채영래,한상익,백인호 大韓神經精神醫學會 1988 신경정신의학 Vol.27 No.4

This study was designed to investigate whether depressed patient showed increased plasma contisol level compared with nondepressed patients and to examine whether diurnal variation is preserved or flattened in depressed patients and whether diurnal variation itself could be a useful diagnostic procedure in depression. We studied also the possible relationship between the diurnal variation of cortisol secretion and the degree of symptomatic improvement with antidepressant administration in major depression patients. The results were as follows : 1) The value of serum cortisol levels checked before antidepressant administration were 8.44±4.89㎍/dl, 5.74±3.19㎍/dl, 3.18±3.54㎍/dl, 10.75±5.23㎍/dl at 12AM, 4PM, 11PM and 8AM respectively in endogenous depression group, and 6.39±3.29㎍/dl, 6.25±3.75㎍/dl, 2.74±1.85㎍/dl, 10.79±4.77㎍/dl respectively in control group. There were no significant differences in serum cortisol levels between both groups(Table 2). 2) In 31 endogenous depressives, 18(58.1%) maintained diurnal variation of cortisol level and 13(41.9%) showed flattened variation. However, of 16 control group(schizophrenics and dysthymic disorder patients), 11(68.8%) maintained diurnal variation of cortisol secretion and5(31.2%) showed flattened variation. As a result, the sensitivity, specificity and predictive value of diurnal cortisol test for endogenous depression were 42%, 67%, and 72% respectively 3) In 26 major depression patients, 11 patients who showed flattened diurnal variation of cortisol secretion had significantly high "agitative depression" factors of Hamiltion Rating Scale for Depression compared with 15 patients who maintained diurnal variation. 4) Among 15 major depression patients whose diurnal variation was preserved, 12(80.0%) showed marked improvement of depressive symptoms with antidepressant administration and 3(20.0%) did not. Among 11 major depression patients whose diurnal variation was disturbed, 6(54.5%) improved and 5(45.5%) did not. There were no significant differences in symptomatic improvement between two groups.

High Impedance Faults (HIF) present a source of threat to utilities customers and personnel. Arcing faults result in waste of energy and can damage property. Protection against these faults comes mainly from a moral point of view, i.e. improving safety to persons. High Impedance Faults are difficult to detect, when the impedance at the point of fault is high enough to limit the fault current to the unprotected region of conventional overcurrent devices. Numerous detection methods have been suggested for such fault detection. However, each detection method cannot detect all electrical conditions resulting from down conductor fault. Until now, the arc models used for modeling high impedance fault were proposed. But, these are not suitable for implementing in EMTP. This paper proposes a technique for modeling the high impedance fault in transmission line using the ZnO arrester which can be implemented within EMTP. The performance of the proposed model is tested under a variety of fault conditions on a typical 345[kV] korean transmission line system.

