A modification of a colorimetric assay was used to determine the concentration of total and individual sulfated-glycosaminoglycan (GAG) in equine synovial fluid and serum with joint disease. For the identification of enzymatic active products of the equine synovial fluid, strong anion exchange-high performance liquid chromatography (SAX-HPLC) was performed. By the action of chondroitin ABC lyase, three unsaturated disaccharides, 2-acetamide-2-deoxy-3-O-(β-D-gluco-4-enepyranosyluronic acid)-D-galactose (△Di-COS), 2-acetamide-2- deoxy-3-O-(β-D-gluco-4-enepyranosyluronic acid)-6-O-sulfo-D-galactose (△Di-C6S), and 2-acetamide-2-deoxy-3-O-(β-D-gluco-4-enepyranosyluronic acid)-4-O-sulfo-D-galactose (△Di-C4S), were produced from the equine synovial fluid. Total GAG concentration of the equine synovial fluid was 0.82± 0.24 ㎎/㎖ (mean±SD) in normal horses, but it was decreased in horses with joint disease (0.17±0.12 ㎎/㎖). The concentration of keratan sulfate (KS), chondroitin sulfate (CS), and hyaluronic acid (HA) were decreased in horses with joint disease. The concentration of serum HA of normal horses was 77.00±66.14 ㎍/㎖, but it was markedly increased in joint diseases (168.50±147.50 ㎍/㎖), There appears to be some correlation between joint inflammation and serum HA levels as determined by experimental studies of animals. Irrespective of the explanation, it is clear that measurement of the level of serum HA may provide a useful marker for monitoring the onset and progression of a number of important diseases and disorders in equine.

현재 국내는 4차산업이 활성화됨에 따라 디지털정보화 사회로 급속적인 발전을 이룩하였다. 이에 User들은 스마트 폰이나 태블릿 PC 등의 디바이스장치를 통해 새롭고 다양한 정보와 자료들을 획득 및 수집하고 있는 추세이다. 이렇게 다양한 콘텐츠와 서비스가 실시되고 있음에도 불구하고, User들의 요구는 점차적으로 극대화되고 있으며, 이를 충족하고자 TUI기반의 콘텐츠들이 우후죽순 생겨났으나 기존의 테이블 탑 디스플레이에 새로운 인터페이스인 스마트 퍽을 사용을 하는데 있어서 다수의 User가 동시에 접근을 하지 못하는 어려움이 있었다. 이에 대해 본 논문에서는 스마트 퍽 시스템에 User를 위한 보안인증 시스템을 구축하고 이를 통해 스마트 퍽에 대한 User를 구분하고 인증하는 시스템을 적용하였고, 다수의 User가 동시적으로 인터페이스에 접근 하였을 때, 발생되는 보안적인 문제점을 해결하였다. As the digital information society develops, services for providing mutual interfaces between various digital devices and users are being implemented. Therefore, users acquire and use a lot of information through various devices such as smart phone and tablet PC. It is a very common sight for a user to handle multiple devices in an interface. These user-oriented interfaces have gradually evolved from the existing methods and have developed new interfaces to the present. The TUI (Tangible User Interface) is a realistic interface technology that provides physical manipulation of digital information. It is an interactive interface that enables digital information to be applied to physical objects so that users can use them conveniently in daily life. In this study, we implemented a service that provides users with more various contents and additional elements by inter working with smart puck system using physical objects. User authentication using LEA (Lightweight - Encryption Algorithm) encryption algorithm, which has been researched and developed in Korea, so as not to cause a collision when accessing contents at the same time, The system was designed and constructed, user authentication was classified so that it could be applied to smart puck system after construction, and multiple users access the interface at the same time to solve the conflict problem.

