This study assessed scuba divers' wetsuit selection criteria based on the gender, age and scuba diving commitment level along with identifying currently owned and preferred wetsuit types. Lamb and Kallal's Functional, Expressive, and Aesthetic Consumer Needs (FEA) Model was the conceptual framework used for this study. Scuba diving has seen consistent growth, worldwide, it is necessary to investigate with wetsuit needs of this consumer group. A survey of 302 active scuba divers participated in the study. Total participants included 202 male and 100 female scuba divers. Divers stated fit was the most highly rated criteria with don/doff being most problematic. Female and older divers regarded functional performance criterion greatly(p<.05). Highly committed divers regarded the functional quality (p<.01) and aesthetic/expressive features (p<.05) of the wetsuit as important and owned more wetsuits(p<.01). Gender saw differences in required sizes ranges(p<.001) and style preferences(p<.05). Results suggest gender, age, and commitment levels all impact the wetsuit selection criteria of scuba divers.

Background & Object : Postprandial epigastric fullness is one of common symptoms in functional dyspepsia, but its pathophysiological mechanism has still been unknown. In this study, its association between postprandial epigastric fullness and pyloric valve disturbance was studied through analysis of bowel sounds and electrogastrography. Methods : Bowel sounds and electrogastrography were recorded together for fasting 15 min and postprandial 40 min. Parameters of bowel soundincluding motility index, sound to sound interval, standard deviation of sound to sound interval, sounds per minute, % of bowel sound, sound length, intensity, dominant frequency of sounds, and postprandial / fasting ratio of dominant frequency of sounds were analyzed with a specialized program. By electrogastrography, regularity of slow waves and power ratio were obtained. Results : Significances of bowel sounds appeared in motility index (p=0.046), dominant frequency of fasting (p=0.048), postprandial (p=0.003), and the ratio of postprandial/fasting (p=0.000); those of EGG parameters were shown in postprandial regularity of slow waves (p=0.006) and power ratio (p=0.011). Conclusion : Pyloric valve disturbance was a cause of postprandial epigastric fullness in patients with functional dyspepsia. Analysis of bowel sound might be useful in diagnosing its existence.

Objective: To compare short- and long-term dentoalveolar, skeletal, and rotational changes evaluated by Björk's structural method of superimposition between children with Class II malocclusion treated by functional appliances and untreated matched controls. Methods: Seventy-nine prepubertal or pubertal children (mean age, 11.57 ± 1.40 years) with Class II malocclusion were included. Thirty-four children were treated using an activator with a high-pull headgear (Z-activator), while 28 were treated using an activator without a headgear (E-activator). Seventeen untreated children were included as controls. Lateral cephalograms were obtained before treatment (T1), after functional appliance treatment (T2), and after retention in the postpubertal phase (T3). Changes from T1 to T2 and T1 to T3 were compared between the treated groups and control group using multiple linear regression analysis. Results: Relative to the findings in the control group at T2, the sagittal jaw relationship (subspinale-nasion-pogonion, p < 0.001), maxillary prognathism (sella-nasion-subspinale, p < 0.05), and condylar growth (p < 0.001) exhibited significant improvements in the Z- and E-activator groups, which also showed a significantly increased maxillary incisor retraction (p < 0.001) and decreased overjet (p < 0.001). Only the E-activator group exhibited significant backward rotation of the maxilla at T2 (p < 0.01). The improvements in the sagittal jaw relationship (p < 0.01) and dental relationship (p < 0.001) remained significant at T3. Condylar growth and jaw rotations were not significant at T3. Conclusions: Functional appliance treatment in children with Class II malocclusion can significantly improve the sagittal jaw relationship and dental relationships in the long term.

The purpose of this study was to investigate the effect of multi-functional fabric on EEG and growth hormone (GH) during sleep and quality of sleep with the 9 young female athletes. The subjects participated in separated experimental procedure; sleeping in multi-functional fabric wear (experimental group) and cotton wear (control group) for 450min. During the night (22:00-05:30), we recorded the changes of nocturnal polysomnographic sleep recording and GH were measured every 60min. The results show that there are significant differences in percentage of stage 1, 2 and slow wave sleep (SWS) between two groups(S1, p<.05; S2, SWS, p<.01). The SWS percentage of experimental group is 1.89 times higher than control group. The changes of GH secretion varied depending on two experimental procedures. The peak of GH secretion in experimental group is more than controls by 2.4time (p<.001). The quality of sleep in experimetal group is significantly higher than control (p<.01). These results suggest muti-functional fabric wear is effective in inducing the deep sleep and increasing GH and quality of sleep.

In this paper, I propose the effects of food therapy on subjects' health and happiness. The result has come out that food therapy enhances subjects' multi-dimensional health(medical, functional, self-evaluative) and their happiness. The participants were 230 adults over 30 years old living in Seoul and Gyeonggi district. To examine the effect of food therapy, the study sampled 220 questionnaire out of 230. By the non-equivalent control group design, the health levels were measured in three concepts: medical dimension, functional dimension and self-evaluative dimension. The results are as follows: First, participants who had taken food therapy for 3 months have been enhanced in their subjective and functional health level. Their subjective health enhanced from $2.80{\pm}.44$ to $4.07{\pm}.27$ (p=.000). And their functional health enhanced from $.92{\pm}.07$ to $.94{\pm}.07$(p=.035). Second, participants' happiness has enhanced significantly. Cognitive happiness enhanced from $3.39{\pm}.50$ to $3.84{\pm}.44$(p=.000). And emotional happiness enhanced from $2.76{\pm}.44$ to $3.07{\pm}.34$(p=.000). With this results, in case that people apply food therapy based on Yaksun, they are able to expect their enhancement of health level and happiness. Therefore study shows that Food therapy helps people to pursue their health and happiness improvement and suggest valuable information of a way to enhance quality of life.

