가상환경 탐색 항해 기법을 설계했다 3차원 가상환경은 입체적 시각 정보를 통해서 사용자가 가상환경을 현실로 받아들이고 마치 현장에 위치해 있는 것과 같은 감각을 느끼게 한다. 이러한 감각에 의지해서 사용자는 진지하고도 적극적으로 가상환경에 참여할 수 있다. 3차원 가상환경이 지닌 이러한 장점은 오락프로그램의 흥미 증진, 교육 및 군사훈련의 효과 향상, 의료분야의 신기술개발 등 다양한 분야에서 활용되고 있다. 그러나 3차원 가상환경은 현실 세계에 비해 빈약한 공간 인지 정보로 인해 자신의 위치를 인지하기 못하거나 원하는 목표물을 찾는데 어려움이 있다. 따라서 본 연구 에서는 가상환경을 구성하는 물리적인 정보와 가상환경의 외부 정보를 토픽맵(Topic Map)에서 제시 하는 기법을 사용하여 공간 인지 지식을 모델링 하였고, 현실세계에서 인간의 두뇌에서 이루어 지는 과정과 유사하게 3차원 가상환경 내에서도 길찾기기 가능하도록 인지맵(cognitive map)기법을 적용하여 처음 가상환경에 방문한 사용자라도 쉽게 목표물에 접근할 수 있는 개인화된 투어가이드 기법을 개발 하였다.

Globally, medical tourism draws attention as a national growth engine industry, and is actively expanding. Current medical tourism leans towards large hospitals making it difficult to attract new users. Users collect the information for medical tourism through various paths in order to receive medical consultations and customized tour services. To expand medical tourism to small and medium sized hospitals, it is necessary to have customized medical consultations, tours and interpreter services, which are the key elements of medical tourism. This paper suggests services that users can use to match medical consultations and find tours and interpreters they want at the same time. This paper suggests ways to provide integrated services based on the information experienced by users, combining the required items from the perspectives of each user, hospital and guide. To match the content provided by hospitals and guides with experience information from users systematically, this study suggests the convergence plan for a service model that can match the experience information between users and hospitals, between users and guides and between hospitals and guides systematically by operating the data in the universal container.

We develop a smart tourism information system that provides smart tourism services to free independent tourists (FITs) through various content distribution channels such as mobile apps, Instagram, YouTube, and chatbots. The smart tourism information system provides location and storytelling-based tourism information, accommodation, restaurant information, and recommended travel products so that tourists can create a travel itinerary based on personalized situation awareness. The smart tourism information system also provides smart tourism services using commercial maps, navigation, and weather forecast APIs from the Korea Meteorological Administration to provide smart tour guide services to tourists who travel according to the travel itinerary. In this paper, we develop the React Native app that provides smart tourism services provided by the smart tourism information system. The smart tourism React Native app has implemented two methods: a method that directly connects to the smart tourism information system, and a method that provides services by interworking through the GraphQL Query Language developed by META (Facebook). The smart tourism React Native app implements OSMU (One Source Multi-use) by providing tourism information from mobile apps, photos from Instagram, and drone videos from YouTube as an integrated UI.

A smart tourism chatbot is needed as a user interface to efficiently provide smart tourism services such as recommended travel products, tourist information, my travel itinerary, and tour guide service to tourists. We have been developed a smart tourism app and a smart tourism information system that provide smart tourism services to tourists. We also developed a smart tourism chatbot service consisting of khaiii morpheme analyzer, rule-based intention classification, and tourism information knowledge base using Neo4j graph database. In this paper, we develop the Korean and English smart tourism Name Entity (NE) datasets required for the development of the NER model using the pre-trained language models (PLMs) for the smart tourism chatbot system. We create the tourism information NER datasets by collecting source data through smart tourism app, visitJeju web of Jeju Tourism Organization (JTO), and web search, and preprocessing it using Korean and English tourism information Name Entity dictionaries. We perform training on the KoBERT-CRF NER model using the developed Korean and English tourism information NER datasets. The weight-averaged precision, recall, and f1 scores are 0.94, 0.92 and 0.94 on Korean and English tourism information NER datasets.

