This paper presents a case of community participatory neighborhood park design. The site, Yangji park, is located in Sandang-dong, Dongjak-gu, Seoul and the area is about 1,870m. Neighborhood park is defined as an outdoor space which is close to people´s home and is considered to be their own, because of the residents´ collective responsibility, family association, and frequent shared use. It is a place for pleasant rest area for community, sharing a sense of nature and retaining a sense of tradition and culture which is disappearing in a city. It is related to the daily life of the people near the site and becomes a place to let the community increase dialogue and understanding between people. On the other hand, participatory design is a design in which people participate in the design process. Thus people can understand the project well, present their opinions better, and reconcile conflicts between the different interests of people. This design applied a community participatory design method to design a neighborhood park. The major strategies for participatory design were ´workshop´, ´card game´, ´walking site´, ´interview´, and ´questionnaire´. Eight workshops were performed for the participation design. The major spaces and facilities elected by participants were the ´main entrance plaza´, ´entrance symbol space´, ´children´s ´playground´, ´multipurpose sport ground´, ´grass land´, ´foot-pressure area´, ´spaces symbolizing a rock mountain and an old well´, ´space for youth´, ´a pavilion´, etc. From this selection, design concept alternatives were generated by participants. The aster plan was developed from these design alternatives with the help of landscape architects. It was revised by ist visits and community discussions. People were also involved in the construction process and left their own works, such as hand prints, on the site. After construction, residents continued to maintain the park by themselves. As a result, It was found that participatory design was very effective for people´s satisfaction and sustainable park management. By involving people more in the process they developed a sense of community, a sense of ownership, and attachment to the place. In conclusion, it is suggested that we need to develop an effective people´s participation method to Korean society.

As urban function has become diversified and complicated, multifunctional complex facilities to satisfy new functional desires are necessary. Since local autonomy started, many facilities previously run and managed by central administrative agencies are now under management of localities, and functionally, the necessity for governments complexes town to satisfy diverse taste of populace such as creating local community becomes imminent. Analyzing characteristics by space composition factor of the public health center, newly built as part of such governments complexes town and understanding required area of each part, this project is to be used as basic material for construction plan of public health center that is equipped with local characters while devising construction of the public health center in the governments complexes town. Research method is to analyze four public health center facilities located in governments complexes town sites built after 2007, among twenty five public health centers in Seoul, by spatial functions. Also, based on statistical documents of usage of public health center facilities, research over spatial compositional factors and area composition has been conducted. As a result, connectivity between local government building located inside the governments complexes town and public health center and that of spatial composition factor by part, area ratio by part and floor type of public health center are comprehended. Connectivity type of public health centers are divided into horizontal and vertical connectivity and it is found that spatial composition of public health center is compartmentalized into low level, mid level and high level, to make access by users easier. Level type is decided as radial, rotational and combined by hallway connecting facilities.

EIA(Environmental Impact Assessment) was introduced in 1979 by our gorvernment to cope with serious environmental problems. Recently environmental pollution has been controlled severely than ever because pollution phenomena became more comlpicated and arrcordingly the damage more terrible. For the EIA system to achieve its goal effectively, systematic and scientific approach should be found out. For this reason the techniqes such as GIS(Geographic Information System) and RS(Remote Sensing) come to front strongly. The purpose of this paper is to investigate the application techniqes of GIS and RS to the EIA system. Haw-Won Myen, Hae-Nam Gun, Chun-Nam and its related area, which will be developed to be a sightseeing area, were selected as the study area. Applications of GIS resulted some important outcome such as earthwork calculations, landuse models, aspect maps, stability of slanting surfaces, elevation models, estimation of real estates, etc. GIS applied EIA proved to be very useful for the project managers and planners to plan, evaluate, judge the enviormental problems.

In Korea, previously implemented road construction project caused a big budget waste due to overestimation of transport demand. There could be reasons for such inaccuracy of transport demand estimation, but the main reasons are: (1) low reliability of used basic road transport data and (2) inadequate sharing of data among agencies/departments. The National Transport Database and the Household Travel Database in Seoul Metropolitan Area, two representing basic road transport database, will be used to the establishment of a road construction plan that will be promoted afterwards. However, these materials have problems such as low reliability and inadequateness, too. Hence, focusing on transport demand estimation related databases, this paper will make proposals for enhancing their reliability and data sharing.

