Marine macroalgae and their associated bacterial communities affect larval settlement and survivorship of the coral Pocillopora damicornis

Macroalgae play crucial roles as major habitat-forming organisms in marine ecosystems, having significant impacts on coral recruitment and reef recovery. However, the interactions between marine macroalgae and coral larvae remain poorly understood. Furthermore, little is known whether differences in bacterial assemblages associated with macroalgae may play roles in this process. Here, we comprehensively investigated the impacts of different macroalgae and their associated microbiomes on larval settlement and survival of coral Pocillopora damicornis. The results revealed significant variations in larval settlement and survival rates when exposed to different macroalgal species. The highest settlement rate, reaching 90%, was observed in the presence of the red alga Hypnea pannosa, followed by green algae Caulerpa serrulata, C. racemosa, and brown algae Turbinaria gracilis, Sargassum polycystum. Correspondingly, similarities in bacterial compositions were observed between H. pannosa and C. racemosa, as well as between T. gracilis and S. polycystum, implying associated bacterial may be related with the algal functions. Furthermore, macroalgae that facilitate larval settlement exhibited higher abundances of amplicon sequence variants (ASVs) associated with the metabolism of dimethylsulfoniopropionate or the antagonism of known coral pathogens. However, the brown alga Padina boryana failed to induce larval settlement with survival rate of zero after 120 h. The algal species harbored more abundances of ASVs related to Rhizobiaceae. These findings highlight the significant impact of macroalgae and their associated microbiomes on coral recruitment, as they influence both larval settlement and survival rates.

Composite substrates for coral larval settlement and reef restoration based on natural hydraulic lime and inorganic strontium and magnesium compounds

Coral reefs face unprecedented threats from climate change and human activities, making reef restoration increasingly important for the preservation of marine biodiversity and the sustainability of coastal communities. One promising restoration method relies on coral breeding and larval settlement, but this approach requires further innovation to achieve high rates of settlement and survival. In this study, we built on our previous work engineering lime mortar-based coral settlement substrates by investigating three different compositions of a natural hydraulic lime (NHL) base material as well as composite NHL substrates containing alkaline earth metals. These materials were tested with larvae of three reef-building Caribbean coral species: Orbicella faveolata (Mountainous star coral), Diploria labyrinthiformis (Grooved brain coral), and Colpophyllia natans (Boulder brain coral). We found that the base material composition, including its silicate and calcium carbonate (CaCO3) content, as well as the addition of the inorganic additives strontium carbonate (SrCO3), magnesium carbonate (MgCO3), and magnesium sulfate (MgSO4), all influenced coral larval settlement rates. Overall, NHL formulations with lower concentrations of silicate and higher concentrations of calcium, strontium, and magnesium carbonates significantly increased coral settlement. Further, when dissolved ions of magnesium and strontium were added to seawater, both had a significant effect on larval motility, with magnesium promoting settlement and metamorphosis in C. natans larvae, supporting the observation that these additives are also bioactive when incorporated into substrates. Our results demonstrate the potential benefits of incorporating specific inorganic ion additives such as Mg2+ and Sr2+ into substrates to facilitate early coral life history processes including settlement and metamorphosis. Further, our results highlight the importance of optimizing multiple aspects of coral substrate design, including material composition, to promote settlement and survival in coral propagation and reef restoration.

Geotechnical investigation of soil bearing capacity a case study of Nile university of Nigeria

