The EM 120, a newly installed multibeam echo sounder on RM Onnuri, has several advantages over the previously installed SeaBeam 2000 in performance and thus data quality. The EM 120 system provides a bottom topographic map with high resolution by (1) increasing the number of beams, (2) increasing the across track swath range, (3) measuring the more accurate sound velocity within the water column, and (4) improving stabilization for pitching, rolling, and yawing of the ship. This study compares EM 120 and SeaBeam 2000 echo sounders in terms of the data quality from the same survey area in the Clarion-Clipperton Zone, NE Pacific. Our result shows that the EM 120 provides more precise topographic data than the SeaBeam 2000. Although overall trends of data, such as topographic direction and relief, are similar for both echo sounders, the water depths measured by the EM 120 are shallower than that of SeaBeam 2000 by 80 to 90 meters.

Marine magnetic survey were carried out at Sokotra Basin offshore Korea between latitudes $31^{\circ}$ 42'32' N and $32^{\circ}$ 46'29' N, and longitudes $123^{\circ}$ 56'26" E and $125^{\circ}$ 49'16" E in order to estimate the depth of basement complex and as well as to configure it surface and produce the thickness of sedimentary sequence at the study area. Two methods have been used for depth estimation and basement configuration: the power spectrum and the 3-D analytical signal. The estimated depths resulted from the power spectrum method range from 1.4 km to 6.0 km for deep sources (basement troughs), and from 0.3 km to 1.75 km for shallow source (basement peaks). An isopach map was prepared for estimating the thickness of the sedimentary sequence at the study area; it ranges from 1.2 to 4.66 km. The estimated depths resulted from the analytic signal method range from 1.0 to 6 km. A basement configuration map was constructed for the study area in the basin. They show a well agreement with the geology of the study area.

Since ancient times in Korea, in spite of the ranks of high and low, drink was like a all sorts of human emotions. In particular, the drought, or any weapon except when wages found the ball back to God or to buy a drink to celebrate the sixtieth birthday or marriage and feasting like mails, and the priests or the funeral, such as consciousness raising in this procedure. The country had strict rituals in ceremonial events were thereby is living up to deep. The history of the drink in the history of the past, given that the main grain farming culture has already begun since the era of gojoseon was launched remains to be seen. This has been a long history of traditional attention to clean up and organize the showing to the public hall is a nationally scarce in some areas of that era, or the facility is not large. Therefore, in this study, alcohol-related exhibits and Museum recognizes the reality of the future sake Museum architectural plans: the Foundation provides materials for that purpose.

The purpose of this study was to survey the concern for health, nutrition knowledge, and nutritional attitude of the elementary school children's mothers, to investigate the correlations among them, and to estimate their effects on the growth of their children. The questionnaire was answered by 780 mothers in the Busan area. The concerns over health and nutritional attitude were above average in all items. The perception and accuracy with respect to nutrition knowledge were 90.3% and 77.0%, respectively, and the mean score of the nutrition knowledge was 17.5 on a basis of twenty-five. This indicates that the subjects had a comparatively deep concern for health and good knowledge of nutrition, and professed a relatively desirable attitude. These results indicate a desirable dietary attitude for children as well as parents. The correlation coefficients between nutrition knowledge and a concern for health, and between nutrition knowledge and nutritional attitude were very low. This suggests that the subjects' knowledge of nutrition does not develop into practice. The correlation coefficient was high (r=.610) between the concern for health and the nutritional attitude. In conclusion, the nutrition education program for mothers should be developed to add good practice to knowledge, thus increasing the concern for health, correcting their faulty knowledge of nutrition, teaching the good nutrition, and taking a practical attitude toward the use of their present nutritional knowledge.

There is a growing global interest in food choices that could affect health. Consumer food choices are dictated by numerous factors such as attitudes, beliefs, desires and preferences stemming from psychological and physiological attributes. The present study aimed to understand consumers' internal perceptions about cream soup, cream sauce, and tomato sauce using ZMET (Zaltman's Metaphor Elicitation Technique). The 9 step ZMET interview process was conducted for a sample of 36 consumers (12 consumers for each sauce). A content analysis of the survey results was carried out. From this, 56 concepts of cream soup were derived, and 15 constructs that met with the agreement of more than one-third of the total sample consumers were extracted. These 15 constructs included 'Soft', 'Recollection', 'Familiar', 'Warm', 'Comfortable', etc. Similarly, for cream sauce, 67 concepts and 20 constructs 'Silky', 'Warm', 'Restaurant', 'Family', 'Memory', etc. were deduced. A total of 66 concepts and 20 constructs for tomato sauce 'Sourness', 'Sauce Bottle', 'Pleasant', 'Ingredient', 'Cooking', etc. were derived. The analysis of consumers' consensus maps through this study provides a deep and useful understanding of consumers and their latent needs. Also, the results of this study indicate that exploring consumers' internal perceptions is critical to understanding their healthy food choices. This can be used as basic data for formulating marketing strategies.