Recently, stereotactic radiosurgery plan is required with the information of 3-D image and dose distribution. A project has been doing if developing LINAC based stereotactic radiosurgery since April 1991. The purpose of this research is to develop 3-D radiosurgery planning system using personal computer. The procedure of this research is based on two steps. The first step is to develop 3-D localization system, which input the image information of the patient, coordinate transformation, the position and shape of target, and patient contour into computer system using CT image and stereotactic frame. The second step is to develop 3-D dose planning system, which compute dose distribution on image plane, display on high resolution monitor both isodose distribution and patient image simultaneously and develop menu-driven planning system. This prototype of radiosurgery planning system was applied recently for several clinical cases. It was shown that our planning system is fast, accurate and efficient while making it possible to handle various kinds of image modalities such as angiography, CT and MRI. It makes it possible to develop general 3-D planning system using beam's eye view or CT simulation in radiation therapy in future.

The Brazos River is one of the longest rivers contained entirely in the state of Texas, flowing over 700 miles from northwest Texas to the Gulf of Mexico. Today, the Brazos River Authority and Texas Commission on Environmental Quality interest in drought protection plan, waterpower project, and allowing the appropriation of water system-wide and water right within the Brazos River Basin to meet water needs of customers like farmers and local civilians in the future. Especially, this purpose of this paper primarily intended to provide the data for the engineering guidelines and make easily geological mapping tool. In the Brazos River basin, many stream-flow gage station sites are not working, and they can not provide stream-flow data sets enough for development of the Probable Maximum Flood (PMF) for use in the evaluation of proposed and existing dams and other impounding structures. Integrated GIS-Spatial Interpolation (GIS-SI) tool are composed of two parts; (1) extended GIS technique (new making interface for hydrological regionalization parameters plus classical GIS mapping skills), (2) Spatial Interpolation technique using weighting factors from kriging method. They are obtained from the relationship among location and elevation of geological watershed and existing stream-flow datasets. GIS-SI technique is easily used to compute parameters which get drainage areas, mean daily/monthly/annual precipitation, and weighted values. Also, they are independent variables of multiple linear regressions for simulation at un gaged stream-flow sites. In this study, GIS-SI technique is applied to the Brazos river basin in Texas. By assuming the ungaged flow at the sites of Palo Pinto, Bryan and Needville, the simulated daily/monthly/annual time series are compared with observed time series. The simulated daily/monthly/annual time series are highly correlated with and well fitted to the observed times series.

In order to investigate the runoff characteristics of nonpoint source pollutants in the Lake Doam watershed, water quality and flow rate were monitored for 38-rainfall events from 2009 to 2016. The EMC values of SS, COD, TN and TP were in the range of 33~2,169, 3.5~56.9, 0.09~7.65 and $0.06{\sim}2.21mg\;L^{-1}$, respectively. As a result of analyzing the effect of rainfall factor on the nonpoint source pollutant load, EMCs of SS, COD and TP showed a statistically significant correlation with rainfall (RA) (p<0.01) and SS showed highly significant correlation with maximum rainfall intensity (MRI, R=0.48). The load ranges of SS, COD, TN and TP were 10.4~11,984.6, 1.1~724.4, 0.6~51.6 and $0.03{\sim}22.85ton\;event^{-1}$, respectively, showing large variation depending on the characteristics of rainfall events. The effect of rainfall on the load was analyzed. SS, COD and TP showed a positive correlation, but TN did not show any significant correlation. The annual load of SS was the highest with $88,645tons\;year^{-1}$ in 2011 when rainfall was the highest with 1,669 mm. The result of impact analysis of nonpoint source pollution reduction project and land-use change on runoff load showed that pollutant load significantly reduced from 2009 to 2014 but SS and TP loads were increased from 2014 to 2016 due to increase in construction area. Therefore, we suggested that nonpoint source pollution abatement plan should be continued to reduce the soil loss and pollutants during rainfall, and countermeasures to reduce nonpoint source pollution due to construction need to be established.

In order to reduce the health inequalities within a society changes need to be made in broad health determinants and their distribution in the population. It has been expected that the Health impact assessment(HIA) and Healthy Cities can provide opportunities and useful means for changing social policy and environment related with the broad health determinants in developed countries. HIA is any combination of procedures or methods by which a proposed 4P(policy, plan, program, project) may be judged as to the effects it may have on the health of a population. Healthy city is one that is continually creating and improving those physical and social environments and expanding those community resources which enable people to mutually support each other in performing all the functions of life and in developing to their maximum potential. In Korea, social and academic interest regarding the HIA and Healthy Cities has been growing recently but the need of HIA and Healthy Cities in the perspective of reducing health inequality was not introduced adequately. So we reviewed the basic concepts and methods of the HIA and Healthy Cities, and its possible contribution to reducing health inequalities. We concluded that though the concepts and methods of the HIA and Healthy Cities are relatively new and still in need of improvement, they will be useful in approaching the issue of health inequality in Korea.
