Purpose: This study was conducted to obtain data for the development of an effective fall risk assessment tool for pediatric inpatients through a systematic review and meta-analysis of the diagnostic test accuracy of existing scales. Methods: A literature search using Medline, Science Direct, CINAHL, EMBASE, and the Cochrane Library was performed between March 1 and 31, 2018. Of 890 identified papers, 10 were selected for review. Nine were used in the meta-analysis. Stata version 14.0 was used to create forest plots of sensitivity and specificity. A summary receiver operating characteristic curve was used to compare all diagnostic test accuracies. Results: Four studies used the Humpty Dumpty Falls Scale. The most common items included the patient's diagnoses, use of sedative medications, and mobility. The pooled sensitivity and specificity of the nine studies were .79 and .36, respectively. Conclusion: Considering the low specificity of the pediatric fall risk assessment scales currently available, there is a need to subdivide scoring categories and to minimize items that are evaluated using nurses' subjective judgment alone. Fall risk assessment scales should be incorporated into the electronic medical record system and an automated scoring system should be developed.

Purpose: The study aims to identify factors that influence university students' compliance with infection prevention behaviors in the early stage of COVID-19. Methods: A survey was conducted online from July 29 to August 2, 2020, involving 261 students enrolled in general universities. Frequency analysis, descriptive statistics, t-test, ANOVA, correlation, and multiple regression analysis were carried out on the collected data using SPSS 24.0. Results: The average score of university students' risk perception of COVID-19 was 3.80, while the average score of health risk communication was 3.92. The average score of efficacy beliefs was 4.42 and the average score of practicing infection prevention behaviors was 4.54. Factors influencing the level of infection prevention behaviors were efficacy of preventive behaviors (β=.48 p<.001), health risk communication (β=.16, p=.003), subjective health status (β=.12, p=.015), and the type of college (β=.11, p=.041). Conclusion: In order to improve college students' infection prevention behaviors related to COVID-19, consideration should be given to providing interventions that focus on accurate knowledge and dissemination of accurate information about new infectious diseases and effectiveness of infection preventive behaviors.

The purposes of this study were to investigate the effects of farming in greenhouses with respect to subjective fatigue symptoms among farmers and the degree of symptoms. The study compared 176 green-house farmers with 216 open field farmers using a subjective fatigue symptoms rating scale developed by the Industrial Research Institute of Fatigue, Japanese Association for industrial Hygiene. 1. With respect to complaint rates of the subjective fatigue symptoms, the results indicated that greenhouse farmers have, in order of severity, high degrees of low back pain, difficulty in collecting thoughts, and apt to forget. 2. With respect to cumulative scores of fatigue symptoms, the results indicated that both groups of farmers exhibited a lack of attentiveness and a high degree of dullness and sleepiness(category I), body projection of fatigue(category II), and difficulty in concentration(category III). 3. With respect to general characteristics, it was found that the degrees of subjective fatigue symptoms were found to be higher among females, people with lower educational levels, and the elderly, regardless of the group. 4. With respect to work related factors, farmers with more years of experiences were found to have higher degrees of subjective fatigue symptoms, except for open field farmers with less than nine years experience. Both groups of farmers were found to have high degrees of subjective fatigue symptoms when working less than eight hours a day and less than six months a year. 5. With respect to health habits, for people who get less than eight hours of sleep per day exhibited higher fatigue scores than people who get more than eight hours. People who do not smoke and drink also exhibited higher fatigue scores than people who smoke and drink. 6. The results of multiple regression showed that the risk factors related to the subjective fatigue symptoms of farmers in the greenhouse group were ages, levels of education, sex and for the comparison group, were sex. years of farming, and hours of sleep. The R-square were 12.5% in the greenhouse group and 12.1% in the comparison son group. The differences between the greenhouse and open field farmers in the degrees of fatigue symptoms were found not to be statistically significant even if the working conditions of the greenhouse farmers were poor. This may be attributed to non-work related factors, i.e., social, economical, and psychological factors among greenhouse farmers.

