Authors:   University of the Philippines Los Baños, Acabal Ma. Camille , Yaptenco Kevin , Elauria Jessie , Esguerra Elda
Published: May 2024

Direct measurement of gas transmission rates of coated commodity under controlled environmental conditions is needed in formulating coatings to extend shelf life of fruits. The gas transmission rate of coated commodities, along with its respiration rate can be used to predict the level of modification of internal atmosphere and the quality of the product during storage. Oxygen (O2) and carbon dioxide (CO2) transmission rates of mango (Mangifera indica L. cv Carabao) peel coated with different formulations of chitosan-nanosilica at three storage temperatures were estimated using Exponential Decay Method. The coating was prepared by dissolving chitosan (CS) in aqueous solution of glacial acetic acid (0.25% v/v) and blending with nanosilica (NS) dispersion. The resulting films have microcracks and agglomeration of NS throughout the surface. 0.75% CS at 25°C had the highest gas transmission rate (1.136 mLO2 cm-2 h -1 and 3.243 mLCO2 cm-2 h -1 ) whereas 1% CS+ 0.03% NS at 15°C had the lowest gas transmission rate (0.406 mLO2 cm-2 h -1 and 1.586 mLCO2 cm-2 h -1 ). At constant temperature, increasing chitosan concentration decreases O2 and CO2 transmission rates by almost 44% and 41%, respectively, whereas the incorporation of NS decreases the O2 transmission rate by 10% to 20% and CO2 transmission rate by 5% to 14%. Gas transmission rates were highest at 25°C and lowest at 15°C

A study on site suitability analysis of small water impounding projects (SWIPs) in CALABARZON Region, Philippines was conducted using a GIS-based water resources assessment procedure for optimum water resourceallocation and utilization. The study involved primary data collection through needs and design assessment survey of farmer-respondents utilizing SWIPs, and geo-tagging of existing SWIPs in the CALABARZON region. Secondary data inputs were also gathered from various institutions to generate the thematic maps and the potential suitability maps for SWIPs. Location maps of existing and potential sites for the development of SWIPs in CALABARZON were generated though GIS-based mapping. The generated SWIP potential suitability map was classified as highly suitable, moderately suitable, or marginally suitable. There were eight (8) factors considered in site suitability mapping of SWIP, namely, (1) average annual total rainfall, (2) soil texture, (3) slope, (4) road accessibility, (5) potential irrigable area (PIA), (6) geology, (7) watershed area, and (8) reservoir area. Of the total 350 potential sites identified for SWIP development in the CALABARZON region, 7% were classified as highly suitable, 61% as moderately suitable, and 32% as marginally suitable. The results can serve as a tool for SWIP planning and development to augment irrigation requirements for sustainable food production in the region.

Trendy or Classic? Increasing Sustainability by Increasing Preference for Style Durability
Authors: Smith Hannah Elizabeth , Winterich Karen Page
Published: May 2024

Fast fashion clothing typically has a lower price with a shorter lifecycle, resulting in more frequent purchases than traditional fashion. Consequently, consumption of fast fashion has negative consequences for the environment and society. Consistent with the lower price for fast fashion apparel, it is often lower quality and thus has lower physical durability. However, distinct from physical durability, we introduce the concept of style durability, which refers to the timelessness of the design. We propose style durability can increase clothing lifecycle as timeless clothing can be worn for extended periods without being perceived as “out of style”. In this commentary, we identify several factors that may influence a consumer’s preference for clothing with more style durability, or more classic clothing. Specifically, product-level factors such as hedonic versus utilitarian focus and experiential versus material goods may impact preference for greater style durable clothing. Additionally, consumer characteristics including self-concept clarity, self-concept continuity, and consideration of future consequences may impact the extent to which consumers choose more classic clothing. We offer future research questions that can be studied better understand how to increase consumption of style durable clothing and extend clothing lifecycles.
The design of a faculty research data repository platform conducive to a University of Technology
Authors:   , Zibani Patiswa
Published: May 2024

