Brain Korea(BK) 21 is a plan launched in 2000 to strengthen the competitiveness of research and education quality of universities in Korea. In this paper, we evaluate BK21 plan using both ACSI and SEM in terms of the satisfaction level of graduate students in various dimension. The results of our study indicate that in general BK21 has a significant impact on the satisfaction of the graduate students involved in BK21. It turns out that the scholarship is the only one component which is positively related to the students' satisfaction while the industry-university cooperation system and the international conference attendance and Journal publication have negative relationship with satisfaction. In addition, it appears that those who graduated from other college and participate in BK21 tend to be more satisfied than those who admitted to the graduate program from the same college. Our study results imply that some strategies for BK21 need to be modified and effectively implemented in order to increase the number of applicant of good quality and level up the satisfaction level of the graduate students in Korea.

With the development of techniques, robots are getting smaller, and the number of robots needed for application is greater and greater. How to coordinate large number of autonomous robots through local interactions has becoming an important research issue in robot community. Swarm Robot Systems (SRS) is a system that independent autonomous robots in the restricted environments infer their status from pre-assigned conditions and operate their jobs through the cooperation with each other. In the SRS, a robot contains sensor part to percept the situation around them, communication part to exchange information, and actuator part to do a work. Especially, in order to cooperate with other robots, communicating with other robots is one of the essential elements. Because Bluetooth has many advantages such as low power consumption, small size module package, and various standard protocols, it is rated as one of the efficient communicating technologies which can apply to small-sized robot system. In this paper, we will develop Bluetooth communicating system for autonomous robots. And we will discuss how to construct and what kind of procedure to develop the communicating system for group behavior of the SRS under intelligent space.

Purpose - This study, in seeking to understand the trade structure of both Korea and China, aims to strengthen Korea-China economic cooperation; it examines trade impediments by analyzing the problems affecting trade and addressing these problems, thereby discovering ways to expand trade between these countries. Research Design, Data, and Methodology - The index of trade intensity developed by the trade intensity theory (Kruger, 1997) is used to analyze the trade decision factors of both countries. Although specific factors should have materialized from the analysis of trade decision factors, determining concrete explanations is difficult in reality, as there are many unsolved and diverse factors. Results - First, the index of A value/B value is the index of Korean versus Chinese market share/Korean versus world market share, which is a measure of comparative market intensity. Second, Korea has a comparative advantage in export specialization and, conversely, China has a comparative advantage in import specialization. Third, compared to 2000, the revealed comparative advantage (RCA) indexes are considerably improved. Conclusions - This study used quantitative measurement for analysis, applying trade intensity theory, trade specialization, and RCA indexes to gauge how inter-trade relations have changed between Korea and China during the past 10 years (2000, 2005, and 2012).

Future on-board vehicle control systems can be further improved through new types of mechatronic systems. In particular, these systems' capacities for interaction enhance safety, comfort and economic viability. The Automotive Engineering Department (fzd) of darmstadt University of Technology is engaged in research of the mechatronic vehicle corner, which consists of three subsystems: sensor tire, electrically actuated wheel brake and smart suspension. By intercommunication of these three systems, the brake controller receives direct, fast and permanent information about dynamic events in the tire contact area provided by the tire sensor as valuable control input. This allows to control operation conditions of each wheel brake. The information provided by the tire sensor for example help to distinguish between staightline driving and cornering as well as to determine $\mu$-split conditions. In conjunction with current information of dynamic wheel loads, tire pressures and friction tyre/road, the ideal brake force distribution can be achieved. Alike through integration of adaptive suspension bushings, elastokinematic behaviour and wheel positions can be adapted to manoeuver-oriented requirements.

