A Search for Magnetized Quark Nuggets (MQNs), a Candidate for Dark Matter, Accumulating in Iron Ore
Authors: VanDevender J. Pace , Sloan T. , Glissman Michael
Published: January 2024

A search has been carried out for Magnetized Quark Nuggets (MQNs) accumulating in iron ore over geologic time. MQNs, which are theoretically consistent with the Standard Models of Physics and of Cosmology, have been suggested as dark-matter candidates. Indirect evidence of MQNs has been previously inferred from observations of magnetars and of non-meteorite impact craters. It is shown in this paper that MQNs can accumulate in taconite (iron ore) and be transferred into ferromagnetic rod-mill liners during processing of the ore. When the liners are recycled to make fresh steel, they are heated to higher than the Curie temperature so that their ferromagnetic properties are destroyed. The MQNs would then be released and fall into the ferromagnetic furnace bottom where they would be trapped. Three such furnace bottoms have been magnetically scanned to search for the magnetic anomalies consistent with trapped MQNs. The observed magnetic anomalies are equivalent to an accumulation rate of ~1 kg of MQNs per 1.2 × 108 kg of taconite ore processed. The results are consistent with MQNs but there could be other, unknown explanations. We propose an experiment and calculations to definitively test the MQN hypothesis for dark matter.

Published: January 2024

We reconstruct type II supergravities by using building blocks of O(d)×O(d) invariants. These invariants are obtained by explicitly analyzing O(d)×O(d) transformations of 10 dimensional massless fields. Similar constructions are performed by employing double field theory or generalized geometry, but we completed the reconstruction within the framework of the supergravities.
Centrosomal Protein 55 (CEP55) Drives Immune Exclusion and Resistance to Immune Checkpoint Inhibitors in Colorectal Cancer
Authors: Wangmo Dechen , Gates Travis J. , Zhao Xianda , Sun Ruping , Subramanian Subbaya
Published: January 2024

Colorectal cancer (CRC) currently ranks as the third most common cancer in the United States, and its incidence is on the rise, especially among younger individuals. Despite the remarkable success of immune checkpoint inhibitors (ICIs) in various cancers, most CRC patients fail to respond due to intrinsic resistance mechanisms. While microsatellite instability-high phenotypes serve as a reliable positive predictive biomarker for ICI treatment, the majority of CRC patients with microsatellite-stable (MSS) tumors remain ineligible for this therapeutic approach. In this study, we investigated the role of centrosomal protein 55 (CEP55) in shaping the tumor immune microenvironment in CRC. CEP55 is overexpressed in multiple cancer types and was shown to promote tumorigenesis by upregulating the PI3K/AKT pathway. Our data revealed that elevated CEP55 expression in CRC was associated with reduced T cell infiltration, contributing to immune exclusion. As CRC tumors progressed, CEP55 expression increased alongside sequential mutations in crucial driver genes (APC, KRAS, TP53, and SMAD4), indicating its involvement in tumor progression. CEP55 knockout significantly impaired tumor growth in vitro and in vivo, suggesting that CEP55 plays a crucial role in tumorigenesis. Furthermore, the CEP55 knockout increased CD8+ T cell infiltration and granzyme B production, indicating improved anti-tumor immunity. Additionally, we observed reduced regulatory T cell infiltration in CEP55 knockout tumors, suggesting diminished immune suppression. Most significantly, CEP55 knockout tumors demonstrated enhanced responsiveness to immune checkpoint inhibition in a clinically relevant orthotopic CRC model. Treatment with anti-PD1 significantly reduced tumor growth in CEP55 knockout tumors compared to control tumors, suggesting that inhibiting CEP55 could improve the efficacy of ICIs. Collectively, our study underscores the crucial role of CEP55 in driving immune exclusion and resistance to ICIs in CRC. Targeting CEP55 emerges as a promising therapeutic strategy to sensitize CRC to immune checkpoint inhibition, thereby improving survival outcomes for CRC patients.

