Aims: The purpose of this study was to investigate the effects of a breast cancer screening educational program on women's knowledge and intention to seek breast cancer screening in Taiwan. Materials and Method: This study describes the knowledge and intention of breast cancer screening changes during the period pre and post group education. A pre-test and post-test were used in both the experimental and the control groups. A convenience sampling was used. Two structured questionnaires were used. Results: The mean knowledge of breast cancer screening scores (pre-test and post-test) of the experimental group participants were 12.6 and 14.0. Then the mean knowledge of breast cancer screening scores (pre-test and post-test) of the control group participants were 11.8 and 12.1. The mean intention of breast cancer screening scores (pre-test and post-test) of the experimental group participants were 11.4 and 13.5. And the mean intention of breast cancer screening scores (pre-test and post-test) of the control group participants were 11.6 and 12.4. An independent-t test was applied to examine the differences among the two groups, revealing that the average post-test knowledge score differ significantly between the two groups (t =4.18, p<.00); and the post-test intention also demonstrate a marked statistical difference (t = 2.07, p<.05). A paired-t test was applied to examine the differences of each group, revealing that the total average scores of the experimental group participants on the knowledge of breast cancer screening scale clearly differ statistically (t =-5.54, p<.00); and the pre-test and post-test intention testing also demonstrate a marked statistical difference (t =-7.70, p<.00). Conclusions: These findings are helpful in understanding the knowledge and intention of breast cancer screening changes during the period pre and post group education. It is expected that these results can offer a reference for clinical breast cancer prevention.

Introduction: Despite health education efforts to educate women on breast cancer and breast cancer screening modalities, the incidence of breast cancer and presentation at an advanced stage are still a problem in Malaysia. Objectives: To determine factors associated with the uptake of breast cancer screening among women in the general population. Methods: This pre-intervention survey was conducted in a suburban district. All households were approached and women aged 20 to 60 years old were interviewed with pre-tested guided questionnaires. Variables collected included socio-demographic characteristics, knowledge on breast cancer and screening practice of breast cancer. Univariate and multivariate analysis were performed. Results: 41.5% of a total of 381 respondents scored above average; the mean knowledge score on causes and risks factors of breast cancer was 3.41 out of 5 (SD1.609). 58.5% had ever practiced BSE with half of them performing it at regular monthly intervals. Uptake of CBE by nurses and by doctors was 40.7% and 37.3%, respectively. Mammogram uptake was 14.6%. Significant predictors of BSE were good knowledge of breast cancer (OR=2.654, 95% CI: 1.033-6.816), being married (OR=2.213, 95% CI: 1.201-4.076) and attending CBE (OR=1.729, 95% CI: 1.122-2.665). Significant predictors for CBE included being married (OR=2.161, 95% CI: 1.174-3.979), good knowledge of breast cancer (OR=2.286, 95% CI: 1.012-5.161), and social support for breast cancer screening (OR=2.312, 95% CI: 1.245-4.293). Women who had CBE were more likely to undergo mammographic screening of the breast (OR=5.744, 95% CI: 2.112-15.623), p<0.005. Conclusion: CBE attendance is a strong factor in promoting BSE and mammography, educating women on the importance of breast cancer screening and on how to conduct BSE. The currently opportunistic conduct of CBE should be extended to active calling of women for CBE.

한반도는 고도의 산업화와 도시화로 인해 깨끗한 MT 및 GDS 자료를 획득하기 매우 어렵다. 이러한 환경에서는 적당한 신호 대 잡음비를 가지는 자료를 선별하는 전처리 과정이 필수적이다. 본 연구에서는 전자기장의 분광에너지에 기반한 자동 전처리 과정(RMP)을 한반도의 현실적인 상황을 고려하여 수정하였고, 이를 한반도 내륙에서 획득된 총 7 측점의 MT 자료에 적용하였다. 전반적으로, RMP 기법은 주기 10초 대역 부근에서 주파수에 따른 전기비저항과 위상의 연결성을 상당히 향상시켰다. 또한 RMP 기법에 의한 결과는 수작업으로 편집된 기존의 처리 결과와도 거의 유사였고, 특히 전기 비저항의 연결성면에서 그 우수성이 확인되었다.

The purpose of this study was to evaluate whether screening by clinical breast examination (CBE) in addition to mammography affected participant satisfaction in the National Cancer Screening Program (NCSP). Data were derived from the Quality Evaluation of National Cancer Screening satisfaction survey. This population-based nationwide telephone survey included participants who had been screened by the NCSP for breast cancer between June and August 2010 (n=2,370), and collected information on satisfaction with screening and screening service use. Five multiple regression models were used to determine satisfaction according to screening method, and according to each of five satisfaction measures (pre-screening information transfer, staff interpersonal skills, physical surroundings, reporting of results and general satisfaction). A total of 1,858 (78.4%) participants were screened by mammography alone and 512 (21.6%) by both mammography and CBE. Satisfaction was significantly higher in subjects screened by both mammography and CBE compared with those screened by mammography alone.

