Objective : This is to report the effectiveness of intraoral distraction osteogenesis for alveolar augmentation in the extremely atrophied alveolar defects and to review the clinical results of the 2 cases. Subjects and Methods : Anterior segmental osteotomy was performed and the trans-oral alveolar distractors(Martin, Germany) were applied in 2 patients with the severe acquired anterior maxillary and mandibular defect. After latent period for 1 week, the osteomized alveolar segments were distracted by 1 ㎜ a day (0.5 ㎜/l turn) for 8 days in case Ⅰ and 0.6 ㎜ a day(0.3 ㎜/l turn) for 10 days in case Ⅱ. The consolidation period was about 8 weeks in each case. Thereafter, 6 titanium threaded implants(Branemark, Restore) were simultaneously installed with removal of distractor. The implants were tested clinically and radiographically. Results : Amounts of acquired alveolar bone were 8 ㎜ in case Ⅰ and 6 ㎜ in case Ⅱ respectively, with the increased width of the ridge crests and soft tissue expansion. Dental implants installated on the augmented alveolar ridges in 8 weeks after distrction were confirmed as in good osseointegration and in good function without any complications. Conclusion : Intraoral distraction osteogenesis can be a good option for alveolar ridge augmentation of the severely atrophied ridges and soft-tissue defects. However, for the better vector control of distracting segments and for anterior esthetics, customized distraction devices could be considered later.

Objectives: This study was performed to evaluate whether there is the difference of graft height changes in radiographic evaluation in single implants and multiple implants after maxillary sinus floor augmentation with an auto-xenograft mixture. Methods: The study group comprised 29 patients (16 men, 13 women; mean age, 56.5±12.4 years; range, 27 to 87 years) treated at the implant clinic of the Ewha Womans University Mokdong Hospital. They were treated with the sinus floor augmentation of lateral window technique and simultaneous placement of dental implants. Their implants have been evaluated for 42.4±10.5 months. To evaluate the height of grafted material, the real implant length was compared with that of panoramic radiography evaluated by a digital caliper (PACS program), and then the real height of grafted material was assumed. SPSS 19.0 was used in statistical analysis. Wilcoxon singed rank test was utilized for P value and Mann-Whitney for statistical significance in the changes of grafted height between single implants and multiple implants. The level of statistical significance was defined as P<0.001. Results: The evaluated graft height in single implants' group decreased to 0.60±0.54 mm at the time of delivery (after 7.5 months, P=0.001), in multi-unit implants' group to 0.96±0.84 mm (after 6.5 months, P<0.001). The evaluated graft height in single implants' group decreased to 1.11±0.75 mm at the last follow-up (after 43.5 months, P=0.001), in multi-unit implants' group to 1.52±0.99 mm (after 41.8 months, P<0.001). Mann-Whitney test was used for the difference between single implants and multi-unit implants. There was no difference in two groups at the time of delivery and the last follow-up (P>0.001). Conclusion: There was no statistical significance of radiographic graft height after maxillary sinus floor augmentation between single implants and multiple implants.

Sixty four patients were followed-up for over 6 months following the orthognathic surgeries and were examined for the Temporo-mandibular joint dysfunction. The results are as follows: 1. Of 64 patients, 9(14.1%) had been suffered from TMD preoperatively : 47% in the prognathism and 46.2% in the laterognathism. 2. Following the orthognathic surgeries, 7 of 64 patients(10.9%) complained TMD, and 55.6% of the TMD patients resulted in significant improvement. 3. By the type of deformities, laterognathism with TMD could be expected to be improved in 30.8%, while 7.7% in the prognathism. 4. Non-rigid fixation resulted in higher incidence of TMD than the Rigid fixation after the SSRO ; 4 of 15(26.5%) and 2 of 25(8.0%) respectively.

