  • The roles and functions of domestic public libraries are diversifying, but various problems have emerged due to internally biased book lending. In addition, due to the 4th Industrial Revolution, public libraries have introduced a book recommendation system focusing on popular books, but the variety of books that users can access is limited. Therefore, in this study, the public library unborrowed book recommendation system was implemented limiting its spatial scope to Duryu Library in Daegu City to enhance the satisfaction of public library users, by using the loan records data (213,093 cases), user information (35,561 people), etc. and utilizing methods like cluster analysis, topic modeling, content-based filtering recommendation algorithm, and conducted a survey on actual users' satisfaction to present the possibility and implications of the unborrowed book recommendation system. As a result of the analysis, the majority of users responded with high satisfaction, and was able to find the satisfaction was relatively high in the class classified by specific gender, age, occupation, and usual reading. Through the results of this study, it is expected that some problems such as biased book lending and reduced operational efficiency of public libraries can be improved, and limitations of the study was also presented.

  • This study was carried out in August and September 2016 to investigate the species composition and biomass of benthic diatoms in Yubu Island, Gomso Bay, Imja Island, and Yeoja Bay tidal flat of Southwestern coast. There were 181 species of 48 genera in Yubu Island tidal flats, 194 species of 51 genera in Gomso Bay tidal flats, 224 species of 64 genera in Imja Island tidal flats and 188 species of 56 genera in Yeoja Bay tidal flats. A total of 274 species of 70 genera appeared. Pennales appeared more widely than Centrales and were dominated by Paralia sulcata and Navicula spp. Biomass of Yubu Island tidal flat ranged from $18.8-136.1mg\;m^{-2}$, $31.9-215.7mg\;m^{-2}$ in Gomso Bay, $2.9-120.2mg\;m^{-2}$ in Imja Island and $10.1-147.7mg\;m^{-2}$ in Yeoja Bay. The range of total biomass from 4 areas was $2.9-215.7mg\;m^{-2}$. The concentration of phaeopigment and degradation product of chlorophyll-a was $1.7-470.8mg\;m^{-2}$ in Yubu Island tidal flat, $52.3-277.2mg\;m^{-2}$ in Gomso Bay, $0.6-78.9mg\;m^{-2}$ in Imja Island and $39.1-346.3mg\;m^{-2}$ in Yeoja Bay. Compared with the results reported in this study area and the domestic tidal flats, it cannot be directly compared and evaluated due to various factors such as the timing of the survey, the frequency of the survey, the analysis method and geography. The southwestern coast of Korea has a variety of benthic diatoms and the high concentration of chlorophyll-a is the main determinant of primary productivity.

  • This study suggests a conceptual strategy and methodology for the risk assessment of the domestic abandoned mine fillers with fly ash. The fillers are composed of coal fly ash and solidification materials, and contain little toxic substances such as carbonates but also some heavy metals; therefore, those requires a risk assessment. The risk assessment should primarily focus on estimation of the effects to human health both on carcinogen and non-carcinogen aspects. The significant data such as toxicity and partition coefficients can be obtained from the national soil or mine environmental risk assessment guidelines. Accurate risk assessment of heavy metal contamination in the fillers may consume lots of time and efforts through site survey and instrumental analyses, etc. Moreover, it is inefficient to explore all of the factors as concentrations and categories in every heavy metal in the fillers, due to a high variety and complexity. Therefore, implementation of a preliminary risk assessment is suggested by using the literature data and the basic characteristics of the filler samples prior to the detailed risk assessment. Certainly, this presumes a thorough understanding of reliable sample analysis methods, exposure pathways, and relevant physicochemical and biological mechanisms.

  • Through the comparative analysisand inductive research on main creation styles of Chinese, American and Japanese animation films, a conclusion can be given out, which means that the animation film style of each country can hardly be formed without their own traditional painting art, aesthetics habits and ways of thinking. It is these characteristics that form their unique animation film style. America emphasizes realism art, development and utilization of new technology, Japan pays sepcial attention totraditional painting art and comic stories. In business aspect, they bring about different business models relying on the experience of satisfying the diverse needs of domestic and global entertainment markets. When it comes to the content field, they carry forward universal values and meet the individualistic heroismso that a variety of business animation films and art animation films find their ways into the global market and acquire great popularity among audiences from all over the world. Through the comparasion of American and Japanese animation films, a new view to analyze the animation films of China is created. Animation creation is largely based on the need of socialist ideology from 50s to 80s. Even though the purposes of animation film creations returned to satisfying the diverse requirements of commercial markets and audiences, the consequences, such as the break gap of creations and talents, the lack of diverse creative styles and commercial market operation mechanism, sitll affect China's animation films today. Japan found thier position from the American model and became successful. Nowadays, China need find our own creative style and position from American model and Japanese model. And the systematic reformings that are detailed in the government managements, industry standards, internationalized talents cultivation and accumulation are the essential point.

