Microelectronic product consumers may already be expecting another paradigm shift with smarter phones over smart phones, but the current status of microelectronic manufacturing engineering education (MMEE) in universities hardly makes up the pace for such a fast moving technology paradigm shift. The purpose of MMEE is to educate four-year university graduates to work in the microelectronics industry with up-to-date knowledge and self-motivation. In this paper, we present a comprehensive curriculum for a four-year university degree program in the area of microelectronics manufacturing. Three hands-on experienced-based courses are proposed, along with a methodology for undergraduate students to acquire hands-on experience, towards integrated circuits (ICs) design, fabrication and packaging, are presented in consideration of manufacturing engineering education. Semiconductor device and circuit design course for junior level is designed to cover how designed circuits progress to micro-fabrication by practicing full customization of the layout of digital circuits. Hands-on experienced-based semiconductor fabrication courses are composed to enhance students’ motivation to participate in self-motivated semiconductor fab activities by performing a series of collaborations. Finally, the Microelectronics Packaging course provides greater possibilities of mastered skillsets in the area of microelectronics manufacturing with the fabrication of printed circuit boards (PCBs) and board level assembly for microprocessor applications. The evaluation of the presented comprehensive curriculum was performed with a students’ survey. All the students responded with “Strongly Agree” or “Agree” for the manufacturing related courses. Through the development and application of the presented curriculum for the past six years, we are convinced that students’ confidence in obtaining their desired jobs or choosing higher degrees in the area of microelectronics manufacturing was increased. We confirmed that the hypothesis on the inclusion of handson experience-based courses for MMEE is beneficial to enhancing the motivation for learning.

일반인 중 심정지를 목격할 가능성이 가장 높은 중년층 여성들을 대상으로 숫자를 세는 방법에 따른 가슴압박소생술의 질과 피로도를 비교하여 최초반응자로서의 역할을 위한 심폐소생술 교육 프로그램을 마련하는데 기초자료를 제공하고자 한다. 3시간의 기본인명구조술 교육을 실시한 후, 확률할당을 통해 45명씩 두 그룹으로 배정하였다. 가슴압박소생술 도중 큰소리로 숫자를 세는 그룹 A, 숫자를 세지 않는 그룹 B로 나누어 인체모형에 2분간의 연구를 진행 하였다. 두 그룹간 가슴압박의 질은 유의한 차이를 보이지 않으면서 가슴압박의 중단시간이 단축되었고, 시간의 경과에 따라 흉부압박의 깊이가 줄어드는 빈도 또한 의미 있게 낮았다. 또한 가슴압박소생술 후 본인이 느끼는 피로도 또한 의미 있게 낮았다.

Background: The purpose of this study was to identify the connection between handwashing and toothbrushing, focusing on eating habits, and to verify whether eating habits can be used as an action cue for forming health habits. Methods: This was a cross-sectional study using secondary data from the 2019 community health survey. The participants included 229,099 adults aged 19 years or older, representative of the South Korean people. We employed two dependent variables: one was washing hands, and the other was brushing teeth. Eating habits was a major independent variable. Socioeconomic variables, such as age, gender, income, occupation, economic activity, education, and residence were adjusted as confounders. Multivariate logistic regression was performed to calculate adjusted odds ratio and 95% confidence intervals. Results: Most of the participants had good health behaviors: those who wash their hands and brush their teeth were each approximately 80%. Our finding indicated that brushing teeth and washing hands can be connected with eating habits. After adjusting for confounders, it was found that people who wash their hands before meals (compared to those who did not wash their hands before meals) had a higher toothbrushing rate after meals (i.e., socioeconomic status) (Adjusted Odds Ratio: 2.0, Confidence Intervals: 1.9 to 2.1). Conclusion: Those who practice either washing hands before meals or brushing teeth after meals were found to have a connection between washing hands and brushing teeth based on the results of practicing other health behaviors. This implies that eating habits can be connected as a behavior cue to promote health habits, such as washing hands before meals and brushing teeth after meals.

