Objectives : Anemia is a common problem in the management of elderly patients. Recent studies reported that anemia was associated with cognitive impairment and Alzheimer's disease. This study was aimed to analyze the differences of hemoglobin levels in Korean patients with Alzheimer's disease(AD) dementia, mild cognitive impairment(MCI), and healthy controls. Furthermore, the study also examined if any association between hemoglobin levels and cognitive functions existed. Methods : A total of 116 Korean elderly adults were participated in this study(mean age 74.67 years ; 60.3% female). The Korean version of the Mini-Mental State Examination(MMSE-K), Clinical Dementia Rating(CDR) and Global Deterioration Scale(GDS) were applied to all subjects. Hematological and related blood chemistry values were investigated. Results : We found that patients with AD dementia had significantly lower hemoglobin and hematocrit levels than MCI subjects and healthy control group. The hemoglobin levels showed a positive correlation with MMSE-K and negative correlation with CDR, GDS. Conclusions : Among Korean elderly, low hemoglobin level is associated with a cognitive impairment. This study indicates that AD is associated with anemia, and low hemoglobin levels may contribute to potentially useful clinical markers of AD. The risk factor for dementia needs to be confirmed by prospective longitudinal studies in a larger group of patients.
The purpose of this study was to examine how the level of self-compassion of correctional workers influenced depression and the simple and double mediating effects of job stress and job autonomy. Although correctional officers experience high levels of stress and depression, there are limited strategies to protect their job performance. The total of 210 correctional workers in S. Korea were included in the final analysis using SPSS PROCESS Macro model 6. For the analysis, Korean Self-Compassion Scale (K-SCS), Korean occupational stress scale (KOSS), and Center for Epidemiological Studies Depression Scale (CESDS) were used. The results of the study were as follows. First, the correlation analysis showed statistically significant relationships between the variables(p<.01). Second, the simple mediating effect of job autonomy was found in the relationship between the self-compassion and depression as well as the double mediating effect of job stress and job autonomy. The influences of low level of self-compassion on mental health (depression) could be modified by improving the level of work related empowerment (job autonomy) as a protective factor. Based on the results of the study, the further study suggestions and limitations were discussed.

This study was conducted to investigate the effects of adolescent health behavior on obesity using an online health behavior survey. The subjects of this study were 12,090 middle school students and 14,248 high school students among 26,338 Korean youths that responded to an online survey of youth health behaviors in 2018 (14th). There were significant differences in lifestyle, mental factors, exercise habits, and sitting habits as health behavior factors. The risk of obesity was higher in smokers (p<0.001), drinkers (p<0.001), those who ate breakfast less than four times a week (p<0.001), those who consumed fruit less than four times a week (p<0.001) and those who ate fast food less than two times a week (p<0.001). The obesity rate was higher in people with high-stress (p<0.05). Exercise habit as a factor was higher in the obesity rate than in physical activity by three times as much (p<0.001), whereas students categorized as muscular (p<0.01) had one to two times more physical activity (p<0.001). Students who had less than six hours of learning purpose were found to have higher obesity rates than those with more than six hours of learning purpose (p<0.001). In conclusion, the obesity rate did not increase with prolonged sitting habits, but did increase with longer sitting time except for those who studied purpose folly. Therefore, it is necessary to have a set time for internet use, as well as to educate schools about proper lifestyle, and to promote healthy exercise habits.
The mitochondria is the major cellular organelle of energy metabolism for the supply of cellular energy; it also plays an important role in controlling calcium regulation, reactive oxygen species (ROS) production, and apoptosis. Mitochondrial dysfunction causes various diseases, such as neurodegenerative diseases, Lou Gehrig's disease, cardiovascular disease, mental disorders, diabetes, and cancer. Most of the diseases are age-related diseases. In this review, we focus on the roles of mitochondrial dysfunction in cancer. Mitochondrial dysfunction induces carcinogenesis and is found in many cancers. The factors that cause mitochondrial dysfunction differ depending on the types of carcinoma, and those factors could cause cancer malignancy, such as resistance to therapy and metastasis. Mitochondrial dysfunction is caused by a lack of mitochondria, an inability to provide key substances, or a dysfunction in the ATP synthesis machinery. The main factor associated with cancer malignancy is mtDNA depletion. Mitochondrial dysfunction would leads to malignancy through changes in molecular activity or expression, but it is not known in detail which changes lead to cancer malignancy. In order to explore the relationship between mitochondrial dysfunction and cancer malignancy in detail, mitochondria dysfunctional cell lines are constructed using chemical methods such as EtBr treatment or gene editing methods, including shRNA and CRISPR/Cas9. Those mitochondria dysfunctional cell lines are used in the study of various diseases caused by mitochondrial dysfunction, including cancer.
