ABSTRACT Continuous crop expansion has led to a growing demand for phosphate fertilizers. A sound knowledge of the dynamics of phosphorus, and its interaction with iron oxides and organic matter, can be useful to develop effective strategies for sustainable management, especially in a scenario of increasing shortage of mineral phosphate resources. In this paper, we review the relationship of phosphate to iron oxides and organic matter, and its effect on phosphorus availability. Crops typically obtain phosphate from weathered minerals and dissolved fertilizers. However, the amount of phosphorus present in the soil solution depends on the extent to which it is adsorbed or desorbed by iron oxides, which may be influenced by interactions with organic matter. Therefore, systems for fertilizer recomendation based on methodologies considering interactions between soil components such as oxides and organic matter, and the phosphorus sorption capacity resulting from such interactions (e.g. residual P analysis), may be more reliable to ensure efficient, rational use of phosphate.

In more than ten years, quality of electricity has growed from clearness to be an principal issue. One heavy problems from quality of power is harmonic distortion and its consequences. Particularly, the increasing of penetration of loads bases on power electronics (non-linear load) what creates a harmonic distortion in AC power systems. Then, quality of electricity becomes principal issue for utility and its consumer and both swiftly adopts philosophy and proposes limits in new international standard (IEC, EN, BS, IEEE). As consequence the equipments of power conditioning (converter) will become more important for electrical utility and its consumer. From the results with the data logger recording at PT SOSRO distribution feeder system found that there are several current and voltage harmonics are significant in the load and hence the supply side. Fifth and the seventh Harmonic are heaviest harmonic components in the current load. Installation of passive filters will be one solution to overcome the issue with the current harmonics. The recomendation proposed will be submitted to management for consideration PT SOSRO factory in determining which type of passive filter will be used.

This research used the success model of information system from Delone and Mc. Lean which has been modified based on the need and the situation at STKIP Muhammadiyah Pringsewu. The respondents were the first year students in the academic year 2012-2013 and the operators of SIAKAD. The number of the respondents were 196 students and 10 operators. The process of validity and reliability and the hyphotesa used Structural Equation Modeling (SEM). Which is analysed using Amos 20 software.The result of this research showed that from 5 hyphotesis which have been formulated, four of them were received. These hypothesis are the following : the quality of information influence the satisfying of the user ; the quality of the system influence the satisfying of the user; the trust influence the satisfying of the user; and the satisfying of the user influence the benefits of the SIAKAD. On the other hard, the quality of the service doesn’t has significant influence to the satisfying of the SIAKAD user. The success factors, which were resulted in this research, will be used as the suggestion and recomendation in the next SIAKAD development so that the sevice quality of SIAKAD to the students will increase. Keywords: Information Systems Success, DeLone and McLean Model, Structural Equation Modeling (SEM), Analysis of Moment Structures (AMOS).

Android Based Diabetic Manager (ABDM) is an application used for diabetic patients to control their diet. This application is an easy way to remind them in consuming foods and giving them alert when its necessary calories have been achieved. This study was conducted in response to technological developments in the Era 4.0 to help people with Type 2 Diabetes Mellitus through diet control that can be done independently. This study was conducted in the city of Magelang aimed to evaluate whether using ABMD was effective to improve patients adherence in their diet and to control their blood glucose levels. This experimental study was using pre test and post test with control group design. By using simple random sampling, 52 people suffering from Type 2 Diabetes Mellitus recruited in this study devided into two groups, ABDM group and control group. The Pearson Chi-Square test result showed that there was significantly different between ABDM group and control group in the status of blood glucose control and patient adherence with p value was 0.048and 0.000 respectively (p value <0.05). This result indicated that H0 was rejected and H1 was accepted, which could be interpreted that Android based Diabetic Managerapplication influenced the status of blood sugar control and improved the patient adherence in managing their diet. Android based Diabetic Managerapplication influenced the status of blood sugar control and improved the patient adherence in managing their diet. Recomendation was made to conduct future study in the wider Diabetes community by adding more complete types of menu list and its variations in the Android based Diabetic Manager.

The article analyses the good practice of Finland, which reconstructed the path changing towards building innovation-based economy, and Denmark, where the several programmes for network building and enhancement of collaboration between entrepreneurs as well as entrepreneurs and research institutes were introduced successfully, in order to make recomendations for development of economic environment in Latvia. The authors consider, that in the case of Latvia, at first, the government must take action in order to establish the macro-level environment that enables conditions for innovative self-renewing systems as well as introduce schemes that would facilitate knowledge spillover and commercialization, promote business activities of academic staff and researchers, as well as formation of networks and clusters.

