It is not an exaggeration to say that our society is already one of disputes. Since circa 2010, the average number of lawsuits filed every year is upwards of six million cases, and resolving disputes through trials is already fully saturated. The functional roles of the court reflect that there are many lacking areas such as systems, tools, and procedures related to social integration. In addition, ADR, which is carried out in advanced capitalist nations to supplement the judicial functions, has also been implemented in our society for the past 60 years. However, for the reason why the usage rate of ADR did not increase for legal consumers, we cannot overlook government activities that did not make sufficient promotions related to the lack of awareness. In Korea, ADR is mainly composed of government-initiated types, and in particular, there is no ADR framework act that can play an integrated role. Furthermore, for the conciliation system of the court, over 80%of conciliation are conducted focusing on court of lawsuits, and legal basis and procedures between institutes are different for administrative ADR, and communication does not go smoothly, thus making it inefficient. Such examples cannot avoid being a background for criticism when considering the fundamental ideologies and beliefs of ADR. The Vinaya Pitaka of sangha related to ADR is a separate method for operating communities. This is the BDR (Buddhist Dispute Resolution) method that encompasses personal ethics, organizational ethics, harmony through various community gatherings, and adhikaranasamatha on the four issues that could occur in legal review procedures. This has become the sufficient background for succession and development for parisa sangha and gana sangha among individuals.

Video Content owners seek to squeeze the maximum amount of revenue from their assets via distribution into more territories. Digital Cinema Package(DCP), trusted solution to distribute protected content to theaters, caters to relatively small user base, which limits revenue. With the growth of the Internet & other digital media, the economics of media content has changed dramatically. Security remains main concern to deliver content to millions of consumers using intelligent digital display devices like Tablets, Smartphones, Smart TVs, Desktop & Laptop. By making the video content available to this segment securely, content owners will benefit from increased revenue. Through this paper we propose Open Source HomeDCP model to distribute the content to home users for offline viewing. We propose to include other open source CODEC than JPEG2000/MPEG2, which are specifically designed for theatrical performance. Final image size will be further reduced considering the display device resolution where video will be finally played. Key Delivery Message(KDM) system to be altered to suit new devices. This will be a big boost to Content Economy as content owners would be able to distribute the content securely to the wider audience & ensure more revenue.

본 논문에서는 무선 센서 네트워크에서 센싱 정밀도에 기반 한 그룹화 통신 프로토콜 (SRG)을 제안한다. SRG 는 센서 노드가 밀집해 있는 네트워크에서 응용계층이 요구하는 센싱 정밀도를 만족시키는 방법을 제공하는데, 그룹 헤더 노드를 매 round 마다 라운드-로빈 방식으로 교체하여 전반적인 센싱 정밀도를 높이고 각 노드가 소모하는 에너지를 비슷하게 되도록 만든다. 또한 라우팅 시에 소모되는 에너지를 줄이기 위해 그룹의 크기와 에너지 소모를 고려한 중계 노드를 선택 방법 제안하여 에너지 효율적인 통신이 이뤄지도록 한다. 성능평가를 위한 모의실험 결과 제안한 SRG 프로토콜은 센서노드들의 에너지 소비량을 줄이고 네트워크의 생존시간을 늘리는 것을 알 수 있다.

In SRM drive, the ON OFF angles of each phase switch should be accurately controlled in order to control the torque and speed stably. The accuracy of the switching angles is dependent upon the resolution of the encoder and the sampling period of the microprocessor, that are used to provide the information of the rotor position and to control the SRM power circuit, respectively. However, as the speed increases, the amount of the switching angle deviation from the preset values is also increased. Therefore, the low cost encoder suitable for the practical and stable SRM drive is proposed and the control algorithm to provide the switching signals using the simple digital logic circuit is also presented in this paper. As a result, a stable high speed SRM drive can be achieved by the high resolution switching angle control and it is verified from the experiments that the proposed encoder and logic controller can be a powerful candidate for the practical low cost SRM drive.

This paper deals with the development of RACOM(Radar Signal Detecting ＆ Processing Computer). RACOM is a radar display system specially designed for radar scan conversion, signal processing and PCI radar image display. RACOM contains two components； i )RSP(Radar Signal Processor) board which is a PCI based board for receiving video, trigger, heading & bearing signals from radar scanner ＆ tranceiver units and processing these signals to generate high resolution radar image, and ⅱ）Applications which perform ordinary radar display functions such as EBL, VRM and so on. Since RACOM is designed to meet a wide variety of specifications(type of output signal from tranceiver unit), to record radar images and to distribute those images in real time to everywhere in a networked environment, it can be applicable to AIS(Automatic Identification System) and VDR(Voyage Data Recorder).

