Under climate change and urbanization, rainwater harvesting (RWH) systems are emerging as an alternative source of water supply because of growing concern about water sustainability. RWH systems can satisfy the various watering needs and provide the environmental benefits of lessening the damages from flood, drought, and runoff. The economic success of a RWH system is vitally concerned with the determination of the design capacity of storage tank to be built in the system. The design capacity is determined by the factors of average annual rainfall, period of water scarcity, and water price during the whole life-cycles. Despite the high uncertainties inherent in these factors, the current engineering design of RWH system construction often assumes that storage tanks should be built all at once. This assumption implicitly ignores the managerial flexibility in responds to the future as new information comes out-the right to build storage tanks stage by stage depending on the evolution of demand. This study evaluates the value of a multistage storage tank construction using a real option approach. A case study involving a typical RWH system construction in Jeonju, the Republic of Korea is conducted. The managerial flexibility obtained from the real option perspective allows engineers to develop investment strategies to better cope with the issue of water sustainability.

This paper summarizes some of approaches that could be taken for data exchange in a non-interoperable work environment and reports lessons learned from the Dongdaemun Design Plaza and Park project. Today's widespread application of building information modeling (BIM) to the construction and architectural design industries requires a change in the cooperation between business organizations and their methods of communication. In particular, the interoperability of information between interdisciplinary organizations, which use specific programs for different purposes, has become a critical issue. More than just a technical problem, it is also highly related to an organization's collaboration culture and the particulars of a specific project. This paper describes the interoperability issue that occurred during the construction documentation phase of the irregularly shaped building project, Dongdaemun Design Plaza and Park, designed by Zaha Hadid Architects and Samoo Architects and Engineers, from the perspective of the technological problem and the collaborative organizations' communications. Although the perfect compatibility of information is not possible, this paper deals with a practical approach to the interoperability issue by examining the way the end-users of computer-aided design (CAD) resolved the interoperability problems in practice.

설계단계에서 구조적 안전성을 확인하더라도, 시공단계에서는 구조시스템이 완전히 형성되지 않아 구조적 안전성이 보장되지 않는다. 또한 시공 기간은 완공된 이후의 건물의 사용기간보다 짧기 때문에 설계단계에서와 같은 지진하중을 시공단계에 적용하는 것은 과다하다. ASCE 37-14는 시공 중 지진하중 저감계수의 개념을 제시하고 있지만, 명확한 적용 방법을 제공하지 않고 있다. 따라서, 이 연구에서는 재현주기에 따라 저감한 지진하중을 주거용 중층 RC건물의 예제 모델에 적용하였다. 예제모델의 시공단계를 5층 단위로 구분하였으며, 시공단계 모델들에 재현주기 변화에 따른 지진하중을 적용하여 시공 중 지진하중을 분석하고 구조 부재의 단면성능 검토를 수행하였다. 설계단계와 시공단계에서의 전단벽 설계강도비를 비교하여, 주거용 중층 RC 건물의 시공 중 안전성을 확보할 수 있는 지진하중 크기의 범위를 재현주기의 관점에서 분석하였다.

The program of practical training of architectural interior will be change for improvement of not only to complete design on the table but to be in employee market flexibly also. It's necessary to take the educational efficiency for the practical training in the course of intoner architecture. The characteristic of interior space in the model for useful practice is residential space. the interior construction to be controled generally on the central axis of interior architecture, although there were several items of construction which divided architectural structure, electrical power, air control est. the process of practical training is to be established not only with object of training, grade of skill, materials and equipments and tools of it's prepare and working, but safety on the job training.

Recent time, there appear many cases of remodeling construction concluding enlargement of exclusive using area in Apartment. These constructions show several phases according to the size of apartment and use of the each room. In small size apartment the cause of enlargement construction is usually the desire for having enough dwelling space. But in large size apartment that is usually the desire for having usuful and effective dwelling space. In these remodeling constructions owner or designer change the interior design of each rooms and the Intoner materials. These changes show several tendencies by the sizes of apartments and use of the each room.

본 연구는 도급공사의 공격적인 저가 수주로 인한 공사비 부족을 만회하기 위해 설계변경 등 자구책이 뒤따르게 되고, 이러한 과정에서 시공상의 하자가 유발될 수 있다는 점에 대하여 재무적 자료를 이용하여 실증분석하는 것을 목적으로 한다. 연구 결과, 공격적인 수주행위로 인한 수주량의 비상적인 증가와 영업이익률 등 수익성 악화는 공사 품질의 저하와 하자 발생으로 이어진다는 것을 확인하였다. 또한 시공눙력이 낮거나 공사 착공 후 설계나 계약 조건을 변경하는 경우 하자발생의 직접적인 원인이 된다는 것도 확인하였다. 공격적인 저가 수주와 하자 발생 사이의 관련성을 확인함으로써, 하자발생을 방지할 수 있는 방안을 마련하는 계기가 될 수 있다.

The purpose of this research is to develop the technology to meet the requirements of the design content, and to build a 'Requirement Information Management Model' for the design project. The model that should be used in the early design stage will undergo the following process: First, basic requirements would be defined by extracting the design content in the form of a reusable library of space units. At the next stage, requirement information should be modified after considering unique characteristics for the project and conflict problems between function and performance.

The constant evolution of society, culture and scientific technology, coupled with changes in life style and behavioral patterns, has led mankind to peroeive diverse needs for space. Particularly, the rapid structural change in the field of marketing has entailed changes in techinques for construction and presentation of space for an improved marketing environment. To satisfy such new, diverse needs for space, interior designers will have to redefine the "mankind and environmen( concept and examine their design methodology anew. The question of how to design available space for a certain purpose will remain a daunting task for designers in the future, as it has been in the past. In the pursuit of convenience and conformity to mankind's surroundings, every nation has, in common with other nations, basic design elements, design skills and other factors. In designing camercial space in a particular region, it is essential, however, to have a proper understanding of the social economic and cultural context indigenous to that region, as well as the impact on environmental and ecological change and marketing strategy. This study discusses design metholdology for the comming camercial space on the basis of the space concept and current status in Korea, with major emphasis on Korea's regional characteristics.
