The purpose of this paper is to report on a study involving the specification (using Unified Modelling Language (UML) 2.0) of information requirements and implementation of the software components for generating catalogue cards. The implementation in a Java environment is developed using the FreeMarker software.

Object‐oriented methodology as well as CASE tools are used to design the software components. The system architecture makes the catalogue cards available from every segment of the library management system, and enables catalogue card updates without recompilation of the source code.

The outcome of the work is a software package, implemented in a Java environment, that generates and displays catalogue cards based on bibliographic records in the UNIMARC format, but it can be easily adapted for the other MARC formats.

The package is limited to generating only catalogue cards based on MARC formats. In order to avoid this limitation it is possible to define specific metadata for catalogue card generation. In such a case, the catalogue cards could be generated from the metadata regardless of the bibliographic record format.

The software package is integrated into the BISIS library management software system used by 36 libraries including public, city, faculty and special libraries in Serbia.

The architecture of the software component can be used in different implementations of library management systems. It is only necessary to represent the bibliographic record data using the internal data structure of the FreeMarker software package.

The purpose of this paper is to examine the use of fused deposition modelling (FDM) models and finite element analysis (FEA) related to dysplastic hip orthopaedic surgery.

The study involved the use of Mimics and Abaqus softwares. Mimics was used to process the CT scan patient data to STL format before producing FDM models which were for before and after surgery. FEA was done to study the two different type of implant biomaterials used in dysplastic hip surgery.

The use of FDM pre models for preplanning of dysplastic hip surgery by orthopaedic surgeons and viewing of the surgery outcome via FDM post models. Different implant biomaterials used gave different results in reduction of stresses that were achieved.

This is original work involving patients in hospital, which got ethical approval and was funded by a university grant. The paper describes a new kind of research in the university.
