Purpose: The purpose of the study was to develop an emotional self-regulation program for obese children and to examine the program's effectiveness on depression, eating habits, and body mass index. Methods: The emotional self-regulation program was developed from theory-based strategies and a pre-post pilot study was conducted with 46 children (19: intervention, 27: control). The program included 6 weekly group sessions over 2 months. The embedded experimental model of concurrent mixed methods was used to better understand research outcomes by converging both quantitative and qualitative data. Anthropometric measurements and surveys were performed before and after the intervention. Three focus group interviews were conducted with all participants after intervention to explore their experiences. Results: The intervention group displayed decreased depression levels in the quantitative outcomes. The participants also expressed positive outcomes such as improvements in confidence, impulse management, intimacy, happiness, and losing weight. Conclusion: These findings suggest that emotional self-regulation skills are crucial factors for obese children not only to manage their emotional problems but also to control their weight. Further research is needed with a larger sample size and randomized controlled trials.

The aim of this study was to determine the effect of a non-elastic fixation belt on the balance ability and fall prevention in elderly women. Elderly women experience reduced balance ability and an increased risk of falls due to a weakening of the surrounding sacroiliac joint and pelvic muscles during childbirth and menopause. On the other hand, specific studies are still needed. The subjects were allocated randomly to two groups: control (n=20) and experimental (n=20). The experimental group used a non-elastic fixation belt, whereas the control group had no fixation belt. The balance ability and the fall index were measured in all subjects using a balance measurement device, and the low abdominal muscle thickness was determined in the experimental group using ultrasound imaging for the exact application of the non-elastic fixation belt. The following statistical analysis was performed: an independent t-test for the general characteristics of the subjects, $2{\times}2$ analysis of variance with repeated measures for the balance and fall index score, and a paired t-test for the abdominal muscle thickness. The group ${\times}$ time interaction effect showed significant improvement in the General Stability Index (F1,38=47.24, p=0.001), Fourier Harmony Index (F1,38=88.83, p=0.001), Weight Distribution Index (F1,38=50.21, p=0.001), and Fall Index (F1,38=21.59, p=0.001). The thicknesses of the transverse abdominal (p=0.001) and internal oblique (p=0.001) muscles were increased significantly in the experimental group after using the non-elastic fixation belt. Overall, the application of a non-elastic fixation belt could be effective in improving the balance ability and fall prevention in elderly women.

The present study is to determine the effect of lumbosacral stabilization exercise program on back pain disorder and gait velocity of patients with chronic low back pain. The subject was extracted randomly from 34 patients with chronic low back pain and divided into 18 patients of experimental group and 16 patients of control group. Before the experiment, the Oswestry disability index examination and analysis of gait speed were performed. Then, a conventional interventional therapy of physiotherapy was performed with the experimental group along with the lumbosacral stabilization exercise while only the conventional interventional therapy was done to the control group. Both groups did the above treatment every 30 minutes, four times a week for four weeks. Then, post-examination was carried out followed by comparing the back pain disorder index and gait velocity before and after the experiment for the two groups. The back pain disorder index showed that both experimental and control groups had significant difference within the group (p>.01)(p>.05), With regard to the gait velocity, both experimental and control groups had a significant difference within the experimental group and between the groups (p>.001)(p>.05).

Purpose This study re-analyzes Jung 2012's data using the time interval based analysis to examine if the process of idea generation is in good currency throughout the ideation sessions. In this way, the relationship between extraversion-introversion personality trait and ideation performance in the context of computer-mediated idea generation can be better understood. Design/methodology/approach A $2{\times}4$ factorial design was used, crossing personality differences (extraversion and introversion) with the degree of stimuli (0, 20, 40, and 80 high-quality ideas). Participants were randomly assigned to one of eight treatment conditions. The group simulator is used to measure individual level performance. The number of unique ideas generated by individuals and the exact time stamp when each idea was submitted were analyzed to compare performances. Findings The results show that introverts' performances significantly drops after about the middle stage of the ideation session, whereas extraverts do not seem to feel time constraints throughout the ideation session, resulting in superior divergent thinking, which is a major key to understand creative productivity in the problem-solving process. Since extraverts tend to yield a larger pool of ideas, another interpretation is that group composition with extraverts compared with introverts may create a logically larger group, which is important to improve the performance of idea generation group.
