The purpose of this study is to investigate fluoride release in the oral cavity from polymer adhesive tape which is NaF coated PVA. 45 healthy adults were divided into 3 groups by the type of topical fluoride applied: 60seconds taste$^{(R)}$ APF gel (group 1), FluoroDose$^{(R)}$ varnish (group 2) and NaF-PVA (group 3). Topical fluoride was applied to the facial surface of maxillary 12 teeth and unstimulated whole saliva was collected to measure fluoride release after 1, 3, 6, 12, 24, and 48 hours. Fluoride-sensitive electrode was used for measuring the fluoride concentration in the saliva samples. All three groups showed significantly higher value for fluoride concentration than the baseline after 1 and 3 hours (p < 0.05). After 6 hours, group 3 showed significantly higher fluoride concentration than the baseline (p < 0.05) and also showed significantly higher value for fluoride concentration than group 1 and group 2. Between group 1 and group 2, however, there was no significant difference statistically with respect to fluoride concentration value (p > 0.05). 연구의 목적은 인체 안정성이 입증된 고분자제제인 폴리비닐알코올(PVA, polyvinyl alcohol)로 얇은 박막을 제조하고 불화나트륨(NaF)을 첨가하여 불소를 함유한 고분자 접착 테이프(NaF-PVA)를 개발하여 피실험자의 구강 내에 도포 후 잔류하는 불소농도를 측정하였다. 이를 통해 제제 도포 전후의 타액 내 불소농도를 분석하여 불소를 함유한 고분자 접착 테이프의 치아우식증 예방효과를 간접적으로 평가하였다. 불소겔(60seconds taste$^{(R)}$, Group 1), 불소바니쉬(FluoroDose$^{(R)}$ varnish, Group 2)와 불소를 함유한 고분자 접착 테이프(NaF-PVA, Tiral product, Group 3)를 각각 15명씩 상악 치아 12개의 순면에 도포 후, 1시간, 3시간, 6시간, 12시간, 24시간, 48시간 후 비자극성 타액 내 불소농도를 불소이온전극을 이용하여 측정하였다. 도포 후 3시간까지 세 군 모두 불소제제 도포 전 농도보다 유의하게 높은 불소농도를 보였으며 3군의 경우 도포 후 6시간에서도 불소제제 도포 전 농도보다 유의하게 높은 불소농도를 보였다(p < 0.05). 도포 후 6시간에서 3군은 1군과 2군보다 유의하게 높은 불소농도를 보였고 (p < 0.05), 1군과 2군 사이의 유의한 차이는 없었다(p > 0.05).

심한 우식을 보이는 미성숙 영구치 치료에 있어서 치수생활력을 보존하는 것은 중요하다. 치수절단술을 시행 시 생체적합성이 있는 재료를 이용하여 치료함으로써 남아있는 생활력이 있는 치수를 보호하며 미성숙 영구치의 치근 성장을 도모할 수 있다. 혈소판 농축 섬유소는 환자의 혈액을 직접 채취하여 적용하기 때문에 생체적합성이 뛰어나며 다양한 성장인자를 함유하고 있어 치수생활력을 유지하고 미성숙 영구치의 치근 발육을 촉진시킬 수 있다. 본 증례에서는 심한 치아 우식증을 보이는 미성숙 영구치에서 치수절단술 시행 후 남아 있는 치수 상부에 혈소판 농축 섬유소를 적용하였다. 정기적인 검진 결과 미성숙 영구치의 치근 성장 및 정상적인 치아 주위 조직들이 관찰되었다. 향후 장기간의 임상적 관찰이 필요할 것이며 더 많은 임상 증례를 바탕으로 한 연구가 필요할 것이다. Preserving the pulp is important in the treatment of carious pulp exposure in young permanent teeth. Pulpotomy is a vital pulp therapy in which a portion of the coronal pulp tissue is surgically removed, and the remaining radicular tissue is covered with suitable material that protects the pulp from further injury and permits and promotes healing. It is important to develop biocompatible treatment directed at maintaining pulp vitality and increasing tooth longevity. Platelet-rich fibrin (PRF) has been referred to as a second-generation platelet concentrate. Two clinical cases in which PRF was applied as a medicament after pulpotomy of an immature permanent tooth are presented. After isolation, caries removal and pulpotomy with PRF was performed. A layer of mineral trioxide aggregate (MTA) was placed over the PRF, and the final restoration was performed. Postoperatively, the patient had no pain or discomfort, and follow-up radiographs revealed normal periodontal ligament space and trabecular bone pattern.

