In these days, Korea has undergone various changes in every social aspect throughthe process of modernization. Especially in instituional and actual aspects, the family.and marriage have been changed greatly by the rapid urbanization and iudustrializatton,.and these changes have been investigated scientifically. This paper presents marital consciousness and actual behavior of 300 woman collegestudents in Daegu, and was surveyed comparing various parts-the humanities, natural·science and the arts. As for the basic attitude of marriage, they were positive in the need of marriage,,defined marriage as the second starting point of life. Also they put the aim of marriage,on mental value. As for the dating and purity before marriage, 84 percent of respondents assented tothe dating before marriage. And they thought it proper that the duration of datingwas one year to two years. The age of the first dating and the standard of sex moralstore significant. The part of the arts tended to be open, and the part of natural sciencewere conservative. As for the standard of spouse's choice, 84 percent of respondents wanted to have theright of priority they could choose their spouses for themselves. And they thought it·proper that the age of marriage was 25-year-old to 26-year-old, and the gap of maritalage was one year to three years. Ideal spouse's characteristic, home surroundings, and marital harmony were significant. Among various marital conditions, personality tended to to emphasized, and theatmosphere of family and masculine appearance were taken serious. As for a. spouses's job, professor or research occupation was popular. Compared withthe part of the arts, the part of the humanities and natural science were positive inpredicting marital harmony. Among various marital conditions, an only son, the eldest son, and an offspring ofa concubine tended to be evaded. The type of an ideal spouse was companionship.

Background: The clinical significance of the apolipoprotein E (Apo E) ε4 allele in vascular dementia (VaD) has been a subject of debate. VaD is the most common subtype of dementia in Korean population. Apo E allele frequencies were evaluated in Korean patients with VaD diagnosed by the Erkinjuntti criteria of subcortical vascular dementia and mini-mental-state examination(MMSE) in this study Methods: Forty patients participated in the study. 20 patients with VaD and 20 controls with no risk factors for stroke who had absolutely normal brain MRI findings The Apo E genotype was determined by the polymerase chain reaction (PCR) and allele specific hybridization using the Apo E typing test kit Results: The Apo E ε4 allele frequency in the VaD group was 20% and was not significantly different from those of normal controls (15%) The severity of dementia assessed by K-MMSE was not different between the VaD patients with Apo E ε4 allele and the VaD patients without Apo E ε4 allele Conclusions: These results did not show neither increased frequency of Apo E ε4 allele in Korean VaD patients, nor any differences in trends compared to control subjects.

This paper introduces a dynamic source routing protocol supporting asymmetric routes on mobile ad hoc network. For performance evaluation, average route discovery time, average data transfer time, average route recovery time and data reception rate were considered with several scenarios relating to connection pattern, moving scenario, usage of secondary route chche in intermediate nodes and periodic hello message interval. As the results, we found that the data reception rate increased as the node mobility went down and the number of maximum connections between nodes was reduced. In the case that secondary route cache was used in the intermediate nodes, the average data transfer time was decreased because the possibility of route discovery to destination node was increased. In addition, it was found that the hello message interval at 0.1 to 1 second was fairly good.

In this paper, we enhanced the existing DSR routing protocol for ad hoc networks with bidirectional link. In mobile ad hoc network, mobile nodes themselves have router capability. Thus, for communication between two mobile nodes, the routing protocol for route set-up is required. DSR routing protocol, which is one of famous mobile ad hoc routing protocols, has the following problem: when route error occurs, the sending data packets drop as route recovery is delayed. In order to alleviate such problem, we modified route maintenance process of the existing DSR protocol so that the route recovery time from route error was shortened. As the result of performance evaluation, it was found the route recovery time of the proposed routing protocol was about 12 times faster than that of the existing DSR protocol. In addition, the data reception rate was more than 90 % for mobile ad hoc networks with slow mobility.

In this paper, we evaluated two main QoS supporting routing protocol on wireless ad hoc network. 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 support service between source and destination becoming a very important issue. Of all routing protocols, DSR and AODV are very important routing protocol in MANET. So we simulated DSR and AODV QoS Routing Protocol Through simulation evaluation tool NS(Network Simulation) based on various environments.

Abstract - In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance victor 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 point 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 date 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 16.3% for 0 mobility-stop second case and 4.7% for 300 mobility-stop second case.

Abstract - In this thesis, we propose a QoS supporting method on wireless ad hoc-based active network for improving reliability. On the loss of route path, the existing DSR routing protocol has several problems with wireless network communication because of decease of data reception rate and increase of network load. The proposed method improves reliability of data transfer by using functions of active network. That is, by using functions of active nodes and active packets, the proposed method supports QoS with reservation transfer method that saves data packets on transfer at intermediate nodes with lost path and then re-transmit the packets after route reconfiguration.

