Objectives: The purpose of this study was to examine the psychological factors of Sasang constitutions which are classified by QSCC II(Questionnaire for Sasang Constitution Classification II) using major personality tests which are based on western psychological theory. Methods: 151 college students completed the MMPI-2, MBTI, NEO-PI-R, TCI-RS, and QSCC II. The data were analyzed by ANOVA and post hoc testing to find which personality scale significantly differentiated each Sasang constitution style. Results: MMPI-2, scale 2(D), 5(Mf), 7(Pt), 0(Si) and introversion scale(INTR) showed significant differences between Soeumin and Soyangin. Also, on the dimension of introversion-extraversion in MBTI, and neuroticism(N) and extraversion(E) in NEO-PI-R, there were differences between Soeumin and the other two constitutions(Soyangin and Taeeumin). Finally, in TCI-RS, there were differences between Soeumin and Soyangin on the scale of novelty seeking(NS) and reward dependence(RD), and with regards to the harm avoidance scale(HA), Soeumin received a higher score than any other constitutions. Conclusions: The analysis demonstrates that the classification of QSCC II is most consistent between Soeumin and Soyangin across 4 major personality tests.

This study found an interesting fact that the nonlinear relationship structure between volatility and trading volume changed before and after the COVID-19 pandemic according to empirical analysis using Bitcoin (BTC) market data that sensitively reflects investors' trading behavior. That is, their relationship appeared positive (+) in a stable market state before COVID-19 pandemic, as in theory based on the information flow paradigm. In a state under severe market stress due to COVID-19 pandemic, however, their dependence structure changed and even negative (-). This can be seen as a consequence of increased market stress caused by COVID-19 pandemics from a behavioral economics perspective, resulting in structural changes in the asset market and a significant impact on the nonlinear dependence of volatility and trading volume (in particular, their dependence at extreme quantiles). Hence, it should be recognized that in addition to information flows, psychological phenomena such as behavioral biases or herd behavior, which are closely related to market stress, can be a key in changing their dependence structure. For empirical analysis, this study performs a test of Ross (2015) for detecting a structural change, and proposes a Copula Regression Quantiles (CRQ) approach that can identify their nonlinear relationship structure and the asymmetric dependence in their distribution tails without the assumption of i.i.d. random variable. In addition, it was confirmed that when the relationship between their extreme values was analyzed by linear models, incorrect results could be derived due to model specification errors.

Nowadays, computer game dependency among adolescents, especially male adolescents, is emerging as a social problem. Therefore, treatment for computer game dependency has become positively necessary. This study aimed at investigating the effects of participation in sociodrama on the students suffering from computer game addiction. For this study, 380 male students in the 8th grade were asked to complete a questionnaire about themselves. After these data had been analyzed using SPSS, eight students were selected as the experimental group. The control group consisted of eight adolescents who were similar to the experimental group in the level of computer game dependency and in the psychological factors such as impulsiveness, depression, and the lack of self-control. The experimental group participated in twelve sociodrama sessions over 11 weeks, whereas the control group did not receive any treatment. The first follow-up test was conducted eleven weeks after the pretest, and the second follow-up test was done nine weeks after the first one. The results indicate that the sociodrama played an important role in alleviating the computer game addiction. At the same time, the participation in sociodrama brought positive changes in the psychological factors of the adolescents.

This study aimed to examine the mediating effects of social withdrawal between adolescents' mobile phone dependence and the sense of community, and to secure the evidence data for adolescents' mobile phone dependence intervention. Among the 7th year data for the 4th grade students in the Korean Children & Youth Panel Survey(KCYPS), 1,979 students were included. The results showed that mobile phone dependence had a significant effect on the decrease in the sense of community and influenced the sense of community through social withdrawal. These results imply that positive intervention to reduce social withdrawal is needed and it can improve the sense of community in youth. Also, when we deal with weakening in the sense of community, we should consider convergent intervention in psychological and social aspects which deal with dependency, social withdrawal, and the sense of community.

The purpose of this study is to analyze the influence of university students' dependence on smart-phone on career attitude maturity and the mediating effect of interpersonal problem in the analysis path. For this purpose, the study implemented a survey on students of universities in Seoul and Gyeonggi-do area and carry out a structural equation for empirical verification with a total of 218 copies. As a result, first, high level of daily life disturbance and virtual world orientation of university students, have a positive effect on interpersonal problems. Second, high level of daily life disturbance and virtual world orientation of university students, have a negative effect on career attitude maturity. Third, interpersonal problems of college students had a negative effect on career attitude maturity, and they were found to be fully mediated in relation to smart-phone dependence and career attitude maturity. Therefore, this study suggests that it can be used as a basic data for the development and application of various programs promoting the career attitude maturity of university students.

