웹 정보 자원은 서지 자료와는 달리 인터넷상에 널리 분산되어 있으며, 그 특성상 계속하여 동적으로 변화하기 때문에, 전통적인 메타데이터의 주제 접근방식으로 접근하기는 어렵다. 또한, 인터넷상의 웹 정보 자원에 폭발적 증가는 더 이상 메타데이터 전문가가 아닌, 저작물의 생산자가 직접 메타데이터를 만들어내는 생산자로서의 역할까지 수행하도록 요구한다. 디지털 콘텐츠를 위한 메타데이터는 인터넷 전자상거래에서처럼 보다 복잡하고 다양한 용도로 그 사용범위가 확대되어짐에 따라, 디지털 콘텐츠를 위한 새로운 메타데이터 표준안은 기존 메타데이터들의 역할인 대상에 대한 세부적인 유형과 특징을 기술한 형식적 정보(syntactic information)전달기능을 제공함과 동시에, 어떠한 사건이 발생한 상황을 정확히 기술할 수 있는 의미적 정보(semantic information) 전달기능의 역할을 수행해야 한다.

USN Middleware plays roles of broker between sensors and applications. It collects sensor data, decides the situation and sends the result to the applications. It is not good to decide the situation from one sensor data, because it may error data or reflect small part of all. In this paper, we propose the disaster management model based on the concept 'group' and 'semantic information' from the sensing data. Group is the primary unit to decide the situation. It consists of several sensors which were installed in the same place and had the same pre-defined condition to act. For example, all fire sensors in the room simultaneously trigger the ring when the same pre-defined temperature is recorded. Then, the all fire sensors are included to the same one sensor group. All operations of the intelligent USN middleware are based on the 'group' unit. Disaster information is the result of the interpretation of the sensing data. based on the 'group', the disaster meaning is processed.

This paper considers an a, pp.ication of one of the sensory engineering's techniques, extraction and categorization of the sensory words, to the product of cars. The fourty five (45) sensory words are extracted in three steps. Two groups, which are characterized by whether possessing a car or not and each group consisting of one hundred persons randomly selected from the twenties or thirties, are asked to answer the questionaires with the extracted words in the five-grade semantic differential. The factor analysis is used to categorize the extracted sensory words, and shows that the words can be grouped into four categories.

Smart tourism technologies are becoming ever more pervasive and an increasing number of destinations and hospitality establishments are investing in smart tourism initiatives. However, while governments and businesses around the world are aggressively pushing the smart tourism agenda forward, smart tourism research initiatives are still in their infancy and seem to not fully cover the whole spectrum of smart tourism-related issues and questions. This paper conducts a systematic review of existing smart tourism literature to determine the status quo of smart tourism research and to identify research gaps. Considering the steep growth of smart tourism initiatives starting at the beginning of this decade, this paper reviews publications on smart tourism over the last 8 years. All publications for which the keyword "smart tourism" appears in the title, keywords or abstract were included in the sample.

The recent efforts in academia and industry represent a paradigm shift that will extend the IoT from the home environment so that it is interoperable with the Internet of Vehicles (IoV). IoV is a special kind of IoT. It allows to connect between vehicle and things located in infrastructure. Furthermore, IoV enable to create new intelligent services through collaboration with existing various services such as smart city and connected home. In this paper, we develop a service in order to realize IoV. To this end, we design a novel vehicle service platform which could automatical controlling the IoT device according to drivers' voice. To show practical usability of our proposed platform, we develop a prototype service could be call car-to-thing (C2T). We expect that our proposed platform could eventually contribute to realizing IoV.

본 연구는 법률명 용어의 의미적 성분분석을 통해 '보충적 관계속성'을 도출하고, 이를 구조적 용어사전의 관계속성 설정에 적용하였을 때 용어관계에 나타나는 효과를 확인하는 것을 목적으로 한다. '보충적 관계속성'이란 클래스(범주)별 용어들이 가지는 특징에 기반하여 만든 관계속성을 말하며, 용어사전 구축 시 도출한 관계속성을 반영함으로서 용어 간 관계가 유기적이고 명확하게 표현될 수 있도록 하는 보조적 구축지침의 역할을 하도록 한다. 이를 위해 법원도서관 '법률용어 관련어집의 316개 용어쌍을 분석하여 '보충적 관계속성'을 도출하였으며, 구조적 용어사전 용어에 적용하여 밀도 값과 밀도의 정도를 시각화하여 효과를 확인하였다. 그 결과, '보충적 관계속성' 전, 후의 변화는 적었으나 이는 법률명 용어의 특징으로 인한 결과라는 것을 알 수 있었고, '보충적 관계속성' 반영의 명확한 효과 확인을 위해서는 분석대상용어를 법률명에서 법률관련용어로 확장시켜 연구할 필요성을 확인하였다.

