This study aimes to describe the forms and characteristics of Myungdang tomb sites in Andongs Area by conducting field trips and analyzing on topographic maps. Most Myundang sites are concentrated around hills, mountains, and tributaries that collectively are located in a northern parts of Nakdong river. The river and the mountain, which the principle of Pungsu, so called Jangpung and Duksu, is applied to, constitute the various forms. They provide the sites with physical settings for Myungdang that can be said to commonly retain such properties as semi-openness, multi-surroundedness, stability, harmony, balance. It can be further argued that those properties of Myungdang sites offer criteria for human settlement and sustainable land development in the current world.

The palaces in South Korea are largely divided into primary palaces (法宮) and secondary palaces (離宮). In the early Joseon period, the primary palace was Gyeongbokgung Palace, and the secondary palace was Changdeokgung Palace. Additionally, there is the concept of imperial palaces (正宮). Gyeongbokgung Palace was the primary palace and the imperial palace. The topography of Gyeongbokgung is based on Mt. Baegak, which is the symbol of royal authority. The location of the palaces was chosen to highlight the king's dignity and authority. The three gates and three courts (三門三朝) were positioned on a straight line based on one axis along the ridge of Mt. Baegak to establish the legitimacy, hierarchy, and unity of the kingship. The secondary palace was built according to the demands of the king and the royal family or the political situation. It was created as a royal living space; thus, creating independent and diverse spaces along multiple axes. The primary palace was chosen to be built on the terrain of Yang, and the secondary palace was chosen to be built on the terrain of Yin; the criteria for laying buildings in the palace areas had to be different. The most important point in the formation of Joseon palaces was that the secret vital energy for the king (王氣) originated from the sacred mountain. Important elements of the palace were the secret vital energy chain of feng shui (風水氣脈) and the forbidden stream (禁川). The secret vital energy chain of feng shui was the gateway to the secret vital energy for the king, and the forbidden stream was a method of preventing the king from leaving the palace grounds. Gyeongbokgung Palace, which is on typical feng shui terrain, faithfully reflects the principles of feng shui. On the other hand, the secondary palace was built on incomplete and irregular feng shui terrain. Feng shui was part of the nature and the geography of the ruling classes in the Joseon Dynasty. By examining their geography, I believe that the perfection of traditional culture inheritance and restoration can be improved.

방재마을 구축 및 운영은 구조적 및 비구조적 재해예방사업을 통하여 지역의 전체적인 방재능력을 향상시키는 것을 기본방향으로 방재마을 구축에 따라 구조적 및 비구조적 컨텐츠가 활용된다. 방재마을 조성에 따른 구조적 및 비구조적 사업은 서로 상호보완적으로 작용되며, 이를 통해 각각의 재해유형과의 연계 및 컨텐츠 제시로 방재력향상을 도모한다. 현재 도시화로 인해 풍수해 발생시 우수유출량 증가로 침수피해 위험이 가중되고 있다. 이에 도시가 돌발성 집중강우에 의한 도시형 침수로부터 주민의 인명과 재산을 보호하기 위해 우수를 신속하게 저류시켜 우수유출량을 줄이는 대책을 수립해야 하며, 풍수해에 대비한 방재마을 구축 컨텐츠 및 운영방안에는 하천정비 및 하도개수, 하수도 정비 및 확충, 홍수조절, 저류지설치, 우수저류 및 우수침투시설 설치 등이 있다. 방재마을 운영 및 활성화를 위한 비구조적 사업은 재해예방을 위한 주민 기업 단체자구노력, 풍수해 예방주민활동, 침수피해 주민예방 활동, 지역자율방재단 운영, 주민주도의 추진체계 구축 등이 있다. 성공적인 방재마을만들기를 위해서는 주민주도의 추진체계를 확립하도록 하는 것이 무엇보다 중요하며, 방재마을에 있어 주민참여가 방재도시만들기와 밀착되어 전개될 때 방재마을의 운영 및 관리 효과가 향상된다. 따라서 구조적 운영방안과 함께 주민추진체계를 중심으로 한 방재마을 구축 및 운영을 통해 방재마을 활성화를 도모할 수 있을 것으로 사료된다.

Natural catastrophe is defined as all damages caused by natural phenomenon such as typhoon, flood, inundation, windstorm, tidal wave, tremendous snowfall, drought,earthquake and to on It is classified at a huge hazard because of the large severity ofdamage In Korea, Fire Insurance policy includet the coverage clauses and rates of naturalcatastrophe like'Flood , Inundation Coverage Clause'and'Earthquake Coverage Clause'These clauses and rates do not reflect accurate risk of flood, inundation and earthauakein Korea. because those are tariff from other countries Hence, we determine the claimsize distributions and the rates for typhoon coverage and flood-inundation coverage byusing statistical methods which have not been used so far in Korean non-life insurance,and calculate appropriate premium for policyholder's interest

This study aims at designing standard metadata that can be incorporated for advanced utilization of damage prediction maps, and thereby constructing the standard meta-information management prototype system on the basis of the proposed design. Based on the ISO/TC 211 19115 international standard, which is considered as the most widely used standard (as per the results of a domestic and foreign metadata standard survey), the designing process for the standard metadata was established and the metadata was categorized into nine classes. Additionally, based on the output of the standard metadata design process, a standard meta-information management prototype system, capable of checking and downloading meta-property information, was constructed using the JAVASCRIPT language. By incorporating the obtained results, it is possible to maintain the quality of the constructed damage prediction map by establishing a standardized damage prediction map database. Furthermore, disaster response can be actuated through the provision and management of data for effective operation of the proposed damage prediction system.

