Objectives:This study aimed to assess the possible association of dental pain with suicidal ideation among adolescents by analysing data from the 2018 Korean Youth Risk Behavior Survey, a nationwide online survey. Methods:Of 62,823 adolescent middle and high school students in Korea, 60,040 participants were selected for analysis, after excluding cases with missing values. Participants were given a questionnaire about their self-evaluation of health including dental pain and suicidal ideation. Logistic regression analysis demonstrated the relationships between dental pain and suicidal ideation after controlling for potential confounding factors. Results:The proportion of Korean adolescents reporting suicidal ideation was 13.3%. The proportion of adolescents who experienced dental pain was 23.4%. Compared to adolescents who did not report dental pain, adolescents who reported experiencing dental pain were significantly more likely to experience suicidal ideation (OR=1.94, p<0.001). In two multivariate models, the relationships between dental pain and suicidal ideation (AOR=1.24, p<0.001) were statistically significant. Conclusions:Dental pain was associated with increased risk of suicidal ideation among Korean adolescents, even when controlling for sociodemographic factors and other health conditions. It is necessary to consider screening adolescent patients who present with dental pain for suicidal ideation. 연구목적이 연구는 전국 온라인 설문 조사인 2018 청소년 건강 행태 조사의 데이터를 분석하여 청소년의 치통과 자살생각의 연관성을 평가하고자 하였다. 방 법국내 중·고등학생 62,823명을 대상으로 하였으며, 치통과 자살생각을 포함한 건강 행태에 대한 온라인 자가보고형 설문 조사에 60,040명이 참여하였다. 다중 로지스틱 회귀 분석을 시행하여 치통과 자살 생각 사이의 관계를 분석하였다. 결 과자살 생각을 보고한 한국 청소년의 비율은 13.3%이었고, 치통을 경험한 청소년의 비율은 23.4 %였다. 치통을 경험하지 않은 청소년과 비교할 때, 치통을 경험한 청소년이 자살 생각을 경험할 확률이 높았다(OR=1.94, p<0.001). 다중 로지스틱 회귀 모델에서 치통과 자살 생각(AOR=1.24, p<0.001) 의 연관성은 통계적으로 유의하였다. 결 론한국 청소년의 치통은 사회 인구 통계학적 요인 및 기타 신체적 정신적 건강 요인을 고려해도 자살 생각 증가와 연관되었다. 우울감을 동반한 치통환자의 진료에 있어 자살 위험성의 선별검사가 고려되어야 한다.

The radiating multislotted antennas widely used in the antennas technique are rather prospective for the application in industrial installations for microwave heating. In this paper, the model of such an antenna is experimentally investigated. The model under investigation presents a section of the waveguide Inn 340 whose broad wall contains 15 movable slotted plates. This design allows to experimentally define a location of all the slots providing the necessary distribution of radiating power along the waveguide with minimal SWR of all the system. The variants of power uniform distribution along the waveguide as well as the power decreasing to the waveguide end are examined. The application of plates with different thickness allowed to estimate the influence of the walls thickness on the Power distribution. The possibility of system extra-tuning with the help of tuning screws located in the vicinity of each slot is considered. Obtained results are compared to the conducted theoretical calculations and data in references.
