Authors: Zhu Lihua
Published: July 2024

In the information network, using the characteristics of information diffusion of the Internet, information pushing can be carried out effectively to help publicize safety education, which is of great significance to the construction of safety education system in colleges and universities. In this paper, we optimize the distribution of nodes through graph transformation and independent set ideas and propose an influence maximization algorithm based on HISS to improve the usability of safety information. On this basis, an adaptive safety education system is designed, and an optimization algorithm is proposed for determining the probability of content and knowledge point mastery, which is applied to actual safety education. It was found that the total score of the safety test of the experimental class was improved by 16.22 points before and after, the total score of the experimental class exceeded that of the control class by 10.49 points, and the p-values were all less than 0.001. In total, 84.53% of the students strongly agreed or agreed that the types of learning resources could satisfy their learning needs, and 82.29% of the students were satisfied or very satisfied with the way of pushing the resources of the online course. It indicates that improving the safety education system can increase students’ motivation to learn safety, promote the mastery of safety skills, and cultivate safety awareness.
Comparison of Chinese and Foreign Communication of “Community of Human Destiny” Identity: A Corpus-Based Analysis
Authors: Zu Yanfeng , Chen Xiuchun , Liu Yi
Published: July 2024

Since the concept of “Community of Human Destiny” was proposed in 2012, it has garnered extensive attention from British, American, and other Western media. In this paper, a comparable corpus is constructed with the reports on “Community of Human Destiny” and related news articles in Chinese and Western mainstream media. Using the AntConc search tool, the CRF-NLG model embedded in natural language grammar is established by using corpus-based discourse analysis combined with Lafferty’s Conditional Random Field Model to realize the identification of terminology and the extraction of the corpus. The Chinese and Western media coverage corpora CSFCNC and CSFWNC are constructed to explore the differences in Chinese and Western mainstream media’s image construction of China. The results show that “Benefit” appears most frequently in overseas media’s publicity of the “Community of Human Destiny” (Frequency=521, LLR=6.37), indicating that the overseas media’s publicity of the “Community of Human Destiny” has a strong influence on China’s image. This shows that the determining factor of the judgment standard and attitude of overseas media towards the “Community of Human Destiny” is “self-interest”. The Chinese media’s coverage of the “community of human destiny” has constructed the image of China as a responsible socialist power that promotes common development and seeks the well-being of all peoples. This kind of research has important reference value for how to further develop multilevel and multi-disciplinary public diplomacy and international political communication, better shape China’s national image, and enhance national soft power and global discourse.

Authors: Sun Yuhang
Published: July 2024

Physical education teaching in colleges and universities faces the problems of lack of attraction, no daily exercise supervision, and teachers cannot accurately grasp the exercise intensity of each student. In this paper, in order to innovate the sports teaching mode in colleges and universities, a sports monitoring system in colleges and universities is designed, which firstly expresses and calculates the motion features in space, updates the normalized quaternion, and obtains the real-time posture angle of the human body. The motion feature extraction is carried out to accurately fit the trend of motion state change after Kalman filtering of the state quantity to monitor stationary, running, fast walking, and warm-up motion recognition. The monitoring system that was constructed is utilized in a college sports classroom, and the waveforms of every motion signal measured by the system are examined. The innovative model of college sports was tested in a one-semester teaching experiment. It is found that the system determines that the combined acceleration of a student at rest is 1.005g to 1.03g, the number of times that the combined acceleration peak is greater than 2g and less than 6g when running 28 steps is 28 times, and the combined acceleration of fast walking 12 steps meets the judgment criteria for a total of 12 times, which is in line with the actual state of the system. After one semester of an innovative mode teaching control experiment, the average physical education score of the experimental class increased dramatically from 60.8 points to 78.6 points, an increase of 29.3%. This study provides a useful exploration of the innovation of physical education teaching methods in colleges and universities, taking into account the integration of big data and information technology in physical education.
Deep Learning-based Basketball Free Throw Attitude Analysis and Hit Probability Prediction System Research
Authors: Zhao Bo
Published: July 2024

