Blockchain-Based Distributed Information Hiding Framework for Data Privacy Preserving in Medical Supply Chain Systems
Medical supply chain communication networks engender critical information and data. Notably in the COVID era, inner personal and private information is being shared between healthcare providers regarding the medical supply chain. In recent years, multiple cyber-attacks have targeted medical supply chain communication networks due to their lack of security measures. In the era where cyber-attacks are cheaper and easier due to the computational power and various algorithms available for malicious uses, security, and data privacy requires intensive and higher measures. On the other hand, Information Hiding Techniques (IHT) compromise various advanced methods to hide sensitive information from being disclosed to malicious nodes. Moreover, with the support of Blockchain, IHT can bring higher security and the required privacy levels. In this paper, we propose the implementation of Blockchain and smart contract with the information hiding technique to enhance the security and privacy of data communication in critical systems, such as smart healthcare supply chain communication networks. Results show the feasibility of the framework using Hyperledger smart contract along with the desired security level.

Drug traceability and transparency in medical supply chain using blockchain for easing the process and creating trust between stakeholders and consumers
Without a proper mechanism to track and authenticate drugs, both stakeholder and consumer experience dilemmas. The dilemmas arise between stakeholders and consumers are related to of coordination, inventory management, human resource dependency, order management, stock management, expiry of medicines data etc. Stakeholders are unable to analyse the demands, hence becoming incapable of optimizing their production and storage. Likewise, a consumer remains suspicious about the authenticity of the drug. A medical supply chain promotes updating medicine status at each checkpoint, reducing the disputes caused by medicine ' s unseen journey. In the current market, medical supply chains are present, but they are centralized. A centralized medical supply chain is typically tedious and expensive to maintain and does not provide adequate features to analyse markets. Above all, it brands merely a certificate to prove the authenticity of a drug. However, by using a blockchain platform, the medical supply chain problems can be solved efficiently. This blockchain-based medical supply chain’s key feature is to system stores all the medicine batch ' s transfer history. First, a pharmaceutical company is permitted to register a medicine. After the manufacturing of a registered medicine, a batch-manager uploads its details on the platform ' s network. Hereafter, any further exchange of this batch needs both sender and receiver ' s approval. Only after the successful completion of this procedure, an exchange occurs. A corresponding exchange transaction is permanently stored on the network. This sequence shapes the system to follow a systematic order and eliminates the possibility of a third-person fraud. Lastly, we made a DApp (Decentralized Application) for the tracking of the medical supply chain. A medical supply chain built on the blockchain provides immutability, transparency, automation, and integrity. This paper aims to introduce a model to maintain medical supply chain records on the blockchain while explaining blockchain technology. Moreover, the blockchain platforms and their dependencies are explained lucidly. The medical supply chain’s implementation and design are performed using smart contracts, Web3.js library, and JavaScript. Furthermore, the system is tested on both a local network, the Truffle suite, and the Kovan test network. In the future, the use of IoT inculcating integrated chip that can automatically update a batch’s location, temperature, and other physical conditions periodically can be developed.

The influence of dynamic capabilities on hospital-supplier collaboration and hospital supply chain performance
Purpose
The purpose of this paper is to explore the influence of hospital’s visibility for sensing (VFS), learning, coordinating and integrating on hospital-supplier collaboration. Second, it explored the influence of hospital-supplier collaboration on hospital supply chain performance. The author also explored how the technology orientation of the medical chain units influences the above linkages.
Design/methodology/approach
The study adopted a multi-unit study of different hospital supply chains. Consequently, perceptual data were gathered from seven dominant entities in a typical medical/hospital supply chain: hospitals and clinics, accommodation (i.e. hotels), chemistry and pharmaceutical, marketing/public relations/promotion, medical equipment manufacturers, food and beverage and insurance. The responses were gathered using e-mail survey and were analyzed using structural equation modeling.
Findings
Based on 192 completed responses, the author found positive influences of VFS, learning and integrating on hospital-supplier collaboration and a positive impact of hospital-supplier collaboration on hospital supply chain performance. An insignificant influence of hospital’s visibility for coordinating was noted on hospital-supplier collaboration. The study argued hospitals to invest more for enriching their dynamic capabilities to diagnose the changes in the environment so as to sustain their collaborative relationships leading to positive performance implications.
Originality/value
The study is the foremost to investigate the effects of hospital’s dynamic capabilities on its collaborative efforts with its key supplier and their influence on hospital supply chain performance. Also the study is foremost in exploring the importance of technology orientation on hospital dynamic capabilities and hospital-supplier collaboration. An important contribution of the research is the conceptualization of supply chain visibility core components (visibility of sensing, visibility of learning, visibility of coordinating and visibility of integrating) in the context of hospital supply chains.

An Advanced Study of Urban Emergency Medical Equipment Logistics Distribution for Different Levels of Urgency Demand
At the early stage of a major public health emergency outbreak, there exists an imbalance between supply and demand in the distribution of emergency supplies. To improve the efficiency of emergency medical service equipment and relieve the treatment pressure of each medical treatment point, one of the most important factors is the emergency medical equipment logistics distribution. Based on the actual data of medical equipment demand during the epidemic and the characteristics of emergencies, this study proposed an evaluation index system for emergency medical equipment demand point urgency, based on the number of patients, the number of available inpatient beds, and other influencing factors as the index. An urban emergency medical equipment distribution model considering the urgency of demand, the distribution time window, and vehicle load was constructed with the constraints. Wuhan, Hubei Province, China, at the beginning of the outbreak was selected as a validation example, and the Criteria Importance Though Intercriteria Correlation (CRITIC) method and the genetic algorithm were used to simulate and validate the model with and without considering the demand urgency. The results show that under the public health emergencies, the distribution path designed to respond to different levels of urgency demand for medical equipment is the most efficient path and reduces the total distribution cost by 5%.

Interruption Risk Propagation and Resilience Evaluation of Supply Chain of Emergency Medical Supplies Under Information Sharing Mechanism
In the new context of information sharing to reshape the supply chain’s interruption risk propagation mechanism, this paper focuses on the interruption risk propagation and resilience of the supply chain of emergency medical supplies in the background of emergencies. Firstly, an emergency supply chain’s risk propagation model under information sharing is proposed by combining the information sharing mechanism with the supply chain’s risk propagation theory. Secondly, an interruption risk propagation model for the supply chain of emergency medical supplies based on a Bayesian Network is constructed, and the do-calculus technique is introduced to transform the intervention effect of information sharing into the quantification of the supply chain’s risk probability. Thirdly, a system dynamics method is used to construct a supply chain model for emergency medical supplies, which takes into account different interruption scenarios caused by emergencies and evaluates the supply chain’s resilience through the key variable “demand fulfillment rate” in the model. The results of the study indicate that the impact of different types of interruption scenarios on supply chain resilience varies significantly. Information sharing can effectively reduce the negative impact of interruption risk. This study provides theoretical basis and practical guidance for improving the resilience of the supply chain of emergency medical supplies, which is of great significance for maintaining social stability and promoting the sustainable development of the public health system.
