목적 : 요통환자에서 요통의 유무와 강도를 평가하고자 표면근전도를 이용하여 근육 활동성의 차이를 검증하였고 적외선체열촬영을 이용하여 제표면 온도의 변화를 측정하였다. 방법 : 요통환자군 16명과 대조군 16명에 대하여 요부에 부착한 표면전극에서 얻은 근전도 신호와 적외선체열촬영 결과를 비교하였다. 교란요인의 영향을 배제하기 위하여 연령과 성별 그리고 비만도에 따라 정상 대조군과 요통환자군을 짝짓기하여 각각 16명씩 선정하였다. 결과 : 정적표면근전도 실시 결과 우측의 경우 중앙값이 요통환자군에서 198.1 ㎶, 정상대조군에서는 161.3 ㎶로 통계적으로 유의한 차이가 있었고(p<0.01), 좌측은 요통환자군에서 194.2 ㎶, 정상대조군에서 180.5 ㎶로 유의한 차이는 없었다. 동적표면근전도 실시 결과 재신전시와 굴곡시 근전위의 비가 우측의 경우 요통환자군에서 중앙값이 1.12였고 정상 대조군은 1.39로서 두 군간에 유의한 차이가 있었고(p=0.027), 좌측의 경우도 요통환자군에서는 1.08이었고 정상 대조군에서는 1.21로 유의한 차이가 있었다(p=0.036). 적외선체열촬영결과 ΔT가 0.5 ℃ 이상의 차이가 있을 때 이상이 있는 것으로 정하면, 요통환자군에서는 16명 모두 이상자로 판정되었고, 정상 대조군에서는 16명중 3명이 이상자로 판정되어 민감도는 100 %, 특이도는 81.3 % 였다. 표면근전도를 이용한 요통의 진단은 민감도가 78.6 %이고 특이도가 72.2 %였으며, 적외선체열촬영은 민감도가 100 %였고 특이도가 87.5 %였다. 결론 : 이러한 결과로 볼 때 표면근전도 검사법과 적외선체열촬영은 요통을 간접적으로 평가하는데 도움이 되는 검사법이며, 적외선체열촬영이 표면근전도검사법에 비하여 보다 정확한 검사법으로 판단된다. Objectives : We studied the efficacy of surface electromyography(SEMG) and digital infrared theimographic imaging (DITI) in the assessment of low back pain both(LBP) Methods : We compared electromygraphic signals from electrodes placed in the lumbar area and the digital theimographic images in 16 LBPpatients and 16 control subjects. The LBP patients and the control subjects were matched for age, gender, and body mass index(BMI) to adjust for any confounding effects Results : In the static analyses of SEMG, median value was 198.1 ㎶ for the controls on the right side, and they were 194.2 ㎶ and 180.5㎶ on left side respectively. There was a statistically significant difference between the two groups on the right side(p<0.01), but not on the left side. In the dynamic analyses of the SEMG, the median values of the extension per flexion ratio of right side were 1.12 for LBP patients and 1.39 for controls. and those on the left side were 1.08 and 1.21 respectively. There were statistically significant differences in both sodes(p<0.05). The sensitivity and specificity were 100% and 81.3% in DITI, 78.6% and 72.2% in SEMG. Conclusions : These results indicate that SEMG and DITI are useful methods for indirect assessments of LBP, and that DITI is more sensitive and specific than SEMG.

이근배,이희성,전재수,최재득 생화학분자생물학회 1980 BMB Reports Vol.8 No.1

The five major fractions of histone from normal and myelocytic leukemia leucocytes were prepared by the procedure of Johns. Electrophoretic behaviors on acrylamide gels and amino acid composition of various histone fractions from normal and leukema leucocytes: were compared:: The results obtained were as follows 1. The yields of whole hisfome isolated from normal and : inyelocytic leukemia leucocytes recovered were 37.08㎎ and 58.64㎎ per lg packed cells, respectively. 2. A marked increase in the amount of fraction KAS (f2b) from leukemia leucocytes was observed. These events were apparently correlated with a parallel decrease in the fractions KAP (f1) and ARE (f3). The .amount of fraction fZa (GRK+LAK) was almost to those of corresponding fraction of normal leucocytes. 3. Amino acid analysis showed the fraction ARE (f3) from leukemia cells contained markedly greater amounts of e-N-monomethyllysine and e-N-dimethyllysine than that from the normal cells.

다이어몬드상 탄소 박막의 제작시 수소 가스의 영향

Diamond-like carbon (DLC) films have been prepared by a widely-used rf(13.56 MHz) plasma-enhanced chemical vapor deposition(PECVD) method using CH4 gas. The hydrogen incorporated in DLC films plays an important role of determining the film properties, but its exact role has not been clear. In this study, the effect of hydrogen on the growth and film properties of DLC has been examined by adding the hydrogen gas to the CH4 gas during deposition and by exposing the prepared films to the hydrogen plasma. As the content of additive hydrogen gas increases, the density and hardness of the film increase, but the growth rate decreases. The FTIR spectroscopy results show that the number of C-H bonds decreases with increasing the hydrogen gas. Also, the variation in the position of 'G' and 'D' peaks due to additive hydrogen, which has been measured by Raman spectroscopy, indicates the increase of sp3 fraction.

