林韻 ( Lin¸ Yun ) 한국일어교육학회 2021 일본어교육연구 Vol.- No.56

本研究では、第二言語(以下、L2)としての日本語の文章聴解における空間的状況モデルの構築において、視空間作動記憶の働き方が学習者の言語性作動記憶容量の大小によって異なるか否かを検討することを目的に、母語(以下、L1)聴解を対象とした実験1とL2聴解を対象とした実験2を行った。実験では、言語性作動記憶容量を個人差要因として扱い、二重課題として空間的タッピング課題を用い、その種類を中央制御部の関与の大きさによって操作した。具体的には、単純タッピング条件、複雑タッピング条件及びタッピング無し条件を設けた。実験の結果、2つの実験ともに、言語性WM容量が大きい聴き手のほうが、それが小さい聴き手より地図作成テストにおける正再生率が高く、言語性WMがL1とL2の聴解における空間的状況モデルの構築において重要な役割を果たすことが示唆された。また、空間的タッピング課題による妨害の出方が、言語性WM容量の大小によって異なった。聴き手の言語処理の自動性、また、言語理解の効率性の高低によって、視空間WMの働き方が異なり、空間的状況モデルを構成する意味表象のモダリティによる豊富さが異なることが明らかになった。 The purpose of the present study is to investigate how visuospatial working memory (visuospatial WM) is involved in the construction of a spatial situation model for spatial passages presented auditorily in Japanese, L2. 2 experiments were conducted to compare between L1and L2 listening comprehension. In the experiments verbal working memory (verbal WM) capacity was manipulated as an independent variable and a spatial tapping task was used as a dual task, which consisted of simple tapping conditions, complex tapping conditions as a target-tracking task, and control conditions, manipulated by the degree of involvement of central executive. As a result in both experiments the listeners with high verbal WM capacity had a higher correct recall rate in the mapping drawing test than the listeners with low verbal WMcapacity, which suggests that verbal WM plays an important role in the construction of spatial situation models in both L1 and L2 listening comprehension. In addition, the interference caused by the spatial tapping tasks differed depending on the verbal WM capacity. These results indicate that depending on the listener's automaticity of language processing and the efficiency of language comprehension the degree of the involvement of visuospatial WM differed and consequently, the richness of the representations that make up the spatial situation model differed by modality.

Cation exchange resins (CERs) are widely applied to purify waste liquids generated during the operationof nuclear reactors. The radioactive nuclides 60Co and 58Co are important corrosion activation products inreactor cooling water. In this study, the simulated Co doped CERs were oxidized with ternary carbonate. According to the thermogravimetric analysis (TG), the decomposition of Co doped CERs includes threeprocesses: 1. Elimination of the osmotic water; 2. Pyrolysis of sulfonic acid group; 3. Destruction of styrene–divinylbenzene copolymer. The X-Ray Diffraction (XRD) patterns indicate that sulfur mainly exists inthe form of sulfate in waste salt. The Co2+ undergoes the path of CoS2 ? Co3O4 with the increase of temperatureand the transition point is 650 C. Combined with Fourier Transform Infrared Spectrometer (FTIR)spectra and X-ray Photoelectron Spectroscopy (XPS) analysis, sulfonic acid groups begin to decomposeat 350 C. During the molten salt oxidation process, most of the sulfur in sulfonic acid groups is entrappedby carbonate as the form of sulfate, and a little of which remains as sulfone group, sulfoxide group andsulfur bridge in residue. When the resins are oxidized at 800 C, the retention rate of Co2+ is 97.3%, indicatingthat the molten salt oxidation can effectively remain Co2+ and convert it into a more stablesubstance.

