The Characteristics of the flowfields of a square prism having a small vertical plate at the upstream side was investigated by measuring of fluid force on the square prism and by visualization of the flow fields using PIV. The experimental parameters were the width ratios(H/B=0.2~0.6) of vertical plates to the prism width and the gap ratios (G/B=0~3) between the prism and the vertical plate. The drag reduction rate of the square prism was increased with H/B in case of the same G/B, and was increased and then decreased with G/B in case of the same H/B. The lift reduction rate of the square prism was hardly not affected by the width and gaps ratios, the average value was about 48.1%. In case of a square prism having a small vertical plate, the stagnation regions were represented in the upstream and downstream sides of the square prism.

Since Goryo was established during the early tenth century, Koreans have believed that Goguryo, which ruled almost all of the Manchurian territory, was one of the Three Kingdoms of their ancestors. This Korean perspective conflicts with the Chinese perspective that Goguryo was a Chinese local government in Manchuria and the northen parts of Korean Peninsula. Modern Chinese people wish, by the measure of Manchurian Project, that the history of China includes the histories of all the ethnic groups in Manchurian territory. Although Chinese people attempt unreasonably to regard Goguryo as an old Chinese local government, it is not from the Korean nationalistic viewpoint but from the scientific historian viewpoint that this Chinese perspective should be criticised and corrected. We should remember that the nationalistic viewpoints in East Asia may hinder the establishment of mutual cooperation and security in the region.

In This Paper, I call Johnson & Lakoff (1980; 1999)'s Experientialism or Experiential Realism or, Embodied Realism, Nunez(1995; 1997)'s Ecological Naturalism as Experientialism and try to investigate the possibility of their Experientialism to be a philosophy of mathematical education. This possibility is approached in the respect with the problem of objectivism and relativism. I analyzed the epistemological background of embodied cognition first and then mathematical epistemology of experientialism. Experientialism shares its Philosophical position partly with Dewey and Merleau-Ponty. Experientialists deny the traditional hypothesis of philosophy as such separability of subject and object, and of body and rationality and also They have better position of epistemology than that of Hamlyn, and of Social Constructivism. Therefore, They guarantee wider range of mathematical universality than Hamlyn and Social constructivist. I conclude that the possibility of Experientialism to be a philosophy of mathematical education depends on the success of its supporting the practical study on mathematics education.

This paper aims to examine the causes and features of current generational conflicts in Korea and to discuss their implications. The data utilized in the study include collective data on presidential and general elections and secondary data obtained from empirical research. The findings are as follows. First, generational power conflicts express itself by struggles among generations concerning the timing of political power transfer. An average age of assemblymen decreases consistently regardless of changes in overriding ideological atmosphere in general - conservative vs. liberal. Second, ideological conflicts among generations were highly intensified around 2002 presidential election, but gradually moderated since 2004 general election. The conflicts might be re-intensified if a set of conditions were satisfied. Third, cultural conflicts between older and younger generations were contrasted around three cultual axes: economic growth with top priority vs. consumerism, collectivism vs. individualism, and authoritarianism vs. post-authoritarianism. To ease strained relations between generations, intergenerational programs were suggested.

This thesis aims to examine the discussions on communitarianism and liberalism, which was actively debated post-1990's in the West. The paper will focus on the concepts of morality and ethics of Hegel's "Philosophy of Law" in order to connect the discussions on communitarianism and liberalism to our society's political reality. Specifically, through the introduction of Hegel's point of view, this paper will shed new light co the concept of communitarianism, which was viewed from the perspective of political philosophy within the West post-1990's. Through "Philosophy of Law," Hegel imbues a critical and fundamental meaning to modern ethical-political order. For Hegel, Kant's acceptance of morality has a foundational and compositional meaning for the concepts of law and nation. This paper will discuss this topic within the boundaries of Hegel's morality and ethics and regard this as a chance to look back on our political situation with a regretful introspection. International and national reviewers tend to regard the various perspectives of Hegel's philosophy of law as inspirational. However, it seems that the fundamental introspection of why our reality must adhere to his philosophy is lacking. Based on this concern, the paper aims to examine Hegel's "Philosophy of Law" to apply his perspectives to our political reality for a fundamental self-evaluation.

