In recent years, tram has been the focus of a new mode of public transportation that can solve traffic jams and decrease public transit usage and environmental problem. This research is in the works to develop a tram signal controller and signal control strategies, and aim to resolve the problem of what could happen if a tram system was installed in general road. We developed the hierarchical signal control strategies to obtain a minimum tram bandwidth and to minimize vehicle delay, in order to perform a priority control to include passive and active signal priority control strategies. The strategies was produced for S/W and H/W, it is based in standard traffic signal controller. We conducted a micro simulation test to evaluate the hierarchical signal control strategies, which showed that the developed optimization model is effective to prevent a tram's stop in intersection, to reduce a tram's travel time and vehicle's delay.

In Korea, playgrounds have been developed quantitatively and qualitatively. However, there is a lack of interest in the play needs of children with disabilities. With this in mind, this study is concerned about the planning and design process of the inclusive playground constructed in 2016 at Seoul Children's Grand Park. The case study covered the Kkumtle Kkumtle playground in Seoul Children's Grand Park and was completed in December 2015. This playground is the first case of an inclusive playground ever built in Korea. The concept of the inclusive playground established in this study is: (1) a playground where not only children with disabilities but both children with disabilities and children without disabilities can play together; (2) a playground for both children with disabilities accompanied by their families and children without disabilities accompanied by family members with disabilities; (3) a playground that ensures universal accessibility to the entire space including play facilities; and (4) a playground where the most essential functions of a playground-fun, curiosity, and adventure-are centered on various activities. In conclusion, we presented limitations and opinions for improvements to design and policy proposals for social expansion of inclusive playgrounds. There are three ways to overcome limitations in design. First, there is a need for an in-depth study of play characteristics by type of disabilities of children. Second, it is necessary to develop facilities suitable for the actual situation of Korea through various social experiments. Third, if the inclusive playground centered on facilities is presented in this study, then several types of integrated playgrounds should be implemented in the future.

Purpose: This study is the analysis of the relationship between the physical safety of the urban spaces and the aging in place tendency of the elderly. Method: For analysis, the physical safety of the urban space is divided into four elements: outdoor space and building safety, pedestrian safety, transportation safety and living safety, and for aging in place, the 5-point Likert scale was used. A questionnaire survey was conducted for 411 elderly people aged 65 or older living in Seoul for each of the five urban community in Seoul. Results: 78.6% of the respondents answered that they are good at continuing to live in the present living area, the elderly living in Seoul has the high tendency of aging in place. The ratio of respondents who answered that good at living continuedly is in the order of southeast, northwest, southwest, northeast, and downtown. Conclusion: When the percentage of respondents who answered that they are good at staying in the current living area is high, not only the overall physical safety but also the average of the physical safety factors of the urban space are also high, physical safety of urban spaces is a factor affecting aging in place. Based on the results of the study, it can be applied as a method to create a safe city in the process of city development or urban renewal in the future.

This study aims to survey whether local governments have legislated laws and regulations on environment impact assessment system, to compare and analyze specific projects and their scale, assessment items, and procedures & discussion process, to identify issues and generate improvement plans, and to suggest a direction for future legislation to local governments that plan to legislate laws and regulations in the future. Major outcome of the study are as follows. First, terminologies used for environment impact assessment by local governments need to be unified. Also, laws and regulations need to be legislated soon. Second, in "urban development project" areas, a total of nine project areas including "quarrying of soil and stone, sand, gravel, and minerals" was essential common projects. A total of six project types were added or newly established compared to national systems. Among them, four project types were added within national-level project areas and two project types were not available under the national-level project areas and newly added due to the nature of local governments. Third, in terms of project scale, scale enhancement of "urban development project" was most common. Analysis showed that in case of clean natural environment such as Cheju Island, it is necessary to consider reinforcing project areas where development activities take place directly in forests or rivers such as "industrial base and complex development", "water resource development", and "development of tourism complex." Fourth, the discussion and review procedures of assessment reports were similar to those at government level. However, in case of Seoul city, it is required to write a "preparation plan" before drafting an assessment report. The city features partial introduction of scoping and screening, which allows to exempt discussion procedures if impact on environment is found to be minimal after drafting the assessment report. In case of national-level, it has a dual system that is split between Ministry of Construction and Transportation and Ministry of Environment. However, in case of environment impact assessment of local governments, it is a single system where city mayors and provincial governors are in charge of both project execution and environmental assessment. Therefore, the most important task is how to satisfy objectiveness and accountability.

