汉•韩语持续/进行体的“他者”认识研究

Ying Qi,Qingnan Wu 부산대학교 중국연구소 2017 Journal of China Studies Vol.20 No.3

This paper deals with a comparative analysis of the characteristics of the verb that can appear in the Chinese going-on expression “V-着” and the Korean going-on expression “V-고/어 있다” by using the theory of ‘span of duration’, and the result is that the verb which can combine with the Chinese aspect particle “着” or the Korean auxiliary verb “(-고/어) 있다” must possess the definite feature of “span of duration”. In other words, the verb, which is able to integrate with the Chinese aspect particle “着” and the Korean auxiliary verb “(-고/어) 있다”, can not convey the syntactic meaning of the action’s going-on, unless they do have the clear distinction of “span of duration”. By means of contrastive analysis, we can discover the fact that the Chinese going-on aspect “着” own simultaneously both the succession of the action and the succession of the static state, while when it comes to Korean language, the auxiliary verb differs in the forms when expressing the succession of the action or the static state, which means the accuracy of the going-on aspect in Korean. On the other hand, this paper made further efforts to narrow the range of the object of this study into the verb that can appear in the passive sentence. In order to figure out the characteristics of the passive semantics about the “V+‘going-on’”, this paper also tried to analyze the limiting factors of the verb that can combine with the Chinese and Korean going-on expression in the passive sentence from the perspective of semantics. In the end, this paper summed up the reasons why the verbs can’t be used in the passive sentence of “V+‘going-on’” through analyzing the passive sentences’ meaning, the tense and aspect of the verb, and the semantic collocations. By this way, we can find that there are many similarities and distinctions in the verbs which can turn up in the Chinese and Korean passive sentences. Firstly, almost all the dynamic verbs in the passive sentences have the characteristics of “span of duration”, which belongs to the movement or the state after the movement. Secondly, while the Action Verb that can combine with‘着’in the Chinese passive sentences can indicate the succession of actions, the Positional Verb can reflect the succession of the static state. As to the Korean language, the passive verbs that are in collocation with ‘-고 있다’ can present the feature of the actions’ succession, and the ones that are in collocation with ‘-어 있다’ can show the static state’s succession.

Performance Assessment of Arch-shaped Primary Lining during Construction in Weak Rock Shallow-buried Tunnel

Yingqi Liu,Xiedong Zhang,Jiali Li,Zhihua Zhang,Hang Zhang 대한토목학회 2019 KSCE Journal of Civil Engineering Vol.23 No.1

Tunnels excavated through weak rock masses using the Shallow Tunneling Method (STM) call for rigid lining support to withstand and constrain the mobility of the unstable rock where its performance needs to be assessed with field measured data in case of potential failure. For fear of any further hazards after the occurrence of a rock fall at chainage km 86,685 m in the Longsheng Tunnels, the monitoring plan was specially modified to accurately obtain the relative vertical and horizontal displacements of the steel rib component in the arch-shaped composite rigid primary lining that was simply placed on the heading. In this paper, the weak rock masses’ interaction with the rigid lining is treated as unknown distributed loads divided into radial and tangential directions, where the influence line theory is applied to better understand the response of the lining so as to facilitate a displacement-based back analysis for unknown rock mass loads and the resultant stress outcome. By comparing the back analyzed stress outcome with the measured one, the proposed performance assessing method for the unclosed arch-shaped lining was proven to be time efficient with acceptable accuracy, which is of considerable application potential and can provide a reference for similar engineering.

Event-based Finite-time Boundedness of Discrete-time Network Systems

Yingqi Zhang,Miaojun Zhan,Yan Shi,Caixia Liu 제어·로봇·시스템학회 2020 International Journal of Control, Automation, and Vol.18 No.10

This paper deals with the event-based finite-time H∞ control problem of discrete-time network control systems with norm bounded input disturbances and nonlinear stochastic functions. A network-induced delay stochastic model is first constructed by an event-triggered approach. Utilizing stochastic analysis and eventtriggered schemes, conditions on stochastic finite-time (FT) boundedness and stochastic H∞ FT boundedness are then derived for the network model. Subsequently, an event-based finite-time controller and an event-triggered matrix are co-designed to ensure that the stochastic model is stochastically FT bounded or stochastically H∞ FT bounded by utilizing a matrix decomposition scheme. All derived criteria can be solved in terms of convex optimal method, and numerical examples demonstrate the validity of obtained results as well.

