Authors: ERDEN Yavuz , TEKIN Suat , BETUL CEYLAN Kevser , TEKIN Cigdem , KIRBAG Sevda
Published: August 2019

The importance of secondary metabolites obtained from fungi is increasing day by day in terms of human health. Many physiological and pharmacological effects, mainly antimicrobial, anticancer and antioxidant properties of these compounds have been reported. Aim of this study is to determine the anticancer, antioxidant and antimicrobial effects of aspergillin PZ and terphenyllin compounds, which are isolated from Aspergillus and also subjected to limited number of studies. The antimicrobial activity of aspergillin PZ and terphenyllin compounds was determined by using disc diffusion method using different bacteria. The antioxidant property of the compounds was determined by measuring the level of DPPH free radical scavenging. Cytotoxic activity was determined by experiments on human prostate cancer cell lines (PC3 and LNCaP) and over cancer cell line (A2780). Both compounds showed low antimicrobial activity on test bacteria (approximately 2-3 mm zone). High concentrations of applied compounds showed apparent DPPH free radical scavenging activity, while % scavenging activity was quite low at low concentrations. Both compounds showed significant anticancer activity on cancer cell lines (p <0.05). Our results suggest that these two compounds have important biological properties due to their antioxidant and anticancer activities.

Published: August 2019

Today, the amount of biological data types obtained are increasing every day. Among these data types are micro arrays that play an important role in cancer diagnosis. The data analysis that are carried out through traditional approaches have proven unsuccessful in delivering efficient results on data types where data complexity is high and where sampling is low. For this reason, using a hybrid algorithm by merging the effective features of two distinct algorithms will yield effective results. In this study, a classification process was performed firstly by dimension reduction on micro array data that were obtained from the tissues from patients with a tumor in their central nervous system and then by using an artificial neural network algorithm that was optimized through Fire Fly Algorithm (FF), a hybrid approach. The data obtained were compared to K Nearest Neighbors (KNN), Support Vector Machine (SVM) and Artificial Neural Networks (ANN) classification algorithms, which are frequently used in the literature. Also, the results were compared to the findings that were obtained from artificial neural networks, which are reinforced by Genetic Algorithm (GA), another hybrid approach. Then the results were shared. The performance results obtained show that hybrid approaches present a highly precise and more efficient classification process but they show a slower performance than basic classification algorithms.

Authors: CINAR Nihat Cagil , OCALIR Ebru Vesile
Published: August 2019

The damage caused by mining activities are usually environmental aesthetic disturbances (pits and voids), degradation of the existing topographic structure, the pollution of underground and surface water resources, the problems of dust in the living areas, the negativities in terms of life and property safety, the damages of the vital usage areas and the restriction of the living spaces. A methodology has been defined to determine the best future land use alternative for active marble mining sites. GIS, multi-criteria decision making method and fuzzy logic methods are used together to create a land use suitability model as a decision support tool. The study is limited to marble mining activity in the case study of Antalya, Burdur, and Isparta regions (Turkey). The model results give the best option among the alternative land use classes, agricultural areas (A), afforestation (F), recreational area (R), industrial area (I) and landfill area (L) for the 715 marble mines in the study area.

Authors: İZOL Bozan Serhat , ÜNER Devrim Deniz
Published: August 2019

Background: Modified lip repositioning operation (MLR) are being used very
frequently in recent times for treating Gummy Smile (GS) caused by hyperactive
upper lip as they are easily applicable, have very few side effects and high
patient satisfaction. The purpose of this study is to assess whether or not the
effects of MLR operation that is used in GS treatment is temporary. Methods:
In this study, 16 female patients who had complaints of excessive visibility of
their gums while smiling were treated by MLR operations. The amounts of
visibility of the gums were measured before the operation and in the 3rd and
6th months following the operation.Results:
According to the measurements that were made and analysis that was carried out,
the mean amounts of visible gums before the operation, 3 months after the
operation and 6 months after the operation among the 16 patients were
respectively 4.93±0.85 mm, 1.06±0.98 mm and 2.87±0.8 mm. The mean amount of
reduction in the amounts of the visible gums after the operation were respectively
3.75±0.93
mm and 2.06±0.68
mm for the 3rd and 6th months after the operation.

Conclusions: Based on the results of this study, we may state that the effects of
the MLR operation on the amount of visible gums while smiling decrease in time.
However, the fact that the study was carried out on a few patients prevents us
from reaching precise conclusions about this topic. As the authors, we
recommend that similar studies are carried out with larger samples, and for the
purpose of restricting lip movements, Botulinum Toxin is applied 2 weeks before
the operation.

