Objectives: Screening for second primary cancer (SPC) is one of the key components of cancer survivorship care. The aim of the present study was to explore oncologists' experience with promoting second primary cancer screening. Methods: Two focus group interviews were conducted with 12 oncologists of diverse backgrounds. Recurrent issues were identified and placed into thematic categories. Results: Most of the oncologists did not consider SPC screening promotion as their responsibility and did not cover it in routine care. All of the study participants had experience with unexpected SPC cases, and they were under emotional tress. There was no systematic manner of providing SPC screening. Oncologists usually prescribe SPC screening in response to patients' requests, and there was no active promotion of SPC screening. Short consultation time, limited knowledge about cancer screening, no established guideline for SPC screening, and disagreement with patients about oncologists' roles were major barriers to its promotion. An institution-based shared care model was suggested as a potential solution for promoting SPC screening given current oncology practices in Korea. Conclusion: Oncologists could not effectively deal with the occurrence of SPC, and they were not actively promoting SPC screening. Lack of knowledge, limited health care resources, and no established guidelines were major barriers for promoting SPC screening to cancer survivors. More active involvement of oncologists and a systematic approach such as shared-care models would be necessary for promoting SPC screening considering increasing number of cancer survivors who are vulnerable.

Background: The appropriate interval between negative colonoscopy screenings is uncertain, but the numbers of advanced neoplasms 10 years after a negative result are generally low. We aimed to evaluate the cost-effectiveness of colorectal neoplasm screening and management based on repeat screening colonoscopy every 10 years or single colonoscopy, compared with no screening in the general population. Methods and materials: A state-transition Markov model simulated 100,000 individuals aged 50-80 years accepting repeat screening colonoscopy every 10 years or single colonoscopy, offered to every subject. Colorectal adenomas found during colonoscopy were removed by polypectomy, and the subjects were followed with surveillance every three years. For subjects with a normal result, colonoscopy was resumed within ten years in the repeat screening strategy. In single screening strategy, screening process was terminated. Direct costs such as screening tests, cancer treatment and costs of complications were included. Indirect costs were excluded from the model. The incremental cost-effectiveness ratio was used to evaluate the cost-effectiveness of the different screening strategies. Results: Assuming a first-time compliance rate of 90%, repeat screening colonoscopy and single colonoscopy can reduce the incidence of colorectal cancer by 65.8% and 67.2% respectively. The incremental cost-effectiveness ratio for single colonoscopy (49 Renminbi Yuan [RMB]) was much lower than that for repeat screening colonoscopy (474 RMB). Single colonoscopy was a more cost-effective strategy, which was not sensitive to the compliance rate of colonoscopy and the cost of advanced colorectal cancer. Conclusion: Single colonoscopy is suggested to be the more cost-effective strategy for screening and management of colorectal neoplasms and may be recommended in China clinical practice.

This paper presents a new systematic contingency selection, screening and ranking method for on-line transient security assessment. Transient stability of a particular generator is influenced most by fault near it. Fault at the transmission lines adjacent to the generators are selected as contingency. Two screening methods are developed using the sensitivity of modal synchronizing torque coefficient and computing an approximate critical clearing time(CCT) without time simulation. The first method, which considers only synchronizing power, may mislead in some cases since it does not consider the acceleration power. The approximate CCT method, which consider both the acceleration and deceleration power, worked well. Finally the Single Machine Equivalent(SIME) method is implemented using IPLAN of PSS/E for detailed stability analysis.

Objectives: To review the status of newborn hearing screening (NHS) and to investigate the effect of the examiners on NHS tests to help the quality control of NHS at a general hospital in a city. Methods: The charts of newborns from January 2015 to March 2016 and from August 2016 to October 2017 were retrospectively reviewed. We compared the results of tests performed by several examiners(group 1) with those performed by one audiologist (group 2) using the same automated auditory brainstem response test. Results: The screening rate and referral rate were not significantly different between group 1 and group 2. The confirmatory test rate was higher in the group 2, but it was not significant. In group 1, the number of tests performed 3 or more times in one ear at one time was significantly higher. The number of tests performed in only one ear at one time was higher in group 2. The screening rate within one month after birth was 64.21%, referral rate was 7.32%, confirmatory test rate within 3 months after birth was 21.74%, and the prevalence of hearing loss was 1.46%. Conclusions: There was no significant difference of results depending on the examiners. In order to make proper screening test, it is necessary to periodically educate the examiner and to instruct the examiner by the supervisor doctors.

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.

Polyhydroxyalkanoate (PHA) synthase is a key enzyme for PHA production in microorganisms. The class IV PHA synthase is composed of two subunits: PhaC and PhaR. The PhaR subunit, which encodes the phaR gene, is only present in class IV PHA synthases. Therefore, the phaR gene is used as a biomarker for bacteria that contain a class IV PHA synthase, such as some Bacillus spp. The phaR gene was developed to screen phaR-containing Bacillus spp. The phaR screening method involved two steps: phaR gene amplification by PCR and phaR amplicon detection using a DNA lateral flow assay. The screening method has a high specificity for phaR-containing Bacillus spp. The lowest amount of genomic DNA of B. thuringiensis ATCC 10792 that the phaR screening method could detect was 10 pg. This novel screening method improves the specificity and sensitivity of phaR gene screening and reduces the time and cost of the screening process, which could enhance the opportunity to discover good candidate PHA producers. Nevertheless, the screening method can certainly be used as a tool to screen phaR-containing Bacillus spp. from environmental samples.
