The purpose of this study is to fond out the expectation (class form, class method, class evaluation, and class environment) and satisfaction of Visually disabled students to physical education teacher. Here is a result of analysis according to their level of visual disable. 1.The expectation to PE teacher according to the level of disable. 1)class form (1)order movement (stand up, walking, greeting, changing direction, lining and formation.) Among male students, only perfect visual disabled students have strong expectation to PE teacher and the others (half disabled, high weak eyesight, medium weak eyesight, and low weak eyesight) have normal expectation. Among female students perfect visual disabled and half disabled students have normal expectation and others(high weak eyesight, medium weak eyesight, and low weak eyesight)have high expectation. We can make a conclusion that all visually disabled students have expectation to teacher in an order movement class. (2)Swimming class All students didn't expect anything, especially perfect disabled students strongly against it. (3)Judo, wrestling, Korea wrestling. All students have high expectation. Especially, female students have very strong expectation(over 90%) (4)Dancing (Traditional Korea dancing, other countries dancing, and creative dancing) All students (perfect and half disabled, high weak eyesight, medium weak eyesight, and low weak eyesight) have high expectation and over 85% student wanted it. 2)Teaching method (1)Teacher leading style Perfected disabled students have strong expectation in this class style and others have low expectation . (2)Student leading style Overall male students strongly against about this style and female students didn't want this style class and perfect disabled students have normal expectation. (3)unification style only perfect disabled students have normal expectation and others(high weak eyesight, medium weak eyesight, and low weak eyesight) strongly against about it. 3)Class environment Pefect disabled, high weak eyesight, medium weak eyesight, and low weak eyesight students have very high expectation of various books, many equipment, safety, and clean environment. 4)Class evaluation Overall students (Perfect disabled, high weak eyesight, medium weak eyesight, and low weak eyesight students) didn't want in the evaluation class. We know the fact that many visually disabled students have high expectation for P.E teachers. Especially, during dancing, and gymnastic class, they have very high expectation. But our real is not up to this. Various P.E material and strong economical supporting is needed to solve these problems through qualified teacher. According to the satisfaction difference study, the reason of difference satisfaction between sex, and economic level of the family is due to P.E class which is lack of understanding those problems between P.E program and students. To solve this problem, we must try to make a good program regard student's situation.

The purpose of this study is to estimate the implicit prices and consumers’ preference by attributes on Korean beef cattle ham using choice experiments. Main attributes are the country of origin, non-antibiotic certification, HACCP certification, addition of Korean agricultural products and use of natural colors. The implicit prices of each attribute and level for country of origin are estimated as KRW 919.0 for Korean pork, KRW 2,173. for imported beef and KRW 5,232.9 for Korean cattle beef. The other estimated implicit prices are KRW1,762.9 for non-antibiotic certification, KRW 577.5 for HACCP certification, KRW 57.9 for addition of Korean agricultural products and finally, KRW 572.9 for use of natural colors. This study is expected to contribute to the decision-making process of Korean beef cattle farmers by providing useful quantitative information on attributes and price that are related to consumers’ preference on Korean beef cattle ham.

Ranitidine의 해명十二指腸切片에 대한 cholinergic效果

沈英燮,金起星,趙台淳 成均館大學校 科學技術硏究所 1989 論文集 Vol.40 No.1

In this experiment, the effect of ranitidine which is histamine H_2-recepter antagonist, were studied in aspect of the relationship between acetylcholine and histamine in isolated duodenum strips of guinea-pig. At the same time, the effect of the inhibition on the acethylcholinesterase activity in human serum were examined and the experimental results was summerized as following. 1) Ranitidine showed the synergistic effect with acetylcholine in the isolated duodenum strip and this effect was blocked by atropine. However, both physostigmine and DFP induced the synergistic effect with ranitidine. 2) Ranitidine potentiated the contractability of DMPP while a little effect on the contraction response due to pilocarpine, serotonin, tetragastrin and PGF_2α in the isolated duodenum strip. 3) Clonidine showed the inhibitory effect of histamine and acetylcholine contraction response of the strip but ranitidine and cimetidine showed no effects on this preparation. 4) ID_50 of ranitidine and cimetidine on serum acetylcholinesterase was 4 x 10 exp(-4)M and 9 x 10 exp(-3)M, respectively. From the above results it was suggusted that ranitidine might have cholinergic effect in guinea-pig duodenum strips and this effect partially might be due to the cholinesterase inhibition.