Published: January 2024

Vaccine hesitancy is a common issue for children with immune thrombocytopenia (ITP) in China. The objective of this paper is to assess the immunization statuses of children with ITP, analyze the possible relationship between immunization and thrombocytopenia, and evaluate the safety of immunization after ITP remission. We included 186 children with an ITP history and followed up with them for two years after receiving re-immunization recommendations. The participants had an overall age-appropriate vaccine coverage of 57.9%. Vaccine-associated thrombocytopenia occurred in 99 (53.2%, 95% CI = 46.06–60.26) children ranging from 0 to 34 days following immunization, with 14 vaccines involved. One hundred and fifty-four (82.3%, 95% CI = 76.72–87.54) children were advised to restart immunization, whereas 32 (17.2%, 95% CI = 12.46–23.28) were advised to postpone partial or full vaccination. Following the follow-up, 150 (80.6%, 95% CI = 74.37–85.68) children completed the catch-up immunization, whereas 27 (14.5%, 95% CI = 10.17–20.30) partially completed it. Four patients with thrombocytopenia relapsed following the re-immunization. Incomplete catch-up immunization was related to the factors of chronic thrombocytopenia, vaccine-associated thrombocytopenia, and the relapse of ITP following re-immunization. ITP may occur after immunization with vaccines other than measles-containing vaccines. Re-immunization in children with ITP generally does not result in a relapse, regardless of whether the previous thrombocytopenia was vaccine-associated.

Published: January 2024

Coccidioidomycosis is caused by Coccidioides posadasii (Cp) and Coccidioides immitis (Ci), which have a 4–5% difference in their genomic sequences. There is an urgent need to develop a human vaccine against both species. A previously created recombinant antigen (rCpa1) that contains multiple peptides derived from Cp isolate C735 is protective against the autologous isolate. The focus of this study is to evaluate cross-protective efficacy and immune correlates by the rCpa1-based vaccine against both species of Coccidioides. DNA sequence analyses of the homologous genes for the rCpa1 antigen were conducted for 39 and 17 clinical isolates of Cp and Ci, respectively. Protective efficacy and vaccine-induced immunity were evaluated for both C57BL/6 and human HLA-DR4 transgenic mice against five highly virulent isolates of Cp and Ci. There are total of seven amino acid substitutions in the rCpa1 antigen between Cp and Ci. Both C57BL/6 and HLA-DR4 mice that were vaccinated with an rCpa1 vaccine had a significant reduction of fungal burden and increased numbers of IFN-γ- and IL-17-producing CD4+ T cells in the first 2 weeks post challenge. These data suggest that rCpa1 has cross-protection activity against Cp and Ci pulmonary infection through activation of early Th1 and Th17 responses.

Study on the Spatial–Temporal Variations and Driving Factors of Water Yield in the Yiluo River Basin
Authors: Cao Yongxiao , Zhang Xianglong , Wei Huaibin , Pan Li , Sun Yanwei
Published: January 2024

