When performing an endotracheal intubation or tracheotomy to an unconscious patient in emergent situations, one should consider the possibility of later complication of laryngo-tracheal stenosis which can result in difficulties in decannulation. Laryngo-tracheal stenosis is a bothersome problem developing as a complication of treatment by tracheotomy with a cuffed tube and long-term endotracheal intubation with assisted ventilation. One hundred twenty-three cases of laryngo-tracheal stenosis patients during the four yew period from May 1992 to April 1996 were restrospectively reviewed according to several parameters such as the duration of intubation, site of stenosis, treatment modality and, site of tracheostoma. The present report is an analysis of these materials to search for the possible etiologic factors and its proper preventive methods. It was desirable that the endotracheal intubation should be limited within 20 days at most. Tracheotomy performed by non-otolaryngologists has a tendency to be on a higher level of trachea. Technical precautions should be taken into consideration when doing a tracheotomy. The success rate of decannulation of tracheal T-tube was 78.8% and it required average 11 months.

Irradiation of food is not only used for sanitation purposes but can be used for processing techniques to reduce or eliminate toxic or undesirable compounds on food. Irradiation wag effective to reduce the allergenicity of food by modification of the structure of proteins causing allergy reactions. Volatile N-nitrosmaine was reduced or eliminated by irradiation in the model system study and the breakdown products by irradiation did not recombine under human stomach conditions (pH 2,3, and 4,37$^{\circ}C$). The possibility of residual chlorophyll b reduction by irradiation was also found, and the model study indicated that irradiation be used to destroy chlorophyll b, resulting in protection from photooxidation in oil without acceleration of lipid oxidation during irradiation. In this paper, several on-going research projects for the application of food irradiation as a new processing technique are introduced, including reduction of food allergens, breakdown of volatile N-nitrosamine and residual chlorophyll b.

Objectives : In an epidemiologic study on the health impact of Agent Orange exposure, the valid estimation of exposure level is the most important step. Based on recent studies, we examined the correlation between exposure levels categorized by personal exposure estimates and serum 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD, Dioxin), exploring the possibility of utilizing the exposure level as a surrogate for the estimate of exposure to agent orange. Methods : During the study period (Jan 1996-Feb 1996), blood specimens of 745 subjects taken randomly among 1,329 persons and kept frozen, were analyzed for 2,3,7,8-TCDO and six other dioxin congeners. The serum dioxin and congeners were measured in 1998 by CDC, adjusted for serum lipids. We categorized the total exposure scores into five groups based on Agent Orange exposure data collected by interview and military records. Pearson and Spearman's correlation coefficients & multiple regression analysis were used to identify the relationship of the exposure level categorized with serum concentration of 2,3,7,8-TCDD, and six other dioxin congeners. Results : Dioxin and the other congeners, except 1,2,4,6,7,8-HpCDD, showed significant correlations to exposure categories (p<0.005): 2,3,7,8-TCDD and OCDD showed positive correlations, whereas the other congeners did negative. The values of 2,3,7,8-TCDD differed according to exposure category and proportionally increased from the low exposure group to the high, a dose-response relationship, even after other possible confounding variables were adjusted for. In multiple regression analysis, age$(\beta=0.033)$, dioxin$(\beta=0.433)$, 1,2,3,7,8-PeCDD$(\beta=-0.998)$, 1,2,3,4,7,8-HxCDD$(\beta=-0.773)$, 1,2,3,6,7,8-HxCDD$(\beta=0.255)$, 1,2,3,7,8,9-HxCDD$(\beta=-3.468)$, 1,2,3,4,6,7,8-HpCDD$(\beta=0.109)$ we re found to be significantly related to the total exposure score(p<0.005). Conclusion : This study demonstrated that the use of such categorizations as a surrogate measure of agent orange exposure in identifying exposure degrees in a health impact study is valid.

본 연구는 청소년 일탈에 대해 유교가 지니고 있는 도덕과 윤리에 근거하여 예방적 차원은 어떠한지 검토한 것이다. 청소년 일탈의 문제는 쉽게 해결할 수 있는 것이 아니다. 일탈은 언제나 존재하고 있기 때문에 그것을 최소화하고 예방할 수 있는 방식을 고려하는 것이 중요하다. 한국 전통 사회에서 유교는 청소년에게 도덕적 교화와 계몽을 강조함으로서 예방 차원의 교육을 중시한다. 그 기본 전제는 청소년의 특성을 회복하는 일이 되어야 한다. 훌륭한 프로그램도 필요하고 다양한 관심도 좋지만 유교적 의미에서 볼 때, 동몽에 대한 이해와 인식이 급선무이고, 절문(節文) 교육을 현대적 차원에서 고려할 수 있어야 한다. 특히 청소년들에게 인간의 보편적 도리가 무엇인지, 어떤 덕을 지녀야 하는지, 그에 대한 자기 깨달음을 줄 수 있는 현대 도덕의 기준이 요청된다. 그것은 민주주의적 행동양식과 시민사회의 공공질서, 사람과 사람 사이의 건전한 관계망을 고려해야 한다. 다시 말하면 청소년의 올바른 길(道)을 제시해야 하고, 청소년이 체득해야 할 덕목(德)을 확인해야 한다. 청소년 일탈은 그런 가운데 새로운 삶의 세계를 경험하면서, 일탈로부터 도피(逃避)하거나 예방적 차원을 고민할 수 있다. 이에 본고는 현재 한국 청소년들에게 나타나는 일탈의 이미지와 유형, 대응의 방식을 살펴봄으로써, 문제 상황의 수준을 이해하였다. 그리고 유교적 가치에 기초한 전통 사회에서 청소년은 어떻게 인식되었는지, 그들에게 적용했던 도덕규범과 교육의 과정을 분석하였다. 특히 『중용』에 드러나는 유교의 도덕 개념을 통해, 청소년 일탈을 예방할 수 있는 도덕교육의 가능성을 모색하였다. 이는 청소년 일탈과 연관해 볼 때, 유교가 지닌 도덕과 윤리가 일탈을 예방하거나 윤리교육의 지평을 고민할 수 있도록 도와준다.

Objectives: Abdominal obesity increases mortality and morbidity from cardiovascular disease and there is a possibility that smoking effects obesity. However, previous studies concerning the effects of smoking on obesity are inconsistent. The objective of this study was to examine whether smoking is positively related to abdominal obesity in men with type 2 diabetes. Methods: Subjects consisted of 2197 type 2 diabetic patients who visited Huh's Diabetes Center from 2003 to 2009. Indices of abdominal obesity were defined as visceral fat thickness (VFT) measured by ultrasonography and waist circumference (WC). Overall obesity was defined as body mass index (BMI). Results: Statistically significant differences in WC and VFT by smoking status were identified. However, there was no statistical difference in BMI according to smoking status. Means of WC and VFT were not significantly higher in heavy smokers and lower in mild smokers. Compared to nonsmokers, the BMI confounder adjusted odds ratio and 95% confidence interval for VFT in ex-smokers and current-smokers were 1.70 (1.21 to 2.39) and 1.86 (1.27 to 2.73), respectively. Conclusions: Smoking status was positively associated with abdominal obesity in type 2 diabetic patients.
