Change in labor time is affecting occupational safety and health. Recently reduction in labor time brought innovational operation method, investment in plant and equipment, and flexible labor time in some companies, thereby affecting working conditions for labourers. However, working conditions for some vulnerable social groups have deteriorated. As a result, they are becoming more exposed to risk factors such as injury and emotional stress. In this study we use 2014 KWCS data in order to find the social and demographic characteristics in Korean working conditions. To this end, we use exploratory data analysis approach to find the relationship between some of the important variables in the KWCS data. We also use Press-State-Response model to find which group of people are vulnerable to Press and State. We find that women, people over age 50 and business owners are more vulnerable to Press and State than men, people below age 50 and wage workers.

As part of a series of studies about improving yellow croaker drift gill net fishing gear and the development of a labor-saving fishing system, we installed a labor-saving-type, five-step-drum net hauler, and a triple-V-type net hauler in 108 Daeheung-ho, a fishing boat which operates drift gill nets for yellow croakers mainly in the sea near Chu-ja Island. Net damage with the labor-saving-type, five-step-drum net hauler is lower than for the triple-V-type net hauler. In addition, there was a reduction in the standard operational crew of two people. The lead time for hauling the labor-saving net was approximately 10% and 19.2% less than for hauling the triple-V-type net hauler and for hauling by hand, respectively. It was found that there were fewer slip in fishing gear and less damage to the wing of the drum as well as less damage to the fish when the labor-saving-type, five-step-drum net hauler was used than when the triple-V-type net hauler was used. In the survey, the lead time for hauling the net was approximately 21.6% and 45.2% more effective than hauling with the triple-V-type net hauler and hauling by hand, respectively. The crew was reduced by approximately 18.2% and 25% than when hauling with the triple-V-type net hauler and hauling by hand, respectively. In addition, cessation of operation and damage to the fish were reduced when compared to the triple-V-type net hauler and hauling by hand.

Purpose: The Korean franchise market has undergone drastic growth in recent years. Followed by expansion of franchise business types, relevant legal matters have diversified. Compared to conventional economic laws that focused on resolving problems related to unfair transactions between franchisors and franchisees, more diverse labor laws have emerged recently due to governance and economic dependencies of franchise structure. However, it was found that the business environment of franchisees and working conditions of franchisee employees have not changed accordingly due to the unique structure of franchise business. Though franchisees are entrepreneurs independent from franchisors, they are still under franchising contract with the franchisors. For instance, employees of franchisees have been exposed to malpractices in regard to pay, time, and other working conditions. These malpractices may show the ineffectiveness of current labor laws. Labor management is an important issue for sustainability of franchise businesses. Negative publicity of franchises generated from violating relevant labor laws may have significant negative impact on overall image of franchised brands. However, franchisors should not hold franchisees fully responsible for legal violations in terms of labor management but strive to prevent relevant risks. Thus, the recent amendment in labor law related to increased minimum wage and reduced worktime have called for more attention to effectively implementing the law. Research design, data, and methodology: This study was conducted through a review of franchise-related laws and various institutions and policies. Results: It is further needed for all parties, including franchisors, franchisees, and franchisee employees, to take collaborative actions to improve working conditions of franchisees. Therefore, this study aims to propose appropriate and effective response plans toward recent changes in the Minimum Wage Act, while strengthening sustainability of franchisors, franchisees, and their employees. Conclusions: The proposal mainly contains plans regarding profit-related aids and profit sharing/cost reduction strategies for franchisees, as well as collective bargaining in the franchisor-franchisee relation. More detailed suggestions are included. Conclusions: This proposal may help franchisors and policymakers develop business plans and policies in improving business conditions of franchisees and working conditions of franchisee employees.

Fresh-cut foods have been widely used in the school foodservice industry due to their convenience and saving effects of labor and working hours. This study evaluated the effectiveness of using fresh-cut foods in school foodservice with respect to cost efficiency, customer satisfaction, employee satisfaction, and productivity. First, in terms of cost efficiency, the cost of the fresh-cut food per meal price significantly increased by 2.6% via the new production plan. Meanwhile, the costs of labor and food wastes significantly decreased by 3.0% and 0.3%, respectively, after implementing the new plan. Second, customer satisfaction towards foodservice significantly increased, from 2.94 points prior to the new plan to 3.45 points. Third, foodservice productivity such as of the number of meals per full-time equivalent employee increased by 5.7 meals, from 143.0 meals to 148.7 meals after intervention. The productivity index of work hours for producing a meal also increased and was reflected by a work time reduction of 0.77 minutes, specifically from 4.25 minutes to 3.48 minutes. The labor cost per meal also decreased by 29.9 won, from 331.91 won to 301.97 won, but there was no significant difference. Through these results, we identified that using pre-process foods in school foodservice has positive effects on labor saving, customer satisfaction, and employee work satisfaction.

