      • A New Discussion on The Judgment Standard of The Accomplished Crime of Transporting Drugs: From the Perspective of The Dual Regulation of The Theory of Infringement of Legal Interests and The Principle of Behavior Development1

        Liu Nian,Qu Jinshuai 아시아사회과학학회 2021 Jornal of Asia Social Science Vol.5 No.2

        Because the provisions of the criminal law on the crime of transporting drugs are too abstract, there are differences in the understanding of the accomplished standards of the crime of transporting drugs in the academic circles. Judicial staff try cases under the guidance of different theoretical schools, and the phenomenon of different reasoning for the same crime sometimes occurs, which destroys the stability and consistency of judicial decisions. At present, there are many schools in the academic understanding of the accomplished standard of drug transportation crime, such as departure theory, destination theory, reasonable displacement theory, behavior completion theory and so on. Under the same school, there are also different elements of normative understanding.Therefore, it is necessary to clarify the interpretation path of the accomplished standard of drug transportation crime and get out of the theoretical loss.Combined with the theory of infringement of legal interests, the principle of behavior development and the examination of behavior patterns, it is considered that the theory of drugs entering the transportation state under the differentiation system is the accomplished judgment standard for the legitimacy and rationality of the crime of transporting drugs.In the case of integration of people and goods, the departure of drugs means completion, while in the case of separation of people and goods, it is necessary to take drugs entering the transportation state as the substantive standard and analyze the specific types.The system structure of the theory of drugs entering the transportation state under the differentiation system has the guidance of functionalism and teleology, which is conducive to the realization of crime control and human rights protection.

      • Study on the accomplished judgment standard of the crime of transporting drugs

        Liu Nian,Qu Jinshuai 아시아사회과학학회 2021 Jornal of Asia Social Science Vol.3 No.1

        Because the provisions of the criminal law on the crime of transporting drugs are too abstract, the judicial staff have different judgments on the accomplished crime of transporting drugs, and the phenomenon of different reasons for the same crime sometimes appears, which undermines the stability and consistency of the judicial judgment. In the trial practice, there are opposites in judging the accomplishment standard of the crime of transporting drugs, such as departure theory, reasonable displacement theory, behavior completion theory, entering the means of transport theory, leaving the scene theory and holding behavior+purpose behavior theory . Combined with the legal logic and legislative spirit of the crime of transporting drugs, it is considered that drugs enter the transportation state is the accomplished judgment standard of the crime of transporting drugs. In the case of the integration of people and goods, the shipment of drugs means accomplishment, while in the case of the separation of people and goods, it is necessary to take drugs entering the transportation state as the substantive standard to analyze the specific types. The system structure of the theory that drugs enter the transportation state under the discrimination system has both functionalism and purposiveness, which is conducive to promoting the realization of crime control and human rights protection functions.

        A General Self-Propagating High-Temperature Synthesis Method for Fast and Easy Preparation of Metal Oxide Nanostructures from Low Melting Point Metals

        Nian Liu,Guodong Zhang,Yadong Xiao,Zhifang Peng 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.1

        Different metal oxide nanostructures including SnO2 nanowires, SnO2 nanoparticles, ZnO nanorods, ZnO nanoparticles, Al2O3 nanoparticles, SiO2 nanoarray, and SnO2–SiO2 core–shell nanoparticles, can be selectively synthesized by Self-propagating High-temperature Synthesis (SHS) method with different reaction systems. This method can be easily applied to synthesize metal oxide nanostructures with high yield and excellent purity from low melting point metals in a very short time at low cost without the need for any sophisticated equipment. The composition of reaction system has a crucial influence on the reaction temperature and morphology of the end products. Compared with nanoparticles, nanowires or nanorods can be obtained at lower reaction temperature. And introducing the chemical containing silicon to the reaction system allows the formation of SiO2 nanoarray and SnO2–SiO2 core–shell nanoparticles.

      • 실크로드 경제대의 신장 물류 기지 구축 전략

        유념(Liu Nian),이성준(Sung Joon Lee) 한국산학기술학회 2014 한국산학기술학회 학술대회 Vol.- No.-

        중국은 동부지역을 선두로 고도경제성장을 지속적으로 이룩하였으나 상대적으로 발전이 늦은 서부 지역의 경제부흥에 관심을 기울이고 있다. “실크로드 경제대”는 중국 서부 경제발전 추세에 맞추어 새롭게 구축되고 있으며, 실크로드 경제대는 고대 실크로드 개념을 기반으로 형성된 새로운 경제발전 구역이다. 동쪽으로는 아시아 태평양 경제권과 연계되어있다. “실크로드 경제대”는 중국에서 가장 길 고 발전 잠재력이 큰 경제구역이다. 본 논문은 최근 몇 년간의 실크로드의 개발에 의하여 취득한 성과 를 분석하고 향후 중국 신장을 중심으로 하는 물류기지 구축전략을 연구했다.

