Objectives: This study was performed to determine the levels of depression symptoms among the community elderlies and to reveal its related factors, specifically aimed at revealing psycho-social factors such as social support net-work, sense of self-esteem, state anxiety, interpersonal behavior trait and locus of control. Methods: The interviews were performed during the period from April 1st to June 30th, 2007 to the 790 elderlies in urban and rural areas. Results: The mean scores of depression (CES-D) among all subjects were 16.65±10.97(urban: 18.81±10.31, rural: 14.49±11.20) and they were higher in urban than rural. The level of depression symptoms was influenced by the variables of educational level, with or without spouse, bear for living expenses, sense of satisfaction in daily life. As for health related behaviors, they were influenced by the variables of with or without regular exercise. As for health status, they were influenced by the subjective health status, with or without disability of body, visual acuity, hearing ability, ability of food mastication, urinary incontinence, with or without help in activity of daily living (ADL) and instrumental activity of daily living (IADL). As for social support net-work and social activities, they were influenced by number of offspring, frequency of offspring contents, frequency of going out and activity of hobbies. As for psycho-social factors, they were influenced by sense of self-esteem, state anxiety and social support, especially, the level of depression symptoms was higher influenced by the variables of psycho-social factors than other variables. Conclusions: Lower of the level of depression symptoms among the community elderlies would require development and application of programs to keep under management psycho-social factors as well as looking for ways to promoting the present health status.

Background: The International Classification of Functioning, Disability, and Health-core set (ICF-core set) for children and youth (CY) with cerebral palsy (CP) provides a useful conceptual framework and a guide for health care planning and measuring the changes brought by interventions across a multitude of dimensions from body functions to personal activities, social participation, and environmental factors for them. Objects: This single case study was reported to illustrate the use of a goal directed approach in applying the ICF-core set for CY with CP from a physical therapist perspective. Methods: An eleven year old boy with spastic CP, Gross Motor Function Classification System (GMFCS) level V, and his mother participated in an evaluation of his functioning state. The intervention goal was set through an interview using the ICF-core set, Canadian Occupational Performance Measure (COPM) and Goal Attainment Scale (GAS). Physical therapy was carried out on an outpatient basis using a goal directed approach for 30 min, 1 time/week during 12 weeks and the boy's gross motor function was assessed using the Gross Motor Function Measure (GMFM)-66 version (item set 2) before and after the intervention. Results: As measured by the boy's mother, the COPM score showed a meaningful clinical change (performance=mean 3.5, satisfaction=mean 2.5) and the T-score of GAS changed 34.4 after the goal directed approach. The GMFM-66 (item set 2) score changed from 31.8 to 38.7 and evaluation using the ICF-core set displayed improvement in 6 items of activity level between before and after the intervention. Conclusion: The ICF-core set for CY with CP is useful for understanding the overall functioning of CY with this condition and provides an opportunity to share and integrate information and opinions from different disciplines. We consider it as a useful tool in the universal language for the therapy and education of CY with CP.

This study was carried out to identify factors related to breakfasts in elementary, middle and high school students. This study was surveyed by questionnaires and data was analyzed by SPSS program. Exploratory analysis was conducted according to three school student groups (elementary children, middle school students, and high school students). The subjects were 1,886 school students (female 893, male 959) of 51 schools in the nationwide region. The distribution of subjects was elementary school children 544, middle school students 661 and high school students 681. The results are summarized as follows. Only sixty percent of the subjects had breakfast regularly. About one fourth of the subjects had the habit of skipping breakfast or eating it 2$\sim$3 times per week. Frequency of having breakfast and reasions of skipping breakfast were significantly different according to school student groups (p < 0.001 respectively). The rate of skipping breakfast was $14.4\%$ in elementary school, $16.1\%$ in middle school, and $25.0\%$ in high school. The main reason for skipping breakfast was 'not delicious or poor appetite' in elementary school ($42.5\%$), but 'busy' in middle ($50.2\%$) and high school ($61.1\%$). There was no significant difference in frequency of having breakfast according to living areas (rural and urban). There were not significant differences between frequency of having breakfast and BMI and degree of satisfaction on body weight. But there were significant difference in frequency of having breakfast according to economical status (p < 0.05). There were significant differences in degree of school performance according to frequency of having breakfast (p < 0.001) There was significant relationship between the time of attending school and the frequency of having breakfast. But there were significant relationships between frequency of having breakfast and time of rising. These findings suggested that the time of rising was controlled by having enough time that students eat breakfast. And mother (or person who prepares meals) must have more concerns about preparing breakfast for children and students.

