  • With rapid development of ICT (Information and Communications Technology), new services by the convergence of mobile network and application technology began to appear. Today, smart phone with new ICT convergence network capabilities is exceedingly popular and very useful as a new tool for the development of business opportunities. Previous studies based on Technology Acceptance Model (TAM) suggested critical factors, which should be considered for acquiring new customers and maintaining existing users in smart phone market. However, they had a limitation to focus on technology acceptance, not value based approach. Prior studies on customer's adoption of electronic utilities like smart phone product showed that the antecedents such as the perceived benefit and the perceived sacrifice could explain the causality between what is perceived and what is acquired over diverse contexts. So, this research conceptualizes perceived value as a trade-off between perceived benefit and perceived sacrifice, and we need to research the perceived value to grasp user's continuous intention to use of smart phone. The purpose of this study is to investigate the structured relationship between benefit (quality, usefulness, playfulness) and sacrifice (technicality, cost, security risk) of smart phone users, perceived value, and continuous intention to use. In addition, this study intends to analyze the differences between two subgroups of smart phone users by the degree of personal innovativeness. Personal innovativeness could help us to understand the moderating effect between how perceptions are formed and continuous intention to use smart phone. This study conducted survey through e-mail, direct mail, and interview with smart phone users. Empirical analysis based on 330 respondents was conducted in order to test the hypotheses. First, the result of hypotheses testing showed that perceived usefulness among three factors of perceived benefit has the highest positive impact on perceived value, and then followed by perceived playfulness and perceived quality. Second, the result of hypotheses testing showed that perceived cost among three factors of perceived sacrifice has significantly negative impact on perceived value, however, technicality and security risk have no significant impact on perceived value. Also, the result of hypotheses testing showed that perceived value has significant direct impact on continuous intention to use of smart phone. In this regard, marketing managers of smart phone company should pay more attention to improve task efficiency and performance of smart phone, including rate systems of smart phone. Additionally, to test the moderating effect of personal innovativeness, this research conducted multi-group analysis by the degree of personal innovativeness of smart phone users. In a group with high level of innovativeness, perceived usefulness has the highest positive influence on perceived value than other factors. Instead, the analysis for a group with low level of innovativeness showed that perceived playfulness was the highest positive factor to influence perceived value than others. This result of the group with high level of innovativeness explains that innovators and early adopters are able to cope with higher level of cost and risk, and they expect to develop more positive intentions toward higher performance through the use of an innovation. Also, hedonic behavior in the case of the group with low level of innovativeness aims to provide self-fulfilling value to the users, in contrast to utilitarian perspective, which aims to provide instrumental value to the users. However, with regard to perceived sacrifice, both groups in general showed negative impact on perceived value. Also, the group with high level of innovativeness had less overall negative impact on perceived value compared to the group with low level of innovativeness across all factors. In both group with high level of innovativeness and with low level of innovativeness, perceived cost has the highest negative influence on perceived value than other factors. Instead, the analysis for a group with high level of innovativeness showed that perceived technicality was the positive factor to influence perceived value than others. However, the analysis for a group with low level of innovativeness showed that perceived security risk was the second high negative factor to influence perceived value than others. Unlike previous studies, this study focuses on influencing factors on continuous intention to use of smart phone, rather than considering initial purchase and adoption of smart phone. First, perceived value, which was used to identify user's adoption behavior, has a mediating effect among perceived benefit, perceived sacrifice, and continuous intention to use smart phone. Second, perceived usefulness has the highest positive influence on perceived value, while perceived cost has significant negative influence on perceived value. Third, perceived value, like prior studies, has high level of positive influence on continuous intention to use smart phone. Fourth, in multi-group analysis by the degree of personal innovativeness of smart phone users, perceived usefulness, in a group with high level of innovativeness, has the highest positive influence on perceived value than other factors. Instead, perceived playfulness, in a group with low level of innovativeness, has the highest positive factor to influence perceived value than others. This result shows that early adopters intend to adopt smart phone as a tool to make their job useful, instead market followers intend to adopt smart phone as a tool to make their time enjoyable. In terms of marketing strategy for smart phone company, marketing managers should pay more attention to identify their customers' lifetime value by the phase of smart phone adoption, as well as to understand their behavior intention to accept the risk and uncertainty positively. The academic contribution of this study primarily is to employ the VAM (Value-based Adoption Model) as a conceptual foundation, compared to TAM (Technology Acceptance Model) used widely by previous studies. VAM is useful for understanding continuous intention to use smart phone in comparison with TAM as a new IT utility by individual adoption. Perceived value dominantly influences continuous intention to use smart phone. The results of this study justify our research model adoption on each antecedent of perceived value as a benefit and a sacrifice component. While TAM could be widely used in user acceptance of new technology, it has a limitation to explain the new IT adoption like smart phone, because of customer behavior intention to choose the value of the object. In terms of theoretical approach, this study provides theoretical contribution to the development, design, and marketing of smart phone. The practical contribution of this study is to suggest useful decision alternatives concerned to marketing strategy formulation for acquiring and retaining long-term customers related to smart phone business. Since potential customers are interested in both benefit and sacrifice when evaluating the value of smart phone, marketing managers in smart phone company has to put more effort into creating customer's value of low sacrifice and high benefit so that customers will continuously have higher adoption on smart phone. Especially, this study shows that innovators and early adopters with high level of innovativeness have higher adoption than market followers with low level of innovativeness, in terms of perceived usefulness and perceived cost. To formulate marketing strategy for smart phone diffusion, marketing managers have to pay more attention to identify not only their customers' benefit and sacrifice components but also their customers' lifetime value to adopt smart phone.

