Materials are limited for pest control and chemical pesticides are prohibited in organic farming. Thus, the concept of pest control may not be effective for pest management in organic farm. As an alternative approach, landscape management is potentially effective and useful approach for preventing pathogen and insect pests in organic farm. It is needed to develop best practices utilizing functional biodiversity for pest management through landscape management. For this purpose, we investigated the effect of companion plants on species richness of insect pests and natural enemies in the field border area and in the crop plants (rice and soybean). In rice paddy fields, Lysimachiae foenum-graecum, Saururus chinensis were selected as effective companion plants on the paddy field levee for conserving Arachnidae as natural enemy and density suppression of insect pest such as Lissorphoptrus oryzophilus, Riptortus clavatus. As a result, damage rate of rice plant by insect pests was significantly lower (2.5%) and yield rate of healthy grains was significantly higher (8.7%) than control. In soybean fields, Marigold plants such as Tagetes patula, T. officinalis, increased Arthropod species richness and ratio of natural enemy group, and decreased ratio of insect pest group. As a result, yield (weight of 100 seeds) of healthy soybean was significantly increased (2.5%) than control. The 2nd infection rate from damage by R. clavatus was significantly lower in the treated plot than that in control. Thus, yield rates of healthy soybean in the control and the companion plant-treated plot were 79.0% and 84.3%, respectively, compared to conventional farming using chemical pesticides. Therefore, use of companion plants on field border was an effective practices for preventing pest insects and increasing yield in organic farming.

The purpose of the present study was examine the effects of group contingency management strategy in elementary school physical education setting on the problem of student managerial time for physical education class and to assess three subject teachers t

If done under this circumstances, then labor force can work comfortably and safely without nervousness and tiresome. The productivity and quality can increase ultimately and even foreign labor, imbecile child, old-aged labor can participate in work, which can reduce shortage of labor source. Therefore, in this study, it would be researched how to manage work blunder system by domestic small and medium enterprises and would be examined work blunder system was developed to fully meet the worker satisfaction. Through this 5M factor evaluation system by AHP(Analytic Hierarchy Process) all analyzed.

Considering in view of China's low price and Japan's high technology, the most important point is the quality of product. To increase the comparative power internationally all workingmen have to fulfill the responsibility to maximize the quality, and this is possible practiced under 'Zero Defect' spirit. To reduce the defect ratio to 'Zero' the workingmen have to recognize own fault, all the manufacturing process should be conducted under 'Fool Proof System', If done under this circumstances, then labor force can work comfortably and safely without nervousness and tiresome. The productivity and quality can increase ultimately and even foreign labor, imbecile child, old-aged labor can participate in work, which can reduce shortage of labor source. Therefore, in this study all defects in manufacturing process, it would be recognized the errors and mistakes caused by human.

TPM(Total Productive Management) that is enforcing introducing more than 80% in domestic manufacturing industry is using total plant efficiency by the evaluation index, and as a result, can see a lot of examples that plant productivity is increased. This study's purpose centers total productive management activities that is management system for total plant efficiency's maximization, plant information system that total productive management activities factor that is enforcing in manufacturing industry can develop evaluation model that can evaluate qualitative activities by quantitative activities in process that maximize total plant efficiency wishes to do design.
