Seung-Jin Baek. 2004. Emily Dickinson's Homosexual Orientation. The British & American Language and Literature. 20-1. 115-128. In the Western feminist movement, the division between lesbian and heterosexual women played an important role in the development of the movement. The aim of lesbianism was to articulate connections between lesbianism and feminism and to create new and positive images. Lesbian feminists tried to challenge and supplant the oppressive stereotype which dominated public opinion. While the heterosexual feminist movement is formed in the established male-centered boundaries, lesbian feminists are primarily committed to women. That is, while heterosexual feminists try to achieve authenticity through the male-female relationship, lesbian feminists try to achieve authenticity through identifying themselves with women. Emily Dickinson participated in such relationships with women and practiced the concept of lesbian continuum throughout her life. In the poems dealing with the relationship with male sexuality, Dickinson is always hierarchically inferior to male sexuality which relegates women to sexual and family functions. The male power scorches and scathes her existence. So, Dickinson finds a way to identify and utilize specifically female power in her work and then tries to create a new consciousness which can be shared among women.

Background: Brief episode of coronary artery occlusion(i.e.,ischemic preconditioning) makes the heart more resistant to injury from a subsequent ischemic insult. Although a great deal of effort has been made in studying ischemic preconditioning, the underlying mechanism of ischemic preconditioning and its effect on hypothermic insult has not been elucidated. This study was performed to see whether ischemic preconditioning protects against the depression of cardiac contractility induced by hypothermic cardioplegic arrest/reperfusion. And recently, adenosine was known to have some correlation with the mechanism of preconditioning. If so, does this effect remain after the blockade of adenosine receptor by 8-phenyl theophyline? Method: Twenty-four Sprague-Dawley rat weighed 250-350g were used and divided into three groups. Rat hearts were removed rapidly, and each isolated heart paced with a rate of 180/min was perfused by modified Krebs-Hensleit buffer(KHB) solution on a Langendorff apparatus for an hour. After obtaining baseline data including left ventricular pressure(LVP), dp/dt, and coronary flow, cardiac arrest was induced by perfusion of 0℃ crystalloid cardioplegic(St Thomas) solution. After that, all hearts were stored in the same St Thomas solution at same temperature for 2 hours. In group Ⅰ(control group), the heart was reperfused by KHB solution. In group Ⅱ(preconditioning group), the heart was subjected to two 2-minute episode of global ischemia followed by 5 minute reperfusion with KHB solution(preconditioning) before cardiac arrest. In group Ⅲ(phenyl theophylline group), the heart was subjected to preconditioning procedure and 8-phenyl theophylline at 10μM in concentration was added to KHB solution at time of reperfusion. Observing parameter was obtained in each group at 10, 20, 40 and 60 minutes after starting reperfusion and compared statistically by use of one way ANOVA test(STASTICA, release 4.5). p-value less than 0.05 was considered significant. Results: Although depressed LVP, dp/dt, and coronary flow were seen in all groups during the reperfusion period, the preconditioned group showed more effective recovery of LVP than that of the control group, especially at 10, 20 and 40 minutes(p<.05). We failed to demonstrate the difference between the phenyl theophylline group and the control group(p=NS). Conclusion: These results suggest that ischemic preconditioning has protective effect on recovery state of hypothemic cardioplegic arrest/reperfusion. Its protective effect was limited during early reperfusion stage and was blocked by adenosine blocker.

