연구배경: 패혈증에서 Nitric oxide 스테로이드 호르몬은 혈역학적 변화와 염증반응에 관여하는데 이 두 인자는 서로 상관성이 있는 것으로 알려지고 있다. 하지만 실제 환자에서 서로의 상관성이나 임상적 의의는 연구가 부족한 실정이다. 방법: 패혈증 환자 26예와 대조군 14예를 대상으로 혈중 총 NO와 혈중 코티졸 농도를 측정하였고 이어서 제 3, 5, 7병일에도 연속적으로 측정을 하였다. 결과: 패혈증 환자군에서 초기 혈중 코티졸 및 총 NO 농도는 대조군에 비하여 유의하게 증가하였고 경증 패혈증에 비하여 중증 패혈증 환자군에서 유의하게 높았다. 초기 혈중 총 NO의 농도는 APACHE II 점수, 정맥혈 lactate 농도와 상관성이 있었다. 패혈증의 시간의 경과에 따라 혈중 NO 농도는 제 1병일, 제 5병일, 제 7병일에 혈중 코티졸의 농도와 유의한 상관성이 있었다. 결론: 패혈증 환자들에서 혈중 NO와 코티졸 농도는 증가되어 있었으며, 경과에 따라 서로 유의한 상관성이 지속되었다. 상호작용기전에 대하여는 추가적인 연구가 필요할 것이다. Background: The nitric oxide (NO) released by inducible NO synthase (iNOS) plays an important role in the pathophysiology of sepsis. Corticosteroids also play a role in the hemodynamic and inflammatory reactions in sepsis. Both have been shown to have a relationship theoretically, but their correlation and clinical impacts have rarely been evaluated. Methods: 26 patients with sepsis and 14 healthy controls were enrolled in this study. The initial random plasma total NO and the serum cortisol levels were measured. The same measurements were serially carried out on the 3rd, 5th, and 7th days. Results: The initial total plasma levels of NO and cortisol were higher in the patients with sepsis than in the healthy controls. The total NO levels were higher in patients with severe sepsis than in the those with mild sepsis. There was a correlation between the total NO and cortisol level throughout the study. Conclusion: In patients with sepsis, the levels of plasma NO and cortisol were well correlated during the first week of sepsis, which suggests an interrelationship. However, the clinical and pathogenetic implications await further evaluation. (Tuberc Respir Dis 2007; 62: 308-313)

Fresnoite 결정화 유리는 최근 비선형 광학특성으로 인하여 널리 연구되어 지고 있다. 그러나, 이전 연구 결과를 통하여 투명결정화 유리의 화학 조성으로는 정량적으로 Fresnoite 구조에 유사한 조성을 조절하는 것에 한계가 있음을 확인 할 수 있다. 본 연구에서는 $K_2O-TiO_2-SiO_2$ glass의 제조한 후, 제조된 유리를 $Sr(NO_3)_2$ 용융염에 담지하여 모유리의 표면에 Fresnoite 결정을 형성시키는 방법으로 투명결정화 유리를 제조하고, 이 때 Sr 이온이 비선형광학효과에 미치는 영향을 살펴보았다. XRD를 통하여 담지 시간에 따른 결정상 변화와 열처리를 통한 결정상 변화를 관찰하였으며, FE-SEM을 사용하여 생성된 결정의 미세구조와 Nd : YAG laser를 사용하여 2차비선형특성의 유무를 관찰하였다. A fresnoite glass-ceramics has been investigating considerably because of the second order nonlinearity as well as its permanent optical nonlinearity. However, the chemical compositions of transparent glass-ceramics examined in the previous studies have been limited to adjust the composition close to fresnoite stoichiometrically. In this study, to investigate the effect of strontium ions in glass-ceramics on second order nonlinearity, $K_2O-TiO_2-SiO_2$ (KTS) glasses soaked in molten $Sr(NO_3)_2$ were prepared. Crystalline phases of the soaked glasses were measured by X-ray diffraction (XRD) as soaking times and additional heat treatment. The exchange of strontium ions into the glass was verified by Field Emission Scanning Electron Microscope (FE-SEM). And the phenomena of second order harmonic generation (SHG) was observed using Nd-YAG laser.

비용ㆍ편익 분석을 중심으로 한 중수도 시설의 처리방법별 적정규모선정

노상환,민동기,송영일,박태욱,박주양 한양대학교 환경공학연구소 2000 環境科學論文集 Vol.21 No.-

미래의 안정적인 수자원 확보를 위한 수요관리방안인 중수도 시설 설치 시 발생하는 비용과 편익의 현재가치를 이용하여 처리방식별로 중수도 시설의 경제성 분석을 하였다. 사회적 편익을 고려하였을 경우 중수도 시설규모가 300㎥이상의 1일 처리용량의 경우 경제성이 있는 것으로 나타났다. 그러나 사적편익을 고려하였을 경우에는 사회적 편익에서 고려된 환경비용절감등의 여러 외부 편익이 포함되지 않아 중수도 시설에 의한 편익이 작아지게 된다. 따라서 사적편익만을 고려할 경우에는 대체로 경제성이 있는 중수도 시설의 규모는 사회적 비용을 고려하였을 경우 보다 커진다. Water reuse is a control method of water demand to steadily assure water resources in the future. Economical efficiency of wastewater reuse plants with various treatment processes was studied using the present value of cost-benefit. When social benefits are considered, the capacity of 300㎥/ day was found to be economically effiecient. However, when private benefits are considered, the social benefit of wastewater treatment plant decreases because the private benefits do not include environmental expenses and other benefits which are included in social benefits. Therefore, when the private benefits are only considered, the economically efficient capacity of the wastewater reuse plant will be higher than that considering social expenses.
