  • This paper represents about the characteristics of wind turbine industry of the west-south seashore of Leading Industry Development for Honam Economic Region. These projects have 8 R&D and 3 non R&D project. The period of these projects is from October 2009 to April 2012. The R&D projects are composed three bright prospect products (1) the base construction of MW off-shore wind turbine components and system with Outer-rotor type PMSG, (2) the Development of 3MW wind power system with accommodation of the west-south seashore, and (3) the development of hybrid wind turbine system with wind base construction. Also, the non-R&D projects are composed three parts with above three bright prospect products. Above two projects support the companies with characteristic of low speed wind turbine system. Other project supports the companies related to wind turbine with small and medium capacity of form 3 kW to 10kW.

  • In this paper, the retardation capacity of marine clay and weathered soil of seashore waste landfill is analyzed by using a laboratory column apparatus for organic and inorganic components which can represent the components of the leachate of municipal waste landfill. The results show that sorption capacity marine clay for potassium is larger than that of weathered soil. Lead and cadmium are adsorbed completely at concentrations higher than the real concentrations developed in the landfill. The bottom soils of seashore landfill can also retard some nondegradable components of organics although their sorption capacities for organics were less than those for inorganics.

  • The objective of this study is to establish the algorithm for contamination criterion map based on the recent weather condition. Present criterion was established by the study on the countermeasure of salt contamination for electrical equipment. It did not represent recent weather condition. Therefore it is necessary to develop a contamination criterion map for assessment of contamination in design areas in Korea. To develop contamination criterion map of seashore areas, we used relational numerical formula based on past measurement data with the amount of rainfall, geomorphic variables(elevation slope, land use). These results are expected to be used as a reference material for design distribution facilities in seashore areas.

  • This study is aimed at suggesting ways to develop field trip or learning materials focusing on environment of Jeju seashore in order to make an effective field trip. To perform these purposes, the contents and concepts were analyzed from environment-related 'geological unit' of elementary science textbook. Afterwards, the places having the geological features in coincidence with them are chosen, and investigated, and these regions can develop into geological teaming places for field trip. Each teaming spot focuses on understanding and finding out the characteristic geological environment of rock shore, gravel shore, sand shore, shellfish shore, and tideland shore among Jeju shores. When field trip is conducted at the preparatory stage, students can get advance knowledge on geological concepts from textbook. The activity record paper is presented at the field trip stage where students observe geological phenomena on their own. After field trip is finished, the summary stage is given to solve some problems on the basis of the observed contents. The developed data from this research have its regional limits, but is surely useful for teachers who try to plan field trip when they especially choose the right field trip spots, or plan to make the process for field trip preparation of the environmental education. Furthermore, with this survey and activities, students can take the chance to improve the learning effect through their own experience on environment of Jeju seashore.

  • Dangsan forests had been established by local residents several hundred years ago. They were disturbed in various ways, but still remain in many villages where dangsan festivals are held every year. Although the remaining Dangsan forests represent korean rural cultural landscapes, their characteristics still remain to be uncovered. The objectives of this study were to understand the three elements, Dangsan tree (Divine tree), shrine and stone tower, and to investigate the culture at inland areas and seashore areas relation to Dangsan forests. Twenty cases of Dangsan forests at inland areas and twenty at seashore areas were investigated. There were nine shrines and six stone towers found out of twenty inland Dangsan forests. Fifteen shrines were found out of twenty seashore Dangsan forests. Stone tower was not found at seashore areas. Fifteen events of dangsan festival were investigated. Dangsan festival appeared to have played an important role to preserve Dangsan forests. Based on the findings of this study, Dangsan forests are, as landscape elements at inland and seashore areas, proved to have a potential for the improvement of cultural and natural landscapes in the country.

  • The survey was carried out over an area representing about 29% of the reclaimed paddy fields of west and south seashore in Korea. Scirpus maritimus L. was heavily infested all over the reclaimed paddy fields. But the weed was scarcely found in double cropping fields cultivating barley at paddy after rice or in reclaimed paddy fields where the cultivation was taken a long time.

  • One-hour average concentrations of ground-level ozone from around 80 monitoring stations in Korea during 1991 to 1993 were analyzed to examine characteristics of the ozone concentration variations. Two types of variations were observed: one was for the Capital area typified by Kwanghwmun, and the other was for the south and east seashore region typified by Tongkwangyang. In the Capital area including Seoul, Inchon, Kyonggi-do and Chunchon, mean daily 1-hout maximum was the highest in June following high monthly averages in spring. But frequent precipitation prevented further rise of daily maximum in July and August even though there were frequent episodes of high concentration exceeding 100ppb. In the south and east seashore region, average concentration was the highest throughout the year, and daily maximum and minimum simultaneously changed owing to small contributions from photochemical reactions. The typical annual variation was spring peak, summer down, and fall rise. Spring peak accompanied an usual observations of background variations at remote sites in the Northern Hemisphere. Riess of average and daily maximum with lower daily minimum in fall were attributable to photochemical reactions.

  • Recently, as quality river aggregates like sands and gravels become scarce, use of crushed stones and sands, seashore sands, and seashore gravels is increasing abruptly. And, aggregates recycled from slags and waste concretes are used. However, since the converter slag easily expands and breaks due to free lime, differently from the blast-furnace slag, it is not suitable for use as concrete aggregates. Since the atomized steel slag aggregate has slippery surface and spherical shape, the mortar flowing characteristics improved as the atomized steel slag content increases, without regard to the aggregates coarseness and water/cement ratio. The flow characteristics loss rate of the mortar manufactured from steel slag aggregates was similar to that of the mortar manufactured from washed sand only. The compact strength of the mortar manufactured from coarse PS Ball were larger than that manufactured from washing sand only.

  • When modern farm houses were built, they were made up of only residential parts. So that many new accessory building-private residential room, toilet, warehouse, storeroom, barn, cattle pen and etc.-were made without any order around modern farm houses. This study is aimed at grasping how the process and contents of extension of the accessory building of modern farm houses have been changed, understands and explicates the reason why accessory buildings of modern farm houses were changed and bring forward better directions about accessory building of modern farm houses at Samchok seashore area of Kangwon Province. The way for it which be made good that the scenery of a rural district was ruined by accessory buildings distributes and develops various standard models about accessory buildings that they are becoming to modern farm houses.
