O objetivo deste trabalho foi avaliar as propriedades físicas e mecânicas de chapas de madeira aglomerada utilizando partículas oriundas de maravalhas a três teores de adesivo fenol-formaldeído, 6, 9 e 12% (base massa seca). Os painéis foram produzidos com densidade nominal de 0,70 g.cm-3, ciclo de prensagem com temperatura de 160 °C, pressão de 3,92 MPa e tempo de 8 minutos. Foram avaliadas as propriedades de absorção de água (AA), inchamento em espessura (IE), ambas após 2 e 24 horas, densidade aparente, razão de compactação, tração perpendicular, módulo de elasticidade (MOE) e módulo de ruptura (MOR) na flexão estática e resistência ao arranchamento de parafuso. Os resultados dos testes indicaram que com o aumento do teor de adesivo de 6 para 12%, não houve diferença estatística significativa para os valores médios de densidade aparente e razão de compactação, sendo eles 0,624 g.cm-3 e 1,234, respectivamente, e diminui-se a AA e o IE após 2 e 24 horas. Houve um ganho de 49% para MOR e 40% para MOE. Para tração perpendicular, os maiores valores médios foram referentes ao painel com 12% de adesivo. Já para arrancamento de parafuso, os painéis não atenderam às normas vigentes.

Published: January 2021

Para viabilizar a conservação dos remanescentes florestais em área urbanas, torna-se necessária a busca por ferramentas para o exame de padrões espaciais. Com isso, este trabalho objetivou modelar e correlacionar os padrões espaciais da diversidade arbórea e de grupos sucessionais ao longo de um inventário contínuo em um remanescente urbano de Floresta Ombrófila Mista. Os dados foram obtidos em uma área de 15,24 ha composta por 69 unidades amostrais de 50 m x 50 m, onde os indivíduos arbóreos com diâmetro a 1,3 m do solo igual ou superior a 10 cm foram mensurados e georreferenciados. Os índices de Shannon, Simpson e Pielou, bem como as áreas basais dos grupos sucessionais pioneiras, secundárias iniciais e tardias e climácicas, foram calculados em cada unidade amostral. Semivariogramas foram ajustados para descrever o comportamento espacial das variáveis, sendo, em seguida, interpolados por krigagem ordinária para confecção de mapas temáticos. A cokrigagem foi realizada a partir das variáveis que obtiveram a dependência espacial modelável com geoestatística. A estrutura da Floresta Ombrófila Mista apresentou dependência espacial para os índices de Shannon e Simpson e para os grupos sucessionais. Os mapas indicaram forte influência antrópica, com menor diversidade arbórea nas bordas do remanescente florestal. A cokrigagem mostra que, aumentando a área basal, a diversidade de espécies também aumenta. Os grupos sucessionais apresentaram efeitos significativos nos padrões espaciais de diversidade, em que os grupos tardios e climácicos mostraram os efeitos mais evidentes. Portanto, a maior cobertura por esses grupos sucessionais conduz ao aumento da diversidade arbórea.
Ortolan Bunting Emberiza hortulana at Kvismaren, central Sweden – breeding studies and suggested management
Authors: Sondell Jan , Brookes Craig , Persson Magnus
Published: January 2021

The only remaining Ortolan Buntings in the province of Närke are about 15 singing males in the Kvismaren valley. We studied this small population intensively during May–June, 2011. We found that the birds depend on bare soil of two kinds: potato fields turning green only in early July and open ground underneath birch and elder vegetation in an old bog. Thus spring sowing may be a “trap” as fields that look optimal when the Ortolans arrive in early May will in a few weeks turn green and become less suitable for breeding. In 2011, 6 pairs likely raised young and this result seems normal. Possibly this very small population persists due to recruitment from the much larger population in northern Sweden, that passes through Kvismaren during spring and autumn migration. The central Swedish population is only about 100 pairs and will probably disappear if a management plan is not implemented rapidly. New potentially suitable areas must be identified, and optimal breeding conditions must be provided at sites where Ortolan Buntings still occur.

