유치 및 초기 영구치의 치수신경분포 및 변화를 평가하기 위하여 교정치료를 위해 발치한 치근흡수가 비교적 적은 유치,정상 탈락기의 유치,맹출중인 교합하지 않은 제 1소구치,맹출이 완료되어 교합하고 있는 1소구치를 대상으로 neurofilament protein(NEP)을 이용한 면역조직화학적 방법으로 관찰하여 다음과 같은 결과를 얻었다. 치근흡수가 비교적 적은 유치에서도 영구치와 유사한 신경총의 존재와 신경분포 형태가 관찰되었으나,영구치에 비해 그 신경분포 밀도가 낮았으며 분지형성 또한 미약하게 나타났고,전상아질로 진입하는 섬유의 수가 적었다. 정상탈락기의 유치에서는 신경의 변성으로 소포(vesicle),단절(fragmentation)등이 관찰되었으며,그 신경분포가 현저히 감소되어 나타났고,총상의 형태도 소실되었다. 교합하지 않은 제 1소구치에서 치수내의 신경은 말단가지의 숫자가 적고,치수 조상아 세포 경계에 도달하였으며,비교적 가는 신경 섬유가 많았다. 교합하고 있는 제 1소구치에서 치수내의 신경은 말단이 조상아층으로 진출하고,어떤 신경섬유는 전상아질층까지 진입하였으며,비교적 굵은신경 섬유의 분포가 많아졌다. The purpose of this study was to investigate the distribution of nerves in the dental pulp of early extracted primary teeth,normal exfoliated teeth,partially-erupted,nonfunctional,premolars,and erupted,functional,premolars.Numbers of sample were 10 teeth in each group. The distribution of nerves in the dental pulp were investigated by means of immunohistochemistry for detection of neurofilament protein(NFP). The results were as follows: The early extracted primary teeth exhibited patterns of innervation similar to those observed for young permanent teeth.The plexiform arrangement of fibers was not evident in the primary teeth.Most nerves appear to terminate about the odontoblasts. As primary teeth began to undergo root resorption,degenerative changes such as vesicles and fragmentation appear in nerves.The quantity of neural tissue also decreased.In teeth in which the roots were almost completely resorbed only a small number of nerves remain. There was a decrease in the number of terminal branches in the pulp of the partiallyerupted,nonfunctional,premolars and those present reached the pulpo-odontoblastic border. The nerve terminals in the pulp of the erupted,functional,premolars were traced to the dentinal tubule and a few nerve fibers formed loops in the predentin.

The effect of Carbontetrachloride administration on Lactatedehydrogenase isozyme patterns were analyzed by cellulose acetate electrophoresis for the brain, heart, kidney, lung, liver and mouse muscle. Each other tissue was found to have a characteristic distribution of these isozymes. At normal condition, aerobic tissue such as brain, heart, kidney, and lung were found to have all five isozymes from LDH_1 to LDH_5, while anaerobic tissues such as liver and muscle were found to have superiorly LDH_5 The toxicity of Carbontetrachloride administration was most prominence in the liver, and lung toxicity was occured also.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

This research studied the characteristics and applicability of electrocoagulation using aluminium electrode for the color and COD removal in textile wastewater. Electrocoagulation reactor used two different electrode, Fe and Al, since in the general chemical wastewater treatment, aluminium and ferrous salts were used as coagulants. Aluminium electrode showed higher removal efficiency of color and COD than ferrous electrode did. The COD and color removal efficiency improved at the 0.192A/dm^2 current density. Thus, the electrocoagulation process with bipolar aluminium electrode showed better efficiency in the decolorization and COD removal rate of textile wastewater effluent than custom coagulants did.

We investigated the crystalline behaviour in active ion implanted by Secondary ion mass spectroscopy (SIMS) and Raman spectroscopy. The implantation-induced amorphization of damaged layer was clearly observed via the evolution,with increasing fluence of the broad four-band continuum of amorphous Si which extends from zero up to ??. For the samples annealed wsing rapid thermal annealing(RTA) after an isochronical anneal(30 min.) and isothermal anneal(450 ℃) of samples implanted with As to a dose of ??, the simple line spectrum of cystalline Si was recoved. The sharp c-Si Raman peak at ?? decreased and broad a-Si to peak centered ?? predominated as the implantaton does was increased. To describe the amorphous-crystalline transition stucture was used RNM and SCM models. We found that peak center and width dramatically change between ?? and 300℃ suggesting their is a large stuctural change in this temperature range.

PCS(Personal Communications Systems) where the cell structure is microcell can accommodate more subscribers than those of cellular systems where the cell structure is macrocellby reducing the cell fadius. To cope with such differences in PCS environment, new channel allocation and handover shcemes for PCS are needed. In this paper, problems which may arise when channel allocatio scheme of cellualr is applied to PCS is firstly analyzed. To overcome such poblems, a new schem is proposed. Also, a new handover scheme for PCS is propsoed. Performance of propsoed schemes is analyzed and compared with other channel allocation schemes and handover schemes. Blocking probability and forced call termination probability are used as performance parameters.

적 공간에서 퍼지 불확실성 틀에 관한 대안

문경일,이영천 호남대학교산업기술연구소 1997 산업기술연구논문집 Vol.4 No.-

모든 불확실성 이론들은 수리적인 uncertainty 측도를 정의하며, 측도들은 공리적인 접근방법을 사용하여 구축되거나 Shannon에 의한 엔트로피 모형 또는 그와 유사한 관련 모형들에 의해 구축된다. 특히 Shannon에 유사한 엔트로피 모형의 사용은 uncertainty의 할당에 따른 특정 정보의 복잡도에 관해 아주 자연스러운 의미를 제공하고 있다. 퍼지이론의 가능성 모형에 있어서 이러한 해석들이 현재 시도되고 있다. 본 논문은 이러한 이론에 관해 정보론적인 의미를 제공하고자 하는 데 있다. 특히 독립성이 결여되고, 교호작용의 가능성이 있는 적공간에서 possibilistic uncertainty을 나타내고, 퍼지영역으로부터 선택들이 채택 가능성을 식별할 수 있는 정보의 기대값으로서 possibilistic uncertainty를 나타낸다. All theories of uncertainty permit defining numerical uncertainty measures. These can originate by axiomatic approach or by modifying either Shannon or related entropy model. In particular, related entropy model has a very natural semantics as the complexity of transmission of specific information about the uncertainty assignment. Such interpretation has been established in the possibility model, based on fuzzy set theory. This paper presents such information semantics for this theory. Also, possibilistic uncertainty is suggested in the product space considered dependent and interacting. It is accomplished by demonstrating that possibilistic uncertainty can be viewed as the maximum value of information identifying the acceptability of choices from the fuzzy domain.