Water yield (WY) is an significant characteristic that reflects ecosystem services. In order to realize high-quality development, it is vital to explore the spatial and temporal (ST) distribution of WY and its driving factors in the Yiluo River Basin (YLRB) to uphold ecological stability and advance long-term sustainable growth. This paper quantifies WY in the YLRB from 2010 to 2020 using the WY model in the InVEST toolkit. Exploring ST characteristics and driving factors at both the raster and sub-watershed levels, results indicate that the overall WY (average water depth) of the YLRB in 2010, 2015, and 2020 was 26.93 × 108 m3 (136.50 mm), 22.86 × 108 m3 (113.38 mm), and 26.81 × 108 m3 (137.61 mm), respectively. The spatial pattern of watershed WY remains consistent across various periods, illustrating spatial variation in the depth of low WY in the central and western regions and high WY depth in the eastern region. At the sub-watershed level, the Luo River (LR) Basin has the highest contribution (69%) to the WY of the entire basin and served as the principal WY region of the YLRB. Conversely, the Yiluo River section, formed after the confluence of the Yi River (YR) and the LR, has the lowest WY contribution (7%) in the entire watershed. Distinct variations exist in the WY capacity among various land use (LU) types. Construction land (CSL) and unused land (UL) exhibited the highest WY capacity (315.16 mm and 241.47 mm), whereas water area (WA) had the lowest (0.01 mm). WY was significantly positively correlated with slope, precipitation, actual evapotranspiration, percentage of cultivated land, and NDVI. It showed a significant negative correlation with altitude, WA, and population density. This study helps promote the research and development of watershed ecosystem services. It also provides scientific support resolving conflicts between watershed protection and economic development and promoting harmony in the YLRB.
Water Quality Parameter Retrieval with GF5-AHSI Imagery for Dianchi Lake (China)
Authors: Zhang Hang , Hu Wenying , Jiao Yuanmei
Published: January 2024

In response to the rapid changes in the chlorophyll-a concentration and eutrophication issues in lakes, with Dianchi Lake as an example, a remote sensing estimation model for chlorophyll-a, total phosphorus, and total nitrogen in Dianchi Lake was constructed using the three band method and ratio band method based on the visible-light shortwave infrared (AHSI) hyperspectral satellite data from Gaofen 5 (GF-5) and the water quality data collected at Dianchi Lake. The model results were compared with the multispectral data from the Gaofen 1 (GF-1) wide field-of-view (WFV) camera. The accuracy evaluation results indicate that the overall mean absolute percentage error of the remote sensing estimation models for chlorophyll a, total phosphorus, and total nitrogen are 7.658%, 4.511%, and 4.577%, respectively, which can meet the needs of lake water quality monitoring and evaluation. According to the remote sensing simulation results, chlorophyll a is mainly distributed in the northern part of Dianchi Lake, with phosphorus and nitrogen pollution throughout Dianchi Lake and relatively more abundant in the central and southern regions. The pollution is mainly concentrated in the northern and southern regions of Dianchi Lake, which is consistent with the actual situation. Further confirming the feasibility of using GF-5 satellite AHSI data for water quality parameter retrieval can provide new technical means for relevant departments to quickly and efficiently monitor the inland lake water environment.
Change in the Microstructure and Fractal Characteristics of Intact and Compacted Loess Due to Its Collapsibility
Authors: Zhang Shaoying , Shao Shuai , Shao Shengjun , Wu Hao , Wang Zechi
Published: January 2024

This work aimed to examine the fractal dimension and the difference in the law between intact and compacted loess before and after collapse. Uniaxial compression tests were performed to obtain specimens under various vertical stresses, and mercury intrusion porosimetry (MIP) tests were conducted to determine the pore size distribution (PSD). Three models were selected to determine the fractal dimensions based on PSD. As a result, the pores were classified into ultra-micropores (d < 0.1 μm), micropores (0.1 μm < d < 2 μm), small pores (2 μm < d < 10 μm), and large pores (d > 10 μm). When the fractal dimensions were determined using the capillary pressure model, there were three fractal intervals (Ds1, Ds2, and Ds3), with only Ds1 and Ds2 meeting the definition of fractal dimension. Ds1 increased considerably after the collapse, but Ds2 declined. The thermodynamic law-based model presented the best linear fit, and there was only one fractal interval. The fractal dimension Dn increased dramatically after the specimen underwent wet collapse. In conjunction with fractal theory, it revealed that collapse changed the uniformity of the pore system, making the microscopic pores coarser and more intricate after collapse.

