1. Uzbekistan은 전통적인 농업국가로서 농업이 경제의 축이며 농촌인구가 60%,농업부문 종사자가 전 산업에서 차지하는 비율이 44%이고 농업생산이 GNP에서 차지하는 비중이 33%로서 비교적 높은 편이다. 2. 이 나라의 농업은 강우량이 적고 건조한 기후조건 때문에 주로 관개에 의존하고 있으며 안공수로와 저수지의 건설로 관개가능 면적은 430만㏊ 이고 충분한 수량만 확보된다면 700만㏊ 까지 경작이 가능하다. 농업생산은 목화, 밀, 벼, 포도, 채소, 멜론재배가 주종을 이루고 있으며 특히 일조시수가 3,000시간으로 매우 길고 일사량도 많아 목화, 고품질의 포도와 멜론 생산이 유명하다. 3. 축산업도 농업에서 중요한 부문으로 주로 유목에 의존하고 있으며 염소, 고기소, 젖소, 면양이 주된 가축이고 양잠업도 중요한 위치를 차지하고 있다. 4. Uzbekistan은 맥류, 목화, 포도, 사과, 양파 등의 원산지 일 뿐만 아니라 박과 작물의 2차원산지로서 유전적 다양성이 풍부하고 특히 멜론은 많은 재래종 품종들이 분화되어 재배되고 있다. 5. Uzbekistan는 1995년 한·우즈벡 농업기술협력 가능성 조사 이후 1996년부터 양국간 유전자원 공동연구가 활발히 추진되고 있다 금후 인근 중앙아시아 각국과의 유전자원 또는 농업관련 공동연구를 수행함에 있어 우즈베키스탄을 전진기지로 활용하는 방안이 적극 모색되어야 할 것으로 사료된다. The Republic of Uzbekistan is located in the central part of the middle Asia. The area of the Republic makes up 447.4 thousands ㎢ and about 60% of the country is semi-desert or desert with only 4.5 million hectares of the area cropped. The average temperature in July on the plains' territory varies from 26℃ in the North to 30℃ in the South, and the average temperature in January falls to as low as 0℃ in the South and to -8℃ in the North. Precipitation primarily occurs during the winter-spring period. Annual precipitation amounts to 80-200 ㎜ on the plains, 300-400 ㎜ in the foothills area and 600-800 ㎜ on the eastern and south-eastern slopes of the mountain ridges. Natural pastures occupy 50.1% of the total area of Uzbekistan, and 9.7%(4.3 Min. ha) of irrigated lands. Irrigated land is mainly cultivated for cotton, spiked cereals, rice and potato. Cotton plants occupy 36.5% of the cultivated areas and grain crops 39.5%. Given the abundance of solar radiation and heat, the major factor limiting the use of agroclimatic and land resources is a deficit of water. Agriculture in Uzbekistan was and still is the largest sector in Uzbekistan's economy. Agriculture and it's related industries account for approximately 33% of GDP, and 55% of the hard currency revenues of the country is related to Agriculture. Approximately 60% of the population resides in rural areas, and 44% of the work force is engaged in agricultural production. Uzbekistan is the world's fifth largest cotton producer and the second largest exporter. Cotton has been center to the economy because it accounts for about 50% of the country's export earnings. At the same time, however, cotton production has depended on vast amounts of irrigation, and this has had a possibly significant irreversible negative impact on the Aral Sea. The development strategy in the agricultural sector in the country is targeted at ensuring food and environmental security, while increasing the efficiency and export-potential of domestic production. According to the macroeconomic forecast, the agrarian sector will maintain its leading role in the economy (at 25% of GDP). To meet the strategic development goals by 2010, annual growth in agricultural output must be at least 5-6%.

The effects of physostigmine and procyclidine, as a combinational prophylactic regimen for organophosphate poisoning, on learning and memory process were examined in rats administering subcutaneously. Procyclidine at doses of 3 through 10 ㎎/㎏ produced significant impairment of learning and memory process in step-through passive avoidance test. However, this harmful effect of procyclidine (3 and 5 ㎎/㎏) was reversed by simultaneous injection of physostigmine (0.1 ㎎/㎏). Procyclidine at doses of 7 and 10 ㎎/㎏ produced reversible inhibition of learning and memory process in Morris water maze test. Physostigmine (0.1 ㎎/㎏) recovered the memorial impairment induced by procyclidine in this test. In conclusion, procyclidine can affect learning and memory process at the doses not less than 3 ㎎/㎏, and the dose of procyclidine to influence the learning and memory process in rats might be increased to more than 5 ㎎/㎏ by the simultaneous administration of physostigmine (0.1 ㎎/㎏).

