Quantitative Evaluation Method and Response Mechanism of Shallow Groundwater in Multi-Mine Mining of “Soil–Rock” Composite Water-Resisting Strata
Authors: Zhang Shuai , Zhang Dongsheng , Zhang Yujiang , Feng Guorui , Cui Bingyuan
Published: February 2024

The sustainability of shallow groundwater systems, pivotal to maintaining ecosystem equilibrium and facilitating the sustainable development of mine sites, is the core of various dynamic indicators in response to mining activity and mining area planning. This study quantitatively evaluates the impact of mining activities on shallow groundwater systems at the orefield scale, taking the equivalent permeability coefficient (EPC) of “Soil–Rock” composite water-resisting strata and the response mechanism of shallow groundwater in multi-mine mining as the entry points. A modified six-step evaluation method for the response mechanism of shallow groundwater in multi-mine mining is proposed using mathematical statistics, numerical simulation, and theoretical analysis methods. The method is used to evaluate the sustainability of the shallow water system in the Yushen mining area, to study the distribution characteristics of the water resource carrying capacity (WRCC) in different mining areas of the Yushen area, and to analyze the number of mines allowed to be mined under geological conditions with a WRCC of more than moderate bearing capacity. The results show that when the mining area of a mine in the Yushen area is set to 1 × 108, 7.5 × 107, 5 × 107, and 2.5 × 107 m2, as the mining area of the designed mine decreases, the area bearing surplus gradually increases, with values of 1.70 × 109, 1.98 × 109, 2.28 × 109, and 2.58 × 109 m2. The number of mines allowed to be mined under geological conditions with a WRCC above moderate capacity is 20, 31, 51, and 112, respectively.

Published: February 2024

Purpose: Despite advances in neoadjuvant chemoradiotherapy and anal sphincter-preserving surgery for rectal cancer, bowel dysfunction is still unavoidable and negatively affects patients’ quality of life. In this longitudinal study, we aimed to investigate the changes in bowel function with follow-up time and the effect of neoadjuvant chemoradiotherapy on bowel function following low anterior resection for rectal cancer.Methods: In this study, 171 patients with upper or middle rectal cancer who underwent low anterior resection between 2012 and 2018 were included. Bowel function was assessed longitudinally with Memorial Sloan Kettering Cancer Center Bowel Function Instrument and Wexner scores every 6 months after restoration of bowel continuity. Patients with at least 2 follow-up visits were included.Results: Overall, 100 patients received neoadjuvant chemoradiotherapy. Urgency, soilage, and fecal incontinence were noted within 24 months in the patients treated with neoadjuvant chemoradiotherapy. After 2 years of follow-up, significant bowel dysfunction and fecal incontinence were observed in the neoadjuvant chemoradiotherapy group. Low tumor level and neoadjuvant chemoradiotherapy were associated with delayed bowel dysfunction.Conclusion: Neoadjuvant chemoradiotherapy in combination with low tumor level was significantly associated with delayed bowel dysfunction even after 2 years of follow-up. Therefore, careful selection and discussion with patients are paramount.

Published: February 2024

Purpose: The integration of artificial intelligence (AI) and magnetic resonance imaging in rectal cancer has the potential to enhance diagnostic accuracy by identifying subtle patterns and aiding tumor delineation and lymph node assessment. According to our systematic review focusing on convolutional neural networks, AI-driven tumor staging and the prediction of treatment response facilitate tailored treat­ment strategies for patients with rectal cancer. Methods: This paper summarizes the current landscape of AI in the imaging field of rectal cancer, emphasizing the performance reporting design based on the quality of the dataset, model performance, and external validation. Results: AI-driven tumor segmentation has demonstrated promising results using various convolutional neural network models. AI-based predictions of staging and treatment response have exhibited potential as auxiliary tools for personalized treatment strategies. Some studies have indicated superior performance than conventional models in predicting microsatellite instability and KRAS status, offer­ing noninvasive and cost-effective alternatives for identifying genetic mutations. Conclusion: Image-based AI studies for rectal can­cer have shown acceptable diagnostic performance but face several challenges, including limited dataset sizes with standardized data, the need for multicenter studies, and the absence of oncologic relevance and external validation for clinical implantation. Overcoming these pitfalls and hurdles is essential for the feasible integration of AI models in clinical settings for rectal cancer, warranting further research.
Relativistic Exploration of Dark Matter Effectsin Rotating Galaxy, Studied Fluid-Dynamically
Authors: Kambe Tsutomu
Published: February 2024