L’abandon scolaire chez les adolescents : perspective nord-américaine
Authors: Janosz Michel
Published: January 2024

Le décrochage apparaît comme un indicateur de la qualité d’adaptation sociale des individus. Phénomène ancien, son caractère d’urgence est lié, dans un contexte difficile d’accès à l’emploi, aux risques de troubles personnels ou d’entrée dans la délinquance qui peuvent l’accompagner. Une multiplicité de facteurs peuvent favoriser (ou empêcher) le décrochage. D’où l’intérêt de tenter une typologie des décrocheurs rendant compte de l’hétérogénéité de l’expérience scolaire ou psychosociale, qui seule permettra une intervention différenciée.
Déscolariser le décrochage
Authors: Pain Jacques
Published: January 2024

À la fin des années quatre-vingt et au début des années quatre-vingt-dix le décrochage scolaire a pris une dimension mondiale. Dès cette époque, «l’absentéisme» tenait pour indicateur central dans la question scolaire, avant de voir la violence «à l’école» et les «violences en milieu scolaire» compléter le tableau du «risque social» . La problématique du décrochage nous est venue du Canada, débarquée dans la mouvance des violences «d’école » à dimension psychologique, pointées par le «bullying». L’effet de cette décontextualisation «globalisée» du concept, à la fois politiquement correct, et ses surcharges sémantiques entraînèrent plus de flou dans les seuils de décrochage, mais ouvrirent la vision étroitement quantitative du problème.
The Compliance Issues with Regard to the Registration Procedure of Satellite Constellations
Authors: Liu Huiliang , Sun Qian , Han Siyuan
Published: January 2024

Large constellations, especially at low-Earth orbit, have become a popular solution for global telecommunication. With the proliferation of prospective constellations, more and more satellites will be launched and deployed in the future, which challenges the regulatory framework from several aspects. In the last decades, the International Telecommunication Union (ITU) has established a regulatory framework of space radiocommunication systems for the purpose of securing rights and protection from technical harmful interference of subsequent networks. The well-known steps in the Radio Regulations include the advance publication of information, coordination, notification, and recording of frequency assignments in the Master International Frequency Register. The network registration procedure ran well with the conventional geostationary-satellite orbit (GSO) and non-GSO satellites until the emergence of large constellations. The scope of this paper is to introduce the current approach for ITU to regulate the registration of large constellations and point out the underlying issues. Three issues come from unclear provisions. The first one is whether a non-GSO network can be kept active with fewer satellites on orbit after bringing into use and the milestone requirement. The second issue is whether a non-GSO satellite can be used for bringing into use of different networks. The third issue is whether there should be an error tolerance for the notified orbital parameters in practice. Possible solutions such as postmilestone procedure and tolerance of orbital parameters are discussed. The chance for both ITU and Committee on Peaceful Uses of Outer Space (COPUOS) to explore the potential was also analyzed to implement mutual reference for constellation registration. Furthermore, if the collaboration of the 2 regimes going deep, it could also explore to build up a one-to-one mapping database to figure out the relationship between Master International Frequency Register fillings with actual deployment of large constellations in space.

Deep Dust / The Killing Dark: Extractive Landscapes and Emancipatory Futures
Authors:   Carleton University, Saloojee Ozayr
Published: January 2024

The city of Johannesburg rests on the Witwatersrand (“Ridge of White Waters) Basin - known locally as the “Rand”—an almost 60 kilometre long scarp that also forms a continental divide, draining northern waters into the Indian Ocean and southern waters into the Atlantic. The city on this divide was (and still is) the site of many other divisions - with apartheid among the most famous of these and Johannesburg’s geological history an echo of its racial one. This paper reflects on a (now) two year research and studio teaching project that explores the extractive terrains (and the associated ecologies that link labor, wealth, dispossession, power and emancipation) and ontological readings and re-readings of Johannesburg’s grounds. The studio reflects on the productive and critical role that representation - image making, and architectural and landscape image-making in particular - can embody and carry through the studio structure and assignments. Three initial studio assignments aimed to explore local subjectivities (through the work of photographer Santu Mofokeng), global views (critical and infrastructural mapping) and system ecologies (a machine/tool atlas). The last assignment explored (through a single, deep-section drawing) and proposed a reconciliatory landscape and architectural future. Collectively projects were a framework for thinking about how we might “un/build” understandings and artifacts that help uncover, identify, and propose a reconciliatory superfluity, to use Achille Mbembé’s word, of relations towards an ethical reclamations of landscape.
Decoding Da Vinci's Sketch To The Ottomans: Galata Bridge

