Standard Practices

Dear readers,The year 2017 marks the 55th anniversary of the Journal of Information & Communications of the Ministry of Information and Communications, and the 18th anniversary of its scientific publication – the Research and Development on Information and Communication Technology (RD-ICT) journal. Again, the purpose of RD-ICT is to provide a forum for researchers and professionals to disseminate original and innovative ideas in the fields of information technology, communications and electronics in Vietnam and worldwide.Without kind support and invaluable contribution of readers and authors, and hard work of the anonymous reviewers and editors under the former editorship of Prof. Nguyễn Thúc Hải, Prof. Trần Văn Lộc and Prof. Nguyễn Cảnh Tuấn, RD-ICT would not be what it is today – a total of 37 issues in Vietnamese and 14 issues in English.To contribute to the development of research in Vietnam, toward standard practices, high quality and international visibility, RD-ICT has been taking measures by following current practices of prestigious international research journals. In this editorial, we would like to inform you some of the things we have been doing lately.Since June 2014, RD-ICT has applied online journal management and publishing, thanks to the well-known open-source Open Journal System of the Public Knowledge Project, which is used by thousands of online scientific journals worldwide. The editorial board of RD-ICT is currently being extended to include international prominent scientists, thus forming a team of international associate editors, under the complementary technical editorship of Prof. Đỗ Ngọc Minh (University of Illinois at Urbana-Champaign, United States), Prof. Nguyễn Hoàng Hà (University of Saskatchewan, Canada) and Prof. Nguyễn Linh Trung (Vietnam National University, Hanoi). Each submission is now assigned to an associate editor who then coordinates the review process and makes editorial decision.For improved paper quality in terms of organization and presentation, authors are guided to good practice of technical paper writing. In addition, accepted submissions are now copy-edited, by the corresponding associate editors, and laid out using LATEX.Apart from already being an open-access journal, RD-ICT is also looking into other measures to increase its visibility, such as all-English publishing, digital object identification, Google Scholar citation, and SCOPUS indexing.Taking the opportunity of informing the above changes, we would like to, again, express our sincere gratitude and appreciation to the readers, authors, reviewers and editors of RD-ICT, and to the leadership of the Ministry of Information and Communications and its predecessors – the Directorate General of Posts and Telecommunications, the Ministry of Post and Telecommunications – for their continued support and contribution to RD-ICT.We look forward to your comments and feedback for better developing the RD-ICT journal for Vietnam.Sincerely,Vũ Chí Kiên, Editor-in-ChiefĐỗ Ngọc Minh, Nguyễn Hoàng Hà, Nguyễn Linh Trung, Technical Editors-in-Chief

The European rabbit (Oryctolagus cuniculus) introduced into New Zealand in the 183Os, has consistently flourished in Central Otago, the upper Waitaki, and inland Marlborough, all areas of mediterranean climate. It has proved difficult to manage in these habitats. The 'rabbit problem' is largely confined to 105,000 ha of low producing land mostly in semi arid areas of Central Otago. No field scale modifications of the natural habitat have been successful in limiting rabbit numbers. The costs of control exceed the revenue from the land and continued public funding for control operations appears necessary. A system for classifying land according to the degree of rabbit proneness is described. Soil survey and land classification information for Central Otago is related to the distribution and density of rabbits. This intormation can be used as a basis for defining rabbit carrying capacity and consequent land use constraints and management needs. It is concluded that the natural rabbit carrying capacity of land can be defined by reference to soil survey information and cultural modification to the natural vegetation. Classification of land according to rabbit proneness is proposed as a means of identifying the need for, and allocation of, public funding tor rabbit management. Keywords: Rabbit habitat, rabbit proneness, use of rabbit prone land.

Pedotransfer Functions

Kutatásunk célja a víztartóképesség-függvény (VKF) paramétereit az átnézetes térképeink adattartalmával becslő módszerek megbízhatóságának összehasonlítása és továbbfejlesztésük vizsgálata a Magyarországi Részletes Talajfizikai és Hidrológiai Adatbázison (MARTHA).Az irodalomban fellehető módszerek közül VKF-becslő módszert hazai átnézetes talajtérképi információkra eddig egyedül a Kreybig térképekre alkalmazták (Bakacsi et al., 2012). Ők a talaj higroszkópossága (hy) alapján becsülték adott talaj FAO (1995) fizikai féleség kategóriába tartozását. Wösten és munkatársai (1999) és Nemes (2003) pedotranszfer-függvényei alapján rendelték továbbá a talajhoz a fizikai féleség kategóriára meghatározott víztartóképesség-függvény (VKF) van Genuchten paramétereit (HYPRES_hy és HUNSODA_hy módszerek).Bakacsi és munkatársai (2012) eljárását követve, a MARTHA adatbázison vizsgáltuk a hy és az ötkategóriás FAO fizikai féleség kapcsolatát. A fizikai féleség becslését az Arany-féle kötöttség (KA) alapján is kidolgoztuk.Wösten és munkatársai (1999) módszerével meghatároztuk a MARTHA adatbázis talajainak a FAO fizikai féleség kategóriákra jellemző víztartóképességfüggvényeinek van Genuchten paramétereit. A meghatározást a pF6,2 értéken felül a legalább három, majd a legalább öt mért víztartóképesség-értékű talajmintákon végeztük.Megállapítottuk, hogy a KA alapján hatékonyabb a talajminták FAO fizikai féleség kategóriába sorolása, mint a hy alapján.Abban az esetben, amikor nem áll rendelkezésre mechanikai összetétel és a fizikai féleség kategóriába történő besorolást a talaj higroszkópossága alapján végezzük, akkor a VKF-becslés megbízhatósága szignifikánsan rosszabb. Hazai talajmintákon vizsgálva a MARTHA adatbázison pontosított VKF-becslő módszerek szignifikánsan megbízhatóbbak a HYPRES és HUNSODA VKF-becslő módszereinél. A hy-ból kiinduló MARTHA VKF-becslések annak ellenére szignifikánsan megbízhatóbbak a WÖSTEN és munkatársai (1999) módszerénél (HYPRES), hogy utóbbit nem rontja a fizikai féleségbe sorolás hibája.A dolgozat az EU FP7/2007-2013 (Nr. 263188) MyWater és a TÁMOP-4.2.2.A-11/1/KONV-2012-0064 projekt keretében készült. A TÁMOP projekt az Európai Unió támogatásával, az Európai Szociális Alap társfinanszírozásával valósul meg.