Herpes Simplex Virus Type 2 Seroprevalence in Korea: Rapid Increase of HSV-2 Seroprevalence in the 30s in the Southern Part

Haeng Seop Shin,Jeong Joo Park,Chaeshin Chu,송현제,Kyung Soon Cho,Joo Shil Lee,Sung Soon Kim,Mee Kyung Kee 대한의학회 2007 Journal of Korean medical science Vol.22 No.6

To determine the characteristics of seroprevalence of herpes simplex virus type 2 (HSV-2) infection among Korean people, a cross-sectional study was conducted on three groups in 2004. The three groups consisted of the general public who visited public health centers, commercial sex workers (CSWs), and human immunodeficiency virus (HIV)-infected persons. Among the general public, HSV-2 seroprevalence rates for age under the 20s, in the 20s, 30s, 40s and the above 22.6%, 32.7% and 32.3%, respectively, which showed rapid increase of the rate in the 30s (p<0.0001). In case of the above of 19 yr old, women (28.0%) was higher than men (21.7%) (p<0.0001). The rate of CSWs (81.6%) was about 10 times higher than that of general women. In case of HIV-infected men (47.6%), the figure was about 2-3 times higher than that of general men. The low rate in the teens and the 20s proved that it is essential to develop sexually transmitted infections (STIs) prevention programs of education and publicity for them as a precaution measure. This study is the first major study of its kind on HSV-2 and would provide basic data for prevention of STIs including information about target groups subject to vaccination program.

Expression Patterns of Diverse Genes in Response to Gamma Irradiation in Nicotiana tabacum

Cho, Hye Sun,Lee, Haeng Soon,Pai, Hyun Sook 한국식물학회 2000 Journal of Plant Biology Vol.43 No.2

We investigated the expression patterns of diverse genes at various time points after gamma irradiation of young tobacco plants. The first group of genes showed stimulation of transcript levels upon gamma irradiation, although their induction patterns varied. This group included glutathione-S-transferase, peroxidase, superoxide dismutase, and catalase. A second group, with post-irradiation reduction of transcripts, included genes encoding cytosolic ascorbate peroxidase, stromal ascorbate peroxidase, and a TMK1 receptor-like kinase. The third group of genes either showed no change in transcript levels or exhibited irregular patterns. These included genes encoding PR1a (pathogenesis-related protein), tobacco Ca^++-dependent protein kinase, the β-subunit of translational initiation factor 2B, and CHRK1, a chitinase-related receptor-like kinase. Thus, various genes displayed differential patterns of gene expression in response to gamma irradiation in tobacco plants, thereby suggesting a complex signaling mechanism is involved in the irradiation-induced defense by plants. In addition, many stress-responsive genes exhibited gene expression patterns upon gamma irradiation that differed from those resulting from other biotic and abiotic stresses. With the knowledge of distinctive expression patterns of diverse genes, irradiation-indicating marker plants could be developed by engineering and monitoring multiple radiation-responsive genes.

Urinary Dipeptidase in Pregnancy

Cho, Sun Hee,Park, Haeng Soon 전남대학교 약품개발연구소 1996 약품개발연구지 Vol.4 No.1

The specific activity(S.A.) of dipeptidase in placental homogenate was less than that of renal dipeptidase(RDPase; E.C. 3.4.13.11) of kidney homogenate with two orders of magnitude. The urinary dipeptidase(Udpase) in urine samples of pregnant woman were compared with the urine of controls, nonpregnant individuals. Udpase in raw urine were assayed fluorometrically by three-enzyme coupled assay. Previously it was reported that S.A. I(unit/g protein) may be used as an index of renal damage but S.A. II(unit/g urine creatinine) were not adequate. The values of S.A. I of the pregnancy were significantly lower than the controls which were not distinguishable from patients with acute renal failure. The values of S.A. II of the pregnant individual were in the same range or somewhat higher than the controls. The results indicate that neither S.A. I nor S.A. II are adequate to be used as indices of renal disease during pregnancy.

A successful treatment of infants and children with congenital heart defects depends upon several factors: diagnosis must be accurate, the operative technique, including techniques of perfusion and myocardial preservation, must be suited to the needs of patients and intensive cares, including accurate anesthesia, must be applied through all stages of investigation and treatment, i.e. before, during and after the operation. Recently we performed a open heart surgery successfully for a six-years old girl who had suffered from frequent upper respiratory tract infection and mild to moderate exertional dyspnea with congenital heart defects (ventricular septal defect, Kirklin type II, with patent foramen ovale). The operation and postoperative course were very smooth. And now we report this with review of literatures.

