To determine the effect of base curve and diameter of soft contact lenses on the fitting under the various corneal curvature, the model eyes which was made of either stainless steel or ordinary wood, were used as the substitutes for human eyes. The evaluations of fit of the soft contact lenses on both wood model eyes and human eyes were found to be very similar to each other. All the contact lenses except very thin ones became flat after fit on the stainless steel model eyes because the model eye could not preserve enough moisture to hold the edge of contact lenses on the steel ball's surface. The relationships between the base curves of contact lenses and radii of cornea for the optimum (normal) fit were measured as follows : corneal curvature (C.C)<7.6 mm : base curve(B.C) 8.4 mm, C.C 7.6~7.8 mm : B.C 8.4~8.5 mm. C.C 7.8~8.1 mm : B.C 8.6 mm. It is concluded that larger base curve is required for the eyes which have abnormal bulge on its cornea. It is found that very thin soft contact lenses can be easily twisted or folded regardless of moisture content when they were fit on the relatively dry eyes(corneas).

The Face Stimulus Assessment is an efficient projective drawing test developed by Betts. This paper categorizes scales which Betts suggested into the following five groups: accuracy of painting, color fit, perception of shape, precision of drawing, and space usage. In this paper, a computer algorithm which objectively evaluates these five scales is suggested. The proposed algorithm defines the areas of the lip, eyes, hair, etc. which take on significant roles in the evaluation of the FSA and based on these factors, it calculates the grade of each scale through the main color and color ratio. The consistency of evaluations between the computer algorithm and the art therapist is measured by the Quadratic Weighted Kappa. By providing objectivity and consistency, the computer algorithm is expected to solve the problem of uncertainty found in art therapists' evaluations of projective drawing tests caused by their subjective judgment, experience, and intuition.

The present research aimed at researching the relationships among place attachment, residential evaluations and satisfaction in a medium-sized post-communist Romanian city. Studies on post-communist cities are scarce and this research tried to fill that gap. This research is part of a government project that intended to significantly reform three medium-sized cities in the Western part of Romania and transform the urban space. Since the three of them are relatively small-sized and close spatially, the project intends to undertake massive reforms of the communications and services of the three cities. In this article, we report findings on the city of Hunedoara. A representative random sample was selected, and a total of 384 people were interviewed, with an overall reliability of the sample of 95%. The instruments used to gather the data were the Neighbourhood Perceived Environmental Quality Scale and a composite measure of place attachment was also included. The structure of each scale was checked using exploratory factor analysis. We tested alternative causal models using structural equations modelling. Our model showed a good fit to the data and explains satisfaction in the city adequately. Results show that satisfaction is directly predicted by the general evaluation of the city and by residential privacy. Residential noise and place attachment influence satisfaction indirectly. The results are discussed and some policy recommendations are formulated.

Objective: Considering the importance of dairy farming and the negative effects of heat stress, more tolerant genotypes need to be identified. The objective of this study was to investigate the effect of heat stress via temperature-humidity index (THI) and diurnal temperature variation (DTV) in the genetic evaluations for daily milk yield of Holstein dairy cattle, using random regression models. Methods: The data comprised 94,549 test-day records of 11,294 first parity Holstein cows from Brazil, collected from 1997 to 2013, and bioclimatic data (THI and DTV) from 18 weather stations. Least square linear regression models were used to determine the THI and DTV thresholds for milk yield losses caused by heat stress. In addition to the standard model (SM, without bioclimatic variables), THI and DTV were combined in various ways and tested for different days, totaling 41 models. Results: The THI and DTV thresholds for milk yield losses was THI = 74 (-0.106 kg/d/THI) and DTV = 13 (-0.045 kg/d/DTV). The model that included THI and DTV as fixed effects, considering the two-day average, presented better fit (-2logL, Akaike information criterion, and Bayesian information criterion). The estimated breeding values (EBVs) and the reliabilities of the EBVs improved when using this model. Conclusion: Sires are re-ranking when heat stress indicators are included in the model. Genetic evaluation using the mean of two days of THI and DTV as fixed effect, improved EBVs and EBVs reliability.