As significant players in the production of scholarly work, academic researchers are increasingly gathering and producing data rapidly, exceeding the development of the knowledge and skills required for proper data storage and management. However, the focus has typically been on research publication outputs rather than the research data determining the academic's research output. This study conducted an audit survey on research data management in a University of Technology faculty context to gain insight into their research data management practices. The study was guided by the Data Audit Framework (DAF), the Community Capability Model Framework (CCMF), and the User-Centered Research Data Management Framework (UCRDMF). The study utilized an explanatory sequential mixed method research design incorporating quantitative and qualitative components. In the quantitative phase, an online survey was administered to postgraduate students pursuing Master's and Doctoral degrees between 2015 and 2020. On the other hand, the qualitative phase involved conducting a meta-analysis of research repositories across global Higher Education Institutions (HEIs) and conducting online interviews with postgraduate supervisors who play a crucial role in postgraduate study and research administration. The quantitative data were analyzed using the Statistical Package for the Social Sciences (SPSS), while the qualitative data were analyzed using NVivo software. The collected data were then analyzed respectively with theoretical frameworks and existing literature. The findings revealed that managing research data was primarily a personal matter. The main reason for the difficulties was that the faculty lacked a research data management investment. The use of emails, external hard drives, and personal laptops are additional examples that showcased that the faculty had not established centralized systems for managing research. However, participants did recognize the benefits of managing research data, such as scientific advances, enhanced data repurpose, and simplicity for data reusers. Findings also showed that the lack of platforms permitting data sharing and reuse was one of the main reasons that most researchers had not shared or reused other researchers' research data. Researchers, however, wanted to share their data without restrictions. The study's conclusions were also used to create and document a conceptual framework for the faculty research data repository platform. The proposed model aims to guide the conception of a repository that will secure the storage of faculty digital information that can be easily retrieved.

This research aims to improve the quality of learning at MTS Negeri Batang through a Total Quality Management (TQM) approach. This research uses a qualitative method with a case study design. Data collection methods use observation, interviews, questionnaires and documentation by checking data, source triangulation and technical triangulation. This research uses qualitative descriptive analysis techniques, namely a discussion method that attempts to describe symptoms, events and occurrences that occurred during the research. The collected data was then analyzed using data reduction methods, data presentation, and drawing conclusions. From the research results, the right solution to solve the root of the existing problem is the TQM approach which is a new paradigm in a quality approach that will be carried out sustainably in the future. In essence, teachers are not the only cause of low quality education. The facts show that in terms of the pillars of developing quality, relevance and competitiveness, facilities and infrastructure factors (classrooms, libraries, laboratories, etc.), as well as student motivation and the role of parents/community have a very large contribution to the achievement of school quality and graduate of.

Mapping the development of green in gardens over time: is your neighbour’s garden really greener?
Authors: Bouwknegt Lynn , Koomen Eric , Rouwendal Jan
Published: May 2024

Abstract. Private gardens are an important aspect of small urban green space and help provide a wide range of ecosystem services. This contribution is increasingly recognised and several local governments now stimulate residents to replace garden pavements with vegetation. Tracing such greening efforts is difficult, however, because of their small scale and absence in official mapping efforts. Therefore, we propose an approach to map the greening of gardens by analysing a time series of highly detailed aerial photographs. Our approach overcomes several challenges: the temporal variation in the green signal because of seasonal differences in green cover or shade, the small size of gardens and the obstruction of vision by overhanging trees. We present the results of this analysis and assess their accuracy by using a confusion matrix.
Development of a tool to calculate distance for veterinary epidemiological applications
Authors: Cazzaro Mirco , Scolamacchia Francesca , Mulatti Paolo , Ferrè Nicola
Published: May 2024

Abstract. The transmission of infectious diseases is intricately linked to spatiotemporal proximity. Spatial data used in veterinary epidemiology to depict the distribution of disease events typically encompasses pairwise distances between two locations. The Euclidean method is commonly employed to compute such distances. We have developed a tool capable of calculating pairwise distances, considering factors such as orography, the road network, or the land use, given a set of points representing farms or outbreak sites where samples have been collected. The outcome is a three dimensional object comprising six distinct pairwise matrix distances: Euclidean, Haversine, route, route with elevation, orographic/elevation and cost/friction. These distances offers opportunities for exploring novel approaches to integrating the spatial component into epidemiological applications.
Developing a city-specific walkability index through a participatory approach
Authors: Cardoso Matias , Milias Vasileios , Harteveld Maurice
Published: May 2024

