Através da narrativa autobiográfica e da metodologia a/r/tográfica, a autora narra e reflete sobre a pesquisa, a criação artística e as reverberações educativas do seu trabalho, com a intenção de fomentar, em sua comunidade, a ideia de preservação da memória dos sonhos. O bordado livre é a técnica escolhida para este “trabalho de aranha” de construção de redes e, também, para o desafio das representações imagéticas, emaranhando texto, arte têxtil, sonhos e utopias.
Reflexões sobre o pensamento pictórico no estudo da interação das cores baseado em Wassily Kandinsky
Authors: Fuhrmann Lisy Li Pires , Ruiz Raony Robson , Lampert Jociele
Published: February 2023

Esta pesquisa investiga as práticas docentes para o ensino da interação da cor desenvolvida pelo projeto de pesquisa intitulado O Estúdio de Pintura como um Laboratório de Ensino na Universidade do Estado de Santa Catarina – UDESC. Para a realização desta, o objetivo geral foi de investigar como propostas de aula ateliê sobre a interação das cores a partir de Kandinsky podem contribuir para o desenvolvimento do pensamento pictórico na pintura, dividido em três objetivos específicos: (1) Analisar a teoria das cores em Kandinsky, (2) Apresentar a abordagem utilizada na regência ministrada na disciplina de Introdução a Linguagem Pictórica (3) análise dos dados coletados da regência. Como metodologia utilizou-se a abordagem da pesquisa qualitativa envolvendo a análise de fontes documentais primárias de uma regência ministrada com os alunos de graduação em artes visuais e de revisão bibliográfica sobre o tema investigado. Obteve-se 3 tipos de resultados diferentes considerando o processo pictórico dos alunos na execução dos desafios que ocorreram das seguintes maneiras: pintando primeiro o filtro e depois as formas; ou as formas e em seguida uma camada de tinta para representar o filtro; ou a interação das cores nas formas sem representar o filtro, com isto identificamos como a partir de um mesmo desafio os alunos encontraram caminhos diferentes para a solução deste, alguns evidenciando a forma, outros a interação da cor.

Published: February 2023

Este ensaio é fruto dos encontros do grupo de estudos “Sábados com Deleuze”, ocorridos de 2015 a 2019, na Universidade Federal de Santa Maria – RS/Brasil, com o objetivo de problematizar as conversações e os contágios que as obras estudadas dispararam no encontro com práticas artísticas e a pesquisa em educação. Algumas imagens compõem o texto, dando expressão às experimentações que ocorreram nesse sentido ao longo dos encontros de estudos. Em uma movimentação biografemática (BARTHES, 2003), este trabalho foi produzido a oito mãos, isto é, por quatro singularidades povoadas por uma polifonia de vozes que ressoam e são sinalizadas nesta escrita como: 1º, 2º, 3º e 4º par de mãos. Cada autor/a tecia sua escrita e enviava para o par subsequente, explorando regiões ainda não imaginadas. As zonas textuais resultantes desse procedimento de escrileitura (CORAZZA, 2008) intentam convidar o/a leitor/a a explorar modos de ver, ler, escrever, viver na academia em inter-relação com arte e filosofia enquanto campos de criação.

Published: February 2023

Este artigo analisa a multiplicidade de termos adotados para caracterizar práticas artísticas colaborativas e participativas, para tanto, elenca definições que surgiram a partir da década de 1990 e suas particularidades. A investigação se justifica tanto por sugerir um mapeamento e uma organização cronológica desses estudos e desses modos de atuar no campo da arte, bem como por valorizar as especificidades dessas abordagens teóricas, distinguindo-as: novo gênero de arte pública, arte de margens, arte baseada em comunidades, estética relacional, arte dialógica, arte intervencionista, arte socialmente engajada, estética de emergência, virada social, arte participativa, virada pedagógica e arte colaborativa. Entre os objetivos desta pesquisa está refletir sobre a aproximação do público com essa tendência da produção contemporânea, incentivada por diversos autores situados em diferentes contextos locais. Para isso, se estabeleceu uma abordagem qualitativa e de levantamento bibliográfico, tratando-se de aportes dos teóricos principais, tais como: Suzanne Lacy, (1994), Bruce Barber, (1996), Deidre Williams (1997), Nicolas Bourriaud (1998) Grant H. Kester (1998, 2004, 2011, 2012), Jonas Ekeberg (2003), Claire Bishop (2006, 2008, 2012) e Reinaldo Laddaga (2006).