The purpose of this study is to determine the inhibiting factors of dying well for people who want to have a good death. The final respondents in this study were sampled using stratified proportional allocation using a stratified random sampling method, and 1,000 adults aged between 19 and 75 years were selected. The questionnaire used consisted of four items on general characteristics and 20 items related to the inhibiting factors of dying well scored on a 7-point Likert scale. Analysis was conducted using descriptive statistics, correlation analysis, and decision tree analysis. Results showed that, among the inhibiting factors of dying well, "degenerative diseases (such as dementia)" and "loss of control (mental / physical)" scored 5.502 and 5.268 points, respectively; the highest significant positive correlation was found between "bad marital relationship" and "bad relationship with children," followed by "did not receive death education" and "lack of medical policy promotion (dying well)" and "bad relationship with children" and "indifference of others." Considering these findings, it appears that the whole society will make efforts to improve the perception and practice of good death, and life and death education will be expanded if death education for dying well is organized and implemented.

Objective : The purpose of this study was to investigate prevalence of psychiatric symptoms and determine predictors of emotional distress of military hospital surgical patients. Methods : This study examined 104 orthopedic patients admitted to the Armed Forces Military Hospital September-November 2018. For the study, every subject completed self-assessment inventories regarding depressive and anxiety symptoms (Hospital Anxiety and Depression Scale), sleep problems (Pittsburgh Sleep Quality Index), problematic alcohol and tobacco use (Cut off, Annoyed, Guilty, Eye-opener screening), and psychiatric history. We performed the Student's t-test and the chi-square test for the collected data to investigate the prevalence of psychiatric symptoms, including emotional distress. Logistic regression analysis was used to examine the risk factors related to emotional distress of hospitalized military personnel. Results : There were no significant differences in socio-demographic and psychiatric symptoms between soldiers and officers. The prevalence of depressive and/or anxiety symptoms (emotional distress) was 21.2% (n=21). In the logistic regression analysis, psychiatric history [Adjusted Odds Ratio (AOR)=18.99 ; 95% Confidence Interval (CI)=1.42-253.57 ; p=0.026] and low military life satisfaction (AOR=15.67; 95% CI=1.46-168.11 ; p=0.023) correlated with emotional distress. Conclusion : Soldiers admitted to the military hospital showed similar prevalence of emotional distress as those at general hospitals. Considering military circumstances, it is necessary to detect and intervene regarding soldiers with a psychiatric history and low military life satisfaction to promote mental health at military hospitals.
The purpose of this study is to examine the effect of forest healing programs with walking, sightseeing, and forest scent among six healing forest treatments using forest environment on the cognitive function, depression, and quality of life of elderly living alone. The subjects of the study were 17 senior citizens living in Samcheok and complaining of severe depression and forgetfulness. They were divided into two groups, and each group participated in the six sessions of the weekly forest healing program. All of them were surveyed of a Korean version of the MMSE-K, BDI (Beck Depression Inventory Korean Version), and SF-36 (Short Form 36 health survey questionnaire) with the questionnaire designed for the one-group pre-post test to examine changes in cognitive function, depression, and quality of life. The results showed that the mental status, depression level, and quality of life of respondents were significantly higher after healing programs. These results suggest that participation in healing program activities using forest environment can improve cognitive function, relieve depression and improve quality of life for senior citizens living alone. Therefore, inducing older adults who live alone and avoid outside activities to participate in the regular forest healing program will contribute to the prevention of dementia due to age and environment.

