In the context of China's economy shifting to a high-quality development stage, how to promote the performance of manufacturing enterprises through new quality productive forces (NQPF) has become an important topic. Based on the multi-period panel data of listed companies in China's manufacturing industry, this paper uses the panel vector autoregression (PVAR) model to systematically explore the two-way interaction mechanism between new quality productive forces and enterprise performance (represented by TobinQ) from a dynamic perspective. The empirical results show that the study found that the new quality productive forces has a significant positive impact on enterprise performance, especially after controlling for individual differences and time factors of enterprises. At the same time, the research results also show that the PVAR dynamic panel model based on system GMM further reveals the temporal interaction mechanism between the two. The lagged term of Nqpf significantly positively affects TobinQ, indicating that the new quality productive forces has a continuous driving force on enterprise performance; while the lag of TobinQ has a negative feedback on Nqpf, indicating that the short-term improvement of enterprise performance may inhibit the investment in new quality productive forces, reflecting a certain reverse dynamic mechanism. This finding emphasizes the need to pay attention to the dynamic balance between enterprise input and output in policy making. The impulse response analysis shows that the TobinQ shock produces a positive response on the new quality productivity (Ngpf) from period 0 to period 1, but falls below zero and enters the negative range from period 1, remains negative for several periods, and finally returns to a stable level. This finding remains insufficiently statistically significant. The impact of Nqpf on TobinQ showed a significant positive impact in the previous periods. A positive shock to Nqpf will significantly increase TobinQ in periods 1–2, reach a peak in period 2, and then decline. Within a certain range, the improvement of New Quality Productive Forces will help improve corporate performance and have a certain incentive effect. The variance decomposition results show that TobinQ in the early stage is mainly explained by its own influence, but the explanation rate of NQPF in the 8th period reaches 11.8%, showing its long-term driving effect on the market performance of enterprises; and the change of NQPF is almost completely driven by itself, reflecting its exogenous characteristics. This study not only verifies the hysteresis and long-term impact of new quality productive forces on enterprise performance from an empirical level, but also reveals the interactive relationship between market and innovation. The research results provide theoretical support for manufacturing enterprises to formulate innovation strategies and optimize resource allocation, and also provide targeted suggestions for macro policy makers to promote high-quality development from the enterprise level in the process of China's modernization.

Purpose: This study aimed to examine the relationship between future core nursing competencies and key variables, identifying factors influencing these competencies among senior nursing students. Methods: This cross-sectional study included 150 third- and fourth-year nursing stu- dents in South Korea. Based on King’s Dynamic Interaction System Model, perceived work value and individual innovative behavior were categorized as personal systems, interpersonal competence as an interpersonal system, and adhocracy culture as a social system. Participants completed self-reported online questionnaires to assess factors influ- encing future core nursing competencies. Results: Hierarchical multiple regression analysis identified interpersonal competency (β=0.32, p=.012) and adhocracy culture (β=0.23, p=.010) as significant predictors of future core nursing competency explaining 30.9% of the variance. Conclusion: Enhancing future core nursing competency among senior nursing students requires continuous education and counseling programs to strengthen interpersonal competency. Establishing an adhocracy culture involves recognizing creative ideas, fos- tering open communication for freely expressing ideas, and encouraging innovation. Therefore, developing interpersonal competence and promoting an adhocracy culture is essential for improving future core nursing competency in senior nursing students.

Therefore this study concluded that the Art activity program with dynamic interaction is effective to improve self-esteem and learning motivation for children with learning disability.

본 논문에서는 움직이는 물체 표면에 실시간으로 영상을 투사하고 3D 콘텐츠를 제어하는 프로젝션 맵핑 기반 상호작용 시스템을 제안한다. 동적 장면에서의 프로젝션 맵핑은 이동 표면의 인식 후 투사에 따른 시스템 지연 문제가 발생한다. 제안 기법은 깊이 카메라-프로젝터 보정을 통해 왜곡을 보정하고 Kalman Filter, Hysteresis 기반 이중 경계기법을 통해 지연 문제를 해결하였다. 또한, 물체의 움직임을 추적함으로써 배경에 표시되던 영상을 전경 패널로 전환하고 물체 동작에 따라 애니메이션 및 콘텐츠 흐름을 변화시킨다. 프로젝션 지연 시간은 수십 밀리초 수준이었으며 'Magic Cube' 시범 콘텐츠를 통해 직관적인 상호작용과 높은 몰입감을 확인하였다.

In this paper, we propose a projection mapping-based interactive system that projects images onto the surface of moving objects in real time and controls 3D content. Projection mapping in dynamic scenes suffers from system latency due to the recognition of moving surfaces and subsequent projection. The proposed technique compensates for distortion through depth camera-projector calibration and addresses the latency issue through a Kalman filter and hysteresis-based double-edge technique. The proposed technique compensates for distortion through depth camera-projector compensation and tracks object movement, shifting images from the background to the foreground, and altering animation and content flow based on object movement. Projection latency was measured in tens of milliseconds, and intuitive interaction and high immersion were demonstrated through the "Magic Cube" demonstration content.

