This study presents quantitative evaluation standards for the shape fitness test, conducted in the process of the slacks fit test. This study aims to quantify appearance sensory test of slacks for the objectification of qualitative evaluation methods in existing shape fitness tests. The subjects were women of standard body type between the ages of 18 and 24. Slacks differing in their ease in waist girth, hip girth, crotch length and knee length were designed to test their shape fitness. The gap volume distribution between the body and slack, angle of the baseline by body part, and ratio of total thickness from the sideline using 3D human body scan data (which reflect the results of the appearance sensory test) were presented as quantitative evaluation standards. There were less wrinkles in the wrinkle/overstretch and ease categories of the appearance sensory test; in addition, ease was adequate and small enough to comfortably perform basic human activities in the standing upright posture. The gap volume distribution analysis between body and slacks showed that curves increased in the slacks surface along with an increase of ease in slacks and suggested that wrinkles also increased. In the baseline's horizontal categories in terms of a $0^{\circ}$ horizontal angle, the range of angles were evaluated as adequate by the clothing expert group. The total thickness ratio of 0.5:0.5 divides into the sideline from the baseline.

This study was attempted to investigate the possibilities of fitness evaluation of virtual model using 3D clothes modeling software. For the purpose, two one-piece dresses were made with two kinds of patterns using Qualoth program, and then each dress was fitted to a real model and a virtual model, and the results were compared and discussed. The result of this study was as follows. First, the fitness evaluation of real model showed a significant difference only at a little difference in figures (1-2.5cm) of the pattern, while any significant difference in appearance was not found in case of a virtual model fitted a dress made out of a pattern with the same difference in figures. Second, items to evaluate a difference in patterns using 3D clothes modeling software were shoulder line, the distance between shoulder points, armhole line, ease of armscye depth, and overall appearance. Because all the items fall under design lines which make up outer lines of a cloth, it can be said that the Qualoth program is good for representing design, rather than exposing a small difference in patterns.

In this study, fitness tests for slacks were divided into shape fitness test and motion fitness test, and the fitness test conditions for slacks were designed as the first step for standardization of measuring scales. Shape fitness test consisted of analyzing the parameters of appearance sensory tests as described in preceding studies, performing a simulated appearance sensory test, collecting and considering apparel experts' opinions about the test parameters, and establishing test conditions in terms of test regions, descriptions and faces. For the regions of the abdomen, hip, crotch, thighs, and knees, the parameter of unnecessary wrinkle/stretch was observed from the anterior and posterior body, and then evaluated; for waist, hip, crotch, knee and hem circumference, the parameters of ease and horizontality were observed from the anterior body and posterior body followed by evaluation; and, at the levels of waist, hip, crotch, knee and hem circumference, the division of the lateral line were observed from the lateral body followed by evaluation. Motion fitness test was composed of reviewing and analyzing comparatively the methods of motion fitness tests as mentioned in preceding studies, and establishing test conditions in terms of test motions and test regions. For each of the waist, abdomen, hip, crotch, and knees, wear sensation was tested in the positions as follows: upright standing, moderate walking, chairsitting, bending forward to the maximum, and kneeling down, provided that as the measured points of garment pressure, anterior waist, abdominal protrusion, buttock protrusion, crotch, and midpatella were set and tested.

The objective of this study is to propose a method by which movement fitness can be evaluated using a three-dimensional virtual garment simulation program. To this end, five types of jean pants for men were evaluated on the program by setting the avatars to make particular movements to examine the level of pressure on each body part. To verify whether the clothing pressure measurement produces valid and reliable results, virtual garment simulation program was utilized. The results indicated that there were significant differences in the levels of pressure on body parts depending on the type of test garment and motion. In addition, the clothing pressure measurement results were in line with the appearance evaluation results suggested by a previous study. Based on this set of results, the nomological validity of the clothing pressure measurement program used in this study was verified. Moreover, we employed an appearance evaluation along with the clothing pressure measurement to verify the reliability of the program; there was a high correlation between clothing pressure measurements and appearance evaluation measurements, indicating that measuring clothing pressures may well compensate for the limitations of appearance evaluation. We expect the results of this study to make valuable contributions in facilitating the digitalization of the fashion industry. Furthermore, this study also is significant in that it has suggested 3D virtual fitting programs as a solution to the long-criticized problem related to the evaluation of movement fitness in existing virtual garment simulation programs.

