This paper categorized Korean small and medium businesses' global capabilities based on the preceding studies about the global capabilities and then, examined how their global capabilities would affect their competitive advantages and business management performances. As a result of testing the research model, it was found that the small and medium businesses' global capabilities had some significant effects on their competitive advantage (p<.001). On the other hand, the global capabilities had some positive effects on the business management performances and the mediating effects were significant (p>.05), which means that the competitive advantage has some mediating effects on the correlation between the global capabilities and the business management performances. Accordingly it was possible to analyze the correlation between global capabilities of small and medium businesses and their competitive advantage and thereby, provide for an opportunity to shift the paradigm of the global competition strategies.

Nowadays, the increasing global competition forces manufacturing enterprises to apply new technologies such as laser welding to manufacturing of their products. In case of automotive industries, they interest in assembly system for BIW (Body in White) carrying out laser welding. In this paper, the method of implementation for digital laser welding assembly system is proposed. Based on the requirements of assembly tasks obtained through product analysis, process modeling is executed by using the IDEF0 and UML model. For digital assembly system, the selected components are modeled by using 3D CAD tools. According to the system configuration strategy, lots of the alternative solutions for the assembly system of welding side panels are generated. Finally, the optimal laser welding system is chosen by the evaluation of the alternative solutions with TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method.

Purpose: The purpose of this study is to find that university advertising and PR which are five factors influence on prep students are choosing university. Methods: The collected data through the survey using causal effect relationship. Results: The results of this study are as follows; First university advertising positive influence on choosing university. Especially, high school visiting and recommend of home room teacher are strong influence on the university choosing Conclusion: Today, regional universities are now intense competition between schools to attract students. Thus they must suggest short-and long-term strategy, vision of university, IEP, industrial-educational cooperation, international program and others for prep students through university advertising and PR.

Noweays, The flow of international relations have to competition with product of each nation, a means of this competitoveness is developmennt of goods based on nation culture. That is in need to development of design have color of our country make sure of original design. Now we need a positive opposed to wants of consumers with expaneded market, so as to need of develogment of distinctive design. And then, this stuey have purpose analory of distinctive design as a ilustrate to case of traditional design with on a conjoint analysis, look into the modeling method and meaning of traditional design. At first, it setting up the base of design development, as a present into a investigate to extract course of shape's element for design distinction. And look around about the developing case of domestic company and modeling method, a pattern of traditional design development, As on of distinction's way has doing conjoint analysis for abstract to character of traditional form and have devdloping to product with a present expression elements and design concept for a basis.

Industrial management can be achieved in the improvement of productivities and goods qualities, only copy with international competition through technological renovation, This compels the renewal and augment of production equipments, for which more investment has to be projected. Equipment investment, However, has the possibility of assuring the expectation of profit, but the capricious reality of economical situation caused by inflation requires the precedent study of exmining, analyzing and assaying the effect of equipment investment for a long term. The resolution must depend on a technique of what is called engineering economy, which scrutinizes some samples of investment analysis under price fluctuations, which designates through a method of direct calculation that the only less scale of primal investment never bestows wider profit, and recognizes what contribution engineering economy has to the decision making of management.

Since 3DTV was introduced, the market could not grow further due to the several causes such as the lack of content, technology for production and display and eyestrain. However, the rapid advances of the technologies on digital broadcasting, consumer electronics and computer enabled the commercialization of 3D animation, computer graphic, 3D advertising as well as 3D movies, and since then the international technical competition is growing fiercer. Since much more companies introduced the solutions for 3D in NAB 2010 than 2009, the expected size of the market will be bigger than ever before. This article describes the recent trends and the prospect of the 3D technologies including national defence strategy, content, construction, consumer electronics, advertisement, and terrestrial 3D1V pilot project in Korea.

Standards impact the economy in various ways. Moreover, intense competition exists between a variety of standards in this era of globalization. This paper quantifies the economic effect of multiple standards in the Information Communications and Technology (ICT) sector. Thus, it identifies and specifies which standard applies when economic gains exist. A model is developed which quantifies the magnitude of the economic effect of multiple standards as compared with a single standard or no standard. The model allows for both the micro- and macroeconomic gains from standardization to be quantified. Preliminary estimates indicate that at the macro level the multiple standards multiplier is approximately three. That is for every dollar invested, the gain is on the order of three dollars. Although not as robust. preliminary results indicated a similar economic gain at the micro level Overall, multiple standards dominate a single standard. This paper applies the model to IMT-2000, an example of multiple standards, to demonstrate this approach to quantify the standards economic effect.

"Artificial Intelligence+" is a key strategic direction that has garnered the attention of several global medical device manufacturers and internet companies. Large hospitals are actively involved in different types of medical AI research and cooperation projects. Medical AI is expected to create numerous opportunities and advancements in areas such as medical imaging, computer aided diagnostics and clinical decision support, new drug development, personal healthcare, pathology analysis, and genetic disease prediction. On the contrary, some studies on the limitations and problems in current conditions such as lack of clinical validation, difficulty in performance comparison, lack of interoperability, adversarial attacks, and computational manipulations are being published. Overall, the medical AI field is in a paradigm shift. Regarding international standardization, the work on the top 10 standardization issues is witnessing rapid progress and the competition for standard development has become fierce.