The Inhibitory Effect of Dimethylsulfoxide on the Synthesis of Muscle Specific Protein during Chick Embryonic Myoblast Differentiation

Cho, Eng Haeng,Ha, Doo Bong,Choe, Rim Soon 연세대학교 자연과학연구소 1988 學術論文集 Vol.21 No.-

계배 근세포를 분리하여 배양하면서 근세포 분화기간 동안 몇 가지 근특이 단백질들의 합성에 대한 dimethyl sulfoxide (DMSO)의 억제 양상을 검토하였다. 전기영동겔상의 각 단백질 성분들을 densitometer로 scanning한 결과 DMSO를 처리한 구와 무처리구간에 비슷한 분포를 보였으나 근특이단백질인 actin과 myosin의 상대적 양은 현저한 차이를 보였는데 이것은 근세포 분화기간 동안 총단백질의 합성이 DMSO를 처리한 세포에서 감소한 때문이라고 보여지며 그 결과 근세포 융합이 억제된 것이라고 생각된다. 그외에 아세틸콜린 수용체와 creatine phosphokinase도 또한 DMSO에 의하여 그 합성이 억제된 것을 볼 수 있었으며 배양액에서 DMSO를 제거 하였을 때 근세포 융합이나 총단백질 합성량 및 아세틸콜린 수용체의 합성은 다시 증가하였고 무처리 상태 가까이 회복되었다. The pattern of inhibition by DMSO on several muscle specific proteins synthesis during myogenesis was studied. The profiles of protein in densitometric scans on SDS-polyacrylamide electrophoresis gel showed similar pattern in DMSO treatment and untreatment. But the amount of actin and myosin in the densitometric peak was revealed significant difference. Therefore, it seemed to be that total protein synthesis during muscle cell differentiation was decreased in DMSO-arrested cells, and this resulted in inhibition of cell fusion phenotypically. The synthesis of other proteins, acetylcholicne receptor and creatine phosphokinase, was also decreased by DMSO. The inhibition of total protein and acetylcholine receptor by DMSO was reversed and cell fusion was restored nearly to control in 2-days after DMSO removal.

수소 정제를 위한 다탑 PSA 공정의 해석

조순행,서성섭,김종남,신흥수,장동근 한국화학공학회 1999 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.37 No.6

석유화학공장에서 나오는 배가스인 수소, 이산화탄소, 일산화탄소, 메탄의 원료혼합가스로부터 수소를 회수할 수 있는 다탑 PSA공정을 orthogonal collocation법에 의해 전산모사하였다. 고순도 수소를 생산하기 위하여 흡착성능이 다른 두 흡착제를 연속으로 충전시킨 4탑 9단계 공정을 대상으로 하였다. 제올라이트와 활성탄의 충전비율은 제품의 순도 및 회수율에 영향을 미치며 각 흡착제에 대한 최적의 충전길이는 각각 60 ㎝이었다. 주어진 충전비율에 대해서 최적의 흡착 압력과 원료기체 공급 속도가 각각 19 atm 및 11.0 ㎝/s로 결정될 수 있었다. 고압에서 저압으로 떨어지면서 세정기체를 공급하는 항류 감압단계에서 압력 변화의 크기(DP) 즉, 세정 단계로 공급되는 세정기체의 양이 제품의 회수율과 순도에 크게 영향을 미쳤다. DP가 1.3 atm이상에서는 DP가 증가함에 따라 순도가 크게 변하지 않았지만 회수율은 계속 감소하였다. DP가 커질수록 압력균등화 병류감압단계에서의 압력이 낮아지고 세정단계 다음에 이어지는 압력균등화 항류가압단계에서의 균등 압력도 낮아졌으며, 이에 따라 생성물 가압단계에서 압력을 높이는데 필요한 기체 생성물의 양이 증가하였다. Numerical simulation for hydrogen-recovery multibed PSA process was performed by orthogonal collocation method for the feed mixture gas of hydrogen, carbon dioxide, carbon monoxide, and methane in petrochemical plant. A fourbed and nine-step process using a layered-bed which was consecutively packed with two different adsorbents in one bed was employed to produce high-purity hydrogen. The packing ratio of zeolite to activated carbon affected the purity and recovery of the product. The optimum length of zeolite layer and that of activated carbon layer were 60 ㎝ each. The optimum adsorption pressure and feed velocity could be determined to be 19 atm and 11.0 ㎝/s, respectively, for the given packing ratio. The recovery and purity of the product were strongly affected by Difference-Pressure(DP) which was defined as the difference between the initial high pressure and the final low pressure at the cocurrent blowdown step which delivers purge gas to the low pressure bed. When the DP was larger than 1.3atm, the purity did not change much and the recovery was continuously decreased with increasing DP. As DP increased, the pressure at the pressure-equalization cocurrent depressurization step was lowered and the pressure at the pressure-equalization countercurrent pressurization step following purge step was also lowered. Therefore, the amount of the high-pressure product to pressurize the low-pressure column increased.
