The purpose of this study is to present underlying principles and criteria for designing and developing National English Ability Test (NEAT). To this end, this study presents 5 principles (i.e., Connection, Authenticity, Interactiveness, IBT Compatibility, Washback Effectiveness) which play guiding and controlling roles in developing and selecting item types appropriate for the listening and the reading test of NEAT derived from test usefulness (Bachman & Palmer, 1996). Also, it proposes 4 criteria (i.e., Complementarity, Integration, Pivotality, and Hierarchicality) which function levering roles in designing and developing the two tests of NEAT on the basis of the empirical data of the item analyses of Foreign (English) domain of College Scholastic Ability Tests (2005~2010 school year). Finally, it discusses some implications and applications of the principles and the criteria to a theoretical blueprint for establishing an item developing system and a test implementation system, setting up the criteria of validating item types, designing a modular type of test specifications, and specifying a complementary type of test specifications for the two ability-level listening and reading tests (the 2nd and the 3rd rank) of NEAT.
초지관리용 2종 복합비료를 개발토자 시제품(N-P2O5-K2O-MgO-B2O3: 14-10-12-3-0.2)을 일반단비와 공시하여 비효를 비교검토하였다. 대상초지로는 새로 조성된 겉뿌림 혼파초지(orchardgrass, tall fescue, Kentucky bluegrass 및 ladino clover) 및 기존의 겉뿌림 단파초지(orchardgrass 우점초지)를 공시장소로하여 2년간 시험을 수행하였다. 1보에서는 토양

The purpose of this study is to evaluate the corrosion protection properties of Zn/Sn metal spray method according to the contents ratio of Zn and Sn by CASS test. Also, the corrosion protection life of Zn/Sn metal spray method is evaluated by the comparing between the corrosion properties of Zn metalizing method and Zn/Sn metal spray method using CASS test. As a result, it was confirmed that the optimum content ratio of Zn/Sn in metal spray method is 60:40(65:35) (Zn : Sn volume ratio) in aspect of corrosion protection properties and construction properties. Also, it was confirmed that the Zn/Sn metal spray method had more than 3 times of corrosion protection properties cmparing the Zn matalizing method.