Geotechnical investigation was conducted within Nile University soil with the aid of the master plan showing areas awaiting future developments. This is as a result of the university planning for infrastructural expansion due to such in student’s population. Each time a building construction is to be taken place, the university management spent another set of money on conducting geotechnical investigation. There are no comprehensive geotechnical information of the soil bearing capacity that can represent the whole of Nile university space/area of 1,153,208,008?2. In-situ and laboratory test were carried out. Three boring point were established using map at a regular interval and drilled to a depth where basement was encountered. In each test sample were collected at 1.5m interval. The standard penetration procedure consist of split spoon and u-tube as set forth in ASTM-1990. The test involves counting the number of blows required to drive a spoon sampler by 300mm, using a weight of 64kg hammer with a free fall of 76mm on the anvil of a rod arrangement. An initial penetration of 150mm is allowable on the sampler known as sitting blows before counting the subsequent blow for the required 300mm. another six trial pit were evenly spread at regular interval at different location within the university. It was manually excavated by hand, undisturbed and disturbed sample were extracted by hand auger and shovel. Sample were extracted at 1.5m depth, properly labelled and taken to laboratory. The laboratory test of the extracted soil sample include moisture content, grain size distribution, liquid limit, plastic limit, consolidated drained test and unified soil classification system was adopted. It was observed that the results obtained from Standard Penetration test indicates variance in allowable bearing capacity with depth, between 0.0-0.5m is 56??⁄?2, 0.6- 1.0m is 112??⁄?2, 1.5- 2.0m is 215??⁄?2, 3.0 – 3.5 is 279??⁄?2, 4.5 – 5.0m is 273??⁄?2. The soil type were predominantly medium dense to very dense inorganic silty sand with clay content less than 5%. Point of refusal was encounter at 6m depth, boring was then terminated. The Direct shear box test analyses obtained from site BC and CH gave the allowable bearing capacity values of 250??⁄?2 at pit one, 211.2??⁄?2 at pit two, 798.1??⁄?2 at pit three, at pit four, 798.1??⁄?2, at pit five, 918??⁄?2 , at pit six 960.5??⁄?2, but with the results obtained from oedometer test show that we cannot adopt this allowable bearing capacity value due to it high settlement rate beyond the acceptable settlement rate set by Development Control in Nigeria, which is 100mm. therefore based on the result from oedometer test the allowable bearing capacity of 120??⁄?2 was adopted with a safe consolidated settlement of 52mm at site BC. While an allowable bearing capacity of 100??⁄?2 with safe consolidated settlement of 55mm was adopted for site CH. Site BC is predominantly underlain by Sandy Silt. While site CH the predominant soil type was Clayey Sand. Pad footing at 1.5m depth and 210??⁄?2 allowable bearing capacity should be adopted. It is recommended that for both site BC and CH pad foundation at 1.5m having maximum individual column load less than 600??⁄?2 with a ground beam adopted.

디지털 시대의 보험설계사

The insurance industry is facing a changing market environment due to the entry of big tech companies, changing consumer needs, and a preference for general agencies(GA) among solicitors. In particular, as the entry of big tech companies deepen their presence, insurance companies have introduced “digital insurance solicitors” as one response to strengthen their business capabilities. Unlike traditional insurance solicitors, digital insurance solicitors have low entry barriers and high work freedom. This provides an opportunity to become an insurance solicitor through online training, even offers online work environment for sales activities. Therefore, people who have had little or no experience in the insurance industry, such as working professionals seeking part-time jobs, graduate students, and homemakers, can work as insurance solicitors using their free time. Digital insurance solicitors can create positive effects such as increased opportunities for acquiring new customers and expanding customer touchpoints for insurance companies. However, efforts are needed to minimize expected side effects including incomplete sales due to a lack of insurance-related knowledge. Incentives are also recommended to encourage sales activities and maintain high settlement rates. Insurance companies need to continue to establish and monitor suitable support systems for the digital environment including expanding online and offline education to enhance the overall capabilities of digital insurance solicitors. The insurance industry's new and proactive attempt to respond to environmental changes, the “digital insurance solicitor”, should be watched with attention.

Proteomic response of early juvenile Pacific oysters (Crassostrea gigas) to temperature.

Pacific oysters (Crassostrea gigas) are a valuable aquaculture product that provides important ecosystem benefits. Among other threats, climate-driven changes in ocean temperature can impact oyster metabolism, survivorship, and immune function. We investigated how elevated temperature impacts larval oysters during settlement (19–33 days post-fertilization), using shotgun proteomics with data-independent acquisition to identify proteins present in the oysters after 2 weeks of exposure to 23 °C or 29 °C. Oysters maintained at elevated temperatures were larger and had a higher settlement rate, with 86% surviving to the end of the experiment; these oysters also had higher abundance trends of proteins related to metabolism and growth. Oysters held at 23 °C were smaller, had a decreased settlement rate, displayed 100% mortality, and had elevated abundance trends of proteins related to immune response. This novel use of proteomics was able to capture characteristic shifts in protein abundance that hint at important differences in the phenotypic response of Pacific oysters to temperature regimes. Additionally, this work has produced a robust proteomic product that will be the basis for future research on bivalve developmental processes.