한국 중세시기 香徒의 존재양상과 성격

채상식 釜山大學校 韓國民族文化硏究所 2012 한국민족문화 Vol.45 No.-

향도 단계에서 신라통일기를 이어 고려중기까지는 향도를 주도한 사회계층은 상층 신분층과 토호층이었으며, 여기에 물론 다수의 민들이 동참하는 형식을 취했을 것이다. 그러다가 고려중기 이후 향의 사용이 보편화되면서 향도는 상당히 분화가 이루어져 민들도 독자적으로 향도를 결성할 수 있게 되었다. 고려말에는 매향이 해안지역에 한정되긴 했지만 상당히 보편화되었던 것도 이러한 사정을 말해준다. 물론 향도는 일차적으로 향을 매개로 한 신앙공동체로서 존재하였지만,일부 상당히 큰 규모의 경우는 향도를 주도한 세력들이 지역공동체를 대표하는 인물들이었기에 그 지역을 통괄하고 영향력을 행사하는 기능을 수행했을 가능성은 충분히 예상할 수 있다. 그렇다고 향도의 본질적인 성격을 지역공동체와 연결하는 것은 수긍하기 어렵다. 어떻든 향도는 불교의 신앙결사의 한 형태이며, 구성원들의 자발적인 참여에 의해 조직된 특징이 있다. 향도의 궁극적인 목적은 수행을 통해 解脫․涅槃에 이르는 것이었다. 아울러 향도는 造石․造像․造塔․造鐘 등 불교의 상징 조형물의 조성이라는 직접적인 목표를 갖고 있었다. 따라서 사업 추진을 위한 재원의 공동 마련이 핵심적 내용이었으며, 사찰에서 주관하는 각종 행사에 헌신적인 참여와 지원, 그리고 장기적인 念佛 수행의 계획 등으로 나타나기도 하였다. 이러한 향도는 고려후기를 지나 여말선초에 이르면 불교가 퇴조함에 따라 향도의 성격이 변질된다. 이러한 중에 일부 도서와 해안 지방을 중심으로 민간신앙적 요소와 미륵신앙이 결합한 埋香 신앙이 유행하였다. 곧 신앙공동체로서 향도의 기능이 유지되기도 하였다. 그러나 전반적인 추세는 성리학이 지배하는 사회 속에서 불교적인 요소를 탈각해가면서 본래부터 포용하고 있던 민간신앙만이 강조되는 방향으로 나아갔다. 곧 향도는 불교적인 요소는 사라지고 ‘祀神團體的’인 기능이나, 향촌사회의 상부상조하는 ‘契’의 성격을 갖는 존재로 변신하게 되었다. The first reference to the Buddhist associations, named Hyangdo(香徒), comes from the historical fact that Hwarangdo led by Kim Yu-Sin(金庾信) was called 'Maitreya Buddhist association(彌勒香徒).' Many historical researches are inclined to regard them as the local communities(or founded upon regional relation). This argument, partly, seems true in that it is one of their characteristics that they were based upon the local areas. However, what we should more take a look at is their characteristics in terms of the community of faith. The Buddhist associations were the religious groups that made use of junipers in the rituals. At first, no one but the royal family and aristocrats could use the junipers to perform the buddhist rituals, cures, and practice ancestor worships in the mountains. As the use of junipers had been generalized, however, the middle and even lower classes could qualify for the membership of these associations. In short, these groups took the form of the devout Buddhist groups. Their organization largely depended upon the voluntary participants. It was their ultimate end to enter Nirvana(解脫) by practicing asceticism, as well as, more directly, building up the buddhist monuments. Therefore, as for the members, securing the financial resources was as a major problem, and so, they tried to support and take part in all sorts of events hosted by the buddhist temples, and to design scheme for the practice of Buddhist invocation(念佛) in an effort to do this. These associations had changed in their characteristics as Buddhism was on the wane in transitional period from Goryeo to Joseon dynasty. Meanwhile, the faith of Maehyang(埋香) combined with other folk beliefs and Maitreya faith was brought into vogue, mainly in some islands and seaside areas. In conclusion, the Buddhist associations showed a trend of taking a step in the direction of stripping the religious tone of Buddhism off them and colouring strongly the folk beliefs that already little by little were accommodated, on the whole, as Neo-Confucianism was the dominant thought in the society.

