Objectives: This study aims to identify factors that lower school life burnout by identifying the effects of dental hygiene students' major satisfaction, positive psychological capital, and clinical practice stress on school life burnout, and to suggest ways to increase satisfaction with students' school life. Methods: From August 1 to 30, 2022, 250 dental hygiene students with clinical practice experience were conveniently extracted from among dental hygiene students in Chungcheong, Gyeongsang, and Jeolla regions, and questionnaires were distributed to those who agreed to fill out the data. Results: Factors influencing school life burnout of students majoring in dental hygiene showed significant relationships in positive psychological capital, major satisfaction, and clinical practice stress, and the explanatory power was 37.5%. Conclusions: As a result, it seems necessary to develop a psychological education program that can improve major satisfaction and positive psychological capital, reduce clinical practice stress, and reduce school life exhaustion in order to control the factors affecting dental hygiene students' school life exhaustion.

Objectives: This study sought to identify dental hygiene students’ adult attachment, interpersonal competence, self-respect, and sociable support, and to identify factors that affect interpersonal competence. Method: A self-administered survey was conducted on 180 students attending dental hygiene schools nationwide from 14 February to 30 May, 2023. Descriptive statistics, t-test, one-way ANOVAs, Pearson correlation coefficient, and stepwise multiple linear regression analys were used, as determined by the SPSS 26.0 program. Results: Dental hygiene students’ interpersonal competence measured 3.61 points, adult attachment measured 3.44 points, self-respect measured 3.44 points, and sociable support measured 4.00 points. In terms of general characteristics, significant differences were found in satisfaction with college life and club membership. Interpersonal competence was positively correlated with adult attachment, self-respect, and sociable support. The factor that had the greatest impact on interpersonal competence of dental hygiene students was sociable support, with an explanatory power of 37.3%. Conclusions: In order to improve the sociable support for dental hygiene students, a social activity support network within and outside of school is needed.

Objectives: This study aims to identify the effect of problem-solving and interpersonal ability on clinical practice satisfaction for dental hygiene students and use them as basic data necessary for developing programs to improve students' problem-solving, interpersonal skills, and clinical practice satisfaction. Methods: Dental hygiene students in Daejeon who experienced clinical practice from April 1 to April 30, 2022 were asked to fill out a self-reported questionnaire through a random sampling method. Results: Problem-solving ability was the most influential factor on satisfaction with clinical practice, and explanatory power was 21.7%. Conclusions: As a result of the above, it seems necessary to improve interpersonal skills and problem-solving skills, cooperate with school activities and practice institutions to improve clinical practice satisfaction, and improve clinical practice curriculum.

해양 센서 네트워크를 구성하는 센서노드는 배터리로 구동되기 때문에 전력의 한계가 있고, 전력이 소진되었을 때 사람이 직접 가서 충전 하기 어렵다. 해양 센서 네트워크는 매질의 특성상 장파인 음파로 통신을 하는데, 최근 연구에 의해 초음파를 이용해서도 통신이 가능하다고 알려져 있다. 지상에서는 초음파를 이용하여 무선으로 전력을 전송하는 것이 실험으로 증명되었다. 본 논문에서는 해양 센서 네트워크에 초음파로 전력을 충전하는 개념을 적용하였다. 이를 위해서 센서노드와 전력전송노드의 구조를 설계하고, 전력을 전송하는 절차에 대해 기술하였다. Life time of battery is crucial issue for the battery-powered sensor nodes of the Underwater Sensor Network(UWSN). It is impractical for a human to go underwater to charge or replace the battery when the electric power is exhausted. Recently research showed that it is possible to transmit electric power using the ultrasonic waves. This paper applies the concept of charging power with ultrasonic waves to UWSN. The functional structures of the sensor nodes and the power transmission node are described, and the procedure to transmit the power is proposed.

본 논문에서는 팔동작 기반의 사용자 인터페이스를 위한 효율적인 패턴 비교 기법을 소개한다. 패턴 비교의 실행 시간을 줄이는 방법으로서 비교 대상 패턴의 개수를 줄이는 방법과 패턴 비교에 쓰이는 DTW 알고리즘을 패턴의 일부 구역에만 적용함으로써 비교 실행 시간을 줄이는 방법을 제안한다. 비교 실행 시간을 줄이는데 필요한 데이터를 추출하는 프로파일링 기법과 DTW 알고리즘에 윈도우를 적용하는 변형된 DTW 알고리즘을 정의한다. 본 논문에서 정의하는 기법을 사용하는 패턴 비교 방법이, 기법을 사용하지 않은 패턴 비교에 비해서 실행 시간을 얼마나 개선하였는지 실험 결과를 제시한다. An efficient pattern comparison method for the motion-based user interface is proposed in this paper. In order to reduce the execution time for comparison of the patterns, the proposed method reduces the number of patterns to compare and the execution time of DTW algorithm. To do this, a profiling mechanism is proposed to extract the length of pattern and shape data to reduce the pattern comparison time. Incremental approach of applying pattern data to the DTW algorithm using the window concept is also proposed. The experiments show that performance of the pattern comparison using the proposed method is much better than traditional methods.
