Purpose: This study was designed to find differences between physical activity and health-related factors of Korean male adults. Methods: Using the 2010 Korean National Health and Nutrition Examination Survey (NHANES V-1), the data of 1,876 Korean males over 30 years old who completed the Health Interview, Health Behavior Surveys and International Physical Activity Questionnaire (IPAQ) were analyzed. Analysis of differences in physical activity according to socio-demographic factors, physical health-related factors and psychological health-related factors was tested using the F-test and chi-square test with SPSS 12.0. Results: The high physical activity group was merely 2.5% and the moderate group was 51.4%. In each group, the study showed significant differences in age (p=.017), education status (p=.019), and economic status (p=.032) of socio-demographic factors, in body mass index (p=.003), vitamin D (p=.020) and hypertension status (p=.007) of physical health-related factors, and in recognition of stress (p=.027) of psychological health-related factors. Conclusion: These results revealed that physical activity can play an important role in nursing intervention of physical and psychological health-related factors in male adults.

Novel groups of uncultivable anaerobic thermophiles were isolated from compost by enrichment cultivation in medium with a cell-free extract of Geobacillus toebii. The cell-free extract of G. toebii provided the medium with growth-supporting factors (GSF) needed to cultivate the previously uncultured microorganisms. Twenty-nine GSF-requiring candidates were successfully cultivated, and 16 isolated novel bacterial strains were classified into three different groups of uncultivable bacteria. The similarity among these 16 isolates and a phylogenetic analysis using 16S rRNA gene sequences revealed that these GSF-requiring strains represented novel groups within the family Clostridiaceae.

The inositol polyphosphates are a group of multifunctional signaling metabolites whose synthesis is catalyzed by a family of inositol kinases that are evolutionarily conserved from yeast to humans. Inositol polyphosphate multikinase (IPMK) was first identified as a subunit of the arginine-responsive transcription complex in budding yeast. In addition to its role in the production of inositol tetrakis- and pentakisphosphates ($IP_4$ and $IP_5$), IPMK also exhibits phosphatidylinositol 3-kinase (PI3-kinase) activity. Through its PI3-kinase activity, IPMK activates Akt/PKB and its downstream signaling pathways. IPMK also regulates several protein targets non-catalytically via protein-protein interactions. These non-catalytic targets include cytosolic signaling factors and transcription factors in the nucleus. In this review, we highlight the many known functions of mammalian IPMK in controlling cellular signaling networks and discuss future challenges related to clarifying the unknown roles IPMK plays in physiology and disease.

Purpose: The purpose of this study was to investigate the recovery time and its related factors after sedative gastroscopy. Method: The subjects of this study consisted of 103 clients. The data were collected from clients who visited a health care system at S national university hospital in Seoul. The sedative gastroscopy was performed by gastrointestinal endoscopists. Patients' demographics and medical characteristics were assessed by reviewing the patients' charts. Degree of sedation and recovery were assessed by the Ramsay's sedation scale and the Aldrete score, respectively. Result: The mean recovery time was $37.8{\pm}16.9$ minutes(range, 5 to 90 minutes). Hypoxia was resent in four clients during recovery. Alcohol intake(p=0.02) and pulmonary function(p=0.003) were significant factors affecting recovery time, whereas midazolam dose and sedation level were not. Conclusion: Current alcohol intake, pulmonary function were predicting factors on recovery time.

Objective Personality traits can be the basis for individual differences in the biological response of stress. To date, many psychobiological studies have been conducted to clarify the relationship between personality and biological reactivity to stress. This review summarizes the most important findings in this area of research. Results Key findings related to the relationship between personality factors and stress-sensitive biological systems in four research models have been summarized; model of psychosocial characteristics, model based on Rumination and Emotional Inhibition, Eysenck's biopsychological model, and Five-Factor Approach of Personality. Conclusion According to the results of this review, it can be concluded that personality typology of individuals influenced their biological reactivity to stressful events. Understanding the biological basis of personality can help to better understand vulnerability to stress. Future research can be continuing based on framework of the four models.

