Statistical cost models can provide construction cost quicker and more reliable than traditional ones if the collected cost data are sufficient enough to analyze the trends of the variables, such as the cost, shape, height, total floor area, or other variable of apartment housing projects. The reliable and explainable construction cost can be estimated at the early stage by using the actual cost data analytically and systematically. Although many scholars have made researches in the cost modeling techniques, they have difficulties in developing a computerized system due to the following problems. (1)Updating cost database periodically with the addition of actual cost data (2)Rebuilding cost models subsequently with the updated cost data (3)Proving the practical validity of the models The objective of the study is to provide a methodology for developing a system to improve the above problems and estimate more reliable construction cost with the past data of apartment housing projects. The proposed methodology is implemented into a computerized system with which each participant makes an estimate for her or his own goal.

서국웅,이미경,손승 釜山大學校 附設 體育科學硏究所 2007 體育科學硏究所 論文集 Vol.23 No.2

본 연구는 초보자와 지도자들에게 남자선수들의 어프로치투구동작에 관한 3차원적 각 분석에 따른 연속 투구동작의 기초 자료를 제공하는데 그 목적이 있다. 이를 위해 P광역시 소속 전국체전 메달리스트로써 남자선수 2명을 대상으로 하였다. 각 이벤트별 몸통 기울임과 상지관절(오른 어깨, 왼 어깨, 어깨 회전, 어깨 상하 경사, 오른 팔꿈치, 왼 팔꿈치, 오른 손목 및 왼 손목)각도를 분석한 결과 다음과 같은 결론을 얻었다. 선행연구와 비교하여 볼 때 E1에서 E5로 진행됨에 따라 몸통기울임 각도는 E3, E4, E5로 갈수록 점점 각도가 낮아지고, 오른 어깨 각도는 E1에서 E4로 천천히 낮아졌으며, 어깨 회전 각도와 어깨 상하 경사 각도는 E2 E3 E4로 진행 할수록 특히 E3에서 낮은 각도의 급격한 변화를 보였다. S1과 S2의 왼 어깨 각도와 왼 손목 각도가 E3과 E4, 그리고 E5에서 각각 다른 현저한 각도의 차이를 나타내는 것은 각 피험자 개인의 투구 폼에 따라 다르게 나타나는 것으로 사려 된다.

CAD 모델에 의한 마감물량 산출 시스템에 관한 연구

김선국 경희대학교 산학협력기술연구원 1996 산학협력기술연구논문집 Vol.2 No.-

Although the efforts to extract construction materials from the CAD drawings have been exerted over years, there have been difficulties in developing a practical system due to the several problems: the building modeling concept which takes the subsequent estimate into account; the material taking-off method; and the database management. In this paper, a methodology that efficiently links the estimate concept by the take-off sheet with a CAD design model is proposed to solve the above mentioned problems which give the inefficiency to draftsmen and estimators. The proposed ideas are implemented to be operated on the personal computer and proved highly effective in the management of databases and the material taking-off for residential areas.

The purpose of the study was to determine whether a 15.6mg.Kg ??' does of glutamate given one hour prior to incremental exercise test would reduce the lactate formation. Five well trained cyclists served as subjects in this experiment which included a placebo and glutamate trial. The subjects initially work on treadmill 200m/min for 3 minutes and here increased the workload by 20m/min every 3minutes until exhaustion. Blood lactate were collected from finger-tip. Subjects in the glutamate trial showed significantly lower lactate formation during exercise then they did in the placebo trial. In both groups no significant difference was found on heart rate. During the recovery lactate and heart, rate were unaltered in either the glutamate or placebo trials. In summary, glutamate ingestion may reduce lactate formation resultly improvement of performance.

Vesicovaginal fistula is a distressing complication which may follow hysterectomy, prolonged labor, chemical cauterization due to uterine prolapse, radiation therapy and cervix cancer. The management of vesicovaginal fistula still remains controversial in regard to the type of approach and timing of repair but the classic opinion is to wait 3 to 6 months to allow the surgical inflammatory reaction to subside. We experienced 4 cases of vesicovaginal fistula which were as follows; Case 1: 51-year-old The vesicovaginal fistula, about 3.0cm in diameter, after laparascopic hysterectomy 15 days ago was repaired with interposition of a gracilis muscle flap via the transvaginal route. Case 2: 38-year-old The vesicovagianl fistula, about 2.5cm in diameter, after Cesarean section 5 years ago was repaired with interposition of the omental flap via the transabdominal route because she had been accompanied by an overian cyst. Case 3: 46-year-old The vesicovaginal fistula, about 2.5cm in diameter, after manual self abortion at home 30 years ago was repaired with interposition of fibro-fatty tissue in labia via the transvaginal route. Case 4: 43-year-old The vesicovaginal fistula, about 2.0cm in diameter, after prolonged labor 12 years ago was repaired with interposition of the fibro-fatty tissue in labia via the transvaginal route. There noted no complications or recurrence during the minimal 1 year follow-up.

This study was to analyze the effects of the training of mental concentration on the learning of mathematics. The assumption was to support that the higher the level of mental concentration the higher the achievements of mathematics. For the verification of the assumption were the following five questions listed. First, how can the trained variable of mental concentration be transformable into visual abilities for reading? Second, how can the trained variable of mental concentration be transformable into reading speed? Third, how can the trained variable of mental concentration be transformable into reading comprehension? Third, how can the trained variable of mental concentration be transformable into reading comprehension? Fourth, how can the trained variable of mental concentration be transformable into the higher level of mathematics learning? Fifth, how can the trained variable of mental concentration be transformable into the higher level of school achievements? Two matched groups of junior high school students were sampled for the experiment: One was experimental group for learning mental concentration program, and the other was controlled one. It took eighty-eight days to finish experiment. To the above questions were the answeres listed as the follows: For the independent variables manipulated was it showed that the posttest scores of visual performances focussed on reading were significantly higher than the pretest ones, that the posttest scores of reading speed variable were significantly higher than the pretest ones, and that in verifying the performance of experimental group the posttest scores of reading comprehension variable were not significantly higher than the pretest ones in controlled group. For the dependent variables was is showed that there were no significant differences of mathematics performances between the experimental and control group. And that there were no significant differences of academic performances between the experimental and control group. However, the three consecutive test scores of mathematics of experimental group were higher than the controlled one from the first sessions with treatment of mental concetration through the second to the third one without no treatment. It was concluded that there could exist the differences of learning and development rate in students' traits preformed in acedemic achievements when students were taught to learn mental concentration program designed for extra-curriculum.
