As eco-friendly and sustainable architecture is becoming more popular, the interest in Korean traditional wooden buildings (Hanok) has also been increasing. The building technologies of the wooden construction have been actively developed in all over the world through the diversification of new materials and construction methods. On the other hand, the growth rate of wooden construction market is still slow in Korea. In an attempt to promote the Korean traditional wooden buildings, a comprehensive research project has been conducted. This R&D project is developing standard designs, new materials, and methods for modernized Hanok including houses, public buildings, long-span structures, and even high-rise buildings. To this end, the purpose of this study is to formulate a technological strategy for popularization of modernized Hanok. Influencing variables and issues are analyzed and defined first. At the same time, the five keywords have examined in the perspective of dissemination of modernized Hanok technology. Finally, a technology road map for strategic development of modernized Hanok is proposed through casual diagrams.

The populations of major cities in Australia are increasing rapidly and facing an acute housing shortage. Traditional apartment procurement techniques involve lengthy lead-times and factory-based, or offsite manufactured (OSM) multi-storey apartment buildings may offer the opportunity to help fulfill the need by significantly reducing build times. Other advantages of OSM may include superior quality, low weight ratios, economies of scale achieved through repetition of prefabricated units, use on infill sites, sustainable design standards and better occupational health and safety. There are also positive labour and training implications, which may help to alleviate an industry-wide shortage of skills through use of semi-skilled labour. Previous uncertainties about the adoption of offsite due to the high capital costs and perception issues were generally based on pre-cast concrete structures, which are quite a different building type in terms of flexibility, construction, delivery and finishes. Identification of drivers and constraints assists in the determination of current industry status, allows for a benchmark to be established and future opportunities and directions for OSM to be determined.

This study aims to propose an assessment model on environmental economics which will provide useful information in making a decision for the implementation of pro-environmental and economical construction projects. To meet the objective, this study suggests a procedure to estimate environmental cost of construction projects. The model combines environmental load assessment and environmental value assessment. The environmental cost of pollutant generated from the construction project was estimated utilizing the Contingent Valuation Method (CVM) which is a value assessment method borrowed from economic science. The devised model is expected to provide a useful methodology that will scientifically support the planning and management of sustainable construction not only in the environmental aspect but also in the economical aspect.

최근 안전취약계층을 상대로 한 범죄가 증가함에 따라 사회적 약자를 위한 안전망 구축에 대한 관심이 증가하고 있다. 이를 위하여 사회안전망 구축 연구성과의 지속적인 실증을 위한 테스트베드를 필요로 하고 있다. 그러나 기존의 지능형국토정보기술혁신사업이나 U-Eco City R&D 사업 등의 테스트베드는 연구개발 성과물을 테스트베드에 적용하여 효과를 검증하는 단계에만 머물러 사업 종료 후 기술의 사업화 및 테스트베드의 지속적인 운영 관리 측면에는 미흡한 점이 많았다. 따라서 R&D성과물에 대한 지속가능한 운영 관리체계 및 제도가 필요한 실정이다. 본 연구는 기존의 테스트 베드 사례와 방범 및 범죄 예방 연구사례를 토대로 지능형 방범 실증지구의 개념을 정립하고, 실증지구 선정기준에 대해 제시하였다. 객관적인 평가기준을 통해 선정된 실증지구는 연구기간 이후에도 지속적인 운영이 가능하고, 시민들의 안전한 삶에 기여하는 실증지구의 표준모델을 확립할 수 있을 것으로 사료된다.

사용자 경험 증대를 위해 증강 현실 기술에 대한 활용이 증가하게 됨에 따라, 다양한 증강 현실 어플리케이션들이 문화유산 영역 대상으로 개발되어왔다. 그간 문화유산 영역에서의 증강 현실 기술의 활용이 극적인 진보를 이루었음에도 불구하고, 단순 증강 방법은 증대된 사용자 경험 제공에 걸림돌이 되었으며, 이를 해결하기 위한 효과적인 증강현실의 특성을 반영한 증강 현실 체험 기법에 대한 연구는 부족한 실정이다. 또한 저작 프레임워크의 부재로 인한 일회성에 그치는 콘텐츠 개발은 지속적인 서비스에 핵심이 되는 콘텐츠 생태계 구축에 저해하고 있다. 이러한 문제들을 해결하기 위하여, 우리는 기존의 사물 중심의 증강 방식을 확장한 공간 주도의 증강현실 체험 기법인 스페이스텔링(Spacetelling) 기법과, 이에 필요한 시공간 연계 콘텐츠를 생성하고 지속적인 서비스를 지원하기 위한 스토리스케이프 저작 프레임워크, 그리고 이를 포함한 유적지 투어 지원을 위한 시스템 프레임워크를 제안하였다. 본 제안의 실제적인 구현 가능성을 검증하기 위하여, 현재 진행 중인 K-Culture Time Machine 프로젝트에서의 구현 사례를 제시하였다. 본 연구의 제안을 통하여 지속 가능하면서도, 향상된 사용자 경험을 제공하는 문화유산 증강현실 어플리케이션을 개발할 수 있을 것으로 전망한다.

