In fixed implant prostheses, splinted one-piece superstructures have definite advantages over segmented superstructures in terms of less marginal bone loss around the implants and long-term success rates. However, owing to jaw, the presence of discomfort in jaw opening muscles must be checked before proceeding with a one-piece superstructure. The patient in this case had all his teeth extracted and used provisional dentures for three months to evaluate the newly established vertical dimension. For fixed implant prostheses, implants were splinted together in the form of a fixed full-arch bridge in both the maxilla and the mandible. While using provisional implant restoration, the vertical dimension and occlusal plane were evaluated, and the patient was satisfied with the occlusion, function, and esthetics. For definitive prostheses, a metal framework was fabricated in one piece that lasted until now, and upon periodic patient recall, a satisfying result, in terms of function and esthetics, followed.

Purpose: To assess the effect of pars plana vitrectomy and gas tamponade on corneal endothelial cell density. Methods: The corneal endothelial cell density in 145 eyes that underwent pars plana vitrectomy was examined with a noncontact specular microscope 3 months pre- and post-operation. The subjects were divided as follows: Group 1 (32 eyes) underwent pars plana vitrectomy, group 2 (26 eyes) underwent pars plana vitrectomy combined with gas tamponade, group 3 (34 eyes) underwent pars plana vitrectomy combined with phacoemulsification and group 4 (48 eyes) underwent pars plana vitrectomy combined with phacoemulsification and gas tamponade. The changes in corneal endothelial cell density between groups was compared. Results: The mean endothelial cell loss was more significant in group 2 than in group 1 (p = 0.012), and there was no difference between groups 3 and 4 (p = 0.063). However, after excluding 6 eyes that had blood in the center of the corneal endothelium as a result of being in the prone position following gas tamponade, the mean endothelial cell loss in group 2 was not less than in group 1. In eyes with blood in the corneal endothelium, endothelial cell loss significantly increased (p < 0.001). Conclusions: The results of this study suggest that ophthalmic surgeons should attempt to carefully control bleeding and sufficiently irrigate the vitreous during pars plana vitrectomy combined with gas tamponade.

The purpose of this study was to test the mediating effects of the cognitive emotion regulation strategies in relation between social supports and psychological well-being. 200college students(105 males, 95 females) were asked to complete the social support scale, the cognitive emotion regulation strategies scale, and the psychological well-being scale. the results of this study were summarized as follows: First, social support and cognitive emotion regulation strategies affected positive influence to psychological well-being. Second, the mediating effects of adaptive cognitive emotion regulation strategies was found significant in the relation between social supports and psychological well-being. Third, the negative mediating effects of maladaptive cognitive emotion regulation strategies was found significant in the relation between social supports and psychological well-being. In this study, it was confirmed that cognitive emotion regulation strategies as mediators in relational with social support as a predictor and psychological well-being as an outcome variable. Such results imply that choosing social support and cognitive emotion regulation strategies be important for the enhancement of collage student's psychological well-being. 본 연구는 대학생의 사회적 지지와 대학생의 심리적 안녕감 관계에서 인지적 정서조절 전략이 매개역할을 하는지 규명하는데 목적이 있다. 이를 위해 대학생 200(남 105, 여 95)명을 대상으로 설문지를 통해 자료수집을 하였다. 본 연구의 결과를 살펴보면 다음과 같다. 첫째, 사회적 지지, 인지적 정서조절전략은 심리적 안녕감에 정적인 영향을 미치는 것으로 나타났다. 둘째, 부적응적 정서조절 전략은 사회적 지지와 심리적 안녕감 간의 관계를 부적으로 매개할 것이라는 가설이 지지되었다. 셋째, 적응적 정서조절 전략은 사회적 지지와 심리적 안녕감 간의 관계를 정적으로 매개할 것이라는 가설이 지지되었다. 이 연구를 통해 사회적 지지와 심리적 안녕감 간의 관계에서 인지적 정서조절전략의 매개효과가 유의함을 확인하였다. 이로써 대학생들의 심리적 안녕감을 향상시키는데 사회적 지지와 인지적 정서조절전략을 선택하는 것이 중요함을 밝혔다.

Background: Upper extremity venography is one of the methods usually used in venous mapping for furtheroptimization of the surgical strategy. With reduction in dose of contrast media and radiation, preservation of venographic image quality is valuable although a challenge in clinical applications. Purpose: We introduce a new bolus tracking venography method using a stepping-gantry technique for venous mapping before hemodialysis vascular access creation. Methods: Between January 2012 and October 2012, we analyzed the digital subtraction venography data sets of ten patients with end-stage renal disease (ESRD). Digital subtraction venography using a stepping-gantry technique represents a simple modification of the conventional stepping-gantry angiography applicable to the upper extremity. The examinations were reviewed by two radiologists in order to ascertain the opacification quality of the venographic images. We also assessed the amount of the dose of contrast media used as well as the radiation exposure dose during the venography. Results: Two radiologists examined the opacification quality, and more than 84% of the analyzed veins of the patients were graded as good regarding visualization of the cephalic vein of the forearm, the cephalic and basilic veins of the upper arm, and the subclavian vein. The average dose of contrast medium used in ten patients was 10.6 mL (range 10-12 mL), and the mean accumulated dose during the examination was 3.5 mGy (range 2-5.2 mGy). Conclusion: Preliminary findings indicates that single bolus stepping-gantry venography may be a valuable and alternative method for venous mapping prior to hemodialysis vascular access creation as it uses less contrast media and reduces the radiation dose.