Abstract. The extent to which the built environment encourages people to walk in public spaces, hence the quality of being walkable or ‘walkability’ has long been associated with positive outcomes on people’s health. While various studies have developed indices to assess walkability, limited attention has been given to indices that reflect the influence of specific city characteristics on walkability. This study showcases the development of a city-specific walkability index through a participatory approach using Amsterdam as a case study. It explores the viewpoints of urban designers and policy-makers who work or reside in Amsterdam on what constitutes a walkable street and identifies the most significant walkability factors for Amsterdam. These factors are then quantified based on open-access datasets and integrated into a street-level weighted walkability index. The resulting walkability index underscores the importance of factors such as traffic and crime safety, quality of the pedestrian infrastructure, and proximity to public amenities in shaping residents’ decisions to walk in specific public spaces. Finally, this research underscores the importance of involving individuals through participatory methods, considering subjective perspectives, and acknowledging shared experiences within particular groups and spaces when assessing walkability.

Published: May 2024

Abstract. This paper explores the use social media data from Twitter to capture perceptions of neighbourhood characteristics, in relation to gentrification. It does this by defining a rudimentary lexicon of words associated with gentrification which was used to calculate gentrification scores for geo-located tweets. These were then interpolated to create the surfaces describing the spatial and temporal patterns of gentrification. There are a number of limitations to the methods used in this study, which are discussed and a number of related areas of future work are indicated.
Multimodal Geo-Information Extraction from Social Media for Supporting Decision-Making in Disaster Management
Authors: Hanny David , Resch Bernd
Published: May 2024

Abstract. Effective decision-making in natural disaster management relies heavily on a comprehensive understanding of the situation in affected areas. Social media has been established as a tool to monitor human response and damage assessment. Given the vast amounts of data available, computational methods such as topic modelling are typically employed to reduce information complexity. However, these methods mostly neglect aspects such as geographic location and emotional response, which frequently results in sequential workflows of initial semantic filtering and subsequent spatial or spatio-temporal analysis. This study presents a novel approach for multimodal information extraction from geo-social media data for aiding decision support in disaster management. The method leverages a spatial, temporal, semantic, and sentiment-based clustering approach of social media posts to extract clusters that provide insights into disaster-related content. A case study in the Ahr Valley region in Germany demonstrates the method’s effectiveness in providing actionable insights for disaster response and management. The approach offers a tool for the quick assessment of disaster-related information from social media, potentially aiding timely and informed decision-making.
Combination of Augmented Reality and 3D Geographic Information: A User perspective towards Feature-Based Augmented Reality
Authors: Huang Te-Lun , Hong Jung-Hong
Published: May 2024

Abstract. Augmented Reality (AR) has become widely popular due to its innovative interface and immersive interactions, appealing to both experienced professionals and novice users, making it a versatile technology in various fields. Combining AR with Geographic Information Systems (GIS) has emerged as a valuable approach for enhancing the information available in AR-based applications. In this study, we propose an application framework that integrates Ultra WideBand (UWB) indoor positioning, feature-based 3D GIS, and AR. The feature-based AR scenes were designed to provide enriched information and consider the effects of object occlusion to enhance the user experience. Additionally, a transparent mode allows users to move obstacles based on the 3D features creates an intuitive and adaptable interaction environment. This research demonstrates the effectiveness of the proposed framework in achieving real-time applications such as facility management, surveillance, and object search in indoor environments.
Locality and transferability: examining pre-built lexicons to elicit landscape values from natural language
Authors: Kong Inhye , Purves Ross S.
Published: May 2024