요약문본 연구에서는 과거 7년간의 실측자료를 이용하여 대구지역 주요 대기오염물질에 대 한 대기오염도 분석 및 광화학스모그 기간중의 대기질 평가는 물론 대기오염도 해석에 지배 적인 영향을 미치는 기상자료를 이용하여 대구지역의 시정감쇄 요인분석 및 풍향, 풍속과 대기안정도를 분석하였다. 주요 대기오염물질의 일주 시간대별 농도변화는 아황산가스와 분 진의 경우 오전 8~10시경과 오후 4시경에 각각 최고, 최저농도를 나타내였고 이산화질소는 오전·오후의 교통량증가와 기상인자의 복합적인 영향으로 두차례의 최고농도를 나타냈다. 일산화탄소는 시간 환경기준치에 크게 못미치는 수준으로 동절기와 하절기의 시간별 농도변 화 양상이 서로 상이하게 나타났으며 오존은 일사량이 증가하기 시작하는 오전 10시경으로 나타났다. 또한 대구지역 오존농도의 발생빈도는 최근(1993~1994)으로 올수록 증가하는 경향 을 보였으며 오존농도와 그 영향인자와의 상관성 역시 일사량과 이산화질소가 가장 중요변 수임이 증명되었다. 최근 6년간의 기상자료를 분석한 결과 시정거리는 가을철이 월편균 17~20km 정도로 가장 좋았으며 풍향, 풍속 및 대기안정도는 서북서풍이 연중 14.0%, 2m/sec 이하의 저풍속이 전체의 36.5%, 중립조건인 D등급이 전체의 48.1%로 각각 나타나 대구지역이 대기오염의 확산에 불리한 조건임을 시사하고 있다.AbstractWith empirical data obtained for last 7 years, this study was conducted to analyze major pollutants and to evaluate the air quality of Taegu during the period of photochemical smog. In addition to this, causes of visibility reduction in Taegu, wind speed, wind direction and atmospheric stability were also analyzed. In terms of the variation of concentration for each pollutant by time during daytime, the highest concentration of SOz and partic ulates was measured at around 8~10 o'clock, and the lowest concentration of those pollutants was found at approximately 15~16 o'clock.In the case of NO;, due to the traffic and complex atmospheric conditions, the highest concentration was measured twice a day. The concentration of CO was much less than the atmospheric standard. The difference in the variation of CO concentration with respect to time was found between summer and winter. Ozone concentration increased with surging amount of insolation and the highest level of ozone was presented at between 15 and 16 o'clock with no respect to season. High concentration of ozone was observed much more requently in last 2 years (1993~1994) and it is verified that the insolation and NOz were main sources to be highly related to ozone concentration. As the result of investigation of meteorological data obtained for last 7 years, the highest visibility (17~20 km) was found in autumn as the monthly average value. As conclusion, the analyzed data-base indicated that it is difficult to spread air pollutants out of metropolitan Taegu city because of low wind speed (lower than 2 m/s), wind direction (Northwest), and atmospheric stability (D).

As modern people's interest in health grows, wearable healthcare-related technologies that can collect biometric information and receive health-related services regardless of time and place are developing. This paper proposes the healthcare system based on voice recognition function. Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.

P2P 모델에 기반한 혼합형 파일 검색 알고리즘의 설계

백승재,안진호 京機大學校 2006 論文集 Vol.50 No.-

Recently, peer-to-peer model is more preferable to client-server model in developing file sharing systems because of desirable features of the first such as scalability, anonymity, security, fault-tolerance and so on. However, the most well-known P2P file sharing systems Napster and Gnutella result in some scalability problems, centralized control and broadcasting in file searching, respectively. To address the problems, ultrapeers and dynamic routing techniques were proposed but, cannot still avoid incurring long response times and low recall rates of rare files. This paper presents a hybrid strategy to use existing Gnutella-like techniques for locating popular files and DHT-like techniques for searching rare ones. In particular, we propose an efficient DHT algorithm to structure a node ring consisting of only ultrapeers, not all the nodes. This feature makes the algorithm more scalable than the previous DHT ones in terms of the costs of file search, node join and leave operations and the number of routing table entries each node should maintain.

