The thesis is focused on the study and optimize inventory management at Kordárna Plus, a. s. The theoretical part describes the characteristics of the basic concepts related to inventory management, classification, costs associated there with and methods of inventory control. The practical part is focused on the analysis of stocks on the process of procuring, warehousing and inventory control. This analysis uncovered deficiencies for which they proposed solutions. Proposals should lead to improved inventory management in the company.

Thesis (MSc)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: A review of the literature shows the Beck-Depression Inventory (BOl), and its revisions, to have received world-wide support over the past four decades as a screening instrument for depression, proving to be robust amongst various populations and in various translations. Although popular amongst health care practitioners in South Africa, the BOl and its revisions are, however, currently unstandardised amongst South African populations. This current research culminates in the development of a Xhosa translation of the latest revision of the BOl, the BOl-II that accurately reflects the contents of the BOlli, the BOl-Il-X. It is regarded as linguistically and grammatically robust enough to be easily understood by a broad spectrum of Xhosa respondents. The development of the BDI-II-X is discussed, and suggestions regarding future research are given. / AFRIKAANSE OPSOMMING: 'n Oorsig van die literatuur dui aan dat die Beck Depression Inventory (BOl), en sy hersienings, oor die afgelope vier dekades wêreldwye erkenning ontvang het as 'n meetinstrument vir die identifisering van depressie, onder verskeie populasies en in verskeie vertalings. Alhoewel dit populêr onder gesondheidspraktisyne in Suid-Afrika is, bly die BOl, en sy hersienings, huidiglik ongestandardiseerd onder Suid-Afrikaanse populasies. Die navorsing wat aangebied word, word saamgevat in die ontwikkelling van 'n Xhosa vertaling van die nuutste hersiening van die BOl, die BOl-II, wat die inhoud van die BOl-II akkuraat reflekteer, die BOl-li-X. Taalkundig word die BOI-II-X beskou as 'n vertaling wat maklik onder 'n breë spektrum van die Xhosa populasie verstaanbaar is. Die ontwikkelling van die BOI-II-X word bespreek, en aanbevelings rakende toekomstige navorsing word aangebied.

<p>Högskolestudenters upplevda livskvalitet har varit ett eftersatt forskningsområde. Syftet med denna studie var att undersöka hur studenter på grund- respektive forskarutbildningen vid Stockholms universitet upplevde sin livskvalitet och jämföra resultaten med tidigare insamlade data från en normalgrupp. För att mäta den upplevda livskvaliteten användes formuläret Quality of life inventory, QOLI. Totalt inkom 1300 enkäter från studenter på grundutbildningen och 115 enkäter från studenter på forskarutbildningen. Resultaten visar att både studenter på grund- respektive forskarutbildningen skattar sin upplevda livskvalitet som signifikant lägre än normalgruppen. Vidare framkom att kvinnor skattar sin livskvalitet som högre än män och att gifta och samboende skattar sin livskvalitet som högre än ogifta. Resultaten överrensstämmer med den forskning som tidigare genomförts för högskolestudenters subjektivt upplevda livskvalitet.</p>

This study tested whether an American Sign Language (ASL) MMPI short form, the Brauer-Gallaudet MMPI-168 (B-G MMPI-168), could discriminate between groups of deaf adults with and without psychopathology. B-G MMPI-168 and MMPI-168 profiles were also compared in deaf adults without a history of psychopathology. Independent variables were history of mental health treatment, language of administration and reading ability. Dependent variables were MMPI-168 and B-G MMPI-168 validity and clinical scale evaluations. Fifty-nine deaf adults from the community and outpatient counseling services completed demographic information on a questionnaire developed especially for this study. Subjects were divided into Clinic and Control groups based on history (Clinic) or no history (Control) of mental health treatment. Reading Comprehension scores (Advanced Stanford Achievement Test) of Control subjects determined placement in Control (I), (11th grade and above) and Control (II), (6-11 grade) groups. All subjects took the B-G MMPI-168. Control subjects took the MMPI-168 at home within two weeks. Ten dollars was earned for participation. Results indicated that Clinic and Control (II) groups were not accurately discriminated by B-G MMPI-168 profiles. The "hit rate" for the Clinic group was 96.5 percent, but only 40.0% of the Control subjects were correctly classified as Not Disturbed. This version of the B-G MMPI-168 was judged unacceptable for clinical use until items are revised. Level of reading ability was not a significant factor in the clinical validity of the MMPI-168. The "hit rates" of correct classification of Control (I) and Control (II) subjects as Not Disturbed, 58.8 and 46.2, respectively, were unacceptable. Language of administration was not a significant factor in the clinical validity of Control group "168" profiles. B-G MMPI-168 profiles showed more psychopathology than MMPI-168 profiles, but both tests had unacceptably high percentages of Control subjects classified as Disturbed. Revision of B-G MMPI-168 items was recommended so that profiles can accurately discriminate between Clinic and Control groups. The MMPI-168 was recommended for use as part of a personality assessment battery for deaf adults having 12th grade equivalent or higher reading level.

In today’s global and competitive markets selling products at competitive prices, coordination of supply chain configuration, and environmental and ecological consciousness and responsibility become important issues for all companies around the world. The price of products is affected by costs, one of which is inventory cost. Inventory does not give any added value to products but must be kept in order to fulfill the customer demand in time. Therefore, this cost must be kept at the minimum level. In order to reduce the amount of inventory across a supply chain, coordination of decisions among all players in the chain is necessary. Coordination is needed not only for a two-level supply chain involving a manufacturer and its customers, but also for a complex supply chain of multiple tiers involving many players. With increasing attention being placed to environmental and ecological consciousness and responsibility, companies are keen to have a reverse supply chain where used products are collected and usable components remanufactured and reused in production to minimize negative impacts on the environment, adding further complexity to decision making across a supply chain. To deal with the above issues, this thesis proposes and develops the mathematical models and solution methods for coordinating the production inventory system in a complex manufacturing supply chain involving reverse logistics and multiple products. The supply chain consists of tier-2 suppliers for raw materials, tier-1 suppliers for parts, a manufacturer who manufactures and assembles parts into finished products, distributors, retailers and a third party who collects the used products and returns usable parts to the system. The models consider a limited contract period among all players, capacity constraints in transportation units and stochastic demand. The solution methods for solving the models are proposed based on decentralized, semi-centralized and centralized decision making processes. Numerical examples are used by adopting data from the literature to demonstrate, test, analyse and discuss the models. The results show that centralised decision making process is the best way to coordinate all players in the supply chain which minimise total cost of the supply chain as a whole. The results also show that the selection of the length of limited horizon/ contract period will be one of the main factors which will determine the type of coordination (decentralised, centralised or semi-centralised) among all players in the supply chain. We also found that the models developed can be viewed as generalised models for multi-level supply chain by examining the models using systems of different tiers from the literature. We conclude that the models are insensitive to changes of input parameters since percentage changes of the supply chain’s total cost are less than percentage changes of input parameters for the scenarios studied.

The problem with which this investigation was concerned was that of determining the extent various subgroups of individuals within certain clinical groups would agree in terms of how to rank order Maslow's basic needs.
