Objectives: The anterior open bite with temporomandibular disorders (TMD) is one of the most challenging cases both orthodontically and surgically. We introduce an intermaxillary traction treatment for patients with anterior open bite and TMD using a skeletal anchorage system (SAS). Materials and Methods: This study was comprised of 52 patients with anterior open bite and TMD. A total of four mini-screws were inserted, two screws each into the maxilla and mandible, to obtain a class II pattern of elastic application with 120-200 g force. Adjunctive muscle relaxation treatments, such as splint therapy, medication, and botulinum toxin injection were applied during or before intermaxillary traction. At least one treatment among adjunctive muscle relaxation treatment, mentioned above, was applied to 96.2% of patients. We evaluated the clinical characteristics of patients, TMD symptom changes, amount of open bite improved. The degree of open bite improvement was compared between the open bite-reduced group (21 patients) and not-reduced group (5 patients). Results: TMD symptoms (muscle/joint pain, joint sound, mouth opening) remained or improved in most patients, and worsened in about 10% of patients for each items. Anterior open bite was improved by a mean of 1.75 mm (P<0.01) during treatment. The open bite-reduced group exhibited a significant open bite improvement compared to the not-reduced group (P<0.05), with 37% of open bite improvement occurring during the first 3 months of treatment. Conclusion: The intermaxillary traction technique using SAS is a valid modality for correction of anterior open bite and improvement of TMD symptoms.

Objective: The aim of this study was to compare posterior tooth inclinations, occlusal force, and contact area of adults with different sagittal malocclusions. Methods: Transverse skeletal parameters and posterior tooth inclinations were evaluated using cone beam computed tomography images, and occlusal force as well as contact area were assessed using pressure-sensitive films in 124 normodivergent adults. A linear mixed model was used to cluster posterior teeth into maxillary premolar, maxillary molar, mandibular premolar, and mandibular molar groups. Differences among Class I, II, and III groups were compared using an analysis of variance test and least significant difference post-hoc test. Correlations of posterior dental inclinations to occlusal function were analyzed using Pearson's correlation analysis. Results: In male subjects, maxillary premolars and molars had the smallest inclinations in the Class II group while maxillary molars had the greatest inclinations in the Class III group. In female subjects, maxillary molars had the smallest inclinations in the Class II group, while maxillary premolars and molars had the greatest inclinations in the Class III group. Occlusal force and contact area were not significantly different among Class I, II, and III groups. Conclusions: Premolar and molar inclinations showed compensatory inclinations to overcome anteroposterior skeletal discrepancy in the Class II and III groups; however, their occlusal force and contact area were similar to those of Class I group. In subjects with normodivergent facial patterns, although posterior tooth inclinations may vary, difference in occlusal function may be clinically insignificant in adults with Class I, II, and III malocclusions.

본 연구의 목적은 국내 광고산업의 집적 특성과 광고제작의 공간적 네트워크를 고찰하는 것이다. 광고산업은 다른 비즈니스 서비스와 마찬가지로 서울의 집중도가 높기 때문에 서울 내에서의 집적 특성을 중점적으로 분석하였다. 업종별 종사자수의 지역별 비중과 더불어 로컬 모란 I와 입지계수 방법이 분석에 이용되었다. 광고산업의 강남지역 집중이 두드러지게 나타나는데, 이것은 신생 기업들의 강남지역 지향 입지와 국내 진입 외국계 광고대행사의 강남지역 선호와 관련이 있다. 또한 네트워크 분석 방법을 이용해 TV광고 제작의 공간적 네트워크를 분석했다. 광고대행사-광고제작사 네트워크 매트릭스를 구축하고, 이를 지역 매트릭스로 변환한 후, 중심성 분석과 중개 분석을 통해 광고제작의 공간적 네트워크를 고찰하였다. 이를 통해 강남 세부지역의 상이한 역할과 지위를 알 수 있는데, 강남지역 내부와 외부의 광고대행사들이 강남지역에 있는 광고제작사에 대부분의 광고제작을 아웃소싱하고 있다. 이러한 분석을 통해 광고산업이 강남지역이 광고제작의 목적지로서 뿐 아니라 강남지역에서 광고제작 네트워크가 순환되고 있음을 알 수 있다.

Background Currently, breast conservation therapy is commonly performed for the treatment of early breast cancer. Depending on the volume excised, patients may require volume replacement, even in cases of partial mastectomy. The use of the latissimus dorsi muscle is the standard method, but this procedure leaves an unfavorable scar on the donor site. We used an endoscope for latissimus dorsi harvesting to minimize the incision, thus reducing postoperative scars. Methods Ten patients who underwent partial mastectomy and immediate partial breast reconstruction with endoscopic latissimus dorsi muscle flap harvest were reviewed retrospectively. The total operation time, hospital stay, and complications were reviewed. Postoperative scarring, overall shape of the reconstructed breast, and donor site deformity were assessed using a 10-point scale. Results In the mean follow-up of 11 weeks, no tumor recurrence was reported. The mean operation time was 294.5 (${\pm}38.2$) minutes. The postoperative hospital stay was 11.4 days. Donor site seroma was reported in four cases and managed by office aspiration and compressive dressing. Postoperative scarring, donor site deformity, and the overall shape of the neobreast were acceptable, scoring above 7. Conclusions Replacement of 20% to 40% of breast volume in the upper and the lower outer quadrants with a latissimus dorsi muscle flap by using endoscopic harvesting is a good alternative reconstruction technique after partial mastectomy. Short incision benefits from a very acceptable postoperative scar, less pain, and early upper extremity movement.

