The recent global warming may be estimated to give lots of impacts to the human society and biosphere of influencing climate change included by the natural climate variations through the human activity which can directly and/or indirectly play a major role of total atmospheric composition overall. Therefore it currently appears evidences such as hot wave, typhoon, and biosphere disturbance, etc. over the several regions to be influenced by global warming due to increasing the concentration of greenhouse gases in the atmosphere through inducing forest destruction, fossil fuel combustion, greenhouse gases emission, etc. since industrial revolution era. Through the working group report of IPCC (Intergovernmental Panel on Climate Change) for climate change was analyzed by the individual country's current status and figure out the important issues and problems related to the future trend of climate change science with advanced countries preparedness and research, In this study, the first working group report of IPCC focuses on those aspects of the current understanding of the physical science of climate change that are judged to be most relevant to policymakers. As this report was assessed and analyzed by including the progress of climate change science, the role of climate models and evolution in the treatment of uncertainties. This consists of the changes in atmospheric constituents(both aerosols and gases) that affect the radiative energy balance in the atmosphere and determine the Earth's climate, considering the interaction between biogeochemical cycles that affect atmospheric constituents and climate change, including aerosol/cloud interactions, the extensive range of observations snow available for the atmosphere and surface, for snow, ice, and frozen ground and for the oceans, respectively and changes in sea level, the paleoclimate perspective and assessment of evidence for past climate change and the extension, the ways in which physical processes are simulated in climate models and the evaluation of models against observed climate, the development plans and methods of improving expert and building manpower urgently and R&D fund expansion in detail for climate change science in Korea will be proposed.

본 연구는 근거기반간호를 지원하기 위해 펍메드를 통한 체계적 문헌검색 사례를 제시하고자 시도되었다. 연구방법: 유치도뇨관 감염예방 가이드라인을 확인하기 위하여 다섯가지 검색전략을 수행하였고, 문헌은 1980-2010년, 영어, 인간연구로 제한하여 검색하였다. 검색결과는 추출된 문헌 수, 관련 문헌 수, 검색의 민감도와 정확도를 통해 비교분석하였다. 연구결과: 다섯가지 검색전략에 따라 검색결과를 각각 다르게 나타났다. 추출된 문헌 수는 19-141개, 관련 문헌 수는 3-6개였다. 민감도가 가장 높은 검색전략은 ``기본검색``, ``MeSH 용어, textword, 및 검색필터 활용 검색``이었고, 정확도가 가장 높은 방법은 ``MeSH 용어와 제한기능 활용 검색``이었다. 결론: 펍메드에서의 ``기본검색``은 바쁜 임상현장에서 유용한 근거검색 방법이나, 간호사들은 효과적이고 효율적인 문헌검색을 위해 MeSH 용어, textword, 제한기능, 연구설계에 따른 검색필터 등을 다양하게 활용할 수 있어야 할 것이다. Effective literature searching is essential to support evidence-based nursing. The aim of this study was to present our recent systematic search experience to identify guidelines in PubMed for prevention of catheter-associated urinary tract infections. Methods: Five approaches to the literature search via PubMed were employed. The searches were restricted to items published from 1980 to 2010, for patients admitted to hospital, and in the English language. The search results were compared using the number of records and relevant items, and the sensitivity and precision of each search strategy. Results: The individual approaches retrieved 19-141 of records and 3-6 of relevant items. Sensitivity ranged from 37.5% to 75.0% with the highest values for simple searches and a search combining MeSH terms and free textwords with a methodological search filter. Precision varied from 4.3% to 21.7% and the highest precision was found for MeSH terms with limits feature. Conclusion: The simple search in PubMed is an appropriate way for nurses in a busy clinical practice to search the literature for evidence. However, several approaches using MeSH terms, free textwords, limits feature or methodological search filters are also required to have more efficient and better informed search results.

Purpose: The purpose of this study was to identify nursing activities and to analyze patient outcomes related to indwelling urinary catheterization. Method: A review was done of 628 medical records from five units for patients admitted between January 1 and June 30, 2006. Twelve nurses who worked in the same units were interviewed. Results: In the interviews, nurses reported considering several non-invasive interventions prior to catheterization but there were no medical records of this activity. Results from the in-depth interviews showed that infection control activities such as urinary bag management were conducted but again there were no medical records. Seventy-five percent of the catheters were removed without prescription. In the medical records there were no notes for approximately 15%, on the time of first voiding and 80%, on volume of first voiding after removal of catheter. There was a significant difference in hospitalization days between the group catheterized for 5 days or less and the group catheterized for 6 days or more. Conclusion: Results indicate a need to close the gap between recorded and described activities and between current and best evidence based practice. Further study is needed to develop a standard recording system and guidelines related indwelling catheterization to decrease the gaps identified in this research.

A bright band means that the intensity of radar echo is more exaggeratedly displayed than the real amount of rain due to the permittivity difference of raindrop at the altitude under the layer of 0℃ (melting layer). When a bright band appears like as a more exaggerated echo, the value of the forecast amount of precipitation is overestimated than a real one. But even though the amount of precipitation is zero or less than 1.0mm in the regions where the bright band shows up, the error of forecast has occurred. The new method to distinguish between bright bands by making use of the radar image materials of the duel polarization radar installed at the weather radar research center has been developed. In the case studies, there were difficult to make a clear distinction of the altitudes on which bright bands appeared on the ZDR imagery, and the scope with a negative (-) value showed up on the very upper altitude of the altitude on which bright bands appeared. In the RHOHV imagery, while the correlation of the altitude on which bright bands appeared was lower relatively. In the KDP imagery, its value of the altitude on which bright bands appeared was higher in comparison with thatt of other altitudes, and the value with the negative (-) value turned up on the upper and lower altitude of the altitude on which bright bands appeared in both altitudes. Finally, in the PID imagery, the type of raindrop consisting of the altitudes on which bright bands appeared turned up as a form of grain, small hail, and hail. Of all the image materials used in the analysis work, bright bands showed clearly up in the RHOHV and KDP images.

Purpose: The aim of this study was to find the effect of collaborative learning on problem-solving processes according to the level of metacognition, after adopting collaborative learning to clinical practice of nursing management. Method: Senior college students participated in this study. 90 students who was involveled in high level metacognitive group and another 88 students in low level metacognitive group. The data was collected from 2003 to 2005. The process of collaborative learning was categorised in 4 steps. The data were analyzed using t-test, ANCOVA, paired t-test. Results: 'There will be a distinction between the low and high metacognition groups after application of collaborative learning' was rejected, 'In the high level metacognitive group, the problem-solving ability will also increase after application of collaborative learning than before application' was supported. 'In the low level metacognitive group, the problem-solving ability will increase after application of collaborative learning than before application' was supported. Conclusion: The results showed that with collaborative learning, the problem-solving ability of learners with different levels of metacognition is improved.
