Myanmar is located in the south-east Asia peninsular and it is flanked by five neighboring states: Bangladesh, India, China, Laos and Thailand. It is located 10~22 degree north latitude, to 92~101 degrees east longitude. Myanmar has a tropical climate with three seasons in Myanmar. Hot season (March through April), rainy season (May through October) and the cool season (November through February). The coastal regions can get very hot and humid, especially before the rainy season. Myanmar has a monsoon season from May to October when there are heavy rains and often flooding. The investigation was carried out during the dry season(2013) in Nat Ma Taung National Park and Popa Mountain Park. Popa Mountain Park is located in Kyawpadaung Township, Myinchan district, Mandaly Division. The area is 49.63 square miles. Its coordinates are 29°31'60" N and 27°43'60" E. Nat Ma Taung National Park, Myanmar treasure is in Mindut District of Chin State and its area of 279 square miles. It is the third highest mountain in Myanmar with the height of 10,500 feet. Its coordinates are 21°14'00" N and 93°54'00" E. As the result, butterflies(Lepidoptera) collected in the two regions were about 60 species of 7 familys. Collecting dates, expedition activities, photo of main specimen and information of Myanmar were provided.

박상익,윤의수,김종균 공주대학교 사범대학 과학교육연구소 1995 과학교육연구 Vol.26 No.1

제 4차 교육과정 이후 제 5차 교육과정으로 개편되면서 생물 교과서에 유전 공학 개념 및 응용면이 더욱 강조 되었고, 제 6차 교육과정에서는 더욱 심화된 내용이 소개될 것으로 본다. 특히 일본의 고교 생물에서는 유저너 공학에 관한 내용을 학생들이 실험 할 수 있게 수록되어 있다. 그리고 앞으로의 자연과학은 유전공학 분야에서도 눈부신 발전을 가져올 것으로 기대되면 이에 맞추어 고등학교에서 유전공학 개념의 이해를 위한 유전자의 삽입, 형질 전환, 조직 배양 등의 실험을 실시하는 것은 학생들에게 많은 흥미와 관심을 갖게 하며 탐구력 신장에도 도움을 줄 것으로 생각한다. 본 연구는 제 5차 교육과정에 따른 고등학교 생물 교과서에 소개된 유전공학 내용을 분석한 결과 및 잎 절편체가 모상근으로 형질전환되는 기초 실험의 결과를 토대로 다음과 같은 결론을 내리고 탐구적 생물교육 자료로 삼고자 한다. 1.Agrobacterium tumefacieus, Agrobacterium rhizogenes을 이용한 모상근 발생에 관한 기초 실험의 특징은 형질전환체를 가시적인 뿌리로 얻을 수 있어 관찰이 용이하다. 2.형질 전환이 되었음을 GUS 활성 검사에 의해 쉽게 증명할 수 있어 유전공학 개념 도입을 위한 실험으로 고등학교에 도입하는 데 어려움이 없을 것으로 본다. 3.실험에 이용한 균은 감염 부위에 모상근을 형성하는 이외는 다른 병증을 나타내지 않기 때문에 대외적인 문제 없이 학교의 실험실에서도 취급할 수 있다. 4.유전 공학 실험에 필요로하는 화합물은 일선 학교에 대부분이 준비되어 있으며 kanamycin, Claforan은 미량 필요한데 쉽게 적은 비용으로 구입할 수 있다. 5.실험 기구는 간이 배양실만 고안 사용하면, 고등학교에 준비되어 있는 기구를 이용하여 해결이 가능하다. 유전 공학에 관한 실험을 하는데 실험실의 환경 조건이나 다인수 학급에서 어려움이 있더라도, 학생들에게 실험을 통해 유전 공학 개념을 형성시키는 기회를 갖게하는 것은 매우 중요하다. 이렇게 하여 자연과학에 대한 흥미와 관심을 높여가는 것은 우리나라의 기초과학 발전에 도움이 될 것으로 본다. The concept of biotechnology and its practical application is much more emphasized in the fifth curriculum than in the fourths and further intensified contents are supposed to be introduced in the sixth. Especially highschool biology in Japan, the contents on the biotechnology are recorded for the students to experiment and the future natural science is expected to develop brilliantly in a field of biotechnology. Therefore, students' experiments on gene insertion, transformation, tissue culture and so on, for their understanding of biotechnology concepts, are thought to stimulate their curiosity and extend their spirit of inquiry. This study is meant as an teaching aid, and reaches the following conclusions on the basis of the results of the biotechnology contents introduced in the fifth highschool biology texts and those of basic experiments on the transformation from explant to hairy root. The characteristic of basic experiments on hairy root growth used by Agrobacteriurm tumefacieus, Agrobacterium rhizogenes is that the observation is easy, since the transformational object is a visible root. The experiments are likely to be introduced without difficulty for highschool biotechnology concepts, since the transformation is easily proved by the GUS activation test. The germs used in experiments don't cause other diseases except forming hairy roots in infected parts, so they can be treated in school laboratories without outside interferance. Almost all schools are equipped with the complex materials needed for biotechnology experiments and kanamycin and claforan, just a little quantity of which is needed, can be purchased at a low price. The instruments can be replaced with the preequipped ones in school, only the temporary growthchamber needs to be devised. Though there are difficulties in biotechnology experiments because of unsufficient condition in laboratories or classes made up of a large number of students, it is very important for the students to have opportunities to form biotechnology concepts through experiments. To promote curiosity and interest in natural science in this way can be helpful in national basic science development.

