Background: Breast cancer is the most common cancer diagnosed among women in Sri Lanka. Early detection can lead to reduction in morbidity and mortality. The objective here was to identify perceptions of public health midwives (PHMs) on the importance of early detection of breast cancer and deficiencies of and suggestions on improving existing breast cancer early detection services provided through Well Woman Clinics. Materials and Methods: A qualitative study using four focus group discussions (FGDs) were conducted among 38 PHMs in the Gampaha district in Sri Lanka and the meetings were audio-recorded, transcribed and analyzed using constant comparison and identifying themes and categories. Results: All the PHMs had a firm realization on the need of breast cancer early detection. The four FGDs among PHMs revealed non-availability of guidelines, inadequacy of training, lack of skills and material to provide health education, inability to provide privacy during clinical examination, shortage of stationery, lack of community awareness and motivation. The suggestions for the improvements of the programme identified in FGDs were capacity building of PHMs, making availability of guidelines, rescheduling clinics, improving the supervision, strengthening the monitoring, improving coordination between clinical and preventive sectors, and improving community awareness. Conclusions: Results of the FGDs can provide useful information on components to be improved in breast cancer early detection services. Study recommendations were training programmes at basic and post basic levels on a regular basis and supervision for the sustainance of the breast cancer early detection program.

The following paper presents the concept of an earthworm like soft robot for pipe crawling for the inspection of tubes and its design, development, and fabrication process. The soft robot was designed to help in preventing accidents in the industry caused due to faulty pipelines as conventional robots are unable to move through pipes efficiently. The proposed design employs a combination of two radial and one linear actuator fabricated using Ecoflex 00-30 to execute its worm-type locomotion. The radial actuators grip the walls of the pipe while the linear actuator traverses the robot forward. The robot, measuring 240mm in length and 68mm in diameter, was simulated for the expected results and tested in an experimental setup. Experiments were conducted to evaluate the blocked force and radial displacement of the radial actuator, and the linear displacement of the linear actuator against the pressure applied. The experimentation shows that the blocked force is sufficient to grip the tube preventing slip while a significant variation in radial displacement is observed at moderate pressures. The experiments conclude that the optimal usage parameters of the robot is an optimal operating pressure of 20kPa with a speed of 14.4 mm/s.