Are we measuring natural resource wealth correctly? A reconceptualization of natural resource value in the era of climate change
Authors: Lebdioui Amir
Published: January 2021

Underlying the management of revenues from natural resource extraction is a set of assumptions about how abundant and how valuable these resources are. Nevertheless, existing approaches to measuring the value of extractive resources are seriously flawed. This paper proposes two avenues for improving them. It explains how a multidimensional approach to measuring resource wealth can be used to identify the policy challenges that a country might face as it sets out its strategy for managing extractive revenues. It also provides a rethinking of the valuation of extractive wealth by integrating environmental considerations. Extractive activities can at times incur a great loss of (renewable) opportunity income, either directly or indirectly, because of their environmental impact. By analysing a range of examples from across the globe, this paper extracts key lessons on the true value of extractives and why it matters for policy makers, civil society, and international donors today.
Os nomes nus em caboverdiano
Authors: Miranda Wânia
Published: January 2021

No presente artigo trataremos das características gerais do sintagma nominal do caboverdiano. Exploraremos a questão dos nomes nus, em uma perspectiva semântica, observando uma das estratégias de expressão de genericidade na língua, bem como as interpretações definida e indefinida dos nomes nus. A nomenclatura nomes nus é utilizada neste trabalho para se referir aos nomes sem a presença de determinantes. Essa denominação serve à literatura para contrapor nomes com a presença de determinantes a nomes sem essa presença, considerando que os primeiros sejam a forma mais usual nas línguas em geral. Defendemos que, pelo menos em caboverdiano, os nomes nus seriam a forma padrão na língua. A presença de determinantes, por outro lado, é guiada por estratégias específicas. A partir de dados coletados em trabalho de campo na ilha de Santiago e dados retirados de trabalhos prévios sobre a língua, apresentaremos as características gerais dos nomes nus do caboverdiano, na variedade de Sotavento. Partindo do fato de que os nomes em caboverdiano, em sua maioria, não precisam ser acompanhados de determinantes, veremos que as noções de pressuposição e unicidade serão relevantes dentro do sintagma nominal da língua e podem favorecer determinadas leituras ou interpretações do nome nu em detrimento de outras.
Léxico e identidades culturais: análise da toponímia indígena de natureza antropocultural no sertão de Quixeramobim
Authors: Gonçalves Elis Larisse Santos , Ximenes Expedito Eloísio
Published: January 2021

Nomear é uma das primeiras atitudes humanas diante do mundo que nos cerca, tendo em vista que a linguagem atravessa a própria existência humana. Por meio da língua também organizamos nossa maneira de estar no mundo e de atuar sobre ele, o que nos faz pensar a língua como um componente da cultura, se esta é entendida de forma abrangente como sendo “todo um modo de vida” (WILLIAMS, 2015, p. 10). Por meio da língua podemos também compreender as práticas culturais e históricas de nossos antecessores, uma vez que práticas linguísticas que foram usuais em tempos que nos precederam também permeiam as relações sociais do presente, muitas modificadas em suas formas e sentidos, mas que nos ajudam a compreender as formas de organizações comunitárias do passado, como é o caso do objeto de estudo desta pesquisa – as toponímias. O campo de estudos toponímicos no Brasil se destacou a partir das pesquisas de Levy Cardoso (1961), ao estudar aspectos das formas de nomeações dos lugares, e seguiu seu desenvolvimento por meio dos estudos de pesquisadores como Drumond (1965) e Dick (1980) até o presente momento, em que estudiosos do país têm empreendido esforços na construção do projeto de Atlas Toponímico do Brasil (ATB). Nesse sentido, o presente trabalho objetiva analisar as toponímias indígenas da microrregião cearense do Sertão de Quixeramobim que são classificadas, de acordo com as balizas teórico-metodológicas de Dick (1990), como sendo de natureza antropocultural, ou seja, nomes de lugares que têm sua motivação denominativa relacionada a fatores culturais dos povos indígenas. Dessa forma, o corpus deste trabalho é composto de 03 topônimos da região supracitada. É importante ressaltar que nos atemos à motivação semântica desses topônimos, tecendo considerações acerca da relação entre o léxico toponímico e identidade cultural. Para isso, também utilizamos como aporte teórico Biderman (1998), Hall (2006) e Woodward (2014).
A duratividade na expressão aspectual em libras
Authors: Simonassi Gabriel , Sanchez-Mendes Luciana
Published: January 2021

