Anxiety is one of the basic emotions which human experiences across different cultures in the world and it can be observed in mammals. Our understanding of the neurobiology of this emotion has made some advances, even though it has not been completed, with the development and advance in the investigation method including neuroimaging, neurochemical, and genetic approaches. In this article, the neuroanatomical and neurochemical basis of anxiety is reviewed. The amygdaloid complex has been known to playa key role in processing of anxiety or fear. It has extensive afferent and/or efferent connections with cortical and subcortical structures. The mesial temporal structures including hippocampus appear to be involved in acquisition of anxiety and related behaviors. The prefrontal cortical structures appear to play important roles in conscious awareness of anxiety and in modulating anxiety and related behavior. The bed nucleus of the stria terminalis (BNST) is known to playa critical role in unconditioned fear response. The central noradrenergic system and hypothalamo-pituitary-adrenal axis are known to play important roles in modulating and expressing anxiety-related responses. Anxiety has been gathering attentions from many investigators and numerous preclinical and clinical investigations of anxiety and anxiety disorders have been done. In particular, neural plasticity in critical period and the psychobiological factors related to resilience to extreme stress and anxiety are important issues in this field.

Introduction：Test anxiety is a pervasive problem among high school students in Korea. While anxiety in test situations may actually facilitate the performance of some students, more often it is disruptive and leads to performance decrements. Over the past years, many child psychiatrists have become concerned with understanding the nature of test anxiety, but it is not clearly understood yet. In order to understand the nature of test anxiety, the relationship between test anxiety and depression, state anxiety, trait anxiety was examined. In addition, the relationships between the subscores of test anxiety (worry and emotionality) and the subscores of CDI, state anxiety or trait anxiety were examined. Methods：The Test Anxiety Inventory, Chidlren's Depression Inventory, State-Trait Anxiety Inventory were administered to 425 high school students in Seoul. The relationships between test anxiety and other measures were tested using Pearson correlation coefficients and to test the causal ralationship among the variables, regression analysis was performed. Results：The correlation coefficients between test anxiety and depression, state anxiety, trait anxiety were 0.56(p<0.05), 0.75(p<0.05), 0.53(p<0.05) respectively. The correlation coefficients between subscales of test anxiety and depression were all significant. The correlation between subscales of test anxiety and state and trait anxiety were also statistically significant. Conclusions：This study indicates that test anxiety is closely related with depression, state and trait anxiety. In addition, the subscales of test anxiety are significantly related with those of the depression. The correlation coefficients between test anxiety and state-trait anxiety are also statistically significant. Thus, in order to develop the preventive and effective methods for treatment, these psychopathological characteristics should be kept in mind.

In this study of mathematics anxiety, mathematical learning style, and grade in school, 1,264 elementary students completed the Mathematics Anxiety Scale(Lee, 2005) and the Mathematical Learning Style Scale(Yang & Whang, 2005) for elementary school students. Analysis of their responses showed that anxiety about mathematics increased with grade in school. Among sub-factors of mathematics anxiety, the subject itself, learners' attitude, and learning environment increased the anxiety of upper grade students. Motivation, initiative, and regulation styles of learning mathematics were found to be important factors in the mathematics anxiety of elementary school students.

The main purpose of this study was to examine the relationship between marital conflict, parental control, and adolescents' anxiety. The participants were composed of 319 high school $1^{st}$ graders (of which 153 were boys and 165 were girls) from the Seoul area. They completed questionnaires on marital conflict, parental control, and adolescents' anxiety. The data were analyzed by means of Pearson's correlation coefficients and regressions. It was observed that marital conflict (frequency/intensity/resolution/content) was positively correlated with adolescents' anxiety. Parental psychological control was also positively correlated with adolescents' anxiety. However parental behavioral control was negatively correlated with adolescents' anxiety. In addition marital conflict was positively correlated with parental psychological control in contrast with that of behavioral control. It was further found that parental psychological and behavioral control partially mediated the relationship between marital conflict and adolescents' anxiety. These results clearly indicate that parental control plays a crucial role in marital conflict and adolescents' anxiety.

