The purpose of this study is to assess the effects of the separation of prescribing and dispensing in Korea and to find how civilians' usage behaviors on medical institutes such as hospital, clinics, drugstore, and community health center are changed due to the policy. To examine the differences of usage behaviors, this study used a before-after design. Using self-administered questionnaires, this study performed survey from June 26 to August 1, 2000. Chi-square test and generalized logit model was utilized in each observation period. Based on the results of each observation period, this study evaluated the effects of the policy. On the basic finings, most civilians did not agree to the separation policy regardless of both observation periods. However, after the separation, civilians' behaviors seemed to be modified as the policy maker had intended. Most of civilians purchased their drugs from pharmacists after receiving physicians' prescriptions. Specifically, males and elder persons had the exactly same behaviors as the intended utilization behaviors. All study subjects agreed to the basic purpose of the policy for the purpose of the reduction of drug abuse and misuses. The implications of this study are two fold: First, how civilians' short-term inconvenience caused by the policy should be alleviated without interrupting well-established usage patterns. Second, a special attention to the elderly is needed.
On a Background of the Existence of Multi-variable Link Invariants
Nagasato, Fumikazu,Hamai, Kanau Department of Mathematics 2008 Kyungpook mathematical journal Vol.48 No.2
We present a quantum theorical background of the existence of multi-variable link invariants, for example the Kauffman polynomial, by observing the quantum (sl(2,$\mathbb{C}$), ad)-invariant from the Kontsevich invariant point of view. The background implies that the Kauffman polynomial can be studied by using the sl(N,$\mathbb{C}$)-skein theory similar to the Jones polynomial and the HOMFLY polynomial.
