  • To select some salt tolerant pasture species for grassland establishment on the west coastal saline land in Korea, this work was carried out from March to October in 1976 with 5 pasture seeds mainly were introduced from Australia. On the soil salt content was 0.4%, all seeds germination were failure, but all species were survived on the 0.2% salt content land. The yield of forage were much better from Kikuyu grass and Pearl millet but poor from other species. The Meadow grass could be used for protect soil erosion by lot of tillers. By the result from this experiment, only Kikuyu grass and Pearl millet were possible to use for forage crops. But to continue this work, it is suggested to introduced more effective species such like Saltwater couch, Saltshore ryegrass, Puccinella, Salt bush, Blue buch, Samphire and so on.

  • A stochastic numerical analysis for predicting the groundswater fluctuations in hillside slopes is performed in this paper to account for the uncertainties associated with the rainfall and site characteristics. The effect of spatial variabilities of aquifer parameters and the effect of temporal variability of recharge on the groundwater fluctuations are studied in depth. The Kriging is used to account for the spatial tariabilities of aquifer parameters. This technique prolevides the best linear unbiased estimator of a parameter and its minimum variance from a litsitem number of measured data. A stochastic one-dimensional numerical model is delreloped b) combining the groundwater flow model, the Kriging, and the first-order second-moment analysis. In addition, a two dimensional detelministic groundwater model is developed to study the change of ground water surfas in the transverse direction as well as in the downslope direction. It is revealed that the undulations of the impervious bedrock in addition to the permeability and the specific yield have an important influence on the fluctuations of the groundwater surface. It is also found that th'e groundwater changes significantly in the transverse direction as well as in the downslope direction. The results obtained in this analysis may be used for evaluation of landslide risks due to high porewater pressure.

A Study on Enhancing the Level of the Self-containment of New town in the Capital Region, Korea -The case study of Ilsan from the viewpoint of ESSD- (수도권 신도시의 자족성 제고 방안 -ESSD관점에서의 입산신도시 사례분석-)

  • The purpose of this study is to review the meaning of the self-containment of new town from the viewpoint of ESSD and to derive some policy implications for enhancing the level of the self-containment. The case study area selected for empirical research is Ilsan in Seoul Metropolitan Area. As the self-containment of a new town is related to the energy consumption in transport and the increment of air pollution, the behavioral analysis of residents using self-contained facilities is one of the important subjects in ESSD. So, in this paper the characteristics of the land use plan and the level of self-containment in Ilsan new town are analyzed with regard to the supply of schools, jobs, goods and services. The empirical study shows that the degree of self-containment in the supply of jobs has low score(21.8%) because Ilsan new town is involved in the region in which the provision of a variety of employment opportunities is restricted by the metropolitan arrangement plan. The degree of self-containment in the supply of schools and goods has high score(94.0% and 89.4%). But there is a time lag in the supply of public services. It is suggested that new towns must be located remote from Seoul to avoid the restrictions by the metropolitan arrangement plan. To bring up the self-contained facilities, it is desirable to draw up a plan of attracting the tertiary sector in new town such as office industry. And, as the office industry prefers to locate in CBD of central city, it is necessary to give financial incentives to relocate the industry to new town. The establishment of an office complex for the pursuit of agglomeration economy would be an appropriate alternative. To solve the problem of time lag in the supply of self-contained facilities, it is necessary to prepare the synchronized development plan of housing and convenience facilities, especially schools and public services.

  • This article discussed whether so-called 'foreign judgments obtained by fraud' is in breach of public policy provided in Article 217(1)(3) of Civil Procedure Act and, if so, what the specific requirements could be. The summary of the conclusion is as follows. The 'foreign judgments obtained by fraud' is against the municipal procedural public policy and then shall not be recognized. In this regard one more question comes up whether reviewing if 'foreign judgments obtained by fraud' is in breach of the municipal procedural public policy is allowed in consideration of the principle of prohibition of $r{\acute{e}}vision$ au fond. Since the principle is applied entirely in the course of the above reviewing, it is allowed only when it does not breach the principle. The two instances that the reviewing is allowed are where the defendant was not able to produce evidences of fraud during foreign procedures and where the defendant's claim of fraud without evidences was rejected by the foreign court and then evidences of fraud were found after the foreign procedure was completed. On the other hand, the specific requirements for 'foreign judgments obtained by fraud' to be against public policy are following four requirements based on principle of strict interpretation of public policy. (1) plaintiff's intention to fraud, (2) preventing the defendant from being involved in the procedure by fraud or cheating the foreign court using manipulated evidences, (3) the defendant could not present himself in the foreign court procedure due to the plaintiff's extraneous fraud or the foreign court decided wrongly due to intrinsic fraud, and (4) defendant's fundamental procedural rights were breached to the extent that recognizing the effect of foreign judgments was against justice defendant's fundamental procedural rights. These results differ from the Supreme Court 2004. 10. 28. ruling 2002da74213 in many aspects. Most of all, in my opinion there is no need to distinguish between intrinsic fraud and extraneous fraud and reviewing 'foreign judgments obtained by fraud' is not in conflict with the principle of prohibition of $r{\acute{e}}vision$ au fond but the both may coexist. In this regard I expect the variation of the Supreme Court's position and hope to contribute to academia and practitioners.

  • Skin carrys out protective role against harmful outer environment assaults including ultraviolet radiation, heavy metals and oxides. Especially, ultraviolet-B (UVB) light causes inflammatory reactions in skin such as sun burn and erythma and stimulates melanin pigmentation. Furthermore, the influx of UVB into skin cells causes DNA damage in keratinocytes and dermal fibroblasts, inhibition of extracellular matrix (ECM) synthesis which leads to a decrease in elasticity of skin and wrinkle formation. It also damages dermal connective tissue and disrupts the skin barrier function. Prolonged exposure of human skin to UVB light is well known to trigger severe skin lesions such as cell death and carcinogenesis. Haloarcula vallismortis is a halophilic microorganism isolated from the Dead Sea, Its growth characteristics have not been studied in detail yet. It generally grows at salinity more than 10%, but the actual growth salinity usually ranges between 20 to 25%. Because H. vallismortis is found mainly in saltern or salt lakes, there could exist defense mechanisms against strong sunlight. One of them is generation of additional ATP using halorhodopsin which absorbs photons and produces energy by potential difference formed by opening the chloride ion channel. It often shows a color of pink or red because of their high content of carotenoid pigments and it is considered to act as a defense mechanism against intense UV irradiation. In this study, the anti-inflammatory effect of the halophilic microorganism, H. vallismortis, extract was investigated. It was found that H. vallismortis extract had protective effect on DNA damage induced by UV irradiation. These results suggest that the extract of halophilic bacterium, H. vallismortis could be used as a bio-sunscreen or natural sunscreen which ameliorate the harmful effects of UV light with its anti-inflammatory and DNA protective properties.