Abstract. Landscape values are perceived through complex interactions between people and their surroundings, and understanding such values is essential for policy. Previous research to explore landscape values through text analysis often relies on developing lexicons, which serve as value classification rules. However, it is unclear how transferrable such lexicons are between locations of differing environmental and cultural conditions. In this work, we examine the transferability of lexicons from previous studies: one on based on Geograph data to contain natural language in the UK and another on based on TripAdvisor in the context of US national parks. Both lexicons have typologies for 1) attractiveness/aesthetics of landscape and 2) natural elements/mammal species/biological values of landscape. We apply these lexicons to a text corpus built with the Guardian’s Country Diary. Our initial findings were spatial distributions of lexical matches, along with match ratios and keywords at county level in the UK. Then we zoomed in to compare the lexical performance to learn that larger lexicons do not guarantee better results when the context mismatches. Indeed, there is a room for transferability of lexicons; nonetheless, it is crucial to acknowledge that lexicons are sensitive to locality, urging to consider site-specific biophysical and sociocultural difference in applying pre-built lexicons.
getFeedback!: Feedback-Based Learning while Identifying a Caravan Site Location
Authors: Nuhn Eva , Spang Laura , Timpf Sabine
Published: May 2024

Abstract. A new teaching and learning approach has been implemented in the BSc course Geodata - Geoinformation - Geoknowledge. This course is part of both the Geography and Geoinformatics bachelor programmes at the Faculty of Informatics at the University of Augsburg. In the course we combined a case study with a new tool - get- Feedback! - that allows both tutorial and peer feedback. In the case study students had to find an optimal location for a caravan site. It was divided into the following tasks: identification of criteria for the location of a caravan site, identification of data sources for the criteria, and design of the analysis workflow including GI methods. In addition, tutorial and peer feedback was provided using the getFeedback!-Tool. Students were asked to complete a pre- and post-test to assess learning. Analyses of the test results showed that the more tasks students completed, the better they performed on the post-test. We conclude that getFeedback! combined with a case study is a valid tool to support students in the acquisition of professional competences.
Using a Hybrid Semi-Integrated Spatial Allocation Model to Model Future Housing Allocation
Authors: van Bemmel Bas , Itova Irena , Bax Ismay
Published: May 2024

Abstract. In this paper we present the semi-integrated land use model Land Use Scanner 2.0 (in Dutch: RuimteScanner 2.0) to model the future growth of housing in the Netherlands, by 2050. The modelling was done in the scope of four future scenarios which were developed for the Spatial Outlook 2023, a study carried out between the period of 2021 and 2023, by the Netherlands Environmental Assessment Agency (PBL). The scenarios in the Spatial Outlook 2023 present different futures of land use, based, among other things, on the Dutch ambition to develop sustainable land use and to reduce carbon footprint and natural resources depletion by 2050. At the same time, several socioeconomic challenges are central drivers in the Outlook, such as the housing shortage and the developing economy, as well as the progressive shift to renewable energy sources and sustainable farming, all placing claims on the future land use. The results discuss two of the four future scenarios and show both spatial and quantitative variations between the scenarios in the allocation of houses, indicating the importance of differences in living conditions and housing preferences. The possibilities of the Land Use Scanner 2.0 to serve as a tool for policy dialog and design, rather than prediction, is presented.
EyeCatchingMaps, a Dataset to Assess Saliency Models on Maps
Authors: Wenclik Laura , Touya Guillaume
Published: May 2024

Abstract. Saliency models try to predict the gaze behaviour of people in the first seconds of their observation of an image. To assess how much these models can perform to predict saliency in maps, we lack a ground truth to compare to. This paper proposes EyeCatchingMaps, an open dataset that can be used to benchmark saliency models for maps. The dataset has been obtained by recording the gaze of participants looking at different maps for 3 seconds with an eye-tracker. The use of EyeCatchingMaps is demonstrated by comparing two different saliency models from the literature to the real saliency maps derived from people’s gaze.

