset building program), intervening conditions (interpersonal resources and effects of accumulated time or experience), central phenomenon (a will to live and overcome poverty), actions/interactions (active behavior and change of attitude), and consequences (change of asset levels and increased efficacy in their lives). The integrating categories identify the core category as 'the process of making a resilient life out of the power to live' and a final process model is organized. The results suggest crucial implications to develop comprehensive policies to address poverty issues for low-income families with a strength-based approach.

A CCTV inspection method has been widely used to assess sewer condition and performance, but Korea lacks a proper decision support system for prioritizing sewer repair and rehabilitation (R&R). The objective of this paper is to introduce the results that we have developed in the Sewer Condition Assessment and Rehabilitation Decision-making (SCARD) Program using MS-EXCEL. The SCARD-Program is based on a standardized defect score for sewer structural and hydraulic assessment. Priorities are ranked based on risk scores, which are calculated by multiplying the sewer severity scores by the environmental impacts. This program is composed of three parts, which are decision-making for sewer condition and performance assessment, decision-making for sewer R&R priority assessment, and decision-making for optimal budget allocation. The SCARD-Program is useful for decision-makers, as it enables them to assess the sewer condition and to prioritize sewer R&R within the limited annual budget. In the future, this program logic will applied to the GIS-based sewer asset management system in local governments.

Software product line is a software product or a set of software system, which has common functions. We can develop a specific software product, which satisfies requirements of a particular market segment and a mission in a specific domain by reusing the core asset such as the developed software architecture through the software product line. Software development methodology based on the software product line can develop a software more easily and fast by reusing the developed software core asset. Developed countries of software technology select software product line as a core field of software production technology, and support technology development. In case of USA, CMU/SEI(Carnegie Mellon University/Software Engineering Institute) developed product-line framework 4.0 together with the industry and the Department of Defense. Europe is supporting the development of product line technology through ITEA(IT for European Advancement) program. However, industries in our country understand the necessity of software production technology based on product line concept for the purpose of increasing productivity, it is not sufficient to invest for this technology development. In this paper, we aim to construct the common architecture of software product line for production of the software product line.

A competitive generating company (GENCO) could maximize its payoff by optimizing its generation assets. This paper considers the GENCO's arbitrage problem using price-based unit commitment (PBUC). The GENCO could consider arbitrage opportunities in purchases from qualifying facilities (QFs) as well as simultaneous trades with spots markets for energy, ancillary services, emission, and fuel. Given forecasted hourly market prices for each market, the GENCO's generating asset arbitrage problem is formulated as a mixed integer program (MIP) and solved by a branch-and-cut algorithm. A GENCO with 54 thermal and 12 combined-cycle units is considered for analyzing the proposed formulation. The proposed case studies illustrate the significance of simultaneous arbitrage by applying PBUC to multi-commodity markets.

This study aims to examine the family awareness and the demand for a group-based healthy family support program for current and former residents of a residential care institution, and to provide information to be utilized in the development of a comprehensive group-based family support program. To support this study, 1:1 interviews were conducted. The interviews focused on the adolescents' perception of their own families, perception of family in general, demand for a group-based healthy family support program, etc. The results of the interviews are as follows. First, as for the perception of their own families, the 'happiest' and 'saddest' experiences they reported were related to their own families for both the current and former resident adolescents of the institution. Second, as for the perception of family in general, both groups defined a healthy family as a family with members who 'help one another in times of difficulties and live happily in harmony together'. Third, regarding the educational contents that are essential to the establishment of a healthy family, a majority of the current residents answered cooking, yet a majority of former residents mentioned more practical education-such as the role of parents, child education, asset management, human relationships, and self worth enhancement, etc.
