This paper presents a robust vibration control methodology of smart structural systems. The governing equations and associated boundary conditions are derived by Hamilton's principle. A robust controller is designed using a linear matrix inequality (LMI) approach to the multiobjective synthesis. The design objectives are to achieve a mix of H$\sub$$\infty$/ performance and H$_2$ performance satisfying constraints on the closed-loop pole locations in the face of model uncertainties. Numerical examples are presented to demonstrate the effectiveness of LMI approach in damping out the multiple modes of vibration of the piezo/beam system.

In this study, remote articulation training system which connects the hearing disabled trainee and the speech therapist via B-ISDN is introduced. The hearing disabled does not have the hearing feedback of his own pronuciation, and the chance of watching his speech organs movement trajectory will offer him the self-training of articulation. So the system has two purposes of self articulation training and trainer's on-line checking in remote place. We estimate the vocal tract articultory movements from the speech signal using inverse modelling and display the movement trajectoy on the sideview of human face graphically. The trajectories of trainees articulation is displayed along with the reference trajectories, so the trainee can control his articulating to make the two trajectories overlapped. For on-line communication and ckecking training record the system has the function of video conferencing and tranferring articulatory data.

Recently, wearable computers equipped with various biosensors such as smart watches, smart bands, and smart patches that support daily health management of users as well as patients have been released. Users of wearable computers such as smart watches face various difficulties in performing biometric information processes such as data sensing, collection, transmission, real-time analysis, and feedback in a weak wireless and mobile biometric information service environment. In particular, the biometric information collection interface is an important basic process that determines the quality and performance of the entire biometric information service. So far, research has focused on sensing hardware and logic. This study intensively considers the interface method for effectively sensing and collecting raw biometric information. In particular, the process of collecting biometric information is designed and analyzed from the perspective of periodicity. Therefore, we propose an efficient and stable periodic collection method.

The important developmental tasks of young adults are based on encounter and identity. These problems of encounter and identity are also connected to the instinct of longing for the "face" of primary caregivers, who acknowledge and affirm themselves as their cherished children. James Loder emphasizes that human "face pursuit instinct" later reaches "formal-operational stage" and leads to religious yearning for God as "the Eternal Face." This pursuit of "face" and "the Eternal Face" is an existential and ontological move to find out "Who am I?" through meaningful encounters. Religious psychologist Carl Jung also points out that scientific thinking has contributed to the liberation of humans from superstitious beliefs. But this has also led to the loss of the precious value of human spirit and the sense of unity with nature. Jung emphasizes that "symbolic play" should help learners and counseler face-to-face with their unconscious mind. By doing so, learners can overcome the wounds and scars of unconsciousness and mature toward the true self. James Loder is a scholar who critically introduced Jung's "unconscientious confrontation" therapy to his educational theory. Beyond Jung's unconsciousness and "symbolic play," Loder proposed transformational education for the learners to participate in meaningful changes through interaction between human spirit and the Holy Spirit. With many young adults wandering around in their existential voids, it is clear that functional and socializational education cannot overcome their problems and developmental crisis. This developmental crisis requires a foundation of identity and intimacy in the encounter with God, the "Eternal Face." Therefore, this study suggests that when Jung's "unconscious confrontation" and Loder's "transformation logic" are employed, transformational Christian education for the healthy self-identity and intimacy of young adults can be accomplished. This inquiry presents not only theoretical reflection, but also the reactions of young adults and actual feedback obtained through implementing transformational Christian education for young adults. Through all of these endeavors, this inquiry was completed by proving that "Transformational Christian Education for Young Adults" is an educational theory that can yield actual results and abound fruits. (This enquiry was undertaken by the support of the research fund of PUTS 2020.)

