Porcine transmissible gastroenteritis virus (TGEV), porcine epidemic diarrhea virus (PEDV) and rotaviruses are considered as the most important causative agents of diarrhea in piglets. The study established 3 method vaccination programs to prevent PEDV. A (LL)group inoculated twice vaccinations on 2-weeks-interval during the late term of pregnant sows with PEDV live vaccine. The B (LKK) group was applied that one time single PEDV live vaccine at the pre-mate followed by the TGEV PEDV combined inactivated vaccine (twice vaccination on 2-weeks interval at the third-trimester). C (KK) group was applied to sow which inoculated twice vaccination on 2-weeks-interval during the late term of pregnant sows with by the TGEV, PEDV combined inactivated vaccine. As the result of SN test on sows in the pig farm before vaccination, antibody titers was showed 9/45 (20.0%). By comparison with the serum neutralizing antibody titers against PEDV of the vaccination programs after PEDV of the vaccination, A group and B group vaccination method was higher than those of C group in sows. In the piglets up to 2 weeks of age, A group was showed antibody titers of 17/22 (81.8%) that showed 2-128, and B group was showed antibody titers of 30/37 (81.1%) that showed 2-512, and C group was showed antibody titers of 14/28 (50.0%) that showed 2-32. On the other hand, PEDV antibody titers were tested for the survey. As the results of SN test, Aujeszky's disease survey in 54 pig farms from november 2005 to august 2006, antibody titers of 47/286 (16.4%) showed above 2. Five breeding farms were antibody titers of 38/77 (49.4%), Wanggung zone farms antibody titers of 59/85 (69.4%). In pigs farms vaccinated the first of twice PEDV live vaccine, and after 6 month, the second of twice TGEV PEDV combined inactivated vaccine (LLKK, 256-1024 titer) method was higher than those of vaccinated twice the early term of pregnant, and twice the late term of pregnant sows of PEDV live vaccine (LLLL, 32 titer).

The Yocheon is an upper stream of Sumjin river, passing through Namwon city. The water temperature of the stream increases from upper stream to downstream. The amount of COD, T-P, T-N, EC, TDS abruptly increases at measuring site 8. Whereas, the pH and DO level abruptly decreases at this site. At this point, the Yocheon river joins another small stream passing through the central part of Namwon city. At a further downstream pass site 8, the amount of COD on April and June (a dry season) is on third grade of water quality for lacustrine. This contamination suggests that sewage from the Namwon city provide COD, T-N, T-P into the stream. At point 2, the high amount of T-N indicates that the upper stream is contaminated by agricultural activity.

Background: We investigated the antioxidant, anti-wrinkles, whitening, and moisturizing properties and amounts of phenolic compounds of ethanol extracts from flowers of 10 resource plants from Namwon and Mt. Jiri., Korea. Methods and Results: We measured antioxidant efficacy based on the total polyphenol, and total flavonoid content, and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. We evaluated the inhibitory effect on melanin synthesis and tyrosinase activity for the whitening effect. Furthermore, we analyzed the elastase and matrix metalloproteinase-1 (MMP-1) inhibition activity for anti-wrinkle capacity. To evaluate the moisturizing effect, we examined hyaluronan synthase (HAS) mRNA expression. In addition, the 19 phenolic compounds were detected using high performace liquid chromatography (HPLC). Among the 10 flowers, the antioxidant effect was high in the order of Rosa multiflora, Nelumbo nucifera, and Elsholtzia splendens. Whitening effect was high in the order of N. nucifera, R. multiflora, and Dendranthema zawadskii. As for the anti-wrinkle property, N. nucifera was the most effective followed by R. multiflora. Taraxacum coreanum was the best for moisturizing effect, followed by D. zawadskii, and E. splendens. Seven phenolic compounds were detected in the extracts of the 10 flowers. Conclusions: Overall, the extracts of five flowers extracts showed strong potential as antioxidant, whitening, anti-wrinkle, and moisturizing functional cosmetic agents.

We report adventages of employing MgO as a differentiation index for the Namwon granitic complex. It is shown to be much more sensitive than the usual Harker index. The complex can be divided into two groups on the basis of $TiO_2$/MgO ratio. The low $TiO_2$/MgO group consists of hornblende biotite tonalite-granodiorite, porphyritic hornblende biotite granodiorite (PHBGd) and part of biotite granite (loBG). PHBGd shows its own distinct variation in the low group. This group is characterized in most cases by the presence of hornblende, even if it occurs as a trace amount. The high $TiO_2$/MgO group consists of part of biotite granite (hiBG) and two mica granite. The major element differences between rock types are also apparent in biotite chemistry. These chemical data indicate that at least two distinct origins of magma are rquired for the complex. Two kinds of biotite granite revealed in this study show distinct geographic distribution, suggesting that a new geologic map should be made.

