Recent research has been actively carried out on systems that want to optimize resource utilization by analyzing the intended behavior and pattern of behavior of objects (users, consumers). A service system that applies information about an object"s location or behavior must include a location trigger processing system for tracking an object"s real-time location. In this paper, we analyze design problems for the implementation of a context-awareness based location trigger system, and present system models based on analysis details. For this purpose, this paper introduces the concept of location trigger for intelligent location tracking techniques about moving situations of objects, and suggests a mobile agent system with active rules that can perform monitoring and appropriate actions based on sensing information and location context information, and uses them to design and implement the location trigger system for context-awareness based location services. The proposed system is verified by implementing location trigger processing scenarios and trigger service and action service protocols. In addition, through experiments on mobile agents with active rules, it is suggested that the proposed system can optimize the role and function of the application system by using rules appropriate to the service characteristics and that it is scalable and effective for location-based service systems. This paper is a preliminary study for the establishment of an optimization system for utilizing resources (equipment, power, manpower, etc.) through the active characteristics of systems such as real-time remote autonomous control and exception handling over consumption patterns and behavior changes of power users. The proposed system can be used in system configurations that induce optimization of resource utilization through intelligent warning and action based on location of objects, and can be effectively applied to the development of various location service systems.

The purpose of this study is to evaluate the carbon point system from consumers` point of view, and contribute to proposing ways to establish the carbon point system as a sustainable system by discussing what needs to be improved. It analyzed the differences between carbon point system participants and non-participants in terms of eco-awareness and environment actions, participants`` satisfaction with and use of the carbon point system, and the characteristics of non-participants. This study also tried to understand how eco-awareness, environment actions, and consumers`` awareness of the carbon point system affected participation in the carbon point system. The results showed that there was no significant difference between participants and non-participants in terms of eco-awareness and environment actions except for the greater importance of environmental conservation than economic development, and self-assessment of the level of eco-awareness. It was revealed that participants were more aware of the carbon point system, but the level did not meet expectations. As for satisfaction with the operation of the system, consumers living in larger homes were more satisfied. It turned out that non-participants were not well aware of the carbon point system, and they said that PR and educational programs would need to be invigorated in order to raise the participation ratio. Lastly, the more aware of the carbon point system they are, the more likely they are to participate in the carbon point system.

적응형 정속 주행 시스템에 대한 운전자 신뢰와 도로 혼잡도가 작업부하 및 상황인식에 미치는 효과

권순찬,이재식 한국감성과학회 2020 감성과학 Vol.23 No.2

Using driving simulation, this study investigated the effects of driver's trust in the adaptive cruise control (ACC) system and road density on driver's workload and situation awareness. The drivers were allocated into one of four experimental conditions manipulated by ACC system trust level (trust-increased vs. trust-decreased) and road congestion (high vs. low). The workload and situational awareness of the participants were measured as dependent variables. The results showed followings. First, trust-decreased group for the ACC system had significantly lower trust scores for the system in all of the measurement items, including reducing the driving load and securing safe driving due to the use of this system, than the trust-increased group. Second, the trust-decreased group showed a slower reaction time in the secondary tasks and higher subjective workload than trust-increased group. Third, in contrast, the situational awareness for the driving situation was significantly higher in the trust-decreased group than trust-increased group. The results of this study showed that the driver's trust in the ACC system can affect the various information processing performed while driving. Also, these results suggest that trust in the user's system should be considered as an important variable in the design of an automated driving assistance system. 본 연구에서는 운전 시뮬레이션을 이용하여 적응형 정속 주행(adaptive cruise control: ACC) 시스템에 대한 운전자의 신뢰 및 도로 혼잡도가 운전자의 작업부하와 상황인식에 미치는 효과를 알아보았다. ACC 시스템에 대한 운전자의 신뢰는 ACC 시스템이 정상 작동하는 조건과 시스템이 오작동하는 조건을 통해 신뢰상승 집단과 신뢰감소 집단으로 구분하였다. 도로 혼잡도는 운전자 차량 주변의 차량 수로 수준을 조작하였다. ACC 시스템에 대한 신뢰와 도로 혼잡도 를 달리한 네 가지의 실험 조건 각각에 대해 운전자들의 작업부하와 상황인식을 측정하였다. 본 연구의 결과를 요약하면 다음과 같다. 먼저 ACC 시스템에 대한 신뢰감소 집단은 신뢰상승 집단에 비해 이 시스템의 사용으로 인한 운전부담 경감이나 안전운전 확보 등을 포함한 측정 항목 모두에서 시스템에 대한 신뢰 점수가 유의하게 더 낮았다. 둘째, ACC 시스템에 대한 신뢰감소 집단은 신뢰상승 집단에 비해 이차과제에서 더 느린 반응시간을 보였고, 시스템 사용에서의 주관적인 작업부하 수준도 더 높게 평정하였다. 셋째, 이와는 대조적으로 운전자들의 운전상황에 대한 상황인식은 ACC 시스템 신뢰감소 집단이 신뢰상승 집단보다 유의하게 더 우수하였다. 본 연구의 결과들은 ACC 시스템에 대한 신뢰가 운전 중에 수행하는 다양한 정보처리에 영향을 미칠 수 있음을 보였는데, 이것은 자동화된 운전보조 시스템의 설계에서 사용자의 시스템에 대한 신뢰가 중요한 변인으로 고려되어야 한다는 것을 시사한다.

