The purpose of this research was to examine the subjective evaluation of sensory images and preferences according to the mechanical properties of linen and ramie fabrics for summer shirts. 54 male and female teachers evaluated the sensory images and preferences of 6 specimens of linen and ramie fabrics sold on the market. For statistical analysis, factor analysis, Mann-Whitney and Kruskal-Wallis test, Pearson correlation, and regression were used. The results were as follows: The sensory images of shirt fabrics were classified into 5 factors: 'smoothness', 'stiffness', 'elasticity', 'dry/coolness', and 'wetness'. There were partially significant differences by the gender and age in the sensory images for the shirt fabrics. Females were more sensitive than males for the 'stiffness', 'elasticity', and 'wetness' factor and the evaluators in their 20's felt fabrics were stiffer. The sensory images showed many correlations with the mechanical properties of fabric mostly. The preferences of tactile and purchase were no different according to the gender and age. They preferred a thin and soft sensory image as like ramie/cotton blended fabric and bamboo fabric for summer shirts. The significant sensory image factors affecting tactile preference were 'smoothness', 'dry/coolness', and 'elasticity', and the ones affecting purchase preference were 'smoothness', 'stiffness', 'dry/coolness', and 'elasticity'. W, WT, MMD, and G properties of the mechanical properties of fabrics affected the tactile preference for summer shirt fabrics.

This study examined college students' propensity for materialism and conspicuous consumption, and their preference for imported-luxury brand products. This study also identified the factors that influence college students preference for the imported-luxury brands. The data were obtained from a questionnaire completed by 4-year-college students (N=309), and were analyzed by t-tests, ANOVA, and multiple regression analyses. The findings of this study are as follows: First, college students' propensities for both materialism and conspicuous consumption were a little higher than the middle points of the scales. Their preference for imported-luxury brands was a little below the middle point of the scale. Second, the propensity for materialism was higher among first- and second-year students than among third- and fourth-year students. The occupation of household head was significantly related with the levels of materialism and conspicuous consumption, as well as the preference for imported-luxury brand products. Female students were more likely to prefer imported-luxury brands. Those with a higher income and subjective level of living were more likely to have the propensity for conspicuous consumption and preferences for imported-luxury brands. Third, the imported-luxury brands preferences were positively associated with the propensities for both materialism and conspicuous consumption.

This study analyzed the pressure, subjective wearing comfort, and design preference of brassiere shoulder straps among women in their 20s and 40s. Experimental clothing was made by different shoulder strap designs on a brassiere. In the four designs (A-D), the front attachment points of the shoulder straps were the same, but the back attachment points were different. Three of them (E, E1, E2) were of a halter neck design, with different front attachment positions. The pressures of A-D were measured at the position passing through the shoulder line (P1), and E-E2 was measured at the back neck (P2) as well as at P1. Subjective wearing comfort and design preference were rated on a 7-point Likert scale. A was determined to exert the highest pressure at the neck side of the design in the pressure measurement analysis of A-E2, whereas E1 exerted the lowest. E was measured to have the highest pressure among the E-E2 designs, whereas E2 had the lowest. Participants preferred A the most and E the least in regards to the subjective wearing comfort of A-E. Thus, participants deem A to be the most comfortable despite the high strap pressure. However, E was the most favored design, despite its poor wearing comfort. Participants' subjective impressions of E-E2 were that E2 was the most uncomfortable, but its design was the most preferred. Consumers' design preferences and subjective impressions of wearing comfort did not match.

Component-based software reuse has been generally regarded as a promising approach to improving software productivity and quality within software development. However, progress in component-based software reuse has been slower than expected. Much of the software reuse literature points to the lack of software components that can maximize users' benefits as the most important source of the slow progress. Considering that the underlying processes behind component-based software reuse are strikingly similar to commercial software marketing, this paper attempts to identify the aspects of software components that consumers value and to establish relationships between the identified aspects and consumer behavior in the software component market. More specifically, this paper focuses on the perceived subjective features of software components. This study was conducted in a web-based artificial market environment called "SofTrade."

BACKGROUND/OBJECTIVES: Excessive sugar intake is one of the causes associated with obesity and several chronic diseases prevalent in the modern society. This study was undertaken to investigate the effect of parenting variables based on the theory of planned behavior, on the sweetness preferences and sweets intake of children. SUBJECTS/METHODS: Parents and their children (n = 103, aged 5-7 years) were enrolled to participate in a survey for this study, after providing the required informed consent. Parents were asked to fill out a self-administered questionnaire at their residence. The sweetness preference test for children was conducted at a kindergarten (or daycare center) by applying the one-on-one interview method. RESULTS: The children were divided into two clusters categorized by the K-mean cluster analysis: Cluster 1 had higher sweetness preference (0.42 M sugar, 35%; 0.61 M sugar, 65%); Cluster 2 exhibited lower sweetness preference (0.14 M sugar, 9.5%; 0.20 M sugar, 9.5%; 0.29 M sugar, 81%). Cluster 1 had a higher frequency of sweets intake (P < 0.01), and lower sweets restriction (P < 0.05) and nutrition quotient score (P < 0.05). Sweets intake was negatively correlated with the nutritional quotient (r = -0.204, P < 0.05). The behavioral intention of parents was higher in cluster 2 (P < 0.05), while affective attitude, feeding practice, and reward were higher in cluster 1 (P < 0.001, P < 0.05, and P < 0.01, respectively). Furthermore, behavioral intention of parents showed a negative correlation with affective attitude (r = -0.282, P < 0.01) and feeding practice (r = -0.380, P < 0.01), and a positive correlation with subjective norm (r = 0.203, P < 0.05) and parenting attitude (r = 0.433, P < 0.01). CONCLUSIONS: This study indicates that the sweetness preferences and sweets intake of children is related to the parent's affective attitude, feeding practice and reward. We suggest that to reduce the sugar consumption of children, guidelines for access to sweets and pertinent parenting practices are required.

