This study aims to find out the change trend of the existing vacant houses in the small and medium sized farming city. And the using method of those houses is proposed in this paper. Especially to find out the change trend ratio of vacant houses in the case, the historic conservation area - Keumma village is selected as the research target area. To carry out this study, it was surveyed in 2013 when they were not designated as the special area first. And it is reviewed in 2017 when it is designated. The contents of the survey were their use, old age, structure, materials, color, roof of the main building and wall. they were surveyed by direct and interview survey. And thew were analyzed and synthesized. It is concluded that the 142 vacant houses in 2013 were declined 46houses in 2017. It is caused by the government support. And they will be declined continuously. The architectural statues of vacant houses between in 2013 and in 2017 are almost same in it's use, old age, structure, materials, color, roof of the main building and wall. In the use ratio of the vacant houses that of residence is most high, and that of warehouses, commerce are followed in turn. The reason of that statues is moving out is the first and the death of house holder, the difficulty of managing are followed. As the their re-use plan of owners, the selling is the first, constructing new buildings and the renovation them are followed. As the method of their use, re-use, community facilities, managing in the vacant houses bank are proposed. As the vacant houses are the reason of bad elements in the rural landscape in the farm village, the method of its improvement will be carried out.

Input-output(I-O) analysis is now widely used to examine the economic impact of tourism. The study aims to demonstrate the impact of agri-tourism development project on local development in terms of income and employment. Based on the I-O transactions tables developed by Bank of Korea (2011), rural tourism related sectoral multipliers were derived with respect to output, income, employment, and value-added tax. The results of the I-O model indicate that in 2011, rural tourism development generated 1,387 billion Won of output impact, 287 billion Won of income impact, 275 billion Won of value-added impact, and 41,127 full-time jobs, respectively throughout direct, indirect, and induced effects. In particular, the restaurant sector had relative higher output and employment multipliers as compared to other industries, whereas they had lower multipliers of income and value-added than any other industries. The findings imply that the restaurant sector was relatively labor-intensive industry, generating high impact of employment effects.

The nucleotide sequences of a male-specific marker sex determining region Y (SRY) gene and a mitochondrial cytochrome B (CYTB) gene were characterized and analyzed to establish a molecular method for identification of species and sex of Korean roe deer (Capreolus pygargus tianschanicus). Similarity search result of SRY sequences showed very similar result to those reported in Moose (Alces alces) and Reindeer (Rangifer tarandus), both of which had 95.9% similarity in identity. CYTB genes were very similar to those reported in Siberian roe deer (C. pygargus pygargus) which had 98.6% similarity and not to European roe deer (C. capreolus), suggesting that the DNA samples tested were of Siberian roe deer lineage. Polymerase chain reaction (PCR)-based sex typing successfully discriminated between carcasses of male and female roe deer. Males had SRY band on agarose gels and females did not. The result of this molecular sex typing provided similar information with that obtained by genital organ observation. Therefore, this molecular method using male specific marker SRY and mitochondrial CYTB genes would be very useful for identification of the species and sex of the carcass remains of roe deer.

We conducted a survey on pepper virus diseases in 31 regions in Korea from November 2001 to December 2004. Using electron microscopy, test plant reaction, rapid immuno-filter paper assay (RIPA), reverse transcription-polymerase chain reaction (RT-PCR) and/or analysis of viral nucleotide sequences, we found a number of viruses from 1,056 samples that we collected. These included Cucumber mosaic virus (CMV), Pepper mottle virus (PepMoV), Pepper mild mottle virus (PMMoV), Broad bean wilt virus 2 (BBWV2), Tobacco mild green mosaic virus (TMGMV), and Tomato spotted wilt virus (TSWV). Of the samples analyzed, $343(32.5\%)$ were infected with CMV, $209(19.8\%)$ with PepMoV, $141(13.4\%)$ with PMMoV, $12(1.1\%)$ with BBWV2, $40(3.8\%)$ with TMGMV, $5(0.5\%)$ with TSWV, $153(14.5\%)$ with CMV and PepMoV, $54 (5.1\%)$ with CMV and PMMoV, $31(2.9\%)$ with PepMoV and PMMoV, $3(0.3\%)$ with CMV and BBWV2, $1(0.1\%)$ with CMV, PepMoV and BBWV2, $8(0.8\%)$ with CMV, PepMoV and PMMoV, and $30 (2.8\%)$ samples were infected with viruses which were not identified. CMV was the most predominant virus in all inspected fields and the number of the samples infected with PMMoV was relatively low as compared PepMoV infection level in pepper. TMGMV was only found in the southern part of Korea, while TSWV was isolated in Anyang and Yesan. However, we did not encounter in this survey the Alfalfa mosaic virus (AMV), Potato virus Y (PVY), Tobacco mosaic virus (TMV), and Pepper vein chlorosis virus (PVCV).

