Impaction and ectopic eruption of Permanent teeth can cause various clinical Problems. These teeth are not hopeless. It is possible to use the remaining teeth as anchorage, surgically uncover the impacted tooth, and orthodontically move the tooth into the arch. The specific surgical procedure and the orthodontic mechanics, however, will vary depending upon the type of tooth and its position relative to the remaining erupted teeth. There are different surgical techniques for the surgical exposure of the impacted teeth. These case reports described the surgical exposure using the apically positioned flap(APF) and closed eruption technique ,

Spectroscopic ellipsometry 은 다양한 물질의 광학적 특징을 연구할 수 있는 강력한 기술이다. 현재 실리콘 웨이퍼 위의 박막 분석에는 그 효율성이 확실히 입증되어 있다. 그러나 현재 산업은 유리 기판위의 박막을 분석하기를 원하고 있다. Ellipsometry로 투명기판을 분석하기 위해서는 후면 반사에의한 비간섭성 효과를 고려해야 한다. 기존의 반사공식을 투명기판의 비간섭성을 고려하여 수정하였다. 투명기판 위의 샘플과 scratch를 낸 같은 샘플을 측정 분석하여 정확성을 확인하였다. 수정된 반사공식을 이용하면 디스플레이와 같은 투명재료를 이용하는 곳에 유용하게 사용될 것으로 기대되고 있다. A Spectroscpic ellipsometry is very strong technology to study optical properties of many materials. It has already substantiated a analytic efficiency about thin films above wafers to be made of silicon. However, the current industry needs thin films analyzed on a glass. When we analyze a glass using a ellipsometry, we have to consider a efficiency of incoherence due to reflect at the back side. So then, we slightly altered the original formula. We compared a scratched sample with a sample on the glass, because off getting a exactitude. Our technical development, using the changed formula, is expected the useful utilization in a part of using gIasses such as display.

금박막은 높은 전도성의 화학적인 안정성을 가지고 있으므로 GaAs를 기판으로 한 bevice에서 널리 쓰이고 있으며 SAM(Self-Assembled Monolayer), Nanolithography 등에서도 아주 주요하게 사용되고 있다. 본 연구에서는 염소가 포함된 액체에 금박막이 접해있고 UV를 조사하여 식각이 되는 것을 발견하고 연구하였다. 노광량을 조절하여 금박막의 기각률을 조절할수 있으며, 또한 가모강제 공정을 거치지 않고 금박막에 직접 조사하게 되므로 간단하게 패터닝을 할수 있다. AFM(atomic force microscope), optical microscope, ellipsometry 를 이용하여 식각률 측정 및 표면 변화를 보았다. Various metals or their alloys are used in the semiconductor metallization process or in micro-or nano-structure devices. We report a novel etching technique of gold film based on new phenomenon that gold is soluble in chlorine containing solutions or solvents under UV irradiation. Mask patterns can be transferred to gold surface directly without resorting to complicate photoresist process. And, etch rate could be controlled from sub nanometer to few tens of nanometers per minute by adjusting exposure parameters. Moreover, non-toxic liquid such as NaCl solution can be used for the process. AFM(atomic force microscope), optical microscope, ellipsometry were used to characterize the etch rate and the surface morphology.

( Deok Gyeong Kim ),( Hui Gyeong Suh ),( Ji Won Min ),( Sun Kyeong Kim ),( Yun Sook Kim ),( Jong Eun Lee ) 대한산부인과학회 2018 대한산부인과학회 학술대회 Vol.104 No.-

Small bowel perforation in the postpartum period is very rare and is often misdiagnosed as functional paralytic ileus after surgery or pain at the wound, rapid and accurate diagnosis can be very difficult and delayed for various reasons, which can threaten the life of the mother. In the past 10 years, we have had experienced two cases of duodenal ulcer perforation after cesarean section. In all two cases, there was no past history of the ulcer, the first case was too severe and laparotomy after laparoscopic attempt was performed, and the second case was treated laparoscopic surgery by 3-0 V-LocTM absorbable wound closure device. In case of unexpected abdominal pain, especially in the case of accompanying fever during well recovery 4-7 days after cesarean section, if the surgical site is normal, the gastrointestinal disorder should be considered.

