Application of herbal medicines as natural preservatives has been increased because of its low toxicity or side effect, compared to artificial preservatives. In this study, papers and patents researching anti-microbial activity of herbal medicine were collected and analyzed by the year of publishment, species of bacteria, fungi, or yeasts, and herbal medicines used. After early 2000's, the number of paper publishment has been decreased, while that of patent registration has been increased up to early 2010's. Most studied species were Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa, as gram-positive or gram-negative bacteria, and Candida albicans and Aspergillus niger as fungi. The bark of Cinnamomum cassia (L.) J. Presl was most frequently studies herbal medicine, followed by the roots of Scutellaria baicalensis Georgi and Sophora flavescens Ait. This study demonstrates that herbal medicines can be used as natural preservatives against diverse species of bacteria, fungi, or yeasts with their wide-ranged anti-microbial activities.

Overall, accuracy as a performance measure does not fully consider modular accuracy: the accuracy of classifying 1 (or true) as 1 is not same as classifying 0 (or false) as 0. A smarter classification algorithm would optimize the classification rules to match the modular accuracies' goals according to the nature of problem. Correspondingly, smarter algorithms must be both more generalized with respect to the nature of problems, and free from decretization, which may cause distortion of the real performance. Hence, in this paper, we propose a novel vertical boosting algorithm that improves modular accuracies. Rather than decretizing items, we use simple classifiers such as a regression model that accepts continuous data types. To improve the generalization, and to select a classification model that is well-suited to the nature of the problem domain, we developed a model selection algorithm with smartness. To show the soundness of the proposed method, we performed an experiment with a real-world application: predicting the intellectual properties of e-transaction technology, which had a 47,000+ record data set.

Control of food pathogens is critical in food safety field. Norovirus is one of the major causes of gastroenteritis and food poisoning worldwide, however, currently, there is not a vaccine or a specific drug available for its treatment. There are several methods to inactivate norovirus during food processing by chemical and physical treatments, however, the use of natural substance has been suggested as an optional strategy due to their safety and consumer preference. In this study supported by Ministry of Food and Drug Safety in Korea, we identified novel plant-derived substances with significant anti-norovirus activities. The aim of this project was to determine the antiviral activity of a wide range of natural substances, including plant-derived extracts and essential oils, using a norovirus surrogate system, human norovirus replicon-bearing cells, and mouse in vivo experiments. During the activity screening test, we identified novel anti-norovirus substances or oils using plaque assay with MNV-1. Six selected substances were formulated into an optimum mixture and used as an ingredient for salad sauce of which anti-novovirus activity was confirmed(pending for patent and paper submission). The potential application of selected natural substances as a metal surface sanitizer was also tested. Interestingly, the mixture of selected natural compounds showed a significant inhibitory effect against norovirus. These results suggest that these substances may be used as food ingredient with anti-norovirus antivity or components for surface sanitizers to prevent norovirus contamination.

In order to achieve carbon neutrality, it is necessary to commercialize and popularize carbon dioxide capture technology, so the purpose of this study is to put forward the design of public facilities suitable for public environment. In the design direction of public facilities for carbon capture and environmental purification, the application of carbon capture technology in air, the application of carbon capture and adsorption materials, and carbon reduction recycling are selected for development. In order to achieve carbon neutrality, this study develops a new concept of public facility design which is different from the existing public facilities in public space. From this point of view, it has great enlightenment significance. Public facilities adopting carbon-neutral technology are environmentally friendly public facilities that conform to the times, and can be installed in parks, roads and other spaces. With the rest of citizens and the role of communities, it is expected to contribute to popularization and activation.

Atopic dermatitis (AD) is a common skin disease in animals and several therapeutic trials with various drugs have been conducted for more effective management of AD. However, these trials have not been able to properly address all the aspects of AD management because of the lack of good efficacy or due to significant side effects of the drugs being tested. Synbio-glucan functional spray is a functional skin spray using Synbio-glucan composed of β-glucan and probiotics. We designed a functional spray composed of Synbio-glucan (patent application number:10-1805863), distilled water, glycerin, solubilizer, and 40% alcohol. We tested the efficacy and safety of the functional spray on six dogs with AD. The trial was conducted with the consent of the caregivers. The spray was applied to the skin lesions, including the trunk, axillae, inguinal region, or periocular areas, thrice a day for 30 days. To evaluate the efficacy of this functional spray, we assessed the pruritus visual analog scale (PVAS) and the canine atopic dermatitis extent and severity index (CADESI)-4. At the end of one month, the results clinical scores after functional spray treatment showed a significant decrease in the PVAS (p = 0.03) and CADESI-4 (p = 0.03) in all the subject dogs with AD. This study thus confirmed that the Synbio-glucan functional spray is efficacious and safe for the treatment of AD in dogs.

Because the USV(Unmanned Surface Vehicle) is capable of remote control or autonomous navigation at sea, it can secure the superiority of combat power while minimizing human losses in a future combat environment. To plan the technology for the development of USV, the trend analysis of related technology and the selection of promising technology should be preceded, but there has been little research in this area. The purpose of this paper was to measure and evaluate the technology trends quantitatively. For this purpose, this study analyzed the technology trends and selected promising/declining technologies using topic modeling of papers and patent data. As a result of topic modeling, promising technologies include control and navigation, verification/validation, autonomous level, mission module, and application technology, and declining technologies include underwater communication and image processing technology. This study also identified new technology areas that were not included in the existing technology classification, e.g., technology related to research and development of USV, artificial intelligence, launch/recovery, and operation, such as cooperation with manned and unmanned systems. The technology trends and new technology areas identified through this study may be used to derive key technologies related to the development of the USV and establish appropriate R&D policies.