Incidence of stem rot on carnation (Dianthus caryophyllus L.) ranged 11 to 29% in Namwon and Chongup area during the growing seasons from 1993 to 1994. Among 129 isolates from carnations in Namwon, 77 isolates were identified as Rhizoctonia solani, 38 isolates were Fusarium oxysporum and 14 isolates were not identified. Among 169 isolates in Chongup, 19 isolates were identified as R. solani, 106 isolates as F. oxysporum and 44 isolates were not identified. Among 77 isolates of R. solani isolated from the specimens of Namwon, 52 isolates were classified as anastomosis group AG 2-2 by anastomosis test, 14 isolates as AG 2-1 and 11 isolates as AG 4. Among 19 isolates from specimens of Chongup, 14 isolates were classified as anastomosis group AG 2-2 and 5 isolates as AG 4. Pathogenicity tests revealed that isolates of F. oxysporum and R.solani AG 2-2 were highly virulent and isolates of R.solani AG 2-1 and AG 4 were mildly virulent.

The Namwon and Sunchang granites are neighbouring plutons intruding the Yeongnam massif and the Okcheon metamorphic belt, respectively in the southwestern part of the Korean peninsula. In this study, SHRIMP zircon U-Pb ages are determined from these plutons. The results show that the emplacement age of the Namwon granite is $185.8{\pm}0.9(2{\sigma})$ Ma. We obtained $175.0{\pm}2.0(2{\sigma})$ Ma from the northern part and $179.8{\pm}0.9(2{\sigma})$ Ma from the central part of the Sunchang granite, yielding $177.4{\pm}1.3(2{\sigma})$ Ma as the average age of the pluton. Such age results confirm that the Honam shear zone, which cause marked deformation of the Sunchang granite, was active after ca. 175 Ma.

The tomb is an important clue for understanding the ancient society of Namwon (南原). In order to establish local identity through the burial mounds and appropriately preserve and utilize it, basic investigation should be conducted to grasp the current situation of the burials. Additionally, excavation surveys and research are needed to understand the nature of the tombs. Based on this activity, local people should be informed about the importance of the tombs and participate in the preservation and utilization activities together. Preservation and utilization should be of the complex type. However, it should be improved systematically based on the fact that the tombs have not been properly investigated. In order to do this, the related organizations and budgets should be allocated at all times in Namwon City.

The nitrogen contents of some forms in Burley tobacco leaf cultivated in Yaesan, Mokpo and Namwon district were investigated. The rate of each form in total nitrogen contents were as follows ; Protein form nitrogen 30~33 % Nitrate form nitrogen 10~123% Alkaloid form nitrogen 8~16 % Ammonia form nitrogen 6~9% Amide form nitrogen 2~ 3% Other form nitrogen 26~44 % The order of nitrate form nitrogen content on the nitrogen of each tobacco cultivated in three area was Yaesan > Namwon > Mokpo, but that of alkaloid form nitrogen was reverse order of nitrate form nitrogen. As for Quality ( grade ), the orders of alkaloid and ammonia form nitrogen content on total nitrogen were H5> 3> 1> L 1> 3> 5, but that of nitrate form nitrogen was reversed.

Groundwater chemistry in Namwon area, Korea, was investigated to understand the contribution of geochemical processes on groundwater chemistry. For this study, a total of 279 groundwater samples were collected from 93 wells distributed over the study area. Higher concentrations of major ions are generally encountered in the shallow alluvial wells, suggesting that these chemicals are originated from the surface contamination sources. Mass balance analysis based on reaction stoichiometry reveals that the water chemistry is regulated by three major chemical processes: weathering of silicate/ carbonate minerals, input of C1/SO$_4$ salts, and nitrate generating processes. The results show that mineral weathering is the most dominating factor regulating the groundwater chemistry. However, the groundwaters with the higher salt concentration indicate the larger mineral weathering effect, suggesting that some part of the mineral weathering effect is also associated with the anthropogenic activities such as limes applied to the cultivated lands, carbonates (CaCO$_3$) in the cement materials.

We investigated the serological prevalence of avian metapneumovirus (AMPV), avian reovirus (ARV), Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) in 760 broiler breeder (38 flocks), in the Jeonbuk province in 2013. This study was conducted to evaluate the immune and infection status of the broiler breeder flocks against AMPV, ARV, MG, MS by an enzyme-linked immunosorbent assay (ELISA). Serological test for AMPV were positive 37 (97.3%) flocks and 712 (93.6%) broiler breeder and geometric mean antibody titers were $16,350{\pm}10,195$, ARV were high positive rate 100% (38/38) flocks and 97.8% (743/760). The seropositive flocks against MG were 71.1% (27/38) and the geometric mean antibody titers were $2,474{\pm}2,045$, whereas the rates of positive flocks against MS were 50.0% (19/38) and the geometric mean antibody titers were $1,469{\pm}1,230$.
