Promoting a sustainable traditional technique of aquifer water acquisition common to arid lands: a case study of Ghassem Abad Qanat in Yazd Province (Iran)
Authors: Megdiche-Kharrat Fairouz , Ragala Rachid , Moussa Mohamed
Published: May 2018

Qanats are a traditional technique used for aquifer water acquisition and irrigation in dry lands, common to the Middle East. They provide fresh water to communities of users by draining groundwater from aquifers. In Iran, authorities are reporting about 37,000 active qanats contributing about 11% of the country's total groundwater supply. Yazd Province, located in the central part of Iran's plateau, is among the driest regions of the country with more than one million people. It counts 3,193 known qanats with an annual discharge estimated today at about 350 million m3. Ghassem Abad qanat irrigates the agricultural lands of Ghassem Abad village in the Province of Yazd. Its water is managed by an administration headed by a mirab. This paper describes the qanat's mechanism and provides an overview about qanats in Iran. It also promotes, through the study of Ghassem Abad qanat, the related water management system as an example of eco-friendly traditional knowledge leading to social equity and sustainability. It explains how water is distributed to stakeholders (through water shares and irrigation cycles). Nevertheless, and for its survival, the qanat of Ghassem Abad has to continuously deal with social and economic challenges. The farmlands are continuously menaced by urban expansion.
Avaliação do impacto do marco regulatório vigente na matriz de correlação dos indicadores-chave de risco em concessionárias de geração
Authors: PIACENTINI Otavio , MASTELLA Mauro
Published: May 2018

Esta pesquisa aborda uma avaliação do impacto do marco regulatório vigente para a matriz de correlação dos Key Risk Indicators (KRIs) de empresas concessionárias de geração de energia. Foi realizada uma compilação de referencial teórico relativo ao marco regulatório vigente ao qual o setor elétrico está submetido e a avaliação e identificação dos diferentes riscos do negócio, bem como a sua composição por meio de matrizes de correlação. Posteriormente, foi realizado um levantamento de dados relativos ao período de 2010 a 2015 em uma concessionária do setor elétrico, para a construção das matrizes compostas pelos indicadores sugeridos, bem como uma análise da amostra em dois subperíodos (entre 2010-2012 e 2013-2015) para mensuração da mudança do perfil de cada uma das matrizes de correlação a partir do novo marco regulatório. Por fim, foi analisada a relevância entre os resultados obtidos na correlação de cada par dos KRIs e seu embasamento com o referencial teórico apresentado, resultando em uma avaliação sobre o impacto do novo marco regulatório na matriz de correlação dos KRIs em uma concessionária do setor elétrico, objeto da análise do trabalho. Os resultados indicam que para as condições de contorno estabelecidas, não é possível afirmar, com significância estatística, que o marco regulatório vigente teve impacto, de maneira generalizada, na composição da matriz de correlação dos KRIs utilizados nesse trabalho, mas sim, que há indícios de impacto em alguns desses KRIs individualmente.
Autonomia universitária e políticas públicas: uma análise sobre a atuação das instituições públicas de ensino superior do Estado do RS
Authors: SANTOS Emir , BEROLDT Leonardo
Published: May 2018

Este artigo buscou identificar em que medida a autonomia universitária das instituições públicas do Rio Grande do Sul dialogam entre si. Além disso, buscou-se ainda identificar se as políticas públicas harmonizam a atuação destas instituições, visando a plenitude de seu papel social. Para isto, realizou-se uma pesquisa bibliográfica. Primeiramente aborda-se um histórico do ensino superior e das políticas públicas. Posteriormente, realiza-se sobre a influência das políticas públicas voltadas para as instituições públicas de ensino superior no estado do Rio Grande do Sul anos 2000, período esse no qual ocorreu uma forte política pública expansionista de oferta de ensino superior público. Esse trabalho visa verificar a relação entre autonomia universitária e políticas públicas e confrontar estas informações com a realidade no processo de tomada de decisão das instituições, de forma a fomentar a discussão sobre a eficácia da autonomia, tentando analisar se a metodologia do processo de decisão está realmente voltada ao exercício do papel social das universidades. Dentre os levantamentos realizados, foi possível identificar a existência de um diálogo entre universidades federais, entre universidades federais e institutos federais, entre universidades estaduais e comunitárias, mas pouco foi perceptível de diálogo entre entes (União e Estado). Possivelmente este ponto tenha sido o maior exemplo de falta de harmonia entre instituições, carecidas de uma política pública que lhes desse a regência. Devido a isto, não foi possível identificar uma atuação que maximize as potencialidades das instituições.

