The purpose of this study was to examine factors related to the oral health by stress in college women. This survey was conducted between June 16, 2014 and July 18, 2014 to investigate the correlation between stress and oral health Data were obtained from 393 women students of 5 colleges in Gwangju and Jeollanam-do. The oral health of college students is related with the stress which has a correlation between oral condition satisfaction(-) and inconvenient(+) of mastication and pronunciation (p<0.01). Also, factors affecting stress are discomfort during mastication and oral state satisfaction and discomfort during mastication. The discomfort during mastication showed the highest stress while the higher status of oral satisfaction showed lower stress (p<0.05). Therefore, college women stress is related with oral health. Colleges should consider developing a program which can appropriately manage and regulate stress to relieve their stress.

Background: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory reperfusion disorders. We investigated the influence of cerebral reperfusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. Materials and method: Anesthetized Sprague-Dawley rats were undergone ligation of both internal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of internal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. Result: The histopathologic damage scores were 0, 10.2±0.5, 7.6±1.5, 5.9±1.4, 5.0±2.8, 3.5±0.7, and 1.0±0.0 in control, 0, 10,20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). Conclusion: Our results showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion flow after incomplete forebrain ischemia. We believe restoration of reperfusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

본 연구의 목적은 chlorhexidine(Cervitec)과 fluoride(Fluor-protector) 성분을 각각 포함한 varnish를 치아에 적용하였을 때 타액내의 mutans streptococci의 수의 감소에 미치는 효과를 알아보기 위한 것이다. 전북대학교 치과대학생 40명을 대상으로 하여 mutans streptococci 균종 수를 평가하였으며, 이들을 무작위로 네 군으로 나누어 다음과 같이 varnish를 적용하였다; A) varnish를 적용하지 않은 군(n=10), B) chlorhexidine varnish 적용군(n=10), C) fluoride varnish 적용군(n=10), D) chlorhexidine과 fluoride varnish를 모두 적용한 군(n=10), Mutans streptococci 수 측정에는 Orion diagnostica 사의 Dentocult SM을 사용하였다. Varnish를 적용하지 않은 상태에서 1차로 Mutans streptococci 수를 측정한 후 각각의 varnish를 적용하였으며, varnish 적용 12주 후 다시 측정하여 기록하였다. 모든 실험군(group B, C, D)에서 12주 후에 측정한 Mutans streptococci 수가 감소한 개체가 증가한 개체보다 많았으나 통계적으로 유의한 차이는 보이지 않았다(p>0.05). 실험에 사용된 어떠한 varnish도 적용 12주 후에 타액 내 mutans streptococci 수에 통계적으로 유의할 만한 변화를 주지는 못하는 것으로 나타났다(p>0.05). The objective of the present prospective trial was to compare the efficacy of chlorhexidine(Cervitec), Fluoride(Fluorprotector) and combination of chlorhexdine and fluoride varnishes in decreasing the level of salivary mutans streptococci. Forty healthy students of school of dentistry, Chonbuk national university were investigated to evaluate mutans streptococci(MS) counts and randomized into four groups to treat with the experimental varnishes: A) untreated group(n=10), B) chlorhexidine group(n=10), C) fluoride group(n=10), D) chlorhexidine and fluoride group(n=10). Dentocult SM^(�)(Orion Diagnostica) strip method was used for measurement of the level of mutans streptococci in saliva. Stimulated saliva were collected at baseline for mutans streptococci counts evaluation(ms1), 12 weeks later the completion of each varnish treatment, mutans streptococci counts were re-evaluated. In varnish group with chlorhexidine, fluoride and combination of chlorhexidine and fluoride, the level of mutans streptococci was lower after 12 weeks than at baseline, but there were no significant differences in saliva(p>0.05), when compared with baseline. After 12 weeks, a remarkable reduction was still found in the subjects with high level of mutans streptococci at baseline, but not different in the low and moderate level of mutans streptococci(p>0.05).

