Recently, we proposed stochastic point-based rendering, which enables precise and interactive-speed transparent rendering of large-scale laser-scanned point clouds. This transparent visualization method does not suffer from rendering artifact and realizes correct depth feel in the created 3D image.

In this paper, we apply the method to several kinds of large-scale laser-scanned point clouds of cultural heritage objects and prove its wide applicability.

In addition, we prove better image quality is realized by properly eliminating points to realize better distributional uniformity of points. Here, the distributional uniformity means uniformity of inter-point distances between nearest-neighbor points.

We also demonstrate that highlighting feature regions, especially edges, in the transparent visualization helps us understand 3D internal structures of complex laser-scanned objects. The feature regions are highlighted by properly increasing local opacity of the regions.

Mobile mapping systems (MMS) can capture point cloud and continuous panoramic images of roads and their surrounding environment. These data are widely used for the maintenance of road-side objects and the creation or update of road ledgers. For these purposes, there is a need to detect and classify each object from captured data, and localize them on 3D maps. Many studies have been reported on the detection and classification of pole-like objects using point clouds captured by a mounted laser scanner. Although MMS images contain valuable information related to color and shape about objects, they have not been well utilized to date for this purpose. It is reasonable to extract shape and color features from images and use them for classification. In this paper, we focus on MMS images rather than point clouds, and evaluate the classification performance for pole-like objects, such as power poles, street lamps, street-side tree, signal lights, and road signs. For classification, Convolutional Neural Network (CNN) is used, because it is known to provide better classification results than conventional methods where hand crafted features and machine learning techniques are commonly used. We also use image super resolution (ISR) techniques based on deep learning for MMS low-resolution images. In contrast to conventional methods in which entire points of pole-like objects are evaluated, our approach selects functional parts attached to the top of the pole (e.g., three-color traffic lights) for classification, because these parts represent unique characteristics of each class of object. We demonstrate the classification performance of our proposed approach through various experiments using MMS images. We also compare the difference in classification results depending on the imaging angles.

When we drive a car, the white lines on the road show us where the lanes are. The lane marks act as a reference for where to steer the vehicle. Naturally, in the field of advanced driver-assistance systems and autonomous driving, lane-line detection has become a critical issue. In this research, we propose a fast and precise method that can create a three-dimensional point cloud model of lane marks. Our datasets are obtained by a vehicle-mounted mobile mapping system (MMS). The input datasets include point cloud data and color images generated by laser scanner and CCD camera. A line-based point cloud region growing method and image-based scan-line method are used to extract lane marks from the input. Given a set of mobile mapping data outputs, our approach takes advantage of all important clues from both the color image and point cloud data. The line-based point cloud region growing is used to identify boundary points, which guarantees a precise road surface region segmentation and boundary points extraction. The boundary points are converted into 2D geometry. The image-based scan line algorithm is designed specifically for environments where it is difficult to clearly identify lane marks. Therefore, we use the boundary points acquired previously to find the road surface region from the color image. The experiments show that the proposed approach is capable of precisely modeling lane marks using information from both images and point cloud data.

Simulator Optimizes Gas Lift Unloading
Authors: JPT staff _
Published: April 2018

This article is a synopsis of paper SPE 29450, "Gas-Lift Unloading and Operating Simulation as Applied to Mandrel Spacing and Valve Design" by James W. Hall, SPE, Producing Solutions and Kenneth L. Decker, SPE, Decker Technology, originally presented at the 1995 SPE Production Operations Symposium, Oklahoma City, OK April 2-4. Please read the full-length paper for additional detail, illustrations, and references.

Gas lift has been practiced for many years with principles developed on experience and "rules of thumb" with little regard for actual valve performance. Available software now simulates the unloading and operation of gas lift wells by use of scientific principles and valid "valve-performance" data.

In a conventional configuration, the tubing/ casing annulus is initially filled with a completion fluid from the packer to the surface. To initiate gas lift, the fluid must be removed from the annulus to uncover the installed flow-control device at the desired point of gas injection into the tubing. This process of removing the completion fluid is referred to as "unloading" the annulus.

Various procedures for unloading the annulus have been recommended. When recommending changes of injection rate and pressure, these procedures ignore the actual performance of the gas lift valve under downhole conditions. For this paper, valve performance data are defined as the quantitative measure of a valve's flow-rate response to changes in casing and/or tubing pressure for a given pressure and temperature setting.

Vendors supply tables and figures to predict gas-flow rates for their equipment. The information is presented in different formats and no algorithm is available to compare valve performance of different manufacturers. Additionally, the data are focused on gas-flow, making liquid-flow predictions difficult. Therefore, the unloading process cannot be optimized with these data.