Synthesis of Lignin-Based Polyurethanes: A Mini-Review
Authors: Gouveia Júlia Rocha , da Costa Cleber Lucius , Tavares Lara Basílio , dos Santos Demetrio Jackson
Published: May 2018

Lignin is a natural polymer composed primarily of phenylpropanoid structures with an abundance
of reactive groups: aliphatic and aromatic hydroxyls, phenols, and carbonyls. Considering the
large quantity of hydroxyl groups, lignin has significant potential as a replacement for petroleum-based
polyols in polyurethane (PU) synthesis and as a value-added, renewable raw material for this purpose.
Several methods of lignin-based polyurethane synthesis are reviewed in this paper for reactive and
thermoplastic systems: direct lignin incorporation, chemical lignin modification and depolymerization.
Despite the unmodified lignin low reactivity towards diisocyanates, its direct incorporation as polyol
generates highly brittle PUs, but with proper performance when applied as adhesive for wood. PU brittleness
can be reduced employing polyols obtained from lignin/chain extender blends, in which glass
transition temperature (Tg), mechanical properties and PU homogeneity are strongly affected by lignin
content. The potential applications of lignin can be enhanced by lignin chemical modifications, including
oxyalkylation and depolymerization, improving polyurethanes properties. Another PU category, lignin-
based thermoplastic polyurethane (LTPU) synthesis, emerges as a sustainable alternative and is also
presented in this work.
Galanthum nivalis Extract is Neurologically Active and Improves Anxiety and Social Interactions in Mesocricetus auratus
Authors: Kip Heather A. , Kuro Maya , Hami Steven , Nugget Terry , Montre Evan R.
Published: May 2018

Background:

Galanthum nivalis has been used throughout history for its medicinal properties.
Although traditionally used as an antidote to poison, G. nivalis has also recently been found
to have effects in neurological conditions such as Alzheimer’s Disease and mild cognitive impairment.
Recent studies also suggest that it may have neurological activity that may be beneficial for
psychiatric and neurological disorders like anxiety.

Objective: This study aimed to assess the neurological activity of G. nivalis extract using a behavioral
test of anxiety-like behavior in Syrian hamsters.

Methods:

G. nivalis extract was administered daily to hamsters while undergoing a semi-naturalistic
version of the open field test to assess anxiety. Hamsters were video recorded during their natural
active times beginning an hour before and ending an hour after lights-on and lights-off. Free roaming
behaviors were scored in a 2 x 4 m open pen with enrichment objects for hamsters to interact
with. After 10 days, hamsters were subjected to a social interaction test with a novel conspecific.

Results:

Hamsters receiving G. nivalis extract showed increased time that was spent free-roaming
and a greater proportion of that time was spent moving. They also spent more time interacting with
enrichment objects in the open pen. The social interaction test showed that hamsters receiving G.
nivalis extract spent more time playing with a novel conspecific.

Conclusion:

G. nivalis extract is a neurologically active natural product with behaviorally relevant
effects. It improved anxiety-like behavior in hamsters, as evidenced by increased time free roaming,
moving, and interacting with objects, while improving social interactions.

Authors: Sharma Jeetu , Jha Manish K. , Bhattacharya Partha P.
Published: May 2018

Background:

This paper proposes a novel MultiChannel Caucus based Medium Access Control
(MC2-MAC) protocol to diminish collisions between different data packets to reduce energy dissipation
of nodes and latency of data packets transmitted by the sensors communicating in Line of Sight
(LOS) communication deployed to supervise distinct raucous provinces in the smart grid.

Methods:

The performance diminishing major problems such as wastage of battery power, bottlenecks
and collisions need to be mitigated to elongate lifespan and to diminish data latency. The employment
of caucus based efficient scheduling scheme enhances synchronization and multiple channels prevent
collisions by reducing the number of contending nodes. The utilization of multiple channels enables
sink node to communicate simultaneously with numerous nodes.

Results:

The influence of multichannel is evaluated by comparing the simulation results of the networks
implementing ZigBee, C-MAC and MC2-MAC protocols. QualNet 6.1 simulator is used to perform the
simulations.