Restoration of ecosystems degraded by heavy metal pollution can be accomplished by soil amendment and selection and utilization of plants tolerant to heavy metals. Two former zinc mine sites, Sambo Mine in Hwasung, Kyonggi-do and the Second Yonhwa Mine in Samchuk, Kangwon-do, were selected for collection of plant samples and for determination of heavy metal tolerant species. Dominant species on mine waste deposits in Hwasung site were Panicum bisulcatum and Echinoch/oa crus-galli, while those in Samchuk site were Aster yomena, Setaria viridis, Artemisia lavandulaefolia and Oenothera odorata. Mean contents of zinc, lead and cadmium in Hwasung soil were 103, 117 and 1 ppm, respectively, while those in Samchuk soil were 23, 6 and 4 ppm, respectively, Zinc contents were higher in Echinochloa crus-galli from Hwasung and in Artemisia lavandulaefolia from Samchuk, while lead contents were higher in Panicum bisulcatum and Echinochloa crus-galli from Hwasung and Lactuca sonchiJolia and Pinus densiJolia from Samchuk. Plant species with higher cadmium contents were Panicum bisulcatum and Lactuca sonchiJolia. Comparison of metal contents between roots and shoots showed that Echinochloa crus-galli was a zinc accumulator, while Panicum bisulcatum, Persicaria hydroPiPer, Pinus densiJlora and Lactuca sonchiJolia were zinc excluders. In addition, Panicum bisulcatum and Persicaria hydroPiPer were proved to be lead excluders. When both heavy metal contents in plant tissues and biomass of individual plants are considered, it can be concluded that Echinochloa crus-galli and Panicum bisulcatum from Hwasung and Artemisia lavandulaefolia and Aster yomena are heavy metal absorbing plants. The effect of heavy metals on seed germination showed that Artemisia princeps var. orientalis had higher germination rates, but no significant difference in concomitant decrease of germination rates among the species investigated were found by increasing heavy metal contents.

I. Purpose This study is performed to encourage cancer patients to identify, relieve and effectively overcome the stress caused by radiotherapy, by analyzing stress reactions and coping patterns of cancer patients who perceived stress due to radiotherapy. II. Materials & Methods The study group was composed of 85 cancer patients of the age 20 or higher who were undergoing radiotherapy in four hospitals located in Seoul and Kyonggi-do. The survey questionnaire was used, which had 161 questions inquiring respondents of general status, perceived stress, stress reactions and coping patterns. The surveyed data were analyzed by a SAS program, which employed descriptive statistics. Pearson Correlation Coefficient, t-test, ANOVA and Stepwised Multiple Regression. III. Results The stress perception and reaction rates were low in cancer patients comparing to patients of the other study. In the coping patterns. the problem-focused coping patterns were significantly higher than emotion-focused coping patterns. The statistically meaningful differences were observed in the stress perception and reactions depending on the time of diagnosis and perceived health level. As for the problem-focused coping patterns, significant differences were found depending on age, marital status, education, income and the number of family members as well as perceived health level of patients. The level of perceived stress and that of stress reactions was found to have positively significant correlation(r=.764, p<.001) while the perceived stress and the problem-focused coping patterns was correlated negatively (r=-.288, p<.01). The stress reactions and the problem-focused coping patterns was found to have negatively significant correlation(r=-.289, p<.01). IV. Conclusion The problem-focused coping behavior, which cooperated with doctors, technologists, nurses and families of cancer patients, is advisable for the cancer patients to overcome uncertainty and uneasiness by effectively release the stress.
