The purpose of this study was to examine How the exploratory activities using Excel and GSP which are exploratory software, in learning analytic geometry affected on the underachievers' analytic geometry concept development process. The subjects of 5 students who received the 8th~9th grades from their examination of the last semester, participated in a total of 7 units based on Skemp's intelligent learning model. The results of the study showed that there were two important cases found to nearly achieve the category $R_2$. One was reflective thinking could happen through exploratory software in category $R_1$. The other was the exploratory activities which could have the same effectiveness as the relational understanding in category $I_2$, as Skemp mentioned that there is a room to be achieved in the elementary level when such relational understanding is achieved.

In this study, the use of '心' letter used in classic Chinese book of 『Hwangjenaegyeog』 and its meaning was examined. In Chinese letters, '肉' is a sign that symbolizes the body. The letters '肝', '脾', '肺', and '腎' expressing the five human organs all contain the form of '肉'. So they don't cause semantic confusion. However, the Chinese letter that means heart and mind are written as '心'. As a result, it is difficult to understand the meaning of '心'. In addition, the contents of 『Hwangjenaegyeog』 cover various fields from disease to astronomy. For this reason, a total of 286 '心' letters used in it have various meanings. The results of this study are as follows. First, it means human heart. Second, it means the human chest. Third, it refers to mind. Fourth, it means a transcendent concept like spiritual enlightenment. Fifth, it refers to pericardium. Sixth, it refers to logical thought Seventh, it means center or core, and finally does constellation. in the eastern sky of ancient Asia. The results of this study are thought to be helpful in grasping the meaning of '心' in the classical literature as well as in 『hwangjenaegyeonglyeongchu』.

In terms of business, forecasting is a work of what is expected to happen in the future to make managerial decisions and plans. Therefore, the accurate forecasting is very important for major managerial decision making and is the basis for making various strategies of business. But it is very difficult to make an unbiased and consistent estimate because of uncertainty and complexity in the future business environment. That is why we should use scientific forecasting model to support business decision making, and make an effort to minimize the model's forecasting error which is difference between observation and estimator. Nevertheless, minimizing the error is not an easy task. Case-based reasoning is a problem solving method that utilizes the past similar case to solve the current problem. To build the successful case-based reasoning models, retrieving the case not only the most similar case but also the most relevant case is very important. To retrieve the similar and relevant case from past cases, the measurement of similarities between cases is an important key factor. Especially, if the cases contain symbolic data, it is more difficult to measure the distances. The purpose of this study is to improve the forecasting accuracy of case-based reasoning approach using fuzzy relation and composition. Especially, two methods are adopted to measure the similarity between cases containing symbolic data. One is to deduct the similarity matrix following binary logic(the judgment of sameness between two symbolic data), the other is to deduct the similarity matrix following fuzzy relation and composition. This study is conducted in the following order; data gathering and preprocessing, model building and analysis, validation analysis, conclusion. First, in the progress of data gathering and preprocessing we collect data set including categorical dependent variables. Also, the data set gathered is cross-section data and independent variables of the data set include several qualitative variables expressed symbolic data. The research data consists of many financial ratios and the corresponding bond ratings of Korean companies. The ratings we employ in this study cover all bonds rated by one of the bond rating agencies in Korea. Our total sample includes 1,816 companies whose commercial papers have been rated in the period 1997~2000. Credit grades are defined as outputs and classified into 5 rating categories(A1, A2, A3, B, C) according to credit levels. Second, in the progress of model building and analysis we deduct the similarity matrix following binary logic and fuzzy composition to measure the similarity between cases containing symbolic data. In this process, the used types of fuzzy composition are max-min, max-product, max-average. And then, the analysis is carried out by case-based reasoning approach with the deducted similarity matrix. Third, in the progress of validation analysis we verify the validation of model through McNemar test based on hit ratio. Finally, we draw a conclusion from the study. As a result, the similarity measuring method using fuzzy relation and composition shows good forecasting performance compared to the similarity measuring method using binary logic for similarity measurement between two symbolic data. But the results of the analysis are not statistically significant in forecasting performance among the types of fuzzy composition. The contributions of this study are as follows. We propose another methodology that fuzzy relation and fuzzy composition could be applied for the similarity measurement between two symbolic data. That is the most important factor to build case-based reasoning model.

