This paper examines the seismicity of the offshore area of western Canada in the light of findings from a detailed study of an earthquake swarm which occurred in the area during November-December in 1971. The distribution of epicenters and focal mechanism solutions of a few main events suggest that the seismicity of the area may largely be interpreted in terms of plate interactions among the Pacific, Juan de Fuca, Explorer and North American plates. Differences between the patterns of seismicity along the transform fracture zones and at their junctions with the ridges were also observed.

Background: The purpose of this study was to evaluate the potential association of five (p.P47S, p.R72P, PIN3 Ins16bp, p.R213R and r.13494g>a) polymorphisms of TP53 with the risk of developing breast cancer in North Indian Punjabi population. Methods: We screened DNA samples of 200 sporadic breast cancer patients (197 females and 3 males) and 200 unrelated healthy, gender and age matched individuals for the polymorphisms. Results: For the p.P47S polymorphism, we observed the PP genotype in 99.5% of the patients and PS genotype in only 1 patient. All the controls had the wild type PP genotype. The frequency of RR, RP and PP genotype of p.R72P was 23.5% vs 33.5%, 51.5% vs 45.5% and 25% vs 21% in patients and controls respectively. Heterozygous (RP) genotype was increased in breast cancer patients as compared to controls (51.5 vs 45.5%) and showed 1.61 fold significantly increased risk for breast cancer (OR=1.61, 95% CI, 1.01-2.58, p=0.04). In breast cancer patients the frequencies of A1A1, A1A2 and A2A2 genotypes of PIN3 Ins16bp polymorphism were 67%, 26% and 7% respectively whereas in controls the genotype frequencies were 68.5%, 27.5% and 4% respectively, with no significant difference. For p.R213R (c.639A>G), all individuals had homozygous wild type genotype. The frequencies of GG, GA and AA genotypes of TP53 r.13494g>a polymorphism were 62 vs 67.5%, 33 vs 28% and 5 vs 4.5% in patients and controls respectively, again without significant difference. We observed that RP-A1A1 genotype combination of p.R72P and PIN3 Ins16bp and RP-GG combination of p.R72P and r.13494g>a polymorphism showed significant risk of breast cancer (OR=1.65, 95%CI: 0.98-2.78, p=0.05; OR=1.72, 95%CI: 1.01-2.92, p=0.04). Conclusion: The results of present study indicated that among the five TP53 polymorphisms investigated, the p.R72P polymorphism, and the RP-A1A1 and RP-GG genotype combination contribute to breast cancer susceptibility in North Indians.

Background: Areas of Iran have among the highest incidences of esophageal cancer in the world. Definitive chemo-radiotherapy (DCRT) is used for locally advanced esophageal cancer and for inoperable tumors asan alternative to surgical treatment. Materials and Methods: This retrospective study was conducted in North-West Iran 2006-2011, including 267 consecutive patients with non-metastatic esophageal cancer. Eligible inoperable patients were treated with DCRT or definitive radiotherapy (DRT) alone. Radiotherapy (RT) was delivered at 1.8-2 Gy/day for five consecutive days in a given week. Chemotherapy (CT) consisted of cisplatin and 5-fluorouracil. Results: The median survival was 12.7 months with 1, 3 and 5 year survival rates of 55%, 18% and 11%, respectively. On univariate analysis, relations with age at diagnosis (p=0.015), N-stage (p=0.04), total dose of RT (p=0.001), fraction (p<0.001), Gap status (p=0.025), chemotherapeutic regimens (P=0.027), and 5-Fu $Mg/m^2$ (P=0.004) were apparent. Comparing DCRT to DRT, there was a significant difference in survival. Multivariate analysis was performed for comparison between DCRT and DRT showed significant association with age group ${\geq}65$ to <65 (P=0.02; OR: 1.46), the total RT dose (Gy) ${\geq}50$ to <50 (P=0.01; OR: 0.65) and the fraction group ${\geq}25$ to <25 (P=<0.001; OR: 0.54). Conclusions: The survival rates of esophageal cancer treated with DCRT in North West of Iran is poor; therefore, early detection and improved treatment methods, with clinical trials are a high priority.

