This study attempts interpretation of the elements of transcendental fantasy appeared in animation. It is about the characteristics of the different spaces from the reality appeared in animation created out of imagination. In regard to the reason why such aspects of fantasy elements appeared in the whole work appear, it presents the three structures including divisional, fantasy and comprehensive structures and characteristics of spatial images of imagination presented in Gilbert Durand's "Les Strutures anthropologiques de l'Imaginaire", through visual nature, depth, and maldistribution. Thus, this study examines the elements in animation . Transcendental fantasy elements give abstract concepts to certain images as it specifically describes them in reality. The fantasy elements operate when it is viewed through the sensibility of the characters. This study attempts to closely approach the issues on how fantasy elements operate in animation.

This study analyzes the interaction of variables consisting of the local finance system based on the theory of system thinking regarding how financial decentralization can be understood as the political means for local decentralization and why it is needed. The results gained from this research are as follows: first, variables consisting of the local finance system form interactional relationship in the significant level, and it has been found that rapid growth and rapid decline repeat with five positive feedback loops as the center. Second, strategic points for the validity of local finance decentralization were discovered through causal map modeling. In particular, it has been shown that the virtuous cycle structure declines the local finance system through the constant operation of variables (government subsidies, taxation for real estate transactions, central government's local finance mediation system, and local government debt, etc.) that deteriorate the vicious cycle structure. Based on this, strategic policy tasks were drawn. It is expected that this study will help the understanding of the local finance system and increase academic width for local finance from the aspects of general knowledge, not the knowledge about local finance decentralization.

During the last decade, the private sector computer classroom contributes toward the ICT education and the expansion of educational IT infrastructure for school. The matter of after school that goes into effect beginning for the next year however, is increased more and more because there are not enough to discuss on the after school. Some people confuse the role of After-school Computer Classroom with computer science education of school. We should evaluate the contribution of the private sector computer classroom and find out the necessity due to the results. And we should explore the direction for solution on problems pedagogically. In this study we present the models that improve the current problems of private sector computer classroom according to the pedagogical role and the improvement direction for after school.

The purpose of this study is to find the appropriate probability distribution representing the size distribution of suspended cohesive sediment. Based on goodness-of-fit test for a significance level of 5% using the Kolmogorov-Smirnov test, it is found that the floc size distributions measured in laboratory experiment and field study show different results. In the case of sample data collected from field experiments, the Gamma distribution is the best fitting form. In the case of laboratory experiment results, the sample data shows the positively-skewed distribution and the GEV distribution is the best fitted. The lognormal distribution, which is generally assumed to be a floc size distribution, is not suitable for both field and laboratory results. By using 3-parameter lognormal distribution, it is shown that similar size distribution with floc size distribution can be simulated.

Although construction site photos contain important as_built information, technique and knowledge, there has been lack of frameworks to store and manage construction site photos efficiently and effectively. The problems in site photo management are getting increasingly serious, as digital cameras are adapted as collection tools of site Photos. This research suggests an information framework(named CIIM: Construction Image Information Model) to manage and share construction information based on 5W1H in order to derive construction context, which includes technologies, lessons-teamed and knowledge, from construction site photos, and a site photo management system named CIMS II (Construction Image information Management system II was developed to verify the model. It is expected that the results of this research that are an information framework and an system could help more effective classification, management, search and derivation of context in a construction project.

Researchers have shown the negative compatibility effect (NCE) consistently using arrows. However, they provided inconsistent interpretations about the reason why the NCE happens. The purpose of the present study is to test the factors suggested to be critical for the NCE including automatic inhibition, updated information and top-down control. Presented with arrays of masked prime and targets composed of colored double-headed arrows, participants demonstrated invulnerable NCE on the basis of direction of arrows in the judgment of direction with corresponding hands (Experiment 1), with reverse-mapping hands (Experiment 2) and even in the color-judgment task (Experiment 3). These results imply that the main sources of NCE might be perceptual dominance and inherent properties of stimuli and responses; this contrasts with previously proposed explanations.

We analyze trade and balance records of 10,000 stock investment accounts of individual investors for the period of 1998 to 2003. Individual investors em an annual gross return of 12.3% while the KOSPI and the value weighted composite including KOSDAQ stocks yield 13.6% and 9.7% respectively during the same period. Net return performance is 8.3%, a drop of 5.3% mainly due to heavy trading. Individual investors' annual turnover amounts to over 270 percent. In an analysis of groups formed on the month's end position value, the performance of the top quintile is found comparable to the market while the rest yield significantly lower risk-adjusted returns than the market. We also find evidence rejecting the rational expectation model while supporting the overconfidence hypothesis which states overconfidence leads to a higher level of trading, resulting in poor performance. Individuals tilt their stock investment toward high-beta, small, and value stocks.

