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.

The purpose of this research is to analyze the European paradigm of health investment and its implication. Conventional content analysis of WHO/EU(/EC)/European countries' policy data, and articles shows that the European paradigm of health investment is consist of the basic and extended models, twelve life-course-based health investment policies, and SROI evaluation method. The analyses and discussion points provide policy implications for making virtuous cycle of Korean sustainable healthcare system with economic development in the post Covid-19 era.

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.