본 연구는 대구지방환경관리청과 유관기관 등에서 과거 7년간(1988~1994년) 측정한 대기질 관련자료중 아황산가스, 분진, 일산화탄소, 질소산화물 및 오존을 대상으로 통계분석하여 각기 배출강도가 다른 지역별 농도분포 특성을 평가하였고 대구지역의 전반적인 대기질 변화추이를 파악하였다. 그 결과 각 지점별 아황산가스의 농도는 전형적인 동고하저형을 나타내었으며, 도시가스공급과 황함량규제등 연료변환 정책의 효과로 인해 점차적으로 감소하고 있는 추세를 보이고 있다. 부유분진은 결측치가 많아 장기적인 농도변화추이를 판단하기는 어려웠으나 아황산가스와 같이 큰 계절적인 변동은 보이지 않았다. 질소산화물의 전반적인 농도분포는 장기 환경기준치 50ppb를 초과하지 않는 수준이었으나 최근엔 이동배출원의 영향이 가중되어 그 농도가 꾸준히 증가하는 추세인 반면 동고하저형의 계절적인 변동을 나타내는 일산화탄소는 가정용 무연탄 사용량의 감소로 대기중 일산화탄소의 농도는 점점 감소하고 있는 추세이다. 오존은 전반적으로 일사량이 많은 하절기에 농도가 높았고 동절기에는 농도가 낮은 경향을 보였다. 한편 주요 대기오염물질의 장·단기 기준달성도를 비교분석한 결과 대구지역의 대기오염물질중 아황산가스의 고농도 발생빈도는 공업지역에 집중되어 있었으며 질소산화물과 일산화탄소는 아직은 장·단기 환경기준을 초과하지 않는 수준으로 나타났고, 분진과 오존의 경우는 공업지역 뿐만 아니라 전지역에서 그 발생빈도가 유사하게 나타났다. In this study, characteristics and distributional patterns of the concentrations of air pollutants in Taegu area were evaluated using a data-base established from the ambient air quality monitoring stations for the period of 1989 to 1994. The result of this study demonstrated that in each sampling site, the SO_2 concentrations were much higher in winter than those in summer. However, a decreasing tendency was clearly shown in the annual variation of SO_2 concentrations, largely due to the use of LPG instead of anthracite coal for local heating systems and to the fuel policy of using lower sulfur content fuel in industrial sectors. Unlike SO_2, there was no distinct seasonal variation in the concentrations of suspended particulate matter. Concentrations of NO_x were found to be generally lower than the long term ambient air quality standard (50 ppb). The NO_x concentration has been gradually increased, reflecting the rapidly increased number of vehicles In this area, while the CO levels In ambient air were declind because of the reduced use of coal for domestic purposes. The Ozone concentrations in Taegu area exhibited that there has been already photochemical smog phenomena during the summer season when the insolation is strong.

A common form of relapse in adenocarcinoma of the stomach is intraperitioneal dissemination, in fact, among gastric adenocarcinoma patients who have undergone surgery intended to cure, approximately 50% of the patients develope initial recurrence in the peritoneal cavity regardless of the anatomic site of the primary tumor within the stomach. The efficacy of systemic postoperative chemotherapy to prevent peritoneal recurrence of gastrric adenocarcinoma is not satisfactory. There is still a great need for improved therapeutic strategies on the disseminated microscopic disease and small miliary nodules remaining on the peritoneal surface or lymphatics after operation. The authers have made fluorouracil-polyglycolic acid composite disks(Fu-PGA disks) with fluorouracil and biodegradable polymer: polyglycolic acid for more effective intraperitoneal chemotherapy. We inserted the Fu-PGA disk(s) in the peritoneal cavity of rat and pharmacokinetic study was performed to measure fluorouracil concentration in the peritoneal fluid, plasma, liver, kidney and heart tissue at 24 hour, 72 hour and 168 hour after insertion of Fu-PGA disk(s). Myelosuppressive action of this composite also was determined following its administration. The data of this study suggested that Fu-PGA composite will be a new device releasing drugs in a controlled manner and having targetability to peritoneum, and this device will be improving the efficacy of intraperitoneal chemotherapy for gastric adenocarcinoma.
