조성미,정옥란,이상욱 한국음성과학회 2004 음성과학 Vol.11 No.4

This study attempted to provide a spectrum analysis for quantitative evaluation of singing voice quality of singing students rather than the presence or absence of the singer's formant. The regression analysis was used to analyse the relationship between ringing quality, SPR, and SPP of singing voice of college student subjects majoring in music. This study measured singing power ratio (SPR) in 41 singing students. Digital audio recordings were made in sung vowels for acoustic analyses. Each sample was judged by 1 experienced singing teacher and 4 voice pathologists on one semantic bipolar 7-point scales (ringing-dull). The results showed that the SPR and SPP had significant correlations with ringing Quality. The SPR had a significant relationship with ringing quality on singing voice in singing students. The SPR can be an important quantitative measurement for evaluating singing voice quality.

Jo,Man-Hyun,Ham,In-ki,Park,Sang-kyu,Seo,Gwan-Seok,Han,Gyu-Heung,Woo,In-Shik 한국자원식물학회 2003 Plant Resources Vol.6 No.2

This study was conducted to develop the clonal propagation technique through in vitro culture using basal stem explants in Phalaenopsis hybrid grown in vitro. The highest frequency of protocorm-like body (PLB) formation was obtained when basal stem explants were cultured on VW medium containing 30g/L sucrose, 500 mg/L activated charcoal, 150 ml/L coconut water, 1 mg/L NAA, 5 mg/L 2iP and 2.5g/L gel rite. PLBs transferred to Hyponex medium were regenerated to plantlets. Plantlets transferred to plastic pots containing spagnum moss were developed and successfully acclimatized under greenhouse. The flower was bloomingly opened in plants regenerated from basal stem explants. The flower was not different from both mother plant and plant induced through clonal propagation of Phalaenopsis hybrid.

Effect of In-row Plant Spacing on Growth and Yield of Korean Native Allium wakegi Araki

Jo,Man-Hyun,Ham,In-Ki,Park,Sang-Kyu,Seo,Gwan-Seok,Han,Gyu-Heung,Woo,In-Shik 한국자원식물학회 2003 Plant Resources Vol.6 No.2

Allium wakegi Araki was grown at plant spacings of 5, 10, 15, and 20 cm to determine the effect of planting density on the growth and yield. Allium wakegi Araki plants grown at the 5 cm plant spacing had the lowest bulb diameter and bulb weight, while plants at the lowest density (20 cm spacing) had the highest bulb diameter, bulb number, bulb weight and fresh weight. In general, plants grown at narrower spacings produced significantly smaller bulb diameter and bulb weight, but resulted in the highest yields and plants per hectare and lower fresh weights per plant.

