Objectives : The aim of this study was to investigate the relationship between the norepinephrine(NET) transporter T-182C polymorphism and anxiety-related traits in Korean adolescent females. Methods : One hundred sixty-nine Korean adolescent females were tested for the NET T-182C polymorphism by PCR based methods; anxiety-related traits were evaluated using the anxiety sensitivity index(ASI) and the trait form of the Spielberg State-Trait Anxiety inventory(STAI-T). Results : Scores of anxiety related traits were not different between genotypes. Comparison between T allele carries and non carriers revealed no significant difference. Conclusion : These findings suggest that the NET T-182C polymorphism is not associated with anxiety-related traits in Korean female adolescents.

The purpose of this study was to examine the effect of nursing information on the level of need fulfillment and anxiety of the emergency patient's family members. The quasi-experimental study was designed using a noneqivalent control group non-synchronized design. During the first period, 30 subjects were assigned to the control group and 25 to the experimental group at a late period. The experimental group was provided with nursing information via guide booklet designed by the researcher. The control group received only routine care. Data was collected from January 31 to April 16 in 1996 at the K hospital in Taegu and analysed by chi-square test, t-test, ANOVA and Pearson correlation with SAS program. The instruments used for this study were the Family Needs Scale developed by Jung and the State-Trait Anxiety Inventory developed by Spielberger. The results of this study were summarized as follows : 1. The first hypothesis that the family members who received nursing information will have greater need fulfillment than family members who did not receive nursing information was supported. 2. The second hypothesis that the family members who received nursing information will have lower anxiety level than family members who did not receive nursing information was not supported. 3. The third hypothesis that the more the need of family member of emergency patient was met, the lower the anxiety level, was not supported. In conclusion, it was proved that nursing information about the emergency room provides family members with more need fulfillment, but did not decrease the anxiety level.

Objects：This study investigated whether depression, anxiety and perceived parental rearing patterns of the conduct disorder patients are different from those of the normal control group. The correlations were also assessed between perceived parenting style and depression, anxiety, severity of conduct problems and age at onset of conduct disorder in adolescents with conduct disorder. Methods：Thirty hospitalzed patients who met the DSM-Ⅳ criteria of conduct disorder, and 30 normal control subjects completed self-report questionnaires containing the Children’s Depression Inventory(CDI), the State-Trait Anxiety Inventory for Children(STAIC) and the Parental Bonding Instrument(PBI). Results：In the conduct disorder group, the results were as follows：1) The mean scores of CDI and STAIC-T(Trait) were not significantly different from those of the control group, but STAIC-S (State) showed significantly higher scores. 2) Parenting style was perceved to be less caring and more overprotective than in the control subjects. 3) There were negative correlations between maternal care and CDI and between maternal care and severity of conduct problems. 4) There were positive correlations between maternal overprotection and STAIC-T(Trait). 5) There were no correlations between paternal rearing patterns and depression, anxiety, severity of conduct problems, or age at onset of conduct disorder. Conclusion：We failed to identify depression and anxiety as common comorbid disorders in conduct disorder. Parental rearing patterns are thought to be significantly negativistic in conduct disorder group. It is guessed that less caring and more overprotective rearing style of parents, especially of mothers, could have much influence on depression and anxiety, more severe conduct problems and earlier age at onset of conduct disorder in the adolescents with conduct disorder.

This study is to identify perceptions and response degrees of anxiety for each factor, targeting patients for CT test and analyze the relations between factors. It is to provide scientific fundamental data to reduce anxiety by improving awareness of patients about CT test by analyzing relations between variables. The subjects of this study were surveyed in self-writing type, targeting 263 patients for CT test in the department of radiology at three University hospitals from July to September, 2010. This survey was executed once by a structured self-administered survey type. The targeting patients for CT test of anxiety will investigate for affect. Anxiety by each CT test variables depending on CT test-related features showed independent variable is Expense Responsibility, Economic burden, Sufficient explain, Explain agent, Endoscope, Biopsy, Pre treatment, Previous experience, CT side effect experience, Side effect of contrast medium and dependent variable is physical, Hospital staff, Hospital environment, Socioeconomic These used statistics program SPSS (ver. 13.0). Summarizing the above results of this study, awareness of anxiety and response to it in each variable under CT test appeared significant differences in economic burdens, state anxiety, pre-treatment anxiety, exposure anxiety to radiation, and anxiety of side effect. Therefore, pre-treatment before test and pre-training programs on chemical poison of contrast medium and side effect seem to be able to release patients' anxiety level for CT test. Ways to meditate these anxiety variables and reduce degree of anxiety are needed to be researched more and updated. In addition, impact of patients' economic burdens on CT test anxiety is required to be recognized and solved in society level.

