본 연구에서는 중국 소수민족 교육정책에 따라 연변주 조선족 교육정책이 어떤 형태로 전개되고 있는지를 실증적으로 분석할 필요가 있다는 문제의식에 근거하여 근원이 되는 민족에 대한 민족정체성과 본국의 국가정체성의 조화를 위한 문화교차적 관점에서의 과경민족 교육 모델 정립을 위한 시사점을 도출하고자 하였다. 연변주 조선족 교육정책은 학제 구성, 과목배치 및 수업계획, 이중언어 교육 등의 체제 정비가 이루어졌다, 그러나 이러한 체제 정비 이후 교육과정 구성 등에 있어서는 민족정체성과 국가정체성의 조화 방향을 결정하는 것이 우선되어야 할 것이다. 과경민족인 연변주 조선족의 생활근거지가 중국이라는 점에서 민족정체성만을 강조하기에는 현실적인 어려움이 있음을 감안하고, 교육방법적 측면에서 문화교차적 성격이 부각되도록 해야 할 것이다. 특히 교육과정 설계에 있어서 민족정체성에 대한 객관적 사실 인지가 우선되어야 할 것이며, 학교 소재 지역의 지리적 특성을 고려하여 민족문화 교육과정을 구성하려는 노력이 필요하다. 구체적인 방법으로 백두산, 도문강 등의 자연자원을 이용하거나 청산리 전투지, 명동학교, 일본간도총영사관 옛터 등 역사 문화 자원을 이용하여 조사와 연구를 전개하는 방법을 고려할 수 있다. The purpose of this study is to propose the direction of intercultural education model with the concept of the ethnic identity and national identity in China’s cross-boundary nationality area, focused the ethnic Koreans living in China. It is to determine the harmony of direction must be a priority that cross-boundary nationality is needed the harmony between the ethnic identity and national identity and they should be select the ethnic identity under the Covenant within the category of national identity. In particular, it is necessary to establish the objective of the national identity education in the design curriculum, and the efforts to construct a national cultural education curriculum are needed considering the geographic characteristics of the school region.

Jiang Jin-gang,Wang Zhao,Zhang Yong-de,Jiang Ji-xiong,Niu Suo-liang,Liu Yi 보안공학연구지원센터 2014 International Journal of Control and Automation Vol.7 No.12

The archwire bending is one of processes the most frequently used in the orthodontic treatment. Furthermore, the springback of sheet metal, which is defined as elastic recovery of the part during unloading, should be taken into consideration so as to produce formed archwire within acceptable tolerance limits. In this paper, the springback angle of different alloy archwires (including NiTi alloy wire, Beta-Ti alloy wires, Chinese stainless steel wires, and Australian stainless steel wires) were performed by the theoretical calculation based on large deformation theory and the finite element analysis. A series of numerical simulations has been conducted for the bending test, which physically simulates the actual bending of alloy archwire with a robotic apparatus. The finite element analysis of springback is shown to be very consistent with the theoretical calculation results.

<P>Abstract</P><P><B><I>Background:</I></B> Leflunomide (LEF) and benazepril have renoprotective effects on diabetic nephropathy (DN) through their anti-inflammatory and anti-fibrotic activities. This study investigated whether combined treatment using LEF and benazepril affords superior protection compared with the respective monotherapies. <B><I>Methods:</I></B> Diabetes was induced with streptozotocin (STZ, 65 mg/kg) by intraperitoneal injection in male Wistar rats. Two weeks after STZ injection, diabetic rats were treated daily for 12 weeks with LEF (10 mg/kg), benazepril (10 mg/kg), or a combination of both. Basic parameters (body weight, fasting blood glucose level, and 24 h urinary protein excretion), histopathology, inflammatory [inflammatory cell infiltration (ED-1), monocyte chemoattractant protein-1 (MCP-1), and Toll-like receptor-2 (TLR-2)] and glomerulosclerotic factors [transforming growth factor-β<SUB>1</SUB> (TGF-β<SUB>1</SUB>) and connective tissue growth factor (CTGF)], and oxidative stress (8-hydroxy-2'-deoxyguanosine, 8-OHdG) were studied. <B><I>Results:</I></B> Benazepril or LEF treatment significantly prevented body weight loss and 24 h urinary protein excretion induced by diabetes; combined treatment with LEF and benazepril further improved these parameters compared with giving each drug alone (all p < 0.01). Increased expression of inflammatory (MCP-1 and TLR-2) and glomerulosclerotic (TGF-β<SUB>1</SUB> and CTGF) factors in diabetic rat kidney was reduced by treatment with either LEF or benazepril and was further reduced by the combined administration of the two drugs (p < 0.01). These effects were accompanied by suppression of urinary 8-OHdG excretion. There was no significant between-group difference in blood glucose level. <B><I>Conclusions:</I></B> LEF treatment lessens DN, and combined treatment with LEF and benazepril provides synergistic effects in preventing DN.</P><P>© 2014 S.

