Supistamista, rationalisointia vai kehittämistä? : Valtiovarainministeriön järjestelyosaston järjestämän henkilöstökoulutus- ja tutkimustoiminnan rakentuminen osaksi valtionhallintoa vuosina 1943-1971

The study examines the personnel training and research activities carried out by the Organization and Methods Division of the Ministry of Finance and their becoming a part and parcel of the state administration in 1943-1971. The study is a combination of institutional and ideological historical research in recent history on adult education, using a constructionist approach. Material salient to the study comes from the files of the Organization and Methods Division in the National Archives, parliamentary documents, committee reports, and the magazines. The concentrated training and research activities arranged by the Organization and Methods Division, became a part and parcel of the state administration in the midst of controversial challenges and opportunities. They served to solve social problems which beset the state administration as well as contextual challenges besetting rationalization measures, and organizational challenges. The activities were also affected by a dependence on decision-makers, administrative units, and civil servants organizations, by different views on rationalization and the holistic nature of reforms, as well as by the formal theories that served as resources. It chose long-term projects which extended to the political decision-makers and administrative units turf, and which were intended to reform the structures of the state administration and to rationalize the practices of the administrative units. The crucial questions emerged in opposite pairs (a constitutional state vs. the ideology of an administratively governed state, a system of national boards vs. a system of government through ministries, efficiency of work vs. pleasantness of work, centralized vs. decentralized rationalization activities) which were not solvable problems but impossible questions with no ultimate answers. The aim and intent of the rationalization of the state administration (the reform of the central, provincial, and local governments) was to facilitate integrated management and to render a greater amount of work by approaching management procedures scientifically and by clarifying administrative instances and their respon-sibilities in regards to each other. The means resorted to were organizational studies and committee work. In the rationalization of office work and finance control, the idea was to effect savings in administrative costs and to pare down those costs as well as to rationalize and heighten those functions by developing the institution of work study practitioners in order to coordinate employer and employee relationships and benefits (the training of work study practitioners, work study, and a two-tier work study practitioner organization). A major part of the training meant teaching and implementing leadership skills in practice, which, in turn, meant that the learning environment was the genuine work community and efforts to change it. In office rationalization, the solution to regulate the relations between the employer and the employees was the co-existence of the technical and biological rationalization and the human resource administration and the accounting and planning systems at the turn of the 1960s and 1970s. The former were based on the school of scientific management and human relations, the latter on system thinking, which was a combination of the former two. In the rationalization of the state administration, efforts were made to find solutions to stabilize management ideologies and to arrange the relationships of administrative systems in administrative science - among other things, in the Hoover Committee and the Simon decision making theory, and, in the 1960s, in system thinking. Despite the development-related vocabulary, the practical work was advanced rationalization. It was said that the practical activities of both the state administration and the administrative units depended on professional managers who saw to production results and human relations. The pedagogic experts hired to develop training came up with a training system, based on the training-technological model where the training was made a function of its own. The State Training Center was established and the training office of the Organization and Methods Division became the leader and coordinator of personnel training.

Optical properties of the organic substances from aqueous humus surface waters. [Translation from: Gidrochim. Mat. 23, 31-35, 1955]

Dissolved organic matter, especially turf and peat, is repsonsible for the colouration of water. The reported study tried to determine the nature of the colouring agent or organic matter by the establishment of a relationship between the intensity of colouration and the total organic matter content. 44 waters from different sources were examined.

"Mamíferos de médio e grande porte na Floresta Nacional de Carajás, Pará: riqueza, abundância e efeitos da fitofisionomia e do impacto da mineração"

A Floresta Nacional de Carajás é uma unidade de conservação federal localizada no sudeste da Amazônia, região Norte do Brasil. Juntamente com outras cinco áreas formam o Mosaico de Carajás com um contínuo de 1.307.000 hectares de área protegida. As principais fitofisionomias presentes no interior da unidade são a Floresta Ombrófila Densa e a Savana Metalófila. A unidade abriga a maior província mineral do mundo. A atividade de mineração promove diferentes impactos sobre a fauna principalmente através da modificação de paisagem originada pela supressão vegetal. O objetivo desse trabalho foi estudar a composição da comunidade de mamíferos de médio e grande porte através do levantamento de informações sobre a riqueza, a abundância e as diferenças entre a composição da mastofauna nas fitofisionomias de Savana Metalófila e Floresta Ombrófila Densa e suas alterações ocasionadas pelo impacto da mineração. Foram realizadas quatro campanhas em 19 trilhas que se distribuíram em áreas de Savana Metalófila e Floresta Ombrófila Densa impactadas e controle. A metodologia utilizada foi de transecção linear e armadilhamento fotográfico com um esforço total empregado de 432 km e 85.920 horas, para cada um dos métodos, respectivamente. A comunidade de mastofauna de médio e grande porte apresentou 43 espécies distribuídas em oito ordens, com um aumento de 41% de novos registros para a região. A composição da comunidade de mastofauna apresentou diferenças quanto a riqueza e a abundância das espécies nas duas fitofisionomias e quanto ao efeito do impacto da mineração. O presente trabalho trouxe avanços em relação à lista de espécies de mamíferos de médio e grande porte e aumentou o conhecimento a respeito da composição desta fauna em ambientes de floresta e de savana na Floresta Nacional de Carajás. Trouxe informações acerca dos impactos sobre a mastofauna e identificou importantes sensibilidades de algumas espécies frente à mineração, contribuindo para a busca do equilíbrio entre a mineração e a conservação.

