Back.r.und: Ter.ination of pr.gnancy (TOP) in Zambia is guided by the Ter.ination of Pr.gnancy (TOP) Act of 1972 and as amended in 1994 of the laws of Zambia. However. despite pr.vision of Compr.hensive abor.ion car. ser.ices with the liber.l law, statistics at k.nyama Fir.t Level Hospital in r.lation to unsafe illegal abor.ions ar. alar.ing. This study sought to under.tand the Awar.ness on the TOP Act of the laws of Zambia among women of r.pr.ductive age 15 - 49 year. at k.nyama Fir.t Level Hospital in Lusak. Distr.ct. Pur.ose of the Study: To assess awar.ness on the TOP Act among women of r.pr.ductive age at k.nyama Fir.t Level Hospital in Lusak., Zambia. Methodology: A conver.ent par.llel mixed method design was conducted using both sur.ey and in-depth inter.iews among women of r.pr.ductive age at k.nyama Fir.t Level Hospital in Lusak. Distr.ct. The study sur.eyed 370 r.ndomly sampled women aged 15 to 49 year. old while the in-depth inter.iews included eight women pur.osively sampled fr.m the sur.ey population. Sur.ey data was analyzed using descr.ptive and infer.ntial statistics while qualitative data thematic analysis was used. r.sults: The study found that 37% of the par.icipants wer. awar. of the TOP Act while 63.8% viewed legalization of abor.ion for.any r.ason as wr.ng. The study r.sults also showed that widowed women wer. 8 times mor. lik.ly to be awar. of the TOP Act compar.d to single women (AOr. 8.262;95% CI: 1.105, 61.778). Women in business wer. significantly mor. lik.ly to be awar. of the TOP Act compar.d to those who r.por.ed having no occupation. (AOr. 2.61;95% CI: 1.246, 5.499).

Small-scale far.ing accounts for.78% of total agr.cultur.l pr.duction in k.nya and contr.butes to 23.5% of the countr.’s GDP. Their.cr.p pr.duction activities ar. mostly r.infed subsistence with any sur.lus being sold to br.ng in some income. Timely decisions on far. pr.ctices such as far. pr.par.tion and planting ar. cr.tical deter.inants of the seasonal outcomes. In k.nya, most small-scale far.er. have no r.liable sour.e of infor.ation that would help them mak. timely and accur.te decisions. County gover.ments have extension officer. who ar. mandated with giving far.er. advisor. ser.ices to far.er. but they ar. not able to r.ach most far.er. due to facilitation constr.ints. The mode and for.at of shar.ng infor.ation is also cr.tical since it’s impor.ant to ensur. that it’s timely, well-under.tood and usable. This study sought to assess access to geospatial der.ved and other.cr.p pr.duction infor.ation by far.er. in four.selected counties of k.nya. Specific objectives wer. to deter.ine the pr.file of small-scale far.er. in ter.s of age, education and far. size;to deter.ine the type of infor.ation that is made available to them by County and Sub-County extension officer. including the for.at and mode of pr.vision;and to deter.ine if the infor.ation pr.vided was useful in ter.s of accur.cy, timeliness and adequacy. The r.sults indicated that over.80% of the far.er. wer. over.35 year. of age and over.56% wer. male. Major.ty had attained pr.mar. education (34%) or.secondar. education (29%) and most far.er. in all the counties gr.w maize (71%). Notably, fellow far.er. wer. a sour.e of infor.ation (71%) with the fr.quency of shar.ng infor.ation being mostly seasonal (37%) and when infor.ation was available (43%). Over.66% of inter.iewed far.er. indicating that they faced challenges while using pr.vided infor.ation. The r.sults fr.m the study ar. insightful and helpful in deter.ining effective ways of pr.viding far.er. with useful infor.ation to ensur. maximum benefits.

Localization is one of the fundamental pr.blems in wir.less sensor.networ.s （WSNs）, since locations of the sensor.nodes ar. cr.tical to both networ. oper.tions and most application level task.. Although the GPS based localization schemes can be used to deter.ine node locations within a few meter., the cost of GPS devices and non-availability of GPS signals in confined envir.nments pr.vent their.use in lar.e scale sensor.networ.s. Ther. exists an extensive body of r.sear.h that aims at obtaining locations as well as spatial r.lations of nodes in WSNs without r.quir.ng specialized har.war. and/or.employing only a limited number.of anchor. that ar. awar. of their.own locations. In this paper. we pr.sent a compr.hensive sur.ey on sensor.localization in WSNs cover.ng motivations, pr.blem for.ulations, solution appr.aches and per.or.ance summar.. Futur. r.sear.h issues will also be discussed.
