At the dawn of a new digital era, people's way of spending their leisure time and leisure activity preferences changed. Accordingly, Leisure culture is in the midst of change, such as watching movie and performance, enjoy golf etc. Due to its nature as an interactive medium, the digital game offers uniquely different approaches to the leisure activity. Leisure as state of mind is much more subjective in that it considers the individual's perception of an activity. In that regard, we used the digital games for leisure activity. Digital games are powerful environments for fun, including functional nature. For that reason digital leisure culture keep creative evolving. This paper proposes a serious games as a branch of digital games that meaningful digital leisure, and introduced the concept of serious games for a serious purpose other than pure entertainment. Many recent studies have identified the benefits of using serious games in a variety of purposes. Games technology is fun and entertaining for people of all ages. Ultimately, serious games become meaningful and valuable performance tools as the Digital Leisure Culture.

A growing number of people are enjoying sports activity with a rise in national income. In this current, many patients complain of traumatic shoulder dislocation and chronic instability with bony Bankart lesion. Computed tomography arthrography is good diagnostic modality for bony Bankart lesion. It is important to consider the patients' factors such as occupation, sports activity, size of preoperative glenoid bone loss before decision of treatment. As development of arthroscopic treatment, there is no significant difference in the result of bony Bankart repair between arthroscopic surgery and open surgery. However, open surgery should be considered for patients with preoperative glenoid bone loss more than 25% or in need of collision sports activity.

The present study attempted the segmentation of the art gallery visitors on the basis of leisure lifestyles. For this purpose, leisure lifestyle surveys were administered at Korea's three representative art galleries, the National Museum of Modern and Contemporary Art, Seoul Museum of Art, and Seoul Art Center's Hangaram Art Museum. A total of 314 questionnaires were analyzed to identify leisure lifestyle factors. On the basis of the lifestyle factors, a cluster analysis was performed, and then the differences of demographics, museum visiting behaviors, and general cultural consumption among the clusters were examined. The cluster analysis revealed four groups of lifestyles, 'culture and art lovers', 'active homebodies', 'low leisure spenders', and 'omnivorous culture and sports participants'. The four groups revealed the differences in terms of demographics, museum visiting behaviors, and general cultural consumption. On the basis of the findings, the marketing strategies targeting the segmented art gallery markets were discussed.

Knee sleeve has been used for prevention of sport injuries as well as rehabilitation. To investigate prevention of sport injuries of knee sleeve, it is important to evaluate balance associated with proprioception. The aim of this study was to evaluate the effects of a knee sleeve with a pad that stimulate to golgi tendon organ (GTO_PAD) on proprioception and balance ability. Five healthy males were participated for the study. They were asked to reenact target angle with Biodex and perform one leg standing with knee sleeve and knee sleeve with GTO_PAD. There was no significant difference in %Target angle, but the value of %Target angle was higher in subjects wearing knee sleeve with GTO_PAD than only knee sleeve, except for one subject. During one leg standing, time duration was increased in subjects wearing knee sleeve with GTO_PAD. The length of center of pressure in x-axis (COPx) and COP in y-axis (COPy) were decreased when wearing knee sleeve with GTO_PAD (COPx : $162.06{\pm}58.99mm$ in knee sleeve vs. $149.03{\pm}45.30mm$ in knee sleeve with GTO_PAD, COPy : $310.79{\pm}115.89mm$ in knee sleeve, $291.57{\pm}76.53mm$ in knee sleeve with GTO_PAD). There was significant differences in INI_transition, steady, and LAT_transition phase (all, p < 0.05). These findings support that wearing knee sleeve with GTO_PAD might enhance proprioception and balance.

