As digital media technology continues to evolve, media arts are being created using new technologies. Among them, interactive media provides new experience and interest to the audience in that the audience is completed only by participating in the works. The use of these characteristics as a marketing strategy has led to an increase in sales and a positive image of the company. Through this study, we analyze the case of interactive media contents and infer the usage plan and elements. In addition, we propose a prototype of interactive media contents that can be used as a strategic marketing element by exploring ways to utilize interactive media as a marketing element of the film industry. This suggests the development direction of interactive media that provides a continuous and new sense of immersion to the audience, and suggests subsequent research on effective use of the industry as well as movie marketing.

The recent software education in middle schools is focused on physical computing, unplugged learning and pilot training. However, they are struggling in many ways, including cost, inducement of interest, motivation, and concentration. Also, the lack of systematic classroom design could make negative effect to students' understanding of classes or academic performance. In this paper, we intend to study the method of algorithm education using Chatbot system, which will increase efficiency of software education, with less burdensome in terms of cost, and also could be able to used as an assist tool in various classes. In class scenarios that require the understanding of coding mechanisms such as function application, algorithm design, and program coding, students can learn by themselves through the Chatbot system, which has a positive effect on student learning.

Most existing mobile distance learning systems are asynchronous ones that allow students to download lecture video and presentation material. However, there are a few synchronous real-time mobile distance learning systems that support slide, annotation, feedback from student, and lecture video and audio at the same time. These live mobile distance learning systems have an advantage of supporting real-time interaction between students and a lecturer thereby making students understand the lecture better. But, they also have a disadvantage in the sense that they don't allow students to experience the past lecture. This problem can be solved by recording and replaying lecture session. So far, there are few mobile distance learning systems that support session recording and replay. This paper presents a synchronous mobile distance learning system that supports video and audio, slide with annotation, and real-time feedback from students, as well as session recording and replay, which is not supported by the existing mobile distance learning systems. The evaluation of the system among students shows that 61.3% of them were satisfied while 3.2% weren't.

The rapidly changing 21st-century knowledge and information society is emphasizing converged education that crosses various academic fields. In particular, the society expected the cultivation of the talent who balance scientific creativity and artistic sensitivity by adding arts to the existing converged education revolving around science and technology. However, at present, most STEAM education has been actively conducted with a focus on science and technology, whereas the subject of arts has been regarded or utilized as a supplementary means. Its problem is that the educational characteristics and values of art education have not been effectively utilized in educational terms and this could lead to superficial integrated education. In this respect, this study had the knowledge of various fields, such as science, technology, and mathematics, utilized usefully during the process of experiencing and creating arts. Accordingly, this study designed an education programs as with the case of Nam-Jun Baek who expanded the dominion of arts by creatively utilizing his own time's scientific technologies. In this educational process, the target program was developed in a manner that enables EPL to be utilized essentially as the study's knowledge-based tool and medium. The results of applying this educational program in 5th-grade elementary school students showed that the program has positive effects on the creative attributes of the students.

This study conducted both a content analysis and Q-methods analysis in order to find media coverage and recognition type of users about ubiquitous environment in digital online age. The perception type of this study were divided into four types in all through Q-methodology. Above all, this study investigated three research problems. First, how is the type of the perception divided into the subjectivity by recognition-characteristic on ubiquitous environment in Korea? Second, what is a trait of character in these same or different types? Third, how did news media cover ubiquitous phenomena overall? Fourth, is there any difference between media coverage and audiences' perception about ubiquitous phenomena? The results show that audiences seem to generally follow the frames that mass media provide. In addition, however, the audiences tend to recognize ubiquitous environment based upon their own schema as following four types: 1. Positive Universality Leading Type, 2. Uncertain Prudence Preference Type, 3. Future Cultural Enjoyment Type, 4. Negative Effect View Type. This study suggests that every efforts such as technology and policies that can improve the quality of ubiquitous environment in Korea should be accompanied.

