Trend Analysis of Teenage Pregnancy in Nigeria (1961-2013): How Effective is the Contraceptive Use Campaign

Teenage pregnancy (TP) is a recurrent global and public health problem. It poses both social and health challenges. Considering the massive campaign on the use of modern contraceptives to prevent TP in recent decades, we assessed trends in TP in Nigeria between 1961 and 2013. Pregnancy and contraception history of 70,811 women who were at least 20 years old when the Nigerian DHS was conducted in 1990, 2003, 2008, and 2013 respectively were used for the study, and descriptive statistics, time analysis techniques and multiple logistic regression were used to analyze the data at 5% significance level. The overall prevalence of TP between 1961 and 2013 was 49.5% which fluctuated insignificantly during the studied period. The TP prevalence among women who entered adulthood in 1961 was 39.2%; it peaked in 1978 at 58.9% before its unsteady decline to 39.6% in 2012, and then rose sharply to 55.6% in 2013. We predicted TP prevalence as 49.0%, 49.9% and 51.0% in 2014, 2015 and 2016 respectively. The odds of TP were over 4 times higher in the North East and 5 times higher in the North West than in the South West. Teenagers with no education had higher odds of TP and it was higher among teenagers from the poorest households (OR=5.64, 95% CI: 5.36-5.94). Rather than reducing with the worldwide acknowledged increase in contraceptive campaigns, TP increased over the years studied. As far as TP is concerned in Nigeria, the impact of the campaign on MC use is far from being effective. To achieve the objective of fewer TPs, fewer resources should be spent on access to contraception and instead diverted to areas more likely to achieve results such as improvements in educational achievement amongst girls

Karakteristik Spent Ore Proses Heap Leach Single Stacking Berdasarkan Uji Xrd, Xrf dan Mikroskop Bijih terhadap Potensi Pembentukan Air Asam Tambang

Teknologi pengolahan emas dengan sianidasi metode heap leach single stacking merupakan pengolahan dengan cara menyiramkan larutan sianida keatas tumpukan bijih yang dapat melarutkan logam berharga tanpa melarutkan pengotornya. Batuan sisa pengolahan emas (spent ore) mengandung mineral sulfida dapat berpotensi dalam pembentukan air asam tambang sehingga perlu diketahui pengaruh mineralogi spent ore emas terhadap pembentukan air asam tambang. Penelitian ini bertujuan: (1) mengetahui karakteristik mineralogi batuan spent ore berdasarkan uji geokimia dan petrologi batuan, (2) mengetahui pengaruh mineralogi terhadap terbentuknya air asam tambang proses heap leach single-stacking. Penanganan air asam tambang langkah awal yang harus dilakukan yaitu dengan karakterisasi mineralogi batuan spent ore. Metode yang digunakan untuk mengetahui mineralogy batuan yaitu dengan pengujian mineralogi dengan analisis XRD (X-ray Diffractions), analisis XRF (X-Ray Fluoresence), dan pengamatan mikroskop bijih. Hasil analisis menunjukkan bahwa mineralogi spent ore emas proses head leach berpengaruh terhadap pembentukan air asam tambang

Analisis Pendapatan, Pertumbuhan Dan Struktur Ekonomi Nasional

This paper aims to find out fluctuations in income growth and national economic growth in 2004 - 2008, as one of the important information in the development of national economy, especially to determine the role of development and growth of economic sectors in the national economy. Analysis was performed by diskrptif. While the national income accounts approach based on the Central Bireau of Statistics (BPS) and national economic growth based on the model of growth developed by Roy F.Harrod and Evsey Domar. So that economic growth is simply defined as an increase in total long-term output. The hypothesis of this writing, that the role and growth of industrial sector tended to increase more than other sectors. This has evidenced with the role and growth of every sector of national income as measured by GNP based on constant price and current price

Penerapan Analisis Fundamental Dengan Metode Price Earning Ratio (Per) Untuk Penilaian Kewajaran Harga Saham Dan Keputusan Investasi (Studi Pada Perusahaan Subsektor Food and Beverage Yang Terdaftardi Bei Periode 2011-2013)

The purpose of this research is reasonable to know the price of Food and Beverage company shares subsector lested in the Indonesian Stock Exchange( BEI ) based on fundamental analysis by using PER method, also to know the proper investment decision , (buy, sell or hold).The results of research in 2011 the condition of a share DLTA, ICBP, INDF, MYOR, ROTI in the overvalued condition, then an investment decision proper is sell stocks when they have a share and for the future should hold investors not to buy shares the company, shares of MLBI in aundervalued condition and an investment decision proper is buy shares of the company and holding not to sell. In 2012 the total sample research company in overvalued condition and an investment decision proper is sell stocks for those who have a share and investors not to buy for the future. 2013 only shares of ROTI in aundervaluedcondition and an investment decision that right is to buy company shares is for prospective investors and hold to sell to investors who have shares of the company. The state of stock DLTA, ICBP, INDF, MLBI, MYOR, in a overvalued condition, An investment decision that can be taken in a state of overvalued shares stock was selling for those who have have a share or holding for investors not to buy for the future
