온실가스 배출량과 장래 저감 가능량의 산정은 기후변화협약 참여협상 및 저감대책 수립에 없어서는 안될 중요한 기초자료이다. 이를 위하여 본 연구에서는 환경부문(폐기물, 하폐수분야)의 온실가스 배출량을 추정하기 위한 배출계수와 관련 정책을 검토하고 이를 토대로 장래 온실가스 배출량을 예측하고 저감잠재량을 평가하고자 한다. (중략)

The relationship between source leaf position and photo-assimilate translocation and distribution was characterized for tomato (Lycopersicon esculentum Mill) grown in the greenhouse. Three different positions of source leaf on the stem (first node above or below the first fruit cluster and $5^{th}$ node above the first fruit cluster) were tested for their influence on $^{14}CO_2$ assimilation and transfer to different parts of the plant. The leaves at the $5^{th}$ node above the first fruit cluster transferred the highest (57%) proportion of $C^{14}$ to other plant parts, followed by leaves home on the first node below the first fruit cluster (50%), and the first node above the first fruit cluster (39%). In all treatments, fruits served as the strongest sink for $C^{14}$, followed by stem, leaf, and root tissues. The leaf home on the $5^{th}$ node above the first fruit cluster transferred the largest amount of $C^{14}$ to the second fruit cluster.

Recently, the internal combustion engines have focused on reducing both the CO2 emissions in order to cope with severe regulations for greenhouse effect. Therefore, various new technologies have been developed in many countries. Among them, the cooling system is spotlighted because it has great effect on fuel efficiency. However, the present engine cooling system is almost same as one of the 50 years ago. The needs for high performance and compact size make it important to improve engine cooling system, down-sizing and control method of coolant flow. Thus, low fuel consumption technology such as control and synthetic management of cooling system was necessary to satisfy with these needs. In this study, we applied electric thermostat to improve the fuel economy. The fuel consumption was compared after driving FTP-75 mode on both conditions which were with a conventional wax thermostat and with a electric thermostat. The coolant temperature of opening the electric thermostat is higher.

Biocontrol is playing a more and more important role in plant disease management. Evidences show that there are optimum prospects for people to apply biocontrol approach to control plant disease or to study the mechanism of antagonism.“The study of Antagonistic Protein of Bacillus spp.to Xanthomonas oryzae pv. oryzae”has been worked in our laboratory since 1986. One hundred and thirty antagonistics bacteria were screened out, most of them belonged to Bacillus spp., and showed very strong inhibitive effect to various plant pathogens. Nine antagonistic proteins (peptides) were purified (P11-I, P11-II, B8, B826-I, B826-II, A30-I, A30-II, G35). Two antagonistic protein related DNA fragments (B826-I, A30-II) were cloned and sequenced. B826-I DNA fragment composed by 905 bp, and it contained two ORF encoding 95, and 54 amino acids, respectively. By using Rifr and Kamr as the selective markers, we found the bacteria could colonize on rice leaf for at least 40 days. In greenhouse the antagonistic bacteria showed certain degree of control efficiency.

The objective of the study is to examine the relationship between water resources, energy demand, food production, and environmental pollutants in selected SAARC nations, namely, Bangladesh, India, Pakistan, and Sri Lanka, during the period of 1990-2016. The results show that water, energy, and food (WEF) resources substantially affected air quality in the form of high mass carbon emissions, fossil fuel energy demand, methane discharges, nitrous oxide emissions, and greenhouse gas emissions in these countries. Food production and food deficit largely increase $CO_2$ emissions due to unsustainable production and malnutrition, while land use under cereal production increases $CH_4$ and $N_2O$ emissions. Electricity production escalates $CO_2$ emissions and fossil emissions across countries. The results support the carbon EKC hypothesis, while monotonic increasing function exists in case of fossil fuel energy. The study emphasizes the need to ensure environmental sustainability agenda by adopting cleaner production technologies in WEF resources.

Truffles are cultivated by growing seedlings of compatible tree species in pasteurized substrate amended with truffle spores, maintaining the inoculated seedlings in the greenhouse until the mycorrhizal relationship is established and certified, planting the infected seedlings onto appropriate and properly prepared sites, and managing the resulting truffieres (truffle orchards) to maintain the truffle infections and encourage truffle fruiting. Questions remain to be addressed at each step of the process in developing best management practices for truffle cultivation.

As the introduction of new climate system, efforts to change carbon neutrality, efforts to convert carbon neutrality. In Korea, we are setting up carbon emissions through greenhouse gas and energy target management system for business and companies that emit carbon emissions. The construction industry quantitatively predict the carbon emissions, but it is struggling to set up the amount of carbon emissions before construction stage, but it is suffering from lack of data. Therefore, this study was conducted by collecting data on the energy usage amount of carbon emissions according to the energy usage of the construction phenomenon and low-capacity prediction of the construction phenomenon. Through collected data, the average energy usage amount by building users and evaluated the average carbon emissions. It also evaluated the contribution of carbon emissions by energy sources.

This study was carried out to investigate planting density suitable for technology that can produce a lot of small seed potatoes to machine sowing, the test material was made of less than 3 g of seed potatoes, and planting density was 75×10, 75×15, 75×20cm. the results of the test study were as follows, number of potatoes per 10a and number of potatoes under 50 g were the most 75×10cm in 2sowing methods. In view of these results, planting density suitable for technology that can produce a lot of small seed potatoes to machine sowing is judged 75×10cm in 2sowing methods. In order for this study to be applied in the agricultural field, cultivation management such as adequate water supply will be required.
