A Manga-Driven System Requirements Development PBL Exercise
We conducted a Project-Based Learning (PBL)-type exercise incorporating
Japanese cartoon (manga) techniques into Requirements Development (RD)
processes. Manga has established techniques, such as those for character
setting and story development, that we thought are also valid for RD processes.
Using this manga-driven method, students were able to clarify high-level
project goals early in the development life-cycle, and succeeded in defining
high quality and unique system ideas.Comment: SEEM201
An optimization method for designing high rate and high performance SCTCM systems with in-line interleavers
We present a method for designing high-rate, high-performance SCTCM systems with in-line interleavers. Using in-line EXIT charts and ML performance analysis, we develop criteria for choosing constituent codes and optimization methods for selecting the best ones. To illustrate our methods, we show that an optimized SCTCM system with an in-line interleaver for rate r = 5/6 and 64QAM has better performance than other turbo-like TCMs with the same parameters

Comparison of Urinary Levels of 8-Hydroxy-2’-deoxyguanosine between Young Females with and without Depressive Symptoms during Different Menstrual Phases
This study aimed to clarify the association between depressive symptoms and a marker of oxidative stress-induced DNA damage in young females. Since the menstrual cycle may confound or modify this association, depressive symptoms and urinary levels of 8-hydroxy-2ʼ deoxyguanosine (8-OHdG) were evaluated during each menstrual phase. A total of 57 female fourth-year students (aged 21.6±0.8) from a Japanese health science university were studied. The menstrual cycle was divided into 3 phases:menstrual (days 1 to 3 after the onset of menses);proliferative (days 13 to 15);and secretory (days 24 to 26). Depressive symptoms were assessed by the self-rating depression scale (SDS). Positive depressive symptoms were defined as a score of 53 or more during 2 different menstrual phases. The association between the presence of depressive symptoms and 8-OHdG levels adjusting for the menstrual cycle was examined by two-way analysis of variance with the menstrual cycle (menstrual, proliferative, and secretory phases) as the within-individual factor. The menstrual cycle did not show a significant correlation with urinary 8-OHdG levels. On the other hand, the menstrual cycle-adjusted 8-OHdG level was significantly higher in those with depressive symptoms (7.01ng/mL) than in those without them (3.98ng/mL). The ROC curve analysis showed that urinary 8-OHdG levels had reasonably high discriminative performance throughout all the menstrual cycles (0.73-0.81;all p<0.05). These results indicated the presence of oxidative stress in subjects with depressive symptoms independent of the menstrual cycle
The Impact of Medical Students Teaching Basic Life Support to Laypersons
Basic life support (BLS) courses for laypersons, including cardiopulmonary resuscitation (CPR) training, is known to improve outcomes of out-of-hospital cardiac events. We asked medical students to provide BLS training for laypersons as a part of their emergency medicine education and evaluated the effects of training on the BLS skills of laypersons. We also used a questionnaire to determine whether the medical students who provided the BLS training were themselves more confident and motivated to perform BLS compared to students who did not provide BLS training. The proportions of laypersons who reported confidence in checking for a response, performing chest compressions, and automated external defibrillator (AED) use were significantly increased after the BLS training. The proportions of medical students who reported increased confidence/motivation in terms of understanding BLS, checking for a response, chest compression, use of AED, and willingness to perform BLS were significantly greater among medical students who provided BLS instructions compared to those who did not. BLS instruction by medical students was associated with an improvement in laypersons’ CPR accuracy and confidence in responding to cardiac arrest. The results indicate that medical students could gain understanding, confidence, and motivation in regard to their BLS skills by teaching BLS to laypersons