Leonardo Da Vinci’s list of accomplishments put him among the world’s greatest artists and inventors. However, over 500 years ago, one controversial sketch wasn’t as much appreciated and has been the topic of many contemporary investigations. Today, more than five centuries later, we are reexamining Da Vinci’s ambitious proposal but not only to look into the structural feasibility of whether or not his design would have been safely constructed, but to delve into the inner workings of Da Vinci’s mind to see if the polymath had prior knowledge of creating stable and efficient forms which has only recently being developed using a computational framework based on the principle of geometrical equilibrium in 3D. Was his sketch just free-handed, something he had done in seconds? Or the renaissance painter and inventor had an intuition that was more than five centuries ahead of its time? Although most historians believe he had no mathematical or geometrical calculation in his design, our study proves otherwise! Through rigorous analysis of Da Vinci’s design, we have found that the polymath had intuitively drawn his sketch according to the principles of geometric design that was developed in 2D almost 400 years after his time and just recently in a 3-Dimensional manner with the help of computational frameworks. This research further continues to explore the potential of Da Vinci’s design with the use of modern materials and methods of construction to see how the design would have been built in our modern time.
Combinatorial Methods: Redundancy in Design and Digital Fabrication
Authors:   University of North Carolina Charlotte, Dickey Rachel
Published: January 2024

This paper outlines combinatorial methods in design which empower architects with systematic approaches for producing novel spatial and formal aggregations that allow for sustainable and practical approaches to fabrication and construction. Combinatorial design methodologies differ from parametric approaches in that they explore part to whole relationships, through additive repetition of discrete parts designed to share tectonic relationships in three-dimensional space. This paper outlines two case study projects that appropriate this methodology and describes the formal, material, and manufacturing possibilities of the approach.
Computational Urban Design: An Exploration of New Urban Science

Published: January 2024

Classic urban design theories and research methods have been limited to qualitative approaches, such as subjective intuition and small-scale surveys. With the emergence of new urban science, adopting big data, virtual reality (VR), and wearable sensors, it is possible to achieve a precise analysis of people’s perceptions and behaviors in urban spaces. In this way, not only will new insights in urban studies be inspired but also high-quality, human-scale space design can be generated. This study constructs a systematic and computational urban design system that covers the three aspects of technical applications, data-informed, evidence-based, and algorithm-driven urban design. First, the data-informed urban design helps identify problems and formulate strategies. Multi-source city data, such as Point of Interest (PoIs)data and AutoNavi map path planning API, help to identify the needs, functions, and characteristics of the citizens. The evidence-based urban design with specific inquiries helps to select the design intervention point and control spatial elements. VR technology, wearable biosensors, and the visualizationSP method are combined to measure space utility. The final algorithm-driven part can use sDNA, UNA, and visualizer to summarize the types of urban spaces, perform morphological analysis and vitality evaluation, and further adjust the design. It can be seen that the application of this framework can make the entire design process more automatic, efficient, and robust under the existing constraints. In addition, it helps the perspective of urban design expand from the previous “top-down” perspective to the “bottom up” perspective, transforming from a two-dimensional to a three-dimensional, obtaining real-time feedback and optimizing design accordingly, emphasizing human perception and human-oriented scale.

This is a process-based design research project that reimagines traditional manual tube bending techniques with the precision and efficiency of digital formative fabrication. Leveraging the positional accuracy of industrial robots using custom tools to bend and interweave metal tubes in geometrically complex and spatially precise loops, the research follows a lineage of projects 1&2 exploring the application of robotic bending of linear elements, primarily in solid-core rod form3. The material limitation of rod diameters conducive to bending constrains the span and length of the members, indirectly limiting the overall size of the resultant product. Solid profiles also prove far from ideal in terms of material efficiency when considering structural cross sections for scaling up to larger inhabitable structures.

