The present study was to examine the relationship between psychiatric inpatients' occuputions and their anxiety level. The sampling subjects were randomly selected by 3 stage probability proportional culster extraction method among psychiatric who were admitted to the psychiatric clinics and hospitals nationwide. Four hundred and twenty eight subjects including 249 males and 179 females were undergone by questionnaire survey while measurement of anxiety was done by using Zung's self-rating anxiety scale. Collected data were processed by IBM PC AT computer using SPSS program and statistically analyzed by chi-square test and analysis of variance. 1) It was revealed that these psychiatric inpatients showed relatively higher rates of the unemployed (34.6%), single(43.2%), and divorce(5.1%). 2) Patients with higher classes of occupation such as administrative, managerial or clerical workers showed higher rate of divorce. 3) In the occupational distribution of psychiatric disorders, psychotic disorders were more prevalent among high or low occupational classes, neurotic disorders more prevalent among middle occupational classes, while psychoactive substance use disorder more prevalent among farmers and sales workers. 4) Overall the mean anxiety score of the whole subjects is 39.28 ±14.67. The mean anxiety score (39.71±14.89) of the pschiatric inpatients with job is higher than that (36.59±14.20) of the unemployed. 5) In the anxiety tendency according to occupational classification, the unemployed showed less anxiety compared with the employed. Patients with middle occupational classes such as fishing workers and sales workers showed higher levels of the cardiovascular, musculoskeletal, respiratory and skin system anxiety, while patients with higher or lower occupational classes showed lower anxiety. In the relationship between occupational classes and level of anxiety, it showed profiles of inverted V curve. 6) The lower occupational classes such as sales workers showed higher anxiety level, while the higher occupational classes such as clerical workers showed lowest one. Particularly the fishing group exposed in the higher stress situation showed the highest level of anxiety.

Since the ceramic/metal joints at high temperature, the residual stress will develops during when it is cooled from bonding temperature due to remarkable difference of thermal expansion coefficient betwen ceramic and metal. Moreover, the edge of jointed interface makes singular stress field in the ceramic/metal joints and this singular stress field much influences on the strength of joints. In this study, the influence of residual stress, mechnical load and repeat thermal cycle were estimated in the ceramic/metal joints. According to this influence, the change of singular stress field was analyzed. The results are as follow : 1) Strength of joints was evaluated by the stress singularity index λ and the intensity K of singular stress field. 2) the stress singularity index λ and the intensity K of singular stress field also increase as adding temperature of thermal cycle and its number of cycle. 3) In the case of mechanical load, the influence of residual stress reduces since the difference(Δλ) of stress singular index between existence and inexistence of residual stress decreases in proportion to the increasing of tensile load.

A METHOD ON AUTOMATIC TRANSLATION OF SEQUENTIAL PROGRAMS INTO DATA FLOW PROGRAMS

기존의 Von Neumann Model 방식의 Sequential Program을 Speed-up 시키는 방법들이 연구되어왔다. 이는 Von Neumann Model방식의 Uni-processor를 사용해서 program을 execution시키는 speed-up에 한계가 있다는 것이다. 그래서 sequential program을 speed-up execution 시키기 위해서 multi-processor를 도입하였고 multi-processor에서는 program을 execution 시키는데 parallel processing을 해야만 execution time을 speed-up시킬 수 있다. 이런 parallel processing에 근거를 두고 개발 된 system 이 data flow system이다. 그러나 기존의 Von Neumann 방식의 sequential program은 data flow system에서 직접 execution 시킬 수 없다. 그러므로 기존의 sequential program을 data flow execution 시키기 위한 automatic translation 방법을 도입하였다. 이를 위하여 본 paper에서는 dependency testing algorithm 과 automatic translation algorithm을 도입하였고, 이를 이용하여 sequential program을 data flow program으로 automatic 하게 translation하였다.

FRONT SUSPENSION의 LOWER ARM에 대한 최적설계

박영철,윤두표,허선철,조용배 동아대학교 공과대학부설 생산기술연구소 1997 生産技術硏究所硏究論文集 Vol.2 No.1

LOWER ARM which jointed Independent Front Suspension is resulted in stress sidtribution analysis by using Finite Element Method. These datas represented in the condition of 8 loads and 3-type-section(I, H and H+I) type. On the basis of it, it is optimized shape and dimension fo LOWER ARM. The optimized performance shows that the H type of 3 types has an available strength and H´ section, which proved by H type, finds safety factor and yield strength in each case of load condition.

An experimental investigation has been performed to determine optimal conditions for preparing the thermoluminescent CaSO_(4):Dy pellets which have been widely used as personal radiation dosimeter material. Our investigation has shown that an optimal weight concentration of the dopant Dy in the bulk CaS0_(4):Dy is 0.1 mol%. and an optimal temperature of adding Dy in the preparing process is 320℃. An optimal time and temperature for sintering the CaSO_(4):Dy crystal produced from the chemical process are found to be 2 hours and 800℃. respectively. The maximum thermoluminescent sensitivity was observed when the CaSO_(4):Dy crystal was pulverized to grain sizes of 63 - 200 m in diameter before being fabricated into pellets. The commercial Teflon was selected as an adhesive for the fabrication of the CaSO_(4):Dy pellets with an optimal mixing ratio of the Teflon and CaSO_(4):Dy being 70 to 30 in weight.

Gastric candidiasis is an uncommon disorder. It is an opportunistic pathogen in immune compromised individuals, alcoholics, persons treated with broad-spectrum antibiotics, immunosuppressive and chemotherapeutic agents. Besides, the use of drugs that reduce the gastric acid production may be a cause of gastric candidiasis. We experienced a case of gastric candidiasis following advanced gastric adenocarcinoma. A 85-year-old woman was admitted to our hospital because of epigastric soreness. Endoscopic findings revealed a large ulcero-infiltrating mass with yellow exudate at cardia of the stomach, which suggested an advanced gastric cancer. Endoscopic biopsy revealed spores and pseudohyphae infiltrating through the ulcerated stomach wall, diffuse infiltration of tumor cells and abortive tumor glands. After treatment with fluconazole 100 mg daily for 21 days, no evidence of the gastric candidiasis was seen on endoscopic biopsy and pathologic findings. The case is herein reported of gastric candidiasis following advanced gastric adenocarcinoma along with a review of corresponding literature.

There has been a sizable growth in the use of rich media over the World Wide Web(WWW) as more individuals and institutions realize rich-media's potential in a broad range of applications, including electronic commerce, education and training, news, etc. Internet and WWW technologies provide the information of the web. Libraries are systems that carry out interactions among information and knowledge seekers. Library become more and more important for the provision of data. Total information system for books management exist in many forms. We present total information system for books management which is applied to several different sources, e.g., administrator security login, statistics about the present state of lending, printing management, and convenient GUI(Graphic User Interface) environment.

중간가공열처리를 거친 8090 Al-Li 합금의 Delamination과 저온기계적성질

맹선재,박기두 漢陽大學校 工學技術硏究所 1996 工學技術論文集 Vol.5 No.1

Low temperature tensile properties and charpy V-notch impact properties of 8090 Al-Li Alloy have been studied after thermomechanical treatment. The test samples were machined in the L-T direction. By decreasing the test temperature, both the strenghth and elongation, and the impact energy have been increased. The cracks have propagated along the grain boundaries in the longitudinal direction. Delaminations in the tested samples have been increased by decreasing the test temperature. The increase of total delamination length in a sample corresponded to the increased fracture toughness value, and the impact energies. Cold working after solution treatment contributed decreasing the delamination and impact energy, when compared with the non-cold worked case.
