  • With the proliferation of artificial intelligence technology, it is becoming important to obtain, store, and utilize scientific data in research and science sectors. A number of methods for extracting meaningful objects such as graphs and tables from research articles have been proposed to eventually obtain scientific data. Existing extraction methods using heuristic approaches are hardly applicable to electronic documents having heterogeneous manuscript formats because they are designed to work properly for some targeted manuscripts. This paper proposes a prototype of an object extraction system which exploits a recent deep-learning technology so as to overcome the inflexibility of the heuristic approaches. We implemented our trained model, based on the Faster R-CNN algorithm, using the Google TensorFlow Object Detection API and also composed an annotated data set from 100 research articles for training and evaluation. Finally, a performance evaluation shows that the proposed system outperforms a comparator adopting heuristic approaches by 5.2%.

  • Web Service which consists of SOAP, WSDL and UDDI is a software system that enables interactions of heterogeneous systems on networks with standardized XML message. Especially, UDDI is a registry for supporting the registration of a service by service publisher and discovery of a service by service requester. The preliminary studies are just about publishing and searching services. It presents the researches about UDDI study for improvement of searching a service and extended UDDI design for improvement of reusability with service components aspects. In this paper, we suggest not only features about publishing and searching services of existing UDDI system but also novel UDDI data structures and API for a reusable service model. In addition, we design and implement an extended UDDI system for publishing and finding the reusable services. Therefore, by using proposed UDDI systems, service developers reduce development costs and time through developing a service application reusing the already implemented services. In addition, it can expect to ensure the quality of services by reusing the proven services.

  • For supporting Interoperability among heterogeneous data sources in different geographic information systems, it is required to use open API like OGIS OLE DB Proposed in OGC. The OLE/COM Implementation Specification of OGIS only provides interfaces to discover and access spatial data, but does not support interfaces for updating distributed spatial data. To solve this problem, we propose and add interfaces for updating spatial objects distributed over heterogeneous data sources and examining the consistency of spatial relationships between updated objects. We also devise a 2-phase commit protocol based on spatial relationships in order to guarantee the consistency of updated objects. To justify the update scheme using the proposed Interfaces and 2-phase commit prototype we design and implement a prototype system for updating distributed spatial objects.

  • As the interest of things to the Internet increases, the market of IoT grows larger and devices and protocols related with IoT are evolving.As these IoT devices and protocols evolve, There was a problem with interoperability. As a result, market and standard of IoT are confused, and communication between objects and objects is being hindered by different platforms. Currently, various IoT platforms are being developed and interoperability with heterogeneous platforms is under study, but the protocols used on each platform are limited and designed to have no generalized structure. Therefore, in this paper, we analyze services of HTTP, CoAP, and MQTT protocols, which are typical in the Internet market, and design services that enable selective protocol communication. We also design resources that apply the RESTful API to generalize platform usage. and We implemented the platform through database modeling for quick processing and safety of the collected data. Through this process, devices communicating with different protocols can be interworked on one platform and We propose a "generalized selective protocol based Internet object data collecting platform" that can be applied to various protocols.

  • Bacteriocins are classified as proteins which are produced by heterogeneous groups of bacteria, having and antimicrobial effect of the closely related organisms. Recently, bacteriocins derived from lactic acid bacteria and other food-related organisms have been the subject of much research on potential food biopreservatives. The goal of this study was to screen and characterize the bacteriocinogenic lactic acid bacteria from Jeot-gal(commercial fermented fish foods). All bacteriocinogenic isolates were identified as lactic acid bacteria. Isolates NK24, NK34, and SA72 were tentatively identified as Lactobacillus brevis, according to the API 50 CHL kit database. All antimicrobial substances produced from four lactic acid bacteria isolates completely lost their antibacterial activity after being treated with some proteases, indicating to their proteinaceous nature. The bacteriocin produced from isolates NK24, NK34, and SA72 showed a broad spectrum of activity when compared to those produced from isolate SA131. All bacteriocins isolated during the course of this study showed a bactericidal mode of inhibition.

