Construction waste is recycled and used for the efficient and eco-friendly disposal of construction waste increasing due to reconstruction and redevelopment project and so on. There is recycled aggregate as a typical case. And this recycled aggregate shows strong alkalinity due to calcium hydroxide, and causes many environmental problems. Therefore, this is a study on reduction in the strong alkalinity of recycled aggregate by using phosphate of ammonium in order to reduce the pH of recycled aggregate. Besides, a possibility that a pH reducing agent of recycled aggregate could be applied to a site was evaluated. As a result, it was possible to verify that pH decreased as the percentage of pH reducing agent increased. It is thought that the pH reducing agent can be applied to a site by methods such as immersion and spray using the pH reducing agent in the process of producing recycled aggregates.

After 1980's, as economy was rapidly grown and real estate market was active, greatly increased in population has been supplied to the city. Accordingly, national apartment house market is located in the form of Urban Housing Culture. However, as time goes by the apartment houses where the supply of mass became superannuated and residential environment became poor. So, the environment of old apartment houses has been changed to improve with reconstruction. It has been changed in response to the demands of the times. It is one of essential part in a remodeling field for the future although it has some problems in the way that uses existing buildings.

The Seongdeok Divine Bell(nicknamed "Emile Bell") represents the bell of the Silla dynasty. However, ringing it was stopped since 2003 for the safety of the bell. Currently, Kyungju city is performing a project casting a new great bell(tentatively named "Great Bell of Silla") that inherits the beautiful appearance and the sound of the Seongdeok Divine Bell in order to ring a new coming millenium. The new bell is designed to be almost same as the Seongdeok Divine Bell in terms of size, weight and shape as well as its sound. In this study, we investigate the problems occurring in the design of the bell structure and propose the design strategy for the reconstruction of the traditional large bells.

Hoe beak village (Donggu manseokdong, Akasaki Village) is the oldest slums in Incheon. Recently, 'Mixed residential environment improvement project' is being promoted as Aboriginal entire resettlement goals in place of 'new building reconstruction and redevelopment projects' knock down everything this hoe beak village existed already. Resident representatives meeting configuration goes, but still do business magazine in the right direction. Therefore, in this study, the proposed architectural solutions to meet the demand of residents on the research problems, performed in a manner that the local improved hoe Buri village residential environment improvement projects and analyze the current situation and characteristics. In this study, the following improvements are presented. Prepare guidelines and maintain design guidelines for maintaining the identity of the village, Improve continuous landscape of the village, Construction of mixed-use sanitation facilities, Using a mini-lot and Vacant for Ssamzie Park Development, Units of housing types for Shared housing and co-operation are proposed.

The contemporary educational system in South Korea is built on high-stakes standardised tests, a manifestation of the national project of social reconstruction and reform. One recent outcome is the emergence of an unfamiliar yet ubiquitous phenomenon: the "pig mum"; a Korean parent who is fully involved in organising, scheduling and managing the educational process from primary to secondary school for a group of children in a neighbourhood. Based on a quasimixed method utilizing a survey of a group of students and parents, this pilot study explores the "pig mum" phenomenon and its linkage to education policy. The authors conclude that the current educational policy fails to achieve the ideals it professes to value. This creates deep and negative societal norms that endanger a growing generation of students by creating a parallel private education market environment where "pig mums" thrive.

Study from Yogyakarta earthquake reconstruction program, cast-in-place wall using fix-size formwork system (Old-CIP) has offered a good alternative for house construction. A simulation has also confirmed that this system using mortar as the main material can provide cheapest cost and lowest total man power compared to conventional wall construction technique: brick or mortar-block wall. This paper presents the new wall construction technique: full size cast-in-place wall (New-CIP). The detail of how this new technique implemented is described. In addition, considering that material and labor cost in one area is different to others, cost analysis for different resources prices and wages of three cities are taken into a simulation. The analysis is aimed to distinguish the implementation feasibility of New-CIP system compared to the four common wall systems. Finally, its implementation resistance is also discussed.