Purpose: To analyze the data of patients who suffered trauma in a cultivator accident and visited the trauma center in rural Gyeongbuk Province. Methods: We retrospectively reviewed the medical records and Korean Trauma Data Bank data of 120 patients who suffered cultivator-related traumas and visited the rural regional trauma center in Gyeongbuk Province from January to December 2015. Results: The age of the patients ranged from 35 to 96 years (mean, 70 years). Ninety-one (75.8%) patients were men, and twenty-nine (24.2%) were women. Most of the patients were in their 70s (46 men [50.5%] and 13 women [44.8%]). In total, 113 patients (94.1%) arrived at the regional trauma center by ground transport and 7 (5.9%) arrived by air transport. Ninety-eight patients (81.7%) were transported to the regional trauma center directly from the scene of the accident, and twenty-two (18.3%) were transferred from another medical institute. The mean time from the accident to arrival at the emergency department was 139 minutes, and only 46 patients (38.3%) arrived within 1 hour. Twelve (10.0%) patients died, including two deaths on arrival and two post- cardiopulmonary resuscitation deaths in the emergency department. All deaths were of male cultivator operators. The causes of death were shock (hypovolemic, traumatic, or septic), subdural hematoma (open), hemothorax, rhabdomyolysis, and pneumonia. Conclusions: As the government - led regional trauma center project is on process, it would be clinically important to summarize the initial outcome of cultivator injuries, which are characteristically found more in regional trauma centers in the rural area, and have high mortality. Based on this study, in the future, it will be necessary to follow up and analyze more number of patients and to construct accurate database about trauma cases related to cultivator in Gyeongbuk region.

During the 2012 growing season, 154 leaf samples were collected from sweet cherry trees in Hwaseong, Pyeongtaek, Gyeongju, Kimcheon, Daegu, Yeongju and Eumseong and tested for the presence of Cherry green ring mottle virus (CGRMV). PCR products of the expected size (807 bp) were obtained from 6 samples. The PCR products were cloned and sequenced. The nucleotide sequences of the clones showed over 88% identities to published coat protein sequences of CGRMV isolates in the GenBank database. The sequences of CGRMV isolates, CGR-KO 1-6 shared 98.8 to 99.8% nucleotide and 99.6 to 100% amino acid similarities. Phylogenetic analysis indicated that the Korean CGRMV isolates belong to the group II of CGRMV coat protein genes. The CGRMV infected sweet cherry trees were also tested for Apple chlorotic leaf spot virus (ACLSV), Apple mosaic virus (ApMV), Cherry necrotic rusty mottle virus (CNRMV), Cherry mottle leaf virus (CMLV), Cherry rasp leaf virus (CRLV), Cherry leafroll virus (CLRV), Cherry virus A (CVA), Little cherry virus 1 (LChV1), Prune dwarf virus (PDV) and Prunus necrotic ringspot virus (PNRSV) by RT-PCR. All of the tested trees were also infected with ACLSV.