Authors: Cidreira Renata Pitombo , Leahy Renata Costa
Published: February 2023

Este artigo é fruto da vertente baiana da pesquisa interinstitucional Escolas de Artes e Ofícios no Brasil: história, propostas formativas e continuidades na formação do Bacharelado em Design de Moda. De natureza qualitativa, a pesquisa prioriza uma linha de investigação histórica, analisando o Liceu de Artes e Ofícios da Bahia (1872-2007), seus primórdios e desenvolvimento, na busca de vestígios do ensino voltado a atividades vestimentares, como corte e costura. Nesse percurso, tentamos compreender o papel da instituição na formação de cidadãos, sobretudo a partir da conjuntura social que se colocava à época do seu surgimento, de uma população recém-liberta da escravidão em uma cidade em vias de industrialização. Além disso, procura compreender qual papel o Liceu de Artes e Ofícios da Bahia cumpre na sociedade soteropolitana, sobretudo nas décadas de 1990 e 2000, inquerindo se teve como direcionamento o ensino de modelagem e costura. Em termos metodológicos, a investigação utilizou como principal recurso a pesquisa bibliográfica, reunindo informações sobre a instituição e o contexto socioeducativo baiano através dos trabalhos de Cunha (1979), Leal (1996), Trinchão (2008) e Reis (2012), com amparo em questionário com alguns profissionais que atuaram na instituição no período mais recente. Conclui-se que o Liceu de Artes e Ofícios da Bahia perpetuou seu objetivo principal de assistir e formar classes menos favorecidas economicamente. Não houve maior desenvolvimento de atividades relacionadas às práticas vestimentares, das quais somente foram encontrados vestígios. Nos seus últimos anos, o Liceu atuou para promover uma formação cidadã através das artes.

O iluminador xamã, bricoleur cósmico e o olhar índio da criança no teatro infantil
Authors: Souza Fernanda Guimarães Mattos de
Published: February 2023

Propomos aqui, a análise do iluminador cênico como xamã e da criança como espectadora, ambos com seus respectivos olhares índios, dentro de uma construção artística ou imaginária que seja de bricolagem. A recepção da criança em um espetáculo infantil, selecionando visualmente tudo o que quer da cena, engendra um novo universo de compreensão do que presencia no teatro. Trata-se da relação entre xamã-iluminador como bricoleur cósmico e a recepção do público infantil, a partir de um pacto de sonho lúcido estabelecido entre ambos por meio de um rigoroso olhar índio, o olhar do bricoleur, que cria artefatos artísticos ou espirituais que refuncionalizam e reordenam o mundo naquele espetáculo.
Instalação sonora ou instrumento musical?: um estudo de fronteiras a partir da obra Balance
Authors: Boscato Arthur Zucchi , Barros Guilherme Sauerbronn de
Published: February 2023

O presente trabalho propõe, a partir das (re)definições da noção de instrumento musical propostas por Schaeffer (1966) e Chion (2009), uma intersecção entre instrumento musical e instalação sonora. A proposta surge da provocação suscitada pela obra Balance., instalação sonora composta utilizando o fenômeno da realimentação (em que um som é captado por um microfone, reproduzido em um alto-falante e captado novamente, fazendo emergir um ciclo infinito) e o controle de sua plasticidade através de uma câmera que capta os movimentos do corpo do interagente. Uma segunda seção é dedicada ao relato do processo de composição e de programação no ambiente gráfico Pure Data.

Authors: Pinto Jailson Mauricio , Silva Marcelo Barreto da , Brochado Lucas Neves , Bianchini Amanda Pessotti , Barreto Alice Barbutti
Published: February 2023

The coconut palm Cocos nucifera L, is a cultivar that arrived in Brazil around 1553 by the Portuguese and expanded along the entire coast of the country, with commercial production in four regions: North, Northeast, Midwest and Southeast. The cultivar has great relevance in the agroindustry. However, coconut cultivation has been affected by diseases, among them, coconut sandpaper, which causes losses of up to 50% in production, if there is no control. The objective of this research was to analyze the studies already carried out on biological control in combating coconut sandpaper. The hypothesis that motivated the research considers that the biological control carried out has left gaps that need to be studied, explored and presented in future research.
A Qualitative Study of Changes in Adolescent Dietary Behavior during the COVID-19 Pandemic and Improvement Strategies for School-Provided Nutrition Counseling
Authors: Na Yeseul , Oh Jieun , Lee Kyung Won
Published: February 2023

