Backgoround: This study aimed to examine the influence of anxiety sensitivity on task performance and physiological stress response, and to assess the effect of depression in this process for the youth population. Methods: We presented participants with an uncontrollable stress situation where they were required to perform mental arithmetic, based on the Montreal Imaging Stress Task (MIST). A total of 29 participants volunteered for this study. They completed the Anxiety Sensitivity Index-Revised and Patient Health Questionnaire-9 to measure their levels of anxiety sensitivity and depression. Two saliva samples, one before and one after the experiment, were collected to assess the change in cortisol levels as an index of physiological stress response. Results: Participants with high anxiety sensitivity showed lower performance on the mental arithmetic tasks and a significant increase in a salivary cortisol level, compared to those with low anxiety sensitivity. Furthermore, cortisol levels showed a remarkable increase where high anxiety sensitivity was coupled with depressed mood. In other hands, the levels of cortisol remained unchanged despite high anxiety sensitivity with low depressed mood. Conclusions: Our results confirm that the interaction between anxiety sensitivity and depression affects participants' task performance and stress response, as measured through behavioral tasks and physiological data with self-report indices. Also, through the physiological data, we examined that those who have a high level of anxiety sensitivity showed maladaptive responses under high stressful situation.

Objectives: This study was designed to evaluate difference of the alexithymia between panic patients and normal controls by examination of the relationships between different components of the alexithymia construct and level of anxiety and depression in panic patients and normal controls. Methods The subjects were 167 patients who met DSM-IV criteria for panic disorder and 110 normal controls. They drew up symptom checklists and self-rating scales, and were measured by Anxiety Disorders Interview Schedule-Panic attack & Agoraphobia(ADIS-P & A), Korean version of Toronto Alexithymia Scale (TAS-20K), Spielberger State-Trait Anxiety Inventory-State & Trait (STAI-S & T), Beck Depression Inventory (BDI), and Revised Anxiety Sensitivity Index (ASI-R). For statistical analysis, we performed t-test to compare the sociodemographic characteristics and the scores of self reported scales between panic patients and normal controls. Pearson correlation was performed between TAS-20K and it's subfactors, STAI-S & T, ASI-R and BDI in panic patients and normal controls. And stepwise multiple regression analysis was preformed to explain results of correlation analysis for alexithymia. Results: The panic patients reported more significant alexithymic (p<0.001), more difficulty identifying feeling (p<0.001) and describing feeling (p=0.001) than normal controls. Futhermore, panic patients were more significant anxious, sensitive to anxious feeling and depressive than normal controls. Moreover, the alexithymia of panic patients was explained by trait-anxiety $({\Delta}R^2=0.255)$ and anxiety sensitivity $({\Delta}R^2=0.062)$, that of normal controls was predicted by depression $({\Delta}R^2=0.144)$ and anxiety sensitivity $({\Delta}R^2=0.033)$ Conclusion: The panic patients reported more anxious and sensitive to anxious feeling, and these symptoms predict alexithymia in panic patients. However, the alexithymia of normal controls was explained by depression more than anxiety sensitivity, and such a result isn't consistent with previous studies and this may be mainly due to difference of the homogeneity in object of the studies.

The purpose of this study is to verify the mediating effect of rejection sensitivity and relationship addiction in the relationship between abandonment anxiety and psychological dating violence. For this purpose, data of 400 adult were collected and analyzed, and the structural equations were used to verify them. The measurement tools were the Abandonment Anxiety Scale, the Rejection Sensitivity Questionnaire Scale, Relationship Addiction Questionnaire-30 and Psychological Dating Violence Scale, which were the Revised Conflict Tactics Scales-2 and Appraisal of Partner Control Scale. The results of the study are as follows: First, there was a significant corelation among abandonment anxiety, rejection sensitivity, relationship addiction, and psychological dating violence. Second, there was no direct effect on the relationship between abandonment anxiety and psychological dating violence, but it had an effect on psychological dating violence by double mediating rejection sensitivity and relationship addiction. Based on these results, we confirmed the psychological path that abandonment anxiety affects psychological dating violence, and discussed the need for therapeutic intervention and educational approach in negative interpersonal patterns that are not visible.

