Objectives : To observe the effect of acupuncture and nerve block combination treatment on adhesive capsulitis patients. Metbods : 59 voluntary patients were randomly assigned to acupuncture treatment group(E group ,n=22), nerve block treatment group(W group, n=17) and acupuncture and nerve block combination treatment group(EW grouP, n=20). The E group received acupuncture treatment on LI15, TE_(14), GB_(21) and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection twice a week for 4 weeks. The EW group received the same treatment as the W group and after 5minutes of rest, successively received the treatment identical to that of E group. AU three groups were instructed to practice groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after 1, 2, 3 and 4week treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM), the patient's treatment satisfaction measured by Visual Analogue Scale(VAS) and Digital Infrared Thermographic Imaging(DITI) were used as assessment tools. The obtained data were analyzed and compared. Results : The E group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Adduction and Extension improved significantly(p<0.05). The W group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Abduction and Extension improved significantly. The EW group showed significant improvement(p<0.05) on CSA, SPADI and VAS. As for ROM, Adduction, Abduction, Extension and Flexion improved significantly. The improvement of CSA, VAS and Abduction ROM in the EW group was significant1y(P<0.05) superior compared to the groups treated with single type of treatment. Conclusion : It is suggested that acupuncture and nerve block combination treatment for adhesive capsulitis patients is more effective than the two single treatments. Through further studies, the acupuncture and nerve block combination treatment model may be developed into East-West Collaboration Model in treating adhesive capsulitis.

Toxicity of LFWS to A549 revealed that more than 50% inhibition of growth at LFAS conentration of 10× after 72 hours. Concentration of LFWS at 10× and 5× showed more than 50% inhibition of growth with EATC, Hepalclc7, HeLa and A549. In morphological study, the number of cells were decreased, and the shape of cells was round form in EATC, Hepalclc7, HeLa, and A549.

臨床診斷과 手術診斷의 比較 調査

신종연,남송현 서울保健大學 1985 論文集 Vol.5 No.1

1979년 1월부터 1984년 12월까지 5년동안 서울시내에 위치한 한 종합병원(200병상) 내과로 입원하여 외과로 전과된 例(n=75)를 대상으로 하여 내과에서 전과전에 내려진 임상진단명과 수술후 확진된 진단명을 비교 조사하여 다음과 같은 결론을 얻었다. 1. 年度別 전과율은 평균 2.8%로 75列이며 오진율은 전과例의 32%인 24例이었다. 年度別오진율의 감소현상은 없었으며 남녀간에도 오진율의 차이는 없었다. 2. 오진예의 계절별 분포는 여름중에서도 7월이 가장 높았으며, 가을이 가장 낮았다. 3. 오진예의 연령군별 분포는 50代에서 가장 많았으나 오진율에 있어서는 연령군간에 특이한 경향이 없었다. 4. 내과에서의 입원기간이 2日~3日사이에 오진율의 50%가 나타났으나, 正診率과 誤診率과의 관계에서 입원기간은 통계적으로 有意한 상관관계를 나타내지 않았다. 5. 의료비 지불방법이 의료보험인 환자의 37.8%, 일반환자의 26.3%가 오진으로 나타나 보험환자의 경우가 다소 높았으나 통계적으로 有意하지 않았다. 6. 오진의 정도를 분류하면 오진24例(32%)중 수술이 필요치 않았던 경우는 8例(10.6%)이며, 나머지는 어차피 수술을 했어야 한 경우이나, 5例(6.7%)는 질환장기가 정확히 진단되지 못했던 경우이고, 11例(14.7%)는 질환장기는 맞았으나 그 장기의 질병명이 다소 다르게 진단되었던 경우이다. 7. 계통별 오진예는 소화기질병(62.5%), 신생물(16.6%) 順이었으며, 장기별 오진율은 간(66.6%), 담낭(38.9%), 장(33.3%), 위장(15.8%) 順으로 간질환은 전과예가 적은데 비하여 오진율이 높았고, 위장질환은 전과예가 많은데 비해 오진율이 낮았다. 8. 오진의 원인을 살펴보면 담당의사의 판단 오류로 인한 오진이 51.2%로 가장 높다. 이중환자의 증세를 정확히 판단하지 못한 경우가 28%, 검사결과의 판단오류가 20.5%이었다. 오진의 개념과 범위를 정의함에 따라 오진율의 비율은 많은 변이를 나타낸다. 본 조사에서 대상이 되었던 전과수술예란 수술을 위하여 외과로 전과했던 경우로서 오진의 개념을 수술이 과연 필요했는가에 촛점을 맞춘다면, 본 조사결과에서는 총 전과예 75例중 10.6%에 속하는 8例만이 해당되므로 그 수준은 소규모 종합병원에서는 만족할만한다 하겠다. This study was conducted to: 1) determine the consistency of post-operative, pathological diagnosis as conpared to clinical diagnosis: 2) indentify the characteristics of patients and diagnosis subject to diagnostic discrepancy: and 3) analyze the apparent reasons on such discrepancies. The date was obtained from a review of one hospital medical records of surgical patients transferred from medical department (n=75) during 5 years-period (1979.1-1984.12) The results were as follows. 1. Misdiagnosis was observed in 24 cases (male 13, female 11) out of 75 transferred cases, with diagnostic error of 32 %. 2. Seasonal variance is noteworthy that the highest incidence of misdiagnosed cases occurred during June particulary in Summer. 3. Misdiagnosed cases were highest in the group aged 56 to 59, but there were no marked trend in diagnostic error rate according to age group of patients. 4. Misdiagnosis were occurred freguently in the patient group transferred after short termed hospitalization in internal medical department but no relationship was found between the diagnostic error rate and length of stay in internal medical department. (P>0.05). 5. There was a tendency that insurred patients seemed to have higher rate of misdiagnosis than non-insurred patients had. But this result was not statistically significant (P>0.05). 6. Misdiagnosis which led to carry out unnecessary operation were 8 cases (10.6%). 7. Diagnostic error seemed to be due not so much the lack of medical knowledge as to deficiencies of medical judgement, alterness and throughness.

