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.

Purpose - The purpose of the paper is to look into and review the management and operation of Chinese infrastructure process, especially focusing on port industry. Research design, data and methodology - The research methods to be applied is to examine PPPs that is a key way of cooperation in many infrastructure investment, financial matters, and then port industry as well. Results - It is well noticed that Chinese government has well managed with project, planning and investments in national infrastructure matters. Especially, this is clear message that government institutions for infrastructure planning has been well organized with systematic structure. However, even if it is involved with some risky business, PPPs should be asked for cooperation in the areas of financial, institutional and logistic part of infrastructure development in China. Conclusions - Every country has been in promoting its infrastructure development and it is not an exception in China. In order to get over inefficiency done by public sectors, Chinese government has invited a private sector in the form of PPPs, which gives more competitive opportunities, especially in port industry.

The objective of the study is to suggest planning directions for practical use and to find the conditions of tourist attractions in rural villages founded on city-dweller's preference. Both a questionnaire and a field survey were used for the study. Selected were four villages such as Oryan-ri, gachun-ri, Junggi-ri, and Gyochon-ri. The results of the study are as follows: City-dweller's valued on natural environment resources in rural tourism and felt uncomfortable to accommodations. The scoring system reflecting functions of six resources showed that common problems encountered in rural tourism were lacks of people's organization, and human exchange mind, and tourism-related leasure places and facilities. Based upon the results, some measures to develop villages were suggested.

In the planning process, there are five directions to planning residential sites. Firstly, the site must be planned to allow continuity with the city space, or created to conform to the city structure. Secondly, plans for community space and programs as well as convenience facilities must coexist in the road space. Thirdly, in terms of view, the site must be planned in territories to secure identity of the site. Fourthly, in terms of the environment, the site should utilize the natural environment. Lastly, in terms of infrastructure, the site should include a pedestrian-centered road system as well as establishing city infrastructure facilities for a combined planning in the municipal dimension. So far we have looked at planning methods for an apartment site that can be integrated into the existing city. The study into five elements to planning a large-scale apartment site, context, community, landscape, environment and infrastructure, and their relationship among each other must continue on.

Recently, interest and financial investment in community infrastructure have been growing. Accordingly, Korean Ministry of Land, Infrastructure and Transport suggested a standard for community infrastructure planning. The standard was based on time distance which represents citizens' accessibility to infrastructure facilities. This paper presents a method to use the navigation application programming interface (API) to calculate travel time. Buffer analysis using Euclidean distance has been widely used so far to evaluate accessibility. However, this method has limitation in that it does not reflect situations in the real world such as crosswalks and slope ways. The infrastructure accessibility indices of local towns in Yeonsu-gu, Incheon were computed based on the time obtained by navigation API. Also, Yeonsu-gu was spatially analyzed to reveal the resident units that are marginalized from community infrastructure facilities. Using navigation API enables to compute realistic accessibility indices and to find unbenefitted residential areas. The method presented in this paper can help community infrastructure planners for their facility spatial plan and budget distribution.

Cities in Korea have rapidly urbanized and they are not well prepared for natural disasters which have been increased by climate change. In particular, they often struggle with urban flooding. Recently, green infrastructure has been emphasized as a critical strategy for flood mitigation in developed countries due to its capability to infiltrate water into the ground, provide the ability to absorb and store rainfall, and contribute to mitigating floods. However, in Korea, green infrastructure planning only focuses on esthetic functions or accessibility, and does not think how other functions such as flood mitigation, can be effectively realized. Based on this, we address this critical gap by suggesting the new green infrastructure planning framework for improving urban water cycle and maximizing flood mitigation capacity. This framework includes flood vulnerability assessment for identifying flood risk area and deciding suitable locations for green infrastructure. We propose the use of the combination of frequency ratio model and GIS for flood vulnerability assessment. The framework also includes the selection process of green infrastructure practices under local conditions such as geography, flood experience and finance. Finally, we applied this planning framework to the case study area, namely YeonJe-gu an Nam-gu in Busan. We expect this framework will be incorporated into green infrastructure spatial planning to provide effective decision making process regarding location and design of green infrastructure.

In order to survive in a competitive environment, many companies are taking much interest in building IT infrastructure and are investing in that area. But, despite of all the interest and investments, many companies are unsatisfied and confused because of the lack of guidance and understandings of IT infrastructure. Therefore the purpose of this study is to prove that the level of IT usage is different according to organizational characteristics and industrial categories, and to give a guideline to companies' planning on newly building IT infrastructure. In conclusion, companies newly planning on building IT infrastructure should consider the amount of information technology functional uses according to the organizational characteristics and industrial category and they follow the below guidelines. On building the IT infrastructure the organization having the characteristics of formalization should consider and provide the standardization function first. The companies having the characteristics of decentralization should consider and provider firstly the application and communication function. And the companies having the characteristics of specialization should consider and provider the security function.
