This study evaluates the fitness of brassieres through size measurement, comparative pattern analysis, cross section map analysis, 3-D shape analysis number, and fitness evaluation with a focus on domestic and overseas brands. Experimental brassieres were selected as mold brassieres of 3/4 cup in 75A size that is considered a popular design. Brands of selected brassiere were 2 domestic brands (A, B), 1 licensed brand (C), and 2 overseas brands (D, E). Subjects were 8 women in their early 20's. Data were analyzed by descriptive statistics, analysis of variance, reliability analysis, and factor analysis. The results were as follows; the size and pattern of brassieres showed a difference by each brand even though brassieres are the same design. In the wearing effect of brassieres, overseas brand brassieres played a major role in the breast-up effect, but they were not appropriate for the somatotype of Korean women. Domestic brand brassieres showed the volume-up effect, that was confirmed by the increasing bust circumference, bust depth when subjects wore it. In addition, the licensed brand brassieres showed the correction effect of body shape. Therefore, when purchasing a brassiere, the most important condition is to consider the individual characteristics of the somatotype. The results of factor analysis through a functional evaluation show that wearing satisfaction, size satisfaction, and the position of the bust point were important factors for fitness satisfaction and purchase.

The purpose of this study was to develope a pattern drafting method for various somatotype which contribute largely to increase the fitness and comfort of garments. This study had 8 subjects who were college girls who had prominent somatic characteristics. The study was carried out by the following procedures. 1. The 8 subjects who had prominent somatic characteristics were cheesed by photograph- ing. The somatotypes of 8 subjects were classified into Standard somatotype, Turning over somatotype, Bending somatotype and Turning over-Bending somatotype. 2. Under the criterion of the body surface development, the comparative investigation on the pattern and the sensory evaluation were accomplished in the flat pattern method and the draping pattern method. 3. The body surface development of them were made by the draping pattern method. 4. In the result of the comparative investigation and the sensory evaluation, it was found that the flat pattern had better appearance and comfort than the draping pattern, and the draping pattern included more somatic characteristics than the flat pattern. 5. On the basis of those result, the pattern drafting method according to the somatotype was indicated and it was examinated by the clothing experiment. 6. The sensory evaluation for appearance and comfort was applied to evaluate the new basic pattern for four somatotype by comparing it with the conventional basic pattern (Rim, won ja' 5). The result of the sensory evaluation, it was found that the new basic pattern was more suitable for each somatotype than the conventional basic pattern.

The purpose of this study is to perform comparative economic evaluation for the systems of ground source heat pump (GSHP) and district heating and cooling (DHC) by focusing on the analysis of operation case of GSHP. The adapted research object is a public office building located in Seoul. The capacity of ground source pump is about 3,900 kW. Ground heat exchanger is closed loop type. The analysis period for life cycle cost is 30 years. Economic evaluation is assessed from the viewpoints of the following four parts: initial cost, energy cost, maintenance and replacement cost, and environment cost. The total life cycle cost of GSHP is approximately 8,447 million won. The cost of the DHC System is approximately 3,793 million won. The cost of the DHC is approximately 46% lower than GSHP system under the condition of current rate for GSHP and DHC.

The object of this paper is to acquire the data related to insulation evaluation of hybrid vehicle traction motors. We made a comparative analysis on Insulation Resistance (IR), Dielectric Absorption Ratio (DAR), and Polarization Index (PI) of the motor stators. The experiment was carried out according to IEEE Std. 43 and IEC 60085-1 for insulation resistance test standard of rotating machinery. Test voltage of 500 V was applied between a phase and the enclosure. The IR and the DAR of used motors were lower than those of new ones. The DAR and the PI were $0.92{\sim}1.02$ and $0.74{\sim}1.1$, respectively and the result did not meet the recommendation basis 2 for insulation level H. From the experimental results, we could prepare parameters and basis for insulation evaluation of the traction motor stator by the comparative analysis of short-time insulation resistance changes, DAR and PI.

To investigate the comparative susceptibility of E. coli and S. aureus strains isolated from Korean foods to sanitizer/disinfectants, the bactericidal efficacies of sodium hypochlorite and benzalkonium chloride were assessed by quantitative suspension tests in both 'clean' and 'dirty' conditions, respectively. The sanitizers/disinfectants achieved over 5-log reduction in viable counts of all strains at the tolerance exemption concentration, except in the case of S. aureus exposure to sodium hypochlorite under dirty condition. There were no significant differences in the susceptibility of antibiotic-resistrant and antibiotic-sensitive isolated strains to the sanitizers/disinfectants (p>0.05).

Slope was necessarily formed by development of hilly district for human living. At present slope is distributed about sixteen thousand in state road and expressway. Nevertheless, rule of preservation management for slope is overlapping or diffuse. In this study it analyze condition evaluation for slope.
