The objectives of this study are to identify flood disasters resulted from heavy rainstorm including earth and stone-debris avalanches and also to develope the scientific data to be needed for establishing the landslide-related disaster prevention countermeasures. For this study, 5 Gun (district) regions including Booyeo, Seochun, Gongju, Boryung, and Chungyang in Chungchongnam-do of the central part of Korea, in which severe landslide damages have been triggered during 3 days from July 21 to July 23, 1987, were investigated. Mostly, landslides having death of human lives triggered from 6 a.m, to 8 a,m. on July 22, and the principal factor was proved to be the continuous heavy rain ; the continuous rainfall of internal region for 3 days measured about 300-673 mm. The structural measures for slope failure prevention countermeasures at the hollow part of upper hillslope should be required. Natural drainage network on slopes should not be disturbed in case of land use alteration, such as a chestnut planting work on hillslopes behind the houses particularly. There are so many problems in recognition of landslide disaster prevention countermeasures including evacuation exercises. More actual education of countermeasures for control of flood and landslide should be put to practice through "civil defense education" and "inhabitants' meeting." In this context, existing Erosion Control Stations of 13 regions established in each Province should not be reduced. The designation criterion and surveying processes of "Landslide Prone Site" published by Forest Administration should also be improved scientifically.

The overall objectives of this study were to examine the potential of sturgeon as an intermediate moisture food (IMF) by measurement of nutritional components, such as minerals, fatty acids, amino acids, and water activity. Chemical compositions were as follows:moisture 73.2%, crude protein 19.9%, crude lipid 5.7%, ash 1.1%, and carbohydrate 0.1%. Minerals were K 317.70, P 259.88, and Mg 29.78 mg/100 g. Fatty acids detected were oleic acid (40.46% of total), palmitic acid (23.27%), and linoleic acid (15.35%). In addition, sturgeon was very rich in glutamic acid (1,189.71 mg/100 g) and deficient in serine (55.12 mg/100 g). Moisture content and water activity of sturgeon dried at $40^{\circ}C$ after soaking in different concentrationsof sugar and salt solutions were 15.12-16.24% and 0.68-0.79, respectively. Sensory evaluation of sturgeon soaked in different concentrations of sugar and salt solutions indicated that sturgeon soaked in 3.0% (w/v) sugar and salt solution scored highest.

The classification scheme of records indicates a table that intends to express organic relations between records by organizing records and enabling internal order. Although the principles of organic classification have remained in traditional records management environment, they have been changed to "function and business" in the modern times. Therefore, Korea introduced a business reference model (BRM) based on function and business from 2008 and subsequently implemented its operation. However, it has been pointed out that the roles of the classification scheme of records have not been played because the analysis of "Danwigwaje," which belongs to the lowest level of business reference models, is poor. According to this indication, the Gangbuk District of Seoul Special City established a functional classification scheme by executing a business process analysis of "Danwigwaje." First, the record manager carried out analyses on the principles of "Danwigwaje," small function, and "Danwigwaje." Then, the functional classification scheme of "Danwigwaje" was modified by looking into the opinion inquiry process of the treatment department and performing a test operation. Through the case of the Gangbuk District in Seoul Special City, analytical procedures and methods of "Danwigwaje," as well as implications according to the establishment of a functional classification scheme of basic local governments, were arranged in a written format.

This paper tried an approach of oral literature as the research subject of Soeburi song in Ulsan. First, UlsanSoeburi song is meaningful as materials collected in Ulsan such as Hansil, Dodoekgol, Dudong and Byeongueong. In addition, it is related to regional identity as song native to Ulsan, which has prototype and archetype. And it shows that Ulsan is the city as well as hometown of Soeburi(meaning ' iron manufacture'). The characteristics of lyrics are different between Hansil Soeburi song and Dodeokgol Soeburi song. Jeiman Choi is considered as a good oral literature poet, because he is a performer who is faithful in official structural principal and in original lyrics(archetype) of Soeburi song. Therefore, SoeburiBulmei song of Jeiman Choi signifies aesthetic meaning, having lyrics which make to feel labor's purity and sacred and melody which overcomes labor's difficulty through united action. On the other hand, SoeburiBulmei song of Dalo Kim in Doseokgol shows that he is a extemporaneous performer even though he performs based on official structural principal. In this paper, transmission and changes of UlsanSoeburi song are divided into basic type, frequent shift type and overall type. 'Basic type' originates from Jeiman Choi's Soeburi song in Hansil. 'Frequent shift type' was created by combining SoeburiBulmei song of Dalo Kim in Doseokgol and SoeburiGeumjul song in Ulsan. 'Overall type' is current Soeburi song, which was created by adding Bulmei song for lulling a baby in Byeongueong near Dalcheon region and Seoknyanggan(smithy) Bulmei song. UlsanSoeburi song is being passed down continuously, strengthening the identity as a representative folk song in Ulsan through endless process of transmission and changes.