Idiopathic thrombocytopenic purpura(ITP) is an autoimmune bleeding disorder characterized by the development of antibodies to one's own platelets, which are then destroyed by phagocytosis in the spleen and liver. Its clinical manifestations are characterized by bleeding and the most serious complication is hemorrhage into the central nervous system, but which is rarely seen below 1%. In treating IPT, the therapy of first chice is administration of adrenocorticosteroid and r-globuline. If satisfactory results are not obtained, then splenectomy is recommended. If this also proves inadequate, then administration of immunosuppressants is carried out. 16-year-old male was admitted with complaints of left hemiplegia and nasal bleeding. This case may be developed spontaneous intracerebral hemorrhage causing thrombocytopenia and was treated by steroid, r-globuline and splenectomy, but satisfactory results are not obtained. After all, the paient was successfully treated with cyclophosphamide.

랭보의 詩作品속에서 「물」의 이마쥬 : Memoire와 Larme를 中心으로

徐連善 慶尙大學校 1980 論文集 Vol.19 No.2

Chez Rimbaud, la creation poetique n'est jamais une activite marginale, une production "litteraire" aisement dissociable d'une situation individuelle. Son oevre doit au contraire se concevoir comme un progres, un approfondissement tout a la fois humain et litteraire. Apres le flot de furure et de violence que provoque le spectacle de la repression, Rimbaud finit par ecrire "lettre du VOYANT". Le nouvel objectif qu'on y voit est la VOYANCE et la nouvelle mothode est le "long, immense et raisonne dereglement de tous les sens". Rimbaud, qui condamne a l'avance ses "reves"(Ophelie) et qui, au moment or il experimente la theorie du Voyant, en decrit deja les desillusions (Bateau ivre), semble-t-il, va lentement constater ses illusions, la sterilite de son projet et douter en plus de sa force. Il est indiscutable que bien de ses oeuvres se ramenent a la femme et quelques unes desquelles relevent plus particulierement du probleme des rapports avec sa mere : fixation maternelle. La haine et le mepris qu'il glisse de la femme revient sur sa condamnation, sur la Societe rendue responsable de la condition feminine. Cete violence peut paraitre bien facile : il a bien le sentiment d'avor ete vole, d'avoir ete depossede. C'est qu'il range toutes incarnations de l'Ordre, toutes repressions de l'instinct, donc de la vie. Mer et riviere, larmes humaines et eaux de la nature se trouvent nettement divisees dans l' univers de Rimbaud. Nulle part la purification, cete fonction pourtant primordiale de l'ear, n'est associee a l'eau douce. Au contraire, Rimbaud la juge impure et indigne du poete. Rimbaud reduit le theme de l'eau a une essence simple, l'eau et les oppositions: eau et or, eau ou sokf servant en realite a etablir une comparasion entre deux joies et deux etats. La soif figure pour Rimbaud en quelque sorte l'appetit pri; satisfaire la soif et s'avandonner a la Nature, ce sont des gestes complementaire: des acceptations de la realite. La defense de boire atteint le poete dans sa faculte creatrice. Alors il rompre avec la riviere dans MEMOIRE. Dans LARME il confronte l'eau salee avec l'eau douce; C'est un adieu au bord de l'Oise, a l'eau de la riviere elle-meme: Jeune Oise, c'est la jeunesse intolerable du poete. Les pleurs et la mer, le deuil et les images maritimes s'associent tout naturellement chez Rimbaud. Leur amertumes les unit et le sel figure pour lui comme le cristallisation sensible de l'amertume. Degouts, larmes ou mer, ces themes aspirent en definitive a un seul but: la purification du poete. L'espoir en une nouvelle vie est indissolublement lie avec la revolte contre une societe dechue, etouffante. puisque le triste horizon familial et social d'ici bas l'a prive de l'amour humain, la valeur fondamentale dans cette "vrai vie" sera l'Amour universel. Malgre le desil constant chez Rimbaud de se resider dans un mouvement universel, de generaliser son entreprise, force lui sera de constater qu'il ne travaille pas fondamentalement pour l'humanite. L'entreprise du Voyant se fondait en effet sur des mouvements bien contradictoires. Rimbaud semble marquer qu'il n'a pu rencontrer cet "au dela" or reside peut-etre l'inconnu et qui suppose undegagement plus radical.