API RP 11 V2 outlines a procedure for obtaining performance data of gas lift valves. The procedure is not required and must be requested by the end user. Tests are being performed and results are available. Computer applications applying the valve-performance data have been developed.

Another error in some applications is the assumption that gas lift valves are fully open immediately after opening and before closing. This is true only for pilot and differential- pressure-operated valves.

The application of valve-performance data to engineering solutions is still not a standard practice. Tools are available to design annulus-unloading procedures for the unique parameters for each well. Prudent operators will be able to examine mandrel spacing and valve design before installation to ensure proper performance, to reduce valve damage, and to eliminate multipoint injection.

Published: April 2018

Campylobacter is an important cause of gastrointestinal illness and exposure to recreational water is one potential source of infection. The objective of this study was to investigate the presence and concentrations of Campylobacter, and determine the influence of agricultural activities and precipitation on their presence, at lake beaches used for water recreation in southern Quebec, Canada. A total of 413 water samples were collected from June to August, from 22 beaches, between 2011 and 2013. The overall proportion of positive water samples was estimated to be 33.9% (95% CI: 27.7, 40.1) for C. jejuni and 49.7% (95% CI: 41.8, 57.6) for Campylobacter spp. The concentrations of both thermotolerant Campylobacter spp. and C. jejuni ranged from 20 to 900 bacteria/L of water. Logistic regressions showed that the presence of C. jejuni and Campylobacter spp. was significantly associated with the year and season. Other significant predictors of C. jejuni, but not Campylobacter spp., included the presence of precipitation the day before sampling and the presence of ruminant farms within a 5 km radius of the beach. The present study provides insights into the risk of Campylobacter presence in recreational lake water for better understanding public health risks.

Ensayo y error. Un análisis marxista de las políticas públicas
Authors: Álvarez Huwiler Laura , Bonnet Alberto
Published: April 2018

Este artículo aborda la problemática de la racionalidad del proceso de formulación de políticas públicas y su objetivo es esbozar lineamientos desde una perspectiva distinta de la concepción racionalista. Propone como hipótesis que el proceso de políticas públicas constituye un ensayo y error signado por una racionalidad acotada. Aunque estos conceptos provienen del debate “racionalistas/incrementalistas”, aquí se redefinen a partir de un análisis del Estado capitalista y de los límites que le impone a su capacidad de intervenir conforme a los requerimientos de la reproducción capitalista, enmarcado en la vertiente derivacionista de la teoría marxista del Estado. El artículo constituye un trabajo teórico-metodológico, apoyado en observaciones propias del marco de investigaciones empíricas sobre procesos concretos de políticas públicas.
Mortalidad y años potenciales de vida perdidos por causas externas: Colombia 1998-2015
Authors: Segura-Cardona Alejandra , Cardona-Arango Doris
Published: April 2018

Introducción: Las causas externas de mortalidad se constituyen en un problema de salud pública, afectan a población joven, tienen pertinencia social, son evitables y su impacto es reducible a largo plazo.  Objetivo: Describir el comportamiento de la mortalidad por causas externas y de los años potenciales de vida perdidos en la población colombiana entre 1998-2015.  Materiales y métodos: Estudio analítico de cuatro grandes grupos de mortalidad externa: homicidio, suicidio, accidente de tránsito y otras causas; de 641.837 certificados de defunción. Se calcularon tasas de mortalidad, crudas y estandarizadas con método directo en tres períodos de tiempo y años potenciales de vida perdidos, para cada grupo. Resultados: El riesgo de morir por causas externas fue de 81,66 por cien mil habitantes, con una disminución del 47,1% y 37,6 años potenciales de vida perdidos. Por homicidio, se registró una tasa de 47,3 por cien mil habitantes, reducción del 59,3% y 23 años potenciales de vida perdidos; los accidentes de tránsito registraron una reducción del 30,3% con una tasa de 15,7. El suicidio registró menor reducción en los 18 años (9,8%) y una tasa promedio de 5,1. Conclusión: Las muertes por causas externas son prioritarias a la hora de plantear políticas públicas, principalmente para la disminución de homicidios que son un reflejo del conflicto armado y la delincuencia que afronta el país, generando la pérdida de años de vida productivos para la sociedad. Es necesario perfilar a los victimarios para focalizar e intervenir las poblaciones más afectadas.

