The objectives of the study are to analyze the impacts of rural road project on the social and economic activities of community people, offer basic data to perform evaluation of the project, and suggest future directions of the project. Research methodology adopted is a questionnaire method. There were interviewed 281 adult residents selected from 34 villages in Yeongdong-gun(mountainous), Miryang-si(middle), and Gochang-gun(plain). Results of the study are as follows: 1) Increase of income and land prices in mountainous and middle regions by the rural road project is higher than in plain; 2) Most inconvenient road expressed by the interviewee is the one linking farm and residence and 3) The problems of rural roads derived are narrowness, unpavement and partial pavement, unreliable maintenance, and long construction time. In order to meet the community needs on rural roads, it may be necessary that community people participate in the process of the project. And it is desirable to put priority on expanding and paving existing roads rather than constructing new one.

The potential biological activities of water and ethanol extracts from two varieties of Rubus coreanus Miquel fruits produced in the Gochang-gun (GR) and Hoengseong-gun (HR) regions of Korea were examined. The hydroxyl radical ($\cdot$OH) scavenging activity, reducing power, lipid peroxidation inhibitory activity, and antiproliferative activity on cancer cells by these extracts were examined, and $\alpha$-amylase and $\alpha$-glucosidase inhibition assays were also performed. The EtOH extract from GR showed high hydroxyl radical scavenging activity ($EC_{50}=119.47{\pm}5.13\;{\mu}g/mL$), lipid peroxidation inhibitory activity ($EC_{50}=213.45{\pm}3.14\;{\mu}g/mL$) and a concentration dependence, with OD values ranging from 0.15 to 0.56 (50 to 200 ${\mu}g/mL$), for reducing power. The EtOH extract from GR has the highest antiproliferative activities on MDA-MB-231 and HepG2 cancer cells among four extracts. Meanwhile, all extracts showed certain $\alpha$-amylase and $\alpha$-glucosidase inhibition activities. These results indicate that extracts from two varieties of R. coreanus fruits have significant antioxidant, anti-diabetic and anti-tumorigenic activities, which suggest these extracts could be a potential source for pharmaceutical.

Until now, occurrence of Rice black-streaked dwarf virus (RBSDV) is observed in Gyeongsang provinces, southeastern part of Korea. However, recently, the occurrence of RBSDV is increasing and spreading in Jeonra provinces including Gochang-gun, southwestern part of Korea. RBSDV infected plants showed typical symptoms including stunted, deformed leaves with white waxy or black-streaked swelling along the veins. We extracted viral genomic dsRNA from infected leaves and analyzed dsRNA pattern by polyacrylamide gel electrophoresis. Ten genomic segments with similar sized dsRNAs were observed. We also detected RBSDV by reverse transcription (RT)-PCR using specific primers for S10 from genomic dsRNA and observed amplified DNA fragment specific for RBSDV S10.

The outbreak of lumpy skin disease (LSD), caused by LSD virus (LSDV), in Jeollabuk-do was first confirmed at a Korean cattle farm in Buan-gun on October 24, 2023. Afterwards, thirteen cases (twelve cases in Gochang-gun and a case in Imsil-gun) were further confirmed, resulting in a total of fourteen cases over 25 days until November 17, 2023. Clinical examination were conducted on infected and co-habitting cattle from the LSD-affected farms with particular focus on the presence of nodules throughout the body such as head, neck, chest, femur, head, and perineum. As a results, abnormal clinical signs were observed in fifteen cows: loss of appetite in six cows, high fever in three cows, eye mucosal nodules in a cow, nasal mucosal nodules in six cows, nodules on perineum in five cows, scrotum nodules in two cows, papillary nodules in a cow, and/or skin nodules in eleven cows. By the PCR methods, the common gene of capripox virus and/or the specific gene of LSDV were detected in 35 of the 69 cows tested this study. In the Farm1, capripox virus-specific gene, LSDV wild strain-specific gene, and LSDV vaccine strain-spcific gene were simultaneously detected in affected cows, indicating the cattle farm was affected by various strain of LSDV. As a result of combining clincal examination and PCR test, it was found that clinically and subclinically infeted cows coexist in the LSDV-infected farms. These finding in this study will be a great help in diagnosis and prevention of the LSD in Korean cattle farms.

Dust samples were collected from 10 middle and high schools in the Gochang-Gun, Korea. Heavy metal concentrations were determined for the dry-deposited dusts from indoor and outdoor of classroom and playground of each sampling site. Concentrations of Cd, Cu, Pb and Zn in indoor's dusts were highly concentrated. Also concentrations of Cu, Ni, Pb and Zn in outdoor's dusts were highly concentrated. Concentrations of Cd, Cu and Zn in the dusts were much higher than the world average contents in soil and environmental orientation value. These levels are similar to those of the dust samples at middle schools and high schools located in Jeonju-city, Korea. Compared with concentrations of heavy metals in soils and dusts in Korea, the environment of indoor and outdoor of classroom is highly concentrated except for Cu, Zn. The concentrations of playground is less than that of residential dust and main road dust and playground in Jeonju-city. Playground dusts in 1 school exhibited the enhanced heavy metal pollution with a pollution index (Kloke, 1979) greater than 1.0, but indoor and outdoor dusts in 7 schools exhibited the enhanced heavy metal pollution with a pollution index (by Kloke) yester than 1.0.

