현대 사회는 모든 분야에서 다양한 분야들의 기술들이 융합되는 사회이며, 이로 인해 각종 환경적 위험 요소 등이 존재한다. 그중 한가지는 유해 가스에 의한 피해이다. 산업이 발전하고, 편의 시설등이 늘어나면서 다양한 시설들이 설치되고 있다. 하지만 이와 함께 시설물들이 가지는 위험도 또한 높아지고 있다. 이에 본 연구에서는 센서를 이용한 위험요소 탐지와 환경측정 자료를 기반으로 일상 생활에 접할 수 있는 위험요소를 파악하고 개선하고자 하였다. 진행은 유해성분을 측정할 수 있는 센서를 이용한 시스템을 구성하고, 자료 분석을 통한 개선사항를 도출하는 방식을 취하였다.

늘어나는 인건비와 코로나 시대가 다가오면서 무인 카페나 무인 편의점 등 무인 가게가 많아지는 것을 볼 수 있다, 그러나 가게 관리자가 없음에 따라 장기 체류 고객이 가게의 기물을 파손하는 문제가 증가하였다. 본 논문에서는 CCTV를 이용하여 장기 체류 고객을 인식하고 가게 관리자에게 알려주는 시스템을 설계하였다. 장기 체류 고객 알림에 따라 기물 파손이 발생할 때 관리자의 출동 시간을 단축하는 효과가 있다.

Assessment of the implementation of a web-based courseware technology application across a merchandising program over a two-year period provides empirical evidence that students believe the technology was easy to use and useful. Results also show that the use of the application was not a hard-ship for the students in terms of time or access, that students in lower class ranks who had not had technology enhanced courses previously were more satisfied with the technology than upper class students, and that perceptions of the technology and satisfaction with it increase with experience using the technology.

Recently, according to the development of the smart home field, it provides a service to install and keep the smart home appliance in a user's residential environment pleasantly. However, the conventional system method has a problem in that it is not convenient because the user selects a device or manually operates the device. In this paper, we propose a system to set the priority of the devices selected by the user and proceed with the work. When a user selects a device, it recommends a device associated with the device. Compare and set the priority of each device. And it is a system that carries out work according to the set priority. Therefore the proposed system is expected to provide users with increased convenience and efficiency of work management.

Cloud computing technology provides economic and efficient system operation and management features to deal with rapidly changing IT technologies. However, this is less used in institutes and companies due to low security of cloud computing service. It is recognized that storing and managing important information, which is confidential in external systems is vulnerable to security threats. In order to enhance security of this cloud computing service, this paper suggests a system and user authentication reinforcement model. The suggested technology guarantees integrity of user authentication information and provides users with convenience by creating blocks for each cloud service and connecting service blocks with chains. The block chain user authentication model offers integrity assurance technology of block chains and system access convenience for SSO users. Even when a server providing cloud computing is invaded, this prevents chained invasions not to affect other systems.

In this paper, we propose a new in-hand 3D modeling system that improves user convenience. Since traditional modeling systems are inconvenient to use, an in-hand modeling system has been studied, where an object is handled by hand. However, there is also a problem that it requires additional equipment or specific constraints to remove hands for good modeling. In this paper, we propose a contact state change detection algorithm for automatic hand removal and improved ICP algorithm that enables outlier handling and additionally uses color for accurate registration. The proposed algorithm enables accurate modeling without additional equipment or any constraints. Through experiments using real data, we show that it is possible to accomplish accurate modeling under the general conditions without any constraint by using the proposed system.

The e-learning system uses multimedia content for efficiency of a education and learner's convenience. With the web based e-learning, various multimedia services are difficult on account of physical factors such as network state and system performance. Also on the off line based e-learning, we have defects an insufficiency of interactions among learners and instructors, and an insufficiency of an adaptation about the latest information. In this study, we designed a multi-tier e-learning system using hybrid multimedia method, The proposed system can provide interaction and adaptability such as web based systems, and it can provide various multimedia content such as off line based systems. In experiments results, we know the proposed system improved users' convenience and an adaptability about the latest information, and interactions among learners and instructors when compare with existing e-learning system.

Library website is medium for connecting library information resources and users. However, searching and accessing methods to information resources in library websites and retrieval systems are mostly designed for users. So, the disabled users have difficulty accessing and using library information resources through library websites. Therefore, the author carried on current status study and analysis on the retrieval system of the national and public library websites in Korea. And then, the author proposes improvement plan in order to enhance satisfaction with information needs of disabled users and to use a basic study for construction of retrieval system of library websites for disabled users.

It would cause a serious problem in the panel data when panel attrition is concentrated on certain socioeconomic groups. Using the GOMS, this study investigates whether there exists non-random attrition bias in the data and seeks for feasible solutions to minimize the bias. The results of logit analyses show that panel attrition in the GOMS results mainly from surveying system but not from the surveyed. Therefore, the result suggests to develop well-organized management skill and systems as well as to construct weighting methods.

This study is intended to suggest ways to improve the quality of the service of subtitles provided for the convenience of viewing for deaf people on e-sports broadcast content and game streamer content. Generally, subtitling files of broadcast content are manually written on air by stenographers, so a delay of 3 to 5 seconds is inevitable compared to the original content. Therefore, the present study proposed the formation of an automatic synchronization calibration system using speech recognition technology. In addition, a content application experiment using this system was conducted, and the final result confirmed that the time of synchronization error of subtitling data could be reduced to less than 1 second.
