The phyllodicd polychaete species, Nereiphylla hera Kato and Mawatari, 1999 is reported from the intertidal habitats of the eastern coast of South Korea. We determined the DNA barcoding region of the mitochondrial cytochrome c oxidase subunit I (COI) of N. hera and compared nucleotide variation with its congeners. The intra-specific genetic distance between the three COI sequences of N. hera was ranged from 0 to 0.4%. The inter-specific distances between N. hera and other Nereiphylla species ranged from 18.8 to 22.3%. In this study, we reported the first COI barcodes of N. hera with the morphologcial diagnosis and the photographs. These results would be helpful to understand taxonomy of Nereiphylla.

Due to the need of data for a Human Reliability Analysis (HRA), a number of data collection efforts have been undertaken in several different organizations. As a part of this effort, a human error analysis that focused on a set of simulator records on a Steam Generator Tube Rupture (SGTR) scenario was performed by using the Human Event Repository and Analysis (HERA) system. This paper summarizes the process and results of the HERA analysis, including discussions about the usability of the HERA system for a human error analysis of simulator data. Five simulated records of an SGTR scenario were analyzed with the HERA analysis process in order to scrutinize the causes and mechanisms of the human related events. From this study, the authors confirmed that the HERA was a serviceable system that can analyze human performance qualitatively from simulator data. It was possible to identify the human related events in the simulator data that affected the system safety not only negatively but also positively. It was also possible to scrutinize the Performance Shaping Factors (PSFs) and the relevant contributory factors with regard to each identified human event.

A newly recorded species, Nereiphylla hera Kato and Mawatari, 1999 which was originally described from northern Japan, was collected from East Sea in Korea. Our Korean materials of N. hera are distinguished from it congeners by the following characteristics that agree well with the original description of the species: the tentacular cirri are flat and spatulate with a narrow and distinct tip, reaching to segment 4-6, and boarder than their cirrophores; the parapodia possess elongated dorsal cirri. We provide a key for distinguishing the species of genus Nereiphylla from Korean waters.

Background: Fish and fishery products (FFPs) unintentionally contaminated with various environmental pollutants are major exposure pathways for humans. To protect human health from the consumption of contaminated FFPs, it is essential to develop a systematic tool for evaluating exposure and risks. Objectives: To regularly, accurately, and quickly evaluate adverse health outcomes due to FFPs contamination, we developed an automated dietary exposure and risk assessment system called HERA (the Human Exposure and Risk Assessment system for chemicals in FFPs). The aim of this study was to develop an overall architecture design and demonstrate the major features of the HERA system. Methods: For the HERA system, the architecture framework consisted of multi-layer stacks from infrastructure to fish exposure and risk assessment layers. To compile different contamination levels and types of seafood consumption datasets, the data models were designed for the classification codes of FFP items, contaminants, and health-based guidance values (HBGVs). A systematic data pipeline for summarizing exposure factors was constructed through down-scaling and preprocessing the 24-hour dietary recalls raw dataset from the Korea National Health and Nutrition Examination Survey (KNAHES). Results: According to the designed data models for the classification codes, we standardized 167 seafood items and 2,741 contaminants. Subsequently, we implemented two major functional workflows: 1) preparation and 2) main process. The HERA system was developed to enable risk assessors to accumulate the concentration databases sustainably and estimate exposure levels for several populations linked to seafood consumption data in KNAHES in a user-friendly manner and in a local PC environment. Conclusions: The HERA system will support policy-makers in making risk management decisions based on a nation-wide risk assessment for FFPs.

The purpose of this study was to examine effects of perceived cosmetic brand personality on the preference of women consumer in 20～30's who started applying adult makeup and were sensitive to cosmetics and makeup techniques to provide domestic cosmetic brands with unique personality marketing resources. A questionnaire developed by researchers was used and 538 questionnaires were used for data analysis. Data was analyzed by SPSS PC(Ver. 16.0). Factor analysis, one-way ANOVA, and muliti regression analysis were done. The findings of this study were; Domestic cosmetic brands' personality factors were aesthetics, performance, interest, competency, and boldness. In case of Isaknox, women consumers in 20-30's preferred it when they perceived its aesthetics, performance, and competency. They preferred Lacvert when they perceived its aesthetics and interest, while they preferred The Face Shop when they perceived its aesthetics, performance, and competency. They preferred domestic cosmetic brand was Hera most, followed by Laneige, Isaknox, Lacvert, and The Face Shop in a descending order. Also they preferred Laneige when they perceived its competency and Hera when they perceived its aesthetics and interest.