Starting with the market vitalization project in 2008, The Gwangju Dae-in Art Market has attracted to many artists, changing into cultural and art market. After the project was carried out for a certain period of time, a study was conducted to determine the differing opinions of the artists and merchants in regards to the market. The study also examined and analyzed the factors affecting the artists' continuous activities. The difference in recognition perception between artists and merchants was analyzed through a T-test. PLS-regression analysis was used for the artists' continuing intention to work. As a result, the artists and merchants recognized that the number of visitors increased after the influx of artists. Programs that had a positive impact on the artist's intention for sustainable activities were as follows: the 'Art Products Creation Workshop', where artists, merchants, and citizens collaborate to develop commodities needed for the market; 'Hanpyeong Gallery', where artists directly or indirectly interact with merchants and citizens; the 'Artist-Merchant Workshop', where artists and merchants produce articles required for the market; 'C'est Si Bon', which expresses the placeness of the market into art; and the 'Dae-in Art Night Market', where citizens, merchants and visitors can sell their own works. On the other hand, programs with the negative effect were those where artists' participation was low or none, as the policy implications, they should be actively develop this type of programs, where artists could participate and interact with citizens and merchants, like this visitors and sales can be increased.

This study aims to uncover what kinds of difficulties preschool teachers are now confronted with when they begin to implement project based learning with young children, in order to develop contents for teacher education programs. From July 2012 to February, 2013, 9 teachers participated in implementing projects in preschool classrooms. For data generation and interpretation, observations of class projects, tape-recordings of teacher conferences, and interviews with the teachers were made. The findings were as follows: teachers' uncertainty regarding project itself, teachers themselves, child competence, and its sustainableness were the most critical obstacle to hinder the teachers in implementing self directed projects with young children. The results imply that the teachers' belief in child competence in doing projects is of great significance; their view that it is very difficult for them to do projects without viewing young children a co-constructor of knowledge. Therefore, the key element in developing contents for teacher education programs should include a richer understanding of young children' competence.

재건축과 관련한 각종 규제들이 강화됨에 따라 향후 공동주택 리모델링사업이 활발하게 이루어 질 것으로 예상된다. 그러나 공동주택 리모델링사업을 수행할 수 있는 관리시스템의 부재로 사업의 어려움을 가지고 있다. 이에 본 논문에서는 리스크관리에 필요한 리스크 인자를 식별하고 분석하여 AHP에 의한 쌍별비교와 리스크 레벨분석을 위한 확률평가를 시행하여 리스크 수준을 제시하였다. 본 연구가 공동주택 리모델링사업의 리스크를 최소화하고 사업을 원활히 수행할 수 있는 기초자료로 활용되어 건축산업의 기조가 신축위주에서 지속 가능한 산업으로 발전하는데 도움이 되지를 기대한다. 향후 연구과제로 본 연구의 리스크 인자분석의 자료를 활용하여 리스크 관리 모델구축이 있어야 할 것으로 사료된다.

Slum settlement, a direct result of the rapid worldwide urbanization is a common site in most developing countries. Uganda is among the top African countries with high number of slums. The status of Katanga slum located in the low-lands between Mulago national hospital and Makerere University is a typical of many other slums within Uganda. This project proposal seeks to tackle urbanization challenges by specializing in slum upgrading as a sustainable way of curbing the menace. An integrated toilet, biogas, poultry and backyard gardening project is proposed as a channel of boosting the Katanga slum dwellers' economic, sanitation and domestic energy status. Designed to serve up to 30 households, the project will utilize residual wastes from poultry houses and toilets to produce biogas and slurry. The biogas yield will provide clean cooking fuel and energy for lighting, while the slurry used as organic fertilizers to improve vegetable yields. The social, economic and environmental impacts of the project will empower the vulnerable women and children within the slums and reduce water pollution and land degradation. This affordable project can be applied in developing countries experiencing slum settlement challenges as a strategy for reducing urbanization pressure.
