  • This study was aimed at preparing basic data required for establishment of a cancer screening program by examining the status of cancer screenings performed by women in a city and the factors that had an influence on cervical and breast cancers screening behavior of women. In order to find out the status of cervical and breast cancers screening and the factors having an influence on cervical and breast cancers screening behavior, 1,113 women were selected as study area and subjects by a random cluster sampling method, and the subjects were answered by questionnaires. The major results were as follows: 1. In the cases of the breast and the cervical cancers, 16.7% and 55.7% of the subjects turned out to have had one or more screenings respectively in their life-time. Also the rate of screening group of cervical and breast cancers was 16.7%, the rate of screening group of only cervical cancer was 38.9%, and the rate of non-screening group was 44.4%. 2. As to the screening pattern of cervical and breast cancer, there were significantly for age, income, occupation, married status, spouse, the factors associated with health promotion (doctor visiting, exercising), married age, number of children, and breast feeding(p〈0.05). 3. The factors associated with screening behaviors for cervical and breast cancers were age, income, occupation, married status, doctor visiting, exercising, married age, number of children, and breast feeding(p〈0.05). Based on the above-mentioned results obtained by this study, it was anticipated that this study may be playa vital role as basic data for the development and execution of cervical and breast cancers screening program for women in a community. And the analysis, done on the basis of the status of the cancer screening, of the influence factors on cervical and breast cancers screening behavior showed that for the development of a cancer screening program, the factors like age, social-economic class, married status, health promotion behavior, and reproductive characteristics should be considered.

  • Chorionic villus sampling has gained importance as a tool for early cytogenetic diagnosis with a shift toward first trimester screening. First trimester screening using nuchal translucency and biomarkers is effective for screening. Chorionic villus sampling generally is performed at 10-12 weeks by either the transcervical or transabdominal approach. There are two methods of analysis; the direct method and the culture method. While the direct method may prevent maternal cell contamination, the culture method may be more representative of the true fetal karyotype. There is a concern for mosaicism which occurs in approximately 1% of cases, and mosaic results require genetic counseling and follow-up amniocentesis or fetal blood sampling. In terms of complications, procedure-related pregnancy loss rates may be the same as those for amniocentesis when undertaken in experienced centers. When the procedure is performed after 9 weeks gestation, the risk of limb reduction is not greater than the risk in the general population. At present, chorionic villus sampling is the gold standard method for early fetal karyotyping; however, we anticipate that improvements in noninvasive prenatal testing methods, such as cell free fetal DNA testing, will reduce the need for invasive procedures in the near future.

  • 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.

  • Background: In order to increase breast and cervical cancer screening uptake in Singapore, women's perceived barriers to screening need to be identified and overcome. Using data from both focus groups and surveys, we aimed to assess perceived barriers and motivations for breast and cervical cancer screening. Materials and Methods: We conducted 8 focus groups with 64 women, using thematic analysis to identify overarching themes related to women's attitudes towards screening. Based on recurring themes from focus groups, several hypotheses regarding potential barriers and motivations to screen were generated and tested through a national survey of 801 women aged 25-64. Results: Focus group participants had misconceptions related to screening, believing that the procedures were painful. Cost was an issue, as well as efficacy and fatalism. Conclusions: By identifying barriers to and motivators for screening through a mixed-method design that has both nuance and external validity, this study offers valuable suggestions to policymakers to improve breast and cervical cancer screening uptake in Singapore.

  • A cross-sectional survey of 370 female teachers working at Governmental schools in Gaza city was conducted. Twenty four schools were selected randomly of all female schools of the city that included primary, preparatory and secondary. In each school all-female teachers aged 35-45 year were invited to fill out a self-administered questionnaire to investigate knowledge and behavior toward breast cancer screening. The survey revealed that more than 75% of women had never undergone clinical breast examination and 60% had never undergone mammography, whereas 62% performed breast self-examination (BSE). Women who performed BSE had significantly higher knowledge about breast cancer screening (P=0.001). Women attending CBE and mammography screening also had significantly higher knowledge (P=0.001). There were significant associations between the practices and presence of positive breast cancer family history (P=0.002) and the level of education of husbands (P=0.024). The oldest women demonstrated higher performance rates of screening methods than the youngest (P=0.001). Lack of breast screening knowledge was identified among more than one third of the women, and 24.6% of women did not know any screening method. About a half of women harboured misconceptions about breast cancer screening, including the belief that breast cancer not treatable. Women residing in Gaza city (P=0.00) and with husbands less educated were more likely to have a high level of misconceptions (P=0.01).

