Literatura de cordel: uma possibilidade pedagógica na prática do cotidiano curricular e cultural da educação de jovens e adultos
Authors: Dos Santos Veridiano Maia
Published: April 2017

Resumo: O projeto Literatura de Cordel na Educação de Jovens e Adultos (EJA) foi desenvolvido entre 2008 e 2009 durante as aulas de Arte em turmas de nível III na Escola Municipal Professor Amadeu Araújo, em Natal (RN). Os objetivos foram levar o aluno a apreciar e conhecer a linguagem da poesia popular de cordel como elemento significativo na formação cultural do povo brasileiro, especialmente da Região Nordeste, e mediar a criação e construção de histórias em formato de cordel pelos alunos da EJA como forma de propiciar a criatividade, mediante metodologias pedagógicas que articulassem maior envolvimento com uma das expressões culturais mais latentes do conhecimento popular. Essa forma de literatura foi trazida para o Brasil pelos portugueses e ganhou importância singular na cultura popular brasileira, sobretudo na Região Nordeste do país. Advinda do romanceiro europeu, a literatura de cordel aborda histórias de cavalaria, heróis, reis, lendas e mitos. No Brasil serviu como fator de divulgação de notícias, contos populares, denúncia de abusos da política e reflexo da dura situação social do nordestino (sertanejo, especialmente). Com sua linguagem simples, musicada, imagética e pautada em estruturas de rimas populares organizadas em estrofes como quadras, sextilhas, sétimas e décimas, a literatura popular ou de cordel (ou de folhetos) é uma ferramenta pedagógica muito rica para os alunos da EJA, seja para o aprendizado sobre a cultura popular brasileira ou para o desenvolvimento da percepção estética dessa manifestação importantíssima na construção cultural do Brasil.
Memória e patrimônio na construção histórica do Instituto do Museu Jaguaribano
Authors: Farias Alex Silva
Published: April 2017

A história da cidade de Aracati remonta ao período colonial, quando desenvolveu atividade portuária, mercantil e exportadora durante a época das charqueadas. A cidade guarda toda a atmosfera de um momento da história do Ceará, por intermédio do seu conjunto arquitetônico. No município há o Instituto do Museu Jaguaribano, que nasceu do interesse de um grupo de aracatienses empenhados no enaltecimento da história da cidade e preocupados tanto com o comércio ilegal dos bens históricos da região como com a sua dilapidação. Então qual era a representação de patrimônio no discurso desses sujeitos sociais durante a construção do Museu Jaguaribano? É necessário perceber a influência do pensamento dos sujeitos sociais em um determinado momento de uma instituição de perpetuação da história local.
Entre bombardeios noticiados e fofocas impressas: euforia e práticas na imprensa escrita de Joinville – SC (1910-1960)
Authors: Kalb Christiane Heloisa
Published: April 2017

Este estudo tem o intuito de descrever, mediante uma discussãointerdisciplinar, algumas experiências vividas e os acontecimentos ocorridos na cidade de Joinville, com base em jornais impressos, tomando como pano de fundo o edifício do Cine Palácio, antigo Theatro Nicodemus, tombado em 2003, e o seu entorno desde a sua inauguração em 1917 até meados da década de 1960, quando se iniciaram os primeiros passos para o surgimento de políticas públicas de preservação na cidade. Para tanto, por meio de uma pesquisa documental no Arquivo Histórico de Joinville no período de abril a agosto de 2015, acessaram-se jornais publicados naquelasdeterminadas décadas e períodos específicos, num recorte histórico peculiar, que faz parte de uma tese de doutoramento em Ciências Humanas da Universidade Federal de Santa Catarina, com enfoque nas políticas públicas de preservação de patrimônio cultural em Joinville (SC). A intenção deste artigo é, além de analisar o clima deeuforia, as práticas e as vivências noticiadas na imprensa escrita, em período próximo à inauguração do espaço do teatro, verificar em contraponto os acontecimentos do momento, como por exemplo a declaração de guerra do Brasil à Alemanha, a Primeira Guerra Mundial e a Campanha de Nacionalização, influenciando a cidade de Joinville.Num segundo momento buscou-se analisar as semelhanças e disparidades, durante a década de 1910, entre os jornais Kolonie-Zeitung e Actualidade, veiculados em Joinville, e na sequência os jornais A Notícia, que até hoje circula na cidade, e o Jornal de Joinville num interstício determinado entre as décadas de 1940 e 1960. Por ora, conclui-se que os fatos relatados em tais impressos influenciaram a narrativa histórica desse bem cultural, atualmente protegido pela lei de tombamento municipal.
Patrimônio histórico-cutural das Assembleias de Deus: uma análise do conceito de “presentismo” (François Hartog)
Authors: Ramos Gandra Valdinei
Published: April 2017

