이 연구는 문헌 및 현장조사를 통해 동강유역 생태·경관보전지역의 지형·경관 자원을 조사하고 지도화 하였다. 이를 통하여 지형·경관 자원의 분포특성을 살펴보고 동강유역 생태·경관보전지역의 지형·경관자원에 대한 지속적인 관리방안 및 보전방안을 제시하고자 하였다. 연구결과 본 연구지역은 동강 양안의 하천지역 지형·경관자원과 평창군 한탄리의 고원형 카르스트지역 지형·경관자원, 연구지역 전역에 걸쳐 대소로 분포하는 석회동굴 지형·경관자원, 연구지역 경계의 산지지역 지형·경관자원 등 크게 4개의 지형·경관자원으로 분류할 수 있었다. 이들 지형·경관자원은 현재 관광객의 유입과 거주민의 편의성 확보를 위해 일부 훼손되거나 훼손압력이 높은 것으로 조사되었다. 따라서 1일 탐방객을 제한하거나 학술적 의미를 담은 안내판 설치와 같은 지형·경관 자원의 보전과 주민이익이라는 공동 이익 추구를 위하여 지형·경관 자원별로 맞춤식 보전대책이 필요할 것으로 판단된다. This study has focused on geomorphological landscape resources analysis at the Dong-gang River Ecological and Landscape Conservation Area through literature review and field survey. Some appropriate maps have been created for this study. This study intends to examine the distribution characteristics of geomorphological landscape resources at the Dong-gang River Ecological and Landscape Conservation Area, and suggests a solution to manage and maintain the resources. The result has shown that the resources can be divided into four categories : The Dong-gang`s riverside geomorphological landscape resources, Pyeongchang-gun Hantan-ri`s plateau and karst area, limestone caves in various sizes throughout the entire study area, and the mountainous regions close to the study area boundaries. The study concluded that these geomorphological landscape resources are partially damaged or likely to be damaged due to tourist inflow and also the quality of resident lives needs to be improved. Therefore, limiting the number of tourists entering the area or installing guides who provide information about the academic importance of such resources are necessary in terms of maintenance. There is also a need for a customized solution according to geomorphological landscape resources in order to secure benefits for the residents as well.

During the condylar shaving procedure, the articular soft tissue cover can be removed. Author compaired the histological healing process of the articular soft tissue cover between the preservative and unpreservative group group with 45 New Zealand rabbits(Average wt. : about 2.5kg). In unpreservative group, the usual high condylar shave with the removal of soft tissue cover was performed. In the preservative group, the underlying bone, replaced in its original position and sutured. The animals were sacrified 1, 2, 3, 4, 6 weeks interval after operation. The specimens were fixed in 10% neutral formalin and decalcified, paraffin embedded and stained by Hematoxylin & Eosin, and Masson's trichrome. The obtained results were as follows. 1. The condyles of the both group were covered with an articular sop tissue layer. 2. The cartilage cells in subarticular layer has regular continuous patterns in the preservative group but frequently interrupted in the unpreservative group. 3. The incision made in the posterior part of the articular surface for the elevation of the articular soft tissue frequently caused a deformity such as the interruption of the subarticular layer of cartilage. 4. By the above findings, the preservation of articular sop tissue cover may be the effective operation method on concept of bone remodelling.

The crystallinity, crystallite sizes and orientation of hemp fibers treated in caustic soda of various concentration with and without constraint were measured by wide angle X-ray diffraction method. It was found that, 1) The crystallinity monotonously decreased with the increase of caustic soda in the samples treated with constraint, whereas it decreased and again increased with the increase of alkali concentrations in the samples treated without constraint. 2) Crystallite sizes of 002 plane decreased with increase of alkali concentrations, more remarkable decrease occured in the samples treated with constraint, And there were no significant changes on the crystallite sizes of 040 plane in the samples treated with and without constraint. 3) The orientation increased in the samples treated with constraint, whereas it decreased in the samples treated without constraint. The foregoing observations indicate that it is advisible to avoid high alkali concentration and excess tension.