  • This study, performed to analyze the factors associated with health and cancer screening using preventive programs form health insurance among the women of a community, through a survey of about 923 women in Euijungbu-city. The subjects of the study were selected by a proportional cluster sampling method. The self-reported questionnaire was intended to fine factors associated with health screening and cancer screening. The results of this study were as follows: 1. In the case of health screening using health insurance, 14.1% of the subjects turned out to have been screened once or more in their respective life-time. Reasons given for non-participation in the screening were : 'lacking screening information', a belief that' it's not useful' and a belief that they' weren't sick'. 2. The factors associated with health screening behavior were age, educational level, number of doctor visits, BMI and health promotion behavior(p<0.01, p<0.05). Also, the factors associated with health screening behavior were cue to action and health status, and the predictors on health screening behavior were age and health promotion behavior(p<0.01, p<0.05). 3. In the case of cancer screening through the health insurance, 7.4% of the subjects turned out to have been screened once or more respectively in their life-times. Reasons given for non-participation in the screening were : 'lacking screening information', a belief they 'weren't sick' and that it's not useful'. 4. The factors associated with cancer screening behavior were age, educational level, income, alcholol intake, exercise, number of doctor visits and BMI(p<0.01, p<0.05). Aditional factors associated with cancer screening behavior were cue to action, health belief score and health status. Predictors for cancer screening behavior were: age, health belief score, screening attitude and health status(p<0.01, p<0.05). As indicated by the above results, a lack of information was an important factor for a lack of participation in screening. Age and cue to action were also important factors in promoting the cancer screening rate. Therefore, a dissemination of information about cancer screening contributes to the promotion of a screening rate, and cooperation between health insurance and local health cancer facilitates to be public the community-based cancer screening program.

  • Purpose: A sensitive gas chromatography mass spectrometry (GC-MS) method was developed for screening of fatty acid oxidation disorders. Methods: The assay utilized a simple protein precipitation with sulfosalicylic acid followed by tert-butyl dimethylsilyl (TBDMS) derivatization of hydroxyl functional group by N-tert-butyldimethylsilyl-N-methyltrifluoroacetamide (MTBSTFA). Results: Calibration curves of spiked pooled plasma showed a linear relationship in the range of 0.01 ng -2 mg with correlation coefficient value greater than 0.98. Limits of detection (LOD) and limits of quantification (LOQ) were found in the range of 0.9-8.8 ng and 9-88 ng, respectively. Conclusion: The new developed method might be useful for a rapid, sensitive screening of inherited fatty acid oxidation disorders. In addition, the method expected to be one of the alternative method for screening newborns of metabolic disorders in the laboratories where expensive MS/MS is unavailable.

  • Like that mentioned in the 2nd report, because of panel's sense of psychological and physiological responsibility caused by multi-samples, great errors in experimental results are expected. So as to cut down these errors, the new method called "Pair Comparision with Standard" that reduces test frequency and is superior in detecting power is designed, and its mathematical model is proposed. This paper suggests that this method can be used for screening test that, first of all, selects 4-5 of multi-samples and the most efficient sensory evaluation method in laboratorial quality study is that, after screening by this method, Trio Paired Comparison for the final justification is applicated.

  • Effect of high voltage screening was examined on mechanical strength of titania ceramics with two different surface roughness. Roughly finished sample showed degraded mechanical strength meaning that the introduced flaw played the role of starting point of mechanical fracture. On such sample, electrically weak parts were eliminated by applying a screening field. Mechanical strength measurement on survived parts revealed that after screening the Weibull plots bended to become a convex curve while plots at high strength region were almost the same. This result means that relatively low mechanical strength parts were eliminated by the electrical method. As a result the Weibull modulus calculated from all the data increased, demonstrating the effect of high voltage screening on titania ceramics containing fracture controlling surface flaws. Roles of the surface flaw such as a common weak spot for both failures are disscussed in relation to the electric field concentration similar to that of mechanical stress.

  • In increasing the safety and usage of lithium-ion battery packs, reducing the parameter deviation between cells, such as voltage and temperature within the battery pack, is important. In this study, we propose a screening method to reduce parameter deviation between cells in battery packs. Screening algorithms are constructed based on Fuzzy logic and quantitatively express the similarities between battery cells. Screening is applied by utilizing series resistance components after experiments of electrical characteristics that consider the operation status of battery packs. After screening, the standard deviation of series resistance components according to the similarity ranking is compared and analyzed, and their conformity are verified with the algorithm parameters.
