The purpose of this study is to suggest a designing method with excellent body suitability by analyzing clothingwearing porosity, comparing and analyzing patterns, and evaluating outer appearances by designing a prototype of study applied with design measurements for categories that have influence on the outer appearance of clothing through diverse research methods, by comparing and analyzing bunka and new bunka style basic pattern, which are proportional basic patterns most frequently used in schools for educational use to design bodice pattern for elderly women in their late 60s. As for the process of this study, the first stage selected study subjects, measured bodies. The second stage compared patterns of bunka and new bunka style basic pattern and evaluated outer appearances that deduced important pattern designing categories to design upper-torso bodice pattern of elderly women. The results of this study are as following ; As a result of comparing and analyzing bunka and new bunka style basic pattern, overall evaluation of outer appearance was excellent for new bunka style basic pattern, and bunka basic pattern received better reviews for the width and depth of front neck. In terms of waist circumference, waist front length, bust point location and bust point-bust point, bunka and new bunka style basic patterns showed a significant difference. new bunka style basic pattern had 4.5cm larger front armhole depth than bunka basic pattern, so it was evaluated to have more appropriate front armhole length, bust point location, and bust point-bust point. Through observation for primary excellent categories and precedent studies, 7 categories of front neck width, front neck depth, front interscye, back neck width, back neck depth, back interscye, and back armhole depth were deduced to have relations to the extra room around arm holes and waist that affect pattern designing method and porosity and evaluations of outer appearance.

This study evaluates the fit preference of the tailored jacket according to body types for 20's adult women through a comparison of real and virtual fit. A five point fit evaluation scale utilizing a wearer acceptability scale by Shen and Huck was used to evaluate the degree of the preference of real and virtual fit. This scale contained 23 items in three categories: front fit, back fit, and side fit. For each item, 5 responses from 'too tight' fit (1 point) to 'too loose' fit (5 point) were possible. The middle position for each fit criterion indicated a 'good' fit (3 point). The data were analyzed with a t-test using statistical program SPSS 17.0. According to the results, there were no significant differences ($p{\leq}.05$) between the real and virtual fit preference in total measurement items such as front collar, lapel and roll line, front shoulder slope, front armhole, front waist, abdomen, sideseam, hemline, front silhouette, side shoulder, side armhole, side sleeve width, side hip, side silhouette, back collar stand, upper back, back armhole, back waist, back hip, back silhouette except front bust, side waist, and back center back. The factor that caused a difference in the fit preference between the real and virtual fit evaluation was a specific body type such as Body Type A that indicated a small bust circumference and a big hip circumference.

The detailed structure of a tidal front and its ebb-to flood variation in the main tidal channel of the Kyunggi Bay in the mid-west coast of Korea were investigated by analyzing CTD data and drifter trajectories collected in late July 1999. A typical tidal front was formed in water about 60 m deep at the mouth of the channel. Isotherms and isohalines in the upper layer above the seasonal pycnocline in the offshore stratified zone inclined upward to the sea surface to form a surface front, while those in the lower layer declined to the bottom front. The location of the front is consistent with $100 S^3/cm^2$ of the mixing index H/U defined by Simpson and Hunter (1974), where H is the water depth and U is the amplitude of tidal current. The potential energy anomaly in the frontal zone varied at an ebb-to flood tidal cycle, showing a minimum at slack water after ebb but a maximum at slack water after flood. This ebb-to flood variation in potential energy anomaly is not accounted for by the mixing index. We conclude that on- and offshore displacement of the water column by tidal advection is responsible for the ebb-to-flood variation in the frontal zone.

In this study, experiments on the SWCC were performed in order to find out the characteristics of unsaturated soil and to analyze the stability of unsaturated weathered slopes with rainfall-induced wetting. Several soil types classified by mixture portion of clay (CH) in the weathered soil (SW) were used in experimental tests. To achieve the SWCC, the filter paper method was used on SW with varying clay contents. A tensiometer test was used for measuring wetting front suction of the soils in a laboratory with varying relative densities. Based on the experimental results, it is shown that the wetting front suction increases as clay contest of mixture soil increases : in particular, the wetting front suction increases sharply as the clay contents increase. It is also found that wetting front suction affects the initial wetting band depth and stability of the slope.

The purpose of this study is to understand spatio-temporal changes of active fungal biomass and water in Tricholoma matsutake soil colonies during the mushroom fruiting season. The active fungal biomass was estimated by analyzing ergosterol content at four different points within four replicated locations in a single circular T. matsutake colony at Ssanggok valley in the Sogri Mt. National Park in Korea during 2003 to 2005. The four points were the ahead of the colony, the front edge of the colony and 20 cm and 40 cm back from the front edge of the colony. Ergosterol content was 0.0 to 0.7 ${\mu}g$ per gram dried soil at the ahead, 2.5 to 4.8 ${\mu}g$ at the front edge, 0.5 to 1.8 ${\mu}g$ at the 20 cm back and 0.3 to 0.8 ${\mu}g$ at the 40 cm back. The ergosterol content was very high at the front edge where the T. matsutake hyphae were most active. However, ergosterol content did not significantly change during the fruiting season, September to October. Soil water contents were lower at the front edge and 20 cm back from the front edge of the colony than at the ahead and 40 cm back during the fruiting season. Soil water content ranged from 12 to 19% at the ahead, 10 to 11% at the edge, 9 to 11% at the 20 cm back and 11 to 15% at the 40 cm back. Our results suggest that the active front edge of the T. matsutake soil colony could be managed in terms of water relation and T. matsutake ectomycorrhizal root development.

