모든 사물이 통신으로 연결되는 사물인터넷(IoT) 시대가 도래 하면서, IoT센서를 통한 데이터 시각화에 대한 요구가 증가 하고 있다. 본 연구에서는 전문적인 지식이 없는 사람도 쉽게 방대한 센서 데이터를 저장, 수집 후 쉽게 데이터 시각화할 수 있는 시스템을 구성 하였다. 본 논문에서는 데이터 시각화를 접근성이 용이한 웹 브라우저에서 구현하였고, 웹 브라우저에서 이를 구현하기 위해서는 웹의 다양한 비표준 플러그인(Flash, SilverLight, ActiveX 등)을 사용해야하는 불편함있다. 이를 개선하기 위해 HTML5, CSS, Javascript를 사용해 플러그인을 설치하지 않고 초음파 센서를 사용한 데이터의 실시간 차트 구현을 하였다. 본연구의 결과는 향후, 초음파 센서데이터를 활용한 전후방 장애물 감지 센서, 도난 경보 시스템, IoT센서 데이터 시각화 서비스 등에 활용 될 것으로 기대된다.

A lot of efforts have been made to develop a new technology for efficient distance education based on a powerful Internet service like World Wide Web. By developed distance education systems, we can study something we want at anytime and anywhere. However in spite of the excellent achievements we have made, something insufficient still is remained. Distance education methods only depending on static homepages or voices and simple drawings may be insufficient to support as much effects as in real class. So it is necessary to develop a new method for teaching students more feasibly and efficiently In this paper, we try to design and implement a lecture authoring system that offers effective distance education with voices, animations, camera images, drawings and etc.. We can expect the designed system can give more efficient education effects like a face-to-face lecture in real class. The enclosed function of intense compression enables to transmit the lectures more speedily. Besides it has caption processing function to serve additional informations to students with caption texts, messages and hyperlinks.

Recently many applications are being developed as web technologies are evolved rapidly, but the development emthodology and quality improvement speed of the web apllications is not so. The creations of Most web applications have developed depending on the developer's knowledge and experience without a systematic development methodologies. But the web-based application systems require the various developing gechniques and the rich developing methodogies for a design process. This paper applies the UML(Unified Modeling Language) supporting an object-oriented development methodology to the design and implementation of a mobile customer management system. That is, it appliesthe UML to the system modeling based on a story board and a requirement specification at the web development of the similar web applications. Applying UML to this system achieved the analysis and the design of an web application effciently.

최근 질병 분석 및 신약을 개발하기 위한 단백질에 대한 연구는 생명 공학의 큰 테마 중 하나이다. 질병 및 단백질 데이터를 분석하기 위한 연구는 대용량의 데이터 처리를 요구하기 때문에 과거 실험을 통해 접근하던 방식에서 벗어나 최근 IT 기술의 결합을 통해 다양한 실험 데이터를 공유하고, 연계함으로써 연구를 가속화하고 있다. 하지만 생명 공학 연구자에게 있어서 IT 지식을 기반을 둔 단백질 분석 도구를 다루는데 많은 어려움이 있다. 이러한 문제를 해결하고자, IT 연구자와 생명 공학 연구자의 협업을 통한 데이터 분석 도구를 개발이 폭넓게 시도되고 있지만, 연구자 간의 협업을 도울 수 있는 통합 인프라는 전무한 실정이다. 본 논문에서는 IT 연구자와 생명 공학 연구자의 협업을 위한 인프라로서 컴포넌트 기반의 질병 및 단백질 데이터 분석 시스템을 설계하고 구현한다.

In this paper, we built an Object Oriented Framework for Web collaboration system which contains high level analysis information and design knowledge for java applets and applications that enable web clients to communicate and collaborate each other. Components of framework contain design information, source codes and executable codes for reuse. We had defined a development method for domain framework in related works and built a web collaboration system framework following it. We defined subsystem of web collaboration system for the communication and collaboration between web clients. We also BBS, Q&A system, board service system for the communication and collaboration between web clients. We also developed visual tools for framework usability : source code generator, class editor, knowledge supporting tools.

