Marine Transportation in the Philippines
Orlando S. Dimailig,Jae-Yong Jeong,Chol-Seung Kim 한국항해항만학회 2011 한국항해항만학회지 Vol.35 No.4
This paper details the maritime accidents that occurred in the Philippines from 1972 to 2010. Firstly, it describes the general maritime situation in the country. It was followed by the traffic and safety infrastructure and the prevailing weather in the archipelago. The third section deals with the accidents’ statistics and their geographical locations which is further sub-divided into three regions. It is grouped according to 10-year period. This paper describes the actual maritime situations, the pertinent national regulations, the inter-agencies policies and their safety regimes. It illustrates the shipping environment in the country including the maritime aids and infrastructure and the on human element factors.

This paper investigates minimum safe distances relative to a ship’s four cardinal sides, as perceived by Filipino navigators when encountering dangerous elements and in adverse weather conditions when maneuvering in and around harbors. It uses a descriptive research method in the form of a questionnaire survey for experienced Filipino navigators of various ranks. During the course of research, 71 responses were colleted and the resulting data is presented in graphical and tabulated forms. Statistical methods including Pearson-product moment correlations, Cronbach’s Alpha and ANOVA were used to identify internal associations, consistencies and significances, respectively. It has been proven that there are no significant differences in minimum safe distances relative to a ship’s four cardinal sides, whether maneuvering while approaching a port or within an inner harbor. This study has been deemed significant for training future navigators, managing traffic in fairways, and designing harbors and maneuvering areas in the approaches to ports, among other applications. This work can also be used as a preliminary study for comparison with the well known safe domains presently in use.
Diversity of the genus Sheathia (Batrachospermales, Rhodophyta) in northeast India and east Nepal

Freshwater red algae of the order Batrachospermales are poorly studied in India and Nepal, especially on a molecularbasis. During a survey in northeast India and east Nepal, six populations of the genus Sheathia were found and analyzedusing molecular and morphological evidence. Phylogenetic analyses based on the rbcL gene sequences grouped allpopulations in a large clade including our S. arcuata specimens and others from several regions. Sheathia arcuata representsa species complex with a high sequence divergence and several smaller clades. Samples from India and Nepal weregrouped in three distinct clades with high support and representing new cryptic species: a clade formed by two samplesfrom India, which was named Sheathia assamica sp. nov.; one sample from India and one from Nepal formed anotherclade, named Sheathia indonepalensis sp. nov.; two samples from Nepal grouped with sequences from Hawaii and Indonesia(only ‘Chantransia’ stages) and gametophytes from Taiwan, named Sheathia dispersa sp. nov. Morphologicalcharacters of the specimens from these three species overlap one another and with the general circumscription of S. arcuata, which lacks the heterocortication (presence of bulbous cells in the cortical filaments) present in other species ofthe genus Sheathia. Although the region sampled is relatively restricted, the genetic diversity among specimens of thesethree groups was high and not closely related in the phylogenetic relationship with the other clades of S. arcuata. Thesedata corroborate information from other groups of organisms (e.g., land and aquatic plants) that indicates this region(Eastern Himalaya) as a hotspot of biodiversity.
Thorea indica sp. nov. (Thoreales, Rhodophyta) from Uttar Pradesh, India
Orlando Necchi Jr.,Monica O. Paiano,John A. west,E. K. Ganesan,Susan Loiseaux de Goër 한국조류학회I 2015 ALGAE Vol.30 No.4
Thorea indica sp. nov. is described from the Sai River, Uttar Pradesh, India (26°39′00.7″ N, 80°47′38.3″ E). Its classification is based on molecular sequences of the plastid-encoded RuBisCO large-subunit gene, rbcL and the barcode region of the mitochondrial encoded cytochrome c oxidase subunit 1, cox1, and morphological data. The sequence analyses confirm a new species of Thorea. The cox1 barcode sequence had 90.4-90.8% identity with Thorea sp. from Australia and Thorea hispida from Hawaii and China. Based on rbcL sequences the Indian specimen was positioned in a major clade with high support (>95 bootstrap and 0.95 posterior probability) containing two other species: T. okadae from Japan and T. hispida from the continental USA, Hawaii, the UK, and China. The divergences among these sequences were T. indica vs. T. okadae (2.8%) and T. indica vs. T. hispida (2.9-3.4%). The comparison of morphological characters of Thorea from India was not conclusive due to the inadequate descriptions in previous reports: most specimens reported as T. hispida fit within the circumscription of T. indica as described here. The previous report of T. siamensis from the Sai River is incorrect and the specimens fit within our description of T. indica. Thorea indica and T. okadae can be distinguished by minor morphometric characters and sexuality (dioecious vs. monoecious).
Trajectory Data Warehouses: Design and Implementation Issues
Orlando, Salvatore,Orsini, Renzo,Raffaeta, Alessandra,Roncato, Alessandro,Silvestri, Claudio Korean Institute of Information Scientists and Eng 2007 Journal of Computing Science and Engineering Vol.1 No.2
In this paper we investigate some issues and solutions related to the design of a Data Warehouse (DW), storing several aggregate measures about trajectories of moving objects. First we discuss the loading phase of our DW which has to deal with overwhelming streams of trajectory observations, possibly produced at different rates, and arriving in an unpredictable and unbounded way. Then, we focus on the measure presence, the most complex measure stored in our DW. Such a measure returns the number of distinct trajectories that lie in a spatial region during a given temporal interval. We devise a novel way to compute an approximate, but very accurate, presence aggregate function, which algebraically combines a bounded amount of measures stored in the base cells of the data cube. We conducted many experiments to show the effectiveness of our method to compute such an aggregate function. In addition, the feasibility of our innovative trajectory DW was validated with an implementation based on Oracle. We investigated the most challenging issues in realizing our trajectory DW using standard DW technologies: namely, the preprocessing and loading phase, and the aggregation functions to support OLAP operations.
Acquisition and transmission of selected CTV isolates by Aphis gossypii

Citrus tristeza virus (CTV) is a severe threat to the citrus industry. Disease symptoms and severity may varydepending on the CTV isolates. These are responsible for the decline of trees grafted on sour orange rootstock,or stem pitting on some citrus commercial cultivars regardless of rootstock. In the Calabria region (Italy), CTVwas first reported on cultivars imported from other countries. However, recent observations suggested thatnatural spread of CTV was occurring and a study was needed to determine the epidemiological status andaphid transmission of CTV in Calabria. The role played by local A. gossypii in the spread of CTV was analyzed inthe laboratory using various viral acquisition, inoculation periods with three different CTV isolates. Singleaphid vectors acquired CTV after a minimumof 30 min acquisition access period (AAP) and were able to transmitthe virus after a 60 min inoculation access period (IAP) to healthy plants. A minimumof four aphid vectorswereneeded to reach 50% transmission probability. The results suggested that the three tested strains are transmittedby A. gossypii in a semi-persistent mode. The results demonstrated that local A. gossypii population can acquireand transmit efficiently the tested virus isolates with serious implications on the virus spread.
