In order to secure basic data on biodiversity for wetland conservation and management used the data from Wetland Protected Area surveys conducted in South Korea (2015-2019) to analyze the distribution of fish from a total of 15 orders, 45 families, 134 species, and 12,972 individuals. The predominant species identified were Zacco platypus (Temminck and Schlegel) (19.47%) and Zacco koreanus (Kim, Oh and Hosoya) (8.16%). Of all emergent species, 52.9% (n=71 species) were freshwater species, 26.9% (n=36) were brackish species, 3.0% (n=4) were migratory species, 27% (n=36) were marine species, and 9.0% (n=12) were riffle benthic species. Overall, 5.2% (n=7 species) were endangered species, 3.0% (n=4) were exotic species, and 23.1% (n=31) were Korean endemic species. The eight identified Wetland Protected Areas (WPA) were classified based on their habitat characteristics and on the analysis of their emergent fish communities, as estuarine (n=2), coastal dune (n=1), marsh (n=2), stream (n=2), and stream-marsh (n=1) types. The environmental factors revealed to have the greatest influence on the species diversity of emergent fish were maintenance and repair, installation of reservoirs, and construction of artificial wetlands around them. The present study offers basic information on the diversity of fish species in different Wetland Protected Area types that can be used to inform conservation and management decisions for WPA.

IT projects need engineers with various backgrounds to cooperate to build an IT system that satisfy the requirements of users given a limited expense and time. Such diversity of team members and the complexity of task naturally involve considerable amount of conflict among team members. High level of conflict among team members is known to be detrimental to the performance of the team. The purpose of this study is to examine the reasons for conflicts among team members in IT projects and to check how the level of conflict affects the performance of a project and the satisfaction of the members of the project team. To test the relationship, a survey on 166 participants in IT projects was conducted. The reasons for conflicts in IT projects were categorized into five types. The level of ambiguity was found to have a significant correlation with the level of conflict. And the level of conflict, in turn, is found to have a significant effect on the degree of satisfaction among team members and the project results. Based on the research results, it is suggested that a clear definition of tasks and their boundaries is required to reduce ambiguity and thus, the level of conflict and improve the level of satisfaction of IT project team members.

Purpose - Diversity subject is rising globally, as the proportion of women in the workforce increased to a large extent and the variety of resources became greater. Diversity attempts have appealed more awareness to the value of female participation in various areas, notably in the boardroom and corporate governance. This study tests the relationships among gender diversity, openness, and innovation, at the firm level across countries from the MOI Survey. Research design, data, and methodology - In this study the relationships among gender diversity, openness, and innovation were investigated at the firm level across countries from the Management, Organisation, and Innovation (MOI) Survey. A cross-cultural analysis was conducted based on the empirical evidence from six countries: Germany, India, Lithuania, Poland, Romania, and Russia. Result - The results show that gender diversity is positively related to innovation performance, moreover openness is positively associated with the level of firm innovation. In addition, a company's capability to use knowledge from outside and the creation of new combinations positively influence a firm's potential to innovate. Conclusion - This study suggests that the more gender-diverse top management team and the higher openness may bring the firm's innovation with greater possibility. the paper encourages more female participation on top management on the grounds of recommending that firms with greater gender diverse top management teams.

Background: Inner Mongolia, desertification is happening due to climate change and land use alterations. In order to evaluate desert restoration effectiveness, this study compares number of species and species diversity in restored (with planted trees), unrestored area, and the reference ecosystem (Ref-E, typical steppe and woody steppe). Results: The Ref-E had the most plant species (64 taxa), while the unrestored area had the fewest (5 taxa). Among restored areas (restored in 2012, 2008, 2005), older restoration sites had more species (18-42). Similarly, species richness (3.93-0.41) and diversity (1.99-0.40) were highest in the Ref-E and lowest in unrestored areas, with older restored sites having higher values. Conclusions: More plant species and diversity in older restoration areas suggest progress toward ecosystem stabilization, approaching the Ref-E. Therefore, tree planting in Inner Mongolia's Hulunbuir semi-arid desert is a successful restoration effort.

