The advance of wireless telecommunication and observation technologies leads developing sensor and sensor network for serving the context information continuously. Besides, in order to understand and cope with the context awareness based on the sensor network, it is becoming important issue to deal with plentiful data transmitted from various sensors. Therefore, we propose a context awareness system to deal with the plentiful sensor data in a vast area such as the prevention of a forest fire, the warning system for detecting environmental pollution, and the analysis of the traffic information, etc. The proposed system consists of the context acquisition to collect and store various sensor data, the knowledge base to keep context information and context log, the rule manager to process context information depending on user defined rules, and the situation information manager to analysis and recognize the context, etc. The proposed system is implemented for managing renewable energy data management transmitted from a large scale area.

The Rough Set theory suggested by Pawlak in 1982 has been useful in AI, machine learning, knowledge acquisition, knowledge discovery from databases, expert system, inductive reasoning. etc. The main advantages of rough set are that it does not need any preliminary or additional information about data and reduce the superfluous informations. but it is a significant disadvantage in the real application that the inference result form is not the real control value but the divided disjoint interval attribute. In order to overcome this difficulty, we will propose approach in which Rough set theory and Neuro-fuzzy fusion are combined to obtain the optimal rule base from lots of input/output datum. These results are applied to the rule construction for infering the temperatures of refrigerator's specified points.

As the importance of knowledge is emphasized and the environment of battlefields is changing, the military also demands competent people equipped with creativity, cooperativeness and communication ability, and in this situation it is required to apply PBL to education in the navy. The present study went through three stages in order to develop a prototype to implement a naval e PBL support system for knowledge creation. First, databases in Korea Education and Research Information Service, National Assembly Library, etc. were searched using keywords such as PBL, e-PBL, knowledge creation and knowledge ecosystem. In addition, we selected and analyzed frequently quoted literature and recent research reports related to this study among domestic and foreign theses, books, research papers, etc. recommended by specialists in contents, and derived the key values of a knowledge creation type e-PBL support system and design strategies. Second, we developed a primary prototype based on the contents of analysis and, revising it according to teaching design specialists' opinions, we proposed the final prototype of knowledge creation type naval e PBL support system and it has values as follows. First, the knowledge creation type naval e PBL support system provides learners with opportunities to apply e PBL and helps them improve their creativity, cooperativeness and communication ability and accumulate know how of services. Second, it improves work efficiency by circulating knowledge through sharing among individuals or groups, and produces synergy that promotes the organizational culture of learning. Third, the knowledge creation type naval e-PBL support system enables teachers who apply PBL to school education to find new applications of PBL in constructing knowledge bases.

Students' concepts of scientific phenomena have become a point of focus in science education research. This study investigated into developmental process and mechanism of the students' respiration concept through a cross-age study. This study utilized the 1st, 3rd, 6th grade elementary students to find out changes in student's understanding of the concept of respiration. The 1st and 3rd grade level students were interviewed what the respiration mean and whether each of living things respires, etc. The 6th grade students were interviewed and tested. Respiration is a word that students come across often in everyday life. It was found that they were more likely to associate respiration with its more common concept of breathing or gas exchange as opposed to its more scientific definition as the process in which nutrients are oxidized to provide energy. This trend didn't improve as they advanced grade. This is an indication that the knowledge system of student is split into a generic knowledge system and scientific knowledge system. Understanding of concept increased and differentiated across grade levels but that understanding was limited. They overcome their tendency to base their understanding of respiration on their understanding of human phenomena and learn to integrate their understanding of biological phenomena through a one organ - one role type of logic. They also intuitively explain everything based on their own experience.

Great attention has been paid to absorptive capacity (AC) as a means of technological innovation. However, few developing countries have demonstrated real success in the development of their technologies and economies. Global issues such as climate change, contagious disease, etc. require more active cooperation between developing and developed countries. This paper makes the novel argument that the donor's transplanting capacity (TC) should be developed and coevolved in concert with the recipient country's AC. Review of the literature shows that AC depends on a prior knowledge base and an intensity of effort. In this article, we analysed the case of KIST and suggest that codification of development experience, localization of innovation capacity, and donor committment comprise the core elements of TC. Nonaka (1994) argued that interaction between tacit knowledge and explicit knowledge can synergize to increase the overall store of available knowledge. Development experience, which leans heavily toward tacit knowledge, should be transformed into explicit knowledge for more efficient technology diffusion. The technological environments of recipient countries vary from those of their donors, which is why innovation capacity should conform to local conditions in order to make transplantation smoother. Donor committment is also critical for successfully transmitting valuable experience.

Recent trends in globalization and informatization underscore the importance of logistics. As a result, there is a need for skilled and specialized logisticians. Third Party Logistics (TPL) and Supply Chain Management (SCM) require logisticians with a broad base of knowledge in areas such as multimodal transport, international trade, information technology computers, finance, operations management, etc. This study conducted a survey to find out the opinions of demanders and suppliers. The results of the surrey show that there are more skilled logisticians in the field of management, computer works in manager level and system management. The survey also found that the certificate exam, which the Ministry of Construction and Transportation started in 1997 as the "Certified Logistics Manager" exam, should have more questions in areas such as foreign languages, computers, logistics information, management skills, etc. To produce better logisticians in Korea, the government will have to invest more into their education, especially near the major ports and metropolitan areas. In addition, it is important that universities and companies work together to provide students with internship and other field-experience teaming opportunities. Logistics education centers should be built at the national level. In addition, the existing certification should be divided into two separate certifications: one for ordinary logistics, and one for international logistics. To further improve the certification system, short-answer or essay questions should be added to the second exam, and an additional certification for the highest level logisticians, a so-called "professional logisticians certificate," needs to be introduced.ntroduced.

Smart farming education service focuses on the dissemination of farming information that is the farming knowledge, farming skill, and farmer's experiences and knowhow, etc. This farming information is supposed from current activities, farming product and from the experience of farmer on the field. If the information is not available, or if available and not in a form that is amenable to being brought to the end producer then the process stalls at this point. The core component of the automation process for smart farming education service is the creation of a data store which will be a repository for the information of the smart farming education. The farming sector will benefit immensely from the implementation of farming data in farming contents repository which will serve as the knowledge base for the smart farming education service.

A location-based service or LBS in a cellular telephone network is a service provided to the subscriber based on his current geographic location. This position can be known by user entry or a GPS receiver that he carries with him, but most often the term implies the use of a function built into the cell network that uses the known geographic coordinates of the base stations through which the communication takes place. One implication is that knowledge of the coordinates is owned and controlled by the network operator, and not by the end user. Location utility service provides two kinds of functions, geocoder and reverse geocoder. Geocoder converts an address into a coordinate and reverse geocoder changes a coordinate into an address. Because location utility service is the first step to progress LBS, various servises such as directory, routing, presentation, and etc require to access that. In this paper, we will describe the architecture of LBS platform and the concept and the role of location utility service.
