This study had the players(Basketball: 10, Baseball: 20, Football: 20, Total: 50 players) of K university located in Seoul as the subject and made a comparative analysis on the ball game players' characteristics of physique and physical strength. As a result, I've root the conclusion as follows : 1. Physique Among the measuring items on physique, in the chest, there was no significant difference between each group. The result of the mean depending on each factor, length, perimeter, weight appeared in order of basketball player〉baseball player〉football player. 2. Physical Strength Among the measuring items on physical strength, in a grasping power, a standing high jump and respiration rate, there was no significant difference between each group, and the result depending on each factor is as follows : 1) Muscular strength Among the factors of muscular strength, the grasping power appeared in order of football player〉baseball player〉basketball player, and the abdominal muscular strength appeared in order of basketball player〉football player〉baseball player 2) Muscular endurance The result of sit-ups which is a measuring factor appeared in order of football player〉baseball player〉basketball player. 3) Instantaneous promptness The test result of a standing high jump to measure instantaneous promptness appeared in order of baseball player〉basketball player〉football player. 4) Agility The test result of a jump step to measure agility appeared in order of football player〉basketball player〉baseball player. 5) Pliablity The result of the execution of trunk flexion to measure pliablity appeared in order of football player〉baseball player〉basketball player. 6) Endurance of the whole body Among the measuring factors of the endurance of the whole body, heart rate appeared in order of baseball player〉football player〉basketball player. In oxygen uptake per weight, the group of football players showed the highest mark in time of stability and of the maximum and the group of basketball players showed the lowest mark. The sustaining time of exercise appeared in order of basketball Player〉football player〉baseball player.

In this study, the compression type heat pump system using hot spring wastewater, as a heat source, from hotel with sauna was designed and analysed. This system for hot-water supply is composed of heat pump, hot water storage tank, wastewater storage tank, wastewater cleaning bed, etc.. The charging process of heat into the hot water storage tank is achieved only at night time using peak-off electricity. The system design was focussed not only to increase COP but also to use the peak-off electricity. TRNSYS was used for the system simulation and new component for the heat pump was made. As a result, it was forecasted that the yearly mean COP of heat pump is about 4.8 and heat pump can supply 100% of hot water load except winter season weekend. The important thing that should be considered is to decrease the temperature difference between condenser and evaporator during the charging process of heat pump.

測定의 起源에 대한 小考

白南渡 진주산업대학교 1970 論文集 Vol.4 No.-

The history of measurement is as old as that of human beings. They began measuring lengths and weights when agriculture and stockfarming were commenced. Then quantities continuum were measured as well as quantities discontinuum. The beginning of measurement was begun by comparing things each other, and the ways of direct comparing and of indirect comparing were adopted. Thereafter unit systems were socialized, and they were determined on the base of the decimal system, as the societies were gradually progressing, and simultaneously the metric system was created. Studies in details concerning every field of the unit systems follow.

Geometry is one of the subjects which were developed earlier than any other in the field on mathematics, and it has been the object of study of many scholars for thousands of years. Accordingly it has been developed into a wide range, and its logical basis was established lastely in a rigid criticism. As the relation between geometry and numbers is deep, the origin of numbers is described first. The knowledge and technique concerning geometry in ancient times can be supposed through Herodotus(B.C 5th century), the Greek historian's History, and the pyramids which are conjectured to have been built about 3,000 years ago, and geometry was put in order and completed later by the Greek's initiative. The relationship between numbers and geometry follows.

This paper is content analysis on the trend of study in PMIS. The purpose of study make anal-ysls on the trend of study in PMIS and propose the diretion of study and development on PMIS. The concept of MIS came out from private sector. The concept of PMIS Is application of MIS at the beginning. The scope of approach on PMIS extended following development of computer technology and change of environment. From the viewpoint of that, made a trial of conceptionalizatlon to en-large Integrated Public Management Information System(IPMIS ) in order to develop of the the-ory of PMIS. The analysis on the trend of study in PMIS is based on the concept of IPMIS as stated above. Analysis unit and catfory are following : ① division of study ② field of study ③ research method ④ purpose of study ⑤ type of era'mination ⑥ analysis level of emipirical research ⑦scope of time in empirical research ⑧ subject of study. On the ground of the analysis, the trend of study in PMIS are coming : ① Integrated ap-roach in PMIS is needed because approach on the PMIS focused on the process of PMIS. ②Empirical study and Integrated approach on the PMIS are needed. The direction of study and development on PMIS are following : ① Humanistic research and approach on the PMIS ② Integrated approach on the PMIS ③ aualitative approach on the PMIS. ④ Develop and practice of PMIS to reslove problems of Industrial society today. ⑤ Make a premise of national security and economic development on planning information- communica-tion network. ⑥ Found creative information- communication policy cope with new technology.

The definition of integral is that finite function for finite interval could be integrated. Next when in spite of heing finite in interval integral of infinite funcfcon and integral introducing integral concepts is distinguished with general integral, it is defined as transcase integral, extensive integral and pseudo integral. Though general integral is defined as a utmost limits of Rieman sum, pseudo integral is defined as a utmost limits of general integral

The wake flowfields behind 2-D wedge-type Karman vortex generators were experimentally studied in a wind tunnel at Red=1.89×103 and 3.78×103 to obtain basic data required for the optimal design of air-flow sensors (AFS) utilized in automotive systems. The wake generated by an isosceles triangular wedge became stabilized along the downstream direction slightly faster than those of by equilateral triangular wedges in a near wake region. The momentum thickness of the wake generated bur an isosceles model was slightly thicker than those of by equilateral models. It was revealed that the variance of Strouhal number vs. Reynolds number was not sensitive to the shapes of the wedge-type vortex generators. Strouhal number of the wakes behind wedge models was observed in the range of 0.205〈St〈0.215 and nearly invariant as the change of Reynolds number in the range of 6×102〈Red〈1×104.

Author has studied about dental needs on the 300 persons who were insurance patients and 300 persons who were non-insurance patients treated at the private dental clinic in Taegu city from Jan. 1. 1985∼to Dec. 31. 1985. 1. In insurance patients, female group was (55.33%) higher than male group(44.66%), but non-insurance patients, male group(54%) was higher than female group(46%). 2. By age distribution, the highest group was 20∼29age group, in insurance group as well as non-insurance group. Insurance group was 21%, and non-insurance group was 21.83%. 3. The highest of patients visiting time was one time both in insurance patients(43.66%), and non-insurance patients(46.33%). 4. Average visiting time was 2.2, in insurance patients and 2.4 in non-insurance patients respectively. 5. By distribution of chief complaint at first examination, A group was highest both in insurance patients(36%), and non-insurance patients(45.33%). The non-insurance patients group was more numerous than insurance patients group in A group.
