Acerca de las dificultades que tienen los profesores de secundaria para visualizar y representar objetos tridimensionales

El trabajo involucra reacciones y dificultades de los profesores de secundaria ante actividades innovadoras de geometría tridimensional, que exigen la visualización de los efectos que producen ciertos giros sobre objetos sólidos, bajo diversos ángulos, con el fin de ser representados en papel isométrico

Improving awareness about the meaning of the principle of mathematical induction

This work is based on our conviction that it is possible to minimize difficulties students face in learning the principle of mathematical induction by means of clarifying its logical aspects. Based on previous research and theory, we designed a method of fostering students’ understanding of the principle. We present results that support the effectiveness of our method with teachers in training who are not specializing in mathematics. Fomentar la conciencia sobre el significado del principio de inducción matemática Este trabajo está basado en nuestra convicción de que es posible minimizar las dificultades de los alumnos cuando se enfrentan al aprendizaje del principio de inducción matemática mediante la clarificación de sus aspectos lógicos. Basándonos en la investigación y teoría previas, diseñamos un método para fomentar la comprensión del principio por los alumnos. Presentamos resultados que respaldan la efectividad de nuestro método con profesores en formación no especializados en matemáticas.Handle: http://hdl.handle.net/10481/350

EFFECT OF THE HEAT AND SURFACE LASER TREATMENT ON THE CORROSION DEGRADATION OF THE Mg-Al ALLOYS

In this paper there is presented the corrosion behavior of the cast magnesium alloys as cast state, after heat and laser treatment. Pitting corrosion resistance of the analyzed alloys was carried out using the potentiodynamic electrochemical method (direct current), based on a anodic polarization curve. On the basis of the achieved anodic polarization curves, using the Tefel extrapolation method near to the corrosion potential, the quantitative data were determined, which describe the electrochemical corrosion process of the investigated alloys: value of the corrosion potential Ecorr (mV), polarization resistance RP (kohm.cm2), corrosion current density icorr (10-6A/cm2), corrosion rate Vcorr (mm/year) as well the mass loss Vc (g/m2<)

Analisis Faktor-faktor Yang Berhubungan Dengan Kejadian Malaria Pada Anak Di Wilayah Kerja Pkm Tona Kecamatan Tahuna Kabupaten Sangihe

Abstrack : Malaria is an infectious disease caused by the bite of a female Anopheles mosquito by Plasmodium falciparum. The emergence of malaria is caused by a variety of factors that support vector mosquito Anopheles that is environment factors first, then the behavior, health and heredity. The purpose of this study was to analyze the factors associated with the incidence of malaria in children in the District Work Area PKM Tona Tahuna Sangihe. The research method using analytical survey and research using cross sectional design. The samples in this study using purposive sampling technique to sample 58 respondents. Conclusions The results of research and analysis using Chi Square statistical test to the limit of significance α = 0.05. Results of statistical tests for environment factors p value = 0.207 which means H01 is rejected. Behavioral factors in getting the value p = 0.953 means H02 is rejected. Health care factors in getting the value of p = 0.522 which means H03 is rejected. Recommendation service in PKM Tona more improved quality in the provision of information of malaria in children

Pengaruh Simulasi Tindakan Resusitasi Jantung Paru (Rjp) Terhadap Tingkat Motivasi Siswa Menolong Korban Henti Jantung Di SMA Negeri 9 Binsus Manado

: An emergency situation can occurred whenever and wherever we are. Cardiac arrest is one of the emergency condition which life threatening and needs an immediate intervention. Cardio Pulmonary Resuscitation (CPR) is a intervention that can decide whether the victim of cardiac arrest alive or not. By giving the CPR simulation to the high school students as expected could lift their knowledge and skill, so it can grow the motivation to the students to help people with cardiac arrest if they in the real situation. Purpose to know The Effect Of Cardio Pulmonary Resuscitation (CPR) Simulation To The Motivation Level Of Student To Help The Victim Of Cardiac Arrest in 9 Senior High School Binsus Manado. Samples 33 respondents by using the Total Sampling technique. Design of the research is quasy experiment with one group pre-post test and by using the questionnaire sheet to get the data from respondents. Research result the P-value is 0,00 (< = 0,05). Conclusion shows that there is an effect Of CPR simulation to the motivation level of helping people with cardiac arrest to the students of 9 Senior High School Binsus Manado. Suggestion to the school especially to all the students to use the experience and the knowledge that they already have from the simulation so that they can elevate their motivation to help people with cardiac arrest and for the next research, hopefully they can make a research of the other factors that can elevate the motivation level

Hubungan Response TIME Perawat Dengan Tingkat Kecemasan Pasien Kategori Triase Kuning Di Igd RSU Gmim Kalooran Amurang

Penelitian ini dilatarbelakangi oleh karena adanya pasien gawat darurat pada triase kuning yang menyatakan lama mendapat penanganan dan dibiarkan menunggu dengan kondisi yang tidak nyaman karena nyeri dan keletihan sehingga menyebabkan meningkatnya kecemasan saat berada di ruang gawat darurat. Tujuan penelitian untuk mengetahui hubungan response time perawat dengan tingkat kecemasan pasien ketegori triase kuning di IGD RSU GMIM Kalooran Amurang. Desain penelitian yaitu observasional analitik dengan rancangan cross sectional, populasi yaitu semua pasien IGD yang memenuhi kriteria inklusi. Sampel penelitian ini 77 responden yang didapat dengan menggunakan teknik purposive sampling. Instrumen yang digunakan yaitu kuesioner state anxiety dan lembar observasi response time. Hasil penelitian uji statistik menggunakan uji Chi Square pada tingkat kemaknaan 95% (α ≤ 0,05), maka didapatkan nilai p = 0,001. Ini berarti bahwa nilai p < α (0,05). Dengan demikian bahwa terdapat hubungan yang signifikan antara response time perawat dengan tingkat kecemasan pasien ketegori triase kuning di IGD RSU GMIM Kalooran Amurang. Saran lebih ditingkatkan response time melalui upaya peningkatan SDM, sarana prasarana dan manajemen yang ada agar tercapainya kualitas pelayanan yang bermutu sehingga pelayanan yang diberikan dapat optimal dan pasien bisa merasa lebih tenang dan kecemasan pasien dapat menurun selama berada di IGD

Hubungan Jenis Cairan Dan Lokasi Pemasangan Infus Dengan Kejadian Flebitis Pada Pasienrawat Inap Di RSU Pancaran Kasih Gmim Manado

:More Than 60% of patients who duty The hospital received therapy through IV . IV therapy can be a complication occurred phlebitis . Period Genesis Nosocomial infections Form of phlebitis in Indonesia as much (17.11%). Phlebitis caused by chemical irritation (Infusion fluid types), mechanical (mounting location Infusion), and bacteria. The aim of this research was to determine whether there is a relationship kind of fluid and the incidence of infusion site phlebitis in patients hospitalized in RSU Pancaran Kasih GMIM Manado. Sample is taken by making consecutive sampling technique that is 40 samples. The study design used is analytic survey with cross sectional approach and data were collected using observation sheet.The result of this research with using chi square are (a) relationship between Infusion fluid types with Genesis Phlebitiswhich about p = 0,000, (b) there is a relationship between IV Installation Area with Genesis Phlebitiswhich about p = 0,005.Conclussion(a) there is a relationship between Infusion fluid types with Genesis Phlebitis, (b) there is a relationship between IV Installation Area with Genesis Phlebitis
