본 연구는 풍도, 부속실, 거실 그리고 계단실로 구성된 구조물의 제연설비 성능에 관한 연구를 수행하고 급기 가압실의 안전성을 구현하기 위한 실험 자료를 구축하고자 하는데 목적이 있다. 이를 위해서 부속실 가압 및 차압 조절 설비와 방화문의 개폐력 측정 장치를 제작하였다. 본 주제는 부속실의 가압을 위한 설계유량과 폐쇄시 차압이 동일한 경우 방화문의 크기와 닫히는 각속도 증가에 따라서 폐쇄력을 분석하였다. 실험 결과 방화문의 크기와 닫히는 각속도가 증가 할수록 폐쇄력이 증가하였으며, 일정 각속도 이상으로 증가할 경우 폐쇄력이 일정하게 유지되는 임계각속도가 존재하는 것을 확인하였다.

비강 및 부비동에 발생하는 유두종은 비교적 드문 양성종양으로서 수술적 제거후에도 재발이 잘되고 악성화되는 경향이 있는 정도로 알려져 있다. 유두종의 3 Type중 특히 희귀한 균상 유두종은 Microscopically stratified squamous epithelium으로 덮힌 Cornification의 형태를 보이며 출현의 경향은 별로 없는 것으로 알려져 있다. 저자들은 최근 55세 남자의 우측 비강측벽에 발생한 균상유두종 한례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Objective: To summarize the high-resolution computed tomography (HRCT) and magnetic resonance imaging (HRMRI) features of duplicated internal auditory canals (DIACs). Materials and Methods: Ear HRCT data of 64813 patients with sensorineural hearing loss (SNHL), obtained between August 2009 and November 2017, were reviewed. Among these patients, 12 (13 ears) were found to have DIACs, 9 of whom underwent HRMRI. Their images were evaluated by two otoradiologists. Results: The rate of occurrence of DIAC among SNHL patients was 0.019% (12/64813). The internal auditory canals of 13 ears were divided into double canals by complete (n = 6) and incomplete (n = 7) bony septa, with varied orientations ranging from horizontal to approximately vertical. All of the anterosuperior canals extended into the facial nerve (FN) canal, except for 1, which also extended to the vestibule. The posteroinferior canals ended in the cochlea and vestibule, except for 2, which also connected to the FN canals. Magnetic resonance images revealed that 77.8% (7/9) and 22.2% (2/9) of vestibulocochlear nerves (VCNs) were aplastic and hypoplastic, respectively. Furthermore, 88.9% (8/9) of FNs were normal, except for 1, which was hypoplastic. All of the affected ears also had other ear anomalies: a narrow, bony cochlear nerve canal was the most common other anomaly, accounting for 92.3% (12/13). Malformations of other systems were not found. Conclusion: Double-canal appearance is a characteristic finding of DIAC on HRCT, and it is usually accompanied by other ear anomalies. The VCN usually appears aplastic, with a normal FN, on HRMRI.

연구목적: 본 연구는 가변형 트레이 개발의 일환으로 그 시제품을 제작하고 비가역성 수성 콜로이드 인상재를 사용하여 중국인과 일본인에서 인상채득 시 트레이의 구강 내 적합성를 알아보고자 하였다. 연구재료 및 방법: 가변형 트레이는 한국 성인 악궁의 크기 분석결과를 기본으로 하여 설계하였으며, 먼저 CAD-CAM 작업을 통하여 견본 모형을 제작한 후, 이를 똑같이 복제한 실리콘 간이금형을 만들었다. 그리고 이 금형에 polyurethane을 주입하여 다수의 시제품을 완성하였다. 시제품을 이용하여 중국인으로는 상해 제2의과대학교 구강의학원 학생 60명 (남자 30명, 여자 30명)을 대상으로 하였고, 일본인으로는 일본 구마모토 고등학교 졸업생 60명 (남자 30명, 여자 30명)을 대상으로 인상채득을 실시하고, 측정부위별로 인상체의 두께와 길이를 측정한 후 통계처리를 하여 그 적합성을 평가하였다. 결과: 1. 중국인과 일본인 모두 스탑과 경사면에 의해 트레이의 폭이 적절히 조절되어 대체적으로 3-6mm의 균일한 인상체의 두께를 얻을 수 있었다. 2. 중국인의 상악 트레이에서는 전치 순측 변연부에서 두께가 6.2mm, 견치 순측 변연부에서 두께가 5.9mm, 구개부 중앙은 10.5 mm, 구개부 후방은 9.7mm 높이로 비교적 인상체의 두께가 크게 측정되었다. 3. 중국인의 하악 트레이에서는 제1, 2소구치 접촉점 설측 변연부에서 인상체의 길이가 8.9mm, 전치 설측 변연부에서 7.2mm로 길게 나타났으며, 견치 순측 6.8mm, 소구치 순측 7.0mm로 인상체의 두께가 크게 측정되었다. 4. 일본인의 상악 트레이에서는 전치 순측 변연부에서 두께가 7.4mm, 견치 순측 변연부에서 7.7mm, 구개부 중앙은 9.1mm 높이로 인상체의 두께가 비교적 크게 측정되었다. 5. 일본인의 하악 트레이에서는 견치 순측 7.4mm, 제1, 2소구치 접촉점 순측 변연부 8.4mm로 인상체의 두께가 크게 측정되었다. 결론: 본 가변형 치과 인상용 트레이는 한국인 모형 계측치를 바탕으로 설계되어 한국인에서 적합성이 우수하며, 본 실험의 결과 중국인과 일본인에서도 적합성이 좋아 본 트레이를 범용하여 쉽고 정확한 인상채득을 할 수 있을 것이다.

