To estimate the benefit of high-resolution meteorological data for building energy estimation, a building energy analysis has been conducted over Busan metropolitan areas. The heating and cooling load has been calculated at seven observational sites by using temperature, wind and relative humidity data provided by WRF model combined with the inner building data produced by American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE). The building energy shows differences 2-3% in winter and 10-30% in summer depending on locations. This result implicates that high spatiotemporal resolution of meteorological model data is significantly important for building energy analysis.

In order to clarify the contribution rate of PM concentration due to regional emission distribution, Brute force analysis were carried out using numerical estimated PM data from WRF-CMAQ. The emission from Kyeongki region including Seoul metropolitan is the largest contribution of PM concentration than that from other regions except for emission of trans-country and source itself. Contribution rate of self emission is also the largest at Kyeongki region and its rate reach on over 95 %. And the rate at Gangwon region also higher than any region due to synoptic wind pattern. Due to synoptic wind direction at high PM episode, pollutants at downwind area along from west to east and from north to south tends to mix intensively and its composition is also complicated. Although the uncertainty of initial concentration of PM, the contribution of regional PM concentration tend to depend on the meteorological condition including intensity of synoptic and mesoscale wind and PM emission pattern over upwind region.

This study was carried out to investigate the effect, range of practice, and propriety for diagnosis of early non-pregnancies and reproductive disorders by dairy cows' milk progesterone analysis used EIA-kit of home products. The results were summarized as follows : 1. During 2 to 6 months after artificial insemination, the results of milk progesterone measurement by Home-kit and Auto ELISA reader-kit with pregnant dairy cows(152 heads) certified by rectal palpation were revealed, in Home-kit, 145 heads(95.4%) of positive reaction, 7 heads(4.6%) of quasi-positive, and 0 heads(0%) of negative among 152 heads and, in Auto ELISA reader-kit, 152 heads(100%) of positive reaction among 152 heads. 2. During 19 to 22 days after artificial insemination, the results of milk progesterone measurement by Home-kit, and thereafrer during 50 to 90 days after that, the results of pregnant test by rectal palpation were summarized as follows : 147 heads(82.1%) among 179 heads of positive reaction by Home-kit and 5 heads(31.3%) among 16 heads of quasi-positive were revealed pregnant cows by rectal palpation, and 42 heads(100%) among 42 heads of negative were non-pregnant. 3. During 19 to 22 days after artificial insemination, the results of milk progesterone measurement by Auto ELISA reader-kit, and thereafrer during 50 to 90 days after that, the results of pregnant test by rectal palpation were summarized as follows : 146 heads(86.9%) among 168 heads of positive reaction by Auto ELISA reader-kit and 6 heads(28.6%) among 21 heads of quasi-positive were revealed pregnant cows by rectal palpation, and 48 heads (100%) among 48 heads of negative were non-pregnant. 4. For the accuracy of the rectal palpation, Home-kit and Auto ELISA reader-kit were used in the cows of ovarian diseases. The results were following : in the cows of reproductive disorders expected negative milk progesterone, the accuracies of rectal palpation were the same 75.5%(40 heads among 53 heads) by Home-kit and Auto ELISA reader-kit, and in the cows of reproductive disorders expected positive milk progesterone, the accuracies of rectal palpation were 82.6%(19 heads among 23 heads) and 91.3%(21 heads among 23 heads) by Home-kit and Auto ELISA reader-kit, respectively, and the general accuracies of rectal palpation were 77.6%(59 heads among 76 heads) and 80.3%(61 heads among 76 heads) by Home-kit and Auto ELISA reader-kit, respectively.

All concrete structure in agricultural improvement project must satisfied durability, serviceability, safety. It is important for structure that satisfied these natures to good quality at design and construction step, and must continuous maintenance. Most of the concrete structures is construct at winter season, is contacted with water, has various type and sporadic in wide area. The objective of this study is to make the Concrete-Quality-Control diagram for agricultural infrastructure project using GIS. And, analyze the diagram with external factor(terrain, stream, economic etc.) to know the factor of concrete quality control.
