  • This study was conducted to eliminate Myocastor coypusMolina, 1782 (Nutria) from Jeju Special Self-Governing Province, South Korea. Habitat identification and eradication were carried out from September to November 2013, and a survey was carried out until June 2022 to check whether the eradication was successful. The habitat was identified with unmanned cameras, interviews, and literature surveys, and the capture was performed using the trapping method with food to attract nutria to the habitat area. The study area for the follow-up survey, which was set relatively wide considering nutria's home range, included wetlands and rivers within 4.0 km2 of the habitat area (eradication area). As a result, nutria's habitat was confirmed only at Songdang Ranch, Songdang-ri, of Jeju Island, with traces of habitat (footprints, excrement, and burrows) confirmed in waterways and ponds within the pasture. Eight individuals were captured, including four females, three males, and one individual in too advanced a state of decay to identify the sex. The follow-up survey thoroughly investigated the habitat and its surroundings, focusing on three areas with permanent water, Seongeup Reservoir, Cheonmi Creek, and Molsuni Pond, but no signs of habitat were identified. Therefore, it is determined that nutria inhabiting Jeju Island has been completely eradicated. It is believed that the successful eradication of nutria in the Jeju Special Autonomous Region was possible due to a synergy between 1) the eradication of nutria at the beginning of the settlement phase through rapid capture after confirming the nutria habitat and 2) the delayed expansion period because of rare presence of wetlands, where water is constantly stagnant, on Jeju Island. These results imply that quickly identifying the ecological characteristics of the species and preventing disturbances before they or at the beginning of the ecological disturbance through control and eradication at the initial stage of settlement before the expansion stage is an effective measure to cope with the influx of alien species.

  • This study evaluated the salt tolerance of Italian ryegrass varieties under various salt stress conditions. Seven varieties, including Kowineary, Greencall, Greenfarm, Greenfarm 3, IR 603, IR 605, and IR 901, were used in this experiment. Under various salt concentrations, there was no significant decrease compared to the control at salt concentrations of 0.1% to 0.3%. IR 901, Kowineary, and IR 605 had a lower relative reduction rate, but the absolute growth of IR 603 was the highest among the varieties. Among chlorophyll fluorescence parameters, ABS/RC, TRo/RC, ETo/RC, and DIo/RC values (activities expressed per reaction center) showed a significantly negative correlation with growth rates. In the experiment where the salt concentration was drastically increased, the growth decreases in Greenfarm 3 and IR 901 were relatively small compared to other varieties. Among the relative ratio of chlorophyll fluorescence parameters, ABS/RC, TRo/RC, ETo/RC (after 1 hour of salt concentration increase), and PIABS (3 hours, 7 days) showed a significant positive correlation, and DIo/RC (3 hours, 1 day) showed a negative correlation with plant growth. In the experiment where the salt concentration was drastically decreased, the growth increases in Greenfarm, IR 901, and Kowineary were relatively high compared to other varieties. Among the relative ratio of chlorophyll fluorescence parameters, ABS/RC, ETo/RC, DIo/RC (5 hours), and PIABS (1 hour) showed a significant positive correlation with plant growth. In summary, among the seven varieties, Kowineary and IR 901 had superior relative growth (compared to the control) under various salt stress conditions. IR 603 showed a greater decrease in relative growth but had the highest absolute growth amount under salt stress conditions. In addition, some parameters related to chlorophyll fluorescence showed a significant correlation with early growth, which could be used as indicators of the initial growth of IRG under salt stress.