<P>Scrotal hyperthermia leads to oxidative stress and apoptosis in spermatogenic cells, which subsequently causes male infertility. In this study, we examined the effects of <I>β</I>-carotene and/or curcumin on heat-stress- (HS-) induced testicular injuries in mice. ICR male mice (8 weeks old) were consecutively treated with <I>β</I>-carotene (10 mg/kg) and/or curcumin (20 mg/kg) orally once a day for 14 days and then subjected to single exposure with scrotal HS at 43°C for 15 min on day 7. HS induced a significant reduction in testicular weight, appearance of multinucleated giant cells, and desquamation of germ cells in destructive seminiferous tubules, as well as degenerative Leydig cells. Moreover, HS reduced the superoxide dismutase (SOD) activity and mRNA levels of mitochondrial SOD, phospholipid hydroperoxide glutathione peroxidase, B-cell lymphoma-extra-large, and 3<I>β</I>-hydroxysteroid dehydrogenase, with increases in lipid peroxidation levels and mRNA levels of BCL2-associated X protein and caspase-3 relative to those of the control group. However, these changes were significantly recovered by combined treatment with <I>β</I>-carotene and curcumin after HS. These findings indicate that the combined treatment with <I>β</I>-carotene and curcumin might be a valuable protective agent to ameliorate hyperthermic spermatogenic disorders via its potent antioxidative, antiapoptotic, and androgen synthetic effects.</P>

Although hyaluronic acid (HA) has been developed as a nanoparticle (NP; 320-400 nm) for a drug delivery system, the tissue targeting efficacy and the pharmacokinetics of HA-NPs are not yet fully understood. After a dose of 5 mg/kg of cyanine 5.5-labeled HA-NPs or HA-polymers was intravenously administrated into mice, the fluorescence was measured from 0.5 h to 28 days. The HA-NPs fluorescence was generally stronger than that of HA-polymers, which was maintained at a high level over 7 days in vivo, after which it gradually decreased. Upon ex vivo imaging, liver, spleen, kidney, lung, testis and sublingual gland fluorescences were much higher than that of other organs. The fluorescence of HA-NPs in the liver, spleen and kidney was highest at 30 min, where it was generally maintained until 4 h, while it drastically decreased at 1 day. However, the fluorescence in the liver and spleen increased sharply at 7 days relative to 3 days, then decreased drastically at 14 days. Conversely, the fluorescence of HA-polymers in the lymph node was higher than that of HA-NPs. The results presented herein may have important clinical implications regarding the safety of as self-assembled HA-NPs, which can be widely used in biomedical applications.

Yun Lin,Can Wang,Chunguang Ma,Zheng Dou,Zhiqiang Wu,Zhiping Zhang 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.2

Information entropy features are often used for radiation source signal recognition, but due to the information entropy is very sensitive to noise, so this method has greater recognition rate changes with the SNR. This paper putting forward a viable recognition based on Entropy and cloud model. using cloud model to extract secondary features of signals, build radiation source signal’s entropy and cloud feature vector. The method uses cloud model description and processing interval fuzzy and observation noise data, better solve the low SNR cases of radiation source signal feature extraction problem. At the same time, putting forward the similar cloud classification recognition algorithm based on cloud model. The simulation results show that Entropy and cloud model has better recognition effect under low SNR, which can improve the signals’ recognition rate under low SNR.

Original Article: Biochemistry/Molecular Biology : Various Pathogenic Pseudomonas Strains that Cause Brown Blotch Disease in Cultivated Mushrooms

Brown blotch disease in cultivated mushrooms is caused by Pseudomonas tolaasii, which secretes a lipodepsipeptide, tolaasin. Tolaasin is a pore-forming toxin in the cell membranes, thus destroying the fruiting body structure of mushroom. In this study, we isolated pathogenic bacteria from mushrooms that had symptoms of brown blotch disease. In order to identify these bacteria, their 16S rRNA genes were sequenced and analyzed. Pathogenic bacteria identified as Pseudomonas species were thirty five and classified into five subgroups: P1 to P5. Each subgroup showed different metabolic profile measured by API 20NE kit. Fifty percent of the bacteria were identified as P. tolaasii (P1 subgroup). All five subgroups caused the formation of brown blotches on mushroom tissues and the optimum temperature was 25oC, indicating that they may be able to secrete causal factors, such as tolaasin and similar peptide toxins. These results show that there are at least five different pathogenic Pseudomonas species as blotch-causing bacteria and, therefore, strains from the P2 to P5 subgroups should be also considered and studied as pathogens in order to improve the quality and yield of mushroom production.
