This study comparatively analyzed the differences in the talented human resources perceived by enterprises and job seekers in terms of recruitment trends of companies related to the 4th Industrial Revolution, focusing on 16 factors. The analysis data was collected from enterprises and job seekers related to the 4th Industrial Revolution, and the analysis method was applied to a convergence research methodology that mixes social network analysis and variance analysis using big data type. As a result, several things were verified. First, large enterprises emphasized communication, and small enterprises emphasized competency and confidence. Second, in the manufacturing industry, enterprises emphasized confidence and competence, and job seekers emphasized spec and passion. Third, in the service industry, enterprises emphasized personality and competence, and job seekers emphasized spec and global. Fourth, there was a big difference in talented human resources between enterprises and job seekers according to manufacturing and service industries. Based on these results, we discussed the opening of employment information for enterprises to reduce the recognition mismatch in the talented human resources.

Objective: This study aims to investigate the impact of changes in working conditions on job-related stress and musculoskeletal disorders using the results of seven surveys conducted at a single workplace from 2004 to 2022 regarding factors hazardous to the musculoskeletal system. Additionally, the study aims to propose alternative methods of investigating factors hazardous to the musculoskeletal system. Methods: A car parts manufacturing plant where the same survey was taken seven times from 2004 to 2022 was selected and the survey data was analyzed. The main contents of the survey were weekly working hours, Borg's scale, work intensity, job-related stress, and the prevalence of musculoskeletal symptoms. The statistical analysis was performed using SAS (version 9.4). Results: The results of this study are as follows. Firstly, changes in working conditions have an impact on job-related stress. Secondly, changes in working conditions have an impact on work intensity indicators. Thirdly, changes in working conditions have an impact on the prevalence of musculoskeletal symptoms. Fourthly, even with an increase in age and length of service, job-related stress and musculoskeletal symptoms were alleviated when working conditions were improved. Conclusions: In order for measures to reduce musculoskeletal disorders to be successful, working conditions must not deteriorate, and it is necessary to demand revisions to regulations, etc. to reflect these points in the investigation of hazardous factors to the musculoskeletal system.

Recently, global competition in the manufacturing sector is driving firms in the manufacturing sector to conduct product innovation projects to maintain their competitive edge. The key points of product innovation projects are 1) what the purpose of the project is and 2) what expected results in the target market can be achieved by implementing the innovation. Therefore, this study focuses on the performance of innovation projects with a business viewpoint. In this respect, this study proposes the "achievement rate" of product innovation projects as a measurement of project performance. Then, this study finds the best strategies from various innovation activities to optimize the achievement rate of product innovation projects. There are three major innovation activities for the projects, including three types of R&D activities: Internal, joint and external R&D, and five types of non-R&D activities - acquisition of machines, equipment and software, purchasing external knowledge, job education and training, market research and design. This study applies decision tree modeling, a kind of data-mining methodology, to explore effective innovation activities. This study employs the data from the 'Korean Innovation Survey (KIS) 2014: Manufacturing Sector.' The KIS 2014 gathered information about innovation activities in the manufacturing sector over three years (2011-2013). This study gives some practical implication for managing the activities. First, innovation activities that increased the achievement rate of product diversification projects included a combination of market research, new product design, and job training. Second, our results show that a combination of internal R&D, job training and training, and market research increases the project achievement most for the replacement of outdated products. Third, new market creation or extension of market share indicates that launching replacement products and continuously upgrading products are most important.

Analysis of risky behavior factors for workers in the manufacturing industry enables effective human error prevention and systemization of an efficient safety management system. This study examines the relationship between the effects of workers' work psychology, work environment, and work deviation factors on risky behavior intentions and the effects of such risky behavior intentions on risky behaviors. Among the small and medium-sized manufacturing industries, the analysis was focused on a survey of 80 workers in the manufacturing and processing industry. Looking at the results, it was found that work psychology and work deviation had an effect on the intention of risky behavior, but the work environment factors corresponding to job satisfaction and workload did not affect the intention of risky behavior. The relationship with colleagues, the degree of satisfaction or dissatisfaction with the job, the degree of importance of the job that the worker feels, and the tightness of time to digest a large amount of work do not affect intentionally inducing dangerous work, but they do affect risky behavior. In the absence of intention, the work environment factor was found to accompany dangerous behavior.

This paper examines the effect of the market power of firms in the product market on job creation, job destruction and net job growth. It uses the reconstructed establishment data in the Korean Annual Mining and Manufacturing Survey between 1982 and 2002. This paper shows that job creation has continuously declined since the late 1980s and the decline is common for both market-dominant and competitive firms. The effect of market dominance on job creation is negative, controlling the firm-characteristics variables such as firm size and firm age.

Purpose: In Korea, the number of migrant workers is increasing. However, migrant workers have low job satisfaction due to poor working environment, and insufficient social support. This study aimed to investigate the role of social support for job satisfaction of migrant workers. Method: We have analyzed the survey data of 397 migrant workers collected from free clinic for migrant workers located in Seoul, Gyeonggi-do and Chungcheong-do. Result: When the migrant workers received monetary and emotional supports from supervisors and colleagues, their job satisfaction turned out to be significantly high. The factors that influence job satisfaction of migrant workers are as follows: involvement in manufacturing industry, over 9 hours of daily sleep, monetary and emotional support from supervisors. Their job satisfaction strongly influenced by these factors. Conclusion: Social support will increase job satisfaction of migrant workers and it will subsequently decrease job turnover rate and increase productivity as well as quality of life.

The purpose of this study was to define the relationship between job stress contents and smoking habits of manufacturing male workers. The 872 male workers were observed the general characteristics, smoking habits and job stress contents from the JCQ, during the period from February 1st to April 30st, 2012, using the self-administered questionnaires. As a results, the smoking rate of study subjects was 53.0%, and in terms of smoking status by general characteristics, the smoking group was higher in the group of age, job position and job career than their respective counterparts. In terms of smoking status by job stress contents, the smoking group was higher in the group of job demand and supervisor support than their respective counterparts. Based on the results of logistic regression adjusted age, job position and job career, the odds ratio of smoking was significantly increase in the high group of job demand than that of low group, but it was significantly decrease in the low group of supervisor support than that of high group. Above results suggested that the smoking related with the job demand and the supervisor support among the job stress contents.

This paper proposes a new AGV dispatching algorithm which is suitable for heterarchical manufacturing control structure. It is developed on the basis of bidding concept utilizing the information of work-in-process in incoming and outgoing buffers of workstation, and travel time of AGV. Since the bidding functions are functions of two parameters, sensitivity test is performed to find their appropriate values. The performance of the algorithm is compared with those of well-known existing rules in terms of system throughput through simulation on a hypothetical job shop type manufacturing system.

The job shop scheduling problem has been a major target for many researchers. And, most of the past studies did not consider setup time. In many cases of real manufacturing environment, however, there exists a setup time for each operations. The setup can be divide into two parts, one can be done after job arrival. The setup time based on the latter can be summed together with processing time, but that based on the former can not be. We propose an approximation method based on shifting bottleneck procedure for solving the job shop scheduling problem with sequence independent setup time. It schedules the machines one by one, taking a bottleneck machine among the machines not yet scheduled. Every time after a new machine is scheduled, all schedules previously established are updated. Both the bottlenck search and the schedule updating procedure are based on solving a single machine scheduling problem with ready time, setup time and delivery time iteratively.
