Changes of Department Structures in Japanese Private Universities : An analysis of influence of demography and industrial structure

The purpose of this paper is to analyze the changes of department structures in Japanese Private Universities between 2000-2015. Size and departmental organization of all education and childcare as well as engineering school/colleges were analyzed. Generally colleges of education and childcare field expanded their size due to big demands for teachers and childcare workers. It was found that organizational structure were influenced mainly by the location of the institutions. Engineering schools in metropolitan areas expanded their size and number of departments. Smaller colleges/schools in provincial areas tended to changes their structures more. They decreased their capacity of engineering schools and created new schools/colleges other than engineering more. These results imply the strong influence of the demographic factors and the selectivity of the institutions. Prospect of provincial colleges/schools are discussed.本研究は，科学研究費助成金基盤研究(C)「社会変動と教育研究組織の再構築」（平成25-27年度）の成果の一部である

Prehospital emergency care patient satisfaction scale [PECPSS] for care provided by emergency medical teams: Scale development and validation

The purpose of this study was to develop and validate an emergency medical technician (EMT) care patient satisfaction scale to measure patient satisfaction with prehospital emergency care. To date, patient satisfaction surveys of EMTs have been performed subjectively, e using each facility's questionnaire, without the use of a validated patient satisfaction scale. However, no specific scale has been devised to assess patient satisfaction with EMTs. The study population comprised patients who used an ambulance between November 2020 and May 2021 (N = 202). A survey instrument was administered to participants who provided informed consent. In the process of validating the patient satisfaction scale, an exploratory factor analysis (EFA) of construct validity was performed. The results of the EFA showed a factor structure consisting of five factors: “teamwork”, “explanation and communication”, “physical treatment and psychological support”, “quickness of transport”, and “environment in the ambulance”. In addition, domain and summary scores showed good internal reliability (Cronbach's range = 0.82–0.94). The patient satisfaction scale developed in this study was designed and validated considering the role of EMTs and patients' needs for prehospital care. This scale may be useful in the development of assessments and interventions to improve patient satisfaction with EMTs

Management of Occluded Metallic Stents in Malignant Hilar Biliary Stricture

Background/Aims: Little is known about the management of occluded multiple metallic stent (MS) deployed in malignant hilar biliary strictures (HBS). The purpose of this study was to evaluate the endoscopic management of occluded multiple MSs deployed in HBS. Methodology: Fifty-five patients with unresectable biliary tract carcinoma had multiple MSs inserted due to HBS. The endoscopic intervention through the duodenal papilla was performed on 30 cases that had MS occlusion. The procedure success rate, the survival time after the procedure and the number of endoscopic interventions before death were analyzed, retrospectively. Results: The causes of MS obstruction were tissue ingrowth (n=20), sludge (n=7), tumor overgrowth (n=2), and hemobilia (n=1). Endoscopic cleaning or deployment of plastic stents or metallic stents was performed on these patients and was successfully accomplished only via the transpapillary approach. The survival time after MS obstruction was 219 days. The median number of endoscopic interventions before death was 3. The median interval of endoscopic intervention after the first plastic stent occlusion was 84 days. Conclusions: Our long-term data regarding the endoscopic management of occluded MSs deployed in malignant hilar biliary strictures are acceptable although the patency time of plastic stents deployed after MS occlusion was relatively short

Japanese cross-cultural validation study of the Pain Stage of Change Questionnaire.

Introduction:Although evidence supports efficacy of treatments that enhance self-management of chronic pain, the efficacy of these treatments has been hypothesized to be influenced by patient readiness for self-management. The Pain Stage of Change Questionnaire (PSOCQ) is a reliable and valid measure of patient readiness to self-manage pain. However, there is not yet a Japanese version of the PSOCQ (PSOCQ-J), which limits our ability to evaluate the role of readiness for pain self-management in function and treatment response in Japanese patients with chronic pain.Objective:Here, we sought to develop the PSOCQ-J and evaluate its psychometric properties.Methods:We recruited 201 patients with chronic pain. The study participants were asked to complete the PSOCQ-J and other measures assessing pain severity, pain interference, catastrophizing, self-efficacy, and pain coping strategies.Results:The results supported a 4-factor structure of the PSOCQ-J. We also found good to excellent internal consistencies and good test-retest reliabilities for the 4 scales. The Precontemplation scale had weak to moderate positive correlations with measures of pain-related dysfunction and maladaptive coping. The Action and Maintenance scales had weak to moderate positive correlations with measures of self-efficacy and adaptive coping. The Contemplation scale had weak positive correlations with measures of pain interference and both adaptive and maladaptive coping.Conclusions:The PSOCQ-J demonstrated adequate psychometric properties in a sample of Japanese patients with chronic pain. This measure can be used to evaluate the role that readiness to self-manage pain may play in adjustment to chronic pain in Japanese pain populations