Gilbert 증후군은 인구의 7%에서까지 나타날 수 있는 매우 흔한 증후군으로서 비진행성인 양성의 만성적 경과를 치하며, 간질환의 증상과 징후가 없는 경한 비포합형 고빌리루빈혈증이 특징인 일종의 체질적인 증상으로서 혈장 빌리루빈 농도에 대한 사춘기의 영향 때문에 10대와 20대에 자주 진단이 된다. 따라서 임상적인 중요성은 미약하지만 높은 빈도가 예상되는 점에 그 중요성이 부여되어야 할 것이다. 따라서 적정한 임상적 진단법으로 기왕에 소개된 열량제한 시험과 phenobarbital 유도 시험을 시행하고 이들의 진단적 가치를 알아보기 위하여 본 연구를 시행하였다. 1990년 7월부터 1999년 4월까지 충남대학교병원에 내원하여 HBsAg, IgG anti-HBc 및 anti-HCV가 음성이고, 간 초음파 스캔에서 이상이 없으며, 혈청 AST, ALT 및 AP가 정상인 비음주자에서 경한 비포합형 고빌리루빈혈증이 있는 14예의 환자들을 대상으로 ^(99m)Tc-DISID 스캔을 시행하였으며, 기저 치 총빌리루빈 및 포합형 빌리루빈 치를 측정한 다음에 하루에 400Kcal로 48시간동안 제한한 열량 제한 시험을 시행하였고, phenobarbital을 하루 60mg씩 5일간 투여한 후에도 각각 총빌리루빈과 포합형 빌리루빈 치를 검사하여 비포합형을 구하였다. 대상 환자들은 모두 14예로서 남자가 11예(78.6%)였고 여자가 3예(21.4%)여서 3.7:1로 남자에서 많았으며, 20대가 6예(42.9%), 30대가 역시 6예(42.9%) 및 40대가 2예(14.2%)로서 2,30대가 대부분(85.8%)이었다. 열량 제한 시험 후의 총빌리루빈 치, 비포합형 및 포합형 빌리루빈 치들은 평균 각각 5.5±2.7, 4.2±2.3 및 1.3±10mg/dL 로서, 시험 전 치들인 3.0±0.8, 2.2±0.8 및 0.7±0.4mg/dL 보다 유의하게(p=0.001, p=0.001, p=0.023) 상승하였다. 포합형 빌리루빈 치도 유의하게 상승하였으나 비포합형의 상승보다는 훨씬 낮아서 주로 비포합형이 증가하였다. phenobarbital 투여 중 설사가 발생하여 중단한 1예를 제외한 13예에서 열량 제한 시험 후에 상승하였던 총, 비포합형 및 포합형 빌리루빈 치가 phenobarbital 유도 시험후에는 2.0±1.1, 1.5±0.8 및 0.5±0.4mg/dL로서 열량 제한 시험 결과보다 유의하게 낮아졌고(p=0.00, p=0.000, p=0.001), 열량 제한 시험 전의 기초치들인 3.0±0.8, 2.2±0.8 및 0.7±0.4mg.dL 보다도 더욱 낮아졌으며 유의한 차이(p=0.001, p=0.02, p=0.005)를 나타내었다. 14예에서 시행한 ^(99m)-Tc DISIDA 스캔에서 9예(64.3%)가 정상이었고, 5예(35.7%)에서는 심장 및 신장으로의 간외 섭취가 3예였고, 60분까지 소장 배출이 없는 배설 지연 예와 담낭 수축 불량 예가 각각 1예 씩 발견되었다. Phenobarbital 투여시험에서 민감도가 열량제한시험에 비해 더 높았다(92.3%와 50.0%). Gilbert 증후군에서 1일 400 Kcal로 48시간의 열량제한 시험과 1일 60mg의 phenobarbital을 5일간 투여하는 유도 시험은 편리하고 유용한 임상적인 진단법으로 이용할 수 있다고 생각된다. 그러나 열량 제한 시험에서는 증가 기준의 통일이 필요하다고 유추되며 phenobarbital 유도 시험이 민감도가 더 높은 것으로 생각된다. Gilbert's syndrome is very frequent and benign chronic process characterized by mild, intermittent, unconjugated hyperbilirubinemia without any symptom and sign of liver disease. Previously intoduced caloric restriction test and phenobarbital stimulation test as two appropriate clinical tests had been examined and their diagnostic values were reevaluated. Fourteen patients with mild, persistent, unconjugated hyperbilirubinemia were included. Subsequently caloric restriction has been applicated by 400 Kcal/day for 48 hours and phenobarbital has been prescribed by 60 mg/day for 5 days. Therafter serum levels of total and direct bilirubin were measured. Most of the patients were third and fourth decade(85.8%) and male predominant. Each basal serum levels of total, indirect and direct bilirubin were 3.0±0.8, 2.2±0.8 and 0.7±0.4 mg/dL. After caloric restriction test, each levels were increased significantly to 5.5±2.7, 4.2±2.3 and 1.3±1.0 mg/dL(p=0.001, p=0.001, p=0.023). After phenobarbital stimulation test for 13 patients had been practiced, increased levels of each bilirubin after caloric restriction test were decreased significantly to 2.0±1.0, 1.5±0.8 and 0.5±0.4 mg/dL(p=0.000, p=0.000, p=0.001) and these levels were significantly lower than basal levels(p=0.001, p=0.02, p=0.005). The sensitivities of caloric restriction test were 85.7%, 50.0%, and 71.4%, 35.7%(1.0, 1.5 mg increase of total bilirubin and 1.0, 1.5 mg/dL increase of indirect bilirubin). The sensitivities of phenobarbital stimulation test were 93.2% and 92.3% at criteria of 1.5 mg/dL increase of total bilirubin and indirect bilirubin. On the diagnosis of Gilbert syndrome, caloric restriction test and phenobarbital stimulation test are convenient and useful diagnostic tools in clinical face. And also phenobarbital stimulation test has higher sensitivity than caloric restriction test. Furthermore, standardization of bilirubin increment would be necessary in caloric restriction test.
