Authors: Šečić Sadeta , Hardaga-Muzurović Anela
Published: December 2023

Introduction: Engaging in sports is crucial for maintaining and enhancing the health of both children and adults. However, it can also be a cause of injuries with temporary or permanent consequences. The primary causes of sports injuries are mechanical forces acting during intense physical exertion. A
significant number of sports injuries involve the stomatognathic system, often occurring suddenly and unexpectedly, accompanied by pain and bleeding. The complexity of injuries depends on the type of sport, the athlete's age, and the force's strength, leading to serious aesthetic, functional, psychological, and economic consequences for the injured.
Purpose of the study: The purpose of the study is to highlight the significant role of sports in physical and mental health, while also addressing potential injuries that may occur during sports activities, with a particular focus on dental and surrounding tissue injuries. The study emphasizes the importance of preventing traumatic and non-traumatic damage to dental tissues and surrounding structures through the mandatory use of sports mouthguards.
Methods: This review article focuses on enriching knowledge about dental traumas caused by sports injuries, their prevention, and trends in the therapy of dentoalveolar traumas.
Results: In this work, the authors aimed to briefly summarize, analyze, and present the latest available information from contemporary literature dealing with dentoalveolar traumas, including their causes, diagnosis, and treatment, while emphasizing the importance of prevention.
Conclusion: Sports injuries, with a specific emphasis on injuries to the stomatognathic system, whether occurring in recreational or competitive sports, require a serious approach in terms of prevention, diagnosis, and therapy. The education of sports professionals, coaches, sports doctors,
parents, and athletes themselves on providing first aid for the occurrence of dentoalveolar traumas is of great importance.
The Impact of the COVID-19 epidemic on Fintech
Authors: Kong Yingru , Wu Jun
Published: December 2023

Fintech is a mainstream trend in digital transformation and it is an important strategic goal adopted by countries to help the real economy. The sudden COVID-19 epidemic has a significant impact on the global economy and pushes the development of Fintech to a new stage. This paper tries to explore the impact of the COVID-19 epidemic on Fintech innovation and regulation by collecting relevant literature from China Knowledge Network and Web of Science, and applying bibliometric methods such as literature quantity statistics and keyword mutation. The study found that: 1) after the outbreak of the COVID-19 epidemic, the number of literatures related to financial technology has increased significantly, and Fintech has become a research hotspot for scholars; 2) from the perspective of the research body, scholars have shifted their interpretations of the connotation of Fintech from conceptual analysis to practical exploration; 3) from the perspective of research content, the COVID-19 epidemic has promoted the technological innovation and application of Fintech, and the results of this field of research have been more fruitful. However, the economic downturn crisis brought by the COVID-19 epidemic has forced regulators to adopt loose regulatory policies, which led to a decline in scholars' attention to financial technology regulation for the regulation of financial technology and a slight lack of research enthusiasm. In the future, sustained efforts should be made to pay attention to the research on Fintech regulation, strengthen the connection between macro and micro perspectives of the discipline, and develop a personalized development path for Fintech.

Authors: Garcia Stephanie Suzanne S. , Kim Changzoo
Published: December 2023

The prevalence of myopia in children and juveniles has increased significantly in Korea and worldwide; in particular, the rates of myopia and high myopia in East Asia have grown rapidly. Myopia is easily corrected with spectacles or contact lenses. However, as children grow and mature, myopia can progress irreversibly and lead to vision-threatening complications. Thus, the prevention of myopia progression is an essential treatment goal. Many treatment strategies are being employed, including atropine eyedrops, specialized glasses, and orthokeratology (Ortho-K) lenses. Ortho-K is an effective treatment in managing myopia progression by lowering the rate of increase in refractive error and axial length. In this article, we review Ortho-K as a treatment for myopia progression, its history, mechanism, treatment regimen, and safety profile.
Христијанизација међу Арабљанима у првом миленијуму Цркве
Authors: Тубин Славиша
Published: December 2023

Рад се бави христијанизацијом Арабљана у интервалу од апостола до краја првог миленијума Цркве. Основно питање рада је идентификација општих крштењских токова међу арабљанским племенима. У време проповеди светих апостола полако се рађа и изграђује хришћанство међу Арабљанима. Од прве беседе на Педесетници, преко мисије апостола Павла, Вартоломеја и неколицине других апостола из броја дванаесторице и седамдесеторице, могу се пратити помени покрштавања. Прва значајнија црквена јурисдикција везана за Арабљане јесте Митрополија Бостре. Од IV до VI века на византијским границама се смењују христијанизована племена арабљанских федерата међу којима се нарочито истичу Гасаниди. Појава мухамеданства и војни порази Византије условили су не само губитак великих територија, него и хришћанства арабљанског становништва на њима. Јачањем Византије долази до феномена рехристијанизације Арабљана, попут племена Бану Хабиб које емигрира на ромејске територије. Мисија Никона Метаноита у X веку заслужна је за рехристијанизацију Крита, о чему сведочи граничарска епика поменуте ере.