People lead a humane life through interaction with others. The purpose of this study was to illustrate the effects on an art program led by normal peer children to middle grade elementary children, and to examine how much do the children improve the social interaction skills. A mentally retarded child and a child with attention deficit hyperactivity disorder who were classified as children with developmental disorder were participated for this study. After the children were selected by the class teachers’ recommendation, they received a peer teaching and training program and participated in a dynamic art activity intervention led by normal peer children. A ABAB design was utilized to compare causal relation between independent variables and dependent variables. Each session was held at the art room for 40 minutes and the children’s art activities were videotaped for 20 minutes. These data were recorded using the same interval recording method of 15 seconds(recording after 15 seconds’ observation). This study concluded that the peer-based dynamic arts activity was effective to improve social interaction for children with developmental disabilities.

We aimed to identify personal-interpersonal-social factors influencing Person-Centered Care Competence (PCCC) of senior grade nursing students based on King's dynamic interaction system model. The data were collected using online based questionnaires that contained items on ethical sensitivity, peer group care interaction, interpersonal competence, social support and PCCC. The participants were 242 4th grade nursing students who had undergone clinical practicum. The data were analyzed using descriptive statistics, T-test, ANOVA, Pearson's correlation coefficients, and Multiple regression analysis with the SPSS 26.0. In the multiple regression analysis, interpersonal competence(β =0.42, p <.001) and social support(β=0.29, p <.001) were statistically significant factors that explained 44.1% of PCCC(F=23.77, p <.001). This study is significant in that we identified the factors affecting the Person-centered Care competence based on King’s conceptual framework. This study could provide basic data for the development of an intervention program to improve PCCC of senior nursing students.

기존 비디오 게임은 사전 정의된 스크립트와 정적인 캐릭터 관계 모델로 인해 상호작용 과 몰입감에 한계가 있다. 최근 대규모 언어 모델(LLM)이 대안으로 떠올랐으나, 생성된 서 사와 게임 내부 데이터가 단절되는 문제가 여전히 존재한다. 이에 본 연구는 Unity 엔진, LLM, 게임 서버 플랫폼을 통합하여 캐릭터 데이터가 서사를 생성하고, 그 결과가 다시 데 이터베이스에 반영되는 '순환형 동적 스토리텔링 시스템'을 제안한다. 실험 결과, 캐릭터 성 향에 따른 차별화된 서사 생성 및 관계도의 실시간 DB 동기화를 확인하였다. 본 시스템은 기존 스크립트의 경직성을 극복하고 무한히 확장 가능한 개인화된 게임 경험을 제공한다.

Traditional video games suffer from limited interactions due to predefined scripts and static relationship models. While Large Language Models (LLMs) offer generative freedom, a disconnect remains between AI-generated narratives and internal game data. To address this, we propose a cyclical dynamic storytelling system integrating Unity, an LLM, and a game server. In this system, character attributes drive narrative generation, and the outcomes are continuously synchronized back to the game's database. Experiments confirmed that differentiated narratives were generated based on character alignments, with real-time updates to their affinity data. This approach overcomes the rigidity of traditional scripts, offering a highly personalized gaming experience.

In the transitional period of Urbanization, the urban landscape and its aesthetical experience became one of research priorities.

It is a dynamic interactive information system of urban landscape based on Web technologies. This article described the structure and functions of the system, explained design methods of the database and application. The construction and application of the system can integrate landscape information of the transitional period of Urbanization, such as item information, engineering information, education information and artistic information, offer a human-machine interactive communication platform based on P2P mode (point-to-point). It will become innovative power for the development of urban landscape industry.

Human-computer interaction (HCI) has great potential for applications in many fields. A HCI method has been developed based on audio-visual perceptive features and dynamic interactive pooling. A mode analysis based fusion strategy is proposed to fuse the interactive responses from audio-visual modalities especially for the case there are deviations from the modalities at the same time. The developed approach can be applied with a better performance even in single modal with multiple interactive users in the scenario. The users in the scenario are endowed with a fair chance to perform HCI by their interactive priorities no matter how many modalities used, and the interactive authority and priority are updated dynamically according to the variation of HCI content. The scenario and multiple users altogether are regarded as a dynamic HCI pooling. The diversity of interactive habits among multiple users is considered in an ordinary hardware from a crowded scene without any hypothesis for the scenario contents in advance. The pooling is updated dynamically to meet the user demands with the most intentions preferentially. Comparative study with state-of-the-arts has indicated the superior performance of the proposed method.

This paper analyzes the simultaneous linkages between remittances and macroeconomic variables using a panel vector autoregression (PVAR) for 33 Sub-Saharan Africa (SSA) countries from 1973 to 2011. We document the strong impact of inflation on explaining remittances to SSA. Approximately 20% of the variance in remittances is attributed to un- expected inflation shocks. This supports the notion that remittances compensate local incomes. This paper also documents a strong positive impact of remittances on growth in SSA. These results demonstrate that remittances can aid in over- coming liquidity constraints in nations with poor financial institutions. Our findings shed light on the important role of remittances in explaining macroeconomic variability in SSA.

