A projeção chinesa na África Subsaariana: situação da república democrática do Congo

TCC (graduação) - Universidade Federal de Santa Catarina. Centro Sócio-Econômico. Economia.Este trabalho trata das características e implicações da projeção Chinesa na África Subsaariana. A pesquisa é sobre a Republica Democrática do Congo (RDC), mostrando como a China vem atuando naquele país, motivada pela existência de importantes recursos. O objetivo maior é descrever e discutir a presença da China na África subsaariana, no século XXI, destacando a situação da Republica Democrática do Congo. O Congo tem sido reconhecido como um dos países mais ricos em minério do planeta. Possui reservas substanciais de cobre, cobalto, cádmio, petróleo, diamantes, ouro, prata, zinco, manganês, estanho (cassiterita), coltan. Em relação aos recursos naturais da República Democrática do Congo, importa que o potencial de ouro do país é quase inexplorado, enquanto a abundância de diamantes é pouco controlada. Metodologicamente tipo de pesquisa mais adequada seria a exploratória com coleta de dados a partir de fontes bibliográficas ligados a conceitos e fundamentos teóricos que dão suporte ao problema proposto. Concluiu-se que, a China está em franco crescimento e dependente de matéria prima, o RDC tem dificuldades econômicas, precisa de aporte financeiro e possui matéria prima em abundância. Esses fatores levaram a China e RDC efetivarem um acordo de cooperação. A China se comprometeu a investir na região, em contrapartida congolesa deixar explorar suas riquezas. Contudo, verifica-se que mesmo com a enormidade do investimento chinês frente à mineração no Congo, existe uma enorme pobreza da população

Nutrient Removal by Rice Cultivated in Newly Opened Wetland Rice in Bulungan District, East Kalimantan

Highly weathered Indonesian soils and potential acid sulphate soils are mainly granted for developing newlyopened wetland rice field to meet rice growing demand in Indonesia. Nutrient removal by rice harvest product ofCiliwung variety planted in newly opened wetland rice was studied in Bulungan District, in 2009. The aims were toexamine the nutrient taken out by rice harvest product and to properly manage its fertility status to sustain ricefarming. Six treatments were studied including T0: farmers practices, T1: farmer practices + compost + dolomite, T2:NPK recommended rate, N and K were split two times, T3: NPK recommended rate, N and K were split three times,T4: NPK recommended rate, N and K were split three times + compost + dolomite and T5: NPK recommended rate,N and K were split two times + compost + dolomite. The results indicated that the highest concentrations of N, P,and K in rice grain and rice straw were observed at NPK with recommendation rate in which N and K were split threetimes + straw compost + dolomite (T4). The T4 (NPK with recommendation rate in which N and K were split threetimes + straw compost + dolomite) also showed the highest nutrient removal by harvest product. Depending on thetreatments, total nutrients removal through rice grains and rice straw varied from 61.81 to 101.71 kg N, 4.31 to13.69 kg P and from 95.77 to 171.16 kg K ha-1 season-1, meaning that at least about 137 to 225 kg urea, 50 to 160kg SP-36 and 190 to 339 kg KCl ha-1 season-1 should be given to replace nutrient removed by harvest product andto avoid any nutrients depletion. When all rice straws were returned to the field as compost, about 55 to 133 kg urea,25 to 110 kg SP-36 and 10 to 19 kg KCl ha-1 season-1 should be added to substitute nutrient removed by rice grain.[How to Cite: Sukristiyonubowo, K Nugroho and T Vadari. 2012.

Narrative and its closely related counterpart storytelling are most often thought of as modalities for entertainment. Regardless, narrative has long been a part of the repertoire of tools employed by instructors, trainers, and educators to achieve their pedagogical goals. Psychologists have recognized narrative as relevant to the way we store and make sense of episodic experience, often described as the phenomenon of narrative construction of reality. Recent research, especially pertaining to artificial intelligence, have demonstrated intelligent learning environments that incorporate narrative to form of "Edutainment " and "Serious Games, " effectively blending in computer game play to achieve more engaging and distributable learning and training applications. A Narrative Learning Environment (NLE) is a type of Intelligent Learning Environment (ILE) in which narrative is a key instrument in facilitating teaching and learning. Due to the explorative and complex nature of narrative, an intelligent learning environment based on a narrative approach can promote several kinds of activities for learners