Purpose : This study investigates pediatric nurses' knowledge and attitudes regarding iatrogenic narcotic analgesic withdrawal symptoms management (INAWSM). Methods : In this cross-sectional study, 253 pediatric nurses working at a tertiary hospital in Seoul participated. Instruments were the inventory consisting questionnaires on 35 items knowledge and 12 items attitude for INAWSM. Further, descriptive statistics, t-test, and analysis of variance were used to evaluate the nurses' knowledge and attitudes. Results : The correct answers rate of knowledge toward INAWSM was 44.9%. With respect to the pediatric nurses' attitudes, the participants scored an average value of $2.83{\pm}0.25$ out of 4 points. The factor related to the knowledge and attitude level was age, pediatric nursing experience, educational experience, and educational needs. Conclusions : Results revealed that pediatric nurses had inadequate knowledge and attitude on INAWSM despite a compulsory education. Therefore, it is necessary to develop an efficient INAWSM educational program.

Injury to young permanent teeth occurs frequently in children and adolescents following orofacial trauma. In traumatized immature teeth with pulp exposure, preservation of pulp vitality is important. Mineral trioxide aggregate (MTA), as a pulp capping agent that promotes root development and apical closure, has recently gained attention due to its favorable physical and biological properties. In this a d e, we report two cases of traumatized maxillary central incisors that were treated with MTA following direct pulp capping.

연구배경: 단면적 연구들에서 자녀의 체중감량을 위한 부모의 개입과 자녀의 체중간에는 부정적 관련성이 있었다. 전향적 코호트 연구로 부모의 감량 시도가 자녀의 2년 후 체질량지수 및 체중 관련 태도에 미치는 영향을 알아보았다. 방법: 2001년에 부산시에 소재한 5개 초등학교의 422명의 11-12세 학생들과 그들의 부모가 연구대상 이었다. 설문지로 부모들의 자녀 체중 감량 시도 유무를 포함한 부모의 특성을 조사하였고, 2년 후에 자녀들에게 설문지로 체중 관련 태도(체형 불만족, 식사태도, 감량시도)에 관하여 조사하였다. 11~12세에 측정한 자녀들의 체중과 신장 자료를 이용하여 International Obesity Task Force 지침에 따라 남녀 과체중군 및 남녀 비과체중군으로 구분하였다. 결과: 22.5%의 부모들이 자녀에게 체중 감량을 시도 하였고, 부모가 감량을 시도한 자녀의 65%가 과체중군에 포함되었다. 남자 과체중군에 비하여 여자 과체중군에서 2년 후 더욱 마른 체형을 선호하였으며(P<0.05), 식사태도는 남녀 과체중 군 간에 유의한 차이가 없었다. 남자 과체중군에서만 부모가 자녀의 체중 감량을 시도한 자녀에서 시도하지 않은 자녀에 비하여 초기 체질량지수가 유의하게 컸으며 (P<0.05) 2년 후 체질량지수, 2년간 체질량지수 변화량, 2년 후 체중 관련 태도는 남녀 과체중군 모두에서 감량 시도 유무와 관련성이 없었다. 결론: 단면적 연구들과 다르게 부모의 자녀 체중 감량 시도는 초기 청소년 연령의 자녀에서 2년 후 체질량지수 및 2년간 체질량지수 변화량, 체중 관련 태도에 영향을 주지 않는 것 같다. Background: Cross-sectional studies have shown negative relationship between parent`s eating restriction for their child and child`s adiposity. This prospective cohort study examined the relationships between parents` control over adolescent`s weight at the ages of 11~12 with adolescent`s BMI and weight-related attitudes 2 years Later. Methods: 422 parents and their children at the ages of 11~12 years in 2001 from 5 elementary schools, Busan, participated in this study. Parents completed a survey about their control over their child`s weight and children answered to questionnaire about weight-related attitudes (body dissatisfaction, eating attitude, and attempt to diet) 2 years later. children weights and heights were measured at the ages of 11~12 years and 2 years Later. Boys or girls` weight status at baseline was classified into overweight and non-overweight by International Obesity Task Force guideline. Results: Twenty three percent of parents tried to Lose their children weight. Sixty five percent of children who were controlled over their weight by their parents were overweight at baseline. Whereas overweight girls were more Likely to favor slender body shape compared to overweight boys (P<0.05), there was no difference in eating attitude between overweight boys and girls. Although in overweight boys, those who were controlled over weight by parents had greater BMI at baseline than those who were not controlled by parents (P<0.05), there were no differences in boys or girls` BMI after 2 years, BMI difference over 2 years, and weight-related attitudes after 2 years according to parent`s control over child`s weight. Conclusions: This prospective cohort study suggests parental control over child`s weight may not influence on BMI and weight-related attitudes after 2years in boys or girls in early adolescent period.

