One of the problems with current youth generations is increasing rate of violence and suicide in their school lives, and this study aims at the design of a sentiment analysis system to prevent suicide by uising big data process. The main issues of the design are economical implementation, easy and fast processing for the users, so, the open source Hadoop system with MapReduce algorithm is used on the HDFS(Hadoop Distributed File System) for the experimentation. This study uses word count method to do the sentiment analysis with informal data on some sns communications concerning a kinds of violent words, in terms of text mining to avoid some expensive and complex statistical analysis methods.

As World Wide Web is more popularized nowadays, the environment is flooded with the information through the web pages. However, despite such convenience of web, it is also creating many problems due to uncontrolled flood of information. The pornographic, violent and other harmful information freely available to the youth, who must be protected by the society, or other users who lack the power of judgment or self-control is creating serious social problems. To resolve those harmful words, various methods proposed and studied. This paper proposes and implements the protecting system that it protects internet youth user from harmful contents. To classify effective harmful/harmless contents, this system uses two step classification systems that is harmful word filtering and SVM learning based filtering.

This paper deals with the nature and function of intensification in Korean in a wider scope of intensification which was not paid proper attention including intensification in the initial position as well as middle position. Unobserved new areas of intensification in the initial position are paid more attention like sound split of polysemy e.g. (s'eda), (kyongk'i) by means of intensification and north Korean application of intensification on (wonsu) and intensification of borrowed English. The recent phenomenon of ‘gwua’ intensification is experimented on two groups of people, young students and old people beyond 65 years old by means of sociolinguistic analysis. The result shows that its intensification is a form of student violent power and a mark of extreme solidarity among activist students. Thirty three university students(male 16, female 17) are asked to explained to write the meanings(feelings or when to use, etc.) of the words which have normal form and intensified forms. The results show intensification attaches the meaning of ‘emphasis,’ to bring the extremely polarized emotion: samll to the smallest, exact to the perfect exactness, bad to the worst feeling. Four words are being split to express different meaning with the word intensified. In conclusion, the nature of so called saisiot(t) e.g. intensification is voiceless tensed pause and its functions are the polarization of the original meaning of the word, sound split of polysemy and attachment of social values by intensification.

This paper deals with the nature and function of intensification in Korean in a wider scope of context which was not paid proper attention. Unobserved new areas of intensification are paid more attention like sound split of polysemy e.g. [s'eda], [kyongk'i] by n of intensification and north Korean application of intensification on [wonsu] and intensification of borrowed English. The recent phenomenon of 'gwua' intensification is experimented on two groups of people, young students and old people beyond 65 years old by means of sociolinguistic analysis. The result shows that its intensification is a form of student violent power and a mark of extreme solidarity among activist students. In conclusion, the nature of so called saisiot[t] e.g. intensification is voiceless tensed pause and its functions are the polarization of the original meaning of the word, sound split of polysemy and attachment of social values by intensification.

The purpose of this study is to examine the realities of the chaotic use of terms, 'tattoo' and 'moonsin', through the empirical field researches. This paper will research the differences in the origins and the etymological meanings of 'tattoo' and 'moonsin' through examining related literatures. Clarifying the term definitions on 'tatto' and 'moonsin', this research is to help fashion consumers to use these terms discretely. In order to figure out consumers' perceptive attitude, this study has performed the questionnaire inquiry and has reached the result by analyzing the level of frequency of using the two terms. 1. The result of the term-preference inquiry tells that consumers prefer 'tattoo' to 'moosin'. However, the inquiry shows considerable number of them use the two terms indiscretely. 2. The study on the perceptions from the two terms shows: the term 'tattoo' is often related to positive images-fashionable, charming, and sexy, and the term 'moonsin' to negative ones-violent, anti-social, and demonic. 3. Both 'tattoo' and 'moonsin' shares the similarity in terms of engraving patterns on skin and coloring them. 4. 'Tattoo' is originally derived from the Polynesian word 'tatau', which means 'artistic'. 'Tatau' is a kind of ethnic art practiced on Polynesian people's skin. The design patterns and practicing techniques are very similar to those on the Polynesian earthware called 'Lapita'.

Due to the paradigm of open science and advanced digital information technology, data sharing and re-use have been actively conducted and considered data-intensive in a wide variety of disciplines. This study aims to investigate the intellectual structure portrayed by the research products re-using the data sets from ICPSR. For the purpose of this study, a total of 570 research products published in 2017 from the ICPSR site were collected and analyzed in two folds. First, the authors and publications of those research products were analyzed in order to show the trends of research using ICPSR data. Authors tend to be affiliated with university or research institute in the United States. The subject areas of journals are recognized into Social Sciences, Health, and Psychology. In addition, a network with clustering analysis was conducted with using co-word occurrence from the titles of the research products. The results show that there are 12 clusters, mental health, tabocco effect, disorder in school, childhood, and adolescence, sexual risk, child injuries, physical activity, violent behavior, survey, family role, women, problem behavior, gender differences in research areas. The structure portrayed by ICPSR data re-uses demonstrates that substantial number of studies in Medicine have been conducted with a perspective of social sciences.
