Purpose: This study was done to investigate the relationship between knowledge, attitude, and practice toward breast self-examination (BSE) among middle and high school girls. Methods: A cross-sectional descriptive study was conducted using self-report questionnaires. Participants were 412 students, 137 middle and 275 high school girls. Data were collected from December 7 to 23, 2016 and analyzed using t-test and Spearman correlation coefficient. Results: The percentage of correct answers for knowledge about breast self-examination among middle and high school girls was 29.2%. The mean score for practice ($5.89{\pm}0.10$) among middle and high school girls was low. For knowledge, there were significant differences according to grade (t=5.93, p<.001), having heard about BSE (t=4.02, p<.001), experience of BSE (t=2.51, p=.012), and need for education (t=3.37, p=.001). In practice, there were significant differences according to having heard about BSE (t=3.64, p<.001), experience of BSE (t=2.64, p=.017). Knowledge level of BSE positively correlated with practice of BSE (r=.21, p<.001). Conclusion: Research results suggest that education on BSE for middle and high school girls is needed to increase the possibility of early detection of breast cancer.

When new weapons are introduced, the target points estimation is one of the important objectives in the flight test as well as the safe separation. The prediction methods help to design the flight test schedule. However, the incremental aerodynamic coefficients in the aircraft flow field so-called BSE are difficult to predict. Generally, the semiempirical methods such as the grid methods, IFM and Flow TGP using database are used for estimation of BSE. However, these methods are quasi-steady methods using static aerodynamic loads. Nowadays the time-accurate CFD method is often used to predict the store separation event. In the current process, the incremental aerodynamic coefficients in BSE regime are calculated directly, and the elimination of delta coefficients is checked simultaneously. This stage can be used for the initial condition of Flow TGP with freestream database. Two dimensional supersonic and subsonic store separation problems have been simulated and incremental coefficients are calculated. The results show the time when the store gets out of BSE region.

Brassica oleracea var. italica (broccoli) is a type of cabbage that contains vitamins, minerals, and phytochemicals. Consequently, it is used as a potential nutraceutical source for improving human health by reducing oxidative stress and inflammatory responses. Here, the effects of broccoli sprout extract (BSE) on the inflammatory response were investigated through lipopolysaccharide (LPS)-induced inflammatory mouse models. First, we found that the BSE obviously reduce NO production in RAW 264.7 cells in response to LPS stimulation in in vitro study. Pretreatment with BSE administration improved sperm motility and testicular cell survivability in LPS-induced endotoxemic mice. Additionally, BSE treatment decreased the levels of the pro-inflammatory cytokines TNF-a, IL-1β, and IL-6, and COX-2 in testis of LPS-induced endotoxemic mice models. In conclusion, BSE could be a potential nutraceutical for preventing the excessive immune related infertility.

Purpose: The purpose of this study was to identify the current status of the awareness and practice of breast self-examination (BSE) among Korean women. Materials and Methods: The study population was derived from the 2007 Korea National Cancer Screening Survey (KNCSS), an annual cross-sectional survey that uses a nationally representative random sample to investigate cancer-screening rates and related factors. A total of 1,255 Korean women aged ${\geq}30$ years participated in this study. Results: Of all participants, 88.0% reported that they had heard of BSE. The most common source of information on BSE was the media such as TV, radio and newspapers (87.0%). Recommendations from medical staff reached only 17.2%. The overall proportions of regular and irregular BSE were 13.2% and 16.1%, respectively. The main reason for not performing BSE was lack of knowledge about how to conduct the exam (31.7%). Conclusion: Despite a high level of awareness about BSE, only a small minority of women examine their breasts regularly in Korea.

Processing of Scanning electron microscope imaging has been analyzed in both secondary electron (SE) imaging and backscattered electron (BSE) image. Because of unique characteristics of both secondary electron and backscattered electron image, mechanism of imaging process and image quality are quite different each other. For the sake of characterize imaging process, Monte Carlo simulation code have been developed. It simulates electron penetration and depth profile in certain material. In addition, secondary electron and backscattered electron generation process as well as their spatial distribution and energy characteristics can be simulated. Geometries that has fundamental feature have been imaged using the developed Monte Carlo code. Two, SE and BSE images generation process will be discussed. BSE imaging process can be readily used to discriminate in both material and geometry by simply changing position and direction of BSE detector. The developed MC code could be useful to design BSE detector and their position. Furthermore, surface reconstruction technique is possibly developed at the further research efforts. Basics of Monte Carlo simulation method will be discussed as well as characteristics of SE and BSE images.

