Objective : The fracture on the frontal bone in head-injured patients may be commonly encountered in the clinical situations. Biomechanical studies demonstrate that the anterior wall of the frontal sinus is intermediate in its ability to resist fracture on direct impact. If the frontal sinus is large and the anterior table is able to disperse the force of the impact over a greater area, the posterior table and intracranial contents usually can be spared. We analyzed the clinical features of the patients who presented with frontal skull fracture due to frontal blows. Patients and Methods : From January, 1992 to December, 1997, 172 patients with frontal skull fracture were selected among 1911 patients with head injury who were admitted to department of neurosurgery. Clinical records and radiological studies of all patients were reviewed and evaluated retrospectively. Results : The neurobehavioral changes was seen in 34 cases(19.8%) and showed statistical significances in case of facial bone fractures, acute subdural hematoma(SDH), and positive frontal lobe releasing sign(p<0.05). The good glasgow outcome score group(GOS, good recovery & moderate disability) at discharge was revealed in 77.3% of total patient population. The poor GOS group(severe disability & vegetative state & death) at discharge was revealed in 22.7%. The poor GOS group at discharge have statistical significances with acute epidural hematoma(EDH), traumatic intraventricular hemorrhage(t-IVH), traumatic intracranial lesion, poor initial glasgow coma scale(GCS) scores & Revised Trauma Score(RTS)(p<0.05). Conclusion : Because of their anatomical relationships and neurobehavioral patterns due to vulnerability of the frontal lobe, the frontal injury should be considered as complicated facial injuries. Therefore, these patients are more likely to have a cosmetic or neuropsychiatric problems.

Obstructive sialadenitis, one of the diseases that most frequently causes swelling and pain in the salivary glands, is mainly caused by structural obstructions. Sialolithiasis is the most frequent cause of the disease, and other causes include calculus formation, duct strictures, foreign bodies, and anatomical variations. Although there is a possibility that facial fillers directly block the salivary ducts, no cases of obstructive sialadenitis associated with them have been reported yet. We report the case of a 34-year-old female patient who complained of recurrent swelling and pain in the left buccal mucosa. She had undergone facial filler injection procedures on her facial area for cosmetic purposes several years before. Based on the findings of magnetic resonance imaging (MRI) and MR sialography, she was diagnosed with obstructive sialadenitis due to facial fillers. Through this case, we should remember to obtain a thorough history including filler treatments in the case of parotid gland swelling. We also suggest proper utilization of advanced imaging such as MRI in evaluating the location of facial fillers.

Background and Objectives High-intensity focused ultrasound (HIFU) can produce small zones of thermal damage. A HIFU procedure is non-invasive and it can achieve rejuvenation of facial skin. Fractional CO₂ laser resurfacing delivers thermal damage to the pixilated columnar zone of the skin and so evoke collagen remodeling, the same as HIFU. In many cases, the patients who want rejuvenation with HIFU are also good candidates for cutaneous photorejuvenation such as can be accomplished via fractional CO₂ resurfacing. If patients are treated in a single session by remodeling both the superficial and deep compartments of skin by using both modalities, then improvement in rhytides and tightening of sagging skin will optimize the aesthetic result. Materials and Methods Between May 2014 and January 2018, a total of 44 patients were treated with combination HIFU and fractional CO₂ laser resurfacing according to our protocol. First, the HIFU was applied to the entire face with an average of 300 treatment lines. Immediately after HIFU treatment, the ultrasound gel was washed off and then fractional CO₂ laser resurfacing was performed. We evaluated the patients using 4-point grading scales. The clinician examined the skin for evidence of complications after the completion of treatment. Results All the patients' skin quality showed improvement. Further. the clinical results after duel modality treatment were substantially better than that after the use of either modality alone. The recovery times and the incidence of adverse events when quickly and consecutively performing both treatments were similar as compared to those with employing stepwise treatment. We encountered no complications whatsoever. Conclusion When compared with stepwise therapy, combination therapy with HIFU and fractional CO₂ resurfacing offers better, safer and more effective clinical results. Thus, for targeting multiple layers of aging facial skin, this combination therapy can be safely performed in a single treatment session.

