본 연구는 정보사회의 모바일환경(Mobile-environment)에서의 삶의 질의 개념을 정의하고 구성요소를 파악하여 측정모형(measurement model)의 타당성을 검증하였다. 본 연구에서의 삶의 질의 개념은 삶의 주체인 인간이 환경과의 상호작용을 통해 삶을 영위하는 과정에서 느끼는 '주관적 삶의 질(Subjective quality of life)'로 정의하였으며, 이를 '개인과 환경과의 적합성(Person-environment fit)'을 통해 측정하였다. 본 연구는 모바일 환경에서의 삶의 질 측정척도를 개발하기 위해 2차례의 예비조사를 거쳐서 최종적으로 본조사를 실시하였으며, 이를 통해 개발된 8개의 삶의 질 차원과 차원별로 최종선정된 측정항목 38개를 가지고 각 차원별로 측정항목들간에 존재하는 명확한 단일차원성(unidimentionality)을 확인하고 구성개념 타당성(construct validity)를 평가하기 위해 AMOS 5.0을 활용하여 확인적 요인분석(confirmatory factor analysis)을 실시하였다. 한편 지표구성 항목에 대해 타당도를 확인하고 구성항목 간의 내적일관성을 파악하기 위해 알파신뢰도계수(Cronbach α-reliability coefficient)를 산출하였다. 또한 부가적으로 성별과 이동통신이용 만족도에 따른 삶의 질 수준의 차이를 검증하기 위해 이원분산분석(two-way ANOVA)을 하였다. 분석결과를 요약하면 다음과 같다. 첫째, 모바일환경에서 삶의 질의 구성요소는 7가지, 즉 사회성, 여가문화, 기능성, 안전성, 경제성, 건강성, 자율성으로 밝혀졌다. 둘째, 구성요소의 개념에 따른 각 측정항목을 이용하여 확인적 요인분석을 하여 얻은 측정모형의 전반적 적합지수는 ×2, RMR, GFI, AGFI, NFI의 기준에 비추어 볼 때 대체로 평가기준을 충족시키는 것으로 나타나 모바일환경에서의 삶의 질의 측정모형으로 적합한 것으로 판단되었다. 부가적으로 이동통신이용 만족집단이 불만족 집단보다 여가문화, 기능성과 관련한 삶의 질 수준이 더 높다는 것과 남자가 여자보다 이동통신이용 만족도와 기능성측면에 있어서의 삶의 질에 더 관계있음을 보여주었다. 이와 같은 연구결과는 모바일환경에서 삶의 질의 구성요소와 측정모형을 체계적으로 분석하고 잠재변수(구성개념construct)들을 측정하기 위한 새로운 척도들을 개발했다는 점에서 의의가 있다. 향후 개발된 측정모형을 기반으로 다양한 평가와 적용이 수행될 필요성이 있다. 본 연구는 모바일환경에서 주관적 삶의 질을 과학적이고 경험적으로 측정한 척도를 제공함으로써 정보화의 궁극적인 목표인 기술적 진보와 삶의 질 향상 간의 균형이 유지되도록 삶의 질 수준이나 가치를 지속적으로 파악하는데 유의미한 시사점을 주고 있다. The article defines a concept of life quality and tests a validity of measurement method in a mobile-environment. The concept of life quality is defined as a subjective quality of life, which is measured in terms of the person-environment fit. The scale of measurement consists of 8 dimensions of life quality and 38 measurement items. The assessment of construct validity is performed through the confirmatory factor analysis which utilizes AMOS 5.0. I produce the Cronbach a-reliability coefficient in order to comprehend a validity and a consistence between indexes. I use the two-way ANOVA to test differences of life quality between sex and a fulfillment of mobile user. I can summarize results as followings. First, the elements of life quality in the mobile-environment consist of sociality, leasureㆍculture, function, security, economy, health and autonomy. Second, the total fit index satisfies the assessment standard. In addition, the satisfactory group is higher in the quality of life related to the leasureㆍculture and the function than the unsatisfactory group, and men's group is higher in the quality of life related to the fulfillment and the function than women's. This article finds out new scales and constructing elements of life quality. The developed measurement model can be applied to assessments to general relations between a quality of life and a mobile environment. The thesis has an important significance in that it seeks for a balance between a technological progress of informationization and an improvement of life quality as providing the scales to measure scientifically and empirically the subjective quality of life in the moble.

