The purpose of this stud is : (1) to figure out the amount of time being usually spent on the housework performed by the employed wives and (2) to find out factors influencing the total and the specified housework time. The major findings are the following : 1) A employed wife spends 374 minutes(6.2 hours) on the average a day on the housework. Compared with research results of the past, this shows little difference, and less 157 minutes than full time homeworker. Time connected with meals is 123minutes, clothing (68), management and marketing(64), family care(61), and housing care(58). 2) Family environment variables (the wife's education level, wife's employment status, income, young child's age and presence of employed housekeeper) significantly differentiates the housework time. In general, a wife with higher SES level spends less time for housework except family care. 3) Housework related variables (planning, preference, performance competency, and performance stand rd) significantly differentiate the specified houseworks. High planning, preference, and performance competency do not necessarily diminish the housework time except routine houseworks. High performance standard causes her to spend more time. 4) A wife' sex-role attitudes and a husbands attitudes perceived are more traditional, she spends more time.

The purpose of this study was to reveal the influence of consumers' Hanbok involvement and arousal seeking tendency on their Hanbok preference and purchasing behavior. The survey subjects were male and female consumers ranging in age from teens to those in their fifties. An online survey was conducted, and 627 people were analyzed. Version 26.0 of SPSS was used to perform a t-test as well as frequency, correlation, factor, reliability, and regression analyses. As a result, both Hanbok involvement and arousal seeking tendency derived four factors each. All four factors of Hanbok involvement had a significant effect on Hanbok preference. Two factors of arousal seeking tendency had a significant effect on Hanbok preference. Hanbok preference had a partially significant effect on Hanbok purchasing behavior. Hanbok involvement and arousal seeking tendency had a partially significant impact on Hanbok purchasing behavior. In conclusion, this study is meaningful in that it, for the first time, derived the factor of Hanbok involvement by considering the concept of involvement as it relates to Hanbok and identified that involvement and arousal seeking tendency are variables that affect Hanbok preference and purchasing behavior.

Based on increased popularity and use of social network services as a marketing tool, social commerce became an emerging trend in e-commerce platforms. Social commerce involves sellers offering potential consumers the products and services at a lower price in a limited time period. Through comparison of the performances of domestic social commerce websites, we found that the buying environment such as price, number of available products, and the remaining time period for sale has a significant difference influencing on the purchase decisions of consumers. This study aims to analyze the interaction effects and preference levels of four characteristics (price, discount rate, number of purchases and purchase time) by conducting choice-based conjoint analysis. Survey experiment was performed using a sample of 146 undergraduate and graduate students. The results showed that consumers importantly consider purchase time, discount rate, price, number of purchases in the order of their preference. Also, discount effect is more significant on purchase decisions than price effect and consumers distinguish less the differences among the buying environment characteristics in the closing days of purchase period. Customer segmentation using the preference levels of characteristics indicates that the preference levels have different effects in the purchase utility of each segment. The proposed customer segmentation and differences in feature utilities are expected to be valuable in forming future sales promotion strategies in social commerce.

As recent fusion industry and ubiquitous technology have grown fast, network contents, which require high load, are provided in various infrastructures and facilities such as u-city and smart phones. Therefore, it is anticipated that the playback quality of multimedia compared to network loads degrades dramatically due to the drastic increment of real-time reference of conventional high load contents (eg. multimedia data). In this paper, we improved the method of the traffic assignment based on MPP which elevated the playback quality of multimedia by assigning discriminately the possible traffic of MMS with TP coefficients. When the TP coefficient which combines content preference with media preference was applied to a real-time traffic assignment scheduler, the simulation results showed that the multimedia playback stream was assigned within the possible traffic of a server. The real-time scheduling algorithm was improved by using the TP coefficient that combines the time-dependent image contents and the weighted value of media preference. It was observed from the experiment that the loss of the possible traffic decreases to 3.91% and 3.88% for three and four clients respectively.

