Published: January 2020

Radiasi matahari menghasilkan kalor sebagai sumber energi yang dapat dikumpulkan menjadi satu titik sehingga mampu untuk memasak air menggunakan alat bernama Reflektor cermin parabolic. Untuk memperbesar perpindahan kalor menyeluruh (Qm) maka dipilih bahan reflector yang mudah memantulkan sinar matahari. Tujuan yang dilakukan pada penelitian ini adalah untuk mengetahui daya dan efisiensi termal kolektor pada kompor tenaga surya. Metodologi penelitian ini dengan cara pengambilan data dengan parameter waktu yang sudah ditentukan sesuai kondisi lingkungan untuk memanaskan air 1000 gram. Subyek penelitian ini adalah parabolic solar cooker dengan diameter 84 cm. Hasil daya kompor yang diperoleh sebesar 36,59 Watt dan efisiensi termal kompor sebesar 6,18 %. Daya kompor dipengaruhi oleh selisih temperatur air setelah dipanaskan dengan temperatur air sebelum dipanaskan. Semakin besar temperatur air setelah dipanaskan maka akan memperbesar daya kompor tersebut. Semakin besar perpindahan kalor menyeluruh Qm dan semakin kecil intensitas radiasi matahari pada reflector yang menggunakan cermin maka efisiensi termal semakin besar.Kata kunci: kompor parabola tenaga surya, daya kompor, efisiensi termalABSTRACTSolar radiation generates the heat as a source of energy that can be collected into a single point so that it is able to cook water using a tool named mirror parabolic reflector. To enlarge the whole heat transfer (QM) then selected reflector material that easily reflects the sunlight. The purpose of this study is to find out the power and efficiency of thermal collectors on solar power stoves. This research methodology by means of data retrieval with specified time parameters according to environmental conditions to heat water 1000 grams. The subject of this study is the parabolic solar cooker with a diameter of 84 cm. Results of stove Power obtained at 36.59 Watt and thermal efficiency of the stove amounted to 6.18%. The cooker's power is influenced by the water temperature difference after heated with water temperature before heated. The larger the water temperature after heated it will enlarge the stove's power. The larger the overall heat transfer of the Qm and the smaller the intensity of the solar radiation on the reflector using the mirror hence the greater the thermal efficiency.

Published: January 2020

Background. Everyday medical residents experience stress related to academic, professional, and personal factors (Alosaimi, Alghamdi, Aladwani, Kazim, & Almufleh, 2016; Dave, Parikh, Vankar, & Valipay, 2018), therefore it is important to take care of their psychosocial well-being. Traits of medical residents that are important for well-being are related to control of emotional information, and abilities that provide for effective handling of stressful situations are important as well. The objective of the present study was to assess correlations between emotional intelligence and stress coping strategies of medical residents. Methods. The study sample consisted of medical residents (n = 108). The following questionnaires were used: TEIQue-SF and Coping Styles Questionnaire. Questionnaires were sent to personal electronic addresses and target groups of social networks. Paper-based questionnaires were presented in the work and gathering places of subjects.Results. Emotional intelligence was higher than average, and the most expressed trait was the overall sense of well-being (in relation to emotionality, self-control and sociability). Sociability and self-control were more expressed in men than in women. Rational coping with stress was the most characteristic for medical residents (in relation to emotional coping, detached and avoidance coping). Women were more than men inclined to use emotional coping while men were more inclined than women to use detached coping.Conclusions. Statistically significant correlation existed between emotional intelligence and stress coping strategies of medical residents. Positive correlation was determined between emotional intelligence and adaptive stress coping strategies, while negative correlation was observed between emotional intelligence and maladaptive stress coping strategies. Keywords: resident doctors, stress, emotional intelligence as a trait, coping with stress.

Published: January 2020

Background. The behaviour of physical education (PE) teachers in managing the lesson is significantly related to their life satisfaction (Bahadir, 2013). PE teachers’ self-report of emotional abilities is positively associated with the educational achievements of their students and increasing teachers’ self-report of emotional abilities improves the quality of physical education (Buns & Thomas, 2016). High self-report of emotional abilities reduces the impact of work-related stress on teachers, increases their creativity in classroom activities and increases students' satisfaction with physical activities (Huang, Liu, Hsieh, & Chang, 2015). The aim of this study was to evaluate physical education teachers’ self-report of emotional abilities and subjective quality of life in comparison with teachers of other subjects, so that in the future more effective measures for improving teachers’ self-report of emotional abilities and subjective quality of life could be developed.Methods. To collect data, Schutte SSRI and SF-36 questionnaire survey was applied.Results. We found that, according to some sub-scales, men and women were significantly (p < .05) different in the estimation of their subjective quality of life. Women scored better (higher scores) than men in their physical performance, emotional state, energy/fatigue, and perceived pain. In this study, we revealed significant correlations between social skills and appraisal (r = .305, p < .01), emotional well-being and appraisal (r = .214; p < .05), and energy/fatigue and appraisal (r = .209; p < .05). The data obtained in our study revealed that male and female teachers evaluated their ability to understand and analyze emotions and manage emotions differently (p < .05).Conclusions. Teachers’ self-report of emotional abilities differed significantly by appraisal and utilization and by the subject taught, which differed in optimism, appraisal, and utilization. Significant (p < .05) differences in subjective quality of life were found by gender in to physical functioning, emotional well-being, energy/fatigue, and pain. There was no significant difference found in subjective quality of life by the subject taught.Keywords: physical education, teacher, self-report of emotional abilities, subjective quality of life.