HEAVY VEHICLE VIBRATION - A CASE STUDY.

A method is presented for the digital simulation of multiple degrees-of-freedom lumped parameter vibrating systems with arbitrary constitutive elements in an inertial frame of reference. The geometry of the system is treated independently of the constitutive elements and as a result nonlinear (time domain) or linearised (frequency domain) calculations may be performed using a single input description. The method is used to simulate a 3-axle rigid heavy commercial vehicle for harsh vibrating conditions. Some of the assumptions to which the calculations are sensitive are examined. Agreement between the response of a 3-dimensional whole vehicle model and measurements on the test vehicle is satisfactory.

Imbibition dynamics of nano-particulate ink-jet drops on micro-porous media

Ink-jet printing of nano-metallic colloidal fluids on to porous media such as coated papers has become a viable method to produce conductive tracks for low-cost, disposable printed electronic devices. However, the formation of well-defined and functional tracks on an absorbing surface is controlled by the drop imbibition dynamics in addition to the well-studied post-impact drop spreading behavior. This study represents the first investigation of the real-time imbibition of ink-jet deposited nano-Cu colloid drops on to coated paper substrates. In addition, the same ink was deposited on to a non-porous polymer surface as a control substrate. By using high-speed video imaging to capture the deposition of ink-jet drops, the time-scales of drop spreading and imbibition were quantified and compared with model predictions. The influences of the coating pore size on the bulk absorption rate and nano-Cu particle distribution have also been studied.

Preparation of silver nanowires in ion-track membranes

Polycarbonate (PC) membranes were irradiated with swift heavy ions and latent tracks were created along the ions' trajectories. Nanopores, diameters between 100 and 500 nm, were obtained after illuminating the membranes with UV light and etching in NaOH solution. Silver nanowires were produced in the etched ion-track membranes by electrochemical deposition. The morphology and crystallinity of the silver nanowires were studied by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and selected area electron diffraction (SAED). Under certain conditions (deposition voltage 25 mV, current density 1-2 mA.cm(-2), temperature 50 degrees C, electrolyte 0.1 mol.L-1 AgNO3), single-crystalline silver nanowires with preferred orientation along the [111] direction can be synthesized.

A Self-initializing Eyebrow Tracker for Binary Switch Emulation

We designed the Eyebrow-Clicker, a camera-based human computer interface system that implements a new form of binary switch. When the user raises his or her eyebrows, the binary switch is activated and a selection command is issued. The Eyebrow-Clicker thus replaces the "click" functionality of a mouse. The system initializes itself by detecting the user's eyes and eyebrows, tracks these features at frame rate, and recovers in the event of errors. The initialization uses the natural blinking of the human eye to select suitable templates for tracking. Once execution has begun, a user therefore never has to restart the program or even touch the computer. In our experiments with human-computer interaction software, the system successfully determined 93% of the time when a user raised his eyebrows.

WIMU instrumentation of assassin trainer & skeleton sled

Skeleton is a high‐speed Winter Olympic sport performed on the same twisting, downhill ice tracks used for Bobsleigh & Luge. The single rider sprints and pushes their sled for 20‐30m on a level start section before loading and going through a twisting course of over 1km, at speeds up to 140km/h, experiencing up to 5g. In competition, the top athletes can be within a fraction of a second of each other. The initial short pushing period is believed to be critical to overall performance but it is not well understood. A collaborative project between University of Bath, UK Sport and Tyndall National Institute is instrumenting skeleton athletes, training equipment and test tracks with Tyndall’s Wireless Inertial Measurement Unit technology in order to investigate and improve understanding of this phase of a skeleton run. It is hoped this will lead to improved training regimes and better performance of such elite, Olympic level athletes. This work presents an initial look at the system as implemented and data recorded.

A model to predict the life of pneumatic conveyor bends

A new approach to the prediction of bend lifetime in pneumatic conveyors, subject to erosive wear is described. Mathematical modelling is exploited. Commercial Computational Fluid Dynamics (CFD) software is used for the prediction of air flow and particle tracks, and custom code for the modelling of bend erosion and lifetime prediction. The custom code uses a toroidal geometry, and employs a range of empirical data rather than trying to fit classical erosion models to a particular circumstance. The data used was obtained relatively quickly and easily from a gas-blast erosion tester. A full-scale pneumatic conveying rig was used to validate a sample of the bend lifetime predictions, and the results suggest accuracy of within ±65%, using calibration methods. Finally, the work is distilled into user-friendly interactive software that will make erosion lifetime predictions for a wide range of bends under varying conveying conditions. This could be a valuable tool for the pneumatic conveyor design or maintenance engineer.
