It will be a word "SMART" if we will select a word which used the most popularly among the all medias. We use products included a word "smart" such as smart phone, smart TV, smart grid, smart key. These products were made by "smart technology". We know that our society is evolution to IT conversions. There are examples such as smart car, smart home, smart learning or education. Therefore, we are described trends and future of products including smart technologies.

Special applications designed for smart phone, so called "Apps" are rapidly emerging as unique and effective sources of environmental monitoring tools. Using the advantages of Information and Communication Technology (ICT), this paper propose an application that provides Indoor Gas Monitoring System. In this paper, use four wireless gas sensor modules to acquire sensors data wirelessly coupled with the advantages of existing portable smart device based on Android platform to display the real-time data from the sensor modules. Additionally, this paper adapts a simple gas classification algorithm to inform in-door Gas for users real-time based.

Recently, As smart phone offers rather superior functionality and interface than normal phone, the number of user increase rapidly. for the convenience of user, there are so many case of customize the system. Simultaneously a number of smart phones which vulnerable to security increase Exponentially. The number of malware which targets smartphone increases Annually, namely Threats have intensified. In this thesis, we suggest the Techniques and countermeasures of the vulnerability which targets aviation communication system by Smart-phone RF module with frequency modulation.

In this paper, we propose a new approach to intelligent control based on fuzzy logic for work efficiency improvement of smart factory by the applicaion of ariticulated robot. The intelligent control that is applied to the working process by the joint of robotic manipulator is the main focus to improve a work efficiency for implimentation of smart factory in general manufacturing process. In this study, we propose a new method of a fuzzy model and then develop a nonlinear relationship between interaction forces and manipulator position using a fuzzy model. The reliability of the proposed control method is illustrated by simulation and experiments.

This study aimed to investigate the convergence relationship between kinesiophobia and fear of falling in patients with stroke. A total of 113 patients with stroke participated in this study. Participants underwent inpatient rehabilitation and completed surveys with three different questionnaires including the fall efficacy scale (FES), translated Tampa Scale for Kinesiophobia 13 (TSK-13), and activity-specific balance confidence scale (ABC). TSK-13 and FES showed weak negative correlation (r=-0.226), and TSK-13 and ABC showed moderate negative correlation (r=-0.300). FES had a very strong positive relationship compared with ABC (r=0.838). Faller showed significantly low FES and ABC scores compared with non-faller (p<0.05). These results present that patients with stroke had mild kinesiophobia, and kinesiophobia is related to fear of falling. It is necessary to evaluate kinesiophobia in stroke rehabilitation.

Augmented reality smart-glass enables healthcare providers to use patient and their care related information without interference of workflow. In addition, augmented reality smart-glass simulation had advantages in improving competency via remote collaboration and real-time information sharing. This study investigated perception and attitude regarding augmented reality smart glass based healthcare simulation on three different groups of healthcare major students, computer major students, developers and faculties. Using convenience sampling method, data were obtained from 95 participants and statistical analysis were performed using SPSS 25.0. Developer and faculty group showed the highest scores, followed by healthcare major students. There was the high expectation on augmented reality smart-glass for skill acquisition and the high performance and big screen were essential features of device. The findings of this study revealed that differences between healthcare and computer major students exist and strategies to reduce those gaps are required to adopt augmented reality smart glass in healthcare settings.

Liquid filling machines are frequently used in packaging fields; however, there exists a problem in precisely measuring the quantity of the liquid. In the case where the liquid filling machine is not properly metered, there may be issues, such as the fluid exceeding the capacity or chemicals being exposed outside. In this paper, we propose a smart injection nozzle device that can solve the issues stated above. The proposed smart injection nozzle can raise the nozzle according to the water level to remove bubbles and inject the accurate amount of fluid. In addition, the efficiency of the logistics process is enhanced by the smart QR code. Through experiments using the developed smart injection nozzle device, we have noticed that the accuracy of injection capacity, nozzle position, reaction time and building data exceeded the target value. Therefore, it expected that this machine will give more production and save a lot of manpower for packaging industry.
