최근 국내에서도 사회 주체(주민, 사용자 등) 주도형 혁신모델이자 지역·현장기반형 혁신의 장으로서 리빙랩이 도입·적용되고 있다. 본 연구는 지역사회문제 해결을 위한 실험으로 ‘리빙랩’을 명시하고 추진된 북촌 리빙랩, 성대골 리빙랩, 건너유 프로젝트 3개 사례를 분석하였다. 각 사례의 지역문제, 문제해결 목표, 참여주체 및 주체별 역할, 리빙랩 추진체계, 의의를 분석하고 리빙랩의 유형·특성을 도출했으며, 향후 발전 방안을 모색하였다. 분석 결과 각 사례는 기술 활용 방식과 사용되는 기술의 특성은 차이가 있으나 과학기술·ICT와 지역문제 해결을 연계하고자 했으며 지역주민이 문제 발굴부터 기술 실험 및 확산·적용까지 리빙랩 전반에서 주도적인 역할을 수행하였다. 또한 공통적으로 중간지원조직의 역할이 리빙랩 운영에 중요한 요인으로 작용하였다. 각 사례는 서로 다른 리빙랩 유형을 보이고 있는데, 북촌 IoT 리빙랩은 정부/지자체가 리빙랩 활동기반 조성 또는 행위자 활동을 지원하고 프로젝트 형태로 운영된 반면, 성대골 에너지전환 리빙랩과 건너유 프로젝트는 시민사회 스스로 지역문제를 해결하기 위해 문제를 정의하고 기술을 탐색하는 형태로 진행되었다. Living Lab is being introduced and applied as an innovation model driven by social entities (residents, users, etc.) and as an innovation place based on local and field. This study analyzed three living lab cases of Bukchon IoT living lab, Seong-Daegol energy transition living lab, and Daejeon Geonneoyu project, which were designated as "Living Lab" to solve local problems. We analyzed the local problem, the problem solving goal, the role of each participant and the subject, the living lab promotion system, the significance in each case. In addition, the types and characteristics of living labs were elucidated and future development plans were discussed. The result is as follow. First, each case has a tendency to link science technology and ICT with local problem solving though there is a difference between the technologies used. Second, local residents played a leading role in the whole living lab process from problem identification to technical experimentation, diffusion and application. Third, the role of the intermediaries commonly played an important role in the operation of the living lab. Last but not least, each case has different types of living lab. Bukchon IoT living lab being operated as a project by the government / municipality to create a living lab activity-base or to support actors’ activities. On the other hand, the Seong-Daegol energy transition living lab and Daejeon Geonneoyu project were conducted by the civil society itself to define problems and explore technologies in order to solve local problems.

외상에 의한 치아의 함입은 치아가 치조골 방향으로 변위되어 있는 상태이다. 함입성 탈구는 다른 유형의 탈구성 손상에 비하여 드물게 발생하고, 낙상에 의한 경우가 많으며, 소녀보다는 소년에서 호발하는 것으로 보고되었다. 치아가 함입되었을 때, 치수괴사나 유착, 치근흡수, 근관폐쇄, 변연골 상실 등과 같은 합병증이 발생할 수 있으며, 치아 경조직과 치아 지지조직 등의 손상이 동반되는 경우가 흔하므로, 예후를 예측하고 정확한 진단 및 치료계획을 수립하는데 어려움이 있다. 함입된 치아의 치료는 자발적으로 재맹출하기를 기다리거나, 교정적 견인 또는 외과적으로 재위치 시키는 방법이 있다. 이 증례는 외상으로 인하여 상악 좌측 중절치가 함입되었다는 주소로 내원한 6세 7개월 된 여아에서, 함입된 치아의 자발적인 맹출을 기대하였으나 맹출이 되지 않아서, 교정적으로 견인하여 맹출시킨 경우로 양호한 결과를 얻었기에 이를 보고하는 바이다. Traumatic intrusion is a type of injury that involves axial displacement of a tooth toward the alveolar bone. Its occurance is relatively rare compared to other types of luxation in permanent dentition. It is more common in boys than in girls, and most common etiology of intrusion is fallen down. Various complication may occur following traumatic intrusion, such as pulp necrosis, root resorption, pulp obliteration and marginal bone loss. In addition, traumatic intrusion is commonly combined with hard or soft tissue injuries. Therefore, it is difficult to establish proper treatment plan. Choice of treatment for an intruded tooth by trauma include waiting for spontaneous re-eruption, orthodontic repositioning, and surgical repositioning. In this case, we repositioned the intruded central incisor using orthodontic traction, in a six-year old girl, which failed to re-erupt spontaneously.