Prediction of track settlement at high-speed railway transitions between embankment and bridge in the proximity of a turnout

It is well known that transition zones are subject to high differential settlement rates mainly due to the rapid change in track system stiffness as well as materials used. This problem is even more notable in high-speed lines where the dynamic effects are critical. In this paper, a methodology that combines large FE track models and vehicle-track MBS software with relatively low computational costs is proposed to calculate the long-term track behaviour in transition areas. The substructure dynamic characteristics are captured using an equivalent Lump Parameter (LP) model whose parameters are tuned against the FE track model to correctly reproduce the frequency response of the full track. The dynamic behaviour of the whole system is predicted using the in-house vertical vehicle-track software RailDyn. A settlement algorithm accounting for the development of hanging sleepers is then used in iterative simulations. A typical European high-speed transition zone between embankment and bridge is considered as a case study and various scenarios are analysed, including when a switch is located in proximity. Results show that the cement-bound reinforced and layered design considered creates a smooth increase of stiffness through the transition. On the other hand, localised differential settlement is predicted at the position of change in track stiffness, leading to an increase of stress in the ballast layer and a decrease in the layers beneath. The long-term soil behaviour at the switch panel is found to be completely dissociated from the behaviour at the transition when located at or more than 25 m from the bridge, as is the current practice.

Novel shaker bottle cultivation method for the long spined sea urchin (Diadema antillarum; Philippi, 1845) results in high larval survival and settlement rates

The long spined sea urchin Diadema antillarum was an abundant grazer on Caribbean coral reefs, until 1983–1984, when densities were reduced by ∼98% during a region wide die-off. Since then, there has been very little natural recovery of the species and interest is growing in applying aquaculture as a tool for population enhancement. In this study we optimized a new shaker bottle cultivation method for D. antillarum. The method was tested in a series of experiments by culturing D. antillarum from egg to juvenile in the Netherlands as well as the USA. Larvae were cultured in standard 1-L glass reagent bottles, suspended by gentle constant movement on an orbital shaking table and fed with either the microalgae Rhodomonas lens or Rhodomonas salina. Effects on larval growth and survival were evaluated for different microalgal feeding concentrations, larval densities, and culture temperatures. Larval density and growth were measured twice a week over a period of up to 56 days.Larvae grew significantly faster on a higher feeding concentration up to 90,000 Rhodomonas sp. cells mL−1, twice weekly, compared to 30,000 and 60,000 cells mL−1. A density of 1 larvae mL−1 resulted in the highest body size and survival compared to densities of 2 or 4 larvae mL−1. Overall survival from larva to settled juvenile urchin increased from 8 to 10% settlement to 32–33% when the initial density was lowered further from 1.2 to 0.4 larvae mL−1. Growth, survival, competency and settlement did not differ between larval cultures kept at 25 °C or 28 °C.We believe that this novel method for culturing D. antillarum larvae, once scaled-up and validated to pilot scale, could provide juveniles for restocking of urchin-depleted reefs that suffer from algae overgrowth.

Farewell Anatolia: Refugees & the rise of the Greek Left

The population exchange of 1923 between Greece and Turkey consolidated the influx of more than 1.5 million refugees from Anatolia and East Thrace into Greece. In this article, we exploit the regional distribution of refugees at the sub-prefectural (province) level as a natural experiment in order to delineate the political effects of what the Greeks call the Asia Minor Catastrophe. We find that the settlement of refugees produced positive persistent effects on the electoral share of left-wing parties in the interwar and postwar periods. This is particularly the case for provinces with a high settlement rate of refugees originating from Asia Minor rather than from East Thrace or the Black Sea region. However, the refugee impact on the left-wing vote disappears completely in the post-dictatorship period.

Settlement Around the World: Settlement Rates in the Largest Economies

Abstract This article presents the first rigorous, multi-country analysis of settlement rates. Data on settlement were collected for twenty-three of the twenty-five largest economies. Settlement rates vary greatly, from below 15% in France, Belgium, and Russia, to over two-thirds in Australia. Settlement rates also vary by subject matter, with settlement rates generally highest in tort, especially in the U.S. There are also dramatic differences in settlement rates by legal origin, with common law countries generally having the highest settlement rates. Because settlement rates in civil law countries are so low, selection effects may not be a significant problem for empirical work involving them. Higher settlement rates are correlated with early disclosure and shorter court delays, but more research is needed to explain the large differences in settlement rates.