Objectives : The purpose of this study is to explore the trends of acupoints used for lumbar HIVD(Herniated Intervertebral Disc) and treatment and anatomical location of Hwatahyeopcheock. Methods : We searched the latest clinical studies on acupuncture treatment for lumbar HIVD(Herniated Intervertebral Disc) through domestic studies search. To analyze the data, we categorized them by year and article types of literatures and investigated often-used acupoints and acupuncture types for treatment by reading treatment part of every paper searched. Domestic and Chinese literatures related to Hwatahyeopcheock were also studied for its anatomical location. Results : Total 50 articles are searched and local points are more used than distant points for lumbar HIVD(Herniated Intervertebral Disc) and most of them showed curative effects. Back-su points were used the most and Hwatahyeopcheock use accounted for one-third of the articles. In the articles of Hwatahyeopcheock use, except for one, patients complained of both low back pain and radiating pain, and all of them showed positive results after treatment. Conclusions : Back su point is considered to have its meaning as physical region where patients feel pain including herniated disc level rather than the effect meridian system makes. Through document research and meridian muscle theory, we found that Hwatahyeopcheock means vertebral facet joint, intervertebral foramen and surrounding muscle, nerve, blood vessel and related spinal nerves.

Objectives : The purpose of this study is to explore the trends of Chuna(manipulation) treatment on neck pain and cervical disc displacement. Methods : We set up the two searching strategies and investigated the latest clinical trials on Chuna(manipulation) therapy for Neck disorders and cervical disc herniation through PubMed search. The searched papers were analyzed and the year, journals, article types of literatures were examined. Of the articles, Randomized controlled trials(RCTs) are assessed by Jadad scale. Results : Studies on Chuna(manipulation) treatment to cervical disc herniation were very few. Articles on Chuna(manipulation) treatment to neck pain were relatively more than those of cervical disc herniation. The most frequently published journal was J Manipulative Physiol Ther. The main design of study was RCT. The limited quality assessment of RCT was conducted by Jadad scale and the average Jadad score was 1.73, which indicates low quality in terms of Jadad evaluation criteria. Conclusions : International trends of studies on Chuna therapy of cervical disease is increasingly reviewed. Although this review has several limitations, analyzing the latest trends of studies on Chuna(manipulation) treatment on neck pain and cervical disc displacement is necessary for further studies.

Purpose: To determine the impact of pseudoglandular formation on apparent diffusion coefficient (ADC) values of hepatocellular carcinoma (HCC) in diffusion-weighted imaging (DWI), and to validate the results using histopathological grades. Materials and Methods: We assessed 182 HCCs surgically resected from 169 consecutive patients. Each type of tumor pseudoglandular formation was categorized into "non-," "mixed-," or "pure-," based on official histopathology reports. The ADC for each tumor was independently measured, using the largest region of interest on the ADC map. Data were assessed using the analysis of variance test, with Bonferroni correction for post hoc analysis to stratify the relationship of ADCs with pseudoglandular formation, followed by subgroup analysis according to the histopathological tumor grades. Results: The mean ADC was significantly higher in pure pseudoglandular lesions (n = 5, $1.29{\pm}0.08{\times}10^{-3}mm^2/s$) than in non-pseudoglandular lesions (n = 132, $1.08{\pm}0.17{\times}10^{-3}mm^2/s$; P = 0.003) or mixed-pseudoglandular lesions (n = 45, $1.16{\pm}0.24{\times}10^{-3}mm^2/s$; P = 0.034). The ADC values and pseudoglandular formation were significantly correlated in moderately differentiated HCCs (n = 103; r = 0.307, P = 0.007), while well- (n = 19) and poorly-differentiated HCCs (n = 60) did not show significant correlation (r = 0.105 and 0.068, respectively; P = 0.600 and 0.685, respectively). Conclusion: The degree of pseudoglandular formation could be one of the determinants of ADC in DWI of HCCs-especially moderately differentiated HCCs-while its influence does not appear to be significant in well- or poorly differentiated HCCs.

본 연구는 2003년 11월부터 2013년 8월까지의 전국, 수도권, 비수도권, 강남, 강북지역 아파트 매매가격의 합리적 버블을 전체기간과 글로벌금융위기 전 후로 기간을 나누어 상태공간모형과 칼만필터를 이용해 추정하였다. 전체기간 중에 강남은 합리적 버블이 25.4%로 가장 높고 강북 21.3%, 수도권 20.1%, 전국 18.9%, 비수도권 14.3%로 나타났다. 글로벌 금융위기 이전에는 강남이 26.7% 강북 19.3%로 강남이 강북보다 약 7.4% 정도 버블이 높게 형성되어 있다. 이에 반해 글로벌 금융위기 이후에는 강남 13.2%, 강북 10.7%로 버블이 많이 붕괴되었으나 오히려 비수도권 지역은 이전기간 4.2%에서 이후기간 19.0%로 약 15% 상승을 하였다. 이는 강남, 강북을 포함한 수도권은 매매가격이 하락하고 임대료는 상승을 하였고 비수도권 지역은 공공기관 이전 등 각종 개발호재로 인해 매매가격이 상승한 것이 주요원인으로 생각된다.
