The changing pattern of living and communication, combined with wireless technologies has given rise to more fluidity between spaces and relationships. Despite this, the way we use technology and the qualities of product and service are limited. For example, ON or OFF is like BLACK or WHITE, it presents a harsh distinction This severity in definition can make me uncomfortable when using products. The aim of this project is to improve the use of a product's functions and Qualities. As an example, the switch button has limited the possible interaction of a product. even each function is different. 1 intend this study is to imbue the switch with a greater freedom of interpretation. What will happen If I create a journey in between on and off\ulcorner For instance, time, pattern, state, rhythm and so on are analogue properties of a switch. The playful, spontaneous, and enjoyable behaviour of a switch will be able to bring other qualities of function and service. The switch will then be able to be an object with more human qualities, not simply an on and off button.

The Internet of Things (IoT) era, in which all items used in daily life are equipped with a network connection function, and they are closely linked to increase the convenience of life and work, has opened wide. Robots also need to develop according to the IoT environment. A use of new type of evolved fuzzy machine (EFM) for generating legged robot trajectory in IoT enviornmentms is discussed in this paper. Fuzzy system has been widely used for describing nonlinear systems. In fuzzy system, determination of antecedent and consequent structures of fuzzy model has been one of the most important problems. EFM is described which carries out evolving antecedent and consequent structure of fuzzy system for legged robot. To generate the robot trajectory, parameters of each structure in the fuzzy system are tuned automatically by the EFM. The results demonstrate the performance of the proposed approach for the legged robot.

The Internet of things (IoT) is the extension of Internet connectivity into various devices and everyday objects. Embedded with electronics, Internet connectivity and other forms of hardware. The IoT poses significant risk to the entire digital ecosystem. This is because so many of these devices are designed without a built-in security system to keep them from being hijacked by hackers. This paper proposed a mutual authentication protocol for IoT Devices using symmetric-key algorithm. The proposed protocol use symmetric key cryptographic algorithm to securely encrypt data on radio channel. In addition, the secret key used for encryption is random number of devices that improves security by using variable secret keys. The proposed protocol blocked attacker and enabled legal deives to communicate because only authenticated devices transmit data by a mutual authentication protocol. Finally, our scheme is safe for attacks such as eavesdropping attack, location tracking, replay attack, spoofing attack and denial of service attack and we confirmed the safety by attack scenario.

This study was conducted with the elderly who used a senior welfare center to help their health improvement. After the status of body composition, senior fitness, life habits, and nutrition levels in the elderly were investigated, a wellness health improvement program was conducted for 12 weeks. Effects before and after the program were examined. The following conclusions were drawn. 1. For the changes of body composition by age associated with sex, while elderly men had a significant difference in BMI, elderly women had a significant difference in B.M.I and body fat percentage. 2. For the changes of senior fitness by age associated with sex, while elderly men had a significant difference in lower body muscle, upper body muscle, upper body flexibility, and transformed general endurance, elderly women had a significant difference in lower body muscle and upper body muscle. 3. For the changes of life habits and nutrition levels by age associated with sex, while elderly men had a significant difference in diet habits and exercise habits, elderly women had a significant difference in exercise habits, stress relief habits, and total nutrition level. Based on the findings, the elderly's participation in the wellness improvement program can enhance lower body muscle which is a risk factor of daily activities and fall and increase upper body muscle which is good to carry and move everyday objects. In addition, it may play a positive role in improving diet habits and changing stress relief and exercise habits, resulting in better health and quality of life of the elderly.

The social statistic was used to top 250 Korean and Japanese YouTube channels based on the number of subscribers examine its channel type (private/corporations/others), distribution of contents and private YouTube channels' date of registration. The channel examination was also used to provide practical hint to create new Youtube contents. According to the statistics, Korean channels were mainly managed by K-Culture related companies for the promotional purpose, whereas Japanese channels were mainly managed by individuals with a variety of contents. It is presumed that Japanese individuals have been engaged in creating individual video content since the early period through video uploading platforms other than YouTube such as Niconico Douga. Since the expansion of the YouTube market will continue, it is important not only to reinforce corporations' marketing on YouTube but also to promote the uniqueness and the diversity of YouTube content for the individuals to improve the economical, sentimental, and informational contents in order to create socially effective personal contents that can be competitive in the global market.

Researches on particle physics have benefited our everyday life in many aspects. They have tested the safety of the objects we use everyday, conducted experiments to examine harmful environments to man, and treated diseases. Despite the usefulness of particle physics in a range of fields, however, it's difficult to conduct researches and experiments directly. But the advancements in the computer industry have allowed for experiments of particle physics in virtual simulations. One of the foremost simulation libraries for particle physics that have been researched actively these days, Geant4 has been put to diverse uses in particle physics. This study designed GUI so that physicists, who were not good at programming, could use a simulation library faster, more accurately, and more conveniently. It also developed the Geant4Editor, a simulation automation framework. The advantages of the Geant4Editor include automatic generations of essential classes in a simulation using Geant4 libraries and real-time reflection of user demands in a simulation. It also allows for efficient management of resources(user-created data) through the Data Manager.

I searched the recent murder cases for other criminal methods of homicides the monthly statistics of the local police agencies of the whole country, I found that there are many criminal cases where knives were used. Based on this finding, I decided to conduct my survey about kitchen knives. The statistics indicated more than five hundread male and female adults were reported to have committed murders. Of the 500 people, 21 used a kitchen knife to commit murder. This study showed that when people have a conflict, the kitchen knife is as a tool that can be easily changed into a weapon. If the points of the knife is round, more homicides could be avoided. If regulations were established, as we have with dagger when producing, selling or purchasing, I would assume that the number of the crimes with knives will be remarkably diminished. It is our responsibility to create a bill concerning regulatory standards in understanding the dangers of kitchen knives. We must immediately participate in active publicity campaigns.
