Bilateral chylothorax as a complication of radical neck dissection is extremely rare. Early diagnosis of chy-lothorax is important due to the consequences on metabolic & cardiopulmonary conditions. This present report describes our recent experiences with two cases of bilateral chylothorax following left modified radical neck dissection that was treated successfully by conservative management.

From April to October 2001, we studied on vegetation of 60 plots through the methods of Braun-Blanquet at Cheonsaengsan, Yuhaksan and Supdemisan in Gyeongbuk. Through the methods of interspecific affinity analysis, DECORANA and TWINSPAN the patterns of plant communities of 60 were analysed. It showed 6 communities at Cheonsaengsan, 5 communities at Yuhaksan, 6 communities at Supdemisan and total appearance of 128 species and covered with 50∼95% of tree layer, 20∼90% of shrub layer, 20∼90% of herb layer. As the result of interspecific affinity analysis it showed one big specific complex composed with 52 species and the 60 plots were divided into 4 groups by classification and ordination. One big species complex as a result of affinity analysis and eigenvalue of 0.303 at first step by classification indicate that Cheonsaengsan, Yuhaksan and Supdemisan are in developing stage of succession.

At the area of Yuhak, Cheonsaeng and Seongam mountains in Kyeongbuk, we studied the vegetation patterns with 75 plots on the base of Braun-Blanquet methods from March to October 2002. For the analysis of community patterns with 75 plots we used interspecies Affinity analysis method, DECORANA and TWINSPAN. The investigated area was divided into 17 communities with 177 species, and 20∼100% of treelayer, 10∼95% of shrublayer and 20∼100% of herblayer. By toe method of affinity analysis, it showed a big community with 86 species, but divided into 6 small groups by ordination and classification methods. Although it appeared as one group by the affinity test, the area divided into two groups by classification method at second level with eigenvalue of 0.320 and 0.430. It shows that the area of Yuhak, Cheonsaeng and Seongam mountains have own properties and in the process of succession.

The purpose of this study was to investigate to potective effects against transmissible gastroenteritis virus (TGEV) infection in piglets by administration of the TGEV antiserum orally at 5 hrs, 24 hrs and 36 hrs after birth. five piglets adiminstered the antiserum were experimentally infected with TGEV at four-day-old. Control group were four piglets infected with TGEV only. Serum antibody titers against TGEV were examined by serum neutralization (SN) test, dectection for TGEV or TGEV antigen from feces and small intestines was tested by reverse transcrption-polymerase chain reaction (RT-PCR) and indirect immunoflurescence (IFA). The results obtained were as follows; 1. The piglets administered the TGEV antiserum showed higher antibody titers than those of control group and sustained during the experimental period. 2. The detection rate of TGEV in feces and small intestines by RT-PCR were 24.5% and 20.0% in TGEV antiserum treated group and 44.0% and 75.0% in control group, respectively. 3. The detection rate of TGEV antigen in the small intestine by IFA were 26.7% in TGEV antiserum treated group and 75.0% in control group, respectively. It was concluded that oral administration of antiserum against TGEV to piglets was effective in preventing TGEV infection.

제 1보에서 Windows 환경 하에서 PSI/ISI 데이터의 효율적 관리 및 다원적평가와 분석이 가능한 고리 원전 PSI/ISI 데이터베이스 구축과 프로그램 개발(IDPIN)에 대해 소개하였다. 제 2보에서는 월성 원자력발전소 PSI/ISI 자료 관리를 위한 지능형 데이터베이스 프로그램(WS-IDPIN)을 개발하였다. 이 프로그램에는 월성 원전 PSI/ISI 관련 자료 분석 기능, PSI/ISI UT 검사 보고서 양식의 표준화와 전산 시스템화, PSI/ISI 비파괴검사 결과의 통계적 신뢰도 평가 프로그램(depth and length sizing performance 등) 등을 개발하여 원전 PSI/ISI 데이터 관리 전문가시스템(expert system)화에 한 단계 접근하였다. In a previous paper, we have discussed the intelligent Windows 95-based data management program(IDPIN) which was developed for (effective) and efficient management of large amounts of pre-/in-service inspection(PSI/ISI) data of Kori nuclear power plants. The IDPIN program enables the prompt extraction of previously conducted PSI/ISI conditions and results so that the time-consuming data management, painstaking data processing and analysis of the past are avoided. In this study, the intelligent Windows based data management program(WS-IDPIN) has been developed as an effective data management of PSI/ISI data for the Wolsong nuclear power plants. The WS-IDPIN program includes the modules of comprehensive management and analysis of PSI/ISI results, statistical reliability assessment program of PSI/ISI results(depth and length sizing performance etc), standardization of UT report form and computerization of UT results. In addition, the program can be further developed as a unique PSI/ISI data management expert system which can be part of the PSI/ISI total support system for Korean nuclear power plants.

Background: One nostril must be selected for nasotracheal intubation. In some cases, structural anomalies within the nasal cavity hinder the insertion of the tube or complications, such as epistaxis, develop. This study examined the possibility of using radiography to select the nostril that would induce fewer complications. Methods: Four hundred and five patients who underwent nasotracheal intubation under general anesthesia were studied. A 7.0-mm internal diameter nasal right angle endotracheal (RAE) tube and 6.5-mm internal diameter nasal RAE tube were inserted into men and women, respectively. Complications were considered to have developed in cases in which insertion of the tube into the nasal cavity failed or epistaxis occurred. The tube was inserted into the other nostril for insertion failures and hemostasis was performed in cases of epistaxis. The degree of nasal septal deviation was determined from posteroanterior skull radiographs or panoramic radiographs; the incidence of complications was compared depending on the direction of the septal deviation and the intubated nostril. Results: The radiographs of 390 patients were readable; 94 had nasal septum deviation. The incidence of complications for cases without nasal septum deviation was 16.9%, that for cases in which the tube was inserted into the nostril on the opposite side of the deviation was 18.5%, and that for cases in which the tube was inserted into the nostril with the deviation was 35.0%, showing a high incidence of complications when intubation is performed through the nostril with septum deviation (chi-square test, P < 0.05 ). Conclusions: Although there were no differences in the incidence rates of complications between intubation through the left nostril and that through the right nostril, radiological findings indicated that incidence of complications significantly increased when the tube was inserted into the nostril with the septum deviation.

This paper proposes a spatially distributed control scheme for a multi-layered cellular system to achieve flexible and high capacity wireless communication system under any traffic conditions including nonuniform traffic conditions. In the proposed system, terminals with lower mobility are connected to the wideband microcell systems to support variety of service including high bit rate data transmission and terminals with higher mobility are connected to the narrowband macrocell systems to reduce delay. To flexibly cope with temporal and spatial variations of traffic conditions, the ratio of the microcell and macrocell terminals as well as system bandwidth are adaptively and autonomously shared by both system Numerical simulation confirms that proposed scheme expressed flexible distributed location.

Rhabdomyolysis is a syndrome characterized by muscle necrosis and release of intracellular muscle constituents into the circulation. The spectrum of causes is quite broad and included disorders of traumatic, metabolic, infectious and toxic origin. However, rhabdomvolvsis and acute renal failure following bee sting is rare and its pathogenesis is not well known. We experienced a case of 63-year-old man with acute renal failure and rhabdomyolysis caused by bee sting. He was stung by bee on scalp and neck. Oliguria was developed within several hours. He has fully recovered after general supportive care including fluid therapy and diuretics. This case demonstrates that rhabdomvolysis with consequent acute renal failure are able to developed by bee sting.
