Investigating Driver Preferences for Traffic Information Using Digital Signage and Road Surface Holograms

This study investigates road users' information preferences to enhance traffic information provision strategies. Traditional road signs primarily convey static information like speed limits and restricted areas. However, smart street poles now offer the capability to collect real-time road conditions and deliver dynamic traffic updates promptly. Leveraging these smart poles allows for more effective and tailored information delivery strategies. The research examines three types of media for information dissemination: digital signage, road surface hologram, and a combination of both. Additionally, it surveys road users' preferences for information delivery methods, including text, graphics, or a mixture, based on the type of information. Conjoint analysis of 220 responses reveals essential attributes influencing users when they receive information. The findings indicate that a majority of road users prefer a blend of digital signage and road surface holograms, with a notable preference among younger individuals for digital signage. For road surface holograms, the favored approach involves a mix of text and graphics. This study lays the foundation for user-centric information strategies, offering insights into tailoring approaches based on the type of information and user preferences.

메타버스를 활용한 한국·싱가포르 국제교류 수업의 실천

This study aims to practice international exchange classes between Korea and Singapore using the metaverse and to seek the meaning of learning and encounters in the metaverse space. As a result of the elements of the metaverse to the autonomous cooperative learning model, discussion between learners on topic research and presentation methods was more emphasized than in conventional classes. Since the introduction of data in the metaverse is mainly done in the form of web postings, effective information delivery strategies that take this into account have been discussed a lot. In addition, since the entire learning- sub-topic- mini-subject learning spaces are separated and connected, communication between group members was greatly required to create a harmonious space composition with overall learning while maintaining the individuality of the subject selected by the learner. As a result of class execution, in terms of learning, the strengthening of learning accountability due to the occupation of learning space, the creation of a two-sided space of connection and exclusion, and the autonomy of learning between exploration and wandering were meaningfully observed. As for the dimension of meeting, it was possible to confirm the aspects of hospitality experienced as hosts and guests and the new ideas of hospitality discovered by the learners.

Participation of university community members in Health Promoting University (HPU) initiatives.

Several universities around the world have adopted the settings approach to health to create a Health Promoting University (HPU) initiative. Health promoting initiatives are built on the values of health promotion, with participation being one of the most important. Despite the above, there is little information on how university community members participate in HPU initiatives. This study aims to describe the participation of university community members in HPU initiatives in universities around the world. An online questionnaire was sent to representatives of universities that have implemented a HPU initiative. The questionnaire inquired about the level and nature of participation of university community members (students, professors, and administrative/technical staff) at different levels. Three levels of participation ranged from lower to higher levels were considered: (a) information delivery strategies; (b) consultation strategies and (c) involvement in design, planning and decision-making processes. At least the 50% of the universities implemented strategies so that all the members of the community could participate at all levels. Information delivery strategies were the most often used, with students being the main target group. Consultation strategies were aimed mainly at students and professors, whilst professors participated most actively in the design, planning and decision-making. Different participation strategies are used in the HPU initiatives. Information delivery strategies, which represent the lowest level of participation, were the most often reported. Higher levels of participation were less used in the HPU initiatives. HPU initiatives should seek for strategies to provide more high-level participation to all university community members.

The Effect of Information Acquisition Ability on Farmers’ Agricultural Productive Service Behavior: An Empirical Analysis of Corn Farmers in Northeast China

Agricultural productive services are an important means to achieve effective allocation of regional resources and play an important role in ensuring food security and improving farmers’ welfare. However, the development process of agricultural productive services still faces problems such as large differences in service levels in different segments and low participation rates in the full service. In order to investigate the influential paths of the low participation rate of farmers in the full-service process, this study takes maize farmers in northeast China as the research object. Based on 937 survey data from six cities in three northeastern provinces, we used the Item Response Theory (IRT) model to measure farmers’ information acquisition ability and constructed the Heckman two-stage model and the IV-Heckman model to analyze the logical framework of “information acquisition ability—farmers’ choice of productive agricultural services”. The main findings are as follows: firstly, the more channels there are, the stronger the farmers’ channel internalities; the higher the degree of channel differentiation, the stronger the farmers’ channel internalities. Second, after addressing the sample selection bias and endogeneity, there is a small rise in the facilitation effect of information acquisition ability on farmers’ productive agricultural service behavior. Third, this facilitation effect is achieved through farmers’ perceived usefulness of productive agricultural services, and the mediating effect of perceived ease of use is not significant. Therefore, fostering farmers’ self-perceptions and optimizing information delivery strategies are effective ways to promote farmers’ choice of agricultural productive services and to facilitate the modernization of Chinese agriculture. In general, this study helps to reveal the theoretical mechanism of farmers’ information asymmetry, and provides empirical evidence for how to promote the development of agricultural productive services.

Distributed Event-Triggered Optimal Control Method for Heterogeneous Energy Storage Systems in Smart Grid

Increasing implementation of energy storage systems (ESS) is an available way to mitigate the fluctuation of renewable energy sources (RES) in smart grid. This paper proposes distributed control strategies without/with event-triggered information delivery for a group of heterogeneous energy storage systems (HESS) with different parameters such that the power fluctuation of renewable generation and load variation can be smoothed, meanwhile ensuring power and energy sharing among various ESS. To mitigate the impacts of parameter differences in HESS, a weighted control matrix is designed, and the method of deriving optimal feedback control gain is designed with the help of Riccati control theory. Aiming at reducing communication burdens meanwhile guaranteeing system performance, an event-triggered information delivery strategy without Zeno behavior is introduced to the distributed control method. Convergence and stability of the proposed methods are verified by rigorous mathematical analysis. Simulation studies are conducted to verify the effectiveness of the proposed method. The results show that the proposed method can achieve the state of charge (SoC), the state of temperature (SoT) and the state of energy (SoE) balance of HESS, proportional power sharing and power tracking objectives, even if the states of HESS are interfered by random disturbances.