This study utilized qualitative research to understand the changes taking place in adolescent dietary behaviors during the COVID-19 pandemic and the current status of school-provided nutrition counseling. These, along with barriers and strategies for improvement, were derived from focus group interviews with 10 nutrition teachers. Throughout the pandemic, adolescents experienced various dietary problems, including frequent meal skipping, unbalanced diets, increased obesity, and difficulties building positive attitudes towards food. To resolve these dietary problems, nutrition teachers recognized the need for school-provided nutrition counseling. However, nutrition teachers faced various barriers, such as a lack of time for nutrition counseling among students, lack of support from parents, and insufficient space and resources. To revitalize school-provided nutrition counseling, strategies such as home-connected nutrition counseling, the development of standardized guidelines, manuals for school-provided nutrition counseling, software support for nutrition diagnosis, and implementation of nutrition counseling in connection with cooking activities were proposed. This is important as school-provided nutrition counseling can help develop the foundation for healthy dietary behaviors and health promotion in adolescents.

Authors: Lee Sanghee , Kwon Sookhee
Published: February 2023

Dressmaking is a high value-added sector of the fashion industry in which the individuality and skills of designers play a prominent role. The appropriate use of the draping and the flat pattern techniques in the dressmaking process also play an important part in perfecting the finished product. The purpose of this study was to improve the understanding of dress design and identify a pattern production technique to enhence efficiency in each of the three elements of the dress manufactureing process. For this purpose, analysis of the design of 1,389 wedding dress photographs published in Wedding 21, Korea’s leading wedding magazine, during 2019 and 2020 was conducted. This analysis identified 15 bodice designs and 11 sleeve designs based on neckline and eight skirts based on silhouette which were ranked by frequency distribution. Patterns for the design of samples were then developed according to the highest combined frequency distribution of these three elements. Eight samples were finally produced to test the the efficiency of the patternmaking techniques empolyed and the selected designs. The findings from this study have practical applications, notably in improving the efficiency of pattern production techniques that will facilitate further growth in the dressmaking industry.
Development of a Housing Choice Behavior Program for Middle-School Home Economics to Cultivate Housing Value Orientation
Authors: Ko Eun A , Jee Eun Young
Published: February 2023

The purpose of this study was to develop a housing choice behavior program to cultivate housing value orientation among middle-school students. The importance of cultivating housing value orientation in middle school was examined by investigating the relationship between housing value orientation and housing choice behavior, following which a program was developed to cultivate housing value orientation based on various housing values. Housing choice behavior was defined as selecting the ownership type, housing type, housing size, and neighborhood environment of housing, and the program was developed in 12 sessions to understand housing values and cultivate housing value orientation through learning housing choice behavior. The features of this program were as follows. First, although housing choice behavior is not covered in middle-school home economics, the 2015 revised national curriculum and current middle-school textbooks were analyzed and developed in consideration of the level available in schools. Second, it was possible to develop a housing value orientation that encompasses various housing values, including activities used to consider such values as the basis for housing choice behavior by each sessions. Third, the program was meaningful in that it developed practical problem-solving and living independence skills through learning activities, including available sites, experience cases, and housing welfare that cannot be experienced directly or indirectly.
Manager-Level Businesswomen’s Personal Experiences of Appearance Management and Body Image
Authors: Lee Yoon-Jung , Lee Goeun , Lee Minsun
Published: February 2023

The purpose of this study was to explore the personal experiences of businesswomen regarding appearance management and their body image. To achieve this, diverse perspectives were employed, including critical, practical, and positive body image perspectives. Interviews were conducted with 17 Korean businesswomen with more than 10 years of work experience. The data were analyzed using a phenomenological approach to understand their lived experiences of appearance management and body image. The participants acknowledged that appearance is important in the workplace - more so for women than for men. They commented that appearance may play an important role in displyaing social attractiveness to strangers, but other elements of social attractiveness such as liveliness or social skills take prominence in established relationships. Businesswomen, particularly those whose professions involve the display of appearance, are more likely to engage in aesthetic labor or the unpaid labor of managing their physical appearance in order to meet expectations at work. In general, however, these women considered appearance management to be a practice of self-care which seems to demonstrate their positive body image. This study has significance in that it strived to understand the subjective, lived experiences of businesswomen, including their thoughts and emotions related to appearance management and body image.
The Mediating Effect of Internalized Shame on the Relationship between Affiliate Stigma and Interpersonal Anxiety among Adolescent Siblings of Individuals with Autism Spectrum Disorder
Authors: Jeong Soui , Park Ju Hee
Published: February 2023