O artigo debruça-se sobre as recentes iniciativas das Assembleias de Deus em preservar parte de seu patrimônio histórico-cultural, particularmente criando o Centro de Estudos do Movimento Pentecostal (CEMP), juntamente com o Memorial Gunnar Vingren, ambos na sede da Casa Publicadora das Assembleias de Deus (CPAD), e o Museu Nacional da Assembleia de Deus em Belém, Pará, cidade onde se iniciou a instituição religiosa em 1911. Entre os vários aportes teóricos que ajudam a entender tal fenômeno, destacam-se os conceitos de “regime de historicidade” e “presentismo” do historiador francês François Hartog, pois se entende, a partir de pesquisas realizadas nos documentos institucionais, que as ações patrimoniais das Assembleias de Deus se devem, entre outras coisas, a um modo de lidar com o tempo. Se antes passado, presente e futuro se conjugavam em chave hermenêutica escatológica, na atualidade percebe-se um arrefecimento de tal compreensão, ajustando-se institucionalmente a um “regime de historicidade presentista”, onde se estreita a relação com passado e futuro a partir do presente. O desejo de controlar as narrativas históricas, nos processos de patrimonialização da memória institucional, aponta para uma diminuição da expectativa escatológica, ou melhor, a escatologia se “presentifica”.
A construção do patrimônio cultural na realidade das interações via internet com base no paradigma intersubjetivo de Habermas
Authors: Fontana Volmir Fontana , Westphal Euler Renato Westphal , Carelli Mariluci Neis Carelli
Published: April 2017

As relações sociais no mundo atual são definidas não somente peloaprisionamento delas na objetividade do mundo, como também pelas interações, que recebem configuração de transmissão de informação ao acontecerem via internet. Essa dimensão da comunicação não caracteriza a interação necessária à formação da coletividade determinante para a construção do patrimônio cultural. Desse modo, objetivou-se estudar como o paradigma intersubjetivo de Habermas contribui para a construção do patrimônio cultural. Este é resultado da construção coletiva e tem sua expressão nas relações pensadas pelo autor, pois é formado pelas relações de alteridade entre sujeitos livres e que reconhecem a cultura e o contexto em que estão e a que pertencem suas experiências do cotidiano.

Authors: Segura Jiménez Alexis , Cambronero Molina César , Moya Castro Diego , Ledezma Cordero Luis , Loaiza Santiago
Published: April 2017

Esta investigación consta de una revisión sobre la socialización, el capital cultural y social, y la innovación en los procesos educativos; así como de su respectivo trabajo experimental, para analizar y contrastar dichos temas en el contexto educativo costarricense. El objetivo fue analizar los procesos de socialización, de capital social y cultural que poseen estudiantes innovadores de escuelas y colegios, durante el segundo ciclo del año 2014 y el primero del año 2015. Se realizó una investigación de tipo cualitativo mediante el uso de historias de vida. Se encontró que el estudiante innovador proviene de familias en donde el desarrollo del espacio intelectual es muy incentivado. También que sus familiares son muy influyentes y se definen  como principales mentores de los entrevistados. Se caracterizó el capital social, y se distinguieron capitales sociales densos e influyentes y capitales de menor tamaño, pero sólidos y de calidad o intensidad. Se determinaron las fuentes de capital cultural. Se encontró  gran variedad de elementos tales como la escuela, la familia, actividades sociales, artísticas, recreativas, hábitos cotidianos, libros, entre otros. Se evidenció la ausencia de una metodología específica en el sistema educativo que promueva las innovaciones, labor que recae en los docentes. De este punto sobresale la principal conclusión acerca de la carencia en el sistema educativo costarricense de identificar, comprender y explicar los procesos y las prácticas innovadoras.

