In order to identify the factors responsible for the recent drastic increase of imported apparel in Korea, an attempt was made to determine the variables influencing the purchasing behavior of imported and domestic apparel and forecast the purchasing intention with the use of Fishbein & Ajzen's behavioral intention model including both attitude and subjective norm. Based on literature review, the empirical study was conducted using the questionnaire for 900 college women and high school girls living in Seoul. Descriptive statistics, t-test, paired-t test, multiple regression analysis, and correlation analysis were made of 771 returned questionnaires using SAS program. The results were as follows : First, the results of assessing both their attitudes toward imported and domestic apparel and their subjective norms were shown to be different. Second, there was a difference in the attributes that had an effect on their attention to buy imported and domestic apparel. Third, those respondents having a preference for imported apparel were most highly influenced by color and price. While those respondents showing a preference for domestic apparel were most highly influenced by materials and comfortableness. Fourth, the validity of the prediction value of their buying intention was confirmed as it was shown to be more than coreelation coefficien r=0.65. In conclusion, 1) it was proved that both attitude and subjective norm were the important variables that could predict the consumer's purchasing intention, 2) since competitiveness in color and materials and brand influencing the consumer's purchase of and preference for domestic apparel relatively lagged behind in comparison with that of imported apparel, the domestic apparel business enterprise will have to make a greater effort to develop differentiated color, material and prestigious brand so as to enhance competitiveness with imported apparel.

Various sizes of dolerite sills occur in the Mungyong area, one of well-exposed areas in Okchon belt. All of previous geochemical studies concluded that chemical variations of basic rocks, so-called Sangnae-ri amphibolite, result from the fractional crystallization. The second sill, which is a well differentiated one in the Sangnae-ri area, displays systematic compositional variation associated with gradual change of grain size in vertical sections. In order to clarify the chemical variation in the sill, whether chemical composition of each part of the sill is appropriately derived from the original liquid (represented by the average composition) by addition or subtraction of initial phenocystic minerals are tested(Iwamori program, 1989). According to the calculation, it is shown that major vertical chemical variation of the sill resulted from the accumulation of phenocrysts(olivine, clinopyrxoene, plagioclase, titanomagnetite) which already existed at the time of emplacement or formed just after the emplacement.

Twenty isolates of Didymella bryoniae were isolated from infected cucurbit plants in various growing areas of southern Korea in 2001 and 2002. Random Amplified Polymorphic DNA (RAPD) group [RG] I of D. bryoniae was more virulent than RG IV to watermelon. Virulence of the RG I isolate was strong to moderate to cucumber, whereas that of the RG IV varied from strong, moderate to weak. Two hundred seventy-three amplified fragments were produced with 40 primers, and were analyzed by a cluster analysis using UPGMA method with an arithmetic average program of NTSYSPC. At the distance level of 0.7, two major genomic DNA RAPD groups were differentiated among 20 isolates. The RG I included 7 isolates from watermelon and one isolate from melon, whereas the RG IV included 12 isolates from squash, cucumber, watermelon and melon. Amplification of internal transcribed spacer (ITS) region and small subunit rRNA region from the 20 isolates yielded respectively a single fragment. Restriction pattern with 12 restriction enzymes was identical for all isolates tested, suggesting that variation in the ITS and small subunit within the D. bryoniae were low. Amplification of the genomic DNAs of the tested isolates with the sequence characterized amplified regions (SCAR) primer RG IF-RG IR specific for RG I group resulted in a single band of 650bp fragment for 8 isolates out of the 20 isolates. Therefore, these 8 isolates could be assigned into RG I. The same experiments done with RG IIF-RG IIR resulted in no amplified PCR product for the 20 isolates tested. An about 1.4 kb-fragment amplified from the RG IV isolates was specifically hybridized with PCR fragments amplified from genomic DNAs of the RG IV isolates only, suggesting that this PCR product could be used for discriminating the RG IV isolates from the RG I isolates as well other fungal species.

This study was designed to identify the relation between the Perceived Social Support and the Self-care Agency of high school students in a rural area. The subjects for this study were 250 students living in Chonnam province: among first grade, second grade and third grade students were 98, 89 and 63 respectively. The data were collected during the period from April 2 to 4, 2001. The instruments used in this study were the Generally Perceived Social Support Scale developed by Park, J. W.(1985) and Self-Care Agency Questionnarie developed by Deneys(1981). The data were analyzed by descriptive statistic, t-test, ANOVA, and Pearson's correlation using the SAS PC+ Program. The results were as follows: 1. The mean score of the Perceived Social Support was 3.19. 2. The mean score of the Self-care Agency was 2.65. 3. There was a significant differences in school year(F=3.11, p=.046), educational level of the father(F=3.41, p=.035) that of the mother(F=4.07, p=.019), and economic status(F=8.99, p=.000), school performance(F=16.37, p=.000) from Perceived Social Support between general characteristics. 4. There was a significant differences in economic status(F=4.55, p=.004), school performance(F=6.72, p=.002) from self care agency between general characteristics. 5. The relation between the score of the Perceived Social Support and Self-care Agency was significant(r=.49, p=.0001). The relation between the score of the direct Perceived Social Support and Self-care Agency was significant(r=.50, p=.0001) and the relation between the score of the indirect Perceived Social Support and Self-care Agency was also significant(r=.40, p=.0001). In conclusion, it was found that higher score of the Social Support was a higher level of the Self-care Agency, especially the direct Perceived Social Support. The score of the Social Support and Self-care Agency was significantly differentiated according to economic status and school performance.