The study examined the mediating effect of internalized shame on the relationship between affiliate stigma and interpersonal anxiety among adolescents with siblings who had autism spectrum disorder (ASD) and the moderated mediating effect of mother-adolescent communication openness. The participants consisted of 139 adolescents (boys 48.9%, high-school students 79.8%) who had siblings with ASD. Interpersonal anxiety, affiliate stigma, internalized shame, and mother-adolescent communication openness were measured using the Social Anxiety Scale for Adolescents (La Greca & Lopez, 1998), the Affiliate Stigma Scale (Mak & Cheung, 2008), the Internalized Shame Scale (Cook, 1988), and the Parent-Adolescent Communication Scale (Barnes & Olson, 1982), respectively. The data were analyzed using descriptive statistics and Pearson’s correlation coefficients. Process Macro Models 4 and 7 were used to examine the mediating effect and the moderated mediating effect. The results indicated that internalized shame mediated the effect of affiliate stigma on interpersonal anxiety among adolescents who had siblings with ASD. However, there was no significant moderated mediating effect of mother-adolescent communication openness on the relationship between affiliate stigma, internalized shame and interpersonal anxiety. These findings suggest that it is necessary to improve social awareness of individuals with ASD and their family members to prevent adolescents who have siblings with ASD from having affiliate stigma and to help them reduce interpersonal anxiety. The results also highlight the importance of counseling programs for adolescents with siblings with ASD as a way of preventing or alleviating their interpersonal anxiety by reducing internalized shame, even where they experience affiliate stigma.

Authors: Hwang Jiyeon , Kim Joonmi , Seo Eunae , Shin Hyojung
Published: February 2023

This research was conducted in order to examine previous studies on paternal parenting methods involving adolescent children in terms of their academic field, research period, method and subjects, and family variables. A total of 104 research publications from the period between 2003 and 2022 were investigated, with 99 quantitative research (43 theses and 56 academic journals) and five qualitative data sources. The analysis results show that the topic of fathers with adolescent children was the most studied in the field of education, and it rapidly increased from 2011 to 2014 and then rapidly decreased from 2019. The main subject of the studies was middle-school students, while most of the studies adopted a quantitative approach, with a minimal number of qualitative studies. Parenting studies were concentrated on father variables and several such studies were found to be related to positive resources such as self-esteem and self-efficacy as variables of adolescent children related to fathers’ parenting. The results of these studies provide meaningful implications for future research on the fathers of adolescent children and can be used as basic data for developing detailed education and programs.

Authors: Lim Na Rae , Choi Soo Yeon , Chung Woo Chul
Published: February 2023

Background/Aims: The effects of probiotic supplementation on Helicobacter pylori (H. pylori) eradication therapy are not completely understood. In this study, we investigated the effects of continuous probiotic administration on eradication rates, recrudescence, and symptom response following completion of a course of H. pylori therapy.Methods: This prospective, randomized, double-blind placebo-controlled trial was performed between June 2018 and 2020. Twohundred seventy patients who received a standard triple regimen for H. pylori eradication, were included in the study. Participants were randomized to receive a probiotic as adjunctive therapy (Enterococcus faecium 4.5×108 and Bacillus subtilis 5.0×107; Medilac-S®, Hanmi Pharmaceuticals, Seoul, Korea) or a placebo (one tablet thrice daily) for 28 days, following H. pylori eradication. Participants who showed successful eradication underwent a repeat 13C-urea breath test after 6 months.Results: Eradication rates in the probiotic and placebo groups were 77.1% and 72.4%, respectively (P=0.48) using per-protocol analysis. Using intention-to-treat analysis, eradication rates were 67.4% and 65.9%, respectively (P=0.43). Of 149 patients who were followed-up after 6 months, four patients had recrudescence (2.7%). Recrudescence rates did not differ between the probiotic and placebo groups. Of the 76 patients who had non-ulcer dyspepsia, 60 (78.9%) showed symptom resolution after 6 months. This beneficial effect was most pronounced in patients with postprandial distress syndrome (P=0.02).Conclusions: Consecutive probiotic supplementation following H. pylori eradication therapy did not increase eradication rates or decrease recrudescence rates.
Is Xenopus laevis introduction linked with Ranavirus incursion, persistence and spread in Chile?
Authors: Peñafiel-Ricaurte Alexandra , Price Stephen J. , Leung William T.M. , Alvarado-Rybak Mario , Espinoza-Zambrano Andrés , Valdivia Catalina , Cunningham Andrew A. , Azat Claudio
Published: February 2023