This study is a qualitative study to explore the experiences of nursing students' psychological nursing practice in-school. The subjects of this study were 62 students who were the 3rd grade nursing students at a University in Gangwon-do. The data were collected from August 3rd to August 20th, 2020. For data analysis, Colaizzi's qualitative analysis method was applied. Six categories were derived from data analysis: 1) Lingering affection for clinical practice in field. 2) Achievement through learning 3) Fear of nurse's role in future 4) Burden for many tasks 5) Feeling free of stress from clinical practice in field 6) Importance of cooperation with other departments. The positive aspects of in-school practice education, which from nursing students' evaluation, were immediate feedback, detailed explanations, and indirect experiences. Based on this study result, it is recommended to develop in-school nursing practice education program for gap-reducing with clinical practice. It would be consisted of various contents: simulation, online/non-face-to-face practice, face-to-face practice for indirect experience. In addition, these multi-aspect effort is needed more in psychological nursing practice education to reduce the gap with clinical practice such as therapeutic communication and hallucination interventions.

In recent years, university education has emphasized a learner-centered education model with a change in educational paradigm. This study aims to explore students' diverse opinions and improve the quality of education by analyzing the open-ended responses of university lecture evaluations using topic modeling. To this end, a total of 45,001 open-ended responses based on the results of lecture evaluations from 2017 to 2022 in non-metropolitan universities were divided into majors and liberal arts, and a short-form optimized Biterm Topic Modeling (BTM) analysis was conducted. As a result of the analysis, major lectures were divided into "attitude toward non-face-to-face classroom experience", "attitude toward questions and discussions", "attitude toward attendance and grading", "attitude toward practical activities and presentations", and "attitude toward communication and collaboration", while liberal arts lectures were divided into "attitude toward non-face-to-face classroom experience", "attitude toward grades and evaluations", "attitude toward attendance and syllabus", "attitude toward academic knowledge and interest", and "attitude toward communication and questions". The results of this study, which analyzed various feedback from students, provide insights that can be used to compare the characteristics of majors and liberal arts courses and improve teaching and learning experiences.

This study aims at reviewing the effect of the non-verbal communication of salespersons at service encounter on customers' non-verbal communication and responses. The previous studies overlooked the correlation between salespersons' non-verbal communication and customers' non-verbal communication at service encounter, although non-verbal communication of salespersons has potentialities evoking customers' non-verbal communication and emotional responses in various ways. If it is a salesperson who a customer first encounters within a shop, the non-verbal communication of salesperson affects his/her non-verbal communication and these non-verbal communication affect his/her emotional responses, and these emotional responses affect his/her behavior. This phenomenon is based on the theory of emotional contagion, mimic, and face feedback. Therefore the non-verbal communication such as greetings, postures and eye-contact manners through the personal interactions between salespersons and customers, can be said to be an antecedent variable which affects the positive responses of customer. As a result of the study, the kinesic of salesperson's non-verbal communication was found to affect customers' non-verbal communication, and customers' non-verbal communication affect emotional responses experienced at service encounter, and customers' positive emotion affect customers' behavior responses. This result provides an opportunity which makes one turn eyes on salespersons' non-verbal communication at sales encounter both practically and scientifically, through introducing salespersons' non-verbal communication as an important factor which can enhance customers' positive responses but has been passed over by the previous studies.

This study tried to develop and implement a class model that can apply the teaching method that can operate learner-centered classes in university education to the class operation of the entire university, not individuals. For the development of the instructional model, the final model was derived through analysis of prior research, expert review, derivation of instructional model and design principles, pilot operation, primary questionnaire analysis, model and design strategy revision, and secondary questionnaire analysis. Shift_N⁺¹ class consists of 6 models, and each model was divided into 3 parts. It was a preliminary learning using video, a face-to-face class for question-and-answer and in-depth learning on the core content, and feedback and process evaluation for individual student. We have built our own computer system so that we can implement this every week. The teaching method model that can apply the learner-centered curriculum to all classes at the university was standardized. The Shift_N⁺¹ teaching method seeks to maximize the learner-centered learning effect by reflecting the characteristics of the subject, and to improve the quality of education by identifying students' achievements by week.

Skin color segmentation techniques have been widely utilized for face/hand detection and tracking in many applications such as a diagnosis system using facial information, human-robot interaction, an image retrieval system. In case of a video image, it is common that the skin color model for a target is updated every frame for the robust target tracking against illumination change. As for a single image, however, most of studies employ a fixed skin color model which may result in low detection rate or high false positive errors. In this paper, we propose a novel method for effective skin color segmentation in a single image, which modifies the conditions for skin color segmentation iteratively by the image feedback of segmented skin color region in a given image.
