El trabajo de investigación se enfocó en rediseñar la gestión de inventarios en una Estación de Servicios. El análisis reveló que la empresa pierde un monto de 74 336,88 soles, los cuales son originados rincipalmente por la falta de capacitación al personal de la empresa, dispensadores en mal estado, falta de instrumentos de medición precisos para medir inventarios y la falta de un sistema de gestión de inventarios. Para abordar estos desafíos, se propuso la implementación de un modelo de gestión de inventarios basado en el cálculo de inventarios de seguridad, puntos de reorden, junto con mejoras en los procesos logísticos, capacitación del personal y la adquisición de un sistema de medición por telemetría. La evaluación económica respaldó la viabilidad de estas mejoras, al mostrar un Valor Actual Neto (VAN) a 5 años de 64 278,89 soles, una Tasa Interna de Retorno (TIR) del 111,3%, un Beneficio Costo de 1,65 soles y un período de recuperación de 255 días. En resumen, esta investigación identificó desafíos, ofreció soluciones efectivas y generó resultados positivos en la gestión de inventarios que tuvieron un impacto directo en la disminución de las ventas no percibidas. / The research work focused on redesigning inventory management in a Service Station. The analysis revealed that the company loses an amount of 74 336,88 soles, which are mainly caused by the lack of training for the company's personnel, dispensers in poor condition, lack of precise measuring instruments to measure inventories and the lack of an inventory management system. To address these challenges, the implementation of an inventory management model based on the calculation of safety inventories, reorder points, along with improvements in logistics processes, staff training and the acquisition of a telemetry measurement system was proposed. The economic evaluation supported the viability of these improvements, showing a 5-year Net Present Value (NPV) of 64 278,89 soles, an Internal Rate of Return (IRR) of 111,3%, a Cost Benefit of 1,65 soles and a recovery period of 255 days. In summary, this research identified challenges, offered effective solutions, and generated positive inventory management results that had a direct impact on decreasing lost sales.

The majority of adolescents diagnosed with Major Depressive Disorder (MDD) and admitted to a psychiatric hospital in Gauteng complained of being tired of 1'talk therapy" . This study used imagery as a technique in the treatment of two adolescents suffering from MDD. The initial identification was based on the results of the Beck Depression Inventory (BDI). After a number of sessions of implementing imagery techniques, the BDI was readministered. To determine the long-term effectiveness of imagery, the BDI was again administered a month-and-a-half after completion of the sessions. The results before and after indicate a reduction in the severity of depression. The results at the month-and-a-half follow-up session indicated a further reduction in the level of depression in both cases. This indicates the long-tenn effectiveness of imagery in treating depression. Further research is required, but there are significant indications that imagery may be an effective technique in the treatment of depressed adolescents under psychiatric supervision. / Educational studies / M.Ed (Guidance and Counseling)

Thesis (MA (Psychology))--University of Stellenbosch, 2006. / Within the medical models, postpartum depression is constructed as a mental illness, that women are predisposed to during the postpartum period because of the biological and physiological changes that occur before, during and after childbirth. The present study aimed to determine whether childbirth increases the risk of developing depressive symptomatology in the first six months after delivery. The objective of the study was to examine the concept of postpartum depression by analyzing the difference in depressive symptom rates between 41 postpartum women and 254 male and female (who had not given birth in the previous six months) community members residing in a semi-rural area of South Africa. This objective was reached by using a cross-sectional survey research design. The Beck Depression Inventory (BDI) was used to elicit the quantitative data. Several independent t-tests were conducted to determine the following (i) whether low-income women three months postpartum had higher BDI scores in comparison to a combined gendered community sample, and (ii) whether low-income women six months postpartum had higher BDI scores in comparison to a combined gendered community sample. The results indicated that the postpartum women did not experience elevated rates of depressive symptoms at three months or at six months in comparison to the community sample. Men in the 2003 community sample displayed significantly higher levels of depressive symptoms than the sixmonth postpartum women. These findings do not support the assumption that childbirth predisposes women to psychological vulnerability during the postpartum period.

SCA Östrand implements an expansion of its current production of pulp. Today's 435 000 tonnes will be 900 000 tonnes when the new production line is put into operation in 2018. SCA Logistics, which is responsible for the storage and transportation of pulp would therefore like to know how much area that is currently storing pulp and if the existing surface is sufficient to cope with the increase in volume from SCA Östrand. If the surface is not enough, SCA Logistics want to know how much space will be needed to cope with the increase in volume. The study is a combined case study and design methodology. Through process mapping, various scenarios are being developed to implement the current status and future analysis where the purpose of the study can be determined by calculating the maximum area, volume and fill rate. Information has been obtained from printed literature, scientific papers, previous theses, and observations of the process in SCA Logistics in the port of Tunadal. Relevant data has been obtained from an external supervisor at SCA Logistics. The study provides answers to how much space is available at present time, the fact that the current surface will not be sufficient to cope with the increase in volume and a minimum of additional 5800 m2 surface area will be needed to store pulp on. / SCA Östrand genomför i dagsläget en expansion av dess nuvarande produktion av pappersmassa. Dagens 435 000 ton kommer dubbleras när den nya produktionslinjen tas i bruk 2018. SCA Logistics som ansvarar för lagring och transportering av pappersmassan vill således veta hur mycket yta som finns i nuläget att lagra pappersmassa på och om den befintliga ytan är tillräcklig för att klara av volymökningen från SCA Östrand. Om ytan inte räcker till, vill SCA Logistics veta hur mycket yta som kommer behövas för att klara av volymökningen. Studien är en kombinerad fallstudie och designmetodik. Genom en processkartläggning kommer olika scenarion tas fram för att genomföra en nuläges-och framtidsanalys där syftet med studien kommer bestäm-mas genom att beräkna maximal area, volym och fyllnadsgrad. Inform-ation införskaffas från tryckt litteratur, vetenskapliga artiklar, tidigare examensarbeten, samt processpromenader på SCA Logistics i Tunadals-hamnen. Relevant data erhålls från extern handledare på SCA Logistics. Studien ger svar på hur mycket yta som finns tillgängligt i nuläget, att denna yta inte kommer vara tillräcklig för att klara av volymökningen och ett minimum av ytterligare 5800 m2 behövs utöver den nuvarande ytan som finns tillgänglig.

