Launched by Samsung in 2003, nano-silver washing machines were a representative application of nanotechnology in commercial products until the US Environment Protection Agency (EPA) decided to regulate companies that produce nano-silver products in 2006. A year later, however, the EPA reclassified the washing machines not as an application of nanotechnology but as an ion-generating machine. As shown by the EPA's equivocation on this issue, establishing a category for nano-silver material should be considered in the procedure of risk assessment and regulation. This paper analyzes the controversy over Samsung's nano-silver washing machines more in detail to study how the demarcation between silver ion and nano-silver can vary according to the risk perception of nanotechnology. In Korea and the US, the boundary between silver ion and nano-silver was malleable and mobilzed depending on the contexts. Based on an analysis of the recent history of nano-silver washing machines, this paper explores the influence of risk perception over the ontological perspectives on a certain material.

It's a matter of ontology rather than that of cognition and methodology to discuss a work of art in Gadamer's philosophy. In addition, he emphasizes the cognitive aspect of a work of art instead of comparing forms and contents of them. For that reason, he excludes aesthetic consciousness derived from Kant first and then makes away with Schiller's theory of aesthetic education. For Gadamer, the concept of truth does not mean accord or correspondence. It would rather be an encounter. This encounter is not axed on a specific time, but a continuous and historical one. Basically. a work of art guarantees this kind of an encounter. This encounter is not based on mutual agreement through an objective standard but on recognition with mutual understanding. Therefore, prejudice or tradition should be acknowledged and respected instead of being excluded. We have only to minimize difference between them through conversation. Gadamer's ontology of a work of art is based on such a ground. The function of a work of art is not only simple satisfaction of aesthetic senses but an object of interpretation, that is, a text by presenting a ground of truth through an agreement of situation. This text reveals its meaning in the situation of author-text-reader. The appearance of this meaning is nothing but the birth of truth. Symbol-allegory and classicism show how to express this kind of truth in a work of art. It is true that Gadamer's philosophical hermeneutics cannot be easily applied to interpret a concrete work of art because it just lays emphasis on the process of 'understanding' instead of a detailed analysis on an individual work. For that reason, he was criticized by some people because of this subjectivity of understanding. However, it's meaning could be changed according to the viewpoint on a work of art. There appears various structural approaches on a work of art in contemporary theory of art. Gadamer just asks the basis of such approaches instead of criticizing a specific one Therefore, a practical approach on individual work should be made separately and hermeneutics enriches the meaning of open-ending of each work of art.

Disaster sign data is confirmed data by the experts to the collected data from web and users. In this paper, we focused to make the risk scores to the data based on ontology technology. To analyse the data, first of all, we defined the ontological structure for 4 kinds of disaster types which consists of the bridges, workplaces, buildings, and walls. Base on the ontologies, collected the accidents examples, and then extract the risk rules from the examples. The rules are adjusted with frequencies and weights, and managed to the ontology DB. The rules apply to the disaster sign data, and then calculates the risk scores. It plays role of the index to the risk rates. The disaster sign data management system was implemented and the rules were verified to the system. Because the quality of the risk scores to the disaster sign data depends on the data of the accidents examples's qualities, we assure that the system's performance will be monotonic increasing following up the data upgrades. Continuously, data management is needed. Also the quality control of the rules are needed.

In this paper, a ontology-based keyword structuring method is proposed to represent the knowledge structure of scholarly documents and to make inferences from the semantic relationships holding among them. The characteristics of thesaurus as a knowledge organization system(KOS) for subject heading is critically reviewed from the information retrieval point of view. The domain concepts are identified and classified by analysis of the information activities occurring in a general research process based on scholarly sensemaking model. The ontological structure of keyword set is defined in terms of the semantic relationship of the canonical concepts which constitute scholarly documents such as journal articles. As a result, each ontologically structured keyword set of a document represents the knowledge structure of the corresponding document as semantic index. By means of the axioms and inference rules defined for information needs, users can efficiently explore the scholarly communication network built on the semantic relationship among documents in an analytic way based on the scholarly sensemaking model in oder to efficiently retrieve the relevant information for problem solving.

