As the integrated devices become more and more sophistcated, the diameter of wafers increased up to 300 mm and strict level of cleaning is necessary to remove the particulates on the surface of wafer. Therefore we need a new type of wet-station which can reduce DI water and chemical in the cleaning process. Moreover, it is important to control the temperature and the concentration of chemical in the wet-station. In the conventional chemical supply system, it is difficult not only to fit the mixing rate of chemicals in cleaning process, but also to fit the quantity and temperature. Thus, we propose a new chemicals supply system, which overcomes above problems by the analysis of fluid and thermal transfer on chemical supply system.

김종원,김정엽,최영복,Kim, Jong-Won,Kim, Jung-Youp,Choi, Young-Bok 한국정보처리학회 2003 정보처리학회논문지 C : 정보통신,정보보안 Vol.10 No.4

광 버스트 교환(OBS : Optical Burst Switching)은 광 지연선(FDL: Fiber Delay Line) 사용의 감소와 차세대 전광 네트워크에서의 광 스위칭 패러다임을 실현하기 위해 제안되고 있다. OBS는 버스트를 시분할 다중화함으로써 파장 라우팅보다 대역폭의 효율성을 제공하고 코어 네트워크에 대한 확장성을 제공한다. 최근, 광 버스트 교환망에서 어떻게 QoS(Quality of Service)를 제공할 것인가가 이슈가 되고 있다. 본 논문에서는 혼잡 발생시 우회 라우팅(deflection routing) 경로로 우선순위 0, 1, 2의 버스트를 우회시켜 QoS를 제공하는 우회 라우팅 방법에 대해 제안한다. 제안된 방법의 큰 장점은 QoS를 간단히 제공할 수 있다는 것이고, 이는 QoS 보장 알고리즘으로부터 제공된다. 또한, 제안한 QoS 제공방식은 각 코어 라우터에서 광 지연선의 사용을 최소로 하면서 트래픽을 공평하게 분배함으로써 효율적인 네트워크를 구현하게 한다. 제안 QoS 제공 방식의 우선순위 0, 1, 2 버스트의 QoS 보장과 효율적인 네트워크 사용에 대하여 OPNET을 사용한 컴퓨터 시뮬레이션을 이용하여 평가하였다. 이에 따른 결과로써, 높은 우선 순위 버스트의 종단간 지연은 향상되었으며, 또한 효율적인 네트워크 이용이 확인되었다. Optical burst switching (OBS) has been proposed to reduce the use of fiber delay lines (FDLs) and to realize the optical switching paradigm of the next-generation ail optical networks. The OBS can provide improvements over wavelength routing in terms of bandwidth efficiency and core network scalability via statistical multiplexing of bursts. Recently, another challenging issue is how to upport quality of service (QoS) in the optical burst switching networks. In this paper, we propose a deflection routing scheme to guarantee the QoS for the OBS networks to detour lower priority burst forward to the deflection routing path when congested. A big advantage of the proposed scheme is the simplicity of QoS provision, that comes from the simple QoS provisioning algorithm. Also, the QoS provisioning scheme be able to make efficient networks by fairly traffic distributing with the reduce of the use of FDLs at core routers. The QoS provisioning scheme has been verified to reliably guarantee the QoS of priority 0, 1, 2 burst and to efficiently utilize network resources by computer simulations using OPNET As results, the end-to-end delay of high priority burst is improved, and the network efficiency is also improved.

Considering six screen matrix to select an optimum remediation method for the Kunsan military base contaminated with petroleum oil, the following order was obtained: landfarming > biopile > soil washing > thermal desorption = incineration. When the landfarming method was applied for the remediation of 2,250 $m^3$ soil contaminated with petroleum oil ranging from 500 to 2,404 mg/kg as TPH, contamination level decreased below target concentration 450 mg/kg after 20~42 days depending on the initial contamination. From the evaluation of case studies of landfarming, it is suggested that ratty-truss or single-arch structure is suitable in the landfarming plant for the treatment of large-scale contaminated soil requiring long period of remediation. But, vinyl-house structure is suitable in the landfarming plant for the treatment of small-scale contaminated soil requiring short period of remediation. Therefore vinyl-house structure is recommended in the remediation of contaminated soil less than 5,000 $m^3$ requiring within 1 year of remediation period but ratty-truss or single-arch structure is recommended for the remediation of contaminated soil more than 5,000 $m^3$.

총 대퇴동맥 거대동맥류는 드문 질환이며, 수술 시기를 놓치면 하지 절단을 초래하거나 사망할수도 있기 때문에 적절한 시기에 반드시 수술적 치료를 하여야 한다. 환자는 72세 남자로 입원 20일 전부터 생긴, 좌측 서혜부 박동성 종괴를 주소로 입원하였다 전산화 단층 촬영과 디 지탈 감쇄조영술로 총 대퇴동맥 거대동맥류를 진단하고 응급수술을 시행하였다. 수술은 동맥류를 절제하고 표재성 및 심부 대퇴동맥을 PTFE (Gore-tex) 인조혈관을 이용하여 연결하였다. 동맥류 원인은 병리 조직검사상 동맥 경화성으로 밝혀졌다. Cardiac tamponade Is an acute, life-threatening emergency, requiring immediate decompression by a safe and simple method. The most effective method of drainage has been controversial. We experienced successful outcome for the treatment of cardiac tamponade with drainage using the Seldinger technique. The causes of the cardiac tamponade were hemopericardium after mitral and aortic valve replacement and malignant pericardial effusion due to primary lung cancer. They were treated with emergency rainage by the Seldinger technique without procedure-related complications. We believe that this technique is simple, safe for the treatment of cardiac tamponade.

The author made clinical study of 100 cases of empyema in infancy and childhood that were treated at the Department of Chest Surgery, Busan University Hospital and Busan Children's Charity Hospital, from Jan 1962 to Nov. 1975. 1. In infancy and childhood, 62 cases out of my 100 cases of empyema were caused by .staphylococci and most of recent reports showed a gradual increase in number of staphylococcal empyema. 2. Most frequent lesion predisposing to empyema in infancy and childhood was pneumonia (72%), being remarkable in staphylococcal empyema (85.5%) to that of others. 3. Antibiotics sensitivity test for staphylococci revealed that the erythromycin was most susceptible (85. 5%). 4. The mortality rate was 6% in over all and the author believes that from the point of view of surgical treatment, failure of early continuous drainage on account of multiple thoracentesis for the early stage of empyema, and also early open thoracotomy procedure such as decortication were all the contributing factors to higher mortality in the empyema of infancy and childhood. 5. It may be concluded that the treatment of choice for empyema in infancy and childhood were early and prolonged continuous drainage of pus by closed thoracotomy with caution and administration of more susceptible antibiotics with nutritional support.
