금속활자, 고려청자, 로켓을 비롯한 화약무기 그리고 각종 천문기기 등 세종시대의 우리나라 과학기술은 세계 최고의 수준이었다. 우리나라가 그동안 경제발전을 이룩해 선진국의 문턱에 올라선 것도 바로 우리 민족의 과학에 대한 우수한 창조력이 뒷받침되었기 때문이다. 연구소에 몸담고 있는 과학인들의 사기를 높여 세종시대의 과학번영을 재현토록 하는 획기적인 정책이 아쉽다.

Purpose: Use of emergency rooms (ERs) has increased considerably in Korea. This increase has caused overcrowding and has increased the burden on ER services, created a lack of continuous service provided by ERs, and raised costs. The objective of this study was to examine the characteristics of ER use for urgent and non-urgent cases in 2009-2011. Methods: In this multivariate analysis, we included data collected from the 2009-2011 Korea Medical Expenditure Panel Survey to assess independent factors associated with ER use in non-urgent settings. We consecutively included patients ≥19 years who had completed the survey until 2011. Results: Among the 10,428 respondents, 19.1% of patients had used ERs. Patients who had used EDs were less likely to have attended graduate school (high school: odds ratio [OR], 0.78 [0.63-0.98]; university: OR, 0.69 [0.54-0.89]) or have chronic disease (OR: 0.68 [0.60-0.78]). In addition, patients who did not have a usual source of care (OR, 0.78 [0.70-0.87]) or those who did not have private insurance (OR, 0.86 [0.74-0.99]) were less likely to use ERs. In the 1,994 cases of ER use, however, the any factors were not affected in the non-urgent ER use group. Conclusion: The number of patients who used ERs has increased, and there were no significant differences in ER use between non-urgent and urgent patients. ERs may have been used for non-urgent cases owing to other reasons. Further studies on the reasons for non-urgent ER use and development of urgent patient criteria are required.
