In this study, nine scarf designs expected to be effective for accent design for the fashion style of new senior women were suggested by reflecting purchase behavior and scarf preference after conducting surveys and an analysis by targeting 136 new senior women in order to propose scarf design-matching with the preferences of new seniors. As a result of the study on the scarf purchase features of new seniors, it was revealed that the purchase time for scarves was mainly autumn and winter, even though it is regardless of season, and in spring and summer, they seldom purchased scarves. The purchase frequency was four times a year, and what they first thought of at the time of purchase was represented in the order of color, design, and the material of the scarf. They most preferred department stores, mixed and achromatic colors, cotton and silk fabrics, natural and geometric patterns, and long scarves of a rectangular shape. In the case of the consumer attributes of scarves, it was revealed that $50^{th}$ desired more individuality-oriented, unique scarf designs than $60^{th}$, and $60^{th}$ desired scarf designs with convenient management considering others' attention compared with $50^{th}$. As concepts for scarf designs, the aspects of individuality, co-existence, and maturity were extracted by reflecting the features of new senior women, and a total of nine scarf designs were suggested by developing three sub-designs for each concept.

This study investigates the causal relationships among the factors influencing behavioral intention related to beef traceability and TAM to make diet safer. To do this, this study conducted a survey targeting the customers who use the department stores, specialty shops and large supermarkets in Seoul. The result is as follows. First, the higher the information quality in beef traceability(t=3.872) and social impact (t=1.938) were, the higher the usability became significantly. Second, as the social impact of food traceability(t=2.014), information accessibility(t=2.016), perceived risk(t=1.910) became higher, the perceived usefulness was shown significantly higher. Third, as the usability(t=5.826) was perceived higher, the perceived usefulness became higher. Fourth, the higher the perceived usefulness(t=4.264), the higher the behavioral intention among the customers. Also, the lower the usability(t=-0.682), the lower the behavioral intention.

In this paper, monaural ambient component extraction algorithm based on nonnegative matrix factorization (NMF) is described. The ambience component extraction algorithm in this paper is developed for audio upmixing system; Recent researches have shown that they can enhance listener envelopment if the extracted ambient signal is applied into the multichannel audio upmixing system. However, the conventional method stores all of the audio signal and processes all at once, so it cannot be applied to streaming system and digital signal processor (DSP) system. In this paper, the ambient component extraction algorithm based on on-line nonnegative matrix factorization is developed and evaluated to solve the problem. As a result of analysis of the processed signal with spectral flatness measures in the experiment, it was shown that the developed system can extract the ambient signal similarly with the conventional batch process system.

G-code, another name of ISO6983, has been a popular commanding language for operating machine tools. This G-code, however, limits the usage of today's fast evolving high-performance hardware. For intelligent machines, the communications between machine and CAD/CAM departments become important, but the loss of information during generating G-code makes the production department isolated. The new standard for operating machine tools, named STEP-NC is just about to be standardized as ISO14649. As this new standard stores CAD/CAM information as well as operation commands of CNC machines, and this characteristic makes this machine able to exchange information with other departments. In this research, the new CNC machine operated by STEP-NC was built and tested. Unlike other prototypes of STEP-NC milling machines, this system uses the STEP-NC file in XML file form as data input. This machine loads information from XML file and deals with XML file structure. It is possible for this machine to exchange information to other databases using XML. The STEP-NC milling machines in this research loads information from the XML file, makes tool paths for two5D features with information of STEP-NC, and machines automatically without making G-code. All software is programmed with Visual $C^{++}$, and the milling machine is built with table milling machine, step motors, and motion control board for PC that can be directly controlled by Visual $C^{++}$ commands. All software and hardware modules are independent from each other; it allows convenient substitution and expansion of the milling machine. Example 1 in ISO14649-11 having the full geometry and machining information and example 2 having only the geometry and tool information were used to test the automatic machining capability of this system.

The purpose of this study were to identify the difference of demographic variables, motivation and dissatisfaction to purchase of groups who classified by frequency of purchase. Data were collected via intercept surveys conducted at nine regional branches of two major department stores situated in Seoul. Participants(n=1,120), who had previously purchased women's private brand apparel, were asked to complete a questionnaire. The results of this study were as follows; The subjects were classified into 3 groups by frequency of purchase and their demographic variables were analyzed. The customer groups of high frequency who were 18 to 39 years old had some college education, housewives and white collar workers. Their monthly household income is one to three million won and their monthly expenditure is 100,000 to 300,000 won on apparel shopping. The most important purchase motivation of lower frequency groups was design, whereas that of middle and high frequency groups was good quality over price.