Library is a social institution that satisfies the intellectual needs of the community and provides information, cultural enjoyment, and continuing education to the community. However, it is true that a library may face with difficulties in satisfying the diverse and advanced needs of its users and performing its newly acquired roles because of the limited financial resources of state and local governments. Therefore, this study proposed the introduction of corporate donations as one of the options for library funding, both for expansion of critical library infrastructure and for the internal stability of library operations. To this end, this study determined corporate donation goals, donation targets, campaign donations, the number of libraries being built and renovated, and the effects on libraries that obtained corporate donations by investigating and analyzing known corporate donation cases. The results of this study could be used by libraries hoping to attract corporate donations.

The thesis covers the trend of research on bio-based polyurethane which is made from polyols derived mainly from plant oils and isocyanates. Castor oil is a triglyceride of ricinoleic acid containing hydroxyl group. Hydroxylation is done on the unsaturated bonds of the oils by the reactions of epoxidation/ring opening, hydroformylation/hydrogenation, ozonolysis/hydrogenation, and thiol-ene reaction. Polyols from hyperbranch, primary alcohol, polysaccharide have been studied to control the reactivity of the polyol and morphology of the microdomains. Besides, researches cover biodegradable polylactic acid polyol for medical use, fatty acid dimer polyol for the prevention of hydrolysis, and polyol with ionic group for water-borne polyurethane. Bio-based polyurethanes are being used in flexible and rigid foams, coatings, sealants, and elastomers.

A weed population has been mainly analyzed through vegetative analysis method in ecology. However, this method is difficult to understand a detailed feature of weed dominance in terms of region and a particular weed species. Since GIS(Geographic Information System) tool has been introduced, this constraint was able to be solved. GIS analysis for the nationwide weed survey data in 1981 revealed that most predominant weed was Monochoria vaginalis and this species predominated mostly in a western part of Chungnam, a part of Kyunggi, a northern and southern part of Kyungbuk province of Korea. Eleocharis kuroguwai which was the most predominant weed species in 1992 was occurred at southern part of Kyunggi, central and western parts of Chungnam, and southern western part of Chumnam at the GIS analysis. GIS analysis was proven to give much more detailed information than vegetative analysis of weed population and this means that a data analysis by GIS would be used for operating a high effective control strategy against target weed species and site.

This study was conducted to investigate the effect of superheated steam (SHS) on the improvement of quality during the manufacturing process of Samgyetang products. SHS cooking showed the increase in moisture content and the decrease in protein. In terms of chromaticity, the value of L was significantly higher in the $2^{nd}$ SHS cooking compared to conventional cooking. As for texture, the hardness decreased in Samgyetang with SHS cooking than conventional cooking. According to the results of the safety experiment with a 14-day refrigerations storage the total number of bacteria was lower in the SHS cooking compared to conventional cooking. The TBA value increased to 0.59-5.70 mg MD/kg after 15 days; VBN values were also 0.70-4.54 mg% in SHS cooking indicating a slight decomposition. Overall, it was found that SHS cooking and HHP were more preferred and also had an effect of reducing microorganisms, which were improvements in product quality and sanitation.

Volatile flavor components from various edible portions of Capsella bursa-pastoris were collected by simultaneous steam distillation-extraction (SDE) method using diethyl ether as solvent. Essential oils were analyzed by gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC-MS). Thirty four volatile flavor components, including 12 hydrocarbons, 2 aldehydes, 2 ketones, 5 alcohols, 1 ester, 10 acids and 2 miscellaneous ones were confirmed in whole samples. Thirty one components, including 11 hydrocarbons, 5 aldehydes, 4 ketones, 5 alcohols, 1 esters and 5 miscellaneous ones were confirmed in leaves. Twenty four components, including 5 hydrocarbons, 1 aldehyde, 2 ketones, 6 alcohols, 2 esters, 1 acid and 7 miscellaneous ones were confirmed in roots. The kinds and amounts of volatile flavor components revealed different patterns depending upon various edible portions. Relatively greater numbers of volatile flavor components were identified in leaves compared with roots of these wild plants. The characteristic aroma of Capsella bursa-pastoris appeared to be due to combination of C6 alcohol and acids, terpene alcohol and sulfur containing compounds.
