A site-specific performance is a genre and a phenomenon that has recently emerged as a recent paradigm of performing arts: a communality. It involves the performativity of the audience and has various phenomena of contemporary performing art. This study aims to figure out methods of performativity. "Lost Missing and Forgotten," which is a collaboration from Finland and Korea created in 2012 and "Trailer," which is held in Copenhagen Denmark in 2010 by Kitt Johnson. Three principles of performativity which have borrowed as critical tools for this study are role reversal, community building, and contact, which based on "The Aesthetics of Performativity," written by Erika Fischer-Lichte in 2017. The study results show that performativity in the vertical structure and horizontal structure of site-specific performance can act as an environmental factor through the audience's body. Additionally, it turned out that role reversal principle was transformation audience to a creator; community building principle led to an interest in neighbors. Lastly, the contact principle was one of the methods to watch the performance.

This thesis is a summary of the research result about the 20 seconds official trailer requested from the Pusan International Film Festival organizing committee. Since producing digital content is very significant at this moment, I tired to make an official trailer for 13th Pusan International Film Festival by integrating 3D animation with ink-and-wash painting. Motivated by a western-style painter, Shin Chang Sic's painting,' Arirang_HopeⅠ(An Official poster), I got to know how to express ink-and-wash painting by using digital technique and considering ink stick depth, line control and color elements for modeling, shading and rendering stage.

A hybrid control scheme is proposed for the stabilization of backward movement along simple paths for a vehicle composed of a truck and six trailers. The hybrid comprises the combination of a linear quadratic regulator (LQR) and a neurocontroller (NC) that is trained by a genetic algorithm (GA). Acting singly, either the NC or the LQR are unable to perform satisfactorily over the entire range of the operation required, but the proposed hybrid is shown to be capable of providing good overall system performance. The evaluation function of the NC in the hybrid design has been modified from the conventional type to incorporate both the squared errors and the running steps errors. The reverse movement of the trailer-truck system can be modeled as an unstable nonlinear system, with the control problem focusing on the steering angle. Achieving good backward movement is difficult because of the restraints of physical angular limitations. Due to these constraints the system is impossible to globally stabilize with standard smooth control techniques, since some initial states necessarily lead to jack-knife locks. This paper demonstrates that a hybrid of neural networks and LQR can be used effectively for the control of nonlinear dynamical systems. Results from simulated trials are reported.

In this paper, a collision accident of a container/Ro-Ro ship was numerically analyzed. A container trailer collided with a longitudinal bulkhead of the ship in the accident, which constituted a longitudinal wall of a heavy fuel oil tank. Due to the accident, the bulkhead plate was ruptured and the heavy fuel oil spilled out of the tank. The detailed information regarding the collision velocity and the mass of the trailer was not provided. Therefore, several collision accident scenarios were constructed based upon the arrangement of the ramp way. Each collision accident scenario was analyzed to predict the extents of damage using a commercial numerical package, ABAQUS. Based on the analysis results it is proposed how to minimize the extents of damage. Through the investigations performed in this study it was found that the understandings of various damages due to collision accidents and the developments of structural design guidance against collision are necessary for the betterment of Container/RO-RO ships' performance.

Jack knifing accident of semi trailer vehicle is one of the most dangerous accident type because the vehicle cross over its lane by the accident. Jack knifing accident can be predicted and detected by GNSS precise relative positioning. But integer ambiguity resolution procedure is inevitable in GNSS precise relative positioning. In this paper, success rate improving method of integer ambiguity resolution is proposed for jack knifing accident prediction and detection of semi trailer vehicle, and proposed method is tested by simulation.

To identify the driving dynamic characteristics of the Tractor-Trailer Type Transporter for mounting a large scale precision equipment, real vehicle driving tests on the 3 inch-bump-space-road were performed. And using general Dynamics Analysis Program - RecurDyn(V8R5), Dynamics M&S were carried out assuming the similar condition with real tests. Then the acceleration data obtained from real tests and M&S were analyzed and compared with each other in the part of root-mean-square-acceleration($g_{rms}$), peak-acceleration($g_{peak}$) and frequencies. In simple view of the $g_{rms}$ & $g_{peak}$, although the results of MRBD are more similar to ones of the real vehicle driving tests, but the results of RFlex have more information to get various useful dynamic characteristics.

In this study, risk assessment was conducted in case of leakage of storage facilities (tube trailer) using the HyKoRAM program developed through international joint research. The high-pressure gas facilities in the hydrogen filling station are divided into four main categories: storage facilities (tube trailers), processing facilities (compressors), compressed gas facilities, and filling facilities (dispensers). Among them, the design specifications of the tube trailer, which is a storage facility, and the surrounding environmental conditions were reflected to construct an accident scenario with previously occurring accidents and potential accidents. Through this, we identify the risks of storage facilities at hydrogen refueling stations and suggest measures to improve the safety of hydrogen charging stations.

Promotion and marketing, which are essential to lower the investment risk and maximize commercial profit in the video game market. Game developers and publishers set up public relations strategies to encourage potential consumers' needs. Considering characteristics of video game, the trailer, which is the animated image advertisement material, could occupy a key position in its promotion and marketing plan. Cinematic spectacles and attractive narratives are essential ingredients for game trailers, which are usually produced in 3D animation. Dead Island is an open world first person shooters (FPS) game released in 2011. When launched, it grabbed a great attention with a trailer, awarded the Golden Lion Prize for the best internet film at the Cannes Lions International Festival of Creativity. The game was a commercial success and several spin-offs were producted. In 2014, its publisher, Deep Silver showed the official trailer of Dead Island 2 at Electronic Entertainment Expo, the world's largest game show. Dead Island 2 was scheduled to be released in 2016, but has been now delayed until 2018. This study compares and analyzes two trailers of Dead Island 1 and Dead Island 2. We examine the narrative structure of the trailer for the sequel promotion of a successful game. The differences between the two could be useful for building a promotion strategy of other game series.

Using the dynamic model and simulation program TDA developed in the previous paper, effects of design parameters of an agricultural tractor-trailer system on its vertical seat vibrations were investigated. The tractor-trailer system was excited by traversing over a half-sine bump. The excitation frequencies were determined by traveling velocity of the tractor and a half-sine bump selected appropriately. TDA predicted the autospectra of the vertical seat accelerations with different values of design parameters and compared them to analyze their effects. The design parameters included positions of engine, cab, and seat mountings as well as their dynamic properties. The results of this study suggested guidelines with which an improved structure of tractor may be developed in the early stage of design for a better ride quality.

Train crashes involve complex interaction between deformable bodies in multiple collisions. The purpose of this study is to suggest the effective analytical procedure using hybrid model for the crashworthiness of motorized trailer of high speed train. The hybrid approach, with very short modeling times and reduced computation times to extract the global behaviour and to perform a pre-optimization of the considered structure. Firstly, various types of crash events are investigated and the conditions for numerical simulation are defined. In this paper, the structural crashwonhiness of Korean High Speed Train trailer was examined through FE analysis. Crash analyses on energy absorbing part and safety zone were carried out to determine each section force. Rollover analysis was performed to observe the amount of intrusion in the passenger's area in case of rollover accident.
