고령토의 조직과 산출상태의 관찰결과 산화철 광물을 침전시킨 철의 주요 근원은 모암인 회장암에 함유된 각섬석과 녹니석이다. X선 회절 분석결과 침철석은 녹니석이 버미큘 라이트로 변질되고 각섬석이 용해되기 시작하는 하부 백색 광석에서 우세하며, 적철석은 각섬석, 녹니석 및 버미큘라이트가 심한 용탈작용을 받는 상부 적갈색 광석이나 열 개에서 침철석과 함께 산출된다. 침철석 및 적철석내 Fe에 대한 Al의 치환량은 각각 6~26 mol% 및 5~8mol%이며 이 두 값 사이에는 비례 관계가 있다. 회절선폭의 크기로부터 계산된 침철석과 적철석의 평균 입자크기는 340$\AA$ 이하이며 침철석은 약간의 침상을 보이는 반면 적철석은 탁상이다. 전자현미경 관찰에 의하면 버미큘라이트와 수반되는 침철석은 침상 또는 성상이나 적갈색 광석에서는 그러한 특징이 작다. 적철석은 육각 또는 원형을 보이나 상부 적갈색 광석에서는 보다 불？칙한 모양이다. 적철석과 침철석의 광물학적 특성을 합성실험에서 보고된 결과들과 비교하여 성인적 측면에서 논의되었다. 이 지역에서는 침철석과 적철석의 생성에 적합한 기후조건들이 중첩된 것으로 생각된다.

During a survey of fungal diversity in Korea, two fungal strains, KNU17-1 and KNU17-199, were isolated from paddy field soil in Yangpyeong and Sancheong, respectively, in Korea. These fungal isolates were analyzed based on their morphological characteristics and the molecular phylogenetic analysis of the internal transcribed spacer (ITS) rDNA sequences. On the basis of their morphology and phylogeny, KNU17-1 and KNU17-199 isolates were identified as Albifimbria verrucaria and Deconica coprophila, respectively. To the best of our knowledge, A. verrucaria and D. coprophila have not yet been reported in Korea. Thus, this is the first report of these species in Korea.

This study estimated the effect of sowing and harvesting dates on dry matter (DM) yield and feed value of forage oats at Sancheong, Korea. The forage oats (Darkhorse vs. Highspeed) were used in this experiment. The experimental main plots consisted of the different sowing and harvesting dates at 2 seasons as follows: spring oats of sowing (February 25, March 3 and March 13) and harvesting (May 27, June 6 and June 16); and fall oats of sowing (August 15, August 25 and September 4) and harvesting (October 15, October 25 and November 4). On spring oats, Highspeed sown on March 3 and then harvesting on June 6 had the highest (p<0.05) plant length and DM yield. Crude protein content decreased (p<0.05) in seed of the delayed-harvesting Highspeed. On fall oats, plant length and DM yield with the delayed-harvesting date increased (p<0.05), while crude protein content of the delayed-harvesting Highspeed decreased (p<0.05). This study concluded that the spring oat sown in early March and then harvesting in early June was recommended to increase dry matter and feed value although the fall oat sown in end August and then harvesting in early November was recommended for fall period.

This study examined figurative characters of rice terraces, and is intended to seek figurative possibility of a natural scene by selecting Gyeongnam Area Namhae Gacheon rice terraces, Sancheong Imcheon rice terraces and Hamyang Macheon rice terraces through an analysis of the target land. As a theoretical background, studies of a natural scene and figuration-related literature were looked into, and for figuring a natural scene on the basis of the results, the character of the topography of rice terraces was divided into 9 items as follows by generalizing the inspiration obtained from the natural scenic character and spatial character of rice terraces represented from the topography: (1) Inclination showing the degree of the slope of rice terraces, (2) The bending showed by unevenness of the edge line of rice terraces, (3) The degree of parallelism of the up-and-down edge line, (4) The size of the width of the section of each rice terrace, (5) The area of the total rice terraces, (6) Step gap that indicates the difference of high and low of the up-and-down small rice terraces, (7) Figuration as an image represented by the external form of the total rice terraces, (8) Naturalness and artificiality kept by the total scene, (9) Softness of cornerstones or soil that forms small rice terraces, an atmosphere produced by the total scenes, etc. The results of analysis made through GIS, with rice terraces of Gyeongnam Namhae, Sancheong and Hamyang Area as the target land, are as follows. First, the steeper the inclination is, the higher the step difference of cornerstones becomes, and the steeper the inclination, the narrower the area and width become, so that it could be known that, in rice terraces, inclination is proportional to step difference and the area is inversely proportional to the width. Second, it is considered that line showed in rice terraces, area elements and reiteration, repeated changes, and changes in the scene affected by the surrounding environment including those according to season can be converted into a variety of images according to an individual disposition. Third, it was decided that it is possible to figure repetitive composition and directivity, motility, order and change, etc. into a common type drawn from each target land. This paper, as a study of basic materials for expressing figuration in an environment field, investigated and analyzed the surrounding environment of the target land, and is significant in that it attempted the possibility of being able to generalize the environmental beauty of the target land as one figurative element. More precise studies are expected to be made later.

