With the growing demand for online food delivery (OFD) services via Online to Offline (O2O) platforms, it is required for academic researchers to identify the success factors of OFD businesses. In line with this, this research examines the impact of the core service attributes of a restaurant (hygiene, interactivity, trust,and popularity) on business success in the OFD platform context from the perspective of information asymmetry. Furthermore, the moderating effects of hygiene factor between the core service attributes and the success of restaurants are evaluated. We utilize 1,146 restaurants registered on the largest OFD platform in Korea. The results of this study demonstrate that hygiene (certification), trust (franchise), popularity (favorite) factors have positive impacts on the success of OFD businesses. Moreover, we find that franchise restaurants with high response rates to customer reviews and inquiries achieve higher sales when they have hygiene certifications than those without the certification do. The key findings bear significant contributions to prior literature by empirically substantiating the pivotal role of service quality signals in fostering restaurant success on the OFD platforms. In addition, this study provides business implications for restaurants in O2O platform.

In most of the existing real-time schedulers producing the total value as large as possible, the service times for all schedulable tasks are computed at each time a new task arrives. If all scheduled tasks would be executed completely before a new task arrives, the schedule may produce the greatest total value. But this is not always true in real situations. In many cases, (a) new tasks arrive(s) before all the scheduled tasks are executed completely. In this paper, we propose a unique scheduling algorithm for real-time tasks. The proposed algorithm determines the service times only for some tasks with earlier deadlines while the existing algorithms determine the service times for all tasks. This partial computation decreases the average scheduling complexity ramatically, even though, in the worst case, the complexity of the proposed algorithm becomes O(N2), which is equal to that of a previous algorithm that has been known as a less complicated one.

In modern society, the online to offline (O2O) market has become an emerging market. Based on social and cultural phenomena, the importance of "FOODTECH" linked with mobile applications is growing in the food and restaurant industry. This study examined subjective food application service quality, perceived value, and post-purchase behavior intentions. According to this study, of foodtech service quality attributes, only information, mobility, and reliability had positive (+) relationships with perceived value. However, foodtech service quality attributes did not have a direct impact on behavior intentions. Perceived values had a positive (+) relationship with behavior intentions and showed full mediation effects between foodtech service quality attributes and behavior intentions. Based on these results, future research on the relationship among food application service quality, perceived value, and post-purchase behavior intentions is needed.

On-Demand services have emerged as one of the core business strategies for delivering new experiential values by providing customized services in different user-needs nowadays. Based on the Stimulus-Organism-Response (S-O-R) framework, this paper focuses on the factors of environmental stimulation and emotional states of the demand-side that induce continuous intention of use from the On-Demand services. The study defines 'Informativeness', 'Fulfillment', 'Trust', and 'Convenience' as the properties of the On-Demand services and considers 'Playfulness', 'Customer Return on Investment (CROI)', and 'Service Excellence' as the aspects of the experiential values. The research shows that 'Fulfillment', 'Trust' and 'Convenience' affected the experiential value in 'Kakao Taxi (On-Demand transportation service)' while 'Informativeness', 'Fulfillment', 'Trust of platform', and 'Convenience' are represented as the related factors to the experiential value in 'Baedal Minjok (On-Demand food delivery service)'. The experiential value factors, 'CROI' and 'Service Excellence', are shown directly related to the continuous intention of use in both services. A partial mediation relationship is, furthermore, observed between the aspects of 'CROI' and 'Service Excellence' in Kakao Taxi and its 'Convenience' and 'Continuous intention of use.' In Baedal Minjok, a partial mediation relationship is found between the 'CROI' with its aspects of 'Trust of the platform', 'Convenience', and 'Continuous intention of use' as well. The results of this study may contribute a comprehensive understanding of the purpose of On-Demand services and its needs from the demand-side thus can be helpful for the supply-side.

Recently, many Korean firms have suffered financial losses and damaged firm's trust due to information security incidents. Hence, a lot of firms have realized the importance of the information security. In particular, the demand for information security certification has increased. This study examined the effect of information security certification using the event study methodology. Our research shows that the announcement of the information security certification significantly influences the market value of the corresponding firm. The certified firms rise, on average, o.4993% (-2 day), 0.5462% (+1 day) of their market value. Further, we found that the financial sector in our data showed a 1.4% higher abnormal returns than the nonfinancial sector. On the other hand, whether a firm first acquired the information security certification is not significant. Our paper presents that it is possible to analyze the effect of the information security certification using the event study. We are expected to be used in making a decision for the investment of information security. Also, our results indicate that the firm which have acquired the information security certification should actively announce that fact.

This study classified five types of online food subscription economy: replenishment, curation, surprise, membership, and visitation. An online survey was conducted with 314 customers who experienced 5 types of online subscription economy. This study selected the characteristics of the food subscription economy as convenience, perceived personalization, economic utility, and timeliness through previous studies. The effect of the four characteristics on perceived value (utilitarian and emotional) and the relationship between customer engagement and perceived value, which are dependent variables that have never been used in the food subscription economy, were verified through the S-O-R model. In this relationship, we demonstrated how consumers' personal tendencies, such as need for cognitive closure and self-efficacy, mediate between timeliness and perceived value related to online food delivery. The study results are as follows. Perceived personalization, convenience, and timeliness had a positive effect on the utilitarian value in the order. It also had a positive effect on emotional values in the order of perceived personalization and timeliness. On the other hand, economic utility had no significant effect on practical branches. Customer engagement had a positive effect in the order of emotional value and utilitarian value. The lower the need for cognitive closure the more positive the utilitarian value. The lower the self-efficacy, the more positive the emotional value was perceived. Through the above study, companies that want to operate or start an online food subscription economy need a strategic approach rather than unreasonable price discounts in pricing policy. In addition, it is necessary to focus on marketing activities that provide emotional value by focusing on perceived personalization, which is the satisfaction factor of online food subscription.

This research aims to find out the existence of considerable induced effect that the conventional I-O model cannot. First, we construct an environmental Social Accounting Matrix for Korea by combining statistics on the Korean GDP and I-O with physical data on the fossil energy consumption and $CO_2$ emissions. The impacts of productive activities on fossil energy consumption and $CO_2$ emissions are evaluated by calculating the e-SAM multipliers. By applying decomposition technique further, we get direct, indirect, and induced effects of production activities by industry. The result of decomposing the e-SAM shows that while the direct effect of the electricity industry is large, its indirect effect is very small. In the case of the primary metal industry, both the direct and the indirect influence of this industry were very large. On the contrary, in case of the service industry, the induced effect of fossil energy consumption was as high as 50% of the gross effect. These results suggest that different energy policies should be established for different industries. Also, the findings show the e-SAM model is better than I-O model in analyzing implications of policies on energy use in the economy.
