1 INTRODUCTION In spite of the development of the modern technology the sea transport depends largely on the human action. Crews of the cargo and passenger ships' have high responsibility, which requires good health, to perform their duties. A tight ship working environment, limited sleep duration, working time by shifts, difficulties in communicating with colleagues, nostalgia, isolation feeling; they all are considered to be factors of fatigue and stress that can lead to various consequences [1]. In order to prevent human caused accidents and to increase the safety awareness among the crews it is obligatory to measure, control and manage functional status of seafarers in maritime work- environment. The sea transport leaders drew attention to the factors causing fatigue and stress, since only by reducing or eliminating them the safety of navigation could be ensured and more workers attracted. The leaders also pointed out the need to initiate a new crew views toward maritime education and training. Such measures would help to create better working and living environment, increase efficiency, productivity and safety for crew members. Assessment of seafarers’ functional status during marine missions requires tele informatic system, which should be based on the online access [2]. The most modern online database management systems (DBMS) were designed to work in a global network, using Web technologies. Database management systems are multifunctional enabling to store structured data, edit the existing data, and to perform a quick search for the desired criteria. The main feature of such systems is integrity – a possibility to collect data from different users (databanks) and to get access to the database independently from other users. Database management tools not only allow at any time quickly to get complete and accurate information, keep it in compact format, but also provide an opportunity to deal with automated data overload, consistency, integrity and standardization security problems. One of the most widely used types of DBMS – relational model, based on the mathematical theory of relational algebra. The relational model is special because it provides data tables and performs specific operations with these tables. Another important feature of this model - structural independence, i.e., the data can be changed without changing the structure of the software or data processing procedures. Such DBMS becomes available to consumers from virtually any location and requires minimum cost, but gives a lot of comfort, especially when working for many users simultaneously. The data of research are collected from the variety of tests and questionnaires; because of that the central storage of data is more efficient and less costly, especially using them for statistical analysis [3]. This paper concentrates on the development of data bank for seafarers’ functional status assessment. Web-based Databank for Assessment of Seafarers’ Functional Status During Sea Missions G. Varoneckas, A. Martinkenas, J. Andruskiene, A. Stankus, L. Mazrimaite & A. Livens Klaipeda University, Klaipeda, Lithuania ABSTRACT: This paper introduces the basic concept of a new developed web-based databank for an assessment of seafarers’ functional status during the sea missions. The Web system is based on client-server architecture and the international open source technologies including Apache web server, PHP scripts and MySQL database. The paper focuses on the aspects and first results of the initial practical realization of the web-based databank. The main operational advantage of the developed system is the capability to on-line handle up to a dozen users at the same time. The system includes administrative data and questionnaires. Electronic data entry saves the time and material resources.
