The Internet of Things, the core of the Fourth Industrial Revolution, is growing by incorporating various technologies into various fields. Among them, smart home systems that apply IoT technology to home environments are being actively studied. The home hub market, a means of communication for smart homes, is also developing at the same time. As the home hub market develops, security threats are also increasing accordingly. In this paper, 'Smart Home Mirror' is implemented by combining mirror and IoT technologies so that users can use them to communicate with smart home applications and other devices. To meet security issues, users in it are recognized by using face recognition technology and AES between all data communications in it is applied. The proposed device’s usefulness is approved by implementing it in smart home environments.

콩에서 발생하는 강낭콩일반모자이크바이러스(BCMV)와 땅콩위축바이러스(PSV)의 저항성 평가

이영훈, 윤영남, 강범규, 김현영, 최만수, 구성철, 김현태, 윤홍태, 이수헌, 백인열 忠北大學校 農業科學硏究所 2014 農業科學硏究 Vol.30 No.2

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.

디지털 매체 혹은 가상현실에서 이미지의 문제

김성민,박영욱 한국철학사상연구회 2004 시대와 철학 Vol.15 No.1

디지털 기술 혹은 매체는 단순힌 새로운 기술의 출현만을 의미하는 것이 아니다. 그것은 인간의 지각과 상호 의사소통에서 새로운 변화를 의미한다. 이러한 근본적 변화의 성격 때문에 디지털 매체에 대한 철학적 고찰이 필요한 것이다. 이 논문은 디지털 이미지와 가상현실의 문제에 초점을 맞추어 디지털 매체가 어떤 인식론상의 근본적인 변화를 가지고 왔는지에 대해 철학적으로 논구할 것이다. 이에 대한 철학적 논의는 크게 세 가지 쟁점으로 압축될 수 있다. 먼저, 디지털 매체가 낳은 가상현실의 문제이다. 가상현실은 한편으로는 가상적이기도 하지만 또 한편으로는 현실적이기도 하다는 역설적 표현을 담고 있다. 따라서 가상현실의 이러한 역설이 어떻게 해명되어야 하며 그러한 역설이 실제로 디지털 매체 속에서 어떤 방식으로 진행되며, 인간의 지각방식이나 의사소통 체계에 어떤 영향을 끼치는지에 대한 논의가 진행된다. 둘째, 디지털 이미지의 비물질성이라는 특성에 관한 것이다. 주로이미지를 통해서 주어지는 디지털 매체의 정보형태는 '지금'과 '여기'라는 시공간적 규정을 벗어나있다는 특징을 지닌다. 이를 흔히 디지털이미지의 비물질성이라는 특성으로 요약할 수 있다. 이러한 디지털 이미지의 특성은 코드화되는 순간 이미 변형을 전제하므로 그것에 의해서 전달되는 의사소통의 체계 또한 일방적인 것이 아니다. 셋째, 디지털 이미지에 의한 가상현실이 지금까지 현실에 구속된 지각의 세계를 벗어나 새로운 세계를 창출하는가에 대한 물음이다. 여기서는 레비와 비릴리오의 전망을 대비시킴으로써 그 쟁점을 간단하게 살펴보는 것에 논의를 제약한다. The advent of digital technology or media does not simply mean the emergence of a new technology. Quoting Mcluhan, the appearance of a new medium means the alterations in the way of human perceptions and mutual communications. These kinds of the radical changes give a space for the philosophical penetration into the new technology. In this paper I'm just trying to give a rough but philosophical consideration on some issues about digital images, nonetheless eventually leaving the problems unsolved rather than settle down the issues. Considering the current situation of the new media in its initial stage, we can find a good excuse for the delay of a clear conclusion about these problems. Deleuze's saying "philosophy is not solving a problem but posing a problem" can have no more suitable place than in this case. The philosophical problems which are caused by the digital technology are summarized as following three. The first problem is related with the nature of the 'Virtual Reality'. Considered in its literal meaning, the word 'Virtual Reality' itself is contradictory. For the two terms 'virtual' and 'reality' which are all parts of the word are basically irreconcilable with each other. From this contradiction does the question follow inevitably. "Is a Virtual Real world a fictional world or another real world?" Secondly, It's the problem related with the 'immateriality of the digital image'. The fact that the digital image is beyond 'now' and 'here' can be summarized as it's 'immateriality'. This means that digital images (which are the main forms of information used by the digital media) have an unlimited possibility to be transformed. It can open a new horizon for a new type of human perception. Thirdly, is the new dimension produced by the digital media a so-called new world that leads us to the new world of perception unlike our everyday perception? This article deals with the two rival thinkers about this problem, Pierre Levy and Paul Virilio.

