The society increased interest because the scale and size of disaster is getting gradually large. However, urban hazard mitigation management of existing system had many problems about prompt hazard mitigation (prevention, provision, confrontation, restoration) in the event of disaster. For these reasons, this paper presents ubiquitous urban hazard mitigation management system of new ideas which are fusion ubiquitous technology and urban hazard mitigation management system to solve the existing system problems.

Microgrid is a convenient, reliable, and eco-friendly approach for the integration of Distributed Generation (DG) sources into the utility power systems. To date, AC microgrids have been the most common architecture, but DC microgrids are gaining an increasing interest owing to the provision of numerous benefits in comparison with AC ones. These benefits encompass higher reliability, power quality and transmission capacity, non-complex control as well as direct connection to some DG sources, loads and Energy Storage Systems (ESSs). In this paper, main challenges and available approaches for the protection of AC and DC microgrids are discussed. After description, analysis and classification of the existing schemes, some research directions including coordination between AC and DC protective devices as well as development of combined control and protection schemes for the realization of future hybrid AC/DC microgrids are pointed out.

Bioinformatics service is very new and emerging in market that provides information such as whether or not occurrence of a particular disease through the base of DNA(Deoxyribonucleic Acid) & RNA(Ribo Nucleic Acid) sequence analysis. Recently, interest growing rapidly in utilization of the industrial purpose, but provision of commercialization like pricing and service packaging is not enough to go to market. For go-to-market, firstly refine the services and perform cost calculation of services in cost-plus method then estimate consumer utility by conducting conjoint analysis. Collectively, with cost and consumer utility result, optimal service price can be calculated.

Immunosensors are of great interest because of their potential utility as specific, simple, label-free, direct detection means and provision of reduction in size, cost and time of analysis comparing with conventional immunoassay. In the last two decades, many reports have been published on the use of immunosensors for a wide range of applications to clinical diagnostics, pharmaceutical chemistry, environmental monitoring, biotechnology and food industries. There are also numerous transduction techniques developed such as electrochemical techniques, piezoelectric crystal, and surface plasmon resonance receiving much attention for the direct monitoring of immune reactions at solid surfaces. In this article, the principles, characteristics, structures, fonctions and clinical applications of immunosensors were reviewed

Recently, due to decrease hardware prices and the development of technology, analog signage has been changing to digital signage for providing content such as advertisements, videos. Furthermore, in order to provide advertisements and contents to users more effectively, technical researches are being conducted in various industries. In addition, including digital signage that uses displays, it can be seen that it provides advertisements and contents using diverse devices such as LED signage, smart pads, and smart phones. However, most digital signage is installed in one place to provide contents and provides interactivity through simple events such as manual content provision or touch. So, in this paper, we suggest a new object detection algorithm based on an adjacent frames based image correction algorithm for interactive building signage.

The interest in on-line services has increased during the last couple of years and there are now several models developed to better understand how customers evaluate e-service quality. In this empirical study we combine the use of the theories of attractive quality and technology readiness so as to explain customer experiences of e-services. A survey was conducted with 188 students at three universities in Sweden, asking how they assess an e-service that enables one to reserve and buy cinema tickets on-line. The main contribution of the study is its provision of evidence on how to interpret and improve customer satisfaction when designing e-services. Our belief is that an organization can gain a clearer grasp of how customer satisfaction is created with an e-service by taking into account customers' experiences with new technology.

Performed was a survey to find the level of interest on passenger services using IT and smart sensor technology in connection with High Speed Train development in Korea. The survey respondents were sampled from the KTX passengers, KTX crews, Korail employees, IT or sensor experts, and rolling stock experts. The results of the survey were categorized as importance, urgency/necessity, importance vs urgency/necessity, improvement measure, preferable activities based on the trip length, and inconveniencies. By analyzing the results, service items that can be implemented to the High Speed Train were recognized. The results showed that a passenger tends to expect to have his/her comfort and convenience, an attendant safety and serviceability, a Korail employee information provision and serviceability, an IT/sensor expert technological implementation done, and a rolling stock expert implementation done in practical level.

Although virtual reality technology may not be deemed as having a satisfactory quality for all users, it tends to incite interest because of the expectation that the technology can allow one to experience something that they may never experience in real life. The most important aspect of this indirect experience is the provision of immersive 3D audio and video, which interacts naturally with every action of the user. The immersive audio faithfully reproduces an acoustic scene in a space corresponding to the position and movement of the listener, and this technology is also called spatial audio. In this paper, we briefly introduce the trend of spatial audio technology in view of acquisition, analysis, reproduction, and the concept of MPEG-I audio standard technology, which is being promoted for spatial audio services.

There is a growing interest in ethical consumption, and consumers are demanding high levels of CSR for their companies. Transparent provision of corporate information among various areas of CSR is also an important topic in the recent consumption situation. In the global fashion industry, it is also a type of radical corporate transparency and ethical management, led by several advanced startups such as Everlane. As a result, the production process is being disclosed. This study empirically analyzes the influence of this fashion product process transparency on the consumer evaluation of the company. According to a survey of 200 Korean respondents, the transparency of the presented fashion firms had a positive effect on corporate trust and purchase intention. It was confirmed that it has. On the other hand, consumer involvement, which has been discussed as an important personal attribute in the associated consumption environment, has no significant moderating effect. In other words, consumers' subjective corporate ethics involvement did not have a significant influence on their corporate transparency evaluation.

Voice and speech therapy can be performed in various ways depending on the situation, although it is generally performed in a face-to-face manner. Telepractice refers to the provision of specialized voice and speech therapy by speech-language pathologists for assessment, therapy, and counseling by applying telecommunication technology from a remote location. Recently, due to the pandemic situation and the active use of non-face-to-face platforms, interest in telepractice of voice and speech therapy has increased. Moreover, a growing body of literature has been advocating its clinical usefulness and non-inferiority to traditional face-to-face intervention. In this review, the existing discussions, guidelines, and preliminary studies on non-face-toface voice and speech therapy were summarized, and recommendations on the tools for telepractice were provided.
