Abstract: ENGLISH ABSTRACT: For more than a decade, the South African National Department of Health (DoH) has recognised the potential benefit of information and communication technology (ICT) in the delivery of health care to rural areas. Despite generous funding and proven technology, not many telemedicine systems have proved sustainable after the pilot phase. The purpose of this paper is to develop a maturity model that can be implemented to measure and manage the capability of a health system, for use in the delivery of sustainable health care after the pilot phase of a telemedicine project. The validity of the telemedicine maturity model (TMMM) is tested within the context of the South African public health sector. AFRIKAANSE OPSOMMING: Die Suid Afrikaanse Nasionale Departement van Gesondheid het reeds meer as ’n dekade gelede die voordeel besef wat inligtings- en kommunikasietegnologie kan bied ten opsigte van die lewering van gesondheidsorg in afgele gebiede. Ten spyte van ruim befondsing en bewese tegnologie, is daar egter min volgehoue telegeneeskundedienste in die publieke gesondheidstelsel van Suid Afrika. Die doel van hierdie artikel is om ’n volwassenheids-model te ontwikkel wat gebruik kan word om die vermo van ’n gesondheidstelsel te bepaal en bestuur, ten einde telegeneeskunde loodsprojekte vol te hou. Die geldigheid van hierdie telegeneeskunde volwassenheidsmodel (TMMM) is getoets binne konteks van die publieke gesondheidsektor van Suid Afrika.

Abstract: ENGLISH ABSTRACT: Simulation modelling has been identified as one of the most powerful techniques available for the analysis and design of complex manufacturing systems. A number of manufacturing simulators have been designed in an effort to make it easier to use the simulation approach in the manufacturing environment. This paper will attempt to describe and ~valuate the characteristics of some of the available manufacturing simulators as well as possible ways to alleviate some of the inherent disadvantages. This paper will also report on the preliminary design philosophy and specifications of a manufacturing simulation program generator (FACSIM) presently under development. AFRIKAANSE OPSOMMING: Simulasiemodellering is een van die mees kragtige tegnieke beskikbaar vir die analise en ontwerp van komplekse vervaardigingstelsels. In 'n poging om die gebruik van simulasiemodellering in die vervaardigingsomgewing te vergemaklik is 'n aantal vervaardigingsimulators ontwikkel. Hierdie artjkel sal poog om die eienskappe van sommige van die beskikbare vervaard~gingsimulators te bespreek en te evalueer. Tegnieke wat moontlik gebruik kan word om die effekte van die inherente nadele van simulators te verminder sal bespreek J?, word. Die voorlopige ontwerpfilosofie en -spesifikasie van 'n vervaardigingsimulasie programgenerator (FACSIM), wat tans ontwikkel word, sal ook beskryf word.

Abstract: ENGLISH ABSTRACT: Simulation modelling is a general purpose tool that may be used to provide decision support in a number of application areas. It may be used to analyze, design or "optimize" manufacturing, materials handling, management, commercial and a wide variety of other systems. This paper will report on the design of a prototype decision support tool, based on a simulation model of a vehicle fleet availability problem. The primary purpose of the model is to serve as a tool for the evaluation of the availability of equipment under different conditions and to perform sensitivity analysis. AFRIKAANSE OPSOMMING: Simulasiemodellering is 'n algemeendoelige tegniek wat gebruik kan word vir die verskaffing van besluitsteun in 'n aantal toepassingsgebiede. Dit mag gebruik word vir die analise, ontwerp of "optimisering" van vervaardiging-, materiaalhantering-, bestuur-, kommersieIe en 'n wye verskeidenheid ander stelsels. Hierdie referaat doen verslag oor die ontwikkeling van 'n prototipe besluitnemingshulpmiddel wat gebaseer is op 'n simulasiemodel van 'n voertuigvloot beskikbaarheidsprobleem. Die hoofdoelwit van die model is om te dien as 'n hulpmiddel by die evaluasie van die beskikbaarheid van toerusting onder verskillende omstandighede asook vir die uitvoer van sensitiwiteitsanalise.

Abstract: ENGLISH ABSTRACT: Industrial engineering (IE) is a multi-disciplinary field, with its research borders broadening into a wide range of sub-disciplines. The South African Journal of Industrial Engineering (SAJIE) has been the official voice of IE research in South Africa for the past 22 years. In the interests of evaluating research scope, it is worth determining how IE fields have been covered by this journal. What are the current topics in IE, and how do they align with IE publication trends in other countries? This article attempts to investigate these issues in an objective way by using a text analytical technique to analyse the SAJIE publication collection. Due to the growth in the quantity of accessible textual information, and the growing importance of this type of information to business people and industrial engineers alike, the relevant text analytical method is also outlined. AFRIKAANSE OPSOMMING: Bedryfsingenieurswese is ’n multidissiplinêre veld, met navorsingsgrense wat strek oor ’n wye reeks sub-dissiplines. Die Suid-Afrikaanse Tydskrif vir Bedryfsingenieurswese (SAJIE) was oor die afgelope 22 jaar die amptelike mondstuk vir bedryfsingenieurswese-gerigte navorsing in Suid-Afrika. Dit is betekenisvol om te bepaal in watter hoedanigheid bedryfsingenieurswesevelde deur die SAJIE gedek word, ten einde die bestek van navorsing te evalueer. Wat is die huidige temas van bedryfsingenieurswese, en hoe vergelyk dit met bedryfsingenieurswese-publikasieneigings in ander lande? Hierdie artikel poog om die vraagstuk op ’n objektiewe wyse na te vors deur die toepassing van ’n teksanalitiese tegniek om die SAJIE publikasie versameling te ontleed. Weens die toename in die hoeveelheid beskikbare tekstuele inligting, asook die toenemende belang van hierdie tipe inligting vir besigheidspersone asook bedryfsingenieurs, word die betrokke teksanalitiese metode ook bespreek.

Torres, C.S;Shaeffer, L.;
Matéria (Rio de Janeiro) , 2010, DOI: 10.1590/S1517-70762010000100011
Abstract: the purpose of this work is to analyze the effect of high energy milling on the morphology, particle size and compressibility of wc-ni composite. the hard metal is a composite material used in several areas of machining, mining and construction and can be applied directly to components of drilling equipment for oil and gas. the milling of hard metal wc-20ni, from the wc and ni powders, was performed for milling times of 1, 2, 4, 8, 16, 32 and 64 hours. scanning electron microscopy and laser granulometry were used to follow the influence of milling time on the microstructure. this evaluation allowed to observe the morphological behavior and interaction between the components of the material produced. the results show that the milling time produces a reduction of particle size followed by particle agglomeration with sizes smaller than the components used in the preparation of composites.

Quaternary evolution of the Caravelas strandplain - Southern Bahia State - Brazil
Andrade, Ana C.S.;Dominguez, José M.L.;Martin, Louis;Bittencourt, Abílio C.S.P.;
Anais da Academia Brasileira de Ciências , 2003, DOI: 10.1590/S0001-37652003000300008
Abstract: an evolutionary model is proposed for the caravelas strandplain. the model encompasses integration of: (i) mapping of quaternary deposits, (ii) cartography of beach-ridge alignments and their truncations, (iii) relative sea-level history, (iv) development history of the abrolhos coral reefs, (v) vibra-coring and (vi) c14 dating of quaternary deposits. seven major evolutionary stages were identified. these stages show that the strandplain has had its quaternary evolution strongly controlled by relative sea-level changes. in addition, the development of the abrolhos coral reefs has also played an important role in dispersion and accumulation of sediments along the coastline, causing localized inversion in longshore sediment transport.
