Purpose: The purpose of this study is to examine the cognitive function in the elderly and to identify the influencing factors. Methods: The design of this study was descriptive research design. A total of 139 elderly people (aged 65 years and over) visiting the electroencephalogram (EEG) center in Seoul, Korea were evaluated. Data were assessed by self-administered questionnaires and CNS Vital Signs (CNSVS). Data were analyzed using SPSS Statistics 23.0 for Windows. Results: There were significant differences in the Korean Mini-Mental State Examination (K-MMSE), executive functions and reasoning according to education level. K-MMSE, visual memory and executive functions were different depending on the jobs. Age was highly correlated with cognitive function. In addition, stepwise multiple regression analyses showed that the factor significantly associated with reaction time and visual memory was depression. Depression and Trait-Anxiety had significant impacts on executive functions and K-MMSE. Conclusion: CNSVS enabled the accurate and objective measurement of cognitive function. Therefore, this study provides useful data to improve cognitive function of the community-dwelling elderly. The results suggested that there is need for comprehensive interventional programs that manage cognitive impairment.

Indoor air quality tends to be the dominant contributor to personal exposure, because most people spend over 80% of their time indoors. In this study, indoor and outdoor NO$_2$ concentrations were measured and compared with simultaneously personal exposures of 21 university students in weekday and weekend. House characteristics and activity pattern were used to determine the impacts of these factors on personal exposure. Since university students spent most of their times in indoor, their NO$_2$ exposure was associated with indoor NO$_2$ level rather than outdoor NO$_2$ level both weekday and weekend in spite of different time activity. Using time-weighted average model, NO$_2$ exposures of university students were estimated by NO$_2$ measurements in indoor home, indoor school, and outdoor home levels. Estimated NO$_2$ personal exposures were significantly correlated with measured NO$_2$ personal exposures($r^2$=0.87). However, estimated personal NO$_2$ exposures by time-weighted average model were underestimated, comparing with the measured personal NO$_2$ exposure. Using multiple regression analysis, effect of personal NO$_2$ exposure for transportation was confirmed.

Purpose: The purpose of this study was to determine the impacts of vocational calling, emotional intelligence, and major commitment on nursing college students' happiness. This study also was conducted to explore major commitment's mediating effect on the relationship between vocational calling, emotional intelligence, and major commitment among nursing college students. Methods: Participants were 346 nursing college students. Data were collected in November, 2017 with self-report questionnaires and were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficients, and regression analysis with IBM SPSS 19.0. Results: The regression model explained 33.0% of variance in nursing college students' happiness (F=41.44, p<.001). Significant factors were emotional intelligence (${\beta}=.30$, p<.001), grade (${\beta}=.20$, p<.001), major commitment (${\beta}=.18$, p=.002), and vocational calling (${\beta}=.11$, p=.035). Moreover, major commitment showed partial mediating effects on vocational calling and happiness. Major commitment also showed partial mediating effects on emotional intelligence and happiness. Conclusion: The results suggest that nursing college students' happiness can be increased through strategies aimed at increasing vocational calling, emotional intelligence, and major commitment.

Purpose: Covid-19 has caused an unprecedented situation for the tourism industry with slumping demand during the outbreak and many uncertainties about tourist behavior in the post-pandemic. This study is aimed to discover the distribution in the behavior of tourists in Vietnam, whose government has taken serious and early actions towards the health crisis and among the earliest to reopen the economy. Research design, data, and methodology: We adopted a mixed-method approach - combining qualitative interviews with quantitative research using a questionnaire survey. Through the form of the online survey through social networking channels: Facebook, Gmail. The study received 261 valid responses for analysis. Multivariate analysis techniques were used: descriptive statistics, exploratory factor analysis (EFA). Results: From the data and result of EFA, the result showed that the distribution of tourist behavior could be grouped into four main factors, including (1) the general impacts, (2) travel-related behaviors; (3) attitudes and preferences regarding modes of tours and destinations; (4) awareness of safety and hygiene. Conclusions: These results highlighted the importance of the theory of perceived risks in explaining the travelers' prudent decisions. In addition, this study provides practical implications for policymakers and various stakeholders of Vietnam's tourism industry in formulating the recovery strategy.

Over the last few decades, the rates of pediatric obesity have more than doubled regardless of sociodemographic categorization, and despite these rates plateauing in recent years there continues to be an increase in the severity of obesity in children and adolescents. This review will discuss the pediatric obesity mediated cardiovascular disease (CVD) risk factors such as attenuated levels of satiety and energy metabolism hormones, insulin resistance, vascular endothelial dysfunction, and arterial stiffness. Additionally, early intervention to combat pediatric obesity is critical as obesity has been suggested to track into adulthood, and these obese children and adolescents are at an increased risk of early mortality. Current suggested strategies to combat pediatric obesity are modifying diet, limiting sedentary behavior, and increasing physical activity. The effects of exercise intervention on metabolic hormones such as leptin and adiponectin, insulin sensitivity/resistance, and body fat in obese children and adolescents will be discussed along with the exercise modality, intensity, and duration. Specifically, this review will focus on the differential effects of aerobic exercise, resistance training, and combined exercise on the cardiovascular risks in pediatric obesity. This review outlines the evidence that exercise intervention is a beneficial therapeutic strategy to reduce the risk factors for CVD and the ideal exercise prescription to combat pediatric obesity should contain both muscle strengthening and aerobic components with an emphasis on fat mass reduction and long-term adherence.

