The Role of Watershed Management Board in the Rehabilitation of Butuanon River Watershed in Cebu, Philippines

This study was conducted to assess the role of Butuanon River Watershed Management Board (BRWMB) in rehabilitating the Butuanon River in Cebu, Philippines. Data was gathered through key informant interviews with officials of the Board and a self-administered questionnaire for the members of the Board and was analyzed through descriptive and thematic analyses. Results showed that since the creation of the Butuanon River Watershed Water Quality Management Area (BRW WQMA) in 2014, the river's biological oxygen demand (BOD) level has decreased. While the level has yet to meet the water quality guidelines of DENR's Class D rivers, the Board's initiatives like clean-up activities, information, education, and communication (IEC), and the relocation of informal settlers residing at riverbanks contributed to the improvement of the river's water quality. The activities conducted by the Board strengthened the linkages with other stakeholders. The good working relationship among the stakeholders facilitated the convergence of their resources, making their efforts to rehabilitate the Butuanon River more coordinated and sustainable. Furthermore, Mandaue LGU, the chair of BRWMB, integrated its efforts in its Comprehensive Land Use Plan (CLUP) and the 10-year Action Plan of the BRW WQMA in its Butuanon River Rehabilitation Plan. Results revealed that the existence of BRWMB played a vital role in the Butuanon River's rehabilitation, and such efforts are hoped to be sustained with the participation of the various stakeholders and formulation of policies to support all efforts of the Board.

Quality and Risk Management in Data Mining: A CRISP-DM Perspective.

The area of data science knowledge responsible for dealing with this new reality is diffuse, including mathematics, statistics, computing, engineering, psychology, and administration, among many other areas that make up a new scenario that is still changing. Different models have emerged over the years to systematize the procedures to be followed. Among them, CRISP-DM (Cross Industry Standard Process for Data Mining) has become one of the most widespread in the industry. However, the lack of detailed instructions means the framework is often incorrectly used. Therefore, this research aims to present a utilitarian and didactic model based on the latest advances in the literature and through the lens of production engineering. In order to achieve this objective, exploratory research was carried out based on a systematic review and subsequent categorization of each of the CRISP-DM steps, detailing the authors’ contributions to each stage. In addition, it is proposed that guidelines from the areas of Quality Management and Risk Management be added to the subject, consolidating a useful and didactic model of relevance.

MATHEMATICAL MODELLING OF THE PROCESS OF QUALITY CONTROL OF CONSTRUCTION PRODUCTS

The study's abstract summarizes the findings of years of research in the area of quality management of industrial production and construction production, which were based on mathematical modeling techniques, process, and outcomes of implementing the developed program of monitoring and quality control in the enterprise's production process. The objective of this work is to show to the scientific community the useful outcomes of mathematical modeling in software applications. Quality control and safety represent increasingly important concerns for project managers. Defects or failures in constructed facilities can result in very large costs. Even with minor defects, re-construction may be required and facility operations impaired. Increased costs and delays are the result. In the worst case, failures may cause personal injuries or fatalities. Accidents during the construction process can similarly result in personal injuries and large costs. Indirect costs of insurance, inspection and regulation are increasing rapidly due to these increased direct costs. Good project managers try to ensure that the job is done right the first time and that no major accidents occur on the project. The research focused on describing applicable mathematical models, viewpoints, and practical outcomes of their use in the applied sector to evaluate quality control. This mathematical model was applied by the authors. The outcomes of using this approach are presented in the article. By utilizing mathematical modeling techniques, the authors created an experimental software management and quality assessment system. The authors continue their study in this area to enhance prognostic and diagnostic processes based on mathematical modeling methodologies for diagnostic systems and quality management systems.. The independent quality control, which was based on some traditional inspection techniques and used mathematical modeling techniques, revealed a negligible partial discrepancy in the results of the estimation, proving both the efficacy of the product and the suitability of the mathematical modeling concept. Keywords: Quality control, mathematical modeling, construction quality.

