The level dd principal congruence subgroup of SL(n;Z)\textrm{SL}(n;\mathbb{Z})

We give a finite generating set for the level $d$ principal congruence subgroup $\Gamma_d(n)$ of $\textrm{SL}(n;\mathbb{Z})$. As an application, we determine the abelianization of $\Gamma_d(n)$. By this abelianization, it follows that the finite generation set for $\Gamma_d(n)$ is minimal. Moreover, we give a finite presentation for $\Gamma_2(n)$.Comment: 10 page

Final report of the Committee on Gynecologic Oncology, the Japan Society of Obstetrics and Gynecology, on a fact-finding questionnaire on the status of treatment of hereditary breast and ovarian cancer syndrome in Japan

Hereditary breast and ovarian cancer syndrome (HBOC) is a hereditary tumor that can be definitively diagnosed by detection of germline mutation of the BRCA1 or BRCA2 gene. The HBOC Public Awareness and Management Sub-committee of the Tumor Committee, Japan Society of Obstetrics and Gynecology carried out a fact-finding survey on the status of treatment of HBOC in Japan. The directors of medical specialty teaching facilities were notified of the questionnaire by post, with the request for one respondent per facility. The response period was from 8 July 2014 to 31 March 2015. Of the 678 facilities that were asked to compete the questionnaire, 341 (50.3%) responded. The responses are shown in the respective tables. For questions with free responses, similar answers have been grouped together, and the written answers have been freely translated. Based on these results, the Japan Society of Obstetrics and Gynecology considers that the 14 conditions, including consultations by specialist staff, must be met before risk-reducing salpingo-oophorectomy is carried out

Research Trends and Issues Related to Prevention of Infectious Diseases in Early Childhood

本論は，幼児期の健康教育の中でも感染症予防に焦点を当て，近年の研究の動向について，「保育施設における取組みに関する研究」「幼児が実践する感染予防に関する研究」「感染症予防に関する保育者の意識に関する研究」「保育施設と関係機関との連携に関する研究」「保育者養成校における感染症予防教育に関する研究」に分類し考察したものである。幼児を対象とした感染症予防に関する研究成果は，小児保健分野における研究成果が多く，保育実践を対象とした研究は，手洗いに関する論考が散見されるものの，具体的な教育内容や指導法等の実践に直結した研究は未だ進んでいない。感染症対策が強く求められる中で，今後，保育現場の実情に即した様々な観点からの研究の推進が望まれる。In this study, we focused on prevention of infectious diseases (PID) in health education of early childhood, classified into following five researches and discussed recent trends: Research related to 1) approaches in childcare facilities, 2) infection preventive measures undertaken by young children, 3) childcare workers’ consciousness on PID, 4) cooperation between childcare facilities and related institutions, and 5) education for PID in childcare training schools. Many research results in child health have been reported on PID for young children. However, in researches for childcare practice, while handwashing is often discussed, few attempts have been made at a study connected with practices such as concrete educational contents or methods. Because of strong demand for PID, it’s necessary to research from various viewpoints based on the actual circumstances in childcare

Social comparison and self-stereotyping : Gender of compared targets influences self-perceptions of men and women <Article>

This study examined whether gender differences in self-rated personality traits are context dependent. Japanese university students rated themselves on positive and negative aspects of agency (masculine) and communion (feminine) traits in three comparative conditions: between-gender, within-gender, and control conditions. Results indicated that men perceived themselves as less feminine with regard to the positive aspects of communion than women in the intergroup comparison condition. Men in the intergroup condition had significantly lower ratings for the positive aspects of communion, compared to those in the other two conditions; however, these ratings were provided only by men with low social dominance orientation. Additionally, no significant differences were observed among women. Thus, the gender self-stereotyping process among men was discussed.本研究の一部はJSPS科研費（課題番号263808440）の助成を受けた

Effect of ventilated workwear and working schedule on physiological and psychological responses of construction workers, no. 2: Actual investigation at an active construction site

