Purpose: To design and develop a World Wide Web-based education program that will allow trainees to interactively learn and improve the diagnostic capability of detecting pulmonary nodules on chest radiographs. Materials and Methods: Chest radiographs with known diagnosis were retrieved and selected from our institutional clinical archives. A database was constructed by sorting radiographs into three groups: normal, nodule, and false positive (i.e., nodule-like focal opacity). Each nodule was assigned with the degree of detectability: easy, intermediate, difficult, and likely missed. Nodules were characterized by their morphology (well-defined, ill-defined, irregular, faint) and by other associated pathologies or potentially obscuring structures. The Web site was organized into four sections: study, test, record and information. Results: The Web site allowed a user interactively to undergo the training section appropriate to the user's diagnostic capability. The training was enhanced by means of clinical and other pertinent radiological findings included in the database. The outcome of the training was tested with clinical test radiographs that presented nodules or false positives with varying diagnostic difficulties. Conclusion: A Word Wide Web-based education program is a promising technique that would allow trainees to interactively learn and improve the diagnostic capability of detecting and characterizing pulmonary nodules. 목적: 단순흉부촬영 상에서의 폐 결절 진단 능력을 향상시키도록 웹을 이용한 교육용 콘텐츠를 개발하고, 웹사이트를 디자인, 구축하고자 하였다. 대상과 방법: 증례는 팩스를 이용하여 수집하였다. 데이터베이스는 정상, 결절, 위양성(결절 유사음영)으로 대분류 하였다. 결절은 난이도에 따라 평이, 보통, 난해, 위음성의 4군으로 분류하였고, 방사선학적 소견에 따라 경계가 분명한 결절, 경계가 불분명한 결절, 희미한 음영, 다른 질환과 동반된 결절, 정상 구조물과 중첩된 결절로 분류하였다. 내용은 Study section, Test section, Record section, Information등으로 구성하였다. 결과: Study section은 학습형태이며 section I은 결절의 난이도에 따라, section II는 결절의 방사선학적 소견에 따라 학습할 수 있게 하였다. Test section은 난이도에 따라 level I-III까지 3가지 수준으로 하여 참여자가 난이도를 선택하여 결절 진단 능력을 알아볼 수 있도록 하였다. 대화형으로 구성하여 결과를 즉시 확인할 수 있으며 본인의 학습 효과를 알 수 있도록 프로그래밍하였다. 결론: 인터넷을 이용한 폐결절 진단을 위한 교육 프로그램은 새롭고 효과적인 교육도구가 될것이며, 본 연구를 통하여 축적된 기술과 경험을 바탕으로 방사선과학의 다른 분야 및 다양한 분야의 의학 교육 프로그램의 개발에 이용될 수 있을 것이다.

Purpose: To report the results of treatment isolated iliac arterial aneurysms by interventional procedures. Materials and Methods: Over a period of 5 years, 7 isolated iliac artery aneurysms (4 in the common iliac artery, 3 in the internal iliac artery) in 7 patients (3 women, 4 men; mean age, 65.7 years) were treated using interventional procedures. The mean aneurysm size was 35 mm (range, 30-45 mm). The common iliac aneurysms were treated using a unilateral stent graft (2 balloon expandable, 2 self-expandable) with coil embolization of the internal iliac artery (n = 3), except for 1 aneurysm that ruptured. Coil embolization alone was performed for aneurysms involving only the internal iliac artery (n = 3). Results: All patients were treated successfully, except for 1 with an initial remnant of type 2 endoleak. There were no perioperative complications. No leakage or complication occurred at the mean follow-up of 14 months (range 2-29 months). One patient with a ruptured aneurysm died of multi-organ failure during the follow-up period. Three aneurysms had decreased in size on follow-up CT. Conclusion: Interventional procedures with stent grafting and coil embolization are safe and effective treatments for isolated iliac artery aneurysms. 목적: 장골동맥에 국한된 동맥류를 인터벤션 시술로 치료한 결과에 대하여 보고하고자 한다. 대상과 방법: 지난 5년간 7명의 환자(여자 3, 남자 4; 평균 65.7세)에서 장골동맥을 단독으로 침범한 7예의 장골동맥류를 인터벤션 시술로 치료하였다. 동맥류의 평균 크기는 35 mm(30~45 mm)였다. 4예의 총장골동맥류는 스텐트 그라프트(풍선확장형 2예, 자가확장형 2예)를 동측에 설치하였고 동맥류 파열로 내원한 1명을 제외한 3예에서 내장골동맥의 코일폐색술을 병행하였다. 내장골동맥에만 국한된 동맥류 3예에서는 코일폐색술만으로 치료하였다. 결과: 모든 환자에서 시술은 성공적이었으나 1명에서 2형 endoleak가 남아있었다. 시술과 관련된 합병증은 없었으며 평균 14개월(2~29개월)의 추적기간 중에도 endoleak나 합병증은 발생하지 않았다. 동맥류 파열로 내원한 1명은 추적기간 중 다기관 기능부전으로 사망하였다. 추적 CT에서 3예의 동맥류의 크기가 감소되었다. 결론: 장골동맥에 국한된 동맥류에 대하여 스텐트 그라프트와 코일색전술을 이용한 인터벤션 시술은 안전하고 효과적인 치료법이다.

