The purpose of this study is to analyse the ethical basis of two influential global citizenship idea - Rawls' liberal approach and cosmopolitan republicanism - as a theory on global justice. In the aspect of deontology, Rawls' view has the limit not to reflect reciprocal obligation and duty on civil right in the era of economic globalization that inequality has been structured. But cosmopolitan republicanism has the basis of deontological justification because advocates the realization of anti-domination principle at global level. In the aspect of utilitarianism, Rawls attempts to justify the logic rejecting redistribution intra nations. But cosmopolitan republicanism has the potential to decrease maleficence at global level and to increase utility level through overcoming the structured sacrifice of the citizens of developing countries.

Recently, service-oriented systems have been issued by their properties of reducing software development time and effort by reusing functional service units. The reusability of services can effectively promote through loose coupling between services and loose coupling between services depends on component-based system. That is, the component-based system is designed by grouping the tightly coupled classes of the object-oriented system and the service-oriented system is designed by the component-based system. Therefore, to design the component-based system and service-oriented system efficiently, a metric to measure the coupling between classes accurately needs. In this paper, we propose a coupling metric between classes applying a structural property, a dynamic property, and the normalized value by 0-1. We prove the theoretical soundness of the proposed metric by the axioms of briand et al, and suggest the accuracy and practicality through a case study. We suggest the evaluation results of the proposed metric through a comparison with the conventional metrics.

Actually a diffusion of a semantic web application and utilization are situations insufficient extremely. Technology most important in semantic web application is construction of the ontology which contents itself with characteristics of semantic web. Proposed a suitable a method of building web ontology for characteristics or semantic web and web ontology as we compared the existing ontology construction ana ontology construction techniques proposed for web ontology construction, and we analyzed. And modeling old ontology to bases to description logic and the any axiom rule that used an expression way of SWRL, and established inference-based web ontology according to proposed ways. Verified performance of ontology established through ontology inference experiment. Also established an web ontology-based intelligence image retrieval system, to experiment systems for performance evaluation of established web ontology, and present an example of implementation of a semantic web application and utilization. Demonstrated excellence of a semantic web application to be based on ontology through inference experiment of an experiment system.

The introduction of real numbers is one of the most difficult steps in the teaching of school mathematics since the mathematical justification of the extension from rational to real numbers requires the completeness property. The author elucidated what questions about real numbers can be unanswered as the "institutional didactic void" in school mathematics defining real numbers as the union of the rational and irrational numbers. The pre-service teachers' explanations on the extension from rational to real numbers and the raison d'$\hat{e}$tre of arbitrary non-recurring decimals showed the superficial and fragmentary understanding of real numbers. Connecting school mathematics to university mathematics via the didactic void, the author discussed how pre-service teachers could break the illusion of transparency about the real number.

The purpose of this study is to review the role of dragging in dynamic geometry environments. Dragging is a kind of dynamic representations that dynamically change geometric figures and enable to search invariances of figures and relationships among them. In this study dragging in dynamic geometry environments is divided by three perspectives: dynamic representations, instrumented actions, and affordance. Following this review, six conclusions are suggested for future research and for teaching and learning geometry in school geometry as well: students' epistemological change of basic geometry concepts by dragging, the possibilities to converting paper-and-pencil geometry into experimental mathematics, the role of dragging between conjecturing and proving, geometry learning process according to the instrumental genesis perspective, patterns of communication or discourse generated by dragging, and the role of measuring function as an affordance of DGS.

Humanities is one of the largest buzzword in Korea. Humanities programs are being provided indiscriminately in public authorities, universities, life-long education institutions, cultural centers, the media, museums, libraries etc. Among them, the public library is the base camp for spreading and popularizing the humanities. Nevertheless, there is also a critical views for the humanities program of public library. The purpose of this study is to discuss the discourse of the humanities banquet in theoretical positions and practical aspects. The former discussed the humanities banquet in terms of academic axioms, global macro and micro discourse, social and economic wave, the spirit cultural evolution. The latter discussed the humanities banquet at the axiom and identity of the library and humanities, pitfalls and limitations in terms of reason, paradox and the dilemma on the linkage side, inconvenient truth at the destination aspect, weaknesses and challenges in the content aspect.