The (0.8BaTiO₃-0.1SrTiO₃-0.1MgTiO₃)+0.006Nb₂O5 ceramics were fabricated by conventional ceramic process. The dielectric property of specimen was investigated that the specimen was sintering temperature at 1,300℃ for 3hours and them annealed at 1,100℃ for 3hours in a atmosphere (air) to be painted on the surface with CuO paste. The results of the temperature and frequency are varied, the dielectric constant and loss tangent are unsuitable for BL capacitor. The dielectric constants were varied to be negative temperature coefficient(2,000∼3,000) in the temperature range between -10 and 140℃, the dissipation factors (tan δ) were some high(0.1∼0.3). It was not grain insulation, in cause of the some difficult to be annealed temperature with CuO paste and fired atmosphere. But, we have some different annealing temperature and fired atmosphere. it will be suitable BL(Boundary Layer)capacitor.

나춘균,강상균,박희주,김의한 순천향대학교 1994 논문집 Vol.17 No.2

An experimental study was carried out to compare the tissue reaction of nitinol with that of stainless steel. 0.5cm, 27 nitinol wires(A group) and 0.5cm, 27 stainless steel wires(B group) were inserted into the beneath back skin of each 54 white rat and examined for 8 weeks. 3, 5, 7, 10 days, and 2, 3, 4, 6, and 8 weeks after the insertion, 6 rats(3 nitinolinserted rats and 3 stainless steel-inserted rats) were sacrificed and examined to make emphasis on such microscopic points as 1) vascular proliferation 2) type of infiltrated inflammatory cells, 3) proliferation of fibroblasts and collagen 4) the thickness of the membrane surrounding implants and 5) epidermal growth factor reactivity. As a result, the vascular proliferation and fibroblastic and collagen proliferation appeared to be somewhat earlier in the A group than in B group and the thickness of membrane was slight thicker in A group than in B group at an early stage. However, the infiltrated inflammatory cells showed no difference between both A and B groups. The above findings suggested that formation of the granultion tissue appeared somewhat earlier in the A group, but there were no significant meanings on microscopic grounds between them. Insertion in both A and B groups reflected the most intense reactivity of EFG after 3-5 days. The results that the reactivity of EGF was more intense at the periphery of the membrane after 2-3 weeks in bath A and B group were given in that the production of fibroblasts and collagen were revealed chiefly at the periphery of the membrane adjacent to nitinol and stainless steel.

