The purpose of this study is to gauge the level of awareness of elementary, middle school, and highschool teachers regarding teaching-learning activities, learning space, and support for technology-based instruction in current and future school education, thereby providing essential data for seeking future improvements in the learning environment. Towards this end, a survey questionnaire (sectionalized into teaching-learning activities, learning space, and support for technology-based instruction) was developed. Subsequently the survey was administered to a random sampling of elementary, middle school, and highschool teachers in the Kyonggi, Kangwon, and Chonra Provinces. An in-depth analysis was conducted on the 797 questionnaire responses thus attained, focusing on the teachers' level of awareness regarding teaching-learning activities, learning space, and support for technology-based instruction, the correlation of the findings of the three areas in question, and the differences of the findings according to the circumstances of those surveyed. Based on the results, the authors of this study propose the following: First, that school administrators take into account the level of awareness of frontline teachers regarding teaching-learning activities, learning space, support for technology-based instruction. Second, efforts should be made to establish a safe and secure learning environment conducive to the synergic interplay of the three areas in question, by realizing true ICT in the classroom. Third, teachers in the classroom must endeavor to achieve a meaningful synthesis between educational programs and teaching-learning activities, as well as to serve as harbingers of improvements in the way we conduct the business of education.

DTN(Delay/Disruption Tolerant Networks)은 노드의 불규칙적인 움직임으로 인한 연결단절과 불안정한 연결 상태를 극복하기 위해 효율적인 포워딩 전략이 필요하다. 제시하는 알고리즘은 노드의 속도, 방향 등의 상황정보를 활용하며 이를 통해 이후의 이동성을 예측하여 포워딩할 중계노드를 선택하기 위한 방법을 고려한다. 본 논문에서는 중계노드들의 상관관계를 분석하여 안정된 경로를 제공하기 위해 노드의 상황정보를 예측하는 EPCM(Efficient Prediction-based Context-awareness Matrix) 알고리즘을 제안한다. 이를 위해 상황 매트릭스라는 상황 분석 도구를 사용하여 시간에 따라 상황정보를 저장하고, 변화의 추이를 분석하여 노드의 속도, 방향 등의 정보를 예측하는데 활용된다. EPCM 알고리즘은 예측된 상황정보를 활용하여 노드 간 미래의 연결성을 분석하고 중계노드를 선택함으로써 안정된 포워딩 경로를 제공할 수 있고, 불필요한 포워딩으로 인한 자원 낭비를 방지할 수 있다. 제안하는 알고리즘을 시뮬레이션 해본 결과 예측된 상황정보의 값이 실제의 값에 대하여 약 2%내의 오차율을 나타내어 예측의 정확도를 확인하였다.

Recently, RFID/USN is one of fundamental technologies in information and communications networks. Low-Rate WPAN, IEEE802.15.4 is a low-cost communication network that allows wireless connectivity in applications with limited Power and relaxed throughput requirements. Its applications are building automation, personal healthcare, industrial control, consumer electronics, and so on. Some applications require location information. Of course location awareness is useful to improve usability of data Low-Rate WPAN Is regarded as a key specification of the sensor network with the characteristics of wireless communication, computing, energy scavenging, self-networking, and etc. Unfortunately ZigBee alliance propose a lot of applications based on location aware technologies, but the specification and low-rate WPAN devices don't support anything about location-based services. RSSI ( Received Signal Strength indication) is for energy detection to associate, channel selection, and etc. RSSI is used to find the location of a potable device in WLAN. In this paper we studied indoor location awareness using vector matching of RSSI in low-Rate wireless PAN. We analyzed the characteristics of RSSI according to distance and experimented location awareness. We implemented sensor nodes with different shapes and configured the sensor network for the location awareness with 4 fixed nodes and a mobile node. We try to contribute developing location awareness method using RSSI in 3-dimension space.

Background: Since the terminology 'radioactive consumer product' is not quite familiar to the public and is often considered as negative and detrimental things, the educational curriculum is essential for establishing reliability of nuclear energy related and for the development of better communication strategy of radiation risk with the public. To provide base data which is valuable for establishing efficient curriculum of education and training about radiation safety, it is necessary to apprehend the different level of awareness of radiation exposures classified by various consumer products. Materials and Methods: On November 2014, a question investigation about asking awareness level of radiation exposure from various consumer products was done for university students who are highly educated. The object students are studied at a four-year-course universities which is located at Daejeon City. Results and Discussion: Although the average awareness level is comparatively low, the awareness of senior students, who major in radiation, nuclear related departments and male students are relatively high. On the other hand, the awareness of freshman, sophomore, junior students, who do not major in radiation, nuclear related departments and female students are relatively low. It is necessary to provide various information to avoid unnecessary concerns and misconceptions about radiation exposure. Conclusion: This paper will be an instrument for efficient establishment of curriculum of education and training related with radiation safety.

This study is to develop a viable measurement tool of crowdedness in restaurants. First, to measure customer’s awareness of crowdedness related to each different environmental factor in a restaurant, 49 factors of crowdedness awareness were selected based on the previous studies and then properties of each factor affecting customer’s satisfaction for crowdedness were analyzed. To analyze effects of each factor upon the satisfaction rate, a Multiple Regression Analysis was conducted with the crowdedness awareness as an independent variable and satisfaction of crowdedness as a dependent variable. The results showed that when an analysis of the environmental factors in the crowdedness awareness was conducted in an effort to develop a measurement tool of crowdedness awareness in restaurants, that would be fit for the domestic food service market, based upon 49 factors of restaurant environment. Focusing on expectation and satisfaction rate, it was found that rating the satisfaction level would be a much more effective tool to measure crowdedness awareness because satisfaction rate appeared to be more closely related to the awareness than the results obtained from the Multiple Regression Analysis with a difference between expectation and satisfaction scores as an independent variable.

Location awareness is one of the key functions to build an U-city. Recently, many of works for the location-aware systems are emerging to be applied to on-going large-scale apartment complex. For example, when dwellers or cars with active tags are move in the apartment complex, the active tags broadcast their own identifiers periodically and receivers such that routers use this information to calculate the location of the active tags. Since the active tags can actually move between routers and coordinators, it requires a hand-off mechanism. In this paper, we investigate the hand-off problem occurred in location awareness system based on ZigBee active tags. We propose and analyze a new approach for handling the hand-off problem. Through a mathematical analysis, we show that our approach diminishes the quantity of packet transfer than ZigBee's approach.

Recently, a smart space with Ubiquitous Environment is expanding rapidly due to the development of Ubiquitous Sensor Network. Therefore, more appropriate and intelligent services of the context awareness system is being required. The previous context awareness system can provide a service to the user through the inference only on the current situation. But, it does not handle certain situation properly when the system provides abnormal result. Also it does not have any proper method of generating reliable semantic data from sensed raw data. In this paper, we are trying to solve the problems as the following approaches. First, the system recognizes abnormal result and corrects it by learning feedback from the user. Second, we suggest a method of converting sensed data into more reliable semantic data. Third, we build the system based on an Ontological context model that is capable of interoperability and reusability. Therefore, the context awareness system of our study can enhance the previous system that can generate more reliable context data, can provide more effective inference method, and can provide more intelligent system structure.
