At the large commercial facilities, people try to grasp a customer's needs as the marketing strategies for effective management and maximization of profits as well as the primary purpose for functional and effective spatial plan. In planning the interior of each department, they try to provide the image of the interior environment corresponding to customer's emotional needs. And this kind of efforts also have been improved as visual merchandising strategies based on the transmission of visual information. This study is to examine the correlation among customer's behavior, circulation and VMD by gasping their shopping patterns at the department stores based on the spatial and emotional approach to form an environmental image of each department. The researcher focused on time, speed and rate of shopping that show customer's behavioristic characteristics and examine the factors to have an influence on decision making. With the result, this study proposes the primary data and evidence for MD planning, circulation planning and VMD planning of each department.

The meaning and context of objects has been changed in various ways depending on the times. Functionality of objects has been developed in various directions according to the point of view of the objects. Objects have been used as mediums to realize art in daily life, and to realize the relational forms. Based on this, it is confirmed that furniture can be an appropriate medium to articulate everyday life and to derive relational form. The 'furniture as a behavior' has the following characteristics. First, it functions to make daily life unfamiliar. By doing something unfamiliar in everyday life, users experience similar experiences as when they entered the surreal world of art museum. In this way, the possibility of everyday arts is acquired. Second, the mental and behavioral functions of furniture are continuously changed by interaction with the user. Behavior does not occur unconsciously, but involves changes in consciousness that the user intentionally does. Therefore, as the user's level of consciousness grows, personal experience changes, and the behavioral function of the household changes. The study of 'furniture as a behavior' is suggested as one approach to design furniture.

The form and function of modern museum present more a variety of aspects in need of transition of the mature civil society and culture than the past. Considering that an art museum is the space where a multitude of unspecified visitors inspect simultaneously, exhibitions and adequate construction make visitors lead to successively visual contact. Consequently a goal of this study is to analyze that there is correlation between exhibit space and exhibitions and to suggest an alternative plan at exhibition through relationship among exhibitions, exhibit space and spectators' behavior. Two Art galleries (one is a large-sized gallery and the other is a small-sized one) located in Pyung-Chang dong were selected to analyze the correlation and suggest the better display for the exhibition. The finding of the study is following. The exhibit space which spectators recognize is assumed diverse forms by an unique characteristics of exhibits and space and an arrangement of exhibitions and the path of flow of spectator who walking ahead have an huge effect on a spectators' behavior. In other words, spectators' watching patterns are affected by display of exhibitions and the path of flow. That is to say, the spectators' behavior and the concentration to watch exhibitions is decided by the exhibit form in the museum, and the quality of watching experience is depended on the spectators' relevant knowledge prior to exhibitions.

In the field of computer vision, visual surveillance systems have recently become an important research topic. Growth in this area is being driven by both the increase in the availability of inexpensive computing devices and image sensors as well as the general inefficiency of manual surveillance and monitoring. In particular, the ultimate goal for many visual surveillance systems is to provide automatic activity recognition for events at a given site. A higher level of understanding of these activities requires certain lower-level computer vision tasks to be performed. So in this paper, we propose an intelligent activity recognition model that uses a structure learning method and a classification method. The structure learning method is provided as a K2-learning algorithm that generates Bayesian networks of causal relationships between sensors for a given activity. The statistical characteristics of the sensor values and the topological characteristics of the generated graphs are learned for each activity, and then a neural network is designed to classify the current activity according to the features extracted from the multiple sensor values that have been collected. Finally, the proposed method is implemented and tested by using PETS2013 benchmark data.

PURPOSES: The urban traffic problems can be defined as general problems for smooth traffic flow including maintenance of mass transportation system according to suddenly increased population, traffic regulations for vehicles and pollution problem. As a method for solving traffic jams, one of the traffic problems of late, interest in Intelligent Traffic System(ITS) is increasing sharply, which is a system managing traffic demand by providing passers with information on traffic state of path and road conditions before they pass the road through ATIS, a field of ITS. METHODS: Variable message signs(VMS) is used on the roads as a method for providing information to promote smooth traffic flow and safety and prevent traffic accidents in advance by providing drivers with various information while driving. RESULTS: Recently, as ITS industry has been vitalized and technical factors of VMS have developed, various kinds of information is provided but the effect of VMS has not been maximized due to its limited type. CONCLUSIONS: Therefore, this study intends to provide methods for effective information transfer by analyzing driver's visual behavior characteristics for VMS and presenting a basis for maximizing VMS effect after considering read by expression type.

Russian sturgeon (Acipenser gueldenstaedtii) is commercially important in Korea because its caviar is highly prized. Although the early ontogeny of the species has been described, behavioral modifications in response to various light intensities or diel photoperiodicity patterns have not been studied extensively. The objective of the present study was to examine the behavioral characteristics of hatchery-produced A. gueldenstaedtii prelarvae over a diel photoperiodic cycle. During a diel light cycle comprising 16 h of daylight (450 lx), 4 h of dim light (10 lx), and 4 h of darkness (< 1 lx), newly hatched A. gueldenstaedtii prelarvae exhibited negative phototaxis in daylight (day 0-day 2), and this early behavior was not significantly affected by changes of light intensities. Rheotactic and non-rheotactic aggregation into schools was typical between days 3 and 6. Under the diel light cycle conditions described, rheotaxis was not influenced by environmental light intensity as much as non-rheotactic schooling behavior. Post-schooling behavior, which progressed from day 7 to day 8, did not change significantly during the diel light cycle. The data from the present study could be of practical value in developing a visual guide for assessing the fitness and quality of Russian sturgeon prelarvae under diel light cycle conditions in hatcheries.

