The objective of this study is to search for a theoretical and practical solution to the question of what is the most effective and qualitative method of information service for the college and university libraries in Korea. Assuming the maximum service or total service theory in information services, therefore, it appears natural that the subject specialist who is highly knowledgeable in his subject is indispensable in raising the quality of information librarians. The procedure of this research was as follows: There was no college and university library employing any full-time subject spceialist in Korea. This research, however, was proceeded on the assumption that subject specialists are already employed in all of the college and university libraries after the subject specialist system is established. The least qualification of subject specialist is limited, based on the criteria given by the foreign literature, to those who have master's degree in Library Science and bachelor's degree in any other subject area, those who have bacholor's degree in Library Science and master's degree in any other subject area, or those who have both bacholor's and master's degrees in Library Science with minor in any subject field . To prove the research hypothesis that the subject specialist will perform his role more efficiently than the generalist in effectively providing information service based on both accuracy and speed, this research as an obtrusive testing method analyzed the effectiveness by presenting information questions to the generalists and subject specialists who are information librarians in college and university libraries. For this study 20 librarians working at 12 university libraries were tested for performance levels of information services. The result showed $59.75\%$ an absolute performance rate and $75.20\%$ an adjust performance rate. Compared to Thomas Childer's 1970 study in which he used the unobtrusive testing method, these results were $5\%$ higher in the absolute performance rate and $11.36\%$ higher in the adjust performance rate. In comparing the generalist with the subject specialist in efficiency of information service, while the absolute performance rate was $57.08\%$ and the adjust performance rate was $73.08\%$ in the case of the generalist, the absolute rate was $63.75\%$ and the adjust rate was $78.38\%$ in the case of specialist, therefore, the efficiency of the subject specialist was $6.67\%$ higher in the absolute performance rate and $5.30\%$ higher in the adjust performance rate than that of generalist. But the factor of speediness was excluded from the analysis because of the difference between the time the interviewers recorded and the time the interviewee recorded. On the basis of the result of this research, it should be desirable to educate subject specialists and employ them as information librarians and for them to function as efficient subject specialists in order to improve the effectiveness of information services, the nucleus of the raison d'etre of college and university libraries.

The purpose of this study is to develop the Global Dynamic Computable General Equilibrium Model (Global CGE Model) in order to produce an economic impact analysis, including prospective obligations for the Post-2012 regime. This model explores the impact of an international emissions trading market and macroeconomic variables such as GNP, consumption, investment, imports and exports, in accordance with potential increased obligations on the Republic of Korea. Distinguishing it from existing studies, this Global CGE Model divides the global community into major economic groups, and in the capacity of the analyzed global model, reflecting the principle nations' macroeconomic indicators through the theoretical approach of endogenous growth theory. Policies such as an emissions trading scheme and carbon tax are reflected in the model. Also, in particular, the model reflects exogenous technological advances. According to this analysis, the stronger the greenhouse gas reductions, the greater the adverse effects on the economy; among macroeconomic indicators that appear, a significant decline is realized in the balance of trade, along with a significant decrease in investment and consumption. Energy dependence, in particular, plays a large role-varying in degree by industry type-, as greenhouse gas reductions would have a greater impact on energy-intensive industries. Furthermore, if Korea, currently recognized as a developing country, is given the obligation to reduce greenhouse gas emissions, competing countries such as China and other developing countries will be given an advantage.

The purpose of this study is to test the effect of pedagogical agent realism and expertise on persona effect. There were two perspectives of the pedagogical agents' social interaction. Self-identification hypothesis argues that complexity of agent image is better to increase social interaction. Subjective identification insists that simplified image is more helpful to facilitate social interaction. However, from the cognitive load theory perspective, learners' expertise can be a major factor to determine persona effect. Sixty-eight college students (male=19 and female=49) participated. The independent variables were the degree of realism of pedagogical agent (detailed vs. simplified image) and the expertise (high prior knowledge group vs. low prior knowledge group). The dependant variables were comprehension test and the agent persona instrument (API). There was no significant difference in comprehension test score; however, there were significant interaction effect on the most constructs of API: 1) facilitating of learning, 2) credible, and 3) human-like. The follow-up analysis of simple main effect revealed that high expertise group showed significantly higher perception of the three construct with high realism of pedagogical agent. The results of study show that learners' expertise plays a key role of perception of persona effect.