Galactic space is filled with interstellar clouds of neutral gases. Motion of the space-clouds is viewed as a flow of continuous fluid in curved space with gravity. Dynamical motions of the space-fluid of rotating galaxies are investigated by extending Fluid Dynamics to that in the frame of general relativity. Fluid flow field to be extended to that of a relativistic theory is reinforced by the fluid gauge theory equipped with a background (dark) gauge field conditioning the fluid continuity. The Gravity-space Fluid Dynamics thus developed captures main feature of the dark-matter effect as the action of the gauge field on the motion of space fluids. In the present formulation, the stress-energy tensor in the general relativity is revised in order to take account of general nature of stress field by extending the isotropic pressure to an-isotropic stress field.

Sistemi informativi dinamici a supporto della documentazione archeologica per interventi in emergenza
Authors: Parrinello Sandro , Porcheddu Giulia
Published: February 2024

This paper analyses data archiving procedures carried out during emergency archaeological excavations. It proposes a model for developing an information system capable of streamlining both the survey practices and the management of the excavation site. The opportunity to digitally acquire what emerged during an archaeological campaign as well as ordering data stemming from the stratigraphic analysis in a single digital database has offered us the possibility to discuss the cataloguing systems used in emergency situations. This drove us to experiment with novel application protocols for digitally recording archaeological evidence. The aim of this research is to reduce the loss of information and create dynamic archives for knowledge. Archaeologists can fill in this digital result with their considerations and hypotheses, as well as creating a study platform directly accessible during the phase of excavation, thus combining 3D digital surveys with archiving systems.
Rilievo per il restauro. La documentazione morfometrica e cromatica della Facultad de Arte Teatral dell’ISA (L’Avana - Cuba).
Authors: Lavoratti Gaia
Published: February 2024

The paper, through the analysis of the case study relating to the morphometric and chromatic documentation of the Facultad de Arte Teatral of the ISA (La Habana), aims to highlight the essential role that the survey of architecture plays in the process of enhancement and protection of Cultural Heritage. The survey is the critical investigation tool by definition: when it’s understood in the broadest sense of the term, it constitutes the necessary cognitive premise at the basis of any design action. This is even more true when the intervention involves the restoration of a cultural artefact aimed at its conservation and management, an operation that assumes a careful analysis of the existing state and the correct reading of the architectural organism in all its parts.

The international cooperation project between Italy and Cuba, ¡Que no baje el telón! is aimed at the restoration and functional recovery of the Facultad de Arte Teatral of the Universidad de las Artes in La Havana (Cuba). The project has made possible to address the delicate issue of relationship between the work of the conservator, the will of the author of the work and the artefact itself. Despite the existence of specific provisions of the law, the formal protection of modern and contemporary architecture (in the absence or in the presence of restrictions) is a delicate operation. Those people called to intervene must have the capability to manage an articulated set of premises, from the state of conservation of the building to the needs of the community that uses it.

The Significance of Ijaw Linguistic Features in Ebi Yeibo's The Fourth Masquerade
Authors: Udisi Arnold Stanley
Published: February 2024

Stylistics is a branch of linguistic studies, which uses the linguistic features in analysing literary texts and other works of art. Stylistics is also seen as the academic study of styles, where a scholar can look at the language and style of any author he chooses to study. This research work looks at the Ijaw linguistic features Ebi Yeibo employs in The Fourth Masquerade to send his intended messages to his readers. The work's title is The Significance of the Ijaw Linguistic Features in Ebi Yeibo's The Fourth Masquerade. The Ijaw linguistic features are identified and interpreted to the readers. The theoretical frameworks chosen as guides to the study are: Leo Spitzer's Philological Circle and Geoffrey N. Leech's Style as Deviation models. The study adopts the Qualitative Approach as the methodology because it is interpretative, descriptive, analytic and evaluative in nature. The aim of the study is to project the fact that code-mixing and code- switching are veritable linguistic tools in a language contact situation. The data of the study is collected through primary and secondary sources, which include: the careful reading of the primary texts, excerpts from a personal interview with the author, and comments from other critics. The work is significant to both researchers, scholars, critics and the society in general because it reveals that an analysis of a literary text from a linguistic standpoint is possible. The study explicates that Yeibo uses lexical borrowings, Ijaw idioms/proverbs, native rhetorical patterns, semantic extension and dislocation, etc. to address the themes of corruption, oppression, poverty, protest, bureaucratic inefficiency of government and institutional and moral decay of the Niger Delta.

