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)

N-nitrosamines are a class of carcinogenic chemicals that can pose significant hazards to the human life. Ultraviolet (UV) light irradiation is considered as one of the effective methods to reduce N-nitrosamines in the aqueous phase. This study aimed to investigate the pH influence on UV photodegradation of N-nitrosamines (i.e., N-nitrosodibutylamine (NDBA) and N-nitrosopyrrolidine (NPYR)) closely related to water treatment. Photodegradation rate constants of NDBA and NPYR remained between 3.26×10-2 L/W-min to 5.08×10-3 L/W-min and 1.14×10-2 L/W-min to 2.80×10-3 L/W-min at pH2-10, respectively. This study also focused on the formation of oxidized products (i.e., primarily NO2- and NO3-). Under slightly acidic and eutral conditions, NO2- formation was more prevalent than NO3- formation, while under strong acidic conditions, NO3- was more prevalent. There was no significant change in total organic carbon (TOC) and total nitrogen (TN), suggesting negligible loss of N-nitrosamines and degradation products from the system. NDBA was easily photodegraded than NPYR. This study also demonstrated that a lower pH is a favorable condition for photolytic degradation of N-nitrosamines in water.

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.

데이빗 트레이시(David Tracy)의 신학적 언어로서의 유비적 상상력(analogical imagination)

노영상 국제기독교언어문화연구원 1997 기독교언어문화논집 Vol.1 No.-

Yong Sang No. 1997. Analogical Imagination As the Theological Language of David Tracy- Collected Papers on Christian Language Culture. David Tracy, a American theologian, who teaches in Chicago University, suggests analogical imagination as a theological language for this pluralistic situation. He, as a revisionist theologian, says that theology has to be built up by public discourse in order that nonchristians amy understand it. He embraces both the liberal theology emphasizing human experience and the neo-orthodox theology emphasizing divine revelation into his theology of analogical imagination. His analogical language includes similarities-in difference and radical dissimilarity-in- similarity as a dialectical phase. This analogical vision makes the conversation with others possible. He developed conversation theory from the foundation of the comtemporary hermeneutics.(Ho Nam theology seminary)

The purpose of this study was to compare shear bonding strengths and debonding patterns of the ceramic brackets attached on the crystal which were grown on the enamel surface of tooth with different concentrations of lithium sulphate-contained polyacrylic acid in different application times. Four kinds of concentrations of mixed solutions were made and applied to the enamel surface on extracted human premolars. The solutions were made by adding 0.3M or 0.6M of lithium sulfate to 50% or 65% of polyacrylic acid with 0.3M sulfuric acid. The solutions were applied for 30 or 60 seconds. After bonding, a universal testing machine was used to measure the shear bond strength, and then observations were made of debonding patterns through the stereoscope. And the enamel surface was observed through the scanning electron microscope to examine the pattern of crystal growth and debonding. 1. Shear bond strength in the enamel surface treated with 50% polyacrylic acid was higher tan that with 65% polyacrylic acid. 2. There were no statistical differences in shear bond strength according to concentration of lithium sulfate and application time of solutions. 3. Enamel surface was almost free of resin debris after debonding. 4. Enamel surface treated with 50% polyacrylic acid showed higher density of crystal growth than that with 65% polyacrylic acid under scanning electron microscope.

In general, sushi is considered as the rice hardened into a mass and put on fish. It was kind of new food developed in Edo period. First, there was Nara-zhshi which fish meat fermented in rice and only the fish meat was eaten after discarding the rice. After then, rice and fish were fermented and eaten together, which is Nama-Nara-zushi. Since rice vinegar, the landmark in sushi making, has been used, the variety of sushi has no limit. It is developed by Japanese and representative foods of Japan today. However, its origin, Nara-zhshi is found in China, Korea, and East Asia. Therefor, it is universal stored food eaten by not only Japanese, but also all Asians. Many studies have assumed that it is originated in Southeast Asia and transmitted to China and later to Korea and Japan. In the east coast of Korea facing Japan and closest area, similar types of food Sikhea is found. Also, some say that the word sushi is originated from Korean shinbap. Therefore, it is possible that sushi is transmitted from Korea to Japan.

孟子之 君子 孝

노상오 부산교육대학교 교육대학원 2003 논문집 Vol.5 No.-

맹자의 사상은 공자의 사상을 계승, 발전시킨 사상이다. 맹자의 교육의 핵심이 君子교육으로 君子는 德性을 갖추고 本能을 지니는 것을 그 내용으로, 문답하고 私淑하는 자세로 교육의 方法으로 자연스러운 즉 時雨化育者하는것을 교육의 成果로 하는 교육을 주장하였다. 孟子는 君子의 三樂 (而王天下不與存焉 父母俱存 兄弟無故-樂也 仰不愧於天 府不作於인二樂也 得天下之英材而敎育 三樂也 君子有三樂而王天下不與存焉 「盡心上」]을 지녀야 하며, 가정의 객관적 환경과 그리고 자신의 주관적 心象과 객관적인 英才에게 주관적인 敎育을 실시함으로써 樂이 된다고 맹자는 보았다. 孟子的思想繼承發展了孔子的思想. 孟子敎育思想的核心是君子敎育. 君子是以德性和本能的. 以君子爲內容, 他主張用問答和私淑的形式的敎育方法, 以自然卽'時雨化育者爲敎育的成果. 孟子認爲君子必備‘三樂’(而王天下不與存焉. 父母俱存, 兄弟無故一樂也, 仰不傀於天, 府不作於人二樂也, 得天下之英材而敎育. 三樂也. 君子有三樂而王天下不與存焉盡心上). 在孟子思想中的敎育是以家庭的客觀배境和自己的主觀心象給客觀英才敎育, 才成爲'樂' 的.
