Purpose: This study examined the effects of self-volar gliding combined with a strap and wrist distraction on pain and the active and passive wrist extension range of motion (ROM) in subjects with dorsal wrist pain during partial weight bearing of the hand. Methods: Thirty subjects (14 males and 16 females) with dorsal wrist pain during partial weight bearing through the hand participated in this study. The two different self-volar gliding techniques were performed for each group. Self-volar gliding using a strap (SVGS) and SVGS and wrist distraction (SVGSD) were performed five times for one week for each group. The active and passive ROM of wrist extension and the peak pressure pushed by the hand at pain (PPHP) were measured. An independent t-test was used to compare the improvements of these elements between the two different self-volar gliding techniques. The level of statistical significance was at ${\alpha}=0.05$. Results: The active and passive ROM of wrist extension and PPHP were greater in both self-volar gliding groups after the one week intervention. On the other hand, these parameters were greater in the SVGSD group than in the SVGS group (p<0.05) Conclusion: SVGSD is recommended to improve the active and passive ROM of wrist extension and PPHP in subjects with dorsal wrist pain during partial weight bearing of the hand.

PURPOSE: This study compared the immediate effect of a passive mobilization of upper cervical spine (Kaltenborn's joint mobilization) and an active upper cervical stretching (Olaf's Auto-stretching) on patients with neck pain and ROM. METHODS: Twenty-three subjects were randomized selected in the passive group (Kaltenborn's joint mobilization) included twelve subjects and the active group (Olaf's Auto-stretching) included eleven subjects. VAS (Visual Analogue Scale) was measured before and after neck rotation performance. DUALER IQ PRO (JTECH Medical, U.S.A.) was used to measure the neck ROM. Mean value of double measurement was used before performance and after performance. SPSS version 18 was used to compare values independent t-test and paired t-test were used to compare pain and ROM. RESULTS: There are significant difference in the pain and the ROM in both of two group (p<.05). But there are no significant difference pain and ROM between two groups. CONCLUSION: Both of the passive mobilization of upper cervical spine and the active upper cervical stretching are effected on symptom improvement of patients with neck pain reduction and ROM increasing. Especially active upper cervical stretching is more economical, because it has similar effects with the passive mobilization, help to maintain the treatment effect of therapist by themselves and can help to save medical expenses of patients.

Background: It has been argued that changes in muscle activity in the upper trapezius and serratus anterior may or may not cause shoulder joint pain and dysfunction. Objective: To investigate the effects of active vibration exercise on muscle activity regarding scapular stabilization using a flexi-bar. Design: A randomized controlled trial. Methods: A total of 24 subjects were randomly assigned to a flexi-bar group with active vibration and general stick group with non-active vibration. Both groups performed the same four action programs for 6 weeks, three times a week for 30 minutes at a time. The upper trapezius muscle, middle trapezius muscle, lower trapezius muscle and serratus anterior muscle of the dominant side was measured by electromyography before and after the 6 weeks of exercise. The independent t-test and paired t-test were used to analyze data. Results: There was a significant difference between groups in upper trapezius muscle and serratus anterior muscle activity after exercise (P<.05). Also, there was a significant difference in upper trapezius muscle and serratus anterior muscle activity before and after exercise in the flexi-bar group (P<.05). Conclusion: This study demonstrates that active vibration exercise using a flexi-Bar contribute to reduce the activity of the upper trapezius muscle and promote the activity of the serratus anterior muscle.

Direct Power Control technique has become popular in the grid connected Voltage Source Converter (VSC) applications due to its simplicity, direct voltage vector selection and improved dynamic performance. In this paper, a direct method to determine the effect of voltage vector on the instantaneous active and reactive power variations is developed. An alternative Look Up Table is proposed which minimizes the commutations in the converter and results in minimum reactive power variation. The application of suggested table is established for Shunt Active Power Filter (SAPF) application. The Predictive Direct Power Control method, which minimizes apparent power variation, is further investigated to reduce commutations in converters. Both the methods are validated using 2 kVA laboratory prototype of Shunt Active Power Filters (SAPF).

