Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

신제품이 개발 출시되어 크게 성장 할 수 있다는 것은 그것을 채택, 수용해 줄 수 있는 혁신층과 조기수용자 층의 소비자 구조를 가지고 있어야만 한다. 신제품 수용자의 조기 확보는 신제품 개발에 소요된 비용은 조기에 보충할 수 있고, 많은 고객을 확보하여 매출의 증대가 용이하고, 마케팅비용의 감소를 가져올 수 있으며. 시장에서 리더십을 가짐으로써 효과적 시장 진입이 되기도 한다. 이와 같이 신제품의 수용과 확산의 연구에서 혁신성이 차지하는 중요도가 매우 높기 때문에 많은 관심을 끌어 온 것이 사실이다. 그러나 이러한 혁신과 수용성 연구의 중요성에 비추어 혁신성에 대한 발견 사실의 모호성과 함께 관련변수에 관한 끊임없는 논의가 지속되어 왔고, 동시에 혁신성 연구가 지금까지 취하여 왔던 방향과 주제에 관련해서도 많은 비판이 이루어져 온 것도 사실이다. 이러한 관점에서 본 연구에서는 아직 논리적으로나 실체적으로 방법론이 확립되어 있지 않은 디자인 혁신의 개념을 새롭게 정립하고 그 특징과 요소를 분석하고 객관적인 기준으로 변한 할 수 있는 지표를 찾는다. 또한 디자인 혁신에 있어서 유사성 판단에 관한 실험을 통해 제품 집단의 유형과 기준을 명확히 파악하고 각 샘플의 공간 해석과 함께 시자극적 특성을 정량적으로 평가하는 실험적 이론으로 사용하고자 한다. 이는 디자인에 있어서의 혁신을 인지하고 각 제품 속에 속한 샘플들을 특징별로 지각하는 보다 과학적인 디자인 접근방법에 관해 새로운 방향을 모색할 수 있도록 하였다. If a new product Is devised and to be sold, it Should possess the group of people who are inclined to change and accept the product, and the group of consumers who can buy them. If you occupy the consumers to buy the products earlier, you car make up with the expenditure that you have spent to devise and make products, facilitate the raise of the sales, decrease the marketing expenditure, and have effective access to the market by going ahead of others. Like this the Innovation has great influence in the accepting and spreading of the products. However in spite of these Innovation and acceptance, there have kept the ceaseless disputes about finding the Innovation and related function, at the same time the study of innovation has been criticized about the direction and the theme we have taken until now. From this point of view, the methodology has not been established In the area of logic and its reality, and this study tries to set up the concepts and analyze the characteristic and the elements and find the standard to change those characteristics and elements in to objective standard. In addition, through the judgment of the similarity In the design innovation, it tries to identify clearly the types and the standard of the set of the products, Interpret the space of each sample, and use it as the experimental theory to evaluate the visual characteristics, Thus it can perceive innovation of the design. perceive the characteristics of the samples in each products, and find the new direction in the more scientific access to design.

1. 금호강물에 대한 상대독성과 수온, 전기전도도의 경우 달서천 내부, 금호강과 달서천의 합류점 하부, 합류점 상부 순으로 값의 크기를 보였고 pH의 경우 역순을 보이므로 달서천이 금호강과 달서천 합류점 하부에 영향을 주는 것으로 사료된다. 2. 금호강 하천수에 대한 Microtox 독성값과 온도, pH, 전기전도도의 상관성은 없었으므로 기존의 일반적인 몇 가지 수질 인자로는 독성변화 및 수준을 판단할 수 없다고 사료된다. 3. 36시간 연속 모니터링을 통해 짧은 시간에도 독성값이 달라지는 것으로 보아 수질의 독성 수준이나 오염 수준을 판단하기 위해서는 연속적인 독성 조사 및 분석이 필요하다고 사료된다. 4. 하천수에 대한 연속 모니터링만으로는 하천 생태 위해도를 평가하기는 어렵다. 따라서, 하천 퇴적물에 대한 특성을 병행하여 조사 분석하는 것이 유해화학물질에 의한 하천 오염을 평가하는 방법이 된다고 사료된다. The main point source of pollution of the Keumho river in Taegu, Korea, stems from waste from the areas of industrial complexes. Although it is widely accepted that pollutants in waste water negatively effects general water quality, it is difficult to evaluate the effluent effect because of varying conditions in ambient water and inconclusive knowledge of causative pollutants. To analyze the water in relation to the industrial effluent in the area, pH, temperature, conductivity, and Microtox toxicity of various river samples were measured. Water samples were collected every 2 hours for 36 hours from Keumho river and Dalseo stream. Data from continuous monitoring for 36 hours showed that effluent in Keumho river originated from Dalseo stream, which is near adjacent to industrial complexes. Change in toxicity and other factors tested during the 36 hours indicated that continuous monitoring was necessary for a satisfactory effluent toxicity test. Furthermore, in addition to water quality monitoring, it was concluded that sediment toxicity also needed to evaluate effluent effects.