高麗國新雕大藏校正別錄의 편찬과 자료적 가치

채상식 釜山大學校 韓國民族文化硏究所 2013 한국민족문화 Vol.46 No.-

『高麗國新雕大藏校正別錄』(이하 『교정별록』)은 현재 고려초조대장경, 북송장경, 거란장경 등이 다 없어진 상황에서 그러한 장경들의 모습을 더듬어 볼 수 있고, 또 해인사 소장 재조대장경의 조판 경위를 알 수 있는 역사적 자료이다. 그리고 『교정별록』은 守其를 대표로 하여 교감을 맡은 학승들이 오류를 철저하게 파악하여 교감한 것으로 대장경 연구에 중요한 서지학적 자료이다. 이와 같이 철저한 교감을 거쳤기 때문에 재조대장경은 불교학 연구에 있어서 세계사적인 가치를 지니는 것이다. 이러한 『교정별록』 편찬을 통해서 알 수 있는 대장경 연구의 몇 가지 사실과 특징은 다음과 같다. 첫째, 종래에 일본측 학자들은 명확한 이론적 근거도 없이 초조장경은 북송의 개보칙판장경의 복각에 불과하다는 주장을 하였다. 그러나 『교정별록』의 내용을 분석해 보면 초조장경은 국내에 전해 오던 많은 사본과 대비했으며, 일부는 고려에만 잔존하던 경전을 入藏하기도 하였다. 어떻든 『교정별록』에 의해 초조장경은 단순히 북송의 장경을 복각한 것이 아니라 근 70여 년에 걸쳐 국내에 전하던 불경들과 상호 교감하거나, 부분적으로 고려에만 잔존하던 불경들을 새로이 入藏하여 완성한 것임을 알 수 있다. 둘째, 현재 거란장경은 별로 알려진 바 없다. 그러나 거란장경에 대해서 는 별로 알려진 바 없었으나 재조장경에는 거란본에 의거하여 중국에서 이미 인멸된 『釋摩訶衍論』과 『玄文論』을 入藏했을 뿐만 아니라 고려초조본·북송본의 많은 오류를 교감한 내용을 담고 있다. 이를 통해 사라진 거란장경의 면모를 단편적이나마 알 수 있다. 셋째, 『교정별록』에는 守其 등의 교감자는 고려본, 북송본, 거란본 등을 동일시하여 교감한 것이 아니다. 교감을 할 때 國本(고려초조본)과 宋本이 오류가 있을 경우는 ‘去’, ‘刪去’라고 했으나 丹本이 오류가 있을 때는 ‘不取’라는 용어를 사용한 것으로 보아 거란본을 正本으로 삼아 세 가지 본을 상호 대조하였던 것으로 짐작된다. 결론적으로 말해 『교정별록』의 편찬은 목록작업과 함께 대장경 간행을 위한 기초작업의 의미를 갖는다. 이러한 편찬은 당시 몽고에 유린되고 있던 동아시아에서 고려불교 수준이 최고의 위치에 있었기 때문에 가능할 수 있었다. It is well acknowledged that Koryokukshinjodaechangkyochongbyollock(高麗國新雕大藏校正別錄) has been the historical text through which the contents of Koryochojodaejangkyong(고려초조대장경), Sung’s Tripitaka in Northern Sung(북송장경), and Kitan’s Tripitaka(거란장경) that have been disappeared up to this time and the detailed information of typesetting Jaejodaejangkyong belonged to Haein-sa temple could be supposed. It has been also known that Kyochongbyollock which the learned Buddhist priests headed by Suki(守其) published to correct the errors of Tripitaka has been considered as a bibliographically crucial text to the study of it. With Kyochongbyollock published, it can be seen that there arose some features or aspects of the study of Tripitaka. First, Japanese scholars of this area have argued that Chojodaejangkyong is nothing but an imitation of ung’s Tripitaka in Northern Sung. It is widely agreed, however, that it proceeded by comparing other versions of Tripitaka in Koryo and importantly, by including them remained only in Koryo as well. Second, Kitan’s version has been little known so far. But Jajojangkyong shows much of proofing-records of several versions destroyed in China and others in East Asia. This allows one to witness the fragments of Kitan’s version. Finally, proofreaders, like Suki, did not equal wight to each versions of Tripitaka but compared one to another on the basis of Kitan’s version. In conclusion, the work of Kyochongbyollock was a kind of fundamental project for the publication of Tripitaka Koreana. This is also suggestive of the Buddhism of Koryo at the highest level in that period.

成人 男子의 身體構成에 關한 硏究(Ⅰ)

