Much information has been hierarchically organized to facilitate information browsing, retrieval, and dissemination. In practice, much information may be entered at any time, but only a small subset of the information may be classified into some categories in a hierarchy. Therefore, achieving document filtering (DF) in the course of document classification (DC) is an essential basis to develop an information center, which classifies suitable documents into suitable categories, reducing information overload while facilitating information sharing. In this paper, we present a technique ICenter, which conducts DF and DC by recognizing the context of discussion (COD) of each document and category. Experiments on real-world data show that, through COD recognition, the performance of ICenter is significantly better. The results are of theoretical and practical significance. ICenter may server as an essential basis to develop an information center for a user community, which shares and organizes a hierarchy of textual information.

분수 나눗셈 알고리즘에 대한 학생들의 어려움 중 상당부분은 현행 교과서의 알고리즘 유도방법 자체에 기인한 것으로 보인다. 본 연구에서는 분수 나눗셈 알고리즘을 유도하는 대안적 방법들 중 단위비율 결정 맥락의 교육적 가치를 분석하고 학생들에 대한 설문과 면담을 통해 그 실제 도입의 가능성을 확인하였다. 또한 이 결과를 바탕으로 분수 나눗셈의 지도 방법 및 교육과정 구성에 대한 대안적 방법을 제안하였다.

This study explored the theoretical context of postmodern aesthetics in experiencing art/craft/handmade/studio furniture for 'wood culture experience class' or 'wood love experience class', which has been recently carried out by the Korea Forest Service and is apt to focus on making simple wood work just involved in the practical part. Qualitative conceptual analysis as the principal methodology was used to achieve the theoretical context in the experience programs. I developed the lesson for an aesthetics of art and everyday life with wood furniture which expresses the metaphorical aesthetics appeared as New Design furniture in postmodernism. As statement of objective in the lesson, I explored that students in elementary schools personally understand and define the postmodern aesthetics of New Design furniture as metaphor. As a result, the students will be able to define and identify New Design furniture as metaphor in their lives.

Purpose The purpose of this study is to explain the mechanism of user behaviors in password reset context based on descriptive data from conducting interviews. Specifically, this study attempted to describe the process of changing password from the shadow work perspective. Design/methodology/approach This study has interviewed 8 participants who can freely use numerous online web-sites. This study also employed the grounded theory methodology to analyze interview manuscripts. After conducting analyzing the manuscripts, this study has extracted 46 codes in the coding steps and ultimately presented 8 categories by combining similar concepts from those codes. Findings According to the results, this study provides new viewpoints to explain unique user behavior in the password reset context by capturing the shadow work based on the results. This study further offers practical implications to numerous practitioners by finding various codes, which related to users' reaction and behavior.

As an increasing number of people gained access to social network services (SNS), organizations started to use SNS as a channel for marketing and promotional purposes. The online advertising market has significant growth potential. Brand engagement is a key motive for online advertising, but how SNS users engage with brands, particularly in terms of the promotion of organizations, is poorly understood. This study uses customer value theory to examine brand engagement of users in terms of promoting companies in the context of Korean SNS marketing. This study identifies the antecedents of brand engagement based on customer value theory. Our findings show the significance of three factors of SNS marketing, namely, price discount, relationship support, and convenience, on brand engagement. We further show the consequences of brand engagement, namely, purchase decisions and word-of-mouth activities. These findings help advance customer value theory and offer practical insights into the use of information systems and marketing in the context of SNS.

This study investigates the influences of the head movement (nodding vs. head shaking vs. nothing) on consumer attitude and purchase intention toward the product in an online shopping context and introduces the consumer motivation (need vs. want) as a moderating factor for this relationship. Through two studies, this article finds that nodding, as opposed to head shaking or no movement, leads to more positive attitudes and higher purchase intentions toward the product, and this effect is strengthened when the shopping is pursued with a need compared to a want motivation. The effect is found specifically in the fashion industry, where online shopping is most prevalent. Both theoretical and practical implications are discussed.

The study undertakes an examination of nutrition labelling system and offers a strategic framework for improvement of the system in Korean context. Thus this study includes a review of Korean current nutrition labelling system (NLS), development of a strategy or a further study for its revision of NLS, and a suggestion of revised nutrition labelling guidelines. Participants were 600 university students in Busan and were asked to fill in a questionnaire. The data collected were processed with the SPSS statistical program to produce its frequency, percentage, average, and standard deviation with One-Way Anova and Duncan Test. The findings are as follows: the levels of consumer's practical use and awareness of NLS are low, the levels of their trust and satisfaction and their necessity for NLS are low too. Consequently, the consumer's attitudes to NLS are not related to nutrition labelling method(? system).

Under the WTO, UIA asks professional degree programs such as B.Arch program, practical experience, and an examination to meet the international requirements. In this context, we are started professional degree programs. Following the foundation of KAAB, Korean architectural education sectors have made substantial changes throughout the nation. There was lots of discussions about education system, however, we are lack of discussing about internship program in Korea. Therefore, this research was intended to review the professional practice program in other countries for the purpose of propose our education program. The specific content deals with various issues, like CPD and foreign architect legislations, and the recent korean legislation reform of 'Architect Law' centered upon Professional Training System. The aim is to identify the examples of forms and contents regarding the execution of new Professional Training System in current conditions.

Company A, an embedded system manufacturer, has been managing multiple development projects. Executives need to understand the risk level of every project and prioritize resource distribution. Traditional project monitoring tools or excel sheets are too complex for calculating the risk factors across a functional organization. Two new charts, "Spear-head Chart" and "Float Chart" were designed to assist high level decision making processes. Two charts were used for weekly executive meetings in order to monitor project progress and rectify project direction. One page graphical monitoring tools in Company A are good enough for high management decision making. Authors explain the characteristics of two charts and propose its practical implementation in real working environment. Spear-head chart was also implemented as a system.

In the oral cavity, complex microbial community is shaped by various host and environmental factors. Extensive literature describing the oral microbiome in the context of oral health and disease is available. Advances in DNA sequencing technologies and data analysis have drastically improved the analysis of the oral microbiome. For microbiome study, bacterial 16S ribosomal RNA gene amplification and sequencing is often employed owing to the cost-effective and fast nature of the method. In this review, practical considerations for performing a microbiome study, including experimental design, molecular analysis technology, and general data analysis, will be discussed.
