  • According to the expansion of smartphone penetration and development of wearable device, personal context information can be easily collected. To use this information, the context aware recommender system has been actively studied. The key issue in this field is how to deal with the context information, as users are influenced by different contexts while rating items. But measuring the similarity among contexts is not a trivial task. To solve this problem, we propose context aware post-filtering to apply the context compensation. To be specific, we calculate the compensation for different context information by measuring their average. After reflecting the compensation of the rating data, the mechanism recommends the items to the user. Based on the item recommendation list, we recover the rating score considering the context information. To verify the effectiveness of the proposed method, we use the real movie rating dataset. Experimental evaluation shows that our proposed method outperforms several state-of-the-art approaches.

  • In ubiquitous environment, information retrieval using collaborative filtering is a popular technique for reducing information overload. Collaborative filtering systems can produce personal recommendations by computing the similarity between your preference and the one of other people. We integrate the collaboration filtering method and context-aware information retrieval method. The proposed method enables to find some relevant information to specific user's contexts. It aims to makes more effective information retrieval to the users. The proposed method is conceptually comprised of two main tasks. The first task is to tag context tags by automatic tagging technique. The second task is to recommend items for each user's contexts integrating collaborative filtering and information retrieval. We describe a new integration method algorithm and then present a u-commerce application prototype.

  • The purpose of this paper is to carry out an empirical analysis of the link that exists between microfinance and poverty alleviation. The analysis is driven by literature searches on empirical works done by different researchers in different contexts. Qualitative research methodology was adopted, following a desktop approach. An empirical literature review took a centre stage in this investigation. An analysis of empirical works shows that microfinance enhances poverty alleviation despite the challenges such as the Indian Andhra Pradesh crisis. The paper is limited to a review of empirical sources of literature. A field survey, supported by an econometric analysis would have helped to generate robust results. This paper attempts to bring together the empirical works that were done in different contexts to shed light on the important relationship between microfinance and poverty. Many research works on microfinance depend upon personal anecdotes, thus this present paper attempts to compile the scattered empirical findings on microfinance and poverty alleviation.

  • The purpose of this study was to analyze inquiry activities in the middle school science textbooks focused on the unit 'Nutrition of Plants' of the 2007 revision curriculum and the corresponding unit 'The Structure and Function of Plants' of the 7th curriculum in terms of content, process and contexts of inquiries. The average number of the inquiry activities in the unit 'Nutrition of Plants' was 9.2, which was a 3.8 decrease than in the unit 'Structure and Function of Plants'. In the respective of process of the inquiry activities, 'observation' was most prevailing in the basic inquiry process and 'data interpretation' was most prevailing in the integrated inquiry process in both of the units. In the respective of the types and contexts of the inquiry activities, 'experiment/observation' was most prevailing and the percentage of the natural scientific contexts was larger in both of the units. In the unit 'Nutrition of Plants', the components of the integrated inquiry process and the percentage of personal contexts were larger than in the unit 'Structure and Function of Plants'. And simulation activities were newly presented and technical contexts and natural environmental contexts were included in the unit 'Nutrition of Plants'. This study makes a suggestion that a wider variety of inquiry activities should be included when new science textbooks are developed.

  • The purpose of this study is to see how Korean American people use and negotiate appearance in the US. 22 Korean American women at the age of 20s to 50s were interviewed and the verbatim texts from the interviews were interpreted. Discourses on appearance style followed by consumer stories such as American vs. Korean culture, gender, class, generation as well as personal background were recorded. The results of this study revealed that Korean Americans had diverse interpretations about their appearance and styling to fit the condition of their everyday lives. Korean immigrants did not simply assimilate dominant culture over time but maintained transcultural identities depending on contexts. This study showed that researches dealing with cultural variables could have more insights about personal experiences and social meaning processes through interpretative approach.

  • A commitment to physical activity is necessary for personal health, and is a primary goal of physical activity practitioners. Effective practitioners rely on theory and research as a guide to best practices. Thus, sound theory, which is both practical and parsimonious, is a key to effective practice. The purpose of this paper is to review the literature in search of such a theory - one that applies to and explains commitment to physical activity in the form of sport and exercise for youths and adults. The Sport Commitment Model has been commonly used to study commitment to sport and has more recently been applied to the exercise context. In this paper, research using the Sport Commitment Model is reviewed relative to its utility in both the sport and exercise contexts. Through this process, the relevance of the Investment Model for study of physical activity commitment emerged, and a more parsimonious framework for studying of commitment to physical activity is suggested. Lastly, links between the models of commitment and individuals' participation motives in physical activity are suggested and practical implications forwarded.

  • Ubiquitous computing is a study area explained in a myriad of contexts and technological terms. Payment, however, refers in nature to an act of money transfer from one entity to another, and it is obvious that a payment method will be valued as long as the transaction can be completed with safety no matter what technology was used. The key to U-payment is convenience and security in the transfer of financial information. The purpose of this paper is to find a desirable U-payment scheme by looking at the characteristics of seamlessness under the ubiquitous environments, strong personal device, and peer-based information transactions. We also propose U-SDT Protocol integrating technologies such as Radio Frequency Identification (RFID), Bluetooth, Personal Payment Device, Account Managing Application and Transaction ID as a way to make transactions between users seamless and secure better privacy protection.

  • Organizational humor is generally perceived as a phenomenon that helps to develop happy feelings and positive workspace. While humor may affect organizational members in diverse ways, the ambiguous nature of humor may create uncertainty and unexpected outcomes. In particular, humor used by and between organizational members in diverse organizational situations (including physical office context and work hours) may influence individual's perception of space. Findings suggest that humor interaction acts as a form of deviant behavior that diverts from work. This momentary non-work event (humor) may serve as a ritual to influence individual's perception of space, from work to personal domain, and vice versa. The quality of interpersonal relationships between the communicators may also be influenced by humor. This shift in the nature of interaction (from work to non-work) may lead to blurring boundaries of work and work experiences. Therefore, organizational humor may provide insights into how workers interact, perceive, and manage work and personal space within organizational contexts.

  • Within a framework of sociocultural approaches to writing process, this study examined six ESL graduate students' writing processes in depth based on individual interviews and their narratives of writing process. The narratives and interviews were analyzed to discover salient aspects of the students' writing processes and to understand the socially situated nature of the writing processes. First, it was observed that these six students displayed multiplicity in terms of their representations of writing process, episodes, textual practices, and concerns. Several factors including the writing task, students' familiarity with genre, literacy skills, attitude toward writing, and involvement in interaction contributed to individualized trajectories of writing process. It was also revealed that writing is unavoidably a socially situated practice. Students were situated in their cultural arenas as well as their disciplinary arenas, and these contexts helped the students serve as active agents producing and sharing knowledge. The confluence of personal, cognitive, and social factors observed in their writing processes suggests that writing process should be understood from multiple perspectives.