This study was conducted to identify trends and knowledge structures associated with recent trends in Korean tourism from 2010 to 2015 using keyword data. To accomplish this, we constructed a network using keywords extracted from KCI journals. We then made a matrix describing the relationships between rows as papers and columns as keywords. A keyword network showed the connectivity of papers that have included one or more of the same keywords. Major keywords were then extracted using the cosine similarity between co-occurring keywords and components were analyzed to understand research trends and knowledge structure. The results revealed that subjects of tourism research have changed rapidly and variously. A few topics related to 'organization-employee' were major trends for several years, but intrinsic and extrinsic factors have been further subdivided and employees of specific fields have been targeted as subjects of research. Component analysis is useful for analyzing concrete research topics and the relationships between them. The results of this study will be useful for researchers attempting to identify new topics.

The research on protein for the diseases analysis and the new medicines development is one of the most important themes in biotechnology. Since the analysis on diseases and protein needs to handle a large scale of data, we don't use the way to approach it by the experiments anymore. In recent, we have accelerated the research on diseases and protein analysis by sharing and connecting the various experimental data by combining the biotechnology with the IT technology. However, many biotechnology researchers have difficulty in handling the protein analysis tools based on the IT knowledge. In order to solve such problems, data analysis tools through the cooperation between IT researchers and biologists have been developed. However, the existing data analysis tools still have the problems that it is very hard for biologists to extend their functions and to use them. In this paper, we design and implement an effective analysis system for diseases and protein based on components that alleviates the problems of the existing data analysis systems.

The purpose of the study was to investigate the relationship between the communication status in group and the semantic network of science gifted students. Seven small groups, 5 members in each, participated in small group activities, in which they discussed the calculation of earth density. Both the communication status in group and the semantic network of science gifted students were analyzed using KrKwic, Ucinet 6.0 for Windows. As a result, the semantic network of prime movers in group represented more frequently used words, lesser rate of component, and higher density than that of out lookers. It means that the prime movers have coherent knowledge compared to out lookers, and they output more knowledge for problem solving than out lookers. Therefore, the results of this study may be applied to evaluating the cognitive level of science gifted students and group organization for small group activity.

국내외 대규모 산업시설은 유해물질과 직 간접적으로 밀접하게 관련되어 유해물질 누출사고는 막대한 물적, 인적 피해를 발생시키며 누출물질, 저장시설, 대기 상태에 따라 유해물질 확산 속도 및 범위가 다르기 때문에 이를 예측하는 대기확산 시스템이 필요하다. 또한 기존의 대기확산 시스템은 산업시설 구조물 설계 단계에서 안전성을 확인하는 시뮬레이션용으로 사용되었기 때문에 누출사고 발생 시 즉각적인 처리와 대응이 어려우며 전문적 지식수준의 사용자 입력을 요구한다. 본 논문은 에너지 플랜트 환경의 특수성과 효율성을 고려하여 운영 중인 시설에 적용 가능한 대기확산 시스템 연구를 목적으로 한다. 이를 위하여 신속하고 효율적인 대기확산 모델을 선정 정의하고 융통성 있는 대기확산 시스템의 구성요소를 컴포넌트화하여 구현하였으며 사고 발생 시 빠르게 피해범위를 예측할 수 있는 실시간 대기확산 시스템 설계 방안을 제시하였다.

In this paper, we implement Microsoft COM software modules for elliptic curve cryptographic applications and analyze its performance. The implemented COM software modules support all elliptic curve key exchange protocols and elliptic curve digital signature algorithm in IEEE 1363 finite fields GF(p) and GF(2m). Since the implemented software modules intend to focus on a component-based software development method, and thus it have a higher productivity and take systematic characteristics to be open outward and to be standardized. Accordingly, it enable a software to be developed easier and faster rather than a method using C library. In addition it support the Microsoft COM interface, we can easily implement secure software applications based on elliptic curve cryptographic algorithms.
