RFID 기술은 반도체 기술의 발전과 인터넷의 등장으로 인하여 지난 10여 년 동안 꾸준한 발전을 해왔으며 유통, 물류, 의료, 교육 등 다양한 분야에 적용되고 있다. 이는 향후 수 년 내에 거의 모든 물품에 태그를 부착하게 됨에 따라 유비쿼터스 환경 구축에 큰 기여를 할 것으로 기대된다. 이러한 RFID 기술은 저주파(LF), 고주파(HF), 초고주파(UHF) 및 마이크로파(M/W) 대역의 무선전파를 사용하며 각 대역의 전파 특성에 따라 동물추적, 교통카드, 물품관리, 전자화폐 등 다양한 분야에 선택적으로 적용되고 있으며, 단말기의 형태에 따라 고정형, 휴대형, 모바일 RFID 기술로 분류되고 최근에는 택시안심귀가서비스 등 휴대폰에 RFID 리더 기능이 결합된 모바일 RFID 서비스도 시범서비스를 선보이면서 우리 생활에 파고들고 있다. 또한 항만물류 관리 등과 같이 긴 인식거리가 필요한 능동형 RFID 기술을 포함하여 많은 연구와 실증실험, 시범서비스나 본사업이 이루어지고 있으며 최근에는 파렛, 케이스 단위가 아닌 물품 단위에 태그 부착을 위한 ILT 기술도 속속 선보이고 있다. 본 고에서는 시장전망이 가장 밝은 것으로 알려진 UHF 대역을 중점으로 RFID 기술을 살펴보고 이중에서도 모바일 RFID 기술을 포함한 수동형 RFID 기술, 능동형 RFID 기술 및 이와 관련한 표준화 동향을 알아본다.이를 활용한 응용 시스템에 대하여 간략히 살펴볼 것이다.

Advanced internet service and smart equipment have caused an environment supporting various online learning anytime and anywhere, which requires learning contents optimized on a new media. Among various on/off line education related to IT, most part if it is office SW. Many oh them cannot make a good education for effective training in practical because many instructors are tend to focus on teaching simple function and use examples of formality repeatedly. In this paper we propose a new office SW education system that make use of LET(Live EduTainer) based on RTE(Real Training Environment) which maximize the effect of learning and it is integrated with GBL(Game Based Learning) which gives rise to interesting in a knowledge as well as simple teaching so that learners are absorbed on it. We'll elaborate a method for teaching and learning required in this system, design and configuration of the system.

분산 네트워크 환경을 기반으로 다양한 시스템과 장비가 서로 연결되어 사용되고 있는 현재의 IT 환경의 문제점을 해결하기 위해 DMTF는 선도적인 기업 및 교육 기관과 협력하여 이기종 시스템간 상호호환성을 제고하기 위한 시스템 자원 관리 표준 규격을 제정해 나가고 있으며, 그 중 하나가 WBEM 표준이다. 이 표준에서는 공통 정보 모델인 CIM을 비롯하여 데이터를 인코딩하고 전송하기 위한 XML과 HTTP를 표준으로 채택하고 있으며, CIM 데이터를 더욱 효과적으로 표현하고 전송하기 위해 필요한 XML문서의 형식과 태그 그리고 HTTP 헤더와 오류 코드 등을 추가로 정의하고 있으며, 이들 표준의 적용에 있어 필요한 몇몇 요구사항들도 정의하고 있다. 본 고에서는 표준 규격을 바탕으로 WBEM 표준에서 채택하고 있는 데이터의 전송방식에 대해 자세히 소개하고, 끝으로 현재 WBEM 표준이 갖고 있는 문제점과 주요 이슈를 함께 살펴보고자한다.

