In Japan, the population progresses to the extreme aging society and it is entering the phase of the population decrease while the population increase is continuing in the world. The construction market is expected to shrink accordingly, however the situation of labor shortage is expected to continue at a faster rate, because the aging of construction workers is progressing and new younger labor force cannot be secured. In order to supplement the labor shortage, it is required to progress mechanization, automation, labor saving, and efficiency improvement by utilizing the information well in each stage in a series of flow of planning, design, construction, operation, and disassembly in one building. The measures to maintain and expand the construction market by the new efficiency improvement techniques which enhance the utilization degree of building information are required. Currently, the elemental technologies which utilized BIM (Building Information Modeling) are accumulated by advancing digitization in each phase. DX (Digital transformation) in the construction industry can be achieved by the technology maturing and having a series of continuities. It is anticipated that this will evolve to a new method which is unprecedented. Present status of BIM and mechanized constructions in Taisei Construction are introduced, and future prospect is described.

Purpose - The purpose of this study was to examine the mediating effect of employee competence on the relationship between the utilization of non-regular workers and firm performance. Design/methodology/approach - This study utilized 427 firm level data from HCCP. The Exploratory Factor Analysis (EFA) and the multiple regression analysis were conducted to verify the hypotheses. Findings - We found that the utilization of non-regular workers is not significantly related to firm performance. However, the utilization of non-regular workers had a negative relationship with employee competence, and that employee competence mediated the relationship between the utilization of non-regular workers and firm performance. Research implications or Originality - As environmental uncertainty and competition between firms intensify, more and more firms are utilizing non-regular workers. Research on the relationship between the utilization of non-regular workers and firm performance is continuously conducted, but research on the process of explaining the specific relationship between them is still insufficient. Our study contributes the related research area by identifying the mediating role of employee competence on the utilization of non-regular workers and firm performance relationship.

It is frequently pointed out that the Korean economy, with its scarce natural resources, would never have been able to achieve current levels of economic development without the massive provision of well-educated, hardworking human resources. Throughout the industrialization process ,full-fledged deployment and mobilization of qualified human resources have been the foundation to industrial policy and S&T policy. This paper describes the development of S&T human resources in Korea using various statistics including educational enrollment rates, unemployment rates, the allocation of researchers and R&D expenditures among sectors of performance, educational composition of employment within and across industries, technical human resource shortage rates, relative wage levels of SMEs, and composition of labor force by age-group and gender. While analyzing S&T human resources development, this paper discusses issues such as the mismatched demand and supply of skill and knowledge levels of the highly educated, the unbalanced distribution of S&T human resources between sectors, and the low utilization of the female and aged labor force. This paper suggests that the policy maker applies a hybrid of quantitative and qualitative policies to reduce the mismatches of supply and demand of skill and knowledge levels for each labor market categorized according to supply side.

The purpose of this study was to investigate the contexts in which employed mothers with young children consider leaving the labor force. We used a mixed methods design, which integrates the findings of quantitative and qualitative analyses, to better understand the dynamics underlying employed mothers' intentions to leave the labor force. The participants of both quantitative (N = 324) and qualitative (N = 16) data were married mothers who were employed full-time and had at least one child younger than elementary-school age at the time of data collection. Both the quantitative analysis of logistic regression and the qualitative thematic analysis revealed that the child's age, the husband's income, the utilization of child care by relatives, the mother's job involvement, family-to-work role conflict, and other costs and rewards of participation in the work force were the important contexts where employed mothers considered leaving the labor force. The quantitative analysis uniquely found that being employed at a workplace with flexible work hours were associated with lower odds of considering exit from the labor market. The qualitative analysis highlighted that the decision to leave the labor force or to stay in it is a complicated issue that almost all employed mothers potentially face at some point in their careers. These findings suggest that policy support is warranted to help employed mothers with young children remain in the workforce when they wish to.

In the construction industry, a great deal of research has been focused on productivity improvement because a minor change in labor productivity can often make the difference between a profit and a loss. This study shows how productivity measurement methods can be applied in practice, step by step, to analyze and identify potential problems both in productivity and methods performance for masonry work. A work sampling technique was conducted to determine the nature and extent of an observable activity as an aid to measuring overall performance. Also, a method productivity delay model was used to identify non-productivity in individual cycle times. From the work sampling technique, it was found that the masonry crew had a Labor Utilization Factor of 47.1%, and from the videotape analysis, it was found that the material and dumpster location need to be adjusted to reduce the travelling distance. We have found that efforts to improve the productivity of masonry work should be focused almost exclusively on machine and labor delays, based on the result from the method productivity delay model.

Objectives: The present system of occupational safety and health law gives priority to traditional command and control regulations. However, this may give rise to problems such as the delay of standard-setting and shortages of human resources. The aim of this study is to examine the usability of private standards in occupational safety and health systems. Materials: After the limits of occupational safety and health law were examined, an application plan for private norms (EN, as enforced in the EU) and occupational safety and health management systems (OSHMS) was investigated. Results: The utilization of private norms and OSHMS may address the limits of the current legal system. In particular, OSHMS is known internationally as a measure for achieving improvements in overall occupational safety and health performance. As a result, occupational safety and health law and private norms/OSHMS are complementary to one another. Conclusions: Even though the utilization of private standards may give rise to legal questions, such standards as complementary measures to traditional command and control regulations need to be utilized progressively in occupational safety and health systems.

