Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.

강석헌,박상운 大韓神經精神醫學會 1989 신경정신의학 Vol.28 No.4

To determine the role of family crisis in the development of psychiatric emergency and to find the clinical characteristics of the patients, the author reviewed hospital records of 422 psychiatric patients who visited the emergency room of Kyungpook University Hospital during the past two years from June 1, 1986 t0 May 31, 1988 The results were summarized as follows; Among the total 422 patients, 139 cases(31.4%) proved to have a history of family crisis ; Most frequent problems were marital conflict(52.6%) and about two thirds of the cases were female in their thirties and twenties. Most of the patients were diagnosed as conversion disorder with characteristic somatization problem. Symptoms of parahysis or paresthesia, altered consciousness and emotional excitement with aggressiveness were commonly found. Only 12.9% of patients could be treated through hospitalization, 7.2% of the patients visited out-patient department and the rest refused the medical advice of follow up visit as out-patient clinic basis. Chinical vignetle of 5 typical cases were also presented. Finally, the author discussed the family crisis of the patients in relation to the Korean cultural value systems in transition and stressed the need for intensive in this field.

김성균,강병훈 梨花女子大學校 法學硏究所 2017 法學論集 Vol.21 No.3

소멸시효가 완성되면 그 효과로 권리가 소멸하나 진행하던 소멸시효는 일정한 사유가 존재하면 더 이상 진행되지 않고 중단되어 시효의 대상이 된 권리는 존속하게 된다. 이처럼 소멸시효 완성 여부는 권리의 존부와 관련되어 있어 소송의 승패를 좌우하게 되는 매우 중요한 법률적 문제이다. 본고에서는 소멸시효 중단에 관한 사유 그 중에서도 ‘채권집행’이 소멸시효중단에 어떠한 영향을 미치는지에 대하여 분석하고자한다. 먼저 집행채무자의 제3채무자에 대한 채권이 압류된 경우에 이에 의한 집행채권의 소멸시효에 관하여 살펴보았다. 여기서는 집행채권이 압류에 의해 시효중단이 되는 경우 그 시효중단의 시기와 종기가 언제인지 여부가 쟁점이므로 이를 중심으로 검토하였다. 나아가 압류가 취소되는 경우에 그것이 시효중단의 효력에 미치는 영향에 대하여 민법 제175조를 중심으로 분석하였다. 또한 집행채권의 소멸시효가 중단되는 사유 가운데 ‘청구’ 그 중에서도 ‘최고’에 의해 시효가 중단되는지 여부는 특히 압류가 취소되는 경우에 있어서 중요한 문제로 부각되고 있어 이에 대하여도 논의하고자 하였다. 그리고 단순 최고가 아닌‘재판상 최고’로서의 효력을 인정할 수 있는지에 대하여도 논의하였다. 다음으로 채권집행 절차에서 배당요구의 방법으로 참여한 채권자의 배당요구 채권이 압류 또는 최고에 의해 시효가 중단되는지 여부를 검토하였으며, 부동산 강제 집행에서 문제되는 채권신고가 소멸시효의 중단에 미치는 영향에 대하여도 간단히 살펴보았다. 마지막으로 채권집행이 이루어지는 경우에 피압류채권의 소멸시효 중단의 문제에 대해서 살펴보았다. A right is extinguished due to the effect if completion of extinctive prescription is made but the ongoing extinctive prescription does no more proceed and the right still exists if there is a certain reason. Like this, completion of extinctive prescription is a very important legal issue determining the outcome of a lawsuit because it is related to existence of a right. Among reasons for suspension of extinctive prescription, this study reviewed influence of ‘claim execution’ on suspension of extinctive prescription. First, it investigated the extinctive prescription of claim execution by attachment. Here, in the case of suspension of extinctive prescription, its time and expiration are the main issue and therefore, this study reviewed the issue. Further, it conducted a review mainly on the article 175 of the Civil Law with respect to influence of attachment cancellation on suspension of the extinctive prescription. Next, whether claim execution is suspended by a ‘notification’ out of ‘claims’, one of the reasons for suspension of extinctive prescription, becomes an important matter in the case of attachment cancellation and therefore, it also discussed the matter. Among reasons for suspension of extinctive prescription, it also analyzed issue of the suspension by a judicial notification out of ‘notifications’, one of the reasons for suspension of the extinctive prescription, and reviewed whether credit of request for dividend by a creditor participating in claim execution procedures in a manner of request for dividend is suspended by an attachment or a notification, and it finally intended to analyze suspension of the extinctive prescription of attached claim if credit execution is made.

유기박막 광도파로형 바이오(칼슘이온)센서의 개발

강신원,박이순,김성훈,김창원 경북대학교 센서기술연구소 1955 연차보고서 Vol.1995 No.-

본 연구는 고감도, 빠른 응답특성 및 넓은 센싱범위를 갖는 능동형 유기박막 광도파로형 칼슘이온센서를 개발하였으며, 이와 병행하여 중성 ionophore와 함께 특정 음이온 선택성의 색소(LAD : lipophilic anionic dye)를 설계·합성을 하였다. 유기박막 광도파로형 칼슘이온센서는 감지막 자체를 박막광도파로화 함으로써 빠른 응답시간과 고감도의 특성을 가졌으며, 514㎚ 광원에서 10^-6∼1M의 범위의 Ca^++ 의 농도를 측정할 수 있었다. 또한 새로이 합성된 LAD의 칼륨이온선택성을 분광측정으로 평가한 결과, 광이온센서(optode)들의 변색성 이온감응물질로서 사용이 가능함을 확인하였다. A new approach to the design and construction of thin-film optical waveguide Ca^+2 sensor has been developed by using a copolymer matrixed membrane that incorporates a cation-selective neutral ionophore, H^+-selective neutral chromo-ionophore, and lipophilic anionic sites in the same plasticized copolymer membrane. This sensor is based on absorption measurement, and it makes use of host molecules that change their optical properties through an actual ion-sensitivity recognition process. In parallel, the high ion-selective lipophilic anionic dye(LAD) was synthesized and evaluated. Proposed ion sensor, utilizing thin film membrane which is the waveguide itself, exhibited rapid response time and high sensitivity. And sensor could detect a wide range of Ca^++ concentrations ranging from 10^6 ∼ 1M by measuring the absorbance change at 514㎚ of light. The newly synthesized LAD showed its potential applicability as chromoionophore for optodes and/or thin-film optical waveguide sensors.

