  • 현재 대부분의 가정이나 소규모 기업에서는 인터넷 서비스를 이용하기 위하여 ADSL(Asymmetric Digital Subscriber Line)나 케이블모뎀을 사용한다. 4바이트로 구성되는 현재의 인터넷 IP 주소체계(IPv4)에서는 할당 가능한 IP 주소가 부족하여, 동적으로 공인(Public) IP 주소를 할당하는 방식을 사용하고 있다. 이러한 동적인 IP 주소를 할당받는 시스템은 모든 인터넷 서비스를 이용하는 데에는 아무런 제약이 없지만, 자신이 각종 인터넷 서버 기능을 수행하는 데는 많은 문제점이 있다. 본 논문에서는 동적으로 변하는 IP 주소를 가진 시스템에서 인터넷 서버 서비스(Telnet, FTP, HTTP, Mail 등)가 가능하도록 하는 게이트웨이(Gate-D)를 설계하였으며, 실험적으로 Gate-D를 이용한 Telnet 서버의 구축을 통하여 유용성을 확인하였다.

  • 최근 많은 프로세서 제작업체들이 프로세서의 효율을 높이기 위한 방법으로 독립적인 쓰레드들을 한 프로세서 사이클에 동시에 실행시킬 수 있는 동시다중 쓰레딩 기술을 구현하고 있으며 그 예의 하나가 하이퍼쓰레딩이다. 물리 프로세서 안에 여러 개의 논리 프로세서를 가질 수있는 하이퍼쓰레딩 기술은 기존의 여러 개의 독립적인 프로세서들을 갖춘 멀티 프로세싱 환경과는 차이가 있으며, 하이퍼쓰레딩 환경에 알맞은 특정한 작업 할당 방법이 필요하다. 따라서, 본 논문에서는 하이퍼쓰레딩 기술에 적합한 스케줄링 알고리즘을 제안하고 그 성능을 다양한 방법으로 측정해 봄으로서 하이퍼쓰레딩 시스템을 올바르게 인식하고 적절하게 관리하여 효율적인 성능을 기대할 수 있게 되었다.

  • The purpose of this paper is to review critically the validity and relevance of the pan-national language culture improvement movement, Annyeong! Urimal(Hello! Our Language) implemented for the last three years as part of the government-driven projects, and to seek for improvement direction or fundamental reorientation of this movement. In order to accomplish this purpose, this paper firstly points out abstract and conventional aspects of the diagnosis for background and the purpose of projects, and suggests that this movement focuses on verbal abuse rather than language destruction and pays attention to positive aspects of newly rising language use. Then, with reference to main agent, this paper argues that the government must lead actively formation of voluntary nongovernmental agent with indirect financial and institutional support. Thirdly, it is suggested that public language should be the top priority target sphere and the language used by the leaders of society and the older generation should be also included in the target spheres of this movement. Finally, this paper indicates that enlightenment/public relation projects end often in one time events, imposing unilaterally the normative contents, and also emphasizes the importance of survey/research projects and deliberation/evaluation projects.

  • A checkrein deformity can occur after a distal tibiofibular fracture. Usually, a checkrein deformity due to a dysfunction of the extensor hallucis longus muscle is rarer than that of the flexor hallucis longus. Only a few related studies have been reported. The authors encountered an extensor hallucis longus checkrein deformity due to extensor retinaculum syndrome while managing a triplane fracture. In magnetic resonance imaging, an increase in the heterogeneous signal was observed on the T2-weighted images suggesting muscle necrosis or ischemic changes in a part of the extensor hallucis muscle. Postoperative great toe motor weakness, unintentional movement, sensory changes, and weakness improved spontaneously during the follow-up.

  • In this paper, we propose a novel visualization technique to explain the predictions of deep neural networks. We use knowledge distillation (KD) to identify the interior of a black-box model for which we know only inputs and outputs. The information of the black box model will be transferred to a white box model that we aim to create through the KD. The white box model will learn the representation of the black-box model. Second, the white-box model generates attention maps for each of its layers using Grad-CAM. Then we combine the attention maps of different layers using the pixel-wise summation to generate a final saliency map that contains information from all layers of the model. The experiments show that the proposed technique found important layers and explained which part of the input is important. Saliency maps generated by the proposed technique performed better than those of Grad-CAM in deletion game.

  • Water distribution networks (WDNs) are designed to satisfy water requirement of an urban community. One of the central issues in human history is providing sufficient quality and quantity of water through WDNs. A WDN consists of a great number of pipelines with different ages, lengths, materials, and sizes in varying degrees of deterioration. The available annual budget for rehabilitation of these infrastructures only covers part of the network; thus it is important to manage the limited budget in the most cost-effective manner. In this study, a novel pipe replacement scheduling approach is proposed in order to smooth the annual investment time series based on a life cycle cost assessment. The proposed approach is applied to a real WDN currently operating in South Korea. The proposed scheduling plan considers both the annual budget limitation and the optimum investment on pipes' useful life. A non-dominated sorting genetic algorithm is used to solve a multi-objective optimization problem. Three decision-making objectives, including the minimum imposed LCC of the network, the minimum standard deviation of annual cost, and the minimum average age of the network, are considered to find optimal pipe replacement planning over long-term time period. The results indicate that the proposed scheduling structure provides efficient and cost-effective rehabilitation management of water network with consistent annual budget.

  • Pulse diagnosis that distinguishes internal injury from external injury by comparing the left and right of the chon pulse was formed in the process of Naegyoung's pulsation theory of ST9 and LU9 being assimilated into diagnostic method by taking chon pulse. The founder of school of internal injury, I Dong-won, expanded the horizon for this method to be widely used in clinical practice by especially explaining the specific application and theoretical background. According to him, pulse at ST9 which means chon pulse at the left hand, is bigger than the chon pulse at the right hand, it reflects external injury. Bigger "entrance pulse", a chon pulse at the right hand means internal injury. The reason is the left side of the body is a path for Yanggi so it controls the exterior part and the right side of the body is a path for Eumgi to descend so it controls the interior part. Internal injury develops as the spleen and stomach get injured. If the spleen and stomach is damaged essence derived from food cannot ascend to the stomach and will flow back to the lower part. As a result, fire of Eum type formed at the lower part will shoot up to the upper part and manifests external injury-like exterior syndromes. In this case, evidence distinguishing between internal and external injury is the fact that right hand pulse is bigger than the left hand. The important reason for distinguishing between internal and external injury is because when treating external injury caused by excess syndrome, pathogenic Gi should be dispelled. However, treating internal injury cased by deficiency syndrome, requires promoting the primordial Gi.