A 2-year-old male pseudohermaphrodite in Korean native cattle was observed macroscopically and microscopically. The results were summarized as follows. In the female reproductive organs, the vulva and vestibule were normal size, but the vagina and uterus were shorter and smaller abnormally. The uterine tube and ovary were absent, but the small testes was located in the abdominal cavity.

The author evaluated the effectiveness of pedicled buccal fat pad grafts for closure of oroantral communications. Nine patients with chronic oroantral communications and one patient with an oronasal communication were treated with pedicled buccal fat grafts. They were treated successfully in all cases, and there were no postoperative complications (i. e. shallow buccal vestibule), and minimal patient discomforts. It was concluded that this was a easy and time fast method for closure of oral defects and had wide application and high successful rate.

Verrucous carcinoma is a distinctive form of low-grade squamous cell carcinoma. The tumor has an exophytic, cauliflower-like appearance, and usually occurs in males and tends to affect individuals over 60 years of age. It typically involves the oral cavity, larynx, esophagus and skin. Most intraoral cases involve the mandibular vestibule, the buccal mucosa and the hard palate. The cause is unknown, but most verrucous carcinomas arise from the oral mucosa in people who chronically use chewing tobacco or snuff. The treatment of oral verrucous carcinoma remains controversial. Whenever possible, surgically total excision and skin or mucosal grafting is recommended. After total excision of huge verrucous carcinoma,instead of dermal or mucosal grafting, we used artificial dermis silicone membrane. We had a good result without recurrence and present this case.

In the course of modernization coupled with industrialization and urbanization. Maru or wooden floor and Teachong or great hall of Han-ok or traditional Korean housing has experienced functional as well as physical changes to a remarkable degree. The author made an analysis of the transfiguration of Maru/Taechong space(M/T) with relation to: 1)Madang or yard. 2)Anbang or inner room, 3)Hyon-kwan or vestibule. 1) In relation to Madang, interiorization of M/T by way of setting sliding glass doors has begun to appear. 2) In connection with Anbang, division of role/function is being observed as far as family entertainment and reception of intimate friends is concerned. 3) Owing to wider acceptance of Hyon-kwan space as a buffer zone system, the advent of Keo-sil or living room is thought to be facilitated. The analysis, however, does not say that Keo-sil of modernized Korean housing might well be interpreted as the mere extension type of M/T of the vernacular housing.

Loud click or tone burst sound can activate vestibular receptor and evoke reflex changes in tonic electromyographic activity within the stenocleidomastoid muscles. This reflex is assumed to originate in the saccule, the afferent pathways being the inferior vestibular nerve, and the efferent pathways the vestibulospinal tract. Averaging these muscular responses allows vestibular evoked myogenic potentials (VEMP) to be obtained. The earliest response ipsilateral to a loud click, p13n23, is dependent upon vestibular activation, specifically saccular afferents. These new techniques are beginning to be applied clinically in the patient of vestibular neuritis, Meniere's disease, acoustic neuromas, Tullio phenomenon, etc. VEMP recording will provide both a straightforward non-invasive exploration of each vestibule independently and an attractive method by which to explore otolithic receptors and vestibulospinal pathways.

Congenital syngnathia refers to the fusion of bony tissues, a rare disorder with only 41 cases reported in the international literature from 1936 to 2009. The occurrence of syngnathia without any other associated systemic disease or congenital anomaly is extremely rare. This report presents a case of congenital syngnathia with unilateral maxillomandibular bony adhesion without any other oral or maxillofacial anomaly. No recommended protocol for surgery exists due to the rarity of the disorder. There is a very low survival rate for the few patients who have forgone surgical management. This case describes a 74-year-old female patient who was suffering from limitation of mouth opening and was subsequently diagnosed with congenital syngnathia. The surgical staff performed separation surgery and reconstructed the malformed oral vestibule and cheek using the radial forearm free flap operation.