본 연구는 공주지역의 지표변화를 분석하기 위해 우도비 기반의 베이지안 예측모델을 이용하여 지리공간 정보와 지표변화와의 연관성 및 미래의 지표변화를 탐지하였다. 지표변화 지역은 위성사진을 토지피복분류 한 후 선분류 후비교법을 이용하여 변화지역을 추출하였다. 지표변화와 관련이 있는 지리공간 정보는 GIS 환경에서 구축하였으며, 우도비를 이용하여 지표변화 예측도를 작성하였다. 분석결과, 도시지역 및 농업지역 지표변화에 가장 큰 영향을 미치는 주제도는 고도, 하계망, 인구밀도, 도로, 인구이동, 총사업체수, 지가 등이다. 또한 산림지역 지표변화에 영향을 미치는 주제도는 고도, 경사도, 인구밀도, 인구이동, 지가 등이다. 지표변화 분석결과, 도시지역은 금강을 중심으로 구도심과 신도심지역의 도시 확산이 이루어지고, 인터체인지 및 국도를 따라 시가화 지역이 확산 될 것으로 예측되었다. 농업지역은 금강의 소지류 및 인접지역과 연결되는 국도주변 지역이 변화가 일어날 확률이 높다. 산림지역은 대부분 남동쪽에 위치하고 있는데, 그 원인은 밤나무 재배단지가 본 지역에 넓게 나타나면서 산림훼손이 일어날 확률이 높은 것으로 예측되었다. 예측비율 곡선을 이용하여 검증한 결과, 지표변화가 일어날 확률이 가장 높은 상위 10%지역에서 도시지역은 80%, 농업지역은 55%, 산림지역은 40% 정도의 예측능력을 보였다. 따라서, 본 통합 모델은 산림지역 예측에는 부적합한 것으로 볼 수 있어서, 향후 새로운 주제도 선정 및 예측모델 등이 필요하다. 결론적으로 본 방법은 향후 토지피복 변화 연구를 위한 효과적인 방법 중의 하나로 적용될 수 있을 것으로 기대된다. In this study, we investigated the change of future land-surface and relationships of land-surface change with geo-spatial information, using a Bayesian prediction model based on a likelihood ratio function, for analysing the land-surface change of the Gongju area. We classified the land-surface satellite images, and then extracted the changing area using a way of post classification comparison. Land-surface information related to the land-surface change is constructed in a GIS environment, and the map of land-surface change prediction is made using the likelihood ratio function. As the results of this study, the thematic maps which definitely influence land-surface change of rural or urban areas are elevation, water system, population density, roads, population moving, the number of establishments, land price, etc. Also, thematic maps which definitely influence the land-surface change of forests areas are elevation, slope, population density, population moving, land price, etc. As a result of land-surface change analysis, center proliferation of old and new downtown is composed near Gum-river, and the downtown area will spread around the local roads and interchange areas in the urban area. In case of agricultural areas, a small tributary of Gum-river or an area of local roads which are attached with adjacent areas showed the high probability of change. Most of the forest areas are located in southeast and from this result we can guess why the wide chestnut-tree cultivation complex is located in these areas and the capability of forest damage is very high. As a result of validation using a prediction rate curve, a capability of prediction of urban area is 80%, agriculture area is 55%, forest area is 40% in higher 10% of possibility which the land-surface change would occur. This integration model is unsatisfactory to predict the forest area in the study area and thus as a future work, it is necessary to apply new thematic maps or prediction models . In conclusion, we can expect that this way can be one of the most essential land-surface change studies in a few years.

The purpose of this study is to analyze the geomorphological environment changes of tidal flat in the Cheonsu Bay. Especially, it centers on the changes in the sedimentary environment using remote sensing data. Multi-temporal Landsat data and topographic maps were used in this study. The results are summarized as follows: the tidal flat of Cheonsu Bay changes in many ways depending on the direction of the tidal current. In the neighborhood of Ganwoldo, the scale of the tidal flat has continuously been expanded due to the superiority of sedimentation after a tide embankment was built. When we analyzed the grain size of sediments and implemented in-situ field survey, it was found that the innermost part of the bay consists of a mud flat, with the midway part mixed flat, and the nearest part to the sea sand flat. On the other hand, in the neighborhood of Seomot isle and its beach, sedimentation is superior in the eastern part whereas erosion is superior in the western part. In other words, the western coast of the beach is contacted with the open seas and under much influence of ocean wave. The eastern coast is placed at the entrance of the bay and has sand bar and tidal flat developed due to submarine deposits that are accumulated on the sea floor by the tidal current. In conclusions, remote sensing methods can be effectively applied for quantitative analysis of geomorphological changes in tidal flat, and it is expected that the proposed schemes can be applied to another geomorphological environments such as beach, sand dune, and sand wave.

