The purpose of this study is to verify the effect of organizational culture on job satisfaction and to explore the moderating effect of locus of control. The study examined adhocracy culture among organizational cultures and divided into internals and externals for moderating effect of locus of control. The data analysis was used to SAS Ver 9.4 and PLS Ver 3.0. The test was conducted by 283 employees working at large, small-medium company and public enterprise in Mongolia. The results indicate that the positive adhocracy culture and job satisfaction were statistically supported. And this study found that internals moderating roles in the relationship between adhocracy culture and job satisfaction. Based on the findings of this study, the study presented managerial implications and suggestions for future studies.

The reactor internals shall be secured in safety and structural integrity under various vibrational loading conditions. Thus, U.S. NRC, Regulatory Guide 1.20 requires the evaluation for the reactor internals due to acoustic induced vibration including the response to the reactor coolant pump pressure pulsation. This paper suggests a methodology to develop an analytical model of the core support barrel accounting for the fluid around the structure and to analyze the responses to the pump pulsation loads using acoustic structure interaction analysis. The analysis results were compared with those of US Palo Verde 1 CVAP and showed a good agreement. Thus, it is expected that the suggested methodology could be an efficient way to evaluate the response of the core support barrel to the pump pulsation loads.

The purpose of this study is to reduce the costs required to proactively prevent the turnover intention by the results of personality type of locus of control. which is the behavioral outcome of the members of the organization. Based on this problem consciousness, the present study focused on the personal characteristics of the members of the organization in the enterprise. Among the individual characteristics, the intentions, which are distinct from others, are called personality, Focusing on the locus of control among these types of characteristics of the organization members, the study about how these control positions affect their job involvement and their turnover intention. The results validated in this study are summarized as follows. Among the personality types of the organization's members, internals are found to have higher job involvement than externals. In addition, it was found that internals among the personality types of the members of the organization lower the meaning of turnover intention than external member. In order to overcome uncertain management environment and create and sustain a competitive advantage in the organization, management has a weight-oriented trend and Increasing job involvement in organizational members and lowering their turnover intention will lead to continued productivity, among other things, important management items that managers and managers should pursue. Given these aspects, it is deemed necessary to analyze the personality aspects of the members of the organization and to transform and manage a new management mindset that leads to the enhancement of the personality as an internal rather than an external one and the task immersion of the members of the organization based on it.

The safety related components in the nuclear power plant should be designed to withstand the seismic load. Among these components the integrity of reactor internals under earthquake load is important in stand points of safety and economics, because these are classified to Seismic Class I components. So far the modelling methods of reactor internals have been investigated by many authors. In this paper, the dynamic behaviour of reactor internals of Yong Gwang 1&2 nuclear power plants under SSE(Safe Shutdown Earthquake) load is analyzed by using of the simpled Global Beam Model. For this, as a first step, the characteristic analysis of reactor internal components are performed by using of the finite element code ANSYS. And the Global Beam Model for reactor internals which includes beam elements, nonlinear impact springs which have gaps in upper and lower positions, and hydrodynamical couplings which simulate the fluid-filled cylinders of reactor vessel and core barrel structures is established. And for the exciting external force the response spectrum which is applied to reactor support is converted to the time history input. With this excitation and the model the dynamic behaviour of reactor internals is obtained. As the results, the structural integrity of reactor internal components under seismic excitation is verified and the input for the detailed duel assembly series model could be obtained. And the simplicity and effectiveness of Global Beam Model and the economics of the explicit Runge-Kutta-Gills algorithm in impact problem of high frequency interface components are confirmed.
