  • Whole genome sequence of Abeliophyllum distichum Nakai (Oleaceae) cultivar Ok Hwang 1 Ho, which is Korean endemic species, was recently sequenced to understand its characteristics. Acteoside is one of major useful compounds presenting various activities, and its several proposed biochemical pathways were reviewed and integrated to make precise biochemical pathway. Utilizing MetaPre-AITM which was developed for predicting secondary metabolites based on whole genome with the precise biochemical pathway of acteoside and the InfoBoss Pathway Database, we successfully rescued all enzymes involved in this pathway from the genome sequences, presenting that A. distichum cultivar Ok Hwang 1 Ho may produce acteoside. High-performance liquid chromatography result displayed that callus of A. distichum cultivar Ok Hwang 1 Ho contained acteoside as well as isoacteoside which may be derived from acteoside. Taken together, we successfully showed that MetaPre-AITM can predict secondary metabolite from plant whole genomes. In addition, this method will be efficient to predict secondary metabolites of many plant species because DNA can be analyzed more stability than chemical compounds.

  • An unrecorded Fissidens species, Fissidens protonemaecola Sakurai (Fissidentaceae, Bryophyta), was newly discovered in Korea during an investigation bryophyte flora. In this study, we examined the morphology of F. protonemaecola in Korea. This species was found in soil along a train through a shaded backslope of Mt. Bukbyeongsan (elev. 80 m) on Geojedo Island and on Mt. Gogeunsan (Oreum; elev. 280 m) on Jejudo Island, Korea. This species has dwarfish bud-like shoots scattered on persistent protonemata. An important feature of the protonemata is a diagnostic character of F. protonemaecola that clearly distinguishes it from other Fissidens species. Its Korean name is given as "Cho-rok-sil-bong-hwang-i-kki," inferred from the characteristic protonemata of the species.

  • In this paper, we introduce InfoDID, a robust user information management service based on DID that manages user information reliably. Since blockchain technology provides an environment in which data can be handled transparently on a decentralized basis, various services using blockchain are currently being developed As the importance of user's personal information has recently emerged, the DID technology is receiving attention. The technology allows a user to control his or her information through decentralized identifiers, and various information management services are being tried based on the technology. Using blockchain-based DID technology, InfoDID reliably controls personal information requested frequently, helping users to provide their information to other services more conveniently. In addition, to support service continuity, InfoDID uses BR2K technique that provides robust execution of blockchain application services, so that even partial service failures can be systematically recovered. To facilitate this operation, we present a replication status monitoring tool that can continuously check the replication states of blockchain application services running in association with the BR2K technique such as InfoDID.

  • The national ground survey database (GeoInfo) distributes numerous ground survey data nationwide. Many standard penetration test results exist in this database; however, the number of shear wave velocity (VS) data is small. Hence, to use abundant standard penetration test-N values to predict VS, this study proposed a new empirical N-VS relationship model using GeoInfo data. The proposed N-VS model is a single equation regardless of geological layer types; the layer type only specifies the upper limit of VS. To validate the proposed model, residual analysis was performed using a test dataset that was not used for the model development. Therefore, this study's proposed model performed better than N-VS models from previous studies. Since the N-VS model in this study was developed using sufficient data from GeoInfo, we expect that it is the most applicable to GeoInfo dataset for VS prediction.

  • 본 논문은 날로 증가하는 데이터 처리 요구를 데이터 처리 전용 칩을 이용하여 데이터베이스, 데이터 마이닝, 또는 전문가 시스템 통과 같이 데이터 비교연산에 시간을 많이 소모하는 응용 소프트웨어의 처리 속도를 최소화 할 수 있는 시스템을 제안한다. 본 시스템은 기존의 숫자처리(numeric processing)보다는 기호처리(symbolic processing)를 위해서 관계 연산(relation operation) 모듈을 이용하여 입력된 데이터들을 하드웨어 레벨에서 고속으로 처리한다. 본 시스템은 칩으로 설계되어 하드디스크 레벨에서 시스템을 가속 시린 수도 있고, IP(Intellectual Property)로 구현되어 SoC(System-on-a-chip)의 한 모듈로서 프로세서 레벨에서 시스템을 가속시킬 수도 있다.

  • 문자인식 즉 OCR(Optical Character Recognition)기술은 광학적으로 인식할 수 있는 문자를 컴퓨터가 읽을 수 있도록 하는 기술을 뜻한다. 문자인식의 근간이 되는 방법은 스트링 매칭 기법이 사용되어 왔지만 한글의 경우 자음, 모음, 자음 조합으로 만 가지 유형이 넘고, 더욱이 상용한자와 영어를 섞어 쓰기 때문에 오인식되는 경우가 많다. 본 논문에서는 한글이 수직선, 수평선, 사선과 같이 방향성이 강한 선소들로 구성되어 있다는 점을 이용하여 한글의 인식률을 높이는 방법을 제안하였다.

  • 본 연구를 통해 당구를 처음 접하는 사람들이 혼자서도 올바른 스트로크 자세를 연습할 수 있도록 하기 위한 시스템을 설계하였다. 6 축 자이로 센서를 활용하여 가속도, 각속도 센서 값을 안드로이드와 BLE 통신으로 수집하고 그 값으로 스트로크의 속도와 각도, 방향을 계산하여 유사율을 나타낸다. 또한 터치센서에 스트로크 시에 타격감을 주기 위하여 모바일의 진동을 울려주며, 센서에 터치 된 값을 이용하여 사용자가 실제 타격한 당구공의 타점을 모바일에서 실시간으로 보여준다. 동시에 앞서 계산된 유사율을 그래프와 수치상으로 확인할 수 있다. 모범 자세와 비교한 피드백을 통하여 올바른 스트로크 자세를 익힐 수 있도록 도와준다.