Simulation of outdoor air pollution in Southampton

The city of Southampton is committed to monitoring and reducing outdoor air pollution, in particular, Nitrogen Dioxide (NO2) and Particulate Matters (PM2.5/PM10), which have been linked with adverse health effects under short- or long-term exposure. This project investigates the air pollution contributed mainly by road sources, which consist of major and minor roads in Southampton, by using Atmospheric Dispersion Modelling Software (ADMSRoads), and provides further understanding on the air pollution contributions based on qualitative and quantitative analysis. The model was validated by comparing the modelled concentration with the observed data from the Southampton AURN pollution monitoring station. This study has found out that although the simulation exhibits a tendency to underpredict pollution concentrations, the dynamics of the model were relatively promising as it managed to capture the trends over time of the concentration of air pollutants relatively consistently. Therefore, future improvements to the model may be made by applying correction factors to overcome the bias offset to obtain more realistic predictions of air quality. The simulation has also correctly predicted poorer air quality within the Air Quality Management Areas (AQMA) declared by Southampton City Council (SCC), which implies that road sources have a notable contribution towards the air pollution. The advantages of this model are that it can be quickly altered to predict response to future policy actions and that it has sufficient resolution to be used for epidemiological studies linking air pollution with the prevalence of health conditions in the city. The findings so far indicate that further pollution control measures are still warranted as most of the pollutant concentrations from road sources exceed the latest (2021) WHO air quality guidelines developed to protect public health from effects of exposure to air pollutants.

Competence-based catalog of learning objectives for the subject area of quality management in medical studies - position paper of the working group Quality Management in Education, Training and Continuing Education of the Society for Quality Management in Health Care (GQMG).

Traditionally, direct medical competences are taught in medical studies, whereas leadership and quality management competences are hardly taught, although graduates are already confronted with management tasks at the beginning of their clinical work. With the upcoming amendment of the Medical Licensing Regulations, this topic area will probably be addressed and must be adequately taught by the faculties. The learning objectives in the area of quality management listed in the current working version of the German National Catalogue of Learning Objectives in Medicine (NKLM) 2.0 have so far been formulated in rather general terms and need to be concretized. To develop a competence-based learning objectives catalog for the topic area of quality management in medical studies as a structured framework recommendation for the design of faculty teaching-learning programs and as a suggestion for further development of the NKLM. The competence-based learning objectives catalog was developed by an eight-member working group "Quality Management in Education, Training and Continuing Education" of the Gesellschaft für Qualitätsmanagement in der Gesundheitsversorgung e.V. (GQMG) within the framework of a critical synthesis of central publications. The members of the project group have many years of project experience in quality management in health care as well as in university didactics. Six basic competence goals as well as 10 specific competence goals could be formulated and consented upon. These are each flanked by a list of essential basic concepts and examples. These focus on quality improvements, including patient safety and treatment success against the background of a physician leadership role in an interprofessional context. A competency-based set of learning objectives has been compiled that encompasses the necessary concepts and basic knowledge of quality management required for those entering the profession to understand and actively participate in quality management after completing medical school. To the authors' knowledge, no comparable learning objectives catalog is currently available for medical studies, even internationally.

Emerging research trends of total quality management in the COVID-19 pandemic: a dynamic evolution analysis

As the COVID-19 pandemic rages, the changing trends and emerging areas of total quality management (TQM) research before and after the COVID-19 pandemic are spotlighted, while the links between TQM and environmental social governance (ESG) are deeply discussed in this study. To explore the impact of the pandemic on TQM research, a comprehensive bibliometric analysis is conducted by collecting 1465 pre-pandemic and 76 post-pandemic publications from the WoS database. Further, the fundamental characteristics, conceptual structure and intellectual and social structure of TQM research are statistically analysed through bibliometric tools. Consequently, this article methodically sorts out the evolution, new research areas, primary sources, national collaboration networks and influential themes within an intricate and large TQM research system. The linkages between ESG and TQM are explored by focussing on some emerging topics after the outbreak such as sustainability and environmental management, which advances the innovative attempt towards the goal of cooperating sustainability. Finally, we offer some enlightening new perspectives on economic construction and social life during the pandemic to better cope with the negative effects of the pandemic.