  • 클라우드 컴퓨팅 서비스는 가상화 기술을 이용하여 물리적인 IT 자원을 VM 단위로 사용자들에게 비용을 받고 제공하는 서비스이다. 그 중 클라우드 컴퓨팅 기반 가용 자원 경매 모델은 서비스 제공자의 가용 자원을 경매를 통해서 사용자들에게 제공 하는 서비스이다. 서비스 이용자들은 제한 시간 안에 그들의 작업을 처리하기 위해 서비스 제공자에게 자원 이용에 대한 입찰가격을 제시하고 낙찰 가격 보다 높은 경우 자원을 제공 받는다. 본 논문에는 Amazone EC2에서 서비스 이용자의 작업을 완료하는데 요구되는 스팟 인스턴스에 대한 총 경비를 최소화하는 입찰 기법을 제안한다. 일반적으로, 서비스 이용자는 자원을 할당 받기 위해 높은 입찰 가격을 제시할 것이고, 그에 따라 낙찰 가격이 높아짐으로써 서비스 이용자의 실제 작업 비용은 높아지게 된다. 따라서 제안 입찰 기법을 이용하여 낙찰 가격을 낮춤으로써 서비스 이용자의 총 경비를 최소화 할 수 있다. 제안 기법의 성능 분석을 위해 실제 데이터를 이용하여 낙찰 가격과 실제 총 경비를 계산하고, 실제 낙찰 가격 기반의 입찰 기법과 비교함으로써 제안 기법의 성능을 입증하였다.

  • 새로운 제도나 경영전략 등이 성공적으로 정착되어 조직의 성과제고로 연계되기 위해서는 내재화과정이 반드시 필요하다. 성공적인 내재화를 위해서 많은 기관에서 가장 많이 활용하는 방법은 교육방법 및 커뮤니케이션 전략이라고 할 수 있다. 그러나 교육이나 커뮤니케이션을 원활하게 진행하기 위해서는 조직구성원들간 신뢰와 협력지향적인 문화 등 다양한 측면에서의 융합전략이 뒷받침되어야만 한다. 본 연구에서는 특정 공공기관의 직원들을 대상으로 새로이 도입한 조직비전, 핵심가치 등에 대한 내재화 정도 및 조직문화 등에 대해 조사해보고, 성공적인 경영전략 내재화 방안을 제시하고자 하였다. 우선, 경영전략 강화 교육을 위해서는 반복학습을 통해 자주 노출시키고 자주 대화하는 방법이 효과적이다. 이를 위해 집합교육과 이러닝 등 집중적인 교육방법을 병행해야 한다. 둘째, 의사소통의 활성화를 위해서는 기관장이 직원들과의 내재화를 위한 의사소통에 관심을 기울여야 하며, 다양한 방법의 의사소통 전략을 세워야 할 것이다. 끝으로, 조직문화의 변화를 위해서는 동료들간 개방적이고 협조적인 문화구축을 위한 비공식적인 의사소통의 장을 자주 마련하고 인적네트워크의 양적, 질적 확대를 지원해주어야 한다.