Eosinophils are terminally differentiated cytotoxic effector cells that have a role in parasitic infections and allergy by releasing their granule-derived cytotoxic proteins. However, an increasing number of recent observations indicate that eosinophils are not only associated with the pathogenesis of a wide range of diseases, but also contribute to the maintenance of homeostatic responses in previously underappreciated diverse tissues, such as the gastrointestinal (GI) tract and adipose tissue. In this review, we describe biological characteristics of eosinophils, as their developmental properties, permissive proliferation and survival, degranulation activity, and migration properties enable them to distribute to both homeostatic and inflamed tissues. We describe pathologic aspects of eosinophils with a role in asthma and in various GI diseases, including eosinophilic GI disorders, inflammatory bowel disease, and radiation-induced enteropathy. Finally, we discuss the beneficial role of eosinophils, which contribute to the resolution of pathogenic conditions and to the modulation of homeostatic biologic responses.

연속된 초음파 영상 시퀀스로부터 파노라마 영상을 만들기 위해서는 인접된 프레임 사이의 움직임을 추정해야 한다. 기존에는 고정 블록 움직임 추정 방법이 주로 사용되고 있는데 본 논문은 정확성을 높이고 계산시간을 단축하기 위해 다해상도 영상을 이용한 특징점 기반 블록 움직임 추정 방법을 제안한다. 기존의 블록 움직임 추정 방법은 규칙적으로 블록을 배치하기 때문에 추정된 움직임의 정확도를 높이기 위해서는 블록의 크기가 커지기 때문에 처리 시간이 오래 걸린다. 본 논문에서는 특징점을 중심으로 블록을 배치하여 움직임 추정의 정확도는 유지하면서 블록의 크기를 줄일 수 있었다. 어파츄어문제(aperture problem)을 줄이기 위해 코너점을 특징점으로 하였다. 움직임 추정 영역은 일정한 크기의 부영역으로 나누고, 각 부영역에서 가장 코너 강도가 큰 점을 선택하였다. 특징점을 선택하는 데는 해리스 스테판 코너검출기를 사용하였다. 코너점들이 한 곳으로 편중될 경우 블록들이 움직임 추정 영역에서 골고루 분산되지 않아 이렇게 구한 블록 움직임을 이용하여 전역 움직임을 구하면 오차가 커진다. 본 논문에서는 이러한 문제를 해결하기 위해 특징점을 선택하는 영역에 제한을 두도록 하였다. 초음파 영상에는 스펙클과 잡음이 많아 코너점을 구하기 전에 영상 평활화를 해야 한다. 계산시간을 줄이고 잡음이 감소된 영상에서 코너점을 구하기 위해 저해상도 영상에서 블록 움직임을 구한 후 점점 고해상도로 확산하는 형태로 다해상도 영상을 사용한다. 실제 세가지 종류의 초음파 영상 시퀀스에 대해 실험결과 제안된 방법은 기존의 방법에 비해 움직임 추정 오차(Displaced Frame Difference)를 평균 66.02에서 58.98로 줄이면서 계산시간은 평균 71ms에서 44ms 으로 빠르게 됨을 알 수 있었다.

Simulation of flow past a complex marine structure requires a fine resolution in the vicinity of the structure, whereas a coarse resolution is enough far away from it. Therefore, a lot of grid cells may be wasted, when a simple Cartesian grid system is used for an Immersed Boundary Method (IBM). To alleviate this problems while maintaining the Cartesian frame work, we adopted an Adaptive Mesh Refinement (AMR) scheme where the grid system dynamically and locally refines as needed. In this study, We implemented a moving IBM and an AMR technique in our basic 3D incompressible Navier-Stokes solver. A Volume Of Fluid (VOF) method was used to effectively treat the free surface, and a recently developed Lagrangian Dynamic Subgrid-scale Model (LDSM) was incorporated in the code for accurate turbulence modeling. To capture vortex induced vibration accurately, the equation for the structure movement and the governing equations for fluid flow were solved at the same time implicitly. Also, We have developed an interface by using AutoLISP, which can properly distribute marker particles for IBM, compute the geometrical information of the object, and transfer it to the solver for the main simulation. To verify our numerical methodology, our results were compared with other authors' numerical and experimental results for the benchmark problems, revealing excellent agreement. Using the verified code, we investigated the following cases. (1) simulating flow around a floating sphere. (2) simulating flow past a marine structure.