Ranaviruses have been associated with amphibian, fish and reptile mortality events worldwide and with amphibian population declines in parts of Europe. Xenopus laevis is a widespread invasive amphibian species in Chile. Recently, Frog virus 3 (FV3), the type species of the Ranavirus genus, was detected in two wild populations of this frog near Santiago in Chile, however, the extent of ranavirus infection in this country remains unknown. To obtain more information about the origin of ranavirus in Chile, its distribution, species affected, and the role of invasive amphibians and freshwater fish in the epidemiology of ranavirus, a surveillance study comprising wild and farmed amphibians and wild fish over a large latitudinal gradient (2,500 km) was carried out in 2015–2017. In total, 1,752 amphibians and 496 fish were tested using a ranavirus-specific qPCR assay, and positive samples were analyzed for virus characterization through whole genome sequencing of viral DNA obtained from infected tissue. Ranavirus was detected at low viral loads in nine of 1,011 X. laevis from four populations in central Chile. No other amphibian or fish species tested were positive for ranavirus, suggesting ranavirus is not threatening native Chilean species yet. Phylogenetic analysis of partial ranavirus sequences showed 100% similarity with FV3. Our results show a restricted range of ranavirus infection in central Chile, coinciding with X. laevis presence, and suggest that FV3 may have entered the country through infected X. laevis, which appears to act as a competent reservoir host, and may contribute to the spread the virus locally as it invades new areas, and globally through the pet trade.
Stress-induced immunosuppression affecting immune response to Newcastle disease virus vaccine through “miR-155-CTLA-4” pathway in chickens
Authors: Wen Jie , Wu Yiru , Han Jianwei , Tian Yufei , Man Chaolai
Published: February 2023

MiR-155 and CTLA-4 are important factors involved in the regulation of immune function. However, there is no report about their involvement in function regulation of stress-induced immunosuppression affecting immune response. In this study, the chicken model of stress-induced immunosuppression affecting immune response (simulation with dexamethasone and immunization with Newcastle disease virus (NDV) attenuated vaccine) was established, then the expression characteristics of miR-155 and CTLA-4 gene were analyzed at several key time points during the processes of stress-induced immunosuppression affecting NDV vaccine immune response at serum and tissue levels. The results showed that miR-155 and CTLA-4 were the key factors involved in stress-induced immunosuppression and NDV immune response, whose functions involved in the regulation of immune function were different in different tissues and time points, and 2 day post immunization (dpi), 5dpi and 21dpi were the possible key regulatory time points. CTLA-4, the target gene of miR-155, had significant game regulation relationships between them in various tissues, such as bursa of Fabricius, thymus and liver, indicating that miR-155-CTLA-4 pathway was one of the main mechanisms of their involvement in the regulations of stress-induced immunosuppression affecting NDV immune response. This study can lay the foundation for in-depth exploration of miR-155-CTLA-4 pathway involved in the regulation of immune function.
Analysis of urine Raman spectra differences from patients with diabetes mellitus and renal pathologies
Authors: Kavuru Varun , Senger Ryan S. , Robertson John L. , Choudhury Devasmita
Published: February 2023

Background

Chronic kidney disease (CKD) poses a major public health burden. Diabetes mellitus (DM) is one of the major causes of CKD. In patients with DM, it can be difficult to differentiate diabetic kidney disease (DKD) from other causes of glomerular damage; it should not be assumed that all DM patients with decreased eGFR and/or proteinuria have DKD. Renal biopsy is the standard for definitive diagnosis, but other less invasive methods may provide clinical benefit. As previously reported, Raman spectroscopy of CKD patient urine with statistical and chemometric modeling may provide a novel, non-invasive methodology for discriminating between renal pathologies.

