The purpose of this study was to investigate the seroprevalence of paratuberculosis in Korean cattle in western Jeonbuk area. From February 2012 to January 2013, blood samples were collected from 2,606 Korean cattle of 263 farms. As a result, 60 (2.3%) heads of 46 (17.5%) farms were positive on the ELISA test for paratuberculosis. Based on regional analysis, 18 (19.6%) out of 92 farms and 24 (2.5%) out of 941 heads in Iksan area, 28 (22.0%) out of 127 farms and 36 (2.8%) out of 1,291 heads in Kimje area were positive but samples from Gunsan area were all negative. According to scale breeding, small scale (below 50 heads) breeding showed the most high prevalence rate compared to middle (50 to 99 heads) or large (over 100 heads) scale breeding. To clarify the relation between number of heads and paratuberculosis prevalence, some additional analysis would be required in further, though.

This study aims to draw out planning principles and structure of Iksan imperial capital city in late Baekje, especially in view of the relationship among imperial capital city planning area, skeletal axis and the location of royal castle. With site survey and analysis of historical records, old maps, topographical maps, archeological excavation data, land registration map of 1915, some significant inferences were drawn out. Firstly from the point of topological conditions, the contiguous line of a stratum from Mireuk mountain(彌勒山) to Wangkung-ri castle(王宮里遺蹟) and two waterways made a topological axis of Iksan Imperial capital city. Secondly district of Iksan imperial capital city can be deduced to the inner area north to Kummado soil wall(金馬都土城), south to the confluence of Iksan river(益山川) and Busang river(扶桑川), west to Okum mountain fortress(五金山城) and Galjeon river(葛田川), east to line near to eastern wall of Jesuksa temple(帝釋寺). Iksan ssang-reung(益山雙陵) was located outside western boundary line of capital city. Thirdly axis from Wangkung-ri castle to northern Kummado soil wall made a skeletal axis of city structure. It got through northern lowland along Buk river(北川) between Yonghwa(龍華山) and Mireuk mountain. Fourthly the location of royal palace can be deduced to the north part of the city around Kumma town area along the planning principle of northern royal palace.

The study result on the domestic waste occurrence and admistration condition of Iksan City as follows ; 1. The year of 1995 has observed a radically decreasing ratio of per capita waste generation compared to the previous year by 26.2%, owing to the publication of the new amendment of volume based charge as well as to the rural population included through the merger of Iksan City and Iksan Country ; the daily quantity of domestic waste for Iksan residents in 1997 was calculated to be $0.66kg/capita{\cdot}day$. 2. Waste generation in nonresidential areas were $8.04kg/capita{\cdot}day$ in average ; the quantity per capita in market places was observed to generate the largest, $36.76kg/capita{\cdot}day$, while that of services was the smallest $0.25kg/capita{\cdot}day$. 3. The average generation per capita of household waste was $0.23kg/capita{\cdot}day$ in the area which has no volume based charge system. This area showed no difference from those of other areas ; the apparent density of the waste recorded the lowest $0.llkg/{\ell}$ for District Offices, while the highest among the classified fields was $0.40kg/{\ell}$ of the Fire Station. 4. Iksan City showed great contribution by decreasing the absolute quantity of waste for landfill by waste classfication, according to the days of the week and reutilizing recyclable waste since August, 1997. 5. Location of a landfill site for disposal of nonrecyclable waste will cause a serious problem to the community and it will be highly recommendable to have governmental support and professtional consultation as well as open discussions, such as hearings, for the settlement of the problem.

