  • The purpose of this research is particle shape evaluation of aggregate using Digital Image Process(DIP). DIP is very useful to measure the roughness and particle shape of aggregates. Couple of aggregates, like standard sand, two different crushed stones, and two different marine aggregates, have been employed. Shape factors of two different marine aggregates are ranged 0.35 to 0.54. Crushed stone I is 0.74 which is highly flat, but standard sand is elongated shape. Especially, two marine aggregate showed a big difference of width and length which meaned a long shape. There is any significant difference of elongation ratio and flatness for each aggregate with different measuring system, like direct measurement of vernier calipers and DIP method. Shape conversion coefficient and equivalent diameter for changing 2D image to 3D image by the Digital Image Process(DIP) have been suggested and modified particle size distribution curve has been showed. The measured flatness ratios of each aggregate were 0.30, 0.36, 0.47 and 0.83, respectively. Also, the conversion shape coefficients of each aggregate were determinded as 0.77, 0.78, 0.84 and 0.92. The size of aggregate has been modified by multiplying the shape conversion coefficient and the aggregate size from DIP. The modified gradation curve with modified volume and weight of aggregate has been suggested. Within the limited test results, DIP is one of useful to get the particle shape of aggregate with limitation of measuring errors and to apply the particle distribution curve.

  • Although Rotoscoping technique has been used for a long time to mimic the natural and smooth motion since the early 20th century, its artistic value was devalued as tricks because it traces the already recorded images. But the fact that the rotoscoping images can cross the boundaries between animation and live action in an infinite integral freedom in the digital era became rather expansive new aesthetic possibilities of representation of the reality. In addition, Jonas Odell's animations such as (2010), (2008), (2006) are good example to prove that the rotoscoping images also can serve as means to enhance its narrative. This study is to analyze how rotoscoping images act as a unique role in relation with the narrative based on the said person's real stories and realistic images. I argue that his animated films constantly contain these three characteristics -Images to mediate Auditory sensitivity as a record of inner metaphysical reality, anonymous images to represent a specific existential character, and images that act as physical representation that holds the physical space/time and related memory. This reveals that rotoscoping images in this digital era went beyond reproduction for natural movements or special type of style. It rather suggests new layers of experience, and acquires new value in animation. I hope that this study could serve as a foundation to rediscover and re-position the value of rotoscoping images as well as good opportunity to introduce very talented swedish animation artist who already received global attention with his unique philosophical and aesthetic style.

  • 디지털 영화의 핍진성은 인지적 균형과 밀접한 연관성을 가진다. 이것은 이미지를 통해 균형을 이루기 위한 끊임없는 인지의 과정이다. 그러나 인지적인 균형을 중심으로 디지털 영화의 핍진성을 연구한 문헌은 부족한 상황이다. 이에 연구자는 인지적인 균형과 디지털 영화의 핍진성이 디지털 영화에 끼치는 영향에 대해 분석하고자 한다. 이를 통해 디지털 영화에 대한 폭 넓은 연구의 가능성을 제기하고자 한다.

  • Image synthesis has been remarkably developed in the computer vision domain and various researches have been proposed to generate realistic and high-resolution images. In particular, image-based virtual try-on is an application in fashion domain to simulate wearing clothes. Specifically, using input images of a fashion model and products, an realistic image of the model wearing the provided garments is synthesized. In this paper, we present a comprehensive review of technical trends in image-based virtual try-on technology. We first introduce relevant datasets and discuss their characteristics. Then, we categorize existing image synthesis methods into three main streams: warping-based methods, encoding-decoding-based methods, and diffusion-based methods. Finally, we explore other important research issues in the field of virtual try-on and analyze related researches aimed to tackling those challenges.

  • In order to attain 'reality', technology, style and narrative have developed throughout the history of cinema. The projection of digital image necessitated a new perspective beyond the conventional relationship between film and reality. In the SF film, DISTRICT 9, strong realism elements are evident despite its genre. Advanced technologies enabled the digital images to vividly reproduce the realm of imagination. The encounter of the realistic approaches embedded in the style and narrative with the digital images emphasizes the social context of the cinematic background, as well as extending the potentialities of verisimilitude and perceptual realism. The amount of freedom in editing process derived from this film's documentary-like style opened a possibility for the effective delivery of the vast information-furthermore contributing to the realism of the film by encompassing the diversity that exists in the reality.

  • The changing paradigm due to the emergence of smart phone and the rapid spread of internet-based social media usage is considerably impacting the politics, economy, society, culture and many other fields. As the new communication tools, social media is receiving spotlight for its advantage of low cost but high efficiency. With the accelerating of the fulfillment of knowledge-based economy, country image is more and more recognized as the core competitiveness of a country. Therefore, it is very important to grasp the factors that affect country image. In this study, a literature review on the factors provided was conducted and affecting factors on country image were analyzed. In addition, on the assumption that social media, which are widely used on current days, have meaningful effects on country image and purchasing intention, features of social media are added as variables and analyzed. The results of analysis show that social media has meaningful effects on the country image and purchasing intention.

  • The purpose of this study was to investigate the relationship between clinical practice stress, practice satisfaction, and nursing image of nursing students with experience of Gerontological nursing practice and to identify factors affecting nursing image. Data were collected from 150 nursing students from September 1 to 23, 2016 and analyzed using SPSS / Win 23.0. Results showed, practise stress was 3.13, satisfaction, 3.14 and nursing image, 3.32. Correlation analysis revealed that there was negative correlation between practice stress and practicec satisfaction, practice stress and nursing image, and a positive correlation between nursing image and practice satisfaction. Meanwhile, the factor affecting nursing image was practice satisfaction (${\beta}=.602$) and the explanatory power was 40%. Therefore, effective nursing education and practical strategies are needed to improve the nursing image and practice satisfaction of Gerontological nursing practice of nursing students.

  • As the film industry develops in China, movie posters come in various types. Among them, 'concept poster' has been recognized as an important means to form the first impression of a movie at the early stage of promoting the movie. In China, however, there are not many movie posters that have been recognized for their creativity. Accordingly, it calls for research on creative methods of implicitly expressing the content of the movie. This study analyzed visual expressions in the concept posters of HuangHai, who has been recognized not only for commerciality but also for artistry. The results showed that he did not use images of famous scenes and actors in the movie. Instead, he created the implicit image that reflects the main theme of the movie by using Minimalism, color, typography, and pictorial images. This study has a significance in terms of providing fundamental resources for improving movie poster designs in China.