Traditional basketball free-throw hitting probability prediction mainly relies on naked eye vision to analyze basketball players, which makes it difficult to achieve stable and accurate free-throw hitting probability prediction. In this study, we propose a deep learning-based algorithm for recognizing basketball free throw poses and predicting the probability of hitting free throws, and we build a corresponding system framework. DetectNet is used to screen free throw motion detectors, real-time estimate and recognition of free throw poses, and code rewriting. At the same time, Open Pose is used as a human skeletal joint point detector to extract the joint point information of the free throw shooter. The joint points with wrong information are repaired, and the classification prediction of the free throw hitting result is realized based on the support vector machine. In the performance simulation experiments, the average accuracy of the free throw pose recognition method proposed in this paper is as high as 98.55% on the MSR Action 3D dataset, and the recognition rate of the elbow lift pose, which is the most difficult to recognize, is also higher than that of other comparative algorithms. The hit probability prediction method is also 12.64% and 6.25% more accurate than the OpenPose algorithm in hit-and-miss prediction, and the accuracy has also improved by 4.47% and 5.41%, respectively. The free throw pose recognition and hit probability prediction method in this paper has excellent performance.

Authors: Zhang Han , Ping Hongming
Published: July 2024

With the rapid development of science and technology, the traditional construction industry is facing the urgent need for transformation and upgrading, and how to achieve the performance optimization of the assembly building frame has become an urgent problem to be solved. The research constructs the antique assembly building frame using BIM technology and uses a Matlab genetic algorithm to optimize the model of the building frame. The efficacy of the optimized assembly building is analyzed, and the safety performance of the BIM-Matlab frame building proposed in this paper is compared with that of the traditional frame building and the anti-buckling frame building to explore the effectiveness of the performance optimization of the BIM-Matlab frame building. The values of the structural non-lateral stiffness ratio of the BIM-Matlab assembly building are all greater than or equal to 1, and the seismic shear weight ratio meets the requirements. The displacement ratio and inter-story displacement ratio meet the code requirements under all working conditions. The building foundation’s zero stress zone is 0.00%, and the minimum stiffness-to-weight ratio value of 38.69 is enough to pass the overturning resistance and stability test. The BIM-Matlab framed building can endure earthquakes with greater intensity and safety reserves than conventional framed buildings and anti-flexural framed buildings, which are more secure in earthquakes.

Authors: Yin Yimin
Published: July 2024

Establishing a medical archive information resource-sharing platform can effectively address issues of resource waste, unavailability, and retrieval. The article develops a medical archive information resource-sharing platform using virtualization and cloud computing technology and proposes a virtualization-based RA_WLC resource scheduling strategy to achieve real-time allocation and scheduling of system resources. Through experimental testing of the medical archive information resource-sharing platform proposed in this paper, the article concludes that two critical paths to promote the construction of the resource pool are derived from the grouping analysis of conditional variables, i.e., Combined Path I (A1): P1*P2*P3*P4*P5*~P7 (Subject*System Standard*Technology Platform* Resource*User*Non-Feedback), Combined Path II (A2): P1*P2* P3*P4*P5*P6 (subject*system standard*technology platform*resource* user*environment). The performance test of the system yields a fault tolerance rate of 0~0.01 for 2000~4000.

Authors: Ding Jieqin , Hu Dong , Ding Jieqi
Published: July 2024

Conventional human dance posture detection methods have problems such as low motion detection accuracy and recognition rate, so a simplified and improved mayfly algorithm is proposed to optimize the human dance posture detection methods. To begin with, a high-precision Kinect sensor is employed to gather 3D data on human dance posture movements. Then, the movement categories are recognized based on the indirect segmentation principle of the sliding window design. Then, the improved mayfly algorithm optimizes the multi-threshold combination of image segmentation to determine the optimal segmentation threshold. It is proposed to use gesture-based feature description to fully represent the human action information, use human gesture to obtain the human body regions in the frame, extract 3D-SIFT and optical flow features for each region, respectively, and then compare with other intelligent algorithms, and the experimental analysis shows that the proposed method is better than the DSI method in terms of Average accuracy and Accuracy at the worst performance. Performance is higher than the DTW method, with a difference of 29.91% and 28.65%, respectively. The improved mayfly algorithm’s simulation results are more accurate and stable than other methods, which improves the recognition rate and allows for more precise detection of human dance postures.

