This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

Seit ersten Start eines koreanischen Flugzeuges im Rahmen der koreanischen Zivilluftfahrt im Jahre 1948 ist die Entwicklung des koreanische Lufttransports erraschend. Demzufolge kommt Sdkorea im Jahre 1999 im Rahmen der Lufttransportquantitt zum sechsten Land in der Welt. Dieser Erfolg wird sich in Zukunft noch erweitern, weil Su¨dkorea den gro¨ßten Flughafen von Asien Ende Mrz 2001 in Incheon ero¨ffnete. In diesem Zusammenhang ist nunmehr auf der Ebene der Entwicklung des Lufttransports in Korea zu erwarten, da eine Reform nach Vereinheitlichung der Regelung gewisser privatrechtlicher Fragen, die nit einer intemationalen Befrderung von Personen, Reisegepa¨ck oder Gu¨tern in Luftfahzeugen in Zusammenhang stehen, durch ein neues vereinheitliches Abkommen gela¨uft. Bekanntlich hat die International Civil Aviation Organization (ICAO) angesichts der Reformbedu¨rftigkeit und Unu¨bersichtlichkeit des Warschauer Abkommens ein neues Abkommen geschaffen, um das gegenwa¨rtig noch geltende Abkommenssystem zu revidieren und mo¨glichst durch ein neues vereinheitliches Instrument zu ersetzen. Na¨mlich, die sogenannte Montrealer U¨bereinkommen wird in Kraft treten, sobald 30 Staaten das bereinkommen ratifiziert haben undhiernach eine Frist von 60 Tagen abgelaufen ist. Allerdings bleibt noch in diesem neuen Abkommen des grundsa¨tzliche Konzept des urspru¨nglichen Warschauer Abkommens von 1929. Trotzdem steht im Mittelpunkt des U¨bereinkommens auch ein gegenu¨ber dem Warschauer System in verschiedenen Teilen abweichendes Konzept der dem Luftfrachtfu¨hrer obliegenden Haftung. Allerdings ist das zweifellos sinnvoll, weil es trotz seiner Ma¨ngel so doch eine vie1 gro¨ßere Rechtssicherheit und Vorhersehbarkeit gewa¨hrleistet. In Korea gilt den Haager Protokoll von 1955 seit dem Jahre 1967 fu¨r den internationalen Lufttransport. Obwohl das HP/WA von 1955 fu¨r die internationale Luftbefo¨rderung in Korea gilt, ist im Bereich der koreanischen Luftfahrt tatsa¨chlich die ABB von Fluggesellschaften und die Montrealer Zwischenvereinbarung von 1966 noch bedeutsamer. Somit ist es in Korea erforderlich, eine neu verwirklichte Vereinheitlichungsregelung im Rahmen des internationalen Lufttransports zu schaffen. Diesbezglich ist es auch notwendig, da die Schwerpunkte des neuen vo¨lkerrechtlichen Montrealer U¨bereinkommens von 1999 (CONVENTION FOR THE UNIFICATION OF CERTAIN RULES FOR INTERNATIONAL CARRIAGE BY AIR DONE AT MONTREAL ON 28 MAY 1999) aus der Sicht Koreas zur Untersuchung kommt.

Purpose : Several panoramic indices have been suggested to assess bone quality from the morphology and width of mandibular cortex on panoramic radiography. The purpose of this study was to compare dental implant failure group with control group in panoramic mandibular index (PMI), mandibular cortical index (MCI), and gonion index (GI) and to determine the effect of these panoramic indices on dental implant failure. Materials and Methods : A case-control study was designed. Test group (n = 42) consisted of the patients who had their implants extracted because of peri-implantitis. Control group (n = 139) consisted of the patients who retained their implants over one year without any pathologic changes and had been followed up periodically. They had dental implants installed in their mandibles without bone augmentation surgery from 1991 to 2001. The following measures were collected for each patients: 1) PMI, MCI, and GI were measured twice at one-week interval on preoperative panoramic views; and 2) age, sex, implant length, implant type, installed location, occluding dentition state, and complication were investigated from the chart record. Results : The PMI showed moderate level of repeatability. The intra-observer agreement of MCI and GI were good. There was statistically significant difference in PMI between two groups. There were significant different patterns of distribution of MCI and GI between two groups. Among the panoramic indices, PMI and MCI showed significant correlation with dental implant failure. Conclusion : Panoramic indices can be used as reference data in estimating bone quality of edentulous patients who are to have implants installed in their mandibles.

