Aim. The aim is to assess the environmental threats to Park forest ecosystems and to study the possible links and the long-term consequences of their actions. Methods. Methods use of comparative analysis, classification, ranking of impacts, mathematical processing of data. Results. The main threats to Park forest ecosystems are formulated and evaluated. Deepened some of the methodological effects on criteria for assessment of threats. The classes of danger are defined, the General danger index of threats and correlation communications between groups and criteria of their assessment is calculated. The factors that have the most negative impact on the biodiversity of parks. Conclusions. In the conditions of urban ecosystems there is a strengthening and lengthening of the action of some threats and leveling of other types of impacts. The characteristics of the intensity of action, the time factor and the spatial spread of threats do not have a clear synchronization. The overall hazard index showed the dominance of the intensity and time of the impact of specific threats to the urban ecosystem. Keywords: anthropogenic impact, General hazard index, urban ecosystem, biodiversity.

BACKGROUND: China’s atmospheric PM2.5 pollution is serious, and PM2.5 exerts a negative impact on the human respiratory system, cardiovascular, and mental health, and even more serious health risk for the elderly with weak immunity. OBJECTIVE: This work aims to analyse the impacts of PM2.5 microenvironment exposure on the health of the elderly and provide corresponding countermeasures. METHODS: The survey subjects are 118 retired elderly people in the community. PM2.5 exposure concentrations are monitored in summer (June 10 ∼ July 10, 2019) and winter (November 25 ∼ December 25, 2019). RESULTS: The exposure concentration in winter is higher than that in summer, with statistical difference (P <  0.05). Under the impact of PM2.5 microenvironment exposure, smoking in the elderly can increase the concentration of PM2.5, and long-term exposure to PM2.5 in the elderly can cause mental health problems. CONCLUSION: Long-term exposure of the elderly to the PM2.5 microenvironment leads to physical diseases and even psychological problems, which requires attention.

Bullying is deliberate aggressive action, using an imbalance of strength physically or mentally by hurting physical, verbal, or emotional / psychological forms repeatedly. In the last decade, cases of bullying in Indonesia continue to increase and if not handled properly will increasingly have a negative impact on the development of the children of the nation's next generation. Bullying does not only affect children who are bullied but can also affect children who bully, children who witness bullying. Some of the effects of bullying include anxiety, depression, and low self-esteem. The purpose of community engagement is to socialize the impact of bullying and how to increase self-esteem to adolescents. Through psychoeducation programs in adolescents such as schools and teenagers religious communities in the Cikarang - Bekasi region, young people gain an in-depth understanding of bullying, its effects and how to increase their confidence. Through this psychoeducation, teenagers understand the understanding, types and effects of bullying both short term and long term so they promise to resist bullying starting from themselves. Teenagers learn that humans are social beings who need each other. They learn about the meaning of diversity and bhineka tunggal ika and try to implement it in their next lives by respecting the differences in their environment. These teenagers learn to respect themselves more, see the positive things that God has given them. They try to always believe in themselves that they are perfect and valuable beings in God's eyes so that even though the environment around them may not appreciate, they can still see positive things in themselvesABSTRAK:Bullying adalah tindakan agresif yang disengaja, menggunakan ketidakseimbangan kekuatan secara fisik atau mental dengan cara menyakiti bentuk fisik, verbal, atau emosional/ psikologis secara berulang – ulang. Dalam satu decade terakhir, kasus bullying di Indonesia terus meningkat dan bila tidak ditangani dengan baik akan semakin berdampak negative bagi perkembangan anak – anak generasi penerus bangsa. Tindakan bullying tidak hanya berdampak pada anak yang di-bully tetapi juga dapat berdampak pada anak yang mem-bully, anak yang menyaksikan bullying. Beberapa dampak bullying diantaranya kecemasan, depresi, serta rendahnya harga diri (self-esteem). Tujuan dari pengabdian kepada masyarakat ini adalah untuk mensosialisasikan dampak bullying serta cara meningkatkan self-esteem kepada para remaja. Melalui program psikoedukasi di lingkungan remaja seperti sekolah maupun komunitas keagamaan remaja wilayah Cikarang – Bekasi, para remaja mendapatkan pemahaman mendalam mengenai bullying, dampaknya serta bagaimana cara meningkatkan kepercayaan diri mereka. Melalui psikoedukasi ini, para remaja memahami pengertian, jenis serta dampak bullying baik jangka pendek maupun jangka panjang sehingga mereka berjanji untuk bersikap menolak bullying mulai dari diri mereka sendiri. Para remaja belajar bahwa manusia adalah mahluk social yang saling membutuhkan. Mereka belajar tentang makna keberagaman dan Bhineka Tunggal Ika serta berusaha mengimplementasikannya dalam kehidupan mereka selanjutnya dengan cara menghargai perbedaan yang ada di lingkungannya. Remaja ini belajar untuk lebih menghargai diri mereka, melihat hal positif yang telah diberikan Tuhan kepada mereka. Mereka mencoba untuk selalu menanamkan dalam diri bahwa mereka adalah mahluk yang sempurna dan berharga di mata Tuhan sehingga walaupun lingkungan di sekitar mereka mungkin tidak menghargai, mereka tetap dapat melihat hal positif dalam diri mereka.

