  • The objective of this study is to propose a methodology of the flood runoff analysis in steep mountainous basins and the analysis basin is the Jasa valley basin in Chungju city Analyzing the spatial pattern of the rainfall in 1994. 6 30~7.1, the seasonal rainy front was tied up in the whole central district, and the rainfall center was moving from the northern Chungbuk province to the northern Kyongbuk province and caused heavy storm. Analyzing the temporal pattern with the Huff method, the 52.5% of the rainfall was concentrated on the 3rd quartile. Rainfall frequency analysis is accomplished by five distribution types; 2-parameter Lognomal, 3-parameter Lognomal, Pearson Type III, Log-Pearson Type III and Extremal Type I distribution Rainfall-runoff analysis in Jasa valley basin was made using HEC-HMS model. Jasa valley basin was divided into 3 sub-basins and the analysis point was 3 points{A, B and C point) With the rainfall data measured by the 10 minutes, the flood runoff also was calculated by as many minutes. SCS CN model, Clark UH model and Muskingum routing model in HEC-HMS model were used to simulate the runoff volume using selected rainfall event.

  • A large anorthositic mass outcropped as mushroom-like body extending up to 46km which occurs in the Hadong kaoline district of southern Korea. The anorthositic mass is in contact with the metamorphic, plutonic and sedimentary rocks. The metamorphic rocks are of granitic gneiss and banded gneiss, etc; the plutonic rocks are of gabbroic and dioritic rocks, schistose granite, syenite, diorite and granite. The sedimentary rocks include siltstone and pebbly sandstone of Lower Gyeongsang System, Cretaceous in age. The anorthositic mass shows a gradational contact with the metamorphic and sedimentary rocks, and is cut by the plutonic rocks except gabbroic and dioritic rocks. The anorthositic mass is leucocratic in the central portion of the mass, and, in turn, grades to rock phases in which ma/ic minerals are irregularly scattered, then to the well-lineated rock and finally to the banded gneiss. Lineation of the anorthositic mass is accordant with that of the surrounding banded gneiss, and the lineation continues toward the gneiss. In some places, the rock phases in which mafics are scattered is gradational with adjacent sedimentary rocks. The anorthositic mass in contact with gabbroic and dioritic rocks shows spotted features. Various replacement features seen under the microscope and paragenetic sequence of the mineral components in the anorthositic rocks cannot be considered as the origin of magmatic crystallization. From the field and microscopic observations, it is concluded that the anorthositic mass was formed from replacement of the metamorphic rocks and plutonic rocks by the anorthositic magma.

  • Myanmar(Burma) has been preserved valuable environmental resources because of its political isolation. But recently, Myanmar has moved a capital city(Naypyidaw) at central forest area and it has been urbanized radically since 2005. In this paper, we built multi-temporal land cover map from Landsat images of 1970s to 2012 with ENVI 4.5 software. For a broad approach, administrative district Yamethin which includes Naypyidaw is classified into 3 classes and with only Naypyidaw region is classified with 4-5 classes to analyse specific changes. And with forest cover extracted by Object Oriented Classification, we evaluated forest fragmentation before and after the development using Patch Analyst(FRAGSTATs 3.3) at Yamethin area. For Yamethin area, there were significant forest cover change, 51% in 1999 to 48% in 2012, and for Naypyidaw area, 67% in 1999 to 57% in 2012 respectively. Also landscape indices resulted from Patch Analyst concluded that the total edge, edge density and mean shaped index of forest patches increased and total core area is decreased. It is attributed from land cover change with urbanization and agricultural land expansion.

  • This article aims at demonstrating location specific approach for agricultural technology promotion and adoption in improving the livelihood of the small farmers in the haor basin and coastal belt of Bangladesh. Innovative technologies that have potentials are initially screened by ex-ante investigation and instrumented by the business model canvas, which is used as a bottom-up approach for sustainability of the adoption of proposed technology innovations. Village-level extension farmers, sub-district extension officers and farmers' cooperative are the unique and central features to the business models and forward linkages. Extension service, power tiller, low-lift pump, sunflower, shallow tube well, quality seed, forward linkage for farmed duck eggs, live ducks and open catch fish etc. are the suggested potential technology innovations for the small farmers. The technology adoption business model can be reinvented for different locations within or beyond the country considering the local agricultural problems and prospects for greater sustainability.