Published: December 2023

Atoms in crystals will generate thermal diffuse scattering during thermal vibration. Thermal diffuse scattering analysis has great potential applications in condensed matter physics and material science research. Scandium oxide (Sc2O3) has unique physical and chemical properties, which make it have high research and application value. In this work, X-ray diffraction experiment is performed on Sc2O3 at room temperature of 26℃. The thermal diffuse scattering intensity exhibits a clear vibrational shape. The full diffraction back-based intensity equation of Sc2O3 is expanded, and the theoretical value of the thermal diffuse scattering intensity is calculated until the full diffraction back-based intensity spectrum of the 14th nearest atom (r = 0.3816nm) is calculated. By fitting the theoretical value to the experimental value, we can see the inter-atomic thermal vibration correlation effect μ values corresponding to the nearest neighbor atom to the 7th nearest neighbor atom, the values of distance r from the nearest neighbor atom to the 7th nearest neighbor atom are 0.2067, 0.2148, 0.2161, 0.2671, 0.2945, 0.3229 and 0.3265nm, respectively, corresponding to their inter-atomic thermal vibration correlation effect μ values of 0.64, 0.63, 0.62, 0.61, 0.60, 0.58 and 0.57. Research result shows that the intensity of thermal diffuse scattering in Sc2O3 is closely related to the atomic thermal vibration, the most significant influence on the vibration shape of thermal diffuse scattering intensity is the thermal vibration correlation effect between the 7th nearest atom Sc1-Sc2. Inter-atomic thermal vibration correlation effect μ values will provide important parameters for studying the mechanical and thermal properties of materials, laying the foundation for the next-step calculating specific heat and interatomic force constant, and thus playing a crucial role in the use and development of materials.
“Trembling Moments”
Authors: Hauen Mali , Klungland Monica
Published: December 2023

In this article, the authors investigate making data with pupils in the kulturskole through the exploration of a performative paradigm. There seems to be a lack of knowledge concerning how the pupils see their place in and engagement with the kulturskole. When we started working with the pupils, a request emerged to not only observe and interview them, but also to hear their stories and understandings of being with the kulturskole. These processes are, throughout the article, described and understood as methodologically developmental when working with pupils. We attempt to bridge a qualitative approach into a post-qualitative performative thinking about making data. The article contributes explorations into what data can be and how to make data with pupils.
Effect of Compartment Height with Fire Source on Horizontal Vent Flow and Temperature Distribution
Authors: Kim Yun Young , Lee Chi Young
Published: December 2023

The effect of compartment height with a fire source on the horizontal vent flow and temperature distribution was numerically investigated. Two compartment heights were examined, namely 1.1 m (H1.1) and 5.5 m (H5.5). Horizontal vent areas were set at 1% (HV01) and 10% (HV10) of the floor area, and fire sources were positioned at the center (FSC) and side (FSS). H1.1 exhibited a larger mass flow rate and higher velocity of vent flow than H5.5 for FSC cases with HV01 and HV10. In the case of HV01 with FSS, the mass flow rates between H1.1 and H5.5 were comparable. However, in the case o f HV10 w ith F SS, H5.5 d emonstrated a larger m ass flow r ate than H 1.1. V ent flow v elocities a ppeared similar between H1.1 and H5.5 for FSS cases with both HV01 and HV10. Meanwhile, H1.1 exhibited a higher temperature distribution than H5.5 for HV01 cases with FSC and FSS. For HV10 with FSC, H5.5 showed a higher temperature distribution than H1.1. Conversely, for HV10 with FSS, the opposite trend was observed. The previous correlation overestimated the results of the present numerical simulation regarding the fire plume centerline temperature rise. It was speculated that mixing within the compartment affected the trend of fire plume centerline temperature rise.