The purpose of the study was to investigate state and problems of Seongnam Jungang Market that lost competitiveness under rapidly changing logistics environment, and to give market redevelopment model, project validity and operation management plan considering commercial area and location of the market. The public market at the community that has tradition and culture of the residents provides small merchants with employment chance and to let residents buy daily necessities. The market allows farmers to sell agriculture products by themselves and to increase income. Most of public markets that open every five days help residents meet each other to exchange information. Most of public markets have been placed at local towns and rural areas to lose distribution functions remarkably at less population and quick aging.

Building deterioration reflects the degradation of basic building performance including structural performance, energy performance, durability, and safety, and it also includes perceived deterioration, which considers a user-based perspective. More than 50% of the existing buildings in Korea are over 15 years old and public buildings compose 2.5% of all buildings domestically. Therefore, there are several different problems, such as poor energy efficiency, structural performance, and safety. To address the challenges of increasing stock in deteriorated buildings, it is necessary to make decisions about reconstruction or renovation. In this study, we propose a new method to evaluate public building value with a contingent valuation method (CVM). By estimating willing-to-pay (WTP) from users of private buildings in similar situation with the public building, it is possible to compare market prices and calculate a correction factor to adjust the WTP data. Finally, we apply the correction factor to the WTP of a public building and estimate market price, willingness to pay (WTP). Finally, we apply the correction factor to willing to pay (WTP) of public building and estimate market price.

With the recent global trends in environmental preservation, the importance of sustainable construction is being highlighted in Korea. In particular, the trend is being discussed about life cycle of the apartment houses in various aspects. However the Korean construction market and housing policy have been increasingly focusing on supplier. Structures become progressively obsolete after a certain period, but their durability can be extended with proper maintenance management. Accordingly, if maintenance management on the structures is made efficiently, waste of construction energy and damage to the environment and economic loss due to early demolition and reconstruction can be effectively prevented. Therefore, this study aims to suggest the user manual design for the efficient maintenance in apartment housing

정부의 주거복지 로드맵(2017.11.)에서 도심에 위치한 중저밀도 노후 영구임대단지를 고밀도로 재건축하여 공공임대주택 공급을 확대하는 방안을 제시하였다. 이러한 방안은 재건축 타당성이 낮은 단지에 대한 리모델링 사업이 공공임대주택 공급을 위한 대안으로 인식된다. 그러나 공공임대주택 사업자가 리모델링 사업 추진을 위한 사업성 평가방법, 사업방식의 결정 절차 등이 미비하여 사업추진이 어려운 실정이다. 이에 본 연구에서는 기획단계에서 노후 장기공공임대주택 리모델링 사업의 예측 가능한 사업구조 수립을 위하여 사업성, 건축계획, 도시·주거환경계획, 법 제도 그룹으로 구분하여 영향요인을 분석하였다. 각 그룹별 주성분 요인을 도출하고 가중치 분석을 하였다. 그리고 주성분 요인의 세부영향요인에 대한 상대적 중요도 점수(RIS)를 산정하여 중요 영향요인을 선정하였다. 추가적으로 중요 영향요인 중 정량적 요인을 활용하여 리모델링 사업 검토를 위한 프로세스를 제안하였으며 서울특별시에 위치한 33개 장기공공임대주택을 대상으로 리모델링 사업이 가능한 단지를 선정하는 방법으로 제안한 프로세스의 실무활용성을 확인하였다. 본 연구의 결과는 공공임대사업자가 장기공공임대주택의 리모델링 사업 계획 수립 시 유용하게 활용될 것으로 기대된다. 다만 본 연구에서는 제시된 중요 영향요인 중 정량적인 요인들에 한하여 실무활용성을 검증하였다. 이에 향후 정성적인 요인들의 활용 및 검증 방안에 대한 연구가 추가적으로 필요할 것으로 판단된다.
