景觀樹木外科手術的工法和成效
Authors: 籃世旭 籃世旭 , 盧惠敏 盧惠敏
Published: June 2024

樹木對居住在城市的人類生活影響巨大，不僅能美化環境、過濾空氣和水、更能激發正向情緒，展現各城市於文化、歷史、地理、生態等特色。因此城市中樹木的健康和風險問題更應被關注，以避免樹木感染災害及無預警倒伏或枝條斷落等公共安全問題。
本研究目的主要是進行藉由「景觀樹木VTA健康檢查診斷評估表」探討經由「改良式樹木外科手術」的腐朽處理，包括傷口腐朽清創去除、高溫碳化保護及塗佈傷口保護藥劑處理的9個案例的分析，探討其是否能有效的抑止腐朽菌和促進樹木生長勢的恢復。
研究結果顯示，使用｢景觀樹木VTA健康檢查診斷評估表」，評估改良式樹木外科手術前和後的樹木的生長狀況，是可行但有其限制，術後若達五年以上的生長恢復期，則VTA評估表的分數和樹木健康程度才會有呈現出顯著關係。若恢復期不及五年，則需再配合觀察腐朽傷口癒傷組織的形成、傷口面積的減少、無流出組織液等來判定「改良式樹木外科手術｣對樹木生長幫助。
樹木外科手術的成效，在國內外的各方專家學者有許多不同的看法，這些歧異或許是因為植物種類不同、環境風土差異、動植物生態差異、各家所使用處理方法不同。後續研究可以針對這些歧異度如何影響外科手術的成效來進行探討。Trees have a huge impact on human being living in cities. They can not only beautify the environment, filter air and water, but also stimulate positive emotions and represent the cultural, historical, geographical, ecological, and other characteristics of each city. Therefore, more attentions should be paid to the health and risk issues of trees in cities to avoid tree infection disasters and public safety issues such as unexpected tree falling without warning or branch breakage.
The purpose of this study is mainly to explore the decay treatment through ''modified tree surgery'' through the ''Landscape Tree VTA (Visual Tree Assessment) Form'', including wound decay debridement and removal, high-temperature carbonization protection, and wound protection agent application. An analysis of 9 cases was conducted to explore whether it can effectively inhibit decay bacteria and promote the recovery of tree growth.
The research results show that using the '' Landscape Tree VTA Form '' to evaluate the growth status of trees before and after modified tree surgery is feasible but has its limitations. If there is a growth recovery period of more than five years after surgery, then there will be a significant relationship between the score of the VTA and the health of the tree. If the recovery period is less than five years, it is necessary to observe the formation of callus tissue from the decayed wound, the reduction of the wound area, and the absence of tissue fluid leakage to determine whether the ''modified tree surgery'' will help the tree growth.
Experts and scholars worldwide have many different opinions on the effectiveness of tree surgery. These differences may be due to different plant species, different environmental conditions, different animal and plant ecology, and different treatment methods used by each company. Follow-up research could explore how these differences affect surgical outcomes.

面對全球增溫挑戰，都市高溫化造成的影響不可忽視，高溫衝擊不只影響民眾健康、生活品質，還可能增加民眾的能源負擔，加劇社會階層差異的惡性循環；為了將未來的升溫情境維持在攝氏1.5度之內，臺灣響應淨零排放國際趨勢，規劃「2050淨零排放路徑」，期能大幅度削減溫室氣體排放，其中高溫調適與淨零排放目標中的「淨零綠生活」以及「公正轉型」兩項關鍵戰略息息相關，以臺北都會密集區為例，整合都市高溫相關圖資以及資料，呈現都市地理環境、高溫分布、建築結構、風場環域、熱舒適等項的分布，了解高溫脆弱度較高區域的蓄熱因素，針對都市高溫下的都市規劃及建築規範，探討如何藉由落實高溫調適策略，推廣節能知識以及建築營運碳排放減量等。結合能源使用資料與公正轉型原則，探討推動淨零轉型過程，透過都市降溫，增進共有共享的戶外空間熱舒適，維護大眾前往戶外的意願以及平等權利。高溫調適可視為推動淨零排放的重要指標之一，新加坡為都市降溫已制訂出具體的管制門檻，並透過政策鼓勵、立法管制、擴大預算編列加速推動，現臺灣已有明確的淨零轉型之路，期能儘早建置具體的都市高溫因應策略法規。

 

To maintain future temperature rise within 1.5 degrees, Taiwan has followed the international net-zero emissions trend and planned a "2050 Net-Zero Emissions Path", which is expected to significantly reduce greenhouse gas emissions. Facing the increasingly severe urban high temperature problem, high temperature adjustment is closely related to the two key strategies of "Net Zero Green Living" and "Just Transition" in the 2050 Net-Zero Emissions Path goals. Taking the Taipei metropolitan area as an example, this article integrates urban high temperature-related graphics and data to present urban high temperature distribution, building structure, wind field environment, thermal comfort, etc., aiming at urban planning and building regulations under urban high temperature, and discusses how to promote energy-saving knowledge and reduce carbon emissions in building operations by implementing high-temperature adaptation strategies. Urban heat mitigation can be seen as closely related to net-zero emissions. Taiwan now has a clear path to net-zero transition and it is strongly suggested to form solid urban high temperature response strategies and regulations.