Objective: To establish the prevalence and distribution profile of esophageal squamous cell carcinomas (ESCCs) over a 22-yr period in North China. Methods: Using endoscopy for primary diagnosis and histological analysis for the further confirmation, a total of 74,854 ESCC patients aged 20-89 between January 1985 and December 2006 were investigated to analyze the epidemiological profile including prevalence rates, distribution of age-of-onset, gender and geographical area of ESCC in Luoyang, the highest incidence area of North China. Results: A total of 4092 cases of ESCC were finally diagnosed among 74,854 patients who had their first endoscopies. The prevalence among males was higher than that among females (p<0.01), resulting in an overall male:female OR of 1.2 (95%CI, 1.2-1.3). The prevalence in rural areas was higher than in urban areas (p<0.01), resulting in an overall rural:urban OR of 2.6 (95%CI, 2.4-2.9). The rural:urban ORs and the 95% CI increased continuously from 2.6, 2.3-3.0 to 2.7, 2.2-3.3, respectively, for 4 consecutive periods during the 22-yr study period. Moreover, the median age of onset among females was higher than that among males (p<0.01). For both sexes and in both areas, the prevalence rates declined and the median age of onset rose for 4 consecutive periods in the 22-yrs time frame (p<0.01). Conculsions: These data reveal the epidemiological profile of ESCC in the area of North China, and suggest that urban areas and rural people account for a growing proportion of the ESCC patients although the prevalence of ESCC significantly declined and the median age-of-onset postponed over the 22-yrs period. Moreover, the prevalence status of ESCC in rural areas also underlines the need for public health initiatives aimed at reducing risk factors of this fatal disease.

This study investigates the accuracy of short-term ocean predictions during the development of ocean stratification for the Korea Meteorological Administration (KMA) Global Seasonal Forecast System version 5 (GloSea5) as well as the effect of atmosphere-ocean coupling on the predictions through a series of sensitive numerical experiments. Model performance is evaluated using the marine meteorological buoys at seas around the Korean peninsular (KP), Tropical Atmosphere Ocean project (TAO) buoys over the tropical Pacific ocean, and ARGO floats data over the western North Pacific for boreal winter (February) and spring (May). Sensitive experiments are conducted using an ocean-atmosphere coupled model (i.e., GloSea5) and an uncoupled ocean model (Nucleus for European Modelling of the Ocean, NEMO) and their results are compared. The verification results revealed an overall good performance for the SST predictions over the tropical Pacific ocean and near the Korean marginal seas, in which the Root Mean Square Errors (RMSE) were $0.31{\sim}0.45^{\circ}C$ and $0.74{\sim}1.11^{\circ}C$ respectively, except oceanic front regions with large spatial and temporal SST variations (the maximum error reached up to $3^{\circ}C$). The sensitive numerical experiments showed that GloSea5 outperformed NEMO over the tropical Pacific in terms of bias and RMSE analysis, while NEMO outperformed GloSea5 near the KP regions. These results suggest that the atmosphere-ocean coupling substantially influences the short-term ocean forecast over the tropical Pacific, while other factors such as atmospheric forcing and the accuracy of simulated local current are more important than the coupling effect for the KP regions being far from tropics during the development of ocean stratification.

Pacific bluefin tuna (Thunnus orientalis) is one of the commercially important species in Korea as well as other countries of the North Pacific. Korean offshore large purse seine fisheries targeting small pelagic fishes such as chub mackerel have caught T. orientalis temporarily in the east of Jeju Island. The catch of T. orientalis in March through June occupied approximately 60% of the total. The monthly catch around Jeju Island from 2004 to 2013 showed a negative correlation (r = - 0.755, p < 0.01) with the seawater temperature at 50 m and had a significant positive correlation (r = 0.856, p < 0.01) with the Pacific Decadal Oscillation Index (PDOI). The highest catch and catch per unit effort (CPUE) of T. orientalis around Jeju Island occurred either when the seawater temperature ranged between 15 and $16^{\circ}C$ at 50 m or when the catch was taken near the frontal area where two water masses from offshore and coastal areas collide. The length of T. orientalis caught around Jeju Island from 2004 to 2013 ranged from 19 to 193 cm in fork length (FL). The time series of the monthly mean FL of T. orientalis had a negative correlation (r = - 0.592, p < 0.01) with the seawater temperature at 50 m and had a significant positive correlation (r = 0.668, p < 0.05) with PDOI.

이 연구는 북한이탈주민지원정책의 변천과정에 따라 북한이탈주민을 위한 비영리단체의 등장배경을 살펴보고 비영리단체의 특성과 역할에서 나타나는 문제점을 파악하는 것이다. 1990년대부터 북한이탈주민의 증가와 함께 다문화사회의 진입으로 인한 국내사회환경변화 등 다양한 환경요인으로 민간단체들이 급증하였다. 하지만, 단체의 제도적 형식조차 갖추지 않은 단체도 있으며 사업목적과 다른 활동을 하는 경우도 있었다. 또한 서울 거주 북한이탈주민 전체의 수는 25.5%에 비해 북한이탈주민관련단체는 서울지역에만 83%를 차지하고 있다 보니 성향이 비슷한 일부 단체들의 과도한 영역경쟁으로 불법과 편법의 온상으로 변질된다는 목소리가 높을 수밖에 없다. 단체의 유형에서는 실질적으로 북한이탈주민에게 필요한 취업이나, 미래의 주역이 될 청소년의 통일의식함양을 위한 통일교육 분야는 미미하게 성장하고 있었으며 이러한 결과는 단체라는 활동은 사회의 한 구성원으로 권리와 책임의식을 가져야 하며 또한 문제 개선을 위한 정부의 실질적인 노력도 필요하다는 것을 보여주고 있다.
