Heavy metals in soils exist in various forms dependent upon surrounding conditions. As the Janghang smelter area is of concern for its high elevated heavy metal concentrations, Korean government decided to remediate the area. Main objectives of this research were; to analyze heavy metal concentrations and their existing forms in the vicinity of the smelter; and to understand differences made by analysis techniques of heavy metals. Top soils of rice field, crop field, bare field, and forestry in the area were sampled and analyzed for their physicochemical characteristics. Concentrations of Cu, Cd, Pb, and As were analyzed with two pretreatment techniques adopted using 0.1 N HCl and aqua regia. To analyze existing forms of heavy metals, Tessier's schemes for sequential extraction technique were adopted. Exchangeable fraction and carbonate bound fraction of heavy metals may pose potential threat to environment and were in the order of Pb > As > Cu > Cd. If assessing mobile fraction of heavy metals by land uses, the order was forestry > bare land > crop field > rice field. When analyzed using Tessier's scheme, high ratio of residual fractions to total arsenic concentration should be considered for remediation design of the area.

The primary objective of the current work was to develop a standardized retrofit hull form capable of saving energy based on existing vessels. The bow shape of existing vessels was investigated, giving consideration to design draft and speed. Resistance performances were assessed for existing vessels according to operating conditions. Commercial CFD codes and model test materials were used for assessment of effective power. Three retrofit hull forms with minimum resistance were selected given real operating conditions. These vessels were named after customized ready-made hull forms to enable ship owners to make easier choices. The effective power of each vessel was estimated under real operating conditions. Subjects were operated with the lowest draft, and performance for retrofit No. 3 showed an 11-16% improvement in effective power at low speed ranges of 16-18 knots compared to existing vessels. When operated with a middle draft, performance for retrofit No. 3 showed a 6-11% improvement in effective power at low speed ranges compared to existing vessels. When operated with the highest draft, performance for all vessels showed little difference in effective power.

The purpose of this study is to improve the productivity and constructability of permanent forms. The permanent forms will cut down the cost of production and make easier to install in the field; hence increase the use of forms in the today's market. The permanent form is produced in the factory and built in field. So this study is in two parts. The one is the productivity in factory, the other is constructability in the field. This study is the designing a new mold system as a solution to existing mold system's problems.

The purpose of this research is to find som ways to model tree forms more efficiently in reference with surveying structural data and handling parameters in plant Editor of AccuRender, the AutoCAD-based rendering software adopting the procedural plant modeling technique. In case of modelling a new tree, because it is efficient to modify an existing tree data as a template, we attempted to classify 81 species' data from existing plant library including conifers and deciduous tree. According to the qualitative characteristics and quantitative parameters of geometrical and branching structure, 8 types of tree form were classified with factor and cluster analysis. Some critical aspects found in the distributions of standardized scores of parameters in each type were discussed for explaining the tree forms intuitively. For adaptability of the resulted classification and typical parameters, 10 species of tree were measured and modelled, and proved to be very similar to the real structures of tree forms. CG or CAD-based plant modelling technique would be recommended not only as a presentation tool but for planting design, landscape simulation and assessment.

This paper suggests a systematic methodology to predict chip forms using the experimental design technique and the neural network. Significant factors determined with ANOVA analysis are used as input variables of the neural network back-propagation algorithm. It has been shown that cutting conditions and cutting tool shapes have distinct effects on the chip forms, so chip breaking. Cutting tools are represented using the Z-map method, which differs from existing methods using some chip breaker parameters. After training the neural network with selected input variables, chip forms are predicted and compared with original chip forms obtained from experiments under same input conditions, showing that chip forms are same at all conditions. To verify the suggested model, one tool not used in training the model is chosen and input to the model. Under various cutting conditions, predicted chip forms agree well with those obtained from cutting experiments. The suggested method could reduce the cost and time significantly in designing cutting tools as well as replacing the“trial-and-error”design method.

The purposes of this study are to examine clothing businesses which are using dress forms and grasp the problems in apparel manufacturing process, to verify the size and shape of the dress forms for uniformity, to ascertain the uniformity between the dress forms being sold today and the somatotype of the target consumers. The following results were obtained. First, most of the clothing businesses used the existing dress forms in the company. The dress forms didn't reflect the somatotype of the current consumers. And the users satisfaction was below the average. Second, the size and shape of the dress forms being sold today had lack of uniformity between themselves. Third, the dress forms didn't reflect the shape characteristics as well as the size of the target consumers. Consequently, The dress forms need to have the following. First, It is necessary that the dress forms have various functions in a dress form in the future. Second, to get high satisfaction of clothing fit, we need to build up the data base of the consumers somatotype. The data base have to consist of not only circumference but also width, thickness, angle of the current consumers. Last, the further studies of the dress forms need to meet the clothing businesses demand.

This study develops 1/2 dress forms for draping. This study investigated the production status of domestic and foreign products in order to model their shape using CLO 3D. In addition, it developed torso-type and torso-crotch-type products that allowed for draping using a 3D printer. This study analyzed shape and size compared to developed ones after referring to the Size Korea 7th Survey data as well as seven domestic and foreign company websites. The results are follows. First, an investigation of the production status of the products for the size of most of the domestic ones (except K-4) indicated that the waist circumference was slimmer than Size Korea. Bust, waist, and hip circumferences ranged from 42.0 cm, 32.0 cm, and 45.0 cm - 49.0 cm, respectively, in Chinese products; 42.0 cm - 43.0 cm, 30.5 cm - 31.5 cm, and 46.0 cm - 46.5 cm in Japanese products; 43.0 cm, 35.0cm, and 46.5 cm in American products (Japanese body shape applied). Second, an avatar was produced on a 3D software with the average size of 20-24year-old women, and its file modified as a dress form for 3D printing with PLA filament to produce dress forms for draping, workable with pins, using quilting cotton and cotton cloth. Third, the comparisons of the form and flattening between the developed dress forms and the selling ones indicated that flattening was bigger in the waist part of the former than the latter. The waist is produced too slim in the existing dress forms; therefore, it is necessary to correct the waist circumference. Unlike existing dress forms, the developed ones were produced in proximity to the average size of 20-24 year-old women in the Size Korea 7th Survey.

This paper presents the effectiveness of cold weather concreting by applying both anti-freeze agent and insulating forms developed through previous study investigating insulating effects on the concrete and the strength gain. According to test results, in $-10^{\circ}C$ of air temperature, when euroforms are applied, the temperature of plain concrete drops below $0^{\circ}C$ and maintains its temperature during early 24 hours. However, when insulating forms are applied, the temperature of concrete keeps 8~$13^{\circ}C$ during first 24 hours. Insulating forms has better performance on insulating effects than existing euroforms. Concrete containing anti-freeze agent shows temperature rising effects about $1^{\circ}C$ compared to plain concrete. Strength gain of core concrete shows higher when insulating forms is applied.