Published: July 2024

The significance of interactive pedagogy in English education cannot be overstated, as it fosters student engagement, collaboration, and active learning, thereby enhancing both academic performance and comprehensive capabilities. This article presents a structured three-step strategy designed to integrate curriculum thinking into the teaching of English at higher vocational levels through a blended online and offline approach. Central to this methodology is the development of a robust “online + offline” teaching quality evaluation index system, innovatively constructed using a combination of rough set theory and a backpropagation (BP) neural network algorithm. Furthermore, the effectiveness of this pedagogical approach is quantitatively analyzed using a Markov chain model, which evaluates the progression of students’ English proficiency. The analysis reveals that sustained application of the proposed teaching methodology is likely to elevate students’ English performance to an estimated score of 84.273, marking a substantial improvement of 5.443 points over traditional methods. Empirical validation of the model’s effectiveness was achieved through student evaluations across three critical areas: Civic Integration Effectiveness, Pre-Class Preview, and Follow-Up Testing. The results of the post-test assessments yielded mean scores of 3.565, 3.564, and 3.695, respectively, indicating a significant enhancement in learning outcomes, as evidenced by p-values of less than 0.05. This statistical analysis confirms the significant impact of the innovative pedagogical strategy on student learning outcomes.
Exploring the Path of Practical Reform of Art Design Teaching in Higher Vocational Colleges and Universities from the Perspective of Non-Heritage Culture
Authors: Huang Xin
Published: July 2024

This paper uses Python technology and Slope One algorithm to realize a personalized teaching resource-sharing platform for non-heritage cultural learning resources. Intangible cultural heritage is introduced into the art design specialty and then incorporated with digital teaching techniques to propose an innovative approach to the construction of the art design specialty. By collecting relevant information to understand and analyze the current situation of non-heritage and art design professional construction, its characteristics and development trends are summarized. The results show that “non-heritage culture” + “art design” retrieved 184 articles, accounting for 0.25%. The average teaching evaluation is 4.48, which is a high level. Digitalized non-fiction culture is becoming more and more common. The number of teachers in higher vocational colleges who are over 40 years old and have lower education is only 8. In the analysis of the satisfaction survey of the personalized teaching resource-sharing platform, most of the students were satisfied with the updating and pushing of teaching resources, the diversification of the classroom form, and so on, and the interactivity was still lacking. Therefore, in the context of the digitization of non-heritage culture, the method of this paper provides a new path for the construction of the art design profession.
International law framework for the taxation of cross-border transactions in cloud computing services
Authors: Huang Yuxiang
Published: July 2024

Cross-border cloud services are transforming our lifestyles and accelerating the computerization of everyday life. Every day, cross-border cloud services are having an increasing impact on income tax jurisdiction due to their rapid development. The concept of cross-border cloud services is introduced in this paper, and the impact of cloud computing on tax jurisdiction is discussed. In order to measure the scale of corporate income tax loss during cross-border cloud service transactions, this paper constructs a tax revenue capacity measurement integral model and designs a measurement process based on Bayes’ theorem for the measurement of tax loss across time. Finally, combined with the tax revenue capacity measurement integral model, it empirically demonstrates the scale of corporate income tax loss in cross-border cloud service transactions in 20 provinces and municipalities in China from 2021 to 2023. The regions with more tax loss are Beijing (18.74), Guangdong (4.79), Zhejiang (0.82), and Shanghai (0.73), with a total loss of 597 million yuan, 831 million yuan, and 1.061 billion yuan of cross-border cloud service transaction enterprise income tax in the past three years. Based on the statistics on Amazon’s payment of income tax on cross-border cloud service transactions in 2021-2023, it appears that Amazon’s actual tax payment does not correspond with the income tax payable. It shows that the legal lack of income tax jurisdiction during cross-border cloud service transactions exacerbates the amount of tax losses in China. For this reason, this paper constructs an international law framework from two aspects: the type of income from cross-border cloud services and the determination of permanent establishment.