이 연구에서는 토지지목 자료를 이용하여 서산시의 토지지목별 변화를 탐지 및 예측하고, 고해수면 복원자료 및 IPCC SRES 시나리오를 바탕으로 해수면 상승에 따른 침수취약성을 평가하였다. 토지지목 예측 방법은 이중지수 평활법을 사용하였다. 연구결과, 토지지목 자료를 이용한 시계열분석에서는 논과 인공구조물, 수역, 초지, 나대지 등이 증가하였고, 반면에 산림지, 습지, 밭 등은 감소하였었다. 이중지수 평활법을 이용한 토지지목변화를 예측한 결과, 2010년에서 2050년까지 산림지, 초지, 습지, 논, 밭의 경우 지속적으로 감소하는 반면, 수역, 인공구조물, 나대지는 계속해서 증가하는 경향을 보였다. 침수 취약성 평가에서는 인공구조물과 논, 밭, 나대지 등은 침수 피해 면적이 증가하는 반면에 산림지, 수역, 습지 등은 침수 피해 면적이 감소하는 것으로 분석되었다. 특히 농경지와 인공구조물의 침수 위험성이 증가하는데 비해, 습지, 산림지의 침수 위험성은 감소하였다. 이러한 침수 면적의 증가 및 감소 원인은 해안지역에서 이루어지고 있는 관광지 개발과 산업단지 건설 등에 따른 산업화·도시화 등의 토지이용 변화에 따른 것이다. In this study, we detected and predicted changes in terms of land categories of Seosan-si using land category data. We also evaluated flood vulnerability due to the rise in sea level based on the past sea level recovery data and IPCC SRES scenario. As a method of predicting land category, this study applied the double exponentially smoothing method. Results of the time series analysis using land category data revealed that paddy, artificial structure, water, grass field and bare land areas increased, but forest, marsh and dry field areas decreased. The results of predicting changes in land category using double exponentially smoothing showed that forest, grass field, marsh, paddy and dry field areas will continue to decrease from 2010 to 2050, but water, artificial structure and bare land areas are expected to increase continuously. Through flood vulnerability assessment, it was analyzed that flood-affected areas in artificial structure, paddy, dry field and bare land areas increased, but those in forest, water and marsh areas decreased. In particular, the risk of flooding in agricultural land and artificial structure increased, but that in marsh and forest areas decreased. It is estimated that the increase and decrease in inundation areas is caused by changes in land use resulting from industrialization and urbanization due to the construction of industrial complexes and development of tourist resorts that takes place in coastal areas.

Transforming growth factorβ (TGB-β) is a potent modulator of proliferation and differentiation in bony tissue, and might have a role in the control of bone formation and remodeling. Monitoring these pattern of genes and protein expression during tumor development will provide a basis for understanding normal growth and distortion of osteochondrogenesis. The expression and distribution of TGF-βwas studied in 34 bone tumors that consisted of odontogenic myxoma 3 cases, osteoma 5 cases, exostosis 4 cases, chondrosarcoma 3 cases, osteosarcoma 4 cases, fibrous dysplasia 4 cases of mandible cementossifying fibroma 4 cases, ossifying fibroma 4 cases, malignant fibrous histiocytoma 3 cases. And normal bone was used for standardization of the expression and distribution of TGF-β. In order to analyze the expression of TGF-β in the tumor types, immunohistochemical stain was performed with TGF-β as a primary antibody and anti-mouse IgG as a secondary antibody. Results about interrelationship between TGF-βexpression and bone tumor as follows with immunohistochemical stain for TGF-β: TGF-βexpression was mild in osteoblast of normal bone and negative in bone matrix, TGF-βexpression in osteoma was more increased than normal bone and exostosis. TGF-βexpression was negative in fibroblast of cementifying fibroma and ossifying fibroma. TGF-βexpression was moderate in cementoblast and osteoblast and cementocyte or osteocyte of cementifying fibroma and ossifying fibroma. TGF-βwas the most expression fibrous dysplasia but especially woven bone and fibroblasts in interlacing collagen fiber. Especially, it seems that strong of TGF-βin fibrous dysplasia due to coupling effect of bone resoprtion and subsequent bone formation. TGF-β expression was negative in fibroblast and histiocyte of malignant fibrous histiocytoma. TGF-βexpression was negative in inner fibrous tissue of osteosarcoma, moderate in osteoid of osteosarcoma and mild in atypical osteoblast. TGF-βexpression was severe in nuclear and cytoplasm of atypical cartilage cell and cartilaginous cell matrix. of chondrosarcoma, and negative in fibrous intercellular tissue of osteosarcoma. In summary, the expression of TGF-β in the bone tumor is more than that of normal bone. And it has a difference between benign and malignant tumors. It should be consided that TGF-βis one of prognostic factors in bone tumor.
