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.

Purpose: Treatment and prognosis in patients with pelvic bone fracture depend on the characteristics of the fracture and the stability of the pelvic ring. The purpose of this study is to analyze the characteristics of and the relationships between fracture patterns, injury mechanisms, clinical courses, and prognoses according to the hemodynamic pattern. Methods: Between January 2004 and September 2006, 89 patients under diagnosis of pelvic bone fracture were retrospectively analyzed on the basis of medical records and radiologic examinations. Patients with confirmed hemorragic shock with a systolic pressure of less than 90 mmHg were defined as the shock group. Young`s classification was used to characterize fracture patterns. Factors relating to the clinical manifestation and to treatments such as transfusion and surgery were analytically compared. Results: The mean age of the patients was 48.8±18.7, among which 49 (55.1%) were male. The numbers of shock and non-shock patients were 35 (39.3%) and 54 (60.7%) respectively. Eighteen (51.4%) of the shock patient had injuries resulting from pedestrian accidents (p=0.008). According to Young`s classification, lateral impact fractures amounted to 20 and 33, front-rear impact fractures to 9 and 20, and multiple fractures to 6 and 1 among the shock and non-shock patients, respectively (p=0.027). Thirty-nine (39) cases in non-shock injuries were conservatively managed while 18 cases in shock injuries were surgically treated. In the shock group, the liver and the kidney were often damaged, as well. Among the shock patients, the average admission period was 7.5±8.7 days in intensive care and 55.1±47.9 days in total, which were longer than the corresponding numbers of days for the non-shock patients (p<0.05). No deaths occurred in the non-shock group while 5 deaths (14.2%) occurred in the shock group (p=0.007). Conclusion: The factors affecting hemodynamic instability in patients with pelvic bone fracture are injury mechanism, classification of fracture, and associated injuries.

영국 노인의 현금직접지급 정책 수혜 경험에 관한 사례 연구

박승민 ( Seung Min Park ) 한국가족복지학회 2011 한국가족복지학 Vol.16 No.2

본 논문의 목적은 영국 노인들이 장애인 운동과 시민권에 기반하여 형성된 노인 현금직접지급 정책 수혜의 실제 경험을 질적으로 분석하는 것이다. 연구 대상자는 영국 런던에 거주하면서 노인 현금직접지급 정책 수혜 대상자인 65세 이상 장애 노인 23명이고, 자료 수집은 반-구조화된 심층 인터뷰(Semi-structured Depth Interview)를 통해 이뤄졌다. 자료의 분석은 지오르기(Giorgi)의 현상학적 분석 방법에 따라 이뤄졌다. 분석 결과 긍정적 경험과 부정적 경험이라는 두 가지 구성 요소가 발견되었으며, 전자는 다섯 가지 하위 구성 요소로, 후자는 네 가지 하위 구성 요소로 재분류 되었다. 즉, 긍정적 경험은 노인이 서비스의 수혜 시간, 장소, 제공자와 내용을 결정할 수 있는 점과 가족 간 갈등 해소에 도움이 된다는 것이었다. 반면, 부정적 경험은 지급 받은 현금 관리의 어려움, 서비스 제공 부 자격자 관리 실패로 인한 피해, 서비스에 대한 구체적인 정보 접근의 어려움, 복잡하고 느린 행정 절차였다. 이와 같은 분석 결과를 바탕으로 한국의 노인복지 정책 발전의 잠정적 가능성에 대해 논의하였다. The purpose of this research is to qualitatively analyze the experiences of British older people who have exercised the direct payment option. Semi-structured depth interviews as well as Giorgi`s phenomenological analysis tool were applied to analyze the responses of 23 older people living in London. The analysis reveals five positive experiences as well as four negative experiences. The former includes possibility for older people to determine the time, place, provider and contents of the service with the effect of decreasing family conflict. The latter encompasses difficulties in managing cash, damages caused by unqualified service provider, limited information access for service, and complicated and slow administration. The findings derived from this research provide policy implications for improving Korean welfare policies for older people.
