It would be necessary to reorganize the system of College of Agriculture to solve these problems. The objective of the study is to construct the direction of reorganization of College of Agriculture in Sunchon National University. For the objective, survey composed of all professors in the Agricultural College and discussions among committee members were adopted. Survey data was collected and analysed. Through the study, reorganization strategies were built as the point of change of college name, administration of school system by unifying departments with similar major area, basic directions in reconstructing the curriculum for the school system, and strategies for the growth of the College. 1) Name of College of Agriculture will be changed to College of Life and Resource Science. 2) College of Agriculture can be reorganized into six schools based on survey, and for more concrete reorganization, additional opinions must be gathered. Number of incoming student can be reduced for school system from 395 at present to 300 (24% reduction). Finely specialized major should be prohibited, but addition of departments or speciality of new research area can be allowed for the establishment of administration of school system. 3) In management of curriculum, foreign language and computer science should be reinforced as general course in the school system. Obligated lecture hours of professor should be reduced, which would enhance the quality of lecture, and offerring lectures with similar subjects should be restricted. Dual major system is going to be allowed. Team teaching and class separation for the same subject should be allowed for the enhancement of lecture quality. In curriculum revision process, committee of curriculum revision in College of Agriculture must be set up and gather opinios for better revision. The committee regulate the credits for the general course, control overlapping or similar subjects among the schools(majors), select lectures for team teaching and the way of class separation in the same subject. They also provide permitted limits of and the way of conducting dual major system. 4) For further growth of the college, the following items should be satisfied. With the limited number of faculties, concentrating facilities and research capability of the college into specialized area is needed to enhance the competitive power of the college. In this study, the committee agreed to select horticultural area in greenhouse as the specialized area. This will be achieved gradually by employing new faculty members with major in this area and conducting cooperative research among faculty members. An extension system to train farmers for the newly developed technologies in agriculture should be established. In this facility, farmers can exchange their experiences among them, and farmers and the university faculty members can conduct experiments to solve problems occurred in farming practices. The extension system consists of division of reasearch, education, advise, information in agricultural area, and diagnosis of pest and diseases. Annual budget of the college largely depends upon the budget from the Ministry of Education. With the limited budget, it is almost impossible for the college to invest into the area where college faculty members intend to for the farmers. Collection of a fund for the growth of the college is needed. This fund can be gathered either from the alumni, faculty members and students or by reinvesting the profit from experimental farm of the college. The system for the reinvestment of the profit from appendges of the college should be established. The condition of research should be improved. This can be achieved by employing full-time researchers as faculty members and reducing lecture load of professors. Building for the center of cooperative research and systematic installation of experimental facility and equipments might also be needed for the improvement.

Statement of problem : Successful osseointegration of endosseous threaded implants is dependent on many factors. These may include the surface characteristics and gross geometry of implants, the quality and quantity of bone where implants are placed, and the magnitude and direction of stress in functional occlusion. Therefore clinical quantitative measurement of primary stability at placement and functional state of implant may play a role in prediction of possible clinical symptoms and the renovation of implant geometry, types and surface characteristic according to each patients conditions. Ultimately, it may increase success rate of implants. Purpose : Many available non-invasive techniques used for the clinical measurement of implant stability and osseointegration include percussion, radiography, the $Periotest^{(R)}$, Dental Fine $Tester^{(R)}$ and so on. There is, however, relatively little research undertaken to standardize quantitative measurement of stability of implant and osseointegration due to the various clinical applications performed by each individual operator. Therefore, in order to develop non-invasive experimental method to measure stability of implant quantitatively, the resonance frequency analyzer to measure the natural frequency of specific substance was developed in the procedure of this study. Material & method : To test the stability of the resonance frequency analyzer developed in this study, following methods and materials were used : 1) In-vitro study: the implant was placed in both epoxy resin of which physical properties are similar to the bone stiffness of human and fresh cow rib bone specimen. Then the resonance frequency values of them were measured and analyzed. In an attempt to test the reliability of the data gathered with the resonance frequency analyzer, comparative analysis with the data from the Periotest was conducted. 2) In-vivo study: the implants were inserted into the tibiae of 10 New Zealand rabbits and the resonance frequency value of them with connected abutments at healing time are measured immediately after insertion and gauged every 4 weeks for 16 weeks. Results : Results from these studies were such as follows : The same length implants placed in Hot Melt showed the repetitive resonance frequency values. As the length of abutment increased, the resonance frequency value changed significantly (p<0.01). As the thickness of transducer increased in order of 0.5, 1.0 and 2.0 mm, the resonance frequency value significantly increased (p<0.05). The implants placed in PL-2 and epoxy resin with different exposure degree resulted in the increase of resonance frequency value as the exposure degree of implants and the length of abutment decreased. In comparative experiment based on physical properties, as the thickness of transducer increased, the resonance frequency value increased significantly(p<0.01). As the stiffness of substances where implants were placed increased, and the effective length of implants decreased, the resonance frequencies value increased significantly (p<0.05). In the experiment with cow rib bone specimen, the increase of the length of abutment resulted in significant difference between the results from resonance frequency analyzer and the $Periotest^{(R)}$. There was no difference with significant meaning in the comparison based on the direction of measurement between the resonance frequency value and the $Periotest^{(R)}$ value (p<0.05). In-vivo experiment resulted in repetitive patternes of resonance frequency. As the time elapsed, the resonance frequency value increased significantly with the exception of 4th and 8th week (p<0.05). Conclusion : The development of resonance frequency analyzer is an attempt to standardize the quantitative measurement of stability of implant and osseointegration and compensate for the reliability of data from other non-invasive measuring devices It is considered that further research i

