. In the context of rapid urbanization, pollution and ecological degradation problems have frequently shown up and influenced environmental sustainability of rural China in the past decades. The rural residents have begun to pay attention to local environment protection, and researchers have been taking public perceptions into regional planning. However, comprehensive studies on the perceptions of villagers on rural environment development still remain less. This research carried out a face-to-face questionnaire investigation of 187 villages and ten residents from each village at a nationwide scale of China. The investigated village committee managers and residents were interviewed by asking the questions including the existing environmental problems, the targets of rural environment development, the ways to achieve these targets and the willingness to pay for pollution control. The results showed that household waste pollution, air pollution and pesticides pollution etc. are top concerned problems. A big proportion (65%) of the interviewed residents chose “environment with good quality for health” as their preferred living environment. While, more than half of the interviewed village managers took “green villages with sustainable agriculture” as their village development targets. And more than 50% of the interviewed residents advocated to increase the forest coverage rate to mitigate the degeneration of rural ecosystem services. As well, most residents strongly support rural green development and are willing to pay for pollution control. Our findings may provide new insights into rural environment development and rural revitalization in the context of rapid urbanization.

Mangrove forests are an important part of tropical coastal ecosystems. Until recently, these forests were intensively exterminated. Currently, the issue of mangrove conservation is being discussed at a number of symposiums due to their significant role in reducing the effects of greenhouse gas emissions. However, there has recently been uncertainty in estimation of CO2 fluxes in mangrove forests due to a lack of field research. The results of studies of photosynthesis at the leaf level in-situ in seedlings of Rhizophora apiculata Blume, 1827 of both natural and artificial origin are presented. The studies were carried out on a mangrove plantation growing in Can Gio Mangrove Biosphere Reserve, which is 50 kilometres from Ho Chi Minh City (South Vietnam). CO2 gas exchange during photosynthesis was measured using a gas analysing system called the LI-6800 (USA). Photosynthetically active radiation (PAR) is the main factor affecting the photosynthesis of the studied seedlings. Artificial seedlings that were grown in open areas had higher productivity and greater photosynthetic rates. It has been determined that the measured photosynthesis are scattered over three clearly marked zones, which correspond to the measurements of photosynthesis made in the pre-noon, noon and afternoon hours. The water reserves used up before noon were not fully replenished in the afternoon by the seedlings. Based on the results obtained, it has been suggested that the main inhibitory factor affecting the photosynthesis of R. apiculata (if PAR is not taken into account) is a violation of the water balance of the leaves.The optimum air temperature for photosynthesis processes in seedlings is (35 ± 2) °C. The intensity of photosynthesis also increases with an increase in the concentration of CO2 in the air. The increases of photosynthesis continue until the concentration of CO2 reaches ~1000 µmol·mol-1 and then do not increase. We associate this circumstance with the maximum possibilities of the photosynthetic apparatus of the leaf of the studied plant. The obtained research results will contribute to a better theoretical understanding of the productivity of plants of this species in the respective ecosystems, and will also allow us to move from photosynthesis at the leaf level to photosynthesis at the planting level. The work’s mathematical models can be used to model changes in R. apiculata photosynthesis from the point of view of climate change.

The urban sprawl of cities periphery is one of such changes that has led to drastic land-use changes, which resulted in landscape fragmentation. The objective of this study is to understand the process of landscape fragmentation because of urban expansion; identifying the most influential drivers that have changed the land-use. To achieve the objectives due to changes in land use, a study had conducted in Ramallah area of Palestine. The study utilized Fragstat software to quantify the landscape changes with regard to its pattern and structure through a number of indices, also using Geographic Information System tool to draw up different landscape parcels spatially with its characteristics. The spatial analysis carried out on the land-use change used the 1997 and 2017 aerial photos to quantify the landscape fragmentation, which included a variety of land-uses. Over 52% of the study area underwent noticeable urbanization process, resulting in appreciable landscape changes to the area, especially after 1993. The statistical analysis of the landscape fragmentation revealed significant changes in land-use during the period from 1997 to 2017; the green landscape has been fragmented at a large scale by increasing the number of landscape patches (from 71 to 148 patches). As a result, there was an obvious reduction in agricultural lands, such as olive groves and grassland. At the same time, the urban surface areas increased from 654 patches in 1997 to 2019 patches in 2017. These results indicate that the landscape has become more fragmented due to geopolitical and socio-economic drivers since mid-1995 after Oslo accord.

Human health is harmed by air pollution. The objective of this research was to show that air pollution in Pakistan is getting worse and is negatively impacting people’s health. IQ Air and the Institute for Health Metrics and Evaluation provided the data for this descriptive research. Monthly data of PM2.5 μg/m³ from ten different localities across Pakistan are used to show spatial distribution through the geospatial technique of interpolation. The findings show that two third of the country has high PM2.5 concentration, with Lahore as the most polluted city. In Pakistan, solid fuel use has decreased, leading to a decline in associated mortality and morbidity. However, there have been significant increases in PM2.5 and ozone levels, resulting in a rise in the country’s overall health burden caused by air pollution. Furthermore, the number of deaths attributed to air pollution has also increased since 1990. A total of 57% of chronic obstructive pulmonary disease, 40% of lower respiratory infections, 36% of ischemic stroke, 35% of ischemic heart diseases, 32% of lung cancer, 25% of diabetes, and 20% of neonatal outcomes are directly attributed to air pollution in Pakistan. The main contributors to air pollution are population growth, growing motorization, and unsustainable energy usage. The main challenges due to air pollution control and monitoring in Pakistan include a lack of awareness, poor policy creation and implementation, the use of improper fuel, rising energy demands, and an absence of pollution monitoring stations in most cities. Therefore, there is a need for a robust air pollution monitoring system, increased public awareness, and the implementation of clean and sustainable policies to regulate this environmental health issue.

