This study was conducted to reproduce the four-piece bodice pattern of a ladies' costume of the 1890's for Korean women in their twenties with a standard body type and average size. Eighteen four-piece bodice patterns of the ladies' costume of the 1890's were collected and drawn to actual size. The front width of the bodice was wider than the back width. The front bust line of the bodice was wider than the sum of the back bust line, the side back bust line and the under-arm gore bust line. The front waist line of the bodice was wider than the sum of the back waist line, the side back waist line and the under-arm gore waist line. The angles of the two waist darts of the bodice were very big but the legs of the dart were too short. The center front line of the bodice was oblique and curved. The angle of the back shoulder line of the bodice was bigger than the angle of front shoulder line. The shoulder seam line of the bodice was not placed on the top of the shoulder but behind the shoulder. The pattern characteristics of the bodice created a woman's silhouette that emphasized the volume of the bust, a chicken breast and a slim waist. The study pattern which had the characteristics of the four-piece bodice of the 1890's was designed like for Korean women in their twenties who have a standard body type and an average size through modifications based on the evaluation of two dressing occasions. The study pattern was evaluated to have the silhouette of the 1890's and to fit Korean women.

The objective of the study was to provide fun-damental data on somatotype for elderly women by classifying the somatotype and analyzing the characteristics of their somatotype. The subjects were 368 women ages of 60∼84, they were measured direct anthropometry. In or-der to find out differences among the age groups, the 368 subjects were grouped into two age groups(Group 1 aged 60 to 69, Group 2 ; aged 70 to 84) Data were analyzed using Factor analysis, Cluster analysis, Duncan test and Analysis of variance. The results of this study were as follows. 1. The characteristics of Elderly women's somatotype were bending of the upper-torso, fat-ness of the waist and abdomen, drooping of the bust and shoulder and hip. In addition, height, girth, depth and width items were decreased in their sizes respectively. 2. Through the factor analysis, we extracted 5 factors from anthropometric measurements. Factor components were obesity, height, girth of the leg and arm, length of the upper-torso except the center front length, the center front length, we categorized by 4 clusters using 5 factor scores. And after the cluster analysis using 5 factor scores, 4 clusters were categorized. The characteristics of clusters were as follows. Type 1 was characterized by short, obesity type, and droopy bust. Type 2 was characterized by short and slender type, dropped bust, and bending somatotype from the lateral view. Type 3 was characterized by middle sized and straight somatotype from the lateral view. Type 4 was characterized by tall and obese type from the lateral view.

In South Korea, U-type girder development was attempted as a means to increase the length of I-type girder, but due to the large self-weight according to the post-tension method, the application of rail bridges of 30m or less is typical. There are not many examples of application of pre-tension type girder. This study does not limit the post-tension method, but applies the pre-tension method to induce a reduction in self-weight and materials used due to the reduction of the cross-section. In addition, we intend to apply the on-site pre-tensioning method using the internal reaction arm of the U-type girder. The prestressed concrete U-type girder bridge is composed of a concrete deck slab and a composite section. Compared to the PSC I-type, which is an open cross-section because the cross section is closed, structural performance such as resistance and rigidity is improved, the safety of construction is increased during the manufacturing and erection stage, and the height ratio is reduced due to the reduction of its own weight. Therefore, it is possible to secure the aesthetic scenery and economical of the bridge. As a result, it is expected that efficient construction will be possible with high-quality factory-manufactured members and cast-in-place members. In this paper, the introduction of the pre-tension method on-site and the analytical performance verification of the anchoring block for tension are included.

Purpose: We wanted to improve the setup reproducibility of breast cancer patients when utilizing a commercially available breast board for radiation therapy. The breast board was modified by using a new head rest and 2 types of board fixation devices. Materials and Methods: A conventional head/neck rest was modified to be positioned in various slots of the breast board, and it was fabricated 1 cm thinner to provide more comfort to a patient when the patient's neck was rotated. This rest improves the uncertainty of the daily setup. Also, the sagging problems at the left and right sides became negligible with the two types of board fixation devices: (1) the stair type, and (2) the arm type. The first device consists of an upper/lower holder with 4 stair-types of grooves and 4 rectangular Inserts. In order to cover the whole range of vertical setup of the breast board, 4 rectangular inserts were needed, and each covered 10 steps. The arm-type fixation device was also fabricated and attached to the breast board, It had two aluminum bars that were fixed by utilizing a lock-type of screw. These devises were evaluated with two volunteers in order to prove the effectiveness of the improved setup accuracy. Results; The developed cranio-caudal fixation device demonstrated that it could reduce the cranio-caudal error by nearly $55\%$ compared to the old device. As for left-and-right inclination, the stair-type and arm-type fixation devices can reduce the relative inclination by nearly $80\%$ and $90\%$, respectively, compared to the breast board without the fixation device. Conclusion: It was verified that the developed devices were effective for positioning the patients and for avoiding inclination of the breast board.

The present study was designed to compare the nutritional status of hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients. Subjects were 58 HD patients (male/female = 29/29) and 33 CAPD patients (male/female = 23/10) undergoing dialysis treatment in Artificial Kidney Unit of Chonbuk National University Hospital. For nutritional assessment, %IBW (ideal body weight), %TSF (tricep skin fold), %MAC (mid arm circumference), %MAMC (mid arm muscle circumference), serum albumin, serum transferrin, TLC (total lymphocyte count), SGA (subjective global assessment) and estimated energy and protein intakes by 1-month food frequency method were used. Between HD and CAPD group, mean age (50 $\pm$ 12 vs. 52 $\pm$ 12 yr), dialysis durations (37 $\pm$ 36 vs. 30 $\pm$ 26 mon), dietary energy intakes (28.3 $\pm$ 9.0 vs. 28.8 $\pm$ 8.6 kcal/kg/day), dietary protein intakes (1.1 $\pm$ 0.4 vs. 1.2 $\pm$ 0.3 g/kg/day) and incidence of co-morbid conditions (69.0% vs. 69.7%) were not significantly different. Data by using SGA showed a higher incidence of malnutrition in CAPD patients (45.6%) than in HD patients (36.2%). %IBW (p < 0.001), %TSF (p < 0.001) and %MAC (p < 0.001) were higher in CAPD patients than were in HD patients. But serum albumin (p < 0.001) and transferrin (p < 0.001) were significantly lower in CAPD patients than were in HD patients. A higher incidence of malnutrition was shown in CAPD Patients than in HD Patients due to different dialysis type. A significant finding was that CAPD showed protein deficient malnutrition and HD did calorie deficient malnutrition. It suggests that an adequate dietary intake considering dialysis type prevents a prevalence of malnutrition.
