홍수빈도분석의 실용적 측면의 목적은 특정 재현기간에 대하여 발생 가능한 홍수량을 설계홍수량(design flood)으로 설정함으로써 댐, 제방, 배수시설, 하수관거 등의 치수기능을 가진 치수시설물이 설계홍수량 내에서 홍수로 인한 피해를 발생시키지 않도록 그 규모와 기능을 설계함에 있다. 특히 우리나라의 경우 유량자료의 부족으로 강우빈도분석을 수행하여 재현기간별 확률강우량을 먼저 산정하고 이를 강우-유출모형을 통해 확률홍수량으로 전환한 뒤 하천등급에 따른 재현기간 기준에 따라 설계홍수량을 산정하고 있다. 그러나 이와 같이 결정된 설계홍수량이 특정유역에서 발생될 수 있는 피해규모에 대해 얼마나 적정한 지의 여부를 과학적으로 판단하기 위한 연구는 국내·외에서 찾아보기 어려우며, 이러한 문제를 개선하기 위한 기초 이론을 제공하는 것이 본 연구의 가장 중요한 목표이다. 홍수빈도분석을 통해 산정된 설계홍수량의 적정성 여부를 과학적으로 판단하기 위해 최근에 진행된 해외의 몇몇 연구에서는 총 기대비용함수(total expected cost function)의 개발에 근거한 최적설계홍수량을 활용할 수 있음을 제안한 바 있다. 이 개념은 계획된 설계홍수량 이상에서 발생될 수 있는 피해함수(damage function) 및 기대피해함수(expected damage function)와 비용함수(cost function)가 결정되면, 이로부터 총 비용을 나타내는 총 기대비용함수(total expected cost function)을 도출하고 총 기대비용함수가 최소가 되는 최적설계홍수량(optimal design flood)을 산정하여 이를 계획된 설계홍수량(tentative design flood) 비교함으로써 계획된 설계홍수량의 적정성을 판단하는 과정을 기초이론으로 활용한다. 본 연구에서는 불확실성으로 발생되는 범위를 고려한 최적설계홍수량을 산정하기 위하여 Metropolis-Hastings 알고리즘을 사용하였으며, 자료의 종류에 따른 홍수량의 변화를 분석하기 위하여 년최대계열 및 부분시계열 자료를 각각 적용하였다. 한강유역에서 가평대성, 여주 및 한강대교 수위표 지점에서 측정된 자동관측유량장치에 의한 홍수량 자료를 활용하였으며, 최적설계홍수량이 기존 설계홍수량에 비해 크게 산정됨을 알 수 있었다.

