Published: February 2022

Abstrak: Hasil penelitian menunjukkan bahwa kombinasi aplikasi ekstrak kulit jengkol dan ekstrak umbi gadung racun berpengaruh terhadap penghambatan makan, waktu kematian dan mortalitas keong mas. Persentase penghambatan makan tertinggi terdapat pada perlakuan J3G3 rata-rata 3,77%. Aktifitas makan keong mas mengalami penghambatan karena peran senyawa alkaloid pada ekstrak kulit jengkol yang bersifat racun perut bersinergi dengan senyawa HCN yang membuat metabolisme keong mas terganggu. Waktu kematian tertinggi terdapat pada perlakuan J3G3 dengan jumlah kematian 10 ekor. Kecepatan kematian keong mas sangat ditentukan oleh tingginya kandungan senyawa toksik yang terdapat pada berbagai perlakuan konsentrasi ekstrak kulit jengkol dan umbi gadung racun, dimana semakin tinggi kandungan senyawa toksik yang terdapat pada ekstrak kulit jengkol dan umbi gadung racun maka kematian keong mas akan semakin cepat. Mortalitas keong mas tertinggi terdapat pada perlakuan J3G3 yang mencapai 100%. Tingginya mortalitas keong mas dipengaruhi oleh senyawa toksik yang terdapat pada ekstrak kulit jengkol yaitu alkaloid, steroid/triterpenoid, saponin, flavanoid dan tanin bersinergi dengan senyawa toksik yang terdapat pada umbi gadung racun yaitu dioskorin dan asam sianida.The Effect of  Jengkol Peel Extract and Gadung Tuber on the Mortality of The Golden Snail (Pomacea canaliculata LamarckAbstract. The results showed that the combination of jengkol peel extract and gadung tuber extract had an effect on feeding inhibition, time of death and mortality of golden snails. The highest percentage of food inhibition was found in the J3G3 treatment, an average of 3.77%. The activity of eating golden snails was hampered because of the role of alkaloid compounds in jengkol skin extract which is a stomach poison in synergy with HCN compounds that interfere with the metabolism of golden snails. The highest time of death was found in the J3G3 treatment with 10 deaths. The speed of death of golden snails is largely determined by the high content of toxic compounds found in various concentrations of extracts of jengkol peel and gadung tubers, where the higher the content of toxic compounds contained in the extracts of jengkol peel and gadung tubers. the faster the death of the golden snail. The highest gold snail mortality was found in the J3G3 treatment which reached 100%. The high mortality of golden snails is influenced by the toxic compounds found in the jengkol peel extract, namely alkaloids, steroids/triterpenoids, saponins, flavonoids and tannins that synergize with toxic compounds found in gadung tubers, namely dioscorin and cyanide acid.

Objetivo: Determinar los factores asociados a la no adherencia de pacientes con enfermedad coronaria al PRC (Programa de rehabilitación cardiaca) en una clínica de Cali entre 2017 y 2019.Métodos: Estudio retrospectivo de casos y controles donde se realizó un análisis bivariado y multivariado de 99 pacientes, 46 casos no se adhirieron al PRC y 56 si lo hicieron. Resultados: el 21% de los pacientes correspondieron al sexo masculino con una edad promedio de 63.2 ±10.25 años; se evidenció asociación entre la variable ansiedad evaluada con la escala HADS y la no adherencia a la PCR con una OR de 0.26 (IC 95%: 0.07-0.84; p: 0.0114). Conclusión: La presencia de ansiedad es un factor asociado en pacientes con no adherencia al PRC y por eso se considera de gran relevancia que el programa cuente con un equipo interdisciplinario. La correcta aplicación de cuestionarios como el HADS permiten identificar este tipo de situaciones a nivel personal ayudando a mejorar esta adherencia y así lograr los beneficios propuestos en el programa.

Authors: Gong Byoung-gyu , Collins Clarin , Amrein-Beardsley Audrey
Published: February 2022

The Kingdom of Saudi Arabia (KSA) recently initiated multiple, one-year, school immersion programs to help 25,000 KSA teachers better support KSA students and the KSA education system after spending time abroad in teacher education programs throughout the United States (US). This study explored the effects of one such program, aimed at helping KSA teachers become agents of change. The authors examined how the 46 KSA teachers involved in this program changed. Survey-research and English language tests were used to show that the immersion program yielded its desired effects: the program increased teachers’ sense of efficacy; improved teachers’ pedagogical, content, technical, and English language skills; and enhanced teachers’ understandings of education across nations and cultures, with emphasis on the transfer of features of the US educational system back to the KSA (although teachers were uncertain about the extent to which the transference desired might actually occur). Via supplemental interviews, the authors also identified self-reported influential sources of change. The article examines how these sources of change impacted KSA teachers’ mindsets regarding their teaching. The study confirms that the program influenced participants through their school immersion experiences, given that the program offered KSA teachers chances to learn more about student-centered learning approaches and more customized and individualized care for students.
Female Emirati Teachers’ Perceptions of Postgraduate Degree Attainment in the UAE
Authors: Yahya Khabirah
Published: February 2022

