This study investigated associations between healthy dietary practices and the odds of prediabetes among Korean adolescents. The data of 1,624 adolescents aged 12 to 18 who participated in the 2017-2021 Korea National Health and Nutrition Examination Survey were analyzed. Healthy dietary practices were defined according to Health Plan 2030 criteria, and prediabetes was defined as a fasting blood glucose level of 100-125 mg/dL. After controlling for confounders, adjusting odds ratios and 95% confidence intervals (CIs) for prediabetes were determined for different healthy dietary practices using multivariable logistic regression analysis. Compared with adolescents who engaged in healthy dietary practices, those who did not had a 1.63-fold (95% CI: 1.12-2.37) higher odds of prediabetes. In addition, adolescents who did not consume ≥500 g of fruit and vegetables daily and those who refrained from reading nutritional fact labels, which are both subindicators of healthy dietary practices, had a 1.66 (95% CI: 1.05-2.62) and 1.58-fold (95% CI: 1.06-2.37) higher odds of prediabetes, respectively, than those who did. Increasing the proportion of adolescents engaging in healthy dietary practices, such as consuming ≥500 g of fruit and vegetables daily and reading nutritional fact labels when selecting food, is imperative.

Background: Hemiparesis not only affects the affected side but also exerts an impact on the unaffected side. Stroke patients endure muscular weakness attributable to hemiparesis, resulting in asymmetry of muscular strength between the paralyzed and non-paralyzed sides. Objectives: To investigate the correlation between lower limb muscle strength asymmetry and functional factors in patients with stroke. Design: A cross-sectional study. Methods: A total of 58 stroke patients participated in this study. After measuring the muscle strength of both lower limbs using manual muscle testing, the asymmetry was calculated. Functional factors such as berg balance scale (BBS), timed up and go (TUG), 10-metre walk (10MW), and modified barthel index (MBI) were measured. Results: The BBS showed positive correlations with hip, knee, and ankle strength asymmetry (P<.05). The TUG showed negative correlations with hip, knee, and ankle strength asymmetry (P<.05). The 10MW showed negative correlations with hip, knee, and ankle strength asymmetry (P<.05). The MBI showed positive correlations only with hip strength asymmetry (P<.05). Conclusion: We were found that there is a more pronounced lower limb muscle strength asymmetry in the lower extremity of stroke patients, which is associated with BBS, TUG, and 10MW.

This study aimed to determine the association between household types and healthy dietary practices among Korean adults. A cross-sectional analysis was performed using nationwide data on 23,488 participants from the 2017-2021 Korea National Health and Nutrition Examination Survey (KNHANES). Based on self-reported data, the participant household types were classified into single- and multi-person households. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for healthy dietary practices according to household types were calculated by applying multivariable logistic regression analysis after adjusting for confounders. Of total, 11.21% and 88.79% were single- and multi-person households, respectively. Compared with individuals living in multi-person households, those in single-person households had lower odds of adhering to healthy dietary practices (AOR: 0.88, 95% CI: 0.79-0.98) and consuming adequate saturated fatty acids (<7% of energy) (AOR: 0.78, 95% CI: 0.69-0.88). In addition, men and individuals aged 65 years living in single-person households exhibited lower odds of consuming adequate saturated fatty acids and 500 g of fruit and vegetables per day than those in multi-person households. Single-person households often find it a challenge to practice a healthy diet. Hence, nutritional policies and educational support that help individuals living alone consume healthier diets are warranted.

Background: Copy number variation (CNV) can be identified using next-generation sequencing and microarray technologies, the research on the analysis of its association with meat traits in livestock breeding has significantly increased in recent years. Hanwoo is an inherent species raised in the Republic of Korea. It is now considered one of the most economically important species and a major food source mainly used for meat (Hanwoo beef). Methods: In this study, CNVs and the relationship between the obtained CNV regions (CNVRs) can be identified in the Hanwoo steer samples (n = 473) using Illumina Hanwoo SNP 50K bead chip and bioinformatic tools, which were used to locate the required data and meat traits were investigated. The PennCNV software was used for the identification of CNVs, followed by the use of the CNV Ruler software for locating the different CNVRs. Furthermore, bioinformatics analysis was performed. Results: We found a total of 2,575 autosomal CNVs (933 losses, 1,642 gains) and 416 CNVRs (289 gains, 111 losses, and 16 mixed), which were established with ranged in size from 2,183 bp to 983,333 bp and 10,004 bp to 381,836 bp, respectively. Upon analyzing the restriction of minor alleles frequency > 0.05 for meat traits association, 6 CNVRs in the carcass weight, 2 CNVRs in the marbling score, 3 CNVRs in the backfat thickness, and 2 CNVRs in the longissimus muscle area were related to the meat traits. In addition, we identified an overlap of 347 CNVRs. Moreover, 3 CNVRs were determined to have a gene that affects meat quality. Conclusions: Our results confirmed the relationship between Hanwoo CNVR and meat traits, and the possibility of overlapping candidate genes, annotations, and quantitative trait loci that results depended on to contribute to the greater understanding of CNVs in Hanwoo and its role in genetic variation among cattle livestock.

