The objective of this study is to examine a releasable asbestos sampler developed for measuring friable asbestos from soil to air controlled by wind velocity and water contents. Asbestos contaminated soil with 3.75% at the Sinsuk-asbestos mine was sampled, air-dried and sieved to 100 mesh, then homogenized during 24 hours' agitation. Various wind velocities, 1 m/s, 2 m/s, 3 m/s, and 5 m/s, were applied to evaluate releasable characteristics of the releasable asbestos sampler. In addition, soils with 1.0%, 3.4%, 4.4%, 11.0%, 16.2%, and 20.0% of water contents were also examined the amount of friable asbestos by the releasable asbestos sampler. Collected soil and air samples were analyzed by polarized light microscopy (PLM) and phase contrast microscopy (PCM), respectively. Those contents were applied to calculate an excess life cancer risk (ELCR). This study also discussed the relationship with risk assessment by a weeding scenario of activity based sampling (ABS) and field applied releasable asbestos sampler. The result was shown that friability of asbestos in soil increased with wind velocity and decreased with water content. In comparison with ELCR results, over 10E-4 of cancer risk was found in condition on < 5% water content and > 3m/s wind velocity.

Objectives: This study aimed to confirm the association between cognitive function and oral health status in the elderly. Methods: In this study, 5,794 respondents, aged 55 or older, who had participated in the 7th aging research panel survey were used. Statistical analyses were performed using a complex samples cross-tabulation analysis, complex samples general linear model, and a complex sample multinomial logistic regression analysis. Results: After analyzing the cognitive function of the elderly according to their oral health conditions, it was found that suspicions of dementia (19.6%) and cognitive function decline (25.9%) were more common for those who wore dentures than for those who did not wear dentures (p<0.001). Compared to those who did not wear dentures, those who wore dentures were linked to a 1.665 times higher suspicion of dementia (p<0.001). In comparison, cognitive decline was 0.964 times lower when the number of natural teeth increased by 1, and it was 0.941 times lower when the oral health evaluation index for the elderly increased by 1 point (p<0.001). Conclusions: As a result of this study, it was confirmed that cognitive function and oral health status are related in the elderly. Therefore, systematic measures for oral health management and oral health promotion should be prepared in tandem with awareness of possible cognitive decline in the elderly.

