이 글에서는 익산 쌍릉의 묘제 및 목관의 특징과 그 역사적 의미를 살펴보았다. 쌍릉은 묘제와 장제 뿐만 아니라 옥장신구와 같은 부장유물 그리고 익산과 무왕의 관계를 통해서도 무왕과 그 비의 능임을 확인할 수 있다. 익산에 백제 왕릉, 즉 무왕릉이 조영된 이유는 여러 측면에서 살펴볼 수 있다. 우선 사비가 아니라 익산을 기반으로 왕이 된 무왕이 익산을 중요시한 것은 당연하다. 또한 신라와의 관계에서 익산의 지정학적 중요성도 익산 경영의 요인이 되었다. 익산에 도성의 경관을 이루는 주요시설을 세운 것은 천도 혹은 그에 준하는 행위의 준비와 일부 실행을 보여준다. 다만 귀족과 사서인(士庶人)의 거주구역 등 도시로 완성된 모습을 보이지 않은 것은 그것이 완전하지 못하였음을 시사한다. 그렇지만 무왕 사후에도 익산의 중요성은 의자왕에 의해 유지되었다. 그것은 무왕 재위 후반기에 창건된 제석사 및 미륵사와 같은 대사찰이 백제 멸망 때까지 계속 운영된 점이나 사찰로 전용되었지만 왕궁 일원이 여전히 존속된 점을 통해서 알 수 있다. 이러한 계승의식이 무왕과 그 비의 능을 익산지역에 조성하는 행위로 구체화되었다고 할 수 있다.

We have studied cytotoxicity of S-nitroso-N-acetyl- N-DL-penicillamine(SNAP), a Nitric oxide (NO)-releasing compound, in RAW264.7 macrophages. SNAP is cytotoxic to RAW264.7 cells in a concentration-dependent manner. PMA(200 nM) stimulated cells to produce superoxide anton radical($O_2^{-\cdot}$) and caused a little loss of RAW264.7 cell viability for 12 hr and diminished the cytotoxicity of SNAP. The mechanism by which PMA can protect cells against NO-mediated cytotoxicity was studied by peroxynitrite-enhanced chemiluminescence method. Observed results suggested that $O_2^{-\cdot}$ produced by PMAstimulated RAW264.7 cells may quench NO released by SNAP and reduce NO, thus attenuating NO-related damages.

Spikelet and vascular bundle development in rice panicles is considered to be the important elements in determining the genotype's yield capacity and translocation ability of assimilates into grains, respectively. This study was conducted to clarify the varietal differences of the spikelet and vascular bundle formations among three rice cultivars; Iksan 435 (japonica), Dongjinbyeo (japonica) and Namcheonbyeo (Tongl-type). Iksan 435 had more primary rachis branches (PRBs), secondary rachis branches (SRBs) and spikelets per panicle than Dongjinbyeo, but less than Namcheonbyeo. Among three cultivars, Namcheonbyeo showed the highest spikelet number per panicle which were differentiated SRBs mainly on PRBs of lower rachis nodes. And Namchenbyeo showed the highest number of large vascular bundle (LVB) as well as small vascular bundle (SVB) and it displayed the largest diameter of LVB. Between the two japonica cultivars, the numbers of LVBs end SVBs were significantly higher in Iksan 435 than those in Dongjinbyeo. The PRBs to LVBs ratio of Namcheonbyeo was twice as large as those of Dongjinbyeo and Iksan 435. These results indicate that the newly bred cultivar, Iksan 435, has improved yield capacity by increasing the number of especially rachis branches and spikelets formation as well as 1,000 grain weight, compared to other former japonicas.

Iksan370 is a long-spike wheat developed by the Rural Development Administration yielding excellent features components such as cold resistance, disease resistance, and viviparous germination. The physicochemical and material properties of the raw wheat and milled flour of Iksan370 were analyzed to derive its appropriate uses. The raw wheat of Iksan370 showed high contents of ash and proteins at 1.71% and 13.7%, respectively. Its test weight of 763.0 g/L was similar to those of other varieties and its 1,000 kernel weight was high at 45.38 g. The milled flour of Iksan370 had an ash content of 0.45%, which corresponds with a class 1 flour, and its protein content is 12.18%, corresponding with strong flour. The damaged starch was 5.41%, which was lower than that of other varieties. The average grain size was $70.67{\mu}m$ and the grain distribution was at the level of a typical hard wheat. In the farinogram, the water absorption was 58.63%, which corresponded to the level of medium flour. The development time was 7.00 minutes, which was significantly lower than those of Jokyung and Keumkang. The degree of softening was 67.00 BU, similar to those of Yunbaek and Baekjoong. Among the physico-chemical characteristics, the high protein content and typical hard wheat grain distribution of Iksan370 were similar to those of strong wheat, usually used for bread making. However, in the farinogram, the dough development time was short and the degree of softening was high. As a result, Iksan370 was expected to have poor breadmaking properties and a small volume of the final bread product due to insufficient dough durability. On the other hand, Iksan370 showed the highest maximum gelatinization viscosity at 864.00 BU. Therefore, Iksan370 is expected to show glutinous texture when used for noodles and its flour appears to be appropriate for frying powders as well.

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.

This study was carried out to investigate the dietary behaviors and nutrient intake of high school girls in Iksan and Seoul cities. The subjects consisted of 122 students in Iksan city, and 136 students in Seoul city. The proportion of subjects who eat meals irregularly was higher in Iksan ($94.8\%$) than in Seoul ($80.9\%$). The proportion of subjects who skip meals was also higher in Iksan ($61.5\%$) than in Seoul ($56.6\%$), and most of them ($69.7\%$) skipped breakfast, even thought they thought that it was the most important meal ($86.4\%$). The subjects tended to overeat at lunch ($41.9\%$) and dinner ($55.4\%$). The main reasons that the subjects skipped a meal were a lack of time (50.7%) and poor appetites ($23.7\%$). Most of the subjects ($57.4\%$) had tried to control their body weight by taking drugs ($40.5\%$), doing exercise ($34.5\%$), and controlling their diet ($25\%$). The average intake of nutrients and energy was significantly higher (P<0.05, p<0.01) in Iksan than in Seoul. The intake was below the RDA recommendations except for phosphorus in I ksan, but was above it except for calcium, iron, and vitamin B2, in Seoul. The indexes of nutritional quality (INQ) of calcium (0.5), iron (0.6), vitamin A (0.8), vitamin B2 (0.7), niacin (0.9), and vitamin C (0.9) were under 1.0 but those of protein (1.0), phosphorus (1.2) and thiamin (1.0) were over 1.0. The INQ of the other nutrients, except protein and vitamin C, was significantly higher in Seoul than in Iksan.

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.

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.