For the caused harvesting loss problem by inaccurate alignment of the semi-feeding peanut harvester, an automatic alignment system on the control core of the single chip microcomputer μPD78F0525 was designed. The system adopts a four-bar detection mechanism to transmit the offset to the controller through the sensor and to adjust the excavator in time. On this basis, a peanut automatic alignment test device is developed, which is composed of conveying platform, ridge ditch, hydraulic execution system, signal detection mechanism, signal processing and control system, etc. The influence effect of the main factors of the system is tested through the test bench. The results show: the reaction time increases with the increase of spring preload and deviation distance, gradually decreases and tends to remain unchanged with the increase of forward speed, and first decreases and then increases with the increase of hydraulic flow. The unqualified rate first decreases and then increases with the increase of spring preload, gradually increases with the increase of forward speed and deviation distance, and gradually decreases with the increase of hydraulic flow. The effectiveness and stability of the automatic alignment system can meet the operation requirements. It effectively solved the problem of automatic alignment of the semi-feeding peanut harvester and provided a technical reference for the research and development of the automatic alignment system for harvesting the fruits under the soil.
Understanding the Critical Aspects of South Asian Labor Market: Implications and Policy Responses
Authors: Ullah Md. Mamin
Published: August 2019

Objectives: This paper attempts to explore the critical insights into the labor markets of South Asian countries taking ILO’s Key Indicators of the Labor Market (KILM) as an example for illustrations. In addition, the paper puts its lens on addressing adequate policies and program responses at country level, especially for Bangladesh.
Methodology: This is basically a policy-focused study focusing on an extensive analysis of existing relevant documents and literature. The paper has therefore adopted three steps methodological approach: collecting, scrutinizing and analyzing. The required data were collected from secondary sources including strategic papers, technical notes, conference proceedings, statistical reports, research articles, relevant books and e-materials of reputed international organizations such as ILO and World Bank.
Findings: A critical review of the existing facts and documents has revealed that despite geo-political and ethnical differences, South Asian labor economies are characterized with homogonous labor market characteristics including low labor force participation rate, gender gap in employment and wages, notable labor dependency ratio, working poor, sluggish wage growth, low labor productivity, excessive working hours, high NEET rate, and a state of labor underutilization. In addition, countries differ in terms of policy issues, implementation levels, data availability and compliance to ILO’s decent work agenda to a large extent.
Recommendations: An integrated labor policy incorporating the lessons and experiences of developed countries, opinions of stakeholders and labor specialists, balanced and diversified development programs, compliance to ILO’s decent work agenda, and collaborative works with national and international labor organizations are supposed to contribute to better functioning of labor markets.
Implications: Although this region of the world is blessed with abundant labor force, a critical analysis has revealed several implications at both national and regional level. The current scenario of lower labor force participation rate and higher time-related underemployment indicate the absence of policies for the fullest utilization of this golden human resource. In addition, slow or negative wage growth and poor wages badly affect the living standards of workers. Despite the consecutive growth in industry and service sector, still the employment in this region is predominantly agricultural which in turn is largely responsible for informal employment.
Value/Originality: This study is one of very few labor market studies focusing on the critical aspects of South Asian labor markets. The paper is therefore expected to add value to the existing field of regional labor market research. Academics, researchers, policymakers and stakeholders are largely be benefited from this study.

Cities have become integral in the quest to achieving universal sustainable development. For example, the United Nations in 2015 as part of the 17 Sustainable Development Goals called for cities and human settlements to be inclusive, safe, resilient and sustainable (Goal 11). This was in line with the 2012 National Urban Policy of Ghana which seeks to promote a sustainable, spatially integrated and orderly development of urban settlements with adequate housing, infra-structure and services, efficient institutions, and a sound living and working environment for all people to support the rapid socioeconomic development of Ghana. Six years into the imple-mentation of the National Urban Policy by the government, what is the sustainability status of the Ghanaian city? The aim of this study was to comprehensively evaluate the sustainability status of Accra Metropolitan Area, the capital city of Ghana. The study adopted a set of city sustainability indicators that revealed the weak and strong points of Accra metropolis. Forty-one Accra Sustainability Indicators were defined and classified into Economic, Environment, Social and Institutional (local governance) dimensions. The evaluation was for a period of 4 years, (2012 to 2015) during which the 2012 Urban Policy and its action plan were being implemented. Ques-tionnaires were developed based on the indicators and administered to stakeholders. The quanti-tative data collected was analyzed using Statistical Package for Social Sciences (SPSS) and Microsoft Excel. The results showed Accra’s economic dimension approaching sustainability while environmental and institutional dimensions performed poorly. The social dimension, thoughperformed below average, rose marginally over the period. Overall sustainability index of Accra was below average and showed a progression towards sustainability over the last 4 years, rising from 0.48 in 2012 to 0.51 in 2015. The findings of this study are helpful to local authorities for sustainable city planning and management.

