When people are involved in real estate transactions, most of them draw up dual agreements in order to evade taxes on real estate in Korea. Buyer and seller make two agreements in which the sale price and the lower price than that are respectively written. And they can evade taxes by reporting the agreement with the lower price to the government office concerned. Making dual agreements gives rise to the inequity of taxation, the speculation in real estate, and the urban housing problem. Thus, the central government has made efforts to prevent them from making dual agreements without any noticeable result. In this study, we proposed introducing a real estate information system, which controls and manages all information about real estate transactions. The system will achieve the equity of taxation through building up the database of sale prices on land and buildings.
전체 적층판 접근법을 이용한 섬유강화 적층 복합재 차체 구조물의 파손평가 연구

섬유강화 적충 복합재 차체 구조물의 강도를 평가하기 위해 전체 적충판 접근방법의 적용을 제시하였다. 180km/h급의 한국형 틸팅열차의 하이브리드 복합재 차체 기본설계를 검증하기 위해서 구조해석을 수행하였으며 또한 복합재 적충판의 강도를 구하기 위해 기계적 물성시험을 수행하였다. 결과적으로, 한국형 틸팅열차의 복합재 차체 구조물에서 발생하는 웅력값들은 모두 파손영역의 안전한 범위 내에 존재하였으며 전체 적충판 접근방법은 초기 기본설계 단계에서 하이브리드 복합재 차체 구조물의 파손을 예측하는 데 매우 유용함을 증명하였다. In order to evaluate the strength of carbody structures of railway rolling stock made of lafninated fiber-reinforced composite materials, total laminate approach was introduced. Structural analyses were conducted to check the basic design of hybrid composite carbody structures of the Korean Tilting Train express(TTX) nith the service speed of 180km/h. The mechanical tests were also conducted to obtain strengths of composite laminates. The results show that all stress components of composite carbody structures are inside of failure envelopes and total laminate approach is recommended to predict the failure of hybrid composite carbody structures at the stage of the basic design.

Vehicle dynamic behavior should be investigated to establish the track irregularity criteria because they have an impact on vehicle dynamic behavior. The influence of vertical alignment on running behavior and safety for KTX was instigated by numerical analysis among track geometry quality parameters such as vertical alignment, lateral alignment, twist and track gauge in this paper. The wavelength and amplitude of vertical alignment were considered in scenario of this numerical analysis. This research is based on just numerical analysis and the final result which include measurement will be published in the future.

저자들은 3개월간 지속된 발열을 주소로 내원한 영구형 박동 조율기가 있는 환자에서 99mTc-HMPA0 백혈구 스캔상 상대정맥에 위치한 박동 조율기 전극에 염증소견이 관찰되었고 혈액 배양 검사상 Actinobacillus actinomycetemcomitans이 동정되어 이 미생물에 의한 박동 조율기 전극 감염으로 진단하고 박동 조율기의 제거없이 항균제만으로 성공적으로 치료된 증례를 문헌 고찰과 함께 보고하는 바이다. A 73-year-old man was admitted for intermittent episodes of fever and chills for 3 months. He had been implanted with a permanent pacemaker to control tachy-bradycardia syndrome 7 months before admission. Blood cultures were positive for Actinobacillus actinomycetemcomitans and a 99mTc-hexamethylpropylene amine oxime (99mTc-HMPAO) WBC scan revealed inflammation on the pacemaker lead in extracardiac site. Oral examination revealed several dental caries. The patient was treated with intravenous ceftriaxone, followed by oral ciprofloxacin without removal of the infected pacemaker lead. He was doing well 10 months without febrile episodes after discontinuation of antibiotics. This report describes the first case of A. actinomycetemcomitans bacteremia associated with a pacemaker lead and localized by 99mTc-HMPAO WBC scan
Staphylococcus lugdunensis에 의한 감염성 심내막염 1예

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS) that is commonly found on the human perineal skin. Contrary to other CNS, S. lugdunensis is a rare contaminant in cultures and has the potential to cause clinically significant infections, including infective endocarditis. Infective endocarditis due to S. lugdunensis have been known to resemble endocarditis due to S. aureus because of its aggressive clinical course and high mortality. We report a case of infective endocarditis caused by S. lugdunensis in a 21-year-old woman. She was cured of the infection with surgical and antibiotic therapy. S. lugdunensis에 의한 감염성 심내막염은 국내에서보고가 없었던 매우 드물지만 다양한 합병증과 높은 사망률을 보이는 감염증이다. 저자들은 S. lugdunensis가 수술적 치료와 항생제 치료로 완치된 감염성 심내막염 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
