Despite the game market's expanding results from the increase of new users of mobile-game market, online-game market is faced with a stagnation. And the increase of income online-game's market share leads to decline of growth of the domestic online-game market. Online-game's growth potential is still valid, and the domestic online-games are still popular in foreign markets. But if the problem of domestic game market is not overcome, the falling behind in the competition is only a matter of time. The major problem is the lack of support measures and reduced competitiveness. On these issues, this research presents a plan to revitalizing of the online-game.

Internet of Things (IoT) services are widely used in appliances of daily life and industries. IoT services also provide various conveniences to users and are expected to affect value added of all industries and national competitiveness. However, a variety of security threats are increased in IoT environments and lowers reliability of IoT devices and services that make some obstacles for commercialization. The attacks arising in IoT environments are making industrial and normal life accidents unlike existing information leak and monetary damages, and can expand damage scale of leakage of personal information and privacy more than existing them. To solve these problems, we design a session key based access control scheme for secure communications in IoT environments. The proposed scheme reinforces message security by generating session key between device and access control network system. We analyzed the stability of the proposed access scheme in terms of data forgery and corruption, unauthorized access, information disclosure, privacy violations, and denial of service attacks. And we also evaluated the proposed scheme in terms of permission settings, privacy indemnity, data confidentiality and integrity, authentication, and access control.

U-City means the high-tech city that applied ubiquitous technology and information communication technology. U-City aims to intensify urban competitiveness and to improve the quality of residents' life through efficient management of the urban. Currently, 77 U-City projects is underway. The each project cost and scale estimate is not clear in the absence of the U-Service Standardization Model. So, many of the project are trouble about making a production the proper number of U-Service or the cost of project. The excessive service construction is reflected on the construction costs, which leads to the rise of sales price and passes onto the executor of a project as a burden of the project costs, and the problem of the delay of the change-over occurs due to supporting the operation costs for the operation of the constructed service and the demand for additional installation of facilities between a local autonomous entity and the executor of a project. In this paper, we suggested the U-Services Construction Standardization Methods and proposed the standardization services guideline of crime prevention services. U-City services in the future are able to maintain the consistency of the system through the utilization of the proposed standard model. As a result, the U-City project's pre-estimated cost and scale can be extracted.

Small and Medium-sized Enterprises are the backbones of the national economy in production and employment. Information technology can contribute to strengthening the competitiveness of SMEs. This study aims to organize the comprehensive review of existing literature on the information technology adoption and success determinants in SMEs by comparing Korean domestic and aborad studies. The results show that domestic studies tend to be more quantitative research than the research aborad. Technology-Organization-Environment framework has been the most frequently deployed framework, and CEO support and user satisfaction factors are most frequently used in the adoption and success factors. With these findings we hope the future study should adopt more various theories and qualitative research methodologies.

In this paper, we explain the DMU (digital mockup) system based on the PDM system. Most manufacturing companies are trying to develop a competitive product by increasing the quality, shortening time to market (TIM) and reducing the cost of a product. Some technologies such as SE (System Engineering), CE (Concurrent Engineering), QFD (Quality Function Development), CI (Cost Innovation) and some systems such as CAD (Computer-Aided Design), CAE (Computer-Aided Engineering), CAM (Computer-Aided Manufacturing), PDM (Product Data Management) and visualization system are adopted for these purposes. Specially, DMU system utilizes a visualization system that shows the 3D shape of a product on the computer and it gives a quick intuition to a person whether he/she is an engineer or not. It also can induce the effects of CE and QFD. SO, 0 company is developing a DMU system integrating CAD, visualization and PDM system. The main feature of the developed DMU system is that it is entirely integrated with PDM system, which means that the 3D shape of any part or assembly can be retrieved through PDM system. The DMU system will change the development process, which will increase the competitiveness of a developed product.

The domestic distribution environment of electronic goods has been placing more emphasis on securing each company's own interests and maintaining the existing customers as the most important purpose of marketing due to the change in consumption environment, the excessive cutthroat competition between retailers, the saturated number of branches for each company, weak revenue structure and declining competitiveness. In addition, the target of marketing has been shifted to specific consumers and the concept of a consumer is sub-divided into a "user" of a product and a "shopper" who buys a product. The purpose thereof is to increase the in-store purchase rate by analyzing the psychology and behavior of a shopper who actually visits a store for purchasing a product. Thus, the purpose of this study is to identify the correlation between the buying behavior of a shopper and product display based on "Digital Plaza" among the domestic electronic goods brand shops, which is selling products at various prices. This study is meaningful since it is utilized as data to plan store display for promoting purchase.
