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.

Objectives: This study aims to assess the stages of individual readiness to take the cancer screening test and to identify factors relating to the progress of their readiness to take the test. Methods: We analyzed the data acquired from our 'Cancer Screening Behavior among Korean Adults' Survey' in 2003. 1,057 participants' stages of readiness to take the cancer screening test were classified through the Precaution Adoption Process Model (PAPM). Their knowledge, beliefs and other factors related to cancer screening were examined at each PAPM stage through the Health Belief Model (HBM), and the various PAPM stages were compared with each other to identify factors likely to determine progress between stages. Results: The distribution of the PAPM stages of readiness for cancer screening was as follows: 18.9% were unaware; 9.7% were unengaged; 29.8% were deciding to take the test; 1.5% decided not to take the test; 11.6% decided to take the test, while 28.6% had taken the test. The factors likely to determine progress from one to another stage were 'Knowledge', 'Perceived susceptibility', 'Perceived benefits', 'Perceived barriers' and 'Family member's experience of cancer screening'. Conclusions: This study can be used to develop health promotion programs that enhance cancer screening behavior in Korea.

A three-step screening process is presented in this article for selection of consistent earthquake records in which number of suitable ground motions is quickly screened and reduced to a handful number. Records that remain at the end of this screening process considerably reduce the dispersion of structural responses. Then, an effective method is presented for spectral matching and modification of the selected records. Dispersion of structural responses is explored using different statistical measures for each scaling procedure. It is shown that the Uniform Design Method, presented in this study for scaling of earthquake records, results in most cases in the least dispersion measure.

Toner particles used in laser and xerographic printing process is fused on paper surface so strongly that they tend not to detach easily from the recylced paper surface during pulping. Furthermore, the removal efficiency of detached toner particles by conventional screening and flotation process has limitation due to the platy shape and large size of detached toner particles. It has been shown that the removal efficiency of toners in the screening process can be increased by agglomerating the toner particles with fatty alcohol. It is not possible, however, to remove small and platy toner particles by screening process. These small and platy toner particles should be removed by flotation process. In this study the effect of fatty alcohol that used for toner agglomeration on flotation efficiency has been examined. It was shown that flotation efficiency decreased when fatty alcohol was used most probably due to its effect of reducing hydrophobicity of toner particles.

Objectives: The aim of this study was to determine the distribution of stages of adoption in stomach cancer screening and elucidate differences among stages. Methods: A randomly selected sample of 712 Korean males and females aged 40 years or over were interviewed. Stomach cancer screening intention and behavior, sociodemographic characteristics, beliefs, self-efficacy and reinforcing characteristics were assessed. Results: The majority of participants were not on-schedule screening(unaware 3.2%, unengaged 20.8%, deciding about acting 24.0%, decided not to act 9.6%, decided to act 14.5%, acting 9.7%, maintenance 18.3%). Perceived susceptibility, perceived barriers, self-efficacy, other cancer screening experiences were significantly associated with higher compared to lower Precaution Adoption Process Model(PAPM) stages. Conclusions: This study appears to be applicable of the Precaution Adoption Process Model to understanding stomach cancer screening behavior. Our results suggest that it is needed to develop the tailored message for adherence of stomach cancer screening.

Cancer, like any disease, is a pathologic biological process. Drugs are designed to interfere with the pathologic process and should therefore also be validated using a functional screening method directed at these processes. Screening for cancers at an appropriate time and also evaluating results is also very important. Volumetric measurement helps in better screening and evaluation of tumors. Volumetry is a process of quantification of the tumors by identification (pre-cancerous or target lesion) and measurement. Volumetric image analysis allows an accurate, precise, sensitive, and medically valuable assessment of tumor response. It also helps in identifying possible outcomes such disease progression (PD) or complete response as per Response Evaluation Criteria in Solid Tumors (RECIST).

With the continuous advancement in electronics technology, especially the usage of new materials and the introduction of new and immature manufacturing process, stress and time dependent types of physical, chemical and mechanical imperfections are introduced to the electronic hardware. These types of imperfections are called flaws. A reliability stress screening process(RSS) is a process which involves the application of operational and/or environmental stress to electronic hardware on a 100% basis, for the purpose of precipitating inherent, as well as process-induced, flaws while neither destroying nor degrading in a significant way the hardware being stressed.
