The presentation of the findings of this article is based on an action research focused on the supportive role of the school in adolescents' lives, whereby Religious Education's contribution to the social and emotional development of adolescents (11-15) is combined with the evaluation of the potential offered by a constructivist approach to the learning process. The research commenced in 2012 and is now in its third "year. The project is based on an intervention at a high school in an impoverished suburb of Athens and researches educational practices through interpretative-ethnographic methods. The researcher has attempted to answer the question of whether the design of the learning environments is effective not only in the learning process, but also on inter-communication and "connectedness" between the members of the learning community. The findings so far indicate a correlation between adolescents' emotional and social wellbeing and the school's approach to knowledge and learning methods, specifically in Religious Education classes. It is fair to say, however, that there exist ethnic, social and family components that are negatively related to a sense of"connectedness" within the school although at the same time Religious Education as a subject is, however, found to be positively related to learning community atmosphere. 展开更多

This study conducted a bibliometric analysis of 1251 articles related to Antarctic krill from 1960 to 2015, based on the Core Collection in Thomson Reuters' Web of Science. We analyzed the results from four aspects: annual distribution, Web of Science categories and the major journals, inter- national collaboration and author keywords. The Antarctic krill research has developed rapidly since 1978, with an increasing article output. The studies mostly focused on the fields of marine and freshwater biology, oceanography, and ecology. Polar Biology, Marine Ecology-Progress Series and Deep-Sea Research Part II-Topical Studies in Oceanography, were the top three journals to publish the Antarctic krill-related papers. Although Russia is the earliest state to report Antarctic krill, U.S.A. and England were leaders with the largest output quantity and the highest cooperation frequencies. The researches in PR China have taken a blooming since 2009 and will play a more and more important role in the world. The frequencies of author keywords were counted. The high-frequency keywords were further divided into four groups with cohesive subgroup analysis, which suggested the major themes. This paper depicts the existing publica- tions on Antarctic krill. Our goal is to serve a point of reference and provide the direction for the future work. 展开更多

Cardiac surgery is a very common operation nowadays all over the world.Median sternotomy is a routine procedure required for cardiac access during open heart surgery.The complications of this procedure after the cardiac surgery range from 0.7% to 1.5% of all cases,and bear a high mortality rate if they occur.Every individual surgeon must pay great attention on every detail during the sternal closure.This article shows the details as to conventional information and updated progress on median sternotomy closure.The update contents involve in biomechanics,number of wires twists,biomaterial and so on.According to our experience,we recommend four peristernal single/double steel wires for sternal closure as our optimal choice. 展开更多

The so-called emotional education is the education of cultivating students' social emotion, promoting their self-control ability and promoting students to correctly cope with the relationship between themselves and surrounding environment. In college English teaching, implementing emotional education not only can teach knowledge to students, but also can help others to form perfect personality, to promote all-round development of students. However, fi'om the present situation, in college English teaching, it generally exists "focusing more on knowledge and less on emotion" phenomenon, which doesn't conform to the requirement of quality education. In college English teaching, conducting emotional education is necessary and imminent. 展开更多

The frequency of invasive cancer in young patients is increasing worldwide. For patients about to undergo a surgical procedure or to receive chemical therapy, radiation therapy, loss or impairment of fertility is a major issue. So the need for fertility protection and preservation became more intensity. Sperm banking is a standard accepted procedure for males to circumvent loss or damage to spermatozoa. Here we present a successful pregnancy in a testicular germ cell tumor patient following fertility preservation. 展开更多

The coordinates of the marked points of joints and the changes of foot force in the human walk motion are obtained with systems of motion image acquisition and force measuring.The effects of kinematics and dynamics on the human lower limb in different loads(0,10,20,30 kg) and walking speeds(0.8,1.3,1.7 m/s) have been investigated using the human dynamics model,.The results were as follows.First,with the increasing load,the dorsiflexion angle of ankle joint increased during the procedure of toe-off,the range of motion of the knee joint decreased,the flexion angle of the hip joint increased,and oppositely,the extension angle of the hip joint decreased.Second,with the increasing speed,the range of motion of the ankle joint,the maximum flexion angle of the knee joint,the flexion angle,extension angle of the hip joint and the range of motion of hip joint increased.Finally,the torque and power of the ankle joint,the knee joint and the hip joint increased with the increasing speed and load.The results can provide an important basis for the mechanism design of lower limb power-assisted exoskeleton. 展开更多

Objective: Present study aimed at further comprehensive functional, histomorphometrical and immunohistochemical assessment of peripheral nerve regeneration using rat sciatic nerve transection model.Methods: The 10-mm rat sciatic nerve gap was created in rats. In control group nerve stumps were sutured to adjacent muscle and in treatment group the gap was bridged using an inside-out vein graft. In sham-operated group the nerve was manipulated and left intact. All animals underwent walking track analysis test 4, 8, and 12 weeks after surgery.Subsequently, muscle mass measurement was performed to assess reenervation, histological examination to observe the sciatic nerve regeneration morphologically and immunohistochemistry to detect Schwann cells using anti S-100. Results were analyzed using a factorial ANOVA with two between-subjects factors. Bonferroni test for pairwise comparisons was used to examine the effect of treatments.Results: Functional analysis ofmyelinated nerve fibers showed that nerve function improved significantly in the time course in treatment group. However, quantitative morphometrical analysis of myelinated nerve fibers showed that there was no significant difference between 8 and 12 weeks in treatment group. Muscle weight ratio was bigger and weight loss of the gastrocnemius muscle was ameliorated by inside-out vein grafting. The position of positive immunohistochemical reactions further implied that regenerated axons and Schwann cell-like cells existed after vein grafting was performed, and was accompanied by the process of myelination and structural recovery of regenerated nerves.Conclusion: Functional analysis of peripheral nerve repair is far more reliable than quantitative morphometrical analysis 展开更多
