The purpose of this study is to investigate the characteristics of 1990s' apartment planning in Korea by analysing newspaper advertisements. It uses content analysis method on apartment newspaper advertisements from 1990 to 1999. The result investigation were classified both as qualitative and quantitative materials. The results of this study are as follows. 1) Categorizing contents of apartment newspaper advertisements as some main architectural planning characteristics. 2) Qualitative analysis of what contents are included in categorized planning characteristics. 3) Quantitative analysis of comparing relative frequency of planning characteristics.

This study made an investigation concerning the extra time allowed for the convenience of the people with a disabled hand who are taking word processor qualification examination, one of IT qualifying examinations. Then an experiment was conducted to determine whether it is proper to allow longer extra time for them. The experiment involved the one-handed and two-handed typing training of the same participants, followed by testing the participants’ typing proficiency, so as to find out approximate difference in the number of keystrokes between one-handed typing and two-handed typing. The results of the experiment were combined with the analytical result of available mock word processor tests to deduce the proper time that is actually necessary for one-handed typing. Then the deduced proper time was compared with the time that is currently allowed for people with a disabled hand. It was revealed that the typing speed of people with a disabled hand was about 32.6% of that of normal people, indicating that an about 50% extra time should be allowed for people with a disabled hand. Currently only a 33% extra time is allowed for them, and this difference in extra time can exert a significant effect on pass rate. Thus this study demonstrated the necessity of allowing longer extra time for people with a disabled hand than the current 33% extra time. IT 자격시험 중 하나인 워드프로세서 자격시험을 한손 장애인이 응시할 경우에 제공되는 편의시간에 대하여 조사한 후, 추가 제공시간이 타당한지에 대한 연구를 진행하였다. 연구는 동일인이 양손타수와 한손타수 연습 후 타자검정을 통하여 어느 정도의 타수 차이가 발생하는지를 실험하였고 실험결과를 실제 워드프로세서 모의문제 분석결과에 대입하여 실제 시험시간을 도출하여 비교분석하였다. 한손장애인은 비장애인에 비해 약 32.6%의 타자속도를 가질 수 있어 약 50%의 추가 시간이 필요한 것으로 파악되었다. 이는 합격률에 큰 영향을 미칠 수 있어 현재 제공되는 33%의 추가시간보다 더 많은 시간이 필요함을 증명하였다.

The morphologies of MC carbides (M stands for metal) and creep-rupture properties in directionally solidified Rene 80 having standard and Hf-modified chemistries were studied. It was found that Hf depressed the melting point, $\gamma$- $\gamma$’ eutectic temperature and $\gamma$’ solvus of nickel-base superalloy Rene 80, but did not depress MC carbide forming temperature. The morphologies of MC carbides depended upon solidification sequence, which led to blocky type in the early stage and script type in the late stage of solidification. Creep failure occurs through the crack initiation at the transverse components of longitudinal grain boundaries or interdendritic carbides in directionally solidified superalloys. It could be concluded MC carbide morphologies played an important role in creep properties of DS superalloys, that is, Hf additions increased the creep ductilities and lives of Rene 80.
