The importance of the net-based customer service in delivering supplementary after-sale services associated with product has been well documented. The strategic advantages of a well-implemented the net-based customer service are enhanced customer loyalty and higher lock-in of customers, and the resulting reduction in competition and the consequent increase in profits. However, not all customers utilize such the net-based customer service. This is partly due to the e-commerce divide, and partly due to privacy and security concerns of the customer for sharing personal information with firms. The limited level of customer adoption of the net-based customer service affects the firm profits and the customers' welfare. We use a game-theoretic model in which we model the net-based customer service system as a mechanism to enhance customers' loyalty. We find that an increase in adoption of the net-based customer service by the customer base is not always desirable for firms. and that customers who utilize such services are better off only when the overall adoption is limited.

The bracket tilt among automobile parts is weld parts which construct the column assembly bracket tilt of equipments and accurate dimension after welding is more essential than weldment strength. By the way, it is insufficient that systematic study about this parts which have an importance on welding deformation. The reason is that welding deformation is complex problem with shape, size, material of parts and welding sequence, conditions etc. For reduction and removal of welding deformation, therefore, it is necessary that the security of welding deformation data and systematic examination about equipment, costs, work environment, manufacturing process etc. It is all the better that the prediction of welding deformation using simulation of welding process by FEA is supplemented. In this study, the countermeasure for this welding deformation of bracket tilt is brought up through experimental inspection before the choice of the optimum welding conditions with minimum welding deformation by simulation of welding process.

This paper will explore the problem of domestic violence in the UK. It will begin by defining the problem and then set out estimates of the extent of the problem, while also examining the problems that are involved in measurement. It will then examine the policing strategies that have been put in place to tackle this problem, such as intelligence gathering, effective investigations, and risk management techniques. The paper will also highlight the importance of multi-agency involvement when dealing with domestic violence and the wide range of orders that have been created in order to help deal with this problem.

Data provenance is the background knowledge that enables a piece of data to be interpreted and used correctly within context. The importance of tracking provenance is widely recognized, as witnessed by significant research in various areas including e-science, homeland security, and data warehousing and business intelligence. In order to further advance the research on data provenance, however, one must first understand the research that has been conducted to date and identify specific topics that merit further investigation. In this work, we develop a framework based on semiotics theory to assist in analyzing and comparing existing provenance research at the conceptual level. We provide a detailed review of data provenance research and compare and contrast the research based on d semiotics framework. We conclude with an identification of challenges that will drive future research in this field.

As the era of e-navigation begins, the significance of harmonized collection, exchange, and integration of marine information conventional "ship-to-ship" and "ship-to-shore"/"shore-to-ship" has become more significant in ensuring safety and security at sea. This research aims to provide an internationally applicable list of Standard e-Navigation Phrases (SENP ) for communication in the e-Navigation environment, along with practical approaches to this. For this purpose, the importance of standardized communication phrases specific to e-Navigation will first be illustrated. In order to approach the e-Navigation phrases in a practical and pragmatic manner, means of compiling and processing authentic VHF linguistic data accumulated from one of the Korean ports, Ulsan, will be detailed. In addition, major outcomes to be considered in designing SENP will be suggested. Finally, future actions and a joint effort for the standardization of e-Navigation phrases among stakeholders will be sought.

The recent movement to deregulated and competitive electricity market changes the role of Security Constrained Optimal Power Flow (SCOPF) and increases the importance for real-time computation. communication, and on-line data control. As power systems tend to be operated more closely to their ultimate ratings, more rapid updates of telemetered data and faster solutions times are becomimg necessary to better track the changes in systems. This paper presents an on-line SCOPF application exploiting the state-of-art OPF tools and corresponding interfacing technologies. The significance of the proposed mechanism is demonstrated with a case study system.

With development of information communications and network environments security importance to the informations deepen as time goes. In this viewpoint, cryptosystem is developing but proportionally cracking and hacking technology is developing Therefore, in this paper we proposed and designed block cryptosystem with byte variable operation. Designed cryptosystem based on byte operation is safe than existed cryptosystem because it is not generate the fixed DC and LC characteristics. Additionally, proposed cryptosystem have high processing rate and authenticated operation. Therefore proposed cryptosystem is considered to many aid in the network fields.

Company which produce the latest plastic products of survival dimension for competitive power security productivity elevation activity hard do. But enterprises is lacking value elevation activity that customer among product special quality is thinking heftily and isn't grasping well adjusted impact factors. So, addition quality failure cost is produced. In this research, investigated impact factor and factors influencing most heftily in quality for productivity elevation. As a result, present example that serve to control well importance benevolence.

A person's residence is the primary environment which affects physical and emotional-gratification. Residential environments are very important to a person's quality of life. Because the age of society has rapidly increased, we must take a profound interest in the welfare and residences of the aged. While the government has begun to prepare for an aging society, the residential environments of the aged has not been fully considered. Because the welfare of the aged begins in the house, the term 'residence for the aged' is not limited to the physical space. Because residences for the old aged are included in various social policies such as family relations, social security, health care, safety etc, relevant policies for these residences must be prepared as rapidly as possible. This study-focused on both the importance of residences for the aged and the residential desires of the aged, and aims to propose planning criteria for the residences of the aged.

Power transmission lines have been playing a key role as the mainstay of national industry. When a power failure occurs, it can have severe effects on national security as well as national industry and economy. In this paper, we consider an insulator failure, which is one of the main causes of such a power failure. In spite of its importance, however, a shortage of manpower in the insulator maintenance field is getting more serious due to working environments with a high voltage and a high place. For this reason, a new active maintenance technique using a robot system is required to prevent such an insulator failure. In this paper, a new robot mechanism for insulator cleaning and inspection was developed. We confirmed its effectiveness through experiments.
