The conversion of the international standard web utilization HTML5 technology is being developed for improvement of the internet environment based on nonstandard technology like ActiveX. Hyper Text Markup Language 5 (HTML5) of basic programming language for creating a web page is designed to consider the security more than HTML4. However, the range of attacks increased and a variety of security threats generated from HTML4 environment inherited by new HTML5 API. In this paper, we focus on the script-based attack such as CSRF (Cross-Site Request Forgery), Cookie Sniffing, and HTML5 API such as CORS (Cross-Origin Resource Sharing), Geolocation API related with the infringement of the personal information. We reproduced the infringement cases actually and embodied a detection module of a Plug-in type diagnosed based on client. The scanner allows it to detect and respond to the vulnerability of HTML5 previously, thereby self-diagnosing the reliability of HTML5-based web applications or web pages. In a case of a new vulnerability, it also easy to enlarge by adding another detection module.

This paper analyzes user preferences on the basic structure of digital textbook contents based on the PDF and HTML formats. This was conducted by analysing the data from an online survey on user preferences for the representative structures of the PDF- and HTML-based digital textbook contents that are currently used on the Web. Results show that in the PDF format, the structure with TOC(Table Of Contents) links on the left screen and the main content on the right was most preferred by 82% of the respondents. In terms of the viewing method, the one that presents one page of the textbook fitted to the width of the computer screen in a single-page view was regarded as the best. Similarly, in the HTML format, the structure with TOC links on the left frame and the main content on the right using 2-frames was revealed as the most preferred by 84% of the respondents. However, the structures of the PDF- and HTML-based digital textbook contents employed by most existing Web sites go against the users' preferences. Accordingly, for digital textbook development in the future, user preferences must be considered to allow students to read the contents more easily and conveniently.

A few years ago, many people proposed that a plaza be added to Seoul City Hall. The proposal, however, did not materialize because of traffic confusion. The June 2002 World Cup cheering in front of Seoul City Hall has prodded the public to reconsider the plaza. Even though the exercise failed to gain support, many democratic procedures, opening a Web page and design competitions, and so on were attempted while the design and management of Seoul City Hall Plaza was being deliberated. In the future, the need for proper communication and democratic procedures in the process of making decisions regarding public spaces is expected to increase because of the strengthening of the requirement of participatory and deliberative democracy. An examination of the nature and extent of the communication that has been carried out in relation to the plan to add a plaza to Seoul City Hall will be very helpful in gathering feedback to guide decision-making in regards to the use of other public spaces. Thus, this study has a three-fold purpose. : (1) to examine the theories that may justify the need for public input in relation to decisions made regarding the use of public spaces, and to propose the criteria to be used for the methods of communication (2) to examine the contents and conflicts of communication in relation to the decision made regarding the design and management of Seoul City Hall Plaza and (3) to examine the potential distortion of that communication by analyzing the communication according to the criteria previously proposed. The study method that is used herein is the analysis of articles about the subject matter, which have been posted on the Seoul City Hall Plaza Website and which have been published in newspapers such as the Chosun ilbo, Donga ilbo, the Jungang ilbo, and the Hankyoreh. Diverse article contents are also discussed. As result, there are many differences in the contents and viewpoints of the newspapers that are included in this study. In addition, the related Internet bulletin board has not been used actively, but has contributed to forming public opinion on this issue. Finally, the public demanded to be given acceptable reasons for the results of the design competition, and for the decision to make the grass plaza, which ignores the chosen design in the newspapers or on the Web page. However, their demand was rejected. The communication therefore became distorted and consequently did not become successful in bringing about its intended result.

