This study proposed the planting plan for sand dune restoration and simulated sand dune landscape for visual impacts prediction of restoration. The study areas are sand dune in Shindu-ri and salt marsh in Hogok-ri. And major research results are as follows; First, selection of planting materials through the investigation of local vegetation. Second, development plan of the site for ecotourism and environmental education. Third, landscape simulation study to predict the visual impacts of restoration works on coastal landscape.

This study investigates possibilities of restoring disturbed coastal landscapes. The study area is Soon-Chun Bay, Chun-Nam Province, greater part of which is dammed and turned into rice paddy. It is proposed to build sand dunes and salt marches far inside the dam, and much of the rice paddy and the dam should be restored as natural tidal flat. A hypothetical restoration plan and a planting plan are proposed. Also, a visual simulation of the restoration plan, using a photo montage technique, is presented.

Coastal landscape management guidelines and a model for evaluation of wildness of coastal landscapes were proposed. Coastal landscape management guidelines were proposed for vegetation, drainage, soil, water quality, ecological sustainability, and visitors. A model for evaluation of wildness of coastal landscapes is based on analyses of developments such as roads along the coast, land use, population, recreational developments, vegetation, wildlife, water quality, scenic beauty, cultural heritages, and so on. By the summation of the analyses, coastal areas were suggested to be divided into four zones, and management guidelines for each zone were proposed.

This study intends to find out what manmade elements in typical moderately disturbed coastal landscape are most adversely affecting its aesthetic quality. Simulation photos including a combination of five most common manmade structures (houses, roads, power lines, embankments, and aquaculture facilities) found on coastal areas were made, and thirty eight subjects in the field of landscape architecture and forty eight average subjects were asked to evaluate their visual preferences of the 32 simulation photos using seven levels of Likert scale. Overall, average and professional subjects did not show significant differences in their evaluations. Visual preferences were greatly influenced by the presence of the manmade structures. A natural coastal landscape without any manmade structures was most preferable, and a disturbed coastal landscape by all five manmade structures was least preferable. Power lines had the most serious negative impact on the landscape, and followed by the embankment. In coastal landscape restoration works and management, priority needs to be given to these manmade structures which have bigger negative landscape impacts.

This was a 2nd-year study aiming at developing the procedure of alternative system that was intended to restore not only biophysically disturbed areas but also psychologically and socially damaged community. It was suggested that this participatory restoration system could be constructed based on integrative categorization processes consisting of damage types and readiness of local residents for participation. Three case study sites-High-One resort, Lafarge-Halla cement, and high-altitude farmland near Gangneung city, were selected to apply the theoretical framework proposed as a result of 1st-year work. In order to develop introductory programs, key concepts such as forest for future, carbon offset forest, and healing forest, have been suggested based on analysis of 6 system components including human resources, communication, legal and institutional support, financial sources, restoration methods, and activity programs for each site. More detailed processes and procedures can be identified, defined, and refined after the end of final, 3rd-stage of the study in April of 2010.

<P> We explore the question of whether adenosine 5 -triphosphate (ATP) acts as an excitatory neurotransmitter in guinea-pig gastric smooth muscle. In an organ bath system, isometric force of the circular smooth muscle of guinea-pig gastric antrum was measured in the presence of atropine and guanethidine. Under electrical field stimulation (EFS) at high frequencies (>20 Hz), NO-mediated relaxation during EFS was followed by a strong contraction after the cessation of EFS (a "rebound-contraction"). Exogenous ATP mimicked the rebound-contraction. A known P<SUB>2Y</SUB>-purinoceptor antagonist, reactive blue 2 (RB-2), blocked the rebound-contraction while selective desensitization of P<SUB>2X</SUB>-purinoceptor with α,β-MeATP did not affect it. ATP and 2-MeSATP induced smooth muscle contraction, which was effectively blocked by RB-2 and suramin, a nonselective P<SUB>2</SUB>-purinoceptor antagonist. Particularly, in the presence of RB-2, exogenous ATP and 2-MeSATP inhibited spontaneous phasic contractions, suggesting the existence of different populations of purinoceptors. Both the rebound-contraction and the agonist-induced contraction were not inhibited by indomethacin. The rank orders of agonists potency were 2-MeSATP > ATP ≥ UTP for contraction and α,β-MeATP ≥ β,γ-MeATP for inhibition of the phasic contraction, that accord with the commonly accepted rank order of the classical P<SUB>2Y</SUB>-purinoceptor subtypes. Electrical activities of smooth muscles were only slightly influenced by ATP and 2-MeSATP, whereas α,β-MeATP attenuated slow waves with membrane hyperpolarization. From the above results, it is suggested that ATP acts as an excitatory neurotransmitter, which mediates the rebound-contraction via P<SUB>2Y</SUB>-purinoceptor in guinea-pig gastric antrum.