The physicochemical quality characteristics of the domestic and imported commercial dried persimmons were investigated. The moisture content of dried persimmon was approximately 22.78~61.64%, while the moisture contents of the Chinese dried persimmon were 22.78 and 28.20%, respectively, and were lower than the domestic dried persimmon. The pH of the Chinese dried persimmon was 5.09~5.99, while the pH of the Haman dried persimmon has the highest value (pH 5.99). The Brix was approximately $25.07{\sim}42.93^{\circ}Brix$ and weight of dried persimmons were 29.77~77.95 g, while the weight of Yeongdong dried persimmon has the lowest (29.77 g), and the weight of the Sancheong dried persimmon has the highest value. The L values were 18.27~66.20. The a values were -1.26~10.70 and a value of the Sancheong dried persimmon was 10.70, which was the highest. The b values were 2.81~25.25, wherein the b value of the Cheongdo semi-dried persimmon and Sancheong dried persimmon were25.25 and 21.98, respectively, and were higher than others. The appearance score of the sensory characteristics were the highest in Cheongdo semi-dried persimmon, while the appearance score of Wanju black persimmon was 1.39, which was the lowest. The overall acceptability of the Chinese dred persimmons (No.2) was the highest, while that of the Yeongdong, Hadong and Sangju dried persimmons have higher values than the other dried persimmons. The sulfur dioxide content of the 9 kinds of commercial dried persimmon was lower than 10 mg/kg, but not detected.

This experiment was conducted at Sancheong from 2013 to 2015. The objective of this study was to establish the seeding rate, and to clarify the optimum nitrogen fertilizer level for rye seed production in the southern area of Korea. We employed Korean rye cultivar 'Gogu' in this test. The experimental design was a split-plot design with three replications. A split-plot design was used with three seeding levels (3, 5, and 7 kg 10 a^-1) on the main plots and other treatments fully randomized in sub-plots. A factorial arrangement of treatments included three different nitrogen fertilizer levels (0, 3, 6, and 9 kg 10 a^-1). The grain yields of rye affected by increasing the seeding rate. The number of spike per m² and immature grain weight was increasing, while the fertility rate and the number of grain per spike were decreased as seeding rate were increased from 3 kg 10 a^-1 to 7 kg 10 a^-1. The percentage of a productive tiller, 1-liter weight, and 1000-grain weight also decrease by increasing seeding but the grain yields of rye had less effect. There was an increase in the number of spike per m², the number of grain per spike, and grain yields as nitrogen fertilizer level was increased from 0 kg 10 a^-1 to 9 kg 10 a^-1 and followed a delaying heading and an increasing lodging of the plant. But grain yields did not affected by the interaction of seeding rate × nitrogen fertilizer levels. The best seeding rate and nitrogen fertilizer level for rye seed production were 5 kg and 3 kg 10 a^-1, respectively, considering seed and fertilizer reduction and the prevention of pollution by excess fertilization.