Authors: Radzi Muhammad Hafiz Hamdi
Published: January 2024

Open and Distance Learning (ODL) has become an increasingly popular mode of education in Malaysia due to its flexibility and convenience. However, several issues can influence students' performance during ODL method. This paper identifies and discusses five key issues that influence student performance during ODL in Malaysia: technology, learning environment, self-motivation and discipline, support services, and quality of instruction. Access to technology is crucial for successful learning in ODL, and students who lack reliable internet connections or computing devices may struggle to complete their coursework. Additionally, a suitable learning environment, free from distractions and noise, is necessary for students to perform well. Self-motivation and discipline are also vital as ODL requires students to manage their learning independently. Adequate support services such as tutoring, counselling, and academic advising can significantly impact students' performance by providing them with the necessary guidance and support. Finally, the quality of instruction is a critical factor influencing student performance. A well-designed curriculum, engaging course materials, and effective teaching methods are essential for students to stay motivated and engaged. Addressing these five issues can help promote student success in ODL method in Malaysia and improve the quality of education offered through this mode of learning.

Many chemical plants use flammable liquids as raw materials or produce flammable liquids. In both cases, the flammable medium will most likely need to be stored. One option is to use storage tanks. Currently, in Hungary, the fire and explosion protection requirements for upright cylindrical steeltanks are laid down in MSZ 9910-2:1993 and for horizontal cylindrical steeltanks in MSZ 9909-3:1998, supplemented by the MSZ 15633 series of standards. These standards have not changed in the last 30 years and have not followed the innovations in the field, unlike NFPA 497:2021; NFPA 59A:2023; API RP 505:2018; Area Classification Code for Installations Handling Flammable Fluids Part 15:2005 (IP 15); Health and Safety Executive (HSE) HSG 176 Storage of flammable liquid in tanks, 2nd edition:2015 and EIC 60079-10-1:2008. The aim of this study is to compare the conclusions of these standards and to propose a new standard that could be applied in Hungary.

Teknik pengumpulan data dengan cara pengukuran dan menggunakan lembar kuesioner, kemudian data dianalisis secara deskriptif. 
Hasil penelitian menunjukkan bahwa rata – rata intensitas kebisingan yang didapat sebesar 75,78 dBA. Sebanyak 20% tenaga kerja dengan masa kerja lama dan tidak menggunakan APT mengalami penurunan ambang dengar sedangkan sebanyak 100% tenaga kerja, baik masa kerja lama ataupun baru dengan perilaku tidak menggunakan APT mengalami keluhan subjektif kategori sedang dan tinggi.
Intensitas kebisingan pada bagian pencucian ruang laundry rumah sakit Surabaya sudah memenuhi NAB yang telah ditetapkan yakni dibawah 80 dBA, kebisingan yang terjadi tidak sampai berdampak pada penurunan ambang dengar namun berdampak pada gangguan non pendengaran (keluhan subjektif). Saran yang dapat diberikan adalah melakukan pemantauan intensitas kebisingan, perawatan pada mesin secara berkala, dan penggunaan APT pada tenaga kerja