The purpose of this study was to investigate the level of uncertainty and anxiety in families of hospitalized children. Data were collected through self-report questionnaires which were constructed to include parent's perception of uncertainty and state anxiety. The subjects consisted of 126 families of hospitalized children in one university-affiliated hospital in Daegu. The data were analyzed by the SPSS program. The results were as follows; 1. The mean score of uncertainty was 64.70 (Range=31-95). The mean scores of subsets of the uncertainty were followed as: lack of clarity (2.59), unpredictability (2.46), lack of information (2.22) and ambiguity (2.14). 2. The mean score of state anxiety was 47.93 (Range=20-67). 3.The level of uncertainty was positively correlated to the level of state anxiety. 4. The level of anxiety was different depending on their religion and monthly income. The above findings indicated that the level of uncertainty and the state anxiety in families of hospitalized children were positively correlated. Therefore, nursing intervention for reducing uncertainty and anxiety and improving coping method should be provided for families of hospitalized children.

In this article, we review research on how normal personality traits and personality disorder traits may relate to anxiety disorders ; as predisposing factors, 2) as complications, 3) as pathoplastic factors, and 4) as manifestations of common underlying etiologies. Based on current literatures, we draw a conclusion as follows : 1) Normal personality traits such as high neuroticism and low extraversion and personality disorder traits, especially cluster C traits, are at least risk factors for certain anxiety disorders ; 2) Anxiety disorders in early life might influence a later development of personality disorder ; 3) Personality disorder traits may have negative influence on the outcome of anxiety disorders ; 4) Personality and anxiety disorders may be manifestations of common genetic and environmental etiologies.

This study investigated the relationship between mother's verbal confrol modes and children's emotional anxiety. The subjects of this study were 157boys and 144 girls attending elementary schools in Busan. Lee Kyung-Hee's(1993) questionnaire on mother's verval control modes, and Kang's(1986) questionnaire on emotional anxiety were used. The results were as follows: 1) There were significant differences in boys and girls about mother's imperative control mode. and children's emotional anxiety. Boys got the higher scores than the girls in mother's imperative control modes. But Girls got the higher score than the boys in children's emotional anxiety. 2) Only for boys, There were significant correlations between mother's imperative control mode and children's emotional anxiety. 3) Sex variabl and mother's imperative control mode variables were the predictor influencing on children's emotional anxiety. That is, girls shown higher emotional anxiety than boys. And children shown higher imperative control get higher emotional anxiety score.

Objective: The main purpose of this study was to investigate the direct effect of preschoolers' behavioral inhibition and indirect effects through maternal overprotective parenting and autonomy support on preschoolers' anxiety. Methods: A total of 295 preschoolers and their mothers were the subjects of this study. Mothers completed a questionnaire that included measures of their parenting behavior, preschoolers' behavioral inhibition and anxiety. Data were analyzed using structural equation modeling. Results: First, preschoolers' behavioral inhibition had a direct effect on their anxiety. Preschoolers with higher behavioral inhibition displayed higher levels of anxiety. Second, maternal overprotective parenting mediated the relationship between preschoolers' behavioral inhibition and anxiety. Third, maternal autonomy support mediated the relationship between preschoolers' behavioral inhibition and anxiety. Conclusion/Implications: The findings of this study emphasize the importance of reducing maternal overprotective parenting and promoting autonomy support to prevent preschoolers' anxiety. These findings could be used as a foundation for developing parent education programs for mothers with behaviorally inhibited preschoolers.

This study was to investigate 1) the correlation of serum Ca, with depression and anxiety ; and 2) the effect of Ca intake on those symptoms. The subjects were three females and two males who were 53-66 years old with the severe subjective symptoms of depression and anxiety. They have taken more than twice Ca of RDA(recommended dietary allowances for Koreans) daily for 6 months(dietary treatment). The prestudy Ca intake of the subjects was low: 60% of RDA for Koreans. Their serum Ca concentration was also low: 6.67 $\pm$ 0.15mg/d1 before the dietary treatment. They expressed severs depression and anxiety, with high self scores in a psychological test. Their serum Ca concentration increased to 8.32 $\pm$ 0.17mg/dl after six months of dietary treatment, while the symptoms of depression and anxiety decreased significantly after two months and nearly disappeared after six months. This result seemed to be an effect of the dietary high Ca intake. Serum Ca and the psychological states of depression and anxiety correlated negatively, and the coefficients of determination were high in the results of linear regression analysis of depression and anxiety by serum Ca. Therefore the serum Ca concentration could be a good marker to predict depression or anxiety relatively well. The continuous high Ca intake could decrease the probability of developing depression or anxiety and mitigate their symptoms because serum Ca concentration increased, while the state of depression and anxiety decreased with the increased Ca intake.