In this study, we examined how the United States, Chinese, and Japanese viewers perceive the morality of the main characters in the family drama 'Take Care of Mom' and the influence of the perceived morality has on drama enjoyment and quality evaluation. Results show that the viewers from all three countries evaluated 'Hoonjae' favorably and evaluated selfish older brother, 'Hyung Kyu', unfavorably. This means there are common norms that exist in all three countries for judging the good and evil in a drama. However, the main female characters that played opposing characteristics were evaluated differently from all three countries. This is because the relationship between parents and children, and the role of mother and woman were perceived differently from each country. These results support the argument that consumption of drama may differ by viewer's cultural background. Additionally, the research hypothesis that 'moral evaluation of major characters will influence the drama enjoyment and evaluation of the drama quality' was not supported in China and Japan, and was only supported by the U.S. viewers.

According to the Lighthill and Whitham's shock wave model, a shock wave exists even in a homogeneous speed condition. They referred this wave as unobservable- analogous to a radio wave that cannot be seen. Recent research has attempted to identify how such a counterintuitive conclusion results from the Lighthill and Whitham's shock wave model, and derive a new asymptotical shock wave model. The asymptotical model showed that the shock wave in a homogenous speed traffic stream is identical to the ambient vehicle speed. Thus, no radio wave-like shock wave exists. However, performance tests of the asymptotical model using numerical values have not yet been performed. We investigated the new asymptotical model by examining the implications of the new model, and tested it using numerical values based on a test scenario. Our investigation showed that the only difference between both models is in the third term of the equations, and that this difference has a crucial role in the model output. Incorporation of model parameter${\alpha}$ is another distinctive feature of the asymptotical model. This parameter makes the asymptotical model more flexible. In addition, due to various choices of ${\alpha}$ values, model calibration to accommodate various traffic flow situations is achievable. In Lighthill and Whitham's model, this is not possible. Our numerical test results showed that the new model yields significantly different outputs: the predicted shock wave speeds of the asymptotical model tend to lean toward the downstream direction in most cases compared to the shock wave speeds of Lighthill and Whitham's model for the same test environment. Statistical tests of significance also indicate that the outputs of the new model are significantly different than the corresponding outputs of Lighthill and Whitham's model.

Features of geological lineaments generally play an important role at the data interpretation concerned geological processes, mineral exploration or natural hazard risk estimation. However, there are intrinsically discordances between lineaments-related features extracted from surficial geological syrvey and those from satellite imagery;nevertheless, any data set contained those information should not be considred as less meaningful within their own task. For the purpose of effective utilization task of extracted lineaments, the mathematical scheme, based on fuzzy set theory, for practical integration of various types of rasterized data sets is studied. As a real application, the geological map named Homyeong sheet(1:50,000) and the Landset TM imageries covering same area were used, and then lineaments-related data sets such as lineaments on the geological map, lineaments extracted from a false-color image composite satellite, and major drainage pattern were utilized. For data fusion process, fuzzy membership functions of pixel values in each data set were experimentally assigned by percentile, and then fuzzy algebraic sum operator was tested. As a result, integrated lineaments by this well-known operator are regarded as newly-generated reasonable ones. Conclusively, it was thought that the implementation within available GISs, or the stand-alone module for general applications of this simple scheme can be utilized as an effective scheme can be utilized as an effective scheme for further studies for spatial integration task for providing decision-supporting information, or as a kind of spatial reasoning scheme.

