        This study was conducted to examine the condition of patients with arthritis and its related factors. Data were collected from 100 people who suffered from arthritis in Seoul. Busan, Daegu, Daejun, Junjoo, and pohang from April 2, 2000 to July 31, 2000. The results of this study are summarized as follows : 1. 6L0% of the subjects were female. The incidence rate of arthritis was higher in the higher age group, lower educated group, and thinner group. In case of male, the incidence rate was higher in the groups of single, residents in big cities, and technicians. In case of female, it was higher in the groups of the married, residents in towns or villages, and housewives. 2. According to the parts of arthritis, knee joint covered 67.4% and backspine joint covered 9.0%. The incidence rate of arthritis was higher in the groups of forties, housewives, single, irreligious people, residents in towns and villages, primary school graduates, thin people, and walk exercisers. 3. The arthritis patients felt pain most when they stood up (31.5%). According to the time when they felt pain most, the time when they were active during daytime was 31.5% and nighttime was 29.8%. When they got up in the morning was 22.4%, while 10.9% felt pain all cay long. 4. they had arthralgia knees and cramp in crook of the knees (21.8%). Their knees ticked when they moved (21.1%). The had to rest hands on anyplace when they stood up (18.7%) and they could not completely unfold their knees. 5. The medical institutions which diagnosed them showed significant difference in the variables of sex, age, marital status, religion, place in residence, education level, economic status, obesity level, exercise, parts of arthritis, and posture of feeling pain. from above results, it can be concluded that it is necessary to develop appropriate medical treatment on the basis of the respondents' socio-democraphic characteristics, pain parts, period of having a pain, satisfaction level with treatment and its related factors. Therefore, related professionals and organizations must develop education program for prevention of arthritis in order to educate them.

        초음파를 이용한 교근의 단면두께 측정의 재현성에 대한 연구

        정기정,한원정,김은경 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.2

        Purpose : To determine if ultrasonography is a reliable technique to assess masseter muscle sites within intra- and interobserver and the scanning level and/or the muscle condition affect local cross-sectional dismension (LCSD) measurements of masseter muscle. Materials and Methods : 10 subjects without sign and symptom of temporomandibular disorders and missing posterior teeth were examined by ultrasonography. Bilateral ultrasonographic examinations were performed with a linear (B-scan) 7.5 MHz small-part transducer to register LCSDs of the masseter muscle on three different levels. Scans were made on relaxed and clenching condition. Three oral and maxillofacial radiologists measured at two sessions with a time interval of at least 5 minutes. Results : Variables such as ‘condition’ and ‘level’ had a significant effect on muscle measurements (p>0.05). There was no significant difference betwee‘sessions’(p>0.05) and ‘observers’(p>0.05). LCSDs on lower scan level were significantly thinner than those on upper and middle level. Those on clenching condition were significantly thicker than those on relaxed condition (p<0.05). The scanning level with the highest reproducibility was middle with clenching condition (ICC = 0.90, MSE = 0.55%). Conclusion : The data suggested that ultrasonography was a reliable method for measuring LSCD of masseter muscle in intra- and interobserver and middle scan level showed the most reliable data.

        Double pyrolus, one of the relatively rare anomalies of the gastrointestinal tract, is a fistulous communication between the gastric antrum and the duodenal bulb. The first case of a double Pylorus was reported in 1969 by Smith, since then several cases have been reported. Recently, as the frequency of examining upper gastrointestinal series and endoscopy increases, it occurs more frequently and a few cases have been described in our country. According to the reports previously published, it resulted only from cysts, diverticla, atresia, band, membrane malformation of the pylorus, however, it might be also caused by penetration, complication of peptic ulcer. We report a case of double pylorus in a 67-year old man with prolonged administration of corticostetoids due to lumbago who has complained epigastric pain which was confirmed by endoscopy and biopsy.

        Adult polycystic kidney disease(APKD) usually accompanies with renal and extrarenal manifestations and liver cysts are present in aproximately 30% of patients with APKD. Kidney cysts often accompany with hemorrhage, rupture, infection, however, liver cysts are usually asymptomatic and do not impair liver function. Rare complication of liver cysts in patient with APKD include portal hypertension with bleeding esophageal varices and hepatic failure with encephalopathy. But, in APKD patient, infection of liver cysts without infection of renal cysts is extremely rare. We report a case of infected liver cyst in a patient with APKD who has complained generalized abdominal pain and high fever which was confirmed by ultrasound and aspiration. The patient was treated successfully with repeated aspiration and systemic antibiotics.

      • 퍼지제어를 이용한 유도전동기 드라이브의 효율 최적화

        정동화,이정철,박기태,이홍균 순천대학교 1999 순천대학교 자연과학논문집 Vol.18 No.2

        Efficiency optimization of an indirect vector controlled induction motor drive is proposed. The loss models are used in the validation of the fuzzy logic based on-line efficiency optimization control. At steady state, the fuzzy controller adaptively changes the excitation current on the basis of measured input power, until the maximum efficiency point is reached. The pulsating torque, due to flux reduction, has been compensated by an ingenious feedforward scheme. During transient state, rated flux is established, to get the best transient response. Through a comprehensive simulation study, the results confirmed the validity of the proposed method.
