본 연구에서는 여단급 과학화전투훈련 체계의 경제적 효과를 2가지 측면에서 분석하였다. 첫째, 2010년부터 2018년까지 대대급에서 여단급으로 확장된 과학화전투훈련 전력화사업에 대한 경제적 파급효과를 산업연관분석을 통해 생산유발 효과, 부가가치유발 효과, 고용유발 효과로 분석하였다. 둘째, 여단급 과학화전투훈련을 통한 예산 절감효과 분석을 위해 여단급 과학화전투훈련에 투입된 비용과 실탄을 사용하는 여단급 실기동 훈련의 투입된 비용 간 비용분석을 실시하였다. 연구결과 여단급 과학화전투훈련 전력화사업 간 4,449억원이 투입되어 생산유발 효과 6,883억원, 부가가치 유발 효과 4,777억원, 고용유발 효과는 4,795명인 것으로 분석되었다. 또한, 전력화사업 이후 여단급 과학화전투훈련을 통한 예산 절감효과는 1회 훈련기준 약 230억원이 절감되는 것으로 분석되었다. 본 연구를 통해 향후 육군에서 지속적으로 추진하고 있는 과학화훈련 관련 사업에 대한 타당성 확보 및 대외홍보를 위한 자로 활용할 수 있는 객관적 자료를 제시하였다. This study analyzed the economic effects of the KCTC System force integration project expanded from the battalion level to the brigade level from 2010 to 2018 in two aspects. First, using the input-output table issued by the Bank of Korea, the input-output analysis method, which analyzes the linkage structure and ripple effect between industries, was used to generate production inducement and the added value and employment inducement were analyzed. Second, as of 2020, the budget reduction effect of KCTC on a one-time basis was examined through a comparative analysis between the cost of a brigade-level actual maneuvering training using live ammunition and the cost of KCTC training of the same scale. The budget saved by one-time brigade-level KCTC training was approximately 23 billion won. The economic ripple effect was 688.3 billion won in production inducement, 477 billion won in value-added inducement, and 4,795 people in employment inducement effects. Finally, the analysis results derived through this study presented objective data that can be used as data for securing the validity of the science-related training projects that the Army is continuing to promote in the future and for public relations.

This study surveyed the vascular flora present in abandoned paddy field type of 237 forest wetlands in Korea to provide baseline data for conservation, management, and monitoring and to support preparation for damage and climate change. The study period was from April 2015 to November 2021. The vascular flora of 237 forest wetlands by abandoned paddy field type were identified to consist of 128 families, 510 genera, 1,022 species, 27 subspecies, 87 varieties, 10 forma, and 1,146 taxa. 4 taxa were identified as grade II endangered wild plants, 185 taxa were identified as northern lineage plants of the Korean Peninsula, 43 taxa were endemic to the Korean Peninsula, and 58 taxa were rare plants as designated by the Korea Forest Service. Further, 296 taxa were floristic target plants and there were 86 taxa of invasive alien plants. According to wetland preference, 79 taxa (6.9%) were obligate wetland plants, 103 taxa (9.0%) were facultative wetland plants, and 61 (5.3%) taxa were facultative plants. Additionally, 66 taxa (5.8%) were facultative upland plants, and 837 taxa (73.0%) were obligate upland plants.

Kang, Kui Hyun,Yun, Jong Sun,Ryu, Hwa Won 한국미생물 · 생명공학회 2000 Journal of microbiology and biotechnology Vol.10 No.1

Bioconversion of fumarate to succinate was anaerobically conducted in a synthetic medium containing glycerol as a hydrogen donor and fumarate as a hydrogen acceptor. We investigated the effects of pH, carbon and nitrogen sources, conversion substrate, and other culture conditions on the production of succinate using a newly isolated Enterococcus faecalis RKY1. Addition of a variety of carbonates to the medium significantly increased the rates of production of succinate. The production of succinate and cell growth were relatively satisfactory in the pH range of 7.0-7.6. By using glycerol as a hydrogen donor, high purity succinate was produced with few byproducts. Yeast extract as a sole nitrogen source was the most effective for producing succinate. As a result, the optimum condition of bioconversion was obtained at a medium containing 20g/l glycerol, 50g/l fumarate, 15g/l yeast extract, 10g/l K_2HPO_4 1g/l NaCl, 50 ppm MgCl_2, .6H_2O, 10ppm FeSO_4, . 7H_2O, and 5g/l Na_2CO_3 at pH 7.0-7.6. Under the optimum condition, a succinate concentration of 153g/l was produced in 36h. The total volumetric production rate and the molar yield of succinate were 4.3g/l/h and 85%, respectively.

