  • Purpose: This descriptive study aimed to identify the menstrual cycle characteristics and premenstrual syndrome (PMS) prevalence in Korean young adult women using the retrospective and prospective Daily Record of Severity of Problems (DRSP). Methods: In the first stage, participants included 151 nursing students studying in a university located in Seoul. Data were collected from April 20 to June 2, 2017, using the questionnaire on menstrual characteristics, pictorial blood assessment chart, and retrospective DRSP. In the second stage, participants included 17 students with PMS, based on the screening conducted in the first stage. Data were collected using the prospective DRSP from May 29 to 2 September 2, 2017. Results: Of the study sample, 104 participants (68.9%) had regular periods. Those with regular periods had 11.97 periods annually with a menstrual cycle of 29.38 days and a period duration of 5.72 days. Fifty-five participants (37.4%) showed menorrhagia. Sixty-four participants (42.4%) were found to have PMS based on their retrospective DRSP. When the ratio of women (52.9%) with PMS shown in the prospective DRSP was used as a positive predictive value, the estimated PMS prevalence was 22.4%. Conclusion: This study provides clinically significant PMS prevalence among Korean young adult women, positive predictive value of the retrospective DRSP, and valid data to basically understand the menstrual cycle characteristics experienced by these women.

  • Backgrounds/Aims: Pancreaticoduodenectomy (PD) is commonly performed pancreatic procedure for tumors of periampullary region. Delayed gastric emptying (DGE) and pancreatic fistula are the most common specific complications following PD. DGE can lead to significant morbidity, resulting in prolonged hospital stay and increased cost. Various factors might influence the occurrence of DGE. We hypothesized that kinking of jejunal limb could be a cause of DGE post PD. Methods: Antecolic (AC) and retrocolic (RC) side-to-side gastrojejunostomy (GJ) groups in classical PD were compared for the occurrence of DGE in a prospective study. All patients who underwent PD between April 2019 and September 2020 in a tertiary care center in south India were included in this study. Results: After classic PD, RC GJ was found to be superior to AC in terms of DGE rate (26.7% vs. 71.9%) and hospital stay (9 days vs. 11 days). Conclusions: Route of reconstruction of GJ can influence the occurrence of DGE as RC anastomosis in classical PD provides the most straight route for gastric emptying.

  • With the advent of the AI, the need to use AI in the field of education is widely recognized. The purpose of this study is to shed light on how prospective mathematics teachers perceive the need for AI and the role of teachers in future mathematics education. As a result, with regard to teaching, prospective teachers recognized that the use of AI in school mathematics is a demand of a new era, that various types of lesson can be implemented, and that accurate knowledge and information can be delivered. On the other hand, they recognized that AI has limitations in having cognitive and emotional interactions with students. As for mathematics learning, the prospective teachers recognized that AI can provide individualized learning, be used for supplementary learning outside of school, and stimulate students' interest in learning. However, they also said that learning through AI could undermine students' ability to think on their own. With regard to assessment, the prospective teachers recognized that AI is objective, fair and can reduce teachers' workload, but they also said that AI has limitations in evaluating students' abilities in constructed-response items and in process-focused assessment. The roles of teachers that the prospective teachers think were to conduct a lesson, emotional interaction, unstructured assessment, and counseling, and those of AI were individualized learning, rote learning, structured assessment, and administrative works.
