Traditionally, the construction industry has shown low labor productivity and productivity growth. To improve labor productivity, it must first be accurately measured. The existing method uses work-sampling techniques through observation of workers' activities at certain time intervals on site. However, a disadvantage of this method is that the results may differ depending on the observer's judgment and may be inaccurate in the case of a large number of missed scenarios. Therefore, this study proposes a model to automate labor productivity measurement by monitoring workers' actions using a deep learning-based pose estimation method. The results are expected to contribute to productivity improvement on construction sites.

A genetic improvement program in Korea was implemented to improve the performance of Hanwoo cattle by generating livestock with genetically desirable economic characteristics. In particular, in response to external changes, such as the expansion of Free Trade Agreement (FTA), the livestock genetic improvement program has increased farm income by improving the productivity and quality of Hanwoo cattle. Using production cost data from Statistics Korea, the total input and output indices of Hanwoo feeding cattle from 2008 - 2021 were estimated and the growth and productivity changes were analyzed. The productivity change measures results were used to estimate the cumulative effects of the Hanwoo genetic improvement program on quality improvement, another purpose of the program, using a finite distributed lag model. The average annual increase in output (market weight) of Hanwoo was 0.9%. However, total input increased by 1.6%, resulting in a 0.6% decline in total factor productivity. In contrast, the Hanwoo genetic improvement program contributed significantly to the production of high quality beef, rather than contributing to improved productivity of the cattle. Hanwoo carcass weight, which is used as a performance indicator for the livestock genetic improvement program, has significantly improved and is projected to increase at a slower rate. The collective findings indicate the need for new performance indicators that can comprehensively indicate the performance of the genetic improvement of Hanwoo.

Purpose: The purpose of this study was to analyze the results of the productivity innovation partnership program and propose the method for improvement. We investigated 90 companies which are sub-contractors of Samsung Electronics, LG electronics, POSCO and so on. Methods: We developed and carried out a survey and analyzed the results of the program. The interviews are also performed. Results: This study shows that the partnership program is a effective method for improving quality and productivity of sub-contractors and it is necessary to extend coverage of this program. Conclusion: We suggested some improvement points of the partnership program and they are to be applied in the next year. The results show that the suggestion is helpful and valuable.

The objective of this study is In develope on productivity improvement program, which named PPM(Participative Productivity Management). This program consists of 3 stages which are Goal setting and sharing. Productivity measurement and evaluation, and Gain sharing. Each concepts of NGT(Nominal Group Technique), Objectives matrix method and Gain sharing was applied to form this frame. This program rewards members of an organization for their contributions to improve business results. It also fits perfectly with today's participative management philosophies. Furthermore, the company and its employees could be partners a win-win situation, and one more barrier to a high-involvement culture should be eliminated.

This study analyzed the factors that influence the research productivity of 236 graduate students who are funded by the Global Ph.D. Fellowship Program of the National Research Foundation of Korea. Research productivity was measured by the number of SCI publications, and the explanatory factors are the demographic factor, the financial factor, the reputation of institutions and the supervisor factor. This study included 2 indices such as the reputation of institutions and the research productivity of supervisors to check the halo effect unlike other studies. Results are as follows: 1) no gender difference, 2) better performance by younger age group, 3) no difference even if the students are additionally funded by other research support programs, 4) no halo effect by the reputation of institution but rather better performance from low ranked universities, 5) and a positive halo effect by supervisors.

Analytical hierarchy process (AHP) is a potential decision making method in management that can be used in project management as well. Lack of productivity is perhaps the number one problem confronting in the construction industry. There are numerous factors which affect the productivity of a construction project, so it is necessary to find out the critical factors giving birth to productivity. In this paper, construction productivity is taken as example for the demonstration of the AHP application to find out the critical productivity factor in which the Level 1 is taken as selection of critical productivity factor, Level 2 as construction parties and Level 3 as productivity factors group. The outcome of this study is beneficial to the entire constructional professionals for applying the AHP.

Background: We measured productivity changes of regional public hospitals using both global Malmquist productivity index-based on global production possibility set over all the periods-and the traditional Malmquist productivity index and analyzed the factors of productivity change. Methods: The data used in this study is two annual inputs and two annual outputs of 32 regional public hospitals in Korea from 2005 to 2009 and the results such as distances and Malmquist productivity index and global Malmquist productivity index are obtained by an R program written for this study. Results: The results can be summarized as follows. Firstly, technical efficiencies of regional public hospitals are affected largely by scale efficiency than pure technical efficiency. Second, productivity progressed and technological change has more significant influence on productivity advance over the period between 2005 and 2009. Third, the circularity problem of the traditional Malmquist index is confirmed, and so the global Malmquist index without this problem are valid for the analysis. Conclusion: Though this study also has some limitations with the data of regional public hospitals with a short time span, it is the first study of hospitals using global Malmquist productivity index and later it can be expanded to private hospitals and longer time periods.

본 연구는 간호사의 감성지능, 소진, 간호생산성과의 관계를 규명하고, 간호생산성에 미치는 영향요인을 파악하여 간호조직의 효율적 관리를 위한 기초 자료를 제공하고자 한다. 본 연구의 대상은 D광역시에 소재한 300병상 이상의 종합병원에서 근무하는 간호사 255명을 편의표집 하여 2013년 11월 12일부터 12월 26일까지 구조화된 설문지를 통해 자료를 수집하였다. 자료는 SPSS/WIN 17.0 program을 이용하여 t-test, one way ANOVA, Scheffe 사후검정, Pearson's correlation coefficient, enter multiple regression analysis하였다. 연구결과 임상간호사의 감성지능과 소진은 유의한 음의 상관관계를, 감성지능과 간호생산성은 유의한 양의 상관관계를 나타냈다. 감성지능, 총 임상경력, 소진, 직위가 간호생산성에 유의한 영향을 미쳤으며 간호생산성 변이의 43.4%를 설명하였다. 따라서 임상간호사의 감성지능을 향상 시킬 수 있는 중재프로그램을 다양하게 개발하여 소진을 낮추고 간호생산성을 높일 수 있도록 경력자 관리에 대한 간호조직의 효율적 운영과 전략 구축이 절실히 요구된다.

The purpose of this study is to review in light at women's subjective. Perceptions of manifestations Premenstrual Syndrome which are known to affect their labor productivity. To this end, 364 women workers were sampled from an industrial factory located in Chonan, Chungchongnam-do and supervised by health manager, through questionnaires, and collected data were processed using SPSS package program. The result of survey can be summarized as follows: The fact that some academic circles are recently raising the issue of premenstrual syndrome. Suggests that the syndrome is being accepted in academic terms, which is contary to the position that the syndrome is just the result of women's mental imagination. However, some factors which are concived to affect woman worker' productivity and efficiency seem to be related to their subjective psychological variables involving their working environment rather than their physiological variabls. Therefore, if a health-promotion program handling their subjective psychological variables be introduced, some factors caused by the pre-menstrual syndroml may be reduced thus increasing their working productivity and. efficiency around their menstrual days.
