In IT service quality research, the relationship between the service quality and clients' satisfaction was the focus of many studies while in relationship quality research, the influence of trust and conflict on relationship commitment seems to be the focus. In this study, these two research streams are integrated and a theoretical research model is proposed consisting of IT service quality, satisfaction, trust and relationship commitment with conflict as a moderator for the overall psychological mechanism. As satisfaction represents emotional response while trust cognitive response, this research model integrated both emotional and cognitive aspects of relationship maintenance in the IT service context. Analysis of data collected from 262 employees of global IT service firm revealed the differential effects of reliability, responsiveness, assurance and empathy on satisfaction and trust. Also, depending upon the level of conflict, the effects of reliability and assurance were found to be moderated. Further analysis revealed more profound mechanism at work relating emotional and cognitive aspects in the psychology of relationship maintenance in IT service context. Practical implications are further discussed in the conclusion.

This study investigated the effect of service provider's recovery effort and pre-failure customer-employee rapport on post-recovery consumer response such as satisfaction, purchase intention, and positive Word-of-Mouth communication. First, this study explored the interaction effect of recovery effort and customer-employee rapport on post-recovery consumer response. The result shows when the level of pre-failure customer-employee rapport is high, customer's positive responses decreased slightly even though they perceived low recovery effort. However, when the level of pre-failure customer-employee rapport is low, customer's responses were decreased considerably in case of low recovery effort. Second, this study examined 'service recovery paradox' which is post-recovery consumer's satisfaction is greater than the case of no service failure. The result shows recovery paradox was not supported in all samples regardless of the level of recovery effort and customer-employee rapport. Synthetically, customer-employee rapport took a buffering role in customer response after service failure although it's not the same as error-free state.

Purpose: The purpose of this study was to investigate experiences of violence with patients or family members by paramedics working at emergency rooms. Methods: A questionnaire was administered from June 1 to 31, 2017 to 225 paramedics working at 27 emergency medical centers. The collected data were analyzed with SPSS statistics ver 24.0 program. Results: Within the past year, 208(92.9%) of 224 participants experienced violence among whom 202(90.2%) experienced verbal abuse, 193(86.2%) experienced physical threat, 89(39.7%) experienced physical violence, and 52(23.2%) experienced sexual violence. The level of violence response depending on the overlapping experience of violence type showed significant difference from emotional response (p= .001), social response (p= .001), physical response (p= .004), and overall violence response (p= .001). Conclusion: In conclusion, paramedics are frequently exposed to violence in the emergency rooms, of which they mostly experience verbal abuse. In addition, because the reporting system in the event of violence and the coping process are not well-informed, paramedics are unable to sufficiently utilize the reporting system and programs established within the institution. Therefore, the support of the legal system is needed to create a safe working environment for the medical staff who work in the emergency medical centers.

This paper proposes a method to determine the optimal utilizations of the UNIX systems. This method is developed using the definition-the optimal utilization is the maximum allowable utilization In other words, the optimal utilization is the maximum utilization that can be allowed by users while providing tolerable response time. As the tolerable response time increases, the optimal utilization increases. Therefore, the optimal utilization is obtained at the maximal value of tolerable response time. Our analysis shows tolerable response time is achieved when the average of the trivial response time is less than 0.24 seconds for a given service objective. It also shows the optimal utilization consists of three components-%wio, %sys, and %usr. By way of example, the optimal utilizations of a machine running under the UNIX operating system are computed using proposed method.

Purpose: This study aimed to identify and present suitable recognition types of policy alternative for before and after response, according to the recognition types of problems in response to violence. Methods: This study investigated 36 EMT's of 17 cities and provinces nationwide. The study was approved by the Kongju National University Institute Review Board (KNU_IRB_2021-17). Data were collected from May 1, 2021 to August 30, 2021 and analyzed by Q factor analysis using the PC-QUNAL program. Results: Recognition types of the problem in 119 EMT's response to violence were described as "I type; lack of professional manpower," "II type; inadequate policy on violence," and "III type; lack of awareness on the emergency field." Recognition types of policy alternative on response to violence by 119 EMT's were described as "Itype; training and public relations oriented," "II type; work environment improvement," "III type; violence handling specialization demand," and "IV type; recovery support seeker." Conclusion: This study provides the foundation required to develop and implement the policies regarding the response to violence; therefore, contributing to EMT's provision.

The purpose of this research is to find out how festival servicescape and human service impact the participant's emotional response and behavioral intention in terms of participants as consumers. The servicescape of festival indicated 4 common factors, named cleanliness, convenience, suitability and attravtiveness. As a result of analysis, it indicated that cleanliness and convenience from among the servicescape of festival variables are positively on positive emotion, negatively on negative emotion. And it was analyzed that all the variables of human service influence significantly on emotional response. Especially, it showed that expertise of human service variables influence on positive emotion the most, influence significantly on negative emotion. The result of relationship on behavioral intention indicated that the convenience factor of festival servicescape and expertise factor of human service influence significantly. Therefore, to operate successful festival, festival organizer should plan and manage the festival based on factors which comprises festival servicescape and human service.

As the number of public Web Services increases, there will be many services with the same functionality. These services. however, will vary in their QoS properties, such as price, response time and availability, and it is very important to choose a best service while satisfying given QoS constraints. This paper brings parallel branching and response time constraint of business processes into focus and investigates several service selection plans based on multidimensional multiple choice Knapsack model. Specifically. proposed in the paper are a plan with response time constraints for each execution flow, a plan with a single constraint over the whole service types and a plan with a constraint on a particular execution path of a composite Web Services. Experiments are conducted to observe the performance of each plan with varying the number of services, the number of branches and the values of response time constraint. Experimental results show that reducing the number of candidate services using Pareto Dominance is very effective and the plan with a constraint over the whole service types is efficient in time and solution quality for small to medium size problems.

This study was designed by paying attention to the negative aspects of the performing arts service. As interest in performing arts increases, various studies on services are being conducted in the performing arts field as well. However, although research on the positive side of performing arts services is steadily increasing, research on the negative side is insufficient. In this study, the limitations of existing studies were supplemented and the study was conducted by applying the Stimulus-Organism-Response (S-O-R) model for empirical research. The effect of failure of performing arts service as a stimulus variable on the response to complaint behavior through negative emotion as an organism was verified. As a result of the analysis, it was found that among the factors of failure in performing arts services, performance works and personal services had a significant influence on negative emotions. In addition, the influence of negative emotions on public and private complaints was confirmed. Lastly, this study will have academic significance in that it analyzed consumers by converting the factors of service failure of performing arts into variables.

Security incidents using vulnerabilities in cloud services occur, but it is difficult to collect and analyze traces of incidents in cloud environments with complex and diverse service models. As a result, the importance of cloud forensics research has emerged, and infringement response scenarios must be designed from the perspective of cloud service users (CSUs) and cloud service providers (CSPs) based on representative security threat cases in the public cloud service model. This simulated hacking-based proactive cloud infringement response framework can be used to respond to the cloud service critical resource attack process from the viewpoint of vulnerability detection before cyberattacks occur on the cloud, and can also be expected for data acquisition. Therefore, in this paper, we propose a framework for preventive cloud infringement based on simulated hacking by analyzing and utilizing Cloudfox, a cloud penetration test tool.
