Background and Purpose: Stroke in young adults is relatively uncommon. Only 3.7-14.4% of all strokes occur in patients aged 15-45 years. Stroke in young adults has more various and diverse possible causes than stroke in the elderly. We studied to gain further insight into both pathogenic and etiologic determinants in young adults with stroke. Methods : We retrospectively reviewed the medical records of 230 young patients aged 15-45 years who were admitted to the 2nd internal medicine department of Kyung Hee Oriental Medical Center with a diagnosis of stroke between May 1995 and May 1999. We analysed clinical features and diagnostic tests, such as brain imaging, cerebral angiography, echocardiography, 24 hours holter monitoring and other laboratory tests. Results : 1. Of 230 young patients with stroke aged 15-45 years(176 males(76.5%) and 54 females(23.5%)), 140 patients(60.9%) showed ischemic stroke and 90 patients(39.1 %) showed hemorragic stroke. 2. The most prevalent age group was from 40 to 45 years with 142 patients(61.7%) 3. The most frequent site of 140 ischemic stroke was MCA territory in 93 cases(66.4%) and Multiple, VA territory, PCA territory, ACA territory in order of frequency. 4. The most frequent site of 90 hemorrhagic stroke was basal galglia hemorrhage 57 cases(63.3%) and subcortical 13 cases(14.5%), pons, thalmus, subarachnoid, cerebellum in order of frequency. 5. The causes of hemorrhagic stroke were hypertension 49 cases(54.5%), arteriovenous malformation 7 cases(7.8%), ruptured aneurysm 4 cases(4.5%), angioma 3 cases(3.3%). 6. The risk factors of ischemic stroke were smoking, alcohol drinking, hyperlipidemia, hypertension, obesity, heart disease, history of CVA, diabetes mellitus, in order of frequency. 7. The comparison of risk factors between ischemic and hemorrhagic stroke: hypertension was prevalent in hemorrhagic stroke, heart disease and history of CVA were prevalent in ischemic stroke. Conclusions: From the above results, we found that stroke in young adults had various possible causes. Young adults with stroke deserve an extensive but tailored evaluation which include angiography and echocardiography for diagnosis.

Purpose: Most research on risky drinking among adults in Korea has focused on problem drinking and high-risk drinking. This paper examines the nature of heavy episodic drinking_(HED) among adults and seeks to identify the risk factors for HED by analyzing differences by gender and age. Method: Participants were 3,886 adults aged 19-64 years from the database of the fifth Korean National Health and Nutritional Examination Survey (KNHANES-V, 2010). Data were analyzed by conducting the Rao_Scott chi-square test, an ANCOVA, and logistic analysis with SAS 9.2. Results: Individuals between 19 and 29 years of age had the highest HED among all age groups. Individuals between 40 and 49 (male adults) and those between 30 and 39 (female adults) showed HED associated with stress, suicidal ideation, smoking, and other health behavior-related variables. Risk factors that affected HED in male adults were age, educational status, and current smoking, while for female adults, the factors were age, educational status, employment, marital status, and current smoking. Conclusions: It is necessary to develop appropriate intervention programs that abate negative emotions and lessen the risk of HED in adults with consideration to gender and age differences.

Purpose: This study investigated the influence of attention-demanding tasks on gait and measured differences in the temporal, spatial and kinematic characteristics between young healthy adults and elderly healthy adults. Methods: We recruited 16 healthy young adults and 15 healthy elderly adults in this study. All participants performed two cognitive tasks: a subtraction dual-task (SDT) and working memory dual-task (WMDT) during gait plus one normal gait. Using the LEGSys+ system, knee and hip-joint kinematic data during stance and swing phase and spatiotemporal parameter data were assessed in this study. Results: In the elderly adult group, attention-demanding tasks with gait showed a significant decrease in hip-joint motion during the stance phase, compared to the normal gait. Step length, stride length and stride velocity of the elderly adult group were significantly decreased in WMDT gait compared to normal gait (p<0.05). In the young adult group, kinematic data did not show any significant difference. However, stride velocity and cadence during SDT and WMDT gaits were significantly decreased compared to those of normal gait (p<0.05). Conclusion: We determined that attention-demanding tasks during gait in elderly adults can induce decreased hip-joint motion during stance phase and decreased gait speed and stride length to maintain balance and prevent risk of falling. We believe that understanding the changes during gait in older ages, particularly during attention-demanding tasks, would be helpful for intervention strategies and improved risk assessment.

