With the burden of chronic diseases mounting among the population as a result of its aging, the importance of health examination is being stressed in order to identify and manage diseases in the early stage. Health examination in Korea is divided largely into periodic health examination provided as a national health screening program and individual physical checkups. The advantages of the former include little economic burden on the examined and those of the latter include the freedom of the individual to select various examination headings depending on the individual's characteristics and preferences. With both examinations now being expanded, empirical analyses from various standpoints are needed. This study proposes to analyze traits of the examined and non-examined as shown in the facts and figures of the 1st and 2nd Korean Longitudinal Study of Ageing (KLoSA), thereby make the determinant factors clear leading to the acceptance of the examinations, and analyze the effects of the examinations upon maintaining or moving to healthy lifestyle. It was confirmed that demographic features such as gender and age, socioeconomic features such as the level of education, place of residence and household income, physical and mental state of health such as chronic disease and dementia, and daily living habits are significantly related with whether to accept physical examination. It is also confirmed that physical examination leads to non-smoking, regular physical exercises and regular dietary habits. It is suggested that, to enhance effects of health examinations, follow-up management programs making use of results of health examinations be further expanded, and the national health screening program be more actively put into operation for the bracket lying in the blind spot of the program.

Fusarium head blight (FHB) is a devastating fungal disease of wheat (Triticum aestivum L.). The lack of genetic resources with stable FHB resistance combined with a reliable and rapid screening method to evaluate FHB resistance is a major limitation to the development of FHB resistant wheat germplasm. The present study utilized an immature wheat spike culture method to screen wheat spike culture derived variants (SCDV) for FHB resistance. Mycotoxin concentrations determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) correlated significantly (P < 0.01) with FHB severity and disease progression during in vitro spike culture. Selected SCDV lines assessed for FHB resistance in a Fusarium field disease nursery in Carman, Manitoba, Canada in 2016 showed significant (P < 0.01) correlation of disease severity to the in vitro spike culture screening method. Selected resistant SCDV lines were also crossed with an elite cv. CDC Hughes and the progeny of F₂ and BC₁F₂ were screened by high resolution melt curve (HRM) analyses for the wheat UDP-glucosyl transferase gene (TaUGT-3B) single nucleotide polymorphism to identify resistant (T-allele) and susceptible (G-allele) markers. The progeny from the crosses were also screened for FHB severity using the immature spike culture method and identified resistant progeny grouped according to the HRM genotyping data. The results demonstrate a reliable approach using the immature spike culture to screen for FHB resistance in progeny of crosses in early stage of breeding programs.

Background: Korea National Health Checkup Programs are aimed at the prevention and early detection of cardiovascular disease in adults. To establish a countermeasure for this tendency, The current Korea National Health Checkup Programs have been providing Health Risk Appraisal (HRA) since 2009, thereby focusing on individual lifestyle correction. However, from 2018, the dyslipidemia screening exam cycle has been changed from 2 to 4 years. Methods: In this study, we try to investigate whether policy decisions are valid based on domestic reports that have influenced policy decisions. First, considering the epidemiology of the domestic cardiovascular disease, dyslipidemia, and metabolic syndrome, the change of the 4-year cycle is appropriate or not. Second, whether the research method that applies came to make policy decisions appropriate or not. Third, our study also investigates whether the direction of policy decision was suitable for the second comprehensive national examination plan. Results: The data that are used in the previous study were that of 10 years ago and there also was a problem in selecting the data, especially the use of one of the research methods to calculate the signal to noise ratio that was aimed at improving health had some problems. This is a research method that does not match with the aim itself. Conclusion: Changing the screening cycle for dyslipidemia does not match the recent trend of general screening to effectively prevent cardiovascular disease in improving individual lifestyles in the national health checkup plan. Studying the relationship with metabolic syndrome, which can be an intermediate stage of cardiovascular disease, could be a policy direction that is more suitable for the national health examination comprehensive plan.

