The purpose of this study is to identify consumers' needs and purchase intention of high-functional sportswear according to sports participation motivations. Internet survey was done for data collection and the subjects were 300 consumers in their 20-39's who participated in sport activities at least once a week. Factors of sport participation motivations were ostentation, social interaction, self development, mental health, and physical health. Consumers were segmented into the motivation retard group, the multi-purpose pursuit group, the health pursuit group, and the extrinsic motivation pursuit group. And factors of consumers' needs for high-functional sportswear were practicality and comfort function, body protection and physical function, and skin protection and health function. The multi-purpose pursuit group showed strong needs for active and comfort, body protection and physical function, and skin protection and health function but the motivation retard group showed the lowest needs for high functional sportswear. Purchase experiences of high-functional sportswear, accomplishment, and duration period of sport activity affected positively on the purchase intention of high-functional sportswear.

This study aims to address the effect of interferential current therapy and thereby to provide basic resources to physical therapies for internal medicine by identifying symptoms for functional dyspepsia and serum gastrin level that shows gastric motility. Following results were obtained by performing interferential current therapy to 16 subjects composed of 8 for functional dyspepsia group and 8 for control group for 20 minutes a day, 3 days a week, for 6 weeks. In control group, serum gastrin level was significantly( p<.01), lowered after the therapy whereas there was no significant difference observed in all questions from questionnaire for symptoms of functional dyspepsia between before and after the therapy. In functional dyspepsia group, serum gastrin level was significantly(p<.01), lowered after the therapy and there was also significant(p<.01) reduction in every question from questionnaire for symptoms of functional dyspepsia between before and after the therapy. There was more significant decrease in serum gastrin level and reduction in questionnaire for symptoms of functional dyspepsia in the functional dyspepsia group compared to the control group(p<.01). This study confirms the interferential current therapy as an effective therapeutic method for internal diseases including functional dyspepsia since it not only improves the symptoms of functional dyspepsia but also allows the gastric motility close to normal.

Purpose : This study was to identify the effects of Mobilization with Movement combined with exercise (EMWM) on acromio-humeral distance (AHD), range of motion (ROM), pain intensity, and functional performance in patients with impingement syndrome of the shoulder. Methods : The subjects were 40 patients diagnosed with impingement syndrome of the shoulder. Twenty subjects are randomly assigned to each 2 different groups; Group 1. (exercise group), Group 2. (EMWM group). Three weekly interventions were given for 4 weeks. The main outcome measures were ultrasound, goniometer, visual analogue scale (VAS), and Korean Constant shoulder score (K-CSS). The ultrasound (AHD), ROM (flexion, abduction), pain intensity (for shoulder flexion) and functional performance (K-CSS) were compared between the groups. Results : The AHD was significantly increased in Group 2 compared to Groups 1. No significant difference was observed between the groups in the range of abduction of the shoulder, but the range of flexion was significantly increased in Group 2 compared to Groups 1. Pain intensity was significantly lower in Group 2 than in Group 1, and functional performance was significantly increased in Group 2 compared to Group 1. Conclusion : An intervention that combined mobilization with movement with exercise was more effective than exercise alone for rapid recovery from shoulder injury and improvement in functional performance.

In this paper, we study two functional equations with two unknown functions from an Abelian group into a commutative ring without zero divisors. The two equations are generalizations of Swiatak's functional equations with an involution. We determine the general solutions of the two functional equations and the properties of the general solutions of the two functional equations under three different hypotheses, respectively. For one of the functional equations, we establish the Hyers-Ulam stability in the case that the unknown functions are complex valued.

Room temperature powder spray in vacuum process, so called Aerosol deposition (AD) is a room temperature (RT) process to fabricate thick and dense ceramic films, based on collision of solid ceramic particles. This technique can provide crack-free dense thin and thick films with thicknesses ranging from sub micrometer to several hundred micrometers with very fast deposition rates at RT. In addition, this technique is using solid particles to form the ceramic films at RT, thus there is few limitation of the substrate and easy to control the compositions of the films. In this article, we review the progress made in synthesis of piezoelectric thin/thick films, multi-layer structures, NTC thermistor thin/thick films, oxide electrode thin films for actuators or sensor applications by AD at Korea Institute of Materials Science (KIMS) during the last 4 years.

Objective : The sensation of dysphagia, heartburn, globus hystericus, and functional dyspepsia are common symptoms of the functional upper gut disorders. This study was designed to investigate quantity of perceived stress, depression, and anxiety in the patients with functional upper gut symptoms whose esopahgeal manometry(EM) and gatroesophageal reflux (GERT) test were normal. Methods : A total of 38 patients who complained of the symptoms had been tested with 24-hour ambulatory EM and conventional GERT in our gastrointestinal clinic. Thirty patients whose tests had been normal(patients group) were assessed with Symptom Checklist-90-Revision(SCL-90-R), Beck Depression Inventory(BDI), and Spielberger Stait-Trait Anxiety Inventory(STAI) and compared with 30 patients(control group) without functional upper gut symtpoms in the hepatobiliary clinic. The two groups were also assessed by quantity of perceived stress during the last year through self-report. Results: 1) These patients tended to be predominently female, older, and possessed a lower education than control group. 79% of 38 patients who had been tested were normal. 2) Compared to the control group, the patients had significantly higher mean scores on four subscales(somatization, depression, anxiety, and positive symptom distress index). 3) The patient group had significantly more perceived stress than the control group. 4) The patients group had significantly higher levels of depression than the control gorup, but there was not any significant difference in the STAI. 5) There were significant positive correlations between the BDI score and the STAI-trait, the STAI-stait and the STAI-trait, the quantity of perceived stress and the STAI-trait. Conlusion : The patients with functional upper gut symptoms displayed more, psychological distress, sornatization, anxiety, and deperssion. Among them, patients had higer depression than control group. Functional upper gut symtoms could be more appropriately viewed as somatic symptoms of depression. These findings suggest that such patients need to have psychiatric intervention and treatment.
