Owing to the rapid growth in automated manufacturing systems, screening inspection becomes an attractive practice for removing nonconforming items, and it has been suggested that inspection will essentially become an inherent part of modem manufacturing processes. In this paper, we propose rectifying screening inspections which allow quality practitioners to use performance and surrogate variables interchangeably in real-time applications. Two screening inspections are considered; a statistically-based screening inspection to reduce the current proportion of nonconforming items to a specified AOQ(average outgoing quality) after screening, and an economically-based screening inspection where the tolerance limit is determined so that the expected total cost is minimized. It is assumed that the performance variable and the surrogate variable are jointly normally distributed. For two screening inspections, methods of finding the optimal solutions are presented and numerical examples are also given.

Along with a development of medical technology, a variety of tests, such as laboratory tests, x-ray and endoscopies are being used in health screening tests. As the tests determine the quality of health screening, test items of major health screening program in Korea. Most, of the health screening programmes focused upon detection of risk factors and diagnosis of life-style related diseases(diabetes, hypertension, cardiovascular diseases, hypercholesterolemia, overweight, drinking, smoking, cerebrovascular diseases, osteoporosis), cancers(stomach, cervix, lung, breast, liver, colon, prostate, ovary, pancreas, thyroid, esophagus), infections diseases(hepatitis, tuberculosis, sexually-transmitted diseases, parasites), chronic obstructive respiratory diseases, chronic renal diseases(bacteriuria, hematuria, proteinuria), anemia, glaucoma, hearing loss, Alzheimer disease, stress and earlypsychiatric diseases. The health screening tests were basic physical examination, basic laboratory tests( CBC, urinalysis, liver function tests, lipid tests, glucose, HbA1c, uric acid, electrolytes, serological tests(HBsAg, HBs-Ab, HCV-Ab, HIV-Ab, VDRL) EKG, x-ray(chest PA, CT) endoscopy(gastroscopy, colonoscopy), sonography (abdomen, thyroid, pelvis, breast), cytology(cervix), bone density, tumor markers(NMP22, alpha-FP, CEA, CA-19-9, CA125, PSA and eye tests. Advanced technologies, like CT, PET, MRI, MRI/Angio, molecular testing were widly used in hospital based health screening programmes. In summary, a variety of tests were untilized in health screening in Korea. Those tests were utilized by stages or according to sex and age in most of health screening programmes, however a few programs used tests excessvely disregarding health screening subjects.

Objectives: This retrospective cohort study aimed to estimate the mean sojourn time (MST) of preclinical gastric cancer in Korean men. Methods: The subjects consisted of voluntary male screenees aged 40 to 69 years who underwent subsequent screening gastroscopies after testing negative at a baseline screening performed between January 2007 and December 2011. A new case was defined if gastric cancer cells were present in the biopsy specimens obtained from gastroscopy. The follow-up period was calculated as the number of person-years between the date of baseline screening gastroscopy and positive findings at a subsequent screening. The MST was calculated using transition rates of gastric cancer to determine the best screening interval. Results: Of the 171 979 voluntary male screenees, 61 688 (36%) underwent subsequent screening gastroscopies between January 2007 and December 2011. A total of 91 incident cases were found during 19 598 598 person-years of follow-up. The MST of gastric cancer was 2.37 years (95% confidence intervals, 1.92 to 2.96), and those aged 40 to 49 years had a shorter MST than those 50 to 69 years did. Conclusions: These findings support the 2-year interval of screening recommended by the nationwide gastric cancer screening program in Korea. Further studies for the age-specific MST among women are needed.

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.

Purpose: The aim of this study was to compare health promotion behavior in middle-aged rural residents by cancer screening participation. Methods: Data were collected from 508 rural residents during the period from April 6 to June 6, 2009 using structured questionnaires, and analyzed using SPSS/WIN 12.0. Results: The cancer screening rate was 50.2%. The rate was significantly different according to sex, educational level, marital status, private insurance, family cancer history, smoking, drinking, perceived health status, and health concern. Men showed the highest screening rate in gastroscopy for stomach cancer, and women in pap smear test for cervical cancer. Pap smear test for cervical cancer showed the highest regular screening rate (4.3%). The average score of health promotion behavior was $2.65{\pm}0.35$. Health promotion behavior was significantly different according to cancer screening participation, health responsibility, stress management, and self actualization. Conclusions: These results suggested that there may be differences in health promotion behavior among middle-aged rural residents according to their cancer screening participation. A further study is necessary to find effective interventions for the non-cancer screening group.

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).

