Image recognition technology is a technology that recognizes an image object by using the generated feature descriptor and generates object feature points and feature descriptors that can compensate for the shape of the object to be recognized based on artificial intelligence technology, environmental changes around the object, and the deterioration of recognition ability by object rotation. The purpose of the present invention is to implement a power management framework required to increase profits and minimize damage to livestock farmers by preventing accidents that may occur due to the improvement of efficiency of the use of livestock house power and overloading of electricity by integrating and managing a power fire management device installed for analyzing a complex environment of power consumption and fire occurrence in a smart safety livestock house, and to develop and disseminate a safe and optimized intelligent smart safety livestock house.

인터넷 가상화폐 거래소에 게시되는 공시를 분석하여 향후 게시된 공시가 가상화폐 가격에 줄 영향을 예측해보고자 한다. 과거 게시된 공시 데이터를 바탕으로 딥러닝을 이용해 영향치를 도출해낸다. 프로그램은 Python 언어로 작성하였으며, django 웹 프레임워크를 이용하여 결과치를 보여줄 수 있는 웹 사이트를 구현하였다. 또한 공시를 통합한 데이터를 이용하여 새로 게시되는 공시가 해당 가상화폐의 가격에 줄 예측치를 분석하였으며 해당 공시가 가상화폐의 가격에 어떻게 영향을 줄지 쉽게 판단할 수 없는 사용자들에게 도움을 줄 수 있을 것이다.

모든 도시가 발전하고 번창하기 위해서는 핵심기반시설의 재난 및 안전이 선제적으로 확보되어야 한다. 본 논문에서는 환경핵심기반시설을 중심으로 지역사회가 지속 가능한 녹색도시로 거듭나기 위해 재난준비태세 증진에 실제 활용 가능한 위험지도를 드론에 장착한 LiDAR 센서를 통해 수집한 고도 데이터를 바탕으로 제작하였다. 나아가 지진과 같은 재난 발생 시 시설에서부터 확산하는 관리 오염물의 경로 및 범위를 시범 모의하여, 기능 연속성 계획 및 재난대응 가이드와 연계를 하는 방안을 제시함으로 지자체 중심의 통합적 지역사회의 노력이 발현될 수 있도록 기초적 연구를 진행하고, 전략적 활성화 방안을 제시하였다. 본 연구는 끊임없는 성장과 거듭되는 개발로 인해 변화하는 도시의 형상에 따라 리스크를 최신화하여 대응력을 높이고, 이해관계자들에게 시각화된 재난 범위 모의를 제시함으로써 지역사회와 지자체 역량에 따른 협력적 재난대응태세에 필요한 프레임워크 도출 및 계획수립을 가능하게 한다는 점에서 큰 의의를 지닌다. 또한, 각 영역별 전문가들의 자문을 통하여 본 논문에서 제시된 확산 모의의 방법론이 타당함을 확인하였다. 무엇보다 모호한 "가능한 신속한 자원관리"와 같은 추상적인 대응계획이 아닌, 객관적인 재난자원관리계획을 수립할 수 있게 함으로써 추후 국가적 재난 및 안전역량을 계량화시킬 수 있을 것으로 사료된다.

In this paper, we propose a balanced approach to AI regulation, focused on harnessing the potential benefits of artificial intelligence while upholding fairness and ethical responsibility. With the increasing integration of AI systems into daily life, it is essential to develop regulations that prevent harmful biases and the unfair disadvantage of certain demographics. Our approach involves analyzing regulatory frameworks and case studies in AI applications to ensure responsible development and application. We aim to contribute to ongoing discussions around AI regulation, helping to establish policies that balance innovation with fairness, thereby driving economic progress and societal advancement in the age of artificial intelligence.

This paper aims to integrate the previous models about mean object transfer latency in one framework and analyze the result through the computational experience. The analytical object transfer latency model assumes the multiple packet losses and the Internet of Things(IoT) environment including multi-hop wireless network, where fast re-transmission is not possible due to small window. The model also considers the initial congestion window size and the multiple packet loss in one congestion window. Performance evaluation shows that the lower and upper bounds of the mean object transfer latency are almost the same when both transfer object size and packet loss rate are small. However, as packet loss rate increases, the size of the initial congestion window and the round-trip time affect the upper and lower bounds of the mean object transfer latency.

Avionics System Integration Laboratory is the integrated test environment for integration and verification of avionics systems. When real equipment can not be used in the laboratory for various reasons, software models should be needed. Because there hasn't been any standardized method for the models so that it is difficult to reuse the developed models, the need for a framework to develop the avionics software models was emerged. We adopted DEVS(discrete event system specification) formalism as the standardized modeling method for the avionics software models. Due to DEVS formalism is based on event-driven algorithm, it doesn't accord a legacy system which has sequential and periodic algorithms. In this paper, we propose real-time event-driven modeling and simulation method for SIL to overcome these restrictions and to maximize reusability of avionics models through the analysis of the characteristics and the limitations of avionics models.

As major industries become information -centered, business transactions and information -sharing processes are being computerized and automated, which ultimately re-defines electronic commercial transactions in a broader context. Business documents are the basic tools for corporate transactions. The use of business documents in electronic commercial transactions has increased markedly and this sphere is rapidly being extended to include information sharing between companies. XML(extensible Markup Language) was selected as the focus for this thesis. XML can help to make a complicated and data-rich document easy to share. The thesis proposes a business XML document editing system, comprised of a style document editor for business XM document structure, business documentation, and business document presentation, along with a business document transformation system which makes a transformation possible regardless of platform or using various corporate document standards.

In this paper, we propose the framework of a visual language named VIOLA(VIsual Object-oriented Language for Multimedia Applications), which is developed for web authoring. VIOLA supports the user to construct HTML documents and CGI programs even if he/she doesn't know exact HTML tags and CGI programming. VIOLA, a user interface building part and a programming logic building part are combined by the data-flow model. the user interface building part provides direct manipulation and a WSIKWYG interface, and the program logic building part provides more intuitive interface by using predefined classes and the data-flow model. thus, even a novice user can construct sophisticated applications by simply moving or clicking the mouse. several classes which generate CGI codes are predefined, and they are represented with highly abstracted visual components, By reusing predefined classes, CGI codes are automatically generated. In VIOLA, all major steps in builidng generated wit HTML documents and Java CGI programs.

This paper describes UPnP AV System which provides various multimedia services in home network composed of diverse multimedia devices. It is difficult to build home network where various multimedia services can be provided because there are a lot of difference devices, platforms, and network technologies. However, UPnP middleware can make up multimedia service environment in that home network. Therefore this paper describes how the multimedia service environment is built with UPnP middleware. We analyze and modify MediaServer, MediaRenderer, and Control Point, which these are the components of UPnP AV archtecture. Additionally we provide some efficient GUI to use different kind of multimedia in any place of home networks. We propose UPnP AV Framework of playback module that consist of MediaServer providing contents, MediaRenderer using contents, and Control Point providing GUI. Especially, MediaRenderer and Control Point are integrated in set-top.
