The purposes of this study were to investigate the needs for eco t-shirts of the new elderly consumers and to suggest strategies for eco t-shirts product development and marketing. Quantitative research was employed for research method. The data was collected from men and women in their age of 50-65, who lived in Busan, Ulsan, and Kyungnam province, during October, 2011. Respondents were selected by convenience sampling. A total of 307 responses among 350 were analyzed. Factor analysis, frequency analysis, t-test, chi-square, and regression were used for analysis. SPSS 20.0 was used for data analysis. Characteristics of the new elderly (lifestyle and environmental concern), consumption status of eco t-shirts (possession status and reasons of purchase/non-purchase), purchase intention for eco tshirts, consumer needs for t-shirts (usage situation, benefits sought, and dissatisfaction with t-shirts), preference for eco t-shirts (color, pattern, material, and shape), and demographics were surveyed. Based on the results, the vision of eco tshirts market for the new elderly consumers was positively prospected. In conclusion, specific strategies for eco t-shirts products development and marketing were suggested. Product development focused on practicality and material, design development reflecting consumers' preference, multipurpose product development, building up the product recognition, and moderate price strategy were suggested.

A core device of foam system is the in-line eductor and it is the device to mix the foam liquid into liquid solution proper to the use density and the mixture ratio must be kept regularly regardless of changing fluid condition of the front and rear end of the in-line eductor. However, if the flux of the pressurized water changes, the mixture ratio is not kept regularly, and so it becomes a cause which a performance of fire-extinguishing deteriorates in discharging foam liquid. I devise a method to improve it that the metering orifice type in-line eductor is improved into the metering venturi type in-line eductor, the fluctuation of the mixture ratio to the flux change of the pressurized water is minimized and the performance of fire-extinguishing is kept regularly. As this method is simple in its structure and can be designed at a low cost, it helps for maintenance as well. In the future, it seems to need the research for the metering nozzle type in-line eductor in the future.

Recently, several theories on the digital speech signal processing expanded the communication boundary between human beings and machines drastically. The aim of this study is to collect dialectal speech in Korea on a large scale and to establish a digital speech data base in order to provide the data base for further research on the Korean dialectal and the creation of value-added network. 528 informants across the country participated in this study. Acoustic characteristics of vowels and consonants are analyzed by Power spectrum and Spectrogram of CSL. Test words were made on the picture cards and letter cards which contained each vowel and each consonant in the initial position of words. Plot formants were depicted on a vowel chart and transitions of diphthongs were compared according to dialectal speech. Spectral times, VOT, VD, and TD were measured on a Spectrogram for stop consonants, and fricative frequency, intensity, and lateral formants (LF1, LF2, LF3) for fricative consonants. Nasal formants (NF1, NF2, NF3) were analyzed for different nasalities of nasal consonants. The acoustic characteristics of dialectal speech showed that young generation speakers did not show distinction between close-mid /e/ and open-mid$/\epsilon/$. The diphthongs /we/ and /wj/ showed simple vowels or diphthongs depending to dialect speech. The sibilant sound /s/ showed the aspiration preceded to fricative noise. Lateral /l/ realized variant /r/ in Kyungsang dialectal speech. The duration of nasal consonants in Chungchong dialectal speech were the longest among the dialects.

The purposes of this study are to verify the sales promotion effect of bargain sale of department store, and to investigate the relationship between the effect of bargain sale and the consumer attitude toward economics. For those purposes, secondary data was collected. The data was composed of monthly sales data of women's casual wear, men's suit, inner wear, infant's wear, and golf wear in a department store from 1996 to 2003. The data on consumer attitude toward economics was collected from 'Consumer Attitude Index' issued by SERI. The results are as follows. First, there were differences in the sales promotion effects of bargain sale by merchandise class and by year. Men's suit was the class that the effect was highest, and inner wear was the class the effect was lowest. In addition, the effects were simultaneously lowered by year. Second, sales promotion effect of bargain sale had relationship with consumer attitude index. The yearly transitions of the two data were almost similar. This means that as the consumer attitude becomes pessimistic, the motivation to consume also becomes lower, so that sales promotion effect of bargain sale also decreases. In addition, women's wear and men's suit showed the most similar transition patterns with the consumer attitude index.

This study investigates the influence of social desirability to questionnaire response and data analysis in order to identify the need for social desirability control in clothing consumer research. A questionnaire measuring social desirability, social face sensitivity, clothing shopping behavior, and demographic characteristics was developed. Responses of 234 respondents were analyzed using factor analysis, simple regression analysis, hierarchical regression analysis, descriptive analysis, and Cronbach's alpha analysis. The results were as follow. First, respondents were influenced by social desirability when they responded to items measuring other-conscious social face. Second, the result of regression analysis (that the independent variable was social formality) was less influenced by social desirability control because the influence of social desirability to social formality was insignificant. Conversely, the result of regression analysis (that the independent variable was other-conscious social face) was more influenced by social desirability control because the influence of social desirability to other-conscious social face was significant. This study is an initial study that notices the need for social desirability control in clothing consumer research.