In this study, the entrapped number is investigated on the UV light with different illuminance to fluorescent bait cage for swimming crab in order to find the appropriate illuminance which has the best attraction effect of fluorescent bait cage for pots. In addition, preference to the light, arrival time and residence time at light area are compared and analyzed to fluorescent bait cage and non-fluorescent bait cage for American lobster at the UV light and ordinary light according to the illuminance condition. Pot with red non-fluorescent bait cage at the no lighting (<0.01lux), pot with blue fluorescent bait cage at the 20W UV lighting (0.16lux) and pot with blue fluorescent bait cage at the 30W UV lighting (0.22lux) were soaked for 6 hours and the entrapped number of swimming crab was examined. The mean entrapped number of swimming crab in pot with red non-fluorescent bait cage at the no lighting (<0.01lux) was 1.0, but the mean entrapped number of swimming crab in pot with blue fluorescent bait cages at the 20W UV lighting (0.16lux) and 30W UV lighting (0.22lux) were 1.4 and 0.4, respectively (P<0.05). The rate of preference to the blue fluorescent bait cage at the UV lighting shows 1.6-4.8 times higher than that of preference to the red non-fluorescent bait cage at the ordinary lighting. In addition, The rate of preference to the blue fluorescent bait cage at the UV lighting is higher when the illuminance of ordinary light is same as or is lower than that of UV light (P<0.05). However, the preference to the light depending on gender shows no significant difference (P>0.05). The arrival time to UV light area of lobster is shown as 1.2-2.4 times faster than that to ordinary light area. Generally, it is shown that arrival time to UV light area is faster than the arrival time to ordinary light area when the illuminance of ordinary light is the same as or lower than that of UV light (P<0.05). However, arrival time to the light area depending on gender shows no significant difference (P>0.05). The residence time at UV light area of lobster is 1.2-1.7 times longer than that at ordinary light area. The residence time depending on different illuminance of ordinary light and genders showed no significant difference (P>0.05).

Warning control is one of the most important components in driver's cabin for achieving safe driving. The purpose of this study is to suggest ergonomically optimal location and type of passenger car's warning control. An experiment was conducted using driving simulator, in which nine locations and two types of warning controls -push button, rocker switch- were employed as experimental variables, and response time for warning signal and preference for locations and types of warning controls were measured as dependent variables. The results showed that response time for warning signal was the shortest when warning control was located at the middle left corner of the center fascia, and was the second at the middle center of the center fascia. Preference for warning signal was the highest at the middle left comer of the center fascia, and was the second between the steering wheel column and the center fascia. Although push button was not preferred to rocker switch, response time was shorter for push button than for rocker switch. It was suggested from these results that warning control with the type of push button should he located at among the middle left corner of the center fascia, the middle center of the center fascia, and between the steering wheel column and the center fascia.

Color is one of the most effective factor in visual aspect influencing consumer's choice. However, the color preference varies as time passes, society changes, new culture develops, that is variable in its nature. And the underlying meaning or accompanying color image differs in every area. We believe the study on the color preference is meaningful, especially on BRICs market, recently gathering attentions for their market competitiveness and growth potential. For this research, data collected from 5 countries(including Korea) by 1:1 interview during 3 weeks in Aug. 2005. Usable data from 923 adult urban residents were used for final data analysis. Color chart for research was categorized by using COS Color System into KS standard color 10grades plus 1 neutral, with 5 grades of tones. Through this empirical study, the data were analyzed by mean, ANOVA, Duncan-test of SPSS Win(ver.10.0). The result generated from this study are as follows : First, analysis through hue & tone system reveals that preference on principle colors (R, Y, G, B, P) is higher than intermediate colors and pale, light, vivid tones were preferred to dare and deep tones. Second, personal color preference is reflected in color preference in fashion items. Thus, we may conclude color preference in fashion item largely influenced by country characteristics. Third, biggest difference by country from hue analysis are neutral and PB colors. Neutral, widely preferred color in every county, more preferred in India, Russia, Brazil than China. We expect this result can be utilized as a basic material for developing BRICs market.
