In our modern society, the utilization of the advanced drone which is capable of performing variety of tasks has been gradually increasing. In this paper, we present an application, similar to the prototype "Skycall" that had been introduced in the MIT Senseable City. To assess this concept, we have implemented a prototype of drone-based pedestrian navigation depending on the Android smartphone. Our system is not only able to guide the user in a very complicated place, where buildings are compacted, but also to block unauthorized visitors from accessing the facilities. And we discuss some problems we found and suggest the direction to address them.

We intend to improve the sustainability of rural villages by investigating the element technologies and platforms necessary for building smart villages. There are so many investment smart city platforms and solutions in many cities. but there are relatively few investments in rural or small cities. This situation can not only increase the urban problem due to the increase of population to the city, but also deepen the digital gap of citizens. So far, studies on smart village have been investigated in fragments. We will examine the cases applied to smart village as a whole and study the open smart village platform that analyzes the overall data storage and management of the village after the smart village was finally established. First, we will look at the overseas trends of smart village and second, we will study the smart village platform that efficiently manages smart village through the technology necessary for smart village.

Fast developing digital technology is Having an enormous societal influence, creating a porous new world without boundaries. This phenomenon applies to a whole range of fields, including culture, politics and even our daily lives. Urban Street cannot be excluded from this world-transforming change. Digital technology is changing the physical structure, growing patterns, function and role of the Urban Street. As a result, Urban Street should now be freeing themselves from the old-world functionalism, which has been pursued uniformly under the names of rationality and efficiency. We have, then, to think about the culture of the Digital Urban Street,'that is, the digital life style, which is tangibly generated in the concrete city space, and which must be prepared for further digitalization. This paper argues that the street must be understood as a communications centre, because digital technology has created a new communications style. Also, this paper focuses on how the physical environment of Urban Street will evolve with regard to both function and appearance. In conclusion, studying the ubiquitous space, it also looks at how existing urban planning and space design should lead to the further development of Urban Street using digital technology, as well as to the role this technology will have in the future.

The 'Dinosaur Experience' exhibition at the Lasko exhibition hall hosted by Gwangmyeong city is gaining popularity. The purpose of this study is to analyze the elements of experience exhibition and interactive media experience exhibition and to grasp the preference of visitors. First, the theoretical review about interactive media and experience exhibition was made through literature data. Next, based on the Strategic Experience Module, we divided the experiential factors according to experiential value. As a result of the study, it was found that the participation rate of the visitors and the experience time were longer in the program containing many experience exhibition elements. Interactive media experience exhibited by many people have more value items. But it is not enough to understand the preference of visitors by the time spent by visitors. This study suggests that interactive media can be utilized for various experience exhibition.

With the advent of ubiquitous computing society, many advanced technologies have enabled wireless sensor networks which consist of small sensor nodes. However, the sensor nodes have limited computing resources such as small size memory, low battery life, short transmission range, and low computational capabilities. Thus, decreasing energy consumption is one of the most significant issues in wireless sensor networks. In addition, numerous applications for wireless sensor networks are recently spreading to various fields (health-care, surveillance, location tracking, unmanned monitoring, nuclear reactor control, crop harvesting control, u-city, building automation etc.). For many of them, supporting security functionalities is an indispensable feature. Especially in case wireless sensor networks should provide a sufficient variety of security functions, sensor nodes are required to have more powerful performance and more energy demanding features. In other words, simultaneously providing security features and saving energy faces a trade-off problem. This paper presents a novel energy-efficient security architecture in an IEEE 802.15.4-based wireless sensor network called the Hybrid Adaptive Security (HAS) framework in order to resolve the trade off issue between security and energy. Moreover, we present a performance analysis based on the experimental results and a real implementation model in order to verify the proposed approach.

In this paper, we discussed about the volume monitoring system of a landfill facility. We proposed the waste volume calculation method using the point cloud of the surface of three dimensional object by measurement of the point cloud by the three dimensional scanner, which is based upon the robot technique. This computes not only the quantity of waste volume for continuos monitoring but also it helps not only to predict the evaluation factor of the usable age of a landfill. facility. Furthermore, the measuring system of waste volume was applied to the landfill facility in Ansung city.