조선시대 향교 건축의 공간 구성 -기문 및 문헌자료를 중심으로-

조상순 ( Sang Sun Jo ) 한국동양예술학회 2012 동양예술 Vol.20 No.-

역사적 건축물은 시대에 따라, 다양한 모습과 형태를 갖추면서 변화하여 왔다. 문화재의 元形1)을 언급하거나 건축물을 수리할 때에는, 역사적 변화과정을 감안하여, 각 시대의 흔적이 유지되도록 하되, 완전성과 진정성을 고려하는 것이 중요하다. 향교는 고려시대부터 존재하여 온 대표적인 조선시대 건축이다. 이에 대한 연구는 다양한 시각에서 이루어져 왔으나, 대부분 현존하는 형태와 공간에 대한 유형학적 연구에 그쳤으며, 이의 원형과 변화 과정에 대한 고찰은 부족했다. 본 연구에서는 조선시대 전반에 걸친 문헌자료를 근거로 현존향교의 공간 구성이 ‘어떠한 과정을 거쳐 현재와 같이 정형화하였는가’에 대하여 고찰하여, 내재된 공간 구성의 기본 원칙과 변화과정을 체계적으로 살펴보고자 하였으며, 그 결과는 다음과 같다. 첫째, 문헌에 나타난 조선 전기(1530년대) 향교는 328개이며, 과반수인 65.6%의 향교가 邑治의 동쪽과 북쪽에 입지하였고, 읍치와의 거리는 5리 미만이 86.9%였다. 향교의 입지는 개인 주택, 사찰터 등을 사용하기도 하였으며, 경치가 좋은 곳에 자리하기도하였다. 좌향은 기본적으로 남향을 선택하였으며, 이는 조선 중기 이후에 향교 입지 선정의 기본 원칙으로 자리 잡았다. 둘째, 대성전을 중심으로 한 제향영역과, 명륜당을 중심으로 한강학영역은, 조선 전기 향교에서 하나의 공간에 존재하고 있었고, 조선 전기를 거치면서 현재와 같이 구분되었다. 특히 명륜당은 조선 전기를 거치면서 향교의 구성 요소로 자리하게 되었으며, 조선중기에 창건되는 경우도 있었다. 셋째, 두 영역은 전후 관계에 따라 소위 ‘前廟後學’과 ‘前學後廟’, 두 가지 유형의 배치로 구분된다. 後者는 이미 중국 宋代 지방 향교 배치에 적용되고 있어, 이러한 배치는 지방 향교가 갖는 보편적 배치 형태였음을 알 수 있다. 넷째, 開城 成均館2)이 후자의 배치를 갖고 있는 반면, 서울 成均館이 전자의 배치를 갖게 된 배경은, 서울 성균관이 유교적 예법을 강조하였기 때문이었을 것으로 추정된다. 서울 성균관과 같은 배치를 갖고 있는 전주와 경주의 향교는 이를 모방하여 건립되었음이 확인되었다. 다섯째, 경상도에 위치한 자인향교의 경우 조선 초 선산의 해평향교, 강릉의 연곡향교의 예에 따라 건립한 기록이 있어 경우에 따라 타 향교를 모방하였음을 확인하였다. 여섯째, 명륜당은 15c까지도 일반 향교에 보편화되지 못했으며, 이것이 제도화되어 정착되는 시기는 16c전후이다. 조선 후기에는 건물 간 배치 관계가 명확해졌고, 소위 ‘上殿下堂’의 원칙이 완성되었다. Historic buildings, depending on the era, while equipped with a variety of looks and shapes have changed. So, whenever we mentioned about its original68) form or repair it, under consideration of its historical process of change, we should pay attention to keep its traces of each periods and also consider its totality and authenticity. Hyang-gyo69) has existed since the Goryeo Dynasty(A.D. 918-1392) and it is a representative architecture of the Joseon Dynasty(A.D. 1392-1910). And researches about it has been made from a various viewpoints. But most in cases, it concentrated on its typological research on form and space of present state. And there was the lack of consideration for the originality and the process of change. In this study, based on literatures throughout the Joseon Dynasty, I have considered the process of change of the spatial configuration of current Hyang-gyo architecture. By this, I tried to examine systematically the spatial configuration of the basic principles and processes of change inherent. The results are as follows. The First, the number of Hyang-gyo of the early Joseon period(A.D.1530s) in the literature are 328. More than half of them are located eastern and northern area of village or city. And 86.9% of them are located within 2km``s distances. In some cases, Hyang-gyo located on past-residence or past-temple site, and basically they were set southward. The second, the shrine zone centered by Dae-sung-jeon and the school zone centered by Myung-ryun-dang was originally existed in one space in case of beginning period of Joseon Dynasty. And they divide into two zones during former term of Joseon Dynasty. Especially, Myung-ryun-dang start to exist during former term of Joseon Dynasty and in some cases, it was build first during medium term of Joseon Dynasty. The third, these two zones would be layout as two types. The one is front-shrine and rear-school and the other is front-school and rear-shrine. As the layout of the latter was already adopted in Chinese local Hyang-gyo during Song dynasty(A.D. 960-1279), so this type of layout could be a typical one in hyang-gyo. In case of the former layout, it was the unique one of Joseon dynasty. The forth, there are two Sung-kyun-kwan which are the top educational institutions in Goryeo and Joseon dynasty. But they have different layouts. And the reason must be a difference of emphasis on Confucian etiquette and the one of Joseon dynasty take a front-shrine and rear-school layout. In cases of hynag-gyo in Jeonju and Gyeongju have imitated the layout of Sung-kyun-kwan of Joseon dynasty. The fifth, in case of hyang-gyo in Jain, it imitated the hyang-gyo in Hae-pyong of Sun-san and the hyang-gyo in Yeon-gok of Gang-neung in early Joseon dynasty. And it means that there were some cases of imitations regardless of the area. The sixth, Myung-ryun-dang(a study building) was not being common until 15th century. And its institutionalization and settlement period is around 16th century. During late Joseon dynasty, the clear relationship between buildings was placed and the principle of ``upper-shrine & below-school`` was completed.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

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.