WHO mention about 1.5 million children die each year because diseases that can be prevented by immunization. Immunization is one of the health interventions that has proven to be the cheapest, because it can prevent and reduce the incidence number of morbidity, disability, and death due to PD3I (Ministry of Health RI, 2020). Infants aged 0-11 months must receive complete basic immunization consisting of 1 dose of Hepatitis B, 1 dose of BCG, 3 doses of DPT-HB-HiB, 4 doses of polio drops (OPV), 1 dose of injectable polio (IPV) and 1 dose of measles rubella. In 2020, complete basic immunization in the city of palembang  is 81.9% and this means that it has not reached the 2023 national target of 100%. The immunization coverage of Boom Baru  Health Center reached 96.4%. The purpose of this study was to find out  what factors are related to the coverage of complete basic immunization in children at the Boom Baru Health Center in Palembang City. This study used quantitative methods with a cross sectional approach. Data collectiom used a questionnaire and analyzed univariately to describe distribution and proportion, and bivariate used Chi Square. This study found that there was no relationship between mother’s last  education with complete basic immunization coverage (p = 0.143), and there was a relationship between mother’s knowledge (p = 0.000), Trust (p = 0.000), family support (p = 0.000). This study suggest for health workers  provide counseling and increase  the motivation of mothers regarding the importance of immunization and do monitor the completeness of their immunization, while mothers who have babies should take the time to immunize their chidren.

ABSTRACT
Background: The mosque in Kejapanan Village, Pasuruan Regency has sanitation problems in the form of inadequate physical buildings. Based on a preliminary survey, there was 1 mosque using well water which had an E.Coli content of 650 compared to the required level of 0/100 ml. The aim of this research is to describe the sanitary conditions of mosques in the Kejapanan Village area, Pasuruan Regency.
Method: The design of this research is descriptive observational research, with a cross-sectional approach. The variables studied included the sanitary conditions of mosques and E.Coli parameters of well water in the Kejapanan Village area, Pasuruan Regency. Data collection techniques use observation. The data collected was then analyzed descriptively through table analysis.
Results: Mosque sanitation assessments have been carried out, in the 4 mosques in Kejapanan Village, Pasuruan Regency, there are still mosques that do not meet the requirements. The mosque studied did not have facilities such as prayer carpets and trash cans with lids. Mosque well water samples tested by the UPTD Regional Health Laboratory, resulted in an Escherichia coli (E.Coli) content of 25 - 650 from a maximum level of 0/100 ml so it did not meet clean water quality standards.
Conclusion: Mosque sanitation in Kejapanan Village, Pasuruan Regency, there are still mosques that do not comply with sanitation requirements. For mosque managers, efforts need to be made to improve mosque sanitation and for future researchers, they can carry out research using input variables that are thought to cause contamination of mosque sanitation and sources of clean water for ablution in mosques.

The Effects of Consumer Purchasing Behavioral Characteristics, Decision-Making Disorder, and Consumer Confusion on New Technology Product Purchasing Failure
Authors:   Chungbuk National University, Research Institute of Human Ecology, Huh Kyungok
Published: January 2024

Background/Objectives: Purchasing a new technology product is more difficult or confusing for consumers than purchasing an existing product, and there is a high probability of feeling a sense of failure after purchase.
Methods: this study investigated the factors influencing consumer decision-making disorder, consumer confusion, and a sense of failure after purchasing a new technology product using a regression analysis method. Second, four types of purchasing behavior characteristics of consumers were selected as independent variables, and consumer decision-making disability and consumer confusion variables were used as parameters to determine failure after purchasing new technology products.
Results: The main results of this study are presented as follows. First, as a result of regression analysis, the level of decision- making disorder of consumers was found to be high when the level of household income was low and when there were children. Second, looking at the results of covariate structural analysis, trend-seeking and novelty-seeking tended to increase the level of deci sion-making disability, while planning-seeking and prudence-seeking tendencies lowered decision-making disabili ty. On the other hand, it was found that the pursuit of novelty and fashion increased the level of consumer confusion, while the pursuit of planning and prudence lowered the level of consumer confusion. Third, it was found that decision-making disability and consumer confusion increase the level of consumers' sense of failure after purchasing a new technology product.
Conclusion/Implications: Summarizing the results so far, it can be said that increasing planning and prudence can reduce decision-making obstacles and consumer confusion, ultimately reducing failure after purchasing new technology products. Conversely, since the level of decision-making disorder and consumer confusion are positively affected by the fashion-seeking propensity, it is necessary to reduce the fashion-seeking propensity.