Today, endoscopy has revolutionized the practice of gynecology. It has modified the thinking, approach, diagnostic ability and operative capability of gynecologist, and make an enhancement of the skills of gynecologist far beyond anyone's expectations in parallele with the application of the ultrasonography. This revolution has been flourished with the in vitro fertilization(IVF), and further used without big problem during pregnant state. Modern optics and high-powered light sources are now efficient that the diameter of endoscope has been reduced without loss of definition. This has allowed the development of narrow telescope which can be inserted via a laparoscope into the ampulla of the Fallopian tube. Salpingoscopy is already providing a clear understanding of pathology in the tube. However, this brilliant apparatus and application have been blockaded totally by the medical insurance system in our country. This sorrowful happening makes a regression of medical development in Korea.

TThe results based on Toegye's thought of the body such as the above are as follows : 1.Toegye's thought of the body means Igi Theory(the theory on reason and energy). The above Toegye's thought of the body is based on Igi Theory(the theory on reason and energy). Human body based on I(reason) is made of Gi(energy), and then Yi Toegye maintains that a human should be himself as the master of action. 2. Toegye's meaning of the body based on Igi Theory(the theory on reason and energy) is made of Gi(energy) with the beginning of I(reason). Therefore the today's meaning of the body is considered as Some and Body. 3. Toegye maintains on the basis of his so called Igihobal Theory that since the mind and body of human being are inseparably related to each other, they are simultaneously generated, and that man thus exists as a mental and physical being with both of them. This view of the relationship between mind and body with the theory of psychosomatic units that human mind and body are in inseparable relation, which is today a viewpoint of body in Physical Education.

제주산 온주밀감을 이용하여 醱酵最適條件에서 얻어진 감귤주의 單式蒸溜하여 알콜농도를 43˚와 60˚로 조절한 다음 불란서산 참나무 술통재의 切片(1×1×3cm)을 浸漬 하여 熟成條件을 검토하였다. 알콜농도 60˚인 증류수중의 메탄올은 0.136g/100㎖, 알데히드는 4.07㎎/100㎖휴젤油는18.35㎎/100㎖, 에스테르는 27.03㎎/100㎖였다. 알콜농도가 높고 온도가 높을수록 참나무성분의 浸出이 잘 일어났으며, 단기간 熟成을 위해서는 다소 고온에서 熟成하는 것이 좋을 것으로 판단되었다. 숙성 pH는 4.1에서 색소침출효과가 좋았으며 자외선 처리효과는 없었다. 色素浸出은 온도에 많은 영향을 받고 있는 것을 알 수 있었으며, 官能檢査 결과 45˚, pH 4.1에서 6개월 熟成時에 외관 및 기호도에서 충분한 상품가치를 나타내었다. 감귤 브랜디의 경우 외국산 유명제품과 큰 차이를 보이지 않아 브랜딩기술의 확립과 熟成技術의 보완한다면 産業化에 대한 충분한 가능성이 있는 것으로 平價되었다. In order to produce citrus brandy made from Citrus unshiu produced in Cheju, aging conditions of citrus fine spirit with dipping oak chip were investigated. Citrus fine spirit prepared with simple distillation of citrus wine was adjusted to 43。 and 60。 alcohol concentration, and then three pieces of oak chip (1×1×3cm) was added to 300㎖ citrus fine spirit. The contents of methanol, aldehyde, fusel oil and ester were 0.136g/100㎖, 4.07mg/100㎖, 18.35mg/㎖ and 27.03mg/100㎖ respectively. The absorbance at 500nm of citrus fine spirit was increased with high alcohol concentration and high temperature. Color extraction from oak chip was mainly affected on temperature, and the effect of UV irradiation was not appeared. Compared with commercial Scotch whisky, citrus brandy adjusted to pH 4.1 and aged at 45℃ for 6 month was good in sensory evaluation.

