Objectives: This study was performed to grasp the relation between the effect and the satisfaction of mouth gymnastics program on the promotion of oral function of students. We investigate the degree of digestion due to stress and the changes in salivary flow. We should investigate about the relationship of xerostomia according to the changes in salivary secretion. Methods: Total 79 students for two weeks, Silla University Dental Hygiene Department participated in this survey. Results: In the point of view of oral xerostama, people without drinking have lower symptom and action of xerpstama than those who drink three or four times a week. As the change rate of salivation amount is large, the degree of digestion, stress and xerpstama symptom and action is low. However the satisfication of oral exercise program is high. Conclusions: Adult should pay attention to oral health through oral exercise which increases the amount of salivation. Also Oral and total health should be increased through oral health education for the methodical oral health program

이상문학의 동양지향성 : 이상과 이백의 현실초월로서의 '달'을 중심으로

고현혜 이화여자대학교 이화인문과학원 2009 탈경계 인문학 Vol.2 No.1

Up to now, the works of Lee Sang[李箱, a Korean poet and novelist, 1910~1937] have been usually interpreted from Western literary context and viewpoints, and Lee Sang's interests in the Oriental classic literature have been largely overlooked. However, Chinese culture and literary texts were found to be frequently mentioned in Lee Sang's works. This study, paying attention to this point, strives to reveal the East-directed aptitude shown in Lee Sang's literary texts and to link it to his avant-garde spirits. Especially, this study attempts to connect Lee Sang's avant-garde features with Li Bai's[李白, a Chinese poet, 701-762] art and life. Lee Sang creatively transforms Le Bai's poetry that has largely affected Korean classic poetry. For example, Li Bai's 'moon' implies the fresh and ideal meaning and driving force in his life and literature. Lee Sang creatively transforms Li Bai's moon into a "silver coin" which symbolizes "pure spirit" in his novels: in the 「Wing」(1936. 9), "silver coin" represents clear and pure mind, and in 「Chijuwhesi」(1936. 6), "silver coin" is expressed with a sublime sense. Lee Sang's creation of "silver coin" could be estimated as his efforts to create something symbolizing a pure and sublime value which can never be exchanged in the capitalist society of the early modern period.

The purpose of this study was to assess satisfaction of elementary school children and their parents with the school lunch program(SLP). 430(209 male, 221 female) 5th and 6th grade elementary school children and their parents participated. Most joyful mealtime for children was lunch because of eating with friends. Many children leftover their meals because they didn't prefer food served by SLP. Children also thought the taste of meals delivered from home was better than that of meals served by SLP. Many schools provide tap water(14.0%) and underground water(25.6%) , and there were many children who had ever found some foreign subjects in food, plates, or spoons. Mother wanted the school lunch program to be continued and claimed the quality of nutrition of SLP should be improved. In conclusion, unless the children prefer the food served by SLP or adjust to the general aspects of SLP, SLP can't accomplish its purposes. Therefore, the menu for the SLP should be selected with consideration of children's preference and it is necessary to prepare the way to solve the problems concerning general aspects of SLP.

The acid value (AV) as well as the ester value of essential oil is an important index to evaluate quality of essential oil. The official standard analytical method of KS H ISO 1242 dealing with “Essential oils - Determination of acid value” was assessed experimentally using two lavandin essential oils obtained in France as an example. One French lavandin oil sample showed the results of AV= 0.9 by both indicator method and potentiometry. Another sample showed AV = 1.9 by indicator method and AV = 1.6 by potentiometry. Latter lavandin oil sample exhibited significantly higher acid value than maximum value of 1 described in the standard. This result suggests that latter lavandin oil was contaminated, because this oil was contained in an orange juice bottle. Results of this study proved that KS H ISO 1242 could be used as a suitable scientific standard for the determination of acid value of essential oils.

오종현,박세희,신혜진,조경모,김진우 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.2

이 실험의 목적은 Resilon으로 근관충전된 치아에서 자가산부식전처리제에 따른 치근단 미세누출을 평가하고자 함이다. 70개의 단근치를 사응하였고 .04 Taper ProFile을 사용하여 ISO #40까지 근관성형 하였다. 치아는 근관충전 재료와 자가산부식 전처리제에 따라서 15개씩 4개의 실험군과 5개씩 2개의 대조군으로 나누었다. 실험 치아는 치아 장축에 평행하게 잘라내어 염색액의 최대 침투 길이를 측정하였다. 통계분석은 One-way ANOVA test로 분석하였으며 Scheffe test로 사후검정 하였다. 실험결과 자가산부식전처리제를 사용한 2, 3, 4군 사이에서는 통계적으로 유의한 차이를 나타내지 않았다. 그러나 1군과 4군 사이에서는 통계적으로 유의한 차이가 나타났으며 (p < 0.05), 1군에서 가장 적은 치근단 미세누출을 나타냈다. 이 실험 결과에 따르면 Resilon으로 근관충전을 한 치아는 gutta percha와 AH26^(ⓡ)으로 근관충전할 치아와 비교했을 때 더 좋은 치근단 밀폐를 나타내지 않는다는 결론을 얻었으며, Resilon을 사용하여 근관충전을 한 경우에 자가산부식 전처리제의 차이에 따른 치근단 밀폐효과의 차이를 보이지 않는다는 결론을 얻었다. The purpose of this study was to compare the apical microleakage in root canal filled with Resilon by several self-etching primers and methacrylate-based root canal sealer. Seventy single-rooted human teeth were used in this study. The canals were instrumented by a crown-down manner with Gate-Glidden drills and .04 Taper Profile to ISO #40. The teeth were randomly divided into four experimental groups of 15 teeth each according to root canal filling material and self-etching primers and two control groups (positive and negative) of 5 teeth each as follows: group 1 - gutta percha and AH26^(ⓡ) sealer; group 2 - Resilon, RealSeal™ primer and RealSeal™ sealer; group 3 - Resilon, Clearfil SE Bond^(ⓡ) primer and RealSeal™ sealer group 4 - Resilon, AdheSe^(ⓡ) primer and RealSeal™ sealer. Apical leakage was measured by a maximum length of linear dye penetration of roots sectioned longitudinally by diamond disk. Statistical analysis was performed using the One-way ANOVA followed by Scheffe' s test. There were no statistical differences in the mean apical dye penetration among the groups 2, 3 and 4 of self-etching primers. And group 1, 2 and 3 had also no statistical difference in apical dye penetration. But, there was statistical difference between group 1 and 4 (p < 0.05). The group 1 showed the least dye penetration. According to the results of this study, Resilon with self-etching primer was not sealed root canal better than gutta precha with AH26^(ⓡ) at sealing root canals. And there was no significant difference in apical leakage among the three self-etching primers.

