The purpose of this paper is to study the process of change in ownership structure in the Russian oil industry and Putin's oil policy and its implication. For this purpose, author examined privatisation process of Russian oil industry. Russian oil industry has been completely restructured in the process of privatisation program of the 1990s. In result, vertically-integrated type oil companies was established during the terms of former President Yeltsin. After restructuring of russian oil industry, ownership structure was completely changed from state's control to private ownership. Since Yukos scandal happened, the dominant position of vertically-integrated oil companies declined and Putin government's control about oil production and export was more and more tightening. President Putin attempts to take back control of the oil industry. At present russian government use various policy as means of more controlled development of oil production and export. Taxation, licensing and oil pipeline system are considered as the most efficient tools. Based on the results of this study, author provides some implications about Putin's oil policy. Various statistics exactly showed efficiency of private oil companies in operating oil production and export. So author suggests Putin government take steps to guarantee profit of vertically integrated oil company and tax their excess oil rent at the rational level. Establishment of stable business environment suitable for activities of private oil company will be a win-win strategy for each other.

본 연구에서는 임목수확작업에 사용되는 집재기계의 작업효율성을 분석하여 경사가 급한(20° 이상) 작업조건에 적합한 가선계 집재기계를 선정하는데 기초 정보를 제공하고자, 타워야더(RME-300T), 트랙터부착형 집재기(일명: 춘천집재기), 트랙터윈치(FARMI) 등에 의한 집재작업에서의 작업생산성 및 비용을 비교 분석하였다. 평균 흉고직경이 20 cm, 집재거리 60 m, 가로집재거리 10 m, 그리고 기계이용률이 70%인 동일한 작업 조건에서 작업이 이루어질 경우, 타워야더의 1일 집재작업 생산성은 33.04 m3/일, 트랙터부착형 집재기는 38.47 m3/일, 그리고 트랙터윈치는 14.17 m3/일으로 분석되었으며, 이에 따른 집재작업비용은 각각 25,105원/m3, 20,520원/m3, 37,835원/m3으로 나타났다. 동일한 작업조건에서 집재거리에 따른 각 집재기계별 작업효율성을 비교하였을 경우, 집재거리가 40 m 이내로 짧을 경우에는 트랙터윈치에 의한 집재작업이 효율적이며, 40~140 m의 집재거리에서는 춘천집재기가, 140 m 이상의 장거리 집재작업에서는 타워야더가 가장 효율적인 것으로 나타났다. This study was conducted to provide field-based harvesting study information which can be used to select an optimal cable system for certain work conditions on steep grounds (>20° ground slope) in Korea. Toaccomplish this study objectives, we evaluated three cable yarding systems (RME-300T tower-yarder, Chuncheontower-yarder, FARMI tractor winch) working in typical work conditions for their yarding productivity and operational efficiency. Those yarders are commonly used for removing logs or trees on steep grounds in Korea. Under the same work conditions (average DBH of tree to be cut, 20 cm; yarding distance, 60 m; lateral yardingdistance, 10 m; and machine utilization rate, 70%), the average productivities were 33.04 m3/day, 38.47 m3/day, and 14.17 m3/day for RME-300T, Chuncheon tower-yarder, and FARMI, respectively. Our standardized cost comparison study also showed that the yarding cost was highest at 37,835 won/m3 with FARMI, followed byRME-300T at 25,105 won/m3 for the same work conditions. We found the lowest yarding cost with the Chuncheon tower-yarder at 20,520 won/m3 which was resulted primarily from high yarding productivity at theyarding distance (60 m). Our analysis suggested that a small machine such as FARMI could be a low-costyarding machine option for a cable yarding job with a short yarding distance (40 m or less). The Chuncheontower-yarder is well suited for a mid-range yarding distance job in Korea, ranged between 40 to 140 m. Ifyarding distance were longer than 140 m, the RME-300T tower yarder appears to be most cost-effective.