Migration behaviors of microplastics in sediment-bearing turbulence: Aggregation, settlement, and resuspension

The interaction between microplastics (MPs) and suspended sediment (SS) is important for the environmental fate of MPs. This study explored the interaction of MPs with SS and the vertical migration behavior of MPs in sediment-bearing turbulence. The turbulent shear flow caused MPs to aggregate. This aggregation resulted in a rapid increase in particle size, which peaked when the shear rate was 19.94 s−1, and then declined with a further increase in the shear rate. Compared to large MPs, small MPs were more prone to aggregation, which formed heterogeneous aggregate MPs-SS in sediment-bearing turbulence. Owing to the formation of heterogeneous aggregates, small MPs had a much higher settlement rate in sediment-bearing turbulence than in sediment-free turbulence. MPs in bottom sediments may resuspend owing to turbulent shear flow acting on sediments, causing secondary pollution. These results provide new insights into the aggregation, settlement, and resuspension behaviors of MPs in natural waters.

Settlement of Bivalve Spat on Artificial Collectors (Net Bags) in Two Commercial Mussel Parks in the North-Western Adriatic Sea

Among aquaculture activities, shellfish culture is considered more sustainable and beneficial in terms of food security. Currently, only a few bivalve species are reared and there is a need to explore the possibility to introduce new candidates for shellfish farming. Due to the lack of information on bivalve recruitment in the North-Western Adriatic Sea, in this study, the possibility to collect natural spat of commercial species was investigated. Artificial collectors (net bags) were deployed in two sites, Pellestrina and Caleri (North-Western Adriatic Sea), within two commercial mussel parks, during the spring–summer and summer–autumn periods. At both sites, collectors were placed at a distance of 1 m from each other, from 5 to 14 m depth. The influence of season, site and depth on bivalve recruitment was inspected and the presence of invasive species was also evaluated. In all, 28 bivalve taxa were found, and a higher settlement rate was observed in summer–autumn compared to the spring–summer period. Mytilus galloprovincialis, Flexopecten glaber, Mimachlays varia and Aequipecten opercularis were the most abundant species in spring–summer. In the summer–autumn period, in both sites analysed, a very high quantity of Anadara transversa and F. glaber were found. Indeed, these species were dominant at Pellestrina and Caleri, respectively. Another non-indigenous species, Arcuatula senhousia, was also detected. Relevant amounts of Pectinidae spat, F. glaber in particular, were collected and the optimal depth range for the scallop spat collection was found to be between 8 and 14 m. Our results highlight the relevant potential of Pectinidae spat collection along the North-Western Adriatic coasts, even though the presence of invasive species needs to be monitored.

High peak settlement of Diadema antillarum on different artificial collectors in the Eastern Caribbean

The massive die-off of the herbivorous sea urchin Diadema antillarum in 1983 and 1984 resulted in phase shifts on Caribbean coral reefs, where macroalgae replaced coral as the most dominant benthic group. Since then, D. antillarum recovery has been slow to non-existent on most reefs. Studying settlement rates can provide insight into the mechanisms constraining the recovery of D. antillarum, while efficient settlement collectors can be used to identify locations with high settlement rates and to collect settlers for restoration practices. The aim of this study was to compare pre and post die-off settlement rates and to determine possible settlement peaks in the Eastern Caribbean island of St. Eustatius. Additionally, we aimed to determine the effectiveness and reproducibility of five different settlement collectors for D. antillarum. D. antillarum settlement around St. Eustatius was highest in May, June and August and low during the rest of the study. Before the die-off, settlement recorded for Curaçao was high throughout the year and was characterized by multiple settlement peaks. Even though peak settlement rates in this study were in the same order of magnitude as in Curaçao before the die-off, overall yearly settlement rates around St. Eustatius were still lower. As no juvenile or adult D. antillarum were observed on the reefs around the settlement collectors, it is likely that other factors are hindering the recovery of the island's D. antillarum populations. Of all five materials tested, bio ball collectors were the most effective and reproducible method to monitor D. antillarum settlement. Panels yielded the least numbers of settlers, which can partly be explained by their position close to the seabed. Settler collection was higher in mid-water layers compared to close to the bottom and maximized when strings of bio balls were used instead of clumps. We recommend research into the feasibility of aiding D. antillarum recovery by providing suitable settlement substrate during the peak of the settlement season and adequate shelter to increase post-settlement survival of settlers. The bio ball collectors could serve as a suitable settlement substrate for this new approach of assisted natural recovery.

