Purpose: The purpose of this study was to testify effects of Balance Taping Therapy on the pain and range of motion of the knee joint in the female elderly with degenerative knee arthritis. Method: The research design was one group pretest-posttest design. The data were collected from November 15 to December 25, 2004. The subjects were 23 female elderly with degenerative knee arthritis who were registered at one public health center in Busan. Balance Taping Therapy was conducted twice a week for 5 weeks. The data were analyzed such as the number, percentage, paired t-test, Kolmogorov-Smirnov test using SPSS 10.0 WIN Program. Result: The pain in the female elderly with degenerative knee arthritis significantly decreased from 8.82 to 6.04 after Balance Taping Therapy(t=16.781, p=0.001). The knee flexion joint range of motion in the female elderly with degenerative knee arthritis significantly increased from 119.73 to 123.13 after Balance Taping Therapy (t=-6.003, p=0.001). The knee extention joint range of motion statistically significantly increased from 112.74 to 117.83 after Balance Taping Therapy(t=-8.940, p=0.001). Conclusion: Balance Taping Therapy proved an effective nursing intervention in decreasing pain and increasing the range of motion of the knee joint in the female elderly with degenerative knee arthritis.

This study was conducted to investigate whether mat exercise and field exercise have effectiveness on the balance and gait in older adults. Thirty subjects were participated in this study. And they were all randomly divided into mat exercise and field exercise group. To evaluate the effects of mat and field exercise, subjects were evaluated by using One Leg Stand test which was static balance test, and Berg Balance test which was dynamic balance test. Finally Gait pattern was assessed by using 3-dimensional gait analysis system. The assessment parameters were evaluated before, after 3 weeks, and after 6 weeks treatments. And we received a consent form from all subjects. The results of repeated measures analysis of variance showed that One Leg Stand, Berg Balance, Stride length, Cadence, Velocity were significantly increased after than before exercise in both groups. So we conclude that therapeutic exercise that is mat and field exercise has effectiveness on the balance and gait in older adults.

Background: Recommendations have been proposed for minimum aerobic fitness among firefighters but it is unclear if those criteria relate to performance on the fireground. Less fit individuals fatigue more quickly than fit individuals when working at comparable intensity and may have gait changes, increasing risk of falls. We evaluated the effect of fatigue during a live burn evolution on gait parameters and functional balance comparing them to aerobic fitness levels. Methods: A total of 24 firefighters had gait and balance tested before and after a live burn evolution. Data were stratified by aerobic fitness of greater/less than 14 metabolic equivalents (METs). Results: Analysis of gait cycles measurements before and after the live burn evolution revealed that single leg stance, cycle, and swing time decreased (p < 0.05) but there were no differences in the other measures. There were no differences in time to complete the functional balance test, or errors committed before or after a live burn evolution. When firefighters were sorted by fitness level of 14 METs, there were no differences for errors or time before or after the live burn evolution. Balance data were analyzed using a linear regression. Individuals with lower fitness levels required more time to complete the test. Conclusion: A 14-MET criterion failed to distinguish gait or balance characteristics in this group. However, less fit firefighters did require more time to complete the balance test (p = 0.003). Aerobic fitness alone does not predict gait changes among firefighters following a live burn evolution but does appear to influence functional balance.

The purpose of this study was conducted to investigate the influencing factors on foreign workers's work-life balance and provide guidelines for interventions and strategies to increase work-life balance in foreign workers. This study was a secondary data analysis from the $4^{th}$ Korean Working Conditions Survey(KWCS). The sample included 179 foreign workers. Data were analyzed using SPSS 22 and AMOS 22. As a results, the hypothetical path model was a good fit. In the path analysis, health status, social support, work time, job satisfaction had statistically significant effects on foreign workers's work-life balance and these variables explained 24.9% of work-life balance. These results reveal the predictors of work-life balance in foreign workers. Therefore, we need the active support for work-life balance predictors.

The purpose of this study was investigate the effect of gastrocnemius(GCM) muscle length on the dynamic balance and antero-posterior pressure distribution of foot. Thirty subjects were recruited and each subject was classified with control experimental and control group according to GCM muscle length. The experimental group included subjects with shortness of GCM muscle length, the control group included subjects with normal length of GCM. The dynamic balance and antero-posterior pressure distribution of foot were measured by Biorescue equipment. To evaluate dynamic balance, we collected data of limit of stability in antero-posterior direction. We analyzed the data by using independent t-test. The alpha level was set 0.05. The results showed that the dynamic balance and antero-posterior pressure distribution of foot were significantly different between two groups (p<0.05). This study suggests that the shortness of GCM affects anterior limited of stability in dynamic balance and anterior pressure distribution of foot. Therefore, it is important to maintain optimal GCM muscle length for normal balance ability and prevention of musculoskeletal disease.

