We tested whether ginsenosides $Rg_3$-standardized ginseng extract (RGE) has anti-stress effects in restraint-stressed animals. RGE increased time spent in the open arms and open arm entries in the elevated plus-maze test. In addition, RGE blocked the reduction of center zone distance and stereotypes behaviors in the open-field test. RGE also increased head dips in stressed mice, indicating anxiolytic-like effects. Stress decreased movement distance and duration, burrowing, and rearing frequency but increased face washing and grooming. RGE significantly reversed burrowing and rearing activity in stressed mice. In addition, we measured sleep architecture in restraint stressed rats using EEG recorder. Stress increased rapid eye movement (REM) sleep, but total sleep and non-rapid eye movement (NREM) sleep were not changed. RGE did not affect sleep architecture in stressed rats. These behavioral experiments suggest that RGE has anti-stress effects in restraint-stressed animal models.

The purpose of this study was to evaluate the clinical outcomes of patients with temporomandibular joint disorder before and after performance of arthrocentesis and stabilization splint therapy. The subjects of this study were 33 patients with limited mouth opening or pain or joint effusion who visited the Department of Oral and Maxillofacial Surgery, St Mary's Hospital, Catholic University of Korea. The arthrocentesis was performed and the stabilization splint was worn immediately after the arthrocentesis. Comparing the clinical outcomes of treatment at the times of first medical examination, 3 months and 6 months later on treatment. The results are as follows; 1. Statistically significant increase in the amount of maximum mouth opening occurred 3 months and 6 months later on treatment. 2. Statistically significant decrease in the average value of pain on test measured by VAS during maximum mouth opening, protrusive movement, right lateral movement, left lateral movement occured 3 months and 6 months later on treatment. The results suggested that arthrocentesis and stabilization splint therapy provide a improvement on patients with temporomandibular joint disorder when the exact diagnosis were provided.

Purpose: Superior orbital fissure syndrome is a rare neurological complex. Superior orbital fissure syndrome may result from a variety of inflammatory, infectious, neoplastic, iatrogenic, traumatic, vascular cause. The author report a patient who suffered from superior orbital fissure syndrome after inferior orbital wall reduction. Methods: A 26-year-old female suffered from inferior orbital wall fracture with inferior gaze limitation and orbital soft tissue herniation. On posttrauma 10 day, inferior orbital wall was reduced using endoscope and porous polyethylene ($Medpor^{(R)}$) was inserted. On immediate postoperation, she reported that extraocular movement was limited in almost any directions. She underwent exploration surgery to release the presence of extraocular muscle impingement. But, there was no observation of extraocular muscle impingement. On postoperative one day, high-dose steroid therapy was started to release superior orbital fissure syndrome which was defined in postoperative computed tomography. Results: After one month of high-dose steroid therapy, extraocular movement limitations improved progressively in all directions. In four months, extraocular movement recovered completely. Conclusion: Superior orbital fissure syndrome may occur after surgical procedure of orbital wall reduction. Prompt diagnosis and treatment with mega-dose corticosteroid is an effective option for avoiding disaster from compressive syndrome.

Nowadays, ethical consumers are increasing and they consider social values such as worker's human rights, environment and animal's welfare as key criteria in purchasing products. This study focused on the academic and practical research of ethical consumption, in which the needs and interests are now growing globally. This study addressed the concept, trend and practices of ethical consumption as well as seeking methods to support and promote ethical consumption. It examined the concept and types of ethical consumption from the perspective of the philosophy on ethical consumption. Ethical consumption was defined as a behavior that intended to improve the environment and the welfare of people and animals by purchasing products produced according to sound ethical principles and avoiding products that are made through the exploitation or the damage of people, animals and the environment. It also dealt with the practices of ethical consumption such as the fair trade movement, Clean Clothes Campaign, boycott, local food movement, animal's welfare movement. In conclusion, I suggested that consumers, companies, governments, and NGOs should make an effort to promote ethical consumption.