Despite the extensive literature on marine algae over the past few decades, a paucity of published research and studies exists on red algae. The purpose of this study was to evaluate the potential therapeutic properties of the ethanol extract of the red alga Callophyllis japonica against lipopolysaccharide (LPS)-stimulated macrophage inflammation. The C. japonica extract (CJE) significantly inhibited the nitric oxide (NO) production and the induced dose-dependent reduction of the protein and mRNA levels of inducible nitric oxide synthase and cyclooxygenase-2. Additionally, the CJE reduced the mRNA levels of inflammatory cytokines, including tumor necrosis factor-${\alpha}$, interleukin (IL)-$1{\beta}$, and IL-6. We investigated the mechanism by which the CJE inhibits NO by examining the level of mitogen-activated protein kinases (MAPKs) activation, which is an inflammation-induced signaling pathway in macrophages. The CJE significantly suppressed the LPS-induced phosphorylation of c-Jun N-terminal kinase, extracellular signal-regulated kinase and p38 MAPK. Taken together, the results of this study demonstrate that the CJE inhibits LPS-induced inflammation by blocking the MAPK pathway in macrophages.

VoIP 서비스는 인터넷을 기반으로 하므로 인터넷망에서 발생하는 보안 위험이 내재해 있고, 서비스가 실시간으로 이루어진다는 특성으로 인해 기존의 보안 솔루션으로 이러한 보안 위험을 해소하기는 어렵다. 따라서 VoIP 망 구축 초기단계부터 정보보호를 고려하여 보안대책을 세우고 이를 반영하는 것이 비용과 보안 효과 측면에서 바람직하다. 본 논문에서는 상용 VPN 제품에 공개 프로젝트인 SIP VoIP Gateway ‘Asterisk’을 연동하여 사용자 인증과 데이터 기밀성을 효과적으로 수행하기 위한 VoVPN(Voice over Virtual Private Network)을 설계하고 구현하였다.

The purpose of this study was to investigate the effect of balancing, coordinating and learning strategy on performance of private university hospitals. We think that the study will contribute to establish effective management strategy of private university hospitals. Data were collected from 69 private university hospitals. We measured balancing, coordinating and learning strategy, and perceived performance of the hospital by using 5-point Likert scale. Upper-grade general hospitals were significantly higher rate of growth and profitability than others. However, general hospitals were higher level in perceived performance than upper-grade general hospitals. Hospitals located in Seoul were significantly higher growth rate than those in other regions. Large-scale hospitals were significantly higher rate of growth and profitability than small hospitals. Qualitative performance did not different in any hospital characteristics. Growth of hospitals were significantly influenced from business strategies: selective strategy, formal coordinating strategy, and external learning strategy. Profitability of hospitals were also significantly influenced from business strategies: selective strategy, adaptive strategy, and external learning strategy. Subjective performance of hospitals were significantly influenced from external learning strategy. There were no factors that are significantly influencing on qualitative performance of hospital. To have successful performance in the competitive environment, it is recommended that private university hospitals should have to establish management strategy such as balancing, coordinating, and learning strategy.
