This study was conducted to collect the patents of microbiome-based treatment technology for pets. An electronic search for microbiome or probiotics in brain nervous system disease was studied using the WINTELIPS database. Patent Cooperation Treaty of Korea, Japan, the EU, the US, and China that were registered by October 31, 2022 were selected in this study. A total of 206 patents were included for final analysis. Since 2016, patent activity has shown an explosive increase in recent years. China is the leading market in this technology field, and Korea has the second-highest market share. To provide the groundwork for the next research and development, we examined the industrial trend of microbiome for brain nervous system diseases in this study using an analysis of patents that have been applied for and registered up to this point. Looking at the overall patent trends by year in the technology field related to treating of brain and nervous system diseases using the microbiome, there was a tendency to repeat increasing and decreasing trends. However, considering 2021 and 2022, which have undisclosed sections, it can be seen that patent activity has tended to increase explosively in recent years, starting in 2016. If related studies use the patent analysis data constructed in this way strategically, it is expected that it will lead to patent registration and the development of new products, ultimately contributing to the revitalization of the companion animal industry.

The purpose of this study is to use the hybrid steam-solvent process, because it is created in the form of water, bitumen, and water/bitumen emulsion by hot steam, so effective separation is required. Methods for separating the emulsion include a chemical separation method by adding a chemical, a separation method using an electrostatic property, a separation method using a membrane, a separation method using a microwave, and the like. Among them, the most used method is the separation method using a chemical, and it is reported that the separation efficiency of the emulsion is the best. In this study, a method for efficiently separating bitumen emulsions using a chemical separation method adding an emulsifier was investigated. In particular, technological trends in oil sand oil treatment technology were analyzed based on patent analysis.

아산화질소(Nitrous oxide, N2O)는 지구온난화 물질의 하나로 이산화탄소에 비해 지구온난화효과가 310배 강하고 분해하는데 120년이 소요되기 때문에 오존층 파괴에 주범으로 알려져 있다. 따라서 본 연구에서는 N2O를 저감하기 위해 고온 열분해 기술을 적용하여 N2O 저감 공정에서 발생하는 NOx 배출 특성에 대해 조사하였다. 고온 유동장을 형성하기 위해 동축 분젠 예혼합 화염을 열원으로 채택하였으며 실험 변수로는 노즐출구속도, 동축류 속도 및 N2O 희석률로 설정하였다. 실험 결과, NO 생성률은 노즐출구속도 및 동축류 유량에 관계없이 N2O 희석률이 증가함에 따라 증가하였다. NO2의 경우에는 연소 불안정성(Kelvin Helmholtz 불안정)이 억제된 안정된 예혼합 화염에서 다량으로 배출되었는데, 이는 화염 면 부근에서 감소된 N2O의 체류시간으로 인해 열분해 시간이 충분하지 않기 때문인 것으로 사료 된다. 따라서 N2O의 저감 효율을 증진시키기 위해서는 K-H 불안정성이 발생되는 노즐출구속도를 선정하여 화염 면 부근에서 발생되는 와류(toroidal vortex) 형태의 유동 구조를 형성하는 것이 N2O의 체류시간을 증가시키는데 효과적인 것으로 판단된다.

수처리 분리막 분야에서 고분자는 세라믹과 함께 가장 중요한 소재로 이용되고 있다. 본 총설에서는 이러한 고분자 분리막 소재의 기술동향을 상용화 제품을 중심으로 분석하고자 하였으며, 이를 위하여 수처리 분리막의 종류에 따라 MF (Microfiltration), UF (Ultrafiltration), NF (Nanofiltration)/RO (Reverse Osmosis) 분리막으로 구분하여, 국가별, 소재별, 회사 별 고분자 분리막 제품 동향을 살펴보았다. 이를 통하여, 각 분리막 종류별로 주로 사용되고 있는 소재의 종류를 파악할 수 있었으며, 동시에 시장 지배적인 위치에 있는 업체들을 파악하고 이들 업체들이 어떤 소재들로 제품 포트폴리오를 구성하고 있는지 분석할 수 있었다. 이러한 결과들을 바탕으로 각각의 분리막 종류에 따른 소재 시장의 특징을 제시하였으며, 이런 특징을 바탕으로 각 시장에 신규로 진입하기 위한 기술 개발 전략을 제안하였다.

CO2 separation technology for carbon capture, which is one of the hot issues to reduce greenhouse gases from industrial flue gas, has been intensively investigated so far. Despite of several benefits, the membrane technology has some obstacles like large-scale module fabrication, membrane durability, need of pre-treatment or high pressure drive for its industrial application. Also, the power plant flue gas with normally 10~20% of CO2 content should be concentrated upto 99% for being compressed and liquefied to transportable CO2 by pipeline, indicating the need of high selective membrane process as well as high recovery. In this work, the possibility of membrane process for post-combustion treatment in terms of recent technology will be announced. The practically applicable process for CO2 capture also be suggested briefly.

CCS is not a recent issue. Efforts to reduce carbon dioxide since the 1990s have been around the world, and the carbon dioxide emitted from post-combustion flue-gases is still enormous. Membrane technology also has been widely considered as a good candidate to enrichment of CO2, but it has not been verified about the remarkable advantages compare to the other technologies; such as amine scrubbing or physical adsorption. Numerous membranes for CO2 separation with high selectivity and permeance have been developed, but the membrane process for those applications are much less. The industrial technology to concentrate and store the carbon source has not been proved enough for its massive emission and engineering issue. Moreover, membrane technology lacks database for large scale processes. In this talk, the membrane process for CCS industry will be introduced. The considerable factors for industrial application of membrane technology will be also announced.
