Background: The aim of this study was to verify the efficacy of lifestyle self-monitoring for the improvement of the IBS and reveal what has been changed due to the intervention. Methods: A total of 111 nursing school students were randomized into three groups, two intervention groups (a two-month intervention group, n = 34, and a four-month intervention group, n = 35) and a control group (n = 34). The intervention groups conducted lifestyle self-monitoring in conjunction with a 15-minutes group work for either two or four months. The primary outcome measure was Rome II criteria for IBS. Other outcome measures were the Hospital Anxiety and Depression Scale (HADS) and the Gastrointestinal Symptom Rating Scale (GSRS). They were assessed at the baseline and the end of both of the intervention periods. Analysis was conducted as intention-to-treat. Results: The prevalence of IBS did not change significantly after the intervention in any of the groups. The HAD-A score, a subscale of the HADS score for anxiety, decreased 1.4 points in the two-month intervention group (p = 0.02) and 2.3 points in the four-month intervention group of (p = 0.01) after intervention. The average GSRS decreased 0.2 points in the control group (p = 0.05) and 0.3 points in the four-month intervention group (p < 0.01). Conclusions: Lifestyle self-monitoring for two or four months did not reduce the prevalence of the IBS significantly, but it did decrease anxiety and improved the QOL related to gastrointestinal symptoms in female nursing school students.

Examining the Hypothesis of Common Factors Shared by Different Addictive Behaviors and Gender Effects on Propensity to Addiction Type

引用

Open Journal of Medical Psychology 2024年第3期13卷 58-70页

作者： masayo Uji Junko Watanabe Toshinori Kitamura Department of Clinical Psychology Human Development Education Graduate School of Education Hyogo University of Teacher Education Kat Japan Academic Skill Support Center Kumamoto Health Science University Kumamoto Japan Kitamura Institute Mental Health Tokyo Tokyo Japan

Background: From the two facts reported by previous research: 1) frequent co-occurrence of more than one addictive behavior, 2) childhood adversities identified as origins of different types of addictive behaviors, it is assumed that all types of addictive behaviors, regardless of substance, behavioral, or relationship, share common factors which have not yet been proven by epidemiological research. The Shorter PROMIS Questionnaire (SPQ) was previously developed to assess 16 types of addictive behaviors. Its factor structure, however, has not been fully investigated. Confirming the factor structure will enable us to hypothesize the common factor(s) shared by all, or if not all, most types of addictive behaviors. Aims: This study aimed at 1) examining the factor structure of the SPQ, 2) confirming the reliability of the questionnaire, and 3) examining the impacts of gender and age on each addictive behavior. Methods: Data obtained from 232 Japanese adults who completed all items of the SPQ were used for the analyses. After confirming the one-factor structure model for each of the 16 subscales, the validity of the one-factor structure of the SPQ was evaluated using Confirmatory Factor Analysis (CFA), by adapting 16 subscale scores as observed variables. If its validity was not confirmed, another model which showed better compatibility to the data was explored. The reliability of the SPQ as well as that of all 16 subscales was evaluated. Also, the impacts of gender and age on each subscale score were examined. Results: The one-factor structure for each of the 16 subscales was confirmed. The compatibility of the SPQ one-factor model was not acceptable. The best fit model was a bi-factor model in which one main factor was shared by all 16 subscales, and three factors were shared by some specific addictive behaviors. Male respondents were more likely than female respondents to show high scores in Alcohol, Tobacco, Gambling, Sex, and Recreational Drugs, and low scores only

Do bosons always condense?

引用

National Science Review 2021年第3期8卷 10-11页

作者： Yoshihiro iwasa Quantum Phase Electronics Center (QPEC) and Department of Applied Physics The University of Tokyo RIKEN Center for Emergent Matter Science (CEMS)

We learn in elementary statistical mechanics that bosonic systems undergo a phase change even without interparticle interactions, called Bose-Einstein condensation (BEC). Indeed, almost all bosonic systems in the real world such as4He, cold atoms and photons, exhibit BEC, and even electrons, a representative fermion system, can show similar condensation and superconductivity through the Cooper pair formation.

Rare Metals 2006年第S1期25卷 550-552页

作者： iwasa Kazuaki SUGAWARA Hitoshi SATO Hideyuki Department of Physics Tohoku University Sendai 980-8578 Japan Department of Physics Tokyo Metropolitan University Tokyo 192-0397 Japan

Elastic neutron diffraction measurements were performed on single crystals to study the ground state below the mysterious exotic transition temperature 0.86 K. An antiferromagnetic order with a tiny moment of 0.027 μB per formula is formed as the ground state for CeOs4Sb12 below the transition point. Our neutron data gives the evidence of spin density wave state for CeOs4Sb12 in this work.

INTRODUCTION The Mongolian gerbil(Meriones unguiculatus)has been used as an animal model for pharmacology(Wu et al.2008),parasitology(Lim et al.2004),and studies of reproduction(Kai et al.1995).The molecular mechanisms of several coat-color phenotypes are known in gerbils(Petrij et al.2001,2007).On the other hand,although albinism in gerbils was first reported by Matsuzaki et al.(1989),its molecular mechanism is still *** a previous study,we reported the establishment of the albino gerbil strain(strain code:MON/Num/c)as a closed colony and the agouti-colored strain(strain code:MON/Num/a)as *** albino strain had 4 nucleotide substitutions and 2 missense mutations(R77H in exon 1 and Q473R in exon 5)in the tyrosinase(Tyr)gene(Ukaji et al.2016).
