We experienced a case of acute pyelonephritis which progressed to Escherichia coli bacteremia and later complicated by empyema in a 65-year-old female. She was successfully treated with intravenous antibiotic therapy and percutaneous drainage of empyema.

Objective: The purpose of this study was to compare preceptors and new graduate nurses on their perception of preceptor teaching effectiveness. Methods: The participants were 90 new nurses and 90 preceptors who worked in A medical center. The data were collected from July 1 to September 30, 2008. A cross-sectional descriptive survey was done using a structured questionnaire. Results: New nurses' perception (4.07±.44) of the preceptor teaching effectiveness was significantly higher than perception of the preceptors (3.57±.37). Fifty five percent of new graduate nurses reported a lack of coherence in the preceptor's practice guidelines. For 5 causal factors classified on the teaching effectiveness, the factor of 'Professional knowledge and ability' showed the highest score, but 'Interpersonal and communication skill' got lowest score for both group. Preceptors responded that they did not have enough time to teach well because of their heavy workloads. Conclusions: These results suggest that the preceptors need appropriate compensation and education opportunities, and new graduate nurses need consistent education by the teaching professionals. Therefore, it is important to give preceptors full charge of the preceptorship. Also, it will be necessary to develop education programs to enhance interpersonal and communication skill for preceptors and new nurses.

Purpose: The change of the marginal bone around dental implants have significance not only for the functional maintenance but also for the esthetic success of the implant. The purpose of this study was to investigate the load transfer of internal conical joint type implant according to marginal bone resorption by using the three-dimensional finite element analysis model. Materials and methods: The internal conical joint type system was selected as an experimental model. Finite element models of bone/implant/prosthesis complex were constructed. A load of 300 N was applied vertically beside 3 mm of implant axis. Results: The pattern of stress distribution according to marginal bone resorption was similar. The maximum equivalent stress of implant was increase according to marginal bone resorption and the largest maximum equivalent stress was shown at model of 1 mm marginal bone resorption. Although marginal bone loss more than 1mm was occurred increasing of stress, the width of the stress increase was decreasing. Conclusion: According to these results, the exposure of thin neck portion of internal conical joint type implant is most important factor in stress increasing. 연구 목적: 지금까지 성공적인 임플란트 치료를 위해 많은 연구가 진행되어 왔으며, 임플란트 주변 골 흡수 현상에 대한 연구는 매우 관심이 높은 분야 중 하나이다. 이에 본 연구에서는 삼차원 유한요소응력분석을 이용하여 변연골 흡수가 내측연결 임플란트 매식체의 기계적 안정성에 미치는 영향을 간접적으로 확인하고자 하였다. 연구 재료 및 방법: 악골에 식립된 내측연결 형태의 임플란트 매식체에 티타늄 소재의 임플란트 지대주를 지대주 나사로 연결하고 상부에 금합금관을 장착하는 삼차원 유한요소모형을 설계하였다. 0, 1, 2, 3 mm의 변연골 흡수 상태를 적용하고, 교합면 중심에서부터 3 mm 편측에 300 N의 수직 하중을 가하여 임플란트 매식체에 발생하는 최대 주응력을 계산하였다. 결과: 유한요소분석결과 변연골 흡수에 따른 임플란트 매식체의 최대 주응력 분포는 유사한 양상을 보였으며, 임플란트 매식체 상단에서 가장 높은 응력 집중이 나타났다. 최대 주응력은 처음 1 mm 변연골 흡수를 가정하였을 때 가장 크게 증가하였고, 이후 변연골 흡수가 증가할수록 응력은 증가하였지만 응력 증가의 폭은 감소하는 경향을 보였다. 결론: 이러한 결과로부터 내측연결 임플란트에서 매식체 두께가 얇은 경부의 노출은 변연골 흡수로 인한 응력 증가에 가장 큰 원인임을 알 수 있었으며, 매식체의 변형, 균열 및 파절 등의 기계적 실패를 감소시키기 위해서는 이에 대한 외과적, 보철적 고려가 필요할 것으로 생각된다.

Do Yeun Myeung(陶淵明) lived in aPeriod of confusion when Dong Gean(東晋)was ruined and song Dynasty(宋) was founded. As soon Dong Gean fell, he returned home retired from his govermental post. we called him a rural poet and thought him to lead a life in seclusion, but he was the loyal patriot for Gean Dynasty in that he renewed his name Yeun Myeung to Gyam(潛)(meaning of "sunk") and his retirement began at the same time Dong Gean was ruined. He was not inborn hermit but the loyal patriot for Gean Dynasty. His poem "Ode to Hyung-ga"<詠荊軻> expressed his lamentation of the failure of the assassinator Hyung-ga to kill the Emperor Geansi. <秦始皇> This poem reflected the mind of Do His poetical world follwed the teaching of the traditional Confucianism. Do Yeun Myeung was not indulged in Buddhism or Lautzu and Chantzu(老子, 莊子) which had a power at that time. He respected Confucianism and endeavered to practice perfect virtue. In his poem "Drinking 20"(飮酒) he felt sorry that Confucian morality had declined at the period. He quoted Confucian speech in many other poems, and longed for a saint's life. He did not live with decadence when he returned hometown. He engaged in doing farm work by himself, read books and spent his times admiring the eternal nature. He loved natured which embodied the consistant virtue, and wanted to be the pure heart agreed with nature. He liked to drink and to harmonized in nature. His poem "Drinking 5" showed the state of mind which united with nature. Korean scholor Toegea(退溪) adored Do Yeun Myeung, and wrote 20 poems, parody of Do Yeun Myeung's "Drinking 20". As an oriental representative poet Do Yeun Myeung will not be forgotten forever.