The importance of interface agent as user interface increases in the ubiquitous computing environment. It is essential that an interface agent can develop social relationship with users. We propose that self-disclosure, a major factor to form and maintain human relationship, can be useful to achieve this goal. This study examined the effects of the degree of a computer agent's self-disclosure on the users' social responses. The experiment was conducted in a 2(intimacy of agent's disclosure: high vs. low) by 2(amount of agent's disclosure: high vs. low) between-group design. The results show that: 1) reciprocity of self-disclosure was found in both sub-dimensions (intimacy and amount) of self-disclosure; 2) in case that participants received highly intimate self-disclosure from the agent, social attraction, trustworthiness and expectation of mutual influence toward agent were lower than when the agent's disclosure was less intimate. These findings suggest that the intimacy of agent's self-disclosure can affect on gathering user information and human-agent relationship formation separately. While agent's highly intimate disclosure can be useful to gather user information, agent's appropriate disclosure can be useful to form positive user-agent relationship.

The biggest paradigm of the latest telecommunications is ubiquitous computing. It is a technology basis to realize ubiquitous society that would affect social, economical and cultural industries with positive influence. However, there is a simultaneous concern that the approach to ubiquitous society may violate one's privacy. Therefore, the existence of legal and technological regulation would be the biggest obstacle in further RFID technology and industry dissemination. Also, in business side, they must invest with enormous expense and technology if technological method is only approached for the solution. As in the research, 8 RFID applications, application process and inspection items and 85 appraisal list of "An impact assessment for the privacy protection in RFID applications" developed by P. K. Han(2006), will be used as an indicator to measure RFID privacy impact assessment. In addition, it is to develop RFID privacy impact assessment index by applying objective data with survey of applied specialists. This would provide a data with feasibility and reliability to RFID related companies and able to utilize policy making on RFID private data. In addition, it is expected to contribute as an efficiency tool for individual data to build basis of ubiquitous society.

Since the invention of the integrated circuit (IC) in 1950s, semiconductor technology has undergone dramatic development up to these days. A complete semiconductor is manufactured through a diversity of processes. For better semiconductor productivity, fault detection and classification (FDC) has been rigorously studied for finding faults even before the processes are completed. For FDC, various kinds of sensors are attached in many semiconductor manufacturing devices, and sensor values are collected in a periodic manner. The collection of sensor values consists of sequences of real numbers, and hence is regarded as a kind of time-series data. In this paper, we propose an algorithm for detecting and clustering faults in semiconductor processes. The proposed algorithm is a modification of the existing anomaly detection algorithm dealing with symbolically-represented time-series. The contributions of this paper are: (1) showing that a modification of the existing anomaly detection algorithm dealing with general time-series could be used for semiconductor process data and (2) presenting experimental results for improving correctness of fault detection and clustering. As a result of our experiment, the proposed algorithm caused neither false positive nor false negative.

The purpose of this study is to develop and apply a Design Thinking-based Maker education program utilizing Arduino for middle school students. The study progress was made in four stages of preparation, development, implementation and evaluation according to the PDIE model. In this study, experts were verified for validity and pre-applied to students to improve the maker education program developed based on literature review. Then, it was applied to middle school club classes to check the effects through analysis of quantitative and qualitative data. In addition, the development of the program was completed by supplementing the improvements found in the course. The results of this study are as follows. First, the topics of the maker education program that can be used in middle schools were selected in consideration of the analysis of the 2015 revised curriculum, methods to using the Arduino, and social interest. Second, the program developed based on the selected topic consists of 4 classes of maker basic learning and 16 classes of design thinking-based maker activities. Third, the developed maker education program had a significant effect in improving STEAM literacy of middle school students, but did not have any significant effect in the interest in technology and orientation towards an engineering career. Fourth, learners were interested in the activities of designing and freely making by themselves, and they positively evaluated the experience of realizing the physical computing with Arduino. In addition, they practiced the spirit of a maker, such as autonomously collecting data and sharing them with colleagues, etc. while acting as a maker.
