Most of our college students in the department of electricity are from technical high school. Thinking that a lot of those high school students are going to try out for our college, we have come up to the idea to have stable student resources and to keep the resources that we should have researched on this matter. As first solution, considering scholastic ability for students, our college should help them to have easier understandings on their major subject studies. To let them have better condition of studying, we have analyzed 6th and 7th high school curriculum for electric text and studied how much influence 7th the curriculums have on major subject studies. Also we have looked through high school mathematics and basic electric texts under 7th the curriculums. After examining these analysis, we have had some suggestions about the ways to provide easier understandings and reorganized contents in a major basic text of college.

Today, a broad comprehension of society for the disabled persons has been increased with the industrial development and sustained economic growth. But unequal elements of social environment have bring about many constraints for the daily living of disabled, and turn out a major causes that can not so much as guarantee their own legal rights. The establishment of facilities which guarantee the free approach and movement of disabled persons in the campus is the first way that minimizes the distinct elements which restrict educational opportunity with obstacles, and acts a part as improvement for the quality of disabled with their positive social participation. In this study, we want to propose the improved schemes that minimize the physical obstacles of educational facilities through the analysis of problems and situations which are obtained from the investigation of the actual conditions for the facilities of disabled in the yeungnam college of science and technology. And we wish to use the results of this paper as a basic data for the future construction plan of campus.

배추의 鹽漬處理에 따른 脫水現象과 食鹽浸透

This study was carried out to investigate the weight loss and the NaCl gain of chinese cabbage samples during pickling in brine under different conditions including various salinities, brine temperature and leaf shape with relation to kimchi making. When the whole leaves of chinese cabbage samples were used for pickling, their weight loss ratio and NaCl gain increased significantly through all the period of pickling as brine salinity did. Drastic dehydration of pickled leaves occurred especially within 2 hours after brining, thereafter their rate of dehydration decreased greatly and their weight loss ratios in brine salinity 2, 5, 10, 15, 20% were 5.72, 14.81, 15.61, 17.34, 24.10% respectively 12 hours after brining. NaCl gain in pickled cabbage samples was increased greatly in the early stage of brining but it had the tendency to increase still thereafter. The content of NaCl of all the samples pickled at brine salinity 2, 5, 10% did, not reach 3% even 12 hours after brining while that of samples pickled at brine salinity 15,20% reached 3% in the brining time, 6. 7, 3. 8 hours respectively. As the temperature of brine rose, dehydration of pickled cabbage samples did not increase except at the early stage of brining but their NaCl gain increased significantly. In case of pickling of sliced leaves, weight loss ratio increased greatly, reaching twice as much as that of whole leaves at the same brining conditions 12 hours after brining but NaCl gain had no significant difference between them. On the other hand, it was shown that the very high correlations between NaCl gain and weight loss ratio in chinese cabbage samples pickled by the same brining conditions existed.

몇 種의 Bis-(iminodiacetic acid)와 構造的 非對稱의 p-Amino-benzenesulfonamide와의 縮合重合에 關한 硏究

姜聖求,李萬熙 영남이공대학 1987 論文集 Vol.16 No.-

Poly (2.6-piperazinediones) were synthesized from several kinds of his (iminodiacetie acids) with structurally unsymmetrical p-arninobenzenesulfonamide. For determining the reactivity, the author calculated forontier electron density of p-aminobenzenesulfonamide by simple Hu''ckel method. Nitrogen atom of amino group attached directly to benzene nucleus in p-aminobenzenesulfonamide was found to be 23 times greater than one of amino group attached to sulfonyl group in nucleophilicity. Consquently, the former nitrogen atom prior reacted with acids and then the latter nitrogen atom. Solution polymerization was carried out in DMSO and melt polymerization was by heating the salts of acid and diamine in reactor. The yield of polymers obtained from melt polymerization has been found to be lower than that of solution polymerization. That is, the yield of the fomer was 30% and that of the latter was more than 70%. The auther found that that the structually unsymmetric was soluble in such polar solvents as p-cresol, formic acid, and dimethyl sulfoxide. while other polymers having structurally symmetric sulfonyl group were not soluble. The values of intrinsic viscosity obtained from the plot of redued viscosity versus concentration were in the range of 0.12 to 0.69. Since polymers melt in the range of 245 to 369℃, the thermal stability of these polmers was found to be greater than other polymers with the symmetric sulfonyl group.

디젤기관용 screw swirl 노즐에 관한 연구

金宇燮 영남이공대학 1987 論文集 Vol.16 No.-

Experimental investigation has been made of screw swirl nozzle for diesel engine. Compared with single screw swirl nozzle, triple screw swirl nozzle can produce finer spray pattern. But the atomizing quality under low injection pressure was poor at the beginning stage of injection. To improve of the defect, the swirl chamber of the single screw swirl nozzle must be made as small as possible and the needle lift be lowered.

김주남 영남이공대학 2000 論文集 Vol.29 No.-

To determine the effect of diet on Ca Intake, this study was conducted with 67 female students in Yeungnam College of Science & Technology, Taegu. The subjects were 18 on a diet as a diet group(DG) and 49 not on a diet as a non-diet group(NDG). The results are summarized as follows. 1) The mean age of the students was 19 years old, 78.2% of the students lived with their parents. The average stress extent of the students was 67.4%, and the proportion of those who drink once to three times a month accounted for 402% which was the highest. 2) There was no significant difference in their heights but the weight of DG weight was significantly higher than NDG's(p<0.001). There was also a significant difference in the Body Mass Index(MBI) between DG and NDG(p<0.001). Body Mass Index of DG was normal but it was under the range of low weight in NDG. In a desired weight there was a significant difference between IX; and NDG(p<0.05). DG desired 50.4㎏ whereas NDG did 47.4㎏. 3) In both groups, the average score of eating habits and food intake frequency score were no significant difference. 4) The results of examination of dietary intake by 24-hour retrospection method showed that the total amounts of daily caloric intake were 1263.8㎉ in DG and 1773.9㎉ in NDG and accordingly there was no significant difference. However, %RDA of NDG accounted for 85.3% which was higher than DG's(62.2%). Although there was no statistical significance, NDG tended to have more daily intakes of carbohydrate and fat than DG, but protein was significantly higher than DG. In the calcium intake, there was no significance in the total amount of daily calcium intake. 5) In both groups, major contributors of calcium was milk, yoghurt, sesame etc.

Life prediction or residual life of structures or machines are one of the most strongly world loide needed problems as requirement in the stage of slowly developing economy which comes after rapidly and highly developing stage. For the purpose of life, Prediction fatigue test was conducted under a stress level, and for this stress level, 24 specim?ns are used. The properties of the crack growth parameter m and c in the fatigue crack growth law of da/dN=C(△K)^(m), and the relation ship between m and C, and the distribution pattern of fatigue crack growth and failure lives can be obtained by experimental results.

The spatial performance in modern architecture should be the act that could be more functional and comfort space for cultural life. Therefore in this paper focused on the creation of architecutural form, the concepts of architectural design vocabulaies are re-defined by the unification of the fundamental theory of form and the classification of design vocabularies. This is for the space not inhuman but human.