Vacuum cleaner is a close life product that can remove various dusts from our surroundings. However well vacuum cleaner clean our environments, many people are looking away from it, due to its loud noise. Its noise causes a big trouble in the usual life, for example, catch calls, TV watching and discussing etc. To reduce these inconveniences, noise reduction methods and systematic design of low noise vacuum cleaner are studied in this paper. At first, sound quality investigation is performed to get the noise level and quality that make people TV watching and catch calls available. Based on the European and domestic customer SQ survey result, sound power, peak noise level and target sound spectrum guideline are studied and introduced. As a second, precise product sound spectrums are designed into each part based on the sound quality result. Fan-motor, brush, mainbody, cyclone spectrums are decided to get the final target sound based on the contribution level. Fan-motor is the major noise source of vacuum cleaner. Specially, its peak sound, RPM peak and BPF Peak, cause the people nervous. To reduce these peak sounds, high rotating impeller and diffuser are focused due to its interaction. A lot of experimental and numerical tests, operation points are investigated and optimization of flow path area between diffusers is performed. As a bagless device, cyclones are one of the major noise sources of vacuum cleaner. To reduce its noise, previous research is used and adopted well. Brush is the most difficult part to reduce noise. Its noise sources are all comes from aero-acoustic phenomena. Numerical analysis helps the understanding of flow structure and pattern, and a lot of experimental test are performed to reduce the noise. Gaps between the carpet and brush are optimized and flow paths are re-designed to lower the noise. Reduction is performed with keeping the cleaning efficiency and handling power together and much reduction of noise is acquired. With all above parts, main-body design is studied. To do a systematic design, configuration design developments technique is introduced from airplane design and evolved with each component design. As a first configuration, fan-motor installation position is investigated and 10 configuration ideas are developed and tested. As a second step, reduced size and compressed configuration candidates are tested and evaluated by a lot of major factor. Noise, power, mass production availability, size, flow path are evaluated together. If noise reduction configuration results in other performance degrade, the noise reduction configuration is ineffective. As a third configuration, cyclones are introduced and the size is reduced one more time and fourth, fifth, sixth, seventh configuration are evolved with size and design image with noise and other performance indexes. Finally we can get a overall much noise level reduction configuration. All above investigations are adopted into vacuum cleaner design and final customer satisfaction tests in Europe are performed. 1st grade sound quality and lowest noise level of bagless vacuum cleaner are achieved.

TQM is a whole process of systemizing, documenting and measuring of service quality scientifically to achieve zero defects in product quality and to continue to improve the body of the product quality by itself. To have this process be improved continuously, first of all it needs to prepare an ideal environment to understand and to conform to its internal and external customers', that is every guests' and employees' expectations and demands. Then it has to be followed by the next step removing some negative aspects that could be derived from the first mentioned process The third step is to cut the cost be suitable compensation rather than an attitude trying to solve the problems in an easy way. The last essential factor for setting up TQM system is to make good use of the outstanding feature or process as it is reviewed against the superior benchmark. The purpose of this study is meet the customers' expectations and to maximize the hotel's profits by searching TQM(total quality management) strategy in hotels. To attain this research's objective, it follows these three details. Firstly, it defines TQM and its contents. Secondly, it provides the standard of hotel TQM throughout some case studies. Thirdly, it suggests TQM strategic plan in tourism hotel as one of professional management strategies. Two useful methods are used together to achieve the goal of this study. To confirm its theoretical consideration, descriptive studies by the research documents its theoretical consideration, descriptive studies by the research documents published in and out of the country is used. The other is case studies of TQM execution in real hospitality industry, which present the cases of the airline, Jefferson Memorial and the hotel. This research is targeting to demonstrate the successful TQM's exercise in a hotel industry by completing the theoretical studies and case studies on service product quality with an understanding of its importance. As it is said earlier, to lead to the successful TQM's practice, it is necessary to maintain a constant training of the employees. Secondly, it also must identify where it has to focus on to deliver a professional quality management. Thirdly, effective quality management organization needs to be build up. The manager's strong will to accomplish and the employee' active participations are the last condition to be succeed. Once again this study places an emphasis on the fact that TQM is critical to maximize the customers' satisfaction and the hotel's profitability. It is also very worthwhile to have every people working on front line recognize why the TQM is important and further more how they can contribute to improve their service quality by a positive participation and a careful observation of TQM's operating in their property.
