The manifest forms of verbal or psychological aggression are analyzed, in direct conjunctionwith physical aggression, which are observed constantly, in the familiar areas of the popularsectors and, which are reproduced in school. In fact, the students admit physical aggressionin the home, with figures close to fifty percent in the districts investigated, including withit, the verbal aggression from a majority percentage sense. Of course, what schoolchildrenobserve is a very violent and aggressive home in its different forms, which a large part of thestudents find it impossible to deny. It is manifested, the violence from the parents, but alsowith more rawness the confrontation between the brothers. Not far from all this, communityor neighborhood violence, which also projects alarming figures and that students perceivedaily. It is not a linearity, thinking about explaining the family conflict and its effects on schoolviolence, but warning, the high figures that involve physical aggression in school spaces.

This article presents the design of three graphic interfaces using the graphical user interface(GUIDE) development environment of Matlab, to determine the parameters of a Proportional,Proportional-Integral or Proportional-Integral-Derivative controller from three empirical tuningmethods. Likewise, the purpose of this design was to complement and facilitate the studentslearning the procedure of adjusting the parameters of an industrial controller, simulating it from a scientific computer software such as Matlab. And, as it is a simulation, three differenttransfer functions were selected where the methods of tuning by trial and error, limit gain andreaction curve were applied. Also, such interfaces used objects of type Push Button, Axes, RadioButton, Edit Text, Static Text, among others, thus allowing the entry of the Set Point, showingthe value of the Process Variable and representing graphs according to time. Regarding theresult achieved with the three graphical interfaces designed, it is affirmed that the aim of thetuning was reached by presenting a steady-state error equal to zero, an establishment timevery close to 10 seconds and an impulse envelope absent in one of the cases.

Desenterrando el conflicto. Empresas mineras, actividades y expertos, deFabiana Li, es un texto que invita a discutir el impacto minero en el Perúen estos últimos 20 años.

The Existential Critical Thinking Test of Lima built by Espíritu, Canales, Lunay Torres, explores the purpose of life, considering the essence of life and theintentionality of existence, investigating the objectives that pursues the person.The intentionality has the Pragmatic and Spiritual sub areas. The construct validitywas obtained considering the judgement of six experts and the results wereevaluated using the lawshe index. Fortynine university students participatedin a pilot study in which 5 items were eliminated. The participants were 387 university students and professionals from Lima, to whom the test was appliedin person using an intentional sampling. One item was eliminated. The test finallyresulted in 32 items, with an appropriate reliability index with Cronbach’s alphain the Essence area of .756, in the Pragmatic Intentionality Area of .884 and in theSpiritual Intentionality area of .825. Percentile and T-score norms were drawn upfor the different areas.

Strategies of progressive urban habilitation and co-management to improve the habitat. The experience refers to the placing of technical assistance within the reach organized population, which overcomes the political manipulation partisan of popular interests and demands, for access to basic services and housing, through the exploration of appropriate technologies, within the framework of strategies progressive urban habilitation, comanagement, integral approach, leveraging of resources for habitat improvement, agreed between the population, government locals and government central, to achieve sustainable urban development; as achieved un less than 10 years in North Panamerican Project, which currently driving the northern axis.

This manuscript is part of investigation that was done in the end of second trimesterin the year 2018, in the city of Lima. The objective was make a test in the thirdeducational level in direct relation with syllabus of Management and Conservationof Cultural Patrimony or Naturally Patrimony courses with the purpose to detectweakness for afterwards improve. The analyze considered three professional schoolsof tourism and hostelry in the province of Lima. The instrument that was used toevaluate the syllabus was made for the Education Ph.D. Mr. José Florés Barboza andadapted by the author of this article. The instrument is an ideal model of syllabus for competences, which was a pattern to compare the syllabuses which are subjects of study. The type of investigation is descriptive, also is transversal and quantitativeperspective too, with a sample of three syllabus of tourism and hostelry schools ofLima city.

Su objetivo es difundir lo que es la ficción dada laemergencia de una impresionante actividad para novelar en estos últimos años ennuestro país.

Todo comenzó como un proyecto con fines académicos y científicos alfinal de los años noventa del siglo pasado, entre conversaciones internas,debates, discusiones y entusiasmo. Se gestaba algo que en ese entoncesse elucidaba entre los profesores de humanidades, biología e ingenieríade nuestra casa de estudios. Estaban presentes David Talledo, Teresa Salinas,Ramón León, Julio Mejía, Martha Zolezzi y Luis Figueroa en plena cavilación delos objetivos que se imponían para el proyecto de una publicación ad infinitum,cuyo soporte serían las investigaciones y propuestas académicas que por susresultados tendrían mérito para ser divulgadas. Todos estábamos bajo el impulsode Wilfredo Kapsoli, por entonces Director del Centro de Investigación. Eran losdos primeros años de la gestión del Dr. Iván Rodríguez Chávez como rector yse avizoraba como uno de los primeros fines, enfatizar en la continuidad de laoficina que se encargaba de centralizar los proyectos de investigación de manerainstitucional, con propuestas que lograran establecer el desarrollo de la sociedadperuana. Fue de este modo que en el seno del Centro de Investigación se gestó elprimer número de la Revista SCIENTIA.

The aim of the study was to assess the effect of partial replacement of cracked maize ears with ground maize (GM) or sugar cane molasses (SCM) in supplements for dual purpose cows. Eighteen (18) multiparous cows (414 ± 13 kg of body weight and 106 ± 32 d in milk) were randomly assigned to the treatments. Treatments were as follows: 1) Control supplement (CS) which consisted of 87% of cracked maize ears (CME), 11% soybean meal, and 2% urea; 2) Ground maize replacing 20% of CME in CS (GMS); 3) Sugar cane molasses replacing 18% of CME in the CS (MOS). Each cow received 5 kg/d of supplement DM, whereas their calves received 1.8 kg/d DM of the CS. The experiment lasted eleven weeks, and data were recorded once at the end of every week. Data were analysed using a linear mixed model as a completely randomized design. Net profit from milk and beef due to supplements were estimated using the partial budget approach. There were no differences (P>0.05) between treatments on milk composition, body conditions score, nor daily weight gain of cows and calves. However, compared to GM, CS shown greater (9.0 %, P<0.05) dry matter intake and SCM shown greater milk yield (18.6 %, P<0.05). Partial replacement of cracked maize ears with ground maize or sugar cane molasses, in supplements for dual purpose cows, did not affected animal productive response. However, considered the combined net profit margins (milk and calves), SCM got an average of 9 % higher profits compared of the rest of supplements.
