This study aims to determine the influential factors on market share of electric vehicles through panel data analysis based time series from 2011 2015 in 31 countries. We selected five significant independent variables that are expected affect vehicle adoption literature review. The econometric model this suggests relative price compared internal combustion engine vehicle, driving range, and number models available markets correlated vehicles. On other hand, relationship between recharging...
Governments around the world are planning to ban sales of vehicles running on petroleum-based fuels as an effort reduce greenhouse gas emissions, and electric surfaced a solution decrease pollutants produced by transportation sector. As result, wireless power transfer technology has recently gained much attention convenient practical method for charging vehicles. In this paper, patent analysis is conducted identify emerging vacant areas transfer. Topics first extracted from patents text...
The purpose of this research was to derive promising technologies for the transport hydrogen fuel cells, thereby supporting development and policy presenting directions investment. We also provide researchers with information about technology that will lead field in future. Hydrogen energy, as core carbon neutral green is a major issue changing future industrial structure national competitive advantage. In study, we derived at cell transportation using published US patent paper databases...
The rapid advancement of digital technologies has fundamentally changed the competitive dynamics logistics industry. For players in industry, digitization become an unavoidable situation to achieve survival and sustainable competitiveness. A technology strategy is essential for digitization, identifying opportunities threats development through trend exploration important strategy. In addition, enable implementation strategy, it necessary detect change search that expected have a practical...
This study compares time-based and quantity-based consolidation strategies within the Vehicle Routing Problem (VRP) framework to optimize supplier profitability logistical efficiency. The model consolidates deliveries at fixed intervals, offering predictable routes, reduced customer wait times, cost efficiency in stable markets. Conversely, dynamically adjusts delivery volumes meet fluctuating demand, providing flexibility dynamic environments but potentially increasing long-term costs due...
Collaborative information sharing in the maritime logistics supply chain is essential for achieving efficiency, sustainability, and resilience. However, numerous barriers hinder effective among key stakeholders, including port operators, shipping companies, trucking firms. This study conducts an empirical analysis involving surveys interviews with industry experts South Korea, applying Fuzzy Analytical Hierarchy Process (Fuzzy AHP) to identify prioritize critical collaborative...
In this article, we present a wearable intelligence device for activity monitoring applications. We developed and evaluated algorithms to recognize physical activities from data acquired using 3-axis accelerometer with single camera worn on body. The recognition process is performed in two steps: at first the features defining human are measured by sensor image embedded device. Then, corresponding determined applying SVM classifier. computes correlation between axes magnitude of FFT other an...
The increasing density of urban populations has spurred interest in utilizing underground space. Underground logistics systems (ULS) are gaining traction due to their effective utilization this space enhance spatial efficiency. However, research on technological advancements related fields remains limited. To address gap, we applied a data-driven approach using patent data the ULS develop technology roadmap for field. We employed Latent Dirichlet Allocation (LDA), machine learning-based...
An electric motor is a device that changes electrical energy into mechanical for railway vehicles. When developing the motor, it used to be developed simply structures or control methods of itself without considering convergence with other devices technologies. However, as vehicles become more advanced, technology development through technologies spreading. Therefore, based on patent data related motors applied vehicles, this research aims carry out technical forecasting establishing and (R...
Overcrowding of emergency department (ED) has put a strain on national healthcare systems and adversely affected the clinical outcomes critically ill patients. Early identification patients prior to ED visits can help induce optimal patient flow allocate medical resources effectively. This study aims develop ML-based models for predicting critical illness in community, paramedic, hospital stages using Korean National Emergency Department Information System (NEDIS) data. Random forest light...
This paper aims to analyze the influence of technological diversification on a firm’s innovation capabilities and investigates effect various strategies financial performance in technology-oriented environment. We employ entropy measurement calculate with 2095 patents, which are applied from years 2009 2011 by 507 firms that have participated Korean government Information Technology (IT) Research Development (R&D) supporting programs. In our framework, firm should not diversify among...
We explore the impact of research and development (R&D) on sales growth rate with firm-specific factors under Korean pharmaceutical industry structure using listed Korea company data from 2007 to 2018 quantile regression technique. find that R&D intensity has a positive effect firm while scale negative at upper quantile, whereas result is opposite lower quantile. Firm size mixed relationship thus Gibrat’s law rejected in industry. age which shows consistent previous young firms grow...
In this study, we identify and forecast promising railway static inverter technologies the technology taxonomy using patent data analytics.