Purpose: The aim of this study was to analyze breast cancer screening behaviors in working women. Method: A total of 354 women over 20 years of age were recruited from three major occupational settings by convenience sampling. The Champion's Health Beliefs Model Scale-Korean version and a structured questionnaire for measuring regularity and accuracy of breast self-examination(BSE) were used. Data were analyzed using descriptive statistics, $x^$-test, ANOVA, and Duncan post hoc tests. Result: Women who have performed BSE and had both BSE and clinical tests were 49.2% and 32.8%, respectively, while 36.7% of the participants had none of the screening. The screening patterns were significantly different by individual characteristics of age, occupation, experiences of breast disease, education at workplace, and by the level of confidence in health beliefs (p<.01, p<.05). Only 4 % of women performed BSE regularly and the level of accuracy of the BSE was very low as well. Conclusion: Education at the workplace needs to emphasize the recommended guidelines and further increase the quality and results of the BSE for women's health.

Background: Breast cancer is a serious health problem. Early detection is crucial for optimal treatment and reducing mortality. Objective: The aim of this study was to evaluate health beliefs concerning performance of breast self- examination (BSE) and mammography in a sample of Iranian female health workers. Materials and Methods: This cross-sectional study was performed among 441 female health care workers (physicians=88, nurses=163, midwives=38, officers=68, and others=84) in 3 different health centers in Yazd, Iran. Data were collected using a self administered questionnaire which included demographic characteristics and thenPersian version of the Champion's Health Belief Model Scale (CHBMS). Results: The mean age of the participants was $34.7{\pm}13.7$. It was found that 41.9% of the workers performed BSE in the past and 14.9% of them regularly, but only 10.6% of them had undergone a mammogram. Perceived barriers to BSE (F=6.351, P=0.021) and mammography (F=5.214, p=0.022) were significantly higher in officers than physicians, nurses or midwives. Perceived barriers were lower among those who had performed BSE and mammography, but not significant (p=0.34 and p=0.56, respectively). Furthermore, perceived susceptibility and perceived benefits of the workers who had BSE and mammography were significantly higher than who did not (p<0.05). Perceived seriousness was not a significant variable in BSE and mammography (p=0.71 and p=0.43, respectively). Conclusions: The health beliefs of health workers concerning the perceived susceptibility of breast cancer and the perceived benefits BSE and mammography significantly impact their screening practices.

Purpose: This study aims to identify differences in breast self-examination (BSE) performance and influencing factors between woman-groups under and over 45 years old. Methods: The subjects were 152 women aged from 35 to 65, who were recruited through convenient sampling in a metropolitan city. They were divided into two groups: under and over 45 years old. The data were collected using self-reporting questionnaires and analyzed by $x^2$ test, t-test, Pearson's correlation coefficient, and stepwise multiple regression. Results: Experience of BSE education ($x^2$=4.68, p=.030), BSE performance ($x^2$=20.12, p<.001), confidence (t=-2.97, p=.003), and self-efficacy (t=-2.44, p=.016) were significantly higher in the group over 45 years (the older group) than the one under 45 years (the younger group). Self-efficacy (${\beta}$=.346, p=.004) and susceptibility (${\beta}$=.238, p=.002) were 17.6% of the variance in the younger group's BSE performance. On the other hand, significantly influencing factors on the older group's BSE performance were self-efficacy (${\beta}$=.500, p<.001) and BSE education (${\beta}$=.217, p<.001), which accounted for 25% of the variance in the BSE performance. Conclusion: We conclude that differentiated strategies of considering age should be established in nursing intervention to detect breast cancer early.

Background: In Malaysia, breast cancer is the first cancer among females regardness of race. Aim: The purpose of this study was to identify the knowledge and BSE practice among undergraduate female students at four public universities in Klang Valley, Malaysia. Materials and Methods: This cross-sectional study was conducted among 820 undergraduate female students using a self-administered questionnaire covering socio-demographic data, knowledge of breast cancer and BSE practice. Results: The mean age of the respondents was $21.7{\pm}1.2$ years. The majority of them were single (96.8%), Malay (91.9%) and 16.5% of respondents had a family history of breast cancer. This study showed low level of knowledge on breast cancer and breast self-examination among participants. Only 19.6% participants were performing BSE regularly. Knowledge of breast self-examination was significantly associated with BSE practice (p=0.00). Also, there were significant associations between performing BSE with age, marital status and being trained by a doctor for doing BSE (p<0.05). Conclusions: Our findings showed that the rate of BSE practice and knowledge of breast cancer is inadequate among young Malaysian females. A public health education program is essential to improve breast cancer prevention among this group.