RF 유도탄 탐색기 알고리즘을 활용한 기능성 게임 시뮬레이터 환경 모델 구현

배종환(Jong-Hwan Bae),김만규(Man-Gyu Kim),변재정(Jai-Jeong Pyun) 한국엔터테인먼트산업학회 2017 한국엔터테인먼트산업학회논문지 Vol.11 No.5

RF 유도탄 탐색기 알고리즘을 통한 기능성 게임 시뮬레이터 구현을 위해서는 실질적인 유도탄공격효과분석을 필요로 한다. 이를 위해서는 유도탄의 Seeker의 탐색 및 추적을 위한 표적의 RCS 및 IR 산출 모형이 매우 중요하다. 하지만 현재까지의 훈련체계는 표적을 생성할 때 표적 크기를 선택하여 모의가 진행되고 있어 유도탄 비행방향과 표적의 이동방향에 따른 상대적 표적 크기를 반영하기에는 미흡한 실정이다. 이에 본 논문에서는 비례항법 알고리즘에 의해 기능성 게임 시뮬레이터 상에서 효과적인 유도탄 공격 효과 모의가 가능하도록 탐색기 모의중 RF 유도탄에 대한 표적의 RCS 값을 3D 객체 모델을 적용하여 동적인 환경에 맞게 사실적으로 산출하도록 하였다. 각 방위별 반사율을 계산하기 위해 실 환경에서 측정된 RCS와 3D 객체 모델에서 산출된 CS의 상대적 가중치를 계산하였으며, 3D 객체의 동적인 변화가 RCS 측정에 반영되어 유도탄 탐색기가 표적을 탐지 및 추적을 모의하는데 유도탄과 표적의 상대적인 변화가 반영되도록 하였다. 실험으로는 5개의 표적을 배치하고 RF 유도탄은 RCS가 큰 표적으로 유도되도록 가정하여 예측 결과를 도출하여 전투훈련 또는 전투모의시 실시간 유도탄 탐색기의 탐지효과 및 공격 형태에 대한 신뢰성 있는 결과를 산출하였다. In order to implement the functional game simulator through RF Anti-Missile search algorithm, it is necessary to analyze effect of Anti-Missile attack. For this purpose, the RCS and IR calculation models of targets for searching and tracking the missile’s Seeker are very important. However, the training system does not sufficiently reflect the relative target size according to the missile direction and the direction of the target movement because the simulation is proceeding by selecting the target size when generating the target. In this paper, the RCS value of the target for RF missile in the explorer simulator is realistically calculated according to the dynamic environment by applying the 3D object model to simulate the missile attack on the functional game simulator by the proportional navigation algorithm. In order to calculate the reflectance for each bearing, we calculated the relative weights of the RCS calculated in the real environment and the 3D object model, and the dynamic change of the 3D object was reflected in the RCS measurement. The simulations were made to reflect the relative changes in the targets and targets. In the experiment, five targets were placed and the RF missile was assumed to be derived as a large target. Then, in the battle training or combat simulations, we calculated the reliable detection results and the attack type of real - time guided missile explorer.

Jong-Hwan Bae(배종환),Kyung-Sik Kim(김경식),Kyu-Hyuk Chung(정규혁) 한국멀티미디어학회 2010 한국멀티미디어학회 학술발표논문집 Vol.2010 No.1

Low-Density Parity-Check (LDPC) codes are error correcting codes with good performance in communications systems. LDPC codes, however, have heavy computational complexity. In this paper, we find out how many iterations are required for sufficient performance of LDPC codes. The Additive White Gaussian Noise (AWGN) channel model and a log-domain Sum-Product (SP) algorithm are used. Experiments measure Bit Error Rate (BER) at each iteration in given SNRs. The result of performance evaluation, the best performance is showed when the number of iteration is 25 at 5 ㏈.

인터랙티브 전시 환경에서 개인화 마케팅 서비스를 위한 모바일 프레임워크 설계

배종환(Jong-Hwan Bae),소수환 (Su-Hwan Sho),최이권(Lee-Kwon Choi) 한국지능정보시스템학회 2012 지능정보연구 Vol.18 No.1

