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.

자율주택정비사업은 노후저층주거지 개량을 위한 소규모주택정비사업의 유형 중 하나이다. 본 연구는 자율주택정비사업이 일부 지역에 편중되어 시행되는 점을 확인하고 현재까지 추진된 사업 세부내용의 지역별 차이를 비교 분석하고, 사업추진의 지역차 가 발생하는 원인을 설명할 수 있는 이론적 접근방법을 탐색하는 것이 목적이다. 이를 위해서 자율주택정비사업의 개념과 특성에 대해 살펴보고 자율주택정비사업 및 관련 분야에 대한 선행연구를 검토한 후, 2018년 이후 준공된 전국 자율주택정비사업 추진현황 을 지역별로 비교 검토하였다. 그 결과 사업 특성 중 사업면적, 사업성에 영향을 미치는 요인, 사업 소요기간이 지역별로 유의한 차이가 있다고 분석되었다. 이론적으로 이러한 지역 격차는 중앙정부의 정책을 지방정부의 도시관리자가 실현하는 과정에서 지역에 내재한 제약과 행위 특성이 반영된 결과로 해석할 수 있다. 연구결과는 향후 자율주택정비사업 활성화를 위한 법령 등을 개정할 때 직접적이고 실증적인 근거자료로 활용될 것으로 기대한다.

This study explored factors that affect the risk of excluding the support due to recidivism of the recipients within the support period of the housing support projects among the rehabilitation protection projects of the Korea Rehabilitation Agency. The subjects of this analysis were released prisoners who applied and supported by the project from 2005 to September 2009. Continuous survival analysis was used to supplement the limitations of existing logistic regression analysis for the loss of information about the duration of an event (recidivism). The summary of the analysis results is as follows. First, 2.76 % of all recipients of the housing support projects were excluded because of recidivism within the support period. On a three-month basis of analysis, the risk ratio was the highest at 0.0046 (0.46 out of 100) over 7-9 months period. In addition, the cumulative risk ratio of the entire period showed that if the recidivism is not committed for over six years after the start of the support, the likelihood of excluding the support in the future is quite low. Next, the results of the cox regression analysis affecting the risk of exclusion of support due to recidivism showed that health conditions, number of convictions, and the type of committed crime had statistically significant effects. Specifically, those who are in good health, have two or more criminal records, or have a history of village affairs, were found to have increased risk of excluding the support compared to those who are not. Finally, the interpretation of the above results and policy implications were discussed in conclusions and suggestions.