The aim of this study was estimated the characteristics of the wave propagation by the water level conditions using a numerical modeling method at the Wando sea area. For three cases numerical simulation on the condition of incident and incoming of the deepwater design wave and the season normal wave, the spatial distribution of the incident wave at study area were investigated. And the calculated numerical modeling results were compared with measured field wave data. According to on-site wave data measured for 18 days, the range of the significant wave height and period were 0.10~1.14 m, 4.35~8.74 sec, respectively, and the maximum wave height were 0.15~1.66 m. From the results of numerical model for offshore design wave incident, the wave height attacked from Southern-East direction at this study area were over maximum 10.5 m because of rapidly change of water depth. Numerical modeling by three water level conditions of Approxmate Lowest Low Water Level(Approx. L.L.W), Mean Sea Level(M.S.L) and Approximate Highest High Water Level(Approx. H.H.W) were practiced. From the results for the case of Approx. H.W.L, variations of wave height at the back area of islands were about 1.6 m at maximum value for the case of deepwater design wave incoming. The significant wave heights of winter season were bigger than summer under normal wave condition, the incident wave height over 5.5 m decreased by shielding effect of islands. The change of maximum wave height at summer season were distinct than winter and was about 1.2 m and 0.8 m, respectively.

Recently, when a fault occurs at a long-distance point in a LVDC (low voltage direct current) distribution feeder in a light rail system, the magnitude of the current can decrease to less than that of the load current of a light rail system. Therefore, proper protection coordination method to distinguish a fault current from a load current is required. To overcome these problems, this paper proposes an optimal algorithm of protection devices for a LVDC distribution feeder in a light rail system. In other words, based on the characteristics of the fault current for ground resistance and fault location, this paper proposes an optimal operation algorithm of a selective relay to properly identify the fault current compared to the load current in a light rail system. In addition, this paper modelled the distribution system including AC/DC converter using a PSCAD/EMTDC S/W and from the simulation results for a real light rail system, the proposed algorithm was found to be a useful and practical tool to correctly identify the fault current and load current.

The aim of this paper is to analyse difficulties of the pronunciation in swedish vowels encountered by Koreans learners and to seek solutions in order to correct the possible errors. In the course of the analysis the swedish and Korean vowels in question are compared with the purpose of describing differences aha similarities between these two systems. This contrastive description is largely based on the students' articulatory speech level ana the writer's auditory , judgement . The following points are discussed : 1 ) Vowel length as a distinctive feature in Swedish compared with that of Korean. 2) A special attention is paid on the Swedish vowel [w:] that is characterized by its peculiar type of lip rounding. 3) The six pairs of Swedish vowels that are phonologically contrastive but difficult for Koreans to distinguish one from the other: [y:] ~ [w:], [i:] ~ [y:], [e:] ~ [${\phi}$:], [w;] ~ [u:] [w:] ~ [$\theta$], [$\theta$] ~ [u] 4) The r-colored vowel in the case of the postvocalic /r/ that is very common in American English is not allowed in English sound sequences. The r-colored vowel in the American English pattern has to be broken up and replaced hi-segmental vowel-consonant sequences . Korean accustomed to the American pronunciation are warned in this respect. For a more distinct articulation of the postvocalic /r/ trill [r] is preferred to fricative [z]. 5) The front vowels [e, $\varepsilon, {\;}{\phi}$) become opener variants (${\ae}, {\;}:{\ae}$] before / r / or supradentals. The results of the analysis show that difficulties of the pronunciation of the target language (Swedish) are mostly due to the interference from the Learner's source language (Korean). However, the Learner sometimes tends to get interference also from the other foreign language with which he or she is already familiar when he or she finds in that language more similarity to the target language than in his or her own mother tongue. Hence this foreign language (American English) in this case functions as a second language for Koreans in Learning Swedish.

성장기에 있어서 치아우식병발생은 특히 국민학교아동에게서 크게 나타나며 손쉬운 대책으로 발전된 것이' 치과치료사(dental therapist)혹은 치과간호원(dental nurse)제도이다. 이 제도는 약 50년전 Newzealand에서 시작되어 국민학교아동에 대한 간단한 치료와 구강위생교육급예방에 대한 제도를 주임무로 삼고 각학교에 배치되었다. 최근 이 제도는 대양주각국에 도입되어 유사업무에 임하고 있다. 한국에는 각종보조원학교가 있으나 이 제도와는 업무분야가 다르고 국민학교아동에 대한 전담제도가 확립되어 있지 않기에 '뉴-사우스웨일즈주'에 있는 학교를 예로 들어 학교의 행선적구조, 인력, 교과내용 훈련방법, 실사회활동, 급 본인들의 직업적 만족도등을 조사연구하였음.