간호학과 졸업생들의 간호교육 성과 측정 도구를 규명하기 위하여 시행한 본 연구에서는 의사소통, 전문직관, 지도력, 비판적 사고를 측정하는 도구들을 탐색하여 타당도와 신뢰도를 규명하였다. 의사소통 능력을 측정한 지지적 의사소통 능력 측정 도구의 경우 신뢰도가 Cronbach’s=.78로 비교적 신뢰도가 좋은 것으로 나타났다. 또한 타당도에서는 수렴타당도로 본의사소통 능력과의 상관계수가 .24 (p<.001), 구성타당도로 본집단타당도에서는 다른 학년에 비하여 4학년의 평균점수가 유의하게 높아 의사소통을 측정하는 도구로 활용할 가치가 있다고 판단하였다. 아직 이 도구를 사용한 논문을 찾을 수 없었으나 대인관계를 손상시키지 않으면서 정확하고 정직하게 의사를 전달하면서, 문제를 해결하는 동안 의사소통하는 사람간의 긍정적인 관계를 보존하는 것을 측정하는(Whetten & Cameron, (1998) 본 도구는 인간관계를 중요시하는 간호학의 전인적 간호를 증진시키는 특징이 포함되어 있어 간호학 교육 성과를 측정하는 도구로 활용할 가치가 있다. 또한 수렴타당도를 측정하기 위하여 선택한 의사소통 측정도구보다 문항수가 적어 효율성도 높다. 지금까지 간호학생을 대상으로 의사소통을 측정한 연구들도 면접을 통한 질적인 자료로 측정하거나(LeBlanc et al., 2009), 연구자들이 개발한 도구(Rosenzweig et al., 2008; Yoo & Yoo, 2001)로 측정하고 있어 효율적이면서 객관적인 도구로써 유용할 것으로 생각한다.전문직관은 신뢰도가 Cronbach’s a=.87로 매우 높게 나타났다. 수렴타당도로 본 Yeun 등(2005)이 개발한 간호전문직관과의 상관계수도 .23으로 유의하였고, 구성타당도를 보기위한 집단 비교법에서는 4학년의 점수가 가장 높았으나 유의하게 차이가 있는 학년은 2학년으로 나타나 간호학 교육 성과도구로 채택하는데 큰 문제가 없는 것으로 판단하였다. 항목이 19개로 구성되어 있어 효율성 측면에서 볼 때 Yeun 등(2005)의 도구보다 활용성이 높다. 특히 주위 다른 사람들과 비교하여 자신의 태도를 측정하고 있어 일반적인 간호사에 대한 의견을 묻는 Yeun등(2005)의 도구에 비하여 개인적인 전문직관을 더 민감하게 측정할 것으로 생각한다. 지도력은 신뢰도가 Cronbach’s α=.94로 가장 높았으며 수렴타당도로 본 지도력 도구와의 상관계수도 .16으로 통계적으로 유의하였다. 구성타당도로 본 집단비교에서는 4학년의 점수가 가장 높았으나 유의한 차이가 있는 학년은 2학년이었다. 문항수가 40문항으로 다소 긴 편이어서 효율성이 떨어지기는 하나 간호 실무에서 4년제 학부 학생의 지도력 특성을 측정하기 위해 개발된 도구라는 점에서 활용할 가치가 있다. 비판적 사고를 측정하기 위하여 선택한 Yoon (2004)의 도구는 신뢰도가 Cronbach’s α=.87로 상당히 높은 편이고, 집단비교법에서도 4학년이 다른 학년에 비하여 유의하게 높아 구성타당도도 만족할 만한 수준이었다. 그런데 본 연구자들이 개발한 비판적 사고 기술 도구와의 상관관계가 유의하지 않아 수렴 타당도가 인정되지 않았다. 이는 몇 가지로 해석할 수 있는데 첫째는 비판적 사고 기술과 비판적 사고 성향이 다를 수 있다는 것이다. 즉 Yoon (2004)의 도구는 비판적 사고 성향을 측정하는 도구이고 연구자들이 개발한 도구는 비판적 사고 기술을 측정하는 도구이기 때문이었던 것으로 보인다, 이러한 해석은 비판적 사고 기술과 사고 성향 간에는 유의한 상관관계가 없다는연구 결과가 뒷받침한다(Raymond, Rachel, & Jenny, 2002). 그러나 두 개념간에 상관관계가 있다는 연구결과도 있어(Profetto-Mcgrath, 2003) 이 두 개념 간의 관계에 대한 심층적인 연구가 더 필요하다. 두 번째는 비판적 사고 성향을 측정하는 Yoon (2004)의 도구는 정답이 존재하지 않으나 비판적 사고 기술을 측정하는 도구는 정답이 있는 도구인데 자료를 수집할때 이를 설명하지 않고 측정하여 두 도구의 상관관계가 없는 것으로 나올 가능성도 배제할 수 없다. 성향을 측정하는 것과 달리 정답이 있다고 하는 경우는 본인의 생각과 다르더라도 비판적 사고 기술에 해당하는 내용을 선택할 수 있으나 정답이 없다고 생각하는 경우는 설령 비판적 사고 기술에 해당하는 내용이라고 판단하더라도 본인의 성향과는 다르기 때문에 다른 내용을 선택할 수 있기 때문이다. 또한 성향과 기술이라는 특성이 다른 측면을 측정하는 과정에서 성향은 Likert 척도로 기술은 이분법으로 측정한 것도 상관관계를 떨어뜨린 이유로 보인다. 세 번째는 Yoon (2004)의 도구는 이미 몇 연구에서 사용하여 왔으나 아직도 더 검증이 필요하고, 본 연구자들이 개발한 도구도 신뢰도가 낮아 신뢰도와 타당도를 높이기 위한 작업이 더 필요함을 나타낸다고도 볼 수 있다. 현재 가장 많이 사용하는 도구인 Facione과 Facione (1994)이 개발한 California Critical Thinking Disposition Inventory (CCTDI)를 활용하는 방법도 있으나 75문항으로 긴 편이어서 효율성이 떨어지고 사용하기 위하여 많은 비용을 지불하여야 하므로 비경제적인 측면이 있다. 결론적으로 본 연구에서 규명한 네 도구는 신뢰도와 타당도가 비교적 높게 나타나 간호교육기관에서 사용할 수 있을 것으로 판단하였다. 비판적 사고 측정 도구는 수렴 타당도가 낮게 나와 비판적 기술과 성향을 구분하여 측정하여야 한다고 판단하였다. Purpose: The purpose of this study was to identify and evaluate outcome measurement scales of nursing education such as communication, professionalism, leadership, and critical thinking. Methods: A methodological study design was used to evaluate the reliability and validity of the scales. Survey was done to the students (n=407) enrolled in baccalaureate nursing schools. Using convenience sampling method, we tried to include all grades of students. Internal consistency, convergent validity and group comparison were used to evaluate the reliability and validity of the scales. Results: All scales were reliable and valid. Only convergent validity of the scale to measure critical thinking was relatively low. It suggested that critical thinking skill and disposition might be measured separately. Also it was inefficient to measure the nursing education outcomes with separate scales. Conclusions: It is recommended to develop a new integrative scale to measure nursing education outcomes. Also it is necessary to set the norm of nursing students to evaluate nursing education outcomes for the quality control of nursing education.