Conclusion:

The work resolute to evaluate and correlate the impact of the multichannel scheme to optimize
the performance metrics of sensors deployed in distinct raucous provinces communicating in
LOS environs in the smart grid and to gain the attention of scholars in this emerging field of research.
Is Attitude an Impediment to Achieving English Proficiency amongst the Final Year Students in the Northern Geopolitical Zone of Nigeria: A Comparative Study of Southern and Northern Geopolitical Zones
Authors: Taiwo Famogbiyele O.
Published: May 2018

This study investigated whether it is the learners’ attitudes in the northern geopolitical zone of Nigeria which impede them from achieving high level of proficiency in the study of English language as compared to that of their counterparts in the southern geopolitical zone. Three research questions were generated to guide the study. 28-item questionnaire adapted from Gardner’s (1985b) Attitude Motivation Test Battery (AMTB) were used to elicit the data needed. The descriptive survey research design that was adopted for the study comprised of four-part Likert-type statements. 610 students (male and female) registered for SSCE examination were selected from 18 government-owned public secondary schools in the Northern and Southern geopolitical zones using stratified random sampling technique. The data collected were analyzed using simple mean scores and percentages. The result of the study showed that students in the Northern geopolitical zones, in fact, have high positive attitude towards the learning of English but were not motivated to learn it and that language anxiety had a pervasive impact on the language learning experience of the students. The study recommends amongst others that, language teachers need to evolve effective teaching and learning strategies that generate the attitudes and motivation most conducive to the production of more successful learners of English language.
Consumption of Electrical Energy in Water Supply and Wastewater Systems in Brazil
Authors: Soares Renan Barroso , Gonçalves Ricardo Franci
Published: May 2018

Traditional processes adopted in water supply and wastewater systems consume large amounts of energy and generate relevant environmental impacts, since energy use is considered one of the largest anthropogenic sources of greenhouse gases. The industry consumes 7% of all energy produced in the world, increasing the costs of operations that cannot be fully passed on to users, especially in developing countries such as Brazil. The worldwide projection of rising electricity prices further aggravates the situation, motivating a mapping of the energy efficiency of the sector in order to identify points of improvement. Several articles on the topic have already been published, but information for Brazil is scarce. This paper presents a review on the energy consumption in each stage of the water and wastewater sector, including the Brazilian scenario. Searches on the site www.sciencedirect.com, using as keywords wastewater, water, energy, consumption and Brazil and government websites resulted in 20 documents that compose this work. The objective of this work was to review the energy consumption in collective water supply and wastewater systems, from raw water abstraction to the final disposal of the treated sewage, by compiling information and adding data on the Brazilian scenario. In general, the current system is inefficient and require political integration in water and energy in order to overcome the challenges.

