Purpose:The purpose of this study is to identify static, dynamic balance performances and foot pressure after eye movement exercise in normal adults. Method:This study was performed on normal 18 males and 18 females subjects. They were divided into 3 groups using random sampling and executed saccadic eye movement, vestibuloocular eye movement, pursuit vergence eye movement exercise respectively. In order to compare the difference of balance and foot pressure, the subjects were measured before, middle and after eye movement. Balance was examined using the balance master 7.0 version systems. Foot pressure was examined using the gaitview AFA-50. Result:The result are as follows. 1. After first intervention, the difference of the FORM-EC item on MCTSIB variable in the vestibuloocular group was significantly decreased(p<.05) and after second intervention, the difference of the FIRM-EO(p<.05), FORM-EO(p<.01), FORM-EC(p<.01) items on MCTSIB variable in the saccadic group and FORM-EC(p<.05) item in the vestibuloocular group were significantly decreased respectively. 2. After first intervention, the difference of the EPE, MXE items in the saccadic group(p<.05) and RT(p<.05), EPE(p<.01) items in the pursuit vergence group were significantly decreased respectively after second intervention. 3. After first intervention, the difference of the Static A-P(p<.05), L-R(p<.01) and Dynamic A-P(p<.01), L-R (p<.01) items on foot pressure variable in the saccadic group, Dynamic A-P(p<.01) item in the vestibuloocular group and Static A-P(p<.01), Dynamic A-P(p<.05), L-R(p<.01) items in the pursuit vergence group were significantly decreased respectively. 4. After first intervention, the difference of the FORM-EO(p<.05), FORM-EC(p<.01) items and after second intervention, the difference of the FIRM-EO(p<.01) item on MCTSIB variable among three groups was significantly decreased respectively. Conclusion:Selective eye movement exercise program influences balance control ability and foot pressure of normal adults in positive ways.

서울대학병원 구강악안면외과의 편평상피세포암으로 진단받은 179명의 증례들을 대상으로 하여 D SAK의 Treatment-dependent prognosis index (TPI)를 기준으로 임상적 요소에 따라 분류하고 치료군과 치료효과에 따른 예후의 지수(index)를 구하여 생존곡선을 산출하고 실제생존곡선과 비교하여 다음과 같은 결과를 얻었다. 1. 임상적 요소의 조합에 따른 48가지의 조합중에서 17종류 조합의 증례들이 해당되었고 E38증례가 가장 많았으며 E44, E37, E14 E39의 순이었다. 결론적으로 D SAK연구와 본 연국의 결과를 비교해보면 D SAK연구에서는 E14, E2등의 초기병기의 환자들이 많고 근원적(radical)한 치료후 완전한 병소의 제거가 이루어진 증례가 많은 반면 본 연구의 결과에서는 E38, E44등 보다진행된 병기의 환자들이 많아 근본적인 치료도 시행되지 못하고 치료후 완전한 병소의 제거가 이루어지지 못한 증례가 많았다. 2. 192가지의 가능한 예후중에서 본 연구에서는 38종류 예후의 index가 해당되었으며, 그 중에서는 E38-B-ED의 증례가 가장 많았고, 그 다음은 E38-A-NED, El4-A-NED, E44-B-ED, E37-A-ED의 순이었다. 3. 본 연구의 생존곡선 비교는 군의 크기가 비교할만큼 크지못해 유의성의 유무에 관해서는 결론을 내리지 못하였으나 E38-B-ED의(Fig. 1) 증례에서는 그 형태가 실제생존곡선과 TPI로 구한 생존곡선이 비슷한 양상을 보였다. 4. D SAK의 TPI의 국내환자들에 대한 적용가능성유무는 모든 그룹별로 환자의 수가 부족하여 생존곡선에 대한 유의성 판정이 불가능하여 국내 구강암환자들의 경우 D SAK연구의 TPI에 의존한 정확한 예후 판정은 불가능하나 각 증례그룹별로 곡선의 형태가 매우 유사한 형태를 보이고 있어 간접적인 예후 추정에 유용할 것으로 사료되며 향후 보다 대단위의 임상적역학조사연구가 진행되어진다면 보다 정확하고 유효한 자료가 될 수 있으리라 추정된다. Applied TNM-system for determination and prognostic classification of the cancer patients of Oral and Maxillofacial region does, however, only partly justice, if at all, to the nature of the tumor disease. And the TNM-system implies among other defects a crude simplification of the complex pattern of the tumor disease. But in clinical practice, the prognosis must be determined on the bases of a specific combination of clinical factors under consideration of various therapeutical conditions. For more reliable and objective prognosis determination for the cancer patients of Oral and Maxillofacial region, Retrospective D SAK(German-Austrian-Swiss Association for Head and Neck Tumors) study introduced Treatment-dependent Prognosis Index TPI in 1982. Treatment-dependent Prognosis Index TPI gives the clinician and opportunity to determine the prognosis before starting therapy at the time of the first admission of the patient, during the therapy and immediately after complete of the therapy. The fundamental purpose of the TPI can be summarized as follows. 1) In clinical-therapeutical cancer research the TPI provides a sound basis for the planning and verification of therapy studies. 2) In clinical practice the TPI allows a reliable and objective determination of the prognosis for the individual patient and thus provides the clinician valuable assistance in planning the treatment. The authors estimated the survival curves of the 179 cases of squamous cell carcinoma from 1985.1.1 to 1992.8.31 in the Department of Oral and Maxillofacial Surgery, Seoul National University Hospital according to Treatment-dependent Prognosis Index TPI of Retrospective D SAK study and compared with the survival curves observed in long term study on prognosis of patients.

