Rice is the world's most important food crop and a major source of nutrition for about two thirds of populations. Northern Vietnam is one of the most important centers of genetic diversity for cultivated rice. In this study, we determined the genetic diversity and population structure of 79 rice landraces collected from northern Vietnam and 19 rice accessions collected from different countries. In total, 98 rice accessions could be differentiated into japonica and indica with moderate genetic diversity and a polymorphism information content of 0.382. We also detected subspecies-specific markers to classify rice (Oryza sativa L.) into indica and japonica. Additionally, we detected five marker-trait associations and rare alleles that can be applied in future breeding programs. Most interestingly, analysis of molecular variance (AMOVA) found genetic differentiation was related to geographical regions with an overall PhiPT (analog of fixation index FST) value of 0.130. More emphasis was given to provide signatures and infer explanations about the role of geographical isolation and environmental heterogeneity in genetic differentiation among regions in landraces from northern Vietnam. Our results suggest that rice landraces in northern Vietnam have a dynamic genetic system that can create different levels of genetic differentiation among regions, but also maintain a balanced genetic diversity between regions.

The prevention of porcine respiratory disease complex (PRDC) is very important because of its high infection-rates in the swine farms and the economic impact in swne industry in Korea. To control the prevalence of PRDC, it is important to know about infection patterns of it. Therefore, this study aimed to investigate the infection patterns of PRDC in the northern area of Gyeongsangnam-do. To this end, the infection of porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), Actinobacillus pleuropneumoniae (APP), Mycoplasma hyopneumoniae (MH), and Swine influenza virus (SIV) were examined using 120 pig lung tissues by PCR analysis. As a result, single pathogen positive specimens were 25.0% and the others (75.0%) were turned out to be PRDC with at least two pathogens. Among PRDCs, 50 specimens (41.7%) was infected with PRRSV, PCV2, MH and SIV. Ten specimens (8.3%) showed triple infections of PRRSV, PCV2 and MH. Double infected specimens for PRRSV and PCV2 were 10 (8.3%), and for PCV2 and APP were 20 (16.7%).

This paper investigated and analyzed the status of students for jobs in textile industry for proposing the basic data for more effective labor supply to textile industry in northern region of Gyeonggi-do. The survey was conducted with 55 students in the middle aged class living in northern region of Gyeonggi-do who participated in the field practice education program related to industry business from April to June, 2013. The analysis results are described as below. For the satisfaction on the curriculum, 45.5% of the subjects showed the highest satisfaction on the education program. 65.5% desired the full-time employment in the textile business after the education. 78.2% of the subjects agreed that the education program for helping employment and recruitment in textile industry was the essential project in the current reality when there is a serious lack of field workers. Significant number of subjects answered that the education program should be implemented through the academy and business cooperation between the relevant departments in colleges and textile business. Although the subjects in this paper were very limited, the survey results would be important data to prepare the approach for improving the supply and demand of labor in textile business in the future as well as the starting point for a project to create new jobs for middle-aged women in the Northern region of Gyeonggi-do.

의성 지역에서 재배하기 적합한 국내 한지형 마늘을 선발하고자 '의성', '예천', '단양', '정선' 및 '용인' 등 한지형 마늘 5종을 공시하여 생육특성과 수량성을 조사하였고, 난지형 마늘의 재배 적합성을 검증하기 위해 '남도' 마늘을 동시에 공시하였다. 국내 지방 재배종 마늘의 생장특성은 생태형에 따라 차이를 보여 난지형인 '남도'가 초기생장과 숙기가 빨랐던 반면, 한지형 지방종간에는 뚜렷한 차이가 없었다. 추대 현상에 있어서는 '정선'과 '용인'이 추대율이 낮았고 불완전 추대가 많았던 반면, '예천'과 '의성'은 추대율이 높고 '의성'은 2차생장률이 낮았다. 의성지방에서 재배된 한지형 마늘 중에 '예천'의 수량이 높았으며 생장 최성기에 타 품종에 비하여 작물생장률도 높았다. 의성 지역에서 재배된 '정선', '용인' 및 '단양'은 '의성'에 비하여 생산성이 낮은 것으로 평가되었다.

