This paper describes a systematic process which can generate a complete circuit specification efficiently for a given recursive DSP algorithm based on an optimal multiprocessor scheduler. The process is composed of two states: scheduling and circuit synthesis. The scheduling part accepts a fully specified flow graph(FSFG) as an input, and generates an optimal synchronous multiprocessor schedule. Then the circuit synthesis part translates the modified schedule into a complete circuit diagram including a control specification. The circuit diagram can be applied to a silicon compiler for VLSI layout generation. This paper illustrates the whole process with an example of a second order Gray-Market lattice filter.

This study is to present practical plan to stimulate Parallel Import Policies, Which is one of the government policies to drop import prices of imported goods. Although, preliminary studies focused on legal aspects related to Intellectual Property Right, from the perspective of trade, we conducted a study on economic aspects through parallel import, consumer welfare, etc. For this study, the parallel import system of the United States and Japan was compared with Korea and the domestic parallel import market status was analyzed by comparing market price. According to the study, the current parallel import system lacked the limits of government regulation and distribution market structure. It proposed practical plans such as political suggestions and changes in distribution structure. This study is meaningful in analyzing the problem of parallel imports that currently occur in the Korea market based on data concerning parallel imports in practical terms

More than 90% of cultured fish is consumed by sliced raw fish which is usually an eating out menu in South Korea. In order to develop the aquaculture industry in Korea, It is very important to know whether consumers can differentiate each species or not and how consumers recognize each species by certain criteria. for example taste, seasonal preference. The purpose of this study is to understand the competitive relationship through positioning studies of each species by the selection attributes. A total of 221 consumers were surveyed in korea. This study adapted multidimensional scaling(MDS) analysis to explore how consumers position sliced raw fish species based on selection attributes. This study has produced perceptual maps of sliced raw fish market. Empirical data was collected from sliced raw fish consumers in Korea. The results of MDS analysis reveal that 7 species are divided into 3 groups(flat fish, black rock fish), (red sea bream, salmon, tuna), (sea bass, gray mullet). In this study flat fish and black rock fish are perceived as safe, familiar, good value species. Red seabream, salmon, tuna are perceived as luxurious species. Sea bass and gray mullet are perceived as unfamiliar species.

This study proposes controller with voltage-compensated drivers for producing gray-scaled pictures on passive matrix organic light emitting diodes (PMOLEDs) panels. The controller includes voltage type drivers so the output impedance of the driver is far less than that of the current-type driver. Its low output impedance provides better electron-optical properties than those of traditional current drivers. A free running clock and a group of counters are applied to the gray-scaled function so that phase lock loop (PLL) circuit can be reduced in the controller. A pre-charge function is used to enhance performance of the luminance of an active OLED pixel. As a result, distribution of the low gray level portion is achieved linear relationship with input data. In this work, the digital part of the proposed controller is implemented using FPGA chips, and analog parts are combined with a digital-analog converter (DAC) and analog switches. A still image is displayed on a $48^{\ast}64$ PMOLEDs panel to assess the luminance performance fir the controller. Based on its cost requirement and luminance performance, the controller is qualified to join the market for driving PMOLEDs panels.

Because bacterial isolates from only a few genera have been developed commercially as biopesticides, discovery and characterization of novel bacterial strains will be a key to market expansion. Our previous screen using plant bioassays identified 24 novel biocontrol isolates representing 12 different genera. In this study, we characterized the 3 isolates showing the best biocontrol activities. The isolates were Pantoea dispersa WCU35, Proteus myxofaciens WCU244, and Exiguobacterium acetylicum WCU292 based on 16S rRNA sequence analysis. The isolates showed differential production of extracellular enzymes, antimicrobial activity against various fungal or bacterial plant pathogens, and induced systemic resistance activity against tomato gray mold disease caused by Botrytis cinerea. E. acetylicum WCU292 lacked strong in vitro antimicrobial activity against plant pathogens, but induced systemic resistance against tomato gray mold disease. These results confirm that the trait of biological control is found in a wide variety of bacterial genera.

