The purpose of this study is to identify the differences in persuasive effectiveness of visual merchandising according to merchandise class. For the experiment, 8 stimuli brands were selected. A total of 360 questionnaires were obtained from college students. The results were as follows. First, VM cognition were divided into 3 factors by confirmatory factor analysis: coordination, attractiveness, and function. Second, coordination and function had a positive effect on brand attitude. Third, brand attitude had a positive impact on brand loyalty. Fourth, it was revealed that merchandise class had a moderating role in the influence of VM cognition on brand attitude. This study has a meaning in that the theoretical extension of previous studies on VM was executed and demonstrated the moderating role of merchandise class when brand attitude was formed by VM cognition.

In these days, the technical advances and complexities have generated much of the difficulties in managing the project resources, both time and costing to accomplish the project in the most efficient manner. The project manager is frequently required to render judgements concerning the schedule and resource adjustments. This research develops an analytical model for a schedule-cost and risk analysis based on visual PERT/CPM. We used a two-step approaches ：in the step 1, a deterministic PERT/CPM model for the critical path and estimating the project time schedule and related resource planning, In the second step, we developed a heuristic model for crash and stretch out analysis based upon a time-cost trade-off associated with the crash and stretch out of the project. Computer implementation of this model is provided based on GUI-Type objective-oriented programming for the users and provided displays of all the inputs and outputs in the form of visual graphical. Also developed GUI-type program, Dongeui Visual-PERT/CPM. The results of this research will provide the project managers with an efficient management tool.

In this study, an experiment was conducted in order to investigate the feasibility and effectiveness of and on-line subjective assessment (OLSA) system. The present study compared Galvanic Skin Response (GSR) with the OLSA by presenting 28 subjects in their 20s with pictures arousing either positive or negative sensibility. According to the correlation coefficients, changes in subjective sensibility caused by the positive visual stimulus were related more closely to GSR, from the positive visual stimulus, and changes in subjective sensibility caused by the negative visual stimulus were related more closely to GSR from the negative visual stimulus. In conclusion, the most remarkable characteristic of the present system is that it not only assesses the average sensibility when stimuli are presented, but also shows the changing strength of sensibility over time.

This paper presents a development of the control and the virtual reality visual system for a tilting train simulator. The user of the tilting train simulator is able to set up the environmental and operating conditions through the user interface provided by the control system. In the control system, an arbitrary track which has user-defined curve radius, length and direction can be generated. The virtual reality visual system provides an artificial environment that is composed of several facilities such as station, platform, track, bridge, tunnel and signaling system. In order to maximize the reality, all of the 3D modeling were based on the real photographs taken in the Jungang line. A dome screen with 1600mm diameter was used to maximize the view angle. The hemispherical screen can ensure the view angle of the 170 degrees of vertical direction and 135 degrees of lateral direction.

In this paper, we propose a robust controller for motion control of n-link robot manipulators using visual feedback. The desired joint velocity and acceleration is obtained by the feature-based visual systems and is used in the joint velocity control loop for trajectory control of the robot manipulator. We design a robust controller that compensates for bounded parametric uncertainties of robot dynamics. The stability analysis of robust joint velocity control system is shown by Lyapunov Method. The effectiveness of the proposed method is shown by simulation results on the 5-link robot manipulators with two degree of freedom.

While transparency in general refers to the structure that is optically luminant or pleasant in its lightness, it is often synonymous with the concept of "modernistic." The advancement in construction and design technologies and the development of new materials with versatility adds even further diversity to transparency in architectural expression. The purpose of this study is to analyze various conceptions about transparency effects by comparing diverse expressions of visual lightness effects in space design. For this, I categorize and exemplify visual lightness effects of space applied to transparent materials. I argue that by utilizing transparent materials, the perception of space as well as boundaries between exterior and interior can be profoundly transformed. Space that overlaps through transparent boundaries creates atmosphere which deepens the architectural space environments.ironments.

본 연구에서는 광원의 색온도와 연색성의 차이에 의한 밝음의 느낌을 연구하기 위하여 이종 램프간, 또한 동종 램프 간의 비교 실험을 시각 대상물로 흑백 인쇄문자지와 색상지를 사용하여 수행하였다. 백열전구, 형광램프, 고압 나트륨램프, 메탈헬라이드램프, 무전극 방전램프를 대상으로 실험을 수행한 결과, 이종 광원의 경우 밝음의 느낌 비는 백열전구를 제외한 광원의 경우 대체적으로 평균연색계수에 비례하는 경향이 있으며, 모든 시험 대상 광원의 경우 색온도에 비례하는 것으로 나타났다.

The purposes of this study were to develop a forest landscape assessment technique for landscape ecological planting and urban forest management. The study was conducted by 4 steps in a case of "Inwang Mt.", Seoul. The process and results of the study are as follows : 1. The vegetation types of the Inwang Mt. were identified. 2. The 19 visual types from the vegetation types were classified. 3. The visual preference for the classified types was evaluated. Sorbus alnifolia community, Sorbus alnifolia community-Robinia pseudoacacia group, etc. were highly preferred. 4. A voting distribution graph of each visual type and an ecological -visual assessment map were developed. Finally the applications of the study were suggested.suggested.

The progress of urbanization has been accelerated by the development of machinery after the Industrial Revolution and the speed of change has been increased after the invention of computers. However, the problem of residence, the space for human life in the city, is still not complete. Ever since apartments rose as a solution for the residential problem caused by urbanization after the 1970s and now after 30 years, remodelling is preferred among the 2 choices, reconstruction and remodelling of apartments, in respect of economy and efficiency. Especially, in remodelling collective residence, construction, equipment environment, sight, etc. are considered and only after testing these various aspects can remodelling succeed. Aiming at studying the need of visual identity among many considerations in remodelling, this study investigates and analyzes the remodelling cases of domestic and overseas common residence and suggests the need of visual identity. In Korea where construction design for common residence is monotonous, expressing visual identity can be even more important. The common residence area that symbolizes its unique characteristic will elevate not only its economic value but also the psychological value of its residents.
