Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive 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 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.

본 연구는 한국인의 삶의 질 향상을 위한 국민 생활체육 진흥정책 수립에 필요한 기초자료를 제공하기 위하여, 건강한 30-60대 서울시민(313명)의 체격과 근력, 전신지구력 등의 체력을 측정하여 문화, 경제생활수준이 서로 빠른 동경시민(509명) 및 북경시민(160명)과 비교 검토하는 것을 목적으로 하였다. 각국의 연구대상에 대한 측정은 사전에 협의한 동일한 방법(동경대학 체육과학실법)과 기기를 이용하였다. 체격요인으로는 신장과 체중을, 체력요인으로는 트레드밀 보행시 (90m/분)의 심박수와 보폭 그리고 자전거 에르고미터 운동시의 PWC75%HRmax와 脚筋伸展파워를 측정하였다. 신장 및 체중, 신체질량지수는 남녀 모두 북경, 서울, 동경시민순으로 높게 나타났다. 트레이드밀 보행시의 심박수는 남녀 모두 북경, 동경, 서울시민 순으로 낮은 값을 보였으며, 신장에 대한 보폭비율은 남자의 경우에는 북경, 서울, 동경의 순으로, 여자는 북경, 동경, 서울의 순으로 높았다. 脚筋伸展파워는 60대 여자를 제외한 남녀 모두 북경, 서울, 동경시민의 순으로 높았으며, PWC75%Hrmax는 남자 40대 와 여자 30대를 제외한 모든 연령 대에서 서울시민이 동경시민 보다 높은 경향을 나타냈다. 한편 모든 피검자를 대상으로 연령과 脚筋伸展파워와의 회귀식은 남녀 각각 Y=-0.30X+28.88(n=230, r=0.61, p<.001), Y=-0.l0X +12.49(n=611, r=0.32, p<.001), PWC75%HRmax와의 회귀식은 남녀 각각 Y=-0.01+ 2.50(n=116, r=0.29, p<.01), Y=-0.l0X+1.89(n=461, r=0.20, p<.001)이였다. 따라서 30~60대 서울시민의 체격 및 脚筋伸展파워는 북경시민 보다 낮게 나타나 삶의 질 향상을 위해 보다 적극적인 사회체육 활성화 방안 마련이 요망된다. The purpose of this study was to serve as a basis for making a health promotion policy for better quality of Korean life, by examining 313 citizens of Seoul's physical and leg extension power, physical working capacity who were in their thirties to sixties, enjoying good health, and by making a comparison of tile result with that of 509 citizens of Tokyo and 160 citizens of Peking who lived in different culture and living environment. The findings of this study were as below: First, the male citizens of Peking, who were in their forties to sixties, and the female citizens of the same city, who were in their fifties to sixties, were significantly higher in height, body weight and body mass index. Second, the male citizens of Peking, who were in their thirties and sixties, and the female citizens of the same city, who were in their thirties to forties, were significantly lower in heart rate in walking in the treadmill(90n/min). And there was a tendency that the citizens of Peking showed a higher ratio of stride to height. Third, the male citizens of Peking, who were in their fifties, and the female citizens of the same city, who were in their thirties to forties, had a significantly better leg extension power. As a result of examining all the subjects, there was a negative correlation between leg extension power and age. Fourth, all age groups of Seoul citizens, except males in their forties and females in their thirties, fended to be better in PWC75%HRmax than the citizens of Tokyo. When all the subjects were examined, there was a negative correlation between PWC75%HRmax and age. Consequently, there was a need to prepare more active plan to step up sports fur all successfully in order to improve the quality of life, as the citizens of Seoul who were their thirties to sixties appeared to be inferior in physical physique and leg extension power to the citizens of Peking.

In this paper, the speed control of induction motor was researched by presenting indirect vector control algorithm to improve the dynamic performance of induction motor, resulting in quick response characteristics such as DC motor. Speed detecting method was used by M/T method and made the simple speed calculation of the algorithm using the HSI.0 pin and HSI_TIME of 80C196KC. It was used each PI controller for current controller and speed controller of control algorithm, 80C196KC to CPU for fast velocity processing computation in designing the current harmonics of voltage sourace inverter. We would like to confirm through experiment the relatively fast response velocity with variable command-speed, applying proposed system to 5[HP] 3φ induction motor.

The authors report a rare case of gunshot injury to the head by a nail-gun which was treated by stereotactic surgery. The patient was arrived at our emergency room by 119 rescue. He was 23 years old with semicomatose mentality and decerebrated rigidity. On simple skull series and Brain CT scan, the large nail was located in the 3rd ventricular area in the mid-line with vertical stature. The entry point was identified 1 cm anterior to the coronal suture line and just lateral to the sagittal suture line. We planned stereotactic removal and the stereotactic frame was introduced to the patient. The foreign body was removed stereotactically with the guidance of C-arm fluoroscope. The # 8 L EVD drain was placed into the 3rd ventricle. Intensive care was performed to the young patient, but he died due to initial severe brain damage at # POD 6.