This study investigates the effects of three different types of instruction, namely form-based, comprehension-based, and production-based on the development of Korean university students' (n=137) comprehension and production of English relative clauses (RCs). The extent of improvements was analyzed by administering pre-and post-tests consisting of two comprehension tests (selecting the right form of RCs and the right picture descriptions) and one production test (combining two sentences). Findings of this study suggest that all three types of instruction increased participants' comprehension and productions of RCs. However, there appeared differential effects by the instruction type. It was found production-based instruction was most effective in promoting comprehension, followed by comprehension-based instruction. Comprehension-based instruction worked best with the development of production, suggesting that the effects of comprehension training did not only work for increasing comprehension skills, but also transfer to production skills. The type or level of tasks employed for each instruction appeared to play an important role in causing such results. Form-based instruction displayed the lowest improvements in both comprehension and production of RCs. A sentence-combination task employed for form-based instruction appear to result in mere explicit rule explanations without chances to notice rules in context or use their knowledge in practice.

The purpose of this study was to investigate the effects of the hair style, and perceiver's generation on the perception of a high schoolgirl's image. A quasi-experimental method by questionnaire was used. The subjects were 253 high schoolgirls and their mothers living in Jinju. The data were analyzed by using frequency, factor analysis, Cronbach's alpha-reliability coefficient, three-way ANOVA, and Duncan's multiple ranges test. The high schoolgirl's image was derived in five dimensions by factor analysis: schoolgirl look, prettiness, individuality, activeness, and cuteness. In the image based on the hair length, it was assessed that the short cut and the bobbed hair styles looked more like school girls. And the short cut and long hair styles were considered as showing individuality. On the other hand, the bobbed hair style was assessed as cuter than styles of other lengths. For the bangs, the short bangs were found to more school-girl look and cuter than the long bangs. The mother group, whose ages were older than that of the other group, evaluated that the stimulative pictures had more school-girl look, individuality, prettiness, activeness and cuteness, compared to how the school girl group evaluated. It was shown that the generation gap produced different opinions about the stimulative pictures. Therefore hair style, bangs style, and difference in generations were found to be the variables affecting perception of high school girl image.

The prediction skills of stratospheric sudden warming (SSW) events and its impacts on the tropospheric prediction skills in global seasonal forecasting system version 5 (GloSea5), an operating subseasonal-to-seasonal (S2S) model in Korea Meteorological Administration, are examined. The model successfully predicted SSW events with the maximum lead time of 11.8 and 13.2 days in terms of anomaly correlation coefficient (ACC) and mean squared skill score (MSSS), respectively. The prediction skills are mainly determined by phase error of zonal wave-number 1 with a minor contribution of zonal wavenumber 2 error. It is also found that an enhanced prediction of SSW events tends to increase the tropospheric prediction skills. This result suggests that well-resolved stratospheric processes in GloSea5 can improve S2S prediction in the troposphere.

This study investigates how EFL learners' chunking ability both in oral and silent reading affects reading comprehension, and how the chunking ability in silent reading relates to that of oral reading. The participants of this study consisted of 30 Korean university students taking a required 'English Reading' course. Chunking is a technique of grouping words into meaningful syntactic units for better understanding. Chunking was measured from pauses in oral reading. Results of this study suggest that the participants who can chunk properly both orally and silently display better comprehension of texts in general. However, chunking in silent reading was found to be a stronger indicator of improved reading comprehension. Also, the chunking skills in silent reading showed a statistically strong correlation with those observed in oral reading, suggesting that the chunking ability in silent reading may develop in parallel with that of oral reading. Oral as well as silent reading should be continuously practiced to improve reading comprehension of all levels of EFL learners, including low levels of learners. There is also a need to encourage students to read aloud with appropriate prosodic cues to help them read in meaningful units of words, therefore increasing EFL learners' comprehension not only in reading but also in listening.
