This study performs opinion mining of newspaper articles, based on topics extracted by topic modeling. We analyze the attitudes of the news media towards a major issue of 'presidential election', assuming that newspaper partisanship is a kind of opinion. We first extract topics from a large collection of newspaper texts, and examine how the topics are distributed over the entire dataset. The structure and content of each topic are then investigated by means of network analysis. Finally we track down the chronological distribution of the topics in each of the newspapers through time serial analysis. The result reveals that both the liberal newspapers and the conservative newspapers exhibit their own tendency to report in line with their adopted ideology. This confirms that we can count on opinion mining technique based on topics in order to analyze opinion in a reliable fashion.

Although milk, which is a representative western food, has a more than 100-year history in Korea, the preference is controversial. This study examined the milk history of Choseon in 1884~1938. This period was divided into 4 periods regarding the westerner's records and advertisements. Westerners who visited Choseon in 1884~1895 ($1^{st}$ period) recorded the eating habits of Choseon,i.e., no milk consumed, even in insufficient food situation. Among the westerners, medical missionaries began to show or/and recommend condensed milk for sick children. In 1896~1909 ($2^{nd}$ period) newspapers, general shops in Hanseong for westerners showed advertisements of dairy products. In the 1900s, condensed and raw milk were advertised through newspapers. Domestic ranching systems to produce raw milk were established at that time mainly by Japanese. In the 1910s ($3^{rd}$ period), raw milk and condensed milk were advertised in newspapers. Since the mid-1920s ($4^{th}$ period), dairy products were bisected into condensed and powdered (dried) milk. Moreover, many Japanese manufacturers appeared in the advertisement in the 1920s. These results suggest that milk has been recognized as a symbol of an enlightenment food in Korea since the late 1900s, but the old negative wisdom, unfamiliar taste, and high price of milk at that time limited its appeal.

This research analyzes contents of international news in the North Korean newspapers to examine the relationships between foreign policy of the labor party and propaganda of foreign affairs. The results show that international news of the Rodong shinmun and Minjoo Chosun as the ideological apparatus reflects the recent changes of foreign policy of the Kim Jung-Il regime, aiming at the successful control and mobilization of the people. However, the coverage difference between two newspapers has not been found, which means that the press control of the state is routinized. The relationships between political power and the press in North Korea has been discussed from the perspective of international communication.

The purpose of this study is to identify the characteristic of the length of sentence of sports news articles compared with other sections, other newspaper and sports events. In order to achieve this purpose, 4 daily newspapers(Chosun Ilbo, Dong-A Ilbo, Kyunghyang Shinmun and MKsports) were selected as research sources. The length of sentence of collected articles was analyzed by One way ANOVA and Scheffe as post-hoc. The results of these analyses are summarized into three as follows: First, the length of sentence of news articles has significant difference by sections. To put it concretely, the sentences in politics section were the longest, and then economy, editorials comes. The sports section has the shortest sentences. Second, the length of sports articles has significant difference by newspapers. In particular, MK sports which is a sports-oriented newspaper has the shortest in the length of sentence of sports articles than other newspapers such as Chosun, Dong-A and Kyunghyang. Third, the length of sentence of sports articles has significant differences by the sports events. More specifically golf is the longest, and then basketball, soccer and baseball follows.

Background: The publicness concept in healthcare has been built to its social consensus relying on historical context, with the result that the meaning of publicness has a great diversity and heterogeneous nature in Korea. Thus it needs to be addressed to clarify the meaning and boundary of the publicness concept in healthcare, so as to discuss its social implication. Methods: In order to investigate whether or how the publicness concept is used in healthcare, we conducted a text network analysis in 779 news articles from 8 Korean daily newspapers over a recent 5-year period. Results: The publicness concept was closely related to medicine and medical institution, and formed a conceptual network with public health, medicine, welfare, patient, government, Jin-ju city, and health. Keywords relating publicness tended to be similar between four major newspapers; however, the association with Jin-ju city, government, and society was noticeable in Kyunghyang Shinmun and Hankyoreh, and so was patient and service in Dong-A Ilbo. Conclusion: Publicness and medicine was closely associated, and government seemed to remain as a main actor for public interest. Publicness was related with a variety of actors and values, with its expanded boundary. The different contexts of publicness by newspapers might reflect each ideological inclination. The textual importance of publicness was relatively low in part, which suggests that publicness was used in a loose sense or as a routine.

