진성남,박두병,김혜련,백형태,Jin, Seong Nam,Park, Doo-Byung,Kim, Hye-Ryun,Baek, Hyung Tae 대한생물정신의학회 2007 생물정신의학 Vol.14 No.3

목 적: 성상세포(astrocyte)에서 생산되어 신경세포의 증식과분화에 관여하는 S100B 단백이 정신분열병의 진행과 증상론과 관련이 있다는 연구가 계속 진행되고 있다. 이에 정신분열병 환자와 정상대조군의 혈청 S100B 농도를 비교하고, 정신분열병 환자의 증상 양상과 S100B 농도와의 연관성을 연구하였다. 방 법: DSM-IV-TR 진단 기준에 따라 정신분열병으로 진단받은 환자 중 정신분열병 최초 발병 환자 혹은 최소 6개월 간 약물 치료를 하지 않은 정신분열병 환자 21명과 정상대조군 27명의 혈청 S100B 농도를 비교하였으며, 정신분열병 환자의 PANSS 전체점수와 양성증상점수, 음성 증상점수 등과 S100B의 혈청농도 간의 상관관계에 대해서 알아보았다. 결 과: 정신분열병 환자에서의 S100B 혈청농도($0.074{\pm}0.039$ ng/ml)와 정상대조군에서의 S100B 혈청 농도($0.072{\pm}0.030$ng/ml)에는 통계적인 차이는 없었다(p=0.925). 또한, 음성증상점수와 S100B 혈청농도(${\rho}$=0.410, p=0.065 ; 표 3)의 상관관계 및 양성증상점수와 S100B 혈청농도 (${\rho}$=-0.390, p=0.080 ; 표 3)의 상관관계는 통계적으로 유의하지 않았다. 결 론: 이번 연구에서 S100B 혈청농도와 정신분열병과의 관련성을 뚜렷하게 발견하기 어려웠다. 이러한 S100B의 역할과 연관성을 확인하기 위해서 연구대상의 확대와 CSF에서의 농도 측정, 장기적 추적 검사, 다른 관련 물질과의 연관성에 대한 추가적인 연구가 필요하다. Objectives:Previous studies have suggested that S100B protein play an important role in the pathogenesis and progress of schizophrenia. In the present study, we evaluate the serum levels of S100B in the patients with schizophrenia, and compare them with those of healthy controls. Method:The serum S100B levels were measured by lectrochemiluminescence immunoassay in 21 schizophrenic patients (8 males, 13 females) and 27 normal controls(11 males, 16 females). The Positive and Negative Syndrome Scale(PANSS) was used to evaluate the symptoms of the patients with schizophrenia, and the correlation between PANSS subscale scores and serum S100B levels was examined. Results:No significant difference was found between the serum S100B levels of the schizophrenic patients($0.074{\pm}0.039$ng/ml) and those of the normal controls($0.072{\pm}0.030$ng/ml)(p=0.925). Correlationships between the high serum S100B level with high negative symptom scores(p=0.065) or with the low positive symptom scores(p=0.080) did not exist. Conclusion:The relation between serum S100B level and schizophrenia was not found in the present study. However, to confirm this result, further studies, such as measurement of S100 protein level in CSF, postmortem study, long-term follow-up study, and studies with other neurotrophic proteins are needed.

원형 탈모증과 안드로겐성 탈모증 여성의 정신적 특성에 관한 연구

박두병,진성남,민경준,노병인,Park, Doo-Byoung,Jin, Seong-Nam,Min, Kyung-Jun,Noh, Byung-In 한국정신신체의학회 2005 정신신체의학 Vol.13 No.1