인근의 저수지의 높이를 높여 도심구간의 하천 유량이 얼마나 증가되는지 확인하기 위해 지천 상류에 위치한 유역면적 65.8 $km^2$인 청양의 도심하천 위치에서 1966년부터 2007년까지 유량을 모의하고, 목표유량을 0.31 $m^3/s$로 설정하여 상류에 위치한 유역면적 17.5 $km^2$, 저수량 512만 $m^3$인 칠갑지의 숭상으로 방류량 증가에 따른 하천유량의 증가효과를 분석한 결과는 다음과 같다. 첫째, 칠갑지 없는 경우 청양 도심하천 유황은 연평균하여 풍수량 1.49 $m^3/s$, 평수량 0.44 $m^3/s$, 저수량 0.20 $m^3/s$, 갈수량 0.16 $m^3/s$로 분석되었으며, 목표유량 0.31 $m^3/s$보다 0.15 $m^3/s$ 적게 나타났다. 둘째, 칠갑지로부터 682 ha의 논에 관개용수를 공급하는 경우 용수공급량/유역면적은 453.9 mm, 단위유역 용수공급량/강우량 비율은 39.1 %, 용수공급량/유입량 비율은 96.5 %, 용수공급량/저수량 비율은 163.7 %, 유입량/저수량 비율은 226.5 %였으며, 이수안전도는 일단위 52.4 %, 일단위 96.9 %였다. 셋째, 현재 규모의 칠갑지 운영을 고려한 청양 도심하천의 유황은 연평균하여 풍수량 1.40 $m^3/s$, 평수량 0.42 $m^3/s$, 저수량 0.19 $m^3/s$, 갈수량 0.16 $m^3/s$로 분석되어 갈수량은 칠갑지가 없는 경우와 같게 나타났다. 넷째, 칠갑지 규모를 5 m 더 높인 경우 청양 도심하천의 유황은 풍수량 1.40 $m^3/s$, 평수량 0.43 $m^3/s$, 저수량 0.24 $m^3/s$, 갈수량 0.20 $m^3/s$로 분석되어, 목표유량 0.31 $m^3/s$보다 0.11 $m^3/s$ 적게 나타났다. 다섯째, 칠갑지 규모를 10 m 더 높인 경우 청양 도심하천의 유황은 풍수량 1.42 $m^3/s$, 평수량 0.47 $m^3/s$, 저수량 0.27 $m^3/s$, 갈수량 0.23 $m^3/s$로 분석되어, 목표유량 0.31 $m^3/s$보다 0.08 $m^3/s$ 적게 나타났다. 여섯째, 칠갑지 규모를 15 m 더 높인 경우 청양 도심하천의 유황은 풍수량 1.43 $m^3/s$, 평수량 0.47 $m^3/s$, 저수량 0.27 $m^3/s$, 갈수량 0.23 $m^3/s$로 분석되어, 10 m 높인 경우와 같게 나타났다. 결과적으로 칠갑지 규모를 높여 하천유량의 증가효과는 한계가 있는 것으로 밝혀졌으며 최적규모 결정을 위해서는 추가 연구가 필요하며, 부족유량을 충족하기 위해서는 다른 방법이 추가로 필요한 것으로 나타났다.

In this study, Neural Networks models were used to forecast daily streamflow at Jindong station of the Nakdong River basin. Neural Networks models consist of CASE 1(5-5-1) and CASE 2(5-5-5-1). The criteria which separates two models is the number of hidden layers. Each model has Fletcher-Reeves Conjugate Gradient BackPropagation(FR-CGBP) and Scaled Conjugate Gradient BackPropagation(SCGBP) algorithms, which are better than original BackPropagation(BP) in convergence of global error and training tolerance. The data which are available for model training and validation were composed of wet, average, dry, wet+average, wet+dry, average+dry and wet+average+dry year respectively. During model training, the optimal connection weights and biases were determined using each data set and the daily streamflow was calculated at the same time. Except for wet+dry year, the results of training were good conditions by statistical analysis of forecast errors. And, model validation was carried out using the connection weights and biases which were calculated from model training. The results of validation were satisfactory like those of training. Daily streamflow forecasting using Neural Networks models were compared with those forecasted by Multiple Regression Analysis Mode(MRAM). Neural Networks models were displayed slightly better results than MRAM in this study. Thus, Neural Networks models have much advantage to provide a more sysmatic approach, reduce model parameters, and shorten the time spent in the model development.
