This study examined the differences in facial emotion processing related to psychopathic traits. On the basis of the Psychopathic Personality Inventory-Revised (Lee & Park, 2008), students were divided into psychopathic trait (n=15) and control (n=15) groups. Participants performed two tasks consisted of negative(angry, fear, sad) and neutral faces. Event-related potentials(EPRs) were recorded when participants categorized gender in the implicit task and emotion in the explicit task. We analyzed the late positive potentials(LPP) amplitude to investigate differences in emotion processing between psychopathic trait group and control group. In the implicit task, there was no significant difference in both groups. However, there was a significant interaction between emotion and group at the frontocentral region in the explicit task. The psychopathic trait group showed greater LPP amplitudes for the neutral faces than for the negative faces, whereas the control group showed similar LPP amplitudes for the neutral and negative faces at the frontocentral site. These results might reflect the abnormalities in emotional processing in individuals with psychopathic traits.

This study investigated gender differences in contribution of antisocial personality and affective empathy to psychopathy. Two hundred fifteen college students (male, 118; female,97) completed three measures including the PPI-R(Psychopathic Personality Inventory-Revised), the PAI-ANT(Personality Assessment Inventory-Antisocial Features), and the EETS (Emotional Empathy Tendency Scale). According to the results, the mean scores of PPI-R and EETS in male group were higher than in female group. Antisocial features were positively associated with psychopathy in both male and female groups and negatively with affective empathy. Males showed that the scores of affective empathy were negatively associated with those of antisocial features and psychopath. Females showed that the scores of affective empathy were negatively associated with those of antisocial personality and psychopathy but the correlation was significant only with the scores of antisocial behavior (ANT-A). To scrutinize the differences between male and female groups, the scores on the PAI and EETS were compared between 30% upper and 30% lower groups based on the scores of the PPI-R. According to the results, the upper group of the scores on the PPI had higher scores on the PAI and lower scores on the EETS. The differences of the scores on the EETS between high-psychopathy and low-Psychopathy groups were bigger in male group than in female group. Explanations and implications of the results were discussed and the directions of the future studies were suggested.

This literature review introduced the concept of psychopathy which has never been defined academically in Korea. Also it is reviewed how this concept could be applied as latent factor of criminal behavior in the forensic settings. For this purpose, first of all, the periodical change of psychopathy definition was explored. Then it was investigated which determinants might develop psychopathy and what would be the behavioral characteristics of psychopaths. Finally, risk assessment tools measuring psychopathy were introduced and their predictive efficacy and applicability in Korean criminal justice system was discussed.

Objectives : The risk of weight gain is high when using antipsychotic drugs, and the prevalence of obesity in people with mental illness is high. Obesity management in psychiatric patients is important because obesity causes various complications and lowers treatment adherence and quality of life. Methods : In this review, we summarized the management strategies for obesity that can occur when using antipsychotic drugs through a web search. Results : Evaluate obesity-related risk factors and related indicators from the beginning of treatment, and conduct regular monitoring. If an antipsychotic drug is used and obesity is induced, a change to a drug with a low metabolic risk may be attempted. Sufficient interventions are also needed on the need to manage obesity, a healthy diet, and exercises in patients and their families. If weight loss is not achieved and obesity-related complications are associated, the use of anti-obesity drugs may be considered. Pharmacological treatment approaches should be carefully considered. Conclusions : Non-pharmacological and pharmacological therapies can be applied to manage weight gain and obesity caused by the use of antipsychotic drugs. When using anti-obesity drugs, the characteristics of mental disorders, drug safety, and drug interactions should be considered.

This paper is a preliminary literature review to give lights on the importance of academic research on sex offences. First, definition and etiological factors of sex offences were introduced and then it was attempted to classify offensive behaviors. Furthermore, it was explored on which aspects of our criminal justice system the research results in the Western societies could be applied. Related to recidivism research, risk factors were explored again and intervention strategies were investigated to reduce the future risk of sex offenders. Finally, these findings were evaluated for the applicability to Korean criminal justice system.

Objectives : Antipsychotic-induced hyperprolactinemia causes physical symptoms, such as amenorrhea, galactorrhea, gynecomastia, sexual dysfunction, and bone density loss, as well as psychiatric symptoms, such as depression and cognitive impairments. This study aimed to clarify the associations among hyperprolactinemia caused by antipsychotics in patients with schizophrenia, psychiatric pathology, and psychosocial factors. Methods : Ninety-nine patients with schizophrenia in the psychiatry department of a university hospital were registered between 2015 and 2017. All participants were assessed using structured questionnaires to elucidate psychopathology, social function, quality of life, and hyperprolactinemia-related side effects. The standard levels for hyperprolactinemia were 24ng/mL for women and 20ng/mL for men. Results : The average prolactin levels were $73.45{\pm}49.37ng/mL$ in patients with hyperprolactinemia and $9.16{\pm}6.42ng/mL$ in those without hyperprolactinemia. The average prolactin level in women was significantly higher than that in men(p=0.04). Risperidone was most commonly administered in patients with hyperprolactinemia(58.1%, p<0.01), while aripiprazole was most commonly administered in those without hyperprolactinemia(44.7%, p<0.01). Patients with hyperprolactinemia had significantly higher Positive and Negative Syndrome Scale(p=0.03) and Patient Health Questionnaire-9(p=0.05) scores and had significantly lower Social and Occupational Functioning Assessment Scale(p=0.04) and Strauss-Carpenter Levels of Functioning Scale(p=0.03) scores than patients without hyperprolactinemia. There were no significant differences in side effects or quality of life between the two groups. Conclusion : These findings demonstrate that hyperprolactinemia confers negative effects on depression and social function, but does not directly affect the quality of life. These results suggest that patients with schizophrenia who take antipsychotics that increase prolactin or cause side effects of hyperprolactinemia need to be assessed and receive interventions for depression.

Objectives : This study was to assess the prevalence and its correlates of restless legs syndrome(RLS) in outpatients with bipolar disorder. Methods : A total of 100 clinical stabilized bipolar outpatients were examined. The presence of RLS and its severity were assessed using the International Restless Legs Sydrome Study Group(IRLSSG) diagnostic criteria. Beck's Depression Inventory(BDI), Spielberg's State Anxiety Inventory(STAI-X-1), Pittsburgh Sleep Quality Index(PSQI), Korean version Drug Attitude Inventory(KDAI-10), Subjective Well-Beings under Neuroleptic Treatment Scale-Short Form(SWN-K) and Barnes Akathisia Rating Scale(BARS) were used to evaluate the depressive symptomatology, level of anxiety, subjective quality of sleep, subjective feeling of well-being, drug attitude, presence of akathisia, respectively. Results : Of the 100 bipolar outpatients, 7(7%) were met to full criteria of IRLSSG and 36(36%) have at least one of the 4 IRLSSG criterion. Because of relatively small sample size, non-parametric analysis were done to compare the characteristics among 3 groups(full-RLS, 1 ${\geq}$positive RLS-symptom and Non-RLS). There were no significant differences in sex, age, and other sociodemographic and clinical data among 3 groups. BDI, STAI-X-1 and PSQI are tended to be impaired in RLS and 1 ${\geq}$positive RLS-symptom groups. Conclusions : This is the first preliminary study for studying the prevalence and its correlates of RLS in bipolar disorder. The results shows that relatively small proportion of RLS was present in bipolar disorder patients when compared to patients with schizophrenia. Same tendencies shown in schizophrenic patients were found that bipolar patients with RLS had more depressive symptoms, state anxiety and poor subjective sleep quality. Further systematic studies may be needed to find the characteristics of RLS in bipolar patients.