Developing effective strategic decision-making in the areas of hotel quality management and customer satisfaction from online ratings

ABSTRACT The current paper uses MUSA, an MCDA method, to investigate the contribution (perceived importance) of four core aspects that capture guests’ experience – i.e. location, cleanliness, service and value – to overall guest satisfaction, indicate, through importance–performance analysis, the weak and strong points of customer satisfaction, explore guests’ demanding level and prioritize the service areas where improvement actions will be more effective. To do so, 150,639 attribute and overall satisfaction ratings were retrieved for hotels in four Ionian Sea islands on TripAdvisor. The examined criteria were found to contribute differently to overall guest satisfaction across the destinations. Also, service revealed as the weak point of customer experience for hotels in Corfu and Zakynthos, whilst location and cleanliness for hotels in Cephalonia and Lefkada. The results further suggest that Ionian Sea islands’ hotel customers are non-demanding and that quality improvement investments/actions in value and service would be more effective in delighting customers.

Effect of positive psychological capital on service quality management in higher education

The objective of this paper is to extend the boundaries of positive psychological capital to the area of service quality management in higher education. This research addresses the relationship of each of the positive psychological capital (PsyCap) resources of hope, self-efficacy, resilience and optimism and PsyCap as a higher order construct with service quality management. This study proposed a model in which positive psychological capital (PsyCap) affects the perceptions of service quality in the higher educational sector. Structural equation modelling was used to test the hypothesised relationships on a sample of 1,082 students in an Arab regional university - Egypt branch. The findings support a positive relationship between: a) each of the resources of PsyCap, and with each of the dimensions of service quality management; b) PsyCap, as a higher-order multidimensional construct, with each dimension of service quality management and with service quality management.

Impact of local air quality management policies on emergency hospitalisations for respiratory conditions in the North West Coast region of England: a longitudinal controlled ecological study

BackgroundAir quality is monitored at a local level in the UK as part of the Local Air Quality Management (LAQM) system. If air quality objectives within an area are not achieved an Air Quality Management Area (AQMA) is declared and action plan developed. The efficacy of this system in reducing air pollution has increasingly come into question, however very little is known about its impact on health or health inequalities. We therefore investigated the effect of declaring an AQMA on emergency hospitalisations for respiratory conditions in the North West Coast region of England, and examined whether the effect differed between more compared to less deprived neighbourhoods.MethodsThis longitudinal controlled ecological study analysed neighbourhoods located within or touching the boundaries of AQMAs declared in the North West Coast region between 2006 and 2016. Each of these intervention neighbourhoods were matched with five control neighbourhoods which had never been located within/touching an AQMA boundary. Difference-in-differences methods were used to compare the change in hospitalisation rates in the intervention neighbourhoods to the change in hospitalisation rates in the matched control neighbourhoods, before and after the declaration of an AQMA.ResultsIn total, 108 intervention neighbourhoods and 540 control neighbourhoods were analysed over the period 2005–2017, giving a total sample size of 8424 neighbourhood-years. Emergency hospitalisations for respiratory conditions decreased in the intervention neighbourhoods by 158 per 100,000 per year [95% CI 90 to 227] after an AQMA was declared relative to the control neighbourhoods. There was a larger decrease in hospitalisation rates following the declaration of an AQMA in more compared to less income deprived neighbourhoods.ConclusionsOur results suggest the LAQM system has contributed to a reduction in emergency hospitalisations for respiratory conditions, and may represent an effective strategy to reduce inequalities in health. These findings highlight the importance of measuring the success of air quality policies not just in terms of air pollution but also in terms of population health.

An Assessment of the On-Road Mobile Sources Contribution to Particulate Matter Air Pollution by AERMOD Dispersion Model

On-road mobile sources of emissions make important contributions to particulate matter pollution (PM2.5–PM10) in cities. The quantification of such pollution is, however, highly challenging due to the number of interacting factors that affect emissions such as vehicle category, emission standard, vehicle speed and weather conditions. The proper identification of individual sources of emission is particularly necessary for air quality management areas. In this study, we estimated exhaust and non-exhaust traffic-related PM2.5 and PM10 contributions to total ambient pollution in Banská Bystrica (Slovak republic) by simulation based on the AERMOD dispersion model. Emission rates of particular vehicle categories were obtained through vehicle population statistics, traffic data survey and emission factors from the EMEP/EEA air pollutant emission inventory guidebook. Continuous PM10 and PM2.5 data from air quality monitoring stations were analysed for the years 2019–2020 and compared with modelled concentrations. The annual concentration values of PM2.5 and PM10 in the study area reached 16.71 μg/m3 and 15.57 μg/m3, respectively. We found that modelled PM2.5 peak concentration values exceeded the WHO air quality guideline annual mean limit. Traffic-related PM2.5 and PM10 contributions to ambient pollution at the reference point located nearby to a busy traffic route were approximately 25% and 17%, respectively. The reference point located outside the main transport corridors showed an approximately 11% contribution, both for PM2.5 and PM10 concentrations. The simulations showed that PM pollution is greatly contributed to by on-road mobile sources of emissions in the study area, and especially non-exhaust emissions, which require serious attention in association with their health impacts and the selection of Banská Bystrica as an air quality management area.

