Ulsan made its contributions to modern Korea as an industrial city. In the 1960s, Ulsan was appointed as a special industrial zone. After that, industrial complexes were built without environmental considerations so Ulsan was once called "the polluted city". However, in the early 2000s, the main concern of Ulsan's policies was gradually shifted from the economic growth to the environmental issues. In order to enhance the environmental quality and to make the Ulsan more environmentally friendly eco-city where human and nature coexist, Ulsan city declared "The Eco-polis Ulsan" in 2004 based on "The Master Plan for Eco-polis Ulsan" which included the eco-industrial park as an action plan. This study aims at defining the concepts of eco-city and policies to build Ulsan-style eco-city as environmentally friendly city and proposing Ulsan as a role model to cities and towns of developing countries. In addition, Ulsan's EIP project which will be implemented for 15 years from 2005, is elaborated including regulatory issues and technologies to be applied.

This paper aimes to analyse the housing market of Ulsan, that changed for Metroplolitan city in 1997. For the housing policy we need sufficient informations on the housing market appeared during the last five years. As a result, we can describe its housing market in a uniform way: Ulsan, compared with other cities, doesn't show varieties in households, housing type, housing conditions etc.. Concerning the housing preference, the results of our survey also show the uniformity. And the price of apartment in Ulsan moves relatively slowly to other cities.

Currently, since the total energy amount has been increased continuously, the effort for energy efficiency of apartment building is necessary. Although the previous studies have been focused on the issue. Almost studies are about the simulation by applying the energy analysis tools and a lack of studies have been conducted the data analysis about real city gas amount of apartment building. Therefore, the objective of this study is to analyze the city gas consumption difference according to the exclusive dwelling in apartment building. To address this issue, the descriptive, correlation, analysis of variance (ANOVA) statistics are used in this study. As a result, in the case of annual total amount, the city gas is increased as the size of the exclusive dwelling area is increased. In the future, the findings of this study can be used as a basic material to develop the prediction model of city gas in apartment building.

Currently, effective energy management of buildings is necessary because of accelerated global climate change and resource crisis. Especially, in the case of South Korea, city gas consumption occupies 11.8% of the total energy and 39.6% is residential use among them. Therefore, for reducing the city gas consumption, the effectiveness of residential use is needed. To address this issue, the objective of this study is to analyze the difference of the city gas consumption according to the space arrangement in the apartment building. To achieve this objective, an apartment complex having over 1,000 households was selected then, according to the space arrangement such as south-east and south-west, the data of 59.97m2 and 84.96m2 were analyzed by using statistics method. As a result, in 59.97m2 and 84.96m2, the total city gas amount in 2012 showed that 9.2% and 8.4% were more increased at south-west than southeast respectively. In the future, the findings of this study can be used to develop the prediction model of city gas consumption in apartment building.

Purpose: The purpose of this study is to investigate the heavy metal pollution of playgrounds of elementary schools in the Ulsan Metropolitan City. Soil pollution is one of the most dangerous problems of the utmost concern to both children and teachers. The result of this study would be an educational datum for improving children's health and establishing educational policy. Methods: For the analysis, fifteen representative schools were selected from five sample areas such as Dong-gu, Nam-gu, Jung-gu, Buk-gu and Ulju-gun of the Ulsan city. And from each school playground, soil was extracted from five spots and mingled into one sample. These fifteen samples were pretreated by the microwave extraction method, and the extracted heavy metals(As, Cd, Cu, Pb, Cr⁶⁺, Zn and Hg) were quantified by the ICP(Inductively Coupled Plasma) system. Results: The results of the analysis shows that the level of heavy metal pollution of elementary school playgrounds in Ulsan city did not exceed the permitted limit of each heavy metal. This means that the soil pollution of playgrounds in the Ulsan Metropolitan City is not so serious as it is expected. But it should be added that the soil is not too safe to be ignored.

Invasive alien plants were identified and recorded in Ulsan city based on field surveys and related literatures. These plants consisted of 147 taxa in total, belonging to 30 families, 93 genera, 144 species, 2 subspecies and 1 variant. The family of Asteraceae was predominant with 42 taxa, followed by Gramineae with 27 taxa and Leguminosae with 15 taxa. According to the result of life-form based distribution analysis revealed that 62 taxa (42.2%) were annual plants, 48 taxa (33.6%) were perennial plants, 34 taxa (23.1%) were biennial plants, and 3 taxa (2%) were woody perennials. Compare to other administrative districts in Korea, prevalence of invasive alien plants in a certain city of Ulsan showed the seventh highest species number followed after Jeju, Gyeonggi, Jeonnam, Incheon, Seoul and Gangwon. On the basis of the results from the country origin analysis, two dominating taxa were introduced from Europe and America, 55 taxa and 51 taxa respectively. The spreading grade of alien plants was elucidated in order of 1 grade (PS) 67 grade (21.1%)>2 grade (MS) 31 taxa (21.1%)>5 grade (WS) 18 taxa (11.6%)>3 grade (CS) 17 taxa (11.6%)>4 grade (SS) 14 taxa (9.5%). Ulsan city is one of a pivotal conduit for the introduction of invasive alien plants. Thereby, reliable management plans are required to monitor these species.

Purpose: Currently, since the energy consumption of apartment buildings is on the rise, it is necessary to reduce the total amount of the energy through the survey and analysis of energy consumption data. Although various studies for energy efficiency have been conducted, studies are more focused on the measurement of energy by using analysis tools. In addition, the studies are sufficient to analyze real data of the city gas in apartment buildings. Therefore, the objective of this study is to identify the property of annual and $1m^2$ city gas amount according to the exclusive dwelling area. Method: To achieve the objective, this study used the statistics such as descriptive, correlation, and analysis of variance (ANOVA) analysis. Result: As a result, there is positive relationship between the annual average of city gas and the exclusive dwelling area. However, in the case of $1m^2$ city gas amount, a negative relationship is mored. In the future, the findings of this study can be applied to develop the prediction model of the city gas consumption and implement it as basic data for energy efficiency of apartment buildings of future.

The purpose of this study is to examine the effects of park type and inner elements of parks on the number of walking days of walking out of Ulsan Metropolitan City, And to make policy suggestions for them. The elderly people aged 65 and 1,274 persons or over in Ulsan Metropolitan City were selected as the subjects using the raw data of the 2015 community health survey. A multilevel analysis was conducted using a hierarchical linear model to find out the factors affecting the number of days of walking according to the level of regional level factor according to the five wards of Ulsan Metropolitan City. The number of walking days increased with the number of sports facilities and the number of walking days decreased with the number of amusement facilities mainly used by children. In the case of Jung-gu in Ulsan, the number of walking days was low even though the number of parks and the area of the park were large, In the case of Buk-gu, the number of walking was high even though the number of parks and the area of the park were small. Elderly people in Jung - gu, Ulsan metropolitan city are expected to need a health promotion project to promote walking, and it is necessary for seniors in Buk - gu, Ulsan Metropolitan City to make a good walking environment.