Cementogenesis is inhibited under a mechanical static compressive force via Piezo1
Authors: Zhang Ying-ying , Huang Yi-ping , Zhao Hua-xiang , Zhang Ting , Chen Feng , Liu Yan
Published: April 2017

Objective:

To investigate whether Piezo1, a mechanotransduction gene mediates the cementogenic activity of cementoblasts under a static mechanical compressive force.

Materials and Methods:

Murine cementoblasts (OCCM-30) were exposed to a 2.0 g/cm2 static compressive force for 3, 6, 12, and 24 hours. Then the expression profile of Piezo1 and the cementogenic activity markers osteoprotegerin (Opg), osteopontin (Opn), osteocalcin (Oc), and protein tyrosine phosphataselike member A (Ptpla) were analyzed. Opg, Opn, Oc, and Ptpla expression was further measured after using siRNA to knock down Piezo1. Real-time PCR, Western blot, and cell proliferation assays were performed according to standard procedures.

Results:

After mechanical stimulation, cell morphology and proliferation did not change significantly. The expression of Piezo1, Opg, Opn, Oc, and Ptpla was significantly decreased, with a high positive correlation between Opg and Piezo1 expression. After Piezo1 knockdown, the expression of Opg, Opn, Oc, and Ptpla was further decreased under mechanical stimulation.

Conclusions:

Cementogenic activity was inhibited in OCCM-30 cells under static mechanical force, a process that was partially mediated by the decrease of Piezo1. This study provides a new viewpoint of the pathogenesis mechanism of orthodontically induced root resorption and repair.

Reluctance of Acehnese youth to use Acehnese
Authors: Al-Auwal Teuku Muhammad Ridha
Published: April 2017

This study was aimed at finding the main factors causing Acehnese youth to be reluctant to use their Acehnese language within their groups and in daily life and also at finding out their attitudes towards the Acehnese language. The study adopted a case study approach using semi-structured interviews to obtain data. Ten (10) participants, who were members of the Students Union of Syiah Kuala University, the so-called PEMA Unsyiah, who were considered representative of all the students, took part in this study. The findings revealed that negative attitudes to their Acehnese language have mushroomed amongst Acehnese youth today. Acehnese youth are now accustomed to using Indonesian instead of Acehnese language in their everyday life due to several reasons, namely: Indonesian seems more modern (showing the person to be upper- class), they feel spoken Acehnese sounds ‘harsh’ and ‘weird’, Indonesian is predominant on campus now, Indonesian seems more prestigious and ‘cooler’, Indonesian can be used to neutralize the differences between different Acehnese dialects and languages, Indonesian is more convenient whilst Acehnese is more difficult, Acehnese is mainly used for making jokes, humour and puns, Indonesian is more reasonable and convenient to communicate with the opposite sex, if communication is already running in Indonesian, it is difficult to switch it to Acehnese, and finally, Indonesian is easier and more convenient to use to greet new friends.

Published: April 2017

The advantages of ratooning rice are to save water, cost production, labor, preparation time for planting and harvesting, but the ratooning productivity is still low.  This research aimed to study the effect of the bioinsecticide and compost extract on ratooning rice production and insect populations. The ratooning rice was applied by bioinsecticide, compost extract, and combination of bioinsecticide and compost extract with dose 2 L ha-1  per application, respectively. Data of agronomic variables were statistically analyzed using analysis of variance, whereas insect pest population data were analyzed using Chi Square test. The seedling height of ratoon applied by compost extract was the highest among treatments. The number of productive tillers per clumps and rice production on plot applied by compost extract were higher than the insecticide treatment. At the age of 17 day-ratooning rice, application bioinsecticide reduced the population of insect pests, such as Ciccadulina bipunctata, Recilia dorsalis, Nilaparvata lugens, and Nephotettix nigropictus. Thus, application of compost extract tended to improved the growth and production of the ratooning rice, while the bioinsecticide decreased the insect pest population.