이상윤, 김재용*, 임형준, 윤기정, 최홍렬*, 고상백**, 강대희, 조수헌 대한산업의학회 2001 대한직업환경의학회지 Vol.13 No.2

목적 : 작업장에서의 누적소음노출값과 혈압의 변화 사이의 관계를 관찰하기 위한 단면 연구를 시행하였다. 방법 : 소음발생 제조업체의 남성근로자 중 건강진단 자료, 설문지 자료, 인사기록이 모두 갖추어진 852명을 연구대상으로 하였다. 작업장 소음측정값은 34개 지점에서 측정된 작업환경 측정 보고서 값을 사용하였고, 혈압은 건강진단시 측정한 수축기 혈압과 이완기 혈압 각각의 평균을 이용하였다. 가능한 교란변수들을 건강진단시 설문조사를 통하여 조사하였다. 근로자의 근무기간과 근무했던 작업부서의 소음노출값을 이용하여 누적소음노출값을 추정하였고, 이에 따라 전체 연구대상 근로자를 저소음노출군, 중등도소음노출군, 고소음노출군, 과다소음노출군으로 구분하였다. 누적소음노출값으로 구분한 소음노출군 사이에 평균 수축기 혈압 및 이완기 혈압의 차이가 있는 지를 나이, 비만도지수, 혈중 콜레스테롤값, 고혈압의 가족력, 흡연력, 음주력 등의 가능한 교란변수들의 영향을 통제한 상태에서 비교하였다. 결과 : 가능한 교란변수들을 보정한 상태에서 저소음노출군에서 과다소음노출군으로 갈수록 수축기 혈압 및 이완기 혈압의 증가가 있는지를 관찰하기 위해 일반선형모델을 이용하여 분석하였을 때, 수축기 혈압 및 이완기 혈압 모두 소음노출군이 혈압 변화의 유의한 설명변수였고, 수축기 혈압 및 이완기 혈압 모두 저소음노출군에 비해 과다소음노출군이 각각 2.1 mmHg, 2.7 mmHg 만큼 높았다. 결론 : 이는 만성적으로 누적된 고소음에의 노출로 인하여 혈압 상승의 가능성이 있음을 시사한다. Objectives : The association of workplace cumulative noise exposure and blood pressure was investigated in this study using cross-sectional design. Methods : The study population comprised 852 manufacturing male workers of whom occupational health examination data, questionnaire and personnel records were available. Workplace ambient noise monitoring data was used for calculating individual cumulative noise exposure level. Mean of each systolic and diastolic blood pressure of occupational health examination data was used for individual systolic and diastolic blood pressure level. Possible confounding variables including family history of hypertension, smoking habit, alcohol drinking habit were collected by questionnaire. On the basis of job location and duration of work at the location, a cumulatlve time-weighted average noise level was calculated for each workers. According to this cumulative noise exposure level, each study subject was categorized as low noise exposure group, moderate noise exposure group, high noise exposure group, very high noise exposure group. Among noise exposure groups, mean of systolic and diastolic blood pressure was compared after adjusting possible confounding variables such as age, body mass index, serum cholesterol level, family history of hypertension, smoking history, alcohol drinking habit. Results : After adjusting possible confounding variables, noise exposure group was signnificant explanatory variables for both systolic and diastolic blood pressure, and mean of both systolic and diastolic blood pressure of very high exposure group was higher than that of low exposure group. Conclusions : These findings suggested that the high cumulative noise exposure might elevate the blood pressure.

Very large PPC effect(σ_ppc/σ_A=10^5) in doping-modulated npnp a-Si: H superlattices could be obtained. B and P atoms, respectively, diffuse and so some parts compensated. Therefore, annealing activation energy of E_a=0.67eV is larger than one of reference n-type sample of E_a=0.26eV and annealing dark conductivity of σ_A=4×10^-[ohm cm]^-1 is lower than that of n-type reference sample of σ_A=2×10 exp (4)[ohm cm]^-1. From this results, very large PPC relatively have obtained. In this paper, we have observed that PPC effect depends on temperature and exposure time. On the basis of the experimental results, we discuss the existing models.

변압기 보호를 위한 Fuzzy Decision Making 알고리즘

강대훈,이승재,강상희,권태원 明知大學校 産業技術硏究所 1999 産業技術硏究所論文集 Vol.18 No.-

This paper presents a new fuzzy decision making algorithm for power transformer protection based on the Dempster-Shafer's theory of evidence. To distinguish internal faults from other transient states, four input variables are selected. Each time dependent fuzzy rule base is composed of twelve fuzzy if-then rules associated with their basic probability assignments (BPAs) for singleton - or compound-support hypotheses. Dempsters rule of combination is used to process the fuzzy rules and get the final decision. The proposed algorithm also has a capability to identify the inrush, over-excitation and external fault with current transformer (CT) saturation besides the internal fault.