이승호,백승령 한국경영과학회 2020 한국경영과학회지 Vol.45 No.2

This study aims to identify the effects of the technological and individual characteristics of army tactical command information system (ATCIS) on situation awareness and decision making, under the concept of network-centric modern warfare. On the basis of adaptive structuration theory and situation awareness theory, we consider the technological characteristics of the system as real time, convergence, and information visualization effect. System experience and IT capability are used as the variables for individual characteristics. We hypothesize that these variables affect users’situation awareness which leads to their decision making. A field survey is administered to the Republic of Korea (ROK) Army officers who have experienced using the system for more than six months. Survey results show that excluding real time, convergence and information visualization effect influence users’situation awareness. Users’ system experience and IT capability also increase situation awareness. The higher the degree of users’ situation awareness, the better their decision making. Theoretically, this study implies thatthe effects of the technological and individual characteristics of ATCIS on situation awareness must be investigated. Practically, our study guides and suggests development plans for the ATCIS to the ROK Army.

The purpose of this study was to analyze consumers' awareness and satisfaction of open price system. Questionnaire survey was conducted from 3 September to 14 September 2011. We have surveyed 200 consumers who were living in Cheongju area. Major findings are as follows. First, consumers were not aware about open price system very well. The mean of the objectives and expected effects of open price system was 2.38. It means that many consumers when it comes to the open price system does not have the proper recognition was considered. Second, there was not big changes for consumers' information search behavior after execution the open price system. Third, consumers' satisfaction mean(m=2.32) of open price system was lower than dissatisfaction mean(m=3.40) of that. The main reason of dissatisfaction due to inconsistent pricing confusion was investigated. Fourth, there were statistic differences in open price system awareness and consumer behavior by consumers' socio-economics characteristics such as age, education, income, occupation, etc. Finally, consumers' satisfaction of open price system was influence by information search cost, product or brand image. On the other hand, consumers' dissatisfaction was only influence by open price system awareness.

Lokesh. M. R,Y.S. Kumaraswamy 보안공학연구지원센터 2014 International Journal of Multimedia and Ubiquitous Vol.9 No.11

Disturbances to a system are inevitable. Resilience is thus utmost necessary to the system as it has to respond to the stresses and disturbances to keep the system stable. Cyber physical systems are physical engineered systems whose operations are monitored, coordinated, controlled and integrated by a computing communication core which is expected to transform the physical world around us. This paper proposes an autonomic self healing architecture for improving resiliency in cyber physical system using autonomic computing self management properties. This is a layered architecture in which each stage has a mechanism to collect state information of the system and monitor the system behavior, if the performance of the system is degraded in comparison to the normal level, self healing module is activated to facilitate recovery from damaged state and restoring to normal state, thereby achieving resilience in the system.

이승신 ( Seung Sin Lee ) 대한가정학회 2016 Human Ecology Research(HER) Vol.54 No.1

Consumer anxiety about food safety is increasing, and the ability to make an accurate assessment is inadequate due to the lack of food safety information. This research focuses on relations among main variables, such as food hazard awareness, food apprehension, food safety information awareness, and food safety management system evaluation. In addition, to the moderating effects of food safety information awareness between food hazards awareness, food apprehension, and food safety management system evaluation. First, food hazards awareness and apprehension was slightly higher than the average level, also there was a significant difference in food hazard apprehension according to food hazard awareness. However, the level of food safety information was not high, meaning consumers were not as well informed as expected. We divided food safety management system evaluation into awareness and practice, subsequently, the results of both were at a low level. Food safety information awareness’ moderating effect was also confirmed. Consumer organizations and the government need to provide specific and correct information to Korean consumers, that also implement a wide range of consumer education related policies.

Purpose: The local police system is vital for meeting community needs and maintaining order. Despite its introduction under Moon's administration, it faces criticism and conflict, especially in Jeju. This study aims to assess perceptions among Jeju residents, police, and experts, focusing on the system's effectiveness and areas for improvement, emphasizing the need for thorough evaluation and stakeholder input before full implementation. Method: This study analyzes differences in linkage tasks, collective efficiency, and security satisfaction based on age in the Jeju local police system. Using a survey of 500 Jeju residents conducted via Macroembrain, the study employs SPSS and Amos for factor analysis, reliability testing, and regression analysis. The research aims to evaluate residents' perceptions and the impact of the local police system, examining factors such as demographic variables and system awareness. Results: Hierarchical regression analysis of the Jeju local police system reveals that demographic variables(gender, age, residence, education) have minimal impact on governance linkage, collective efficiency, and security satisfaction. In contrast, awareness of the local police system significantly influences governance linkage(β=.189), collective efficiency (β=.375), and security satisfaction (β=.220), highlighting its greater importance over demographic factors. Conclusion: Research on the implementation of local police systems has been mainly theoretical. This study, using factor and regression analyses, finds that awareness of the local police system positively impacts governance, efficiency, and security satisfaction. Effective practices and improvements, including increased public awareness and training, are suggested to enhance the system’s impact.
