Green infrastructure planning represents landscape planning measures to reduce particulate matter. This study aimed to derive factors that may be used in planning green infrastructure for particulate matter reduction using text mining techniques. A range of analyses were carried out by focusing on keywords such as 'particulate matter reduction plan' and 'green infrastructure planning elements'. The analyses included Term Frequency-Inverse Document Frequency (TF-IDF) analysis, centrality analysis, related word analysis, and topic modeling analysis. These analyses were carried out via text mining by collecting information on previous related research, policy reports, and laws. Initially, TF-IDF analysis results were used to classify major keywords relating to particulate matter and green infrastructure into three groups: (1) environmental issues (e.g., particulate matter, environment, carbon, and atmosphere), target spaces (e.g., urban, park, and local green space), and application methods (e.g., analysis, planning, evaluation, development, ecological aspect, policy management, technology, and resilience). Second, the centrality analysis results were found to be similar to those of TF-IDF; it was confirmed that the central connectors to the major keywords were 'Green New Deal' and 'Vacant land'. The results from the analysis of related words verified that planning green infrastructure for particulate matter reduction required planning forests and ventilation corridors. Additionally, moisture must be considered for microclimate control. It was also confirmed that utilizing vacant space, establishing mixed forests, introducing particulate matter reduction technology, and understanding the system may be important for the effective planning of green infrastructure. Topic analysis was used to classify the planning elements of green infrastructure based on ecological, technological, and social functions. The planning elements of ecological function were classified into morphological (e.g., urban forest, green space, wall greening) and functional aspects (e.g., climate control, carbon storage and absorption, provision of habitats, and biodiversity for wildlife). The planning elements of technical function were classified into various themes, including the disaster prevention functions of green infrastructure, buffer effects, stormwater management, water purification, and energy reduction. The planning elements of the social function were classified into themes such as community function, improving the health of users, and scenery improvement. These results suggest that green infrastructure planning for particulate matter reduction requires approaches related to key concepts, such as resilience and sustainability. In particular, there is a need to apply green infrastructure planning elements in order to reduce exposure to particulate matter.

우리나라는 현재 개발되어 적용되고 있는 홍수피해잠재능(Potential Flood Damage, PFD) 산정방법은 잠재성요소(인구, 자산, 사회기반시설, 도시화율)와 위험성요소(홍수피해액, 확률강우량, 외수방어능력, 댐 및 저수지, 내수방어능력)로 산정 후 지역평가를 통해 그룹(A,B,C,D)별로 평가하고 있다. 하지만, 홍수피해잠재능(PFD) 산정인자가 많아 자료조사 및 구축에 많은 시간이 소요 되며, 인자별 다양한 공간적 범위로 인해 실무 적용에 어려움이 있다. 또한, 소구역 단위 평가로 인해 하천의 침투 특성을 반영하지 못하여 하천 주변의 중요도 평가가 미흡한 실정이다. 이를 위해 본 연구에서는 중요도 분석 인자 단순화를 통해 자료 조사 및 구축 시간 단축과 더블어 위험성요소를 내포하는 홍수위험지도 사용을 통해 작업을 간소화하고, 하천 주변까지 고려하여 중요도 평가하는데 목적이 있다. 본 연구에서는 낙동강권역을 대상으로 홍수위험지도 및 중요도 분석 인자(인구, 자산(공시지가), 시회기반시설(도로,철도), 도시화율(시가화지역)) 공간정보를 구축하였고, 점수할당법에 의한 인자별 중요도 분석 및 상관성 분석을 통해 피해우선순위를 분석하였다. 분석결과, 인구·자산(공시지가) 인자가 높은 구역이 대체로 사회기반시설 연장 및 도시화 면적이 높게 나타났으며, 하천의 치수단위 구역별 중요도 분석시 인구·자산(공시지가) 두가지의 인자로도 치수안전도 결정에 활용이 가능할 것으로 판단된다.

Each area of society has changed because of the development of information technology. Especially, the advent of NCW based on the technology of network has become a new paradigm for executing warfare. Effectiveness of NCW can be maximized by building the C4I system which is a core system of NCW. However, if we don't consider the influence in term of human dimension, we can't expect the effect of C4I system, since the key factor in C4I is human. In this paper, we propose an algorithm for evaluating Combat Power Effectiveness by considering the Influence of Human Factors that wasn't reflected in the past. Based on experimental validation our algorithm is more substantial than baseline algorithms. In addition, we proved that the Influence of Human Factors(e.g. collaboration) is the most important in battlefield. Therefore, proposed algorithm can be used for enhancing not only mission effectiveness in terms of military field but also work performance by effective Human Resource Management in terms of an enterprise.

The formation of early korean scientific community is a dynamic process of korean modern history in which colonialization, liberation, United States Army Military Government and Korean War is included. Particularly, scientist's crossing over the border into north korea and south korea have profound effect on the early stage of our scientific community. This period is so important to understand the nature of korean scientific community that we need to re-interpret the role of 'ideology' in the development of scientific community. On the other hand, war is a important element in our formation of the image of the science. This study purported to interpret the problem of political ideology, it's role in the formation of early scientific society, it's implication on our idea of science positively. Also the study is a an attempt to re-construct the scientist's struggle(1945-1950) to demarcate new science from old, colonial science.

This study investigated the consumer acceptance process of the fourth industrial revolution new product to be introduced into the market in the future. The 4th Industrial Revolution new products are technological advances compared to the existing ones. The technology acceptance model that was used in the past has been modified to reflect variables like the social effects of the 4th Industrial Revolution, expected experience, and perceived risk. Modified models were proposed and verified. Six representative new products of the 4th Industrial Revolution were selected and examined by 40 respondents, and the hypotheses were verified using programs such as SPSS and AMOS. And conclusions and implications are as follows. First, the innovativeness of the fourth industrial revolution new products influences positive evaluation factors such as expected experience and perceived usefulness and it also affect positively to the perceived risk. In addition, the expected experience of the fourth industrial revolution new products has a great effect on the perceived usefulness and social influence, but it didn't affect to the perceived risk. Like the results of the TAM model, purchase intention of the fourth industrial revolution new products are strongly influenced by perceived usefulness. Finally, the perceived risk of the new product of the 4th Industrial Revolution had no statistically significant effect on the purchase intention, and the social influence of the 4th Industrial Revolution had a significant effect on the purchase intention. In general, respondents are highly aware of the social impact of the Fourth Industrial Revolution and seem to be very positive in this respect.