The rapid mixing process for coagulation is a critical component in a water treatment plant. However, at the present time a detailed understanding of the rapid mixing by in-line mixer or generally accepted criteria for the design of in-line static mixer are not available. The aim of this work is therefore to improve the understanding of how the in-line static mixer works and how to better utilize it in coagulation process in water treatment. To investigate the performance of static mixer, coagulation experiments were conducted to compare the static mixer to the traditional backmixer under several coagulation conditions. Experiments were also performed to compare the coagulation efficiency of different mixing type of static mixer which were made using different flow rates and the number of elements equipped in a pipe. The static mixer performed better than the backmixer for all coagulation and mixing conditions tested. Especially, the static mixer was very effective in the surface charge neutralization, as showing higher reduction of negative charge with increasing mixing intensity. However, little difference was observed in the performance of the static mixer equipped with 2, 3, and 5 elements. Also, in a series of bench-scale studies of rapid mixing, the in-line static mixer performed better than the traditional backmixer for both adsorption and charge neutralization (A/N) mechanism and sweep coagulation mechanisms. Especially, the static mixer was more efficient at producing A/N mechanism conditions as a result of its fast and uniform dispersion of the coagulant.

The purpose of this study was to evaluate the efficacy of adding autogenous bone to the toothash-plaster mixture in the healing process of bone. Full-thickness round osseous defects with the diameter of 20mm were made at the calvarial bone of adult dogs (n=19) bilaterally, which were thought to be critical size defect. The right defects were repaired with the toothash-plaster mixture plus autogenous bone (compressed volume 0.3cc) and the left defects with only toothash-plaster mixture. At 2-, 4-, 8-, 12- and 20- week after implantation, dogs were sacrificed and evaluated the osseous healing of bony defects clinically, radiographically, and microscopically. The results were as follows : 1. At the clinical observation, the wound healed very well without any problem except severe swelling in the early period after operation. Slight depression was recognized at the both sides when the portions of cranial defect were palpated. 2. There were statistically significant differences between toothash-plaster mixture groups and autogenous bone added groups at the same period, and among the groups in the bone density of the digital radiograms (P<0.001).There was a tendency that bone density was increasing with time. 3. In light microscopic examination, new bone formation was more active in the autogenous bone added groups than toothash-plaster mixture groups at the early period after mplantation but there is little difference at 20-week after implantation. 4. In fluorescent microscopic examination, the fluorescent band could be observed at the area of active bone formation and the band was more distinct in the autogenous bone added groups then toothash-plaster mixture groups. 5. In transmitted electron microscopic examination, organelles such as rER, Golgi complex and secretory granule and osteoblast were observed. In summary higher volume ratio of autogenous bone is needed to improve the bone healing in that there is little difference between toothash-plaster mixture group and autogenous bone added group at the 20-week after implantation in spite of new bone formation was more active in the autogenous bone added groups than toothash-plaster mixture groups at the early period after operation.

