건설업의 안전사고는 과거부터 현재까지 지속적인 증가추이를 보이고 있다. 이러한 건설현장의 안전사고를 미연에 방지하거나 최소화하기 위해서는 현장관리자 및 근로자들의 적극적이고 체계적인 안전관리 활동이 필요하다. 그러나 기존 선행연구들에서는 현재 건설현장의 규모별 안전 조직체계가 어떻게 구성되어 있고, 이들의 안전지식 및 업무수행 수준이 어느 정도인지를 명확히 파악한 연구가 미흡하다. 특히, 이들의 안전지식 공유 및 안전업무 협력체계가 어떠한 형태로 이루어지고 있는지를 분석하고, 이를 시각적으로 표현한 연구는 부재한 실정이다. 이에 본 연구는 국내 건설현장의 일반화된 안전 조직체계를 현장규모별로 도출하고, SNA 기법을 통해 구성원들의 안전지식 및 협력체계를 분석하여 향후 건설현장의 효율적인 안전관리 체계구축을 위한 실무 자료를 제시함을 목적으로 수행되었다. Safety-related accidents are continuously increasing in the construction field. In order to prevent or minimize such accidents, a systematic and active safety activities of on-site managers and workers are required. However, preexisting advance research is lacking on how the safety organization systems are built in construction sites varying in sizes, and how well-trained the related personnel are in safety knowledge and task performances. Especially, a research on the analysis of the formation of their safety knowledge sharing and safety performance cooperation and their visualization is virtually nonexistent. In this regard, this research was conducted with a purpose to study the generalized safety organization method of domestic construction sites, analyze the safety knowledge and cooperation system of the members based on the SNA method and ultimately provide a hands-on data that could be effectively utilized in building an effective safety management system in the future.

In order to seek out methods to reduce safety accidents caused by construction machinery and equipment, this study collects data about safety accidents and draws main risk factors by construction from the data, through SNA. It aimed to suggest safety management points to be used in future construction fields, by analyzing risk index of such factors. The finding can be summarized: First, Backhoe Bucket is the risk factor for crash accidents of average workers in earth works; boring machines-maintenance is the risk factor for fall accidents of construction machinery operators in foundation works; bending machine-reinforcing rod processing is the risk factor for jamming accidents of reinforcing rod engineers in frame works; and mobile crane-hook is the risk factor for crash accidents of average workers in lifting works. Second, works can be arranged in turn, according to the risk index: earth, lifting, frame and foundation works. Risk factors can be also arranged according to the risk index: Backhoe in earth works, pile drivers in foundation works, bending machines in frame works and mobile cranes in lifting works. This study has some limits, in that it only analyzed main machinery/equipment, among various kinds of them, for earth, foundation, frame and temporary works (lifting works) and used data collected over three years. Therefore, it is necessary to conduct an analysis using big data, by collecting additional data about a lot of machinery/equipment in future construction fields.

In the rapidly changing social environment due to the recent development of technology, the importance of all working environments related to the improvement of workers quality of life is increasing due to changes in industrial structure and employment conditions. In particular, employment instability is rapidly increasing due to the long-term economic recession and restructuring, the demographic structure is rapidly changing due to aging population and falling fertility rates, and the gender gap between workers is narrowing as womens social advancement has recently expanded. As the paradigm of the job market changes, friction between labor and management is increasing every year, and a social atmosphere has been created that securing a work-life balance due to the improvement of the working environment is linked to corporate productivity and industrial competitiveness. Workers in the construction industry have been working in poorer working conditions than other industries since the past. In particular, it may be even worse for female construction engineers who have entered the construction industry where a male-oriented culture is established and are working. Therefore, this study analyzes the employment and working conditions of female construction engineers with relatively poor working environments, identifies gender discrimination that may occur in the male-oriented construction industry, and derives problems that are currently occurring for female construction engineers. In addition, it is intended to provide basic data for preparing specific policies in the future by grasping the requirements for improving the employment and working conditions of current female construction engineers.

Construction industries in South Korea have taken the lead in reconstructing the nation in the ruin of war in past 20C and the pain of poverty, played a role in the foundation of economic development and taken the important responsibility for improving economic development of the nation and the quality of life by establishing industry based facilities and national life based facilities for development of techniques. Recently, they also account for a great part of economic growth of the nation as a provider of foreign currency as there are many orders of overseas constructions by overseas expansion. Construction industries are based on such positive images while they are considered as negative images such as rough work, poor construction and 3D jobs. As they have influenced teenagers who decided their careers in construction industries, there are many issues such as the lack of young technical talented people and the evasion of having a career in construction industries. In this study, we examined the actual images of construction industries, found the problems on current improvement activities of images in domestic construction industries and conducted a study to suggest solutions of improving images of domestic construction industries by conducting a survey with vacational high school students and academic high school students in order to attract young talented people.

Manpower issues heavily affect work efficiency and job satisfaction; directly resolving these issues requires establishing improvement measures to address the supply and demand of labor in each industry. The purpose of this study aims to address job satisfaction of female employees working in design offices. Upon analysis, research revealed that overall job satisfaction was at a normal range, although in major categories like personal environment, dissatisfaction levels were high. When examining the degree of dissatisfaction by position, it was discovered that assistant managers experienced the highest level of dissatisfaction followed by the employee section heads. Depending on current job satisfactory levels, many female employees were willing to change jobs or retire early. Particularly, competent female employees in lower-level design positions had the most potential to quit on short notice, undeniably contributing to future manpower issues. After examining the improvement requirements of female employees and reflecting on international benchmarking cases, a proposed plan targeting job satisfaction must first focus on personal environment then on workplace atmosphere and organizational culture. The results of this study can be used as basic data for related research topics; however, detailed analysis is limited due to the lack of various variables related to size, age, and gender. Therefore, a future follow-up study will be conducted to complement this topic of work satisfaction among female employees in current design firms.

This study aims to analyze the perception college students have of the construction industry when determining a career path to become a construction engineer through a newly established image evaluation methodology; urgent improvement measures involving negative depictions were also presented. Upon analysis, the most common negative impressions found among college students in construction related and unrelated majors in Korea entailed sincerity construction, business ethics and the work environment; the results were deemed to be insufficient. The underlying issues involved the uncertainty and lack of accountability concerning image improvement activities targeting university students. When it came to students in non-construction related majors, public relations was inadequate at universities. Through benchmarking analysis, a couple of ways were derived to improve the overall construction industry’s image that encompassed the necessity to first establish experiential and educational programs for college students and prepare promotional materials. This study is limited to college students who are planning to enter the construction industry as future construction technicians. There are limitations in that surveys on various young people currently engaged in the construction industry have not been conducted. In the future, further research is needed on young people already involved in the construction industry by analyzing the main causes of departure of young construction workers. Continuous research will be conducted on improvement measures for effective inflow and efficient maintenance of young and competent construction workers.
