본 연구는 국민은행의 주택금융수요 실태조사 자료를 이용하여 일반 서민가구의 주택담보 대출유형, 특히 주택금융공사의 보금자리론으로 대표되는 공공 모기지와 여타 민간은행의 민간 모기지간의 선택에 영향을 미치는 요인을 탐구하였다. 우리는 보금자리론이 출시된 2004년부터 2006년까지의 3개년치의 자료를 투입하여 다항 로짓(Multinomial Logit) 모델 및 중첩 로짓(Nested Logit) 모델을 적용하여 분석하였다. 미국의 실증분석 결과와는 달리 우리의 경우 서민가구들이 공공 모기지 보다는 민간 모기지를 선호하는 것으로 보인다. 그 이유로는 민간모기지 상품의 다양성이나 이자유형 변경옵션과 같은 상품자체에 기인하는 속성과 함께 민간 대출기관의 느슨한 소득 검증(Income verification)과 같은 규제적 특성 역시 중요한 요인인 것으로 분석되었다.

Background Development of genetically modified crops has rapidly increased in last few years. The most widely grown GM crops express genes that confer herbicide tolerance and insect resistance. Detection system of GM crops is important for safety evaluation before its consumption. Objective The purpose of this research is to detect GM crops, especially PAT, in food-samples. Results The bar gene (PAT protein, herbicide resistant) was cloned in pGEX-4T-1 and expressed by E. coli. The high-affinity PAT-specific single-stranded DNA (ssDNA) aptamers were obtained from a random DNA library. MOE docking study was performed to identify the potential binding region of the selected aptamers on PAT. Aptamer-linked immobilized sorbent assay (ALISA) method was used to detect PAT. Conclusion We screened aptamer against PAT for developing an efficient detection method. The selected PAT specific aptamers, HRPA-05 and HRPA-07, showed the distinct target binding behaviors, and detected PAT protein by aptamer-linked immobilized sorbent assay method with high efficiency and selectivity.

목적 : 항균제 오남용으로 인한 내성균의 출현, 약물부작용의 발생 및 약제 비용의 증가는 환자 개인뿐만 아니라 사회적으로 문제가 되고 있다. 본 연구는 항생제의 오남용을 막기 위한 제도의 일환으로 시행한 아미노글리코사이드 사용 제한정책의 비용 효과적인 측면을 조사하고 그람음성간균에 의해 병원성 균혈증이 발생한 환자들을 대상으로 이 정책이 항생제 내성률과 환자 사망률에 미치는 영향을 연구하였다. 방법 : 930병상 규모의 3차 병원인 일개 대학병원에서 아미노글리코사이드 사용제한정책이 시행된 직후인 2002년 3월에서 9월 사이에 그람음성간균(Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Enterobacter cloacae, Enterobacter aerogenes, Serratia marcescens, Stenotrophomonas maltophilia, Burkholderia cepacia)에 의해 발생한 병원성 균혈증 환자 60명(실험군)과, 이 정책이 시행되기 전에 입원한 환자들 중 균주별로 같은 수만큼 선별한 병원성 균혈증 환자 60명(대조군)의 의무기록을 후향적으로 조사하였다. 결과 : 아미노글리코사이드 사용제한정책이 시행된 시기인 2002년 3월에서 9월 사이에 처방된 아미노글리코사이드 사용량 및 비용을 이 정책이 시행되기 전인 2001년 3월에서 9월 사이와 비교한 결과, 아미노글리코사이드의 사용량(antimicrobial utilization density)은 사용제한 후 225.2에서 130.3으로 42% 감소하였고 약제 비용은 44% 감소하였다. 아미노글리코사이드 사용제한 후 병원성 균혈증을 유발한 그람 음성간균의 이 항생제에 대한 내성률은 유의한 변화를 보이지 않았으며 균혈증과 직접 연관된 사망률도 환자의 나이, 성별, 기저질환 및 원발병소 등을 보정할 경우 유의한 차이를 보이지 않았다(40.4% vs. 24.1%, P=0.11). 결론 : 아미노글리코사이드를 5일을 초과한 사용 시 감염전문가의 사전 승인을 필요로 하는 사용제한정책은 아미노글리코사이드의 사용량과 비용을 유의하게 감소시켰다. 또한 이 정책 시행 후 그람음성간균에 의한 균혈증 환자에서 균혈증으로 인한 사망률과 아미노글리코사이드에 대한 내성률은 유의한 차이가 없었다. Objective : To evaluate the effects of an aminoglycoside restriction policy on expenditures for aminoglycosides, antimicrobial resistance rates and clinical outcome of nosocomial bacteremia caused by Gram-negative bacilli (GNB). Methods : Starting in February, 2002, a prior consultation with an infectious disease specialist for using aminoglycoside antibiotics over 5 days was required in a 930-bed university hospital. In retrospective analysis of medical records 7 months after initiation of the aminoglycoside restriction policy, sixty cases of clinically relevant nosocomial bacteremia caused by GNB were found. These bacteremic patients were compared with sixty, species-matched, control patients with nosocomial Gramnegative bacteremia before the policy for total expenditures for aminoglycosides, susceptibility to antibiotics and clinical outcomes of bacteremia. Results : During the same period of 7 months before and after the restriction policy, total expenditures for aminoglycosides decreased by 44% in cost (from 465,030,841 Won to 259,618,337 Won) and the antimicrobial utilization density of aminoglycosides decreased by 42% (from 225,2 to 130.3). On the other hand, the patterns of antibiotic susceptibility and bacteremia-related in-hospital mortality rates after the policy did not show a significant change, compared with those before the policy. Conclusion : Antibiotic restrictions are among the most popular methods to diminish the practice of antibiotic overuse in hospitals. In this study, requirement for prior approval of aminoglycoside use over 5 days led to a significant decrease in the amount and cost of total aminoglycosides without a significant change in susceptibility patterns and bacteremia-related mortality rates.

