본 연구는 자연성 정도를 달리한 산악조망경관에 있어 각 공간별 형태적 특성이 지니고 있는 이미지 및 시각 선호도를 구명하여 차후 공원관리 및 설계시 기초자료를 제공하기 위해 한라산 성판악 등산로 상에서 촬영한 사진자료를 평가매체로 하여 자연도에 따른 이미지와 선호도를 조사분석 하였으며 그 결과는 다음과 같다. 선호도 평가치는 자연성 정도 및 포장의 재료특성 등의 영향으로 정상부로 향할수록 크게 상승한 것으로 나타났다. 등산로 변 이미지 평가는 아름답고 매력 있으며, 깨끗한 이미지가 주류를 이루고 있었다. 인자분석 결과 4개의 인자군은 각각 ${\ulcorner}$경관매력도인자${\lrcorner}$, ${\ulcorner}$공간스케일인자${\lrcorner}$, ${\ulcorner}$자연성인자${\lrcorner}$, ${\ulcorner}$지형지세 인자${\lrcorner}$라고 명명 분류되었으며 전체 변량중 이들 인자군의 설명력은 57.6%이었다. 자연도와 명명 인자별 관계에서 각 공간별 인자점수의 평균치 변화 결과 자연도가 증가하면 할수록 경관매력도차원의 인자점수 값이 낮아지는 경향을 보여 미적 인 감각과 시설물의 수에 상관성이 있을 것이란 판단이 가능할 수 있을 것으로 생각된다. 또한 시각선호도 모형 분석 결과 경관매력도차원의 인자가 시각 선호도에 가장 큰 영향을 미친 것으로 나타났다.

The purpose of this study is to evaluate the differences of visual image by variations in the location of the waistline and the width of the round belt of the basic pants. The stimuli are 21 samples: 7 variations of the location of the waistline and 3 variations of the width of the belt. The data has been obtained from 35 fashion design majors. The data has analyzed by frequency, factor analysis, anova, scheffe's test and the MCA method. The visual image by the location of waistline and the width of belt are composed of 3 factors : modernity, comfort and attraction factor. In these factors, modernity factor is estimated as the most important factor. The visual image is modern and attractive as the location of waist line goes down. And when the location of waist line is in the position of natural waist belt, belt of 3.2cm width is visually effective. Belt of 4.2cm width is effective except the position of natural waist belt. The interaction effects between the location of the waistline and the width of the belt have significant differences in comfort and attraction factors. As the main effect, significant differences were observed in all of the three factors according to the location of waistline and the width of belt.

Online shopping is increasing worldwide. Providing customers actual feeling of the product is essential in online shopping. Various technological aids can be used to support visual feeling. When delivering visual tangibility, it is important to study which attributes are significant in product presentations that best portray the actual tactileness. In this perspective, we suggest 'visual tactility' (VT) as a parameter for delivering tangibility in visual presentation. By measuring visual tactility in different product types, latent factors of visual tactility were identified and their influence on purchase intention was determined in this study. We defined material properties of touch such as surface texture, hardness, temperature, and weight as Visual Tactility (VT), the influential factor of tactility. We investigated the influence of VT on product purchase intention and analyzed tactileness within four online product presentations: single static picture, multi static pictures, zoom, and video. Our purpose was to investigate underlying effects of visual tactile attributes on touch and determine their influences according to online product presentation formats. Our results showed that visual tactility positively affected purchase intention and that each attribute differed in importance according to product type. Moreover, this study revealed a strong relation between online product presentation and VT attributes. These results provide a guide when selecting which presentation is optimal for delivering a product's tactility in online shopping situation.

This study aims to develop three types of the visual fields: stationary field, eye field, and head field, which are classified depending upon the eye and head movements. A visual experiment taking target size, target color, and meridian into account was conducted, in which the L32 orthogonal array was employed. The results showed that target size and meridian were significant at ${\alpha}$=0.01 in all three visual fields. Contrary to expectation, target color was significant at ${\alpha}$=0.10 only in the head field. Furthermore, the differences in size of the head field depending upon four target colors were negligibly small. Three linear regression models were provided to generate visual fields which are appropriate for given visual task's characteristics. In addition, a simple method using adjusting factor was also proposed so that anyone without knowledge for human factors/ergonomics can easily generate and use them when designing or evaluating visual tasks. It is expected that the visual fields presented in this study can be easily used even by non-ergonomic experts in real situations due to their simplicity.

Objective: This study examined the construct validity of K-WPPSI-IV. Factor structures of the structures of the K-WPPSI-IV full scale as well as primary index scales for two age ranges (2 years, 6 months to 3 years, 11 months; 4 years to 7 years, 7 months) were examined. Methods: Data were collected from 1,700 children aged 2 years, 6 months to 7 years, 7 months during the K-WPPSI-IV standardization. Confirmatory factor analyses were conducted using the K-WPPSI-IV subtest performances with maximum likelihood estimation using Amos 18. Results: First, the three-factor model (verbal comprehension, visual spatial, and working memory) fitted best for the younger age range. However, the five-factor model (verbal comprehension, visual spatial, fluid reasoning, working memory, and processing speed) fitted best for the older age range. Residuals suggest the presence of two nested subfactors within the verbal comprehension factor (broad/expressive and focused/simple). Second, the confirmatory factor analysis on primary index subtests identified factors that account for the intercorrelations among the reduced sets of primary index subtests. Conclusion: The findings showed that the theoretical structures of WPPSI-IV subtests were confirmed within K-WPPSI-IV.

This study investigated the influential range of landmarks and the relationship between landmarks and cognition factor so as to offer basic data to be used for the effective use and the management of landmarks. In this study, eighteen famous landmark in Seoul were selected and analyzed. The result of this study can be summarized as follows : 1) First, eighteen determining elements of cognition factors were selected via documents survey. Second, general cognition factors of landmarks were analysed using these elements through questionnaires to specialists. As a result of factor analysis, historic cultural factor, scale factor, visual form factor, locational factor and uniqueness factor were revealed. 2) According to revealed cognition factor, eighteen landmarks are categorized into four types using MDS method via questionnaire to resident in Seoul city. These four types of landmarks are: type I that are recognized by historic cultural factor; type II that are recognized by scale factor; type III that are recognized by uniqueness factor; and type IV that are recognized by visual form factor. 3) As the result of regression, the influential range of landmarks were revealed at about a 10km radius(type I : 12km type II : whole area of Seoul city≒15km, typeIII : 8.7km, typeIV : 8.5km). 4) As a result of analysing the correlation between the influential range and the cognition factor through multiple linear regression analysis, the locational factor is the main factor affecting the influential range of landmarks in every type. The uniqueness factor comes next, which affects influential range partially. 5) Except type 1, as a result of analysing the correlation between influential range and the physical heights of landmarks, a quadratic equation is revealed, showing that the influential range of landmarks over 200 meters in height shows a radical change. Landmarks can be used as reinforcement tools of legibility, effective tools for landscape management and for the improvement of a community's image. This study on the influential range of landmarks and main cognition factor can be utilized as a landmark management plan and in urban planning, such as a new town plan.
