The purpose of this study is to examine the effect of care workers' assistance services on behavioral changes of the elderly. To achieve this, a survey was carried out on 100 elderly people, who receive the services from care workers in J area-based elderly care facilities, and elderly patient families. The results of this study are as follows. First, the effect of care workers' assistance services on the elderly's satisfaction of physical activities showed that the nursing and caregiving services have a significant positive effect on their satisfaction of physical activities(p<.05). Second, the effect of care workers' assistance services on the elderly's satisfaction of psycho-emotional activities showed that the caregiving services have a significant positive effect on their satisfaction of psycho-emotional activities(p<.01). Third, the effect of care workers' assistance services on the elderly's satisfaction of social cognition activities showed that the caregiving services have a significant positive effect on their satisfaction of social cognition activities(p<.01). Consequently, if the elderly receive the repetitive and continuous nursing and caregiving service in the limit that is forced to deteriorate the elderly's physical, psychological and cognitive development, and slow down their activities, there will be changes and promotion in their physical, psychological and cognitive behaviors. In other words, it is of use in that care workers' continuous assistance services can improve the elderly's life, driven by the changes of their physical, psychological and cognitive behaviors.

Prior studies have shown positive effects of outdoor activities on the elderly's physical, mental and social health. 'Active aging' and 'age-friendly' neighborhood can be created by modifying the experiences and perceptions of the outdoor environment. This study aims to investigate the outdoor activities of the elderly living in a low-income elderly concentrated area and their perception of the neighborhood environment. We also explored the context of interactions between the facilitators and inhibitors of outdoor activities on the basis of temporal, spatial, and social conditions. We used a mixed method approach by collecting two different types of qualitative GIS data : observation maps of the main places and individual cognitive maps with in-depth interviews. The observational map analysis indicated that the preferred places and activity patterns differ by age, gender, and size of the group. The cognitive map and interviews demonstrated that the elderly's activity goals and perception of the landscape differ by places such as forests, parks, streams, open-spaces, vegetable gardens, and alleys. The elderly's desire for outdoor activities can be better fulfilled when their front doors and alleys are well-connected to an open-sight pleasant space. Familiarity is an important factor for the elderly, therefore it is important to remove the psychological and physical barriers by increasing the legibility and accessibility of places. In addition, social interactions and conflicts can have a significant influence on the elderly's occupation of space in the neighborhood environment.

Background: The purpose of this study was to identify the risk factors influencing cognitive function and life satisfaction in elderly living alone. Methods: It was cross-sectional descriptive study by using secondary data from the 2014 national survey of Korean elderly. The study sample consisted of 2,249 subjects who live alone, aged 65 years old and over. Data were analyzed frequency analysis, ${\chi}^2$-test, t-test, ANOVA and Logistic regression analysis. Results: The risk factors that significantly influenced cognitive function were old age, bereavement, lack of education, no regular exercise and low socio-cultural activity satisfaction. The risk factors that significantly influenced life satisfaction were no bereavement, lack of education, no work, negative evaluation of health status, diagnosis of depression and no regular exercise. Also experience of emotional and economical abuse, neglect of financial support and low cognitive function were identified risk factors of life satisfaction. Conclusions: The elderly living alone with risk factors of cognitive decline should be interested. To prevent or delay cognitive impairment, regular exercise and socio-cultural activities were recommended. It was suggested that the promotion of cognitive function, appropriate work and exercise, and social efforts to prevent abuse and neglect can contribute to improving life satisfaction of elderly living alone.

This study was designed to examine the relationships among the levels of perceived stress, dietary behaviors, physical exercise, drinking, smoking, and relief from fatigue through sleep which affect the subjective happiness in adolescents. Based on the study findings, this paper proposes the basic data required for offering practical solutions to improve the subjective happiness of adolescents. IBM SPSS 20 and AMOS 23 were used to conduct frequency and descriptive analyses, in conjunction with Pearson's correlation coefficients, the AMOS bootstrapping method and phantom variables, for the raw data obtained from the 9,599 participants included in the 11th Korea Youth Risk Behavior Web-based Survey. Those factors having a direct effect on the subjective happiness of the adolescents were the level of perceived stress, relief from fatigue through sleep, physical exercise, dietary behavior and smoking. Perceived stress had an indirect effect on subjective happiness, and the analysis of the indirect effect and significance level of multiple mediators by means of phantom variables showed that, as well as perceived stress, relief from fatigue through sleep, physical exercise, dietary behaviors, and smoking also had indirect effects on subjective happiness. Consequently, a multidisciplinary approach is needed to optimize the subjective happiness in adolescents and financial support for environmental improvements is particularly necessary.