본 논문에서는 반도체 포화 흡수체 거울 (SESAM)에 입사되는 단위 면적당 광세기 변화에 따른 이터븀 첨가 광섬유 레이저의 모드 잠금 출력 특성을 고찰하였다. 단위 면적당 광세기를 변화시키기 위해 공진기 내부에 설치된 렌즈의 초점거리를 조절하여 SESAM에 입사되는 광의 크기를 변화시켰다. We investigate the dependence of the output of a mode locked Yb-doped fiber laser on incident intra-cavity intensity on a semiconductor saturable absorber mirror (SESAM). To vary the incident intra-cavity intensity, we change the beam spot size on a SESAM by varying the focal length of a lens installed in the front of the SESAM.

Oral squamous cell carcinoma (OSCC), the most common head and neck cancer, shows poor prognosis as a result of frequent local invasion and lymph node metastasis that is mediated by multiple proteolytic enzymes and angiogenesis. In recent reports, angiogenesis is known to play an important role in tumor invasion and metastasis. The purpose of this study was to determine the role of angiogenesis in OSCCs, particularly with respect to the invasive and the metastatic potential. The microvessel density (CD31) in 34 human OSCC cases were investigated by immunohistochemistry, and reviewed with respect to the invasiveness and the presence of lymph node metastasis and following results were obtained. The blood vessel density (28.8±7.9) in the strong invasive cases were significantly higher than those (23.3±6.9) in the weak invasive cases. (p<0.05) In the 14 cases with lymph node metastasis, the average blood vessel density was 28.5±9.6. On the other hand, in the 20 cases without lymph node metastasis, the blood vessel density was 25.2±6.4. The blood vessel density was not statistically related to lymph node metastasis. (p>0.05) These results suggest that angiogenesis may be related to the local invasion of OSCC and further research will be needed to investigate the possibility that antiangiogenic agent can be used as an anticancer agent for OSCC.

Maritime boundaries are not yet agreed on between Korea and China as well as between Korea and Japan. One of the most important reasons for the growing disputes relating to the boundary delimitation is that the distance between the coasts of any two countries in this area does not exceed 400 nautical miles. The problems of boundary delimitation of the overlapping EEZ shall be the focal point of them. The disputes surrounding Ieodo which is underwater in the assumed EEZ of Korea in the view point of distance are arising, or likely to arise, between Korea and China lately. This paper aims at trying to review conflicting claims of jurisdiction relating to Ieodo between two countries and find countermeasures in international law in particular UNCLOS Convention.

Retinex algorithm, derived from Lands" theory on human visual perception is known to be effective in enhancing the contrast. However, its weaknesses are long processing time and low contrast of bright area in back-light scene because of compensating the details of dark area. In this paper, in order to apply to real-time device, our algorithm is proposed to reduce the processing time and enhance the contrast. Experimental result show that the proposed method yields better performance of color enhancement.

