본 연구는 한국과 중국의 대학생을 대상으로 이들의 경제금융윤리의식을 비교연구한 것이다. 구체적으로 연구대상의 성별·학년별·수강한 경제 교과 수별 경제금융윤리의식의 실태와 가정 환경적 요인이 학생들의 경제금융의식에 미치는 영향을 실증적으로 분석하였다. 조사방법은 리커트 척도 제작법에 의해 4점 척도로 구성된 질문지법을 사용하였으며, 통계처리는 SPSS를 이용하였다. 연구결과는 다음과 같다. 첫째, 성별에 따른 경제금융윤리의식의 경우 한국의 경우에는 여학생이 남학생보다 높지만 유의적인 차이가 없는 것으로 나타났다. 중국의 경우에는 여학생이 남학생보다 다소 높게 나타나고 차이가 있는 것으로 나타났다. 둘째, 학년에 따른 경제금융윤리의식의 경우에는 한국과 중국 모두에서 통계적으로 유의한 차이를 보여 학년이 높아질수록 경제금융윤리의식이 높은 것으로 나타났다. 셋째, 수강한 경제 교과 수에 따른 경제금융윤리의식의 경우 양국 모두 수강한 경제 교과 수가 많아질수록 경제금융윤리의식이 낮다고 할 수 있다. 넷째, 출생지에 따른 경제금융윤리의식의 경우에는 출생지에 따라 유의미한 차이를 보였으며 대도시 지역의 대학생이 상대적으로 높게 나타났다. 다섯째, 계층에 따른 경제금융윤리의의 경우 계층간에 유의미한 차이가 없는 것으로 나타났지만 부모의 학력에 따른 경제금융윤리의식의 경우에는 부모의 학력이 높아질수록 경제금융윤리의식이 높게 나타났다. The economic growth was considered as the most important national value during the process of industrialization and development. While the importance of social morality and social values was neglected. So, the deficiency of the economic-financial ethnical consciousness caused many social problems in both Korea and China. The principal objective of this study is to analyze the effectiveness of the curriculum of economics major college in economic-financial ethnical. First, various materials and preceeding studies were referred. Second, the average level of economic-financial ethnical consciousness in both korea and china. Third, the effects of the sex, the grade, the economic lessons and the family environment on the economic-financial ethnical of the college students who are studied in Gyeongsang National University and ShanDong University. For this study a questionnaire was distributed to some college students, and the number of observation is 400(the number of korea students is 200 and the number of Chinese students is 200). The collected questionnaire were analyzed on the basis of the relation between the independent variables(sex, grade, economic lessons, family environment) and the dependent variables(economic-financial ethnical consciousness). Family environment variable was relation with social economic status and economic status was subdivided into parent`s education, family income and birthplace. SPSS was used for all statistical analysis of this study. Based on the design, the study was carried out, and the result are as the followings. First, female students in both Korea and China have more desirable economic-financial ethnical consciousness than male students. Second, Korea students in high grade have higher economic-financial ethnical consciousness than those in low grade. However, Chinese students in low grade have higher economic-financial ethnical consciousness than those in high grade. Third, Korea students who study more economic-financial lessons have higher economic-financial ethnical consciousness. However, Chinese students is opposite to Korea students. In China, the students who study less economic-financial lessons have higher economic-financial ethnical consciousness than those students who study more economic-financial lessons. This means that the problem for Chinese school education still exists. Fourth, the factors of family environment don`t effect that much on the economic-financial ethnical consciousness of the Korea college students. But the factors of family environment effect that much on the economic-financial ethnical consciousness of the Chinese college students. Finally, further research about college students` economic-financial ethics and more detail information of other college students about the economic-financial ethics are needed.

Lin Ma,Xiaoping Zhou,Limei Xu,Xuyao Xu,Lingling Zhang 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2016 NANO Vol.11 No.2

We introduce a two-step hydrothermal and microwave method to prepare novel SnO2/MoS2 composites. The as-prepared samples are well characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). The experimental results indicate that the SnO2/MoS2 composites are composed of MoS2 nanosheets and ultrafine SnO2 nanoparticles with mean size of 3–4 nm which are well-distributed and anchored on the surface of MoS2 nanosheets. The resultant composites demonstrate prominently improved electrochemical performances, which could be attributed to the unique and robust microstructures and synergetic effect between MoS2 and SnO2.

One-Pot Hydrothermal Synthesis of Sulfur-Doped SnO2 Nanoparticles and their Enhanced Photocatalytic Properties

Lin Ma,Limei Xu,Xuyao Xu,Xiaoping Zhou,Lingling Zhang 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2016 NANO Vol.11 No.3

Sulfur-doped SnO2 nanoparticles with ultrafine sizes have been successfully prepared by a one-pot hydrothermal method. The obtained samples are characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), high resolution transmission electron microscopy (HRTEM), thermogravimetric (TG), analyzer UV-Vis spectroscopy, photoluminescence (PL) and electrochemical impedance spectroscopy (EIS). The experimental results indicate that the doping level of sulfur element as well as the bandgaps of SnO2 can be controlled to a certain extent by varying the amount of L-cysteine (L-cys). When evaluated as photocatalysts in the degradation of rhodamine B (RhB) and reduction of Cr(VI) under visible light region, the resultant sulfur-doped SnO2 nanoparticles demonstrate obviously enhanced photocatalytic activities due to the markedly improved visible light response and effective separation of the photo-generated electron–hole pairs.

