  • This study was performed to investigate the influence of seafood education on students' preferences and perceptions towards seafood menu items provided by school foodservice. The 62 representative menu items were selected from the complete menus provided by 10 high schools located in the Daegu Kyungpook area. Five hundred students were surveyed and 484 questionnaires were analyzed. The preference ($3.25{\pm}0.92$) of seafood menu items was not sufficiently high. The preference order of seafood menu items was rice > noodle > deep fry > grill> stir fry > seasoned dish > soup/stew > steam > pan fry > braise > fermented fish. Conversely, the most frequently provided menu items were soup/stew (31.34%), braise (18.06%), stir fry (15.61%), and seasoned dish (14.83%); the results showed no significant correlation between students' preference and the frequency with which the items were provided. Seafood education positively influenced the students' preference (p<0.001) and perceptions of the seafood acceptability (p<0.01), nutritional value (p<0.05), menu variety (p<0.05), diversity of cooking methods (p<0.001), cleanliness (p<0.001), and leftover amounts (p<0.01). However, more than half the students participating in this study have never received any type of education on seafood. Therefore, a practical program for seafood education should be developed to promote seafood consumption among young students.

  • Objectives There were previous studies which indicated that attitude toward suicide is able to influence the suicide outcome in both individual and group levels. In regard to the highest suicide rate in Korea, our study aims to explore the influence that attitude toward suicide has on suicide by comparing the national attitude towards suicide with a representative sample of the general population. Methods The target population was 20- to 59-year-old adults from South Korea, Japan, and the United States. The panel data were divided according to gender, age, and residential area of individuals, and an email with a hyperlink to our web survey was sent to the randomly selected participants in each stratum. To measure the perceptual differences about suicide in different cultures, this study adopted the Attitudes Toward Suicide questionnaire. Results A total of 2247 subjects in three countries participated in this study. According to results from factor analysis, there were different structure of factors and included items within factors in the three countries : five factors with nineteen items in South Korea, five factors with nineteen items in the United States, and five factors with twenty-five items in Japan. With regard to permissive attitude toward suicide, the mean value of permissiveness was not significantly different among countries, but permissiveness according to education level, gender, and marital status was different in each country. Conclusions This study is the first nationwide comparative study about attitude toward suicide with a representative sample. Our findings suggest that permissive attitude toward suicide influence the suicide phenomenon in each country ; however, its impact is not a mean score of permissiveness, but the detailed difference by various demographics.

  • In the current study, we measured the hands and other representative body items of 223 elementary school girls using Martin Anthropometer and a digital camera so that we would be able to provide information on both size and shape of hands for design of hand-related products. As time goes on, hands get bigger, yet they get thinner at the same time. The data implies that the frame of hands grows, but the skin fat lessens, which could be a determinant factor in the size system of hand-related products. According to the results of a factor analysis on 26 hand items, 5 factors including hand laterality and linearity, fingertip shape, finger breadth, and hand depth, have been extracted. Pearson's correlation showed that most of hand-related factors were strongly associated with other body items. Finger breadth and hand depth, however, were found less related to other body items. The ANOVA test used in testing the difference of hand factors showed, in most items, a difference by ages, but there was no significant differences in fingertip breadth, the third factor, Interestingly, in hand depth, the fifth factor, lower grade girls' hands were thicker than higher grade girls'. This research suggests that the size system of uniformly increasing the size of all hand parts by age groups should be reconsidered and leaves much for improvement.

  • This study develops size sections and specifications for females 7-18 years old. The specifications will contribute to the development of precise virtual models that represent basic data for the size alteration of 3D virtual models. A total of 33 items from the $5^{th}$ Size Korea data set were adopted and analyzed. Two representative factors (Obesity and Height Factors) were identified through a factor analysis of the 33 items. Waist circumference and stature were selected as representative variables for Obesity and Height Factors, respectively, and conducted cross tabulations between waist circumference and height for the age groups of 7-12 and 13-18 year-olds. Size sections were developed for the development of 3D models based on the results. A regression analysis then developed size specifications for each section with independent variables of waist circumference and height as well as dependent variables of reference body size. Subsequently, Obesity Factors were better explained by waist circumference and Height Factors were better explained by stature. Finally, size specifications for each section were developed.

