For the success of complete denture, three essential requirements such as retention, stability and support are needed. Moreover, due to the absorption of residual ridge and scarring due to the surgery, when making a complete denture, which is difficult to form the mandibular lingual margins, various considerations such as the arrangement of the Non-anatomical dl non-anatomical teeth, the polished surface impression, the internally weighted metal framework and the use of the denture adhesive cream are necessary. In this case report, the patient has a severely resorbed edentulous ridge from severe periodontitis and has some soft tissue problems after the glossectomy due to tongue cancer. To obtain additional retention and stability, some trials such as polished surface impression taking, internally weighted metal insertion and minimal pressure impression were done for the better result. Moreover To make a metal framework that precisely shapes the desired three-dimensional shape and reduces the complicated process, minimal pressure impression method and direct metal laser sintering technique were used. 성공적인 총의치를 위해서는 유지, 안정, 지지 세가지 요소가 필수적으로 요구된다. 또한 심한 치조제의 흡수나 수술에 의한 반흔으로 인해 하악 설측변연 형성이 어려운 총의치 제작시에는 무교두 치아배열, 연마면 인상, 무게 보강 내부금속 삽입, 의치 접착 크림의 사용 등의 다양한 고려사항이 필요하다. 본 환자의 경우 심한 치주염으로 심하게 골흡수가 된 무치악 치조제를 가졌고, 또한 설암으로 인한 설절제술로 인해 연조직의 문제를 가진 환자이다. 부가적인 유지와 안정을 얻기 위해 연마면 인상과 내부 보강 금속구조물의 삽입 그리고 최소 가압 인상 등의 방법을 적용하여 보다 나은 임상적 결과를 나타내었다. 또한 원하는 3차원적 형태를 정확하게 부여하고 제작시 복잡한 기공과정을 줄인 금속 구조물을 제작하기 위해 최소 가압 인상 채득과 Direct metal laser sintering이 사용되었다.

물리 화학적 원리에 의한 환경오염 정화방법은 종종 낮은 효율을 보이면서 공사비 부담은 큰 것으로 나타나고 있다. 그러나 생물학적 방법들은 이러한 단점들을 극복하면서 토양과 지하수를 정화할 수 있는 대안으로서 그 가능성을 입증하고 있는 실정이다. 그 중에서 생물학적 통풍법은 유류오염지역에 적용하고 있으며 그 원리는 지중 오염지역에 충분한 산소를 공급함으로서 오염성분이 토착 미생물에 의해 제거되도록 하는 것이다. 본 발표는 유류오염 지역에 적용된 생물학적 통풍법의 효율을 평가하여 제시하였다.

Although diverse electronic control systems for vehicle safety issues have been developed, we still have many problems in the vehicle stability and the braking performance due to tire characteristics. Therefore, precise tire modeling and accurate tire investigation have been significant for advanced vehicle dynamic analysis. In this paper, braking distance analysis for conventional brake systems(CBS) and anti-lock brake systems(ABS) has been carried out, which contains the multi-body vehicle dynamic model and the brake control logic model. Also, tire parameters such as tread pattern design and tire/road friction, and vehicle parameters such as brake pad material and disc/pad friction have been analyzed by both computer simulation and vehicle test.

Background : High degree of awareness and performance for nosocomial infection control are very significant prevention factor of nosocomial infection which is increasing alarmingly in recent years and one of the common cause of opportunistic infection. The aim of this study was to find out the relation between degree of nurse's awareness and performance for nosocomial infection control and their psychological empowerment as a measurement tool for feeling of achievement in their hospitals. Method : We conducted a questionnaire survey during the period from August 2006 to April 2007. Investigation subjects were 262 nurses in 4 medical centers which is located in Busan. We measured nurse's awareness, performance for nosocomial infection control and psychological empowerment with questionnaire. Data analysis was performed with descriptive analysis, t-test, ANOVA and multiple regression analysis using SPSS Win(ver 12.0k) program. Result : The mean score of nurse's awareness, performance for nosocomial infection control and psychological empowerment were 4.76 ± 0.36, 4.32 ± 0.47 and 3.54 ± 0.58, respectively. The mean scores of nurse's awareness were lower than nurse's performance in total score and all subcategories. The correlation of nurse's awareness, performance for nosocomial infection control and psychological empowerment were statistically significant. The nurse's performance of nosocomial infection control was important influential factor of their psychological empowerment. Conclusion : From the result, we can concluded that nurse's awareness level was lower than nurse's performance level and nurse's performance of nosocomial infection control was important influential factor of their psychological empowerment. Therefore, methods for improving nurse's performance level are required for effective prevention of nosocomial infection and increase their psychological empowerment level.