Published: December 2023

Fire and nonfire experiments are required to observe the response characteristics of photoelectric smoke detectors; however, repeating all experiments by changing the structure and configuration of photoelectric smoke detectors is time-consuming and expensive. No simulations have been performed to evaluate the response characteristics of photoelectric smoke detectors. In this study, multiple-scattering-based optical simulations were performed to investigate the response characteristics of a photoelectric smoke detector. The radiant energy of light propagating in various media (white smoke, black smoke, water vapor, and dust) with different particle sizes and refractive indices was measured using a photodetector as a function of concentration. Multiple-scattering-based optical simulations that can analyze the response characteristics of photoelectric smoke detectors without fire or nonfire experiments are expected to be actively used for developing new smoke detectors. In addition, the results for the nonspherical soot particles can be analyzed via multiple-scattering-based optical simulations using the discrete dipole approximation method.

Authors: Oh Chan-Wook , Kim Ji-Hun , Oh Ryun-Seok , Choi Jun-Ho
Published: December 2023

Downdrafts are generated indoors because of the water supply and exhaust equipment installed in the clean room of the MLCC factory. In the event of a fire, this downdraft may interfere with the exposure of combustion products, such as heat, smoke, and toxic gases generated from the fire source, to the smoke detector installed on the ceiling. There is a high risk of this adversely affecting people and damaging property, depending on the diffusion of the combustion product. In this study, we analyzed the smoke diffusion patterns according to the operation methods of the supply and exhaust facilities. Modeling was performed using a fire simulation program, and the performance of the water supply and exhaust facilities installed at the analysis site were investigated based on the actual testing, adjusting, and balancing test results to increase the reliability of the modeling results. The analysis indicated that the downdraft from the air-conditioning supply system prevented smoke from the fire source from spreading to the ceiling.

Authors: Oh Chan-Wook , Kim Ji-Hun , Oh Ryun-Seok , Choi Jun-Ho
Published: December 2023

A circulating airflow was generated inside the clean room of an MLCC factory. This airflow affects the movement of combustion products (such as heat, smoke, and toxic gases) when a fire breaks out, and there is a risk of delaying the time required to detect the fire. In this study, testing, adjusting, and balancing were conducted for an actual MLCC plant clean room to analyze the effect of the circulating airflow inside the clean room during fire spread. In addition, the optimal detector location that reduces the time required for smoke detection was determined using a fire simulation program.

Authors: Lee Chang-Heon , Zhang Yu , Shin Weon Gyu
Published: December 2023

Biosafety Level 3 (BL-3) research facilities should maintain negative pressures to prevent the propagation of bioaerosols to the atmosphere and protect researchers and the surroundings from exposure to bioaerosols. Therefore, it is necessary to investigate the influence of smoke and heat on the pressure inside a BL-3 research facility during a fire. The aim of this study was to investigate how the internal pressure in a BL-3 research facility changes during a fire incident. The CFAST simulation results showed that the internal pressure in the laboratory facility rapidly increased at the onset of the fire and continued to increase until the neighboring door was opened. The findings emphasize the need to extinguish a fire at the early stage of the fire to safeguard BL-3 research facilities.
Ugulendu: tambores, sonajas, cantos y sonofanías de la espiritualidad garífuna guatemalteca
Authors: Pérez Guarnieri Augusto
Published: December 2023

En este texto presento un análisis simbólico de la música de la espiritualidad de la población garífuna de Livingston, Guatemala desde la antropología de la experiencia y la perspectiva de sonido-en-el-mundo. A tal efecto comienzo con una presentación de este grupo étnico, el marco teórico-metodológico que sustenta la investigación y una breve revisión sobre los antecedentes referidos a esta población. Luego describo el chugú –ceremonia de culto a los ancestros– y los aspectos clave referidos a la musicalidad de estos rituales, explorando sus materiales, prácticas y performers. Sostengo que el ugulendu –género musical ceremonial– se presenta como una condición cultural determinante de la eficacia comunicativa con los espíritus y que el lanigi garawoun no solo es el tambor principal de estas prácticas, sino que representa el núcleo central de la cultura garífuna. Se trata de una música poderosa que afecta y moviliza la vida de las personas que la experiencian. Los modos de acción, interpretación y transmisión de los toques de tambor, sonajas y cantos liderados por tamboreros –doümbrias– y cantantes –gayusa– involucran la agencia de los espíritus a través de revelaciones acústicas o sonofanías y se configuran como experiencias de conocimiento que vehiculizan significados constitutivos de la matriz identitaria garífuna.
Los gustos estragados: una tonadilla compostelana de 1799
Authors: Gándara Feijóo Javier
Published: December 2023

