The purpose of this study is to explore ways to nurture creative and fusion-type talents centered on ANT. In order to nurture creative and convergence-type talents centered on ANT, first, it is necessary to utilize Kao's Law in the network formation stage. Second, it is necessary to utilize the strong power of weak ties in the network formation stage. Third, in order to cause a stir in the stage of raising questions among the four stages of translation, the ability to ask questions must be developed. Fourth, education in various creative problem-solving techniques is needed to throw a stir. Fifth, in order to successfully intervene in the second stage of the four stages of translation, the stage of attracting attention, communication and critical thinking skills must be trained. Suggestions for follow-up research are: First, it is necessary to compare and analyze the four stages of translation and the stage of the creative problem-solving model presented by ANT. Second, it is expected that there will be follow-up studies that apply specific cases centering on ANT.

최근 우리나라에서 방송과 통신의 융합에 대한 연구가 활발하게 이루어지고 있다. 실제로 방송과 통신이 기술적으로 융합화되어 가고 있고, 방송통신위원회를 기반으로 각종 방송 통신 정책 및 제도들이 개정되어 운영되고 있다. 융합 환경의 핵심적인 특징은 네트워크가 현재보다 더 광범위한 서비스 제공을 위한 수단으로 이용될 수 있다는 것이지만 융합에 따른 불확실성, 즉 융합에 따른 취약성을 제거하지 않고서는 서비스의 안전성을 보장할 수 없다. 따라서, 방송 통신 융합의 불확실성을 제거하고 향상된 서비스를 제공하기 위하여 방송과 통신의 융합과 관련된 보안 취약점 분석 프로세스 개발이 요구된다. 이에 따라, 본 논문에서는 방송과 통신의 기반시스템이 융합화되는 과정에서 발생되는 취약성에 대한 문제점을 알아보고 이에 대한 취약점을 분석하기 위한 프로세스를 제시한다.

The international society under the internet technology have been declining boundaries of the global economy. After this step, a social revolution will be happen from the ubiquitous technology which fives objects intelligence to serve people. And then it is expected that every part of a city competitive power is defined by both in qualify and in quantify of the ubiquitous information unit in the future. On this score, now each nation is trying to set relative services and broadband networks to lead the ubiquitous industry. Therefore this paper analyzed about the progress and prospect of a local U-city plan in our nation Especially we propose a new city development model which use U-city and self-communication network to Improve a city competitive power.

The international society under the internet technology have been declining boundaries of the global economy. After this step, a social revolution will be happen from the ubiquitous technology which gives objects intelligence to serve people. And then it is expected that every part of a city competitive power is defined by both in quality and in quantity of the ubiquitous information unit in the future. On this score, now each nation is trying to set relative services and broadband networks to lead the ubiquitous industry. Therefore this paper analyzed about the progress and prospect of a local U-city plan in our nation. And than we propose a method of configurating broadband self-communication network on the base of cost and utilization Especially we propose a new city development model which use U-city and self-communication network to improve a city competitive power.

Although the performance of cameras is gradually improving now, there are noise in the acquired digital images from the camera, which acts as an obstacle to obtaining high-resolution images. Traditionally, a filtering method has been used for denoising, and a convolutional neural network (CNN), one of the deep learning techniques, has been showing better performance than traditional methods in the field of image denoising, but the details in images could be lost during the learning process. In this paper, we present a CNN for image denoising, which improves image details by learning the details of the image based on wavelet transform. The proposed network uses two subnetworks for detail enhancement and noise extraction. The experiment was conducted through Gaussian noise and real-world noise, we confirmed that our proposed method was able to solve the detail loss problem more effectively than conventional algorithms, and we verified that both objective quality evaluation and subjective quality comparison showed excellent results.

모바일 혁명으로 대변되는 제2의 인터넷혁명시대의 도래에 따라 방송통신산업에도 큰 변화가 나타나고 있다. 구글, 애플 등 플랫폼 사업자를 중심으로 생태계 경쟁이 심화되면서, SW 콘텐츠 개발자 등에게 새로운 성장기회가 형성되고 있고 정보의 생성 및 유통속도가 가속화되면서 클라우드, 빅데이터 등 신산업이 부상하고 있다. 또한, 인터넷 중심으로 방송통신망이 융합되면서 스마트TV 등 인터넷 동영상서비스가 확산되고, 방송시장 내에서도 유료방송서비스간 경쟁이 심화되고 있다. 스마트 생태계 구축경쟁과 인터넷 중심 융합으로 특징지워지는 새로운 방송통신 패러다임은 기존 방송통신산업구조와 규제체계의 전환을 촉구하고 있으며, 방송통신 융합을 촉진하고 방송통신산업을 육성하기 위해서는 C(콘텐츠)-P(플랫폼)-N(네트워크)-T(기기)를 아우르는 종합적인 접근이 요구되고 있다. 본 고에서는 우선 방송통신 분야의 정책환경 변화를 살펴본 후 네트워크 고도화, 방송통신 R&D, ICT 중소 벤처기업 육성, 방송통신콘텐츠산업 경쟁력 제고 등 방송통신 산업이 한 단계 더 도약하기 위해 필요한 주요 정책과제들을 살펴본다.

가상 및 증강현실(VR/AR), 원격 제어, 산업 자동화를 위한 실시간 애플리케이션이 증가함에 따라 무선 통신 네트워크의 처리량과 지연시간 성능이 중요해졌다. 이에 따라 Wi-Fi 8 에서는 초고신뢰 (Ultra-High Reliable, UHR)을 목표로 표준화가 진행 중이며 다수의 AP가 협력하여 데이터를 전송하는 다중 AP 협력 기법이 핵심 기술로 논의되고 있다. 하지만 기존의 다중 AP 협력 환경에서 협력 전송을 위한 제어 정보로 인한 간섭 증가와 OBSS(Overlapped Basic Service Set) 간섭 문제를 고려하지 못하고 있다. 따라서 본 논문에서는 효율적인 다중 AP 협력 전송을 위한 단순화된 채널 관리 방법(Simplified Channel Management Mechanism, SCMM)을 제안한다. 실험 결과에 따르면, SCMM 이 종래모델 대비 처리량은 평균 21.23% 증가했고, 지연시간은 평균 51.02% 감소했다.
