  • The old evidence problem raises a profound problem to Bayesian theory of confirmation that evidence known prior to a hypothesis explaining it cannot give any empirical support to the hypothesis. The old evidence problem has resisted to a lot of trials to solve it. The purpose of the paper is to solve the old evidence problem by showing that the problem originated from a serious misunderstanding about the Bayesian concept of confirmation. First, I shall make a brief analysis of the problem, and examine critically two typical Bayesian strategies to solve it. Second, I shah point out a misunderstanding commonly found among Bayesian discussions about the old evidence problem, the ignorance of the asymmetry of confirmation in the context of explanation and prediction. Lastly, 1 shall suggest two different concepts of confirmations by using the asymmetry and argue that the concept of confirmation presupposed in the old evidence problem is not a genuine Bayesian concept of confirmation.

  • To better publish geographical information on the Web, it is important to capture how Web technologies are changing. For a recent decade, Semantic Web has been developed by incorporating ontologies into the current Web, with an aim to make computers understand rather than simply display. Ontology, an explicit specification of a conceptualization, and the Semantic Web grounded on the ontology, have the potential for effective sharing and appropriate retrieval of geographical information. This paper describes a Semantic Web Service over the mobile Web that can offer pertinent tourism information according to user contexts. To do this, a tourism ontology was formalized in the PARA(Place-Attraction-Resource-Activity) ontology model by organizing tourist places, tourist attractions, tourism resources, and activities. Locational relationships between tourist places were also included in the PARA ontology model to take into account the movements of tourists on a railway network. The XML(Extensible Markup Language) Web Service in the middle tier manages the client-side request for information retrieval and the corresponding server-side response from the data provider. The PARA ontology was integrated into the XML Web Service for the concept-based discovery of tourism information. The applicability of the proposed system was tested through a simulation experiment for Tokyo tourism.

  • Applying the concept and components of human nature to the conversational agent in the smart home context, this study investigated the effects of the level of anthropomorphism and interaction type on the emotional user experiences and future use intention. The results of experiment study showed that the high-low condition of anthropomorphism and the voice-chatting interaction type have impacts on the perceived closeness, likability, and future use intention. That is, people evaluate the conversational agent as more close, likable, and useful when they perceive more human nature components and when in the voice interaction mode. Psychological resistance was lower in the voice than in the chatting mode regardless of the level of anthropomorphism. The results also demonstrated an interaction effect of anthropomorphism and interaction type on the future use intention: the effect of anthropomorphism existed only in the voice interaction mode. It leads to the conclusion that a conversational agent with the voice recognition interface should be designed with the higher level of human nature components for the continuous use.

  • The safe level for residential structures has usually been prescribed as just 'particle velocity' in various specifications in Korea. It implies that there is a possibility of interpreting the 'particle velocity' as the PPV (Peak Particle Velocity), PVS (Peak Vector Sum), or something else, depending on the interpreter. As a result, there have always been some difficulties in both designing a controlled blasting and controling the blast-induced ground vibrations. This paper is intended to show what the role of the safe level criteria such as PPV or PVS is, and also how we should use the concept of the scaled distance equation in a controlled blast design. The paper also emphasizes the importance of the allowable level for various residential structures and its uses in each stage of the controlled blast design.

  • Achieving a certain degree of objectivity is one of main assessment priniciples to meet and self-assessment has been under-used as a formal instrument for assessing students' achievement due to lack of objectivity. Now, this research attempted to look into how students perceived self-assessment and how they engaged in the assessment process. Self-assessments and in-depth interviews with students were collected as main data sources. The results of data analysis are as follows. First, a student' perceptions of self-assessment have been observed to change over a course of a semester. Furthermore, changes in perceptions might have led students to get ownership of their learning. Conclusively, this research proposes that the research of self-assessment be accommodated into the socio-cultural context to demonstrate its desirable influence on students' learning.

  • There are multiple process mechanism in causal reasoning, which is estimation of the causal strength between cause and result. Further, because these mechanisms operate on different time phase during causal reasoning, it is highly possible that different individual difference factors are related to individual mechanisms of causal reasoning. Especially, the phenomena of conditionalization and discounting reflect attention to multiple potential causes when people infer the relationship between cause and effect. In this study, we manipulated self-construal which is an individual difference factor that reflects context sensitivity in cognition. As results, no difference was observed in conditionalization between individuals with an independent self-construal and those with an interdependent self-construal. However, independent self-construal group was observed to be lower in discounting than the interdependent self-construal group. The results indicate that conditionalization and discounting are independent cognitive process in human causal reasoning.

  • Entering the period of Mass Customization, and with the help of the Digital Textile Printing technology, the purpose of this study is to propose two customer involved design process models, based on the Digital Textile Printing technology, and to compare their efficiencies and appropriateness with those of the existing design process model, which would lead us to discover the possibilities of Mass Customized design process. By the result obtained from the survey of 166 females in their twenties and thirties, the second Mass Customized design process model which gave most choices to prosumers was preferred the most, while the existing design process which gave no choice seemed to be preferred the least, and among the design elements of textile, color appeared to be the most significant influential factor in the preference of the clothing by the consumers. In summary, it appeared that every aspect of the society requires a shift in the process of the thought from Mass Production to Mass Customization at this point, and a guideline was made from the Mass Customized design process suggested in this study.

  • This study aims to understand the information needs and behaviors of university members given the societal shifts incited by the fourth industrial revolution as well as the changes in university research and education. We first conducted several in-depth interviews with diverse university members, and then adopted interpretative phenomenological analysis(IPA) to search the university members' information needs and behaviors including the contexts for such needs. The interviewees demonstrated more complex and convergent information needs than traditional information needs. They had very individualized information needs according their particular situations and took integrated problem-solving methods through their personal networks and/or making their own communities. When the interviewees' information needs were not satisfied by libraries, they tended to show low awareness of the libraries.

  • The purpose of this study is to explore the subjective perception of college students' Internet addiction by applying photovoice method, a participatory research method. The subjects of the study were nine university students at G University. The data were analyzed by orientation, photo collection, photo selection, contextualizing and codifying according to the general photo voice research procedure.As a result, 15 sub-categories were derived based on the meaning of Internet addiction, the effects of Internet addiction on life, and how to get out of Internet addiction. The perception of the meaning of Internet addiction was divided into five categories: 'loss of self-regulation', 'habit without exit', 'disconnection from the world', 'loss of me', and 'voluntary prison'. The effects of Internet addiction on life were 5 categories: 'health deterioration', 'social isolation', 'broken daily life', 'anonymous violence' and 'my discovery and life extension'. In terms of how to get out of internet addiction, 'self-looking', 'new hobbies', 'nearby', 'reality meetings', and 'forced blocking' were derived. It suggested the discussion about Internet addiction viewed by college students and the implications of constructing a counseling program that can help to use the Internet correctly.
