There is no processing function at agrifood marketing in Korea. Because of long term separation between food processing and domestic agricultural products, processing have not concerns in agricultural economists. Nowadays, many kinds of processed foods, that is, kimchi, beverage, red pepper powder, et al, are produced from domestic raw materials, but, processing function are still excluded from agrifood marketing. Exclusion of processing gave rise to economic loss in total agricultural marketing cost. For example, red peppers are dried at individual farm houses before processing, and they are redried at factory during the red pepper powder processing. If processing function were included in agrifood marketing area, one time drying at factory is enough for the red pepper powder production, and drying cost could be saved. It is necessary to include processing function in agrifood marketing for the efficient and effective agrifood distribution in Korea.

Distributed renewable energy generation is lack of intelligent information processing and decision-making section. The above problems can be solved effectively by the means of intelligent information processing technology based on the dynamic structure of multi-agent for distributed renewable energy. In order to solve the problems of less data and poor information, this paper puts forward fuzzy hyperbolic model and attempts to use dynamic intelligent information processing technology based on multi-agent to change the unreliable, inaccurate information into be full, reliable and accurate. And then the information we have obtained could be intelligent fitted, filtered and decided. The self-organizing self-learning and reasoning ability of multi-agent are considered when the information processing. The intelligent information processing section is comprised of three layers and two kinds of agents. The two kinds of agents are Bus Agents and Coordination Agents, and the three structural layers are the data layer, the filter layer and the policy making layer. Moreover the information have been processed could be utilized.

김현종,길명선,문양세 한국정보과학회 2023 정보과학회논문지 Vol.50 No.4

Graph data, which values the relationship of each object, is widely used for new rules or association analysis that cannot be found in relational databases. However, there is a limit to high-speed processing due to its complex structure and massive data size. In this paper, we propose PIGraph (Pregel and InfiniBand-based Graph processing engine) to improve the processing performance of graph data. PIGraph is an advanced graph processing engine based on Pregel, which is a representative graph processing model. PIGraph supports the distributed parallel structure using InfiniBand and RDMA (Remote Direct Memory Access) technology to reduce the management complexity of distributed graph processing. In particular, PIGraph improves the processing performance of graph data by optimizing the RDMA communication with segment-based transmissions. Experimental results show that PIGraph improves the processing time by up to 190% compared to Apache Giraph. 각 객체의 관계를 중시하는 그래프 데이터는 관계형 데이터베이스에서는 찾아낼 수 없는 새로운 규칙이나 연관성 분석에 많이 사용되지만, 복잡한 구조와 방대한 양으로 인해 빠른 처리에는 한계가 있다. 본 논문에서는 이러한 그래프 데이터 처리의 성능 향상을 위해 PIGraph(Pregel and InfiniBand- based Graph processing engine)를 제안한다. PIGraph는 대표적인 그래프 처리 모델인 Pregel 기반 그래프 처리 엔진이다. PIGraph는 분산 그래프 처리의 관리 복잡도 감소를 위해 인피니밴드와 RDMA (Remote Direct Memory Access) 기술을 활용한 분산 병렬 구조를 지원한다. 특히, 세그먼트 단위 전송으로 RDMA 통신을 최적화하여 그래프 데이터의 처리 성능 한계를 개선한다. 성능 평가 결과, PIGraph가 비교 시스템인 Apache Giraph에 비해 최대 190% 이상 빠른 처리 시간을 보임을 확인하였다.

The ICT(information & communication technology) led to a dramatic change of floral distribution service, a phase of competition between wholesales and retail stores, and distribution channels in floral industry. It was expected that a role of the intermediaries in this industry would have reduced due to the improvement of transaction process by ICT. However, the ICT made to overcome a regional limit of the floral retail distribution service leading to an increase in sales and enlargement of the stores. And even it made possible to bring out another type of intermediaries such as private associations. This case study focuses on what kinds of efforts the floral wholesale distributors have made to enable a distribution process more smoothly between the wholesale distributors and retail stores through the information system, and what the failure factors in adopting the information system have been. This paper is also to examine how the wholesale distributors have changed themselves to gain dominant positions in distribution channels. As a result of the study, it was found that the intermediaries mostly failed in successfully achieving the distribution channel innovation through the information system because of several main reasons. FLOMARKET Inc. tried to innovate a distribution channel to obtain high quality goods through consolidating a wholesale distribution market in that segregated both floral joint market from free markets. after implementing the information system with consideration of the failure factors, FLOMARKET Inc. was able to minimize goods in stock and make a major purchase of various goods. In addition, it made a possible pre-ordering process and an exact calculation of purchasing goods so they could provide their products with market price in real time, which helped for the company to gain credits from their customers. Also, FLOMARKET Inc. established the information system which well suited to its business stage in order to deal with a rapidly changing distribution environment. It's so obvious that the transaction processing system of FLOMARKET Inc. definitely helped to share information among traders more seamlessly and smoothly in realtime, standardize goods, and make a transaction process clearer. Besides, the transaction information helped the wholesale distributors and retail stores to make more strategic decisions in their business because through the system they enabled to gather the marketing intelligence information more easily and convenient. If we understand that the floral distribution market is characterized by the low IT- based industry, it's worth to examine a case study proving that the information system actually increases the productivity of the transaction process in the floral industry.

