2011년 올 여름은 그 어느 해보다 비로 인한 피해 손실이 직 간접적으로 크게 우리 국민들을 아프게 하고 있다. 많은 지역에서 피해가 발생했지만 우리나라 수도 서울이 그것도 랜드마크 지역으로 많은 사람들이 거주하기를 희망하는 소위 강남권에 위치한 주거지에서 산사태로 인해 많은 인명피해가 발생했다는 것에 묘한 느낌이 든다. 이것이 자연재해든지 인재든 간에 환경변화에 대한 준비가 필요하다. 양계장도 환경변화에 따른 사양관리로 생산성 증대를 이루길 바란다.

지형에 의한 기온, 습도, 풍향과 풍속과 같은 기상요소의 변화를 알아보기 위해 계곡내부, 계곡 입구, 도심에서 기상요소를 특별 관측한 결과를 요약하면 다음과 같다. 기온과 상대습도는 측정값의 차이는 지역에 따라 있었지만, 각 지점간의 상관계수는 높게 측정되었다. 반면에 풍향과 풍속은 각 지역 사이의 절대값 차이가 많이 났으며 상관도 역시 상대적으로 낮았다.

대기 중에 분포되어 있는 다양한 크기와 종류의 에어로졸은 산업의 발전과 급속한 인구의 증가로 인해 가중되고 있으며, 특히 이로 인해 도심지역의 시정감쇄에 큰 영향을 미치고 있다. 특히 도시지역의 대기 중 미세 입자(PM2.5)의 시정감쇄에 대한 영향은 거대입자에 비하여 지배적인 것으로 나타난다. 그 과정에서 대기중 입자의 광학적인 성질 뿐 만 아니라 기상적인 변동 특히 온도와 습도에 의한 시정의 변화는 큰 영향을 받고 있다. (중략)

무더운 여름 날씨가 끝나면 낮과 밤의 일교차가 큰 환절기인 가을철을 맞이하게 된다. 특히 면역능력과 체력이 낮은 어린 가축들은 환경(온도, 풍속, 습도 등)의 변화에 의한 대사불균형 스트레스를 받기 때문에 각별한 관리를 통해 생산성 저하와 질병을 예방해야 한다. 아침 저녁으로 바깥의 찬 공기에 노출되지 않도록 차단하며, 낮에는 충분히 환기를 해주고, 밤에는 보온이 되도록 한다.

Currently, there are very few studies on Korean wall paintings. Therefore, this study discusses the current conditions of wooden paintings and the characteristics of the adhesive agent in the painting layer separation. Korean land pine was chosen as the support, while white oysters shells, orpiment, red ocher, Noerok, and azurite were used as pigments. With four adhesive agents, including animal glue, Gelidium, methyl cellulose, and PVAc (caparol binder), a comparative experiment was conducted, by dividing them into two concentrations, of 0.5% and 1.5%. The temperature, humidity, and ultraviolet rays, which are contributing environmental factors in cultural assets after fixing, were artificially investigated. After deterioration, observed color difference, fixing, and the surface. Results showed that the animal glue strongly fixing all the colored layers compared to the other adhesives; however, azurite had a partial change when used outdoors. With Gelidium, which functioned similar to animal glue, the azurite was affected by the ultraviolet rays; nevertheless, despite the variations in temperature and humidity, it had the best gripping force compared to the other adhesive agents. Methyl cellulose was glossy at a high concentration, and was relatively strong against rapid changes in temperature and humidity. PVAc significantly reduced the binding force, compared to other adhesive agents.

Dryers becoming commercially available for experimental and industrial use are classified to general drying oven, hot-air dryer, vacuum dryer, freezing dryer, etc. and kinds of them are various from the function, size and volume, etc. But the moisture measurement is not applied although it is important factor for the quality control and the performance improvement of products, and then now is very passive because the weight is weighed arbitrarily after dry-end. Generally the method for measuring moisture is divided by a direct measurement method and a indirect measurement method, and the former such as the change of weight or volume on the front and rear of separation of moisture, etc. is mainly used. Relatively a indirect measurement is very limited to apply due to utilize measurement apparatuses using temperature conductivity and micro-wave etc. In this research, we easily designed the moisture measurement system using the open-source based Arduino, and monitored moisture fluctuations and weight profiles in the real-time without the effect of external environment. Concretely the temperature-humidity and load cell sensors were packaged into a drying oven and the various change values were measured, and their sensors capable to operate 60℃ and 80℃ were selected to suitable for the moisture sensitive materials and the food dry. And also the performance safety using the organic samples of banana, pear, sawdust could be secured because the changes of evaporation rate as the dry time and temperature, and the measurement values of load cell appeared stable response characteristics through repeated experiments. Hereafter we judge that the reliability can be improved increasingly through the expansion of temperature-humidity range and the comparative analysis with CFD(Computational Fluid Dynamics) program.