바흐 모테트의 역사 속으로: 전통과 새로움의 또 다른 얼굴

이가영 ( Ka Young Lee ) 한국음악학학회 2009 음악학 Vol.17 No.-

Bach`s German motet has not yet received scholarly attention in the Korean musicological scene. Part of the reasons of being neglected by scholars has to do with the fact that the genre, the motet, has not been recognised as one of the representative genres written by Bach. This paper discusses Bach`s German motet in terms of the genre, proposing that it was one of the most significant genres that allows the composer to explore the intriguing and intricate interplay between the musical tradition that he inherited and the musical experiment that he newly implemented. After analyzing Bach`s motet, this paper argues that Bach`s motet reflects the musical as well as textual conventions of the time. But, at the same time, this paper also illustrates various ways in which Bach responds to the conventions, thereby creating works that are both traditional and inventive.

바흐 작품의 전통적 해석에 대한 재고: <푀부스와 판의 대결>을 중심으로

이가영 ( Ka Young Lee ) 세계음악학회 2010 음악과 문화 Vol.22 No.-

Johann Sebastian Bach`s <Der Streit zwischen Phoebus und Pan> has long been considered to be a work that delivers both sophisticated and serious musical style and light, pleasurable one. Furthermore, it has been argued that Bach makes a musical comment on both styles, implicitly expressing his own preference to the former. Smusic even makes a strong statement that Phoebus of the work whose music is associated with the serious represents the composer. The aim of this study is to explore the extant to which this perspective tells us about the true nature of the composition. By analyzing the text and music of the work, this study illustrates various ways in which Bach, not necessarily being judgemental, combines one style from another, often creating an ironic statement about each musical style. After examining the text and the music, this study proposes that <Der Streit zwischen Phoebus und Pan> does not attempt to comment on the musical styles available during the period in which Bach lived and worked. Instead, this study argues that what Bach wishes to achieve in this work is to engage his audience into the musical discourse that he creates, thereby directly communicating them through his composition. Bach`s involvement with the Collegium musicum of 1730s allows him to fulfill this purpose.

Hypermagnesemia is a rare condition that is usually iatrogenic in patients with elderly or renal failure. Severe hypermagnesemia is uncommon in patients with a normal renal function. Symptoms due to hypermagnesemia can range from mild symptoms, such as nausea, to severe symptoms, such as cardiac and respiratory arrest. This paper describes a case of a 49-year-old woman who ingested a magnesium-containing fertilizer with normal renal function. Cardiac arrest occurred eight hours after poisoning. Electrocardiography changed from a narrow QRS to a wide QRS and then to a complete atrioventricular block. Her hemodynamic state was unstable. Continuous renal replacement therapy was performed to remove magnesium from the blood, with the subsequent resolution of arrhythmia and hemodynamic stabilization. This paper reviews the pathophysiologic effects of magnesium on the cardiovascular system, clinical manifestation, and treatment of hypermagnesemia.
