산책과 동시활동의 통합이 유아의 언어표현력과 동시감상 능력에 미치는 영향
강연옥(Kang, Yeon Ok),권민균(Kwon, Myn Gyun) 계명대학교 생활과학연구소 2015 科學論集 Vol.41 No.-
The purpose of this research was to examine the effect of integrated activities of walks and poems on young children"s expressive language skills and poem appreciation. The subjects of this study were thirty-six, five-year-old children from two different kindergartens in Gyeongsangbuk-do province. Eighteen children from K kindergarten comprised the experimental group while eighteen children from J kindergarten comprised the control group. The experimental group participated in the integrated activities of walks and poems twice a week for ten weeks, whereas the control group participated only in poem activities using the same poems as the experimental group. Means and standard deviation were calculated. ANCOVA was carried out to find out the differences between the experimental and the control group. The results were as follows. First, there were meaningful differences between the experimental and the control group in terms of young children"s expressive language skills. Second, there were meaningful differences between the experimental and the control group in terms of poem appreciation. In conclusion, the integrated activities of walks and poems are an effective program to improve young children"s expressive language skills and poem appreciation.

Whirl Fire와 Pool Fire의 화염 거동에 관한 연구
오규형,강연옥,이성은 한국안전학회 2004 한국안전학회지 Vol.19 No.3
4-panel of Im height and 45cm width were fixed on the 40cmx40cm bottom plate and the opening of the panel comer was 5cm. Diameter of stainless vessel is 10em and its height is 2cm and it located at the center of the bottom plate. 78mL liquid fuel was filled in the vessel and its depth was lcm. Flame temperature was measured with K type thermocouple, and radiation heat of flame was measured with heat flux meter. Flame height and its behavior was visualized with video camera. and mass burning rate was measured by fuel combustion time. According to the development of fire, flame swirling was begin. From the experiment the mass burning rate was larger and the height of flame was higher than the usual pool fire flame. Flame temperature and heat flux also increased far more than the pool fire. Consequently the swirling air flow through the openings between the panel and thermal buoyance contribute to increase of heat release rate, flame length and mass burning rate.
