O2O(Online-to-Offline) commerce, a kind of multi-channel, is used in various industries such as accommodation, food and beverage, transportation, and real estate. The O2O commerce, a channel of integrating online and offline, overcomes the limitations of traditional online commerce, where a customer made a purchase decision without direct experience. Despite this advantage of O2O, if the online-offline channel is not effectively linked, customer's complaints would occur due to service failure. This study, with regard to O2O service failure circumstances, intends to investigate the effect of customer's perceived justice on their emotional response, recovery satisfaction, followed by intention to repurchase. Perceived justice in this study is composed of distributive justice, interactional justice, and procedural justice. Furthermore, this study explores the moderation effect of O2O industry types in the relationship between perceived justice and emotion. An O2O industry type is classified into accommodation, food and beverage, and transportation. A hypothesized research model was empirically tested using a structural equation model. The current study collected 433 questionnaires and the target respondents are customers who have experienced service failure in O2O commerce. The empirical results showed that O2O commerce more effectively conducts service recovery strategy and causes positive customer response by integrating online and offline channel. One of the ultimate purposes of O2O service providers is to reduce the likelihood of service failures and to recover more quickly and efficiently by linking two channels rather than using a single channel. This study suggested that the O2O channel is effective in influencing customer satisfaction and loyalty by inducing customer's positive emotions in recovering service failure.

The emergency recovery scheme in time of a disaster or accident up to now has been focused on how to build a backup for the public service or communication network in national scale, also, all the mobile operators have done as recovery scheme for the equipment failure in their network was to make a backup copy of billing data or package data, and they have usually studied only on the backup and failure recovery scheme in the circuit-switched network. However, since it has become more probable recently that a disaster or accident could occur in the switching office buildings, a recovery scheme in time of the failure of these entire switching offices became necessary. The purpose of this paper is to propose various recovery schemes, and by having checkups on many issues that could arise while carrying out these schemes, it presents the best solution for each issue. Moreover, it presents the future tasks that need to be studied as well as initial study directions.

This study aims to investigate the relationship between service recovery justice, residual emotions, and customer behavior. It empirically verifies that low justice in service recovery affects residual emotions and, in turn, has an impact on customers' negative behaviors. Furthermore, this research distinguishes customer-brand relationship quality into emotional relationship quality and cognitive relationship quality and seeks to validate that the type of relationship quality may influence the extent to which the justice of recovery processes affects residual emotions. Data was collected through surveys, and hypotheses were tested using structural equation modeling. The research findings indicate that among the dimensions of service recovery justice, procedural justice and interactional justice significantly influence residual emotions. Moreover, residual emotions have a significant impact on both the intention to revisit and the intention to engage in negative word-of-mouth. In addition, the impact of distributive justice and procedural justice on residual emotions was found to be higher for cognitive relationship quality than emotional relationship quality, and the impact of interactional justice on residual emotions was found to be higher for emotional relationship quality than cognitive relationship quality.

We analyze the performance of MAC-layer Reed-Solomon error recovery in the cdma2000 1xEV-DO Broadcast and Multicast Services (BCMCSs) environment, with respect to the size of the ECB (Error Control Block) and the air-channel condition, and establish the relationship between ECB size, error recovery capacity and service latency. From this we propose an adaptive error recovery scheme which adjusts the size of the ECB to reflect the environment of the mobile nodes so as to meet the required service quality (target bit error-rate), while reducing the latency of real-time applications. Extensive simulation results show the effectiveness of our approach compared to the current static scheme. Proposed adaptive schemes achieves near optimal solution with respect to service latency while satisfying the required service quality.

Malachite green (MG), a triphenylmethane dye, is carcinogenic, mutagenic, teratogenic, a respiratory toxin, and causes chromosomal fractures. It is not permitted for use as an aquaculture veterinary drug in a number of countries. Sensitive extraction methods for MG and leucomalachite green (LMG), which have long residence times in fish tissues, were developed. For LMG, the average recovery of liquid extraction (LE) ranged from 41.71 (yellowtail) to 71.60% (snakehead); the recovery of liquid-liquid extraction (LLE) was between 67.68 (yellowtail) and 83.68% (snakehead); and the average recovery of solid-phase extraction (SPE) ranged from 84.16 (yellowtail) to 92.92% (shrimp). The recovery of MG was less than 30% with SPE. However, the dye is found primarily as the colorless reduced leuco form in fish tissues.

The disaster recovery refers to policies and procedures to ensure continuity of services and minimize loss of resources and finances in case of emergency situations such as natural disasters. In particular, the disaster recovery method by the cloud service provider has advantages such as management flexibility, high availability, and cost effectiveness. However, this method has a dependency on a service provider and has a structural limitation in which a user cannot be involved in personal data. In this paper, we propose a protocol using proxy re-encryption for data confidentiality by removing dependency on service providers by backing up user data using blockchain and distributed storage. The proposed method is implemented in Ethereum and IPFS environments, and presents the performance and cost required for backup and recovery operations.

