培养儿童的思维技能是当前义务教育阶段的探索性教育目标。为了促进教师在思维技能培养领域的专业性发展,一方面教师要不断学习新的教学策略,对接新的教学目标;另一方面,教师需要根据思维技能课堂的复杂性和多变性,开展'行动中的反思'。作为一项个案分析,本研究使用文化心理学的质性分析方法,即复线轨迹等效性模型,从反思实践家的视角,对1名具有代表性的小学教师如何应用思维工具开展学生高阶思维技能培养实践进行了发展过程分析。研究发现,该教师从参加培训到能够开展培养学生的高阶思维技能课,经历了初期学习、课前反思、课后反思、目的反思、批判性观点的获得、行动中的反思6个阶段。其中对应用思维工具的'目的反思'阶段与'批判性观点的获得'阶段是该教师发展过程中具有质的飞跃的重要阶段。这两个阶段的发展源自于大学专家的专业性指导以及与异质性的国外小学教师的思想碰撞。

AIM: To determine the best cut-off value between the early and late recurrence periods after the initial recurrence of hepatocellular carcinoma(HCC).METHODS: The clinical records of 404 patients who underwent macroscopic curative hepatectomy for HCC between 1980 and 2010 were retrospectively examined. We divided the 252 patients experienced a recurrence of HCC into two groups, the early and late recurrence groups using the "minimum P-value" approach. Factors for early recurrence were investigated using all 404 patients, and factors related to late recurrence were investigated in the patients who were confirmed to be recurrence free at the end of the early recurrence ***: For the 252 patients who experienced a recurrence, the optimal cut-off value for differentiating early and late recurrence based on the overall survival after initial recurrence was 17 mo(5-year overall survival after initial recurrence: 15.4% vs 36.3%, P = 0.000018). Cox proportional hazard analysis identified early recurrence(P = 0.003) as one of the independent prognostic factors associated with overall survival after initial recurrence. A logistic regression model showed that an alpha-fetoprotein level > 100 ng/m L(P < 0.001), multiple HCC(P < 0.001), serosal invasion(P = 0.031), and microvascular invasion(P = 0.012) were independent factors associated with early recurrence, whereas the only independent factor related to late recurrence was liver cirrhosis(P = 0.002).CONCLUSION: Seventeen months after hepatectomy is a useful cut-off value between early and late recurrence of HCC based on the prognosis and different etiologies.

针对冷暖空调在夏季制冷和冬季制热运行时,由于室内室外工况差异大而造成系统效率低的情况,本文提出了一种新的可变容量空调系统。该系统在传统空调系统中压缩机排气(或者吸气)的位置接入可变容积的变容装置,通过改变装置的容积吸入或者吐纳制冷剂到循环系统中,以改善制冷剂在不同工况下的循环效率。为了对该可变容量空调系统进行探究,利用焓差实验室对搭建的系统进行了实验研究。实验在室内干湿球温度为27℃/19℃的情况下,测试了系统在室外干球温度29℃和35℃的变容特性。结果表明,在不同的工况下,改变变容装置的容积,调整参与系统循环的制冷剂的质量,有利于提高系统在不同工况下的能效。

Background: In snowy agricultural areas, weeding and snow shoveling are essential activities, and sports activities are common recreational activities. Clarifying the relationships between the degrees of these activities after total hip arthroplasty (THA) and the clinical outcomes may enable us to predict the results of THA for high-load activity patients. Methods: The subjects were 227 post-THA patients who were followed up between 2012 and 2014. Patient-reported outcomes were investigated by the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ) and a questionnaire on postoperative activity. In addition, the Japanese Orthopaedic Association Hip Score (JOA score) was used to quantify hip function. Results: Patients who resumed activities had significantly higher JOA and JHEQ scores than patients who had given up their activities. However, 25.8% of patients had not resumed weeding with a squatting posture. Furthermore, 20% had not resumed sports activities. The most common reason for giving up these activities was fear of implant failure. Conclusions: If the patients were informed that there is no problem restarting their activities after THA, the patients could resume activities and their clinical outcomes may be improved.

Gastric carcinoma is derived from epithelial cells in the gastric mucosa. We reported an extremely rare case of submucosal gastric carcinoma originating from the heterotopic submucosal gastric gland(HSG) that was safely diagnosed by laparoscopy and endoscopy cooperative surgery(LECS). A 66-year-old man underwent gastrointestinal endoscopy, which detected a submucosal tumor(SMT) of 1.5 cm in diameter on the lesser-anterior wall of the upper gastric body. The tumor could not be diagnosed histologically, even by endoscopic ultrasound-guided fine-needle aspiration biopsy. Local resection by LECS was performed to confirm a diagnosis. Pathologically, the tumor was an intra-submucosal well differentiated adenocarcinoma invading 5000 μm intothe submucosal layer. The resected tumor had negative lateral and vertical margins. Based on the Japanese treatment guidelines, additional laparoscopic proximal gastrectomy was curatively performed. LECS is a less invasive and safer approach for the diagnosis of SMT, even in submucosal gastric carcinoma originating from the HSG.

为了提高汽车的燃油经济性,需要进一步减轻零部件的质量。减轻运动件(例如连杆)的质量对于降低相邻运动件的质量尤为重要。采用高强度钢能减小连杆杆身横截面,从而减轻连杆的质量。然而,传统高强度钢的机加工性能很差。因此,开发了1种连杆用的新高强度钢,它以中碳微合金钢为基础,并添加了能够提高屈强比的钒元素。与传统钢相比,新开发的高强度钢的强度提高了10%。采用新高强度钢制造的连杆其质量能减轻8%。这种连杆已从2013年开始进行批量生产,应用于车用发动机。