Scientific investigation of metakaolin-based cement concrete with rock sand infill

Concrete containing pores may perform poorly, when exposed to high shrinkage and settlement rates. The purpose of this study was to use Metakaolin and rock sand to improve concrete performance by reducing voids. Metakaolin has proven to be an effective supplemental cementitious ingredient in cement concrete. The most commonly utilised additives in concrete are metakaolin and its characteristics. Because metakaolin is widely available in our country, it may bring economic benefits when used in cement concrete. A substitution proportion of metakaolin of 5 percent, 10 percent, 15 percent, 20 percent, and 25 percent by weight of cement was to be used. Concrete is tested by casting cubes and cylinders to see how long it lasts and how strong it is. In 15 percent MK-based concrete, increases in compressive strength of 47.55 percent, 27.88 percent, and 47.52 percent were found after 7, 28, and 90 days, respectively.

Stabilization of Johor Peat Soil using Sugarcane Bagasse Ash (SCBA)

Peat soil have been categorized as a problematic organic soil, because they have a high settlement rate when placed any structure on it. Therefore, the peat soil must first be stabilized using cement before it can be used. However, massive use of cement can lead to environmental pollution. Therefore, this study intends to use sugar cane bagasse ash as a substitute for cement in peat soil stabilization. The mix ratio of 5% to 20% was used to find the optimal mix ratio. Various tests were carried out on samples such as basic properties tests, Unconfined Compressive Strength (UCS) and Scanning Electron Microscope (SEM). After all the tests, the 5% replacement SCBA mix ratio gave the highest unconfined compressive strength if compared to the other mixtures ratio. Therefore, it is selected as the optimum mix ratio. The soil strength achieved by the SCBA 5% replacement ratio was found to be higher than cement stabilization alone due to the presence of secondary pozzolan reactions. The microstructure result from the SEM test had shown that the 5% replacement SCBA mix ratio filled in the hollow left by the peat soil. Hence, able to improve its soil structure and thus increasing its strength.

Penerapan Metode K-Means Dalam Mengelompokkan Banyaknya Desa/ Kelurahan Menurut Keberadaan Permukiman Di Bantaran Sungai Berdasarkan Provinsi

The research aims to classify the settlements along the river banks by province. To solve this problem, the researchers applied the K-Means Algorithm method. Where the source of research data was collected based on documents explaining the number of villages / sub-districts according to the existence of settlements on the river banks produced by the Central Statistics Agency (BPS). The data used in the study are data from 2014 - 2018 which consists of 34 provinces. The data will be processed by clustering in 2 clusters, namely the settlement level cluster on the high riverbank and the settlement level cluster on the low riverbank. The high cluster consists of 11 data, namely the provinces of Aceh, North Sumatra, Jambi, South Sumatra, West Java, Central Java, East Java, West Kalimantan, Central Kalimantan, South Kalimantan, and South Sulawesi. By conducting the research, it can provide input and as a solution to related parties in charge of dealing with settlement problems along the river banks, especially for the government, in order to get more attention in provinces with high riverbank settlement rates.

Farewell Anatolia: Refugees & the Political Economy of New Greece

The population exchange of 1923 between Greece and Turkey consolidated the influx of more than 1.5 million refugees from Anatolia and East Thrace into Greece. In this paper, we exploit the regional distribution of refugees at the sub-prefectural level as a natural experiment in order to delineate the political and economic effects of what the Greeks call Asia Minor Catastrophe. We find that the settlement of refugees produced positive persistent effects on the electoral share of left-wing parties such as the Communist Party in 1932 and the United Democratic Left in 1963. This is particularly the case for province districts with a high settlement rate of refugees originating from Asia Minor rather than from East Thrace and the Pontus (Black Sea) region. Mortality rates also persistently rose in Greek provinces with a high share of Ottoman Greek refugees both in the interwar and the postwar period. Moreover, Asia Minor refugees appear to have contributed to a rise in Greek human capital in the postwar period.

Kazakistan Korelilerinin Sosyo-Kültürel Yapısı

This study under the title Sociocultural Structure of the Koreans of discusses the history of forced migration and the current sociocultural status of Koreans in Kazakhstan society. Kazakhstan Koreans are one of the ethnic groups that make up Kazakhstan and their population is around 100,000. The data for the study was collected by using quantitative and qualitative research methods to examine the language, religion, ethnic identity, education, economic and social life status of Korean in Kazakhstan. The culture of Koreans in Kazakhstan is in close contact with their past and present lands, state policies, other communities in the region, and their cultures. Due to the low Korean population in this region, a lack of national autonomy, high urban settlement rate, and rapid socioeconomic development, Koreans have adapted to Russian culture and particularly to Kazakh culture while retaining part of their ethnic identity. They have almost forgotten Korean language which is their mother tongue. One of the characteristics of the state of religion is the distribution of people to various religions without having a main religion like most other ethnic groups. Their educational and economic situation is higher and more stable than other nations in Kazakhstan society.