Published: April 2017

Pedigree selection is a method of selection used in segregating populations which takes the expertise of breeders in achieving the desired goal. This method is implemented on the early generations with a high degree of segregation and is generally performed on highly heritable traits. The purpose of this research was to study the performance of F3 generation segregants and to estimate the genetic parameters to be used for identification and selection of wheat segregants under optimum environmental condition. The research was carried out at the experiment field of  Research Institute for Ornamental Crops, in Cipanas from May to September 2012. Genetic material used were 58 F3 family and six check varieties, namely  Dewata, Selayar, Oasis, Rabe, Basribey, and HP 1744. The experiment used an augmented design. Results of analysis of variance showed that the family effect was significant for days to flowering, days to harvest, percentage of empty florets, number of grains per panicle, grain weight per panicle, number of seeds per plant and seed weight per plant. High heritability estimates were  found in days to flowering, days to harvest, seed filling period, percentage of empty florets, number of grains per panicle, grain weight per panicle, number of seeds per plant, and seed weight per plant. These characters are suitable for yield improvement of tropical highland wheat due to its high heritability values. The mean value of F3 generation changes subsequent to selection either based on grain weight per plant, or based on  number of productive tillers,  number of grain per panicle, and grain weight per plant.

Published: April 2017

Seedless fruit is one of the criteria (necessary) to improve the quality of Simadu tangerine. The most effective method to obtain seedless triploid cultivars is hybridisation between tetraploid and diploid parents. Simadu tangerine is a diploid plant. Tetraploid Simadu tangerine can be obtained with doubling chromosome using colchicines.The aim of this research was to obtain tetraploid Simadu tangerine shoot which would serve as parent to produced seedless Simadu tangerine. Shoot-tips of Simadu tangerine without leaves were treated with colchicines at four different concentrations (0, 0.1, 0.2, and 0.3%) for 3 hours. The results showed that the high concentration of 0.3% reduced survival rate. The colchicine treatments reduced growth of shoot-tip of Simadu Tangerine.The leaves of colchicines treated shoots were thicker than control. Leaves from control (0% colchicine) and 0.1% colchicine treated shoots had 8.67 and 18.25 chloroplast per pair of guard cells. Compared to those of control, leaves with 0.1% colchicine had lower stomatal density, and larger stomatal size. It appeared that 0.1% colchicine treatment resulted in tetraploid Simadu Tangerine Shoot.

Mexican sunflower (Tithonia diversifolia) is a invansive weed but it can be used as continuous and on-farm source of nutrient for organic farming system. The objective of this study was to investigate growth and biomass production of T. diversifolia with different rates of chicken manure and plant spacings. The experiment was conducted at Cikarawang, Bogor, on Inceptisol soil type, from October 2011 until January 2012. The experiment was arranged in a randomized block design with 2 factors and 3 replications. The rates of chicken manure were  0, 2.5, 5 and 10 ton ha-1, while the plant spacings were 50 cm x 50 cm and 75 cm x 75 cm. The interaction effect between manure rates and plant spacing was significant on nett assimilation rate at 4-8 weeks after planting, but it was not significant on biomass production. The highest dry weight of biomass (1,129.1 kg ha-1) was obtained from the addition of 10 ton chicken manure ha-1 with the potential contribution as much as 55.47 kg N, 4.54 kg P, 88.54 kg K per hectare. The highest dry weight of biomass produced with planting distance 50 cm x 50 cm (897 kg ha-1). Referring to the results, it can be recommended that the cultivation of T. diversifolia at the first planting needs 10 ton chicken manure ha-1 and the planting distance of 50 cm x 50 cm.