추정명사의 의미 결정을 이용한 복합명사 분해

김응균,서영훈 충북대학교 컴퓨터정보통신 연구소 2003 컴퓨터정보통신연구 Vol.11 No.2

본 논문에서는 분해패턴을 이용한 재사용 분해 알고리즘과 외래어, 이름명사, 지명인식에 의한 미등록어 추정을 이용한 복합명사 분해방법을 제안한다. 재사용 분해 알고리즘이란 현재 분해하는 음절보다 짧은 길이의 음절에서 사용된 분해방법을 재사용하여 분해가 이루어짐을 의미한다. 외래어 인식이란 한국어 음절에서 비교적 사용빈도가 낮은 음절들로 외래어가 구성이 됨을 이용한 인식방법을 의미하고, 이름 명사 인식이란 한국인의 이름특성에서 한자음을 차용하여 작명이 이루어지기 때문에 일정한 수의 음절이 반복적으로 사용되는 점을 이용한 인식방법을 의미한다. 지명인식 방법은 지명이 출현하는 패턴을 분석하여 지명사전의 검색으로 인식한다. 이와 같이 지명사전에 의한 지명인식과 알고리즘에 의한 외래어 및 이름명사 인식방법을 사용함으로써 미등록어 추정에 정확성을 기하고, 분해 정확률 향상에 기여한다. 실험 결과 미등록어가 포함된 약 1,500어절에 대해 약 98%의 정확률이 나타났고, 미등록어가 사전에 모두 등재된 후의 실험에서는 약 99%의 정확률을 보였다. In this paper, we describe a compound noun analysis using reuse algorithm and unknown noun presumption. A compound noun is analyzed based on predefined division patterns. Division patterns defined for shorter compound nouns are used when the length of a component in each pattern is the same as that of the shorter nouns. Characteristics of words of a foreign origin, human names, and location names are used for unknown nouns. Not only syllables used only in Korean words or in words of a foreign origin but also combining characteristics of Korean alphabets are used to analyze words of a foreign origin. Some characteristics of Korean human name are that it is generally composed of three syllables, a finite set of syllables are used as the second and the third syllable, and their combining is somewhat restrictive. We use those characteristics as well as characteristics of last name and some clue words following human names to analyze unknown word. Also proper nouns for location are used for compound noun analysis. Empirical result shows that system accuracy is about 98%, and about 99% when all unknown nouns are included in the system dictionary

양극반응 전류밀도를 변화시키면서 다공질 규소를 제작하여 라만산란을 관측하였다. 전류밀도가 증가함에 따라 라만신호는 520.5㎝-₁에서 멀어졌으며, 봉우리의 반치폭이 증가하였다. 또한 전류밀도 증가에 따라 원통형 다공질 결정의 직경은 감소함이 계산되었으며, 길이가 길어짐을 AFM으로 관찰하였다. The Raman scattering was studied from the porous silicons which were made by changing anodization current. As the current density was increased, it was observed that Raman was gradually far from the value of 520.5 cm￣¹and the full width half maximum increased. The decrease of radius of cylindrical porous crystal was calculated and the increase of its length was investigated through AFM.

Background: Neurotransmitter like substances in the gut have been proposed to contribute to the overall portal systemic encephalopathy (PSE). The source of the ammonia in patients with PSE is mainly the small bowel, as a result of the conversion of glutamine in the diet to glutamate and ammonia. PSE is highly responsive to changes in diet, to antibiotic therapy and to ingestion of nondigestible disaccharides such as lactulose. This study was performed to evaluate the relationship between PSE and oro-cecal transit time. In addition, performed to evaluate the effect of severity, cause, complications of liver cirrhosis on oro-cecal transit time. Methods: Between August 2006 and February 2007, 48 cirrhotic patients consecutively was enrolled in study their oro-cecal transit time after informed consent was obtained. A non-invasive hydrogen breath test was used to study oro-cecal transit time (OCTT). Result: The OCTT were delayed in cirrhotic patients with PSE compared without PSE (123.3 ± 42.7 min vs 170.0 ± 58.3 min, p<0.05). OCTT tended to prolongate further as the damage in the liver got worse, nevertheless the result was statistically meaningless (p<0.111). Neither presence of ascites or cause of PSE had any influence on gastrointestinal transit. Conclusions: Cirrhotic patients with PSE have more delayed OCTT than without PSE. Further research is needed to find out the relationship between OCTT and severity of liver cirrhosis.
