  • In this paper, we propose a CPLD low power algorithm considering the structure. The proposed algorithm is implemented CPLD circuit FC(Feasible Cluster) for generating a problem occurs when the node being split to overcome the area and power consumption can reduce the algorithm. CPLD to configure and limitations of the LE is that the number of OR-terms. FC consists of an OR node is divided into mainly as a way to reduce the power consumption with the highest number of output nodes is divided into a top priority. The highest number of output nodes with the highest number of switching nodes become a cut-point. Division of the node is the number of OR-terms of the number of OR-terms LE is greater than adding the input and output of the inverter converts the AND. Reduce the level, power consumption and area. The proposed algorithm to MCNC logic circuits by applying a synthetic benchmark experimental results of 13% compared to the number of logical blocks decreased. 8% of the power consumption results in a reduced efficiency of the algorithm represented been demonstrated.

  • The purpose of this study was to investigate the consumption patterns of the Korean traditional rice cakes by general public. Self-administered questionnaires were collected from 511 residents in the Metropolitan area. Data were analysed by t-test, ANOVA and Chi-square. The result of the study can be summarized as follows: Generally, the rice cake was recognized as a 'good food' in all age groups. The reasons why they prefer the rice cakes were 'It tastes good' and 'It has been eaten from the past.' The time when they use the rice cake was mostly the holidays and events(or festivities). The female had more experiences than the male in making it. Songpyeon took the first place for them to have experiences to make. The consumption frequencies of rice cake were the more in females than in males. The higher the age, the more frequently they consumed. Injeolmi was the one which was purchased the most frequently. The place that they usually buy from was the rice cake shop around their house. The most important factor considering when they buy it was the taste. The reason why the frequency the rice cakes made for their direct consumption at home is gradually decreasing was "It is troublesome to make", and "It is complicated to make.

  • This study attempts to evaluate and compare the land consumption efficiencies of various urban transport modes, utilizing the time-area method. With the careful considerations of travel conditions and modal characteristics, equations for the computation of time-area for various different modes are derived. With the appropriate assumed values of parameters, time-area consumptions per person per km for each mode both for peak and off-peak situations are computed and evaluated. The relationships between the time-area consumed and operating speed for each mode are graphically demonstrated and discussed. An example of the time-area consumed for a hypothetical commuter round-trip using various modes are also presented in order to clearly show the consumption of parking requirements by specific modes. It shows that regardless of facilities used, auto users are by far the worst in terms of area efficiency and that transit, especially rail rapid transit, is a superior mode. Pedestrian and bicycle, though consuming more than expected, also demonstrate the advantage in case of a short-distance trip in terms of area efficiency compared with the bus transit modes.

  • This paper proposes an asynchronous circuit design methodology using a new Single Gate Sleep Convention Logic (SG-SCL) with advantages such as low area overhead, low power consumption compared with the conventional null convention logic (NCL) methodologies. The delay-insensitive NCL asynchronous circuits consist of dual-rail structures using {DATA0, DATA1, NULL} encoding which carry a significant area overhead by comparison with single-rail structures. The area overhead can lead to high power consumption. In this paper, the proposed single gate SCL deploys a power gating structure for a new {DATA, SLEEP} encoding to achieve low area overhead and low power consumption maintaining high performance during DATA cycle. In this paper, the proposed methodology has been evaluated by a liquid state machine (LSM) for pattern and digit recognition using FPGA and a 0.18 ㎛ CMOS technology with a supply voltage of 1.8 V. the LSM is a neural network (NN) algorithm similar to a spiking neural network (SNN). The experimental results show that the proposed SG-SCL LSM reduced power consumption by 10% compared to the conventional LSM.

  • The purpose of this study was to investigate the relationship between alcohol consumption and nutritional status of university male freshman in Chungnam area. The total of 111 subjects took part in the study and, they were observed general characteristics, alcohol consumption status, and nutrient intake using questionnaires. The mean age, height, weight, and BMI of the subjects were 19.3 years, 174.3㎝, 65.2㎏, and 21.5㎏/$m^2$ respectively. The mean alcohol consumption, and energy intake from alcohol were 7.8g/day, 55.3kcal/day. A significant number of subjects(48.2%) answered their frequency of alcohol consumption was once 2 weeks. Only 4.6% of subjects answered never drink. In almost subjects, alcohol consumption have been stared since they were adolescents, and major type of alcoholic beverage was 'soju'. The mean energy intake was 1985.6kcal and, energy ratio from carbohydrate, protein, fat was 58 : 15 : 27. There were significantly positive correlation among alcohol consumption and, body weight(p<0.05), intake of food, (p<0.05), energy(p<0.001), animal fat(p<0.05), fiber(p<0.05), vitamin $B_2$(p<0.05) and niacin(p<0.05). The alcohol consumption period showed a significantly positive correlation with alcohol consumption per one time(p<0.05). In summary, high consumption of alcohol in subjects was observed. Also, increase of alcohol consumption was related to weight gain and nutritional imbalance. Therefore, it is need that nutrition education for prevention of high alcohol consumption in university freshman and adolescents.

  • Purpose - Food consumption in Korea has changed in paradigm as it has grown qualitatively in the past in quantitative shortages. Consumer food consumption patterns are rapidly changing due to changes in economic, social and population conditions, scientific and technological development, climate change, and market opening. At the same time, there is a need to actively respond to these changes in terms of the food industry, market, and government policy. The purpose of this study is to examine the changes and characteristics of food consumption expenditure of Korean consumers in-depth and depth in order to provide implications for agriculture, food market and policymakers. Research design, data, and methodology - We analyzed various food consumption changes from the 1980s to 2015 through Household Income and Expenditure Survey raw data from MDIS(Microdata Integrated Service) of Statistics Korea. and conducted the age effect, generation effect, and year effect by cohort analysis. We also conducted comparisons with OECD countries on several indicators. Results - Food consumption spending was slow, and there was no significant change in home consumption, while eating out consumption increased about 20 times in 2015 compared to 1980. Income, age, residential area, number of household members showed significant changes in food consumption. According to the cohort analysis, the changes in the food consumption structure are largely due to age effect, and the year, age, and generation effects are different for each food item. Conclusions - Food consumption has a significant impact on not only the nutritional status of consumers but ultimately the public health. Therefore, they should be regarded as a strategic policy area of central government rather than a matter of size and change of food consumption expenditure.
