Abstract
According to experts in the training of engineers, the main strengths of engineering professionals is spatial intelligence that helps you understand and manage the physical forms of their environment. The purpose of this research is to determine the best teaching strategies that develop spatial intelligence. Graphic Engineering courses career of Industrial Engineering, University San Pedro, were designed using both instruments and paper, as computer support and solid materials that could be engineered for two-and three-dimensional representation. The research has yielded such results that the strategy applied rises by 24% the rate of spatial intelligence of students tested, which is a significant risk factor increase this capacity, especially considering that the course taught each of them has lasted for only four months. Despite these encouraging results, we believe that subsequently can be performed similar research that considers other factors and assessment methods are perfected, all of which we detail our findings and recommendations.

Abstract
Psychometric properties were determined in the Questionnaire of Dissatisfaction with Body Image (IMAGEN) in students of the National University of Trujillo. The non-random probability sample (n =576) of a population (N = 1272), with a Psychometric design.The results showed that IMAGEN had a valid item-scale construct validity, with very significant correlation indices (p <.01) with its components and with the test, good levels of discrimination that fluctuated (.465-.843). Factor analysis ratified the cognitive behavioral structure, indexes that vary between .915 and .931. Congruent validity reflected a very strong global correlation (r = .899) with BSQ as well as with factor 1 of the aesthetic models questionnaire (r = .823). The reliability by internal consistency is high (α= .953). Stability established a high significance (p <.01) of the test.

Abstract
The Psychometric properties of
the Psychological maturity questionnaire PSYMAS) and its descriptive analysis
were determined. The design was technological-psychometric. The probabilistic
sample at random (n=514) and stratified of a population (N = 2835) Youth
Leaders. For the congruent validity (n 126),
reliability test re test (n = 100) and descriptive analysis (n = 285). For the content
validity, the stratigraphy was the Vindex of Aiken, for the construct validity he
item -test stratigraphy and factorial analysis, congruent validity with Spearman
stratigraphy. Reliability for stability the test-rates coefficient and for internal
consistency the Cronbach’s alpha. The results show clearly that SYMAS has
content validity established by judge’s criteria possessing relevance, clarity
and coherence of the theoretical construct. Validity of the Item-scale
construct rectified. Correlation indexes that are very meaningful (p <.01) with
the global test, very good levels of discrimination that range between 361and
748.The factorial analysis ratifies the structure proposed by the authors, he
adjustment goodness-of-fit responds to the model indexes being very good at
work and identity orientation scales and good at Autonomy dimension.

Abstract
This research was conducted at Hospital El Esfuerzo. The goal was to determine the effect of systematized education on adherence to micronutrient supplementation (SMMN) and the nutritional status of children <3 years old. The sample was made up of 50 mothers and 50 children. The survey technique was used and as instruments a questionnaire and a monitoring card applied in the pre-test and post-test. For the statistical analysis, the Student's T-test and Pearson's correlation coefficient were used. The pre-test results indicate that 74% of those mothers had inadequate adherence regarding the SMMN, and only 26% of them presented adequate adherence. However, in the post-test, 78% of them had adequate adherence, while 22% remained at inadequate adherence. Regarding nutritional status, in the pre-evaluation 60% of children were diagnosed with normal nutrition and 18% with malnutrition. However, in the post-evaluation 80% of children presented normal nutrition and 10% malnutrition. In the pre-evaluation 44% of children presented Hb within the normal range, 30% mild anemia, 20% moderate anemia, and 6% presented severe anemia. Nonetheless, in the post evaluation 72% had normal Hb, 14% moderate anemia, 10% mild anemia, and 4% severe anemia. It is concluded that the systematized education proved to be effective on the adherence of the mothers' SMMN and the nutritional status of the children. This was demonstrated through the Student's T-test, which had a significance of p= 0.000 < 0.05 in the Adherence variable, and the Nutritional Status variable (anthropometry and biochemistry), which had a significance of p= 0.000 < 0.05.

Abstract
In order to identify if the percentage of proteins present in manjar blancowith the addition of seeds of Lupinus mutabilis sweet "Chocho" is higher in comparison to the artisanal and industrialized manjar blanco, a comparative descriptive research was carried out with a non-experimental design, in which the mentioned seeds were used. They were collected from the Province of Huari in the Department of Ancash. In addition, they were selected and classified respecting their optimal organoleptic characteristics. The sample consisted of 5 grams of three delicatessens: manjar blanco,to which Lupinus mutabilis sweet seeds had been added and which traditionally is known as Tarwi or Chocho,the artisanal and the industrialized. The data collection instrument was an observation guide, which showed that manjar blanco with upinus mutabilis sweet seeds contains 6.87 grams of protein in 100 grams of sample, in the artisanal manjar blanco 6.10 gr and in the industrialized manjar blanco 4.58 grams. It was concluded that manjar blanco with Lupinus mutabilis sweet seeds has a higher percentage of roteins present with 98.14% compared to the artisanal manjar blanco with 87.14% and the industrialized manjar blancowith 68.35%.

Abstract
The environmental problems in which people are currently immersed leads us to search for new ways to obtain methods or materials to solve this problem. The materials with magnetic properties give a new solution to this problem. One of the materials with excellent magnetic properties is cobalt ferrite (CoFe2O4). For this reason, this work provides an easy and novel way to obtain this material in the form of thin films. These CoFe2O4 films were deposited by spin coating on Pt (Pt/TiO2/SiO2/Si) substrates at different temperatures (700, 725 and 750 °). For the precursor solution, iron nitrate [Fe (NO3)3∙9H2O] and cobalt nitrate [Co(NO3)2∙6H2O] were used; they were dissolved in 2-methoxyethanol with magnetic agitation for 2 h at 60ᵒ C. In the characterization of thin films, the structure and magnetic properties were studied by X- ray diffraction and vibrating sample magnetometer diffraction pattern confirms the formation of the cubic spinel structure belonging to CoFe2O4 with the preferential peak (311) with no trace of impurities at the studied temperatures. The calculated crystallites are in the range of 10 to 24.34 nm for all samples. The magnetic hysteresis shows that as temperature increases the magnetic properties also increase.
