This paper proposes a slow-moving management method for a system using of intermittent demand per unit time and lead time demand of items in service enterprise inventory models. Our method uses zero-inflated truncated normal statistical distribution, which makes it possible to model intermittent demand per unit time using mixed statistical distribution. We conducted numerical experiments based on an algorithm used to forecast intermittent demand over fixed lead time to show that our proposed distributions improved the performance of the continuous review inventory model with shortages. We evaluated multi-criteria elements (total cost, fill-rate, shortage of quantity per cycle, and the adequacy of the statistical distribution of the lead time demand) for decision analysis using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). We confirmed that our method improved the performance of the inventory model in comparison to other commonly used approaches such as simple exponential smoothing and Croston’s method. We found an interesting association between the intermittency of demand per unit of time, the square root of this same parameter and reorder point decisions, that could be explained using classical multiple linear regression model. We confirmed that the parameter of variability of the zero-inflated truncated normal statistical distribution used to model intermittent demand was positively related to the decision of reorder points. Our study examined a decision analysis using illustrative example. Our suggested approach is original, valuable, and, in the case of slow-moving item management for service companies, allows for the verification of decision-making using multiple criteria.

This article aims to evaluate substance abuse in a sample of personnel who works in the Military Central Hospital through the digital application of two clini-metrical scales, the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) and the Alcohol Use Disorder Identification Test (AUDIT).

Introduction: Quality of life is a multidimensional concept, including physical, material and social well-being and development and activity. It is the subjective perception of general satisfaction that is related to physical, mental and social factors. It allows the realization of the potentialities of the individual in his daily life. Coverage can be categorized into five dimensions: physical well-being, material well-being, social well-being, emotional well-being, and development and activity. Objective: Evaluate the quality of life and morale in military health staff  through the digital application of the Morale Survey and the Q-LES-Q instruments. Material and methods: Observational, transversal and descriptive study. The Questionnaire on Quality of Life: Satisfaction and Pleasure (Q-LES-Q) and Morale Survey were applied to military personnel working in the Military Central Hospital (N= 2519), with a representative sample of the population of n= 1517 for the Q-LES-Q questionnaire and n=1002 for the Morale Survey. Descriptive and inferential statistics were used to evaluate both questionnaires. Results: Of the 1517 individuals only 34% (510) fully answered the Q-LES-Q questionnaire, and of the 1002 individuals in the Moral Survey only 93% (929) fully answered the survey; results showed a tendency of experiencing a good quality of life and a high morale. Conclusions: The Morale Survey is a reliable method (Cronbach’s Alpha coefficient of 0.83) of quality of life and is more likely to be answered completely for evaluation.

This research was carried out in order to determine the incidence of Generalized Anxiety Disorder (GAD) in a health staff sample of the Mexican Army and Air Force, by means of a digital instrument presenting the GADI scale. Data obtained were analyzed in the SPSS v27, obtaining an incidence of 27.51%, this being higher than the prevalence reported in the general world population (3 to 8%) and Mexican (3%); as well as similar to the prevalence of anxiety in military populations of Latin American countries: Ecuador (28.2%), Colombia (more than a third of military personnel under 55 years of age) and Mexico (45.77% in a previous study).

Introduction. Gender violence is a public health problem. The Ministry of National Defense has done strong efforts to educate their personnel about the topic and requires more evaluation of the problem. Objectives. Evaluate the frequency of thoughts that favor the exercise of gender violence, and the experience of people that have suffered it. Material & methods. In the Military Central Hospital, using the SurveyMonkey® platform, staff was evaluated by the digital application of two clinimetrical instruments.  The Scale Inventario de Pensamientos Distorsionados Contra la Mujer (Distorted Thoughts Against Women Inventory) was applied to 1,128, and the scale Uso de Violencia revisado y el Tamizaje de violencia de Género (Gender and Use of Violence Screening Revised Scale) was applied to 1,488. Results. The Distorted Thoughts Against Women Inventory results consisted in 84.8% (956) non-violent, and 15.2% (172) possible violent. From the Gender and Use of Violence Screening Revised Test, 98.2% (1,462) are at low risk, 1.3% (20) at moderate risk, and 0.5% (7) at high risk of having suffered or experiencing gender violence. Conclusions. In the Military Central Hospital there is a low percentage of personnel prone to generate or suffer gender violence, nevertheless, it is required to continue educating all the personnel about the importance of preventing and reporting any gender violence behavior.