Published: July 2024

Ectoparasites, particularly monogeneans, negatively affect fish health and growth. This study identified monogenean parasites in the twobar seabream, Acanthopagrus bifasciatus (Sparidae), inhabited the Arabian Gulf (Saudi Arabia). Following that, forty A. bifasciatus fish samples were visually examined for monogeneans. Parasite species were collected from the gills and then analyzed morphometrically, morphologically, and molecularly using the partial regions of the large subunit of ribosomal RNA (28S rRNA) and mitochondrial cytochrome C oxidase subunit I (COI) genes. Fish species were also identified using a DNA barcoding approach based on the COI gene. The monogenean species of Diclidophora merlangi (Diclidophoridae) were found in 45% of the fish species studied. The generic features of the Diclidophora genus distinguish this species. This species discriminated itself from congeners by having a muscular bulb with 17 grooved and recurved hooks, 218±10 (184–267) post-ovarian testes, and four pairs of pedunculated clamps of relative sizes. Partial 28S rRNA sequencing from monogeneans revealed that they grouped with members of the genus Diclidophora, forming a monophyletic group that supported the morphological descriptions. Molecular identification revealed that D. merlangi has a unique barcode made up of a COI sequence. The host identity was established as A. bifasciatus based on the COI gene sequences. Furthermore, a molecular phylogenetic study was performed to determine the phylogenetic affinity of parasite species and fish hosts. This study on Diclidophora species is considered the first record of this genus in the examined area.

Published: July 2024

The current study assessed the efficacy of Acyclovir (ACV) and Ivermectin (IVM) as monotherapies and combined treatments for intestinal and muscular stages of Trichinella spiralis infection. One-hundred Swiss albino mice received orally 250 ± 50 infectious larvae and were divided into infected-untreated (Group-1), IVM-treated (Group-2), ACV-treated (Group-3), combined IVM+ACV (Group-4), and healthy controls (Group-5). Each group was subdivided into subgroup-A-enteric phase (10 mice, sacrificed day-7 p.i.) and subgroup-B-muscular phase (10 mice, sacrificed day-35 p.i.). Survival rate and body weight were recorded. Parasite burden and intestinal histopathology were assessed. In addition, immunohistochemical expression of epithelial CDX2 in the intestinal phase and CyclinD1 as well as CD34 in the muscular phase were evaluated. Compared, IVM and ACV monotherapies showed insignificant differences in the amelioration of enteric histopathology, except for lymphocytic counts. In the muscle phase, monotherapies showed variable disruptions in the encapsulated larvae. Compared with monotherapies, the combined treatment performed relatively better improvement of intestinal inflammation and reduction in the enteric and muscular parasite burden. CDX2 and CyclinD1 positively correlated with intestinal inflammation and parasite burden, while CD34 showed a negative correlation. CDX2 positively correlated with CyclinD1. CD34 negatively correlated with CDX2 and CyclinD1. IVM +ACV significantly ameliorated CDX2, CyclinD1, and CD34 expressions compared with monotherapies. Conclusion. T. spiralis infection-associated inflammation induced CDX2 and CyclinD1 expressions, whereas CD34 was reduced. The molecular tumorigenic effect of the nematode remains questionable. Nevertheless, IVM +ACV appeared to be a promising anthelminthic anti-inflammatory combination that, in parallel, rectified CDX2, CyclinD1, and CD34 expressions.