패킷교환식 다단계 상호 연결 망은 디지털 교환시스템과 슈퍼 컴퓨터분야에서 널리 이용되어 왔다. 본 논문에서 교환 요소내부의 여러 개의 패킷이 한 네트워크 주기동안 그 주기의 대역폭을 충분히 사용함으로써 다음 단계의 교환 요소로 전송되어 질 수 있음을 보인다. 기존의 상호 연결 망에서는 보통 하나의 패킷 전송을 가정했다. 다중 패킷 전송방식이 도입된 다단계 상호 연결 망의 분석적 모델이 소개되고, 컴퓨터 시뮬레이션에 의하여 그 모델의 타당성을 입증한다. 단일 패킷 전송방식을 이용한 전형적인 다단계 상호 연결 망과의 비교는 실용적인 크기의 연결 망에 대하여 처리율이 약 30% 정도까지 증가함을 보여준다. 비슷한 결과가 지연시간에 있어서도 얻어진다. 네트워크 전송량이 불균등한 분포를 나타내는 경우의 성능 향상은 더욱 중요하다.

The United States curriculum reform movement has recently started in each area of science education. The initiatives on curriculum reform stem from a notion that the low rate of science curricula offered in schools has been a serious problem. The schools in the United States are not only facing a lack of offerings within science curricula but also low enrollment in science courses, especially in physics, chemistry, and earth science. This trend resulted in low performances on international achievement tests including TIMSS and PISA. This paper introduces the efforts to solve existing problems through curriculum reform; including ChemCom, BioCom, EarthComm, and Active Physics. In this paper, a discussion is presented to show how the curricula can help address the status quo in science education. More specifically, this paper focuses on curriculum reform in high school earth science (EarthComm), providing a closer look at the scope and sequence of the reform movement. EarthComm was chosen because it was released based on the development of the National Science Education Standards (NRC, 1996). Consequently, EarthComm became a curriculum that espoused the visions of the Standards, which has been guiding the reform of the US curriculum. At the end of this paper, two research outcomes of the EarthComm curriculum implementation in schools are discussed in terms of student learning and differences from conventional curricula.

In the view point of the environmental conservation and the energy reduction, the recycling of metal scrap is coming as one of the global subjects in the world. In this study, the movement of intermetallics with electromagnetic force in a melt of a scrap of Al-Si-Cu alloy (JIS ADC12), which was widely used in diecasting process, was investigated in order to eliminate the Fe element, which was usually accumulated in a scrap. In this study, we applied electromagnetic method to eliminate Fe element in ADC12 aluminum alloy scrap which contains 1.64wt.% Fe and the effects of electromagnetic force on the particle movement was visualized and confirmed by water modeling and experiment. As a result, the Fe intermetallic compounds are moved to the direction opposite to that of the electromagnetic force as the force applies, thus eliminated from the bulk metal. Therefore, the content of Fe in matrix decreased from 1.64wt.% to 0.45wt.%.

Autonomia movement that emerged in Italy in the 1960s from workerist (operaismo) communism gives historical and discursive context to Manfredo Tafuri's famous criticism of ideology. His thesis on the death of architecture was a radical criticism of Keynesian intervention which was a strategy to cope with the Great Depression. For him, this capitalist development had taken away ideological prefiguration from architecture. At least Tafuri's this early intellectual phase was formed in the wake of magazine Contrapiano and Antonio Negri's influence. Tafuri almost entirely adapted Negri's thought on the importance of capitalist innovation that was uncovered by Keynes, Schumpeter, and Manheim and the periodization in modern history. When we read Tafuri's text with this concrete context, we can avoid being plunged into his abstruseness. On the other hand, 1980's Korea cannot understand Tafuri comprehensibly. 1980's situation to struggle to acquire democracy prescribed only one mode of reception of Tafuri's historiography in Korea. Tafuri's so-called pessimist view point could not satisfy student activists. They want to take intellectual means to sustain student movement and to secure political dynamics of protest. But at the same time they have anxiety to understand tafuri's thesis that they consider ad a critical theory for Korean Architecture. Double contexts of Tafuri's criticism of ideology bring to light to historicize both Tafuri's historiography itself and reception of his text in Korea.