Work engagement and job burnout are crucial problems in Korea, particularly in the business environment, and they also indicate people's motivation. Online-based teams in e-business also have these issues. Especially the role of the leader in this new type of teams is more crucial for members' motivation, behavior, and performance. Contingency leadership theories posit that different situations need different traits or behaviors of a leader. For an online-based team, which is internet-based team in e-business, a leader should use specific communication strategies to enhance a team's performance and members' motivation. In an online-based team and an offline-based team, the ways in which leaders motivate members will be different. This paper suggests particular communicative strategies for leaders of online situations. Online-based team members communicate using mobile phones or IT tools, and leaders mayinfluences members in virtual meetings. Moreover, online-based leadership needs to be more entrepreneurial and risk encouraging, and less conservative than offline-based leadership. In addition, online-based leadership should be energetic, decisive, adaptable, and inspiring, and furtherutilize communication tools such as being more gregarious/talkative, assertiveness, linguistic diversity and affect. This paper explains the roles of communicative elements such as coordination, expression, direction-giving/uncertainty reduction, empathy, meaning-making, satisfaction, and competence to decrease job burnout and to increase work engagement. The purpose of this study is to suggest communication strategies' differentiated influences on work engagement and job burnout in an online-based team.

We evaluated the influence of sampling technique (cannulation vs. stomach tube) and site (dorsal sac vs. ventral sac) on the rumen microbiome and fermentation parameters in Hanwoo steers. Rumen samples were collected from three cannulated Hanwoo steers via both a stomach tube and cannulation, and 16S rRNA gene amplicons were sequenced on the MiSeq platform to investigate the rumen microbiome composition among samples obtained via 1) the stomach tube, 2) dorsal sac via rumen cannulation, and 3) ventral sac via rumen cannulation. A total of 722,001 high-quality 16S rRNA gene sequences were obtained from the three groups and subjected to phylogenetic analysis. There was no significant difference in the composition of the major taxa or alpha diversity among the three groups (p>0.05). Bacteroidetes and Firmicutes represented the first and second most dominant phyla, respectively, and their abundances did not differ among the three groups (p>0.05). Beta diversity principal coordinate analysis also did not separate the rumen microbiome based on the three sample groups. Moreover, there was no effect of sampling site or method on fermentation parameters, including pH and volatile fatty acids (p>0.05). Overall, this study demonstrates that the rumen microbiome and fermentation parameters are not affected by different sampling techniques and sampling sites. Therefore, a stomach tube can be a feasible alternative method to collect representative rumen samples rather than the standard and more invasive method of rumen cannulation in Hanwoo steers.

단일민족으로 오랫동안 지내왔던 한국사회의 구성원들이 급속하게 다양화되면서 앞으로 한국 조직 내 인적자원관리에서 다양성이 차지하는 비중은 늘어날 것이다. 본 연구에서는 한국노동연구원 사업체패널자료를 활용하여 다양성 친화적인 인적자원관리가 조직의 인력구성에 미치는 영향을 분석하였다. 실증분석에 따른 주요결과들로는 여성인력에 대한 훈련비중이 높으면 여성인력 구성비율이 증가되며, 임금에서 이익분배와 집단성과급제도가 차지하는 비중이 높은 기업은 장애인 비율이 높고, 다수의 모집제도를 활용하는 기업에서는 외국인 근로자 비율이 증가하는 것으로 나타났다. 하지만 인력다양성 확대를 억제할 가능성이 있는 인적자원관리제도(핵심인력관리제, 연봉제, 인사고과제)에 비하여 다양성 친화형 인적자원관리제도는 기업의 재무성과에 유의한 영향을 미치지 못하는 것으로 나타났다. 따라서 기업은 처해진 경영상황과 조직문화에 따라 인력구조의 다양성과 경쟁력을 효과적으로 관리하는 인적자원관리제도를 구상하여야 할 것이다. 본 연구는 다양성 친화형 인적자원관리제도를 형성하는데 있어서 경영성과에 근거하여 주요 세부제도들이 어떻게 효과적으로 형성되어야 할 것인지에 대한 시사점을 주는데 의의가 있다.
