저자들은 기종성 신우신염이 복강 및 후복강을 통해 종격동과 흉막까지 광범위하게 퍼진 사례를 체험하였기에 이를 보고하는 바이다. Emphysematous pyelonephritis (EPN) is a necrotizing infection characterized by the accumulation of gas in the renal parenchyma and surrounding tissues. Although there have been a few cases of EPN accompanied by either pneumoperitoneum or pneumomediastinum

Purpose: In IgA nephropathy (IgAN), crescent formation appears to represent a nonspecific response to severe injury to the glomerular capillary wall. This study was performed to evaluate the clinicopathological manifestations of the crescents and their effects on the clinical courses of IgAN. Methods: The patients diagnosed IgAN were included and the information about their renal biopsies, chemistries and immunohistochemistry findings were collected retrospectively. Some patients that have similar renal function and protenuria were followed up for 12 months to examine the effects of crescents on the renal prognosis. Results: 38 patients with crescents and 177 patients without crescents were enrolled. The patients with IgAN with crescents showed significantly lower renal function (MDRD eGFR 58.5 vs 88.4 ml/min/1.73 m2), higher blood pressure, larger amount of proteinuria and more severe hematuria than those patients without crescents. In pathologic findings, HS Lee grades were higher (2.9 vs 1.9). When we selected patients with mildly decreased renal function (serum creatinine <2.5 mg/dL, PCR 0.5-8 g/gCr), the patients with crescents presented lower renal function and higher proteinuria but no statistical significance. After 12 months of treatment, the patients with crescents showed significantly lower renal function (MDRD eGFR 78.6 vs 96.5 ml/min/1.73m2) and higher proteinuria (0.9 vs 0.6 g/gCr). Conclusion: The patients with IgAN with crescents showed more deteriorated clinicopathological findings than those without crescents. Despite aggressive treatments, they presented a significantly decreased renal function and larger amount of proteinuria after 1 year. So crescents are supposed to have poor effects on the clinical course.

This study analyzed and investigated of positivism to set up a hypothesis with a model of study based on a theoretical consideration to analyze a structural empowerment, a psychological empowerment, an immersion of duty, and a devotion of organization. which made the dental hygienists an object of study of investigation and analyzation in order to understand relation to elements that have an effect on a business result, effect and degree in a dental hygienist`s organization. The results of positive analysis in the study are as follows. A psychological empowerment is influenced by a level of satisfaction for their duty, educational level, and types of main duty. A structural empowerment is influenced by a level of satisfaction for their duty, total years of work, a level of salary, type of work place. Organizational devotion is influenced by the structural empowerment, total year of work, type of workplace, and a level of satisfaction for their duty. Devotion for their duty is influenced by the psychological empowerment, total year of work, type of main duty, main duty that they want in the future, and specialization for amin duty.

The purpose of the study is exploring the relationship among patient perceived quality of dental care, satisfaction, and royalty in dental clinics and hospitals. The observation of the study is outpatient visiting dental clinics and hospitals located in Seoul and Kyung-Gi Do area, and surveyed the outpatients. The contents of the survey are consisted with questions including quality of care perceived by the patients, costumer satisfaction, and royalty, and measurement for each question is using five point Likert scale. According to result of bi-variate analysis, there was the significant relationship among specialized care, value of the care, and kindness in quality of dental services, level of care in dentists significantly influenced on costumer satisfaction and costumer royalty, and there was the significant relationship between costumer satisfaction and royalty. According to result of regression analysis on the costumer satisfaction, the costumer satisfaction positively related with the convenience of facility, specialized care, value of care, patient age, number of visit, and spend time for treatment, and housewives and self-employees were likely to satisfy on care than regular employees. By result of full regression model and reduced model on costumer royalty, satisfaction could explain 86% on the costumer royalty such as re-visit and promoting other people, and increase of explain power is not significant when other independent variables joined model (full model). Considering efficiency of model, costumer royalty could be explained by satisfaction only rather than other independent variables used. Finally, This study shows that the social-demographic variables of patient influenced the patient satisfaction, and the patient satisfaction influenced patient royalty directly.

This paper presents FPGA implementation for real time face detection. Face detection algorithm is based on the skin-color filtering and region growing. The algorithm is implemented in the DIS application board with Altera cyclone Ⅱ, which is manufactured by Eyenix Co.. The experimental results show that the proposed system works efficiently.
