Aim. This study aimed to investigate the mechanisms of autonomic regulation and autonomic support in focal frontal and temporal lobe epilepsy. Materials and Methods. Thirty-six individuals were examined (19 men and 17 women; mean age 33.71.4 years) in the control group (without history of epileptic seizures) and 68 patients (32 men and 36 women, 34.11.5 years) with focal epilepsy (36 patients with frontal lobe epilepsy, of which 32 had temporal lobe epilepsy). Physiological parameters of heart rate variability and of skin sympathetic evoked potentials were evaluated. Results. Predomination of sympathetic influences in both groups of patients was found. According to the analysis of skin sympathetic evoked potentials, a high activity of the suprasegmental autonomic centers was determined in patients with epilepsy. Based on the results of the correlation analysis, the initial state in patients with temporal lobe epilepsy was characterized by greater intrasystemic tension that reflects the high level of physiological costs. The logit regression analysis model makes it possible to distribute patients with focal epilepsy into groups with different disease courses on the basis of the parameters of the autonomic support of the activity. Conclusion. In patients with focal epilepsy, predomination of sympathetic influences was observed, as well as greater activity of the suprasegmental centers of the autonomic regulation. Intrasystemic ratios of autonomic regulation parameters demonstrate an increase in the intrasystemic tension and a limitation of functional reserves in patients with temporal lobe epilepsy. A complex of parameters of autonomic support allows, based on the logit regression analysis, to distribute patients into groups with different courses of focal epilepsy.

Since 1984, the Japan internship program has been implemented to increase the capacity and income of young farmers in Indonesia. The existence of internship activities has changed the mindset and abilities of farmers in their farming organizations, even some of the trainee had changed their agribusiness sector when this program had ended. The purpose of this study was to identify factors that influenced farmers’ decisions in changing their agricultural businesses after the Japaninternship program. This research was conducted in East Java Province, Indonesia from September 2020 to February 2021. The farmers were selected purposively as many as 34 people. Data were analyzed using logit regression analysis. The results of the analysis showed that the factors that significantly influenced farmers’ decisions to change the type of agribusiness sector were the motivation level in the business, business experience, the existence of business license, presence of business brands, and participation in agricultural institutions. The existence of Japaninternshipactivities has changed the mindset of farmers to better manage their businesses. In addition, some farmers have even changed their agribusiness sector to a more profitable business.

The intellectual capital is a catalysator of the country’s economic growth. The developed countries try to develop attractive conditions for highly qualified migrants to diffuse the knowledge and innovations. The authors provided the bibliometric analysis of the papers, which focused on the analysis of the migrant issues was done. For the bibliometric analysis, the metadata of 2 500 papers was selected from Scopus. The results showed that the numbers of Scopus documents on the allocated theme have increased for 2015 year. The most powerful investigations were provided by scientists from the USA, Canada, France, United Kingdom. The bibliometric analysis findings confirmed that the scientists allocated a vast range of the determinants that could stimulate or restrict the migrants in the country. Thus, the governance efficiency had the mediation role between the migration and innovation development of the country. In this case, the paper aims to check the hypothesis that the increasing (decreasing) level of country innovation development and government efficiency from year t − 1 to year t positively (negatively) affects net migration in year t + 1. The panel data for 2011-2018 was generated from IndexMundi, EU Data Portal, WorldBank. The object of the investigation was Bulgaria, Croatia, Lithuania, Latvia, Poland, Romania. The dependent variables – net migration rate, the independent variables – World Government Indicators: Control of Corruption, Government Effectiveness, Political Stability, Rule of Law, Regulatory Quality, Voice and Accountability (for assessment of government efficiency), Innovation Index (for assessment of country's innovation development). In the paper, to check the hypothesis, the authors used the Fully Modified Ordinary Least Square for homogeneous and heterogeneous models. The findings confirmed that innovation development and governance efficiency (Political Stability and Absence of Violence/Terrorism, Regulatory Quality, Voice and Accountability) had a statistically significant impact on the migration rate. The findings could be used to identify the strategic goals of innovation development to overcome the demographic issues and support the migration of the high qualified workforces.

