This study analyzes the differences in perception of cosmetic quality (safety, stability, functionality, usability) and satisfaction according to consumer characteristics, targeting 317 men and women from their 18 to 50s who use cosmetics in Seoul and Gyeonggi Province, and the differences in effect of cosmetic quality perception on satisfaction according to side effects experience was analyzed. Among the cosmetic quality factors, the usability was satisfied, but the perception of safety, stability, and functionality was low, so overall quality improvement was necessary. In particular, the quality perception and satisfaction by men and 40s was low, so a customized solution was needed for this. In the order of usability and functionality, to both those experiencing or not side effect, had a significant positive effect on the satisfaction level, and the improvement of usability and functional awareness was the main factor that increased satisfaction. Improving product quality and supplementing factors that positively influence consumer perception are thought to be of great help in improving quality perception and satisfaction.

Eye tracking is one of the NUI technologies, and it finds out where the user is gazing. This technology allows users to input text or control GUI, and further analyzes the user's gaze so that it can be applied to commercial advertisements. In the eye tracking system, the allowable range varies depending on the quality of the image and the degree of freedom of movement of the user. Therefore, there is a need for a method of estimating the accuracy of eye tracking in advance. The accuracy of eye tracking is greatly affected by how the eye tracking algorithm is implemented in addition to hardware variables. Accordingly, in this paper, we propose a method to estimate how many degrees of gaze changes when the pupil center moves by one pixel by estimating the maximum possible movement distance of the pupil center in the image.

The purpose of this study is to propose a throughput costing as a performance measurement tool to measure cost indicators, which are one of the indicators for evaluating organizational performance in a smart factory manufacturing environment. An empirical study by questionnaire was conducted, and 60 experts were surveyed to verify the hypothesis. As a result of the study, it was concluded that the information provided based on throughput costing is helpful in cost measurement and in evaluating organizational performance efficiency and effectiveness, and it was confirmed that this method has usefulness to support the planning and control process. It is proposed that the use of throughput costing by constraint theory, which can maximize throughput and optimize inventory levels in the manufacturing process, can find solutions to bottlenecks affecting the efficiency and effectiveness of organizational performance.

In the field of speech recognition, as the DNN is applied, the use of speech recognition is increasing, but the amount of calculation for parallel training needs to be larger than that of the conventional GMM , and if the amount of data is small, overfitting occurs. To solve this problem, we propose an efficient method for robust voice feature extraction and voice signal noise removal even when the amount of data is small. Speech feature extraction efficiently extracts speech energy by applying the difference in frame energy for speech and the zero-crossing ratio and level-crossing ratio that are affected by the speech signal. In addition, in order to remove noise, the noise of the speech signal is removed by removing the noise of the speech signal with an average predictive improved LMS filter with little loss of speech information while maintaining the intrinsic characteristics of speech in detection of the speech signal . The improved LMS filter uses a method of processing noise on the input speech signal by adjusting the active parameter threshold for the input signal. As a result of comparing the method proposed in this paper with the conventional frame energy method, it was confirmed that the error rate at the start point of speech is 7% and the error rate at the end point is improved by 11%.

The purpose of this study is to find out whether critical thinking education improves critical thinking disposition of nursing college students. The participants were 173 second graders. The education was conducted three times, two hours each, for a total of six hours of intensive critical thinking education and continuous education during Nursing Process class. The survey was conducted in the first week and 14th week of the course. The collected data was analyzed with IBM SPSS 21.0. Findings: The results showed that the average rating of critical thinking before and after education was raised(3.65±0.41→3.83±0.46, t=6.796, p<.001). Among the sub-items, creativity, which had the lowest score before education, has been raised the most(3.13±0.78→3.43±0.86, t = 5.842, p<.001). The effectiveness of critical thinking education has been confirmed. But it is a lack of evidence on the relevance of the details. It is suggested that repeated research is needed to ensure the quality of education, develop teaching methods, and develop tools for verifying effectiveness.

With the rapid development of advanced science and technology including the 4th industrial revolution, the future battlefield environment is evolving at a rapid pace. In order to actively respond to issues such as reduction of military resources and shortening of service period, and to emphasize the realization of human-centered values, the Ministry of National Defense is re-establishing the role of the Army in accordance with the defense reform and is promoting the Warrior Platform, a next-generation individual combat system. In this paper, we intend to present the optimal warrior platform architecture suitable for the Korean Army by realizing the concept of future ground operations and analyzing overseas cases. We analyze the essential abilities required of individual combatants and the abilities required for each unit type, and specifically presents a plan for integration and linkage of warrior platform equipment. We also propose an efficient business promotion direction by presenting the data flow and power connection diagram between the devices that need integration and interworking.

This study was conducted to identify the correlation between the self-efficacy, communication competence, and clinical practice satisfaction of dental hygiene students and the factors affecting clinical practice satisfaction. The data survey was conducted on 201 students of Chungcheong Province who experienced clinical practice. Data were analyzed by anova and logistic regression analysis. As a result of the study, clinical practice satisfaction was positively correlated with self-efficacy (r=.337), communication competence (r=.293) and self-efficacy was positively correlated with communication competence (r=.633). Factors affected to clinical practice satisfaction were self-efficacy, academic score, and major satisfaction. Therefore, it will be necessary to develop clinical practice education programs that can enhance students' self-efficacy and improve their communication competence.

Among the elderly and patients with mild brain diseases (such as dementia and stroke), when there is a certain degree of self-acting ability and cognitive ability, exercise and cognitive rehabilitation are often required. However, since most of the existing rehabilitation systems are separated or specialized in exercise or cognitive rehabilitation, there is a need for a form linking both. In this paper, we propose a game-type rehabilitation system that enables both exercise and cognitive rehabilitation using CAN communication protocol, one of ICT technologies. This system uses the CAN BUS structure to separate and combine each individual module constituting the rehabilitation system in various forms. A prototype of the proposed system was actually produced to show that various types of rehabilitation environments can be implemented according to the degree of cognitive ability and motor ability of the patient (or the elderly). In addition, through several experiments using this system, it is possible to implement exercise/cognitive parallel rehabilitation applicable to various environments.