세계가 일일 생활권화 됨과 더불어 국제교류가 활발해지므로써 횡문화 간호 연구는 전문직 간호(Professional Nursing)에 있어서 매우 중요한 부분을 차지하고 있음을 많은 문헌을 통해서 알 수 있다(Brink, 1976 : Leininger, 1977 : Roberston & Boyle, 1987). 횡문화 간호연구는 서로 다른 문화적 배경을 가진 사람들을 잘 이해하고 그들의 건강을 돌봄에 있어서 더욱 효과적이고, 안전한 간호를 할 수 있을 뿐만 아니라 간호이론 개발, 간호모형(Model) 개발에 있어서도 매우 중요한 역할을 한다고 믿는다. 본 연구는 1984년에서 1987년 사이에 전문적 간호연구지에 실린 10편의 횡문화 간호연구와 관련된 논문들을 발췌하여 간호지식체의 본질적인 과정인 비판적 문헌고찰을 통해 각 논문들을 비교 분석 한 것으로써, 미래의 간호연구를 위한 간호실무, 간호교육, 간호연구 방법 및 간호 행정면에서 그 적용성을 높여줄 것이다. 비판적 문헌고찰을 위한 기준은 Burns와 Grove(1987)의 방법을 참고하여 아래와 같이 선정하였다. 1. 분석대상 : 목적, 가설 진술, 문헌고찰, 표본조사, 방법론적 논점, 결과 해석 2. 이론적 틀의 유도 흑은 통합 3. 발전적인 간호수행을 위한 중요성, 적용성 및 제언 이상의 내용으로 비교 분석을 해본 결과 1984년에서 1987년 사이에 발표된 횡문화 간호에 관한 논문들의 주제는 주로 여성을 대상으로 한 건강돌봄, 자가간호, 건강신념, 수유, 임신 그리고 간호사와 소수민족 노인과의 의사소통 양상 등으로 나누어 볼 수 있었다. 이론적 틀은 주로 사회학, 정신심리학, 인류학 이론으로부터 도출되었고, 오직 두 편만이 간호 이른에 틀을 둔 것으로 나타났다. 1. 10개의 논문의 가설과 목적의 분석에 있어서 4편의 논문은 목적과 가설이 구체적으로 진술되어 있었고, 나머지 6편은 목적이 전반적으로 진술되어 있었으며 가설도 구체적이지 않았다. 이러한 제한점은 각 논문의 연구자가 문헌고찰을 충분히 하지 못하고 단지 수편의 논문만을 제시 한 데서 비롯되었다고 분석 해 볼 수 있겠다. 2. 문헌고찰 부분에서는 각각의 연구주제를 지지해줄 수 있는 문헌들이 충분히 고찰되지 못하였고, 이론적배경 또한 횡문화 이론과의 관련성이 적었다. 또한 횡 문화 연구에 기초가 되는 연구대상자의 사회 인구학적 특성과 역사적 배경은 잘 나타났으나, 이론적 연구와 경험적 연구 간에 괴리가 있었다. 3. 표본추출방법은 문화에 기반을 둔 대상자를 선정한다는 점에서 한계성 이 있었다. 4. 방법론적 이유로는 대상자와의 면담시간이 구체적으로 기술되지 않았으며, 고유한 언어를 통역하는 과정에서 의미론적 문제에 대한 고려가 부족하였다. 면접과 기록과정에서 보면 자료의 기록과정과 분류 및 분석과정이 명시되어 있지 않았다. 참여관찰과 면접방법을 사용시 이에 대한 자세한 기술이 되어 있지 않았다. 5. 연구결과의 적용 및 이에 대한 논의는 상당히 제한되어 있었는데, 수편의 연구만이 방법론 문제점과 앞으로의 연구분야에 대한 전망을 제시하였으며, 특이한 것은 어 떤 연구자도 이른 개발을 위한 적용 및 임상실무적 차원에서 간호에 대한 제언을 하지 않았다.

The purpose of this study was to investigate the effects of engineering design-based ocean cleanup classes on STEAM attitudes and creative engineering problem-solving dispositions. Furthermore, during this process, we tried to determine interesting points that students encountered in engineering design-based classes. For this study, a science class with six lessons based on engineering design was developed and reviewed by a professor who majored in engineering design, along with five engineering design experts with a master's degree or higher. The subject of the class was selected as the design and implementation of scientific and engineering measures to reduce marine pollution based on the method implemented in an actual Ocean Clean-up Project. The engineering design process utilized the engineering design model presented by NGSS (2013), and was configured to experience redesign through the optimization process. To verify effectiveness, the STEAM attitude questionnaire developed by Park et al. (2019) and the creative engineering problemsolving propensity test tool developed by Kang and Nam (2016) were used. A pre and post t-test was used for statistical analysis for the effectiveness test. In addition, the contents of interesting points experienced by the learners were transcribed after receiving descriptive responses, and were analyzed and visualized through degree centrality analysis. Results confirmed that engineering design in science classes had a positive effect on both STEAM attitude and creative engineering problem-solving disposition (p< .05). In addition, as a result of unstructured data analysis, science and engineering knowledge, engineering experience, and cooperation and collaboration appeared as factors in which learners were interested in learning, confirming that engineering experience was the main factor.

This paper presents an intuitive 3D modeling interlace based on a field study and prototype development. The process and tools of modeling were observed in workshops of professional design model making, day modeling, wood caning and glass crafting. The Spray Modeling interlace was developed from the observational analysis of the field study. It is a 3D modeling interface which combines particle spraying and day modeling in Virtual or Augmented Reality space. Virtual volume particles are sprayed on frames in Augmented Reality space as day modeling. It adopts a real air spay gun as a tangible interface device which provides coherent sound and air-force feedback. The prototype development and a user study showed that the interface supports new patterns of form development and expression. Control interfaces and requirements of auxiliary devices were found to be improved. This study examines the potential of the new interlace for designers working in 3D virtual and augmented reality. The new spraying interface is also expected to be used as an alternative interface in 3D computer workspace, games, education software and media art.