Objectives: The objective of this study was to analyze dental caries incidence in the permanent teeth of 12-year-old children. Methods: This study used the raw data from the 2015 Korean children’s oral health survey. Participants of the research were 12-year-old children in their first year of middle school. A total of 27,291 people participated in the questionnaire and oral examination. Statistical analysis was performed using complex samples frequency analysis and contingency coefficient phi (φ). Results: Dental caries predominately developed symmetrically with a higher tendency for left-right symmetry than for maxillary-mandibular symmetry in the mouth. The incidence of dental caries between adjacent teeth had a statistically significant correlation and was highest in the first and second premolars. Conclusions: Information on symmetry in the development of dental caries and the association of dental caries incidence between adjacent teeth of 12-year-old children should be actively utilized when establishing evidence-based dental caries management plans.

Objective : Herb medicines are potential sources of useful edible and medicinal plants. They are used as a drug because of their various biological activities such as immunomodulatory, antiviral, and antitumor functions. Nelumbo nucifera have been applied in Chinese herbal prescriptions to improve tissue inflammation. However, it has not been elucidated on the effect of the flower of Nelumbo nucifera in cells. Method : In the present study, to examine the effect of that on glioma cells, U87, the essential oil was extracted from the flower of Nelumbo nucifera (NN essential oil). U87 cells were exposed to different concentrations of 2-40 ug/ml of NN essential oil in ethanol. Cell viability was measured by MTT assay at 24 h. To find out the intracellular target signal molecule(s) for this antiproliferative activity of NN essential oil, phosphorylation of Akt, ERM, MAPK or p38 proteins were examined by Western blot analysis. To study long term effect of NN essential oil in U87 cells, the image of cells treated with NN essential oil for 4 days were obtained. Results and Conclusion :. NN essential oil was shown to exhibit antitumor activity in glioma cells, at a broad range of concentrations of 10-40 ug/ml. The phosphorylation of Akt and Endoplasmic Reticulum Matrix (ERM) proteins which known to be involved in the cell death, were gradually decreased to 2 hours after addition 20 ug/ml of NN essential oil. However, the phosphorylation of mitogen-activated protein (MAPK) and p38 was found to increase in NN essential oil treated cells. NN essential oil treated cells showed decreased glioma cell number. These results provide a possible NN essential oil-induced inhibitory signal for tumor cell proliferation that is initiated by the decrease in Akt activity. Moreover, it is likely that the activation of p38 is required for the NN essential oil-induced inhibition of tumor proliferation.

Objectives: The purpose of this study was to analyze the patterns of dental caries experience on the tooth surface of Korean adolescents of the ages of 12 and 15 years. Methods: The raw data from the 2012 Korean National Oral Health Survey were reviewed, and the records of a total of 10,542 adolescents were analyzed in this study. The surfaces of the 28 permanent teeth were categorized into the occlusal, smooth, and proximal surface types. Descriptive statistics, correlation analysis, multidimensional scaling analysis, and cluster analysis were performed to analyze the data. Results: The analysis of the relationship of the dental caries experience on the tooth surfaces between the oral quadrants revealed that the correlation between the surface relationship of the left and right teeth was higher than that between the upper and lower teeth, in all of the quadrants. As a result of multidimensional scling analysis, the adolescents aged 12 were classified into six clusters: occlusal surface of mandibular first molars, occlusal surface of maxillary first molars, smooth surface of maxillary first molars, smooth surface of mandibular first molars, occlusal surface of mandibular second molars and the rest of tooth surface. Similarly, the dental surfaces of the 15-year-old adolescents were classified into seven clusters: occlusal surface of the mandibular first molars, occlusal surface of the maxillary first molars, smooth surface of the first molars, occlusal surface of the mandibular second molars, occlusal surface of the maxillary second molars, smooth surface of the mandibular second molars, and the surfaces of the. The patterns of caries experience are usually clustered on the same types of tooth surfaces; for example, patterns on an occlusal surface clustered with those on another occlusal surface, or patterns on a smooth surface with those on another smooth surface. Conclusions: Knowledge about the caries patterns on the tooth surfaces might be useful for the prevention and management of dental caries.