Conceptually, multiculturalism refers to country profile as a plural nation and multicultural society. Citizens would appreciate plurality and multiculturalism based on the equity principle.Multiculturalism as a concept of diversity and equity should be accomodated in the national education system. It should be reflected in the curriculum. Besides, the school has opportunity to develop its school curriculum (KTSP) integrating multicultural elements.Citizenship Education subject has the functions to integrate and develop multiculturalism issues in selected topics such as unity, equity, human rights, democracy, justice, and law. Other subjects integrate the issues into the teaching and learning process focusing issues of gender, ethnicity, and religion. Multicultural education is intended for develoving national character which promote students interactivity of different social cultural background.

MENGEMBANGKAN PROFESIONALISME PENDIDIK GURU (Kajian Konseptual Dan Operasional)
Authors: Wardani I G. A. K. 
Published: January 2020

The role of teacher educators is becoming more and more important in fulfilling the need of profesional teachers as stated in the Indonesian Republic Law #14/2005 on Teacher and Lecturer. In order to be able to educate profesional teachers and teacher candidates, the teacher educators alone should be profesional, and have willingness to continuously develop profesionalism. Developing profesionalism is a must for teacher educators, due to four reasons: (1) the nature of profesionalism, (2) the rapid development of science, technology and arts, (3) the life-long learning paradigm, and (4) the demand of Law # 14/2005 on Teacher and Lecturer. But the data on teacher educators from several Teacher Education Institutions indicate that not all of teacher educators show willingness to develop profesionalism. Therefore, profesionalism development should be encouraged by all parties related to teachers and teacher educators. There are many activities that can be undergone by teacher educators in order to develop profesionalism, some of which are: taking further study, taking relevant courses, regular self reflection, joining academic activities (seminar, workshop, training,etc.), school familiarization, conducting research, and publishing scientific article.
Peran pendidik guru menjadi lebih dan lebih penting dalam memenuhi kebutuhan guru profesional sebagaimana tercantum dalam Undang-Undang Republik Indonesia # 14/2005 tentang Guru dan Dosen. Agar dapat mendidik guru profesional dan calon guru, pendidik guru sendiri harus profesional, dan memiliki kemauan untuk terus mengembangkan profesionalisme. Mengembangkan profesionalisme adalah suatu keharusan bagi pendidik guru, karena empat alasan: (1) sifat profesionalisme, (2) perkembangan pesat ilmu pengetahuan, teknologi dan seni, (3) paradigma pembelajaran seumur hidup, dan (4) permintaan Hukum # 14/2005 tentang Guru dan Dosen. Namun data pada pendidik guru dari Lembaga Pendidikan Guru beberapa menunjukkan bahwa tidak semua pendidik guru menunjukkan kesediaan untuk mengembangkan profesionalisme. Oleh karena itu, pengembangan profesionalisme harus didorong oleh semua pihak yang terkait dengan guru dan pendidik guru. Ada banyak kegiatan yang dapat dialami oleh pendidik guru dalam rangka mengembangkan profesionalisme, beberapa diantaranya adalah: mengambil studi lebih lanjut, mengambil kursus yang relevan, refleksi diri secara teratur, bergabung dengan kegiatan akademik (seminar, lokakarya, pelatihan, dll), pengenalan sekolah , melakukan penelitian, dan penerbitan artikel ilmiah.

Early Mortality of Prostatectomy vs. Radiotherapy as a Primary Treatment for Prostate Cancer: A Population-Based Study From the United States and East Germany
Authors: Medenwald Daniel , Vordermark Dirk , Dietzel Christian T. 
Published: January 2020

