Purpose - Nowadays customers have become empowered by information communication technologies. This state of customers has brought enormous pressure to bear on organizations, thus, organizations have to stay relevant, market-oriented and profitable. The insurance sector is one that is constantly challenged by its exposure to ICT and the associated need for e-services by myriad customers. With increasing competition in the health insurance environment, it is necessary for the sector to understand customer expectations and how they perceive the services offered. This study seeks to determine the role played by e-services in relation to customer satisfaction in health insurance industry in Botswana where a substantial investment has been made in the sector. Research design, data, and methodology - This study is conducted using two prominent medical aid schemes in Botswana namely BPOMAS and PULA. Subscribers of these medical schemes were the respondents whose views were sourced using both closed and open ended questionnaires. Systemic sampling technique was used to select the participants, while descriptive statistical techniques were mainly used to analyze socio-demographic data of the samples. Results - The results reveal that the level of usage of the medical insurance firm's website and email service is higher for PULA participants than for BPOMAS participants. Conclusions - The findings of this study have practical implications for managers who should understand customers' value perceptions regarding e-service quality in Botswana.

Instant messaging(IM) service is one of the useful communication means in the Intemet for exchanging simple messages between users. Usually, IM service is coupled with Presence service which provides status information of users. In this case, instant messages are sent and received directly between on-line users. Therefore, messages could not be exchanged when users are in off-line state. In this paper, We have implemented SIP based Instant Messaging System which includes message server that can store and manage instant messages. With this message server, messages could be exchanged legalness of user states. Furthermore, our system includes message waiting indication event package which provides useful informations about messages in the message server. And this system also includes the Caller Preference capabilities.

Data mashup is a web technology that combines information from multiple sources into a single web application. Mashup applications create a new horizon for new services, like environmental monitoring. Environmental monitoring is a serious tool for the state and private organizations, which are located in regions with environmental hazards and seek to gain insights to detect hazards and locate them clearly. These organizations utilize a data mashup to merge datasets from different Internet of multimedia things (IoMT) context-based services in order to leverage its data analytics performance and the accuracy of the predictions. However, mashup different datasets from multiple sources is a privacy hazard as it might reveal citizens specific behaviors in different regions. The ability to preserve privacy in mashuped datasets and at the same time provide accurate insights becomes a key success for the spread of mashup services. In this paper, we present our efforts to build a fog-based middleware for private data mashup (FMPM) to serve a centralized environmental monitoring service. The proposed middleware is equipped with concealment mechanisms to preserve the privacy of the merged datasets from multiple IoMT networks involved in the mashup application. Also, these mechanisms preserve the aggregates in the dataset to maximize the usability of information to attain accurate analytical results. We also provide a scenario for IoMT-enabled data mashup service and experimentation results.

Three-dimensional (3D) computed tomography image models are helpful in reproducing the maxillofacial area; however, they do not necessarily provide an accurate representation of dental occlusion and the state of the teeth. Recent efforts have focused on improvement of dental imaging by replacement of computed tomography with other detailed digital images. Unfortunately, despite the advantages of medical simulation software in dentofacial analysis, diagnosis, and surgical simulation, it lacks adequate registration tools. Following up on our previous report on orthognathic simulation surgery using computer-aided design/computer-aided manufacturing (CAD/CAM) software, we recently used the registration functions of a CAD/CAM platform in conjunction with surgical simulation software. Therefore, we would like to introduce a new technique, which involves use of the registration functions of CAD/CAM software followed by transfer of the images into medical simulation software. This technique may be applicable when using various registration function tools from different software platforms.

This study explored the socialization of novice Home Economics(HE) teachers employing a qualitative research method. Data was collected through in-depth interviews with four novice HE teachers from secondary schools. The collected data was analyzed inductively by NVivo, a kind of CAQDAS. The following analysis was organized around three stages of teachers' careers: first, as for influences on teacher socialization prior to formal teacher education, their experiences on 'apprenticeship of observation' provided them both positive and negative role models; second, as for the socialization role of pre-service teacher education, they mentioned that college courses were poorly connected to classroom realities with only a few helpful lectures on HE Education; third, as for socialization in the workplace and its culture, the novice HE teachers were confronted with many kinds of problems including isolation in the classroom, in-service training programs not geared to novices, an overwhelming workload, and so on. Because of these problems, they yearned for and also formed networks with other HE teachers in order to overcome their limitations. The findings supported the notion that interactive and dialectical processes exist during all stages of HE teachers' careers. This study suggests that the teacher in-service training programs are more relevant, and that the introduction of mentoring programs and classroom manuals and teacher manuals would be helpful in practice. These innovations call for cooperation between universities and provincial offices of education for teachers' professional success in teacher socialization.

Automatic Repeat reQuest (ARQ) is a very effective technique against transmission error at the medium access control (MAC) layer. An erroneous MAC protocol data unit can be typically retransmitted within a given limit. In order to improve the IP-level performance, which directly affects the user-perceived quality-of-service (QoS), we propose a new truncated ARQ strategy, called MAC service data unit-based ARQ (S-ARQ), where the finite number of opportunities for retransmissions are shared by multiple fragments out of an IP datagram. We describe how SARQ can be implemented in a practical system, and then propose another variant of S-ARQ employing a functionality called early detection of failure. Basically, we evaluate the performance of SARQ in two different manners. First, assuming i.i.d. error process, we analyze both the probability of the delivery failure and the average delay of IP datagram. Then, we assess the performance of S-ARQ via simulation over a 2-state Markov channel.

Multiple convenience features have been getting installed in recently released cars. However, the control of them has many uncomfortable matters yet. To resolve them, it is needed to study how to use easier the convenience features and control them remotely. Currently, wide range of convergence services are being released in various industries by using smartphone and smartphones with its state-of-the-art functions also are being released. In this paper, we design and implement smartphone-based applications for controling the vehicle's convenience features to control the vehicle convenience features with smartphone. To do this, we configure CAN (Controller Area Network) communication between the vehicle's various convenience features, and establish MCU (Micro Controller Unit) to control each feature. We also connect between the MCU and smartphones to make them available for the remote control. We can control lights, turn signals, audio, windows, air conditioner, and so on with the implemented smartphone-based control service of vehicle's convenience features using CAN remotely.

Recently, the intelligent service robot is applied for the purpose of guiding the building or providing information to the visitors of the public institution. The intelligent robot which is on development has a sensor to recognize its location at the bottom of it. Four wheels which are arranged in the form of a lozenge support the weight of the components and structures of the robot. The operating environment of this robot is restricted at the uneven place because the driving part and internal structure is designed in one united body. The impact from the ground is transferred to the internal equipments and structures of the robot. This continuous impact can cause the unusual state of the precise components and weaken the connection between each structural part. In this paper, a suspension system which can be applied to the intelligent robot is designed. The dynamic model of the robot is created, and the driving characteristics of the actual robot and the robot with suspension are compared. The road condition which the robot can operate is expanded by the application of the suspension system. Additionally, the suspension system is optimized to reduce the impact to the robot components.
