The purpose of this study was to examine the relationships between ego- resilience and stress coping styles of adolescents. The study also tried to identify differences on stress coping styles based on the level of ego- resilience of adolescents. Ego-resilience showed positive correlations with problem-focused and social support seeking coping styles and a negative correlation with an emotion-focused coping style. Canonical Correlation analysis revealed that self-confidence among four sub-domains of ego-resilience made the most outstanding contributions in predicting stress coping styles of adolescents. The problem-focused coping style had the highest correlation with ego-resilience among the four coping styles. The group of adolescents who had a higher level of ego-resilience reported more problem-focused and social support-seeking coping styles in stressful situations. The results of this study suggested that development of ego-resilience of adolescents who were in the midst of transitions and adjustment problems was important for effective coping strategies.

Data from the National Longitudinal Study of Youth (NLSY) were used to examine factors related to adolescent behavior problems, smoking, and delinquency. This study focuses particularly on the factors in an adolescent s immediate environment such as family, school, peers, and neighborhood (i.e. the microsystems) for the identification, prevention, and early intervention of adolescent behavior problems, smoking, and delinquent behavior. Both African American and Caucasian American adolescents between the ages of 13 and 17 for whom data were available in the NLSY were included in this study (N=788). Results indicate that delinquent peer pressure and negative attitudes toward school are important determinants of behavior problems, smoking, and delinquency of American adolescents. Differences between African American and Caucasian American adolescents are highlighted.

The purpose of this study was to examine the role of children's characteristics, family environment and child care quality in socio-emotional development of children among dual-worker families. The sample consisted of 138 children aged 5-7 and their parents. Descriptive statistics, t-tests, correlation analysis, one-way ANOVAs, and stepwise regression were used to analyze data. Results showed that there were significant sex differences in children's temperament and popularity. Mother's marital satisfaction had a negative correlation with peer rejection. Low maternal role conflict and child's age had effects on children's self-perception. Moreover, sex and age of the child, mothers' responsive parenting, number of teachers in the classroom were significant predictors for children's peer rejection.

This study is to apply a goal-directed model for ethical consumption behavior and to see which factors influence consumers' boycott intention. We identify factors related to a goal-directed model for consumers, level of ethical consumption tendency, and boycott desire; in addition, factors that affect boycott intentions were also analyzed. The results of this study are as follows. First, consumers' boycott intentions are not high and public intention motivation is relatively low. Second, negative anticipated emotion shows an indirect effect with boycott desire as a mediator. Third, ethical consumption tendency has a significant effect on boycott desire and boycott intention. Therefore, we have to let consumers know that boycott actually shows a consumer's right and that it is also necessary to conduct various ethical consumption education.

To gain maximal benefit in a competitive environment, single-celled bacteria have adopted a community genetic regulatory mechanism, known as quorum sensing (QS). Many bacteria use QS signaling systems to synchronize target gene expression and coordinate biological activities among a local population. N-acylhomoserine lactones (AHLs) are one family of the well-characterized QS signals in Gram-negative bacteria, which regulate a range of important biological functions, including virulence and biofilm formation. Several groups of AHL-degradation enzymes have recently been identified in a range of living organisms, including bacteria and eukaryotes. Expression of these enzymes in AHL-dependent pathogens and transgenic plants efficiently quenches the microbial QS signaling and blocks pathogenic infections. Discovery of these novel quorum quenching enzymes has not only provided a promising means to control bacterial infections, but also presents new challenges to investigate their roles in host organisms and their potential impacts on ecosystems.

Pathogenic bacteria that colonize the human intestinal tract have evolved strategies to overcome acidic conditions when they pass through the gastrointestinal tract. Amino acid-mediated acid resistance systems are effective survival strategies in a stomach that is full of amino acid substrate. The amino acid antiporter, amino acid decarboxylase, and ClC chloride antiporter are all engaged in these systems, and each one plays a role in protecting against or adapting to the acidic environment. The ClC chloride antiporter, a member of the ClC channel family, eliminates negatively charged intracellular chloride ions to avoid inner membrane hyperpolarization as an electrical shunt of the acid resistance system. In this review, we will discuss the structure and function of the prokaryotic ClC chloride antiporter of amino acid-mediated acid resistance system.

