Energy self-reliance is important for economic growth and development for any nation. An energy self-reliance technological analysis for Kampala the capital city of Uganda is presented. Three renewable energy sources: Municipal Solid Waste (MSW), solar and wind are assessed for the period of 2014 to 2030. Annual MSW generation will increase from $6.2{\times}10^5$ tons in 2014 to $8.5{\times}10^5$ and $1.14{\times}10^6$ tons by 2030 at 2% and 3.9% population growth respectively. MSW energy recovery yield varies from 136.7 GWh (2014, 65% collection) to 387.9 GWh (2030, 100% collection). MSW can at best contribute 2.1% and 1.6% to total Kampala energy demands for 2014 and 2030 respectively. Wind contribution is 5.6% and 2.3% in those respective years. To meet Kampala energy demands through solar, 26.6% of Kampala area and 2.4 times her size is required for panel installation in 2014 and 2030 respectively. This study concludes that improving renewable energy production may not necessarily translate into energy self-reliant Kampala City based on current and predicted conditions on a business as usual energy utilization situation. More studies should be done to integrate improvement in renewable energy production with improvement in efficiency in energy utilization.

Slum settlement, a direct result of the rapid worldwide urbanization is a common site in most developing countries. Uganda is among the top African countries with high number of slums. The status of Katanga slum located in the low-lands between Mulago national hospital and Makerere University is a typical of many other slums within Uganda. This project proposal seeks to tackle urbanization challenges by specializing in slum upgrading as a sustainable way of curbing the menace. An integrated toilet, biogas, poultry and backyard gardening project is proposed as a channel of boosting the Katanga slum dwellers' economic, sanitation and domestic energy status. Designed to serve up to 30 households, the project will utilize residual wastes from poultry houses and toilets to produce biogas and slurry. The biogas yield will provide clean cooking fuel and energy for lighting, while the slurry used as organic fertilizers to improve vegetable yields. The social, economic and environmental impacts of the project will empower the vulnerable women and children within the slums and reduce water pollution and land degradation. This affordable project can be applied in developing countries experiencing slum settlement challenges as a strategy for reducing urbanization pressure.

최근 급속한 세계화로 인해 물류 아웃소싱이 전 세계적으로 확대되고 있으며, 이것은 견고한 물류시스템을 구축하는 수단으로 간주되고 있다. 그러나 많은 기업이 물류 아웃소싱 계약에 어려움을 겪고 있어 기업의 내부 관리를 위해 물류 기능을 회복해야 하는 어려움이 계속되고 있다. 본 연구는 유연성, 통합, 혁신 및 기술 역량과 같은 물류 서비스 제공자(LSP)의 조직 역량이 우간다 식품 가공 회사의 물류 아웃소싱 성공에 어떤 영향을 미치는지 평가하는 것을 목표로 한다. 구조화된 설문조사를 이용하여 우간다 캄팔라에 있는 211개 식품 가공 회사에서 수집한 횡단면 데이터를 SmartPLS 3.3.7 소프트웨어를 통한 PLS-SEM(부분 최소제곱-구조방정식 모형화)으로 분석하여 이론적 관계를 검토하였다. 연구 결과에 따르면 기술 및 혁신 역량은 물류 아웃소싱 성공에 긍정적이고 상당한 영향을 미치지만, 유연성 및 통합 역량의 효과는 미미한 것으로 나타났다. 또한 중요도성과분석(IPMA) 결과 물류 아웃소싱 성공을 위해서는 기술 역량이 우선순위가 가장 높고 그다음이 혁신 역량인 것으로 나타났다. 그러나 유연성과 통합 역량은 우선순위가 낮았다.
