In general, forecast tsunami heights announced for tsunami warning are computed by using a linear tsunami model with coarse grids which leads the underestimation of inundation area. Thus, an accurate tsunami inundation map corresponding to the forecast tsunami height is indispensible for an emergency evacuation plan. A practical way to construct a relatively accurate tsunami inundation map was proposed in this study for the quantitative forecast of inundation area. This procedure can be introduced as in the followings: The fault dislocations of potential tsunami sources generating a specific tsunami height near an interested area are found by using a linear tsunami model. Based on these fault dislocations, maximum inundation envelops of the interested area are computed and illustrated by using nonlinear inundation numerical model. In this study, the tsunami inundation map for Imwon area was constructed according to 11 potential tsunami sources, and the validity of this process was examined.

The mineralized collagen fibrils and tablet-like crystals were observed in the murine femoral trabecular bone, which appeared to have more of a random arrangement with the crystal orientation changed within an approximately 100 nm. The presence of the continuous (002) ring indicates that the c-axis of crystals is mostly parallel to the section and the directions of the c-axis are relatively random with no preferred orientation. The distribution and orientation of mineral apatites in the murine trabecular bone was found to be different from those typically observed in the lamellar bone and the difference can be attributed to the more complex local stress state in the trabecular bone. It was also shown from dark field image analyses that apatite crystals are not single crystalline, but multi-crystalline. This observation is compatible with the suggestion that the formation of a large platelet was attained by joining independent nuclei. The small round crystalline particles (2 nm in size with the lattice fringe lines of 0.28 nm in spacing) observed near or at tip of collagen fibrils were likely to be apatite nuclei nucleated independently. A small misorintation angle between adjacent nuclei can be linked with the multi-crystallinity of apatites observed in the present study.

이 논문은 제주 섬 사람들의 난민에 대한 인식을 확인하기 위하여 제주대학교 생명윤리위원회의 IRB 승인으로 2020년 11월에 진행한 설문조사 결과를 분석하였다. 설문조사의 모집단은 제주에 거주하는 만19세 이상 성인 남녀 540,903명이다. 99%의 신뢰도 수준에서 허용 표집오차 ± 5%p를 설정하여 읍·면·동 별·성별로 5세급간 연령대별로 비례층화 표집틀을 작성하고 읍·면·동지역을 방문하여 무작위 면접으로 설문조사한 표본사례들 중에서 최종 523 사례를 분석대상으로 선정하였다(99% 신뢰도 수준 ±5.638%p, 95% 신뢰도수준 ±4.283%p). 분석결과, 난민에 대한 제주도민의 기본 태도는 난민법을 존중하고 준수하면서 엄격한 심사를 통해 수용하자는 입장인 것으로 나타났다. 자신의 정치성향이 진보적이거나 경제 상황이 어렵다고 생각하는 계층이 난민 유입에 보다 호의적이고, 보수적이거나 경제 상황이 양호하다고 생각하는 계층은 난민 유입에 훨씬 민감하게 반응하고 적극적으로 반대하고 있었다. 선행연구의 전국조사와 비교하였을 때 시간의 흐름에 따라 난민에 대한 인식이 호의적으로 변화하고 있었으며, 직접 접촉함으로써 난민에 대한 인식이 무조건적인 반대보다 제도적·적극적인 찬성이 더 커진다는 점을 확인할 수 있었다. 전국조사에 비해 제주지역이 난민에 대해 보다 호의적인 차이에 대하여 제주의 쿰다문화에서 비롯된 것이라는 해석의 가능성을 제시하였다. This paper analyzes the results of a survey on the Jeju Islanders' perception of refugees conducted in November 2020 with the approval of the Jeju National University Institutional Review Board. The population of the survey was 540,903 men and women over the age of 19 living in Jeju. By setting an allowable sampling error of ±5%p at the 99% confidence level, a proportional stratified sampling frame was created for each 5 years age group by gender in each eup, myeon, dong area. And a random interview was conducted by visiting the eup, myeon, dong areas. The final 523 cases were selected for analysis (allowable sampling error of ±5.638%p at the 99% confidence level, ±4.283%p at 95%). As a result of the analysis, it was found that the basic attitude of Jeju residents toward refugees is to respect and comply with the refugee law and accept it through strict screening. The class who thought their political inclinations were progressive or their economic situation was difficult was more favorable to the influx of refugees, and the class who thought their political inclinations were conservative or their economic situation was good responded more sensitively and actively opposed the inflow of refugees. Compared with the nationwide survey of previous studies, it can be confirmed that the perception of refugees was changing favorably with the passage of time, and that the recognition of refugees through direct contact increases institutional and active support more than unconditional opposition. And also the possibility of interpretation was suggested that the Jeju islanders influenced by Cumda Culture of Jeju are more favorable to refugees than the general Korean.