The purpose of this study was to investigate the association between household economic changes by COVID-19 and dietary habits in Korean adolescents. The study analyzed data from the 17th Korea Youth Risk Behavior Survey in 2021. A total of 54,848 middle and high school students, 28,401 males and 26,447 females, participated in this study. COVID-19 lead to deterioration of household economy in the lower level of household economic status (p<0.001). The deterioration of household economic status by COVID-19 was associated with dietary habits such as lower breakfast intake, and higher fast food, soda drinks, and sweet drinks consumption (p<0.001). Logistic regression analysis showed that deterioration of household economic status was significantly decreased in frequency of breakfast intake (OR: 0.73, 95% CI: 0.67~0.80). The deterioration of household economic status by COVID-19 was also significantly associated with increased frequency of fast food (OR: 1.28, 95% CI: 1.16~1.41), soda drinks (OR: 1.42, 95% CI: 1.30~1.56) and sweet drinks (OR: 1.35, 95% CI: 1.24~1.46) consumption (p<0.001). In conclusion, it was confirmed that the change in household economy caused by COVID-19 was associated with dietary habits in adolescents. As the household economy deteriorated, there was an increase in undesirable dietary habits including skipping breakfast and fast food consumption.

We performed a study to examine the association between diet quality and nonalcoholic fatty liver disease (NAFLD). Our study included 3,586 women aged 40-64 years who participated in the sixth Korea National Health and Nutrition Examination Survey. The study subjects were classified into the NAFLD group (n=816) and the normal group (n=2,770) using the hepatic steatosis index. The anthropometric indices, blood profiles, and dietary intake data of the subjects were obtained. The waist circumference, body mass index, and the serum levels of triglycerides, fasting blood sugar, HbA1c, and systolic and diastolic blood pressures were higher in the NAFLD compared to the normal groups (p<0.001, respectively). The intakes of protein (g/kg body weight, p<0.001), potassium (p<0.001), and vitamin A (p=0.006) were significantly lower in the NAFLD group. It was observed that the higher the total Korean Healthy Eating Index score, the lower the risk of NAFLD. A reverse relationship was shown between the NAFLD risk and the intakes of total fruits, total vegetables, vegetables excluding Kimchi and pickled vegetables, meat, fish, eggs and beans. Therefore, it is recommended that middleaged women in Korea increase their intakes of fruits, vegetables, and foods high in protein for the proper management of NAFLD.

Previous works on safety behavior have paid less attention to the influence of several leadership styles on safety behavior. Among the various leadership styles, I focus on the effect of coaching leadership on safety behavior. To be specific, this paper investigates the impact of coaching leadership on safety behavior and its underlying mechanisms (mediator) as well as contextual factor (moderator). This research examines the sequential mediating effect of perceived organizational support and organizational identification in the association between coaching leadership and safety behavior. Also, work overload will negatively moderate the coaching leadership-perceived organizational support link. My results showed coaching leadership increases employee safety behavior through the sequential mediation of perceived organizational support and organizational identification. In addition, work overload functions as a negative moderator which diminishes the positive effect of coaching leadership on perceived organizational support.

이 연구는 ‘임을 위한 행진곡’의 제창･합창을 둘러싼 5･18 광주민주화 운동의 위기 속에서 세계호남인들이 결속하게 된 경위를 살펴보는 데 있 다. 연구 결과는 다음과 같다. 첫째, 한국의 산업화 시기에 호남인들은 생활환경이 열악한 고향을 떠나 타지로 향했다. 서울 경기 등 수도권지 역으로의 이동이 압도적으로 많았지만, 부산･경남･경북지역 등 국내에서 거듭 이동하게 되었다. 둘째, 세계호남인의 결속은 집단 내부에 공유하고 있는 ‘거시기’로서 통하는 사회적 인지와 암묵적 인지로써 호남인의 정서 와 호남인의 정신이 깔려 있기 때문으로 생각된다. 셋째, 세계호남향우회 는 동일한 역사적 경험과 문화를 공유한 호남인의 역사적 산물이자 5･18 광주민주화운동이 탄생시킨 지역공동체 운동이라 할 수 있다. 넷째, ‘임 을 위한 행진곡’은 5･18 광주민주화운동의 상징적인 노래로 정권 교체기 에 갈등이 표출되는 양상을 보여왔는데 이러한 위기의식은 세계호남인을 결속시키는 역할을 해왔다. 다섯째, 세계호남인향우회의 ‘3무 정책’은 ‘약 한 연대(Weak Ties)’의 효과를 최대화하여 호남인들이 글로벌 연대를 조 직하여 협력할 수 있는 원동력이 되었다. 결론적으로 세계호남향우회는 지방자치단체의 지원과 회원의 자발적 장학금 모금을 통한 차세대 지역 인재 양성으로 지속이 가능한 모국방문 프로그램의 가능성을 보여준 것 으로 생각된다.

