Previous studies of music, user interface, and human-computer interaction have used sounds which include musical structure rather than real music. This study investigated whether real music affects objective and perceived usability. Silence, sound, and music conditions were compared in experiment 1 (kimchi refrigerator) and 2 (remote controller for air conditioner). Participants' performances of reaction time and accuracy, and the degree of subjective satisfaction were analyzed. The results showed that main effects on task performances were not different significantly; however, perceived usability of music condition was better than sound condition, which was better than silence condition. It means that musical user interface improves perceived usability while not interfering task performance. This study provides a basis of emotional and aesthetic effects of music in home appliances design, and can be applied to studies for the blind. More specific guideline for the musical user interface can be drafted if further studies consider more various tasks, context, musical structure and types for the appliances.

Objectives: This study was conducted to evaluate hand-arm vibration (HAV) exposure levels due to the use of power hand tools and to evaluate the determinants in the automobile assembly process. Methods: The exposure level to HAV was evaluated for 30 work lines in five assembly processes (body, engine, chassis, door, and design) that use air-powered tools and battery-powered tools and operate in circulation for two hours. The 2-hr equivalent energy vibration acceleration, A (2), of the task was measured. The 8-hr equivalent energy vibration acceleration, A (8), was estimated in consideration of the number of tasks that can be performed per day by each process. In addition, a survey on the working environment was conducted with workers exposed to vibration. Results: The geometric mean of the HAV exposure level, A (2), for a total of 30 tasks was 2.51 m/s², and one case was 10.30 m/s², exceeding TLV (2hr). The HAV exposure level of A (8) was evaluated from 1.03 m/s² to 5.36 m/s². A (2) showed a statistically significant difference (P<0.01) for each process, and the chassis process (GM=3.90 m/s²) was the highest. The larger the tool size and the longer the tool length, the higher was the vibration acceleration when using a battery-powered tool than an air-powered tool (P<0.01). Battery-powered tool users showed higher dissatisfaction on all items than did air-powered tool users. Conclusions: As a result of this study, it is necessary to implement a program to reduce the HAV exposure levels.

The job of dental hygienists is specialized, and they have to be capable of performing their primary duties including prevention of oral diseases, oral prophylaxis, and oral health education. To ensure their successful job performance, dentists should have an accurate understanding of their duties and need a change of mind-set about them. And there should be written legal and concrete regulations on the coverage of their work in order to let them boost their job performance with pride and a sense of responsibility. The purpose of this study was to examine the actual roles and job performance of dental hygienists in clinical field in an attempt to discuss the substantial job performance of dental hygienists and their job enlargement. It's basically meant to help enhance the efficiency and quality of medical services. The subjects in this study were 471 dental hygienists in dental clinics, dental hospitals, university hospitals and general hospitals across the nation, on whom a survey was conducted in person from March 2 to 25, 2005. The collected data were analyzed with SPSS Win 12.0 program, and the findings of the study were as follows: 1. The major jobs they currently performed included oral health education, hospital management, simple duties, extensive dental hygiene duties and joint treatment assistance. They hoped to continue to be responsible for oral health education, preventive treatment and extensive dental hygiene duties. 2. As for their current job by age, extensive dental hygiene duties, preventive treatment, joint treatment assistance, preserving treatment, prosthetic treatment and pediatric treatment were most conducted by the dental hygienists who were at the age of 26 to less than 31, and those who were at the age of 31 and up were most responsible for hospital management and simple duties. 3. As to job awareness by workplace, their workload was statistically significantly different according to their workplace. The hospital employees took care of more work than those in clinics. 4. Concerning job awareness by age, the younger dental hygienists suffered more role conflicts and were given a less free hand in work handling, the middle-aged group's job was uncertain. Legal regulations about the coverage of their work should be prepared in detail as a measure to stir up their responsible job performance and pride. In order to take advantage of experienced dental hygienists, their duties should be more differentiated and specialized, and their working conditions should be improved to boost their job satisfaction. That is, they should be given ample chances for promotion and serving as a middle manager and be given fair treatment according to their career. If their work is accurately darified and specialized based on career, it will boost the efficiency of dental treatment. Dental hygienists also should direct sustained efforts into self-development in order to become a skilled and professional oral health personnel.
