홍후조,강익수,백경선 한국교육방법학회 2009 교육방법연구 Vol.21 No.2

This study deals with the problem of enlarging the kinds of courses of academic high schools by installing the ‘core’ school with particularized curriculum such as arts or physical education course tracks as well as academic tracks. For last 60 years Korean general high school have operated two tracks, humanities and social science track, and natural science track. Two traditional tracks did not meet the needs of students and society. Survey were administered to secondary school students and teachers, asking about the curricular needs of new tracks. Based on the results of questionnaires the simulation of allocating students and teachers, and installing facilities according to the curricular tracks was finished. About 30% of middle school graduates want to go to core high schools with particular track rather than traditional tracks.

K이 흡착된 Si(111)7×7표면에 대한 RHEED 연구

박종윤,이순보,이경원,안기석,신익조,강건아 성균관대학교 1990 論文集 Vol.41 No.2

상온 및 200℃∼600℃의 Si(111) 7×7 표면에 칼륨(K)을 증착하였을 때의 표면격자구조 변화를 RHEED로 관측하였다. K 증착시 Si(111)7×7 기판의 온도가 상온인 경우, 어느 일정한 증착시간(포화덮임률에 도달했다고 추정되는 증착시간)이 지난 후에는 원래의 깨끗한 Si(111)7×7 패턴과 유사한 Si(111) 7×7-K 패턴이 관측되었고, 증착시간을 증가시켜도 RHEED 패턴은 변화하지 않았다. 이것을 annealing하면 350℃까지는 RHEED 패턴에 변화가 없다가 그 이상의 온도가 되면 서서히 원래의 7×7 패턴으로 되돌아가기 시작한다. Si(111) 7×7기판의 온도를 200℃∼600℃로 유지하면서 K을 일정시간(450℃에서 3×1이 형성되는 증착시간)이상 증착시킨 경우에 250℃까지는 상온의 경우와 비슷한 형태의 변형된 7×7 패턴이 관측되고, 300℃∼550℃일때는 3×1, 550℃ 이상에서는 1×1 구조가 관측되었다. 이때 300℃∼550℃에서 형성된 Si(111) 3×1-K 구조는 450℃에서 1분 정도 annealing 하면 항상 Si(111) 1×1-K 구조로 상전이가 일어남을 관측하였다. Potassium adsorbed surface structures of Si(111) 7×7 surface at room and high temperatures(200℃∼600℃) were investigated by RHEED. Potassium adsorption on the Si(111) 7×7 surface to saturated coverage at room temperature changed the RHEED pattern of Si(111) 7×7 to Si(111) 7×7-K. Subsequent heating of the Si(111) 7×7-K surface above 350℃ results in a Si(111) 7×7 with desorbing K. The RHEED pattern of the K-adsorbed on the Si(111) 7×7 surface up to the adsorption temperature of 250℃ was the modified 7×7 pattern, quite similar to that of the Si(111) 7×7-K, observed at room temperature. The 3×1 structure was observed in the temperature of adsorption between 300℃ and 550℃. Regardless of the adsorption temperature, a phase transition always took place from the Si(111) 3×1-K structure to Si(111) 1×1-K after annealing at 450℃ over 1 minute.

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.

Proteomic analyses reveal that ginsenoside Rg3(S) partially reverses cellular senescence in human dermal fibroblasts by inducing peroxiredoxin

Ik-Soon Jang,Eunbi Jo,Soo Jung Park,Su Jeong Baek,In-Hu Hwang,Hyun Mi Kang,Je-Ho Lee,권요셉,Junik Son,HO JEONG KWON,최종순 고려인삼학회 2020 Journal of Ginseng Research Vol.44 No.1

Background: The cellular senescence of primary cultured cells is an irreversible process characterized bygrowth arrest. Restoration of senescence by ginsenosides has not been explored so far. Rg3(S) treatmentmarkedly decreased senescence-associated b-galactosidase activity and intracellular reactive oxygenspecies levels in senescent human dermal fibroblasts (HDFs). However, the underlying mechanism of thiseffect of Rg3(S) on the senescent HDFs remains unknown. Methods: We performed a label-free quantitative proteomics to identify the altered proteins in Rg3(S)-treated senescent HDFs. Upregulated proteins induced by Rg3(S) were validated by real-time polymerasechain reaction and immunoblot analyses. Results: Finally, 157 human proteins were identified, and variable peroxiredoxin (PRDX) isotypes werehighly implicated by network analyses. Among them, the mitochondrial PRDX3 was transcriptionally andtranslationally increased in response to Rg3(S) treatment in senescent HDFs in a time-dependent manner. Conclusion: Our proteomic approach provides insights into the partial reversing effect of Rg3 on senescentHDFs through induction of antioxidant enzymes, particularly PRDX3.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Background Acquired von Willebrand syndrome (AVWS) has not been investigated in Korean patients with Philadelphia chromosome-negative myeloproliferative neoplasm. Methods This study analyzed the prevalence at diagnosis and clinical features of AVWS in patients with essential thrombocythemia (ET), polycythemia vera (PV), prefibrotic/early primary myelofibrosis (pre-PMF), or overt PMF (PMF) diagnosed between January 2019 and December 2021 at Chungam National University Hospital, Daejeon, Korea. AVWS was defined as below the lower reference limit (56%) of ristocetin cofactor activity (VWF:RCo). Results Sixty-four consecutive patients (36 with ET, 17 with PV, 6 with pre-PMF, and 5 with PMF; 30 men and 34 women) with a median age of 67 years (range, 18‒87 yr) were followed for a median of 25.1 months (range, 2.6‒46.4 mo). AVWS was detected in 20 (31.3%) patients at diagnosis and was most frequent in ET patients (41.4%), followed by patients with pre-PMF (33.3%) and PV (17.6%) patients. VWF:RCo was negatively correlated with the platelet count (r=0.937; P =0.002). Only one episode of minor bleeding occurred in a patient with ET and AVWS. Younger age (<50 yr) [odds ratio (OR), 7.08; 95% confidence interval (CI), 1.27‒39.48; P =0.026] and thrombocytosis (>600×109/L) (OR, 13.70; 95% CI, 1.35‒138.17; P =0.026) were independent risk factors for developing AVWS. Conclusion AVWS based on VWF:RCo was common in patients with ET and pre-PMF, but less common in patients with PV in the Korean population. Clinically significant bleeding is rare in these patients.
