최근 초고속 인터넷 사용자는 꾸준하게 증가해서 천만을 넘어섰다. 그러나 사용자 액세스 네트워크(xDSL, Cable, B-WLL 등)가 다양해지고, 고부가가치의 유무선 컨텐츠 서비스가 발전함에 따라 기존의 단순 접속만을 하던 서비스는 네트워크 대역폭 보장 및 지연 방지 등의 한계에 부딪히게 되었다. 본 논문에서 제안한 에이전트 기반의 인터네트워킹 플랫폼(Agent based Inter Networking Platform)은 계층적 객체지향 시스템으로 사용자 요구(User on Demand)에 따른 다양한 서비스(Access QoS, 맞춤 응용 서비스, 보안 서비스)를 제공할 수 있다. 이 시스템은 사용자 에이전트와 에이전트 지역관리 서버 및 중앙관리 서버로 나뉘어져 있으며, 중앙 관리 서버는 사용자 에이전트로부터 할당된 대역폭, 현재 전송 속도, 지연, 현재 서비스 등의 상태정보를 주기적으로 받아서 처리한 후, 정책을 세우고, 이를 토대로 작성된 사용자 개개인의 프로파일에 따라 서비스를 하는 것이다. 시스템의 이식성과 통합을 고려해 객체지향의 모델링 기법을 사용하교 계층화된 서버를 통하여 보안에 강한 시스템을 구현하는 방안을 제시하고자 한다.

As personalized customer services create a society that emphasizes the personality of an individual, the number of product reviews and quantity of user data generated by users on the internet in mobile shopping apps and sites are increasing. Such product review data are classified as unstructured data. Unstructured data have the potential to be transformed into information that companies and users can employ, using appropriate processing and analyses. However, existing systems do not reflect the detailed information they collect, such as user characteristics, purchase preference, or purchase priority while analyzing review data. Thus, it is challenging to provide customized recommendations for various users. Therefore, in this study, we have developed a product recommendation system that takes into account the user's priority, which they select, when searching for and purchasing a product. The recommendation system then displays the results to the user by processing and analyzing their preferences. Since the user's preference is considered, the user can obtain results that are more relevant.

Current medical tourism is focused on the services of large hospitals and it is hard to find ways to attract the users. Users collect information for medical tourism through various paths in order to receive the medical consultations and customized tour services. To expand medical tourism to small and medium sized hospitals, it is necessary to have the customized medical consultations, tours and interpreter services, which are the key elements of medical tourism. This study suggests ways to provide the services based on information on medical consultations, tours and interpreter services that users had experienced directly, and also based on the platform for the essential items integrated from users, hospitals and guides' viewpoints. With information on hospitals that provide medical consultations and guides who are able to provide professional services in translation, interpretation and customized tour, users may accumulate and share the information about hospitals and customized tours verified by other users from the integrated platform. To match the contents provided by hospitals and guides with information experienced by users into a system, this study suggests the construction plan for the 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.

This study analyzes the trends of recommendation services for customized fashion styles in relation to artificial intelligence. To achieve this goal, the study examined filtering technologies of collaborative, content based, and deep-learning as well as analyzed the characteristics of recommendation services in the users' purchasing process. The results of this study showed that the most universal recommendation technology is collaborative filtering. Collaborative filtering was shown to allow intuitive searching of similar fashion styles in the cognition of need stage, and appeared to be useful in comparing prices but not suitable for innovative customers who pursue early trends. Second, content based filtering was shown to utilize body shape as a key personal profile item in order to reduce the possibility of failure when selecting sizes online, which has limits to being able to wear the product beforehand. Third, fashion style recommendations applied with deep-learning intervene with all user processes of buying products online that was also confirmed to penetrate into the creative area of image tag services, virtual reality services, clothes wearing fit evaluation services, and individually customized design services.

Recently, identifying user locations is becoming important as the society evolves into an ubiquitous society with the innovation of information technology. Particularly, many researches on identifying user locations are headed in direction to identify locations of users in the indoors, because a GPS that is widely used to identify the locations of users in the outdoors is inapplicable in the indoors. However, those researches are mostly not useful to general indoor environment because they are performed in a specific environment with specialized or customized devices such as UWB, RFID. Therefore, in this paper we propose a effective method to identify user locations in general indoor environments with wireless local network access points. Our approach enables to identify user location efficiently by measuring signal power of access points around the user and using the FRIIS formula which is used to calculate the distance among the things.