Published: May 2018

Artikkelissa kuvataan naisyrittäjien työhyvinvointia ja sen yhteyksiä työhyvinvointia ja liiketoimintaa tukevien palvelujen käyttöön. Tukipalveluina tarkastellaan työterveyshuolto- ja kuntoutuspalveluita sekä Elinkeino-, liikenne- ja ympäristökeskuksen (ELY) tarjoamia koulutusrahoitus-, konsultointi- ja neuvontapalveluita. Tutkimusaineisto (n=128) kerättiin sähköisellä kyselyllä vuosina 2010–2011 naisyrittäjien työhyvinvoinnin ja liiketoimintaosaamisen sekä yrittäjien sijaisjärjestelmän kehittämishankkeessa Keski-Suomessa. Naisyrittäjien työhyvinvointia kuvaavien muuttujien ja tukipalveluiden käytön välisiä yhteyksiä ja niiden tilastollista merkitsevyyttä tarkasteltiin ristiintaulukoimalla ja Fisherin tarkalla testillä.  Naisyrittäjät (84 %) olivat omistautuneita työlleen ja tarmokkaita työssään. Heitä kuormitti yleisimmin työn epävarmuus sekä työn keskeytykset ja kiire. Työnantajayrittäjät kokivat stressiä enemmän kuin yksinyrittäjät (p = 0,039). Työterveyshuoltopalvelujen kattavuus oli heikko erityisesti yksinyrittäjien (13 %) keskuudessa, ja kuntoutuspalveluja oli käyttänyt harva naisyrittäjä (11 %). ELY-keskuksen neuvonta- ja yrittäjien koulutuspalvelujen käyttö oli sen sijaan melko yleistä (44 %). Naisyrittäjien psykososiaalisista kuormitustekijöistä työn keskeytyksillä ja kiireellä oli yhteys yrityskohtaistenkonsultointipalvelujen käyttöön (p = 0,024). Työn keskeytyksistä ja kiireestä kärsivät yksinyrittäjät olivat muita yleisemmin työterveyshuoltopalvelujen piirissä (p = 0,029). Työntekijöiden poissaoloista kuormittuneet työnantajayrittäjät olivat järjestäneet muita useammin työterveyshuoltopalvelut työntekijöilleen (p = 0,001). Tutkimuksen tulokset kertovat työterveyshuollon kapeasta roolista naisyrittäjien työhyvinvoinnin tukijana. Työterveyshuollon laajempi hyödyntäminen edellyttää palvelujen saatavuuden, hankinnan ja korvattavuuden kehittämistä. Jatkotutkimusta tarvitaan liiketoimintaa tukevien, yrityskohtaisten palvelujen merkityksestä naisyrittäjien työhyvinvoinnille.
Nainen perheväkivallan tekijänä – ryhmäinterventio väkivaltakäyttäytymisen loppumiseksi
Authors: Keiski Pia , Helminen Mika , Lindroos Maria , Kommeri Hanna , Paavilainen Eija
Published: May 2018

Tutkimuksessa kuvataan omaan perheväkivaltakäyttäytymiseensä vapaaehtoisesti apua hakeneiden naisten perheväkivaltakäyttäytymistä, aiemman väkivaltakäyttäytymisen kohteena olemista sekä niiden yhteyttä toisiinsa ja perheväkivaltakäyttäytymisen yhteyttä itsetuntemukseen ryhmäintervention aikana. Tutkimuksen kohteena olevan ryhmäintervention tavoitteena on naisten perheväkivaltakäyttäytymisen loppuminen. Tutkittavat naiset osallistuivat 15 viikkoa kestävään terapeuttiseen ryhmäinterventioon. He täyttivät osana työskentelyä väkivaltakäyttäytymistä ja -kokemista sekä itsetuntemusta mittaavan kyselylomakkeen ryhmäintervention alussa (N=134) ja lopussa (N=128). Naisista 70 prosentilla oli korkeakoulututkinto, eikä kenelläkään ollut akuuttia mielenterveys- tai päihdeongelmaa. Aineisto analysoitiin kvantitatiivisin menetelmin.Tutkimustulosten mukaan vastaajista väkivaltaa lasta kohtaan oli käyttänyt yli puolet ja kumppania kohtaan noin kaksi kolmasosaa vastaajista. Lapsuudessa vastaajat olivat kokeneet fyysistä (81 %) tai emotionaalista (89 %) väkivaltaa tai nähneet väkivaltaa (83 %). Aikuisuudessa he olivat kokeneet emotionaalista (81 %) ja fyysistä väkivaltaa (67 %). Lapsuudessa nähdyn väkivallan ja aikuisuudessa koetun väkivallan välillä oli yhteys omaan väkivaltakäyttäytymiseen kumppania ja itseä kohtaan. Ryhmäintervention aikana riittämättömyys sekä ahdistus ja pelko vähenivät merkittävästi erityisesti naisilla, jotka käyttivät emotionaalista väkivaltaa kumppania kohtaan, ja äitiyden kokemus koheni merkittävästi niiden naisten joukossa, jotka käyttivät emotionaalista väkivaltaa lasta kohtaan. Tämän tutkimuksen tulosten perusteella voidaan sanoa, että perheväkivaltaa käyttävä nainen on kokenut lapsuudessa ja aikuisuudessa väkivaltaa jane ovat yhteydessä omaan perheväkivaltakäyttäytymiseen. Ryhmäinterventio auttaa etenkin emotionaalista väkivaltaa käyttävien naisten itsetuntemuksen kehittymistä, joka voi mahdollistaa perheväkivaltakäyttäytymisen loppumisen.

