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.

파랑 스펙트럼 형상에 따른 처오름 특성

박승민,윤종태,정원무,Park, Seung Min,Yoon, Jong Tae,Jeong, Weon Mu 한국해안해양공학회 2014 한국해안해양공학회 논문집 Vol.26 No.6

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.

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.

한국 정부의 고령친화산업 활성화 정책의 가능성과 한계

박승민(Park Seung Min) 한국노년학회 2017 한국노년학 Vol.37 No.1

본 논문의 목적은 한국 정부가 인구 고령화 문제에 대응하고자 저출산 고령사회위원회를 통해 제시한 고령친화산업 활성화 정책 분석을 통해 한국의 고령친화산업 발전을 위한 함의를 제공하는 것이다. 이를 위해 제1-3차 저출산 고령사회기본계획에 제시된 고령친화산업 활성화 정책 중에서 한국 노인의 대표 3대 고통 완화와 직접적으로 관련된 정책을 분석 자료로 하여 그것의 구체적 내용, 공통 핵심 논리와 그 타당성을 분석해 정책적 이론적 함의를 도출했다. 분석 결과, 제1차 기본계획은 경제적 빈곤 문제 완화, 제2차 기본계획은 신체적 건강 문제 완화, 제3차 기본계획은 신체적 건강 문제와 심리적 외로움 문제 완화와 관련된 정책을 제시하였고, 이들은 공통적으로 논리적 한계를 지닌 성공적 노화와 활동적 노화 개념에 기반 해 있었으며, 분야의 협소함, 내용의 부실함, 정책의 불연속성을 띠고 있었다. 이상의 분석 결과는 연속성을 담보한 고령친화산업 활성화 정책이 내실 있고 다양해져야 하며, 성공적 노화의 탈-맥락성의 한계 및 소비자본주의와의 선택적 친화성, 활동적 노화의 예방 중심성, 노인의 (비)심리적 자원의 사회성, 사회투자국가 관련 리에이블먼트의 한계로부터 정책적 함의뿐만 아니라, 노화의 모델화를 통한 이분법적 노화 인식의 한계를 넘어 노화에 대한 사회 구성적 시각이 필요하다는 이론적 함의도 제공해주고 있다. 끝으로, 본 논문의 한계와 함께 필요한 후속 연구를 제안했다. The purpose of this research is to provide implications for the development of age-friendly industry of Korea by analyzing the age-friendly industry activation policy suggested by the Presidential Committee on Ageing Society and Population Policy in response to the population ageing problems. Policy and theoretical implications are derived from an analysis of age-friendly industry activation policy as directly related to the improvement of the three major problems (i.e. health, economy, and loneliness) of Korean older people. This analysis focuses on its specific content, common and core logic, and the validity of the logic. The results show that: 1)the first Plan for Ageing Society and Population suggests a policy for improving poverty, 2)the second Plan for Ageing Society and Population suggests a policy for improving health, and 3)the third Plan for Ageing Society and Population suggests a policy for improving health and loneliness. All policies not only are commonly based on the logically limited concepts of successful ageing and active ageing, but also are characterized by narrow realm, insufficient content, and fragmented policy. The results result in the following policy implications: 1)the age-friendly industry activation policy should be developed with continuity, sufficiency, and diversity, 2)lessons from the limitation related with the de-contextualisation of successful ageing and its elective affinity with consumer capitalism, 3)lessons from the prevention-oriented perspective of active ageing, and 4)lessons from the social characteristics of (non-)psychological resources, limitation of the reablement related with social investment state. The analyses also provide a theoretical implication that a different perspective on the social construct of ageing is needed beyond the dichotomy of ageing based on modelling ageing. Lastly, the paper suggests not only the limitation of the research but also the preferred follow-up studies regarding age-friendly industry activation policy.