Since the introduction of sustainable development, industries have witnessed significant sustainability challenges. Literature shows that the food industry is concerned about its need for efficient and effective management practices in dealing with perishability and the requirements for conditioned storage and transport of food products that effect the environment. Hence, the environmental part of sustainability demonstrates its significance in this industrial sector. Despite this, there has been little research into environmentally sustainable inventory management of deteriorating items. This thesis presents mathematical modelling based research for production inventory systems in perishable food supply chains. In this study, multi-objective mixed-integer linear programming models are developed to determine economically and environmentally optimal production and inventory decisions for a two-echelon supply chain. The supply chain consists of single sourcing suppliers for raw materials and a producer who operates under a make-to-stock or make-to-order strategy. The demand facing the producer is non-stationary stochastic in nature and has requirements in terms of service level and the remaining shelf life of the marketed products. Using data from the literature, numerical examples are given in order to test and analyse these models. The computational experiments show that operational adjustments in cases where emission and cost parameters were not strongly correlated with supply chain collaboration (where suppliers and a producer operate under centralised control), emissions are effectively reduced without a significant increase in cost. The findings show that assigning a high disposal cost, limit or high weight of importance to perished goods leads to appropriate reduction of expected waste in the supply chain with no major cost increase. The research has made contributions to the literature on sustainable production and inventory management; providing formal models that can be used as an aid to understanding and as a tool for planning and improving sustainable production and inventory control in supply chains involving deteriorating items, in particular with perishable food supply chains.

This thesis deals with control of stock in an inventory, focusing on inventory placement. The purpose of this thesis is to reduce the transport distance within the main stock house while gathering inventory. This will be achieved by reconstructing the inventory placement in consideration with how frequently the inventories get picked and mass of the inventory. In particular, the literature and the data that is collected from the company´s business system have laid the foundation for the thesis. In general, interviews and observations also contributed to the data collection. To fulfill the aim and to produce arbitrary results, two issues have been developed regarding which attributes that should determine the position of the inventory in the stock house and how to obtain a more effective inventory structure? The authors have jointly produced a result of suggestions for future inventory placement in terms of picking frequency and weight. Initially a situation analysis was conducted to identify known problems with the inventory´s placement and storage systems. The problems that were identified were that the inventory placement has no consideration regarding picking frequency. To determine the most frequent picked inventory an ABC analysis was conducted. All of the inventories were spread out throughout the whole stock house. To take in account, the additional criterion, which was weight, a multi-criteria analysis was performed in combination with the ABC analysis. The results of the combined analysis provided that the basis for drawing up concepts for future inventory placement. The proposal includes optimized inventory placements in different zones of the most frequently picked inventory with weight as an additional criterion. / Arbetet behandlar området lagerstyrning med inriktning på optimering av artikelplacering. Syftet med arbetet är att minska transportsträckor inom centrallagret, detta genom en omstrukturerad artikelplacering med hänsyn till plockfrekvens och tyngd. I synnerhet har litteratur samt insamlad data från företagets affärssystem lagt grunden för arbetet. I allmänhet har intervjuer och observationer också bidragit till datainsamling. För att uppfylla arbetets syfte och ta fram ett godtyckligt resultat har två frågeställningar tagits fram angående vilka attribut som bör avgöra en artikels position i lagret samt hur en effektivare lagerstruktur kan erhållas. Författarna har gemensamt arbetat fram ett resultat i form av ett förslag för framtida artikelplacering sett till plockfrekvens och tyngd. Inledningsvis genomfördes en nulägesanalys för att identifiera kända problem med artikelplacering och lagersystem. De problem som identifierades var att artikelplaceringen sker utan underlag för plockfrekvens. För att utröna de mest frekventa artiklarna genomfördes en ABC-analys. Samtliga artiklar lokaliserades utspridda över hela lagret. För att ta hänsyn till ytterligare ett kriterium, vilket var tyngd, genomfördes multikriterieanalys i kombination med ABC-analys. Resultatet av den kombinerade analysen gav underlag för att ta fram förslag för framtida artikelplacering. Förslaget innehåller optimerade artikelplaceringar inom olika zoner för de mest plockfrekventa artiklarna med tyngd som ytterligare kriterium.