Elongation of the styloid process (styloid syndrome, Eagle's Syndrome) is named after Eagle who insisted the styloid process as a cause of pain but distinguishable from the glossopharyngeal neuralgia. Eagle's syndrome is characterized by a dull nagging pharyngeal pain, a palpable hardness in the tonsillar fossa, radiopaque elongation and enlargement of the syloid process. This is to report two cases of Eagle's Syndrome. The clinical and radiological features, development and pathogenesis of the Eagle's Syndrome and pathologic findings of the calcified styloid ligaments were described with review of literatures. The external cervical approach to resect the enlarged calcified processes can be an option due to better visualization and accessbility, less infection at risk than intra-oral approach. The findings and results were as follows : 1. The calcified styloid ligaments accompanied with throat pain were reseded in size of 5.5×48mm(#1,Rt), 3.6×5mm(#1, Lt), 5.2×51mm(#2, Rt) and 3.1×38mm(#2, Lt). 2. The submandibular approach to resect the calcified styoid process is of help to get better visibility and accessiblilty avoiding the injury to the deep cervial vital structures. 3. The resected styloid processes were examined histopathologically as the matured cortical bones with marrow structures or cartilagenous cells without any findings of neoplasmic changes. 4. The remained process did not show any noticeable regrowth in 3 years after surgical amputation.

This study was designed to evaluate the ability of the injured trigeminal nerve to regenerate in the bone, and to compare the axonal regeneration following the nerve graft and nerve tubulization with GTR membrane. Fourteen rabbits were divided into 3 groups as follows : not repaired(Gc), Entubulation(G_1), and nerve graft(G_2) after partial resection of inferior alveolar nerves in the mandibular canals. The neuro-fibrotic tissues regenerated in the nerve gaps were prepared for histomorphologic examination by special staining with Hematoxylin & Eosin, Luxol-fast blue, Bodian's Masson-trichrome. The regenerated axons were examined with Toluidine blue staining and Transmission electronmicroscopy(TEM). The injured mandibular nerve presented a regenerative capacity across 7 cm defect, and tubular repairs with GTAM produced histomorphologic regeneration of neural axons and mini-fascicles in 16 weeks. This investigation, however, showed a finding that autogenous nerve graft was inferior to tubulization in the histomorphologic assessment. The group of nerve graft disclosed less organized neural tissue(mini-fascicles) with more fibrovascular collagenous tissues. Nerve injury resulting a gap which cannot be repaired by primary neurorrhaphy needs grafts or intrpositional tubular nerve guides. The e-PTFE membrane or tube can be used as a good conduit or sheath for nerve regeneration without adhesion of connective tissues, while the grafted nerves in the mandibular and bony ingrowth. Electrophydiologic examination and qualification of the regenerated axons are recommended to evaluate the substantial recovery following the nerve repair modalities.

Speaker recognition is the technology that confirms the identification of speaker by using the characteristic of speech. Such technique is classified into speaker identification and speaker verification; The first method discriminates the speaker from the preregistered group and recognize the word, the second verifies the speaker who claims the identification. This method that extracts the information of speaker from the speech and confirms the individual identification becomes one of the most efficient technology as the service via telephone network is popularized. Some problems, however, must be solved for the real application as follows; The first thing is concerning that the safe method is necessary to reject the imposter because the recognition is not performed for the only preregistered customer. The second thing is about the fact that the characteristic of speech is changed as time goes by, So this fact causes the severe degradation of recognition rate and the inconvenience of users as the number of times to utter the text increases. The last thing is relating to the fact that the common characteristic among speakers causes the wrong recognition result. The silence parts being included the center of speech cause that identification rate is decreased. In this paper, to make improvement, We proposed identification rate can be improved by removing silence part before processing identification algorithm. The methods detecting speech area are zero crossing rate, energy of signal detect end point and starting point of the speech and process DTW algorithm by using two methods in this paper. As a result, the proposed method is obtained about 3% of improved recognition rate compare with the conventional methods.

