Study aims to identify customer equity drivers and their relative importance, to represent customer lifetime value (CLV) distribution, and to investigate the effect of customer equity drivers and demographics on CLV when shopping apparels at the four big department stores in Seoul. Recently, Korean department stores marked significant decrease in sales volume and it calls for more focus on customer orientation. Customer equity is a managerial concept which considers customers as a valuable asset for business success. Sustainable competitive advantage is attainable when customer equity drivers and CLV are measured, managed and enhanced. results identified four dimensions of customer equity drivers such as 'retail brand equity: 'relationship equity', 'retail service equity', and 'price value equity'. Among them, 'relationship equity' was proved to be the most influencing factor on the customer's store patronage intention. The CLV distribution represented unique characteristics of each department store. The level of CLV depended on such demographics as age and income. Marital status influenced the relationship between perceived customer equity drivers and CLV. It also analyzed competitive structure of the four big department stores in Seoul and offered managerial suggestions. This study provided conceptual framework for the future study of customer equity related to apparel shopping at the department stores as well as managerial implications.

음성의 인식율 저하는 주로 잡음에 의해 발생하고, 이러한 요인을 제거하기 위해 주로 필터뱅크를 사용하여 왔지만, 본 논문은 2 차원 선형예측이라는 영상 특징 추출 방법을 이용하여 잡음에 강인한 숫자 음 인식을 시도하였다. 먼저, 음성에 대한 인식결과를 도출하기 위해, 13 차 선형예측 계수를 이용하여 인식을 시도하였다. 이 때, 잡음을 추가한 음성을 이용하여 시험한 결과, 5 개의 숫자음, ‘영’, ‘사’, ‘오’, ‘육’, ‘구’에서 인식결과의 저하를 볼 수 있었다. 이러한 결과를 향상시키기 위해 2 차원 선형예측 계수를 추가한 인식기 입력 데이터를 구현하였다. 이 때, 선형예측 계수는 각 프레임별로 추출하였고, 음성데이터와 합한 영상 데이터를 가지고 인식 실험을 실시하였다. 이 때, 숫자음 ‘사’ 와 ‘구’ 에 대해서는 상당한 향상을 보였다.

Root-knot nematodes cause billions of dollars in crop losses annually have a broad range of host over 2,000 species of plants. These nematodes are known as obligate, sedentary endo-parasites in a plant host to feed upon to complete their life cycle. To prevent the plant parasitic nematode, methyl bromide was widely applied as a soil fumigant. Other strategies to prevent or control nematodes involve RNAi-mediated suppression, R gene transformation, natural products or chemical treatments, the expression of peptide or proteins in susceptible plants, and others. Over the last decade, the entry in GenBank for Meloidogyne reveals 73,340 ESTs and recently two complete Meloidogyne spp. genomes sequences have simultaneously been presented by two groups. Recent works have demonstrated the effect of RNAi suppression to nematode target genes. These results will provide novel members of genes as a foundation for studies focused on understanding the function of M. incognita nematode genes as well as for the development of novel target genes for parasite control. Thus the successful development of biotechnology-derived plants with nematode resistance will result in large yield benefits for producers as well as environmental benefits and will accelerate the research related to pathogensresistant crops.

Antioxidative activities of Chlorophyta and Phaeophyta in Jeju Island were measured by superoxide anion ($O_2^{{\cdot}-}$), hydroxyl radical ($HO^{\cdot}$), hydrogen peroxide ($H_2O_2$) and DPPH free radical scavenging assays. Methanolic and aqueous extracts of the seaweeds were prepared at both temperatures, higher (70$^{\circ}C$) and room temperature (20$^{\circ}C$), and screened for the construction of an extract bank from seaweeds in Jeju Island. A variety of extracts showed positive effect against reactive oxygen species (ROS). Especially, Sargassum thunbergii methanolic extract at 70$^{\circ}C$ (70ME, 97.41%), S. fulvellum methanolic extract at 20$^{\circ}C$ (20ME, 84.66%), Codium fragile aqueous extract at 70$^{\circ}C$ (70AE, 96.61%) and S. thunbergii 20ME (97.44%) exhibited the highest scavenging activities against $O_2^{{\cdot}-}$, $HO^{\cdot}$, $H_2O_2$ and DPPH free radicals, respectively. Total phenolic contents also examined but did not show a positive correlation with ROS scavenging abilities (except for a few extracts). These results indicate that further investigation is needed to identify and purify the responsible antioxidative components.

