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.

Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

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.

As an actuator for direct drive(DD) manipulator. the travelling-wave type ultrasonic motor(USM) has many excellent performances and good advantages over conventional servo motors such as compact size, light weight, silent motion, low rotation-speed, high torque, low magnetic noise, high speed response, flexible free forms, large holding torque and so on. So it has been expected to be used as servo motor. This paper presents a design method of USM controller to adjust the phase difference of USM power using PLSI (Programmable Large Scale Intersration). we can control the elastic coefficient and the viscous coefficient of the USM by adjusting the phase difference of the motor power. By controlling the elasticity and viscosity, a robot can work in compliance with external environment. To use the result, we will be able to control the robot to reach its goal with compliance motion. It remains for further research to develop the impedance control of USM and to make cooperative robots.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

To evaluate the composition of Gae-Woo Jeot which is one of important traditional salted and fermented sea foods in Cheju Do, changes of nucleotides and their related compounds, free amino acids, TMAO(trimethylamine oxide), TMA(trimethylamine) contents and histological properties during fermentation was examined. AMP was as high as 3.6?mole/?? in raw small abalone but IMP content was only trace while hypoxanthine and IMP was dominant in raw topshell-4.5 mole/?? and 4.3??mole/?? respectively. Hypoxanthine was predominant in 65 days fermented Gae-Woo Jeot. Main amino acid in Gae-Woo Jeot were glycine, arginine, glutamic acid, alanine, valine and histidine in order. These were consisted 50~60% of the total free amino acid while phenylalanine, tyrosine, methionine and isoleucine were poor in content. During fermentation TMAO decreased slowly and eventually disappeard within 85 days while TMA was increased until 65 days and started to decrease down to 6~9mg%. Muscle texture showed the disappearance of elasticity soon after the adding of 10% salt while no change of texture was oberved until 50 days of fermentation in 20% salt group.

연구목적: 단순 초점주의 과제와 보다 고도의 집중을 요하는 작동기억 과제를 수행하는 동안의 뇌 활성화 양상을 비교하여, 두 인지기능 과정을 매개하는 정상적 신경회로의 특성과 차이를 알아보는 것을 목적으로 하였다. 방법: 정상인 14명을 대상으로 시각처리 대조 과제, 단순 초점주의 과제, 작동기억 과제 등 세 가지 인지과제를 주고, 과제 수행 동안 [□O]H₂O를 추적자로 한 양전자방출단층활영을 실시한 후 감산분석을 통해 초점주의와 작동기억의 신경회로 지도를 작성하여 비교분석하였다. 결과: 초점주의 동안 활성화되는 부위는 좌측으로 편측화되고 산발적으로 분포하는 양상이었고, 특히 전대상이랑과 운동영역을 포함한 전두엽, 일차 및 이차 시각피질 등의 활성화가 특징적이었다. 작동기억 동안의 뇌 활성화 역시 산발적 분포와 좌측 편측화 양상이 관찰되었으나, 시각피질보다는 전두엽의 활성화가 우세하였고, 특히 우측 전대상이랑의 현저한 활성화가 특징적이었다. 결론: 초점주의와 작동기억은 개념적으로 공통점과 차이점을 내포하고 있는 것처럼 매개 신경회로에서도 공통 혹은 특이한 영역을 각각 가지며, 전대상이랑의 역할이 두 기능에 공통적으로 중요하고, 이차 시각피질과 전전두피질이 두 기능 각각에 더 중요하게 작용하는 것 같다. Objectives:This study was undertaken to identify neural substrates for simple focused attention and more highly-focused working memory i normal people and investigate their characteristics and differences. Method: Fourteen normal subjects were studied with [□O]H₂O positron emission tomography during a visual processing baseline task, simple focused attention task and working memory task. Results were analyzed with the subtraction analysis to map the neural correlates of focused attention and working memory. Results: Activated areas during focused attention tended to be lateralized to the left and scattered over various regions including the anterior cingulate, motor area, and primary and secondary visual cortices. While the areas activated during working memory also show the left lateralization and scattered distribution, activation prevailed more in the frontal lobe than in the visual cortex, and was particularly remarkable in the right anterior cingulate. Conclusions: Focused attention and working memory do not have only conceptually commonalities and differences but also have common and specific areas in their neural substrates. The anterior cingulate may commonly play an important role in both cognitive functions, whereas secondary visual cortex and prefrontal cortex seem to be predominantly implicated in each function, respectively.

Selective posterior rhizotomy(SPR) has been known to reduce the spasticity as well as to improve the quality of life in patients with intractable spasticity. Twenty patients underwent SPR under intraoperative electrophysiological monitoring(IOM). Fifty-two percent of sacrolumbar rootlet were cut after electrical stimulation. Eighteen patients(90%) with spastic type of cerebral palsy showed marked reduction of spasticity and functional improvement without any complication. The patients who did not respond to SRP had mixed types of spasticity. IOM facilitate the selection of pathological rootlets regardless of anaesthetic level. intensity of electrical stimulation, and individual variability of responses. It is concluded that careful selection of surgical candidates and of pathological rootlets under IOM are important to reduce the spasticity. thereby to obtain a better outcome.
