The purpose of this paper is to compare two UNESCO reports on educational development in Cambodia, one from 1955 and the other from 2010, in order to understand how the global education development agenda has impacted shadow education.

The study is conducted through a textual comparison of two UNESCO reports written 50 years apart.

Although the educational problems facing Cambodia were similar in both reports, the recommendations differed in important ways. The 1955 report advised the country to expand slowly access to education in order to maintain quality, while the 2010 recommended quickly expanding access. A major difference found in the reports regarded the issue of fees in schooling, which did not appear in 1955. School fees in Cambodia are typically extracted through the system of private tutoring, known in the academic literature as shadow education. Such an insight, this paper argues, suggests that the difference in development approach between the two reports is one of the reasons shadow education has flourished in the country.

Through a historical comparison of development efforts in one country, it becomes clear that the education development agenda is partly to blame for the rise of shadow education.

Today, the presence of unwanted activities threatening the safety of the field, which has negative effects on daily life and social psychology, is increasing day by day. There is no doubt that it is inevitable to avoid these threats, but it is possible to take some measures to reduce the destructive power of these threats. Nowadays, increasing terrorist attacks increase the importance of field safety design in urban areas. There is a loss of life in attacks around the world. The subject of this study is to investigate the design criteria related to the built environment and the measures to be taken in the case of bomb attacks in the built environment. In this study, a checklist will designed to measure the security design process around the building. The checklist titles are taken mainly from the “Safety design and Landscape Architecture” series of the Landscape Architecture Technical Information Series/LATIS publications by the American Society of Landscape Architects (ASLA) and the Risk Management Series of the Federal Emergency Management Agency/FEMA (FEMA, 2003, 2007; LATIS, 2016) and others. The checklist created as a result of literature review will be tested in Istanbul Sultanahmet Square. As a result of the study, it was determined that improvements should be made in the areas of vehicular and pedestrian access, parking lots, lighting and trash receptacle designs around Sultanahmet Square.

The purpose of this paper is to present a methodology which enables to measure and analyze the performance of sub-process and overall system of a cargo company.

Network data envelopment analysis method with fuzzy data is used for performance measurement which considers the sub-process efficiency simultaneously together with the overall efficiency and also the uncertainty included in input–output data.

A real-life application of the proposed model is presented for Turkey. The application results show the efficiency scores of ten branches according to each sub-process and also the overall system. Although the obtained results are case specific, the application results indicate that the inefficient branches can achieve efficiency either by decreasing circulation ratio input for human resources sub-process or by increasing closed complaint output or by decreasing open complaint output for customer relationship management sub-process.

The study presented provides insights into the performance measurement applications in cargo sector. The methodology presented provides the flexibility of removing or adding some new sub-processes and also decision-making units which enables the approach to be used for other performance evaluation problems.

This paper aims to reduce part defects and improve ceramic additive manufacturing (AM). Selective laser melting (SLM) experiments were carried out to explore the effect of laser power and scanning speed on the microstructure, melting behaviour and surface roughness of cuprous oxide (Cu₂O) ceramic.

The experiments were designed based on varying laser power and scanning speed. The laser power was changed between 50 W and 140 W, and the scanning speed was changed between 170 mm/s and 210 mm/s. Other parameters, such as scanning strategy, layer thickness and hatch spacing, remain constant.

Laser power and scan speed are the two important laser parameters of great significance in the SLM technique that directly affect the molten state of ceramic powders. The findings reveal that Cu₂O part defects are widely controlled by gradually increasing the laser power to 110 W and reducing the scanning speed to 170 mm/s. Furthermore, excessive laser power (>120 W) caused surface roughness, cavities and porous microstructure due to the extremely high energy input of the laser beam.

The SLM technique was used to produce Cu₂O ceramic specimens. SLM of oxide ceramic became feasible using a slurry-based approach. The causes of several part defects such as spattering effect, crack initiation and propagation, the formation of porous microstructure, surface roughness and asymmetrical grain growth during the SLM of cuprous oxide (Cu₂O) are thoroughly investigated.
