Development tools for mobile devices in market price information systems

There are already several applications on mobile devices that can be useful in agriculture. For example: GPS-enabled map software, individual cattle identification and tracking software and even complex agricultural systems. These are just beginning to spread in the Hungarian agrifood sector. The possibility of using for agribusiness of mobile internet and mobile tools is increasing. Mobile tools are really suitable for tasks like inspecting the evolution of prices of agricultural products. One of our application development is a mobile extension to access the Market Price Information System run by the Hungarian Agricultural Economics Research Institute. The accessibility of information demanded by market actors can be ensured effectively by using mobile tools. The biggest limitation for PDA is screen size. If it is getting smaller from full screen to PDA-sized and yet further to mobile phone dimensions, user performance drops. The main reason for this is that smaller screens make it more difficult for a user to make good judgements about the usefulness of any particular information. The development methods and tools help us to solve one part of these problems

Allo-network drugs: Extension of the allosteric drug concept to protein-protein interaction and signaling networks

Allosteric drugs are usually more specific and have fewer side effects than orthosteric drugs targeting the same protein. Here, we overview the current knowledge on allosteric signal transmission from the network point of view, and show that most intra-protein conformational changes may be dynamically transmitted across protein-protein interaction and signaling networks of the cell. Allo-network drugs influence the pharmacological target protein indirectly using specific inter-protein network pathways. We show that allo-network drugs may have a higher efficiency to change the networks of human cells than those of other organisms, and can be designed to have specific effects on cells in a diseased state. Finally, we summarize possible methods to identify allo-network drug targets and sites, which may develop to a promising new area of systems-based drug design

Comparison of Moodle and ATutor LMSs

E-learning is a technology that plays an important role in modern education and training. Its great importance lies in the fact that it makes learning content readily available at any place at any time. This paper examines and evaluates two of current systems Moodle and ATutor. The main aim of this paper is to identify the aspects of theese LMS systems, examine their functional features, modules, standards, hardware and software requirements, and compare them

Documents about the story of the Hungarian-Libyan diplomatic connections

The aim of this study is to introduce sources that came to existence during the official and non-official negotiations between Hungary and Libya started at the end of the 1950s. In the mirror of these we can get an objective picture about the steps of the Hungarian diplomacy towards the Libyan partner. This work used mainly those diplomatic documents from the National Archives of Hungary that have reference to Libya. Most of the documents are from the State Department and from the embassy of the People's Republic of Hungary in Cairo. Furthermore, some documents are from the Washington, Moscow and Belgrade embassies of the People's Republic of Hungary1

Genetikus algoritmus alkalmazása a mezőgazdasági termelés optimalizálásában

In our paper we try to make a short description about optimization techniques in agricultural production processes. We introduce a new solution in this area, the genetic algorithm (GA), which can solve the optimization problems and can find not only the local but the global solution. There are advantages and disadvantages of GA against traditional algorithms and the conditions and constraints determine which methods are in the best optimization package