This study is the text discourse of agenda setting through media policy on the three communities. The materials of subjects are the 71 text discourses that appeared in the columns, the special manuscripts, and the comments on the contemporary topics in 33 media. The subjects focuses on the metaphor, metonymy, and binary transposition. This kind of connotation tends to be imploded into people through media, so that it produces hyperreality. This process produces the regulation and strengthens the reality through the circuit of culture. Thus this research tries to develop the theoretical foundation for analysing the text discourse produced by the media. Also it focuses on widening the research scope to study the effects that the circuit of culture provides on the politics, society, and economics. Therefore The first, the objective meanings(denotation)which the referents of the community as T'PALACE, I'PARK, and STARCITY are 'larger scale', 'high and skyscraper', 'the rich people and the plutocrats who have very high academic career' and ' the residence place for the famous stars and successful CEOs', etc. and the subjective meanings, connotations which the referents of the community are 'The first street' transposes '1%' 'their own space' into the characteristics of the wealth of Gangnam district or Korean wealth', the additional significations which the metaphors such as 'the noble community', 'the sample for the high -level residential space', and 'the greed of 1%'. Conclusion, The significations of the symbols became imploded into the population and circulated along with the cultural streams through the media. The referents are recreated and consumed among the other communities such as the named 'PALACE', 'I'PARK', 'STARCITY' in the other areas. This kind of ideology tends to create the myths such as 'the 1% rich people of Gangnam', 'the first street of Korean wealth', and create the regulation such as 'the compound taxes for the real-estates', 'the policy of reducing the taxes for the rich', 'the policy of reducing the taxes for the 1% of the rich'. Also these regulations make the politicians operate new policies and are being utilized as 'slogan' for the politicians.

The Internet of Things (or IoT for short) which refers to uniquely identifiable objects and their virtual representations in an Internet-like structure is to be reality today. The amount of data on IoT is expected to increase abruptly and there are several key issues like usefulness interoperability between multiple distributes systems, services and databases. In this paper a methodology is proposed to realize a recently developed cloud service model, Contents as a Service (CaaS), which is contents delivery model referred to as 'on-demand contents'. In the proposed method, the global object identification, ePosition, comprising the structured form of two sorts of text strings with a separation symbol like # is applied to identify a specific content and registered with the content at the same server. It is easy-to-realize and effective to solve the interoperability problem systematically and logically. Some APIs for the proposed CaaS service are to be converged to provide some upgraded cloud service model such as 'CaaS supported SaaS' and 'CaaS supported PaaS'.

This study is to investigate the problem solving styles according to the left /right brain preference among earth science gifted students. We took the R/LCT and the test of BPI to investigate the brain preference of earth science gifted students (N=16), and took S-CPST to investigate the problem solving styles on them. In the R/LCT, the earth science gifted students were classified into 3 groups (8 left-brain preference students, 7 right-brain preference students, 1 middle-brain preference student). In the BPI, 8 students had the appearance of left-brain preference, whereas 8 students had the appearance of right-brain preference. According to the result of S-CPST, first the left brain preference students tended to resolve a problem into simple components, then they put together each simple component. They prefer to solve a problem using numbers and mathematical signs logically, but they were afraid of giving trouble to describe own idea with pictures. Whereas the right brain preference students solved a problem with 3 steps. First, they saw an overall form of problem. Second, they tried to analyze each simple component of it, and then, made up all in one. Also, the right brain preference students observed the intuitive pattern of problem first, and then suggested the various problem solving methods later, and they took a solving plan using a picture in detail. In sum, earth science gifted students are unequal in problem solving styles according to the left/right brain preference. Thus, a teaching-learning method needs to be developed based on left/right brain preference for more effective gifted education.

Animation which appeared with films in the late 19th century was a medium which came on obtaining nourishment from art historical style of modernism. However, the relation establishment between animation and modernism has been focused mainly on animation shapes, namely painted images. This sprang from explaining the relationship between animation and paintings, and for this reason, discussions of movements in animation were understood in tradition of chromophotograph of Muybridge and Jules Marey, or some characteristics owned by the live-action film. However, movements of animation were essentially different from the indexical sign of films or photogram, and objects of reproduction were different between them. Movements reproduced by animation are not ordinary movements, but expressions of or compressed movements and considerably systematic movements. As a result, these movements are far from reproduction of live-action film photogram. Rather, the logic of movements reproduced by animation comes near to controlling their motion scopes, time, distance etc. after dividing each part of the body. This is concluded in a standpoint of modern mechanism which is represented by Descartes and La Mettrie who tried to understand human body as a exchangeable machine. Design of modern mechanism ranging from modern society to industrial society and the age of modernism came to lead to analysis of physical motions of modern industrial society called composition of efficient movements understanding them as the law of nature rather than movements as nature. In the late 19th century, Taylor, F. W. and Gilbreth, Frank Bunker's studies of workers' working hours and 'motion study' were a way of constituting the frame of machine-human, which indicates that tradition of modern mechanism affected the entire modernism passing through industrial society. Further, we can see that motion studies conducted by them have almost similar characteristics to action analysis to study animation later in the name of 'timing'.