Using non-destructive Acoustic Emission (AE) and optical Digital Image Correlation (DIC) methods, the moment-curvature behavior of steel and GFRP bars reinforced concrete beams under flexure was explored in this study. In the tension zone, laboratory studies were carried out on steel-RC and GFRP-RC beams with varying percentages of longitudinal reinforcement ratios of 0.33 %, 0.52%, and 1.11%. The distinct mechanism of cracking initiation and fracture progression of failure in steel-RC and GFRP-RC beams were effectively correlated and picked up using AE waveform characteristics of the number of AE hits and their amplitudes, AE energy as well as average frequency and duration. AE XY event plots and longitudinal strain profiles using DIC gives an online and real-time visual display of progressive AE activity and strains respectively to efficaciously depict the crack evolution and their advancement in steel-RC and GFRP-RC beams. They display a close matching with the micro and macro-cracks visually observed in the actual beams at various stages of loading.

The purpose of this study was to classify types of family visitors' behaviors more concretely, which could be useful in planning of exhibition spaces in a science museum, with given priority to their behaviors according to interaction between them, and to understand characteristics of the behaviors. With this view, the scope of this study was restricted to subjects, who were family visitors of Gwacheon National Science Museum, consisting of parents and their one elementary school child per family unit. For understanding their behaviors, itinerary tracking and observation method of behavior were conducted. Moreover, for understanding substantial types and characteristics of family visitors' behaviors, multivariate analysis was applied. Accordingly, the results of the study are as follows. First, as a result of factor analysis, two main factors were derived. In other words, they were 'Durability of viewing' as the first and 'Interactivity between family members' as the second, which were shown valid in classification of the types of their behaviors. Second, according to the factors derived, the types of their behaviors were classified into in-depth cooperative viewing, selective independent viewing, interest concentration child-led viewing and consideration parent-led viewing. They were shown valid in topological localization and classification, as a result of analysis of the main factors. Third, in view of common characteristics of the types, it is judged that active orientation prior to regular viewing could encourage visitors coming to the museum for the first time to feel more friendly to unfamiliar exhibition environments, during the initial seek time, and to reduce visual supersaturation. Fourth, it is judged that distributed arrangement of exhibits, which result in continuous standby, could avoid confused visitor circulation by the estimated time required for viewing.

This study was conducted to examine the usage effects of an augmented reality head-up display (AR-HUD) system on the risk perception and psychological changes of drivers. To do so, we conducted an experiment to collect the driver response times for vehicles and pedestrians as their risk perception behavior, and used a driving behavior determinants questionnaire consisting of Problem Evading, Benefits/Sensation Seeking, Anti-Personal Anxiety, Anti-Personal Angry, and Aggression factors for collecting the psychological characteristics of the drivers. Thirty drivers were randomly assigned into an in-vehicle AR-HUD using group and a control group. As a result, the Anti-Personal Anxiety and Anti-Personal Angry factors were negatively correlated with the response time for the control group. In contrast, these results were not shown for the in-vehicle AR-HUD system using group. These results indicate that the in-vehicle AR-HUD system may partially induce a relaxation of tension or stress for drivers with a high level of interpersonal anxiety. Therefore, the in-vehicle AR-HUD system might contribute to not only the visual safety driving behaviors of drivers, but also to their psychological driving safety with specific characteristics.

목적 : 다감각 통합은 인지과제나 운동실행을 위해 다양한 감각정보를 사용하는 데 있어서 필수적인 처리과정이다. 특히 시각 및 체감각의 통합은 운동 행동의 주요한 요소이다. 본 연구는 감각통합 과정의 시간적 경로와 뇌의 담당 위치를 파악하기 위해 신경생리학적 연구방법을 사용하여 시각과 체감각의 통합과정과 관련된 뇌의 시간적 및 공간적 특성을 조사하였다. 연구 방법 : 실험실 상황에서 시각과 촉각 자극을 독립적으로 또는 동시에 제시하고 유발전위검사(ERP: Event-Related Potentials)를 통해 통합작용 시 뇌에서 일어나는 신경세포들의 전기생리적활동을 측정하였다. 이때 시각 과 촉각을 각각 제시하여 얻은 유발전위신호들의 선형합과 두 개의 자극을 동시에 제공하였을 시 발생되는 유발전 위신호를 측정하여 비교하였다. 결과 : 시각과 촉각을 독립적으로 각각 제시하여 얻은 유발전위신호(SUM)의 합과 두 개의 자극을 동시에 제공하여 얻은 유발전위신호(SIM)는 같지 않았다. 특히나 자극의 반대측인 오른쪽 일차체감각영역(C4)에서 SIM은 SUM 보다 특정시간대에 통계적으로 유의미한 차이를 보였으며, Bilateral parietal areas(P3, Pz, P4) 뿐만 아니라 일차 시각영역(O1,O2)에서도 두 조건간 추가적인 통합관련 신경활동전기신호에 의한 통계적으로 유의미한 차이를 나타내고 있다. 결론 : 뇌 속에서 2개 이상의 감각이 통합될 경우 이와 관련된 추가적인 신경세포활동이 일어나고 있으며, 이는 다 감각을 동시에 제공할 경우 뇌의 활동을 더욱 활발하게 촉진시키고 있음을 시사한다.