Protection heterogeneity in a harmonized European patent system

This study proposes a divergent expectation model for patent infringement disputes, where both litigation and settlement are driven by patent quality. Under the model, patent quality depends on both broadness and definiteness of the patent. The model predicts that technologies where the definiteness attribute can be estimated with high accuracy will have higher settlement rates. At trial, it is rather the assessment of the patent quality by the judge which decides the outcome. In its empirical section, the paper evaluates over a thousand hand-collected and hand-coded patent infringement and counterclaim decisions rendered by courts in the three largest patent granting European countries—Germany, France and the United Kingdom. The paper utilizes empirical methods to investigate whether the characteristics of the patents or the country of litigation predict the outcome of litigation. Examination of the patent characteristics is guided by the factors of our model, in that the patent quality, and underlying technology and industry are tested. The findings provide evidence of the continuing heterogeneity of the patent systems in Europe, despite the harmonization efforts. Demonstrated was the lack of importance of the characteristics of the litigated patent; rather, it was the forum to which the case was brought that was decisive. At the dawn of the Unified Patent Court, our study provides for a window into the extent of heterogeneity still prevailing and a starting point for monitoring the further development of European patent harmonization.

Geological investigation of the settlement behaviour of two highways in Lianyungang region

In the past 20 years, more than ten highways are built in the Lianyungang region, Jiangsu province, China. Among them, two highways (Coastal Highway A, close to the coastline, and Lianyan Highway B, approximately 25 km from the coastline) are crucial to the local highway network. However, the settlements of these two highways are significantly different, despite the same building method and location in a region with similar sediment provenance and sedimentary environment. A higher settlement rate was observed for the highway constructed far from the coastline. To clarify the mechanism, a series of field and laboratory tests based on regional geological survey were conducted in this study. Test results showed that the sensitivity difference of the soil induced by the pore water salinity leaching is the main reason for those observations. With pore water salinity leaching, the water content and plastic limit of Lianyungang marine soft clays remained almost unchanged, whereas the liquid limit and plasticity index of the soft clay near highway B gradually decreased with an increase in the liquidity index. The increase in the liquidity index subsequently decreased the remoulded strength of the soils far from the coastline. Simultaneously, the natural strength remained approximately the same due to leaching, and this led to an increase in the sensitivity, suggesting a strong structure. During the filling construction, the construction load and deviatoric stress under the embankment may have destroyed the clay structure. Therefore, a large settlement and high settlement rate resulted for the highway constructed far from the coastline.

Prevalence of the Settlement of Medical Residences in the State of Tocantins in the Period 2013-2017

Abstract: Introduction: The accomplishment of medical residency (MR) is a type of qualification considered to be the “gold standard” for medical specialization. Understanding whether there is actually greater professional settlement or not stimulated by MR and which factors hinder or contribute to the physician’s permanence in that place, are important information for the structuring of medical residency and health system programs. The aim of this study was to evaluate the prevalence of settlement of medical residents who finished the residency training in the state of Tocantins, after the implementation of medical residency programs in the period from 2013 to 2017. Method: This is an observational quantitative research, with a cross-sectional, descriptive and analytical design, using the telematic technique and its own questionnaire, carried out with 44 medical residents that finished the medical residency program in the state of Tocantins. The project was reviewed and approved by the Ethics Committee of the Federal University of Tocantins (UFT) under Opinion number 2.292.540. Results: The prevalence of settlement was 65.9% of physicians in the state of Tocantins. Most residents were females (59.1%), with a mean age of 30.8 ± 3.1 years, income between 10 and 20 minimum wages (55.8%) and worked during their residency training (84.1%). The specialties that showed the highest settlement rates were general surgery and clinical medicine, and among these, the majority works for the private and state health networks. The main reason for not settling in Tocantins was to attend another residency or subspecialty program in another state (64.7%). Conclusion: The prevalence of medical residents that finished the residency and settled in Tocantins during the analyzed period can be considered high (65.9%). The fact that most of these individuals are young and female and the reason for not settling in the state are important indicators to be analyzed together with the settlement process and the offering of positions in the specialties available in Tocantins. The results of the study indicated a favorable and strategic perspective of the Medical Residency Programs (MRP) in the medical settlement in Tocantins, which cannot be generalized to the reality of such an unequal health system in the country. A larger public investment in the structuring of health network services is necessary, especially in the municipal network, in the organization of support and socioeconomic development of cities.
