Open Source Software Policy Options for NASA Earth and Space Sciences
Modern science is ever more driven by computations and simulations. In particular, the state of the art in space and Earth science often arises from complex simulations of climate, space weather, and astronomical phenomena. At the same time, scientific work requires data processing, presentation, and analysis through broadly available proprietary and community software.1 Implicitly or explicitly, software is central to science. Scientific discovery, understanding, validation, and interpretation are all enhanced by access to the source code of the software used by scientists.
This report investigates and recommends options for NASA's Science Mission Directorate (SMD) as it considers how to establish a policy regarding open source software to complement its existing policy on open data. In particular, the report reviews existing data and software policies and the lessons learned from the implementation of those policies, summarizes community perspectives, and presents policy options and recommendations for implementing an open source software policy for NASA SMD.

‘Fit-for-purpose?’ – challenges and opportunities for applications of blockchain technology in the future of healthcare
Blockchain is a shared distributed digital ledger technology that can better facilitate data management, provenance and security, and has the potential to transform healthcare. Importantly, blockchain represents a data architecture, whose application goes far beyond Bitcoin – the cryptocurrency that relies on blockchain and has popularized the technology. In the health sector, blockchain is being aggressively explored by various stakeholders to optimize business processes, lower costs, improve patient outcomes, enhance compliance, and enable better use of healthcare-related data. However, critical in assessing whether blockchain can fulfill the hype of a technology characterized as ‘revolutionary’ and ‘disruptive’, is the need to ensure that blockchain design elements consider actual healthcare needs from the diverse perspectives of consumers, patients, providers, and regulators. In addition, answering the real needs of healthcare stakeholders, blockchain approaches must also be responsive to the unique challenges faced in healthcare compared to other sectors of the economy. In this sense, ensuring that a health blockchain is ‘fit-for-purpose’ is pivotal. This concept forms the basis for this article, where we share views from a multidisciplinary group of practitioners at the forefront of blockchain conceptualization, development, and deployment.

Evaluation and Exploration on the Effect of the Management of Chronic Obstructive Pulmonary Disease in Rural Areas through an Internet-Based Network Consulting Room
Objective: This study aims to improve the management quality of chronic obstructive pulmonary disease (COPD) in rural areas. Methods: Two hundred forty discharged COPD patients were divided into an intervention group and a control group. In the intervention group, 120 patients established contact with doctors through the network consulting room, i.e., the doctor’s mobile platform, and were managed through video, voice, and text by the doctors, kept close contact with the doctors after discharge (education, consultation), and received electronic prescriptions, and drugs were sent to the patients’ door by online retailers. The patients in the control group were managed in the traditional manner. One year later, the predicted forced expiratory volume in 1 s (FEV1)%, FEV1/forced vital capacity (FVC), and CAT scores and the number of rehospitalized patients were compared between these 2 groups. Results: After 1 year of follow-up, the predicted FEV1% and the FEV1/FVC ratio were significantly higher in the intervention group than in the control group (p < 0.05). CAT scores were lower for patients in the intervention group than for those in the control group after 1 year of follow-up (p < 0.05). After 1 year of follow-up, 22 (18.33%) patients were rehospitalized in the intervention group and 58 (48.33%) patients were rehospitalized in the control group (p < 0.05). Conclusion: Doctors can improve the quality of life of patients with COPD and reduce the number of rehospitalizations through use of the network consulting room.

Wars of Disruption and Resilience
Increasingly, the power of a large, complex, wired nation like the United States rests on its ability to disrupt would-be cyber attacks and to be resilient against a successful attack or recurring campaign. Addressing the concerns of both theorists and those on the national security front lines, Chris C. Demchak presents a unified strategy for survival in an interconnected, ever-messier, more surprising cybered world and examines the institutional adaptations required of our defense, intelligence, energy, and other critical sectors for national security. Demchak introduces a strategy of \"security resilience\" against surprise attacks for a cybered world that is divided between modern, digitally vulnerable city-states and more dysfunctional global regions. Its key concepts build on theories of international relations, complexity in social-technical systems, and organizational-institutional adaptation. Demchak tests the strategy for reasonableness in history's few examples of states disrupting rather than conquering and being resilient to attacks, including ancient Athens and Sparta, several British colonial wars, and two American limited wars. She applies the strategy to modern political, social, and technical challenges and presents three kinds of institutional adaptation that predicate the success of the security resilience strategy in response. Finally, Demchak discusses implications for the future including new forms of cyber aggression like the Stuxnet worm, the rise of the cyber-command concept, and the competition between the U.S. and China as global cyber leaders. Wars of Disruption and Resilience offers a blueprint for a national cyber-power strategy that is long in time horizon, flexible in target and scale, and practical enough to maintain the security of a digitized nation facing violent cybered conflict.

Algorithm for wireless sensor networks in ginseng field in precision agriculture
In the research on energy-efficient networking methods for precision agriculture, a hot topic is the energy issue of sensing nodes for individual wireless sensor networks. The sensing nodes of the wireless sensor network should be enabled to provide better services with limited energy to support wide-range and multi-scenario acquisition and transmission of three-dimensional crop information. Further, the life cycle of the sensing nodes should be maximized under limited energy. The transmission direction and node power consumption are considered, and the forward and high-energy nodes are selected as the preferred cluster heads or data-forwarding nodes. Taking the cropland cultivation of ginseng as the background, we put forward a particle swarm optimization-based networking algorithm for wireless sensor networks with excellent performance. This algorithm can be used for precision agriculture and achieve optimal equipment configuration in a network under limited energy, while ensuring reliable communication in the network. The node scale is configured as 50 to 300 nodes in the range of 500 × 500 m 2 , and simulated testing is conducted with the LEACH, BCDCP, and ECHERP routing protocols. Compared with the existing LEACH, BCDCP, and ECHERP routing protocols, the proposed networking method can achieve the network lifetime prolongation and mitigate the decreased degree and decreasing trend of the distance between the sensing nodes and center nodes of the sensor network, which results in a longer network life cycle and stronger environment suitability. It is an effective method that improves the sensing node lifetime for a wireless sensor network applied to cropland cultivation of ginseng.

Opportunities and Challenges of Cloud Computing to Improve Health Care Services
Cloud computing is a new way of delivering computing resources and services. Many managers and experts believe that it can improve health care services, benefit health care research, and change the face of health information technology. However, as with any innovation, cloud computing should be rigorously evaluated before its widespread adoption. This paper discusses the concept and its current place in health care, and uses 4 aspects (management, technology, security, and legal) to evaluate the opportunities and challenges of this computing model. Strategic planning that could be used by a health organization to determine its direction, strategy, and resource allocation when it has decided to migrate from traditional to cloud-based health services is also discussed.
