To study nosologically the Korean shaman's initiation sickness, 'Shin-Byong', the authors investigated 29 shamans with Symptom Check List-90-R(SCL-90-R) and questionnaire without visiting and interviewed 70 shamans using SCL-90-R, questionnaire and The Schedule for Affective Disorder and Schizophrenia-Lifetime(SADS-L). All shamans were located in Seoul. The results were as follows : 1) Among symptom groups of SCL-90-R, 'Shin-Byong' were associated with higher scores in depression, somatization, psychoticism and hostility group in descending order. 2) With DSM-Ⅲ-R classification, 87.2% of 'Shin-Byong' cases were mood disorders, Another 8.6% of cases were somatization and dissociative disorders and two disorders were related with dissociative phenomenon. Considering the diagnosis of manic episodes in this study, it seems to be a part of dissociative phenomenon, 'Shin-Byong' is the syndrome that is mainly composed of depression and disorders, which are related with dissociative phenomenon. 3) Shamans have teleologic thinking that 'Shin-Byong' is the phenomenon to receive spirits and diagnose intuitively. They think the main therapeutic method is recieving spirits, In conclusion, 'Shin-Byong' isn't a real disease entity but it is a shamanistic disease concept transformed during the shamanistic therapeutic process for depression patients with high dissociative tendency and dissociative disorder.

Relapsing polychondritis is an uncommon multisystemic disease which is characterized by recurrent episodes of inflammation and progressive destruction of cartilaginous tissue. The cause of relapsing polychondritis is unclear and suspected to be autoimmune pathophysiology. It involves cartilage of nose, vertebra, trachea, peripheral joint as well as structures of eye, heart, blood vessels or inner ear. Auricular chondritis is present in almost all patients, and multiple arthritis, nasal chondritis, saddle nose, eye involvement, laryngotracheal involvement and skin manifestations are also present. We report a case of relapsing polychondritis presented a arthritis with review of literatures.

Barrier Layer Effect on the Electron Transport of the Dye-Sensitized Solar Cells Based on TiO₂ Nanotube Arrays

Rho, Chul,Min, Ji-Hye,Suh, Jung Sang American Chemical Society 2012 The Journal of Physical Chemistry Part C Vol.116 No.12

<P>We have studied the effect of the barrier layer on the electron transport of dye-sensitized solar cells (DSSCs) based on TiO<SUB>2</SUB> nanotube arrays. The barrier layer of TiO<SUB>2</SUB> nanotubes, corresponding to the underlayer of the detached TiO<SUB>2</SUB> nanotube films, was ion-milled to reduce its thickness. The energy conversion efficiencies (measured by back-side-illumination) of DSSCs based on the TiO<SUB>2</SUB> nanotube films?whose barrier layers were ion-milled for 0, 10, 20, and 30 min?were 2.5, 2.7, 2.9, and 3.1%, respectively. The conversion efficiency increased significantly with reducing the thickness of the barrier layer without opening the bottom tips. The improvement of the conversion efficiency was mainly due to the improvement of the electron transfer efficiency by reducing the thickness of the barrier layer. Also, electrochemical impedance spectroscopy (EIS) analysis showed that the thickness of the barrier layer has a pronounced impact on the electron transport resistance of the cells. It was concluded that the electron transport is hindered considerably by the barrier layer.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2012/jpccck.2012.116.issue-12/jp211708y/production/images/medium/jp-2011-11708y_0008.gif'></P>

Eleven allozymes from sixteen species of Drosophila were analyzed by using horizontal starch gel electrophoresis in order to estimate genetic relationship among these species. All eleven allozymes were present in all sixteen species examined, and some commom alleles were also detected. The mean genetic identity between inter-and intra-subgenus Drosophila were estimated to be 0.16∼0.20, and 0.24∼0.28, respectively. The results showed that D. nigromaculata, which belongs to subgenus Drosophila, had closer genetic relationship to the species in subgenus Sophophora than to Drosophila. High mean genetic identity was also observed between subgenus Hirtodrosophila and Drosophila, and between subgenus Paradrosophila and Sophophora. Results of Nei's genetic identity test of the present data generally agreed with the previously known Drosophila classification establised based on the cytological and morphological characteristics.