( Hai Yan Zhao ),( Hui Ying Li ),( Jian Jin ),( Ji Zhe Jin ),( Long Ye Zhang ),( Mei Ying Xuan ),( Xue Mei Jin ),( Yu Ji Jiang ),( Hai Lan Zheng ),( Ying Shun Jin ),( Yong Jie Jin ),( Bum Soon Choi ) 대한내과학회 2021 The Korean Journal of Internal Medicine Vol.36 No.0

Background/Aims: Accumulating evidence indicates that L-carnitine (LC) protects against multiorgan damage through its antioxidant properties and preservation of the mitochondria. Little information is available about the effects of LC on renal fibrosis. This study examined whether LC treatment would provide renoprotection in a rat model of unilateral ureteral obstruction (UUO) and in vitro. Methods: Sprague-Dawley rats that underwent UUO were treated daily with LC for 7 or 14 days. The influence of LC on renal injury caused by UUO was evaluated by histopathology, and analysis of gene expression, oxidative stress, mitochondrial function, programmed cell death, and phosphatidylinositol 3-kinase (PI3K)/ AKT/forkhead box protein O 1a (FoxO1a) signaling. In addition, H₂O₂-exposed human kidney cells (HK-2) were treated with LC. Results: LC treatment inhibited expression of proinflammatory and profibrotic cytokines, and was followed by a significant attenuation of tubulointerstitial inflammation and fibrosis. The increased oxidative stress caused by UUO was associated with mitochondrial dysfunction and excessive apoptosis and autophagy via PI3K/AKT/FoxO1a-dependent signaling, and this was abrogated by administration of LC. In H₂O₂-exposed HK-2 cells, LC decreased intracellular production of reactive oxygen species, and suppressed expression of profibrotic cytokines and reduced the number of apoptotic cells. Conclusions: LC protects against the progression of tubulointerstitial fibrosis in an obstructed kidney.

Nickel‑based N/S‑dual doped graphene/carbon nanotubes electrocatalyst for oxygen evolution

Jin‑Chi Jiang,Jiamin Liu,Yingai Piao,Mei‑Shan Zhang,Long‑Yue Meng 한국탄소학회 2023 Carbon Letters Vol.33 No.1

Hydrogen energy is a promising source of renewable and clean energy for various industries, such as chemical, automobile, and energy industries. Electrolysis of water is one of the basic methods for the production of hydrogen energy. However, the high overpotential of the oxygen evolution reaction (OER) in water electrolysis has hindered the effective production of hydrogen using this method. Thus, the development of high-efficiency non-precious metal-based electrocatalysts for OER is extremely significant. In this study, we adopted a one-step hydrothermal method to fabricate Ni-based catalysts with N/Sdual doped graphene oxide/carbon nanotube (GO/CNT) supports using thiourea ( CH4N2S) and urea as the S source and the N source. It was observed that the amount of thiourea utilized in the synthesis of the catalyst affected the morphology, composition, and the electrochemical properties of the catalyst. For a GO/CNT-to-thiourea mass ratio of 1:10, the catalyst exhibited the highest activity, where the OER overpotential was 320 mV at a current density of 10 mA/cm2. This was attributed to the high specific surface area, high conductivity, and fast electron transport channels of the N/S-dual doped GO/ CNT composite. Furthermore, sulfurization of the Ni particles to form nickel sulfide played a significant role in enhancing the catalytic performance.

A Novel Preserving Client Privacy and Designate Verifier Auditing Scheme for Cloud Storage

Jiang Xu,Wenliang Chen,Sai Ji,Yongjun Ren,Jin Wang 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.1

Cloud storage is now an important development trend in information technology. To ensure the integrity of data storage in cloud storing, researchers have present some proof of storage schemes. In some cases, the ability to check data possession is delegated by data owners. Hence, the delegable provable data possession and proxy provable data possession are proposed. However the schemes are not secure since the proxy or designated verifier stores some delegation information in cloud storage servers. In this paper, we propose PC-DV POS scheme, which can preserve clients’ privacy and designate a verifier by the client signed the data blocks. In particular, we utilize group signatures and key exchange to construct homomorphic authenticators, so that only the designated verifier is able to check the integrity of shared data for users without retrieving the entire data, and cannot reveal the identities of signers on all blocks in shared data.

It is realized by one-way rotation ratchet mechanism, which is consistent of slider-crank mechanism and double pawl ratchet mechanism. Dressing change is automatically realized by patient manual control rope. This reduces the labor intensity of the medical staff, shortens the waiting time of the patients. This device has the advantage of low cost, large market space.

Numerical simulation on mining effect influenced by a normal fault and its induced effect on rock burst

Jiang, Jin-Quan,Wang, Pu,Jiang, Li-Shuai,Zheng, Peng-Qiang,Feng, Fan Techno-Press 2018 Geomechanics & engineering Vol.14 No.4

The study of the mining effect influenced by a normal fault has great significance concerning the prediction and prevention of fault rock burst. According to the occurrence condition of a normal fault, the stress evolution of the working face and fault plane, the movement characteristics of overlying strata, and the law of fault slipping when the working face advances from footwall to hanging wall are studied utilizing UDEC numerical simulation. Then the inducing-mechanism of fault rock burst is revealed. Results show that in pre-mining, the in situ stress distribution of two fault walls in the fault-affected zone is notably different. When the working face mines in the footwall, the abutment stress distributes in a "double peak" pattern. The ratio of shear stress to normal stress and the fault slipping have the obvious spatial and temporal characteristics because they vary gradually from the higher layer to the lower one orderly. The variation of roof subsidence is in S-shape which includes slow deformation, violent slipping, deformation induced by the hanging wall strata rotation, and movement stability. The simulation results are verified via several engineering cases of fault rock burst. Moreover, it can provide a reference for prevention and control of rock burst in a fault-affected zone under similar conditions.