The purpose of the present study was to investigate the influence of rejection sensitivity on aggression and to determine the mediating role of self-esteem level and its stability. Data based on self-report questionnaires from a sample of 312(N=312) undergraduate and graduate students were analyzed using the SPSS 22.0, and the Amos 18.0. Results from the structural equation modeling indicated that rejection sensitivity had a negative impact on self-esteem level and a positive impact on self-esteem instability. Self-esteem level had a negative impact on aggression. Self-esteem instability had a positive impact on aggression. The effect of rejection sensitivity on aggression was fully mediated by self-esteem level and instability. Current findings add to the extent literature on the influence of rejection sensitivity on self-esteem level, self-esteem instability, and aggression. Implications of the present study, limitations of current study as well as suggestions for future study were also included in the discussion.

여러 가지 형태의 연소 불안정성 중에서 50-500Hz 사이에서 발생되며 길이방향 모드(longitudinal mode)로 특징이 있는 저주파수 불안정성이 램제트 혹은 재연소기(Afterburner)의 연소 불안정성에서 가장 중요한 것이라고 여겨진다. 본 논문에서는 램제트 흑은 재연소기에서 일어날 수 있는 길이 방향의 연소 불안정성을 Modal 해석법을 사용하여 수학적인 모델로 만들었다. 특히 이 모델의 선형형태는 어떤 형태든지 선형 속도에 민감한 Burning rate 모델을 사용할 수가 있어서 보다 포괄적인 형태로 만들어져 있으며, 이 모델을 이용하여 여러 가지 연소 형상과 불완전 연소 응답 등을 연구할 수 있다. 본 논문에서는 실제 연소 형상과 유사한 삼각형 모양의 연소 형상을 사용하여 기존의 다른 모델들과 비교 분석하였다.

The purpose of the present study was to investigate empirically the relationship among self-image, depression, anxiety, and social sensitivity in adolescents. 1602 normal adolescents(697 males and 905 females) responded to self report scales-Offer Self-Image Questionnaire-Revised, 3 subscales of Symptom Checklist-90-Revised. The data were analyzed with ANOVA and LISREL to examine the effect of self-image on depression, anxiety, and social sensitivity, and to test the relationship among the above 4 variables. Adolescents with low self-image showed significantly higher scores in the scales of depression, anxiety, and social sensitivity than did adolescents with high self-image. The result of LISREL showed that the low self-image leads to the emotional state of depression and anxiety, and those of depression and anxiety lead to the increase of social sensitivity, suggesting that self-image has a direct effect on depression and anxiety, and has a direct effect on social sensitivity in adolescent. These results were discussed in terms of implications for the prevention and treatment of adolescent social phobia.

This study aimed to examine the effects of rejection sensitivity on depression and anxiety, and the moderating effects of school violence victimization experiences on the relationships between rejection sensitivity and both anxiety and depression. Based on the results, we suggested a method of screening soldiers at high risk of depression and anxiety and interventions for their psychological adaptation. The data about anxiety, depression, rejection sensitivity, and school violence victimization experiences was collected from 126 airmen in S city, South Korea. To test the moderation effects, multiple regression analyses were conducted in which the rejection sensitivity, anxiety, school violence victimization experiences and their interaction terms were hierarchically entered. The moderation of school violence victimization experiences was found in the relationship between rejection sensitivity and school violence victimization experiences. The specific interaction patterns in each of these significant interaction effects were examined. Finally, the importance of school violence victimization experiences as a high-risk factor in army life and the clinical implication of these findings were discussed.

People who were exposed to chronic interpersonal traumas in their early life consistently demonstrate complex psychological disturbances and many of them meet the criteria for proposed diagnosis of complex posttraumatic stress disorder (complx PTSD). The author reports a case of the successful sequential integrative treatment mainly composed of eye movement desensitization and reprocessing (EMDR) in a complex PTSD patient. The patient did not respond to the previous treatment with psychotropic medications and supportive psychotherapy. Twelve sessions of EMDR and three sessions of supportive psychotherapy were done for the patient. Psychological assessments were performed before starting the treatment and a week after completing the treatment. After the treatment, the patient improved on all the psychological scales and behavioral measures. This case suggests that the sequential integrative treatment mainly composed of EMDR may be effective for complex PTSD patients.
