N.B.R. latex was used as the admixture in order to improve the various properties of gypsum plaster which is widely used as the construction material. The influences of N.B.R. latex on the hydration of gypsum plaster were studied. The results obtained are summerized as follows; 1. The water/gypsum plaster ratio is decreased wth increasing amounts of surfactant (P.O.E. Nonyl Phenol Ether) as the additive. 2. It is the pore of large size (${\gg}$7500A) that is mainly decreased with increasing amounts of surfactant. 3. With the small amount of surfactant as the additive, the hydration was slightly retarded, but was gradually recovered with increasing amounts of surfactant, and their heat of liberation after 20 hours were nearly same.

Amino acid composition of Makjang was determined by combined usage of ion exchanged resin and paper chormatography in the following states. a. A fraction soluble in water b. Hydrolysate of the whole Makjang c. Same as a. (p.p.t. formed by tungstic acid or trichloroacetic acid being removed) d. Hydrolysate of c. (T and TCA) By comparing amino acid composition of Makjang with that of its raw material, we found that decomposition of essential amino acids during brewing is slight. From the amino acid composition of a,b,c,d, we discussed the ratio of amino acid liberation during brewing and assumed that Makjang contains peptide-like substances composing of glutamic acid and aspartic acid.

The late Prof. Kyeok Boo Han (1913-2005) was one of the pioneers in the early stages of the establishment of thoracic surgery in Korea. He was in charge of thoracic surgery at Seoul National University Hospital from 1948 to the outbreak of the Korean War in 1950. He presented a thoracic surgical case entitled "Adhesive (constrictive) pericarditis: one surgical case" at the first academic meeting of the Chosun (an old name for Korea) Medical Association, held in 1947. This presentation is considered to be the first thoracic surgical case presented by a Korean surgeon at a domestic medical meeting after the National Liberation from Japanese colonial rule in 1945. In this regard, this study was intended to analyze the content and the meaning of the case, published in a journal in 1948.

This study analyzed the fabrics of Chima, Jeogori of the 20th century. It was based on Kyungwoon Museum relics, newspaper articles and photographs. This research focused on the transition process that has been organized into three stages. The first stage is from the opening of a port to the colonial period in Korea. By this time, the casual wear Hanbok was made with the traditional cotton and woolen textiles in addition to quite a lot of upscale clothing textiles. Stage two is from 1970s to the period after the liberation and Western Costumes represent the time of when the suit was mixed. At the time of the war, due to social and economic difficulties, convenience and practicality were emphasized rather than focusing on aesthetic characteristics. Third period is from the 1980s to the 1990s when the Hanbok was no longer considered a casual wear. Instead, its high quality and elegance redefined it to be a formal wear.

In this study, to look into how much Kim 11-Sung has influenced on the development process of libraries in North Korea after the liberation(l945), the contents related to libraries in Kim 11-Sung's Works were researched and analyzed, the authenticity thereof was verified through some related documents and materials, and finally, based on them, a testimony of a personage who had worked in the educational field in North Korea and his appraisal for this study were reflected.

The first introduction of reformed Korean traditional cloth in was started in the age of civilization and until liberation from imperialism it was made a reformation in faculty from Korean traditional clothing. And by 1980s western style costume took lead but after Asian Game in 1986 and Seoul Olympic in 1988 Korean traditional beauty was added to costume and there were various attempt to produce truly reformed Korean traditional clothing. The present condition of reformed Korean traditional clothing in 1990s are like this : 1) Most of reformed Korean traditional clothing ships could not fractionalize customers. So it needs to subdivide and specialize customer and investment to improvement of design. 2) A large percentage of reformed Korean traditional clothing is ordinary dresses. So it should develop various sorts and color, design and textile and be in harmony with international trend. 3) Most of shops handled a coordinate goods like a bag and shoes. 4) In the investigation customers they wanted various colors, high quality in design , logical price and a periodical sale. So four pieces of the reformed Korean traditional costumes were designed and produced based on the present condition.

This study was conducted to beneficiation of magnesite by dry grinding and air classification. The raw ore was ground in a ball mill and pin mill controlled with grinding time and linear velocity of grinding media and fractionated in an air classifier. Pin mill is more efficient than the ball mill for liberation. As a result, the MgO grade of concentrate was 47.1% with recovery of 51.51% for classified with 3,000rpm of air classifier for ground at 13,000rpm in pin mill.

Several scholars have discussed the relationship between fine art and fashion in meaning and expression. They have established that fashion and fine art are different branches from the same root, the Zeitgeist (time spirit), and that the Zeitgeist is materialized by various expres-sion techniques. The objective of this paper is to discuss how designers' interpretation of the Zeitgeist is expressed in their work, focusing on the 60's American society and designer Rudi Gernreich. The 60's were the period with revolutionary changes both in society itself and clothing. Rudi is the representative of the 60's designers who is called the most avant-garde and American household designer at the same time. Despite his prominent status as an avant-garde designer and social commentator, however, he has not been discussed in depth in the Korean clothing society. The consistent theme of his work was young and free spirit, and women's liberation which reflected the time he lived in. His successful interpretation of the Zeitgeist of the 60's made him establish the American-look, simple and free to move.

Saponin, essential oil, fat oil and alkaloidal fraction were fractionated from the ethanol extract of fanax ginseng. Effect of each fraction of Panax ginseng upon the temperature response induced by reserpine, chlorpromazine and nembutal was investigated in mice, so as to secure some hidden facets of each fraction of Panax ginseng acting upon central nervous system. The authors could arrive at some results, that is: (1) Inhibitory effect of Panax ginseng upon temperature decline induced by nembutal and chlorpromazine and potentiating action upon hyperthermia induced by reserpine reside mainly in saponin fraction and slightly in essential oil fraction. (2) The effect of Ginseng saponin on temperature response in nice seems to be related with the liberation of serotonin and histamine.

The trend towards forming economic blocs coupled with global economic arrangements such as DDA and FTA increase pressure on the liberalization of the agricultural sector. South Korea is taking part in the DDA negotiations. Once the DDA negotiations are implemented, the extent of liberation of the agricultural market is expected to be wider and timing of market opening is sooner than those effects of the UR agricultural agreement. A reduction in tariff rates and the government subsidy will follow, accordingly. However, many analysts in the agricultural sector express deep concern over a negative development in local agricultural market as demonstrated in China where the local market was dominated by imported agricultural products. This study aimed to investigate progress that China made in favor of the agricultural industry, including environment-friendly agricultural policy, and suggest ideas to drive the development of the agricultural industry in a better direction in Korea by comparing the two countries.
