Dust Reduction

This study conducted a comparative analysis of the factors affecting the concentration of fine dust before and after COVID-19. Of these, the dominant factor was CO, and the influence between variables increased even after COVID-19. In the case of PM10, the influence of wind direction and wind speed variables decreased, which is thought to be due to the reduction of westerly-based foreign air pollutants following China’s containment policy. Comparative analysis by season showed that the influence of temperature and humidity was higher in winter. In spring, the influence of wind direction and speed decreased with changes in the westerly wind and the influence of China’s containment policy. In summer and autumn, when the concentration of fine dust is relatively low, the influence of CO after COVID-19 was rather high, indicating that continuous CO management is necessary. Considering the relationship between these air pollutants and the meteorological environment, it is judged that fine dust reduction measures should be implemented.

Macroeconomic Indicator

Subject. The working time of workers at any stage of economic development is a value reflecting the level of labor productivity. Any progress in productivity contributes to changes in the volume of labor costs and the number of employed. Depending on the relationship between the total volume of labor costs and the number of employed, the duration of working time per one worker may change (it may increase, decrease, or remain unchanged). Objectives. The study aims to confirm the importance of such a macroeconomic indicator as the number of employed in varying working hours. Methods. The study rests on the comparative analysis of countries with developed economies based on some indicators like dynamics of the working time fund, dynamics of the number of employed, average number of hours worked during the year per employee, etc. The analyzed timespan is 25 years (from 1991 to 2016). Results. The comparative analysis revealed that in the non-production sphere and the economy as a whole the macroeconomic determinants correlate so that the length of working time per worker reduces. When considering the analysis results for the manufacturing sector, no single trend was identified. Conclusions. One of the key factors affecting the change in working hours is the number of employed. The relationship between the working time fund and the number of employed directly determines the dynamics of working time per worker.

The Relationship

The relationship of socioeconomic factors to pregnancy experience and later neuropsychiatric functioning was investigated by a series of retrospective and anterospective epidemiologic studies. The studies demonstrated an increased amount of brain damage in the lower socioeconomic strata, where a higher incidence of complications of pregnancy and a greater number of babies with low birth weights are found. In 992 infants examined at 40 weeks of age, pregnancy experience, birth weight and later physical status were the only major factors which could explain group differences in developmental quotients. The studies further indicated that the relatively small amount of variability found in infancy could be explained largely by the presence of damage to the central nervous system, and supported the view that at this period of life social factors affect the psychologic level of integration primarily through biologic mechanisms. Later, during the preschool period, the direct influence of the sociocultural forces on the psychologic performance becomes manifest.

The aim of this study was to investigate whether differences in information and communication technology (ICT) readiness and access across countries were fundamentally related to the variable of English language adoption. A one-way multivariate analysis of variance (MANOVA) was utilized to comparatively examine the developments of ICT readiness and use among 149 countries categorized into four groups based on levels of English language adoption and economic development. The results of the comparative analysis showed that English language adoption is not a dominant factor in determining the global digital divide. The results suggest that much of the differences in ICT development across countries are attributable to levels of economic development. Limitations and implications for additional studies on specifying key factors widening the global technology gap are discussed.

