中國地域廣袤,方言種類繁多,但是,信息科技飛速發展的今天,方言正在悄然流逝,人們 對地方方言和傳統文化漸漸漠視和遺忘,方言的喪失必將導致傳統文化的失根,所以對方言的重視 和保護很重要。作為一名語言文化研究愛好者,希望通過研究比較更多的方言來讓人們更了解自己 的語言。方言作為母語,在我們學習第二語言的時候會直接影響到第二語言的習得,不僅存在積極 的促進作用,也存在消極的阻礙作用,這就需要我們對兩種語言進行深刻的了解和多方面的比較研究。蘇州和合肥分別歸屬於吳語區和江淮官話區,雖然是兩種方言,但是從地理位置上看,相互接連,可見兩種方言之間一定存在一些共同特點和差別。筆者就蘇州和合肥的語言上進行比較研究,選擇展現入聲字的中古音在兩地的今讀,分別從方言的聲母和韻母的對比進行分析和解說,以此來 找出兩種方言之間的差異。 However, with the rapid development of information technology, dialects are slipping away. People are gradually ignoring and forgetting local dialects and traditional culture. The loss of dialects will surely lead to the loss of traditional culture. As a language and culture research enthusiast, I hope to make people know more about their own language by studying and comparing more dialects. As the mother tongue, dialect will directly affect the acquisition of the second language when we learn the second language, which not only has a positive role in promoting, but also has a negative role in hindering, which requires us to have a deep understanding of the two languages and a comprehensive comparative study. Suzhou and Hefei belong to the wu-speaking area and the jianghuai guanhua area respectively. Although they are two dialects, they are connected with each other from the geographical position. It can be seen that there must be some common characteristics and differences between the two dialects. Based on a comparative study of the languages of Suzhou and Hefei, the author chooses to present the modern pronunciation of the Chinese ancient pronunciation of rusheng characters in the two places, and analyzes and explains the differences between the initial and final vowels of the dialects respectively, so as to find out the differences between the two dialects.

補强砂의 變形에 대한 硏究

禹文楨,金埈榮 嶺南大學校 工業技術硏究所 1989 연구보고 Vol.17 No.2

To understand the behaviour of the reinforced sand an experimental study has been conducted using the modified direct shear box, and a consideration was made on the deformation of the reinforced and unreinforced sand. which was obtained through the streo image. It is demonstrated that the deformation pattern is considerably altered by the effect restricting the relative movement of sand grains due to the friction between sand and reinforcement. The reinforcement is considered to play a role in enlarging the deformation zone and lengthening the shear displacement to the failure of the reinforced specimen. It is suggested that the deformation as well as the stresss-train relationship of the compound material should be considered to understand the enhancement in the shear strength of the reinforced sand.

A silicon pressure sensor made of a full bridge of diffused resistors was designed and fabricated using semiconductor integrated circuit process. Thin diaphragms with 30 μm - thick were obtained using anisotropic wet chemical etching technique. However, our device showed strong temperature dependence. A computer system was used to compensate for the temperature dependence of the pressure sensor. Interporlation using polynomial functions was shown to be a useful technique for the calibration and compensation of this device. This system offered a maximum error of ±0.005 kgf/cm^(2). Our results show that we could develop an accurate sensor over a wide temperature range ( -20℃ ~ 60℃ ).

Analysis the Problem of “Shelling” of Specialized Farmers’ Cooperatives and Its Governing Countermeasures: Take Guizhou Province as an Example

Wu Jun(Jun Wu),Luo Yuxin(Yuxin Luo) 아시아사회과학학회 2022 Jornal of Asia Social Science Vol.8 No.1

The problem of “shelling” of specialized farmers’ cooperatives is that farmers’ cooperatives neither insist cooperation essence nor farmer actual participation, and there is no normal operation. The “shelling” problem of farmers’ cooperatives in Guizhou Province is manifested in the three phenomena of “titular form”, “be more in name than in reality” and “unsustainable form”. For the unsustainable farmers’ cooperatives, we can take measures such as improving the organizational structure and management system, exploring joint construction mechanism among the rural credit cooperatives, supply and marketing cooperatives and farmers’ cooperatives, exploring technical services, strengthening the connection of interests and cultivating talent through multiple channels to solve the difficult problems existing in “organization, capital, market, talent, motivation” of the farmers’ cooperatives, achieving the high-quality development.

