본 논문은 유비쿼터스 패러다임에 맞는 새로운 게임으로서 디지털 피지컬 필드게임을 제안하고자 한다. 이를 위해 산업 혁명과 정보화 혁명과 같은 사회적 패러다임의 변화에 따른 게임의 변화를 소통의 측면에서의 상호작용을 중심으로 살펴보고, 기존에 존재하는 유비쿼터스 게임과 그 한계점을 살펴보았다. 그리고 이러한 한계점을 극복할 수 있는 유비쿼터스 패러다임에 맞는 새로운 게임으로서 디지털 피지컬 필드 게임을 설계하였다. 또한, 이해를 돕고자 설계한 게임을 가장 잘 보여 줄 수 있는 실제 사례를 제시하였다. 이러한 연구를 통해 유비쿼터스 게임의 활성화에 도움이 될 수 있으며, 테마파크 및 체험관에 적용되는 기능성 콘텐츠로서 게임의 영역을 확장할 수 있을 것으로 기대할 수 있다.

Purpose: The existing web sites for premature babies are operated by non professionals and thus do not provide any medical or professional information necessary for rearing premature babies. The purpose is to construct a new website with lots of medical and professional tips for premature babies. Methods: First, topics of discussions are collected from the bulletin boards of three websites, operated by non professionals, for premature babies. And new website for premature babies is constructed based on the identified topics and also based on professional consultation with six professors. Results: The newly constructed website provides professional tips for the above topics as well as introduction of it's object, general medical information and baby rearing information and the bulletin board for parents of premature babies. Conclusion: By providing professional tips for mothers of premature babies, the new website is expected to provide detailed, accurate and professional information on issues most parents of premature babies concern.

It is well known that crystal growth is an essential area of research for optoelectronic materials. In the present paper the growth techniques and the advanced progress in development of crystal materials important for optoelectronic applications are described. New growth techniques, developed in the authors' laboratory, enabling the introduction of expanded applications of new materials are presented. After a review of recent developments of new techniques for optoelectronic materials, own experimental studies will be discussed.

DEUTZ AG, co-founded in 1864 by Nicolaus August Otto, the inventor of the four-stroke cycle engine, has developed the new 2013 engine for commercial vehicles on the basis of the tried and tested 1012 and 1013 series. With 4 and 6 cylinder models, the engine covers the power range between 100 and 190 kW. At the time of their introduction to the market, the engines will meet the exhaust emission legislation of EURO IV and incorporate the potential for EURO IV, Further engineering targets were. (Compactness, Favourable power/cost relation, Low weight, Low fuel consumption and Low noise level). All targets could be accomplished in a relatively short development period via the application of modem simulation tools and test methods. In this paper, the design configuration of the engines is described with particular emphasis on measures for noise emission reduction and the combustion system including injection and turbo charging. Furthermore, we demonstrate the engine's potential to fullfill the European emission legislation EU4, which comes into force in 2005.

Advanced nuclear power plants are generally large complex systems automated by computers. Whenever a rare plant emergency occurs the plant operators must cope with the emergency under severe mental stress without committing any fatal errors. Furthermore, The operators must train to improve and maintain their ability to cope with every conceivable situation, though it is almost impossible to be fully prepared for an infinite variety of situations. In view of the limited capability of operators in emergency situations, there has been a new approach to preventing the human error caused by improper human-machine interaction. The new approach has been triggered by the introduction of advanced information systems that help operators recognize and counteract plant emergencies. In this paper, the adverse effect of automation in human-machine systems is explained. The discussion then focuses on how to configure a joint human-machine system for ideal human-machine interaction. Finally, there is a new proposal on how to organize technologies that recognize the different states of such a joint human-machine system.

The introduction of new access technologies in 5G radio networks has had a considerable impact on the design of transport networks. Research activities are underway on new transport technologies in both the wireless and optical domains to support 5G transport. This paper provides an overview of the concept and requirements of a fronthaul. We also discuss the research activities of a new fronthaul interface for future 5G networks, a 5G integrated fronthaul/backhaul transport network (5G-Crosshaul), a next-generation fronthaul interface (NGFI), a mobile xhaul network (MXN), and a next-generation mobile fronthaul architecture with multi-IF carrier transmission scheme.