Purpose: The goal of oncoplastic breast surgery is to restore the appearance of the breast and improve patient satisfaction. Thus, the assessment of cosmetic results and patient-reported outcomes (PROs) using appropriately constructed and validated instruments is essential. The aim of the present study was to assess the long-term objective cosmetic results and corresponding PROs after oncoplastic breast surgery. Methods: Cosmetic results were assessed by the patients, a medical panel, and a computer program (BCCT.core). PROs were assessed using BREAST-Q, a questionnaire that measures the perception of patients having breast surgery. The cosmetic results and PROs were analyzed in patients who underwent quadrantectomy and partial breast reconstruction utilizing the latissimus dorsi flap. Results: The mean duration of the follow-up period was 91.6 months (range, 33.3–171.0 months), and mean age of the patients was 51 years old (range, 33–72 years). The mean tumor size was 2.1 cm (range, 0.9–5.5 cm). There was fair agreement between the medical panel and BCCT.core score (K = 0.32, P < 0.001), and a statistically significant correlation between the BCCT.core score and medical panel cosmetic results was identified (r = 0.606, P < 0.001). A better BCCT.core result was related to a higher PRO of each BREAST-Q domain—satisfaction with breasts (R<SUP>2</SUP> = 0.070, P = 0.039), satisfaction with outcome (R2 = 0.087, P = 0.021), psychosocial well-being (R<SUP>2</SUP> = 0.085, P = 0.023), sexual well-being (R<SUP>2</SUP> = 0.082, P = 0.029), and satisfaction with information (R<SUP>2</SUP> = 0.064, P = 0.049). Conclusion: Our long-term results of oncoplastic surgery achieved a high level of patient satisfaction with good cosmetic results. The medical panel and BCCT.core results correlated well with the PROs of the patients using valid, reliable, and procedure-specific measures.

( Deok Gyeong Kim ),( Hui Gyeong Suh ),( Ji Won Min ),( Sun Kyeong Kim ),( Yun Sook Kim ) 대한산부인과학회 2018 대한산부인과학회 학술대회 Vol.104 No.-

Objective: The Objective of this study was to assess the positive culture rate and antimicrobial susceptibilities of Mycoplasma hominis (MH) and Ureaplasma urealyticum (UU) in general population and pregnant women. Methods: We reviewed a retrospective medical records of patients who have undergone culture test and antimicrobial susceptibilities at our center from April 2018 through January 2017. The study included all patients with positive culture for MH, UU or both. Results: The condition was assessed in 200 patients. All of them, 34 (17%) were pregnant women and 166 (83%) were non-pregnant women. From 105 (52.5%) out of total 200 had a positive culture as follows: MH 46 (23%), UU 95 (47.5%) and both 36 (18%). Susceptibilities of MH to doxycycline, erythromycin, ciprofloxacin, and azithromycin were 97.8%, 6.5%, 17.4%, and 8.7%, respectively. Susceptibilities of UU to doxycycline, erythromycin, ciprofloxacin, and azithromycin were 95.8%, 55.8%, 7.4%, and 56.8%, respectively. Susceptibilities of both MH and UU to doxycycline, erythromycin, ciprofloxacin, and azithromycin were 97.2%, 5.6%, 11.1%, and 11.1%, respectively. Conclusion: UU was the leading causative pathogen for genitourinary infection in our study. MH accounted for about half of the UU infection rate. Doxycycline was still best susceptible to UU, MU, and both. Ciprofloxacin had less than 20% susceptibility to MU, UU, both. The major problem is that the pregnant women is infected with MU and both are not sensitive to erythromycin and azithromycin at all.

Kim, Hee Nam,Kim, Nan Young,Yu, Li,Kim, Yeo-Kyeoung,Lee, Il-Kwon,Yang, Deok-Hwan,Lee, Je-Jung,Shin, Min-Ho,Park, Kyeong-Soo,Choi, Jin-Su,Kim, Hyeoung-Joon Molecular Diversity Preservation International (MD 2014 INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES Vol.15 No.4

<P>The damage caused by oxidative stress and exposure to cigarette smoke and alcohol necessitate DNA damage repair and transport by multidrug resistance-1 (MDR1). To explore the association between polymorphisms in these genes and non-Hodgkin lymphoma risk, we analyzed 15 polymorphisms of 12 genes in a population-based study in Korea (694 cases and 1700 controls). Four genotypes of DNA repair pathway genes (<I>XRCC1</I> 399 GA, <I>OGG1</I> 326 GG, <I>BRCA1</I> 871 TT, and <I>WRN</I> 787 TT) were associated with a decreased risk for NHL [odds ratio (<I>OR</I>)<SUB>XRCC1 GA</SUB> = 0.80, <I>p</I> = 0.02; <I>OR</I><SUB>OGG1 GG</SUB> = 0.70, <I>p</I> = 0.008; <I>OR</I><SUB>BRCA1 TT</SUB> = 0.71, <I>p</I> = 0.048; <I>OR</I><SUB>WRN TT</SUB> = 0.68, <I>p</I> = 0.01]. Conversely, the <I>MGMT</I> 115 CT genotype was associated with an increased risk for NHL (<I>OR</I> = 1.25, <I>p</I> = 0.04). In the <I>MDR1</I> gene, the 1236 CC genotype was associated with a decreased risk for NHL (<I>OR</I> = 0.74, <I>p</I> = 0.04), and the 3435 CT and TT genotypes were associated with an increased risk (<I>OR</I><SUB>3435CT</SUB> = 1.50, <I>p</I> < 0.0001; <I>OR</I><SUB>3435TT</SUB> = 1.43, <I>p</I> = 0.02). These results suggest that polymorphisms in the DNA repair genes <I>XRCC1</I>, <I>OGG1</I>, <I>BRCA1</I>, <I>WRN1</I>, and <I>MGMT</I> and in the <I>MDR1</I> gene may affect the risk for NHL in Korean patients.</P>
