PurposeThe purpose of this paper is to develop a theoretical framework of an integrated digital library (DL) system based on knowledge management (KM) process.Design/methodology/approachThe study is based on viewpoints, review of existing concepts and frameworks of DL and KM, and the result of an interview of nine DL practitioners world‐wide. The respondents are purposively selected from the participants” lists of two international conferences held in 2008. The interview is conducted through e‐mail using a short, structured and open‐ended questionnaire.FindingsThe study finds some significant overlaps between DL and KM and argues that a generic KM process of acquisition, organization, storage and retrieval, and dissemination of knowledge with receiving feedbacks can suitably be fitted in DL. Thus an integrated DL system can be consisted of digital resources, technological infrastructure, experience and expertise, DL services and a KM process. The integration of KM can add value to developing a knowledge‐based culture, management of intellectual assets, promotion of knowledge sharing, innovations in DL services and a strong leadership position for DL.Research limitations/implicationsThe research presents theoretical viewpoints of DL and KM, and the model, therefore, demands for practical investigation.Practical implicationsThe study suggests the adoption of KM process in DL system to enhance its effectiveness.Originality/valueThe proposed model is an original work and theoretically, it would contribute to the advancement of academic debate in both the areas of DL and KM.
We propose a support system for finding lost objects indoors. The system employs active RFID and ultrasonic position detection to detect the position of a lost object. The system illuminates the position by using Movinglight, which is normally employed in stage lighting. From an experiment, the way of notification by light is better than that by sound in some situations.
In this paper, we propose an interactive system for controlling the pressure while cutting paper with a knife. Our system supports skill improvement for novices by measuring and evaluating their cutting pressure in real time. In this study, we use a knife with a blade attached to a stylus with a pressure sensitive sensor, which can measure the pressure, coordinates, and cutting time. We compare the cutting pressure values of novices with those of artists and thereby observe the difference in their cutting skills. We have also developed a practice system that guides the novices on controlling the pressure by providing information on the cutting pressure values of experts. This system shows the difference in pressure between novices and experts using a synchronous display of color and sound. Using these functions, novices learn to adjust their cutting pressure according to that of experts. The purpose of this research is to improve the cutting skill of novices learning the art of paper-cutting. Instructors typically teach the novices how to control the cutting pressure during paper-cutting workshops, as novices tend to cut paper with an unstable and higher pressure than necessary. Determining the right cutting pressure is a critical skill in the art of paper-cutting, and we aim to improve the same with our system. We verify the effect of our system by practicing paper-cutting in various methods and comparing the cutting pressure values obtained. It is evident from the results that novices who practice with our system show progress on the average and variance of cutting pressures.
To improve the cutting skills of learners, we developed a method for improving the skill involved in creating paper cuttings based on a steering task in the field of human-computer interaction. TaWe made patterns using the white and black boundaries that make up a picture. The index of difficulty (ID) is a numerical value based on the width and distance of the steering law. First, we evaluated novice and expert pattern-cutters, and measured their moving time (MT), error rate, and compliance with the steering law, confirming that the MT and error rate are affected by pattern width and distance. Moreover, we quantified the skills of novices and experts using ID and MT based models. We then observed changes in the cutting skills of novices who practiced with various widths and evaluated the impact of the difficulty level on skill improvement. Patterns considered to be moderately difficult for novices led to a significant improvement in skills.
In this paper, we aim to measure the cutting skill for creative paper cutting and increase practice effect. The practice effect changes according to the difficulty level of the cutting pattern and the skill level of the user. The cutting pattern of the picture consists of a straight line and a curved line, and we generalized the index of difficulty (ID) based on Steering law. One of cutting skills that shows the difference between novices and experts is time to cut. Besides, we developed a system consisting of a drawing display and a stylus with a knife to measured the cutting movement times (MT). The system measures MT according to the ID of the cutting pattern. We confirmed skill improvements by measuring changes in MT with various patterns. Additionally, we measured the reduction rate of MT to investigate the effectiveness of practice with various IDs. As a result, we confirmed the difference in practice efficacy according to each IDs.
Human posture classification is one of the most challenging issues in smart homecare system. To achieve high classification accuracy, we propose a new algorithm, called range-based algorithm. In this paper, a range means the distance between body parts. The ranges between body parts are investigated to classify the human posture and to detect a possible fall-down accident. Furthermore, we also proposed an adaptive posture window scheme to recognize the human posture in real-time even though human change the posture in different speed. The results reveal that our proposed can classify the human posture and detect fall-down with high accuracy and reliability.
Currently, Japan is rapidly aging. Japanese government agencies report that the percentage of elderly people whose ages are at least 65 years will increase by up to about 30 percent in 2025. As one of the measures towards this situation, the community-based integrated healthcare system will be introduced in Japan. The system aims to provide elderly people living at home with appropriate health, medical, and welfare services. We focus on the burden of sharing information on the situation of the elderly at home among health, medical, welfare staffs, and neighbors. We have been developing a supporting system for sharing information on the situation of the elderly at home and conducted a field test around one year. We consider that various stakeholders involved in the community comprehensive health care system could recognize the importance of information sharing and collaboration with them through this kind of social implementation
The emergence of social networking services on the Internet has facilitated communication between people located far away from each other. Through a variety of Web services, people can get together on a virtual platform to video chat, edit documents, and engage in other activities; however, neighboring residents do not always have a chance to meet each other face-to-face.In our research, we focus on people living close to each other and try to encourage them to get together. We have attempted to encourage people to bring along their own ingredients to a get-together for cooking and eating according to "Osusowake," a traditional Japanese ritual. We propose a menu-planning support system that utilizes the shared information of cooking ingredients owned by individuals.
