Recently, it is increasing the interest in previous web and web 2.0 which mean differentiation. The previous system is typical Static web based on client and server model, while web 2.0 mean next generation web which web change and evolve fundamentally. In this paper, I suggest that the module on RSS reader available under web 2.0 standards. A currently used RSS feed do correct the part distortion which ran be possible resolve the encoding problem of Hanguel and third-world language. The suggested module is implemented using Ajax. I developed the module for the use of effective contents on web 2.0 through the DragBox module based on the programming on mobility of Ajax and the design and implementation of automatic update module of RSS feed.

WebGL is a cross-platform web standard for a low-level 3D graphics API based on OpenGL ES 2.0 and presents 3D graphics in web browsers without installing extra plug-ins. The reason that WebGL is notable is because it is included in the HTML5 standard which is getting the spotlight as a next-generation RIA(Rich Internet Application) platform for variable devices such as PCs, smart phones, table PCs, and smart TVs. In this research, we would like to introduce and develop a behavior engine for easy and rapid authoring of complicated interactions and 3D object's behavior models in WebGL-based contents.

More and more employees are implementing the use of emerging Web 2.0 tools such as blogs, wikis, social networks, etc in workplaces. However, their attitudes towards adoption of Web 2.0 tools in workplaces still lack theoretical support. The purpose of this study aims to provide a conceptual examination of the determinants that influence the intention to use Web 2.0 applications in workplaces in Korea. To achieve this objective, this study selected the theory of reasoned action (TRA) as a theoretical basis to explain variation in behavioral intentions. Structural equation modeling was employed to analyze data collected from 269 workers distributed in 5 companies in Korea. In addition, we classified respondents into extroverts and introverts and delineated the different factors for these two types of respondents that affect their intentions to use Web 2.0 tools in workplaces. The findings of this research could provide a theoretical foundation for academics on the validation of technology adoption. This research will also serve as a guideline for service providers in designing the Web 2.0 services.

Web 3.0 is also called the "next-generation Internet" and is a new concept that started in 2018 and is attracting attention as the beginning of the "distributed Internet era". As Web 3.0 became mainstream, non-fungible tokens (NFTs) serving as content as services were distributed, and companies started to introduce NFTs in their marketing campaigns. This is because NFTs can be used to promote brands to new consumers. In this study, using Japan's 「HARTi」 NFT Art as an example, we investigate a new method using urban infrastructure and spaces, not NFTs that exist only in the Japanese art market and online. By analyzing social issues following the introduction of a new digital marketing method based on NFT Art, we will discuss issues and countermeasures in the domestic NFT Art market and present a positive outlook.

The catalytic combustion of particulate matter (PM) is one of the key technologies to meet emission standards of diesel engine system. Therefore, we herein suggest Ag loaded $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_3$ perovskite web catalyst. They were produced by the electrospinning method. FE-SEM, EDS mapping, XRD, XPS were studied to investigate the crystal and morphological structures of loaded Ag particles and $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_3$ perovskite web catalyst. Following the catalytic soot oxidation, we found that the Ag loaded $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_3$ perovskiteweb catalyst showed the higher catalytic activities (e.g., $T_{50}=490^{\circ}C$) than the only $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_3$ perovskite web catalyst (e.g., $T_{50}=586^{\circ}C$). Thus, this finding suggests that Ag loaded $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_3$ perovskite web catalyst can be a promising candidate for enhancing the soot oxidation.

The environment of web service has changed a great deal due to the progress of internet technology and positive participation of users. The established web service is static and passive, but the recent web service is becoming dynamic and active. Web 2.0 reflects current web service change well. The primary feature of web 2.0 is positive participation of users. Since the size of generated information is becoming larger, it is highly required to share the information fast and correctly. The technology to satisfy this need is web syndication and tagging in web 2.0. The web syndication makes feeds for another site or users to receive the content of web site. In addition, the tagging is the kernel of a information. Many internet users share rapidly the information through tag search. In this paper, we propose the efficient technique to improve the web 2.0 technology such as web syndication and tagging by using the data collection engine. Data collection engine has stored in a database, a user's Web site to use the information. and it has a user's Web site with access to updated data to collect. The experimental results show that our approach can improve the search speed up to 3.14 times better than the existing method and reduce the size of data up to 66% for building associated tags.

The early web technology was 2D type and exchange of information was passive generally. AS the time had passed, users wanted to participate in the 3D environment which is similar to real world actively. However VRML which is expected to bring big changes of the web environment has not been expanded owing to various circumstances. At a recent Web 2.0 is the most popular topic in the Internet business. Basic concept of Web 2.0 is implementation of comfortable UI(User Interface) and implementation of more active web than previous web. Concept of RIA(Rich Internet Application) is one of the Web 2.0 important technologies. In this paper, we designed and implemented Web Environmental Sensor Data System which has fantastic UI and various functions by using Flex.

In this study, twelve strains of brewing fungi were individually cultivated on wheat extract broth (WEB), potato dextrose broth (PDB) and malt extract broth (MEB) in order to determine the microorganism with good culture characteristics as well as with amylolytic activity. The strain cultured in PDB exhibited mycelia production from 12.6 g/L (Rhizopus oryzae KACC 45714) to a maximum of 48.0 g/L (Aspergillus oryzae KACC 46959), which was 2.3~9.2 times lower than that of the strain cultured in WEB and 1.7~14.6 times lower than that of the strain cultured in MEB. Accorfing the results, We found that the commercial strains of A. oryzae Suwon, CF1001 and CF1003 had a higher dry cell mass than the wild-type strains KACC 46421, 46423, 46424 and 46959. For Rhizopus sp., the acidity levels in WEB, PDB and MEB were 0.12~0.47%, 0.22~1.0% and 0.16~0.68% (equivalent lactic acid concentration) respectively. For A. oryzae, the acidity levels were 0.06~0.11%, 0.03~0.04% and 0.06~0.08% (equivalent lactic acid concentration), respectively. Amylase enzyme from Rhizopus delemar KACC 46419 exhibited an enzyme activity of 0.013 U and 0.019 U in WEB and MEB cultures, respectively. The enzyme activity of the amylase enzyme from A. oryzae was 0.019~0.037, 0.017~0.033 and 0.028~0.046 U in WEB, PDB and MEB cultures, respectively.

This paper evaluates web accessibility using an evaluative measure of K-WAH 3.0. It targets systems and contents in scientific and technological information, based on a guide for 'Internet Web Contents Accessibility 1.0'. The result indicates that web accessibility of informational system is lower than that of informational contents. Based on this fact, this paper identifies the main characteristics and differences of web accessibilities in informational system and contents, and discusses possible improvements. the result of the evaluation found the scientific system sites is more superior than contents sites in web accessibility. And the scientific system and contents sites except NDSL was lest 'understandable' and 'Robust' in observance. Therefore web page that should bring "easily understandable" and "reducing outstanding side effects" was required.