One of the major reasons for what Hyonch'ungsa was built is handing down the patriotic spirit of General Lee, Sun-sin from generation to generation. It was designated as a historic site (National No. 155) by our government and has been visited by many people including students and tourists. This paper is to explore some problems revealed against the spirit of Chungmugong (General Lee's added name) with realtion to the plants in the sacred area of Hyonch'ungsa. 1. 21.33% of the plants came from foreign countries. They are all considered unproper as historic site plants. 2. Above all, 26.83% of plnats which were from Japan could have diluted the symbolic meaning of Chungmugong. 3. Most of plants around the main building and the relic pavilion which are from abroad including Japan could be come into serious question. 4. Large clusters of exotic plants have tendency of swallowing up the magnificient appearance of the precinct buildings. 5. The growth of the plants close to the buildings keeps the dignified appearance shrunk. 6. The high ratio of planing evergreen trees may deprive us a strong sence of a season. 7. Some kinds of shade trees could be recommended around the thru-way so as to provide us with comfortableness and agreeableness especially in summer times. It is suggested that the plants of foreign origin have to be substituted for those of our own in order to keep the proper meaningness of Hyonch'ungsa.

Patients with obstructive sleep apnea syndrome (OSAS) exhibits repetitive, prolonged episodes of apnea during sleep with serious nocturnal and diurnal physiologic derangements. With their physiologic derangements. OSAS have many implications for the anesthesioloists. First, OSAS patients are sensitive to all central depressant drugs, with upper airway obstruction or respiratory arrest occurring even with minimal doses. Thus sedative and opioid premedication should be omitted or as should the intra and postoperative use of opioids be limited or avoided. All anesthetic drugs should be administered by titration to desired effect, preferably using short-acting drugs. When feasible, continuous regional anesthesia using a catheter is the technique of choice. Where possible nonopioid analgesics or local anesthetics should be used for postoperative analgesia. Perioperative monitoring for apnea, desaturation, and dysrhythmia is essential. Secondly OSAS patients have a potentially difficult airway. Awake intubation is the safest approach to airway control. Extubation should only be tried in the fully conscious patients with intact upper airway function and under controlled situations. Thirdly the cardiorespiratory complication of OSAS and the presence of the associated diseases are adversely influence anesthetic management. The purpose of this article is to outline the potential problems encountered in anesthetic management of adult OSAS patients, and to suggest a practical approach for anesthesia both for incidental and specific procedures.