출혈성 소화성 궤양의 장기 재발률

심기남,정훈용,양석균,홍원선,박의련,박무인,김해련,민영일 대한소화기내시경학회 1999 Clinical Endoscopy Vol.19 No.2

Background/Aims: Bleeding from a peptic ulcer is one of the common and serious complications associated with the rate of reported mortality, which ranges from 5% to 10%. Endoscopic therapy is effective in controlling active bleeding and reducing the emer-gency surgery, the immediate mortality rate and the incidence of early rebleeding. But few recent studies have documented the long-term recurrent bleeding rate after discharge in patients with bleeding peptic ulcers. The aim of this study was to determine the long-term recurrent bleeding rate and factors predisposing to recurrent bleeding. Methods: Eighty-eight patients with bleeding peptic ulcers discharged after medical treatment between Dec. 1990 and Jul. 1992 were included in this study and retrospectively followed up with medical records and telephone interviews. The end point of follow-up was recur-rent hemorrhage, surgery for treatment of ulcer complication, or death. Results: By July 1997, retrospective follow-up was available in 76 patients. Recurrent bleeding occurred in 23 patients (30.3%) with bleeding peptic ulcers and the median follow-up period was 69 months (range, 1 ∼79 months). The estimated cumulative recurrent bleeding rate after 1, 2, 3, 4, 5 and 6 years was 11.8%, 14.5%, 19.9%, 24.2%, 27.2% and 34.2%, respectively. There was no difference between the recurrent bleeding group and the non-recurrent bleed-ing group according to age, sex, prior NSAIDs use, previous history of bleeding or pepticulcer, site of ulcer, stigmata of recent hemorrhage at initial examination, method of treatment and amount of transfusion. Conclusion: Recurrent bleeding occurred in one-third of patients with bleeding peptic ulcers after 6 years of follow-up and one-third of recurrent bleeders rebled within 1 year. The factors predisposing to recurrent bleeding in the long-term follow-up could not be found. Therefore, further studies designed to identify factors predisposing to recurrent bleeding are needed and the evaluation of Helicobacter pylori status in bleeding pepic ulcer is needed because Helicobacter pylori is an important factor of peptic ulcer recurrence.

이헌경,김승용,홍원선,민영일,정훈용,김해련,정성애,김석균,심기남,양석균,박의련,조문경 대한소화기내시경학회 1999 Clinical Endoscopy Vol.19 No.3

Background/Aims: Although some authors have suggested that sodium phosphate (NaP) is more effective than polyethylene glycol (PEG) in bowel cleansing, there has been no crossover study proving the superiority of NaP over PEG in bowel cleansing and patients' compliance. The aim of this study was to compare the two solutions for colonoscopy, PEG and NaP, through crossover design with regard to patients' compliance, cleansing ability and side effects. Methods: Thirty patients underwent two separate colonoscopies for colonic polyp(s) with PEG and NaP, respectively. Before and after bowel preparation, blood pressure, body weight, and serum biochemical parameters were measured in all patients. In addition, a detailed questionnaire was used to assess side effects and the patients' preference. The presence of bubbles, types of residual stool, and overall quality of colon cleansing were assessed by one endoscopist blinded to the type of preparation used. In each colonoscopy, two biopsy specimens were taken at rectum. Results: In the NaP group, but not in the PEG group, there were significant changes in several biochemical parameters including sodium (+3.0±3.0 mEq/L), potassium (-0.3±0.3mEq/L), calcium (-0.5±0.5 mg/dL), phosphorus (+3.9±2.2 mg/dL) and osmolarity ( +10.1±9.3 mOsm/kg) after bowel preparation. In addition, the degree of body weight change was greater with NaP (-2.2±2.3 kg) than with PEG (-1.2±2.0 kg) (p=0.06) and the formation of bubbles that disturb luminal observation was more frequently found in the NaP group (p$lt;0.01). There was no difference, however, in the type of residual stool and the overall quality of bowel preparation between the two groups and no significant mucosal change was noted after bowel preparation in both groups. Moreover, PEG was found to be more difficult to take than NaP (p$lt;0.05) and among the 30 patients, 26 (87%) preferred NaP, while only two favored PEG (p$lt;0.01). Conclusions: We conclude that NaP can replace PEG at least in patients with good general condition. Further studies to decrease the incidence of bubbles and to establish subgroups suitable for NaP are needed.
