  • Post-weaning diarrhoea (PWD) and oedema disease (ED) caused by E. coli F18 always result in economic losses to pig producers, and no effective methods of controlling PWD and ED are presently available. FUT1 has been identified as a candidate gene controlling the expression of E. coli F18 receptor. This study examined the correlation between F18ab and F18ac adhesion phenotypes and the polymorphism at position M307 of the FUT1 gene in three pig breeds (231 Large White, 107 Landrace and 109 Songliao Black). The results showed: i) Both the susceptible genotypes (GG and GA) and the adhesion phenotypes (adhesive or weekly adhesive) were dominant in all three breeds with frequencies over 95%. ii) Three adhesion patterns of the two F18 variants F18ab and F18ac, i.e., ($ab^+$, $ac^+$), ($ab^+$, $ac^-$) and ($ab^-$, $ac^-$), were found in all three breeds, and there was no significant difference in the distribution of adhesion phenotypes of the two variants (separately or jointly) among the three breeds (p>0.05). iii) The FUT1 M307 genotypes were completely associated with the F18ab adhesion phenotypes and very strongly associated with the F18ac adhesion phenotypes. All individuals of genotype AA were non-adhesive to both F18ab and F18ac. All individuals of genotype GG or GA were adhesive to F18ab, whereas 11% of them were non-adhesive to F18ac. These results suggest that the polymorphism at FUT1 M307 can be used for marker-assisted selection of PWD and ED resistant pigs.

  • Due to rapid industrialization and economic development since 1970's, Seoul has become known as one of the most heavily polluted cities in the world. This is especially because of its air pollution. This study was conducted to characterize the cancer risk from organic pollutants in the suspended particulates of Seoul. Extractable organic matter (EOM) and PAHs in Shinchon, a major traffic area, were measured monthly in two periods of Aug. $1987{\sim}sep.$ 1988, and Sep. $1990{\sim}Aug.$ 1991. While the differences both of EOM and benzo(a)pyrene concentrations between these two periods were not significant (P>0.05), the differences between heating and non-heating seasons were significant (p<0.01). The estimated mean concentrations of EOM and benzo(a)pyrene in fine particles in non-heating season were $3.98{\mu}g/m^3\;and\;0.51ng/m^3$ respectively, and in heating season were $6.75{\mu}g/m^3\;and\;2.96ng/m^3$ respectively, in these two periods combined. The calculated risk from EOM was compared with that from benzo(a)pyrene and also these values were compared with the level of acceptable risk.

  • The purpose of this study is to describe the characteristics associated with the hypertension educated population, and to develop and analyze a simple predictive model of the hypertension management education status. Based on the Korea National Health and Nutrition Examination Survey in 2008, a cross-sectional design was used in this study. An effective 1.165 adults(${\geq}30$) sample was divided into a participation group (n=66) and a non-participation group(n=1,099), and to compare demographic, socio-economic and health characteristics between two groups. Moreover, predictors associated with participation in hypertension education programs were identified by the logistic regression analysis. The participation rate in hypertension education in Korea is only 5.7% which is vastly low given the various programs were provided, and there are statistically significant differences between a participation group and a non-participation group in age(p=0.050), marital status(p=0.002), education level(p=0.000), and residence area(p=0.037). Furthermore, age for 40-49 years(OR : 0.207), education level of high school(OR : 2.579) and college(OR : 6.417), duration of hypertension(OR : 1.044), CVA(OR : 2.463), and blood pressure(OR : 1.041) are statistically significant predictors associated with the participation in hypertension education programs. To increase the participation of hypertension education program, variables such as age, education level, duration of hypertension, CVA, and blood pressure are more concerned. And, high-risk patients and family members need targeted outreach programs.