The days when only specialists worked with programs and the functionality was the most important have long passed. In today's competitive environment, an important marketing component is reliability in which the only tangible part of the program, the interface, plays a large role. Purely psychological, it is important for the users' visibility, correctness and can even be argued, friendliness. This is determined by the elements of visibility and components' location in intuitively expected places, design integrity, tone and choice of characteristic elements which, together, create a feeling of sympathy or antipathy from the software user. Regularities, which ultimately determine the user's subconscious reactions, are found in natural formations - from the most basic proportions of plants to more sophisticated self-arranged compositions. The harmony of the structures of natural systems, that is, their internal organization, is subject to certain mathematical laws. Objective world stable stationary states corresponding to particular figures, called generalized Golen Ratios. These figures are all the structure of the invariant, which are embodied by the dialectic structure of the world and the different variations that can be observed at every step of nature. It is important to note that with the generalized Golden Ratio, not only is the well-known ratio of 1:1,618 understood, but a whole line of relationships, where like in music, a single major or minor note can be played, and another can stand out from the whole ensemble. The main applications of the Goden Ratio in interface design are space division, caption-font size ratios, restrictive areas (buttons), title queue length, color tone saturation ratio, and cell location coordinates. In this paper, we propose certain recomendations for the development of a user - friendly interface. These recommendations suggest uses in the software developer training process for non-design specialty students; target group - programmers, computer specialists, and IT project managers. The article does not address the development of graphic design tools and their functionality.

The processing of product buying is a very difficult task when we have thousands of items in each market category. In order to study items similarity for dependable buying we try to analyze item descriptions on AliExpress, eBay marketplaces and test k-means algorithm for item grouping/product segmentation. The usage of the classical clusterization algorithms for grouping similar products according to their descriptions is studied. A corpus of different products (bikes and smartphones) from e-shop AliExpress, eBay is developed. Each entity in this corpus contains photos and a product description. Each entity in this corpus contains product description with different fields. These short texts are used for experiments. As a result, it is found out that the k-means algorithm works well only for uniformly distributed data by categories, but this is not suitable for the segmentation of heterogeneous descriptions. The task of item descriptions systematization is set in the research below.

Dissertação de mestrado em Engenharia de Sistemas
O projeto de dissertação aborda a implementação de uma Solução de Business Intelligence e aplicação de algoritmos de recomendação num contexto empresarial. Numa primeira fase foi elaborado o estudo da arte dos principais temas, os Sistemas Business Intelligence e os Sistemas de Recomendação. O levantamento de requisitos foi uma componente do projeto que serviu para definir os objetivos do desenvolvimento e perceber que problemas é que seriam resolvidos com as implementações. A análise da fonte de dados da organização foi também elaborada de forma a assegurar a informação necessária para o cumprimento dos objetivos. A fase de desenvolvimento levou a cabo o desenho de um modelo dimensional para a implementação física de um Data Warehouse. A construção de uma pipeline ETL foi realizada de forma a armazenar os dados com conformação estruturada no Data Warehouse. O Sistema de Data Warehousing ficou completo depois de se programar um job do SQL Server para executar o processo ETL a uma hora estipulada todos os dias, de forma a refrescar os dados contidos na nova base de dados. Foi desenvolvida uma aplicação de monitorização das atualizações do Data Warehouse, de forma a que o gestor das bases de dados possa realizar auditorias e analisar estatísticas dos tempos do processo ETL, apenas acedendo à aplicação na sua versão web ou mobile. Com os dados estruturados e armazenados no Data Warehouse, foi possível desenvolver um algoritmo de recomendações, filtrando desta forma, informações úteis para os utilizadores do sistema, e arrecadando novas oportunidades que são recomendadas por esta componente. Com todo o processo de back-end criado, foi elaborada a fase de front-end. Para ser possível o acesso aos dados contidos no sistema de Business Intelligence, foram criados relatórios dinâmicos numa aplicação web para que os utilizadores consigam analisar as informações, oferecendo-lhes, desta forma, suporte nas tomadas de decisão. Atualmente, o sistema encontra-se em fase de produção, dentro da organização, sendo que é constantemente necessária a sua manutenção para corrigir falhas que possam ocorrer.
This dissertation addresses the implementation of a Business Intelligence Solution and the application of recommendation algorithms in a business context. In the first phase it was elaborated the study of the main themes, Business Intelligence Systems and Recommendation Systems. The requirements gathering was a component of the project that served to define the objectives of the development and to understand which problems would be solved with the implementations. The analysis of the organization's data source was also elaborated in order to ensure the necessary information for the fulfillment of the objectives. The development phase carried out the design of a dimensional model for the physical implementation of a Data Warehouse. An ETL pipeline was built in order to store structured data in the Data Warehouse. The Data Warehousing System was completed after a SQL Server job was scheduled to run the ETL process at a stipulated time every day, in order to refresh the data contained in the new database. A Data Warehouse update monitoring application was developed, so that the database manager can perform audits and analyze statistics of the ETL process times, just by accessing the application in its web or mobile version. With the data structured and stored in the Data Warehouse, it was possible to develop a recommendation algorithm, thus filtering useful information for the system users, and collecting new opportunities that are recommended by this component. With all the back-end process created, the front-end phase was elaborated. To make possible the access to the data contained in the Business Intelligence system, dynamic reports were created in a web application so that the users can analyze the information, offering them, this way, support in the decision-making process. Currently, the system is in the production phase, within the organization, and its maintenance is constantly needed to correct failures that may occur.
