Purpose: The male predominance in the incidence of gastric cancer (GC) is established; however, sex differences in the prognosis of GC remain controversial. As such, this study analyzed the prognosis of patients with GC based on age and sex. Materials and Methods: Data from 14,739 patients diagnosed with GC at Seoul National University Bundang Hospital between 2003 and 2023 were analyzed. Baseline characteristics, histological types of GC, overall and GC-specific survival rates (age and stage stratification), and associated risk factors were analyzed. Results: Females were significantly younger (p < 0.001) and exhibited more gastric body cancers (p < 0.001) and tumors with diffuse-type or poorly differentiated histology (p < 0.001) than males. Females exhibited an advantage over males in terms of overall survival (p=0.004), but not in GC-specific survival. However, age stratification revealed significant sex differences, that females < 50 years of age exhibited survival disadvantages (p < 0.001); however, this trend was reversed with age, and females > 60 years exhibited survival advantages (p < 0.001) for both overall and GC-specific survival. This may be explained by the lower ratio of diffuse-type GC as females age. Furthermore, in the analysis according to stage, females with stage IV disease exhibited significant survival disadvantages, with significantly younger age and a higher proportion of diffuse-type GC which exhibits aggressive features, resulting in poorer survival than in males. Conclusion Age and stage stratification revealed significant differences in survival between the sexes, which can be helpful for public health strategies.

The medical journal publishing environment in Korea has changed rapidly since the 2010s owing to the expanded influence of international indexing databases, changes in research performance evaluation systems, and the strengthening of research and publication ethics. Amid these changes, the Journal of Yeungnam Medical Science (JYMS) has successfully advanced from a local journal to an international journal through a series of strategic transformations, including the appointment of a Managing Editor in 2011, conversion to an English journal in 2018, introduction of an online manuscript submission and peer review system in 2020, and transition to continuous article publishing in 2025. Consequently, it has been indexed in major international indexing databases, including the Directory of Open Access Journals (DOAJ), PubMed, PubMed Central, Scopus, and Emerging Sources Citation Index (ESCI). Notably, in 2025, international submissions increased substantially, with foreign authors accounting for 79.1% of the total submissions. In addition, citation metrics such as Journal Impact Factor and CiteScore increased. These achievements were supported by the dedicated efforts of the editorial board members, volunteer peer reviewers, and the local and international authors who submitted high-quality manuscripts, together with the establishment of standardized editorial policies and systematic quality control procedures. However, practical challenges remain, including financial constraints, staffing structures, workflow continuity, and difficulties securing peer reviewers. The JYMS case demonstrates that journal internationalization is a long-term process enabled by sustained investment, establishment of professional infrastructure, and organizational support. This suggests that collective academic commitment and stable operational systems are essential for the sustainable development of journals.

Alterations in gait patterns often indicate health status, and their analysis enables the diagnosis and assessment of various health conditions. This study aimed to develop a noncontact gait analysis system using red, green, and blue-depth (RGB-D) cameras and to evaluate its potential clinical applicability. A single case study was conducted to assess changes in the gait patterns of a patient with stroke before and after the application of an ankle-foot orthosis. Twenty walking trials were recorded to evaluate the key gait parameters. The custom RGB-D camera-based gait analysis system demonstrated the potential to rapidly quantify key gait parameters in the patient. Compared with normative data, it effectively identified characteristic stroke-related gait impairments such as shorter step lengths and slower gait speeds. However, the intraclass correlation coefficient analysis indicated low measurement reliability. Although the stance time and minimum knee angle on the left and right sides exceeded the standard error of measurement (SEM), no changes exceeded the minimal detectable change (MDC) criteria. Moreover, other gait parameters did not show significant changes beyond SEM or MDC, limiting the interpretability of the results. Therefore, further technological developments and data collection are required to improve test-retest reliability and sensitivity to change.

After a year of exchange in Montreal, a South Korean academic physiatrist and his Canadian colleague have reflected on the strengths and weaknesses of their respective healthcare systems. They have focused more specifically on physiatrist-delivered pain medicine treatments. This article is written based on personal perspectives. It aims to present the differences between the systems in South Korea and Quebec, highlighting the issues arising from each system and providing perspectives on potential solutions.

Accurate measurement of the foot contact area is crucial for diagnosing pes planus (flatfoot) and pes cavus (high arch), which significantly affect pressure distribution across the plantar surface. This study aimed to develop a program using ChatGPT-4 to automate foot contact area measurements using a podoscope, thereby enhancing diagnostic precision. A 53-year-old female volunteer stood on a podoscope to capture images of her feet, which were processed to isolate the foot contours and measure the contact areas. A program developed utilizing ChatCPT-4 was designed to outline the feet, detect contact areas, and calculate their sizes and ratios. The results demonstrated clear visualization of foot contours with automated calculation of the contact area and its ratio to the total foot area. The entire foot area measured 1,091,381.00 pixels, with a contact area of 604,252.50 pixels. The ratio of the ground contact area to the entire foot area was calculated as 55.37%. This method, which employs advanced image-processing techniques powered by ChatGPT-4, demonstrates the potential for integrating artificial intelligence into clinical applications. This approach could improve diagnostic precision and patient outcomes through personalized treatment strategies.
