IT 와 비즈니스가 융합화 되고 정보가 디지털화 됨에 따라 그에 대한 저장매체도 점점 더 다양해지고 있다. 그 중 이동성이 편리하고 휴대하기 간편한 스마트폰을 활용하여 개인 정보를 주고 받고 이를 이용한 비즈니스가 현재 활발히 진행되고 있다. 이러한 소셜 네트워크 서비스 이용이 급격히 증가함에 따라 개인 정보 보안에 대한 중요성은 점점 더 강조 되고 있는 실정이다. 본 연구에서 제안하는 디지털 포렌식 분석 방법을 이용하면 스마트폰에서 지원하는 서비스 형태에 따라 텍스트, 이미지, 동영상 등의 개인 정보를 수집 및 분석이 가능하다. 또한 디지털 포렌식의 관점에 따라 스마트폰 에서 사용되고 있는 애플리케이션의 로그 정보를 수집 및 분석함으로써 스마트폰의 저장 장치에 남겨진 기록들을 훼손 없이 그대로 보존시키고 디지털 증거 자료로 활용이 가능해 사이버 범죄에 대한 신속한 해결이 가능하다.

지속되는 기후변화에 의한 풍수해의 발생 빈도와 강도가 증가함에 따라 풍수해 등 극한 기상현상이 지역 및 상황에 따라 재난으로 이어지는 위험성이 높아지고 있어 기상정보 사용자 및 환경에 따라 서로 다른 기상정보의 중요성과 필요성이 급증하고 있다. 이와 같은 수요를 맞추고자 기상 재난에 의한 피해 위험 지역 거주 주민과 재난 현장에서 재난에 대응하는 방재 관계기관 등 특정 사용자의 요구와 필요에 특화된 맞춤형 기상긴급정보를 다양한 매체의 특성에 맞게 즉각적으로 생성하여 전달하기 위한 기상긴급정보전달시스템이 개발되고 있으며 인공지능을 활용한 긴급성의 식별과 정보 생성 방안이 연구되고 있다.

A development of the Digital Media through media convergency is creating various contents business. Basically, contentware can be explained as something watching, listening or enjoying. It has been developing to tie a moving image with a sound and a game; something that was in the entertainment business in the past. The good way to get an insight on effectiveness of the multimedia contentware would be though the understanding of the change of communication style in digital medium. Thus, this paper covers the effectiveness problems in the semantic level rather than the accuracy and efficiency in the syntactic level in the digital media mediated communication. As the trends of the media cornsumption is moving toward more an interesting way, it is essential to build up commoness in terms of sympathy between a contentware and user. So this paper introduces the concept of commom fields of experience through the fundamentals of the phatic communication as a way to architect the multimedia content effectively.

IPTV, a convergence service of broadcasting and communication, draws an attention as an educational media that provides various advantages including top quality of screen, easy access, and protection from harmful contents. In addition, a successful IPTV learning requires learners' active participations. Yet, the research on educational applications of IPTV is at the early stage focusing on teachers and developers' perspectives. Therefore, the present study conducted a survey on learners' current IPTV usage and intentions to use. Reflecting the results of the survey, we developed learner-centered IPTV learning scenarios based on self-regulated learning strategies and suggested its implementations.

The floating holograms currently being commercialized are one-way floating holograms. One-way floating holograms are used for performances and exhibitions, and the implementation method is to reflect the image contents into the reflecting glass at $45^{\circ}$ through a single presentation medium. This creates as inefficient a space as the remaining space of reflective glass tilted at $45^{\circ}$, and even more inefficient space if the video content is presented larger. Therefore, the installation space of a one-way floating hologram is restricted. This paper aims to improve users' satisfaction by developing an upper and lower floating hologram with efficient installation of a one-way floating hologram that is currently commercialized, integrating sound output systems and producing new types of speaker products.

The purpose of this research was to explore the phenomenon of object relations with musical instruments as experienced by professional Samulnori musicians. The researcher conducted in-depth individual interviews with five Samulnori players who also completed questionnaires with open-ended questions. The data were analyzed using Giorgi(2004)'s phenomenological methodology. The results offered 121 semantic units, seven subcategories, and three main categories. The three main categories were transitional object, object of expression and recognition of internal desires, and object for recognition of others and communication. These results suggest that the ensemble format of Samulnori promotes the development of the musician's object relationship and can externalize the player's internalized representational system and interaction method. This study is significant in that it reveals the endopsychic functional relationship between a musician and their instrument and provides the basis for the use of Samulnori instruments in music therapy.

The purpose of this study is to explore the effectiveness of teacher education using applications. To do this, we conducted research on pre-school teachers. To summarize the performance of the study, it is as follows. Teacher training was conducted through music creation activities. The subjects of the study were 56 students(29 experimental group, 27 control group) in early childhood education of A University located at Gyeonggi, Korea. The music creation activities using the application were conducted on the 10th week and the experimental research was carried out. Analysis of the difference between the experimental and control groups in the pre-test and post-test, showed a statistically significant effect on belief in musical teaching efficacy of the control group. The results showed that the teachers' positive attitude toward the role of teacher in the teacher education program using the application was positively influenced. The results of this study by taking advantage of new educational media of applications in teacher education and to provide a basis for exploring concrete action plans for utilizing the application in the teacher training curriculum for future educational.

This study is to empirically investigate the impact of product placement on purchase intention. Product placement is growing due to its advantages that it is cheaper than general advertising and free from restrictions from exposure time. Considering that, this study includes variables reflecting high importance and characteristic changes in product placement. The study selects fashion involvement, celebrity involvement, bald exposure, and exposure strength as variables reflecting the unique characteristics of product placement, observance of ethics and consumer deception as ones reflecting ethical aspects, and program popularity and media familiarity as variables reflecting means of using product placement. As a result, celebrity involvement and program popularity have a positive influence on purchase intention, and consumer deception has a negative impact. However, fashion involvement, bald exposure, exposure strength, observance of ethics, and media familiarity do not have a statistically significant impact. This study explains the results through comparison with previous studies and suggests implications based on the association between product placement and purchase intention.

The purpose of this study was to explore the experiences of counselors who conducted video counseling using digital mask. To this end, the contents of the focus group interview with four counselors who experienced mask video counseling for a total of 10 Korean college student clients were analyzed using thematic analysis method. Participant counselors reported that they had been concerned about mask video counseling before the start but gradually be adjusted to the method. Since they have observed the rapid self-disclosure of the clients and smooth counseling process, they positively predicted the possibility of digital masks as a therapeutic media. They also mentioned the need for additional education and training for the counselors who are using the new on-line counseling media. Therefore, various supports for proactive responses of counselors to online counseling media need to be explored.

In recent years, the digital media environment has begun to diversify, with a greater focus being placed on user-centric design. With the development of digital technology, the digital media environment has formed a vast network of information, which supports interactive communication between people, creating a need for user-centric research. Mobile displays, as a representation of the digital media environment, have the advantage of mobility through the use of thin screen displays and low-performance image sensors, which allow for miniaturization and power saving. However, this results in reduced colour accuracy compared to large displays. This study investigates users' colour perception when using dark and light mode mobile displays. Colour perception was measured using a psycho-physical experiment, which controls each colour attribute based on the 12 colours of KS. The results were analysed to determine whether there is a difference in colour perception between dark mode and light mode, and if the difference was statistically significant. Future research directions based on the results are then discussed.