The purpose of this study was to find out some factors affecting the social prejudice perceived by people with psychiatric disability(PPD) and to present some useful explanations for those effects based on theories from symbolic interactionism. The hypotheses were as follow. First, the higher the symptoms, the higher will be the perceived social prejudice of PPD. Second, if PPD have vocational roles, the perceived prejudice will be lower. Third, if PPD want more services or supports for vocational rehabilitation, the perceived prejudice will be higher. Fourth, the higher the perceived prejudice of family members, the higher will be the perceived prejudice of PPD. The results show that the major hypotheses were supported. Based on the results some theoretical and clinical implications are discussed. First, this study made a little contribution to the study of perceived social prejudice of PPD providing some useful theoretical basis and empirical evidences. Secondly, due to the limitation of the data and cross-sectional research the results of this study need to be duplicated under more rigorous experimental or quasi-experimental study. Concerning the clinical intervention, it should be stressed to provide valued social roles to help PPD protect themselves from social prejudices. Secondly, rehabilitation professionals need to help PPD cope with increasing perceived prejudice while pursuing valued social roles such as employee. Third, rehabilitation professionals should assess the perceived prejudice of family members and to help them resist social prejudices through education, self-help groups, and other advocating strategies. Lastly, professionals should be carful not to blame family members for the adverse effects of their perceived prejudice on PPD.

Class, the fundamental unit of school education and the meeting place of teacher and students, plays an important role in study of the subject matter of education. Class criticism is material to the theory or method that helps researchers deeply understand and analyze class phenomena or teachers' actions during a class. In this study, I make a critique on the features of a classic novel class as attempt to expand on new prospects in the field of research on classical literature education. The classic novel class in this class criticism is typical one, which reads the work analytically. Nevertheless, the teacher turns the students' vague repulsion into empathy and helps them appreciate and internalize the work. Students' empathy and response are reflected in the interpreting-centered class because the teacher's insights about the work and experience, knowledge, and method of literature education are projected during the class. Especially, a situation in which the teacher spends a relatively long time narrating the background of the work clearly shows the value and meaning disseminated in a classic novel class. Based on the aforementioned, attempts to collect a variety of cases of a classic novel class and to understand the meaning of these cases have to be part of future research. The research on the attributes of a class such as criticism of classic novels enables us to renew introspection to discover classical literature education.

If 1st order ZFC is consistent(has a model($M_1$)) it has a transitive denumerable model($M_2$). This leads to a paradoxical situation called 'Skolem paradox'. This can be easily resolved by Skolem's typical resolution. but In the process, we must accept the model theoretic relativity for the concept of set. This relativity can generate a situation where the meaning of the set concept, for example, is given differently depending on the two models. The problem is next. because the sentence '¬denu(PN)' which indicate that PN is not denumerable is equally true in two models, A indistinguishability problem that the concept <¬denu> is not formally indistinguishable in ZFC arise. First, I will give a detail analysis of what the nature of this problem is. And I will provide three ways of responding to this problem from the standpoint of supporting ZFC. First, I will argue that <¬denu> concept, which can be relative to the different models, can be 'almost' distinguished in ZFC by using the formalization of model theory in ZFC. Second, I will show that <¬denu> can change its meaning intrinsically or naturally, by its contextual dependency from the semantic considerations about quantifier that plays a key role in the relativity of <¬denu>. Thus, I will show the model-relative meaning change of <¬denu> concept is a natural phenomenon external to the language, not a matter of responsible for ZFC.

In the B2B context, recent research on how CSR builds the relationship between buyer and supplier has mainly focused the topic that establishing the long-term relationship asset. To fill this gap, the current study proposes a research model to examine how buyer's corporate social responsibilities(business and philanthropic CSR) affect supplier's new product creativity(internal capability) and its mediated link through trust and quality of information exchange. To test the hypotheses, responses were obtained from 197 marketing or buying managers in B2B firms. The empirical results confirm that both business and philanthropic CSR are positively related to trust. Second, trust also positively influences quality of information exchange. Finally, quality of information exchange has a positive relationship with new product creativity as internal capabilities of suppliers. The theoretical and practical implications of results and limitations of this research are discussed.
