신석기시대 이른 시기에 한반도 중동부지역에 분포하고 있었던 평저토기는 고성 문암리유적의 발굴을 통해 기존의 연구와는 다른 변천을 하였음을 알게 되었다. 그러나 압날문토기 자체의 변천과 융기문토기의 등장 및 양자의 관계 등에 많은 과제를 던지고 있기도 하다. 한편, 고성 문암리유적의 토기를 비롯 석기, 토제품, 장신구 등 다양한 물질문화에는 두만강 하류지역과 남부지역과의 영향관계가 잘 반영되어 있어, 양지역과의 관련성을 엿볼 수 있었다. 특히, 중동부지역과 두만강 하류지역간의 영향관계보다 남부지역과 중동부지역간의 영향이 보다 광범위한 기종에, 그리고 공유의 차원이 제작기법과 같은 부분에까지 미치고 있었음을 알았다. 이 사실은, 남부지역에 일시적으로 중동부지역 사람의 이동 내지는 분포범위의 확대를 통한 직접적인 영향이 있었을 가능성을 시사해 주는 것이라고 생각된다.

While social networks have become very popular and powerful way of connecting people and sharing new information, they also effectively spread wrong or biased information to the public. We examine the so-called "Shandong peninsular rumor" that claims Chinese government is responsible for the increased air pollution in South Korea and Japan, by moving pollution-causing industries near Beijing to the Shandong peninsular which is close to South Korea. We demonstrate that the amounts of $NO_x$ and $SO_2$ emissions inferred by space-borne monitoring and regional air quality models show clear declining trends in past several years. We do not have any evidences to support the relation of Shandong peninsular emissions change to South Korean air quality.

Analysis has been made on the wind wave characteristics in terms of significant wave height ($H_s$) near the Korean marginal seas in the 2006 - 2007 year using the third generation wave model, WAVEWATCH - III model. In order to evaluate its performance, its results were compared with the observed data using KMA ocean buoy. The two year average RMSE between modeled and observed Hs shows reasonably small value of about 0.37 m. The accuracy of predicted values in the year 2007 is increased mainly due to finer model grid size and better accurate wind field. The model used in this study predicts very well the characteristics ($H_s$) of wind waves near the Korean Peninsular. Simulated monthly wind waves show the evident seasonal variations due to Typhoons in summer season. When Typhoons approach to Korean Peninsular, the accuracy of wind waves predictions is lower than that of annual mean value.

2000년부터 2004년까지 태국 (Thailand) 중부지역의 4개 수역인 Eastern, Chao Phraya, Peninsular, Maeklong 수계를 흐르는 하천에서 어류상 조사를 실시하였다. 160개 조사지점에 대하여 어류상조사를 실시한 결과 총 28과 124종이 확인되었다. Eastern과 Peninsular수역에서 각각 33종, 42종이 출현하였고 Chao Phraya와 Maeklong수역에서 52종과 91종이 확인되었다 4개 수역에서 모두 출현한 종은 Brachydanio albolineatus, Rasbora paviei, Systomus binotatus, Homaloptera smithi, Monopterus albus, Macrognathus circumcintus, Channa gaucha 등 7종이었다.

Efficiency and limitations of HAZUS-MH, a GIS based systematic and informative system developed by FEMA and NIBS for natural hazard loss estimations, are discussed by means of a pilot study in the Korean Peninsular. Gyeongsang-do has been selected for the test after careful reviews of previous studies including historical and modern seismicity in the peninsular. A ShakeMap for the selected scenario earthquake with magnitude 6.7 in Gyeongju area is prepared. Then, any losses due to the scenario event have been estimated using HAZUS. Results of the pilot test show that the study area may experience significant physical, economic and social damages. Detailed study in the future will provide efficient and crucial information to the decision makers and emergency agents to mitigate any disaster posed by natural hazards.

Data for occurrence of hail over Korean Peninsula for the period 1961-2005 are obtained from the Korea Meteorological Administration (KMA). According to the average occurrences during each season in Korea Peninsular, hail days are almost distributed uniformly in the spring, fall and winter, except the summer and have averages of 5 days for each season. Analysis of regional occurrence of hail shows that inland of Korea Peninsular is vulnerable to hail in the spring and summer and the islands of Ullung, Baegryeong and Cheju and the coastal regions vulnerable in the fall and winter. It can be postulated that these seasonal patterns of hail is affected by the Monsoon effect.

This study introduces a method to generate artificial earthquakes in Korean Peninsular using historical earthquake catalogues and point source model. For this purpose, three earthquake catalogues compiled by different researchers are compared to each other. And epicenters and magnitudes of future earthquakes are generated based on those catalogues. In generating ground motion accelertation, point source model proposed by Boore and Atkinson was adopted. Parameters of the model for South-Eastern part of Korean Peninsular was proposed by Noh and kn. From the epicenters, magnitudes, and ground motion models, possible earthquakes for 50,000 years are generated. Using these generated earthquakes ground accelrations and uniform hazard response spectra (UHRS) having 2%, 5%, and 10% exceedance probability in 50 years are proposed.

The construction of the Great Korea Canal(GKC) In the Korean peninsular requires consideration from a aspect of vision of the national land development. GKC will bring enormous benefits to the Korean economy. First, effect of the equitable regional development. Second, reduction In freight transport costs and contribution of innovation in physical distribution. Finally, creation of large numbers of new jobs and development of Tourism & Leisure Industry and its related industry. Lets view the construction and finance supply.

We develop a model to predict typhoons in Korea. We collect data for typhoons and classify those depending on the severity level. Following a Bayesian approach, we develop a model that explains the relationship between different levels of typhoons. Through the analysis of the model, we can predict the rate of typhoons, the probability of approaching Korean peninsular, and the probability of striking Korean peninsular. We show that the uncertainty for the occurrence of various types of typhoons reduces dramatically by adaptively updating model parameters as we acquire data.

In this paper, we have proposed a method for quantization of the stratification strength in the sea water and analysing the distributions of the maximum stratification depths calculated by the method at the seas near the Korean peninsular. For calculating the stratification strength, modified and applied the potential energy anomaly formular which was suggested by Simpson in 1977. The data had been collected by NFRDI from 1971 to 2008 were used to determine the maximum vertical density gradient depth and the relative potential energy anomaly at that depth. In the East Sea, the stratification depth has become deepened about 20m in February and April since 1971. In Yellow-South Sea, the maximum density gradient depth has been deepened about 10m only in December during the same period and the difference of the stratification depth between summer and winter has been enlarged. These trends of variation of stratification strength and depth near the Korean peninsular should be investigated more carefully and continuously. And the results of these studies could be adopted for the more efficient operation of underwater weapon and detection systems.
