본 연구는 돼지 수정란의 체외 성숙 및 체외 배양액의 retinol 첨가 효과를 규명하기 위하여 체외 성숙 및 체외 배양액에 retinol을 첨가하여 수정란의 체외 발달에 미치는 영향을 구명하고자 수행되었다. 체외 성숙 배양액에 retinol을 첨가한 결과 성숙율은 으로 각 처리구 간의 유의적인 차이가 없었다(p>0.05). 체외 수정 후 배반포로의 발달율은 첨가구에서 의 발달율을 나타내어 타 처리구에 비하여 유의적으로(p<0.05) 높게 나타났으며,

The purpose of this study is to identify the factors affecting intention to use blog. Especially, The factors such as subject norm, perceived enjoyment, self-efficacy are individual characteristics to identify in this study. Also, Technology Acceptance Model(TAM) that has been widely used to predict the end-user's acceptance of a new technology is adopted for the study. A model with individual characteristics (subject norm, perceived enjoyment, and self-efficacy) and Technology Acceptance Model variables (perceived ease of use, and perceived usefulness) were used to explain intention to use blog. The suggested model has been empirically tested with questionaries. The result shows that individual characteristics such as perceived enjoyment and self-efficacy and factors of technology acceptance model have significant impact on users' intention using blog.

According to Korea was re-elected as ICAO council member state at the 35th session of the assembly, there are more contributions and roles of international aviation society. Being developed technology and grown international transportation, world is focusing to aviation safety, Safety Management System(SMS) is systematic approach to manage risks caused by human and organizational factors. ICAO is specified that 'As of 24 November 2005, certified aerodrome shell have in operation a safety management system.' at Annex 14 to implement it airports as a first step. This study introduced SMS principle, analysed SMS's of advanced states and developed appropriate Korean Aerodrome SMS Model in our cultural and industrial circumstances.