Based on sports known to reduce adolescents' smartphone addiction, this study aims to identify the structural causal relationship between sport commitment and smartphone addiction. First of all, based on prior studies, it was intended to show that adolescents' sport commitment is effective in reducing smartphone addiction through social support and ego-resilience, and that such causal relationships vary significantly depending on gender. To this end, a survey of 605 middle and high school students was conducted, and the structural relationship between the four established latent variables was analyzed by analyzing the structural equation model using the SPSS 25.0 and AMOS 23.0 programs. According to the analysis, adolescents' sport commitment was found to have an adverse effect on smartphone addiction, and social support and ego-resilience in the relationship between the two variables were found to have a mediated effect. In addition, these results showed significant differences in gender. This study expanded the field of smartphone addiction and sports convergence study by revealing the relationship between sport commitment as psychological recognition variable and addiction Unlike previous studies using a participation time, duration, and intensity, and suggested that structural relationships with personal characteristic variables and gender-specific approaches are important. Through this, it is meaningful that it provided basic data for in-depth convergence study in the smartphone addiction and development of gender-specific programs.

The aims of this study were to compare the differences in hemodynamics between cigarette smoking and using heated tobacco products (HTPs) and to determine the acute effects of using HTPs on cardiac autonomic regulation. Another goal was to examine the acute cardiac autonomic responses when using different tobacco sticks in HTPs. Sixteen healthy male smokers completed an open-label, randomized, crossover trial consisting of non-smoking (NS), cigarette smoking, and the use of two different HTPs (IQOS with HEETS; lil SOLID with Fiit). Sub-trials, which included NS, lil SOLID with Fiit, and lil SOLID with HEET, were performed on eight smokers among the total subjects. Hemodynamic variables, such as systolic blood pressure (SBP) and diastolic blood pressure (DBP), and heart rate variability were measured before, during, and 30 minutes after using each tobacco product. Using HTPs resulted in a significant increase in both SBP and DBP, comparable to smoking cigarettes. Cardiac sympathetic activity significantly increased, and cardiac vagal tone (CVT) significantly decreased after acute exposure to HTP aerosol, similar to the effects of cigarette smoke exposure. Furthermore, differences in the withdrawal of CVT were observed when using different tobacco sticks in the same HTPs. The findings of this study indicate that acute exposure to HTP aerosol increases the hemodynamic burden and disrupts cardiac autonomic balance, similar to exposure to cigarette smoke. Moreover, depending on the type of tobacco stick inserted into the HTP device, acute withdrawal of CVT may have been enhanced.

This study examined the effect of VT(Vibration Training) on the symptoms of DOMS (Delayed-Onset Muscle Soreness) before induced by eccentric exercise of the left leg triceps surae. Twenty one healthy adult men and women who had not participated in a regular exercise program for the lower extremities were assigned to one of two experimental groups: vibration training group, Control group. We measured the VAS(Visual Analogue Scale), ankle plantar flexor strength, triceps surae circumference, CK(Creatine Kinase) before and after exercise and 24, 48 and 72 hours after eccentric exercise. After inducing DOMS, VAS showed significant differences between groups at a point of time 48 hours, and showed significant differences within groups in accordance with the time of measurement(p<.05). Plantar flexor strength of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). Triceps surae circumference of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). CK of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). As a result of the study, VT prior to eccentric exercise is effective to inhibit pain. So, this method can be suggested to prevent DOMS in doing an unfamiliar activites.

The purpose of this study is to examine the effects of short-term foresters on brain waves and pulse waves. For this purpose, 484 foresters who visited the natural recreation forest located in Cheongpyeong city, Gyeonggi province, measured the before and after experiences of EEG and pulse waves, and the following results were obtained. First, foresters have been shown to be effective on concentration, brain activity, and brain stress. Second, foresters had positive effects on cardiac health and autonomic health. In other words, when various substances released from the forest come into the body through the respiratory system, it firstly affects the heart activity positively, and it seems to be able to expect various improvements by acting on the emotional side of the brain. Therefore, based on the scientific basis of the forest experience, it is expected that the experience of forests will be widely used as a guide for healthy life by creating conditions for participation by many people. In addition, the mechanism of respiration, heartbeat, and brain interaction is also possible, and various experimental studies on the forest experience in the future are important.