This study was intended to evaluate the objective landscape of rural region using an additive integration index method in the Seondong region of Gochang-gun, Jeollabuk-do, Korea. This study consisted of the following three steps. First, this study developed an additive integration index calculation model for landscape assessment based on indicators and weight to each space type in accordance with three landscape fields which were developed by the expert Delphi method. Second, this study used NDVI (Normalized Difference Vegetation Index) and permeable area rate, which were available from high resolution satellite image, to calculate the green naturality degree, area rate, and building coverage respectively. Third, this study has calculated the landscape assessment index of rural regions using an additive integration index method made of assessment data and weight for each indicator. This study has found the following results: 1) landscape level was very poor in all 6 types of space, marking grade five; 2) while the highest level of natural landscape and mixed landscape was grade two, that of artificial landscape was grade five; 3) based on objective landscape, grade five showed the highest frequency, and grade one, two, three, and four followed in that order.

This study was carried out to provide data on current sod production in South Korea. Fifteen items were surveyed including production acreage, species and cultivars, experience on farming, production cost and the others during April to October in 2006. To estimate production acreage, 73 turfgrass growers were interviewed. Estimated acreage for turfgrass production was 2,947 ha. Acreages by province were 1,417 ha in Jeollanam-do(48%), 442 ha in Jeollabuk-do(14.9%), 344 ha in Gyeonggi-do(11.6%), 248 ha in Gyeongsangnam-do(8.4%), and 240 ha in Chungcheongnam-do(8.1%), respectively. The major sod producing regions were Jangseong-gun, Hampyeong-gun, Yeonggwang-gun, Gochang-gun, Sacheon city, Iksan city, Yeoju city, Yeoncheon-gun. Percentage of turf growers over 50 years old was 72.4 percent, which means production was carried out mainly by old farmers. Grower's career over 10 years was 84.8%. Cultivated species and varieties were 'Junggi'(55.5%) of fine-textured Korean lawngrass, common Korean lawngrass(37.4%), Kentucky bluegrass(3.8%), and new zoysiagrass cultivars(0.1%), respectively. Sod size were variable. Sod size of $18{\times}18cm $ was 43.5 percent. Sales route was mainly through sod distributor(40.5%). Sod producing cost was $2,160{\sim}2,730$ won per square meter at Jeolla-do areas.

The physico-chemical properties of the rainfall interception culture (85 sites) and the open field culture soils (85 sites) in the area of Gochang-gun, Jeollabuk-do were surveyed. Soil textural distribution of the rainfall interception culture and the open field culture soils was 74% and 64% for silt loam, 16% and 35% for loam, and 10% and 1% for clay, respectively. The percentage of aggregate rates was higher in the open field culture soils (60.06%) than rainfall interception culture soils (55.84%). Electrical conductivity, exchangeable cations, and anions in the rainfall interception culture soils were higher than those in open field soils. Specially, accumulated amount of anion in rainfall interception culture soils was remarkably higher 2~3 times than open field culture soils. The results from the analyses of rainfall interception culture soils suggested that the most critical problem is the salts accumulation caused by over-fertilization of chemical fertilizer and compost. Therefore, application rates of chemical fertilizer and compost should be controlled in order to conservation of soil and water for sustainable agriculture.

A newly recorded species, Schoenoplectiella ${\times}$uzenensis (Ohwi ex T. Koyama) Hayasaka, was found in Chosan Lake, Gosu-myeon, Gochang-gun, Jeollabuk-do, Korea. Schoenoplectiella ${\times}$uzenensis differs from its related species in having short rhizomes and 1 to 3 spikelets showing inflorescence. Schoenoplectiella triangulata has very short rhizomes and 520 spikelets with inflorescence. Schoenoplectiella lineolata has long creeping rhizomes and 1 spikelet showing inflorescence. We propose the new Korean name of 'Go-Chang-Go-Rang-Ei' based on its initial collection site. A description, line drawing, color photographs, table, and a species key of Korean Schoenoplectiella are provided for species identification.

Life cycle stages, including daughter sporocysts, cercariae, and metacercariae, of Parvatrema duboisi (Dollfus, 1923) Bartoli, 1974 (Digenea: Gymnophallidae) have been found in the Manila clam Ruditapes philippinarum from Aphae-do (Island), Shinan-gun, Jeollanam-do, Korea. The daughter sporocysts were elongated sac-like and 307-570 (av. 395) ㎛ long and 101-213 (av. 157) ㎛ wide. Most of the daughter sporocysts contained 15-20 furcocercous cercariae each. The cercariae measured 112-146 (av. 134) ㎛ in total length and 35-46 (av. 40) ㎛ in width, with 69-92 (av. 85) ㎛ long body and 39-54 (av. 49) ㎛ long tail. The metacercariae were 210-250 (av. 231) ㎛ in length and 170-195 (av. 185) ㎛ in width, and characterized by having a large oral sucker, genital pore some distance anterior to the ventral sucker, no ventral pit, and 1 compact or slightly lobed vitellarium, strongly suggesting P. duboisi. The metacercariae were experimentally infected to ICR mice, and adults were recovered at day 7 post-infection. The adult flukes were morphologically similar to the metacercariae except in the presence of up to 20 eggs in the uterus. The daughter sporocysts and metacercariae were molecularly (ITS1-5.8S rDNA-ITS2) analyzed to confirm the species, and the results showed 99.8-99.9% identity with P. duboisi reported from Kyushu, Japan and Gochang, Korea. These results confirmed the presence of various life cycle stages of P. duboisi in the Manila clam, R. philippinarum, playing the role of the first as well as the second intermediate host, on Aphae-do (Island), Shinan-gun, Korea.
