Background and Objectives: Data on associations between soy food intake after cancer diagnosis with breast cancer survival are conflicting, so we conducted this meta-analysis for more accurate evaluation. Methods: Comprehensive searches were conducted to find cohort studies of the relationship between soy food intake after cancer diagnosis and breast cancer survival. Data were analyzed with comprehensive meta-analysis software. Results: Five cohort studies (11,206 patients) were included. Pooling all comparisons, soy food intake after diagnosis was associated with reduced mortality (HR 0.85, 95%CI 0.77 0.93) and recurrence (HR 0.79, 95%CI 0.72 0.87). Pooling the comparisons of highest vs. lowest dose, soy food intake after diagnosis was again associated with reduced mortality (HR 0.84, 95%CI 0.71 0.99) and recurrence (HR 0.74, 95%CI 0.64 0.85). Subgroup analysis of ER status showed that soy food intake was associated with reduced mortality in both ER negative (highest vs. lowest: HR 0.75, 95%CI 0.64 0.88) and ER positive patients (highest vs. lowest: HR 0.72, 95%CI 0.61 0.84), and both premenopausal (highest vs. lowest: HR 0.78, 95%CI 0.69 0.88) and postmenopausal patients (highest vs. lowest: HR 0.81, 95%CI 0.73 0.91). In additioin, soy food intake was associated with reduced recurrence in ER negative (highest vs. lowest: HR 0.64, 95%CI 0.44 0.94) and ER+/PR+ (highest vs. lowest: HR 0.65, 95%CI 0.49 0.86), and postmenopausal patients (highest vs. lowest: HR 0.67, 95%CI 0.56 0.80). Conclusion: Our meta-analysis showed that soy food intake might be associated with better survival, especially for ER negative, ER+/PR+, and postmenopausal patients.

Purpose: This study was done to identify the distribution and related factors for stage of change for wearing hearing protection devices (HPDs) by workers in environments with high noise. Predictors of Use of Hearing Protection Model and Trans-theoretical Model were tested. Methods: The participants were 755 workers from 20 noisy work places in Busan and Gyeongnam. Data were collected from January to April 2008 using self-administered questionnaires, and analyzed using multiple logistic regression. Results: There were significant differences in social mode (OR=1.35, 95% CI: 1.06-1.73) between precontemplation/contemplation and preparation stage, in males (OR=2.36, 95% CI: 1.24-4.51), workers with high school education or less (OR=1.39, 95% CI: 1.28-2.78), shift workers (OR=1.50, 95% CI: 1.02-2.21), workers who previously worked in noisy places (OR=1.39, 95% CI: 1.20-2.34), and workers who had previous hearing examinations (OR=1.89, 95% CI: 1.25-2.85), in the social model (OR=1.59, 95% CI: 1.42-1.78), and self-efficacy (OR=1.05, 95% CI: 1.02-1.08) between workers in preparation and action stages, in length of time working in noisy work places (OR=2.26, 95% CI: 1.17-4.39), social model (OR=1.66, 95% CI: 1.33-2.08), and perceived benefit (OR=0.95, 95% CI: 0.93-0.97) between action and maintenance stage. Conclusion: Social model was a common factor showing differences between two adjacent stages for wearing HPDs. The results provide data for developing programs to encourage workers to wear HPDs and application of these programs in work settings.

Objectives: The purpose of the study was to find determinants for participation in the National health screening program participation according to sex in Korean. Methods: Data for 5,355 from the Korea National Health and Nutrition Examination Survey VI was included. Impact factors were analyzed by sex using logistic regression. Results: The participation in men rates(65.6%) higher than women(60.6%). In the case of men, those who have higher age (OR=0.33, 95% CI 0.21-0.52), higher income(OR=0.72, 95% CI 0.54-0.97), higher education (OR=0.54, 95% CI 0.36-0.81), occupation(OR=1.80, 95% CI 1.38-2.36), spouse(OR=1.95, 95% CI 1.45-2.62) were shown to have health examination more frequently. In the case of women, those who live in more developed city(OR=1.42, 95% CI 1.1-1.76), have higher age(OR=0.17, 95% CI 0.11-0.26), higher income(OR=0.17, 95% CI 0.11-0.26), higher education(OR=0.68, CI 0.46-0.99), occupation(OR=1.54, CI 1.32-1.80) and health insurance(OR=2.68, 95% CI 1.17-6-15) were shown to have health examination more frequently insurance were shown to have health examination more frequently. Conclusions: As a result, for both, age, income, education and occupation influenced health examination rate. Additionally, for men, marital status and for women, residence and the type of their health insurance was influenced. Individualized intervention is needed to increase participation rate.

Purpose: The cephalic index (CI) is used to classify the head and every race has its unique characteristics. Previous studies published in Korea were limited to demonstrating the periodical change of the CI. This study was done to determine the CI change in 0 to 20 year-old Koreans by sex and age. Methods: The measurement was done on 1,222 Koreans ranging from 0 to 20 years of age, randomly selected from 2,156 who were diagnosed with simple concussion, had no other diseases or anomalies, and took cephalographs from January, 2000 to July, 2008. The files were obtained from $Marosis^{(R)}$ and then photogrammetry was done by $Photoshop^{(R)}$. To standardize the cephalograph, the Frankfort horizontal line was selected as the reference line on lateral view and the line connecting both lateral-orbitales on AP view. The maximal length was obtained from the lateral cephalograph and the maximal breadth from the AP cephalograph. Results: The CI showed no difference by sex (p=0.4848). The CI and age showed negative correlation (p<0.0001). Analyzed separately by the male and the female, the CI showed statistical significance in the male (p<0.0001), but not in the female (p=0.4741) group. Comparing the CI above the age of 11, the CI of the female became greater than that of the male. Conclusion: This study contributes to the standardization of CI measurement and the authors were able to obtain the average CI by age. We concluded that the CI decreased according to age and most Koreans belonged to barchycephalic or hyperbrachycephalic.

