본 논문에서는 Microsoft Visual Studio의 Bot Builder SDK Template, Bot Emulator, KaKao Map 서비스를 활용하여 제주도 여행지를 추천하는 챗봇을 구현한다. 이 챗봇은 제주도 여행을 계획하고 있는 사용자에게 적절한 서비스를 제공하는 챗봇이다. 사용자에게 여행지 관련 테마를 제시하고, 사용자는 챗봇이 제시한 선택지 중 자신이 가장 선호하는 선택지를 선택한다. 사용자가 선택지를 결정하면 이를 바탕으로 챗봇 데이터베이스에 있는 적절한 여행지를 추천한다. 사용자가 테마를 고르지 않고 모든 데이터를 보고자 하는 경우 목록보기를 선택하여 챗봇이 가진 모든 여행지 목록을 볼 수 있다. 이 과정을 통해 사용자는 자신이 원하는 분야의 제주도의 적절한 여행지를 추천받을 수 있다.

The DVR system supports multiple cameras and should be able to receive images at 30 frames per channel in real time. Thus, The system is using Full-HD-grade Multiplexer and Hardware compression codec. In this paper, Describing the design and implementation for the 4-channel Full-HD-grade PC-based DVR using FPGA and GPU inside CPU without Multiplexer and Hardware codec. The existing DVR system for Full-HD-grade has drawbacks to acquire images of about only 20 frames per channel in real time. The system to acquire images of multiple channel in real time was designed using FPGA. The software for the system was implemented using Intel Media SDK. At the result of performance evaluation, It was satisfied all for the required conditions. The practicality of the system was confirmed as implementation the system without using hardware compression.

Retargetability is typically achieved by providing target machine information, ADL, as input. The ADL are used to specify processor and memory architectures and generate software toolkit including compiler, simulator, etc. Simulator are critical components of the exploration and software design toolkit for the system designer. They can be used to perform diverse tasks such as verifying the functionality and/or timing behavior of the system, and generating quantitative measurements(e.g., power energy consumption) which can be used to aid the design process. In this paper, we generate the energy consumption estimation simulator through ADL. For this goal, firstly, we describes the energy consumption estimation and monitoring informations on the ADL based on EXPRESSION. Secondly, we generate the energy estimation and monitoring simulation library and then constructs the simulator, RenergySim. Lastly, we represent the energy estimations results for MIPS R4000 ADL description. From this subjects, we contribute to the efficient architecture developments and prompt SDK generation through programmable experiments in the field of mobile software development.

This study was to develope a vibrotactile display system using windows media player from digital audio signal. WMPlayer10SDK system which was plug-in tool by microsoft windows media player provided its video and audio signal information. The audio signal was tried to be change into vibrotactile display. Audio signal had 4 sections such as 8bit, 16bit, 24bit, and 32bit. Each section was computed its frequency and vibrato scale. And data was transferred to 38400bps network port(COM1) for vibration. Using this system was able to develop the music suit which presented tactile feeling of music beyond sound. Therefore, it may provide cross modal technology for fusion technology of human senses.

Apple recently announced a new policy about software development kit that banned the use of tools that convert apps built on other platforms into iPhone apps. Therefore, Adobe cannot develop their software to AppStore that inquire to the Department of Justice and the Federal Trade Commission about antitrust actions. Someone argue that Apple try to exclusive smartphone market such as the Microsoft antitrust lawsuit in 1998, but this case is essentially different. First, it need to define Apple's software development kit for iPhone and iPad is whether antitrust or not. Because of the characteristics of two-sided market in Smartphone Apple's iPhone cannot monopoly in cellphone or smartphone market, but it can be an antitrust in application store market. However, Apple re-announced new software development kit policy that shows positive results. Instead of hastily intervened regulatory agencies, the DOJ or the FTC, it is quite desirable that watching the interaction between companies that whether market failures or not and if it's harmful for consumer's benefit. Adobe attack Apple to advocate consumers and developers freedom of choice, but the most important thing is conclusion based on a comprehensive analysis need to objective point of view that Apple do whether antitrust act or not and damage to developers and consumers who are both side of platform.

Multi-rotor UAVs are utilized in various fields because of the advantages such that a hovering capability such as helicopters, a simple structure and a relatively high thrust. Recently, AR.Drone manufactured by Parrot is easily operated by beginner due to its internal stabilization loop in the on-board computer and it can be easily applied on various researches for the multi-rotor UAVs by providing an SDK(Software Development Kit). Further this platform can be suitably used for application to swarm flight since it is low cost and relatively small. Therefore, in this paper, we introduce the development process of the controller for indoor swarm flight by using the AR.Drone.

Android is the OS for mobile phones created by Google. Android has changed the situations of mobile developing community, and currently many of mobile programs based on the android platform are designed. In this paper, android platform based traffic information system by using LBS is proposed and developed. The main contributions and features of the proposed system are as follows. First, no space constraints as mobile based traffic information system. Second, basic information services as well as telephone service. direct homepage service. Third, user oriented suitable program that can be made by users themselves. The performance evaluation of the developed system is performed by using AVD (Android Virture Device) for Android SDK 1.5.

This Audio-Visual Interactive Installation is composed of a video projection of a video Projection and digital Interface technology combining with the viewer's voice recognition. The Viewer can interact with the computer generated moving images growing on the screen by blowing his/her breathing or making sound. This symbiotic audio and visual installation environment allows the viewers to experience an illusionistic spacephysically as well as psychologically. The main programming technologies used to generate moving water waves which can interact with the viewer in this installation are visual C++ and DirectX SDK For making water waves, full-3D rendering technology and particle system were used.

Recently, systematic research on the brain has been conducted and BCI(Brain -Computer Interface) technology applying electroencephalogram has been actively researched. Especially, serious game technology using BCI device has been the subject of interest. This paper develops a "twosome collaboration dance game," which is a serious game that takes advantage of NeuroSky's SDK(System Development Kit) and helps developing the spirit of team work and sociality based on attention and meditation, unlike existing single player games. We expect that this game will help to visualize brain functions of people and to cure ADHD children and the elderly people with MCI(Mild Cognitive Disorder). It is also expected to play a role of social catalyst to the game culture of the adolescent.
