  • Background: In recent years, there has been an increase in reports of perioral vascular complications resulting from filler injections, such as necrosis of the lip or alar rim, occlusion, and in severe cases, blindness. Conversely, the use of perioral arterial flaps is becoming more prevalent in the treatment of cleft lips, cancer, and trauma. A thorough understanding of perioral arteries is essential to minimize complications and maximize the success of these flaps. However, the course of the facial artery (FA) in the perioral region remains incompletely understood. The aim of this study was to describe the variations of the FA in the perioral region. Methods: We dissected 52 embalmed and formaldehyde-fixed Vietnamese cadavers. We then studied the size and distribution of perioral arteries in 102 specimens. Results: The superior labial artery (SLA) was the most common branch, occurring in 87.25% of cadavers, followed by the inferior labial artery (ILA) at 78.43%. The SLA primarily originated above the mouth corner (cheilion), accounting for 91.01% of cases, and predominantly exhibited a tortuous course within the submucosa (78.65%). The ILA's branching pattern varied, but it was primarily located below the cheilion (91.25%). The ILA also followed a twisted path, generally within the submucosa. The ILA exhibited two patterns: the typical pattern, distributed at the vermilion border of the lower lip (8.82%), and the horizontal labiomental artery pattern, which ran horizontally in the middle of the lower lip area (69.61%). At their origin, the SLA and ILA had average external diameters of 1.29 mm and 1.28 mm, respectively. Conclusion: Numerous anatomical variations in the FA in the perioral region were found. A detailed anatomic description, suggested landmarks, and angiography before the procedure will be useful to help doctors avoid complications.

  • Paragonimiasis is an important food-borne parasitic zoonosis caused by infection with lung flukes of the genus Paragonimus. Of the 7 members of the genus known in Thailand until recently, only P. heterotremus has been confirmed as causing human disease. An 8th species, P. pseudoheterotremus, has recently been proposed from Thailand, and has been found in humans. Molecular data place this species as a sister species to P. heterotremus, and it is likely that P. pseudoheterotremus is not specifically distinct from P. heterotremus. In this study, we collected metacercariae of both nominal species (identification based on metacercarial morphology) from freshwater crabs from Phetchabun Province in northern Thailand, Saraburi Province in central Thailand, and Surat Thani Province in southern Thailand. In addition, we purchased freshwater crabs imported from Myanmar at Myawaddy Province, western Thailand, close to the Myanmar-Thailand border. The DNAs extracted from excysted metacercariae were PCR-amplified and sequenced for ITS2 and cox1 genes. The ITS2 sequences were nearly identical among all samples (99-100%). Phylogenies inferred from all available partial cox1 sequences contained several clusters. Sequences from Indian P. heterotremus formed a sister group to sequences from P. pseudoheterotremus-type metacercariae. Sequences of P. heterotremus from Thailand, Vietnam, and China formed a separate distinct clade. One metacercaria from Phitsanulok Province was distinct from all others. There is clearly considerable genetic variation in the P. heterotremus complex in Thailand and the form referred to as P. pseudoheterotremus is widely distributed in Thailand and the Thai-Myanmar border region.

  • A long-term follow-up study of a case of impacted teeth associated with a large dentigerous cyst in the left maxilla is presented. The patient was a 30-year-old man who had a large dentigerous cyst in the premaxilla and left posterior maxilla, which impacted the canine and supernumerary tooth. This is one of the most prevalent types of odontogenic cysts associated with an erupted or developing tooth, particularly the mandibular third molars. The other teeth commonly affected in order of frequency are the maxillary canines, maxillary third molars and rarely, the central incisor. Radiographically, the cyst appears as huge ovoid well-demarcated unilocular radiolucency with a sclerotic border and causes ectopic displacement of the inferior border of the maxillary sinus without destruction. Dentigerous cysts may grow unnoticed to such extensive sizes as to occupy a considerable portion of the maxillary sinus. These cysts appear to be associated with a supernumerary tooth in the maxillary anterior incisors region called the mesiodens and impacted canine. The present case report describes the surgical enucleation of a dentigerous cyst involving the permanent maxillary left canine and mesioden. After surgery, left maxillary sinus recovered their normal size and apposition of bone was observed around the apex of the posterior teeth. During the subsequent years, there was no recurrence of the cystic lesion but the inflammation was evoked in the anterior maxilla after 42 months. This complication appeared to have correlated with bony healing in the enucleation site of the cyst. We report the healing status of a huge dentigerous cyst in the maxilla for 5 years with a review of the relevant literature.

