1. Introduction

Women represent 52 percent of the world’s population, but do not appear to be included in the careers of science, technology, engineering and mathematics, remaining as a mostly male reducer; starring less than 20% of university enrollments, however the historical trend has been reversing and increasing female participation, especially in some specialties of engineering.

In recent years, there has been an increase in the professional development of women in engineering careers. This is because little by little, myths and beliefs about the position that women have in society have been left behind. [1] Although this insertion in this sector has been difficult for women, they have been placed in different areas where their potential can be exploited.

Women participate as men in the fields of training and especially in the university, but the distribution by career of both sexes is very different. Women opt for careers related to the humanities, education or health sciences to a greater extent. The careers that are within the range of “hard”, such as engineering, remain poorly chosen by women, remaining as a mostly male stronghold. [2]

Thus, far from being able to say that the low percentage of women who decide on engineering careers is something the result of the late incorporation of women into the university, and the world of work in general, and that it will increase as normalized The situation of equality in society, the number of women who opt for engineering continues to decline, regardless of whether women are achieving effective equality in all other aspects of society. [3]

However, it is also recognized that female participation in higher education in Latin America follows in general terms, a pattern that favors some areas of knowledge over others. [4] However, it should be noted that while female participation in areas such as industrial engineering and computer engineering increases, other areas such as mechanical engineering and electrical engineering are still considered as low or nil preference of women.

It is probably because of this, that the work of women is strongly related to the secondary, “supportive” of men, undervalued and undervalued. This means for women a double challenge, on the one hand, joining the work environment and, on the other, obtaining social recognition for their professional performance. [5]

Within these implicit barriers, there are “masculine” standards associated with the scientific career that women must achieve, whether these, for cultural historical reasons, or also associated with the social division of labor. This is how for women scientists the possibility of reaching these standards, is usually, once they have finished with the vital stage of reproduction and / or upbringing, and there arises the problem that is generated by the difference in the years of trajectory. [6]

Peru is no stranger to this problem. According to the National Superintendence of University Education (SUNEDU), it indicates that, in Peru, the total undergraduate graduates in 2016 were 110,408, of which 54.3% were women. However, the largest number of graduates are in the careers of administrative and commercial sciences and in economic and accounting sciences. Of the total graduates, only 26% were from careers linked to the CTI. Of the total CTI graduates, only 32% were women. [7]

Women are increasingly expanding their field of development related to science, technology and innovation. [8] Engineering is no stranger to them, although, the percentage of women linked to the Mechanical and Electrical Engineering Degree is still low.

A study by The National Academies of the United States has found that social stereotypes condition the academic performance of women, leading to a drop of up to 90% in studies when they are not adequately valued. [9] These prejudices cause math and engineering careers to be generally discarded by high school students, which means a loss of talent for society.

2. Methodology

2.1.  Kind of investigation

This research is descriptive. [10] Initially it is intended to identify the percentage of women who graduate in relation to the percentage of men, by academic semester, it should be noted that the National Technological University of South Lima has a total of 15 promotions; In addition, the academic performance of women in the professional career of Mechanical and Electrical Engineering will be analyzed, and it will be determined if there is any type of association between the weighted average by specialty (Mechanical Subjects or Electrical Subjects) with the field of labor action where Currently, women graduated from the degree are working.

2.2.  Population and Sample

The population of this research is represented by the 38 women graduated from the School of Mechanical and Electrical Engineering of the academic semesters 2012-II to 2018-II; It should be noted that the first promotion of graduate students of the university occurred in the academic semester 2011-II, but to date there were no women in the career. It also indicates that women represent 8.1% of the total graduates.

In that sense, the sample will be equal to the population [11]; due to the fact that the sample is less than 50, that is, the general weighted average and the weighted average by specialty (Mechanical Subjects and Electrical Subjects) of the 38 women graduated from the School of Mechanical and Electrical Engineering, until the 2018 II. Below is shown in table 1, the proportion of women and men graduated from the career of Mechanical and Electrical Engineering from 2011-II to 2018-II.

Table 1: Proportion of women and men graduated

2.3.  Measuring Instruments

The instrument used is the technical reports [12], of the notes of the graduates of the professional school of Mechanical and Electrical Engineering; academic records, contained in the university management computer system (SIGU) of the National Technological University of South Lima, were used as a source; in the case of the field of labor development, the files are required as a source, which work in the university’s degree and degree office, which requests the graduates as one of their requirements to submit reports of professional practices, in which Specify the company and the field of development.

3. Results

Figure 1 shows the number of women and men who graduate per academic semester, from the semester 2011-II to 2018-II.

Figure 1: Proportion of women and men graduated by academic semester

As shown in the previous figure, there is a greater number of men graduated in the professional career of Mechanical and Electrical Engineering, as shown in Table 1, this proportion is 8.1% of women graduated and 91.9% of men graduates

Continuing with the investigation, in the following Table 2, the subjects belonging to the areas of specialty are shown; both Electrical and Mechanical subjects.

In order to determine if there is any type of association between the weighted average by specialty (Mechanical Subjects or Electrical Subjects) with the field of labor action where the 38 women graduated from the career currently work, then in Figure 2, the weighted average of the mechanics subjects is shown, while in Figure 3 the weighted average of the electrical subjects is shown.

Figure 2: Weighted average of the subjects of the specialty of mechanics

As it is observed, in the previous figure the average range of the subjects of the specialty of mechanics (AM) is from 11.73 to 15.42; obtaining the highest grade the mechanical engineering laboratory subject; being this course of a practical nature, it provides the student with tests in energy transfer and transformation facilities; Likewise, the interpretation of the results of the experimental tests of the mechanical quantities is disclosed, through fundamental instruments and equipment in engineering.

