Supply Shock

This study decomposed shocks of the global crude oil (GCO) market and Korean gasoline (KG) market into six types using the structural vector auto-regressive model. Breaking down the shocks into six, we analyzed how each shock affects the macroeconomy and gasoline market in Korea. Results of the analysis revealed that the oil supply shock did not cause a large fluctuation in gasoline prices, but it harmed the macroeconomy. By contrast, the two shocks on the demand side of the GCO market caused a large increase in domestic gasoline prices, but they did not negatively affect the macroeconomy. Meanwhile, in the KG market, gasoline-refining shock and gasoline demand shock caused a significant increase in gasoline prices. Both shocks had some negative effects on the Korean macroeconomy at a certain point, but the effects are not as strong as the oil supply shock. However, the gasoline distribution shock in Korea rarely caused negative consequences for major macroeconomic variables. Moreover, analyzing the KG prices through historical decomposition, we found that the two demand-side factors of the GCO market and the demand shock of the KG market have had the most important influence on the gasoline price since the 2000s. From the analysis, the increase in gasoline prices in Korea since the 2000s can be inferred to have no significant negative impact on the macroeconomy. Therefore, the essential factors of price fluctuations must be focused on in analyzing domestic gasoline price and their impact on the macroeconomy.

In the spring 2020, the first wave of the coronavirus pandemic quickly spread across Finland, having significant negative consequences for people’s living conditions. On March 16, 2020, the Finnish government declared a state of emergency and imposed several restrictive measures that were in effect until July 16, 2020 [13; 16]. The coronavirus and its aftermath have weakened the resilience of the Finnish welfare state, thereby challenging the welfare state’s ability to protect those most in need of its support. Recent studies have shown that the most vulnerable populations, such as children, are most affected by the negative effects of the pandemic in Finland and worldwide [5; 9; 11; 14; 18]. In autumn 2020, the Central Union for Child Welfare (CUCW) and the National Institute for Health and Welfare (THL) conducted a large-scale survey among the heads of child protection authorities (15.08.—13.10.2020), the aim of which was to find out how the consequences of the coronavirus and government restrictions have affected the well-being of children and their families who are clients of child protection authorities during the fall 2020. This article presents the main results and conclusions of the survey.

AbstractThe link between crude oil price and stock returns of the Group of Seven (G7) countries (Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States) was analyzed in this study using monthly data from January 1999 to March 2020. We adopt a similar approach to Kilian (Am Econ Rev 99(3):1053–1069, 2009) and construct a structural vector autoregression framework to decompose crude oil price shocks into oil supply shock, oil aggregate demand shock, and oil-specific demand shock. We then explore the distinct effects of different kinds of oil price shocks from various sources. Based on the decomposed oil price shocks, we apply the connectedness approach and QQ regression to find time-varying co-movements and tail dependence between oil price shocks and G7 stock returns. There is no general correlation between the decomposed oil prices and stock returns in these countries. The effects of oil price shocks on stock returns across different stock market conditions appear to be heterogeneous. Oil supply shock appears to be a net transmitter of spillover effects for all G7 countries within the sample period.

Effective Contraceptive

Considering the activity level of a modern woman and her desire for self-development and self-realization, she independently regulates and chooses the time that, in her opinion, is the most favorable for creating a family and having a child. Considering the fact that in most cases women use contraceptives to regulate pregnancy and childbirth, the issue of selecting the most effective contraceptive without negative consequences or health disturbances including reproductive system becomes extremely relevant. The purpose of this review is to identify contraceptives that, according to medical researchers and gynecologists, have minimum or no negative impact on women's health and yet help to prevent pregnancy. The analysis of WHO recommendations and conclusions made by both Russian and foreign researchers, including Yaglov V.V., Crosignani PG, H.K. Kallner, K. G. Danielsson and others during the past 10 years, has identified contraceptives with minimum negative effects and the highest possible effectiveness. Based on the conducted literature review, the following main groups of contraceptives have been identified and classified: hormonal (combined estrogen-gastrogenic drugs, mini-pills, injectable drugs, subcutaneous implants, hormonal, etc.) barrier (vaginal diaphragm, cervical cap, contraceptive sponge); biological methods (temperature method, cervical method, symptothermal method). The study showed that hormonal-type drugs turned out to have the highest effectiveness (99.9%) with negative consequences including hormonal disruptions, excess weight gain, and cancer development in rare cases. Regardless of the contraceptive type selected, the woman should first undergo a medical examination and consult a gynecologist who will tell which contraceptives are most appropriate in each case. Most researchers in the field of medicine and gynecology agree that the safest and most effective contraceptive method is male barrier contraceptives - condoms that do not have a negative effect on the female health, except for possible allergic reactions to lubricants used by the manufacturer.

Abstract The pandemic of COVID-19 has caused a global crisis. Today, everybody focuses on COVID-19 infection prevention, preparation, and discussion of physical health effects issues. It is important to understand, however, that a few will face life-threatening negative effects on physical health, but that all people will face the negative impact of the pandemic on mental health. COVID-19 hospitals are established in different locations to address the physical health implications of the pandemic. However, it is necessary to understand the effects of infections on mental health more effectively to prevent the negative consequences of infection. Here, we try to find out how the infection could affect mental health. We identify motifs in SARS-CoV-2 that are predicted to interact with human transcription factors (TF). Those TFs regulating behavior and mental health. Our results show that SARS-CoV-2 infection may lead to overactivation or inhibition of critical genes already known to affect behavior and mental health. This study is still limited to in silico limits so, clinical investigation needs to be addressed to assess our hypothesis.