The River Nile is one of the world’s longest rivers. The Damietta branch in Egypt is important as a major source of irrigation and navigation path from Cairo to the Mediterranean Sea. Morphological changes in this branch of the Nile occurred following construction of the Aswan High Dam, which affected sedimentation and erosive flow, especially at bends in the river. In this study, morphometric temporal changes were investigated for the forced bends using Remote Sensing (RS) and Geographical Information System (GIS) techniques for a study period between 1987 and 2015. In addition, a comparative study was performed among three image classification techniques; onscreen digitizing, maximum likelihood classification and histogram thresholding techniques. A field map of the river banks for the year 2000 was used to verify morphometric behaviorof the forced bends extracted from the satellite images. The study showed that the maximum likelihood classification technique showed good performance in shoreline detection, with percentage error of only 0.42 % compared with observed data. Results show significant morphometric changes of the bank status for the forced bends studied. The forced bend named Sherpas was found to have the highest average annual rate of erosion, with a value of 1.62 m a-1. The maximum average annual rate of sedimentation was located at the inner bank of Sawalem forced bend, with a value of 1.0 m a-1. The maximum erosion and sedimentation rates achieved the greatest values within the period 1987 to 1998.

This research aims to identify the role of natural wetlands in arsenic (As) removal. Phu Lek wetland in Loei Province, Thailand, was selected as the study area. Monthly samples of water (144), plant (360), and sediment (144) were collected from the wetland for 24 months. As concentration in the surface water at the wetland inlet was 0.85±0.26 mg L-1, and 0.02±0.01 mg L-1 at the wetland outlet. It was observed that the As level in water decreased significantly along its flow path, with an As removal efficiency of 98 %. As concentration in the sediment was 89.53-356.22 mg kg-1 at the inlet of wetland, but decreased gradually downstream of the water flow. Three dominant emergent plant species were observed in this wetland. As accumulation (0.02-2.37 mg kg-1) was noted in all the parts of the three plant species. As content was the highest in the rootlet (0.00-1.27 mg kg-1) compared to that in foliage (0.00-0.84 mg kg-1), leaf stalk (0.00-1.86 mg kg-1), and rhizome (0.00-2.64 mg kg-1). The level of As in the different vegetation species was in the order Diplazium esculentum > Colocasia esculenta > Lasia spinose. Further, As entrapment in the different plant plants followed the order rootlet > rhizome > foliage > leaf stalk. All the three plant species showed high bioconcentrationfactors, with values of 0.03-1.28, 0.02-0.93, 0.00-0.84, and 0.00-0.38at the rootlet, rhizome, foliage, and leaf stalk, respectively, but had low translocation factors (foliage/rootlet: 0.02-0.90 and leaf stalk/rootlet: 0.00-0.44). In summary, As present in the surface water could be effectively removed by the wetland system.

This research studied synthesis of calcium oxide from river snail shells by calcination at 700,800 and 900 °C for 4 h, and its subsequent use as a catalyst for biodiesel production. The calciumoxide fraction in calcined river snail shell was analyzed by X-ray fluorescence (XRF), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRF result showed calciumoxide levels of 59.499 %, 70.113 % and 73.88 1%, respectively, at corresponding calcination temperatures of 700, 800 and 900 °C. The SEMimages revealed porous, rough, and fragile surfaces which became agglomerated at elevated temperatures. The calcium oxide obtained from each calcination temperature was utilized as a catalyst in production of biodiesel. The process usedwaste cooking oil and methanol in a molar ratio of 6:1, reaction temperature 60-65 ̊C for 3 h and 1- 3 % by weight of catalysts. The transesterification reaction using calcined river snailshell as catalyst was compared at three temperature ranges. They results revealed that a calcination temperature of 800 ºC, a catalyst amount of 1 % resulted in maximum biodiesel yield, at 95.91 %. The properties of biodiesel, flash point, heat of combustion, acid value and methyl ester contentwere analyzed. The results found biodiesel from this research was qualified according to the standards of the Department of Energy Business. In conclusion, river snail shell is considered effective as a source of calcium oxide catalyst for commercial biodiesel production in the future.