혼합 치열기 어린이의 치은 섬유종증

한효정,최병재,김진,김성오,손홍규 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

치은 섬유종증은 유리 치은과 부착 치은이 점진적으로 증식되는 비염증성 질환이다. 대부분 가족력이 있으며 영구치 맹출과 함께 발병하지만 유치 맹출 시기에, 드물게 출생 시부터 나타나기도 한다. 본 6세 여아의 경우 태어날 때부터 치은의 일부가 증식되어 있었고 가족력 및 치은 증식을 유발하는 약물을 복용한 병력은 없었다. 구강 내 검진 시 섬유성 치은 증식이 관찰되어 절제 생검을 시행하였고 그 결과 치은 섬유종증으로 진단하였다. 치은 섬유종증의 치료는 치은 절제술과 철저한 구강 위생의 관리이다. 그러나 치료 후 재발성 때문에 치료 시기에 대해서는 논란 중이다. 일반적으로 영구치가 모두 맹출 한 이후에 치료할 것을 추천하지만 조기 치료는 구강의 기능 및 환아의 심미적, 심리적인 문제점을 개선시켜 주는 장점이 있다. Gingival fibromatosis is a non-inflammatory oral disease, characterized by slowly progress enlargement of the free and attached gingiva. Gingival fibromatosis may have familial tendency. Gingival enlargement usually begins with the eruption of the permanent dentition but can also develop with the eruption of the primary dentition. In this case, a 6-year-old female had gingival enlargement at birth. There was no familial, medical and pharmacologic history of gingival overgrowth. Treatment is gingivectomy with a rigorous program of oral hygiene. Recurrence of gingival fibromatosis may well be inevitable. Therefore there is no general aggrement as to the timing of surgical intervention. Generally the best time is when all the permanent teeth have erupted. However early intervention can improve oral function and esthetic and psychologic effect.

The purpose of this study is to develop a inquiry learning instrument and to evaluate the effectiveness of experiment in the concept-forming about mapping and interpretation of the geological map. Unfortunately no proper experimental instruments on the content of this study has been utilized in the current domestic Earth Science textbooks. In this study, the geological structure models with 4 different dips were developed. In order to evaluate the effectiveness of the experiment, we prepared a test consisted of 10 problems and compared the test results performed by the control group who conducted the experiments along with regular class with another test results performed by comparative group who participated only regular class without experiment. The control group is consisted of 102 girls high school students in Taegu area, and the comparative group is 104 students. The test results are as follow : ⅰ)The mean of the test results of the control group (X_A) is 7.18, while that of comparative group(X_B) is 6.38. ⅱ)The difference of the test scores between two groups has been turned out to be highly significant at the 0.05 level of significance. (t=3.270 at the criterion for significance, α=0.05 and the degree of freedom, df=206). This suggest that the class learned by the experiment is more effective in the concept-forming of the making and interpretation of the geological map than the class only learned by lectures.

국내 해안에 퇴적한 실트질모래와 hydraulic fill한 지반에서 채취한 시료의 액상화강도 측정을 위해 응력제어 반복삼축압축시험을 수행하였다. 이를 위해 1)불교란시료와 교란시료의 액상화강도 산정과 2)등방압밀된 시료와 비등방압밀된 시료의 반복삼축시험결과 비교, 3)본 시험결과와 국내 다른 시험자료 및 외국의 결과를 비교하였다. 불교란시료의 경우 반복횟수 N이 10회 일 때 액상화강도는 교란시료에 비해 약 두 배 정도 크게 나왔다. 비등방압밀된 시료의 액상화강도는 수직응력을 구속응력으로 나눈 유효압밀비에 영향을 받는다. 유효압밀비가 증가함에 따라 액상화 강도는 증가하여, 유효압밀비가 1.2와 1.5인 경우 유효압밀비가 1인 경우보다 각각 24%와 56% 정도 증가되었다. 본 시험결과는 국내 다른 연구자들의 시험과 비교했을 때 같은 상대밀도에서 약간 큰 경향을 나타냈으며, Seed and Idress(1971)가 제안한 입경별 액상화강도 추세선으로 비교하였을 때도 약간 큰 강도를 보이고 있다. Dynamic triaxial tests were performed in order to evaluate the liquefaction potentials of silty sands and hydraulic fill ground. In the tests, (1) undisturbed and disturbed samples were prepared for the tests, (2) dynamic shear strengths were measured under isotropic and anisotropic condition and (3) the test results were compared with the other results which were tested by domestic and foreign researchers. The test results of undisturbed samples showed the dynamic shear strength twice larger than those of disturbed samples at the 10 cycles loading. The dynamic shear strength of anisotropically consolidated samples were affected by the effective consolidation ratio which is the rate of vertical effective stress divided by confining stress. The dynamic shear strength at the effective consolidation ratio of 1.2 and 1.5 increased by 24% and 56%, respectively, comparing to the strength at the ratio of 1. These test results showed that the dynamic strengths were a little larger than those of other domestic researchers, and Seed and Idress(1971).