This study is purposed to discuss attributes and limitations of neo-liberalism and to offer some roles of Christian education corresponding neoliberalism. Neo-liberalism is an econosuperism that entrusts all things to market order, and it regards this market as utopia. It does not remain as just an economical principle, but influences all aspects in human life. Then it shows its religiosity connecting to capitalism. Every human in it is thought of as flexible workforces appropriate to neo-liberalism market. Such being the case neo-liberalsim strenghtens instrumentation in education. Then it distorts freedom and equality, and it weakens traditional values. Because of this, modern people's identity is getting to be lost and their human characters to be floated. This study discusses these things critically, and offers roles of Christian education such as founding a well balanced understanding on the Scripture against this neo-liberalsim market, restoring the essential purpose of education from instrumentation in education, and investigating and applicating a holistic human character on the basis of a Christian anthropology against this new human character of neo-liberalsim.

The Perfectionism Index (PI) is an indicator that is recently proposed to distinguish influential researchers from mass producers. In this study, Near Perfectionism Index (NPI), an improved indicator of Perfectionism Index, can be a solution to the problem of PI that indiscriminately gives a penalty to all low-cited papers regardless of publishing time or other issues. NPI improved the method to give a penalty to tail complement area considering the citation distribution curve. It prevents the improvement of the h-index from adversely affecting the researcher's influence indicator. This study uses NPI to evaluate information and library science journals in Web of Science database. It successfully distinguishes between influential journals and mass producers unlike journal h-index or average citation frequency which could not differentiate influentials from mass producers.

The purpose of the present study was to develop a convergent education contents for dementia prevention, operating on the web network applying modern information technology(IT). At the preparation stage, local and worldwide literatures related to dementia were analyzed followed by surveying industry demands, based on which the program was designed and developed. In the following enhancement stage, the program was modified as much as possible by advices obtained from experts in various fields. Development results of the present program are summarized as follows. Firstly, 645 intellect development model to prevent dementia was established through peer review and verification of convergent education theories by expert groups. This model was named as "Garisani" meaning "cognition capable of judging objects" in the Korean language. Secondly, 'Find a way' and 'Connect a line' modules were developed in the numeric field as well as 'Identify a letter(I, II)' modules, in the language field for web-based left brain training program. Thirdly, 'Find my car' and 'Vision training' modules in the attention field and 'Object inference' and 'Compare pictures' modules in the cognition field were developed for web-based right brain training program. Fourth, 'Pentomino' and 'BQmaze'(Brain Quotient and maze) modules in the space perception field and 'Visual training' in the memory field were developed for web-based left and right brains training. Fifth, all results were integrated leading to a 52 week Garisani convergent education program for dementia prevention.

The purpose of this study was to investigate the actual situation of nursing students' exposure to blood and body fluids, and their knowledge, awareness and performance of standard precautions in an attempt to offer basic data for education of nursing students concerning infection control. The participants of this study were 309 juniors and seniors enrolled in the nursing colleges in J province. Of the participants, 71.5% turned out to have experienced exposure to the blood and body fluids of patients. The mean score of the knowledge about standard precautions was $20.59{\pm}2.05$, whereas grade, infection control education were statistically significant. The average awareness of standard precautions scored $4.67{\pm}.36$, and age, no follow-up measures were statistically significant. The mean sore for the performance of standard precautions was $4.25{\pm}.70$, while exposure to blood and body fluids was found to be statistically significant. There was positive correlation between the participants' knowledge, awareness and performance. The awareness(${\beta}=.274$) of standard precautions only stood out significantly among the factors affecting the performance of standard precautions, accounting for 8.6% in the performance variance of standard precautions. The study found it necessary to develop the infection control program in diverse ways by complementing especially the areas which used to show low awareness and performance of standard precautions. It is thus suggested to intensify education for students about infection control prior to starting clinical training.

Network technology used as a physical interface to retrieve, store, and exchange data is leading the era of data capitalism in the 21st century. The capacity of network technology dominates almost all communication in everyday life, and makes social understanding and experiences in the physical world visible in cyberspace. The movements of human bodies and objects in cyberspace are placed in a social context. This paper paid attention to these phenomena and examined the cases of activism that raised real problems through cyberspace. In particular, the focus of the study is the digital activism of the Electronic Disturbance Theater, which combines critical art and thinking for democracy with the realm of information and demonstrates aesthetic imagination. The first chapter of the main body briefly outlines the meaning activism as a social movement in cyberspace. The second chapter looks back on the alternatives of <FloodNet>, which represents the early activism performance of EDT. And then in the last chapter, the poetic significance of the <Transborder Immigrant Tool> is analyzed. Through this process, this paper demonstrates that the activism performance of the EDT is a critical aesthetics that encourages imagination for alternatives. It also argues that Electronic Disturbance Theater has contemporary value as an avant-garde art that actively utilizes the medium of network technology and integrates performance art and politics.
