As we transition into an artificial intelligence-driven society, data collection and utilization are actively progressing. Consequently, currently there are emerging technologies and privacy models to convert original data into anonymized data, while ensuring it does not violate privacy guidelines. Notably, privacy models including k-anonymity, l-diversity, and t-closeness are actively being used. Depending on the purpose of the data, the situation, and the degree of privacy, it's crucial to choose the appropriate models and parameters. Ideally, the best scenario would be maximizing data utility while meeting privacy conditions. This process is called Privacy-Preserving Data Publishing (PPDP). To derive this ideal scenario, it is essential to consider both utility and privacy indicators. This paper introduces a new utility indicator, the Effect Size Average Cost, which can assist privacy administrators to efficiently create anonymized data. This indicator pertains to the correlation change between quasi-identifiers and sensitive attributes. In this study, we conducted experiments to compute and compare this indicator with tables where k-anonymity, l-diversity, and t-closeness were applied respectively. The results identified significant differences in the Effect Size Average Costs for each case, indicating the potential of this indicator as a valid basis for determining which privacy model to adopt.

Cyberspace permits us to more beyond traditional face-to-face, mail and telephone surveys, yet still to examine basic issues regarding the quality of data collection: sampling, questionnaire design, survey distribution, means of response, and database creation. This article address each of these issues by contrasting and comparing traditional survey methods(Paper-and-Pencil) with Internet or Personal Computer networks-mediated (Screen-and-Keyboard) survey methods also introduces researchers to this revolutionary and innovative tool and outlines a variety of practical methods for using the Internet or Personal Computer Networks. The revolution in telecommunications technology has fostered the rapid growth of the Internet all over the world. The Internet is a massive global network and comprising many national and international networks of interconnected computers. The Internet or Personal Computer Networks could be the comprehensive interactive tool that will facilitate the development of the skills. The Internet or Personal Computer Networks provides a virtual frontier to expand our access to information and to increase our knowledge and understanding of public opinion, political behavior, social trends and lifestyles through survey research. Comparable to other technological advancements, the Internet or Personal Computer Networks presents opportunities that will impact significantly on the process and quality of survey research now and in the twenty-first century. There are trade-offs between traditional and the Internet or Personal Computer Networks survey. The Internet or Personal Computer Networks is an important channel for obtaining information for target participants. The cost savings in time, efforts, and material were substantial. The use of the Internet or Personal Computer Networks survey tool will increase the quality of research environment. There are several limitations to the Internet or Personal Computer Network survey approach. It requires the researcher to be familiar with Internet navigation and E-mail, it is essential for this process. The use of Listserv and Newsgroup result in a biased sample of the population of corporate trainers. However, it is this group that participates in technology and is in the fore front of shaping the new organizations of interest, and therefore it consists of appropriate participants. If this survey method becomes popular and is too frequently used, potential respondents may become as annoyed with E-mail as the sometimes are with mail survey and junk mail. Being a member of the Listserv of Newsgroup may moderate that reaction. There is a need to determine efficient, effective ways for the researcher to strip identifiers from E-mail, so that respondents remain anonymous, while simultaneously blocking a respondent from responding to a particular survey instrument more than once. The optimum process would be on that is initiated by the researcher : simple, fast and inexpensive to administer and has credibility with respondents. This would protect the legitimacy of the sample and anonymity. Creating attractive Internet or Personal Computer Networks survey formats that build on the strengths of standardized structures but also capitalize on the dynamic and interactive capability of the medium. Without such innovations in survey design, it is difficult to imagine why potential survey respondents would use their time to answer questions. More must be done to create diverse and exciting ways of building an credibility between respondents and researchers on the Internet or Personal Computer Networks. We believe that the future of much exciting research is based in the Electronic survey research. The ability to communicate across distance, time, and national boundaries offers great possibilities for studying the ways in which technology and technological discourse are shaped. used, and disseminated ; the many recent doctoral dissertations that treat some aspect of electronic survey res

This paper discusses management education by utilizing the cyber education learning system in a web-based. New learning system tools offer great promise for a new contents of management learning. The cyber education learning system a shift from face-to-face lecturing to interactive learning. The situation changes profoundly when information technology becomes develope and education paradigm is shift. By exploiting the digital media. educations, and students, managers can shift to a new, more effect cyber education learning system. The following shift from classic educations to cyber educations learning system: from instruction to construction, from teacher-centered to learner-centered, from school to lifelong, from one-size-fits-all to customized, from teacher as transmitter to teacher as facilitator. Cyber education learning system has an important role to play in management education. Web-based technology is regarded as a general solution to cyber education learning. This study discussed many factors of implementation in cyber education systems and provide utilizing the learning system at main, detail functions. Lastly, management implications of these cyber education utilize are discussed in more detail.

도시철도라 함은 도시교통의 원활한 소통을 위하여 도시교통권역에서 건설·운영하는 철도ㆍ모노레일 등 궤도에 의한 교통시설 및 교통수단을 말한다. 지금까지 차량성능시험은 제작사와 운영체가 자체적으로 시행해 왔으나 신조 제작차량의 잦은 고장과 사고발생으로 인하여 교통불편을 초래하고 있어, 국가에서는 국민의 생명보호와 안전사고예방을 위하여 제도적으로 차량이 영업운행 전에 성능시험을 거치도록 한 것이다. 이에 도시철도차량성능시험에 대해서 간략히 설명하며, 관련 규정을 소개한다.(중략)
