The objective of this study is to evaluate the stress distribution according to the thread design and the marginal bone loss of a single unit dental implant under the axial and offset-axial loading by three dimensional finite element analysis. The implants used had the diameter of 5mm and 4mm with 13mm in length and prosthesis with a conical type which is 6mm in height and 12mm in diameter. The thread designs were triangular, square and buttress. In the three dimensional finite element model with $15\times15\times20mm$ hexahedron and 2mm cortical thickness, implants were placed with crown to root ratio 7:12, 10:9, 13:6 and 16:3. And additionally the axial force of 100N were applied into 0mm, 2mm and 4mm away from the center of the implants. The results were as follows 1. The maximum von-Mises stress in cortical bone was concentrated to cervical area of implant, and in cancellous bone, apical portion. 2. Comparing the von-Mises stresses in cortical bone of 2mm and 4mm offset loading with central axial loading, it were increased to 3 and 5 times in diameter 4mm implant, and 2 and 4 times, in diameter 5mm implant. 3. The square threads were more effective than the triangular and butress as the longer diameter, the offset loading, and the worse crown to root ratio. 4. The von-Mises stresses were relatively stable until crown to root ratio 13:6, but it was suddenly increased at 16:3. From the results of this study, minimum requirement of crown to root ratio of implant is 2:1, and in the respect of crown to root ratio, diameter and offset loading, square threads are more effective than triangular and buttress threads.

김일규,이성호,오성섭,최진호,오남식,김왕식,임영일,양동환,Kim, Il-Kyu,Lee, Seong-Ho,Oh, Seong-Sub,Choi, Jin-Ho,Oh, Nam-Sik,Kim, Wang-Sik,Rim, Young-Il,Yang, Dong-Whan 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.3

림프관종의 치료에 있어 전통적으로 수술적요법만이 선호되어져 왔으나 최근 Ogita 등에 의해 소개된 OK-432는 안전성과 효과면에서 기존의 경화제에 비해 뚜렷이 구별되는 효과를 지니고 있는 것으로 여러 저자등에 의해 보고되고 있다. 특히 수술이 매우 어려운 부위에 존재하는 경우라든지 수술후 재발된 증례등에서 일차 혹은 이차적으로 투여하여 높은 성공률을 보였다고 하였고 더불어 OK-432 투여후 시행된 수술시에도 섬유성유착등의 어려움없이 병소를 절제할 수 있다고 하였다. 본 증례의 경우도 일차적인 OK-432 투여후 8개월째 시행된 이차적인 수술에서 큰 어려움없이 병소를 절제할 수 있었다. 이에 저자등은 좌측 혀 및 구강저와 경부의 급성 부종으로 인한 호흡부전 및 대설증의 증상을 보여 본원 소아과에서 의뢰된 생후 5개월된 환자에게 병력 및 임상검사와 방사선적 검사를 시행한 결과 림프관종으로 진단하고 일차적으로 흡입천자를 통한 감압술과 OK-432 를 통한 경화요법을 시행하였고 이차적인 연속수술을 시행하여 병소를 완전히 절제하였으며 술후 현재까지 재발소견없이 양호한 결과를 보였기에 이에 보고하고자 한다. Lymphangiomas are relatively rare benign tumors of the lymphatic system, characterized by congenital lymphatic malformation such as anastomosis or obstuction of the lymphatic channels. There are most frequently diagnosed in children younger than 3years. In contrast to that of the hemangioma, the sex distribution of the lymphangioma is nearly evenly divided. The head and neck lymphangioma represents about $70{\sim}75%$ of all lymphangiomas, and they are difficult to manage. Spontaneous regression is rare, and rapid intermittent enlargement occurs secondary to infection or trauma. Enlargement may cause serious sequelae such as airway obstruction, feeding difficulties, and cosmetic problems. Treatments previously used for lymphangiomas include surgical excision and intralesional injection of sclerosants. Problems associated with surgical excision include the risk of cosmetically unacceptable scarring and the risk of damage to surrounding vital stricture and the high risk of incomplete excision. The sclerosants previously used have numerous other local and systemic side effects. This report describes a case that was successfully treated using OK-432 as a new sclerosant drug and secondary surgical excision for congential cavenous lymphangioma extensively enlarged to tongue, mouth floor and submandibular region.

