  • The process of constructing coastal digital elevation model(DEM), for the 3 dimensional analysis, is composed by abstracting land layers for land elevation and water depth, reprojecting UTM, relocating geographical grid, and interpolating works. The geomorphic set of shallow sea, including tidal current, tidal zone deposition, and water depth distribution, was analyzed by eye search of Landsat TM image, masking of land zone, band combination and regression analysis. Some horizontal differences, between combined DEM and surveyed data of shallow sea, was corrected for analysis. Analyzed geomorphic elements are stream channel, alluvial fan, coastal terrace, tidal current. and shallow sea bank. Results of analysis present that transported fluvial materials influence tidal sedimentation, especially from Gahwacheon river, for the role of artificial draining flooding waters from Jinyang Reservoir, almost in the summer season. In the coastal area with less tidal current, more fine materials are deposited. The influence of currental deposition are higher on small pockets with west coast of well developed terraces. The lower skirt of alluvial fans developed into the tidal zone of shallow sea. Small pocket type bays are closed by coastal current, and less influenced from tidal deposition. The bank of Jinju Bay are developed originally from submerging of remnant erosional mountain ranges, and play on the role of trapping fine materials.

  • Distribution of population densities of heterotrophic bacteria, E. coli, and Salmonella and Shigella in seawater and sediments at 40 stations near Samcheonpo Bay were measured for 3 times from July to December, 2003. Population densities of heterotrophic bacteria in seawater during survey periods were in the range of $1.7{\pm}0.9{\times}10^3{\sim}2.4{\pm}0.9{\times}10^5$ CFU $mL^{-1}$ and the highest density was shown at St. 34 during the sampling period of September, 2003. Population densities of heterotrophic bacteria were shown higher values on September than those of July and December at all sampling stations. Population densities of anaerobic heterotrophic bacteria in sediments during survey periods were in the range of $2.2{\pm}0.2{\times}10^3{\sim}2.0{\pm}0.2{\times}10^5$ CFU $mL^{-1}$ and their population densities at sampling stations far from Samcheonpo Bay measured lower values than those near Samcheonpo Bay. Population densities of anaerobic heterotrophic bacteria in the sediments were not affected by physico-chemical factors of upper water environment. E. coli were detected only at 8 stations in seawater and 4 stations in the sediments among 40 sampling stations on July and were not detected during September and December. Salmonella and Shigella were detected only a few stations on July and September during sampling periods.

  • Physicochemical characteristics of traditional kochujang fermented for 6 months and commercial kochujang were compared. Tested kochujang included 18 kinds of Sunchang kochujang prepared with glutinous rice, 10 kinds of Boeun kochujang prepared with barley and 17 kinds of Sachun kochujang prepared with wheat, and 10 kinds of commercial kochujang. Major free sugar was found to be glucose both in traditional and commercial kochujang. Fructose, maltose, and sucrose were also detected in small amounts. The contents of free sugars in traditional kochujang was approximately one fourth of those presented in commercial kochujang. Commercial kochujang showed the highest level of total free amino acids followed in decreasing order by Sachun, Sunchang, and Boeun kochujang. The most abundant free amino acid was serine in Sunchang kochujang and aspartic acid both in Boeun and Sachun kochujang. On the other hand, glutamic acid was the most abundant amino acid in commercial kochujang. Volatile organic acids in various kochujang were determined and acetic, propionic, butyric, and 3-methyl butanoic acids were found in traditional kochujang. However, 3-methyl butanoic arid was not found in commercial kochujang. The most abundant volatile acid was acetic acid in both tradtional and commercial kochujang. Analysis of non-volatile organic acids showed that large amounts of lactic, oxalic, and succinic acids were found in traditional and commercial kochujang. In addition to these, small amounts of itaconic, malic, malonic, and pyroglutamic acids were found in commercial kochujang.