로봇을 통한 창의성과 문제해결력 신장에 대한 기대뿐만 아니라 영재교육 등의 다양한 요구에 의해 사교육 및 방과후학교 로봇교실은 매우 활성화되어 있다. 그러나 로봇교육은 인지적 영역뿐만 아니라 정의적 영역에 대한 효과도 매우 크게 기대되는데, 경제적 형편이 어려운 아동에게는 로봇키트 등의 가격 부담으로 균등한 기회조차 주워지지 못하는 실정이다. 이에 본 연구에서는 서울시의 u-러닝 사업의 일환으로 저소득층 아동들을 대상으로 통제집단과 실험 집단으로 나누어 무상으로 1년간 로봇교육을 실시하여, 정의적 영역과 인지적 영역 그리고 창의성의 유창성 부분에서 어떠한 변화가 일어나는지에 대한 관찰연구를 실시하고 있다. 이에 본 연구에서는 서울시의 u-러닝 사업의 일환으로 저소득층 아동들을 대상으로 통제집단과 실험집단으로 나누어 무상으로 1년간 로봇교육을 실시하여, 정의적 영역과 인지적 영역 그리고 창의성의 유창성 부분에서 어떠한 변화가 일어나는지에 대한 사전사후 비교연구를 실시하고 있다. 현재까지 관찰로 아이들의 태도가 변화하는 성공사례들이 나타나고 있어, IT와 접목된 로봇교육을 통하여 저소득층 아동의 창의적이고 자발적인 태도를 육성하기 위한 가능성이 보여진다.

Objectives: The aim of this study was to investigate the impact of oral hygiene education provided by dental hygienists in patients with dental implants. Methods: Data were obtained from a survey that involved 300 patients who had one or more dental implants. Based on the calculated sample size (n = 274), 300 questionnaires were used for further analyses. Results: The patients who received oral hygiene education had higher levels of satisfaction after dental implant surgery (p<0.05). Patients who had repeated educational sessions, in the form of interactive or hands-on sessions or lectures, with continuous feedback had higher scores for oral hygiene maintenance (p<0.05). Conclusions: This study indicated that patients who received oral hygiene education, in the form of interactive or hands-on sessions or lectures, with continuous post-educational feedback were better at maintaining oral hygiene.

Purpose: The object of this study was to compare the educational effect about self-efficacy and the quality of chest compressions of Hands-only CPR and Basic CPR. Methods: It's a nonequivalent control group pre-post repeated quasi-experiment study conducted with entire fifth grade students belong to one school in H city. The study participants are 68 persons, and data were collected from December 2, 2013 to February 7, 2014. Self-efficacy was measured by 10 items, and the quality of chest compressions was measured by 5 variables which are average compression depth(mm), average rate (n/min), average count per minutes (n), abnormal placement (n), compression accuracy (%). Results: Self-efficacy of the experimental group and control group showed no significant difference but showed significant difference over time and was the highest at posttest 1 (immediately after education), the lowest at pretest (before education), middle at posttest 2 (8weeks after education) (p<.001). Experimental group was significantly higher than control group in average rate per minute. At posttest 1, experimental group was $130.0{\pm}9.38$ times, control group was $95.1{\pm}11.82$ times. At posttest2, experimental group was $124.0{\pm}14.89$ times, control group was $90.8{\pm}14.89$ times.(p<.001). Average rate (n/min) was significantly declined at control group in the quality of chest compressions over time (t=-2.400, p=.022). Average count per minute and compression accuracy were declined significantly so it were not maintained to posttest2. Conclusion: We need continuous CPR education because self-efficacy of CPR getting lower significantly over time. Hands-only CPR can't be seen as a way to increase the CPR ability of elementary school students having difficulty to perform artificial breathing. And, because the effect of education is not maintained 8wks after training, the technique centered repeated training is needed and a method which can increase compression accuracy is also needed.
