Statistics on the occurrence of fires in residential facilities over the past 10 years, show that approximately 40% are fires in apartment buildings. To prevent the spread of fire and support evacuation in apartment housing, the fire resistance performance and performance design of fire doors are becoming more important. This study established a database using 395 quality inspection reports from 2016 to 2020, which passed the fire performance test, and derived the fire door performance-influencing factors through an analysis of the structure (12 elements) of the fire door. As a result, the effect of core material, adhesive, hinge type, blowing agent, etc. was confirmed in 287 pass cases. On the other hand, it was confirmed that the occurrence of flames and crevices in the 108 cases of failure were the major failure factors in the fire door fire resistance test. Fire doors are composed of composite materials to prevent failure of fire resistance performance, and efficient design and quality control are required through standardization of components.

In increasingly competitive market conditions, domestic construction companies are struggling to secure a competitive edge by increasing consumer satisfaction. In these circumstances, a greater emphasis needs to be put on providing an upgraded level of quality in the area of addressing defects to the satisfaction of customers, which is considered to have a great impact on customer satisfaction. This empirical study of the relationships among service quality, customer satisfaction, and repurchase intention aims to provide basis data for increasing service quality, particularly in dealing with the defect issues facing construction companies. To this end, a literature review was carried out on the concept of service quality along with defect issues, and customer satisfaction and influential factors were identified. Building on these foundations and findings, a survey was administered to residents in housing dwellings such as apartments. The results of this study are expected to heighten awareness of the need for increased service quality, which may have a critical influence on customer satisfaction and repurchase intention, and will thereby contribute to enhancing competitiveness and other aspects of the current construction industry.

"SH공사(서울주택도시공사)가 내년 1월부터 '청신호 건축사'라는 이름으로 전문가 인력풀(Pool)을 운영하고, 매입임대를 늘려 신축 리모델링에서 역할을 할 수 있도록 제도화할 계획입니다. 그동안 SH공사가 '주거복지'에 주력해 왔는데, 인공지능과 빅데이터 등을 결합해 앞으로는 한 단계 발전한 '공간복지'로 정책기조를 확대하려 합니다. 이 일을 수행키 위해서 도시설계가, 조경가도 투입될 것입니다." 김세용 SH공사 사장은 최근 서울시 강남구 개포로 SH공사 사옥에서 본지와 인터뷰를 하고, '디자인건축'을 표방한 '청신호 건축사' 전문가인력풀(Pool)을 운영하겠다고 밝혔다. SH공사는 20 30대 청년과 신혼부부에게 공급하는 임대주택에는 내년부터 '청신호'라는 자체 브랜드를 적용한다. 올 1월 취임한 김세용 SH공사 사장은 서울시의 캠퍼스타운조성 시범사업을 총괄 지휘한 바 있다. 이 같은 경험을 토대로 ▲ SH공사 브랜드 가치 제고 ▲ 주택품질 개선 ▲ 임대주택사업 추진 방식 다양화 등을 위한 사업들을 이끌고 있는데, 특히 기존에는 단순히 주거기능만 제공하던 공공아파트를 공동체 생활기능이 접목된 커뮤니티로 발전시키는 '공간복지'를 강화하는데 역량을 집중하고 있다.

최근 정부의 '태양광주택 10만호 보급사업'으로 저압계통 연계형 태양광 발전시스템이 배전계통의 곳곳에 도입되었다. 기존에는 주로 저용량 태양광(3kW 내외)이 1대씩 연계되어 계통에 큰 영향을 주지 않았지만, 최근에는 공동주택 등에 30${\sim}$100대씩 집중적으로 도입되고 있어 여러 가지 문제점이 나타나고 있다. 이와 관련하여 본 논문에서는 50kVA 주상변압기 1대에 2.3kW급 태양광 32대가 연계된 지역의 전기품질을 측정하고 그 문제점을 분석하였다. 태양광 주택단지 인입지점에서 측정결과 전압이 250V를 상회하는 경우도 있었으며, 주상변압기 2차 직하는 태양광이 연계된 A상의 경우 B상, C상에 비하여 약 2V높은 전압을 기록하였지만 그 값은 정상 범위였다. 전압 상승 요인의 분석결과 태양광의 연계용량이 변압기의 용량을 크게 초과하였으며 저압선도 상위 규격으로 교체될 필요가 있었다.

