This study aimed to identify the differences in pitch perception between tonal and non-tonal language listeners. A total of 60 Korean and Chinese listeners participated in the perception test. A two-syllable nonsense word /paba/ was manipulated in five steps. The pitch height or contour on the second syllable was raised or lowered. Both groups were asked to select which of the two syllables had the higher pitch. The findings showed that the majority of Korean listeners (GK) perceived decreased pitch as each peak of the syllable was lowered and perceived increased pitch as it was raised, which means the pitch height is a primary perceptual cue for GK. However, Chinese listeners (GC) perceived sensitive pitch movements as the pitch contour changed. GC's perception may presumably be affected by the L1's tone sandhi. We found it reasonable to assume that language experience has a significant effect on the cross-linguistic perceptual differences between tone and non-tonal language listeners.

In Jamaica Kincaid's novel Lucy, the narrator grows up with the burden of colonial legacies embedded with Englands' imperial disciplinary projects, its language, educational institutions, discourses. Colonial education interpellates the narrator into a colonial subject through its multiple ideological discourses and systems. Teaching the literature of England is the most insidious form of the Empire's disciplinary colonial projects, more powerful than military enforcement: Its mode of operation is creating phantasy and instigating and planting desire for such phantasy. As Homi Bhabha aptly theorizes as colonial mimicry and ambivalence, the narrator as colonial subject grows up split and confused as an ambivalent subject, simultaneously mimicking and desiring for the phantasized England as real, while resisting and criticizing such up-bringing and mimetic desire. This paper explores Kincaid's rhetorical strategy of employing Wordsworth's poem, "I Wandered as a Lonely Cloud," especially her use of the flower "daffodil." Employing the concept of "daffodil gap" suggested by postcolonial critics, this paper closely examines two episodes involving the flower daffodil in the novel, one in a colonial classroom and the other in a garden in a new world and suggests that Kincaid accomplishes intertextual critique of colonial education and imperial projects.

We're living in a world of one global village. The globalization of business is acceleration as more companies cross national borders to find customers, materials and money. Many foreign companies and organizations are doing their business aggressively in Korea and many Korean companies and rushing into foreign market. When people communicate for business with someone from another culture, there could be difficult communication barriers to overcome resulting from differences in their values, beliefs, norms for behavior, expectations, attitudes and so on. To do successfully business, we need to understand culture background and communication style that is different from nation, race, language. Communication barriers stemming from cultural differences may vary. Largely, they can be divided into value system, non-verbal communication, and perception process. Value system can be divided into individualism versus group orientation, avoidance of uncertainty degree, power distance, and high- context culture versus low-context culture. Also non-verbal communication method and perception process may play decisive roles in communication effectiveness. Especially nonverbal communication barriers which sometimes play more important roles than the verbal parts are composed of eye contact, gesture, kinesics, proxemics, chronemics, paralanguage and language of color Cross-cultural communication affect business situation. I expect that if we understand cultural background, and then we overcome cross-cultural communication barriers. To overcome and to adapt inter-cultural business, we need to develope curriculum on the cross-cultural education which I will study in the next paper.

We have calculated the reaction probability and the reaction cross-section of the $N(^4S)+O_2(X^3\sum_{g}^{-})\;\rightarrow\;NO(X^2\Pi)+O(^3P)$ reaction by the quasiclassical trajectory method with the 6th-order explicit symplectic algorithm, based on a new ground potential energy surface. The advantage of the 6th-order explicit symplectic algorithm, conserving both the total energy and the total angular momentum of the reaction system during the numerical integration of canonical equations, has firstly analyzed in this work, which make the calculation of the reaction probability more reliable. The variation of the reaction probability with the impact parameter and the influence of the relative translational energy on the reaction cross-section of the reaction have been discussed in detail. And the fact is found by the comparison that the reaction probability and the reaction cross-section of the reaction estimated in this work are more reasonable than the theoretical ones determined by Gilibert et al.

Purpose: The objective of this study was to identify the effects of problem based learning (PBL) combined with simulation on the basic nursing competency of nursing students. Method: A pretest-posttest design with a nonequivalent control group was used to examine the effects of problem based learning combined with simulation for 9 weeks in a group of 283 nursing students. The PBL group of 141 students participated in PBL classes with simulation, 4 hours a week for 9 weeks compared to control group of 142 students who received the usual fundamental nursing class. Results: The group that had PBL with simulation showed significant increases in problem solving and self-directed learning competency, although there were no significant changes in communication competency as compared to the control group. Conclusion: The findings of this study demonstrate that PBL with simulation for nursing students may increase problem solving and self-directed learning competency and suggest that utilizing this teaching-learning method may be beneficial as an effective nursing education strategy.

