In this article, I examined the conflict of youth reflected in Bae Bong Ki's plays based on theory of 'conflict'. Bae Bong Ki has been questioning the 'youth rights' in determining the content of performances, along with 'the magnetic field of college entrance examination' where most of the youth feel under huge pressure in his play. In the and , I focused on the students with the highest grade and the students with the lowest grade in the context of university entrance examination. Students who are struggling to keep the grades up are captured in this play as the educational reality of adolescents in distress. The situation of the top and bottom students is different, but both top and bottom students were too stressful to go to school. And 'the rights of the youth in deciding the content of the performance' in was a difficult topic because it collides with the right for the teacher to educate. It is expected that many plays will be created reflecting the conflict of youth in the future, and youth theater as well as discussions upon it will be enriched.

담수와 염수가 적절히 혼합되어있는 만에서는 굴과 가리비 미역 등의 양식업이 활발히 이루어지고 있다. 이러한 바다생물 특히, 미역의 경우는 염분농도가 13psu 이하의 상태가 장시간 유지될 경우 심한 피해를 입는다는 보고가 있다. 그러므로 만에서의 염분분포 파악은 자연환경의 적절한 활용 및 자연재해의 예방적 측면에서 매우 중요하다고 사료되어진다. 본 연구에서는 만에서의 염분분포를 파악하기 위하여 위성영상을 활용하였다. 위성영상은 현지관측이 어려운 홍수기에도 데이터 취득이 가능하며, 대상 지역 전체를 한눈에 볼 수 있는 면분포를 제공한다는 장점이 있다. 본 연구에서 수행한 구체적인 방법은 다음과 같다. 첫째, 위성영상과 탁도와의 높은 상관을 이용하여 위성영상을 탁도 분포로 변환하였다. 둘째, 현지 관측으로부터 얻은 염분과 탁도와의 상관관계를 이용하여 탁도 분포를 염분 분포로 변환하였다. 끝으로, 본 추정수법은 현지관측결과와의 검증을 통하여 타당성을 입증하였다. 결론적으로, 본 수법은 현지관측에 드는 비용절감과, 관측 데이터가 부족한 홍수기의 자연현상 파악등에 그 활용 가치가 있다고 확인되었다.

High-performance liquid chromatography (HPLC) screening method revealed that a propolis product marketed as a functional food contained an undeclared substance similar to tadalafil, the active ingredient of the prescription drug Cialis$^{(R)}$ approved for the treatment of male erectile dysfunction. In order to identify the illegal additive, the propolis product was extracted with methylene chloride, and the extract was purified further using semipreparative HPLC. The chemical structure of the isolated substance was elucidated based on IR, LC/MS-ESI, and $^1H$- and $^{13}C$-NMR spectroscopy, which showed the characteristics similar to tadalafil. The only difference was the substitution of the methyl group at the piperazinedione ring of tadalafil to the amino group of the identified illegal additive.