O presente trabalho apresenta parte dos resultados da dissertação de mestrado intitulada Aspectualidade em Libras: telicidade e duratividade (PIRES, 2019), em que o autor buscou identificar traços semânticos pertinentes na expressão aspectual em Língua Brasileira de Sinais (Libras), bem como o papel desempenhado pelos predicados verbais de diferentes classes acionais (VENDLER, 1957) na referida expressão. Assim, temos como objetivo apresentar como predicados verbais das classes de accomplishment e de atividades na Libras se comportam de modo distinto e influenciam a expressão aspectual dessa língua, tanto na esfera lexical quanto na esfera gramatical. Para isso, observamos as postulações de Comrie (COMRIE, 1976) sobre o tema. Para evidenciar tais fenômenos, adotamos a Elicitação Controlada (MATTHEWSON, 2004) para coletar de forma sistemática e objetiva os dados que julgamos ser pertinentes, uma vez que tal metodologia se mostrou eficaz em trabalhos descritivos com línguas minoritárias. Com base nessa metodologia, adaptamos um teste elaborado por Dowty (DOWTY, 1979) para a língua inglesa, de modo a garantir a sua aplicabilidade fidedigna em uma língua de sinais. Dada a nossa pesquisa, pudemos verificar que nosso consultor optou por diferentes estratégias para expressar a duratividade. Em predicados de accomplishments e atividades, foi adotado um sinal indicativo de passagem de tempo. Em predicados com movimento direcionado (télicos e atélicos) foram utilizadas outras estratégias associadas a aspecto gramatical, como indicar fase preparatória interna de um evento.

Authors: Almeida Aurelina Ariadne Domingues
Published: January 2021

Apresentam-se resultados de uma pesquisa empreendida que objetivou compreender a variação categorial do item léxico xereca no português do Brasil. O estudo norteou-se por pressupostos da Linguística Cognitiva, de sorte que travou diálogos com autores como Salomão (2011; 1997), Lakoff (1987), Rosch (1978), Silva (2015; 2010), além de pressupostos teóricos da Teoria da complexidade, apresentados por Morin (1999) e Capra (2006). No tocante ao seu desenho metodológico, foi desenvolvido através da abordagem qualitativa do corpus, formado por textos postados na internet; teve natureza exploratória, descritiva e interpretativa e buscou compreender as ocorrências no contexto de uso. Concluído o trabalho, constatou-se que esse item do léxico pode ser inserido pelo conceptualizador em diferentes categorias e seu grau de prototipicidade depende de quem o usa e de onde o usa.

This essay will analyze the text "Four theses on the Argentine North" by the Argentine revolutionary leader Mario Roberto "Roby" Santucho, who was the founder of the Workers' Revolutionary Party (PRT) and later of the People's Revolutionary Army (ERP) in the 1970s. The importance of the text lies in its analysis of the productive structures and social classes in which the Northwest Argentine region (NOA) was stratified, and more specifically the province of Tucumán, where the largest sugar production in the country is concentrated , and that it was one of the most important centers of rural revolutionary resistance.
Pralogicity of the psychologist’s thinking in the context of deep-correctional cognition
Authors: Yatsenko Tamara , Galushko Lyubov , Ievtushenko Iryna , Manzhara Svitlana
Published: January 2021

The problem of in-depth correctional cognition of the psyche is its pralogical essence is analyzed in the context of a comprehensive, holistic approach to understanding of the psyche. The article for the first time raises the issue of the role of the pralogical essence of the subject’s thinking that influences the organization of ASPC groups. The attention is focused on the fundamental principles of the functioning of ASPC group that set the prerequisites of conflict-free relations that catalyze detection of the pralogical parameters of the psyche. The latter is stipulated by both visualized self-presentation of the ASPC participants and dialogue interaction of a psychologist with a respondent. The works states the possibility of unseen combination of logical thinking with pralogical one. The study presents the characteristics of the pralogical thinking in their neutrality to the controversies, justifies the pralogical nature of the implicit order, etc. The problems of in-depth cognition and ways of overcoming them are dscribed, particularly those associated with pralogical thinking and archaic predeterminancy of the “implicit order” of the psyche, the contradictory nature of its components, which preserves the subordination to the law “involvement”, discovered by L. Levy-Bruhl. The article reveals the prerequisites for the effectiveness of the ASPC diagnostic and corrective process, subject to the law – “positive disintegration of the psyche and secondary integration at a higher level of its development”. The work asserts that the main problems of the in-depth cognition of the psyche envisage taking into account the motivational potential of archaisms, including non-experience entities in their integration with the individualized characteristics of the subject. The peculiarities of introduction of auxiliary (subjectified) means into the in-depth cognition process that enhances its objectivity are disclosed. Besides, the article describes the problem of the psyche dualism that is inherent not only to the functioning of the conscious and the unconscious spheres, but also to a corresponding latent arrangement of the visualized manifestations of the psyche that reflects the “Model of the psyche internal dynamics”, including the “Yin and Yang” symbol.