Authors: El-Siefy A. M. , Ibraheem M. H. , Abd El-Kareem S. G.
Published: July 2024

In Acanthocephala, the ovarian balls (floating ovaries) are distinctive structures found suspended in the fluid-filled metasoma of females and are responsible for egg production and maturation. Those structures have not been studied in Rhadinorhynchus niloticus. We aimed to investigate their ultra-structure by means of scanning and transmission electron microscopy. A total of 30 Lates niloticus fish individuals were collected by fishermen from the River Nile, Egypt, and the isolated adult female specimens were processed for electron microscopy studies. The ovarian balls are elongated and lobulated structures freely scattered in the metasoma. They exhibited three distinct primary structural zones, a central oogonial syncytium, a peripheral cellular zone and a surrounding somatic supporting syncytium. The oogonia, within the central syncytium, give rise to developing oocytes that transform into mature oocytes. The latter enclose some inclusions such as large yolk granules and smaller egg-shell granules. We also describe the process of fertilization within the ovarian ball. The structure of the ovarian ball and the steps of fertilization in R. niloticus are described, for the first time, in the present study.

Bertiella spp. is a mite-borne cestode parasite that inhabits the small intestine of wide range of mammals, including non-human primates. In the present study, the morphological and molecular analysis of Bertiella studeri recovered from the small intestine of a bonnet macaque (Macaca radiata) from Wayanad, Kerala (South India) was performed. Acetic alum carmine staining identified the cestode morphologically based on the characters like broader proglottids, which contain irregularly alternating genital pores, single set of reproductive organs, 280 testes and a tubular transverse uterus. Molecular characterization was done using 18SrRNA, ITS1-5.8S and COX1 genes. Phylogenetic trees were constructed using MEGA X based on the Maximum Likelihood (ML) method (Hasegawa-Kishino-Yano (HKY) model). Cytochrome oxidase I gene could detect the existence of genetic variation in the parasite from two different hosts viz., monkey (Kerala, Argentina, and Kenya) and human (Sri Lanka). A minimum spanning network of haplotypes was generated by the haplotype networking with the above sequences using the popARTv1.7. Haplotype analysis based on COX1 revealed that the parasite haplotype was different in each country with highest population frequency in Sri Lanka.

Published: July 2024

Bats are often associated with several zoonotic diseases, including helminth infections. Despite their potential detrimental effects on both human and bat populations, information on helminth parasites of Philippine bats remains scarce. Here, we identify gastrointestinal helminths parasitizing bats collected from a cave complex in Cavinti, Laguna Province, Philippines, determine their prevalence (P) and mean intensity (MI), and investigate relationship of helminth prevalence and intensity with bat host characteristics including sex, diet, age, and roosting habit. We isolated 581 individuals of helminths representing six taxa (three trematodes, two nematodes, one cestode) from the gastrointestinal tract of sampled bats. Helminths were observed in 82 out of 172 bats captured (P = 47.67%), with Miniopterus paululus having the highest infection rate (P = 91.3%) and highest MI (18 ± 4.5/infected bat). Helminths parasitizing endemic bat species from the Philippines, such as Rhinolophus rufus, Rhinolophus inops, Hipposideros pygmaeus, and Ptenochirus jagori were reported here for the first time. We provide new host records for other helminth species and report the presence of two parasites, Plagiorchis sp. and Toxocara sp., known for their zoonotic potential. These data will contribute to efforts in identifying parasites and diseases harbored by bats in the country and develop additional conservation measures for bats.