Purpose: We aimed to analyze the reliability of the test for choice stepping reaction time (CSRT) under an unstable surface and determine whether there were differences in CSRT between support surface conditions (stable vs. unstable conditions) and between age groups (young adults vs. community-dwelling older adults). Methods: Twenty healthy community-dwelling older adults and twenty young adults performed the stepping task under an unstable condition over two visits. The mean of the two trials measured for each visit was used for the analysis. The test-retest reliability was analyzed using intra-class correlation coefficient (ICC) with a 95% confidence interval, standard error of measurement (SEM), and minimal detectable change (MDC). Differences in CSRT between support surface conditions and age groups were analyzed using the independent t-test with Bonferroni correction. Results: Excellent consistency was observed for ICC >0.90 in both groups. Moreover, the SEM and MDC values of the CSRT in older and young adults were 0.03 and 0.09 and 0.01 and 0.04, respectively. There was a significant difference in the CSRT between the age groups under stable (p<0.001) and unstable conditions (p<0.001). Conclusion: The findings demonstrated that the test for CSRT under an unstable condition had reliable results in both groups. Although older adults demonstrated longer reaction times than younger adults in all surface conditions, increasing the balance control demand by implementing a choice stepping task concomitant with a balance task had no influence on the reaction time in both age groups.

Purpose : The purpose of this study was to investigate characteristics of the muscle activities during level walking and stairs ascending in young adults. Methods : Fifteen young adult were recruited this study. Muscle activity (BIOPAC System Inc., Santa Barbara, U.SA). Statistical analysis was difference between level and stair walking. Results : In stance phase, muscle activity of low extremity generally more increased during ramp ascent both young adults. In swing phase, muscle activity of low extremity generally more increased during stairs ascent in young adults. Conclusion : These results indicate that stair and ramp ascent is more difficult task than level walking in young adults. Muscle activity was more changed at ramp ascent. In the future, we suggest that studies of stair and ramp gait pattern regarding ambulatory patient with disabilities be further studied and an appropriate stairs and ramp inclination will be indicated.

Purpose: The study aimed to identify the effects of sleep hygiene (use of caffeine, alcohol, night eating syndrome, stress, and coping styles), social network, and smartphone-related factors on quality of sleep in young adults. Methods: This was a descriptive research design. Participants completed a questionnaire on evidence-based variables including caffeine intake, alcohol consumption, social network, night eating syndrome, stress, coping styles, and smartphone-related factors. Stepwise multiple regression was used for data analysis to identify factors that influenced the participants' quality of sleep. This study included 288 young adults in South Korea. Results: This study identified the factors affecting quality of sleep in young adults. Their average weekly sleep duration was 6.86 hours with low sleep quality, indicated by a score of 59.34 points (range 17-100). The predictors of sleep quality were sleep mood, sub-items of night eating syndrome, effects of pain over the last four weeks, and social networks, which explained 33% of the variance. Conclusion: Sleep-induced diseases in young adults could be prevented by identifying sleep mood, pain, and social networks, which is important for health and using them as a basis for intervention.