본(本) 연구(硏究)는 한국증권시장에서 대표적 대용시장(代用市場)포트폴리오인 한국종합주가지수(韓國綜合株價指數)와 동일가중지수(同一加重指數)의 효율성에 대한 검증을 Hansen(1982)의 다변량의 GMM에 의하여 실시하고자 하였다. 이를 위하여 먼저, 주식수익률자료(株式收益率資料)에 근거한 산업별(産業別)포트폴리오수익률과 초과시장수익률모형(超過市場收益率模型)의 오차항(誤差項)이 정규분포(正規分布)를 벗어남을 증명함으로써 GMM검증방법(檢證方法)의 정당성을 찾고자 하였다. 정규분포에 대한 검증방법(檢證方法)으로서 왜도와 첨도의 검증과 이를 결합한 Jarque-Bera(1980)검증(檢證)을 실시하였다. 둘째로, Hansen(1982)의 GMM을 대용시장(代用市場)포트폴리오의 효율성(效率性) 검증(檢證)에 적용하는 방법에 대한 연구들인 Mackinlay-Richardson(1991), Harvey-Zhou(1993)와 Campbell-Lo-Mackilay(1997) 등을 기초로하여 이들의 방법론을 개선한 3가지의 효율성(效率性) 검증방법(檢證方法)을 제시하였다. 셋째로, 이상의 검증방법(檢證方法)들을 토대로 1980년 1월부터 1997년 6월까지 월별주식수익률(月別株式收益率)의 자료(資料)를 11업종으로 분류하여 산업별(産業別)포트폴리오수익률(收益率)과 초과시장수익률모형(超過市場收益率模型)에 의한 오차항(誤差項)이 정규분포(正規分布)를 따르는지와 아울러 대용시장(代用市場)포트폴리오의 효율성을 검증하였다. 검증결과(檢證結果), 산업별(産業別)포트폴리오수익률과 오차항(誤差項)은 대부분 정규성이 기각(棄却)되어 GMM검증방법(檢證方法)의 정당성이 입증되었다. 따라서 GMM에 의한 효율성(效率性)을 검증한 결과, 한국종합주가지수(韓國綜合株價指數)의 경우에는 평균-분산(平均-分散)프론티어(mean-variance frontier)상(上)에서의 대용시장(代用市場)포트폴리오의 효율성(效率性)은 기각(棄却) 할 수 없는 것으로 나타났으나 평균수익률(平均收益率)이 GMVP의 수익률보다 낮았기 때문에 효율적(效率的) 프론티어(efficient frontier)상(上)의 대용시장(代用市場)포트폴리오의 효율성(效率性)은 기각(棄却)되어 대용시장지수로서의 문제점이 있는 것으로 나타났다. 그러나 동일가중지수(同一加重指數)는 평균수익률이 GMVP의 수익률보다 높을 뿐만아니라 효율적(效率的) 프론티어상(上)의 대용시장(代用市場)포트폴리오의 효율성(效率性)도 채택되어 한국종합주가지수(韓國綜合株價指數)보다 우월한 지수(指數)인 것으로 나타났다.

This study aims to analyze why South Korea has not used audit system but examination system and suggest policy reform for the system on the institutional context perspective. Institutional context is structured down to institutional legacy, motives, institutional constraints, actors' roles, and changed institution. I researched the literature on the subject and collected research materials from the Department of the Treasury and Audit Office website of New Zealand, Australia, United Kingdom, United States and South Korea. These were analyzed using for suggesting realistic and effective policy. Analysis showed that South Korea has used examination system due to institutional constraints and tried to increase reliability of financial statements by enlarging the meaning of examination, strengthening the ability of the Board of Audit and Inspection, enacting government examination standards, and making a comprehensive public announcement. Comparing with other countries where government audit systems are applied, there are still some vulnerable points in South Korea. In order to make up for the shortcomings, this study suggests several points: strengthening the ability of actors; systemizing internal control; expressing opinion; making a more comprehensive public announcement. It would be desirable for making further detailed studies of the points.

This study analyzed the spatial interrelation between living wages and economic variables and how they operate based on systems thinking theory to understand what value living wages have as policy instruments and why they are necessary. Results from this study can be summed as follows. First, the relationship between living wages and economic variables shows close interaction at a considerable level. In particular, mutual feedback which connects to laborers' standards of living, consumption, business, and economy was operating closely. Second, largely three positive (+) feedback loops were operating in the feedback structure of living wages and economic variables. This can be interpreted to mean that positive economic variables which are associated with living wages have the possibility of growth. Also, it can mean that the minimum wage system did not fully fulfill its role. Through these study results, it can be learned that living wages have sufficient value as a policy means and that it is advisable to allow living wages to exceed simple application levels in the public sector to expand into the private sector, to bring positive change to the economic system.
