Background : The design type of mobile marketing advertisement has the function of attracting consumers’ attention but has become a factor in avoiding advertisements. Through this study, we aim to provide basic data that could increase the efficiency of mobile advertising by investigating and analyzing the types of mobile advertising designs preferred by consumers. Methods : After setting the preferences of six mobile advertising design formats as independent variables, advertisement acceptability and purchase intention were composed of dependent variables based on the Ryu (2022) model. Next, data was collected by conducting a survey on mobile advertising design preferences from October 24 to October 31, 2022. For the analysis tool, one-way distribution analysis was performed using IBM SPSS statistics 26.0, then post-evaluated using Scheffes method. Results : Video, delivery, search, and interaction advertisement formats were found to be more significant in terms of average advertisement acceptability and purchase intention than banner and social media advertisements. Also, there were significant results from advertising design types that broke away from existing mobile advertising designs, consisting of new techniques and contents to attract consumers’ attention. Conclusions : This study examines the types of mobile marketing advertising designs preferred by consumers in relation to advertising acceptability and purchase intention. In mobile advertising, continuous messages and advertisements that engage consumers will be able to effectively deliver products. We hope through this study that the research material will contribute to the development of the fast-changing industry of mobile advertisement design.

Recently, high-performance and high-fluidity concrete have been studied and developed because high-rised build is constructed. high-performance and self-consolidating concrete is demanded high strength as low w/cm and fluidity as adding superplasticizer. However, these superplasticizer are changed early-age property such as bleeding, segregation and late setting time etc. This study persents the setting time of fluidity mortars evaluated using the measurement of eletrical resistivity. 7th Samples prepared mortars which were adding polycarboxylate type superplasticizer(Ester) or poly naphthalene sulfonate(PNS) and measured the electrical resisitivity during 24 h. As a results, mortars which added superplasticizers were late rising time which is setting time in measurement of electrical resistivity. However, degree of hardening of PNS mortar were higher than Ester mortar.

본 연구에서는 다양한 발사체 추진기관 공급계 배관 자재 중 STS 300 계열의 금속보다 강도가 높고 용접성이 우수할 것이라고 판단되는 21-6-9 합금소재를 이용하여 산화제 주배관의 시편을 제작 하였다. 제작된 시편은 내압 시험을 수행하여 요구되는 내압 강도를 유지할 수 있는지를 확인하였다. This article deals with the manufacturing and performance evaluation on the specimen pipes which have large size diameter and thin thickness. This specimen is for LOX main pipe of KSLV-II propulsion feeding system. The material of specimen is alloy 21-6-9. Alloy 21-6-9 has higher strength and better weldability rather than STS-300 class pipes. We found that the specimen using alloy 21-6-9 satisfied the requirement by pressurization tests.

EPS is power steering system, which uses motor actuator to assist the Steering torque. EPS has many benefits such as fuel efficient, simple component structure, easy to assemble and control flexibility over HPS (Hydraulic Power Steering). So, there is a tendency to substitute HPS with EPS system in many vehicles in terms of advancement and other factors by which EPS is better than HPS. In spite of many benefits of EPS, there is a disadvantage of undesired action from the EPS system, which can be very harmful to a driver because it can cause no assistance or unsteer able of steering wheel. So, during the designing and development of EPS system, it is needed to take some important parameters into consideration like robustness and reliability. To retain robust and reliable EPS system, various conditions have to be tested, not only from functionality point of view but from the safety point of view also. System fault is a very important factor to consider the safety. In order to deliver a reliable and safe EPS system, many fault scenarios should be prepared and tested by both software algorithms and hardware components. Those faults can be physical and electronic faults. This study develops an EPS HIL simulator which can perform fault injection test based on test automation environment.

Recently, high-performance and high-fluidity concrete have been studied and developed because high-rised build is constructed. An early-age properties of these concretes have been studied and developed bacause of comparing existed concrete. This study proposed non-destructive method as electrical resistivity measurement, which evaluates setting time of cement-based materials. An assessment of the effect on the setting time was studied on the addition of a superplasticizer to delay the setting time and the curing temperature to promote the setting time. 6<sup>th</sup> of samples prepared mortar according to adding superplasticizer(PNS) or curing temperature and measured the electrical resistivity during 24 h. As the results, mortars which curing higher temperature were promoted rising time which is setting time in the electrical resistivity, also mortars which adding superplasticizer were retard rising time.

ACC Stop & Go is a full range adaptive cruise control system, which operates from 0㎞/h to 180㎞/h speed range. ACC Stop & Go system uses 77㎓ radar sensor to detect forward objects. Radar sensor detects the distance and the relative velocity of forward objects, and it decides target acceleration or deceleration values. The goal of this study is to develop hardware-in-loop simulator for applications of ACC Stop & Go system such as control algorithm development, fail management development and system verification and validation. The developed HIL simulator consists of a real time operating system, a sensor emulator, a test bench, and operation software. Especially this simulator needs not only a vehicle model, but a radar sensor model also. The radar sensor model enables the detection of forward objects, so that the distance and the relative velocity from forward object can be calculated in mathematical method. The test bench of simulator uses real vehicle’s driver seat and 3 dimensional graphic animation program, so it makes more realistic environment to testers. To verify this simulator’s performance, simulation results are compared with real field test results.