Objective: Carpal tunnel syndrome is one of the most common upper extremity compressive nerve disorders in modern people. Various conservative treatments such as taping, exercise, and electrotherapy have been applied to carpal tunnel syndrome and their effectiveness has been proven. This study aims to determine whether home exercise combined with taping is effective for pain and functional disability in patients with carpal tunnel syndrome. Design: Randomized controlled study Methods: 21 patients were recruited and were randomly divided into HEx+T (Home exercise+taping) group (n=10) and HEx (Home exercise) group (n=11). All participants performed Home exercise(tendon and neural gliding exercise) 5 times a week for 6 weeks. Additionally, subject in the HEx group, taping was applied over the wrist and forearm during the training period. Wrist pain was measured by VAS (Visual Analogue Scale). Functional disability was measured using a BCTSQ(The Boston Carpal Tunnel Syndrome Questionnaire). Results: Both the HEx+T group and the HEx group showed a significant improvement in wrist pain(p<0.05), and the HEx+T group showed a more significant decrease in pain than the HEx group(p<0.05). There was a significant improvement in both groups in functional disability (p<0.05), and the HEX+T group showed more improvement than the HEX group(p<0.05). Conclusions: This study suggests that home exercise combined with taping is effective for pain and functional disability in patients with carpal tunnel syndrome.

Objective: This study aimed to investigate the effects of active and passive soft tissue mobilization and active stretching on pain, functional disability, and flexibility in patients with nonspecific low back pain (NS-LBP). Specifically, it compared the effectiveness of these interventions when applied to the hamstring muscles. Design: A randomized controlled trial Methods: A total of 45 participants (mean age: 23.03±3.90 years) with NS-LBP were randomly assigned into three groups: active soft tissue mobilization (ASM) group (n=15), passive soft tissue mobilization (PSM) group (n=15), and hamstring active stretching (AS) group (n=15). The interventions were conducted for 20 minutes, three times a week, for four weeks. Outcome measures included pain assessed by the Numeric Pain Rating Scale (NPRS), functional disability measured by the Oswestry Disability Index (ODI), and flexibility assessed using the Sit and Reach Test and Passive Straight Leg Raise (PSLR) test. Results: The ASM group showed a significant reduction in NPRS scores (p<0.01) and ODI scores (p<0.01) compared to the PSM and AS groups. The ASM group also demonstrated significant improvements in flexibility in both the Sit and Reach Test (p<0.01) and PSLR test (p<0.01) compared to the other groups. Conclusions: Active soft tissue mobilization was more effective than passive soft tissue mobilization and active stretching in reducing pain, improving functional disability, and enhancing flexibility in patients with NS-LBP. These findings suggest that active interventions should be prioritized for managing NS-LBP.

Background: Multifaceted approaches will be needed, such as global synkinesis (GS) achieve functional improvements in the arms of stroke patients from involuntary movements during exercise. Objective: To identify changes in arm GS and muscle activity, functional evaluation and the correlation with variables through action observation training, combined with functional electrical stimulation (FES), thereby verifying the effect on stroke patients. Design: A quasi-experimental study. Methods: The subjects of this study were 20 stroke patients who were divided into two groups: Control group (n=10) and experimental group (n=10). Before the intervention, arm GS and muscle activity were measured using surface electromyography (EMG), and arm function was evaluated using the Fugl-Meyer Assessment (FMA) scale. At the end of the intervention, which lasted 4-wk, arm GS and muscle activity were measured again using the same scale. Results: There was a decrease statistically significant difference in GS during the bending action in experimental group (P<.01). Both groups showed a significant difference increased only in the activity of the anterior deltoid (AD) and biceps brachii (BB) (P<.05). The results of the arm functional assessment revealed a significant difference increase in both groups (P<.05). In the between-group comparison, there was a significant difference decrease in GS during the bending action (P<.05). Only the muscle activity of the AD and BB were significantly increase different (P<.05). There was a significant between-group difference increase in the arm functional assessment (P<.05). There was a positive correlation between GS and muscle activity on the FMA in the control group (r=.678, P<.05). In experimental group, GS during the bending arm action exhibited a negative correlation (r=-.749, P<.05), and the muscle activity of the AD and BB showed a positive correlation (r=.701, P<.05). Furthermore, in experimental group, the activity of the extensor carpi radialis increased, and the activity of the flexor carpi radialis decreased, which exhibited a negative correlation (r=-.708, P<.05). Conclusion: These results suggest that brain plasticity could be more efficiently stimulated by combining surface stimulation in the affected arm of stroke patients.

The study of p53 tumor suppressor protein is one of most important subjects in an environmental toxicology as well as in cancer biology. Generally, p53 has been known to involve the cell cycle regulation and apoptosis by the activation of its target genes such as p21 and bax in a number of cellular stress responses. In addition, associations of p53 with cellular proteins presumably reflect the involvement of p53 in critical cellular processes such as DNA repair. The complex formation of p53 and exogenous proteins such as viral or cellular proteins has been shown in many cases to play important roles in carcinogenic processes against environmental mutagen. Recently, the disruption of p53 protein by oxidative stress has been also reported to have relevance to carcinogenesis. These findings suggested that the maintaining of stability and functional activity of p53 protein was also important aspect to play as a tumor suppressor protein. Therefore, the detection of functional status of p53 proteins might be an effective biomarker for the cancer and human diseases under the environmental toxicologic carcinogen.
