The purpose of this study was to determine the effects of coniferous essential oils (EOs) blended films on insect repellence and crop productivity. Low-density polyethylene (LDPE) film is widely used, especially in agriculture and for food packaging. Ethylene vinyl acetate was blended with LDPE to reduce volatilization of EOs. An EO from Japanese cypress (Chamaecyparis obtusa) was incorporated into the blend film to conduct field research on antimicrobial and insect repellent properties. Among the various concentrations of EO, the highest concentration (2.5%) showed the highest efficiency in terms of pesticidal activity. The ability to inhibit microbial growth can be explained by the lipophilic properties of the EO component, and many studies have already demonstrated this. Agricultural films containing all types of EO have been tested on various crops such as chili, cucumber, Korean melon and have been able to verify their effectiveness in avoiding pests and increasing yields. From these results, it was found that it is reasonable to use a modified film such as a composite film containing an EO for agriculture. Thus, the modified film containing EO has undoubtedly shown impressive potential for reducing the use of pesticides in a variety of ways, not only for agricultural mulching film but also for food and agricultural product packaging. This product is an environmentally friendly chemical and is safe for agricultural and industrial and food packaging applications, among others. In particular, the use of agricultural films significantly reduces the use of pesticides, suggesting that farmers can increase their incomes by reducing working hours and costs, and increasing production.

S100A8 and S100A9 are associated with myeloid cell differentiation, chemotactic activities, adhesion of neutrophils, and apoptosis. In this study, we investigated the contribution of S100A8 and S100A9 to differentiation of the human eosinophilic leukemia cell line, EoL-1. S100A8 and S100A9 increased the number of vacuole per one cell and the protein expression of EPO and MBP. Rottlerin, an inhibitor of protein kinase C delta ($PKC{\delta}$), inhibited the EoL-1 cell differentiation induced by S100A8 and S100A9. These results suggest that S100A8 and S100A9 may regulate the differentiation of eosinophilic progenitors. Moreover, these findings may shed light on elucidation of eosinophil differentiation due to S100 proteins.

Purpose of this research is estimation of water depth by hyperspectral remote sensing in area that access of ship is difficult. This research used EO-l Hyperion satellite imagery. Atmospheric and geometric correction is executed. Compress of band used MNF transforms. Diffuse Attenuation Coefficient of target area is decided in imagery for water depth estimation. Determination of Emdmember in pixel is using Linear Spectral Unmixing techniques. Water depth estimated using this result.

This study, multispectral and hyperspectral sensors were utilized to use radiometric cross validation for the purpose of radiometric quality evaluation of a 'KOMPSAT-3'. Images of EO-1 Hyperion and Landsat-8 OLI sensors taken in PICS site were used. 2 sections that have 2 different types of ground coverage respectively were selected as the site of cross validation based on aerial hyperspectral sensor and TOA Reflectance. As a result of comparison between the TOA reflectance figures of KOMPSAT-3, EO-1 Hyperion and CASI-1500, the difference was roughly 4%. It is considered that it satisfies the radiological quality standard when the difference of figure of reflectance in a comparison to the other satellites is found within 5%. The difference in Blue, Green, Red band was approximately 3% as a comparison result of TOA reflectance. However the figure was relatively low in NIR band in a comparison to Landsat-8. It is thought that the relatively low reflectance is because there is a difference of band passes in NIR band of 2 sensors and in a case of KOMPSAT-3 sensor, a section of 940nm, which shows the strong absorption through water vapor, is included in band pass resulting in comparatively low reflectance. To overcome these conditions, more detailed analysis with the application of rescale method as Spectral Bandwidth Adjustment Factor (SBAF) is required.

Korea Aerospace Research Institute (KARI) has been trying for utilizing the polar station in Svalbard, Norway to receive the KOMPSAT-2 images, which are distributed and applied directly for Europe Space Agency (ESA) users. Now, KARI is operating the SpaceCapture-2 system that provides the KOMPSAT-2 catalogue service via the internet, whereas ESA is operating the EOLI-SA tool that provides access to the online ESA catalogues of Earth Observation (EO) products. This paper describes external interface based on service-oriented architecture in order to provide the KOMPSAT-2 catalogue service from the SpaceCapture-2 system to the EOLI-SA tool. As the KOMPSAT-2 catalogue service is available in the EOLI-SA tool through an implementation of external interface, the extend use of KOMPSAT-2 imageries is expected.