Lactic acid bacteria were isolated from silage, which produce high level of hydrogen peroxide in cell culture supernatant. The 16S rDNA sequences of the isolate matched perfectly with that of Lactobacillus fermentum (99.9%), examined by a 16S rDNA gene sequence analysis and similarity search using the GenBank database, thus named L. fermentum CS12-1. L. fermentum CS12-1 showed resistance to low pH and bile acid. The production of hydrogen peroxide by L. fermentum CS12-1 was confirmed by catalase treatment and high-performance liquid chromatography. L. fermentum CS12-1 accumulated hydrogen peroxide in culture broth as cells grew, and the highest concentration of hydrogen peroxide reached 3.5 mM at the late stationary growth phase. The cell-free supernatant of L. fermentum CS12-1 both before and after neutralization inhibited the growth of enterotoxigenic Escherichia coli K88 that causes diarrhea in piglets.

Lily mottle virus (LMoV) causes flower quality reduction in Lilium spp. The coat protein gene was RT-PCR-amplified from total RNA extracted from infected lily leaves and the amplified fragment was cloned into the pRSET expression vector tagged with a His-MBP. The plasmid of recombinant coat protein was used to transform an Escherichia coli strain pLysS and was expressed. The coat protein was purified by affinity chromatography using a Ni-NTA resin. The identity of the purified protein was confirmed by SDS-PAGE. The in vitro-expressed protein was used for immunization of mice. The polyclonal and monoclonal antibodies reacted specifically for the detection of LMoV in lily extracts in Western blot. Moreover the monoclonal antibodies reacted with lily extracts in DAS-ELISA with no unspecific or heterologous reactions against other non-serologically related viruses, but the polyclonal antibodies revealed a weak reaction against both infected lily and healthy control.

This study describes a phytoplasmal disease occurring in Petunia leaves grown in the glasshouse of the National Horticultural Research Institute, Suwon, Korea. Abnormal growth like flattened stem with flower malformation or phyllody was observed from the plant. The DNA extracted from the diseased leaves was amplified using a universal primer pair of P1/P6 derived from the conserved 16S rRNA gene of Mollicutes giving the expected polymerase chain reaction(PCR) product of 1.5 kb. In the nested PCR assays, the expected DNA fragment of 1.1 kb was amplified with the specific primer pair R16F1/R16R1 that was designed on the basis of aster yellows(AY) phytoplasma 16S rDNA sequences. The 1.1 kb PCR products were cloned and nucleotide sequences were determined, and the sequences of the cloned 168 rRNA gene were deposited in the GenBank database under the accession no. of EU267779. Analysis of the homology percent of the 168 rDNA of PFS-K showed the closest relationship with Hydrangea phyllody phytoplasma(AY265215), Brassica napus phytoplasma(EU123466) and AY phytoplasma CHRY(AY180956). Phytoplasma isolated from the diseased Petunia was designated as Petunia flat stem phytoplasma Korean isolate(PFS-K) in this study. Flattened stem occurring in Petunia was confirmed as infection of AY group of phytoplasma by determination of 16S rRNA gene sequences of phytoplasma and microscopic observation of phytoplasma bodies. This is the first report on the phytoplasmal disease in Petunia in Korea.

This paper examines the impacts of credit on income inequality in Vietnam. Though it is one of the most common measures of financial development, there is a dearth of research in this area. Unlike previous studies, the paper disaggregates the impact of each type of credit on income inequality, looking at the Gini coefficient. We employ the Generalized Method of Moment (GMM) to solve the endogenous problem. The primary data set contains a panel of 60 Provincial observations, from data collected from the General Statistics Office of Vietnam from 2002 to 2016. The empirical findings show that, while commercial credit increases income inequality, policy credit contributes to reducing income inequality in Vietnam. The results also confirm the important roles of education, institutional quality and foreign direct investment in fighting against income inequality in Vietnam. However, the paper does not provide adequate evidence to support the inverted U-shaped relationship between credit and income inequality. Based on the findings, we argue that the government should direct flows of credit to real economic activities rather than speculative investment; more bank credit should be allocated to rural areas and agriculture; and favorable credit programs should be designed to promote education, especially of those living in rural areas.
