        융합교육(STEAM) 운영 현황 실태 조사 및 미래형 융합교육(STEAM)에 대한 인식 조사

        김현경,김현경,김선경 한국교원대학교 뇌기반교육연구소 2023 Brain, Digital, & Learning Vol.13 No.1

        In this study, the current status of implementation of STEAM education was investigated, and the perception of future STEAM education was investigated. A survey was conducted for teachers of the STEAM Teacher Research Group, and frequency analysis and word cloud keyword analysis were performed on the response data. The key findings are as follows. With respect to current status of implementation of STEAM education, first, the reason for implementing STEAM education was teachers' voluntary efforts and the necessity for future talent cultivation for all elementary, middle and high school teachers. Second, the difficulties in implementing STEAM education are heavy workload, adjustment of class hours, difficulties in securing budget, and lack of understanding of STEAM education for elementary schools. For middle schools, the answers are difficulties in curriculum restructuring and collaborating with other teachers, and the lack of program dissemination, while high schools responded to the lack of curriculum reorganization, administrators' understanding and educational expectations. Third, as a learning method for STEAM classes, the student participation type in which students directly solve problems was mainly used, and the student-led type emphasized in future STEAM education was already applied. Regarding the perception of future STEAM education, first, they were well aware of the main contents of future STEAM education, such as nurturing future talent, chemical fusion, student-led, real-life problem solving, and sympathized with the necessity. Second, difficulties related to the implementation of future STEAM education were teacher competency, teacher understanding, culture creation, and realistic burden. Finally, by synthesizing these opinions, the goals for revitalizing future STEAM education are summarized as strengthening teachers' professionalism, forming a consensus, and creating an environment inside and outside the school. As a specific way to achieve this, professional support for teachers, research and selfdevelopment, change of perception, administrative and financial support, and institutional support were suggested.

        Epidemiology and Clinical Features of Post-Transplant Bloodstream Infection: An Analysis of 222 Consecutive Liver Transplant Recipients

        김현경,박용근,왕희정,김봉완,신소연,임승관,최영화 대한감염학회 2013 Infection and Chemotherapy Vol.45 No.3

        Background: Bloodstream infection (BSI) is a significant cause of morbidity and mortality in liver transplant (LT) recipients. This study aimed to investigate the epidemiology and clinical features of post-transplant BSI in LT recipients. Materials and Methods: The microbiology, frequency, and outcome of post-transplant BSI in the first year after LT were retrospectively analyzed in 222 consecutive patients who had received liver transplants at a single center between 2005 and 2011. The risk factors for post-transplant BSI and death were evaluated. Results: During a 1-year period after LT, 112 episodes of BSI occurred in 64 of the 222 patients (28.8%). A total of 135 microorganisms were isolated from 112 BSI episodes including 18 polymicrobial episodes. The median time to BSI onset ranged from 8 days for Klebsiella pneumoniae to 101 days for enterococci, and the overall median for all microorganisms was 28 days. The most frequent pathogens were Enterobacteriaceae members (32.5%), enterococci (17.8%), yeasts (14.0%), Staphylococcus aureus (10.3%), and Acinetobacter baumannii (10.3%); most of them showed resistance to major antibiotics. The major sources of BSI were biliary tract (36.2%), abdominal and/or wound (28.1%), and intravascular catheter (18.5%) infections. The independent risk factors for post-transplant BSI were biliary complications (odds ratio [OR]: 2.91, 95% confidence interval [CI]: 1.29to 6.59, P = 0.010) and longer hospitalization in the intensive care unit (OR: 1.04, 95% CI: 1.00 to 1.08, P < 0.001) after LT. BSI was an independent risk factor for death (hazard ratio [HR]: 3.92, 95% CI: 2.22 to 6.91, P < 0.001), with a poorer survival rate observed in patients with BSI than in those without BSI (1-year survival rate: 60.0% versus 89.5%, respectively, P < 0.001)after LT. The strongest predictors for death in patients with BSI were hepatocellular carcinoma (HR: 3.82, 95% CI: 1.57 to 9.32,P = 0.003), candidemia (HR: 3.71, 95% CI: 1.58 to 8.71, P = 0.003), polymicrobial bacteremia (HR: 3.18, 95% CI: 1.39 to 7.28,P = 0.006), and post-transplant hemodialysis (HR: 2.44, 95% CI: 1.02 to 5.84, P = 0.044). Conclusions: BSI was a frequent post-transplant complication, and most of the causative pathogens were multi-drug resistant. Biliary complications and BSIs resulting from biliary infection are major problems for LT recipients. The prevention of BSI and biliary complications is critical in improving prognosis in liver transplant recipients.

