  • This landscape design proposal was presented to a design competition for the Culture.Welfare.Administration Complex of Yongin-City which was held by Yongin-City in December, 2001. The site is located at 68-19 Yukbuck-dong, Yongin-City, Kyunggi-do and has an area of 236,449$m^2$. The judging criteria for landscape design set by the Yongin-City could be articulated as follows: an environment friendly design respecting the surrounding environment, a locale as a community center of Yongin-City, a resting place for the welfare of employees and visitors, and finally a place with diverse landscape elements reflecting the individual identity of each facility. This proposal chose the main design concept of this project as‘Nature meets City'. A grove of pine trees fragments the multi building complex, so that‘nature'was brought into the‘city'. A double ground system was introduced to respect the existing topography and to enhance the efficency of the land. This design proposal consists of four segments. Each segment has its own design theme. Outdoor space of this multi-purpose complex was designed with themes of nature, culture, welfare and administration. Space composition with grid and natural looking curvilinear lines was a design motive for this complex. The nature oriented planting design was introduced to respect the existing groves of Mt. Suksung. Specific species were chosen to follow its own spatial character in each space. An environmental sculpture called‘Dream Soaring'was placed in the middle of‘Citizen Plaza'. Its light and feather-looking shape symbolizes the vision of Youngin-City. At night people can watch the diverse color changes on its mirror-like surface.

  • This study was carried out to develop the close-to nature construction technology for the stream which has been improved just for the flood control with artificially straightened and concrete covered, losing the various functions of the stream such as wild-life habitat, polluted water purification and waterscape. Jungpyung stream in youngin City, Kyunggi Province was selected as a case study site. The results were as follows; 1. Existing stream improvement planning could accept the close-to-nature techniques of the low-flow revetment, keeping the capability of flood control and water use. 2. The low-flow revetment was planned and executed to the bottom of the stream without damaging the existing bank, and the slope of the low-flow revetment was adjusted as 1:1.2∼1.5. Consequently it would not disturb the water flow when the flood occurred and it would keep the constant water flow even at the drought with providing a stable ecosystem and water purification. 3. Low-flow revetement was planted with Salix species and perennials naturally, and it would be a precious biotope for the diverse floras and faunas. 4. Some furnitures such as stepping stone bridge, wooden bridge and step were installed to the suitable locations for the convenience of users, and it will be ot only the sound stream environment but also easy access to the waterscape. 5. This case study site will be monitored for 3 years systematically after the construction was finished in September, 1999 to get the exact results for the scientific approvement

  • Objectives: Preservatives, suspected to be endocrine disrupting chemicals, are widely used in feminine hygiene products for the prevention of deterioration. Information regarding the usage patterns of feminine hygiene products and the concentrations of preservatives in these products is limited. The present study was conducted to investigate the use of feminine cleansers among Korean women and quantify the concentration of preservatives in feminine cleansers. Methods: Approximately 500 women were recruited from the city of Busan in August 2017 and a questionnaire survey was conducted on the use of feminine cleansers. Several major feminine hygiene products (n=69) were identified and selected for analysis of 22 preservatives. Following appropriate preparation, the products were analyzed by HPLC/DAD. Results: Over 70% of the participating women used at least one feminine cleanser. Marital status and parity were associated with the frequency of use. Liquid was most frequently used form of feminine cleanser (66.6%). The greatest proportion of subjects answered that they use it 'one to two times per week' (36.5%). Among the 69 feminine cleansers, benzoic acid, sorbic acid, phenoxyethanol, and methyl paraben were detected at $144-4,428{\mu}g/g$, $195-1,470{\mu}g/g$, $269-4,237{\mu}g/g$, and $625-4,901{\mu}g/g$, respectively. BA was the most frequently detected (46.4%). Conclusions: In the present study, the characteristics of feminine cleanser use among Korean women were investigated. Based on an analysis of preservatives in the feminine hygiene products, one product was determined to exceed the maximum authorized concentration of MeP (0.4%). Our results will help refine exposure and risk assessment for toxic chemicals in feminine cleansers.