본 연구는 애니메이션 수용자의 인식유형과 취향에 관한 주관성연구이다. 이에 본 연구의 방법론으로써 Q방법론(Q-methodology)을 사용하였다. Q방법론은 인간의 태도와 행동을 연구하기 위해 철학적, 심리학적, 통계적 그리고 심리측정과 관련된 개념을 통합한 방법론으로서 인간의 주관성을 정량적으로 분석할 수 있는 특수한 통계기법이다. 기존의 양적방법론인 R방법론이 차이의 심리학(differential psychology)에 기본 가정을 두고 수용자 간의 차이를 수용자가 특정한 변인에 대해 얻은 개별적 특성의 차를 반영하는 것이라면, Q방법론은 의미성에 있어서 수용자 개인의 내적 차이 즉, 주관성의 개별 특성을 근거로 한다. 따라서 매체, 혹은 영상 장르에 대한 수용자의 주관적 인식특성을 연구함에 있어 Q방법론은 매우 유용하게 활용될 수 있다. 이러한 Q방법론을 사용한 결과 애니메이션 장르에 대해 수용자들의 다양한 선호유형별 특징을 발견할 수 있었다. 각 유형별 특징은 먼저 스토리텔링과 서사적 가치를 추구하는 문학, 서사적 가치 지향형, 캐릭터와 미장센 등과 같은 영상미를 추구하는 회화, 심미적 가치 추구형, 그리고 마지막으로 오락적 요소와 볼거리를 선호하는 대중 오락적 가치 지향형 등 3개의 유형으로 분류되었다. 이와 같은 선호 유형의 구분을 통해 추론할 수 있었던 것은 영상의 생산과 소비가 가능한 능동적 취향의 디지털영상세대 수용자들은 계급위치의 상징적 표현으로써 자신들의 취향문화를 구분하고 받아들이기 보다는, 철저히 개인적 혹은 주관적 성향에 따라 주체적으로 기호를 소비하는 듯한 경향을 보이고 있다는 것이었다. 이러한 면에서 수용자의 주관성을 분석하는 데에 유용한 Q 방법론적 고찰은 의미 있는 작업이 될 수 있었다. 하지만 그럼에도 불구하고 본 연구만으로는 구체적 취향의 다양한 생성 맥락까지는 밝혀낼 수 없었다. 이에 본 연구와 함께 다양한 질적 혹은 양적 방법론을 함께 적용하여 수용자의 인식유형 및 선호도를 분석해 본다면 좀 더 유의미한 결과를 얻어낼 수 있을 것이라 생각된다.

The purpose of this study is to examine the hand of spring/fall fabrics for 'Saenghwal Hanbok' on subjective hand, objective hand and the preference. In this study, 28 varieties of spring/fall fabrics such as cotton fabrics, synthetic fabrics, blended fabrics and a silk fabric for 'Saenghwal Hanbok' are used. To evaluate the subjective hand of fabrics, the holistic touch and preferences, 33 seven ranks' segmentic differential scale questions are developed with adjective pairs and are gathered by surveying experts on clothes. The mechanical properties, HV and THV of them are measured and calculated by KES-FB system. Through subjective hand, items could be classified into six hand expressions: 'bulky/extensibility', 'stiffness', 'feeling of weight', 'surface property', 'drapability' and 'moisture property'. Through mechanical properties, the results indicated that the character of cotton fabrics are slight flexible, tough, rough, uneven, a bit heavy, thick and low resilience on tensile and compression, and then those of synthetic fabrics, blended fabrics and a silk fabric are thin and light, smooth, flat and bulkless. In correlation on subjective evaluations and the preference for 'Saenghwal Hanbok', cotton fabrics mainly depend on 'surface property' and 'moisture property' and then synthetic fabrics, blended fabrics and a silk depend on 'bulky/extensibility' and 'surface property' In correlation on objective hand and the preference for 'Saenghwal Hanbok'. people aren't satisfied with low resilience. high stiffness and low drape.

The elderly population is rapidly increasing worldwide, but many face challenges in using digital tools like the Internet due to health and incapacity issues. Existing online search user interfaces (UIs) often overlook the specific usability needs of the elderly. This study proposes an adaptable web search UI model for the elderly, based on their perspectives, to enhance search performance and usability. The proposed UI model is evaluated through comparative usability testing with 20 participants, comparing it to the Google search UI. Effectiveness, efficiency, and satisfaction are measured using task completion time, error rate, and subjective preferences. The results show significant differences (p > 0.05) between the proposed web search UI model and the Google search UI. The proposed UI model achieves higher subjective satisfaction levels, indicating better alignment with the needs and preferences of elderly users. It also reduces task completion time, indicating improved efficiency, and decreases the error rate, suggesting enhanced effectiveness. These findings emphasize the importance of considering the unique usability needs of the elderly when designing search UIs. The proposed adaptable web search UI model offers a promising approach to enhance the digital experiences of elderly users. This study lays the groundwork for further development and refinement of adaptable web search UI models that cater to the specific needs of elderly users, enabling designers to create more inclusive and user-friendly search interfaces for the growing elderly population.
