This essay is a study aimed at rationality and utility of two terms, 'Nongak' and 'Pungmul'. I examined how the terms have been today, by diachrony based on review of historical material. I tried to secure the historical context and basis about my argument, quoting many historical material from Korea Dynasty period, Joseon Dynasty period and the colonial period of the imperial Japan during 1910-45 to today. I examined many objective arguments about the 'Nongak', and pointed out the mistake of the objective argument. And I examined the means and rationality of the terms, 'Nongak', 'Pungmul', 'Pungmulgut', 'Pungmulnory'. The 'Pungmul' has been used as the means of instrument for a long time from Joseon Dynasty period. It is only rational using as the means of instrument but as the means of Performance of Nongak considering the historical legitimacy. The 'Pungmul' is Sino-Korean word, not korean native letter. The Pungmulgut means the 'ritual by Pungmul', so it can be recognized the rationality, but have a weak point that it is a neologism being made by some intellectuals in 1980s. In addition to, it is not used im performing field. 'Pungmulnory' has a limit to call the Nongak as a synthetic art. 'Nongak'means a synthetic art that farmers who were absolute majority in agrarian society of Korea have made and developed. So I conclude that 'Nongak'is the best rational term.

The purpose of this study was to compare rock descriptors used by students in two different task contexts and to suggest the characteristics of a task suitable for learning of rocks. Twenty-four 3^rd grade students were given descriptive and inferential tasks about three types of sedimentary rocks, and the rock descriptors used by the students were analyzed from a resources-based view (RBV) about students' conceptions. The result showed that the number of students using everyday descriptors to describe properties of the rocks and the frequency of using the everyday descriptors decreased in the inferential task. It was also revealed that the students using disciplinarily more appropriate descriptors were more likely to infer the process of rock formation in scientifically valid ways. By contrast, student inferences lacking scientific validity were mostly those that used everyday descriptors to express properties of the rocks. Based on these findings, it was concluded that inferential tasks would be suitable for student learning of rocks which is to be authentic to the essential features of earth science practices.

In this paper, a geometric nonlinear analysis procedure of the beam-column element including multi-noded cable element in extension of companion paper (Kim et al., 2005) is presented. First, a stiffness matrix was derived about the beam-column element that considers the second effect of the initial force supposing the curved shape at each time-step, with Hermitian polynomials as the shape function. Second, the multi-noded cable element was also subjected to the tangent stiffness matrix. To verify the geometric nonlinearity of this newly developed multi-noded cable-truss element, the Innovative Prestressed Support (IPS) system using this theory was analysed by geometric nonlinear method and the results were compared with those produced by linear analysis.

2010년 12월 8일 국회 본회의에서 "친수구역 활용에 관한 특별법"(이하 친수법)이 통과되었다. 친수법은 국가하천의 양안 2km 이내의 지역을 엄격한 기준에 의해 친수구역으로 지정하여 체계적으로 개발하도록 제도화하였다. 또한 특히 사업시행자를 공기업 및 지방자치단체 등 공공기관으로 제한하고 개발이익도 하천정비에 재투입하여 개발이익이 사유화되거나 이윤추구의 장이 되지 않도록 하는 법적 토대를 마련하고 있다. 우리나라의 하천은 지난 수십 년간 개발일변도 정책으로 하천 본래의 모습을 찾기 어렵다. 인구의 도시집중, 지속적인 개발, 하천에 대한 기대치 증가 등으로 앞으로도 하천 자체의 자정능력에 의한 회복은 기대하기가 쉽지 않다. 4대강 살리기 사업(이하 4대강사업)은 국내 하천의 이러한 절실한 현실이 고려되었다고 한다. 그런데 4대강사업으로 조성되는 수변지역을 그대로 방치하면 무분별한 난개발과 토지투기의 장으로 전락할 가능성이 크다. 또한 수변구역 주변의 넓은 토지는 이미 농경지화되어 있어 비료, 제초제 등 비점오염원의 하천유입으로 수질을 지속적으로 위협하고 있다. 이러한 제반 여건들이 친수법 제정의 주요한 동기가 되었다고 한다. 그러나 친수법의 제정에는 수많은 우여곡절이 포함되어 있다. 친수법은 법안이 발의된 이래 법안의 취지를 둘러싸고 향후 법 실행과 관련된 논의가 첨예하게 대립하여왔다. 본 연구는 이미 제기된 특별법의 문제점에 대하여 법적인 관점에서 짚어보고, 그에 따른 개선방안을 모색해 보고자 한다. 친수법의 제정을 위하여 꼭 특별법이라는 입법과정을 거쳐야 했는지 그리고 친수법이 상정하고 있는 사업의 성격 및 내용에 대한 법적인 타당성을 살펴보고자 한다. 또한 친수법 제4장에서 규정하고 있는 하천관리기금을 법률 구성의 입장에서 어떻게 파악할 수 있는지에 관한 점도 고찰하였다. 즉, 친수법이 구상하고 있는 [특별법의 제정${\rightarrow}$친수구역 개발에 의한 수익 창출${\rightarrow}$하천기금의 조성${\rightarrow}$건전한 하천관리]의 구도가 법적으로 어느 정도 균형과 조화를 이룰 수 있는지 고찰하였다.