Purpose This paper aims to analyze the impact of COVID-19 on the trade of goods and services in Spain. Design/methodology/approach This paper uses monthly trade data at the product, region and firm level. Findings The COVID-19 crisis has led to the sharpest collapse in the Spanish trade of goods and services in recent decades. The containment measures adopted to arrest the spread of the virus have caused an especially intense fall of trade in services. The large share of transport equipment, capital goods, products that are consumed outdoors (i.e., outdoor goods) and tourism in Spanish exports has made the COVID-19 trade crisis more intense in Spain than in the rest of the European Union. Practical implications The nature of the collapse suggests that trade in goods can recover swiftly when the health crisis ends. However, COVID-19 may have a long-term negative impact on the trade of services that rely on the movement of people. Originality/value It contributes to understand how COVID-19 has affected the trade in goods and services in Spain.

The effect of reindeer Rangifer tarandus L. grazing on the ground-dwelling spider assemblage in Northern Finland was studied. Changes in species richness, abundance and evenness of spider assemblages were analyzed in relation to changes in vegetation and environmental factors in long term grazed and ungrazed sites as well as sites that had recently switched from grazed to ungrazed and vice versa. Grazing was found to have a significant impact on height and biomass of lichens and other ground vegetation. However, it seemed not to have an impact on the total abundance of spiders. This is likely caused by opposing family and species level responses of spiders to the grazing regime. Lycosid numbers were highest in grazed and linyphiid numbers in ungrazed areas. Lycosidae species richness was highest in ungrazed areas whereas Linyphiidae richness showed no response to grazing. Four Linyphiidae, one Thomisidae and one Lycosidae species showed strong preference for specific treatments. Sites that had recovered from grazing for nine years and the sites that were grazed for the last nine years but were previously ungrazed resembled the long term grazed sites. The results emphasize the importance of reindeer as a modifier of boreal forest ecosystems but the impact of reindeer grazing on spiders seems to be family and species specific. The sites with reversed grazing treatment demonstrate that recovery from strong grazing pressure at these high latitudes is a slow process whereas reindeer can rapidly change the conditions in previously ungrazed sites similar to long term heavily grazed conditions.

Abstract Assessment activity and surveillance of the forests health, held at the global, regional and local level, has continuously developed, culminating in the current period with interdisciplinary and extensive scientific researches, that evaluate the effects of the main factors on forest ecosystems state, in particular, air pollution and climate change. Scientific researches have shown that among trees ecophysiological processes, forest life processes and meteorological parameters there are direct dependences, particularly in the case of trees supply with water during the growing period (May-July), with major influences for critical months (July and August), which have a decisive impact on growth, vitality and production of organic matter in forests. Dry years, from the beginning of the third millennium can lead to a decrease of mesophilic forests area (beech, sessile oak and penduculate oak), which will tend to retreat towards the center of the area (central Europe) in favor of thermophilic forests with pubescent oak. It was determined that a most significant negative impact of climate aridization will feel the forest ecosystems from Southern and central regions of country (conditioned by the mean air temperature (July-August), monthly rainfall (May-August), evapotranspiration and geographic latitude), and less - the Northern part of the country (Forestry Aridity Index calculated for 3 experimental stations revealed variations of this index between 7.8 - 8.3 - in the Central part of country, and 8.4 - 8.6 - for Southern part of country). At the same time the impact of climate change will determine the spatial and temporal dynamics of pests and pathogenic species. The phenomenon of climate aridization was expressed also through the impact of the Microsphaera alphitoides disease, intensity of “mildew” attack being based on the climatic conditions of the study region. Obtained data, for confirmation, were correlated with indications of bioindicators, present in the study region.

