연구배경 : IOS 혹은 FOT는 외부의 loudspeaker에서 발생하는 기류의 진동을 자발호흡에 부가시킴으로써 발생하는 압력의 변화를 분석하여 폐기능을 평가하는 방법으로, 일반적인 폐기능검사 방법들과는 달리 노력성 호기방법이 필요치 않고 자발성 상시호흡에서 검사가 가능하다는 장점이 있다. 또한 microprocessor 의 도입으로 Fourier 변환법에 의한 복잡한 신호 분석이 가능해 지면서 주파수에 따른 호흡기계의 impedance를 실측부분 (Rrs : resistance) 과 추정부분 (Xrs : reactance)의 두요소로 보다 깊이 파악할 수 있게 되었다. IOS의 임상적 이용은 소아의 폐기능검사, 역학적 연구, 소기도질환의 확인, 유발검사 등에 장점이 있다고 알려져 있다. 그러나 흡연자에서 발생하는 소기도 폐쇄 또는 조기 기도폐쇄를 확인하는데 있어서 IOS의 역할에 대한 연구 보고는 논란이 있어 왔다. 이에 본 연구에서는 흡연자에서의 조기 기도폐쇄를 측정하는 방법으로서의 IOS가 갖는 임상적 유용성을 검증해보고자 하였다. 방 법 : 종합검진센타를 방문한 남자중에서 노력성 호기성 폐활량 측정 검사상 정상 소견을 보인 356명($40.6{\pm}9.7$세)을 대상으로 IOS(Jaeger company : Version 4.1)을 시행하여 흡연자군 (234명 : $40.2{\pm}9.3$세)과 비흡연자군(122명 : $41.5{\pm}10.6$세)으로 구분하여 양군간에 두가지 검사볍 지표들에 대한 유의성을 검증하였다. 결 과 : Spirometry 지표인 FVC, FVC%pred, FEV1, FEV1%pred, FEV1/FVC, PEF, PEF%pred, FEF25~75%, FEF25~75%pred, FEF50%, FEF50%pred 등은 모두 흡연자군과 비흡연자군간에 유의한 차이가 관찰되지 않았다. IOS 지표중 total resistance(흡연자군 : 비 흡연자군=$2.58{\pm}1.71$ : $2.22{\pm}1.20$), peripheral resistance($1.47{\pm}0.10$ : $1.25{\pm}0.62$), bronchial compliance($0.47{\pm}0.16$ : $0.44{\pm}0.12$) 등은 양군간에 유의한(p<0.05) 차이가 관찰되었으나 central resistance와 lung compliance는 유의한 차이가 관찰되지 않았다(단위는 resistance=hPa/l/s ; compliance=1/hPa). 주파수에 따른(5, 10, 15, 20, 25, 30, 35Hz) Rrs은 양군간에 유의한 차이를 관찰할 수 없었고, Xrs는 낮은 주파수, 즉 X5($-0.76{\pm}0.48$ : $-0.62{\pm}0.28$) 와X10($-0.15{\pm}0.33$ : $-0.06{\pm}0.19$)에서 유의한 차이를 관찰할 수 있었다(단위는 hPa/l/s). 결론 : IOS은 흉연자와 비흡연자의 조기폐쇄를 확인할 수 있는 검사법이라고 판단되며, total resistance, peripheral resistance, bronchial compliance, 그리고 5Hz와 10Hz 의 낮은 주파수에서의 Xrs가 유용한 지표라고 판단된다.

It is well recognized that the ultrasonic methods is one of the most common and reliable nondestructive testing(NDT) methods for the quantitative estimation of defects in welded structures. However, NDT techniques applying for adhesively bonded joints have not been clearly established yet. In this paper, the detection of interface crack by the ultrasonic method was applied for the measurement of interfacial crack length in the adhesively bonded joints of double-cantilever beam(DCB). The optimum condition of transmission coefficients in the adhesively bonded joints and it's experimental accuracy by the ultrasonic method have been investigated. The experimental values are in good agreement with the computed results by boundary element method(BEM) and Ripling's equation.

More accurate and fast inspection method for mechanical parts and structure is required to guarantee the safety. Conventional methods using compliance method, eddy current method, ultrasonic wave, acoustic emission for non-destructive testing in mechanical parts and structure have been performed as the method of contact with objects to be inspected. With this reason these methods have been taken relatively much time, money, and manpower. In this study, in order to overcome these shortcomings, we used In-plane Electronic Speckle pattern Interferometry(In-plane ESPI) that was full-field measurement and noncontact method. We detected the cracks of the specimen at a real time and measured the length of the crack by using In-place ESPI system. Finally, we compared this results with conventional microscope method.

