To develop smart sportswear capable of measuring biometric data, we created a close-fitting pattern using two- and three-dimensional (2D and 3D, respectively) methods. After 3D virtual fitting, the tightness of each pattern was evaluated using image processing of contact points, mesh deviation, and cross-sectional shapes. In contact-point analysis, the 3D pattern showed high rates of contact with the body (84.6% and 93.1% for shirts and pants, respectively). Compared with the 2D pattern, the 3D pattern demonstrated closer contact at the lower chest, upper arm, and thigh regions, where electrocardiography and electromyography were primarily carried out. The overall average gap was also lower in the 3D pattern (5.27 and 4.66 mm in shirts and pants, respectively). In the underbust, waist, thigh circumference, and mid-thigh circumference, the cross-section distance between clothing and body was showed a statistically significant difference and evenly distributed in the 3D pattern, exhibiting more closeness. The tightness and fit of the 3D smart sportswear sensor pattern were successfully evaluated. We believe that this study is critical, as it facilitates the comparison of different patterns through visualization and digitization through 3D virtual fitting.

Corona on polymer materials causes deterioration by the combined action of the discharge striking the surface and the action of certain chemical compounds that are formed by the discharges. In the design and manufacture of polymer insulators must be sufficiently large to avoid corona discharges, otherwise a shielding or corona ring (grading ring) needs to be installed on the insulator. To conduct this purpose, many researchers have investigated end-fitting of polymer insulator by voltage distribution simulation and electrical test. Grading rings are used to improve the performance of the insulator in multiple ways. They can reduce corona and associated audible noise and radio influence and television interference. The factors determining the uses of a grading ring are line voltage, geometry and dimensions of end fittings, geometry and dimensions of line hardware, and environmental conditions. In this paper, electrical property of polymer insulator with end-fitting design have been investigated by electrical field analysis, various end-fitting design, tracking wheel test, corona inception voltage and extinction voltage. Electrical field analysis is conducted by FEM program and various end-fitting is designed through this result. Designed end-fittings are manufactured and their performance is conducted by electrical performance test.

The purpose of this study is to find the Dart Manipulation with good fitting and evaluate the aesthetics of Dart Manipulation that is used in the designs of the original tops for women in their 30's. Subsequently, it suggests dart manipulation with good body fitting and physical fitness when designing original tops. The findings of this study are as follows. First, in the fitting of Dart Manipulation for different body types, cross direction Dart Manipulation received good marks in the Square Body Type while mixed direction and diagonal direction Dart Manipulation received high evaluation in the Standard Body Type. Also, for the Reverse Triangle Body Type, mixed direction Dart Manipulation received high marks. Since there are only small changes in fitting for the Square Body Type, the position of Dart Manipulation should be determined in regards to the aesthetic view as well as the fitting of the Standard Body Type and Reverse Triangle Body Type. Second, in the fitness of Dart Manipulation for different body types, an approach from the aesthetic view should be considered for Square Body Types because of the differences in fitness according to the position of dart manipulation. The fitness should be considered when positioning Dart Manipulation for the Standard Body Type and Reverse Triangle Body Type because of these differences. Third, for the greater variance of drop for these different body types, the change of the amount of dart received lower evaluation in fitting since the amount of dart increased when the dart was located higher than B.P. The number of dart should likely increase when gathering or tucking is necessary when there is an excessive amount of dart in Dart Manipulation for the different body types. Fourth, as for the changes of wrinkles in accordance with the body type, wrinkles were likely to be formed at the breast or neck area when there was a larger difference in drop. To prevent such problems, one more dart should be made on the wrinkle. In conclusion, the study suggests designing the original top with a better look and comfort by setting the balance between aesthetics and fitting in the design stage.

Since the recorded information used for operation of a catchment modelling system contain errors that influence the calibration of catchment modelling system control parameter values, the accurate estimation of these parameters is difficult. Despite these influences, existing traditional calibration approaches focus only on achieving the best "curve fitting" between simulated and recorded data, and not on generic evaluation of control parameter values. This paper introduces an Early Stopping Technique which is aimed at avoiding the procedure of curve-fitting through monitoring improvements in the objective function used for assessing the optimal parameter set. Application of this approach to the calibration of SWMM (Storm Water Management Model) on the Centennial Park catchment in Sydney, Australia is outlined. outlined.

청각학적 재활은 청력손실 배경 정보 획득, 청각학적 평가, 보청기 전기음향특성 분석, 음향 이득 결정만으로도 충분히 만족스러운 서비스를 제공할 수 있다. 그러나 청력은 나빠질 수 있고, 보청기는 출력음압이 낮아지거나 고장이 발생할 수도 있다. 따라서 청력손실의 조기 발견과 정기적인 추적 관찰은 매우 중요하다. 이 연구는 정상적인 추적에도 불구하고 보청기 조절 실수가 확인된 증례를 통해 효과적인 청각언어재활 방향을 고민하는데 목적이 있다.

This study aims to verify the psychological evaluation that consumers undergo when accepting virtual fitting services while shopping online. The Theory of Interactive Media Effects (TIME) was applied to determine the impact of the perceived affordance of media on consumer response through immersion. An online survey was conducted targeting female consumers in their 20s and 30s, and 271 responses were collected and used for empirical analysis. The results of the analysis showed that interactivity and immediacy had a positive effect on telepresence. Telepresence, in turn, affected perceived usefulness and enjoyment, which then significantly affected purchase intention. In addition, some paths confirmed the moderating effect of consumer innovativeness. In consumers with high innovativeness, interactivity was found to have a greater influence on telepresence and perceived usefulness had a more significant influence on purchase intention than in consumers with low innovativeness. Conversely, in consumers with low innovativeness, perceived enjoyment was found to have a greater influence on purchase intention than in consumers with high innovativeness. The significance of this study is that it expands research on customer perception of virtual fitting services within online shopping platforms.

The purpose of this study is to evaluate on the fitting with human resource practice and strategic on 6 public hospital in the point of resource based view. At the result of this study, public strategy is not much fitted into HRM(human resource management) system, but it shows positive result of the fitting with efficiency strategy and HRM system. These results were associated with the integration of G Medical Center. Generally 6 public hospitals of the HRM system and the strategy had not been linked. They also did not achieve a great outcome. We suggest that the manager in charge of each hospital make strategies of the hospital, and then evaluates about fitting with HRM system. We hope, hereafter, it applied the analysis methods that evaluates it with financing result and individual non-financial result all together.