        데이터베이스권에 대한 재검토 - EU 사례(CV-Online vs. Melons) 및 지침의 개정 동향을 중심으로 -

        김현경 한국저작권위원회 2022 계간 저작권 Vol.35 No.3

        Even in Europe, where database rights(Sui Generis Database Rights) were first created, questions about the utility of these rights have been raised and discussions for revision is going on. We, who benchmarked these European cases at the time, also need to pay attention to the changes in EU. Therefore, in this study, the problems of the database rights were analyzed and future improvement tasks were derived. The results of the s tudy a re a s follows. First, the EU is changing the criteria for judging database rights infringement through the CJEU decision. In order to accommodate the innovation of data, the creation of added value through reuse of users and competitors and the possibility of innovation are accepted as the criteria for judging infringement. We also need to take this into account in our “significant investment” and “determination of infringement”. Second, it is necessary to think about the extension of the exception range of the database right. In Europe, through a separate legislative measure called the Data Act, a wide range of exceptions are being allowed by excluding the database right for databases acquired or created by the use of products or services. This is premised on the premise that the establishment and utilization of databases in various artificial intelligence services, including IoT, is essential anyway, so there is no need to induce investment by guaranteeing sui generis rights. As such, in certain cases, it is necessary to review the introduction of regulations that restrict database rights. Third, like public works, free use of public databases needs to be introduced. Public databases are already trying to create added value through private use through other individual laws. In addition, it is questionable whether the criteria for judging infringement, such as ‘significant investment’ and ‘risk of recovery of investment’, can be applied to the act of creating a database funded by the state finances. Therefore, it is necessary to review the introduction of database rights restrictions on public works. 창작성이 없는 데이터베이스에 대하여 독점・배타적 권리, 즉 데이터베이스권을 최초로 창설한 유럽에서조차 최근 이러한 권리의 효용에 대한 의문을 제기하고 수정 논의가 진행되고 있다. 당시 유럽의 사례를 그대로 벤치마킹한 우리 역시 이러한 유럽의 움직임에 주목할 필요가 있다. 따라서 본 연구에서는 데이터베이스권의 한계를 분석하고 향후 개선과제를 도출하고자 하였다. 연구의 결과는 다음과 같다. 첫째, EU는 CJEU 결정을 통해 데이터베이스권 침해 판단의 기준을 변화시키고 있다. 혁신을 수용하기 위해 이용자・경쟁자의 재사용으로 인한 부가가치 창출, 혁신가능성 등을 침해 판단의 기준으로 수용하고 있다. 우리도 “상당한 투자” 및 “침해의 판단”에 있어서 이러한 점을 고려할 필요가 있다. 둘째, 데이터베이스권의 제한 범위 확장에 대하여 고민할 필요가 있다. 유럽의 경우 데이터법이라는 별도의 입법적 조치를 통해 제품이나 서비스의 이용에 의해 획득 또는 생성된 데이터베이스에 대하여는 데이터베이스권을 제외시킴으로써 광범위한 예외를 허용하고자 하고 있다. 이는 IoT를 비롯한 각종 인공지능 서비스에서 데이터베이스의 구축 및 활용은 어차피 필수적이므로 별도의 권리 보장을 통한 투자유인이 반드시 필요하지 않음이 전제되어 있다. 이렇듯 일정한 경우 데이터베이스권을 제한하는 규정의 도입을 검토할 필요가 있다. 셋째, 공공저작물과 마찬가지로 공공데이터베이스의 자유 이용이 도입될 필요가 있다. 공공데이터베이스는 이미 다른 개별법을 통해 민간의 활용을 통한 부가가치 창출을 도모하고 있다. 그뿐만 아니라 국가재정이 투여된 데이터베이스 제작 행위에 대하여 ‘상당한 투자’ 및 ‘투자 회수 위험’ 등 침해 판단의 기준이 적용될 수 있을지 의문이다. 따라서 공공저작물에 대한 데이터베이스권 제한 규정의 도입이 검토될 필요가 있다.