  • The three means of listening, reflection and meditation (${\acute{s}}raava{\d{n}}a$, manana and $nididhy{\bar{a}}sana$) which are central devices of practice in $Ved{\bar{a}}nta$ philosophy should be understood not as a continuative step but as a methodological extension on condition of having one and the same purpose. In other words, the three means should be interpreted in a listening-oriented manner, in which the process has to be methodologically extended to reflection and meditation only when the direct knowledge on the reality is not gained in listening. This kind of interpretation can be more justified by displaying significant characteristics of Indian philosophy implied in the three means. It can be easily said that $Ved{\bar{a}}nta$ belonging to the liberation-centric tradition is a project of 'regaining essential self' through which the self becomes essential self by knowing that self. In this case the listening-oriented interpretation coincides with the basic teachings of $Ved{\bar{a}}nta$, since listening alone can be a sufficient means for obtaining knowledge of the original self. Further, as the project of 'regaining essential self' is carried out by the three means, these can be called a sort of 'event' that is carried out according to the scenario of $Ved{\bar{a}}ntic$ metaphysics. In this case listening is a course of comprehending the scenario of event participated by oneself, and that participant can accomplish the project by way of listening the scenario alone judged as somewhat more effective for liberation. However, in the later $Ved{\bar{a}}nta$ there arises a meditation-oriented interpretation of which three means are regarded not as a methodological extension but as a continuative step, because of the emphasis on meditation under the lasting influence of other philosophical systems. This is a result of epistemic desire that tries to convert what is heard to what is specially perceived or what is given to what is accepted. It may be said that this interpretation emphasizing the phased transition from the indirect to the direct of knowledge is an attempt to rationalize the repetitive delay of event as the actual failure of project. Furthermore, an assertion of the later $Ved{\bar{a}}nta$ which refers the fourth means called $sam{\bar{a}}dhi$ is based on the logic that the self-realization is possible apart from and outside the text, and accordingly it is incompatible with an assertion of the early $Ved{\bar{a}}nta$ that the self-realization is a reproduction as it is of the scenario guided by the absolute text. After all, the standard interpretation on the three means in $Ved{\bar{a}}nta$ have to be the listening-oriented, but not be the meditation-oriented or the $sam{\bar{a}}dhi$-oriented.

  • This paper aims to explore the citation patterns of conference papers in 'Information Science' discipline and to analze impacts of various cited works-related factors on future citations of conference papers. Existing bibliometric studies has investigated citation patterns and the statistical relations between a variety of bibliographic factors and the future citations of literature. However, the attentions have been focused largely on journal articles, and the bibliometric studies targeting conference papers are still in an infant stage. Therefore, this study, which is based on 1,904 conference papers in 'Information Science' field, examined several citation patterns and the contributions of the factors about cited works - the number of cited works, type of cited works, citation rates and ages of cited works at the time of being cited and the rate of self-citedness - to the future citation of the citing target articles. The data source of this study including the properties of target articles and cited works and citation rates of target articles was Scopus. As the results, 53% and 29% of the cited works were conference papers and journal articles, respectively. 14% of them are non-traditional types such as web pages, technical reports, patent, etc. More than 60% of the cited works were 5 years old or less. Among several factors considered in this paper, the number of conference papers and the number of non-traditional types of works are the most contributing factors on the citation rates of target articles. The recency of the cited works is also significant contributor on the citation rates of target articles. That is, the target articles citing more conference papers and non-traditonal types of works earned more citations. The target articles citing recent works also earned more citations.

  • The purpose of this thesis is to explore the fundamental reasons and general circumstances of the introduction of geometric shape to the 20th century's design education. The modern design education was directly influenced by the German Kindergarten Movement and its educational ideal, so they began to employ geometric shapes in visual education. When Friedrich Frobel, a professional German child educator of the 19th century, invented the 'Spielgaben,' it soon became a popular educational tool. It was a turning point in the child educational system, from then they began to actively employ 'tools' in art education. The Spielgaben was created based on the geometric principle of a popular block game of the 19th century. On the other hand, a game program called 'Bechaftigungsmaterial' led early Modernists to adopt geometric shape in their works. Then, geometric shape were applied to a primary educational program designed by the Bauhaus that gave birth to the Modern design education in the 20th century. likewise, the substantial reasons why the principles of point/line/plain and geometric shapes had been taken in the 20th century design education can be explained through this historical background. This research is to investigate how Kindergarten Movement and Modern design education can be associated with each other, particularly in the light of geometric elements. Therefore, I first referred to the historic records in order to reveal their relation, and then analyzed the similarities and differences between the two activities. In result, I could explore the relationship between child educational tools and the 20th century's design education.

  • The purpose of this study is to examine teachers' stages of concern and levels of use about SW education based on Concerns-Based Adoption Model and to provide implications for teacher education. For this purpose, 152 survey responses were collected from elementary school teachers in South Korea. The result indicated that elementary school teachers' concerns about SW education showed the nonuser pattern in that teachers score highest in stage 0(awareness) to stage 2(personal) and in stage 6(refocusing). Additionally, teachers who are currently implementing SW education showed a tendency to be in the level of mechanical use or routine, and more than half of the teachers who are not implementing SW education showed no motivation to change current practices. There were statistically significant differences in the stages of concern depending on gender, teaching experience, SW training experience, SW teaching experience, and there were differences in the levels of use depending on the teachers' grade level in charge, SW training experience, and SW teaching experience. Based on the results of the research, various SW related programs as well as successful SW education experience for teachers need to be provided for teacher education in order to promote SW education.

