To propose a contents model for children's smart watch, this study interview 15mothers who have a child using smart watches. Most mothers purchase smart watches for children to warrant their security and manage their schedules, and they use them for sending a call or text to their children, tracking or managing children's location and schedule. Mothers were satisfied with a smart watch's function of communication and safety management, but dissatisfied learning-oriented contents and worrried about bad influenced on children development. Through in-depth interviews, this study propose a persona model for children's smart watch for enhancing parent-child interaction and physical cognitive language socioemotional convergence play contents.

Recently, business environment is spreading from singular business to supply-chain problem. SCM(Supply Chain Management) is changing from closed and static to opened and dynamic environment, so these environment changes of SCM require to enterprise different approach than past. As supply chain is becoming opened and dynamic, a claim is being naming that converse of real-time the get reaction from to recognizing the level of supply chain problem, grope of alternative plan to solving this problem and choosing optimum alternative plan raise the enterprise competitive. But until present, the research to deal with these changes of SCM is on insufficient situation. Thus in this paper proposes the agent system by a way of realizing dynamic supply chain. The agent is going to accomplish the management activities in real-time depends on environment and given condition and designed for solving problems development and maintenance. Also, algorithms performance of the agent is tested on TAC SCM environment. Agents in TAC SCM are simulations of small manufacturers, who must compete with each other for both supplies and customers, and manage inventories and production facilities.

Among the elderly and patients with mild brain diseases (such as dementia and stroke), when there is a certain degree of self-acting ability and cognitive ability, exercise and cognitive rehabilitation are often required. However, since most of the existing rehabilitation systems are separated or specialized in exercise or cognitive rehabilitation, there is a need for a form linking both. In this paper, we propose a game-type rehabilitation system that enables both exercise and cognitive rehabilitation using CAN communication protocol, one of ICT technologies. This system uses the CAN BUS structure to separate and combine each individual module constituting the rehabilitation system in various forms. A prototype of the proposed system was actually produced to show that various types of rehabilitation environments can be implemented according to the degree of cognitive ability and motor ability of the patient (or the elderly). In addition, through several experiments using this system, it is possible to implement exercise/cognitive parallel rehabilitation applicable to various environments.

The purpose of this study was to examine the characteristics of dental homepages in korea to discuss how they could be improved better. The findings of this study could be described as below : First, dental homepage should include differentiated, specialized content and features. Second, the use of three-dimensional image or multimedia would contribute to increasing people's understanding of dental treatment or general dental information and elevating the effectiveness of dental publicity activities. Third, the want ad and order system used by the business sector or hospital would serve to multiply the management efficiency of dental institutions. Fourth, dental hospitals and clinics that belong to the same network or franchise need to make publicity banner for feasible mutual link, and the use of the same homepage design or common logo would be effective for better image and publicity activities. Fifth, it would be convenient to add the map search function or inquiry system. Seventh, if multiple types of services, such as entertainment or game, are prepared, it would be possible for dental institutions to project a better image and to induce visitors to hit the sites again.

Designing cost-effective service recovery strategies mix has been recognized one of important issues by both service researchers and practitioners. In spite of the rising interest in them, there has been scarce studies on them. In this paper, we try to find cost-effective service recovery strategies mix via game-theoretic modeling. Especially, we focus on the possible incentives such as voucher type reward and service re-performance which have different cost structure. We investigated three questions about the topics as follows:(1) Should the service firm use the possible incentive scheme such as voucher and service re-performance for service recovery?, (2) How much voucher and service re-performance is adequate for service recovery under diverse service failure severity level?, (3) How much voucher and service re-performance is adequate for service recovery under diverse threshold level to make the customer repurchase? The results are as follows:(1) The use of both voucher and service re-performance for service recovery results in greater surplus for the service firm. (2) The higher gets the service failure severity level, the higher total incentives are required in the equilibrium. As service failure severity level gets higher, higher level of discount might be more useful to the service firm. However, service re-performance should be cut down above some critical level of service failure severity in the equilibrium. (3) The higher gets the threshold level to make the customer repurchase, the higher incentives are required in the equilibrium, and the higher portion of voucher incentive is required relative to that of service re-performance in the equilibrium.

