Pancreatic metastasis from malignant phyllodes tumor (PT) of the breast is rare, and only a few cases have been reported in the literature. Here, we report a case of pancreatic metastasis from malignant PT of the breast in a 48-year-old woman. She had had three episodes of recurrence of malignant PT in her right breast. She presented with epigastric pain for 2 months. Computed tomography and magnetic resonance imaging revealed a 6 cm-sized, well-defined, heterogeneous mass with peripheral enhancement in the body of the pancreas. Endoscopic ultrasonography-guided fine-needle aspiration was performed, and the pathologic report suggested spindle cell mesenchymal neoplasm. Subsequently, surgical excision was performed, and the mass was confirmed as a metastatic malignant PT. The imaging findings are discussed and the literature is briefly reviewed in this report.

With the implementation of the "Critical Disaster Punishment Act" in 2022, the safety and health management system within the organization is being established and awareness of the importance of safety culture is spreading. Measuring the level of safety culture in an organization can grasp the perception and attitude of members about safety. You can also identify the safety-related problems and improvements of the organization. In this study, prior studies on the safety culture level scale were considered, focusing on domestic literature studied from 2001 to 2021. Domestic literature was analyzed by research period, research field, author, core terms, and constituent factors of scale. The implications of the research trend analysis results of the safety culture level scale were derived.

This paper is proposing a novel machine scheduling model for the unrelated parallel machine scheduling problem without setup times to minimize the total completion time, also known as "makespan". This problem is a NP-complete problem, and to date, most approaches for real-life situations are based on the operator's experience or simple heuristics. The new model based on the Memetic Algorithm, which was proposed by P. Moscato in 1989, is a hybrid algorithm that includes genetic algorithm and local search optimization. The new model is tested on randomly generated datasets, and is compared to optimal solution, and four scheduling models; three rule-based heuristic algorithms, and a genetic algorithm based scheduling model from literature; the test results show that the new model performed better than scheduling models from literature.

This article explores how Richard Powers' The Gold Bug Variations, an interdisciplinary novel through the new concepts of biocriticism and bioliterature is connected with literature/art and science/technology. Powers uses Edgar Allen Poe's "The Gold Bug" and Johann Sebastian Bach's "The Goldberg Variations" for decoding DNA in order to analogize a genomic metaphor. He imagines literature as "the book of life" genome, written by DNA code due to the complexity and multiplicity of the genome. His novel, as 'genomic narrative,' shows the articulation of the genomic reading, and expression in the life language through the discourses of the information technology and the rhetorical tropes in biology. New biological ideas are continually required to articulate these processes. In the present tendency of the Human Genome Project, such advanced devices as biocybernetics offer the potential to open up new possibilities to researching the complexity of the genome. This can only happen if the following two ideas are followed: One is to comply with advanced technologies for processing the rapidly increasing data of the genome sequence; The other is to admit the necessary paradigm shift in biology. As shown above, the complexity and multiplicity of the genomic reality is not so simple. We must go beyond determinism, even if representation of a biological reality reveals the possibility of expressing its constituent elements by the advanced biotechnology. Consequently, in the unstoppable advances of the art of decoding the genome, The Gold Bug Variations interrelates to the interdisciplinary approaches through the rhetorical tropes that unfold the complex discursive world of the genome. Powers shows that the complex mechanisms of the genome in the microworld of every cell as the plot of "the book of life" can be designed and written using DNA language. At the same time, his genomic reading and writing demonstrate the historical processes of the shifting center of new genomic development and polysemous interpretation.

This study aims to investigate the definition of and factors in decision on socio-scientific issues and to analyze the standards for the quality of decision-making, based on the review of studies in socio-scientific issues. This study analyzed 147 articles published in journals of the social science citation index, and the research method was followed by taxonomy analysis and analytic induction. The results showed that many of the studies did not explicitly articulate the decision-making and only dealt with a specific element of the process, not as a whole. Decision-making was categorized into the steps of identification, option, criteria, information, survey, choice, and review. In terms of the factors, the literature tackled diverse things: science knowledge, nature of science, type of issue, discussion type, belief & values, and culture. This study examined the relationship between the factors and each element of decision-making. Among the relationships, only six kinds were shown as relevant and most of factors were connected to survey. With regard to the standards, the literature relied upon balance, justification and multiplicity since many of the studies made use of Toulmin-based argumentation. This study gives some implications for standards for decision-making regarding the nature of risk and uncertainty.

Pharyngocutaneous fistula is a relatively common, but serious complication after pharyngeal or laryngeal cancer surgery. It can cause wound infection, longer hospitalization period and sometimes carotid artery rupture which can be fatal. Recently, we experienced a 63-year-old larynx cancer patient who had dementia and alcoholic liver cirrhosis for underlying diseases. He underwent total laryngectomy and both neck dissection, and pharyngocutaneous fistula occurred during postoperative radiotherapy. Pharyngocutaneous fistula during postoperative radiotherapy has not yet reported in the literature, and there are few reports about pre and postoperative management of dementia patient after head and neck cancer surgery. Therefore, we report this case with a brief review of literature.

Objectives : In Korea the practice of folk remedies is widely spread. One of the main uses is the utilization of pumpkin in postpartum edema. While this practice is widely propagated no one could exactly define the evidence of its uses. Therefore we aimed to provide literature evidence of correct prescription in postpartum edema. Methods : As the use of pumpkin in postpartum edema is particular to korea, we revised all the medical book published from the 17th century, the time supposed to have been introduced pumpkin in Korean peninsula. We also researched the prescription mainly used in postpartum edema, and the common main herbal component, succium. As pumpkin and succium is homophony to 'Ho bak' in korean it had the possibility of being misinterpreted. Results : On our literature research we found the precautions of pumpkin to provoke gi-stagnatio and dampness obstruction and that it was restricted while the recovery of all kind of diseases as well as in puerperium. The main reason of postpartum edema is caused by blood stasis which when the blood gains its normal circulation, edema is dispersed by itself. For this propose main prescription was Jogyeongsan調經散 type with its main component succium which medical properties are cited in all medical classics consistently. From the literature of "Juchonsinbang" and "Uibanghapbu" we found three different prescriptions, Hobakgo琥珀膏, Hobakgo胡朴膏, and Namgwago南瓜膏 which contents and their medical proposes were equal. Conclusions : By these finding we could refer that the use of pumpkin in postpartum edema was caused by homophonic reasonal misinterpretation of succinum in korean. This research provides the literature evidence to correct pumpkin's misuse and also the necessity of restriction of the use of even most common products for medical proposes and/or at least the importance of being guided by the experts.

Background: A review of the literature was carried out to study dust and sandstorm (DSS) in terms of its ecosystem processes and relationship to other dryland disasters in Northeast Asia. Drylands are ecosystems that include grasslands, semi-deserts, and deserts, and these types of ecosystems are vulnerable due to their low primary productivity that depends on a small amount of precipitation. Results: Drought, dust, desertification, and winter livestock disasters (called dzud) are unique natural disasters that affect the region. These disasters are related in that they share major causes, such as dryness and low vegetation cover that combine with other conditions, wind, cold waves, livestock, and land-surface energy, to dramatically impact the ecosystem. Conclusions: The literature review in this study illustrates the macroscopic context of the spatial and temporal patterns of DSS according to geography, climate, and vegetation growth in the drylands of Northeast Asia. The effects of ocean climates and human activities were discussed to infer a possible teleconnection effect of DSS and its relations to desertification and dzud.
