The objectives of this study were to identify the dietary patterns associated with hypertension among Korean males. Data from the 2001 Korean National Health and Nutrition Survey of 1,869 men aged 20-65 years were used for the analysis. As an initial analysis, a factor analysis was applied to identify major dietary patterns among the subjects. Then logistic regression analysis was conducted to identify the pattern related with hypertension. As a result of the initial analysis, three major dietary patterns were identified. Dietary pattern 1 (traditional) was heavily loaded with vegetables, fish and cereal. Dietary pattern 2 (Western) was loaded with fast foods, bread, meats and dairy products. Dietary pattern 3 (Drinker) was loaded with mostly pork, beer and soju (Korean liquor). From the second stage of the analysis, there was a tendency of positive association between traditional patterns and hypertension risks. However, the tendency did not meet statistical significance level (p<0.05). In summary, unlikely findings from European and American studies, vegetables rich traditional dietary patterns did not show any protective effect on hypertension in Korean males. The Korean dietary practice, which is consuming salted vegetables instead of fresh vegetables, might have played a role in these findings. However, the full explanation of the findings remained to be answered with further investigation since none of the dietary patterns identified showed any statistical significance.

The object of this study is shape finding and cutting pattern generation of membrane structures under the following assumptions : (1) material is linearly elastic (2) stress state is plane stress. Cable and membrane structures should introduce the nonlinear analysis considering geometric nonlinearity because these structures deform largely under the external loads. The analysis procedure is consisted of three steps considering geometric nonlinearity unlike any other structures. First step is the shape finding analysis to determine the initial equilibrium shape. Second step is the stress-deformation analysis to investigate the behaviors of structures under various external loads. Once a satisfactory shape has been found, a cutting pattern based on the shape finding analysis may be generated from the view point of construction. In this paper, (1) shape finding analysis formulation and an example, (2) cutting pattern determination procedure using weighted least-square minimization flattening method and some results are presented.

Recently, information providing service using Big Data is being expanded. Big Data processing technology is actively being academic research to an important issue in the IT industry. In this paper, we analyze a skilled pattern of welder through Big Data analysis or extraction of welding based on R programming. We are going to reduce cost on welding work including weld quality, weld operation time by providing analyzed results non-skilled welder. Welding has a problem that should be invested long time to be a skilled welder. For solving these issues, we apply connection rules algorithms and regression method to much pattern variable for welding pattern analysis of skilled welder. We analyze a pattern of skilled welder according to variable of analyzed rules by analyzing top N rules. In this paper, we confirmed the pattern structure of power consumption rate and wire consumption length through experimental results of analyzed welding pattern analysis.

Countries have different brassiere patterns, and this study produced and compared 3/4 brassiere patterns from different countries to determine the difference in patterns, and to investigate the stress distribution and shape of cross section while wearing brassieres using 3D virtual fitting system. Despite the growing interest in underwear, there is a lack of related books and research on brassiere patterns, which causes the difference in sizes and pattern drafting methods by countries. Thus, research on this is needed. 3D virtual fitting system has been introduced to compare patterns, thereby improving visible effects and reducing the loss in cost caused by underwear pattern fitting test. According to the result of pattern analysis, The Secoli type exhibited the least breast cover rate (14.9 cm), while the largest cover rate was shown in Christina and ESMOD types (17.7 cm). It is believed that the difference in pattern drafting causes the difference in the total length of a brassiere. Furthermore, the Secoli, Moda Burgo, and ESMOD brassieres drafted from basic bodice pattern were found to be longer than the Christina and Han Sunmi brassieres attained from direct pattern drafting. Moreover, the darts' volume of upper and lower cups in Christina and Han Sunmi types was similar in shape. The shapes of cradle drafted from basic bodice pattern were a straight line, while those from direct drafting formed a curved shape. In fitting multiple cross sections, the Secoli, Moda Burgo, and ESMOD brassieres had gaps between the brassieres and the body. Among these, the largest number of gaps was observed in the ESMOD type pattern. This study aimed at performing comparative analysis of various brassieres' pattern drafting types as a basic research for developing a brassiere pattern drafting type.

The purpose of this study was to develop the pattern drafting method which would be suitable for their physical characteristics for the fatty body of Korean elementary school boys who re more than 1.5 Rhrer's Index. The procedures of the study were as follows : We have surveyed the rate of fatty children who were more than 1.5 Rhrer's Index on 2, 185's and elementary school children. The result of research showed the rate of fatty boys in 9-11 years-old were the highest one. Therefore, body measurement and statistical analysis. 203's boys between the ages of 9-11 and over 1.5Rhrer's Index were measured on 25 items. Descriptives, correlation and factor analysis were computed. Fatty boys higher than standard boys, and bigger than grith and width items. 4 type of conventional pants pattern were collected . The most accepted conventional pants pattern was decided through wearing test. The new pattern was based on the most accepted conventional pattern, and developed through wearing test. After new pattern drafting , the sensory evaluation for appearance and comfort was applied to evaluate the new pattern by comparing it with the conventional pattern. The result of sensory evaluation , it was found that the new pattern was more suitable then the conventional pattern.

