주정중독환자의 혈소판막과 $^{125}I-LSD$ 결합에 관한 연구

정영철,은홍배,Chung, Young Chul,Eun, Hong Bai 대한생물정신의학회 1996 생물정신의학 Vol.3 No.2

본 연구는 알코올사용장애 환자의 혈소판막에 있는 serotonin수용체가 대조군과 비교했을 때 어떤 차이가 있는지 알아보기 위해 시행되었다. $_{125}I-LSD$를 radioligand로 사용하여 포화반응을 해 봄으로서 다음의 결과를 얻었다. 1) 환자군과 대조군간은 $B_{max}$에 있어서만 유의한 차이를 보였다(P<0.0017). 2) Type 1군과 type 2군 사이 역시 $B_{max}$에 있어서만 유의한 차이를 보였다(P<0.0396). 3) 알코올남용군과 알코올의존군 사이의 $B_{max}$와 $K_d$는 모두 유의한 차이가 없었다. 위 결과들은 알코올사용장애의 serotonin 결핍가설을 지지해주며 혈소판의 serotonin 수용체 수의 증가가 알코올사용장애의 trait marker가 될 수 있음을 시사해 준다. This research was performed to find out the changes of serotonin receptors in the platelet of alcoholics. Using $_{125}I-LSD$ as a radioligand. We obtained the following results. 1) In the comparison of patients vs controls, $B_{max}$ of the former was significantly higher than that of the latter(P=0.0017). But there was no significant difference in the Kd between the two groups. 2) In the comparison of type 1 vs type 2, alcoholics by cloninger's classification $B_{max}$ of the latter was significantly higher than that of the farmer(P=0.0396). But there was no significant difference in the Kd between the two groups. 3) In the comparison of alcohol abuse vs alcohol dependence, there were no significant differences in the value of $B_{max}$ and Kd between the two groups. These results support the hypothesis of serotonin-deficit in alcoholism. Furthermore, it can be inferred that the increase of platelet serotonin receptors in alcoholics might be used as a trait marker.

정영철,임수덕,윤재일,허충림,한을남 대한피부과학회 1982 大韓皮膚科學會誌 Vol.20 No.6

We observed three patients who showed widespread macular ashy-colored eruptions. They fit clinically and histopathologically with the typical erythema dyschromicum perstans (ashy dermatosis). Erythoma dyschromicum perstans is a peculiar pigmented condition of unknown etiology characterized by persistent ashy-gray colored macule, refractory to any modality. All of them have similar skin lesions which are multiple, variable sized oval-shaped, ash-colored macular eruption on the trunk and extremities. Histologic findings of 2 patients reveal the characteristic feature of focal hydropic degeneration of the basal cell layer of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium, however, merely pigmentary incontinence into the corium in 1 patient. Literatures are briefly reviewed.

The attitude of the Korean for dwelling house and the viewpoints about nature are described in 'Shijo(a kind of short lyric poem)'. The purpose of this study is to find out the concepts of Korean traditional dwelling house through the 'Shijo'. The results of study are as follows. The concept of the traditional house is that the houses are regarded as a place of ideal seclusion, a part of nature, a resting place, a place of social life. The garden was composed of the natural and artificial element on principle of naturalness and introduction of the natural landscape, and the composition elements of the garden had the symbolic meanings.

입수 충격 수중 순간 소음에 대한 실험적 연구

정영철,성우제,이근화,김형록,Jung, Youngcheol,Seong, Woojae,Lee, Keunhwa,Kim, Hyoungrok 한국음향학회 2014 韓國音響學會誌 Vol.33 No.1