  • The Grave encapsulated by lime soil mixture were excavated with clothing and hemp shoes from the Choseon Dynasty in Gooam, Sacheon. Hemp shoes have wood in the center and their surroundings were made of complex materials including herbaceous ones but the front part was lost or became very fragile. We analyzed the hemp shoes and pre-test of consolidant for conservation treatment of hemp shoes. As a result of analyzing, three kinds of plants were identified. For hemp shoes, Oryza spp, hemp, and one kind of dicotyledones were used and it was analyzed that fabrics attached to the back of Dogaengi was cotton. Conservation methods for pre-test of consolidant, Polyethylene Glycol, Paraloid-B72, Dammar gum, Methyl Cellulose and Silicone resin was selected. The solution was sprayed twice in a 24-hour duration. Properties of consolidant was measured; color difference, glossiness difference, folding streangth and tensile streangth. By comparing the results, PEG was confirmed to the most suitable as consolidant. For the conservation treatment, cleaning and strengthening was conducted. For strengthening treatment, PEG 4000 was selected given that the shoes were made of complex materials. The PEG impregnation method was applied with the PEG 4000 concentration gradually changing from 5% to 80% for reinforcement. Then humidity- controlled drying in order to avoid any rapid environment change.

  • Occurrence of scarabs at sweet persimmon (Diospyros kaki var. Fuyu) orchards was investigated by mercury light traps every one week interval in several areas in Gyeongnam province including, Jinju, Sacheon, Sancheong, and Gimhae, from April to September in 2000 and 2001. In addition, damage of persimmon by scarabs was observed every ten days interval at three orchards in Jinju and at one in Gimhae from late May to late October. Although sixteen species of 12 genera were attracted to the traps, species and number of catches were different according to orchards and years. Holotrichia morosa was most dominant in Jinju, Sacheon, and Sancheong. Total number of scarabs attracted to the traps was highest at the orchard surrounded by chestnut orchards in Sancheong. Fruits of sweet persimmon were not damaged by scarabs at the studied orchards. However, leaves and calyxes were slightly damaged by Adoretus tenuimaculatus. Maximum average numbers of the damaged leaves and calyxes throughout the year by A. tenuimaculatus were 0.33 leaves from 10 new shoots and 0.07 calyxes from 15 fruits. Gametis jucunda and Popillia mutans damaged flowers and calyxes. Maximum average numbers of damaged flowers and calyxes by these 2 species were the same as 0.03 from 15 flowers and 15 calyxes, respectively. These levels of damage suggest that the scarabs are not economically injurious to sweet persimmon fruits in Korea.

  • The sedimentary sequence of the non-marine Cretaceous Jinju Formation from Sacheon, Korea, contains a number of rod-shaped stromatolites (RSS) characterized by concentric lamination with curd-shaped, stratiform, and small columnar stromatolites. Unlike the world trend, a massive distribution of rod-shaped stomatolite was discovered in the region. The mineral composition, diagenetic alteration, and weathering process of the kind were analyzed by EPMA. The gross morphology of RSS is almost identical to broken plant twigs or stems formed by microbial activity onto which it grew. RSSs are interpreted as stromatolitic algae over plant twigs, which formed through concentric carbonate precipitation by epiphytic algal photosynthesis. The distribution of localities and horizons of the stromatolite imply that RSS is allochthonous and autochthonous. Two types of cyanobacterial filaments and one type of peen algal filament were discovered. The size frequency distribution of calcified filamentous microfossils found in stromatolite was $2.2{\mu}m\;and\;7.8{\mu}m$ in mean diameter of the former, $32.3{\mu}m$ in mean diameter of the latter. The cyanobacterial fossils played a key role in the formation of stromatolite, while the green algal filament was auxiliary stromatolite-builder stromatolites. The filamentous microfossils including trichome were found within the stromatolitic laminae.

