This study examined the mediating effect of internal locus of control in the relationship between family and friend support and acculturative stress of North Korean adolescent refugees. Participants consisted of 101 North Korean adolescent refugees (40 males and 61 females) aged 13 to 24, who live in Seoul, Gyeonggi Province, and Busan. SPSS 25.0 and Mplus 5.12 were used to analyze data. Descriptive statistics and Pearson's correlation coefficients were calculated and structural equation modeling (SEM) examined the mediating effect. The results of this study are as follows. First, a higher level of family support and friend support were associated with a higher level of internal locus of control. A higher level of internal locus of control was associated with a lower level of acculturative stress among North Korean adolescent refugees. Second, the level of internal locus of control mediated the relationship between friend support and acculturative stress. This study is meaningful in that it examines the specific paths affecting acculturative stress of North Korean adolescent by examining family and friend support, which are environmental factors, and internal locus of control, which is internal factor of individuals. The study results suggest that improving friend support as well as increasing the level of internal locus of control for North Korean adolescent refugees can be an effective way to prevent or intervene acculturative stress.

The purpose of this study is to find out influential variables related to Home Management Ability of urban home makers. This study focuses on the following aspects; 1) to find out which variables of sociodemographic variables (ie. home maker's age, level of education-husband, wife, job-husband, wife, income, duration of marriage), of psychological variables (ie. degree of resourcefulness recognition, degree of stress recognition, degree of life level recognition) have significant effects on home management ability. 2) to find out which variables of sociodemographic variables have significant effects on degree of resourcefulness recognition, of stress recognition, and of life level recognition. 3) to identify the influence of significant variables related to home management ability. Data was analyzed by frequency. percentage, mean , F-test, t-test, Duncan's multiple range test. regression analysis , path analysis pearson's r. x2-test. Major findings are as follows; 1) The level of education (husband , wife)and occupation of husband were variables to have influences on home management ability. 2) a. The level of education (husband, wife) and income were variable to have influences on degree of resourcefulness recognition. b. The employment of home makers. income, and the form of family were variables to have influences on degree of stress recognition. c. The level of education (husband, wife) occupation of husband , income , and duration of marriage were variables to have influences on degree of life level recognition. 3) There were significant relationships between home management ability and degree of resourcefulness recognition and of stress recognition (r=0.13, r=-0.12, p<.05). a. The higher degree of resourcefulness recognition, the higher home management ability (x2=11.17. df=4. p<.05) b. The higher degree of stress recognition, the lower home n=management ability (x2=14.64. df=4. p<.01) 4) The education level of homemakers (β =0.15) and income (β=0.12) were variables to have indirect influences on home management ability through the medium of the degree of resourcefulness recognition (β =0.13) 5) The employment of home makers (β=-0.17) was a variable to have indirect influence on home management ability through the medium of the degree of stress recognition(β=-0.12) 6) the education level of husband (β=0.16) and income (β=0.32) were variables to have direct influence on degree of life level recognition. 7) The degree of life level recognition (β=0.13) and education level of home makers (β=0.17) were variables to have indirect influences on home management ability through the medium of the degree of resourcefulness recognition (β=0.13) 8)The degree of life level recognition (β=-0.22) the employment of home makers(β=-0.17) and the from of family(β=-0.10) were variables to have indirect influences on home management ability through the medium of the degree of stress recognition.

The purpose of this study was to explore the effect of maternal perception of children's temperament on parenting stress. The subjects of this study were 303 mothers of four to six-year-old. Evaluations of Parent and Teacher temperament questionnaire for Children 3-7 years of age(Tomas, Chess, & Kom, 1977)(korean version) was used to measure children's temperament, and PDH(Parenting Daily Hassles) was used to measure maternal perception of parenting stress. Data were analyzed by descriptive analysis, t-test, ANOVA, Peasons's Correlation and multiple regression analysis and Duncan test for post test by SPSS WIN program. The results of this study were as follows; First, the average level of maternal perception of children's temperament was the highest in the category of adaptability and the lowest in the category of threshold of responsiveness. Second, maternal perception of children's temperament was significantly different according to children's sex. Boys were perceived higher than girls for the category of activity level. Third, the degree of daily hassles was explained by adaptability, the quality of mood, and activity level relatively, while the intensity of parenting stress could be predicted orderly by adaptability, threshold of responsiveness, attention span & persistence, regularity, and activity level. Fourth, mother's daily hassles was explained 22% valiance by children's temperament such as adaptability, the quality of mood, and activity level. Future research should be done to identify the interaction of temperamental factors.

This purposes of study are to examine the effect of family related stress and social support on the ways of coping of adolescents and provide a ground necessary to improve it. A survey was conducted on 756 adolescents who were living in Naju. Collected data were analyzed by descriptive statistics, Pearson's correlation, and multiple regression analysis. This study utilized two different models, direct effect model and buffering effect of social support in order to examine the effects of social support on the ways of coping of adolescents. Research findings suggest that the level of coping appeared to be low in general among adolescents. The finding of direct effect model of social support was that mother's support, father's support, sibling's support, lather's grade, mother's grade, and economic level effected the ways of coping of adolescents. But it was not empirically supported that the social support buffered the family related stress on the ways of coping. In other words, the effects of family related stress factor didn't decrease with the increase in the level of social support, however the level of coping increased at a mercy of the age and economic level. Finally, this paper attempted to provide some alternatives to effectively improve the ways of coping among adolescents based on empirical findings.

