1997년 11월 대외지불 불능사태로 시작된 외환위기가 경제위기로 확산되면서 97년 4/4분기에는 2.5%에 불과하던 전북지역의 실업률은 99년 2월 8.4%로 피크를 이루었으나 그후로는 감소추세를 보이고 있다. 그렇지만 전북지역 노동시장의 전반적 고용동향을 살펴보면 실업률 통계로는 파악되지 않지만 실질적으로 준실업상태에 있는 실망노동자와 불완전취업자의 증가가 심각한 것으로 드러났다. 그리고 산업별 취업자 구조의 변화를 살펴보면 제조업과 건설업의 취업자 감소가 두드러졌으며, 농업부문이나 생계형 서비스업은 실업대란 시대에 완충역할을 해줄 것이라는 기대와는 달리 고용흡수력이 예상보다 훨씬 적은 것으로 드러났다. 취업과 실업 및 비경제활동 사이의 노동력 전이률을 살펴보면 남성과 핵심연령층에서는 취업정착률이 높지만 일단 실업자가 되면 실업으로부터의 탈출률이 낮은 것으로 드러났다. 반면에 여성의 경우에는 실망노동자(discouraged sorkers)효과로 인하여 실업률은 낮고 비경제활동으로의 이동이 크게 나타났다. 그리고 실업이나 비경활상태로부터의 (재)취업시에는 압도적으로 임시고/일고로의 취업이 많아서 98년 하반기 이후 전북지역에서 창출된 일자리가 주로 임시고/일고 위주로 이루어져 있음을 극명하게 보여준다. 한편 여성실업자의 경우 50%이상이 생계주책임자이며, 특히 여성가장 실업자의 경우에는 90%이상이 생계책임자이나 그들 대부분이 빈곤선이하에서 생활하고 있다. 그리고 전북지역에서는 전국수준에 비해서 장기실업률이 다소 높게 나타났다. 저학력층과 고령층, 생산직, 임시고일고등의 비정규직 실업자들의 구직기간이 긴 것으로 나타났다. 실업이 장기화되면 전반적으로 기간의존성효과(duration dependence effect)나 이질성효과(heterogeneity effect)로 인하여 재취업의 가능성은 더욱 떨어진다. 생산적복지(workfare)가 그 이름에 값하는 것이기 위해서는 시장경쟁력이 약한 취약계층에 대해서 직업훈련과 취업알선 및 채용장려, 공공근로 등의 제반 정책들이 가구되어야 할 것이다.

In the previous comparative studies of international competitiveness conducted before 2003, Korean construction productivity had been estimated to be lower (or poor) than that of developed countries such as US, UK, and Japan. However, the amount of international contracts Korean has won increased substantially, and Korean construction has progressed with creating two skyscrapers such as Petronas Tower and Burj Dubai. At this point we need to reevaluate what we are capable of. In this paper, we evaluated international competitiveness of our construction industry comparing to advanced countries by analyzing labor productivity. For evaluating construction competitiveness we measured labor productivity using the value of construction work in US dollar per hour based on domestic and foreign statistical data and analyzing completion days per a story and the ratio of underground floors to ground floors of buildings in Korea and Japan. As a result, although our construction productivity is not yet competitive with the US and Japan yet, we excel the UK.

The Korean society faces a new issue of accepting foreign workers. Foreign labors in construction industry reached about 400,000 recently. Thus they have become one of the essential resources to fill up insufficient labor supplies in construction industry. And it is important how to manage foreign labors efficiently. However there are few studies focused on this subject. Purpose of this study is to research productivity of foreign labors in the domestic construction site. So investigate the value of foreign labors. Also this study forecast elements effect on foreign labors productivity in the construction industry. And research what element is more important to improve productivity and what element is more difficult to manage. In the result, this study is expected to prospect effective method of foreign labor's management in the domestic construction industry, so contribute to utilize foreign labors more efficiently.

