The purpose of this study was to examine the content validity of DSM-Ⅲ-R personality disorder(PDs). A 3-point rating scale of 150 preliminary diagnostic criteria including 95 DSM-Ⅲ-R PD diagnostic criteria was sent to psychiatrists. Each item in this scale was rated by psychiatrists(n=101) in term of prototypicality to every DSM-Ⅲ-R PD. The results show that each PD criteria set of DSM-Ⅲ-R was registered high level of interrater consistency and items listed in the DSM-Ⅲ-R were, for the most part, rated as very prototypical to their DSM-Ⅲ-R diagnosis. Some criteria were, however, not rated to characteristic features to their DSM-Ⅲ-R diagnosis. 11 items of DSM-Ⅲ-R diagnostic criteria scored high not only to their DSM-Ⅲ-R diagnosis but also other diagnosis. 16 items rated as high prototypicality item of other diagnosis. Another 16 items seemed not to be appropriate to any of DSM-Ⅲ-R PD diagnosis. These results suggest that the content validity of the DSM-Ⅲ-R personality disorder is not so high.

Because micro-cavity type optical fiber Fabry-Perot interferometric pressure sensor itself play a signal processing role, it has electrical safty and is immune to EMI(electro-magnetic interference). And it also has high sensitivity in the measured range and low sensitivity dependence on the thickness of diaphragm. Therefore it has many advantages, so it will be applicable to accelerate sensor, flow sensor, and microphone, etc.. In this paper, using silicon anisotropic etching technique and fiber optic sensing technique, micro-cavity type optical fiber Fabry-Perot interferometer was formed and a highly sensitive pressure sensor was fabricated. The fabricated micro-cavity type optical fiber Fabry -Perot interferometric pressure sensor showed repeatedly good output characteristics.
BONDGRAPH 모델링 방법을 이용한 PDFF제어기에 관한 연구
이병규,신위재 경남대학교 신소재연구소 1995 論文集 Vol.5 No.-
오늘날 산업용 기기에는 제어성능이 양호한 직류서보모타가 속도 및 위치제어에 절리 사용되고 있으며, 직류서보모타를 이용하는 서보시스템에 있어서 관성이나 외란 등에 의한 파라메타 변화에 높은 적응성을 갖는 제어시스템이 요구되고 있다. 본 논문에서는 일반적인 PDF(Proportional Derivative Feedback) 제어기에 전향(Feedforward)을 보상시킴으로서 시스템의 위상여유각을 조절 할 수 있는 PDFF(Proportional Derivative Feedback and Feedforward loop)제어기를 본드그래프로 구성하였고, 본드그래프 시뮬레이션을 통해 신속하고 편리하게 제 계수를 설정할 수 있었고, 또한 DC 서보계의 해석에도 본드그래프가 유익한 TOOL이됨을 확인하엿다. This PDFF controller show the optimal transition response that variation of compensated cofficients. Therefore bondgraph modeling method is confirmed that the speedy and convenient tool through simulation procedure. PDFF controller have abtained the speed response more than PDF. We could find another fact that the PDFF controller have been more improved in the adaptability to speed by means of the process of the bondgraph simulation.

This study was performed to identify personality trait of patients with methamphetamine and alcohol abuse by analyzing MMPI profiles. 93 methamphetamine abuse patients, 59 alcohol abuse patients and 52 healthy subjects completed MMPI. Each MMPI profile in three groups was analyzed by F-test and discriminant function analysis. Alcohol abuse patients showed higher scores n F, Sc(8), and Si(0) profiles of MMPI than the patients with methamphetamine abuse. 3 variables(F, Si, Pd) were discriminated in there two groups. Methamphetamine abuse patients showed higher cores in F. K. Hs(1), Hy(3), Pd(4), Pa(6), Sc(8), and Ma(9) profiles of MMPI than the normal controls. 5 variables (Pa, Pd, Si, K, L) were well discriminated in these two groups. The alcohol abuse patients showed higher scores in F, Hs(1), D(2), Hy(3), Pd(4), Mf(5), Pa(6), Pt(7), Sc(8), and Ma(9) profiles of MMPI than the normal controls, but lower scores in K subscale, 3 variables(F, Pb, Pa) were well discriminated in these two groups. Specially these results indicated that alcohol abuse patients had more psychotic symptoms than methamphetamine abuse patients. These results may suggest that addicted individuals have personality traits to be drug addicts, but it was unclear that these results were ue to predisposing personality traits or results of drug abuse.
고등학교 정치교과서의 정치교육내용 비교 분석 : 『정치·경제』·『정치』교과서의 비교를 중심으로 『Politics·Economics』and 『Politics』

The purpose of this study is to compare and analyze the political education contents in a viewpoint of conservative and innovative function between 『Politics』and 『Politics·Economics』of the high school textbooks, those have been used in 5th and the 6th curriculum. First of all, this study made an analytic model about the political education context of the high school textbooks on the basis of many theories about the political education for students. Second, it made criteria about the usefulness and the harmony between conservative and innovative function for political education in a socio-functional point of view, and also, briefly reviewed the process of undergoing changes in the social studies curriculum until now. Third, according to the criteria, it examined the contents of the politics textbooks of the high school and analysed the frequencies of contents in each political education areas. The contents of political education in 『Politics·Economics』 showed more tendencies of a rightist direction than those in 『Politics』. In conclusion, the study is suggesting it is critical for students to teach organization culture, discipline and to maintain the society, but the recent political education needs to teach them both conservative and innovative area to a adjust themselves to a changing society.
N/O/N 박막 다이아프레임을 이용한 광섬유 압력센서의 제작 및 그 압력특성
유양욱,김명규,박동수,김창원,김진섭,이정희,손병기 경북대학교 센서기술연구소 1995 센서技術學術大會論文集 Vol.6 No.1
The 0.6 μm N/O/N triple layer, Si_(3)N_(4)(150 nm)/SiO_(2)(300 nm)/Si_(3)N_(4)(150 nm), was deposited on silicon substrate and the N/O/N thin film diaphragm was formed using anisotropic etching technique. The stress of the formed diaphragm was very small with temperature variations. Combining this diaphragm and the optical fiber, intensity-type pressure sensor was fabricated and its pressure characteristics were investigated. The relation between the optical output power, inversely proportional to the deflection of the diaphragm, and the applied pressure was almost linear in 0~77 torr range.

본 연구는 p-변량 자료의 구조를 파악하고, 관련이 있는 변수들을 p보다 적은q-차원(p≥q)으로 축소하였을 경우, 자료에 존재하는 군집수의 예측에 어떤 영향이 있는지 비교 분석하였다. q-차원으로 축소시, 주성분인자분석을 사용하였다. Cluster analysis is a primitive technique in which no assumptions are made concerning the data structure. A method predicting the number of cluster by using dimensional reduction is suggested with Rand's(1971) C? k=1,2 …, n-1, statistic. The principal factor analysis is used to reduce original p-variables into new q-variables(p≥q). simulation is conducted to compare the suggested method.
