More than half of Korea’s urban population currently lives in multi-unit dwellings. This particular residencestructure inevitably positions the living spaces of residents in close proximity to one another. Because of thisproximity, the sounds of a particular household will transfer to other residents’ units creating conflict between tenants. Efforts to alleviate this problem have been made in both the public and private sector. A prominent method of noiseanalysis between living units has been to make an actual sound measurement and obtain qualitative measurementsfrom questionnaires. Although this method has been most widely used, such analysis requires a large amount ofhuman effort and time. In addition, the questionnaire method fails to provide the objective information needed toaccurately assess the noise situation. To overcome the inadequacies of this previous method, this study seeks toevaluate the applicability of an acoustic simulation method. Three types of living noises were analyzed to assess thenoise levels passed between multi-unit dwellings. The acoustic simulation method was found to be more economical,efficient, and adaptable in information processing. The results of this study can be further applied to design andcontrol living-noise through procedures such as acoustic absorption or space redesign.

AHP 분석을 통한 판교 환풍구 붕괴사고 요인분석

양기남,김광희 한국방재학회 2015 한국방재학회논문집 Vol.15 No.6

Collapses of building structures or facilities have been frequently reported in recent years. A structural collapse can cost many people’s lives. Mauna Ocean Resort Collapse and Pangyo Techno Valley Vents Collapse are key examples of this kind of incident. In the former, 10 people lost their lives, while 16 people were killed in the latter incident. However, there have been few studies to analyze the causes of these recently reported disasters. In this study, each of the accident factors of the Pangyo Techno Valley Vents Collapse was quantitatively analyzed by using a hierarchical analysis method. In the analysis result, faulty construction items including construction factor and inspection negligence in the construction process were evaluated to have a higher priority. It is expected that the findings of this research can be utilized as fundamental data to prevent a structural collapse. 최근 시설물에서 다수의 사망자가 발생하는 대형 재난이 빈번하게 발생하고 있다. 대표적인 대형 재난의 사례로 10명이 사망한 마우나 리조트 붕괴사고와 16명이 사망한 판교 환풍구 붕괴사고가 있다. 그러나 최근 발생된 재난을 바탕으로 사고요인을 분석하고자 하는 연구가 부족한 실정이다. 따라서 본 연구에서는 대표적인 재난 사례인 판교 환풍구 붕괴 사고의 사고 요인을 바탕으로 계층분석 방법을 이용하여 각 사고 요인들을 정량적으로 분석하여 그에 따른 관리의 우선순위를 제안하였다. 그 결과 감리적 요인이라고 평가되는 시공과정의 확인 의무 소홀 항목과 시공적 요인이라고 평가되는 부실한 시공항목에 대한 우선순위가 높았다. 본 연구 결과는 추후 대형 재난을 예방하기 위한 기초 자료로 활용될 것으로 기대 된다.

임금체불 해소절차에 대한 건설근로자 인식 분석

양기남 ( Yang Gi Nam ),김광희 ( Kim Gwang-hee ) 한국건축시공학회 2016 한국건축시공학회지 Vol.16 No.6

2014년 기준 29만명의 근로자가 전체 1조 3천억원의 임금체불을 당하는 것으로 나타났으며 특히 노동집약적 산업인 건설산업의 특성상 임금체불로 인한 부작용이 심각한 실정이다. 그럼에도 불구하고 임금체불 해소를 위한 연구는 근로자의 인식을 배제한체 임금체불 해소제도 개선에 주안점을 두고 이루어 지고 있다. 따라서 본 연구에서는 임금체불 해소를 위하여 근로자의 인식에 기반하여 임금체불 해소절차에 대한 실효성을 분석하고 근로자들의 인식을 파악하고자 한다. 연구 결과 전체 근로자 및 관리자의 30% 이상이 임금체불 해소절차 및 해소제도에 대하여 전혀 인식하지 못하고 있었으며 연구체불 해소를 위한 제도 또한 많은 개선이 필요한 것으로 나타났다. Wage is a very important issue not only for the workers` current living but also for the future laboring landscape. As of 2014, it is reported that about 290,000 workers suffer from delay in payment of wage. The construction industry is particularly labor-intensive, which implies that delay in payment of wage is a serious problem. Despite this fact, in terms of the delayed payment of wage most studies have been conducted on the improvement of a system to resolve delayed payment in exclusion of labor workers` awareness and thinking. Thus, the purpose of this study is to understand construction labor` awareness and analyze the effectiveness of the resolution step of the delayed payment of wage based on construction labors` awareness. In the research result, more than 30 percent of all construction labors and managers are never aware of the settlement procedure of the delayed payment, and it appears that the resolution step system needs to be greatly improved. In conclusion, it is expected that this study will be utilized as fundamental data for the settlement procedure of the delayed payment, and the influence of delayed payment on construction labors` safety behavior and productivity should be further studied in the future.