Synthetic cannabinoids (CBs) such as the JWH series have caused social problems concerning their abuse liability. Because the JWH series produces euphoric and hallucinogenic effects, they have been distributed illegally under street names such as "Spice" and "Smoke". Many countries including Korea have started to schedule some of the JWH series compounds as controlled substances, but there are a number of JWH series chemicals that remain uncontrolled by law. In this study, three synthetic CBs with different binding affinities to the $CB_1$ receptor (JWH-073, 081, and 210) and ${\Delta}^9$-tetrahydrocannabinol (${\Delta}^9$-THC) were evaluated for their potential for psychological dependence. The conditioned place preference test (unbiased method) and self-administration test (fixed ratio of 1) using rodents were conducted. $K_i$ values of the three synthetic cannabinoids were calculated as supplementary data using a receptor binding assay and overexpressed $CB_1$ protein membranes to compare dependence potential with $CB_1$ receptor binding affinity. All mice administered JWH-073, 081, or 210 showed significantly increased time spent at unpreferred space in a dose-dependence manner in the conditioned place preference test. In contrast, all tested substances except ${\Delta}^9$-THC showed aversion phenomenon at high doses in the conditioned place preference test. The order of affinity to the $CB_1$ receptor in the receptor binding assay was JWH-210 > JWH-081 >> JWH-073, which was in agreement with the results from the conditioned place preference test. However, no change in self-administration was observed. These findings suggest the possibility to predict dependence potential of synthetic CBs through a receptor binding assay at the screening level.

This is a pilot study on rural women's psychological trap to define some obstacles to self directed learning. During few decades, according to major crop of each farm household has shifted from rice to other crops like as vegetables, fruits, horticultures, livestock, etc., women's role or labor sharing of women in farming has been also increased. Although women are important human resources, till now, there is no a research or an approach to rural woman on the view of individual human being. Therefore this study will contribute to understand woman's behavior or attitudes based on psychological description at each person's experiences. For this study, the data was collected from 23 women leaders who participated in a training course in 2005, through the scale of Jeffrey E. Young & Janet S. Klosko which was developed to improvement of one's repetitious behavior based on cognitive psychological care. It was categorized into 11types of psychological trap of one person, named as follows; (1) trap of being deserted by someone (2) trap of disbelief and being ill-treated (3) trap of weakness (4) trap of dependence (5) trap of emotional deprivation (6) trap of feelings of alienation among society (7) trap of deficiency (8) trap of anxiety to failure (9) trap of subordination (10) trap of the merciless standard by self-estimation (11) trap of the sense of privilege. From the data, the average age of subjects was 52.8years old, and the educational back of subjects was higher than general rural women. In both of the trap of weakness and the trap of the merciless standard by self-estimation, the ratio of over and 4 point score of 6 points was 71.4% and 76.2%. It means most of subjects have experienced fear of unexpected calamity(trap of weakness), and mental press hard for efforts to meet one's ideal standard(trap of the merciless standard by self-estimation). Especially the trap of the merciless standard by self-estimation may have relation with rural women's over burden from farming and local society activities.

The purpose of this study is to evaluate the effects of the acceptance commitment therapy program (ACT) on the psychological flexibility, self-compassion, recovery in alcohol dependents. The ACT program contains skills that establish acceptance and willingness, defusion, self-as-context, contact with the present moment, clarifying values, and committed action. This study was intended to enhance the effects on the psychological flexibility, self-compassion, recovery in alcohol dependents with ACT program. Fifteen inpatients with alcohol dependence were participated in the ACT group and the same number of participants were in the both CBT control group and TAU control group. The ACT program was held once a week, eight times, and each session was 90-minute long. Repeated measure of MANOVA and post-hoc were used to compare pre-test mean with post-test and with follow-up test mean. As a result of ACT program, positive changes were assured in the psychological flexibility including acceptance, cognitive defusion, being present, committed action and the increase of self-compassion and of recovery in alcoholics.

In the experiment carried out on 20 college students, recorded were frontal, temporal and occipital EEG, skin conductance response, skin conductance level, heart rate and respiration rate during listening to two music fragments with different affective valences and white noise administered immediately after negative visual stimulation. Analysis of physiological patterns observed during the experiment suggests that affective auditory stimulation with music is able to selectively modulate autonomic and cortical activity evoked by preceding aversive visual stimulation and to restore initial baseline levels. On other hand, physiological responses to white noise, which does not possess emotion-eliciting capabilities, evokes response typical for orienting reaction after the onset of a stimulus and is rapidly followed by habituation. Observed responses to white noise were similar to those specific to attention only and had no evidence for any emotion-related processes. Interpretation of the obtained data is considered in terms of the role of emotional and orienting significance of stimuli, dependence of effects on the background physiological activation level and time courses of attention and emotion processes. Physiological parameters are summarized with regard to their potential utility in differentiation of psychological processes induced by auditory stimuli.

A growing number of people are concerned about their sleep. There are many people with chronic sleep disorders. As there are various causes in a disease, proper treatment according to each cause is necessary for a more effective treatment. In general, insomnia is classified into five categories of physical, physiological, psychological, psychiatric and pharmacological aspects. Sedative-hypnotics including benzodiazepine and non-benzodiazepine have widely been used in chronic insomniacs. However, most hypnotics including non-benzodiazepine cause some of dependence, tolerance, impaired daytime function and rebound insomnia. Therefore, we are looking forward to proposing an effective oriental treatment for insomnia. A 71-year-old male who had suffered from cerebral infarction was admitted to our department for oriental treatment of stroke and insomnia. Initial treatment modalities with administration of paroxetine were not effective. However administration of oriental medicine' Gochimmuwoo-san(Gaozhenwuyou-san)' achieved a desirable effect.