기존의 전시환경에서 전시 참여업체는 처음에 작성된 개인 정보를 사용하여 모든 관람객에게 동일한 마케팅 정보를 전달하게 된다. 즉, 전시 관람객의 선호도나 반응의 변화에 따른 적절한 대비가 어렵고 개인 별 선호 취향에 따른 개별 대응이 힘들다. 관람객 개개인에게 차별화된 맞춤형 서비스를 제공하기 위해서는 관람객 개개인의 의도를 인지할 수 있어야 하고, 그 인지된 정보를 기준으로 해서 선별적인 서비스를 제공해야 한다. 본 논문에서는 전시 공간에서 관람객 개개인의 선호도와 상황을 인식하고, 인식된 정보를 기반으로 하여 관람객 개인별로 가장 적합한 전시 참가 업체의 마케팅 정보나 부스 정보를 관람객이 소유한 스마트 폰을 통해 제공 하며, 전시 공간에 설치되어 있는 인터랙션이 가능한 디바이스들과 전시 관람객 개개인이 소지하고 있는 스마트 폰 간의 인터랙션 서비스를 제공하기 위한 모바일 프레임 워크를 설계하였다. As exhibition industry, which is a part of 17 new growth engines of the government, is related to other industries such as tourism, transportation and financial industries. So it has a significant ripple effect on other industries. Exhibition is a knowledge-intensive, eco-friendly and high value-added Industry. Over 13,000 exhibitions are held every year around the world which contributes to getting foreign currency. Exhibition industry is closely related with culture and tourism and could be utilized as local and national development strategies and improve national brand image as well. Many countries try various efforts to invigorate exhibition industry by arranging related laws and support system. In Korea, more than 200 exhibitions are being held every year, but only 2~3 exhibitions are hosted with over 400 exhibitors and except these exhibitions most exhibitions have few foreign exhibitors. The main reason of weakness of domestic trade show is that there are no agencies managing exhibition-related statistics and there is no specific and reliable evaluation. This might cause impossibility of providing buyer or seller with reliable data, poor growth of exhibitions in terms of quality and thus service quality of trade shows cannot be improved. Hosting a lot of visitors (Public/Buyer/Exhibitor) is very crucial to the development of domestic exhibition industry. In order to attract many visitors, service quality of exhibition and visitor's satisfaction should be enhanced. For this purpose, a variety of real-time customized services through digital media and the services for creating new customers and retaining existing customers should be provided. In addition, by providing visitors with personalized information services they could manage their time and space efficiently avoiding the complexity of exhibition space. Exhibition industry can have competitiveness and industrial foundation through building up exhibition-related statistics, creating new information and enhancing research ability. Therefore, this paper deals with customized service with visitor's smart-phone at the exhibition space and designing mobile framework which enables exhibition devices to interact with other devices. Mobile server framework is composed of three different systems; multi-server interaction, server, client, display device. By making knowledge pool of exhibition environment, the accumulated data for each visitor can be provided as personalized service. In addition, based on the reaction of visitors each of all information is utilized as customized information and so the cyclic chain structure is designed. Multiple interaction server is designed to have functions of event handling, interaction process between exhibition device and visitor's smart-phone and data management. Client is an application processed by visitor's smart-phone and could be driven on a variety of platforms. Client functions as interface representing customized service for individual visitors and event input and output for simultaneous participation. Exhibition device consists of display system to show visitors contents and information, interaction input-output system to receive event from visitors and input toward action and finally the control system to connect above two systems. The proposed mobile framework in this paper provides individual visitors with customized and active services using their information profile and advanced Knowledge. In addition, user participation service is suggested as well by using interaction connection system between server, client, and exhibition devices. Suggested mobile framework is a technology which could be applied to culture industry such as performance, show and exhibition. Thus, this builds up the foundation to improve visitor's participation in exhibition and bring about development of exhibition industry by raising visitor's interest.

