Similar to the previous issues, we have been exerting efforts to produce the issue
on time. In this issue we feature two main articles and two communications.

The vehicular traff ic in Metro Manila prompted researchers to use a programming
formulation with binary technique in solving the multi-objective transportation
problem.

The second article is on the toxic effects of copper and zinc on the embryo of the
tropical urchin Tripneustes gratilla. It should be noted that the roe of the test
organism is eaten by the local f isherfolks and is hence economically important.

The importance of quality control and assurance in drug formulations are shown in
the communication on the spectophotometric determination of Losartan potassium
in tablets.

The other communication is a contribution to the literature on Philippine
biodiversity. A note on the biogeographical distribution of the informal group
Basommatophora, a highly ubiquitous group of mollusks, is presented.

It is noteworthy to mention that through  Presidential Proclamation No 737, s. 2014
issued  on 13 March 2014, Dr. Gavino C. Trono Jr. , Professor Emeritus of the Marine
Science Institute, College of Science, UP Diliman, was raised to the rank and title
of National Scientist.  Prof. Trono is recognized for his work on seaweed taxonomy
and culture in the Philippines. With this development, UP Diliman now has three
national scientists who are still active.

Finally, we are very proud and happy to announce that through Commission on
Higher Education Resolution No. 200-2014, Science Diliman has been placed in the
A-2 category, effective this year, until 2016.  Journals under Category A-2 have the
highest accreditation among those not yet indexed in the Web of Knowledge (ISI),
Scopus and other international citation databases. Science Diliman shall also receive
a publication award of PhP 200,000.00 per year from CHED during the period of
accreditation. With this development, all three journals of OVCRD are now Category A
journals. We are thankful to the staff,  led by the managing director Dr. Violeda
Umali,  for the efforts to enable the journals to reach this category.
