PURPOSE: This study examined the status and prospects of telerehabilitation to identify the challenges and propose strategies for its promotion both domestically and internationally. The study also focused on the preconditions and improvements required for adopting telerehabilitation, considering technological, institutional, and socio-cultural factors. METHODS: A thorough database search was conducted. The relevant research, papers, and reports were collected, and the literature was evaluated to summarize the findings. RESULTS: Tele-rehabilitation showed promise in enhancing the healthcare service quality and accessibility. However, addressing challenges requires a comprehensive analysis of its status, global research trends, and the formulation of adoption strategies. Research in this direction is expected to improve healthcare services. CONCLUSION: Tele-rehabilitation can enhance healthcare services by overcoming geographical limitations. On the other hand, addressing challenges through analysis and strategic planning is essential for its effective adoption and advancing healthcare quality and accessibility.

Evaluating ubiquitous computing services is important for the commercialization of the ubiquitous services which will be running on electronic markets. However, despite its importance and usefulness, assessing ubiquitous computing services is still in its early stage. Moreover, sufficient study of making a distinction what are 'ubiquitous computing services' or not has not been provided yet. Hence, this paper aims to propose an integrated methodology to assess the ubiquitous computing services. A multilayered approach is considered to assess not only technical but also behavioral perspectives. To show the feasibility of the assessment model, three use cases are studied and evaluated.

Mashups are new type of interactive web applications, combining content from multiple services or sources at run time. The www is currently experiencing a revolutionary growth due to its increasing participative community software applications. One of the interesting aspects of the Web 2.0 evolution is the wide-availability of various Web applications as APIs or Web services. These APIs expose informational services on the Web and take many forms of remote invocation of functions using standard Web protocols and XML for data representations. The paper describes mashups from a number of angles, highlighting current developments while providing sufficient illustrations to indicate its potential implications.

The popularization of smartphones in recent years has created a rich ground for online-to-offline (O2O) services based on location information. In the process of finding user locations in O2O services, BLE (Bluetooth Low Energy) beacons are widely used because the beacons are economical in many ways. The current BLE method does not specify the direction of user movement, but adding that information could enrich the user experience for various O2O services. This paper proposes a method that identifies the user movement direction through data analysis on data sets generated by a pair of BLE beacons. Also we demonstrate its implementation with examples of services that need the direction information of users in order to show the feasibility of the method proposed.

The work patterns in the organizations performing research and development projects consist of both administrative business with defined processes and knowledge-oriented research and development business with undefined or semidefined processes. This paper describes an enterprise portal model and its services aligned to research and development organization's work patterns. The proposed portal model is focused on constructing personalized workplaces providing knowledge-based services for research and development business, as well as business process management based services for administrative business. The further research will provide more concrete portal model and its applicability to research and development organization's business.

Seaweed aquaculture technologies have developed dramatically over the past 70 years mostly in Asia and more recently in Americas and Europe. However, there are still many challenges to overcome with respect to the science and to social acceptability. The challenges include the development of strains with thermo-tolerance, disease resistance, fast growth, high concentration of desired molecules, the reduction of fouling organisms and the development of more robust and cost efficient farm systems that can withstand storm events in offshore environments. It is also important to note that seaweed aquaculture provides ecosystem services, which improve conditions of the coastal waters for the benefit of other living organisms and the environment. The ecosystem services role of seaweed aquaculture and its economic value will also be quantitatively estimated in this review.

Before a contractor embarks on exporting its services, it needs to know if it is likely to succeed. This research developed two prediction models to help contractors in Singapore predict the number of projects (Y1) and the contract values (Y2) that they are likely to secure from overseas. Detailed characteristics of 60 contractors who export their services (exporters) were obtained from the database of registered contractors in Singapore. Multiple linear regression models were developed and tests showed that Y1 is a robust model. A contractor's chance of winning more overseas projects may be predicted by the number of projects it acted as a subcontractor; the variety of projects it undertakes; the total contract value in the domestic market; and the number of countries it exported its services to. It is recommended that contractors who are planning to export their services be flexible instead of adopt a focused policy of undertaking only one or two project types in a few selected countries.

As we go about our daily lives, people often collect surrounding information and adapt to the situation. Computer development trends show that one wants computers to work like human beings, i.e. computers can sense its context and adapt corresponding to context changes. To implement this expectation, a context aware service layer is needed. In this layer, sensors capture its environment and send this information to the service center. Considering received information as its context, the service center seeks the suitable operation according to the context. Tills paper presents a context aware service which is applied in controlling air-conditioner. The air-conditioner includes sensors which are installed at some special positions in a room. Each of these sensors gathers comfort-influenced information like temperature, humidity and sends them to air-conditioner. The air-conditioner adapts its operation to the environment according to the sensed information. To control the air-conditioner effectively, we use a genetic algorithm which is suitable in adaptation issues. The simulation shows that the room condition can be maintained at a comfortable level by using context-aware services in the operation of the air-conditioning system.

This paper is an overview of key elements of Korea National Open University's smart mobile learning system, and an attempt to evaluate its main services relative to the FRAME model and the Mobile Learning Development Model for distance learning in higher education. KNOU improved its system architecture to one based on xMOOC e-learning content delivery while also upgrading its PC-based online/mobile learning services to facilitate an easier and more convenient access to lectures and for better interactivity. From the users' viewpoint, the upgraded 'U-KNOU Campus' allows for a more integrated search capability coupled with better course recommendations and a customized notification service. Using the new system, the students can access not only the school- and peer-issued messages via online bulletin boards but also share information and pose questions to others including to the school faculty/officials and system administrators. Additionally, a new mobile payment method has been incorporated into the system so that the students can select and pay for additional courses from anywhere. In spite of these advances, the issue of device usability and content development remain; specifically U-KNOU Campus needs to improve its instructor-learner and learner-to-learner interactivity and mobile evaluation interface.