The initial instance of isolated unilateral temporalis muscle hypertrophy (IUTMH) was reported in 1990. Since then, only few cases have been documented. The cause of this condition remains ambiguous; however, it is presumed to be linked to compensatory and stress-induced hypertrophy. We introduce a rare case of the diagnosis and treatment of IUTMH. A 39-year-old woman presented with a steadily enlarging pain-free swelling on the left side of her face, first noticed a month ago. Apart from a hyperthyroidism medication regimen her medical history was unremarkable. She had no history of temporomandibular joint disease, bruxism, surgery, or trauma. However, she complained of having been under substantial stress lately. Contrast-enhanced magnetic resonance imaging revealed asymmetric temporalis muscle hypertrophy. The treatment plan consisted of administering type A botulinum toxin injections into left temporalis muscle, supplemented by lifestyle changes and relaxation techniques. At a follow-up visit 9 months after the injections, the muscle contour was normalized both in physical and in radiologic examinations. While further supportive evidence is needed, it can be anticipated that cosmetic treatment with botulinum toxin, rather than surgical interventions, will become the standard treatment of IUTMH.

Purpose: Pedicled transverse rectus abdominis myocutaneous(TRAM) flap has been a gold standard for breast reconstruction and one of surgical techniques preferred by many surgeons. The authors examined the course of deep epigastric artery focusing on distance from margins of rectus abdominis to pedicle and location of choke vessels to get minimal muscles during pedicled TRAM flap operation. Methods: Eleven rectus abdominis muscle from nine cadavers were used in this study. Rectus abdominis was separated from the cadavers, deep inferior and superior epigastric artery were isolated and then 8 anatomical landmarks in medial and lateral margins of rectus abdominis were designated. Distance to a pedicle meeting first horizontally was measured and vertical location from umbilicus to choke vessel was determined. In addition, 32 rectus abdominis images of 16 women(average age: 37.2 years old) from 64 channel abdomen dynamic computerized tomography were also examined with the same anatomical landmarks with those of cadavers. Results: Average distance from four landmarks on lateral margin of rectus abdominis to pedicle was 1.9 - 3.4cm and 1.8 - 3.8 cm on medial margin. Choke vessel was located between middle and inferior tendinous intersection in all cases and average distance between two tendinous intersection was 6.7 - 7.0 cm on medial margin and 6.2 cm on lateral margin. Location of inferior tendinous intersection was on umbilicus or superior of it in all cases and its average distance from umbilicus was 1.8 - 5.6 cm on medial margin and 2.7 - 6.2 cm on lateral margin. Conclusion: Distance from medial and lateral margins of rectus abdominis muscle to pedicle was the shortest in inferior tendinous intersection and that was averagely 1.8 cm on medial margin and 1.9 cm in average on lateral margin. All choke vessels were located between middle and inferior tendinous intersection.

프로세스 마이닝에서는 일반적으로 SAP ERP와 같은 정보시스템이 남기는 시스템의 디폴트 로그를 분석해왔지만, RPA라는 자동화 소프트웨어의 사용이 확대됨에 따라 RPA 봇이 남기는 로그를 활용할 수 있게 되었다. 본 연구에서는 RPA 봇을 국내 제조기업(코스메틱 분야) 3개 사의 업무에 적용하여 로그를 남긴 후 분석함으로써 현업의 RPA 자동화에 대한 실제 현황을 파악하였다. Uipath와 파이썬을 이용하여 RPA 봇을 구현하고 로그를 남겼으며, 봇이 남긴 로그의 분석을 위해서는 프로세스 마이닝 전용 소프트웨어인 Disco를 사용하였다. 프로세스 마이닝을 통해 봇의 활용성과 성능이라는 두 측면에서 로그 분석을 해 본 결과, 개선 요구사항을 찾아볼 수 있었다. 특히 봇의 활용성 측면에서 활용도를 높여야 하는 경우가 많았고, 수행과정에서 오류나 예외발생 및 수행시간이 길어지는 구간이 발견된다는 점에서 모든 사례에서 개선 지점이 존재하고 있는 것으로 분석되었다. 이러한 분석은 설문이나 인터뷰에 의존했던 기존의 정성적 방법이 아닌 데이터를 활용한 증거 기반의 분석으로 봇의 자동화 현황과 성과를 분석한다는 점에서 매우 과학적이며 또 현업의 업무에 적용된 사례라는 점에서 실증적 의미를 갖는다. 나아가 '로그 마이닝 기반 자동화 현황 분석'은 봇 행동 최적화를 위한 의미있는 기초 단계로, 궁극적으로 프로세스 경영을 수행할 수 있는 토대가 된다고 볼 수 있다.