This study was conducted to investigate antibiotic resistance among Salmonella Typhimurium isolates from diseased pigs in Gyeongbuk province during the period 1998~2011. One hundred forty one isolates were tested for antibiotic resistance using the standard disk diffusion method and were examined for presence of resistance gene by PCR method. S. Typhimurium showed high drug resistance rates to tetracycline (95.7%), streptomycin (93.6%), ampicillin (86.5%), cephalothin (80.1%), gentamicin (79.4%), and trimethoprim/sulfamethoxazole (72.3%). Resistance gene, blaTEM, blaPSE1, tetA, tetB, tetG, sul1, sul2, aadA, strA, grm, and temA were detected among the antibiotic resistance isolates and temB, tetC, aadB gene were not detected. One hundred twenty one (89.6%) tetA, two (1.5%) tetB and one (0.7%) tetG gene were detected in the 135 tetracycline resistant isolates. Two (1.6%) temA gene were detected in one hundred twenty two ampicillin resistance isolates and temB was not detected.

Multiple genetic studies have confirmed association of 8q24 variants with susceptibility to prostate cancer (PCa). As PCa risk SNPs may also influence disease outcome, we studied here eight 8q24 risk alleles, and evaluated their role in PCa clinical covariates in northern Chinese men. Blood samples and clinical information were collected from ethnically Chinese men from Northern China with histologically-confirmed PCa (n=289) and from age-matched normal controls (n=288). Eight 8q24 SNPs were genotyped by polymerase chain reaction-high- resolution melting analysis in 577 subjects. We examined the prevalence distribution of 8q24 risk alleles and analyzed the associations between the risk allele and PCa and clinical covariates to infer their impact on aggressive PCa. Three of the eight SNPs were associated with PCa risk in northern Chinese men, including rs16901966 (OR 1.31, 95% CI 1.01-1.70, p=0.042), rs1447295 (OR 1.47, 95% CI 1.09-1.98, p=0.011) and rs10090154 (OR 1.55, 95% CI 1.14-2.12, p=0.005). Haplotype analysis based association with the risk alleles revealed significant differences between cases and controls (OR 1.43, 95%CI 0.99-2.06, p=0.049). The risk alleles rs16901966, rs1447295 and rs10090154 were associated with age at diagnosis and tumor stage as compared with controls, while rs16901966 was associated with aggressive PCa (OR 1.43, 95% CI 1.01-2.03, p=0.042). The evidence for 8q24 SNPs with PCa risk in northern Chinese men showed rs16901966, rs1447295 and rs10090154 at 8q24 (region 1, region 2) to be strongly associated with PCa and clinical covariates. The three SNPs at 8q24 could be PCa susceptible genetic markers in northern Chinese men.

The survey was conducted with 143 companies related to textile and fashion industry in the northern region in Gyeonggi-do and the questionnaires from 126 companies were finally analyzed to get the statistic data. The questionnaire includes 19 questions and the survey was conducted from March to May 2010. In accordance with the analysis, the most urgent issue in the textile and fashion industry was the supply of manpower in the field. For the solution against the insufficiency of manpower, employment of foreigners showed the highest ratio, 47.4%. For the reasons why the number of foreign workers was increased, the insufficiency of the Korean workers showed the highest point, 62.9%. For the questions related to the conditions of regional industries, answered that the textile industry in the northern region in Gyeonggi-do would be very prospective as the future industry. There was a number of respondents who agreed that high-tech textile industry including knitting could be the industry creating the new highly added value. More than half of the respondents agreed that the textile industry contributed on strengthening the national competitiveness, boosting the development of national industry, helping the creating the jobs and dealing with the unemployment among young people. Accordingly, it was concluded that the perspective on the textile and fashion industry was positive.
