This study reports on the perspectives of Korean Chinese Japanese students (KS CS JS) on learning English at multi-cultural classrooms in Korea. The participants were 32 KS, 10 CS, and 14 JS in EFL writing classes, and the data comprised open-ended questionnaires and interviews. In analyzing the data, 'Intentional content analysis' and 'Critical discourse analysis' were adopted. The findings show that the learning of English in Korea was supported by 80% of JS, 71.9% of KS, and 50% of CS. The highest satisfaction of JS was caused by rich interactions with others. English speaking was the most difficult area for all the groups. Whereas KS (43.8%) used only Korean, CS and JS used both English and Korean for communication. Most KS (78.1%) hesitated to socialize with foreign students despite their wishes. These findings suggest that a variety of programs should be developed so that students share different cultures and use more English in the multi-cultural Korean context.

The goal of this study is threefold. First, this study explores the historical origin and architectural characteristics of cultural facilities in Japan. For this purpose, I examine various cultural facilities in Japan such as theaters, multi-purpose halls, convertible spaces and cultural centers. Second, this study also sheds a new light on the meaning of the relationships between cultural activity and architecture design in Japan. For this, I primarily look at the various categories of cultural buildings in Japan and their main functions. Finally, I demonstrate how both traditional and modem design elements are embodied in Japanese cultural facilities.

Math classes has been regarded as an independent area of a teacher and his/her students of a particular class. In Recent discussions about the professional development of teachers, for the improvement of practices, the point of view of that the community of teachers must work together is spreading. What are the considerations in organization and operation of learning communities for professional development of teachers? In this study, we analyzed the case of the learning community of math teachers in a Science Academy for the purpose of improving math classes to promote the participation of learners. Research results show that teachers share the principles and goals of mathematics teaching through the learning community. Also, through participation in learning communities, the members were practicing the lessons improved by reflection on the lessons of his/her and their colleagues. These results provide implication that it is important to provide opportunities for objectifying his/her classes through the learning community for a substantial improvement in math classes.

One important issue to generalize the ubiquitous paradigm is the development of user-centralized and intelligent ubiquitous computing systems. Sharing knowledge and correct communication between users and devices are needed to be aware of continuous changed context information and infer services for which users are suited. The goal of this paper is to describe and manage effectively the meaning of services or data which each device offers for interaction between users and devices based on semantic relationships and reasoning. In this paper, we represent semantic data using OWL and design a ubiquitous based intelligent system. We propose some index structures and strategies to process queries classified by each subsystem and adopt labeling schemes to identify classes and resources in the semantic data. We can find devices which satisfies various user's requests exactly and quickly using the proposed strategies.

According to the increasement of demand for energy around globe, the concern degree of advanced countries for ocean energy including offshore wind power becomes excited. In domestic case, the government set up a goal that jumps up to the third ranked powerful nation of offshore wind in the world until 2020 and announced "The plan for 2.5-gigawatt wind farm off the south-west coast by 2019". Also the legal basis was created in order to support development of offshore wind power as 'A law on development, use, supply and promotion for New energy and renewable energy' was established by law. However to promote offshore wind power projects, there are much difficulties that developers should be applied by permitting use of public water surface and regulations of several domestic public institution. Therefore in this paper, we suggested an alternative to promote efficient offshore wind power projects by comparative analysis between domestic and foreign on regulatory pathways for siting and permitting offshore wind facilities.

Feasibility tests on using liposomes for detecting food-borne pathogenic bacteria were studied with E. coli 0157:H7 as a model analyte. lmmunoliposomes, whose surface was conjugated with anti-E. coli 0157:H7 IgG and which encapsulated the marker dye, sulforhodamine B, were used for the detection label. Among the feasibility tests, the first test was to use a test-strip on which antibodies to anti-E. coli O157:H7 IgG were immobilized. In this format, immunoliposomes that did not bind to E. coli O157:H7 in sample were captured and then exhibited a visible signal which was inversely related with the number of E. coli O157:H7 in sample. The second test was a direct liposome assay followed by immunomagnetic separation. In this format, immunoliposomes which were bound to E. coli O157:H7 were lysed with detergent and produced a signal which was proportionally related with the number of E. coli O157:H7 in sample. The results from both formats indicate that liposomes can be utilized as a detection label.

This paper implements an integrated vehicle chassis system of ACC(Adaptive Cruise Control) and LKS(Lane Keeping System) based on OSEK OS to vehicle operating system and analyzes its performance through experiments. In recent years active safety and advanced driver assistance system has discussed to improve safety of vehicle. Among the rest, We integrate ACC that controls longitudinal velocity of vehicle and LKS that assists a vehicle in maintaing its driving lane, then implement integrated control system in vehicle. Implemented control system uses OSEK/VDX proposed standard, which is aiming at reusability and safety of software for vehicle and removal hardware dependence of application software. Redesigned control system based on OSEK OS, which is supported by OSEK/VDX, can manage real-time task, process interrupt and manage shared resource. We show by results performed EILS(ECU-In-the-Loop Simulation) that OSEK OS-based integrated controller of ACC and LKS is equivalent conventional integrated controller of ACC and LKS.

With explosion of wireless traffic it is required to further investigate the technologies on acquiring available spectrum resources and on sharing frequency with existing users. In 3GPP, it is started to study on feasibility and functional requirement of LTE standard in order to extend cellular services offered on only licensed band to 5 GHz unlicensed band. Operating scenario on LTE in unlicensed band is focused on carrier aggregation with licensed band, and the coexistence with Wi-Fi services in 5 GHz band is concerned as a major requirement. For a single global solution framework for licensed assisted access to unlicensed spectrum, listen-before-talk(LBT) mechanism of European regulation for fair access to channel under the coexistence environments is currently examined in 3GPP. In this paper, we evaluate two types of LBT, frame based equipment and load based equipment, with considering LTE carrier aggregation feature and performances of file transferred time and throughput.
