The purpose of this study is to minimize physical obstacles for handicapped students in university dormitories. To carry out this study, we have surveyed 10 Universities in Korea. First we have studied the law and the theory of architectural planning and design guides those are related with handicapped people. And it was surveyed the existing state of the dormitories facilities and made a checklist. And the satisfaction about the facilities was questioned to the handicapped students who used those buildings. It is concluded that most of the universities which we have surveyed were equipped with good facilities for the general students but don't have regards for handicapped people at that time. As the result of the rate of the satisfaction, they are satisfied those facilities generally. As you can see the result of this research, the facilities in University are not very good for handicapped people in many points. So that kind of many facilities must be taken into consideration for handicapped people in the stage of architectural programming in the process of designing the dormitory building.

Single crystal $ZnIn_2S_4$ layers were grown on thoroughly etched semi-insulating GaAs(100) substrate at $450^{\circ}C$ with hot wall epitaxy (HWE) system by evaporating $ZnIn_2S_4$ source at $610^{\circ}C$. The crystalline structure of the single crystal thin films was investigated by the photoluminescence (PL) and double crystal X-ray rocking curve (DCRC). The temperature dependence of the energy band gap of the $ZnIn_2S_4$ obtained from the absorption spectra was well described by the Varshni's relation, $E_g(T)=2.9514\;eV-(7.24{\times}10^{-4}\;eV/K)T^2/(T+489\;K)$. After the as-grown $ZnIn_2S_4$ single crystal thin films were annealed in Zn-, S-, and In-atmospheres, the origin of point defects of $ZnIn_2S_4$ single crystal thin films has been investigated by the photoluminescence (PL) at 10 K. The native defects of $V_{Zn}$, $V_S$, $Zn_{int}$, and $S_{int}$ obtained by PL measurements were classified as a donors or acceptors type. And we concluded that the heat-treatment in the S-atmosphere converted $ZnIn_2S_4$ single crystal thin films to an optical p-type. Also, we confirmed that In in $ZnIn_2S_4$/GaAs did not form the native defects because In in $ZnIn_2S_4$ single crystal thin films existed in the form of stable bonds.

[ $CdGa_2Se_4$ ] 단결정 박막을 수평 전기로에서 합성한 $CdGa_2Se_4$ 다결정을 증발원으로하여, hot wall epitaxy(HWE) 방법으로 증발원과 기판(반절연성-GaAs(100))의 온도를 각각 $630^{\circ}C,\;420^{\circ}C$로 고정하여 성장하였다. 이때 단결정 박막의 결정성은 광발광 스펙트럼과 이중결정 X-선 요동곡선(DCRC)으로 부터 구하였다. Hall 효과는 van der Pauw 방법에 의해 측정되었으며, 293K에서 운반자 농도와 이동도는 각각 $8.27{\times}10^{17}cm^{-3},\;345cm^2/V{\cdot}s$였다. $CdGa_2Se_4/SI$(Semi-Insulated) GaAs(100) 단결정 박막의 광흡수와 광전류 spectra를 293K에서 10K까지 측정하였다. 광흡수 스펙트럼으로부터 band gap $E_g(T)$는 Varshni 공식에 따라 계산한 결과 $E_g(T)=2.6400eV-(7.721{\times}10^{-4}eV/K)T^2/(T+399K)$였다. 광전류 스펙트럼으로부터 Hamilton matrix(Hopfield quasicubic mode)법으로 계산한 결과 crystal field splitting 에너지 ${\Delta}cr$값이 106.5meV이며 spinorbit 에너지 ${\Delta}so$값은 418.9meV임을 확인하였다. 10K일 때 광전류 세 봉우리들은 $A_{1^-},\;B_{1^-}$와 $C_{11}-exciton$ 봉우리임을 알았다. Single crystal $CdGa_2Se_4$ layers were grown on a thoroughly etched semi-insulating GaAs(100) substrate at $420^{\circ}C$ with the hot wall epitaxy(HWE) system by evaporating the polycrystal source of $CdGa_2Se_4$ at $630^{\circ}C$. The crystalline structure of the single crystal thin films was investigated by the photoluminescence and double crystal X-ray diffraction(DCXD). The carrier density and mobility of single crystal $CdGa_2Se_4$ thin films measured with Hall effect by van der Pauw method are $8.27{\times}10^{17}cm^{-3},\;345cm^2/V{\cdot}s$ at 293 K, respectively. The photocurrent and the absorption spectra of $CdGa_2Se_4/SI$(Semi-Insulated) GaAs(100) are measured ranging from 293 K to 10 K. The temperature dependence of the energy band gap of the $CdGa_2Se_4$ obtained from the absorption spectra was well described by the Varshni's relation $E_g(T)=2.6400eV-(7.721{\times}10^{-4}eV/K)T^2/(T+399K)$. Using the photocurrent spectra and the Hopfield quasicubic model, the crystal field energy(${\Delta}cr$) and the spin-orbit splitting energy(${\Delta}so$) far the valence band of the $CdGa_2Se_4$ have been estimated to be 106.5 meV and 418.9 meV at 10 K, respectively. The three photocurrent peaks observed at 10 K are ascribed to the $A_{1^-},\;B_{1^-},\;and\;C_{11}-exciton$ peaks.

