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.

본 연구는 온라인 쇼핑몰 확산 과정에서 소비자에게 인지된 가격 할인 혜택과 인터넷의 강점인 정보 탐색의 용이성, 고객 개개인에 대한 개인화 서비스 등이 실제 소비자들의 온라인 사이트 방문과 구매에 미치는 영향을 선행 연구들로부터 도출하고, 이들 영향이 국내 온라인 도서 소비자의 방문 및 구매 선호와 어떻게 관련되는지를 조사하며, 그 결과로 온라인 서점의 수익 개선에 필요한 시사점을 도출하려는데 목적을 두고 수행되었다. 연구결과 정보제공과 개인화 추천 서비스의 두 가지 요인이 도서 구매 고객의 방문 선호에 영향을 미치는 변수였으며, 구매 선호에 영향을 미치는 변수로는 정보제공과 가격할인의 두 가지 요인이었다. 또한, 방문 선호는 구매 선호에 유의한 영향을 주었다. 이러한 연구결과를 통해 소비자의 인터넷 사용 경험이 쌓여감에 따라 온라인 서점의 경쟁우위는 가격보다는 정보의 중요성쪽으로 옮겨가고 있음을 확인하였다. The literature survey of online bookstores shows that consumer's visits to online bookstores and his/her purchasing decision to the sites are strongly related to three factors, price discounts, easy gathering of book information and personalized services. This paper surveys and analyzes how these factors affect consumer's visits and his/her purchasing decision in Korean online book market in order to improve the revenue of online bookstores. The results show that the selection of visiting online bookstores are mainly affected by the provision of book information and personalized services, and consumer's choice of purchasing sites are affected by the price discounts and the provision of book information, It is also shown that the consumer's choice for purchasing at a specific site are highly dependent on the selection of visiting online bookstores.

Decision makers in the taxation units are aware of the complexity of the tax imposition process and of the inadequacy of the routine evaluation methods. Especially, inappropriate evaluation methods may give rise a unreasonable tax. In the evaluation of an unlisted stock, we have to consider evaluation problem in relation to convert unlisted stock to value of the cash before everything else. In this paper, we review the evaluation methods for an unlisted stock according to the tax law and cover a wide range of its' subjects, and present a method to improve.

출생후 성장발육에 따른 흰쥐 유곽유두의 CGRP 면역양성 신경분포변화

이재문 慶北大學校 齒科大學 1996 慶北齒大論文集 Vol.13 No.-

출생 후 성장 발육에 따른 흰쥐 유곽유두의 신경분포 및 변화를 관찰하기 위하여 생 후 1,5,10,15,20,25,35일 및 완전히 성장한 흰쥐를 대상으로 calcitonin gene-related peptide(CGRP)를 이용한 면역조직화학적 방법으로 관찰하여 다음과 같은 결과를 얻었다. CGRP-면역양성 신경섬유들이 혀의 양측에서부터 유두 내로 진입하여 성장발육에 따라 그 분포밀도가 증가하다가 10일군부터는 상피의 직하방에 특히 풍부하게 분포하여 subepithelial plexus를 형성하고 있었다. 1일군에서는 CGRP-면역양성 신경섬유의 특징적인 양상인 염주알 모양이 명확히 관찰되었으나 그 이후로는 염주알 모양은 다소 감소하였고 하나의 선으로 보이는 경우도 있었다. 상피 내로 진입하는 CGRP-면역양성 신경섬유들은 5일군에서 드물게 관찰되었으며 teaste pore를 가진 성숙한 미뢰가 처음으로 관찰되는 10일군에서 그 수가 증가하여 출생 후 15일군에서는 상피 전반에 걸쳐 풍부하게 관찰되었다. 그러나 그 이후 20일군부터는 미뢰가 존재하는 trench wall의 하방 ⅔부위의 CGRP-면역양성 신경섬유는 감소하고 유두의 top surface와 trench wall의 상방 ⅓에 CGRP-면역양성 신경섬유가 제한적으로 관찰되었다. The purpose of this study was to investigate the distribution of nerves in the rat circumvallate papilla by each developing stage. The distribution of nerves in the rat circumvallate papilla were investigated by means of immunohistochemistry for detection of calcitonin gene-related peptide(CGRP). The results were as follows: CGRP- immunoreactive(IR) nerve fibers entered the base of the papilla laterally to from a subepithelial plexus. On the 1st postnatal day, the bead-like appearance, typical appearance of CGRP-IR nerve fiber, was seen but from the 5th postnatal day the bead-like appearance was seen less clearly and nerve fibers looking like a line were often observed. Mature taste buds having taste pores were first seen at the 10th postnatal day and then, increased markedly after this stage. CGRP-IR nerve fibers entering the epithelium were rarely seen on the 5th postnatal day but they increased in number on the 10th postnatal day, when mature buds having taste pores were firstly obserned and then on the 15th postmanal day, they were observed abundantly throughout entire epithelium. But from the 20th postnatal day, the nerve fibers in the lower two-third of the trench wall in which taste buds exist decreased but on the top surface and upper one-third of the trench wall the nerve fibers were observed limitedly.

