The purpose of this study were to analyze work function and labor productivity in school foodservice systems through work sampling methodology. Conventional foodservice were classified into 5 group depending on the number of meals served. Commissary school foodservices were also classified into 5 group by cluster analysis using the number of meals served, the number of satellite schools, and the duration of time for delivery of food. Work measurement through work sampling methodology was conducted in at 5 conventional and 21 commissary food -services during 3 consecutive days from September to October in 1995. Results from work measurement through work sampling methodology were as followed : The most prevalent work functions was cleaning (26.5%) and then processing (25.1%) in conventional while it was processing (30.9%) and then cleaning(25.2%) in commissary school foodservice. Delay was 22.9% and 19.7% respectively. Mean labor minutes per meal of conventional and commissary foodservics were 4.57 and 4.09 minutes, respectively : no significant difference in labor minutes per meal existed between the two systems. but mean labor minutes per meal of commissary foodsevices(1.79min) was significantly lower than that of conventional foodservice(2.33min) during work time before service (p<0.05). Productivity was significantly lower in foodservices which served less than 400 servings ; n significant differences existed among 401-70, 701-1,100 and 1,101-1,500 meals. The highest productivity was in conventional school foodservices which served 1,501-1,900meals. Labor minutes per meal of commissary school foodservice which served less than 400meals per day was significantly lower than those of foodservice which served 401-1,900meals (p<0.05). Labor minutes per meal, preparation and cleaning were positively correlation in two school foodservice systems.

The productivity of a hospital foodservice system has a significant implication in hospital management as costs for labor and material increase, competitions among hospitals increase, and patients' expectations as to the quality of hospital services increase. The foodservice is characterized by its labor intensiveness. The objective of this study was to examine associations between operational and managerial factors and the productivity of dishwashing work in hospital foodservice systems. The labor productivity in 20 conventional food service systems was assessed and related to a number of influencing variables within the system. The productivity measurement was based upon the total dish equivalents as a ratio of the total direct and non-direct labor hours required to wash these dishes. 20 hospitals with more than 500 beds located in Seoul were surveyed to obtain data for study variables. Questionnaire and a survey form were mailed. Statistical methods used in this study were descriptive analysis and Pearson product moment correlation analysis. Hospital system characteristic which was found to correlate significantly with productivity was the ratio of dish loss. As this increased, the productivity level increased.

본고는 생산현장에서의 인적자본 축적, 즉 근로자의 숙련형성에 영향을 주는 요인들을 실증적으로 찾아보고, 형성된 숙련이 생산성 향상에 기여하고 있는 것을 확인한다. 먼저 숙련형성의 유형은 '단순/견습근로자 < 단능근로자 < 다능근로자'의 직렬적 순서이다. 제품수요의 급변성과 비정상적인 상황 발생이라는 외부적 내부적 불확실성이 클수록 다능화가 활발하게 이루어지고 있으며, 선배 동료 근로자와의 상호학습, 근로자의 의사결정 참여, 직무 순환 등의 인적자원관리 관행들도 다능화를 촉진한다. 이러한 발견들로부터 생산 현장에서의 숙련형성은 다능화로 대표될 수 있다고 판단된다. 기업의 노동생산성 성장률을 기업의 성장률이라고 하면, 불확실성과 인적자원관리 관행들은 다능화를 통해서 기업의 성장에 영향을 준다. 구체적으로 기업의 다능화 비율이 0.1만큼 올라감에 따라 노동생산성 성장률이 0.019만큼 증가한다. 이것은 또한 다능화가 인적자원관리 관행들에 영향을 받아 형성되는 인적자본 축적의 한 결과라는 주장에 대한 근거가 될 수 있다.

Purpose: The purpose of this study is to investigate how much continuous investment in human capital contributes to increasing labor productivity at not only individual companies but also at the national level, and causes fundamental as well as increases for labor-management conflicts. The current research aimed to empirically demonstrate the importance of human capital investment and furthermore, based on the effect of human resource investment on labor productivity, also re-examine the role of the Labor Commission as well. Research design, data, and methodology: This study was conducted by the Korea Information Service-Financial Accounting System (KIS-FAS) using representative panel data operated by countries to measure whether long-term investment in corporate human resources affects labor productivity. Results: Two distinctive summarized results of the analysis in the Korea Credit Ratings data showed that there was a high positive correlation between corporate human resource investment and economic performance for a ten-year period from 2009 to 2018. Conclusions: The present study concluded that the role of the labor committee should be effectively formed by the labor as a mediation agency and that the role of the mediation committee members should focus more on how to strengthen the human resources management of the union.

