Purpose: Purposes of this study were to develop a community-based respite program for family caregivers and to test the effects of the program. Methods: Focus group interviews were performed to extract meaning of respite care for family caregivers (13 participants) and a survey was done to identify respite needs of family caregivers (157 participants). The community-based respite program for family caregivers was developed based on results of the focus group interview and survey. The program was used with 41 participants (19 experimental and 22 control). Independent t-test and Mann-Whitney U-test were used to test differences between control and experimental groups for respite needs, burden of caregivers, subjective wellbeing, social support, fatigue and functional status of elders with dementia. Results: There were statistical differences in caregiver burden, subjective wellbeing, and social support after the program, but, none for respite needs, fatigue and functional status of elders with dementia. Conclusion: The results indicate that a respite program can be useful to decrease burden of caregivers and increase subjective wellbeing and perceived social support of family caregivers in community settings. Further intervention research is needed to increase the functional status of elders with dementia and decrease fatigue in caregivers.

Objective: The aim of this study is to investigate and review the previous researches about objective measuring fatigue caused by visual stimuli. Also, we analyze possibility of alternative visual fatigue measurement methods using facial expression recognition and gesture recognition. Background: In most previous researches, visual fatigue is commonly measured by survey or interview based subjective method. However, the subjective evaluation methods can be affected by individual feeling's variation or other kinds of stimuli. To solve these problems, signal and image processing based visual fatigue measurement methods have been widely researched. Method: To analyze the signal and image processing based methods, we categorized previous works into three groups such as bio-signal, brainwave, and eye image based methods. Also, the possibility of adopting facial expression or gesture recognition to measure visual fatigue is analyzed. Results: Bio-signal and brainwave based methods have problems because they can be degraded by not only visual stimuli but also the other kinds of external stimuli caused by other sense organs. In eye image based methods, using only single feature such as blink frequency or pupil size also has problem because the single feature can be easily degraded by other kinds of emotions. Conclusion: Multi-modal measurement method is required by fusing several features which are extracted from the bio-signal and image. Also, alternative method using facial expression or gesture recognition can be considered. Application: The objective visual fatigue measurement method can be applied into the fields of quantitative and comparative measurement of visual fatigue of next generation display devices in terms of human factor.

The purpose of this study was to get some basic data for health care for working women, especially or hospital nurses. The number of subjects was 796 nurses from one general hospital and four private educational hospitals. The data were collected from February to April, 1988 using the questionnaire "Symptom Table on Fatigue Perception" designed by the Research Committee of Industrial Fatigue in Hygienic Association of Japan Industry. The collected data were analyzed using means and standard deviations for the subjective symptoms of fatigue and each item as an independent variable was analyzed by T-test and ANOVA test. The results are as follows 1) The mean score for degree of fatigue was 1.89 and the degree of fatigue for physical symptoms had highest score of 2.04, the next was psychological symptoms at 1.89, and neuro -sensory symptoms were the lowest at 1.74. Among the fatigue symptoms, the item scored most frequently was "Legs feel heavy" with a mean score of 2.40 and the least frequent item was "My hand and foot trembled" with a mean score of 1.40. 2) With the respect to the general characteristics of subjects, there were statistically significant difference according to age (F=17.039, p=.000), state of marriage(t=5.381, p=.000) presence of children(t=5.134, p=.000), clinical experience (F=16.663, p= .000), present position(F=18.204, p=.000), working place(F=12.598, p=.000), duty time(F=9.068, p=.000), monthly wages(F=7.361, p=.000). satisfaction about the pay and treatment at work(t=-5.511, p=.000), relation the doctors(t=-4.593, p=.000) the doctors(t=-4.593, p=.000)

This paper deals with the correlation between physical fatigue and speech signals. A treadmill task to increase fatigue and a set of subjective questionnaire for rating tiredness were designed. The results from the questionnaire and the collected bio-signals showed that the designed task imposes physical fatigue. The t-test for two-related-samples between the speech signals and fatigue showed that the parameters statistically significant to fatigue are fundamental frequency, first and second formant frequencies, long term average spectral slope, smoothed pitch perturbation quotient, relative average perturbation, pitch perturbation quotient, cepstral peak prominence, and harmonics to noise ratio. According to the experimental results, it is shown that mouth is opened small and voice is changed to be breathy as the physical fatigue accumulates.

