Survey data were collected and analyzed using a structural equation model(SEM).Results: Perceived social support had a significantly positive effect on PA(b = 0.14, p < 0.01) and QoL(b = 0.28, p < 0.001) while decreasing loneliness(b = —0.55, p < 0.001). PA had a significant positive effect on QoL(b = 0.12, p < 0.01), and loneliness had a negative effect on QoL(b = —0.37, p < 0.001). Loneliness mediated the relationship between perceived social support and QoL.Conclusion: The SEM results of the current study support the proposed model that explained the interrelationships among perceived social support, loneliness, PA, and QoL among active older adults in South Korea. These findings suggest the importance of incorporating social support mechanisms for PA interventions in order to enhance QoL. The findings of this study can help create more effective health and physical education programs for the older generations in South Korea to enhance their QoL.展开更多

An analysis demonstrates that the movie and television industry of South Korea is one of the most essential factors to attract the potential tourist from China. South Korean Pop culture is directly affecting rather the image of South Korean as a tourist destination than tourists＇ purchasing. And the paper suggests a set of ＂4S＂ strategy for South Korean to combine the elements of South Korean movies with those of tourism, so as to create an industrial development pattern characterized as ＂movies ＋ tourism＂.展开更多

METHODS： We conducted a population-based, large- scale case-control study including 2213 GCs, 1829 CRCs, and 1699 controls. Null and non-null genotypes of GSTM1 and GSI-F1 were determined using realtime PCR. RESULTS： The null genotypes of GSTM1 and GSTT1 were not significantly associated with elevated risk of gastric （OR = 1.070, 95% CI = 0.935-1.224; OR = 1.101, 95% CI = 0.963-1.259, respectively） or colorectal cancer （OR = 1.065, 95% CI = 0.923-1.228; OR = 1.041, 95% CI = 0.903-1.200, respectively）. The frequency of the combined null GST genotype was not different between the two cancer groups and controls. Moreover, smoking, drinking, and age did not modify the association between these genotypes and the risk of gastric or colorectal cancer. CONCLUSION： GSTM1 and GSCI-1 null genotypes were not associated with increased risk of GC or CRC in Koreans.展开更多

This is the first report of the genus from the Korean Peninsula, expanding its geographical range to the eastern Sino-Korean Block. The new species also occurs in the Xiazhen Formation （Upper Ordovician, Katian） at Zhuzhai in the South China Block. Amsassia koreanensis is the smallest species of this modular genus, having a maximum module diameter of 0.28 ram. Module increase is by bipartite, tripartite and quadripartite types of longitudinal axial fission, but unlike other species of the genus, quadripartite fission is common. The types of fission are comparable to those in some Tetradiida （now Prismostylales, florideophycean rhodophyte algae）, although the processes of fission are different. The distribution of A. koreanensis further strengthens the biogeographical connection between the Sino-Korean and South China blocks, suggesting that these two paleocontinents were located closer together during the Middle to Late Ordovician than previously speculated.展开更多
