Objectives : The purpose of this study is to study the personality traits of Sasang constitutions by comparing the profiles of Temperament and Character Inventory (TCI) and Eysenck Personality Questionnaire (EPQ). Methods : A total of 110 healthy people (20 to 40 years old), except for 2 Taeyangin (TY type), were analyzed; 45 Taeeumin (TE type), 32 Soyangin (SY type), and 31 Soeumin (SE type). A Sasang constitutional medicine specialist diagnosed the Sasang constitution after analyzing the result of a Two Step Questionnaire for Sasang Constitution Diagnosis (TS-QSCD), the external appearance, temperament and symptoms. The dimensions of TCI and EPQ were compared among the different Sasang constitutions, using an analysis of variance, and correlations between TCI and EPQ were analyzed by a Pearson correlation method. Results : Among the four temperament dimensions of TCI, SY type showed a significantly higher score than the SE type in Novelty Seeking. SE type showed significantly higher score than TE and SY type in Harm Avoidance. SY type showed significantly higher score than SE type in Reward Dependence. TE and SY type showed significantly higher score than SE type in Persistence. There were no significant differences in the character dimensions of Self-directness, Cooperativeness and Self-Transcendence. Among the seven dimensions of EPQ, TE and SY type showed significantly higher score than SE type in Extraversion. SE type showed significantly higher score than SY type in Lie. SY type showed significantly higher score than TE and SE type in Impulsiveness. Conclusions : The results demonstrated that there are some significant differences of personality traits among Sasang constitutions. This could help diagnose and understand each Sasang constitution.

Objectives: The purpose of this study is to evaluate the personality traits and cognitive characteristics of the Sasang constitution by comparing the Eysenck Personality Questionnaire (EPQ), Temperament and Character Inventory (TCI), Continuous Performance Test (CPT) and Stroop Test. Methods: One hundred and six healthy subjects (age 20 to 40) were analyzed; 45 Taeeumin, 30 Soyangin and 31 Soeumin. The Sasang constitution was diagnosed by a sasang constitutional medicine specialist based on the results of a Two Step Questionnaire for Sasang Constitution Diagnosis (TS-QSCD), the external appearance, temperament and symptoms. The results of the EPQ, TCI, CPT and Stroop Test were compared between Sasang constitutions. Results: Among the seven dimensions of EPQ, Taeeumin and Soyangin scored significantly higher than Soeumin in Extraversion. Soyangin scored significantly higher than Soeumin in Impulsiveness. Among the four temperament dimensions of TCI, Taeeumin and Soyangin scored significantly higher than Soeumin in novelty seeking, reward dependence and persistence. Soeumin scored significantly higher than Taeeumin and Soyangin in harm avoidance. Among the three character dimensions of TCI, Soyangin scored significantly higher than Taeeumin in self transcendence. The results for CPT showed no significant differences between sasang constitutions. Taeeumin had a significantly higher color score in the stroop test than Soeumin. Conclusions: The personality tests showed significant differences between Sasang constitutions, but the neuropsychological test did not show any differences. Further studies should be performed to identify neuropsychological differences between Sasang constitutions.

Objectives : This study aims to identify temperament and characteristics of cannabis and methamphetamine abusers for elucidating psycho-biological variables related to certain substance abuse. Methods : A total of 320 patients who registered in the 'Hepatitis C cohorts study of intravenous drug users' between March 2006 and March 2010 participated in this study. Data on demographic variables were obtained and the Temperament and Character Inventory (TCI) and measures for nicotine dependence, alcohol dependence, depression and anxiety were assessed. After comparing TCI between cannabis, methamphetamine, and co-abusers, correlations between TCI and other clinical variables were examined. Results : The methamphetamine abuser group showed significantly higher scores in Novelty Seeking (NS2) and Harm Avoidance (HA3) in temperament than the cannabis abuser and co-abuser groups, whereas the cannabis abuser group had higher scores in purposefulness (SD2), congruent second nature (SD5), and self-directedness (SD) in character than the methamphetamine abuser group. In addition, temperaments and characters correlated with various psychiatric symptoms. Conclusions : We found the differences in temperament and characters among cannabis abusers, methamphetamine abusers. These findings might contribute to further understanding of mechanisms of cannabis and methamphetamine abuse.