본 연구는 1995년부터 2017년까지의 16개 지방자치단체 지역별 패널통계를 활용하여 노동력 고령화가 노동 생산성에 미치는 영향을 분석하였다. 지역별 고정효과와 다양한 조정변수들을 고려한 패널회귀분석 결과에서 총취업자 중 60세 이상의 취업자 비중으로 정의한 노동력 고령화는 노동 생산성에 매우 일관되고 유의한 음(-)의 효과를 주며, 부정적인 효과의 크기는 노동력 고령화가 1% 증가할 때마다 노동 생산성이 약 0.14 ~ 0.20% 감소하는 것으로 나타났다. 이밖에 조정변수로 고려된 1인당 자본스톡과 인적자본은 노동 생산성이 증가하는데 많은 기여를 하고, 경기변동의 대리변수인 실업률은 예상과 같이 노동 생산성에 유의한 음(-)의 효과를 미치며, 비록 유의하지는 않지만, 전체 산업 중 서비스업의 비중을 의미하는 산업구조의 계수가 양(+)의 값을 보이지만 유의하지 않은 것으로 확인되었다. 본 연구의 결과를 통해 노동력 고령화로 예상되는 노동 생산성의 감소를 억제하기 위해 인적자본을 유지 및 확충할 수 있는 경제 및 교육정책의 설계와 구축이 필요하다는 시사점을 도출할 수 있다.

이 글은 여성의 경제활동 참여 증가를 통해 근대적 성별분업이 도전받고 있음에도 불구하고 가족 내 성 평등이 지체되는 현실에 주목하고, 한국, 일본, 대만 등 동아시아 3개국 여성들의 성 평등의식과 현실 간의 불일치를 분석하고자 하였다. 이에 EASS 자료를 바탕으로 동아시아 여성들의 연령, 교육기간, 가구소득, 성별분업에 대한 태도, 부부 각각의 노동시간, 가족지원망이 가사분담에 미치는 영향력의 차이를 분석하고, 각 국가별 특성을 살피고자 하였다. 분석 결과 한국과 대만은 성별분업에 대한 보수적 성향에도 불구하고 남성들의 실질적 가사부담률이 높게 나타났으며, 반면 일본의 경우 여성들의 진보적 태도에도 불구하고 실제 가사부담률이 높게 나타났다. 이러한 차이는 대만, 한국과 일본 여성들의 평균 노동시간에 기인하는데, 한국과 대만 여성들의 경우 전일제 노동에 종사하는 경우가 많아 상대적으로 가사 노동시간을 줄이는데 영향을 미치는 것으로 판단되었다. 또한 대만은 가족 특성이, 한국은 여성경제활동의 성격이 가사부담률에 영향을 미치고 있었다. 3세대 동거가구의 비율이 높은 대만은 부모로부터의 돌봄 지원이 가사 부담을 줄이는데 기여하며, 한국에서는 여성의 교육기간이 길수록 가사부담률이 증가하는 경향을 보임으로써 고학력 여성의 상대적으로 낮은 경제활동 참여가 가사노동에서의 협상력 약화에 영향을 미치고 있음을 알 수 있었다. 이 글에서는 가사분담에 영향을 미치는 요인으로서 개인적 요인뿐 아니라 노동시장 성격이나 구조, 가족 형태 등 제도적 요인이 영향을 미치고 있음을 확인함으로써, 향후 성별분업 연구에서 개인과 부부의 특성뿐 아니라 거시적 요인에 대한 요인 분석이 필요함을 제안하였다.

PURPOSES : Most of the traffic surveys are carried out by an inspection method by the manpower. In some cases, the video equipment is used only in some regions when the traffic volume is surveyed. In this case, there is environmental restriction that the road equipment to fix the video equipment should exist. Also, in areas where information such as digital maps and satellite photographs is old or not provided, they are forced to rely on manpower research, but it is difficult to put huge amounts of time and money into the research in places where labor supply and demand is difficult. This difficulty is particularly pronounced in overseas business. METHODS : The purpose of this study is to improve the efficiency of business by using the drones in the traffic investigation through analysis of the cost reduction effect between the existing method and the proposed method in the overseas business traffic survey. The scope of the research is limited to the scope of research, and based on the case of overseas projects, the method of using drone for each research sector is suggested. RESULTS : In the traffic condition survey section, we propose the use of drone for traffic survey and queue length survey, and it is confirmed that there is a cost saving effect of 16% ~ 27% compared with the existing method. In the road condition survey, we propose the use of drones for road surface linear survey, geometry survey, and obstacle survey, and it was confirmed that the cost reduction effect is 39% ~ 93% compared to the existing method. CONCLUSIONS : In addition to overseas business, it is expected that it will have a positive effect on research time and cost reduction by using drone in traffic survey in domestic area where labor supply is not easy or basic data is insufficient.