  • The current system upon which a variety of programs are in operation has continuously expanded its domain from conventional single-core and multi-core system to many-core and heterogeneous system. However, existing researches have focused mostly on parallelizing programs based CUDA framework and rarely on AMD based GCN-GPU optimization. In light of the aforementioned problems, our study focuses on the optimization techniques of the GCN architecture in a GPGPU environment and achieves a performance improvement. Specifically, by using performance techniques we propose, we have reduced more then 30% of the computation time of matrix multiplication and convolution algorithm in GPGPU. Also, we increase the kernel throughput by more then 40%.

  • In this paper, we propose S/W framework for health care robot based on OSGI middleware. Most healthcare robot developed independently. Therefore most module duplicately developed. However It's not efficient. In this paper we propose S/W framework for healthcare robot that can provide common module for health care robot and can apply heterogeneous robot. By using this S/W framework, we can enhance reusability of s/w module and can provide flexible and efficient development environment.

  • 최근 인터넷의 발달과 함께 웹을 기반으로 하는 클라이언트-서버 분산 구조의 웹서비스 시스템 구조가 점차 확산되고 있다. 게다가, 최근에는 스마트폰을 이용한 스마트폰 애플리케이션이 대중화 되면서, 웹 서비스의 활용이 점차 확대되는 추세이다. 웹을 기반으로 클라이언트와 서버 사이에 통신을 하기 위해서는 원격 프로시저를 정의한 인터페이스가 규정되어야 하며, 기존에는 W3C에서 정의한 WSDL를 사용하여 웹서비스를 기술하곤 하였다. 그러나, 이와 같은 기존의 웹서비스 기술 및 사용방법은 그 구성이 복잡하고 오버헤드가 큰 이유로 널리 활용되지 못하였다. 최근에는 스마트폰이 대중화 되면서 REST 웹서비스의 활용이 확산되는 추세다. SOAP 기반 웹서비스에 대해서는 서비스 조합에 대해서 충분히 다루어 졌으며, 어느정도 정리된 연구분야이다. SOAP 웹서비스는 기계가 인식하기 쉽도록 엄격한 규약과 인터페이스를 정의한 것이기 때문이다. 반면, REST 웹서비스는 최근 이기종(heterogeneous) 시스템 통합 및 스마트폰에서 서버 측 데이터를 접근하는 가장 유리하고 편리한 방법이다. 따라서, 그 활용방법에 대하여 많은 수요가 발생하고 있으나, 일반적으로 잘 소개되어 있지 않으므로 본 논문에서 REST Web Service Open API의 스마트폰 애플리케이션 개발의 활용방법을 소개한다.

  • Recently, supercomputer has been increasingly adopted as a computing environment for scientific simulation as well as education, healthcare and national defence. Especially, supercomputing system with heterogeneous computing resources is gaining resurgence of interest as a next-generation problem solving environment, allowing theoretical and/or experimental research in various fields to be free of time and spatial limits. However, traditional supercomputing services have only been handled through a simple form of command-line based console, which leads to the critical limit of accessibility and usability of heterogeneous computing resources. To address this problem, in this paper, we provide the design and implementation of web-based HPC (High Performance Computing) job management framework for computational scientific simulation. The proposed framework has highly extensible design principles, providing the abstraction interfaces of job scheduler (as well as bundle scheduler plug-ins for LoadLeveler, Sun Grid Engine, OpenPBS scheduler) in order to easily incorporate the broad spectrum of heterogeneous computing resources such as cluster, computing cloud and grid. We also present the detailed specification of HTTP standard based RESTful endpoints, which manage simulation job's life-cycles such as job creation, submission, control and status monitoring, etc., enabling various 3rd-party applications to be newly created on top of the proposed framework.