ABSTRACT

The chili consists of several species, five of which have been cultivated, namely C. annuum, C. chinense, C. frutescens, C. baccatum, and C. pubescens. The classifications of these species are based on: 1) morphological characters, especially floral morphology, 2) crossability between species, and 3) fertile hybrids between species. Species C. baccatum and C. pubescens can be easily identified and distinguished from one another, because there are obvious differences in the two species. However the species C. annuum, C. chinense, and C. frutescens has many common characteristics, so it is difficult to distinguish morphologically. The purpose of this study was to identify capsicum species based on crossability and morphological characters. The crossability experiment was done in housing area TDP 2 Ciampea Bogor from January to December 2013 and the morphological characteristics at Leuwikopo experimental station, IPB. The morphological characters experiment was arranged in randomized complete block design (RCBD) with three replications. Data were collected on successful crosses, seed viability of successful crosses and morphological characters based on descriptor for capsicum IPGRI. The percentage of successful crosses involving IPBC10 and IPBC145 (C. annuum) as female parents and 20 genotypes as male parents ranged between 0-90%; and using IPBC295 (C. frutescens) as female parent was 40%. Genotypes which had successful results equals 40% were alleged as C. frutescens species (IPBC61, IPBC139, IPBC63, IPBC163, IPBC289, IPBC288, IPBC294 and IPBC285). Principal component and of clusters analysis suggests that there are two species groups, i.e. C. annuum and C. frutescens.

ABSTRACT

Effort to increase productivity and other elite characters in Indonesia oil palm breeding program is facing a problem because of the narrow genetic diversity. To broaden the genetic diversity, germplasm exploration has been done in Angola, Central Africa. The objective of this research was to assess the genetic diversity and population structure of Angola originated oil palm germplasm based on 20 SSR markers. The plant materials used were 27 accessions consisted of 136 palms planted in Riau, Sumatera. The DNA was isolated and amplified using PCR. Phylogeny analysis was constructed using Unrooted Neighbor-Joining by DARwin software 6.0.8. The result showed that polymorphic information content (PIC) value is 0.55 (0.17 to 0.75 for each locus) with 102 total number of alleles. Genetic diversity between individuals was higher compared to the genetic diversity within accessions or regions and between accessions or regions. Phylogenetic analysis of 27 accessions showed that accessions were divided into three main groups. Every group containing individuals originated from 5 spatial distribution regions. Principal coordinates analysis (PCoA) showed that accessions were distributed in one structure. Using more primers and samples to get more representative data is recommended for the following research.

ABSTRACT

Bambara groundnut is considered tolerant to drought and unfertile soil; therefore, has higher potential to be cultivated. The average yield of dry pod weight from agricultural fields in Indonesia is still low (< 4 ton ha-1); hence, the cultivation technique must be improved. Fertilizer is the main input to increase yield of Bambara groundnut, but the optimum rates of N, P, and K have not been determined. Therefore, the objectives of the research were to determine the optimum rate of N, P, and K fertilizer for Bambara groundnut production. Three parallel experiments were conducted at Cikarawang Experimental State, Dramaga, Bogor from March to July 2013. Each experiment tested different rates of N or P or K fertilizer with compeletely randomized block design and three replications. The fertilizer rates were 0, 50, 100, 150, and 200% of recommendation rate (100% N = 100 kg Urea ha-1, 100% P = 150 kg SP-36 ha-1, 100% K = 75 kg KCl ha-1). The results showed that leaf P content increased linearly with N fertilizer application. Leaf N content linearly decreased with P fertilizer application. Leaf P content and shoot dry weight quadratically increased with K fertilizer application. The optimum rates of N and P fertilizer was unable to be determined due to insignificant response of several variables. Optimum rate of K fertilizer ranged 86.4-118.95 kg KCl ha-1.

