본 조사상에 있어서는 외국인 유학생의 한국어 해득의 어려움으로 인한 난점은 물론, 그들을 관할하고 있는 공식기관이 거의 없었으므로 조사대상자 선정 및 질문지 배부와 회수에 있어서 어려운 점이 많았다. 응답태도에 있어서 일부 동양인의 무성의한 태도는 서양인과 눈에 띄게 대조적이었다. 260명의 외국인 유학생을 화교를 제외한 60명 가운데에서 23명을 조사대상자로 하였다. sample size가 소규모적이어서 조사결과를 가지고 통계적 처리를 한다거나, 일반화할 수는 없고, case-study적인 방법으로 조사하였으므로다만 일차적인 조사의 성격을 띠게 되었다.

A unique sialic-acid-binding lectin from giant African snail Achatina fulica(AF) has a T cell mitogenicity. It was also noted that acetone extracts of AF have a anti-HIV effect in vitro. Thirty HIV-infected individuals(HIV+) were treated with AF extract(40% Chunho extract) for average 5. 5 months. Peripheral blood sampling and questionnaire were done every month after take. There was a significant decrease of WBC from 4 months after take. As a result, lymphocyte counts also decreased(P<0.01). However, there was a significant increase of CD4+T cell percentage from 1 month(P<0.01). The mean increase of CD4+T cell count was significant for first one month(39/pl)(P<0.05). Body weight also increased significantly(P<0.05). Over 90% HIV+ ex-pressed symptomatic improvement and wanted to be treated with AF extract continuously after the end of this study. In one HIV+ treated with AF for 19 months, the increases of CD4+T cell percentage and counts over 11 times after AF extract take were mean 67% and 85%, respectively, compared to baseline value. These data strongly suggest that aqueous AF extract has a immune enhancing effect on HN+.

This study was carried out to examine the qualities of soybean curd residue for utilizing as foodstuff. The content of moisture, crude protein, crude fat and ash were 80.98, 3.32, 0.94 and 0.82%, respectively. The major fatty acids were linoleic acid, oleic acid, linolenic acid and stearic acid. The hydrolysate of protein of sobean curd residue was composed chiefly of aspartic acid, glutamic acid, glycine, alanine, arginine and threonine, but the major free amino acids of soybean curd residue were arginine(234.1), ethanolamine (91.6), γ -amino-n-butyric acid(60.2), glutamic acid(55.8), valine(49.8), asparagine(47.3) and Iycine(48.3μ mol/100g).

The purpose of this study was to analyze the relationship between motivation level, job satisfaction along with private security employees job style. For accomplishing this purpose of the study, the 262 subject were selected by the cluster random sampling method from private security employees in 6 private security companies located in Seoul and Kyoung-gi do. The survey questionnaires were used to collect data. The questionnaire for motivation level was developed by Frills and Knox(1972), Quinn and Shephard(1978) and standardized in Korean language by Young-In, Hur(1995) and the job satisfaction was developed by Rizzo(1970) and standardized in Korean language by Yong-Nam, Joo(1993). The statistical methods utilized in this study for analyzing the collected data were reliability analysis, descriptive statistics, Chi-square, t-test, One-way ANOVA, and standard multiple regression analysis. From the analysis of this study, the following conclusions were obtained: Firstly, the motivation level, job satisfaction along with private security employees are partially different by the socio-demographic characteristics. Secondly, the motivation level is not different by the private security employees job style. Thirdly, the job satisfaction is partially different by the private security employees job style. In detail, in job condition along with job style, safe employees are more satisfaction than security employees. Lastly, the motivation along with private security employees influence on the job satisfaction. In detail, the achievement needs, role conflict, and autonomy influence on the job condition and also the role conflict and autonomy influence on the role value.

This study has been carried out to invastigate into the Ostwald Ripering behavior of cementite particles precipitated in 0.45% carbon steel during spheroidizing treatment at a temperature range of from 650℃ to 710℃ after standarding the initial particle size distribution. The results obtained from the experiment are as follows. 1) Average particle size measurements have shown that the slopes of three straight lines obtained from the relation between the log of average particle radius and the log of spheroidizing time for three different temperatures 650℃, 680℃, and 710℃ approaches a value of 1/3 and that the growth of cementite particles occurs by diffusion controlling mechanism. 2) It has been found from the measurements of average radius and the number of particles per unit area that the average value of activation energy is obtained to be 47.1 ㎉/mole, which shows that coarsening of cementite particles is governed by the interdiffusion mechanism of iron and carbon atoms. 3) Cementite particle size distribution curves experimentally measured appears to approach the steady state distribution curve obtained for diffusion controlling mechanism and not to reach it within a spheroidizing time of 640 hours. The shapes of experimentally determined curves are rather broadened compared to that of steady state distribution curve.

金泰圭,閔泳鳳,姜君中 진주산업대학교 1986 論文集 Vol.24 No.-

흐름유체에 열을 가하여 유량변화에 따른 온도변화를 Microcomputer로 계측하는 것을 이용하여 유체의 유량을 측정할수 있는 계측장치를 개발하여 그 성능을 실험적으로 조사한 결科는 다음科 같다. 1. A/D변환기 입력신호 파형의 통科 주파수를 3.88Hz 미만으로 하므로서 관내의 맥동, 외부로부터의 전자파 잡음등의 영향을 소거할 수 있었고, 이를 기준으로 신호처리 회로를 구성하였다. 2. 개발된 시스템의 유량측정은 2cc/sec-133cc/sec까지 가능하였으며, 실험에서 유량 Q와 디지털 값 X와의 관계식은 다음科 같이 나타났다. Q=11.542-0.1805X 3. 본 측정시스템은 저렴한 가격으로 간단하게 제작할 수 있지만 사용목적에 부합되는 유량의 한계에 따라서 측정장치가 보다 개선되어야 할 것으로 생각된다. In order to measure the flow rate in pipe or tube, the microcomputer-based flow measuring system was designed and tested. The system was consisted of 16 channel A/D converter, Apple Ⅱ microcomputer, signal conditioner using OP AMP and flow sensor consisting of a heater and two thermocouples setted in the pipe. The system could be measured the flow rate from 2 cc/sec to 133 cc/sec, but it had some problemes that measured flow rate involved high resolution error and digital value became function of square root of flow rate. Accordingly, the system should be suitable for low flow rate measurement if it exchange the sensor and signal conditioning unit as sensible and linear devices.
