  • 최근 많이 주목을 받고 있는 웹 2.0은 사용자의 참여, 개방, 네트워크 효과에 기반하여 누구나 데이터를 생산하고 공유할 수 있는 사용자 중심의 인터넷 환경이다. openAPI는 웹 2.0의 근본 개념인 데이터의 개방 및 공유를 구현할 수 있는 핵심 기술로 포털은 자신의 서비스를 공개한다. 하지만 기존의 웹서비스와 openAPI 검색은 효율적인 검색 방법을 제공하지 않았다. 본 논문에서는 Lee[1]의 논문에서 제공하는 효율적인 웹서비스 검색 방법을 이용하여 검색 엔진을 개발하였다. 하지만 이 연구는 웹서비스와 유사한 구조를 가지는 openAPI를 수용하지 못한다. 따라서 본 논문에서는 openAPI의 정의 및 사용법이 웹서비스와 유사하다는 점을 활용하여 openAPI의 효과적인 검색을 위한 검색기법을 개발하였다. 이러한 검색기법은 사용자가 키워드를 입력하여 키워드 기반 검색을 통해 원하는 서비스를 찾아주고, 매쉬업 서비스나 다른 openAPI와의 조합(Composition)을 위해 템플릿 기반 검색을 통해 효과적인 검색을 제공해준다.

  • As the compact and easily accessible handheld devices, such as cellular phones and MP3 players equipped with image acquisition functionality, are becoming widely available among common users, various applications of images are rapidly increasing. Image related services and software such as web-based image presentation and image manipulation for personal or commercial purpose enable users to view contents of remote image archive and to manipulate enormous amount of images in local or network based storage as well. It is necessary for users to identify the images efficiently so that the same images are perceived as one physical entity instead of recognizing them as different images as the trends are getting stronger. In order to support this environment, we propose a method that generates image identifiers or indexing for images within a solid and efficient manner. The proposed image identifier utilizes multiple index values. The integration of component index values creates a unique composite value that can be used as a file name, file system identifier, or database index. Our experimental results on generation of constituent index values have shown favorable results.

  • It is important to consider interaction between species in understanding structure and function of the biological community. Current ecological issues such as climate change and habitat loss emphasize the significance of the concept of species interaction in that varying species' interaction across environmental gradients may lead to altered ecological function and services. However, most community studies have focused on species diversity through analysis of quantitative indices based on species composition and abundance data without considering species interactions in the community. 'Ecological network analysis' based on network theory enables exploration of structural and functional properties of ecosystems composed of various species and their interactions. In this paper, network analysis of Cheonggye stream as a case study was presented to promote uses of network analysis on ecological studies in Korea. Cheonggye stream has a simple biological structure with link density of 1.48, connectance 0.07, generality 4.43, and vulnerability 1.94. The ecological network analysis can be used to provide ecological interpretations of domestic long-term monitoring data and can contribute to conserving and managing species diversity in ecosystems.

  • Purpose: The purpose of this study is to develop a realistic illustration using watercolors on a complete airway obstruction maneuver that is at an appropriate level for elementary school students from the first grade through the third. The illustration is a series of cuts divided into specific frames designed to illustrate the method to be followed in an action or a practical skill that would otherwise be too difficult to explain in written form. Methods: The fundamental theory of the Jeong In-Sung's instruction learning program based on the WEB to construct an appropriate site of instruction learning was used after modification. In this study analysis, design, and production stages were realized. Results: 1. In Stage 1, impressions of the illustration, in sketch form, were received. In Stage 2, results of impressions from a modified illustration were received. After an appropriate level of understanding and accuracy in the practical steps for emergency maneuvers were achieved the illustrations entering Stage 3 and color was added to the sketches. 2. In Stage 3, the illustration was completed by adding color to the contents for the practical steps in the complete airway obstruction maneuver. 3. For composition evaluation, a result of 100% appropriateness was obtained for both items of harmony between illustration and subject being studied and sufficiency in quantity of illustrations. Also high results for appropriateness in items such as clarity, creating interest, illustration size, and tone preference as related to content were achieved and thus completed the production stages. Conclusion: The Complete Airway Obstruction Maneuver Illustration developed specifically for the characteristics and cognitive level of elementary school students grade 1 through grade 3 was appropriate for teaching and learning. There is a need for future research on developed illustrations aimed at elementary school students grade 1 through 3 on the complete airway obstruction maneuver. There is also a need for continued effort in developing certified evaluating tools that can judge the suitability of illustrations and developing illustrations related to emergency maneuvers for various subjects and appropriate for learner level.

