This study examined differences in the preference of the fest therapy program regarding stress level. Using convenience sampling method, the surveys on the preferred type of forest healing program and social and psychological stress scales was carried out for adult male and female. As a basis of Psycho social Stress Scale (PWI-SF: Psychosocial Well-being Index Short Form), the adult 620 people were classified such as healthy group, potential stress group, high-risk stress group. The data were analyzed by use of SPSS 21.0 program. To see the difference in preferences for forest therapy program between the three groups according to stress levels, it was analyzed using one-way ANOVA. Depending on the stress levels, there were differences in the preferences of forest healing program such as breathing, breathing exercises, walking in the forest, listening to the sound of water flowing, viewing the forest, counseling, consultation and expert coaching, stress-related lectures, communication-related lectures, forest bathing wind bathing sun bathing. High-risk stress group preferred cognitive based program such as counseling, consultation and expert coaching, stress-related lectures, communication-related lectures. Healthy group appeared to prefer highly emotional approach of the program to take advantage of the five senses such as breathing, breathing exercises, walking in the forest, listening to the sound of water flowing, viewing the forest, forest bathing, wind bathing, sun bathing. Noticeable preference difference was not observed in the potential stress group. It is hoped this study will serve as a basis for the development of forest healing program regarding stress level.

Kimchi is a Korean traditional fermented food with various health functionalities. However, the protective effects of kimchi against Alzheimer's disease (AD) have not been studied yet. In this study, the protective activities of kimchi extract against oxidative stress and AD were investigated in an amyloid beta ($A{\beta}$)-induced AD model using ICR mice. Kimchi extract exerted strong scavenging activities against 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radical. In addition, T-maze, object cognition, and water maze tests were carried out using the AD model. The $A{\beta}_{25-35}$-injected groups showed impairment of cognition and memory. However, the abilities of novel object recognition and new route awareness were improved by administration of kimchi extract (100 and 200 mg/kg/day) for 2 weeks. Furthermore, the results on water maze test indicated that kimchi extract exerted protective activity against cognitive impairment induced by $A{\beta}_{25-35}$. The present study suggested that kimchi protected against $A{\beta}$-induced impairment of memory and cognition as well as attenuated oxidative stress.

The main objective of this research was to grasp using a structure equation analysis if an auxiliary police officer unit's measure of getting rid of assault gets to their adaptation to the unit through stress factor to reveal the cause of an auxiliary police officer unit's adaptation to unit. The data used for the research is survey data of all auxiliary police officer belonging to Ulsan Metropolitan Police Agency in 2011. The result of structure equation analysis showed that the mediated effect through stress was statistically meaningful in the level of p<.001. Also, the result of confirming the size of effect through standardized regression coefficients was that the effect of stress upon the adjustment to units was higher than the effect of unit's measure of getting rid of assault. Namely, unit's measure of getting rid of assault has a positive effect upon a conscripted policemen unit's adaptation to unit, but it showed that an auxiliary police officer unit's adaptation to unit had the bigger individual stress factor than that of unit's measure of getting rid of assault. From this, authorities should recognize that an auxiliary police officer's stress is a cause to determine their adaptation to units, and prepare its alternative.

Recently, identification of the extremely stressed condition of children is an essential skill for real-time recognition of a dangerous situation because incidents of children have been dramatically increased. In this paper, therefore, we present a model based on machine learning techniques for stress status identification of a child by using bio-signals such as voice and heart rate that are major factors for presenting a child's emotion. In addition, a smart band for collecting such bio-signals and a mobile application for monitoring child's stress status are also suggested. Specifically, the proposed method utilizes stress patterns of children that are obtained in advance for the purpose of training stress status identification model. Then, the model is used to predict the current stress status for a child and is designed based on conventional machine learning algorithms. The experiment results conducted by using a real-world dataset showed that the possibility of automated detection of a child's stress status with a satisfactory level of accuracy. Furthermore, the research results are expected to be used for preventing child's dangerous situations.

