The purpose of this study was to investigate how children with cochlear implants (CI) perceive emotion in music depending on mode and tempo cues, and to compare them to NH children. Participants in this study included 13 CI children who were implanted with either unilateral or bilateral cochlear implants aged between 7 and 13 years, 36 NH children, and 20 NH adults. The musical stimuli used in this study were piano recordings in either major or minor mode, with tempos of 130 bpm and 56 bpm. A comparison of the emotion perception levels of NH children and NH adults before the experiment showed that there was no significant difference between the two groups. Meanwhile, the way they perceive different emotions from each music condition varies, in that CI children perceived all music conditions except as happy, while NH children perceived music in a major key as happy and music in a minor key as sad. It supports that CI children tend to rely primarily on tempo cues to process and identify emotional information from music, which is contrary to NH children. It is important to note that this study enhanced and specified the understanding of how CI children perceive music emotion and use specific musical elements in the process. These findings indicate baseline data on emotion perception in music in CI children.

This study aims to examine effects of vision control balance training applied to stroke patients on their balance. 26 stroke patients, the subjects of this study, were divided into an affected side 1/2 vision control group (9), a non-affected side 1/2 vision control group (9), and a non-vision control group (8). After vision control standing on Posturo-med, all of the three groups received balance training 20 minutes four times per week for 8 weeks watching themselves 1M away from a mirror. To measure their balance abilities, measurements were made on their time of balance maintenance and muscle activity prior to the intervention, four 4 after the intervention, and 8 weeks after the intervention. Vision control balance training applied to stroke patients resulted in increase in their time of balance maintenance and significant improvement in vastus medialis muscle activity (p<0.05). This study result is that vision control balance training is considered an effective exercise method for balance training of stroke patients.

The aim of this study was to determine the effect of action observational physical training on upper extremity function and activities of daily living in stroke patient. 19 hemiparetic patients participated in this study and were randomly selected into an experimental group and a control group. An experimental group observed performance actions of purposeful activity task through a video and imitated actions with the traditional occupational therapy, and a control group only observed actions with the traditional occupational therapy. Traing was performed 3 times a week and 30 min for each round for 4 weeks. WMFT were performed for an upper extremity function and MBI were performed for activities of daily living. As a result, WMFT and MBI showed significant difference between before and after in two groups but didn't show significant difference between two groups.

When sharing real-time media in the ubiquitous computing environments, due to heterogeneous performance of devices, conflict to users' media service requirements might be occurred. To address the problems, there are extensive researches about media streaming QoS control schemes in the aspects of network or application. However, their deployment has met with difficulty because of critical reasons such as high development cost and system complexity. In this paper, in the level of media services, we propose a negotiation approach to offer improved quality of media services. The proposed approach Constructs video distribution group between producer and consumer services, which target to globally minimize the concession of users' quality requirements Consequently, users can be provided video services in the level of conformation to the users' expectation.

This study aims to study the change in the level of awareness of medical personnels regarding the patient safety culture(PSC) before and after the Leadership WalkRounds(LWR). The LWR in this study was based on the IHI and the models of the Patient Safety Rounds(PSRs) at University of Michigan, emphasizing the 5 steps of Preparation--Scheduling--Conducting--Reporting--Resolving. After the LWR the scores for the level of awareness showed a statistically significant increase from 2.63 to 3.36(p<.001). Among the participants, those who are pharmaceutists, women, 30.0~39.9 years old, or had work experience of a year or less showed particularly notable increase in awareness. The effect was significant across all categories of PSC, especially in Safety Accident Reporting(p<.001), then in Communication(p<.001). Therefore the LWR proved an convergent concept for applying new leadership skill and the concept of patient safety management as an method to elevate the frontline staffs' awareness of PSC.

The purpose of this study is to investigate the effect of 8 direction incline and rotation exercise on pain and dynamic balance in the patients with chronic low back pain(CLBP). 20 patients who were diagnosed with CLBP were included for the study. 10 patients(experimental group) were treated by modality{Hot Pack(H/P), Transcutaneous Electric Nerve Stimulation(TENS), Ultra Sound(U/S)} and then performed 8 direction incline and rotation exercise. The other 10 patients(control group) were only treated by modality. The therapeutic intervention was taken three times a week for 6 weeks. Dynamic balance was assessed by Star Excursion Balance Test(SEBT) and pain was assessed by Visual Analog Scale(VAS). VAS scores of both groups were decreased. However, the experimental group was more significantly decreased than the control group. The dynamic balance of both groups was significantly increased in anterior, posterior, medial, lateral direction. But experimental group was more significantly increased than the control group. In conclusion, 8 direction incline and rotation exercise was effective on pain and dynamic balance in CLPB.

This study is to conduct a 12-month f/u survey on changes of metabolic syndrome (MetS) components according to the resting heart rate (RHR) in patients with essential hypertension (HTN) without cardiovascular disease (CVD) complication. We used the KorHR (Korean Hypertension Registry) data and a total of 951 subjects were analyzed using the R statistical program. As a result of this study, it was found that the risk and changes of MetS components differs according to the RHR group with first and revisit hypertensive patients. Therefore, guidelines for customized RHR control for first and revisit hypertensive patients should be prepared. Also, it is necessary to prepare various interventions to control the RHR. Through this, it is intended to prevent the occurrence of CVD caused by HTN, which is a representative chronic disease, to improve the quality of life of patients and their families as well as to contribute to increasing the efficiency in the health care.

To explore the social construction of the concept of leadership, image of media mogul depicted in the popular business newspaper, the Wall Street Journal, was analyzed. Then, the reconstructed image of the CEO was compared with the firm's stock price change to see their relationship, if any. This paper focused on the case of Steve Case (previous chairman of AOL Time Warner), who was the leader of the world largest media company. The period for the analysis was three years and five months from his inauguration(January 2000) to the resignation(May 2003). In general, CEO of a firm represents the firm itself. Thus, the image of the CEO is highly transcends to the image of the firm as well. Consequently, the image of CEO might have an impact on the firm's performance. Since business newspaper works as one of the most important information intermediaries in the stock market, the image of CEO constructed in the newspaper might be a critical indicator for the investors. The results revealed that media coverage of Steve Case was commensurate with the financial performance, particularly stock price change of the AOL Time Warner.
