Applying Bayesian optimal design principles is not easy when a prior distribution is not certain. We present a optimal design criterion which possibly yield a reasonably good design and also robust with respect to misspecification of the prior distributions. The criterion is applied to the problem of estimating the turning point of a quadratic regression. Exact mathematical results are presented under certain conditions on prior distributions. Computational results are given for some cases not satisfying our conditions.

This study is for analyzing relationship between clothing and shoes design in the 20th century fashion through studying changes of fashion style. At the beginning of the 20th century, the length of skirts became shorten, so that shoes can be shown. For the result of that. shoes has been developed rapidly in its shape, color, material and ornament with having relations with clothes. The 1st World War made fashion to change into economical style. According to that, shoes also changed with regarding its activities and economical efficiency. In the middle of the 20th century. according to the development of mass media. the stars fashion influenced on the trends of clothes and shoes. As young generation. who leads fashion trends, prefer easy and active clothes, shoes also changed into easy style, sneakers were worn widely and platform sole was applied into various shoes. As a result of this study, shoes design was dynamically changed according to fashion style. The study on its functional efficiency is actively studied now however. the study of shoes design is not. When regarding shoes were always worn with clothes, it is impossible to think shoes and clothes are two things. and also I hope the study on relations between clothes and shoes can be more active and consistently implemented.

We suggest the development of a mobile muscular savings account application as a more effective and consistent strategy to avoid sarcopenia, one of the elderly diseases, based on the researcher's experience conducting a handwritten 'muscle saving account' in the S city of the metropolitan area. The analysis of currently existent healthcare-related applications shows that muscle strength improvement and maintenance applications are needed to improve easy use and access without burden for elderly users because there are many functions, and it can be difficult for the elderly to use the application. A survey of participants who used handwritten 'muscle savings accounts' was conducted before the design development to measure user satisfaction. Based on this, the suggested application's design is similar to the handwritten type, functionalities are modified for easy usage by the elderly, and information is intuitively comprehended and presented properly using color contrast and Sans serif font. We plan to conduct a survey of the elderly who did not participate in the project as part of follow-up research, and afterward continue the research on the development of customized applications optimized for the prevention of sarcopenia in the elderly for muscle strength improvement and maintenance based on the results.

The purpose of this study was to analyze middle students' carbonated beverages selection and consumption behaviors depending on their food-related lifestyle. Data was collected from 307 middle students in Incheon region through a self-administered questionnaire. According to the results of the factor analysis, food-related lifestyle showed that the average is more than 3.0, 0.800 in Cronbach alpha coefficient. There were significant differences in carbonated beverages preference according to health seeking, easy seeking, popularity seeking, and safety seeking type (p<0.05). Also easy seeking and popularity seeking type lifestyle showed significant differences in the reason to drink carbonated drinks (p<0.05), especially school canteen amenities tended to pursue the highest fashion. A significant significance positive result of the consumption of carbonated beverages (p<0.01) was shown for the easy seeking type. A significant positive result of the consumption of carbonated beverages (p<0.01) was shown for the taste seeking and safety seeking type. Analysis of the relationship between carbonated beverage consumption, and form factor showed a high correlation coefficient of 0.617 and with brand design, while the taste and the price were (p<0.05) 0.446, and 0.437 in order to design and calories, respectively.

본 연구는 소비자가 판촉을 인식할 때 판촉이 제시하는 혜택을 소비자가 지불해야 하는 현금손실을 감소시켜주는 것으로 보는지 혹은 정상적인 거래이후에 추가적으로 받게 되는 이득으로 인식하는지에 따라서 판매촉진에 대한 가치평가가 달라지게 된다는 것을 검증하기 위한 것이다. 구체적으로 판촉도구의 특성차원 세 가지, 혜택의 실현시점이 즉각적일수록, 판촉물의 현가계산의 용이할수록, 판촉물과 본래제품이 유사시점에 구매할수록 소비자가 지불해야 하는 현금손실을 줄여주는 것으로 인식할 것이며, 이와 같이 감소된 손실로 인식되는 판촉이 추가된 이득으로 인식되는 판촉보다 판촉의 가치평가가 더욱 클 것으로 가정하였다. 대학생을 대상으로 집단간/내 설계를 통하여 자료를 얻고 ANOVA와 구조방정식 모형으로 가설을 검증하였다. 결과적으로 현가계산과 유사시점구매는 검증되었으나 혜택실현시점가설은 통계적으로 유의하지 않았다. 감소된 손실은 추가된 이득보다 판촉가치평가에 더 효과적이었고, 나아가서 구매의도를 더 높혀주었다.

When a manual transmission equipped car stops on an incline where the nose of the car is higher than the rear, hill-start control or hill-holder could prevent the vehicle from rolling backward as the car moves forward. The easy-hill assist valve consists of a check valve and a needle type ON/OFF solenoid valve connected in parallel; it is a hydraulic actuator that can maintain brake pressure using an electrical signal from the ECU. As the EHA valve is a safety-related component of the brake system, high reliability as well as superior dynamic performance is required for it to be applied in commercial vehicles. This paper presents the design of the EHA valve as a piece of equipment that can simulate the brake actuation pressure with a pressurizing piston. Following specific test standards, the experimental results validate the implemented functions of the test equipment, proving the test stand to be effective for the performance and endurance of the EHA valve.

Arduino is used in various places such as education, experimentation, and industry. Due to the easy accessibility of Arduino, it is often used by non-majors, and it is also used in media art and toy programs. Although Arduino is relatively easy to use compared to other devices, it is not easy to control various IoT components at the same time. Some tasks run independently of other tasks, while others run dependently. In this paper, I proposed the Arduino Task Framework to efficiently execute many tasks in these various situations. The design framework of this paper is largely composed of two types: synchronous execution and asynchronous execution. These two execution methods can be combined to create several independent and dependent execution routines. Asynchronous tasks are independently executed tasks and are managed by AsyncTaskGroup, while synchronous tasks are dependently executed tasks and are managed by SyncTaskGroup. AsyncTaskGroup instance and SyncTaskGroup instance are instances of the same Task and can be used in combination with another task. The Arduino framework proposed in this paper simplifies the program structure and can easily compose various tasks.