This study was conducted to define dietary patterns among 227 Korean American adults and 151 teenagers living in California using frequency of intake of major food groups and to examine associations of dietary patterns with selected demographic and acculturation variables. Three dietary patterns, 'healthful', 'Korean', and 'western', were identified using factor analysis. For both groups, 'healthful' pattern was characterized by high loading on milk/milk products, fruit, fruit juice, and bean/bean products. 'Korean' pattern had high loading on rice and kimchi. 'Western' pattern was characterized by high loading on meat/meat products, soda, and noodle/pasta. Among Korean American adults, women tended to have higher scores of 'healthful' pattern but lower scores of 'western' pattern, while there was no association of 'Korean' pattern with gender. The older adults were likely to have higher 'Korean' pattern score. Length of stay in the US and English levels were negatively associated with 'Korean' pattern. Korean American female adolescents had lower 'western' pattern scores than did male adolescents. Age was inversely associated with 'healthful' pattern in adolescents. The adolescents who had felt more proud of being a Korean descendant had higher scores on 'Korean' dietary pattern. The study findings support that dietary patterns are associated with acculturation variables such as length of residence in the US, English fluency, and particularly pride in ethnicity for adolescents. Further studies are needed to understand associations of dietary patterns and acculturation with health risk of ethnic groups.

An embryonic stem cell is a powerful tool for investigation of early development in vitro. The study of embryonic stem cell mediated neuronal differentiation allows for improved understanding of the mechanisms involved in embryonic neuronal development. We investigated expression profile changes using time course cDNA microarray to identify clues for the signaling network of neuronal differentiation. For the short time course microarray data, pattern analysis based on the quadratic regression method is an effective approach for identification and classification of a variety of expressed genes that have biological relevance. We studied the expression patterns, at each of 5 stages, after neuronal induction at the mRNA level of embryonic stem cells using the quadratic regression method for pattern analysis. As a result, a total of 316 genes (3.1%) including 166 (1.7%) informative genes in 8 possible expression patterns were identified by pattern analysis. Among the selected genes associated with neurological system, all three genes showing linearly increasing pattern over time, and one gene showing decreasing pattern over time, were verified by RT-PCR. Therefore, an increase in gene expression over time, in a linear pattern, may be associated with embryonic development. The genes: Tcfap2c, Ttr, Wnt3a, Btg2 and Foxk1 detected by pattern analysis, and verified by RT-PCR simultaneously, may be candidate markers associated with the development of the nervous system. Our study shows that pattern analysis, using the quadratic regression method, is very useful for investigation of time course cDNA microarray data. The pattern analysis used in this study has biological significance for the study of embryonic stem cells.

Purpose: Bacterial degeneration of sweat and increased secretion of over developed apocrine sweat gland are known causes of osmidrosis. In addition, genetic inheritance must be another important cause, because there are high incidence rates of osmidrosis in familial members. But the research about genetic inheritance has been overlooked. For this reason we studied genetic inheritance in osmidrosis patients based on pedigree analysis. Methods: We have evaluated pedigree of 52 patients who have diagnosed and treated in our hospital from January 2003 to August 2007. For making pedigrees, we have evaluated 3 generations of affected lineage from osmidrosis patients. Family members having uncertain information or those who are before puberty are excluded. In pedigree analysis, inheritance rate and inheritance pattern from parents, prevalence rate in generations and sexual prevalence are evaluated. Results: In this study, we divided pedigrees into 3 different groups according to inheritance pattern. Group A is genetically unrelated pattern with no prevalence between familial members in 7 families. Group B is weakly expressed pattern with 17 families there are genetically related but no genetic patterns are founded. In group B inheritance rate is 34% and incidence rate is 21% in 2nd generation and 22% in 3rd generation. Group C is autosomal dominant pattern with 31 families. In group C, there are no differences in sexual prevalence. Incidence rate is 43% in 2nd generation and 49% in 3rd generation. Conclusion: In this study, we have studied pedigrees of 52 families of osmidrosis patients. 60% of the pedigrees shows autosomal dominant pattern, 33% shows genetically related but no definite autosomal dominant pattern and 7% shows genetically unrelated pattern. In Conclusion, This study can be basic data for future gene analysis study of osmidrosis.
