In the scope of a larger research project aimed at the development of new fiber reinforced cement composites with improved tensile strength and ductility, numerous single fiber pullout tests from different concrete matrix were performed Fiber debonding and pullout have a large influence on the tensile stress - crack opening behavior of fiber concrete. Both debonding and pullout depend on the quality of the matrix, as well as on the type and quality of the steel fibers, and the applied fiber volume content. In this paper, all fiber pullout tests were carried out using high strength twisted wire strand steel cords. The pullout behavior from plain matrix was studied. The w/c ratio of the mixtures, fiber length, embedded length influence the pullout behavior.

Arterial blood gas anlysis has been established as an important aid to diagnosis, therapy, and prognosis in pulmonary diseases. Authors analyzed the results of arterial blood gas analysis of 136 pulmonary disease patients requiring oxygen therapy at the emergency room. In patients with chronic obstructive pulmonary disease, the findings are consistent with respiratory acidosis, PCO₂being abnormally high in 53.3% of the cases and PO₂below 80mmHg in 88.9%. In patients with bronchial asthma, the PO₂levels were higher than ones with chronic obstructive pulmonary disease but the results of remaining parameters were essentially similar. The patients of lung cancer were significantly iincreased in pH, comparing with ones of other pulmonary diseases (p<0.005), and significantly fell in PCO₂comparing with ones of bronchial asthma (p<0.01).

최근 장기적이고 심각한 임상 증상을 유발하는 만성 활동성 EBV 감염증의 개념이 정립되면서 그 증례들이 보고되고 있다. 만성 활동성 EBV 감염증은 소아나 젊은 성인들에게서 주로 발생되며, EBV-VCA IgG, EBV-EA IgG의 수치가 높게 관찰되고, 지속적인 발열, 전신쇠약감, 광범위한 임파선비대증, 간비장비대, 범혈구감소증, 다크론성감마병증을 나타낸다. 이 질환은 환자의 임상소견, 혈액학적 소견, EBV 항체 역가 및 침범 장기의 EBV genome 검출로 확진 되며 치료로 항 바이러스 체제, 항암 치료, 골수이식술 등이 시도되고 있으나 아직 검증되어 있지 않다. 저자들은 불명열을 주소로 내원하여 중증 만성 활동성 EBV 감염증으로 진단된 증례 4례를 경험하였다. 한 례에서는 항 바이러스 제제를 추여 후 임상적, 혈액학적 호전을 보였으나 치료 20일째 발생한 세균성 복막염과 패혈증으로 사망하였고, 두 례에서 총 6회의 CHOP 항암치료와 자가조혈모세포이식을 시행 받은 후 현재까지 증상 없이 추적관찰 중이다. 지속되는 발열을 주소로 내원한 불명열 환자들에게서 EBV에 대한 검사를 시행할 경우 불명열의 원인을 규명하는데 하나의 단서를 제공할 수 있을 것으로 사료된다. Epstein-Barr virus (EBV) is one of eight human herpesvirus. Primary infection with EBV in childhood is generally asymptomatic or mild, however, often causes overt diseases such as infectious mononucleosis (IM) and lymphoproliferative disorder (LPD), the latter occursing in immunologically compromised individuals. Historically, EBV has been considered to be etiologically linked to human malignancies such as EBV genome positive Burkitt's lymphoma and nasopharyngeal carcinoma. Recently, however, another category of EBV-related disease, "chronic active EBV infection", has been made to describe persons without a clearly defined underlying disease. We report 4 cases of patients, presented with episodic fever of unknown origin (FUO), who were diagnosed as severe chronic active EBV infection. A combined application of serology for EBV and in-situ hybridization established the diagnosis of the EBV infection.