  • On 7 December 2007, the Hong Kong registered tanker Hebei Spirit, laden with 209,000 tonnes of crude oil, was struck by the crane barge Samsung No 1, whilst at anchor about five miles off Taean on the West Coast in Korea. About 10,500 tonnes of crude oil escaped into the sea from the Hebei Spirit. The recent oil leakage from a tanker in seas off Taean has turned the sea farms and fishing areas on the country's western coast into a sea of oil. Analysts say the spill is considered as one of the world's devastating sea pollution cases involving oil. In our contemporary society where people are exposed to potential dangers in every aspect, no one can be free from such dangers. With an increase in human casualties due to disaster, disaster reporting plays a vital role in preventing and minimizing damages. Despite such enormous significance, however, Korean disaster reporting has not performed effectively. In this contexts, this study analyzed the problems of disaster reporting in Korea, with the case of Hebei Spirit oil Spill in Taean-gun. And, this study suggest the establish ways and means needed to improve the disaster reporting in Korea with the case of Hebei Spirit case.

  • Culture is being created and consumed as several form by human development. Populace is forming through movement of mass of people to specific place which influenced by urbanization and industrialization. Since cultural products are created on base of economic principles cultural content makers are make culture products after lot of study and analyze. In early days popular culture was accepted only by the meaning of the text which has settled already via country or company which was holding the capital. But today we can apply culture products freely by the power of public opinion and media art's growth. Especially fandom is giving the opportunity to consume the image of cultural products actively and offering the good influence to make it by several ways of activities to the culture producers. In this study, consumption as a cultural group formed by the fandom in public will be transformed into participatory groups by the influence of cultural activities with fan art reproduction. These changes in the consumption of culture products will make it in positive way. Thereby culture creator who thinks fandom as a group of culture capital maker only use it now for the indicator for predicting success of culture products. Will find out in this study how culture consumption is accomplishing by fan fiction and fan illustration in the fandom culture and how reproduced fan art is affects to culture creators.

  • The webtoon market has been consisently developing in the digital market. Under such circumstances, The Korea webtoon market is rapidly growing and leading of them. This is the time to prepare the base of a stable environment for the webtoon market which shows a swift rise. The Korean webtoon is surely aiming at the global market as well as the domestic one. As the Korean webtoon companies spread out to the world briskly, The leading publication cartoon market, Japan tries to break into the Korean digital market. The domestic market that has the good-quality cartoons through exportation and importation to make people of all ages enjoy them. and also the Korean webtoon is in the center of the global webtoon markert. The early model of Korean webtoon, line-webtoon is translated in English, Chinese, Thai language and Indonesian language to use on the mobile applications and web. Nevertheless, It is just the stating point. With Eradicating of the Achilles heel of the digital contents, illegal distribution and finding materials for cultural discount rate minimized cartoon, The Korean webtoon can become the highest in the global market and hold it. Moreover, not only webtoon but also published cartoons are existing together to have a long run. Beyond the existing cartoon books printed on paper, we should reach toward the digital books with portability and economic feasibility to make the contents stay out longer.

  • The purpose of this study is to examine how the cultural aspects of the publication of literary collections have been changed from its time throughout the entire Joseon Dynasty. At the royal court in the early Joseon Dynasty, the need for publication of the literary collections has consistently arisen to preserve writings of the noted sages, and the Joseon government was also taking the lead and promoting the publication of the literary collections. From the 16th to the early 18th century, the publication was intensively made at the local governments led by local governors. From the 17th to the early to middle of the 18th century, the finances of local governments were limited with the changed taxation system, and there had been a dramatic decrease in the number of literary publication projects. On the other hand, with the sudden increase of the number of Seowons during the reign of King Sukjong, the focus of the literary publication was moved to Seowon from the 18th to the 19th century. After the enforcement of the Seowon Abolition Decree, the collections were still published at Seowons, however from the end of 19th century, the publication of literary collections had been explosively made by aristocrats who did not belong to the institution of Seowon or could not receive Seowon's support, which spreaded over the entire Yangban culture.
