Investigation on the Ignition of Self-Regulating Heating Cables due to Overheating

Owing to the self-regulating heating cables installed to prevent freeze-up, hundreds of fires are reported annually. According to the Fire Statistical Yearbook of 2020, provided by the National Fire Agency of Korea, a total of 2,245 fires occurred due to seasonal equipment, of which 240 were caused by heating wires. It is reported that the fires due to the self-regulating heating cables are mainly caused by short circuit, heat storage, poor contact, and electric leakage. Herein, the possibility of ignition in self-regulating heating cables owing to overheating is investigated. Test samples were prepared according to the IEC 60738 standard, and the resistance characteristics and surface conditions were analyzed at varying temperatures. It was found that the self-temperature control function of these cables was lost at a specific temperature. In addition, the ignition of self-regulating heating cables was confirmed through a fire reproduction test at the experimental temperature.

ДОБРОБУТ СЕЛЯН У ПОСТРАДЯНСЬКИЙ ПЕРІОД

Ключові слова. побут, селянство, матеріальний добробут, інфраструктура, медицина, культура, освіта. Анотація У статті розглянуто особливості добробуту сільського населення у пострадянський період. Акцентується увага на забезпеченості населення необхідними для життя матеріальними благам. Насамперед, продуктами харчування, промисловими товарами, послугами та умовами, що задовольняють певну потребу людини і відповідають її інтересам. У не найкращому стані перебувала соціальна сфера, комунальне господарство і медицина. Кризові явища, якими супроводжувалися трансформаційні процеси в економіці, завдали відчутних збитків матеріальному забезпеченню селян. За результатами зібраних матеріалів доведено, що економічна криза, швидкі темпи інфляції, проблема дефіциту товарів, затримка коштів для виплати заробітної плати в 90-х рр. ХХ ст. ускладнювали матеріальне становище сільського населення України. Посилання Bakhovskyi, 2003 ‑ Bakhovskyi V.

Yields variability as a determinant of production risk in agriculture

Agricultural activity is exposed to a number of adverse external factors known as production risks, which affect the quantity and value of production. One of the measures of production risk assessment in crops production is yields variability. The aim of the study is to determine the scope of the variability of the yields of selected agricultural crops on the basis of various sources of data covering the years 2015–2019. The study uses aggregated official statistics data compiled by Statistics Poland, published in the Statistical Yearbook of Agriculture, and individual data from the Polish Farm Accountancy Data Network (FADN), which takes into account commercial farms. The analysis of the differences in crops variability determined on the basis of different sources of information was carried out using basic statistical parameters: the arithmetic mean, standard deviation and the coefficient of variation. The research shows that the variability of yields in Poland depends not only on the type of crops, but also on the location of the production. Moreover, it indicates a greater stability of crops production among commercial farms when compared with farms in general. The comparison of the values of the coefficient of variation calculated from individual data with the values calculated on the basis of the average yields indicates fundamental differences which should be taken into account when applying the variation coefficient to assess production risk and, consequently, to optimise insurance tools.

The Spatial and Temporal Characteristics of Industry–University Research Collaboration Efficiency in Chinese Mainland Universities

The aim of this study was to investigate the spatio-temporal characteristics of the industry–university research (IUR) collaboration efficiency of Chinese mainland colleges and universities, from 2008 to 2018. A comparative analysis method was used to analyze the data from the Statistical Yearbook of China’s Education Funds, the Compilation of Science and Technology Statistics of Colleges and Universities, and the China Statistical Yearbook. The principal components were extracted from relevant indicators of IUR capability in colleges and universities, with a principal component analysis (PCA) method. The principal component scores and comprehensive scores of 31 provinces in mainland China were calculated. The results showed that the efficiency of IUR collaboration in Chinese colleges and universities has increased rapidly within the 11 years studied. The efficiency in the eastern region has grown faster than that in the western region, and the gap between the southern region and the northern region has also continued to widen. The results also showed that the development of IUR collaboration efficiency of colleges and universities in mainland China is unbalanced. Scientific and technological funds, and scientific and technological manpower, were excessively concentrated in the southeast. Therefore, there is large room for improvement in the overall development of IUR collaboration in Chinese colleges and universities.

INTEGRASI REGIONAL: ARUS INVESTASI DAN IMPLIKASINYA TERHADAP PENERIMAAN PAJAK

The ASEAN Economic Community (AEC) has been established for several decades. The AEC is inspired by other regional communities. The situation strengthens each country’ economic and investment. Based on ASEAN Statistical Yearbook 2020, in 2019 the capital inflow to ASEAN amounted USD 158 Billion. The objective of this study is to investigate the cause and effect of these global phenomenon to ASEAN countries especially Indonesia. Also, this paper will elaborate FDI effect from the tax revenue point of view. This paper uses a qualitative method in order to obtain a deep understanding. We found several findings. First, there is a relation between the establishment of regional community and foreign direct investment (FDI). Second, FDI is beneficial to enhance the tax administration system especially country’s tax revenue.

Modelling the Spatial Distribution Differences of Compulsory Education Resource

This paper aimed to explore the difference in the spatial distribution of compulsory education resource allocation. Raw data were collected from the 2020 China Statistical Yearbook (county/district level) and Guangxi Province Statistical Yearbook of China. Data analysis was conducted using the entropy method, comprehensive evaluation method, K-means clusters analysis, analysis of variance, and spatial statistical analysis (Moran’s I index). It was determined that there were significant differences in the spatial distribution of compulsory education. The equilibrium degree to mandatory education resource allocation was divided into three classes: high level, medium level, and low level, and each class presented a spatial aggregation effect in the spatial distribution. Compared with the primary schools, the equilibrium degree of junior secondary school was higher. However, the equilibrium fluctuation of junior secondary schools was more significant among different counties/districts. The equilibrium of educational resources of junior secondary schools in the urban areas was higher than that in the rural areas, but there was no significant difference for the primary school.

Impacts of the Blue Economy on Economic Growth in Vietnam

This study evaluated how factors of the blue economy affect economic growth employing the quantitative method to run a panel regression model, based on data collected from sources from the General Statistics of Vietnam (GSO), the General Department of Vietnam Customs, Vietnam Statistical Yearbook....with a sample of 280 observations from 28 coastal provinces and cities in Vietnam from 2010 to 2019. The contributing factors that measure the blue economy growth are total fishery production, aquaculture production, shipping and port, travel and tourism, labour, capital and export. The results revealed that the blue economy factors played a significant role in Vietnam's economic growth. In addition, the study proposed that it was necessary to build stable politics, clear orientations, reasonable control over investment sources, and national cultural spirit to improve and develop a sustainable blue economy.