한국 노동시장에서 고학력 여성의 낮은 취업률은 고급 여성인력의 낭비라는 비판과 함께 사회적 문제로 지적되어 왔다. 교육과 관련된 한국여성의 경제행위는 기존 미시경제학의 분석틀로 설명하기 어려운 현상이다. 외견상 모순되어 보이는 한국여성의 노동참여 유형을 설명하기 위해서 거시적 측면의 여러 요인들을 검토했다. 선진국의 경우 교육과 여성노동 참여는 명백히 정(正)의 관계로 나타나는 데 반해서 개도국의 경우는 그 둘간의 관계가 다양하다. 이러한 다양성에도 불구하고 이들 개도국에서 공통적으로 발견되는 점은 고학력 여성들은 저학력 여성들에 비해 훨씬 더 적극적으로 노동시장에 참여하고 있다는 것이다. 이에 반해서 한국의 경우는 선진국이나 개도국 어느 유형에도 속하지 않는 특이한 경우이다. 여성의 노동시장 참여에 대한 교육효과는 다른 나라와 비교하여 아주 미약하며, 특히 두드러진 점은 고학력 여성들의 노동시장 참여율이 아주 낮다는 것이다. 거시적 수준에서 여성집단의 교육수준 향상이나 여성의 사회활동에 대한 부정적 인식의 변화가 여성의 교육 수준 향상이나 여성의 사회활동에 대한 부정적 인식의 변화가 여성의 경제활동에 중요한 영향을 미친다는 기존의 연구가 있었다. 필자는 몇 가지 사례를 제시하면서 이 두 요인이 고학력 여성의 노동시장 참여를 유도해 내는 데에 아주 중요한 요인이라는 기존의 논의를 반박하면서, 여성노동에 대한 수요의 급증이 그 어느 요인보다도 중요한 것이라고 주장한다. 여성노동시장 참여에 대한 교육효과가 낮은 이유는 노동시장에서 기혼여성에 대한 차별로 많이 설명될 수 있다. 기혼여성에 대한 차별은 화이트칼라직에서 더 체계적으로 나타난다. 이러한 직종은 교육수준이 상대적으로 높은 여성들을 위한 것이어서 고학력 여성의 취업의 기회를 제한한다. 선진국의 과거에도 노동시장에서 기혼여성에 대한 차별은 존재했다. 그러나 산업발전과 더불어 증가한 비육체노동직은 여성노동력에 대한 수요를 증가시켰으며 특히 그 중 고학력 여성의 노동수요 증가가 두드러졌다. 요약하면, 한국의 경우 풍부한 고학력 남성노동력의 공급과 비육체노동직에서 여성노동에 대한 수요의 완만한 증가로 여성노동참여에 관한 교육의 효과는 미미할 수 밖에 없다.

건설공사에 있어 노무량은 건설공사비 산정을 위한 기준으로 사용되고 있고, 건설산업의 생산성을 파악하는 근거자료로도 활용되고 있다. 하지만 노무량의 기준이라고 하는 표준품셈과 실제투입 노무량과 큰 차이를 보이고 있어 이를 해결할 수 있는 방안이 필요하다. 따라서 본 연구에서는 실제투입 노무량을 좀 더 정확하고 간편하게 입력할 수 있는 시스템을 구축하기 위하여 전통적인 종이와 펜을 이용한 수기방식을 그대로 따르면서 전자문서화에 대한 이중부담이 없는 디지털펜을 이용하는 방안을 제시하고자 한다. 본 연구를 통해 실투입 작업정보를 단순히 저장하는 것뿐만 아니라 웹을 통한 공유 및 활용을 통해서 공사비 산정업무의 생산성 측면에서도 기여할 것으로 사료된다.

Purpose - Based on previous studies, this study extends current research and investigates whether the sub-factors of emotional intelligence increase job satisfaction or employee intrinsic and extrinsic motivation and perceived organizational support. Research design, data, and methodology - This study categorizes service employees' (consultants) emotional intelligence into four sub-factors: regulation of emotion, appraisal of emotion, utilization of emotion, and expression of emotion. The study then investigates the sub-factor effects on job satisfaction. A total of 353 valid questionnaires were collected. Results - The results of the path analysis showed that appraisal, utilization, and expression of emotion had a positive effect on intrinsic motivation, and utilization of emotion had a positive effect on extrinsic motivation. Extrinsic motivation had a positive effect on perceived organizational support and job satisfaction, and perceived organizational support had a positive effect on job satisfaction. Conclusion - As consultants' utilization of emotion is rendered as the ability to use emotion to improve performance, the conclusion is that such factors as monetary performance incentives are important in order to boost job satisfaction of the consultants.
