Organic nitrogen and mineral contents in so, forages and blood serum of beef cattle sampled in June-July and September-October in 1987 from 12 different pasture areas of Cheju island were determined and the results are summarized as follows: 1. The contents of all mineral studied were significantly different (p<0.01) between soils of different pastures sampled in June-July. and the contents of P, Mg, Fe, Na. Ca and Zn were significantly different (P<0.01) between soils of different pastures sampled in September-October. The contents of P and Ca were much higher in soils sampled in June-July than in soils sampled in September-October. but the contents of K and Mg were opposite to those of P and Ca. 2. N, P, Mg. Cu and Co contents of orchard grass sampled in June-July were significantly different (P<0.01 ) between the pastures, and K, Ca, Mg, Na and Co contents of orchard grass sampled in September-October were significantly different (P<0.01) between the pastures. Cu, Fe, Na, Cu and Zn contents were higher in orchard grass sampled in September-October than in that sampled in June- July. 3. Except for Mg, mineral contents of ladino clover sampled in June-July were different between the pastures, and N, Ca, Mg, Fe, Na and Zn contents were significantly higher in ladino clover than in orchard grass. 4. The contens of Zn and Fe in blood serum of beef cattle sampled in June-July were significantly different (P<0.01) between the pastures and the contents of K, Ca, Mg, Na and Co in that sampled in September-October were different between the pastures. No difference was found in serum mineral contents between beef cattle from different pastures. 5. Serum Co content (0.07ppm) in the cattle raised in lsidore was below the normal, Co deficiency being suspected. Serum contents of the other minerals were found to be normal in the cattle of all pastures. 6. Only Fe content was significantly (p<0.05) correlated between the content of forages and the blood serum(R=0.84).

Carbon Tetrachloride의 독성에 미치는 Chlorpromazine의 영향

양기천 제주대학교 1969 논문집 Vol.1 No.-

The author investigated the influences of Chlorpromazine(CPZ) on the acute CCl₄ toxicity by measurement of S-GOT, S-GPT activities and LD??. Animals used were healthy mice weighing 20-30g and healthy albino rabbits weighing 1.7-2.2kg. The LD?? was estimated by Behrens- Kaerher method and S-GOT and S-GPT activities by Reitman-Frankel method. The results obtained were summarized as follows. 1. The LD?? of CCl₄in control was 10.7ml/kg b. w. for grouped mice. When, however the grouped mice was pretreated with CPZ (5mg/kg.), it raised the LD?? of CCl₄as 14.0 ml/kg. (Table 1) 2. The activities of GOT, GPT in the rabbit blood serum pretreated with CPZ seemed to be increased slightly in comparison with them of CCl₄alone, but it was not significant. (Table 2,3, Fig. 1,2)

고사리 근경의 hot ethanol-water soluble fraction이 가토적혈구막의 Na-K-ATPase 활성도에 미치는 영향

양기천 제주대학교 농과대학 제주도축산문제연구소 1988 畜産論叢 Vol.3 No.1

The influence of the hot ethanol-water soluble fraction of dried bracken rhizome (bracken extracts) on the Na-K activated ATPase activity in the rabbit erythrocyte ghosts was investigated. Also the studies on the relationship between amino acids-activation and the bracken extracts-inhibition on the Na-K- ATPase were performed. The results obtained were as follows : 1. The activity of Na-K-ATPase in the red cell ghosts was inhibited by the bracken extracts. And the degree of inhibition in the 4 × 10^(-4)g% and B × 10^(-4)g% concentration of bracken exracts were significant (p<0.05) 2. The activation of Na-dependent ATPase activity was inhibited by the 4 × 10^(-4)g% of bracken extracts when the sodium concentration was increased gradually and the concentration of potassium was maintained constantly in the working medium. 3. The activation of K-dependent ATPase activity was inhibited by the bracken extracts when the potassium concrntration was increased gradually and the concentration of sodium was maintained con-stantly in the working medium. 4. The activation of Ca-dependent ATPase activity was inhibited by the bracken extracts when the calcium concentration was increased gradually and the sodium and potassium concentration was maintained constantly in the working medium. 5. The activation of Na-K-ATPase was produced when the amino acids containing a typical active group(NH_(2) f lysine, OH of threonine and imidazole of histidine) were added in the working medium. The bracken extracts did not ihibit those amino acids-activation of Na-K-ATPase. 6. The bracken extrats produced remarkable inhibitio on the Na-K-ATPase activity which was stimulated by a typical SH group of cysteine, when they were simultaneously added in the working medium.

