The Internet of Things (IoT) is an Infrastructure which allows to connect with each device in physical world through the Internet. Thus IoT enables to provide meahup services or intelligent services to human user using collected data from those devices. Due to these advantages, IoT is used in divers service domains such as traffic, distribution, healthcare, and smart city. However, current IoT provides restricted services because it only supports monitor and control devices according to collected data from the devices. To resolve this problem, we propose a design and implementation of personalized IoT service base on service orchestration. The proposed service allows to discover specific services and then to combine the services according to a user location. To this end, we develop a service ontology to interpret user information according to meanings and smartphone web app to use the IoT service by human user. We also develop a service platform to work with external IoT platform. Finally, to show feasibility, we evaluate the proposed system via study.

The lifestyle of customers visiting nail shops is categorized into four such as the types of 'pursuit of fashion', 'pursuit of brand', 'conservative frugality', 'premeditated pursuit'. Subjects are divided into 3 groups such as a 'pragmatist group', an 'achievement-oriented group' and a 'brand-oriented group'. Customers satisfaction level was measured in the subcategories of a 'personal service', a 'technical service', a 'facility service' and an 'after-sales service'. Their satisfaction levels depending on the types of customers' lifestyle have meaningful differences in a 'technical' and an 'after-sales' service. The 'pragmatist group' shows the highest mark in a 'personal service' and an 'achievement-oriented', it prefers the 'personal' and 'facility service' evenly. The 'brand-oriented' group shows high concern in the 'technical service'. Concludingly, the types of customers' lifestyle which influence their revisiting of the nail shop have deep relation to customers' satisfaction level in the 'personal', 'technical', 'facility', and 'after-sales service' of nail shops. Especially the 'facility service' is highly influential in customer's revisiting.

Driving simulators are useful tools not only to test the components of future cars but also to evaluate the telematics service and HMI (Human-Machine Interface). However driving simulators cannot be implemented to test and evaluate the telematics service system because the GPS (Global Positioning System) which contains basic functional support for the telematics module do not work in the VR (virtual reality) environment. This paper presents a method to implement telematics service to a driving simulator by developing the GPS simulator which is able to emulate GPS satellite signals consist of NMEA-0183 protocol and RS232C communication standards. It is expected that the driving simulator with the GPS simulator can be used to study HMI and human-factor evaluations of the commercial telematics system to realize the HiLES (Human-in-the-Loop Evaluation System).

Online financial counseling services are increasingly expanding with the rise of artificial intelligence-based chatbots. It is very important to examine the effects of emoticons noted as alternatives for communicating emotions in online communication between consumers and companies. In this paper, we examine how the use of emoticons affects the consumer's response and investigate the moderating roles of type of counseling agents (human vs. chatbot) and the consumer's subjective financial knowledge. The results show that the use of emoticon in the conversation brings a positive effect on the consumer's intention to use of online chat counseling service. When participants had relatively low subjective financial knowledge, they had higher intention to use online chat counseling services with emoticons only when the agent type was chatbot. When the type of counseling agent was human, this positive effect of the emoticon did not occur. On the other hand, when participants had relatively high subjective financial knowledge, they had higher intention to use online chat counseling service with emoticons only when the agent type was human. This study contributes to providing practical implications to build online chat counseling service using chatbot in the financial industry by studying users' intention depending on the type of agents and the level of their subjective knowledge.

This study investigated the effects of the chatbot's level of anthropomorphism - closeness to the human form - and its self-disclosure - delivery of emotional exchange with the chatbot through its facial expressions and chatting message on the user's intention to accept the service. A 2 (anthropomorphism: High vs. Low) × 2 (self-disclosure through facial expressions: High vs. Low) × 2 (self-disclosure through conversation: High vs. Low) between-subject factorial design was employed for this study. An online survey was conducted and a total of 234 questionnaires were used in the analysis. The results showed that consumers used chatbot service more when emotions were disclosed through facial expressions, than when it disclosed fewer facial expressions. There was statistically significant interaction effect, indicating the relationship between chatbot's self-disclosure through facial expression and the consumers' intention to use chatbot service differs depending on the extent of anthropomorphism. In the case of "robot chatbots" with low anthropomorphism levels, there was no difference in intention to use chatbot service depending on the level of self-disclosure through facial expression. When the "human-like chatbot" with high anthropomorphism levels discloses itself more through facial expressions, consumer's intention to use the chatbot service increased much more than when the human-like chatbot disclosed fewer facial expressions. The findings suggest that chatbots' self-disclosure plays an important role in the formation of consumer perception.

Service innovation is one means of gaining an advantage in a highly competitive environment. Although numerous studies have stressed the importance of service innovation, traditional good-dominant logic is still used in service innovation literature. Furthermore, few studies have been conducted on the link between service innovation and its antecedents in terms of service-oriented approach. To fill the gap, this article theoretically and empirically examines service innovation and its antecedents and consequences. Based on service-dominant logic and resource advantage theory, the current study aims to understand the effect of antecedents on service innovation as well as to identify the effect of service innovation on firm performance (i.e., non-financial and financial performance). Three service innovation activities, namely service creation-focused innovation, service delivery-focused innovation, and customer interaction-focused innovation, and four antecedents of service innovation, including human resource management capability, collaboration capability, marketing capability, and information technology capability, are identified based on Den Hertog (2000)'s service innovation framework. By using the empirical data collected from 189 service firms in Korea, this study explores the causal relationship among antecedents, service innovation and firm performance. Findings indicate that human resource management and marketing capabilities influence the three types of service innovation, whereas collaboration and information technology capabilities have a significant effect on both service creation-focused innovation and service delivery-focused innovation. In particular, human resource management capability is strongly related to customer interaction-focused innovation. The three types of service innovation have a positive influence on non-financial performance, whereas service delivery-focused innovation and customer interaction-focused innovation positively influence financial performance. These results support the crucial effects of antecedents, such as human resource management, collaboration, marketing and information technology capabilities, on service innovation.

Interest about the effect of military service is increasing because of the renewal of military service incentive system in Korea. In the background, men has been experienced which suffer monetary and non-monetary damages through the compulsory military service in Korea. However there are few studies that analyze the labor market effect of military service. This study takes advantage of male worker's data of 10th KLIPS(Korea Labor & Income Panel Survey) in 2007 and analyze the wage effect of military service. According to empirical result using Mincerian earnings function, the positive effect of military service appeared. These result shows men who finished military duty have an monetary advantage in Korean labor market unlike general perceptions on military service.

Purpose / Approach : This study aims to analyze the level of public service motivation and its antecedents by using survey data of 1,498 professional employees in public and private hospitals. Findings : Among job-related, organization-related, and socialization-related factors of professional employees, the socialization factors have a strong effect on individual's overall and the four sub-dimensions of public service motivation. While the effect of organizational identification is prominent in the public hospital, professional identification is more powerful in the private hospital. Person-job fit and person-organizational value fit also play a significant role in determining public service motivation. Organizational vision salience in public hospital has negative effect on public service motivation and attraction-to-public-service dimension. The significant determinants and its effect size are different according to hospital type and each sub-dimension of public service motivation. Practical Implications : The empirical findings show that individual's level of public service motivation in hospitals could be enhanced through the interaction between individual and their organization, and various organization-related factors. Further implications of the study are discussed from human resource management perspective in hospitals.
