In this paper, we introduce a system that summarizes product evaluation through linguistic analysis to effectively utilize explosively increasing product reviews. Our system analyzes polarities of product reviews by product features, based on which customers evaluate each product like 'design' and 'material' for a skirt product category. The system shows to customers a graph as a review summary that represents percentages of positive and negative reviews. We build an opinion word dictionary for each product feature through context based automatic expansion with small seed words, and judge polarity of reviews by product features with the extracted dictionary. In experiment using product reviews from online shopping malls, our system shows average accuracy of 69.8% in extracting judgemental word dictionary and 81.8% in polarity resolution for each sentence.

In this study, we constructed using Random Forest(RF) by selecting the meteorological factors related to the occurrence of frost. As a result, when constructing a classification model for frost occurrence, even if the amount of data set is large, the imbalance in the data set for development of model has been analyzed to have a bad effect on the predictive power of the model. It was found that building a single integrated model by grouping meteorological factors related to frost occurrence by region is more efficient than building each model reflecting high-importance meteorological factors. Based on our results, it is expected that a high-accuracy frost occurrence prediction model will be able to be constructed as further studies meteorological factors for frost prediction.

The purpose f this thesis is to examine the reality of Min Sha-pyeong, which led to life in the end of the Koryo Dynasty.

In order to project changes in climate zones across the Korean Peninsula, the Trewartha's climate classification was applied to the SSP-RCP scenario data with a 1km resolution produced by the National Institute of Agricultural Sciences of the Rural Development Administration. Currently, most of the Korean Peninsula (92.3%) belongs to the temperate climate type (D), whereas only some areas (4.9%), such as Jeju Island, belongs to the subtropical climate type (C). According to SSP-RCP scenarios, the temperature is expected to gradually increase due to the influence of global warming during the 21st century, and the subtropical climate type is expected to expand to 14.1 to 48.6% of the total area of the Korean Peninsula in the far future. On the other hand, the temperate zone, which is currently most dominant on the Korean Peninsula, is expected to shrink by 85.8 to 51.4% in the late 21st century. If carbon dioxide emissions continue at the current rate, the entire Korean Peninsula will likely be dominated by subtropical and temperate regions in the distant future. In particular, the subtropical climate type is expected to dominate most of South Korea in the high-carbon scenario, except for highlands.

In the 21st century, there was a boom of research in the field of Taiwanese historical narrative on Netherland's colonial rule of Taiwan in the 17th century. Such trend expanded to the literature field, and creations were made using the forgotten historical material. Representative works are 《婆 娑之島》 and 《福爾摩沙三族記》, written by Ping Lu and Chen Yao-chang. By analyzing these texts, this study studies what kind of a message the author presents through the literary form, and what his view is on the present and the future. In 《婆娑之島》, Ping Lu presents the fate of Taiwan being in the midst of imperialism for 400 years, and points out the betrayal of imperialism on Taiwan. Ping Lu argues that in order for Taiwan to evade from such situation, the future of Taiwan should be discussed in the global context, outside of the limited perspective of "China/Taiwan". Chen Yao-chang established the Tiwanese identity based on the multiple history narrative, by referencing to the spacial identity instead of the innate kinship. Such establishment of identity gave a breakthrough to the identity politics in Taiwan. Amidst the rapidly changing world politics and economy, it is essential for Taiwan to reestablish the cultural identity for itself for its development. What is more important is that the multiple history narrative maintains openness of history and communicates with the grand narrative to prevent history from being baised.

맨션 <드래곤스레스트>는 이름이 전하는 느낌 그대로 고요함과 웅장함이 가득한 집이다. 거친 듯 아름다운 숲 속 한가운데 자리 잡은 이 저택은 무성한 녹음과 경계를 공유하며 자연의 일부처럼 평온하고도 광활한 느낌을 선사한다. 무려 3만 3200평에 달하는 정원과 420여 평의 주저택으로 구성된 <드래곤스레스트>는 휴양지라는 이름이 더 잘 어울리는 거대한 안식처다.