다이캐스팅 공정은 정밀한 금형에 용탕을 압입시켜 고정도의 주조표면을 갖는 주물을 대량 생산하는 기공방식이다. 성형체의 정밀성과 주조 후처리 과정의 간소화, 자동화의 용이성 등의 장점으로 인해 산업 전반에 걸쳐 널리 사용되고 있다. 본 논문은 LPI 자동차 레귤레이터 제품은 고압의 내압을 받으며, 품질 성능에 따라 자동차의 가장 기본적인 연료공급 시스템의 핵심 역할을 한다. 고품질화된 성형제품 생산을 위하여 결함의 발생원인에 대한 이해를 통해 제조공정에서 발생하는 결함을 예측하고, 특히 오버플로우의 개소에 따라 제품의 성형에 관한 신뢰성을 증명하고자 하였다. This study examined the casting analysis of fuel pressure regulator of LPI vehicles. We aims to predict all the phenomenon accompanied by flow and solidification in die casting, and maximize productivity and quality through optimal casting design. As a result of comparing Types A and B of casting design, it was found that the number of overflow affected flow, flow speed and solidification temperature. And there was a minute difference between solidification temperatures at thick section of the spare parts. Solidification began at temperatures of 624℃ ~ 630℃, but after the casting was completed, temperatures at the center of the parts were 600℃ ~ 614℃. Temperature of molten metal showed optimal flow at temperature of 680℃. It began to solidify around at 650℃, and to be cooled between 580℃ ~ 550℃ in high speed. When the process was analysed through a computer simulation, it was found that hardness of regulators manufactured through Type B of overflow was above H<SUB>R</SUB>60.

The elderly patients are the most frequent users of digoxin because of increased prevalence of the two primary indications for digoxin therapy; atrial fibrillation (AF) and congestive heart failure (CHF). This study was Performed to observe a variation in digoxin pharmacokinetic parameters in advancing age and changing kidney function, and to compare the measured clearance with the calculated clearance. The 123 drug monitoring records of inpatients who had achieved steady state concentration of digoxin at a tertiary hospital from April 1999 to October 2001 were reviewed. In advancing age, measured digoxin clearance, volume of distribution and creatinine clearance were reduced. Compared with the calculated digoxin clearance, the measured digoxin clearance was more reduced in patients without CHF Especial1y: in elderly patents without CHF the measured digoxin clearance was lower than the calculated digoxin clearance. In contrast to non-CHF patients the measured value was greater than the calculated value in all CHF patients. Findings from this study indicate that the calculated digoxin clearance in elderly patients without CHF substantially overestimated the true clearance. Thus, it appears that the use of calculated digoxin clearance to estimate serum digoxin concentration may result in underestimation of the true serum concentration in a number of elderly patients without CHF.