사염화탄소(四鹽化炭素)의 독성(毒性)에 미치는 Chlorpromazine 및 Iproniazid의 영향(影響)

양기천,Yang, Ki Chun 대한수의학회 1976 大韓獸醫學會誌 Vol.16 No.1

In the sequence of carbon tetrachloride hepatotoxicity, increased serum levels of a number of enzymes have been demonstrated in experimental animals. These observations, therefore, have served to help in detecting hepatic injury. The serological influence of chlorpromazine (CPZ) and iproniazid on the acute $CCl_4$ poisoning was executed in this investigation taking use of 6 albino rabbits (around 2 kg b.w.) in each group. By measuring of blood sugar level (Nelson-Somogyi method), S-GOT and S-GPT activities (Reitman-Frankel method), the pharmacological effects of the drugs was evaluated setting pretreated groups against the control. The results obtained were summarized as follows: 1. The intramuscular injection of $CCl_4$ led to increase the blood sugar level in first 3 hours and, after that, to decrease reasonably. But CPZ-pretreated group showed a tendency of increasing in compare with the control, and iproniazid-pretreated group inhibited evidently. 2. In S-GOT activity, the increased level was induced by $CCl_4$ in control. And CPZ-pretreated group showed a increased level until first day and decreased rapidly. But this property inhibited inhibited significantly by pretreating with iproniazid. 3. Although a single dose of $CCl_4$ increased the S-GPT activity, the more increasing trend was observed in CPZ-pretreated group. But these tendencies depressed remarkably in the iproniazid-pretreated group. It seemed to be attributed not to defend the $CCl_4$ toxicity but to be suppressed the enzyme systems in the liver by iproniazid that the blood sugar level and serum transaminase activities was decreased significantly in pretreating with iproniazid.