The purpose of this study was to investigate the fitness using the draft method to develop moderate-stretch knit block pattern for young women in Korea. The subjects were three women within the range of the ages from 18 to 24 showing the average body figures. In this study, 4 different patterns were drafted for the moderate stretch knitted fabrics, that were categorised into two different types. The first type of these was made up for kilted fabrics and the other was initially drafted for woven fabrics and altered for knitted materials afterward. The major findings derived from this investigation were as follows; 1. According to each sensory evaluation for the appearance test on fitness, knit block patterns A and D were the better than the rest of them. 2. Knit block patterns A and D with higher evaluation scores were drafted with body size measurements except the waist line, whereas patterns B and C with relatively lower scores were produced including the smaller ease amounts than the woven block pattern. 3. To see the results of the functional test based on the designed ten motions for this experiment, knit block patterns A and B were concluded as better than the rest of them. In addition, concerning the arm liking motions, pattern B was scored as the best among the developed patterns.

Background: Recently, three-dimensional (3D) printing has been hailed as a disruptive technology in dentistry. Among 3D printers, a digital light processing (DLP) 3D printer has certain advantages, such as high precision and relatively low cost. Therefore, the latest trend in resin crown manufacturing is the use of DLP 3D printers. However, studies on the internal fitness of such resin crowns are insufficient. The recently introduced 3D evaluation method makes it possible to visually evaluate the error of the desired area. The purpose of this study is to evaluate the internal fitness of resin crowns fabricated a by DLP 3D printer using the 3D evaluation method. Methods: The working model was chosen as the maxillary molar implant model. A total of 20 resin crowns were manufactured by dividing these into two groups. One group was manufactured by subtractive manufacturing system (PMMA), while the other group was manufactured by additive manufacturing system, which uses a DLP 3D printer. Resin crowns data were measured using a 3D evaluation program. Internal fitness was calculated by root mean square (RMS). The RMS was calculated using the Geomagic Verify software, and the mean and standard deviation (SD) were measured. For statistical analysis, IBM SPSS Statistics for Windows ver. 22.0 (IBM Corp., USA) was used. Then, independent t-test was performed between the two groups. Results: The mean±SD of the RMS were 41.51±1.51 and 43.09±2.32 for PMMA and DLP, respectively. There was no statistically significant difference between PMMA and DLP. Conclusion: Evaluation of internal fitness of the resin crown made using a DLP 3D printer and subtractive manufacturing system showed no statistically significant differences, and clinically acceptable results were obtained.

Modern technology has lessened the physical demand of every activities. Thus, physical inactivity has led to a rise in ‘Hypokinetic diseases’. The prefix, hypo, means lack of and kinetic refers to movement. Individuals who do not exercise regularly are at greater risk of developing hypokinetic diseases such as coronary heart disease, hypertension, hyperlipidemia, obesity, musculoskeletal disease. Systematic exercise program defenses development of hypokinetic diseases. Exercise program bases on basic physical fitness test. The physical fitness evaluation is used to degree of Wellness of the individuals. It includes the evaluation of Health-Related Physical Fitness -musclular strength, muscular endurance, flexibility, cardiorespiratory endurance, body composition - and skill or sports related fitness -agility, balance, coordination, reaction time, speed. In present study, the authors investigated health-related physical fitness test result and questionnaire for 133 male and 71 female from Jannuary 16 to March 15, 1997. The purpose of this study is to observe relationship health related physical fitness and self-perceived health status. The results are as follows. 1. There were statistically significant differences in BMI, grip strength, back strength, muscular endurance, cardiorespiratory endurance, and flexibility between male and female subjects. Flexibility is higher in female than male subject, but Others are higher in male than female subjects. 2. There were statistically significant differences in grip strength, muscular endurance between 30s, 40s, and 50s group In both gender subjects, and In cardiorespiratoryendurance between the groups especially in Female subjects. 3. For male subjects, flexibilitywas measured lower in group who classified low level in self-perceived health status than group of others. Also, for female, subjects, Muscular endurance ＆ flexibility were measured. 4. It was shown that grip strength, back strength, and muscular endurance were significantly lower in group who have chronic diseases than normal group for Male subjects.

In this paper. we suggest a vector fitness strategy for obstacle avoidance of autonomous mobile robot with genetic algorithm. Ordinary genetic algorithms provide not such a viable solution for autonomous running in a variant environment. because of the difficulty in fitness evaluation in real time. We show that the suggested method is efficient for the problem of autonomous mobile robot. Its control function evolves to adapt the varying environment. The experiment is done using the real mobile robot 'Khepera' with which we use a tournament genetic algorithm model with the Vectored Fitness Genetic Strategy.
