Objective:The objective of this study is to evaluate affection on how users perceive colors viewed from an automotive visual display according to cultural and radical differences including North America, Europe, and Southeast Asia. This study especially aims to identify effects of the variation of tone and chroma of representative color groups by analyzing affection differences depending on cultural and racial differences targeting the colors constituted through variation of tone and chroma, centered on representative colors. Background: The colors of the menu, information display or background viewed through an automotive visual display are an important factor stimulating consumer"s affection, and therefore an effort to express the vehicle"s brand and product image through colors is made. The studies on colors focus only on the research on unique characteristics of colors, but an affective approach lacks according to cultural and racial differences on colors considering tone and chroma variation within a color from the currently used automotive visual displays. Method: To grasp the visual affection felt by users, this study extracted affective adjectives related with colors through existing literature and a dictionary for adjectives, and presented human affection dimensions on colors through evaluation of various colors. Prior to carrying out affection evaluation, the basic light sources, red (R), green (G), and blue (B) constituting the colors used for automotive visual displays were defined as a representative color group, respectively. When colors in a color group are constituted, the evaluation target of each color group consisted of the colors considering the variation of tone and chroma by changing color sense through RGB values of the remaining two light sources. And then, this study carried out affection evaluation on the constituted colors targeting the subjects with cultural and racial differences. Results: As a result of evaluating the constituted colors with representative affections, there were statistically significant differences between the groups having cultural and racial differences. As a result of S-N-K post-hoc analysis on the colors showing significant differences, North America and Europe were classified as heterogeneous groups. In some cases, Korea was classified as the homogeneous group with North America, but Korea was mainly classified as the homogenous group with Europe. Conclusion: The representative affections on colors from an automotive visual display was drawn as three affective dimensions: passionate, neat, and masculine. Based on these, the affection of Korea and Europe on the constituted colors showed significant differences from that of North America, as a result of affection evaluation on the constituted colors viewed through the visual display by reflecting cultural and racial factors. Regarding representative color groups, bigger cultural and racial differences were revealed in terms of affection on red and green colors than on blue color, and variation of affection was the biggest in the red color. Application: This study analyzed correlations of affection considering the colors constituted through variation of tone and chroma, and the culture and race in the representative color groups constituting a visual display. The results of this study are predicted to be utilized in coordination and selection of colors viewed from an automotive visual display taking into account culture and race.
Simulations Using a Whole-body Biomechanical Model

Further developments on a dynamic biomechanical model are presented to assess musculoskeltal stresses and human responses. The model being developed is an extension of the Articulated Total Body (ATB) Model, originally developed by Calspan Corp. for the study of human dynamics during automobile crashes, later adopted to the U.S. Air Force to simulate the reactions of aircrew personnel to such forces typically encountered in various phases of flight operations. Further refinements were introduced by Freivalds and Kaleps (1984) to account for a human neuromusculature. In this study, modeling of active neuromusculature was described and simulations of whole-body human motion were performed using the ATB Model. It indicated the potential of using a muscularized biomechanical model coupled with CAD capabilities to simulate human responses in a variety of industrial settings as well. This will serve as a basis of incorporating computer aided design methods into a muscularized biomechanical models.
Proper Contexts of Ergonomics and Role of Ergonomists in the Product Development Process
( Eui S. Jung ) 한국감성과학회 2014 춘계학술대회 Vol.2014 No.-
Ergonomics has been known for its diversity and interdisciplinary nature. Ergonomic knowledge comes from a vast mixture of psychology, physiology, science and engineering, which often provides us with ergonomic design principles or guidelines and it is up to us how to organize the knowledge in a proper form for the application in real fields. In the past, most ergonomists are professionally concerned with the design and evaluation of workplaces and products, focusing on human interfaces, whether they are mental or physical. Although this is still quite valid in these days, we as ergonomists are in need for better or more suitable methodologies, especially throughout the product and service development processes. In the presentation, several ways or aspects to equip us with more suitable methodologies are discussed. An introduction of other disciplines to our body of knowledge such as marketing in the context of segmentation and positioning is among them. Furthermore, ideation and creative processes need to be employed beyond the design and evaluation of existing systems for improvement. A new body of ergonomic knowledge must be formed for them to be contextually right, depending on the developmental level of companies or the type of businesses of interest because ergonomic objective must differ according to the business objective of the system development, whether it is usability, customer affection, or identity building.

최근 국내 방송 업계에서 프로그램 제작 아이디어를 쉽고 빠르게 획득하기 위하여, 방송 프로그램 포맷을 수입하여 프로그램을 제작하여 방영하고 있다. 방송 산업에서 포맷이란 일련의 시리즈물 프로그램에서 각각의 에피소드를 구성하는 가변의 요소들이 시리즈물 내내 변화지 않고 꾸준히 유지되는 프로그램 요소들의 집합을 의미하는 개념으로 사용되고 있다. 예컨대 국내에 방영되고 있는 퀴즈 프로그램인 1:100의 경우, 해외에서 포맷을 수입하여 국내에서 제작한 대표적인 사례라고 할 수 있다. 즉, 포맷이란 프로그램의 독창적인 아이디어와 구성요소를 내포하고 있는 프로그램 기획안과 유사하지만, 더 구체적인 제작 설명서에 가깝다고 할 수 있다. 본 연구는 방송 프로그램의 포맷 창작을 위하여 다수의 사용자가 창의적인 아이디어를 도출하고 확장하여, 이를 포맷 제작에 적합하게 재구성할 수 있도록 하는 시스템을 웹을 기반으로 구현하고, 이를 방송 프로그램 전문가들이 활용할 수 있도록 하고자 하는데 그 목적이 있다. Recently broadcasting production companies have imported a number of broadcast program formats to get ideas quickly and easily. The term format in broadcasting industry is defined as a paper form which includes principal elements throughout each episode of the series in a program to keep consistency. In case of the quiz program titled 1:100 which is being aired in Korea, the domestic company imported the format and produced to broadcast in Korea. In other words, a format includes components of the inherent creative ideas and proposals needed in production a program. The study proposed a web based collaborative system that many users create the format for the broadcast program together. the system is constructed to combine creative ideas to making them a format. Also, production experts will take advantage of the system.