Studying parasites in captive wild birds is vital for their health, well-being, biodiversity preservation, species conservation, and safeguarding of both individual birds and ecosystems. It holds significance for public health by identifying potential zoonotic risks. We aimed to describe the occurrence of gastrointestinal parasites in captive wild birds from a Conservation Institute in Brazilian Cerrado biome. Fresh fecal samples were collected from 17 captive wild birds (Anodorhynchus hyacinthinus, Ara ararauna, Ara chloropterus, Ara macao, Megascops choliba, Pteroglossus castanotis, Ramphastos dicolorus, Ramphastos tucanus and Strix huhula) at a Conservation Institution in Mineiros, state of Goiás. The samples were processed for Willis’ simple flotation and Hoffman’s spontaneous sedimentation examinations to identify parasitic forms of gastrointestinal endoparasites. Macaw aviary birds (Ar. ararauna, Ar. chloropterus and Ar. macao) showed higher positivity, with all six fecal samples positive for helminths or protozoa. In contrast, captive toucans showed only two positive results (P. castanotis and R. dicolorus). An. hyacinthinus showed Ascarididae, Capillarinae and Trematoda eggs; whereas S. huhula had Ascarididae eggs. Regular parasitological examinations are essential for the timely detection and treatment of gastrointestinal infections in captive birds, thereby enhancing overall bird management.

This research aims to investigate the factors leading to siltation in Lake Limboto by analyzing its morphometric characteristics gathered through direct field measurements and remote sensing using Geographic Information System (GIS). Lake Limboto covers an approximate surface area of 26.09 square kilometers, boasts a maximum depth of 4 meters, and maintains an average depth of 2.83 meters. The Shoreline Development Index (SDI) stands at approximately 2.57, indicating an irregular shape of the lake's water body, while the Lake Volume Development (VD) index, at 2.12, suggests a generally flat lake bottom. The Relative Depth (Zr) registers at around 0.69%, as observed from the water turbidity level. The lakebed relief in the vicinity of the lake's periphery is predominantly flat and shallow, particularly in the western, northern, and southern regions, with depths measuring less than 2 meters. In contrast, the lakebed relief in the central and eastern sections tends to be less flat but still features depths of less than 4 meters. Siltation in Lake Limboto primarily results from high sediment input originating from erosion processes, agricultural activities, and settlements in the surrounding area.

Nutmeg (Myristica fragrans) is spice plant which has an important position as a source of essential oils. An important problem in nutmeg cultivation is white root disease which can reduce nutmeg production. Until now, white root disease is still a problem in nutmeg plantations in South Aceh district. One of the solution that can be explored as an environmentally friendly control measure is to use the botanical fungicide coconut shell liquid smoke. This research aims to determine the potential of coconut shell liquid smoke in controlling white root fungus in vitro. The research was carried out in the Plant Protection Laboratory, Faculty of Agriculture, Teuku Umar University. The research design used was a non-factorial Completely Randomized Design (CRD) consisting of nine levels of liquid smoke concentration treatment; control 0%, 0.5%, 1%, 2%, 3%, 4%, 6%, 8%, 10%. Each treatment involved three replications. Data analysis was carried out using analysis of variance and Tukey's least significant difference (HSD) test.The research stages carried out consisted of producing coconut shell liquid smoke, isolating white root fungus from the roots of infected nutmeg plants and potential assay of liquid smoke in inhibiting the growth of white root fungus. In vitro bioassay result showed that liquid smoke treatment 3% was the best treatment because it was the lowest concentration causing total inhibition of the growth of white root fungus.

Adenostemma lavenia (L.) is one of the medicinal plants on Nias Island that is used to treat many symptoms including cough, fever and diarrhea. Empirical data of this plant suggests that these medicinal benefits can be attributed to its antibacterial and antioxidant properties, as well as the total flavonoids contained within it, but research on this is still limited. Adenostemma lavenia (L.) was extracted with ethanol, while the antibacterial properties were measured using the disc method. Antioxidant testing was conducted with the DPPH (1,1-diphenyl-2-2picrihydrazyl) inhibition method. Total flavonoids were assessed using a modified AlCl3 method with a quercetin standard. Antibacterial test results of Staphylococcus aureus, Klebsiela pneumoniae, Propionibacterium acnes, Escherichia coli, Salmonella typhi, Bacillus cereus and Shigella sonnei with mean inhibition were 8.76 ± 0.44, 8.13 ± 0.72, 8.77 ± 0.45, 6.47 ± 0.54, 7.77 ± 0.60, 7.33 ± 0.44, 12.06 ± 0.60 respectively. IC50 was 59.844 ± 3.36 ppm. Total flavonoids were 13.566 ± 0.021 mcg/g. The results of the antibacterial test of the ethanolic extract of Adenostemma lavenia (L.) were classified as moderate. The antioxidant activity and total flavonoids were in the high category, which can be attributed to the capture of free radicals to overcome disease.