Availability of feeds and fodder and amount of their intake by large ruminants in eight different agro-ecological zones (AEZ) of Bangladesh were recorded over a year. Roughages such as straw, naturally grown green grass, water hyacinth, tree leaves, legumes and sugarcane tops were the major feedstuffs fed to the large ruminants. Amount of intake of these ingredients differed (p<0.01) across AEZ studied, but did not differ across seasons or farmers' categories (p>0.05) except for green grasses (p<0.01). Byproduct concentrates offered to animals in the studied areas were rice bran, wheat bran and different oil cakes. The amount of intake of concentrates by the animals also differed (p<0.01) across AEZs, but did not differ across seasons or farmers' categories (p>0.05), except for rice bran and wheat bran which differed between season and farm category, and season respectively (p<0.01). The large standard errors of mean indicate that there are wide variations in intake of roughages and concentrates across AEZ's, seasons and farmers' categories and even across days. This further indicates that the feeding practices of large ruminants are largely heterogeneous. In addition to feeding roughage and concentrates, the animals were allowed to graze for six hours a day. Grazing hours also differed (p<0.01) across AEZ, but not by farmers' categories or seasons.

본 논문에서는 웨이블렛 서브밴드 필터링기법을 이용하여 다중의사 결정기법에 기반을 둔 잡음에 강인한 화자식별 알고리즘을 제안한다. 제안된 방법은 잡음이 첨가된 음성신호를 웨이블렛 서브밴드 필터뱅크를 이용하여 각 주파수 대역별로 신호를 분리한 후 개별적인 대역별로 인식 알고리즘을 수행하기 때문에 어떤 서브밴드에서의 노이즈 영향이 상대적으로 적으므로 대역제약된 형태로 주어지는 일반적인 주변잡음이 있는 환경하에서 우수한 성능을 보일 수 있도록 시스템을 구성하였다. 제안된 알고리즘은 화자인식 기법으로 널리 쓰이고 있는 벡터양자화 알고리즘만을 적용한 경우에 비해 15∼60%의 향상된 인식률을 보였다.

The purpose of this paper is to investigate the impact of total factor productivity (TFP), institutional quality, and interactive variable between them on economic growth in 13 low-middle income countries in Asia for the period 2000-2018. The paper uses the difference Generalized Method of Moments (GMM) to explore the dataset provided by the World Bank. The empirical results show that TFP and the interactive variable positively impact on the economic growth, while the institutional determinants have a negative influence. The negative effect is explained by the weak institutions in these low-middle income countries. The findings of the study suggest two points. First, the government should continue to improve TFP, which is associated with the application of technical advances, technological innovations, improvement of management methods, and skilled workers. Second, far more important, is that the authorities should pay special attention to implement institutional reform and strengthen the governance in the future. The successful experiences from Japan, Korea and Singapore will help other governments in Asian low-middle income countries to build developmental state. Probably, the developmental state actively interfere in the market to promote and realize the development goals. By doing so, these economies might overcome the so-called "middle-income trap".

Purpose: Vascular endothelial growth factor (VEGF) is known as a growth factor of endothelium and fibroblast. The purpose is to know the VEGF effects on fibroblast proliferation and fibroblast's notch receptor expression. Methods: CCD-986sk fibroblast was purchased from the Korean Cell Bank and was used in XTT assay for proliferation and wound healing assay for migration. Immunofluorescent (IF) staining and western blotting were used in testing notch expression of fibroblast. Semiquantitative RT-PCR was used in checking notch 1 mRNA production by fibroblast. Student-t test was used for analyzing results. Results: Cell proliferation assay using XTT showed significant higher proliferation in VEGF treated fibroblast, $2.324{\pm}0.0026$ vs. $2.463{\pm}0.017$ (p=0.002). Wound healing assay showed longer migration in VEGF treated fibroblast (p=0.062). The fluorescence was brighter in VEGF treated cells of notch 1 IF staining. Notch 1 expressions and mRNA productions increased more in VEGF treated cells. Conclusion: VEGF stimulates fibroblast to proliferate, migrate and to express Notch 1 simultaneously. Notch receptor could be related to VEGF mediated wound healing.
