SK텔레콤은 급변하는 이동통신시장 환경의 변화에 적절히 대응하기 위하여 지난 10여 년간 사용해 온 메인프레임 기반의 COIS 시스템을 중단하고 Unix 기반의 NGM 시스템으로 다운사이징하기로 결정하였다. 2002 년 9 월 SK 텔레콤은 차세대 IT 인프라 혁신 전략 프로젝트를 완료하고 이에 근거하여 2003 년 말 1 단계 프로젝트를 추진하게 된다. 그러나 개발 툴의 문제점, Governance 의 확보 실패 등 문제점이 계속 누적되어 2005년에 접어들어서는 총체적 난국 상황에 봉착하게 되었다. 2005 년 2 월 자체 점검 결과 개발 진척도는 50%에 불과한 상황이었다. 결국 2005 년 3 월, NGM 추진본부는 프로젝트의 추진 중단을 선언하기에 이르렀다. NGM 프로젝트는 처음부터 재 검토하여 Re-planning 을 실시한 후 구축을 재개하기로 결정하였다. 2005 년 5 월 NGM 프로젝트의 Re-plan 이 수립되었다. 우선 Turn-key 방식의 문제점을 해소하기 위하여 SK 텔레콤이 구축의 총책임을 떠맡고, SK C&C 가 시스템 이행에 대한 책임을 지는 Governance 체제를 확립하였다. 또한 2 단계 프로젝트에서는 NGM 프로젝트를 기술적으로 원점부터 재 검토하여 이전과는 근본적으로 다른 In-House 구축 접근방식을 채택하기로 하였다. 2 단계 프로젝트에서 관심을 집중한 기술적 의사결정 영역은 크게 (1) 미들웨어 및 개발프레임워크의 적용, (2) DB 아키텍처의 결정 및 슬림화, (3) 시스템 성능 개선 등의 세 분야로 집약할 수 있다. 이 논문에서는 이들 각각의 분야를 구체적으로 검토하였다. 결국 2006 년 10 월 9 일 메인프레임 기반의 COIS 는 Shut-down 되어 가동을 멈추었고, Unix 기반의 NGM 시스템이 가동을 개시함으로써 차세대 마케팅을 본격 추진하기 위한 다운사이징 프로젝트가 성공적으로 완수되었다.

This paper presents an in-depth review for current status for demand-side management (DSM) investment of energy supplier and an useful prospect on the introduction of Energy Efficiency Resource Standards (EERS). According to the Article 9 of Rational Energy Utilization Act, Energy suppliers-Korea Electric Power Corporation (KEPCO), Korea Gas Corporation (KOGAS) and Korea District Heat Corporation (KDHC) prescribed by Presidential Decree-must establish and implement annual demand-side management investment plan to improve energy efficiency in production, transformation, transportation, storage and usage of corresponding energy and to reduce demand and green house gas emissions. In this paper, we examine the DSM programs of energy suppliers and the results of DSM investment in 2009, then we propose a reasonable solution for the development of DSM investment. Furthermore, in order to compare our situation, the case studies were conducted on EERS issues in England, Italy, France and U.S, such as establishing the energy saving target, selecting the target energy supplier, and penalty and incentive mechanisms. Throughout the case studies, this paper suggests the directions to the DSM investment planning of energy suppliers and the major issues to prepare EERS in Korea.

All Korean professional engineer′s great joy Is to welcome the Japanese professional engineers and relevant guests to the 1987 Japan-Korea Professional Engineers Joint Convention organized by the Korean Professional Engineers Association. As there exists an effort of blood, sweat and tear behind a succeeded theatrical stage, so an exquisite devotion with drawing up a master plan, investigation, supervision and etc by engineering firms is soaked through every part of huge construction projects and large unit factory buildings. It is over 14 years that the Engineering Service Promotion Law has been enacted by the Ministry of Science and Technology. In the meantime, the domestic engineering (engineering service) have reached a remarkable higher level while the number of engineering firms participating in overseas market has gradually been increasing. From a small scale of under water investigation to a large scale planning of atomic reactor or petrochemical plant, engineering service business can be said "The Software of Total Industry." Engineering service is what is called a higher business which offers specialized engineering know-how and experience. Engineering service compaines offer Its specialized knowledge and experience to government, industry and commerce. Whether the task is to modernize plant equipment, to design a building or to manage construction, an engineering company will develop and implement the most appropriate and cost effective solution. Clients use the engineering service of firm knowing that the engineer′s professional judgement is not influenced or biased by other commercial affiliations. While benefiting from the diverse experience that professional engineers can apply to a specific problem, government and industry also reduce the need for permanent in-house engineering staff. Engineering firms may be specialized or multi-disciplinary.

