The purpose of this study is to investigate how depression, death anxiety, and social support can exert influence on the psychological well-being of elderly living alone through a parameter of resilience. A survey was conducted involving 988 elderly over the age of 65 living alone in the Daejeon metropolitan area and Chungcheongnam-do and the data were analyzed using structure equation model. The results were as follows. First, in the measurement of variables according to demographic characteristics, depression showed significant differences depending on gender, level of education, health, and financial condition, while death anxiety differed depending on gender, and level of education. Social support was significantly different by gender, age, level of education, region, health, and financial condition. The level of resilience was significantly different by gender, age, level of education, health, and financial condition. Psychological well-being varied according to gender, level of education, health, and financial condition. Second, the effects of depression, death anxiety and social support on psychological well-being were examined. It was found that depression had a negative influence and social support had a positive impact while death anxiety showed no influence. Third, with regard to the effects of depression, death anxiety, social support on resilience, depression was found having negative influence, whereas social support having positive influence. Forth, psychological well-being was positively affected by resilience. Also, through the mediated pathway of resilience, their psychological well-being seemed to totally improve when the negative factors were reduced and the positive ones promoted. This study may have some significance in reference to examine the factors affecting the psychological well-being of elderly living alone and to develop social welfare service programs and policies in the field.

We investigated the influence of negative emotion such as state-trait anxiety and depression and working memory (WM) on Foreign Language Vocabulary Learning (FLVL) of South Korean university students. Also, its implications for developing contents for FLVL were discerned. To do so, state-trait anxiety and depression inventories as well as four kinds of WM test were performed for 132 undergraduate students. Participants also had two semantic learning sessions for Swahili words. The mean scores of negative emotions were normal level. The results of structural equation modeling (SEM) showed that there was no effect of negative emotion on FLVL, while direct effects of the negative emotion on WM and the WM on FLVL were significant. Such results suggested that FLVL would be weakened, with the result that WM had been impaired by negative emotions. These outcomes suggested that when developing FLVL content for university students, it is necessary to consider the negative emotions of foreign language learners and to develop the contents for FLVL in the light of WM load.

Objectives: The psychophysiologic response pattern between healthy subjects and patients with generalized anxiety disorder, and the relationship among anxiety rating scales and those patterns in patients were examined. Methods: Twenty-three patients with generalized anxiety disorder(AD) and 23 healthy subjects were evaluated by Hamilton Rating Scale for Anxiety(HRSA) and State-Trait Anxiety Inventory before baseline stressful tasks. Subjective Units of Distress were evaluated just before baseline period, immediately after stressful tasks, at the end of the entire procedure, and psychophysiologic measures, i.e., skin temperature(ST), electromyographic activity(EMG), heart rate(HR), electrodermal response(EDR) during baseline & rest and during two psychologically stressful tasks (mental arithmetic, TM; talk about a stressful event, TT) were also evaluated. Results: 1) AD group showed significantly higher EMG level during rest after stressful tasks and higher HR level during all period except TM compared to control group. 2) AD group showed lower change in the startle response(SR) of ST, in the SR & the recovery response(RR) of EMG during TM, and in the RR of EDR immediately after TM than control group. AD group showed that the RR of EDR was significantly lower than the SR during stressful tasks. 3) We found that there was significantly negative correlation between state anxiety and the RR of EDR after TT in AD group. We also found that there were significantly positive correlations between HRSA score and the SRs of EDR during stressful tasks, and between state anxiety and the SR of EDR during TT. Conclusion: Our results suggest that patients with generalized anxiety disorder show higher autonomic arousal than healthy subjects and decreased physiologic flexibility or reduced autonomic flexibility.