La tonadilla, nacida y cultivada ampliamente en Madrid, fue un género escénico-lírico cuyo desarrollo ha sido documentado en otras zonas del planeta, especialmente Cataluña, Cuba, México, Perú y Venezuela. No obstante, su presencia en Galicia permanece sin tratar hasta el momento. En este artículo se estudia la primera y única tonadilla creada en el noroeste peninsular ibérico de la que tenemos noticia. Partiendo de una metodología cualitativa, se trabajan aquí diversos aspectos: la música elaborada en 1799 por Melchor López (maestro de capilla de la Catedral de Santiago de Compostela), la letra preexistente tomada de un escrito homónimo de Tomás de Iriarte (de él no se conoce otra partitura) y el contexto de representación de la pieza (atendiendo a la reforma teatral ilustrada que en ese mismo año se aprueba en Madrid). Entre los resultados más destacables, cabe decir que esta obra rompe con varias características atribuidas a la tonadilla como género escénico: la pieza consta de una estética clásica en vez de barroca, fue creada para ambiente doméstico (no propiamente teatral) y se adapta a Galicia por incorporar dentro de las seguidillas epilogales una muiñeira.

Lean in the Public Sector.
Authors: Alarcón Luis F.
Published: December 2023

The Architectural, Engineering, and Construction Industry (AEC) is a critical socio-economic activity that is responsible for 8% of the GDP in the world, in parallel, it also is responsible for the generation of 100 million jobs worldwide. In this context, the generation of value is driven by the execution of capital projects. Nonetheless, despite its importance, the sector´s productivity historically is behind other industries, and poor performance of projects is often the norm rather than the exception. The running of projects in the Public Sector is not immune to these issues. An effective strategy to address this condition is the use of the Lean approach.

Thus, this special issue of the Revista de Ingeniería de Construcción is focused on providing insight into the application of Lean in the Public Sector (LIPS). Articles evidencing the results of LIPS in the United States, UK, Finland, and Chile are presented as part of this effort. Following this premise, the authors who contribute to this special issue have provided an inspiring insight into the use of LIPS around the world evidencing the potential of its outcomes. Despite the progress and the encouraging results, much work is still required to widespread the benefits of this approach.

Published: December 2023

Cardiovascular Diseases (CVD) are a major public health problem worldwide. They continue to be one of the leading causes of death worldwide, and it is alarming that these diseases are becoming more common in people of the young age group. Although various risk factors have been proposed, smoking, dyslipidemia, and hypertension are prominent emerging risk factors in the young. The primary pathogenic mechanism for most cardiovascular disorders, such as coronary artery disease, peripheral vascular disease, heart failure, and Myocardial Infarction (MI), is atherosclerosis. Plaque rupture is the most common cause of MI, although distinctive symptoms such as plaque erosion, coronary microvascular dysfunction, spontaneous coronary artery dissection, and drug-related coronary spasm are more common in this age range. Various lifestyle factors, including, but not limited to, physical inactivity, tobacco use, alcohol consumption, poor eating habits, and drug abuse, contribute to the development of comorbid conditions such as hypertension, hypercholesterolemia, obesity, and diabetes, increasing the likelihood of having heart disease. To mitigate the societal impact of CVD and promote a healthier future for the next generation, proactive measures, such as regular physical activity and a balanced diet, are essential. This will be addressed in terms of lifestyle, environmental, physiological, pathological, and psychological aspects.