  • Quality characteristics of 3 kinds of traditional kochujang were investigated during 6 months of fermentation in order to obtain information for the industrial production of traditional kochujarg. Tested kochujang included Sunchang kochujang prepared with glutinous rice, Boeun kochujang prepared with barley, and Sachun kochujang prepared with wheat. The reducing sugar contents of Sunchang, Boeun, and Sachun kochujang increased up to 30, 90, and 150 days of fermentation, respectively, and then decreased thereafter. Ethanol contents of traditional kochujang increased up to $0.4{\sim}1.2%\;at\;120{\sim}150$ days of fermentation and decreased thereafter. Amino nitrogen content of Sunchang kochujang showed a slight increase during fermentation, however, those of Boeun and Sachun kochujang showed a rapid increase up to 150 days of fermentation. Ammoniacal nitrogen content of 100 g kochujang increased up to $50{\sim}75mg$ at 60 days of fermentation and leveled off thereafter. Capsaicin and capsanthin contents of 100 g kochujang were $15{\sim}18mg\;and\;60{\sim}180mg$ before fermentation and decreased to $12{\sim}14mg$ and $50{\sim}120mg$ at 180 days of fermentation, respectively.

  • This study was carried out to identify the ecological characters easily changeable with the conditions of temperature and day-length and to ascertain the managable means which can optimize the barley plants to secure the maximae yield and early heading under controlled condition. Yield and yield components were greatly varied with temperature. Especially, effective tiller formation and grain filling of sub-tillers were more favorably affected by thermal treatment than those of main tiller. In thermic response, 'Kangbori' was less susceptible than others, while 'Sacheon #6' showed particular susceptability. The varietal differences of photoperiodic response were recognized on all investigated traits and their degree of response were similar to those with temperature. Among varieties, 'Kangbori' was comparably sensitive on several characters while 'Sacheon #6' displaying low light-sensitivity. The turning point at which heading might be radically stimulated was estimated as about 10.5 hour day-length in 3 tested varieties and above 18 hours of irradiance was considered ineffective for more rapid heading. The condition under which barley varieties may obtain maximal yield and resonably early heading was 15$^{\circ}C$ in temperature and 12 to 15 hours of day-length, regardless of varieties. of day-length, regardless of varieties.

  • The purpose of this paper is to study the characteristics and vertical development of the sea breeze over Sacheon area which is located at Sacheon Bay, southern coastal area of Korean Peninsula. Also, the characteristics of the sea breeze over Sacheon area are compared with those over Kimhae and Pusan area. The results were as follows: the occurrence frequencies, 98.1 days for a year of the study area, are higher than those of Kimhae (56.8 days) and Pusan area (65.8 days). March shows the highest occurrence frequency (12.3%), and July shows the lowest (3.3%). The mean onset time of the sea-breeze over Sacheon area (13:24) is, except for summer season, earlier than that over Kimhae area (13:54) and the mean subsided time of the sea-breeze over Sacheon area (19:18) is earlier than that over Kimhae area (20:18). The mean duration (5.9 hrs.) of sea-breeze is, except for winter season, shorter than that over Kimhae area (6.5 hrs.). The mean speed of the sea-breeze over Sacheon area (5.8 kts) is, except for winter season, lower than that over Kimhae area (6.8kts). April shows the maximum speed (7.7kts), and December shows the minimum (4.8kts). When the sea-breeze has occurred, the depth of the sea-breeze grows higher and higher, and when subsided, it becomes lower and lower, and sometimes after is passed 21:00 (L. S. T.) there exists the sea-breeze above 1000 feet in altitude.

  • The stone lantern of the four guardian kings in the Beopjusa temple at Boeun was mainly made of biotite granodiorite consisting of porphyritic-textured potassium feldspar and included in ilmenite series. A base stone made of alkali granite was buried, after founded its place during an earlier restoration process. Cracking and break out are noticeable on this object. In addition, discoloration, salt crusting, and epiphytes were observed. The lantern was vulnerable in terms of physical and structural stability caused by cracking in the front and back of the light chamber and in the non-horizontal direction. According to the conservational condition of the stone lantern, structural reinforcement was carried out based on calculations, including those on the position, size, and anchor length of the titanium stiffener. Chemical and biological pollutants were washed off without damage to the surface of the stone material. Oxygenated iron pieces were replaced with titanium. Ethyl silicate was applied to the surface of the lantern for consolidation and smooth drainage.