  • The purpose of this study is to analyze the image of color combination in fashion design. For this study 14,121 color samples were collected from 116 fashion brands selected by the market segmentation based on the results of the previous studies. The brands have high market share and brand recognition in each segmental market. The color samples were measured by spectrophotometer and analyzed by the Munsell's H V/C and CIE $L^*a^*b^*$ value. The representative colors of each market were selected concerning the tensity in CIE $L^*a^*b^*$ color space and the distance between the color samples. h4 a result, 2,213 representative colors were chosen. These color samples composed top and bottom color combination samples by the program 'Item Comparator' that calculated the color differences$({\Delta}E^*)$. Top includes the items such as blouse, shirt, and coats, bottom includes the items such as skirt and pants. The color combination samples were divided into two groups. In one group ${\Delta}E^*$ was less than 30, and In the other group ${\Delta}E^*$ was 30 or more. For investigating the image of color combination, 480 rotor combination samples were classified. The image adjectives for the survey from preceding studies and brand dictionaries were 'classic', 'modern', 'feminine', 'casual', and 'romantic', which have highly preferred in women's wear brands. The result of the study is as follows; For 'classic' 'image, YR, and greyish tone were generally preferred. In the color combination of 'casual' image, the samples with PB color and greyish tone were preferred. For 'feminine' image, RP was preferred as a top color, R, RP, P were preferred as a bottom color. For 'casual' image, PB was preferred as a top color, PB, B were preferred as a bottom color. For 'romantic' image, RP was preferred as a top color, R, P were preferred as a bottom color. The bigger the color differences between the color combination samples were, the more remarkable the image of color combination samples was.

  • This study explored public awareness and donning practices of traditional and religious dresses among Indonesian Muslim. The relevant literature was reviewed first, and in-depth interviews and survey were followed to achieve the purpose of the study. Sarung and Kain Panjang are the most representative unisex traditional clothing of Indonesia. Traditional male dresses include Kemeja Batik, Beskap, Peci(Kopiah) and Blangkon. Traditional female dresses include Kebaya, Baju Kurung, Baju Bodo, Kemben, Rok Batik and Slendang. Baju Koko, Sarung and Peci(Kopiah) are the most well-known Muslim male dress items. Muslim female dresses are more diverse than men's. For traditional and religious dresses, which were identified from literature study, public awareness and donning practices were examined with survey data. Indonesian people consider Kebaya, Sarung, and Batik as the most important traditional dresses which convey national identity. Peci(Kopiah), Baju koko, and Jilbab(Kerudung) are highly mentioned as the representatives of Muslim dresses. Indonesian Muslims report that they own these representative dresses commonly. Peci and Sarung are included both in religious and traditional dresses, demonstrating that the two items are the representative crossovers of their religion and the tradition of the country. For both traditional and Muslim dresses, Indonesian people think that aesthetics and traditional values are more relevant than practical value. Lastly, it is found that traditional dresses are parts of the daily wear of Indonesian people from the fact that they wear traditional dresses more than once a week.

  • 데이터마이닝 기법들은 의미 있고 유용한 정보를 효율적으로 찾기 위해서 제안되어 왔다. 특별히, 빅 데이터 환경에서 데이터가 여러 응용들에서 축적되어짐에 따라, 관련된 패턴 마이닝 방법들이 제안되고 있다. 최근에는 파일이나 데이터베이스에 이미 저장되어 있는 정적 데이터를 분석하는 대신에 점진적으로 생성되는 동적 데이터를 마이닝 하는 것이 더 흥미 있는 연구영역으로 고려되고 있는데 동적데이터는 단지 한번만 스캔하여 읽을 수 있기 때문이다. 이와 같은 이유로, 어떻게 동적 데이터를 효율적으로 마이닝 하는지에 대한 연구들이 진행되고 있다. 더불어서, 마이닝 결과로 거대한 수의 패턴들이 생성되기 때문에, 맥시멀 패턴 마이닝과 같은 대표 패턴들을 마이닝하는 접근방법들도 제안되고 있다. 또 다른 이슈로, 실세계에서 더 의미있는 패턴들을 발견하기 위해, 가중화 패턴 마이닝에서 아이템들의 가중치가 사용되고 있다. 실제 상황에서 아이템의 이익이나 가격 등이 가중치로 사용 될 수 있다. 본 논문에서는 점진적으로 생성되는 데이터에 대한 가중화 맥시멀 패턴 마이닝, 맥시멀 대표 패턴 마이닝 그리고 점진적 패턴 마이닝 기법들에 대해 분석한다. 그리고 가중화 대표 패턴 마이닝을 적용하여서 유아들에게서 필요로 하는 물품 패턴들을 분석하기 위한 응용 시나리오를 제시한다. 추가로, 분석한 마이닝 알고리즘들에 대한 성능 평가를 수행한다. 결과적으로, 점진적 가중화 맥시멀 패턴 마이닝 기법이 점진적 가중화 패턴 마이닝과 가중화 패턴 마이닝 기법보다 좋은 성능을 가짐을 보인다.

