저자들은 비호지킨씨 림프종 환자에서 항암 치료 후 질환의 진행성 병변과 감별을 요했던 우폐 중엽의 단발성 종괴를 흉강경하 생검으로 폐 효모균증을 확진하고 amphotericin B와 fluconazole로 치료한 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Non-Hodgkin's lymphoma is monoclonal expansion of malignant B or T cells. The immunocompromised status in this disease is accompanied by many infections. The cryptococcosis, caused by Cryptococcus neoformans, frequently occurs in leukemia, Hodgkin's disease, sarcoidosis, diabetes mellitus, tuberculosis, and long-term steroid-using patients. Recent increasing incidence of fungal infection could be due to the spread of AIDS and transplantation. We experienced one patient with lung mass in Non-Hodgkin's lymphoma after three cycles of chemotherapy, which could not be discriminated from the newly developed lymphoma mass. Cryptococcus neoformans was isolated from the lung tissue obtained by thoracoscopic biopsy. Herein we report this case with brief review of pertinent literature.

Effect on the temperature, flow rate, and applied stack, voltage on zero-gap electrodialysis cell performance. Permeation of metal ion was increased with increasing temperature and flow rate. The temperature characteristics data were well coincided with Arrhenius type equation. As the applied stack voltage increased, the current density changing rate was increased rapidly with time due to the concentration polarization. It was proposed that not only the distance of electrode but also the flow pattern should be taken as a design factor electrodialysis cell.

Crushed Stone Pile(CSP) is suitable for improving soft silts and clays and loose silty sands. The effects of this method are increasing bearing capacity and slope stability, reducing settlement, increasing the time-rate of consolidation, and reducing liquefaction potential. In this study several model tests are carried out to investigate the bearing capacity of CSP treated ground. The results show that bearing capacity increases with the area replacement ratio and the preconsolidation pressure of the ground.

Background: Reactive oxygen species are produced under diabetic condition and possibly cause various forms of tissue damage in patients with diabetes mellitus. The aim of this study is to examine the effects of high glucose on the gene expression of superoxide dismutase(SOD) isozymes in rat insulinoma cells line. Methods: Rat insulinoma(RINm5F) cells were cultured with RPMI 1640 media containing high glucose(22.2mM), or normo-glucose(5.6mM) for 3 days and for 21 days. The SOD activities were determined by spectrophotometric assay and nitroblue tetrazolium (NBT) stain. The levels of SOD mRNA were quantified by reverse transcriptase-polymerase chain reaction (RT-PCR). Results: The CuZn-SOD activity was decreased but Mn- SOD activity was increased significantly in RINm5F cells which cultured with high glucose(22.2mM) media for 3 days. In RINm5F cells, the Mn-SOD mRNA content was also increased by high glucose, but the level of CuZn-SOD mRNA was not changed by gluose concentration for 3 days culture. Both CuZn-SOD and Mn- SOD activity were increased significantly when cultured with high glucose media (22.2mM) for 21 days. The levels of Mn-SOD and CuZn-SOD mRNA were increased in RINm5F cells cultured with in high glucose media for 21 days. Conclusion: These results suggest that in RINm5F cells, both CuZn-SOD and Mn-SOD gene expressions maybe increase by high glucose and decrement of CuZn-SOD activity, in cells of short term culture with high glucose contained media may due to the protein modification.

The purpose of this paper is to analyse evaluation characteristics according to a lighting method of exterior lighting. In this paper, we verified effectiveness of CG as an evaluation tool after we primarily extracted evaluation vocabulary via previous experiment. And then, we conducted subjective evaluation experiment after producing an evaluation object by CG according to a lighting method of exterior lighting. Finally, we analysed the factor of an evaluation result, analysing according to a lighting method of exterior lighting. The result of this paper is as follows: 1) The physical quantity presented by CG, compared with the real thing, is that the total relative error rate was within 5%. Also it did not have a quite difference in subjective evaluation experiment with the real thing in the most items excluding a part of evaluation items of subjective evaluation experiment by CG. 2) The 3 image axises of「exuberant」,「stable」and「warm」were selected as the result of the factor analysis In order to make sure the evaluation structure of exterior lighting. 「exuberant」and「stable」images were influenced a lot by a lighting method, and 「warm」image was affected by light color. The evaluation on the line lighting, the dot lighting and the compound lighting in「exuberant」image was high, and in「stable」image, the up and down lighting, the「transmitted lighting」, and the compound light were high. In「warm」image, the light color of yellow color as a warm color type was evaluated high, and the light color of green color as a cold color type was evaluated high in「mysterious」item.

CORBA를 기반으로 한 XML 정보검색 시스템 통합 구현

이재완,정병인 군산대학교 정보통신기술연구소 2000 情報通信技術硏究論文集 Vol.4 No.-

The Internet is convenient to use and makes possible to utilize the dispersed information source through single/unity interface so that it provides the most effective computing environment since 1990. But the current web reveals the limitation in data control and expansion due to the unstructured character of the HTML. The XML, the next generation language and developed to overcome the limitation of the current web, can make the data controlled and managed very efficiently. With these advantages the XML is now using broadly in the area of electronic commercial transaction, EDI, medical management system, etc. This paper shows that the development of 3-Tier client/server system with the CORBA basis dispersed object technique. It makes use of the advantages of XML and CORBA, which can make the document data access dynamically.

Color enhancement, contents of red pigment and capsaicin were studied with the dipping and field treatment of various levels of ethephon concentrations; 250, 500 and 1000ppms.The results were summarized as followings: 1. Dipping treatment effectively enhanced the coloring of the unmatured stages of fruit, especially, under younger fruit age. As the ethephon concentration increased, the remarkable effects were observed in Saegochu while Saemaul-Gumjang and Cheonan were less affected. 2. The optimum ethephon concentration for color enhancement were 500 and 250ppm in dipping and field treatments, respectively. 3. Red pigment content was slightly increased in 500ppm concentration level. 4. As the fruit age increased, capsaicin contents were increased in the ethephon concentration level from 500 to 1000ppm. In younger fruit slight increment was observed in the 1000ppm treatment.