Objectives: To compare the biogenetic temperament and character patterns of subjects with narcolepsy and those of healthy control subjects. Methods: Twenty-two subjects with narcolepsy, diagnosed with the International Classification of Sleep Disorder (ICSD) criteria, and 22 healthy control subjects were recruited. The Korean version of the Temperament and Character Inventory was administered to all subjects. Results: Compared to healthy control subjects, subjects with narcolepsy showed significantly higher Novelty-Seeking (ANCOVA, F=5.42, p=0.025), lower Persistence (F=8.41, p=0.006) and lower Self-Directedness scores (F=4.70, p=0.036). Conclusion: Narcoleptic patients have a distinct pattern of biogenetic temperament and character. Our findings suggest that narcoleptic patients are exploratory in response to novelty but give up easily. In addition, our findings show that narcoleptic patients consider themselves ineffective, purposeless, and fragile.

Objectives : The objective of this study is to find out the differences in psychopathology, temperament, and character factors between young adults with and without childhood attention-deficit hyperactivity disorder (ADHD) symptoms. Methods : The subjects consisted of 314 university students (male=72, female=242) in Gongju. They were divided into childhood ADHD group (N=54) and normal group (N=260) to the Wender-Utah Rating Scale. Participants were assessed using Korean Adult ADHD Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, Kimberly Young's Internet Addiction Test, Barratt Impulsiveness Scale, Paranoia Scale, Korean-Schizotypal Ambivalence Scale, Lubben Social Network Scale, and Temperament and Character Inventory-Revised. Descriptive statistics, t-test, chi-square, spearman correlation, and stepwise multiple regression were applied to analyze the data. Results : Participants with childhood ADHD symptoms had high level of adult ADHD symptoms (p<.001), impulsiveness (p=.001), depression (p<.001), anxiety (p<.001), internet addiction (p<.001), paranoia tendency (p<.001) and low level of selfesteem (p<.001) compared to normal group. Self-directedness (p<.001) was lower, Harm avoidance (p=.001) and Self-transcendence (p=.029) were higher in the childhood ADHD group. In correlation and stepwise multiple regression, childhood ADHD symptoms were significantly associated with cooperativeness (r=-0.515 and ${\beta}$=-0.547, p<.001 respectively). Conclusion : This result showed that young adults with childhood ADHD symptoms had various forms of psychopathology and childhood ADHD symptoms were influenced by character such as cooperativeness. Therefore, more thorough evaluation regarding childhood ADHD symptoms is needed.

Objectives : The $2^{nd}$ to $4^{th}$ digit length(2D : 4D) ratio reflects the amount of exposure and sensitivity to the prenatal sex hormone and it is considered to be the most convenient and useful way to understand the influence of sex hormone in the determination of human behavioral traits. This study was carried out to find the correlation between the 2D : 4D ratio and characteristics of temperament and character in Korean university students. We assumed that 2D : 4D ratio would show a strong correlation with temperament which is defined to be an inclination of an automatical emotional response to a stimulus. Methods : Participants were 104 university students who completed 2 self-report measures : Temperament and Character Inventory(TCI), Temperament Test. We examined the 2D : 4D ratio of each subject by measuring the lengths of the $2^{nd}$ and $4^{th}$ fingers using a photocopy measurement. We performed statistical analyses using correlation test and t-test to examine the relationship between 2D : 4D ratio and psychological characteristics. Results : We found out the typical sex difference in 2D : 4D ratio. Women had significantly higher 2D : 4D ratio than men. TCI-Character factor(TCI-C) didn't show any significant correlation with the 2D : 4D ratio. TCI-Tempterament factor(TCI-T) and the item of Temperament Test showed a significant correlation with the 2D : 4D ratio. In correlation analysis of the total group including all women and men, the 2D : 4D ratio showed a significant positive correlation in a subscale(shyness with stranger) of harm avoidance scales in TCI-T. In correlation analysis of women's group, the 2D : 4D ratio showed a significant positive correlation in two subscales( fear of uncertainty) and[shyness to stranger] of harm avoidance scales in TCI-T. In correlation analysis of men's group, the 2D : 4D ratio showed a significant negative correlation with a sanguine temperament item of the Temperament Test. Conclusion : The results suggest that the amount of exposure to sex hormone in the prenatal period seems to have an impact on the determination of temperament and characteristics.

