In this study, I examined the visual elements for narrative structure and the symbols, scene components and visual styles in the images through analyze the flat staging in Tomm Moore's animated feature film, . As a research method, I figure out the general theories about staging and analyze extracted scenes which revealed flat staging in the , then summarize and clarify the flat staging production elements and features of Tomm Moore. As a result, in , the composition of the screen using the basic shapes, the screen composition containing the spiral which is symbol of the Celtic traditional pattern, the stable and flat frame expression through the balanced screen composition, expression of spatial sensation using perspective, appearance of the period by using the inverted perspective, and composition that can emphasize the flat formability are appeared as a characteristic. Through this, the two-dimensional planarity was maximized to convey the feeling of appreciating the illustrations of fairy tales. Tomm Moore, who produced animation based on folk tales in order to inherit the traditional culture of Ireland, has been attracting worldwide attention because of its flat staging to help narrative, enhancing the original expression and performance of animation. I hope that this study will be used as basic data for industry workers and researchers who make unique and excellent animated feature film.

홍합, 따개비 등의 접착성 해양생물은 선박의 하부나 발전소 해수 공급용 튜브에 부착하여 운영 효율을 저하 시키고, 냉각기기 고장을 유발하는 파울링(Fouling) 문제를 야기시킨다. 일반적으로 이러한 문제에 대응하기 위해서 초접착성 해양생물이 주로 부착하는 부위에 $Cu_2O$, ZnO 등을 포함한 유기화합물로 표면처리를 하여 부착방지를 하고 있지만, 이 소재들을 장시간 사용 시 해양 오염 및 부식을 가속화하는 문제를 초례하기 때문에 최근에는 사용을 금지하고 있다. 이러한 유해성 소재 문제를 해결하고자 친환경적이고 부작용이 없는 초접착성 해양생물 부착방지 소재를 개발하고자 하였다. 본 연구에서는 낮은 표면장력을 갖는 PDMS(Polydimethylsiloxane) 소재를 기반으로 소수성 oil을 침투시킨 I-PDMS(Oil-Polydimethylsiloxane) 표면처리법을 고안하였고, 이 방법을 활용하여 초접착성 해양생물에 대한 부착방지 성능을 향상시키고자 하였다. 기존의 개발품들 보다 성능이 향상된 I-PDMS 제조하고자, Nano-indentation을 이용한 기계적 특성 평가, X컷 및 cross-cut을 이용한 부착력 평가, 실제 바다환경에서 해양생물의 부착력 시험, 바다 환경을 모사한 수조에서의 I-PDMS와 비교군 기판에서의 홍합 거동, 홍합과 기판의 접착강도 시험, 해양 미생물 평가를 실시하였으며, 이를 통해서 I-PDMS 성능 및 내구성을 입증하고자 하였다.

The Ocean is a rich source of diverse living organisms include viruses. In this study, we examined the microbial communities in the sea adjacent to Jeju Island in two seasons by metatranscriptomics. We collected and extracted total RNA, and, using the next-generation sequencing HiSeq 2000 and de novo transcriptome assembly, we identified 652,984 and 163,759 transcripts from the March and December samples, respectively. The most abundant organisms in March were bacteria, while eukaryotes were dominant in the December sample. The bacterial communities differed between the two samples, suggesting seasonal change. To identify the viruses, we searched the transcripts against a viral reference database using MegaBLAST with the most identified being bacteriophages infecting the marine bacteria. However, we also revealed an abundance of transcripts associated with diverse herpesviruses in the two transcriptomes, indicating the presence or possible threat of infection of fish in the sea around Jeju Island. This data is valuable for the study of marine microbial communities and for identifying possible viral pathogens.

The problem of the cases of Soribada and Winny is their duplexity that they could be used legally and illegally. The issue called 'The crime of aiding through the neutral behavior' is about whether the program developer who shared the file sharing program letting unspecified public infringe the copyright could be punished or not. Many theories about limiting the traditional scope of punishment of aider have been maintained. However, it is questionable whether it is possible to limit the scope of punishment following the former cases and theories even for the action that is causal and facilitates the principal's criminal conduct, like the aid through the neutral action which is hard to perceive as illegal aid because of its characteristics. Therefore, using the case of Soribada in Korea and the case of Winny in Japan as the examples of illegal aid through neutral behavior case, this paper examines the characteristics and problems of aid through existing theories and cases, and suggests new scope of punishment limitation standard through the elaboration of the action of aid and judgment of degree.

Surface and bottom sea water samples were harvested from the 5 stations in the marine ranching ground of Tongyeong coastal water from year 2000 to 2002. Cell number of heterotrophic bacteria was determined by using the plate counting method to explore the variation of the cell population of heterotrophic bacteria. Sea water samples collected in summer (in July and August) contained much larger number of heterotrophic bacteria than those harvested in spring, autumn and winter. Heterotrophic bacteria were usually more abundant in surface sea than in bottom sea water. However the reverse was true for sea water collected in December 2001 and February 2002 due to suspended solids accumulating more abundantly in seabed area because of the slower convective current of the sea water in winter. Number of heterotrophic bacteria did not have a strong relationship with frequency of typhoon indicating that the path and powerfulness of the typhoon, localized torrential downpour and temperature variation accompanying the typhoon should be considered all together at the same time as well as the frequency of typhoon to explain clearly the variation of cell number of heterotrophic bacteria. The dominant species isolated from the marine ranching ground of Tongyeong were identified to be Pseudomonas fluorescens, Pseudomonas stutzeri, Acinetobacter lwoffii and Sphingomonas paucimobilis.
