This is a pilot study on rural women's psychological trap to define some obstacles to self directed learning. During few decades, according to major crop of each farm household has shifted from rice to other crops like as vegetables, fruits, horticultures, livestock, etc., women's role or labor sharing of women in farming has been also increased. Although women are important human resources, till now, there is no a research or an approach to rural woman on the view of individual human being. Therefore this study will contribute to understand woman's behavior or attitudes based on psychological description at each person's experiences. For this study, the data was collected from 23 women leaders who participated in a training course in 2005, through the scale of Jeffrey E. Young & Janet S. Klosko which was developed to improvement of one's repetitious behavior based on cognitive psychological care. It was categorized into 11types of psychological trap of one person, named as follows; (1) trap of being deserted by someone (2) trap of disbelief and being ill-treated (3) trap of weakness (4) trap of dependence (5) trap of emotional deprivation (6) trap of feelings of alienation among society (7) trap of deficiency (8) trap of anxiety to failure (9) trap of subordination (10) trap of the merciless standard by self-estimation (11) trap of the sense of privilege. From the data, the average age of subjects was 52.8years old, and the educational back of subjects was higher than general rural women. In both of the trap of weakness and the trap of the merciless standard by self-estimation, the ratio of over and 4 point score of 6 points was 71.4% and 76.2%. It means most of subjects have experienced fear of unexpected calamity(trap of weakness), and mental press hard for efforts to meet one's ideal standard(trap of the merciless standard by self-estimation). Especially the trap of the merciless standard by self-estimation may have relation with rural women's over burden from farming and local society activities.

This study used a non equivalent quasi-experimental design. Aromatherapy was the inhalation of blending oils with lavender, eucalyptus, peppermint for 3 weeks. As the estimation for the physiological aspect, the visual analogy scale (VAS) for the pain level, blood pressure and pulse rate were measured. Also, as the estimation for the psychological aspect, Sleep of Snyder-Halpern & Verra, anxiety of Spielbeger and depression of Beck were used. The data were analyzed by SAS program using $x^2$ test, Fisher's exact test, Cronbach ${\alpha}$ and t-test. The results of this study were as follows. Pain level(p=0.001), state anxiety(p=0.018), trait anxiety(p=0.002), and depression(p<0.001) improved significantly in the experimental group. Also, there was significant difference between the experimental group and the control group on the depression(p=0.012). Aromatherapy was effective in physiological and psychological therapy.

Purpose: The purpose of this study was to determine whether psychological distress is an independent risk factor for recurrent cardiac events in patients with coronary artery disease (CAD). Methods: A prospective cohort of studies that measured psychological distress and the incidence of recurrent cardiac events in the adult population were included. Three computerized databases were assessed (PubMed, CINAHL, and PSYCINFO). Meta-analysis was conducted using a random-effects model to determine summary estimates of risks of major recurrent cardiac events associated with each psychological distress. Of 506 publications identified, 33 met inclusion criteria, and 24 studies were used to estimate effect size of psychological distress on recurrent cardiac events. Results: Mean number in the research sample was 736 and mean time of follow-up was 4.0 years. Depression, anxiety, anger, and hostility as psychological factors were studied. According to estimation of effect size using random model effect, depression (OR=1.39, 95% CI: 1.22-1.57), anxiety (OR=1.22, 95% CI: 0.96-1.56), and anger/hostility (OR=1.29, 95% CI: 1.07-1.57) CAD patients in significantly increased risk for recurrent cardiac events. Conclusion: Finding suggests that psychological distress in forms of depression, anxiety, anger, and hostility impact unfavorably on recurrent cardiac events in CAD patients.

The value of housewife occupation is likely to be underestimated because of its invisibility and myth. This study was performed to investigate social meaning of housewife occupation in the modern society using concept of psychological benefit and cost of full-time housewife. Subjectively even if housewife occupation was perceived as benefit in some aspects full-time housewife was not considered as favorable status but as costly one compared to employed housewife. The perceptions of benefit and cost of housewife occupation were different from some characteristics of housewife and related to the content of works. Finally the estimation of housewife occupation was more influenced by psychological variables rather than conditions and situations of housewife. these results suggested that psychological meaning of housewife occupation is important to understand issues related to the housewife.

We investigated event-related potentials (ERPs) to estimate the accuracy of eyewitness memories. Participants watched videos of vehicles being driven dangerously, from an anti-impaired driving initiative. The four-letter license plates of the vehicles were the target stimuli. Random numbers were presented while participants attempted to identify the license plate letters, and electroencephalograms were recorded. There was a significant difference in activity 300-500 milliseconds after stimulus onset, between target stimuli and random numbers. This finding contributes to establishing an eyewitness recognition model where different ERP components may reflect more explicit memory that is dissociable from recollection.

This dissertation studied the psychological cost, which converted the mental pain suffered by the victim of a traffic accident and his/her family, friends and people around him/her into social costs. Three methodologies - Choice Experiments, Direct Question and Dichotomous Choice Question - were used to design questionnaires, and models were built for each questionnaire design method. When building models, a logit model was used, which is used most frequently in probabilistic choice model. And the tobitmodel was used to make direct questionnaires. When verifying these models, although there were some differences in each model, suitability of most models and credibility of each coefficient were meaningful around the credibility level of 95%. According to the analysis, domestic psychological cost produced through the assessment model of psychological cost was 15.63 million won per person or 5.1 trillion in total, assuming 37.1% of total traffic accident cost.