조이상,김진홍 한국지식정보기술학회 2020 한국지식정보기술학회 논문지 Vol.15 No.6

Nowaday, towards adopting big data processing system has increased and it is commonly seen in every aspect of life. For this, the problem of finding connected components in undirected graphs has been well studied, and it is an essential pre-processing step to many graph computations, and a fundamental task in graph analytics applications. Recently, it has been a main area of interest in the large graph processing. However, much of the research has focused on solving the problem using High Performance Computers. In large distributed systems, the MapReduce framework dominates the processing of big data, and has been used for finding connected components in big graphs although iterative processing is not directly supported in MapReduce. Current big data processing systems have developed into supporting iterative processing and providing additional features other than MapReduce. This research investigates how to enhance the performance of finding connected components algorithm for large graph in distributed processing system. It uses the approach to considering the graph degree property in choosing the component identifier, reviewing how this can affect the efficiency of the algorithm. In the design of our proposed algorithm features provided by current new processing systems such as moving the computation more toward the data partition in Spark framework model are integrated.

Distributed computing helps to efficiently store and process large data on a cluster of multiple machines. The performance of distributed computing is greatly influenced depending on the state of the servers constituting the distributed system. In this paper, we propose a self-diagnosis system that collects log data in a distributed system, detects anomalies and visualizes the results in real time. First, we divide the self-diagnosis process into five stages: collecting, delivering, analyzing, storing, and visualizing stages. Next, we design a real-time self-diagnosis system that meets the goals of real-time, scalability, and high availability. The proposed system is based on Apache Flume, Apache Kafka, and Apache Storm, which are representative real-time distributed techniques. In addition, we use simple but effective moving average and 3-sigma based anomaly detection technique to minimize the delay of log data processing during the self-diagnosis process. Through the results of this paper, we can construct a distributed real-time self-diagnosis solution that can diagnose server status in real time in a complicated distributed system. 분산 컴퓨팅이란 다수의 서버로 구성된 분산 시스템에서 데이터를 효율적으로 저장 및 처리하는 기술이다. 따라서 분산 시스템을 구성하는 서버의 상태에 따라 분산 컴퓨팅의 성능에 큰 영향을 미친다. 본 논문은 분산 시스템에서 실시간으로 발생하는 시스템 자원의 로그 데이터를 수집하고 이상을 탐지하여 결과를 시각화하는 자가 진단 시스템을 제안한다. 먼저, 자가 진단 과정을 수집, 전달, 분석, 저장, 시각화의 다섯 단계로 구분한다. 다음으로, 자가 진단 과정이 실시간성, 확장성, 고가용성의 목표를 만족하도록 실시간 자가 진단 시스템을 설계한다. 본 시스템은 대표적인 실시간 분산 기술인 Apache Flume, Apache Kafka, Apache Storm을 기반으로 구현되어 실시간성, 확장성, 고가용성의 세 가지 목표를 만족할 수 있다. 또한, 자가 진단 과정에서 로그 데이터 처리의 지연을 최소화하도록 간단하지만 효과적인 이동 평균 및 3-시그마 기반 이상 탐지 기법을 사용한다. 본 논문의 결과를 통해, 분산 시스템 내에서 서버 상태를 실시간으로 진단할 수 있는 분산 실시간 자가 진단 시스템을 구축할 수 있다.

