The drone is an unmanned aerial vehicle which has no human pilot. Drones can be classified into military drones, commercial drones, and personal drones by usage. Also, drones can be classified from large-sized to nano-sized drone by size and autonomous, remote controlled drone by control type. Especially, military drones can be classified into low-altitude drones, medium-altitude, and high-altitude drones by altitude. Recently, the drone industry is one of the fast growing industries in the world. As drone technologies have become more advanced and cost-effective, Korean government has set its goal to become a top-level country in drone business. However, the government's strict regulation for drone operations is one of the biggest hurdles for the development of the related technologies in Korea and other countries. For example, critical problems for drone delivery can be classified into technical issues and institutional issues. Technical issues include durability, conditional awareness, grasp and release mechanisms, collision avoidance systems, drone operating system. Institutional issues include pilot and operator licensing, privacy rules, noise guidelines, security rules, education for drone police. This study analyzes the trends of the drone industry from the viewpoint of technology and regulation. Also, we define the business areas of drone utilization. Especially, the drone business types or models for public sector are proposed. Drone services or functions promoting public interests need to be aligned with the business reference model of Korean government. To define ten types of drone uses for public sector, we combine the business types of government with the future uses of drones that are proposed by futurists and business analysts. Future uses of drones can be divided into three sectors or services. First, drone services for public or military sectors include early warning systems, emergency services, news reporting, police drones, library drones, healthcare drones, travel drones. Second, drone services for commercial or industrial services include parcel delivery drones, gaming drones, sporting drones, farming and agriculture drones, ranching drones, robotic arm drones. Third, drone services for household sector include smart home drones.

In this paper, we describe VLSI design and performance evaluation of OCB-AES crytographic algorithm that simulataneously provides privacy and authenticity. The OCB-AES crytographic algorithm sovles the problems such as long operation time and large hardware of conventional crytographic system, because the conventional system must implement the privancy and authenticity sequentially with seqarated algorithms and hardware. The OCB-AES processor with area-efficient modular offset generator and tag generator is designed using IDEC Samsung 0.35um standard cell library and consists of about 55,700 gates. Its cipher rate is about 930Mbps and the number of clock cycles needed to generate the 128-bit tags for authenticity and integrity is (m+2)${\times}$(Nr+1), where m and Nr represent the number of block for message and number of rounds for AES encryption, respectively. The OCB-AES processor can be applicable to soft cryptographic IP of IEEE 802.11i wireless LAN and Mobile SoC.

The Internet is now an integral part of the everyday lives of a majority of people. They are demanding web sites that offer credible information - Just as much as they want sites that are easy to navigate. But the online reality today is that few Internet users say they can trust the web sites that have products for sale or the sites that offer advice about which products and services to buy. Users want the web sites they visit to provide clear information to allow them to judge the site's credibility. Users want to know who runs the site; how to reach those people; the site's privacy policy; and how the site deals with mistakes. In the eyes of users all sites ate not equal. Users have different credibility standards for different types of sites. For news and information sites users want advertising clearly labeled as advertising. And users want the site to provide a list of the editors responsible for the site's contents, including the editor's email address. For e-commerce sites, user expectations and demands are just about as high as they can be. They say that it is very important that these sites provide specific, accurate information about the site's policies and practices.

Recently, according to demands for a mobility right of people with disabilities, the use of powered mobility device has been rapidly increased and recharging facilities have been set up in many places of country. But the standards for the installation and management of the facilities are not clear and many problems are brought up in operating the facilities. Therefore, regulations and realities of recharging facilities were investigated and the user survey was progressed. On the basis of the research results, a rational and efficient installation and management plan was drawn up. The plan suggests that the recharging facilities should be installed in a building managed by government and many kinds of public building like library, theater, sports facilities, department store, museum, etc. Further, the recharging facilities should secure independent place which have specified area for protecting of privacy and provide some amenities for people with disabilities to enhance the conveniences.