월드 와이드 웹(World Wide Web)에 존재하는 음란성 유해 정보는 많은 국가에서 사회적인 문제를 일으키고 있다. 그러나 현재 음란성 유해 정보로부터 미성년자를 보호하는 실효성 있는 방법은 유해 정보 접근 차단 프로그램을 사용하는 방법뿐이다. 유해 정보 접근 차단 프로그램은 기본적으로 음란성 유해 정보를 포함한 유해 정보 주소 목록을 기반으로 사용자의 유해 정보에 대한 접근을 차단하는 방식으로 동작한다.그런데 대규모 유해 정보 주소 목록의 확보를 위해서는 월드 와이드 웹으로부터 음란성 유해 정보를 자동 색출하는 인터넷 정보 검색 시스템의 일종인 음란성 유해 정보 색출 시스템이 필요하다. 그런데 음란성 유해 정보 색출 시스템은 그 대상이 사람이 아닌 유해 정보 접근 차단 프로그램이기 때문에 일반 인터넷 정보 검색 시스템과는 달리, 대단히 높은 검색 정확성을 유지해야 하고, 유해 정보 접근 차단 프로그램에서 관리가 용이한 검색 목록을 생성해야 하는 요구 사항을 가진다.본 논문에서는 기존 인터넷 정보 검색 모델이 "문헌"에 대한 잘못된 가정 때문에 위 요구사항을 만족시키지 못하고 있음을 지적하고, 월드 와이드 웹 상의 문헌에 대한 새로운 정의와 이를 기반으로 위의 요구사항을 만족하는 검색 모델인 페이지 그룹 검색 모델을 제안한다. 또한 다양한 실험과 분석을 통해 제안하는 모델이 기존 인터넷 정보 검색 모델보다 높은 정확성과 빠른 검색 속도, 그리고 유해 정보 접근 차단 프로그램에서의 관리가 용이한 검색 목록을 생성함을 보인다.Abstract Illegal and Harmful Content on the Internet, especially content for adults causes a social problem in many countries. To protect children from harmful content, A filtering software, which blocks user's access to harmful content based on a blocking list, and harmful content search system, which is a special purpose internet search system to generate the blocking list, are necessary. We found that current internet search models do not satisfy the requirements of the harmful content search system: high accuracy in document analysis, fast search time, and low overhead in the filtering software.In this paper we point out these problems are caused by a mistake in a document definition of the current internet models and propose a new internet search model, Page Group Search Model. This model considers a document as a set of pages that are made for one subject. We suggest a Group Construction algorithm and a Group Evaluation algorithm. And we perform experiments to prove that Page Group Search Model satisfies the requirements.uirements.

This study empirically examines the differences in attitude and memory effect according to the product knowledge (high knowledge / low knowledge) and temporal distance (near future / far future) in the new product preannouncing strategy of companies through Facebook Respectively. Experiments were conducted by inserting the experiment into a virtual web browser using Facebook 's actual brand fan page and then connecting the experiment to the experimental banner site. As a result of research, when preannouncing new products are released in the near future, low knowledge consumers have made judgments of purchasing decisions because GRM judgments are more favorable than property information (ARM) judgments, but preannouncing is a new product At the time of launch, highly-knowledgeable consumers had a positive effect on the property information (ARM) judgment of the product rather than the comprehensive information (GRM) judgment. In addition, when preannouncing was introduced in the near future, the attitudes of the products between the low-knowledge consumers and the high-knowledge consumers were all positive, but when the new products were launched in the distant future, Product attitude was negative.

Most Web search engines use ranking methods that take both the relevancy and the importance of documents into consideration. The importance of a document denotes the degree of usefulness of the document to general users. One of the most successful methods for estimating the importance of a document has been Page-Rank algorithm which uses the hyperlink structure of the Web for the estimation. In this paper, we propose a new importance estimation algorithm for the blog environment. The proposed method, first, calculates the importance of each document using user's bookmark and click count. Then, the Guru point of a blogger is computed as the sum of all importance points of documents which he/she wrote. Finally, the guru points are reflected in document ranking again. Our experiments show that the proposed method has higher correlation coefficient than the traditional methods with respect to correct answers.

In this paper, we propose an Raspberry Pi2-based smart home security monitoring system. Proposed home security monitoring system was configured using a relatively tractable main processor raspberry pi2, ultrasonic sensors, and PIR sensors. In addition, The picamera is compatible with raspberry pi2 was connected to the servo motor. And by driving the attacker's location the video was recording. The Web server stores data of the recorded image and the sensor, and provides a web page to enable the monitoring at all remote locations. When examining efficiency of proposed home security monitoring system it was found that proposed system is easier to be made than existing home security system and is able to minimize the blind spot of the camera by using servo motor and is efficient and convenient and stable as it enables a user to handle an error in person and it uses reliable data.