A comparative study of acid-base balance has been made between acidemia-induced hyperkalemia and hyperkalemia-induced acidemia. A group of rabbits was infused 0.1 N hydrochloric acid solution and metabolic acidosis was induced. Another group was administered 20 mM potassium chloride solution and hyperkalemia was induced. The third group was infused 0.1 N hydrochloric acid and 20 mM potassium chloride solution, simultaneously. Acid-base data and plasma potassium ion concentration were monitored every thirty minutes in these three groups of rabbits. Following results were obtained: 1 ) Along with the infusion of hydrochloric acid, acute metabolic acidosis was induced in the rabbits. Plasma bicarbonate ion concentration decreased primarily in this group. As a respiratory compensation, there was a tendency of reduction of arterial $Pco_{2}$. The alteration of data became larger along with the amount of administration and the time elapsed. However, hyperkalemia was not so severe compared with the second group. 2) In potassium chloride infused group, plasma potassium ion concentration increased along with the time elapsed and the amount of infusion. And the alteration of acid-base data was parrallel to the level of potassium ion concentration, above all depression of pH was prominent. 3) Above data suggest that when acute metabolic acidosis was induced, exchange of intracellular potassium ion with extracellular hydrogen ion seems significant for the regulation of extracellular acid-base balance. And when hyperkalemia was induced with the infusion of potassium chloride solution, the exchange of intracellular hydrogen ion with extracellular potassium ion also seems significant for the regulation of extracellular potassium balance. 4) In the group of rabbits infused hydrochloric acid and potassium simultaneously, disturbances of acid-base balance and potassium balance were much more severe than two other groups. In these mixed disturbances, the process of compensatory mechanism might be inhibited and one disturbance might aggregate each other. 5) Through above data it has been postulated that in acid-base disturbance potassium balance can be sacrificed as a compensatory mechanism, and vice versa in disturbance of potassium balance. And our data also suggest that hydrogen ion and potassium ion are compensatory pair, one another.

This study aimed to identify differences in the level of work-life balance as well as the effect of independent variables, including family (sharing family work, support for working), organization (culture, support services and systems), and community variables (accessibility to and amount of work-life balance programs), on work-life balance in South Korea, Japan, and the U.K. For these purposes, data were collected from 311, 324, and 322 married, working women (from 30 to 50 years of age) from Korea, Japan, and the U.K., respectively. It was consistently shown that U.K. employees scored higher in work-life balance than Korean and Japanese employees. Compared with Japan and the U.K., Korean participants were significantly lower in terms of work-leisure balance and work-self-development balance. The regression analysis revealed that 'sharing family work with partner' was commonly important and a major factor in all three countries. A 'supportive organizational culture' predicted work-life balance for Korean and Japanese participants, while work-life balance programs had a powerful effect on work-life balance only for U.K. participants. In the case of community variables, there were no significant effects for U.K. participants with regard to work-life balance. In contrast, 'the amount of work-life balance programs offered' was shown to affect the work-life balance of Korean working women, while 'accessibility to the programs' was significantly influential in Japan. We interpret these results according to social, economic, political, and psychological factors.

This study was designed 1) to quantitatively observe changes in static platform and 2) to observe balance performance using vision. Seventy-five subjects participated in the study. Subjects comprised 39 males and 36 females(mean ages=23.8 years) without neurologic and orthopaedic impairments. Static balance was measured with eyes open and closed. Subjects was required to move the cneter of balance curser in a counterclockwise for 30 sec. The effect for the COBx(-) suggests that subjects tended to maintain their weight slightly In the left. The time taken and the accuracy to move the center of balance from target to target was 14 sec, $49.47\%$. The body sway upon reaching the target was 7.3 AP sway and 11.88 LR sway distance. In this study, the data developed could be appropriate to use for sine comparisons when balance training patients with neurologic or orthopaedic impairments.

Purpose: Unilateral strength training effects on contralateral sides have been demonstrated in previous studies for lower extremity exercise, upper extremity exercise, and unilateral surface electrical stimulation. This study was performed to investigate the effects of unilateral ankle training on muscle strength and the balance of contralateral lower extremity in healthy adults. Methods: Thirty healthy subjects were randomized equally to a training or a control group. Those in the training group received unilateral ankle isokinetic strengthening training of the dominant leg (right side) for 4 weeks. Contralateral single-limb balance, including Anterio-Posterior Stability Index (APSI), Medio-Lateral Stability Index (MLSI) and Overall Stability Index (OSI), was assessed before and after intervention. Results: Comparison of pre- and post-test data revealed significant improvements in ipsi- and contralateral ankle strengths, and significant improvement in contralateral single limb balance. Conclusion: These results have practical implications because they demonstrate that unilateral ankle isokinetic exercise improves ankle muscle strength and balance ability of contralateral lower extremity.
