  • Modern culture has describing the year's situation along the social environment. A literary work changed as if the year's situation change. Therefore we can understand the age through the literary work and get knowledge the social request of the year's. This literary works have made a chance to know approaching more closely to user as producing media resources. Recently, IT convergence and digital convergence become a new trend to combine each other academic area and get much synergy effect. In this paper, we propose an application and design of the ontology that needs to make digital content from modern literary work's information. For this works, we specify the structure of the year's literary work and the relation of each factor. The specification method used topic map. Each relation model was specified the connection by topic vector.

  • Background: Halophyte plant (HPs), a salt-resistant flora, has been reported to provide several health benefits, but the knowledge of its cosmeceutical potential is still ambiguous. Here, 70% ethanol extracts of 22 HPs collected from along the coast of South Korea were investigated for their potentials of antioxidant, anti-aging, and whitening properties for use as materials in novel cosmeceuticals. Methods: Antioxidant activities were determined by DPPH (1,1-diphenyl-2-pricrylhydrazyl) free radical and hydrogen peroxide scavenging assays, and skin aging-related enzyme activities (anti-elastase, anti-collagenase, anti-hyaluronidase, and anti-tyrosinase) were evaluated by using the spectrophotometric method. Results: Among the 22 HPs, we found that Ischaemum antephoroides f. coreana and Atriplex gmelinii extracts presented the strongest scavenging effects against DPPH free radical and hydrogen peroxide, respectively. Our finding additionally suggested that Salicornia europaea extract might provide a major source of anti-elastase and anti-hyaluronidase; meanwhile, Rosa rugosa extract showed the highest anti-collagenase effect. Furthermore, the highest tyrosinase inhibitory activity was possessed by Spartina anglica extract. Conclusion: These findings may suggest that halophyte plants showing biological activities may be potent inhibitors of tyrosinase, elastase, collagenase, and hyaluronidase and could be useful for application in cosmeceuticals.

  • Basic science teaching and clinical education should be integrated whenever appropriate, and the development of skills, values, and attitudes which are emphasized to the same extent as the acquisition of knowledge in nursing. Problem-based learning provides a students-centered learning environment and encourages an inquisitive style of learning. The purpose of this paper is to review and comment the role of tutors and students on problem-based learning. The use of problem-based learning places a high demand on faculty members' time and support. The role of tutors in Problem-based learning focuses primarily on issues of developing and teaching the curriculum and on organizational implementation and institutionalization. Tutors are an integral part of course planning. Tutors serve as a constant source of feedback on student needs and concerns to the course director and constitute an informal steering committee while the course is in progress. Tutors write cases, develop student evaluation methods, recommend resources, suggest modifications in lectures and laboratories. Students have a limited amount of time available to study what is traditionally defined as the core content of nursing. But, the role of students in Problem-based learning would be active, independent learners and problem-solvers rather than passive recipients of information. Students using a deep level approach attempt to integrate what they learn with what they already know, to understand the meaning underlying the material to be learned, and to look for explanations rather than facts. Students are encouraged, with appropriate guidance, to define their own learning goals, to select appropriate experiences to achieve these goals, and to be responsible for assessing their own learning progress. Problem-based learning is more flexible and meaningful, by encouraging student interaction, and by having a better emotional climate than the conventional learning.

  • Strategic alliances developed as formalized inter-organizational relationships are core vehicles to share information, resources and knowledge. The structural characteristics of strategic network constructed by strategic alliances have been important agenda in strategic management discipline. This paper has two folds in analysing the strategic network formulated by project level alliances in Korean construction industry. First, we investigate the strategic network using the tools and methods of social network analysis, such as centrality, cohesion, structural equivalence, and power law. Second, the performance of firms within networks are analysed longitudinally with panel data analysis. We have found that the strategic networks in this industry has scale-free characteristics, where the degree distribution fits the power law, and the vertically equivalent structure is clear. We also present that the performance of firms are continuously affected by the degree centrality of firms in this network for the last 10 years.

  • In the contemporary modern society, information and knowledge generate a set of new social values. These changes demand a transformation not only in socio-cultural and educational spheres, but also, specifically, in the field of culture and art education. Culture and Art education emphasizes the integration and cross-discipline of other related fields which have great impact on culture and arts. This study applies theoretical analysis of Animation education in the context of culture and art education. Animation education takes an interdisciplinary approach to integrate various subjects in the field of culture and art education. Animation, as a form of culture and art education, plays an educational role in the social classroom. Animation education should be developed and expanded to become a regular classroom course. The goal of Animation education is to pursue and develop a connection with other educational courses of study. In order to strengthen the role of Animation education, we should first re-structure the pedagogical role of Animation education. Secondly, Animation education needs to become a diversified and popularized education. Third, the cultivation of creative human resources is considered of vital importance to Animation education. Finally, the expansion of infrastructure and the establishment of a comprehensive support system for Animation education has to be established.

  • The university museum is working to discover, research, and exhibit cultural artifacts as well as use them as resources of education and academic researches as one of the important organizations of the university. Current, however, university museums have the low-level usability caused by the reduction of financial and administrative supports of the university. One approach to solve this problem may be the design of mobile docent app for improving the accessibility of the museum. The app enables users get artifacts and education programs without the restriction and learn artifact-related knowledge easily. In this paper, we design and implement a new mobile docent app according to the analysis of content of the Chosun university museum as a real case study. In addition, we evaluate the functionality and usability of the proposed app by affordance-based questionnaire.

  • This paper is to inquire into nature of the educated's geography from 1905 to 1910 by researching relevant geographical resources in HAKBO published by the Academic Society. At that time, the Patriotic Enlightenment Movement was active, and the Academic Society attempted to enlighten people, to enrich the country, and to restore the sovereign right. The educated tried to understand the reality in view of social Darwinism and make their country the winner as well as the fit in the struggle for existence by this movement. Their effort can be seen in HAKBO and geography in it. The contents of geography in HAKBO was related to world-wide geographical information and intended to instil patriotism into the hearts of people. As their research methods, they adopted systematic geographical method by comparing between region and region, or studying relationships of the nature and human, and Hettner's regional geographical method which describes human after the nature. Hence, it is proved that the educated's geography in HAKBO introduced modem geography in western society for Patriotic Enlightenment and it used its geographical methods.

  • For the efficient discovery of knowledge and information from the observed systems, data mining techniques can be an useful tool for the prediction of water quality at intake station in rivers. Deterioration of water quality can be caused at intake station in dry season due to insufficient flow. This demands additional outflow from dam since some extent of deterioration can be attenuated by dam reservoir operation to control outflow considering predicted water quality. A seasonal occurrence of high ammonia nitrogen ($NH_3$-N) concentrations has hampered chemical treatment processes of a water plant in Geum river. Monthly flow allocation from upstream dam is important for downstream $NH_3$-N control. In this study, prediction models of water quality based on multiple regression (MR), artificial neural network and data mining methods were developed to understand water quality variation and to support dam operations through providing predicted $NH_3$-N concentrations at intake station. The models were calibrated with eight years of monthly data and verified with another two years of independent data. In those models, the $NH_3$-N concentration for next time step is dependent on dam outflow, river water quality such as alkalinity, temperature, and $NH_3$-N of previous time step. The model performances are compared and evaluated by error analysis and statistical characteristics like correlation and determination coefficients between the observed and the predicted water quality. It is expected that these data mining techniques can present more efficient data-driven tools in modelling stage and it is found that those models can be applied well to predict water quality in stream river systems.