Methods

Urine samples were collected from renal biopsied and non-biopsied patients presenting with CKD secondary to DM and non-diabetic kidney disease. Samples were analyzed by Raman spectroscopy, baselined with the ISREA algorithm, and subjected to chemometric modeling. Leave-one-out cross-validation was used to assess the predictive capabilities of the model.

Results

This proof-of-concept study consisted of 263 samples, including renal biopsied, non-biopsied diabetic and non-diabetic CKD patients, healthy volunteers, and the Surine™ urinalysis control. Urine samples of DKD patients and those with immune-mediated nephropathy (IMN) were distinguished from one another with 82% sensitivity, specificity, positive-predictive value (PPV), and negative-predictive value (NPV). Among urine samples from all biopsied CKD patients, renal neoplasia was identified in urine with 100% sensitivity, specificity, PPV, and NPV, and membranous nephropathy was identified with 66.7% sensitivity, 96.4% specificity, 80.0% PPV, and 93.1% NPV. Finally, DKD was identified among a population of 150 patient urine samples containing biopsy-confirmed DKD, other biopsy-confirmed glomerular pathologies, un-biopsied non-diabetic CKD patients (no DKD), healthy volunteers, and Surine™ with 36.4% sensitivity, 97.8% specificity, 57.1% PPV, and 95.1% NPV. The model was used to screen un-biopsied diabetic CKD patients and identified DKD in more than 8% of this population. IMN in diabetic patients was identified among a similarly sized and diverse population with 83.3% sensitivity, 97.7% specificity, 62.5% PPV, and 99.2% NPV. Finally, IMN in non-diabetic patients was identified with 50.0% sensitivity, 99.4% specificity, 75.0% PPV, and 98.3% NPV.

Conclusions

Raman spectroscopy of urine with chemometric analysis may be able to differentiate between DKD, IMN, and other glomerular diseases. Future work will further characterize CKD stages and glomerular pathology, while assessing and controlling for differences in factors such as comorbidities, disease severity, and other lab parameters.

Authors: Chapagain Tika Ram , Yadav Surendra Prasad , Sharma Sabita , Shrestha Surendra Lal
Published: February 2023

An experiment was conducted to evaluate the effect of black plastic mulch on yield and other associated characters of promising tomato genotypes developed by the National Horticulture Research Centre, Nepal at the Directorate of Agricultural Research, Tarahara, Nepal, during the winter season of 2019. Nine tomato genotypes (HRDTOM 011, HRD 109, HRDTOM 035, HRDTOM 080, HRDTOM 079, HRDTOM 084, HRDTOM 085, HRDTOM 086, and Pusa Ruby as a check) were evaluated in a randomized complete block design (RCBD) with three replications. Genotypes were transplanted 60 cm apart. Analysis of variance showed significant differences for marketable fruits and yield per plant, average fruit weight, total marketable and unmarketable fruit yield, and total fruit yield. Among the tested genotypes, HARDTOM 011 developed the highest (174) number of marketable fruits per plant with the lowest (12.92 g) individual average fruit weight. In contrast, HRDTOM 080 produced the lowest (36) number of marketable fruits per plant with the highest (49.70 g) individual fruit weight.  HRD 109 and Pusa Ruby provided the highest (69.74 t ha-1) and the lowest (38.51 t ha-1) marketable fruit yields, respectively. The highest total fruit yield was also obtained from the HRD 109. Similarly, HRDTOM 085 and HRDTOM 035 had the highest total soluble solids and fruit size, respectively. Firmness of the fruit and pH content did not differ among the genotypes. With the same genotypes and location (Tarahara), a 98% greater yield demonstrated that tomato production may be significantly boosted with the use of polyethylene film as a mulching medium in winter tomato production in Nepal.
Bipartite Domination in Some Classes of Graphs
Authors: Pelias Winelyn P. , Jr. Isagani S. Cabahug
Published: February 2023

For a nontrivial connected graph G, a non-empty set S \(\subseteq\) V (G) is a bipartite dominating set of graph G, if the subgraph G[S] induced by S is bipartite and for every vertex not in S is dominated by any vertex in S. The bipartite domination number denoted by \(\gamma\)bip(G) of graph G is the minimum cardinality of a bipartite dominating set G. In this paper, we determine the exact bipartite domination number of path graph and cycle graph via congruence modulo.