Authors: Santos Agnes , Relojo-Howell Dennis
Published: January 2021

The primary focus of this study is to examine the physical, mental, emotional, social, and spiritual components of the lifestyle of older adults, with the fundamental aim of designing a cognitive enhancement programme. A total of 142 older adults have taken part, all of whom have normal cognitive functioning. Results revealed that perceptual organisation has significant relationship to developmental age (F = 3.99, p < 0.021). Processing speed has also been found to have a significant link to developmental age (F = 8.02, p < 0.021), p < 0.001. The gender of older adults has no significant relationship to verbal comprehension, perceptual organisation, working memory, and processing speed. In contrast, working memory is linked to civil status (F = 3.45, p < 0.021), p < 0.01. Processing speed was also found to have a significant relationship to civil status (F = 2.71, p < 0.021), p < 0.03. Finally, educational attainment has no significant link to verbal comprehension, perceptual organisation, working memory, and processing speed.

Published: January 2021

The aim of the study was to determine the spread of pathogens of parasitic diseases in the digestive organs of rabbits in farms of various forms of ownership in Odesa Region. One thousand and two hundred rabbits of different age groups in specialized farms (which they use cage keeping of animals in compliance with all zoohygienic requirements and a balanced feeding ration), as well as 582 rabbits in private farms (which the type of feeding was mixed) were examined. Prevalence of parasitic infections of rabbits in specialized farms is 52.3%, in household farms — 85.1%. In specialized farms, prevalence of cysticercosis is 2.6% (with intensity of 3–7 cysticerci), eimeriosis — 14.0%, trichostrongylosis — 13.6%, and passalurosis — 20.6%, two-component (eimeriosis + cysticercosis) infection —1.0%, three-component (eimeriosis + cysticercosis + passalurosis) infection — 0.5%, total infestation (both mono- and mixed infections) with cysticerci — 4.1%. In homestead farms, prevalence of cysticercosis is 27.7% (with intensity of 21–64 cysticerci), eimeriosis — 15.6%, trichostrongylosis — 3.6%, and passalurosis — 6.7%, two-component (eimeriosis + cysticercosis) infection —24.2%, three-component (eimeriosis + cysticercosis + passalurosis) infection — 7.2%, total infestation (both mono- and mixed infections) with cysticerci — 59.1%. Cysticercosis is a common infection of rabbits in Odesa Region, which occurs often as part of mixed infections with pathogens eimeriosis and pasalurosis. The total infestation of rabbits with cysticerci in homestead farms was 55.0% higher than in specialized ones. One-component infestations in specialized farms is 97.1% of sick rabbits, and in homestead farms — 63.0%; two-component (eimeriosis + cysticercosis) infection — 1.9% and 28.5%, respectively; and three-component (eimeriosis + cysticercosis + passalurosis) infection — 1.0% and 8.5%, respectively

Authors: Ruda M. Ye. , Kozutska T. G. , Yaremenko R. M. , Balanchuk L. V.
Published: January 2021

Today, salmonellosis remains one of the leaders in zoonoses and the cause of toxic infections in humans, which are common throughout the world. The epidemiological feature of salmonellosis is suddenness and mass character. Salmonella is very stable in the environment, and can multiply intensively at 2037°C in various foods: meat and dairy products, sausages, especially blood and liver, jellies, pates, cream confectionery, salads and other dishes. The organization and conduct of laboratory tests for the diagnosis and prevention of salmonellosis is an important component of the epidemiological surveillance system. The aim of the study was to analyze the detection rate of bacteria of the genus Salmonella in food products on the territory of Ukraine in 2019 and to establish the serovars of Salmonella, dangerous to human health. The study and analysis of statistical data was carried out based on the results of research and reports from the regional laboratories of the State Food and Consumer Service of 24 regions of Ukraine, as well as own research conducted in the State Scientific and Research Institute of Laboratory Diagnostics and Veterinary and Sanitary Expertise. According to the results of the research, it was established that 72 isolates of Salmonella spp. were isolated out of 184,951 food samples studied in 2019. Compared to 2018, the number of isolated salmonella from 189,517 samples was 121 isolates, of which dangerous strains of S. Enteritidis (group D) were detected in 25 cases, which is 20.6%, and Salmonella spp. — 32.2% of all isolated salmonella. These variants of salmonella were isolated from meat of various species of animals, poultry co-products, meat semi-finished products, minced meat and mechanically deboned meat, sauce, eggs and feed. In 2017, only 32 isolates of Salmonella were isolated from 142,977 tested samples, mainly Salmonella spp. The products from which this pathogen was isolated differed slightly from the following years, namely: meat, co-products, meat semi-finished products, animal oil, salted fish, fish semi-finished products and cookies. That is, the largest number of isolated salmonella is observed in 2018, although the number of samples in 2019 was slightly lower than in 2018. Thus, the obtained data indicate that it is necessary to follow strictly the sanitary and hygienic rules during the preparation, processing and consumption of food
INVESTIGATION OF THE ANTIOXIDANT POTENTIAL AND TOXICITY OF THE WHOLE LEAF OF SOLANUM NIGRUM IN ALBINO RATS
Authors: Saibu Gbemisola , Adu Oluwatosin
Published: January 2021

