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.
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).

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.

Crocus sativus L. is a crop grown for spice production, and large amounts of residues from the flowers are produced during the process. The underutilized by-product from saffron spice production, the C. sativus tepals, was investigated as a promising raw material of natural bioactive compounds using light spectrum manipulation in controlled environments. The plants were grown under either light-emitting diodes (LEDs) or natural light (NL, greenhouse). LED experiments were performed in controlled-environment chambers (120 µmol m–2 s–1of photosynthetically active radiation, 18 °C, 16-h photoperiod). The LED treatments used were as follows: (i) red ʎ = 660 nm (62%) and blue ʎ = 450 nm (38%) (RB); and (ii) red ʎ = 660 nm (50%), green ʎ = 500–600 nm (12%), and blue ʎ = 4 50 nm (38%) (RGB). Flower growth parameters, total phenols, total flavonoids, flavonols, flavonol glycosides, and antioxidant properties were measured in harvested tepals. Floral by-products from plants grown under the two LED treatments accumulated higher amounts of antioxidant compounds compared to those of plants grown under NL. The total flavonoids content was significantly enhanced in the RGB LED treatment, while the corolla fresh weight significantly declined in the same treatments. The higher content of bioactive secondary metabolites in plants grown under both RB and RGB light environments resulted in increased antioxidant capacity measured by DPPH free-radical scavenging capacity and the ferric reducing antioxidant power method. These results indicate that manipulation of LED spectra could boost secondary metabolites and antioxidant capacity to obtain phytochemically enriched floral by-products with superior functional quality.
Questionnaire on Marine Safety and Vessel Traffic Services in Philippine Coastal Waters (Part 2)

Part 2 of the Questionnaire Survey on Marine Safety and VTS in the Philippine Coastal Waters presents the alternatives to risk reduction, modifying the VTS, the qualification and competency of a VTS operator and effectiveness of the services and assistance rendered by VTS. This study finds that majority of respondents chose "Improved education and training of mariners" as the best alternative to risk reduction and the "Strict enforcement of ship safety regulations" as the best alternative based on the respondents' ranks last served onboard and areas of familiarity. In modifying the VTS, the areas with VTS chose to "Improve or upgrade" and for those without, is to "Implement" the system. The best VTS system is the "Port and Approaches" type and the PCG is selected to operate, maintain and supervise the system. As a VTS operator, the necessity of shipboard experience is considered "Essential" and the experiences include "Ship-handling and Communication", and "Management level" experiences. The effectiveness of the assistance and services rendered by VTS are considered "Very Important". Based on these findings, this study recommends improvement of education and training of mariners and users of the waterways including the training of VTS operators manning the VTS centers, strict enforcement of ship safety regulations along the busy and main ports of the country and installation of VTS system with the most appropriate type with the supervision of PCG.
