To investigate the clinical significance of the neurotic symptoms in schizophrenia, the author applied PSE(Present State Examination) on Screening Schedule to 153 schizophrenic patients who were fit for the aim of this study. The patients were divided into two groups to grasp the phenomenological characteristics as the group with neurotic symptoms (100 cases) and the group without neurotic symptoms(53 cases). Among 91 items except neurotic symptoms in PSE, 14 items were selected as significant under X²-test, and tried factor analysis with 14 items using SPSS/PC+. The results of this study were summarized as follows. 1. In the group with neurotic symptoms, 4 factors were extracted as slowness of speech and behavior and blunted affect factor, inappropriate answer and affect factor, delusion factor, and restricted and poverty of speech factor. In the group without neurotic symptoms, 5 factors were extracted as slowness speech and behavior and incoherence factor, inappropriate and poverty speech and self-neglect factor, delusion factor, inappropriate affect factor, and loss of affect factor. In the group of total patients, 4 factor were extracted as restricted and slowness of speech and behavior and blunted affect factor, delusion factor, inappropriate and poverty of speech and inappropriate affect factor, and incoherence factor. 2. In the group with neurotic symptoms, slowness of speech and behavior, inappropriate answer, blunted and inappropriate affect were the major symptoms and inappropriate answer and affect, delusion, restricted and poverty of speech were the minor symptoms. Among these symptoms, slowness restriction, poverty of speech and behavior, inappropriate answer and characteristic blunted affect were characterized by negative symptoms(i.e. defect state) which were frequent in chronic schizophrenia. 3. In the group without neurotic symptoms, slowness of speech and behavior, incoherence, and self-neglect were the major symptoms and inappropriate and poverty of speech, delusion, inappropriate and loss of affect were the minor symptoms. Among these symptoms, slowness and inappropriateness of speech and behavior, and characteristic incoherence and self-neglect were characterized by positive symptoms which were interpreted as less distorted reality than the group with neurotic symptoms in the process of schzophrenia. 4. In the group of total patients, restricted and slowness of speech and behavior, blunted affect and delusion were the major symptoms and inappropriateness, poverty and incoherence of speech, and inappropriate affect were the minor symptoms, which were composed of the major and the minor symptoms of the group with neurotic symptoms and without neurotic symptoms. These symptoms can be seen frequently in the diagnostic criterias and clinical practice and thought to be the result of the major symptoms common in schizophrenia regardless of he presence of neurotic symptoms.

원자력발전소 PSI/ISI 데이터 관리를 위한 지능형 데이터 베이스 프로그램 개발

박은수,박익근,엄병국,박윤원,강석철 韓國非破壞檢査學會 1998 한국비파괴검사학회지 Vol.18 No.5

Windows 95 환경하에서 PSI/ISI 데이터의 효율적 관리를 위한 종합지원시스템의 구축과 다원적평가와 분석이 가능하고, 비파괴검사에 의한 원전기기의 건전성 평가시 규제측면에서 기술적인 지원을 할 수 있는 고리 원전 PSI/ISI 데이터 베이스 구축과 프로그램을 개발하였다. 이 프로그램을 활용하면 현재까지 수행된 고리 원전 PSI/ISI의 수행현황과 지금까지 발견된 결함에 대한 조사분석이 가능하며, 향후 국내 PSI/ISI결과의 자료분석이 가능한 전문가 시스템(expert system)개발에 한단계 접근하게 되었다. 그리고, PSI/ISI에서 발견된 결함에 대한 조사분석 결과를 근거로 결함의 종류, 형태, 처리방법 등에 대한 자세한 분석을 통하여 국내 원전 PSI/ISI 결과의 확률론적 신뢰도 평가, 또는 확률론적 안전성평가를 위한 결함검출확률곡선의 작성과 위험도에 근거한 가동중검사제도의 도입에 필요한 기초 자료를 제공하였다. 더 나아가 지금까지의 자료분석을 바탕으로 보다 경제적이며 신뢰성이 높은 PSI/ISI의 수행으로 원전 압력경계기기의 건전성과 신뢰성 확보 및 수명예측을 위한 기초자료를 제공하였다. For an effective and efficient management of large amounts of preservice/inservice inspection(PSI/ISI) data in nuclear power plants, an intellegent Windows 95-based data management program was developed. This program enables the prompt extraction of previously conducted PSI/ISI conditions and results so that the time-consuming data management, painstaking data processing and analysis in the past are avoided. The program extracts, and the associated remedies. Furthermore, additional inspection data and comments can be easily added or deleted for subsequent PSI/ISI operation. Although the initial version of the program was applied to Kori nuclear power plant, this program can be equally applied to other nuclear power plant. And also this program can be used to offer the fundamental data for application of evaluation data related to fracture mechanics analysis(FMA), probabilistic reliability assessment(PRA) of PSI/ISI results, performance demonstration initiative (PDI) and risk-informed ISI based on probability of detection(POD) information of ultrasonic examination. Besides, the program can be further developed as a unique PSI/ISI data management expert system that can be apart of PSI/ISI data management expert system that can be a part of PSI/ISI Total Support System(TSS) for Korean nuclear power plants.