Purpose - Past research has not given much attention to the roles of consumers' social relationship type in the effects of justice type of service failure recovery alternatives on their satisfaction to the alternative exposed to them. Current research aimed at exploring the moderation role of consumers' social relationship central versus peripheral in the effects of justice types of service failure recovery alternatives on the recovery satisfaction, and this research also explored whether the level of satisfaction to interaction justice-focused alternative are significantly different between the two, their social relationship central and peripheral relationship. Research design, data, and methodology - 2(social relationship central versus peripheral) between-subjects design was employed. 50 participants for each experimental group there were. Participants of each group took forceful steps in choosing one between the procedural justice-focused alternative and the distribution justice-focused alternative. χ²-analysis was used to verify that the number of choosing each alternative becomes different between the two experimental groups, and a one way ANOVA was used to verify that the extent to which participants are satisfied to the alternative chosen by them becomes different between the two groups. Results - The number of participants choosing procedural justice-focused alternative at the group of social relationship central was larger than that at the group of social relationship peripheral, whereas the number of participants choosing distribution justice-focused alternative at the group of social relationship peripheral was larger than that at the group of social relationship central. And the level of satisfaction to procedural justice-focused alternative at the group of social relationship central was higher than that at the group of social relationship peripheral, whereas the level of satisfaction to distribution justice-focused alternative at the group of social relationship peripheral was higher than that at the group of social relationship central. In addition, the level of satisfaction to interaction justice-focused alternative was not significantly different between the two groups. Conclusions - Marketers should give attention to the type of justice when developing alternatives by which consumers' service failure can be recovered. They should suggest procedural justice-focused alternative to consumers under social relationship central, whereas they should develop distribution justice-focused alternative for consumers under social relationship peripheral. And in the process of recovering service failure they also should focus on interaction justice.

This study is directed to examine the most useful restoration strategies for turning the customers' dissatisfaction caused by unsuccessful spa service to the satisfaction through each fair factors and tries to suggest the practical schemes to cope with complaints and dissatisfaction of spa service customers by establishing the system dealing with customers' complaints. And this verifies the relationship between the alternative attraction and the intention of conversion as the action after the restoration from the unsuccessful services. Moreover, it analyzes the mediation effect that a formation of reliance through the restoration of unsuccessful services has. To achieve the purpose of this study, the subject got decided as women who are customers of private spa facilities situated in Seoul and Gyeonggi-do region for the purpose of skin care in 1 year recently. After understanding their experiences of complaining about the services, this study investigates the alternative attraction and the intention of conversion as the next action and the perception of fairness and trust in the efforts of Spa service business for recovery. As the result of verifying hypothesis, it is shown that the recovery satisfaction increases when the 3 points of the distributive justice, procedural justice, and interactional justice, which are the fairness factors of the effort to restore services according to the quality of service, are more positive. In the relation among recovery satisfaction, trust, the alternative attraction, and the intention of conversion, the result was that recovery satisfaction affects trust in positive way and alternative attraction in negative way. However, the positive and meaningful result came out in contrast with the hypothesis which predicted the negative effect of recovery satisfaction on the intention of conversion. Furthermore, it means that indirect effectiveness which carries trust and alternative attraction should be considered instead of the direct effectiveness that the recovery satisfaction affects on the intention of conversion. In this study, it can be interpreted that the combined increase of the trust and the alternative attraction makes the intention of conversion higher rather than the higher intention of conversion following the decrease of the recovery satisfaction in view of the result that the indirect effectiveness is high between the recovery effort and the intention of conversion. In the relation among the intention of conversion, trust, and alternative attraction, the intention of conversion got influenced in positive way and negative way by trust and alternative attraction respectively and trust influenced the alternative attraction negatively as well. It means the high quality of services or the recovery of services has a direct causation which carries conviction to the customers' intention of action.

As Electronic Commerce is getting larger, the volume of Internet-based commerce by enterprise is also getting larger. This phenomenon applies to Internet EDI, Global Internet Business, and CALS information services. In this paper, a new type of cryptographic key recovery mechanism satisfying requirements of business environment is proposed. It is also applied to enterprise information infrastructure for managing employees' task related to handling official properties of electronic enterprise documents exchange. This technology needs to be complied to information management policy of a certain enterprise environment because behavior of cryptographic key recovery can cause interruption of the employees' privacy. However, the cryptographic key recovery mechanism is able to applied to any kind of information service, the application areas of key recovery technology must be seriously considered as not disturbing user's privacy It will depend on the policy of enterprise information management of a specific company.