The assembly of the modular housing is an important phase in the construction of pre-fabricated houses. However, the assembly tools that are commonly used in a work site have a disadvantage of decreasing the productivity and the quality. We have developed a exclusive tool for assembling modular parts. The structural stability of the developed tool has been verified in the previous studies. However, the experimental analysis was not conducted. This study analyzed the effect of improving the productivity and quality of the developed assembly tool. The result of the experimental analysis shows improvements in productivity and quality compared to the conventional assembly tool.

Apartment houses are now a popular form of general housing, and the construction techniques and materials quality used to construct apartments are also continuously evolving as if they were representative. However, issues concerning flaws are constantly being reported in the press. This study attempts to analyze the trend of conflicts related to defects and to analyze the types of defects received in the apartment building, to suggest the development of the integrated defect management system, and to develop the construction based on the development of the system.

일반주택지역을 위한 초고속인터넷 제공방안은 xDSL과 HFC 기술방식이 적용되어 왔다. HFC는 전송속도의 기술적 한계를 가지며, xDSL은 기존 동선을 활용하는 솔루션으로 경제적인 장점을 가지지만 동선 선로품질에 따라 품질저하가 발생한다. 이에 UTP케이블이 기포설된 1등급 아파트에만 공급 가능하였던 100Mbit/s 패스트이더넷을 일반주택지역에 공급하기 위한 유사FTTH 시스템이 개발되어 현장에 운용 중이다. 광코어 절감 및 운용유지 측면을 고려하여 WDM-PON (Wavelength Division Multiplexing-Passive Optical Network, 파장분기 수동형광가입자망) 방식을 채택하였으며, 가입자 인근 전주까지 광케이블이 포설되어 ONU(Optical Network Unit)가 설치되며, ONU로부터 가입자 댁내 단말까지 가공형 UTP케이블을 통해 패스트이더넷을 공급하는 방식이다.

Leakage defects account for a significant proportion of defect cases in modular homes. There are factors that can cause leakage defects at each stage, and quality control measures are required to minimize them. An improvement plan to prevent leakage defects was applied from the design drawings to the site of a modular public rental apartment complex in Sejong City 6-3, and a quality control plan was proposed to minimize leakage defects in the remaining process processes.

The maintenance and improvement of housing become more important than quantitative supply. So this paper suggests the directions to solve the current issues of housing improvement policies. In 2015, the housing improvement for the low-income has been expanded with the revision of housing benefit policy. And each related government departments are steadily carrying out various housing improvement programs. Under the current improvement policies, individual houses are being repaired according to the criteria of the target selection. And the repair allowance of the housing benefit is limited to the ownership households except the rented. Hereafter, it has to considered the review of the detailed goal setting and application problems in housing improvement policy and to consider the extension to the rented households and the raise of the income criteria of targets. Also, it needs to carry out the improvement of several neighboring houses at the same time for synergy effect other than individual house, to change the selection way of repair contractors and to secure the quality and advancement of the improvement.

With the government plan to introduce a post-sale system to the Korean real estate market quickly becoming a reality, reformation of the supervision policy under the current pre-sale system is expected. The current supervision policy, designed to enhance the quality of houses and to prevent improper construction, was reinforced through the 'residential construction promotion act' and has been further revised as the 'residential law'. At this current time, the introduction of a post-sale system is expected to affect all aspects of residential construction, from the planning stages to overall conditions regarding the actual construction. Therefore, this research will illustrate several changes in the supervision policy that are expected to arise from the introduction of the post-sale system, focusing on areas of the policy that are presumed to be the most affected. The research will highlight problems under the current system, analyze any domestic supervision restrictions that have been regulated for post-sales that are currently effective, and suggestion methods of improvement in construction supervision system through SWOT analysis.