In this study, pressure drop was measured in the pulse jet bag filter without venturi on which 16 numbers of filter bags (Ø140 × 850 ℓ) are installed according to operation condition(filtration velocity, inlet dust concentration, pulse pressure, and pulse interval) using coke dust from steel mill. The obtained 180 pressure drop test data were used to predict pressure drop with multiple regression model so that pressure drop data can be used for effective operation condition and as basic data for economical design. The prediction results showed that when filtration velocity was increased by 1%, pressure drop was increased by 2.2% which indicated that filtration velocity among operation condition was attributed on the pressure drop the most. Pressure was dropped by 1.53% when pulse pressure was increased by 1% which also confirmed that pulse pressure was the major factor affecting on the pressure drop next to filtration velocity. Meanwhile, pressure drops were found increased by 0.3% and 0.37%, respectively when inlet dust concentration and pulse interval were increased by 1% implying that the effects of inlet dust concentration and pulse interval were less as compared with those changes of filtration velocity and pulse pressure. Therefore, the larger effect on the pressure drop the pulse jet bag filter was found in the order of filtration velocity(Vf), pulse pressure(Pp), inlet dust concentration(Ci), pulse interval(Pi). Also, the prediction result of filtration velocity, inlet dust concentration, pulse pressure, and pulse interval which showed the largest effect on the pressure drop indicated that stable operation can be executed with filtration velocity less than 1.5 m/min and inlet dust concentration less than 4 g/m3. However, it was regarded that pulse pressure and pulse interval need to be adjusted when inlet dust concentration is higher than 4 g/m3. When filtration velocity and pulse pressure were examined, operation was possible regardless of changes in pulse pressure if filtration velocity was at 1.5 m/min. If filtration velocity was increased to 2 m/min. operation would be possible only when pulse pressure was set at higher than 5.8 kgf/cm2. Also, the prediction result of pressure drop with filtration velocity and pulse interval showed that operation with pulse interval less than 50 sec. should be carried out under filtration velocity at 1.5 m/min. While, pulse interval should be set at lower than 11 sec. if filtration velocity was set at 2 m/min. Under the conditions of filtration velocity lower than 1 m/min and high pulse pressure higher than 7 kgf/cm2, though pressure drop would be less, in this case, economic feasibility would be low due to increased in installation and operation cost since scale of dust collection equipment becomes larger and life of filtration bag becomes shortened due to high pulse pressure.

Reversible Symptom Aggravation by Intake of Taurine-Rich Foods in Patients with Venous Congestive Myelopathy: Controlled Case Series Study

Suh Dae Chul,Jeong Soo,Choi Yun Hyeok,Cho Su Min,Yun Su Young,Son A Yeun,Lim Young Min,Kwon Boseong,Song Yunsun 대한신경중재치료의학회 2022 Neurointervention Vol.17 No.2

Purpose Reversible aggravation of myelopathy symptoms was observed after the intake of taurine-rich foods in patients with venous congestive myelopathy (VCM) caused by a spinal arteriovenous shunt (SAVS), and the taurine-challenge test was applied to demonstrate an association between taurine and VCM. Materials and Methods The current study reviewed any aggravation history of myelopathy symptoms, including walking difficulty, after consuming taurine-rich foods among 133 consecutive patients with a SAVS from a prospective institutional database from June 2013 to February 2021. The type of taurine-rich foods, demographic data, arteriovenous shunt level, and follow-up periods were obtained. For the controlled taurine challenge test, Bacchus® (Dong-A Pharmaceutical, Seoul, Korea), a taurine-rich drink, was given to patients who fulfilled test criteria of recovered VCM (pain-sensory-motor-sphincter scale ≥2, improvement of spinal cord signal intensity on magnetic resonance imaging, and follow-up >6 months after SAVS treatment) to confirm the disappearance of such aggravation. Results Ten patients had an aggravation history related to food. Webfoot octopus, small octopus, squid, crab, scallop, and taurine-rich energy drink (Bacchus®) were related to such aggravation in patients with VCM. Aggravation appeared about 30 minutes after food intake followed by expressions such as ‘I could not walk and collapsed to the ground’ and usually lasted for about 3 hours, followed by a slow recovery after taking rest. Four patients who met the test criteria underwent the taurine challenge with Bacchus® and revealed no further symptom aggravation, suggesting that taurine did not affect patients after recovery from VCM. Conclusion The association between taurine-rich food and reversible symptom aggravation can appear in patients with VCM and disappear after VCM treatment. Aggravation of venous hypertension in the spinal cord is suggested as a mechanism but further elucidation is needed.

Synthesis of Soluble Host Materials for Highly Efficient Red Phosphorescent Organic Light-Emitting Diodes

Suh, Min Chul,Park, So-Ra,Cho, Ye Ram,Shin, Dong Heon,Kang, Pil-Gu,Ahn, Dong A,Kim, Hyung Suk,Kim, Chul-Bae American Chemical Society 2016 ACS APPLIED MATERIALS & INTERFACES Vol.8 No.28

<P>New soluble host materials with benzocarbazole and triphenyltriazine moieties, 11-[3-(4,6-diphenyl-[1,3,5]triazin-2-y1)-phenyl]-11H-benzo[a]carbazole and 11[3'-(4,6-diphenyl- [1,3,5]triazin-2-y1)-biphenyl-4-y1]-11H-benzo[a]carbazole, were synthesized for highly efficient red phosphorescent organic light-emitting diodes (PHOLED). Hole-transporting benzocarbazole moiety and electron transporting triphenyltriazine moiety, which are severely twisted each other enhance the solubility of those materials in common organic solvent. The improved solubility from this molecular design could be due to a reduced pi-pi stacking interaction, which gives a very uniform film morphology after spin coating of those materials. As a result, we obtained highly efficient soluble PHOLEDs combined with an evaporated blue common layer structure. The resultant red PHOLED exhibited the maximum current efficiency as well as external quantum efficiency values up to 23.7 cd/A and 19.0%.</P>

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.
