The purpose of this study is to examine the emergence and development of green parties around the world to identify general conditions for their growth and to see if the findings can be applied to the Korean Green Party. In doing so, it explores the requirements of a political party based on the experience of the Korean Green Party. The empirical analysis shows that in terms of political opportunity structure, green parties around the world grow into parties that influence the political system when elections are highly proportional and the proportional representation rate is above 40%. However, in the case of the Korean Green Party, the limitations of the quasi-connected proportional representation system with a ‘cap’ clause and the emergence of satellite parties in the 2020 general election resulted in lower electoral proportionality than before, and the proportional representation rate was only 15.67%, which did not have favorable conditions for growth. Next, in terms of party leadership, global green parties have observed that green parties grow when they maintain intra-party unity and pursue coalition politics in elections. However, the Korean Green Party failed to create a growth engine during the 2020 general election, as it failed to maintain intra-party unity and pursue coalition politics. Based on this analysis, in order for the Korean Green Party to grow in the future, the party leadership should focus its efforts on introducing a more proportional electoral system and expanding the number of seats for proportional representation, while maintaining intra-party unity and pursuing coalition politics.

Objectives:This study was aimed to investigate whether 1) sexual dimorphism in subcortical gray matter volumes (GMV) and the length ratio between the second and fourth digits (2D:4D) would be found and 2) 2D:4D would have associated with subcortical GMV in healthy elderly people. Methods:Sixty-two females aged 70.3±6.3 (mean±SD) years and 23 males aged 70.4±4.9 years were recruit ed from the Dementia Clinic in the Pusan National University Hospital. The subjects with the clinical dementia rating scale-sum of boxes (CDR-SB) total score greater than 2.0, any psychiatric or neurological disease, or any pathologic lesion on brain MRI other than micro-angiopathy were excluded. The 2D:4D of the left and right hands were measured 3 times each. Volumetric segmentation of T1-weighted MRI scans was done by Freesurfer software (v7.1.1.1). Results:2D:4Ds of males were smaller than those of females significantly on repeated measures ANOVA. The males’ thalamus, putamen, hippocampus in both hemispheres and the right amygdala were larger than females’. These differences were not significant after controlling for age, education and total intracranial volume (ICV). In the females, the left 2D:4D was negatively correlated with the left hippocampal volume. In the males, 2D:4D was positively correlated with the volumes of ipsilateral or contralateral thalamus, hippocampus, amygdala and accumbens. These correlations were not significant after Bonferroni’s correction, except for the right accumbens. Conclusions:Sexual dimorphism of 2D:4D is preserved in healthy elderly people. There is a significant correlation between the right 2D:4D and GMV of the accumbens in males

강박장애의 인지행동치료

박제민 대한생물치료정신의학회 2001 생물치료정신의학 Vol.7 No.1

Theoretical backgrounds , therapeutic efficacy, and practical procedures were reviewed to compare behaviour therapy with cognitive therapy for obsessive compulsive disorder, Exposure and response prevention showed superior therapeutic effect in terms of both acute symptom reduction and long-term outcomes. Though cognitive therapy needs more empirical data, it has some benefits for the patients to whom ERP is not applicable or less effective, such as the patients with pure obsessions , aggressive urges, or mental rituals. According wish recent development in neuropsychology and functional neuroimaging techniques, cognitive process model is one of most promising areas expected to solve OCD puzzles. Future studies should be directed to answer the question , "To whom what therapy?".

강박장애의 행동치료 : 노출과 반응차단 Exposure and Response Prevention

박제민 釜山大學校 醫科大學 精神科學敎室 1997 釜山精神醫學 Vol.6 No.-

This paper is written to remind the Korean psychiatric society of behaviour therapy(BT), mainly exposure and response prevention(ERP), as one of the therapeutic options with better longterm prognosis for obsessive-compulsive disorder (OCD). Initial and regular assessments do critical role in BT. During 2 or 3 initial assessment sessions, the-rapist evaluates symptom areas and severity, suitability for BT, and other factors influencing therapeutic out-come, such as presence of co-morbid psychiatric disorders and personality traits. Therapeutic goals and target symptoms should be specific, measurable and reasonable. The patient(and co-therapist) should be informed about how ERPworks, what they are expected to do during treatment, how they estimate their symptoms and keep diary. Basic principles and types of ERP is reviewed with emphasis on the importance of self-exposure, mental ritual prevention, and generalization. Issues regarding management of pure obsessions and co-morbid mental disorders and discussed briefly.