Structural Analysis and Optimization of Hybrid Unmanned Amphibian Aerial Vehicle

Hybrid Unmanned Amphibian Aerial Vehicle (HUAAV) is a hybrid unmanned system consisting of a multi-rotor and a hovercraft. Water quality management, hydrographic survey, bathymetric survey and related application areas still employs time consuming and erroneous traditional methods of using boats to access the test sites. The application of unmanned systems will significantly increase the efficiency of this process by getting access to remote locations of both air and water. This paper deals with the design optimization and finite element structural analysis to validate the structural capability of the hybrid amphibian aerial vehicle for operational conditions. The Reserve Factors (RF) for all the components in the amphibian aerial vehicle are calculated and then optimized.

Complex Customer Loyalty Measurement at Closed-Loop Quality Management in B2B Area—Czech Example

The main objective of this article is to present our proposal of complex customer loyalty measurement within external feedback loops as a response of Industry 4.0 concept in the area of advanced quality management for business-to-business (B2B) relationships, as customer loyalty and organisational sustainability are two critical factors for long-term success. To reach the goal, deep literature analysis, special field research, interviews with specialists, and development of a new model of closed-loop quality management systems, which are created for Quality 4.0 environment, were used. A new term, complex customer loyalty, is introduced, and twelve basic steps of its measurement are briefly explained, including a set of loyalty indicators, all regarding specific characteristics of B2B context. Special research confirmed that only about 15% of Czech organisations use some systematic approach to customer loyalty measurement within B2B area. In the majority of Czech B2B organisations, closed-loop quality management systems are mostly in early phases of their development. However, there is no doubt that complex customer loyalty measurement will be an important part of these systems. The proposals presented in this article are mostly universal and should be applied not only to Czech companies.

Parameterized complexity of completeness reasoning for conjunctive queries

Incompleteness management has become a popular research topic and been viewed in many applications in the area of data quality and data management. Traditional methods for handling incompleteness assume data is totally complete or incomplete. However, in practical applications, data is often partial complete, which means that data is not totally complete but some special parts of the data satisfying given semantic specifications are complete. Intuitively, partial complete data can still give complete answers for queries consistent with the semantic specifications. Therefore, it is highly needed to study the fundamental problems for managing partial complete data. However, as far as known by us, there are only few works focusing on this area. The most important and fundamental problem, completeness reasoning, is studied from the aspect of parameterized complexity by this paper. The completeness reasoning problem, TC-QC (Table Completeness to Query Completeness), is first formally defined and studied by Razniewski et al. [1]. Given completeness statements of data, the goal of the TC-QC problem is to determine whether the result of a special query Q is complete, that is to reason query completeness based on given data completeness. Razniewski et al. have shown that the TC-QC problem is NP-hard even for conjunctive queries, and a natural and interesting question is whether or not TC-QC can be solved efficiently by parameterized algorithms. To answer that, the parameterized complexities of completeness reasoning for conjunctive queries are studied by the paper. First, it is shown that, considering the parameterizations defined by the size of query completeness or table completeness, the parameterized TC-QC problem for conjunctive queries is para-NP-complete, which strongly indicate that the TC-QC problems parameterized by the above two parameters do not admit fixed-parameter tractable algorithms. Then, for more special cases parameterized by different constraints on query structures like degree, tree-width and number of variables, the TC-QC problems are still not fixed parameter tractable. Finally, on the positive side, if each data completeness statement has a constant size bound, the parameterized TC-QC problem defined by the query completeness size can be solved by a fixed-parameter tractable algorithm.
