    The likely system concepts which might be representative of NASA and DoD space programs in the 1980-2000 time period were studied along with the programs' likely needs for major space transportation vehicles, orbital support vehicles, and technology developments which could be shared by the military and civilian space establishments in that time period. Such needs could then be used by NASA as an input in determining the nature of its long-range development plan. The approach used was to develop a list of possible space system concepts (initiatives) in parallel with a list of needs based on consideration of the likely environments and goals of the future. The two lists thus obtained represented what could be done, regardless of need; and what should be done, regardless of capability, respectively. A set of development program plans for space application concepts was then assembled, matching needs against capabilities, and the requirements of the space concepts for support vehicles, transportation, and technology were extracted. The process was pursued in parallel for likely military and civilian programs, and the common support needs thus identified

    The results are presented of a study which identifies over 100 new and highly capable space systems for the 1980-2000 time period: civilian systems which could bring benefits to large numbers of average citizens in everyday life, much enhance the kinds and levels of public services, increase the economic motivation for industrial investment in space, expand scientific horizons; and, in the military area, systems which could materially alter current concepts of tactical and strategic engagements. The requirements for space transportation, orbital support, and technology for these systems are derived, and those requirements likely to be shared between NASA and the DoD in the time period identified. The high leverage technologies for the time period are identified as very large microwave antennas and optics, high energy power subsystems, high precision and high power lasers, microelectronic circuit complexes and data processors, mosaic solid state sensing devices, and long-life cryogenic refrigerators

    Advanced space system concepts and their orbital support needs (1980 - 2000). Volume 3: Detailed data. Part 1: Catalog of initiatives, functional options, and future environments and goals

    The following areas were discussed in relation to a study of the commonality of space vehicle applications to future national needs: (1) index of initiatives (civilian observation, communication, support), brief illustrated description of each initiative, time periods (from 1980 to 2000+) for implementation of these initiatives; (2) data bank of functional system options, presented in the form of data sheets, one for each of the major functions, with the system option for near-term, midterm, and far-term space projects applicable to each subcategory of functions to be fulfilled; (3) table relating initiatives and desired goals (public service and humanistic, materialistic, scientific and intellectual); and (4) data on size, weight and cost estimations

    It is the problem of this thesis, insofar as possible, to set forth the data necessary in giving one a composite history of the evolution of educational opportunities in Ness County, Kansas. To accomplish this it was necessary to trace the story of the schools, as well as the community, from their very inception in Ness County until the present time. The period to be covered in this study dates back to 1878 when the first schools were established, to the present time

    A Guide for Implementation of the Montessori Theory of Education in the Lower Elementary Program

    In this project, the author categorized the Montessori curriculum into grade levels so that parents will know what the expectations will be for the average student by the end of 1st, 2nd, or 3rd grade. The Montessori materials are divided into subjects across the curriculum. The scope and sequence was developed by a research of various Montessori schools and training centers. These schools were classified as private, public, or charter; some had an affiliation with AMI or AMS. The information received was checked and cross-referenced, comparing the information from one school with another. Next, a model was established which became the content of the curriculum guide. The information contained within the guide is not based upon one’s opinion, but upon the facts received
