The visualization of three dimensional geophysical data is forcing a revolution in the way of working, and allowing the discovery and production of hydrocarbons at much lower costs than previously thought possible. There are many aspects of this revolution that are behind the scenes, such as the database structure, the storage and retrieval of data, and the exchange of data among programs. Also the user had changes where the interpreter (or manager, or processor) actually looks at and somehow interacts with the data. The use of opacity in volume rendering, and how its judicious application can assist in imaging geologic features in three dimensional seismic data. This revolutionary development of new technology is based on the philosophy of synergy of inter-disciplines of the oil industry. Group interaction fostered by large room visualization environments enables the integration of disciplines we strive for, by putting the petrophysicist, geologist, geophysicist, and reservoir engineer in one place, looking at one image together, without jargon or geography separating them. All these tools developed in the oil industry can be applied into the civil engineering industry also such as the prior geological and geophysical survey of the constructions. Many examples will show how three dimensional geophysical technology might make a revolution in the oil business industry now and in future. This change can be considered as a fusion process at data, information, and knowledge levels.

Development of digital information and internet technology causes the changes of technology environments and companies, and the variety of customer needs has been dynamically changed in terms of integrating information system with customer satisfaction. Moreover a new logistics concept is needed through the sharing information between suppliers and consumers, which maximizes the level of customers service and its flexibility by changing functional-oriented to process-oriented. In other words, Supply Chain Management (SCM) is now considered as a key aspect of business, which controls the flows of information, funds, and goods in the supply chain. Rationalization of transport-delivery system will be one of the most important issues on logistics management to the domestic companies. The companies need the effective delivery system. Especially in the case of delivery system from distribution centers to customers or vendors, it might take a long time to control the delivery system manually because it would be hard to apply the automatic vehicle routing algorithm effectively considering all the practical constraints. Thus this study develops a heuristic algorithm of automatic vehicle delivery support system in terms of grouping by short ranges of vehicle movement utilizing postal coordinates, which satisfies a variety of realistic constraints and reduces controlling time of manual operations. In addition, the performance of the algorithm developed in this study is evaluated through the case study.

서비스기업의 물리적환경은 고객들의 서비스 품질인지와 구매 행동에 영향을 미친다는 연구가 있어왔다. 그러나 쾌락적 욕구와 실용적 욕구에 의한 구매는 다른 경로를 통하여 구매의도에 영향을 미칠 것이라는 가설을 갖고 본 연구를 시작 하였다. 본 연구에서는 쾌락적 욕구에 의한 구매가 많을 것이라 판단되는 국내 커피전문점을 이용하여 서비스 업장의 물리적 환경이 미치는 영향을 실증연구해본 결과: 커피전문점의 물리적 환경 요인인 분위기, 인테리어, 청결은 고객의 감정에 직접적인 영향을 미치는 것으로 나타났으나 종업원의 외모는 감정에 유의한 영향을 미치지 않는 것으로 파악되었다. 그리고 물리적 환경이 구매의도에 미치는 영향은 감정을 경유한 간접영향을 미치는 것으로 나타났다.

With the rapid growth of internet infrastructure, World Wide Web is evolving recently into various services such as cloud computing, social network services. It simply go beyond the sharing of information. It started to provide new services such as E-business, remote control or management, providing virtual services, and recently it is evolving into new services such as cloud computing and social network services. These kinds of communications through World Wide Web have been interested in and have developed user-centric customized services rather than providing provider-centric informations. In these environments, it is very important to check and analyze the user requests to a website. Especially, estimating user preferences is most important. For these reasons, analyzing web logs is being done, however, it has limitations that the most of data to analyze are based on page unit statistics. Therefore, it is not enough to evaluate user preferences only by statistics of specific page. Because recent main contents of web page design are being made of media files such as image files, and of dynamic pages utilizing the techniques of CSS, Div, iFrame etc. In this paper, large log analyzer was designed and executed to analyze web server log to estimate web contents preferences of users. With mapreduce which is based on Hadoop, large logs were analyzed and web contents preferences of media files such as image files, sounds and videos were estimated.

To ensure competitiveness in the modem automotive market, process and material planning should be performed concurrently with new car developments. In automotive general assembly shops, thus, new business workflows and supporting environments are inevitable to reduce the manufacturing preparation time in developing a new car in the manner of concurrent and collaborative engineering. Since complete material planning for a whole general assembly system is a huge and complex job, several planners should execute their planning jobs and share information. Therefore, each planner should provide others with his/her results with continuous on-line communication and cooperation. In this research, a web-based system for concurrent and collaborative process and material planning for automotive general assembly via 3D digital mock-up S/W is developed. By using this system, savings in time and cost of process and material planning are possible, and the reliability of the planning result is improved.

In this paper, we report a system specifications of Hi-resolution and four-screen stereo image projection system which was established in VBL(Venture Business Laboratory) at Tokyo Institute of Technology on 3rd July 1996. The system is 3m $\times$ 3m $\times$2.2m rectangular parallelepiped composed of three 150inch side screens and floor. Host computers can generate virtual environment s in real-time and four projecters project these images to the screens. Viewers are, therefore, surrounded by these screens and an illusion of immersion can be created. Because, the views of users are completely covered with the projection images and many kinds of interactive devices can be used in this system. Moreover, many users can have experience the virtual environments at the same time. Usually, this kind of system uses hi-performance graphics workstations for host computers. One is SGI(Silicon Graphics, Inc.) Onyx with 3 Reality Engines. The other system is 4 personal computers. Because hi-performance and low price graphics accelerators for personal computer have been developed in these years, the abilities of VR(Virtual Reality) systems based on personal computers should be investigated.

The objective of the current study was to analyze the major factors affecting quality of life improvement for contract foodservice customers by identifying the contract foodservice environment consisting of the customer, foodservice management, and competitor. Qualitative research method was performed on foodservice customers and foodservice management using in-depth interviews. First, the customer environment was classified into three categories, including convenience of location, foodservice management environment into six categories, including comfort level of dining facility, and competitor environment into three categories, including service competition between foodservice providers. Second, quality of life was defined as the level of contentment felt by both the customer and foodservice management consuming the food provided. Third, both the customer and foodservice management perceived that the management environment of contract foodservice had a "medium" effect on quality of customer life. The findings of this study could be applicable for development of a contract foodservice business strategy through objective comparative analysis of the customer, foodservice management, and competitor environments.
