Urban Liveability in Nigeria-A Pilot Study of Ago-lwoye and Ijebu-lgbo in Ogun State

This study examines the state of liveability in emerging urban centers of Ago-lwoye and Ijebu-Igbo in Ogun State. The study used primary and secondary data. Both descriptive and inferential statistical techniques were used to analyze research questions that bother on urban liveability. Results of the analyses show that in the two urban centres the following are not in very good condition： neighborhood road quality, garbage collection, state of cleanliness, street light, state of security, pollution, water supply, drainage system, and power supply. Most of the residents are not satisfied with the state of liveability in Ago-Iwoye and Ijebu-Igbo towns. Statistical test result shows among others that there is no significant variation in the level of urban dwellers＇ satisfaction with their neighbourhood condition. In order to improve urban liveability in the two urban centres, government should provide all necessary infrastructural facilities and services. While roads are to be improved and maintained, electricity and water supply should be provided. Community associations should also be encouraged. They should be more involved in activities that will improve liveability in the urban centre. They should constitute themselves as pressure groups, working on the government to improve the liveability of the urban centre.

城市电网建设与改造工程中变电所设计模式研究

城市电网建设与改造项目优化设计至关重要,能显著提升电力供应质量,使电网系统运行更加安全、稳定。在电力建设中,需要制订系统完整的方案,不仅要考虑近期实际情况,而且要兼顾长远目标,通过不断更新理念、加强技术应用,显著提升城市电网服务能力,并完善改造项目工程,确保电网建设的可靠性。为实现该目标,应改造电网结构,在结构设计中,应考虑设计原则是否满足城市电网设计导则,严格要求项目设计的可靠性。