The aircraft production quality management system in Korea has been implemented to support the developmental phase of Korean aircraft industries, from overhaul of the aircraft and engines to development of military trainer aircraft. After the deletion of the Mil-Q-9858A standard in 1996, Korean aerospace companies established ISO 9001 and AS 9100 as their basic aerospace quality management system specifications. These quality standards were adopted in the same period of time by other leading international aircraft manufacturing companies. This paper presents a future direction on the improvement of quality management systems for Korean aircraft production company by considering (1) Korean governments strategy for the development of Korean aircraft production industries, (2) short and long term business plan of Korean aerospace industries, and (3) benchmarking leading international company's quality management systems.

발화이론과 화용론에 관한 연구

On constate que les travaux de pragmatique linguistique, d'analyse du dialogue et du discours font e´clater le domaine de la linguistique et interessent de plus en plus tous les proble`mes concerne´s par les proble`mes d'emploi du langage en communication. C'est pour ca qu'on a esquisse´ les courants des pragmatiques. Selon les diverses traditions, les pragmatiques contemporaines se distinguent par leurs methodologies. On a essage´ de saisir les courants de pense´e et d'analyse dont les me´thodologies des the´oriciens les plus influence´s ont contribue´ a` la pragmatique (aux pragmatiques). Benveniste a contribue´ a` jeter les bases d'une the´orie linguistique de l'e´nonciation et a` de´crire les proce´de´s linguistiques qui permettent la conversion de la langue en discours, son appropriation par le sujet parlant et l'inscription dans l'enonce de l'enonciateur et de l'e´nonciataire. Austin e´laborait les bases de la pragmatique par l'e´tude systematique de la relation singne-utilisateur. Selon lui, en accomplissant un acte illocutoire, le locuteur s'assigne un certain ro^le et assigne corre´lativement a` l'auditeur un ro^le comple´mentaire. Le ro^le social endosse par le locuteru est re´alise institutionnellement. Austin a montre´ que le langage est une sorte de vaste institution, comportant une panoplie des ro^les conventionnels correspondant a` la gamme des actes de discours socialement reconnus. Avec Austin, la pragmatique est reintegree dans le champ des etudes proprement linguistiques. Ducrot developpe les e´tudes de pragmatique linguistique, dont lorigine est a `situer principlament dans les travaux d'Austin sur les e´nonce´s performatifs et les actes illocutoires d'une part et de Benveniste sur le discours et l'e´nonciation. A la base de cette aproche linguistique, on trouve l'ide´e majeure que la langue ne fonctionnent pas comme un syste`me de signes, un code, dont chacun des termes recevrait sa valeur des diffe´rences ou oppositions qu'il entretient avec les autres e´le´ments de syste`me. Ducrot, en suivant Benveniste, fait au contraire l'hypothse que le sens d'un e´nonce´ fait obligatoirement re´fe´rence a` son e´nonciation, ou en d'autres termes, qu'il est sui-re´fe´rentiel. Pour lui, l'e´tude du idscours devient une etude du discours ide´al. Selon Ducrot, les actes illocutoires, la pre´supposition et les indicateurs pragmatiques sont compris conventionnellement dans la langue, il les ve´rifie par la valeur argumentative et la loi du discours. Searle regroupe les categories des actes illocutoires d'Austin. La reflexion sur les actes de langage est nee d'une opposition radicale aux conceptions vericonditionnelles de la signification en philosoophie du langage, insistant sur le fait que les actes des communication langagie`re visent la re´alisation d'actes sociaux(les actes illocutoires). La proble´matique des actes illocutoires s'est de´finie principalement comme des conditions ne´cessaires et suffisantes a` la re´alisation appropriee des actions langagie`res et des conditions ge´ne´rales garantissant la reconnaissance des intentions illocutoires dans la communication. La pragmatique conversationnelle vise la modelisation du dialogue. Le mode`le d'analyse va permette d'une part de mettre a` jour des faits conversationnels perinents qu'il n'aurait pas e´te´ possible de de´couvrir sans son utilisation, et d'autre part d'ouvrir des perspectives interessantes quant a` la description lingusitique du francais. La fonction d'anayse conversationnelle reside dans sa capacite´ a` de´crire des structures conversationnelles differentes permettant d'expliquer des comportements diffe´rencies chez les interlocuteurs. L'esquisse ci-dessus permet de comprendre que dans le domaine de la se´mantique, avec l'extension de la notion de convention, sont introduits les e´le´ments pragmatiques. Cela veut dire que le domaine de la se´muntique etend sans cesse.