비트겐슈타인의 대상 개념

박병철 부산 외국어 대학교 1999 外大論叢 Vol.19 No.3

There have beeb many different interpretations of Wittgenstein`s philosophy. The nature of Tractarian objects is one of the much diputed subjects in particular. One of the major reasons for the unsettled disputes is Wittgenstein`s unique philosophical style, which contains hardly any arguments. The nature of Tractarian objects, too, is interepreted in many different ways. One influential reading is initiated by Hido Ishiguro who sees the objects of the Tractatus possess no independent existence. According to this reading, names that designate objects are mere dummy names introduced for the semantical purpose. Unlike this anti-realistic interpretation, David Pears and Jaakko Hintikka have claimed that Wittgenstein`s objects are to be viewed as real entities. They both agree in that Wittgenstein puts forward a kind of logical atomism in the Tractatus. But while Pears thinks Wittgenstein`s logical atomism is different kind from Russell`s, Hintikka sees Wittgenstein develops his theory directly from Russell`s logical atomism. In support of Hintikka`s reading. I argue in this paper that Tractarian objects are variation of Russellian sense-data, i.e., the objects of immediate experience.

A Study on the Performance of Pulse Jet Cleaning in High Temperature Filter

Byong-Ryol Kim,Seung-Chul Park,Byoung-Chul Park,Hyun-Jun Cho,Hyoung-Mo Oh,Tae-Won Hwang,Sang-Woon Shin 한국방사성폐기물학회 2005 방사성폐기물학회지 Vol.3 No.1

To evaluate parameters influencing on the dust removal of the High Temperature Filter(HTF) system, a computer simulation of fluid dynamics inside the system had been performed. The results showed that the optimum pulse jet periods were 50ms and 90ms for the 1000mm and 1500mm long filter elements respectively. Dust removal effect was very excellent under the pulse jet pressure of 3 bar. But the distance between the pulse jet nozzle and the venturi of a filter element had no meaningful effect on the performance with the variation from 5mm to 10mm. Compared to the dispersion mode of pulse jet, the collective mode of pulse jet flow was preferable in maintaining the pressure inside the system stable.

비트겐슈타인과 관상

박병철(Byong-Chul Park) 한국철학회 2008 철학 Vol.0 No.97

비트겐슈타인의 저작에는 ‘관상’이라는 수수께끼 같은 표현이 등장한다. 드물게 사용되었지만, ‘관상’이란 표현은 단순하게 비유인지 아니면 규칙 혹은 의미와 관련된 중요한 함축이 담겨있는지 불분명해 보인다. 이 글에서는 ‘관상’이라는 용어를 통해서 비트겐슈타인이 무엇을 의미했는지에 대한 해명을 시도한다. 그 과정에서 ‘관상’이라는 표현은 대체로 얼굴, 얼굴 표정 혹은 상(체)과 관련지어 나타난다는 점에 주목할 것이다. 그리하여 비트겐슈타인의 관상은 그가 중기 저작 이후에 빈번하게 논의한 상의 인지라는 문제의 특수한 사례에 해당하며, 이른바 그가 말한 얼굴 표정들의 게임이 관상 개념과 밀접하게 관계되어 있음을 보일 것이다. The enigmatic word 'physiognomy' appears in Wittgenstein's writings. It is not clear whether the word shows another occasion of metaphor or the case of significant implication regarding rules or meaning. This essay explores what Wittgenstein means by 'physiognomy'. In the course of discussion, I will pay attention to its appearance with relevant context of where the expressions like 'face', 'facial expressions', or 'aspect' appear. I will show that 'physiognomy' is a special case of the problem of aspect recognition, and that the game of facial expression is closely related to Wittgenstein's use of the word 'physiognomy'.

비트겐슈타인과 철학

박병철(Byong Chul Park) 철학연구회 2000 哲學硏究 Vol.51 No.-

이 논문의 목적은 비트겐슈타인의 철학관을 해명하는 것이다. 비트겐슈타인은 그의 전 ·후기 철학을 통해서 일관되게 철학을 과학과 구분하고 있으며, 그러한 구분을 통해서 철학의 정체성을 확보하려 하고 있다. 『논고』에서 `말할 수 있는 것`의 영역은 곧 과학의 영역이며, 철학은 `말할 수 없는 것`의 영역에 속한다. 비트겐슈타인이 논리적 분석을 통한 언어의 명료화를 통해 유의미한 명제들을 구별해냄으로써 결과적으로 과학적 명제들의 위치를 확보함과 동시에 철학의 정체성을 확보하려 하고 있다. 후기 비트겐슈타인에서도 현상에 대한 순수하고 본질적인 기술보다는 다소간 그 본질이 왜곡되더라도 단순화를 꾀하면서 현상에 대한 설명을 시도하는 과학(물리학)에 대한 논의와 더불어 철학의 기능과 역할을 드러내고 있다. 비트겐슈타인은 그러한 철학의 활동을 문법적 탐구라고 불렀다.