The main purpose of this study was to examine the characteristics of corporate PR practitioners whose opinions were quoted as news sources and of the related articles in the economic section of the nation's three largest newspapers. The results revealed that the PR practitioners were mostly males with the job title of general manager or manager working for large electronics/IT or financing companies in Seoul and near metropolitan areas. In particular, such overwhelming features were more clearly salient in the articles related to conflicts. However, the phenomena seem to have been somewhat eased since 2002 when the newspapers came out with the specialized economic section. Analyzing the articles in terms of the channel of covering news, theme of news, and the existence of any conflict, we found statistically significant differences in the characteristics of PR practitioners. In addition, the comparison between each period before and after the emergence of the specialized economic section also showed statistically significant differences in the characteristics of the PR practitioners in many cases.

This study focuses on the hats in the advertisements of the newspapers from the Greater Korean Empire to the Time of Independence. There were Yeomo(禮帽), Jungsanmoja(中山帽子), Jungjeolmoja(中折帽子), Women's hat, Undongmoja(運動帽子), and Hakdomoja(學徒帽子) from 1897 to the 1900s. The names of the hats were written with Chinese characters as there was no specific name for women's hats. There were a lot of hats in the 1910s; Jungjeolmoja, Jungsanmoja, Hukyeomoja(黑禮帽子), Panama, Doriuchi(鳥打;とり-うち), Maggomo(麥程帽), Ilkyomoja(一交字帽), cheongyeonmo(靑年帽), Jajacheongyeonmo(刺子靑年帽), Hakaaksangmo(學生帽), Undongmo, Laparyunmoja, Banghanmo(防寒帽), Mokchulmo(目出帽), Pungbangi(風防耳), Nambaui, and Pungdongi(風憧耳). Most of the hats were western hats for men. From the 1920s to 1930s, the hats were classified as to the shape and uses as compared to before that period. The hats were advertised in the newspapers such as Jungjeolmoja, Jungsanmoja, Panama, Doriuchimo, Maggomo, Ilkyomoja, cheongyeonmo, Jajacheongyeonmo, Hakaaksangmo, Undongmo, Banghanmo, Mokchulmo(目出帽), Adongmokchulmo(兒童目出帽), Pungdongi, and Pungchasamsangun(風遮三山巾). There is little information about hats from the late 1930s to the time of independence because of the censorship of the press. The hats during that period were almost the same as the before that time. There was a new name of a cap, Jeontumoja(戰鬪帽子) which was for a soldier. The hats in that period were one of the westernized items with shoes before the westernization of the Korean costume under Japanese imperialism. Furthermore, the western hats could be spread by the men who were in the center of the society. On the other hand, women's western hats were not common because women had rarely worn them before that period. They just wore traditional winter caps steadily.

So far, most of Korea's newspapers indexing have been done manually using tesaurus. In recent years, however, the need for automatic indexing system has grown stronger so as for indexers to save time, efforts and money. And some newspapers have started establishing their databases along with introducing electronic newspapers and CTS. This thesis is on establishing and automatic indexing system for the full-text of the Korea Economic Daily's articles, which have been accumulated in its database, KETEL. In my thesis, I suggest methods to create a keyword file, a stopword list, an auxiliary word list and an infected word list by applying linguistic analysis methods to Hangul, taking advantage of the language's morphological peculiarity. Through these studies, I was able to reach four conclusions as follows. First, we can obtain satisfactory keywords by automatic indexing methods that were made through morphological analysis. Second, an indexer can improve the efficiency of indexing work by controlling extracted vocabulary, as syntax analysis and semantic analysis is not complete in Hangul. Third, The keyword file in this system which is made of about 20,000 most-frequently-used newspaper terms can be used in the future in compiling a thesaurus. Finally, the suggested methods to prepare an auxiliary word list and an infected word list can be applicable to designing other automatic systems.

Objectives: The public relies on the news media to understand health risks. To examine the surveillance function of Korean health journalism, this study compared the rank-order of the 10 most frequently diagnosed cancers with that of the 10 cancers most frequently covered by three major Korean newspapers. Methods: News stories published between 1999 and 2010 by the Chosun-Ilbo, Joong-Ang-Ilbo, and Dong-A-Ilbo were examined. Data on cancer incidence were collected using the epidemiological data published by a governmental public health institution. To compare the level of the crude rates and the amount of news coverage, rank-order correlation tests and regression analyses were employed. Results: A reduction in the rank-ordered correlation coefficient was observed despite an increase in the overall number of cancer news stories released. The significance of the correlation disappeared after 2006. The big difference of the rank order between the crude rate and the amount of news coverage was observed in the cancer of breast, uteri, thyroid, and gallbladder/biliary. Finally, the three newspapers did not follow the amount change in stomach, lung, liver, and uterine cervix cancer. The four cancers' rank orders of crude rate were lowering, signifying a reduction of the comparative dangerousness of the four cancers. Conclusions: The news media's customization of news content and the negative bias in journalism are suggested as possible influences on the news media's inaccurate representation of cancer risk.
