외상에 의한 치아의 함입은 치아가 치조골 방향으로 변위되어 있는 상태이다. 함입성 탈구는 다른 유형의 탈구성 손상에 비하여 드물게 발생하고, 낙상에 의한 경우가 많으며, 소녀보다는 소년에서 호발하는 것으로 보고되었다. 치아가 함입되었을 때, 치수괴사나 유착, 치근흡수, 근관폐쇄, 변연골 상실 등과 같은 합병증이 발생할 수 있으며, 치아 경조직과 치아 지지조직 등의 손상이 동반되는 경우가 흔하므로, 예후를 예측하고 정확한 진단 및 치료계획을 수립하는데 어려움이 있다. 함입된 치아의 치료는 자발적으로 재맹출하기를 기다리거나, 교정적 견인 또는 외과적으로 재위치 시키는 방법이 있다. 이 증례는 외상으로 인하여 상악 좌측 중절치가 함입되었다는 주소로 내원한 6세 7개월 된 여아에서, 함입된 치아의 자발적인 맹출을 기대하였으나 맹출이 되지 않아서, 교정적으로 견인하여 맹출시킨 경우로 양호한 결과를 얻었기에 이를 보고하는 바이다. Traumatic intrusion is a type of injury that involves axial displacement of a tooth toward the alveolar bone. Its occurance is relatively rare compared to other types of luxation in permanent dentition. It is more common in boys than in girls, and most common etiology of intrusion is fallen down. Various complication may occur following traumatic intrusion, such as pulp necrosis, root resorption, pulp obliteration and marginal bone loss. In addition, traumatic intrusion is commonly combined with hard or soft tissue injuries. Therefore, it is difficult to establish proper treatment plan. Choice of treatment for an intruded tooth by trauma include waiting for spontaneous re-eruption, orthodontic repositioning, and surgical repositioning. In this case, we repositioned the intruded central incisor using orthodontic traction, in a six-year old girl, which failed to re-erupt spontaneously.

誘電體表面의 Corona損에 關한 硏究

徐在鎬,尹良雄 圓光大學校 1981 論文集 Vol.15 No.1

The more the transmission voltage goes up in the high voltage insulation, the more the phenomenon of the surface corona comes out. And in the system of the transmitting electric power, the loss of the space-corona has been considered, and there can be the loss by the surface-corona. We can not ignore the loss, and there was no still the evident examination and study about it. Now, in the space-corona brought by the over head transmitting cable(line), we have used Peeks sguare low(V-Vo)². The purpose of this study is three, one is undertaken in other to search for the relations between the Peeks sguarelaw(V-Vo)² and the loss of the surface-corona, another is to observe the experiment in relation of the dielectric Kinds, a third is in the surface of the dielectrics coated with sillicon oil, or not. By the result of this experiment, I can find that the loss of the surface-corona is like Peek's sguare law(V-Vo)²

The glass systems of SiO_2-Al_2O_3-B_2O_3-K_2O were fabricated with the composition of SiO_2 65∼76wt%, B_2O_3 20∼30wt%, Al_2O_3 0.3∼4.5wt%, and K_2O 0.5∼2.5wt% for mother glass of high frequency chip inductor. The glasses were prepared by quenching the melt from 1500℃ and analyzed by X-ray diffraction. The specimens were prepared with composites of ball milled glasses powder mixed with 0∼50wt% of alumina powder. After heat treating at 850℃∼950℃, sintering behaviors were observed by measuring the density of specimens as a function of temperature and the amount of alumina. Dielectric constants and dissipation factors were evaluated with HP-4192A as well as other crucial properties such as strength, softening point and thermal expansion. The density, dielectric constant and dissipation factor of specimen were 2.61g/㎟, 5.9∼6.2 and 0.0013∼0.0016 at 1㎒, respectively.

SLIS(Software License Integrated Solution) is composed of the 6 parts, Server Agent, Web Server, Client Agent, Client Manager, Service, and Install Shield. For the most part of the project is developed based on MFC platform except for the one, Client Manager, which is built on DDK(Driver Development Kit) and ASP. NET platform. Client Agent program installed on a customer's computer is implemented in 14 different classes. Its main function is able to limit and uninstall the purchased software by using teminateProcess. The purchased softwares expiration dates on customer's computer is being monitored by both Server agent and Client software itself. Client Manager hides the process of Client Agent program which shouldn't be killed by manipulating Process List in Kernel through DDK. To do this, Client Manager is internally implanted and registered in Windows Service to be ran as a part of windows system.