Authors: De Nardi Laura , Insalaco Antonella , De Benedetti Fabrizio
Published: June 2024

Fever is a very common symptom in children, mostly due to infections. It is a physiological body defence mechanism against damage. However, when it is recurring, it is difficult to understand which are the underlying causes. Recurrent fever is most commonly due to trivial infections of the 1st infancy. However, it can seldom be the expression of inborn errors of immunity, monogenic periodic fevers, neoplasm, or other rheumatologic conditions. What comes with the fever (i.e. specific accompanying signs and symptoms) is essential to distinguish between such different diseases. This paper aims to provide an overview on the causes of recurrent fever in paediatrics, providing a practical guide to assist the paediatrician who needs to disentangle between different diagnoses.

Published: June 2024

Social withdrawal has recently been recognized by the Istituto Superiore di Sanità (the Italian National Institute of Health) as one of the most common problems among adolescents in the post pandemic world, with an onset estimated between 11 and 13 years of age. Both the paediatrician’s office and the school are a primary observation point for the early identification of the problem. This article describes the possible manifestations of social withdrawal in adolescence, underlying risk factors and comorbidities (i.e. psychological vulnerability, difficulties in the relationship within and outside the family, internet addiction, anxious somatizations and neurodivergent condition), focusing on the role that the paediatrician can play in the early detection of risk factors and on the importance of a careful and informed approach to youth at risk. For the paediatrician, it is essential to establish a collaborative relationship with the parents and to be aware of the resources locally available to address the problem.

Plato’s Parasite: Re:turning with(in) Deleuze
Authors: Robaard Meike
Published: June 2024

Upon encountering Deleuze’s Nietzschean reiteration that it is the task of modern philosophy to overturn Platonism, as put forth in Difference and Repetition (1968), this article worms its way in, seeking to unearth not merely what Deleuze’s differential repetition signifies, but also what such gestures generate in (re)turn. By considering Deleuze’s intervention as a manifold performance of (re)purposeful gestures that put the notion of reversal itself into question, and after providing a brief, Deleuzian, exposition of Platonism, this article not only homes in on Deleuze’s demiurgic detection of an overturning gesture paradoxically already present in, if not itself initiated by, Plato’s writing, but additionally calls attention to other curiosities turn up when reading besides, instead of against, the grain. In introducing Michel Serres as a critical companion, this experimental article ultimately ponders over and entertains the productive possibility of framing Plato’s poignant predicament as a (problem of the) parasite. Composed as fruitful conceptual personae, parasites emerge throughout this article in unforeseen manners, time and time again bringing new food for thought to the table.
Afrophobia and Belongingness: Why Ubuntu Fails and Conversationalism Works
Authors: Attoe Aribiah David
Published: June 2024

For a long time, some African thinkers have sought to project communalism—or, more specifically, ubuntu—as the face of social life in African thought. Unfortunately, rather than emphasizing ubuntu, the reality of things in Africa portrays contextualization and exclusion in some of its most destructive form. One of the more prominent examples of this is the Afrophobic sentiments that have pervaded and continue to pervade the continent. Often, ubuntu is touted as the solution to these types of problems since it emphasizes belongingness and a certain camaraderie that involves mutual caring and sharing. However, this article proposes conversationalism as an alternative to ubuntu, which is too bordered, in one sense, or too utopic, in another. It begins by properly mapping out a general overview of the sociopolitical and existential context in which most Africans live today. It then shows how the current iteration of ubuntu fails. Finally, borrowing from conversationalism, it proposes arumaristics (or creative struggle) as the more viable solution to the problem of Afrophobia and other related forms of exclusion.
Causal Associations of Environmental Pollution and Cardiovascular Disease: A Two-Sample Mendelian Randomization Study
Authors: Gao Hui , Li Jiahai , Ma Qiaoli , Zhang Qinghui , Li Man , Hu Xiaoliang
Published: June 2024