치주인대 세포의 교원질 생성에 대한 Substance P의 효과

전준영,최제용,경희문,성재현 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.1

Substance P는 교정력이 가해진 치아의 치주인대 중 인장력을 받는 부위에 많이 분포하는 neuropeptide 중의 하나이며, 또한 여러 조직에서 neurogenic inflammation을 야기하는 neuropeptide 중의 하나로도 알려져 있다. 그러나 중요한 세포의 단백기질인 교원질의 생성에 대한 Substance P의 효과는 잘 알려져 있지 않다. 따라서 이 연구의 목적은 배양 치주인대 세포에서 교원질 생성에 대한 Substance P의 효과를 평가하는 것이었다. collagenase-digestion method로 교원질 생성을 평가하였고 mRNA 수준에서 작용효과를 평가하기 위하여 Northern blot hybridization을 시행하였다. 이 연구는 또한 교원질 생성에 대한 prostaglandin과 gelatinase 생성도 포함하였으며 변성된 교원질의 분해를 평가하기 위하여 Zymography를 이용하였다. 비교원성 단백질, 교원성 단백질, 상대교원질에 대한 dose-dependent effect를 보면 Substance P는 비교원성 단백질 합성을 증가시켰으나 교원성 단백질 합성은 감소시켰다. 그리하여 총 단백합성에 대한 상대적인 교원질 생성을 나타내는 상대교원질은 7%에서 3.6%로 감소시켰다. 세포를 indomethacin과 동시에 처리할 때 substance P의 교원질 합성 억제효과는 나타나지 않았다. 이것은 Substance P의 교원질 합성 억제효과가 prostaglandin의 생성 때문이라는 것을 의미한다. Substance P의 교원질 합성 억제효과가 procollagen mRNA의 정상(steady-state)수준에 부합하는가를 평가하기 위하여 northern blot hybridization을 시행한 결과 Substance P는 α1(1) procollagen mRNA의 양적 변동을 일으키지 않았다. Substance P의 교원질 생성 억제효과는 전사이후의 어떤 단계에서 이루어지는 현상임을 나타낸다. 치주인대세포에서 gelatinase 생성에 대한 Substance P의 효과를 알아보기 위하여 zymography를 이용하였다. zymogram을 보면 Substance P는 치주인대세포에서 gelatinase 생성에는 아무 효과도 나타내지 않음을 알 수 있다. Substance P의 교원질 생성 억제효과가 치주인대세포에 대해 선택적인가 아닌가를 알아보기 위하여 MC3T3-E1세포를 이용하였는데 Substance P는 MC3T3-E1세포의 교원질 합성에는 영향을 미치지 않았다. 이상에서 Substance P는 인간의 치주인대세포에서 교원질 합성을 억제하였다. 이 효과는 procollagen mRNA와 gelatinase 생성의 정상(steady-state) 수준의 변화 때문이 아니라 prostaglandin 생성과 연관이 있음을 알았다. Substance P is one of the neuropeptide which presents highly in tension site of periodontal ligament during the orthodontic tooth movement. It has been also known as one of the neuropeptides which cause neurogenic inflammation in various tissues and organs. However, there is no report about the effect of substance P on major extracellualar matrix protein, collagen production. The purpose of this study was to evaluate the collagen production by substance P in human periodontal ligament cell, The collagenase-digestion method was used to evaluate collagen production and also used Northern blot hybridization for the evaluation of collagen mRNA level. This study also included in terms of prostanglandins and gelatinase production with respect to collagen production. For the collagen degradation, zymography was used to estimate denatured collagen degradation. Dose-dependent effect of substance P on noncollagen protein, collagen, and percent collagen was that substance P increased noncollagen protein synthesis, but decreased collagen systnisis. So the percent collagen, which determined by relative collagen production against total protein production, was decreased from 7% to 3.6%. This inhibitory effect of substance P on collagen production was disappeared when cells were treated concomitantly with indomethacin. It means that substance P-induced inhibitory effect on collagen production was due at least in part to the production of prostaglandins. To evaluate whether substance P-induced inhibitory effect on collagen production is correspond to the steady-state levels of procollagen mRNA, Northern blot hybridizartion was performed and it showed that substance P has no effect on the steady-state level of α1(1) procollagen mRNA. It means that the inhibitory effect of substance P on collagen production was due to the change of a certain mechanism after posttranscription. In this context, gelatinase production by substance P in periodontal ligament cells was evaluated by zymography. Zymogram showed that substance P has no effect on gelatinase production in periodontal ligament cells. To explore wheter substance P-induced inhibitory effect on collagen production is selevtive in periodontal ligament cells or not, MC3T3-31 cells which originated from mouse calvaria was used. It showed that substance P has no effect on collagen production in MCDTD-E1 cells. Taken together, substance P inhibits collagen production in human periodontal ligament cells. This effect was not due to the change of the steady-state level of procollagen mRNA and gelatinase production, but due at least in part to the change of prostaglandins production.