Authors: Katha Itisha , Priya Nivedita
Published: December 2023

Introduction: Thyroid disorders, particularly hypothyroidism, are the most common thyroid disorders in India, affecting one in ten adults. Autoimmunity may play a significant role in the progression of hyperlipidaemia, which is one of the recurrent issues associated with thyroid disorders. Although serum lipids have been proven to control immunological and inflammatory responses, little is known about their relationship to thyroid autoimmunity. Aim: To investigate the association between Thyroid Peroxidase Antibody (anti-TPO) and serum lipid parameters among patients diagnosed with hypothyroidism. Materials and Methods: A hospital-based cross-sectional study was conducted at Parul Sevashram Hospital in Vadodara, Gujarat from November 2022 to May 2023. A total of 103 patients with hypothyroidism were included in the study. All patients underwent estimation of thyroid function parameters such as triiodothyronine (T3), thyroxine (T4), and ThyroidStimulating Hormone (TSH), as well as anti-TPO levels and selected lipid profile parameters such as Total Cholesterol (TC), Triglycerides (TG), High-Density Lipoproteins (HDL), and LowDensity Lipoproteins (LDL). The association between anti-TPO and lipid levels was further analysed. Statistical analysis was performed using the Chi-square test. Results: Among the 103 hypothyroid patients, 83 (80.6%) were females, while only 20 (19.4%) were males. Positive serum antiTPO antibodies were found in 79 (76.7%) patients, whereas negative Anti-TPO cases accounted for 24 (23.3%). The total serum cholesterol, with a mean of 226.88±37.44 mg/dL, and serum LDL, with 145.31±34.60 mg/dL, were significantly increased (p-value<0.01), whereas the serum TG with a mean of 181.06±52.13 mg/dL, and serum HDL, with 44.61±7.87 mg/ dL, were found to be non significant (p-value>0.05). Conclusion: Hypothyroid patients positive for anti-TPO antibodies are at risk of experiencing disrupted lipid levels. There was a significant association between positive anti-TPO status and TC and LDL in the present study.

An investigation was carried out to estimate genetic parameters, assess association and path coefficient analysis among growth, yield and yield attributes in Multiparent Advanced Generation Intercross (MAGIC) lines of Rice (Oryza sativa L.). A total of 100 MAGIC lines along with seven checks were evaluated in augmented design during summer 2022 at ZAHRS, KSNUAHS, Shivamogga. Analysis of variance revealed significant differences among the advanced lines for all the traits under study. The variability studies among the lines revealed a higher Genotypic Coefficient of Variation (GCV), Phenotypic Coefficient of Variation (PCV), heritability and Genetic Advance as Percent of Mean (GAM) for majority of traits. The correlation and path coefficient analysis revealed that traits tillers per plant, productive tillers per plant, panicle length, number of spikelets per panicle, number of filled grains per panicle, spikelet fertility, test weight and length/breadth ratio were positively associated with yield. Selection of lines with higher filled grains per panicle would be effective for yield improvement program along with the higher percentages of productive tillers per plant, panicle length and spikelet fertility.

Onion (Allium cepa L.) belongs to the family Amaryllidaceae. It is known as common onion, bulb onion or biennial herb, and is one of the most important vegetable crops in India. However, the crop faces numerous diseases attack, resulting in losses to both quantity and quality. Among the diseases, the basal rot caused by Fusarium oxysporum f. sp. cepae, is one of the most significant soil-borne diseases. This work aimed to screen various onion varieties for resistance against basal rot in pots under glasshouse condition as well as to assess the efficacy of fungicides against the pathogen under both in vitro and in vivo conditions. It was observed that all onion varieties screened were highly susceptible while Bhima red was just susceptible; none of the varieties were resistant to basal rot. Under in vitro conditions the Fungicides Carbendazim and Tebuconazole, of the given concentration, were cent per cent effective in inhibiting mycelial growth of Fusarium oxysporum f. sp. cepae. For the field condition, the module of [carbendazim (2 g/kg) followed by tebuconazole (0.1 %) followed by azoxystrobin (0.1 %)] was the most effective.

Published: December 2023

Physical properties of seeds such as size, shape, bulk density, angle of repose and thousand seed mass are important design parameters for seed metering mechanism. Some of the physical properties of maize and pigeonpea seeds were determined as they are crucial factor for effective planting. The average values of length, width, thickness, geometric mean diameter, sphericity, bulk density, angle of repose and thousand seed mass of maize were found as 9.79 ± 0.33 mm, 8.03 ± 0.39 mm, 4.16 ± 0.32 mm, 6.89 ± 0.26 mm, 0.70 ± 0.03, 0.76 ± 0.01 g/cm3, 26.54° ± 0.60 and 223.91 ± 1.50 g respectively at moisture content of 10.90  ± 0.03% on dry basis while similar values for pigeonpea were 6.94 ± 0.31 mm, 5.61 ± 0.30 mm, 4.99 ± 0.27 mm, 5.79 ± 0.19 mm, 0.82 ± 0.03, 0.82 ± 0.01 g/cm3,  28.36° ± 0.44 and 136.64 ± 1.56 g respectively at moisture content of 11.24  ± 0.04% on dry basis. The determined properties were found relevant to the design of the components of planter. The size of cell and delivery tube were relevant to linear dimensions while bulk density and angle of repose were relevant to hopper design.

