  • The crinoid specimens of the genus Anneissia were collected from Nokdong, Korea Strait, and Moseulpo, Jeju Island. The specimens were identified as Anneissia pinguis (A.H. Clark, 1909), which belongs to the family Comatulidae of the order Comatulida. Anneissia pinguis was first described by A.H. Clark in 1909 around southern Japan. This species can be distinguished from other Anneissia species by a longish and stout cirrus, much fewer arms, and short distal cirrus segments. The morphological features of Korean specimens are as follows: large disk (20-35 mm), 28-36 segments and 32-43 mm length cirrus, division series in all 4 (3+4), very stout and strong distal pinnule with 18-19 comb and 40 arms. In Korea fauna, only three species of genus Anneissia were recorded: A. intermedia, A. japonica, and A. solaster. In this study, we provide the morphological description and phylogenetic analysis based on cytochrome c oxidase subunit I.

  • The ocean environment offshore West Africa is considered to be mild. However, the generated swell from distant North and South Atlantic during austral winter and summer can reach high wave amplitudes with relatively low wave periods or low wave amplitudes with long wave periods, the later can be a crucial scenario to consider when the assessment of vessel resonance is of importance. Most offshore operations, which include offshore drilling, and installation in West Africa, are carried out from floating systems. The response of these systems and performance are governed by characteristics, such as amplitude and frequency of the wave and swell seas. It is therefore important to fully understand the sea conditions offshore Nigeria. This study covers the description of the swell sea offshore Nigeria using Bonga offshore wave measurements collected from the directional wave-rider (DWR), positioned at the Bonga site off the coast of Nigeria.

  • This paper deals with the design and development of a real-time integrated communication architecture for heterarchical SFCS(Shop Floor Control System). In autonomous agent-based heterarchical SFCS, each functional unit of parts and resources is equipped with an intelligent controller (agent) that acts as the representative of the entity. The controllers communicate and negotiate with other controllers on a real-time basis through message passing and bidding protocol to achieve mutual agreements for task sharing. ICPL(Integrated Communication Protocol and Language) is proposed for this purpose. ICPL is a language and a protocol for supporting communication among intelligent controllers. Based on the speech act theory, this paper proposes a semantic description for ICPL that associates the description of the cognitive states of controllers with the use of language primitives (message_type). Semantics for the basic set of ICPL messages is described. Eventually, an ICPL-based communication architecture can provide the implementation of the distributed and heterarchical SFCS, and makes the intelligent controller transparent to the negotiation problem.

  • This study analyzed an operational concept for the D Information Resource Management Information System (DIRMIS) to manage any IT resources effectively in defense area. We first deduced the concept of the information resource management (IRM) for defense area from the literature review, and we suggested a guideline, which has used in defense area, of the documentation for the operational concept description (OCD). Moreover, we developed the operational concept for the DIRMIS following the guideline. Especially, this study is a practical approach for suggesting of a case, and the share of accumulated cases will contribute to advance in System Integration (SI) industry as well as academic research.

  • This study proposes an ontology design framework to support the cooperation among devices by using PROLOG, Conceptual Graph (CG), and Resource Description Framework (RDF). Quite a large number of representation languages for representing ontology on the Web have been established over the last decade. Most of these researches are focused on design of independent resources description. In Semantic Web, however, cooperation ontology will be needed. In this study, the CG could make an entire conceptual view of knowledge and RDF can represent that knowledge. Then the PROLOG could support the natural inference based on that knowledge. Therefore, our proposed ontology will be used in the designing of Semantic Web-based cooperation systems.

  • A new species, Venturia tenuiabdominalis Choi sp. nov., belonging to the subfamily Campopleginae, family Ichneumonidae, is described in South Korea. The subfamily Campopleginae was recorded by Forster in 1869 based on genus Campoplex and more than 2,100 described species into 66 genera have been reported worldwide. Among the 66 genera of Campopleginae, the genus Venturia is one of the large groups, which is more than 140 species worldwide (Yu et al., 2016; Vas, 2019a; 2019b; Vas, 2020; Vas and Di Giovanni, 2020; Han et al., 2021). A taxonomic study of South Korean Venturia was initiated by Choi et al. (2012), who reported Venturia longipropodeum (Uchida, 1942). A key to species of South Korean Venturia, description of new species and diagnostic illustrations are provided.

  • The family Trigonalyidae Cresson, 1887, is a small group of parasitic wasps (Hymenoptera: Apocrita) comprising around 150 species worldwide. Among them, the genus Taeniogonalos Schulz, 1906 is the richest in species and the most widely distributed. Four species, namely T. fasciata, T. mongolica, T. subtruncata and T. tricolor, were recorded from the Korean Peninsula. The genus is studied here on the basis of a larger collection of material from South Korea. Six species of Taeniogonalos are recognized, including three species that are newly recorded: T. formosana, T. sauteri and T. taihorina. The published record of T. mongolica in Korea currently seems groundless, and this species should be excluded from the Korean fauna. A key to species identification is provided, with illustrations and description of each species. The hitherto unknown male of T. sauteri is described. We also present new biological data on T. sauteri and T. formosana, including the record of a new family of Diptera as secondary hosts for the family.
