개인정보 유출 등의 사례가 사회적 이슈로 대두됨에 따라 개인정보 보호에 대한 중요성이 더욱 부각될 것임을 보여주고 있다. 특히, 컨택센터의 경우는 고객정보에 접근할 수 있는 인가자의 수가 다른 기업들에 비해 월등히 많기 때문에 컨택센터의 특성을 고려한 개인정보 보호기술이 적용되어야 한다. 본 연구에서는 IP Contact Center의 특징과 개인정보 보호 방안의 취약점에 대해 알아보고 기존의 시스템 내 개인정보보호기술 적용방안을 제안한다.

최근 핵가족과 고령화 등의 영향으로 반려동물과 함께 생활하는 사람들이 많아지고 있다. 특히, 1인 가구의 증가로, 외로움을 타는 현대인이 증가하면서 반려동물을 가족으로 인식하는 이들이 많아졌다. 따라서, 본 논문에서는 반려동물의 소유주들이 직면하는 문제점들을 해결하기 위하여 공공데이터를 활용한 반려동물 케어 시스템을 설계 및 구현하고, 이를 통해 반려동물을 원할히 관리 할 수 있도록 하였다.

최근 기업들은 빅데이터 활용을 통해 얻은 분석결과를 고객 마케팅 및 영업 전략 수립에 적극 활용함으로써 수익성 증대 및 비용 절감이라는 기대 효익를 달성하고 있다. 이러한 흐름에 따라 기업 내 시스템 사용자를 고객으로 두고 있는 HRM시스템 역시 인사데이터 분석을 기반으로 사용자의 기호와 요구사항을 반영한 가치 있는 정보를 제공해줌으로써 기존 기업 고객 이외에 잠재적인 고객층을 확보할 수 있는 맞춤형 HRM 시스템으로 진화해야 할 것이다. 본 연구에서는 빅데이터 기반의 인사데이터 분석의 필요성과 국외 인사데이터 분석 활용사례를 살펴보고 이를 기반으로 빅데이터 분석기술을 활용하여 사용자에게 가치 있는 정보를 제공해주는 개인화된 맞춤형 HRM시스템을 제안 및 설계하고자 한다.

통신기술의 발전이 가져온 스마트 시대로의 진입은 다양한 스마트 디바이스와 콘텐츠 및 문화를 보급, 창출해내며 우리 사회 전반적인 라이프 스타일의 변화를 선도하고 있다. 특히 국민소득의 증대로 건강에 관한 소비자 욕구가 증대하면서 더 나은 삶의 질을 추구하는 웰니스가 급부상함에 따라, 치료 중심이 아닌 예방과 케어, 힐링을 위한 다양한 서비스를 위한 디바이스와 플랫폼, 분석기술의 개발 및 적용이 요구되고 있다. 또한 단순히 서비스를 제공받던 수동적인 과거 소비자 형태가 스마트 디바이스를 적극적으로 활용해내는 능동적 소비자의 모습으로 변화함에 따라 이러한 움직임은 앞으로 단순히 서비스 제공의 측면이 아닌, 웰니스 증진을 위해 특화된 스마트 디바이스와 컴퓨터, 소비자와의 상호작용에 기반한 기술로 발전되어갈 전망이다. 본 논문에서는 건강은 물론 개인의 라이프 스타일을 포함한 라이프로그 기반의 다차원적인 정보 수집과 체계적 분석, 그를 통한 모니터링과 맞춤형 서비스를 실현하는 개인화웰니스기록을 활용한 개인맞춤형웰니스 관리 시스템을 설계하고자 한다.

Self management of chronic asthma is of great importance, since the disease could lead the patient into an emergent situation. In the present study, we describe design and implementation of a personal digital assistant(PDA) based asthma management system for personal application including symptom and medication to prevent from the potential exacerbation of the disease. The software program was written by the Visual C++ tool in the mobile computing environment and Object Store was applied for data management. User friendly GUI environment was provided for the patient to input his/her daily condition and self treatment such as medication for successful management. The input screen design substituted for keyboard input to a mouse in order to easy to select an item and minimize the keyboard input. The implementation results of this system., Real-time data collection and process were possible and be able to have been carried effectively out a continuous symptom, a medication of asthma patients, risk management.

Various applications are widely developed for smartphones to meet customer's needs. In many companies, messenger's typed interactive systems have been studied for business marketing, advertising and promotion to provide useful services for the customers. Such interactive systems are usually called as "Chatbot". In Chatbot, duplicated responses from Chatbot could occur frequently, and these make one lose interest. In this paper, we define a case that the response of Chatbot is duplicated according to the user's input, and propose a method to reduce duplicated responses of Chatbot. In the proposed method, we try to reduce duplication responses through a new duplication avoidance algorithm by building multiple tables in a database and by making combinations of user's input and its response in each table. In our experiments, the proposed method shows that duplicated responses are reduced by an average of 70%, compared with the existing method.

Tangible Space is a new emerging interaction space with mobile AR/VR computing and ubiquitous computing environment with IoT. Tangible Space spans from a physical environment augmented with virtual entities to immersive virtual environments mirroring the physical environment. Interacting with Tangible Space is logged just like interacting with the Web. By webizing Tangible Space, we can gain persistence as a by-product so that human life experience in the physical environment can be logged and shared just like the information being created and shared in the current Web. The result is a powerful future direction of the web from a World Wide Web of Information to World Wide Web of Life experiences.

The purpose of this study was firstly, to evaluate the contents of vocabulary game applications for young children's language learning. and secondly, to examine whether there is any differences between Korean and English word games in terms of the evaluation score. For this purpose, the word game applications in smart phone and tablet PC were analyzed, which included 30 Korean word games and another 30 English ones. The criteria to evaluate the contents were developed based on Children's Software Evaluation Instrument developed by CTR, the multimedia evaluation standard by Hee Sook Park, Young Joo Lee, and mobile contents evaluation standard by Soo Ui Choi. As a result, the educational value got the highest score whereas the design characteristics area got the lowest score in the whole evaluation analysis. And English word game applications mostly got higher score than Korean versions. The result of this study would suggest the way to evaluate educational game applications in use and to contribute to developing educational game contents aimed at young children's language learning.

In this study, we propose the application of exhibition contents using virtual environment technology in exhibition space. Research on the virtual environment is continuing. Particularly, research on virtual reality technology is one of the most active research fields. As researches and developments of augmented reality technologies have been carried out with the spread of smart phones, researches on virtual reality technologies have also made a lot of progress with emphasis on games and interactivity. Especially, development of hardware, software, and content is accelerating this year, including the development of various types of physical reality devices, especially HMD (Head Mounted Device) equipment and new product announcements. We want to study and apply the environment in which the system based on this virtual reality technology can approach and experience more user friendly in the exhibition space.
