With the development of the IT industry and the increase of cultural activities, the demand for works increases, and they can be used easily and conveniently in an online environment. Accordingly, copyright infringement is seriously occurring due to the ease of copying and distribution of works. Some special types of Online Service Providers (OSP) use filtering-based technology to protect copyrights, but they can easily bypass them, and there are limits to blocking all illegal works, making it increasingly difficult to protect copyrights. Recently, most of the distributors of illegal works are a certain minority, and profits are obtained by distributing illegal works through many OSP and majority ID. In this paper, we propose a profiling technique for heavy uploader, which is a major analysis target based on illegal works. Creates a feature containing information on overall illegal works and identifies major heavy uploader. Among these, clustering technology is used to identify heavy uploader that are presumed to be the same person. In addition, heavy uploaders with high priority can be analyzed through illegal work Distributor tracking and behavior analysis. In the future, it is expected that copyright damage will be minimized by identifying and blocking heavy uploader that distribute a large amount of illegal works.

Velvet antlers from Cervus elaphus species are one of most famous, expensive and commonly used medicinal materials in traditional oriental medicine. Some distributor had illegal practice of disguising the origin of antlers in Korea market. Therefore, a test to distinguish antler essential to ensure the healthy development of the herbal industry. In this study, the variation in DNA sequences of the mitochondrial ATPase8 and cytochrome-coxidaseI (COI) genes of Cervus elaphus from China, the Republic of Altai, and Canada were evaluated. In addition, the sequence variation among, Rein deer and Cervus elaphus species was also evaluated. Although the sequences of deer from the Republic of Altai and Canada were very similar, polymorphisms that were conserved in each species were observed in the ATPase8 and COI genes. Therefore, these polymorphic markers could be used to distinguish Cervus elaphus antlers from different locations.

Many studies have been investigated on high density plasma source (Electron Cyclotron Resonance, Inductively Coupled Plasma, Helicon plasma) for large area source after It is announced that productivity of plasma process depends on plasma density. In this presentation, we will propose the new concept of the multiple source, which consists of a parallel connection of ICP sources and helicon plasma sources. For plasma uniformity, equivalent power (especially, equivalent current in ICP & Helicon) should distribute on each source. We design power feeding line as coaxial transmission line with same length of ground line in each source for equivalent power distribution. And we confirm the equivalent power distribution with simulation and experimental result. Based on basic study, we develop the plasma source for oxidation in semiconductor process. we will discuss the relationship between the processing parameters (With or WithOut magnet, operating pressure, input power ). In ICP, plasma density uniformity is uniform. In ICP with magnet (or Helicon) plasma density is not uniform. As a result, new design (magnet arrangement and gas distributor and etc..) are needed for uniform plasma density in ICP with magnet and Helicon.

This paper tries to solve the problems which previous methods have such as the WCDRM(Watermark and Cryptography DRM) and the model using smart card for protecting digital contents. This study provides a contents distribution model to protect the rights of author, distributor, and user as well as user's information by using technologies such as cryptography, DRM(Digital Right Management), access control, etc. The proposed system is evaluated as the most safety model compared with previous methods because it not only solves the problems which the previous methods have, but also protects four type of risks such as use of contents which other mobile devices download, the attack on the key to decode the message, the attack on leaking the contents, and the internal attack such as an illegal reproduction.

Mobile (smartphone) search engine marketing is increasingly important. Accordingly, the development of visual apparel search technology to obtain easier and faster access to visual information in the apparel field is urgently needed. This study helps establish a proper classifying system for an apparel search after an analysis of search techniques for apparel search applications and existing domestic and overseas apparel sites. An annotation technique is developed in accordance with visual attributes and apparel categories based on collected data obtained by web crawling and apparel images collecting. The categorical composition of apparel is divided into wearing, image and style. The web evaluation site traces the correlations of the apparel category and apparel factors as dependent upon visual attributes. An appraisal team of 10 individuals evaluated 2860 pieces of merchandise images. Data analysis consisted of correlations between apparel, sleeve length and apparel category (based on an average analysis), and correlation between fastener and apparel category (based on an average analysis). The study results can be considered as an epoch-making mobile apparel search system that can contribute to enhancing consumer convenience since it enables an effective search of type, price, distributor, and apparel image by a mobile photographing of the wearing state.