In this research, we examine whether and why temporal distance influences evaluations of two different types of brand extensions: concept-based extensions, defined as extensions primarily based on the importance or relevance of brand concepts to extension products; and similarity-based extensions, defined as extensions primarily based on the amount of feature similarity at the product-category level. In Study 1, we test the hypothesis that concept-based extensions are evaluated more favorably when they are framed to launch in the distant rather than in the near future, whereas similaritybased extensions are evaluated more favorably when they are framed to launch in the near rather than in the distant future. In Study 2, we confirm that this time-dependent differential evaluation is driven by the difference in construal level between the bases of the two types of extensions - i.e., brand-concept consistency and product-category feature similarity. As such, we find that conceptbased extensions are evaluated more favorably under the abstract than concrete mindset, whereas similarity-based extensions are evaluated more favorably under the concrete than abstract mindset. In Study 3, we extend to the case for a broad brand (i.e., brands that market products across multiple categories), finding that making accessible a specific product category of a broad parent brand influences evaluations of near-future, but not distant-future, brand extensions. Combined together, our findings suggest that temporal distance influences brand extension evaluation through its effect on the importance placed on brand concepts and feature similarity. That is, consumers rely on different bases to evaluate brand extensions, depending on their perception of when the extensions take place and on under what mindset they are placed. This research makes theoretical contributions to the brand extension research by identifying one important determinant to brand extension evaluation and also uncovering its underlying dynamics. It also contributes to expanding the scope of the construal level theory by putting forth a novel interpretation of two bases of perceived fit in terms of construal level. Marketers who are about to launch and advertise brand extensions may benefit by considering temporal-distance information in determining what content to deliver about extensions in their communication efforts. Conceptual relation of a parent brand to extensions needs to be emphasized in the distant future, whereas feature similarity should be highlighted in the near future.

In order to examine the characteristics of brassiere products for the 1924 generation brands on the market and grasp problems, we selected three 'comparative brassieres', each one from among the 1924 underwear brands with the highest recognition and sales profit, and then designed a 'sample brassiere' pattern(75A) with a similar shape to the comparative brassieres. We set up the "New Cup Grading Rule" with a view of reflecting the wearing effect that was varied according to cup sizes, graded the sizes of 75AA and 75B with this method, and made the sample brassieres in three sizes. We conducted the wearing evaluation and body measurements of 9 subjects after analyzing the patterns and characteristics of the sample brassieres and three comparative brassieres. As a result of the wearing evaluation, the sample and comparative brassiere 2, the dimensions and shapes were appropriate for the 1924 generation consumers and expressed an overall natural silhouette, showed satisfactory results in the entire evaluation questions. On the other hand, the comparative brassiere 1 and 3 that tended toward making a big change in the physical characteristics got unsatisfactory evaluations in the dimensions of the cups, clothing pressure, and bust silhouette. As a result of observing the variation in body dimensions by body measurements when nude and when wearing each brassiere and then summing it up with the score of the wearing evaluation, it was proven that too much change in body shape can create a negative image by upsetting the balance of the whole silhouette. Therefore, it is desirable to develop brassiere products with proper dimensions and clothing pressure that can make a physical change that harmonizes the overall bust silhouette and the position and shape of the breasts.

To develop baseball catcher leg guards, 3-dimensional (3D) methodologies, which are 3D human body data, reverse engineering, modeling, and printing, optimized guard design for representative positions. Optimization was based on analysis of 3D body surface data and subjective evaluation using 3D printing products. Reverse engineering was used for analysis and modeling based on data in three postures: standing, $90^{\circ}$ knee flexion, and $120^{\circ}$ knee flexion. During knee flexion, vertical skin length increased, with the thigh and knee larger in anterior area compared to the horizontal dimension. Moreover, $120^{\circ}$ knee flexion posture had a high radius of curvature in knee movement. Therefore, guard designs were based on increasing rates of skin deformation and numerical values of radius of curvature. Guards were designed with 3-part zoning at the thigh, knee, and shin. Guards 1 and 2 had thigh and knee boundaries allowing vertical skin length deformation because the shape of thigh and knee significantly affects to its performance. Guard 2 was designed with a narrower thigh and wider knee area than guard 1. The guards were manufactured as full-scale products on a 3D printer. Both guards fit better in sitting than standing position, and guard 2 received better evaluations than guard 1. Additional modifications were made and an optimized version (guard 3) was tested. Guard 3 showed the best fit. A design approach based on 3D data effectively determines best fitting leg guards, and 3D printing technology can customize guard design through immediate feedback from a customer.

Sanitary pads are used with for the sanitization of menstruation bleeding. In this research, twenty medium size disposable sanitary pads were selected from domestic and international brands in order to analyze their shape and size. Additionally, 6 sanitary pads were selected among the 20, and user experience evaluations were completed. The analysis on the shape of the 20 sanitary pads showed that straight-shape pads existed more than curved-shape pads. The means of total pad length, wing length, wing width, front pad width, back pad width, front pad length, and back pad length were 24.5 cm, 8.8 cm, 3.0 cm, 10.0 cm, 10.2 cm, 11.6 cm, and 13.0 cm, respectively. All selected pads were medium size; however, detailed sizes varied between brands. Eighty-one women participated on user experience evaluation. Participants felt that brand F was the longest and brand D the shortest. The results matched with the results on actual pad length measurement. Participants evaluated the fit of brand E most positively and fit of brand A most negatively. The current study provides valuable information for developing disposable sanitary pads.

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.