The Purpose of this study was to identify the level of learned helplessness and the relationship among variables affecting their learned helplessness. We have carried out research on 799 students. and collected data were analyzed using t-test, ANOVA, scheffe test, pearson's correlation coefficient. As a result, the mean score of learned helplessness was 2.55 (${\pm}.61$), Of the sub-domains, 'lack of control' was the highest with 2.85 (${\pm}.44$). And It was found that the helplessness was high in the case of poor fellowship, low academic achievement and poor family cooperation. These results were significantly correlated. Through the follow-up research, it is necessary to carry out management to reduce the learned helplessness by developing differentiated program that can reduce the learned helplessness of university students by identifying variables that can explain the learned helplessness of university students.

This study analyzes a relationship between Data Envelopment Analysis(DEA) efficiency scores and a normalization index in order to examine the validity of DEA models. A normalization index concerned in this study is 'sales per R&D project fund' which is regarded as a crucial R&D project performance evaluation index in practice. For this correlation analysis, three distinct DEA models are selected such as DEA basic model, DEA/AR-I revised model(i.e. DEA basic model with Acceptance Region Type I constraints) and Super-Efficiency(SE) model. Especially, SE model is adopted where efficient R&D projects(i.e. Decision Making Units, DMU's) with DEA efficiency score of unity from DEA basic model can be further differentiated in ranks. Considering the non-normality and outliers, two rank correlation coefficients such as Spearman's ${\rho}_s$ and Kendall's ${\tau}_B$ are investigated in addition to Pearson's ${\gamma}$. With an up-to-date empirical massive dataset of n = 482 R&D projects associated with R&D Loan Program of Korea Information Communication Promotion Fund in the year of 2011, statistically significant (+) correlations are verified between the normalization index and every model's DEA efficiency scores with all three correlation coefficients. Especially, the congruence verified in this empirical analysis can be a useful reference for enhancing the practitioner's acceptability onto DEA efficiency scores as a real-world R&D project performance evaluation index.

I paid attention to the fact that surrealism emerging in early 20th century has been resurfacing in the 21st century. It may be because of the increasing interest on the space showing the surrealistic features as people in these days prefer the experimental and dramatic space beyond repetitive daily life. I tried to identify the expressive characteristics in the interior space adopting the depaysement technique among a variety of expression techniques of surrealism. To this end, this paper selected 10 interior design projects by Fabio Novembre and Marcel Wanders since 2000s. As the methodology, chapter 2 examined the theories to identify the expression targets and approaches of depaysement around the art paintings. Next, the standard for case analysis in this paper was established by investigating the existing theses related to interior and space design with depaysement as the key word. The expressive characteristics of depaysement identified from the existing researches were classified into morphological, figurative, material and space program. Those programs were developed as the classification system in this paper. Chapter 3 described the design background and features of Fabio Novembre and Marcel Wanders. On the basis of the features and analysis framework identified in chapter 2 and 3, chapter 4 analyzed the features of depaysement observed in the works by both designers. The conclusion was presented in chapter 5. For the expressive characteristics of depaysement observed in the space by both designers, Novembre created optical illusion using distortion or overlap on the morphological aspect. Wanders showed mainly the feature of changing the scale. In accordance with the analysis on expression principles, the features including spatial continuity, ambiguity of border, visual amusement and uncertainty were differentiated in all spaces.

With the increased quality of life, the meaning of houses is shifting from a functional space for the simple purpose of residing to a symbolic space representing life as personality. Starting with the advancement of IKEA into Korea last year, global brands are about to enter into Korea. As Korean brands are not certain about how to set their direction in the situation where global brands have rushed into the market, it was thought that a key to solve the problem could be found from the cases of the lifestyle stores of Japan, which is moving one step ahead of Korea. Considering the circumstances, the author limited the subjects of this study to the lifestyle stores that have already established their brand identity and have prominent expressional characteristics of interior design in Japan. Research and analysis were conducted through site inspection and books. As a study method, literature and previous research were reviewed to find the program characteristics of interactivity and participation, the spatial characteristics of accessibility and the expressional characteristics of symbolism, scene continuity and function complexity, as the basis for an analysis. The results of the analysis showed that Japanese lifestyle stores are appealing to consumers as the spaces with their own differentiated space composition and various programs, by establishing their unique concepts and explicit brand identity. It is expected that such expressional characteristics of interior design will be of help in defining the direction of interior design of Korean lifestyle stores in the future.