Although the use of cooling garments to prevent heat disorders has been increasing, the effectiveness of such garments at construction sites (CSs) remains underexplored. We investigated the relationship between the thermal environment at a CS and the physiological and psychological responses of workers wearing/not wearing ventilated work wear (VWW). The study participants were rebar placers and form workers employed at an outdoor CS. The thermal environmental conditions and the physiological and psychological responses of the workers were measured. The overall, chest, and forearm skin temperatures of the workers not wearing VWW were significantly higher than those of workers wearing VWW. To clarify the effects of VWW and working schedules on body weight loss (BWL), the BWL rate was simulated based on the evaporation rate according to a regression formula of measured data in an artificial chamber. The BWL during the late shift was higher than that in the early shift, causing dehydration in the afternoon. To prevent this condition, more water intake is required during the late shift

Electrical stimulation using conductive polymer polypyrrole promotes differentiation of human neural stem cells: a biocompatible platform for translational neural tissue engineering

Conductive polymers (CPs) are organic materials that hold great promise for biomedicine. Potential applications include in vitro or implantable electrodes for excitable cell recording and stimulation, and conductive scaffolds for cell support and tissue engineering. Here we demonstrate the utility of electroactive CP Polypyrrole (PPy) containing the anionic dopant dodecylbenzenesulfonate (DBS) to differentiate novel clinically relevant human neural stem cells (hNSCs). Electrical stimulation of PPy(DBS) induced hNSCs to predominantly β-III Tubulin (Tuj1) expressing neurons, with lower induction of glial fibrillary acidic protein (GFAP) expressing glial cells. In addition, stimulated cultures comprised nodes or clusters of neurons with longer neurites and greater branching than unstimulated cultures. Cell clusters showed a similar spatial distribution to regions of higher conductivity on the film surface. Our findings support the use of electrical stimulation to promote neuronal induction and the biocompatibility of PPy(DBS) with hNSCs, and opens up the possibility of identifying novel mechanisms of fate determination of differentiating human stem cells for advanced in vitro modelling, translational drug discovery and regenerative medicine

Risk factors for perioperative venous thromboembolism: A retrospective study in Japanese women with gynecologic diseases

BACKGROUND: Patients with gynecologic cancer have a high risk of venous thromboembolism (VTE) like patients with other cancers. However, there is little information on risk factors for VTE during gynecologic surgery and no uniform preventive strategy. Our objectives were to identify risk factors for perioperative VTE in gynecologic patients and establish methods for prevention. METHODS: We analyzed 1,232 patients who underwent surgery at the Department of Obstetrics and Gynecology of St. Marianna University School of Medicine between January 2005 and June 2008. We investigated (1) risk factors for preoperative VTE, (2) use of an inferior vena cava (IVC) filter, and (3) risk factors for postoperative VTE. RESULTS: There were 39 confirmed cases of perioperative VTE (3.17%), including 25 patients with preoperative VTE and 14 with postoperative VTE. Thirty-two patients had cancer and seven patients had benign diseases. Twenty-two of the 32 cancer patients (68.7%) had preoperative VTE, while postoperative VTE occurred in 10 cancer patients. Multivariate analysis indicated that ovarian cancer, tumor diameter ≥10 cm, and previous of VTE were independent risk factors for preoperative VTE. Among ovarian cancer patients, multivariate analysis showed that an age ≥50 years, the presence of heart disease, clear cell adenocarcinoma, and tumor diameter ≥20 cm were independent risk factors for preoperative VTE. The factors significantly related to preoperative VTE in patients with benign disease included previous VTE, age ≥55 years, tumor diameter ≥20 cm, and a history of allergic-immunologic disease. Thirteen of the 25 patients (52%) with preoperative VTE had an IVC filter inserted preoperatively. Postoperative screening (interview and D-dimer measurement) revealed VTE in 14/1,232 patients (1.14%). Multivariate analysis indicated that cancer surgery, a history of allergic-immunologic disease, and blood transfusion ≥2,000 ml were independent risk factors for postoperative VTE. CONCLUSIONS: Perioperative VTE is often fatal and preventive measures should be taken in the gynecologic field, especially when patients have the risk factors identified in this study. Since VTE is often present before surgery, preoperative screening is important and use of an IVC filter should be considered