Objectives: The purpose of this study was to examine the knowledge of elementary school teachers regarding first aid for maxillofacial trauma and the need for education on this topic in an effort to provide information for the development of teacher education programs. Methods: In this cross-sectional study, 320 elementary school teachers who visited the Education and Training Center of Jeollabukdo to take training courses answered a self-administered survey. Results: We found that 38.8 percent of the elementary school teachers had witnessed the occurrence of maxillofacial trauma in students. While 53.4 percent of the teachers replied that they did not have adequate knowledge of first aid for maxillofacial trauma, only 10.7 percent reported receiving this education while they served as teachers or when they were studying to be teachers at college. The teachers who had received instruction for dealing with maxillofacial trauma as teachers or as college students were 3.6-fold more likely to report that they would provide first aid for maxillofacial trauma compared with those who had not received such training. Many teachers had incorrect knowledge about how to cope with this type of trauma, indicating the need for providing correct information to this population. Finally, 99.1 percent of the elementary school teachers considered receiving education about first aid for maxillofacial trauma necessary. Conclusions: The development of teacher education programs is required to help elementary school teachers offer appropriate first aid when maxillofacial trauma occurs.

본 연구는 치위생(학)과 학생 450명을 대상으로 성격 5요인과 대학생활 적응관계를 알아보기 위한 연구이다. 자료수집은 2017년 06월 27일부터 08월 31일까지 진행하였고 수집된 자료는 SPSS 23.0 프로그램을 이용하여 일원배치분산분석, 신뢰도 분석, 상관분석, 다중회귀분석을 통하여 분석하였다. 연구결과 대학생활 적응도는 2학년 학생들이 사회적 적응, 정서적 적응, 신체적 적응, 대학에 대한 애착 적응이 높았다. 성격특성과 대학생활 적응 상관성에서 신경증의 성격은 대학생활에 대한 적응도가 낮았으며, 외향성, 개방성, 친화성, 성실성의 성격이 대학생활에 대한 적응도가 높았다. 학교생활 적응도에 영향을 미치는 성격특성 및 학년에 따른 성격특성이 대학생활 적응 정도에서 신경증적 성향은 부정적인 정서적 적응을 하였으며, 학년별 성격특성에서도 신경증적 성향의 1, 2, 3학년 학생은 부정적인 정서적 적응을 하였다. 연구결과 치위생(학)과 학생의 대학생활 적응을 높이기 위해 다양한 성격의 특성을 파악할 필요성이 있으며 신경성 성격을 지닌 학생들을 위한 학생들을 학교에 적응할 수 있도록 노력하며, 각각 성격에 맞는 구체적인 대학생활적응 프로그램 개발 및 성격특성에 맞는 연구가 필요하다. This study sought to research five personality factors of 450 dental hygiene students and their ability to adapt to a college environment. Data were collected from June 27th~August 31st, 2017, and the one-way analysis of variance, confidence analysis, correlation analysis, and multiple regression analysis was carried out using the SPSS 23.0 program. The results show that sophomores have high social, emotional, physical, and attachment adaptation to college. In the correlation between personality characteristics and college life adaptation, students with neurotic personalities have low college adaptation, but those with extroversion, openness, sociability, and sincerity have high college adaptation. In the effects of personality characteristics on college adaptation and the college life adaptation level of each grade"s personality characteristics, the neurotic tendency has negative emotional adaptation, and freshmen, sophomores, and juniors with neurotic personalities have negative emotional adaptation as well. These results indicate that it is necessary to comprehend various personality characteristics to enhance the college adaptation of students, to help students with a neurotic personality to adapt to their college life, to develop specific college adaptation programs for each personality type, and to conduct research according to personality characteristics.
