The present study was performed to evaluate the effect of tetracycline-HCl on the change of implant surface microstructure according to application time. Implant with pure titanium machined surface, HA-coated surface and dual acid etched surface were utilized. Implant surface was rubbed with $50mg/m{\ell}$ tetracycline-HCL solution for ${\frac{1}{2}}$min., 1min., $1{\frac{1}{2}}$min., 2min., and $2{\frac{1}{2}}$min. respectively in the test group. Then, specimens were processed for scanning electron microscopic observation. The results of this study were as follows. 1. Both test and control group showed a few shallow grooves and ridges in pure titanium machined surface implants. There were not significant differences between two groups. 2. In HA-coated surfaces, round particles were deposited irregularly. The roughness of surfaces conditioned with tetracycline-HCL was lessened and the cracks were increased relative to the application time. 3. The etched surfaces showed the honey comb structures. The surface conditioning with tetracycline-HCI didn't influence on its micro-morphology. In conclusion, the detoxification with $50mg/m{\ell}$ tetracycline-HCI must be applied respectively with different time according to various implant surfaces.

결론적으로 거대세포바이러스 대장염은 면역기능이 유지된 사람에게서는 드문 질환으로 알려져 있으며 그에 따른 합병증으로 대장협착이 발생한 경우는 더욱 흔하지 않다. 연자들은 정상면역을 가진 성인에서 폐렴에 의한 급성 호흡곤란 증후군과 패혈증으로 중환자실 치료 중 지속적인 복부통증, 고열, 혈변으로 대장내시경을 시행하여 거대세포 바이러스 대장염을 진단하였고 이로 인한 장협착이 발생하여 장절제술까지 시행한 1예를 경험하여서 보고하였다. Cytomegalovirus (CMV) infection has been described in immunosuppressed individuals such as patients with AIDS, those receiving chemotherapy, and post-transplantation. CMV can cause severe disease either via reactivation of latent virus or via primary infection. In immunocompetent patients, CMV infection is usually transient and does not exhibit many symptoms. The colon is the site most frequently affected by severe CMV disease in immunocompetent patients. Clinically, CMV colitis commonly presents with diarrhea, fever, and abdominal pain. Although some patients recover spontaneously, others suffer from severe complications, such as bowel perforation, severe gastrointestinal bleeding and, rarely, stricture, and surgery is the choice of treatment in these patients. We report a case of stricture of the proximal transverse colon, presenting as a complication of CMV colitis, in an immunocompetent man with acute respiratory distress syndrome. We performed laparoscopic segmental resection of the proximal transverse colon. (Korean J Med 2013;84:284-289)

이 연구에서는 자전거이용 활성화에 관한 법률, 도로교통법, 자전거 이용시설의 구조·시설 기준에 관한 규칙, 도시 계획시설의 결정·구조 및 설치기준에 관한 규칙의 자전거 관련 주요 규정들의 현황과 문제점을 분석하였으며, 자전거 이용자들의 안전성과 편의성 측면에서 분석하였다. 법·제도 개선안으로 첫째, 자전거 이용자의 법적 권리보장을 위한 자전거 보험제도 의무화, 둘째, 교차로 내에서 자동차, 보행자와의 상충을 줄이기 위한 횡단보도 앞 속도방지시설 설 치 법제화, 셋째, 교차로 내 자전거 직접좌회전을 위한 자전거 전용차로 설치 방안을 제시하였다.

Purpose: The purposes of this study are (1) to examine why users commit to M-SNG and (2) to understand what factors impact M-SNG users’enjoyment, motivation and commitment. Methods: We use a questionnaire survey to collect 190 data on users’ perception on M-SNG. we also use a structural equation modeling method with Smart PLS 3.0 Results: Playfulness, design aesthetics, competition and social identity are found to be statistically significant factors affecting enjoyment and motivation. Also, enjoyment and motivation are found to be statistically significant factors affecting commitment. Conclusion: We suggest three points of view as game factors, socio-game factors, and social factors. Game factors are more important than other factors. Also, enjoyment is a more powerful factor than motivation in affecting user’s commitment to using M-SNG.

We report a case of acute kidney injury following extracorporeal shock wave lithotripsy. A 41-year-old man with diabetes mellitus had suffered from urinary difficulty after several treatments of ESWL, bilaterally. It was suspected that fragments of renal stones had caused an obstructive nephropathy with bilateral hydronephrosis. Fortunately, even without renal replacement therapy, renal function gradually returned. (Korean J Med 2012;82:628-631)