ABSTRACT

Sago palm is a carbohydrate source which has the highest carbohydrate content compared to the other crops. It can produce about 200-400 kg per trunk of sago dry starch. More than 50% sago palm population in the world are grown in Indonesia and 90% sago palm in Indonesia is found in Papua. This research was aimed to characterize several sago palm accessions in South Sorong District, West Papua. There were 12 accessions observed, i.e. Fasai, Fasampe, Falia, Fanomik, Fasongka, Fafion, Fakattao, Fanke, Fablen, Failik, Fakreit and Fasinan. Among these accessions, there were many differences based on morphological characteristics such as shoots color, crown shape, trunk height, number of leaf, existence of spine, starch content, also pith and starch color. Fablen was the only non-spiny type. Most of sago accessions were high yielding accessions with the potential yield more than 200 kg per trunk of sago dry starch. Fanomik had the highest potential yield. Sago palm productivity in the natural forest of Saifi Subdistrict, South Sorong District, West Papua was estimated to reach approximately 34.59 ton ha-1 per year of sago dry starch.

ABSTRACT

Drought has become a main barrier of rainfed rice in dry climate and short wet season areas. Growing drought-tolerance varieties is a practical approach to minimize yield lost of rice by the drought stress condition. The aims of this research were to examine the inheritance of drought tolerance character, to identify selection traits, and to estimate genetic gain for drought tolerant on lowland rice. Four rice varieties, i.e., Jatiluhur, Mentik Wangi, IR64, Way Apo Buru, were fully diallel crossed. The parent varieties and the F1’s were grown at Sawah Baru, Dramaga experimental field in two irrigation treatments, optimum and sub optimum where irrigation was applied until three weeks after transplanting. A randomized complete block design with three replications for each irrigation treatment was applied to the experiment. The results showed that there is a significant maternal effect on tiller number. The values of additive variance were higher than the dominance for all other characters except tiller number and grain weight per plant. The highest value for narrow sense heritability was achieved by panicle length.

ABSTRACT

Hybrid rice varieties  is an alternative technology to improve  productivity of low land rice. The results of previous studies have identified and found the male sterile lines Wild Abortive type and Kalinga are resistant to bacterial leaf blight pathotype III, IV and VIII. The objectives of the research were to obtain information on agronomic characters, yield evaluation, genetic parameters, and repeatability information. The experiment was conducted in two locations namely  Muara and Indramayu experimental stations. The design used was a Randomized Complete Block Design with three replication at each site.  Each replicate consisted of 17 hybrid rice and three check varieties. The results from locations showed that genotype BI485A/BP1 (IR53942) has the highest yield of 5.8 ton ha-1. The coefficient of genetic and phenotypic diversity of six agronomic characters was low. The repeatability for seven character observed were low, except for days to flowering.

ABSTRACT

Weeds has become a big problem in system of rice intensification (SRI), integrated crop management (ICM) and conventional cultivation systems. The objective of the research was to study the dominancy and potential of harmful effect of weed in these three cultivation systems. The research was conducted at Sukamandi research station of Indonesian Center for Rice Research, Subang, from November 2013 to April 2014 during rainy season. The experiment was arranged in a split plot design with four replications. The cultivation systems was main plot consisted of system of rice intensification (SRI), integrated crop management (ICM) and conventional system. The weeding techniques as subplot consisted of no weeding, manual weeding, mechanical weeding and chemical weeding. The result showed that based on dry mass of weeds the highest risk of weed was exhibited at SRI with total dry mass of weed 51.53 g m-2 (0.5 ton ha-1) and the lowest was at conventional system with 32.45 g m-2 (0.3 ton ha-1). Proper weed control increased rice production by 28.9% for SRI, by 29.4% for ICM and by 14.6% for conventional cultivation systems.

ABSTRACT

Bambara groundnut (Vigna subterranea L. Verdc.) is an important underutilized legume crop in Indonesia. The aim of this research is to study genetic diversity of bambara groundnut from Sukabumi and Sumedang, West Java, Indonesia. This study used 107 bambara groundnut accessions, which consisted of 57 accessions from Sukabumi and 50 accessions from Sumedang. We use five simple sequence repeat (SSR) to analyze the accessions. Totally nine alleles were detected, with a mean of 1.8 alleles per locus. Allelic and gene diversities were higher in Sumedang (1.8 alleles per locus and 0.119) than in Sukabumi population (1.4 alleles per locus and 0.020), respectively. We constructed a phylogenic tree by Neighbor-Joining analysis based on genetic distances (DA) and showed the tree divided bambara groundnut accessions into two broad groups according to the origin of samples (Sukabumi and Sumedang). Results from the phylogenic tree are in line with those from the population structure analysis.

