  • One of the small genera of the tribe Atrophini (subfamily Banchinae), the genus Amphirhachis, has been reported seven species in the world. Among them, four species (Amphirhachis fasciata, A. nigripalpis, A. rubriventris and A. tertia) from Oriental region, and four species(Amphirhachis fujiei, A. miyabi, A. nigra and A. tertia) from Eastern Palaearctic region. Unfortunately, there are no records in South Korea yet. This genus is easily distinguished from other genera of Atrophini following: clypeus strongly convex near side; posterior transverse carina of propodeum represented by a weak or faint vertical ridge at apex on each side; ovipositor sheath shorter than metasoma. In this study, the genus Amphirhachis is recorded for the first time with a newly recorded species (Amphirhachis tertia) from South Korea. New data on the taxonomy and distribution of Amphirhachis tertia are given. We also provide diagnosis and digital images of a newly recorded genus and species.

  • Nepal is a sensitive and disaster-prone country where safety and security risk are of high concern for travelers. Digital technologies can play a vital role in addressing safety and security issues in the country. This research work proposes a Digital tourism security system design for addressing the safety and security issues in tourism industry of Nepal. The study uses Design science research methodology to identify artifacts, interactions, information flow and dependencies between them which are then mapped with existing prevalent technology to provide design solutions. Data is obtained from interview of tourist and experts as a primary source and technical documents/draft, software documentations, surveys as secondary source. Generalized information model, Use cases model, Network architecture model, Layered taxonomy model and Digital tourism technology reference model are the outcomes of the study. The work is very important as it talks specifically about implementation and integration of digital technologies in tourism security governance at federal, provincial, municipal and rural level. The research supplements as a knowledge document for design and implementation of digital tourism security system in practice. As there is very less work on digital systems in tourism security of Nepal, this work is a pioneer and first of its kind.

  • Twenty South Korean tiphiid species are taxonomically reviewed. Among them, Tiphia burrelli is new to Korea. Based on the observation of the holotype, Tiphia seoulensis Tsuneki 1986 is synomymized with T rufomandibulata Smith 1873. Male of T koreana hitherto unknown is newly described. Revised key to species, recognizable characters and digital images are provided. Genital structures of several species hitherto unknown are also given.

  • DASE(Digital TV Application Software Environment)는 데이터 방송을 위한 국제 표준으로 MPEG-2 TS(Moving Picture Experts Group-2 Transport Stream) 형식의 데이터를 처리한다. 소스코드 대신 입력 데이터 명세 정보만을 공개하는 특성상 DASE 시스템의 오류를 테스트하기 위해서는 테스트 데이터에 오류를 삽입하는 방법이 적합하고 이를 위해 MPEG-2 표준을 위한 오류 항목을 개발이 요구된다. 본 논문에서는 관계형 데이터 베이스를 위한 데이터 분류인 Kim’s et al 분류를 근거로 하여 MPEG-2 표준을 위한 오류 항목을 개발하였다. 이는 DASE 시스템의 오류 삽입 테스트 기법에 유용하게 사용될 수 있을 것이다.

  • Pyrgotidae is a small acalyptrate family including about 370 species worldwide and little attention has been given to their systematics until recently. Latest changes in taxonomic status of some of the Korean species made this review inevitable. In the present study, the Korean pyrgotid species are reviewed with discussion of their taxonomic status. We also provide a revised key to all 14 Korean species (seven Adapsilia, three Eupyrgota, two Parageloemyia, one Porpomastix, and one Tephritopyrgota species) supplemented by digital images to facilitate accurate identification.

  • 본 논문은 현재 전자거래에서 폭넓게 활용되고 있는 디지털인증 기술에 대하여 초점을 집중하고 있다. 즉, 현재 다양하게 활용되고 있는 디지털인증 기술들을 체계적으로 분류하기 위한 프레임워크의 개발과 적용 그리고 시사점에 대하여 고찰하였다. 먼저, 본 연구에서는 디지털 인증의 상황적인 흐름을 제공자에서부터 사용자까지 소프트웨어, 하드웨어, 네트워크 측면으로 구분하여 제시하였다. 이어서, 디지털인증의 다섯 가지 구성요소와 주요 요소기술 클래스 그리고 인증유형과 수준에 근거하여 디지털인증 분류 프레임워크를 개발하였다. 본 연구에서 개발된 디지털인증 분류 프레임워크를 베리사인의 디지털 인증 메커니즘에 적용하여 그 유용성을 검증하였다. 실제 사례에 본 연구에서 개발한 디지털인증 분류 프레임워크를 적용한 결과 디지털 인증 기술의 세부적인 분류와 응용을 이해하는데 유효하다는 것을 알 수 있었다. 마지막으로 본 연구의 강점과 약점 그리고 시사점 및 향후 연구 방향에 대하여 논의하였다.