The main purpose of this study was to examine the mediating roles of mothers' psychological well-being and support/control in the relationship between maternal child-related stress and adolescents' school adjustment. Participants were 389 3rd grade middle school students and their mothers. Mothers completed questionnaires about child-related stress and psychological well-being. Adolescents completed scales of maternal controlling/supportive parenting and school adjustment. Results indicated that a direct effect of mothers' child-related stress on adolescents' school adjustment was not significant. However, mothers' psychological well-being and support/control mediated the relations between child-related stress and adolescents' school adjustment. A higher level of child-related stress in mothers was associated with a lower level of psychological well-being, followed by a lower level of adolescents' school adjustment. Mothers who reported a higher level of child-related stress tended to be less supportive and more controlling, which led to a lower level of school adjustment. These findings suggest the need for considering both maternal characteristics and parenting in explaining adolescents' school adjustment.

Many studies have shown that the parents of developmentally disabled children are adversely affected by the experience of raising a child of this type. However, the range of reactions to parenting a handicapped child is quite varied and is presumably affected by a wide variety of variables. This study examined a number of demographic and psychosocial variables to determine which particular combination could best predict the current level of stress and coping behavior of mothers. Among predictor variables, marital satisfaction and dysfunctional attitude are variables that I am particularly interested in which can mediate parental stress. Five variables are found to be related to the stress of mothers, that is, level of disability, level of needed help, marital satisfaction, type of disability, father's education level. Also variables that affect four different types of stress (which are four factors of QRS-F) are analysed and the results presented. Among these variables, some are pre-determined and some are intervenable. We should make an effort to make changes in those intervenable variables such as marital satisfaction, beliefs and attitude about disability, and level of needed help. In future research we need to search and clarify the beliefs and attitude that help mothers adjust to a life with a disabled child. Also governmental support and policy making to reduce the burden of these mothers should be accompanied as well.

Eight-week old perennial ryegrass (Lolium perenne L. cv. Reveille) plants were exposed to different NO3-concentrations or osmotic stress with NaCI. Previously labeled "N was chased during 14 days of non-labeled'NO3 feeding in order to investigate NO3 metabolism in relation to osmoregulation. The short termmeasurement of osmotic potential showed that the extemal concentration of Nos- had not great effect on theosmotic potential, but that osmotic adjustment was observed in NaCl-treated plants. Total uptake of NO 3 - waslargely increased by increasing supply level of NO3 while it was depressed by exposing to osmotic stress.Nitrate reduction increased to more than 29% by increasing extemal NO,- concentration from 1 mM to 10mM. When osmotically stressed with NaCI, nitrate reduction was depressed to about 37% as compared to thecontrol. The decrease in translocation of reduced N into leaves was also observed in NaCl exposed plants. Inthe medium exposed to 10 mM NO,., osmotic contribution of nitrate to cumulative osmotic potential wasdecreased, and it was osmotically compensated with soluble carbohydrate. When osmotically stressed withNaC1, the contribution of chloride was much higher than that of nitrate. The present data indicate that N03-in plant tissues, factually affected by the assimilation of this ion, plays an active role in osmotic regulation incorrelation with other osmotica such carbohydrate and chloride.(Key words : Nitrate metabolism, Osmotic stress, Nitrate supply level, Osmoregulation)ate supply level, Osmoregulation)

Statement of problem: Standard type of ITI solid implant model in the 6.2mm thick jaw bone was axisymmetrically modelled for finite element stress analyses. Purpose: Primary objective was to investigate the influences or the characteristic design configuration of the ITI solid implant model on the bone stress with the course of osseointegration process at the bone/implant interfaces. To simulate the characteristics of the osseointegration process, five different stages of the bone/implant interface model were implemented. As load conditions, vertical load of 50N was taken into consideration. Bone at the cervical region of implant was the areas of concern where the higher level of stress were likely to take place. Results: The results indicated that rather slightly different stress level could be obtained as a function of the osseointegration conditions. Conclusion: Under vertical load, the lower level of stress was observed at the cervical cortical bone in the initial and final stages of osseointegration. Relatively higher stress level, however, was observed during the transitional stages where the osseointegration at the cancellous bone interface were yet to fully develop.

Objectives: The purpose of the study is to investigate the correlation between stress and oral health in some high school students. Methods: The subjects were 224 students from three high schools in Daejeon, Daecheon, and Incheon. from November to December, 2015. A self-reported questionnaire was filled out from November to December, 2015. The questionnaire consisted of general characteristics of the subjects, awareness toward stress, stress-coping pattern, oral health-related quality of life and oral health care. Data were analyzed by SPSS 18.0 program. Results: In the analysis of academic stress level by the general characteristics and stress level, higher stress group showed higher experience in stress expectation(high group 16.43, subgroup 9.21), internal stress(high group 13.97, subgroup 6.16), expression type stress(high 10.06, sub-4.95). The higher stress group had emotional stress management in stress-coping pattern and less experience in difficulty of tooth brushing, chewing discomfort, and oral health-related quality of life management(p<0.001). Conclusions: The stress had a negative impact on the oral health related quality of life. The high school students should be able to manage the physical and mental stress. It is necessary to provide the continuous oral health care management against the stress by the dental hygienists.

To investigated the effects of Kwibi-tang water extract (KBT) on the non-specific immune response in C57BL/6 mice stressed by immobilization, we evaluated the changes in the contents of serum histamine and corticosterone and the phagocytic activity of macrophages. The level of serum histamine and corticosterone was determined with spectrofluorometer. The cell viability was determined by a MTT assay method. The subpolpulation of lymphocytes was determined by a flow cytometry. The phagocytic activity was determined with luminometer. KBT decreased the serum level of histamine and corticosterone increased by immobilization stress. Also, KBT enhanced the phagocytic activity and decreased the level of nitric oxde in murine peritoneal macrophages decreased by immobilization stress. These results indicate that KBT may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of the non-specific immune response.
