This study was carried out to interpret hydraulic behavior and CO₂gas desorption in countercurrent packing tower which packed 50 mm plastic Hiflow-ring. The results are as follows: 1. To compare with conventional packing, 50mm Hiflow-ring could save energy because of low pressure drop under high load. 2. As relative error between calculated value and investigated value was less than 6% in the loading point and flooding point we found that we can predict results mathematically which occurres in the packing tower. 3. The unique magnituteds of packing which was used are as follows. C_(L) = 2.1×10^(-4), n = 0.787 so we can predict efficency which occurres.

External lyogels containing prostaglandin E₁ethyl ester(PGE₁-EE), a produrg of prostaglandin E₁(PGE₁) as a therapeutic agent for erectile dysfunction, were formulated to overcome the aqueous instability and enhance the percutaneous absorption. Lyogels of PGE₁-EE were prepared with ethanol (EtOH)/proplyene glycol (PG) cosolvent system as a vehicle, cineol as an enhancer, and hydroxypropylcellusose as a gelling agent. In vitro percutaneous absorption studies were performed to determine the rate of PGE₁ absorption through rat or hairless mouse skin. The permeability of PGE₁-EE lyogel with enhancer was 16-fold greater than that of lyogel without enhancer. Cosolvent produced 9-fold increase in percutaneous absorption. Pharmacodynamic effects of lyogels were evaluated in mature male cats in terms of intracavernosal pressure (ICP). Lyogles containing 0.01% of PGE₁-EE showed higher ICP compared to intraurethral preparation of PGE₁(1%) and enhancer-free control lyogel. The shelf-life (t_(10%) of lyogel at refrigerated condition (4℃) was calculated as 928 days, which is 4.2 times longer than that of control hydrogel. As a result, PGE₁-EE was formulated successfully to a lyogel system with a selective enhancer and cosolvent system for the topical delivery of PGE₁.

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.

백악질 골화성 섬유종은 가장 흔히 발생하는 섬유 골성 병소(fibro-osseous lesion)로서, 경계가 분명하고, 느리게 성장하는 팽창성의 양성종양이다. 임상적으로 하악골의 소구치와 대구치 부위에서 발생하고, 여성에게서 2배 정도 호발하며, 주로20대에서 30대 사이에서 발견된다. 백악질 골화성 섬유종은 섬유성 이형성증을 포함한 다른 섬유 골성 병소와 감별되어야 한다 백악질 골화성 섬유종의 또 다른 형태인 유년형 골화성 섬유종은 15세 이하에서 발생하며 빠르게 성장하고, 좀 더 골 파괴적인 양상을 보인다. 치료는 병소의 크기에 따른 절제술이고, 재발은 드물다고 알려져 있다. 본 증례는 우측 하악 견치의 미맹술을 주소로 내원한 12세 남자 어린이로, 백악질 골화성 섬유종으로 진단 후, 외과적 적출술을 시행하여 양호한 치유과정을 보이기에 보고하는 바이다. Cemento-ossifying fibroma of the jaws is well circumscribed, generally slow-growing, benign lesions which en-large in an expansile manner. Clinically, it presents as a slowly enlarging lesion commonly in the premolar-molar area of the mandible and only occasionally in the maxilla and other locations. It occurs twice as often in females and primarily in the 20 to 30 year age group. Differential diagnosis should be performed, preferably with other fibro-osseous lesions such as fibrous dysplasia. A faster growing and more destructive variant of cemento-ossifying fibroma sometimes occurs in patients under age 15 and is termed juvenile (aggressive) ossifying fibroma. Treatment is surgical removal with the extent depending on the size and location of the individual lesion. Recurrence is considered rare. A case involving a 12-year-old male patient with delayed eruption of right mandibular canine is discussed. Following an incisional biopsy, the histopathologic diagnosis established was cemento-ossifying fibroma. After the surgical enucleation of the lesion, no sign of recurrence was detected.

Owing to frequent heavy rain due to abnormal weather, the occurrence of pepper anthracnose has recently increased, which affects the supply and demand of pepper. As a result, the price of red pepper powder in 2011, for example, increased three times compared to the average year. Although anthracnose of pepper plants has been controlled by fungicides until now, it is important to develop new resistant cultivars because of the reduction of the labor force in rural area and occurrence of new anthracnose strains resistant to fungicides. National Institute of Horticultural and Herbal Science developed two pepper lines, ‘Wonye 100005’ and ‘Wonye 100006’ that are resistant to pepper anthracnose. These lines were developed by continuous selection of progenies from a cross between ‘Wonye AR1’, which were developed from interspecific hybridization and ‘TF68’. The anthracnose resistance level of the two lines was higher than that of commercial cultivars and similar to check varieties showing highest level of anthracnose resistance.

적절히 치료받지 못한 유치의 치수 감염은 치근단 주위로 확산되고 그 치근단 병소는 계승 영구치의 조기 맹출, 법랑질의 저형성이나 저석회화, 발육정지 등의 합병증을 야기할 수 있다. 특히 유치의 치근단 감염은 계승치의 변위를 야기할 수 있으며, 계승 영구치배의 위치변화는 선행 유치의 치수변성으로 인한 것이 가장 많다. 본 증례보고는 하악 유구치의 치근단 병소에 의해 계승치가 변위된 경우로서, 증례 1은 하악 우측 유구치 하방의 치근단 낭에 의한 계승치의 변위가 관찰되어 유치 발치 및 조대술을 시행한 후 obturator를 장착하였고, 증례 2는 하악 우측 제2유구치 하방의 치근단 농양에 의한 계승치의 변위가 관찰되어 유치를 발거하고 공간유지장치를 장착하였다. 본 증례를 통하여 하악 유구치 치근단 병소에 의해 계승 영구치가 심한 변위을 나타낸 경우, 적절한 치료를 통해 계승 영구치의 적절한 맹출을 유도할 수 있었기에 보고하는 바이다. Primary teeth and the permanent successor must be understood as interdependent units, where each one of them interacts with and depends upon the other. The spread of pulpal inflammation in primary teeth to the periradicular tissues can lead to early eruption, enamel hypoplasia or hypocalcification, developmental arrest of permanent successor. Also the periapical inflammation cause permanent tooth displacement in various direction. We describe here two clinical cases of displaced permanent successor caused by periapical lesion of mandibular primary molar in children.