В статье рассматриваются миграции бурятского народа в районах преимущественного расселения в 1959–1989 гг. Анализируются источники и методы исследования этнических миграций. Изучена территориальная специфика пространственных перемещений бурятского населения на фоне миграционных тенденций в России в целом и в восточных районах, в частности. Вычислен его механический прирост/убыль в Иркутской и Читинской областях, Бурятской АССР, определены исторические условия, факторы и географические направления миграций, роль сельско-городских перемещений. Выявлено, что буряты Иркутской области обладали самой высокой мобильностью, благодаря тесным контактам с русским населением, интенсивному аграрному и промышленному развитию региона, из-за чего механический отток из области достиг больших размеров. Если вначале была велика доля так называемых «внутренних миграций», в районах основного расселения, то постепенно роль экономических перемещений усилилась, а роль Бурятской АССР как центра притяжения ослабла. У бурят БАССР на протяжении всего рассматриваемого периода было положительное сальдо миграции за счет притока из Предбайкалья и Читинской области. Миграционная подвижность этноса здесь была значительно ниже, чем в Иркутской области, а масштабы сельско-городских миграций были невелики из-за сравнительно невысоких темпов экономического развития и менее тесных контактов с русским населением. Вместе с тем, приток бурятского населения в республику в изучаемый период последовательно снижался. В Читинской области демографический переход у бурятского населения шел медленнее, чем в других регионах преимущественного расселения. В этой связи миграционная мобильность этноса была очень низкой. Регион исторически отличался самыми невысокими темпами роста промышленного производства, меньшей была интенсивность аграрных переселений. В результате буряты области дольше сохраняли традиционные виды хозяйствования, доля городских жителей была небольшой, распространенность русского языка была невысокой. Мобильность бурят усилилась в 1970-е гг., в основном миграции были направлены в БАССР. Роль республики как региона вселения упала лишь в 1980-е гг. The paper studies migration patterns of the Buryat people in the areas with dense Buryat population in 1959–1989. The sources and methods of studying ethnic migrations are analyzed. The territorial specifics of movements of the Buryat population in the context of migration trends in Russia in general and in the Eastern regions in particular are examined. Net migration rate in the Irkutsk and Chita regions and the Buryat ASSR was calculated. Historical conditions, factors and geographical directions of migration, and the role of rural-urban movements were identified. It was revealed that the Buryats of the Irkutsk region had the highest mobility, due to close contacts with the Russian population, intensive agricultural and industrial development of the region, which is why the migration outflow from the region dramatically increased. At first, most migrations were within the studied areas, but then the role of economic movements gradually increased, and the role of the Buryat ASSR as a center of attraction weakened. During the entire period under review, the Buryats of the BASSR had a positive net migration rate due to inflows from the Baikal region and the Chita region. The migration mobility of this ethnic group was significantly lower than in the Irkutsk region, and the rural-urban migration rate was low due to relatively slow economic development and less contacts with the Russian population. At the same time, the influx of Buryat population to the Republic in the studied period consistently decreased. In the Chita region, the demographic transition of the Buryat population was slower than in other regions under consideration. The region has historically had the lowest industrial production growth rates, and the agricultural migrations were less intensive. As a result, the Buryats of the Chita region had long maintained traditional economies, the share of urban residents was low, and Russian language use was not widespread. The mobility of the Buryats increased in the 1970s, and migrations were mainly directed to the BASSR. The role of the Republic as a destination for migrant flows only declined in the 1980s.

