  • This study emphasizes that the survival strategy of universities should be a co-evolution strategy based on ecological thinking. Therefore, the purpose of the research is to present a theoretical framework for dividing the university innovation ecosystem into four stages and building a co-evolution strategy for each step, as universities play a prominent role in regional innovation ecosystems. Thus, our research method focused on literature research, and the theoretical framework for the university innovation ecosystem used Moore's Enterprise Ecosystem Model (1996). The university's ecological innovation strategy is divided into four stages of development, and a step-by-step co-evolution strategy is presented. Findings are summarized as follows. The pioneering stage involves the creation of values of the university-led innovation ecosystem. The expansion stage focuses on the establishment of critical mass. The authority stage covers maintaining authority and bargaining power. The renewal stage features continuous performance improvement. In particular, this theoretical model of the university-regional innovation ecosystem is meaningful in that it provides a theoretical basis for enhancing the effectiveness of government financial support projects, and for individual universities, it provides a framework for strategies suitable for their ecosystem building process.

  • Natural Medicine is a medical system that tries to find the cause and cure of the disease in the nature emphasizing on natural healing power of human body. The most important value of traditional medicine in east Asia lies on the fact that this medicine is a medical culture and natural medicine that was selected by instinct and human nature reflecting the best possible remedy by the wisdom of evolution, and views the living phenomenon based on relation and circulation. This medicine is a natural medicine that tries to recover and promote the natural healing power by vitality and is a system that cumulates various empirical information about unique and complicated life phenomenon as a legacy of evolution in the body and the disease. The understanding of variation and adaptation of human species should be based on thorough knowledge of origin, instinct and nature of human as well as knowledge of survival and adaptation of human and environment based on evolution. And through this insight, the prevention and treatment of modern diseases should be developed. In this regards, traditional medicine in east Asia should be highlighted again as a study on adaptation and harmony of penetrating the cultural history of mind which has led the history of biological body and change of society and culture, and the repository of practical wisdom and knowledge.

  • Background: Longitudinal connectivity in river systems strongly affects biological components related to ecosystem functioning, thereby playing an important role in shaping local biodiversity and ecosystem health. Environmental DNA (eDNA)-based metabarcoding has an advantage of enabling to sensitively diagnose the presence/absence of species, becoming an efficient/effective approach for studying the community structure of ecosystems. However, little attention has been paid to eDNA-based biomonitoring for river systems, particularly for assessing the river longitudinal connectivity. In this study, by using eDNA we analyzed and compared species diversity and composition among artificial barriers to assess the longitudinal connectivity of the fish community along down-, mid- and upstream in the Hotancheon from the Geum River basin. Moreover, we investigated temporal variation in eDNA fish community structure and species diversity according to season. Results: The results of species detected between eDNA and conventional surveys revealed higher sensitivity for eDNA and 61% of species (23/38) detected in both methods. The results showed that eDNA-based fish community structure differs from down-, mid- and upstream, and species diversity decreased from down to upstream regardless of season. We found that there was generally higher species diversity at the study sites in spring (a total number of species across the sites [n] = 29) than in autumn (n = 27). Nonmetric multidimensional scaling and heatmap analyses further suggest that there was a tendency for community clusters to form in the down-, mid- and upstream, and seasonal variation in the community structure also existed for the sites. Dominant species in the Hotancheon was Rhynchocypris oxycephalus (26.07%) regardless of season, and subdominant species was Nipponocypris koreanus (16.50%) in spring and Odontobutis platycephala (15.73%) in autumn. Artificial barriers appeared to negatively affect the connectivity of some fish species of high mobility. Conclusions: This study attempts to establish a biological monitoring system by highlighting the versatility and power of eDNA metabarcoding in monitoring native fish community and further evaluating the longitudinal connectivity of river ecosystems. The results of this study suggest that eDNA can be applied to identify fish community structure and species diversity in river systems, although some shortcomings remain still need to be resolved.

  • Marketing practice varies among firms. However, the prescriptive literature emphasises a universal view of practice, a 'one size fits all' view. This paper addresses the issue of explaining diversity in marketing practice in competitive space and in time. Diversity in competitive space reflects the existence of different routes to high performance. Diversity in time reflects some combination of change in the individual firm and change in a population of firms. In the former case, diversity is shaped by organisational change; in the latter by the disbandment and founding of firms in the population. In so far as diversity is the norm, the manner in which practice will be shaped by evolutionary processes is considered. Fnally, the role of the academy as one of the forces driving the evolutionary process is discussed. Miles and Snow's (1978, 1986) work is taken as a main point of departure in the search for explanation and ecological and evolutionary concepts are drawn on for support and to suggest an explanation for the nature of diversity over time.

  • The genus Philanthus Fabricius, 1790 in Korea are reviewed, and two species, Philanthus triangulum and P. coronata, are treated. The former is new to Korea. This species is easily separated from congeners by dense punctures in propodral enclosure and tri-forked marking in lower face. DNA barcoding test is supportive in our identification as well as conspecitficity of Korean materials showing variation in size and coloration. The observed data on flower associations of this species specified with domestic localites and date are separately provided. The current status of Philanthus coronatus that has been the only representative of the genus but forgotten for a lengthy time in Korea is discussed.

  • Pagurus is the most diverse hermit crab genus in Korea. In this study, the cytochrome c oxidase subunit I (COI) and 16S rRNA of 24 individuals from four Korean Pagurus species (i.e., 7 Pagurus brachiomastus, 8 P. proximus, 8 P. simulans, and 1 P. rectidactylus) were sequenced and analyzed. No genetic difference was found between the COI and 16S rRNA sequences of P. brachiomastus and P. simulans, and the COI sequences of P. rectidactylus and P. quinquelineatus (comparative species from NCBI). Considering the morphological and ecological characteristics together, we assume that P. simulans and P. rectidactylus are subspecies of P. brachiomastus and P. quinquelineatus, respectively. This study should facilitate further research on the taxonomic status of these species.