Published: August 2019

The problem of waste is very worrying because it has a direct impact on humans, especially the inclusion of plastic elements in the human body through fish and food exposed to microplastic. One way to overcome the problem of waste is to reduce waste from its source by sorting methods from the source and managed further through the process of recycling or upcycling into new products. Reducing waste from its source by sorting and then saving it in a Waste Bank is one promising breakthrough and can encourage people to actively participate in environmental management. The purpose of this study was to obtain a mapping model of the waste management service area in the city of Manado as needed. The research data was obtained through research on smash applications for waste banks supporting field research through observation and interviews. Data was analyzed by mapping the position of waste banks in the city of Manado. Furthermore, comparing the three garbage banks in Manado city to find a pattern of waste bank management with various indicators. The results of the study indicate that the current mapping of the position of waste banks in Manado consists of the center, the suburbs and outside the city. Furthermore, the results of the comparison of the three garbage banks conclude that the most effective waste bank is a waste bank in a residential area. An effective waste bank is one of the strategies for implementing 3R (Reuse, Reduce, Recycle) in waste management at its source at the community level. The implementation of the waste bank in principle is a social engineering to invite the public to sort out waste for environmental sustainability and public welfare.

The Coast Area is an area that has a physical condition where erosion occurs at other times, sedimentation occurs. Both of these conditions can be a problem in coastal areas. This is very closely related to land use in coastal areas. Another problem is that in protecting the beach by the government it is very expensive and cannot be carried out simultaneously throughout the coastal areas, so that people have to wait in uncertain times.In North Sulawesi coastal areas are widely used as settlements, tourist areas and other public facilities. The community has its own ability both in terms of the availability of natural resources and labour, so that it can secure the coast to reduce the risk of damage in its coastal areas.The method of building of non-structural coastal protection can be carried out by people whose construction types can be combined according to the conditions and availability of natural resources in the area.

Published: August 2019

A pesquisa é resultado do trabalho de conclusão de curso de Érick Scopel, sob orientação dos professores Nicolau Matiel Lunardi Diehl e Rodrigo Sychocki da Silva. O trabalho teve por objetivo apresentar uma caracterização geométrica de operadores lineares de R² e R³. Através da Teoria de Jordan aplicada a matrizes associadas aos operadores, pode-se caracterizar as transformações lineares, observando as matrizes quadradas de ordem dois, quando o operador fosse em R², e quadradas de ordem três quando fosse em R³. A partir de Bueno (2006) e Lima (2012) foi obtida uma matriz de Jordan que pudesse ser equivalente à matriz associada ao operador possibilitando assim inferir como o operador influenciava determinadas regiões do plano ou do espaço. A partir da teoria escreveram-se os operadores lineares de um modo que tornasse possível organizá-los em classes. Além disso, mostrou-se no trabalho que os operadores lineares têm diversas aplicações práticas, tais como: Estudo de Fractais, Deformações, Morfismos e Computação Gráfica. Na Computação Gráfica, por exemplo, a teoria dos operadores lineares é utilizada na manipulação de imagens que envolvem rotações, cisalhamentos, dilatação e compressão, alteração de cores, que são todos exemplos de transformações lineares. Através de uma proposta metodológica de acordo com Gil (2010), fundamentada na pesquisa bibliográfica, mostra-se no trabalho que os operadores lineares de R² e R³ atuam como dilatações, compressões, cisalhamentos e rotações, quando se observa os vetores na base de Jordan.

Published: August 2019

A presente pesquisa é resultado do trabalho de conclusão de curso de Marina Pacheco, sob orientação da professora Dra. Greice Andreis, no Curso de Licenciatura em Matemática do IFRS, Campus Caxias do Sul. Esta pesquisa teve como objetivo conhecer algumas das possíveis causas associadas às dificuldades de aprendizagem em Matemática. A partir de uma pesquisa de campo, realizada por meio de questionários a estudantes concluintes do ensino médio regular da rede pública estadual de ensino de Caxias do Sul, e seus professores de Matemática, buscou-se identificar por que a Matemática é um dos componentes curriculares em que os estudantes apresentam maior dificuldade, e como estas dificuldades podem ser superadas, mediante o conhecimento de suas causas. A partir da literatura, identificaram-se algumas das causas como a capacitação dos professores que atuam nas séries iniciais (FIORENTINI, 2008), a influência da família (BRUM, 2013) e as metodologias adotadas pelos professores (CUNHA, 2009; D’AMBROSIO, 2011). Com a pesquisa de campo evidenciou-se que as dificuldades ainda podem estar relacionadas à falta de compreensão e interpretação, ao aprendizado superficial e a problemas de concentração. A partir das causas das dificuldades de aprendizagem em Matemática encontradas, apresentam-se alguns pontos a serem observados pelos professores: formação continuada, reflexão sobre sua prática docente, conexões entre conteúdos matemáticos e cotidiano, conhecimento sobre a realidade do estudante, interesse e motivação pela Matemática e metodologias de ensino. Conhecer as causas das dificuldades de aprendizagem é fundamental para a intervenção do professor no processo de ensino e de aprendizagem da Matemática.