본 연구에서는 입수 충격에 의한 수중 순간 소음을 연구하기 위해, 황해에서 발사대를 이용하여 해상 실험을 진행하였다. 해상시험선인 청해호 우현상에서 발사대를 이용하여 실린더 몸체를 수직으로 발사하였으며, 이때 발생하는 소음을 하이드로폰으로 측정하였다. 실험에서는 원통형, 원뿔형, 반구형 두부 형상을 가진 3가지 종류의 실린더 몸체가 사용되었다. 측정된 신호는 시간적으로 확연하게 구분되어 3단계로 전시되었다 : (1) 초기 충돌 및 물체 진동단계, (2) 개방 공동 유동 단계, (3) 공동 붕괴 및 거품 진동 단계. 대부분의 경우, 거품 진동 단계의 파형이 초기 충돌 및 물체 진동 단계에 비해 우세하게 나타났다. 공동이 붕괴되기 시작하는 핀치 오프 시간은 0.18 ~ 0.2 s에 발생하였으며, 평균 거품 지속 시간은 0.9 ~ 1.3 s로 지속되었다. 입수 충격 소음은 100 Hz 이하의 대역에서 에너지가 집중되어 있었으며, 생성되는 소음은 두부 형상, 물체 질량, 발사 속도에 의해 영향을 받았다. 결과적으로, 거품 주파수에서 에너지 스펙트럼 밀도의 크기는 원통형, 원뿔형, 반구형 순으로 나타났으며, 동일 입수체에 대해서는 초기 에너지가 클수록 거품 주파수에서 에너지 스펙트럼 밀도가 크게 나타났다. 최종적으로, 버블이 폭발하는 물리적 현상을 기반으로 모의된 신호와 계측 값간 비교 결과 만족스러운 결론을 얻을 수 있었다. To study the water-entry impact noise, on-board experiment using a small launcher firing various objects was performed in the Yellow Sea. As the launcher fires a cylindrical object from the ship vertically, generated noise is measured with a hydrophone on the starboard of Chung-hae, Marine surveyor. Three types of cylindrical objects, which have noses of flat-faced, conical, and hemisphere, were used during the experiment. The measured noise exhibits a time-dependency which can be divided into three phases: (1) initial impact phase, (2) open cavity flow phase, (3) cavity collapse and bubble oscillation phase. In most cases, the waveform of bubble oscillation phase is dominant rather than that of initial impact phase. Pinch-off time, where a cavity begins to collapse, occurs at 0.18 ~ 0.2 second and the average lasting time of bubble was 0.9 ~ 1.3 second. The energy of water-entry impact noise is focused in the frequency region lower than 100 Hz, and the generated noise is influenced by the nose shapes, object mass, and launching velocity. As a result, energy spectral density on the bubble frequency is higher in the order of flat-faced, conical, hemisphere nose, and the increase of initial energy raises the energy spectral density on the bubble frequency in the cylinder body of same shape. Finally, we compare the measurements with the simulated signals and spectrum based on the bubble explosion physics, and obtain satisfactory agreements between them.

건축의례를 통해 본 전통주거의 공간구조와 의미에 관한 연구

정영철 한국주거학회 2001 한국주거학회 논문집 Vol.12 No.1

There were the rites and customs in building of the traditional houses. The purpose of this study is to search the meaning of the building rites, and to search the spatial structure and meaning of the traditional houses through the rites as establishing the true dwelling. The traditional houses show the oppositional structure of the sacred and profane through the rites and customs of the building as the communication with the gods and men. The traditional houses are the center of which the gods of four sides defined and have the cardinal points and vertical axis which has the mythical and symbolic meaning.

클로자핀으로의 교체와 관련된 지연성 운동장애 1례

정영철,이춘용,현웅 대한정신약물학회 2006 대한정신약물학회지 Vol.17 No.6

Objective: Clozapine is known as an atypical antipsychotic drug which has less side effects in the extrapyramidal system than typical antipsychotic drugs and recommended as a treatment of choice in severe tardive dyskinesia (TD). However, it has been reported that the existing TD was worsened or new TD appeared in some cases where the antipsychotic drugs were switched to clozapine. Methods: We experienced a single case in which TD was appeared in the tongue and jaw 5 months after chlorpromazine was switched to clozapine. Results: The subject was 57 years old male patient with bipolar disorder. He had been treated intermittently with lithium and chlorpromazine for over 30 years. Five months after switching from chlorpromazine to clozapine, TD appeared in the tongue and jaw. Using Extrapyramidal Symptom Rating Scale (ESRS), the dyskinesia score was 10. Hence, clozapine was stopped and chlorpromazine was re-administrated resulting gradual improvement of TD. The dyskinesia score of ESRS was dropped to 6. Conclusions: It is speculated that this case is most likely a withdrawal tardive dyskinesia but other possibilities should be considered too. The question “Does withdrawal tardive dyskinesia occur more easily when switched to clozapine which has a weak dopamine antagonism?” should be addressed in future study.
