The purposes of this study were to investigate the differences in clothing consumption behaviors among female consumer groups in their twenties and to understand the type of consumer group pursuing fast fashion. Questionnaire survey was conducted to 230 female consumers residing in Seoul and Kyung Gi area from June 18 to 29 in 2007, and 178 were used for data analysis. Data analysis were conducted with SPSS 12 program on the reliability test, factor analysis, cluster analysis, correlation analysis, ANOVA, Duncan's multiple range test. Factors analyses were employed for the attitude toward fashion and shopping, and shopping motives. Four factors were formulated for the attitude toward fashion: interest in fashion, fashion-orientation, fashion leadership and fashion conformity. Six factors for the attitude toward shopping were found: information searching, shopping enjoyment, store patronage, impulse buying, brand-orientation and convenience. Buying motives for fashion goods were classified into 3 factors: for matching & occasion, to-be-in-fashion and for necessity. Four clusters were identified based on the attitude toward fashion: the fashion-interested, the fashion-indifferent, fashion leaders and the individuality-oriented. Among the groups, significant differences were found in information searching, shopping enjoyment and store patronage. Fashion leaders tended to spend more for expensive and up-to-dated fashion items, and for higher quantity than other groups. Consequently fashion leaders showed attractive customer characteristics for the fast fashion companies.

The present study aims to provide an analytical framework for achieving aid and development effectiveness of agricultural cooperation with a demand-oriented perspective. This paper pays particular attention to categorize the stages of agricultural development of African recipients to identify demands for agricultural aid of the categorized groups. To do so, first of all, it establishes theoretical background to apply the demand-oriented concept and utilize the phase of agricultural development as an alternative for aid and development effectiveness. On the basis of the theoretical robustness, it conducts a series of analyses to categorize the African recipients by the development stages, incorporating factor analysis, cluster analysis and comparison between the present-future agricultural development levels. The findings propose analysis indicators for phase of agricultural development and clustered results including 18 countries of KAFACI members and priority countries in Africa. In addition to the practical application of the results, the methodological flow can be used as steps for sketching a future roadmap to construct the demand-oriented ODA(Official Development Assistance) plan. This paper also offers implications regarding ODA strategy of Korea in response to the phase of agricultural development and the aid demands.

Taste sensitivity to sugars plays an essential role in the initiation of feeding behavior. In Drosophila melanogaster, recent studies have identified several gustatory receptor (Gr) genes required for sensing sweet compounds. However, it is as yet undetermined how these GRs function as taste receptors tuned to a wide range of sugars. Among sugars, fructose has been suggested to be detected by a distinct receptor from other sugars. While GR43A has been reported to sense fructose in the brain, it is not expressed in labellar gustatory receptor neurons that show taste response to fructose. In contrast, the Gr64a-Gr64f gene cluster was recently shown to be associated with fructose sensitivity. Here we sought to decipher the genes required for fructose response among Gr64a-Gr64f genes. Unexpectedly, the qPCR analyses for these genes show that labellar expression levels of Gr64d and Gr64e are higher in fructose low-sensitivity flies than in high-sensitivity flies. Moreover, gustatory nerve responses to fructose in labellar sensilla are higher in Gr64d and Gr64f mutant lines than in mutant flies of the other Gr64a-Gr64f genes. These data suggest the possibility that deletion of GR64D or GR64F may indirectly induce enhanced fructose sensitivity in the labellum. Finally, we conclude that response to fructose cannot be explained by a single one of the Gr64a-Gr64f genes.