Grain-Refinement and Mechanical Properties Optimisation of A356 Casting Al by Ultrasonic-Assisted Friction Stir Processing

Lin Ma,Changzhuang Zhou,Yao Shi,Qinghe Cui,Shude Ji,Kang Yang 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.12

Conventional friction stir processing (FSP) and ultrasonic-assisted friction stir processing (Ua-FSP) were applied to modifythe microstructure and enhance the mechanical properties of as-cast A356 aluminium alloy. A series of experiments withdifferent processing parameters were conducted in these two processing methods. Forming characteristics, grain-refinement,and mechanical properties in FSP and Ua-FSP were compared to determine the effect of ultrasound. The results revealed thatultrasound improved the grain-refinement level in both grain size and grain uniformity. Further, the effect of ultrasound onmicrostructural evolution was more significant with relatively high processing heat-input. Ultrasonic vibration also positivelyaffected the hardness, tensile strength, and elongation.

Transient aerodynamic forces of a vehicle passing through a bridge tower's wake region in crosswind environment

Ma, Lin,Zhou, Dajun,Han, Wanshui,Wu, Jun,Liu, Jianxin Techno-Press 2016 Wind and Structures, An International Journal (WAS Vol.22 No.2

Super long-span bridges provide people with great convenience, but they also bring traffic safety problems caused by strong wind owing to their high decks. In this paper, the large eddy simulation together with dynamic mesh technology in computational fluid dynamics (CFD) is used to explore the mechanism of a moving vehicle's transient aerodynamic force in crosswind, the regularity and mechanism of the vehicle's aerodynamic forces when it passes through a bridge tower's wake zone in crosswind. By comparing the calculated results and those from wind tunnel tests, the reliability of the methods used in the paper is verified on a moving vehicle's aerodynamic forces in a bridge tower's wake region. A vehicle's aerodynamic force coefficient decreases sharply when it enters into the wake region, and reaches its minimum on the leeward of the bridge tower where exists a backflow region. When a vehicle moves on the outermost lane on the windward direction and just passes through the backflow region, it will suffer from negative lateral aerodynamic force and yaw moment in the bridge tower's wake zone. And the vehicle's passing ruins the original vortex structure there, resulting in that the lateral wind on the right side of the bridge tower does not change its direction but directly impact on the vehicle's windward. So when the vehicle leaves from the backflow region, it will suffer stronger aerodynamic than that borne by the vehicle when it just enters into the region. Other cases of vehicle moving on different lane and different directions were also discussed thoroughly. The results show that the vehicle's pneumatic safety performance is evidently better than that of a vehicle on the outermost lane on the windward.

Transgenic rice expressing Bacillus thuringiensis (Bt) Cry1Ac and Cry2Aa toxins have proven resistant to lepidopteran pests in China, including the striped stem borer, Chilo suppressalis. Identifying the molecular mechanisms through which Cry toxins affect insect pests is essential, both for understanding the nature of their toxicity, and for assessing the potential for the development of resistance to such toxins. In this study, both onedimensional gel electrophoresis (1-DE), combined ligand blots and mass spectrometry, were used to identify proteins binding to the Cry1Ac and Cry2Aa toxins in brush border membrane vesicles (BBMVs) of the C. suppressalis larvae midgut. Aminopeptidase-N (APN), alkaline phosphatase (ALP), cadherin-like (CAD), ATP-binding cassette transporter subfamily C1 protein (ABCC1), actin, ATPase, alpha amylase, and heat shock protein cognate (HSPC), were detected in Cry1Ac binding bands, and APN, actin, ATPase and HSPC were identified as Cry2Aa potential binding proteins. The novel potential binding protein, delta-aminolevulinic acid dehydratase, was also detected in both Cry1Ac and Cry2Aa binding bands. This is the first study to comprehensively identify the proteins that bind to Cry1Ac and Cry2Aa toxins in C. suppressalis.

Lin Chuan Ma(마림천),Jae Ho Hwang(황재호),Nack Hyun Choi(최낙현),Jae-Moung Kim(김재명) 한국통신학회 2008 韓國通信學會論文誌 Vol.33 No.12A

Non-line-of-sight (NLOS) propagation can severely weaken the accuracy of ranging and localization in wireless location systems. NLOS bias mitigation techniques have recently been proposed to relieve the NLOS effects, but positively rely on the capability to accurately distinguish between LOS and NLOS propagation scenarios. This paper proposes an energy-capture-based NLOS identification method for LDR-UWB systems, based on the analysis of the characteristics of the channel impulse response (CIR). With this proposed energy capture method, the probability of successfully identifying NLOS is much improved than the existing methods, such as the kurtosis method, the strongest path compare method, etc. This NLOS identification method can be employed in adaptive modulation scheme to decrease bit error ratio (BER) level for certain signal-to-noise ratio (SNR). The BER performance with the adaptive modulation can be significantly enhanced by selecting proper modulation method with the knowledge of channel information from the proposed NLOS identification method.
