Moving Map and Situational Awareness Capabilities of the DAGR
This paper presents an overview of the Moving Mapp and Situational Awareness capabilities of the Defense Advanced GPS Receiver (DAGR) military handheld GPS receiver (refer to Figure 1), and how these capabilities can be utilized for other applications. The paper first presents an overview of situational awareness and moving maps as provided by handheld GPS receivers, factors driving the DAGR\u27s requirements, and the requirements themselves.
This paper presents the system design in a two-part approach corresponding to the two primary components of the system: 1) importing digital map products into the DAGR and 2) displaying moving maps and situational awareness on the DAGR\u27s display. A significant driver to the design is the requirement to import and display both vector map products and raster map products. The design also needs to allow the use of specialized digital map data, created by the Military\u27s Geospatial Engineers, containing real-time intelligence information and tailored to contain information relevant to a particular mission. The design also provides the ability to import nongeospatial images to allow digital images to be utilized in the field for assistance in identification (e.g. photo of target) or mission operation (e.g. floor plans of a building). The suitability of the ArcMapTM component of the Commercial Joint Mapping Toolkit (C/JMTK) in this design is also presented. This paper concludes with an overview from the user\u27s point of view of the operation of importing digital maps (pre-mission) into the DAGR and using moving map and situational awareness on the DAGR. The overview will also contain a discussion noting some of the possible ways the mapping capabilities can be used by other applications (e.g. adding a survey marker layer to a vector map product) or can be integrated with other systems (e.g. FBCB2/BFT).

The transformation of community hospitals through the transition to value-based care: Lessons from Massachusetts
Enabling community hospitals to provide efficient and effective care and maintain competition on par with their academic medical center (AMC) counterparts remain challenges for most states. Advancing accountable care readiness adds to the complexity of these challenges. Community hospitals experience narrower operating margins and more limited access to large populations than their AMC counterparts, making the shift to value-based care difficult. Massachusetts has taken legislative action to ensure a statewide focus on reducing healthcare costs, which includes a nearly $120-million grant program supporting community hospital and system transformation toward a value-based environment. The Massachusetts Health Policy Commission’s Community Hospital Acceleration, Revitalization and Transformation (CHART) investment program is the state’s largest effort to date aimed at readying community hospitals for value-based care. In doing so, Massachusetts has created the largest state-driven, all-payer (payer-blind) readmission reduction initiative in the country. n this paper, we examine the design and evolution of CHART Phases 1 and 2 and offer insights for other states contemplating innovative approaches to bolstering community hospital participation in value-based care models
Hand Strength Changes Following a Clinical Rotation in Hand Therapy: A Pilot Study
Background: Hand therapy clinical rotations are 12 weeks, and one common anecdotal change frequently expressed is an increase in hand strength. Quantifiable measures of change are not documented in the literature. The purpose of this study is to determine if students experience significant increases in strength during a clinical rotation.
Methods: This study is a quasi-experimental, double-blinded, non-randomized sample of convenience. Grip and pinch strength were assessed pre, mid, and post clinical rotation. Demographic data were collected and reported. Paired t-tests were used to compare means between groups. SPSS 27.0 was used for data analysis.
Results: After removing incomplete data sets, n = 12. Grip strength in the left hand showed a significant increase from pretest to posttest. Grip strength in the right hand showed no difference. Significant increases occurred in both right and left tripod pinch and lateral pinch strength from pretest to posttest. A significant increase was not observed for 2-point pinch strength.
Discussion: This study provides insight into the changes in hand strength in students after a clinical rotation in hand therapy. Significant changes in grip and pinch strength do occur during this time. Increased load in grip and pinch patterns may have clinical implications for therapists practicing long term
Apollo experience report guidance and control systems: Primary guidance, navigation, and control system development
The primary guidance, navigation, and control systems for both the lunar module and the command module are described. Development of the Apollo primary guidance systems is traced from adaptation of the Polaris Mark II system through evolution from Block I to Block II configurations; the discussion includes design concepts used, test and qualification programs performed, and major problems encountered. The major subsystems (inertial, computer, and optical) are covered. Separate sections on the inertial components (gyroscopes and accelerometers) are presented because these components represent a major contribution to the success of the primary guidance, navigation, and control system

Using Electronic Drug Monitor Feedback to Improve Adherence to Antiretroviral Therapy Among HIV-Positive Patients in China
Effective antiretroviral therapy (ART) requires excellent adherence. Little is known about how to improve ART adherence in many HIV/AIDS-affected countries, including China. We therefore assessed an adherence intervention among HIV-positive patients in southwestern China. Eighty subjects were enrolled and monitored for 6 months. Sixty-eight remaining subjects were randomized to intervention/control arms. In months 7–12, intervention subjects were counseled using EDM feedback; controls continued with standard of care. Among randomized subjects, mean adherence and CD4 count were 86.8 vs. 83.8% and 297 vs. 357 cells/μl in intervention vs. control subjects, respectively. At month 12, among 64 subjects who completed the trial, mean adherence had risen significantly among intervention subjects to 96.5% but remained unchanged in controls. Mean CD4 count rose by 90 cells/μl and declined by 9 cells/μl among intervention and control subjects, respectively. EDM feedback as a counseling tool appears promising for management of HIV and other chronic diseases.Boston University and the Office of Health and Nutrition of the United States Agency for International Development (GHS-A-00-03-00030-00); World Health Organization; United States Centers for Disease Control; National Institutes of Health, National Institute of Allergy and Infectious Diseases (K23 AI 62208); Mid-Career Mentoring Award (K24 RR020300
