Sports functions in Korea have varied after 1988 Seoul Olmypic Games. Enjoying other people's praticing sports is the only function before, but the functions are expanding to not only people themselves praticing sports but also their enjoying a new compound sport containing the idea of leisure. Like this to meet this new need, a sport called Kyung-reun has been begun since 1994. And Kyung-reun cyclists amounting to about 190 are attending at the new sport now. There are many studies about the physical condition and strength of amateur cyclists but a study of kyung-run cyclists on that field has not been done yet. Through testing the physical condition and strength of 43 kyung-reun students, who were picked up by Kyung-reun training school in 1995, I came to know which part they are showing superior or inferior in their physical strength that is different from one another in accordance with the peculiarities of their physical strength. And so with this study, I would like to make a little contribution for Kyung-reun cyclists to raise their racing ability by presenting conclusions, which are gained from making 5 grouping estimatation of physical strength as a basic material of exercise prescription for scientific training of physical strength. 1) Among exercise organs in the body, first, right girip strength in muscle strength was investigated that very-poor is under 40.52kg, average is ranged from 46.07kg to 51.61kg, and very-good is over 57.16kg. In right arm strength, very-poor is under25.88kg, average is ranged from 32.13kg to 38.36kg, and very-good is over 44.61kg. In right leg strength, very-poor is under 56.28kg, average is ranged from 64.18kg to 72.08kg, and very-good is over 79.98kg. On the contrary about left leg strength very-poor is 50.94kg, average is ranged from 61.28kg to 71.62kg, and very-good is over 81.96kg. In back strength, very-poor is 125.56kg, average is ranged from 141.48kg to 157.40kg,and very-good is over 173.72kg. In push-up, which is an indication of musle persistance power, very-poor is 27.70 times, average is ranged from 39.87 times to 52.03 times, and very-good is over 64.20 times. In sit-up very-poor is 25.48 times, average 28.53 times to 31.57 times, and very-good over 34.62 times. In sargent jump, an indication of muscle power, very-poor is 34.00 to 50.60cm, average 55.01 to 58.00cm, and very-good 61.81 to 72.00cm. In the case of side-step, an indication of quickness, very-poor is 42.58 times, average 42.59 to 45.90 times, and very-good over 52.56 times. In systemic reaction time very-poor is over 349.65sec, average 323.45 to 297.25sec, very-good under 271.05sec. In toe touching, an indication of flexibility, very good is 11.91cm, average 16.97 to 60.96cm, very-good over 27.09cm. On the other chest and leg raising very-poor is under 48.03cm, average 53.09 to 60.96cm, very-good over 68.81cm. In 7.7second-running, an indication of running power, very-poor isunder 51.70m, average 55.83 to 59.95m, very-good over 64.08m. In 41second-running, very-poor is under250.87m, average 265.27 to 279m, very-good 294.09m. 2) In respiratory circulation system it was investigated that very-poor is under 47.64ml/kg/min, average 52.21 to 56.77ml/kg/min, very-good 61.34ml/kg/min. 3) In nerve reaction test it was also investigated that in adoption ability very-poor is under -0.01, average 1.00 to 1.9, and very-good 2.00 to 2.99. In judgement ability very-poor is over 1.00, average 0.79 to 0.60, and very-good under 0.39. In precision very-poor is under 4.99 and over 5.00, average 3.99 to 3.50 and 1.00 to 1.99, and very-good 2.50 to 2.99. Andin emotion stability very-poor is under 0.49, average 0.70 to 0.79, and very-good over 0.90.

Mechanical vibration modes of the vibrating screen affect the fractional separation efficiency of any given screens which are used to classify the sizes or shapes of particulate matters concerned. Even though there are many parameters influencing on the performance of the given screen separators, in this study, the effective vibration speeds of the screen are selected as the main variable in the screening separation of particulate matters. The sample materials are glass beads in the particle size range of 100 to 900㎛. The cut size opening of the test screen is 600 ㎛. The other operating variables of the vibrating screen used are fixed. Fractional separation (Grade) efficiency curve(i.e., classifier selectivity curve) will be drawn to compare the effect of vibration speed of the inclined vibrating screen. And also the model of the probabilistic approach proposed by other investigator(subashinghe) will be tested on the screening data observed in this work.

