This study was for reasonable gathering by a fabric and a skirt length. So the purpose of this study was to show the basic data to forecast the gathering effect of gathered skirt which was more aesthetical and suitable for a use in time of making pattern. To find the reasonable gathering amount by a length of gathered skirt and a fabric the methods of this study were divided on three types-five kinds of the gathering amounts three kinds of fabrics and three kinds of skirt ength-so forty five kinds of the samples were made. As the visual evaluation of the gathered skirt were practiced bgy these factors. The following are the results of this research. 1. For this research of fabrics the gathering amounts which were shown visually the most aesthetical silhouette in the same material and skirt length were decided on 1.5 times or 2.0 times. On the other side 0.5 times and 2.5 times of gathering amount were got a low estimation visually 2. Except in case the skirt length was 40cm and gathering amount were 1.0 times and 1.5 times in the same gathering amount and length of skirt it was estimated that wool fabric was most aesthetical silhouette fabric. On the other hand it was got low estimation which the cotton was not good for draping effect because it was got the lowest estimation level in all cases. 3. Considered as a whole in the same gathering amount and fabric the fabric widths for gathering which were shown the most aesthetical silhouette were estimated the length of 60cm in cotton fabric 80cm in polyester fabric and 40cm in wool fabric. Therefore as a fabric was weighty a length of a skirt was shorten so, it was estimated visually more beautiful.

The purpose of this study was to identify the reasonable gathering conditions as consider of effect of gathering and variation of silhouette made by gathering conditions. The experimental design consists of four factorial design: (1) three kinds of different weight and different thickness fabrics (2) three kinds of different stitch densities (3) five kinds of different ratio of gathers (4) three kinds of different angles. Therefore one hundred thirty five (135) samples were made. Data analysis utilize SPSS WIN 10.0 Package. The results of this study were as follows: 1. In the aspect of fabrics, it is shown the visual propriety that it is as thin as the small stitch, and as thick as the big stitch. 2. As stitch densities, it shows the different stabilized nodes. 3. In the aspect of ratio of gathers, it is shown the visual propriety that a few was small stitches, which help formations of nodes, and a lot were big stitches, which help increased the effect of gather. 4. In the aspect of angle of bias, the drape appearance was excellent as a sample of cutting by 0 angle(0$^{\circ}$) of bias. The big stitches that help formations of stabilized nodes, and a case of cutting by 45 angle(45$^{\circ}$) of bias was small stitch.

The purpose of this research is to analyze the shape of gathered skirts made by different gatherings. The shape of gathered skirts is affected by the amount of the gatherings that control fullness along a waistline seam. The gap also has an effect on the shape. We made a few experiments to make gathered skirts in different gathering conditions. The conditions include two types of ratio of gathers, which were given the total amount of gathering, and two types of spread of gathers, which were calculated for waist and hip. Experiments were conducted to figure out the dressed shape through 3-D measurement Exyma- WBS, and also to investigate the proportion, area distribution, and gap of the shape of gathered skirts on the horizontal section map with Rapid Form 2004 SP3, a software for 3-D shape analysis. As the results show, there were differences among the proportion, area distribution, and gap of the dressed shape. It showed that the shape on the horizontal section map was different because the shape between waist and hip per parts on body was not the same.

The purpose of this study was to analyze the shape of gathered skirts using a three-dimensional measurement system. And in this experiment, I try to accumulate three-dimensional data of wearing model and to figure out analyzing method made by shape of clothes. The experimental design consists of two factorial designs. I set up three different kinds of fabrics, ratio of gathers. Therefore nine samples were made. The instrument and tools for three-dimensional measurement was whole body 3D scanner. Analysis program used in experiment is RapidForm 2004 PP1 and Pattern Design 2000. Data analysis utilizes SPSS WIN 10.0 Package. T-test to effect an inspection of evidence, there was difference about measurement times. One-way ANOVA to analysis effect of gather made by gathering conditions. The following results were obtained; 1. As a result of inspecting an error several times using a three-dimension measurement system, convinced data was obtained. 2. At front, distribution of gap amount was larger than back. And as ratio of gathers increased, distribution of gap amount showed regularly. 3. After analyzing horizontal sectional figure of skirts, as a height of skirt changed from waist to the bottom of skirts, the results showed as follows. While section width, section thickness, node width, node depth increased, node count decreased. 4. With the horizontal section levels of gather skirt, the silhouette on middle hip section was similar with the silhouette of body line. And as ratio of gathers around hip section increased, nodes showed regularly. At the bottom of skirts showed different nodes by different gathering condition.

