This text attempts two types of critical analysis. First is to explore Luxun's critical research attitude toward classical Chinese texts, studying how Luxun critically examines 'liyue (ceremony- music)'. With the way the 'madman' in 《A Madman's Diary》 handles China's old text as a hint, the attitude with which Luxun critically examines the editing and passing down of classical Chinese philology was studied. Luxun pays attention to the situation in which when classical literature is passed down and transmitted throughout history, the context of events are concealed and text is blockaded while text is edited and restructured. Also, Luxun critically examines how the ancient culture of 'liyue' operates on the constitution of Chinese culture, society, and politics, in addition to the process of passing down of texts, as well as how it has effect even in the present day. Classics are closely intertwined not only with issues of the past but with the conventions, moral emotions, and government of today. Second, based on Luxun's examination of 'liyue', the <sheng-wu-ai-le-lun> of the 《Jikangji》 which Luxun sympathized with all his life is criticized. This text, stating that 'There is no sadness or happiness in sound', deeply ponders upon the issue of 'liyue' essential to the logic of Chinese cultural composition, and deviates from the Confucian thoughts centered around social integrity and inspiration. Further, it stresses the autonomy of affective subject, and the process of deliberation by an entity toward harmony and commonness. By the work of examining Jikang through Luxun and Luxun through Jikang, the uncompleted work of classical criticism by Luxun is restructured, and the possibility of classical Chinese texts to relate to today's life is examined.

The purpose of this study is to explore the meaning of happiness and unhappiness in Korean society through text mining analysis. Similar words with keywords(happiness/unhappiness) from online news portal are extracted using Word2Vec and TF-IDF method. We also use the K-LIWC dictionary to perform the sentiment analysis of words associated with happiness and unhappiness. In TF-IDF analysis, happiness and unhappiness are highly related to social factors and social issues of the year. In Word2Vec analysis, 'Hope' has been similar with happiness for six years. In K-LIWC analysis, 'money/financial issues', 'school', 'communication' is highly related with happiness and unhappiness. In addition, 'physical condition and symptom' is highly related to unhappiness. Implications, limitations, and suggestions for future research are also discussed.

This study aims to infer the gene-protein 'brings_about' chains of pancreatic cancer which were referred to in the pancreatic cancer related researches by constructing the gene-protein interaction network of pancreatic cancer. The chains can help us uncover publicly unknown knowledge that would develop as empirical studies for investigating the cause of pancreatic cancer. In this study, we applied a novel approach that grafts text mining and the main path analysis into Swanson's ABC model for expanding intermediate concepts to multi-levels and extracting the most significant path. We carried out text mining analysis on the full texts of the pancreatic cancer research papers published during the last ten-year period and extracted the gene-protein entities and relations. The 'brings_about' network was established with bio relations represented by bio verbs. We also applied main path analysis to the network. We found the main direct 'brings_about' path of pancreatic cancer which includes 14 nodes and 13 arcs. 9 arcs were confirmed as the actual relations emerged on the related researches while the other 4 arcs were arisen in the network transformation process for main path analysis. We believe that our approach to combining text mining analysis with main path analysis can be a useful tool for inferring undiscovered knowledge in the situation where either a starting or an ending point is unknown.

The stock price reflects people's psychology, and factors affecting the entire stock market include economic growth rate, economic rate, interest rate, trade balance, exchange rate, and currency. The domestic stock market is heavily influenced by the stock index of the United States and neighboring countries on the previous day, and the representative stock indexes are the Dow index, NASDAQ, and S & P500. Recently, research on stock price analysis using stock news has been actively conducted, and research is underway to predict the future based on past time series data through artificial intelligence-based analysis. However, even if the stock market is hit for a short period of time by the forecasting system, the market will no longer move according to the short-term strategy, and it will have to change anew. Therefore, this model monitored Samsung Electronics' stock data and news information through text mining, and presented a predictable model by showing the analyzed results.