Isothiazolinone derivatives are widely used in consumer products as disinfectants or preservatives, but there are growing concerns about their impact on human health. Therefore, rapid screening of these biocides is very important for proper control and regulation of potentially hazardous substances. To this end, low-temperature plasma (LTP) ionization mass spectrometry (MS) was investigated to demonstrate its potential for direct and selective analysis of isothiazolinones from sprayed aerosol samples. Benzisothiazolinone (BIT) was clearly identified from a commercial fabric deodorant using LTP ionization MS and MS/MS. LTP allowed selective ionization of BIT directly from the simply sprayed aerosol sample and illustrated its potential for fast screening without sample pre-treatments. Selective nature of LTP ionization, on the other hands, implicates use of LTP ionization MS as a general screening method for specific groups of hazardous chemicals in commercial products.

When assessing buildings that may collapse during a large earthquake, conventional rapid visual screening procedures generally provide good results when identifying buildings for further investigation. Unfortunately, their accuracy at identify buildings at risk is not so good. In addition, there appears to be little room for improvement. This paper investigates an alternative screening procedure based on fuzzy logic and artificial neural networks. Two databases of buildings damaged during the Athens earthquake of 1999 are used for training purposes. Extremely good results are obtained from one database and not so good results are obtained from the second database. This finding illustrates the importance of specifically collecting data tailored to the requirements of the fuzzy logic based rapid visual screening procedure. In general, results demonstrate that the trained fuzzy logic based rapid visual screening procedure represents a marked improvement when identifying buildings at risk. In particular, when smaller percentages of the buildings with high damage scores are extracted for further investigation, the proposed fuzzy screening procedure becomes more efficient. This paper shows that the proposed procedure has a significant optimisation potential, is worth pursuing and, to this end, a strategy that outlines the future development of the fuzzy logic based rapid visual screening procedure is proposed.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has significantly disrupted cancer screening services worldwide. We aimed to measure the impact of COVID-19 on gastric cancer screening rates based on age, sex, household income, and residential area. Materials and Methods: We analyzed data from the Korean National Cancer Screening Survey from 2017 to 2021 for adults aged 40-74 years. We evaluated the gastric cancer screening rate within two years in accordance with the National Cancer Screening Program protocol recommendations and that within the previous year. We compared the trends in the pre- and post-COVID-19 outbreak periods. Results: Before the COVID-19 outbreak, there was little change in the gastric cancer screening rates until 2019. After the COVID-19 outbreak, the screening rate as per recommendation decreased from 70.8% in 2019 to 68.9% in 2020 and that for one year decreased from 32.7% in 2019 to 27.2% in 2020. However, as the COVID-19 pandemic continued after 2020, both gastric cancer screening rates as per recommendations and for one year rebounded. Although a similar trend was observed for the upper endoscopy screening rate, the upper gastrointestinal series screening rate decreased from 7.8% in 2020 to 3.1% in 2021. During the pandemic, the screening rate decreased among younger adults (40-49), those residing in metropolitan regions, and those with high incomes. Conclusions: Despite a decline in gastric cancer screening rate during the COVID-19 pandemic, the rate surged in 2021. Further studies are needed to estimate the impact of cancer screening delays on future cancer-related mortalities.

Objectives: Recent studies have shown that tailored messages for cancer screening to the beliefs and stage of cancer screening behavior of individual women increases the take-up probability. Many studies on cancer screening have used the Transtheoretical Model (TTM) to identify variables associated with cancer screening behavior. This study was carried out to identify the cognitive-behavioral factors associated with stomach cancer screening among women aged 40 years and over, and to develop and evaluate a tailored educational program for stomach cancer screening by stages of change. Methods: Building on the TTM constructs, we conducted a quasi-experimental study(N=283) to test the effectiveness of a tailored educational program for endoscopic stomach cancer screening. We carried out pre and post tests in the experimental group(N=162) and the control group(N=121), and the experimental group was subdivided into an on-line group(N=81) and an off-line group(N=81) by educational methodology using e-mail and the postal service. We used the chi-square test, trend test, and paired t-test to test the effectiveness of the program for stomach cancer using a tailored stage-matched messages. Results: To examine the effectiveness of the program for stomach cancer screening by the tailored stage-matched messages, the stage-matched materials were offered to the experimental group(N=162) four times for 4 weeks. The stage-matched materials consisted of the four types for stomach cancer. The tailored message was effective in changing the cognitive-behavioral factors, such as experience process, behavior process, con opinion for stomach cancer, self-efficacy, and the behavioral stages for stomach cancer screening. The stomach cancer screening adherence was higher for the stage-matched materials using postal mail than for those using e-mail. Conclusion: To improve the stomach cancer screening rate, the use of tailored messages for stomach cancer screening will be generated using an expert system. Therefore the implementation of tailored educational program will be supported a partnership between public and private health organizations and increasing awareness of the necessity of community-based interventions.