연구목적 : 장기적인 탈모증의 심리적 영향에 대해 알아보기 위해 탈모증을 겪는 여성 환자에서의 불안, 우울, 감정 표현불능증, 성격 특성에 대해서 알아보았으며, 더불어 유전적 생물학적 원인이 크게 작용하는 안드로겐성 탈모증과 정신적 스트레스의 병인론적 역할에 대한 논란이 있는 원형 탈모증간에 심리적 특성에서 차이가 있는지 알아보았다. 방법: 여성 탈모증 환자를 대상으로 최소 1년 이상 치료를 받고 있는 원형탈모증 환자군(52명)과 안드로겐성 탈모증 환자군(33명), 그리고 정상대조군(54명)에서 다면적 인성검사(MMPI), 벡 우울척도(BDI), 상태불안척도(STAI-S), 특성불안척도(STAI-T), 토론토 감정표현불능증척도(TAS-20K)를 시행하여 각 군간의 차이를 비교 분석하였다. 결과: MMPI 결과는 F척도, Hs척도, D척도, Pd척도, Pa척도, Sc척도, Si척도에서 탈모증 환자군이 정상대조군보다 통계적으로 유의하게 높았고, Hy척도, Pt척도는 안드로겐성 탈모증 환자군에서 가장 높았다. BDI 점수, 상태불안척도, 특성불안척도에서 정상대조군에 비해 원형 탈모증과 안드로겐성 탈모증에서 점수가 높았으며, 특히 BDI 점수에서는 심한 우울증(23점 기준)에 해당하는 경우가 원형 탈모증 환자에서 94.2%(49명), 안드로겐 탈모증 환자의 97.0% (32명)로 나타났다. TAS-20K의 경우 총점에서는 환자군이 정상 대조군에 비해 유의하게 높았으며, Factor 3에서 안드로겐성 탈모증이 타 군에 비해 유의하게 높은 점수를 보였다. 또한 STAI-S 및 STAI-T에서도 환자군이 정상대조군에 비해 유의하게 높은 점수를 보였다. 결론: 여성 만성 탈모증 환자에서 우울감이 두드러지고 불안 수준이 높으며 감정표현불능증의 정도가 더 심한 것으로 나타났다. 특히 이러한 결과는 탈모의 병인론에 관련된 논란에도 불구하고, 두 종류의 탈모증에서 거의 모든 환자가 가지는 우울감에 대해서 적극적인 정신과적 개입이 필요하며, 환자의 성격적 측면과 심리적 대처기 전을 고려해야 함을 의미한다. Objectives : We have studied female patients with either alopecia areata or androgenetic alopecia to evaluate psychological aspects, such as anxiety, depression, alexithymia, and characteristic personalities. In addition, we tried to examine the differences in psychological characteristics between these two types of alopecia, where the alopecia areata has been cotroversial on the role of stress in its etiology and the androgenetic alopecia seems to be more influeced by genetic and biological factors. Methods : All participated patients were females with alopecia for more than 1 you. Among them, 52 were with alopecia areata and 33 were with androgenetic alopecia. They were compared with 54 normal healthy controls by using MMPI, BDI, STAI-S, STAI-T, and TAS-20K. Results The average scores of F, Hs, D, Pd, Pa, Sc, Si in MMPI of alopecia groups were significantly higher than that of normal controls, and the androgenetic alopecia group had highest Hy and Pt scores. The average scores of BDI, STAI-S, and STAI-T in alopecia groups were higher than the normal controls. 94.2% of alopecia areata patients and 97.0% of androgenetic alopecia patients had severe depression, who scored higher than 23 in BDI. In TAS-20K, the average total scores of alopecia groups were higher than the normal control group, and the average Factor 3 score in androgentic alopecia was higher than the other groups. The alopecia groups scored higher than normal control group in STAI-S and STAI-T. Conclusion : Females with chronic alopecia were more depressed, had higher levels of anxiety, and more alexithymic than normal healthy females. In spite of arguments about etiological role of stress to alopecia, psychiatric interventions are needed for depression, and considerations for personality and psychological defense mechanism were needed in both types of alopecia.

In this paper, we have proposed the novel tactile sensor using dielectric elastomer. Our sensor can be considered as a capacitive tactile sensor. A capacitive tactile sensor is based on a capacitor, where the dielectric is made of a compliant material so that the capacitance changes due to the strain exerted on the sensor. In the proposed design, capacitive tactile sensor is implemented using commercially available capacitance to digital converter integrated circuits(CDC), commonly used for example in cell phones. When we touch the sensor surface, the CDC detects the variation of a capacitance and we can know the position of touch through the array of electrodes on the surface. In this paper, we describe the structure of the sensor, material, fabrication process, system configuration and experimental results.

Objective The bulk of recent studies have tested whether video games change the brain in terms of activity and cortical volume. However, such studies are limited by several factors including cross-sectional comparisons, co-morbidity, and short-term follow-up periods. In the present study, we hypothesized that cognitive flexibility and the volume of brain cortex would be correlated with the career length of on-line pro-gamers. Methods High-resolution magnetic resonance scans were acquired in twenty-three pro-gamers recruited from StarCraft pro-game teams. We measured cortical thickness in each individual using FreeSurfer and the cortical thickness was correlated with the career length and the performance of the pro-gamers. Results Career length was positively correlated with cortical thickness in three brain regions: right superior frontal gyrus, right superior parietal gyrus, and right precentral gyrus. Additionally, increased cortical thickness in the prefrontal cortex was correlated with winning rates of the pro-game league. Increased cortical thickness in the prefrontal and parietal cortices was also associated with higher performance of Wisconsin Card Sorting Test. Conclusion Our results suggest that in individuals without pathologic conditions, regular, long-term playing of on-line games is associated with volume changes in the prefrontal and parietal cortices, which are associated with cognitive flexibility.

A event recorder system stores a train speed and the related information for train operation in real time. Using those information, we can analysis the train operation and the reason of train accident. Currently the event recorder only manipulate the data related the train operation mechanically and electrically. In this paper we propose the event recorder to record the voice communication between the manager in the control center and train operator. By recording the voice communication in the high speed train, the correctness of analysis of train accident can be increased. The system architecture of the event recorder with voice recording is studied and interface between other equipment is proposed. And the software architecture of new event recorder is developed. We study the method of converting analog voice signal into digital data and compressing method. Also the architecture of memory to store the compressed voice data and regeneration of original analog voice are studied.
