This paper presents an experimental study of the factors modulating the urgency perception of voice alarm generated by concatenative synthesizers. Four experiments were conducted using psycho-physical approach in which 105 participants made magnitude estimation for urgency perception of various voice alarm stimuli. Experiment 1 identified 6 acoustic and non-acoustic factors modulating the perceived urgency of synthesized voice alarm. Experiment 2, 3 and 4 quantified the relations between the objective changes in each of the quantifiable parameters and the subjective changes in urgency perception. This research has implications for the design and implementation of synthesized voice alarm systems where urgency mapping is required.

This study examined the influence of bullying victimization on reactive aggression among upper elementary school students, and the mediating effect of victim justice sensitivity on the relationship between such victimization and aggression. It also investigated whether negative urgency moderates the influence of bullying victimization on reactive aggression. The participants were a group of 262 children (114 boys and 148 girls) who were fourth to sixth-grade students from 10 elementary schools located in Seoul, Gyeong-gi, and Daegu. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and SPSS Process Macro Model 5. The results were as follows: First, victim justice sensitivity mediated the influence of bullying victimization on reactive aggression among upper elementary school students. Second, negative urgency moderated the effect of bullying victimization on reactive aggression, whereas the impact of this was greater when the level of negative urgency was high. The results suggest that reactive aggression among upper elementary school students could be effectively decreased by preventing bullying victimization, and reducing the level of victim justice sensitivity and negative urgency.

The purpose of this study is to investigate decision making styles task management of urban homemakers. This study focuses on the following aspects: 1) to find out which variables of background variables (ie. age of couple, education of couple, duration of marriage, income, family life cycle, number of children) have effect on decision making styles & task management of urban homemakers. 2) to find out the relationships between decision making styles and task management of urban homemakers. 3) to find out independent influcene of background variables on task management. major findings are as follows; First, it is general tendency that decision making styles were human oriented in urban homemakers. Importance & Urgency of the task, age of homemakers, education of homemakers, family life cycle were significant variables to have influcence on task oriented decision making styles. Importance & urgency of task were variables to have influences on human oriented decision making styl s. Second, the tendency of dealing with task at once is the highest in the task management, on the other hand, the tendency of dealing with task in the next session is the lowest. Income is a variable to influence on dealing with task in delegation to others, education of homemaker is a variable to influence on dealing with task in next session and importance & urgency of the task and the number of children were variables to influence on dealing with task immediately. Third, human oriented decision marking style was a variable to influence on dealing with task in delegation with task in delegation to others, in the next session, and in suspending/ in neglecting. Task oriented decision making style was a variable to influence on dealing with task immediately. Fourth, The urgency of task & income were variables to have direct influence on dealing with task in delegation with task in next session, and the urgency of the task, age & education of homemaker and family life cycle were varia les to direct influence on dealing with the task immediately. The urgency & importance of the task and age of homemaker were variables to have indirect on dealing with the task urgency of task & the number of children were variables to have indirect influence on dealing with the task in suspending/in neglecting through the medium of the human oriented decision making styles.

The purpose of this study is to examine the relationship between self-compassion and binge eating and to examine the mediating effects of negative affect and negative urgency. To validify this hypothesis, 441 college and graduate students were measured self-compassion, negative affect, negative urgency, and binge eating. For the collected data, SPSS(23.0) and AMOS(23.0) were used for descriptive statistics, correlation analysis, and analyzing the structural equation model. The results of this study are summarized as follows. First, the correlation analysis showed significant correlations among self-compassion, negative affect, negative urgency, and binge eating. Second, in the relationship between self-compassion and binge eating, negative affect and negative urgency showed serial mediating effects. This means that for college and graduate students, the promotion of self-compassion can reduce binge eating behavior by sequentially reducing negative emotions and negative urgency. Finally based on these results, practical applications of self-compassion in the treatment of binge eating behavior were proposed.

Wireless sensor networks are used in various applications due to the flexibility of network. In particular, the energy harvesting wireless sensor network (EH-WSN) has been introduced to solve the power limitation problem, and the application range of the sensor network is further expanded. In order to transmit the sensed data to the destination node, the MAC protocol considering the power of the nodes has been studied. The power situation and the urgency of the data are important elements of data transmission, and a medium access control protocol that comprehensively considers data urgency and power of nodes is required. In this paper, we propose a medium access control protocol which can select relay nodes according to power situation and urgency of data.

The aim of this article is to provide major announcements within the last decade or so about possible medical emergencies in dentistry. This would be helpful to improve the knowledge on first aid suitable for dental environment. Syncope was the most common medical emergencies in dentistry. Medical emergency situations can be divided into urgency and true emergency. Urgency situations can be solved well if proper treatment is taken. However, even in an urgency, if the correct treatment is not performed, it may soon turn into an emergency. With the joint efforts of the Korean Dental Anesthesiology Society and the Korean Cardiopulmonary Resuscitation Association, dental advanced life support (DALS) has been prepared since 2015. Through 17 training experiences until January 2020, scenarios and textbooks were developed. Dentists and dental care teams need to be prepared to strengthen their competence as professionals and to increase their team-level response capabilities..

In general, the hollow jet valve, the fixed cone valve had been used for the urgency released or maintenance of the flow rate. Nowadays, the butterfly valve, the gate valve are applied in economic performance and operation maintenance more than the hollow jet valve, the fixed cone valve. However, in the case of butterfly valve, it should be required the strict application standard to the cavitation coefficient because the structural axis and disk were situated in pipe channel and the occurring the shock problem by Karman Vortex. Therefore, there were investigated the valve cavitation and accident investigation by field survey to establish the applicable extensibility of the urgency released valve as the preliminary study.

In the EH-WSN(Energy Harvesting Wireless Sensor Network), the routing protocol must consider the power condition of nodes such as residual power and energy harvesting rate. Many EH-WSN studies have emphasized the power aspect and make the urgency of sensed data less important. However, in applications such as environmental monitoring, stability and latency become more important issues than power efficiency for urgent data. In this paper, we designed a routing protocol that can set path according to data urgency. To this end, relay nodes are determined considering the urgency of date. Nodes with poor power do not participate in routing when normal data is generated, so that urgent data can be transmitted reliably with low latency. The performance of the proposed routing protocol is analyzed by computer simulation.

In the EH-WSN (Energy harvesting wireless sensor network), a MAC (medium access control) protocol is required to select a relay node considering the power status of a node. Existing EH-WSN studies emphasize the power aspect, so it does not consider the QoS like the urgency of the sensed data. The required power and transmission delay must be changed according to the urgency so that the medium access control according to the data QoS can be performed. In case of relay node, relaying data without consideration of data urgency and node power may cause delay due to power shortage in case of urgent data. In this paper, we designed a MAC protocol that minimizes the power shortage that can occur during emergency data generation. For this, relay node requirements are set differently according to the urgency of data. The performance was analyzed through simulation. Simulation results show the reduced latency and improved reliability of urgent data transmission.