Recently, continuous dimensional emotion recognition from audiovisual clues has attracted increasing attention in both theory and in practice. The large amount of data involved in the recognition processing decreases the efficiency of most bimodal information fusion algorithms. A novel algorithm, namely the incomplete Cholesky decomposition based kernel cross factor analysis (ICDKCFA), is presented and employed for continuous dimensional audiovisual emotion recognition, in this paper. After the ICDKCFA feature transformation, two basic fusion strategies, namely feature-level fusion and decision-level fusion, are explored to combine the transformed visual and audio features for emotion recognition. Finally, extensive experiments are conducted to evaluate the ICDKCFA approach on the AVEC 2016 Multimodal Affect Recognition Sub-Challenge dataset. The experimental results show that the ICDKCFA method has a higher speed than the original kernel cross factor analysis with the comparable performance. Moreover, the ICDKCFA method achieves a better performance than other common information fusion methods, such as the Canonical correlation analysis, kernel canonical correlation analysis and cross-modal factor analysis based fusion methods.

The objective of this study was to improve the cross-sectional area and height estimation method using stream width. Stream water levels should be calculated together to simulate inundation of agricultural land. However, cross-sectional survey data of small rural rivers are insufficient. The previous study has developed regression equations between the width and the cross-sectional area and between the width and the height of stream cross-section, but can not be applied to a wide range of stream widths. In this study, cross-sectional survey data of 6 streams (Doowol, Chungmi, Jiseok, Gam, Wonpyeong, and Bokha stream) were collected and divided into upstream, midstream and downstream considering the locations of cross-sections. The regression equations were estimated using the complete data. $R^2$ between the stream width and cross-sectional area was 0.96, and $R^2$ between width and height was 0.81. The regression equations were also estimated using divided data for upstream, midstream and downstream considering the locations of cross-sections. The range of $R^2$ between the stream width and cross-sectional area was 0.86 - 0.91, and the range of $R^2$ between width and height was 0.79 ? 0.92. As a result of estimating the cross-sections of 6 rivers using the regression equations, the regression equations considering the locations of cross-sections showed better performance both in the cross-sectional area and height estimation than the regression equations estimated using the complete data. Hydrologic Engineering Center - River Analysis System (HEC-RAS) was used to simulate the flood stage analysis of the estimated and the measured cross-sections for 50-year, 100-year, and 200-year frequency floods. As a result of flood stage analysis, the regression equations considering the locations of cross-sections also showed better performance than the regression equations estimated using the complete data. Future research would be needed to consider the factors affecting the cross-sectional shape such as river slope and average flow velocity. This study can be useful for inundation simulation of agricultural land adjacent to an unmeasured stream.

The purpose of this study was to investigate the effect of leg extension exercises performed on outdoor resistance exercise machines on knee extension muscle strength and quadriceps muscle group cross sectional area (CSA) in elderly women. Two groups were recruited for this study, including an exercise group (EG: n=13, $71.38{\pm}2.79$ yrs) and a control group (CG: n=5, $73.4{\pm}5.94$), In all subjects, maximum isometric and isokinetic muscle strength of knee flexion and extension were measured using an isokinetic dynamometer (Cybex(R) Humac Norm Testing & Rehabilitation System, USA). Quadriceps muscle group CSA were measured using MRI (Philps, Intera 1.5 T, NE Netherlands). The results of this study showed that post-intervention isometric knee extension peak torque value were higher than pre-intervention measures in the EG. However, the EG did not show improvement in quadriceps muscle group CSA, Also, no differences in the shift of optimal knee joint angle were observed between pre and post-intervention exercise. Outdoor leg extension exercise showed small increases in muscle strength in comparison to other resistance training exercises. The results of this study suggest that because outdoor leg extension exercise machines lack a progressive loading mechanism, significant increases in muscle strength may not be obtained.

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.

Purpose: This study is aimed at preparing basic data to increase professionalism in nursing and effective counter-strategies against future infectious diseases. For that purpose, this study investigated the experiences of nurses in a general hospital with an 800-bed size, temporarily closed after a confirmed case of COVID-19. Methods: This study was a qualitative study using individual in-depth interviews, and data were collected from 10 nurses in a university hospital temporarily closed from May 1 to June 13, 2020. Results: As a result of this study, the subjects were classified into 'COVID-19 and nursing', 'nursing work and vocation' and 'life changed with COVID-19'. Conclusion: In conclusion, there is a need for education that nurtures the ability of nurses to screen patients with infectious diseases well and to skillfully wear and remove protective clothing. In addition, in order to cultivate the expertise of nurses and respond efficiently to infectious diseases, a separate compensation, such as a risk allowance, is required along with the establishment of an infrastructure that fully supports personnel and supplies. A mental health program to relieve stress is also required.
