This study was conducted to examine the genetic variations and intraspecific relationships between 9 individuals of Panax ginseng C.A Meyer by using RAPD (Randomly Amplified Polymorphic DNA) analysis. The 34 primers out of 40 random primers were amplified for all tested plants. The 48 (40%) among 244 bands derived from 34 primers shown polymorphism, and the 72 (64%) rest of bands showed similar forms. By regional groups Sangju and Andong samples located in Kyungsang buk-do showed a high similarity. However, Punggi located in Kyungsang buk-do showed higher similarity with Jinan's of Junla buk-do. In this way, it did not show that Panax ginseng from the same area has similarities. In future study we need to more specific molecular phylogenetic analysis such as AFLP technology and gene sequencing with nuclear chloroplast DNA in all samples.

We propose a fuzzy neural network (FNN) theory capable of deciding the quality of a road image prior to extracting lane-related information. The accuracy of lane-related information obtained by image processing depends on the quality of the raw images, which can be classified as good or bad according to how visible the lane marks on the images are. Enhancing the accuracy of the information by an image-processing algorithm is limited due to noise corruption which makes image processing difficult. The FNN, on the other hand, decides whether road images are good or bad with respect to the degree of noise corruption. A cumulative distribution function (CDF), a function of edge histogram, is utilized to extract input parameters from the FNN according to the fact that the shape of the CDF is deeply correlated to the road image quality. A suitability analysis shows that this deep correlation exists between the parameters and the image quality. The input pattern vector of the FNN consists of nine parameters in which eight parameters are from the CDF and one is from the intensity distribution of raw images. Experimental results showed that the proposed FNN system was quite successful. We carried out simulations with real images taken in various lighting and weather conditions, and obtained successful decision-making about $99\%$ of the time.

The content systems of Shinjung Tongguk Yoji Sungnam(신증동국여지승람, A Korean Geography Published in Chosen Dynasty) consist of 26 items and the main subject comprises administration, military and geography, This book does not suggest a simple geography but a comprehensive bibliography as an administrative guide book of a nation or a military operation manual. In particular, this book is made much of as a more valuable material in elevating the quality of the geographic book since it contained a 'Cheyong(제영)' item and reinforced the fields of humanities which could not be found out in other geography. The verses of Cheyong are recorded in the documents in the Chungchong, Kyungsang and Chulla Provinces, and these recorded verses In the tree provinces are more than half of the whole country's. The objects of recitation in the these verses are related to such natural phenomena and historic relics as the mountains, the livers, the wails and the royal tombs.

The purposes of this study are to verify the validity of the conceptual structure of clothing shopping orientation(CSO) developed in the previous research, and to explore the difference of CSO structure between male and female consumer groups. For those purposes, data of 499 male and female consumers were collected. Confirmatory factor analysis, ANOVA, and simultaneous factor analysis were used for data analysis. The results are as follows. First, as a result of confirmatory factor analysis, the validity of conceptual structure of CSO was verified. Second, as a result of ANOVA, male and female showed significantly different CSO at the lower-dimensions level, and as a result of simultaneous factor analysis, male and female showed significantly different relationships between dimensions within the structure. This means that the CSOs of both male and female can be explained by the same CSO structure model, but the specific relationships between CSO dimensions are different by the gender of consumers. Finally, directions for fashion marketing mix concerning the CSO structures of male and female were suggested.

The primary goal of the current study was to examine category solidity of Korean alveolar fricatives in the Busan and Seoul dialects of Korean. Considering the common belief of $/s^h/-/s^*/$ neutralization in Kyungsang speech, plain $/s^h/$ and fortis $/s^*/$ fricatives of Busan speakers were examined against the same fricatives of Seoul speakers. Perceptual distance between Korean $/s^h/$ and $/s^*/$ on the one hand and English /s/ on the other was investigated by use of across-linguistic mapping method. Two experiments of a perceptual mapping task of English /s/ to Korean $/s^h/$ and $/s^*/$ and a $/s^*/$-production task were conducted on users of the Busan and Seoul dialects of Korean. The results from the perception and production experiments suggested that at a micro-level, younger Busan speakers have less solid category stability for Korean $/s^*/$ compared with Seoul speakers, although their production of $/s^h/$ and $/s^*/$ was as highly distinctive from each other as that of Seoul speakers.

The relative toxicity of some of the insecticides which have been used for the control of paddy rice insect pests in Korea was evaluated in the laboratory with the brown planthopper (BPH) Nilaparvata lugens, and a predaceous paddy spider Pirata subpiraticus. In order of the relative toxicity (LD5O value to spider/LD50 value to BPH) were PAP (0.4), MPP(0.1), MEP(1.8), diazinon(2.8), carbofuran(7.5), NAC(11.3), BPMC(17.5), Pyridaphenthion(35.9) and MIPC(65.7). MIPC and Pyridaphenthion were considered as having the desirable selective toxicity for the spider and the BPH.

The purpose of this study is to suggest objective basic data for park management proposal through the quantitative analysis of users' needs and satisfaction for the actual conditions of management in Moaksand provincial park. For this, users' needs and satisfaction for facilities have been analyzed. And user's satisfaction for the actual conditions of management had been analyzed by using the multiple regression. Users want more toilets and sign boards and to replace damaged facilities. Users gave thought to trail and had high pressure to improvement, and many users were uncomfortable by crowding, and had a positive view to restrict use of intensity. Systematic careful concern about trail and rest area should be need and periodic observation to change of facility condition also. According to the multiple regression analysis, the major variable to the satisfaction for the actual condition of facilities management was trail ground condition.

The experiment was carried out to study the variations and geographical distribution of $\beta$-amylase isozyme by isoelectric focusing (IEF) within Korean, Chinese and Japanese soybean land races. In pH 3-10 gel of IEF, the amylase of soybean accessions was separated into low pI group isozymes (TEX>${$Sp_1$}^b$) and high pI group isozymes(${$Sp_1$}^a$). In pH4-6.5 gel, isoelectric points were at 5.07, 5.15, 5.25, 5.40, and 5.94, and h, j, and k bands also were found. The distribution of Sp$_1$$^{a}$ allele (high pI type) was 29.3% in soybean accessions from Korea, 10.1 % in those from China, and 6.9% in Japanese accessions. The percentage of ${$Sp_1$}^a$) allele was the highest in soybean accessions from Kyungsang province (35 %) in Korea, then central China (32 %) in China, and Honshu (10%) in Japan.

This study identifies the effects of the perceived risk by adolescents on fashion brand conformity for peer groups. Perceived risk, self-esteem, and gender were adopted as variables in order to analyze conformable fashion brand behavior with peer group consideration. A quantitative survey used 672 questionnaires from male and female students between the ages of 14 and 18. The data were analyzed using factor analysis and regression analysis. The results are as follows. First, the dimensions of the brand conformity and perceived risk were revealed. The brand conformity dimensions were normative, informational, and identificational conformity. The perceived risk dimensions were socio-psychological, economic, exchange-refund, performance, management, and fashion risks. Second, fashion (+) and performance (-) risk significantly affected three types of brand conformity. In addition, socio-psychological and economic risk positively affected informational brand conformity. Third, there were more factors of perceived risk that affected brand conformity in the highly self-esteemed group and in the female adolescent group.