한국어판 PADUA 강박척도 : 신뢰도와 타당도 Reliability and Validity

This study reports the psychometric peroperties and factorial structure of a Korean version of the Padua Inventory (PI) in clinical (35 patients withobsessive-compulsive disorder and 66 with other psychiatric disorders) and non-clinical (458 including 120 undergraduate medical students) samples. The PI total and subscales showed good internal consistency, convergent and known-group validity. Test-retest reliability with interval of one year was superior to that of obsessive-compulsive subscale of SCL-90R. PI scores of non-clinical sample were lower than those reported in western countries, apart from Dutch sample. Principal component analysis on data from whole sample suggested four-factor solutions, which was comparable to that found in other versions of the PI developed in the western cultures. Items asking urges or worries of breaking or stealing things were separated from the factor 'urges and worries of losing control over motor behavior'. Factor analysis on data from non-clinical sample revealed five-factor solution: being contaminated, checking behaviors, doubting, worries of disasters, and ruminations. The first two factors were very same as the western reports, the other three were comparable to 'impaired control over mental activities', but 'urges and worries of losing control over motor behavior' was not extracted as a separate factor in this study. Needs for cross-cultural study including other Asian countries arise to confirm lower PI scores and different factor structures in this sample reflects Korean-specific or Asian-specific culture.

장기적 트립토판 결여식이 생쥐의 강제수영 중 부동자세시간에 미치는 영향

박제민,김명정,양구범,전명호,서영대,김성곤 釜山大學校 醫科大學 精神科學敎室 1998 釜山精神醫學 Vol.7 No.-

To investigate possible relationship between depression and chronic decrease of serotonin, immobility time during forced swimming test(IT) and motor activity(ACT) in open field test weremeasured in mice raised with 4 weeks of tryptophan-free or control diet. The results were 1) IT was not affected by tryptophan depletion neither gender, 2) forced swim-induced behavioral inhibition was not observed in tryptophan depleted male mice, 3) muricidal behavior was increased in tryptophan depleted male mice. It was suggested that chronic decrease in serotonin level affected stress-related animal behavior gender dependently, and it might be related with a certain type of depression, agitated depression in males, for an example.

To test the hypothesis that the difference in pain threshold is one of biological mediators involved in repetitive self-injurious behavior(SIB), the author evaluated the frequency and number of SIB, measured pain threshold with a pressure algometer, and scored emotional status with Zung`s self-rating depression scale(SDS) and Irritability Depression Anxiety scale(IDA). The subjects were male adolescents with repetitive SIB(N=37), Single SIB(39), and without SIB(45). The subjects who did SIB within 3 months or who had present or past history of major physical illness or psychotic episode were excluded. The results were as follows; 1) Repetitive SIB group was significantly insensitive to painful stimuli than One or No SIB group. 2) There was no significant difference in depressive or anxiety symptoms between Repetitive SIB and One SIB group. 3) In SIB group, pain threshold was positively correlated with average number of self-injurious wounds per one self-injurious behavior significantly. From these results, the author suggests that lower sensitivity to painful stimuli in basal state may be one of biological mediators involved in repetitive SIB.

생쥐의 강제수영으로 인한 통각둔화 현상에 미치는 P-Chlorphenylalanine과 Naloxone의 효과

정환증,김명정,박제민 大韓神經精神醫學會 1992 신경정신의학 Vol.31 No.5

In order to test a hypothesis that the hypoalgesia induced by forced swimming in mice is mediated by central opioid neurons and serotonergic neurons, pain sensitivity was measured by means of tail flick test before and after forced swimming and the effect of naloxone, pchlorophenylalanine(PCTA) and 5-hydroxytryptophan(5HTP) on the change of pain sensitivity was observed to obtain the following results. 1) Pain sensitivity was significantly reduced by forced swimming. 2) Hypoalgesia induced by forced swimming was blocked by naloxone pre treatment(2mg/kg). 3) Naloxone pretreatment did not change the pain sensitivity before forced swimming. 4) PCPA pretreatment(300mg/kg once daily for 3days) blocked the hypoalgesic effect induced by forced swimming. 5) PCPA pretreatment did not change the pain sensitivity before forced swimming. 6) 5HTP reversed the effect of PCPA. 7)Large dose(100-200(mg/kg) of 5HTP not only reversed the effect of PCPA, but also reinforced hypoalgesic effect induced by forced swimming. 8) 5HTP pretreatment did not alter the pain sensitivity before forced swimming in PCPA pretreated and control group. From these results it is suggested that the hypoalgesia induced by forced swimming in mice is mediated by activation of endogenous opioid system that requires coaction of 5HT system.