팀 버너스 리에 의해 '시멘틱 웹'은 1998년 제안되었으나 현재 새롭게 생성되고 있는 데이터 혹은 자연어 형식의 데이터를 시멘틱 검색을 위해 활용하기에는 아직까지 온톨로지 데이터베이스가 따라가지 못하고 있다. 이를 위해 온톨로지 구축의 구성요소인 공리(axiom)를 공공을 위한 데이터로 개발하여 시멘틱 검색에 활용하는 개념적 모델을 제안한다. 공리 데이터베이스는 단일 도메인에서 벗어난 시멘틱 검색을 위한 데이터베이스로서 도메인 온톨로지 구축에 기본적인 요소들을 제공하고, 이용자들이 시멘틱 검색을 통해 보다 만족한 정보검색을 할 수 있도록 한다. 또한 온톨로지 데이터를 확보하기 위해 정보생산자로부터 사전어휘에 대한 온톨로지 트리플을 생성하는 실험을 하였다. 온톨로지 자동구축에 대한 연구와 개발이 활발하지만 보편적 시멘틱 검색을 위해 정보생산자와 정보관리자가 많은 부분 데이터를 생성하고 검증해야할 필요가 있다.

Boryeong Mud Festival has become a representative local festival that both domestic and foreign tourists can enjoy together. In addition, it is one of the usual hands-on marine festivals in Korea that can be enjoyed with one mind at the Boryeong Mud Festival, regardless of race, age, and language. This study explored the overall perception and trends of the Boryeong Mud Festival using big data extracted online from the Boryeong Mud Festival. First, keywords such as Chungnam, hosting, summer, reporter, experience, opening ceremony, performance, operation, news, tourist, opening, event, and festival were frequently exposed online. Second, due to centrality analysis, the centrality of festival experience programs and performances, opening ceremonies, and Boryeong mayor was high. Third, due to the CONCOR analysis, five clusters of meaningful keywords related to the Boryeong Mud Festival were formed.

This study is aimed at proposing a new type of ubiquitous decision support system (u-DSS) portal which is embedded with two important mechanisms like an intelligent ontology management module (i-OMM) and multi-agent coordination mechanism (MACM). The proposed portal provides timely decision support to the involved decision entities (represented as agents) by taking advantage of the two mechanisms embedded on the portal. The most important virtue of the proposed portal is that it can resolve two problems such as semantic discordance and data confliction which are occurring very often in an ubiquitous computing environment. Frequent requests of revising the already established decision information due to the rapid changes in decision entities' requirements require the extremely flexible and intelligent u-DSS vehicle like theproposed mechanism. In this sense, the i-OMM is designed to provide support to solving the semantic discordance in the way that the i-OMM virtually integrates ontology view (IOV) to integrate heterogeneous ontology among the agents engaged inubiquitous commerce situations. Then the i-OMM sends the IOV to the MACM to resolve the conflicts among the involved agents. The proposed u-DSS portal was applied to the u-fulfillment problem in which all the involved decisionagents need their own requirements to be satisfied seamlessly and timely. The experimental results show that the proposed u-DSS portal is very robust and promising in the field of u-DSS and context modeling.

Purpose: The purpose of this study was to develop online aging and health management education for undergraduate students and to evaluate its effects analyzing the differences in knowledge and attitude toward aging and the elderly. Method: An Online aging and health management education program was established through analysis, planning, content framing and production, program application, and evaluation stages. The study sample consisted of 98 undergraduate students in one university in D city. The instruments used were FAQ I for knowledge of aging and a 20 item semantic differential scale for attitude toward aging and the elderly Results: The results of this study were as follows. First, undergraduate students' knowledge level was low and attitudes were negative at the baseline. Second, after the class, knowledge scores improved significantly from 14.44 to 20.12. In addition, the attitudes toward elderly and aging changed from negative to a more positive way showing a 23.57 point difference. Conclusion: This study shows that the online aging and health management education program was an effective educational method to improve knowledge and attitude of aging for the young generation such as college students.