Objectives: In women, breast cancer is the most common cancer and the leading cause of cancer death. Screening tests are the basis for early diagnosis. In Iranian women, the mortality rate of breast cancer is high due to insufficient screening examinations and delayed visits for care. Therefore, this study aimed to determine the factors affecting breast self-examinations among Iranian women employed in medical careers. Methods: This cross-sectional study included 501 women working in the medical professions at Hamadan University of Medical Sciences in western Iran in 2018. The subjects were selected by stratified random sampling. Data were collected using a researcher-developed, self-report questionnaire that contained demographic information and questions based on protection motivation theory and social support theory. Descriptive data analysis was conducted using SPSS version 23 and model fitting with PLS version 2. Results: The mean age of the participants was $37.1{\pm}8.3years$, and most of the women (80.4%) were married. Most women had a bachelor's degree (67.5%). The findings of this study showed that the coping appraisal construct was a predictor of protection motivation (${\beta}=0.380$, p<0.05), and protection motivation (${\beta}=0.604$, p<0.05) was a predictor of breast self-examination behavior. Additionally, social support theory (${\beta}=0.202$, p<0.05) had a significant positive effect on breast self-examination behavior. Conclusions: The frequency of practicing self-examinations among women employees in the medical sector was low; considering the influence of social support as a factor promoting screening, it is necessary to pay attention to influential people in women's lives when designing educational interventions.

IVA는 상염색체 열성의 유전방식을 보이는 leucine 대사 장애 질환이자 대표적인 유기산 혈증이다. IVD 유전자의 돌연변이에 의한 isovaleryl-CoA dehydrogenase 효소의 결핍이 질환 발생의 원인이다. Isovaleryl-CoA dehydrogenase 효소가 결핍되면 isovaleryl-CoA의 대사물질이 비정상적으로 체내에 축적되어 대사성 산증 및 고암모니아혈증 등의 급성 대사성 위기와 발달지연, 성장지연, 및 경련성질환 등의 만성 합병증을 초래할 수 있기 때문에, 급성 대사성 위기 및 만성합병증의 발생을 예방하기 위해 조기 진단에 따른 적절한 치료의 도입이 중요하다. 현재 IVA은 국내에서 시행되는 탠덤 매스 스크리닝법을 이용한 신생아 대사질환 선별검사 항목에 포함되어 있으며, C5의 상승으로 의심할 수 있다. 그러나 SBCAD 결핍증 혹은 pivalic acid 유래물이 포함된 항생제를 투여한 경우에도 C5의 상승이 동반될 수 있기 때문에, 감별진단 및 확진을 위한 추가적인 생화학적, 유전학적 검사가 필수적이다.

Purpose: From the early 1990's, use of Tandem mass spectrometry in neonatal screening test, made early stage detection of disorders that was not detectable by the previous methods of inspection. This research aims to evaluate the frequency of positive results in national neonatal screening test by Tandem mass spectrometry and its usefulness. Methods: A designated organization for inherited metabolic disorder executed neonatal screening test on newborns using Tandem mass spectrometry from January 2006 to December 2015, followed by the investigation of these data by the Planned Population Federation of Korea (PPFK), and this research analyzed those inspected data from the PPFK. Results: Among total childbirth of 4,590,606, from January 2006 to December 2015, 3,445,238 were selected for MS/MS and conduction rate was 75.1%. 261 out of the selected 3,445,238 were confirmed patients and for last decade, detection rate of total metabolic disorder was 1/13,205. In 261 confirmed patients, 120 had an amino acid metabolic disorder and its detection rate was 1/28,710 and 110 had an organic acid metabolic disorder and detection rate was 1/31,320. Also, 31 had a fatty acid metabolic disorder and detection rate was 1/13,205. Conclusion: Inherited metabolic disorder is very rare. Until now, it was difficult to precisely grasp an understanding on the national incidence of inherited metabolic disorder, due to lack of overall data and inconsistent and incomplete long-term result analysis. However, this research attempted to comprehensively approach the domestic incidence, by analyzing previous 10 years of data.

