Knowledge creation has become one of core assets for companies' survival and success, companies are putting their effort to find the way to stimulate sharing knowledge among their workers. In this vein, the purpose of this study was to examine the effect of supervisor support and co-worker support on knowledge sharing and the mediating effects of work engagement. 328 employees from varity of organizations located in Korea particiapted for questionnaire survey. Structural equation modeling was used to analyze the data. The result has shown that the static correlation exists between supervisor support, co-worker support and work engagement. Co-worker support had positive influences on knowledge sharing intention. However, supervisor support did not have any influence on knowledge sharing intention. There was a mediate effect of work engagement between both of supervisor and co-worker support and knowledge sharing intention. The study implies that co-worker support is important in order to improve organizational learning and work engagement as a strategy to enhance organizational performance.

The purpose of this study is to derive implications for effective management of the public social worker by investigating the relationship between social support, job attitude and self-esteem of the public social worker. In order to accomplish this research purpose, social support of the public social worker as independent variables, job attitude as a dependent variable, and self-esteem as a parameter were analyzed and the relationship between these variables was analyzed. As a result, emotional, evaluative, material, and informational support, which constitute the social support of the public social worker, have a significant effect on job attitude, and self-esteem has a mediating effect on the relationship between these variables. Based on the results of this analysis, the importance of social support of the public social worker was suggested.

In nuclear power plant, it has been the important object to reduce the occupational radiation exposure (ORE). Recently, the optimization concept of management science has been studied to reduce the ORE in nuclear power plant. In optimization of the worker allocation, the collective dose, working time, individual dose, an total number of worker must be considered and their priority orders must be thought because the main constraint is necessary for determining the constraints variable of the radiological worker allocation problem. The ultimate object of this study s to look into the change of the optimal allocation of the radiological worker as priority order changes. In this study, the priority order is the characteristic of goal programming that is a kind of multi-objective linear programming. From a result of study using goal programming, the total number of worker and collective dose of worker have changed as the priority order has changed and the collective dose limit have played an important role in reducing the ORE.

The purpose of this study is to find the difference of household/work characteristics, family life satisfaction, and work satisfaction between home-based workers and out-of-home workers. The data of this study was collected from 230 married womens(home-based worker : 103 cases out-of-home worker : 127 cases) living in seoul. The major findings of the study are as follows. 1) Home-based worker's consumption expenditure structure, wive's housework time, schedule flexibility and degree of interruption, work loads were significantly higher than out-of-home workers. 2) Home-based worker's average monthly wage of her own and work time were significantly lower than out-of-home jokers. 3) Home-based worker's child care satisfaction and time use satisfaction were significantly higher than out-of-home workers. Out-of-home worker's self-fulfillment satisfaction, satisfaction of relation with supervisor, job stability satisfaction, work time satisfaction was significantly higher than home-based workers.

Unpaid Family Worker is blind area of industry safety. Danger of industrial accident is some high but because was excepted in industrial accident compensation insurance application. In most case, because paltry Unpaid Family Worker is no opportunity to take safety education to prevent industrial accidents and there are few safety facility and safety equipment, etc., among business, it may be said that probability to suffer industrial accidents on a trifling mistake or carelessness is higher than general worker of business. Consider such difficult actuality of Unpaid Family Worker and our country must give these benefit of industrial accident compensation insurance application, as opened the door of insurance application in recognition of worker position by "Industrial accident compensation insurance Law" to middle·smaller enterprise's business proprietor or special form labor employees.

This study deals with the productivity improvement on a flow production system with the consideration of line-balancing. In a flow production system, similar product models are produced on a same assembly line, the predefined process order and the limitation of total worker number. The system can be increased the work-in -process(WIP) inventory and the worker's idle time. In this study, the worker assignment model is developed to assign evenly workload of process to each product model in such a manner that each process has the different number of worker. This worker assignment model is the mathematical model that determines worker number in each process such that the idle time of processes is reduced and the utilization of worker is improved. We use a simulation technique to simulate the production line proposed by the mathematical model and apply real production line. With the result of simulation, this study analyzes the propriety of production line and proposes the alternatives of new production line

Numerical simulation using computational fluid dynamics (CFD) is performed to calculate the velocities and temperature profiles of air in adjacent to a worker within the individual local air conditioning system. The calculation domain is the space of ㄴ between walls and a worker in the climate room. The fresh air is supplied from the three different inlets located on the right, left and center wall in the climate room. In this study, the calculated data of velocities and temperature profiles of air in the nearest the skin of a worker are used to calculate the PMV (Predicted Mean Vote) for evaluation of thermal comfort of a worker in the local air conditioning system. Because the data of veto-cities temperature profiles of air in adjacent to a worker and the PMV of a worker are the design parameters of the local air conditioning system. The results of calculation show that the fresh air velocity and injection position are closely related to the PMV value. In individual air condition system of ㄴ, the appropriate PMV are obtained when the fresh air velocity and position are 1.0 m/s, throat of a worker and are 1.5 m/s, head of a worker, respectively. The method of numerical calculation is effective to obtain the optimum velocity and position of the fresh air for optimum the PMV and energy saving in individual local air conditioning system.

In traditional production lines, such as assembly lines, each worker is usually assigned to a particular fixed work, and decreasing the task to master the assigned work is valuated. However, when an imbalance exists between workers' speeds, if a worker delays the overall work in the production line, the production rate of the particular line will also decrease. To avoid this problem, the "Self-Balancing Production Line" was introduced. In this type of production line, each worker is assigned work dynamically, and when specific conditions are satisfied, production remains balanced. Characteristics of these lines that can be preempted at any place have already been analyzed by some researchers. A previous paper examined the situation in which only a single worker can process one machine and cannot preempt processing, and the improved policy of an ordinary selfbalancing production line, which specifies which stations workers can process and how workers can behave. This policy achieveda high production rate with only four stations and two workers (Buzacott, 2002). In that paper, worker processing stations and the behavior of a specific worker were limited, andthe paper focused only on specific stations and workers. Therefore, it is not applicable to any worker sequence. In this paper, we focus on other ways to decrease cycle time. In this kind of line, a worker processes at his or her speed. Therefore, if a worker is assigned stations according to his or her speed, the line can decrease cycle time. To do so, we relax the assumptions of this type of line and set a new condition. Under these conditions, we compare our results to the results of previous papers.