This thesis analyzes the connection between internet use trend of the netizen and political participation. An analysis was made to assess the influence of the political and social tendencies of the netizen and the successful political experience trends on the political efficacy. The result of the analysis shows higher political efficacy and internet political activities for netizens with liberal and revolutionary disposition, Roh Mu Hyun voters and anticipators. This analysis result supports the hypothesis that social and political tendencies and successful political experiences of the netizens affect the political efficacy. In other words, the political use of internet indirectly influences the political participation through the parameter of the netizen's political efficacy. Accordingly, the internet use trend of the netizen influenced their voting participation during the 16th presidential election.

For the rapid endotracheal intubation, the ideal neuromuscular blocking drug with short onset time, short duration and few side effects has so far not been found. Succinylcholine is still, inspite of its side-effects and contraindications, the standard drug of choice for rapid intubation. But, high-dose vecuronium as an alternative to succinylcholine for rapid intubation may be recommended. To compare the intubating conditions with that in succinylcholine, the onset and cardiovascular effects of high-dose vecuronium(0.3 mg/kg) were evaluated clinically with a scoring system. The results are as follows ; 1) High-dose vecuronium may provide an alternative means of achieving a rapid onset of neuromuscular blockade. 2) High-dose vecuronium shows minimal effects on cardiovascular system. In concluson, high-dose vecuronium as an alternative method for rapid endotracheal intubation may be recommended without any significant cardiovascular change if succinylcholine is contraindicated.

Lycii fructus is the fruit of Lycium chinense Miller and is part of the Solanaceae family. Lycii fructus produces various effects such as hypotensive, hypoglycemic, anti-pyretic, and anti-stress activities. Lycii fructus is known to contain betaine, carotene, nicotinic acid, zeaxanthin, and cerebroside. In the present study, the effects of Lycii fructus aqueous extract on lipopolysaccharide (LPS)-induced inflammation in murine raw 264.7 macrophage cells were investigated. In this study we utilized the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcriptionpolymerase chain reaction (RT-PCR), Western blotting, and nitric oxide (NO) detection. Lycii fructus aqueous extract suppressed NO production by inhibiting the LPS-induced expressions of inducible nitric oxide synthase (iNOS) and tumor necrosis factor-alpha (TNF-$\alpha$) mRNA and iNOS protein in murine raw 264.7 macrophage cells. Also, Lycii fructus aqueous extract suppressed the activation of nuclear factor-kappa B (NF-${\kappa}B$) in the nucleus. These results demonstrated that Lycii fructus aqueous extract causes an anti-inflammatory effect that was likely produced by the suppression of iNOS expression through the down-regulation of NF-$\hat{e}B$ binding activity.

In this study, it was observed through the ability of performing secondary tasks and baseline fetal heart rate how the supply of lavender, peppermint and highly concentrated oxygen (40%) affected distraction due to the performance of secondary tasks in the driving environment. Twelve male university students conducted secondary tasks while driving in the environments (6 in total) mixed and designed with oxygen concentration (21%, 40%) and the condition of odors (Normal, Lavender, Peppermint). The test was proceeded in order of stable state (5mins), driving (5mins), and secondary tasks (1min), and by extracting ECG data from every section by 30secs, the mean value of baseline fetal heart rate was calculated. As a result of analysis, in the ability of performing secondary tasks, a percentage of correct answers showed no difference in oxygen concentration and the condition of odors (p > 0.05). In performance completion time, a percentage of correct answers decreased showing a statistically significant difference in the condition of odors compared with the condition where odors were not provided (p < 0.05). As for baseline fetal heart rate, in the comparison between sections, while performing secondary tasks, it increased showing a significant difference compared with stable state and driving state (p < 0.05). The effect of interaction was observed in oxygen concentration and the condition of odors. When odors were not provided, baseline fetal heart rate decreased in 40% oxygen concentration compared with 21% oxygen concentration (p < 0.05), however, when peppermint was provided, it increased in 40% oxygen concentration compared with 21% oxygen concentration (p < 0.05). In conclusion, the fact that the condition of odors increased the ability of calculation, and when only the highly concentrated oxygen was provided, parasympathetic nerve system was activated, however, when highly concentrated oxygen was provided with peppermint at the same time, sympathetic nervous system (sns) was activated, which had a negative effect on the autonomic nervous system was drawn.
