The purpose of this study is to explore sorts and roles of Afro-American music genres such as jazz, blues, gospel, and swing which were shown in post-structural Afro-American literary works: Toni Morrison's novel Jazz, Alice Walker's novel The Color Purple, and August Wilson's play The Piano Lesson. It has been phenomenal for several important Afro-American writers to create their works in which they invite traditional Afro-American music genres. This has made significant effects to depict a wide range of episodes in their works, which are historically and culturally associated with such music genres. This paper analyzes varied ways in which the writers combine these two artistic fields, which are all Afro-American, and express their authenticity and identity as being blackness.

This study was conducted to investigate the changes in chemical, microbial, sensory characteristics and volatile flavor components of wooung(burdock, Arctium lappa, L) kimchi during fermentation at 15$^{\circ}C$, Three types(A, B, C) of wooung kimchi were prepared. Sample A was prepared with basic ingredients, in the other hand, sample B was prepared with all sorts of ingredients. These samples were mixed after salting the sliced burdock with 4% brine for 30min. Sample C was prepared mixing with all sorts of ingredients after blanching the sliced burdock with 2% vinegar solution. pH decreased slowly until 3 day, and then decreased rapidly for 4~7 days in all samples. Total acidity increased gradually in all samples. The changes of pH and total acidity were the sample C and were the greatest in sample B. The reducing sugar contents decreased slowly until 7 day, and decreased rapidly for 8~14 days in sample A and B, and at 10 day in sample C, respectively. The numbers of lactic acid bacteria and total bacteria of sample B were much greater than those of other sample. In sensory evaluation, sample B exhibited the best scores and sample C showed the worst scores in all characteristics. The major volatile components in wooung kimchi were identified as ethanol, hexanal, 2-hexenal, disulfide dl- 2-prophenyl, zingiberene and $\beta$-sesquiphellandrene. The relative amounts of hexanal, 1-hexanol and ethanol were decreased, while the relative amounts of acetic acid ethyl ester, 3-htdroxy-2-butanone and acetis acid were increased gradually during fermentation.

Government Publications are published to keep records of governmental activities and performances. In a rapidly changing information-oriented society, it is badly required for the operation system of government publications and a library to be effectively managed with government publications for satisfying 'right to know' of people and improving the obligation of government to 'let people know.' Accordingly, the purpose of this paper is to analyze such five research items as the situation of the publication and distribution of, government publications, the operation system of the publications in library, the number of publications regarding secondary information sources for the publications, and the legal deposit of the publications in the National Library, in order to proceed with a subject as to how much the government publication is satisfying 'right to know' of people. The research findings were suggested as follow : 1) Despite the fact that the publication of government publications has been gradually increased every year in numbers and kinds, it is unfortunately pointed out that the publications, distributions and sellings of them were not well organized and systematic. That is, the government publications had not been published more than 1.47% of all publications in number. Moreover, more than the half of the publications were non-periodically or annually published. To make the matter worse, it was not easy to get an access to the publications because of the publications not to be sold. 2) It a n.0, ppears that people could not use the publications efficiently because the library and administrative document office did not pay sufficient attention to public relations for all sorts of government publications. Not only that, there were not enough numbers of publications regarding such secondary information sources as bibliography, index and catalog. A speedy searching capacity for the information gave rise to another serious problem which the government publications could not be effectively used. 3) It is legally stated that all sorts of government publication should be deposited to the National Libraries. However, the law was not properly put into force because of lack of understanding of government agencies about the law.

A computer method is developed for group technology layout and its simulation analysis. The method is composed of three phases: Phase I sorts the parts by its similar production routes and forms part families. Phase II plots the layout by machine cell and evaluates the group layout alternatives by the total process time analysis and the part travel distance evaluation analysis. Phase III also evaluates the alternatives by simulation analysis using SIMAN simulation software. All the computer programs are developed with BASIC except SIMAN simulation.

The purpose of this study was to review the technological deterministic debate that the development of household technology would decrease housework. For the purpose this study made use of all sorts of literature and the interview resources obtained from 86 housewives above 30 years old. It was expected the household capital goods would save housework time and labor. The total time spent in housework and fatigue however seemed not much lessened during the diffusion period. Household capital goods were also expected to enhace the housework satisfaction and increase much housework participation of husband and children; yet neither of them appeared much high during the diffusion period.

The drinking water in the apartment is stored in reservior tank and thereafter supplied each household. In case the drinking water is stored too long or insanitary, tap water might change in quality. This study was carried out to evaluate the physico-chemical and microbiological conditions of 36 samples of tap water of apartments compared to 18 samples of tap water of independence houses in Taegu City from May to October, 1987. Main findings are summarized as follows : PH values were within normal range in all samples. Samples less than 0.2ppm in residual chlorine accounted for 16.7% in the appartment and 5.6% in the independence house. Nitrite nitrogen was detected 2.8% of apartment samples only. Among the total of 54 samples, 11.1% of the apartment and independence samples were over the normal value in standard plate count. Samples more than 1.8 of most probable number(MPN) accounted for 27.8% in the apartment and 33.3% in the independence house. In result of test for residual chlorine, nitrite nitrogen, standard plate count, and MPN, the proportion of the samples revealed inappropriated in respect of drinking water standards. In case of all sorts of tests was 2.7% in apartment and nothing in independence houses, in case of 3 sorts of tests was 2.7% in apartment and 5.6% in independence houses, in case of 2 sorts of tests was 8.3% in apartment and 5.6% in independence houses, and in case of only 1 test was 25.0% in apartment and 22.2% in independence houses. Correlation between residual chlorine and standard plate count, and between standard plate count and MPN were observed. It was found that the more years since construction of apartment were, the worse tap water was in quality.

It may be fully known that Korea is the main producing country of pine tree form the pan-Asian viewpoint of the geographical distribution of the pine tree. Through the study on the reason why the pine tree became a tree of the maximum cover degree in Korea and the observation of natural preservation status of all sorts of trees in the DMZ area for nearly 20 years after the Korean Armistice, it has come to know that almost all of the pine tree were banished. This phenomenon has been resulted by the ecological characteristics of the pine tree itself which has no sprouting power at all, war disasters, deforestation and incendiary fire that have been steadily occurred until now since the time of Armistice.

This paper proposes a CSG-based representation scheme for heterogeneous objects including multi-material objects and Functionally Graded Materials (FGMs). In particular, this scheme focuses on the construction of complicated heterogeneous objects guaranteeing desired material continuities at all the interfaces. In order to create various types of heterogeneous primitives, we first describe methods for specifying material composition functions such as geometry-independent, geometry-dependent functions. Constructive Material Composition (CMC) and corresponding heterogeneous Boolean Operators (e.g. material union, difference, intersection. and partition) are then proposed to illustrate how material continuities are dealt with. Finally, we describe the model hierarchy and data structure for computer representation. Even though the proposed scheme alone is sufficient for modeling all sorts of heterogeneous objects, the proposed scheme adopts a hybrid representation between CSG and decomposition. That is because hybrid representation can avoid the unnecessary growth of binary trees.

The handicapped as a member of a society should possess the same opportunity of a perfect participation in public affairs and an equal opportunity in parity of treatment. All sorts of physical and social barriers surrounding the handicapped who can not having a impairment and disability give a less chance to have a share in their society. Therefore, this discrimination barriers must be phased off not only by handicapped but also by normal social members so as to perfect and free access to movement, all of social institution and social activities. Therefor, this paper provides a basic data which conducts investigation and analysis on the outdoor access environment for the handicapped's easy access to public building or facilities. It would be most import rules to make a decision between improvement rate and object for public building or public facilities.
