In this paper, we are proposing a hierarchical segmentation method that first segments the video data into units of shots by detecting cut and dissolve, and then decides types of camera operations or object movements in each shot. In our previous work[1], each picture group is divided into one of the three detailed categories, Shot(in case of scene change), Move(in case of camera operation or object movement) and Static(in case of almost no change between images), by analysing DC(Direct Current) component of I(Intra) frame. In this process, we have designed two-stage hierarchical neural network with inputs of various multiple features combined. Then, the system detects the accurate shot position, types of camera operations or object movements by searching P(Predicted), B(Bi-directional) frames of the current picture group selectively and hierarchically. Also, the statistical distributions of macro block types in P or B frames are used for the accurate detection of cut position, and another neural network with inputs of macro block types and motion vectors method can reduce the processing time by using only DC coefficients of I frames without decoding and by searching P, B frames selectively and hierarchically. The proposed method classified the picture groups in the accuracy of 93.9-100.0% and the cuts in the accuracy of 96.1-100.0% with three different together is used to detect dissolve, types of camera operations and object movements. The proposed types of video data. Also, it classified the types of camera movements or object movements in the accuracy of 90.13% and 89.28% with two different types of video data.

Interviews are so important and meaningful that it is the heart of the documentary. In narrative film, it is focused as the story discourse, whereas documentary is strong in disclosure, which consists of narration and interview. In a TV documentary, interviews use conventional shots repeatedly, whereas in a documentary film that targets a relatively large screen, the interviewer's Mise-en-scene should consider the aesthetic depth. , which released in 2017 and used the audience for the third time in documentary film history, tries to make 40% of the volume of the main volume equal to the same angle. In a TV documentary, it is not uncommon for an interview cut to exceed 30 seconds, and if it exceeds 1 minute, immersion is significantly lowered, so the a mount and compression of the interview disclosure is important for both the director and the audience. In the case of the interview sequence of , it was the key to communicate the sub-plot with a relatively focused with long discourse, which is at least 8 minutes and 30 seconds to a maximum of 11 minutes, in a way that allows the audience to communicate. Furthermore, it was produced after the death of the protagonist Roh Moo Hyun, with the limitation that the voice of the protagonist was excluded, and the voice of Roh Moo Hyun was indirectly reproduced through the surrounding characters. In this study, it covers the meaning and scope of interviews in the production of documentary, and the aesthetic applications of the Mise-en-scene.

Numerous methods can be employed to teach students and farmers on soil science and fertilizer. The cartoon is one of the most effective teaching aids both for instructors and students. Instructor becomes a director of the cartoon to organize the framework of story based on the chapter of lecture. Director should adapt the regular sentence on soil science into the short and concise scenario suitable for the visual expression of the cartoon, followed by the selection of the scene for drawing. Next is to cast the instructor for the role of actor or sometimes supporter. After casting, the director starts to draw each cut of the cartoon in sequence. I published the cartoons in weekly serials in the farmer's newspaper for three years. Each cartoon was composed of eighteen cuts and formatted with the introductory, main and conclusive issues. Cartoon started with dialogues between the cast on subject to stimulate the interest by farmers, inserted the tables and graphs for the scientific knowledge and summarized the chapter. Major contents covered in the cartoons were glossary, nutrient uptake, pH, salt accumulation, moisture, pollution, chemical fertilizer, compost and other general aspects of soils. Cartoons had been very popular serial of the newspaper and are archived in the web for reviewing.

Laparoscopic surgery is a surgical procedure which uses long laparoscopic instruments through tiny holes in abdomen while watching images from a laparoscopic camera through umbilicus. Laparoscopic surgeries have many advantages rather than open surgeries, however it is hard to learn the surgical skills for laparoscopic surgery. Recently, some virtual simulation systems for laparoscopic surgery are developed to train novice surgeons or resident surgeons. In this study, we introduce the techniques that we developed for laparoscopic surgical training simulator for cholecystectomy (gallbladder removal), which is one of the most frequently performed by laparoscopic surgery. The techniques for cholecystectomy simulation include modeling of human organs (liver, gallbladder, bile ducts, etc.), real-time deformable body calculation, realistic 3D visualization of surgical scene, high-fidelity haptic rendering and haptic device technology, and so on. We propose each simulation technique for the laparoscopic cholecystectomy procedures such as identifying cystic duct and cystic artery to clamp and cut, dissecting connective tissues between the gallbladder and liver. In this paper, we describe the techniques and discuss about the results of the proposed cholecystectomy simulation for laparoscopic surgical training.