Abstract
This research was conducted to identify the humanistic approach of Abraham Maslow's theory in cooperative learning in social studies subjects in class V by focusing on Abraham Maslow's 5 needs regarding the achievement of each need. The method used was qualitative method with descriptive analysis. Data were obtained through interviews, observation, and documents. The results of this research indicated that physiological needs, social needs, needs to be appreciated, and self-actualization needs have not been properly actualized, this is because: (1) teachers were still lacking in the mastery of cooperative learning techniques, (2) the atmosphere was unconducive, and the students were less compact in completing assignments, (3) students had not yet developed a sense of appreciation, so they still needed teacher instruction, and (4) some students could not express the material studied in class. The need for a sense of security had been implemented properly because the teacher gave the freedom to ask, answer, and accept the opinions expressed by his/her students.

Published: June 2023

Tafsir telah mengalami perkembangan secara metodologis dan subtansial, kehadiran aliran tafsir bi al-ma’tsur dan bi al-ra’yi turut memberi warna bagi pemikiran umat muslim. Di sisi lain, ada persoalan cukup serius di bagian tafsir bi al-ma’tsur, yaitu dengan hadirnya varian riwayat, dari riwayat yang sahih hingga riwayat yang tidak bisa dipertanggung jawabkan menurut parameter sanad dan rijal hadis dalam disiplin ilmu hadis. Metode penyajian yang diterapkan Imam al-Thabari adalah dengan memilah-milah beberapa ayat al-Qur’an. Misalnya dalam satu surah, ayatnya dibagi menjadi beberapa bagian, kemudian dalam satu ayat dipenggal menjadi beberapa kata, dan setelah itu baru kemudian Imam al-Thabari memberikan pembahasan secara rinci dengan memberikan penjabaran kosa kata, aspek gramatikal, aspek qira’ah, menyebutkan asbab al-Nuzul (bila ada), menyebutkan berbagai pendapat ulama dan mentarjihnya.

Published: June 2023

In the digital era, learning history is more directed at reviving students' divergent thinking power. By applying this different way of thinking, teachers can use historical resources available on the internet. This research uses a Systematic Literature Review (SLR) to examine the idea of divergent thinking in exploring students' creative efforts in reading historical sources from the internet. Based on the results of the concept of developing different ways of thinking about historical sources, this is a form of student creativity to imagine the work of historians in using and evaluating historical sources to write history. Students can already see how ideas, especially initial ideas, that students share with historical sources shared by the teacher can lead to creative actions. And these results can be used as a benchmark for teachers on how to teach history based on the level of thinking ability and the way students learn.

THE IMPACT OF LEARNING ASSESSMENT EMERGENCY ON THE EDUCATION QUALITY
Authors: Ikhrom Ikhrom 
Published: June 2023

The learning process that switches to the online system requires the enactment of assessment emergencies in various schools. This study aims to determine the assessment process of student learning during Covid-19, the impact of emergency assessment on student conditions during learning, and the implications of emergency assessment on the quality of education. This research method is a mixed method with a phenomenological approach. The instruments used are in the form of questionnaires and interviews. The results of this study show that the emergency assessment was carried out not optimally. The implementation of emergency assessments leads to a decrease in motivation, participation, understanding, and changes in the way students learn. This makes the quality of learning during the Covid-19 period worse. There has been a decline in student motivation, learning achievement, and morals, as well as a cumulation of competency standard (KD) loads at the next level.

Progress in plant tolerance to the fungal disease Sclerotinia in breeding experiments on winter oilseed rape
Authors: Zawieja Bogna , Slebioda Laura , Mikulski Tomasz 
Published: June 2023

Summary

Sclerotinia sclerotiorum is a pathogen which causes a disease of oilseed rape. Severe plant infection contributes to a decrease in the quality of the crop. It is therefore important to pay attention to whether hybrids are highly tolerant to this fungal disease at the early stages of breeding. In this study, the question of interest is whether there has been progress in increasing the tolerance of new hybrids to this pathogen. Three years of breeding experiments (2014, 2015, 2017) are included in the analysis. Each year, three to five experiments were carried out, with several dozen varieties and three standards. Each series of experiments was repeated in several locations. Because the degree of infection was assessed on a scale (from 1 – the highest infection – to 9 – the least infection), the analysis is carried out using an ordinal logistic model. It is noted that in earlier years the standard varieties’ probability of infection with this disease had a smaller range (empirical probability 0.5–0.83) than in the last analyzed year (empirical probability 0.33–1.00). The results of the analysis show that in 2014 and 2015 several hybrids exhibited a significantly higher tolerance to Sclerotinia, but in 2017 none of the hybrids were significantly better than the standard. Perhaps breeding selection of hybrids has eliminated the less tolerant varieties. However, to be able to draw more general conclusions, it would be necessary to repeat the study in controlled conditions (a greenhouse), where the level of fungal spores and their effect on plants could be controlled. Obtaining tolerant hybrids will enable a reduction in production costs, since there will be no need to monitor whether disease infestation occurs and no need to use corresponding plant protection products.
Univariate and Multiple Regression Analyses in Medical Research
Authors: Poon Ethan , Feng Changyong 
Published: June 2023

Summary
Regression analysis methods, such as linear regression for continuous outcomes and logistic regression for binary outcomes, have been widely used in medical research data analysis for many years. However, there have been instances of misconceptions and misinterpretations of regression results within the medical community. Univariate and multiple regression analyses are commonly used by medical publications to identify factors that are significantly correlated with the outcome. In this manuscript, we critically evaluate the validity of this approach. Our findings indicate that this method is invalid and should be completely disregarded by medical researchers.
