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.

This paper attempts to extract the crack tip stress intensity factors and to make a crack propagation model under mixed mode, from the finite element analysis of the concrete structures. In finite element analysis, all elements are initially assumed to be conventional quadratic isoparametric elements and are replaced by 6 node triangular singularity elements in the crack tip zone only. The stress intensity factors and the angle of propagation are carried out by displacement correlation technique and maximum circumferential tensile stress theory respectively. At the first part in a series of two papers, some numerical examples about the concrete SENB and DISK are presented to illustrate the practical effectiveness of the technique.

This paper proposes the rule-based expert system with auto-turning of PID controller gain and shows the efficiency of fuzzy expert system for the speed control of BLDC motor. The PID controller gain tuned using RZN(refined ZN) formula to initial tuning and fuzzy expert system to subsequent tuning. The fuzzy expert PID control method proposed in this paper results in the reduction of overshoot, the rapid response and the robustness for disturbances and noise.

북미자유무역협정(NAFTA)의 출범과 미국노사관계의 변화

임현진,최종철,홍성태 서울대학교 국제지역원 1996 국제지역연구 Vol.5 No.4

탈냉전 시기 미국의 새로운 국제전략은 세계 각국의 불균등한 발전상황을 적절히 이끌어 새로운 팍스 아메리카나의 시대를 열겠다는 명확한 목표를 가지고 있다. 기술 및 산업의 차원에서 이 목표는 정보통신분야의 주도권 장악으로 추진되고 있으며, 세계무역질서의 차원에서는 WTO와 NAFTA의 구축으로 젼개되고 있다. 여기서 NAFTA는 두가지 함을 갖는다. 첫째, 궁극적으로 지구적 지배력을 재구축하기 위한 지역적 발판을 마련하는 것이다. 둘째, 발전도상국과 선진국의 전면적 자유무역이 개신된다는 것이다. 미국 노사관계의 변화와 관련해서는 특히 두 번째 측면에 주목할 필요가 있을 것이다. 그러나 현재 진행되고 있는 미국 노사관계의 변화는 NAFTA 자체보다는 포드주의의 위기와 다른 선진자본주의국과의 경쟁에서 더 큰 영향을 받고 있는 것으로 판단된다. 즉 미국적 노사관계를 대표해 온 뉴딜형 노사관계와 실리적 조합주의의 한계에 대한 인식은 바로 이것들이 기반하고 있는 포드주의에 대한 비판과 대체의 과정에서 필연적으로 나타나고 있는 것이다. 이와 관련하여 NAFTA는 미국의 노동조합이 종래의 보호주의적 외투를 벗어버리고 개발도상국 노동자들과의 연대를 적극적으로 추구해야 할 필요성을 강화한다. 포스트 포드주의를 배경으로 미국의 자본과 정부가 주도하고 있는 실리적 조합주의에서 참여적 조합주의로의 변화에 대해 미국의 조동조합이 얼마나 적극적으로 대처할 수 있느냐의 문제는 새로운 국제적 연대에 얼마나 적극적으로 대처할 수 있느냐의 문제와 깊은 상관관계를 가질 것이다. The international strategies of America in the post cold-war period have the apparent objective that America will open a new pax-Americana age, by leading the unequal developmental situations among every countries in the world. This objective is propelled through holding the initiative in the field of information and communication in terms of technology and industry, and is developed by the establishment of the WTO and NAFTA in terms of the world trade order. Here, NAFTA has two implications; first, preparing for a regional platform so that America will be able to re-establish its global power; secon, the overall free-trade between advanced countries and developingcountries is beginning. With regardto the change of America's capital-labour relations, we need to call our attention to the second aspect. But it seems that the change of America's capital-labour relations in progress is more affected by the competition with other advanced countries than by NAFTA. That is, the recognition of the limits of the New-Deal capital-labour relations up to the present is necessarily emerging in the process of cirticizing and replacing Fordism which is regarded as a basis for both. Accordingly, NAFTA is strengthening its position on the necessity for labour in the US to actively pursue solidarity with unions in developing countries, taking off its old protectionist cloat. As for unions in America, how to cope with the transition from business unionism to participatory unionism which America's capital and government are leading in the back-ground of post-Fordism will be closely related with how actively to pursue a new international solidarity.

