This research was conducted to determine the coral health condition of genus Porites at Jemeluk beach and Penuktukan beach with the different of reef geomorphology. Coral reef data was collected for two days in Jemeluk beach (reef flats) in March 2017 and in Penuktukan beach (reef slope) in April 2017. Each observation location consisted of 3 stations parallel to the coastline. Observation of coral health data using belt transect method size 2 x 25 m with width of 1 meter each to left and right side. Photo documentation was performed on coral reefs of Porites and subsequently identified the types of diseases and forms of health problems using Coral Disease Handbook, Guidelines for Assessment, Monitoring and Management. The types of coral diseases found in both beaches are ulcerative white spot and white plague. The number of dominant colonies that infected with the disease was found on Jemeluk beach which has coastal morphology of coral reefs. The coral health conditions of the genus Porites found on Jemeluk and Penuktukan beaches are in an unhealthy condition. Compromised health is dominant in Jemeluk beach, this is estimated to be caused by the presence of river flow at observation sites which is relatively high. In addition, the coral reef morphology in Jemeluk beach is reef flat causing the reefs in this area to be more susceptible to damage.

The University of Alabama (UA) Engineers Without Borders™ student chapter has been working for four years with several remote villages in the Amazon Basin in Peru. During the 2006 evaluation project students interviewed villagers and conducted testing to determine the most pressing infrastructure needs: safe water, septic systems, lighting, and communications. In the third year, 2008, a student team began to address the lighting problem by working with the villagers to install photovoltaic solar panels in Amazonian villages. These test installations have been monitored by in-country NGO project collaborators and will continue to be field-evaluated. Meanwhile identical solar units were evaluated in a controlled study at UA during the months of July through September of 2009. The photovoltaic panels were assessed for voltage and current variation with surface and ambient temperature, varying cloud cover and precipitation events. System light outputs were evaluated for luminance. As a whole the systems were also judged based on their performance in on-site operation, maintenance, sustainability and environmental impact. The systems were rated using a comparative weighting and scoring table. Based on the results of the study, two of the systems evaluated were found suitable for large-scale deployment in areas such as the Amazonian region in Peru. Assessing the experience in a post-trip survey, students identified the particular strengths of the
program as the development of teaming, communications, and experiential learning skills.

Published: April 2018

Nepal continues as one of the least developed economies of the world till date. The frequent changes in governance and political instability have contributed to the lack of entrepreneurial dynamism needed for stronger economic growth. Nowadays, bakery industries are the fastest growing small agro-industries leaving the footprint on day to day life in Palpa district. The male and female bakery workers of these industries experience some exigent conditions which prompted us to explore the physical, physiological, and nutritional health status of these bakery workers, with a special reference to the socio-political scenario in Nepal. This study was conducted in the Palpa district of Nepal. 78 male and 44 female bakery workers aged between 30-39 years were chosen for the study, as the young adults are more in this occupation. 38 healthy male and 26 female Bakery workers were chosen as control subjects for the study having same age group. All of them mostly were working as shopkeepers and housewives respectively from the same locality. All the different parameters were examined according to standard methods and Student’s t-test was executed to find out any significant difference (P<0.05) between the selected variables. Both the workers were noticeably healthy. But most of the female bakery workers were having obesity with significantly high obesity related parameters. Again, both the workers exhibited poor cardio-respiratory functions with significantly higher hypertension and peak expiratory flow rate and poor Physical fitness index (PFI) scores. The result suggested that both male and female bakery workers showed abominable conditions, especially the female bakery workers. Hence, there must be some acts to save them by introducing some occupational aids or planned work designs for sustainable economic development.
