This study investigated the basic data of architectural design about framework dimensions inherent in a folk house of Yeosu city generally and systematically. We investigated the common dimensions of framework constitution for folk house (main building) seen a lot in Yeosu city. Most of the folk houses in Yeosu city were common people houses built from the end of 19th century to the 1960s and have maintained the same style for a long time. As a result of the study, common dimensions were calculated in two ways. One is Front toi/3ryang house and the other is Front/back toi/2kozu5ryang house. Front/back toi house was large in the case of full width, total height, and member thickness but, width of the front kan is no big difference. In other words, the scale of Front toi house and Front/back toi house is difference only in the rest except front kan (width). Among calculated common dimensions, the front kan of Front toi house and Front/back toi house in the plan, the kitchen is the widest, and the size is the same at 8.7 chucks degree. The next became small little by little in order of room 1(main room), room 2(center room), room 3(end room). As a result, the size of the room 3 of Front toi house reaches 7.7 chucks, and room 3 of Front/back toi house reaches 8.0 chucks. In the section dimensions, pillar height is in sum of floor height and pillar core height, Front toi house is 7.9 chucks, and Front/back toi house is 8.2 chucks. The investigation of basic data of architectural design is not only makes possible to grasp specific and simple to three-dimensional universal aspect on framework dimensions, but also documentation of folk house design know-how is done, and the architectural design standards of Korean folk house is written in the contents according to the area.

Volume change of the dredged soils is composed of the volume loss of soil particle flowing over an outflow weir with water and settlement due to both the self-weight consolidation in reclaimed layer and the desiccation at the surface of reclaimed layer. In order to estimate the amount of soil particles flowing over an outflow weir with water, the evaluation procedure of loss ratio of the dredged soils is proposed in the present study based on the Marsal's modified breakage theory and the results of hydrometer analyses. To verify a validity of the proposed procedure, evaluated loss ratio is compared with results from the other existing methods. The model test results and those of field test were compared and analyzed. Also, the variation of soil loss ratio was examined through the model test in the lab.

Suspended sediment budget in Gwangyang Bay was investigated using the data of suspended sediment concentration and vertical distribution of tidal currents at the mouth of the bay in the Yeosu Sound (Yeosu Haeman) . At the mouth of the bay suspended sediment concentration shows much higher value of approximately 17.80mg/l on the average near the bottom than the concentration near the surface where the average is 4.7mg/l. Tidal currents also show an asymmetry in magnitude between flood and ebb. Near the surface ebb is stronger than flood, while flood is stronger than ebb near the bottom. Due to the higher concentration and stronger flood current near the bottom, transport of suspended sediment near the bottom plays a major role to the sediment budget in the bay, and the bay is in net-depositional environment. The western part of the bay seems to gain the suspended sediment of approximately $5.66\times10^8g/day$, which corresponds to a sedimentation rate of about 1.15m/1,000years.

Heavy metals (Fe, Mn, Cr, Co, Cu, Ni, Zn, Pb) were determined in ninety-one surface sediments collected from Kwangyang Bay, south coast of Korea. The data show that the Fe, Cr, Ni, and Zn distribution in the bay can be described by metal vs. grain size relationship. However, the distribution pattern of Mn, Co, Cu and Pb were found to be changed because they are anthropogenically enriched to sediment. Correlation matrix and R-mode factor analyses revealed that two important factors controlling the distribution of metals in the bay are grain size and anthropogenic input.

This paper overall and systematically investigates of basic design know-how on commonly indwelling timber framework in a folk house in Yeosu area. in other words, Setting the goal of 'investigates of common form of timber framework', and for this goal, surveyed and analyzed for folk house a lot of findable in Yeosu area. As a result, elicits for four types plural common form((1) 4 front 'kan' - a hipped roof construction - front 'toi'/3 'ryang' - no central pillar/side beam type, (2) 4 front 'kan' - a hipped roof construction - front 'toi'/3 'ryang' - one side central pillar/central side beam type, (3) 4 front 'kan' - a hipped roof construction - front/back 'toi'/2'kozu'5'ryang' - no central pillar/side beam type, (4) 4 front 'kan' - a hipped roof construction - front/back 'toi'/'2kozu'5'ryang' - one side central pillar/central side beam type). Common form is at that time, so commonly located in the head of the technician that a form that play an exemplary role in design, or it is concretely assumed for commonly aimed form. in other words, Common form is come into existence on premise for basic design data. Documentation of folk house design know-how is done through this, and the base design and specification of korean private house is written in the contents divided into by areas.