내용기반 분류에 의한 비디오 검색 시스템 설계

배종식,남윤성,양동일,최형진 강원대학교 정보통신연구소 2006 정보통신논문지 Vol.10 No.-

We suggest how to search news data by dividing structurely, by classifying meaningly, and by itemizing them by contents. The structural division divides the scene using correlative information between frames such as the distribution of the space brightness and the irregularity of brightness, and time relation etc. The meaning classification means to classify the detailed contents of news video as articles comparing special information extracted frame key frame with previous knowledge information. This study classifies the articles as the anchor's scene and the non-anchor's scene using the character that the progress of news is repeated centering around the anchor frames by periods. We get the non-anchor's scene to search the news data itemizing speech scene, interview scene and general scene, and classifying as articles. Also, we use the function of searching for summary by news icons and search the caption by processing the integration of caption, and design them to be able to search the news video quickly classifying news video as contents and indexing them.

VDT작업자에서 업무로 인한 정신사회적 스트레스에 대한 인지가 근골격계장애에 미치는 영향

백남종,하미나,조수헌,강대희,백도명,주영수,윤덕로,권호장 大韓産業醫學會 1996 대한직업환경의학회지 Vol.8 No.3

업무에 의한 정신사회적 스트레스가 근골격계 질환의 유병에 미치는 영향을 파악하기 위하여 전화안내원을 대상으로 단면적 조사연구를 수행하였다. 연구 결과 나이, 교육정도, 근무연한, 가사부담 등의 인구학적 변수는 근골격계질환의 유병에 영향을 미치지 않는 것으로 분석되었다. 정신사회적 스트레스 중 업무요구도가 높다고 느끼는 집단에서 그렇지 않은 집단에 비해 근골격계 질환의 유병률이 통계적으로 유의하게 높게 나타났으나 업무재량도나 사회적지지도는 근골격계질환과 유의한 상관관계를 발견할 수 없었다. 그러나 업무요구도는 높고 업무재량도는 낮다고 느끼는 '근무긴장도가 가장 높은 군'은 업무요구도는 낮고 업무재량도는 높다고 느끼는 '근무긴장도가 낮은 군'에 비해 근골격계 질환의 발생위험이 통계적으로 유의하게 높은 것으로 나타났다. 본 연구의 결과는 업무로 인한 정신사회적 스트레스에 대한 인지 정도에 따라 근골격계질환의 유병률이 달라짐을 시사하고 있다. 따라서 작업관련성 근골격계질환의 예방을 위해서는 기존의 인간공학적 접근 이외에 스트레스를 감소시키려는 노력이 동시에 진행되어야 할 것으로 생각한다. A cross-sectional study was conducted to assess the association between perceived occupational psychosocial stress at work and the work-related musculoskeletal disorder(WRMSD) among employees using video display terminals. The study included 111 female telecommunication employees from three companies at ChungBuk province. Cases of WRMSD were defined using symptom questionnaire and physical examination conducted by rehabilitation specialist. Information on demographics, individual factors, and perceived psychosocial stress, were obtained by self-administered questionnaire. For assessing perceived psychosocial stress, we used variables from 'job strain model' proposed by Karasek. Associations between perceived psychosocial stress and WRMSD were assessed by multiple logistic regression models. Forty nine(44% to the total) subjects met our operational definition for WRMSD. Age, seniority, housing load were not associated with WRMSD. Perceived psychosocial stress was associated with WRMSD[odds ratio=3.28, 95% confidence interval: 1.05-10.19]. This study suggests that perceived occupational psychosocial stress is related to the prevalence of WRMSD.