The presented study addresses the problems of development of small and medium towns in Russia. Aim. The study aims to examine a town as a socio-economic environment where its residents exist and as the fundamental factor for the development of society.Tasks. The authors identify key problems in the development of small and medium Russian towns, which interferes with the historical appearance and has a negative impact on the living environment.Methods. Problems in the development of small and medium towns in Russia are examined using theoretical methods: systematic approach, statistical analysis, social and philosophical analysis.Results. The study identifies the main negative effects of the existing model of development of small and medium Russian towns, such as destruction of their historical and cultural appearance, distortion of the overall architectural motif, increased load on communications, and congestion of the transport infrastructure.Conclusions. At the current stage, efficient development of small and medium towns in Russia is impossible within the framework of the existing infill development. This chaotic process cannot be stopped without a new conceptual approach and changes in the legislative and normative framework of urban development. The only factor that determines the boundaries of the existing approach to urban development is the lack of physical space for new buildings in urban areas. The authors formulate proposals that would help to solve the problems of development of small and medium towns in Russia.

AbstractThe 2011 National Nutrition Survey of Pakistan revealed that 51% of the country’s population was consuming less than 2,100 calories a day. In the backdrop of rising food insecurity, hunger, and malnutrition in Pakistan, this study aims to measure the effects of indirect taxation on health outcomes of children (<5 years). More specifically, the impact of the incidence of General Sales Tax (GST) in the province of Punjab has been estimated on a child’s height and weight. The proponents of the uniform GST argue that the tax would not affect children because most food items consumed by children are exempted from the GST. However, the opponents believe that households, especially those belonging to the lower-income group, would reallocate resources away from children in the face of higher GST. To study these effects, we utilized three different waves (2007–08, 2011 & 2014) of Multiple Indicators Cluster Surveys (MICS). The results show that the tax incidence, and not the GST rate, has a significantly negative impact on children’s height-for-age Z-score (HAZ). No effect was found on the weight-for-age-z-score (WAZ). These results are robust to different specifications and exhibit considerable heterogeneity across different income groups. These findings suggest that the exemption of certain food items for children from the GST may not eliminate the negative effects of this tax on a child’s health. Thus, our study raises concerns about the long term welfare consequences of GST.

Abstract Purpose We conducted a retrospective observational study in order to identify negative effects of NOTES procedures (Natural Orifice Transluminal Endoscopic Surgery) with transvaginal specimen removal on pregnancy and delivery. Methods From the total population of 299 patients in our NOTES registry, we tried to contact the 121 patients who were of reproductive age (≤ 45 years) at the time of a transvaginal NOTES procedure. They were interviewed by telephone regarding their desire for children, post NOTES-operation pregnancies, and type of delivery using a structured questionnaire. The collected data was analyzed and compared with current data. Results We were able to contact 76 patients (follow-up rate: 62.8%) with a median follow-up of 77 months after surgery (33–129 months). Twenty of 74 participating patients had a desire for children (27.0%). One of them and another's male partner were diagnosed as infertile. Regarding the remaining 18 patients, 14 became pregnant, and three of them became pregnant twice. Considering these 17 pregnancies, there was one miscarriage (5.9%) and one twin birth (5.9%). On average, childbirth occurred 44 months after the NOTES procedure. With regard to the type of delivery, 10 vaginal births (58.8%) and 7 caesarean sections (41.2%) occurred. Thus, the rate of fulfilled desire for children was 77.8%. Compared with the literature, no difference to the normal course could be detected. Conclusion There is no sign that the transvaginal approach in Hybrid-NOTES, with removal of the specimen through the vagina, has a negative effect on conception, the course during pregnancy, or the type of delivery.

The following research focuses on the possibility of applying fresh plant material as a carrot pulp to supplement newly developed extruded products in the form of pellets and microwave-expanded snacks. Fresh carrot pulp, as a valuable vegetable ingredient, was used in the amount of 2.5 g/100 g to 30.0 g/100 g in a potato-based recipe. The snack pellets were processed via extrusion-cooking, using a single-screw extruder with a plasticizing unit L/D = 18, and the use of variable screw speeds. The produced pellets underwent microwave expansion to limit the fat content, so as to produce ready-to-eat (RTE) snacks. The pellets and snacks were tested for nutritional value, as well as for selected quality features: physical properties, structure, pasting characteristics, and texture profile, and PCA analysis and a correlation matrix were performed on the obtained results. Microwave expansion of pellets increased the total phenolic content, the antioxidant activity, water absorption index and lightness of snacks, but decreased the bulk density and setback values of the expanded products when compared to pellets. Generally, we found that it was possible to use up to 30.0 g/100 g of fresh carrot pulp with a positive effect on nutritional value, and without negative effects on the physical properties of extruded products. Both the extrusion-cooking and microwave expansion can minimize the negative impact on plant materials, due to the short processing time.