Vibrations of a taut horizontal cable subjected to axial support excitations considering nonlinear quasi-static responses

Jiang Yi,Yingqi Liu 국제구조공학회 2023 Structural Engineering and Mechanics, An Int'l Jou Vol.86 No.2

To calculate the vibrations of a tout cable subjected to axial support excitations, a nonlinear relationship of cable force and the support displacement under static situations are employed to depict the quasi-static vibration of the cable. The dynamic components of quasi-static vibration are inputted as “direct loads” to cause the parametric vibrations on the cable. Both the governing equations of motion and deformation compatibility for parametric vibrations are then derived, which indicates the high coupling of cable parametric force and deformation. Numerical solutions, based on the finite difference method, are put forward for the parametric vibrations, which is validated by the finite element method under periodic axial support excitations. For the quasi-static response, the shorter cables are more sensitive to support excitations than longer ones at small cable force. The quasi-static cable force makes the greatest contribution to the total cable force, but the parametric cable force is responsible for the occurrence of cable loosening at large excitation amplitudes. Moreover, this study also revealed that the traditional approach, assuming a linear relationship between quasi-static cable force and axial support displacement, would result in some great error of the cable parametric responses.

A refinement and abstraction method of the SPZN formal model for intelligent networked vehicles systems

Yang Liu,Yingqi Fan,Ling Zhao,Bo Mi 한국인터넷정보학회 2024 KSII Transactions on Internet and Information Syst Vol.18 No.1

Security and reliability are the utmost importance facts in intelligent networked vehicles. Stochastic Petri Net and Z (SPZN) as an excellent formal verification tool for modeling concurrent systems, can effectively handles concurrent operations within a system, establishes relationships among components, and conducts verification and reasoning to ensure the system's safety and reliability in practical applications. However, the application of a system with numerous nodes to Petri Net often leads to the issue of state explosion. To tackle these challenges, a refinement and abstraction method based on SPZN is proposed in this paper. This approach can not only refine and abstract the Stochastic Petri Net but also establish a corresponding relationship with the Z language. In determining the implementation rate of transitions in Stochastic Petri Net, we employ the interval average and weighted average method, which significantly reduces the time and space complexity compared to alternative techniques and is suitable for expert systems at various levels. This reduction facilitates subsequent comprehensive system analysis and module analysis. Furthermore, by analyzing the properties of Markov Chain isomorphism in the case study, recommendations for minimizing system risks in the application of intelligent parking within the intelligent networked vehicle system can be put forward.

JunPei Zhou,YingQi Gu,ChangSong Zou,MingHe Mo 한국미생물학회 2007 The journal of microbiology Vol.45 No.2

The objective of this study was to analyze the phylogenetic composition of bacterial community in the soil of an earth-cave (Niu Cave) using a culture-independent molecular approach. 16S rRNA genes were amplified directly from soil DNA with universally conserved and Bacteria-specific rRNA gene primers and cloned. The clone library was screened by restriction fragment length polymorphism (RFLP), and representative rRNA gene sequences were determined. A total of 115 bacterial sequence types were found in 190 analyzed clones. Phylogenetic sequence analyses revealed novel 16S rRNA gene sequence types and a high diversity of putative bacterial community. Members of these bacteria included Proteobacteria (42.6%), Acidobacteria (18.6%), Planctomycetes (9.0%), Chloroflexi (Green nonsulfur bacteria, 7.5%), Bacteroidetes (2.1%), Gemmatimonadetes (2.7%), Nitrospirae (8.0%), Actinobacteria (High G+C Gram-positive bacteria, 6.4%) and candidate divisions (including the OP3, GN08, and SBR1093, 3.2%). Thirty-five clones were affiliated with bacteria that were related to nitrogen, sulfur, iron or manganese cycles. The comparison of the present data with the data obtained previously from caves based on 16S rRNA gene analysis revealed similarities in the bacterial community components, especially in the high abundance of Proteobacteria and Acidobacteria. Furthermore, this study provided the novel evidence for presence of Gemmatimonadetes, Nitrosomonadales, Oceanospirillales, and Rubrobacterales in a karstic hypogean environment.