하옥남,이행남,이종인,윤치한 朝鮮大學校 機械技術硏究所 1998 機械技術硏究 Vol.1 No.1

본 연구에서는 글리세린 수용액(45%)을 사용하여 2차원 분기관 유로의 정상 층류에서의 분기부의 유동 상태를 알아보기 위하여 레이놀즈 수, 분기 각도, 유량 분배비등이 손실 계수에 미치는 영향을 실험으로 구하고, 다음과 같은 결론을 얻었다. 레이놀즈 수 100을 기준으로 하여 100 이하에서 T형과 Y형의 값은 직선적으로 감소하고, 유량 분배비의 영향은 적으며, 100 이상에서는 유량 분배비에 따라 거의 일정한 값, 즉 본관에서는 0.3∼1.3 지관에서는 1.70∼2.45의 수치에 접근한다. 그러나, 분기각의 영향은 레이놀즈 수 100 이하에서는 크지만, 100 이상에서는 매우 적어서 일정한 값, 즉 본관에서 액 0.9, 지관에서 약 1.8의 값을 갖는다. The purpose of this research is to study the characteristics of the dividing flow in the laminar flow region. Using glycerine-water solution(45%) for Newtonian fluid, this research investigates the flow state of the dividing tube in steady laminar flow region of the two dimensional dividing tube by measuring the effect of Reynolds number, dividing angle, and the flow distribution ratio on the loss coefficient. The results of the research is as follows. In T-type and Y-type tube, the loss coefficient of the glycerine-water solution decreases in constant rate when the Reynolds number is below 100. The effect of the flow distribution rate is negligible. But when the Reynolds number is over 100. the loss coefficient as to the flow distribution rate converges to a constant value. In the main tube the value lies in the range of 0.30-1.30. In the lateral tube the value lies in the range of 1.7-2.45. The effect of the dividing angle is considerable when the Reynolds number is below 100. But it is very small and converges to a constant value when the number is over 100: in the main tube approximately 0.9, and 1.8 in the lateral tube.

하종천,이협준,박봉환,김진숙,유대근,남상윤 전주대학교 자연과학종합연구소 2003 전주대학교 자연과학연구소 학술논문집 Vol.15 No.1

Background: Recombinant IFN-beta products have been approved for the treatment of several diseases. Recently, Inbionet, Co. has successfully developed rhIFN-beta product, Genebeta. This study was performed in a purpose of confirming the biological activity of Genebeta by comparison with another recombinant IFN-beta, Beneserin which was already approved. Methods: In vitro antiporliferative activity, regulation of MHC class I expression, antiviral activity, regulation of natural killer cell cytotoxicity were studied for functional comparison of these two rhIFN-beta products. Results: Proliferation assay data showed that two recombinant IFN-beta inhibited T cell and Daudi cell proliferation to a similar extent. When antiviral activity was compared, there was no significant difference between them. The treatment of these two rhIFN-beta also resulted in a similar level of upregulation of class I expression on the surface of A549 cells. Cytotoxicity experiment against tumor cells revealed that both of rhIFN-beta could enhance NK cell cytotoxicity to comparable level. Conclusion: All comparison data indicated that rhIFN-beta products, Genebeta and Beneserin have comparable potentials as a biological response modifier.

R22/R114 혼합냉매의 수평증발관내 강제대류 전열특성에 관한 연구

It was studied on the heat transfer characteristic of forced convection in horizontal tube using the pure refrigerant and non-azeotropic refrigerant mixture, and compared the heat transfer coefficient. The inside wall temperatures and the heat transfer coefficients of horizontal evaporation tube were obtained from the experiments using the pure refrigerant, R22 and R114, and the non-azeotropic refrigerant mixture, R22/Rl14. In case of the pure refrigerant R114, with increasing the quality, the local heat transfer coefficient of bottom of the tube was the highest value without being influenced by flow rate. In case of the pure refrigerant R22, in the low flow rate region the local heat transfer coefficient of bottom of the tube were the highest, and these were decreased as quality was increased, and in the high flow rate region the reverse results were obtained. In case of the refrigerant mixture, the local heat transfer coefficient of the bottom of tube were the highest regardless of flow rate. Two phase convection heat transfer coefficients of 76mol%R22-24mol%R114 refrigerant mixture were lower about 20% than these of Chen's.
