In recent years, public attention to health and wellness issues has increased. The integration of smart fitness hardware and innovative technologies have made the development of smart fitness a trend. The number of fitness applications in the market has surged, and demand for an optimal experience is increasingly high. This study selects Sweatcoin, Home Workout, Six Pack in 30 Days, and Fitness Coach & Diet as research subjects from the top ten global mobile health and fitness apps in 2022 based on download rankings. The research is based on eight gamification elements: motivation, challenge, achievement, relationships, sharing, reward, level, and competition, identified through preliminary studies. We distributed a total of 166 questionnaires to users and collected 163 valid responses for data analysis. The Kano Model was used to study the desires of fitness enthusiasts using fitness apps. To reduce the limitations of the research results, the Better-Worse Method was employed for satisfaction index analysis. Based on the final analysis, we propose suggestions for improvement for the four fitness apps to better meet user needs and create a more attractive and efficient application experience.

Objectives: A mobile health intervention program was provided for employees with overweight and obesity for 12 weeks, and a process evaluation was completed at the end of the program. We investigated participant engagement based on app usage data, and whether engagement was associated with the degree of satisfaction with the program. Methods: The program involved the use of a dietary coaching app and a wearable device for monitoring physical activity and body composition. A total of 235 employees participated in the program. App usage data were collected from a mobile platform, and a questionnaire survey on process evaluation and needs assessment was conducted during the post-test. Results: The engagement level of the participants decreased over time. Participants in their 40s, high school graduates or lower education, and manufacturing workers showed higher engagement than other age groups, college graduates, and office workers, respectively. The overall satisfaction score was 3.6 out of 5. When participants were categorized into three groups according to their engagement level, the upper group was more satisfied than the lower group. A total of 71.5% of participants answered that they wanted to rejoin or recommend the program, and 71.9% answered that the program was helpful in improving their dietary habits. The most helpful components in the program were diet records and a 1:1 chat with the dietary coach from the dietary coaching app. The barriers to improving dietary habits included company dinners, special occasions, lack of time, and eating out. The workplace dietary management programs were recognized as necessary with a need score of 3.9 out of 5. Conclusions: Participants were generally satisfied with the mobile health intervention program, particularly highly engaged participants. Feedback from a dietary coach was an important factor in increasing satisfaction.

The purpose of this study was to determine changes in body composition and blood lipids and to analyze the effects of Danhak exercise for 3 months in older women. For this study, 35 female subjects 60 to 70 years of age were recruited and administered 90 min of Danhak exercise, five times per week for three months by a professional coach. The results of this study were as follows: At baseline, the mean BMI(body mass index) and body fat(%) were 23.9 kg/$(m)^2$ and 32.4$\pm$4.9(%), respectively. The mean WHR(waist-hip ratio) was 0.91$\pm$0.04 and all subjects were determined to be abdominally obese. A significantly lower body fat was observed after 3 months of Danhak exercise(p<0.05). However, there were no significant differences in BMI, WHR or body weight before and after exercise. Danhak exercise also resulted in a decrease in total cholesterol and an increase in HDL(high density lipoprotein, and these differences were significant. Taken together, the results of this study indicate that the effects of Danhak exercise were similar to those of aerobic exercise with respect to improve body fat(%) and blood lipid profiles, which suggests that Danhak is a profitable exercise for individuals aged 60 and over.

Internet gaming disorder (IGD), one of the common subtypes of internet addiction, is now classified in Section 3 of DSM-5 and is increasingly regarded as a growing health concern in many parts of the world. Consequently, many psychotherapeutic and psychopharmacological approaches have been considered and some research regarding therapeutic strategies has been conducted. However, treatment of IGD is in its early stages and therefore is not yet well established. This article reviews multiple therapeutic modalities including our own treatment model for IGD according to clinical and biological effects, thus providing suggestions for standard treatment strategies. The two main streams are psychopharmacological treatment and cognitive-behavior treatment, and the cognitive-behavior approach includes cognitive reconstruction, psychoeducation, and parenting coach. Many other non-pharmacological treatments are also recommended for personalized treatment of IGD.