박선희,배종환,Park, Seon-Hui,Bae, Jong-Hwan 한국사물인터넷학회 2020 한국사물인터넷학회 논문지 Vol.6 No.4

본 논문은 스마트 팩토리(Smart Factory) 디지털 트윈(Digital Twin) 구축을 위해서 다양한 산업용 센서(IoT/비 IoT)로부터 센서데이터를 획득하기 위한 표준 노드(Node)를 생성하고 그룹별/공정별 존(Zone)을 연동하여 상호호환적인 데이터의 교환 기능을 제공함으로써 데이터의 안정성을 확보하고 스마트 팩토리의 디지털 트윈(Digital Twin)을 위한 효과적인 존 마스터(Zone Master) 플랫폼 구축 방안을 제시하였다. 존 마스터(Zone Master) 플랫폼의 Process는 독립된 시스템 간의 센서 객체 및 센서 상호작용이 어떻게 수행하는지를 정의해 주기 위한 인터페이스 명세를 포함하고 있으며 고유의 데이터 교환 규칙에 대한 개별 정책들을 수행하고 있다. 존 마스터 플랫폼 프로세서의 실행 통제를 위한 인터페이스는 시스템관리, 자료교환의 협상(publish-subscribe)을 위한 선언 관리, 센서 객체의 등록 및 상태 정보를 통신하기 위한 객체 관리, 속성 소유권 공유를 위한 소유권 관리, 데이터 동기화를 위한 시간 관리, 데이터 교환에 대한 Route 정보를 위한 자료 분배 관리를 제공한다. This paper creates a standard node for acquiring sensor data from various industrial sensors (IoT/non-IoT) for the establishment of Smart Factory Digital Twin, and provides inter-compatible data by linking zones by group/process to secure data stability and to ensure the digital twin (Digital Twin) of Smart Factory. The process of the Zone Master platform contains interface specifications to define sensor objects and how sensor interactions between independent systems are performed and carries out individual policies for unique data exchange rules. The interface for execution control of the Zone Master Platform processor provides system management, declaration management for public-subscribe, object management for registering and communicating status information of sensor objects, ownership management for property ownership sharing, time management for data synchronization, and data distribution management for Route information on data exchange.

HLA 패더레이트 개발을 위한 ROM 프레임워크 설계 및 구현

김대석,배종환,류재철,Kim, Dae-Seog,Bae, Jong-Hwan,Ryou, Jae-Cheol 한국정보처리학회 2002 정보처리학회논문지D Vol.9 No.6

패더레이션의 개선 가능성은 구성된 멤버 패더레이트들에게 유연성과 적응성을 요구하게 된다. 더욱이 비 연동화 모델을 HLA(High Level Architecture) 패더레이트로 개발하고 이를 가변적인 특성 패더레이션에 연동되도록 하기 위해서는 더 많은 시간과 노력이 요구된다. 본 연구에서는 이러한 문제를 해결하는 방법으로 ROM(RTI Object Model) 프레임워크를 설계하고 구현하는 방법을 제시하였다. ROM은 RTI(Run-Time Infrastructure) 프로그래밍과 패더레이트 시뮬레이션 프로그래밍을 완벽하게 분리시킴으로써 가변성 있는 FOM을 지원할 수 있는 HLA 패더레이트 개발을 비용과 생산성 측면에서 획기적인 효율을 제공하게 되었다. 즉 ROM은 RTI와 패더레이트 사이에 RTI 서비스를 관리하는 관리 계층과 실제로 객체 및 강호작용을 갱신 또는 반영하는 Foundation Class 계층을 두어 패더레이트 개발자들에게 보다 일반화된 HLA 서비스 사용환경을 제공해주고 동시에 반복적이고 하위수준의 RTI 프로그래밍을 자동화 할 수 있게 하였다. Possibility of federation improvement requires flexibility and adaptability of member federates. Moreover, to develop and convert a non-HLA(High Level Architecture) compliant model as a HLA federate and allow this federate to be integrated with a changeable federation, more time and efforts will be necessary. In this research, I proposed a method to design and implement a ROM (RTI Object Model) Framework as a solution to this problem. ROM completely separates RTI (Run-Time Infrastructure) programming and simulation programming therefore providing epochal efficiencies in cost and productivity to the development a HLA federate that supports a changeable FOM. That is, ROM contains two layers : 1) a management layer that manages RTI services between the RTI and the federate and 2) a Foundation Class layer that actually updates/reflects objects and interactions. These two layers allow federate developers to use more generalized HLA services and automates the iterative, low-level RTI programming process.