Digital therapy using extended reality (XR) holds great promise for addressing the mental health needs of adolescents and young adults. This study addresses a notable research gap in South Korea by systematically reviewing XR-based digital therapy for the mental health of South Korean adolescents and young adults. We analyzed 26 studies encompassing various aspects, including study type, publication date, research field, research methodology, data sources, program types, program content, sample characteristics, target population, assessment tools, and program effectiveness. Notably, 46.15% of the studies employed an experimental design, whereas over 53% utilized non-experimental approaches. Experimental studies lacked a genuine design, standardized questionnaires, and control variables. Similarly, non-experimental studies failed to report specific literature selection criteria. Consequently, future studies should adopt rigorous methodologies to enhance reliability and validity. Moreover, over 85% of the 26 studies focused solely on virtual reality and did not incorporate augmented or mixed reality. This study identifies the limitations of the previous research. These findings emphasize the need for structured investigations to advance the development of XR-based digital therapy to promote mental health in adolescents and young adults in South Korea.

Purpose: The purpose of this study was to identify changes in physical activity, sleep quality, and quality of life (QOL) during COVID-19 in adults by age group. Methods: An online survey was conducted on a total of 160 participants who were divided into three groups by age; young adults, middle-aged adults, and old adults. The participants responded to the self-reported assessment of the impact of social distancing during COVID-19, International Physical Activity Questionnaire (IPAQ), Pittsburgh Sleep Quality Index (PSQI), and Short Form-36 Health Survey (SF36). Descriptive statistics, analysis of variance, and Pearson's correlation were used for data analysis. Results: There were significant differences between the three age groups in physical activity (p<0.05) and PSQI (p<0.01) and a post hoc analysis showed that the young adults' group had significantly higher physical activity than the old adults' group, while the old adults' group had significantly lower scores of PSQI (better sleep quality) than the others. The young adults' group showed a significant negative correlation between the stress from social distancing and QOL (r=-0.27, p<0.05) and between PSQI and QOL (r=-0.48, p<0.05). For the middle-aged adults' group, there was a significant negative correlation between PSQI and QOL (r=-0.53, p<0.05). The old adults' group showed a significant negative correlation between the stress from social distancing and physical activity (r=-0.35, p<0.05) and PSQI (r=-0.50, p<0.05), while there was a significant positive correlation between physical activity and PSQI (r=0.30, p<0.05) and QOL (r=0.30, p<0.05). Conclusion: The results of this study could be used as basic data for the promotion of physical and mental health in the post-COVID-19 era.

The purpose of this study was to investigate whether differentiation of self mediates the relationship between parenting styles (i.e., care and overprotection) and the level of career decision-making among young adults. We separately measured the mother's and the father's parenting styles and five dimensions of differentiation of self that S. Je (1989) suggested. The data came from 387 young adults who were juniors and seniors at universities in Seoul and its surrounding cities. Using Baron and Kenny's (1986) steps based on regression, we found that the relationships between both caring and overprotective parenting styles and young adults' level of career decision-making were mediated by four dimensions of differentiation of self (i.e., intellectual functioning vs. emotional functioning, family projection process, emotional cutoff, and family regression) except for integration of self. The results were consistent for both the mother and the father. Bootstrapping tests showed that all of the mediation effects were statistically significant. This study contributes to the literature by showing that young adults' level of career decision-making is not simply determined by inputs such as parenting styles but is also mediated by differentiation of self. The results of this study are meaningful in that both the mother's and the father's parenting styles could make a difference in young adults' level of career decision-making through differentiation of self.

This study analyses young adults'perceptions of the meanings and motivations of parenthood. It also verifies the relationship between the meanings and motivations of parenthood by young adults. The sample population included 311 university students. Our findings show that young adults perceived parenthood variously as a personal lifestyle, and as an statement of social maturation and sound mind and of marital satisfaction. There were no differences by gender in their perceptions on the meaning of parenthood. As for the motivation to become parents, strengthening biological family ties, traditional norms, emotional and altruistic reasons, deepening marital bonds, and perpetuating one's self through the passing on of genes. Among these, altruistic-emotional motivation and marital cohesion were stronger than other motivations. Finally, we provide recommendations for future research.
