모바일 기기는 기존의 음성통화에서 다양한 네트워크 접속과 전자기기 기능들이 결합되어 무선 서비스와 보완적으로 발전하고 있다. 다양한 휴대 인터넷 환경의 출현은 기존 모바일 기기의 네트워크 접근을 보다 쉽게 해주고 있다. 또한 무선 환경을 사용하는 모바일 기기 사용자는 유선 환경보다 사용자 프로파일 정보를 쉽게 구할 수 있는 장점이 있으며, 모바일 기기는 혼자 사용하는 특징을 가지고 있다. 본 논문에서는 모바일 기기 사용자를 위한 모바일 음악 개인화 방법으로 협업 필터링 방법을 통한 음악 추천과 다운로드 서비스 방법을 제안한다. 모바일 기기 사용자 프로파일 정보는 협업 필터링 방법을 통한 사용자 선호 음악 추천을 수행하고, 추천된 사용자 선호 음악은 모바일 기기로 다운로드 서비스를 수행한다. 추천을 통한 모바일 음악 다운로드 서비스는 모바일 기기 사용자로 하여금 무선 환경에 접속되어있을 때 사용자 취향에 맞는 음악을 미리 다운로드 해 둠으로써 사용자가 음악을 선택하여 모바일 기기로 다운로드 하는 시간을 줄여 줄 수 있다.

휴대용멀티미디어플레이어(이하 PMP)는 2004년 국내에 등장하여 음악과 더불어 영화 및 동영상을 볼 수 있도록 해주고 있는 인기 있는 개인용 전자기기이다. 그러나 수요가 둔화되고, 업체들의 경쟁이 치열해지면서 새로운 기능, 새로운 서비스에 대한 개발이 대두되고 있다. 최근에는 네비게이션 서비스, 학습서비스가 시행되면서 다시 수요가 살아나는 추세이다. 이에 따라 현재 존속하는 서비스에 대한 평가 및 새로운 서비스에 대한 검증이 요망되고 있다. 본 연구에서는 소비자 니즈 조사를 분석함으로써 현재 이용되고 있는 서비스들의 상황을 분석하고, 신규 서비스에 대한 수요 가치를 분석하였다. 분석 대상이 된 기존 상용 서비스는 게임, DMB, 영화, 음악, 네비게이션, 전자사전, 전자책, 이러닝, 만화, 무선인터넷였고, 신규 서비스는 u-Commerce, u-Health, u-Security, u-Public였다. 본 연구결과 PMP 응용 수요선호도 순위는 영화, TV, 음악 순이었으며, 신규서비스 u-Commerce, u-Health, u-Security, u-Public 옵션들에 대한 구매의향 평균가는 68,102원으로 나타났다.

The purpose of this study was to examine the use of music for job stress of employees in highway service areas and differences in use of music. For this, a survey was conducted on 150 respondents of U city and G province. The questionnaires were composed of a total of 53 questions, including use of music 25, job stress 24, and demographic characteristics 4 questions. A total of 150 questionnaires were distributed and 134 were analyzed. As a result, first, the respondents preferred listening to music over playing instruments or singing and mostly listened to popular music at home alone. Second, they reported that their purpose of use of music was for mood change followed by comfort, joy, sense of vigor, and sense of relief. Third, there were significant differences in mood of music and degree of achieving sense of relief through music. This study could provide information for organizing effective convergence music programs which could meet the needs and demands of them.

The purpose of this research is to find out the effects of music therapy activities using preferred music on job stress, work engagement and flourishing of reporters in broadcasting company. The study targets 51 reporters in S city, with the experimental group consisting of 20 reporters from A broadcasting company and the control group composed of 31 reporters from A newspaper company. The experimental group voluntarily listened to preferred music at least three times a day for two weeks, while the control group did not perform any activities. For data analysis, the job stress scale, work engagement scale, and flourishing scale scores of each group were collected right before and after the experiment, and the results of the analysis were as follows. First, the experimental group's job stress decreased, and significant score differences were also shown in comparison with the control group. Second, work engagement also increased by a noticeable difference. Third, in the case of flourishing, the after experiment's average value rose slightly, but the difference was not statistically significant. In conclusion, this research offered implications for the need for a music therapy activity program to recover from reporters' job stress circumstances and discussed the need for further research.

While we are driving a car, we are able to listen to musics by two ways: by selecting (manipulating) what we want and by just playing as they are given (in CD). These methods make a driver tired while he is driving or it means that a music which is provided is not concerned with a driver's preference. To improve these problems, there have been many studies about the automatic music providing systems based on driver's emotion. However, these studies have some difficult problems: the first one is that it is not easy to determine driver's emotion, and the other one is that it is hard to recommend and play the suitable music corresponding to the determined user's emotion. In this paper, to overcome the second problem mentioned above, a new mapping method between driver's emotion and music genre for automatic music providing system on vehicle is presented and two experiments are examined for the validation of the proposed method. The experimental results and discussions are explored to show the effectiveness and validity of the proposed method.

This paper is a study that analyzes the use and techniques of rap in music that entered Melon Chart, one of the major music sites in Korea, during 2020. Among the songs that entered the chart, reflecting the public's preference, the trend of rap music, an important element of hip-hop music, is analyzed and musical features such as representative artists or frequently used rhythm patterns are analyzed. Through this paper, characteristics of rap music favored by the public and artists in recent popular music have been organized and formalized, and based on this, the elements of etude development for technical polishing are summarized. Through this, it is hoped that just like the long-time analyzed and structured performance techniques such as vocals and instruments, various styles of rap music can develop into a systematic and step-by-step technique system for students who want to learn and practice it.

In this paper, we propose Context-based Music Recommendation (COMUS) ontology for modeling user's musical preferences and context and for supporting reasoning about the user's desired emotion and preferences. The COMUS provides an upper Music Ontology that captures concepts about the general properties of music such as title, artists and genre and also provides extensibility for adding domain-specific ontologies, such as Mood and Situation, in a hierarchical manner. The COMUS is music dedicated ontology in OWL constructed by incorporating domain specific classes for music recommendation into the Music Ontology. Using this context ontology, we believe that the use of logical reasoning by checking the consistency of context information, and reasoning over the high-level, implicit context from the low-level, explicit information. As a novelty, our ontology can express detailed and complicated relations among the music, moods and situations, enabling users to find appropriate music for the application. We present some of the experiments we performed as a case-study for music recommendation.

The purpose of this study was to compare participants' perceived emotion following harmonic changes in music. In this study, 144 participants, aged 19 to 29 years, listened to music online that included low to high harmonic progression in tonal music (major-minor). After listening to each piece of music, participants were asked to rate 4 items using a 7-point Likert scale: emotional potency, arousal, degree to which the harmony impacted the listener's emotions, and listener's preference for the music. There were significant differences between each of the four items upon the level of harmonic progression. When the participants were divided into two groups (i.e., those with a background in music and those with no background in music), there was a significant difference between the groups in terms of emotional potency, but there was no significant interaction effect. This study confirmed that various emotional responses in listeners can be induced by controlling the exogenous variables in musical excerpts. Based on this, it is expected that the harmonic progression level can be provided to the client to be used as an effective therapeutic tool in music therapy intervention.
