사람에게 행동의 개인차가 있듯이 rat이나 mouse에 있어서도 행동의 차이를 발견할 수 있다. Rat의 행동성향에 따른 (1)학습 및 기억 능력의 차이, (2)기억과 해마의 관계, (3)치매유발단백질의 하나로 알려진 아밀로이드 베타($A{\beta}$ )및 수종의 항 치매 약물효과를 알아보는 것이 본 실험의 목적이다. Rat의 행동관찰을 통해 두 가지 행동패턴을 관찰할 수 있었는데, 이러한 rat의 행동 특성은 심리학자 Jung이 심리유형으로 설명하고 있는 extraversion, introversion의 행동성향과 유사할 것이라는 가정 하에 실험을 계획, 실시하였다. Rat에 water maze test를 실시하여 공간 기억의 단기, 장기 기억을 분석하였는데 그 결과 두 가지 행동 성향을 가진 rat은 서로 다른 학습 및 기억 능력의 특성을 보였다. 즉, extraversion은 단기 기억의 향상을 보인 반면에, introversion은 장기 기억의 향상을 보였다. Rat을 대상으로 water maze test 외에 Y-maze, passive avoidance test를 실시하여 공간 기억(spatial memory), 작동 기억(working memory), passive avoidance memory, 그리고 단기, 장기 기억의 관계를 종합적으로 분석해 보았다. 그 결과 두 가지 행동성향에 따라 서로 영향을 미치는 기억의 종류 및 관계에 차이가 있음을 발견할 수 있었다. 또한 두 가지 행동성향을 가진 rat에 약물을 투여했을 때, 서로 다른 약물 효과를 보였으며, $A{\beta}$ 를 주입했을 때, 기억(memory) 및 해마(hippocampus) 세포 사멸(cell death)에 서로 상반된 결과를 보여주었다. 이러한 연구 결과는 개체의 행동성향에 따라 학습 및 기억의 효과가 다를 수 있음을 보여주는 결과라 할 수 있고, 개인의 적성과 소질의 인식 및 개발의 중요성에 시사하는 바가 크다. 또한 개개인의 행동과 학습 및 기억 능력의 차이를 두뇌과학적으로 이해하여, 두뇌의 장점은 살리고 단점을 보완할 수 있는 이론적 토대를 세우는데 이러한 동물실험이 그 기초를 제공해 줄 수 있을 것이다. 또한 행동성향 및 기억의 종류에 따른 약물효과의 차이는 기억과 관련된 질병인 알츠하이머 환자에 있어 개개인에게 맞는 적절한 특징적인 치료약물이 존재할 것이라는 가능성을 제공해줄 뿐만 아니라 학습과 기억력 증진 효과를 기대해 볼 수 있을 것이라고 생각된다.

The fantastic has had various semantic layers between 'the Marvelous' and 'the Uncanny', these has been assorted by historical and synchronic aspects. The Marvelous has been harmonious and abundant world of fantasy which includes metaphysical system and all tradition of magical fence. The Uncanny has been a subversive fantasy world which shows absurdity and negative truths of this very world by modern consciousness. In comics, because of the media features, it is more useful the fantastic than the realistic. However, the relationship about comic and fantasy has rarely discussed in detail. So we has wanted to understand the specificities of affiliation with the Marvelous and with the Uncanny. Then it has been necessary to check the works of You, Sijin the comic book writer, for we ought to know how the affiliations with fantasy could influence each works' styles, and themes. You, Sijin started her works with sensibility of uncanny, but she tried to develop the theme "uptight" and devoted to establish "the Secondary World" stably. However, at Shin Meoung Ki(神明記) fantasy world overwhelmed the theme. After that, in The Closer and On, she crashed down the uptight feeing and made new self-consciousness by mixed fantasy style. The Closer and On has been the turning point of writer You, Sijin. Since than her works has showed a propensity for the Uncanny.

