In this paper, a method of mood classification based on user brainwaves is proposed for real-time application in commercial services. Unlike conventional mood analyzing systems, the proposed method focuses on classifying real-time user moods by analyzing the user's brainwaves. Applying brainwave-related research in commercial services requires two elements - robust performance and comfortable fit of. This paper proposes a filter based on Regularized Common Spatial Patterns (RCSP) and presents its use in the implementation of mood classification for a music service via a wireless consumer electroencephalography (EEG) device that has only 14 pins. Despite the use of fewer pins, the proposed system demonstrates approximately 10% point higher accuracy in mood classification, using the same dataset, compared to one of the best EEG-based mood-classification systems using a skullcap with 32 pins (EU FP7 PetaMedia project). This paper confirms the commercial viability of brainwave-based mood-classification technology. To analyze the improvements of the system, the changes of feature variations after applying RCSP filters and performance variations between users are also investigated. Furthermore, as a prototype service, this paper introduces a mood-based music list management system called MyMusicShuffler based on the proposed mood-classification method.

Two elements of paisley textile design (color and size of motif) were manipulated to investigate their effects on people's perception. Korean and Caucasian American women were selected to represent Asian and Western countries to compare the differences in image perceptions of paisley patterns between two cultures. The participants were 168 female university students composed of 84 Caucasian Americans and 84 Koreans. The experimental design was a $2{\times}2{\times}7$ factorial design: two levels of perceiver's culture, two levels of motif size, and seven levels of the motif color. The four factors used to account for image perception were an elegance factor, individuality factor, maturity factor, and femininity factor. The results of the present study confirm that image perception can be different according to the color and size of a motif and the perceiver's culture. In the results, Americans perceived the paisley pattern as more preferable than Koreans did. Red background + Orange motif was perceived as the most feminine and Dark blue background + Sky blue motif and Dark gray background + Gray motif was perceived as the most masculine in both cultures. Compared to the big motif, the small motif was perceived as more elegant in both cultures.

Recent increase of eco-conscious trends and pleasure from Do It Yourself (DIY) activities have led to a surge in sales of package products bundling together clothing patterns and raw materials. However, a well-structured market system is yet to be established. We surveyed 460 women with sewing as a hobby who had purchased these DIY clothing pattern packages. The survey revealed that majority of respondents had their hobby for over five years. Choosing the right fabric to match clothing patterns presented a common challenge. Most participants owned a sewing machine and an overlocker, with price being the primary concern when purchasing a package. For guidance during the sewing process, participants preferred print materials featuring real-life images. Those with less sewing experience leaned towards video tutorials. Items of interest or those commonly created included blouses, shirts, and dresses. Desire for further learning in sewing and pattern-making was prominent, with a clear preference for online classes. Several strategies are recommended to enhance the appeal of DIY clothing package products, including broadening range of packages that incorporate fabric, offering supplementary educational resources to improve users' skills, implementing affordable pricing structures, supplying comprehensive creation guidelines, and making available design modification guides. These considerations could significantly boost customer satisfaction. This research intends to lay groundwork for understanding DIY clothing creation market, ultimately fostering production of highly desirable products. Insights of this study will prove instrumental in refining product development and devising effective marketing tactics, leading to a more rewarding consumer experience.

Competition is intensifying as the golfwear market grows and expands rapidly due to the influx of MZ generation golfers, so it is necessary to plan knit golfwear products suitable to consumer needs The purpose of this study is to contribute to product planning by analyzing knit design factors according to the brand image of golfwear. First, the top five sales brands surveyed by Apparel News were selected. The selected brands were G-Fore, PXG, Malbon Golf, Titleist, and Mark & Lona. Knit products sold by the selected golfwear brands were investigated based on design factors, such as image, item, stich, yarn, color, and pattern to analyze knit design factors according to brand image. G-Fore's modern classical image was influenced by pullovers, vest items, 100% wool, color contrast, intasha stich, and monotone colors. PXG's sporty modern image was due to a mixture of rayon and polyester in jumper items, while Malbon Golf's American casual image applied character patterns and intasha knitwear. Line points, plain knitwear, and monotone colors were analyzed as design factors for Titleist's modern minimal image, while Mark & Lona's classic casual was analyzed as knit design factors, such as check patterns and jacquard knitwear. Differences in knit design factors according to brand image can be identified.

BACKGROUND/OBJECTIVES: Eating-out among Korean people has become an important part of modern lifestyle due to tremendous growth of the food service industry and various social and economic changes. This study examined trends in meal patterns and meal sources while eating-out among Korean adults aged 19 years and older. SUBJECTS/METHODS: Data were from the 1998-2012 KNHNES (Korea National Health and Nutrition Examination Survey) by the 24-hour dietary recall method. This study included 55,718 adults aged 19 years and older. For analysis of eating-out frequency, data were categorized by source of meals and serving place. RESULTS: Average frequency of meals consumed away from home increased from 1998 to 2012, although it remained lower than that of meals at home. In addition, male, unmarried, employed, higher educated, and high income individuals more frequently consumed meals away from home. Moreover, sodium intake while eating-out significantly increased from 2,370 mg in 1998 to 2,935 mg in 2012. Lastly, percentage contributions of daily total protein intake, fat intake, and sodium intake from eating-out increased to more than half (53-55%) in 2012 compared with 47-48% in 1998. CONCLUSIONS: As eating-out has grown in popularity, greater recognition of public health and nutritional education aimed at promoting healthy food choices is needed. In addition to developing consumer education for overall healthier eating patterns, individuals who are younger, unmarried, higher educated, and males are especially at risk and require attention.

It is estimated that the elderly will constitute 24.3% of the entire Korean population in 2030, when about 7,125,000 baby boomers reach retirement age. Therefore, this aging phenomenon might be the most urgent issue facing Korean society. The baby boom generation shows a strong tendency to dispose of existing residences or move into new housing after retirement, thereby exerting enormous impacts on social and economic sectors as well as the housing market. Against this backdrop, this study aims to identify both factors and patterns behind baby boomer retirees' post-retirement housing transfer trends. To this end, a survey is undertaken here with respect to those baby boomers living in Gangnam-gu and Seocho-gu with actual housing transfer plans in the foreseeable future, and who can act as a practical consumer group for the future housing market. This study verifies baby boomers' diverse preferences for housing type. Their preference for apartment houses still remains high in every situation, and this has significant implications for changed preferences of other housing types considering that most of the survey respondents currently reside in apartment houses. According to the survey, there are more than 80 kinds of baby boomers' housing transfer patterns, which demonstrates that more than half of the survey respondents pursue different housing mobility plans. When it comes to the factors behind their housing selection, the baby boom generation shows a strong preference for physical factors. However, environmental and psychological factors gain more momentum under unfavorable circumstances, while social factors play a decisive role in their housing selection in categories such as 'couple/deteriorating health' and 'single/healthy'.