  • 본 연구는 산업현장에서 작업자의 숙련도에 맞추어 학습이 가능한 3D 가시화기술과 이를 바탕으로 하여 자동차 엔진을 구성하고 있는 각각의 부품들 사이의 관계를 설정하고 태스크 온톨로지를 이용하여 자동차 부품을 추천하는 방법을 제안한다. 복합지식을 네트워크 형태의 의미화된 링크와 노드로 구조화하고 3차원 형태로 보여줄 수 있도록 SOM을 이용한 가시화방법을 제안하였다. 또한, is-a Relationship 기반 hierarchical Taxonomy를 이용하여 자동차 엔진을 구성하고 있는 각각의 부품들 사이의 관계를 설정하고, 가중치를 이용한 추천이 이루어 질 수 있도록 하였다. 3D 공간상에 복합지식을 배치하고 사용자에게 제공함으로써 보다 실감적이고 직관적인 네비게이션의 기회를 제공하고, 임의의 자동차 부품을 선택했을 때 해당 부품과 밀접한 관계를 가진 부품을 추천하여 특별한 전문 지식 없이도 손쉽게 자동차 부품의 조립 및 쓰임새와 중요성을 알 수 있게 해준다.

  • In this paper, we propose a methodology to annotate the digital documents through keyphrase extraction using domain specific taxonomy. Limitation of the existing keyphrase extraction algorithms is that output keyphrases may contain irrelevant information along with relevant ones. The quality of the generated keyphrases by the existing approaches does not meet the required level of accuracy. Our proposed approach exploits semantic relationships and hierarchical structure of the classification scheme to filter out irrelevant keyphrases suggested by Keyphrase Extraction Algorithm (KEA++). Our experimental results proved the accuracy of the proposed algorithm through high precision and low recall.

  • In this era of convergence, which is characterized by the integration and combination of technology and industries, broadcasting and communications, offline and online, and devices and services, the content industry is also experiencing rapid changes including inter-genre exchange, the creation of new industries, and customized demand. Specifically, IT-based digital content industries such as the online game, e-book, mobile contents and web portal industries are no longer restricted to the boundaries of video, music and games but are being expanded into the realms of education, medicine, fashion and sports thanks to CT innovation of 3D, CG, AR/VR, VFX, etc. As such, various countries have come to recognize the convergent content industry as a new growth engine that will pick up where the IT industry left off, and are forming policies for its development accordingly. This research aims to optimize the system of content taxonomy which is currently genre-focused and unable to support technological development and convergence, and to discover and select star contents to be rigorously developed with governmental support. In this paper, 20 star contents in 8 areas were selected, and these are expected to create tremendous cultural and economic value through ongoing technological and industrial development.

  • We propose a model-based method for information alignment using educational standards as a case study. Discrepancies and inconsistencies in educational standards across different states/cities hinder the retrieval and sharing of educational resources. Unlike existing educational standards alignment systems that only give binary judgments (either "aligned" or "not-aligned"), our proposed system classifies each pair of educational standard statements in one of seven levels of alignments: Strongly Fully-aligned, Weakly Fully-aligned, Partially-$aligned^{***}$, Partially-$aligned^{**}$, Partially-$aligned^*$, Poorly-aligned, and Not-aligned. Such a 7-level categorization extends the notion of binary alignment and provides a finer-grained system for comparing educational standards that can broaden categories of resource discovery and retrieval. This study continues our previous use of mathematics education as a domain, because of its generally unambiguous concepts. We adopt a materialization pattern (MP) model developed in our earlier work to represent each standard statement as a verb-phrase graph and a noun-phrase graph; we align a pair of statements using graph matching based on Bloom's Taxonomy, WordNet, and taxonomy of mathematics concepts. Our experiments on data sets of mathematics educational standards show that our proposed system can provide alignment results with a high degree of agreement with domain expert's judgments.
