Satisfaction of consumer preferences is a key factor for the success of the products. Therefore, design mangers try to develop the profitable products through the intensive survey on the consumer preferences. Although the studies on the preferable product design and the design factors have long been carried out, most of these studies dealt only with the design factors preferable for individual product category ignoring the relationship of the product categories which are related to each other. For designers and design managers, in this study, we propose the guidelines of successful product development by finding preferred common and distinct design factors through analysis of the relations between the consumer preferences and design factors in various portable electric devices. To this end, we analyzed the preferred common and distinct design factors from portable electric devices including the electronic dictionaries, notebook computers, cellular phones, and MP3 players. We used hierarchical regression analysis for the effects of the design factors on the preferences among the product categories and regression analysis for the effects among each product category. The analysis on the preferred common design factors among the four product categories revealed that consumers did not care about the whole body type but preferred white color, metallic and glassy texture in the body. Also, the preferred design factors in the each product category are as follows; oval body shape and black color in electronic dictionaries, white color, metallic and glassy texture in notebook computers, plastic texture in cellular phones, rectangular body shape and plastic texture in MP3 players. In the case of notebook computers, the preferred common and distinct design factors were the same. We expect these results will be helpful for designers and design managers to identify the preferred design factors to consider when developing the various portable electric devices.

The purpose of the study is to investigate the influence of Ring-Back-Tone(RBT) music on the evaluation of the phone-call receiver`s personality in dimensions of Openness, Extroversion, and Neuroticism. In a preliminary test, the subjects listened to 17 RBT music stimuli in random order and assessed the personality associated with liking for each music(N=15). Among the 17 RBTs, three were selected to be used in Experiments I and II and they were distinguished from each other in terms of the three personality dimensions(p<0.001). In Experiment I, the subjects were divided into four groups and were asked to make a call to interview an unknown receiver(N=60). Different RBT music was installed depending on the group to which each subject belonged. It was found that different RBT influences the caller`s evaluation of the receiver`s personality, supporting Hypothesis 1(p<0.001). Moreover, the ratings of the receiver`s were highly correlated with those of the RBT music stimuli in terms of Openness(r=0.722, p<0.001) and Extroversion(r=0.753, p<0.001). In Experiment II, an identical experiment design was applied for a new group of subjects who were acquainted with the receiver(N=40). It was hypothesized that previous knowledge about a person would weaken the RBT effect. The results showed that RBT exerted no effect on the evaluation of the receiver`s personality when the caller knew the receiver. It was also found that 12 personality traits, where each of the three personality dimensions is described by four traits, facilitated assessment of the character of the RBT music as well as the personality of the receiver.

This study aims to characterize the effect of different combinations of chromatic-achromatic colors and area-ratio of stripe necktie, and gender on the image of male wearer. The experimental materials developed for this study are a set of stimuli and response scales. The stimuli consist of 84 color pictures manipulated with every combination of 12 different colors and 7 different area-ratio. The 7-point scale designed for visual evaluation of image formation included 26 bipolar adjectives. The subjects were 2016 undergraduate students in Gyeongnam, Seoul, Busan, and Daegu areas. The results of this study were as follows.; The analyses of images of male wearer in terms of combinations of chromatic-achromatic colors and area-ratio of oblique stripe necktie reveal that the concerned factors are of five characteristic dimensions of youth-activity, ability, attractiveness, appeal, and warmness. In addition, it has been found that individual images of male wearer are affected by observer`s gender as well as combinations of chromatic-achromatic colors and area-ratio of stripe neckties and that those images vary with every combination of each factor. The study results are highly expected to be used as useful sources in developing necktie designs.

The purpose of this research was to identify the difference between expected and actual corporate image in the market and to verify the possibility of green-oriented corporate identity (CI) visual design as a useful method for communicating with consumers. In addition, this research suggests how green-oriented CI visual design can effectively convey corporate image to consumers. The methods of research used to achieve this aim were case studies and questionnaire surveys. In regard to the results, the difference between consumers` perceived favourable corporate image and companies` expectation about corporate image was found. Moreover, the results show that green-oriented visual identity (VI) design can improve corporate image. In turn, the gap between the expected and actual perception of corporate image can be decreased through green-oriented design. Based on these results, a method of effective development for green-oriented VI design is recommended.

