The popularization of smart phones changes the usage patterns of mobile communication from voice-centric to data-centric communication. The demand for wireless data communications is rapidly increasing, and thus the need for expanding infrastructure for mobile communication is also rapidly increasing. In this paper, we propose a scheme for reducing the cost for the mobile communication infrastructure by exploiting opportunistic networks in dissemination of multimedia contents. By using this scheme, the large portion of the cost for mobile communication infrastructure could be saved, and the need of users for multimedia contents could be also fulfilled. Our scheme is evaluated using agent-based simulations. The simulation results show that about 70% of mobile communication can be replaced with the data communication through opportunistic networks.

Purpose: To determine traits related to pregnancy and delivery, length of stay, health care cost, postpartum discomfort, and satisfaction with medical service of puerperas giving birth in midwifery clinic and hospitals. Methods: This study used a comparative survey design. Data were collected from a total of 140 postpartum mothers composed of 70 mothers who gave births in two hospitals and another 70 mothers who delivered in one midwifery clinic. Results: Delivery in midwifery clinic had higher Apgar score at 1 minute and 5 minutes after birth than hospital. Those who delivered in midwifery clinic had shorter stay in the clinic, fewer health care cost, less postpartum discomfort in physical, environmental, social, and cultural areas, higher satisfaction with medical services than those who delivered in hospitals. Conclusion: Results of this study can be used as a basis for studies on giving birth in midwifery clinic and hospitals. They might increase the autonomy of women in giving birth with positive effect on the delivery experience of the mother and her spouse.

Purpose: This study is to investigate the causal relationship between franchise headquarters' franchise cost and franchise satisfaction and management performance, and to verify the structural relationship between franchise cost and corporate permanence. Research design, data and methodology: The data were collected from 200 medium-sized franchisees in Seoul and analyzed using confirmatory factor analysis (CFA) to test the validity of the measurement model and the structural equation model (SEM) to identify the impact of franchise costs on corporate performance with the Amos 28.0 program. Result: Franchise costs were found to have a negative effect on franchise satisfaction and corporate permanence. It was confirmed that franchise satisfaction had a significant positive effect on management performance and corporate permanence. Franchise costs had a sequential mediating effect on franchise satisfaction and management performance, which had a significant impact on corporate permanence. Conclusions: This study expanded the theoretical scope by applying the expectation confirmation theory to corporate transactions. In addition, the franchise headquarters proposes ways to create a culture of franchise business with trust by presenting appropriate franchise costs to improve management performance and corporate permanence through franchise satisfaction.

The purpose of this research is to investigate the factors that impact customer satisfaction and loyalty in mobile payment services. Specifically, this research (1) studies the influence of company reputation on customer satisfaction and loyalty, (2) examines service quality dimensions that increase customer satisfaction, and (3) assesses switching barriers as moderators in influencing customer loyalty. Findings of this empirical research reconfirm the point of view that company reputation, service quality, and switching barriers are crucial for customer satisfaction in mobile payment services. The research methodologies that were used to verify the hypothesis in this study included customized surveys and structural equation modeling. The results demonstrated that company reputation significantly affects customer satisfaction and loyalty. Additionally, the results indicated that only two of the five total service qualities, ease of use and the security/privacy qualities, have positive influences on customer satisfaction. Customer satisfaction has also proven to be a significant influence on loyalty. Lastly, the results showed that among the factors of switching barriers, the factors of lost performance costs, sunk costs, setup costs, the attractiveness of alternatives, and service recovery have moderating effects on the relationships between customer satisfaction and loyalty. Base on the results, this research recommends that firms aim at devising integrated strategies that make switching barriers act as complements to customer satisfaction.

The berth and crane scheduling problem in a container terminal encompasses the whole process of assigning berth to each ship, determining the duration of berthing, assigning container cranes to each ship, and determining the specific start and end time of each crane service, for all the ships scheduled to be arriving at the terminal during a certain scheduling horizon. This problem is basically a constraint satisfaction problem in which cranes and berths should be assigned in such a way that all the spatial and temporal constraints are satisfied without any interference. However, it is also an optimization problem because the requested arrival and departure time should be met for as many of the scheduled ships as possible, while the operation cost of the terminal should be minimized. In this paper, we present an effective and efficient approach to solving this type of problem, which combines constrain satisfaction search and heuristic repair. We first employ a constraint satisfaction search to find a feasib1e solution. Then, the feasible solution is modified to a more optimal one by iteratively applying our heuristic repair operations within the framework of constraint satisfaction search. Experimental results with a real data from Pusan East Container Terminal showed that our approach can derive a schedule of satisfactory quality in a very short time.

In order to induce users to purchase excellent products in the water industry that satisfy the technical standards of excellent products, in this study, it is to present the advantages of the cost aspect of the pumps as the objective basis. It will be to promote technology development of domestic water companies and to create a virtuous cycle structure in the water industry. In order to present an objective basis for the merits in terms of cost, an economic evaluation was conducted through life cycle cost analysis. For the LCC analysis, initial cost (pump cost and installation cost), operation cost (energy cost and maintenance cost) and demolition cost (disposal cost and residual value) are searched and calculated. As the results of comparison on two capacity of pumps, the energy cost of the excellent pump is 212 million KRW lower than the that of general pump in the large pump. The cost of excellent pump was 17 million KRW lower than that of general pump in small capacity pump. As the results of sensibility test, if the product is developed in the direction of improving pump efficiency and increasing the replacement cycle of consumables, it is predicted that the effect on LCC will be large.
