The study surveyed preference and Actual Condition of wedding fashion masterpiece brand by consumer's lifestyle group. First, it was found that the brand preference by wedding fashion masterpiece consumer was Bulgari in precious metal, Burberry in scarf, Louisvuitton in bag and Chanel in cosmetics. Second, as a study result of purchase status, wedding fashion masterpiece brand consumers, who enjoy shopping about 1 time a month, usually purchased the masterpiece in masterpiece hall of department store. Their total purchase amount for wedding was less than 5 million in most cases. Third, regarding purchase-experience brand by consumer's lifestyle group, in clothes, there was significant difference between 4 groups such as shopping unconcerned type, reasonable economic type, self-focused brand-oriented type and social achievement type. In bag, slight difference appeared in 4 groups. Fourth, as a study result of the brand preference by consumer's lifestyle group, there was somewhat significant difference between precious metal, clothes, scarf, bag and cosmetic variables. Fifth, as a study result of the difference of information source use by consumer's lifestyle group, it was found that social achievement type used most various sources such as commerce, store and personnel information. Sixth, as a study result of shopping trend by consumer's lifestyle group, social achievement group searched for pleasure, unique personality and ostentation. Shopping unconcerned type searched for necessary shopping with comfortable style without sparing time in shopping.

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.

With the increase in the number of cases of silicone implant insertion either for cosmetic surgery or breast reconstruction after mastectomy, it is not unusual to encounter patients with silicone implants in clinical settings. Recently, the first case of breast implant-associated anaplastic large cell lymphoma was reported in Korea. In addition to previously known complications, such as implant rupture or contracture, the number of implant-associated imaging examinations has also increased. Considering this background, radiologists should have sufficient knowledge about the type of examination required in patients who have undergone implant insertion and imaging findings to correctly identify implant-associated complications. In this article, various complications of silicone implants are discussed, including various imaging findings, which radiologists should know.

Purpose: Soft tissue defects of the distal lower extremity are commonly accompanied by a fracture of the lower extremities. Theses defects are caused by the injury itself or by complications associated with surgical treatment of the fracture, which poses challenging problem. The reverse superficial sural artery flap (RSSAF) is a popular option for these difficult wounds. This paper reviews these cases and reports the clinical results. Materials and Methods: Between August 2003 and April 2018, patients who were treated with RSSAF for soft tissue defects of the lower third of the leg and ankle related to a fracture were reviewed. A total of 16 patients were involved and the mean follow-up period was 18 months. Eight cases (50.0%) of the defects were due to an open fracture, whereas the other eight cases (50.0%) were postoperative complication after closed fracture. The largest flap measured 10×15 cm² and the mean size of the donor sites was 51.9 cm². The flap survival and postoperative complications were evaluated. Results: All flaps survived without complete necrosis or failure. One case with partial necrosis of the flap was encountered, but the wound healed after debridement and repair. One case had a hematoma with a pseudoaneurysmal rupture of the distal tibial artery. On the other hand, the flap was intact and the wound healed after arterial ligation and flap advancement. A debulking operation was performed on three cases for cosmetic reasons and implant removal through the flap was performed in three cases. No flap necrosis was encountered after these additional operations. Conclusion: RSSAF is a relatively simple and safe procedure for reconstructing soft tissue defects following a fracture of the lower extremity that does not require microsurgical anastomosis. This can be a useful treatment option for soft tissue defects on the distal leg, ankle, and foot.

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.

Process mining has generally analyzed the default logs of Information Systems such as SAP ERP, but as the use of automation software called RPA expands, the logs by RPA bots can be utilized. In this study, the actual status of RPA automation in the field was identified by applying RPA bots to the work of three domestic manufacturing companies (cosmetic field) and analyzing them after leaving logs. Using Uipath and Python, we implemented RPA bots and wrote logs. We used Disco, a software dedicated to process mining to analyze the bot logs. As a result of log analysis in two aspects of bot utilization and performance through process mining, improvement requirements were found. In particular, we found that there was a point of improvement in all cases in that the utilization of the bot and errors or exceptions were found in many cases of process. Our approach is very scientific and empirical in that it analyzes the automation status and performance of bots using data rather than existing qualitative methods such as surveys or interviews. Furthermore, our study will be a meaningful basic step for bot behavior optimization, and can be seen as the foundation for ultimately performing process management.

The obstructive diseases involving the left main coronary artery(LMCA) are serious. Surgical treatment is generally regarded as much more effective than medical therapy in terms of long-term survival and relief of symptoms. This study represents an attempt to present an analysis of early surgical results in 21 cases conducted at Chonnam University Hospital between October 1992 And August 1995. The subject. 12 males and 9 female, ranged in age from 25 to 67 years with a mean age of 49.3${\pm}$12.5 years. As for indications for operation, unstable angina was reported on 66.7% of the subjects, while stable angina and acute myocardial infarction in 4 and 3 cases, respectively. There were also 2 cases of Takayasu's aortitis and 1 case of failed percutaneous translumlnal coronary angioplasty(PTCA). Eleven subjects had isolated LMCA diseases compared to 10 subjects with associated LMCA diseases. Of the patients with ass;3ciated LMCA diseases, 4 subjects had single coronary artery disease, 3 had double coronary artery disease, remaining 3 suffered from triple coronary artery disease. As for the group with isolated LMCA disease, ostidl angioplasty llsing autopericardium was conducted with 5 subjects. The remaining subjects with the isolated diseases and all of the patients with associated LMCA disease underwent aortocoronary bypass grafts. The left internal mammary artery was used in all patients and the average number of anastomoses was 3.13 ${\pm}$0.93. One subject died of low cardiac output syndrome at the second postoperative day. There were 5 instances of postoperative complication including reoperation for bleeding in two patients, wound infection in two, and arrhythmia in one. Follow-up coronary angiogram were conducted with eights patients, including five patients who underwent ostial angioplasty. In these cases, the patients showed surf. ficient enlargement of the left coronary ostium and the grafted vessels kept their patency. In our experience, surgical treatment of the LMCA diseases has not shown a higher rAte of operative mortAlity or morbidity than other obstructive coronary artery diseases. To patients with ostial stenosis, which is frequently observed among young female, angioplasly utilizing autopericardium seems to be a desirable choice considering the cosmetic effect, chances of reoperation and hemodynamic characteristics.