Jornalismo, Memória e Testemunho: Uma análise do tempo presente
Authors: Gerk Cristine , Barbosa Marialva
Published: April 2018

O objetivo do artigo é relacionar jornalismo e memória, a partir do maior vínculo entre eles: o testemunho. A análise tem como apoio metodológico uma pesquisa realizada com 103 jornalistas do Rio de Janeiro no primeiro semestre de 2017 sobre seus ícones na profissão. O resultado é interpretado com o respaldo teórico de pesquisadores da memória, como Barbie Zelizer, Andreas Huyssen, Maurice Halbwachs e Philippe Joutard. A questão do testemunho é estudada em duas dimensões: o testemunho como ferramenta histórica de produção do jornalismo e o testemunho do jornalismo sobre si mesmo, em um tempo acelerado, que privilegia o presente em detrimento do passado ou do futuro.

Published: April 2018

A construção de militâncias intelectuais, especialmente as que se apresentavam a partir de novos significados discursivos para a escola contemporânea, se deu a partir de disputas fomentadas na transição dos séculos XIX e XX. Nesse sentido, todo um cabedal de protagonismos do qual a Igreja católica se ressentia, estava assentado em verdadeira guerra de modelos instrucionais. No âmbito de uma maior presença da secularização social e cultural, se fez apresentar como instrumental de afirmação da Igreja, a temática da escola confessional. Em muitas dioceses espalhadas pelo mundo, encíclicas papais, lançavam propostas educacionais nas quais instituições católicas eram apontadas como solução para um mundo cada caracterizado como indiferente, mundano e laico. Nosso artigo, partindo da leitura do periódico diocesano A Imprensa, discute a representação das querelas textuais a partir dos conceitos de Nestor Garcia Canclini, sobre hibridismo cultural. Para tanto, lançamos mão da análise dos postulados elaborados pelos articulistas locais, tanto no tocante ao universo escolar confessional, quanto dos intelectuais secularistas. Estes últimos a partir de Fernando Catroga, que identifica-os enquanto intelectuais que defendem os signos da religião civil, nos regimes republicanos.

Authors: Costa Rodrigo
Published: April 2018

O objetivo deste artigo é analisar a reorganização do PCB em Alagoas entre 1980 e 1982. A atenção recairá inicialmente nos dois processos paralelos que envolveram, de um lado, a reorganização do Partido em nível nacional, com o retorno do Comitê Central, o qual se encontrava exilado desde meados da década de 1970; de outro, as estratégias adotadas pelos comunistas alagoanos para a reestruturação da agremiação no estado. Antes da profunda atuação na campanha pela Anistia, as articulações para as eleições legislativas de 1978 foram um marco no trabalho da militância pecebista alagoana, ao mesmo tempo em que possibilitaram a entrada de um grupo de jovens estudantes os quais, juntamente com os antigos comunistas deram o passo decisivo para restabelecer a atuação política do Partido em Alagoas a partir do ano de 1980.

Bu çalışmanın amacı, okul öncesi sınıflarındaki öğrenme merkezlerinin durumunu belirlemek ve öğretmenlerin öğrenme merkezleri hakkındaki görüşlerini incelemektir. Araştırma, nitel araştırma yöntemlerinden durum çalışması modeline göre gerçekleştirilmiştir. Çalışma grubunda toplam 7 farklı anaokulunda bulunan 10 okul öncesi sınıfı ve bu okul öncesi sınıflarında çalışan 10 okul öncesi öğretmeni yer almıştır. Araştırmada veriler, gözlem ve görüşme tekniğiyle toplanmıştır. Araştırma sonucunda, öğrenme merkezlerinin ve bu merkezlerdeki materyallerin/oyuncakların yeterli sayıda ve çeşitte olmadığı; çocukların en çok blok merkezi ve dramatik oyun merkezini kullandıkları; fen ve doğa, müzik ve kitap merkezinin en az kullanılan merkezler olduğu; kız çocuklarının en çok dramatik oyun merkezi ve sanat merkezini, erkek çocuklarının ise en çok blok merkezini tercih ettikleri bulunmuştur. Ayrıca, sınıflarındaki öğrenme merkezlerini yeterli bulmayan öğretmenler bunun nedeni olarak okulun maddi yetersizliğini göstermiş ve bunun için kendilerinin sınıfa evden materyal/oyuncak getirdiklerini ya da satın aldıklarını, bazen merkezleri değiştirdiklerini ya da velilerden destek istediklerini belirtmişlerdir. Bununla birlikte, öğretmenler serbest oyun zamanında öğretmenin alması gereken rol olarak en çok sırasıyla gözlemci, rehber/yönlendirici, izleyici rollerini, en az ise katılımcı rolünü belirtmişlerdir. Bu bulgular ışığında, öğrenme merkezlerinin çocukların ihtiyaç ve ilgilerine göre düzenlenmesi ve esnek ve uyarlanabilir olması, merkezlere 2-4 haftada bir yeni materyallerin eklenmesi, fen ve doğa ve matematik merkezlerine yer verilmesi, doğal çevre ve geri dönüşüm malzemelerinden yararlanılması ve toplumsal cinsiyet kalıpyargılı olmayan oyuncak ve materyallerin teşvik edilmesi önerilebilir.
Çocuktan beklentiler