Published: May 2018

Este trabajo analiza cómo el funcionamiento democrático y la metodología basada en proyectos (ABP) influyen en el rendimiento del alumnado. Se relacionan las evidencias descritas en la literatura científica sobre la mejora del rendimiento y la inclusión con los resultados logrados por el alumnado de Antzuola en las pruebas de diagnóstico realizadas por el Instituto Vasco de Investigación Educativa. La perspectiva metodológica desde la cual se afronta el estudio es cuantitativa; se comparan los resultados de los años 2010, 2011 y 2013 del alumnado de Antzuola con el alumnado de la Comunidad Autónoma Vasca –que realizaron las mismas pruebas en diferentes centros y estratos lingüísticos. El estudio concluye que las prácticas educativas desarrolladas en el centro generan mejores resultados académicos, mostrando un porcentaje significativamente menor de alumnos con resultados por debajo de la media, lo que puede ser entendido como un mayor nivel de inclusión.
Recordando a Freire en época de cambios: concientización y educación
Authors: Pallarès Piquer Marc
Published: May 2018

El objetivo del artículo es analizar la contradicción de las investigaciones que, al reclamar cambios en educación, determinan un supuesto realismo de la práctica como origen de un cambio al que, paradójicamente, los propios objetos de la escuela terminan acreditando; las demandas de cambio se convierten, en consecuencia, en meras reproducciones de variaciones de lo que ya existía. La metodología utilizada es la revisión hermenéutica de Paulo Freire; proponemos integrar en el binomio teoría-práctica su concepto de concientización, es decir, el proceso mediante el cual las personas somos animadas a explorar nuestra realidad y conciencia. El resultado es que la concientización resulta ser un proceso de acción cultural mediante el cual podemos recuperar la realidad de nuestra situación sociocultural, a través del cual avanzamos más allá de las limitaciones de los cambios educativos y que nos permite también afirmarnos como sujetos conscientes y co-creadores de nuestro futuro.

New Bio-Scientific Interpretations of the Eco-Economic Zootehnization of the Romanian Performing Agriculture
Authors: Străteanu Amalia-Gianina , Stan Simona Nicoleta
Published: May 2018

It is known that in all Western European countries, during the 20th century was initiated, developed, applied and consolidated the bio-scientific principle of agriculture zootehnization, so this trend continues in the first two decades of the 21st century. Based of the official data of EUROSTAT, this article presents the concrete situation of the dynamics of the two main livestock productions, respectively milk and meat, using annual data, namely those published in 2016 and 2017. The authors use new bio-scientific arguments to analyze and interpret the concept of agriculture zootehnization, with unprecedented and documented ighlighting of polyvalent and synergistic aspects, between the effective zootechnical practice of the performing agriculture (on the one hand) and the bioeconomic management of animal husbandry (on the other hand). Thus, the authors report the fact that at 21 611 thousand head dairy cows in the EU (excluding the United Kingdom), is collected a production of 138 511 thousand tonnes milk, with a average milk production of 6 409.29 kg / head, of which in the milk industry (Table 3. with those 14 selected countries), the year is obtained, in thousand tons, 30 087 dairy products (milk for consumption, milk powder, butter and cheese). In the same sense, the authors present and analyze the dynamics of meat production from the farm livestock and they find that the annual values for carcass weight in thousands tons are for bovine 6,885, for pigs 22,522 and for sheep 423, which highlights a real zootechnical, genetic and bio-productive potential. We underline that in two synthesis tables, the authors present the numerical situation of the relations between the European Union and Romania, so in a professional way, through a new bio-scientific argument it is justifiably demonstrated that Romania needs to develop inter-, multi-and transdisciplinary and to apply a real country project for the Carpatho-Danubiano-Pontic autochthon space in its European context.
Health literacy of students. Results of an online survey at the Bochum health university (Germany) / Gesundheitskompetenz Studierender – Ergebnisse einer Online-Befragung an der Hochschule für Gesundheit Bochum
Authors: Reick Sibylle , Hering Thomas
Published: May 2018

Background

Health literacy is of growing importance in public health research in Germany. People with good health literacy are likely to make better health decisions. A large proportion of the German population, not just vulnerable groups, has a problematic or insufficient health literacy.

Aims

The study describes the health literacy of students at a German health university. It investigates the influence of sociodemographic and course-related factors on health literacy. The results are compared with those of the general population from Germany.

