Objectives: The aim of this paper is to analyze the heath factors for longevity index of survival rate in Korean centenarians, which contribute to longevity. Methods: The subjects of this paper included 996 centenarians in 276 regions of Korea that the data in this study was collected from the National Statistical Office, Republic of Korea in 2005. This paper that proposes indicators as follow: The ratio between the longevity index above 100 years old (100LI) and the survival rate above 65 years old (65SR): 100LISR. The study that examined the longevity factors that between 100LISR and health factors. Results: The results of this study showed that Gyeryong City (23 per 10,000 above 65 years old) included the most of 100LISR in Korea, followed by Cheju Island. The regression showed that significant predictors for longevity (100LISR) were non-drinking, non-smoking, garlic and root vegetable and elderly people are suffering serious health problems, they need caregivers for elderly care (R-Sq(%)=83.9, P=0.001). The correlation showed that significant factors as longevity were Sulfur dioxide (r=-0.677, p=0.004). Conclusion: The implications of this study are that longevity is to be fostered by promoting healthy behaviors of elderly and by inventing various policies to mitigate the environmental pollution.

Osteoporosis in gastric cancer patients is often overlooked or even neglected despite its high prevalence in these patients. Considering that old age, malnutrition, chronic disease, chemotherapy, decreased body mass index and gastrectomy are independent risk factors for osteoporosis, it is reasonable that the prevalence of osteoporosis in gastric cancer patients would be high. Many surviving patients suffer from back pain and pathological fractures, which are related to osteoporosis. Fractures have obvious associated morbidities, negative impact on quality of life, and impose both direct and indirect costs. In the era of a >55.6% 5-year survival rate of gastric cancer and increased longevity in gastric cancer patients, it is very important to eliminate common sequelae such as osteoporosis. Fortunately, the diagnosis of osteoporosis is well established and many therapeutic agents have been shown to be effective and safe not only in postmenopausal females but also in elderly males. Recently, effective treatments of gastric cancer patients with osteoporosis using bisphosphonates, which are commonly used in postmenopausal woman, were reported.

To evaluate the factors that determine the transmission level of vivax malaria using vectorial capacity, entomological surveys were conducted from .lune to August, 2000. From 6 nights of human-bait collection in Paju, the human biting rate (ma) was counted as 87.5 bites/man/night. The parity of Anopheles sinensis from human baiting collections fluctuated from 41% to 71% (average 48.8%) of which the rate gradually increased as time passed on: 35.2% in Jun. ; 55.0% in July; 66.2% in Aug. From this proportion of parous, we could estimate the probability of daily survival rate of An. sinensis to be 0.79 assumed with 3 days gonotrophic cycle and the expectancy of infective life through 11 days could be defined as 0.073. Blood meal analysis was performed using ELISA to determine the blood meal source. Only 0.8% of blood meals were from human hosts. We could conclude that An. sinensis is highly zoophilic (cow 61.8%) Malaria is highly unstable (stability index < 0.5) in this area. From these data, vectorial capacity VC) was determined to be 0.081. In spite of a high human biting rate (ma), malaria transmission potential is very low due to a low human blood index. Therefore, we could conclude that malaria transmission by An. sinensis is resulted by high population density, not by high transmission potential. For this reason, we need more effort to decrease vector population and vector-human contact to eradicate malaria in Korea.