메타분석은 여러 실증연구의 정량적인 결과를 통합과 분석을 통해 전체 결과를 조망할 기회를 제공하는 통계적 통합 방법이다. 전자상거래 연구에서 만족, 신뢰와 충성도 간의 관계에 관한 연구들을 문헌연구와 메타분석을 실시하였다. 최근 전자상거래나 정보통신기술과 지식정보사회의 융합은 정치, 경제 및 다양한 분야에 빠른 영향을 미치고 있다. 본 연구는 2002년부터 2013년까지 우리나라 학술지에 게재된 연구 중 만족, 신뢰 및 충성도의 인과관계가 설정된총 57편의 연구논문을 대상으로 하였다. 메타분석의 결과 만족과 신뢰의 경로가 가장 큰 효과 크기로 나타났으며, 효과 크기는(r = .591)이었다. 두 번째 효과 크기는 만족과 충성도 경로에서 효과 (r = .554), 다음으로 신뢰와 충성도 경로에서는(r = .552)로 나타났다. 그런데 신뢰와 만족 경로에서는 가장 낮은 효과 크기(r = .484)로 나타났다. A Meta-analysis refers to a statistical literature synthesis method from the quantitative results of many known empirical studies. Recently, the convergence of knowledge-based society and, information telecommunication technologies has a rapid impact on politics, economics and various fields. A meta-analysis was conducted to identify the relationships among satisfaction, trust, and loyalty in e-commerce studies. A total of 57 research papers published in Korean academic journals during 2002 and 2013 were reviewed and the causal relationships among satisfaction, trust, and loyalty in e-commerce were established. The result of the meta-analysis might be summarized that the highest effect size (r =. 591) was in the path from the satisfaction to the trust. The second biggest effect size (r =. 554) was found in the path between the satisfaction to the loyalty. The third biggest effect size (r =. 552) was found in the path between the trust to the loyalty. By the way, the smallest effect size (r =. 484) was found in the path between the trust to the satisfaction.

According to the increase of foreign laborers at domestic construction sites, it's necessary to research in terms of the unsafeacts of both Korean and foreign laborers in order to prevent construction disasters. The objective of this study is to clarify thecharacteristics and the improvement priority of the unsafe acts using IPA(Importance-Performance Analysis). The result of this studyshowed which items of unsafe acts are identify difference between Korean and foreign laborers. Moreover, the result of IPA also showeditems of unsafe acts that needed the immediate improvement for each one. Especially there are two items, i.e. equipment malfunction andwrong handling of hand tools, which both Korean and foreign laborers think simultaneous those needs improvement. The results can beutilized to plan and to improve the safety management and education at a site considering the characteristics of foreign laborers -

This paper presents a case study to develop e-learning contents of agricultural safety based on the assessment of risks of 4selected crops and stock farming: rice, potatoes, apples, tomatoes and stock raising. The aged farmers, who are main workforce of currentKorean agriculture and relatively more vulnerable to various risks of agricultural work compared to younger workers, were considered asthe main users of the contents in developing them. The safety guidelines were presented as simple as possible and the interfaces weredesigned to be simple and easy to use so that the older users can use it without much difficulty. In making the scenarios of the contents,risk assessments were carried out for each crop and stock farming with the focus being on occupational diseases rather than accidentalinjuries. To make the contents more attractive to the farmers, the functions requiring active responses from the users, such as answeringsimple questions, were included in the contents. Usability evaluation by experts of ergonomics and agricultural tasks were carried out inmodifying the draft version, whereas formal usability test was not included in the case study. Though there are some limitations in thedeveloped contents in the aspects of evaluation of usability and effectiveness, this case study shows the structured procedure ofdeveloping e-learning safety contents based on the risk assessments on agricultural tasks. The developed e-learning contents are expectedto be used practically and easily in educating and training older farmers about safety and health of agricultural tasks.
