This paper deals mainly with the genesis and classification of the Jeonnam series. These soils have brown to dark brown silt loam and silty clay loam A horizon(strong brown or reddish brown where eroded). Argillic B horizons are dominantly red or yellowish red silty clay loam to silty clay with moderately developed subangular blocky structure and with thin clay cutans on the ped faces. The C horizons are strongly and very deeply weathered strong brown, yellowish brown, pale brown and reddish yellow silty clay loam and sandy loam granitic saprolite. Content of clay increases with depth to a maximum between 100cm. Percolating water seems to be responsible for transportation and oriented deposition of clay. Chemically, soil reaction is strongly acid to medium acid throughout the profile. The content of organic matter is 1 to 2 percent, and decreases regularly with depth. Base saturation is low, based on amount of extractable cations. Characterisltically the Jeonnam series are similar to Red-Yellow Podzolic soils of the United States and are similar to Red-Yellow soils of the Japan. In the writer's opinion the Jeonnam soils are classified as Red Yellow soils. According to USDA 7th approximation, this soil can be classified as Typic Hapludults and in the FAO/UNESCO World Soil Map as Helvic Acrisols.

The effect of the hot water extract of defatted green tea seed cake (GTSE) on lipid metabolism and the underlying mechanisms of lipolysis in mature 3T3-L1 adipocytes were investigated. In this study, we found that the naringenin content of GTSE was 5.5 mg/g; however, catechins were not detected. The intracellular lipid droplets were stained with Oil Red O dye and quantified. Compared to the control, lipid accumulation was significantly decreased by 52%, and intracellular triglyceride (TG) level was reduced by 33% after treatment with GTSE at a concentration of $40{\mu}g/mL$. To determine the mechanism of reduction in TG content, we determined the level of fatty acid synthase (FAS), phosphorylation of adenosine monophosphate-activated protein kinase (AMPK), and acetyl-coenzyme A carboxylase (ACC) in the cell model. Incubation of the 3T3-L1 adipocytes with GTSE stimulated AMPK and ACC phosphorylation in a dose-dependent manner, and decreased the expression of FAS.

This study investigated the probiotic and functional characteristics of Mukeunji starter, Lactobacillus curvatus ML17, isolated from Mukeunji. Lb. curvatus ML17 was confirmed as a safe microorganism due to its non-hemolytic activity and non-production of harmful ${\beta}$-glucuronidase and ${\beta}$-glucosidase. Tolerance to artificial gastric and bile juice of Lb. curvatus ML17 was investigated. After incubation in artificial gastric and bile juice, the number of surviving cells was $1.38{\times}10^8$ CFU/mL. According to the results of adhesion assay, this strain also exhibited good adhesion to Caco-2 cells. Lb. curvatus ML17 showed good antimicrobial activity against food borne pathogens, especially Micrococcus luteus, Bacillus cereus, Salmonella enterica subsp. enterica, and Pseudomonas aeruginosa. Cell-free extract of Lb. curvatus ML17 exhibited high levels of DPPH scavenging capacity and inhibitory effects on growth of AGS human gastric adenocarcinoma cells and HT-29 human colon carcinoma cells. These results suggest that Lb. curvatus ML17 has potential for application in functional foods.

The ecological studies were conducted to identify some bark-beetles on apricot and plum trees in Jeonnam province. Harmful bark-beetles caught from apricot and plum trees were identified as Scolytus seulensis. Xyleborus atratus., X. germanus, X. rubricollis and X. saxeseni. The seoul barkbeetle emerged during the period from early May to late October $1980\~1981$, it happens twice in a year, with the peak July 10 and August 25 in 1950, July 15 and August 20 in 1981. A daily peak emerged for adults was at 11 AM to 1 PM. Distribution of holes on the apricot stems varied; more than 100 holes per meter in Henderson (Apricot) and Y-49057 (Apricot), 12 holes per meter in Derbyroyal (Apricot). Comparatively more holes were found in the European variety, and the cardinal distribution was in the order of east, south, west and north. The longer the longth of the mother-gallery, the greater number of egg-gallery found. Optimum temperature for mating was $27^{\circ}C$. The time for mating was longer during May-June than July-August. The fruit weight of damaged plum tree reached 12.25g around four weeks after flowering; where as that of normal tree increased up to 63.5g at harvest time. The natural enemy of the seoul bark beetle was Eurytoma sp. They were found as mature larva or pupa and they emerged from early May to the middle of June. Adult longevity was about a week.