The genetic diversity and structure of eight populations of Coreanomecon hylomeconoides Nakai, an endemic Korean plant, were investigated using 50 ISSR loci from eight primers. The average percentage of polymorphic loci was 47.3%. The Shannon's index (SI=0.218) and gene diversity (h=0.142) were relatively lower than those of other long-lived perennials. The Sancheong (SI=0.233, h=0153), Gwangyang (SI=0.263, h=0.171), and Suncheon (SI=0.241, h=0.159) populations showed greater genetic diversity than the Namhae and Gwangju populations, which are on the edge of the distribution. Analysis of molecular variance (AMOVA) showed that 18% of the total variation could be attributed to differences among populations, and 82% to differences within populations, indicating moderate gene flow among adjacent populations. These results were supported by value of Nm (2.184). The UPGMA conducted using the genetic distance and Bayesian cluster analysis showed a remarkable geographic trend structured into east and west regions. Overall, the results indicate that the Sancheong and Gwangyang populations, which had a large population size and higher degree of genetic diversity, should be the focus of in situ conservation.

The Charnockite in Sancheong region is quarzofeldspathic rock containing orthopyroxene and garnet with a color dark than common granitic rocks. The Chamockite are mostly massive and medium to coarse-grained with K-feldspar phenocryst, but reveal weak foliation. The rock consist mainly of quartz, K-feldspar, plagioclase and orhopyroxene, with biotite, garnet, and anthophyllite. In petrochemistry, the Chamockite has 61-65% $SiO_2$ contents, varying gradually into the margin contacted with orthogneiss, which have compositions of felsic igneous rocks. Major element show almost systematical variation with those of the marginal orthogneisses, except the hornblende gneiss and anorthosite. The Charnockite and orthogneisses show the tholeiitic differentiational trend. Trace and rare earth element abundance patterns in the Charnockite show remarkable negative Sr and Eu anomalies similar to orthogneisses, but different from the hornblende gneiss and anorthosite. Eu contents of the Charnockite are richer than that of orthogneisses. The metamorphic condition of the Charnockite were tested by an orthopyroxene-garnet geotherrnorneter and a plagioclase-garnet geobarometer. Estimated P-T conditions are about $761^{\circ}C$ and 7 kbar at peak metamorphism, but $653^{\circ}C$ and 6.4 kbar at retrograde metamorphism. This suggests that the Charnockite have from an early stage of high-grade metamorphism to represent the granulite facies and then to a late stage medium-grade metamorphism belonging to the amphibolite facies.

This study was carried out to develop local allometric biomass regression equations and to estimate aboveground biomass of red pine (Pinus densiflora S. et Z.) stands among three regions (Hadong, Hamyang, Sancheong) from the western regions of Gyeongnam province. We selected three natural red pine stands with similar stand ages (about 40-year-old) from each region. The allometric regression equations were significant in all tree components (P<0.05) and the determination of coefficient ($R^2$) ranged 0.87 from 0.99. There was a significant difference (P<0.05) in the biomass of tree components among three regions. The biomass was 173.3 Mg/ha in Hadong, 131.0 Mg/ha in Sancheong, and 66.5 Mg/ha in Hamyang. The proportion of biomass was 70.4-77.1% in stemwood, 10.9-15.2% in branch, 8.9-10.4% in stembark, and 3.1-4.4% in needle. The results indicated that red pine stands in the western Gyeongnam regions showed the significant difference of aboveground biomass which was attributed to site quality and stand density.

Resistance to chestnut gall wasp (Dryocosmus kuriphilus) of Korean prevailing chestnut cultivars, new cultivars released by Korea Forest Research Institute (KFRI), and local cultivars by growers was investigated to select optimal cultivars suitable for main chestnut producing areas. During three years investigated from 2004 to 2006, we could find no damage by chestnut gall wasp in any cultivars of test sites located in Gongju and Chungju of the central area. However, most cultivars of Gwangyang, Sancheong and Hapcheon sites located in the southern area showed a lot of damage by chestnut gall wasp. Hapcheon was most severe in comparison with regional damage by chestnut gall wasp. From comparison among cultivars, Kwangeun, Sandae, Eunsan and Idae released by KFRI showed no damage suggesting the highest resistant cultivars. On the contrary, over 20% in total damage by chestnut gall wasp was investigated in Tanzawa, Riheiguri, Kurakata-amaguri, Pyeonggi, Gwangdeok, Seil, Sinipyeong and Yumabyuni suggesting susceptible cultivars. In damage by chestnut gall wasp according to investigated position within tree, weak shoot was more severe than bearing shoot. Damage by chestnut gall wasp of major cultivars in Gwangyang, Sancheong and Hapcheon sites was remarkably decreased in 2006, and it seems to be caused by biological control by natural enemies such as Torymus sinensis.