While the Emirati government continues to make great strides in encouraging female Emirati citizens to become public school teachers and educational leaders, the change process has been slow. According to the most recent data, there is a severe shortage of female Emirati postgraduates, especially in the education field, limiting qualified female Emirati leadership. The United Arab Emirates (UAE) government calls for more female leaders in all fields, including education. Despite the UAE’s attempts to encourage women to obtain a secular graduate-level education and become educational leaders, the response has been minimal. Lack of female educational leadership both inside and outside of school walls may cause more stress on the country’s education system because students may not receive adequate knowledge regarding Emirati culture and values in school. Participants felt that foreign teachers and educational leaders are unable to model or provide sufficient cultural awareness education to the students. This qualitative study was comprised of interviews with 13 female Emirati teachers who desire to obtain a postgraduate degree in education but have yet to complete the task. The study examined the female Emirati teachers’ perceptions of the factors that inhibit them from obtaining a postgraduate degree in education in Abu Dhabi. The findings show that understandings of culture and religious obligations  play a major role in the Emirati women’s decision to go to graduate school and ultimately become leaders in the country. This finding is of major importance to Emirati social and education policy contexts for continued encouragement of Emirati women to get postgraduate degrees and become leaders in the UAE.
Bazylika św. Marii Magdaleny i św. Stanisława w Szczepanowie – od gotyckiego kościoła długoszowego po dwudziestowieczny kościół podwójny
Authors: Czechowicz Jacek
Published: February 2022

Ceglano-kamienny kościół gotycki wzniesiony w 1470 roku w Szczepanowie z fundacji Jana Długosza jest interesującym przykładem przeobrażenia świątyni w kaplicę. Po neogotyckiej rozbudowie w latach 1907–1914 powstał w tym miejscu kościół w istocie podwójny, zawierający elementy zarówno spójne, jak i kontrastowe – pod względem gabarytów i stylistyki. Niniejszy artykuł zawiera charakterystykę kolejnych przemian strukturalnych tej niewielkiej pierwotnie budowli, która – znacznie powiększona na początku XX wieku – uzyskała charakter obiektu niemal katedralnego. Pomimo tak radykalnych działań szczepanowska świątynia stanowi przykład zespołu architektonicznego, w którym obydwie części – średniowieczna i neogotycka – są dla siebie wzajemnym tłem i uzupełnieniem.

Authors: Melhem Mohammad Amein
Published: February 2022

The study examined the predictive ability of self-control of academic self-handicapping among university students. The sample of the study consists of (130) students from a public university, selected randomly. To achieve the study objectives, a survey was employed to collect data. It included a self-control scale and an academic self-handicapping scale. The mean, standard deviation, t-test and multiple analysis regression were used to analyze the data. The results of the study revealed that academic self-handicapping and self-control levels among BAU students were moderate. There were no statistically significant differences in academic self-handicapping level due to gender, while there were differences in self-control level due to gender in favor of females. The results also revealed that self-control is a significant predictor of academic self-handicapping. The study recommended improving self-control especially among male students as it affects their low-level of self-handicapping.

Keywords: Academic self-handicapping; Jordanian universities; Self-control; Self-control among university students.

Paulo Freire nasceu em 1920, em Recife, Brasil. Em 1947, ele começou a trabalhar com adultos analfabetos no Nordeste do Brasil, e gradualmente aprimorou um método de trabalho com o qual a palavra conscientização* tem sido associada. Até 1964, ele era professor de História e Filosofia da Educação na Universidade de Recife e, nos anos sessenta, se envolveu em um movimento de educação popular para lidar com o analfabetismo em massa. A partir de 1962, houve ampla experimentação do seu método e o movimento estendeu-se com o apoio do Governo Federal, de modo que em 1963-64 havia cursos para coordenadores em todos os estados brasileiros e desenhou-se um plano para que 2000 Círculos de Cultura fossem estabelecidos, visando alcançar 2.000.000 de analfabetos!
Freire foi preso após o golpe de estado de 1964, em função do que a “nova ordem” considerou como elementos subversivos em seu trabalho como professor. Ele partiu em seguida para o exílio no Chile, onde seu método foi utilizado e a School of Political Sciences, da ONU, apresentou seminários sobre seu trabalho. Em 1969-70, ele foi Professor Visitante no Center for the Study of Development and Social Change, de Harvard. Em 1970 ele assumiu o posto de consultor especial no Escritório de Educação do Conselho Mundial de Igrejas, em Genebra.
Professor Freire é casado e tem cinco filhos. Seus textos incluem vários livros e artigos em português, francês, espanhol e alemão. Em inglês, a Harvard Education Review(em maio e setembro de 1970), publicou Cultural Action for Freedom e, em novembro de 1970, a Herder & Herder, em Nova York, publicou Pedagogy of the Oppressed.
