Abstract PDF
The purpose of this study was to explore the determinants of subjective well-being among Korean Adolescents. Specially, it tried to find out how socio-demographic, health, and delinquent behavior factors influence on their level of subjective well-being. This study used the 2009 Korean Youth Health Risk Behavior On-line Survey data. It conducted a secondary data analysis of 75,006 cases. It conducted frequency analysis, t-test, F-test, correlation analysis and multiple regression analysis. Although various independent variables influenced on their level of subjective well-being, gender, grade, living with parents, educational background of father, economic status, academic record, level of stress, level of depression, overall health status, internet addiction, alcohol use, smoking and drug use were key determinants of their level of subjective well-being among Korean Adolescents. Findings may be used for realizing the key factors of subjective well-being and developing new promising strategies to enhance the subjective well-being among Korean Adolescents.

Abstract PDF
This study investigates natural clusters of people in terms of General Procrastination and the sub-factors of Active Procrastination (outcome satisfaction, preference for pressure, intentional decisions to procrastinate, and the ability to meet deadlines) and what differenes are observed among the identified clusters of subjects with respect to problem-solving styles. The results of cluster analysis conducted on a sample of 359 undergraduates have led us to identify three clusters of students: the Non-Procrastination group, the Passive-Procrastination group, and the Active-Procrastination group. Their differences in problem-solving styles have turned out. The Non-Procrastination group has demonstrated better functioning in problem situations than two procrastination groups. The Active-Procrastination group in regarding problem situations felt less helpless, more creative style, more confidence and more likely to use an approach style than Passive-Procrastination group.

Abstract PDF
The purpose of this study is to explore the effects of positive psychotherapy on depression, parenting efficacy, and parenting stress in mothers of children with developmental disabilities. Total 20 mothers who want to participate in this positive psychotherapy program selected through kindergartens and welfare center for disabled children and organization for their parents located in J city. After these 20 mothers were randomly assigned to 10 in positive psychotherapy group and 10 in the control group, we got agreements in mothers who participated in positive psychotherapy group. Positive psychotherapy program was administered for 8 session. However, 1 mother were dropped out at initial session in treatment group and 1 mother in control group were dropped out too, because we couldn't her get post-test questionnaires. So, we administered pre-test, post-test, 4 weeks follow-up test to mothers of each group. As a result, the results of this study were as follows: depression, parenting stress of treatment group were decrease more than those of the control group, and these effects still maintained at follow-up period. Also, parenting efficacy was increased in treatment group, and this effect still maintained at follow-up period. Finally, the implications and the limitations of this study, and the suggestions for future study were also discussed. (Korean J Str Res 2013;21: 0∼107)

Abstract PDF
The purpose of the this study was to explore the effects of the Anger Control Program on anger, interpersonal relation and self-esteem for people with Mental Disability in rehabilitation center. The State-Trait Anger Expression Inventory (STAEI-K), Relationship Change Scale, and Self-esteem Scale were used for screening in pre-test. 11 people who have a high score in anger expression level, and low score in Relationship Change Scale and Self-esteem Scale participated in this study. Then, participants were assigned to anger control program group (n=5) or control group (n=6). The anger control program for participants was administered for 10 sessions in 2 months. Anger, interpersonal relation, and self-esteem were assessed at pre-test, post-test, 1-month follow-up periods. The results of this study were that scores of anger expression in the anger control program group were significantly decreased more than those in the control group, and scores of interpersonal relation and self-esteem in the anger control program group were significantly increased more than those in the control group. However, changes were not maintained at follow-up assessment. Finally, the implications and limitations of this study as well as suggestions for further research were discussed.

Abstract PDF
The purpose of this study was to identify the relationship of family function, self esteem and stress in adolescents. Data were collected from 406 adolescents and analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson correlation coefficients and stepwise multiple regression with the SPSS 18.0 program. Stress differed according to gender, grade, parent relationship satisfaction. Family function and self esteem had a significant negative correlation with stress. Stepwise multiple regression analysis showed total family function, emotional reactivity, communication in family function, self esteem, gender (female), grade (3rd) explained 30.4% of the total variance in stress. The findings indicate that family function and self esteem have an influence on stress. We need to develop and provide nursing intervention programs to prevent and manage adolescent's stress problems and include the family in these programs. (Korean J Str Res 2013;21: 0∼129)

Abstract PDF
This study purpose to understand job stress experienced by nurses and doctors and explain the nature and structure of their job stress-coping. In-depth interviews of 14 participants were conducted to collect the data. The interviews were recorded and then transcribed. The data analysis was done by Colaizzi (1978) method. The job stress experienced by health care professionals was divided into the following five categories: 1) Confronting Burdensome Atmonsphere, 2) Being Likely to Remain Unchanged Reality, 3) Pressure from Both Oneself and Others 4) Efforts for Overcome 5) Wish for Better Work Environment. This research has significance for laying the foundation required to develop a job stress intervention model for health care professionals by understanding the nature and structure of job stress-coping experienced by nurses and doctors through an in-depth analysis of their job stress-coping experiences.

