密度差에 따른 毛編織物의 收縮率에 관한 硏究 : It's Dependence Upon Fabric Structure and Tightness
崔聖姬 이화여자대학교 가정대학 의류직물학과 1971 의류직물연구 Vol.- No.1
This study was carried out on the washing of Fabrics knitted from wool and wool/ manmade fibre blends. Two of them were all wool and the rest were wool/ man-made fibre blends. Each of them- had two kinds of knit structure, plain, and rib stitch, and all the structures had three level of compactness. The washing was operated by the wash wheel method. In order to find out the dimensional changes of the fabrics during washing, it was measured the area shrinkage of all the specimen which was marked with indiable color thread. Besides, the tests of wear, thickness, strength and air permeability was carried to find out the relation of structure compactness and other properties. There were three significant interaction between the factors for the data. These showed that the shrinkage rates of, the fabrics was decreased, by increasing cover, factor the shrinkage rates between plain and rib stitch were very close together when cover factor was constant, and thickness and strength of the fabrics were increased by increasing cover factor, on the other hand wear and air permeability of the fabrics were decreased by increasing cover factor.

고도의 정보 산업 시대를 맞이하여 소프트웨어 산업의 발전을 위한 방안으로 컴퓨터 프로그램 보호법으로부터 법적 보호를 받지 못하는 오브젝트 프로그램과 프로그램 이외의 결과물 및 데이터베이스에 대한 법적 보호 방안에 대하여 연구하며, 또한 프로그램 등록 제도의 활성화를 위한 보완 방안에 대해서도 연구한다. We study the lawful protection of the object programs, outputs except the programs, and the database that are not protected by the law for the expansion of the software industry in the age of high technological information industry. We also study the plan for improving the program registration system.

The objective of this study was to investigate the physicochemical characteristics of binary and ternary oil systems. Materials used in this experiment were four edible oils i. e. sesame, soybean, red-pepper seed and Sancho (Zanthoxylum schinifolium) seed oils. The physicochemical properties of mixed oils, as well as the inductive period of oxidation, were measured. The results obtained are as follows : 1. The optimum mixing ratios of sesame oil with each of soybean, red-pepper seed and Sancho seed oils, which still maintained a characteristic sesame oil flavor, were 1 : 3,1 : 0.5 and 1 : 0.5, respectively. 2. Sesame, soybean and red-pepper seed oils showed low acid and peroxide values. In contrast, however, Sancho seed oil showed the very high values, and acid, peroxide and TBA values were 17. 4, 28.6 and 1.8, respectively, Among the oils, soybean oil gave the longest induction period of oxidation and Sancho seed oils the shortest, and the induction period was increased in order of Sanch seed, red-pepper seed, sesame and soybean oils. 3. Binary oil system such as a mixed oil of seasame oil and each of soybean and red-pepper seed oils did not show any significant change in acid, peroxide and TBA values, but a mixed oil of sesame oil and Sancho seed oils gave a drastic change in acid (7.2), peroxide (12.3), and TBA (0.2) values. All the binary oil systems extended their induction periods of oxidation. 4. In ternary oil system, a mixed oil of sesame, soybean and red-pepper sees oils did not show any significant change in acid and peroxide values. In contrast, however, mixed oils of sesame, red -pepper seed and Sancho seed oils in the ratios of 1 : 1 : 1 and 4.5, 8.9 and 0.13 in the ratio of 1 : 0.25 : 0.25, respectively. All the ternary oil systems also extended the induction period of oxidation.

이 논문에서는 Information-based complexity 분야의 문제에서 solution을 구했을 때 그 solution에 포함되어 있는 오차(Error)의 성질에 대해 연구한다. 주어진 문제의 setting에 따라 오차가 다르게 정의되며 이 때 이 오차의 한계와 이 문제의 complexity에 대해 연구한다. In this paper, we study the properties of the errors in the approximate solutions for the Information-based complexity problems. The errors are defined differently according to the given problem settings. We study the error bounds and the complexities for the problems in each settings.

Throughout history tea has been an extremely important facet of Korean culture. During the time of the Yi Dynasty, however, tea began to disappear in everyday life and was preserved only in Buddhist temples in the mountains. However, traditional tea culture is now being revived and is slowly finding its place in Korean culture. This study was carried out in order to confirm characterization of aroma of green tea made from Dasolsa well-known with tea in Korea. The concentrated extract was analyzed and identified by GC and GC-MS. The main aroma components of these teas were nerolidol(9.31%), linalool(8.10%), cis-jasmone(4.13%), geraniol(1.72%), cis-2-heptenal(1.68%), α-terpineol(1.52%) and β-ionone(1.38%).

The essential oil fraction of flowers of Chrysanthemum boreale Makino was analyzed. The essential oil fraction of it was collected by simultaneous distillation and extraction method and was analyzed and identified by GC-MS. Main components in the essential oil fraction of flowers of Chrysanthemum boreale Makino were terpene hydrocarbones, such as camphene, β-pinene, α-farnesenc, α-phellandrene and ρ-cymene etc and terpene alcohols, such as 2,10-boranediol, terpene-4-ol, α-terpineol and trans-(+)-carveol etc.
