With the technology of our time growing sophisticated everyday, softwares advance rapidly in accordance. Reflecting this trend, researches on Usability of S/W GUI(Graphical User Interface) is actively taking place. However, despite the active researches on such topic, Usability study of S/W GUI for weapon system remains insufficient. For such reason, this paper intends to focus on drawing evaluation factors as well as priority of design factors for Usability of S/W GUI for weapon system. For an accurate and reliable result, Usability evaluation attributes & design factors were assessed by professionals. Moreover, by incorporating AHP(Analytical Hierarchy Process) and Matrix analysis, each evaluation attributes' level of importance and relation between design factors & usability attributes were assessed to draw final design priority. As a result, the importance of Informativity, Accessibility, and Visibility were derived as 0.127, 0.121, 0.108, and selected to be the foremost priority for evaluating. This research could be utilized as foundation for usability evaluation of S/W GUI on weapon system.

In this paper, the optimum design of tire sidewall contour consisted of double plies for improving automobile maneuverability and tire durability is considered and a GUI program is developed for the purpose of the practical design. Each improvement of maneuverability and durability depends on the cord tension and strain energy distribution of tire sidewall. Satisfing trade-off method, which requires the judgment of aspiration levels, is used for the multi-objective optimization problem. Also, this paper presents the application to the practical sidewall contour design with the GUI program developed using visual Fortran.

The need for customized products has also been increasing as more active consumers consume according to their values in recent years. Accordingly, fashion customizing web is becoming popular, but because custom freedom is low, we want to increase custom freedom by applying knitwear. To this end, a theoretical review was conducted through prior research and literature research on customization, knit design, and GUI, and based on this, a case analysis was conducted focusing on knit-making programs and fashion customizing web. Knit designs have more considerations than other fashion design process, resulting in more UIs, so users should use visual elements that are easily recognizable. Therefore, a draft assessment item was derived based on the preceding survey and three Delphi surveys were conducted on experts based on the draft. Each item was modified and deleted during the Delphi research process to produce the Custom Knitware Web GUI Design Guide. Through this study, we were able to identify the need for intuitive understanding and application of knit custom functions in GUI design of custom knitwear web. Through this research, it is expected that this data will be used to improve the usability of custom knitwear websites and to refer to knit design fields that utilize knit machines.

Pilot Aptitude Research Equipment (PARE) is a simulator developed to measure or research pilot aptitude and train for student pilots. Design of an ergonomic PARE operation console is required to operate the equipment effectively. This study carried out five steps : (S1) operator questionnaire survey, (S2) anthropometric design formula development, (S3) usability evaluation, (S4) improvement design, and (S5) validation considering both Physical User Interface (PUI) and Graphic User Interface (GUI) of PARE operation console. The operator questionnaire surveyed needs for each PUI and GUI part of the console from two PARE actual operators. In terms of PUI, the anthropometric design formula was developed by using design variables, body dimensions, target population characteristics, and reference posture related to the PARE console. In terms of GUI, the usability evaluation was conducted by three usability testing experts with a 7-point scale (1 : very low, 4 : neutral, 7 : very high) on GUI of the PARE operation console by seven usability criteria. The improved PARE operation console was designed to reflect the optimal values of design variables calculated from design formula, the results from usability testing, and the operator's needs. The improvement effect was observed by 20 people who had experience with the PARE operation console. As a result of the validation, monitor visibility and cockpit visibility for the improved PUI design and visibility and efficiency for the improved GUI design were significantly increased by more than 90% respectively. The improved design of the PARE operation console in this study can contribute to enhance operation performance of the PARE.

In this paper, an approximate optimization program based on GUI(graphic user interface) environment is developed. This program is coded by using Fortran and Visual basic. Fortran is used to Progress approximate optimization process. Visual basic is used to make user environment for user to use conveniently. Inside of this program, it uses two independent programs. One is commercial program, ANSYS, and the other is optimization program, PLBA(Pshenichny-Lim-Belegundu Arora). The former is used to obtain approximate equation of stress and displacement of a structure. The latter is used to solve approximate optimization. This algorithm uses second-order information of a function and active set strategy. This program is connecting ANSYS and PLBA. And it progress the process repeatedly until it obtain optimum value. As a method of approximate optimization, sequential design domain(SDD) is introduced. SDD starts with a certain range which is offseted from midpoint of an initial design domain and then SDD of the next step is determined by optimal point of a prior step.

With technological development of product designs, products of various concepts have been developed and products by customized design concepts have been actively launched. For successful development, it is necessary to convey the target concept to the product development process exactly in order to create the targeting design. The study found the design concept of mobile phones with a boom box through emotional verbal expression, and defined the concept target by using visual images in accordance with the relative target with a view to looking for the design concept suitable to product development target. Regarding the visual image, the test for coordination among participants was conducted to select the image on which the interest groups participating in the development reach an agreement. As a result of the test, it aimed to propose the method to select concepts and images for rational choice by means of clustering algorithms. This method is considered to contribute to building the design concept and actualizing GUI design.

As the cconvenience economy of food culture becomes more widespread and the consumption trends for easy and convenient meals grew, every food company is making their various efforts to provide better service. Along with this change, various methods have been allowed for quick and easy ordering. Especially, the introduction of kiosk systems with various merits such as reduction of queues for cashes, saving labor costs, and smoothness of business processes have been actively growing recently. If kiosk system provides not only order but also systematic contents and interface design considering differentiated identity from other companies, brand image enhancement and customer service strategy would be available as well. A kiosk GUI design for effective interactions that provides more usability and satisfaction to users by analyzing the structure and contents of kiosks in fast food stores and GUI designs and investigating usage patterns and design preferences of kiosks through user surveys.

As information becomes more sophisticated with the advancing technology of our times, the usability of software is considered an important factor. However, the research on usability of weapons system software graphical user interfaces (GUIs) remains insufficient. For this reason, this paper focuses on developing checklists for the usability of GUIs in weapons systems. In the first step, design principles are collected from various design guidelines on usability and from career soldiers. In the second step, a survey is conducted for factor analysis, and in the third step, factor analysis is conducted on 12 principles, with two principles excluded, as a result, due to less correlation with weapons system usability. In Step 4, the weights for design characteristics and design principles are derived using AHP. In the final step, the checklists are developed by mapping the GUI design factors and from the results of factor analysis. This research could be utilized as a foundation for usability evaluation of GUIs in weapons systems.
