본 연구는 자신들의 일상 공간에 대한 교육대학교 학생들의 답사 활동에서 나타난 지리 교육적 함의를 고찰한 것이다. 답사 활동에 대한 관찰 결과, 교육대학교 학생들은 자료 수집의 방법으로서 설문지와 면담에 대한 의존도가 높았으며, 수집된 정보를 시각 공간 자료로 변환하거나 가공하는 데 다소 미숙하였다. 그렇지만 교육대학교 학생들은 자신들의 답사 활동 경험이나 결과를 장차 초등 지리 교육에 적극적으로 활용하거나 응용하고자 하였다. 이는 교육대학교 학생들의 학습 활동이나 과제 활동에서 나타나는, 이른바 초등 예비 교사로서의 독특한 행동 정향(定向)의 하나로 주목된다. 답사 활동에 대한 자기 및 동료 평가의 결과, 일상 공간에 대한 답사 활동이 지니는 지리 교육적 가치를 분명히 인식한 유의미한 경험이었다는 점, 자신들의 일상 공간에 대한 관심을 높이고 그 의미를 반추할 기회가 되었다는 점, 나아가 긍정적인 장소감을 내면화하고 장소 정체성을 공고히 하는 계기가 되었다는 점 등을 확인할 수 있었다. 이러한 연구 결과는 교육대학교 지리 교육과정에서 답사 방법론 내용을 더욱 체계화할 필요가 있다는 점을 함의한다.

Purpose: This study was conducted to design and implement a fundamental nursing practice based on flipped learning and to examine the effects. Methods: Participants were 57 students who were taking the fundamental nursing practice course at D university in N city. The study included processes of instructional design, action/effects and reflection. Data were analyzed using paired t-test with the SPSS/WIN 23.0. Results: In the instructional design stage, the class consisted of 3 parts: outside class (pre-learning), inside class (assessment, collaborative practice, peer review, reflection), after-class (self-directed practice, feedback). In the action/effects stage, the flipped learning was applied for 15 weeks according to the instructional design and then the effects of flipped learning were evaluated. Students showed a significant improvement in self-directed learning ability (t=-3.56, p=.001) and critical thinking disposition after the class (t=-3.72, p<.001). Finally, in the reflection stage, the researchers examined whether the four pillars of flipped learning occurred. Conclusion: Findings indicate that flipped learning applied in fundamental nursing practice is effective in improving self-directed learning ability and critical thinking disposition. The action research method was a useful way to foster professor's educational competency as well as to verify effects of a new nursing education method.

Objective: The aims of our study were to verify the validity of the T-Scan III system (Tekscan) as an objective occlusal evaluation tool, and to assess the differences between two occlusal indexes - the peer assessment rating (PAR) index and the American Board of Orthodontics objective grading system (OGS) - by comparing the scores derived from the T-Scan III system with the two occlusal indexes and analyzing the correlations between them. Methods: The final study sample included 48 adult volunteers (39 men and 9 women, mean age $24.14{\pm}3.16years$), after excluding 29 volunteers whose occlusion could not be evaluated by the T-Scan III system due to severe skeletal or occlusal problems. PAR index and OGS scores were assessed using dental study models, and measurements of centric occlusion, protrusive movement, and lateral excursion movement were obtained via the T-Scan III system. The results were analyzed to determine correlations. Results: Occlusal analysis by the T-Scan III system was clinically reliable (p < 0.05), and the PAR index and OGS scores were significantly correlated with several measurements obtained with the T-Scan III system (p < 0.05). Conclusions: The T-Scan III system is a quantitative and reliable method for occlusal evaluation, and represents a potential substitute for occlusal indexes. Compared to the PAR index, the OGS scores of more variables were significantly correlated with the T-Scan measurements.

Background: Hearing loss is one of the most prevalent worker health conditions worldwide. Although the effect of noise exposure on hearing is well researched, other workplace exposures may account for significant hearing loss. The aim of this review was to determine whether occupational hand-arm vibration exposure through use of power or pneumatic tools, independent of noise exposure, is associated with permanent hearing loss. Do workers suffer from hand-arm vibratione-induced hearing loss? Methods: Peer-reviewed articles published in English between 1981 and 2020 were identified through five online databases with five search keywords. Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, including online database search methodology, study selection, article exclusion, and assessment of potential study design confounders and biases, were followed. Results: Database searches retrieved 697 articles. Fifteen articles that reported 17 studies met the criteria for review. All but two studies revealed statistically significant associations between occupational exposure to hand-arm vibration and hearing loss. The majority of the study results revealed associations between hand-arm vibration and hearing loss, independent of potential age and noise confounders. Conclusion: Few studies have examined the association between occupational exposure to hand-arm vibration and hearing loss. Dose response data were limited as only one study measured vibration intensity and duration. Although the majority of studies identified statistically significant associations, causal relationships could not be determined. Further research using standardized and uniform measurement protocols is needed to confirm whether the association between occupational exposure to hand-arm vibration and permanent hearing loss is causal and the mechanism(s).

Purpose: The purpose of this study was to survey the current status of mental health education and need for mental health education enhancing protective factors in the elementary schools. Methods: We surveyed 10 school health teachers and 328 fifth- and sixth-grade students using 19- and 20-item questionnaires, respectively. Results: All of the teachers and 65.2% of the students replied that they were either teaching or being taught mental health in school. Topics covered suicide, depression, school violence, and Internet addiction. All of the teachers and 84.1% of the students expressed the need for mental health education enhancing protective factors in school. Both groups replied that two sessions are enough. The teachers preferred role play and discussion as teaching methods, and audiovisual materials and computer as instructional media. The students preferred lecture and role play as teaching methods, and audiovisual materials and smartphone as instructional media. Both groups ranked self-esteem, parent-child relationship, peer relationship, and emotional regulation as the most important topics to be covered in the education. Conclusion: There is a high demand for mental health education enhancing protective factors. Therefore, it is recommended to develop educational programs enhancing protective factors by enabling formal and informal learning using smartphone.

Pesticides have provided significant benefits including plant disease control and increased crop yields since people developed and utilized them. However, pesticide use is associated with many adverse effects, which necessitate precise toxicological tests and risk assessment. Most of these methods are based on animal studies, but considerations of animal welfare and ethics require the development of alternative methods for the evaluation of pesticide toxicity. Although the usage of laboratory animals is inevitable in scientific evaluation and alternative approaches have limitations in the whole coverage, continuous effort is necessary to minimize animal use and to develop reliable alternative tests for pesticide evaluation. This review discusses alternative approaches for pesticide toxicity tests and hazard evaluation that have been used in peer-reviewed reports and could be applied in future studies based on the critical animal research principles of reduction, replacement, and refinement.
