Long-term survival and prognosis of narrow-diameter implants have been reported to be adequate to consider them a safe method for treating a deficient alveolar ridge. The objective of this study was to perform case report of narrow-diameter implants with a trapezoid-shape in anterior teeth alveolar bone. A 50-year-old male patient presented with discomfort due to mobility of all of the maxillary teeth and mandibular incisors. Due to destruction of alveolar bone, four anterior mandibular teeth were extracted. Soft tissue healing was allowed for approximately 3 months after the extraction, and a new design of implant placement was planned for the mandibular incisor area, followed by clinical and radiological evaluation. Implant placement was determined using an R2GATE surgical stent. The stability of the implants was assessed by ISQ measurements at the first and second implant surgery and after prosthetic placement. At 1 and 3 months and 1 year after implantation of the prosthesis, clinical and radiological examinations were performed. Another 50-year-old male patient presented with discomfort due to mobility of the mandibular central incisors. For the same reason as in the first patient, implant placement was carried out in the same way after extraction. ISQ measurements and clinical and radiological examinations were performed as in the previous case. In these two clinical cases, 12 months of follow-up revealed that the implant remained stable without inflammation or additional bone loss, and there was no discomfort to the patient. In conclusion, computer-guided implant surgery was used to place an implant in an optimal position considering the upper prosthesis. A new design of a narrow-diameter implant with a trapezoid-shape into anterior mandibular alveolar bone is a less invasive treatment method and is based on the contour of the deficient alveolar ridge. Through all of these procedures, we were able to reduce the number of traumas during surgery, reduce the operation time and total treatment period, and provide patients with more comfortable treatment.

본 연구는 고등학생 대상 ｢식품안전과 건강｣의 교육과정 운영 효과를 알아보는데 목적이 있다. 이에 충북, 경기, 대전, 세종지역의 6개 고등학교에서 ｢식품안전과 건강｣교육과정의 일부가 시범 운영되었고, 수업에 참여한 학생으로부터 수집된 1,199부를분석하였으며 그 결과는 다음과 같다. ｢식품안전과 건강｣수업은 고등학생의 ‘식품안전과 건강’ 지식 총점 및 각 영역별 점수향상에 유의한 효과가 있었다. 사전검사에 비해 사후검사 정답률은 전체적으로 7.99%p 높였으며, 해당 영역을 상대적으로 많이교육한 학교의 향상 점수가 높게 나타났다. 또한 ｢식품안전과 건강｣수업은 고등학생의 식생활 행동을 긍정적으로 변화시켰고, 여러 가지 음식을 골고루 먹는 식습관을 가지게 하는 데 유의한 효과가 있었다.｢식품안전과 건강｣수업에 참여했던 고등학생들은수업에 대하여 매우 긍정적으로(4.27/5) 평가하였으며, 수업 내용이 흥미롭고, 이해하기 쉬웠으며, 실제 식생활에 도움이 된다고답하였다. 개방형 질문에 대한 답을 분석한 결과, 수업에서 좋았던 점은 식품관련 지식 습득, 실생활에 도움이 되었다는 의견이많았으며, 아쉬운 점으로 코로나로 인하여 수업이 온라인으로 진행되어 실습이나 모둠 활동을 못한 점 등을 꼽았다. 본 연구는고교학점제에 대비하여 가정계열 선택과목 편성 확대 및 고등학생의 과목 선택권 확대에 의의가 있다. The purpose of this study was to examine the effectiveness of the curriculum implementation of ｢Food Safety and Health｣, a Home Economics elective course, for high school students. Accordingly, several units of the ｢Food Safety and Health｣curriculum were piloted in six high schools in Chungbuk, Gyeonggi, Daejeon, and Sejong, and 1,199 questionnaires collected from students who participated in the classes were analyzed. The results are as follows. The ｢Food Safety and Health｣class had a significant effect on improving the total score of ‘food safety and health’ knowledge of high school students and scores for sub-dimensional area. Compared to the pre-test, the overall rate of correct answers for the post-test has increased by 7.99%p, and schools that implemented the relevant unit class relatively more had higher improvement scores. In addition, the ｢Food Safety and Health｣class has positively changed the eating behavior of high school students, and had a significant effect on having a habit of eating a variety of foods evenly. High school students who participated in the ｢Food Safety and Health｣class evaluated their classes very positively (4.27 out of 5 points), and responded that the content of the class was interesting, easy to understand, and helpful for their diet in daily life. According to the responses to the open-ended questions, students responded that the class was helpful in acquiring food-related knowledge in their real lives, while there were so many limitations for experiencing lab class and group activities due to COVID 19. In preparation for the high school credit system, this study is meaningful that it has expanded the elective courses in home economics area, as well as the right to choose subjects for high school students.
