  • 목 적 : 신생아 사망 및 이환의주요 원인인 패혈증의 치료에 있어서 적절한 항생제의 선택은 항생제 내성을 줄이고 다약제 내성 균주의 출현을 방지할 수 있다. 이제 저자들은 단일 신생아중환자실에서 경험한 신생아 패혈증 빈도와 원인균 및 항생제 감수성 변화를 지난 10년간에 걸쳐 조사하였다. 방 법 : 1998년 1월부터 2007년 12월까지 본원 신생아 중환자실에 입원한 환아 중 혈액 배양 검사상 균이 동정되었던 환아들을 대상으로 의무기록을 통해 1998년부터 2002년까지를 전반기, 2003년부터 2007년까지를 후반기로 구분하여 각 발생 시기에 따른 패혈증의 원인균과 항생제 감수성을 후향적으로 분석하였다. 결 과 : 315명의 환아가 총 350례의 패혈증을 경험하였으며, 조기 패혈증의 원인균으로는 전반기는 S. epidermidis, S.aureus, P. aeruginosa, Enterobacter cloacae, 후반기에는 S. epidermidis, E. cloacae가 흔하게 검출되었다. 후기 패혈증의 경우는 전반기에는 coagulase negative S. epidermidis, S. aureus, K. pneumoniae가 전반기와 후반기 모두에서 가장 흔하게 배양되었다. 다약제 내성균에 의한 패혈증은 엄격한 감염관리를 시행한 이후 감소하는 경향을 보였다. 그람 양성균의 경우 penicillin, ampicillin, 그리고 cefotaxime에 대해 전후반기 모두에서 0-20%의 낮은 감수성을 보였다. 그람 음성균의 경우는 Enterobacter spp의 amikacin에 대한 감수성이 전반기(15.8%)에 비해 후반기(37.5%)에 증가하는 양상이었다. P. aeruginosa는 amikacin에 대해 전반기 33.3%에서 후반기 20%로 감수성이 감소하였다. P. aeruginosa를 제외한 그람 음성균은 cefotaxime에 대해 50-60% 정도의 항생제 감수성을 보였다. P. aeruginosa를 제외한 그람 음성균의 경우 imipenem과 ciprofloxacin에 대해 80% 이상의 감수성을 보였다. 결 론 : 지난 10년간의 신생아 패혈증의 원인균과 항생제 감수성의 변화양상을 확인하였으며, 이는 경험적 항생제 사용을 선택하는데 도움이 될 것으로 생각된다. 전반기에 비해 후반기에는 엄격한 감염관리를 통해 다약제 내성균에 의한 패혈증 및 전체 신생아 패혈증의 발생이 현저히 감소하였다. 따라서 신생아 패혈증의 발생과 감염에 의한 사망을 줄이기 위해서는 적절한 항생제 선택과 더불어 지속적인 감염관리가 필요할 것으로 사료된다.

