Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

김제시 간척지역 천부 지하수내 철 환원작용 특성에 대한 고찰
김지훈,정태진,류종식,김락현,Kim, Ji-Hoon,Cheong, Tae-Jin,Ryu, Jong-Sik,Kim, Rak-Hyeon 대한자원환경지질학회 2013 자원환경지질 Vol.46 No.1
The study area is located on the western coastal region of Korea, partly had been reclaimed lands. Groundwaters of the coastal area show lower Eh and DO values (Eh: 0.57 V ${\rightarrow}$ 0.13 V, DO; 9.7 mg/l ${\rightarrow}$ 1.3 mg/l), and higher Fe concentrations (> 20 mg/l) than those of the inner land (< 0.3 mg/l), indicating that the redox condition of groundwater changes from oxic into suboxic/anoxic conditions as it flows from the inland toward the coastal area. In addition, Fe speciation of groundwater from the coastal area demonstrates that the most dissolved Fe exist as $Fe^{2+}$, reflecting that groundwater is under the anoxic condition to sufficiently occur Fe reduction. According to the result of Fe extraction with the sediment samples from three wells (A, B, C), the sediments provide enough $Fe^{3+}$ to occur the Fe reduction in the groundwater. Integrated all results of the groundwater and sediment, we infer that the Fe reduction to occur in groundwater is associated with the reclamation processes of the study area.

수용성 황색색소를 분비하는 Bacillus sp. PY123균주의 분리 및 특성
김광현,김지연 동의대학교 기초과학연구소 1998 基礎科學硏究論文集 Vol.8 No.1
To develop a yellow pigment for a food-additive, a strain producing a water-soluble yellow pigment was isolated from phylloplane of tree leaf. The strain PY123 was identified a Bacillus sp. based on morphological and biochemical characterization such as a bacillus form, mortility, spore formation, Gram positive, and catalase production. The pigment production of the strain PY123 was increased about 3 times in potato broth containing 1% sucrose and 0.1 mM CoCl₂than in only potato broth after incubation at 30℃ for 2 days. When 0.1 mM CoCl₂was added in potato broth containing 1% sucrose at late log phase during incubation of the strain PY123, cell growth was not inhibited, and the period at maximal pigment production of the strain PY123 was about 12 hrs faster than in potato broth containing 1% sucrose and 0.1 mM CoCl₂simultaniously.

Recent concerns about information privacy have enhanced the need for data security when storing information in a computer or transmitting it through data communication network. In this paper, we proposed the design DES(Data Encryption Standard) algorithm, which is regarded as a standard of encryption algorithm. We could design it by using of one-time ounging wit the implemental method, S-box sharing method, and the simple-round iterative method, and implement ASIC into simple-round iterative method have the smallest size and alternate to have a general purpose. Each part is designed in accordance with a type of the Top-down design using VHDL(Very high speed IC Hardware Description Language), this is designing technical language which is adopted as the international standard language, and. synthesized.

김문숙,이서희,오현남,한성지,김현주 서울여자대학교 자연과학연구소 1996 자연과학연구논문집 Vol.7 No.-
As the current stage of the fashion begins to follow the styles of the past, the study on the past costume is getting more important, and as the methodology of the study accurately approached study through the rehabilitation of the past costume is more needed than the simple rearrangement of the historical documents. By this methodology, this study can be positioned as a recreation activity. The results of the study are as follows. 1) Style : The general silhouetts is the late crinoline style which is the period from 1860s to just before bustle. The dress is one-piece composed of fitted bodice, and skirt which the front is flat, side and back is triangular shape to the skirts. 2) Color and Material : the main color is pale stone and the sub-color is ivory and blue. The dress is made of a silk surface and cotton back and partly satin and velvet. 3) Pattern and sewing : the dress is together sewing comnined with lining and fabric. The skirt is gored skirt, the number of patterns is plenty because of the plenty of width of skirt. The double piping has various effect not only to decorate but also to conceal the seam, support the silhouette. 4) Detail : The general detail is double piping which are repeatedly used to decorate stand collar, bands of sleeve, froint bodice and gored panel seam of skirt. And the fringe and velvet ribbon are used to decorate the dress. 5) Structural characteristics : The double piping, velvet ribbon and twilled cotton are used to emphasize structural characteristics of crinoline style. And the waistband which is backed with a webbing band to reinforce it is also the structural characteristics. Synthetically, the 1886~7 day dress has the characteristics of transitional stage in which the chararcteristics of the costume of 1860s and the remnants of the characteristics of the previous costume style, and shows the characteristics of day dress well in terms of the style, color and fabrics, pattern and sewing, detail, and structural characteristics.

한식 잔반처리를 위한 호기성 미생물의 분리 및 그 분해효과
김광현,김지연,이광배 동의대학교 기초과학연구소 2000 基礎科學硏究論文集 Vol.10 No.1
For the treatment of Korea food-wastes, three mesophilic and one thermophilic bacteria were isolated from soil and fermented fertilizers. The thermophilic Streptomyces sp. strain WF021 produced two enzymes which were a protease and a lipase at 55℃. The mesophilic Bacillus sp. strain WF024 produced four enzymes which were a protease, a lipase, a amylase and a cellulase when the strain was grown both at 30℃ and 55℃. The Bacillus sp. PY123 had produced three enzymes which were a protease, a cellulase and a lipase at 30℃. The Bacillus sp. strain CM1 produced three enzymes which were a protease, a amylase, and a cellulase at 30℃. The bacteria were grown in media containing 6% NaCl at least and did not have antagonism each other. The four isolates treated much more food-wastes than referance strains did. In a flask without aeration, three reference strains treated 15.4% of food-wastes, while four isolated treated 23.7% of food-wastes. In a flask with aeration, food-wastes were treated 67.3% by four isolates, and 64.3% by three reference strains, but 53.9% without bacteria. However, food-wastes were treated about 78% in a 200ℓ-reactor made by Siwon Co., while 65.8% in a 20ℓ-reactor made by Sanyo Co.