Purpose: This study was a descriptive research to identify the relationships among burden from behavioral psychological symptoms of dementia, dementia attitude, emotional labor and nurse's caring behavior as well as to clarify factors that affect caring behavior of nurses in long-term care hospital. Methods: For the research, this study collected data from July 8 to July 20, in 2019 with 214 nurses who worked at 10 long-term care hospitals in Chungbuk. The data were analyzed using descriptive statistics, t-tests, Mann-Whitney U test, ANOVA, Pearson's correlation coefficient, stepwise multiple regression with the SPSS 23.0 program. Results: Factors influencing caring behavior of nurses in long-term care hospital were dementia attitudes (β=.549, p<.001), burden from behavioral psychological symptoms of dementia (β=.242, p<.001) and marital status (β=.134, p=.017). These factors explained 33.9% of caring behavior (F=37.35, p<.001). Conclusion: Dementia attitudes were confirmed to be the main variable influencing nurse's caring behavior. Therefore, to improve the caring behavior of dementia patient, it is considered that the development of programs to improve dementia attitudes and in-depth understanding regarding the behavioral and psychological symptoms of dementia is necessary.

Traditional approaches for structural health monitoring (SHM) seldom take ambient uncertainty (temperature, humidity, ambient vibration) into consideration, while their impacts on structural responses are substantial, leading to a possibility of raising false alarms. A few predictors model-based approaches deal with these uncertainties through complex numerical models running online, rendering the SHM approach to be compute-intensive, slow, and sometimes not practical. Also, with model-based approaches, the imperative need for a precise understanding of the structure often poses a problem for not so well understood complex systems. The present study employs a data-based approach coupled with Empirical mode decomposition (EMD) to correlate recorded response time histories under varying temperature conditions to corresponding damage scenarios. EMD decomposes the response signal into a finite set of intrinsic mode functions (IMFs). A two-dimensional Convolutional Neural Network (2DCNN) is further trained to associate these IMFs to the respective damage cases. The use of IMFs in place of raw signals helps to reduce the impact of sensor noise while preserving the essential spatio-temporal information less-sensitive to thermal effects and thereby stands as a better damage-sensitive feature than the raw signal itself. The proposed algorithm is numerically tested on a single span bridge under varying temperature conditions for different damage severities. The dynamic strain is recorded as the response since they are frame-invariant and cheaper to install. The proposed algorithm has been observed to be damage sensitive as well as sufficiently robust against measurement noise.

Competition assures improved products and services to meet customers' needs. The soundness of a firm's financial health is crucial for the country's economic well-being. Distressed companies cause investor panic, which has a knock-on effect on the economy and leads to a deterioration in the image and value of the companies. This paper aims to empirically investigate the influence of competition on financial distress (FD) in the healthcare industry using the Altman Zscore values as the proxy for FD. This study uses secondary data from ten healthcare companies operating in India between 2016 and 2020. The study's findings indicate a significant negative relation with the exogenous variables of the study, implying that a higher level of competition enhances a firm's FD or adversely affects financial health. The main implication of the study is two-pronged. Firstly, the firms' managers and decision-makers need not worry about competition as a deterrent to stability. Secondly, the policymakers need not be concerned that high competition may lead to financial stress for the firms. Therefore, this paper concludes that competition is good for firms operating in India.

The bakery cafe and dessert industry in Korea is expanding, but it requires continuous innovation to remain competitive and adaptable. Therefore, this study aims to examine the effect of five sense factors on customer satisfaction and relationship continuance intention in Korean dessert cafes. A survey was conducted among 200 consumers who had visited a Korean dessert cafe in Seoul and Gyeonggi Province. Regression analysis was conducted for hypothesis testing, and the research results are as follows. First, among the five sensory factors in Korean dessert cafes, gustatory, visual, and olfactory factors positively impacted customer satisfaction and relationship continuance intention. These results suggest that the taste and presentation of Korean desserts in cafes and the aroma of both the desserts and the café are essential. However, auditory and tactile factors did not impact customer satisfaction and intention to continue the relationship. Second, customer satisfaction improved the intention to continue the relationship. This finding suggests that improving customer satisfaction in Korean dessert cafes positively impacts maintaining customer loyalty. Therefore, operators of Korean dessert cafes should consider gustatory, visual, and olfactory aspects when developing dessert menus and planning the physical environment of their restaurants.