Background: We sought to evaluate the role of tumor associated macrophages (TAMs) on the promotion of coal tar pitch extract (CTPE)-induced tumorigenesis of human bronchial epithelial cells (BEAS-2B) and tumor metastasis in nude mice, and related mechanisms. Materials and Methods: BEAS-2B cells were first treated with 2.4 mg/mL CTPE for 72 hours. After removal of CTPE, the cells were continuously cultured and passaged using trypsin-EDTA. THP-1 cells were used as macrophage-like cells. BEAS-2B cells under different conditions (n=6/group) were injected into the back necks of nude mice, and alterations of tumor xenograft growth, indicative of tumorigenicity, and tumor metastasis were determined. Pathological changes (tumor nests and microvascular lesions) of HE-stained tumor tissues were also evaluated. The expression of AP-1(c-Jun) in xenografts and metastatic tumors was determined using immunohistochemistry. Results: Tumor size and weight in nude mice transplanted with the mixture of CTPE-induced passage 30 BEAS-2B and THP-1 cells (2:1) were increased compared to those from the CTPE-treated BEAS-2B cells at passage 30 alone at different observation time points. Tumor metastasis to lymph nodes and liver was only detected after transplantation of a mixture the two kinds of cells. The numbers of tumor nests and microvascular lesions, and the expression levels of AP-1 (c-Jun) in tumors from the mixture of two kinds of cells were increased apparently in contrast to those in tumor from the CTPE-treated BEAS-2B cells of passage 30 alone. In addition, there was positive correlation between AP-1 (c-Jun) expression level and the number of microvascular lesions, or between AP-1 (c-Jun) expression level and tumor metastasis in these two groups. Conclusions: TAMs not only facilitate tumorigenesis transformation of CTPE-induced BEAS-2B cells, but also promote tumor growth, angiogenesis and metastasis in nude mice in vivo, which may be mediated by AP-1.

This paper reports the production and characterization of crude xylanase from the newly isolated Humicola sp. Ly01. The highest (41.8 U/ml) production of the crude xylanase was obtained under the optimized conditions (w/v): 0.5% wheat bran, 0.2% KH2PO4, and 0.5% peptone; initial pH 7.0; incubation time 72 h; 30℃; and 150 rpm. A considerable amount of the crude xylanase was induced using hulless barley bran or soybean meal as the carbon source, but a small amount of the enzyme was produced when supplementary urea was used as the nitrogen source to wheat bran. The crude xylanase showed apparent optimal cellulase-free xylanase activity at 60℃ and pH 6.0, more than 71.8% of the maximum xylanase activity in 3.0-30.0% (v/v) ethanol and more than 82.3% of the initial xylanase activity after incubation in 3.0-30.0% (v/v) ethanol at 30℃ for 2 h. The crude xylanase was moderately resistant to both acid and neutral protease digestion, and released 7.9 and 10.9 μmol/ml reducing sugar from xylan in the simulated gastric and intestinal fluids, respectively. The xylooligosaccharides were the main products of the hydrolysis of xylan by the crude xylanase. These properties suggested the potential of the crude enzyme for being applied in the animal feed industry, xylooligosaccharides production, and high-alcohol conditions such as ethanol production and brewing.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by infiltration of immune cells in the synovium. However, the crosstalk of immune cells and synovial fibroblasts is still largely unknown. Here, global miRNA screening in plasma exosomes was carried out with a custom microarray (RA patients vs. healthy controls = 9:9). A total of 14 exosomal miRNAs were abnormally expressed in the RA patients. Then, downregulated expression of exosomal miR-204-5p was confirmed in both the replication (RA patients vs. healthy controls = 30:30) and validation groups (RA patients vs. healthy controls = 56:60). Similar to the findings obtained in humans, a decreased abundance of exosomal miR-204-5p was observed in mice with collagen-induced arthritis (CIA). Furthermore, Spearman correlation analysis indicated that plasma exosomal miR-204-5p expression was inversely correlated with disease parameters of RA patients, such as rheumatoid factor, erythrocyte sedimentation rate, and C-reactive protein. In vitro, our data showed that human T lymphocytes released exosomes containing large amounts of miR-204-5p, which can be transferred into synovial fibroblasts, inhibiting cell proliferation. Overexpression of miR-204-5p in synovial fibroblasts suppressed synovial fibroblast activation by targeting genes related to cell proliferation and invasion. In vivo assays found that administration of lentiviruses expressing miR-204-5p markedly alleviated the disease progression of the mice with CIA. Collectively, this study identified a novel RA-associated plasma exosomal miRNA-204-5p that mediates the communication between immune cells and synovial fibroblasts and can be used as a potential biomarker for RA diagnosis and treatment.
