Background : In recent years, gonorrhea has been panedemic and remains one of the most commom 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 VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Kim, Hyeong-Il,Shin, Sung-Woo Sustainable Building Research Center 2011 International journal of sustainable building tech Vol.2 No.4

The purpose of this paper is to introduce design considerations for the super tall building especially those related with sustainable design methodology and the topic presented in the SB11 Helsinki World Sustainable Building Conference by Hyeong-il Kim. The design of tall buildings should take into consideration of environmental impact and economic benefits from sustainable approaches to ensure low energy consumption and $CO_2$ emissions. In the paper, author tried to identify key issues related to sustainable building technology and emphasis the role of the sustainability in tall building design. The study also provides analytical survey of the significance of adaptable use of sustainable solutions that demonstrate use of renewable energy resources, and respond to climatic conditions with energy conscious design principles including form, orientation and materiality of the buildings on the current practice.

저자들은 우상복부 통증과 소화불량을 주소로 내원한 83세 여자 환자에서 국내 최초로 담낭 방선균증을 진단하고 치료 관찰 중으로 이에 문헌고찰과 함께 보고하는 바이다. Actinomycosis is a chronic suppurative and granulomatous disease, characterized by abscess formation, tissue fibrosis, and draining sinuses. Actinomycosis of the gallbladder is very rare and has not yet been reported in Korea. We report a case of actinomycosis of the gallbladder in an 80-year-old women with history of cholelithiasis for 3 years, preoperatively misidentified as gallbladder cancer. Histologic section of the gallbladder showed Gram-positive branching bacilli compatible with actinomyces. After cholecystectomy, the patient received intravenous ampicillin for 4 days, followed by amoxicillin for 4 months thereafter.

The Polyimide thin films based on PMDA and 4,4'-DDE were fabricated by VDPM, and their heat resistance characteristics were invastigated by TGA(Thermogaravimetry Analyzer). It was found that deposition rate decreased with increasing substrate temperature and the thin films were not fabricated over the substrate temperature of 70℃. T_TG of 5% weight loss temperature is 565℃, 397℃ and 210℃ at the substrate temperature of 20℃, 40℃ and 70℃, respectively. It is realized that the endurace temperature for 20,000 hour of thin films fabricated at 20℃ and 40℃ is 230℃ and 200℃, respectively.

Coicis Semen is one of the oriental medicine that has been used for the treatment of the disease such as pulmonary abscess, periappendicular abscess and wart since ancient times. However, the mechanism of the action of the drug is not well studied. This study was done to investigate the effects of Coicis Semen on the host defense mechanism. Effects of Coicis Semen on the immune responses were analyzed by measuring the contact gypersensitivity, hemagglutinin, hemolysin and rosette formation, cytotoxicity, and reactive oxygen intermidiates production. As the results, water extract of Coicis Semen administration enhanced the antibodies (hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen. Also Coicis Semen increased the allogeneic immune response in the mouse, showed cytotoxic activity against human leukemia cell line(K562) and decreased the contact hypersensitivity against dinitroflurobenzene. Also administration of Coicis Semen slightly increased NK cell activity and enhanced the production of such reactive oxygen intermidiates as superoxide and hydrogen peroxide from the macrophages in vivo and in vitro. The above results demonstrate that Coicis Semen has enhancing effects on cellular and humoral immune responses against disease.

강섬유보강 콘크리트의 파괴에너지 산정

金敬鎭,洪昌佑 충주대 산업과학기술연구소 2000 産業科學論文集 Vol.8 No.-

본 연구는 콘크리트의 파괴에너지를 결정하기 위한 편심압축실험의 가능성을 제시하였다. 실험변수로는 콘크리트 강도(200, 600kgf/cm2)와 강섬유 혼입량(0, 1.0, 1.5%)을 선정하였다. 재료적 파괴변수인 Gf와 cf를 갖는 콘크리트 파괴모델인 크기효과모델과 일반화된 크기효과모델을 사용하여, 동일한 크기와 다양한 노치를 갖는 방법을 사용하여 해석과정과 실험방법을 나타내었다. 이러한 변수는 콘크리트 구조물의 공칭강도를 결정하는데 필요하고 매우 중요한 특성을 갖는다. 또한 콘크리트 파괴역학을 적용하는데 있어서 Gf와 cf를 실험적으로 결정하는 것은 매우 중요하다. RILEM에 의해 제시된 크기효과모델은 다른 크기의 시편을 사용해야 한다. 그러나 이와같은 방법은 시편크기의 영향으로 인해 이 모델을 적용하는데 저해요인이 된다. 그러나, 본 논문에서 사용된 방법은 동일한 시편과 다른 노치로 인해 시험의 편리성과 단순성을 갖는다. This paper describes the possibility of the eccentric compression test for determining the fracture energy of steel fiber concrete. The test variables were concrete strength(200, 600kgf/cm2), steel fiber contents(0, 1.0, 1.5%). The SEL and its generalized theory present a fracture model of concrete in which material fracture parameters Gf and cf are objective. This paper proposes test and data analysis procedures for using this variable-notch one-size method. These parameters are not only necessary, but also sufficient for determining the nominal strength of any concrete structure. Therefore, experinental determination of Gf and cf is a key issue in application of fracture mechanics of concrete. The size effect method recommended by RILEM requires specimens of different sizes. This specimen requirement hinders application of the method. The proposed variable-notch one-size method allows use of specimens of the same size and the same shape. It provides more simplicity and convenience for test engineers and technicians.