중추에서 Prostaglandin계가 Renin-angiotensin System에 미치는 영향

Role of prostaglandins on the renin-angiotensin system in the central nervous system was examined in normotensive and 2-kidney, 1 clip (2K1C) hypertensive rats. The experiment was done under thiopental (50 ㎎/㎏, IP) anesthesia. Captopril and indomethacin were injected into the right lateral cerebral ventricle. Arterial blood pressure and heart rate were recorded from the femoral artery. Intracerebroventricular (ICV) captopril (1 ㎎) caused a decrease in mean arterial pressure in both normotensive and 2K1C hypertensive rats. The depressor response to captopril was more sensitive in hyper-tensive rats than in normotensive rats. Indomethacin treatment (ICV, 200 ㎎) altered the depressor response to captopril neither in normotensive nor in hypertensive rats. These results suggest that the cardiovascular effect of renin-angiotensin system in the central nervous system may not be mediated via prostaglandin systems in normotensive and 2KlC hypertensive rats.

Background/Aims: First-line therapies against Helicobacter pylori, including proton pump inhibitors (PPIs) plus two antibiotics, may fail in up to 20% of patients. ``Rescue`` therapy is usually needed for patients who failed the first-line treatment. This study evaluated the eradication rate of bismuth-containing quadruple rescue therapy over a 1- or 2-week period. Methods: We prospectively investigated 169 patients with a persistent H. pylori infection after the first-line triple therapy, which was administered from October 2008 to March 2010. The patients were randomized to receive a 1- or 2-week quadruple rescue therapy (pantoprazole 40 mg b.i.d., tripotassium dicitrate bismuthate 300 mg q.i.d., metronidazole 500 mg t.i.d., and tetracycline 500 mg q.i.d.). After the ``rescue`` therapy, the eradication rate, compliance, and adverse events were evaluated. Results: The 1-week group achieved 83.5% (71/85) and 87.7% (71/81) eradication rates in the intention to treat (ITT) and per-protocol (PP) analyses, respectively. The 2-week group obtained 87.7% (72/84) and 88.9% (72/81) eradication rate in the ITT and PP analyses, respectively. There was no significant difference in the eradication rate, patient compliance or rate of adverse events between the two groups. Conclusions: One-week bismuth-containing quadruple therapy can be as effective as a 2-week therapy after the failure of the first-line eradication therapy. (Gut Liver 2012;6:434-439)

This paper is concerned about the hysteretic characteristics of the K-type braced frame. To investigate elasto-plastic behaviors and hysteretic characteristics of the K-type braced frame, the tests of the tubular braced frame of column yielded type and the angle braced frame of beam yielded type were carried out. The principal parameters used in experiments are the slenderness ratio of braces and the stiffness of beam to column. The experimental results are compared with the analyses of the hysteretic behavior, the deformation capacity, respectively, as well.

N/A Background : The adhesion of H. pylori to the gastric epithelial cells may be an essential step for the pathophysiology of various H. pylori-induced gastrointestinal diseases. The purpose of this study was to investigate the ultrastructural relation of H. pylori and gastric epithelial cells in their adhesion. Methods : Endoscopic biopsy of gastric antrum and body was performed from 15 patients (9 men, 6 women) with chronic gastritis and H. pylori infection. The specimens were processed for electron microscopy and observed with a transmission electron microscope (Hitachi H-600). Results : On the basis of morphological appearances, the adhesions of H. pylori to the gastric epithelial cells were categorized into three types, filamentous connection, adhesion pedestals and membrane fusion. Coccoid and undetermined forms adhered mainly by the filamentous connection, whereas the bacillary forms adhered primarily by the adhesion pedestals and membrane fusion. Conclusion : Various types of adhesion were associated with H. pylori and gastric epithelium. Further studies are needed to evaluate the influence of different types of adhesion to the pathophysiology of H. pylori.