Objectives: The purpose of this study was to investigate the relationship between the level of subjective stress recognition and oral symptom experiences including toothache, gum diseases, and oral soft tissue diseases in the Korean adolescents. Methods: The subjects were 68,043 adolescents recruited using a web-based survey, National Korean Youth Risk Behavior in 2015 by the Korean Center for Disease Control. For statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to determine the factors associated with general characteristics, health behaviors, oral health behaviors, and level of subjective stress recognition. Finally, to investigate the relationship between the level of subjective stress recognition and oral symptom experiences, logistic regression analysis was performed. Results: Toothache related subjective stress recognition level was significantly higher in the moderate group with the score of 1.59 (95% CI; 1.49-1.68), and was greater in the high group with 2.38 (95% CI; 2.24-2.53) compared to the low group. Gum disease related subjective stress recognition level was significantly higher in the moderate group with 1.41 (95% CI; 1.32-1.51), and was greater in the high group with 1.99 (95% CI; 1.86-2.13). Oral soft tissue disease related subjective stress recognition level was significantly higher in the moderate group with 1.59 (95% CI; 1.45-1.74), and was greater in the high group with 2.55 (95% CI; 2.33-2.79). Bad breath related subjective stress recognition level was significantly higher in the moderate group with 1.48 (95% CI; 1.39-1.57), and was greater in the high group with 2.10 (95% CI; 1.97-2.25). Conclusions: Higher subjective stress recognition level was found to affect the oral symptoms experienced. Therefore, the stress management plan should be prepared through the cause identification of the main stress in the adolescents. Practical and systematic education is needed for oral health management in the schools.

Objective: This study was to investigate the effects of coordinated upper-limb body postures on the subjective discomfort rating, heart rate, and muscle activities. Background: Although generally many checklists such as OWAS, RULA, and REBA were applied to evaluate various body postures, the body postures were might be overestimated or underestimated because each body part(i.e., back, shoulder, and elbow etc.) was evaluated separately, and then added all rates of individual body parts to assess an overall risk level for the body posture in these methodologies. Methods: A total of 20 participants maintained 14 postures which were combinations of back, shoulder, and elbow flexion angles and then muscle activities, subjective discomfort, and heart rates were collected every three minute during a sustained 15 minute and 0.5kg weight holding task. Four muscle groups were investigated: erector spine, anterior deltoid, upper trapezius, triceps brachii. Results: Results showed that subjective discomfort was the lowest when the angle of back and shoulder were both $0^{\circ}s$, while the body posture with $45^{\circ}$ of back angle and $45^{\circ}$ shoulder angle was rated as the most subjective discomfort posture. In general, the subjective discomfort ratings increased as back and shoulder flexion angles increased. It was noted that, however, the subjective discomfort of body posture with a $45^{\circ}$ back angle and $45^{\circ}$ shoulder flexion angle was lower than that of body posture with a $0^{\circ}$ back and $45^{\circ}$ shoulder flexion angle. The research findings of heart rates and muscle activities showed similar results for the analyses of subjective discomfort ratings. Conclusions: The possible limitations of the current ergonomics evaluation techniques which assessing a body posture with summing all body part score after individually analyzed in this study. Based on the analyses of subjective discomfort, heart rate, and muscle activities, it was recommended that a use of effects of coordinated upper-limb body postures would be considered when one evaluates work-load for various working postures. Application: These findings can be used for developing a more accurate assessment checklist for working posture as well as preventing musculoskeletal disorders of workers in workplaces.

This study examined the relationship between social support and the subjective well-being of the elderly living in urban areas. The study subjects were 382 elderly people aged 65 or older living in D metropolitan city. The survey was conducted through a personal interview by investigators who visited the study subjects using a structured questionnaire from May 1 to June 30, 2019. As a result, the subjective well-being of the study subjects differed significantly depending on various variables in the sociodemographic, health condition and, health-related behavior characteristics. The subjective well-being according to social support was significantly lower for the groups with lower social support. The correlation of subjective well-being and social support showed a significant positive correlation. Logistic regression showed that the risk of lower subjective well-being increased significantly in the group (Q1), where the total score of social support was very high (Q4). The above results suggest that the subjective well-being of the elderly living in urban areas was not only related to various variables in sociodemographic, health condition, and health-related behavior characteristics but also has significant relationships for social support. Therefore, it is necessary to develop detailed social support practices to improve the subjective well-being.

