The purpose of this study was to elucidate the effects of music therapy on the preoperative anxiety of surgerial patients. The research design was a nonequivalent control, group non-synch-ronized design. The data were collected during the period from January 4 to March 17, 1999 at C-University hospital in Seoul. The subjects were sixty patients who had surgery under general anesthesia and had undergone laparotomy. They were assigned to two groups, thirty to the experimental group and thirty to the control group. They also did not have any complication, were alert enough to be interviewed and agreed willingly to participate in this study. The tool of Trait Anxiety Inventory was used to measure trait-anxiety on all patients and the Visual Analogue Scale(VAS) was used to measure state-anxiety on all patients. And systolic and diastolic blood pressure, pulse rate, and blood sugar levels were collected a the day before surgery and the preoperative period. The experimental group received music therapy with self-selected music tapes after choosing from a Music Preference Questionnaire, while the control group didn't receive music therapy. Data were analyzed by ${\chi}^2$-test, t-test, paired t-test. The results of this study are summarized as follows: 1. The preoperative state anxiety of the experimental group was re-markably lower than that of the control group. 2. Decreasing rate in the vital signs of the experimental group was remarkably lower than that of the control group. 3. The preoperative blood sugar of the experimental group was remarkably lower than that of the control group. According to these results, Music Therapy can be regarded as an effective nursing intervention that relieves preoperative anxiety of surgical patients and helper stabilize vital signs. From this study, the following recommendations can be made: 1. In order to decrease surgical patient's preoperative anxiety, I suggest the nursing intervention should go side by side with music therapy.

The theory of subjective preference with temporal and spatial factors which include sound signals arriving at both ears is described. Then, auditory evoked potentials which may relate to a primitive subjective response namely subjective preference are discussed. According to such fundamental phenomena, a workable model of human auditory-brain system is proposed. For eample, important subjective attributes, such as loudness, coloration, threshold of preception of a reflection and echo distrubance as well as subjective preference in relation to the initial time delay gap between the direct sound and the first reflection, and the subsequent reverberation time are well described by the autocorrelation function of source signals. Speech clarity, subjective diffuseness as well as subjective preference are related to the magnitude of inter-aural crosscorrelation function (IACC). Even the caktail party effects may be eplained by spatialization of human brain, i.e., independence of temporal and spatial factors.

Many online content providers who use the Internet to distribute contents, such as news, music, games, books, and other types of information, have been experiencing an extremely competitive business environment. To survive in this environment, they have started charging a fee for the contents that they provide. However, there have been very few success stories in commercializing online contents. One of the biggest hurdles may be customers' psychological resistance against paying a fee for the contents that have been free of charge previously. Without examining customers' perceived prices for online contents, many online content providers have tended to decide their prices by themselves. Online games are not exceptional cases. Although many online game-related research works have focused on psychological and technical aspects, very few works have examined online garners' preference carefully. This study alms at exploring online garners' preference by measuring their WTP (willingness to pay) for online games.

The demand and production for mobile music increases as the number of smart phone users increase. Thus, the standard of selection of a user's preferred music has gotten more diverse and complicated as the range of popular music has gotten wider. Research to find intelligent techniques to ingeniously recommend music on user preferences under mobile environment is actively being conducted. However, existing music recommendation systems do not consider and reflect users' preferences due to recommendations simply employing users' listening log. This paper suggests a personalized music-recommending system that well reflects users' preferences. Using AHP, it is possible to identify the musical preferences of every user. The user feedback based on the Bayesian network was applied to reflect continuous user's preference. The experiment was carried out among 12 participants (four groups with three persons for each group), resulting in a 87.5% satisfaction level.

Various room acoustic parameters and their optimal values were proposed and verified as proper interpretations to the listeners' preference of concert hall sounds. However the listening environment has been changed since they were developed, and the listeners' preference may not be the same among countries of different cultural backgrounds. Actual listeners' preference should be applied to the design of a new concert hall. A survey on the listening preference was carried out for 22 music experts. A room acoustical design process was proposed which made the acoustical environment of a concert hall as close to the listeners' preferences.

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.

Personalization recommendations have already proven in many areas of the e-commerce industry. For personalization recommendations, additional work such as reclassifying items is generally necessary, which requires personal information. In this study, we propose a recommendation technique that neither exploit personal information nor reclassify items. We focus on music recommendation and performed experiments with actual music listening data. Experimental analysis shows that the proposed method may result in meaningful recommendations albeit it exploits less amount of data. We analyze the appropriate number of items and present future considerations for contextual recommendation.

This study was initiated by the interest in identifying what the characteristics of BTS' preference is in the expanded K-Pop market. For this study, a survey was conducted to Taiwan, Thailand, Vietnam, and Korea where BTS is popular. The results of this study show that Vietnam and Thailand have the most positive perceptions of most of the BTS preferences, and the factors affecting the highest quality were analyzed by the differentiating sense of BTS. BTS' preference is an independent variable consisting of five factors: singers and music, a discriminative sense, global communication, meditative lyrics and Korean sentiment. And it has been shown to have a statistically significant influence on both the fandom star and the fan community at a high level. In particular, the Identification desire for fandom star shows that the discriminative sense and meditative lyrics affect the positive at a high level. Also, the identification desire for the fan community's found that the attraction of singers and music affects the highest level of affection. This study was extended to Southeast Asian and Korean fans through a wide range of survey participants, and it is meaningful that a new perspective on the BTS preference was available. Nonetheless, Failure to take into account the various variables that may affect the fandom effect and the intent to purchase, and the lack of a survey of fans in the U.S. and Europe, which has more fans worldwide, could be a limitation of the study.

The appearance of various mobile Internet environment access to existing networks of mobile devices is easier to tell. In addition, mobile device users to use the wireless environment than a wired environment, user profile information is readily available features. Mobile devices have features that use alone. These characteristics of mobile devices to apply the personalization service is the best system. This paper proposes for mobile device users a personalized mobile music content recommendation service. This service propose to utilizes the user's access history information using time-weighting and collaborative filtering. Access history information can find out information of user interest. Using this information, consider the preference of music genre and time-weighted based on the recommendations makes the music. This method the problem of the traditional music recommendation system, point user's favorite music genre is changing over time do not consider that to solve the problem.

This study examines the economic ripple effect of Korean wave(Hallyu). Specifically, this study tries to investigate how the satisfaction of Korean popular music among Chinese college students affects the purchase intention for Korean culture products such as Korea tour, the Korean language, and Korean martial art(Taekwondo). These products are not directly related to the Korean popular music. Results show that the overall satisfaction of Korean popular music leads to the preference for Korean popular music, which in turn improves the liking of Korean wave(Hallyu), the liking of Korea, and the purchase intention for Korean culture products. It is also found that the liking of Korean wave(Hallyu) affects the purchase intention for Korean culture products, which is mediated by the liking of Korea. However, the positive relationship between the liking of Korea and the purchase intention for Korean culture products is shown marginally significant.
