  • The ever increasing demand for enhanced competitiveness of engineered products requires "designing-in-quality" strategies that can effectively and efficiently incorporate concepts of uncertainty and quality into design. Multi-attribute utility function is commonly used to represent the decision-maker's preference on multiple design attributes under conditions of uncertainty and risk. One of the major issues in implementing this approach concerns the generation of appropriate utility function, especially in a complex engineering design environment. Typically, the decision maker's preference is revealed through lottery questions rather than being structured on the deductive reasoning to reflect the nonlinear tradeoffs among the attributes. The use of such intuitive procedures can lead to inexact preference information that may result in inaccuracy and rank reversal problems. This paper presents an alternative procedure based on the pair-wise comparisons between design alternatives towards a consistent preference presentation in assessing multiplicative utility function. The effectiveness of the overall procedures is tested with the aid of an injection-molding process design for a capacitor can and the results are discussed.

  • This study was interested in examining the image of a co-brand with the case of'CHIMERIC', the co-brand of Daegu city in Korea. The purpose of the study was to investigate the difference in brand image by brand knowledge and the effects of brand image on brand preference, brand purchase, and brand satisfaction. A total of 354 questionnaires collected from the region(Daegu)'s residents, who were aware of CHIMERIC, were analyzed. Factor analysis extracted 6 factors of brand image including symbolic image, product, ad, price, distribution, and publicity. The results revealed that there were differences in product and publicity images by brand knowledge. Symbolic and publicity images and brand knowledge affected brand preference, which in turn had the strongest effect on brand purchase. Brand knowledge also affected brand purchase while no direct effect of brand image was observed. Brand satisfaction was affected by brand preference, publicity, and ad image.

  • This paper describes a personalized advertisement technique as a part of intelligent customer services in Internet shopping malls. Based on customers' initial profile, purchase history, and behaviors in an Internet shopping mall, the technique displays appropriate advertisements on Internet web pages when customers' visit to the shopping mall. Customers preference scores for product groups which are main sources to select advertisements, are stored either a preference table or preference trees. Both of the two storage methods can support selection of advertisements on real time, and the preference tree method can reflect affinity among product groups. The suggested technique selects different advertisements to reflect changes of customers preferences as time goes by. An experiment has been performed to evaluate the effectiveness of the algorithm, which revealed that the algorithm selects more customer-oriented advertisements rather than random selection.

  • The present study explores two relationships: first, between number of payment and payment option preference, and second, total sum and payment option preference, with pain of payment as a mediator variable. The analyses revealed that consumers who feel higher pain of payment preferred the pennies-a-day pricing to the aggregate pricing when the per-payment price is low. Consumers who experience higher pain of payment prefer to pay in small frequent installments because they feel the small per-payment price can be comparable to daily expense. Consumers who experienced higher pain of payment preferred aggregate pricing to pennies-a-day pricing when the per-payment price was high. When the per-payment price is high, it is no longer comparable to daily expense, thus leading to greater pain of payment among consumers. The study discusses the implications for mechanism of pain of payment on payment option preference.

  • This study aim to identify preference of main and side dishes of 681 children who lived in Seoul and Gyoung-gi (Incheon) in 2007. To accomplish this, we divided the children into three age groups, an infancy group (below 6 years of age), a middle years group (between 7 and 12 years of age) and a juvenile group (above 12 years of age). Specifically, 145 children were in the infancy group (boys 68, girls 77), 300 children were in middle years group (boys 138, girls 162) and 236 children were in juveniles group (boys 131, girls 105). The average body mass index (BMI) of the parents of the respondents appeared to be normal, and the majority of the parents had bachelor degrees. Across all age groups, most fathers were office workers and most mothers were housewives. The preference for staple foods showed that the infancy group and the middle years group preferred rice the most, while the juvenile group preferred stir-fried rice the most out of 5 grain items. Evaluation of the preference for different types of noodles showed that both boys and girls from the infancy group preferred jajangmyun, while those in the middle years group and the juvenile group preferred spaghetti. For breads, both boys and girls from the infancy group had the highest preference for cake, while boys and girls in the middle years group and boys in the juvenile group preferred pizza the most, and girls from juvenile group preferred cake the most. Evaluation of the preference for soups and pot stew revealed that both boys and girls in the infancy group preferred seaweed soup, while boys from middle years group preferred seol-long-tang and girls from middle years group preferred seaweed soup. Boys and girls from the juvenile group preferred seol-long-tang the most. For hard-boiled foods and stir-fried foods, members of all age groups preferred beef boiled in soy sauce the most and hard-boiled peppers the least. Finally, comparison of the preference for roasted foods, seasoned vegetables and kimchi revealed that the infancy group preferred roasted seaweed the most and that both the middle years and juvenile group had the greatest preference for roasted galbi.