The paper investigates the antecedents of Organic Food (OF) produce in Vietnam and the intentions and behavior of OF purchasers. A theoretical framework is developed and evaluated by simulation of the structural model. Data was collected from a convenient sample of 222 consumers from Ho Chi Minh City in Vietnam. The selection included 159 (72%) women, who were identified as being the primary buyers of organic food for their family (73%). Findings suggest food hygiene issues and conscientious self-identity as the much beneficial determinants of organic production perceptions. Because of the results in this report, the consideration for food security has gained little research consideration throughout the field of organic produce. Food safety concerns are also related to academics exploring consumer confidence as they might be regarded as one of their aspects in selecting standard, natural or health food products. Findings suggest food security as one of the essential determinants of motivation, while health awareness purports to become the least significant motivation, contrary to observations from certain previous studies. However, it is observed that moral personality-identity influences both perceptions and willingness to buy organic food, stressing that the association of participants with ethical concerns influences their perceptions and eventual choices of consumption.

The main purpose of this study is to find the factors affecting the consumer goods buyers' choice on e-commerce sites in Vietnam. By using the quantitative method, the paper examines the theoretical research model and tests four hypotheses. The sample was drawn from the population of e-commerce sites in Vietnam comprising about 1,000 respondents. This study used the questionnaire method to collect primary data to test the hypotheses. Data analysis of the questionnaire was done using SPSS. The results show that there is a correlation between personal preferences of consumers on colors and brands and their actual final choice on e-commerce sites in Vietnam. The most important factor affecting the consumer goods buyers' choice on e-commerce in Vietnam is the brand of E-commerce site, following by the color and position. Among all educational groups, respondents with a Master degree pay the biggest attention to the site's color attribute, and those with a Bachelor degree pay more attention to the brand attribute. Women pay much more attention to the location of the products on the screen than men, as do consumers with a PhD degree, over respondents with a Bachelor or Master degree, and foreigners over Vietnamese consumers.

The present study aims to analyze factors of brand equity in the retail stores in Vietnam; to recognize sub-dimensions connected with the forms of brand equity and thereby study the extent of the relationship among bases of market segmentation and brand equity. The present research made a collection of data by conducting a preliminary study. Responses were collected from the customers through a structured questionnaire to buy goods and services from the retail store in Vietnam. The sample size selected for the study was 196. The study applied various statistical tools, namely, Cronbach's Alpha for reliability checking, correlation and regression statistics with the support of SPSS Software. The brand association is treated as a vital determinant of brand equity that significantly influences the bases of market segmentation. Further, the study also recognized the fact that the majority of consumers who prefer to buy from retail stores are young and in the age-group of 18-24 years. The present study made an initial attempt to study the relationship among bases of market segmentation with the factors related to brand equity; thereby to offer a novel conceptual framework designed for retail stores in Vietnam for brand positioning.

All the $Ni-Co-Ce-ZrO_2$ mixed oxides are prepared by co-precipitations methods. Methanation of CO and $H_2$ reaction is screened tested over different fractions of cerium (2, 4, 7 and 12 wt.%) over $Ni-Co/ZrO_2$ bimetallic catalysts are investigated. The mixed oxides are characterized by XRD, CO-Chemisorption, TGA and screened methanation of CO and $H_2$ at $360^{\circ}C$ for 3000 min on stream at typical ratio $CO:H_2=1:1$. In $Ni-Co/CeZrO_2$ series 2 wt.% Ce loading catalyst shows most promising catalyst for $CH_4$ selectivity than $CO_2$, which directs more stability with less coke formation. The high activity is attributed to the better bimetallic synergy and the well-developed crystalline phases of NiO, $ZrO_2$ and $Ce-ZrO_2$. Other bimetallic mixed oxides NCoZ, $NCoC^{4-12}Z$ has faster deactivation with low methanation activity. Finally, 2 wt.% Ce loading catalyst was found to be optimal coke resistant catalyst.

Most of technology information obtained from KSLV-I program have been managed by Program Life-Cycle Management System(PLMS). As involving technologies in the program require high level of confidentiality as those may be dealt with entities in international cooperation, the enforcement of strict security policy is inevitable. Therefore, a document security system has been developed to enhance protection in document management. This paper describes the overview and development status of the security system, integrated with PLMS, which aims at preventing illegal access and inadvertant leakage of the technology information.