Introduction: Solanum nigrum is a common herb that grows wild and abundantly in open fields. Solanum nigrum has been shown to have anti-inflammatory properties. Most animal studies have been on the aqueous and alcoholic extracts of Solanum nigrum leaf, this study focuses on the whole leaf. Aims: The aim of this study was to assess the antioxidant potential and effect of the whole leaf of S. nigrum on liver function parameters in rats. Materials and Methods: Fifteen male Wistar rats were divided into three groups of 5 rats each. Solanum nigrum leaves rinsed,air-dried, milled and administered orally to the rats at two doses (100mg/kg and 200mg/kg body weight in 1% CMC) for seven days. The control group received 1ml of 1% CMC orally for seven days. On the eight day, animals were sacrificed and cardiac blood collected into plain bottles. Standard methods were used to determine serum nitric oxide, lipid peroxidation, gluthathione peroxidase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and total bilirubin. One gram portion of the organs (heart, kidney, liver and spleen) were fixed in formal saline for histopathological examination of 2 animals per group. Results: Solanum nigrum had an LD50 greater than 1000mg/kg body weight without symptoms associated with toxicity. Nitric oxide concentration was significantly lower (p<0.05) in the S. nigrum groups (92.0-118.33mM) compared to the control (238.00mM) whereas gluthathione peroxidase was significantly increased (p<0.05) compared to the control group. The effects on these parameters were not dose dependent. There was no significant change in liver function parameters in all the groups. The histopathological screening of the control and test groups showed normal profile indicating no morphological alterations in the heart, liver, kidney and spleen of the rats. Conclusion: This results indicates the antioxidant effect of Solanum nigrum leaf. It also showed that the consumption of S. nigrum leaves at the chosen doses had no adverse effect on the organs of the rats. Further work will need to be done at higher doses, for longer duration and on both sexes of animals.

A Two-parameter Family of Exponentially-fitted Obrechkoff Methods for Second-order Boundary Value Problems
Authors: Wusu Ashiribo
Published: January 2021

Generally, classical numerical methods may not be well suited for problems with oscillatory or periodic behaviour. To overcome this deficiency, they are modified using a technique called exponential fittings. The modification makes it possible to construct new methods suitable for the efficient integration of oscillatory or periodic problems from classical ones.In this work, a two--parameter family of exponentially--fitted Obrechkoff methods for approaching problems that exhibit oscillatory or periodic behaviour is constructed. The construction is based on a six-step flowchart described in [13]. Unlike the single--frequency method in [21], the constructed methods depend upon two frequencies which can be tuned to solve the problem at hand more accurately. The leading term of the local truncation error of the new family of method can also be easily obtained from the given general expression. The efficiency of the new methods is demonstrated on some numerical examples. This work is related to [20,21] and provides extension to the results obtained in [21]
An Innovative Formulation Tightening Approach for Job-Shop Scheduling
Authors: Yan Bing , Bragin Mikhail , Luh Peter
Published: January 2021