Objective : This study aimed to investigate the characteristics of the early maladaptive schemas in patients with panic disorder. Methods : Patients (n=35) included people who had met the DSM-IV-TR criteria for panic disorder. The normal control group (n=35) were those people who had no psychiatric disorder and had never experienced panic attack. The early maladaptive schemas and the severity of depression and anxiety were assessed by the Young Schema Questionnaire Short-form (YSQ-SF), the Beck Depression Inventory (BDI), and the Spielberger State-Trait Anxiety Inventory (STAI). Results : The scores on the STAI-S, STAI-T, and BDI were significantly higher in the patient group. Compared to the control group, the scores of vulnerability to harm and illness, and abandonment/instability schemas were significantly higher in the patient group. In the patient group, defectiveness/shame and subjugation schemas were found to predict BDI, dependent/incompetence, abandonment/instability schemas were found to predict STAI-S, and vulnerability to harm and illness, and abandonment/instability schemas were found to predict STAI-T. In normal controls, failure and insufficient self-control/self-discipline, failure, and emotion inhibition schemas were found to predict BDI, STAI-T, and STAI-S. Conclusions : Vulnerability to harm and illness and abandonment/instability schemas may be characteristic schema in patients with panic disorder.

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.

This study was conducted to find out the difference between aging anxiety and self-efficacy according to the general characteristics of the elderly in the community and to find out the correlation between aging anxiety and self-efficacy. From April 2019 to August 2019, 284 responses were used in the final analysis, focusing on senior citizens' health centers, welfare centers for senior citizens, health centers, and senior citizen centers in Gwangju and South Jeolla Province, and the survey was conducted using an aging anxiety scale and a self-efficacy scale. Studies have shown that aging anxiety has shown statistically significant differences in age, economic level, health condition, and present concern, and self-efficacy has shown statistically significant differences in age, academic background, religion, economic level and health status. The higher the age anxiety, the lower the self-efficacy. It is thought that it can be used to establish specific strategic measures for successful aging that can keep healthy for a long time and maintain a safe life.

The turbopump of the liquid rocket engine adapts an inducer to minimize the cavitation due to the variations of the propellants supply condition. However, the inducer introduces cavitation instabilities which are well-known problems in the engine development. In this paper, operational characteristics by the cavitation instabilities are analyzed and the reliability of the engine is checked when the first stage engine of the KSLV-II is tested at the low inlet pressure conditions. The characteristic frequencies representing the cavitation instabilities of the LOx pump are clearly found in various high frequency sensor signals around the entire engine in addition to the LOx and fuel pump.

The aim of this study was to identity the death anxiety of elderly people living alone, and the factors that affect their death anxiety. The subjects did not have an impaired cognitive function, and were from one Chungcheongnamdo 2 district in the elderly University. The subjects were 187 elderly people over the age of 65 living alone in the district. The character, communication, and data was collected from February, 2014 to 2 May, 2015 and analyzed using the SPSS 18 program. The death anxiety whole point of elderly people living alone was 2.94 (${\pm}0.32$); it was 3.06 (${\pm}0.32$) points according to the sub-region 'death process anxiety', 2.88 (${\pm}0.51$) points according to 'after-death anxiety', and 2.75 (${\pm}0.43$) points according to 'presence loss anxiety'. The factors affecting the death anxiety were economic status, depression, and spiritual wellbeing. Economic status (${\beta}=-.36$, p= .000) had the largest effect with an overall explanatory power of 20.3%. Therefore, for the death anxiety of elderly people living alone, life needs to be strengthened through social security systems with intervention programs to improve the quality of depression and spiritual wellbeing.

Test situations are relatively specific and are experienced by everyone. The major purposes of this overview are to review the current concepts and theories of test anxiety and based on this review to suggest future directions in test anxiety theory and research. Test anxiety can be explained in terms of drive-oriented approach. trait-state anxiety theory, cognitive theory, cognitive and emotional approach, and psychodynamic theory. Usually, high test-anxious students keep the following characteristics : 1) The test situation is seen as difficult, challenging and threatening. 2) The individual sees himself as ineffective, and inadequate in handling the task at hand. 3) The individual focuses on undesirable consequences of personal inadequacy. 4) Self-deprecatory preoccupations are strong and interfere or compete with task-relevant cognitive activity. 5) The individual expects and anticipates failure and loss of regard by others. Future directions in test anxiety research should be focused to elucidate the nature and construct of test anxiety and the etiological factors of test anxiety by conducting research on the relationship between parental or social attitude and test anxiety. The effects of test anxiety on memory, attention, and cue utilization should be performed to elucidate the relationship between test anxiety and performance.
