This paper sought to investigate pupil size variability, pupil size parameters in terms of time domain and frequency domain, the autonomic activity change induced by posture change, degree of sleepiness and cognitive task (math task). With a specially designed pupil image acquisition system in the dark room, these three kinds of experiments were performed to induce a dominant state of sympathetic or parasympathetic activation. Electrocardiogram and pupil size were measured in all the experiments. Based on three experiments, we calculated heart rate variability. In the pupil size analysis, we calculated the mean and standard deviation of pupil size (in time domain), and proposed several frequency bands that exhibit different autonomic activation between different sessions. The results indicate that in terms of heart rate variability, posture change exhibited significant differences but not between sleepiness level, or between cognitive task. Pupil sizes differed only during the postures. And we found some frequency bands that correlated with autonomic activation in each experiment. While heart rate variability reflects posture change that need cardiac control, pupil size variability reflects not only posture induced autonomic activation but sleepiness and cognitive load, which is processed in the brain, in time and frequency domain parameter.

Promotional videos have been increasingly adopted in social media marketing. Given that video production incurs high costs, evaluating the effectiveness of promotional videos is necessary. This research examines the effect of promotional video on visit intention through affective and cognitive destination images, respectively. Furthermore, grounded in the theoretical reasoning of social ties and persuasive intent, the effects of promotional videos disseminated by different sources (i.e., unknown users, friends, and marketers) are compared. Two experimental studies were carried out with 200 participants in Study 1 and 243 participants in Study 2. Study 1 revealed that the presence of promotional video induces visit intention through affective and cognitive destination images. Study 2 found that promotional videos disseminated by friends (versus unknown users) are more effective to induce visit intention because of positive cognitive destination image, while the video effects are indifferent between marketers and users. Meaningful implications are provided for destination marketers.

Middle age is the time of the most important meaning in life and also the time of physical and mental change, which offers new social activities for self-development. Middle-aged women form the major consumer class in current clothing industry, but few have been performed on this so far. The researcher studied in many aspect on the clothes which middle-aged women need to wear during this period of change. Thus this study is executed to examine what benefits middle-aged women pursue in clothing attitudes and the relationship among clothing pursuit benefit and their somatotype compensation and image orientation. The research performed the theoretical study and practical study simultaneously. The subjects are 238 middle-aged women between 35 and 49 years old in September, 2004. The results of this study are as follows: 1. The attitude of women's clothing patterns in relation with image consist of two factor structures. One is the body image and the other is the appearance image. 2. As a result of researching the attitude for choosing clothes of each body group by Rohrer index, the women with gross body group take a top priority for the lower-body compensation, while the women with slim body group take a top priority for volume compensation. 3. As a result of researching the cognitive somatotype group's attitude for choosing clothes, gross body group takes a top priority for lower-body compensation and upper-body compensation. 4. As a result of researching the relationship between real somatotype and cognitive somatotype by Rohrer index, middle-aged women think of themselves as being fatter than present state. And choosing the clothes, the body misunderstanding group of women usually show that they consider more compensation than the normally body understanding group. 5. The evaluation on real somatotype, cognitive somatotype, ideal somatotype influences on the body cathexis.

The algorithm is applied on the premise that the image generated by AI can be recognized and used smoothly by the user. Other assets are not exposed to the user or discarded because they are unnecessary or unfamiliar. This study aims to expand the scope of the utility of the image generated by AI, which is used as a high-level tool in the design field. To this end, we first examined human information processing and reflection in AI by the cognitive paradigm by examining previous studies and cases, and discussed the value of expansion by focusing on creativity and bottom-up processing of AI's self-organization. Considering the human recogmition process that instinctively grasps an object, the following AI usability was proposed. It is to utilize AI as a high-level tool applied appropriately to human perception, or to utilize the derivative itself by bottom-up self-organization. In addition, it is to set the algorithm to the minimum intervention so that basic elements such as shape, color, size, texture, and movement are composed of figure-ground according to the human perception process that instinctively grasps an object, and to utilize the results. Limiting the use of AI to a tool suitable for human perception and information processing or production by designers or general users is to operate only a part of the convenience and usability of AI. The image creation through AI's self-organization, as seen from the cognitive paradigm, is a step toward opening a new era of design where technical aesthetics meets devices, just as design has been constantly developing in pursuit of novelty and differentiation due to its nature.

