Purpose: The purpose of this study was to analyze the smoking behaviors and to identify the impact of depression, temperament, and characteristics of smoking experience on rural adolescents. Method: A survey using a self-administered questionnaire was done of 310 rural high school students. Using SPSS 12.0, Pearson correlation coefficients and multiple regression were used to analyze the data. Results: The smoking rate of rural high school students was higher than that of the national rate for this age group. Serious depression was observed in the rural high school students. There was a positive correlation among smoking experience, school records, novelty seeking and a negative correlation between smoking and cooperativeness. The significant predictors of smoking experience were type of school, satisfaction with school, school records, novelty seeking, reward dependence and cooperativeness. These factors accounted for 38.9% of variances in the smoking experience of rural adolescents. Conclusion: These results suggest that adolescents who exhibit factors identified in this study are regarded as having the potential to smoke, and this result proposes the basis for program development for the prevention of smoking and smoking cessation.

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.

Nowadays, recommender systems suggest lists of items to users considering not only accuracy but also diversity and novelty. However, suggesting the most diverse list of items to all users is not always acceptable, since different users prefer and/or tolerate different degree of diversity. Hence suggesting a personalized list with a diversity degree considering each user preference would improve the efficiency of recommender systems. The main contribution and novelty of this study is to tune the diversity degree of the recommendation list based on the users' variety-seeking feature, which ultimately leads to users' satisfaction. The proposed approach considers the similarity of users' desire diversity as a new parameter in addition to the usual similarity of users in the state-of-the-art collaborative filtering algorithm. Experimental results show that the proposed approach improves the personal diversity criterion comparing to the closest method in the literature, without decreasing accuracy.

Objectives : Novelty seeking (NS) represents a dopaminergically modulated tendency toward frequent exploratory activity. Considering the reports showing the relationship between exploratory activity and amygdalar function and structure, and the fact that amygdala is one of the key structures that constitute the dopaminergic pathway in the brain, amygdala might be closely related to NS tendencies. Amygdalar subregional analysis method, which has the enhanced sensitivity compared to the volumteric approach would be appropriate in investigating the subtle differences of amygdalar structures among healthy individuals. The aim of the current study was to examine whether amygdalar subregional morphometric characteristics are associated with the NS tendencies in healthy adults using the amygdalar subregional analysis method. Methods : Twenty-six healthy adults (12 males, 14 females ; mean age $29.8{\pm}6.2$ years) were screened for eligibility. All subjects completed the Korean version of the Temperament and Character Inventory (TCI) and underwent high-resolution brain magnetic resonance imaging. Individuals were divided into 2 groups according to NS scores of the TCI. Results : Individuals of the high NS group had significantly larger laterobasal subregions in right amygdala, after adjustment with the brain parenchymal volumes. Sensitivity analyses for each potential confounding factor such as age, education years and Hamilton Depression Rating Scale (HDRS) scores demonstrated consistent results. Conclusions : This study suggests that NS differences are associated with the laterobasal subregion of the amygdala.

Objectives The Eum-Yang (Yin-Yang in English) temperament was shown to have clinical and structural validity with Sasang Personality Questionnaire (SPQ), however the studies of the association with behavior problems and personality structure in adolescents were not satisfactory. The purpose of this study was to examine the relationships between Eum-Yang temperament and behavior problems in Korean middle school students. Methods 122 first grader of middle school students (68 boys and 54 girls) completed SPQ, Junior version of Temperament and Character Inventory (JTCI), and Youth Self Report (YSR). The correlations between SPQ, JTCI, and YSR subscales were investigated. And, also the differences between SPQ, JTCI, and YSR subscales among Yang (high 30% of SPQ total score) and Eum (low 30% of SPQ total score) temperament groups classified with SPQ total score were examined. Results The SPQ total score were correlated with Novelty-Seeking (r=.321) and Reward-Dependence (r=.392) in boys, and with Novelty-Seeking (r=.427) and Harm-Avoidance (r=-.444) in girls. The SPQ total score were not significantly correlated with Body Mass Index, Ponderal Index and YSR total, however significantly correlated with YSR Internalizing problems and Withdrawal/depressed subscale (r=-.242 and r=-.419) in boys and Withdrawal/depressed subscale (r=-.449) in girls. There were significant differences between Eum and Yang groups in Novelty-Seeking, Harm-Avoidance and Withdrawal/depressed as for boys and girls. Conclusions The biopsychological structure of SPQ was confirmed with middle school students. The behavioral (SPQ-B) and emotional (SPQ-E) perspectives of Eum-Yang were found to be protective and risk factors, and also correlated with Externalizing and Internalizing behavior problems, respectively. The biopsychological characteristics of Eum-Yang temperament and its relation with psychopathological symptoms in late-childhood should be carefully analyzed.