Objective: Kidneys are organs having a biological clock, and it is well known that the disruption of the circadian rhythm increases the risk of chronic kidney disease (CKD), including the decline of renal and proteinuria. Because shift work causes circadian disruption, it can directly or indirectly affect the incidence of chronic kidney disease. Therefore, the purpose of this study was to investigate the association between shift work and chronic kidney disease using a Korean representative survey dataset. Methods: This study was comprised of 3504 manual labor workers over 20 years of age from data from the fifth and sixth Korea National Health and Nutrition Examination Survey (2011–2014). The work schedules were classified into two types: day work and shift work. The estimated glomerular filtration rate, which is the ideal marker of renal function, was estimated according to the Chronic Kidney Disease Epidemiology Collaboration creatinine equation, and chronic kidney disease was defined as urinary albumin to a creatinine ratio equal to or high than 30 mg/g and/ or estimated glomerular filtration rate lower than 60 mL/min/1.73m2. The cross-tabulation analysis and multivariate logistic regression analysis were performed to confirm the association between shift work and chronic kidney disease stratified by gender. Results: The risk of CKD showed a significant increase (odds ratio = 2.04, 95% confidence interval = 1.22, 3.41) in the female worker group. The same results were obtained after all confounding variables were adjusted (odds ratio = 2. 34, 95% confidence interval = 1.35, 4.07). However, the results of the male worker group were not significant. Conclusions: In this study using nationally representative surveys, we found that the risk of CKD was higher female workers and shift work. Future prospective cohort studies will be needed to clarify the causal relationship between shift work and CKD.

여행사 e-서비스품질이 고객만족과 재구매의도에 미치는 영향

This study aims to examine the effect of the e-service quality of travel agency on the customer satisfaction and repurchase intention. To achieve the purpose, the questionnaires, total 350, were distributed for about 2 months to users who have experienced visiting website of travel agency and purchasing the travel product, but finally 234 valid samples were analyzed by SPSS for Window Ver.17.0. The following results were obtained. First, the four factors, `efficiency`, `fulfillment`, `system availability` and `privacy`, were drawn by factor analysis for the e-service quality of travel agency scale. Except the `fulfillment`, other factors effected on customer satisfaction. Second, the customer satisfaction with using website of travel agency effected in repurchase intention. It means that travel agency is able to put the e-service to attract the patronage effectively. Third, only two factors in e-service quality, `efficiency` and `system availability`, effected on repurchase intention. Directions for further research on e-service quality of travel agency are offered. Managerial implications stemming from the empirical findings about this study are also discussed.

e-Service quality is gradually more important in this I.T. generation. The most of people are using the internet for searching information and buying products. Especially, the number of customers buying products on the internet is growing up. Statistics Korea(2007) said traveling service transactions are the briskest on online. This means that travel agencies can attract many customers to them using web site if they are using it usefully. However, we lack an understanding of e-service of travel agency. Therefore, we need to understand e-service quality of travel agency well, providing via web site, to improve the customer`s satisfaction and repurchase intention. Moreover, we have to consider e-service recovery quality to cope with a service failure and prevent from losing customers. So, this study aims to examine the mediating effect of customer satisfaction on the relation between e-service quality and repurchase intention and the moderating effect of e-service recovery quality on the relation between e-service quality and customer satisfaction for better understanding e-service quality of travel agency. To achieve these objectives, the questionaries, total 650, were distributed for about 3 months, but finally 131 valid samples for this study were analyzed by SPSS Ver.17. This study found the mediating effect of customer satisfaction and moderating effect of e-service recovery quality on the relations proposed in this study. Directions for further research and managerial implications stemming from the empirical findings about this study are discussed.