Metode analisis yang digunakan adalah metode tabulasi data untuk menggambarkan persepsi petani terhadap teknologi informasi. Analisis untuk mengetahui pengaruh teknologi informasi dan faktor lain terhadap risiko produksi adalah analisis regresi logit. Hasil menunjukkan bahwa teknologi informasi bermanfaat dalam kegiatan usahatani kentang khususnya untuk informasi harga dan pasar. Faktor-faktor yang berpengaruh terhadap sikap petani pada risiko harga adalah usia, harga sebelumnya, harga saat ini dan penggunaan teknologi informasi. Teknologi informasi sangat bermanfaat bagi petani dataran tinggi khususnya petani kentang yang terbatas akan akses informasi sehingga perlu adanya penyediaan sarana prasarana yang memadai untuk kemudahan penggunaan teknologi informasi. Perlu ada sarana yang menyediakan informasi harga dan pasar secara terbuka untuk petani. ABSTRACTPurpose of this study is (1) to determine the perception of potato farmers on the use of information technology, and (2) to analyze the effect of the use of information technology and other factors on farmer's behavior on the potato price risk. The study was conducted in Pasuruan Regency with 183 respondents. The analytical method used is the data tabulation method to describe farmers' perceptions of information technology. Analysis to determine the effect of information technology and other factors on production risk is logit regression analysis. The results show that information technology is beneficial in potato farming activities especially for price and market information. The factors that influence the attitude of farmers to price risk are age, previous prices, current prices and the use of information technology. Information technology is very beneficial for highland farmers, especially potato farmers, who are limited in access to information, so there is a need to provide adequate infrastructure to facilitate the use of information technology. There needs to be a means that provides information on prices and markets openly for farmers.

Background Previous studies exploring the factors associated with the incidence of syphilis have mostly focused on individual-level factors. However, recent evidence has indicated that social-level factors, such as sociodemographic and socioeconomic factors, also affect the incidence of syphilis. Studies on the sociodemographic and socioeconomic factors associated with syphilis incidence are scarce, and they have rarely controlled for spatial effects, even though syphilis shows spatial autocorrelation. Methodology/Principal findings Syphilis data from 21 cities in Guangdong province between 2005 and 2017 were provided by the National Notifiable Infectious Disease Reporting Information System. The incidence time series, incidence map, and space-time scanning data were used to visualize the spatiotemporal distribution. The spatial panel data model was then applied to explore the relationship between sociodemographic factors (population density, net migration rate, male:female ratio, and the number of health institutions per 1,000 residents), socioeconomic factors (gross domestic product per capita, the proportion of secondary/tertiary industry), and the incidence of primary and secondary syphilis after controlling for spatial effects. The incidence of syphilis increased slowly from 2005 (11.91 per 100,000) to 2011 (13.42 per 100,000) and then began to decrease, reaching 6.55 per 100,000 in 2017. High-risk clusters of syphilis tended to shift from developed areas to underdeveloped areas. An inverted U-shaped relationship was found between syphilis incidence and gross domestic product per capita. Moreover, syphilis incidence was significantly associated with population density (β = 2.844, P = 0.006), the number of health institutions per 1,000 residents (β = -0.095, P = 0.007), and the net migration rate (β = -0.219, P = 0.002). Conclusions/Significance Our findings suggest that the incidence of primary and secondary syphilis first increase before decreasing as economic development increases further. These results emphasize the necessity to prevent syphilis in regions at the early stages of economic growth.

OBJECTIVE. The authors would like to reveal preoperative and intraoperative predictors of lethal outcome in patients with otogenic and rhinosinusogenic pyoinflammatory intracranial complications. The study assessed an efficacy of specialized medical care of this category of patients. MATERIAL AND METHODS. Тhis research included 303 patients (199 (65,68 %) men and 104 (34,32 %) women) aged from 39,3 ± 17,4 years on average who underwent operation concerning intracranial pyoinflammatory oto- and rinosinusogenic complications in multidisciplinary hospitals of different subjects of the Russian Federation at the period from 2000 to 2014. RESULTS. Multiple logit regression analysis of predictors of lethal outcome showed the presence of higher number of factors and errors which influenced on treatment during preoperative period. These factors and errors caused an extension of preoperative period and increase of unfavorable outcome. CONCLUSIONS. While planning the management of primary and specialized care, doctors should take into account the identified predictors for patients of this category.

Purpose – The purpose of this paper is to study the incidence of depression affecting work (DAW) performance and estimates gender differences across occupations. Design/methodology/approach – Using Labor Force Survey data from the UK in 2007, the authors first decompose the differential on the aggregate incidence rate of DAW between men and women into two components: the gender effect and the occupational effect. Then, the authors identify the stressors of DAW by means of a logit regression analysis. Findings – The empirical results show that gender is not a significant explanatory variable of DAW. Further, when differences are analyzed for each gender separately, results show that the effect of occupations is stronger within females than within males. Originality/value – Most of previous studies focus on occupational causes of depression. By contrast, this paper investigates the effect of depression on work performance.
