In cases where a palatal defect resulting from oral cancer surgery is reconstructed using a free flap, dentures placed on the grafted site, lacking bone support, may experience stability problems due to insufficient support. This case report presents a 41-year-old male patient who underwent a sinus resection due to maxillary sinus carcinoma. The defect was reconstructed using a lateral thigh free flap.After a three-month interim prosthesis phase, a conventional removable partial denture was fabricated. Considering the condition of the remaining teeth and the patient’s age, natural tooth alteration was performed and lingual undercuts of the right posterior teeth were incorporated into the design to compensate for the lack of bone support. Digital occlusal analysis devices and 3D facial scanning were utilized to evaluate changes in occlusion and facial form, and the visualized results were presented to the patient to enhance understanding.

Archaeological research has mainly focused on stone tools, pottery, and metal relics excavated from ruins. Recently, interest in natural relics such as animal bones has increased, as these relics can provide insight into the eating habits, cultural level, and perception of animals of the people at that time. This study investigated morphological structures and dimensions of Nyctereutes procyonoides bones excavated from a well at the Gasan-ri archaeological site in Jinju. These bones are presumed to be relics from the Three Kingdoms period. A total of 447 animal bones were excavated, of which 59 (13.2%) were identified as N. procyonoides bones. These identified bones weighed 47.14 g, accounting for 4.83% of the total bone weight (975.30 g). These N. procyonoides bones were found to belong to 2 individuals estimated to be 5 to 6 weeks old. These bones included 5 skull fragments, 2 mandibles, 9 vertebrae, 11 ribs, 10 forelimb bones, 3 hip bones, and 19 hindlimb bones. A fracture was observed near the bregma of one skull. The presence of a complete specimen in the well suggested that it was used in animal sacrifice rituals. This study estimated the value of animals and human dietary culture at that time by utilizing N. procyonoides bones presumed to be relics of the Three Kingdoms period.

Background: Cancer is a leading cause of death worldwide, posing a significant threat to human health and life expectancy. Numerous existing studies explored the correlation between coal-fired power plants and cancer development. Currently, Chungcheongnam-do Province hosts 29 coal-fired power plants, constituting half of the total 58 plants across South Korea. Methods: This study assessed the cancer incidence by proximity to coal-fired power plants in Chungcheongnam-do Province, Korea. In this study, the exposed group comprised individuals residing within a 2-km radius of the coal-fired power plants, whereas the control group comprised individuals who had no prior residency within the 2-km radius of such plants or elsewhere in the province. Standardized incidence ratios were calculated using the cancer incidence cases retrieved from the National Health Insurance System data from 2007 to 2017. Results: The study found that exposed men had a 1.11 (95% confidence interval [CI], 1.09–1.21) times higher risk of developing all cancer types and a 1.15 (95% CI, 1.09–1.22) times higher risk of developing cancers excluding thyroid cancer compared with control men. Exposed women had a 1.05 (95% CI, 1.00–1.14) times higher risk of developing all cancer types and a 1.06 (95% CI, 0.98–1.13) times higher risk of developing cancers excluding thyroid cancer than did control women. The colorectal, liver, prostate, and bladder cancer incidence rates were significantly higher in exposed men than that in all control groups.The incidence of esophageal, stomach, liver, and lung cancers were significantly higher in exposed women compared with all control groups. Conclusion The residents near coal-fired power plants had a higher risk of developing cancer than did those living in other areas. In the future, long-term follow-up investigations in residents living in the vicinity of power plants are warranted.
