This research aims to grasp the use status and satisfaction level based on citizen consciousness in night time to improve future design. This study employs a combination literature review and field survey. In the literature review, the related materials were collected to obtain the most useful information for references, and the POE study of the Bomunsan Park was conducted. The survey instrument is a questionnaire that includes questions regarding Bomunsan Park. Data were analyzed using the Statistical Package for the Social Sciences(SPSS17.0 for Windows). Through the POE analysis of the usage status and variables which significantly affect the users’ degree of satisfaction with the spaces and facilities were investigated and the following problems have been found. Bomunsan Park requires extensive modification to meet the demand of citizens. Several shortcomings are hampering the development of the Park. The rest space and the nightscape seem to be the two most problematic aspects in the Park. The nightscape design should be particularly emphasized in the overall park design in the future. Usage night and space and facilities for user satisfaction analysis, the increase of bus routes and the lighting was the biggest problem. Therefore, future access to transportation means and at night design considerations will be based on the need to plan.

The purpose of this study is to find out Landscape Change Analysis of Forestland Using NDVI of Landsat TM on Suwon, Anyang, Sungnam, Ansan City as the subject of investigation. The characteristics of landscape change of them are as follows : 1. As a result of landcover classification in each area, the forestland decressed by 22.8% in Ansan, 21.2% in Suwon, 3.7% in Anyang and 3.1% in Sungnam. 2. By the change of landscape in NDVI indicated by band4 and band3 of Landsat TM, total incresmemt is Suwon(0.0155), Anyang(0.0239), Sungnam(0.0371), Ansan(0.0049) in 1993. therefore the quality of vegetation seems to be analysized as Sungnam > Anyang > Suwon > Ansan city. 3. In the 6, 7 level of NDVI which is very importance in enviromental impact asscesment, it is indicated that the place of some problem about landscape management in ecological health is Ansan city a mong of them because the area of that decreased in NDVI.

An experimental investigation has been performed to determine optimal conditions for preparing the thermoluminescent CaSO_(4):Dy pellets which have been widely used as personal radiation dosimeter material. Our investigation has shown that an optimal weight concentration of the dopant Dy in the bulk CaS0_(4):Dy is 0.1 mol%. and an optimal temperature of adding Dy in the preparing process is 320℃. An optimal time and temperature for sintering the CaSO_(4):Dy crystal produced from the chemical process are found to be 2 hours and 800℃. respectively. The maximum thermoluminescent sensitivity was observed when the CaSO_(4):Dy crystal was pulverized to grain sizes of 63 - 200 m in diameter before being fabricated into pellets. The commercial Teflon was selected as an adhesive for the fabrication of the CaSO_(4):Dy pellets with an optimal mixing ratio of the Teflon and CaSO_(4):Dy being 70 to 30 in weight.

급성 심근염환자에서 발행한 완전 방실차단을 영구 심장박동 조율기로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Myocarditis, an inflammatory process involving the myocardal wall, may be caused by most infectious agents. Irrespective of its etiology, it presents commonly with evidence of heart failure, hypotension, and various electrocardiographic abnormalities. Patient with myocarditis may be asymptomatic or may have a rapidly progressive fatal disease. Medical management of patients with myocarditis includes specific therapy for underlying infection and control of the complication of myocarditis such as congestive heart failure and arrhythmia. Recently we had experienced myocarditis with complete atrioventricular block in 37-year-old man. Although he had shown complete recovery of heart failure, he had shown complete atrioventricular block, so we inserted permanent pacemaker. We report it with review of the literature.

Melatonin suppresses tumor angiogenesis by inhibiting HIF-1&agr; stabilization under hypoxia

Park, Shi-Young,Jang, Won-Jun,Yi, Eui-Yeun,Jang, Ji-Yeong,Jung, Yunjin,Jeong, Joo-Won,Kim, Yung-Jin Blackwell Publishing Ltd 2010 Journal of pineal research Vol.48 No.2

<P>Abstract: </P><P>Angiogenesis is an important mediator of tumor progression. As tumors expand, diffusion distances from the existing vascular supply increases, resulting in hypoxia in the cancer cells. Sustained expansion of a tumor mass requires new blood vessel formation to provide rapidly proliferating tumor cells with an adequate supply of oxygen and nutrients. The key regulator of hypoxia-induced angiogenesis is the transcription factor known as hypoxia-inducible factor (HIF)-1. HIF-1&agr; is stabilized by hypoxia-induced reactive oxygen species (ROS) and enhances the expression of several types of hypoxic genes, including that of the angiogenic activator known as vascular endothelial cell growth factor (VEGF). In this study, we found that melatonin, a small lipophilic molecule secreted primarily by the pineal gland, destabilizes hypoxia-induced HIF-1&agr; protein levels in the HCT116 human colon cancer cell line. This destabilization of HIF-1&agr; resulted from the antioxidant activity of melatonin against ROS induced by hypoxia. Moreover, under hypoxia, melatonin suppressed HIF-1 transcriptional activity, leading to a decrease in VEGF expression. Melatonin also blocked in vitro tube formation and invasion and migration of human umbilical vein endothelial cells induced by hypoxia-stimulated conditioned media of HCT116 cells. These findings suggest that melatonin could play a pivotal role in tumor suppression via inhibition of HIF-1-mediated angiogenesis.</P>

Cannibalism in the Korean Salamander (Hynobius leechii: Hynobiidae, Caudata, Amphibia) Larvae

Park, Shi-Ryong,Jeong, Ji-Young,Park, Dae-Sik The Korean Society for Integrative Biology 2005 Integrative biosciences Vol.9 No.1

Cannibalism plays important roles at the levels of both individual and population. To enhance overall rate of successful survival and reproduction, salamander larvae may have evolved to consume both conspecifics and heterospecifics. Consuming conspecifics could result in decreased inclusive fitness possibly by killing relatives. In several salamander species, discrimination of salamander larval siblings from non-siblings and heterospecifics to avoid such a risk has been reported. To determine whether the Korean salamander larvae consume non-siblings more often than siblings and to analyze prey preferences of the salamander larvae in several different experimental conditions, a series of foraging experiments was conducted in the laboratory. We found that 1) large cannibal larvae preyed on small sibling more often than small non-sibling in a mixed group of sibling and non-sibling, 2) cannibal larvae prefered to consume live, weak, and small larvae to dead, healthy, and large larvae, and 3) cannibal larvae consumed heterospecific tadpoles more often than conspecific nonsibling larvae in a mixed group. In addition, the larval density was positively correlated with the occurrence of spacing behavior, one of the agonistic predator behaviors among salamander larvae.