In researching the ontological status of fashion, a good grasp of fashion can decide the direction of fashion study. Fashion is sometimes considered an area of industry far from art from a point of view of purity of art, in spite of its aesthetic value and expression. However, art properties can be differentiated from the purity of art in modern aesthetics, and fashion properties which were the reason for that fashion to be considered as non-art can be affirmed as the same with properties of contemporary art properties. Therefore, the purpose of this study was to suggest the possibility that general properties of fashion can be accepted in the art arena through justifying art properties deviating from the purity of art. It can provide a boost to fashion's cultural status. For the research method, a literature review and case analysis were carried out through specialty publications related to art history, aesthetics, and fashion, regular publications and websites specializing in fashion, and art museums. Through the research, art properties deviated from the purity of art, which are; tactile sense, impermanence, dailiness, and commercial viability, were justified as being the same as fashion properties. These art properties were not general properties of fine art in modern aesthetics, but the ones occurring in contemporary arts. These properties, now present in contemporary art, can no longer disqualify fashion as a non-art.

This study analyzed the level of chemistry teachers' cognition related to two types of acid-base models taught in secondary schools. For the purpose, a questionnaire was developed to identify teachers' cognitions based on previous studies that analyzed the 'Ignorance' of each model. The questionnaire consisted of two items, one related to acid and base reactions and one related to acid and base dissociation, which suggested inconsistencies between the two models. The subjects were 15 chemistry teachers, and as a result, teachers' cognitions were analyzed at four levels. The four levels are: if they don't know the two models, if they only understand one model, if they understand the two models, and perceived the 'Ignorance' of one model, and if they understand the two models and perceived the 'Ignorance' of the two models. The largest proportion of teachers understood the two models and perceived the 'Ignorance' of one model. However, the proportion of understanding the two models and perceiving the 'Ignorance' of the two models was very small. Through this, we argued that efforts to increase the level of chemistry teachers' cognition of the model and 'Ignorance' were necessary.

The recently many corporations are using Decision Support System, such as on-line meetings. Those on-line meetings are getting grown .Because the on-line meetings with messenger and chatting are the best examples for overcoming space But, the on-line meetings have unavoidable weak points. The more a meeting is processed, the more point of argument is out of focus and perception of current situation is reduced. Therefore, this thesis proposes and describe that in think that pre-defined things , analysis and direction of Ontology ,then draw up a plan how to make ontology to knowledge, and, how to get out of bounds limitation that as make ontology to knowledge. And, design and implementation actual system that organize this ontological Knowledge, and then managing and summarizing visualizing them. Last after remark and consider this system in which using the ontology based on XML, and proposes conclusion and directional development point.

The purpose of this study is to review the trend in comparative education research related to curriculum published in the Korean Journal of Comparative Education, and to critically analyze its characteristics from the postcolonial perspectives. In this study, I analyzed 61 articles published in this journal from 1995 to 2016. The result showed that comparative studies related to curriculum were conducted mainly by benchmarking policies or contents related to curriculum and textbooks of Western countries including North America and Europe as well as Japan which colonized Korea. In addition, although Korea has been changing into multicultural society, studies on Asian countries such as China and Vietnam which are the nationalities of many foreigners living in Korea were rare. Based on the results, this study suggested that the expansion of comparative education research subjects, overcoming of coloniality in comparative education, and ontological reflection of comparative education researchers are necessary.

The purpose of this study is to determine social values of self-support enterprises, known as the origin of social economy by using a qualitative research method. Main themes representing social values of self-support enterprises were developed through four sessions of FGI and thematic analysis. First, self-support enterprises embody the value of 'social safety net' by providing workfare for disadvantaged people as well as by operating market-oriented business. Additionally, 'communal spirit', for which self-support enterprises strive, is social value that enables the entirety of self-support enterprises and participants to fulfill non-profit values, reciprocity, and sharing. Lastly, ontological, diachronic, and ecological 'sustainability' of self-support enterprises is a foundational element which creates continuous positive impact on our society. Findings of this study are significant to provide theoretical and empirical evidence for preservation and development of the social economy ecosystem. Based on this, further researches on comprehensive social economy are suggested.

This study aims to derive the implications of actor-network theory in science education research. To this end, previous studies applying the actor-network theory were analyzed. The study results show that educational research using actor-network theory can be divided into three main approaches. First, ANT was used as an epistemological perspective to construct an educational method or perspective, Second, ANT was used as an ontological perspective to recognize non-human agency, Third, ANT was used as a methodology for educational research. Based on the results, the possibility of contributing to science education research is discussed. As a new theoretical point of view, we hope that actor-network theory will be meaningful in science education practice and empirical research.