Fatigue is a universally common word. The subject has been studied in different disciplines, but the basic concept of the term still remains unidentified. It becomes especially important for the medical communications between nurses and clients. Based on the framework outlined by Walker and Avant (1995), this analysis attempts to clarify and examine the symptoms of fatigue. The attributes of fatigue identified in this paper were exhaustion, weighted psychological burden, shortage in capacity or lack of energy, shortage incapacity(motivation and excitement), and imbalance of energy. Therefore, the definition of fatigue refers to a subjective feeling from various internal or external stresses. The consequences of fatigue bring reduced capacity and imbalance of energy. The symptoms show a homeostatic disability or shortage of capacity (physical, psychological, environmental and physiological factors). A precise understanding of "fatigue" will be utilized in defining the causes and measuring outcomes. Also, it will enhance the effective medical communications with client s and nurses. In conclusion, more work is needed to develop objective measurement and effect ivenursing intervention.

In this study, a wrist protector was manufactured and designed using 3D printing technology to prevent wrist pain when riding a bicycle with a high forward-tilted saddle. The efficiency of the design was analyzed in objective and subjective evaluations. First, seven women in their twenties selected their most preferred design by subjective evaluation from among three 3D wrist protectors. Then electromyography (EMG) was measured and subjective sensations were evaluated while wearing and not wearing the preferred 3D wrist protector as selected by cyclists. Experimental results showed that a wrist-bending angle of 30 degrees was most favored. When the 3D wrist protector was worn, muscle activity was smaller at the flexor carpus radialis position than when the 3D wrist protector was not worn; muscle fatigue was also lower. In the subjective evaluation, the 3D wrist protector was more comfortable than no protector, and wrist fatigue was also lower. In addition, the wrist protector was rated positively for its design suitability, size adequacy, ease of operation, and fit; however, cyclists felt that a little more cushioning was needed.

In order to investigate the complaint rates of subjective fatigue symptoms and study the relationship between them and body type, health awareness in middle school students, we carried out a survey of 1,209 students (654 boy students and 555 girl students) at a middle school in Taejon City by a self-recorded questionnaire. The survey was conducted in June, 1997. The results obtained were as follows: 1. Among complaints of fatigue, "feel like lying down" was the highest, followed by "feel anxious about things", "feel drowsy", "yawning a lot", "eye strain" and "whole body feels tired" in descending order. 2. In the average weighted score of fatigue complaint, dullness and sleepiness (I) was the highest, followed by a difficulty in concentration (II) and bodily projection of fatigue (III) in descending order. Fatigue seems to create mental stress rather than physical burdens. 3. In the classification of body type based on the $R\ddot{o}hrer$ index, the obesity type (145 and above) was 11.0%, standard type (110~144) was 64.7% and leptosomic type (l09 and below) was 24.3%. Comparison between both sexes revealed that the rate of obesity and leptosomic types were significantly higher in boy students than in girl students. 4. In terms body type awareness, the statistics are the following: those who consider themselves to be standard type, 44.3%, slightly obese 24.5%, leptosomic, 23.5% and obese 7.8%. However, the level of obesity awareness was significantly higher in girl students than in boy students. 5. As for health awareness, 36.5% considered themselves healthy, 5.4% generally healthy and 10.1% a little unhealthy, but the level of unhealthy awareness was higher in girl students than in boy students. 6. In the relationship between body type and health awareness, most students thought that they were obese in spite of their standard body type. Also, many students who were obese and leptosomic tended to consider themselves to be a little unhealthy. 7. The more the students were obese or felt unhealthy, the more the average weighted score of fatigue complaints was high.
