Industrial design aiming the mutual benefit of both user and manufacturer demands grasping and analyzing the needs and wants of consumer for the establishment of the optimum plan and production by attribute oriented approach. Inspite of its usefulness, however, it might be impossible to help industrial designers to develop a new product effectively without full understanding of industrial design activity in attributes of products and using the appropriate methodology for grasping the major attributes. This thesis is purposed for developing the guideline of research models of consumer for industrial by studying characteristics of industrial design activity in attributes of products through bibliography and defining the clear limit of design research focused on consumer selection through comparison with real purchase decision making procedure at every phase. Through the observation and analysis of the real purchase decision making procedure following the proposed guideline, the possibility of difference between the two cases has been shown in both theoretical and practical aspects.

The present research integrates the core aspects of anger with the theory of planned behavior to investigate factors influencing online activism in a Web site. This study conducted online survey, and the sample was members who joined the V4400 Sobi-ja-heem Web site. The Web site Sobi-ja-heem was initiated by a consumer who was irritated at the cell phone manufacturer Samsung Inc. because its model, "Anycall" had major product defects such as the malfunction of the camcorder, poor tone quality, fuzziness of the screen, and broken text messages. The findings suggests that adding anger in Theory of Planned Behavior (TPB) enhances the explanatory power of the theory in predicting an intention to participate in activities to correct the issue, which indicates the possibility of combining emotion and the TPB in the prediction of online activism.

There are approximately 250,000 organic livestock farming in the world. The total retail value of organic food sales in the world is $ 27 billion. The organic livestock products such as milk, lamb and beef are marketed mostly in Europe and the USA. The market share of organic food is about 2% in total food marketing value of worldwide and of the organic food marketing value, organic livestock products portioned 17% in the USA. The organic livestock products are primarily marketed at Supermarket(Europe), Health and Natural Food store(USA). Concerning international trade, it is very little. But it is increasing among the developed counties of Europe. In the future, the production of organic livestock products will be rapidly increased in South America, Middle East and Oceania, but the growth rate will be limited due to its expensive price, lack of marketing-infra and different regulation system. Most of developed countries drive organic farming policy strongly as the strategic means of rural development, diversifying agriculture system and environmental improvement.

We present a by-product of our long term photometric monitoring of cataclysmic variables. 2MASS J18024395 +4003309 = VSX J180243.9 +400331 was discovered in the field of the intermediate polar V1323 Her observed using the Korean 1-m telescope located at Mt. Lemmon, USA. An analysis of the two-color VR CCD observations of this variable covers all the phase intervals for the first time. The light curves show this object can be classified as an Algol-type variable with tidally distorted components, and an asymmetry of the maxima (the O'Connell effect). The periodogram analysis confirms the cycle numbering of Andronov et al. (2012) and for the initial approximation, the ephemeris is used as follows: Min I. BJD = 2456074.4904+0.3348837E. For phenomenological modeling, we used the trigonometric polynomial approximation of statistically optimal degree, and a recent method "NAV" ("New Algol Variable") using local specific shapes for the eclipse. Methodological aspects and estimates of the physical parameters based on analysis of phenomenological parameters are presented. As results of our phenomenological model, we obtained for the inclination $i=90^{\circ}$, $M_1=0.745M_{\odot}$, $M_2=0.854M_{\odot}$, $M=M_1+M_2=1.599M_{\odot}$, the orbital separation $a=1.65{\cdot}10^9m=2.37R_{\odot}$ and relative radii $r_1=R_1/a=0.314$ and $r_2=R_2/a=0.360$. These estimates may be used as preliminary starting values for further modeling using extended physical models based on the Wilson & Devinney (1971) code and it's extensions

Embedded system is tightly coupled with heterogeneous layers such as application, as kernel, device driver, HAL and hardware. Embedded system is customized for the specific purpose and hardware. In addition, the product cycle is so fast that software and hardware, which are developed by several vendors, are integrated together under unstable status. Therefore, there are lots of possibilities of faults in all layers. Because embedded software developers test their codes integrated with faulty layers, they cannot confirm 'whether testing of every aspects was completed, their code was failed, or integrated software/hardware has some problems'. In this paper, we propose an embedded software interface test method and a test tool called Justitia for detecting faults and tracing causes in the interface among heterogeneous layers. The proposed technique is an automated method which improves debugging upto professional testing using an emulator for helping developer.

