  • A cross-sectional study was conducted among nursing staff of a missionary hospital of Delhi in June 2009. All the nurses were invited to participate in the training programme on breast cancer and techniques of breast self examination (BSE). A questionnaire was administered to all 259 participants seeking information on their level of awareness regarding breast cancer and relevant screening guidelines. With the help of 5 training workshops all the nurses were imparted training regarding the most appropriate technique of doing breast self exams. The mean age of the participants was 35.8 years. Out of a total of 259 nursing staff members 77.2% correctly answered all the 10 questions regarding high risk factors for breast cancer and after the training programme this increased to 100% (p<0.05). Only 65.2% of the participants gave correct responses to all the 8 questions regarding correct technique of performing a BSE, which after the training programme increased to 99.3% (p<0.05). At the baseline only 56.8% knew all the three screening methods correctly and after the intervention 98.7% could correctly mark the responses regarding screening (p<0.05). The actual practice of following the screening guidelines amongst the nursing staff was poor. Only 26 (10.03%) had ever done a BSE, none performed it monthly, 58 (22.4%) had ever gone themselves for a CBE and 18 (6. 94%) had ever undergone mammography.

  • The exposure of food to ionizing radiation has been recognized as a safe and effective mode of food preservation in more than 55 countries. The benefits include eradication of insect pests, inactivation of food pathogens, extension of shelf-life, and improvement in food hygiene. Regulatory authorities around the world have emphasized the implementation of various national and international regulations to facilitate trade and development of consumers' confidence in purchasing irradiated foods. Therefore, the need for reliable irradiation detection methods has increased to enforce these regulations. At present, a number of promising analytical approaches have been developed and evaluated. Moreover, about 10 European Standards have been adopted as General CODEX Alimentarius methods for the detection of irradiated foodstuffs. However, most of these methods demand relatively expensive equipment and prolonged sample preparation. Therefore, simple and cost-effective approaches would be advantageous for rapid screening of foodstuffs. The suspected samples need to be analyzed further with more validated techniques to confirm the screening results. In this review, existing screening methods (i.e. physical, chemical, and biological) for the identification of irradiated foods have been outlined along with their principles, scopes and limitations.

  • Water deficit is a serious constraint to soybean [Glycine max L. (Merr.)] production in rainfed regions of Asia, Africa, and America. This study was conducted to develop a simple and effective screening method for drought tolerance in soybean. Fifteen soybean cultivars, eight identified to be drought-tolerant and seven drought-sensitive in previous studies, were used for the evaluation of drought tolerance under the new screening conditions. The seedling screening method was consisted of a treatment in a PEG solution and drought treatment in parafilm-layered pots. 5-day-old seedlings were treated in a 18% PEG solution for 4 days and their wilting and hypocotyl browning were recorded. Three seedlings grown in a parafilm-layered pot containing peat moss were drought-stressed by withholding water from the third day after seedling emergence, and root and seedling growth were examined. Degree of drought tolerance were rated based on seedling vigor in the PEG solution and drought-stressed parafilm-layered pots, and also on the penetration ability of roots through parafilm layer. Most of seedlings of the drought-tolerant cultivars showed higher vigour and root penetration than those of the drought-sensitive cultivars under the new screening conditions. Our results indicate that the new method can be used as a simple and effective screening procedure for drought tolerance in soybean breeding programs.

  • We designed an effective screening method for double strand DNA (dsDNA) binders using DNA-modified magnetic particles. Hairpin DNA was immobilized on the surface of magnetic particle for a simple screening of dsDNA binding materials in a solution containing various compounds. Through several magnetic separation and incubation processes, four DNA-binding materials, DAPI, 9AA, AQ2A, and DNR, were successfully screened from among five candidates. Efficiency of screening was demonstrated by HPLC analysis using a C2/18 reverse-phase column. In addition, their relative binding strengths were verified by measuring the melting temperature ($T_m$). If hairpin DNA sequence is modified for other uses, this magnetic bead-based approach can be applied as a high-throughput screening method for various functional materials such as anti-cancer drugs.

