This paper investigates housing defects and housing satisfaction of the aged according to the personal characteristics and their housing environment. Personal interview was made on the 280 senior persons living in Jeonbuk area. Research results are following. Low levels were found in education, self privately-owned property, monthly income. Most of them live in a detached house that is outdated and obsolete. The facility defects of housing were the most serious level in case of the female senior citizen who lives alone. Their house aging was old but had the high deviation among households. Main influencing factors on facility defects of housing were perceived economic status and ownership of house, the next was age of the aged. Main influencing factors on the housing satisfaction were perceived economic status. Housing satisfaction was higher, the better economic level of the aged was, male than female, the less the age was, in case of hot-water usage in bathroom, owner of houses, no difference in floor level, larger storage space of kitchen was. According to the empirical results, we propose the supporting policy of hosing safety for the aged in order to reduce the risk and social cost. Especially the rate of population aging, the aged household, and the detached houses are higher in Jeonbuk rural areas than the other area. Housing facility defects of the elder who lives alone and house aging of theirs are serious level. Local government should have supporting system that considers local difference and characteristics of the aged housing.

This study proposed how to identify window defects by using photos uploaded by occupants during the pre-handover inspection of mulch-family housing. A total of 1168 door images were acquired to generate training data and validation data. Subsequently, through the proposed algorithms, every pixel in images labeled a door was binarized using the OTSU threshold, and then dark pixels were identified as defects. Experimental results demonstrated that our computer vision-based defects identification method detects the door with a recall of 57.9%, and door defects with 63.6%. Although it is still a challenge to automatically identify building defects because of the distortion and brightness of photos, this study has the potential to support better defects management. Ultimately, the improved pre-handover inspection may lead to increased customer satisfaction.

입주민은 육안으로 구별이 되는 하자를 중심적으로 보며, 건설사는 공동 주택의 구조적, 기능적 문제에 영향이 가는 하자를 중심적으로 본다. 그에 따라, 건설사와 입주민은 공동주택의 하자를 기준으로 서로 다른 관점을 가지고 있다. 이를 해결하기 위해 본 연구에서는 서로 다른 하자의 관점차이로 인하여 발생하는 공동주택 하자분쟁의 쟁점과 개선 방안을 목표로 진행하였다. 먼저, 국토교통부와 법원의 서로 다른 하자판정기준 및 보수기준을 분석하였다. 과거 청구소송 하자판결 사례분석을 통하여 문제점을 도출 하였으며, 여러 건설사의 하자 데이터를 기반으로 건설사와 입주민의 관점차이를 도출 하였다. 이를 해결하기 위해 공동주택 하자 데이터베이스의 개선방안을 제안하였다.

The purpose of the study was to investigate defect cases in residential interior design, to identify the state of defects, and to categorize types of defect and disputes. In addition, consumer appraisal to residential interior design service were analyzed. The results of this study could provide fundamental information regarding the defects and claims in residential interior design. First, we did literature review for defect disputes in architectural design and interior design. We identify the definition of defects by building life cycle, by state of construction, by activity, and by design performance. Second, we analysed interior design defects cases reported in Korea Consumer Agency & Ministry of Land, Infrastructure and Transport. A total of 49 cases of defect disputes in residential interior design from 2000 to 2015 were investigated. As a result, many defects appeared during the construction stage. A majority of defects cases fall into insulation, water-proofing/leakage work. In terms of design aspects claim, functional and aesthetic defects were claimed. Third, from Consumer Market Evaluation Indicators, raw data from 500 respondents were investigated for the housing repair and interior design. It is found that information comparability, responsiveness to consumer claim, price, and safety are important factors for consumer satisfaction in interior design.

Recently, defects that occurred during the construction of apartment houses have become a social issue. Defects in apartment houses lead to waste of resources and economic loss, causing psychological and physical damage to customers, and a decrease in reliability and financial loss to construction companies. The purpose of this study was to analyze the impact of defect occurrence according to the difference in project management level in the apartment housing construction stage, and to investigate the extent to which the project manager's experience affects the defect occurrence rate. For the empirical analysis of the study, statistical analysis was conducted using data collected from 130 actual projects. The results of the analysis showed that schedule management, cost management, and quality management had a positive effect on reducing the defect occurrence rate in the execution stage of apartment housing construction, while human resource management productivity had a negative effect. This study theoretically demonstrated the importance of project management, and in practice, showed that schedule management, cost management, and quality management should be faithfully performed in the execution stage to reduce the rate of defects after project completion. It was also suggested that hiring an experienced project manager would help reduce project defects.

This study intends to predict prospective defects and establish the plan of Preventive Maintenance through research and analysis of defect occurrences and their repair costs in the public equipment of ‘H’ apartment house from 1998 to 2001. According to results of the analysis, more than 90% of defects and their repair costs for 4 years of the building have occurred in heating, hot water and water supply equipments. In case of specific classification in each equipment, more than 60% of defects were found at hot water pipes and heating pipes, and their repair costs covered more than 60% of the total defect costs. After two repairs by ‘Preventive Maintenance’ had been performed in the year 1998, total defects and defects of each equipment each yew have increased in number from 1999 to 2001. But total repair costs and repair costs of each equipment have not increased as time has gone by, because repair costs have relationship with the price of materials and labor, the part of defect and the scale of repair.

The purpose of this study is to classify defects of the residential building by analyzing the defect specified by prequalification of residential building reconstruction and to suggest the solution of the problem which can be arisen during each stage of plan, construction and maintenance. By sorting the main defects which is specified by pre-qualification of residential building reconstruction for three years from August 2006 to August 2009 into 4 catagories and analyzing the cause of the defects, we draw the way of maintenance to prevent the defects and make pleasant residential environment. The reason for the frequent defects from residential building is mainly deterioration. It occured on the finishing more than on the structure, which means that residents can find defects easier on the finishing than the structure and clear the demand for repair. The result of analyzing of pre-qualification of residential building reconstruction is that the defects mostly caused small, masonry constructed and lower apartment. The apartment which is not into legal right for maintenance naturally have more defects than the others. In conclusion, it is necessary to establish a law of obligation duty of the maintenance of small apartment.

In this paper, research on the mold design of motor housing produced by the HPDC process was conducted using computer simulations and experiments. Recently, automobile parts have been required to be light and have high strength. The die casting process was used to manufacture automotive motor housings. In the die casting process, the control of casting defects is very important. However, it has usually depended on the experience of the foundry engineer. For the analysis of the manufacturing process of motor housing, the finite element method is applied. Through the simulations using commercial software, the filling pattern and product defects could be confirmed. The analysis results obtained from the filling behavior of the casting process agreed with the experimental results. The computer simulation results of filling behavior were reflected in the optimal mold design of motor housing.