In the past, hepatitis B virus (HBV) infection was endemic in the general Korean population. The association of HBV infection with the occurrence of liver cancer has been well demonstrated in several epidemiologic studies. While the mortality rates of liver cancer in Korea have decreased steadily over the last decade, the presence of hepatitis B surface antigen (HBsAg) in mothers remains high at 3-4%, and 25.5% of these HBsAg positive mothers are positive for hepatitis B e antigen (HBeAg). HBV infection caused almost a quarter of hepatocellular carcinoma (HCC) cases and one-third of deaths from HCC. These aspects of HBV infection prompted the Korean government to create a vaccination program against HBV in the early 1980s. In 1995, the Communicable Disease Prevention Act (CDPA) was reformed, and the government increased the number of HBV vaccines in the National Immunization Program (NIP), driving the vaccination rate up to 95%. In 2000, the National Health Insurance Act (NHIA) was enacted, which provided increased resources for the prevention of perinatal HBV infection. Then in 2002, the Korean government, in conjunction with the Korean Medical Association (KMA), launched an HBV perinatal transmission prevention program. The prevalence of HBsAg in children had been high (4-5%) in the early 1980s, but had dropped to below 1% in 1995, and finally reached 0.2% in 2006 after the NIP had been implemented. After the success of the NIP, Korea finally obtained its first certification of achievement from the Western Pacific Regional Office of the World Health Organization (WPRO-WHO) for reaching its goal for HBV control. An age-period-cohort analysis showed a significant reduction in the liver cancer mortality rate in children and adolescents after the NIP had been implemented. In addition to its vaccination efforts, Korea launched the National Cancer Screening Program (NCSP) for 5 leading sites of cancer, including the liver, in 1999. As a consequence of this program, the 5-year liver cancer survival rate increased from 13.2% (1996-2000) to 23.3% (2003-2008). The development of both the primary and secondary prevention for liver cancer including HBV immunization and cancer screening has been of critical importance.

Background: Breast and cervical cancers are the most common causes of cancer mortality among women in India, but actually they are largely preventable diseases. Although early detection is the only way to reduce morbidity and mortality, there are limited data on breast and cervical cancer knowledge, safe practices and attitudes of teachers in India. The purpose of this study is to assess the level of awareness and impact of awareness programs in adoption of safe practices in prevention and early detection. Materials and Methods: This assessment was part of a pink chain campaign on cancer awareness. During cancer awareness events in 2011 at various women colleges in different parts in India, a pre-test related to cervical cancer and breast cancer was followed by an awareness program. Post-tests using the same questionnaire were conducted at the end of the interactive session, at 6 months and 1 year. Results: A total of 156 out of 182 teachers participated in the study (overall response rate was 85.7 %). Mean age of the study population was 42.4 years (range- 28-59 yrs). There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of breast self examination (BSE) was significantly more frequent in comparison to CBE, mammography and the Pap test. Magazines and newspapers were sources for knowledge regarding screening tests for breast cancer in more than 60% of teachers where as more than 75% were educated by doctors regarding the Pap test. Post awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons for not doing screening test were found to be ignorance (50%), lethargic attitude (44.8%) and lack of time (34.6%). Conclusions: Level of knowledge of breast cancer risk factors, symptoms and screening methods was high as compared to cervical cancer. There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of BSE was significantly greater in comparison to CBE, mammography and the Pap test. To inculcate safe practices in lifestyle of people, awareness programmes such as pink chain campaign should be conducted more widely and frequently.

포도 노균병 저항성 품종육성에 필요한 포도 품종간 저항성 검정체계를 확립하고 품종간의 저항성을 비교하고자 본 시험을 수행하였다. 포도 노균병에 대한 품종간 저항성 검정에는 $10^4-10^5spores/mL$의 포자현탁액을 분무접종하여도 큰 차이는 없었으나 $5{\times}10^4spores/mL$로 조절된 포자현탁액을 분무접종하는 것이 효과적이었다. 포도 노균병균을 온실에서 분무접종한 결과 Campbell Early, Niagara 등의 품종은 저항성, Sheridan, 청수(淸水) 등의 품종은 중도저항성, Kaiji, Red Queen, Ruby Okuyama 등의 품종은 감수성을 나타내었다. 포장에서의 저항성은 V. vinifera에 속하는 포도 품종이 V. vinifera-labrusca hybrids, V. vinifera-labrusca-aestivalis hybrids, V. vinifera-labrusca-aestivalis에 V. riparia, V. rupestris, V. lincecumii 등이 단독 또는 복합적으로 추가된 hybrids에 비해 감수성이었으며, 특히 V. vinifera-labrusca hybrid에서는 4배체 품종이 2배체 품종에 비해 감수성이었다. 온실 내에서 병원균 포자의 분무접종을 통한 품종간 저항성 검정 결과와 포장상태에서의 저항성 결과는 유사한 경향을 나타내었으므로 온실 내에서의 저항성 검정방법이 포도 노균병 저항성 검정에 이용될 수 있을 것이다.