Korea's population change trend is the aging and feminization as Reduction in mortality, average life extension. and is further increased Reduction of birth rate and aging population. if Our country concluded FTA(Free Trade Agreement) with the United States, Europe and China etc. labor-intensive industries will be the decline. Then, the construction workers' jobs are continually reduced. This is critical to the nation's economic, social and environmental influences due to Shortage of construction workforce and increasing labor costs. Eventually this is a major factor in reduced construction productivity. Therefore, this study is presented as a construction productivity development prospects on the value-added analysis per Labour productivity employee from Construction market trends, industry-specific productivity index, industry trends Employed, age tiered workforce trends, women's workforce trends, labor time trend, foreign workers, workforce trends, analysis of trends in construction contract, awarded by Company Size trends, construction management analysis index.

It becomes easy to acquire operating qualification of remote control tower crane and illegal retrofits is increased, remote control tower crane models are increasingly being used in smaller construction sites. However, as the problems caused by tower crane operators who have shortages of operating experience grow, safety accidents is increasing and worker is exposed to risk of accident. In this study, the cause of the accident was derived by analyzing the cause of the remote control tower crane accident. And then, the significance of accident causes was analyzed by AHP technique. The result of this study is that tower crane operators and construction workers do not comply with work rules.

국내의 산재 사고 사망 비율 중 대부분은 건설업이 차지하고 있으며 사망 원인 중 42.9%는 추락사가 차지하고 있다. 따라서 국내 사고 사망을 예방하기 위해서는 노동자의 생명을 지켜주는 안전 장비의 착용 여부가 중요하다. 본 논문에서는 객체 탐지에 사용되는 YOLO v4와 YOLO v4-TINY 알고리즘과 영상 처리에 사용되는 OpenCV를 이용하여 실시간 영상에서 안전모 미착용 인원을 감지하고 관리자에게 알려주는 시스템을 개발하였다. 이 시스템을 활용하여 건설 현장에서 현장 카메라로 안전모 미착용 인원을 실시간으로 검출하여 경고하므로써 작업자의 안전에 기여할 수 있다.

In Korea, the construction industry has been known to have the highest risk of safety accidents compared to other industries. Therefore, in order to improve safety in the construction industry, several researches have been carried out from the past. This study aims at improving safety of labors in construction site by constructing an effective automatic safety helmet detection system using object detection algorithm based on image data of construction field. Deep learning was conducted using Region-based Fully Convolutional Network (R-FCN) which is one of the object detection algorithms based on Convolutional Neural Network (CNN) with Transfer Learning technique. Learning was conducted with 1089 images including human and safety helmet collected from ImageNet and the mean Average Precision (mAP) of the human and the safety helmet was measured as 0.86 and 0.83, respectively.

Purpose: This study was designed to provide necessary institutional improvements for job security for foreign workers in the domestic construction sector. Method: I analyzed the National Statistical Office and related reports to investigate the status of foreign workers. Based on this, the government came up with measures to improve the system. Results: Based on the current comparative advantage index (RCA) analysis, the technology standard of foreign workers compared to Korean workers was evaluated, and the results were analyzed in order of moldwork, rebar, concrete work, stone work, and waterproof work. Conclusion: A foreign worker's work system was introduced to solve the problem of local Lunar New Year's Day field manpower. To ensure stable implementation of the system, there is a need to improve the operation of the employment permit system at construction sites and limit the size of the construction industry that introduces the employment permit system.

The purpose of this study was to suggest measures to improve safety and health training by analyzing trainees who participated in the training programs. A survey was administered to 226 trainees who participated in and completed the safety and health training programs provided by the Korea Occupational Safety and Health Agency. The study results showed that the level of satisfaction of employers for the training programs was the lowest compared to the middle managers and employees. Moreover, the middle managers' job competencies were increased, and they applied newly acquired knowledge and skills to their jobs. However, there were significant differences between industries. Finally, although all levels of trainee agreed on the effectiveness of safety and health training, the perceptions of employers were lower than those of employees. Based on these study results, several implications to improve the safety and health training were suggested.