  • In case of a fire in road or railway tunnel it is always necessary to keep the escape condition as good as possible. Most of the victims of major fires in tunnels are because they couldn't leave the tunnel in time and were trapped by smoke, or rescue teams couldn't reach the place of the accident due to low visibility and high temperature. In spring 2003 a comprehensive field experiment was undertaken in a large scaled tunnel in Youngin City to test the effectiveness of a new water spray curtain system, designed to the air qualify inside of a tunnel in case of fire during passenger's escape to safe routes, In order to control the smoke propagation, fixed water sprayed nozzles were used to make water curtain system, which can be installed or hanging water piping line below ceiling. The experiment was accompanied by an extensive measurement campaign in order to measure temperature dropping effect and flow conditions as well as CO concentration for various water sprayed curtains produced by sprinkler heads or water spray nozzle. Eventually comparison analysis were undertaken to investigate the performance of water curtains under fixed water pressure. Therefore most effective water curtain system was presented on the basis of water droplet size in long tunnel.

  • Instroduction: The purpose of this study was to investigate safety education-related backgrounds and safety behaviors of elementary school children at a local area in Jeonbuk province. Methods: Study subjects were 308 5th and 6th graders from 6 schools located in J City and the data were collected from June 16-27, 2003. Research instrument to test safety behaviors was 4-points summated scale (Cronbach${\alpha}$= .94) composed of 54-items with three sub-categories school life safety (${\alpha}$= .88), traffic safety (${\alpha}$= .86), and daily life safety (${\alpha}$= .84), The data was analyzed by percentage, x2-test, t-test, ANOVA and Duncan test using SPSS/PC 10.0. Results: 1. Safety Education-related Characteristics: Safety education was mostly conducted during extracurricular hour as picnic (37%) and regular class (37.2%); and the instructors of safety education were school nurse (33.2%), classroom teacher (30.9%), and parents (23.4%) in order. About two third (71.0%) of the subjects have had many kinds of school event program such as essay writing, poster drawing, oratorical contest in the course of safety education According to gender, girl students was more favorable about school events as a effective safety education measure (x2=9.188, p= .010); and according to school location, nural school taught more at moming & closing session (x2=7.383, p= .025), by school nurse or classroom teacher (x2=36.574, p= .001), and had more frequent (x2=63.337, p= .001) safety education class. 2. Practice of safety behaviors: Mean scores of safety behaviors was $106.9{\pm}24.92$ out of 162 points. According gender, the scores of girl students (t=-3.296, p= .001) were significant higher than boy students. But there was not any significant difference according to school area According to safety education-related characteristics, the scores of safety behaviors was significantly higher in the group who thought that school event program was more effective on safety education (F=4.024, p= .019), and who were more interested in current safety education class (F= 10.203, p= .001) Conclusions: From the above findings, the authors concluded that school-based safety education was mainly conducted at extra-curricular and regular class, and by school nurse or classroom teacher in elementary school. Even though the mean scores of safety behaviors of elementary school children was in medium level, those. were significant higher in girl students and in rural school children. And extra-curricular activities and school event programs were suggested as more effective strategies for school-based safety education Based on the above findings, safety education class can be recommended in regular curricular basis; and various extracurricular activities and school event programs need to be developed for more effective school-based safety education. In addition, further study on gender-specific factors on safety behaviors and nationwide survey on school-based safety education should be needed.

  • The urban is possessing of various landuses such as commercial, industrial, residential and official areas. All of these landuses is including the paved areas that are roads and parking lots. The NPS (nonpoint sources) pollutants are generally originated from pavement areas in urban by human activities. Especially the roads are stormwater intensive landuses because of high vehicle activities and high imperviousness. The main NPS pollutants from roads are particulates and metals from vehicles and pavements. The Korea MOE (Ministry of Environment) is developing the NPS control program to reduce the NPS pollutants from the basins. However, it is not easy to control the NPS because it has high uncertainty by characteristics of rainfalls and watersheds. Therefore, this research was conducted on characterizing the runoff and providing mean EMC from roads. The monitoring were performed for total 16 rainfall events from a road in Youngin City since 2006. The results show that the TSS is highly correlated with other pollutant parameters. The statistical regression models using TSS EMC have been developed to easily determine the EMC of other pollutant parameters.