A 50-year-old Korean male tour guide without any medical or family history complained of left knee pain. After receiving umbilical cord blood injection treatment, the pain gradually worsened. After being diagnosed with septic arthritis in the left knee, arthroscopic lavage, debridement, antibiotic treatment, and routine rehabilitation therapy were performed, but the symptoms persisted. In the hospital, acupuncture, pharmacopuncture, acupotomy, Chuna manual therapy, and cupping therapy were performed in addition to the usual treatment for 59 days. To evaluate the patient's improvement, the numeric rating scale, EuroQol 5-dimension, pain disability index, and Lysholm knee scoring system were used. After treatment, the symptoms improved in all assessment tools, swelling, and range of motion of the joint. Through this study, it was found that complex Korean medical therapies may be effective for postoperative ankylosis in septic arthritis of the knee, and further studies are needed to clarify the therapeutic effect.

관광자는 타지역을 이동하면서 자신의 생각과 충돌하는 수많은 사실과 만난다. 이때 새로운 것을 알게 되고 삶에 대처하는 자신의 견해를 바꾼다. 이런 면에서 관광은 현장 적응적인 학습 방법의 하나다. 이 연구에서는 활동이론을 적용하여 관광지에서 겪는 경험과 학습의 관계를 분석했다. 활동이론의 분석단위는 관광활동의 주체, 목표, 공동체, 역할, 방법과 규칙, 성과물, 공동체와 관련성으로 설정하였다. 이를 바탕으로 관광경험에 큰 영향을 미치는 해설사·안내자와 심층면접을 진행하여 관광자의 학습과정을 분석했다. 분석결과 관광하는 동안에 일어나는 경험은 해설사·안내자의 해설과 안내의 활동체계 단위는 물론이고 단위 안에서 다양한 형태의 상호작용에 의해서 일어나고 있었다. 이 상호작용이 관광경험 활동체계의 변화를 유도하여 관광자의 학습을 가능하게 만든다. 학습 내용은 안내자와 해설사의 역할이 커질수록 학습 가치도 올라간다는 점, 관광경험이 사회적·문화적 차원의 학습 효과에 포함된다는 점, 활동체계 내 혹은 활동체계 간에는 상호작용하면서 이때 발생되는 모순의 해결과정을 관광자가 스스로 찾는다는 점, 관광경험은 고립된 단위가 아니라 계층 구조와 네트워크 교차점에 존재하기 때문에 공동체의 활동과 환경에 의하여 영향을 받는다는 점 등이다.

The main objective of this study was to find participant's recognition about and meaning of stream trekking activities by analyzing their reports after visiting Gumgang, which was a kind of field experience combined with environmental education programs. In addition, this work suggested a few points that might help improve trekking programs, trail establishment and the overall field activities along the river. Eighty reports were collected from the participants who had joined in the Gumgang trekking programs organized by both Green Korea United in Daejeon and Gumgang Basin Environmental Office of Korean EPA. A database of texts in the reports was created for the preliminary analysis and then the results were further examined in a qualitative methodology. The results of qualitative analysis demonstrated that before experiencing the trekking activities in the Gumgang, many participants seemed uninterested in a river itself, objectified it, or simply recognized functional roles. It is found that most participants preferred crossing rapids to other activities. Crossing rapids has the eleven positive aspects as follows. First of all, crossing rapids is fun and scary experience at the same time. Secondly, it is painful, but makes people feel happy ironically. Third, rapids themselves make people reminisce about their childhood and feel freedom. Fourth, they make people feel comfortable. Fifth, crossing rapids is addictive. Sixth, rapids have life. Seventh, people can learn how to adapt to nature through the experience in them. Eighth, they can make people cooperate. Ninth, they can make people recollect their old friends. Tenth, people can extend their experience near rapids to rivers. Eleventh, they can make people reflect themselves. There ere three remarkable findings about experience in rapids. Crossing rapids was an activity that most participants preferred and could make the goal of trekking in the Gumgang effectively achievable. By crossing rapids participants can understand both lively and painful parts of the river. Participants think tour guide was an essential part to trekking along the Gumgang.