The purpose of this essay is to pursue problems and to improve planning in Korea as a developing Country. The problems of planning are comparatively reflected upon theories of students of public Administration, also practically testified planning institution through examples in Malaysia, Pakistan, India and Thailand in developing areas, and for the developed areas the U.S.A. Britain, and West Germany. In Chapter I, the history of Korean planning and the general theories are described ; Chapter II deals with three points of problems; firstly, at the central level the problem is the duality of the central planning agency, Secondly, the present condition of departmental planning agency, and thirdly, at the local level planning of local government. The operational problems are considered in Chapter Ⅳ focused upon unbalanced character of planning and the disparity between planning and budgeting. Concludingly, in Chapter Ⅳ, some findings and improvemental devices are summerized as follows; Firstly, excerpt key industrial planning, the national planning is to be delegated to the local level, and in the evaluation process popular participation is to be realized. Secondly, it is essential to practise the planning planned for the attainment of desired results. Thirdly, the dual character of central planning agency should be gotten rid of immediately, and the prompt mutual communication among the central, ministrial, and local administration planning agencies should be realized. This will be possible if the planning coordination committee is reorganized, and the function of it strengthen. Fourthly, the Annual Basic Operation plan should be decided upon before the request for budget made by each agency is conveyed. The plan is to serve as guide line in drafting the request for budget. Lastly, the unbalanced character of planning is to be possible gotten rid of.

단축압축하에서 복수원형공이 암반의 역학적 거동에 미치는 영향(제2보) : 단축압축하에서 복수원형공의 강도 및 변형 특성에 미치는 영향 Effect of the Multicircular Holes on The Strength and deformation Properties of Rock Mass Under The Uniaxial compression

趙萬燮,金沂柱 全北大學校 1995 論文集 Vol.39 No.-

The study on the stability of cavity in rock and mechanical behavior of its surrounding rock mass provides the fundamental basis for developing underground space. When the isotropic rock contained the multi-circular holes under the uniaxial compression, we have been studies on the fracture properties of rock mass then the gradient changes were 8 steps to the compression direction, α=0°, 15°, 20°, 30°, 35°, 45° ,60°, 90° and the parameters were presented as follows: 1. 3 steps of hole diameter change : Ø = 3, 5, 7mmØ 2. 3 steps of displacement rate change. : C = 0.05, 0.1, 0.2mm/mm As a result of this study, even if parameters(change of hole diameter and displacement rate) influenced to the properties of fracture strengths, they influenced less then gradient changes.

There are many studies on the bond mechanisms between concrete and deformed bars in reinforced concrete structures. The mechanisms are consisted of 3 actions; These are, chemical adhesion, friction, bearing by steel ribs. In this study, the factors that affect the bond mechanism between concrete and deformed bars were investigated. Analytical modelings for F.E.M. were also studied.

불연속면을 갖는 암석의 역학적 거동에 관한 연구

趙萬燮,曺義權,金沂柱 全北大學校 1996 論文集 Vol.42 No.-

To construct a structure in rock, first of all, the mechanical behavior of the rock should be understood. Most of rocks in situ have contained mechanical weak planes which greatly influenced on the mechanical behavior of the rock. On this study, hard rock was used to investigate in influence of the weak plane on the peak strength and displacement behavior. The results were summarized as follows; 1. When the angle of a weak plane(α) was 30。, the lowest peak strength was appeared. And the peak strengths between 30。to 45。were increased with increasing angles of weak plane. But the anisotropy of peak strength by the angle of weak plane was not remarkable in the comparision with that of soft rock, Tuff. The reason is the influence of the angle of the internal friction of the weak plane. 2. Different from soft rock, the peak strength was higher α= 60。than 90。with the lowest rate of displacement (1㎛/sec) in case of hard rock. It shows that the peak strength of weak plane is chiefly influenced by coefficient of internal friction rather than cohesion.