In this paper a CI(carrier interferometry) chip waveform shaping scheme which Is made up of orthogonal carriers equally spaced in frequency, and used to introduce frequency diversity benefits into DS-CDMA, is considered. A new communication scheme referred to as CI/DS-CDMA using CI chip shaping, is introduced. Through the performance evaluation of CI/DS-CDMA systems in a typical frequency selective fading channel environment, it is shown that the frequency diversity benefits of this system results in significant performance enhancements relative to traditional DS-COMA with RAKE receivers using the path diversity.

DS-COMA is now a matured multiple access technology that utilizes spreading codes for user separation. In this paper, we attempt to improve the performance of a multiuser DS-COMA system with a unique chip shaping code called Carrier Interferometry (CI) code. The CI codes exhibit an excellent correlation property that can be used in many applications. In DS-COMA with CI codes (CI/DS-COMA), the symbols are spread by a spreading code and then the chip signals are shaped using a CI code. Due to the correlation property of the CI code, a diversity gain from the shaped chip signals is achieved and the performance of DS-COMA is significantly improved. Comparison study demonstrates that the DS-COMA with CI outperforms the conventional DS-COMA system in multiuser environments.

Background: The unmet healthcare needs (UHNs) of people with disabilities (PWD) are not only detrimental to their quality of life but also can lead to serious health outcomes including death. A variety of factors including socioeconomic, personal, and environmental factors affect UHNs for PWD. Previous studies focused on individual socioeconomic and disability characteristics as influencing factors. Our studies included environmental factors that have a significant impact on the use of healthcare service by PWD. Methods: We analyzed the UHNs status and influencing factors among 4,326 adults with disabilities using the Korea Disability Life Data. Chisquare analysis identified differences in UHNs by general, disability, and environmental characteristics. Logistic regression determined factors affecting UHNs. Results: Those with low educational level (adjusted odds ratio [aOR], 1.229; 95% confidence interval [CI], 1.024-1.475), those with low income level (aOR, 1.416; 95% CI, 1.015-1.976), those who enrolled in private insurance (aOR, 1.234; 95% CI, 1.018-1.496), those who need help with daily living (aOR, 1.298; 95% CI, 1.059-1.592), those who did not go out (OR, 1.566; 95% CI, 1.274-1.924), those who use taxis (aOR, 1.407; 95% CI, 1.047-1.891) or call taxi for people with disabilities when going to the hospital (aOR, 1.370; 95% CI, 1.001-1.875), the communication disabled (aOR, 1.304; 95% CI, 1.029-1.651), those with poor subjective health status (aOR, 1.248; 95% CI, 1.043-1.494), those who felt the explanation of treatment results was insufficient (aOR, 4.035; 95% CI, 1.365-11.927), hose dissatisfied with healthcare services (aOR, 3.515; 95% CI, 2.741-4.508) were more likely to experience UHNs. Conclusion: Effective healthcare service provision for PWD requires not only financial assistance but also social support, along with education for healthcare staff, policies that consider the characteristics of disabilities.

Comparing the uses of '-canh-' with the ones of '-ci,'this study suggests that different modal interpretat ions by '-canh-' and '-ci' is based on the interpersonal relationship between speaker and interlocutor. While noting that '-canh-' and '-ci' are the modal indicators denoting degrees of speaker commitment, for making clear the illocutionary force of utterances, it is observed and explained that what the speaker is committed respectively by using '-canh-' and '-ci' is highly sensitive to the relativity of the known/unknown status of the informal ion introduced into discourse contexts .

Background: For decades, studies have been performed to evaluate the association between ABO blood groups and risk of cancer. However, whether ABO blood groups are associated with overall cancer risk remains unclear. We therefore conducted a meta-analysis of observational studies to assess this association. Materials and Methods: A search of Pubmed, Embase, ScienceDirect, Wiley, and Web of Knowledge databases (to May 2013) was supplemented by manual searches of bibliographies of key retrieved articles and relevant reviews. We included case-control studies and cohort studies with more than 100 cancer cases. Results: The search yielded 89 eligible studies that reported 100,554 cases at 30 cancer sites. For overall cancer risk, the pooled OR was 1.12 (95%CI: 1.09-1.16) for A vs. non- A groups, and 0.84 (95%CI: 0.80-0.88) for O vs. non-O groups. For individual cancer sites, blood group A was found to confer increased risk of gastric cancer (OR=1.18; 95%CI: 1.13-1.24), pancreatic cancer (OR=1.23; 95%CI: 1.15-1.32), breast cancer (OR=1.12; 95%CI: 1.01-1.24), ovarian cancer (OR=1.16; 95%CI: 1.04-1.27), and nasopharyngeal cancer (OR=1.17; 95%CI: 1.00-1.33). Blood group O was found to be linked to decreased risk of gastric cancer (OR=0.84; 95%CI: 0.80-0.88), pancreatic cancer (OR=0.75; 95%CI: 0.70-0.80), breast cancer (OR=0.90; 95%CI: 0.85-0.95), colorectal cancer (OR=0.89; 95%CI: 0.81-0.96), ovarian cancer (OR=0.76; 95%CI: 0.53-1.00), esophagus cancer (OR=0.94; 95%CI: 0.89-1.00), and nasopharyngeal cancer (OR=0.81; 95%CI: 0.70-0.91). Conclusions: Blood group A is associated with increased risk of cancer, and blood group O is associated with decreased risk of cancer.
