The purposes of this study were to review the present conditions and issues of the in-industry training of vocational high school teachers in Korea and suggest desirable ways to operate in-industry training programs for vocational high school teachers in order to empower them to meet the increasing demands of educational and industrial circles. In order to achieve these goals, authors a) analyzed policies, laws, current status, and problems related to training systems of vocational high school teachers, b) reviewed the training systems of vocational high school teachers in major advanced countries, c) held interviews with 16 city and provincial education agencies in charge of management of field training programs for vocational high school teachers, and d) performed needs analysis by interview with 16 industries that were currently managing and holding field teacher training programs. Based on the analysis, we proposed strategies to the field training programs of vocational high school teachers.

Purpose: To improve outcome of severe trauma patient, the shortening of transport time is needed. Although helicopter emergency medical services (HEMS) is still a subject of debate, it must also be considered for trauma system. The aim of this study is to assess whether transport method (HEMS versus ground EMS) is associated with outcome among inter-hospital transport. Methods: All trauma patients transported to regional emergency center by either HEMS or ground EMS from September 2011 to September 2014. We have classified patients according to two groups by transport method. Age younger than 15 years and self-discharged patients were excluded. Results: A total of 427 patients were available for analysis during this period. 60 patients were transported by HEMS and 367 patients were transported by ground EMS. HEMS group had higher mortality than ground EMS group (23.3% vs 3.5%; p<0.001), and included more patients with excess mortality ratio adjusted injury severity score (EMR-ISS) above 25 (91.7% vs 48.8%; p<0.001). In the multivariable regression analysis, HEMS was not associated with improved outcome compared with ground EMS, but only EMR-ISS was associated with a mortality of patients (odds ratio, 1.06; 95% confidence interval, 1.04-1.09). Conclusion: In this study, helicopter emergency medical services transport was not associated with a decreased of mortality among the trauma patients who inter-hospital transported to the regional emergency center.

본 연구는 ‘후지/M.9’와 ‘홍로/M.9’가 재식된 사과원에 바람이나 우박을 막기 위해 사용되는 망(구멍 크기 : 2×2mm)을 수관상부에 색상별로 백색과 청색을 나누어 설치한 후 햇빛의 차광정도 및 생육환경 차이 등에 따른 과실품질 변화를 조사하였다. ‘후지’ 사과의 경우 대기온도 34.8℃인 오후 2~3시경의 과실표면 온도를 측정한 결과, 무처리는 40.0℃로 가장 높았고, 청색 방풍망과 백색 방풍망 처리구는 각각 34.9℃, 36.6℃로 크게 낮았다. ‘홍로’에서는 무처리구가 44.2℃일 때, 청색 방풍망 처리구는 38.3℃, 백색 방풍망 처리구는 38.5℃를 기록하여 ‘후지’와 마찬가지로 온도 경감효과를 보였다. ‘후지’의 과피색차를 조사한 결과, 과피적색도(a*)는 무처리구가 16.5, 청색 방풍망 처리구는 18.0였으나, 백색 방풍망 처리구는 19.3으로 가장 높은 값을 보였다. ‘홍로’에서도 백색방풍망 처리구가 적색도가 34.9로 무처리구 28.1에 비해 유의하게 높은 적색도 발현을 보였다. 일소피해 조사결과, ‘후지’에서 청색 방풍망 처리구 3.8%, 백색 방풍망 처리구 4.2%로 무처리구 9.4%에 비하여 크게 경감되었고, ‘홍로’의 경우는 청색 방풍망 처리구는 8.8%, 백색 방풍망 처리구는 12.4%로 무처리구 28.8%에 비하여 일소발생이 현저히 감소하였다. 이 같은 결과는 처리별 자외선 수치를 측정하였을 때 무처리 구간의 자외선 값에 비해 청색 방풍망 처리구에서 유의하게 낮아 방풍망 처리에 의한 자외선 차단 효과에 의한 것을 확인할 수 있었다. In Yesan-gun, Korea"s main apple-producing region, the area of apple cultivation and yield are declining. In particular, the worsening quality of fruits due to unusually high temperatures amid recent climate change has also become a major challenge for apple orchards located on flatlands. The objective of this research is to investigate quality changes of apples according to different growing environments, depending on the shade of the sun, by covering the trees with different colors of wind nets. A white and blue wind nets with a hole size of 2 × 2 mm is installed on two experimental trees, 17-year-old ‘Fuji’ and ‘Hongro’, which are planted 1.5 m × 3.5 m in the north-south direction. Treatment of wind nets effectively lowered fruit surface temperature regardless of apple variety. When measuring the temperature of the fruit surface at 2 pm, the temperature of the air was 34.8°C, but the ‘Fuji’ of the untreated blocks was the highest at 40.0°C, while the blue wind net and the white wind net were significantly lower at 34.9°C and 36.6°C, respectively. In ‘Hongro’, the results showed that the surface temperature was effectively lowered by recording 38.3°C for the blue wind net and 38.5°C for the white wind net treatment when the untreated one was 44.2°C. According to the color difference in ‘Fuji’, the skin redness (a*) was the lowest with untreated control at 16.5, but the blue and white wind net treatment higher at 18.0 and 19.3, respectively. In ‘Hongro’, the white wind net treated fruit also showed a much higher skin redness than the untreated control of 28.1, showing much higher a* of 34.9. Sunburn damage in ‘Fuji’ apples amounted to 9.4% in untreated control. However, the blue and white wind net treatment revealed to 3.8% and 4.2%, respectively. In ‘Hongro’, those damage in the fruits treated with blue or white wind net, accounted for only 8.8% and 12.4%, respectively, significantly lower than 28.8% occurrence of untreated one. And, these results were understood to be the result of low UV radiation being blocked by the treatment of wind nets.