This study, Based on the study theories of up to the present was to a consumer's shopping motive, the process of choice and the theory of a consumer's store choice by his or her preference. It investigates the components of store image referring many thesis from documents of domestic and foreign countries. The major findings of from study an as follows: First, as general characteristics of samples, the component ratio of women is much higher than that of men. As for marital status, married consumers are large in numbers, and for educational back ground, high educated young couples go shopping frequently at department stores. As for ages, consumers under the 30s take great part in, for the occupation, many are housewives and for the average income of a month, under one million won income earners are major consumers. Second, about shopping motive, married ones do it for refreshing themselves, but for singles, they do shopping for the pleasure of bargain sales. The most important reason which influences on the shopping motive is 'pleasure of bargain sales' regardless of all ages. Third, according to the analysis of shopping motive and the characteristics of 15 store images, there are noteworthy differences statistically in shopping motive, attraction and reliance on advertisement, an atmosphere of a store and the degree of crowdedness.

The purpose of this study was to find out effects of treatment of ginsenoside Re, Rc and EGCG on mRNA expressions of leptin, hormone sensitive lipase (HSL) and resistin in 3T3-L1 adipocytes. The concentrations of EGCG were treated with $0.01{\times}10^{-7},\;0.1{\times}10^{-7},\;1{\times}10^{-7}\;and\;1{\times}10^{-6}\;or\;100{\mu}g/ml$ ginsenoside Re, Rc in culture cell for 13 days. mRNA expression of leptin wasn't expressed in preadipocyte but according to differentiation of adipocyte, the that of mRNA expression was decreased at gensenosids or EGCG treated cells compared with non treated adipocyte. Expression of HSL mRNA was increased in G-Re, G-Rc and EGCG treated cells compared with non treated cells. The resistin level was significantly decreased in adipocytes treated with G-Re, G-Rc and EGCG. These pattern was similar to leptin expression. These results support that treatment of gensenosides or EGCG in 3T3-L1 adipocyte resulted to affect of leptin and resistin as well as HSL mRNA levels, accordingly, levels of leptin and HSL will be acted by signalling body fat stores to the hypothalamus which in turn regulates food intake andenergy expenditure to maintain body weight homeostasis. And also regulation of resistin mRNA will prevent to diabetics attacked with obesity. In conclusion, we suggest that consumption of ginseng saponine or EGCG might prevent human diabetics or/and obesity.

The present study was undertaken to investigate the physiological characteristics of the adrenergic responses in the tilapia dorsal aorta. Epinephrine, norepinephrine, clonidine and methoxamine in the presence of propranolol($3{\times}10^{-6}$M), induced only endothelium-independent and concentration-dependent vasocontractions in tilapia dorsal aorta. The rank order of potency of adrenergic agonists inducing vasocontraction was epinephrine>norepinephrine>phenylephrine>clonidine>ethoxamine, Yohimbine produced a parallel shift of the concentration-vascontraction curves of epinephrine, norepinephrine, phenylephrine and clonidine to the right, while prazosin depressed the maximum responses of epinephrine and norepinephrine. Calcium-free physiological solution and verapamil markedly reduced epinephrine or norepinephrine-induced vasocontractions. These results suggest that a-adrenergic agonists produce only on endothelium-inedpenent casoconstrictions in tilapia dorsal aorta and these effect of a-adrenergic agonists, which might be associated with both calcium release from intracellular stores and calcium influx through voltage-dependent calcium channel.

This paper presents calorie expenditure prediction model of daily activity of elderly living alone for LBS(Location Based Service) applications. The proposed method is to describe the daily activity patterns of older adult using PIR (Passive InfraRed) motion sensors and to examine the relationships between physical activity and calorie expenditure. The developed motion detecting system is composed of a sensing system and a server system. The motion detecting system is a set of wireless sensor nodes which has PIR sensor to detect a motion of elder. Each sensing node sends its detection signal to a home gateway via wireless link. The home gateway stores the received signals into a remote database. The server system is composed of a database server and a web server, which provides web-based monitoring system to caregivers for more effective services. The experiment results show the adaptability and feasibility of the calorie expenditure model.

The purpose of this study was to research buying behavior and home fashion preferences based on housing size. The target consumers were Korean women, aged 20~40s who reside in the Seoul & Kyunggido areas. We distributed questionnaires to 650 women. However, only 600 questionnaires were used for the statistical analysis. Data analyses were conducted with SPSS program on the frequency, Chi-square test, cluster analysis, t-test and ANOVA. The results of this study are as follows: 1. The considering factors for purchasing such as brand, trends coordinating existing furnishings with new products and functionality were significantly associated with housing size. The buyers who reside in bigger size homes. over 40 pyung place higher value on brand name, trends. or coordinating existing furnishing with new products than residents in smaller units. However, women who live in smaller units place higher value on functionality when purchasing home fashion products. Considering factors such as brand, trend, and materials were also significantly associated with segmented age group; 40~49 age group considered brand, trend, and materials more than 20~29 age group. The group who are highly interested in home fashion considered design/color, rand, coordination, and functionality than the group who are low interested in home fashion. 2. Residents in over 40 pyung homes buy home fashion products at department stores, while residents in less than 39 pyung homes buy them at discounted store. 3. Respondents preferred solid colors more than patterns. However, they favored character pattern for textile bedding products for their children. 4. there is also a statistical difference in preferences for types of window treatments between large ad small housing sizes. Residents living in over 40 pyung preferred tie-back/cottage curtain, while residents living in less than 29 pyung preferred Roman shade style.