Energy-Efficient Distributed Spatial Join Processing in Wireless Sensor Networks

KIM, Min Soo,SON, Jin Hyun,KIM, Ju Wan,KIM, Myoung Ho The Institute of Electronics, Information and Comm 2010 IEICE transactions on information and systems Vol.93 No.6

<P>In the area of wireless sensor networks, the efficient spatial query processing based on the locations of sensor nodes is required. Especially, spatial queries on two sensor networks need a distributed spatial join processing among the sensor networks. Because the distributed spatial join processing causes lots of wireless transmissions in accessing sensor nodes of two sensor networks, our goal of this paper is to reduce the wireless transmissions for the energy efficiency of sensor nodes. In this paper, we propose an energy-efficient distributed spatial join algorithm on two heterogeneous sensor networks, which performs in-network spatial join processing. To optimize the in-network processing, we also propose a Grid-based Rectangle tree (GR-tree) and a grid-based approximation function. The GR-tree reduces the wireless transmissions by supporting a distributed spatial search for sensor nodes. The grid-based approximation function reduces the wireless transmissions by reducing the volume of spatial query objects which should be pushed down to sensor nodes. Finally, we compare naïve and existing approaches through extensive experiments and clarify our approach's distinguished features.</P>

본 연구에서는 철근의 인장시험에서 변형률에 대한 상세 측정을 위하여 이미지 프로세싱을 이용하고, 변형률 분포와 넥킹구간을 평가하였다. 이미지 프로세싱 방법으로는 기존의 회색조영상을 이용한 방법이 아닌 칼라영상의 색상정보를 분석하여, 원하는 타겟과 가장 일 치하는 영역과 그 외의 영역으로 구분하여 이진영상으로 변환하는 방법을 사용하였다. 변환된 이진영상에서 개별 타겟들의 도심점을 산출한 후 각 도심점의 상대변위값을 변형률로 환산하였다. 인장실험은 ASTM A615 기준으로 제작된 grade 60 철근 중 D22와 D29에 대해서 시험을 수행하였다. 이미지 프로세싱을 이용하여 계측된 변형률 결과를 기존 변형률 게이지를 이용하여 계측한 결과와 비교하여, 본 연구에서 사용한 이미지 프로세싱 방법에 대해서 검증하였다. 이미지 프로세싱을 이용하여 초기 탄성구간의 변형률 뿐만 아니라 넥킹구간에서 발생한 0.5 (50%) 이상의 변형률도 계측이 가능한 것을 확인하였다. 본 연구결과 이미지 프로세싱을 통하여 기존 변형률 게이지의 계측한계를 극복가능 하고, 다양한 지점에서 자유롭게 계측할 수 있음을 알 수 있었다. In this study, measurements were conducted by image processing to do an in-depth evaluation of strain of rebar in a uniaxial tension test. The distribution of strain and the necking region were evaluated. The image processing is used to analyze the color information of a colored image, so that the parts consistent with desired targets can be distinguished from the other parts. After this process, the image was converted to a binary one. Centroids of each target region are obtained in the binary images. After repeating such process on the images from starting point to the finishing point of the test, elongation between targets is calculated based on the centroid of each target. The tensile test were conducted on grade 60 #7(D22) and #9(D29) rebars fabricated in accordance with ASTM A615 standards. Strain results from image processing were compared to the results from a conventional strain gauge, in order to see the validity of the image processing. With the image processing, the measuring was possible in not only the initial elastic region but also the necking region of more than 0.5(50%) strain. The image processing can remove the measuring limits as long as the targets can be video recorded. It also can measure strain at various spots because the targets can easily be attached and detached. Thus it is concluded that the image processing helps overcome limits in strain measuring and will be used in various ways.

Box-Cox변환을 이용한 다변량 공정능력 분석

문혜진(Hye-Jin Moon),정영배(Young-Bae Chung) 한국산업경영시스템학회 2019 한국산업경영시스템학회지 Vol.42 No.2

The process control methods based on the statistical analysis apply the analysis method or mathematical model under the assumption that the process characteristic is normally distributed. However, the distribution of data collected by the automatic measurement system in real time is often not followed by normal distribution. As the statistical analysis tools, the process capability index (PCI) has been used a lot as a measure of process capability analysis in the production site. However, PCI has been usually used without checking the normality test for the process data. Even though the normality assumption is violated, if the analysis method under the assumption of the normal distribution is performed, this will be an incorrect result and take a wrong action. When the normality assumption is violated, we can transform the non-normal data into the normal data by using an appropriate normal transformation method. There are various methods of the normal transformation. In this paper, we consider the Box-Cox transformation among them. Hence, the purpose of the study is to expand the analysis method for the multivariate process capability index using Box-Cox transformation. This study proposes the multivariate process capability index to be able to use according to both methodologies whether data is normally distributed or not. Through the computational examples, we compare and discuss the multivariate process capability index between before and after Box-Cox transformation when the process data is not normally distributed.
