More and more domestic skyscrapers have been rapidly constructed to get enough living space for people living in overcrowded cities. The purpose of skyscrapers is to provide citizens with useful facilities and to establish landmarks and also national and regional symbols. Previous studies have been conducted which focused on the structure, materials, plans, maintenance, and relevant information regarding skyscrapers. Skyscrapers, however, are different from other smaller buildings regarding the residential environment as well as in other ways. Recently, several problems have been raised in that the indiscreetness of current skyscrapers cannot guarantee residents a high quality living environment, and they might contain risks unless criteria are put forward to ensure that the design and facilities provide for this aim. It is judged that a set of performance criteria for the residential environment to ensurethe residents' quality of life could solve this problem. This study therefore aims to suggest a method for the improvement of the residential environment of skyscrapers by establishing residential environment evaluation factors. In conclusion, this study calculates the weight of each evaluation factor using AHP (an analytic hierarchy process) and suggests evaluating criteria. It is expected that this study could be used to propose guidelines for residents at the design and planning stage of building a skyscraper.

이방향 중공슬래브 시스템의 구조특성 및 성능평가 연구의 일부로 실제 건축물에 적용된 이방향 중공슬래브의 연직진동을 측정 및 분석하였다. 캡슐형 경량체를 사용한 이방향 중공슬래브가 적용된 두 건축물에서 바닥 용도상 일상적인 진동발생원이라고 가정할 수 있는 75 kg 성인의 보행, 달리기, 제자리 점프에 대해 슬래브의 연직진동을 측정하였다. 두 대상 건축물은 각각 연구소와 교육시설 용도로 설계 및 건축되었다. 측정된 수직 가속도 데이터로 일본건축학회 환경기준에 (AIJES-2004) 근거하여 진동수 범위 3~30 Hz에 대해 1/3 옥타브 밴드 분석을 실시하였다. 이 분석을 바탕으로 AIJEES-2004에 제시한 기준에 따라 바닥의 연직진동에 대한 거주 성능을 평가한 결과, 측정한 세 건축물에 적용된 이방향 중공슬래브 모두 보행과 달리기에 대해서는 피진동자의 10% 미만이 인지, 제자리 점프에 대해서는 50~70% 미만이 인지할 수 있는 것으로 나타나, 이방향 중공슬래브가 바닥의 연직 진동에 대해 거주 성능이 양호함을 보여주었다.

Modular Construction is a method, which factory-produced units are transferred to on-site and assembled to form complete buildings. It is expected that its demand will increase gradually. Because it has some advantages such as duration reduction, movement, reuse and environmental friendliness etc. For the Modular Construction to be introduced and applied, we needs the objective and reasonable performance criteria. This study presents the acoustic performance criteria of the modular building. For this one, this paper reviews legal standard related to performance, analyzes the performance evaluation and survey on pilot projects. The presented performance criteria can be specifically asked the demand by owner in a design guideline. In addition, it makes designer and general contractor accomplish target performance. Eventually, it can improve the performance of Modular Building.

Recently, floor impact sound has become a serious social problem in Korea. There is an increasing need to improve floor impact sound performance using floor covering installed on the floor of apartment houses. KS F ISO 717-2 and KS F 2863 require measurement under conditions in which the resilient material is not installed. But most apartment houses in Korea install resilient materials to reduce floor imapct sound. The performance evaluation method of floor covering should provide reduced performance for use by residents of apartment houses with resilient materials. Therefore, this paper proposes a reduction performance evaluation under the conditions in which a resilient material is installed to verify the performance of floor covering.

The concept of sustainability in residential area is closely related to the notion of amenity, livability, health and interchangeably used with the terms of urban growth management, urban regeneration, new urbanism, urban village movement, compact development, smart growth and the quality of residential environment. Residential Performance Management System (RPMS This system is developed granted by 'Korea Institute of Construction & Transportation Technology Evaluation and Planning' (KICTEP) during 2005-2008.)is a kind of decision making supportive program developed for the evaluation and assessment of various urban performances. It can be utilized for various purposes by many of urban related expert like planner, manager, etc. This study investigate the schematic model for the applying the indicators of quality of residential environment developed by SDI (Seoul Development Institute) using RPMS.

In Korea, fire hazard and risk analysis and response management planning related to existing decrepit buildings, including interior construction and architectural layout revision, due to various occupancy purposes have not been researched or established. Therefore, regulations and technical standards that can manage and reduce fire hazards and risks based on fire hazard analysis and evaluation are required. This study was performed based on a site survey and fire evacuation assessment including performancebased analysis in 3 actual existing buildings to find the life safety issues and provide improvement recommendations.

In this study, distributed the ship's Centralized Air Conditioning System the way an individual to replace the air conditioning system by using Air-cooled air conditioner. Research results, Individually separated air conditioning system complement the heat source control and thermal efficiency problems and improves the efficiency of the device was confirmed. In addition, under the same conditions refrigeration capacity and coefficient of performance of the device, an average of about 3 %, 23 ~ 26 %, higher, Chilled Water Plants Compressor power consumption is about 12 % lower. Also while heating under the same conditions, power consumption is about 33.5 % lower. Therefore Individually Separated Air Conditioning System greatly contributed to the improved performance of the device and living spaces for comfortable temperature and humidity control as well as heating source could be obtained.

The evaluation of the quality of residential environment may be different according to the experts' characteristics. This study aimed at estimating the relative weights of the constituents of a residential environment by AHP(Analytic Hierarchy Process) through experts' evaluation. The respondent group was composed of 72 experts in the fields of architectural design, housing design, urban design, and urban planning. The findings are as follows(:) 1) the relative weights of residential constituents were different between detailed fields ; 2) the relative weights of residential constituents were not different according to institute in which experts are engaged ; and 3) for the practical application of estimation results of the relative weights, the relation between residential performance constituents and physical design elements should be considered in future.

This paper proposes a design plan of short-term temporary housing for the victims by disaster. Also construction workability and residential environment evaluated by mock-up. In particular, in the event of a disaster, victims have lived the auditorium or gymnasium of the nearby school which is an emergency shelter. However, there was a problem of livability. Therefore, it is the purpose of study to provide temporary housing that resides within 30 days. For this purpose, a composite panel with light weight and insulation select to produce mock-up. The mock-up complete in about an hour. This is because it is made only of the composite panels. The composite panels confirm to be easy to load and construct. And mock-up evaluates insulation and waterproofing performance in the laboratory. As a result, Mock-up has insulation and waterproofing performance. This suggests an alternative to short -term temporary housing.

본 연구에서는 기존의 공조방식 및 본 연구에 제안된 개별환경제어시스템(PEM)으로부터 재실자가 거주하여 사용하고 있는 컴퓨터룸(CR)에 대해 기하학적으로 3차원 시뮬레이션을 수행하여 CR의 열취득과 재실자 온열 쾌적감을 감성공학적 측면에서 분석하였다. 본 연구로부터 바닥으로부터 공기를 유입하여 천정으로 유출하는 바닥취출공조(TAM)방식이 실내 환경 개선에 유리하고 디퓨저만을 통하여 공기가 유입되어 천정과 바닥으로 공가가 유출되는 개별공조(PEM) 방식은 열적 냉각 성능은 좋으나 컴퓨터와 재실자 주변에 강력한 ㅐ순환 유동을 유인하여 실내 환경의 쾌적감 측면에서는 불리하다. 그러나 PEM과 TAM방식의 결합이 감성공학적 온열특성 분포로부터 CR의 재실자 주변온도 분포에 최적임을 알 수 있다.