Everyone of human society has a obligation, a social morality and a social custom as a member of society. Also there is the law apart from these things. Men make a social norms for the purpose of keeping public order differently other animals. These social norms are compose of a religion, a morality, a custom and a law. These norms in human society have a certain role. And Institutions derive from form of material and immaterial in these norms. By the way, Utopia is the best form of these all norms. This paper concern these all norms in relation with Utopia. The range of the words Utopia is very great. Utopia is detailed descriptions of hypothetically perfect society. Example of this sort is Sir Thomas More's Utopia. Utopia is about how we would live and what kind of a world we would live in if we could do just that. The construction of imaginary worlds, free from the difficult that beset us in reality, takes place in one form or another in many cultures. Such images are embedded in origin and destination myths, where the good life is not available to us in this world. The contents are as follow; Chapter one, Introduction Chapter two, Human society and the problems of the law, Institution and Utopia. Chapter three, the types and conceptions of Utopia. Chapter four, the Utopia of Thomas More. Chapter five, conclusions.

『자연법과 일반의지에 관한 연구』 : J. J. Rousseau를 중심으로 With a Special Reference to J. J. Rousseau

전일주,이재현 진주산업대학교 1996 論文集 Vol.35 No.-

J. J. Rousseau was probably the most profound and influential political thinker of the eighteenth century. Rousseau was one of the major thinkers who regarded politics as the central determinant of human affairs. The structural components of Rousseau's political and law philosophy is his Natural law and General will. Natural law is one of the central themes in Western law and political thought. Current concern is focused on the issues of legitimacy, equality, right and duty, and community. Especially for Rousseau, the community is to prosper. It must be a unity whose wholeness that it acts only with respect to the whole. Rousseau considers the common interest as the factor of the prosperity of the community. One of the principal methods used to resolve these problems, until the end of the eighteenth century, was through the appeal to certain basic principles or values inherent in the human nature. Rousseau adapt natural law, the standard of justice as a guide to personal morality of the civilized man without abandoning the analysis of human nature. But Rousseau rejects the rook of the traditional natural law, but not the branch. Because the natural law is unnatural, the expericence of political life is the only philosophically valid explanation of the origin of human justice. For Rousseau, will is very important. The basis of will, Rousseau holds, is interest. The individual wills always what is for his interest. His interests conflict at many points with the interests others. But at some point the interest of all is the same. This common interest is what makes the state possible. The general will is but the expression of what the common interest requires. After all, the two terms of "general will" represent two main stands in Rousseau's thought. "Generality" stands for rule of law, for civid education that draws us out of ourselves and toward the general of common good. "Will" stands for Rousseau's conviction that to deprive you will of all freedom is to deprive your actions of all morality. Rousseau introduced the concept of the general will to elucidate the necessary and inevitable tension between the sovereign and the individual subject, whose private interest could speak to him completely differently than the common interest. The notion of the general will is thus a highly voluntarist formulation of the traditional conception of the common good or common interest. The idea of Rousseau's natural law and general will is the central doctrine of his political philosophy, which embodies his particular contribution to the modern political intelligence.

The purpose of this study was to investigate the characteristics of craniofacial morphology in adult with crowded dentition. The craniofacial morphology associated with normal and crowded of mandibular dentition was studied in lateral cephalometric radiograph obtained from 145 subjects grouped 44 males and 40 females in normal group, 33 males and 28 females in crowded group. The conclusions were as follows: Means, standard deviations and facial polygons from measurements were obtained from normal and crowded groups. Palatal plane to SN, occlusal plans to SN, mandibular plane to SN, mandibular plane to palatal plane and gonial angle measurements of crowded group were significantly different from normal group and were larger than normal group. SNA, SNB measurements of crowded group were significantly different from normal group and were smaller than normal group. Significant differences were observed between normal group and crowded groups on the basis of SN/1, PP/1, MP/1, and compared with normal group, upper incisors of crowded group were inclined more labially, whereas lower incisors of crowded group were inclined more lingually. Posterior facial height and ramal height were shorter in males of crowded group than those of normal group. Posterior facial height, mandibular length and posterior cranial base length were shorter in females of crowded group than those of normal group. Anterior facial height was longer in females of crowded group than those of normal group.