Subject of the paper is a particular configuration of overhead line, in which noise barrier structure is used as supports of the catenary instead of standard poles. This configuration is foreseen in case the noise barrier position is in conflict with the poles location. If the catenary is supported by the noise barrier, the motion that the latter undergo due to wave pressure associated to train transit is transmitted to the overhead line, so that potentially it influences the interaction between the catenary itself and the pantograph of the passing train. The paper focuses on the influence of such peculiar configuration on the quality of the current collection of high speed pantograph, for single and double current collection. The study has been carried out first with an experimental investigation on the pressure distribution on noise barrier, both in wind tunnel and with in-field tests. Subsequently a numerical analysis of the dynamics of the barrier subjected to the wave pressure due to train transit has been carried out, and the output of such analysis has been used as input data for the simulation of the pantograph-dynamic interaction at different speeds and with front or rear pantograph in operation. Consideration of structural modifications was then highlighted, in order to reduce the influence on the contact loss percentage.

Along with the E-Business’s swift devel opment, E-Business is getting more and more important in economic developm ent’s function. Also, E-Business is the first productive point in the developme nt of economy and a new economic mo de to produce value. The purpose of this empirical study is to explore the dy namic interaction between E-Business and economic growth in China. The re ason is that being a completely new pa ttern of business operation, E-Business is giving a great lash to traditional econ omy in China. This study applies annu al data from 2000 to 2016. The Cobb-D ouglas production function is introduced into this paper. The theoretical framew ork is established, which is based on this function with the E-Business. The Augmented Dickey-Fuller test, cointegr ation test, Granger causality test, impul se response function and variance dec omposition are used to analyze the dy namic interaction between E-Business and economic growth. The empirical a nalysis is conducted under the vector autoregression model. The empirical r esults indicate that there is a dynamic interaction between the E-Business and the economic growth in China. More sp ecifically, the E-Business and economic growth move in the same direction. In other words, an increase in the E-Busi ness will result in an increase in the real GDP; an increase in the real GDP will also lead to an increase in the E-Bu siness. However, the contribution of EBusiness on economic growth is less than that of economic growth on E-Bus iness.

The paper seeks to explain the reasons and motivation behind the ongoing maritime territorial disputes in East Asia, focusing on Dokdo/Takeshima as well as Senkaku/Diayou. First, it lays out the background of the region’s emotion-filled politics by utilizing the symbolic politics framework. Next, the paper shows that the main reason for Tokyo’s aggressive and headstrong response to the territorial dispute is Japan’s perception of its status in the region declining precipitously. Strong and antagonistic nationalism in China is another concern. The changing balance of power in the region due to the rapid rise of China makes the situation more complicated. Thus, interwoven challenges of history and politics and complex dynamics of identity and interests make the establishment of a peaceful region extremely difficult. I conclude the paper by providing some policy options for Seoul including its imperative need to improve the operational capability of the Republic of Korea (ROK) Navy and Air Force.

To regulate primary coolant flow in the Advanced Test Reactor (ATR), a butterfly valve was installed between the primary coolant pumps and the reactor core. If the mechanical connection between the valve's disk and its shaft ever fails, the disk will rotate freely. Rapid disk rotation may induce pressure surges that could damage upstream pipes. In the present work, the rotational trajectory and pressure evolution during a disk free-rotation scenario were analyzed via the dynamic fluid-body interaction (DFBI) approach in STAR-CCM+, with the movement of a solid being driven by the forces and moment/torque imposed by its surrounding fluid. Assuming a large initial opening angle, the disk accelerates slowly, but swiftly passes the closed position. As a result of the sudden valve closure, a pressure surge occurs in the upstream pipes, exceeding their maximum allowable pressure. Furthermore, the disk does not stabilize at the closed position but continually oscillates due to the unsteady nature of the coolant flow. Because of the significant and continuous water hammer effect, a fix to the butterfly valve is being implemented to prevent rapid valve closure due to failure at the valve's disk/shaft mechanical connection.

The regional-scale transient groundwater-river interaction model is developed to gain a better understanding of the regional-scale relationships and interactions between groundwater and river system and quantify the residual river flow after groundwater abstraction from the aquifers with climate variability in the Waimea Plains, New Zealand. The effect of groundwater abstraction and climate variability on river flows is evaluated by calculating river flows at the downstream area for three different drought years (a 1 in 10 drought year, 1 in 20 drought year, and 1 in 24 drought year) and an average year with metered water abstraction data. The effect of future water demand (50 year projection) on river flows is also evaluated. A significant increase in the occurrence of zero flow, or very low flow of 100 L/sec at the downstream area is predicted due to large groundwater abstraction increase with climate variability. Modeling results shows the necessity of establishing dynamic cutback scenarios of water usage to users over the period of drought conditions considering different climate variability from current allocation limit to reduce the occurrence of low flow conditions at the downstream area.