ABSTRACT

Sugarcane cultivars tolerant to drought stress are needed for specific location. In vitro selection can be used to obtain plants tolerant to drought stress through regeneration of callus in the culture medium. The purpose of this study was to obtain regenerants from irradiated callus on the stress medium. The experimental design was a completely randomized design with two factors. The first factor was the regeneration medium (RG) added with PEG 6000, i.e., 0%, 5%, 10% and 15%, while the second factor was the dose of gamma ray irradiation i.e. 0 krad, 5 and 10 krad, and 15 krad. There were 12 treatments, each treatment was repeated 18 times and each repetition was a culture bottles planted with three clums of callus 10 mm diameter. RG medium was the MS medium added with 0.5 mg L-1 BAP, Kinetin 0.1 mg L-1 and IBA 1.0 mg L-1. The higher the concentration of PEG, the less regenerants were produced. Regenerants could be generated from the selection medium PEG up to 15%. Several shoots still produced from callus irradiated with 10 krad. Selection medium with PEG up to 10% decreased the precentage of albino regenerants. The gamma ray irradiation dose and the concentration of PEG significanly affected the number of  roots produced.

Situs Liang Ulin 2 yang berada di kawasan karst Mantewe, Kabupaten Tanah Bumbu, Kalimantan Selatan adalah salah satu gua hunian dari masa prasejarah. Data arkeologi yang berupa pecahan gerabah, alat tulang, dan artefak batu serta himpunan tulang binatang dan cangkang kerang adalah bagian dari aktivitas kehidupan manusia. Peralatan yang dihasilkan merupakan bentuk respon manusia untuk pemenuhan kebutuhan hidup yang paling dasar, antara lain pangan, sandang, dan papan. Sementara itu, keberadaan artefak batu di Liang Ulin 2 yang belum dibahas sebelumnya memunculkan permasalahan terkait dengan tipologi dan teknologi serta argumen fungsinya. Metode yang digunakan untuk menentukan tipologi adalah klasifikasi yang menghasilkan terminologi tiap kelompok yang terbentuk. Klasifikasi yang disusun berhasil menggolongkan artefak batu Liang Ulin 2 menjadi dua kelompok besar, yaitu alat dan bukan alat. Kelompok alat yang terdiri atas batu inti dan serpih dengan retus diketahui tidak memiliki bentuk dan fungsi tertentu. Alat serpih dibuat untuk fungsi praktis dalam rangka pemenuhan kebutuhan hidup. Sementara itu, kelompok bukan alat yang terdiri atas serpih proksimal, fragmen serpih, dan tatal adalah hasil dari pangkasan dalam proses pembuatan alat yang tidak digunakan
Interpretation of uncommon ECG findings in patients with atrial flutter
Authors: Sorokivskyy Mykhaylo , Chernyaha-Royko Ulyana
Published: April 2017

In this article, several uncommon cases of different atrial flutter (AFL) types are described. Electrocardiogram (ECG), the standard and widespread method of rhythm disturbances detection, sometimes can be insufficient for correct diagnosis in such cases. Different features of atrioventricular (AV) conduction and multiple atrial macro re-entry circles may considerably influence the surface ECG. Another distorting factor of AFL appearance is possibility of ECG elements superposition and overlapping. Some atypical forms of AFL can be poorly visible and sometimes cannot be  differentiated from other types of supraventricular arrhythmias on surface 12-lead ECG.
Arbeitszeiten von Vätern: Welche Rolle spielen betriebskulturelle und betriebsstrukturelle Rahmenbedingungen?

