  • Aim: To determine whether induced abortion (IA) increases breast cancer (BC) risk. Materials and Methods: A population-based case-control study was performed from Dec, 2000 to November, 2004 in Shanghai, China, where IA could be verified through the family planning network and client medical records. Structured questionnaires were completed by 1,517 cases with primary invasive epithelial breast cancer and 1,573 controls frequency-matched to cases for age group. The information was supplemented and verified by the family planning records. Statistical analysis was conducted with SAS 9.0. Results: After adjusting for potential confounders, induced abortions were not found to be associated with breast cancer with OR=0.94 (95%CI= 0.79-1.11). Compared to parous women without induced abortion, parous women with 3 or more times induced abortion (OR=0.66, 95%CI=0.46 to 0.95) and women with 3 or more times induced abortion after the first live birth (OR=0.66, 95%CI =0.45 to 0.97) showed a lower risk of breast cancer, after adjustment for age, level of education, annual income per capita, age at menarche, menopause, parity times, spontaneous abortion, age at first live birth, breast-feeding, oral contraceptives, hormones drug, breast disease, BMI, drinking alcohol, drinking tea, taking vitamin/calcium tablet, physical activity, vocation, history of breast cancer, eating the bean. Conclusions: The results suggest that a history of induced abortions may not increase the risk of breast cancer.

  • This paper treats with transitional development of medico-hygienical situation in district Yanbian along with the evolution in specific field of medicine. This work is particularly important in shaping TKM identity as TCM embraces Chao medicine asserting it as one included in TCM. This research deals with themes of migration of Chao minorities to this territory and their medico-hygienical situation. Lifted bans on immigration in late Qing dynasty with uncertainty of Korea(Chosun) triggered the immigration to this district. The flow was heavily strengthened under the influence of Westerners and Japanese imperialism into china which consequently provoked the ruin of Qing dynasty, the civil war between republicans and communist and the socio-political changes in Korea. As population growths, the establishment of hospitals and immigration of healthcare professionals were also increased. Though this district is located in Chinese mainland the influence of Japanese was also relevant which lead to medical practice reflecting both sides. Mutual combination and influence of western(contemporary) medicine, TCM and TKM practices made the particularity of Chao medicine.

  • Objective: To understand the domestication and spread of horses in history, genetic information is essential. However, mitogenetic traits of ancient or medieval horses have yet to be comprehensively revealed, especially for East Asia. This study thus set out to reveal the maternal lineage of skeletal horse remains retrieved from a 15th century archaeological site (Gongpyeongdong) at Old Seoul City in South Korea. Methods: We extracted DNA from the femur of Equus caballus (SNU-A001) from Joseon period Gongpyeongdong site. Mitochondrial (mt) DNA (HRS 15128-16116) of E. caballus was amplified by polymerase chain reaction. Cloning and sequencing were conducted for the mtDNA amplicons. The sequencing results were analyzed by NCBI/BLAST and phylogenetic tool of MEGA7 software. Results: By means of mtDNA cytochrome b and D-loop analysis, we found that the 15th century Korean horse belonged to haplogroup Q representing those horses that have historically been raised widely in East Asia. Conclusion: The horse is unique among domesticated animals for the remarkable impact it has on human civilization in terms of transportation and trade. Utilizing the Joseon-period horse remains, we can obtain clues to reveal the genetic traits of Korean horse that existed before the introduction of Western horses.

  • The medical text books used during the Joseon Dynasty can be seen to change over time by examining various records. These records show that the list of medical textbooks suddenly changed a lot between the era of King Sejong and Sejo in the Joseon Dynasty. However, since there are not many studies on this topic yet, this study was conducted and the following causes of these changes were identified: The first reason is the compilation project of Euibangyoochui (醫類聚聚) because the date of compilation of Euibangyoochui is clearly related to the period of change to the list of medical textbooks. The second reason is the difficulty of the medical examination during the Joseon Dynasty. Medical tests in the Joseon Dynasty were very difficult. Therefore, it was too unrealistic to keep 25 or 26 textbooks. Third, there was the problem of supply and demand of medical textbooks. Because the prices of these books were very high at that time, owning 25 or 26 medical books for an individual was a significant financial hardship. This study was able to confirm this through various forms of circumstantial evidence. However, more historical materials should be discovered in the future and research should be conducted to more accurately grasp the situation of the time.

  • Background: This cross-sectional observational study was undertaken to identify the epidemiological characteristics of patients with gynecological malignancies in India, in relation to gynecological cancer risk. Methods: In the gynecology out-patient clinic of a tertiary care hospital in Kolkata, India, the patients with suggestive symptoms of gynecological malignancies were screened. One hundred thirteen patients with histopathologically confirmed gynecological malignancies were interviewed. Results: More than two-thirds of the cases (69.0%) occurred in the age range of 35-64 years and the same proportion of patients was from rural areas. Almost all the patients were "ever-married" (96.5%). More than half (54.9%) were illiterate/just literate. Nearly two-thirds (64.6%) were parity 3 or higher. Among the 18 patients with history of multiple sexual partners of the husband, 94.4% (17) were suffering from cervical malignancy, along with all the 3 patients with history of STD syndromes (sexually transmitted diseases) of their husbands. No one had given a history of condom use by her husband. Most of the patients (91.1%) used old / reused cloth pieces during menstruation. Conclusions: There is a need to increase awareness among women and the broader community about different epidemiological factors that may be responsible for increased risk of gynecological malignancies.

  • The attractiveness of e-sports games1 and the way it is spread has changed in recent years. Instead of conventional approaches, such as advertising campaigns or televised events, spectators are increasingly drawn to online platforms, which offer more opportunities for communication. Besides live streaming services like Twitch. tv, where spectators can watch matches in real-time or via recorded videos, social media platforms like Facebook and Twitter are now adding e-sports related content to their networks [1]. Especially the combination of live streams on Twitch, Twitter, and Facebook opens many possibilities regarding how information is shared. This might be an efficient way of spreading attractiveness among female audiences. This paper focuses on the attractiveness of e-sports events in general for females. It has been hypothesized that there are certain factors that influence this attractiveness. Studying past research papers and online resources, three factors were identified: The players' behavior and charisma, the impact of social media as well as videogames themselves. It is found that females are attracted to e-sport games because they allow them to engage more in the game compared to other videogames. This is because there are no time constraints that require players to accomplish certain tasks within a specific time frame. As such, female gamers can choose how much effort they want to put into the game depending on their personal preferences.
