  • The number of one-person households in the modern society continues to increase, and is expected to increase steadily. In addition, one-person households had the largest number of detached house dwellings, while one-person households had the advantage of free living and free time. However, one-person households have concerns such as loneliness, health problems, safety, risk, and meal solutions, while detached house have problems such as living problems, maintenance, management, safety and risk, and lead to future concerns. This study was conducted in the following ways to improve the concerns of one-person households and the problems of detached house by applying smart home service to detached house. It was integrated through the investigation of concerns and grievances of one-person households and the case of preceding research on the problems of detached house. The latest technology trends of smart home services and the technologies currently developed and marketed were identified through prior research cases and literature surveys. Based on this, the smart home service list and application measures were derived to compensate for the concerns of one-person households and problems of detached house in applying them to smart home services.

  • The Fourth Industrial Revolution era requires people to have the ability of integrated thinking, critics, sensitivity, and creativity in an integrated manner. Therefore, teaching methods are expected to become more suitable for the trend. In this belief, current teacher-leading education method should move to students' self motivating one and consist of programs in which students voluntarily involve. In this reason, this study suggests FPBL educational method model that is combines project-based learning with flipped learning by analysing preceding research and digital painting tool class was designed by applying it. As a result of applying the designed class model to the class, all of the class satisfaction, effectiveness, and interaction were evaluated positively. Problems such as limitations of project classes due to non-face-to-face classes, large amount of learning before class, and reduced concentration during class were found. Therefore, when the FPBL class model is conducted non-face-to-face, it will be necessary to further strengthen the role of the instructor, provide lecture videos summarizing the core contents, and improve concentration by providing active participation and fun using various digital tools. The result of the study looks significant by confirming the possibility of applying FPBL model not only in design education but also other educational settings.

  • The objectives of this study were to introduce the easiest and most proper applications of datamining in industrial processes. Applying datamining in manufacturing is very different from applying it in marketing. Misapplication of datamining in manufacturing system results in significant problems. Therefore, it is very important to determine the best procedure and technique in advance. In previous studies, related literature has been introduced, but there has not been much description of datamining applications. Research has not often referred to descriptions of particular examples dealing with application problems in manufacturing. In this study, a datamining roadmap was proposed to support datamining applications for industrial processes. The roadmap was classified into three stages, and each stage was categorized into reasonable classes according to the datamining purposed. Each category includes representative techniques for datamining that have been broadly applied over decades. Those techniques differ according to developers and application purposes; however, in this paper, exemplary methods are described. Based on the datamining roadmap, nonexperts can determine procedures and techniques for datamining in their applications.

  • According to the change of customer needs, integration with other systems, and the advent of new technology, it is inevitable for the existing system requirements to be requested to redesign. However, there are actually no methodologies and processes to be able to reorganize the existing requirements or integrate a number of requirements different from each other. The traditional requirements processes do not work when solving such problems. Thus, since the existing approaches to develop requirements are not helpful, many traditional requirement engineering processes can not help falling in Red Ocean. In this paper, in order to solve such the problems, we propose a novel requirements engineering process applying Blue ocean strategy which is used to open a non-competition market not discovered yet. Blue Ocean approach is a novel effective method to elicit and build up new requirements from customers. In order to accomplish the strategy, this paper presents a framework and processes to discover new perspectives and analyze the corresponding requirements. In addition, some pieces of case study are presented to introduce how our approach is applied to practical system developments and the evaluation analysis for how valid it is.

  • Generally MPS, standardized by IBM, is the input type of large scale linear programming problems, and there may be unnecessary variables or constraints. These can be discarded by preprocessing. As the size of a problem is reduced by preprocessing, the running time is reduced. And more, the infeasibility of a problem may be detected before using solution methods. When the preprocessing implemented by this paper is used in NETLIB problems, it removes unnecessary variables and constraints by 21%, 15%, respectively. The use of preprocessing gives in the average 21% reduction in running time by applying the interior point method. Preprocessing can detect 10 out of 30 infeasible NETLIB problems.

  • DESIGNIN AND OPERATION OF DIGITAL EVIDENCE MANAGEMENT SYSTEM APPLYING COMPUTER FORENSICS AND ELECTRONIC CERTIFICATION Digital evidence will be used as a term, which means the electronic form of information which is necessary to confirm or prove the factum of all kinds of behaviors committed through the devices which have data processing ability including computer. It is expected that there will be the increase of legal conflicts surrounding electronic commerce activities as well as the increase of cyber crimes, as the number of Internet users are getting bigger. In order to solve the problems of conflicts derived from electronic commerce, the factum of electronic commerce activities must be confirmed. In order to confirm the factum of electronic commerce activities, the evidence is prerequisite. Almost all evidences relating to the electronic commerce activities exist in digital form. For the reason that the digital evidence can be easily damaged and changed, special management is required to collect, analyze, and preserve the digital evidence. In order to meet this requirement, this study proposes a basic model of digital evidence management system applying computer forensics and electronic authentication.
