비정상 맹출로와 치근 만곡을 지닌 매복 상악영구전치의 자가치아이식 치험례

매복치의 치료는 그 발생원인,치아의 발육단계,매복된 위치 및 맹출 경로,환자의 협조도 등을 고려하여 치료방법을 결정 한다. 일반적으로 맹출에 영향을 줄 수 있는 유전적,전신적 유발인자가 있다면 이의 치료와 더불어 맹출 유도를 위한 조기치료의 필요성이 있으며,맹출에 장애를 주는 물리적 요소가 존재한다면 이를 우선적으로 제거해야 한다. 그러나 맹출과 관련된 어떠한 요인이나 맹출공간 부족 등이 발견되지 않았다면 유치 발거 이외에 치아를 외과적으로 노출시킨 후 교정장치를 부착하고 교정력을 이용하는 치아맹출 유도법,그리고 매복치를 외과적 재위치 또는 이식하는 방법을 사용할 수 있다. 자가치아이식술을 시행할 경우 치아발육 상태를 고려한 적절한 시기의 선택,적절한 치조와 형성 빛 이식치아의 발거와 식립에 있어 외상의 최소화등이 성공에 중요한 요소다. 본 증례에서는 상악우측중절치의 미맹출을 주소로 내원한 7세 여자 환자에서 CT검사결과 상악우측중절치의 치관부가 전 비극에 근접하여 협측으로 위치되어 있으며 치관부에서 만곡이 관찰되었다. 치근은 Nolla's stage 7정도의 발육을 보였으며 이에 자가치아이식을 시행하였다. 주기적인 관찰결과 치근흡수 등의 합병증 없이 양호한 치유양상이 관찰되었다. In the case of the impacted teeth, the clinician has to consider development of tooth, site of impaction, eruption path, and cooperation of patient, If there are genetic or general factors to effect the eruption of tooth, the clinician treats these first and then takes the early treatment for eruption guidance, If there are physical factors to intercept eruption, the clinician put them off first. However. if there are no factors to effect eruption of tooth and enough space for eruption, the clinician can consider extraction of deciduous teeth, forced eruption and surgical reposition. In case of surgical repositioning, proper time for root development, Proper socket formation, and minimal trauma are important for success. This case presents displaced impacted maxillary central incisor with dilacerated root. The development of root is Nolla's stage 7, and the tooth was treated by surgical repositioning. We can observe no root resorption and good healing pattern.

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

Purpose: This study aims to measure the improvement of balanced ability and rapid response of 30 healthy adults by performing dynamic stretching, static stretching, and sargent jump. Methods: The sample 30 peoples without any musculoskeletal disease who volunteered to be the subject of the study. We measured all subjects on following metrics to evaluate the function and stability under the normal condition, with dynamic stretching (DS) group, static stretching (SS) group: vertical jump height and reaching distance Anterior, Posteromedial, Posterolateral and NO (Normal eye open), NC (Normal eye close), PO (Pillow with eye open), and PC (Pillow with close eye) were evaluated. All measures were analyzed using independent t-test and One-way repeated Anova. Results: There was a significant increase in SJH (Sargent jump) in both groups (p<0.05). In Y-balance test, there was a significant increase in both groups except for the ANT (Anterior) direction, and there was a significant increase only in the SS group in the ANT (Anterior) direction (p< 0.05). There was no significant difference between the DS group and the SS group (p >0.05). There was no significant improvement in ST (Stability Index) and WDI (Weight Distribution Index) in both groups (p>0.05). Conclusion: Both DS and SS showed significant improvement in SJH and Y-balance tests, which are dynamic functions, but had no significant effect on static balance ability.

Electrochemical capacitors based on hierarchical porous activated carbon nanofiber (RuO2/ACNF) composites are fabricated by one-step electrospinning, and then stabilized at different activation temperatures. The effect of the activation temperature on the structural properties and electrochemical behavior of the RuO2 /ACNF composites is intensively investigated in 6 M KOH electrolyte. The RuO2 /ACNF-800 composites activated at high temperature possess abundant mesopores and larger pores, which improve the electrochemical performance, especially at high charge–discharge rates. The energy storage capabilities of the RuO2 /ACNF-800 electrode prepared at high temperature are as follows: a maximum specific capacitance of 150 F/g and an energy density of 14–20 Wh/kg in the respective power density range of 400 to 10 000 W/kg in an aqueous solution. Furthermore, this electrode exhibits high-rate electrochemical performance with a specific capacitance reduction of less than 28% of the initial value at a discharge current of 20 mA/cm2. Therefore, the hierarchical porous RuO2 /ACNF composites with well-developed mesoporous structure provide low resistance for charge diffusion and a short pathway for ion transportation, yielding good capacitive behavior.
