The latest society is very quickly changing so that it is placed in difficult life of not only the non-disabled people but also disabled people. The demand on welfare of the disabled people is continually increasing by the increasing in population of the disabled people by the expansion of the disabled realm and changing of family structure. The changing about the concept of the disabled, the spreading about the independence life, expecially the expanding about the awareness of the disabled human right, and the circumstance and the paradigm of the surrounded by the disabled welfare is rapidly changing. The right to work is related to the living, and is the important part of value endowment in the social participation and the self-realization, and is the core of the independence life. Therefore, this study is researched into the desire for work of the severely-disabled people in Cheong-ju City and their actual condition, so I present the desire of severely-disabled people and the suitable creation of the employment in Cheong-ju City, and the plan of the expansion of the disabled employment opportunity in my study.

Solar power generation systems require maximum power point tracking (MPPT) control to acquire maximum power using inefficient and high-cost PV modules. Most conventional MPPT algorithms are based on the slope-tracking concept. The perturb and observe (P&O) algorithm is a typical slope-tracking method. The two factors that determine the MPPT performance of P&O algorithm are the MPPT control period and the magnitude of the perturbation voltage. The MPPT controller quickly moves to the new maximum power point at insolation change when the perturbation voltage is set to large, and the error of output power will be huge in the steady state even when insolation is not changing. The dynamics of the MPPT controller can be accelerated even though the perturbation voltage is set to small when the MPPT control period is set to short. However, too short MPPT control period does not improve MPPT performance but consumes the MPPT controller resources. Therefore, analyzing the performance of the MPPT controller is necessary for actual insolation conditions in real weather environment to determine the optimum MPPT control period and the magnitude of the perturbation voltage. This study proposes an optimum MPPT control period that maximizes MPPT efficiency by measuring and analyzing actual insolation profiles in typical clear and cloudy weather in central Korea.

This paper that explain exchange rate determination using Korea's economy data moment investigate whether each theory cause effect that is some on exchange rate showdown analyzing actual proof relation between foreign exchange fluctuation and financing part variance examine wish to. Because korea economic enters in the 1990s and the 2000s and the change is notable, foreign exchange fluctuation by such change is real condition that is changing. In this paper, I wish to enforce actual proof analysis if change such as him is grasped by form that is some about foreign exchange fluctuation. First, the second chapter investigates exchange rate decision theory that is used on actual proof interpretation, and executes actual proof Test in reply in subsequent the third chapter. And finally, the fourth chapter wishes to drive conclusion of this paper.

I started this study to solve the doubt about actual condition of Oksosun stories. which was recorded in Cheonyerok(天倪錄) is the first form of Oksosun stories. But this story seems a very outstanding work. had a structure of romance. The hero's character was a romantic figure but Oksosun's character was a figure of Yadam. Afterward recorded in Gyeseoyadam(溪西野譚) and recorded in Cheongguyadam(靑邱野談) took place changes in the structure of the story. A lot of narrative paragraphs were removed in these stories. So and achieved the typical structure of Yadam. In recorded in Dongyahwijip(東野彙輯), the change of style was caused once more. So we can see the transmitting and changing flow of Yadam by this study; Romantic Yadam ${\rightarrow}$Typical Yadam , ${\rightarrow}$Noverized Yadam .

The final aim of this study was to propose guidelines for the indoor environment of apartment remodeling projects. The first task of this study was to understand the major elements and the actual condition of the remodeling for apartment unit by carrying out in-depth interviews on residents and specialists. The open-access interviews were conducted with interior designers who have a wide experience of apartment remodeling and residents who live in recently remodeled apartment units. The second task was to evaluate the actual condition of the indoor environment and to analyze the main factors that affect the indoor environment in remodeled apartment units. Field measurements were carried out in twenty apartment units occupied after remodeling, recording indoor environment elements (indoor temperature, globe temperature, relative humidity, $CO_2$, CO, PM10, TVOC, HCHO, illumination, and equivalent noise level). Moreover, resident interviews and researcher observations were carried out to determine the contents of the remodeled unit and to investigate the architectural and living factors(like ventilation characteristics, etc.) related to the indoor environment. The results are as follows. The remodeling elements generally included the changing of lighting fixtures and finishing materials in all the spaces, the integration of the balcony into the children's room, the installation of furniture in the kitchen and the entrance, the changing storage furnitures and equipments in the bathroom. The average levels of each unit of relative humidity, $CO_2$, TVOC, HCHO, equivalent noise level, and illumination were proved to be on the whole in inadequate condition. The factors that affect these indoor elements were classified as remodeling factors (remodeling amounts, extent balcony integration, and lighting fixture exchange), ventilation characteristics, and living factors. According to these results, this research proposed the guidelines for the indoor environment in apartment remodeling projects.
