A study of the members of the editorial boards of 16 leading LIS journals shows that the boards vary markedly in size, in diversity (in terms of both gender and nationality) and in the experience and publication/citation profiles (based on Web of Science data) of their board-members. A typical editorial board member will be male, work in the USA, have published their first LIS article in 1995, and have 9.5 publications and 39 non-self citations to those publications, with the publication/citation profiles differing significantly from those of non-board-member contributors to the 16 journals.

In this paper, we will present the realization of a facial recognition system using the ESP32-CAM board controlled by an Arduino board. The goal is to monitor a remote location in real time via a camera that is integrated into the ESP32 IOT board. The acquired images will be recorded on a memory card and at the same time transmitted to a pc (a web server). The development of this remote monitoring system is to create an alternative between security, reception, and transmission of information to act accordingly. The simulation results of our proposed application of the facial recognition domain are very efficient and satisfying in real time.

An embedded system has been applied to many fields including households and industrial sites. In the past, user interface products with simple functions were commercialized .but now user demands are increasing and the system has more various applicable fields due to a high penetration rate of the Internet. Therefore, the demand for embedded system is tend to rise In this paper, we Implementation of an embedded system for image tracking. This system is used a fixed IP for the reliable server operation on TCP/IP networks. A real time broadcasting of video image on the internet was developed by using an USB camera on the embedded Linux system. The digital camera is connected at the USB host port of the embedded board. all input images from the video camera is continuously stored as a compressed JPEG file in a directory at the Linux web-server. And each frame image data from web camera is compared for measurement of displacement Vector. That used Block matching algorithm and edge detection algorithm for past speed. And the displacement vector is used at pan/tilt motor control through RS232 serial cable. The embedded board utilized the S3C2410 MPU Which used the ARM 920T core form Samsung. The operating system was ported to embedded Linux kernel and mounted of root file system. And the stored images are sent to the client PC through the web browser. It used the network function of Linux and it developed a program with protocol of the TCP/IP.

The purpose of this study is to investigate the effects of types of social media on academic achievement, interaction, and social efficacy in web-based project learning. To accomplish the purpose of the study, an experiment was conducted with 78 six graders who attend S elementary school in I metropolitan city. They were assigned to 'Facebook' group, 'Wiki' group, and web bulletin board group. The academic achievement score of Wiki group was higher than that of web bulletin board group. There was significant difference between task-oriented interaction and relation-oriented interaction in Wiki group. In addition, relation-oriented interaction was more active than task-oriented interaction in Facebook group. Finally, social efficacy score of Facebook group was higher than that of Wiki group.

For the better success in the society, it is important to collect opinions from members. The progress was slow before because it was hard to collect the opinions from each member. But since we have opened the web site it gets easier to evolve with the society for microsurgery, and expect to have active participations from the members. We make 20 questions in three different groups. The researches are made on participation, development in science council that starting from 2005 October to 2007 June, education on training with member's preference to thesis and individuality and suggestion. Thus we have results following to that research. 1.75% of the members vote for the lecture has to be substantial, and also want the atmosphere of the council to be more sincere. 46.2% of members want the council to be not only exchange information but also the place to experience the social intercourse. 2. When the thesis is present and submitted that will also connect to main society. It will be counted as equal as board thesis, only if the thesis can count in both plastic & reconstructive surgery and orthopedic surgery. Then it will be scored as same as examination of board, and will be a receipt of paper by home page 3. The information-oriented project on our council is slower than what members expected. 100% of members voted yes to online thesis examination, and 66.7% of members voted for preference of web site. We need to make improvements on our web pages as soon as possible such as online payment with credit card. 4. According to the result of questionnaire, our web site helps member's participation in council and eventually become a bridge between members. We hope the questionnaires would help us to develop the council and eventually would help us to society with each other in the council. We also hope this council would be the one that connect all of us in society.

Hearing-impaired people have difficulty in hearing, so it is also hard for them to learn letters that represent sound and text that conveys complex and abstract concepts. Therefore it has been natural choice for the hearing-impaired people to use sign language for communication, which employes facial expression, and hands and body motion. However, the major communication methods in daily life are text and speech, which are big obstacles for the hearing-impaired people to access information, to learn and make intellectual activities, and to get jobs. As delivering information via internet become common the hearing-impaired people are experiencing more difficulty in accessing information since internet represents information mostly in text forms. This intensifies unbalance of information accessibility. This paper reports web-based text-to-sign language translating system that helps web designer to use sign language in web page design. Since the system is web-based, if web designers are equipped with common computing environment for internet browsing, they can use the system. The web-based text-to-sign language system takes the format of bulletin board as user interface. When web designers write paragraphs and post them through the bulletin board to the translating server, the server translates the incoming text to sign language, animates with 3D avatar and records the animation in a MP4 file. The file addresses are fetched by the bulletin board and it enables web designers embed the translated sign language file into their web pages by using HTML5 or Javascript. Also we analyzed text used by web pages of public services, then figured out new words to the translating system, and added to improve translation. This addition is expected to encourage wide and easy acceptance of web pages for hearing-impaired people to public services.

Web designers generally use a story board, a site map, a flow chart or the combination of these for representing web sites. But these methods are difficult to represent the entire architecture of a web site, and may be not adaptive for describing the detail flow of web pages. To solve these problems to some degree, there were works using EMFG(Extended Mark Flow Graph) recently. However the conventional EMFG representation method is not adaptive to represent the dynamic interface of web sites because that cover only the static parts of a web site. Internet utilization is rapidly growing in our life and we cannot imagine the worlds of work, study and business without internet. And web sites recently have not only more complex and various architecture but also web pages containing the dynamic interface. Therefore we propose the representation method of these web sites - for example, a web site containing varying pages with time and varying page status or contents with mouse operations - using EMFG. We expect our work to be help the design and maintenance of web sites.