Objective: To assess the extent of early mortality and its temporal course after prostatectomy and radiotherapy in the general population.Methods: Data from the Surveillance, Epidemiology, and End Results (SEER) database and East German epidemiologic cancer registries were used for the years 2005–2013. Metastasized cases were excluded. Analyzing overall mortality, year-specific Cox regression models were used after adjusting for age (including age squared), risk stage, and grading. To estimate temporal hazards, we computed year-specific conditional hazards for surgery and radiotherapy after propensity-score matching and applied piecewise proportional hazard models.Results: In German and US populations, we observed higher initial 3-month mortality odds for prostatectomy (USA: 9.4, 95% CI: 7.8–11.2; Germany: 9.1, 95% CI: 5.1–16.2) approaching the null effect value not before 24-months (estimated annual mean 36-months in US data) after diagnosis. During the observational period, we observed a constant hazard ratio for the 24-month mortality in the US population (2005: 1.7, 95% CI: 1.5–1.9; 2013: 1.9, 95% CI: 1.6–2.2) comparing surgery and radiotherapy. The same was true in the German cohort (2005: 1.4, 95% CI: 0.9–2.1; 2013: 3.3, 95% CI: 2.2–5.1). Considering low-risk cases, the adverse surgery effect appeared stronger.Conclusion: There is strong evidence from two independent populations of a considerably higher early to midterm mortality after prostatectomy compared to radiotherapy extending the time of early mortality considered by previous studies up to 36-months.
Subsidio al precio del Gas Licuado de Petróleo en Bolivia
Authors: Medinaceli Monrroy Sergio Mauricio 
Published: January 2020

El presente documento analiza las consecuencias redistributivas de una posible eliminación del subsidio al precio del Gas Licuado de Petróleo (GLP) en Bolivia. A través de un procedimiento de micro simulación se estudió el cambio de comportamiento que tendrían las familias, según sea su nivel de ingreso y pobreza, ante un incremento en el precio del GLP Para alcanzar este objetivo se tomó como base de información la encuesta de hogares realizada en Bolivia a finales del año 2000.
Los resultados más importantes son: a) el consumo de GLP es característica de los hogares en el área urbana, sean éstos pobres o no; b) el impacto redistributivo que tendría la eliminación del subsidio depende de la capacidad que tengan estas familias para sustituir este energético; por tanto, a mayor sustitución menor regresividad de la medida; y c) los energéticos que presentan una mayor probabilidad de ser sustitutos del GLP son la leña y el kerosén. Otro impacto del incremento en el precio del GLP sería la recomposición de la matriz energética, privilegiando el consumo de estos dos últimos productos.
Entre la formalidad y la informalidad. ¿Opciones e ingresos diferentes?
Authors: Morales Rolando 
Published: January 2020

En base a la clasificación de los trabajadores entre dependientes e independientes (pequeños empresarios y trabajadores por cuenta propia) y entre formales e informales, se plantea en este trabajo algunas importantes interrogantes: 1) ¿Es posible identificar las características de los trabajadores que los llevan a escoger preferentemente alguna de las categorías?, 2) ¿Existen grupos de trabajadores con características similares en las diferentes categorías?, ¿en qué magnitud? 3) ¿Existen diferencias en los ingresos provenientes del trabajo en las diferentes categorías entre trabajadores con características similares? Las respuestas a estas interrogantes llevan a insertarse en el debate teórico sobre la existencia o no de segmentación en los diferentes mercados laborales. Las conclusiones son: 1) Diferentes características de los trabajadores los llevan a optar por una u otra categoría laboral, 2) Hay grupos de trabajadores con características similares entre las diferentes categorías, 3) En grupos similares, la formalización no lleva a mejorar los ingresos de los pequeños empresarios ni de los trabajadores por cuenta, pero sí de los trabajadores dependientes, 4) Algunos trabajadores se enfrentan a la segmentación por no reunir suficientes requisitos laborales, otros por la estrechez del mercado, pero muchos optan voluntariamente por su estatus laboral actual.
La evolución de la pobreza en Bolivia: un enfoque multidimensional
Authors: Villarroel Paul , Hernani-Limarino Werner L. 
Published: January 2020

Este documento construye una medida de pobreza multidimensional para Bolivia, basado en todos los derechos fundamentales establecidos en la Constitución de 2008 que pueden ser medidos en las encuestas de hogares; y documenta los cambios de pobreza observados en Bolivia durante la última década utilizando un enfoque multidimensional. En particular, extendemos el análisis de Hernani-Limarino (2010) de la evolución de la pobreza monetaria con nuevas mediciones de líneas de pobreza desarrollados por Hernani y Eid (2013) y un análisis que incorpora cinco dimensiones no monetarias: acceso a educación, seguridad social de corto plazo (salud), seguridad social de largo plazo (pensiones), vivienda adecuada, y servicios básicos de la vivienda (electricidad, agua, saneamiento básico y telecomunicaciones). El análisis muestra que, durante el periodo 1999-2011, la pobreza monetaria ha mostrado una tendencia decreciente acelerada a partir del año 2005, con una tasa de reducción promedio de 4.5% anual, que representa 253,364 personas por año. Por otra parte, se han observado ligeros avances en el acceso a dimensiones sociales durante el periodo 1999-2005 en el área urbana, mientras que en el área rural se han mantenido niveles altos de privación. Estos resultados han generado que la pobreza multidimensional se haya reducido en 24 puntos porcentuales durante el periodo 1999-2011 pero también un aumento de las personas con vulnerabilidad social por el comportamiento elusivo de la pobreza no monetaria en el país.