        The Effects of β-tricalcium Phosphate 3D Scaffold in-situ Cryopreservation on the Migration Rate and Osteogenic Ability of Mesenchymal Stem Cells

        Liu Yang,Hai-Ying Sun,Nian Min Qi,Wen-Song Tan 한국생물공학회 2012 Biotechnology and Bioprocess Engineering Vol.17 No.1

        To readily supply seed cells for tissue engineering and ensure their constant availability for experiments,it is imperative to establish an in-situ cryopreservation method for cell storage. We investigated the effects of a β-tricalcium phosphate (β-TCP) 3D scaffold in-situ cryopreservation method on the migration rate and osteogenic ability of mesenchymal stem cells (MSCs). Compared to using a 2D plate culture and trypsinized cryopreservation, MSCs on β-TCP 3D scaffolds demonstrated a higher amplification rate, and the harvest and survival rates (HSR) increased from 55.9 to 81.3% when the 3D in-situ cryopreservation method was applied. The cell migration rate and alkaline phosphatase (ALP) activity were unaffected after in-situ cryopreservation, and unexpectedly,the Specific ALP activity of migrating cells was higher than that of non-cryopreserved cells, suggesting that the cell-scaffold combination could be cryopreserved using the present protocol without loss of proliferative or osteogenic potential. These findings highlight a methodology for 3D scaffold in-situ cryopreservation and passage for MSC production in bone tissue engineering, and present the possibility of designing a perfusion cells/scaffold factory for scale-up production.

        A unified solution for vibration analysis of plates with general structural stress distributions

        Nian Yang,Lu-Yun Chen,Hong Yi,Yong Liu 대한조선학회 2016 International Journal of Naval Architecture and Oc Vol.8 No.6

        Complex stress distributions often exist in ocean engineering structures. This stress influences structural vibrations. Finite Element Methods exhibit some shortcomings for solving non-uniform stress problems, such as an unclear physical interpretation, complicated operation, and large number of computations. Analytical methods research considers mainly uniform stress problems, and often, their methods cannot be applied in practical marine structures with non-uniform stress. In this paper, an analytical method is proposed to solve the vibration of plates with general stress distributions. Non-uniform stress is expressed as a special series, and the stress influence is inserted into a vibration equation that is solved through decoupling to obtain an analytical solution. This method has been verified using numerical examples and can be used in arbitrary stress distribution cases. This method requires fewer computations and it provides a clearer physical interpretation, so it has advantages in some qualitative research.

      • Roles of Signaling Pathways in the Epithelial-Mesenchymal Transition in Cancer

        Liu, Xia,Yun, Fen,Shi, Lin,Li, Zhe-Hai,Luo, Nian-Rong,Jia, Yong-Feng Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.15

        The epithelial-mesenchymal transition (EMT) is a cellular process though which an epithelial phenotype can be converted into a phenotype of mesenchymal cells. Under physiological conditions EMT is important for embryogenesis, organ development, wound repair and tissue remodeling. However, EMT may also be activated under pathologic conditions, especially in carcinogenesis and metastatic progression. Major signaling pathways involved in EMT include transforming growth factor ${\beta}(TGF-{\beta})$, Wnt, Notch, Hedgehog and other signaling pathways. These pathways are related to several transcription factors, including Twist, Smads and zinc finger proteins snail and slug. These interact with each other to provide crosstalk between the relevant signaling pathways. This review lays emphasis on studying the relationship between EMT and signaling pathways in carcinogenesis and metastatic progression.

        Assessing the effect of surface hydrophobicity/hydrophilicity on pollutant leaching potential of biochar in water treatment

        Nian Hong,Qin Cheng,Ashantha Goonetilleke,Erick R. Bandala,An Liu 한국공업화학회 2020 Journal of Industrial and Engineering Chemistry Vol.89 No.-

        This study investigated the role of surface hydrophobicity/hydrophilicity of biochar on its pollutantleaching potential (pollutants originally in biomass feedstock), including nutrients, organic matter andmetals, in water treatment applications. The study outcomes confirmed that biochar with greaterhydrophilic surface leached comparatively higher loads of nutrients and organic matter compared tobiochar with mostly hydrophobic surface, while biochar with greater hydrophilic surface leached lowermetal loads. This trend is attributed to the changes to the physical and chemical properties of biocharincluding specific surface area and surface functional groups, as well as being related to the binding forcesbetween the biochar surface and the different compounds. Further, the study results substantiated thesignificant influence of surface characteristics of biochar, and its preparation process on pollutantleaching potential. The study outcomes provide essential guidance on the appropriate use of biochar asan adsorbent in water treatment, including raw biomass selection and the production processes to beadopted.

        Effect of seismic acceleration directions on dynamic earth pressures in retaining structures

        Nian, Ting-Kai,Liu, Bo,Han, Jie,Huang, Run-Qiu Techno-Press 2014 Geomechanics & engineering Vol.7 No.3

        In the conventional design of retaining structures in a seismic zone, seismic inertia forces are commonly assumed to act upwards and towards the wall facing to cause a maximum active thrust or act upwards and towards the backfill to cause a minimum passive resistance. However, under certain circumstances this design approach might underestimate the dynamic active thrust or overestimate the dynamic passive resistance acting on a rigid retaining structure. In this study, a new analytical method for dynamic active and passive forces in c-${\phi}$ soils with an infinite slope was proposed based on the Rankine earth pressure theory and the Mohr-Coulomb yield criterion, to investigate the influence of seismic inertia force directions on the total active and passive forces. Four combinations of seismic acceleration with both vertical (upwards or downwards) and horizontal (towards the wall or backfill) directions, were considered. A series of dimensionless dynamic active and passive force charts were developed to evaluate the key influence factors, such as backfill inclination ${\beta}$, dimensionless cohesion $c/{\gamma}H$, friction angle ${\phi}$, horizontal and vertical seismic coefficients, $k _h$ and $k_v$. A comparative study shows that a combination of downward and towards-the-wall seismic inertia forces causes a maximum active thrust while a combination of upward and towards-the-wall seismic inertia forces causes a minimum passive resistance. This finding is recommended for use in the design of retaining structures in a seismic zone.
