The purpose of this study is to analyze the size of ready-made clothing for elderly women and to evaluate their fit according to body type. Subjects were 33 women aged 60 and older, and they were classified by stature and drop index. The size of clothing which manufactured by four apparel brands were measured and compared with body size, and the size designation of four brands was compared. The questionnaire was carried out to subjects, and the size recognition and dissatisfaction with ready-made clothing were analyzed. The fitting test were carried out, and the subjects evaluated the fit of jackets and slacks of four brands. In the result of questionnaire, we found that subjects had little recognition about their clothing size. Subjects responded that they often felt dissatisfaction in their jacket length, sleeve length, shoulder width, bust girth, slacks, and waist girth. We found that each apparel brands had different sizing system and that even if the size designation of label was same, the clothing size was quite different. So the elderly women who didn't have so much knowledge about their own clothing size had a tendency to confuse with choosing proper clothing for themselves. In the wearer's evaluation, the significant difference in the degree of unsatisfaction were certified in several body parts according to wearer's body type. Especially, the degree of unsatisfaction in the case of subjects of having very small stature or very small hip was higher than other body types. From the result, we certified that it was necessary to consider the characteristics of each body type to increase the satisfaction of elderly women with clothing.

The purpose of this study was to develop an appropriate jacket pattern for obese women in 20s and 30s, providing a good fit and appearance. The results were as follows: among 3 kinds of patterns collected in order to develop a jacket pattern to fit the average body of an obese woman in 20s and 30s, a business-type pattern(which was comparatively evaluated as a good fit) was worn and revised so as to design a final research pattern with proper fitness and a good shape. The biggest problem of the existing pattern was may overall spares, especially many spares of bust size, waist measurement, hip circumference, all of which makes a bad appearance. Considering the results of a survey which indicates that young obese women like tight-fitting clothes, bust size was decreased from 8 cm to 6 cm, and their waist measurements were bigger compared to other age groups, so a total of 1.1 cm(with 0.3 cm in the front, back side, and 0.5 cm in the back waist) was decreased. The hip circumference was decreased by 2 cm from H/2+4 to H/2+2 cm, the quantity of front deflection was established as 1.5 cm in order to compensate for the coming off of the front side caused by the fat on the stomach.

Comparative studies on generalized binomial models (Moon, 2003; Ng, 1989; Paul, 1985; Kupper and Haseman, 1978; Griffiths, 1973) are restrictive in that the models compared are rather limited and MSE of the estimates is the only measure considered for the model adequacy. This paper is aimed to report simulation results which provide possible guidelines for selecting a proper model. We examine Pearson type of goodness-of-fit statistic to its degrees of freedom and AIC for the overall model quality. MSE and Bias of the individual estimates are also considered as the component fit measures. Performance of some models varies widely for a certain range of the parameter space while most of the models are quite competent. Our evaluation shows that the Extended Beta-Binomial model (Prentice, 1986) turns out to be particularly favorable in the point that it provides consistently excellent fit almost all over the values of the intra-class correlation coefficient and the probability of success.

In the last decade, the replacement of old PFM restorations has been a common dental procedure, especially on the anterior regions. Gingiva conditions in most re-treatment cases are not healthy with the old restorations due to ill-fitting margin, improper tooth reduction and poor oral hygiene. Practitioners must carefully evaluate and manage periabutmental gingiva for final restorations. The role of provisional restoration became a major clinical concern at this point. Well-fabricated provisional restorations with precise-fit margin and proper anatomy are critical for achieving good gingival health. Thus, the key of success in replacing old PFM crown depends on the proper tissue management by precise provisional restorations.

Computer simulation for the predictions of casting defects is very important to produce high quality castings with less cost. Complicate shaped Al solenoid housing part was selected to be cold chamber die cast and a numerical simulation technique was applied for the optimization of the chill vent position and gating. A first design led to insufficient central flow. This flow left the last filled areas falling into the inner portion of the part. And last filled area did not fit the chill vent position. So these resulted in a high possibility of air entrapment in the casting and the design was not proper for the part. The design was improved by using a proper gating system, a more chill vent and proper overflow positions. New design provided a homogenous mold filling pattern and the last filled areas that being located at the overflow and chill vent. Casting plan which produce good quality solenoid housing part was established by using the computer simulation.

Particle size distributions in 10 nm magnetite ferrofluids are analyzed based on both dc and ac magnetic measurements. Modified log-normal distributions are used for fitting the experimental results, which allows for a proper account of the narrow distributions. The calculated average particle sizes are in good agreement with the TEM results. However the ac method gives a much narrower distribution width than that of the dc magnetization curve fit. The proposed measurements combined with the analysis methods are useful for the characterization of ferrofluids being considered for biomedical applications.

This study aims to suggest the proper ease for slim-fit jackets according to the number of buttons from a one-button jacket to four-button jackets for men in their 30's. The researchers carried out both an appearance evaluation and movement functionality evaluation. The results are as follows: When conducting the appearance evaluations, meaningful differences were found. The one-button jacket showed high scores for the 7.5 cm ease. The two-button jacket and the three-button jacket showed high scores for the 10.5 cm ease. The four-button jacket showed a high score for the 13.5 cm ease. Next, the results of the movement functionality evaluation showed the same trend; as the ease was increased from 7.5 cm to 13.5 cm, the scores increased. This is because if the garments offer more ease, this gives room for actions. Additionally, it showed that if there were fewer jacket buttons, then the results showed a high score. The researchers believe that if the number of jacket buttons is lower, then the area of the V-zone increases, so that there is more room for movement. The study suggests a proper chest ease of 7.5 cm for the one-button jacket, 10.5 cm for the two-button jacket and three-button jacket, and 13.5 cm for the four-button jacket, respectively.

Objectives: This study compares the differences of fit factors before and after training on the N95 mask. The results will be utilized to suggest the need of providing effective training on respirator use. Methods: A total of 49 study subjects were tested, comprised of nurses from a general hospital and undergraduate nursing students from a medical school. Anthropometric measurements of face length and face width were compared with the NIOSH(National Institute for Occupational Safety and Health) panel. Fit factors(FF) were measured with TSI Portacount Pro+8038 before and after on-site training regarding the proper use of respirators. The FF pass/fail criterion was set at 100. Results: Two subjects(4.1 %) passed the fit test before training on use of the N95. However, 36(73.5%) of the 49 passed the test after training. Overall the FF(GM(GSD)) was 13.4(3.2) before training, but improved to 106.6(2.1) after training, which was statistically significant. These findings suggest the efficacy of educational intervention, and the performance of the direct on-site training proved to be better than that of the traditional educational methods. Conclusions: This study showed the effect of on-site training of the N95 respirator among health care workers(HCW). Therefore, providing effective training on the use of N95 for HCWs before their work assignments will greatly reduce exposure to harmful agents. It is recommended that fit testing be mandated to check for adequate protection being provided by the given respirators.