Figure 3: Weighted average of the electrical specialty subjects

As can be seen, in the previous figure, the average range of subjects in the specialty of electrical (AE) obtained by women graduates is 11.81 to 13.6; obtaining the highest average subjects of Thermoelectric Power Plants and Energy Transformation; being this course of a practical nature; The main objective of the course of thermoelectric plants is to show the state of the art in combustion technology for electricity generation, and the basic knowledge of economics and environment. While in the course of energy transformation it is sought to show the definitions related to the ability to work, transform or set in motion by means of the energy involved, for example in rifle fuels.

With the results obtained, it can be determined that there is a higher qualification in the specialty of Mechanics; Likewise, the general weighted average of both specialties was obtained, of the 38 women graduated, being 12.98; said average is considered high for this professional career; so it can be indicated that the 38 women graduated from the Mechanical and Electrical Engineering career have had a good academic performance.

4. Statistical Analysis

Next, the relationship between the weighted average by specialty (Mechanical Subjects or Electrical Subjects) with the labor field of action of the 38 graduates of the Mechanical and Electrical Engineering career will be determined; by means of the Spearman correlation test, which was carried out with the statistical program SPSS version 25. It should be noted that this test was used because the data does not have a normal distribution. [13] The following table shows the test results.

As the Spearman correlation coefficient is shown in the previous table, it is equal to -0.822. This result can be interpreted in this way: There is a high indirect and significant relationship between the weighted average by specialty with the field of labor action. [14]

Table 3: Spearman correlation

	Sig. (bilateral)	,000	.
	N	38	38
**. The correlation is significant at the 0.01 level (bilateral).

SPSS

These results agree with what has been pointed out in relation to the fact that there is a higher qualification in the specialty of Mechanics and according to the reports of professional practices, of the 38 women graduated from the Mechanical and Electrical Engineering career, 25 are working in the field of Mechanics specialty. The following figure shows the percentage representation of the proportion of working in the labor field of the 38 graduates.

Figure 4: Percentage of the development in the field of labor action

These results agree with what has been pointed out in relation to the fact that there is a higher qualification in the specialty of Mechanics and according to the reports of professional practices, of the 38 women graduated from the Mechanical and Electrical Engineering career, 25 are working in the field of Mechanics specialty. The following figure shows the percentage representation of the proportion of working in the labor field of the 38 graduates.

The reliability criterion of the instrument was determined by Cronbach’s alpha coefficient, developed by J. L. Cronbach and recommended for Likert-type attitude scales; [15] through the reliability test with the statistical program SPSS version 25, the reliability of the instrument will be determined.

Table 4: Reliability test

Cronbach Alfa	N of elements
,930	2

 SPSSAs can be seen, Cronbach’s Alpha is equal to 0.930, so it can be affirmed that there is a “Very High Reliability and Validity of the instrument”, since this value is within the range of 0.90 to 1.00. [15]

5. Discussion

In relation to the results of this research, the following discussions are held below:

Regarding the percentage of women who graduate in relation to the percentage of men, by academic semester of the Mechanical and Electrical Engineering degree of the National Technological University of South Lima, which is equal to 8.1%; This result is similar to the research carried out at the Universidad de los Andes, points out that the world percentage of women graduated from the engineering area represents 7%; This is because currently still the inequality and stereotypes that still prevails in these areas, this discourages women in the decision to pursue engineering careers. [16] Likewise, in Peru, only 25% of students in Engineering careers are women, according to SUNEDU, and of this percentage, less than 5% opt for specialties called “hard”, such as Mechanical Engineering, Electronics, Civil or Mining. The gender gap in science, technology and innovation careers, which is a worldwide trend, is the result of discrimination against women in these areas of study. [17]

In relation to the academic performance of women in the professional career of Mechanical and Electrical Engineering, which is 12.98, this represents a high average for the career; This result is similar to the research carried out in Spain, which indicates that 13.5% of women obtain the highest qualification compared to 10.1% of men [18]; In spite of this, there is still inequality in remuneration, and in companies there is a higher rate of hiring of male engineers. There is another fact that reaffirms the best performance of women. In the UTN of Buenos Aires when the best averages are analyzed, 50% are of the girls, this because they have more dedication, perseverance and responsibility. [19]

Regarding the high relationship that exists between the weighted average by specialty (Mechanics Subjects or Electrical Subjects) with the field of labor action where the women currently graduated from the career work; This result is similar to the research carried out at ECLAC in Santiago, Chile, where it is pointed out that the results of this study confirm that academic performance is a necessary condition for a successful insertion in the labor field. [20]

6. Conclusions

It is concluded that the percentage of women who graduate in relation to the percentage of men, by academic semester 2012-II to 2018-II of the career of Mechanical and Electrical Engineering of the National Technological University of South Lima, is equal to 8.1%.

It is concluded that the weighted average of the academic performance of women graduated in the professional career of Mechanical and Electrical Engineering, is 12.98, this represents a high average for the career; so it can be indicated that the 38 women graduated from the Mechanical and Electrical Engineering career have had a good academic performance.

It is concluded that there is a significant high ratio of 0.822 between the weighted average by specialty with the field of labor action; These results agree with what has been pointed out in relation to the fact that there is a higher qualification in the specialty of Mechanics (AM) with an average range of 11.73 to 15.42, and according to professional practice reports, of the 38 women graduated from The career of Mechanical and Electrical Engineering, 25 are developing in the field of specialty of Mechanics.