Under the influence of growing popularity of "hallyu" (Korean wave), corporates that have copyrights such as music, movie, drama as their core competitiveness are showing continuing growth. In Addition, they built on contents are rapidly growing, interests in protection and management of intellectual property rights linked to contents are growing. Global contents development corporates are making great efforts to create profits out of copyrights. They could utilize original contents to strengthen brand value use it to produce additional contents in current market. Also they take advantage of existing storyline of the contents and strong brand to explore new markets. This paper looks into Value articulation model by Professor James Conley and analyzed the firms that utilized intellectual property rights to extend the period of protection, strengthen their competitiveness and succeeded in breaking into new market by using the rights they possess. Also, this paper examines the usage of intellectual property rights and business expansion strategy of of Iconix, the Korean entertainment company, which gained tremendous popularity in last ten years using this model. In Value articulation model, Conley classifies the process of exploiting the portfolio of the single product's(or service's) intellectual property right for a period of time into three stages ; value transference, value translation, value transportation. Pororo's strategy of utilizing intellectual property right is suggestive to domestic entertainment companies. Under the influence of hallyu" (Korean wave), domestic contents such as movies, dramas and music are enjoying the high level of popularity recently not to mention animations. In reality, Korean entertainment companies who have no background or experience of Intellectual property rights are not creating enough added values compared to fast growing market. It is believed Iconix's intellectual property rights management strategy will suggest positive aspects to domestic companies. Moreover, I hope various intellectual property rights management strategies including Conley's value articulation are studied and they can make contributions to managing domestic entertainment companies.

Most work done in CSCW (Computer Supported Collaborative Work) system has been targeted toward supporting the exchange of documents or messages among group members, and yet support for cognitive aspects such as group organization, division and merge of work, and work flow control. The objective of the study is to provide CSCW environment for the engineering design process such as CAD (Computer Aided Design) and CASE (Computer Aided Software Engineering). The proposed DCWA (Distributed Collaborative Writing Aid) system suggests a mechanism that unifies the group organization, work division, and work flow control in the CAO, CASE, and software simulation tool. In particular, CAD relates the group and work partition by providing expressing the relation of drawing object (e.g., binding, attachment, and proportional scaling) which is owned by different members of group, and CASE combining with the simulation tool supports the flexibility of the work flow control. Simulating the prototype before manu-facturing a product can reduce time and cost in development.

This thesis explains the development of multiple LCD system with the additional function to maximize the utilization of PC contents. The newly developed system is composed of host LCD and slave LCD. Host LCD decodes and outputs the image and voice of NTSC, PAL, SECAM signals. It also converts the decoded signals into LVDS signals before transmitting them to slave LCD stage. In addition, the installation of CF Memory and USB Memory helps display multi-media data. Unlike the host LCD, since not including the tuner and memory part, the slave LCD can't receive TV signals and play video signals. It only has the function to receive LVDS image signals and display on a LCD panel. This newly developed multi-LCD system has competitiveness in various aspects. With its simple structure, the failure rate, price and display power are relatively low due to its simplification of the control part. It has price and functional competitiveness as the product whose host LCD can control the entire slave LCD in terms of channel, volume, and video output.

Today's Software Systems are becoming bigger, larger and more complex than ever before. To develop largerscale projects, it is required that many experts of different fields participate and cooperate in the same project. So, it is an applied area of CSCW(Computer Supported Cooperative Works} that centers around methodologies and tools that enable cooperative works by geographically distributed people engaged in all aspects of product development. In this paper, we designed a multi-user cooperative works platform, SPACE(Software Platform for distributed Application sharing under Cooperative Environment} as a infrastructure that support to CSCW based system development for telecommunication and information system. SPACE has a fully distributed architecture under Windows 95 environment, has an application sharing mechanism enabling collaborative use of mteractive application adapt to a mixed GUI sharing technology which capture GUI and screen information, and also, an event sharing technology that has a replicated architecture.