The purpose of this study is to explore effective factors of elderly people's overall death anxiety and sub-dimensions of death anxiety. The subjects were 156 elderly people in S City, Gyeonggi-Do gathered by convenience sampling. This study collected data by interviewing the elderly who agreed to participate in the study and then analyzed it using SPSS 12.0 through descriptive statistics, the t-test, F-test, Sheffe-test, correlation analysis, and multiple regression. The respondents' overall death anxiety score was 2.61(±.47), and 'anxiety in the dying process'(2.94) had the highest points among sub-dimensions. Effective factors of overall level of death anxiety among the elderly were 'age' (β=-.18, p=.015), 'education' (β=-.16, p=.045), and 'economic status' (β=-.26, p=.003). In sub-dimensions, the elderly who were female, relatively young, and had low economic status showed high 'anxiety in the dying process'. As for 'anxiety over what will happen after one's death', the elderly who were relatively young, and had low economic status had high scores. Finally, on 'the loss of existence', the elderly who had poor relationships with their families had high scores.

The purpose of this study was to investigate effect of the economic stress and state-trait anxiety on the periodontal disease in order to prevent the occurrence and progression of periodontal disease. Date were collected from total of 326 subjects in their forties and fifties by using questionnaire and examination of periodontal states during the period from February to November 2011. Results were analyzed by using frequency, t-test, ANOVA and Multiple regression of SPSS ver. 19.0. 1. The economic stress were significant statistically to the higher, medium and low of gingival index (p<0.01). 2. The state-trait anxiety were significant statistically to the higher, medium and low of gingival index (p<0.001), of the pocket depth (p<0.05), of the clinical attachment loss (p<0.05). 3. The gingival index were investigate effect of the higher the economic stress ($\beta$=0.052, p<0.01), the higher the state-trait anxiety ($\beta$=0.052, p<0.01). As a result, this study suggests that the dental clinic institute needs to let the patients with the periodontal disease know about the effects of economic stress and state-trait anxiety. They also necessarily need to implement education program including stress management, economic stress, and state-trait anxiety improvement in order to prevent periodontal disease and to take charge.

Objectives: The purpose of the present study was to investigate the emotional state and personality characteristics of patient with panic disorder. Methods: Twenty patients with panic disorder, 21 patients with somatoform disorder, and 20 normal healthy controls were studied. Korean version of Beck Depression Inventory(BDI), State and Trait Anxiety Inventory(STAI) and Korean standardized edition of Cattell's 16 Personality Factors Questionnaire(16-PF) were used for assessment. Statistically, One-way ANOVA with Scheffe test were used by SPSS/PC for windows. Results: 1) Total score of BDI was higher in the panic group than the somatoform group and normal control group(p<0.001). 2) Total score of state anxiety and trait anxiety in the panic group was higher than the somatoform group and normal control group(p<0.001). 3) In 16 PF, there were no definitely abnormal range of scores. But in first-stratum source traits of 16PF, the panic group was higher than the somatoform group and normal healthy group in O-factor (p<0.01) and Q4-factor(p<0.001). In second-stratum source traits of 16PF, the panic group was higher than the somatoform group in ANX-factor(p<0.05), but lower than normal control group in TOUfactor(p<0.05). 4) There were no differences in the panic subgroup according to sex and cutoff points of BDI score 16 and STAI-T score 54. 5) According to cutoff point of STAI-S score 52, the panic subgroup above 52 was higher than the panic subgroup under 52 in G-factor(p<0.001), Q3-factor(p<0.05) and SUP-factor(p<0.001), but lower in L-factor(p<0.05). Conclusion: These results suggest that emotional state of patients with panic disorder are depressive and anxious as compared with patients with somatoform disorder and normal controls. Patients with panic disorder did not show any abnormal personality characteristics but were more guilt-prone, anxious, emotionally sensitive. We propose that the understanding of panic patients' emotional state and personality characteristics will helpful to treat and manage in patient with panic disorder.