Abstract. African elephants (Loxodonta africana) are the largest extant terrestrial mammals, with bodies containing enormous quantities of nutrients. Yet we know little about how these nutrients move through the ecosystem after an elephant dies. Here, we investigated the initial effects (1–26 months post-death) of elephant megacarcasses on savanna soil and plant nutrient pools in Kruger National Park, South Africa. We hypothesized that: (H1) elephant megacarcass decomposition would release nutrients into soil, resulting in higher concentrations of soil nitrogen (N), phosphorus (P), and micronutrients near the center of carcass sites; (H2) carbon (C) inputs to the soil would stimulate microbial activity, resulting in increased soil respiration potential near the center of carcass sites; and (H3) carcass-derived nutrients would move from soil into plants, resulting in higher foliar nutrient concentrations near the center of carcass sites. To test our hypotheses, we identified 10 elephant carcass sites split evenly between nutrient-poor granitic and nutrient-rich basaltic soils. At each site, we ran transects in the four cardinal directions from the center of the gravesite, collecting soil and grass (Urochloa mosambicensis) samples at 0, 2.5, 5, 10, and 15 m. We then analyzed samples for CNP and micronutrient concentrations and quantified soil microbial respiration potential. We found that concentrations of soil nitrate, ammonium, 15N, P, sodium, and potassium were elevated closer to the center of carcass sites (H1). Microbial respiration potentials were positively correlated with soil organic C, and both respiration and organic C decreased with distance from the carcass (H2). Finally, we found evidence that plants were readily absorbing carcass-derived nutrients from the soil, with foliar %N, 15N, iron, potassium, and sodium significantly elevated closer to the center of carcass sites (H3). Together, these results indicate that elephant megacarcasses release ecologically consequential pulses of nutrients into the soil, which then move into above-ground nutrient pools in plants. These localized nutrient pulses may drive spatiotemporal heterogeneity in plant diversity, herbivore behavior, and ecosystem processes.
Long-term (2010–2021) lidar observations of stratospheric aerosols at Wuhan, China
Authors: He Yun , Jing Dongzhe , Yin Zhenping , Ohneiser Kevin , Yi Fan
Published: May 2024

Abstract. Stratospheric aerosols are long-lived and play a critical role in the global radiation budget. Over the past decade, contributions to stratospheric aerosols from different sources have changed due to weaker volcanic activity and more frequent wildfire events. However, long-term observations of stratospheric aerosols and monitoring of major emission events remain insufficient, particularly at middle and low latitudes. In this study, we analyze the vertical distribution, optical properties, and radiative forcing of stratospheric aerosols using observations from a ground-based polarization lidar in Wuhan (30.5° N, 114.4° E) from 2010 to 2021. The stratospheric aerosol optical depth (sAOD) generally stabilized around 0.0023 without significant annual variation. Several cases of volcanic aerosol and wildfire-induced smoke were observed. Volcanic aerosols from the Nabro (2011) and Raikoke (2019) eruptions (both in boreal summer) increased the sAOD to 4.8 times the background level during the stratospheric-quiescent period (January 2013 to August 2017). Tracers of smoke from the Canadian wildfire in the summer of 2017 was observed twice: at 19–21 km on 14–17 September and at 20–23 km on 28–31 October, with plume-isolated AOD of 0.002–0.010 and particle linear depolarization ratio δp of 0.14–0.18, indicating the dominance of non-aged smoke particles. During these summertime events, the injected stratospheric aerosols were captured by the large-scale Asian monsoon anticyclone (AMA), confining the transport pathway to mid-latitude Asia. On 8–9 November 2020, smoke plumes originating from the California wildfire in October 2020 appeared at 16–17 km, with a plume-isolated AOD of 0.007 and a mean δp of 0.13. Regarding seasonal variation, the sAOD in the cold half-year (0.0026) is 24 % larger than in the warm half-year (0.0021) due to stronger meridional transport of stratospheric aerosols from the tropics to middle latitudes. The stratospheric radiative forcing was -0.05 W·m-2 during the stratospheric-quiescent period and increased to -0.28 W·m-2 when volcanic aerosols were largely injected. These findings contribute to our understanding of the sources and transport patterns of stratospheric aerosols over mid-latitude Asia and serve as important database for the validation of model outputs.

Untuk mengetahui beban tanah biasanya di lakukan pada sebuah alat uji CBR pada lab, selain itu hasil perolehan yang di dapatkan dari uji tersebut masih manual dan tidak dapat disimpan ke dalam komputer, dengan adanya aplikasi CBR ini hasil yang di dapatkan dapat disimpan ke dalam sebuah komputer dan dapat dilihat berulang sesuai dengan kebutuhan. Metode penelitian yang digunakan adalah R&D dan menghasilkan sebuah produk yaitu software dan hardware. Perangkat lunak menggunakan C# dan perangkat kerasnya menggunakan Arduino. Dengan menggunakan aplikasi ini operator hanya memasukkan data yang sudah di siapkan pada aplikasi dan secara otomatis akan menghasilkan nilai yang dapat dilihat oleh operator, selain itu terdapat grafik yang dapat dilihat dan hasilnya disimpan ke dalam komputer dan hasil ini berupa file excel dan PDF. Hardware menggunakan arduino untuk menyambungkan ke dalam mekanik. Dengan adanya aplkasi ini pencarian perhitungan CBR menjadi terkomputerisasi.