  • A visual stress may provoke migraine, cephalalgia, intervene a long term reading and learning capability and reduce the productivity of a laborer who uses computer for a good while. In this study, a web based screening tool for visual stress was developed, it applied to 72 visually normal young persons in parallel with traditional questionnaire about symptoms of visual stress. To estimate visual stress, It is proposed to measure difference of visual search time of Han Gul characters as targets between visual stressful pattern and non-visual stressful pattern as global background of characters. As a result of test, 5 subjects were screened whose mean visual search time in the stressful pattern with 6 CPD spatial frequency increase significantly more than in none stressful pattern(t-test, one-tailed, p=$1.0407\times10^{-11}$). 2 of them were diagnosed as mild visual stress syndrome in the clinic. None had visual distortion and 50% of subjects had visual discomfort in results of the questionnaire. Correlation between visual search time increase rate and normalized number of visual discomfort may be slight(C. coefficient=0.1355). This study may contribute as a basic research for screening person with migraine, visual reading disabilities and VDT syndrome. It is required to apply the test to visual reading disabilities, migraine with visual distortion and/or visual discomfort as well as normal person for higher reliability of the screening tool.

  • Purpose: To identify the status of regular cervical cancer screening practices among middle-aged women, the associations between regular practice and research factors, and the predictive model and factors effecting such behavior was studied. Method: Two hundred women, aged 40 to 60, were selected by convenience in one urban area of Seoul. They were asked about their regular attendance for screening, knowledge of cancer and screening, health belief, health self-determination index and certain personal factors. Result: Approximately 54.5% of the women had periodic screening tests every 6 months to 2 years. Their knowledge of cervical cancer and health belief were at the medium level of each scale, but their health self-determination scores (HSDI) were low. Some influencing factors, and their cancer odds ratio were identified through univariate regression analysis. These variables were included in a predictive model, and this model proved to have enough fit and classification power (83.5%). In this model, the financial state, self-belief and self-determination scores were found to be significant. Conclusion: Middle-age women's intrinsic motivation for healthy behavior was found to be low in those who felt to be in a poor financial state, had higher perceived barriers, lower perceived benefits and a lower prevalence of undergoing regular screening test.

  • The purpose of this study was to explore the experience of Pap smear screening of menopausal women in W city using a phenomenological methodology. The participants were 5 focus groups consisting of 37 menopausal women. They were selected using snowball sampling method. The data were collected through focus group interviews. Data were recorded and analyzed by Colazzi's method. Significant statements were extracted from the data resulting in 20 themes. These themes formed 12 clusters and 5 categories. The essential themes of the experience of cervical cancer screening emerged as : "unpleasant feelings during procedure", "ambivalent feelings about results", "be guided to seek health", "shrink from interaction with health professionals", "at ease about cervical cancer". The results indicated that cervical cancer prevention strategies for menopausal women need to be based on deep under standing of the personal experiences of Pap smear screening. In conclusion, it is suggested that more specified strategies are needed for menopausal women to encourage them to have regular screening.

  • Purpose: This study evaluates the effect of behavioral relaxation training on distress and cancer screening intention of patients with upper gastrointestinal endoscopy. Methods: The research was conducted in a non-equivalent control group posttest design. Data were collected from endoscopy subjects in B city from October to November of 2018. Fifteen minutes of behavioral relaxation training were provided to the experimental group (n=40) and traditional relaxation therapy methods were provided to the control group (n=40). Outcome measures were distress and cancer screening intention of patients with upper gastrointestinal endoscopy. Data were analyzed with a ${\chi}^2$-test, independent t-test, Fisher's exact test with SPSS/PC version 23.0. Results: The objective discomfort (t=8.81, p<.001) of the experimental group was lower than that of the control group; there were no significant differences in the subjective discomfort (t=1.73, p=.088). The cancer screening intention (t=-5.85, p<.001) of the experimental group was significantly higher than that of the control group. Conclusion: Behavioral relaxation training was effective in heightening cancer screening intention. Therefore it can be usefully applied to increase cancer screening intention.

  • Korea's Corona 19(COVID-19) quarantine, referred to as 'K-Quarantine', is a globally recognized quarantine system that has achieved both conflicting goals: health and economy. The quarantine system represented by 3T(Test-Trace-Treat) is not a method of blocking an area, but a method of screening and treating infected and non-infected persons. The screening center, one of the key elements of this screening treatment system, has evolved to suit the timing and situation of COVID-19, and has succeeded in initial response by conducting large-scale tests quickly and safely. By analyzing the evolution of screening centers that produced such significant results from a problem-solving point of view, it proved its meaning as a practical success case of creative problem-solving. In addition, the usefulness of TRIZ (Russian abbreviation of Theory of Solving Inventive Problem), a creative problem-solving theory, was confirmed through an analysis of actual verified cases of COVID-19 response. TRIZ is a problem-solving theory created by analyzing the regularity of invention patents, and is widely used not only in the technical field but also in the non-technical fields such as design, management, and education. The results of this study are expected to provide useful meaning and practical examples to researchers interested in system analysis and TRIZ application from a problem-solving perspective.