A high-performance liquid chromatography-electrospray ionization-tandem mass spectrometric method was developed to determine simultaneously eight marker constituents of Forsythiae fructus, and subsequently applied it to classify its two botanical origins. The marker compounds of Forsythia suspensa were phillyrin, pinoresinol, phillygenin, lariciresinol and forsythiaside; those of F.viridissima were arctiin, arctigenin and matairesinol. Separation of the eight analytes was achieved on a phenyl-hexyl column (150${\times}$2.0 mm i.d., 3 ${\mu}M$) using gradient elution with the mobile phase: (A) 10% acetonitrile in 0.5% acetic acid, (B) 40% aqueous acetonitrile. A few fragment ions specific to the types of lignans, among the product ions generated by collisonally induced dissociation (CID) of molecular ion clusters, such as [M-H]$^-$ or [M+OAc]$^-$ were used not only for fingerprinting analysis but for the quantification of each epimer by using multiple-reaction monitoring mode. It was shown good linearity ($r^2{\geq}$ 0.9998) over the wide range of all analytes; intra- and inter-day precisions (RSD, %) were within 9.14% and the accuracy ranged from 84.3 to 115.1%. The analytical results of 40 drug samples, combined with multivariate statistical analyses - principal component analysis (PCA) and hierarchical cluster analysis (HCA) - clearly demonstrated the classification of the test samples according to their botanical origins. This method would provide a practical strategy for assessing the authenticity or quality of the herbal drug.

The purposes of this study were to investigate demographic profiles between the consumer group under high time pressure(HTP) and the group under low time pressure(LTP) during the shopping, to examine the level of association between the fashion information sources and time pressure variable, to determine the difference in clothing benefits sought between HTP and LTP, and to determine the difference in purchase criteria. We distributed questionnaires to 600 women aged in 20-65. The reliable 562 questionnaires were used for a statistical analysis. Data analyses were conducted with SPSS program on t-test, cluster analysis, factor analysis, and Chi square test. We obtained the following results: There was a significant association between demographic variables such as age, occupation, education, residence area, & family cycle and time pressure variable. Fashion information sources were classified into 4 factors. HTP searched information on fashion products using more various sources than LTP did. There was also a significant difference between HTP and LTP in clothing benefit sought. Four clothing benefit factors such as trendy/social position, economic value, protection/comfort, and makeup of body shape were sought more by HTP than by LTP. In addition, HTP considered significantly more purchase criteria such as color/pattern, comfort, quality, suitability, material, sewing finishing, coordination, price, brand, easy care, and country of origin than LTP.

The purpose of this study was to identify factors of shopping orientation and factors of preferred stores for female shoppers aged from 45 to 64. Also women's markets for these ages were segmented based on their shopping orientation, and consumer groups were compared in terms of demographics and preferred store characteristics. Data from 238 women aged between 45-64 were collected by survey method and used for statistical analyses. Factor analysis, cluster analysis, $X^2$ test, F test, Duncan test were done. The results were as follows. First, five shopping orientation factors, such as high involvement, fashion orientation, brand orientation, other people orientation, and economic orientation were found. Second, five factors of preferred store characteristics were identified. They were store environment, product characteristics, trend and brand, accessibility, and sales personnel factors. Four consumer groups of brand pursuing, fashion pursuing, other-dependent, and high-involvement were classified. Those consumer groups showed significant differences in terms of demographics and preferred store characteristics. In conclusion, Korean women aged 45-64 were shown to have some differences in their shopping orientation compared with young women and to differ in preferred store factors among their groups.

The nucleotide sequences of the internal transcribed spacer regions (ITS1 and ITS2) of ribosomal DNA (rDNA), and the 5.85 rRNA gene, have been determined for 13 strains of dinoflagellates in order to analyze the phylo-genetic relationship. The DNA sequences contained considerable variation in the ITS regions, but little in the 5.85 rDNA. In addition, the ITS1 was more variable than the ITS2 in all species examined. The nucleotide length of this region varied from 519 bp to 596 bp depending on the taxa. The investigated taxa were divided into three large groups based on the ITS length, i. e., a group with short ITS region (A. fraterculus and Alexandrium sp.), a with ITS region group (P. micans, P. minimum and P. triestinum) and a with ITS region group (G. impudicum, C. polykrikoides, G. sanguineum, G. catenatum and H. triquetra). The relationship between nucleotide length of ITS1 and that of ITS2 was negative, whereas G+C content and nucleotide length showed positive correlation. In phylogenetic analyses producing NJ trees, the topology was similar cluster and clearly divided the taxa into three groups based on 5.8S rDNA that were similar to those based on morphological characteristics. In particular, G. impudicum was more closely related to G. catenatum than to C. polykrikoides using phylogenetic analysis. From this study, we chew that the length of ITS region contributes to discriminate Korean harmful algal species and ITS analysis is a useful method for resolving the systematic relationships of dinoflagellates.