In the construction industry, IT based information system has been diversely applied to increase productivity. Although IT device such as PDA, RFID, Barcode, wireless network and web camera has been introduced to gather information in construction site, the effect of the IT device is limited, because of bringing about additional works of engineer. In this paper, we proposed a defect management system which is based on handwritten document digitalization framework for introducing applicability of new IT device, digital pen. By the proposed system, we can effectively gather and input defect information to defect management system by using digital pen and paper like conventional way. Applying the data gathering device, digital pen to defect management, it is able to increase productivity by improving work process, building up and utilizing defect information database of good quality.

Coalbed methane has a nonlinear desorption curve depending on the pressure, so an appropriate production system should be constructed considering this phenomenon. The capacity and specification of the coalbed methane gas production facility are determined by the gas flow rate and pressure in the coalbed, which is the external boundary condition of the system. Thus, it is essential to analyze these characteristics in gas production. The gas inflow equation was calculated using the reservoir flow model and utilized as the boundary condition of the whole production facility in this study. Also, to understand the effect of pressure drop on the gas flow in the production facility, the nodal analysis was performed using the flow analysis simulator of production equipment, and we determined the proper specifications and operating conditions of the production facility. This study presents a design criteria as to production and gathering system capable of effectively transporting coalbed methane.

This study was carried out to identify the effect of seed gathering time and after-ripening on Paeonia lactiflora Pall (PL) seed emergence, and to establish optimal seed gathering time and sowing time. We used two local cultivar of PL ; Punggi and Uisung. Seeds were gathered 6 times from 5th July to 25th August in 1992. The seeds of Punggi local cultivar were planted by the planting density of $10\;{\times}\;15cm$ after treatment of 7 ways ; without after-ripening, with after-ripening for 10, 20, 30 days without or with capsule. We investigated the change of 100 grains weight of PL seed by the passage of time and emergence rate after treatment. The seed weight of Punggi was heavier than that of Uisung and the seed weight was maximzed at 25th July both of the two, and then decreased by the passage of time. The seed emergence rate of Punggi gathered at 5th July was showed 7.8% and the seed emergence of Uisung was later 10 days than that of Punggi. The maximum emergence rate of two local cultivars was the highest in gathering the seeds on the 15th of August. In gathering the seeds without and with capsule, the emergence rate of seeds sowed with after-ripening was higher than that of seeds sowed immediately after gathering the seeds without after-ripening when the seeds gathered between 5th July and 5th August. In after-ripening with out and with capsule, the emergence rate of 10 days after-ripening seeds was less than that of 20 and 30 days after-ripening seeds after the seeds gathered on the 5th and 15th of July. Difference of the emergence rate of seeds by after-ripening time did not show when the seeds gathered after 25th July.

In this study, I suggest dyed-Glued laminated woods by using birch woods which are relatively cheaper than others. Since the dyed-Glued laminated woods which have the various colors to satisfy people's tastes and the dignified grains in the old woods enable us to product freely, these can provide us with stability of supply through replacing rare materials. The making wooden furniture designed with dyed-Glued laminated woods has these following characteristics. (1) This method which uses various colored woods can fulfill consumers' tastes through dyeing wooden plates, instead of using domestic woods which have limited colors-white, yellow and black. (2) Gathering wooden plates made by setting them into various frames enables us to get in large quantities of the materials with good grains, which we can only take from old woods. (3) Producing culture products using various colors and grains has enabled us to satisfy consumers and to create pro-environmental pieces. In conclusion, this study can be an alternative idea to forest resources which have been decreasing, and be an application method of using cheaper birch woods as well. Gathering and dyeing wooden plates might bring about the economic effect and be of much help to the expansion as furniture materials as well as interior ones.