Identidade cultural e emigração: Origens de festividades religiosas da diáspora açoriana
Authors: Serpa Silva Susana
Published: February 2024

Descobertas pelos portugueses, no século XV, as Ilhas dos Açores, em pleno Atlântico Norte, acolheram sociedades que perpetuaram costumes, tradições e festividades introduzidas pelos povoadores. Não obstante, as condicionantes inerentes à história e à geografia contribuíram para a implementação de algumas especificidades, por vezes distintas de ilha para a ilha. Sendo o arquipélago uma placa giratória de mobilidade humana, não só foi povoado por reinóis e outros europeus, como foi ponto de partida de muitos fluxos emigratórios com destino ao Novo Mundo (as Américas). Assim, além dos poucos objetos pessoais, estes emigrantes levavam na bagagem, para os territórios de acolhimento, como o Brasil e, mais tarde, os EUA, manifestações da sua religiosidade e das suas vivências do quotidiano, ou seja, marcantes traços da sua identidade cultural que se foi consolidando e persistindo, até aos nossos dias, entre as comunidades da diáspora açoriana e os seus descendentes. A nossa abordagem procura explicar as origens de uma das mais relevantes manifestações identitárias açorianas entre as comunidades de emigrantes — as Festas em honra do Espírito Santo — partindo das práticas do presente, e antes disso, do conceito de identidade cultural, em particular associada às ilhas dos Açores.

Patrząc na Buczę. Badacz Zagłady wobec wizualnych świadectw współczesnego ludobójstwa
Authors: Leociak Jacek
Published: February 2024

Masakra cywilów, jakiej dopuścili się Rosjanie w Buczy, jest punktem wyjścia do rozważań na temat tekstowych i wizualnych świadectw zbiorowej przemocy, aktów ludobójstwa, a przede wszystkim Zagłady. Namysłowi poddane zostały wybrane przykłady przemocy indywidualnej i działań eksterminacyjnych mających miejsce w różnych uwarunkowaniach historycznych i politycznych (od zbrodni na jeńcach podczas wojny secesyjnej, linczu, Holokaustu, wojny w Syrii i rosyjskich zbrodni wojennych popełnianych w Ukrainie). Zróżnicowaniu kontekstu historyczno-politycznego towarzyszy różnorodność mediów komunikacyjnych służących do zapisu i przekazania doświadczeń granicznych, które stały się udziałem ofiar: od świadectw pisanych po blogi internetowe i wpisy na Facebooku, od rycin i zdjęć publikowanych w prasie, po profesjonalne filmy dokumentalne wyświetlane w salach sądowych podczas procesów zbrodniarzy i w salach kinowych podczas specjalnych projekcji, a także prywatne zdjęcia i filmy robione telefonami komórkowymi i umieszczane w internecie. Przy zmienności realiów historycznych i mediów pozostaje jednak niezmienny rdzeń tego typu świadectw: po pierwsze nieodparta potrzeba, wręcz nakaz ich sporządzania, po drugie — fundamentalne podobieństwo, czyli wspólne dla wszystkich tych świadectw fundament: śmiertelny lęk, przerażenie, groza, poczucie bezbronności i opuszczenia. Autor skupia się przede wszystkim nad charakterem przekazu wizualnego, fenomenem fotografii okrucieństwa i przemocy, oraz ich oddziaływania na odbiorcę.