In 2018 2nd semester, 134 students who were attending the ‘A Day of Busan’ were asked to take this survey. Among them, 78 students were from Busan. This paper analyzed these 78 students. According to the respondents' grades, 52.6% of the respondents were in the first grade, slightly more than half, and the second was 33.3%. It can be seen that the 'A Day of Busan' course are mainly in interested in lower grades. According to the year of birth of the respondents, the birth rate in 1999 was 43.6% of the total, including one missing value. In this questionnaire, we surveyed and analyzed the religion of the students, the parent's home, the typical food of Busan, representative places in Busan, and the personality, strengths and weaknesses of Busan people. We also surveyed students' lives, for example, the number of participating in Pusan International Film Festival, the number of visits to professional baseball games, the number of overseas trips, using mobile phones time per day, the number of close friends, sleeping hours. Also we surveyed the population size of Busan. The proportion of students who replied that population size is less than the actual population of 3.45 million in Busan was similar to that of students who replied that it is more. 2018년도 2학기 ‘부산의 하루’ 수강생 가운데 부산출신 학생 78명을 대상으로 분석을 하였다. 응답자의 학년별 구성을 보면 1학년이 52.6%로 절반을 조금 넘고, 그 다음은 2학년으로 33.3%이었다. ‘부산의 하루’ 과목은 주로 저학년이 수강하는 것을 알 수 있다. 응답자의 출생연도를 보면 1999년 출생자가 결측값 1명을 포함한 전체에서 43.6%를 점하여 가장 높은 비율을 보였다. 응답학생 78명의 종교를 보면 무교가 61.5%로 압도적인 비중을 점하고 있다. 그 다음으로 불교가 20.5%, 개신교가 12.8%, 가톨릭이 3.8% 그리고 기타종교가 1.3%였다. 아버지의 고향은 부산이 53.8%로 절반을 넘으며, 그 다음은 경남으로 24.4%였다. 부산과 경남을 합하면 78.2%로 절대적인 비중을 점하고 있다. 어머니의 고향은 부산이 56.4%, 경남이 11.5%로 부산과 경남을 합하면 67.9%였다. 부산의 대표음식으로는 돼지국밥이 36.2%, 21.2%의 어묵, 15.7%의 밀면, 8.7%의 씨앗호떡, 7.4%의 생선회 순이었다. 타지역에서 오는 친구들에게 보여주고 싶은 곳으로는 광안리가 17.9%, 해운대로 13.1%, 서면으로 10.3였다. 그 다음으로는 롯데야구 6.1%, 광안리불꽃놀이 5.3%, 센텀시티 5.1%, 광안대교 4.9% 순으로 나타나 주로 광안리와 해운대 그리고 서면 쪽으로 쏠리는 경향이 나타났다. 부산에서 새로 생기면 좋은 것에 대한 설문에서는 놀이공원이 13.3%, 워터파크10.8%, 공원 8.7%, 체육관 8.2%, 수목원과 박물관이 각각 5.8%로 나타나 학생들은 놀이시설을 가장 원하고 있었으며 그 다음으로 공원과 체육관을 선호하였다. 부산사람들의 성격에서 좋은 점이 무엇인가에 대해서는 ‘의리있다’가 17.8%로 가장 많았고, 나쁜 성격은 32.5%의 압도적인 비율이 성격이 ‘급하다’로 나타났다. 즐겨마시는 음료에는 커피가 33.3%로 가장 높았고, 그 다음은 26.9%의 콜라였다. 주중 술 마시는 횟수에 대한 설문에는 ‘전혀 마시지 않는다’는 학생이 38.5%로 약 40%에 해당하는 학생이 전혀 술을 마시지 않는 것으로 나타났다. 부산국제영화제에 참여한 횟수, 부산에서 열린 프로야구 경기에 참여한 경험, 해외 여행 횟수에 대한 설문에 대해서는 각각 전체의 64.1%, 35.9%, 33.3%의 학생들이 한번도 없는 것으로 나타났다. 하루 휴대전화 사용시간의 평균은 271분, 친한 친구수의 평균은 13명, 수면시간은 평균은 6.8시간, 한달 용돈은 평균 35만원이었다. 부산의 인구가 얼마나 되겠는가 하는 설문에 대한 응답은 매우 다양하였는데, 2만명에서부터 3,800만명까지 넓은 범위에 걸쳐 분포하였다. 그런데 부산의 실제인구 345만명 선보다 적다고 응답한 학생의 비율이 약 절반이었고 나머지 절반은 그보다 많다고 응답하였다.