Abstract PDF
Traumatic brain injury (TBI) induces many neuropsychiatric disorders, and memory loss is the most frequent symptom of TBI. In the present study, we investigated the effects of treadmill exercise on the short-term memory in relation with cell proliferation in the hippocampus following TBI in rats. The animals were randomly divided into four groups (N=10 in each group): sham-operation group, sham-operation and treadmill exercise group, TBI-induction group, and TBI-induction and treadmill exercise group. TBI was induced by an electromagnetic-controlled cortical impact. The animals in the treadmill exercise group were forced to run on the treadmill machine for 30 min once daily, for ten consecutive days. Induction of TBI deteriorated short-term memory and inhibited cell proliferation with suppressing brain-derived neurotrophic factor (BDNF) expression in the hippocampus. Treadmill exercise alleviated TBI-induced short-term memory impairment and also increased cell proliferation with enhancing BDNF expression in the hippocampus. The present results revealed that treadmill exercise overcame the TBI-induced memory impairment through enhancing cell proliferation in the hippocampus. Herein, we suggest that treadmill exercise may be used as the useful strategy for the functional recovery following traumatic brain damage. (Korean J Str Res 2013;21: 0∼149)

Abstract PDF
Most of aging-related disorders are related with stress responses in cellular level. In males after middle age, benign prostate hyperplasia (BPH) may cause severe stress by lower urinary tract symptoms. BPH is common androgenic disorder and family history is an etiological factor. As BPH is a multifactorial disease, many genes and cellular pathways may affect the development. Among them, Angiotensinogen (AGT) was regarded important in vascular diseases. AGT also may affect various diseases throughout whole body organs and polymorphisms of AGT may be associated with aging-related morbidities. AGT and stress genes related to AGT signaling may play a role in the pathophysiology of BPH. However, there was no study of BPH regarding the effect of AGT polymorphisms. In this study, we investigated the association of two AGT single nucleotide polymorphisms (SNPs) (rs699 and rs4762) to the development and clinical features of BPH. A total of 221 BPH subjects and 212 control subjects were analyzed. The BPH patient group was divided into two groups based on each of clinical features [prostate volume, peak urinary flow rate (Qmax), serum prostate specific antigen (PSA) level, and international prostate symptom scores (IPSS)] to analyze the effect of the SNPs on each of clinical parameters. In the result, a missense SNP rs699 was only associated to the development of BPH in the genotypes and allele frequencies (p<0.05). In conclusion, we suggest that a missense SNP rs699 of AGT may affect the susceptibility to BPH in the Korean population. (Korean J Str Res 2013;21: 0∼157)

Abstract PDF
Interleukin 13 (IL13) is an immunoregulatory cytokine which may decrease immunologic activity and secretion of proinflammatory cytokines. Cytokines have been known to be modulators of metabolic syndrome and insulin resistance. Polymorphisms of IL13 affect various disease including dermatologic, respiratory diseases, and asthma, which are linked to features of obesity, which is an origin of many stress factors. In this study, we conducted genetic association between IL13 polymorphisms (rs1800925, −1055C/T and rs1881457, −1510A/C) and dyslipidemia, hypertension, and obesity in a total of 265 subjects. The genotype of promoter SNP (rs1800925, −1055C/T) was associated to triglyceride (TG) level (codominant2 model, p=0.021; recessive model, p=0.022) and the genotypes and alleles of another promoter SNP (rs1881457, −1510A/C) were associated to hypertension (codominant2 model, p=0.013; recessive model, p=0.027; log-additive model, p=0.021; allele frequencies, p=0.017) and TG level (codominant2 model, p=0.021; recessive model, p=0.01). In conclusion, promoter polymorphisms (rs1800925 and rs1881457) of IL13 may be associated with the clinical features of metabolic syndrome patients, specially TG and hypertension.