접합면의 차이에 따른 두개골 외판의 생존

Onlay graft of the calvarial bone has been popularized in craniofacial surgery because absorption of the calvarial bone is less than that of the endochondral bone. But the problems with using the calvarial bone are its rigidity and difficulty in setting a precise apposition. When the outer tables of the calvarial bone are used for augmentation and reconstruction of the convex zygoma, forehead, or chin, it is better to place the cancellous surface over the convex recipient bone to get a precise apposition. Whereas, it is better to place the cortical surface over the concave nose or orbital cavity to achieve a good apposition. Therfore, our study was designed to determine the differences of bone absorption and regeneration between cancellous and cortial bone contact to facial bone, and between preserved periosteum and detached periosteum in autograft of calvarial bone in dog models. Outer tables of the calvarial bone were placed in subperiosteal pockets of the upper and lower maxilla in four different ways : Group I ; The cancellous surface was placed in contact with the bare recipient bone, and the cortical surface attached with periosteum was accordingly contacted with the elevated periosteum of the recipient bone. Group Ⅱ ; The corical surface attached with periosteum was placed in contact with the bare recipient bone and the cancellous surface was contacted with the elevated periosteum of the recipient bone, Group Ⅲ ; The arrangenent was similar to Group Ⅰ except that the periosteum of the graft was deprived. Group Ⅳ ; The arrangement was similar to Group Ⅱ except that the periosteum of the graft was deprived. Volume measurements using a caliper technique and histological study were made 20 weeks postoperatively. The volume of maintenance is as follows ; Group Ⅰ, 84.2% ; Group Ⅱ, 77.6% ; Group Ⅲ, 77.0%, and Group Ⅳ, 69.5%. The histolgical contribution of living bone was assessed by a modified point counting technique : Group Ⅰ, 86.6%, Group Ⅱ, 83.8% ; Group Ⅲ, 79.6% and Group Ⅳ, 77.6%. Greater volume maintenance and histological contribution of living bone were found when cancelllous surface rather that the cortical were placed in contact with the recipient bone and the grafts from their periosteum were preserved. We concluded that in order to expect better survival of a grafted bone, the cancellous surface of the graft should contact with the recipient bone and that the periosteum of the graft should be preserved.

Difficulties arise in prediction of maintenance of the graft volume and viability of graft over time when a bone graft used for facial reconstruction. A bone-to-bone contact between the graft and the recipient bone is imporant for creeping substitution and survial of the recipient bone is important for creeping substitution and of the grafted bone. An adequate blood supply is also essential to ensure the survival of any live cells of the surface of the graft. Our study was designed to determine which one is an important factor viability of the grafted bone in Korean adult dogs : a bone-to-bone contact or overlying soft tissue. Blocks of outer table of the parietal bone were placed at the maxillae subperiostially in 4 different ways : bone-to-bone contact groups(groups Ⅰand Ⅱ)with placing a silicone membrane over the grafted bone and soft tissue contact groups(groups Ⅲand Ⅳ)with placing a silicone sheet between the grafted bone and the recipient. In groups Ⅰand Ⅲ, the cancellous surfaces of the parietal bone was placed on the recipient and the cortical surfaces were placed on the recipient in groups Ⅱ and Ⅳ. Caliper techniques were used to study the rates of volume maintenance of the grafts at 6, 12, and 20 weeks after bone grafting. The volumes of the living bone were quantified microscopically using a modified point-countiong technique. The volume is reduced in a similar rate with time in all groups. At 6 week, living bone cells increased in soft tissue contact groups Ⅲ and Ⅳ however, and increased in bone to bone contact groups Ⅰand Ⅱ at 12 and 20 weeks. there were osteoblastic proliferation and laminated mature bones in group Ⅰand Ⅱ. But osteoclasts and their associated osteolytic changes were still seen near the silicone membrane in group Ⅲ and Ⅳ, which may imply a continuing resorptive process with time. In summary, revascularization from the overlying soft tissue is important for the graft survival in early stage of the bone grafting while bone-to-bone contact may be essential in a later stage.