Data confidentiality implies that data access is limited to authorized entities only, thus measured data and transmitted data by wireless sensors require optimum security and privacy. Various techniques have been employed to implement effective security mechanisms for a wireless sensor network. However, the arsenal of these potential solutions is useless, considering the constrained nature of the Wireless Sensor Network (WSN) resources in terms of memory, processing and computational capacity. While considering an effective solution for this situation, care must be taken not to trade the desired solution for other factors. This paper considers the implementation of a probabilistic approach for key management in WSN. In the implementation, all kinds of communication within the wireless sensor nodes are presented by forwarding encrypted keys for mutual authentication. A successful authentication opens a communication channel for the communicating nodes. The encrypted keys are computed by generating a polynomial which constitutes the hashed ID concatenated with the master key and Message Authentication Code (MAC) address of the node. The results presented from the simulation of this model are benchmarked with the Dynamically Generated Polynomial (DGP). The proposed model was simulated using MATLAB tools and the comparison of the results obtained shows that the proposed model outperforms the DGP model by 87%, based on the key metrics which are energy consumption, storage and communication overhead.

Objective: To assess the incidence of the associated meniscal ligament (ML) with the anterior cruciate ligament (ACL) tears in hospital A in Medina-KSA. And to see the effect of sports activities in comparison between males and females. 

Materials and Methods: In a retrospective study, ninety-nine patients' knee magnetic resonance imaging (MRI) records were selected conveniently from the (A) hospital's picture archiving and communication system (PACS). Patients with suspected anterior cruciate and meniscal ligament' tears were included. Patients with posterior cruciate ligament (PCL) tear, medial collateral ligament (MCL) or lateral collateral ligament (LCL) injury, and previously operated index knees were excluded. All patients were scanned by a 1.5T MRI machine using standard MRI knee scanning protocol. The categorical and continuous variables were presented as percentages, frequencies, and descriptive statistics. The cross-tabulations and chi-square test were applied to obtain the statistical associations between the study variables. A statistical association was considered significant if the P-value was < 0.05. 

Results: 72 males and 27 females were included, with a mean age of 33 ± 2.43. 42.4% of the knee tears were ML tears, followed by associated (ACL with ML) tears, noted in 31.3%, and 26.3% were ACL tears. The tears were more frequent in the age group (31-40), reported in 35.3% (out of 99). There was no statistical association between the tears and the participants' age, gender, or sports activities; P value = 0.3, 0.5, and 0.9, respectively. 

Conclusion: The study concluded that the isolated ML tears were more frequent than the associated (ACL with ML) tears—moreover, there was no significant statistical association between the participants' age, gender, or sports activities.
Mechanical Properties of Window Frames Exposed to High Temperature (II)
Authors: Lee Byeong-Heun
Published: December 2023

This study compares the dropout time obtained through a thermal analysis program with the results of a real experiment to estimate the time when a window in contact with outside air is dropped because of a fire in the compartment space. Nonlinear analysis of PVC and Al6063-T5 window frames on glass with a fire resistance of 1 h showed that the maximum strain over time was approximately 11.04% for the PVC frames and 9.55% for the Al6063-T5 frames. By comparing this over time, it was calculated that the front end occurred at approximately 750 s for the PVC frame and at 1,710 s for the Al6063-T5 frame. Existing real-world experiments show that the frame was deformed by melting and harmful penetration at approximately 540 s for PVC and 1,560 s for Al6063-T5; similar results are expected if the experiment is conducted until the window completely collapses.
Analysis of Spatial Clustering Patterns of Fire Misidentification Through Spatial Autocorrelation Analysis: Focusing on Gyeongsangbuk-do
Authors: Lee Semyeoung
Published: December 2023

In fire departments with a high number of false fire dispatches, firefighters’ work stress is expected to be high because of excessive dispatch work. Therefore, after analyzing the spatial clustering pattern of the study area, we examined whether the opening and deployment of fire departments in the area was efficient and appropriate. Global Moran’s I analysis confirmed that there was spatial autocorrelation between the Gyeongsangbuk-do regions. Through local Moran’s I and hotspot (Getis-Ord’s Gi*) analysis, regions with high and low frequencies of fire misreporting were derived. Examination of the opening and deployment of firefighters in the region suggested that regions with a high average number of dispatches to the 119 Safety Center need to increase the number of firefighters, and that regions where the 119 Safety Center is concentrated should prepare measures to disperse firefighting forces to the surrounding regions.
Possibility of Fire Spreading Owing to Radiant Heat from Fire Shutters in Logistics Facilities
Authors: Seo Heewon , Lee Sangbum , Kim Daehoi , Lee Gilyong
Published: December 2023