Məqalədə neft boru kəmərinin fəaliyyətinin səmərəliliyinə təsir edən amillərin kompleks səciyyəsi açıqlanmış və bu prosesin idarə edilməsinin bəzi metodoloji xüsusiyyət daşıyan mövcud məsələləri, eləcə də neftin nəqli prosesinin bəzi kəmiyyət göstəricilərinin qiymətləndirilmə düsturları şərh edilmişdir.
Neftin nəqli prosesinin məhsuldarlığı isə bir sıra kompleks xarakterli amillərlə səciyyələnir ki, bunlardan ən mühümü neft kəməri avadanlıqlarının parametrləri ilə əlaqədardır. Təhlil edilmiş texniki göstəricilər əsasında əməliyyat parametrlərini dinamik şəkildə tənzimləyən əks əlaqə nəzarət sistemlərini əhatə edən səylər sadəcə performans göstəricilərindən kənara çıxır. Bu sistemlər mühərrikin müxtəlif şəraitdə optimal işləməsini təmin edir. Bundan əlavə, optimallaşdırma strategiyaları həm iqtisadi, həm də ekoloji dayanıqlığa töhfə verərək, enerji istehsalı, yanacaq sərfiyyatı və emissiyalar arasında tarazlıq yaratmağı hədəfləyir.
Texniki göstəricilərin müəyyən edilməsi və modelləşdirilməsi təkcə mühərrikin cari performansını nəzərə alaraq deyil, həm də gələcək çətinlikləri proqnozlaşdıraraq mühərrikin idarə edilməsinə proaktiv və səmərəli yanaşmanı təşviq edən kompleks yanaşma formalaşdırır.
Neft kəməri avadanlıqlarının parametrlərinin onun daşınması prosesinin məhsuldarlığına və elektrik enerjisindən istifadənin səmərəliliyinə təsirinin qiymətləndirilməsinin aktuallığı, başlıca olaraq, daşınan neft həcmlərində illik stabillik və artıma, eləcə də xüsusi elektrik sərfiyyatının azaldılmasına olan ehtiyacın olması kimi iki əsas amillə izah olunur. Bildiyiniz kimi, hər hansı bir texnoloji prosesin məhsuldarlığı və səmərəliliyi istifadə olunan avadanlıqların parametrləri və istifadə olunan xammal və digər mənbələrin keyfiyyəti ilə müəyyən edilir. Ona görə də neftin daşınması prosesinin kompleks səmərəliliyinin müəyyən edilməsinin də bu amillərin nəzərə alınması çərçivəsində aparılması məqsədəuyğun hesab edilir.

Published: February 2024

Using a variational method within the framework of an effective mass approximation, applying a triangular coordinate system of an electron, a hole and an exciton moving in a titanium dioxide nanocrystal, an exciton energy spectrum was obtained as a function of a radius of the nanocrystal particle. It was established that the optical absorption of anatase nanocrystal, observed in the experiment, was due to the appearance of an exciton in the nanocrystal. Using a variational calculation of the energy spectrum of the exciton in the nanocrystal, a position of an absorption peak was determined.

This experimental quantitative research applied  on-group pretest-posttest design. Based on a sample of 16, the children showed an increase in the average result of pre-test by 18.8, meaning that the child's spatial visual intelligence is in the category of developing. Meanwhile, the data from posttest obtained an average of 32, meaning that the child's spatial visual intelligence is in the category of developing as expected. These results proved that there is a significant effect before and after treatment. Based on the results of the t test on (ɑ) = 0.05 obtained ttable = 0.213 and t count = 20,09, which means tcount  ≥ t table 20.09 ≥ 0.213 and in other words,  H0 is rejected and H1 is accepted. Thus, the research hypothesis states that there is an influence of geometric shape mosaic media on visual-spatial intelligence of the children at TK Teratai Kindergarten in Huangobotu Village, Kabila Bone District, Bone Bolango Regency.

The study deals with the concideration of a range of issues related to the involving additional knowledge about subject domain when solving machine learning problems. The techniques for accounting such knowlwdge based on the modification of classical methods of classification, clustering, associative rule discovery are described. It is concluded that the analysis of bachgroung knowledge is able to increase reliability and accuracy of classical machine learning methods, although their modification, taking into account additional constraints, sometimes turns out to be a rather time-consuming procedure. In addition, different types of machine learning problems require different types of additional constraints to increase the reliability and accuracy of their results. This provides certaint difficulties in solving complex problems that require gradual involvement of various types of additional constraints.

The relationship between technology and education has been going on for quite a long time. The use of information and communication technology for learning is increasingly developing. With the idea of ​​developing the internet of things (IoT), the use of technology for learning is increasingly showing significant progress. As a consequence, life activities are very dependent on the Internet, one of which is carrying out the education process. Considering the enormous potential for development of Internet of Things (IoT) technology, knowledge about this technology and how to use it in everyday life is very necessary. SMAN 1 Kepahyang has development potential in utilizing IoT technology, but requires training in its use in education.