This reseach has shown as follws: with the activity of original physical training program, many drivers have brought the effect of physical exercise in physiological ways and of the health consciousness, the reality of physical strength in self-conscions ways throughout enquete investigation. 1) The result of enquete investigation. Many drivers said that 17.2percent out of them are in bad health and 28.5percent out of them are in good health with regard to their health and the consciousness of physical training activity. 48.30percent out of these drivers don't take a exercise before driving and 52.90percent out of them do a exercise regularly. So 92.90percent among them said that it is necessary to participate in sports activity and 50.30percent among them said, "participating in sports activity makes them remove stress and promote their physical strength." Many drivers said that places and facilities are obstructive factors of sports activity. In order to improve the sports activity they demanded that it is essential to develop of physical exercise program and to take public relations. 2) The result of a subjective symptom and illness about drivers. Most drivers have something wrong with their bodies. 83.70percent out of them are ill in health, such as fatigue, neuralgia, lumbago, a gastroenteric disorder, hemorrhoids, constipation. Especially 32.30percent among them are a gastroenteric disorder and 11.40percent are inflammation of a joint. They said that there seems to be varions symptoms including inllness: lumbago, confirmed fatigue, transformation of the waist. They also feel that there are headache, the fatigue of eyes, lumbago as a subjective symptom after driving. 3) The effect of physiological function before and after doing a exercise in their shape drivers must be reduce fat under the skin and also decrease the abdominal region and the thigh parts. There appears effective part in bodies, that is leg strength(P<0.01) and arm strength(P<0.05) through factors of function of physical exercise.

Ken-Flote의 부유 선광법으로 정제된 미세한 석탄입자의 탈수법에 대한 실험적 연구가 진행되었다. 이 탈수 연구는 진공 및 압력 여과 장치를 이용하여 첨가제의 사용 유무에 따라 고찰되었으며, 실험 변수로는 압력, 여과시간, 케익두께와 현탁액의 pH였다. 또한 계면활성제 및 응결제와 그것들의 혼합에 따른 케익의 수분 변화량과 진공과 압력을 동시에 적용함으로써 케익의 수분 함유량을 고찰하였다. 총괄적으로 슬러리의 여과는 높은 압력, 긴 여과시간, 낮은 케익두께에서 적은 수분 함유량을 보여주었고, 첨가제의 사용에 따라 미세한 석탄 입자의 탈수를 효과적으로 진행시킬 수 있었다. 하지만 계면 활성제와 응결제를 혼합하여 첨가제로 사용하였을 때는 케익 수분 함유량 변화에 단지 미세한 감소만 초래하였다. 진공과 압력 여과를 동시에 적용하였을 경우는 압력 여과만을 사용하였을 때 보다 더욱 적은 수분 함유량을 보여주었다. 진공과 압력 여과에 대한 공정비는 각각 $1.75/ton과 $5.00/ton으로 산출 되었다 An experimental study of the dewatering of fine coal obtained with the 'Ken-Flote' column was conducted. The dewatering study was conducted with and without additives using laboratory vacuum and pressure filtration devices. The variables studied included the driving force, filtration time, cake thickness and slurry pH. The effects of surfactants, flocculants and their combinations on final moisture content of the filter cakes were also examined. Overall, it was found that the filtration of the slurry was enhanced by higher applied pressure, longer filtration time, lower cake thickness. Also, in general, it was found that the use of additives improved the filtration behavior of the fine coal slurries. It was observed that a combination of surfactant and flocculant provided only marginal improvement in filter cake moisture reduction. Split dewatering using both vacuum and pressure simultaneously provided less cake moisture than that obtained using pressure alone. The operating cost of vacuum and pressure filtration was estimated to be $1.75/ton and $5.00/ton, respectively.

To investigate the actual conditions and effect of physical exercise precription to be operated to middle and advanced age who participate in sports-school, first of all in both psychological and self-conscious aspect on opinionnaire and physical faculty are correlated, and by being operated physical exercise prescription in sports-school, this study obtained the following consequences. 1) Research on both psychological and self-conscious symptoms obtained following consequences. Related to recognition on social physical education, ordinary person needs social physical education and coach. Reason why ones participate in social physical education is to preserve and promote ones' health and physical strength, responsors present lack of space and facilities to exercise as obstructive factor against participation in social physical education. And generally ordinary person participate in badminton or swimming, amplification of space and facilities are pointed out as urgent problem for activation of social physical education. On satisfaction with ones' participation in social physical education, most of responsors satisfied it. Responsor answered that most of them is exercised in the P.M. without having dealings with a day of the week. And most of them answered that he perceives the lack of exercise before participation in social physical education. 2) Effect of exercise in sports-school is as followed. After being engaged in sports-school, health and conditions of physical strength are promoted, and concretely physical strength and flexibleness are promoted. Most of responsors answered after engaged in sports-school that he obtained vitality, and that they became to be joyfull in personal relations and mental aspect. 3) Physiological effect by physical exercise prescription before and after training is as followed. In the case of men, in physiological aspect, externally the weight lose (P<0.01), and internally exercise faculty and breathing circulation function are promoted. In the case of women, in the externally aspect, the weight and the subcutaneous fat get smaller. Related to exercise faculty and breathing circulation function good changes in all clause of research is showed after training, and particularly changes in back strength(P<0.01), arm strength flection(P<0.01), and systemic reaction time(P<0.05) is remarkable.