양성골아세포종은 악안면영역에서 발생하는 모든 종양중에서 1% 미만의 매우 드문 종양이다. 또한, 양성골아세포종은 임상적 증상이 특이하지 않으며 다양한 조직상을 보이므로 감별진단은 어려운 문제이다. 이증례는 23세 남자환자의 하악골에 발생한 양성골아세포종에 관한 증례이다. 저자들은 본 증례에서 감별진단을 위해 임상적, 방사선학적, 조직학적 소견에 관해 논의하였으며, 영어로 보고된 논문들 중에서 양성골아세포종으로 나타난 29증례와 본 증례를 같이 분석하여 함께 보고하는 바이다. The benign osteoblastoma is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. Because the clinical feature of benign osteoblastoma is nonspecific and osteoblastoma has a pleomorphic histologic appearance, the differential diagnosis is difficult problem. A case of osteoblastoma in the mandible of a 23-year-old man is reported. We discussed the case from clinical, radiologic, and histologic feature for differential diagnosis. A search of the English language literature revealed only 29 cases that were considered to be osteoblastomas. One case from our clinic is reported and analized with previously described cases.

법랑아 섬유종은 일반적으로 치성 종양으로 분류된다. 이 종양은 상피성및 간엽성 특징을 모두 가지고 있다. 재발된 증례들이 보고되어 왔으며, 재발율은 다양하게 보고 되어왔다. 따라서 수술 방법은 신중하게 고려되어야 한다. 저자 등은 27세된 남자환자의 하악골에서 발생된 법랑아 섬유종 한 증례를 치험하였기에 그 임상적, 조직병리학적 소견에 대하여 보고하는 바이다. The ameloblastic fibroma is generally classified as an odontogenic tumor. It has the characteristics both epithelial and mesenchymal. Some recurrent cases have been reported and the recurrent rate reported variously. So its operative method must be considered carefully. We experienced a case of the 27-year-old patient who experienced recurrent ameloblastic fibroma so report its clinical and histopathologic findings.

이 연구는 대학의 자율성에 대한 정부와 대학 간의 인식 차이를 규명함으로써 일차적으로는 대학의 자율성에 대한 두 주체간의 갈등의 원인을 밝히고, 궁극적으로는 이러한 갈등해결의 실마리를 풀어갈 수 있는 시사점을 도출하기 위하여 실시되었다. 연구대상은 교육인적자원부 및 국ㆍ사립대학 세 곳을 선정하였으며, 연구 자료는 정부 및 대학구성원들을 대상으로 인터뷰를 실시하여 수집하였다. 연구 결과, 정부와 대학 간에는 대학의 자율성 전반에 관하여 상당히 큰 인식차가 있음을 확인하였다. 예를 들면 정부와 대학 간에는 대학의 자율성의 개념에 대한 인식, 정부의 간섭에 대한 인식, 대학의 자율성을 제약하는 수단에 대한 인식 등이 서로 다르다는 것을 확인하였다. 이러한 인식의 차이로 인하여 정부는 나름대로 대학의 자율성을 확대하고자 꾸준히 노력해 오고 있지만, 실제로 대학 구성원들이 느끼는 대학의 자율성은 높지 않음을 알 수 있었다. We explored perceptional differences between government and universities on the institutional autonomy. For this study, we interviewed 11 people: two from Korean Ministry of Education and Human Resource Development, and nine people from three higher education institutions. These 9 interviewees are former high-ranking university administrators, faculty association members, and senior administrative staffs. In the study, we found that there is a considerable perceptional differences between government and universities on conceptualizing institutional autonomy, ongovernmental interventions, and on the ways of governmental intervention. Because of these perceptional differences between the two entities, governmental efforts to enhancing institutional autonomy might not achieve its goals though the Korean government continuously decentralize its legal authority to higher education institutions.

Pigmented villonodular synovitis(PVNS) usually presents as a benign proliferative monoarticular arthritis that affects the knee in 80% of cases, followed in frequency by the hip, ankle, and calcaneocuboid joint. PVNS rarely affects temporomandibular joint area. Patients typically complain of pain, locking, and recurrent swelling. Tumor progression limits the range of movement of the joint and causes it to become stiff and firm. Sometimes a palpable mass can be appreciated. Aggressive form of PVNS invades into adjacent bones and soft tissues, is confused with other types of neoplasia. Here we report 2 cases of the PVNS on a temporomadibular