This study reviews the issue of endogeneity which has gained in importance in the empirical accounting researches in recent years. In so doing, I aim to call attention to the extent to which the presence of endogeneity limits the validity of empirical testing of models. More specifically, this paper explains what endogeneity is, its causes and consequences, and potential ways of managing the problem. The issues that concern endogeneity include, in the main, omitted variables, simultaneity, equilibrium conditions, choice variables. In this paper, I also discuss the implications derived from several selected empirical accounting research topics, that explicitly dealt with the problem of endogeneity. These include, among others, Oswald and Zarowin's (2007) study on the informativeness of capitalization of R&D, Hazarika et al. (2012) focusing on the relationship among internal corporate governance, CEO turnover, and earnings management, and a series of literature devoted to the associations between corporate governance structure and firm values. Finally, possible approaches for dealing with endogeneity are discussed.

When analyzing the scatting problem of multi-layered planar structures using closed-form Green's function, one of the main difficulties is that the numerical integrations for the evaluation of diagonal matrix elements converge slowly and are not so stable. Accordingly, even when the integration fur the singularity of type $e^{-jkr}/{\gamma}$, corresponding to the source dipole itself, is performed using such a method, this difficulty persists in the integration corresponding to the finite number of complex images. In order to resolve this difficulty, a new technique based upon the Gaussian quadrature in polar coordinates for the evaluation of the two-dimensional generalized exponential integral is presented. Stability of the algorithm and convergence is discussed. Performance is demonstrated for the example of a microstrip patch antenna.

The purpose of this study is to provide academic and practical implications through empirical analysis on the moderating role of SHRM that is relatively lacking in the relationship between CLMRC and performance. In order to achieve the research purpose, data were collected from 123 CEOs of Korean companies. The reliability and validity of the collected data were examined and the hypothesis was verified by hierarchical regression analysis. The results of this study show that CLMRC has a meaningful positive(+) effect on both net profit and sales per person, and SHRM has shown to have a moderating effects between CLMRC and sales per person, CLMRC and net profit. Through this analyzes, CLMRC can enhance the management performance, and in this process, the more strategic the human resource management(HRM) is, the more the impact on the management performance is strengthened. Implications for CLMRC and SHRM, limitations of the study and suggestions for future researches are discussed.

In this study, twenty-eight 7th graders were interviewed to explore their emotional responses and perceived teaching-learning strategies for effective conceptual change by the types of cognitive responses to a discrepant event. The results revealed that cognitive conflict was more induced by a discrepant event when its reliability and validity were emphasized. The students' cognitive responses to a discrepant event, the existence of alternative hypotheses, and their clearness influenced the patterns of emotional responses such as interest and anxiety. Many students perceived that emotional responses would have positive influences on concept learning processes. In the cases of the students exhibiting cognitive responses such as belief decrease, peripheral belief change, and belief change, opinions about teaching-learning strategies for effective conceptual change were different depending on whether they had alternative hypotheses or not. Educational implications are discussed.

This study is to conduct the basic study for the achievement and assessment standards for the subject of 'Human Development' and 'Food and Nutrition', which are the curricula of Vocational Home Economics High Schools. These two subjects were newly adopted in the Vocational study Section of the 2005 College Entrance Examinations. In other words, this study is to provide the basic data for implementing the quality education based on the proper assessment of the curricula. For this purpose. this study analyzed the character & objective of 'Human Development' and 'Food and Nutrition'. Secondly. through the theoretical review for the concept & necessity of absolute evaluation standards. this study ensures the concept of achievement and assessment standards. and also designs the developing measures (including procedures). The achievement standards were developed by the following 5 step procedures. (1) Analyzing the objectives & contents of curricula. (2) Designating the development field of achievement standards (3) Developing the achievement standards. (4) The assessment of achievement standards. (5) Confirming the achievement standards. The assessment standards were developed by the following 5 step procedures. (1) Analyzing the achievement standards, (2) Designating the assessment field (3) Developing the assessment standards (4) Evaluating the assessment standards (5) Confirming the assessment standards Thirdly, this study suggested the exemplary achievement standards and assessment standards for the subject of Human Development, Food and Nutrition. Future study needs some critical review for the method of developing achievement and assessment standards for the subject of Human Development, Food and Nutrition. For example. the properness of 'Contents Element' which was designated as the developing field in the achievement standards, the discussion on validity of Contents Element abstract. the base of evaluating classification in terms of low, middle and high level, and other things should be considered through critical discussion. Especially the follow-up study should include the development of various evaluating methods to enable the clear communication for the achievement and assessment standards based on abstract concept and theory, thereby it could enable the actual interpretation and practical use.

The purpose of this thesis is to upgrade brand logo's equity by objective and professional evaluating tool. A brand logo is the main factor in making brand equity, but many times a brand logo is decided without objective judgment because making a logo is considered an intuitive process. To minimize the poor judgment by non-experts, a brand logo needs objective numerical grading tool. Thus, a brand logo is a factor in making a brand identity, not only brand image. That is why brand logo must be chosen by an expert's object judgment. The concrete method to obtain a objective, and at the same time professional grading tool which can De used for the developing and verifying process for a brand logo is as below-first, considering brand judgment from various angles through existing literature, I found various logo grading factors and then extracted them with professional identity designer's subjective consideration. second, applying extracted factors to actual logo grading, verify as a efficient design management tool