In the process of finding the triangle height, 26 students in the 6th grade were surveyed to understand the students' triangle height through the eye movement data and to investigate the cognitive load of the students. As a result, the correctness rate of the pre-test was significantly increased in the post-test, and the frequency and retention of gaze data were smaller in the post-test than in the AOI of each question. The Participants's subjective cognitive load indicated that it was more difficult to understand the concept of rotated triangles compared with upright triangles that were parallel to the ground. More frequent and more retentions in the eye-tracking data were detected in the right triangles and acute triangles by rotating configuration. Eye movement data show that eye tracking technology can provide an objective measure of students' cognitive load for feedback on instructional design.

The tourism industry is influenced by a large number of factors that affect the development scenarios of the tourism in different ways. At the same time, tourism is an important component of the national economy of any state, forms its image, investment attractiveness, is a source of income and a stimulus for business development. The aim of the article is to conduct an empirical study to identify the importance of cognitive determinants in the development of tourism. The study used general and special methods: systems analysis, synthesis, grouping, systematization, cognitive modeling, cognitive map, pulse method, predictive extrapolation. Target factors, indicators, and control factors influencing the development of tourism in Ukraine are determined and a cognitive model is built, which graphically reflects the nature of the influence of these factors. Four main scenarios of the Ukrainian tourism industry are established on the basis of creating a matrix of adjacency of an oriented graph and forecast modeling based on a scenario approach. The practical significance of the obtained results lies in the possibility of their use to forecast the prospects of tourism development in Ukraine, the definition of state policy to support the industry that will promote international and domestic tourism.

This study aims to identify the image types of secondary school students' perception about the talented person in convergence and to find the differences in drawing images of the talented person in convergence among the students who have taken STEAM class and the ones who haven't. One hundred and eighty seven students in middle and high schools located in the southern part of South Korea participated in this study and they were asked to draw a picture of the talented person in convergence with a brief explanation. Based on students' pictures, researchers categorized their perception about convergence and talented person in convergence by using an inductive method. The result indicated that secondary school students' perceptions were categorized into convergence as individual cognitive processing and collective cognitive processing and convergence as outcomes. The image of the convergence in a talented person leaning toward individual cognitive processing was divided into the following seven types: idea banker type, various talented celebrity type, multi-tasking master type, multi-talented career type, active problem-solver type, creative developer type, and unrealistic ideal man type. Another image of collective cognitive processing was split into expert group type and interactive-mates group type. The other image was transformer type which is the subcategory of convergence as outcomes. From this study, it can be suggested that secondary school students express the various images of the talented person in convergence depending on experiencing STEAM or not.

It is very necessary to know about child recognition of residential environment to plan and design an environment proper for children's growth and development. The research method using Cognitive Map, which may be defined as "an overall mental image of representation of the space and layout of a setting" can be a good tool for studying child recognition of residential environment. This study analyzed the child recognition of the size of home range, the number of residential environment elements, the types of Cognitive Map and the levels of Cognitive Map to understand the contents of child recognition about their residential environment. Subjects were 206 children in age6, 8 and 10 in Gwanju and Jeonnam area. As the result of the study, we found that 70% of child recognized 100~500 M as the size of home range, and that the number of the elements of residential environment was 7, average. And we also found that sequential map was more popular than spatial map in child's Cognitive Map type and that almost 60% of child respondents drew the Cognitive Map of level 1 complexity type. As the result of this study, we could know that the research method using Cognitive Map was very useful for understanding the child recognition of residential environment.

The purpose of this study is to investigate the relationships between physical factors, economic factors, and cultural factors of tourism gentrification (TG) in urban areas. Based on the results of an empirical analysis, we provide the basic theory and practical implications of the relationship between tourism phenomena and city image. This study used a questionnaire for residents of the Jeju area. From September 1, 2018, to October 3, 2018, the survey was conducted in Nuemori Street, Yeongdong Street, Gucheong Eup, and Moon Town. Thus, we use 479 samples for analysis out of 500 samples obtained. This study produced two important results. First, the physical, economic, and cultural factors of tourism gentrification have significant effects on cognitive image and emotional image. Second, economic factors have statistical significance in cognitive image and emotional image. These results and implications can be useful for practical implications of the theoretical implications of tourism gentrification and regional specialization promotion policies. In addition, from the economic point of view, what should be considered is that development-centered area development can have a negative impact on urban image. Despite these research results, there are limitations in the research, such as cross-sectional studies and short-term studies, and we look forward to a longitudinal study in the future from a long-term perspective.