Today, as proved in many foreign developed countries, the concept of 'Aging in Place' is the most desirable goal of welfare policy for an aging society. While multi-family housing is the most representative form of residence in Korea, it has not actively reflected convenient space lay-out for the elderly and barrier-free designs. As a foundation for the planning of elderly-friendly multi-family housing, this study suggested the comparative analysis of the five domestic design guidelines for elderly housing so as to apply the elderly-friendly flexibility for apartment units. In result, the most importantly treated items and factors of the silver house guidelines were analyzed, and based on which ten unit houses of domestic apartment housing were evaluated in order to find out the most barrier-like spaces and factors for the present domestic apartment housing to reflect flexibility as elderly housing. Finally, the way to resolve the problem was suggested as a conclusion.

The funeral and grave system in Korea has issued that our country will become a grave. This is a result of being in favor of the funeral and grave process of burial based on long time traditions and customs. The government is allowing construction and use of charnels on a large scale in order to improve this system after analyzing the problems of the current grave system; However, those results are very few and slight because the image of existing charnels have been regarded as abomination utilities and it has been projected not to be closed to the public easily. In this stduy, we first looked at these problems using sample research and analysis. Second, we made comparisons and analysis to suggest solutions in the projecting method and feature of those spaces by carrying out a sample research project. This project was based on 3 of the biggest charnels built recently, which are out of the 54 charnels in Korea. After assaying the image according to the interior designing elements, and then proposing various several alternatives, we would like to tell how to build the future-oriented and opened charnels as the purpose of this study. Therefore, when projecting charnels, we would like to suggest the alternative solution that diminishes abomonation and closeness in the interior of the charnel through the designing consideration and increases the usage of this building by inducing traditional limitations and maintaining vertical dignity and piety by making the central axis adapting to the nature.

The purpose of this study was to set and analyze the feasibility and survey of the Hanok(The traditional Korean style house) housing complex project within Seoul metropolitan area. The results of this study were as follows. First of all, a survey was carried out to find out the optimum Hanok style. The survey showed that many people chose a frond and back yard garden as a merit of Hanok and pointed out the weak crime prevention as a weakness of Hanok. The optimum size for a Hanok was from $264m^2$ to $330m^2$ and living space was from $100m^2$ to $132m^2$. And people considered about 120% of what the apartment sells for as the reasonable price of a Hanok. Based on the survey, this study planned a Hanok housing complex on a lot that has competitive price and analysed the feasibility of the housing plan. The result was that Hanok's construction cost per $3.3m^2$ to be a marketable product has to be below about 6 million Won. As a result, the construction cost-saving through the advanced technology and planning to meet the changing customers' needs are needed to vitalize Hanok's supply.

The purpose of this study is to minimize physical obstacles, to propose how we can improve them, and to get the basic information to establish the welfare policy for handicapped students in the university dormitory by studying and analyzing actual conditions of existing facilities and its improving transition which provide most important living accommodation to university students. To carry out this study, they have been surveyed 10 Universities in Korea as a case study which 1 university in Seoul & Kyunggi province, 2 universities in Chungchung province, 5 universities in Jeolla province and 2 universities in Kyungsang province. And they have been studied in relation to the law, theory of the architectural planning & design, and general consideration about handicapped people. As a result the checklist about the facilities was made. The term of survey was in August 2001 and in September 2004. It is concluded that most of universities which have been surveyed were equipped with good facilities for general students without regards for handicapped people at that time. As you can see the result of this research, the facilities of boarding house for handicapped people are very scanty in many universities. So they must be required facilities for handicapped people in the stage of architectural programming, the process of designing the dormitory facility.