Control thresholds for the management of beet army worm, Spodoptera exigua (Lepidoptera : Noctuidae) were evaluated on welsh onion of two different planting time. Two inoculation times were tested for each planting and the number of inoculated larva was 5, 10, 20, 40 per twenty plants. The injured rate of leaves was 33.5% to 10.9% at 7th September at 40 to 5 larva inoculation plot on the five days planting. That of leaves was 20.5% at 40 larva on the twenty days planting. The yields of welsh onion on non-inoculation plot were 4,395 kg per 10a. The rate of reduced yields was 49.2%(1,774.2 kg) and 36.5%(2,220.5 kg) at 40 larva inoculation on the 5 and 20 days planting, respectively. The linear relationships between population density and yield reduction were as following; it was Y=-43.474X + 3419.6 ($R^2\;=\;0.9698$) for 5 days and Y=-32.977X + 3518.9 ($R^2\;=\;0.9928$) for 20 days. Based on these results the control threshold level was estimated to be 1.8 larva for 5 days and 4.6 larva for 20 days per 20 plant. The more damaged leaves by S. exigua larva, the more yield reduction on welsh onion.

As a regional development gap between Southwest and Southeast of Jeonnam Province are becoming more serious, it is highly time to come up with measures for the balanced development of the two areas. This paper suggests construction of the Airport and Port Supporting Complex in apparent efforts to reduce the gap between the two areas and facilitate the Southwest economy. The Supporting Complex aims to constitute a triangle industrial cluster which is classified into the following three categories; 1. Traditional competitive industries 2. New growth engine industries 3. Attraction of companies u-turning from abroad such as China etc. To provide one-stop service through set-up of R&D Business Center is the heart of this triangle core. This paper had LQ and Shift&Share Analysis in an attempt to search for competitive industries among the traditional industries in Mokpo-si(city) and Muan-gun(county) of Jeonnam Province. As a result of the analysis, metal manufacturing industry and metal-working process products industry have been found competitive in the two areas. Among the new growth engine industries, this paper suggests precision instruments industry and advanced parts industry for utmost strengths of airport and port while u-turning industries from abroad include higher value-added textile industry and fashion industry. It is expected that all of above-mentioned industries for the triangle industrial cluster will contribute to laying the groundwork to develop regional economy further and create more jobs in the Southwest area of Jeonnam Province.

This investigation has been carried out for the purpose of the examination of current Gwangju and Jeonnam clinical pathology students' recognition of their departments and of effective employment guidance. Furthermore, it has examined the students' recognition on two sides; namely, their satisfaction with their own departments and their recognition of the employment of medical technologists. This investigation, with 389 students as its subjects from the clinical pathology departments at 4 universities in the Gwangju-Jeonnam Region, has compared and analyzed the data from the survey with a questionnaire from November 2008 to June 2009 by using the SPSS 12.0 package. Some of the remarkable results from the yielded data are as follows. As for the motivation for their application to the clinical pathology departments, the investigation of the students' satisfaction with their departments has revealed that 47.5% of the subjects indicated recommendation from friends or acquaintances while 22.1% reported that they had been informed of the departments through Internet. 70.4% of the subjects graduated from general high schools, 22.3% from commercial high schools, and 6.2% from technical high schools. Applicants from general high schools tend to decrease in number every year. 28.5% of the students judged professor's capability of lecture as an important part of their acquisition of licenses, and more than 65.6% of the subjects acknowledged the necessity of their self-study at night for the acquisition of license. As for the future prospect of the occupation of clinical technologist, 46.8% of the students replied that it was promising, while 39.1% reported that they had no ideas. From this we can confirm that the students of clinical pathology lacked a viewpoint of occupation and goals for future jobs. The investigation of the students'recognition of the employment of clinical technologists has revealed that 47.8% of them wanted to be employed in the Seoul-Gyeonggi Region due to the properties of their local universities, 29.0% of themlogpecteties of monesly salary to be 1,200,000~1,300,000 won, while 22.4% 1,300,000~1,400,000 won. These fiemres indicated that these students' salary ogpectations were relativplo lower than those from cities ertiprovinces. As for the greatest difficulty after employment, 31.1% of the subjects indicated the confliction among employees from variouatiolleges, 27.3% uncertainty of duties related to es of major, 24.9% bmrdens of self-development.

A field experiment was conducted to evaluate the effect of slow-release fertilizer on the yield and quality of the third-harvest tea leaves. The yield of the third harvested tea leaves was decreased to 5.8-14.4% in slow-release fertilizer block, except to the N $50kg\;10a^{-1}$ ($316kg\;10a^{-1}$), compared to traditional urea treatment ($313kg\;10a^{-1}$). Nitrogen uptake and nitrogen uptake efficiency of slow-release fertilizer was reduced as nitrogen application level increased. The contents of chemical components related to the tea quality such as total-nitrogen, total amino acid, chlorophyll and theanine were somewhat lower in the slow-release fertilizer treatments, except to the treatment of N $50kg\;10a^{-1}$, than those in the traditional urea application, but those of tannin, caffeine and vitamin C were not different among the treatments. In scoring test, apparence and quality of green tea of the slow-release fertility treatments were not different, except to the N $40kg\;10a^{-1}$ treatment, compared to those in the treatment of urea. In conclusion, slow-release fertilizer and conventional urea treatments showed not different in both yield and quality of green tea.
