Mobile phone-related industries have been mainly concentrated on attracting the new customers and increasing the market share such as for the aggressive marketing activities, but it is the time to find an effective strategy to preserve existing customers since the mobile phone market had already reached the saturation. In this study, the properties of mobile phone that influence on the choice of handset and telecom company were analyzed. General properties of respondents were explored and the mobile phone properties were grouped by common factors. And analyzed the effect of factors on customer satisfaction with structural equation model. 10.4% of respondents are used their handset more than two years and 48.7% wanted to purchase other manufacturer's handset if they repurchase mobile phone. These results might come form the fact that the life cycle of mobile phone become shorter by the heating competition in mobile phone market and, to some degree, the influence of smart phone which recently become globally popular. Four factors, 'Hardware Quality', 'Practicality', 'Convergence Functions' and 'Level of Awareness', are induced from the mobile phone properties. In Structural Equation Model analysis, 'Hardware Quality' and 'Practicality' have significant and positive effects on Customer Satisfaction. But, 'Awareness' such as brand and trend appeared quite less influence on the customer satisfaction.

Establishing a financial independence is essential for sustainable growth of social enterprises. In this vein, this study investigated the key factors that affect customer loyalty about the products or services provided by social enterprises. Commitment and trust in social enterprises were considered as main factors affecting customer loyalty. We also examined the effects of functional, hedonic and social value about the products or services of social enterprises on purchasing decision-making processes. The research model analysis was conducted on 204 consumers using social enterprises in Dong-gu, Daegu. The analysis of research model has shown that commitment and trust had a significant impact on customer loyalty about the product or service of those enterprises. Functional value did not have a significant effect on commitment, while it had a significant effect on trust. Hedonic value had a significant impact on both commitment and trust. Social value had a significant effect on commitment, but not on trust. Value congruence had a significant effect on both commitment and trust. Based on the our findings, it is expected that it would help establish operational and marketing strategies to improve competitiveness in products and services of social enterprises.

This study investigated that customer satisfaction based on the effects of perceived value (innovative value, practical value, symbolic value) and innovation characteristics (innovative resistance, visibility) of wearable healthcare device users on purchase attitude. A survey was conducted on actual users who are currently using wearable healthcare devices, and the final 201 copies were analyzed using SPSS 25 and SmartPLS 3.0. The summary of research results is following here. First, it was found that the perceived values, innovative and practical values had a positive (+) effect on the user's purchasing attitude, while symbolic values did not affect the user's purchasing attitude. Second, among the innovation characteristics, innovation resistance was came out negative (-) effect on the user's purchasing attitude, and among the innovation characteristics, visibility did not affect the user's purchasing attitude.

Unlike most researches that focus on single manufacturer or single buyer, this research studies the cooperation policy for two participants of supply chain such as single vendor and single buyer. Especially, this paper deals with single vendor-single buyer integrated-production inventory problem. If the buyer orders products, then the vendor will start to make products and then the products will be shipped from the vendor to the buyer many times. The buyer is supposed to order again when the buyer's inventory level hits reorder point during the last shipment and this cycle keeps repeated. The buyer uses continuous review inventory policy and customer's demand is assumed to be probabilistic. The contribution of this paper is to present a mixed approach and derive its cost function. The existing policy assumes that the size of shipping batch from single vendor to single buyer is increasing, called Type 1, or constant, called Type 2. In mixed approach, the size of shipping batch is increasing at the beginning part of the cycle, and then its size is constant at the ending part of the cycle. The number of shipping for Type 1 and Type 2 in a cycle in mixed approach is determined to minimize total cost. The relationship between parameters, for example, the holding cost per product, the set up cost per order, and the shortage cost per item and decision variables such as order quantity, safety factor, the number of shipments, and shipment increasing factor is figured out via sensitivity analysis. Finally, it is statistically proved that the mixed approach is superior to the existing approaches.

The Internet succeeded because of the end-to-end principle which allowed anyone to add functionality to the network. However, as the internet is increasingly becoming the platform for smart IT applications such as VoIP, IPTV, Cloud Computing and Smart Phone, networks are now under increasing strain of traffic congestion and the absence of quality of service insurances. To date, the debate over internet rules has focused on network neutrality rather than network efficiency. This article emphasizes the well-functioning role of market mechanism for the efficient use and further development of the network. To maximize the value of the network, this article proposes a differential treatment to packets based on customer types, and a two-part tariff pricing rule to secure funding to expand and upgrade networks.

In this paper, we discuss a discrete-time queueing system with dyadic server control policy that combines workload control and multiple vacations. Customers arrive at the system with Bernoulli arrival process. If there is no customer to serve in the system, an idle single server spends a vacation of discrete random variable V and returns. The server repeats the vacation until the total service time of waiting customers exceeds the predetermined workload threshold D. In this paper, we derived the steady-state workload distribution of a discrete-time queueing system which is operating under a more realistic and flexible server control policy. Mean workload is also derived as a performance measure. The results are basis for the analysis of system performance measures such as queue lengths, waiting time, and sojourn time.