This paper examines the relationship between information risk and equity premium in the Korean stock market. We use accruals quality as a proxy of information risk. Accruals quality (AQ) is estimated by Dechow and Dichev (2002) model, and then AQfactor is constructed based on the estimated AQ. Time-series and cross-sectional regression models are used to examine the relationship between information risk and equity premium, reflecting the critics of Core et al. (2008). The result of the paper shows that information risk proxied by accruals quality is not priced in equity premium in the Korean stock market. This result is consistent with Core et al. (2008) for US firms, but different with Francis et al. (2005) for US firms and Gray et al. (2008) for Australia firms. Also, the result shows that AQfactor is closely correlated with firm characteristic variables such as firm size. This implies that the effect of AQ on equity premium is more likely to arise from the pricing error due to firm characteristics rather than from an unknown risk factor.

The purpose of this study was to examine the sportswear purchase decision factors and brand preference of college students. The subjects in this study were 614 college students who were selected by cluster random sampling from Daegu and North Gyeongsang Province. The collected data were analyzed by crosstab analysis, and the findings of the study were as follows: If a sportswear company has college students as a target market, first, the company needs to consider design and utility. Second, the company needs to expand internet sale while maintaining a strategy for centering on speciality shop and department store as for a sale of sportswear. Third, the college students themselves have a right of choice according to purchasing sportswear. Thus, a distribution company requires a direct marketing strategy targeting college students. Fourth, simple design of adding a fashion trend is needed. Fifth, the sportswear company needs to expand production and sale in jumpers and trousers based on T-shirts. Sixth, color in sportswear needs to be composed of design based on gray or black color. In order for a sportswear company to be adjusted to the global market environment here after, it requires an effort to continuously grasp consumers' trend and to apply new design and color. Also, the company will be able to be equipped with competitive edge by producing diversely functional products that are demanded by the segmented market.

This study aims to investigate the characteristics of Chinese consumers, who are growing up as the global biggest consumption market, according to G sensibility types, and to provide the data base for China market by analyzing the consuming pattern per sensibility and the preferred color. For the investigation, the survey on G sensibility and consuming pattern was conducted for consumers in four cities of China. As a result of classification of G sensibility types, it was found that Chinese consumers tended to behave in accordance with their values and identities and the most general type in them was G1 pursuing the reasonable and logical consumption, unlike Korean consumers who tended to be shown as G3 for the most general type according to the preceding study. As to characteristic of consumption, Chinese consumers preferred to purchase clothes from the department store, and in case of G2 type, the characteristics was corresponded with Actionist's character which shows the wide range of behavior and high-consumption, by preferring the road-shop next to the department store. Chinese consumers tended to purchase the clothes on the basis of their preferred colors, and especially it was shown that achromatic color was very commonly preferred. Also the black color was on the highest preference, and white, dark gray and light gray were followed. Meanwhile, in chromatic color, it was found that brown, orange, red and blue were preferred in order, and in case of G4, it was found that they preferred more various colors compared to the other types. This result could be used as the data base for the marketing strategy of fashion design industry and the related companies, as well as the new communication method for the consumers.

The study investigated trends in wall-covering displays in interior design stores. Although studies reported design trends at well-known exhibitions overseas such as Heimtextil and Maison objet, many different cases present actual realistic design flows. This study analyzes the actual market flow rather than design as an exhibition concept, and presents the interior CMF trends in 2019. The CMF design of wall-covering displayed in New York D&D Building in 2019 can be summarized as follows: W was the most frequently seen show-window, but like R, which is a strong color, it is also used to convey surrealistic images. The store entrance was designed to attract consumers' attention inside, and was constructed to reflect the actual trend. In the 2019 New York market, the wall-covering of Gray and YR were displayed through the shop entrance to suggest substantial sales. In addition, the demand for gold metallic wall-covering is significant as gold was strong in many forms. This study represents a valuable resource to identify trends in wall-covering from 2017 to 2019 compared with previous studies. This study represents a valuable foundation for a wide range of topics related to the use of wall-covering for interior decoration.