Published: February 2024

Interest in mental disease is increasing. Recently a positive association between elevated temperature and mental disease has been reported. However, there was a limitation in that detailed interaction with age could not be confirmed. In this study, to overcome such limitations, the association between emergency room visits due to mental disease and mean temperature was explored by using the age-specific distributed lag model. The age-specific distributed lag model is a model in which a coefficient of age and lagged temperature are integrated into the existing distributed lag model. Accordingly the dimension of the parameter space was reduced by expressing the increased parameters as a linear combination of prediction process basis functions and the accuracy of parameter estimation was increased using information on the total age. The degree of borrowing information over age was estimated through variogram modeling. From 2014 to 2020, 906,958 patients visited the emergency room due to mental disease in Seoul. The age groups with a positive cumulative association over the lag period of 0-3 days between mean temperature and emergency room visits due to mental disease were 15 to 24, 40 to 59 and 80 to 84. As the effects of climate change become a reality, understanding detailed vulnerabilities will become very important for public health planning and intervention.

The art market is comprised of complex cultural, economic, and social characteristics and has recently received a lot of attention. Art transactions are carried out in a variety of ways, of which art auctions account for a large portion. We collected auction data on Post-War and Contemporary Art artists born after 1920 from Artnet and implemented an art price prediction model. In addition to the hedonic price model commonly used in existing studies, price prediction performance was compared using various machine learning models such as regression model, random effects model, regularization model, tree-based model, and SVM. To compare various machine learning models, RMSE and MAE were compared using two cross-validation methods. As a result, the nonlinear random effects model using author information showed the good performance. The impact of explanatory variables on price was analyzed using the optimal model. In addition, we were able to obtain price curves of various patterns according to the passage of time for each author. Among machine learning models that do not use author information, Bagging showed the best performance. As a result of measuring the importance of variables through Bagging, it was found that the size of the work had the most influence in predicting the price, followed by the artist's year of birth, the method of painting, the material with which the painting was painted, and the year of production.
A Study on Computing Sample Quantiles of Discrete Probability Distributions
Authors:   The Korean Data Analysis Society, Kim Hyuk Joo
Published: February 2024

In this paper, we studied the methods of computing sample quantiles for the case of discrete probability distributions. There are two main methods which are introduced in statistics textbooks. We compared these two methods by simulation from practical and educational necessity. We considered some cases of Poisson, binomial, geometric, negative binomial, and discrete uniform distributions by setting up the parameters, and for each distribution we performed 10,000 times of simulation of drawing random samples of size 20 and 50. At each time of simulation, we computed the difference between the population quantile and the sample quantile obtained by each method. We compared the two methods by using two criteria: one is the mean square error over 10,000 times of simulation, and the other is the frequency of obtaining closer sample quantile to the population quantile than the competing method. We also obtained the estimated probabilities of exact estimation of population quantiles for the two methods, and performed the tests of homogeneity on the probability distribution of under-estimation, exact estimation, and over-estimation of the population quantiles.
An analysis of employment insurance blind spots and uninsured characteristics
Authors:   The Korean Data Analysis Society, Chae Subok , Kwon Taegoo
Published: February 2024

The study aims to analyze the uninsured characteristics and blind spots of employment insurnce. Specifically, it analyzed the dynamic trends of the blind spot, and attempted to clarify the explanatory power of job characteristics in addition to the characteristics of the workplace and the individual as the cause of uninsured. Empirical analysis is carried out with Supplementary surveys of the Economically Active Population Survey by Employment Type microdata between 2011 and 2022. Empirical results indicate that the employment insurance blind spot has been steadily decreasing in the past 11 years, but the size of blind spots in small businesses with less than 5 employees and low-wage workers is still large. As the result of the regression through the linear probability model, the scale of the workplace and the wage gap significantly explain non-coverage, but the explanatory power of the occupational status is much higher. In other words, it is more closely related to the characteristics of workers within the business, such as occupational status and the application of personnel management regulations, rather than the scale of the workplace. These results suggest that efforts to resolve actual blind spots can be a means of alleviating actual blind spots in addition to providing subsidies, by considering the existence of personnel regulations and the reasons for the uninsured. However, these findings have the limitation that it is only a description of high correlation, not a causal relationship.
