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.

Background: Though the biomass of floral vegetation in understory plant communities in a forested ecosystem only accounts for less than 1% of the total biomass of a forest, they contain most of the floral resources of a forest. The diversity of understory honey plants determines visitation rate of pollinators such as honey bee (Apis mellifera) as they provide rich food resources. Since the flower visitation and foraging activity of pollinators lead to the provision of pollination service, it also means the enhancement of plant-pollinator relationship. Therefore, an appropriate management scheme for understory vegetation is essential in order to conserve pollinator population that is decreasing due to habitat destruction and disease infection. This research examined the diversity of understory honey plant and studied how it is related to environmental variables such as (1) canopy density, (2) horizontal heterogeneity of canopy surface height, (3) slope gradient, and (4) distance from roads. Vegetation survey data of 39 plots of mixed forests in Chuncheon, Korea, were used, and possible management practices for understory vegetation were suggested. Results: This study found that 113 species among 141 species of honey plant of the forests were classified as understory vegetation. Also, the understory honey plant diversity is significantly positively correlated with distance from the nearest road and horizontal heterogeneity of canopy surface height and negatively correlated with canopy density. Conclusions: The diversity of understory honey plant vegetation is correlated to vegetation structure and human impact. In order to enhance the diversity of understory honey plant, management of density and height of canopy is necessary. This study suggests that improved diversity of canopy cover through thinning of overstory vegetation can increase the diversity of understory honey plant species.

한반도 주변 3개 해역은 서로 다른 지형과 다양한 해류의 교차로 종다양성의 근간이 된다. 또한, 복잡한 해류가 만나는 전선 주변으로는 좋은 어장이 형성된다. 그러나, 남획에 의한 자원의 감소 및 EEZ 발효에 의한 어장의 축소는 새로운 수산자원 관리법을 필요로 하게 되었다. 수산자원의 효율적 관리를 위해 우선 다양한 해양환경에 적응한 지역개체군의 실체를 파악하는 것이 필요하다. 지역개체군의 형태 및 유전에 관한 연구는 자원의 관리단위 및 구역을 명확히 하는 데 기여할 것이다. 최종적으로 해역별 수산자원의 관리방안 제시가 가능할 것으로 기대된다.

The aim of this research was to look into the relationship between leadership; transformational leadership, transactional leadership, and employee innovation, as well as the mediating impact of cultural diversity between leadership and employee innovation. Structured questionnaire was used to collect the data from 633 public and private universities' employees in the United Arab Emirates (UAE) with the help of the stratified sampling technique, and hypothesis verified through structural equations modelling (AMOS-21). Findings of the study shows that leadership has positive impact on employee innovation and cultural diversity partially mediates the relationship between leadership and innovative performance of UAE universities' employees. Practical implication of the study is to understand how universities can enhance their employees' innovation which is crucial for their competitiveness and survival. Moreover, the increasing prevalence of cultural diversity, as work arrangements in universities, raises the question of how to successfully manage employees. Although few studies have looked into how transformational and transactional leadership styles affect employees' innovation performance, this study expands on the topic by concentrating on sub-dimensions of leadership that foster innovation through idea generation and execution at the United Arab Emirates universities. This study offers valuable insights for educational leaders and throws light on the main characteristics of leadership which helps the employees to perform better in terms of innovation.

The aims of the study were to analyze (1) the effects of Prosopis juliflora (Prosopis) on the spatial distribution and soil seed banks (SSB) diversity and density, (2) the effects of environmental factors on SSB diversity and density (number of seeds in the soil per unit area), and (3) the effects of animal fecal droppings on SSB diversity, density, and dispersal. Aboveground vegetation data were collected from different Prosopis-infested habitats from quadrats (20 × 20 m) in Prosopis thickets, Prosopis + native species stand, non-invaded woodlands, and open grazing lands. In each Prosopis-infested habitats, soil samples were collected from the litter layer and three successive soil layer, i.e., 0-3 cm, 3-6 cm, and 6-9 cm. Seeds from soil samples and animal fecal matter were separated in the green house using the seedling emergence technique. Invasion of Prosopis had significant effects on the soil seed bank diversity. Results revealed that the mean value of the Shannon diversity of non-invaded woodlands was being higher by 19.2%, 18.5%, and 11.0% than Prosopis thickets; Prosopis + native species stand and open grazing lands, respectively. The seed diversity and richness, recovered from 6-9-cm-deep layer were the highest. On the other hand, the density of Prosopis seeds was the highest in the litter layer. About 156 of seeds/kg (92.9%) of seeds were germinated from cattle fecal matter. However, in a small proportion of seedlings, 12 of seeds/kg (7.1%) were germinated from shot fecal matter. Thus, as the seeds in the soil were low in the study areas, in situ and ex situ conservation of original plants and reseeding of persistent grass species such as Cynodon dactylon, Cenchrus ciliaris, Chrysopogon plumulosus, and Brachiaria ramosa are recommended.

This study was conducted to evaluate the ecological characteristics of forest cover types which were classified by cluster analysis in the natural forest of Sobaeksan on the basis of the vegetation data from the point-quarter sampling method. Recognized forest cover types were 1) Mixed mesophytic forest, 2) Taxus cuspidata forest, 3) Fraxinus rhynchophylla-Quercus mongolica forest, 4) Betula ermanii forest, 5) Pinus densiflora forest, 6) Quercus mongolica mixed forest, and 7) Quercus mongolica pure forest. For those of classified types, the species composition was expressed by importance value (IV) to describe the community floristically. The species diversity was quantified using the Shannon's diversity index. The results showed that the forest cover types were characteristically different from one another in growing species and compositional rates, depending upon the type which was formed by a number of similar vegetational sample points. Species diversity indices (H') of total and overstory both were the highest in the mixed mesophytic forest (3.530 and 2.880, respectively), and lowest in the Q. mongolica pure forest (2.122 and 0.000, respectively) with only one canopy species. The highest species diversity in the mixed mesophytic forest may due to the relatively high species richness and evenness in the forest cover types. The description on ecological characteristics were suggested to understand the formation and development of forest cover types in this study area.

The purpose of this study is to explore the effect of creativity management factors on perceived R&D performance. To do this, the data (885cases) were collected from 19 Korean Government-supported Research Institutes, and 3 hypotheses derived from the model of creativity management(after here CM) were tested. Major findings are as follows: 1) CM constructs are grouped into diversity, autonomy, connectivity, redundancy and flexibility factors; 2) The major factors that can explain R&D performance perceived by scientists and engineers are connectivity, autonomy, diversity and flexibility; 3) All CM factors have significant relationship with satisfaction of the employees; 4) Flexibility and connectivity factors give effects on turnover intention of the members. This study has some limitations in model building and empirical testing. This study, however, provides theoretical and managerial implications about CM and R&D management, particularly Government-supported Research Institutes in Korea.