Objectives : The purpose of this study was to investigate the relationships between mother's and child's temper and parenting stress. Methods : One hundred twenty healthy mothers (above 20 yrs old) who has a school-aged child (7-11 yrs old) participated after informed consent. The temperament of the children was analyzed by the Junior Temperament and Character Inventory 7-11 (JTCI 7-11) by their mothers. The temperament of the mothers was analyzed by the Temperament and Character Inventory-Revised Short (TCI-RS) and the mother's parenting stress was analyzed by the Korean Parenting Stress Index (K-PSI). The relationships between mothers' and child's temperament and parenting stress were assessed using the Pearson correlation coefficient and multiple regression test. Results : There were significant correlations between maternal temperaments and child's temperaments and maternal parenting stress. There was a positive correlation between mother's harm avoidance characteristic, child's novelty seeking degree and parenting stress. On the other hand, there was a negative correlation between child's persistence and parenting stress. In addition, interactions between child and mother temperament dimensions predicted higher levels of parenting stress. Parenting stress was higher in the group of high mother's harm avoidance with child's high novelty seeking and high mother's harm avoidance with low child's persistence. Conclusions : These results are showing that there are significant relationships between mother and child temperament and parenting stress in mothers with school-aged children.

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.

Behavioral analysis in mice provided important contributions in helping understand and treat numerous neurobehavioral and neuropsychiatric disorders. The behavioral performance of animals and humans is widely different among individuals but the neurobehavioral mechanism of the innate difference is seldom investigated. Many neurologic conditions share comorbid symptoms that may have common pathophysiology and therapeutic strategy. The forced swim test (FST) has been commonly used to evaluate the "antidepressant" properties of drugs yet the individual difference analysis of this test was left scantly investigated along with the possible connection among other behavioral domains. This study conducted an FST-screening in outbred CD-1 male mice and segregated them into three groups: high performers (HP) or the active swimmers, middle performers (MP), and low performers (LP) or floaters. After which, a series of behavioral experiments were performed to measure their behavioral responses in the open field, elevated plus maze, Y maze, three-chamber social assay, novel object recognition, delay discounting task, and cliff avoidance reaction. The behavioral tests battery revealed that the three groups displayed seemingly correlated differences in locomotor activity and novel object recognition but not in other behaviors. This study suggests that the HP group in FST has higher locomotor activity and novelty-seeking tendencies compared to the other groups. These results may have important implications in creating behavior database in animal models that could be used for predicting interconnections of various behavioral domains, which eventually helps to understand the neurobiological mechanism controlling the behaviors in individual subjects.

As interest in the environment increases, consumers increasingly choose to buy products with eco-friendly production processes. The purpose of this study was to determine the effect of consumption values and materialism/voluntary simplicity on the attitudes and purchase intentions toward eco-friendly fashion products. A survey of university students in Seoul was conducted and 203 questionnaires were analyzed using SPSS 23.0. The consumption values consisted of six factors: subjective value, novelty value, social value, brand value, practical value, and health/safety value. Materialism/voluntary simplicity was grouped into two factors of materialism pursuit and voluntary simplicity pursuit. Brand values were found to negatively affect attitudes toward eco-friendly fashion products. The more one pursued brand names, the more negative was one's attitude toward eco-friendly fashion products. Health/safety values had a positive effect on purchase intentions for eco-friendly fashion products and voluntary simplicity pursuit had a positive effect on both attitudes and purchase intentions. The materialist group had high subjective value, novelty value, social value, and brand value among the consumption values, and the voluntary simplicity-seeking group tended to pursue the value of health and safety. This study was meaningful in that it identified the characteristics of consumers showing favorable attitudes toward eco-friendly fashion products.
