Despite the attention regarding the effects of brand extension, there is limited research focused on brand extension in the beauty industry. This study discusses whether the similarity of extensional types and brand fit has any effect on the brand attitude toward beauty brand extension. This study examines the changes in the brand attitude and finds the effect of the similarity of extensional types and brand fits on brand attitude toward beauty brand extension. In the experiment, 4 description type factorial designs were performed. A total of 114 females participated in the experiment that had an experience of visiting a beauty salon. The results are as follows. First, the similarity of an extensional product-type has a positive effect on attitude toward parent beauty brand, while the similarity of extensional service-type does not. Second, there are significant independent and interaction effects between similarity and brand fit, which reveal differential influences on attitudes toward an extended beauty brand. Attitudes toward parent and extended beauty brands were affected by the similarity of extensional types and brand fit.

The purpose of this study is to verify how similar the virtual fit pants are to the actual fit of stretchable pants. Data is produced using a virtual model to apply movements. The results show that in the upright position, the similarity between the appearance of the actual fit and the virtual fit is high. Results are 4.47, 4.13 and 4.33 out of 5 on the front, side, and back, respectively. The base line of the front and back, and the amount of allowance in each part were well reproduced by the model. The texture of the virtual fit was evaluated and found to be similar to the actual fabric. In terms of shape and number of wrinkles with the virtual fit pants, large wrinkles were better expressed than fine wrinkles. After applying movements to the virtual model, the front and side results were similar to the actual fit, but the back results were different. As a result of multiple comparisons, the greatest difference in similarity by movements is found in the center front line. The similarity difference was lower on the side than on the front. The only significant difference after applying movements is in the hip circumference margin. According to movements, the similarity of virtual fit is lower on the back than on the front and side, and the back also has the largest similarity differences to the movements type.

The purpose of this study was to compare the similarity between actual and virtual pants using a virtual 3D CLO program. A subject corresponding to the average size of a women in her twenties was selected and an avatar with the same specifications was produced. Silhouettes of the pants were classified into trousers, slacks, and wide pants and images of actual and virtual pants were evaluated from the front, side, and back. The results were as follows: Overall, the resemblance of the trousers was evaluated higher than that of other pants. The average similarity of trousers was 4.20 at the front, 3.98 at the side, and 4.17 at the back, which was much like the actual clothing. In contrast, that of the slacks was 3.62, 3.73, and 3.79 and of the wide pants was 3.81, 3.53, and 3.97. The similarity between the actual and virtual clothing was relatively well reproduced when the shape of the pants was like the silhouette of the human body. However, if the pants were tight or loose, virtual fits failed to display the wrinkles caused by the tightness or the excessive slack. The virtual fit showed fewer wrinkles and did not depict the location and the shape of hemlines as accurately as the actual fit, although virtual fits adequately displayed the baseline and dart on the pants.

Several retailers such as Target and Kohle's and their vendors have piloting the 3D clothing simulation programs to produce garment samples. However, few studies have verified the virtual fit information and 3d visualization process for pants, and no study compared the commercial 3D virtual programs. This study is designed to analyze similarity of fit and appearance between real pants with 3D virtual pants based on three 3D virtual programs (Optitex, CLO 3D, and i-Designer), three lower body types (slim, normal, and thick waist type), and fit status. We selected a representative model for each lower body type, produced their custom pants according to Lee and Nam's method(2007), and took photos of front, side and back view for visual analysis. Then, we virtually tried each model's custom pants on her parametric avatar developed by manually inputting their body measurements using the three 3D virtual program. Thirty fit experts compared the real fit to virtual fit. This study found that 'Optitex' and 'i-Designer' can visualize more effectively than 'CLO 3D' in many fit locations. Regarding the body types, 3D virtual program can visualize pants fit for 'thick waist body type' more preciously than the other body types. With respect to fit status, it does not affect much on the similarity overall.

