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.

본 논문은 연관된 합성기로부터 생성된 음성 경고음의 모델링에 관한 실험적 연구이다. 112명의 피실험자를 대상으로 심리적-육체적인 접근방법으로 4가지의 실험이 수행 되었다. 첫 번째 실험은 함성 경고음의 위급도를 지각하는 것을 모델링하여 6개의 음성-비음성 요소들을 구분하였다. 두 번째부터 네 번째의 실험은 위급도 지각의 주관적 변화와 객관적으로 계량화 할 수 있는 파라미터를 수치화 하였다. 이 논문은 응급성의 정도를 구분하는 것이 필요한 음성 합성 경고시스템의 설계에 적용될 수 있다.

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.

본 연구는 자기자비와 폭식행동의 관계를 확인하고, 자기자비가 폭식행동에 미치는 영향이 부정정서와 부정 긴급성에 의해 매개되는지를 살펴보았다. 이를 검증하기 위해 대학생 및 대학원생 441명을 대상으로 자기자비, 부정정서, 부정 긴급성, 폭식행동을 측정하는 설문을 실시하였다. 수집한 자료는 SPSS 23.0과 AMOS 23.0 프로그램을 통해 기술통계분석 및 Pearson 상관분석, 구조방정식 모형 검증을 통해 분석되었으며, 부트스트래핑(Bootstrapping) 방법을 사용하여 간접효과의 유의성을 검증하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 상관분석 결과 자기자비, 부정정서, 부정 긴급성, 폭식행동 간 유의한 상관이 나타났다. 둘째, 자기자비와 폭식행동의 관계에서 부정정서와 부정 긴급성의 순차적 매개효과가 나타났다. 이는 대학생의 자기자비 증진이 부정정서와 부정 긴급성을 순차적으로 감소시킴으로써 폭식행동을 감소시킬 수 있음을 의미한다. 마지막으로 이러한 결과를 토대로 폭식행동의 치료에 있어 자기자비의 실제적 활용방안에 대해 제안하였다.

무선센서네트워크는 네트워크 유연함으로 인해 다양한 응용분야에 활용되고 있다. 특히 전력제한문제를 해결하기 위해 에너지 하베스팅 무선센서네트워크(EH-WSN)를 도입하여 센서네트워크의 활용범위가 더욱 넓어지고 있다. 센싱된 데이터를 목적노드까지 전송하기 위해서는 노드들의 전력을 고려한 MAC프로토콜이 중요하게 연구되고 있다. 전력상황과 데이터의 긴급성은 데이터 전송의 중요 요소이며 데이터의 긴급성과 노드들의 전력을 종합적으로 고려한 매체접근제어 프로토콜이 요구된다. 본 논문에서는 전력상황과 데이터의 긴급성에 따라 중계노드를 선택할 수 있는 매체접근제어 프로토콜을 제안하였다.

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.

에너지 하베스팅 센서네트워크에서는 노드의 전력상황을 고려하여 중계노드를 선택하는 매체접근제어 프로토콜이 요구된다. 기존의 EH-WSN (Energy harvesting wireless sensor network)의 연구들은 전력측면을 강조하다보니 센싱된 데이터의 긴급성과 같은 QoS (Quality of Service)를 크게 고려하지 못했다. 데이터의 긴급성에 따라 요구되는 전력 상황과 전송지연이 달라지도록 하여 데이터의 QoS에 맞는 매체접근이 이루어질 수 있도록 해야 한다. 중계노드의 경우 긴급하지 않은 상황에서 전력에 상관없이 모든 데이터를 중계하게 되면 막상 긴급 데이터가 발생할 경우 전력문제로 인해 지연이 크게 발생하는 상황이 생길 수 있다. 본 논문에서는 데이터의 긴급성에 따라 중계노드에 요구되는 전력상황을 다르게 설정함으로써 긴급데이터 발생 시에 발생할 수 있는 전력부족상황을 최소화하는 매체접근제어프로토콜을 설계하고 시뮬레이션을 통해 그 성능을 분석하였다. 성능분석결과 긴급데이터의 시간지연 및 신뢰성 성능이 향상됨을 확인할 수 있었다.