This study investigated the factors influencing the knowledge acquisition of Thai local partners from advanced foreign partners through international joint ventures(IJVs). For this purpose, this study initially identified three dimensions of characteristics in the context of IJVs that would influence local partners' knowledge acquisition - a local partners' own characteristic (absorptive capacity), a relationship characteristic with IJVs (proximity to the equal equity ownership), and a relationship characteristic with foreign partners (trust), and examined their effects on local partners' knowledge acquisition. The study further investigated the moderating effects of the tacitness of knowledge on the relationships between those characteristics and knowledge acquisition. Based on the data collected from Thai IJV local partners, results revealed that a local partners' own characteristic, absorptive capacity, and a relationship characteristic with IJVs, proximity to the equal equity ownership, had a strong positive effect on local partners' knowledge acquisition. Results further showed that the tacitness of knowledge strengthened the relationships between absorptive capacity and knowledge acquisition and between trust and knowledge acquisition, but not the relationship between proximity to the equal equity ownership and knowledge acquisition.

Over the last twenty years, sponsorship has been used very widely as an important marketing tool that enhances corporate image. Since it has proven to be effective in creating positive perceptions of the company, many marketers have sponsored a variety of consumer-related activities. However, sponsorship has also been criticized as it can be related to ambush marketing and excessive commercialism which trigger negative consumer responses. Unlike the existing study on the sponsorship marketing, this study intends to investigate its negative effects. The study was conducted based on the persuasion knowledge model which was proposed by Fristed and Wright (1994) and investigated consumer responses to ulterior motive of sponsorship marketing. According to the persuasion knowledge model, consumers activate their persuasion knowledge to see the agent's commercial motive; there are several antecedents to the persuasion knowledge activation such as the source familiarity, the marketer's effort and the appropriateness of persuasion. Also, existing studies have pointed out the sponsor-event fit and the sponsor's integrity as crucial factors which influence consumer attitude. By taking a survey of people who watched the 2010 Guangzhou Asian Games, we tried to examine how the sponsor familiarity and the sponsor-event fit as pre-existing variables which have been formed based on the prior consumer knowledges/memories as well as the sponsor effort and the sponsor integrity as situational variables activated based on the specific persuasion episode influenced persuasion knowledge. We also tried to test the potential moderating role of sponsorship type (i.e., official sponsorship versus marketing focused) on the causal path from the persuasion knowledge and the consumer attitude from the perspective of the appropriateness of persuasion. The results show that the sponsor familiarity, the sponsor-event fit, and the marketer's effort have significant effects on the persuasion knowledge activation, and the sponsorship type has moderating role in the sponsorship effectiveness. The theoretical and practical implications of the results are discussed.

Recently, the importance of elemental technologies constituting smart factories is increasing due to the 4th Industrial Revolution, and simulation is widely used as a tool to learn these technologies. In particular, PID control is an automatic control technique used in various fields, and most of them analyze mathematical models in certain situations or research on application development with built-in controllers. In actual educational environment requires PID simulator training as well as PID control principles. In this paper, we propose a model that enables education and practice of various PID controls through 3D simulation. The proposed model implemented virtual balls and Fan and implemented PID control by configuring a system so that the force can be lifted by the air pressure generated in the Fan. At this time, the height of the ball was expressed in a graph according to each gain value of the PID controller and then compared with the actual system, and through this, satisfactory results sufficiently applicable to the actual class were confirmed. Through the proposed model, it is expected that the rapidly increasing elemental technology of smart factories can be used in various ways in a remote classroom environment.

The voluntary agreement between industries and government on the recycling of wastes has been analysed. The agreement is one of the threatened voluntary agreements. Theoretically these agreements make it possible to fulfill recycling goals with minimized cost. It is the objective of this paper to evaluate the efficiency of the voluntary agreement on recycling wastes by examining of Nash Equilibrium. In the first place, the equilibrium of a bilateral agreement between the representative of industries (association of firms) and government will be analysed to confirm if cost minimization strategies by the association result in a sub-game perfect Nash Equilibrium. This is followed by an analysis of a multilateral agreement among the members of the association to see how the equilibrium and efficiency conditions change. We tried to find some implications that the result of the analysis casts on the environmental policy matters.

We live in the information technology era and experience the rapid global information environment change through Internet. Therefore, as distribution channels and service qualities in our daily lives are provided through Internet, these changes have been the foundation of constructing a new society. Naturally, the use of computer is widely spread out and it is hard to find any company that doesn't use computer in its work. However, the computer skills of those who are in their fifties cannot reach to what the companies need for them even though they are main working groups in our society. In addition, the Internet access rate of homemakers in their late forties and over fifties are low due to their lack of computer knowledge even though they are the target customers of the Internet service. Under these circumstances, we offer a lecture using simulation techniqe through which anybody can easily follow the instructions via the "Help" menu not a boring lecture that just show the text and reads it. Besides, each class will show you how to start Internet/ how to finish it, how to register a website, how to use e-mail, etc. So, it will let you know every detailed aspect that average people may disregard but a beginner may be afraid of starting the Internet.
