Scrophularia takesimensis Nakai called 'Sum-Hyun Sam' growing about 1m in high is a perennial plant of Scrophulariaceae. Because the number of these species is very limited in the world, the Ministry of Environment has appointed S. takesimensis as a preserved plant. The Korea Forest Service also protects it strictly by the law since S. takesimensis is an out-of-the-way plant and possible to be exterminated soon in Korea. Investigation for distribution and ecological characteristics of the habitat far S. takesimensis was carried out in Ulleung-do Island. S. takesimensis has a tendency to emerged with Calystegia soldanella Roem. et Schultb. and Artemisia japonica subsp. littoricola Kitam. C. soldanella community were developed on the dry and well-lighted as east or north facing conditions. A. japonica subsp. littoricola community have tendency to developed on the properly lighted as west or north facing and well maintained soil or air humidity. C. soldanella community were developed on the sandy gravel or gravel and grew with Farfugium japonicum, (L.) Kitam., Lonicera japonica Thunb., and Peucedanum japonicum Thunb.. A japonica subsp. littoricola communities were emerged on the rock beds or pile of rocks and grew with Sedum oryzifolium Makino, Sedum takesimense Nakai, and Spergularia marina (L.) Griseb.

To investigate the effects of electro-acupuncture (EA) treatment on regions remote from the application, we measured cellular, enzymatic, and transcriptional activities in various internal tissues of healthy rats. The EA was applied to the well-identified acupoint ST36 of the leg. After application, we measured the activity of natural killer cells in the spleen, gene expression in the hypothalamus, and the activities of antioxidative enzymes in the hypothalamus, liver and red blood cells. The EA treatment increased natural killer cell activity in the spleen by approximately 44%. It also induced genes related to pain, including 5-Hydroxytryptamine (serotonin) receptor 3a (Htr3a) and Endothelin receptor type B (Ednrb) in the hypothalamus, and increased the activity of superoxide dismutase in the hypothalamus, liver, and red blood cells. These findings indicate that EA mediates its effects through changes in cellular activity, gene expression, and enzymatic activity in multiple remote tissues. The sum of these alterations may explain the beneficial effects of EA.

In this paper, the autonomous mobile robot whit only LRF sensors proposes an algorithm for avoiding moving obstacles in an environment where a global map containing fixed obstacles. First of all, in oder to avoid moving obstacles, moving obstacles are extracted using LRF distance sensor data and a global map. An ellipse-shaped safety radius is created using the sum of relative vector components between the extracted moving obstacles and of the autonomuos mobile robot. Considering the created safety radius, the autonomous mobile robot can avoid moving obstacles and reach the destination. To verify the proposed algorithm, use quantitative analysis methods to compare and analyze with existing algorithms. The analysis method compares the length and run time of the proposed algorithm with the length of the path of the existing algorithm based on the absence of a moving obstacle. The proposed algorithm can be avoided by taking into account the relative speed and direction of the moving obstacle, so both the route and the driving time show higher performance than the existing algorithm.

We incubated marine columnar sediments at $25^{\circ}C$ for 230 days to simulate the responses of phosphorus in the sediment which was exposed to freshwater. The incubation was composed of three different treatments (FW: freshwater, FWA: freshwater under anoxic condition, and SW: seawater as a Control). Six particulate fractions of phosphorus in sediment were obtained through sequential extraction and, for comparison, phosphate concentrations in porewater and superlying water were also determined. After the incubation, evidently higher concentrations of phosphate were found in FW and FWA compared to SW. Mass extinction of living organisms in marine sediment from freshwater shock and consequent decay of their corps probably contributed such high phosphate spike in the overlying water. Higher concentrations of BD-P(lron-bound P) were found in FW compared to SW. After exposure to the freshwater, we could determine that penetration depth of dissolved oxygen in marine sediment will be deeper. A result of increases of ferrous compounds in freshwater where contained less sulfide has been obtained. Because of these phenomena, BD-P was increased in FW. On the contrary, BD-P was decreased in FWA since poor dissolved oxygen concentration. In FWA, total amount of Leachable P(SUM of LOP) has been remarkably increased through the experiment, which strongly suggested the easy conversion of the leachable P into reactive P. This experiment has shown that most of diverse P species in marine sediment were leachable under freshwater and low oxygen condition. Therefore reclamation of natural tidalfalt and consequent freshwater introduction seems to trigger the conversion of diverse P-species to leachable P in the marine sediments, which will exert high benthic load of phosphate to the overlying water.