This study is an exploratory research on the brand architecture of Korean apparel enterprises and the differentiation strategy among in-house competing brands. For data analysis, secondary data was used. 20 apparel enterprises were used as the subjects. The results are as following. First, as a result of brand architecture composition, apparel enterprises used the strategy that initially paved the way launching several brands in a specific item category and after that diversified to other categories. Most enterprises used the multi-brand strategy operating plural brands in a same zoning. The terms for launching succeeding brands were about $1{\sim}5$ years. Second, as a result of analysing the cases which several brands competes within a same zoning, all the posterior brands had some differences from the prior ones. The most frequent differentiation factor was price. Concept, target age, and distribution channel followed. The order of the factors was somewhat different among the item categories. The differentiation strategy among in-house competing brands meant that the enterprises manage plural brands in a same zoning for the growth of whole market share instead of the direct competition among in-house brands. The results of this study can suggest a growth direction to the enterprises planning to launch new brands.

This study investigates the influence of Likert scale formats such as the number of response categories and the inclusion of a mid-point from a methodological point of view using instruments that measure a fashionmarketing-related subject. Using a self-administered questionnaire, 201 respondents rated their economic clothing shopping orientation on three formats of scales that differed only in the number of response categories (ranging from 5 to 7) from February 8 to February 12, 2010. Descriptive statistics, Spearman's rank order correlation, t-test, exploratory factor analysis, confirmatory factor analysis, Pearson's correlation, and Cronbach's alpha were used in the analysis. The results are as follows. First, three scale formats were generally suitable for use due to validity and reliability. Second, the response results varied with the number of categories and the inclusion of a mid-point, although the differences were statistically insignificant (with only a few cases that differed). Third, construct validity was more secure in scales with fewer categories, whereas convergent and discriminant validity was generally good in all scale formats. Fourth, reliability coefficients were higher in scales with more categories. Fifth, the number of categories was of greater importance to instrument design than the inclusion of a mid-point. Implications for appropriate scale designs are suggested in this study.

The purpose of this study is to investigate the differences in consumer clothing shopping orientation and shopping behaviors by the multi-selection of internet and offline stores. The data were collected from 201 men and women in their twenties and the respondents were grouped into three as internet-store users, multi-store users, and offline-store users. The data were analyzed using factor analysis, ANOVA, post-hoc analysis, frequency analysis, and chi-square analysis. The results are as following. First, the clothing shopping orientation was partly different among the groups. Regarding the offline shopping orientation, the groups showed difference in the impulsive orientation, and regarding the online shopping orientation, the groups showed differences in the goal oriented and enjoying orientation. In all the three cases, the internet users showed strongest orientation, and the next were multi-store users and offline-store users. The cause of these results were explained as the familiarity and experience with the channel. Second, the clothing shopping behaviors were also partly different among the groups. The groups showed no differences in the preferred store type and benefits sought, but showed significant difference in the attitude toward the internet shopping. The internet-store users showed most positive attitude, and the next were multi-store users and offline-store users.

This study analyzes the locution of television home shopping show hosts for apparel products with a focus on the selling points and vocabulary use. A qualitative content analysis was conducted for 15 recorded home shopping shows selling women's overcoats and jackets. The results are as follows. First, 8 dimensions of selling points were revealed: Promotions, brand popularities, the experiences of shopping hosts, fashion trend information, conformity motivation and suggestion, intangible attributes, tangible attributes, and compared/leading differences. The most frequent selling point was tangible attributes. Following this were, promotions, conformity motivation and suggestion, compared/leading differences, intangible attributes, brand popularity, the experiences of the shopping hosts, and fashion trend information in order. The selling points were almost proper to decrease the perceived risks of home shopping consumers. Second, shopping hosts frequently used the clothing terms without any expatiations and used loan words (foreign language terms) instead of the direct Korean translations. In the conclusion, the development of a marketing strategy focusing on shopping host management is suggested.

From the point of view of geological history, the land of South Korea is regarded as the subject of processes of the changes in formations of several geological blocks such as Kyonggi massif, Yeongnam massif, Taebaegsan basin, Kyungsang basin and so on. Through the long period of geological chronology, the present topography and geotectonics have been formed by the complicate interactions of epirogenetic movements, magmatism, orogenesis, differential vertical movements, metamorphism and sedimentation. The reason of the crust movements mentioned above, is suppossed that the Pacific and West Pacific plate have subducted directly or indirectly into the East Asia plate. This fact can be endorsed by the results of the studies on the heat flow, gravity anomaly, absolute age dating, tectonic lineation, lithofacies and the temperature of hot spring in South Korea. The formations of metal ore deposits as well as other geological processes can be determined by the mechanical control of the plates and be divided into several systematic patterns. The investigation of about 110 metal mines in South Korea shows the following results. (1) Plate boundary volcanic type is about 28% (2) Plate boundary plutonic type is about 44% (3) Intraplate sedimentary type is about 26% (4) Intraplate magmatic type is about 2%.