In the rapidly changed 21st century when the flow speed of information is so fast and the quantity of information is too much increasing, personal appearance and characteristic image-formation is highly evaluated. Nowadays personal appearance is very essential to competition and may be considered the non-linguistic expression of self-image. The beauty action of the youth is shown to follow the object which youth want to rely on or long for and it is affected by the influence of the sociocultural elements. The purpose of this study is to identify the corelation between appearance and beauty action according to the sociocultural elements of the juveniles concerning appearance and to make an inquiry into how they pursue beauty in the restrictive bound compared with the adults. As their restrictive beauty action, the practical reflection percentage of hair-style, management of face, hand and nail control will be investigated and analyzed. Furthermore this basic material of this survey was used for the development of beauty article, cosmetics and education program. With the findings of the beauty articles in which the growing generation have a deep interest, this study provided the basic materials to the customer analysis and also the reference materials to the beauty marketing.

Regional cathodic protection has significant impact on pipeline integrity management. After risk analyses of a newly built gas distribution station constructed in an area with large dwelling density, risk score was high because of potential threat caused by galvanic corrosion. Except reinforced steel in concrete, there are four kinds of metal buried under earth: carbon steel, galvanized flat steel, zinc rod and graphite module. To protect buried pipeline from external corrosion, design and construction of regional cathodic protection was proposed. Current density was measured with potential using potential dynamic test and boundary element method (BEM) was used to calculate current requirement and optimize best anode placement during design. From our calculation on the potential, optimized conditions for this area were that an applied current was 3A and anode was placed at 40 meters deep from the soil surface. It results in potential range between $-1.128V_{CSE}$ and $-0.863V_{CSE}$, meeting the $-0.85V_{CSE}$ criterion and the $-1.2V_{CSE}$ criterion that no potential was more negative than $-1.2V_{CSE}$ to cause hydrogen evolution at defects in coating of the pipeline.

We present an extensive study of the environment of galaxies with bars in the low-redshift Uni-verse, using a volume-limited sample of over 30,000 galaxies drawn from the Sloan Digital Sky Survey, with visually-determined morphological classifications and bar identifications. We use four different statistics to quantify the environment of our galaxies: the projected two-point cross-correlation function with respect to a spectroscopic sample of reference galaxies, the background-subtracted number count of galaxies in a deep photometric sample in the vicinity of our galaxies, the overdensity of the local environment estimated at ~3 Mpc scale from the three-dimensional reconstruction of the cosmic density field of the local Universe, and the membership of our galaxies in the SDSS galaxy groups to segregate central to satellite systems. We find a weak, but significant trend for early-type galaxies with a bar to be more strongly clustered on scales from a few 100 kpc to 1 Mpc, when compared to early-type galaxies without a bar. For late-type galaxies, we find less neighbours within ~50 kpc around the barred late-types when compared to the unbarred late-types. For late-type galaxies we also detect a decrease of the bar fraction for dark matter dominated systems, and finally we find no obvious correlation between the overdensity and the fraction of barred galaxies in our sample.

Development of elderly foods that improve health among the older population is needed. The purpose of this study was to investigate the preference of specific foods for development as elderly foods. A one-to-one survey method was used for data collection from 150 elderly people attending senior welfare centers. The results of the study showed that the preferred cooking materials were vegetables, meats and fishes; and preferred cooking method was soup and stew rather than deep-frying. The elderly preferred meats and seafood but they did not eat them frequently. The results of investigating the preference of specific foods including meats, Kimchi, nuts and rice cakes indicated that old people liked broiled meats, Chinese cabbage Kimchi, walnuts and nonglutinous rice cakes the most, and they did not feel comfortable with chewing the foods. Most respondents were not familiar with the elderly foods. Moreover, the most important factors affecting their choice of elderly foods were hygiene, nutrition and flavor.