비료 살포는 작물 생장 촉진을 위하여 반드시 필요한 작업이며 재배 관리의 반 이상을 차지하는 중요한 농작업이다. 비료 사용은 양분 공급과 토양의 물리 화학성 개선 등 여러 이점이 있으나 최근에는 과도한 비료 사용으로 양분의 불균형 등의 문제점이 대두되고 있다. 또한 수작업으로 비료를 살포할 시 유해한 성분이 피부에 흡수되고 작업 능률이 낮기 때문에 비료 살포기의 필요성을 가진다. 현재 시중에 판매되고 있는 비료 살포기는 고속의 기류를 이용하여 비료를 날리는 방법과 중력으로 낙하시키는 방법, 원심력을 가하여 멀리 날려 보내는 방법 등이 있다. 그 중 중력으로 낙하시키는 방법과 고속 기류를 사용하는 방법은 석회, 퇴비, 규산질 비료 살포에 부적절함으로 원심력을 이용한 비료 살포가 많이 사용된다. 하지만 원심력을 이용하여 날리는 방법은 구조가 단순하여 비료가 균일하게 확산되지 않고 트랙터의 이동 속도에 따라서 비료의 살포량이 달라진다. 그에 따라 과도한 비료 살포로 이어지며 토지 또한 양분의 불균형 등으로 환경의 문제점이 대두되고 있다. 국내에서는 균일 살포를 위하여 비료 살포기의 내부 날개의 각도를 조절하여 비료 살포의 패턴을 분석하는 연구가 진행되고 있다. 균일 살포의 중요성은 더욱 대두되고 있지만 현재 균일 살포에 대한 연구가 많이 부족한 상태이다. 본 연구에서는 기존의 비료 살포기에 균일 살포를 위한 설계 인자를 도출하기 위해 살포기를 분석하여 원심식 비료 살포기의 균일 살포를 위한 기초 자료로 활용하고자 한다.

During the operation of Circulating Fluidized Bed Combustion Boiler, defluidization is mainly caused by the formation of clinker. The clinker is made of components of Si, Fe, Ca, etc. However, although the defluidization is widely researched, the major factor has not been validated yet clearly. In this study, in the view of the shape and the arrangement of nozzles at a distributor (type 1, type 2), the formation of clinker is examined by CFD calculations and an improved nozzle design is proposed.

In the previous study, it is proved by numerical simulation that the baffle shaped as the porous plate installed in the inlet chambers improves the redistribution of the flow injecting to the tube bundles. In the present study, numerical simulation has been performed to investigate the effects of the flow distributors on the thermal characteristics of the shell and tube heat exchangers. The flow fields have been analysed by the three-dimensional Navier-Stokes solvers including the thermal conditions on the shell sides. The numerical results showed that the presence of the baffles improves the redistribution of the heat transfer to the tube bundles though the overall performance drop slightly on the present flow conditions.

Partner relationship management (PRM) refers to processes and methodologies associated with managing the relationship between corporations and their partners. Recently, the importance of PRM has been increasingly emphasized, and it is considered as a core competitive factor for firms whose sales heavily rely on the intermediate distributor. In this paper, we identify key success factors for PRM system based on literature review on CRM system and interviews with domain experts, and prioritize them from two different perspectives, firms and partners, based on analytical hierarchy process. Partners responded that trust-building between firms and partners, quality of system, and satisfaction level for information system have high priorities, while firms responded that quality of system, information share, and trust building between firms and partners. Identified factors and evaluated priorities can provide a strategic guideline when planning the PRM system building.