  • The purposes of this study were to evaluate students' performance by student self-evaluation and by educators in the field respectively after an internship program, to analyze the gap between the two groups, to identify students, satisfaction and behavior intention and to suggest the direction of an internship program in the Food and Nutrition Department. The results of the survey of 133 students and 129 educators as follows: a majority of the program periods was two weeks and most students experienced an internship program once. Both students and educators evaluated highly in 'I (Students) worked faithfully as a trainee.', 'I (Students) observed the rules and cooperated with other colleagues.', 'I (Students) behaved with clear and polite words.'. Educators estimated higher than students in all items, especially in 'I (Students) prepared and planned needs for internship in advance.' (p<0.00l), 'I (Students) got on close terms with the staff and enjoyed their confidence.' (p<0.001). For details of the internship program, students were satisfied with 'professors' roles' (3.95), 'educator's abilities' (3.85), 'treatment of students' (3.84) but dissatisfied with 'pay to students' (1.94). Students perceived that an internship program was helpful to understand their major (4.37) and to decide upon their job (4.17). They had an intention to participate in another internship program (4.63) and to recommend to their juniors to participate in a program (4.73). Students had a diversity of opinions for program periods and most wanted to participate two times in summer or winter vacation of junior. Therefore an internship program needs curriculum in the food and nutrition department and the continuous and active cooperation between university and institutions would lead to an effective and efficient internship program.

  • Mobile Crowdsourcing (MCS) has become an emerging paradigm evolved from crowdsourcing by employing advanced features of mobile devices such as smartphones to perform more complicated, especially spatial tasks. One of the key procedures in MCS is to collect answers from mobile users (workers), which may face several security issues. First, authentication is required to ensure that answers are from authorized workers. In addition, MCS tasks are usually location-dependent, so the collected answers could disclose workers' location privacy, which may discourage workers to participate in the tasks. Finally, the overhead occurred by authentication and privacy protection should be minimized since mobile devices are resource-constrained. Considering all the above concerns, in this paper, we propose a lightweight and privacy-preserving answer collection scheme for MCS. In the proposed scheme, we achieve anonymous authentication based on traceable ring signature, which provides authentication, anonymity, as well as traceability by enabling malicious workers tracing. In order to balance user location privacy and data availability, we propose a new concept named current location privacy, which means the location of the worker cannot be disclosed to anyone until a specified time. Since the leakage of current location will seriously threaten workers' personal safety, causing such as absence or presence disclosure attacks, it is necessary to pay attention to the current location privacy of workers in MCS. We encrypt the collected answers based on timed-release encryption, ensuring the secure transmission and high availability of data, as well as preserving the current location privacy of workers. Finally, we analyze the security and performance of the proposed scheme. The experimental results show that the computation costs of a worker depend on the number of ring signature members, which indicates the flexibility for a worker to choose an appropriate size of the group under considerations of privacy and efficiency.

  • The purpose of this study was to establish the role of master gardener coordinators and develop an education program to enhance their job competencies. To analyze and develop the new job of master gardener coordinator, we used the CBC method for curriculum development. The research findings can be summarized as follows. The analysis result of need and importance of education based on the performance level and demand level revealed 20 core competencies, which were classified into organizational education, learning by experience, individual learning, low-priority competencies for program development, with focus on the importance and need for education. The 17 courses are comprised of Eastern and Western Garden History, Understanding of Community Garden, Garden Aesthetics and Environmental Design, Master Gardener's Mission & Management, Garden Plants, and Garden Design and Practice etc. and the curriculum is 33 hours in total. The master gardener coordinator education program was conducted on 73 rural extension workers and the curriculum was evaluated by those who completed the program. The overall satisfaction was 4.29 and 97.1% of the trainees decided that the program would help them perform their duties. The analysis result discovered that all 20 core competencies increased after the program. As a result of conducting contingent valuation to determine the value of the program, willingness to pay (WTP) per hour was KRW 33,223 and the total WTP was KRW 1.096 million, which, when multiplied by 73 participants, is approximately KRW 80.008 million. This is relatively higher than the budget used (KRW 22.943 million), indicating that the program is worth it.
