Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

The purpose of this study was to investigate the distribution of CGRP immunoreactive nerve fibers in rat squamosomandibular joint with postnatal development. Squamosomandibular joint with adjacent tissue of 8 groups of rats(1,5,10,15,20,25,35-postnatal day and adult groups) were removed en bloc and processed for immunohistochemistry and were subjected to light microscopic examination. The results obtained were as follows; 1. The anterior portion of the articular disk was most densely innervated, followed by the posterior, lateral, and medial portions in each group. 2. Increase of CGRP immunoreactive nerve fibers was evident in 10,15,20 postnatal day groups. 3. Almost no CGRP immunoreactive nerve fibers were observed in articular surface of disk proper, mandibular fossa and condyle head of each group. These result suggest that CGRP immunoreactive nerve fibers increased in synovial membrane and peripheral portion of articular disk during 10-20 postnatal day may play a important role in squamosomandibular joint function after weaning period.

배진희,박효상,성재현 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.3

하악골의 성장은 골격적 요인이 동반된 III급 부정교합자의 치료의 결과, 예후에 중대한 영향을 미칠 수 있으며, 특히 성장기 환자의 경우 성장의 조절을 통하여 효과적인 치료를 기할 수 있으므로 개개인의 성장양상을 평가하기 위한 여러 방법들에 관하여 선학들의 많은 연구가 있어왔다. 본 연구에서는 하악골 성장예측의 지표로 경추골 성숙도를 이용한 골령평가법이 유용한 지를 알아보기 위해 1972년 Lamparski에 의해 제안된 표준 경추골 성숙단계를 이용하여 정상교합자 남자 18명, 여자 14명의 8.5세세서 18.5세까지 매 2년 간격으로 촬영한 측모두부방사선 규격사진 192매에 나타난 경추골 성숙도와 하악골 및 신장의 성장간의 관련성을 분석하여 다음과 같은 결론을 얻었다. 1. 8.5세에서 14.5세까지는 동일한 연령군에서 여자가 남자보다 높은 경추골 성숙단계를 나타내었다. 2. 동일한 경추골 성숙단계에 도달하는 평균연령은 일반적으로 여자가 남자보다 이른 나이를 보였다. 3. 일반적으로 경추골 성숙단계 3-4단계간에 하악골 및 신장의 최대성장이 일어났다. 4. 경추골 성숙도와 하악골의 성장간에는 일정한 관련성이 있어 경추골 성숙도를 하악골 성장예측의 지표로 사용하는 것이 가능할 것으로 생각된다. In order to investigate the possibility of using a cervical vertebral maturation indicator as a mandibular growth indicator, the relationship of cervical vertebral maturation and mandibular & body height growth changes was assessed in biennial serial lateral cephalometric raadiographs of eighteen korean male and fourteen korean female while they were 8.5 to 18.5 years old. The following results were obtained. 1. It was a reliable method to evaluate skeletal maturation by using cervical vertebrae. 2. In general, cervical vertebral maturation stages of females were higher than those of males at the same age and there were significant differences in statistics at the age of 10.5, 14.5. 3. The age of a female at the same cervical vertebral maturation stage were earlier than that of a male. 4. In the case of males, significant Ar-Gn increases were found between stage 3 and 4,5; Ar-Co increases between stage 4 and 5. 5. In the case of females, significant S-Gn and Ar-Gn increases were found between stage 3 and 4. 6. Significant body height increases were found between stage 3 and 4 in both sexes. 7. The peak velocity of body height and mandibular length was observed between cervical vertebral maturation stage 3 and 4 in both sexes. 8. The relationship between mandibular & body height changes and specific maturation state of cervical vertebra was found, therefore using a cervical vertebral maturation indicator as mandibular growth indicator is quite within realms of possibility.

배은현,고광진,장현구 成均館大學校 科學技術硏究所 1989 論文集 Vol.40 No.2

The effects of reduction ratio and purity on the superplasticity of Pb-62%Sn eutectic alloys were studied. The alloys of two values of reduction ratio(r=10 : 1, 25 : 1) and impurity content(alloy A : 0.075%, alloy B : 0.216%) were prepared to compare the flow stress and elongation at constant strain rate. Also, the effect of temperature on the tensile behavior and the structural changes of the surfaces were investigated. Larger elongations were achieved for more worked(r=25 : 1) alloys because of their finer equiaxed grains, and for more purified alloy A in which less impurities inhibit the grain boundary sliding. Maximum elongation of 2300% was obtained for alloy A at room temperature, r = 25 : 1 and strain rate, ε˙= 1.4 x 10 exp(-4)/s. Increase in temperature, caused increase in strain rate sensitivity and decrease in flow stress, which explains that atomic accommodation process and grain boundary migration arc more enhanced at elevated temperature.

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Endometriosis in the abdominal scar following cesarean section is very rare condition among the extrapelvic endometriosis. The frequency of abdominal wall endometriosis secondary to cesarean section is from 0.03% to 0.8% in some reports. It is difficult to diagnosed in spite of the typical symptoms. The typical symptom is aching swelling in the area of the surgical scar, which is influenced by the phases of menstruation. The definitive diagnosis is established by pathologic analysis. Surgical excision remains the treatment of choice. The majority of patients presented from 1 to 2 years after the precipitating operation. We experienced an unusual case of abdominal wall endometriosis presented over 10 years after cesarean section, who was admitted to our hospital complaining of recurrent left lower abdominal pain. So, we report this case with a brief review of the concerned literatures.