  • Three Jang-Ue's and eleven drapery were investigated in the excavated costume in Ue-Ryeong, Gyeong-Sang-Nam-Do. Three Jang-Ue's have three different colors. the length, the width, and the wide of quilting are different as well. The outer collar of a coat is a double collar while the inturned collar is a single collar. In case of Dark blue and Pink Jang-Ue. The large section of cloth forming the body of a Korean coat is getting narrower while the reinforcing cloth strip is getting wider as the time is passing by. All the three Jang-Ue's have the different handling methods of a attached to the top border of a Korean coat, and Pink Jang-Ue doesn't have a attached to the tip border of a Korean coat. The handling method of the hemline are all different. And the handling method of the cuffs are all different. The silk is main in the woven goods, partly hemp, mixed fabrics and cotton. Especially complex gauze with supplementary wefts that were found unusually in Cho-Sun Dynasty are very import to study the complex gauze. The fond relics of the Jeon-Ui Lee family reveal various formational methods and specific characters of the excavated costume. There fore these that bring the Jang-Ue shape and the textile's feature in Gyeong-Sang-Nam-Do region, from 16th to 17th are very valuable.

  • 미국-멕시코 국경지대는 멕시코의 마킬라도라 산업에 대한 세계 다국적기업들의 투자로 인해 고용확대, 인구증가, 산업발달이 이루어지고, 특히 국경지대의 쌍둥이 도시들은 많은 사회경제적 변화를 겪게 되었다. 1965년에 시작된 멕시코의 마킬라도라 프로그램은 외국기업의 투자를 유치하기 위한 보세가공 산업정책이었는데, 2006년부터는 멕시코인 소유의 수출기업을 포함하는 IMMEX 프로그램으로 대체되었다. 마킬라도라를 포함한 IMMEX 기업들은 2007년 이후 업체수는 큰 변화가 없는 반면 업체당 종사자수는 점차 대형화하고 있다. 업종별로 보면 자동차, 항공기와 관련된 운송장비제조업이 가장 크게 성장하였으며, 과거 마킬라도라 산업에서 큰 비중을 차지하던 섬유·직물·의류제조업은 상대적으로 침체의 길을 걷고 있다. IMMEX의 비제조업 분야에서는 종사자수와 해외매출액에 있어서 농업의 비중이 압도적이다. IMMEX 기업들의 지역적 분포에서는 티화나와 후아레스가 압도적으로 높은 비중을 차지하고 있다.

  • 우리나라는 정전으로 남북관계가 대치됨에 따라 남북의 MDL(군사분계선)을 기준으로 남북 간의 전쟁이 언제라도 촉발될 수 있는 위험한 상황에 처해 있다. 또한, 타 국가의 국경과는 달리 남북의 접경지역은 전쟁으로 촉발될 수 있는 생명의 위협을 느낄 수 있는 곳이 최전방 접적지역이다. 접적지역과 같은 특수한 지역에서 근무하는 병사들은 지역적 여건상 접근성이 용이하지 못하여 외출, 외박, 면회가 적은 실정이고, 근무 환경은 야밤에 넓은 숲과 적막함이 넘치고 적과 근접하여 언제 어떤 상황이 일어날지 모르기에 불안함과 외로움 그리고 불안함이 과중 되는 지역이다. 따라서 이곳에서 목숨을 내놓고 국방의 의무를 수행하는 병사들에게 관심을 갖고 병영생활을 안전하고 충실히 마칠 수 있도록 많은 도움이 필요할 것이며, 접적지역 복무병사들의 심리적 적응을 위한 지원이 필요하다.

  • This study conducted a big data analysis study through text mining and semantic network analysis to explore the perception of defense reform 2.0. The collected data were analyzed with the top 70 keywords as the appropriate range for network visualization. Through word frequency analysis, connection centrality analysis, and an N-gram analysis, we identified issues that received much attention such as troop reduction, shortening of military service period, dismantling of the border area unit, and returning wartime operational control. In particular, the results of clustering words through CONCOR analysis showed that there was a great interest in pursuing the technical group, concerns about military capacity reduction, and reorganization of manpower structure. The results of the analysis through text mining techniques are as follows. First, it was found that there was a lack of awareness about measures to reinforce the reduced troops while receiving much attention to the reduction of troops in Defense Reform 2.0. Second, it was found that it is necessary to actively communicate with the local community due to the deconstruction and movement of the border area units, such as the decrease of the population of the region and the collapse of the local commercial area. Third, it was judged that it is necessary to show substantial results through the promotion of barracks culture and the defense industry, which showed that there was less interest than military structure and defense operation from the people and the introduction of active policies. Through this study, we analyzed the public's interest in defense reform 2.0, which is a representative defense policy, and suggested a plan to draw support for national policy.