The study of the modern age period folk house is still insufficient in the Korean folk house study. The study subject had a tendency towards mainly on the plan in the field of the traditional folk house which had been studied relatively lively. We were going to grasp the formation and the actual situation of the folk house in this paper targeting at Yeosu city where the folk houses were left relatively a lot. Specifically, we examined it how the composition and dimensions of timber framework changed according to period. The division of period from before 1910 to the 1960s classified it at 4 periods on the basis of the sociocultural change. However, as a result of investigation analysis, the change of the composition and dimensions of timber framework was classified at 3 periods not 4 periods. The division of 3 periods is "traditional era", "modern age 1", and "modern age 2" not "traditional era", "modern age", and "contemporary age". The folk house group came as a common name for folk house without doing the division of period until now. There is a meaning in that this paper subdivided the period of the folk house group by the change of the timber framework technology. The timber framework is the effective index to investigate the actual condition because the change is difficult after building. Therefore, we examined it including the dimensions as well as the composition of timber framework in this paper comprehensively and systematically.

Observation of land surface temperature in industrial areas is problematic, as it is not possible to construct a network of weather stations with sufficiently high density and continuous operation in such zones. Multiphase remote sensing data that cover a wide area and take a short time to process can enable the user to precisely and continuously measure the current and changing land surface temperatures in a certain region. Jeollanam-Do in South Korea is undergoing rapid industrialization, with the establishment of a number of industrial complexes, such as the Gwangyang Steelworks, Yeosu Industrial Complex, Yulchon Industrial complex, and Daebul Industrial Complex. To look into the properties of industrial complex's temperature, this study uses the thermal band of Landsat 7 ETM+ images acquired under thermal infrared wavelengths in order to calculate and compare the surface temperatures of the four above-named industrial complexes. From this, it is possible to obtain the basic information about industrial complex for environmental and natural resource management, which will aid industrial complex planners in developing methods of addressing environmental problems.

This paper outlines a plan to promote South Jeonnam region's logistics capability in connection with the regional logistics bases such as Gwangyang Port, Jangseong Integrated Freight Terminal, Mokpo Port and Muan International Airport. The capability of regional innovation bodies, and industrial innovation generally, needs to be improved by establishing a systematic regional innovation plan. Smaller import and export logistics bases, presently scattered in downtown Gwangju and its suburban area, need to be integrated as soon as possible, in advance of the completion of a traffic network connecting all of the triangle logistics bases. Moreover, plans to develop Muan International Airport to the status of a hub airport need to be established, and its function as an air freight terminal should be strengthened. Gwangyang Port and Mokpo Port should be developed as Korea's key harbors with international logistics bases the two ports, presently conducting simple cargo work, should be transformed into general logistics ports conducting logistics, assembling, trading, and international business by developing their surrounding areas.

Sonjook island is located Samsan-myeon, Yeosu-si, Jeollanam-do. All of field information was collected from January 2001 to November 2002. The vascular plants recorded as total 584 taxa, 5 forms, 60 varieties, 519 species, 365 geneta, 113 families. Sonjook islands shows the typical vegetations including the lower area of temperate region of Korean peninsula and evergreen broad-leaved forests, Pinus thunbergii forest. The Korean endemic plants were recorded as 13 taxa (5 variety, 8 species, 10 genera, 10 families), 4 taxa as rare and endangered plants (Psilotum nudum (L.) Griseb., Milletia japoniea A. Gray, Arisaema negishii Makino, Sarcanthus scolopendrifolius Makino). The naturalized plants were 23 taxa (20 genera, 9 families, 8.2％ among the total naturalized plants in Korea. This area is ecologically important place that Korea endemic plant, rare and endangered plants ranges much than area. On the one hand, threat from degraded by environmental pollution that share of naturalized plant rises gradually augment. Strong conservation policy and development control should be considered.
