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.

In this paper, we identified the factors influencing on the continuous use intention of social commerce and analyzed the proposed model empirically using structural equation model, which was developed by considering hedonic and utilitarian shopping value, trust, satisfaction, familiarity, social influence, and perceived price. We collected data for this study by surveying the consumers who had an experience of purchasing through social commerce. An analysis of 212 respondents indicated that utilitarian and hedonic shopping value influenced on satisfaction as both of shopping value are significant statistically. Social commerce gives more attraction their consumers by reducing the price to half, whereas they are expected to present playfulness of shopping. Familiarity, social influence, and perceived price are influential factors in a purchase of social commerce sites. We discuss the implications of our findings for both theory and practice.

The study is focused on analyzing the SNS using characteristics of the people surveyed, as for the SNS acceptance channel of the food service corporations, accounted voluntarily for 71%. The SNS food service information regarding information of menu, location of store, price, coupon, taste evaluation, event, promotion, reservation and store atmosphere was researched. The most preferred information sharing for SNS food service were researched and found Facebook, blog and others in increasing order. The most preferred media to obtain SNS food service information were smart phone, desktop computer and others. The result of verifying differences in the perceived ease of use were also evaluated according to the food service corporation of SNS using characteristics of the people and was found: the longer period of SNS use, longer was access time: more number of visiting times, higher perceived ease of use. As for the difference in the perceived service value: longer the period of SNS use, more preferred was the blog: the more number of visiting times, the higher perceived service value. As for the difference in the online mouth-to-mouth intention: longer the period of SNS use, longer was access time: the more number of visiting times, the higher online mouth-to-mouth intention. Therefore, these research results provide useful implications in the working-level aspects such as providing basic data and the academic approach of the study, when the food service corporations establish marketing strategies through SNS.

Utilization of information and communication technologies is commonly accepted as important to value creation in the knowledge economy. Nevertheless, empirical findings from our business case studies often show that while sophisticated technological tools may be developed, the potentials are not realized. It is evident that technology is subject to adaptive and emergent strategies of use, diverging from the original intention. Within this space of opportunities, we elaborate the importance of constructing strategic concepts as communication tools to support organisational implementation of technologies. We use the concept of organisational implementation as a way of taking the technology into use in order to support changes and value creation in the user organisation. In this paper we present our findings related to how use and experiences are conditioned by the users' expectations. We have conducted a business case study in order to understand and explore how users employ and use a particular wireless technology infrastructure. On behalf of the infrastructure vendor, we have studied three different organisations that use this technology. The overall research goal of our joint research project was to find out what is good use and for whom. We find that users struggle to go beyond the expectations they had when they were conceptualising and telling us about their practice. We have good indications that a narrowed consciousness was also conditioning the users' use of the technology. In this paper we draw the conclusion that technological implementations towards changing work practices and value creation must not be viewed by the company solely as a knowledge acquisition process, but as a process of knowledge creation. Organisational implementation is an ongoing process, a learning process at both the organisational and individual level. Flexible tools and technologies are constituted and shaped in interaction and communication in the workplace. Based on that knowledge, we build up an argument for an organisational implementation framework, including strategic discussions, learning spaces, and concept constructions.

The objective of this study was to prove the effect of pig slurry application with charcoal on nitrogen use efficiency (NUE), feed value and ammonia (NH₃) emission from maize forage. The four treatments were applied: 1) non-pig slurry (only water as a control), 2) only pig slurry application (PS), 3) pig slurry application with large particle charcoal (LC), 4) pig slurry application with small particle charcoal (SC). The pig slurry was applied at a rate of 150 kg N ha^-1, and the charcoal was applied at a rate of 300 kg ha-1 regardless of the size. To determine the feed value of maize, crude protein, dry matter intake, digestible dry matter, total digestible nutrient, and relative feed value were investigated. All feed value was increased by charcoal treatment compared to water and PS treatment. Also, the NUE for plant N was significantly higher in charcoal treatments (LC and SC) compared to PS treatment. On the other hand, there is no significant difference for feed value and NUE between LC and SC. The NH₃ emission was significantly reduced 15.2% and 27.9% by LC and SC, respectively, compared to PS. Especially, SC significantly decreased NH₃ emission by 15% compared to LC. The present study clearly showed that charcoal application exhibited positive potential in nitrogen use efficiency, feed value and reducing N losses through NH₃ emission.

In this paper we use uniform cubic spline polynomials to derive some new consistency relations. These relations are then used to develop a numerical method for computing smooth approxi-mations to the solution and its first second as well as third derivatives for a second order boundary value problem. The proesent method out-performs other collocations finite-difference and splines methods of the same order. numerical illustratiosn are provided to demonstrate the practical use of our method.

In this paper, we devise a Shapley-value-based covert channel in smartphones. More specifically, unlike ordinary use of Shapley value in cooperative game, we make use of a series of Shapley values, which are computed from sensor data collected from smartphones, in order to create a covert channel between encoding smartphone and decoding smartphone. To the best of our knowledge, we are the first to contrive covert channel based on Shapley values. We evaluate the encoding process of our proposed covert channel through simulation and present our evaluation results.