Methodology

Study participants were recruited by email. 203 students took part in the online survey (response rate 20.2%). From the European Health Literacy Questionaire 16 (HLS-EU-Q16) 127 datasets of students were completely available and were analyzed in this study. In addition to health literacy, sociodemographic and course-related factors were ascertained.

Results

39 (30.7%) of the students have a sufficient or excellent health literacy. On average, health literacy is lower in the group of students of health-related courses (M=30.6) than in the normal German population (M=34.5). The levels are particularly low in the dimensions of appraising and applying of health information.

Conclusion

The results must be interpreted with care. They can be used as a base for long-term monitoring of students’ health literacy and provide starting points for health promotion within the academic setting. Students of health-related degree should be encouraged to reflect on their own and others health literacy, as this is important for their future work with patients or clients.
Studies on Improvement of Performance of Compression Ignition Engine Fuelled with Mixture of Honge Biodiesel and Tire Pyrolysis Oil
Authors: Kapilan Natesan , Jullya Naik
Published: May 2018

The biodiesel has lower volatility and is costlier than the fossil diesel. Hence it is necessary to add a low cost fuel which has higher volatility, with the diesel. The tire pyrolysis oil (TPO) produced from waste tire and tubes have these desirable properties and hence in this work, we have mixed TPO with biodiesel to enhance the properties of the biodiesel. The engine tests were carried out on a single cylinder compression ignition engine with the mixture of biodiesel and TPO as fuel. From the engine tests, it is observed that the fuel mixture results in engine performance close to diesel operation at the higher injector nozzle opening pressure.

The high-strength steels and tailor welded blanks (TWB) are applied in construction of cars parts to reduction of cars weight [1, 2]. The application of these materials brings possible complicatons during the forming when it proves the considerable influence of stress-strain characteristics differences of of the individual parts of TWB what result in non-constant material flow and consequently a negative movement of the weld interface [3, 4]. One of the ways of elimination of this negative effect is to choose a suitable blankholder system with optimal distribution of blankholder forces by using elastic blankholder with adjustable distribution of blankholder forces. Within the bounds of study the experimental blankholder system with elastic blankholder with adjustable distribution of blankholder forces was used [5, 6]. Finite element methods (FEM) simulation has unsubstitutable role n the study of formability of TWB whereby it is possible to determine the values and points of application of the blankholder forces [7, 8]. The FEM simulations results carried out in simulative LS-Dyna software are presented in this article which is focused on achieving weld interface movement minimalization of tailor welded blanks from DP600 and BH220 materials by optimization of blankholder forces [9, 10].

Telah dilakukan identifikasi anomali sinyal geomagnetik frekuensi rendah sebagai prekursor gempa bumi dengan magnitudo kecil di wilayah Kepulauan Nias. Pada penelitian ini digunakan data gempa dari bulan September 2016 hingga bulan Juni 2017 dengan rentang waktu data geomagnetik yang digunakan 30 hari sebelum terjadinya gempa bumi. Data geomagnetik ini adalah data yang terekam oleh sensor Magnetic Acquisition Data System (MAGDAS). Penyeleksian data gempa bumi dilakukan dengan menerapkan persamaan radius daerah persiapan gempa yaitu Â Pengolahan data geomagnetik dilakukan dengan menggunakan metode Power Spectrum Density (PSD) untuk menganalisis rasio komponen SZ/SH medan magnet bumi dan menggunakan metode Single Station Transfer Function (SSTF) untuk menentukan arah azimuth yang dihasilkan oleh anomali Ultra Low Frequency (ULF).Â  Selanjutnya, untuk memastikan sumber anomali digunakan validasi indeks Disturbance Storm Time (DST). Dari hasil pengamatan diperoleh 3 kejadian gempa bumi dengan anomali ULF sebelum terjadinya gempa. Gempa bumi tersebut adalah gempa 13 Oktober 2016 dengan magnitudo 3,3, gempa 16 November 2016 dengan magnitudo 3,6 dan gempa 16 April 2017 dengan magnitudo 3,2. Lead time anomali ULF untuk ketiga gempa ini memiliki durasi yang lebih pendek dibandingkan dengan lead time anomali ULF untuk gempa bumi dengan magnitudo besar yang pernah terjadi di Pulau Sumatera.Kata kunci: sinyal geomagnetik, ultra low frequency, prekursor, gempa magnitudo kecil, kepulauan nias