This study seeks to determine the effect of the application of accounting information system (AIS), internal control system, and human resource (HR) competency on the quality of local government financial statements (FS). This study uses agency theory and compliance theory. Agency theory is used to explain that there is a link between the society as the principal and the government as the agent. Compliance theory is a theory, which states that every agency is obliged to comply with regulations because the law-drafting authority has the right to dictate behavior. The population in this study were employees of the financial division of local government organizations in one of the districts in Central Java, Indonesia. The total samples in this study was 106 respondents. The data used are primary data taken from distributing questionnaires to respondents. The method of analysis used to test the hypothesis was multiple linear regression analysis. The results of hypothesis testing indicate that HR competency has an effect on the quality of FS; however, the application of AIS and internal control system has no effect on the quality of FS. The implication of this research underlines the importance of HR competency to improve the quality of local government FS.

Purpose: The purpose of the study was to compare recipients' health behavior, attitude to using medicaid, medication compliance, and the changes in hospital cost and visit-day of in-patient and out-patient care between tele-care regions (TCR) and general care regions (GCR) in Korean medicaid. Method: The design of the study was ex-post facto comparing recipients in TCR and GCR. The sample included 625 persons in TCR and 410 persons in GCR. To collect materials, the case manager interviewed recipients of medicaid and filled out questionnaires which were analyzed through SAS/PC 9.1. Results: In studying health behavior and medication, compliance was not significant. However, the attitude to using medicaid was significantly more positive in TCR than in GCR. In out-patients, the change of hospital visit-day was not significant between TCR and GCR, but TCR showed a reduction in hospital cost compared to GCR. For in-patient recipients, GCR showed a greater reduction in changes in hospital cost and visit-day compared to TCR. Conclusions: The results of the study show that attitudes to using medicaid via telephone are positive and results are more effective than hospital visit consultation, and the cost of out-patient care could be reduced.

The purpose of this study was to investigate the influencing factors on health behavior among patients with coronary artery disease. Method: The subjects were 95 patients who visited the out-patient department of a university hospital for follow-up. The four health belief concepts (motivation, benefit, barrier, seriousness), general self-efficacy, health behaviors on medication, diet, exercise, stress management, smoking, and drinking were measured. Result: There were significant differences in the health behavior scores of subjects according to family support and the experience of surgical procedure. Subjects were found to have a high degree of compliance in taking medication. However subjects reported the lowest degree of compliance in regular exercise. In the multiple regression analysis, surgical procedure and motivation were significant predictors to explain diet. Motivation and barrier were significant predictors to explain exercise. Self-efficacy, motivation and family support were significant predictors to explain stress management. Family support and seriousness explained 16% of variance in drinking. Also, family support explained 30% of variance in smoking. Conclusion: Since predicting factors on each health behavior indicator were different, then nurses should consider these differences to construct strategy enhancing patient's recovery.

본 논문에서는 cellular 이동통신용 기지국 안테나와 같이 사용되는 파장에 비해 비교적 부피가 큰 해석 대상 체의 근거리장에서 전력 밀도를 계산한 내용을 다루었다. 현재 국내에서 cellular 이동통신 기지국용 안테나로 널리 사용되는 판넬형 섹터 안테나를 모델링하고 FDTD 계산법으로 reactive 근거리장의 전자계 분포를 계산하였으며 near to far 변환 통하여 원거리장의 안테나 이득을 구하였다. 그리고 radiating 근거리장의 전력밀도를 계산하기 위하여 원거리장의 이득을 이용하여 gain-based 모델을 적용하였다. 끝으로 radiating 근거리장의 전력밀도 계산 결과와 ICNIRP guideline의 전력밀도에 대한 일반인 및 직업인의 노출 제한 값을 고려하여 인증 거리(compliance distance)를 산출하였다. Gain based 모델을 이용한 계산 결과를 표면주사(surface scanning) 방식을 이용한 전력밀도의 측정 결과와 비교한 결과 주방사 방향의 중심 위치에서 계산된 값은 gain based model을 이용할 경우 -14.55 ㏈m이고, 측정된 값은 -15.75 ㏈m으로 케이블 및 커넥터의 손실을 감안하면 매우 정확한 것으로 나타났다.
