본 연구는 적충복합보에 있어서의 층간분리현상을 추적하는 기법을 소개하고 있다. 이 기볍에서는 충간분 리된 보와 층간분리되지 않은 보와의 응답차이를 최대화하도록 조화운동의 가력올 보위별로 최적화한다.2개 층의 알루미늄 보에 대하여 수치해석을 수행하였으며， 계측 및 보의 형태에 따른 노이즈를 고려하였다. 층간 분리를 모텔링하기 위하여 스웹함수를 사용하였으며 층별복합판 이론에 기본한 유한요소법을 이용하여 해석 하였다.

스마트디바이스의 급속한 발전과 함께 디지털미디어적인 콘텐츠 소비속도가 매우 빨라지고 있다. 그로 인하여 다양한 이야기가 필요하게 되었고, 이야기를 창작하기 위해 문화 원형들의 재현이 많아지고 있다. 원형은 집단적 무의식 안에 내재된 행동이며, 상상과 경험에서 오는 전 형적인 본보기인 만큼, 콘텐츠에 재현되는 원형이 왜곡되거나 변질되는 현상들은 민족 전통의 정체성까지도 위협할 수 있다. 본 논문은 원형 재현에 성공한 서양 콘텐츠와 원형재현에 실패 한 국내 콘텐츠를 분석하고, 문화원형 재현의 실패에 따른 양상들을 파악하여, 향후의 스토리텔 링 방법론을 고찰해 보았다.

To study the effects of an urease inhibitor, N-(n-butyl)-thiophosphoric triamide (NBPT), and a nitrification inhibitor, dicyandiamide (DCD), on nitrogen losses and nitrogen use efficiency, urea fertilizer with or without inhibitors and slowrelease fertilizer (synthetic thermoplastic resins coated urea) were applied to direct-seeded flooded rice fields in 1998. In the urea and the urea+DCD treatments, NH4 + -N concentrations reached 50 mg N L-1 after application. Urea+NBPT and urea+ NBPT+DCD treatments maintained NH4 + -N concentrations below 10 mg N L-1 in the floodwater, while the slow-release fertilizer application maintained the lowest concentration of NH4 + -N in floodwater. The ammonia losses of urea+NBPT and urea+NBPT+DCD treatments were lower than those of urea and urea+DCD treatments during the 30 days after fertilizer application. It was found that N loss due to ammonia volatilization was minimized in the treatments of NBPT with urea and the slow-release fertilizer. The volatile loss of urea+DCD treatment was not significantly different from that of urea surface application. It was found that NBPT delayed urea hydrolysis and then decreased losses due to ammonia volatilization. DCD, a nitrification inhibitor, had no significant effect on ammonia loss under flooded conditions. The slow-release fertilizer application reduced ammonia volatilization loss most effectively. As N03 [-10] -N concentrations in the soil water indicated that leaching losses of N were negligible, DCD was not effective in inhibiting nitrification in the flooded soil. The amount of N in plants was especially low in the slow-release fertilizer treatment during the early growth stage for 15 days after fertilization. The amount of N in the rice plants, however, was higher in the slow-release fertilizer treatment than in other treatments at harvest. Grain yields in the treatments of slow-release fertilizer, urea+NBPT+ DCD and urea+NBPT were significantly higher than those in the treatments of urea and urea+DCD. NBPT treatment with urea and the slow-release fertilizer application were effective in both reducing nitrogen losses and increasing grain yield by improving N use efficiency in direct-seeded flooded rice field.field.