Cycloheximide가 Mouse肝臟의 인산염 分解酵素의 活性에 미치는 影響

趙賢熙,鄭鎬三,李圭植 漢陽大學校 環境科學硏究所 1985 環境科學論文集 Vol.6 No.-

Cycloheximide는 Streptomyces griseus에서 추출한 항진균성 항생제로 진균의 성장을 저해하는 물질로 알려져 왔으며 포유동물의 세포에서 ribonucleic acid와 단백질 합성을 저해한다고 생화학적 방법에 의하여 보고되었다. 최근에 이르러 cycloheximide의 투여로 간세포내 소기관인 조면내형질세망 및 Golgi complex의 손상에 의해서 단백질합성이 저해된다고 형태학적으로 연구 보고된 바 있다. 이와같은 cycloheximide의 투여로 간세포가 손상을 입어 단백질합성이 저해될 때 간세포내 인산염분해효소로 분포되어 있는 acid phosphatase와 adenosine triphosphatase 활성을 추구하였다. 실험동물로는 실험실에서 사육한 건강한 ICR계 체중 20∼30gm의 mouse를 사용하였으며 정상대조군과 cycloheximide 투여군으로 구분하고 실험군은 다시 cycloheximide 투여 후 6시간군, 12시간군, 24시산군 및 36시간군으로 나누었고 각군에 10마리씩 배정하였다. Cycloheximide는 mouse의 체중 ㎏당 4㎎ 되게 생리적 식염수에 용해하여 0.1㎖를 복강내에 투여후 6시간, 12시간, 24시간 및 36시간 후에 희생시켜 간장을 적출하고 10% neutral formalin에 고정한 다음 cryostat로 두께 15㎛ 되게 동결절편을 만들어 Gomori법으로 acid phosphatase활성과 Wachstein 및 Meisel법으로 adenosine triphosphatase 활성을 관찰한 결과 다음과 같은 결과를 얻었다. 1. Cycloheximide 투여후 6시간, 12시간군 및 24시간군의 mouse 간소엽에서 중심 정맥부로 부터acid phosphatase 활성이 증가되기 시작하여 36시간군에서는 간소엽 전역에 중등도 이상의 강한 활성이 관찰되었다. 2. Cycloheximide 투여후 24시간군에서 부터 간소엽의 중심 정맥부에 ATPase 활성이 감소되기시작하여 36시간 경과군에서는 간소엽 전역에 음성반응을 나타내었다. 상기와 같은 결과는 cycloheximide 투여로 간장의 acid phosphatase는 간장이 손상을 입을 때 그 활성이 보다 강한 양성반응을 보이고 adenosine triphosphatase는 역으로 활성이 약해진다고 사료된다. It has been knwon that cycloheximide, an antifungal antibiotics extracted from streptomyces griseus, inhibits the growth of fungus. It has been reported by several investigators that this drug inhibits ribouncleic acid activity and protein synthesis of the mammalian cell. Recently, several reporters indicated that the cycloheximide causes the damage of hepatocyte. The observations by electron microscopic, histochemical and histological studies revealed that cycloheximide inhibits the RNA and protein synthesis by the injury of rough endoplasmic reticulum and the desocciation of polysome in hepatocyte. This study attempted, on the activities of acid phosphatase adenosine triphosphatase, phosphatelysis-enzymes distributed in the hepatocytes in the mouse liver. Healthy albino mice(ICR strain) of 20gm±in body weight were used as experimental animals which were divided into the control and cycloheximide treated groups. The animals of the cycloheximide treated groups were administered cycloheximide. (dissolved in physiological saline sol., by intraperitoneal injection in a dose of) 4mg per kg of body weight in a volume of 0.1ml, intraperitoneally. The experimental animals were sacrificed at intervals of 6, 12, 24 and 36 hours after administration of cycloheximide, respectively. The liver specimens were fixed with 10% neutral formalin, the sections of 15㎛ thickness were stained by Gomori, Wachstein and Meisel`s method for the detection of acid phosphatase and adenosine triphosphatase activities. The results were obtained as follows; 1. Acid phosphatase activity was increased in the central zone of liver lobule at the 6 hour and 24 hour period of the cycloheximide treated group, moderately positive activity was showed in the liver lobule at the 36 hour period group. 2. Adenosine triphosphatase activity was decressed in the centrol zone of liver lobule at the 24 hour period of the cycloheximide treated group. Negative reactions were showed in the whole liver lobules at the 36 hour period group. Consequently, it is supposed that cycloheximide caused increase of liver acid phosphatase result from liver damage, while adenosine phosphtase activity of the liver was decreased.

退溪 李滉의 養生法 小考

Toeye,s "Therapeutic Method without Medicine" can be regararded as fundamedal method of oriental medicine. It has three categories : natural therapy, spiritual therapy, and living therapy. First, natural therapy means the philosophy of man and natural as one unity by which human beings adjust themselves to nature, including nutritional diets. Second, spritural therapy implies one's own self realization and some techniques leading to today's "abdomen (commonly called Tan-Jeon) breathing." Third, living therapy is based on the principle that our own natural environment and food (commonly called Sin-To-Bul-Yi) are most suited to our body, practically concering all our lives in food, clothing and shelter. Therefore, Toegye Yi hwang's"Therapeutic Method without Medicine"(especilly his "17 Principles and 5 Secrets of Nutrition and Exercise Therapy") will serve as a good modern people to keep fit.