목적 : 분만 진통중 중증의 태변착색을 보인 임신에서 신생아의 예후를 예측하는데 있어 태아 심박자궁수축 검사가 유용성이 있는지 연구하고자 하였다. 연구 방법 : 1996년 10월부터 1999년 6월까지 인하대병원 산부인과에서 분만한 출생아 4,623명중 중증의 태변착색이 있었던 130명을 대상으로 하였다. 분만진통 1기중 활성기동안 최소 30분이상 2회이상 태아 심박자궁수축 검사(Corometrics사 145)를 시행하여 반응성, 태아 심박수 감소, 심박동간 변이의 감소등을 분석하여 신생아의 예후와 비교하였다. 산모와 신생아의 임상기록, 태아 심박자궁수축 검사 기록을 후향적으로 비교분석하였다. 통계적 분석은 SAS 컴퓨터 프로그램으로 하였다. 결과 : 1. 총 출생아 4,623명중 중증 태변 착색의 빈도는 130예로 2.8%였다. 2. 중증 태변착색된 임신에서 산과적 특징은 초산모가 70%로 높은 빈도를 보였고, 수술적 분만 즉, 제왕절개술과 흡입 분만이 61.6%로 높은 빈도를 보였다. 3. 중증 태변착색된 임신에서 신생아 예후가 불량한 경우는 130명중 25명으로 19.2%였다. 4. 분만 진통중 비정상 태아심박동이 중증의 태변유출과 동반되었을 때 신생아 예후가 불량하였다(88%). 특히 만기 태아 심박동 감소와 심박동간 변이 감소가 중증의 태변 유출과 동반시 각각 87.5%와 78.6%에서 불량한 신생아 예후와 관계되었다(odds ratio 19.6vs 30.8). 결론 : 분만 진통중 중증의 태변착색을 보인 임신에서 태아 심박자궁수축 검사가 분만후 신생아의 예후를 예측하는데 많은 도움을 줄 수 있을 것으로 사료된다. 특히 만기 태아 심박동 감소와 심박동간 변이의 감소가 중증의 태변착색과 동반되면 고위험군으로 간주하여 적절한 치료가 이루어져야할 것으로 생각된다. Objectives : The purpose of this study was to investigate the efficacy of intrapartal fetal cardiotocogram for prediction of adverse neonatal outcome in pregnancy with thick meconium stained amniotic fluid during labor. Methods : This study included 130 pregnant women with intrapartal thick meconium stained amniotic fluid among 4,623 pregnant wemen admitted to the department of obstetrics and gynecology, Inha University hospital from October 1, 1996 to June 30, 1999. We analyzed the fetal heart rate(FHR) tracing at least two 30-minute segments whenever possible during the active phase of first stage. Neonates were considered to have adverse outcome if they were required oxygen support, had low 5minute apgar score($lt;7) and significant complications such as sepsis, aspiration pneumonia, seizure in first 24hours. These data were examined retrospectively the maternal and neonatal in-hospital chart, electronic FHR monitoring strips and recorded data. The data were analyzed by SAS computer program. Results : 1)The overall incidence of thick meconium stained amniotic fluid among total birth was 2.8%. 2)The obstetric characteristics in thick meconium stained pregnancies were high incidence of primigravity(70%) and operative delivery(61.6%) such as cesarean section, vacuum extraction. 3)The incidence of adverse neonatal outcome in thick meconium stained pregnancy was 19.2%. 4)The patients in whom abnormal fetal heart rate patterns accompany the passage of thick meconium had high incidence of adverse neonatal outcome (88%). Especially, late deceleration and decreased beat to beat variability were related adverse neonatal outcome(odds ratio 19.6 vs 30.8). Conclusion : We suggested that intrapartal fetal cardiotocogram was one of the useful methods for prediction of adverse neonatal outcome in thick meconium stained amniotic fluid. Especially, late deceleration and decreased beat to beat variability accompany the passage of thick meconium was considered high risk conditions and required careful interventions.

Despite the current accomplishments with the repair of cleft lips, the surgical management of the nasal deformity remains a functional and aesthetic dilemma for patients, their families, and reconstructive surgeons. Recent improvements in the understanding and technical execution of te primary cleft lip repair have significantly reduced secondary sequelae and the consequent need for secondary surgical correction. But, secondary surgical corrections are necessary according to numerous factors. Such factors include the secondary surgical corrections are necessary according to numerous factors. Such factors include the severity of the initial deformity, the surgical plan, precision of execution of the primary repair, and success of the postoperative management. We preformed the secondary correction of cleft lip and palate in 11 patients via various methods. In conclusion, primary repair of cleft lip and palate patients is the most important to prevent the secondary deformities, and most of cleft lip and palate with secondary deformities must be treated with combined cheiloplasty and rhinoplasty.

The present study was carried out to investigate the potential acute toxicity of safflower seed by a single oral dose in ICR mice. Twenty animals of each sex were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, and 2,500 mg/kg bodyweight. Mortalities, clinical findings, and body weight changes were found and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects in clinical signs, body weight, and gross findings at any dose tested. The results showed that the single oral administration of safflower seed did not cause any toxic effect at the dose levels of 2,500 mg/kg in rats and the minimal lethal dose was considered to be over 2,500 mg/kg body weight for both sexes.