문화재란 문화가치가 있는 사물로서 국가 가 종교적·세속적 근거에 따라 특별히 지정 한 재산이다. 문화재는 그것이 구현하는 정신적 가치와 시각적 음향적으로 표현하는 수단으로서 그 나라의 독특하고, 다양한 주체성을 보존하는 중요한 매체이기도 하다. 그러므로 문화재는 한나라의 민족역사와 문화로서 과거의 모습을 통해 현재 그리고 나아가 미래를 연결시키는 하나의 매개체인 것이다. 또한 문화재는 그 지역민에게 향토사적 인 자긍심 및 연대의식을 고취시키는 동시에 나아가 한 나라, 세계적인 관심사로 여겨 야 할 것이다. 원적산 봉수대는 양산군청 소재지에서 북쪽으로 약 9.2㎞, 통도사입구 마을인 신평에서 남쪽으로 8㎞지점에 있다. 이 봉수대는 경상남도 기념물 제 118호로써 원적산봉수대 보존회에 의해 복원된 문화재이다. 즉 다른 지역의 문화재와 달리 잊혀 져가는 문화재의 재생을 통해 다시 태어난 문화재인 것이다. 원적산 봉수대 주변정비 기본계획의 목적 은 지역민의 자긍심으로 복원된 봉수대와 주 변과 접근로를 체계적으로 정비를 함으로써 접근성, 전통성, 보존성을 높이고자 한다. 특히, 문화재보호를 위한 제반 법규 및 현지여건에 부합하는 정비방향을 설정하고, 전문 인력과 관련문헌을 바탕으로 문화재 주변을 역사성과 주민친화성, 기능성, 관광성을 함께 갖춘 문화공간으로서의 미래지향적 문화재정비 계획을 추구하고자 한다.

白鼠에 있어서 肝吸蟲感染에 대한 獲得抵抗에 관한 硏究

趙星煥,朱炅煥,林漢鍾 고려대학교 의과대학 1984 고려대 의대 잡지 Vol.21 No.3

The development of acquired resistance in clonorchiasis was studied in rats experimentally infected with Chonorchis sinesis. The induction of acquired resistance was attempted by first exposing adult rats to 15 or 50 metacercariae of C. sinesis from naturally infected Pseudorasbara parva and then treated with praziquantel prior being challenged. The reinfection was performed at 1, 2, 4, and 8 weeks after elimination of flukes. Worm recovery rates and growth of the worms obtained from rats necropsied at 4 weeks after reinfection were compared to those of control group. End point titers of rat's serun were studied by ELISA at the time of reinfection and morphological findings of bile ducts were also studied by the light microscope. In other experiments, rats were infected repeatedly with 5 or 10 metscercariae at 1 week interval for 5 times. Animals were kills 4 weeks after the last exposure and the results were compared to a single infection of 25 or 50 metacercariae. Worm collection was failed in rats challenged with 50 metacercariae at 1 or 2 weeks after treatment. Worm recovery rates were 3.5 and 20.0% in rats reinfected at 4 and 8 weeks respectively after treatment, while 41.5% in control rats. In other experiment, 15.6%, 18.3% and 33.3% in worm recovery rates were obtained in rats, challenged with reinfections at 2, 4, and 8 weeks respectively after treatment of these rats initially infected with 15 metacercariae. Recovery rates were 50.0% in control group. Worm racovered in this experiment were found retarded in growth compared to control group. High end point antibody titers of the rat serum at the time of reinfections were presented by ELISA and it seemed too suppress maturation of the worms. Histopathological recovery of the bile ducts were not remarkable until 4 weeks after treatment and it may be contributed to reinfection as an another protecting factor. Multiple low dose repeated infection showed lower recovery rates compared to high dose single infection. Worm recovery rates of animals infected 5 times with 5 metacercariae were 11.0% and single infection on 25 were 53.0%. That of animals infected 5 times with 10 metacercariae was 13.0% compared to 41.5% of single infection of 50 metacercariae. In conclusion, the data presented in this study indicate that during the course of infection by C. sinesis acquired resistance is induced by preceding infection although complete protection may not be elicited.
