Background This study aimed to investigate the effect of the time from diagnosis to breast cancer surgery on breast cancer patients’ prognosis. Methods Of the 1900 patients diagnosed with invasive (stage 1–3) breast cancer who underwent surgery in KUH between 2012 and 2019, 279 patients were enrolled in this study. All patients, including those who received neoadjuvant chemotherapy, were classified as Model 1 subjects, and those who received immediate surgical treatment were classified as Model 2 subjects. We conducted a Cox regression analysis to identify prognostic factors of breast cancer associated with the time from diagnosis to surgery. Results The univariate results indicated a sharp drop in both groups’ survival rates when the time to surgery was delayed for more than 8 weeks (Model 1 p = 0.000; Model 2 p = 0.001). In the multivariate analysis, the hazard ratio (HR) of Model 1increased (HR = 6.84, 95% CI 1.06–44.25) in response to a delay in surgery of more than 8 weeks. Smoking and the American Joint Committee on Cancer (AJCC) staging system had a negative effect on breast cancer prognosis, while hormone therapy had a positive effect. Conclusion For all patients, a delay in breast cancer surgery of more than 8 weeks was inversely associated with survival.
The recent increase in the tendency of people to marry late or to opt out of marriage entirely is among the key contributors to Korea’s low fertility rate. One possible cause of this tendency may be a change in how marriage is valued among Korea’s youth. The marriage intentions of young adults can be classified into “positive”, “negative”, and “neutral”. Over time, positive marriage intentions have declined across all age groups (2010: 61% → 2020: 39%; ages 25–29), with no significant change in negative marriage intentions. In contrast, neutral marriage intentions have increased significantly (2010: 36% → 2020: 53%; ages 25–29). This phenomenon may be attributable to the increase in the number of young adults who prioritize survival over thinking about the future. However, neutral marriage values can be changed into positive values at any time. A holistic overview of Korean society is necessary to determine how the values of young adults might be influenced to align with a traditional life process.
BACKGROUND Women’s menstrual cycle is an important component of their overall health. Physiological cycles and associated symptoms can be monitored continuously and used as indicators in various fields. Menstrual apps are accessible and can be used to promote overall female health. However, no study has evaluated these apps’ functionality from both consumers’ and health care providers’ perspectives. As such, the evidence indicating whether the menstrual apps available on the market provide user satisfaction is insufficient. OBJECTIVE This study was performed to investigate the key content and quality of menstrual apps from the perspectives of health care providers and consumers. We also analyzed the correlations between health care provider and consumer evaluation scores. On the basis of this analysis, we offer technical and policy recommendations that could increase the usability and convenience of future app. METHODS We searched the Google Play Store and iOS App Store using the keywords “period” and “menstrual cycle” in English and Korean and identified relevant apps. An app that met the following inclusion criteria was selected as a research app: nonduplicate; with >10,000 reviews; last updated ≤180 days ago; relevant to this topic; written in Korean or English; available free of charge; and currently operational. App quality was evaluated by 6 consumers and 4 health care providers using Mobile Application Rating Scale (MARS) and user version of the Mobile Application Rating Scale (uMARS). We then analyzed the correlations among MARS scores, uMARS scores, star ratings, and the number of reviews. RESULTS Of the 34 apps, 31 (91%) apps could be used to predict the menstrual cycle, and 2 (6%) apps provided information pertinent to health screening. All apps that scored highly in the MARS evaluation offer a symptom logging function and provide the user with personalized notifications. The “Bom Calendar” app had the highest MARS (4.51) and uMARS (4.23) scores. The MARS (2.22) and uMARS (4.15) scores for the “Menstrual calendar—ovulation & pregnancy calendar” app were different. In addition, there was no relationship between MARS and uMARS scores (<i>r</i>=0.32; <i>P</i>=.06). CONCLUSIONS We compared consumer and health care provider ratings for menstrual apps. Continuous monitoring of app quality from consumer and health care provider perspectives is necessary to guide their development and update content.

The 11th revision the International Statistical Classification of Diseases and Related Health Problems (ICD) is new classification system suitable for the pace of development of modern technology. Computerization and ontology-based design are expected to be highly scalable and interoperable in integration and connection with other classification systems. However, when introduced in Korea, structural changes are feared to interfere with the linkage between disease codes. This study briefly introduced ICD-11 and examined related literature and mapping case trends. The interest in ICD-11 in Korea was lower than in other countries, and tend to pay attention to socio-economic repercussions. Research was mainly conducted focusing on ‘Chapter 2 Neoplasms’ and ‘Chapter 6 Mental, behavioural or neurodevelopmental disorders’. Through a mapping case study, it was confirmed that ICD-11 is a highly useful classification system, and guidance on post-coordination, such as the sequence and criteria of the expansion code, is needed. Proper preparation is required until ICD-11 is officially implemented in Korea. The role of the government is important at all stages from the introduction to maintenance of ICD-11, and efforts and attention to adaptation of all classified users in the health care industry are needed.