Recently, there has been a debate as to whether bioethanol should replace some portion of gasoline for fuels in South Korea, as energy security as well as climate change issues are rising as a significant national agenda. However, a considerable amount of subsidy will be required to compensate for the higher price of bioethanol-blended gasoline. In this context, government subsidy will obtain justification only when the positive social gains from consuming bioethanol for fuels can exceed the negative social costs. Through a nation-wide choice experimental survey, we examine if South Koreans have a positive value as well as non-linear preferences on substituting bioethanol for gasoline. The results reveal that the willingness to pay for purely domestic bioethanol-blended gasoline within 10% is about 52 KRW; Koreans have concave preferences on the blending ratio of bioethanol to gasoline. The turning point of the blending ratio of bioethanol was 6.5%. Also, we found inverse U-shaped curve between income and bioethanol choice probability and the turning point of the income was calculated as 250~299million KRW. Politically conservative propensity advocates uses of bioethanol blended gasoline, but awareness on bioethanol or more weights on environmental conservation have significantly negative effects on the choice of bioethanol. However, the design of the survey questionnaire is incompatible with the RFS of Korea and assumes orthogonality among the following four interrelated attributes: (i) domestic or offshore procurement of feedstocks in the case of domestic production, (ii) domestic production or import of bioethanol, (iii) the blending ratios, and (iv) the retail price increases. In addition, the results of model estimation and of model selection test are not definite. Hence, the results in this study should not be directly applied to the design of the specifics of the Korean RFS. Hence, the results in this study require cautions in applying to the design of the Korean RFS policy.

This study looked into Japan's recognition of Korea in early modern era with particular focuses on discourse on Korea and contents in textbooks in those days. In doing so, the topics of nationality, historical recognition, and social aspects in Korea were established and discourse on these topics in educational journals and the contents of textbooks and teaching manuals projected with such discourse were investigated. As for nationality, a strong propensity to negative recognition was clearly observed, represented by the words lazy, enervate, and uncivilized. They defined Korea's history of passive, other-directed nature and described such incompetent national management resulted in negative nationality. Their recognition of Korean history went further away, stating Korea was incapable of maintaining its independence and was a threat to peace of Japan and Asia, hence the forced merger by Japan. The criteria for Japan to assess Korean society were Western civilization and they defined Korean society as a pre-modern society with lower levels of civilization and culture. Discourse in Japan over Korea in early modern era were strongly influenced by Japan's pride as a modern state and its dominating ideology of imperialism and such discussions were spread among students through textbooks and teaching manuals.

This study analyzed a unique method of problem-handling, attitudes, and specific interest propensity in the career path of the type with inconsistency in the relative distance between personality type in Holland's hexagonal model. In-depth interviews and theme analysis with six clients who showed inconsistent personality type were conducted. These six were selected from 87 participants that had received training at the Korea Vocational Counselling Association, Korea Training Institute for Self-Sufficiency and Korea Employment Agency for the Disabled. From the analysis, the six clients with inconsistent 3 Codes showed four characteristics - more than three career experience, various interest pursuits, career involvement, and career identity. They were affected in their vocational behavior by their own Holland 3 Codes and showed vocational behavior very different from Holland's theory of person-environment fit approach. They showed positive, ambivalent and chaotic types on career identity. Furthermore, Conventional(C)-Investigative(I)-Social(S) 3 Codes type and Artistic(A)-Enterprising(E)-Realistic(R) 3 Codes type in the same inconsistent personality type showed different vocational behaviors in career path development, which relates to the meaning of Holland's 3 Codes. The significance of this research lies in its provision of various points for improving career counselling.

The consumption of foods rich in TDF should not be associated with impaired mineral absorp-tion and long-term mineral status. In surveys of populations consuming high amounts of TDF e.g Third World populations and vegetarinas gross deficiencies in mineral nutrition have not been noted. If mineral status is low among these groups it is most likely caused by the inadequacy or imbalance of the diet and not by the TDF. The key word is interaction which should be inte-rpreted in dietary imbalances that produce nut-rient deficiencies. There are no strong data to support the concept that TDF inhibits mineral absorption through a binding chelation mechanism. Limited data sug-gest that positively charged groups on polymers such as chitosan and cholestyramine will decrease iron absorption in humans and animals. Because TDF does not contain positively charged groups future research should be directed at the possible role of protein consumed along with TDF and the combination of effects on mineral nutrition Phytic acid is acknowledged as a potent chela-tor of zinc. However its association with zinc and its propensity to lower Zn bioavaiability may enhance the absorption of other elements notably copper and iron. The importance of interactions among nutrients including TDF will gain addi-tional attention in the scientific community. Soluble and insoluble dietary fiber function di-fferently in the intestine. Insoluble fibers accele-rate movement through the intestine. Soluble die-tary fibers appear to regulated blood concentra-tions of glucose and cholesterol albeit by some unknown mechanism. In creased viscosity produ-ced by the SDF in the intestine may provide an explanation of how this class of polymers affects plasma glucose cholesterol and other nutrients. Employing a double-perfusion technique in the rat we demonstrated that viscosity produced by SDF will delay transfer of zinc into the circulatory system. This delayed absorption should not be interpreted as decreased utilization. A great deal of additional research is required to prove the importance of luminaly viscosity produced by SDF on slowing nutrient absorption or regulating bllod nutrient homeostasis. Increased intake of TDF in the total human diet appears desirable. A dietary intake of 35g/day should not be considered to have a negative effect on mineral absorption. It is important to educate people that an intake of more than 35g TDF/day may cause an imbalance in the diet that can adve-rsely affect mineral utilization. Acknowledgments.