새로운 에너지 기술이 기존 사회시스템과 공존하며 확산되는 과정은 저탄소 사회로의 전환을 위해 꼭 필요하지만 어려운 여정이다. 정부주도로 추진되고 있는 서남해 2.5GW 해상풍력사업은 대용량 신재생에너지발전을 중앙전력계통으로 연계하는 것을 목표로 추진되고 있다. 따라서 성공적인 해상풍력 발전의 도입을 위해서는 기존 사회기술시스템의 전환도 병행되어야 한다. 본 연구는 다층적 관점과 전략적 니치관리를 방법론으로 해상풍력기술의 니치전략 적용에 대한 에너지 시스템 전환을 분석한다. 연구결과로서 새로운 기술이 기존 레짐(regime) - 환경상황(landscape)과 연계, 소통을 거쳐 성장하는 과정을 다층적으로 분석하고 에너지체제와 신기술의 관계의 변화를 구조화 하였다. 또한 전략적 니치관리 연구를 적용하여 니치실험 착수단계에서 내재하는 장애요인을 진단하고 해상풍력 실증사업 지연의 원인을 파악하였다. 이를 통해 해상풍력 니치기술이 에너지체제와 다양한 제도 속에서 안정적으로 성장할 수 있다는 실천적 시사점을 도출하였다.

Fig. 8 summarizes the present status of high yield pulp production and the directions of research on modification. A thick line indicates pulping process presently in use. As mentioned previously, one kind of modification is to introduce hydrophilic groups onto the pulp. Still unsolved is whether or not the introduction of hydrophilic groups should be restricted to lignin only. Goring (28) reported that middle lamella lignin has fewer phenolic hydroxyl groups than cell wall lignin and suggested that such a difference in the lignin may be useful in the removal of middle lamella lignin. The introduction of hydrophilic groups onto pulp may not be enough to modify high yield pulp. The removal of some portion of carbohydrate may be also necessary from the standpoint of softening of pulp fibers. There is no information at what lignin and carbohydrate, and how much should be removed. The combination with synthetic high polymers may also be important in modifying high yield pulp. Prof. C. Schuerch of the State University of New York who was a visiting professor at the University of Tokyo in 1974, mentioned that the hydrophilicity of lignin would be promoted, if phenolic hydroxyl or carboxyl groups could be introduced into the aromatic nucleus of lignin. If this were possible. this process would also mean a pulp yield of more than 100%. This idea is just one example of the expectation made possible through lignin chemistry. Instead of the introduction of hydrophilic group, the oxidative degradation of aromatic nucleus of lignin may also be useful in promoting the hydrophilicity of pulp. In this case, ozone may be an excellent chemical. However, there are a lot of problems to be solved such as homogeneity of reaction and selectivity of ozone for lignin. The above ideas are summarized in Fig. 9. There are many problems to be solved in the production of an excellent high yield pulp which is comparable to chemical pulp. The information from wood chemistry hopefully will elucidate some of the problems mentioned above.

The bill of lading serves to link imports and exports. It is the last document issued in the export process and is the most important document before import and export as it is the first document required for importers to take over goods. Transfer the right to the goods to be transported to another person through endorsement. The role and importance of the bill of lading has already been suggested in many previous studies and the trading partners are fully aware of it. In addition, all countries and international organizations recognized the importance and enacted various laws and systems in relation to possible legal problems and they have become customary in practice. However, trade fraud that exploits the characteristics of the bill of lading may occur. In order to solve this problem, various attempts related to the electronic rights transfer of the bill of lading began to be carried out, and many institutions and companies are still trying to develop a new system. As a result of these efforts, electronic bills of lading, such as bolero, appeared, and electronic bills of lading, which can transfer rights in an electronic way, appeared. Therefore, this study intends to present the feasibility of the introduction of smart bills of lading after examining the current status of electronic bills of lading and the introduction of block chain technology-based bills of lading.
