기술의 발전으로 인해 스마트 가전제품이 늘어나며 스마트 홈 기술이 주목을 받고 있다. 그러나 이러한 기술은 설정과정의 복잡성으로 사용자들이 쉽게 접근하기 어렵다. 특히 디지털 기기 사용에 익숙하지 않은 사용자들을 스마트 홈 기술로부터 소외시키는 결과를 낳고 있다. 본 논문에서는 사용자 친화적인 스마트 홈 시스템을 제안한다. 사용자의 시선 방향을 추적하여 디바이스를 선택하고 간단한 인터페이스의 컨트롤러로 디바이스를 손쉽게 조작할 수 있도록 한다. 또한, 생성형 인공지능과 RAG 를 결합하여 사용자가 가전제품과 자연스럽게 대화하며 정보를 얻을 수 있는 인터페이스를 제공한다.

CNC가공의 절삭공정에 대하여 명료한 분석이 되어있지 않아서 다양한 절삭조건에서의 가공결과를 예측하기가 힘들기 때문에, 최적의 절삭조건 결정 및 공구선택에 대한 체계적인 기술이 정립되어 있지 않다. 따라서, 본 연구에서는 CNC 가공기인 머시닝센터 및 고속가공기를 이용한 엔드밀 절삭가공시 요구되는 일반적인 사항들을 고찰하고, 엔드밀 공정의 가공성능 향상을 위한 절삭조건결정 방식을 지적인 결정에 의하여 선택하도록 하는 사용자 친화적 지적결정 시스템을 개발하였다.

In current algorithm trading system, general users need to program their algorithms using programing language and APIs provided from financial companies. Therefore, such environment keeps general personal investors away from using algorithm trading. Therefore, this paper focuses on developing user-friendly algorithm trading system which enables general investors to make their own trading algorithms without knowledge on program language and APIs. In the system, investors input their investment criteria through user interface and this automatically creates their own trading algorithms. The proposed system is composed with two parts: server intercommunicating with financial company server to send and to receive financial informations for trading, and client including user convenience-based user interface representing secondary indexes and strategies, and a part generating algorithm. The proposed system performance is proven through simulated-investment in which user sets up his investment strategy, algorithm is generated, and trading is performed based on the algorithm

Recently many research reports on effective use of mobile devices for museums to provide information on displayed artifacts providing individualized learning space, collaborative learning, and discovery learning, Such devices have many possibilities to support learning as a participatory media and social network. Mobile devices are used, however, limited for its usability and lack in providing expected learning experiences. It offers one-way interaction and they are often limited in providing customized services for different patrons to experience learning and entertainment. In this research, we have adopted user centered design approach to identify the needs and possible usage of PDA system in the museum. Research methods include contextual observation and inquiry with symbolic interactionism for qualitative research and its epistemology. We have developed conceptual model with scenario and storyboard method, and developed vertical prototype with Flash.

The purpose of this study was to identify affordance usability problems and to improve an interface on the Web-based Diagnosis-Supplement system from learner's perspective in order to promote to be utilized as an user-friendly system. To address those goals, user testings with 6 students from 4th grade of the primary school and 3rd grade of the middle school were conducted and the firstly improved prototypes were suggested. Then, the suggested prototypes were reviewed by experts and finalized. This study has an implication on the methodology of the usability study by evaluating the system through the Hartson's 3 affordance theory. In addition, it contributes to improving pedagogical effects by the fixing serious affordance usability problems related to main tasks of the system such as the test questions and score visualization and matching between system and real world.

In a complex, secure IT system environment there will be groups of data that be segregated from one another, yet reside on the same system. Users of the system will have varying degrees of access to specific data. The Configuration Management(CM) of the information architecture, the physical architecture, user privileges and application security policies increases the complexity for operations, maintenance and security staff. This pager describes(current work to merge the capabilities of a network CM toll with those of a Computer Aided System Engineering(CASE) tool. The rigour of Systems Engineering(SE) modelling techniques can be used to deal with the complexities of multi-level information security. The SE logical and physical models of the same system are readily tailorable to document the critical components of both the information architecture and physical architecture that needs to be managed. Linking a user-friendly, physical CM tool with the extended capabilities of a CASE tool provide the basis for improved configuration management of secure IT systems.

Using wireless communication that has been developed, it has activated electronic commerce. Thus in this kind of commercial dealing, it is more important to provide user's friendly relation rather than providers mechanical reaction to be one of the important factors. So in this paper, it describes about the development of Client Information Monitoring System(CiMoS) that accumulate user's information during the electronic commerce(wire-less) and evaluate to make server to use it in real time.

The paper presents an intelligent space management system for ubiquitous computing. The system is basically a home/office automation system that could control light, electronic key, and home appliances such as TV and audio. On top of these basic capabilities, there are four elegant features in the system. First, we can access the system using either a cellular Phone or using a browser on the PC connected to the Internet, so that we control the system at any time and any place. Second, to provide more human-oriented interface, we integrate voice recognition functionalities into the system. Third, the system supports not only reactive services but also proactive services, based on the regularities of user behavior. Finally, by exploiting embedded technologies, the system could be run on the hardware that has less-processing power and storage. We have implemented the system on the embedded board consisting of StrongARM CPU with 205MHz, 32MB SDRAM, 16MB NOR-type flash memory, and Relay box. Under these hardware platforms, software components such as embedded Linux, HTK voice recognition tools, GoAhead Web Server, and GPIO driver are cooperated to support user-friendly intelligent space.
