The mugilidae fishes are common euryhaline species that live in coastal marine waters to freshwater areas. The taxonomy and nomenclature of the mugilidae fishes still remain unresolved because of their morphological similarities. Among the mugilidae fishes, most commonly consumed in Korea, are grey mullet (Mugil cephalus) and red lip mullet (Chelon haematocheilus). It is generally called 'mullet' without distinguishing between two mullets. Therefore, the aim of this study is to examine the scientific names and common names of mullet species used in Korea from the domestic journals and Korean old documents. The scientific name of grey mullet is M. cephalus, but that of redlip mullet is C. haematocheilus. But the genus of redlip mullet is still mixed with Chelon, Mugil, and Liza. The standard name of two mullet is not distinguished in the Korean dictionary, but they were clearly distinguished in the Japanese, English, and Chinese dictionaries. In the ancient Korean references, the mullet was called 'Chieo' or 'Sueo'. In most of the old literature, the distinction between grey mullet and redlip mullet is not clear. However, in Jasaneobo, it was written separately from grey mullet and redlip mullet, and attaching "ga" was different from now. The Korean standard name of redlip mullet is 'gasungeo', however, the fishermen in Jeollado and Gyoungsangdo call it 'chamsungeo'. Considering the negative perception of 'ga' character, it is proposed to change 'cham(眞)' instead of 'ga(假)' to improve economic value of red lip mullet.

The purposes of this study are to summarize the past studies on human resource management (HRM) published in Asia Pacific Journal of Small Business and to propose the future research directions. This study selected 33 HRM papers (3.1 % of all published papers) and classified them depending three yardsticks. First, this study investigated the frequency and the trend of each year and, as a result, it demonstrated the variations in published papers depending on the publication year. Next, on the basis of the research theme, this study divided 33 papers into two parts; a general HRM vs. a specific HRM practice. The result showed that most studies focused on the specific HRM practice. Lastly, with regard to methodology, this study classified them into a conceptual paper, a case-study, and empirical research, and the result showed that most studies are empirical-based papers. Based on the trends, this study proposed three issues in terms of the number of research, research theme, and methodology, and suggested future research directions for HRM in small-medium enterprises.

This study explores differential value implications of R&D expenditure across firms, especially in terms of growth potential of small businesses. Analyzing Korean listed firms for the period from 1982 to 2014, we document the followings. First, large firms, defined as the top quintile group based on market capitalization, have spent higher R&D expenditure compared to small (bottom quintile group) and medium (middle quintile groups) firms and the difference between groups has enlarged over time. Relatedly, the persistence of R&D spending, measured by the association between current R&D expenditure and cumulative future R&D expenditure over the next five years, is lowest in small firms. Second, R&D of large (small) firms are more (less) likely to generate operating profits over the next five years. Additional analyses suggest that the relation between R&D and gross margin is strongest in large firms, suggesting that R&D underlies their competitiveness in the product market. Third, small firms have borne the highest uncertainty related to R&D investment proxied by the association between current R&D and volatility of future earnings. As a result, the likelihood of R&D leading to future patents is also lowest in small firms. Fourth, the probability of moving up to the next size group within the next five years is significantly lower in small firms than others. Finally, we find that the divergence in R&D expenditure between large and small firms is positively associated with product market concentration. Overall, our findings confirm the small business growth trap in relation to R&D investment.

Organization and management scholars have researched social enterprises as hybrid organizations. However, research on the organizational uniqueness of social enterprises as hybrids is limited, especially comparing their organizational characteristics with other traditional types of organizations. Thus, this study attempted to compare social enterprises with traditional for-profit and not-for-profit organizations in the aspect of their organizational hybridity by using the data of the Social Value Survey. The results showed that the orientation of social enterprises in pursuing dual values is weaker than the other two types of organizations. Meanwhile, the results revealed that the extent to which an organization operates for realizing dual values is strongest in social enterprises among the three types of organizations. These findings add to the understanding of social enterprises' organizational hybridity in organization and management studies.

This study examines the concentration in terms of supply and consumption in the Korean movie market, focusing on screen size, nationality, and the box office. For analysis, it selects the top 100 movies in the box office each year for 15 years from 2005 to 2019. According to the result, the number of screens increased steadily every year, and the screen concentration became very high. For the top 100 movies, it increased from 12% to 30% of the total screen. It became higher in the case of the top 10 movies. As the number of screens increased, multiplex assigned more screens to one movie. Multiplex's screen allocation continued to increase, with one movie taking up more 60% of the total screen. This became more serious after 2011 and 2012. Market share of the top 100 movies accounted for about 95% of the total box office performance, even though the number of released movies is about 3,000. Whether multiplex preferred Hollywood movies or not, its screen assignment was found to favor Hollywood movies over Korean ones. In the case of film nationality, both Korean and Hollywood movies accounted for 90.7%. Two countries had a market share of 96.6%. There was no single side except Korea and the United States in the top 10. The increase in the number of screens deepened the concentration in screen allocation. The concentration in the screen allocation led to the concentration of consumption. The Korean film market is the case where the increase of movie screens did not create a diversity of supply and consumption. It also did not affect the diversity of film nationality. This research reveals that supplied concentration and consumed concentration are positively correlated, and that the former is a little lower than the latter.