Background: There is growing evidence that concentrations of environmental pollutants are previously associated with cardiovascular disease; however, it is unclear whether this association reflects a causal relationship.
Methods: We utilized a two-sample Mendelian randomization (MR) approach to investigate how environmental pollution affects the likelihood of developing cardiovascular disease. We primarily employed the inverse variance weighted (IVW) method. Additionally, to ensure the robustness of our findings, we conducted several sensitivity analyses using alternative methodologies. These included maximum likelihood, MR-Egger regression, weighted median method and weighted model methods.
Results: Inverse variance weighted estimates suggested that an SD increase in PM2.5 exposure increased the risk of heart failure (OR = 1.40, 95% CI 1.02–1.93, p = 0.0386). We found that an SD increase in PM10 exposure increased the risk of hypertension (OR = 1.45, 95% CI 1.02–2.05, p = 0.03598) and atrial fibrillation (OR = 1.41, 95% CI 1.03–1.94, p = 0.03461). Exposure to chemical or other fumes in a workplace was found to increase the risk of hypertension (OR = 3.08, 95% CI 1.40–6.78, p = 0.005218), coronary artery disease (OR = 1.81, 95% CI 1.00–3.26, p = 0.04861), coronary heart disease (OR = 3.15, 95% CI 1.21–8.16, p = 0.0183) and myocardial infarction (OR = 3.03, 95% CI 1.13–8.17, p = 0.02802).
Conclusion: This study reveals the causal relationship between air pollutants and cardiovascular diseases, providing new insights into the protection of cardiovascular diseases.

Firstly, the ResNet network model is built, which contains two residual units and three fully connected layers. Secondly, the pruning method of network slimming is introduced to compress the neural network model without affecting the recognition accuracy. Finally, the model was trained using modulated signal samples for the RaidoML2016.10a international standard dataset. The experimental results show that the recognition accuracy of the pruning ResNet modulation recognition algorithm can reach 95% under the condition of 12dB signal-to-noise ratio, and the number of model parameters is only 5.7×104.
Numerical Study on the Relationship between Lift-to-drag Ratio and Airfoil of Gliders in High-speed Cruising Conditions
Authors: Luo Siqi
Published: June 2024

This research attempts to examine the aerodynamic characteristics of gliders, specifically concentrating on the impact of airfoil configurations and wing designs on the lift-to-drag ratio when operating at high velocities. Amid rising concerns for environmental sustainability and the pursuit of greater aviation efficiency, traditional approaches, including the enhancement of lightweight materials and the adoption of biofuels, encounter limitations. Particularly in extending the range and improving the efficiency of gliders, the advancements in material weight reduction and biofuel efficacy are approaching their limits. This challenges the industry to seek innovative solutions beyond these conventional methods to achieve significant gains in aircraft performance and environmental impact reduction. To tackle such obstacles comprehensively, this study employs a combination of experimental and computational fluid dynamics (CFD) approaches to analyze these crucial aerodynamic variables. This study illustrates that optimizing aspect ratios and airfoil shapes, particularly through the utilization of high aspect ratio cambered airfoils like the NACA 4412, can substantially improve glider performance. By minimizing induced drag and enhancing lift, these design modifications significantly elevate the overall lift-to-drag ratio, offering a pathway to more efficient and environmentally friendly aviation technologies. These developments not only provide a focused remedy for the identified deficiencies but also indicate progress in integrating aircraft design with initiatives for environmental sustainability. This research highlights its potential impact on the broader endeavor to achieve sustainable aviation by offering practical strategies for the development of more efficient and environmentally friendly aircraft, thereby making a substantial contribution to aerospace engineering and environmental science.

Authors: Zheng Yang
Published: June 2024

Multi-beam bathymetry system is an advanced technology to measure the seabed based on single-beam bathymetry. In this paper, the greedy algorithm and variable step traversal method will be used to establish the mathematical models of coverage width and overlapping rate of adjacent strips of multi-beam sounding, and the best scheme of survey line layout will be designed by establishing the optimization model. According to the established mathematical model of overlap rate, the mathematical model of coverage width of multi-beam sounding in three-dimensional rectangular waters is optimized. Finally, according to the real life, with the overlapping rate of adjacent strips within 10% to 20% as the limiting condition and the minimum total length of survey lines as the objective function, a single-objective optimization model is established. Then, Python is used to solve the problem through greedy algorithm and variable step-size traversal algorithm, and it is found that the included angle of survey line direction in the optimal scheme is 90, and the minimum total length of survey line is 68 nautical miles. Stability analysis is carried out by changing the constraint range of overlap rate.

How Far Do Patents Obtained Through Mergers and Acquisitions Create Innovative Capabilities? -- A Case Study of Evergrande Electric Vehicle Company
Authors: Stahlecker Sissi
Published: June 2024

The quantity of a company’s patents has long been seen as a reliable indicator of its innovative capability, which to a large extent determines its success in the market. Firms often (through direct merger and acquisitions) purchase patents from other firms in the hope of achieving greater innovation. However, the experience of China’s electric vehicle firm Evergrande Electric Vehicle Company may provide us more insights into the dynamics between number of patents and innovation. Through a thorough analysis of why Evergrande EV failed to transform purchased patents into innovative capacities, this article proposes that the Absorptive Capacity, defined by Cohen and Levinthal (1989, 1990) as a firm’s ability to value, assimilate, and utilize new external knowledge, is a more accurate gauge of a firm’s innovativeness than merely the number of purchased patents. The case study of Evergrande EV also echoes previous studies that prior knowledge in a given filed is crucial to a firm’s ability to absorb and profitably exploit purchased patents. In addition, a strong technological leadership team is also important, according to exclusive interview of a former Vice President of Evergrande EV.