Null steering and beam steering are known well as anti-jamming methods in GPS anti-jamming system. Null steering gets a noise attenuation effect for the direction of jamming and beam steering earns additional gain synthesis for the direction of satellite signals. According to the research in the article for signal processing, it expresses that the N array antenna is effective for N-1 number of jamming signal by math public interest, however, the two algorithms analysis is not unknown for the operating condition of the realistic vehicle. In this paper, we modeled anti-jamming system using 4 and 7 array antenna and showed the two algorithms performance (PM, LCMV) when considering the number of antenna array, jammers and vehicle position (horizontal, vertical). In result, we showed that the case of vertical position of the vehicle which has large tilt angle for the relative position of satellites and jammers, has about 10 dB gain more in comparison with one of vertical position in spite of same JSR condition.

This paper analyzes the effects of national culture on an individual's ethical decision-making in the context of the Internet. An ethical decision-making model which posits that five moral philosophy variables-justice, relativism, egoism, utilitarianism, and deontology-affect ethical judgment; ethical judgment, in turn, affects behavioral intention was proposed and Hofstede's five cultural dimensions of power distance, individualism, masculinity, uncertainty avoidance, and long-term orientation were used to analyze the effects of national culture on the model. The results showed that power distance, individualism, and masculinity had significant effects on the relationship between the deontology variable and ethical judgment, individualism, masculinity, and uncertainty avoidance had significant effects on the relationship between the justice variable and ethical judgment, and individualism and long-term orientation had significant effects on the relationship between ethical judgment and behavioral intention in the Internet context.

This study is to re-read Yun, Baek-nam(1888-1954)'s editorial "Theatre and Society" from the perspective of postcolonial criticism. He was a man of the theatre who pursued practical interests in compliance with the colonial reality under the rule of the Japanese imperialism. His advocacy of theatre development work was based on the Japan-directional reformism and on Japan-friendly in following after Japan's improvement policy. His general discussion on Western theatre history had considerable errors as a result of focus on the social role and utility of the theatre. But his vindication of theatre-actor opened an era of interaction between theatre and intelligence in Korea. In addition, his enlightening view of a theatre became such as one of the cornerstones for the Shinkug Movement during Japanese colonial period in Korea.

This study was designed to identify nursing students' attitudes toward life through a Q-methodology. A Q-sample was formed through a review of the literature and interviews(n＝160)l The final Q-sample consisted of 37 statements out of an initial 100 statements after consultation with an expert panel and pilot testing. The P-sample consisted of 14 university nursing students and 27 junior college nursing students, which was selected by convenience sampling method. Data were analyzed by the Q-analysis method. The correlation between type 2 and type 3 was relatively high (r＝0.539) ; that between type 1 and type 3 was lowest (r＝0.014). The first type of attitude was the “rational utilitarian” type. Students in this type valued life relative to the quality of life. They agreed with euthanasia and artificial abortion if the quality of life was threatened. The criteria for their judgement were scientific knowledge and rationality. The second type of attitude was the “Christian deontologic” type. These students appreciated the sanctity of life according to Christian dogma. They disagreed with euthanasia and artficial abortion. And they disagreed strongly that life should be created by scientific development, because only God creates life. The third type of attitude was the “unconditional deontologic” type. These students agreed with the sanctity of life, not from Christian belief but from belief in the sanctity of life. The final type of attitude was the “prima facie(conditional) deonologic” type. These students appreciated the value of life and humanity. They expressed concern for others' life and suffering. They do not want to afflict others with their own miseries. This group showed a dual value system toward themselves and others. So they experience conflict between their concern for their on and others' conditions. These nursing students' values may have been influenced by their clinical experience in hospitals and other nursing fields. Through this study, we may realize the importance of education in nursing ethics for discussion of ethical conflicts and to support ethical nursing practice.