Small area statistics are required when the sample size is small to produce estimates with adequate precision. The assumptions underlying Battese Harter Fuller (BHF) unit-level models may often be unrealistic in some applications. Copula is an alternative approach when the assumptions are violated. This research discusses the performance of BHF and Copula in small area estimation (SAE) for estimating household per capita expenditure in sub-district levels. This study presents household per capita expenditure, which has a skewed distribution. Due to the fact that the data contains outliers, an appropriate method to handle outliers is also considered. In this research, the Gaussian and the Clayton Copulas are used. The results showed that the performance of BHF was better than Gaussian and Clayton Copulas, as indicated by small root mean square error (RMSE) with an average of 1.14, while the average RMSE of Gaussian copula was 2.71 and Clayton copula was 2.63. Furthermore, the coefficient of variation (CV) of BHF was also smaller compared to Gaussian and Clayton Copulas, and the resulting estimates can be categorized as reliable based on the CV of less than 25%.
A case report on pancreatic plasmacytoma presenting as obstructive jaundice
Authors: Tafader Asiya , Nadeem Mahum , Spataro Joseph
Published: July 2024

Background:

Extramedullary solitary plasmacytomas (EMD) are an uncommon manifestation of plasma cell disorders. The median survival rate is less than 6 months. EMD rarely involves the digestive tract, the liver is the most common site with only a 2.3% incidence rate for pancreatic involvement.

Case Presentation:

We report a case of a patient with a history of multiple myeloma who presented with painless obstructive jaundice and EUS findings of hypoechoic, solid irregular mass in the pancreatic head with surrounding peripancreatic lymphadenopathy. Fine needle aspirate (FNA) confirmed malignant infiltration of plasma cell neoplasm. The patient rapidly deteriorated and succumbed to his illness within 6 weeks of diagnosis.

Conclusion:

Extramedullary plasmacytomas (EMD) involving the pancreas are uncommon and associated with a poor prognosis. Our case highlights the importance of considering extramedullary plasmacytoma when a patient with MM presents with a pancreatic mass, particularly one showing a rapid interval growth. This rate of growth is not seen with primary pancreatic parenchymal diseases such as cancer, cysts, and so on. This case highlights the importance of considering rare differentials while evaluating patients with pancreatic mass.

Rare and lethal: a case report on the grim reality of EMD infiltrating the pancreas. Despite its rarity, timely recognition is crucial for improved outcomes in patients with multiple myeloma. #MedTwitter #Oncology #CaseReport”

Penelitian ini bertujuan untuk menjelaskan bagaimana lahirnya strategi baru akibat dari adanya kemajuan tekhnologi serta pengaplikasian dari strategi tersebut. Strategi-strategi yang dulu bersifat klasik kemudian berubah menjadi modern tatkala perkembangan teknologi tersebut semakin meningkat. Perkembangan tersebut kemudian membawa manusia kepada era yang disebut dengan era nuklir sebagai hasil dari kemajuan tekhnologi. Nuklir yang merupakan senjata pemusnah massal pertama kali digunakan pada masa Perang Dunia II ketika Amerika Serikat melakukan penyerangan terhadap Jepang. Besarnya korban jiwa serta dampak yang ditimbulkan dari penggunaan senjata tersebut kemudian mendorong untuk ditemukannya startegi baru dalam era nuklir. Penelitian ini menggunakan metode deskriptif kualitatif dengan menjelaskan bagaimana lahirnya strategi deterrence. Implementasi konsep detterence dapat dilihat hingga saat ini ketika banyak negara-negara berusaha untuk mengembangkan nuklir sebagai stratregi pertahanan negara mereka.
