Ergonomic techniques have been required to analyze the effectiveness of functional clothing design improvement in a systematic and analytic manner. The goals of the present study are to: (1) comprehensively and analytically examine the effectiveness of clothing improvement by using the relationship analysis between clothing design components (D) and ergonomic evaluation measures (E) and (2) prove the usefulness of cost-effectiveness analysis for clothing design optimization. The cost effectiveness analysis is comprised of the preliminary evaluation based on expertise and the in-depth evaluation where the D-E relationship analysis is applied. As a result of the cost effectiveness analysis applied to flame-proof clothing, an optimal design was identified by analyzing costs and qualitative/quantitative effects. In the preliminary evaluation, the expected effectiveness of each design alternative on wear efficiency and wear comfort was estimated. In the in-depth evaluation, however, the effectiveness of each design alternative was analyzed by quantitative evaluation in a wearing test using a questionnaire prepared based on the D-E relationship analysis. It was concluded that the D-E relationship analysis and the cost-effectiveness analysis are useful for comprehensive evaluation and optimization of functional clothing design.

The goal of this study is to present efficient measures to improve the quality of medical education through using a developed and applied continuous quality improvement (CQI) model suitable for medical education. To achieve this purpose, we developed a theoretical CQI model through a review of the literature according to the design-based research method. Through repetitive productive cyclical processes and professional reviews, we finally deduced an appropriate CQI model for medical education. The most important results of this study are as follows: First, the CQI model for medical education is defined as a quality management system with a cyclical course of planning, implementation, evaluation, and improvement of medical education. Second, the CQI model for medical education is composed of quality management activities of educational design, work, and evaluation. In addition, each activity has the implementation strategies of planning, doing, checking, and improving based on the PDCA model (Plan-Do-Check-Act model). Third, the CQI model for medical school education is composed of committees related to medical education doing improvement activities, as well as planning, implementing and evaluating it with CQI. As a result, we can improve teaching by using the CQI model for medical education. It is more meaningful because this gives us organized and practical measures of quality management and improvement in medical education as well as in the educational process.

A comprehensive study was conducted to design economical foundations for a number of buildings on soft cohesive soil in the southern coastal regions of Iran. Both static and seismic loads were considered in the design process. Cyclic experiments indicated that the cohesive soil of the area has potential for softening. Consequently, the major challenge in the design stages was relatively high dimensions of settlement, under both static and seismic loadings. Routine soil-improvement methods were too costly for the vast area of the project. After detailed numerical modeling of different scenarios, we concluded that, in following a performance-based design approach and applying a special time schedule of construction, most of the settlement would dissipate during the construction of the buildings. Making the foundation as rigid as possible was another way to prevent any probable differential settlement. Stiff subgrade of stone and lime mortar under the grid foundation and a reinforced concrete slab on the foundation were considered as appropriate to this effect. In favor of an economical design, in case the design earthquake strikes the site, the estimations indicate no collapse of the buildings even if considerable uniform settlements may occur. This is a considerable alternative design to costly soil-improvement methods.
