Google에서는 GWT라는 웹2.0시대의 핵심기술인 AJAX를 기반으로 한 개발 툴킷을 발표했다. GWT는 Desktop Application 수준의 웹 시스템을 Java로 구현하여 AJAX Application을 재사용 가능하도록 한다. 이에 따른 비동기 통신 방식에서의 모델(M)과 콘트롤러(C)가 RPC 서비스에 적용되는 방법이 기존의 Java 웹 프레임워크에서 적용한 페이지 단위의 방식인 동기식 통신이 적용되는지 분석하고 비동기 통신 방식에 간단한 디자인패턴을 사용하여 구현 하였을 때 효율성이 기존의 프레임워크보다 높은가를 평가한다.

This study was covered with the analysis of five kinds of the middle school science text books(chemistry part) based on the oth curriculum. Particularly, inquiry activities part was analyzed by the three dimension framework which consists of inquiry content dimension, inquiry process dimension and inquiry context dimension and the results are as follows;1. In the analysis of the contents in the middle school science textbooks(chemistry part), the average number of total pages was 197.6. The illustration and picture were contained 0.66 in number per a page, and the average number of further readings was 5.8.2. In the analysis of the inquiry content dimension of inquiry activities, the total number of themes in five kinds of textbooks was 222. And the number of imquiry activities in five kinds of textbooks was siverse : A textbook had 51, B texbook 49, C textbook 37 and E textbook 35.3. For the analysis of inquiry process dimension. it follows in the order of 'interpreing data and formulating generalizations (42.4%)','observation and measuring (38.1%)','seeing a problem and seeking ways to solve it (7.8%)' and 'building, testing and revising the theoretical model(11.7%)'.4. As for the analysis of the inquiry context dimension, the scientific context occupied 94.2%, the individual context 0.4%, the social context 2.7% and the technical context 2.7%. It shows that the proportion of STS(Science-Technology-Society) related contents in inquiry activities was only 5.8%.

As a mathematical technique with which we can find the minimum duration time needed to fire all the transitions at least once and coming back to the initial marking in a timed net, the minimum cycle time method has been widely used in computer system analysis. A timed net is a modified version of a Petri net where a transition is associated with a delay time. A delay time used in a timed net is a constant even though the duration time associated with an event in the world is a stochastic number in general. In the consequence, the result of minimum cycle time analysis is not realistic. Therefore, we propose ‘Stochastic Timed Net' where a transition can be associated with a stochastic number and introduce a minimum cycle time analysis method for ‘Stochastic Timed Net’ As an example of the application of ‘Stochastic Timed Net’, we introduce a ‘Stochastic Timed Net' model of a Location Based Service Providing Multimedia System and the result of minimum cycle time analysis of it. Whereas the typical form of the result of the existing minimum cycle time analysis is 'It takes at least 10 time units', the typical form of the result of minimum cycle time analysis of a ‘Stochastic Timed Net' is in the probability form such as "The probability of the events in which it finishes its job within 10 time units is 85%."

기존의 웹 컨텐츠는 유선망에 접속된 PC를 대상으로 제작되었기 때문에 무선환경의 단말기 상의 소형 디스플레이에서 표현되기 위해서는 웹 문서의 변환이 필요하다 이를 위해 본 논문에서는 웹 컨텐츠를 자동 변환하는데 있어서 필요한 인덱스를 추출하는 기능을 제공한다. 기존의 방법과는 달리 HTML 태그 패턴 분석뿐만 아니라 컨텐츠 정보의 속성 분석을 통하여 실시간 분석으로 웹 문서 변환에 필요한 인덱스 정보를 추출하는 방식을 제안한다. 웹 페이지에서 인덱스 정보를 추출하고 이러한 인덱스 정보를 브라우저에게 전달함으로써, 웹 문서 변환에 있어서 콘텍스트를 제공하고 변환의 유연성을 향상시킬 수 있다.

전체 웹 트래픽 요소 중 가장 큰 비중을 차지하는 HTTP 트래픽을 대상으로 하여 과거의 데이터와 비교 분석해 보았다. 현재의 웹 페이지의 경우 최소 10개~ 20개 이상의 또 다른 객체를 요청 하게 되고 있음을 발견했다. 이는 텍스트가 주를 이루었던 과거의 객체들과 매우 다른 양상을 보인다. 최근의 웹 트레이스 로그를 분석하여 기존 알고리즘들의 문제점을 발견하여 지적 하며 새로운 캐싱 알고리즘의 개념을 제안한다.

The "About Us" page on the website of a corporation provides information regarding the organization's vision, philosophy, and values. We examine the association between institutional information provided on corporate websites (i.e., the "About Us" section) with present and future financial performance. Utilizing a text mining technique, we analyze the institutional information of S&P500 firms in the year 2016. We conduct a factor analysis including words that are intentionally repeated in the introductory text of corporate websites. The results of the analysis reveal that keywords from this institutional information can be grouped into six factors. We then carry out an ordinary least squares regression analysis to determine the associations between these six factors and present financial performance. The results show that keywords in Factor 2 (those related to Purchasing experience) are positively associated with ROE, a variable representing present financial performance, while keywords in Factor 1 (those related to Note to customers) show a negative relationship with ROE. On the other hand, keywords in Factor 1 have a positive relationship with Tobin's Q, a variable representing future financial performance. These results indicate that there is some relationship between the words used in the institutional information in this section of corporate websites and firms' financial performance. Hence, the institutional information on a website may be a useful indicator of current firm performance and future firm value.

This study identifies the characteristics of recent citation-based indicators for assessing a single paper in the context of their co-relationships. Five predefined indicators were examined with three variants of h-index which are convened in this study; the formers are PageRank, SCEAS Rank, CCI, f-value, and single paper h-index and the latters are $h_S$-index, h1-index, and $h_S$1-index. The correlation analysis and cluster analysis were performed to group the indicators by common characteristics, after which the indicators were calculated with the dataset from KSCI DB. The results show statistical evidence that distinguishes h-index type indicators from others. The characteristics of the indicators were verified with citation frequency factors using correlation analysis. Finally, the implications for applications and further studies are discussed.

This study analyzed NCS-enabled Web services at colleges. The search scope was based on the NCS Support Center, etc. of the two domestic and one overseas portal sites. Support for the NCS Support Center web service from 12 Junior Colleges was analyzed after the search. There were three categories of NCS-enabled Web services. First, NCS-enabled service status analysis, second, NCS-enabled project status analysis, and third, junior college-specific differentiated NCS-enabled web service analysis were conducted. As a result, NCS-enabled services had more quantitative web pages than NCS-enabled project status services. However, NCS-enabled project status services have been presented with more detailed and practical data than NCS-enabled services. Differentiated Web services were able to analyze what included efforts to maximize NCS Web service support for each Junior College. Based on the results of this study, we look forward to improving the quality of NCS-enabled web services for Junior College education.
