In this paper, we introduce the methodology for the automatic generation of the subject field hierarchy for Intellgent Expert Management Framework using WordNet. Intelligent Expert Management Framework, which is proposed as an appropriate method to manage valuable tacit knowledge within the organization, defines the expert profile structure and proposes the efficient method to automate the process to collect and update the expert profile information based on the profile structure defined. To increase the satisfaction level of users, additional intelligent search features are defined and users can be given the list of experts in related or similar expert fields when they perform expert searches based on the expert database being built. To enable automatic profiling of the organizational experts as well as intelligent expert searches, the subject field hierarchy, upon which the expert profiles are classified and expert searches for similar fields are performed, should be predefined. In this paper, we propose the WordNet library method that first eliminates the ambiguity of the senses of nominal data values, constructs the subject field hierarchy by overlapping the hypernym of the remaining senses, and lastly adjusts the derived hierarchy to the preference of users. Based on the proposed methodology, we expect to avoid the prohibitive costs in building large subject field hierarchies when manually done as well as maintain the objectivity of the hierarchies.

During an investigation of fungi of the order Mucorales from freshwater and sediment samples in Korea, we isolated six strains, NNIBRFG6649, NNIBRFG6255, NNIBRFG1498, CNUFC-YJ13, CNUFC-YR7, and NNIBRFG2739. The morphology and phylogeny of these strains were analyzed. Based on the morphological characteristics and molecular data from internal transcribed spacer (ITS) region, the isolates NNIBRFG6649 and NNIBRFG6255 were identified as Mucor abundans, and M. aligarensis, respectively. The isolates NNIBRFG1498 and CNUFC-YJ13 were identified as M. moelleri, whereas the isolates CNUFC-YR7 and NNIBRFG2739 were identified as M. heterogamus. To the best of our knowledge, M. abundans, M. aligarensis, M. moelleri, and M. heterogamus have not yet been reported in Korea.

The genus Pterosiphonia is composed of 22 species worldwide and four of these species have been reported in the North-East Asia. In Korea, P. pennata originally described from the Mediterranean Sea has been previously recorded from the southern coast as a widespread species. In order to confirm the same species from Korea and Mediterranean, we observed the morphology of Korean Pterosiphonia specimen and analyzed rbcL sequences for inferring phylogenetic relationships among similar congeners. Korean entity was recognized as a new species, Pterosiphonia arenosa sp. nov. The new species is characterized by ecorticate axes with 7-10 pericentral cells, branches formed every two segments, and coalesced with main axis over 1-1.25 axial segments, and tetrasporangia formed in straight series on determinate branches of the upper parts of erect axes. A phylogenetic analysis of rbcL sequences demonstrated that P. arenosa was distinct from P. pennata found in Spain as well as other species. In conclusion, morphological and molecular sequence data indicated that P. arenosa sp. nov. has been previously misidentified as P. pennata in Korea.

Zygnema is a conjugating filamentous green algal genus that is distributed in a broad range of freshwater habitats, from sea level to alpine summits. Although more than 150 species have been described worldwide, their taxonomy remains unclear, probably owing to their relatively simple morphology. We investigated the detailed morphology of Korean Zygnema species, combined with analysis of the plastid psbA gene from 22 specimens of the genus and putative relatives, in order to develope a key to their identification and isolation, and to determine their relationships. We recognized two species of Zygnema; Z. insigne and Z. leiospermum, based on morphological characters such as width of the vegetative cell, position of zygospores, dimensions and form of spores, shape of female gametangia, and color of mesospores. The analysis of psbA data was consistent with morphological comparison. The pairwise divergence between two species was 3.7-4.1% (34-38 bp) in psbA sequences. The phylogeny of psbA revealed the monophyly of Z. insigne and Z. leiospermum together with two isolates of Z. circumcarinatum from Germany and Scotland. This is the first report on the psbA gene phylogeny of Zygnema.

