Sens of insecutity of the public and professionals about harmful effects of radiation is increasing in an accident at the Chernobyl and Fkushima nuclear power plant.Anxiety was amplified to lack of information about radiation majority of people. To target the middle and high school in the region of Daegu and Gyeongsangbuk-do, to investigate the radiation recognition of the next generation, it is intended to present a model of education for the safe use of radiation. The High School of the six metropolitan cities, city, town through the questionnaire and needs to be educational experience of radiation and use knowledge level of radiation, experience in daily life, understanding of man-made radiation and natural radiation, information channel on radiation, the radiation Distribute the total 800 parts of, to recover the 629 unit, was analyzed for 155 females 474 males. Many people 75.36% of the people, to 24.64% female subjects of this investigation, was constant, respectively from 13 to 18 years age. It is a large number and 30.37% of the respondents as "normal" level of knowledge of radiation, for the type of radiation, most knew. You have answer for risk experience of the medical radiation was higher, touching a lot of information via the broadcast medium in general, and the accuracy is low. I thought we wanted to be educated three or more twice a year, as an educator,about 71.37% and radiation-related understanding of knowledge and background in accordance with the diversification of information channels, the regional differences between urban and rural areas. But I considered the difference age (grade) for each is displayed, intended for junior high school students, the target surface and use the occurrence of radiation, high school students, the need for education about risk and application of radiation through this study.

This study focused on analysis of the satisfaction level of specialty shops for environment-friendly agricultural products (EFAP). To analyze the satisfaction level of EF AP, a series of household surveys were conducted. Questionnaire was prepared on the basis of the SERVQUAL model and the structural equation modeling was made on the basis of the contents surveyed. The main results of this study are summarized as follows. Firstly, tangibles structured with store clearance, neat uniform, information and others is the factor of service quality satisfaction. Secondly, reliability structured with service practice, problem solving, and service in accurate time is the factor of service quality satisfaction. Thirdly, assurance structured with the reliability of employees, sufficient knowledge of employees, courteous and good manner is the factor of service quality satisfaction. Fourthly, responsiveness structured with prompt service, voluntary help, customer response service and the like is the factor of service quality satisfaction. Fifthly, the sympathy structured in interest for each customer, provision of service in time convenient to use, encountering the customers with genuine feeling are the factors of service quality satisfaction. And sixthly, the service satisfaction factors would influence on the consumer behavior factors.

This study presents the investigation for relationship between local damage and structural performance of the 7-wire strand. This strand is often used additional reinforcement of bridges such as PSC (Prestressed Concrete) bridge and cable-stayed bridge. Stay cables are continuously damaged after completion and corrosion is the main cause of damage. Due to its structural characteristics, it is difficult to quantitatively evaluate the degradation cable damage. Therefore the relationship between local damages on strand and structural performance is experimentally and analytically evaluated in this study. The results can be used for the safety management of the cable supported bridges in the future.

본 연구는 기존 포스트텐션(외부강선) 공법이 갖는 문제점(예: 정착구 힘의 집중, 외부 돌출된 보강재의 지속적인 관리 등)들을 극복하고 보다 발전된 구조형식을 적용하고자 하였다. 노후화된 콘크리트 구조물을 대상으로 긴장재의 프리텐션을 이용하여 보수·보강이 동시에 가능하며, 우수한 미관을 제공하는 신개념의 시공 기술을 개발하고 성능을 평가하고자 한다. 본 기술은 기존 유지관리 공법들이 갖는 한계와 문제점을 극복하고 보다 효율적인 구조물 성능향상 공법을 개발하고자 한다. 또한, 본 기술은 노후된 콘크리트 거더교를 주 보강 대상으로 하지만, 인장 또는 전단균열이 발생한 벽체와 곡선 표면을 가진 콘크리트 구조물 등 대부분의 노후 콘크리트 보강에 적용 가능하고, 보강성능도 우수할 것으로 예상된다.
증강현실 환경하에서 RFID/NFC 기반의 탠저블 인터페이스를 활용한 디지털 콘텐츠 상호작용

Radio-Frequency Identification (RFID) or Near Field Communication (NFC) technology has many advantages over other visual interfaces since it does not require line-of-sight alignment, can identify multiple tags simultaneously, and does not destroy the integrity of original objects. In addition, smart devices such as smartphone and smartpad have NFC/RFID readers which can provide mobile and natural interactions with digital and physical contents. Augmented reality has an excellent visual interaction capability with digital contents in a real environment by embedding digital contents into the physical world. In this paper, we propose a new approach to digital content interactions using RFID/NFC-based tangible interfaces in augmented reality environments that utilize invisible interfaces in addition to marker-based visual interfaces. By combining the advantages of invisible and visual interfaces, more intuitive interactions with digital contents can be provided, which can remove the difficulty of using typical AR paddles that are widely used in AR interactions. In particular, a semantic AR ontology is defined to provide more convenient interactions. Through the semantic ontology-based inferencing, physical querying and filtering are effectively supported. We will show the effectiveness and advantage of the proposed approach by demonstrating implementation results.
