Korea Department of Defense has been developing Link-K, Korean Joint Tactical Datalink, to support their independent joint operations and trying to enlarge the scope of Link-K tactical message delivery to nodes in IP based tactical networks for sharing situation awareness more broadly. A Link-K tactical message size is too small to fit into an IP packet, inefficiently wasting most of the IP packet space of the low bandwidth IP-based tactical networks. This paper proposes a new Link-K tactical message aggregation and delivery method when tactical messages need to be sent to some nodes located at IP-based tactical networks. With numerical analysis and OPNET simulation studies, we prove the effectiveness and efficiency of the proposed method.

Objective: Few studies have examined the impact of chronic diseases on populations using a comprehensive health-related quality of life (HRQOL) in Korea. We assessed HRQOL of patients with 16 common chronic diseases. Methods: We interviewed patients with chronic diseases (n=980) and healthy control (n=288) using two HRQOL measurements: Korean Medical Outcome Study Short Form-36 (KSF-36) and Korean EuroQol-5 Dimensions (KEQ-5D), and questions on sociodemographic and clinical characteristics. Results: Each illness had a distinctive profile. Among disease groups, the KSF-36 global health score was highest in DM and lowest in fibromyalgia. The KSF-36 physical component summary score was highest in DM and lowest in osteoarthritis. The KSF-36 mental component summary score was highest in hypertension and lowest in fibromyalgia. The KEQ-5D utility score was highest in DM and lowest in fibromyalgia. The KEQ-5D visual analog score was highest in DM and lowest in liver cirrhosis. In correlation analysis, the KSF-36 physical component summary, mental component summary and five domains in KEQ-5D were well correlated with each others. Conclusion: Health related quality of life in Korean patients with chronic disease is lower than healthy control. Patients with hypertension and DM registered the two highest scores in global health but patients with fibromyalgia reported the worst health experience in global health. We can compare the profiles of the groups and determine the relative impact on the patients of the various diseases and these data will provide a baseline of the current health related quality of life of individuals suffering from a variety of conditions.

A cost effective analysis was performed for comparing leflunomide + methotrexate. etanercent monotherapy and etanercept + methtrexate for 6 months. For the patients with methotrexate-resistant RA, ACR20 data were extracted from the published clinical trials searched from Pubmed. The direct medical cost was estimated based on ACR guideline and Korean National Health Insurance reimbursement. Combination therapy of etanercept + methotrexate was found to be more cost-effective than etanercept monotherapy, which meant it was a better therapeutic strategy for methotrexate-resistant RA.
