It is difficult to apply a Software Process Certification to small scale project, because of much activities and documents for manage project and guarantee the qualities in small manpower. This paper presents optimized Software Process Certification Model for small scale software development, a combine Scrum with essential elements of NIPA's(National IT industry Promotion Agency) SP-Certification model. The proposed model defined minimum Activities and Documents for SP Certification. The model that I showed consists of 16 Processes and 58 Activities, and 39 Artifacts are created. As a result of having compared proposed model with a Standard Process of Small Business, I confirmed that a small scale project's burden reduced because Activity decreased 38% and Document decreased 20%. In order to verify the validity of the proposed model, applied•제1저자, 교신저자 : 송인오 •투고일 :
In this study, cinnamon essential oil (CEO) was formulated as emulsifiable concentrate (EC) and a granule. For the evaluation of their negative effects on the ecosystem, acute toxicities against Cyprinus carpio was determined in a static condition. The formulations were made using CEOs extracted by 3 different methods (steam distillation (SD), solvent extraction and supercritical fluid extraction (SFE)) and were tested to obtain LC 50 values. Among the ECs, EC including CEO extracted by SFE showed highest acute toxicity against C. carpio. Among the granules, a granule including CEO extracted by SD showed highest acute toxicity against C. carpio. Nevertheless, LC 50 of EC and a granule formulation with CEOs was higher than toxicity level III of pesticide standardized by Korea rural development administration. These results were similar to those using zebrafishes. Chronic toxicities were not found for 45 days in zebrafishes until 500 µgL −1 level of EC formulation including CEO obtained by the SD. Based on these results, EC formulation of CEOs may be considered to be used as environmental-friendly natural insecticides in accordance with the standards.