한국에 도해하는 검은머리갈매기(Larus saundersi)의 월동 현황

이기섭,박진영,이재범,김학진,유정칠 경희대학교 한국조류연구소 1999 연구보고 Vol.7 No.1

검은머리갈매기(Larus saundersi)는 그 동안 생존집단이 약 3,000개체로 추정되어온 멸종위기의 종이나, 한국에서의 월동 개체수에 대해선 현재까지 알려진 바가 없다. 본 조사는 1994년에서 1997년까지 동계기간에 실시되었다. 조사기간 동안 1994/95년 겨울에는 548개체, 1995/96년 겨울에는 1,159개체, 1996/97년에는 2,140개체가 관찰되었다. 해마다 증가하는 것으로 되어 있으나 실제는 조사면적이 확대된 데 그 원인이 있는 것 같다. 1994/97년 동계기간 동안에는 8개 조사지역에서 최대 2,425개체가 관찰되었다. 남해안에서는 조사가 광범위하게 이루어지지 않았기 때문에 월동 개체수는 이 보다 더 많을 것으로 추정되며, 종합적인 조사가 이루어진다면 전 세계의 생존집단은 6,000개체 이상이 될 것으로 사료된다. 조사지역 8곳 중에서는 순천만과 금강하구, 만경강하구에 각각 최대 500개체 이상이 도래하여 이 지역이 검은머리갈매기의 중요한 월동지임이 밝혀졌다. 성조에 대한 유조의 비율을 보면 평균 14.8%이었으나, 조사시기에 따라 변동이 있었다. 중국 리아오닝(Liaoning) 지방에서 적색 표식한 2개체가 아산만에서 관찰되었다. 최근 한국에서 새로 3개의 번식지가 발견되었으나 한국에서의 간척사업으로 인해 본 종이 계속 감소할 위기에 처해 있어 보존대책이 시급하다. Saunders's Gulls Larus saundersi are the endangered species and the world populations of the species were estimated about 3,000 individuals. The breeding sites were known at several sites in China, and the wintering areas were known in southern China, Hong Kong, Vietnam, Taiwan, Japan and Korea. Recently, the number of Saunders's Gulls was rapidly increased in Kyushu province of Japan: about 1,000 birds wintering there. One of factors affecting on the increasing population of Saunders's Gulls in Japan may be due to the destruction of the wintering habitats of Saunders's Gulls in Korea. But the wintering population of Saunders's Gulls in Korea has not been reported by now. We surveyed during the winter season of 1994~1997, and counted 548 individuals in 1994~95, 1,159 in 1995~96, and 2,140 in 1996~97. The increasing population each year may be due to the increase of survey areas each year in Korea. The peak count obtained from 8 sites was 2,425 individuals during the winter season of 1994~97. The real wintering population of Saunders's Gulls would be more than 2,425 individuals, because we did not survey many parts of southern coast although most areas of west coast were surveyed. If we estimate the world populations of Saunders's Gulls on the basis of this study and a Japanese report made in 1996(4,387 individuals), the world populations of the species may be more than 6,000 individuals. Sunchon bay, Kum river estuary, and Mankyung river estuary are major habitats supporting over 500 individuls of the wintering Saunders's Gulls every year in Korea. The ratio of juveniles to adults was averaged on 14.8% in the wintering population of Saunders's Gulls in Korea. Two individuals tagged with red colour flags were found in Asan bay, indicating that some birds wintering in Korea bred in Liaoning province of China. Breeding sites were newly found in the three reclaimed salt marshes. The major habitats of Saunders's Gulls should be set aside for nature reserves for effective protection and management, and should be turned into Ramsar sites to protect Saunders's Gulls in Korea.