Objective: Despite government efforts to increase participation in gastric cancer screening, the rate is still suboptimal in Korea. Therefore, we explored barriers to and predictors of gastric cancer screening participation among a nationally representative sample. Methods: We used the Health Interview Survey sub-dataset derived from the Fourth Korean National Health and Nutrition Examination Survey 2008 (KNHANES IV) to evaluate participation in gastric cancer screening and factors associated with attendance in individuals age ${\geq}40$ years. We enrolled 4,464 subjects who completed the questionnaire and were not previously diagnosed with gastric cancer. Four groups of factors were considered potential predictors of gastric cancer screening in a multivariate analysis: sociodemographic, health behavior, psychological and cognitive, and dietary factors. Results: Overall, 41.3% complied with the gastric cancer screening recommendations. Younger age, lower education level, living without a spouse, frequent binge drinker, and current smoker were significantly associated with less participation in gastric cancer screening. Conclusions: To improve participation in gastric cancer screening, more focused interventions should be directed to vulnerable populations, such as groups with low socioeconomic status or unhealthy behavior. In addition, there should be new promotional campaigns and health education to provide information targeting these vulnerable populations.

Cervical cancer, the third commonest cancer in women worldwide, can be prevented through early detection by cervical screening (Pap smear). The aim of this study was to investigate the attitudes and practice of cervical cancer screening among female undergraduate university students from 25 low, middle income and emerging economy countries. Using anonymous questionnaires, data were collected from 9,194 female undergraduate university students aged 18-26 years (mean age 20.9, SD=2.0) from 26 universities in 25 countries across Asia, Africa and the Americas. Overall, 11.6% of the female students indicated that they had conducted one or more times a cervical (Pap) smear test; 8.3% among 18-20 year-olds and 15.6% among 21-26 year-old students. There was considerable country variation on having had a cervical (Pap) smear test among 21-26 year-old female university students, ranging from 59.2% in Colombia and 50.9% in Barbados to 0% in India and 1.0% in Tunesia. Logistic regression showed that cervical cancer screening importance or positive attitude were highly associated with the cervical screening practice. Moreover, risky sexual behaviour and tobacco use, two cervical cancer risk factors, were associated with screening. Cervical cancer screening practices were found to be inadequate and e fforts should be made to develop programmes that can increase the uptake of cervical cancer screening.

Objectives: Breast cancer is a leading cause of morbidity and mortality in women worldwide. Breast screening in normal and/or asymptomatic women is essential to reduce the burden of breast malignancies. Our study aimed to identify possible risk- and/or co-factors associated with breast screening in North Indian women. Methods: A public health research survey was conducted among 100 women of North Indian ethnicity during clinic visits in a 6-month timeline (April-October 2012). Demographic and clinical data, including mammography screening, were recorded in the questionnaire-based proforma after conducting a 10 minute interview. Written informed consent was taken from all the participants. Results: The mean age of the participants was $32.2{\pm}9.9$ years. Out of 100 women, 6% had family history of breast disease. Breast-related complaints/malignancy, including galactorrhoea, mastitis, axillary lump, fibrocystic disease, fibroadenosis and adenocarcinoma were observed in 41% participants; age stratification revealed that 82.9% of this group (n=41) were <30 years, while 9.7% and 7.3% were >30 years and 30 years of age, respectively. 32% participants underwent mammography screening and 8% had breast ultrasound imaging. Age stratification in the mammography screening group demonstrated that 24 women were <40 years, while 7 women were >40 years. Conclusions: Our pilot study identified possible co-factors affecting breast screening in North Indian women. These findings may be beneficial in early detection of breast abnormalities, including malignancies in women susceptible to breast cancer, and thus aid in future design of cost-effective screening strategies to reduce the increasing burden of breast carcinoma in women worldwide.

Purpose: This study was conducted to survey the cancer screening status of Korean elderly and to analyze factors influencing cancer rescreening intention. Methods: Participants were 262 elderly aged 65 or older who visited medical examination center at D University hospital located in D city. Data were collected from June 1 to July 31, 2012 using a structured questionnaire which included health behavior and cancer screening related characteristics, theory of planned behavior variables, EQ-5D, and cancer screening satisfaction. The data were analyzed by SPSS/WIN 18.0 program. Results: Factors influencing elderly's cancer rescreening intention were 'satisfaction about the cancer screening', 'attitude toward cancer rescreening behavior', 'subjective norm toward cancer rescreening behavior', and 'previous experience with cancer screening in the past 2 years'. Cancer rescreening intention was higher in participants with satisfied experience of cancer screening, more positive in attitude and higher in subjective norm toward cancer rescreening. Cancer rescreening intention was lower when participants were not screened for cancer in the past 2 years. Conclusion: The study results indicate that customized interventions based on influential factors such as subjective norm, attitude toward cancer screening, and cancer screening satisfaction are necessary in order to promote the consistent cancer screening of Korean elderly.
