Background : Acquired tracheoesophageal fistula(TEF) results mostly from Prolonged tracheal intubation and insertion of nasogastric tube. Although the incidence has decreased since the usage of low pressure, high volume cuff of endotracheal tube, it is seldom cured spontaneously and needs surgical treatment. Material and Methods : We have retrospectively reviewed five cases of TEF who underwent surgical treatment for cure from March, 1990 to September, 2001 and analyzed the cause, treatment, postoperative complications and prognostic factors. Results : Majority were men(80% : 4 of 5 patients) and the mean age was 29.4 years old(range, 11-58). The most predominant etiology was prolonged intubation or tracheostomy(80% : 4 of 5 patients) and 3 of 5 patients were treated by tracheal resection and end to end anastomosis with primary closure of esophagus. Postoperative complications occurred in 4 patients the most common complications were wound infection(4 cases) and esophageal leakage(2 cases). Extubation was done on postoperative day 11.5(range, 1-33) days, and factors causing delayed extubation were status esophagus. epilepticus, edema, and tracheal stenosis. Conclusion : Spontaneous closure of TEF is seldom possible and the surgical treatment of choice is tracheal resection and end to end anastomosis with primary repair of the esophagus. preoperative pulmonary rehabilitation and early extubation postoperatively are important factors for success.

Purpose: This study was to explore factors affecting musculoskeletal symptoms of the child care centers' teachers in Korea. Methods: This study was a descriptive research, using a cross-sectional survey. Convenience samples of 230 child care centers' teachers aged 20 to 65 were selected. A self-administered questionnaire was used to measure general characteristics, job-related characteristics, exercise habit, fatigue and musculoskeletal symptoms of the body parts. The data were analyzed with the SPSS/WIN 21.0 program. Results: Shoulder pain (73.5%), low back pain (72.6%) and wrist/hand pain (57.8%) were the most common musculoskeletal symptoms. Shoulder pain significantly differed depending on the age of children in charge at the child care center (p<.047). The exercise habit was related to low back pain (p<.028) and the career was linked to wrist/hand pain (p<.046). The logistic regression analysis revealed exercise habit and fatigue were the risk factors on musculoskeletal symptoms of many body parts. Conclusion: These results suggest that interventions targeting the child care centers' teachers should be considered job-related characteristics and fatigue in order to prevent musculoskeletal disorder. Thus, there continues to be a need to develop exercise program for the child care centers' teachers.

The aim of this study was to investigate effects of odor intensity on the olfactory sensibility and sensibility structure. Three odor samples(B, C, and D) of T&T olfactometer were selected by the preference rank : the lowest preference(C) ; the moderate one(B) ; and the highest one(D). Three levels(-1, +1, and +3) of odor intensity at each sample were presented to 50 subjects(25 female, 25 male), and the olfactory sensibility was rated by using semantic differential scale composed 25 sensibility characteristics. At each sample, the olfactory sensibility was significantly affected by the odor intensity. Moreover, the structure of olfactory sensibility was influenced by the odor intensity. However, two sensibility factors such as 'aesthetics' and 'intensity' were common factors, whereas 'mildness', 'complexity', and 'activity' were unique factors with odor intensity. In conclusion, the olfactory sensibility was significantly affected by the odor intensity and the odor preference.