Tarım toplumundan sanayi toplumuna, sanayi toplumundan bilim toplumuna geçişler gerçekleşmiştir. Bütün bu toplumlarda, çocuklardan beklentiler de değişiklik göstermektedir. Tarım topluluğunda insan emeği kol gücüne dayanır. Bu sebeple çocuklardan beklenti de iş gücünü arttırmaktır. Daha fazla çocuğa sahip olmak, erkek çocuğunu iş gücünü arttırdığı için değerli görmek bu topluluktaki beklentilerin temelini oluşturmuştur. Sanayi toplumunda ise, kol gücünün yerini makine gücü almıştır. Bu toplumda bilgili kişi aile büyüğü değil ustabaşıdır. Bu dönemde çocukluk dönemi fark edilmiştir. Çocuğun ayrı bir gelişimi olduğu araştırılmıştır. Bilgi toplumunda ise, iletişim ve bilgiye ulaşım hiçbir zaman olmadığı kadar hızlıdır. İnternetin yaygınlaşması, Facebook Twitter gibi sosyal ağların kullanılması bu dönemdedir. Bu toplumda ise, aileler kendi kafalarındaki geleceği çocuklarına hazırlama telaşına düşmüşlerdir. Aileler çocuklarını düşündükleri için çocuğun yerine çocuğun hayatı hakkında karar vermiştir. Bu durum çocukların özerklik algısına ve sorumluluk alma özelliklerine olumsuz etki yaptı. Bu durumu değiştirmek için aileler çocuklara oto-kontrol eğitimleri vermeli ve çocukların dürtü kontrolü becerisini geliştirmelidir. Duygularını tanıyıp kararları akıl mantık ve muhakeme yoluyla almaları sağlanmalıdır.
Rethinking curriculum as imagined childhoods
Authors: New Rebecca Staples

This paper proposes a reconceptualization of an early childhood curriculum as an imagined childhood such that children’s early childhood education is linked to, rather than separated from, families and communities.   Drawing on research by psychological anthropologists in cultures as diverse as Italy, Norway, China and Japan, the concept of cultural models is used to explain cultural differences in parenting and early childhood education. Globalization consequences, including changing national goals, dramatic population shifts, and research on immigrant parenting are used to highlight the possibilities of cultural change.   The sort of change envisioned here requires ongoing intentional and inclusive deliberations involving teachers, families and community members who imagine and negotiate better ways to care for and educate their young children.   Examples from the municipal services of Reggio Emilia and other Italian communities are used to highlight the array of possibilities available when adult relationships are prioritized along with those among children. Examples of recent research by Turkish scholars is used to highlight the possibilities of change and collaboration in Turkey.
Akademisyen olmak

Published: April 2018

Genç bir akademisyen olmak uzun bir maratona başlamak gibidir. Yolun başında olan bu akademisyen kendinden yaşça büyük olan akademisyenlerin tecrübelerine gerek duyabilir. Öncelikle akademisyenler puan ve yayın yetiştirmek kaygısıyla intihale başvurmamalıdırlar.   İntihal bir suçtur ve başkasının emeğini hiçe saymaktır. Daha sonra akademisyenler derste sadece not tutturmak için değil öğrencilerini araştırmaya ve konuyu anlayıp yorumlamaya sevk etmelidir. Dersleri yeni yöntemlerle desteklemelidir. Genç olmanın avantajını kullanıp iyi araştırmalar yapmalı ve kendinden sonraki nesle örnek olmalıdır.