This study is designed to analyze the similarity of fit and appearance between 3D virtual torso length sloper with real torso length sloper according to three 3D virtual clothing simulation programs (Optitex, CLO 3D, i-Designer), three body types (A, N, H) and fit status. We selected three representative body type models of females aged 20~30 and got their direct body measurements. Using these body measurements, we developed three 3D avatar body models and made three torso length fitted sloper with long sleeves. Thirty expert fit judges consisting of technical designers and graduate students assessed the similarity of fit and appearance between 3D virtual clothing and real clothing by observing images classified into front, back and side scene. We conducted ANOVA and post-hoc analyses to compare fit and appearance between real clothing and virtual clothing depending on three program. The results showed that CLO 3D represented fit and silhouette most similarly among the programs, especially girths, width and length. i-Designer tended to be relatively good to represent stress fold amount and silhouette. Optitex was assessed relatively better in expressing ease amounts in torso girths and armscye girths, but relatively worse for width, length, stress fold amount and silhouette.

Corporate Social Responsibility (CSR) activities are important tool in corporate management strategies. However, the way that companies conduct CSR activities might bring different effect on consumers. The purpose of this study is to verify the effect of CSR fit (similarity between the firm's CSR activities and the firm's core products or technologies) on the consumers' evaluation on product performance. In addition to the main effects of CSR fit on perceived product performance, and we also examined how this effect changes when CSR information source and consumer expertise are involved as control variables. Study 1 of this research was conducted with US consumers and study 2 was with Chinese consumers. Experimental results show that consumers' perceive product performance is better when the fit between CSR activities and firm's core products or technologies is low than the fit is high. When CSR information sources are neutral sources, consumers perceive product performance to be better when the fit between the firm's CSR activities and the firm's core products or technologies is low than the fit is high. However when CSR information was delivered by company's source like nadvertisement, such difference disappears. This study also show that the higher the customer's expertise, the better the product performance was perceived for high-fit CSR activities. On the other hand, the lower the consumer's expertise, the better perceived product performance was perceived for low-fit CSR activities.

This study aims to verify the sewing technology and the expression of the virtual garment program by comparing the appearance similarity between the real and the virtual power shoulder jacket. To this end, the H and the X silhouettes of the power shoulder jacket were selected as the reference designs. After making the reference designs into real jackets by applying the human body dimensions of women in their twenties, virtual avatars and jackets were produced using CLO 3D programs. The results showed that the H-type with only expanded shoulders and less design variation had a high similarity between the reference photo and real garment, the real and virtual garment, and the reference photo and virtual garment. The power shoulder jacket of the reference picture was well reproduced in the real and virtual garments. Conversely, the X-type jacket, which is a tight fit and has many design variations, showed somewhat low similarity in the circumference items and the basic construction line. Especially in tight-fitted power shoulder jackets, the fact that shoulder angles and the essential items for pattern making cannot be reflected in reproducing virtual models was found to be a limitation in increasing the similarity of virtual clothing. Furthermore, the sewing system gap between the real and the virtual clothing exposed a difference in the appearance of virtual clothing.

Based on the Construal Level Theory, we aim to study a most favorable fit among the advertising model, media type, and message construals, which are important factors in an advertisement. A two (social distance of the ad model in an ad: distal (low similarity) vs proximal (high similarity) by two (social distance of a media type: distal (portal) vs. proximal (SNS)) by two (message construal: abstract vs concrete) laboratory experiment was conducted to examine attitude changes on ad messages. The results show that abstract messages were more effective in attitude toward advertisement and purchase intention under the distal social distance (i.e. advertising model in low-similarity and portal media type) while concrete messages were so under the proximal social distance and SNS media type.

협력 필터링은 상업적 추천 시스템에서 널리 사용되어 왔는데, 고객의 사회적 행태를 구현하여 사용자의 흥미에 부합하는 항목들을 제안하기 때문이다. 현재까지 적절한 항목을 추천하기 위한 가장 보편적인 방법은 유사한 사용자들을 찾아 그들의 평가치를 참조하는 방법이다. 본 논문은 영화를 추천하기 위해서 장르 흥미도를 기반으로 하는 새로운 유사도 공식을 제안하는데, 이는 기존 공식에서 사용자들의 평가등급 차이를 기반으로 하는 것과 대비된다. 광범위한 실험 결과에 따르면, 제안한 공식은 정확도와 추천의 질에 있어서 전통적인 유사도 공식의 성능을 크게 향상시키는 것으로 확인되었다.
