Driven by both technology and market, telecom industry is becoming a part of several converged industries in information society gradually from an independent industry which provides telecom products like voice or data. Under such background, this paper introduces a new value chain model of telecom value-added services in the new environment, providing theoretic support for transformation of te...

Additive Number Theory can be best described as the study of sums of sets of integers. A simple example is given two subsets A and B of a set of integers, what facts can we determine about A + B where A + B := {a + b | a ∈ A and b ∈ B}? We will state a result regarding this example shortly. We note that a very familiar problem in Number Theory, namely Lagrange’s theorem that every nonnegative i...

Laboratory studies were conducted to determine the effect of temperature and cold storage on the performance of Tetrastichus brontispae (Ferriere) (Hymenoptera: Eulophidae), one of the major endoparasitoids against coconut hispine beetle, Brontispa longissima (Gestro) (Coleptera: Chrysomelidae). The results revealed that T. brontispae could successfully parasitize host pupae under all seven tes...

The incorrect generic name Perisphaeria Burmeister, 1838 results from a mistake by Princis (1947). Perisphaeria is an incorrect spelling by Burmeister referring to Perisphaerus Serville, 1831. Princis (1947) incorrectly regarded Perisphaeria as proposed by Burmeister and as the senior synonym of Hyposphaeria Lucas, 1863, which is valid. The subfamilial name Perisphaeriinae based on Perisphaeria...

IT security incidents pose a major threat to the efficient execution of corporate strategies. Although, information security standards provide a holistic approach to mitigate these threats and legal acts demand their implementation, companies often refrain from the implementation of information security standards, especially due to high costs and the lack of evidence for a positive cost/benefit...

Compliance with law, industry standards, and corporate governance regulations are one of the driving factors for discovering security requirements. This paper aims to incorporate constraints from regulations through security requirements at an early stage of development. Constraints are extracted using a pattern based approach from legal texts of information security laws and policies derived f...

This paper describes different proposals made at UNED, for post-graduated students, at the area of IT Services Management and specially trying to fill the gap, of paramount importance, of the treatment due in ITIL® (Information Technology Infrastructure Library) to Information Security Management. We analyze the treatment given to Information Security Management in ITIL, both versions 2 and 3, ...

In this paper, after giving a brief definition of Information Security Management Systems (ISMS), ISO 27001, IT governance and COBIT, pros and cons of implementing only COBIT, implementing only IS