Background. Until now, there have been no objective criteria to determine the activity of chronic pulmonary aspergillosis (CPA). This study aims to analyze the correlation between serum level of IL-1B and the activity of CPA and to determine whether serum IL-1B could be used to assess the activity of CPA. Methods. A total of 469 newly diagnosed CPA patients were enrolled. Correlation analysis in the whole subjects showed that only IL-1B level was associated with the activity of CPA. Then, 381 cases with factors significantly affecting IL-1B expression was excluded through multiple linear regression; the remaining 88 patients were divided into high IL-1B group and low IL-1B group, according to the median value of serum IL-1B, for subgroup analysis. A retrospective comparative analysis was subsequently performed between the two groups, including the clinical manifestation, microbiology and laboratory tests results, and imaging findings. We further investigated the relationship between IL-1B levels and CT characteristic which acted as the indicator of CPA activity, as well as changes in IL-1B level before and after surgery. Results. For all patients, correlation analysis revealed that IL-1B level correlated with both cavitary diameter (P=0.035) and aspergilloma size (P<0.047) but not with the thickness of the cavity (P=0.479). In subgroup comparative analysis, CT characteristics suggested that high activity of CPA, such as cavitary (27/44 vs 13/44, P=0.003) and aspergilloma lesions (25/44 vs. 11/44, P<0.002), were more frequently found in high IL-1B group. The cavity diameter (P<0.001), aspergilloma size (P=0.006), and cavity wall thickness (P=0.023) were significantly different between the two groups. When Spearman correlation analysis was performed once again in subgroup, an even stronger relationship of serum IL-1B with the cavity diameter (Rs=0.501, P=0.002) and aspergilloma size (Rs=0.615, P=0.001) was observed. Interestingly, a significant reduction of IL-1B level was observed after successful resection of CPA lesions. Conclusion. Higher level of serum IL-1B is associated with more severe cavitary and aspergilloma lesions, which are indicative of more active CPA. In addition, IL-1B level reduced accordingly after lesion resection. Measuring IL-1B level therefore could be served as a convenient method to monitor the activity of CPA and be a potential predictive/prognostic marker for treatment response.

The Church

Light levels in the churches of the Cistercian Order are mostly related to the fulfilment of liturgical needs. The compound building of Bernardas’ Convent includes a church at the utmost southern corner that dates back to the 17th century. It only has one façade facing due southeast. This paper analyses the relationship between daylight conditions within the building before and after the urbanisation of the surrounding area; taking into account the relationship between the church, its main activities, and solar trajectory. A comparative analysis of the relationship between the actual surrounding context and the initial period after it was built (open field) is given. The highest reflectance of the street canyon has augmented the levels of available daylight.

The Relationship

Neonatal viability is one of the key factors affecting piglets’ vitality, which ultimately affects the survival and growth of piglets (England, 1974). As colostrum is the only food resource of neonatal piglets, their ability to acquire the colostrum as early as possible after their birth can determine their vitality. Piglets are usually supplied with creep food at some time during the suckling period in order to improve their performance before and after weaning. However, the creep food intake varies between litters and between individuals. Furthermore, the relationship between viability in early life and the acceptance of a new food (e.g. creep food) when they first encounter it, is not fully understood. The objectives of this study were to investigate factors affecting the neonatal viability of piglets at birth and to identify the relationship between neonatal viability and subsequent creep feeding behaviour by piglets on d14-d15.

The Relationship

This experiment investigated the relationship between mental rotation and sport training. Undergraduate university students (n = 62) completed the Mental Rotation Test ( Vandenberg & Kuse, 1978 ), before and after a 10-month training in two different sports, which either involved extensive mental rotation ability (wrestling group) or did not (running group). Both groups showed comparable results in the pretest, but the wrestling group outperformed the running group in the posttest. As expected from previous studies, males outperformed women in the pretest and the posttest. Besides, self-reported data gathered after both sessions indicated an increase in adaptive strategies following training in wrestling, but not subsequent to training in running. These findings demonstrate the significant effect of training in particular sports on mental rotation performance, thus showing consistency with the notion of cognitive plasticity induced from motor training involving manipulation of spatial representations. They are discussed within an embodied cognition framework.

This paper investigates factors affecting Vietnam’s stock prices including US stock prices, foreign exchange rates, gold prices and crude oil prices. Using the daily data from 2005 to 2012, the results indicate that Vietnam’s stock prices are influenced by crude oil prices. In addition, Vietnam’s stock prices are also affected significantly by US stock prices, and foreign exchange rates over the period before the 2008 Global Financial Crisis. There is evidence that Vietnam’s stock prices are highly correlated with US stock prices, foreign exchange rates and gold prices for the same period. Furthermore, Vietnam’s stock prices were cointegrated with US stock prices both before and after the crisis, and with foreign exchange rates, gold prices and crude oil prices only during and after the crisis.