Price is a product attribute, which is determined by the function of the producing cost and profit. It is also identified as one of the most important components of the marketing mix. For consumers, price is an always-existing cue, definite evaluation criteria, and easily accessible information in the purchasing process. Considering the concept of the clothing-price in a comprehensive perspective encompassing economic, psychological and marketing perspectives, a theoretical model was developed. The model includes souses and dimensions of price perception and related behaviors. Souses of price perception were: the actual retail price at selling point, the internal reference price and external reference price. The dimensions of price perception included sacrifice perception, economic value perception, inference, savings perception and price as information perception. Clothing price related behaviors that flowed these dimensions were: low price consciousness, value for money consciousness, price-quality inference, price-prestige inference, sale proneness and price mavenism. An empirical study was conducted to validate the theoretical model. A questionnaire was developed and data were collected from 680 adult women living in Seoul, Korea. Confirmatory factor analysis as well as exploratory factor analysis results showed that theorized price related behaviors were successful classifications.

Taxonomic study of the genus Hemerocallis (Liliaceae) in Korea was conducted based on morphological data. H. middendorffii was distinguished from its related taxon H. dumortieri by the trait of coriaceous long bract with green color. H. taeanensis was distinguished from its related taxon H. minor by its odorless flowers, longer perianth tube and leaf length. H. thunbergii was distinguished from its related taxon H. lilioasphodelus by its long perianth tube. Lastly, H. hakuunensis was distinct from its related taxon H. hongdoensis as a result of its extreme branching of scape and short leaf width. From this study, it was revealed that H. minor, H. lilioasphodelus, and H. dumortieri were distributed only in the northern part of the Korean peninsular.

Microsatellite markers were developed as a tool for phylogeographic studies of Hosta capitata. We also assessed cross-amplification in species closely related to Hosta capitata. We produced 28 polymorphic microsatellite markers by mapping 300 bp paired-end reads obtained from Illumina MiSeq data of H. capitata. In H. capitata, the number of alleles per locus ranged from 1 to 13. Observed and expected heterozygosity ranged from 0.000 to 0.844 and 0.000 to 0.832, respectively. Additionally, 13 loci were successfully transferable to the related species of H. minor and H. venusta. These markers will provide a powerful genetic tool not only for elucidating the phylogeographic patterns of H. capitata populations but also for studying the genetic delimitation of H. capitata from its related species.

In 2012, the NIBR started publishing the Journal of Species Research (JSR) as an international specialized journal of biological taxonomy focusing on taxonomic research. JSR Volume 5 Number 3, to be published in October 2016, has been planned as a 'Special Edition on New and Unrecorded Species of Invertebrates in Korea', and so it consists of the reports of 149 new and unrecorded invertebrate species (including protozoa) discovered in Korea. In future, the JSR should further accelerate the use of such methods to generate valid data for new species and effectively support the compilation of 'National List of Species of Korea'. In this way, it will contribute significantly to enrich for biodiversity in Korea.

Purpose: The purpose of this study was to identify nursing interventions performed by public health nurses in health centers. Method: Data was collected by the taxonomy of Nursing Intervention Classification(NIC 3rd: 486 nursing interventions) from 131 public health nurses in health centers and analyzed using descriptive statistics. Result: As its result, more than 50% of public health nurses performed 137 nursing interventions at least monthly. The most frequently used intervention class was 'activity and exercise management', followed by 'physical comfort promotion', 'community health promotion', 'life span care', 'coping assistance', 'Self care facilitation', 'information management', 'nutrition support', 'community risk management' and 'patient education'. One hundred twenty nursing interventions were rarely performed by 90% or more of the nurses. Most of them were the physical complex domain. Conclusion: In conclusion, 137 interventions were performed by public health nurses at least monthly. NIC is helpful to build a standardized language for public health nursing.

Exhibition industry is important business domains to many countries. Not only lots of countries designated the exhibition industry as tools to stimulate national economics, but also many companies offer millions of service or products to customers. Recommender systems can help visitors navigate through large information spaces of various booths. However, no study before has proposed a methodology for identifying and acquiring prospective visitors although it is important to acquire them. Accordingly, we propose a methodology for identifying, acquiring prospective visitors, and recommending the adequate booth information to their preferences in the exhibition industry. We assume that a visitor will be interested in an exhibition within same class of exhibition taxonomy as exhibition which the visitor already saw. Moreover, we use user-based collaborative filtering in order to recommend personalized booths before exhibition. A prototype recommender system is implemented to evaluate the proposed methodology. Our experiments show that the proposed methodology is better than the item-based CF and have an effect on the choice of exhibition or exhibit booth through automation of word-of-mouth communication.