This paper examines the changing geography of producer service industries in the 1980s. The foci of this study are to analyze the regional distribution of each producer services, and to reveal the spatial linkage of producer services. Further this paper asserts the potential role of producer services for reducing the potential endogenous development in the periphery. During the 1981-86 period, producer service industries grew more rapidly than other service sectors and manufacturing sector. The main reason of the raid growth of producer services is attributable to an increase in demand for intermediate services from manufacturing firms. In order to compete an increasingly complex business environment, firms have expanded the amount of effort devoted to activities such as planning, coordination and control, and consequently have increased their use of producer services. The most distinctive feature of the location of producer services is spatial concentration into Seoul and surrounding region. Especially the degree of the concentration o business services into the Capital Region has been accelerating during the 1990s. The pattern of employment growth and regional distribution of producer services show a clear core / periphery disparity. Much of the regional inequality in producer services is largely due to variation in demand associated with the pattern of corporation headquarters with the pattern of corporation headquarters and branch plants location with large manufacturing firms. The analysis of spatial division of labor reflects that producer services are related to the location of headquarters in manufacturing industry. Headquarters in manufacturing firms and business service firms tend to cluster each other. Most of the headquarters spatially separated from branch offices are clustered heavily in Seoul. Especially headquarters of business services and insurance services are overwhelmingly concentrated into Seoul. The firms whose headquarters are located in Seoul have a linkage pattern on a nationwide scale. It is viewed have little potential for generating local multiplier effects and regional development. In the light of the result of this study, producer services are not likely to disperse soon to peripheral regions. Consequently the absence of policies directed at enhancing producer sevice in the periphery, concentration tendency would continue to reinforce the core's dominance at the expense of peripheral regions. From a regional perspective, the quality of a region's producer service sector is a key determinant of economic growth, since manu industrial location decisions are influenced by the differential availability of producer services among regions. Poor performance of producer services in peripheral regions seemed to be linked to the region's manufacturing base. Low-wage, standardized branch plants are not likely to induce the growth in knowledge intensive services associated with high-technology corporate headquarters. Producer services may help to create and attract new business including manufacturing firms, and also to enhance the productivity and competitiveness of local firms. Therefore the provision of service producing activities would be lead not only to generate and retain endogenous development but also to attract external firms, especially small and medium sized firms which have a lower propensity of internalized services. Hence, it may be more efficient to create and expanse new locally owned producer services rather than to attract branch plants of mult-locational firms in order to make indigenous economic development.

The ownership structure of a franchise system is determined by the franchisor's strategic choice. A close look at the extant theories and perspectives in economics and management such as resource scarcity theory, agency theory, transaction cost analysis, and mixed ownership theory reveals that firms choose their ownership structure for the sake of economic efficiency, profit potentials, the chance of survival, and other strategic concerns. The present study, on the basis of strategic choice perspective, reviews the divergent theories of a franchise system's ownership structure and its determinants, thus providing a theoretical framework for comparing the contradictory arguments along the several critical dimensions. We also developed and tested the conflicting hypotheses regarding key determinants of ownership structure including firm's age, size, transaction-specific investments, uncertainty, and risk-sharing propensity. Using a FDD (Franchise Disclosure Document) data set of 543 Korean franchisors, we found that the years in business, the total number of employees, days of training, the inverse of the years of franchising, and the requirement of royalty payment have positive relationships with the proportion of company-owned outlets to total number of outlets. On the other hand, the proportion of company-owned outlets was found to have negative relationships with the total number of outlets and the extent of geographic dispersion of outlets, but to have no significant relationships with the initial investment required and the inverse of contract length. Based on the findings, we provide several theoretical and managerial implications for studying ownership structure of franchise systems.