The objective of this study was to determine the effect of macrophages on growth of human colon cancer cells. The results showed that co-culture of colon cancer cells with macrophages inhibited the growth of colon cancer cells (HCT116 and SW620) depending on the number of macrophages, RAW 264.7 cells, and activated THP-1 cells accompanied by down regulation of pSTAT3 in cancer cells. We also found that expression and release of cancer cell growth inhibitory cytokines, IL-1 receptor antagonist (IL-1ra) and IL-10, was increased in macrophages. Blocking of the STAT3 pathway with specific inhibitor and siRNA of STAT3 abolished the growth of colon cancer cells and expression of IL-1ra and IL-10. In addition, neutralization of IL-1ra and IL-10 with antibodies resulted in reversal of macrophage-induced inhibition of cancer cell growth. These data showed that IL-1ra and IL-10 released from macrophages inhibit growth of colon cancer cells through inhibition of the STAT3 pathway

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Adsorption characteristics of activated carbon were affected by raw materials and operating conditions. Coal based activated carbons were prepared in a rotary kiln type furnace and the pretreatment effect of raw materials for preparing activated carbon was investigated. Steam was employed in manufacturing process as an activation agent. Activation temperature affected the properties of activated carbon. The adsorption capacity, or iodine value was increased in te activation temperature range of 800 to 900℃, yet decreased at higher temperatures than 900℃. Then, the activation effect was analyzed in terms of the activated carbon(AC) yield. It was found that the optimum heating rate and steam amount were 2.9℃/min, and 1g steam/g coalㆍhr, respectively. Effect of coal blends on the preparation of activated carbon was examined. The developing patterns of pore structure were varied with mixing ratio. As the amount of anthracite coal was increased, AC yield increased but adsorption capacity decreased. Pore size and pore size distribution were examined by BET specific surface area analyzer. In the AC yield range of 30∼40%, prepared activated carbon has micropores of sizes below 30Å and iodine value was above 1,000㎡/g in the temperature range of 850∼900℃. Benzene adsorption capacity was similar to those of mixed and Fushun coal but MEK adsorption capacity was superior to that of functions mixed coal. We found that the activated carbon based on coal has comparable to those of commericial products.

연구목적 : 알코올 의존 환자에서 세로토닌 합성 조절 효소인 tryptophan hydroxylase(TPH) 유전자 다형성 빈도를 정상 대조군과 비교함으로써 알코올 의존의 유전적 요인을 추적하고, 임상변인과 이 유전자 다형성과의 관련성을 알아보고자 하였다. 방 법 : DSM-IV진단기준에 부합되는 알코올 의존 환자 100명과 정상 대조군 100명을 대상으로 TPH유전자 다형성을 증합효소 연쇄반응과 제한효소 처리법을 이용하여 동정하였다. 여기서 분리된 대립 유전자와 유전자형에 따른 빈도의 차이를 서로 비교하였으며, 알코올 의존 환자군의 여러 임상 변인에 따른 차이를 비교하였다. 결 과 : 알코올 의존 환자군과 대조군 간에 TPH의 A216C 유전자형 및 대립유전자 빈도에서의 통계적으로 유의한 차이는 관찰되지 않았으나, 조기 발병한 환자의 경우는 유전자형의 빈도가 AA,AC,CC형이 0.57, 0.39, 0.04, 후기 발병한 환자의 경우 0.34, 0.45, -.21로, 조기 발병한 환자군에서 대조군과 비교하여 통계적으로 유의하게 A 대립 유전자의 빈도가 높은 것이 관찰되었다.(by chi-square test, p<0.05). 결 론 : 이는 조기 발병형 알코올 의존의 경우 TPH유전자 다형성과 관련이 있으며, 일부 알코올 의존 환자에서 유전적으로 세로토닌계의 이상이 있다는 사실을 시사한다. Objectives : This study was performed to explore the association of tryptophan hydroxylase (TPH) gene with diagnosis of alcohol dependence and/or clinical characteristics such as age of onset, family history, and severity of symptoms in Korean alcoholics. Methods : The genotype and allele frequencies of TPH in 100 male hospitalized patients who met DSM-IV criteria for alcohol dependence were investigated using polymerase chain reaction and restriction fragment length plymorphism and were compared with 100 age-matched healthy male control subjects. And the associations between gene polymorphisms and clinical characteristics in alcoholic patients were explored. Results : The distributions of TPH genotype and allele in alcohol dependent patients were not different from control subjects. However, the frequencies of TPH genotype in early-onset alcoholic patients, which were 0.57, 0.39, and 0.04(AA, AC and CC, respectively), were significantly different from those of late-onset alcoholics(0.34, 0.45, and 0.21, respectively). "A" allele was found more frequent in early-onset alcoholics. Conclusion : The result suggests that TPH gene polymorphism is associated with early-onset alcioholic patients possibly related with inherited abnormalities of serotonin system.