Purification and Characterization of Mitochondrial Mg2+-Independent Sphingomyelinase from Rat Brain

Jong Min Choi,Yongwei Piao,Kyong Hoon Ahn,Seok Kyun Kim,Jong Hoon Won,Jae Hong Lee,Ji Min Jang,In Chul Shin,Zhicheng Fu,Sung Yun Jung,정의만,김대경 한국분자세포생물학회 2023 Molecules and cells Vol.46 No.9

Sphingomyelinase (SMase) catalyzes ceramide production from sphingomyelin. Ceramides are critical in cellular responses such as apoptosis. They enhance mitochondrial outer membrane permeabilization (MOMP) through self-assembly in the mitochondrial outer membrane to form channels that release cytochrome c from intermembrane space (IMS) into the cytosol, triggering caspase-9 activation. However, the SMase involved in MOMP is yet to be identified. Here, we identified a mitochondrial Mg2+-independent SMase (mt-iSMase) from rat brain, which was purified 6,130-fold using a Percoll gradient, pulled down with biotinylated sphingomyelin, and subjected to Mono Q anion exchange. A single peak of mt-iSMase activity was eluted at a molecular mass of approximately 65 kDa using Superose 6 gel filtration. The purified enzyme showed optimal activity at pH of 6.5 and was inhibited by dithiothreitol and Mg2+, Mn2+, N2+, Cu2+, Zn2+, Fe2+, and Fe3+ ions. It was also inhibited by GW4869, which is a non-competitive inhibitor of Mg2+-dependent neutral SMase 2 (encoded by SMPD3), that protects against cytochrome c release-mediated cell death. Subfractionation experiments showed that mt-iSMase localizes in the IMS of the mitochondria, implying that mt-iSMase may play a critical role in generating ceramides for MOMP, cytochrome c release, and apoptosis. These data suggest that the purified enzyme in this study is a novel SMase.

Yun-Sang Choi,Jong-Dae Park,Jung-Min Sung,Hae-Won Jang,Tae-Kyung Kim,Hyun-Wook Choi 한국산업식품공학회 2019 산업 식품공학 Vol.23 No.2

Korean sliced rice cakes, or tteokguk, are conventionally dried and rehydrated during their preparation. In this study, the effects of the perforation process and various drying methods (e.g., hot-air drying, vacuum drying, low temperature drying, and freeze drying) on the quality characteristics of tteokguk (rice cake soup) were evaluated. In the experiment, the rehydration capacity and lightness increased as the pore number increased. The hardness, redness, and yellowness of tteokguk, in contrast, tended to decrease as perforations increased. The texture, taste, and overall acceptability scores of tteokguk increased as perforations increased. With respect to drying methods, the rehydration capacity was greatest for vacuum drying. The hardness of tteokguk was lowest for vacuum drying. The redness, yellowness, pH, and sensory characteristics did not differ significantly among tteokguk samples treated through various drying methods. These results suggest that high-quality ready-to-eat Korean sliced rice cakes could be created by perforation and vacuum drying.

Background: Entecavir induces biochemical and histologic improvement of the liver in patients with chronic hepatitis B. This study aimed to clarify whether entecavir improves liver function in patients with hepatitis B virus (HBV) associated liver cirrhosis during 2 years treatment. Methods: A total of 356 patients who have HBV associated cirrhosis were treated with entecavir. Among them, 89 patients who are treated for at least 2 years and had no occurrence of hepatocellualr carcinoma, were enrolled retrospectively. A diagnosis of cirrhosis was based on image and/or endoscopic findings. Laboratory findings, model for end stage liver disease (MELD) score, Child-Pugh score, and AST platelet ratio index (APRI) score were compared between the initial and after 2 years entecavir treatment. Results: The mean age was 52±9 years old and number of male patients was 53 (59.6%). The mean AST and ALT were 117± 80 IU/L and 118±88 IU/L, respectively. The number of HBeAg positivity was 39 (43.8%) and mean HBV DNA level was 6.7±1.6 log10 copies/mL. After 2 years entecavir treatment, the rate of ALT normalization was 79.8%, undetectable HBV DNA was 91% (by real-time polymerase chain reaction), and HBeAg loss in HBeAg positive-patient was 71.8%. The improvement of total bilirubin level, albumin level, INR, platelet count, MELD score, Child-Pugh score, APRI score between the two time points was from 2.2±3.5 to 1.2±0.7 mg/dL (p=0.006), 3.7±0.6 to 4.0±0.6 g/dL (p<0.001), 1.4±0.4 to 1.2±0.2 (p<0.001), 110±48 to 121±58 ×103/mm3 (p=0.016), 11.9±4.7 to 9.5±3.4 (p<0.001), 6.3±1.9 to 5.5±1.3 (p<0.001), and 3.2±2.3 to 1.0±0.9 (p<0.001), respectively. Conclusions: Entecavir improves not only liver function but also fibrosis score in patients with HBV associated liver cirrhosis for long-term treatment.
