Prior to Covid, family involvement was on a forward movement of becoming a more involved, collaborative relationship between teachers and families of students. Just as family involvement was beginning to gain momentum with student-led conferences, in and out of school volunteer opportunities and families being seen as a valued perspective regarding student learning, Covid happened. This one event changed how families were seen within the school system. Through reflection with clinical candidates experiencing the effects of Covid and engagement experiences with families in the classroom, two different themes emerged regarding how schools have moved forward since Covid. Some schools found families to be a valued partner in student learning where other districts chose to use Covid as a reason for shutting the doors to family involvement. This article aims to address the family engagement timeline beginning prior to Covid, the perceptions of clinical candidates based on their experiences in classrooms, and innovative strategies for supporting future engagement with families.

The work provides a summary of family involvement pre-existent to Covid, during the pandemic and post-Covid through a review of the literature and emerging from teacher candidate experiences in the school setting.

After a careful review of literature and reflection of current teacher candidate experiences in the school system, two clear movements have emerged as Covid restrictions have been lowered. Where some districts are relieved by a lowering of visitor restrictions with the increased involvement of families in the building, other schools have tightened restrictions on families, causing increased tension on parent-teacher relationships. These schools are left caught in the pandemic, unaware or unsure of how to proceed in a post-pandemic world. This article provides key aspects to include in creating a plan for engaging with families and creating strong reciprocal relationships.

Valuing families in the school setting is crucial for developing strong relationships among teachers, students, student supports and the families who are raising these children. With increased social emotional needs in students, post-Covid, allowing families to contribute to discussion and planning regarding their children is mutually beneficial. Including families in school learning, planning and opportunities leads to positive family engagement and overall increased success in students, extending to the value educators place on involving these families. In addition, modeling how to postively engage families in school learning supports clinical partnerships with area universities. Where schools and classrooms are developing intergrated plans to include families in school learning experiences, future educators are able to better see and value the role of the family in education. When clinical candidates are not able to observe positive interactions between schools and families, there is a disconnect between school learning and home life that may never be explored.

The purpose of this paper is to simulate the environmental cost reports preparation used to measure environmental performance in realizing eco-efficiency.

This research uses a descriptive case study by using environmental cost detail data from 2011, 2012, 2013 and 2014. The research object is PT Industri Kereta Api (Persero) located in Madiun, East Java.

The result of the research shows that PT INKA (Persero) has not specifically made environmental cost report. It is found that the percentage of total environmental cost to operational cost tends to increase; the cost which gives the biggest distribution of total environmental cost is the prevention cost. By 2014, the effect of environmental costs on operating costs tended to decrease and during 2012–2014 PT INKA successfully maintained the blue star PROPER and the absence of environmental pollution reports.

PT INKA’s environmental performance is still well controlled and since its inception in 2014 PT INKA has succeeded in realizing the concept of eco-efficiency.

Porous implant surface is shown to facilitate bone in-growth and cell attachment, improving overall osteointegration, while providing adequate mechanical integrity. Recently, biodegradable material possessing such superior properties has been the focus with an aim of revolutionizing implant’s design, material and performance. This paper aims to present a comprehensive investigation into the design and development of low elastic modulus porous biodegradable Mg-3Si-5HA composite by mechanical alloying and spark plasma sintering (MA-SPS) technique.

This paper presents a comprehensive investigation into the design and development of low elastic modulus porous biodegradable Mg-3Si-5HA composite by MA-SPS technique. As the key alloying elements, HA powders with an appropriate proportion weight 5 and 10 are mixed with the base elemental magnesium (Mg) particles to form the composites of potentially variable porosity and mechanical property. The aim is to investigate the performance of the synthesized composites of Mg-3Si together with HA in terms of mechanical integrity hardness and Young’s moduli corrosion resistance and in-vitro bioactivity.

Mechanical and surface characterization results indicate that alloying of Si leads to the formation of fine Mg2 Si eutectic dense structure, hence increasing hardness while reducing the ductility of the composite. On the other hand, the allying of HA in Mg-3Si matrix leads to the formation of structural porosity (5-13 per cent), thus resulting in low Young’s moduli. It is hypothesized that biocompatible phases formed within the composite enhanced the corrosion performance and bio-mechanical integrity of the composite. The degradation rate of Mg-3Si composite was reduced from 2.05 mm/year to 1.19 mm/year by the alloying of HA elements. Moreover, the fabricated composites showed an excellent bioactivity and offered a channel/interface to MG-63 cells for attachment, proliferation and differentiation.

Overall, the findings suggest that the Mg-3Si-HA composite fabricated by MA and plasma sintering may be considered as a potential biodegradable material for orthopedic application.