To assess the food intake and diet quality by the interrelationship of DDS and DVS of high school girls, this dietary survey was conducted with 253 subjects living in Iksan and Seoul areas using a 24-hour recall method. The average amount of total food intake was 1,133.2 g, with 79.9% of food intake being supplied by vegetable food and 20.1% by animal food and higher in Seoul area. The food consumed most frequently was rice, green onion, garlic, soy sauce, sesame oil, onion, and Kimchi. The food consumed in the largest amounts were rice(303.3 g), milk(62.2 g), and Kimchi(53.4 g). Diet quality was assessed by food group pattern, dietary diversity score(DDS), and dietary variety score(DVS). When investigating the consumption pattern of major five food groups(grain, meat, dairy, fruit, vegetable groups), nobody consumed all five food groups in each meal. The groups most frequently missing were fruits and dairy products. The average number of food consumed per day was 12.1(DVS) and Iksan area scored lower(11.7) on DVS than Seoul area(12.6). The higher DDS and DVS of subjects were, the more MAR and NAR of energy, calcium, vitamin A and C increased. The number of major food groups(DDS)(p<0.01, P<0.05) and that of food items (DVS)(p<0.01) correlated positively NAR(nutrient adequacy ratio) and MAR (mean adequacy ratio) significantly.

This study investigated characteristics of rainfall and water quality in Saemangeum area with attention to temporal and spatial distributions. A high variability in rainfall was noted during July and August. The temporal analysis of water quality data indicated that DO and TN as well as BOD, COD and SS were within national standards except for increased concentrations during spring and summer, unlike TP values that indicated poor water quality. Standard deviation showed a high variability in SS among the seasons most especially during summer. The high dispersion indicated variability in the chemical composition of pollutants where the temporal and spatial variations caused by polluting sources and/or seasonal changes were most evident for BOD and COD during winter and spring. The box plots and bar charts showed steadily low concentrations of BOD, COD, TN and TP except within Iksan and notable significant variations in SS concentrations among the monitoring stations. Thus, high pollution levels requiring intervention were identified in Mangyeong river basin with particular concern for areas represented by Iksan station. It was noted that Iksan received a considerable amount of rainfall which meant high runoff which could explain the significant pollution levels revealed in the water quality spatial distribution. Major pollution contributing pollutants within Saemangeum area were identified as SS, BOD, COD and TN. Therefore the present results could be used as a guideline for the temporal and spatial distributions analysis of both rainfall and water quality in Saemangeum watershed.

Modern railway construction by Japanese had a great influence on the urbanization, transformation of urban structure and landscape during the Japanese imperialism and compressive increasing period in Iri(Iksan). This paper aims to find out the effect of railway on the modern urban structure and urban landscape in Iri(Iksan). Railways in Iri, Honam railway, Kunsan railway, Jeonla railway have been constructed progressively during 1911 and 1915 with Iri and old Iri(east-Iri) station. From the analysis of land registration maps and street plans, old photographies and historical records, some significant features underling railway construction can be followed in view of modern urbanization process in Iri. Firstly railways cut off the possibility of developing urban structure based on traditional spatial structure of Iksan. Secondly railways made dual spatial structure in Iri. Japanese and Korean life zone were divided into separate district around urbanization area and market place. Thirdly traditional space cognition system based on four cardinal directions were changed to front and rear space of railway station. Fourthly railways and stations caused neo-baroque spatial order and imperialistic urban landscape of Iri with axis, vista and gridiron plan. Fifthly break points and fringe belts garbling modern urbanization process are created. Sixthly modern cultural and consumptive urban spaces were taken their seats in relation with daily urban life.

This article examined the burial type, wooden coffin and its historical significance of Iksan Ssangneung, the royal tombs of Baekje. Ssangneung was found to be the royal tombs of King Mu(武王) and queen through the burial type, wooden coffin, articles such as chinese jade ornaments and the deep relationship between King Mu and Iksan region. The reason of constructing Baekje royal tombs in Iksan region can be examined at many aspects. First, Iksan was a very important place for King Mu. Because Iksan was the basis of his political growth. Also, Iksan was a important geopolitical location in relation with Silla(新羅). For this reason, Iksan was developed in earnest. The construction of major facilities such as royal palace and temples in Iksan suggest the transfer of the capital from Sabi(泗?) or the preparation and partial execution at least. However, the transfer of the capital was not completed. It can be seen as the incomplete city. However, even after King Mu Iksan was maintained as the important region by King Euja(義慈王). It can be seen through the maintenance of great temples such as Jeseoksa(帝釋寺) and Mireuksa(彌勒寺) built at later period of King Mu and royal palace area, even though royal palace had turned into the temple. These inherited consciousness may have been embodied in the act of building royal tombs of King Mu and queen.