This research has incorporated a postal survey from the principals, nurse-charging teachers and nurse-teachers of the fiftyfive elementary, middle and high school in Yang-pyeong county area where its supplementary rate nurse-teachers is less than adequate. It is to analyse the current status of the school health service in the area and to come out with a plan to improve the school health program through the participations of the health related experts of the local community. The survey was done in the two months of periods of April to May of 1994. The result of the survey follows. The student population in the Yang-pyeong county area is 13,998 and the school employee population is 904 which counts for about 19.2% of the whole population of the area. However, the supplementary rate nurse-teachers is only 10.8% (4 in 5 schools) which is very low in terms of relativity. School health committee only exist in 17% of the whole number of schools in the area and 50 of school health commitee answered that their activity do not meet the adequate level. Only 54.3% of the whole school numbers has included the shool health finance in their financial plans and the amount set for school health finance is about 500,000 wons (100,000~1,600,000 wons). 64.9% of the schools in the Yang-pyeong county area have the permanent nursing room established in the school. But, often than the equipment for a simple physical examinations, their supply of the health related equipments are less than adequate. Particitations of school doctor in the school health service is at only 67.6% which pretty much include only the physical examinations. Nurse-charging teachers consider their utmost important role is to teach health education but, they answered that they spent most of their times and efforts on physical examinations & immunizations. The average number of students visition to the nursing room is 2.5 persons and complains for basic discomfort as headache, concussion, stomachache and indigestion problems and usual pills used are the analgesics and digestives. Physical examination is done in the most schools every year but, 51.4% of nurse-charging teachers answered the physical examination does not really help. About the emergency treatment ability, 75.7% reports that both manpower & equipment are short. The school food services are present in only 8 schools (21.6%) but, 89.2% of nurse-charging teachers answer that there is a definite need of the food service. The survey says that the utmost important environmental health and safety factors are the traffic accidents followed by improper heat system, lighting, the stools and desks that do not consider the student physical status. The overall evaluation of school health program reports that there are adequate physical examination, immunization, environmental hygiene, and management of safety but, on the other hand, health education, health councelling & management of nursing room are not managed properly. The principals of the survey pool report shortage of public agency support, lack of understanding of school health, shortage of nursing equipments and school health finance as the barrier factors of school health. The nurse-charging teachers report on the same questions as their less than qualitifying expertise, extraload of work upon the nursing affairs, shortage of nursing equipments & school health finance. The head masters & nurse-charging teachers answered that they are desperate for the meetings of nurse-charging teachers, construction of school health councelling system & training education in order to improve school health and if these are available, they will actively participate in them. After the careful analysis of the survey result, it is apparent that through thr relations of the manpowers, establishment of community-oriented school health is definitely in need rural area where there is low supplementary rate of nurse-teachers and poor school health environment.

L-라이신 발효에 있어서 당밀전처리의 영향

신현철,김성준,성진석,전영중,이재흥 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.3

Can molasses, the most widely used carbon source for the industrial fermentation of L-lysine, usually contains a high concentration of calcium ions which tend to cause scaling problem in the recovery process. To remove the calcium ions, cane molasses was pretreated with sulfuric acid by adjusting the pH to 2.5~3.5. When the pretreated solution was directly heat-sterilized and used in the fermentation, a significant reduction in L-lysine production was observed. In this paper, we proved that sucrose is a superior substrate for L-lysine fermentation of that of glucose or fructose and that the above-mentioned decrease of L-lysine production was caused by the hydrolysis of sucrose in the molasses when the molasses was heat-sterilized at a low pH. The problem was overcome by adjusting the pH of molasses to neutral before sterilization.
