This study was conducted to develop a traceability system for systematic animal identifi- cation to increase efficiency of animal production, post production and processing to ensure that quality and sanitary meat products reach the consumers of the entire country. The new animal identification traceability system was designed for easy management, data collection and storage considering bar code, registration number and farm number.Specifically the system aimed 1) To provide standard radio frequency technology identification (RF-ID) for livestock management, standard of ear tag, microchip and ear tag identification equipment, 2) To guarantee meat product label thereby safeguarding the consumers 3) To give incentives to farmers for producing quality meat products and 4) To provide unified system for national livestock management.Results of the research which started in July 2003 which was used by several farmers’ cooperatives and Department Store revealed the feasibility of using the RF-ID system although much will be done to conform to global nomenclatures.

This study aimed to examine whether the polygenic profile of ACE ID and ACTN3 R577X polymorphisms is associated with muscle power performance in Korean athletes. For this study, 106 top-class power athletes (top-class group), 158 elite power athletes (elite-class group), and 676 healthy adults (control) aged 18-39 yrs were recruited and their genotypes were analyzed. The top-class group showed higher frequencies of the II genotype and I allele in ACE, as well as higher frequencies of the RR genotype and R allele in ACTN3 (top-class vs. control: 41.4% vs. 32.1% for II genotype, 67.1% vs. 57.7% for I allele, p<0.05; 42.3% vs. 29.0% for RR genotype, 65.3% vs. 54.8% for I allele, p<0.05). In the polygenic profile, the top-class group had significantly higher frequencies of combined-II/ID+RR/RX genotype than the control group (top-class vs. control: 82.9% vs. 66.7% for II/ID+RR/RX, p<0.05), and there was even a sharp increase in total genotype score (TGS) in this group compared to the elite-class and control groups ($66{\pm}0.9$ vs. $58{\pm}1.9$ vs. $56{\pm}2.3$, p<0.05). The combined-II/ID+RR/RX genotype showed the possibility of succussion in the top-class muscle power performance with an odds ratio of 2.3 (CI:1.4-4.1, p<0.05). These results suggested that ACE and ACTN3 need to interact with each other to affect muscle-power performance in an additive form. Furthermore, the polygenic profile of ACE and ACTN3 can predict muscle performance with high success in a homogeneous dominant combined genotype (II/ID+RR/RX). A further study could identify and combine other genes into ACE and ACTN3 for muscle strength.

In this study, a system to increase the expressiveness of existing standard terminology using three-dimensional (3D) data is designed. We analyze the existing medical terminology system by searching the reference literature and perform an expert group focus survey. A human body image is generated using a 3D modeling tool. Then, the anatomical position of the human body is mapped to the 3D coordinates' identification (ID) and metadata. We define the term to represent the 3D human body position in a total of 12 categories, including semantic terminology entity and semantic disorder. The Blender and 3ds Max programs are used to create the 3D model from medical imaging data. The generated 3D human body model is expressed by the ID of the coordinate type (x, y, and z axes) based on the anatomical position and mapped to the semantic entity including the meaning. We propose a system of standard terminology enabling integration and utilization of the 3D human body model, coordinates (ID), and metadata. In the future, through cooperation with the Electronic Health Record system, we will contribute to clinical research to generate higher-quality big data.

In 3GPP LTE system downlink, PSS (primary synchronization signal) and SSS (secondary synchronization signal) sequences are used for initial cell search and synchronization. UE (user equipment) detects slot timing, frequency offset, and cell ID by using PSS. After that it should detect frame timing, cell group ID, and CP length by using SSS. But in 3GPP LTE, there are two kinds of CP length, so we should operate FFT twice. In this paper, to minimize SSS detection complexity in cell searcher, we propose a CP length pre-decision algorithm that reduces the arithmetical complexity by half at most, with negligible performance degradation.

데이터 3법 시대에 접어들면서 기업들에는 가명화된 개인정보를 활용할 수 있는 길이 열렸다. 하지만 현 데이터 3법은 데이터를 생성하고 유통하며 활용할 기업들의 책임과 혜택에 내용이 맞춰져 있어 아쉬운 감이 있다. 개인의 기본권을 보장하면서도 마이데이터 유통 및 활용을 도울 방법은 없을까? 본 논문에서는 데이터의 주체인 개인이 데이터 주권을 행사하고 실질적인 혜택을 받는 마이데이터 서비스의 활성화를 위한 ID 관리 기술로 블록체인 기반 분산 ID(Decentralized Identification, DID)를 제안하고, DID 수용의도에 영향을 마치는 요인을 연구함으로써 마이데이터 서비스 개발 활성화를 위한 정책적, 실무적 시사점을 도출하고자 한다.

In this paper, high throughput method is studied to provide floating objects with broadband service as ship by using satellite. In recent, satellite broadcastings standard is based on DVB-S3 for communication service using wireless device on navigation communication by satellite. LDPC codes are iterative coding algorithm proposed in DVB-S3. In this paper, FTN technique is applied to LDPC codes with 8-PSK modulation and then present the method to alleviate performance degradation due to FTN through BICM-ID. BICM-ID is the method to improve performance by calculating a new LLR from hard-decision value of decoder output. DVB-S2 system with 8-PSK modulation and FTN technique based on iterative decoding had a better performance than DVB-S2 with 8-PSK modulation and FTN technique over Gaussian channels.

In this paper, we design and implement a product information guidance system Based on BLE beacons. This system is designed to provide various functions such as contactless entrance service through mobile ticket, seat guidance service, event push service, content push service, and public service. This system consists of three modules: a beacon recognition module, a server linkage module, and a content transmission module. The beacon recognition module implements a function of transmitting a specific ID of a nearby beacon when a customer with a smartphone approaches the available service area. The server linkage module recognizes the beacon ID value, transfers it to the server, and implements the function to check the location of the server having the ID. The content transmission module implements a function of transmitting event or service information set at a corresponding location to a smartphone. The beacon-based product information guidance system implemented in this paper has the advantage of being able to quickly and easily implement various product information guidance systems.

Mobile agent system comes into the spotlight since it contributes largely to mobile computing on distributed network environment. However, this system has a number of significant security Problems. In this Paper, we analyze suity attacks to mobile agent system Presented by NIST[3]. In order to protect this system from them, we suggest a security protocol for mobile agent system by employing R based key distribution and digital multi-signature scheme. To solve these problems described in NIST, securities for mobile agent and agent platform shouid be accomplished. Comparing with other protocols, our protocol performs both of these securities, while other protocols mentioned only one of them. Proposed Protocol satisfies simplicity of key management, providing security service such as confidentiality, integrity, authentication and preventing reputation, liveness guarantee, protection of excution-result data and preventing replay attack. Furthermore, it is designed to detect message modification immediately by verifying each step of agent execution at a corresponding server.
