PEMANFAATAN REPRESENTASI DALAM MENYELESAIKAN PERMASALAHAN PADA MATERI SPLDV

This study aims to look at and describe students' representation abilities in the matter of a system of two-variable linear equations (SPLDV) after the application of the Problem Based Learning (PBL) model. The research method used was descriptive with quantitative and qualitative data analysis according to the indicators of mathematical representation. This research was conducted at SMPN 6 Indralaya Utara in class VIII 1 involving 28 students as subjects. Data collection was carried out by giving tests in the form of description questions and the results of interviews with students. The collected data was subsequently examined using scoring criteria that make reference to indicators of mathematical representation. After that, the outcome of the data analysis was divided into three groups: high, medium, and low. Based on the results of data analysis, it was found that students' mathematical representation abilities in the matter of a two-variable linear equation system after the implementation of the PBL model were in the medium category with an average score of 51.12 and an average score for the symbolic representation indicator that was 75, visual representation 48 .21 and verbal 33.04

PELAKSANAAN PENYIDIKAN KASUS DUGAAN KORUPSI PENGADAAN ALAT KESEHATAN RSUD dr RASIDIN PADANG OLEH POLRESTA PADANG

ABSTRAK Masalah korupsi adalah masalah yang besar yang sedang dihadapi negara saat ini. Korupsi merupakan suatu penyakit dalam masyarakat dan merupakan suatu hal yang dapat menghambat jalannya pembangunan di negara kita saat ini. Oleh karena itu, korupsi merupakan salah satu penyakit yang harus segera diberantas. Tindak pidana korupsi yang terjadi di Indonesia sebagian besar berasal dari pengadaan barang dan jasa. Dari 468 kasus tindak pidana korupsi yang ditangani KPK, 50 persen atau sedikitnya 224 kasus berasal dari pengadaan barang dan jasa. Selebihnya merupakan kesalahan dalam menggunakan anggaran. Penelitian ini bertujuan untuk mengetahui bagaimana Pelaksanaan Penyidikan Kasus Dugaan Korupsi Pengadaan Alat Kesehatan RSUD dr Rasidin Padang Oleh Polresta Padang. Penelitian ini dilaksanakan di Polresta Kota Padang.

Whole-Retina Reduced Electrophysiological Activity in Mice Bearing Retina-Specific Deletion of Vesicular Acetylcholine Transporter

Background: Despite rigorous characterization of the role of acetylcholine in retinal development, long-term effects of its absence as a neurotransmitter are unknown. One of the unanswered questions is how acetylcholine contributes to the functional capacity of mature retinal circuits. The current study investigates the effects of disrupting cholinergic signalling in mice, through deletion of vesicular acetylcholine transporter (VAChT) in the developing retina, pigmented epithelium, optic nerve and optic stalk, on electrophysiology and structure of the mature retina. Methods & Results A combination of electroretinography, optical coherence tomography imaging and histological evaluation assessed retinal integrity in mice bearing retina-targeted (embryonic day 12.5) deletion of VAChT (VAChT(Six3-Cre-flox/flox)) and littermate controls at 5 and 12 months of age. VAChT(Six3-Cre-flox/flox) mice did not show any gross changes in nuclear layer cellularity or synaptic layer thickness. However, VAChT(Six3-Cre-flox/flox) mice showed reduced electrophysiological response of the retina to light stimulus under scotopic conditions at 5 and 12 months of age, including reduced a-wave, b-wave, and oscillatory potential (OP) amplitudes and decreased OP peak power and total energy. Reduced a-wave amplitude was proportional to the reduction in b-wave amplitude and not associated with altered a-wave 10%-90% rise time or inner and outer segment thicknesses. Significance This study used a novel genetic model in the first examination of function and structure of the mature mouse retina with disruption of cholinergic signalling. Reduced amplitude across the electroretinogram wave form does not suggest dysfunction in specific retinal cell types and could reflect underlying changes in the retinal and/or extraretinal microenvironment. Our findings suggest that release of acetylcholine by VAChT is essential for the normal electrophysiological response of the mature mouse retina

As práticas relacionadas ao uso popular de diversas plantas medicinais são empregadas enquanto alternativa viável ao uso de medicamentos industrializados. O senso comum serve como base para o tratamento e cura de diversas condições adversas à saúde da população. Dentre as plantas medicinais destaca-se a Lippia alba, que possui diversos nomes populares sendo o mais conhecido erva-cidreira que, de acordo com o conhecimento científico, possui um rico potencial farmacológico que está relacionado à ampla variação na composição química de seu óleo essencial. Este estudo tem como objetivo realizar uma revisão da literatura, fazendo uso da metassíntese enquanto instrumento metodológico, para verificar a existência de informações na literatura científica que evidenciem assertividade do conhecimento popular acerca do potencial de ação da Lippia alba (Mill.) N. E. Brown ou se tal uso se constitui enquanto simples placebo. Para a realização da pesquisa foram utilizadas as bases de dados Periódicos CAPES, LILACS e Scielo. Como estratégia de busca utilizou-se os seguintes Indexadores: “Plantas medicinais”; “Lippia alba”; “práticas populares”. O período da pesquisa incluiu artigos publicados entre janeiro de 1998 a dezembro de 2013. Observou-se com o estudo a existência de pelo menos 25 indicações, onde o uso da Lippia alba torna-se eficaz.

Práticas de gestão de pessoas: uma análise das melhores cooperativas para trabalhar

 The present study had the objective of identifying the main practices of people management adopted by the best cooperatives to work, according to a ranking of the magazine Você S/A of 2017. In order to meet the objective, a descriptive and qualitative and quantitative research was carried out. The data collection was based on documentary analysis, through the consultation of the magazine Você S/A with the Best Companies to Work in 2017, as well as access to the website and the sustainability and management reports for the year 2017 of the cooperatives. It can be noticed that the 16 cooperatives awarded belong to two branches, credit and health. With regard to people management practices, the two cooperatives have established practices. In the credit sector, there was greater expressiveness in endomarketing and training and development. While in the health sector, the most significant factors were, social benefits and T&D.The present study had the objective of identifying the main practices of people management adopted by the best cooperatives to work, according to a ranking of the magazine Você S/A of 2017.

Elimination of the vesicular acetylcholine transporter in the forebrain causes hyperactivity and deficits in spatial memory and long-term potentiation

Basal forebrain cholinergic neurons, which innervate the hippocampus and cortex, have been implicated in many forms of cognitive function. Immunolesion-based methods in animal models have been widely used to study the role of acetylcholine (ACh) neurotransmission in these processes, with variable results. Cholinergic neurons have been shown to release both glutamate and ACh, making it difficult to deduce the specific contribution of each neurotransmitter on cognition when neurons are eliminated. Understanding the precise roles of ACh in learning and memory is critical because drugs that preserve ACh are used as treatment for cognitive deficits. It is therefore important to define which cholinergic-dependent behaviors could be improved pharmacologically. Here we investigate the contributions of forebrain ACh on hippocampal synaptic plasticity and cognitive behavior by selective elimination of the vesicular ACh transporter, which interferes with synaptic storage and release of ACh. We show that elimination of vesicular ACh transporter in the hippocampus results in deficits in long-term potentiation and causes selective deficits in spatial memory. Moreover, decreased cholinergic tone in the forebrain is linked to hyperactivity, without changes in anxiety or depression-related behavior. These data uncover the specific contribution of forebrain cholinergic tone for synaptic plasticity and behavior. Moreover, these experiments define specific cognitive functions that could be targeted by cholinergic replacement therapy
