The trouble of business management of the mining and manufacturing companies in Korea are constituted by that average 28.3% of production management in the worst trouble of business management from 1973 to 1980 So that Industrial productivity in Korea lower than an industrially advanced nation and then a change for the better of effective production management operations manufacturing companies are suggested by the application effects and achievement points of production management. Therefor Industrial Engineering technics is applied systematic route and the manufacturing company grow more than better its Business Physical condition for the improve productivity applied system approach for a rational product ion management system model.

This paper presents the experimental results to verify the environmental consciousness with economic balances due to cutting fluid behaviors, effectiveness in machining process. Even though cutting fluid improves the Productivity through the cooling, lubricating effects, its environmental impact is also increased according to the cutting fluid usage. The primary mechanism considered in this study is the spin-off motion of fluids away from rotating workpiece. In this study some parameters arc adopted to analyze the productivity(tool wear), environmental impact(mist diffusion rate). The results present talc criteria for the resonable cutting fluid usage quantitative1y to develop the environmentally conscious machining process.

In the recent, it is gradually important for airport to consider environmental aspects as sustainable development is emerged. ICAO, FAA and individual countries has tried to reduce airport noise and pollution. Thus, the effort is needed to incorporate environmental factor into productivity indicator of airport. Our paper use DEA method with the non-parametric directional output distance function(DDF) to assess productivity of 14 airports in Korea during 2008~2010. In addition to three inputs, two conventional outputs, two undesirable outputs have been considered : noise and air pollution. Results are compared from models that do not include undesirable outputs. Inclusion in the analysis of the undesirable effects of airport operations leads to greater and closer airport's efficiency scores.

In spite of the well confirmed advantages of wilting on the fermentation quality, wilting silages are difficult to make at optimum dry matter content. The prolonged wilting, especially in humid condition, result in lower water soluble carbohydrate (WSC) contents, extensive protein breakdown and sometimes higher total volatile fatty acid (VFA) during wilting an ensilage. Apart from difficulty of controlling moisture content, another problem associated with wilted silages is different evaluation on the potential productivity. In temperature climate of Asia, therefore further researches on the effects of wilting on the silage fermentation and potential productivity seen to be necessary.

Despite the growing interest in technostress phenomenon of employees in organizations, few guidelines exist about how mangers can effectively control their technostress. Accordingly, scholars should pay greater attention to how firms can successfully manage employees' technostress. This study conceptually developed and tested a research model for understanding the influence of technostress on psychological and behavioral strains. In addition, we tested technical support provision as a moderator. We obtained 107 samples through a survey questionnaire, and data were analyzed based on structural equation modeling (SEM). As a result, it was empirically demonstrated technostress decreases job satisfaction and individual productivity. We also found that technical support provision have moderating effects on the relationship of technostress and job satisfaction/individual productivity.

Traditional CVP (Cost-Volume-Profit) analysis employs linear cost and revenue functions within some specified time period and range of operations. Therefore CVP analysis is assumption of constant labor productivity. The use of linear cost functions implicity assumes, among other things, that firm's labor force is either a homogenous group or a collection homogenous subgroups in a constant mix, and that total production changes in a linear fashion through appropriate increase or decrease of seemingly interchangeable labor unit. But productivity rates in many firms are known to change with additional manufacturing experience in employee skill. Learning curve is intended to subsume the effects of all these resources of productivity. This learning phenomenon is quantifiable in the form of a learning curve, or manufacturing progress function. The purpose d this study is to show how alternative assumptions regarding a firm's labor force may be utilize by integrating conventional CVP analysis with learning curve theory, Explicit consideration of the effect of learning should substantially enrich CVP analysis and improve its use as a tool for planning and control of industry.

본 연구에서는 정부의 사업주 직업훈련지원제도가 교육훈련투자를 촉진하고, 촉진된 교육훈련투자가 생산향상으로 이어지는지를 기업체 자료를 이용하여 실증분석해 보았다. 분석 결과 정부지원이 기업의 교육훈련투자를 촉진하는 효과가 중소기업에 비해 대기업에서는 분명히 관찰되고 있지 않다. 또 정부지원을 통한 교육훈련투자 증가는 대기업보다 중소기업에서 보다 분명히 생산성향상 효과가 나타났다. 한편 교육훈련투자 수준이 높은 기업일수록 정부지원을 통한 교육훈련투자의 성과향상 효과가 훼손되는 것으로 분석되었다. 따라서 상대적으로 더 높은 수준의 교육훈련투자를 하고 있는 대기업에 대한 정책 효과가 중소기업에 비해 제한적인 것으로 보인다.

Purpose : The purposes of this study is twofold: (a) to investigate the effect of job stress and organizational climate on the organizational effectiveness of hospital nurses, and (2) to examine the moderating effect of organizational climate on job stress. Method : Three organizational effectiveness variables(e .g., job satisfaction, organizational committment and group productivity) as outcomes variables were examined. The sample consisted of 602 nurses from 5 general hospitals affiliated university. Data were collected with self-administrated questionnaires and analyzed using hierarchical regression. Results : It was found that: (a) seven job stress variables(e. g., workload, role conflict, schedule, lack of knowledge, conflict with superior, conflict with other personnel and conflict with patients) have negative effect on job satisfaction and organizational committment; (b) organizational climate have positive main effects on job satisfaction and organizational committment; (c) the negative effects of job stress variables on job satisfaction and organizational committment are not moderated by organizational climate. Conclusion : Organizational climate mediates the effects of job stress on group productivity, but the size of the mediating effects was small. Various outcome variables need to be discussed further research.

The objective of this study was to determine effects of humic acid (HA) and blueberry leaf powder (BLP) supplementation in pig feed on productivity, blood profiles, and meat quality characteristics of longissimus muscle. The experimental design included six treatments: 1) CON, no addition; 2) T1, BLP 0.1%; 3) T2, BLP 0.2%; 4) T3, humic acid 2%; 5) T4: humic acid 2%+BLP 0.1%; and 6) T5: humic acid 2%+BLP 0.2%. HA and BLP supplementation in pig feed significantly increased average daily feed intake (ADFI) values (p<0.05). HA supplementation in pig feed had beneficial effects in lipid profiles without altering feed efficiency rate (FER). HA and BLP co-supplementation in pig feed decreased pH in longissimus thoracis (p<0.05). In addition, sensory characteristics were enhanced when pig feed was supplemented with HA and BLP without causing adverse effects in meat quality. Taken together, addition of HA and BLP in pig feed may produce functional meat products.
