Purpose: The purpose of the study is to analyze the effects that Flipped Learning Method has on a college student's self directed learning ability, critical thinking disposition, learning motivation, and learning satisfaction, and determine its effectiveness as a new pedagogical approach. Methods: The survey was conducted on dental technology students. The collected data was analyzed by the statistical program SPSS 21.0. The results were analyzed by reliability, frequency, t-test. To test for significance on each item, p<0.05 has been decided as a standard. Results: According to the analysis, the student who attended a class that utilized Flipped Learning Method was found to have higher levels of self directed learning ability, critical thinking disposition, learning motivation, and learning satisfaction than a student who attended a class that did not utilize such a method. Conclusion: The study results show that, in order to enhance students' self directed learning ability, critical thinking disposition, learning motivation, and learning satisfaction and to improve the quality of class instruction, it may be necessary that Flipped Learning Method be adopted more widely and recommended more strongly. Such changes will promote a long term improvement in educational environments and play a major role in strengthening students' abilities.

Purpose: This study aimed to investigate the effect of stress and oral parafunctional habits on temporomandibular joint disorders (TMD) in college students. Methods: An online survey comprising 354 questionnaires was conducted from May 23, 2020, to June 21, 2020. The collected data were analyzed using Student's t-test, one-way analysis of variance, correlation tests, and multiple regression analysis. Results: The stress symptom score was higher in females than in males. The symptoms of physical stress were significantly higher among students from the Department of Public Health, whereas those of psychological stress were higher among students from the Department of Physical Education. Both TMDs and oral parafunctional habits were higher among females, students of the Departments of Arts and Physical Education, and seniors. The higher the stress symptom level, the higher the scores for TMD and oral parafunctional habits. TMD and oral parafunctional habits were found to be most affected by physical stress. Conclusion: These findings indicate that a reduction in physical stress is required to decrease the prevalence of oral parafunctional habits and TMDs among college students. This can be achieved by the incorporation of physical activity programs, which may aid in reducing the symptoms of physical stress.

Purpose: This study aims to prevent Smartphone addiction and provide a basic material for intervention strategy by inquiring into the correlation between interpersonal relations competency and Smartphone addiction. Methods: This study carried out a questionnaire survey oriented to 323 people who agreed to participate in this research. For the final analysis, this study selected 298 sheets of questionnaires excluding 25 sheets with insufficient response qualities. Results: According to the results of regression analysis, significant correlation between interpersonal relations competency and Smartphone addiction level was not observed. However, according to the results of correlation analysis, the subordinate factor of Smartphone addiction "directionality of virtual world" showed a significant negative correlation with "opinion expression regarding rights or refusal" of interpersonal relations competency (p<0.05), while "withdrawal," the subordinate factor of interpersonal relations competency and Smartphone addiction displayed a negative correlation with Smartphone addiction (p<0.05). Conclusion : However, the mean of the 3DP group was within the clinical tolerance suggested by the previous researchers. Based on this, dental prosthesis fabricated by 3D printing technology is considered to be clinically acceptable.

Purpose: The present study is an analysis of the extents of class satisfaction of college students who had applied the design thinking technique to capstone design class. Methods: The experimental method involved an analysis of 122 cases of data where advance and post replies were performed for the subject by students who had applied the design thinking technique and students who had not. The students involved had attended the capstone design class as a junior in the Department of Dental Technology at D University. Results: In the satisfaction with performance process of the capstone design class, five questions among nine had a high positive rating, while all eight questions on the satisfaction with performance methods had a high negative rating. Among ten questions on subjective learning outcomes, six showed a high positive rating. After the application of the design thinking class method, all mean values of the group with the application were higher than the group with no application in satisfaction with performance process, satisfaction with performance method, and subjective class outcomes. Hence, the design thinking class did have positive effects on the students' improvement of class. Conclusion: Based on the results of the study, it is implied that the considerations about diverse class composition methods and operation methods capable of improving the students' satisfaction are needed for efficient operation of the capstone design class.

The purpose of this study was to investigate the correlation between wearing masks and subjective symptoms of halitosis in the COVID-19 situation. The survey was conducted from June 15 to July 31, 2022, among university students aged 19 years or older in Daegu and Gyeongbuk, 1. Subjective symptoms of halitosis were found to be higher in males and students being treated for periodontal diseases. 2. The subjective symptoms of halitosis were found to be higher in subjects with psychological anxiety, even though they did not have halitosis. 3. As a result of examining the subjective symptoms of halitosis, it was found that there were more subjects who were aware of halitosis while wearing a mask than those who were not. In view of the above results, it is thought that because of prolonged wearing of masks due to the COVID-19 pandemic situation, the difficulty faced in oral health management increases the symptoms of halitosis. Therefore, it is considered that oral health education in the era of corona should be accompanied by proper wearing of masks and halitosis management education.