  • The maintenance cost plays a important role to plan the scale of the apartment housing such as a number of household, building area and building type. Therefore, it is required to forecast the cost considering various maintenance characteristics. The maintenance characteristics are floor area, number of household, heating type, site area and etc.. In addition, the maintenance cost are classified into 5 area. These are a personal expense, facility maintenance cost, energy and water cost, insurance and sanitary cost. These five cost area are related with various characteristics and brought up the estimation model using the stepwise multiple regression analysis. The energy and heating cost share over the 50% in the total cost and the personal expense cost shares about 40%. The personal expense cost per area is 5,272 won/$m^2{\cdot}yr$ irregardless of heating type and the district heating type is a higher cost than other type. In facility maintenance cost, the central heating type is 2,015 won/$m^2{\cdot}yr$ and higher than other type. The estimation models have good statistics in each model. Most of the model have a determination coefficient over 0.7 and Durbin Watson value between 1.5 and 2.5.

  • 도시화로 인해 도심지와 도시외곽간의 기온차가 더욱 심해지는 열섬현상은 폭염과 더불어 도시민의 쾌적한 삶을 저해하는 요소로 작용하여 이를 저감하기 위한 노력이 시행되고 있다. 도시 기온은 도시의 지형적 특성, 도시 수체의 규모와 위치 등에 의해 영향을 받고 있는 것으로 알려져 있어 도시외곽에 산림이 존재하는 도시에서는 이들 지역과 도심지와의 기온차이를 측정하여 바람길을 이용한 기후응용도시계획에 활용할 필요가 있다. 허나, 아직 국내에서는 이들 기온 차에 대한 특성을 조사한 연구가 많지 않다. 이를 위해 본 연구에서는 서울시 강남 지역을 대상으로 도심지 상업업무중심지구 두 곳(GNS, SLS)과 도시외곽 산기슭 마을 두 곳(YGD, GPT) 간의 기온 차를 2008년 4월 14일부터 2009년 4월 13일까지 1년간 관측한 자료를 대상으로 일 변동, 계절별 변동을 비교, 분석하였다. 분석결과 관측 기간 동안 YGD는 연평균기온이 GNS보다 $2.8^{\circ}C$ 낮았으며 열대야는 GNS, SLS가 16일인데 비해 GPT는 2일, YGD는 하루도 관측되지 않아 도시외곽의 산림이 도시기온 저감효과가 있음을 확인하였다.

  • This study was conducted to estimate the future government budget in medical expenditures using for the low-income handicapped, because medical expenditures to the low-income handicapped is escalating in these days. It became a big problem not only to the central-government but also to the district-government because they have to subsidize a part of co-payment. This study was designed to project the future government budget using structural model. For the short-term projection, the structural model is stronger than the regression model. The data used for this study were the population projection data based on National Census Data(2000) of the National Statistical Office, the data of Ministry of Health & Welfare, and the data of National Health Insurance Corporation from November 2m to June 2001. The results of the study are summarized as follows: The future government budget in medical expenditures using to the low-income handicapped will be 15-18 billion Won in the year 2003, 16-23 billion Won in 2004, 18-30 billion Won in 2005, 19-38 billion Won in 2006 and 21-49 billion Won in 2007. It is predicted that they would be increasing rapidly. Therefore, the government budget in medical expenditures using for the low-income handicapped must be enlarged.

  • In medical malpractice lawsuits, negligence is generally defined as conduct that is culpable because it falls short of what a reasonable person would do to protect another individual from a foreseeable risks of harm. Thus, the essence of negligence is a breach of obligations to be attentive, and the breach of obligations to be is negligence. However, whether negligence is or not depends on time, place, litigation forms and the judge since the meaning of negligence is wavering on the basis of abstract and normative judgment. In this thesis, what is medical negligence, a breach of obligations of attention for a doctor in medical malpractice lawsuits, would be it further enacted that doctors have the responsibility to protect the patients as a subordinate duty due to a principle of faith and sincerity besides the main duty for medical contract-performance since the suit is a litigation form to be based on responsibilities of experts, especially doctors, though having factors that are non-contractual as a trait for medical treatment. Further on the concept, when the plaintiff asserts and proves a specific fact from the recent moderation of the burden of proof about medical malpractices, whether the court should find a true bill in medical malpractice actually or not has been discussed.