Background and aims COVID-19 pandemic has caused significant disruption in training which is even more pronounced in the surgical specialties. We aim to assess the impact of COVID-19 pandemic on core surgical training. Methods All core surgical and improving surgical trainees in West of Scotland region were invited to participate in an online voluntary anonymous survey via SurveyMonkey. Results 28 of 44 (63.6%) trainees responded, 15 (53.6%) were CT1/ST1. 14 (50.0%) working in teaching hospital and 15 (53.6%) working in general surgery. 20 (71.4%) felt that due to the pandemic they have less opportunity to operate as the primary surgeon. 21 (75.0%) have not attended any outpatient clinics. 8 (28.6%) did not have any form of access to the laparoscopic box-trainer. 20 (71.4%) felt their level of confidence in preforming surgical skills has been negatively impacted. 18 (64.3%) found it difficult to demonstrate progress in portfolio. 21 (75.0%) trainees have not attended any teaching. 10 (35.7%) trainees have been off-sick. 8 (28.6%) trainees have felt slightly or significantly more stressed. Conclusion COVID-19 pandemic has an unprecedented negative impact on all aspects of core surgical training. The long term impact on the current cohort of trainees is yet to be seen.

Purpose Child neglect is the most common form of maltreatment but is also one of the most complex. Neglect has a long-term negative impact on children and young people’s development and wellbeing. This study examined 20 recent serious case reviews that had taken place in England where neglect was a feature. The purpose of this study is sought to explore the barriers, which exist for social workers in England in identifying and responding to neglect in a timely, appropriate and effective manner. Design/methodology/approach Thematic analysis identified four main themes that were likely to impact upon effective interventions. Findings Challenges in terms of the definition of neglect and how to identify it; the use of neglect toolkits; the impact of organisational cultures on practice and the voice of the child. Originality/value In spite of its prevalence there is a dearth of literature relating specifically to the issue of neglect. There is a need for further research to be undertaken because of the acknowledged, seriousness and potential longstanding negative impact on children even into adulthood (Horwath, 2013). It is hoped that this study provides a useful insight into some of the barriers that exist for social workers in working effectively with children and families for whom neglect is an issue.

Neurodegenerative diseases are progressive diseases of the nervous system that lead to neuron loss or functional disorders. Neurodegenerative diseases require long-term, sometimes life-long pharmacological treatment, which increases the risk of adverse effects and a negative impact of pharmaceuticals on the patients’ general condition. One of the main problems related to the treatment of this type of condition is the limited ability to deliver drugs to the brain due to their poor solubility, low bioavailability, and the effects of the blood-brain barrier. Given the above, one of the main objectives of contemporary scientific research focuses on the prevention of neurodegenerative diseases. As disorders related to the competence of the antioxidative system are a marker in all diseases of this type, the primary prophylactics should entail the use of exogenous antioxidants, particularly ones that can be used over extended periods, regardless of the patient’s age, and that are easily available, e.g., as part of a diet or as diet supplements. The paper analyzes the significance of the oxidoreductive balance in the pathogenesis of neurodegenerative diseases. Based on information published globally in the last 10 years, an analysis is also provided with regard to the impact of exogenous antioxidants on brain functions with respect to the prevention of this type of diseases.

302 Background: The preoperative stage and intraoperative stage of gastric cancer were unified as the clinical stage in the 8th edition of the TNM classification (UICC). Although there are some reports about the relationship between preoperative stage and prognosis, the relationship between intraoperative stage and prognosis remains unclear. The aim of this study was to clarify the impact of intraoperative diagnosis and staging on long-term survival. Methods: Overall survivals were examined in 915 patients who underwent curative resection for gastric adenocarcinoma between April 2011 and March 2019 in our hospital. Results: The median age of the patients was 69 years (27-90 years), including 585 male and 330 female. The median follow-up period was 33.6 months (0.1-86.7 months). The number of the patients according to intraoperative stage were 641(70.1 %) in stageI, 15(1.6%) in stageIIA, 135(14.8%) in stageIIB, 111(12.1%) in stageIII, 12(1.3%) in stageIVA and 1(0.1%) in stageIVB. The hazard ratios of intraoperative stage for overall survival were as follows (ref: StageI); StageIIA, 6.990 (95% CI: 2.473-19.760, p < 0.001), StageIIB, 2.234 (95% CI: 1.220-4.092, p = 0.009), StageIII, 4.091 (95% CI: 2.416-6.928, p < 0.001), StageIVA, 6.061 (95% CI: 2.150-17.080, p < 0.001), StageIVB, 14.92 (95% CI: 2.035-109.3, p = 0.008). Conclusions: The survival of intraoperative StageIIA was poorer than StageIIB/III. Intraoperative positive lymph node metastasis could be negative impact of survival, even if tumor invasion was T1 or T2.