An experimental study on island effects related to“double relative clauses” in Korean

김일규 경희대학교 언어정보연구소 2017 언어연구 Vol.34 No.3

In this paper, I test the validity of two competing approaches to island effects: syntactic and functional. Based on two acceptability judgment tasks on Korean relative clauses that are closely related to double relative clauses, I argue that the functional approach is superior to the syntactic approach at least in explaining Korean data. To be more specific, the results of the experiments show that Korean relativization is mainly affected by a semantico-pragmatic constraint called the Characterization Constraint, rather than by syntactic islands, the Complex NP Constraint in particular.

Utilization of Patent Information for Humanitarian Purpose: Focusing on Technologies in the Public Domain

김일규 서울대학교 아시아태평양법연구소 2013 Journal of Korean Law Vol.12 No.2

Due to its exclusive nature of intellectual property rights, there have been numerous tensions between intellectual property and human rights. In order to reconcile those tensions, many different kinds of efforts, especially in the area of patent, have been made, which include legislative, licensing, and policy-based approaches. However, one of the best ways to acquire accessibility to technologies without legal constraint is to use technologies in the public domain. Many life-improving technologies that people in least developed countries (LDCs) need might be found in patent documents under public domain, because not only many patents are expired way before their legally allowed protection term of twenty years, but also technologies which impoverished people need usually may not be the technologies which were recently patent granted. In addition, many of patented technologies in developed countries are not usually filed at LDCs. Recent projects conducted by the Korean Intellectual Property Office and World Intellectual Property Organization show how to utilize patent information in assisting impoverished people in LDCs, which might be another reconciliatory way of tensions between developed and developing countries regarding patent system.

The mucocele is a mucus extravasation cyst arising from the salivary gland. Although it is a common?lesion of the minor salivary gland, it is uncommon when it originated from the submandibular gland. The ranula is a form of mucocele which specifically occurs in the floor of the mouth and the sublingual gland is generally accepted as the origin of ranula. They can be classified into two types based on extent: simple ranula are confined to the sublingual space and plunging ranula extend into the adjacent space. It is difficult to differentiate the submandibular gland mucocele from the plunging ranula because both of them can occupy the submandibular space. A 37-year old male visited our clinic with the chief complaint of left facial swelling. The patient's history revealed that he had suffered from a cystic lesion on the left side of the floor of the mouth 10 months previously. He supposed the cystic lesion had come from trauma at other dental clinics. Using CT and MRI, we diagnosed a simple ranula on the sublingual space and a submandibular gland mucocele. We then excised the mucocele with the submandibular gland by an extraoral approach and the sublingual gland by an intraoral approach under general anesthesia. We report a rare case of an enormous submandibular gland mucocele which extended into the pterygoid plate and parapharyngeal space with good surgical results.

Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Immunosuppressive type. Epidemic categories is found approximately 20% of all AIDS patients and has strong predilection for head and neck region. The first case of immunosuppresive type Kaposi's sarcoma in patients with kidney transplants was reported in 1969. Kaposi's sarcoma accounts for 5% of all tumors associated with transplanted patients. The most common site of Kaposi's sarcoma in immunosuppressed patients are extremities, but rare in head and neck area. A 42 years old woman who had systemic lupus erythematosus visited to our clinic because of gingival hyperplasia, and excisional biopsy revealed Kaposi's sarcoma. We experienced a case of favorable results using excision and chemotherapy, so we report with review of literatures. 본 증례는 전신성 홍반성 낭창으로 인해 2000년 4월부터 면역 억제제인 azathioprine 75mg과 prednisolne 35mg을 복용 중인 42세 여성 환자가 2004년 12월 상악 협측 치은의 종창, 증식, 동통 및 출혈을 주소로 내원하여 조직 생검 결과 모세 혈관종으로 진단되었으나, 2005년 1월 치은의 재발 병소의 절제 및 조직 생검으로 카포시 육종으로 진단되었고, 흉부의 피부 병변의 조직 생검과 흉부 전산화 단층 촬영 검사에서도 양측 폐에 다수의 결절을 보이는 카포시 육종으로 진단되었다. 의인성 면역억제제에 의한 카포시 육종으로 최종 진단되어, 면역 억제제와 부신피질호르몬제의 중단과, paclitaxel을 이용한 전신적인 항암화학 요법으로, 2008년11월 현재까지 재발의 징후 없이 구강, 피부, 폐의 병소에 대해 양호한 치료 결과를 얻었으나, 향후 전신성 홍반성 낭창의 악화 또는 카포시 육종의 재발 가능성이 있으므로 지속적인 추적 관찰이 요할 것으로 사료된다.

