Purpose: This study was conducted to identify factors influencing endoscopy nurses' protective behavior against radiation exposure. Methods: Data were collected using self-report questionnaires from 122 endoscopy nurses in 21 hospitals located in Seoul, Gyeonggi province and six metropolitan cities in Korea. Collected data were analyzed using SPSS 18.0 program and included multiple regression analysis. Results: 1) There were significant relationships between protective behavior and protective environment (r=.74, p<.001), number of education sessions on radiation protection (r=.32, p<.001), number of protective devices (r=.28, p=.002), number of fellow nurses (r=.27, p=.003), and protective attitude (r=.18, p=.048). 2) Protective environment (${\beta}=0.79$, p<.001), type of hospital foundation (${\beta}=0.18$, p=.011) and marital status (${\beta}=-0.13$, p=.040) significantly predicted endoscopy nurses' protective behavior against radiation exposure (adjusted R square=.58, p<.001). The most powerful predictor for protective behavior against radiation exposure was a protective environment. Conclusion: Effective protective behavior of endoscopy nurses from radiation exposure requires improvement in their protective environment. Hospital administrators and managers should make efforts to increase protective facilities in endoscopy departments and provide endoscopy nurses with regular education on radiation protection.

Purpose: The purpose of this study was to investigate job stress and job satisfaction among nurses in gastrointestinal endoscopy units, and factors related to their job stress and job satisfaction. Methods: The study participants were 153 nurses working in gastrointestinal endoscopy units at eleven general hospitals. Job stress and job satisfaction were measured using nurses's job stress scale and the index of work satisfaction respectively. Results: The average job stress was 3.67 (range 1~5) and job satisfaction was 2.90 (range 1~5). Gastrointestinal endoscopy unit nurses, who were full time worker, having more than 7 years of clinical experiences, having higher incomes, having high subjective work-intensity, and having an intention to change their working units, showed greater job stresses than those of the others. There were significant differences in job satisfaction according to subjective health status, the types of employment, subjective work-intensity, subjective aptitude, intention to change working units, major nursing tasks, and the numbers of major nursing tasks. Also, the subjects's job stress showed a negative correlation with job satisfaction. Conclusion: Findings suggest that management strategies should be developed to increase job satisfaction focusing on general and job characteristics associated with job stress.

Purpose: This study aimed to identify the effects of musculoskeletal symptoms and burden on presenteeism among nurses in a gastrointestinal endoscopy unit. Methods: This was an observational cross-sectional study. Data were collected through self-reported questionnaires administered to 140 nurses working in the gastrointestinal endoscopy unit of a hospital located in Busan metropolitan city. Results: The body part with the most musculoskeletal symptoms was the back (73.2%), and the most common musculoskeletal burden work was "when you have to stand or maintain the same posture for a long time in a lead apron protection clothes." The factors most related to work impairment were working hours, musculoskeletal symptoms, and musculoskeletal burden, with an explanatory power of 63.3%. Factors affecting perceived productivity were working hours and musculoskeletal symptoms, with an explanatory power of 29.2 %. Conclusion: To reduce work impairment and increase the perceived productivity of nurses in gastrointestinal endoscopy units, various programs and improved working environments are needed that can improve musculoskeletal symptoms and reduce musculoskeletal burden.

Purpose : The aim of this study was to evaluate the latest tendency of esophageal foreign body's extraction and to obtain a consensus from recent trends of indications and techniques of flexible endoscopy of esophageal FB in children. Methods : We retrospectively reviewed medical records of 127 cases with foreign bodies in esophagus at Dept. of Pediatrics and Otorhinolaryngology, Gyeongsang National University Hospital (GNUH) from Jun, 1987 to July, 2001. They were divided into two groups by the kinds of endoscopy : flexible endoscope(66 cases) or rigid endoscope(61 cases). Rigid endoscopy was performed under general anesthesia at Dept. of Otorhinolaryngology but flexible endoscopy was performed without general anesthesia or sedative drugs(midazolam or diazepam). Results : An annual number of cases of two groups were similar from 1991 to 1998. But from 1999, flexible endoscopy was performed actively. Asymptomatic cases were frequently observed in flexible endoscopy(28 cases/66 cases) but swallowing difficulties were frequently observed in the rigid endoscopy group(25 cases/61 cases). Other symptoms were vomiting, irritability, chest discomfort and abdominal pain. The total number of cases with underlying disease(esophageal stenosis, cerebral palsy) was 8. The total number of cases with complications (erosion, ulcer, bleeding, perforation) was 11. The above cases were not correlated between the two groups. In 55 cases(83.3%) of the flexible endoscopic group and 53 cases(86.8%) of the rigid endoscopic group, foreign bodies in the esophagus were removed within 24 hours. Conclusion : We could not find any benefit in rigid endoscopic technique. Flexible endoscopic FB removal can be performed safely and effectively in children by an experienced endoscopist.

To identify relationship between the airborne concentrations of formaldehyde and the causal factors in the endoscope unit of hospitals, a total of 48 workers selected from 4 hospitals (3 university hospitals and 1 national hospital) were investigated. Airborne formaldehyde samples were collected using passive samplers and subsequently analyzed by HPLC according to the OSHA method 1007. The geometric mean(GM) of airborne formaldehyde concentrations was 0.056 ppm (range: 0.003~0.923 ppm). The rates of exceeding exposure limits of OSHA PEL-TWA and NIOSH REL-TWA were 4.2 % and 83.3%, respectively. The STEL GM concentration was 1.428 ppm(range: 0.103~14.773 ppm). Ventilation condition (p=0.001) and temperature (p=0.017) were statistically significant causal factors for the airborne exposure concentration of formaldehyde in the endoscope unit of hospitals. In conclusion, the workers in the endoscope unit of hospitals were highly exposed to formaldehyde, and adequate controls such as appropriate management of ventilation and temperature are recommended to reduce over exposure to formaldehyde.

Purpose: Recently, a wide application of gastrofiberscopy in the pediatric group have revealed that nodular duodenitis is not an uncommon disease in children and is suspected to be associated with H. pylori infection. The aim of this retrospective study was to investigate the clinical and histopathologic features in children with nodular duodenitis, and to assess the correlations beween both. Methods: During a period of 5 years (Jan. 1995~Dec. 1999), we investigated clinical, endoscopic and histopathologic features of 39 consecutive patients diagnosed as having nodular duodenitis at Pediatric department of Seoul Red Cross Hospital. In 35 children with nodular duodenitis endoscopic biopsy specimens were stained with Hematoxylin & Eosin and Giemsa's stain, and were graded according to the criteria outlined by Triadafilopoulos, Whitehead et al., and Prieto et al.. Statistical analyses were performed with Graph PAD InStat. Results: The prevalence rate of nodular duodenitis was 17.1% and the most frequent chief complaint was abdominal pain (69.2%). Endoscopically grade 1 was the most common (45.7%) and nodular gastritis was coexistent in 28.3%. The most common histology of the duodenum was grade 2 (54.3%), and the most common histologic score of the stomach was 2 (42.9%). H. pylori was found in the duodenum in 37.1%, and in the stomach in 31.4%. The correlation coefficient between the endoscopic grade and the histologic grade of nodular duodenitis was 0.3983 (p=0.0178). And the correlation coefficient between the histologic grade and the grade of H. pylori colonization in the duodenum was 0.5154 (p=0.0018). Conclusion: There was significant correlation between the endoscopic grade and the histologic grade of nodular duodenitis, and was also significant correlation between the histologic grade and the grade of H. pylori colonization in the duodenum. Therfore H. pylori infection should be regarded as an etiologic factor of nodular duodenitis.
