  • In korea, since November 1982 these two small group activity (QC circle convension and Factory Saemaul activity small group convension) has been united, many problems have been disclosed that are aganist the basic principle more or less. Worker's small group within their working place to improve the surroundings creatively. In practice, however, many group are so typical and impetuous of the material effect that it is worried to be inclined to outform rather than contents. Effective small group activities are presumed to be successful only with labour management cooperation on the basis of human-orient management philosophy. The small group activities are also prevalent in service sector. More derivative methods have been developed and more members are willingly participation in training programs. The small group which is basically a horizontal organization unit, promptes communication within the whole organization, In consideration of social circumstances and traditions, the flexible model of the small group activities suitable to the corporate environment, will contribute to industrial development.

  • Large dams are managed with operation standard and flood forecasting systems, while small dams do not have management method generally. Shortage of water resources and natural disasters due to drought and flood raised public concerns for management of small dams. Most of small dams are irrigation dams, which need diversified water uses. However, the lack of systematic management of small dams have caused serious water wastage and increased natural disasters. Storage management method and system were developed to solve these problems in small dams. The system was applied to Seongju dam for effective management. The storage management method was established considering hydrology simulation and statistical analysis using the system. This method can bring additional available water, even in the same conditions of the water demand and the supply conditions of watershed. It can improve the flood control capacity and water utilization efficiency by' the flexible operation of storage space.

  • This study made a nationwide metropolitan region map on the basis of disaster vulnerability and administrative boundary, and based on it, it divided small-sized regions and constructed disaster history of each region. For the disaster vulnerability, the study wrote slope, aspect, curvature, wetness index, and drainage density, compared and analyzed regions with disaster and geomorphic elements to distinct the factor with high correlations, and based on it, it divided small-sized regions for forecasting and warning system of middle regions(Gangwon province, Chungchung province, and Jeolla province). Through the method, Gangwon region were divided into 4 small-sized regions, Chungchung into 5 small-sized regions, and Jeolla into 6 small-sized regions.

  • The purpose of this study is provide better suggestions to utilize the small aircraft by examining current situations of those airports. Then, the results of this study should help explain about the Availability of the airports for small aircraft in view of airplane exhibition, air-sports activity fields for aviation sports population, aviation theme park, and aviation-related education facility. This study examines current situations of the small airports for small aircraft which have been limited in their utility and compares the airports at the same level abroad. By examining these airports, this paper can make suggestions for the Availability of the small airports. Significance of the study lies in providing businessmen planning to invest the small airports and owners of airports with profitable consequences. At the macro level, it is expected to have a more effective development of land and an increase of aviation market value.

  • The behavior of fatigue was studied by using low carbon steel bar with microhole(artificial small defect) under the condition of rotary bending stress which is made artificially at smooth surface and round notch root. The results obtained can be summerized; The behavior of non-propagating cracks which are produced at both tips of small defect occurred to dissymmetry, and it is found to be double size of small defect. For the range of l>lc, threshold stress intensity is constant. However, for the range of l

  • In this paper we study pooling effects in Bayesian testing procedures of independence for contingency tables from small areas. In small area estimation setup, we typically use a hierarchical Bayesian model for borrowing strength across small areas. This techniques of borrowing strength in small area estimation is used to construct a Bayes test of independence for contingency tables from small areas. In specific, we consider the methods of direct or indirect pooling in multinomial models through Dirichlet priors. We use the Bayes factor (or equivalently the ratio of the marginal likelihoods) to construct the Bayes test, and the marginal density is obtained by integrating the joint density function over all parameters. The Bayes test is computed by performing a Monte Carlo integration based on the method proposed by Nandram and Kim (2002).

  • The impulse noise of bullet after shooting in small arms has an effect on the hearing ability of human. Although a silencer has been developed for noise reduction in small arms, there is only a few researches about relationships between the sound pressure level and the auditory sense of human. In this study, the quantitative sound pressure levels are revealed by experimental measurements of impulse noise with each silencer type. And the performance evaluation for noise suppression of a silencer in small arms is carried out to reduce a serious loss of the hearing ability of the small arms user. It is concluded that the evaluated results can be utilized for checking sound pressure and data accumulation for new small arms design with silencer.

  • This review focuses on the clinical use of $^{18}F-FDG$ PET in small cell lung cancer. For initial staging of small cell lung cancer, $^{18}F-FDG$ PET appears to be better than conventional staging methods. $^{18}F-FDG$ PET seems to be potentially useful for detecting recurrence, restaging and therapy response assessment in small cell lung cancer. However, due to small number of literatures, the role of $^{18}F-FDG$ PET in small cell lung cancer requires further investigations.

  • An effect of carbon tetrachloride (CCl$_{4}$) was studied on the xanthine oxidase(XOD)activity of small intestine in male rats. Concomitantly a cause of increasing small intestine XOD was focused on an effect of actinomycin D and the kinetics of partial purified XOD frdm small intestine in CCl$_{4}$ intoxicated rats. An injection of CCl$_{4}$ to the rats showed an increase of small intestine XOD. In the pretreatment of actinomycin D before injection of CCl$_{4}$ to the rats, the XOD activities of small intestine were significantly decreased. In the partial purified enzyme preparation, the small intestine XOD in CCl$_{4}$ intoxicated rats showed the more increased Km and Vmax value with xanthine as substrate than that of control group.