  • In response to the increasing emphasis being placed on the importance of international cooperation as part of global efforts to cope with growing non proliferation, and security, concerns in the nuclear field, the Director General of the International Atomic Energy Agency (IAEA), Mohamed ElBaradei, appointed an international group of experts to consider possible multilateral approaches to the nuclear fuel cycle. The mandate of the Expert Group was three fold: ${\bullet}$ To identify and provide an analysis of issues and options relevant to multilateral approaches to the front and back ends of the nuclear fuel cycle; ${\bullet}$ To provide an overview of the policy, legal, security, economic, institutional and technological incentives and disincentives for cooperation in multilateral arrangements for the front and back ends of the nuclear fuel cycle; and ${\bullet}$ To provide a brief review of the historical and current experiences and analyses relating to multilateral fuel cycle arrangements relevant to the work of the Expert Group. The overall purpose was to assess MNAs in the framework of a double objective: strengthening the international nuclear non proliferation regime and making the peaceful uses of nuclear energy more economical and attractive. The Group identifies options for MNAs - options in terms of policy, institutional and legal factors - for those parts of the nuclear fuel cycle of greatest sensitivity from the point of view of proliferation risk. It also reflects the Groups deliberations on the corresponding benefits and disadvantages (pros and cons) of the various options and approaches. Although the Expert Group was able to agree to forward the resulting report to the Director General, it is important to note that the report does not reflect agreement by all of the experts on any of the options, nor a consensus assessment of their respective value. It is intended only to present options for MNAs, and to reflect on the range of considerations which could impact on the desirability and feasibility of those options.

  • 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.

  • Health at infancy and early childhood is considered an important factor for healthy life thereafter. Concept of nursing is inclusive not only of physical care but also psycho-social aspect in order to help achieve maximum state of wellness. Statistical studies reveal concept and structure of family and home tends to change towards nuclear type, ratio of female occupancy tends to increase. These tendencies will influence the method of infants and children. Purpose of this study is to investigate the characteristics of mothers and their children with and without occupation, method of nurturing and analyse data according to various variables, in arnder to give data for care for infants and children. During the period of June 12 though July 22, 1973, 98 mothers and their 224 children; 53 mothers with occupation with 110 children and 45 mothers without occupation with 114 children were Interviewed indirectly through check list. Results of the studies are as follows: 1. Hypothesis 1 ; Tendencies of finger sucking will be greater in children of occupant mothers due to lack of maternal love. Through chi-square examination significant difference is revealed by P>0.05 level, therefore Hypothesis 1 is rejected. (X²=0.24) 3. Hypothesis 2; of occupant mothers tend to have had wanted number of children through family planning. Ratio of wanted versus unwanted children were tested and significant difference is revealed by P<0.05 1eve1. Hypothesis 2 is supported. (X²=8.398). 3. Hypothesis 3: Non-occupant mothers tend to cuddle more while feeding infants. Significant difference Is revealed through Chi-square test by P〈0.05 level. Hypothesis 3 is rejected. (X²=4.34) Conclusion and recommendations: Occupant mothers' higher degree of interest and consideration compared to that of non-occupant mothers in regard to nurturing of their children have been ascertained by this study. These results fight have come up due to the differences of socioeconomic and cultural status of respondents. Further studies on each variable between mothers with and without occupation with similar socio-economic and cultural background are recommended.

  • Background: To evaluate the value of combined detection of serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1), and carbohydrateantigen 125 (CA125) for the clinical diagnosis of nonsmall cell lung cancer (NSCLC). Materials and Methods: Serum CEA, CYFRA21-1 and CA125 were assessed in 140 patients with NSCLC, 90 patients with benign lung disease and 90 normal control subjects, and differences of expression were compared in each group, and joint effects of these tumor markers in the diagnosis of NSCLC were analyzed. Results: Serum CEA, CYFRA21-1 and CA125 in patients with NSCLC were significantly higher than those with benign lung disease and normal controls (P<0.05). The sensitivity of CEA, CYFRA21-1 and CA125 were 49.45%, 59.67%, and 44.87% respectively. As expected, combinations of these tumor markers improved their sensitivity for NSCLC. The combined detection of CEA + CYFRA21-1 was the most cost-effective combination which had higher sensitivity and specificity in NSCLC. Elevation of serum CEA and CYFRA21-1 was significantly associated with pathological types (P<0.05) and elevation of serum CEA, CYFRA21-1 and CA125 was significantly associated with TNM staging (P<0.05). Conclusions: Single measurement of CEA, CYFRA21-1 and CA125 is of diagnostic value in the diagnosis of lung cancer, and a joint detection of these three tumor markers, could greatly improve the sensitivity of diagnosis on NSCLC. Combined detection of CEA + CYFRA21-1 proved to be the most economic and practical strategy in diagnosis of NSCLC, which can be used to screen the high-risk group.

