This study was about the development of green high-efficiency condensing heat exchanger which does not need a technical importation from foreign country and is able to produce it by own technology. The efficiency of BAND A, SEBBUK was set more than 90 %, and CO and NOx emissions were targeted less than 50 ppm and 40 ppm, respectively. The pilot unit was made using a heat exchanger Benchmarking of developed countries, and the shape and the position of tube were adjusted to reduce CO and NOx emissions at the same time.

Recently, strict pollutant regulations of NOx emission and increasing awareness of the environmental damage stimulated interest in research to obtain useful information regarding CO and NOx reductions at the same time. In this study, Premixed flame was experiment to reduce CO and NOx emission level by heat exchanger location in which burner and first heat location distance(L₁) and first and second heat location(L₂) changed. To reduce the NOx emission, first heat exchanger location(L₁) was decided near the flame. After first heat exchanger(L₁) was decided for the optimal NOx emission(about 30 ppm), in order to decide the optimal CO emission(about 30ppm), seocond heat exchanger location(L₂) was tested and decided for several cases. Finally, the optimal location of heat exchanger for minimal CO and NOx emission simultaneously was determined and suggested.

표면 분석용 CAICISS 장치를 제작하고, He^+과 Li^+이온을 사용하여 장치의 특성을 조사하였다. 장치 분해능의 평가기준으로 이용할 수 있는 △T를 정의하고 Li^+ 이온을 사용했을 경우와 비교한 결과, He^+ 이온의 경우 △T/T=0.034, Li^+ 이온의 경우 △T/T=0.04로서, Li^+ 이온의 경우가 분해능이 약간 떨어짐을 알았다. 그리고 Ta, Al 표적시료에 대한 실험결과를 보정함수를 이용하여 계산값과 비교한 결과 잘 일치함을 확인하였고, 보정함수는 입사이온의 에너지와 표적원자의 질량에는 무관하고, 실험조건에만 의존함을 알았다. 또한 Si(100) 표면에 He^+ 이온을 입사하여 입사각에 따른 산란강도 분포 스펙트럼으로부터 CAICISS 장치로 표면 1~4 원자층의 Si 원자에 대한 기하학적인 배열을 확인하였다. CAICISS system for surface analysis is constructed, and characteristics of our system are investigated using He^+ ion and Li^+ ion. We defined the △T which can be used to estimate the resolution of this system, and compared the value for the case using He^+ and that using Li^+. As a result, the △T/T is 0.034 and 0.04 for He^+ and Li^+, respectively. We also confirmed that the results of experiment for Ta, Al target atom agree well with these calculated values using a correction function, and the correction function is found to be independent of the energy of incident ion and the mass of target atom, but dependent of the experimental conditions. And we investigated the geometric structure of Si atoms from the angular scan curve for the Si(100) surface.

Physical education, through a great variety of activities, helps man develop efficient motor skills, physical fitness, a positive self-image, and socially desirable behavior. This study was under-ground, school curriculum, types of physical activities and hobbies. The individual sports and Busan areas were selected for sampling. Most of the players fail to have anopportunity to acquire knowledge and attitudes necessary for succesful participation in the future social life because emotional, cultural and home education is usually neglected. They need lots of activities that include the appropriate ways of body weight and condition control, which will provide them an emotional stability. Such offerings are greatly important for the proficiency in activities of their own specialization in their schools and particuar events.

Physical education, through a great variety of activities, helps man develop efficient motor skills, physical fitness, a positive self-image, and socially desirable behavior. This study was undertaken to discuss the consciousness of individual sport players in terms of their family background, school curriculum, types of physical activities and hobbies. Most of the players fail to have an opportunity to acquire knowledge and attitudes necessary for succesful participation in the future social life because emotional, cultural and home education is usually neglected. They need lots of activities that include the appropriate ways of body weight and condition control, which will provide them an emotional stability. Such offerings are greatly important for the proficiency in activities of their own specialization in Korean National College of Physical Education.

Pineal germinoma is one of the most radiosensitive intracranial tumors and so recently a regime of radiotherapy combined with ventricular shunting was advocated. But not infrequently seeding through the subarachnoid space and shunting system was observed. We have experienced a pineal tumor, which was treated completely by irradiation following ventriculo-atrial shunt but without evidence of intracranial recurrence spinal metastasis occurred 16 months later. After myelography total laminectomy from L1 to L3 was performed and intradural tumor was removed. Histopathological diagnosis was germinoma. After wonud healing spinal axis irradiation was performed with symptomatic improvement.

Malignant meningioma is rare and its initial clinical course tends to be short but otherwise indistinguishable from that of benign meningiomas. And although it has been noted that many of them have propensities for invading the dural venous sinuses, the skull, and even extracranial tissues by direct spread, there seems little tendency for these to metastases. The chances of recurrence and eventual death are high in malignant meningioma. Recently we have experienced a case of malignant meningioma involving the right frontal bone and frontal lobe with infiltration to the adjacent structures.

The purpose of the study was to investigate the effects of learning the conscious structure of students who had attended in the 1977-1981 Korean National College of Physical Education. As the results of the study, conclusions were made as follows; 1. It should be replaced the classes which had been lost by the activity of plyers. 2. It is necessary to be culture for individual players emotion - cultural education because home education are usually neglected. 3. Students should be taught about thanks-giring mind owing to advatage of players. Therefore, in order to make excellent players and coachers, it is very important to be guided the school life and domitory, and school curriculum is administrated more effeciency because of refilling the foundamental learng course, finally, most of players shoul be educated to give his honors his country and society, and attituts for sucessful participation in the furture social life.

The purpose of this study was to make motor driven roller and to be determined the effect of motor driven roller for the effective training in cyclists. When the cyclists did not train track and road events because of weather and track condition, they could used motor driven roller for their training. Because speed controller equipped with the motor driven roller in accordance with his ability and events. The predicted effects could be obtained using motor driven roller as follows. 1. It is useful for self-experimental motivation to be obtained using motor driven roller in cyclists. 2. It is easy for the cyclists to perform the prescribed training program in accordance with his ability and events. 3. The effects were significant in track events, because of speed controller equipped with motor driven roller especially. 4. In terms of stability of motor driven roller got more stable than that of conventional roller, and the effects could be reduce psychological depression in cyclists. 5. The training methods in cyclists could be improved through using the motor driven roller.
