The operation of electric automatic windows is used in harsh environments, and the energy density decreases as charging and discharging are repeated, and as soundness deteriorates due to damage to the internal separator, the vehicle's mileage decreases and the charging speed slows down, so about 5 to 10 Batteries that have been used for about a year are classified as waste batteries, and for this reason, as the risk of battery fire and explosion increases, it is essential to diagnose batteries and estimate SOH. Estimation of current battery SOH is a very important content, and it evaluates the state of the battery by measuring the time, temperature, and voltage required while repeatedly charging and discharging the battery. There are disadvantages. In this paper, measurement of discharge capacity (C-rate) using a waste battery of a Tesla car in order to predict SOH estimation of a lithium-ion battery. A Support Vector Machine (SVM), one of the machine models, was applied using the data measured from the waste battery.

This study features an analysis of the socio-economic factors of ten cities on the Honam-line that affect the number of train passengers. The 3 main factors based on the principal component analysis were the population, the distance between two regions, and the area size of each region while the number of automobiles has been conventionally used instead of the area size of each region. A formula to predict the train passengers by the regression analysis was developed and showed a good agreement to the number of real passengers. When Honam highspeed railway is opened, the traveling time between two regions as well as the area size of each regions should be more precisely considered.

This study investigated the best condition when mixed sand with a river and crushed sand was used though the experiment for the properties of the concrete corresponding to the control of fine aggregate ratio to apply the mixed sand and properties of the fine aggregate at the ready-mixed concrete factory on Yeongnam and Honam. The physical properties of Yeongnam and Honam is satisfied with KS F 2526 and KS F 2527 except fineness modulus and passing amount of 8mm sieve. And, the mixed sand above two types which were incongruent to use individually was being used at each factory, and it was managed in accordance with KS. The flowabillity of the mixture proportion of concrete which was estimated by method of unit volume weight according to the fine aggregate ratio at each factory on Yeongnam and Honam was higher than existing mixture proportion. It was analyzed that the residual water due to decline of the surface area caused by reducing fine aggregate ratio was increased relatively. Accordingly, it was considered that the effect on the economic mixture proportion and improvement of durability might be possible.

PURPOSE: To investigate the validity of a smartphone application for post-stroke daily living activity management based on an evaluation by users and experts. METHODS: The study design adhered to the analysis, design, development, implementation, and evaluation ADDIE (Analysis-Design-Development-Implement-Evaluation) model. We downloaded the application onto the smartphones of 33 users and 30 experts, taught them how to use it, and asked them to use the application for four weeks. The users' daily lives before and after using the application were compared based on the K-MBI (Korean Version of Modified Barthel Index) to evaluate the usability of the application. For the expert group, we investigated the content validity and reliability of the application and evaluated the usability of the application. Data were analyzed using the SPSS 21.0 software. Users' general characteristics and experts' evaluation scores were analyzed using descriptive statistics. Content validity was tested using the content validity index (CVI), and reliability was tested with Cronbach's alpha. Users' K-MBI scores before and after using the application were compared with the paired sample t-test. RESULTS: Users gave an average rating of 2.93 out of 4 for the application for managing the daily lives of stroke patients, while experts gave an average score of 3.14. With regard to the K-MBI scores, only the dressing score improved significantly (p<.005) after using the application, and scores for other categories slightly improved but not to significant levels. CONCLUSION: The results of this study suggest that the STROKECARE application is usable and could help stroke patients manage their daily lives.

KORAIL has improved profitability through abolition of nonprofitable route and withdraw rolling stocks, operated at that route. as a part of that process, most sections of commuters' train are gone. presently, gyeongui-line and gyeongwon-line's commuter's trains are operated. Despite the abolition, there are demands for commuters' train. so, nonprofitable route operation policies are needed to meet the demands and connect seamlessly to KTX. In this study, we consider the overall operation policies and problems of commuters' train in the past. and then, we analyze foreign nonprofitable route, connected with high speed train, operation policies and search for the development suggestions for applying to the nonprofitable route between Iksan - jeonju section at Honam and joenra line.

Needs for a new technologies of infrastructure systems arose, following the development of next generation EMU(Electric Multiple Unit) train with maximum speed over 400km/h. For high-speed operation tests of the new EMU, a high-speed railway infrastructure test-bed was constructed in a 28km long section of the Honam High-speed Railway. Diverse sensors and monitoring system was installed for continuous monitoring of the railway. Due to such effort, further demands and needs of the integrated monitoring system was derived in a more comprehensive and long-term perspective.

This study investigated correlations among interpersonal problems, body dissatisfaction, and makeup behavior among college students. The results provide basic data which are helpful for students to build healthy interpersonal relationships and suggest a direction for beauty care behavior. This study derived the following results: A close correlation was identified between international problems and body dissatisfaction and body dissatisfaction and makeup behavior. In other words, college students suffering from interpersonal problems also experienced body dissatisfaction. In addition, those with body dissatisfaction have made efforts to overcome such problem through makeup behavior. This could be viewed as meaning that the greater the body dissatisfaction, the more active college students are in makeup management behavior, and the intention to resolve their physical dissatisfaction through makeup management behavior was included. Therefore, society or colleges need to recognize the necessity of counseling or treatment programs for college students suffering from interpersonal problems or body dissatisfaction and help them enter into society through diverse programs. Additionally, appearance management programs, such as the aforementioned makeup behavior, that can make them satisfied with their body should be developed. Ultimately, diverse suggestions that can help students improve their self-esteem and interpersonal relationships and enhance sociality through such social efforts should be formulated.

This study aimed to unveil the causality between the emotional marketing of aesthetic salons and brand awareness/relationship continuity in Chinese female consumers. For data collection, a self-administered questionnaire survey was conducted among adult women in their 20s or older in Liaoning Province, China, from February 2 to 18, 2023, using WeChat. From a total of 431distributed questionnaires, 393 copies were collected. Then, 369 copies, excluding 24 poorly answered ones, were used for the final analysis. The collected data were analyzed using SPSS 25.0 and the summary of the results of the study is as follows. First, in emotional marketing, sight, smell, hearing, and taste had a positive(+) influence on both cognitive and affective experiences. Second, in emotional marketing, sight, smell, and taste displayed a positive(+) effect on relationship continuity. Third, in brand awareness, both cognitive and affective experiences showed a positive(+) effect on relationship continuity. Collectively, this means that the higher the cognitive and emotional marketing of brand awareness, the higher the relationship continuity persistence. This study confirmed the causality among the emotional marketing of aesthetic salons, brand awareness, and relationship continuity; sight and taste were key factors that influenced brand awareness and relationship continuity.