The productivity and 13 influencing variables in 14 conventional hospital foodservice systems the total direct and non-direct labor hours required to produce and serve the total number of patient meals plus the number of cafeteria meals. Human resource variable significantly influencing the productivity level was the labor cost. As this index decreased, the meals served per human hour worked increased. System resource variables correlating significantly with productivity were the length of cycle menu, the ratio of staff meals, and modified patient meal ratio. As the length of cycle menu and the ratio of modified patient meal decreased, more meals were produced per human hour. However, as staff meal ratio increased, the meals served per human hour worked increased. The stepwise regression analysis suggests that around 53% of the variance in productivity is explained by labor cost.

During a typical construction project, a contractor nay often find that the time originally available or normally expected to perform its work has been severely reduced. To finish the project by the completion date, the contractor is forced to find a way to speed up the progress of its work to compensate for the reduction in available time. The most frequent initial reaction of contractors to this situation is to increase on-site manpower by working longer time (overtime), adding more workers (overmanning), or implementing shift work (shift work) to increase the rate of progress. The goals of this study were to investigate how these three methods affect labor productivity and to quantify their impact on labor productivity by analyzing real project data collected from sheet metal contractors and mechanical contractors in the US.

This study surveyed 152 publicly traded companies to investigate group-performance based pay practices and its impacts on labor productivity. Compared a benchmark survey from Department of Labor, those companies show higher introduction rates, especially in small-to-medium sized companies. They also tend to pay profit-sharing bonus more in the form of company stocks and differentiate individual bonuses more by department performance than individual performance. The impact of group-performance based pay on labor productivity is positive and statistically significant. Economic value added per person in those companies adopting group-performance based pay tends to be higher and increases with the coverage of employees under the pay plan. It also reveals that the years after the play adoption are negatively associated with labor productivity.

The construction industry is an integral part of any nation's economy, whether measured by dollar volume or workforce size. In spite of its strong influence, there has been very little specifically aimed at evaluating the current industry performance. This research investigates the macroeconomic performance of the construction industry by accounting for crucial performance affecting factors such as labor productivity and gross margin. A clustering analysis, followed by a series of statistical analyses, yielded a notable finding that labor productivity is the most important factor that affects industry's profitability. The results of the analysis also revealed that the states with the strongest labor productivity show the highest level of profitability in terms of gross margin. This study should be of value to decision-makers when plotting a roadmap for future growth and rendering a strategic business decision.

Land reform in Korea was performed in 1949. The formation of owner farmers was the primary objective of land reform. But since land reform, the number of tenants has been increasing, and it reached to 65.7% of total farmhousehold by 1985. To analyze the productivity of tenant farming, 40 farmers in Kumnam, Yeongi Gun and Gongju Gun, Banpo, Chungnam Province, were selected as samples for the empirical analysis. The results of the empirical analysis are summarized as follows; 1. In plain area, tenants input 5% more labor, and 15% less capital than owner farmers. In mountain area, tenants input 15% more labor, and 4% more capital than owner farmers. 2. There is no difference in the output of rice between owner farmers and tenants in both area. 3. In plain area, the physical productivity of labor of owner farmers is 4.6 (kg/hour), and that of tenants is 4.4. And the physical productivity of labor of owner farmers in mountain area is 4.2, and that of tenants is 3.6. 4. The physical productivity of capital of owner farmers in plain area is 17.7(kg/1,000 won), and that of tenants is 20.6. In mountain area, the physical productivity of capital of owner farmers is 18.8, and that of tenants is 17.9.

본 연구는 2006년 부산광역시 선도기업을 대상으로 하여 교육훈련비가 기업의 노동생산성에 어떠한 영향을 미치고 있는지에 대해 1999~2008년의 기업자료를 사용하여 고정효과모형 및 2SLS방법에 의해 실증분석한 논문이다. 1인당 교육훈련비로 측정한 교육훈련은 통계적으로 유의한 수준에서 기업의 노동생산성에 양(+)의 영향을 미치고 있는 것으로 나타났다. 교육훈련의 효과성은 모든 기업에 동일하게 나타난다고 하기 보다는 기업특성에 따라 그 효과성에 차이가 존재할 개연성이 크므로 기업특성(기업규모, 산업분류)에 따른 차이를 분석한 결과, 대기업과 중소기업으로 구분한 기업규모는 통계적으로 유의한 차이를 발견하지 못하였다. 반면에 산업분류와 관련한 분석에서는 서비스산업의 교육훈련 효과성이 통계적으로 유의한 수준에서 타 산업에 비해 낮은 것으로 나타났다. 이러한 결과는 서비스산업에서의 교육훈련 프로그램의 보완이 시급하며 정책적인 지원을 통한 교육훈련분야의 다양화가 요구되는 근거가 된다고 할 수 있다.
