Objective: This study was conducted for one-hand users including hemiplegic clients currently using general folding manual wheelchairs, so as to analyze their specific problems and recommend solutions regarding usage. Background: Traditional manual wheelchairs require considerable use and control of both hands for operation, thus adaptations become necessary for individuals with asymmetrical use of hands. Method: Thirty hemiplegic clients who were admitted to rehabilitation and convalescent hospitals participated as subjects. The research tools were general folding manual wheelchairs commonly used by people with impaired gait, and the Wheelchair Skills Tests (WST) WST-M/WCU 4.1 version was adopted as the assessment tool. All participants were asked to fill out questionnaires on demographics and wheelchair usage characteristics. Assessment procedures were performed with currently used manual wheelchairs and with/without the use of foot to control the wheelchair. Results: When the participants drove folding manual wheelchairs without the use of foot, even the lowest failure rate among the WST items tested recorded 96.7%. On the contrary, with the use of foot in maneuvering the wheelchairs, failure rates dropped noticeably and success rate among the WST items tested was as high as 86.7%. Conclusion: These findings imply that the use of one-arm (hand) propellable (drivable) wheelchair can be an active and effective solution in resolving problems for hemiplegic clients using existing manual wheelchairs. As such, the government should provide institutional support to further develop and distribute this device or technology, and promote relative research in tandem. For now, the supply of commercially available device to hemiplegic clients is deemed urgent and also a mechanism to provide the devices and relevant services. Application: This study offers viable solutions for hemiplegic clients who rely on existing manual wheelchairs to increase their mobility and occupational performance.

This study was conducted to analyze the wearing condition on gloves for pilots and to suggest the developments for pilot gloves design. This survey was performed with 99 pilots and the questionnaires included items about discomfort, materials and problems when wearing pilot gloves. The respondents felt uncomfortable on the finger tip, the hollow area of the hand and the end of thumb when they move their hands with the gloves. They replied that the finger length, palm length, and circumference of the fingers did not match well. Also they complained there was severe abrasion in the tip of the thumb, finger tips and the middle of the palm of the gloves. The result of these analyses supports the following suggestions. It is necessary to improve durability by applying the additional materials to the severely worn parts. Punching on the glove materials could improve sweat rate and ventilation, and careful washing should be accompanied to prevent the occurrence of linters and transformation after laundering. And it is needed to prepare an accurate and more diversified size system and to design the gloves fitted to the individual hands. With these in mind, it is required to propose solutions for pilot gloves with reference to the survey results in order to design appropriate pilot gloves in terms of movement, size and material. It was concluded that an analysis of the wearing condition and developments are useful for ergonomics pilot gloves design.

The purpose of this pilot study was to identify the effects of hand moxibustion therapy to decrease pain and relieve coldness of the body in women who had a hysterectomy. The conceptual framework of this study was derived from Ying-Yang, Khi and other corresponding theories. The data were collected from February to May 1997. A Graphic Rating scale was used to measure the degree of pain and Digital Infrared Thermographic Imaging(D.I.T.I) was used to examine the degree of coldness. The subjects were women who resided in Seoul and had a hysterectomy within five years. An experimental group was composed of five women who received moxibustion and a control group was composed of five who did not. The research procedure began with having both the experimental group and control group describe their general characteristics and the degree of pain they perceived. Then, Digital Infrared Thermographic Imaging(D.I.T.I) was conducted. Moxibustion was only given to the experimental group on both hands twice every day for a total of five weeks. Their perception of pain and D.I.T.I were examined weekly. The control group received no therapy. After finishing therapy, the perception of pain and D.I.T.I for both groups were also measured. According to this study, moxibustion therapy resulted in a change of body temperature on the right shoulder joint(p=0.00074), abdomen(p= 0.0047), waist(p=0.0068) and hands(p=0.0317) respectively. Also, the study results showed significant decrease (p=0.0001) in pain over time and significant improvement over body coldness.

The purpose of this study was to examine the dietary habits of boarding high school students in Gangwon based on gender and stress levels. Questionnaires were distributed to 571 boarding high school students and collected from 491 students from June 28 to July 20, 2011. The statistical data analyses were completed using SPSS (ver. 19.0) for the descriptive analysis, independent sample t-test and $X^2$-test. The mean stress score was 23.7 out of 40, and male's stress was significantly higher than female's (p<0.05). The rates of having daily breakfast and dinner were significantly influenced by gender (p<0.01), and the regularity of lunch was significantly different depending on the stress level (p<0.05). Female students consumed less flour based foods (p<0.01), carbonated drinks (p<0.01), juices (p<0.05) and functional drinks (p<0.01) than male students, but male students consumed less cookies and breads (p<0.01). Dietary habits that boarding high school students should improve were an unbalanced diet (38%), too much intake at once (17%) and prejudice against foods (11%), and their primary value in dietary life was preference (33%), followed by staving off hunger (18%) and pleasure (18%). The average level of interest in dietary life was 2.46 (on a Likert-type 3-point scale) and it was significantly higher for female students (2.53) than male (2.40) (p<0.05). About 54% of students washed their hands before a meal when they thought of it, but only 25% of students always scrubbed up. The regularity of breakfast and dinner, frequency of snack intake, dietary habits that need to improve, intrest in dietary life, and washing hands before meals showed significant difference by gender but not by stress levels.

Objective: The purpose of this study was to examine the effect of degrees of freedom on the multi-synergies in two hierarchies of human hand system during force production and releasing tasks. Method: In this study, the constrained movements of the aiming and releasing actions using both hands and fingers during archery-like shooting were implemented as experimental tasks. The participants produced a pulling force holding the customized frame (mimicking an archery bow, with a set of force transducers) and kept it consistently for about 5 seconds, and released fingers as quickly as possible in a self-paced manner within the next 5 seconds. An analytical method based on the uncontrolled manifold hypothesis was used to quantify the stability index (synergy index) in two hierarchies including two hands (upper hierarchy) and individual fingers (lower hierarchy). Results: The results confirmed that the positive synergy pattern showed simultaneously at the upper and lower hierarchies, and the kinetic degrees of freedom were associated with the increment of hierarchical synergy indices and the performance indices. Also, the synergy indices of both hierarchies showed significant positive correlations with the performance accuracy during the task. Conclusion: The results of this study suggest that the human control system actively uses extra degrees of freedom to stabilize task performance variables. Further increasing the degree of freedom at one level of hierarchy induces positive interactions across hierarchical control levels, which in turn positively affects the accuracy and precision of task performance.
