  • 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.

  • It is a complex project to construct the standard system of sports events. Sports events standard system covers from the implementation plan to the evaluation work after the smooth implementation of sports events, involving many links. Large-scale sports events have extremely high media value. However, the successful organization and operation of large-scale sports events face many problems to be overcome, especially in terms of event safety. Although the organizers and organizers of large-scale events have invested many resources for the safe holding of sports events, violence similar to "football hooligans" in Europe is endless. At present, compared with Western countries, the standardization of sports events in China is low, and there is a problem of a late start and huge difference with Western developed countries. Knowing the construction of the standardization system's situation in China, we have summarized the data related to 15 sports events held in Chengdu is the last 5 years. By analyzing the problems in the process of holding these 15 events and the reflections of participants on the experience of sports events, the problems in the development of the standard system of sports events are discussed in depth. The final conclusion is that the system structure of China's sports events is not so good and athletes have a poor experience. China's sports event system still has many problems. Finally, we built a sports event standardization model using Internet of Things, and after a practical test we found that it has a good effect. Finally, we combined the current situation of sports event standardization system in China and put forward the following suggestions: laws and regulations related to the standard system of sports events must be formulated at the national level. The implementation level must strengthen the degree of integration of sports events and technology. To improve the quality of human resources in the management of sports events. The article puts forward targeted solutions, which play a great role in promoting the perfection and completeness of China's standard system for sports events. At the same time, it also promotes economic development and improves China's international status.

  • 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.