Objectives The purpose of this study was to validate the biopsychological structure of Sasang Personality Questionnaire (SPQ) measuring Yin-Yang temperament with Junior version of Temperament and Character Inventory (JTCI) for temperament and Body Mass Index (BMI) and Pondera Index (PI) for physical constitution in elementary school students. Methods 903 Korean elementary school students (430 boys and 473 girls) completed SPQ, JTCI, and height and weight measures. Then they were analyzed by their genders and age groups. The correlation between SPQ and JTCI subscales were examined. The differences found in the SPQ and JTCI subscales, BMI and PI among high (30%), middle (40%), and low (30%) SPQ groups were investigated by analysis of variance. The profile analysis was also performed to compare JTCI subscale profiles of three SPQ total score groups. Results The SPQ score was significantly (p<0.001), and positively correlated with the JTCI Novelty-Seeking and negatively with the JTCI Harm-Avoidance. The JTCI Novelty-Seeking score of high SPQ group was significantly (p<0.001) higher than that of low SPQ group, and the JTCI Harm-Avoidance score of low SPQ group was significantly higher than that of high SPQ group. The JTCI subscale profiles for three SPQ groups were significantly (p<0.001) different for boys and girls. Significant correlations between BMI and SPQ were not found. PI and BMI of high and low SPQ groups were not significantly different. Conclusions The SPQ was shown to have robust biopsychological structure in elementary school students. It would be useful clinical measures for Sasang typology in pediatric patients.

Objectives : Increasing evidence suggests the presence of neurobiological bases for temperamental characteristics in humans. Brain correlates of harm avoidance(HA) have been most extensively studied using functional and structural brain imaging methods due to its potential link with anxiety and depressive disorders. To date, however, we are not aware of any reports that have examined the potential relationship between HA levels and regional cortical thickness. The aim of the current study is to examine the cortical thickness which is associated with HA temperament in healthy young subjects. Methods : Twenty-eight young, healthy individuals(13 men and 15 women, mean age, $29.4{\pm}6.3$ years) were screened for eligibility and administered the Korean version of the Cloninger's Temperament and Character Inventory and underwent high-resolution structural magnetic resonance imaging scanning. Results : HA was associated with cortical thickness in the right superior frontal cortex and in the left parietal cortex, adjusted for age and sex and corrected for multiple comparisons using the permutation testing method. Conclusion : Individual temperamental differences in HA are associated with structural variations in specific areas of the brain. The fact that these brain regions are involved in top-down modulations of subcortical fear reactions adds functional significance to current findings.

Research on entrepreneurial giftedness is in its initial stage and the importance is increasing these days. The purpose of this article was to provide a standard type of entrepreneurial gifted students by measuring their temperament and character separately. In the year of 2010 to 2011 participants of 'Future Creative Entrepreneur' projects which was governed by Korean Patent Office and Korean Intellectual Property Association participated the present study. They composed of middle and high school students and the total number of them was 246. For all the 7 temperament and character scales; the novelty seeking, the harm avoidance, the reward dependence, the persistence, the self-directedness, cooperativeness, and self-transcendence, scores of the entrepreneurial gifted students were significantly different from the norm group (average students at the same age). In a nut shell, entrepreneurial gifted students were optimistic in their temperament and mature in their character. They also manifested high ability of adjustment and control so they can manage their features of temperament which include all the advantages and weaknesses. The Entrepreneurial gifted students were differentiated from gifted science and math students, academically competent group, and high IQ group. Implications and further research directions were discussed.

Objectives : The purpose of present study is to identify the differences between temperament and character traits among adolescents classified by ego resilience and ego control level. Methods : A Junior Temperament and Character Inventory (TCI) was performed on participants, and a California Child Q-Test (CCQ) was tested for by the parents of the adolescent participants. Results : The result of the factor analysis and discriminant analysis show that the participants are classified into three different groups based on CCQ score and item response patterns. The three groups are named the ego resilience group, the undercontrolled group, and the overcontrolled group. The ego resilience group indicates that they have a high level of interest and curiosity but yet they are not easily tempered. Moreover, they behave proactively with a reasonable level of responsibility in order to improve themselves. In contrast, among the undercontrolled group, it is observed that, although the group shows even higher level of interest, curiosity and honesty, they are careless, more impulsive, and have a lack of delayed gratification and shame. Conclusions : The overcontrolled group shows that they are the most cautious and reflective group among the three but also show emotional instability such as strong criticism and passive-aggressiveness. In this study, implications and limitations are discussed.