Objectives : Physical activity is known as beneficial to mental health like decreasing depression and stress. In this study, we tried to find out the relationship between body composition, stress, depression, and self-esteem with physical activity level. Methods : International Physical Activity Questionnaire(IPAQ)-short form, SRRS(Social readjustment rating scale), SRI(Stress response index), and BDI(Beck's depression index), SES(Self-esteem scale) were given to peri-menopausal women aged 45-55 and BMI$\geq$23kg/m2. They were given written consent and this study is performed under the permission of institutional review board of Kyung Hee East-west Neo Medical Center. Results : The mean of physical activity of total subjects was 2406MET-min/week(n=42). The physical activity of overweight(23kg/m2$\leq$BMI<25kg/m2) and obese(BMI$\geq$25kg/m2) permimenopausal women was 1428MET-min/week and 2970MET-min/week(p<0.05) respectively. When three levels of physical activity pattern(inactive, minimally active, and HEPA(Health-enhancing physical activity) active) was analyzed, all of them were heavily relied on the activity intensities of walking. The scores of BDI, SRRS, and SRI were lower and that of SES were higher in HEPA active group, not showing statical significance. Anger(subscale of SRI) measures were lower and SES measures were higher in HEPA active group than others among overweight women(p<0.05). Conclusions : The level of physical activity of peri-menopausal women was on the average, but the vigorous activity is thought to be necessary. The HEPA active group showed lower depression, stress and higher self-esteem than minimally active and inactive group.

The purpose of this study was to investigate the impact of lifestyle on the perceived value of children in university students. Questionnaires were distributed to 467 university students with questions covering topics including general personal information and characteristics, lifestyle type, and value of children. First, a cluster analysis based on lifestyle showed that the subjects could be categorized into three groups: negative-leisure types, active-achievement types, and affirmative-fidelity types. The negative-leisure type was highly leisure-oriented and showed a negative self-value; the active-achievement type showed a perspective that valued personal and occupational self-development and a high level of labor-oriented value; and the affirmative-fidelity type favored materialism, seeking occupational aptitude and worth and showing a positive self-value. Second, an investigation of the impact of these three lifestyle types on the students' value of children revealed that the active-achievement type group had high level of belief in the necessity of childbirth, the affirmative-fidelity type group highly valued fulfilling an active parent role, and the active-achievement type group were inclined to delay childbirth. Further, the negative-leisure type group wanted the lowest number of children, while the affirmative-fidelity type group wanted the highest number of children. This study reveals that university students' lifestyle does have an effect on their value of children. It is therefore proposed that a value-focused population education for increasing fertility should relate not only to individuals' value of children but also to their broader lifestyle.

Background: Compared with normal people, stroke patients have decreased voluntary craniocervical motion, which affects their balance. Objects: This study was conducted in order to examine the effects of active craniocervical movement training using a cognitive game on stroke patient's cervical movement control ability, balance, and functional mobility. Methods: The subject of this study were 29chronic stroke patients who were randomly allocated to either an experimental, cognitive game group (n = 15), or control group (n = 14), to which only neuro-developmental treatment (NDT) was applied. The intervention was conducted 5 times per week, 30 minutes per each time, for a total of 4 weeks. Active angle reproduction test, static stability test, limits of stability test, and Time up and Go (TUG) test, respectively, were carried out in order to evaluate cervical movement control ability, static balance, dynamic balance, and functional mobility. Paired t-test was used in order to compare differences between prior to after the intervention, along with an independent-test in order to compare prior to and after-intervention differences between the two groups. Results: After the craniocervical training with a body-driven cognitive game, the experimental group showed significant differences in flexion, extension, and lateral flexion on the affected side, and rotation on the affected side in the active angle reproduction test. The experimental group indicated significant differences in sway length both with eyes-open and with eyesclosed in the static stability test and in limits of stability test and TUG test. The control group to which NDT was applied had significant differences in flexion in the active angle reproduction test and in limits of stability test and TUG test. Conclusion: The above results mean that craniocervical training using a body-driven cognitive game positively influences stroke patient's cervical movement control ability and as a result their balance and functional mobility.

This study was examined whether the experiential marketing factors proposed by Bernd Schmitt were applicable to the consumer behavior of active seniors. The study was analyzed the influence of SEMs have on value perception of brand and attitude formation as well as the behavioral intentions of active senior consumers and whether this effect differed between the level of commitment. For empirical analysis, frequency analysis, EFA, reliability, CFA, SEM, and multiple-group comparison analysis were performed. The results showed that sense and feel factor did not have a significant influence on the value perception of brand, while think factor had a positive effect on the value perception of brand. Act factor did not affect the value perception of brand; on the other hand, relate factor had a significant effect on the value perception of brand. The result of structural equation modeling also revealed that the value perception of brand had a positive influence on attitude formation and behavioral intentions. The result of multiple-group comparison analysis confirmed that the influence of act factor on value perception of brand differed according to the level of commitment, but the positive influence of act factor on value perception of brand was limited to the high-level of commitment group. As a result of the influence relate factor had on the value perception of brand, differences existed between the two groups, and the low-level of commitment group had a greater influence than the high-level of commitment group. So it will be effective for active senior consumers to form fashion communities and let them participate in to enhance positive consumer behavior toward fashion brands.