Concretización e integración: hacia un análisis fenomenológico-cognitivo de «Continuidad de los parques» de Julio Cortázar
Authors: Pérez Ramírez Carlos Andrés
Published: April 2018

En este artículo exploro la mutua iluminación que hay entre la teoría fenomenológica de R. Ingarden y la teoría cognitiva de B. Dancygier sobre la construcción de sentido de las obras literarias. Desarrollo puntualmente la noción de concretización y hago un análisis del papel de la imaginación en dicho proceso, diferenciando -en términos fenomenológicos- su función en la conceptualización lingüística de su función en la experiencia perceptiva. Después muestro que esa distinción es útil para comprender el proceso de construcción de espacios narrativos. Finalmente, adelanto un análisis del cuento de Julio Cortázar Continuidad de los parques, en donde muestro el valor de la distinción para capturar adecuadamente la estrategia literaria que sigue el cuento

Uncontrolled hypertension leads to complex problems experienced by patient as the complication of the hypertension. The patient’s ability to do self-care (self-care agency) is essential and recommended to control hypertension. Age, sex, education, occupation, marital status, decision making, duration of hypertension, lifestyle, and insurance availability are contributed to the self-care agency. Nurses and patients should be able to know and understand these self-care agency related factors. The aim of this study was to identify self-care agency relating factors of hypertension patients in Pekanbaru. This study conducted using a quantitative approach with cross sectional design and involving 100 hypertension patients who recruited using purposive sampling techniques. Self-care agency was measure using exercise of self-care agency (ESCA) questionnare. Data were analyzed using Spearman test and Chi Square test to determine the relation of each factors on self-care agency and multivariate logistic regression test to determine the most related factors on self-care agency. The result showed that there were a significant different of age (p=0.048), education (p=0.002), gender (p= 0.025), health insurance (p=0.027), and life style (p=0.003) with self-care agency. Meanwhile, there were no signifcant different of occupation (p=1.000), decision making (p=0.800), marital status (p=1.000), and duration of hypertension (p=0.567) with self-care agency. Multivariate analysis revealed that the most influence factor for self-care agency is life style. This study suggest the nurses in improving self-care agency of hypertension patients must concern about patient lifestyle and help patient to modify their lifestyle.

Abstract. Flamboyant [Delonix regia (Boj. ex Hook) Raf.] leaf contains flavonoid compounds that are expected to have immunostimulatory effect. This research was done to determine the effect of flamboyant leaf extract on immune response by accessing the activity of immune cells and capability test the extract as immunostimulant in mice. Leaf extraction was done by maceration using methanol in the Laboratory of Biology of Chemistry Department, Faculty of Mathematics and Natural Sciences of Syiah Kuala University whereas animal treatment and testing were carried out Micro-technique Laboratory of Biology Department of the same faculty. This research used 20 male mice strain Swiss-Webster aged 7-8 weeks were randomly assigned to 4 treatment groups with five replications each. Group 1 (P0) was untreated control; group 1-3 were mice administration flamboyant leaf extract 250 mg/kg BW (P1), 500 mg/kg BW (P2), and 750 mg/kg BW (P3) per oral. The treatments were given for 14 days after one week of adaptation period. Blood samples were collected before and after extract treatment and used for leukocyte count analysis. Phagocytosis activity was accessed by carbon clearance assay on day 15. At the end of the study, all mice were sacrificed for spleen weight analysis. Data obtained was analyzed by Analysis of Variance followed by Tukey test (Leukocyte count and spleen weight) or regression analysis (carbon clearance). The results showed a flamboyant leaf extract administration resulted in increased leukocyte counts that were significantly different (p0.05) between treatment groups.  Phagocytosis test indicated the extract had moderate to strong immunostimulatory effect whereas spleen weight analysis did not show any difference among treatment groups. In conclusion, flamboyant leaf methanol extract was able to increase immune cells and had potential immunostimulatory activity in mice.Keywords: Delonix regia, immunostimulant, leukocytes, lymphocyte proliferation.

Lahat is one of the districts within the province of South Sumatra, the site of research, saving many cultural remains, one of them from the paleolithic period, which for so long received no attention from environmental researchers. This is the basis of the main problems that cover geology in general. Therefore, the purpose of this study is to conduct surface geology mapping in general as an effort to present geological information, while the aim is to know the geomorphological aspects, stratigraphy, geological structures associated with existence in paleolithic sites of research area. The research method begins with literature review, survey, analysis, and interpretation of field data. Environmental observations provide information about the landscape consisting of terrestrial morphology units, weak corrugated morphology units, and strong corrugated morphology units. The rivers are in the Old River, the Adult River, and Periodic /Permanent River. The constituent rocks are Gumai Formation, Benakat Air Formation, Muara Enim Formation, Kasai Formation, and alluvial. The geological structure is a strike slip fault that flows northeast-southeast. The study was conducted on the Kikim River, Lingsing River, and Pangi River, which stretches from east to west with direction from south to north.