  • Globally road transport networks are subjected to continuous levels of stress from increasing loading and environmental effects. As the most popular mean of transport in the UK the condition of this civil infrastructure is a key indicator of economic growth and productivity. Structural Health Monitoring (SHM) systems can provide a valuable insight to the true condition of our aging infrastructure. In particular, monitoring of the displacement of a bridge structure under live loading can provide an accurate descriptor of bridge condition. In the past B-WIM systems have been used to collect traffic data and hence provide an indicator of bridge condition, however the use of such systems can be restricted by bridge type, assess issues and cost limitations. This research provides a non-contact low cost AI based solution for vehicle classification and associated bridge displacement using computer vision methods. Convolutional neural networks (CNNs) have been adapted to develop the QUBYOLO vehicle classification method from recorded traffic images. This vehicle classification was then accurately related to the corresponding bridge response obtained under live loading using non-contact methods. The successful identification of multiple vehicle types during field testing has shown that QUBYOLO is suitable for the fine-grained vehicle classification required to identify applied load to a bridge structure. The process of displacement analysis and vehicle classification for the purposes of load identification which was used in this research adds to the body of knowledge on the monitoring of existing bridge structures, particularly long span bridges, and establishes the significant potential of computer vision and Deep Learning to provide dependable results on the real response of our infrastructure to existing and potential increased loading.

  • Since most construction workers comprehend information on work through sight, the importance of safety signs are increasing by the day. In Korea, due to the sharp economic progress and the higher standard of the workforce, since the end of 1980, each year the number of foreign workers entering the country who working simple technical jobs have increased this condition. This study researched safety signs, which are the final accident prevention measures at the workplace. Based on the study, comprehension of the standard safety signs of the Occupational Safety and Health Act (OSHA) was lacking at a level of 2.5. Also, the perception level of the Industry Public Safety Law (38%) was very low. And, it was found that sex and experience or non-experience in safety training was not an issue in the level of understanding. However, when satisfying the standards of the Occupational Safety and Health Act and changing the safety signs, the level of understanding went up to 3.49 and the perception level was increased significantly to 70%. Thus, it is concluded that, since the foreign workers are mainly from non-English speaking countries and because the workers of Korea are not familiar with English, in order to provide proper safety information, there must first of all be simplistic and concise pictograms. This will provide needed information and must be coupled with simple English words that can give additional information to the worker and be effective in helping him understand and perceive the safety sign. Also, it has been determined that the existing forms of safety signs and their effectiveness in industry accident prevention must be reassessed.

  • BACKGROUND: It is essential to prioritize the exact and clear understanding of agricultural nonpoint source pollution (NPS) controls. The realistic policies and systems should also be developed based on this understanding. Therefore, this study aimed to present agricultural Best Management Practices (BMPs) applicable for the fields based on the Delphi survey result. METHODS AND RESULTS: This study deduced the evaluation items to assess each BMP for agricultural NPS control and conducted the surveying using the Delphi method based on agricultural BMP experts. In addition, its on-the-spot application were evaluated. Considering its importance, technical, social and economic proprieties showed that political support was ranked first and followed by cost investment, labor investment, reduction effect and resident participation. The survey findings by agricultural BMP experts showed the good performance of on-the-spot application can be achieved from fertilization by soil testing, residue and green manure application and contour plowing which are applicable within a field. Agricultural BMPs, highly applicable for the fields, were the countermeasures that farmers who are the principal bodies of agricultural NPS control could be participated directly. CONCLUSION: The active participation of farmers is essential for effective control of agricultural NPS. It is necessary to establish various incentive systems.
