  • Environmental education, which has been thought as the most fundamental solution to environmental problems, should be performed not only in school but also in home and society with a long-term plan. In line with this, environmental-friendly attitude in daily life should be achieved by the perception of the vital environmental principle-new understanding of relation between nature and human being. It is in the city park that children in urban area, who has little opportunity to contact nature, have rather easier access to nature and realize the principle. Despite such great potential, the city park in Korea has not played its pivotal role because of lack of both facilities and activities. In addition, existing studies on this issue are not satisfactory. Therefore, this study is aimed at analyzing and evaluating city parks' environmental education function, potential and problems according to their types, then offering practical reform measures and programs in order to make students better understand the parks as an everyday natural experience spot. These plans are not based on full-scale revision, instead focuses on optimizing potential of existing natural environment and parks. Additionally, activities to experience various nature are included in the study. The value of city park is not decided by the park itself, but by its relationship with visitors. Environmental education function of city park is not confined to building up facilities and providing programs. It also should be complemented and improved, reflecting visitors' opinions and evaluation of environmental education.

  • Luteolin is a plant flavonoid which exhibits anti-oxidative, anti-inflammatory and anti-tumor effects. However, the antiproliferative potential of luteolin is not fully understood. In this study, we investigated the effect of luteolin on cell cycling and apoptosis in human esophageal squamous carcinoma cell line Eca109 cells. MTT assays showed that luteolin had obvious cytotoxicity on Eca109 with an $IC_{50}$ of $70.7{\pm}1.72{\mu}M$ at 24h. Luteolin arrested cell cycle progression in the G0/G1 phase and prevented entry into S phase in a dose- and time-dependent manner. as assessed by FCM. Luteolin induced apoptosis of Eca109 cells was demonstrated by AO/EB staining assay and annexin V-FITC/PI staining. Moreover, luteolin downregulated the expression of cyclin D1, survivin and c-myc, and it also upregulated the expression of p53, in line with the fact that luteolin was able to inhibit Eca109 cell proliferation.

  • Two ennomine species, Amblychia angeronaria Guen$\acute{e}$e and Peratostega deletaria (Moore), are reported for the first time from Korea. Amblychia angeronaria was collected from Isl. Gageo-do, in the south west of Korea. The species is distinguished by the large wingspan, the ochreous forewing with a row of large white dots on the postmedian and a grayish apical dot, and the grayish or dark ochreous hindwing with undulating postmedial line and dark grayish subterminal line. Peratostega deleraia was collected from Isl. Jeju-do, and can be distinguished by the dark brown forewing with a blackish dentate postmedian and a light brown apical dot, and the dark brown hindwing with the light brown subtermen and angulate termen. Diagnosis and description of the species are given along with figures of the male and female genitalia.

  • This study examined the relationship between Phragmites australis' growth and sediment properties at mud tidal flat of Donggum-ri, Gilsang-myeon, Gangwha-gun, Incheon city. Field survey was carried out from May, 2010 to October, 2010. Water content, soil texture, electric conductivity and water table depth for sediment, density, height, dry weight and flowering for P. australis were examined at several plots from the starting point (the coastal embankment) to the end point of the two populations. The result was as follows. Firstly, the water table increased along distance from the embankment at one line (N-line) but was similar at the other line (S-line) in a P. asustralis population. Water tables were higher out of than within a P. australis population at two populations. Secondary, in N-line, the height and dry weight of P. australis decreased along the distance from embankment but, in S-line, those were similar in its population. P. australis' growth was dependent on electric conductivity at lower layer (water table level) rather than upper one (the surface). Thirdly, density of P. australis changed during growing season and was similar in a population, except for the end point of patch. In summary, the growth and distribution of P. australis were dependent on salt content of tidal flat's sediment (water table level) and this was affected by fresh water of the inland.

  • Two species of Scopula, S. asthena Inoue, 1943 and S. tenuisocius Inoue, 1942, were newly recorded from Korea. Scopula asthena can be distinguished by the bipectinate male antennae and whitish wings with four blackish dots on each wing. This species is similar to S. superior (Butler, 1878) but differs in the large blackish discal dots on both wings. Scopula tenuisocius can be distinguished by its whitish forewing with light grayish, dentate antemedial line, short-line shaped discal dot and line light grayish, weakly rounded, dentate postmedial line, and whitish hindwing with a blackish discal dot and light grayish, undulating medial lines. Scopula tenuisocius is similar to S. floslactata (Haworth, 1809) but the species can be distinguished by the thinner and blackish subterminal line of the forewing that appears minutely dentate along the line. To date, 41 species of the genus Scopula are known in Korea.

  • The dipole-dipol electrical resistivity survey was conducted to investigate the probable contamination of the Han river by leachate from the near-by Nanjido Landfill. The survey line of 3 km was set along the unpaved road toward the Han river. For the convenience of the field work, the survey line was divided into four segments. The complete two-dimensional resistivity section was constructed by connecting the inversion result of each segment. Gravity survey was also carried out along the profile parallel to the resistivity line. Near surface resistivity generally appeared to be of very low value in most part of the survey area and the boundary between the alluvium layer and underlying basement rocks is well discriminated on the resistivity section. These results agree well with those of the preceding Schlumberger depth sounding made at adjacent area by Lee and fun (1995). The variation of thickness of the alluvium layer delineated by gravity anomaly profile also correlates well with the result of the resistivity survey on the qualitative basis. The problem of contamination by leachate from the Nanjido Landfill, where various waste materials have been dumped without any proper treatment facilities, has been remains unsolved yet. Therefore, we present the most probable passages of leachate flow based on the survey results and have briefly discussed about measure for contamination control. Considering the thickness of alluvium and the possible existence of fractured zone, the middle point between 1st and 2nd landfill and the midst of 1st landfill are the most hazardous regions to make leachates flow into the Han river. Since large amounts of leachates are observed from the test wells located on the lines extending from the border between the 1st and 2nd landfill and the middle of the lst landfill, contamination protection barriers are strongly recommended near these regions.
