This paper presents a new architecture, called "Power Electronics Remote Wiring and Measurement Laboratory (PermLAB)", that translates a common gateway interface (CGI) string from a remote web user to a web server connected to a 3-dimension switching matrix board, can be used to switch on and off, and to control a cluster of instruments and components. PermLAB addresses real-time connection, switching, and data acquisition over the Internet instead of using simulated data. A software procedure uses a signature system to identify each instrument and component in a complex system. The Web-server application is developed in HTML, JavaScript and Java, and in C language for the CGI interface, which resides in a controller portion of LabVIEW. The LabVIEW software fully integrates the Web sever, LabVIEW data acquisition boards and controllers, and the 3-dimensional switching matrix board. The paper will analyze a half-wave rectifier (AC - DC converter) circuit connected over the Internet using the PermLAB. PermLAB allows students to obtain real data by real-time wiring of real circuits in the laboratory using a "virtual breadboard" on the Web. The software for the Web-based 3-dimensional system is flexible, portable, can be integrated into many laboratory applications or expanded, and easily accessible worldwide.

Bulletin board systems have evolved to support diverse multimedia data as well as text. However, current board systems have an weakness : it takes much time and efforts for users to figure out contents of articles. Most board systems provide a searching function with lexical level data access for solving that problem, however it fails to serve users' intented searching results. Moreover, it is nearly impossible to search proper articles if they contain multimedia data. This paper proposed a bulletin board system adopting the Semantic Web to solve this issue. The proposed system provides users with new ontology which is used for describing articles' domain knowledge and multimedia features. Users can describe their own board ontology using the proposed ontology. To support semantic-based searching for diverse domain knowledge without modification of the system, the system dynamically generated input/query interface and RDF data access module according to the board ontology written by administrators. The proposed board system shows that semantic-based searching is feasible and effective for users to find their intended articles.

In this paper, an investigation on internet safety of 244 national or public elementary schools' web sites was performed with two points of view : inappropriate material posting and personal information exposure. The investigation results showed that obscene materials and commercial advertisements were uploaded into the bulletin board(67.2%) and students' personal information such as photograph, address, telephone number were exposed(87.3%). Most of the inappropriate materials were posted by auto-register programs. This problem was occurred due to reckless bulletin board opening and inappropriate management. On the contrary, personal information was exposed by teachers and students. They didn't not care about their personal information. It shows the fact that they have not recognized the danger of personal information exposure. Therefore managing real-name membership and enforcing permission to bulletin board were required to construct and use a safe school web site. Teachers have to understand not only negative effects appeared in a school web site but also latent dangerous factors.

Electronic reference service was defined as reference service designed for remote users and identified by a specific link from a library' website. This study examined whether academic libraries deliver web-based electronic reference services to remote users. Particularly, four types of electronic bulletin board services, free bulletin board, FAQ, Q＆A and reference question-response service were measured in terms of 8 types of questions and 12 contents of questions. The result showed that there was few differences among 4 services. Guidelines for effective use of electronic bulletin board services in academic libraries were suggested: standardization of service names, easy access to menu services, definition of each menu, search function for contents and standard web forms.

Purpose - First, this study contextually examines the governance codes of South Africa and South Korea. Second, it analyzes board features of South African (JSE) Mainboard and South Korean (KRX) KOSPI-listed companies. Design/methodology - This review is qualitative and uses data from the annual reports of the selected markets' companies, respective exchanges' official web sites and corporate governance-related web sites in order to examine the corporate governance practices in the two markets. In addition, Nvivo is employed in analyzing the content of the corporate governance codes of the selected countries. Findings - Our analysis indicates that the corporate governance codes of the two countries are evolving to keep up with the international trend of principles-based approach. The composition of the board of directors (BODs) of non-financial companies of both South Africa and South Korea shows no significant variation between the companies with regards to the executive (inside) and nonexecutive (outside) directors. On the contrary, there is a significant variation between South African and South Korean listed companies with respect to diversity. Originality/value - While previous studies are centered on the impact of governance codes on performance, this study intends to contextually evaluate the codes and features of South Africa and South Korea listed companies. This is essential and timely for regulators and policy makers given the importance of corporate governance features such as board independence and diversity in recent times.

Objective In Korea, online board games, such as "flower cards," are played using virtual money. In contrast, Internet-based gambling (ibGambling) concerns the use of real money to gamble online. We hypothesized that online board gamers using virtual money show less risky behaviors than do gamblers who use real money, and that, in regard to psychological aspects, online board gamers are less depressed and more introverted than online gamblers are. Methods For this study, 100 online board gamers, 100 ibGamblers, 100 offline gamblers (offGamblers), and 100 age- and sex-matched healthy controls were recruited by an online research company. Gambling behavior and self-efficacy were assessed using the Korean Gambling Behavior Scale-high/low factors (KGBS-H/L) and the Gambling Abstinence Self-efficacy Scale (GASS). Additionally, introversion, depression, and mania tendency were assessed. Results Online board gamers had good intentions gaming, as evidenced by their higher KGBS-L scores than ibGamblers and offGamblers, and they showed less risky behaviors, as evidenced by their lower KGBS-H scores than offGamblers. Additionally, online board gamers were less introverted than ibGamblers and less depressed than offGamblers. Conclusion Online board gaming could be a gateway to the world of gambling (ibGambling or OffGambling). However, the higher tendency of online board gamers to engage in good intentioned gaming could help prevent online board gaming from progressing to online or offline gambling.