濟大 學生生活指導의 改善方向 探索

玄惠慶,姜志勇,許鐵洙,梁奇千 濟州大學校 學生生活硏究所 1982 學生生活硏究 Vol.5 No.-

A. The necessity and purpose of the study Since 1960s the number of university and college students has increased due to the rapid industrial development which requires more technical and intellectual persons. Also the upward spreading effects of education with generalization of secondary education have increased the social demands of liberal education, which expedite university students' diversity and heterogeneity. Therefore, the problems of students are no longer those of school authorities, but expand into social and national problems. Recently most of university in Korea have put more emphasis on the rearrangement and reinforcement of Student Guidance System. Especially, in case of Jeju National University, taking into considerations the special geographical conditions far away from the Korean mainland, and transitional stage on which JNU was promoted to national full-university status, along with the unification of campuses, the more careful interests and efforts are required for student guidance. This study was conducted with a view to providing the opportunities of educational and social specialization of student guidance. The following are the purpose of this study: 1) To set up directions for student guidance which can carry out the role and function of the university. 2) To consider, in the aspect of education, the main factors which influence the problems of university students. 3) To find out the difference between the problems of students' demand and abilty and realities of guidance, by comparing and analyzing present guidance realities between universities. 4) To offer improvement directions for efficient student guidances. B. The scope and contents of the study 1) The problem of student guidance in view of the purpose and function of a university. 2) The fundamental viewpoint of guidance in university 3) A theoretical investigation for efficient student guidance 4) A root cause of student problems 5) The present condition and problems of student guidance 6) Improvement directions for guidance C. The method of the study 1) To analyze the domestic data as well as foreign data 2) To analyze the questionnaire 3) To analyze the results of guidance through the actual result reports of student guidance 4) To analyze various data of student guidance 5) To represent by percentage(%) the realities and problems of student guidance D. The problematic factors of student guidance in the light of purpose and function of a university 1) The original purpose and functions of university are the acquisition of knowledge the transmission of knowledge, and application of knowledge. They are based on the wholemen community of intellectuals in which research, education, and service are determined to be prime mission, but hasn't well been fulfilled because of the present special situations of Korea. 2) In the expectations of university's roles, it is becoming important to harmonize the real desire of administrative officials, intellectual desire of professors, and idealistic of students with each other. 3) A university's research function of creating academic atmosphere is very unsatisfactory. 4) The relationship between professors and students, and even among students hasn't well progressed because of excessive solicitude of omission by graduation quota system as well as full classes. And cultural education is not conducting effectively because it is very fragmentary and formal. 5) The chaos is being produced about the establishment of concept of community service given to university education, the ways and limitations of participation in society and actual world. E. The viewpoint of student guidance The contents and methods of student guidance are decided according to the view of students to be the subject of guidance. In the reformative viewpoint of student guidance by educative instruction methods, main method of guidance are authority, blind obediance, cramming, subjectivity, control, rectification. From the educative viewpoint of student guidance, self-direction can be possible by means of students' interest, desire and ability. Future student guidance must be conducted to develop their potentiality and natural ability of growth without external force or blind gramming. F. Following theoretical investigation were enforced in order to establish effective directions for student guidance. 1) The concept and purpose of the orientation for freshmen and its basic policy and contents 2) The necessity and contents of department arrangement guidance 3) The practice of alloted academic adviser system 4) The educational functions, necessity, and meaning of campus extracurricular activity 5) The role and function of student government(SNDC) 6) The welfare and scholarship system for students G. As a result of a selection of root causes of student problems from the introspection, the following were important order of immediate and expected problems 1405 freshmen; 1. Studies Problem(40.3%) 2. Course problem(36.4%) 3. Economic life problem(36.9%) 4. Social fitness Problem(26.7%) 5. Health Problem(16.0%) The investigation consequence for sophomore and junior are following; 1. A course Problem(35.2%) 2. Economic life problem(35.4%) 3. Human relation problem between professor and student(35.2%), and a good use problem of spare time(35.2%) 4. Studies problem(26.4%) H. The problems were revealed by a statistics which were investigated and analyzed realities of student guidance as follows, respectively: 1. In the orientation for fresh, it is emphatic to give only a information, the program of a important purpose in an orientation that are helpful to initiation of university life with a safety emotionally by withdrawing from strain from strange environment is making light of. 2. In the guidance of a department choice, department allocation by a record is making without giving a chance searching for self-characteristic like aptitude or hobbies, the guidance plan and materials of objectivity are not prepared, and the chance choosing carefully comes very short of. 3. In the management of partial charge professors system, the relation position between professor and student is very formal because, as a matter of fact, it is meaningfulness to guide students from a professor is responsible for guidance of so many students, director of professors are in want of the whole recognition about guidance contents. 4. Though the circle activities are very important as an educational function, a director professors of a circle has charge of guidance for so many students, the activities without purpose consciousness are unfolding, the activities with interest and recreation mainly are rich in, and the activities for enlightenment sound activity model which gets a value experience are situation insufficiency itself. 5. In the activities and management of Student Body, he is not accomplishing plan and function by nature, the activities and management individual and new are very lack owing to emphasis of events centre and actual results centre. And the appearance of making heteronomy now that he is not also chose relation to the circles in SNDC is more and more deepening. 6. The lower organization taking charge of students guidance specially in managent of the students guidance institute are in need, the number of specialists are for want of, it is just so formal to run the students guidance institute because the institute's finance is in very poverty, its originally functions are not accomplishing due to the consultation mood in consultation room is stiff. 7. Our university lacks in research facilities and mental incentive with regard to student welfare function. I. I am directing the way of student guidance for withdrawing from and getting rid of the problems revealing, concerning the students guidance to the best of his ability by the realities of students problems as follows; First, the investigation and research activities and assistance understanding and helping students have to provide in the side of prevention of problems by understanding university students' nature consciousness and characteristic regularly. Second, students' spontaneous participation, the development of interesting and useful programmes, and faculty members' active supports & guidance should be given to obtain effective result of fresh's orientation. Third, school authorities should provide freshmen with opportunity to judge their aptitudes from the time of entrance by holding orientation several times, and by offering detailed informations on the department selection. Fourth, The academic & human relations between professors and students should be maintained through proper enforcement of alloted academic professor system. Fifth, every circle and club should established proper and patent objectivities of activity, and try, to create and introduce useful and interesting programmes in order to promote an educational function of each circle and club. Sixth, in order to eleminate the gap between students and Students Government, students should take deep interests in Student Body's activity, while Student Body should develop academic and literary activity to promote students research activities. Seventh, in order to promote the function of Student Guidance Institute, there should be secured expert staff for smooth counselling, investigation and employment guide as well as financial and administrative support of school authorities. Finally, university authorities should organize several institute such as student welfare committee(institute) so that they might grasp what student opinions & desire are and make students lead comfortable campus lives.