Published: April 2017

Many fathers would like to work less, but they do not reduce their working hours. Studies on the role of workplace organizations for work-family balance point to adverse working conditions as a major obstacle. Quantitative studies, however, are still rare due to the lack of data resources. This paper uses an AID:A add-on survey of 878 parenting couples from 2015 to study the relationships between cultural and structural workplace conditions and fathers’ working times. We differentiate between part-time work, contractual and actual working hours. The results show a robust relationship between fathers’ inclination to work reduced hours and the extent to which formal, universal and transparent policies exist in their workplaces. Perceptions of a strong ideal-worker norm and a supportive culture of temporary replacement are particularly relevant for whether fathers manage to comply with their contractual working hours. Surprisingly, fathers tend to have longer contractual hours, the more they feel supported by their supervisors. The results also indicate that cultural workplace conditions that support shorter working hours of fathers can be found in many economic sectors and companies of different sizes.

Zusammenfassung

Viele Väter wünschen sich kürzere Arbeitszeiten, setzen diesen Wunsch jedoch nicht um. Studien zur Rolle von Arbeitsorganisationen für die Vereinbarkeit von Familie und Beruf lassen ungünstige betriebliche Rahmenbedingungen als einen wichtigen Hinderungsgrund vermuten. Quantitative Studien stehen mangels Datengrundlage jedoch bislang weitgehend aus. Basierend auf einer AID:A-Zusatzbefragung von 878 Elternpaaren aus dem Jahr 2015 untersucht dieser Beitrag Zusammenhänge zwischen betriebskulturellen und -strukturellen Faktoren und den Arbeitszeiten von Vätern. Dabei differenzieren wir zwischen Teilzeitarbeit, vertraglichen und tatsächlichen Arbeitszeiten. Die Ergebnisse zeigen einen robusten Zusammenhang zwischen dem Ausmaß an formellen, allgemeingültigen und transparenten Regelungen im Betrieb und kürzeren Arbeitszeiten von Vätern. Verfügbarkeits- und Vertretungskulturen sind offenbar besonders dafür relevant, ob vertragliche Arbeitszeiten auch eingehalten werden. Überraschend haben Väter umso längere vertragliche Arbeitszeiten, je stärker sie sich von ihren Vorgesetzten unterstützt fühlen. Die Ergebnisse weisen auch darauf hin, dass günstige kulturelle Rahmenbedingungen für kürzere Arbeitszeiten von Vätern in vielen Branchen und Betrieben unterschiedlicher Größe möglich sind.

This cross sectional descriptive study was conducted among the health policy makers, health administrators, doctors including medical teachers, intern doctors, clinically exposed medical students and patients. The study was conducted at government and non government medical colleges of Dhaka and outside Dhaka from 1st July 2014 to 30th June 2015. Total respondents were 372 and information was collected through in-depth interview schedule and self administered semi structured questionnaire. The qualitative information was collected from health policy makers including administrators by in-depth interview which was complimentary to the findings obtained by self administered semi structured questionnaire. Out of 372 respondents 280 (75.3%) and 92 (24.7%) were engaged in government and non- government hospitals/ organizations respectively. Among the respondents 164 (44.1%) agreed and 98 (26.3%) strongly agreed that introduction of licensing examination for the medical and dental practitioners are justified in the present context of Bangladesh. Of the total, 294 (79%) agreed and 40 (10.8%) strongly agreed that licensing examination shall be useful for individual professional development and also agreed that this will help in overall professional development, shall improvement of professional competency and shall enrich doctors with updated professional knowledge. Majority of the respondents (70.6%) mentioned that doctors may not be interested. Of the same respondents 99.1% opined that the registration shall be on the basis of degree or the examination shall only be for person graduated from abroad or foreigner graduates. About 73% respondents were in agreement with 5 years validity period for an examination. Of the total 84.4% respondents agreed that the examination will improvement of standard of medical and dental education offered by all medical and dental colleges of Bangladesh. There are many direct and indirect benefits of introducing licensing examination for the registration of medical and dental graduates/practitioners and there are a few barriers to implement that too.Bangladesh Journal of Medical Education Vol.8(1) 2017: 2-8