Objectives : This study was intended to compare coping style, family support, and parenting behavior between adolescent groups with different levels of perceived stress. Methods : A total of 795 high school students participated in this study. First, they were tested on the Perceived Stress Scale and then were separated into two groups depending on the level of perceived stress. Both groups completed the Scale for the Coping Style, the Family Environment Scale (relationship subscale) and Parenting Behavior Inventory. Results : The high stress group had significantly higher scores on all their coping scores than the low stress group. Also, the high stress group had significantly higher family conflict scores, lower family cohesiveness scores and lower expression scores than the low stress group. The high stress group experienced negative parenting behavior from both parents more often than the low stress group. In the adolescents with low family cohesiveness and expression, the use of active behavioral coping was decreased, if the higher stressful events occurred. The use of avoidant coping by these adolescents increased when there were higher levels of stress in their environment. Conclusion : Low family support directly reduced the usage of active behavioral coping and increased the use of avoidant coping strategy through the mediation of high stress condition.

The purpose of this study was to identify the factors related to allergic diseases based on the health behavior of the youth in multicultural families according to the data from Tenth Korea Youth Risk Behavior Web-Based Survey 2014 (Centers for Disease Control & Prevention). The subjects from 712 multicultural adolescents were analyzed by the SPSS program. For the characteristics of health behavior of the multicultural youth, 267 students (37.5%) have experienced drinking alcohol, 164 students (23.0%) have experienced smoking, and 35 students (4.9%) have experienced taking drugs. Also, 198 students (27.8%) were depressed, 259 students (36.3%) are suffering from stress, and 286 students (40.2%) failed to fully relieve fatigue. In addition, 497 students (69.8%) consider themselves as healthy, 449 students (63.1%) consider themselves as happy, and 251 students (35.3%) consider themselves as overweight. Among the allergic disease of the multicultural youth, 46 middle school students (6.5%) and 35 high school students (4.9%) have asthma, 95 middle school students (13.3%) and 87 high school students (12.2%) have allergic rhinitis, and 67 middle school students (9.4%) and 53 high school students (7.4%) have atopic dermatitis. 47 male students (6.6%) and 34 female students (4.8%) have asthma, 81 male students (11.4%) and 101 female students (14.1%) have allergic rhinitis, and 53 male students (7.4%) and 67 female students (9.4%) have atopic dermatitis. Among the multicultural youth, 81 students (11.4%) have asthma, 182 students (25.5%) have allergic rhinitis, and 120 students (16.8%) have atopic dermatitis. For the allergic diseases from the health behavior of the multicultural youth, depression (p<0.001), alcohol experience (p<0.05), drug experience (p<0.05), health recognition (p<0.05), happiness recognition (p<0.05), and body type recognition (p<0.05) had a statistically significant relationship with asthma. Fatigue recovery recognition (p<0.001), health recognition (p<0.001) and stress recognition (p<0.05) had a statistically significant relationship with allergic rhinitis. Body type recognition (p<0.01), depression (p<0.05), fatigue recovery recognition (p<0.05), health recognition (p<0.05), and happiness recognition (p<0.05) had a statistically significant relationship with atopic dermatitis. Such results show that schools and society need to educate the multicultural youth about health, happiness, and body type recognition which are big factors of allergic diseases. Schools and society also need to be more systematic and continuous in order to help multicultural youth to be have correct recognition of depression, stress and fatigue recovery.

This study was conducted to determine the impacts of perceived stress and empathy ability on altruistic behavior of freshman nursing students. Data were collected from 160 freshman nursing students between 24 November and 9 December 2016. A total of 154 questionnaires were analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation coefficient, and Stepwise multiple regression. The results showed that perceived stress had significant negative correlations with altruistic behavior (r=-0.178, p=0.028) as did positive perception, a subfactor of perceived stress (r=-0.347, p<0.001). However, empathy ability was significantly positively correlated with altruistic behavior (r=0.607, p<0.001). The factors influencing altruistic behavior included emotional empathy, cognitive empathy and positive perception, with emotional empathy being the most influential factor (${\beta}=0.320$), followed by cognitive empathy (${\beta}=0.312$), which together had an explanatory power of 41.6%. Moreover, there was a mediating effect of empathy ability in the relationship between positive perception and altruistic behavior. Overall, the results of this study indicate that the management of curricula for nursing college students should search for ways to reduce their perceived stress as well as increase their empathy ability in order to improve their altruistic behavior.
