Wireless sensor networks (WSN) are becoming widely used in collecting and sensing information in different fields such as in the medical area, smart phone industry and military environment. The main concern here is reducing the power consumption because it effects in the lifetime of wireless sensor during commutation because it may be work in some environment like sensor in the battlefields where is not easy to change the battery for a node and that may decrease the efficiency of that node and that may affect the network traffic may be interrupted because one or more nodes stop working. In this paper we implement, simulate, and investigate S-MAC protocol with mobility support and show the sequence of events the sender and receiver go through. We tested some parameters and their impacts of on the performance including System throughput, number of packets successfully delivered per second, packet delay, average packet delay before successful transmission.

The environment of using digital devices has been developed day by day, as mobile communication network has been fast and smart phone and tablet PC have been spread. When the environment changing, the contents consumers prefer have been changing too. The Webtoon became the representative contents of 'Snack culture'. The webtoon has led the growth of cartoon market for years recently instead of the slow comics growth. And it places its elf as contents on a firm basis, as it has been adapted to another genre such as Pay, Flm, TV Drama. Now it's expected to be an extgeneration contents that will lead Han-ryu(Korean wave). Though the webtoon has important and strong presence, there is no digital archive for collecting and preserving the webtoon, Korean Cartoon Contents Agency started making 'webtoon archive', but the groundwork and the study on the webtoon that represents digital culture contents are not enough a lot. In this study, the cases on digital archiving of culture contents in Korea are researched, and the direction on webtoon archiving that has just started is also discussed. The Archiving of webtoon that can't be seperated from digital contents is connected with archiving of digital culture contents in direction where they should be headed to.

Under the penetration of smartphones equipped with a variety of features grows globally, the efficient using of a variety of functions of smartphones has been increased. In accordance with this trend, a lot of researches on the remote control method using the smart phone for consumer products in home networks. Input methods of the current smpartphoes are typically button-based inputs through touching. The button input methods are inconvenient for people who are not familiar touch. Therefore, the researches on the different input schemes to replace the touch methods are required. In this paper, we propose a gesture based input method to replace the touch-sensitive input that of the existing smartphone applications, and a way to apply it to home networks. The proposed method uses three-axis acceleration sensor which is built into smatphones, and it also defines six kinds of gestures patterns that may be applied to home network systems by measuring the recognition rates.

The controversy about the burger button triggered in 2013 is that it is difficult to know what the hamburger button itself means and that it is difficult to predict what will happen when the button is clicked, Could. This controversy was found to be fundamentally out of touch, and it could be seen that it caused conflict with Apple's navigation structure with iOS. Therefore, in the case of Apple, it is often used in the form of a tab at the bottom instead of using the slide menu, but it is preferable to be used for the purpose of the hamburger button. I've looked through a variety of documents and found that the amount of content you want to offer on your app or the web is large, and there are five or more categories. And if a sub-category needs to exist in the main category like a large shopping mall, the hamburger button could provide the best UI. Apps and webs that can be curated, such as news and pinterest, are better used to enhance the search filter than to place a hamburger button, and for apps or the web that has a longer amount of content on a page Scrolling was available as an alternative to the burger button. In other words, depending on the amount of content to be provided, it is possible to decide whether to use the hamburger menu from the time of designing the information architecture.

In the era of information society, IT industry has been developed very much. New technology has made appearance in citizens' lives. IOT (Internet of Things) has grown up the most rapidly in IT industry. Kevin Ashiton, MIT specialist, said, "Loading of FRIS and other sensors shall build Internet of things." Internet of things is said to let things have sensor and communication module and to exchange information and communicate each other. In this study, Internet of things has been applied to flowerpot to build automatic flowerpot control system that turns fan ON and supplies water depending upon temperature and moisture. Users are difficult to cognize temperature and humidity of flower pot correctly. In this study, an experiment obtained correct value of temperature and humidity to build control system. At the performance test of flower pot, commands turned ON depending upon temperature and humidity. Control system should be added to control water supply quantity and time objectively according to servo motor control. Purpose of further study was to control flower pot by remote system in connection with smart phone application. An application control can make not only temperature and humidity statistics but also server depending upon users' needs to turn fan ON and take actions and to control flower pot.

The christian communities have been maintained and spreaded based on the great foundation of the holy bible. The printing and publishing technology made the holy bible popular at the end of the middle age. Namely, because of this remarkable development, the Bible have been became the best seller for centuries. Since the smart phone users have been growing, the number of people use the Bible Application have been increased. In this circumstance, the interface becomes a crucial element in the Age of Digital Media. Thus, developers have to regard the user's convenient. The user's characteristic is the important point to develop applications. This study is focusing on a particular using of the Bible, and how the using characteristic affects on application's UI. For this study, five bible applications reflecting particular using characteristics are chosen and compared in terms of function of services and elements of UI. Form this comparison and analysis, this study deduces the pattern of UI considering particular using characteristics such as patterns of reading, recording, sharing, and searching the bible. This study would be useful data for publications formed into applications and setting the UI which reflected the using characteristics be better user-centered.