The current study aims at determining the effect of fitness and suggesting basic information necessary for training the National Alpine ski team through comparing the uniform nature lumbar joint and a knee joint muscular function in 20 Alpine ski racers based on race results. We divided the group into A (National team) and B (National reserve team) groups, and we used the result obtained by a body component analysis programs such as In Body 3.0 and Biodex system 3, which were further examined statistically by SPSS/PC+ program. The difference of uniform nature lumbar joint and a knee joint muscular function from the race in each team was analyzed through Independent Samples t-test, and the results are as follows: 1. The uniform nature the absolute lumbar region of a protractor and the flexor muscular strength in National Alpine ski team was notably higher than that of National reserve team, but there was little difference in relative vague per weight. 2. The uniform nature of lumbar region muscular stamina of National Alpine ski team was comparatively higher than that of the reserve team, but there was little difference in rate of muscle. 3. The average power of uniform lumbar region in National Alpine ski team showed a sizable difference at 60 degrees per second (p〈.01), and at 180 degrees per second there was a sizable difference between groups (p〈.01). 4. The left and right protractor of uniform nature knee joint and maximum muscular strength in National Alpine ski racers was notably high, but there was little difference in relative value per weight. 5. The uniform nature left and right of protractor and muscular stamina flexor knee joint in National Apline ski racers was notably high (p〈.01), but there was little diffrence between groups in muscular stamina of the right flexor. 6. The rate of muscle of uniform nature knee joint and the rate of muscle of both of National Alpine ski racers was not much different from that of National reserve team. 7. The average power of the left and right protractor and the uniform nature knee joint of flexor of National Alpine ski racers at 60 degrees per second was notably high (p〈.01). However, though the average power of the left and right of protractor and the right of flexor was notably high at 180 deg per second (p〈.05) there was little difference in the left flexor.

Using the sludge water in producing ready mixed concrete, which is generated as washing surplus concrete after completing manufacturing and transportation of concrete is the best method in meeting the issue of cost of production and environment. However, in reality, using sludge water decreases Quality, and solid ingredients adhere to the transportation line of sludge water and the basin of sludge water, agitated to prevent precipitation of sludge, which incurs tremendous amount of repair expenses. In order to resolve the problems above, we have studied stable methods of supplying sludge water and experimentally reviewed the types of facilities. The result showed that a facility that added stabilizing agents which retarded hydration of unhydrated cement in sludge water for certain periods (2-3 days) and simultaneously agitated and moved by air diffusion and vertical flat blade impeller was most effective in stabilizing concentration of solid and preventing precipitation of solid in the bottom of basin. In addition, the performance of agitation and prevention of adherence of reaction basin of sludge water depended on selective efficiency of sand grain, and it has been studied that buffering inconsistent band of circulation of sludge water by operating the ring blower for air diffusion to the maximum was advantageous to preventing managing concentration and prevention of adherence.

Pressure Swing Adsorption을 이용한 공기의 산소 농축에 관한 연구

문제권,이한주,이인규 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.2

This study is to analyze a pressure swing adsorption process in packed beds with 5A molecular sieve zeolite for production of oxygen rich gas from air. The experimental unit employed consists of two fixed beds and a purge tank and it is operated cyclically. Product oxygen concentration was monitored experimentally at varying adsorption and desorption pressure, degree of recovery and feed flow rate. To determine the optimum cycle time and the bed length, mass transfer zone (MTZ) concept was adapted. It was found that the optimum bed length is about twice the MTZ length under steady state operation. As the cycle is repeated, the oxygen concentration in the product is increased slowly until a-stable concentration is reached. Also, as the adsorption pressure is increased and/or the feed flow rate is decreased, the product oxygen concentration is increased. But the rate of concentration increase became rather small when adsorption pressure is increased to above 3 atm. When the saturated bed is depressurized to a subatmospheric pressure with a vacuum pump, this process can generate up to 89% of oxygen from air but the recovery of oxygen is rather poor.
