Background: Interest in medical malpractice claims and accidents is a day to day social issue to general public as well as medical personnel. Related laws and regulations already have been established, and institutions based on the laws and regulations also have been founded. However, in our dental community, interest and response to the issue seem insufficient. Methods: We searched four medical literature databases that are mainly cited in the medical community. Keywords including ‘dental malpractice claims’, ‘patient safety’ and ‘medical accident’ were used for the search. Among the selected literatures, we chose specific ones separately whose content is authentic and easily approachable. Results: Medical malpractice claims and accidents tend to increase around the world. As the cost or the difficulty level of surgery increases, the dispute rate also increases, which appears even more apparent in developed countries. Preventive measures to prevent the disputes and accidents are not significantly different. Three critical of them include relationship of doctor with patient, the informed consent and medical record. Conclusion: Tools for accident occurrence or communication improvement have been introduced. All of those cost time and money. However, education or professional request of liability insurance companies, self education and provision of guidelines can be immediately implemented. To implement those, dentists’ promotion at the regional or national level is imperative. rhBMP 2 is widely used at sinus augmentation, alveolar bone defect, and socket preservation.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal disorder of the hematopoietic stem cells characterized by chronic intravascular hemolysis, venous thrombosis, deficient hematopoiesis. Kidney involvement is usually benign and secondary to chronic deposition of hemosiderin. However, acute kidney injury may rarely occur in association with a hemolytic crisis or thrombotic complication. Hemolytic crisis is precipitated by nonspecific factors, such as infection, surgery and transfusion. A 35-year-old woman, who developed hemolytic crisis and acute kidney injury was admitted to our hospital presenting with acute gastroenteritis. After being treated by hemodialysis and oral low dose steroid, she was discharged with recovered renal function. Renal biopsy demonstrated acute tubular necrosis with considerable hemosiderin deposition without evidence of vascular thrombosis. A review of Korean cases showed that most of the cases featured severe renal dysfunction to such an extent to require a hemodialysis although there were no definite etiologies other than the deposition of blood iron due to massive hemolysis unlike the foreign cases. It also showed that the disease duration was longer. It can therefore be inferred that the early diagnosis and active treatment will be mandatory for the treatment of Korean patients with PNH. We reported a case of PNH with acute kidney injury and hemolytic crisis and documented by renal biopsy with review of Korean literature.

수용액에서 수용성 염료를 소수성 염료로 전환시킨 후 마이크로 버블을 이용한 침전 및 부상응집에 의한 염료를 제거하는 연구를 수행하였다. 양이온성 염료에 음이온 collector를 반응시키며, 또한 음이온성 염료에 양이온 collector를 첨가하여 소수성으로 변환시켰다. 소수성으로 전환된 염료 용액을 회분식 반응기에 저장하여 마이크로 버블을 분사시켜 색을 제거하였다. 염료 용액을 제조하기 위해 Basic Yellow 1 및 Direct Orange 10을 사용하였으며, sodium dodecyl sulfate, oleic acid sodium salt 및 amine류와 같은 음이온 및 양이온 collector를 사용하면 색 제거에 효과적이었으며, 모든 색은 8분 이내에 제거되었다. 색 제거는 collector의 첨가량과 수용액 pH의 영향을 받으며, 염료농도에 비해 극히 소량의 계면활성제를 첨가하였을 경우에는 pH에 의존하였으나, 염료농도와 비슷한 collector 양을 첨가하였을 경우에는 pH에 의존하지 않았음을 알 수 있었다. 그 이유는 collector와 염료가 1:1M로 반응하여 소수성이 완전히 부여되어야 제거됨을 알 수 있었다. The purpose of this study is to convert hydrophobic dyestuff to hydrophilic dyestuff by reacting cationic collector with anionic dyestuff and reaction anionic collector with cationic dyestuff. The removal of colors from aqueous solutions and/or dispersions has been studied by dispersed-air flotation in a batch column. In this studies used generated micro bubble by ceramic gas diffuser having micro pore size for air flotation process. In this study, a ceramic gas diffuser with micro pore size was used to generate micro bubbles for the air flotation process. Two colours were used for the experiments: Basic Yellow 1 (cationic dyestuff) and Direct Orange 10 (anionic dyestuff). All two were effectively removed by flotation within 8 mins. Sodium dodecyl sulfate, sodium oleate (an anionic collector), and amines (a cationic collector) were found to be effective as collectors in the removal of color, which was found to be related to the pH of the solution and the amount of collector added to it, with high collector dosages causing the process to become pH-independent.

Objectives: This study was performed to investigate the associations between the metabolic syndrome (MetS) and inflammatory markers. Methods: This cross-sectional analysis was performed using data from 1578 Koreans aged 40-69 years residing in a rural area. We investigated associations between MetS and circulating high sensitivity C-reactive protein (hs-CRP), white blood cells (WBC) and adiponectin. MetS was defined using the criteria proposed by the National Cholesterol Education Program Adult Treatment Panel III (ATP-III). Results: Increased WBC counts and hs-CRP levels and decreased adiponectin levels were observed in subjects with MetS. WBC, hs-CRP and adiponectin levels linearly deteriorated with an increase in the number of MetS components (all ptrend <0.005). Finally, adjusted odds ratios (ORs) for the risk of MetS by increase/decrease in 3 inflammatory markers were calculated by multivariate logistic regression analyses. In terms of changes in inflammation markers, in men, the adjusted ORs (95% confidence interval) were 1.15 (1.01-1.31) for WBC, 1.64 (1.02-2.64) for hs-CRP, and 0.19(0.08-0.45) for adiponectin, whereas corresponding adjusted ORs (95% Cls) in women were 1.27 (1.15-1.40), 0.98 (0.67-1.42), 0.09 (0.04-0.18), respectively. Conclusions: Serum adiponectin levels and WBC counts were found to be strongly associated with MetS in both sexes. However, hs-CRP lost its significance after adjusting for BMI and other inflammatory markers in women. This study shows that inflammatory response is associated with MetS in the Korean population. Further prospective studies are necessary to confirm the contribution made by inflammatory markers to the development of MetS.

This study was purpose to investigate effect of after maximal exercise on cardiorepiratory function and vascular compliance with wheelchair basketball athletes and normal athletes and sedentary. The subjects consisted of spinal cord injured(N=10), basketball athletes(N=10), controls(N=10) that used arm ergometer 30W(watt) loading after warm-up from 0W to all out per 15W. The groups analyzed systolic and diastolic blood pressure, measured on K4b2 through Monark cycle ergometer, vascular compliance through pulse wave velocity. The results were as follows : 1. Cardiorespiratory increased significantly in basketball athletes than spinal cord injured and controls. 2. Vascular compliance was increased in basketball athletes but not significantly. The results suggest that wheelchair athletes was enhanced on cardiorespiratory through basketball. Thus, wheelchair basketball was thought on effected exercise that increased blood volume, pressure, and affirmative effect in sympathetic system.