Published: January 2024

Background/Objectives: The purpose of this study is to understand the actual condition of community resources network m the “On-site Myhome Center” and propose a revitalization plan to increase the efficiency of supporting Housing welfare services with the limited resources and manpower of the center.
Methods: The subjects of this study were 14 Housing welfare Professionals placed in the “On-site Myhome Center” of Permanent Public rental housing. It was surveyed as a questionnaire composed of open questions.
Results: Each of the 14 “On-site Myhome Center” subject to this survey is carrying out specialized projects tailored to tenants. It provides continuous and integrated Housing welfare services by deriving optimal resources through organic links with private organizations and public institutions in the local community. Among the tasks of the “On- site Myhome Center” Housing welfare Professionals, most of them recognize the community resources network as important tasks within the third priority, including four who answered that their importance is the first priority.
Conclusion/Implications: For the efficient community resource linkage work of the “On-site Myhome Center”, it is an urgent priority to recruit personnel who are qualified as Housing welfare Professional, not assistants. The lack of space m the “On-site Myhome Center” is also related to the center's internal and external status, so an independent space should be secured and a space for meetings with related organizations should be secured. It is necessary to actively promote the work of “On-site Myhome Center” at home and abroad, and to strengthen specialized projects that do not overlap with those of local social welfare centers or management offices.

Published: January 2024

Background/Objectives: This study analyzed the impact of COVID-19 on the labor income of workers in 16 regions by comparing the time periods of COVID-19 inexperience(2017 2018) and COVID-19 experience(2019 2020). In addition, this study examined the impact of COVID-19 by dividing wage workers and self-employed workers by region one year after the spread of COVID-19.
Methods: This study used data from the Korea Labor Panel Survey of the Korea Labor Institute. Data on individual labor status by year were reconstructed using Korea Labor Panel data from 2017 to 2020. In this study, the impact of COVID-19 on workers' wages in different regions was empirically verified using a time-wise difference-in-difference methodology, with the period before COVID-19 established as the control group.
Results: The analysis revealed that after the outbreak of COVID- 19, the monthly wages of the employees increased in all provinces except Daegu, indicating that the shock period of COVID-19 is entering a recovery phase. However, for self-employed workers, monthly wages decreased in regions such as Seoul, Incheon, and Gangwon.
Conclusion/Implications: The findings reveal that COVID-19 impacts self-employed workers more than contracted employees. Despite the loss compensation policy for the self-employed since 2021, economic difficulties for the self-employed, including debt problems, remain. Therefore, policy support, including financial and tax benefits, are needed in regions with many small business owners are.

Published: January 2024

Background/Objectives: Industrial harness designs have traditionally prioritized safety and protection against physical impact while giving limited consideration to the wearer's body shape. To enhance the comfort of industrial harnesses, this study proposes domestic industrial harness sizing systems based on an analysis of Korean anthropometric measurements.
Methods: Data from the 8th Size Korea anthropometric report(2020-2023) were utilized to propose sizing systems tailored to the Korean body type for industrial harness products. Dimensional analysis involved the direct measurement data of adult men and women aged 20 to 59. The sizing systems of commercially available industrial harnesses were also examined. The product from domestic brand with 3 sizes was selected as a representative design for further analysis.
Results: Through an analysis of waist circumference frequency dis tribution, three sizes were determined: S (66- 161), M (81- 166), and L (96- 172).
Conclusion/Implications: The industrial full body harness sizing system proposed in this study, based on Korean anthropometric measurements, is expected to enhance the fit of harnesses. Furthermore, this study is expected to offer essential data for establishing a rational sizing system from a producer's perspective. This research is significant as it represents the first effort to establish sizing systems for Koreans in full body harness design. Furthermore, it is anticipated that full body harness product designs using this system will not only improve user satisfaction with fit but also enhance ergonomic suitability.
