The storage and retrieval of multimedia data is becoming increasingly important in many application areas including record management, video(CCTV) management and Internet of Things (IoT). In these applications, the files containing multimedia that need to be stored and managed is tremendous and constantly scaling. In this paper, we propose a technique to retrieve a very large number of files, in multimedia format, using the Hadoop Framework. Our strategy is based on the management of metadata that describes the characteristic of files that are stored in Hadoop Distributed File System (HDFS). The metadata schema is represented in Hbase and looked up using SQL On Hadoop (Hive, Tajo). Both the Hbase, Hive and Tajo are part of the Hadoop Ecosystem. Preliminary experiment on multimedia data files stored in HDFS shows the viability of the proposed strategy.

Two specimens of Taractes rubescens (family Bramidea) were collected from Busan and Pohang, Korea, between 2015 and 2016. Taractes rubescens was very similar to Taractes asper, but the two species are clearly distinguishable by the number of anal fin rays (21-23 in T. rubescens vs. 25-27 in T. asper) and the presence of a lateral caudal keel (present in T. rubescens vs. absent in T. asper). The mitochondrial DNA cytochrome c oxidase subunit I sequences of the specimens described in this paper perfectly matched those of T. rubescens, but differed from those of T. asper (genetic distance: 6.9%). We use the Korean common name proposed by Kim and Ryu (2017) for T. rubescens, "Geom-eun-sae-da-rae".

Automation can help organisations implement authentic and reliable record management practices, through the improved tracking of records through their life cycle as well as the consistent application of records schedules and descriptive standards. Maintaining evidence through authentic and reliable records is a cornerstone of good business practice and helps ensure a valuable record for society. This paper provided understanding of establishing records and archives management system(ARMS) with the case of the Jogye order of Korean buddhism. This system was designed to control records in the whole step from creation to preservation so that it automatized process to organize and control current records and to preserve archives. This system covers a wide range of archival functions including appraisal, arrangement and description, transfers, access, location and space management, microfilm management and destruction. This system will be applied records management of similar organization because of designing from the archival scientific point of view. Also, development process of this system will help archivist to build ARMS based on archival needs of institution.

SNOMED CT is a standard clinical terminology which is to efficiently record, manage and utilize clinical records during clinical processes. However, huge expressive power of SNOMED CT makes it difficult to select appropriate terms during short consultation hours. In addition, true meaning of a written record using the terminology may be misunderstood or even distorted since one clinical meaning could be expressed in a variety of ways. This paper analyzes such known problems in a database point of view, and presents effective selection methods of similar terminologies to mitigate the problem.

In the digital environment, electronic records are explosively increasing, but there are little concerns on how to effectively manage and service. On-Nara 2.0 and record management system, the information system of records production and management stage, are being developed and distributed on the cloud base. Archives management system requires the acquisition of new record management techniques because they need to acquire and manage various types of private records as well as public records. In this paper, we will discuss automation and intelligent technologies for archives management.

In this paper, we propose an algorthm for ensuring patient anonymity based on block chaining. For the anonymity of the patient and the inability to connect between the doctor and the patient, we used the stealth address separately from the identification address. Also in using the medical record, the use information such as the hash value is inputted into the block to guarantee the integrity and transparency of the medical record.

An epialtid spider crab, Naxioides robillardi (Miers, 1882), is known as widely distributed in Indo-West Pacific region include Japanese waters. Four specimens of epialtid crabs were collected from adjacent waters of Jejudo Island and identified as N. robillardi. This species can be grouped into two forms such as N. robillardi form typical and N. robillardi form mammillata according to morphological features of carapace, gastric spine, and chela. Morphological characters of all Korean specimens well agree with the form mammillata in general. In this paper, morphological diagnosis and illustrations of newly collected N. robillardi are provided. DNA barcode sequence of COI region is also determined for the first time.

A hesionid species, Leocratides kimuraorum Jimi, Tanaka and Kajihara, 2017 is newly reported from the sublittoral zones (100 m depth) of the Korean coasts. This species is characterized by lateral antennae as long as the palps, peristomial membrane without papillose, peristomial dorsolateral tubercles with two round marginal lobes, and pharyngeal with terminal papillae. The intra-specific genetic distance among the cytochrome c oxidase subunit I(COI) sequences of L. kimuraorum specimens from Japan (type locality) and Korea (this study) was in the range of 0.002-0.005. The inter-specific genetic distance between L. kimuraorum and other hesionid species were 0.166-0.307. The present study is the first record of Leocratides species in Korean fauna. This paper also provides a morphological description and photographs of L. kimuraorum, with partial sequences of the mitochondrial COI based on Korean specimens.

This paper develops a comparatively time-efficient methodology for performing seismic fragility analysis of the reinforced concrete (RC) buildings in the presence of uncertainty sources. It aims to appraise the effectiveness of any variation in the material's mechanical properties as epistemic uncertainty, and the record-to-record variation as aleatory uncertainty in structural response. In this respect, the fuzzy set theory, a well-known 𝛼-cut approach, and the Genetic Algorithm (GA) assess the median of collapse fragility curves as a fuzzy response. GA is requisite for searching the maxima and minima of the objective function (median fragility herein) in each membership degree, 𝛼. As this is a complicated and time-consuming process, the authors propose utilizing the Gene Expression Programming-based (GEP-based) equation for reducing the computational analysis time of the case study building significantly. The results indicate that the proposed structural analysis algorithm on the derived GEP model is able to compute the fuzzy median fragility about 33.3% faster, with errors less than 1%.

Xylophagids are a small group of dipterans with 133 known species worldwide except for in the Afrotropical region; they are composed of three subfamilies: Coenomyiinae, Rachicerinae and Xylophaginae. Their larvae are predatory and tend to be found under bark, soil or decaying wood. Hitherto, the following five species in three genera of Xylophagidae have been recorded in Korea: Anacanthaspis japonica Shiraki, Arthropeas sachalinensis Matsumura, Ar. sibirica Loew, Odontosabula czerskii (Pleske) and O. gloriosa Matsumura. In this paper, the awl fly genus Xylophagus Meigen, 1803 is reported from the Korean peninsula for the first time, based on the discovery of a newly recorded species, Xylophagus matsumurai Miyatake, 1965. Descriptions, illustrations of this previously unrecorded species and a key to the Korean species are provided herein.