저작은 치아, 악골, 저작근 뿐만 아니라 근 신경계, 고위 중추까지 복합적으로 관여되는 기능적 행위이다. 저작 형태는 다양한 모양을 가지나 두 가지 전형적인 군, 즉, 전방에서 관찰 시 그 양상이 수직적이며 절단 (chopping) 운동을 하는 군과 주로 측방으로 이루어지며 연마 (grinding)를 하는 군으로 나눌 수 있다. 본 연구의 목적은 저작 형태의 차이가 교합면 마모에 미치는 영향을 조사하는 것이다. 두개 하악 관절과 저작 습관에 이상이 없으며 교합면에 수복물이 없는 치과 대학생으로 하악 운동 궤적 기록기를 이용하여 상기의 전형적인 2가지 저작 형태를 보이는 각 15명씩을 피검자로 선택하였다. 각 피검자에 대한 임상 검사를 통해 ordinal scale로 교합면 마모의 등급을 조사하여, 평균 치아 마모도와 부위에 따른 치아 마모도를 비교 조사하였다. 각 피검자에 대한 인상 채득 후 모형을 제작하고 arbitrary scale로 교합면 마모의 등급을 조사하여, 평균 치아 마모도와 부위에 따른 치아 마모도를 비교 조사하고 저작측과 비저작측 마모를 비교 조사하였으며 수평 마모면과 수직 마모면을 비교 조사하였다. 1. 평균 치아 마모도는 ordinal scale로 측정하였을 때, 절단형과 연마형간에 유의할 만한 차이가 없었다.(p >0.05) 2. 부위에 따른 치아의 마모도는 ordinal scale로 측정하였을 때, 절단형과 연마형간에 유의할 만한 차이가 없었다.(p >0.05) 3. 평균 치아 마모도는 arbitrary scale로 측정하였을 때, 절단형에 비교하여 연마형에서 높은 마모도를 보였다.(p<0.05). 4. 절단형에 비교하여 연마형은 arbitrary scale로 측정하였을 때, 구치부에서는 높은 마모도를 보였으며 전치부에서는 유의할 만한 차이가 없었다(p<0.05) 5. 구치 평균 치아 마모도와 부위에 따른 치아의 마모도는 균형측에서 절단형과 연마형간에 유의할 만한 차이를 보이지 않았다(p>0.05). 6. 전치 평균 치아 마모도와 부위에 따른 치아의 마모도는 수평 마모면과 수직 마모면 비교시, 절단형과 연마형간에 유의할 만한 차이를 보이지 않았다.(p>0.05)

저작은 교합과 악운동 뿐만 아리라 근신경계, 고위 중추까지 복합적으로 관여하는 기능적 행위이다. 교합 양상은 다양하게 저작 형태에 영향을 끼치며 저작 효율에도 관여한다. 저작 형태는 다양한 모양을 가지나 두가지 전형적인 군 즉, 전방에서 관찰시 그 양상이 수직적이며 chopping운동을 닮은 군과 저작 형태가 주로 측방으로 이루어지며 grinding을 하는 군으로 나눌 수 있다. 본 연구의 목적은 저작 형태의 치아가 교합접촉 및 저작 효율에 미치는 영향을 고찰해 보고자 하는 것이다. 하악운동궤적기록기를 이용하여 정상교합을 가진 치과대학생중 전형적인 2가지 저작형태를 보이는 각 10명씩을 피검자로 선택하였다. 3가지 하악위 즉, 중심위, 작업측 비작업측에서의 교합접촉을 고무형 교합인기재로 기록하여 천공부의 직경이 1mm이하면 1점, 1-2mm또는 직선상이면 2점, 2mm이상이면 3점으로 평가하여 각 점수의 합으로 좌우 소구치 및 대구치의 접촉 지수를 측정하였다. 저작 효율을 평가하기 위해 땅콩 3g(${\pm}0.01g$)을 20회 저작하게 한 후 3회 입을 헹구어 뱉게 하였다. 체눈 크기가 각 0.425, 0.60, 0.85, 2.0, 4.0인 체에 거른 후 $65^{\circ}C$로 오븐에서 세시간 말려 무게를 측정하고 중심 크기$(M_{50})$과 저작효율치(R)를 계산 비교하여 다음과 같은 결론을 얻었다. 1. Chopping형은 grinding형에 비해 중심위에서 더 넓은 교합접촉을 보였다(P<0.01). 2. Grinding형은 chopping형에 비해 측방위에서 더 넓은 교합접촉을 보였다(P<0.01). 3. Chopping형은 중심크기($(M_{50})$)과 저작효율치(R)로 비교하였을 때 더 좋은 저작 효율을 보였다(P<0.01).
