When a product is designed, user's requirements should be well analyzed and applied to the design so that the psychological and aesthetic factors of a product can be accurately conveyed to consumers. The essence of product development is to analyze the changes in the purchasing tendency of consumers and the needs of times, find out user experiences to apply to a design, and establish the objective of product development that well considers those. Designing should be recognized as one that designs even the sensitivity and experience created in the relationship with users, beyond the conventional notion of design that it draws the physical form of a product. As the subjects that design should consider have expanded like this, it has become important that today's design provides a new experience as well as simply develops formative elements based on the functions of an object. As a result, it becomes impossible to accomplish such objective only with the traditional design process that existing designers have stuck to so far. In this respect, this study is aimed to draw out a system and methodology for a user-oriented design process so that design can provide expanded experience to users from product form, applied material, and service.

The explosive growth of wireless network users and the existence of various wireless services have demanded high rate throughput as well as user's QoS guarantees. Towards this, this paper proposes QoS-oriented subcarrier allocation scheme considering the QoS provisioning of multiple users, which is major requirement for wireless network design point of view. This paper introduces joint RR/K&H combined with M-LWDF(Modified Largest Weighted Delay First) scheme throughout observing statistical channel behavior and real time queuing analysis for appropriate resource allocation tightly connected to multiuser scheduling. Accordingly, the system throughput can be enhanced, and the QoS demanded for delay sensitive services can be satisfied. Furthermore, the proposed scheme is applied for OFDMA(Orthogonal Frequency Division Multiple Access) systems to allocate sub-carriers in optimal way. The simulation results verify plausible performances of proposed resource allocation scheme via showing superior effective capacity under time-varying physical-layer channel behaviors.

Consumers have come to demand high quality, affordable prices, and innovative product designs of the outdoor wear market due to their well-being and leisure oriented lifestyle. A new system of business in outdoor wear has emerged in the process through which corporations have endeavored to satisfy such consumer needs. Outdoor wear brands have utilized social network services (SNS) such as Facebook and Twitter as means of marketing and have built close relations with consumers based on communication through these media. Recently, explosively escalating SNS data are referred to as social big data, and now that every consumer online is a commentator, reviewer, and publisher, the outdoor wear market and all of its brands have to stop talking and start listening to how they are perceived. Therefore, this study employs Social $Metrics^{TM}$, a social big data analysis solution by Daumsoft, Inc., to verify changes in the allusions related to outdoor wear market found on SNS. This study aims to identify changes in consumer perceptions of outdoor wear based on changes in outdoor wear search words and trends in positive and negative public opinion found in SNS social big data. In addition, products of interest, the major brands mentioned, the attributes taken into consideration during purchases of products, and consumers' psychology were categorized and analyzed by means of keywords related to outdoor wear brands found on SNS. The results of this study will provide fundamental resources for outdoor wear brands' market entry and brand strategy implementation in the future.

Operating Systems is a discipline which handles complex and abstract concepts related to its components and the principles of how an operating system works. However, most of the OS courses have been textbook-oriented theoretical classes. For students who are familiar with various kinds of media, theoretical classes lead to a decline in the understanding of a lecture and difficulty concentrating. They have tried to make use of educational tools to help students understand a lecture and arouse their interests consistently. This paper describes the design and implementation of a disk scheduling simulator which shows the service processes of disk I/O requests visually. The disk scheduling simulator can be used for demonstrations of the disk scheduling algorithms. The results of the academic achievement evaluation and survey showed that a disk scheduling simulator is useful as an educational tool which causes the interests about operating systems and enhances the understanding of a lecture.

This study discusses an equity analysis performed to supplement the existing bus service evaluation system. The equity of 179 feeder bus routes in the city of Seoul(Year 2009) is analyzed by employing the modified BCC model along with the desirable inputs such as a number of bus stops and a frequency of operations. In the analysis, each DMU (Decision Making Unit) is assumed to use the desirable inputs, and produces both the index of equity and the index of accessibility. We apply an input-oriented modified BCC model to analyze the equity of the DMUs. The computational result indicates that only 9% of the feeder bus routes are equitable among the total DMUs and the average equity estimate is 0.702. It is also suggested that on average approximately 60% increases of desirable inputs (i.e., a number of bus stops and a frequency of operations) are needed in order to improve equity of DMU in the city of Seoul. The result of the tobit regression analysis on the determinant factors affecting the equity of DMUs shows that all the independent variables (i.e., a number of bus stops and a frequency of operations) are statistically significant at 5% significance level, and the number of bus stops is found to be the most influential factor.

Video information is an important component of multimedia systems such as Digital Library, World-Wide Web (WWW), and Video-On-Demand (VOD) service system. Video information has hierarchical document structure inherently, so it is named "structure video document" in this paper. This paper proposes a data model, a query language, and an indexing scheme for structured video documents in order to store, retrieve, and share video documents efficiently. In representing structured video documents, the object-oriented data modeling technique is used since the hierarchical structure information can be modeled as complex objects. We also define object types for the structure information. Our query language supports not only content-based retrieval, which means the queries based on the structure of video documents, and spatial/temporal relation for video documents. In order to perform structure queries efficiently, as well as to reduce the storage overhead of indices, an optimized inverted index structure is proposed.

Purpose: This research was conducted to explore the experience of middle-aged women parting with their children and to develop a grounded theory. Method: The participants were 11 women in their 50's who had experienced parting with their children due to schooling, military service and marriage. The grounded theory methodology based on symbolic interactionism was used. Results: 106 concepts, 30 subcategories and 14 categories were derived from the analysis through processes of open coding, axial coding and selective coding. The central phenomenon was 'happy but sad' and the core category was a process of 'independence that is sorrowful yet delightful'. Four types were identified; the independent-type; submissive -type; family-reliant-type ; and fragile-type; based on the attachment to the child, state of mind, satisfaction of the situation, family support system and self-achievement. Conclusion: This research identified that the modern Korean middle-aged women who are considered to be the 'sandwich generation' since they have experienced a turbulent history and the change from a confucian parent-child lifestyle to a couple-oriented one, moved away from an attitude dependent on children in parting with them and started preparing for an independent late life. Based on the results, the verification research is advised on the variables that affect the experience of parting with children.

This study focuses on systematic structure of factors, which affect commercialization of ocean science and technology (OST), applying both grounded theory methodology (GTM) and semantic network analysis methodology (SNAM) by using in-depth interviews with 8 specialists previously experienced in the same field. This study further focuses on clarification of the distinctiveness and universality of commercialization factors on OST by comparatively analyzing on the commercialization factors of general sciences and technologies. Using SNAM, it was determined that commercialization success required connected support system, government support, technology marketing, technology power and characteristics of commercialized entities, which were identified as dominant factors. GTM presented an outcome that connected support systems among participants in commercialization and found that research institute strategies are significant factors in the core phenomenon of commercialization, while technology marketing, technology power and market-oriented technology are important conditions. In addition, the factors of technology, market, connection of participants and government support of commercialized entities are shown as equally important factors for commercialization of ocean science and technology. Secondly, SNAM results indicate that ocean science characteristics depend on a network of government support, research institute strategy, organization and manpower, capital power, and technology marketing, as these ocean science characteristics have been identified as significant factors in the GTM study. It has been determined that technology, market and government support should be connected in order for commercialization of ocean science and technology (OST). Moreover, commercialization methods, applied to the marketing of commercialization of ocean science and technology is differentiated from others since commercialization success is more relevant to these factors.
