RESUMEN
This research investigates astronaut performance under simulated space conditions, using THOR, an analog astronaut training protocol, during a week-long confinement in an Analog Astronaut Training Center in Poland. Materials and Five participants, including four military and one civilian, underwent a week of isolation. Tests were conducted to assess heart rate variability HRV, psychological health, and sleep patterns. Data collection and analysis were standardized, with an alpha level of p < 0.05 and power of 80%. The study found reductions in fat percentage and weight, while muscle mass and water content remained stable. HRV showed significant changes. Increased sleep and state anxiety levels were noted, along with decreased cognitive abilities. Personality traits exhibited heightened hostility and social anxiety, culminating in psychological discomfort. HRV values were normal with variations likely due to stress. A significant correlation was found between mental performance and HRV, indicating potential influence of sleep on cognitive function during isolation. The study highlights the need for more research on the psycho-logical and physiological implications of long-duration space missions and similar high-demand environments.
Esta investigación examina el rendimiento de los astronautas análogos bajo condiciones espaciales simuladas durante una semana de confina-miento en un Centro de Entrenamiento de Astronautas Análogos en Polonia. Cinco participantes, incluyendo cuatro militares y un civil, fueron sometidos a una semana de aislamiento. Se realizaron pruebas para evaluar la variabilidad de la frecuencia cardíaca HRV, la salud psicológica y los patrones de sueño. La recolección y análisis de datos fueron estandarizados, con un nivel alfa de p < 0.05 y una potencia del 80%. El estudio encontró reducciones en el porcentaje de grasa y peso, mientras que la masa muscular y el contenido de agua permanecieron estables. La HRV mostró cambios significativos. Se observaron niveles elevados de sueño y ansiedad estado, junto con disminuciones en las habilidades cognitivas. Los rasgos de personalidad mostraron una hostilidad y ansiedad social aumentada, culminando en incomodidad psicológica. Los valores de HRV fueron normales con variaciones probablemente debidas al estrés. Se encontró una correlación significativa entre el rendimiento mental y la HRV, indicando la posible influencia del sueño en la función cognitiva durante el aislamiento. El estudio resalta la necesidad de más investigaciones sobre las implicaciones psicológicas y fisiológicas de las misiones espaciales de larga duración y entornos similares de alta demanda.

The healthcare environment presents a large volume of personal and sensitive patient data that needs to be available and secure. Information and communication technology brings a new reality to healthcare, promoting improvements, agility and integration. Regarding high-level and complex decision-making scenarios, the Brazilian Navy (BN), concerning its healthcare field, is seeking to provide better management of its respective processes in its hospital facilities, allowing accurate control of preventive and curative medicine to members who work or have served there in past years. The study addresses the understanding, structure and clarifying variables related to the feasibility of technological updating and installing of a Hospital Information System (HIS) for BN. In this scenario, through interviews and analysis of military organization business processes, criteria and alternatives were established based on multi-criteria methodology as a decision aid. As methodological support for research and data processing, THOR 2 and PROMETHEE-SAPEVO-M1 methods were approached, both based on the scenarios of outranking alternatives based on the preferences established by the stakeholders in the problem. As a result of the methodological implementation, we compare the two implemented methods in this context, exposing the Commercial Software Purchase and Adoption of Free Software, integrated into Customization by the Marine Studies Foundation, as favorable actions to be adopted concerning HIS feasibility. This finding generates a comprehensive discussion regarding the BN perspective and changes in internal development in the military environment, prospecting alignment to the culture of private organizations in Information Technology for healthcare management. In the end, we present some conclusions concerning the study, exploring the main points of the decision-making analysis and for future research.
RESUMEN
Two bopyrid species parasitizing shrimps of the genus Thor along the Mexican coasts of the Gulf of Mexico and Caribbean Sea are known: Bopyrinella thorii, attaching in the hosts' branchial chambers, and Loki circumsaltanus, attaching to the hosts´ abdomens. Herein, Bopyrinella hadrocoxalis sp. nov. is described, becoming the second described species of the genus in this geographic region. It is found parasitizing Thor manningi in a coastal area in Quintana Roo, Mexico. Loki circumsaltanus is recorded for the first time parasitizing Thor floridanus in Mexican waters; the oostegites, maxilliped and barbula are described and illustrated for the first time.

Aymara people has been a relatively homogeneous group since Spanish Conquest by 1,532 CE, even if previously represented a group of various cultural defined populations who gave rise to them. They were and are established in Andean Altiplano around Titikaka Lake (Bolivia, Peru), Argentina and Chile neighborhood, speak Aymara language and have been maintained after Europeans arrival at a lower social status than Quechua (Inca) speaking people. However, both Aymara and Quechua populations acknowledge Titikaka Lake as center of their origins; both languages are also related. Specific high frequencies of HLA-A*02, -A*24 and -A*68, HLA-B*35, -B*39 and -B*48, HLA-DRB1*08:02, -DRB1*09:01, and -DRB1*14:02, and HLA-DQB1*04:02, -DQB1*03:02 and -DQB1*03:01 alleles are found in Aymaras and HLA class II haplotypes common to Andean Amerindians (DRB1*08:02-DQB1*04:02 and DRB1*04:03-DQB1*03:02), like Quechua, Aymara, Uros, Lamas and Mapuche are also found in Easter and other Pacific Islands. Giant human head stone statues at Tiwanaku (Titikaka Lake, Bolivia) are also found at Easter Island. Thus, it is possible a gene and cultural flow between Andean Amerindians and Easter and other Pacific Islands, as it was demonstrated by Thor Heyerdahl in his Kon-Tiki expedition which reached Pacific Islands sailing from El Callao Harbour (Lima, Peru).

Uros people live in floating reed islands in Titikaka Lake in front of Puno town (Peru). They could have started Tiwanaku culture and shared genes and culture with Pacific Islanders; it is particularly relevant the giant hat covered men statues found in both Tiwanaku at Titikaka Lake shore and Easter Island (3700â¯km far from Chile in Pacific Ocean). These giants monoliths are very similar one another and unique in America and Pacific Islands. The following HLA alleles are shared in a specifically high frequency between Uros and Pacific Islanders : HLA-A*24:02, HLA-B*35:05, HLA-B*48:01, HLA-DRB1*04:03, HLA-DRB1*08:02 and HLA-DRB1*09:01. Uros also have 3 unique HLA haplotypes: A*24:02-B*15:04â¯-â¯DRB1*14:02-DQB1*03:01, A*68:01:02-B*35:05-DRB1*04:03-DQB1*03:02, A*24:02-B*48:01-DRB1*04:03-DQB1*03:02. Also Uros seem to be one of the most ancient population in Titikaka Lake that could have started Tiwanaku culture. Prehistoric contacts between Amerindians and Pacific Islanders are strongly suggested by genetic and cultural traits. It is not discarded that Uros could have come from Pacific Islands: Uros show melanic skin and are dolichocephalic; in contrast, surrounding Aymara people have a clear skin and are brachicephalic. The Kon-Tiki project led by Thor Heyerdahl showed that a simple sailing is possible between Peru and Polynesia Islands; also, the most ancient skull found in America is of black origin: Luzia, suggesting that first America peopling was also carried out by Black/coloured people.