  • As a result of trying the various manufacturing methods considering the reality of manpower and equipments with this manual, the following standardized procedures and contents can be suggested. (1) Since tools presenting Rock-Drill data must formalize the order of explanation although explainers are different, it will be valid that it is configured by existing power point method rather than by web document type. Composition of contents are selected on the basis of defence card and survey and then 8 items including initial screen, peripheral conditions, mobilization route, general conditions, use and structure by floor, department of vehicle consideration in activities and end screen are included. (2) Making methods and cautions of data included and used in power point are as follows ; - It was most effective that objects of fire fighting and location of neighboring fire fighting water were expressed by electronic map and drawing of inner building was made by scanning it after paining general architecture drawing(plan by each floor) rather than using drawing tools of EXCEL program or CAD drawing. And it was helpful to simplify contents of architecture drawing to wall, stairs and gate in understanding them. - Photographing of video data should be taken to show available fire fighting facilities in fire, use of planned space and the whole inner structure of each floor from the inside of fire fighting buildings and to display play time between 10 sec. and 1 min, for obstacles to distance from adjacent buildings or passage of special vehicles and fire fighting water from the outside of the building. - File format of video data taken in this way is most suitable to use wmv(window media video) or asf(advanced streaming format) type in consideration of time required for export, screen quality, file capacity and play type in Rock-Drill through network. - Still screen(photo) is more effective to express the department of fire fighting vehicles or other equipments than using video. (3) In configuration work of power point, hyper link was used most and configured to see any part at any situation like web document and then uniformity of presentation order of power point was complemented. (4) In case of sales facilities with the area of $35.557m^2$, the time of 22 hours and 30 minutes for five days was taken with five persons. Therefore, when eight-hour works a day were calculated, the whole process of video work for Rock-Drill can be finished with three day works.

  • 클라우드 컴퓨팅은 컴퓨팅 자원에 대해 확장 가능한 요구중심의 서비스를 인터넷상에서 제공하는 인터넷 기반의 컴퓨팅이라 할 수 있다. 이러한 환경에서 서비스 사용자가 만족하는 서비스를 선정하여 제공하는 문제는 인터넷과 모바일 기술의 발전에 따라 향후에 다양하고 수많은 클라우드 서비스가 제공되는 경우 매우 중요한 이슈중의 하나가 된다. 과거 연구의 대부분은 요구사항과 연관된 개념의 유사성을 기반으로 하거나 사용자 요구사항의 다양성이 결여되어 있어 사용자의 만족도 향상에 한계를 보이고 있다. 본 논문에서 제안하는 방안은 서비스 만족도 향상을 위해 속성의 개념 유사성 대신에 서비스 속성의 기능적 포함 관계와 규격 등을 기반으로 구성되는 서비스 속성 그래프(Service Attribute Graph : SAG)를 도입하여 사용한다. 뿐만 아니라, 다양한 사용자 선호도를 반영하고 문자, 숫자, 부울린 등 여러 가지 속성 값 유형들을 고려함으로서 서비스 속성의 다양성을 지원한다. 본 논문의 가장 큰 의미는 다른 연구들과 달리 여러 가지 사용자 선호도를 통합적으로 고려하면서 그래프 기반의 선정 방안을 처음으로 제시하고 있다는 점이다.

  • 웹 2.0 기술의 발전에 따라 사용자가 임의로 서비스 공간을 재구성할 수 있는 개인화 서비스의 수요가 증가하고 있다. 이러닝 분야에서도 점차 개인화 서비스를 적용하여 사용자에게 학습 공간의 재구성을 위한 다양한 기능들이 제공되고 있다. 그러나 기존의 개인화 서비스인 컴포넌트 단위의 레이아웃 재배치는 학습자에게 제한된 요소의 변경만을 허용하기 때문에 세부적인 구성 변경이 이루어질 수 없다. 또한 이러한 재배치 정보를 다른 용도로 활용하지 못하고 있다. 본 논문에서는 학습 공간의 컨트롤 단위 재구성을 위한 e-Space Manager와 동적 컨트롤 배치 기법을 제안하고 이를 통해 사용자가 배치하는 컨트롤이 콘텐츠의 특성에 최적화되어 구성됨을 확인한다. 제안하는 컨트롤 배치 기법은 사용자가 학습 공간의 구성을 컨트롤 단위로 조정할 수 있다는 장점이 있다. 이는 콘텐츠의 배치뿐만 아니라 시스템 개발자가 허용한 범위 내에서 컨트롤의 변경을 통해 콘텐츠의 입 출력 형태를 학습자가 임의로 구성할 수 있게 된다. 그리고 컨트롤 배치를 통해 생성되는 재구성 정보와 사용 기록을 바탕으로 사용자 선호도에 따른 컴피턴시 모델에 사용될 수 있는 자료를 생성한다.