The purpose of this study was to investigate the prevalence of social anxiety among late School-aged Children and identify factors influencing the tendency to social anxiety. A self-report survey was conducted with primary school children who were in the 6th grades. Two hundred and seventy eight children were included in the study. The instruments utilized in this study were SASCA-K (Korean Social Anxiety Scale for children and adolescents), SES(Self-esteem Scale), CAPS(Child and Adolescent Perfectionism Scale), DSRS-C(Depression Self-Rating Scale for Children), and IPPA-R(Inventory of Parent and Peer Attachment-Revised version). Data were analyzed using descriptive statistics, t-test, One-way ANOVA, Pearson correlation and multiple regression with SPSS WIN 23.0 program. Social anxiety for the schoolchildren was positively correlated with perfectionism and depression, whereas self-esteem and attachment security was negatively correlated with social anxiety. Stepwise multiple regression analysis showed that 38.0% of the variance for social anxiety was significantly accounted for by self-esteem, self-oriented perfectionism, depression, attachment security (Father-communication). The most significant factor influencing social anxiety was self-esteem. Findings suggest that expanding health education, counseling and school-based health education programs is necessary to prevent and intervention mental problems of late School-aged Children through integrated intervention by schools, families and communities.

This study examined the effect of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet of the Korean multi-domain dementia prevention program on the cognitive functions of the elderly with dementia risk factors. We developed the program including nutrition, exercise, cognitive training, vascular disease prevention, and motivation. One- hundred and fifty-three participants aged 60~79 years with at least 1 dementia risk factor were randomly assigned in a 1:1:1 ratio to the facility-based intervention (FMI), home-based intervention (HMI), and the control group. The nutrition education program consisted of 10 classes over 24 weeks: the FMI received 7 group sessions and three 1:1 sessions, the HMI received 4 group sessions and three 1:1 sessions with 3 homework sessions. The Nutrition Quotient for Elderly (NQ-E) and the Mini Nutritional Assessment (MNA) were used to evaluate nutritional status. The Repeatable Battery for the Assessment Neuropsychological Status (RBANS), Korean Mini-Mental State Examination (K-MMSE), and the Cognitive Complaint Interview (CCI) were used to evaluate cognitive functions. A total of 136 people completed the program with an 11.1% dropout rate. The NQ-E (P=0.009) and RBANS (P=0.001) scores significantly increased in the FMI (N=45) and HMI (N=49) groups compared to the control group (N=42) after the study. The changes in the score of MNA and CCI did not differ significantly between groups. In conclusion, the nutritional intervention which focused on the MIND diet as a part of a multi-domain intervention program had a positive effect on the improvement of healthy eating habits and cognitive function scores in the high-risk dementia group.
Fibromyalgia is a disorder characterized by the core symptom of chronic widespread pain, along with fatigue, sleep disturbances, mood changes, and cognitive difficulties. The etiology of fibromyalgia involves a combination of biological factors, such as genetic vulnerability, alterations in pain processing and stress response system ; psychological factors, such as anxiety, depression, anger, and perceived stress ; environmental factors, such as infections, febrile diseases, and trauma. Central sensitization, which is amplified in the process of sensory stimulation, has been emphasized as a key etiological factor, as supported by enhanced wind-up, delayed aftersensation, decreased nociceptive flexion reflex threshold and functional imaging studies. Several guidelines recommend that a multimodal approach be used to treat fibromyalgia, including both pharmacological and non-pharmacological treatments, tailored to each individual, and that clinicians should provide an intellectual framework through sufficient education and emphasis on the importance of self-management. The prevalence of mood disorders, anxiety disorders, and other psychiatric problems is 7-9 times higher in patients with fibromyalgia than in the general population ; moreover, the association between fibromyalgia and certain psychopathologies or sleep problems has also been suggested. Since psychiatric problems, with shared vulnerabilities and risk factors, interact with fibromyalgia bidirectionally and also affect the disease course, an integrated management approach is needed to determine the risk of comorbidities.
