The altitudinal potential source contribution function (PSCFa) method was developed by considering topography and height of back trajectories. The PSCFa calculated on the contributions of trans-boundary transport to the hourly mean concentrations of aerosol optical depth (AOD) of the Aerosol Robotic Network (AERONET) in the Distributed Regional Aerosol Gridded Observation Networks (DRAGON) KORea-US Air Quality (KORUS-AQ) campaign from March 31 to July 1 in 2016. Eastern China ($33^{\circ}N{\sim}35^{\circ}N$ and $119^{\circ}E{\sim}121^{\circ}E$) can be the major source of trans-boundary pollution to the western area in South Korea resulted from PSCFa (0~700 m). In this study, AOD by Moderate Resolution Imaging Spectroradiometer (MODIS) was compared to verify the source regions. Regionally, the effects of the long-range transport of pollutants from the eastern China on air quality in south Korea have become more significant over this period.

Water vapor in the atmosphere is an influential factor of the hydrosphere cycle, which exchanges heat through phase change and is essential to precipitation. Because of its significance in altering weather, the estimation of water vapor amount and distribution is crucial to determine the precision of the weather forecasting and the understanding of regional/local climate. It is shown that it is reliable to measure precipitable water (PW) using long baseline (500-2000km) GPS observations. However, it becomes infeasible to derive absolute PW from GPS observations in Taiwan due to geometric limitation of relatively short-baseline network. In this study, a method of deriving Near-Real-Time PW from short baseline GPS observations is proposed. This method uses a reference station to derive a regression model for wet delay, and to interpolate the difference of wet delay among stations. Then, the precipitable water is obtained by using a conversion factor derived from radiosondes. The method has been tested by using the reference station located on Mt. Ho-Hwan with eleven stations around Taiwan. The result indicates that short baseline GPS observations can be used to precisely estimate the precipitable water in near-real-time.

The vitalization of Agro-industrial complex could be an alternative to enhance farmers off-farm income and overcome FTA's impacts on the import of agricultural products. However, it is evaluated the governmental policy on the Agro-industrial complex has not been successfully done as expected. The Agro-industrial complex started to be composed in 1984 and the 427 Agro-industrial complex have been composed nationwide by 2011. Meanwhile, three Agro-industrial complex where 61 factories are running have been composed and two Agro-industrial complex are being under construction in Seocheongun as of 2011. It is investigated that there are constraints in the government supporting systems for Agro-industrial complex. They are; Aged and poor infrastructure facilities, Weak marketing competition, Scattered supporting agencies, and Poor loan system, etc. In this respect, the policy of supporting system was suggested and recommended to vitalize Agro-industrial complex in the study. They are; Better loan system, Improving aged facilities, Marketing support, Assisting technology, Suppling labor power, and Forming factory-network, etc.

Interconnection of DG(Distributed Generation) into distribution systems and power quality are frequent subjects of discussion by distribution companies, regional electricity utilities and industrial customers. This situation makes many experts estimate a next generation of distribution systems which is composed of some micro-grids. But the proposed micor-grid is only mentioned as a small network with DG's, power quality compensators, communication and control equipments. In this paper, a decentralized coordination control algorithm of micro-grid which is able to supply the electric power with high reliability and quality, are proposed.

This paper is to research the difference of care workers' role in Sanatorium between urban and rural areas. Interviews have been conducted with 100 care managers with structured questionnaires in community care settings. The findings of the study are as follows. In the analysis of working with carers a care manager acting as a counsellor in rural was required rather more than any other role in working with clients' carers. In working with formal and informal networks, an administrative specialist role was also important in both areas. With resource management, there were some regional variances between rural and urban. In the urban area, a care managers as a coordinator was more required than as a broker. In the rural area, a care manager as a broker, selecting service resources for elderly clients was the most suitable role. In conclusion, in general rural care managers' roles were similar to those of many core managers in urban area. Among the many possible roles of care managers that effective continuity of care is to be provided for elderly clients in community care, two have been specified as essential roles. The first is the role of care managers that provides coordination and integration of services at the clients' levels as a care manager as an implementer, a linkman, counsellor. The second is at the system level which is possible role for coordination and linkage of programs as a characteristics of care managers, task with formal & informal network, community resources, available residential & NHS resourcesw.

In public transportation, smart cards have been introduced for the purpose of convenient payment systems. The smart card transaction data can be utilized not only for the exact and convenient payment but also for civil planning based on travel tracking of citizens. This paper focuses on the analysis of the transportation convenience using the smart card big data. To this end, a new index is developed to measure the transit convenience of each region by considering how passengers actually experience the transportation network in their travels. The movement data such as movement distance, time and amount between regions are utilized to access the public transportation convenience of each region. A smart card data of five working days in March is used to evaluate the transit convenience of each region in Seoul city. The contribution of this study is that a new transit convenience measure was developed based on the reality data. It is expected that this measure can be used as a means of quantitative analysis in civil planning such as a traffic policy or local policy.

Regional development and community design has become very important these days. Especially in Hyogo Prefecture after the Great Hanshin Awaji Earthquake, voluntary works have become more popular. With citizen participation, environmental circumstances change a lot. It is becoming very difficult for municipal governments alone to achieve every desirable project. NPOs made of professional members in the Hanshin area have conducted notable activities after the earthquake. At the same time it is necessary also to educate citizens for community design with greenery. These people will support their town design along with professionals. Awaji Landscape and Horticulture Planning Academy provides an excellent educational program, an introduction and examination of which should be valuable. The main concept of the education program is to foster the growth of local community design leaders. Students appreciated the programs very much even if initially they expected a more practical program about planting than programs that teach community design. Many people are active in their own towns to create better environments and communities. The network system "Alpha Green-Net" is functional to support graduates of the course. In the future these educational programs for citizens will becomes very important. Other cities are starting to have their own progrms, but they are still very short term. "Alpha Green-Net" is in the process of growing. Many members are very keen to develop their own abilities. In the future these NPOs should become independent. To help these NPOs become independent and active the educational programs should consider and teach about how to do this more in the future.