본 논문에서는 차량 내의 네트워크 가운데에서 대용량의 멀티미디어 데이터를 전송할 수 있는 MOST(Media Oriented Systems Transport) 네트워크 기반의 오디오 인포테인먼트 인터페이스 개발에 관한 연구를 수행하였다. 구현한 오디오 인포테인먼트 인터페이스는 MOST 네트워크 인터페이스 컨트롤러로 OS81050A INIC 칩을 사용하였으며, EHC 부분은 ATmega128L 8bit 마이크로컨트롤러를 사용하였다. 오디오 동작과 관련된 기능 블록(FBlock) 및 애플리케이션 작성에는 NetServices API를 활용하였다. 구현된 인터페이스는 MOST 네트워크 분석 도구인 OptoLyzer G2를 이용하여 정확한 동작여부를 확인 하였다.

N/A Objectives: Mediastinal tumors are not uncommon but almost half of them are asymptomatic because of the potential space of the mediastinum. Recently owing to the routine screening chest roentgenography and frequent chest CT scans the incidence have increased. Mediastinal masses are both benign or malignant. Even benign masses may continue to enlarge and compromise vital organ function or rupture, bleed, and become infected. Mediastinal tumors have their own predilection site. There are different incidences of these masses in adults and children, sexes, and there may be difference in incidence between races. There are only a few reports about these tumors in Korea, and we are interested in the clinical manifestations of mediastinal tumors in Korea, Methods: We retrospectively reviewed medical records of 286 cases of mediastinal tumors which were pathologically confirmed at Keimyung, Kyungpook, and Yeungnam University Hospital in Taegu from 1985 to 1994 but excluded metastatic lesion, tuberculosis, and tumor originated from esophagus, heart, and large vessels. Results: Mediastinal tumors were more frequent in male(60.8%) than female and age distribution was relatively even. Thymoma was most common mediastinal tumor(107 cases, 37.4%). The most common tumor in anterior mediastinum was thymoma (107/212, 50.5%). In posterior mediastinum, neurogenic tumor was the most common(52/67, 77.6%) and teratodermoid tumor was common in middle mediastinum(3/7, 42.9%). The most common symptom was chest discomfort(129 cases, 45.1%) and 67 cases were asymptomatic(23.4%). Benign tumors were more common(175 cases, 61.1%) than malignant tumors. In therapies, complete or partial resections were done in 190 cases(79.8%), chemotherapy or radiotherapy in 71 cases(29.8%), in 24 cases(10.1%) only biopsy was taken without any treatment. Neurogenic tumors have been reported as the most common tumors in western countries and neurogenic and teratodermoid tumor were found to be the most common tumors in the past Korean reports. But thymoma was the most common tumor in this study. Conclusion: Thymoma was the most common mediactinal tumor in this study. And thymoma was the most common tumor in anterior mediastinum neurogenic tumor in posterior rnediastinum and teratodermoid tumor in middle mediastinum