The purpose of this study is to increase our understanding of subjective well-being in adolescents and to help improve it by investigating the relationship among adolescents' temperaments, perceived parenting affective attitude and subjective well-being. For this study, the subjects were 354 students from 4 different middle schools in Gwang-ju, Korea. The statistical analysis of the data was conducted by means of the SPSS 21.0 program using Pearson's correlations and hierarchical regression. The results are as follows: First, the temperament and perceived parenting affective attitude were correlated with subjective well-being. Among the temperament traits, novelty seeking and harm avoidance showed negative correlations with subjective well-being, whereas affection, reward dependence and persistence showed positive correlations with subjective well-being. Second, after the mediating effect of perceived affection on subjective well-being was confirmed, three temperament traits, viz. harm avoidance, reward dependence, and persistence, were identified as mediating factors. The conclusion of this study is that adolescents' temperament and perceived parenting affective attitude are related to their subjective well-being and can also predict their subjective well-being. Harm avoidance, reward dependence, and persistence, which are inborn temperaments, affect subjective well-being. Affection, which is a perceived parenting affective attitude trait, affects subjective well-being as a mediation variable. This study also suggests that it is more effective to influence perceived parenting affective attitude, which has growth potential, rather than temperaments which are hard to change.

This study aimed to identify the moderating effect of the father's support on the relationship between the mother's parenting guilt and her parenting behavior. For the goal, the present study 1) analysed the differences in the mother's parenting guilt as the general variables of the mother and child, and 2) examined the main effects and interaction effects between the mother's parenting guilt and her spouse's support on the mother's parenting behavior. The participants of the study were 350 mothers whose infants and toddlers were attending a day-care centers in Gwangju and Jeollanamdo. The summary of this study is as follows. First, the mothers younger than 29 years old reported more parenting guilt than the mothers aged 35 to 39. Also, the working mothers felt more parenting guilt than the unemployed mothers. Second, when the main effect and interaction effects among the mother's parenting guilt, parenting behaviors, and the father's parenting support are analysed, the interaction effects were statistically significant with only rejection control parenting behaviors. The result means that even if the mother feels a lot of parenting guilt, if the father's parenting support is high, her rejection control parenting behaviors tend to appear less. The present study suggests that the father's parenting support plays an important role in the reduction of the mother's negative parenting behaviors.

This research aimed to empirically investigate the effects of satisfaction in Elderly Care Facilities (ECF) and daily stresses of aged people on their depression and self-esteem. Subjects were 271 visitors to 8 ECFs located in Central Korea including Seoul. The data was collected by the survey on them, conducted from March 3 to August 25, 2013. By analyzing the data, we found that the satisfaction with service utilization in ECF can reduce depression, while the satisfaction with medical rehabilitation service may increase depression and that the satisfaction with physical environment can reduce self-esteem. Also, the results showed that the stress related to family relationship has a positive effect on depression and a negative effect on self-esteem. and that the stress concerning residential environment can decrease self-esteem. Depression and self-esteem of the elderly can be predicted by satisfaction in ECFs, but not better than by their daily stresses. Among the predictors of depression and self-esteem, in this study, stress concerning family relationship is the most significant and the strongest.

There are less studies on the adult suicide even though it's steep increase and negative effect on person itself, family and society. The purpose of the present study was to investigate factors that influence on the adult suicide and to categorize it. Using a case-study approach, a total of 61 cases were analyzed. Specifically, on the basis of the stress-vulnerability model, I scrutinized vulnerability factors(classified personal, family-environment, and social-environment factors) and precipitating events(classified personal, interpersonal events) influencing on the adult suicide. As the results of this study, adult suicide classified into 3 types, that is, 'risk type suicide', 'event-response type suicide', 'complex type'. And then I discussed the characteristics of the suicidal types and the method for reduction of adult suicide.
