The purpose of this study is to investigate the relationships between the homemaker's stress and their home management behavioral patterns in Money and Time focusing on the Morphogenic & Morphostatic. This research aimed to ' 1) Identify the overall tendency of homemaker's stress & home management behavioral patterns 2) Find out if socio-demographic variables(ie. age of homemakers, level of education, duration of marriage, umber of children, homemaker's employment, socioeconomic status) have significant effects on homemaker's stress and their home management behavioral patterns, 3)Identify the correlation between homemakers' stress and home management behavioral patterns. 4) Find out variables which have independently significant effect on home management behavioral patterns. For these purpose, this research conducted a survey by using questionnaire developed by former researchers. The subjects of this study are 500 homemakers living in Kwangju who have at least one child. The data analyzed occording to frequency, percentage, mean , one-way ANOVA, Duncan's multiple range test. Pearson's correlation and multiple regression. The main findings are as follows; 1) General tendency of the stress level percepted by the homemakers is relatively low 2) socio-demographic variables have significant effects on the stress of homemakers. Among them only homemaker's age. the number of children and socio-economic status have influe d on the stress of urban homemakers. In each area, there are differences among groups; homemaker's age, durations of marriage, number of children in the area of family; age, number of children, socio-economic status in th area of health; age. durations of marriage. number of children, socio-economic status in the area of finance; socio-economic status in the area of household work. 3) General tendency of homemakers behavioral patterns is some what morphostatic. 4)socio-demographic variables have significant effects on the behavioral patterns of home management, a)Homemaker's age, the level of education, socio-economic status is a variable to have influences on home management behavioral patterns of the Money. b)The age homemakers is a variable to have influences on home management behavioral patterns of the time. c)The age of homemakers, duration of marriage is a variable to have influences on the home management behavioral patters of the resources. 5)There are positive relationship between homemaker's stress and home management behavioral patterns .

In early-age concrete, volumetric deformations due to thermal expansion and moisture transfer are restrained by various boundary conditions, and then restraint stresses occur in proportion to developed stiffness. With increase of the age, these stresses are gradually relieved by significant relaxation behavior of early-age concrete. Therefore, it is necessary to consider the stress relaxation in order to analyze the behavior of early-age concrete more accurately. In this paper, we propose a unified algorithm which combines a relaxation model with hydration model, heat conduction model, micropore structure formation model, moisture diffusion model and mechanical properties development model and develop a finite element program based on the algorithm. The program is applied to evaluate stress development if a temperature-stress test machine (TSTM) specimen and a massive concrete structure, and then validity of the program is discussed and evaluated.

The purpose of this research was to delineate the effect of parenting stress of the children's self-esteem. Such variables as the mother's age, her education level and maternal parenting stress were chosen for the analysis. The sample subjects were 659 pairs of fifth/sixth grade of elementary school and first/second grade of middle school and their mothers. The major findings of the research were as follows : First, the children's self-esteem was significantly different to mother's education level but the children's self-esteem not significantly different to mother's age. Second, parenting stress related to temperament, relationship and learning expectation was significantly different to children's self-esteem. Third, the result of stepwise multiple regression analysis on the effects of the maternal variables(mother's age, her education level, parenting stress) to the children's self-esteem indicated that maternal parenting stress related to temperament, relationship and mother education level were the significant contributing factors.

Job stress weakens physical ability causing the diseases related to working condition, decreases a production level, and increases mistakes and accidents. This study examined the relationship between job stress and human error, and focused on the moderating effect of age and maintenance type on the relationship between job stress and human error. The study used a quantitative design based on the 450 questionnaires of maintenance personnel in the Air force. The results of multiple regression analysis showed that physiological and psychological stress responses have positively related with human error. In moderating effect test, age appeared to impact on the relationship between physiological/behavioral stress and human error.

This study examined the influences on maternal acceptance-rejection and mediating effects of parenting stress. Participants were 150 mothers of children aged 3 to 6 in Seoul and Jeju. Research questions were analyzed by structural equation modeling. Results showed that children's age, congenital diseases or anomalies, planned pregnancy, and father's occupation influenced maternal acceptance-rejection directly. Mothers' perceived treatment in childhood and fathers' age influenced parenting stress; parenting stress, in turn, influenced maternal acceptance-rejection. Fathers' age influenced parenting stress negatively; parenting stress, in turn, influenced maternal acceptance-rejection positively.

This study examined the longitudinal effects of media usage by early school-age children and of maternal parenting stress on children's school adjustment. The study focused on the mediating effect of executive function difficulty. Longitudinal data to examine the hypothetical model were drawn from the eighth (2015) through tenth (2017) waves of the Panel Study of Korean Children (PSKC) collected by the Korea Institute of Child Care and Education (KICCE). A total of 581 children (293 boys and 288 girls) and their mothers were included. Confirmatory factor analysis, structural equation model, and bootstrapping analysis were applied using SPSS 25.0 and Amos 26.0. The results are as follows. First, no significant correlation was found between early school-age children's media usage and maternal parenting stress. Second, neither media usage by early school-age children nor maternal parenting stress were found to directly affect children's school adjustment. Third, media usage by early school-age children and maternal parenting stress were shown to indirectly affect children's school adjustment via executive function difficulties. In other words, higher levels of media usage by early school-age children and maternal parenting stress during the first grade lead to greater executive function difficulties after a year, which, in turn, lead to a lower level of school adjustment in the third grade. This study indicates the need to develop practical support for the psychological wellbeing of mothers while they are performing their role as a parent and for children in maintaining suitable levels of media usage during early childhood.

Tea polyphenols especially catechins have long been studied for their antioxidant and radical scavenging properties. Scientists throughout the world have investigated the usefulness of the regular green tea consumption in several disease conditions. In-vitro and in-vivo experiments on catechins especially epigallocatechingallate have revealed a significant role in many ways. Reactive oxygen species have been increasingly implicated in the pathogenesis of many diseases and important biological processes. Toxic effects of these oxidants, commonly referred to as oxidative stress, can cause cellular damage by oxidizing nucleic acids, proteins, and membrane lipids. Oxidative stress has been related to aging and age related disorders. It is found that in a wide variety of pathological processes, including cancer, atherosclerosis, neurological degeneration, Alzheimer's disease, ageing and autoimmune disorders, oxidative stress has its implications. Catechins have been reported to be useful in combating aging and age related disorders like cancer, cardiovascular disorders and neurodegenerative diseases. In this mini review we will discuss such studies done across the globe.

According to the Korea National Statistical Office data in 2010, the population over ages of 65 years would possess to 11.3% whole population of Korea in 2011 denoting Korea is already in the aging society. Old age is associated with inevitable time-dependent losses in physical capabilities. However the maintenance of physical capabilities is essential for continuing independence in old age. The work ability index(WAI) was constructed to reveal how well a worker is able to perform his work. This study focused on the discovery of an industrial and age-related influences on the work ability and job stress of workers in the shipbuilding, house managing, apartment construction industry. For this, the study conducted a job stress test using the Korean Occupational Stress Questionnaire Short Form, and employee performance evaluations using the Work Ability Index (WAI) of the Finnish Institute of Occupational Health (FIOH) on 3,228 workers in the shipbuilding, house managing and apartment construction industry. SPSS 12.0 K statistics program was used for statistics analysis and significance was verified with the Kruskal-Wallis test, a corporate body of nonparametric statistical analysis. As a result, employee performance had significant differences, depending on age, an industrial and years of service. The mean WAI score of the shipbuilding industry was lower than that of the other industry. Additionally, it was found that employee work ability decreased more as job stress increased.