Bupleurum latissimum is a narrowly endemic and endangered plant, restricted to only two small populations on steep cliffs of a small island, Ulleung Island, in Korea. The genetic diversity and population differentiation in the two remnant populations of the species were investigated using RAPD (random amplified polymorphic DNA) analysis. The Neis gene diversities were 0.146 in the smaller population of 45 individuals, and 0.151 in the larger population of 61 individuals. The genetic variation was not significantly different between these two populations. Genetic diversity within populations was not low considering the very small size of populations. Analysis of molecular variance (AMOVA) revealed higher variation within populations (65.9%) than genetic differentiation between them (34.1%). B. latissimum revealed higher population differentiation than other outbreeding species. The differentiation of the populations corresponded to low gene flow (Nem = 0.482). The cluster and principal coordination analyses provide strong support for high population differentiation, showing that all individuals of the two populations have built up population-specific clusters. Although gene flow between the two populations of B. latissimum was limited, they have preserved relatively high levels of genetic variation.

The current study aims to segment Chinese female consumers using their lifestyle dimensions in the cosmetics market, and analyze their cosmetics purchasing behavior based on that segmentation. Specifically, lifestyle groups were examined to see if there is any group difference(s) in consumer behavior for Korean cosmetics. Lifestyle groups were examined based on: consumers' demographic characteristics, perceived brand attributes, loyalty toward Korean cosmetics, usage of Korean cosmetics products, preferred stores of shopping for Korean cosmetics, and use of information sources in purchase decisions. An online survey was administered to female consumers who live in Beijing and Shanghai. A total of 493 surveys were used for data analyses. The results of the study were as follows: First, factor analysis revealed 11 significant lifestyle dimensions. Second, using these 11 lifestyle dimensions, cluster analysis was conducted, which revealed four distinct groups of consumers: (1) "timid inactive group," characterized by having low scores in most lifestyle dimensions; (2) "showcase goers," who tend to be highly fashion/appearance-conscious and brand-oriented; (3) "practical buyers," who tend to be price-conscious, sensitive and timid; and (4) "sensible buyers," who enjoy finer meals and wellbeing lifestyles, as well as hardworking in everything and impulse-buy things. Third, consumer behavior of purchasing Korean cosmetics brands were examined; significant differences among the four lifestyle groups were found. The study concludes with a discussion of the results and practical implications.

The purpose of this study was to investigate the actual conditions and characteristics of weekly and daily child care programs for infants, to provide a basis for the improvement of infant care quality. Weekly and daily curricula of 18 classes for one and two-year-olds classes (9 for each ages) from childcare centers in D city were collected from Nov. 2009 to February 2010. The results are as following: first, classes for one-year-olds plan 6-25 activities and classes for two-year-olds plan 12-30 activities weekly, with differences in the number of weekly activities according to the childcare centers. The number of weekly activities should be planned considering infants' interest as well as educational continuity of the activities. Second, the investigation of daily activities showed that the routine activities planned for one-year-olds were for total of 310-600 minutes and for two-year-olds 310-540 minutes. Among these, on average of 66% of the time was planned for everyday life such as eating and napping. The rest of time was dedicated to indoor and outdoor free play. However a few centers allocated more time for group activities according to subjects compared to free play. A curriculum composed of group activities ignoring infants' individual developmental differences should not be encouraged. Last, the results of cluster analyses on weekly and daily curricula in terms of the number of activities and time, duration, number of group activities and time showed that curricula for infants could be characterized into two types: "free play" and "group activity" curricula.