The mock-up experiments were conducted to confirm the possibility of fire spreading, such as ignition of commodities (e.g., cardboard boxes), owing to the radiant heat, in the event of a fire in the fire shutter, which is the main fire compartment element that forms the fire compartment of logistics facilities. From the experiment, it was found that commodities located at a distance of 1, 2, and 3 m from the fire shutter can be ignited by the radiant heat of the fire shutter in the event of a fire, which can affect the spread of the fire. Therefore, to prevent the spread of the fire to neighboring fire compartments in the event of a fire in logistics facilities, it is necessary to restrict the placement of commodities within a certain separation distance from the fire shutter or install a fire shutter with radiant heat limiting performance. It is important to improve standards related to fire shutters in logistics facilities.
Design Prediction Equation for Plant Facilities: A Study Using the Pool Fire Radiant Heat Flux Estimation Method
Authors: Lee Byeong-Heun , Park Dong-In , Ahn Chan-Sol
Published: December 2023

This study derived a range of results based on all variables corresponding to a prediction formula for wind and wind-free conditions proposed by fire dynamics tools (FDTs), to estimate the radiant heat flux generated by pool fires. A method using standard deviation was employed to enable a design based on a designer's judgment. A value reflecting a standard deviation of 0.85 times the average value of the regression equation was proposed as a design prediction equation. This proposal was validated through calculations comparing the results with that of a large-scale pool fire experiment presented in the existing literature, to examine the applicability of the equation.

Published: December 2023

In recent times, the strengthening of government safety regulations, such as the implementation of the Serious Accidents Punishment Act, has not succeeded in reducing industrial accidents at small and medium-sized worksites, specifically in the construction sector. The comprehensive amendment of the 2020 Industrial Safety and Health Act brought about considerable changes after 30 years, thereby impacting the safety measures of construction sites. Although the implementation of construction accident prevention technology guidance is mandated, it has not been effectively and practically applied. This study used the analytic hierarchy process analysis, considering quantitative and qualitative aspects, to recommend important factors for enhancing the construction accident prevention technology guidance system. It aims to improve safety management at small and medium-sized construction sites by emphasizing institutional, economic, company-specific, and facility-related factors. The findings of this study can help evolve strategies to improve the construction disaster prevention technology guidance system by providing essential insights and effective requirements that need to be prioritized.
A Study on the Statistical Analysis and Artificial Intelligence Model to Improve the Reliability of Safety Inspection
Authors: Lee Sung Jong , Lee Joo Ha
Published: December 2023

In this study, safety diagnosis results from underground and nuclear power plant structures were collected to evaluate the reliability of on-site structural safety assessments. The analysis of these results revealed a discrepancy between the compressive strength determined by rebound hardness and the core compressive strength, with the former typically being evaluated higher than the latter. Additionally, existing strength prediction models did not adequately explain field data, whereas artificial intelligence models, particularly the support vector machine model, demonstrated improved accuracy and reduced error rates. This indicated the superior performance of support vector machine models in this context.

Published: December 2023

This study investigated the design methodologies outlined in Korean and Japanese legislation, along with Japanese design guidelines, pertaining to natural smoke ventilation systems in logistics warehouses. Subsequently, we determined the effective area of the smoke exhaust system based on the combustible materials and building characteristics. Our findings indicated that the calculated effective area per the statutory standards of both nations was 10 m2 and 20 m2, respectively. According to Japanese guidelines, the space accommodating the CUP ranged from 24.71 m2 to 13.76 m2 for floor heights between 7 to 16 m, while the space accommodating CEP ranged from 41.83 m2 to 22.54 m2. Analyzing the quantity of smoke emitted through the calculated effective area, we observed that, when applying domestic legal standards, the smoke exhaust rate consistently remained lower than the plume flow rate. Conversely, under the Japanese standard, the smoke emission efficiency of the CUP loading warehouse surpassed that of smoke emission from 9 m to 16 m, while it was lower from 7 m to 8 m. Notably, the smoke exhaust rate consistently exceeded the generated smoke quantity in all instances within the effective area governed by the guidelines.
