In a general centrifugal pump, if it is operated in a two-phase flow the activity of the impeller usually degrades and occasionally losses its function. However, the effect of break down of centrifugal pump due to entrained air has not been clarified yet. This paper shows the air-water two-phase flow characteristics of closed type and semi-open type impellers. In a sing1e-phase flow, closed-type impeller has higher efficiency and head. But in air-water two-phase flow semi-open type impeller's rates of decreases of efficiency and head are decreased.

Interest on when the North Korean regime will collapse is increasing due to the death of Kim Jong-il and the economic difficulties of North Korea. The system under Kim Jong-un looks stabilize disappearance, but the system can collapse at some point. On top of that, a majority forecasts that the Kim Jong-un system will fall apart in the long run. Hence Korean unification is the most important public age for Korean people. Kim`s death and the failure of Kim Jong-un`s succession can accelerate the unification regardless of our intentions; However, we are not ready for the unification. In this study, the preparation system for Korean unification was inspected, and what to prepare in concrete was suggested. In conclusion ,the preparation for the unification is not so ready that we need to hurry the preparation for the unification in order to take as politics, society and economy as well as to cure the wound from the division of Korean peninsula.

골내 결절종은 일반적으로 관절에 인접한 골단이나 연골하골에 위치하며, 낭종부위를 개방한 후 소파술 단독 또는 소파술 후 골이식술을 병용하여 치료한다. 저자들은 거골의 후방에 있는 골내 결절종의 치료로 후외측 및 후내측 삽입구를 통한 내시경적 낭종 내 소파술 및 골이식술을 시행하여 양호한 결과를 얻었기에 문헌 고찰과 함께 보고하는 바이다. An intraosseous ganglion typically exists in periarticular epiphysis or subchondral area, and is usually treated with open curettage of cyst or curettage and bone graft. We report a case of intraosseous ganglion of talus treated by endoscopic curettage and bone grafting with a review of the literature.

Objectives : BHT has been commonly used to treatment of brain disorders in Oriental clinic in Korea. The purpose of this study was to determine the inhibitory effect of modified BHT-C extract on the transient forcal cerebral ischemia in rats. Method : We prepared ischemic rats by the transient middle cerebral artery occlution(MCAO; 90 min occlusion and 144 h reperfusion) in rat brains. BHT-C extract (100 and 200 mg/kg, i.p.) was administered every day after the onset of MCAO until 6 day. Result : BHT-C extract increased survival rate of ischemic rats compared with vehicle-treated rats. BHT-C extract treated rats (100 and 200 mg/kg) were shown a significant reduction in infarct volume compared with vehicle-treated rats. Conclusions : These results suggest that BHT-C extract may contribute to its protective effects in brain ischemia through the reduction of brain infarction.

Extinguishing a fire at an early stage is most important to prevent spreading of a fire in Unmanned Engine Room. The most proper fire extinguish system was analyzed after examining the Automatic spread Extinguish System, which is mostly installed in Unmanned Engine Room, reproduced in the condition of real Unmanned Engine Room.