With the increasing number of skin care shops, service quality development that can meet the customer needs is needed to obtain differentiated competitive advantage. Accordingly this study was attempted to provide basic data on marketing necessary for operating a skin care shop by identifying the impact of service quality on perceived reciprocity and long-term relationship orientation among the customers using a skin care shop. This study conducted a survey of 290 female customers using skin care shops located in Seoul and Gyeonggi province, Jeollanamdo and Jeollabukdo, and Gyeongsangnamdo and Gyeongsangbukdo through personal visit, e-mail, and post service, and the collected data were analyzed with SPSS Ver. 18.0 and Amos Ver. 18.0. As a result, it was proven that overall goodness-of-fit to the theoretical model of the research hypotheses set in this study is good. In Hypothesis 1, "Skin care specialist's work ability, facility and sanitation, and care products had a significant positive (+) impact on perceived reciprocity," which was partially adopted. In Hypothesis 2, "Skin care specialist's work ability, care products, and devices and tools had a significant positive (+) impact on long-term relationship orientation," which was adopted. In Hypothesis 3, "Perceived reciprocity had a significant positive (+) impact on long-term relationship orientation," which was adopted. Therefore, it can be concluded that skin care specialist's work ability, facility and sanitation, care products, and devices and tools are the service quality elements for allowing customers to feel thankful or encouraging them to visit the skin care shops continuously.

This research aims to review the training systems and curriculums of early childhood educators in Korea and France and seek directions to improve teachers training in Korea. To achieve the research purpose, this article compares three criteria, namely teacher training institutes, training systems, and curriculums based on the legal systems of Korea and France. Below are the summaries of the comparison. First, the training for teachers in France is carried out by the INSPÉ, the state-level single training system, for those who have bachelor's degrees. Second, the second year INSPÉ students or preliminary teachers take national teacher qualification tests. If they pass the tests, they are sent to the teaching fields as licensed teachers. Third, there are 3-year scholarship programs and support for practicums as part of the INSPÉ curriculum through the teacher support system in France to select highly qualified teachers. Fourth, the French curriculums prioritize basic knowledge skills, integration of school systems, teaching practicum experiences that are tied to the teaching fields, and research and analysis of practicum experiences.

Objectives : This study investigated anti-inflammatory effects of Nardotidis seu Sulculii Concha water extract (NSCE) against restraint-induced stress. Methods : In vivo, NSCE was orally administered to male white mice at concentrations of 250 mg/kg and 500 mg/kg for 3 days, and then restraint-induced stress was induced for 6 hours. The level of liver damage was measured by serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH). The stress-related hormones such as cortisol and corticosterone were measured by ELISA assay. Also, western blot analysis was performed to detect expression of mitogen-activated protein kinase (MAPK) and cyclooxygenase-2 (COX-2) proteins. Pathological changes were observed by hematoxylin and eosin (H&E) staining of the liver tissue, and Immunohistochemical (IHC) staining was performed to examine liver inflammation through macrophage infiltration. Results : The AST, ALT, LDH and the stress related hormones such as cortisol and corticosterone were significantly decreased in the NSCE treated group compared with stress group. In histological analysis, H&E staining of liver tissues did not detect the hepatic injury or damage in all groups. As a result of IHC staining, it was confirmed that infiltration of macrophages was increased in the stress-induced group, but decreased in the group treated with NSCE. The COX-2 and MAPK proteins expression was significantly increased by restraint-induced stress, but these proteins were decreased in the NSCE treated group. Conclusions : These results suggest that NSCE has the anti-inflammatory activity in restraint-induced stress model, and it is believed that NSCE can be used for the prevention of liver inflammation.

In this study, a fin that controls ship stern flow was attached on stern hull of a 80k bulk carrier to improve resistance performance. The rectangular cross-sectional fin was attached at several locations on the hull, and angle to streamline was changed with constant length, breadth, and thickness. The resistance performance and wake on propeller plane of the hull with and without the fin were analyzed using model-scale computational fluid dynamics simulation. The analysis results were extrapolated to full-scale to compare the performance and wake of the full-scale ship. First, the fin changed path of bilge vortex that flowed into the propeller along the stern hull without the fin to transom stern. This change increased pressure of the stern hull and upper region of the propeller, so pressure resistance and total resistance of the hull were reduced - the nearer the fin location to after perpendicular (AP) and base line of the hull, the larger the reduction of the resistances. Second, nominal wake fraction of the hull with the fin was lower than that without the fin. This dif erence was in proportion to the angle of the fin, but the total resistance reduction was in proportion until a certain angle at which the reduction was maximum. The largest total resistance reduction was approximately 2.1% at 12.5% of length between perpendiculars from the AP, 10% of draft from the base line, and 14° with respect to the streamline.

Purpose: The purpose of this study was to apply patient-engaged bedside handoffs in comprehensive care units, and to evaluate the effects of bedsides to nurses and patients. Methods: This study employed a cluster randomized cross-over design.Electrical Medical Record (EMR)-based handoffs and patient-engaged bedside handoffs were alternatively applied to 104 patients, who were assigned to a total of 30 clusters (nursing handoff teams) in 4 comprehensive care units at the S medical center in Seoul, and the patients evaluated each type of handoffs. A total of 139 nurses were also participated in the same units and evaluated each type of handoffs. Data were analyzed using t-test, Wilcoxon rank sum test, ANOVA, and Kruskal-Walls test. Results: The patient's satisfaction of the patient-engaged bedside handoffs was higher than that of the EMR-based handoffs (Z=-5.16, p<.001). On the other hand, the nurse's satisfaction of the patient-engaged bedside handoffs was significantly lower than that of the EMR-based handoffs (t=13.21, p<.001). There were no differences in length of the reporting time between two types of handoffs (t=-0.48, p=.634). Conclusion: Patient satisfaction with the patient-engaged bedside handoffs was higher than that of EMR-based handoffs, and nurses' satisfaction with the patient-engaged bedside handoffs was significantly lower than that of EMR-based handoffs. Future studies are needed regarding the impacts of patient-engaged bedside handoffs on the quality of healthcare by identifying the benefits of the handoffs.