This study identifies the determinants that influence attitude toward and the intention to use mobile shopping services through fashion applications (apps) based on the technology acceptance model. In addition, gender and age group differences were examined. Data were collected from subjects who have used smartphone fashion related apps; subsequently, a total of 327 data were analyzed. About 46% of respondents were males, with a mean age of 34.4 years that ranged from 20 to 49 years old. Multiple regression models were developed based on the research model. Perceived usefulness, perceived ease of use, perceived enjoyment, perceived risks (security risk and quality risk), fashion involvement, and fashion app attributes (product attributes and service attributes) were employed as predictors of attitudes towards mobile shopping. Attitudes towards mobile shopping and subjective norms with the aforementioned variables measured the intention to use. Attitudes towards mobile shopping were predicted by perceived enjoyment, perceived usefulness, and service attributes. Attitudes toward mobile shopping and subjective norms were the most important predictors of the intention to use. Gender differences were found in that service attributes were significant for attitudes towards mobile shopping only in the male model. Age differences were also found and perceived usefulness was the most important predictor of attitudes toward mobile shopping among those in their 20's; however, perceived enjoyment was the most important among those in their 30's and 40's. Quality risk was only significant to explain intention to use among those in their 40's. The findings of this study are useful to understand the possibility of the adoption of mobile shopping though fashion apps and provide basic insight into market segmentation.

The purpose of this study was to assess the relationship between drinking patterns and depressive mood, and to understand the factors associated with depressive mood among problem drinkers. Data of 19,878 adults over 19 years of age and older from the third Korea National Health and Nutrition Examination Survey were evaluated by multivariate logistic regression analysis. The risk of depressive mood was greater with higher level of problem drinking in both genders. For male problem drinkers, the factors associated with depressive mood include older age, lower education level, unemployment, high perceived stress, bad subjective health status, and non-married status. For female, higher risk was found in groups with the age of 40-49, lower education level, unemployment, high perceived stress, and bad subjective health status. By early screening of the identified risk factors, progression to mental health problem can be avoided. For preventative measures, differential approach depending on gender is suggested.

Background: Despite social gradients in adult smoking, the effects of socioeconomic position (SEP) on adolescent smoking is not well understood. This study examined effects of subjective SEP as well as the objective SEP on smoking among Korean adolescents. Materials and Methods: Data were obtained from the 2012 Korea Youth Risk Behavior Web-based Survey, a nationally representative sample of middle and high school students (38,221 boys; 35,965 girls). SEP was assessed by the Family Affluence Scale (FAS) and the self-rated household economic status. Relationships between SEP and smoking were analyzed by multivariate logistic regression. Results: The low perceived SEP for either the high or low FAS grade was related to an elevated likelihood of smoking in both genders. A significantly higher risk of smoking was found in boys of low perceived SEP in middle school (odds ratio [OR] 1.50; 95% confidence interval [CI] 1.28-1.77 for high FAS, OR 1.55; 95% CI 1.21-1.98 for low FAS), and of low perceived SEP and high FAS in high school (OR 1.13; 95% CI 1.02-1.26). Among girls, an elevated risk of smoking was observed in middle school group with low perceived SEP and low FAS (OR 2.01; 95% CI 1.44-2.79) and in the high school group of low perceived SEP, regardless of FAS level (OR 1.34; 95% CI 1.14-1.57 for high FAS, OR 1.31; 95% CI 1.04-1.65 for low FAS). Conclusions: The relationship of subjectively perceived SEP with smoking is as important as objective SEP and more significant in Korean high school adolescents.

Several studies about hospital malnutrition have been reported that about more than 40% of hospitalized patients are having nutritional risk factors and hospital malnutrition presents a high prevalence. People in a more severe nutritional status ended up with a longer length of hospital stay and higher hospital cost. Nutrition screening tools identify individuals who are malnourished or at risk of becoming malnourished and who may benefit from nutritional support. For the early detection and treatment of malnourished hospital patients , few valid screening instruments fur Koreans exist. Therefore, the aim of this study was to develop a simple, reliable and valid malnutrition screening tool that could be used at hospital admission to identify adult patients at risk of malnutrition using medical electrical record data. Two hundred and one patients of the university affiliated medical center were assessed on nutritional status and classified as well nourished, moderately or severely malnourished by a Patient-Generated subjective global assessment (PG-SGA) being chosen as the 'gold standard' for defining malnutrition. The combination of nutrition screening questions with the highest sensitivity and specificity at prediction PG-SGA was termed the nutrition screening index (NSI). Odd ratio, and binary logistic regression were used to predict the best nutritional status predictors. Based on regression coefficient score, albumin less than 3.5 g/dl, body mass index (BMI) less than $18.5kg/m^2$, total lymphocyte count less than 900 and age over 65 were determined as the best set of NSI. By using best nutritional predictors receiver operating characteristic curve with the area under the curve, sensitivity and 1-specificity were analyzed to determine the best optimal cut-off point to decide normal or abnormal in nutritional status. Therefore simple and beneficial NSI was developed for identifying patients with severe malnutrition. Using NSI, nutritional information of the severe malnutrition patient should be shared with physicians and they should be cared for by clinical dietitians to improve their nutritional status.
