The simplified simulation technique for the best generation mix is developed and the studied results are described. The best generation mix over study time from the economic point of view can be easily constructed by this technique. Generator maintenance, the operation of pumpgenerator and LNG thermal generator with limited energy are simulated variously, so a role of each generator is also easily evaluated. Through parametric analysis, useful planning guide points are obtained for the best generation mix transition, nuclear power plant construction cost, ruanium cost , oil cost, coal cost and midnight factor in the study case corresponding to real power system size model.

1. Purpose : Clinically I have studied efficacy of herb treatment and development of herb growth palpation about handicapped children for growth. 2. Methods : 165 patients who visited hospital from January, 2000 to January 2001 3. Results : Average growth of children who visited hospital was less than 4cm but boys have grown 9.8cm/year and girls grown 7.8cm/year at average after treatment by herb. 4. Conclusion : In case of decreasing growth to have get less growth hormone, it has confirmed positive effectiveness by herb treatment even if it is normal.

The research develops measurement processes for estimating and evaluating the gauge R&R(Reproducibility & Repeatability) using ANOVA(Analysis of Variance) of experimental design tools. The ten-step processes developed include experimental goal setting, the selection of characteristics(factors, levels), data model, ANOVA, EMS(Expected Mean Square), estimation of gauge precisions, and evaluation indexes. The three-factor combined measurement models are presented to show the processes developed in this paper.

This paper presents the policies Korea adopted to educate and train scientists/researchers and technicians/skilled workers. The Korean policies for the increase of human resources in science and technology that stimulated an upgrading of skills in industry and adapted to technical advancements are identified. An important factor is that the supply and demand mechanism created a virtuous circle so that the science and technology education and training policies were responsive to economic demands. In addition, policies to foster a human resource capacity have enhanced the contribution of human resources in science and technology for innovation and economic growth.

The purpose of this study was to develop an assessment scale of the profile of kindergarten teachers. The subjects were 287 kindergarten teachers. Data were collected from June to September in 1997. Construct validity and reliability were analyzed using factor analysis and Cronbach Coefficient Alpha. Factors were extracted in the order of: characteristic traits, professional knowledge, specialized function, knowledge of liberal arts, cognizance of professionalism, and occupational consciousness. The Cronbach Coefficient Alpha of the selected 30-item assessment scale was .9068.

This paper describes an evaluation of reinforcement tension in RC beams using the variable truss models. The models were examined with the beam test results by Kim, Kim and White. Consequently, a fixed inclination $\theta$ at the support un-explains global state of internal force flow in cracked reinforced concrete beams subjected to shear and bending. Accordingly, we must introduce the arch factor for development of consistent model in reinforced concrete beams subjected to shear and bending

This study analyses factors facilitating work-family balance through quantitative research and case study. A sense of balance is more closely related to cognition and satisfaction in work and family than demographic factors. Based on these results, two kinds of educational programs for employees and employers were developed. Both programs consist of 4 sessions and focus on the necessity of work-family balance and the application of family-friendly policie.

In this paper a development of 10KVA series-parallel compensated UPS is shown, which has high input power factor and sinusoidal output voltage regulation capability. Compared to conventional cascaded UPS, the size can be reduced significantly with high quality input and output waveforms. The front converter and the main inverter can be considered decoupled, hence the front converter and the main inverter can be designed independent of each other. In this paper, analysis and experimental results for an 10 KVA prototype are presented.

In the finite element analysis of semiconductor devices analysis, the solution often be diverged due to the numerical instability of discretized equations. To overcome this problems, a noble finite element code which guarantees a successful convergence is developed. The factor of divergence in the current continuity equation of semiconductor governing equations is derived using stability test and an adaptive mesh refine scheme is introduced to eliminates the divergence properties. A test calculation of GaAs MESFET model reveals that the proposed scheme has a robust self-convergence property and is suitable for the semiconductor devices analysis.