We simplify the rules of chess. We assume that the initial configuration of pieces is not fixed and satisfies some general conditions. Let I denote the set of all these configurations. By our assumptions, for every C \(\in\) I, after 0 or more moves, the configuration obtained from C and the information who has a move determine the set of all ways of continuing the game i.e. the reachable position. For C \(\in\) I, let R(C) denote the set of all reachable positions obtained from C. A short program shows that card (I) = 65141475298198504104226577310812726424036 and  card < 42959232120882551923988994948073848799479217319544.

Mining is an important economic activity globally that is associated with provision of raw materials, industrial growth, employment creation as well as degradation of natural ecosystems and agricultural land. A study was conducted at Base Titanium limited mining company to evaluate the response of maize-green intercrop to farmyard manure and mineral fertilizer in post mined soils.  Treatments were sole manure, sole inorganic fertilizer, manure + inorganic fertilizer and unfertilized (control) laid down in randomised complete block design (RCBD) and replicated three times.  Data collected included soil nutrients before and after cropping, maize and green grams growth and yield parameters. Obtained data was subjected to analysis of variance using genstat software and means separated using Fisher's LSD. The post mined soils were slightly acidic with optimal levels of Ca, Mg, Mn and Zn, Low levels of P,K, S, B,Cu, CEC, TN and organic matter. After two cropping seasons, S and TN was observed to increase in all treatments, while Ca, Mg, Mn, B and Zn decreased in all treatments. Combined manure and fertilizer application increased average maize plant height, stem circumference and LAI by 38%, 34%, 60% respectively and ears per plant, cob length, grains per cob, grain yield and dry matter weight by 57%, 13%, 47%, 31% and 35% respectively compared to unfertilized plants. Green grams growth and yield in the intercropping system was however not significant after either manure and/or fertilizer application. Although the findings showed that manures and fertilizers application improved nutrient availability in this post mined soils, further research is required to ascertain maize–green gram intercrop, optimal establishment time, spacing, fertilizer and manure rates that can provide optimal intercrop yield as well as soil regeneration.

Kernels of cashew (Anacardium occidentale L.) possess an enormous nutritional and technological potential. However, the almond is less consumed and processed by food industries in Côte d’Ivoire. The present study aims to bring added value to cashew kernel. The effect of this cashew almond extract was tested on fermentative activity of two lactic bacteria (Lactobacillus delbrueckii subsp bulgaricus and Streptococcus salivarius subsp thermophilus) specific for yoghurt production.

The study consisted of making seven formulations composed of milk and aqueous extract of cashew almond. Different formulations namely F0, F1, F2, F3, F4, F5 and F6

contained 0%, 5%, 10%, 15%, 20%, 25% and 30% respectively of aqueous extract of cashew almond. Lactic ferment containing the above lactic bacteria was used for fermentation of each formulation.

Effect of aqueous extract from cashew almond on fermentative activity of the two bacteria was carried out by pH, titratable acidity with duration of fermentation to obtain 80 Dornic degrees.

The results showed that the fermentative activity of lactic bacteria tested was improved with formulations with 15% (F3) and 20% (F4). With these two formulations, the acidity of the yogurt reaches 80° D compared to the standard (F0%). The extract therefore seems to stimulate the activity of bacteria at these two rates. Beyond 20% of cashew almond extract, the extract seems to inhibit the activity of lactic acid bacteria. The aqueous extract of cashew almond may play a role in yogurt-like fermented milk technology.

Aims: The conversion of fallow land for the establishment of new orchards is now an alternative to Ivorian coffee growing, which has long been based on the extensive and shifting cultivation system favoured in the past by the abundance of forest reserves.

Study Design: Thus, three fallow soils under coffee trees were studied from a physical-chemical point of view in order to determine their potential for the productivity of new coffee varieties (Coffea canephora Pierre, var. Robusta).

Place and Duration of Study: The study was conducted on the National Centre of Agriculture Research (CNRA) research station at Abengourou, Divo and Man for six months, between June and November.

Methodology: Soil samples and coffee leaves were collected and analyzed in the laboratory according to standard methods to determine their chemical status. Plant growth (height, crown diameter, number of orthotropic, number and length of plagiotropic internodes) was studied in relation to the physical-chemical characteristics of the soil.