The purpose of this study is to research on changes of body surface according to golf movements in designs of golf slacks pattern and reflect it to designs of golf slacks pattern to enhance adaptability. For the first stage of this study, length of body surface was analyzed by using 3D body shape. In second stage, analysis of wearing test of golf slacks is performed to extract major pattern design factor of golf slacks and then research patterns were designed. In third stage, 4 differently designed 1st, 2nd slacks were used for analysis of 3D Clothing air volume. The results of this research is as follow. The variation rate of body surface length according to golf swing posture resulted the longest on back swing posture and follow through posture. Waist circumference-omphalion, thigh and ankle circumference increased more than 10% of body surface during golf swing. Front waist circumference-omphalion, right waist to hip length, left waist to hip length and right back center length were decreased more than 10%. As a result of analysis on measurements of 1st slacks pattern design, waist front center getting in values, waist front center going down value, front hip width, and front crotch extension had similar industrial pattern design. Back center line angle, back crotch extension, and knee center point~back waist center point had significant differences. The designs and ease proposed for golf slacks pattern in this study are waist circumference 75.5 cm(1.8 cm, 2.38%), hip circumference 95 cm(2 cm, 2.11%), crotch length(front: -0.8 cm, -1.25%; rear: -1.8 cm, -2.83%), slacks length 96c m, gradient of C.B.L $10^{\circ}$, crotch extension (back 9.2~10.4 cm, front 3.2 cm).

Experiments were carried out to investigate the ballistic performance of fiber reinforced plastic(FRP)-steel plates completely penetrated by hemispherical-nosed projectiles at sub-ordnance velocities greater than their ballistic limits. The FRP-steel plate consists of a front FRP laminate and a steel backing plate. Failure mechanisms and impact energy absorptions of FRP-steel plates were analyzed and compared with FRP laminates and single steel plates. The effects of relative thickness, manufacturing method and fabric type of front composite armors as well as the joining style between front composite armors and steel backing plates on the total perforation resistance of FRP-steel plates were explored. It is found that in the case of FRP-steel plates completely penetrated by hemispherical-nosed projectiles at low velocities, the failure modes of front composite armors are slightly changed while for steel backing plates, the dominate failure modes are greatly changed due to the influence of front composite armors. The relative thickness and fabric type of front composite armors as well as the joining style of FRP-steel plates have large effects whereas the manufacturing method of front composite armors has slight effect on the total perforation resistance of FRP-steel plates.

The structure of the south Korean coastal front, their fluctuation, the properties and the probable effects of the front on the mackerel fishery are discussed based on the data of 26 cruises in 1967-1969 in the southern waters of Korea. In the south Korean coastal water the annual variations of the properties shows the greatest magnitude among the other water masses in the north of East China Sea. The salinity profile provides a fairly accurate description of the interface between the two kinds of water and agree with the temperature structure in winter. The temperature front does not always coincide with the salinity front in summer, while the former corresponds to the later in winter. The sharpest and most stable front between the Tsushima Warm Current and the south Koren coastal water was found in autumn and winter. In autumn 1969, the most successful catches of mackerel was recorded in the south Korean front of great borizontal gradients of properties(temperature 5.0$^{\circ}C$/10miles, salinity 1.2 /10miles) in the east of Cheju Is. If future investigation finds the peculiar oceanographical conditions like that shown in summer, 1969, the conditions of frontal layer in coming autumn will be estimated and finally the success of the mackerel fishery will be predictable from preseason information on temperature and salinity structure in the southern waters of Korea.

This study analyzed 2D bodice sloper changes according to combinations of the lateral neck and shoulder points of a 3D mannequin's shoulder lines. The relationship between the 3D shape and 2D pattern was analyzed. The shoulder line was set to a default of 1cm in front of or behind the lateral neck point, 1cm in front or behind the lateral shoulder point and 1cm vertically above the lateral neck or shoulder point. When the lateral neck point was moved backward, the front neck depth, front and back shoulder height, and shoulder length in the 3D shape increased, whereas the back neck's depth and width decreased. In the 2D pattern, the back shoulder height decreased. As the lateral shoulder point moved backward, all items of the 3D shape showed little change. However, the front shoulder height for the 2D pattern decreased. Consequently, the back shoulder height increased, and the lateral neck point was raised vertically by 1cm. Meanwhile, only the back neck depth and shoulder length decreased while all other items increased; however, in the 2D pattern, the front neck width and shoulder line showed no notable change. The shoulder point was raised vertically by 1cm, and the front and back shoulder heights of the 3D shape and 2D pattern were decreased.