  • Following the previous ones, this study is intended to explore methods of qualitative assessment on the view from apartment units. It first complemented and analyzed the attributes of landscape elements and then set up questionnaire items based on these attributes to identify the tendencies in apartment inhabitants' recognition of landscape elements, and then conducted a preference assessment on the test cases sampled on the basis of picture and other data collected in the previous studies to identify the characteristics of the preference for the view from apartment units according to landscape elements. Consequently, the following results have been derived. First, the landscape elements seen from apartment units may be classified into a total of sixteen categories, and the overall ratio of natural elements to artificial ones is shown to be approximately one to three. Second, it is also shown that apartment dwellers tend to prefer natural landscape elements over artificial ones, and the preferences for the distance to and location of landscape elements exhibit certain variance depending on the type of the elements. Third, the analysis of the preference for landscape elements has revealed that the types of landscape elements, the make-up and diversity of landscape elements, and the perceived distance to landscape elements as well as the resultant feeling of openness all affect the preference tendencies.

  • The purpose of this study was to investigate the level and the reasons of son preference. and the relative importance of related variables among middle-and old-aged Koreans in Chon-buk and Chung-nam area. Subjects were 487 parents of high school girls(243 fathers and 244 mothers). with a mean age of 45.7 years. It was revealed that more than a half of the respondents(52.293) preferred'a son'for the first child, followed by'either nx'(32.6%) and'a daughter'(14.8%). For the second child, a son was preferred nlost(43.7%) , followed by'a daughter'(31.4%) and'either sex'(23.4%) . As the reasons of son preference,'to continue tradition and name of family'marked the highest score (3.42) , followed by'parents prefer son for various reasons'(3.37) , 'should have at least one son'(3.32). and'feel obliged to produce a son for in-law's sake'(3.06). It appeared that sociocultural background was more important for son Preference than individual, economic factors. The most important factors related to a strong son preference were the number of sons at the present, son preference for the first child, parental attitudes and expectations toward children. and income. Suggestions wire made in regard to efforts for gender equality in family and society. and the needs for parent education and population education.

  • The aim of this research was to empirical examine the influence of brand trust, perceived value on brand preference, and purchase intention for branded phones. The samples were gathered by a convenient sampling method. We collected data from 285 consumers who were visiting electronic supermarkets in Ho Chi Minh City, Vietnam. The measurement used a 5-point Likert scale ranging from 1=completely disagree, and 5=completely agree. PLS - Partial Least Squares method was performed to analyze the measurement model and the structural model. The study model was proposed from prior research. We had assessed the reliability of the scales through Cronbach's alpha and composite reliability. As well, we also had evaluated discriminant validity through the Fornell-Larcker criterion. The findings of the study demonstrated that brand trust had a significantly positive influence on brand preference. Likewise, the findings of the research also stated that brand trust had a positive impact on purchase intention. The results revealed that perceived value had a positive effect on brand preference. Furthermore, the outcomes show that perceived value had a positive influence on purchase intention as well. Furthermore, the findings of the research showed that brand preference had a positive effect on purchase intention.

  • Previous research for visual assessment of streetscape employed static simulation methods to represent future landscape. However, streetscape is experienced sequentially, and thus dynamic simulations can be more effective. This study tried to adopt computer animation in the evaluation of streetscape, and examined its effects and possibilities. Three development scenarios for the redevelopment districts of Sokong-Ro and Banpo-Ro in Seoul were designed, and simulations were produced by three methods-photo-retouching, computer still image, and animation. A preference questionnaire was asked to 69 university students, and the effects of simulation methods on visual preference were examined. In addition, the frames of the animation were reclassed to identify the visibility of physical elements. The relationships between the visibility and visual preference were analyzed. The results showed that visual preference can be explained by three factors-Amenity, Tidiness, and Variousness-that account for 62.4% of the total variance, and the Amenity showed the highest proportion: 36.0%. Among the three simulation methods, animation showed the largest difference in preference for the most important factor(Amenity), and yielded the highest correlation between visibility of physical elements and Amenity. This result demonstrated that dynamic simulations can provide more accurate observation of visual changes, especially because the simulated landscape is experienced sequentially. The results also revealed that the sequential change in the visibility of physical elements can be examined easily and precisely by animation. This benefit of animation enables analysts to identify the points where the landscape varies the most, and thus visual preference should be evaluated.

  • The current study examined the influence of individual trait such as Need-For-Touch level (NFT; high vs. low) and swiping orientation (vertical vs. horizontal) on product evaluation and preference when using touch-screen interface like a smart phone and a tablet. Swiping is one of the most common interaction techniques for changing pages or searching some aligned pictures on touch-screen interface and it can be used in vertical and horizontal orientations. The experiment revealed a significant interaction between swiping orientation and NFT on preference, however the interaction on change-in-price of given products was only marginally significant. To be specific, high NFT participants reported higher preference for horizontal-swipe than vertical-swipe products, but such difference did not occur with low NFT participants. The current study illustrates the influence of swiping orientation and NFT on product preference and it provides a new perspective of design principles especially for online shopping websites.
