Diagnosis, management, and treatment of a heritage-built environment in South Chile
No full textIn Chile, photography arrived at the end of the 19th century together with the establishment of settlements of migrants from central Europe to southern Chile. The aims of this study are: (i) contextualise functional states of existing buildings in a specific sector of the historic Valdivia city centre; (ii) determine the state of conservation of the 42 cases under study; (iii) conduct qualitative and quantitative analyses of the main pathologies presented in the sample; (iv) perform an analysis focused on the urban context according to façade alignment, façade visibility index, and ratio of height versus street width; and (v) comparatively analyse the results achieved. This research reflects the importance of developing innovative procedures and mitigation strategies focused on preventive maintenance actions and future control systems that can maximise the resilience of a specific local context (Los Ríos region) and its surroundings. This study revealed that the number of pathologies detected was directly proportional to the state of conservation of the cases, classified by the functional service life model. Properties in Condition C were mainly affected by pathologies of a structural nature, which indicates that their functionality is not guaranteed, and a deeper inspection is needed for conservation and preservation actions.

Sub-activity analysis by using wristband-type wearable health devices to measure construction workers’ physical demands
No full textUnderstanding and managing the physical demands of construction workers is critical to their safety, health, and productivity. Construction tasks, especially cyclic and non-cyclic activities are highly variable. Cyclic tasks involve repetitive actions, which if not well-distributed, can lead to cumulative fatigue and long-term health issues. Conversely, non-cyclic tasks are unpredictable and irregular, making it challenging to allocate workloads effectively. Despite these challenges, few studies have investigated continuous physical demands for both task types, particularly in dynamic, onsite construction environments. Filling this gap is essential for developing practical strategies to improve workload allocation, mitigate health risks, and optimize workforce management. This study addresses this critical gap by using lightweight wearable wristbands equipped with heart rate (HR) biosensors to monitor workers’ activities without disrupting their tasks. The percentage of heart rate reserve (%HRR) is calculated to quantify the continuous physical demands of 10 construction workers performing both cyclic and non-cyclic tasks across two construction sites over three weeks. Results revealed significant workload variations between task types and work patterns. For instance, stationary tasks (‘work without moving’) strongly influenced %HRR for rebar workers, while dynamic tasks (‘work with moving’) had a greater impact on form workers. Additionally, while some daily average %HRR values fell below the 33% threshold, extended high-intensity periods (exceeding 40% HRR for over 30 minutes) posed potential health and safety risks for construction workers. This research demonstrates the potential of long-term HR monitoring to address workload disparities, ensure balanced task allocation, and reduce health risks for construction workers
A SDGs-oriented evaluation of the ecological sustainability of international horticultural exposition sites in Chengdu, China
No full textThis study employs the AHP-entropy weight methodology and a spatial econometric regression model to evaluate the ecological sustainability and its changes between the current situation and the planning scenario at the 2024 Chengdu International Horticultural Exposition in China. The results indicate a notable shift: a reduction in areas of low and highest sustainability and significant expansion in medium levels, which spans 34.04 hm2. The transformation of village settlements, wastelands, and farmland into exhibition gardens and water bodies is shown to bolster medium-level ecological sustainability by enhancing rain and flood security and mitigating the risk of flood disasters. The development of Integrated Service areas will lead to an increase in impervious surfaces. The anticipated forest loss, along with declines in vegetation coverage, three-dimensional green volume, and vegetation carbon stock will adversely affect the highest sustainability. The study identifies a robust correlation between ecological sustainability level and quantitative indicators, with regression coefficients ranging from 0.5875 to 0.7148. This analysis provides policymakers with valuable insights and directions for the sustainable planning and development of mega-events
Recognition and optimization of landscape genes in traditional settlements: a case of Meishan area
No full textTraditional settlement landscapes provide vital ecosystem services and represent significant cultural heritage, making their preservation crucial for national cultural development and rural revitalization. This study focuses on Meicheng Town in the Meishan area, utilizing landscape gene theory to classify and identify cultural landscape features. By integrating the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE), the study develops a landscape gene sorting index system, systematically evaluating 16 sub-categories of landscape factors. The results highlight topography and building decoration as dominant features that should be prioritized for preservation. However, areas such as building materials, traditional culture, and folk customs require significant improvement. Additionally, the river and road landscapes present opportunities for enhancement to strengthen the town’s cultural identity and aesthetic quality. The study provides practical recommendations for optimizing Meicheng Town’s landscape, balancing the preservation of traditional elements with modern development needs. This approach addresses gaps in the literature on settlement landscape genes and offers strategies for sustainable rural cultural landscape development
Spatial-temporal evolution of land ecological health and influencing factors in China\u27s ecological civilization pilot area
No full textIt is crucial to assess the land ecosystem health (LEH) in China’s national pilot zones (NPZ) for ecological conservation and identify the primary factors that impact it. This is crucial for developing China’s ecological civilization and fostering sustainable, eco-friendly economic development. The study utilizes the pressure-state-response (PSR) and environment-economy-society (EES) model, relying on the panel data of 11 cities of Jiangxi in the NPZ for ecological conservation from 2005 to 2020, measuring the LEH in the national ecological civilization pilot zone using the comprehensive index evaluation method. The main contribution of this study is to optimize the land ecological health index system, construct an improved PSR-NES theoretical model that is more suitable for NPZ, reveal the spatial and temporal evolution characteristics of LEH in NPZ from the city scale, and refine the key driving factors. Results show that (1) The LEH exhibited a general shift from a state of “less healthy” level to the “healthier” level; (2) Differences in LEH evolution in different cities. The overall trend of “north to south and east to west” is gradually improving. (3) Urbanization has a strong role in the promotion of LEH, and economic development shows a significant dampening effect

