AbstrakHipertensi dan rokok merupakan hasil analisis prioritas masalah dengan menggunakan metode USGF (Urgency, Seriousness, Growth, dan Frequency) di dusun Combongan Yogyakarta. Berdasarkan hasil prioritas masalah ini maka diambil suatu upaya pencegahan dan pengendalian dengan melakukan promosi kesehatan pencegahan hipertensi dan perilaku merokok. Kegiatan ini bertujuan untuk meningkatkan pengetahuan warga tentang hipertensi dan bahaya merokok. Harapannya dengan pengetahuan yang baik dapat meningkatkan perilaku yang baik juga dalam pencegahan hipertensi dan perilaku merokok. Metode yang digunakan adalah dengan penyuluhan secara langsung kepada warga dengan menggunakan powerpoint dan juga membagikan leaflet sebagai bahan bacaan. Hasil yang diperoleh adalah kegiatan penyuluhan berjalan dengan baik dan warga peserta penyuluhan aktif bertanya dan mengikuti kegiatan penyuluhan sampai selesai.Penyuluhan dilakukan dengan interaktif antara narasumber dengan warga peserta penyuluhan.Kata kunci: Hipertensi, rokok, penyuluhan.AbstractHypertension and cigarettes are the result of priority analysis of problems using the USGF (Urgency, Seriousness, Growth, and Frequency) method in the Combongan Yogyakarta. Based on the priority results of this problem, an effort to prevent and control is taken by conducting health promotion to prevent hypertension and smoking behavior. This activity aims to increase people's knowledge about hypertension and the dangers of smoking. With good knowledge can improve good behavior also in the prevention of hypertension and smoking behavior. The method used is counseling directly to residents by using powerpoint and also distributing leaflets as reading material. The results obtained were counseling activities went well and the counseling participants actively asked and participated in the extension activities until they were finished. Counseling was carried out interactively between informants and community members.Keywords: Hypertension, cigarettes, counseling.

ABSTRACT A Markov process (chain) of gene frequency change is derived for a geographically-structured model of a population. The population consists of colonies which are connected by migration. Selection operates in each colony independently. It is shown that there exists a stochastic clock that transforms the originally complicated process of gene frequency change to a random walk which is independent of the geographical structure of the population. The time parameter is a local random time that is dependent on the sample path. In fact, if the alleles are selectively neutral, the time parameter is exactly equal to the sum of the average local genetic variation appearing in the population, and otherwise they are approximately equal. The Kolmogorov forward and backward equations of the process are obtained. As a limit of large population size, a diffusion process is derived. The transition probabilities of the Markov chain and of the diffusion process are obtained explicitly. Certain quantities of biological interest are shown to be independent of the population structure. The quantities are the fixation probability of a mutant, the sum of the average local genetic variation and the variation summed over the generations in which the gene frequency in the whole population assumes a specified value.

Abstract Two commonly used population structure software packages are freely available for breed authentication, Structure and Admixture. Structure uses a Bayesian approach to model population structure, while Admixture uses a frequentist approach. More recently, an allele frequency method has been updated to use quadratic programming to constrain the multiple linear regression coefficients of the regression of genotype count (divided by two) on the matrix of allele frequencies for each known breed or line. This constraint forced coefficients to sum to one and be greater than or equal to 0 and less than or equal to 1. The goal of this research was to compare and contrast these three methods to determine the breed/line authenticity for each of the five genetic lines. These five lines included Large White, Landrace, a lean Duroc, a meat quality Duroc, and a Pietrain line. Only animals with a 50K SNP panel were used in this analysis. Analyses were run five times for Structure and Admixture to check repeatability. The allele frequency method did not need to be repeated because it remains the same as long as the reference allele frequency matrix stays constant. For Structure, results of breed composition were inconsistent across replicates. Structure separated at least one of the maternal lines in three out of the five replicates with only 500 animals and kept the Duroc lines together as one population. Only 500 animals could be utilized in each run of Structure due to computational restraints. Admixture was very consistent across runs for each animal, but also failed to separate the two Duroc lines, instead splitting one of the two maternal lines. Finally, the allele frequency method split all five lines correctly and was 100% reproducible as long as the reference allele frequency matrix stays the same across runs.
