As more than 80 percent of tasks within corporations are performed through information systems, they have become large in scale and complicated, which make the range of the system users diverse and specialized. and as recent corporate strategies focus on the real-time environment in businesses, the organizational structure within companies tend to show frequent changes. In order to ensure the business continuity in this environment, the most important aspect is to prevent incompleteness of business by narrowing the gap of understanding of business process between the system users and the maintenance managers. In order to address this problem, this study suggests a modeling method that utilizes business scenarios reflecting actual business rules and procedures which ultimately transforms the optimized and standardized form of business scenarios into the actual software maintenance activities. This modeling method improves reusability and usability through the repeated feedback mechanism for modified software by leading to gradual fine-grained process. The feasibility of this is to be proven by applying the modeling method to the real business environment.

Smart Mirror is one of the representative technologies developed as a new communication method to escape the traditional technology by applying to the existing space. In this paper, we applied Smart Mirror to the beauty space to discover the service providing value needed to provide the beauty care service and to study the user experience for the value enhancement. In-depth interviews were conducted to investigate the user experience for enhancing the value of service provision. The results of analyzing the collected data using the affinity method were derived. Finally, the service value that can increase the user's satisfaction through the focus group interview was suggested, which suggested a way to improve the user's experience through the smart mirror.

The aim of this study is to identify the effects a gratitude promotion program has on the meaning of life and the subjective sense of well-being in female college students. As a result, it was discovered that of the sub-areas of the meaning of life in female college students, the meaning of finding and the meaning of pursuit showed a significant difference. It was also discovered that satisfaction in life of the sub-areas of positive subjective sense of well-being in female college students, love and joy of the sub-areas of subjective sense of well-being, and shame and sorrow of the sub-areas of negative emotional area had statistically significant differences. Such results suggest that the gratitude promotion program has a significant effect on the meaning of life and the subjective sense of well-being in female college students. For higher meaning of life and subjective sense of well-being in female college students, further studies on organized gratitude promotion programs and their usability should be performed.

Majority of knowledge management(KM) studies in e-government have been confined to facilitate KM within an organization. But due to citizen-centric(citizen-driven) paradigm shift and advance of web 2.0 communication in recent years, KM between governments and citizen in e-government portals is becoming an important consideration. So a series of studies on knowledge enhanced e-government portal get under way by considering that it is necessary to enhance knowledge of e-government portal and assuming it improves the usability of portal. While the topics of knowledge enhancement and e-government(portal) are widely discussed in their own domains there is a paucity of studies that address these constructs in a joint context. This paper aims to propose conceptual framework of knowledge enhanced e-government portal through structuralization of theoretical discussion with holistic approach. This framework presents an evolutional path of knowledge enhanced e-government portal that consists of three phases and it will be used for realizing the knowledge enhanced portal project as a basic reference model.

Since the launch of ChatGPT, many college students used it extensively in various ways in their curricular learning activities. This study investigates the utilization of ChatGPT in the curriculum of first and second-year engineering students, aiming to examine its influence from a learner perspective. We explored how ChatGPT is used in each subject and learning activity to understand how learners perceive the use of ChatGPT. From the survey data on engineering college students at E university, we examined students' perception on 'shortening time to perform tasks' through ChatGPT, 'dependence on ChatGPT', 'their contribution to individual capacity building', and 'their influence on academic grade'. The majority of students reported extensive use of ChatGPT for learning activities, particularly showing high dependency in liberal arts subjects and coding-related activities. While the use of ChatGPT in liberal arts was seen as not contributing to the enhancement of individual capacity, its use in coding was positively evaluated. Furthermore, the contribution of ChatGPT to the creativity in report writing tasks was highly rated. These findings offer several important implications for the use of AI tools like ChatGPT in engineering education. Firstly, the positive impact of ChatGPT's high usability and individual-capacity enhancement in coding should be expanded to other areas of learning. Secondly, as AI technology progresses, the contribution of AI tools compared to learners is expected to increase, suggesting that students should be encouraged to effectively use AI tools to achieve their learning objectives while maintaining a balanced approach to avoid overreliance on AI.

For reliable real-time interaction in a camera-tracked laser pointer system, a new idea is proposed and its feasibility is tested in this paper. In order to improve response time in the system and remove useless visual overload, the function of a laser pointer in the system is divided, the Region of Functional Interest is defined and subsequently its new interactions are introduced. Finally the experiments to measure reliability, accuracy, latency and usability are conducted and the results are presented.

In conversion of web pages for mobile devices, since existing web conversion systems eliminate unnecessary objects indiscriminately or only convert the layout of a page, the original intention of a web designer is spoiled. In spite of great advances in device technology, there still remain the problems of limited display sire and insufficient CPU power. In this paper, we propose an adaptation method that minimizes the loss of information and preserves the original intention of a web designer from the visual aspect. In image conversion, the proposed method extracts meaningful information from the background against conventional resizing methods, and performs layout-based conversion for the arrangement of image components. Experimental results show the efficiency of the method on the accuracy and the usability in comparison with existing methods.

교수학습 사이트는 교과 교육 지원이라는 특성상 그 서비스 개선에 있어서 사용자 중심적 디자인이 특히 요구된다. 기존 웹사이트 개선 연구는 단순히 웹사이트와 사용자 간의 인터랙션에서 발생하는 문제점에 초점을 맞추어 왔는데 사용자의 근본적인 니즈를 발견하고 만족시키기 위해서는 웹사이트 사용 정황의 이해라는 보다 확대된 개념에서의 접근이 필요하다. 따라서 본 연구에서는 웹사이트의 문제점 발견 및 사용자의 근본적 니즈 파악을 위하여 오프라인과 온라인 환경에 걸친 사용자 경험 관찰 프로세스를 기획하고 교수학습 사이트 서비스 개선을 위해 이를 적용하였다. 사이트 비지팅(Site Visiting), 비디오 에쓰노그라피(Video Ethnography), 사용자 다이어리 및 셀프카메라(User diary and Self camera), 그리고 인터뷰 기법이 현장 조사에서 이용되었으며 원격 사용성 평가 소프트웨어를 활용한 사용성 평가 및 카드소팅 테스트가 온라인 환경에서 진행되었다. 관찰 후 분석을 통해 교수학습 사이트의 새로운 컨텐츠 및 서비스 방향을 도출할 수 있었으며 웹사이트 사용자 경험 관찰 방법론 정립에의 가능성을 제시하였다.

In this research, a ubiquitous-based strategy for managing waterworks facilities is proposed to increase the usability of the existing related databases and to ensure the systematic way of distributing information. The current status of the existing waterworks GIS and GIS database were analyzed to achieve the goal. By studying the state-of-the-art technology, we found that importing the LBS(Location Based Service) technology to the databases is necessary. The results of these efforts are exclusive waterworks-mobile-terminals and LBS system supporting them. Furthermore, the applicability of the ubiquitous technology to waterworks has been examined to realize the real-time waterworks management.
