Harmful algal blooms (HABs) can be controlled by mitigation using prevent methods of incoming eutrophication from pollution sources and restoring environmental condition using physical, chemical and biological control methods. Polymerized mesoporous zeolites (pMZ) was simply prepared by acid treatment and polymerization of ethylene diamine(ED), which evaluated as adsorbents for the removal of chlorophyll A and microcystin-LR from aqueous solutions. The effects of treatment times on the pore structure of the pMZ were studied as well as the effects of different acids which were also investigated during synthesis. The pMZ samples were characterized by nitrogen full isotherms, XRF analysis, image (SEM and TEM) analysis and FT-IR spectroscopy. The pMZ prepared using AFHS (ammonium hexafluorosilicate) had higher meso-pore volume, and surface area. So, polymerized mesoporous zeolite is based on AHFS treated zeolite for surface modification. The adsorption ability of pMZ for chlorophyll A and microcystin-LR which are index of algae bloom and evaluated the influence of modification materials. In addition, the adsorption isotherm were evaluated using Langmuir, Freundlich and Sips equations. The adsorption capacity resulted that the pMZ could removal the algae bloom indicators from aqueous solution at the modification of zeolite and different adsorption capacity were examined to explain the adsorption experiment. MZ is able to adsorb the chlorophyll A 29 mg/g. pMZ is able to remove 80% of microcystin-LR in 25 min.

최근 우리나라 동해안에는 너울성 고파의 반복적인 내습이 빈발하고 있다. 외해에서 발생하여 갑작스런 내습과 함께 인명과 시설에 피해를 끼치는 너울성 고파를 대상으로 그 처오름 특성을 확인하였다. 파랑 스펙트럼의 형상을 정량화하기 위해 스펙트럼 형상모수 $Q_p$, ${\varepsilon}$, ${\nu}$ 등을 도입하여 이들 모수들과 유의파고 및 첨두주기와의 상관관계를 파악하였고, MIKE21 BW 모듈을 사용하여 완경사 해안에 대한 처오름 수치실험을 수행하였다. 파고와의 상관관계가 가장 낮은 $Q_p$를 추가적인 형상 변수로 채택하여 파랑 스펙트럼의 형상 변화에 따른 처오름 높이의 변화와 특성을 확인하였다. Recently the large-height swell-like waves generated in the eastern coast of South Korea have been observed frequently. The characteristics of the runup and overtopping of the large-height swell-like waves formed in deep water and attack the coast, causing damages to both lives and facilities have been studied. The correlation between spectral shape parameters and significant wave height has been investigated by analyzing long term wave spectrum data. Numerical runup experiments using MIKE21 BW Module were performed with $Q_p$, additional shape parameter, and identified the variations and characteristics of runup heights with respect to the variations of spectral shape.

The application and proliferation of cyber-physical system(CPS) based on the boundless connection between the physical and cyber world is expected to bring about innovative changes in various business fields. The purpose of this study is to develop a strategic design framework for new business incubation and to suggest its practical approach through exploratory studies on cyber physical system and business model. To do this, by combining design thinking and business model and by layering the attributes of CPS, this research first established an integrated approach based on literature studies, and suggested a strategic framework to examine the implemental applicability through a case study. The framework has a three-phase structure: Initiation, Incubation and Implementation for a stepwise design approach, and presents a practical model of business concept generation through CPS attribute conversion in conjunction with the business model elements. This suggests an advanced guideline for new CPS business incubation in that it provides differentiated viewpoints of product-system and new convergence opportunities integrated with the strategic business elements.

최근 문화 콘텐츠 기술(Culture Technology)이 새롭게 대두되고 있다. 이 중에서도 지능형 음악분수에 대한 연구는 아직 시작단계에서 연구가 이루어지고 있다. 음악분수의 자동 시나리오 생성을 위한 기반 기술로 음악과 분수의 동기화를 최적화하기 위해서는 음악적 특성 중에 하나인 비트(Beat)를 분석해야 한다. 본 논문에서는 음악적 표현 최적화를 위해 Beat Tracking 알고리즘을 기반으로 음악 특징 검출 기법에 대한 연구를 진행하였다. 이를 수행하기 위하여 랜덤 하게 들어오는 음원에 대하여 주파수 대역별로 음원을 분석하고 기존의 알고리즘에서 클라이막스 부분에서 감쇄 되는 비트 성분을 추출하여 실제 비트를 보정하였으며 시뮬레이션을 통해 이를 입증하였다.
