This study on the correlation between academic achievement and admission process was performed on a group of students who are majoring clinical pathology at Daegu Health College, Academic achievement of a group of students was evaluated on the basis of their average GPA of whole semesters enrolled at the college, In terms of admission type, Bachelor (Dae-Jol) group showed the best GPA among all groups, followed by General (Il-Ban), Rural(Nong-Oe-Chon) and Special (Teuk-Byul) group in a row. From the view point of admission time, Regular Admission (Joeng-Si) group showed a little bit higher GPA than Early Admission (Soo-Shi) group. When classified by the graduated-high schools, the GPA of the students who are from General high school (In-Moon-Kye) was higher than that of those who graduated Technical high school (Shil-Up-Kye). By the gender, female students exceeded male students in GPA in the first (freshman) and the second (junior) year of the college. However, in the third (senior) year, male students exceeded female students. In a conclusion, in order to select the applicants with better academic capability it may be needed to put more importance on General (Il-Ban) admission by type and Regular Admission (Joeng-Si) by time during the new students admission assessment. In addition it is also recommended to give some preferential treatment to the applicants from General high school (In-Moon-Kye).

The use of Pre-processor for building structural analysis used to rely upon filling up fixed format data, which was ineffective and error-prone. This research attempts to integrate structural analysis system with DBMS and CAD system in order to make it easy to exchange data between pre-process, analysis, and post-process stages. Automatic generation of database from pre- process stage allows easy preparation of main input data for other structural analysis programs. CAD system with some sub-programs written in LISP and C works as a graphic user interface. This approach gives an easy, effective and error-free way of inputing data for structural analysis.

This paper presents an integrated machining error compensation without measuring cutting force in micro end-mill. To compensate machining error, we consider new tool path. In order to determine the compensated tool path, two machining error parameters are defined and modeled using the SEM images. Experiments are carried out to validate the approaches proposed in this paper. In result, we identify the proposed methods are effective to compensate for machining errors.

This study is to investigate the characteristics of products on mixing ratio of raw materials for scoria tile manufacturing. The water absoprtion of scoria tile decreased as scoria particle size decreased and a ratio of scoria/sand increased. And also the water absoprtion of tile decreased as an amount of cement decreased. Smaller scoria particle size, smaller ratio of scoria and sand, and larger amount of cement enhanced strength and thermal conductivity of scoria tile. The surface pattern of scoria tile became various figures as a ratio of scoria and sand increased. Well mixing of large and small particles made surface pattern of tile diverse.

본 연구는 한국인의 삶의 질 향상을 위한 국민 생활체육 진흥정책 수립에 필요한 기초자료를 제공하기 위하여, 건강한 30-60대 서울시민(313명)의 체격과 근력, 전신지구력 등의 체력을 측정하여 문화, 경제생활수준이 서로 빠른 동경시민(509명) 및 북경시민(160명)과 비교 검토하는 것을 목적으로 하였다. 각국의 연구대상에 대한 측정은 사전에 협의한 동일한 방법(동경대학 체육과학실법)과 기기를 이용하였다. 체격요인으로는 신장과 체중을, 체력요인으로는 트레드밀 보행시 (90m/분)의 심박수와 보폭 그리고 자전거 에르고미터 운동시의 PWC75%HRmax와 脚筋伸展파워를 측정하였다. 신장 및 체중, 신체질량지수는 남녀 모두 북경, 서울, 동경시민순으로 높게 나타났다. 트레이드밀 보행시의 심박수는 남녀 모두 북경, 동경, 서울시민 순으로 낮은 값을 보였으며, 신장에 대한 보폭비율은 남자의 경우에는 북경, 서울, 동경의 순으로, 여자는 북경, 동경, 서울의 순으로 높았다. 脚筋伸展파워는 60대 여자를 제외한 남녀 모두 북경, 서울, 동경시민의 순으로 높았으며, PWC75%Hrmax는 남자 40대 와 여자 30대를 제외한 모든 연령 대에서 서울시민이 동경시민 보다 높은 경향을 나타냈다. 한편 모든 피검자를 대상으로 연령과 脚筋伸展파워와의 회귀식은 남녀 각각 Y=-0.30X+28.88(n=230, r=0.61, p<.001), Y=-0.l0X +12.49(n=611, r=0.32, p<.001), PWC75%HRmax와의 회귀식은 남녀 각각 Y=-0.01+ 2.50(n=116, r=0.29, p<.01), Y=-0.l0X+1.89(n=461, r=0.20, p<.001)이였다. 따라서 30~60대 서울시민의 체격 및 脚筋伸展파워는 북경시민 보다 낮게 나타나 삶의 질 향상을 위해 보다 적극적인 사회체육 활성화 방안 마련이 요망된다. The purpose of this study was to serve as a basis for making a health promotion policy for better quality of Korean life, by examining 313 citizens of Seoul's physical and leg extension power, physical working capacity who were in their thirties to sixties, enjoying good health, and by making a comparison of tile result with that of 509 citizens of Tokyo and 160 citizens of Peking who lived in different culture and living environment. The findings of this study were as below: First, the male citizens of Peking, who were in their forties to sixties, and the female citizens of the same city, who were in their fifties to sixties, were significantly higher in height, body weight and body mass index. Second, the male citizens of Peking, who were in their thirties and sixties, and the female citizens of the same city, who were in their thirties to forties, were significantly lower in heart rate in walking in the treadmill(90n/min). And there was a tendency that the citizens of Peking showed a higher ratio of stride to height. Third, the male citizens of Peking, who were in their fifties, and the female citizens of the same city, who were in their thirties to forties, had a significantly better leg extension power. As a result of examining all the subjects, there was a negative correlation between leg extension power and age. Fourth, all age groups of Seoul citizens, except males in their forties and females in their thirties, fended to be better in PWC75%HRmax than the citizens of Tokyo. When all the subjects were examined, there was a negative correlation between PWC75%HRmax and age. Consequently, there was a need to prepare more active plan to step up sports fur all successfully in order to improve the quality of life, as the citizens of Seoul who were their thirties to sixties appeared to be inferior in physical physique and leg extension power to the citizens of Peking.

The existing daylight analysis systems using computers are system independent, which means each system constructs own data for the daylight analysis in a separate way, and the data and information exchange between systems is not possible. If a single case of daylight analysis is compared, analyzed and evaluated in different systems, each system will repeat unnecessary process of producing, constructing and analyzing the same data. This causes a waste of resources and expenses in these works, and interferes with accurate, clear comparison and evaluation of the results owing to the possible errors and mistakes in the process of producing and constructing the data needed in each systems. Accordingly, this study aimed 1) to develop "Common Data Model & Analysis Module" for Daylight Analysis in order to share, exchange, analyze data between various systems that are operated independently, Also 2) aimed to consider the future extensibility of those applications on the web. And 3) aimed to propose this "Common Data Model & Analysis Module" as a prototype & protocol standard for daylight analysis system.

To study the relations of underground/surface-water exhaustion and excessive pumping, we have analyzed river, geological characteristics, recharge rate of rainfall and underground-water level. The ground water recharge rate from the SCS-CN analysis is 8.4%, and the recharge is computed in 6.4111 x 10^(5)㎥/y. This results mean that a big drawdown in observation holes may be occurred by excessive pumping. From in-situ hydraulic conductivity test, hydraulic conductivity in basement of the study area is calculated in 7.996 x 10^(-6)-2.067 x 10^(-6)m/sec. The underground/surface-water in the study area with small underground-water recharge rate will be exhausted by long time pumping.
