  • This study aims at investigating the undrained behavior of the normally consolidated clay foundation using single hardening constitutive model based on elasticity and plasticity theories. The specimen employed was sampled at Mooan near the down stream of Young San river and remolded into consolidation apparatus. 11 soil parameters for the model was determined from simple tests such as isotropic compression and consolidation undrained triaxial compression tests. FEM program to predict the undrained behavior of the foundation was developed and back analysis was performed to verify prediction ability of the FEM program. Finally plate load test on the 2-dimensional model foundation was carried out in order to compare numerical analysis and observed values on the foundation.

  • This study was conducted to examine the yield of lotus leaves and roots per one native white lotus grown in Hoesan, Muan of Jeonnam districts, which were promoted by Muan-Gun, Jeonnam as a local speciality. We planted the rhizomes with 2 internodes in a rubber pot in the middle of April. Then on September, 24, 2008, we dug out the main rhizomes and it had grown by 810cm. From the data, the leaf area was $34,442\;cm^2$, the fresh leaf weight was 1,230g, and the dry leaf weight was 235.4g. The weight of the edible fresh stalk and dry weight leaf were 1,325g and 164.3g. Yield of the white lotus root were 1,480g on Sept. 4, 3,880g on Sept. 20 and 4,172g on Oct. 18. Native white lotus are able to be harvested early as September, however, it is be better that it is harvested in the middle of October based on the yield.

  • Larval densities and spatial distribution patterns of beet armyWorm, Spodoptera exigua, were studied in the welsh onion field located in Asan from June to November, 1991. During the period, there were two denslty-peaks;mid August and mid~late September. The larvae showed clumped distribution patterns. but the patterns changed into random as larval density decreased in Oct.ober. Each larval instar showed clumped pattern expect 6th instar surveyed on September 25, which distributed in a random pattern. The larval distribution pattern were also influenced by the host plants;clumped pattern on such host. as red pepper and welsh onion, versus random pattern on such hosts as chrysanthemum, peanut and soybean.

  • To find out the optimum fertilizer level for onion, early maturing cultivar Fechongjoseng, experiment with four fertilizer levels was conducted of the field of the paddy and upland in Muan and Changyeong from Sep.1993 to Feb.1995. The yield character of onion was higher and rate of the rottenness was lowest under the treatment of $N-P_2O_5-K_2O$=28-9.5-23Kg/10a in the soil of paddy and upland field of Muan area. But the onion yield was excellent and rate of the rottenness was lowest under the treatments, $N-P_2O_5-K_2O$=21-19-17.3Kg/10a, in the soil of paddy field and $N-P_2O_5-K_2O$=28-9.5-23Kg/10a, in the soil of upland field of Changyeong area.

  • We investigated the species richness of lepidopteran insects (excluding butterflies and microlepidoptera) of Mt. Seungdal-san, Muan-gun, Jeollannam-do, Korea, from 2003 to 2005 using two portable light traps. A total of species comprised 423 species belongs to 17 families were identified. The family Noctuidae with 209 species was dominant in the area followed by Geometridae with 132 species. Based on the number of individuals collected, Geometridae was the highest mostly due to an ennomine species (Alcis angulifera). Monthly fluctuations of moth species richness present an M-shaped curve with two high peaks at June and August. Comparisons of species diversity of yearly captures revealed that the diversity of 2003 was higher than that of 2004, but the diversities of between 2003 and 2005, and between 2004 and 2005 were no different.

  • Recently, 3D integral imaging system, which is well known as an auto-stereoscopic 3D display method, has been gaining great attention amongst researchers. The integral imaging is a promising 3D display technology since it is able to deliver continuous viewing points, full parallax, and full color view to the observers in space. In this paper, we propose a novel interactive 3D integral imaging system using a single camera. The user interface is implemented by adding a camera in the conventional integral imaging system. To show the possibility of the proposed system, we implement the optical setup and present the preliminary results. To our best knowledge, this is the first time to study an interactive 3D integral imaging.

  • Stability of yield and yield components in 6 cotton cultivars were evaluated using data from the regional yield trials at two sites from 1987 to 1990. Genotype-environment interactions were analyzed by the modified model of Eberhart and Russell. The results revealed that Mokpo 7, which had many effective number of bearing branches and capsule, was the most stable high yielding variety over a wide range of environmental variations. bearing branches and capsule, was the most stable high yielding variety over a wide range of environmental variations.

  • In recent years, the developments in 3D technologies have initiated the commercialization of 3D services on mobile devices. For this purpose, stereoscopic 3D technology is used, which enables 3D TV on mobile devices including smartphone with glasses-free 3D viewing. As a result, the issues related with stereo imaging have been spotlighted greatly. Especially, three MPEG coding standards are provided for mobile 3D services, namely H.264/AVC with and without SEI message and H.264/MVC. In this respect, this paper presents an overview of developments in stereoscopic technologies for mobile devices to gain some perspective on the changes and progress. in this paper, we verified the availability of android based stereoscipic 3D technology related with mobile 3D TV and Smartphone with special emphasis on 3D video format and 3D features by various technollogy characteristics analysis.

  • This study evaluated the quality of meals served by the elementary schools in Muan based on nutrient contents and food diversity. The contents, nutrient densities and nutrient adequacy ratios(NAR) of most nutrients were higher than those calculated from the Korean RDA. However, the content, nutrient density, and NAR of iron were lower than those calculated from the RDA for 10 to 12 year old girls. The content of sodium was somewhat high. The average number of different kinds of food and dishes per meal were 19.2 and 6.0, respectively. The more the number of dishes, the higher the NARs of calcium, calories, niacin, phosphorus and protein. However, the NAR of iron showed no correlation with the number of dishes. The meals belonging to the food group intake pattern containing fruits had more vitamin C and fiber, and less protein, lipid, and phosphorus than those belonging to the food group intake pattern not containing fruits. In conclusion, the quality of nutrition of meals served by school lunch program(SLP) was considered fairly good. However, the nutritionists should consider the iron for 10 to 12 year old girls and cut down the amount of sodium. In addition, unless the children prefer the foods served by SLP or adjust to the general aspects of SLP, SLP can't accomplish its purposes. Therefore, we suggest that nutritionists should survey children's food preference and satisfaction with the general aspects of SLP.

  • DIBR (Depth Image Based Rendering) is a multimedia technology that generates the virtual multi-view images using a color image and a depth image, and it is used for creating glasses-less 3-dimensional display contents. This research describes the effect of depth accuracy about the objective quality of DIBR-based multi-view images. It first evaluated the minimum depth quantization bit that enables the minimum distortion so that people cannot recognize the quality degradation. It then presented the comparative analysis of non-uniform domain-division quantization versus regular linear quantization to find out how effectively express the accuracy of the depth information in same quantization levels according to scene properties.