분산 어플리케이션의 정보보호 서비스를 위한 CAPI 설계 모델

이상기,김영덕,최용락 대전대학교 산업기술연구소 1998 산업기술연구소 論文集 Vol.9 No.2

Until recently, the integration of cryptographic functionality into application program has required that developers tightly couple the application to the cryptographic module. This approach forces each new combination of application and cryptography to be treated as a distinct development effort, and does not provide the modularity and maintainability. An approach that can provide flexibility and cost saving is the use of a standardized CAPI(Cryptographic Application Prigram Interface) suite. This Paper analyze the CAPI for the development of various types of security application programs in distributed environment. The analysis of CAPI are considered with the respect of 7 criteria items such as algorithm independence, application independence, cryptomodule independence, the degree of cryptographic awareness, modular design and auxiliary services, safe programming and security perimeter. In this paper, we suggested the basis of utilization to be selected for develope the cryptographic modules in distributed applications.

李相玩,朴永和,南賢祐,尹延根 동아대학교 공과대학 부설 한국자원개발연구소 1992 硏究報告 Vol.16 No.1

When using any of the aggregate production planning techniques mentioned in previous studies, it is generally assumed that the inputs of information are deterministic and easy to generate. However, the problem is more complex if the criteria and informations are expressed imprecisions. Therefore, it requires suitable method to deal with imprecisions. For select proper comparison method of fuzzy numbers in aggregate production planning with imprecise informations or criteria, this study use Dubois & Prade fuzzy number comparison method and Li-Lee fuzzy number comparison method among comparison methods fuzzy numbers. And then, proper method between two methods is selected. Also it is presented illustration.

A Geiger-M□ller(GM) radiation sensor is fabricated by using the vacuum system and gas feeding system. The base pressure of the vacuum system is 1X10^(-7)torr, and two MFCs(0~10sccm, ±1% accuracy of the full scale) are used to control the composition of filling gas exactly. The fabricated GM radiation sensor is simultaneously filled with the mixture of neon and clorine. The mica window(7.43mg/cm^(2)) is attached to the GM radiation sensor. The optimized GM radiation sensor has about 660V starting voltage, 125V plateua length, and 10%/100V plateau slope.

TiO₂박막을 이용한 광촉매반응의 응용

김영관,김성호,김동현 江原大學校 産業技術硏究所 1997 産業技術硏究 Vol.17 No.-

Photocatalytic reaction using TiO₂thin film was applied for the inactivation of coliform bacteria and the degradation of formic acid. UV processes coupled with and without TiO₂were tested for the river water samples. It took 5 and 15 minutes, respectively, to obtain 99% destruction of coliform bacteria in the total coliform test, which demonstrated the effectiveness of the photocatalytic reaction. Complete degradation of formic acid determined by TOC analysis was observed in 20 minutes by ozone/photocatalysis, while formic acid was degraded as little as about 20% during the first 100 minutes by ozone treatment alone. When ozone was supplied to the TiO₂/UV system, however, it provided a synnergetic effect for the degradation of formic acid.

The changing mordern society needs Various activities of leisure. Because Industrial Revolution gives us many chance of leisure time. This study was participation of "Spots for all" and research for citizen's leisure life in Sam Chok, are invertigeted from the 289 reguested questionare papers. As the results of this study, following results are attainable. 1. The recognition of "Sports for all" needs the citizens. Because over the half reguests does not know he fine definition of "Sports for all". 2. They prefer individual games to team games, for example, basket ball, soccer, volley ball etc. 3. Their provlem point of participation in "Sports for all" is too long to go to the public sport center. So, for the solution of this problem is capable of use the public school facilities. 4. The firest two purpose of participation in "Sports for all" investigated for thrir health and physical fitness. It represented fresh mind and generousity throught the "Sports for all" is the their first impotant point. 5. The value of leisure evaluated thesame as work. It represented the changing recognition of leisure by peoples. 6. The companion of participation in "Sports for all" represented first, friends, second, families. Theimportent point is they have not same time for each other in a family. 7. Too short of time is the first reason, their incapable of participation in "Sports for all". 8. Most of all their thought on the cost of leisure time for a month are about 50~190 thousand won.
