Integrated Blockchain and Cloud Computing Systems: A Systematic Survey, Solutions, and Challenges

Cloud computing is a network model of on-demand access for sharing configurable computing resource pools. Compared with conventional service architectures, cloud computing introduces new security challenges in secure service management and control, privacy protection, data integrity protection in distributed databases, data backup, and synchronization. Blockchain can be leveraged to address these challenges, partly due to the underlying characteristics such as transparency, traceability, decentralization, security, immutability, and automation. We present a comprehensive survey of how blockchain is applied to provide security services in the cloud computing model and we analyze the research trends of blockchain-related techniques in current cloud computing models. During the reviewing, we also briefly investigate how cloud computing can affect blockchain, especially about the performance improvements that cloud computing can provide for the blockchain. Our contributions include the following: (i) summarizing the possible architectures and models of the integration of blockchain and cloud computing and the roles of cloud computing in blockchain; (ii) classifying and discussing recent, relevant works based on different blockchain-based security services in the cloud computing model; (iii) simply investigating what improvements cloud computing can provide for the blockchain; (iv) introducing the current development status of the industry/major cloud providers in the direction of combining cloud and blockchain; (v) analyzing the main barriers and challenges of integrated blockchain and cloud computing systems; and (vi) providing recommendations for future research and improvement on the integration of blockchain and cloud systems.

Improvement Of Caregivers Ability to Care for Patients in Mentari Hati Social Institutions Tasikmalaya

Based on Riskedas data in 2013, the prevalence of mental disorders in Indonesia is about 6% of the population has emotional disorders and 1.7% of serious mental disorders. In West Java the prevalence reaches 1.6%, while in Tasikmalaya City there are 171 sufferers. Mental disorders can be caused by biological, psychological and socio-cultural factors, it can also be caused by inadequate provision of patient care, especially in small towns and villages. Patients with chronic mental disorders need care management that involves various elements in the healing process, such as family, community and caregivers. The role of care giver which is very influential in the patient's healing process, they are in charge of providing emotional support and the necessities of life. The complex problems in patient care caused many of them not to be well cared for. One of the phenomena was found at the Mentari Hati Social Institusion. The caregiver's low educational background, and lack of knowledge in care, are among the factors causing the ineffective treatment provided. For this reason, a mental nursing service management program is needed which is managed in a Community Mental Health Nursing (CMHN) program which aims to empower caregivers by providing consultation and education services, and providing information on mental health principles. The purpose of this community service activity is to improve the care giver's ability to care for mental patients.

Organizational Culture: The Key to Improving Service Management in Industry 4.0

Industry 4.0 can enhance the operational efficiency of the supply chain, but the current research mainly focuses on analytics and smart things. Many companies integrate their organizations more closely with data by adopting Industry 4.0, but this study found that some companies have changed their leadership, organizational, and customer relationships through the adoption of CPS. Industry 4.0 is a socio-technical system that should be explored in terms of management practices, employee feedback, and the cause-and-effect relationship between them. This study proposes a modeling framework using the Su-field analysis of TRIZ method (Theory of Inventive Problem Solving) and applies the Partial Least Squares Structural Equation Modeling (PLS-SEM) method to investigate the relationship between leadership, organizational culture, and service management in the Taiwan industry. The results show that the data analysis, CPS, IoT, and intelligent technologies of Industry 4.0 can facilitate connections within the value chain and increase agility in response to environmental changes. Companies must have a good organizational culture and provide the right incentives to gain the organizational commitment of their employees to implement Industry 4.0.

Semantic Interoperability in Internet of Things

The industry's internet of things (IoT) applications have drawn significant research attention in recent decades. IoT is a technology in which intelligent objects with sensors-enabled RFID tags, actuators, and processors communicate information to cater to a meaningful purpose in the industry. This way, IoT technology aims to simplify the distributed data collection in industrial practice, sharing and processing information and knowledge across many collaborating partners using suitable enterprise information systems. This chapter describes new methods with grounded knowledge representation techniques to address the needs of formal information modeling and reasoning for web-based services. The chapter presents a framework, apparel business decentralized data integration (ABDDI), which uses knowledge representation methods and formal languages (e.g., description logics – DLs) to annotate necessary business activities. This type of web service requires increased interoperability in service management operations.

Key Factors for Measuring Value Co-Creation in the Industrial Service Ecosystem

Managing and measuring value co-creation in industrial services are emerging themes from the perspective of industry and scientific research. Thus, this chapter aims to review the literature in order to identify the criteria for value co-creation management and measuring used to measure value co-creation in the industrial service ecosystem. To achieve this goal, the authors conducted a systematic literature review and a content analysis of the portfolio resulting from the review. Based on the findings, eight criteria were listed for managing value co-creation in the B2B (business-to-business) services sector. In addition, they identified a lack of limited integration and interdependence between the criteria shown in the literature for cooperative service management among companies.

Data were collected from August to October 2019, using an electronic questionnaire. Results: the prevalence of suicidal ideation among participants was 26.33%. In the final logistic regression model, only depressive symptoms were associated with suicidal ideation. Having symptoms of depression increased the chances of suicidal ideation 2.6 times. Conclusion: the high prevalence of suicidal ideation and its associated factors constitutes a situational diagnosis that demands the elaboration of public and institutional policies, focused on the promotion and attention to the mental health of the students.

The Impact of Overseas Training on the Performance of Bangladesh Civil Service: The Case of AIT Extension Training, Thailand

Public administration has to compete with private sectors in terms of quality service delivery to citizens. In this context, civil service training, especially overseas training, has been considered the most significant requirement to increase the performance of the Bangladesh Civil Service. This article tries to explore the impact of overseas training on the performance of the Bangladesh Civil Service. To achieve this objective, this study interviewed Bangladesh Civil Servants who participated Asian Institute Training (AIT) Extension training programme from 2016 to 2018. A mixed-method was applied to analyse the collected data. It found that Bangladesh Civil Servants, who have received AIT Extension training, were satisfied with the training management of AIT. Participants believed that such overseas training positively contributes to enhancing the performance of the Bangladesh Civil Service. However, this study also disclosed that fewer overseas training opportunities for young civil servants, lack of need-based training, and poor management of overseas training policy are the main obstacles in Bangladesh Civil service management. This article strongly recommends that there must be a detailed overseas training policy management and more collaboration with international training institutes to get better performance from the government officers in Bangladesh.