  • Clinical practice in nursing education provides an opportunity for students, through the process of ap-plying theoretical knowledge to practice, and to learn nursing skills as well as being socialized into nursing and as such decrease the reality shock of actual nursing practice. Because of a shortage of nursing faculty, the job of achieving the objectives of the clinical practice had been turned over to the head nurses. This resulted in many problems, such as, unclear location of responsibilities and inadequate feedback from head nurses. Therefore this study was done to introduce and evaluate the use of preceptors as a way to minimize the above problems, and to maximize the achievement of the clinical practice objectives. Using an adaptation of Zerbe's (1991) three-tiered team model, clinical practice was done using a preceptor, a head nurse and a clinical instructor, each with different and well defined roles. The subjects of this study were 67 senior students of the College of Nursing of Y University in Seoul whose clinical practice in adult nursing was carried out between May 1, 1994 and December 8, 1994. There were 22 preceptors who had at least two years of clinical experience and who were recommended by their head nurses. They were given additional education on the philosophy and objectives of the College of Nursing, on communication skills, on the theory and practice of education, and on nursing diagnosis and education evaluation. The role of the preceptor was to work one-to-one with students in their practice. The role of the head nurse was to supervise and evaluate the preceptors. The role of the clinical instructor was to provide the education program for the preceptors, to provide ad-vice and suggestions to the preceptors and to maintain lines of communication with the college. With each of these roles in place, it was thought that the effectiveness and efficiency of the clinical practice could be increased significantly. To evaluate the effectiveness of the preceptorship, the three - tiered model, Lowery's Teacher Evaluation Opinion Form translated and adapted to Korea was used to measure student statisfaction. The Clinical Practice Compentency Evaluation Tool developed by Lee et ai was also used to measure student competencies. The results of this study are as follows 1. The satisfaction with clinical practice was higher with the introduction of the perceptors than it was before they were used. (t=-5.96, p=<.005) 2. The clinical practice competencies were higher with the introduction of the preceptors than it was before they were used(t=-5.l3, p<.005) 3. In order to analyze areas not measured by the quantitative tools additional analysis of the open questions was done. The results of this analysis showed that : 1) The students felt positive about their sense of security, confidence, handling of responsbility, and being systematic. They also felt positive about improvements in knowledge, opportunities for direct care, and socialization. 2) The students felt negative about the technical part of their role, lack of knowledge by the preceptor, unprofessional attitudes on the part of the preceptor, difficulty in the role of the professional nurse(student). 3) The preceptors felt positive about their responsibility, motivation, and relationship with the college. 4) The preceptors felt negative about their bur-den. Introduction of the preceptorship model will lead to change and improvement in the negative factors discussed above, solve problems in the present clinical education system, increase continuity in the education of the students, help with socialization of the students and motivation of the preceptors to up-grade their education and increase their confidence. These objectives must be obtained to further the development of professional nursing, and thus, making the preceptorship a reality is our job for the future.

  • 최신 정보통신기술이 다양한 분야에 접목되면서 우리의 일상은 급격한 속도로 변화하고 있으며, 스마트시티 개념이 확산되고 있는 반면, 조경분야에서는 기술진화에 의한 사회변화에 대비하려는 노력이 부족한 실정이다. 이에 본 연구는 스마트공원의 개념을 정립하고, 공원 관련 스마트 기술 도입 현황을 파악하며, 기존에 조성된 스마트공원의 서비스에 대한 이용자의 인식과 활용도를 파악함으로써 향후 스마트공원 조성을 위한 기초자료를 제공하는 것을 목적으로 하였다. 이를 위해 관련 문헌 및 선행연구 고찰, 전문가 토론, 국내외 사례조사를 실시하였으며, 국내 최초로 스마트공원 시범사업이 시행된 대구시 국채보상운동 기념공원의 이용자를 대상으로 스마트공원에 대한 인식 정도와 서비스 만족도를 조사하였다. 연구결과, 스마트공원이란 다양한 첨단 기술을 활용하여 이용자의 공원 체험을 향상하고, 효율적으로 공원을 유지 관리하며, 도시가 직면한 사회 및 환경문제를 해결하는 지속가능한 공원으로 정의할 수 있다. 현재까지 공원에 도입된 스마트기술은 인공지능 CCTV, 스마트 가로등, 미세먼지 알림장치 등 주로 안전 및 환경 분야에 집중된 것으로 나타났다. 실제 이러한 기술이 도입된 국채보상운동기념공원 이용자들을 대상으로 한 인식조사 결과, 홍보 부족 및 관리인 편의 중심의 기술도입으로 인하여 실제 이용자의 인식 정도는 매우 낮은 편이었다. 특히 역사성 있는 공원의 역사정보 전달을 위한 AR서비스 활용이 가장 저조한 반면, 태양열 벤치나 WiFi 등의 시설의 활용도가 가장 많은 것으로 조사되었다. 향후 스마트공원 조성 시 안전 및 환경 관리, 편의성 증진을 위한 서비스 뿐 아니라, 이용자가 체감할 수 있고, 이용자 요구에 맞는 다양한 콘텐츠 개발을 위한 노력이 필요할 것이다.