蔡鴻遠,洪相完 慶北大學校 師範大學 體育學硏究會 1987 體育學會誌 Vol.15 No.-

The subjects were 6 male active adultmen(the range of their age was 30∼47 years old), and they were freshmen members in Graduate School of Dong-A University doctorate course majoring in physical education. Body compositions were calculated by body density obtained from skinfold thickness method and underwater weighing. The purpose of this study was to fine out statistical difference between two methods with T-test, and compare correlations among those variables. The conclusions were as followings; 1. Physical Characteristics. Body height and body weight were rather higher and heavier than the common same age group's. 2. T-test between body compositions obtained from skinfold thickness method and underwater weighing method. There were not significant differences between the values of body compositions calculated from two methods(|T|<2.57, p<0.05). 3. Body Compositions. ① % far was 12.50±1.24% (skinfold thickness method) and 17.53±3.26% (underwater weighing method). ② Supposing that two subjects' body weight were same, We could find that the lighter underwater body weight the smaller body density. ③ We could assume that the values of body composition obtained from underwater weighing method were more accurate than those from skinfold thickness method. 4. Correlations. ① There were very high positive correlations between height and fat(p<0.05), Fat/Height(p<0.05), LBM/Height(p<0.01), and LBM(p<0.001). There were very high positive correlations between body weight and % fat(p<0.05), Fat/Height (p<0.01), and Fat·LBM·LBM/Height(respectively p<0.001). Besides, there were positive and negative correlations between the other values, but not statistical significances. ② There were high correlations between triceps and % Fat, % LBM. ③ There were positive correlations between body density and % Fat, but not a statistical significance. ④ There were positive correlations between vital capacity and residual lung volume % Fat, Fat, LBM, Fat/Height, and LBM/Height respectively, but not statistical significances. ⑤ Between triceps(X) and % fat(Y'), We could calculate regression equation (Y')=0.561X+8.249(Sy.x=1.039, r=0.819, p<0.05), between triceps(X) and Fat/Height(Y'), Y'=0.467X+1.628(Sy.x=1.033, r=0.821, p<0.05), between triceps(X) and % LBM(Y'), Y'=-0.561X+91.755(Sy.x=1.038, r=-0.819, p<0.05), but, in other cases there were not statistical significances because either correlation was low or Sy.x was large.

Salvia 育種에 있어서 有用形質의 選拔을 爲한 基礎的 硏究

尙埰圭 대구효성가톨릭대학교 1981 연구논문집 Vol.23 No.3

This study was conducted to get the informations from salvia breeding with 15 varieties(three for tall group and six each for medium and dwarf). For this 12 vegetative and floral characters were investigatied. They were compared among and within variety group, and the genetic parameters and correlation coefficients were summmarized as follows: 1. As the results of variance analysis plant height, lateral shot numbers, days to flowering, floret numbers and spike length showed statistical significance among and within variety group and no significant were observed in leaf length, leaf width, cycle flower numbers, calyx diameter except no significance for vegetative characters within tall group. 2. Estimated heritability in broad sense for all of characters studied were high and genetic advance(%) form plant height, lateral shoot numbers, and floret numbers were high. It therefore appears that the selection form this three characters would be effective. 3.Highly positive correlations were observed among plant height, lateral shoot numbers and days to flowering each other. Calyx diameter had negative correlation and spike length had no association with three characters mentioned above.

방사선 조사를 받은 두경부 병소의 재건을 위한 유리피판술

Radiation therapy is an effective cancer treatment modality as a primary treatment in early cancer and as an adjuvant treatment in advanced cancer, especially in head and neck lesions, but it also causes irreversible chronic damages to overlying normal tissues that may lead to wound complications. As well, at the microscopic level, radiation injury causes both stasis and occlusion of small vessels. Therefore, surgical reconstruction of previously-irradiated lesions in the head and neck poses a great problem. Fifth-six patients with head and neck lesions underwent 57 microsurgical reconstructions between 1990-1998. Thirteen patients were irradiated before surgery. The previous radiation dose was 30∼75.6 Gy. The free tissue transfer was successful in 52 of the 57 microsurgical reconstructions(91.2%). The success rate was 92.3%(12/13) in previously-irradiated patients and 90.9%(40/44) in nonirradiated patients. Postoperative complications, such as flap loss, fistula, and infection, developed in 4 irradiated patients and 8 nonirradiated patients. Overall complication rate was 30.8%(4/13) in previously-irradiated patients and 18.2%(8/44) in nonirradiated patients. Although the failure rate of previously-irradiated patients was higher than that of nonirradiated patients, there was no statistically significant difference between them. Thus, free tissue transfers in patients with previously-irradiated head and neck lesions are suitable for one-stage reconstruction.