Integrated stream naturalness based on abiotic and biotic factors were developed. Abiotic factors considered in this study were types of land use in the riparian area, river bank and high water bed streamside, revetment, bed substrate and artificial construction of streamside. Biotic factors included types of vegetation, assemblages of fish, macroinvertebrate, bird and mammal(Otter) in streams. The presence/absence of legal species and biological assessment index were also weighted as important parameters in this study. Scoring criteria selected for each matrix was five rating system; 1=poor, 2=moderate, 3=fair, 4=good, 5=excellent. Numerical ratings for the matrix were then summed. This resulted in a minimum score of 13 if all matrix at a site were poor, and a maximum score of 65 if all matrix were excellent. Five grade system from poor(I) to excellent condition(V) was employed. To verify its validity in natural environment, the evaluation system was applied to the Gapchun stream which is a test bed selected. Our result showed that stream naturalness of each reach was clearly distinguished by biotic and abiotic characteristics. Determination of correlation coefficient between abiotic and biotic factors was also high ($R^2=0.96$, p<0.05). In conclusion, assessment for stream naturalness reflecting abiotic and biotic factors was useful method representing stream integrated.

Purpose: This descriptive study was to explore the factors relating to Social Physique Anxiety(SPA) in the adolescent girls(N=700). These factors included the biological(level of school[age], period of menstruation, and BMI), the sociocultural(Influence of Mass Media, [IMM], Stereotype of Ideal Female Body[SIFB], type of school, perceived figure, and ideal figure) and the BW control-related factors(experience of bodyweight [BW] control, satisfaction at the result of BW control, and motive of BW control). Method: The sample was 700 girls of the middle and high schools in Jeju-do. The data was collected by the self-reported questionnaire and processed with the SPSS Win 12.0 program. Result: 26% of the variance in SPA was explained by the biological factors(level of school) and the sociocultural factors (perceived figure, ideal figure, type of school, and IMM). SPA, IMM, and SIFB were significantly correlated with each others(r=1,65-2.92, p<.05). The mean SPA scores according to BW control-related factors were significantly different. Conclusion: This results suggest that media education is necessary to reduce or eliminate the adolescent girl's SPA. In addition, SPA needs to be considered as the important concept for the future nursing researches and interventions related to BW control.

Major depression is a devastating disorder of which lifetime prevalence rate is as high as up to 25% in general population. Although the etiology of the disorder is still poorly understood, it is generally accepted that both genetic and environmental factors are involved in the precipitation of depression. Stressful lifetime events are potent precipitating environmental factors for major depression and early-life stress is in particular an important element that predisposes individuals to major depression later in life. How environmental factors such as stress can make our neural networks susceptible to depression and how those factors leave long-lasting influences have been among the major questions in the field of depression research. Epigenetic regulations can provide a bridging mechanism between environmental factors and genetic factors so that these two factors can additively determine individual predispositions to major depression. Here we introduce epigenetic regulations as candidate mechanisms that mediate the integration of environmental adversaries with genetic predispositions, which may lead to the development of major depression, and summarize basic molecular events that underlie epigenetic regulations as well as experimental evidences that support the active role of epigenetic regulation in major depression.

Purpose: Although long-term viral suppression and antiretroviral therapy (ART) success depend on sustained adherence, adolescents' adherence rates are suboptimal. Optimal adherence is influenced by various factors. Since Sub-Saharan Africa is home to over 80% of adolescents living with human immunodeficiency virus (HIV) and considering their unique characteristics and susceptibility to poor adherence, it is crucial to provide updated knowledge on adherence rates and their determinants among this population. This review aims to present up-to-date data on adherence rates and associated factors among HIV-positive adolescents in Sub-Saharan Africa. Methods: A systematic review was conducted following the PRISMA guidelines. The PubMed and Scopus databases were used to identify documents corresponding to the study's objectives. Eleven studies were included in this review after being selected from among all studies that were found online from 2017 to 2023. Results: The reported adherence rates ranged from 55% to 86%. In total, 32 factors were found to be related to adherence among HIV-positive adolescents in Sub-Saharan Africa. These included 12 adherence-facilitating factors and 20 adherence-inhibiting factors. The most often mentioned factors affecting adherence were advanced World Health Organization clinical stage (i.e., stage IV), ART dose and regimens, a lack of support, and violence victimization. Conclusion: Our findings can help healthcare providers collaborate with HIV-positive adolescents to improve ART adherence and ensure the best possible health outcomes.
