  • Objectives: This systematic review of cohort studies aimed to identify any association between specific dietary patterns and risk of colorectal cancer (CRC). Dietary patterns involve complex interactions of food and nutrients summarizing the total diet or key aspects of the diet for a population under study. Methods and materials: This review involves 6 cohort studies of dietary patterns and their association with colorectal cancer. An exploratory or a posteriori approach and a hypothesis-oriented or a priori approach were employed to identify dietary patterns. Results: The dietary pattern identified to be protective against CRC was healthy, prudent, fruits and vegetables, fat reduced/diet foods, vegetables/fish/poultry, fruit/wholegrain/dairy, healthy eating index 2005, alternate healthy eating index, Mediterranean score and recommended food score. An elevated risk of CRC was associated with Western diet, pork processed meat, potatoes, traditional meat eating, and refined grain pattern. Conclusion: The Western dietary pattern which mainly consists of red and processed meat and refined grains is associated with an elevated risk of development of CRC. Protective factors against CRC include a healthy or prudent diet, consisting of vegetables, fruits, fish and poultry.

  • Objectives : The aim of this study is to summarise pattern-identification of shoulder pain based on the classics of oriental medicine, current literature and domestic papers. Methods : The materials selected were sourced from the classics of oriental medicine, current literature and domestic papers which contained data related to pattern-identification of shoulder pain. The pattern-identifications were compared to determine the similarities, and these were classified. Results : Thirty-five studies were reviewed, and thirty-seven pattern-identifications were collated. These were classified into the following groups: wind-cold-dampness group(n = 8), blood stasis group(n = 3), phlegm group(n = 7), dual deficiency of Qi and blood group(n = 4), deficiency cold group(n = 2), liver-kidney deficiency group(n = 1) and meridian-collateral group(n = 12). Conclusions : On the basis of the classification of pattern-identifications, two groups of pattern-identifications for shoulder pain were suggested. The first group included the pattern-identification associated with a disease-cause, which included the wind-cold-dampness pattern(風寒濕型), blood stasis pattern(瘀血型), phlegm pattern(痰飮型), Qi-blood deficiency pattern(氣血兩虛型), deficiency cold pattern(虛寒型), and liver-kidney deficiency pattern(肝腎虧損型). The second included the pattern-identification associated with the meridian-collateral, which included the hand greater Yin meridian pattern(手太陰經型), hand Yang brightness meridian pattern(手陽明經型), hand lesser Yin meridian pattern(手少陰經型), hand greater Yang meridian pattern(手太陽經型), hand reverting Yin meridian pattern(手厥陰經型), hand lesser Yang meridian pattern(手少陽經型), and foot greater Yang meridian pattern(足太陽經型).

  • The present study aims to review the wave pattern resistance analysis method suggested by the International Towing Tank Conference. From the experimental database of a container carrier ship model, the wave pattern measurement and resistance test results are utilized. The wave pattern resistance at the design Froude number is obtained to be compared with the wave making resistance of experiments. Wave pattern resistance is lower than wave making resistance by 1978 ITTC and uniform regardless of transverse location of wave cut. The method is also applied to the wave height field by Computational Fluid Dynamics (CFD) analyses with Froude number variation. Although numerical damping suppressed waves in downstream, waves around the hull and wave pattern resistance are properly predicted.

  • The purpose of this study is to figure out the types and characteristics of the twill damask fabrics through literatures review of both domestic and Chinese documents and records. In addition, the study aims to review the characteristics of the twill damask fabrics found at Sukga Pagoda. The twill damask fabrics can be categorized in terms of the weaving method into Float Pattern on a Tabby Ground, Twill Pattern on a Tabby Ground, Float Pattern on a Twill Ground, Twill Pattern on a Twill Ground, and Without Pattern on a Twill Ground. The fabrics ran also be divided in terms of their name into Ki, Neung, and Munju. Four items of twill damask fabrics were found inside the Sukga Pagoda. All of them are Twill Pattern on a Twill Ground. At the primitive level of weaving skill, twill damask fabric was made by adding patterns with twill damask or BuJik on the background of plain weave. At more advanced level, the fabrics are weaved by making patterns with twill damask or BuJik on the background of twill damask. Compared to the relics of Koryo and Chosun Dynasty, these twill damask fabrics were loosely weaved with relatively thick thread.

  • The aim of this study was to explore the effects of a computerized review program which was introduced in August 1, 2003, using claims data for acute respiratory infection related diseases. National Health Insurance (NHI) claims data on respiratory infection related diseases before and after the introduction, with six month intervals respectively, were used for the analysis. Clinic was the unit of observation, and clinics with only one physician whose specialty was internal medicine, pediatrics, otorhinolaryngology and family medicine and clinics with a general practitioner were selected. The final sample had 7,637 clinics in total. Indices used to measure practice pattern was prescription rates of antibiotics, prescription rates of injection drug per visit, treatment costs per claim, and total costs per claim. Changes in the number of claims for major disease categories and upcoding index for disease categories were used to measure claiming behavior. Data were analysed using descriptive analysis, t-test for indices changes before and after the introduction, analysis of variance (ANOVA) for practice pattern change for major disease categories, and multiple regression analysis to identify whether new system influenced on provider' practice patterns or not. Prescription of antibiotics, prescription rates of injection drug, treatment costs per claim, and total costs per claim decreased significantly. Results from multiple regression analysis showed that a computerized review system had effects on all the indices measuring behavior. Introduction of the new system had the spillover effects on the provider's behavior in the related disease categories in addition to the effects in the target diseases, but the magnitude of the effects were bigger among the target diseases. Rates of claims for computerized review over total claims for respiratory diseases significantly decreased after the introduction of a computerized review system and rates of claims for non target diseases increased, which was also statistically significant. Distribution of the number of claims by disease categories after the introduction of a computerized review system changed so as to increase the costs per claims. Analysis of upcoding index showed index for 'other acute lower respiratory infection (J20-22)', which was included in the review target, decreased and 'otitis media (H65, H66)', which was not included in the review target, increase. Factors affecting provider's practice patterns should be taken into consideration when policies on claims review method and behavior changes. It is critical to include strategies to decrease the variations among providers.

  • Purpose: Unbalanced diets and decreased physical activity have contributed to increased prevalence of obesity and metabolic syndrome in adolescents. We have performed a systematic review and data analysis to examine the association between dietary pattern and metabolic syndrome risk factors in adolescents. Methods: We searched the PubMed and BioMedLib databases for appropriate articles published during the past 10 years and selected 6 articles. The studies reviewed applied factor analysis or cluster analysis to extract dietary patterns. For data analysis, we examined the association between dietary patterns and the prevalence of metabolic syndrome risk factors using data of 3,168 adolescents (13 to 18 years) obtained from 4 consecutive Korean Nutrition Health and Nutrition Examination Surveys (1998, 2001, 2005, and 2007 to 2009). Results: Our systematic review confirmed that western dietary patterns are positively associated with metabolic syndrome risk factors such as obesity and elevated triglycerides, while traditional dietary patterns were negatively associated. Data analysis found that the number of adolescents aged 16 to 18 years who had "Rice & Kimchi" dietary pattern decreased, while the number having western dietary patterns increased during the 1998 to 2009 time frame. There were no changes in the dietary patterns in adolescents aged 13 to 15 years. The risk of elevated serum triglycerides and reduced serum high density lipoprotein cholesterol was high in the "Rice & Kimchi" dietary pattern compared to the other dietary pattern groups. Conclusion: Because adolescents' dietary patterns are changing continuously and have long-term effects, further studies on the dietary patterns of adolescents and their health effects into adulthood are necessary.