Background : Diagnosis of peripheral pulmonary lesion by conventional bronchoscopy is still challenging. The sheathed bronchial brush has been used to collect samples from the visible endobronchial lesion. Recently developed endobronchial ultrsonography (EBUS). can obtain image of peripheral pulmonary lesion at bronchus suspected by bleeding sign of sheathed brush. This study evaluated availibility of detected lesions by bleeding after bronchial brushing in pheripehal pulmonary lesions before transbronchial lung biopsy Methods : Between August 2006 and November 2008, 50 patients(38 men and 12 women, median age, 65 yrs) whose peripheral pulmonary lesions could not be detected with flexible bronchoscopy were included in this study. Among 50 patients, 40 cases were malignant lesion(non-small cell carcinoma 35, small cell carcinoma 5), and 10 cases were benign lesions(inflammatory disease 7, others 3) Results : Of the 50 patients, lesions detected bleeding after bronchial brushing was 34 cases(68%) and lesions detected by EBUS was 33 cases(66%). Sensitivity was 90.0-95.4%, Specificity was 83.3-80%, Positive predictive value(PPV) was 83.3-95.4% and Negative predictive value(NPV) was 80-90.9%. Diagnostic rates in visualized lesion by EBUS and otal peripheral lesions were 75%(25/33), 58%(29/50) respectively. There was no significant complication related with bronchial brushing. Conclusions : Bleeding sign by bronchial brushing was safe and effective method to predict location of peripheral pulmonary lesion with sufficient diagnostic yield

김영순,임지혜,배현주 한국문화교육학회 2011 문화예술교육연구 Vol.6 No.2

The aim of this study was to search conditions activating the regional consortium for regional culture education in schools. Results of this study are follows: the regional consortium consists of parents of students, communities, schools, school boards, public institutes, and NGO groups. The consortium contribute the educational support and development for student activities in schools. Furthermore the consortium make an offer to coordinate and facilitate the delivery of information, resources, and services to students, educators, employers, and the community. Therefore, the consortium might be best described as "matchmakers" that help ensure that our customers are able to easily connect with providers of the services they need. The consortium will be made up of a network of service providers from across its region that all collaborate in helping to connect the local education and school communities. 본 연구에서는 지역 사회의 인적·물적 자산을 활용한 문화적 체험활동 교육이 활성화되고 정착되기 위한 방안으로 학교와 지역사회가 밀접한 관계를 형성할 수 있는 지역협의체를 구성하는 안을 제시하였다. 이를 위해 지역문화교육에 필요한 지역협의체에 대한 문헌연구를 수행하였고, 이와 유사한 실제 사례를 찾아 관련 전문가를 대상으로 한 심층인터뷰 결과를 정리하고 시사점을 도출하였다. 연구결과, 지역협의체는 지역특수성, 전문성, 개방성, 공공성, 지속성의 기본원칙을 전제로 하여 교육행정기관, 지자체 행정기관, 민간 및 공공기관, 학교 등의 협력을 통해 구성될 수 있다. 또한 지역에서의 문화적 체험활동의 효율적인 운영을 지원하기 위해 1) 지역사회 내 교육기부 협력기관을 모색 및 발굴·연계, 2) 지역의 교육 인프라 접근성 향상, 3) 지역의 문화 교육 자원 간 네트워크 확장, 4) 지역 내 긍정적인 담론 형성을 위한 홍보 및 인식 개선, 5) 지역문화교육 프로그램 수행 과정의 성찰 등의 역할을 수행해야 한다. 지역협의체를 통한 학교와 지역교육자원의 연계 방안은 교육자원의 유형과 교육운영 주체에 따라 분류될 수 있었고, 강동구청과 대구광역시교육청의 예를 통해 지역문화교육 지원의 구체적인 사례를 살펴볼 수 있었다. 이와 같이 본 연구에서 제안한 지역협의체의 구성은 지역문화교육의 활성화를 위한 초석을 마련해 줄 것이라고 기대해 본다.