문화연구 위기의 이론적 기원과 알튀세르에 관한 기억

김성윤(Sung-Yoon Kim) 한국문화연구학회 2019 문화연구 Vol.7 No.2

이 글은 문화연구의 지적⋅정치적 위기와 알튀세르에 대한 이론적 억제가 가지는 상관성을 논구한다. 알튀세르를 통한 지적 혁신의 기회는 경험주의로 대변되는 영국의 지적 전통과 근본적으로 불화하는 것이기도 했다. 문화마르크스주의 전통에서 톰슨은 알튀세르를 이론적 환원주의자로 낙인찍었으며 윌리엄스는 정치적 주체의 기획을 알튀세르주의적인 계급 노선이 아 닌 그람시주의적인 대중 노선으로 변환시켰다. 그 결과 문화마르크스주의는 계급 형세에 대한 분석으로부터 멀어지게 됐고, 문화연구는 그 출발점에서부터 더 이상은 마르크스주의 내에서의 이론적 쇄신을 도모하는 것이 불가능하게 됐다. 홀은 과잉결정 개념을 비롯해 알튀세르주의에 대해 호의를 보이기는 했지만, 그에게 있어 알튀세르의 구조주의적 마르크스주의는 여전히 자율적인 정치 주체의 형성이라는 문제를 식별해내지 못하는 이론적 체계로 인식되었다. 그람시주의의 전격적 수용의 결과로 문화연구는 자본주의가 아닌 모더니티를 비평 대상으로 삼게 되었으며, 의도치 않은 결과였을 테지만 마르크스주의와의 접합을 상실한 채로 대중주의적 해석학으로 경도되기에 이르렀다. 오늘날 저항의 가능성을 원천적으로 내부화하는 후기-자본주 의의 문화논리는 문화연구의 이론적 쇄신을 요청하고 있으며, 이는 메타적 지배 형식에 대한 탁월한 통찰을 제공하는 알튀세르주의를 소환하는 맥락을 형성하고 있다. This article discusses the relationship between the intellectual/political crisis of cultural studies and the theoretical suppression of Althusser. The opportunity for intellectual innovation through Althusser was fundamentally at odds with the British intellectual tradition represented by empiricism. In the cultural Marxist tradition, E. P. Thompson stigmatized Althusser as a theoretical reductionist, and Raymond Williams transformed the planning of political subjects into Gramsian people’s line rather than Althusserian class lines. As a result, cultural Marxism has moved away from the analysis of class configuration, and cultural studies no longer allow for theoretical renewal within Marxist tradition. Hall favored Althusserism, including the concept of over-determination, but for him, Althusser’s structuralist Marxism was still perceived as a theoretical system that did not resolve the problem of the formation of autonomous political subjects. As a result of the acceptance of Gramsciism, cultural studies have turned to modernity, not capitalism. And cultural studies have gradually turned to popularist hermeneutics, losing their connection with Marxism. Today, postcapitalism’s cultural logic, which internalizes the possibility of resistance, calls for a theoretical renewal of cultural studies. This forms the context for Althusserianism, which provides an excellent insight into the form of meta-domination.

Year 2013 is the 63rd anniversary of breakout of the Korean War and the 60th anniversary of the establishment of Mutual Defense Treaty Between the Republic of Korea and the United States (on Oct. 3, 1953). In this study, I have investigated from the perspective of a policy process not so much who brought about the Korean War as through what policy decision-making led to the US intervention in the war. Policy agenda building process has two models. One is a human-oriented agenda building agent model that is concerned with who participates to use what agenda building strategy. And the other is the agenda building process model. In this study, I have focused on the human-oriented agent model to figure out what process created the policy for participating in the Korean War. Policy agenda building and leading group are divided into the externally driven type, the internally driven type, and the mobilized type. The externally driven type involves the agenda building process in which a group outside the government adopts government agenda while demanding that the government provide for what it requests. Contrary to the externally driven type, in the mobilized type, government policymakers lead the process of building government agenda. The mobilized type involves The internally driven type involves agenda built by bureaucrats who work with government agencies. Based on this theory, the policy decision-making that led President Truman to participate in the Korean War was the mobilized type. To be specific, not only the policy agenda on whether to send military forces, but also its details were dominated by the top national leadership including the president. From the perspective of a policy decision-making, I have brought light on the fact that the entire process was simply put on the fast track through the political decision by President Truman, from the adoption of the policy agenda of intervention in the war in Korea in the wake of the unanticipated breakout of the Korean War, the determination of the basic policy guidelines related to the character and size of the deployment, and the policy implementation in deploying the US troops to the Korean warfront.

Atrioventricular conduction disturbance is a rare clinical manifestation of Behcet disease. We describe a case in which a 48-year-old man complaining of dyspnea on exertion presented with complete atrioventricular block with junctional escape rhythm caused by Behcet disease. He also had moderate aortic regurgitation and mitral regurgitation. MRI and PET scan revealed inflammatory changes involving the ventricular septum and the ascending aorta. Recovery of atrioventricular conduction and improvement of valvular regurgitation were achieved with immunotherapy. Timely diagnosis and treatment of cardiac Behcet disease can prevent unnecessary pacemaker implantation. (Korean J Med 2014;86:65-69)