Effect of Class Size and Teaching Methods on Pupil's Academic Achievement : Application of Structural Equation Models and Multilevel Models

Effects of the class size and teaching methods on academic achievement of Japanese pupils of thirty four elementary schools at three cities are analyzed by using generalized linear model, structural equation models and multilevel models. It was found that class size, team-teaching and small group teaching had no or very small effects on pupil's achievement. But, some teaching methods, such as reading book activity in the morning before formal lesson, and not-one-way teaching found to have a significant effect on achievements. It was also found that order in the classroom had positive significant effect on average achievement of the schools

Educational Effect of Class Size and Teaching Methods on Teaching and Learning : Differences among Subjects of Junior High School Teachers

Teaching and learning in public junior high school were assessed by teachers. It was found that class size has negative effect on student's learning in math. And it has also negative effect on teacher's teaching in Japanese, Social Studies, Science and English. The smaller the class size is, the easier the teaching. It was also found that small group teaching method was useful especially in English

Hyperkalemia caused by rapid red cell transfusion and the potassium absorption filter

We report a case of transient hyperkalemia during hysterectomy after cesarean section, due to preoperatively undiagnosed placenta accreta that caused unforeseen massive hemorrhage and required rapid red cell transfusion. Hyperkalemia-induced by rapid red cell transfusion is a well-known severe complication of transfusion; however, in patients with sudden massive hemorrhage, rapid red cell transfusion is necessary to save their life. In such cases, it is extremely important to monitor serum potassium levels. For an emergency situation, a system should be developed to ensure sufficient preparation for immediate transfusion and laboratory tests. Furthermore, sufficient stock of preparations to treat hyperkalemia, such as calcium preparations, diuretics, glucose, and insulin is required. Moreover, a transfusion filter that absorbs potassium has been developed and is now available for clinical use in Japan. The filter is easy to use and beneficial, and should be prepared when it is available

Effects of epinephrine administration in out-of-hospital cardiac arrest based on a propensity analysis

Background: Epinephrine administration has been advocated for cardiopulmonary resuscitation (CPR) for decades. Despite the fact that epinephrine administration during CPR is internationally accepted, the effects of the prehospital epinephrine administration still remain controversial. We investigated the effects of epinephrine administration on patients with out-of-hospital cardiac arrest based on a propensity analysis with regard to the ‘CPR time’. Methods: From April 1, 2007, to December 31, 2009, 633 out-of-hospital cardiac arrest patients with bystander witnesses were included in the present study. To rule out any survival bias, we used the propensity scores, which included CPR time. CPR time was defined as the time span from when the emergency medical technicians started CPR until either the return of spontaneous circulation or arrival at the hospital. After performing propensity score matching, the epinephrine and no-drug groups each included 141 patients. The primary study endpoint was a favorable neurological outcome at 30 days after cardiac arrest. Results: After propensity score matching, the frequency of the return of spontaneous circulation before arrival at the hospital in the matched epinephrine group was higher than that in the matched no-drug group (27% vs. 13%, P = 0.002). However, the frequency of a favorable neurological state did not differ between the two groups. With regard to the frequency of a favorable neurological state in the patients, the adjusted odds ratio of the time span from cardiac arrest to the first epinephrine administration was 0.917 (95% confidence interval 0.850–0.988, P = 0.023) per minute. Conclusions: In patients with witnessed out-of-hospital cardiac arrest, prehospital epinephrine administration was associated with increase of the return of spontaneous circulation before arrival at the hospital. Moreover, the early administration of epinephrine might improve the overall neurological outcome
