UNESCO has continued to work in Africa, especially in the six southern sub-Saharan countries, and Asia, where international cooperation is needed. The CLC (Rwanda Community Learning Center) covered in this study aims to create a regional learning center in Rwanda and to recover local communities and provide learning environment. During the course of this study, we conducted field trips for actual planning and reviewed the current state of educational and cultural facilities that recently opened and are operated, and found implications. In consultation with the Rwandan Educational Commission, the site for CLC was decided, the building was designed, and the construction is about to start. The results of this study are as follows. First, in addition to the efforts of the activists in the village, which can be considered the smallest unit of a local community, the approach for establishing an architectural space and active education and community environment can be evaluated as a result of experimental efforts. Second, we can pay attention to the attempts to realize local communities. The bridge business is based on the multi-purposes such as early childhood education, technical education for adults, and community restoration of local residents and it reflects space and program plans for this purposes. It also reflects detailed plans such as differentiating the flow planning depending on users' time of use. Third, we can explain the characteristics of architectural planning considering local characteristics such as active use of local materials. Due to the characteristics of a developing country, there were significant considerations on maintenance, and to this end, the plan included plans for the environment and use of materials that are easily maintained. In addition, the participation of local residents in the process of establishment was suggested as a possibility to serve an educational role.

Flooding usually brings in disruptions and aggravated congestions to the roadway network. Hence, right information should be provided to road users to avoid the flood-impacted areas and for city officials to recover the network. However, the information about individual link congestion may not be conveyed to roadway users and city officials because too many links are congested at the same time. Therefore, more significant information may be desired, especially in a disastrous situation. This information may include 1) which places to avoid during flooding 2) which places are feasible to drive avoiding flooding. Hence, this paper aims to develop a framework to identify the flood-impacted areas in a roadway network and their criticality. Various impacted clusters and their spatiotemporal properties were identified with field data. From this data, roadway users can reroute their trips, and city officials can take the right actions to recover the affected areas. The information resulting from the developed framework would be significant enough for roadway users and city officials to cope with flooding.

This study build finite element analysis (FEA) models describing the bending events of coiled tubing (CT) at the wellhead and trips into the hole, accurately provide the state of stress and strain while the CT is in service. The bending moment and axial force history curves are used as loads and boundary conditions in the diametrical growth models to ensure consistency with the actual working conditions in field operations. The simulation diametrical growth results in this study are more accurate and reasonable. Analysis the factors influencing fatigue and diametrical growth shows that the internal pressure has a first-order influence on fatigue, followed by the radius of the guide arch, reel and the CT diameter. As the number of trip cycles increase, fatigue damage, residual stress and strain cumulatively increase, until CT failure occurs. Significant residual stresses remain in the CT cross-section, and the CT exhibits a residual curvature, the initial residual bending configuration of CT under wellbore constraints, after running into the hole, is sinusoidal. The residual stresses and residual bending configuration significantly decrease the buckling load, making the buckling and buckling release of CT in the downhole an elastic-plastic process, exacerbating the helical lockup. The conclusions drawn in this study will improve CT models and contribute to the operational and economic success of CT services.

Constructionarium Ltd is a not-for-profit organisation which delivers a residential, experiential, immersive learning opportunity to university students from across the built environment education sector. Since 2002, the Constructionarium education model has been available to students in engineering, construction management and architecture at a purpose built, 19-acre multi-disciplinary training facility in Bircham Newton, England simulating real site life and reflecting site processes, practices and health and safety requirements. The unique approach of Constructionarium puts experiential learning and sustainability at the heart of everything. In a week, students develop a practical understanding of the construction process, develop transferable skills, build a team and are exposed to the latest in sustainable technologies. Experiential learning is what differentiates a Constructionarium project from regular field trips or site visits. At Constructionarium the focus is on learning by participation rather than learning through theory or watching a demonstration. The projects cannot be replicated in a classroom or on campus. Using the hands-on construction of scaled down versions of iconic structures from around the world, students learn that it requires the involvement of the whole construction team to successfully complete their project. Skills such as communication, planning, budgeting, time management and decision making are woven into a week-long interrelationship with industry professionals, academic mentors and trades workers. Working together to enhance transferable skills brings the educational environment into the reality of completing an actual construction project handled by the students. Constructionarium has used this transformational learning model to educate thousands of students from all over the United Kingdom, Europe and Asia. Texas A&M University in the United States has sent multiple teams of students from its Department of Construction Science every operational year since 2016.

This paper described the types and characteristics of educational programs in major natural history museums of the world. Data were collected from the websites, annual reports, and written materials of the Natural History Museum at London, Australian Museum at Sydney, Field Museum of Natural History at Chicago, Smithsonian Museum at Washington D.C, Royal Tyrrell Museum at Canada and American Museum of Natural History at New York. As the result of this study, we presented ten types of educational programs, which were moveable museums, workshops, lecture/courses, festival/events, discovery activities, scientific exploration/research projects, field trips, youth curators/internship, loan materials and camp/tours. We also described the examples equivalent to each program type. The characteristics of educational programs provided by museums as informal learning settings were analyzed in terms of their themes, participation levels, connection with exhibition, relation to curriculum, and learning activity levels. Information in this paper will assist science teachers, museum educators and curators: (1) to design and implement various types and contents of educational programs; (2) to use characteristics of educational programs to assess and develop them; (3) to make important contributions to science education that involves the introduction of various scientific aspects and collections to the public, and the use of programs for science learning and teaching coherent to existing curricula.

The purpose of this study were to develop PBL(problem-based learning) program, and to examine the effects of PBL. This paper applied PBL to a "Culture of Clothing" class, comprised of 23 undergraduate students majoring in Home Economics. As part of the PBL curriculum, the class assigned students to design and create brochures about the culture of clothing by going on field trips to the National Folk Museum of Korea. The class met for five weeks, 3 hours per week. The effectiveness of PBL was measured based on the students' self-reflective journals, self-assessments, and satisfaction surveys. The study gathered three major feedbacks from the students after taking the PBL class. First, the students recognized the importance of cooperation and communication in problem-solving process. Second, the students appreciated that students themselves were implementing the self-directed learning. Third, the students were satisfied with the overall quality of the PBL class, based on their feedbacks and surveys. However, the students' self-assessments show their acknowledgement of the lack of creativity and critical-thinking skills. The study also observed relatively low-satisfaction ratings about the learning environment at the National Folk Museum of Korea.