현재 공적연금제도의 하나인 사학연금은 일반 민간 기업에서 퇴직시에 지급하는 퇴직금과 유사한 성격의 '퇴직수당' 급여를 지급하고 있다. 사립학교연금법에서 지급하고 있는 퇴직수당제도는 학교법인인 사용자가 지급할 의무가 있는 급여에 해당한다. 그러나 사립학교의 열악한 재정으로 인하여 학교법인이 지급하지 아니하고 이를 국가와 공단 및 대학의 일부가 이를 분담하여 지급하고 있다. 사학연금공단에서는 매년 236억원을 연금기금에서 지급하였으며, 동 금액은 기부금으로 손금산입되어 왔다. 그러나, 최근 들어 기부금의 손금 인정비율이 50%로 축소되어 실제 법인세를 납부하고 있다. 본 연구에서는 이러한 퇴직수당 공단부담금을 공단에서 부담하는 것이 타당한지 여부와 기부금으로 처리되는 것에 대한 타당성 여부 등에 대하여 세무회계적인 접근을 통해 법인세제개선을 위한 법 개정의 타당성을 살펴보고자 하였다. 본 연구는 퇴직수당 공단부담금이 기금회계에서 지급되어 기부금으로 보고 있는 기존의 예규에 대한 해석을 새롭게 하고 사학연금기금의 세무회계상 개선방안을 도출하고자 하였다. 퇴직수당의 급여지급은 엄밀하게 살펴보면 기금회계의 대상이 아니라 연금제도의 고유사업인 연금회계의 대상으로 보는 것이 타당하다. 이와 같은 현행 공단의 회계처리 및 기금회계 과세대상의 문제점을 인지하고 이를 면밀히 분석해보고자 한다. 본 연구는 사학연금기금의 법인세 부담으로 인한 연금재정악화를 사전에 방지할 뿐만 아니라 사학연금기금에 대한 안정화를 도모하고자 하는 방안 연구의 일환으로 법적 개선안 도출을 목적으로 하고 있다. 공단은 사립학교 법인을 대신하여 공단에서 대신 지급하면서도 이에 대해 기부금으로 보는 규정으로 인해 법인세를 납부하고 있어 부담금을 대신하여 납부하면서 법인세도 부담하고 있는 이중부담을 안고 있는 것이다. 본 연구에서는 이와 같은 사항을 토대로 다음과 같이 개선방안을 제시하고자 한다. 우선, 공단내부회계규정의 수정을 통해 퇴직수당의 연금회계 적용을 주장하고자 한다. 퇴직수당제도는 연금급여와 관련된 것으로 비과세대상의 고유목적사업 회계에 해당됨에도 불구하고 퇴직수당을 기금회계에서 기부금으로 처리하는 것은 법 논리상 타당하지 않다고 본다. 둘째, 학교법인을 대신하여 기금에서 대신 지급하였다는 것은 연금제도를 유지하기 위해서 연금법상에서 강제로 부과된 부담금으로 이를 필요경비로도 보아야 한다. 셋째, 학교경영기관이 마땅히 부담하여야 할 부담금임에도 불구하고 사학연금기금에서 부득이하게 지급하고 있음을 감안하여 퇴직수당부담금은 현행의 법인세법상 기부금 한도초과 대상에서 제외하는 특례규정을 신설하는 것이다. 본 연구는 최근 법인세가 과세되고 있는 사학연금기금의 과세 문제점을 살펴보고 이에 대한 개선방안을 제시하였다는 점에서 기존 연금제도의 틀 안에서 퇴직수당제도의 법적 부담을 검토한 연구와는 달리 법인세법상의 세무적 검토를 하였다는 점에서 의의가 있다고 할 수 있다.

Raquel, the representative work of Vicente García de la Huerta, an 18th century Spanish playwright achieved theater box-office success and popularity during staging. It has been evaluated by many scholars and critics as the ideal drama that faithfully followed the norms of neoclassicism, which pervaded the aesthetic mainstream at the time. However, the factor that enabled the popular success of this theater production was its ability to harmonize the themes or contents with a traditional play to meet the unique trends and tastes of Spanish viewers who were still appreciated earlier Baroque theater, rather than complying with external norms of neoclassicism such as principle of three unities or exclusion of comic figures etc. That is, Spanish viewers of the time thoroughly rejected theater of neoclassicists who attempted to unilaterally enlighten them while regarding the Baroque theater of earlier times as full of superstition and irrationality, illogic and disorder, regardless of their own dramatic taste. In this situation, Huerta's tragedy Raquel, achieved the harmony of neoclassical tragedy and Spanish theatrical tradition. It thus emphasizes the importance of public support and sponsorship in dramatic success. Traditional dramatic elements shown in Raquel can be summarized as honor, poetic justice and love and these elements are major dramatic codes penetrating the entire Baroque theater of Spain.