The purpose of this study was to research the effects of socio-demographic factors and values in each group on satisfaction with life by categorizing the activity types of the elderly into volunteer work and economic activities. The subjects of this study were 60 years an old higher. The questionnaires were categorized depending on activity types and collected. The voluntary work group consisted of 201 people (76 males, 36.8% and 125 females, 62.2%), The economic activity group consisted of 219 people (127 males, 58.0% and 92 females, 42.0%). The SPSS 14.0 Windows program was used to analyze data. Frequency, average, standard deviation, factor analysis, Pearson correlation coefficient, t-test, One-Way ANOVA analysis, and hierarchical multiple linear regression were analyzed. The major findings of this study indicate that the elderly in the voluntary work group have a high collectivism value, higher income earned by performing economic activities, and good cognitive health affected by a high satisfaction with life. From these research results, it was proved that a collectivism value is a common factor that affects satisfaction with life in both of the economic activity group. Those who were older had a traditional collectivism value. The voluntary work group showed a stronger collectivism value and higher satisfaction with life than the economic activity group. Thus, the diverse types of voluntary work should be developed and a systematic system should be established as methods for improving quality of life and satisfaction.

Problem posing in school mathematics is generally regarded to make a new problem from contexts, information, and experiences relevant to realistic or mathematical situations. Also, it is to reconstruct a similar or more complicated new problem based on an original problem. The former is called as problem generation and the latter is as problem reformulation. The purpose of this study was to explore the co-relation between problem generation and problem reformulation, and the educational effectiveness of each problem posing. For this purpose, on the subject of 33 pre-service secondary school teachers, this study developed two types of problem posing activities. The one was executed as the procedures of [problem generation${\rightarrow}$solving a self-generated problem${\rightarrow}$reformulation of the problem], and the other was done as the procedures of [problem generation${\rightarrow}$solving the most often generated problem${\rightarrow}$reformulation of the problem]. The intent of the former activity was to lead students' maintaining the ability to deal with the problem generation and reformulation for themselves. Furthermore, through the latter one, they were led to have peers' thinking patterns and typical tendency on problem generation and reformulation according to the instructor(the researcher)'s guidance. After these activities, the subject(33 pre-service teachers) was responded in the survey. The information on the survey is consisted of mathematical difficulties and interests, cognitive and affective domains, merits and demerits, and application to the instruction and assessment situations in math class. According to the results of this study, problem generation would be geared to understand mathematical concepts and also problem reformulation would enhance problem solving ability. And it is shown that accomplishing the second activity of problem posing be more efficient than doing the first activity in math class.

Group play for sociality is a therapeutic method involving a mixture of various factors, such as targeted activities, perceptions, and physical mobility required in daily life, through group activities to encourage self-expression for the purpose of facilitating sociality. This study was conducted in order to verify its effects by applying it to autistic adolescents who lack communicative ability with others and ultimately to improve their interpersonal relationships and sociality. This study applied a single pre- and post-test experiment design to 8 autistic adolescents with lack of sociality who use a daycare center in Daejeon. The group play for sociality program consisted of two sessions a week for 7 weeks from October to December 2013 for a total of 14 sessions. The sociality of the adolescents before and after the intervention was analyzed by the Wilcoxon signed-rank test. As a result of the study, the total grades of the E-CLAC and social maturity test showed significant changes from $39.88{\pm}6.78$ to $47.00{\pm}4.28$ and $49.96{\pm}28.00$ to $61.36{\pm}21.75$, respectively. In detail, there were significant changes in the sub-items, such as adjustment in group, following guidance, and increasing behavioral frequency. In conclusion, it was shown that the combined effect of the group activities, including group play for sociality and play activities taking into consideration the developmental stage of the participants, led to a significant improvement in the sociality of the autistic adolescents.
