  • National Agricultural Pesticide Risk Analysis (NAPRA) WWW 시스템 (http://pasture.ecn.purdue.edu/${\sim}napra$)은 각기 다른 영농방법이 지표수질, 유사, 그리고 지하수질에 미치는 영향을 평가하기 위하여 개발되었다. 이 NAPRA WWW 시스템은 Total Maximum Daily Loads와 같은 수질 요건을 만족시킬 수 있는 최적영농 방법이 무엇인지 찾는데, 그리고 수질측면에서 취약한 지역을 찾아내는데 매우 효율적인 시스템이다. 이 NAPRA WWW 시스템을 이용하여 미국 인디애나주의 수계에 대해서, NAPRA 모의 Nitrogen과 Atrazine 결과를 실측치와 비교하였다. 18개 수계에 대해서 NAPRA 예측 질소값과 실측 질소값을 비교한 결과 $R^2$ 값은 0.51이고, 6개 수계에 대해서 NAPRA 예측 Atrazine값과 실측값을 비교한 결과 $R^2$ 값은 0.87이었다. 이 연구에서 보여지는 바와 같이 NAPRA WWW 시스템은 수계내에서 질소와 Atrazine에 따른 오염지역을 찾아내는데 효율적으로 사용될 수 있는 시스템이다.

  • Many features of the Single Field version have been enhanced to provide user friendly interface. The County/Watershed version of NAPRA WWW system was further enhanced. The newly developed Web GIS version is an ideal tool for novice users, such as farmers, to simulate the effects of agricultural management for their farms because of its easy-to-use Web GIS interface. The NAPRA WWW system provides an easy to use WWW interface and uses spatial and relational databases to simplify the process of preparing model files. Thus, the NAPRA WWW systems now can be effectively used for nutrient management as well as pesticide management to identify the least impact agricultural management practices.

  • Livestock manure is an important source of nutrients for crop production. However, farmers typically do not know the exact nutrient values for livestock manure. In many instances, manure has been viewed as a waste, and as a result it is applied close to the source resulting in over application of nutrients. Thus, the goal of nutrient application has often been applied to reduce the application expense rather than to maximize crop income. This results in wasted money and potentially negative impacts on water quality. Several livestock manure management scenarios were created based on agronomic nutrient requirements using the Utilization of Animal Manure as a Plant Nutrient (AMANURE) software to investigate water quality impacts with the National Agricultural Pesticide Risk Analysis (NAPRA) WWW modeling system. Application of manure at agronomic rates can result in high nitrate-nitrogen losses for some soil types, especially when applied in late fall. The application of manure at an agronomic rate does not necessarily equate to adequate water quality protection, and farmers must take care applying manure at agronomic rates, because nitrate-nitrogen loss potential varies spatially and temporarily. Nutrient loss probability maps for Indiana at 5%, 10%, 25%, and 50% values were created to demonstrate potential water quality impacts when livestock manure is applied to cropland at agronomic rates. The NAPRA WWW system coupled with AMANURE can be used to identify site-specific livestock manure management plans that are environmentally sound and agronomically appropriate.

  • A newly-structured Korean pharmacist license exam has been launched in 2015, reflecting upon the changes in the pharmacy curriculum from a 4 year program to a 6 year program in 2009. In order to provide new ideas to ensure that the new exam is one of the most effective pharmacist evaluations that have taken place thus far, this study was done to compare the pharmacy exams in Korea and Canada. One of the major differences noted between the two countries' exams is that along with paper based MCQ portion of the exam, Canada's exam also includes a performance-based section, known as OSCE, which the Korean Pharmacy Exam (KPE) does not have. Furthermore, with the MCQ portion of the exam, the Canadian exam asks about 300 questions, with 450 minutes of test time allocated and taken during a period of two consecutive days, the KPE asks 350 questions, with 325 minutes of test time allocated in one day. Although, similarly, many of the questions in both exams place emphasis on clinical or patient care, Canada's exam puts significantly more emphasis (50.5% of exam questions) on these types of questions than Korea (29.7% of exam questions). However, this percentage does not reflect the exact weight placed for the specific areas of knowledge it requires to answer these questions, since the types of questions asked in this section in Canada could be placed in another section on the KPE. Canada's exam also has more questions (10% +150 questions for BC) on the topics of law and ethics compared to the KPE (5.7%). The reason for this may be that the Canadian society puts emphasis on the legal and ethical duties of pharmacists as a leader. However, since each country is unique in their social, economical, and cultural points of view, comparing the KPE to the Canadian licensing exam and applying these differences to the new KPE may not be appropriate. One last thing to consider is that, as WHO/FIP mentioned, in good pharmacy practice, continually updating and developing an appropriate pharmacy exam with consideration of societal changes, is key to success in developing the scope of practice for current and future pharmacists.