A dynamic road incident information delivery strategy to reduce urban traffic congestion

Advanced information and communication technologies can be used to facilitate traffic incident management. If an incident is detected and blocks a road link, in order to reduce the incident-induced traffic congestion, a dynamic strategy to deliver incident information to selected drivers and help them make detours in urban areas is proposed by this work. Time-dependent shortest path algorithms are used to generate a subnetwork where vehicles should receive such information. A simulation approach based on an extended cell transmission model is used to describe traffic flow in urban networks where path information and traffic flow at downstream road links are well modeled. Simulation results reveal the influences of some major parameters of an incident-induced congestion dissipation process such as the ratio of route-changing vehicles to the total vehicles, operation time interval of the proposed strategy, traffic density in the traffic network, and the scope of the area where traffic incident information is delivered. The results can be used to improve the state of the art in preventing urban road traffic congestion caused by incidents.

SCI peer health coach influence on self-management with peers: a qualitative analysis.

A process evaluation of a clinical trial. To describe the roles fulfilled by peer health coaches (PHCs) with spinal cord injury (SCI) during a randomized controlled trial research study called 'My Care My Call', a novel telephone-based, peer-led self-management intervention for adults with chronic SCI 1+ years after injury. Connecticut and Greater Boston Area, MA, USA. Directed content analysis was used to qualitatively examine information from 504 tele-coaching calls, conducted with 42 participants with SCI, by two trained SCI PHCs. Self-management was the focus of each 6-month PHC-peer relationship. PHCs documented how and when they used the communication tools (CTs) and information delivery strategies (IDSs) they developed for the intervention. Interaction data were coded and analyzed to determine PHC roles in relation to CT and IDS utilization and application. PHCs performed three principal roles: Role Model, Supporter, and Advisor. Role Model interactions included CTs and IDSs that allowed PHCs to share personal experiences of managing and living with an SCI, including sharing their opinions and advice when appropriate. As Supporters, PHCs used CTs and IDSs to build credible relationships based on dependability and reassuring encouragement. PHCs fulfilled the unique role of Advisor using CTs and IDSs to teach and strategize with peers about SCI self-management. The SCI PHC performs a powerful, flexible role in promoting SCI self-management among peers. Analysis of PHC roles can inform the design of peer-led interventions and highlights the importance for the provision of peer mentor training.

Efisiensi Energi Sistem Komunikasi Kooperatif Multi-relay Quantize and Forward Berdasarkan Pemilihan Relay

Currently, the increasing energy consumption is a global issue. Information technology and telecommunication industry is one of the areas with the largest energy consumption. The growth of mobile data users is an issue and the biggest challenge for the future. The cooperative wireless communication system has been the focus of research as one of the information delivery strategy with more efficient energy consumption. Energy efficiency in the cooperative wireless communication system can be improved by using a relay between base station and user device, where the distance between base station and user can be shortened, thus, the energy transmission can be minimized. Relay mechanism can be built by utilizing the protocol in the cooperative communication system, such as amplify and forward (AF), decode and forward (DF), and quantize and forward (QF). Relay-selection is an important issue in a cooperative wireless communication system that can reduce energy consumption at the system level. This study analyzes energy efficiency of multi-relay QF cooperative communication for line-of-sight (LOS) and non-line-of-sight (NLOS) environment based on relay selection strategies: reactive and proactive relay selection. A computer simulation is conducted based on a system model and mathematical analysis. Energy efficiency is calculated based on power consumption of signal transmission and observed in the distance between the source, relay, and destination. Simulation result shows that multi-relay QF networks with relay selection consume lower energy than without relay selection, hence, the energy usage in the relay selection networks is more efficient. Moreover, the strategy of proactive relay selection provides low energy consumption and high energy efficiency compared to the reactive relay selection strategy.

Cancer Information-Seeking Practices Among the Hispanic Population: Data From the Health Information National Trends Survey 2007.

Hispanic people are less likely to seek cancer information and experience more health care barriers than non-Hispanic people. The purpose of this work was to identify cancer information-seeking practices among U. S. Hispanic adults and identify demographic characteristics associated with information selected. Data from 622 Hispanic participants in the Health Information National Trends Survey 2007 were analyzed. Results of this study indicated that the leading sources of cancer information came from the Internet (47%, n = 105), followed by health care providers (26%, n = 60). As educational level increased, Internet use for cancer information-seeking increased from 20.7% (n = 6) to 60.6% (n = 40). These data indicate a necessity to improve information delivery strategies tailored to this group.

Food allergic consumers' preferences for labelling practices: a qualitative study in a real shopping environment

AbstractFood allergy is a chronic disease that can only be managed through avoidance of problematic proteins in the diet. Inappropriate communication about food allergens can cause stress and insecurity, which may have a negative impact on quality of life. The aim was to investigate whether information provided through current labelling practices meets the need of food allergic consumers. A total of 40 participants (20 adult food allergy suffers and 20 parents of food allergic children) were recruited from two different European countries (Greece and The Netherlands), and interviewed while shopping in a supermarket. Participants were asked to purchase 15 potentially problematic food items as if for their own household. Their information search behaviour was observed, and participants were questioned about their preferences for food allergen information provision. Participants reported experiencing problems associated with current food allergy information provision. It was reported that inappropriate use of fonts, colours and languages, application of precautionary labelling and lack of harmonization in labelling practices across countries can cause (un)necessary dietary restrictions for food allergic consumers. Research is needed to investigate the feasibility and implementation possibilities for new information delivery strategies and amendments to existing European labelling policy.
