In this study, with the data of Human Capital Corporate Panel(HCCP) we find that the explaining power of the new hiring rate of experienced regular workers is very strong and statistically significant as a main causal factor to the decreasing trend of investment on education and training for workers in corporates, which means a sign of weakening of the internal labor market. Possibility of wage penalty from switching jobs has been weakened considerably too. The effective alternative policy measures to the weakening or laxity of the internal labor markets and whereby followed reduction in investment on education and training for workers in corporates are construction of social system outside of individual corporates to upbring field-tailored manpower of high quality for young generations and small and medium sized enterprises.

석탄산업은 서민생활보호와 에너지 안보 등 국가정책 목표달성을 위하여 매우 중요한 역할을 하고 있다. 또한 태백지역의 경우에는 석탄산업의 존립이 지역사회의 생존과 직결되고 있어서 이의 활성화가 매우 긴요하다. 그러나 석탄산업은 작업환경이 나쁘고 임금수준 등의 제반 여건이 좋지 않고, 사양산업이라는 인식이 만연되어 있는 관계로 근로자들의 이직율이 높고 신규인력의 유입율도 낮아서 탄광의 운영에 커다란 애로요인으로 등장하고 있다. 본 연구는 이러한 상황에 직면해 있는 태백지역 탄광업체의 인력난을 해결해 보기 위하여 탄광근로자들을 대상으로 설문지를 배포하고 이를 분석하여 그 해결책을 모색해 보고자 했다. 이를 위해서 경로분석과 이원분산분석을 통해서 이직요인을 발견하고 이를 위한 다각적인 대응방안을 구상해 보았다. 연구결과 태백지역 인력난을 완화시키고 노동인력의 정착성을 제고시키기 위해서는 1) 기업내적(企業內的)인 방안(方案)으로 근로생활의 보람(quality of working life) 조성, 기업문화의 조성, 임금제도의 개선과 생산성 향상, 후생복지시설의 개선, 내부적 제도의 개선과 회사운영의 공개, 대외적 홍보, 2) 정부(政府)의 지원방안(支援方案)과 논의사항(論議事項)으로 석탄산업에 대한 재정적 지원, 소비성 서비스업에 대한 노동력 유출억제, 교육여건의 개선 그리고 해외광원수입에 관한 문제는 장애요인이 많으므로 가능한 신중한 검토가 수반되어야 한다는 것 등을 고려할 수 있을 것으로 사료된다.

This study examines the effects of the "youth unemployment bonus" program implemented in 2004. We view this program through the lenz of search-matching models and apply a quasi-experimental approach to an administrative unemployment insurance database of Korea. This episode is particularly useful because the program aims at long-term unemployed youths and the size of public assistance is large enough to subsidize employers for a year with a monthly subsidy of about $600. The main effects are found to be as follows: (i) the search period gets shortened by 18 days, (ii) the subsequent wage has increased by about three percents, and (iii) a conservative benefit-cost analysis reveals the validity of this program. We interpret these results in the context of general equilibrium models.

This paper has suggested the necessity of introducing training contents using XR(Extended reality) technology as a way to lower the high rate of nursing accidents among unskilled technical personnel in domestic shipbuilding industry, focusing on cable pulling using winch. The occurrence rate of nursing accidents in the domestic shipbuilding industry was almost double(197.4%) (2017~2020) when compared with other manufacturing industries. In particular, it is worth noting that more than 31.8% of nursing accidents in the shipbuilding industry occurred among workers whose job experience is no more than 6 months. Most of new workers are seen to have hard time due to several factors such as lack of work information, inexperience, and unfamiliarity with the working environments. This indicates that it is essential to incorporate more effective training method that could help new workers become familiar with technical skills as well as working environments in a short period of time. Currently, education/training at the domestic shipyard is biased toward technical skills such as welding, painting, machine installation, and electrical installation. Contrary, even more important training required to get new workers used to the working environment has remained at a superficial level such as explaining ship building processes using 2D drawings. This may be the reason why it is inevitable to repeat similar training at OJT (On-the-Job Training) even at the leading domestic companies. Domestic shipbuilding industries have been attracting a lot of new workers thanks to recent economic recovery, which is very likely to increase the occurrence of disasters. In this paper, the introduction of training using XR technology was proposed, and as a specific example, the process of pulling cables using winches on ships was implemented as XR-based training content by using Unity. Using the developed content, it demonstrated that new workers can experience the actual work process in advance through simulation in a virtual space, thereby becoming more effective training content that can help new workers become familiar with the work environment.