  • 한국형 TDS에 필요한 차별화된 포괄적인 식품목록을 도출하기 위해, 가장 최근에 실시된 2009년 TDS에서 사용된 것과 동일한 식품섭취량 자료를 사용하여 대표식품 선정기준을 확대 보완하고 그 결과를 비교하였다. 식품별 섭취량 누적비율 90%까지 확대, 섭취빈도 5% 이상으로 확대 및 추가 고려요인으로 지용성 오염물질을 위한 지방섭취량 누적비율 80%까지에 포함되는 식품을 고려하여 총 161종의 식품이 선정되었다. 도출된 대표 식품 목록은 우리 국민이 2007년에 섭취한 것으로 조사된 모든 식품군을 포함하고 있어 그 포괄성이 입증되었다. 다음 단계로, 한국인의 일상적인 식이를 대표할 수 있는 식품섭취량 자료를 확보하기 위해, 총 18,022명을 대상으로 실시된 2008년도와 2009년도 국민건강영양조사의 식품섭취량 자료를 통합하고 여기에 등장한 687종 식품을 이용하여, 상기 기술된 선정기준에 따라 165종 식품을 선정하여 기본목록을 작성하였다. 이들을 식품군별로 분류한 후 유사식품의 중복선정을 피하기 위해 매우 유사한 식품 30종에 대해 각 식품군 내에서 다소비 순위와 다빈도 순위를 비교하여 상대적으로 순위가 낮은 식품 15종을 제외시키고, 각 식품군에서 대표식품으로 선정되지 않은 식품에 대한 검토를 통해 식품 구성과 성상이 현저히 달라서 mapping이 어려운 식품 10종을 추가하여 160종이 대표식품으로 최종 선정되었다. TDS 분석대상으로 최종 선정된 160종의 식품목록은 식품섭취량의 90.93%, 에너지 섭취량의 91.36%, 지방섭취량의 89.05%를 포괄하는 것으로 나타났다. 예산과 연구기간의 제약으로 모든 식품이 분석될 수는 없으므로 분석되지 않은 식품을 가장 유사한 대표 식품의 유해물질 분석결과에 매칭하는 방법인 'best-fit' mapping 과정을 적용한다면 유해물질별 총 섭취량의 산출이 가능하게 될 것이다. 본 연구에서는 우리 국민의 식생활을 반영할 수 있는 대표성 있는 식품섭취량 자료를 확보하여 체계적인 방법으로 대표 식품을 선정하고, mapping을 통해 모든 식품을 포괄할 수 있는 방법을 제시함으로써 유해물질별 총 노출량을 평가할 수 있는 기반을 마련하였다.

  • Due to the continuous change of socio-economic circumstances and dietary pattern, the need to change recommended dietary allowances and the basic food groups has been required. Consequently, there have been six revisions of the Korea RDAs, the national recommanded dietary allowances. I reviewed the six sequences of revisions concerning the basic food groups. Up to the fifth revision, the ranks of the basic food groups were based upon the dietary needs of the people of the perspective era. However, in the sixth revision, there was no rank associated with the food groups, but the food groups were portrayed in a food composition tower that explained their importance and their necessary consumption amounts. I could indirectly observe the dietary pattern of each era by analyzing the basic food groups and the representative foods of each food group. I also studied information of pictorial representations of the basic food groups and compared the items of the representative foods with nutrient analysis table. By observing nutrient analysis table, I analyzed whether the clarified representative foods of the basic food groups are indeed foods that were eaten frequently by people daily.