Results: The chemical potential of the soils was found to be low overall. Soil deficiency was characterized by low base saturation (less than 30%), organic matter, nitrogen and cation imbalance, as regard as potassium (K), calcium (Ca) and magnesium (Mg). Growth parameters of the coffee trees and their nutritional status were correlated with the physicochemical properties of the soil.

Conclusion: In view of these results, sustainable coffee production requires an improvement in the level of soil fertility under coffee trees.

THE EFFECT OF COMMODITY SUPERCYCLE AND DOMESTIC MARKET OBLIGATION ON PROFITABILITY RATIO (NET PROFIT MARGIN, RETURN ON ASSET) CASE STUDY ON COAL MINING ISSUERS IN INDONESIA STOCK EXCHANGE
Authors: Wildani Muhammad Alfan
Published: February 2023

The Covid-19 pandemic has resulted in economic paralysis due to the economy and human mobility. This resulted in demand for commodities that occurred simultaneously with conditions that were already improving, causing the supply to be unable to meet demand because the world's industrialized countries continued to boost their economic activities. This led to a very large demand for commodities, opening up coalescing commodities in general which soared simultaneously and formed a super cycle in commodities. Coal commo­dities that occur very quickly are certainly very profitable for coal mining companies. Based on the results of the regression in the study, it shows an increase in the reference price of coal which in this study uses the price of coal at Newcastle Port. It can be seen that one point of increase in the price of coal will affect an increase of 0.173 in return on assets and 0.111 in the net profit margin of coal mining issuers listed on the Indonesia Stock Exchange. The influence of the independent variable supercycle commodities, which in this study uses coal samples and the Domestic Market Obligation (DMO) policy, proved to have an effect and positive value on the dependent variable.

Engaged employees tend to produce better results, which no doubt will bring benefits to organizations. Unfortunately, in Indonesia, only 25% of Millennial employees are engaged, while Millennial employees have occupied 35% of the total workforce. This research aims to identify the influence of the seven determinants of employee engagement, namely work environment, leadership, co-worker relationship, training and career development, compensation, organizational policies, and workplace well-being, on the engagement level of Millenial employees in one of the fastest growing industry in Indonesia, which is the Cafe and Restaurant Industry. The initial 115 data have been gathered, and multiple regression analysis shows that the seven determinants explained 93.6% of the variance in employee engagement (Adjusted R2=0.936, F=239.174, p<.000). Furthermore, only five factors show a significant individual influence on the engagement level: leadership (b=328, p<.000), co-worker relationship (b=.239, p<.004), training and career development (b=254, p<.011), compensation (b=383, p<.001), and workplace well-being (b=176, p<.005). Implications for these findings are discussed in the full paper.
Research and practice

This article reports on research into 25 dissertations written by students in the Master of Psychotherapy programme at Auckland University of Technology in the two years 2021 and 2022. The article focuses specifically on the contribution that these dissertations make to the discipline area. This is contextualised with reference to three gaps, or perceived gaps: between research and practice, researchers and practitioners, and publishing and reading. Based on an empirical-deductive approach to the analysis of the dissertations reviewed, the article reports these contributions; assesses their tone; and suggests that, while the sections of the dissertations regarding these specific contributions are varied and, in some cases, limited, the students/researchers make some important points about the discipline area of psychotherapy with regard to practice and education/training.
Comparison of the Differences in Impact Factor according to Loading Conditions in the Evaluation of Load Carrying Capacity of a High-speed Railway PSC BOX Girder Bridge
Authors: Choi Junhyeok
Published: February 2023

In this study, the load carrying capacity was evaluated using the results of the dynamic load test, instead of the static load test of the field, in the precision safety diagnosis of a high-speed railway PSC BOX girder bridge, and the differences in the impact factor of the bridge according to the load condition of the train and the configuration of the bridge were compared. The impact factor of the bridge was obtained from the measured displacement response via static and dynamic tests for the precision safety diagnosis performed on high-speed railway bridges. The analysis conditions included the location of the sensor, running track of the train, type and span of the bridge, and load condition of the dynamic load test train, test running train, and service train. Consequently, when the impact factor was calculated based on the displacement response of the test running train, instead of the static load test in the load capacity evaluation of the bridge, a difference of -4.96-5.93% was obtained in comparison with the calculation based on the displacement response of the static load test; this corresponds to 0.943-1.053 times the basic load-carrying capacity rate, indicating a difference from the load-carrying capacity rate obtained by the static load test.