SMEs in Korea are suffering from severe manpower shortage due to poor incentive system and employees' frequent change of jobs. So far, the government has made continuous efforts to solve these problems, but SMEs still have the same problem. It is critical for SMEs to maintain core employees for long term who can directly contribute to the business performance. However, Korean manpower policies for SMEs has mainly focused on hiring new recruits and attracting experienced high caliber employees to SMEs. Relatively, policies for attracting in-house employees to work for longer term were insufficient. This paper focuses on providing strategic policy options to make core employees stay in the company for longer term. For this, it identifies the concept and features of core employees and reviews the necessity of introducing the Mutual Aid Project. Also, it suggests the way to enhance the effectiveness of policy by analyzing current Mutual Aid Fund programs in Korea.

The construction industry is a labor-oriented and quality, cost, and schedule performance is effected by technicians. However, the construction industry have faced a labor shortage problem. Therefore, technician graying and no new workers inflow cause labor shortage and decline of worker's skill level. The utilization of foreign technicians instead of domestic technicians has been increased in the construction industry. This paper performed questionnaire survey for 43 managers on 14 project fields to determine the current status and problems of construction technicians and to propose a improvement plan. As a result, most foreign technicians are carpenters and iron workers, but the skill levels are generally lower than domestics. The major problems for foreign technicians are communication and non-skilled. Then, labor productivity and accident rates of foreign technicians are higher than domestics. This paper proposes that skill training programs, language lessons, and multi-cultural programs are effective to improve foreign workers' problems.

It is a very difficult task to establish a collaborative procedure in a new business that requires multilateral collaboration or to revise the regulation by analyzing and proving objectively the problems in the collaborative process conducted already by multilateral collaboration. In this paper, we proposed an optimization model for collaborative process to establish the operation procedure between collaborative parties using PERT/CPM network diagram which allows us to calculate the processing time. In order to verify the effectiveness and usefulness of our model for the collaboration process optimization developed in this study, we applied the developed collaborative procedure to student selection of the work-and-study-in-parallel course associated with a degree executed by Ministry of Employment and Labor. This study can be useful not only for newly establishing or reconfiguring collaborative procedures but also for standardizing the business procedures for building information systems between collaborative organizations.

The Korean market of pension plans has recently increased and pension plans will be expected to play an important role in the retirement system as complement of the national pension system in the future. However, there are a few of research papers on actuarial projections of pension plans. This paper will discuss a long-term financial projection on defined pension plans using data based on the national pension workplace participants. Previous researches focused on company-based financial projection of pension plan. But, this paper concerns on total Korean pension participants and suggests a method to calculate future financial projection of total pension plans. Finally, this research will suggest several numerical results of normal costs, benefits, numbers of workers, etc.

Some problems, such as aging workers, a decreased population due to a low birth rate, and shortage of skilled workers, are rising in construction sites. Therefore research for smart construction technology that can be improved for productivity, safety, and quality has been recently developed with government support by replacing traditional construction technology with advanced digital technology. In particular, the motor grader that mainly performs road surface flattening is a construction machine that requires the application of automation technology for repetitive construction. It is predicted that the construction period will be shortened if the construction automation technology such as trajectory tracking, automation work, and remote control technology is applied. In this study, we introduce the hardware and software architecture of the smart motor grader to apply unmanned and automation technology and then analyze the traditional earthwork method of the motor grader. We suggested the application plans for the path pattern and blade control method of the smart motor grader based on this. In addition, we verified the performance of waypoint-based path-following depending on scenarios and the blade control's performance through tests.

Dangerous tasks that occur every day at industrial site manufacturing plants, which have recently been making rapid changes, were classified by type, and the effect of mobile circuit television (CCTV) on safety accidents among daily safety management methods was analyzed. The subject of the study is about 3,000 workers who manage the infrastructure facility sector to supply utilities such as gas, water, and electricity to the display manufacturing process located in Asan City, and the study was conducted based on the daily dangerous work from 2019 to 2022, and during this study period, many construction works such as new investment and expansion of construction and manufacturing processes were occurring at the site. As a result, the rate of safety accidents and exposure to risks are expanding, and most of the safety accidents occurred because the sectors that did not follow the basics and the safety measures on the site were not implemented. In this paper, it was confirmed that there is an accident reduction effect according to the relationship between the dangerous work classified according to the work importance and the mobile CCTV shooting rate. Considering the characteristics of the manufacturing plant site, it can be used to play the role of basic data for preventing safety accidents based on the expansion of the introduction of a new safety management culture in the future.