  • Recently, as the internet is widespread rapidly among the public, people can use a variety of useful information services through the internet. Accordingly, the protection of information supplied by computer networks 5 has become a matter of primary concern on the whole world. To accede to the realistic demands, it has been worked out some countermeasures to cultivate the experts in information security by the government and many educational facilities. Already the government authority has carried out the each kinds of concerning projects under the framed a policy, Five-Year Development Plan for Information Security Technology. Also, many domestic universities perceives such an international trend, and so they frame their plans to train for the experts in this field, including to found a department with respect to the information security. They are ready to execute their tangible works, such as establishment of educational goal, development of teaching materials, planning curriculum, construction of laboratories and ensuring instructors. Moreover, such universities lead to their students who want to be information security experts to get the fundamental knowledge to lay the foundation for acquiring the information security technology in their bachelor course. In this note, we survey and analyze the curricula of newly-established or member-extended departments with respect to information security fields of some leading universities in the inside and outside of the country, and in conclusion, we propose the effective model of curriculum and educational goal to train the students for the information security experts.

  • Because of the global warming, the Arctic Ocean is expected to be ice-free by the year 2035. When the Arctic Ocean will be opened, a number of national interests will become more salient as experiencing a shortened sailing distance and decreasing navigation expense, possibility of natural resources transport by sea from Arctic Circle, and indirect-profit making by building a herb port in Asia. To secure the national interests and support the free activities of people in this region, R.O.K government is trying to make advanced policies. In order to carry out the naval tasks in the Arctic Ocean, using the operational characteristics(mobility, flexibility, sustainability, presence of capabilities, projection) is necessary. To this end, ROK Navy should analyze the operational environment (O.E.) by its capability(weakness and strength), opportunity, and threat. R.O.K. Navy should make an effort over the following issues to implement the tasks in the Arctic Ocean: first, Navy needs to map out her own plan (Roadmap) under the direction of government policies and makes crews participate in the education·training programs in home and abroad for future polar experts. Third, to develop the forces and materials for the tasks in cold, far operations area, Navy should use domestic well-experienced shipbuilding skills and techniques of the fourth industrial revolution. Next, improving the combined operations capabilities and military trust with other countries in the Arctic region to cover the large area with lack of forces' number and to resolve the ports of call issues. Lastly, preparation in advance to execute a variety of missions against military and non-traditional threats such as epidemics, HA/DR, SOLAS, in the future operation area is required.

  • In South Korea, there is a growing domestic need for a biotope map which contains ecological and environmental geographic information of a city. After the production of a Urban Ecological Maps(biotope map) by the Seoul metropolitan government in 2000, Natural Environment Conservation Act was revised in 2017 to make it mandatory for a local government to draw up its own urban ecological map. The aim of the present study was to find out ways to utilize an urban ecological map as a mean of communication between natural environment planning and urban planning sectors in a preliminary stage before introducing a big framework of 'environmental and ecological planning.' The northern area of Incheon metropolitan city was selected as the target area for this study. The major research content includes a comparative analysis of special-purpose zones, urban planning zones, restricted development zones, and conservation forests with focus on biotope types and Grades 1 of 'Biotope Type Assessment.' Farmland biotopes and forest biotopes within an area designated as an urban zone (residential, commercial and industrial zones) need to be redesignated as a zone which can conserve them. Especially considering a high possibility of damage to a large scale of natural green areas, these areas need to be readjusted immediately. If the entire area designated as an urban planning zone is to be developed, it is likely to cause serious damage to natural biotopes in the area (56.2%), including farmland biotope (30.4%), forest biotope (15.0%) and grassland biotope (10.8%), and thus, readjustment is needed. In case of a conservation forest, as it can possibly be damaged by the designation of special-purpose zones, it is necessary to match the designation of conservation forests or a special-purpose zones with their biotope types. In conclusion, we present a variety of thematic maps for utilization of an urban ecological map and propose a phase-specific environmental and ecological plan. Phase 1 is the establishment of a urban plan in consideration of ecological status; Phase 2 is the independent establishment of an environmental and ecological plan by an environment department; Phase 3 is an integrated management of ecological planning system and urban planning system.