임태진,서규태,이택순,문병현 7개 국립대학교 환경연구 논문집 공동발행 위원회 2002 환경연구논문집 Vol.2 No.1

An experimental study was conducted to investigate the applicability of non-woven fabric filter as an alternative separation material in membrane combined activated sludge process. The most advantage of the fabric filtration activated sludge system is the low operation and maintenance cost resulting from the ready available material and gravity filteration. The system was consisted of two reactors, anoxic and aerobic one with working volume of 0.28㎥ and 0.47㎥, respectively. The non-woven fabric filter module was immersed in the aerobic compartment for separation of activated sludge by gravity filtration. Although the system showed high potential to treat domestic wastewater the initial leakage of bio-solid from the reactor and reduction of permeate flux were main problems of the system. The initial flux of 0.4㎥/㎡/day reduced to 0.2㎥/㎡/day in 12 days operation at 133㎝ water head. During the stable operation period, average SS concentration of effluent was 1.8㎎/L showing 96.4% removal. Organic removal efficiency was 98.3% as COD_Cr and 91.6% as BOD with the effluent concentration, 14.4㎎/L and 1.5㎎/L, respectively. T-N removal efficiency was 60% at C/N ratio 4.5.

팽이 재배에 있어 가장 큰 문제 중의 하나는 雜菌에 대한 汚染, 특히 細菌에 의한 피해가 극심하므로 作業段階와 栽培過程 전반에 걸쳐 培地徵生物相의 經時的인 密度變化에 따른 雜菌의 培地內 流入時期를 조사하여 汚染菌의 發生消長을 알아보기 위해 現地農家에서 시험해 본 결과 接種후 培養室에서 菌絲培養을 시작한 5일후부터 細菌이 檢出되기 시작하여 菌긁기전까지 약 25일간 0.5∼3.1×10⁴cfu/g의 密度를 보였으나 經時的인 密度增加는 없었고, 菌絲培養이 끝난 뒤 菌긁기직후부터 細菌의 密度는 118.3×10⁴cfu/g으로 급격히 높아졌으며 子實體生育 기간동안에 시간이 경과함에 따라 密度가 현저하게 증가되는 경향을 나타냈다. 이는 培養室 안으로 흐르는 空氣를 통하여 甁內로 細菌이 流入되고 또한 菌긁기 직후 培地表面에 灌注하는 물과 加濕機에서 噴霧되는 물粒子가 細菌의 密度增加에 절대적으로 영향을 미치는 것으로 판단되므로 이때가 細菌性褐斑病菌에 感染되기 가장 용이한 시기로 생각된다. 眞菌은 菌긁기후 子實體生育 기간동안 1.17∼7.87×10⁴/g의 密度로서 菌絲培養 기간동안의 密度보다 다소 높게 檢出되었으나 대체로 經時的인 密度增加는 보이지 않았으며, 放線菌은 거의 검출되지 않거나 菌絲培養 후 5일째부터 다소 검출되기 시작했으나 밀도가 매우 낮았고 經時的으로도 증가되지 않았다. One of the most serious problem on the Enoki mushroom cultivation is the infection by pathogenicitic microorganisns, especially bacterial diseases causing serious economical losses in the mushroom production. It was carried out to find the tendency of the development of mushroom diseases by temporal changes and variation of the densities of media microflora through the cultivation periods and working stages in a mushroom farm. According to the results, several bacteria were detected from the fifth day after the inoculation and incubation of mycelium in the incubation room, and the density of bacterium was 0.5∼3.1×10⁴cfu/g media for 25 days before the inoculum-removing, although there was no increment of the density. Since the inoculum-removing after the spawn run, the density of bacterium was rapidly increased as 118.3×10⁴cfu/g media, and was significantly increased by time during the growth period of fruitbodies. It was hypothesized that it is the most suitable period for the pathogen infection because the bacterium might be introduced by the air in the incubation-room, and the increment of bacterium density might be affected by moisture supplied through watering or humidifier in the growing room after the inoculum-removing. Fungi were detected as the density as 1.17∼7.87×10⁴/g media and the density was slightly higher than that during the incubation period of hyphae, although there was no significant increment. Generally, the density of Actinomycetes was disregardfully low, or Actinomycetes were hardly ever found, although there was found some 5 days after incubation hyphae in few cases.

Background and Objectives: Sniffin' Sticks test is the test of nasal chemosensory performance based on pen-like odor dispensing devices. KVSS(Korean Version of Sniffin' Sticks) Test was developed as the "Korean olfactory test" using the odorants which are familiar to Korean. Authors evaluated the clinical validity of KVSS Test compared with CC-SIT (Cross-Cultural Smell Identification Test) in Korean. Materials and Methods: The subjects of this study were 25 normosmic volunteers who were divided into five groups according to age. Each group was 5 normosmic volunteers. And they consisted of 12 men and 13 women. KVSS Test and CC-SIT were used for the evaluation of olfactory function. Results: Our study showed the negative correlation between age and olfactory function test (CC-SIT score, KVSS Test I score and KVSS Test II score). Normosmia rate of KVSS Test was more higher than that of CC-SIT. Also KVSS Test had more familiar items for Koreans compared with that of CC-SIT. CC-SIT score and KVSS Test score showed showed the positive corrclation. And each test revealed high reliability in test-retest evaluation. Conclusion: The KVSS Test can be used as an olfactory function test for Koreans.