In this study, we identified the differences in food content watching habits and nutrition quotient in adolescent (NQ-A). A total number of 811 subjects were surveyed to establish their general characteristics, food content watching habits, and NQ-A using a self-administered questionnaire. In addition, the mediating effect of watching motivation between the type of food content watched and the NQ-A score was determined. The classification by the type of the food content mainly watched showed that 405 participants (49.9%) watched the Mukbang content, 244 (30.1%) the Cookbang content, and 162 (20.0%) another contents. Among the content watching motives in the Cookbang content group, information acquisition and enjoyment were predominant, whereas emotional satisfaction had the lowest frequency. Compared to the Mukbang content group, when the Cookbang content group mediated information acquisition motivation, the scores of the total, diversity, balance, and practice of NQ-A score areas increased. Compared to the Mukbang content group, the score in the moderation area decreased when the Cookbang content group mediated enjoyment motivation. If food content with accurate information and interesting content are produced and used for adolescent nutrition education, the education will be highly effective.

In this study, we aimed to explore whether eating alone is associated with mental health conditions in Korean adolescents. The data of 2,012 Korean adolescents aged 12-18 years were obtained from the Korea National Health and Nutrition Examination Survey 2015–2019. Participants were classified into three groups based on the frequency of eating alone: none (all meals with others); 1 meal/day alone; and 2 meals/day alone. Mental health conditions were assessed based on stress recognition, depressive symptoms, and suicidal ideation. Multivariable logistic regressions were employed to calculate the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) of poor mental health conditions according to the frequency of eating alone. Adolescents who ate 2 meals/day alone had higher odds of stress recognition (AOR: 2.65, 95% CI: 1.94- 3.63), depressive symptoms (AOR: 2.55, 95% CI: 1.47-4.42), and suicidal ideation (AOR: 2.53, 95% CI: 1.05-6.08) than those who ate all their meals with others. In addition, having breakfast or dinner alone increased the odds of stress recognition. Considering the continuous increase in the social phenomenon of eating alone, nutritional educations are needed to develop adolescents' ability to choose more nutritionally balanced and healthy meals when eating alone.

There has been growing attention on the well-being of people with disabilities. The purpose of this study was twofold: (1) to investigate the associations between individuals’ socio-demographic and psychological characteristics and clothing expenditure, and (2) to examine the moderated mediation effect of self-efficacy and acceptance of disability on the association between dependency on others and happiness among people with visual impairment. This study was based on secondary analysis of data from the second wave of the 6th Panel Survey of Employment for the Disabled collected by the Employment Development Institute. The results of this study showed that average monthly expenditure on clothing was positively associated with self-efficacy, happiness, and acceptance of disability, while being negatively associated with dependency on others. The results also confirmed that self-efficacy mediated the association between dependency on others and happiness. A conditional direct effect of dependency on others on happiness was found, in which negative associations were significant among people with visual impairment who had low and mean levels of acceptance of disability (but not high levels). In addition, there was a significant conditional indirect effect, in which the indirect and negative effect of dependency on others on happiness via self-efficacy was significant for those with low and average levels of acceptance of disability. These findings support the importance of enhancing the independence and acceptance of disability among people with visual impairment, which ultimately contributes to their happiness.

The endothelium, a continuous monolayer of cells that surrounds blood vessels, has a variety of physiological roles. Chronic exposure to psychological and physical stress, oxidative stress, and inflammation activates the endothelial signaling cascade, resulting in vascular dysfunction such as vasospasm, thrombosis, and abnormal vascular proliferation. Aging is also a significant factor in vascular dysfunction, mainly developing structural and functional changes in the endothelium. The molecules involved in endothelial dysfunction are typically angiopoietin-1 (Ang-1), Tie2, and tight junction proteins. Ang-1, an oligomeric-secreted glycoprotein, is required for the correct organization and maturation of newly-formed vessels. Ang-1 binding to tyrosine kinase receptors Tie-2 leads to the phosphorylation and activation of multiple signaling pathways related to vascular permeability. Endothelial junctions are another vital target of Tie-2 activation. Nutrition and food are closely connected with vascular dysfunction and permeability. The caloric restriction prevents age-related declines in endothelial function. Dietary patterns that prioritize moderate intake of fruits and vegetables, whole grains, low-fat dairy products, and lean meats improve endothelial function in the elderly. Natural products such as Centella asiatica, Pueraria montana, and Piper retrofractum have also been shown to help inhibit endothelial dysfunction. This review provides an update on aging-related vascular dysfunction and the role of food and nutrition.