상하악에 동시 다발성 골신장술을 이용한 반안면왜소증의 치험례

김일규,박종원,이언화,양정은,장재원,편영훈,주상현,왕 붕,Kim, Il-Kyu,Park, Jong-Won,Lee, Eon-Hwa,Yang, Jung-Eun,Chang, Jae-Won,Pyun, Yeong-Hun,Ju, Sang-Hyun,Wang, Boon 대한악안면성형재건외과학회 2010 Maxillofacial Plastic Reconstructive Surgery Vol.32 No.5

The hemifacial microsomia is characterized by variable underdevelopment of the craniofacial skeleton, external ear, and facial soft tissues. So, patients with hemifacial microsomia have an occlusal plane canting and malocclusion with facial asymmetry. Distraction osteogenesis (DO) with an intraoral or extraoral device is a technique using tension to generate new bone with gradual bone movement and remodeling. DO has especially been used to correct craniofacial deformities such as a hemifacial microsomia, facial asymmetry, and mandible defect that could not adequately be treated by conventional reconstruction with osteotomies. It has a significant advantage to lengthen soft and hard tissue of underdeveloped site without bone graft and a few complication such as nerve injury or muscle contracture. A 13-years old girl visited our clinic for the chief complaint of facial asymmetry. She had a left hypoplastic maxilla and mandible, occlusal plane canting and malocclusion. We diagnosed hemifacial microsomia and lanned DO to lengthen the affected side. Le Fort I osteotomy, left mandibular ramus and symphysis osteotomy were performed. The internal distraction devices fixed with screw on maxillary and mandibular ramus osteotomy sites. External devices were adapted to lower jaw for DO on symphysis osteotomy site and to upper jaw for rapid maxillary expansion (RME). At 7days after surgery, distraction was started at the rate of 1mm per day for 13days, and after 4months consolidation periods, distraction devices were removed. Simultaneous multiple maxillo-mandibular distraction osteogenesis with RME resulted in a satisfactory success in correcting facial asymmetry as well as occlusal plane canting for our hemifacial microsomia.

구강내 발생한 심상성 천포창 환자의 치험례

Pemphigus vulgaris is a chronic autoimmune intraepithelial blistering disease with oral mucosal manifestations that very often precede the skin lesions. The vesicles or bullae are produced by an acantholytic process, detachment of differentiating keratinocytes from one another in the epithelial stratum spino sum or spinous cell layer. The pathogenesis of this disease is initially manifested by IgG(mainly) binding to desmosome(desmoglein 3 or 1) in the intercellular spaces of epithelium. This autoantibody binding caused the release of a plasminogen activator(a proteolytic enzyme) from keratinocytes. This ultimately results in cell to cell separation. The mainstay therapy of pemphigus vulgaris is systemic corticosteroids and immunosuppressive agents to eliminate the pathogenic autoantibodies from circulation. A 41-year old woman presented with a 1.5 year history of oral ulceration. There were no lesions on the skin or other mucosal sites. Histology and immunostaining were consistent with pemphigus vulgaris. Control of oral ulceration and normal oral function were achieved after systemic corticosteroids and immunosuppressive agents were instituted.