Job shops are an important production environment for low-volume
high-variety manufacturing. Its scheduling has recently been
formulated as an Integer Linear Programming (ILP) problem to take advantages of
popular Mixed-Integer Linear Programming (MILP) methods, e.g., branch-and-cut. When
considering a large number of parts, MILP methods may experience difficulties. To address this, a critical but much overlooked issue is formulation
tightening. The idea is that if problem constraints can be transformed to directly
delineate the problem convex hull in the data preprocessing stage, then a
solution can be obtained by using linear programming methods without much difficulty.
The tightening process, however, is fundamentally challenging because of the
existence of integer variables. In this paper, an innovative and systematic approach
is established for the first time to tighten the formulations of individual
parts, each with multiple operations, in the data preprocessing stage. It is a
major advancement of our previous work on problems with binary and continuous
variables to integer variables. The idea is to first link integer variables to
binary variables by innovatively combining
constraints so that the integer variables are uniquely determined by the
binary variables. With binary and
continuous variables only, it is proved that the vertices of the convex hull
can be obtained based on vertices of the linear problem after relaxing binary
requirements. These vertices are then converted to tight constraints for
general use. This approach significantly improves our previous results on tightening
individual operations. Numerical
results demonstrate significant
benefits on solution quality and computational efficiency. This approach also applies to other ILP problems with
similar characteristics and fundamentally changes the way how such problems are
formulated and solved.

Published: January 2021

The Internet of Things (IoT) is permeating our daily lives where it can provide data collection tools and important measurement to inform our decisions. In addition, they are continually generating massive amounts of data and exchanging essential messages over networks for further analysis. The promise of low communication latency, security enhancement and the efficient utilization of bandwidth leads to the new shift change from Mobile Cloud Computing (MCC) towards Mobile Edge Computing (MEC). In this study, we propose an advanced deep reinforcement resource allocation and securityaware data offloading model that considers the computation and radio resources of industrial IoT devices to guarantee that shared resources between multiple users are utilized in an efficient way. This model is formulated as an optimization problem with the goal of decreasing the consumption of energy and computation delay. This type of problem is NP-hard, due to the curseof-dimensionality challenge, thus, a deep learning optimization approach is presented to find an optimal solution. Additionally, an AES-based cryptographic approach is implemented as a security layer to satisfy data security requirements. Experimental evaluation results show that the proposed model can reduce offloading overhead by up to 13.2% and 64.7% in comparison with full offloading and local execution while scaling well for large-scale devices.

PERSEPSI REMAJA TERHADAP ATRIBUT KENYAMANAN PADA SETTING ALUN-ALUN PURWOKERTO SEBELUM DI RENOVASI
Authors: Yudono Yohanes Wahyu Dwi
Published: January 2021

Pemahaman suatu lingkungan fisik, didasarkan pada persepsi pengguna terhadap properti yang ada di dalam settingnya.  Persepsi tidak bersifat pasif dalam menerima masukan yang berupa stimulus yang berasal dari luar diri manusia. Selanjutnya melalui keberadaan properti yang ada di dalam setting yang berlaku sebagai stimulus, akan dikirimkan dari mata ke otak untuk dipahami dan diberi makna berdasarkan pengalaman masing-masing pengguna. Dengan demikian dapat dirumuskan tentang dugaan penyebab munculnya makna ganda pada fenomena setting alun-alun Purwokerto, yaitu adanya perbedaan persepsi  sebagai akibat pegeseran fungsi dalam konsepsi ruang berkumpul. Adapun perbedaan persepsi yang dimaksud, menyangkut faktor internal individu (pengguna alun-alun, dalam hal ini remaja) yang berupa motiv, harapan, dan minat remaja terhadap setting alun-alun. Penelitian ini dilakukan untuk melihat hubungan keterkaitan antara persepsi remaja terhadap atribut ruang berkumpul pada setting alun-alun Purwokerto. Teori operasional dibangun dengan mendasarkan pada teori Weismann (1981) tentang atribut sebagai variabel bebas, serta teori Paull. A. Bell, dkk (1978) tentang persepsi dan teori Atkinson Rita. L, dkk (1983) tentang faktor internal sebagai variabel terikat. Sedangkan metoda analisis yang digunakan dalam penelitian ini adalah dengan perhitungan statistik deskriptif. Penelitian ini dilakukan untuk melihat hubungan keterkaitan antara persepsi remaja terhadap atribut kenyamanan ruang berkumpul pada setting alun-alun Purwokerto. Sedang hasil penelitian menunjukan: persepsi remaja terhadap atribut kenyamanan berdasar kondisi udara segar 32,65%, kondisi pencahayaan 26,53%, dan kondisi ketenangan suasana 14,28%.