The 3-D analysis of terrain for route design and selection is being used as important basic data for effective judgement of political draft. This study is to decide efficient alignment of the entry route and design bridge by modeling, analyzing and displaying surface with digital terrain data. In this study we analyze slope, aspect, shaded-relief, line of sight and watershed on the base of DTM such as contour, TIN and grid. And we can not only esti mate end-area volume for road construction by calculating cut and fill and displaying mass-curve but also recognize the scene after execution with simulation of road and terrain. The result of this study reveals that visual effects of the 3-D terrain data are very effective for designer and decisionmaker to select and review alternative route with regard to terrain characteristics.

In this paper, we present a histogram and moment-based vidoe scencd change detection technique using hierarchical Hidden Markov Models(HMMs). The proposed method extracts histograms from a low-frequency subband and moments of edge components from high-frequency subbands of wavelet transformed images. Then each HMM is trained by using histogram difference and directional moment difference, respectively, extracted from manually labeled video. The video segmentation process consists of two steps. A histogram-based HMM is first used to segment the input video sequence into three categories: shot, cut, gradual scene changes. In the second stage, a moment-based HMM is used to further segment the gradual changes into a fade and a dissolve. The experimental results show that the proposed technique is more effective in partitioning video frames than the previous threshold-based methods.

This study analyzed the punk style shown in the movie Sid and Nancy (1986), based on a true story. The purpose of this study was to prove that the styles of the main characters had some discriminatory mode as an anti-fashion with not only the value system of the subculture but also the diverse cultural codes applied, revealing their identity. The scope of this study covered the 1970s when Sid died while a member of the Sex Pistols, but was limited to the analysis of Sid and Nancy's costumes. As theoretical background, this study reviewed the preceding studies, specialty books, movie-related sites and their postings, and on-line news reports. To analyze the movie costumes, relevant scenes on the DVD were captured, and thereby, the scenes were categorized per character and style but a performance scene was categorized Sid and Nancy as same punky wedding style because of intention spirituality to marriage by director, and thereupon, 17-cut images were used for the analysis of main characters' styles. Sid's style consisted primarily of black leather jackets, symbolic T-shirts, and jeans, whereas Nancy's style implied a punk style with added fetish styles. Even in the same punk style, their identities were symbolized through bricolage. Through this, subculture styles, were able to confirm that in addition to the value system of subculture, discriminatory modes as anti-fashion with various cultural codes played a role in revealing their identity.

In South Korea, most patients who visit trauma centers with abdominal injuries have blunt trauma, and penetrating injuries are relatively rare. In extremely rare cases, some patients are admitted with a long object penetrating their abdomen, and these injuries are referred to as abdominal impalement injuries. Most cases of impalement injuries lead to fatal bleeding, and patients often die at the scene of the accident. However, patients who survive until reaching the hospital can have a good prognosis with optimal treatment. A 68-year-old female patient was admitted to the trauma center with a 4-cm-thick tree branch impaling her abdomen. The patient was transported by a medical helicopter and had stable vital signs at admission. The branch sticking out of the abdomen was quite long; thus, we carefully cut the branch with an electric saw to perform computed tomography (CT). CT revealed no signs of major blood vessel injury, but intestinal perforation was observed. During laparotomy, the tree branch was removed after confirming that there were no vascular injuries, and enterostomy was performed because of extensive intestinal injury. After treating other injuries, the patient was discharged without any complications except colostomy. Abdominal impalement injuries are treated using various approaches depending on the injury mechanism and injured region. However, the most important consideration is that the impaled object should not be removed during transportation and resuscitation. Instead, it should only be removed after checking for injuries to blood vessels during laparotomy in an environment where injury control is possible.

K-Pop is powerful. Once considered to be at the periphery of global music scene, it is now reaching the whole world. Not surprisingly, the media, domestic and foreign, have scrambled to unlock the secrets of K-Pop's phenomenal growth. In doing so, they have not failed to highlight the underside of its success, such as cut-throat competition among idol-group members and the programmed member replacement by their agencies. One of the most notable characteristics in this process is called, in their business jargon, 'the graduation system'. This paper attempts to explicate this management practice unique to K-pop industry. To do so, this paper draws on Rene Girard's work on desires, particularly his notion of mimesis, violence and the scapegoat mechanism. Based on a documentary film, interactive online sites and a monograph that have chronicled how the K-pop girl group <9 Muses> have 'graduated' during their debut process, this paper applies, as its main analytical tool, the scapegoat mechanism and attempts to explore on its basis what 'the system' entails for the K-pop industry in general and the actors working within it in particular.
