공공의 이익이라는 목적을 가지고 공공기관에 의해 만들어지거나 공공기금을 통해 만들어진 공공성과물은 공공의 자산임과 동시에 학문과 산업 발전이라는 가치에 따라 상업적 활용까지도 가능하다. 그런데 이러한 공공성과물을 상업적으로 이용하는 과정에서 발생하는 부작용으로서 일부 민간 출판사가 공공성과물을 그대로 출판하여 고가에 판매하는 문제가 발생하고 있다. 그리고 이러한 출판물에 대해서는 납본에 따른 보상금이 지급되고 있으며, 공공도서관을 대상으로 판매이득을 취하는 것 역시 문제라고 볼 수 있다. 그뿐만 아니라 출판물에 대한 오인으로 인해 발생하는 민원, 전자책 시장의 확대에 따른 상업적 출판의 용이성, 공공대출권 도입 가능성에 따른 보상금 문제 발생 등에 대한 우려도 있다. 공공성과물은 민간 영역에서의 2차적 활용을 통해 새로운 부가가치를 창출하고 핵심 자원으로서 높은 시장성을 가질 수 있다는 점에서는 상업적 이용이 보장되어야 하지만, 과연 어떠한 개선의 노력도 없이 이루어지는 공공성과물의 출판이 이러한 기대에 부응하고 있는가에 대해서는 생각해 볼 필요가 있다. 따라서 본 연구에서는 바람직한 출판문화의 정착과 출판 산업의 성장을 위해 공공성과물을 상업적으로 출판하는 과정에서 발생하는 문제점과 그 외에 검토가 요구되는 문제들에 대해 살펴보고, 개선방안으로서 출판문화산업진흥법 및 저작권법, 도서관법, 국회도서관법의 개정안과 함께 관련 기관에 의한 제재·협조 방안을 제시하고자 한다. Public product, which is created by public institutions with the purpose of the public interests or created with public funds, is a public asset and can be used for commercial utilization depending on the value of academic and industrial development. However, as a side effect, some publishers publish them as they are and sell them at high prices. In addition, compensation for specimen copy is paid in spite of identical publications and such publications derive benefits from public libraries. Furthermore, there are concerns about misconception on the publications, ease of commercial publication in e-book market, and possibility of compensation for Public lending right. In the sense that public product creates new added values through secondary utilization in private sectors and has high marketability, commercial utilization needs to be guaranteed. Nevertheless, it is necessary to consider whether commercial publication without any improvement, meets these expectations. Thus, this study looks into the problems that occur in the process of commercial publication of public product and other issues that need to be reviewed, proposing improvement plans including the revision of Publishing Industry Promotion Act, Copyright Act, Libraries Act, and National Assembly Library Act.
Adaptive QoS Mechanism for Wireless Mobile Network
KwangSik Kim,Shintaro Uno,MooWan Kim 한국정보과학회 2010 Journal of Computing Science and Engineering Vol.4 No.2
Wireless mobile multimedia communications have been greatly increased in the number of users, diversity of applications and interface technologies. Wireless mobile networks are being evolved and integrated into IP based core network, so it is necessary to provide sufficient QoS (Quality of Service) mechanism to provide enhanced user’s satisfaction. In this paper, we propose a new adaptive QoS mechanism based on utility function borrowed from the field of microeconomics, call setup and handover signaling mechanism integrating QoS and mobility management. Through a simulation, we show that adaptive resource allocation based on user preferences can be realized in the wireless mobile network with some considerations.
Loss Recovery Scheme for TCP Using MAC MIB over Wireless Access Networks
KwangSik Shin,Jinhyuk Kim,Sang Bang Choi IEEE 2011 IEEE communications letters Vol.15 No.10
<P>In the wireless network, if the TCP cannot identify the wireless error, it overly reduces the transmission rate by unnecessarily cutting the congestion window down. Therefore, to improve TCP goodput by accurately detecting wireless loss, we propose the MAC MIB based loss recovery scheme that can differentiate between congestion loss and wireless loss without intervention of any intermediate node. The simulation results show that the goodput is substantially enhanced compared to existing schemes in the wireless access network environment, where errors tend to occur in burst due to the intrinsic wireless link characteristics.</P>
Successful Surgical Treatment of Severe Lower Lip Avulsion in Two Cats
Kwangsik Jang,Yangwon Chae,Euisin Yang,조현민,Kyung Mi Shim,Chun-Sik Bae,강성수,김세은 한국임상수의학회 2022 한국임상수의학회지 Vol.39 No.5
Two Korean short-haired cats were admitted to the Veterinary Med- ical Teaching Hospital, Chonnam National University, with severe lower lip avulsion. In the first case, the treatment was performed using the tension-free suture technique with rubber tube stents. The second case was treated using the tension-free suture technique with rubber tube stents for lip avulsion and using the cerclage wiring technique for alveolar fracture. The teeth around the alveolar fracture were extracted and bone graft and collagen membrane were applied at the alveolar fracture site to stabilize the mandibular alveolar fracture. Thereafter, the cerclage wire was placed circumferentially around the mandible. In both cases, normal function of the oral cavity was successfully recovered by repairing the anatomic abnormality. In conclusion, tension-free suture technique can be a treatment option for bilateral lower lip avulsion in cats.
