We present a processing system for the Atmospheric Infrared Sounder (AIRS) sounding suite onboard Aqua satellite. With its unprecedented 2378 channels in IR bands, AIRS aims at achieving the sounding accuracy of radiosonde (1 K in 1-km layer for temperature and $10\%$ in 2-km layer for humidity). The core of the processor is the International MODIS/AIRS Processing Package (IMAPP) that performs the geometric and radiometric correction for generation of Level 1 brightness temperature and Level 2 geophysical parameters retrieval. The processor can produce automatically from received raw data to Level 2 geophysical parameters. As we process the direct-broadcast data almost for the first time among the AIRS direct-broadcast community, a special attention is paid to understand and verify the Level 2 products. This processor includes sub-systems, that is, the near real time validation system which made the comparison results with in-situ measurement data, and standard digital information system which carry out the data format conversion into GRIdded Binary II (GRIB II) standard format to promote active data communication between meteorological societies. This processing system is planned to encourage the application of geophysical parameters observed by AIRS to research the aqua cycle in the Korean peninsula.

As influence of the 4th industry is growing with development of information society more electronic devices and sensor are used in the field. As this is the case, importance of signal processing during data transfer is rising Furthermore, the need for technology to remove noise caused by various reasons and to stabilize sensor output is growing as well. This research suggests digital filter algorithm that efficiently remove noise by stabilizing output of accelerating sensor. The standard value of this algorithm is calculated by applying Gaussian coefficient. To maintain its feature, final output is obtained by subtracting weight depending on variance from standard value For its evaluation, it is compared with other protocols and its function is checked through output features.

Purpose: This study investigated the quality characteristics of traditional and commercial red pepper pastes (Gochujang) for development of traditional red pepper pastes. Methods: Proximate compositions, amino acid nitrogen contents, salt contents, color, viable bacteria, and inorganic substance contents of 19 traditional and three commercial Gochujang were investigated. Results: Analysis of proximate compositions showed huge differences between the samples. For moisture content, six kinds of traditional Gochujang did not meet the standard of the food codex. Contents of moisture, fat, and protein were significantly higher in traditional than commercial Gochujang. However, carbohydrate content was higher in commercial than traditional Gochujang, and thus calories were also higher. The amino nitrogen contents of the three kinds of traditional Gochujang did not meet the standard of the food codex. Salt contents and color were not significantly different between traditional and commercial Gochujang. In the microbiological analysis, total bacteria counts were higher in traditional than commercial Gochujang. The number of B. cereus did not exceed the standard of the food codex in all samples. S. aureus and fungi were not detected in any samples. In the inorganic substance analysis, inorganic substances contents in Gochujang were in the order of Na, K, Mg, and Ca. Overall, Na, K, Mg, and Ca were more abundant in traditional than commercial Gochujang. However, due to wide variations in inorganic substance contents of traditional Gochujang, there were no significant differences between traditional and commercial Gochujang. Conclusion: For the development of traditional Gochujang, quality standardization is considered necessary.

Through the 4th Industrial Revolution, various digital equipments are being distributed, and accordingly, the importance of data processing is increasing. As data processing has a great effect on the reliability of equipment, its importance is increasing, and various studies are being conducted. In this paper, we propose an algorithm to remove AWGN in consideration of the noise in the image. The proposed algorithm is used in the filtering process by inferring the standard deviation of the image noise. The noise is removed by dividing the filter for the high frequency component and the filter for the low frequency component compared with the standard deviation of the filtering mask. The proposed algorithm is simulated with the existing methods for evaluation and compared and analyzed by difference image, PSNR and profile. The proposed algorithm minimizes the effect of noise and preserves the important characteristics of the image and shows the performance of efficient noise removal.

While herbal medicine including mineral herbal medicine mostly provides microelements to the human body thanks to abundant metallic elements, its harmfulness has been raised due to elements of heavy metals. Harmfulness of mineral herbal medicine needs to be analyzed quantitatively as well as qualitatively so that specificity of herbal medicine including mineral herbal medicine can be reflected. Consequently, the following aims should be set up to mineral herbal medicine, REALGAR, standard processing of REALGAR and the standards of processed drugs should be secured. On the basis of the results of this study, the reasonable measures to develop the processing method and the test method for heavy metals were presented. Such measures are expected to give the following results. First, consumers may take food and medicine without anxiety, and food and medicine may be effectively managed, and the national service may be improved, and also safety against heavy metals may be publicized. Second, as the principal ingredients and microelements of mineral herbal medicine are qualitatively analyzed, such results are expected to contribute to the advance of national analytics for herbal medicine.

High-resolution satellite image processing software should be able to ensure accurate, fast, compact data processing in offline or online environment. In this paper, component software for high-resolution satellite image processing is developed using OpenGIS components and real-time data processing architecture. The developed component software is composed of three major packages, which are data provide package, user interface package, and fast data processing package. The data provider package encodes and decodes diverse image/vector data formats and give identical data access methods to developers. The user interface package supports menus, toolbars, dialogs, and events to use easier. The fast data processing package follows the OpenGIS's data processing standards, which can deal with several processors as components with standard procedural functionalities.

Drop size is one of the most important parameters which are control the performance of the engine using liquid fuel/oxidizer and drop formation is mainly controlled by aerodynamic force caused by ambient gas. Because of this, empirical data and correlation acquired under standard ambient condition are not valid. So experiments under high ambient pressure condition to measure the drop size using image processing method And find the empirical correlation between SMD and chamber pressure(density), injection velocity.

In order to analyze big data, documents should be converted to a open standard format to increase machine readability. It also need natural language processing tools. This study focused on the background of intelligent document processing and the status of research in the public sector, and predicted the changes in work that intelligent document processing would bring. This study noted the changes that intelligent document processing would bring to the archival work, and also considered changes in the role of archivist and their required competencies. Changes in archival work could be anticipated across a wide range of Records Management work and Archives Management work. In particular, it was expected to have a significant impact on the automation of repetitive archival tasks or the description and utilization of records. This study proposed the need to prepare new archival work procedures, methods, and necessary competencies in response to these change in archival work.