Tobulesnės technologinės aplinkos kūrimas pramonės įmonėse
Santrauka
Sparčiai kintančiame pasaulyje pramonės įmonės turi vis mažiau laiko naujoms idėjoms generuoti, pristatyti ir įgyvendinti. Norint neatsilikti nuo konkurentų, būtina nuolat stebėti išorinę ir vidinę įmonių technologinę bei organizacinę aplinką, nuolat tobulinti procesus ir tinkamai parengti darbuotojus naujovėms. Įmonėms augant ir gaunant didesnį pelną, aukščiausio lygio vadovai neretai ima po truputį tolti nuo procesų valdymo technologinės bazės problemų sprendimo ir veiklos tobulinimo, o toks požiūris veda į įmonės stagnaciją. Siekiant to išvengti ir užtikrinti efektyvų problemų sprendimą bei įmonės vystymąsi, reikia sukurti pramonės įmonių vidinės aplinkos gerinimo modelį. Straipsnyje nagrinėjamas pažangesnės technologinės aplinkos kūrimas Lietuvos pramonės įmonėse, aptariami aplinkos gerinimą lemiantys veiksniai ir tobulinimo būdai, pateikiamas technologinės aplinkos apibrėžimas, darbuotojų reakcija į pokyčius organizacijoje, pristatoma technologinės ir administracinės aplinkos tobulinimo metodika, tyrimo rezultatai bei supaprastintas įmonės aplinkos tobulinimo modelis.

The relationship between earnings management and audit opinion
No full textThis study is conducted to investigate the relationship between earnings management (EM), audit quality (AQ) and qualified opinion of financial statements (AO) of listed firms on Vietnam Stock Exchange. Data were collected from 499 listed firms from 2018 to 2020 with 1,497 observations, of which 101 are observed with qualified opinions. Regressions of Logit and GLS are employed. The results reveal that earnings management has a positive relationship with qualified opinion, while audit quality has a negative association with qualified opinion and earnings management. In this research, we consider the interaction of audit quality with earnings management and qualified opinion. An interesting finding is that the impact of audit quality is weaker than that of earnings management and qualified opinion, so the interaction variable has a positive relationship with both qualified opinion and earnings management. Based on the findings, several suggestions are proposed for users of financial statements and auditors as well to assess the appropriateness of the opinion that is not an unqualified opinion
