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.

Korean archery and chinese archery coincided with the origin of mankind. Bows were developed dramatically as shooting tools during the late Old Stone Age. Results of this study from comparison between Korean and Chinese archeries can be summarized as follows. Both of the archeries share their origin and their relevant ways of horse riding and stand-up. In Korean archery, ritual events are performed on a checker square to worship the heaven, the earth and the human being prior to arrow shooting. This is not found in Chinese archery. The two archeries are also different with each other in their materials. Finally, archery is a training for spiritual culture whose participants should do their best to discipline themselves and keep honest in daily life. In this selfish and mechanical society, archery should be established and developed as a popular and national sport through which people can make character training and enliven spirits facing the 21st century.

Accessory breast tissue is developed from persistence of breast tissue along the milk line which first beomes apparent at the 6th week of embryo and usually atrophies except for the thoracic area until the 9th week. It is much more common than amastia and occurs in approximately from 2 to 6 percent of the population. But multiple polymastia involving labia major is quite rare. We experienced one case of multiple polymastia involving labia majora & both axilla and 6 cases of polymastia & polyhelia, so we are willing to report our cases with a review of literature.

1. PKC activator인 PMA는 일차배양 HTSE세포로부터의 뮤신분비를 0.1μM 농도에서 30%, 1μM 농도에서 80% 가량 증가시켰다. 2. 식물 유래 성분으로, flavonoid의 일종인 TFR은 일치배양 HTSE 세포로부터의 뮤신분비를 10μM 농도에서 50%, 100μM 농도에서 80% 가량 증가시켰다. 3. 양이온성 폴리펩티드인 PLL 및 PLA는 일차 배양 HTSE 세포로부터의 뮤신분비를 0.01 - 10μM 농도에서 용량의존적으로 감소시켰다. 4. 결론적으로, 본 연구에서 얻어진 결과들은 새로운 거담제 및 점액용해제나 단백분해 효소제가 아닌 호흡기 류신의 생성/분비를 조절해 줄 수 있는 신개념의 약물을 개발함에 있어 극히 일부분이나마 단서를 제공하고 있다고 하루 수 있을 것이다. In the present study, we tried to investigate whether phorbol myristate acetate(PMA), trihydroxymethoxy-flavanone rutinoside(TFR) and cationic polypeptides significantly affect mucin release(secretion) from cultured hamster tracheal surface epithelial cells. Confluent primary hamster tracheal surface epithelial (HTSE) cells were metabolically radiolabeled with 3H-glucosamine for 24 hr and chased for 30 min in the presence of each agent to assess the effect on 3H-mucin release. The results were as follows : (1) Both PMA and TFR significantly increased mucin release from cultured HTSE cells ; (2) Cationic polypeptides including po1y-L-lysine(PLL, mw 7,500) and poly-L-arginine(PLA, mw 10,800) significantly inhibited mucin release from cultured HTSE cells, in a dose-dependent manner. This finding suggests us that PMA and TFR be further studied for the possible use as mild expectorants and cationic polypeptides might function as a regulator for hyper-secretion of mucus, both by direct acting on airway mucin-secreting cells, during the treatment of chronic airway diseases.

Disaster may be defined as a sudden calamitous event associated with great damage or destruction. A more common definition, among emergency-preparedness planners, is a medical occurrence that overwhelms medical care systems and facilities. Most regional disaster plans are formulated to respond to disasters of moderate size. At 07:50 A.M. on 28 April 1995, gas explosion was happened at Sangin-Dong where was going to be under construction of subway in Taegu, Korea. 102 victims had died and 178 victims had moderate or minor injuries. Problems in the organization at the scene, triage, field management, transport to the hospital, and the communication contributed to the confusion in the management of victims. An analysis of this disaster allows several lessons to be learn about perimeter control, command functions, crowd control, and transportation priorities. It will benefit disaster planners in other communities.

The raw water quality is being more polluted recently and other minute organic pollutants are inceasing. so that, good quality water supply is getting more difficult. This study shows organic pollutants removal efficiencies of 2 types pilot plants of Cl process and Bio process in Mongtan water tretment plant. Results in this study can be summarized as follows ; The NH_(3)-N removal efficiency of Cl process was very good, 97% but, that of Bio process was very poor, 10% The THM removal efficiency of GAC process was 95%, and The THMFP removal efficiency of BAC process was 80%. Thus, It is found activated carbon was very effective for the removal of the non-polar organic matter, such as Chloroethylene, Benzene, Toluene, THM et al. The highest THM produced by chlorition are 0.17㎎/ℓ in the winter. therefore, It is found that GAC process is necessary for treatment to THM

유전체 충전형 플라즈마 반응기를 이용하여 공기중 trichloroethylene (TCE)의 분해반응에 대한 연구를 수행하였다. 방전전력, 체류시간 및 반응물 유입농도 등과 같은 여러 가지 운전변수에 따른 TCE의분해효율을 조사하고, 반응 부산물의 분석을 통하여 TCE 분해 반응 메커니즘을 제시하였다. 실험결과 방전전력 및 체류시간이 증가함에 따라 TCE 분해효율은 증가하였으나 유입농도의 변화에 대한 영향은 거의 없었다. BaTiO_3를 충전한 반응기가 알루미나를 충전한 반응기보다 분해효율이 높았으나 TCE의 완전 산화분해의척도가 되는 CO_x(CO+CO_2)의 수율 및 CO_2의 선택도는 BaTiO_3를 충전한 반응기보다 알루미나를 충전한 반응기가 월등하게 높았다. 반응생성물 분석결과 주반응 생성물은 CO_x,CHCl_2COCl, C_2H_2Cl_2O_2및 COCl_2로 공기중 TCE의 분해 메커니즘은 주로 ClO와 OH 라디칼에 의한 반응으로 판단된다. The decompositon of trichloroethylene (TCE) in air using a ferroelectric packed-bed reactor was studied. The effects of discharge power, residence time, inlet concentration and other operating conditions on the decomposition efficiency were investigated and the analysis of reaction products was conducted to suggest the mechanism of TCE decomposition. Experimental results showed that the decomposition efficiency of TCE increased with increasing discharge power and residence time but was unaffected by inlet concentration. The decomposition efficiency for BaTiO_3 packed reactor was higher than that for alumina packed reactor, but the yield of CO_x(CO+CO_2) and selectivity of CO_2 as the measure of the complete oxidation of TCE were higher in alumina packed reactor. The main products of TCE decomposition were CO_x,CHCl_2COCl, C_2H_2Cl_2O_2 and COCl_2. On the basis of the results, it is inferred that the decomposition of TCE in air proceeds by OH and CIO radical reaction mechanism.
