The purpose of this study was to understand the ability of the elderly to activity of daily living, assess their quality of sleep and level of depression at home and analyze how such relate health related quality of life. The subject was 223 senior over 65 years old who lived in B Metropolitan City. Descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation and stepwise multiple regression were performed using SPSS WIN 14.0. The major findings of this study are as follow: 1) 34.1% of the respondents experienced a degree of sleep disorder and 57.8% were vulnerable to depression. 2) Activity of daily living, quality of sleep and depression were related to health related quality of life to a statistically significant degree. quality of sleep, activity of daily living positively related to health related quality of life. level of depression related to health related quality of life. Stepwise multiple regression analysis revealed the most powerful predictor of health related quality of life was depression. While age, level of education and quality of sleep were also found as significant predictor variables. Based on these results, it is necessary to perform more studies on health related quality of life and related factors according to that in various settings. Especially, to develop a program intended to improve the health related quality of life of the elderly at home, we need to consider not only physical factors but also psychological factors.

Purpose: The purpose of this study was to investigate the effects of nutrient intake and dietary diversity score (DDS) on osteoporosis after controlling for sex, age, socioeconomic level, drinking, smoking, physical activity, and body mass index (BMI) as mediators using the 2015-2017 Korean National Health and Nutrition Examination Survey (KNHANES) data. Methods: This study was focused on the age group of 50s and older by using the 2015-2017 KNHANES data. Subjects diagnosed with osteoporosis were classified as the osteoporosis group, and the other subjects were classified as the normal group. Logistic regression was used to assess the association between nutrient intake and DDS after controlling for mediators. Results: The risk of osteoporosis was 2.38 times lower in the 50-65 age group than in the 75 years and older group. The mediators affecting the incidence of osteoporosis by age group were sex, age, household income level, and education level in the 50-64 age group; sex, education level, drinking, and BMI in the 65-74 age group; and sex, age, current smoking, drinking, BMI, and energy intake in the 75 years and older group. The effect of nutrient intake on osteoporosis, with the exception of vitamin B1, was fully mediated by these mediators. The effect of vitamin B1 was partially mediated by mediators in the age group of 65-74 years, and vitamin B1 was effective for preventing the risk of osteoporosis by 25% when consumed over EAR. The effect of DDS was partially mediated in the age group of 75 years and older, and DDS of 2 or less increased the risk of osteoporosis by 2.59 times. Conclusion: As a result of this study, it is necessary to recommend the balanced intake of various foods including grains, meat·fish·legumes, vegetables, fruits, and dairy products as dietary guidelines for the prevention of osteoporosis and promotion of bone health in the elderly.

This study conducted a systematic review of evidence-based interventions to confirm the importance of gait in dementia patients and to inform the necessity of various interventions necessary for gait. Based on PRISMA's guidelines and evidence-based intervention, a systematic review were conducted, and papers published in domestic journals for the past 10years were collected, and the dependent variables measured along with the intervention type and gait were analyzed. For data search, research papers from January 2011 to June 2020 were collected through RISS, KISS, the National Library of Korea, and the Library of Congress. The main search terms were 'dementia patient', 'walking', and 'walking ability'. Searched 57 papers on dementia patients and gait that meet the literature selection criteria. Among them, papers overlapping with papers before 2010, papers whose dependent variable is not related to gait ability were excluded, and finally, other than dementia diseases. As for the type of gait intervention, there were many programs related to exercise such as fall prevention and physical activity, and the dependent variables measured along with gait were physically and psychologically diverse. Although domestic studies for dementia patients are conducted in a variety of directions and methods, there are few studies on the improvement of function and gait of the lower extremity part of the body. Therefore, it is necessary to study the multifaceted and various intervention methods for walking in dementia patients.

The purpose of this study is to investigate the level of knowledge that mothers have on child development. To do so, a Knowledge of Child Development Inventory(KCDI) developed by Larsen &Juhasz(1986) was carried on to 156 mothers with an infant range from birth to age 24 months. The findings of the study were twofold: First, 70% of the questions on average were answered correctly by the participants. In other words, mothers generally demonstrated a high level of knowledge on child development. With regard to knowledge of child development, their knowledge on physical development of children was relatively low in comparison with that of cognitive and emotional development. In addition, mothers with a girl were more aware of child development especially in relation to child's emotional development. Also, mothers who delivered a heavier baby at birth possessed a higher level of knowledge concerning child's physical development. Second, other external factors, such as the level of family income and mother's education, played a significant role in affecting the level of knowledge on child development. Unsurprisingly, mothers with a higher income and education level demonstrated a higher level of knowledge on child's cognitive development. The findings of the study implicates that mothers seldom demonstrate a proper level of knowledge on child development. Hence, this study suggests that a practical, functional training services and resources for current and future mothers must be ensued.

Stress has been linked to the pathophysiology and pathogenesis of various psychiatric illnesses. Over the past few years, our understanding of the brain and neuroendocrine systems that are linked to stress responses has increased enormously. This article reviews a series of animal and human studies to understand what are the central pathways by which stress is perceived, processed, and transduced into a neuroendocrine response. We focus on the limbic-hypothalamic-pituitary-adrenal(LHPA) axis and several neurotransmitter systems such as norepinephrine, CRF, serotonin, acetylcholine, and dopamine. LHPA stress circuit is a complex system with multiple control mechanisms which are altered in pathological states. CRF and related peptides in the central nervous system appear to enhance behavioral responses to stressors. Norepinephrine systems are also activated by stressors and cause the release of catecholamines from the autonomic nervous system. CRF-norepinephrine interaction makes a feed-forward system which may be important for an organism to mobilize not only the pituitary system but also the central nervous system, in response to environmental challenges. The interactions among several neurotransmitters and endocrine systems appear to play key roles in mediating various behavioral and psychological stress responses involving abnormal responses to stressors such as anxiety and affective disorders.

Objectives : There have been several evidences that the central nervous system defect is one of the etiologic factors in schizophrenia and high nailfold plexus visibility can reflect these defects indirectly. These are particularly related to the negative symptoms of schizophrenia. In this study, we examined the relationship between nailfold plexus visibility and various clinical variables in schizophrenia. Methods : Forty patients(20 males, 20 females) satisfying the DSM-lV criteria for schizophrenia and forty normal controls(20 males, 20 females) were measured for Plexus Visualization Score (PVS) by using capillary microscopic examination. We used Positive and Negative Syndrome Scale(PANSS), Ulmann-Giovannoni Process-Reactive Questi-onnaire(PRQ), Phillips Premorbid Adjustment Scale(PAS), Continuous Performance Test, and Backward Masking for psychopathology and clinical variables. Results : There was no significant relationship between schizophrenic subjects and normal controls in PVS. PVS was correlated with PANSS positively except negative symptom subscore. PVS was correlated with PRQ score negatively, and with PAS score positively. Conclusions : This study shows high PVS are associated with more severe psychotic symptoms and with clinical variables, such as disease process and premorbid adjustment, in some schizophrenics.