This study is to find training effect on EEG(Electroencephalography) and EMG(electromyogram) evoked by repetitive movement of a hand. Five university students participated in this study and were asked to perform repetitive movement of right hand for 5 seconds with rest for 10 seconds. They repeated the movement for 48 minutes and for 5 days. EEG and EMG were measured according to every movement. Coherence between EEG and EMG and power spectrum of EEG were analyzed and were tried to observe their changes within a day and between days of the repetitive movement. Training effect according the time of the movement was significantly found in mu and beta frequencies in EEG. However, training effect was not significant between the days of the movement and also, not in coherence between EEG and EMG.

Using flight simulator tasks with 48 air force cadets, this research examined the effects of pilots` flight skill and self-esteem on risk-taking behavior in the context of social comparison with their cohorts. Flight skill and self-esteem were assessed for individual cadets and three conditions of social comparison (upward-, downward-, and no-comparison) were devised. Flight simulator situations inappropriate for further approach or landing were designed to assess pilots` risk-taking behavior. Weather conditions in the simulator were inadequate to make a landing and the recommended strategy was to break off the approach and attempt a go-around. In this experiment, pilots` risk taking was measured in terms of their approach altitudes; the lower approach altitudes indicative of the higher risk-taking. Our results showed interaction effects of flight skill, self-esteem, and social comparison on risk-taking behaviors. For pilots who were either high or low in both self-esteem and flight skill, social comparison had no effect on risk-taking behavior. However, pilots with high self-esteem but low flight skill showed more risk-taking behaviors in social comparison conditions. And, pilots with low self-esteem but high flight skill showed risk-aversive behaviors in the downward-comparison condition.

This study intended to grasp image association on human`s product and cognition response characteristic, and analyze their correlation with product preference. For this, photos of mobile phones and proposal-type products were selected for experiment stimuli, and an experiment expressing associated word and an experiment evaluating preference of each product`s photo were made. With the experiments, two results were derived. First, in linguistic cognition response on product with use experience, application of emotional expression increased as the level of preference increased by mixing expressions of metaphor languages and emotional image. Second, non-use experience of product induces response corresponding to understanding on the object of cognition only perceptually and considering similarities with general experience information.

The paradigm of a product taking a sudden turn of technical development is due to a change of the needs of diversified user, and this shows that users emphasizes on the value of the sensitivity than the standardized form and usableness of the product, and the value of such a sensitivity can relate to the needs of the product, and it can be filled up eventually by the rapid completion of the product. The creativity will be the most important ability in the future society, it is an added value to all the profession workers which people can use that to increase their competitiveness ability. It is recognized the value of the sensitivity represents the feels psychological aspect of the user and it would be the future design trend, by doing this, products designed would be different from the existing products in the market. I am going to show you that this can be used in the design concept derivation process, there is several core design elements in the product development process, these elements can not only represent the basic user needs but also the user inner unconscious needs, at the same time it keeps the aesthetic concern.

This research investigated differences of perception ratio and processes of memory reconstruction. To examine the differences in perception for positive or negative events related to individual subjective well-level, 199 participants were asked to report the perceived ratio of positive versus negative events for the provided event list. Also, recall differences of positive versus negative events were examined in relation to individual differences in happiness. Results partially supported the hypothesis that happy people perceive more positive stimulus in a given situation than less happy people. Happy people also showed more positive percentage in recalled events than actual ratio while unhappy people reported less positive recall percentage than actual ratio. These findings indicate existence of cognitive process that enhances positive or negative memory related to subjective well-being. Significant correlation between perceived ratio and recalled ratio further supports this proposition. Finally, theoretical implications of the present research and suggestions for future research were discussed.

In order to develop “textile electrode-sensing clothing” which is a sort of smart clothing to measure electric activities of heart, we propose possible ways to develop textile electrode and design of sensing clothing, ultimately aiming to develop “ECG sensing clothing for lifestyle monitoring”. Conventional sensors for measuring typical electric activities of heart keep certain distance between measuring electrodes to measure signals for electric activities of heart, but these sensors often cause inappropriate factors (e.g. motional artifacts, inconvenience of use, etc) for monitoring natural cardiac activities in our daily life. In addition, most of textile electrodes have made it difficult to collect data due to high impedance and unstable contact between skin and electrodes. To overcome these questions, we minimized distance between electrodes and skin to maximize convenience of use. And in order to complement contact between skin electrodes, we modified textile electrode`s form and developed ways to design clothing. As a result, we could find out clinical significance by investigating possible associations of clinical electrocardiogram (ECG) with variation of distance between electrodes, and could also demonstrate clinically significant associations between textile electrode developed herein and clothing.
