  • On the positive real number, we obtain the Hyers-Ulam stability and a stability in the sense of R. Ger for the generalized beta function g(x+p,y+q) = ${\varphi}(x,y)g(x,y)$ in the following settings: $$\mid$g(x+p,y+q)-{\varphi}(x,y)g(x,y)$\mid${\leq}{\delta}$ and $$\mid$\frac{g(x+p,y+q)}{\varphi(x,y)g(x,y)}-1$\mid${\leq}{\psi}(x,y). As a consequence we obtain stability theorems for the gamma functional equation and the beta functional equation.

  • Purpose: The purpose of this study was to determine the effects of functional insole application using a hallux point on dynamic balance. Methods: Twenty-nine participated in this study. The experiment investigated changes in dynamic balance with the use of a functional insole that emphasized the hallux point. After explaining the experiment to the subjects, the Y-balance test was conducted to measure dynamic balance before the insole was applied. The test was then repeated after the functional insole with the hallux point was. Paired t-tests were used to analyze the statistical differences before and after the application of the functional insole with the hallux point. Results: The functional insole that emphasizes the hallux point significantly increased the distance in the anterior (p<0.05), posteromedial (p<0.05), posterolateral (p<0.05) directions as well as the composite score measured by the Y-balance test compared to before the insole application. Conclusion: The use of a functional insole that emphasizes the hallux point can help the foot pronate during dynamic balance, thereby improving balance through the control of the sole.

  • We report the first spectroscopic evidence of the jet-cooled p-chloro-${\alpha}$-methylbenzyl radical. The visible vibronic emission spectrum was recorded from the corona discharge of precursor p-chloro-ethylbenzene seeded in a large amount of inert carrier gas helium using a pinhole-type glass nozzle coupled with a technique of corona excited supersonic expansion. From the comparison with the vibronic spectrum of the p-chlorobenzyl radical, we identified the evidence of formation of the jet-cooled p-chloro-${\alpha}$-methylbenzyl radical in the corona discharge of precursor p-chloro-ethylbenzene.

  • Objectives The purpose of this study is to establish relationship between allergic diseases and functional gastrointestinal disorders in children and adolescents using objective criteria and questionnaires. Methods This study surveyed 237 children and adolescents who visited the department of Pediatrics of ${\bigcirc}{\bigcirc}$ Korean Medicine Hospital from September 23rd, 2013 to December 26th, 2013. The Korean version of International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire and the Korean-translated Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III (QPGS-Rome III) were used. We analyzed the data by using PASW Statistics 18.0 with Chi-square test, Fisher's exact test and Linear by linear association. Results There was no significant difference between prevalence of allergic diseases and functional gastrointestinal disorders. Also, there was no strong relationship between the number of allergic diseases and the functional gastrointestinal disorders. However, some parts showed significant relationships - such as asthma symptoms ever and belch; asthma symptoms last 12 months and belch; allergic rhinitis diagnosis ever and belly aches and abdominal pain around and below the belly button; allergic rhinitis treatment last 12 months and belly aches and abdominal pain around and below the belly button; and atopic dermatitis diagnosis ever and irritable bowel syndrome (respectively; p=0.046, p=0.008, p=0.004, p=0.029, p=0.035). And as the number of allergic diseases increases, the prevalence of functional gastrointestinal disorders are 19.4%, 31.3%, 41.7%, 31.0% respectively. Conclusions Although there was no significant relationship between allergic diseases and functional gastrointestinal disorders, some gastrointestinal symptoms were related to allergic diseases.

  • This Research is an attempt to find out what effects the resistance exercise program has on the rheumatoid arthritis patient's functional disability and biochemical parameters. The research took place from June to November 1996, and the target included an experimental group of 25 cases of rheumatoid arthritis and a control group of 26 cases of rheumatoid arthritis taken from the Anam Medical Center at Korea University. The resistance exercise program was executed on these patients five times a week during a period of eight weeks. Before and after the experiments, measurements of functional disability score, ESR, CRP, self-efficacy, and family support were taken and closely analysed. The results of this analysis are as follows : 1. After the experiment, the experimental group had less functional disabilities compared to the control group(t=9.11, P=0.0017). 2. After the experiment, the ESR of both the experimental and the control groups decrease, but there was not notable difference between the two groups(t=0.07, P=0.9546). 3. After the experiment, the CRP of both the experimental and the control groups decreased, with no significant different between them(t=0.53, P=0.6022). 4. After the experiment, the self-efficacy of the experimental group increased significantly compared to the control group(t=3.15, P=0.0042), but the self-efficacy had no effect on the actual practice of the program. 5. After the experiment, the family support of the experimental group was higher than of the control group(t=6.33, P=0.0013), but again the family support had no effect on the actual practice of the program. Judging from the results of these experiments, the resistance exercise program not only diminishes rheumatoid arthritis patients' functional disabilities, but also has a great influence on increasing their self-efficacy and family support. Concluding, in diminishing the functional disabilities of rheumatoid arthritis, the resistance exercise program would be appropriate nursing intervention.

  • Purpose: The aim of this study was to investigate the relationship between a functional evaluation model and the Fugl-Meyer assessment (FMA) scale in evaluating the upper extremities of stroke patients Methods: Thirty-eight stroke patients were evaluated using the FMA and performed reaching and grasping motions using a three-dimensional motion analysis (Qquas 1 series, Qualisys AB, Sweden). The participants sat on a chair with a backrest. The position of the cup was located at a distance of 80% to the front arm length. The markers were attached to the sternum, acromion, elbow lateral epicondyle, ulnar styloid process, three metacarpal heads, and the distal phalanges of the thumb and index finger. The variables of the correlation between the functional evaluation model and the FMA scale were analyzed. Multiple regression (stepwise) was used to investigate the effect of the kinematic variables. Results: A significant negative correlation was found between the movement time (p < 0.05), movement unit (p < 0.05), and trunk displacement values (p < 0.05) in the FMA total scores, while a positive correlation was found between the peak velocity (p < 0.05) and maximum grip aperture values (p < 0.05). As a result of the multiple regression analysis, the most significant factor was the movement unit, followed by the general movement assessment and trunk displacement. The explained FMA total score value was 62%. Conclusion: This study presents a new functional evaluation model for assessing the reaching and grasping ability of stroke patients. The factors of the proposed functional evaluation model showed significant correlations with the FMA scale scores and confirmed that the new functional evaluation model explained the FMA by 67%. This suggests a new functional evaluation model for reaching and grasping stroke patients.