Koperasi simpan pinjam mempunyai peran penting dalam menyediakan layanan keuangan bagi masyarakat. Namun, masih banyak koperasi yang menghadapi tantangan dalam mengelola data transaksi dan aksesibilitas anggotanya. Koperasi simpan pinjam BMT An-Najah masih menggunakan sistem manual dimana data anggota, data simpan pinjam, dan laporan dikelola dengan cara manual. Hal ini dapat menyebabkan kesulitan dalam menyimpan dan mengelola data secara akurat dan efisien. Kemudian, proses pelaporan keuangan, laporan kredit, dan laporan lainnya seringkali memakan waktu dan rawan kesalahan. Data yang disimpan secara manual dapat dilihat atau disalah gunakan oleh orang yang tidak berwenang. Dokumen manual bisa juga rusak atau hilang, sehingga saaat dibutuhkan tidak ada. Penelitian ini mempunyai fungsi untuk membuat rancangan dan kemudian akan diimplementasikan dengan tema sistem informasi koperasi simpan pinjam berbasis web di Baitul Maal Wat Tamwil (BMT) An-Najah. Agar pelayanan kepada anggota bisa meningkat menjadi lebih baik lagi. Proses observasi atau kunjungan langsung dilakukan untuk mengumpulkan data, wawancara, dan juga penelitian kepustakaan. Metode waterfall digunakan peneliti dalam mengembangkan system penelitian yang ada. Tahapan peengembangan system meliputi analisis kebutuhan, perancangan sistem, implementasi, pengujian, dan evaluasi. Hasil dari penelitian ini adalah rancangan dan implementasi sistem informasi koperasi simpan pinjam secara online yang terintegrasi terhadap database untuk mengelola data yang terjadi yaitu simpan pinjam yang dilakukan anggota, data anggota beserta laporan keuangan. Sistem ini memungkinkan anggota koperasi untuk mengakses informasi simpanan, pinjaman dan riwayat transaksi melalui antarmuka web yang mudah digunakan dan responsif.

Tindakan kekerasan terhadap perempuan dan anak seringkali terjadi di kota metropolitan, termasuk Kota Medan. Fenomena ini merupakan suatu bentuk pelanggaran hak asasi manusia yang bisa menimpa siapa pun, tanpa memandang status sosial, ekonomi, atau tingkat pendidikan. DP3APMP2KB memiliki kewenangan untuk memberdayakan perempuan, melindungi anak-anak, serta melaksanakan program pemberdayaan masyarakat dan pengendalian penduduk melalui keluarga berencana. Namun, pelaporan insiden kekerasan terhadap perempuan dan anak masih dilakukan secara manual, menyebabkan kesulitan bagi korban yang harus datang langsung ke kantor, terutama jika mereka berada jauh dari lokasi kejadian. Guna menanggulangi persoalan tersebut, dibuat suatu sistem pelaporan berbasis Android. Tujuan dari sistem ini adalah untuk memudahkan penduduk Kota Medan dalam melaporkan insiden kekerasan melalui layanan pengaduan online. Disamping itu, sistem ini dilengkapi dengan kemampuan deteksi lokasi otomatis guna menjamin ketepatan informasi terkait lokasi pengaduan. Penyusunan sistem ini melibatkan pendekatan Research and Development (R&D) serta pendekatan waterfall sebagai metode pengembangan sistem, dengan mengumpulkan informasi melalui proses wawancara dan menguji coba sistem yang telah dikembangkan. Dari hasil uji coba sistem menggunakan metode blackbox testing, sistem beroperasi sesuai dengan desain yang telah ditetapkan dan dapat digunakan oleh masyarakat secara luas untuk menyederhanakan proses pelaporan tindak kekerasan terhadap perempuan dan anak di wilayah Kota Medan.
