Experiments were carried out to know some physiological characters of several rice varieties such as Suweon 213-1, Suweon 214, Palkweng, Akibare and Nongbaek. In experiments, total standing crop, leaf area and total net production of dry matter were higher in the variety of Suweon 213-1 than the other varieties. RGR, NAR and CGR showed the highest at heading period of Suweon 213-1 than the other varieties. Efficiency of solar energy utilization also showed the highest through the entire growing period of Suweon 213-1. The amount of net production and dead parts could be estimated by the successive application of the productive structure.

To investigate the effect of light pretreatment on photosynthetic characteristics of leaf blade of rice, 2 varieties of japonica type and 2 varieties of tongil type were grown under 30% or 70% shading conditions from tillering stage to heading stage. Shading treatment of 70% at the heading stage produced low dry matter, and higher LAR and SLA compared with other combination of shading treatment and growing stage did. Photosynthetic activity was lower in order of 0%, 30% and 70% shading treatment under the low light intensity(5Klux) but significantly high in 30% shading treatment under the high light intensity (33Klux) at tillering stage. Photosynthetic activity under low(5Klux) and high(33Kluk) light intensity were higher in order of 70%, 30% and 0% shading treatment at heading stage. Respiration /photosynthesis ratio was lower in shading treatment than in control. CGR, RGR and NAR decreased in shading treatment. Shading treatment reduced the number of ripened grain per panicle and decreased the harvesting index.

In this paper, we examined factors that influenced light pollution in Korean national parks during peak and off-peak tourist seasons. Cloud-and moonlight-free nighttime satellite images that were collected during October 2012(for peak season) and January 2013(for off-peak season) by the Day and Night Band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor were used to estimate the levels of light pollution in 19 national parks (excluding the Bukhansan and Mudeungsan National Parks). Bootstrapping regression analyses were conducted to examine the effects of socioeconomic and policy factors on light pollution in the study national parks for peak and off-peak tourist seasons, separately. The characteristics of light pollution in the national parks varied by season. During the peak tourist season, light pollution in the national parks were affected more by night lights nearby the parks than those within in the parks, while in the off-peak season, light sources in the parks were more important. Scattering of light emitted from hotels and other recreational facilities outside the parks that led to the sky glow effect can be attributed to the greater impact of night lights nearby the parks during the peak season. This result suggests that regulating light pollution nearby the park areas is needed to mitigate light pollution in the national parks, especially in a peak tourist season.

흡수식 2중 효용 냉온수기의 개발 현황을 소개하고자 하며, 흡수식 관련 연구개발이 보다 활성화되는 방향을 제시하고자 한다. 하절기 및 동절기의 중대형 빌딩의 냉난방 부하 대응에 흡수식 냉온수기가 차지하고 있는 비율이 높음으로 흡수식 냉온수기의 고효율화가 경제 및 산업적으로 건물 에너지 절감 및 국가 전체 가스 에너지 절약에 미치는 파급 효과는 매우 크다. 흡수식냉동기는 근본적으로 오존파괴의 문제가 없는 냉매를 사용하고 있고, 고급연료인 LNG를 주로 사용하고 있기 때문에, 지구온난화 유발물질인 $CO_2$ 배출량이 다른 연료에 비해 작다. 아울러 극소량의 공해물질(Nox, Sox)을 방출하며 공해문제를 별로 발생시키지 않기 때문에 흡수식냉동기의 연구개발을 거의 하지 않은 서방 선진국에서도 환경친화적인 흡수식 제품에 대한 관심이 최근에 급증하고 있다.(중략)
