  • In this paper, we propose a new method utilizing only raw corpus without additional human effort for disambiguation of target word selection in English-Korean machine translation. We use two data-driven techniques; one is the Latent Semantic Analysis(LSA) and the other the Probabilistic Latent Semantic Analysis(PLSA). These two techniques can represent complex semantic structures in given contexts like text passages. We construct linguistic semantic knowledge by using the two techniques and use the knowledge for target word selection in English-Korean machine translation. For target word selection, we utilize a grammatical relationship stored in a dictionary. We use k- nearest neighbor learning algorithm for the resolution of data sparseness Problem in target word selection and estimate the distance between instances based on these models. In experiments, we use TREC data of AP news for construction of latent semantic space and Wail Street Journal corpus for evaluation of target word selection. Through the Latent Semantic Analysis methods, the accuracy of target word selection has improved over 10% and PLSA has showed better accuracy than LSA method. finally we have showed the relatedness between the accuracy and two important factors ; one is dimensionality of latent space and k value of k-NT learning by using correlation calculation.

  • The study aimed to perform the qualitative analysis of food and nutrition informations offered in TV program by monitoring newscastings, health-related programs giving food and nutrition information, dramas for family, education programs for children, and information programs for elderly in major TV broadcasting station(KBS, MBC, SBS, EBS). In this study, statistical analysis were done for numbers of information items related to health or food and nutrition informations. Duration of program the main, subject, sources, evaluation criteria of the contents. Results of qualitative monitoring for TV program are as follows. For health-related informations major propotions of subjects for the newscastings were about diseases. Those for health information programs were about foods. Those for children-education programs were about groceries. Those for seniors’ information programs were about eating habits. The analysis of food and nutrition information sources for most of programs were interviews with specialist and normal person, and on-the-spot-investingations. For food and nutrition informations those were evaluated as inappropriate, the propotion of news was increased to 72.2% in 2003 from 49.3% in 2002. For health information programs, it was increased to 67.7% in 2003 from 54.0% in 2002. But, in drama the propotion of inappropriate scenes were decreased to 16.2% in 2003 from 63.2% in 2002. In children-education programs, it was 40.0%. In seniors’ information programs, it was 17.9% in 2002. The propotion of cases that the quantity of foods is inappropriate in the food scene of serial drama, decreased to 15.8% in 2003 from 28.6% in 2002. The rate of drinking scenes increased to 11.5% from 10.7%. The rate of smoking scenes decreased to 0.2% from 1.6% due to the broadcasting self-regulation of smoking scenes in dramas. In the newscatings and information programs, reasons of being evaluated as inappropriate was that they didn’t have any practical suggestions and proper intakes. There were also insufficient explanation for technical terminology, different comparison standard of nutritive value, and exaggeration for physiological effect of food. The drama contained a lot of unnecessary scenes of alcohol drinking, coffee drinking, midnight meal, and had more quantity of foods than the quantity needed for persons to the scene. As the result of this study, the rate of food and nutrition information were high, but the rate of information which was evaluate as appropriate was not sufficient. There are need to improve contents of information and to moniter the contents for consumer.

  • The satellite-based red tide detection algorithms have been developed for specific occurrence waters and red tide species. However, it is essential to study the whole occurrence waters and various red tide species for quick and accurate surveillance of red tide around the Korean coastal waters. In thisstudy, the comprehensive analysesinvolve the spectral features of red tide areas and the suitability of the satellite-based red tide detection algorithms used with GOCI in the Korean coastal waters. As a result, the spectral characteristics were changed according to the chlorophyll content of red tide species and the turbidity of the waters where the red tide appeared. In addition, the previous red tide detection algorithm is applied to GOCI, and it is found that there is a limitation to the red tide area extraction as the existing threshold value. To overcome these limitations, red tide species were divided into two groups according to the difference of chlorophyll content and a system for red tide surveillance wassuggested. It is possible to distinguish between red tide and non-red tide area through five steps. As a result of applying to GOCI, the red tide was appropriately extracted from the previous algorithm based on red tide breaking news. If such a red tide surveillance system is used, it will be possible to efficiently monitor red tide by quick and accurate surveillance of the whole occurrence waters around the Korean and various red tide species.

  • With the introduction and expansion of 'maker movement', maker culture captured attention and saw itself as an emerging culture. This study aims to analyze published books, policy report, columns and news articles related to maker culture through the perspective of critical discourse analysis. Maker movement led by the government gives meaning to the maker culture as the force of 'creative economy' that can overcome the economic crisis. Following this meaning making, one-man digital fabrication start-ups have been actively promoted by government policies. In the case of Seoul, it criticizes government led maker movement that only focuses on economy and institutionalizes maker movement by focusing on the maker culture's aspect as 'digital social innovation' that can resolve social problems. In the world of art, it tries to rediscover the value craft, that is, 'creative craftsman'. Moreover, resistance movement that tries to fight against dominant technology structure through constructing 'critical making' was also spotted. Nonetheless, it is rather untimely to definitely find dominant discourse's power effect in reality and sign of rupture in dominant structure as the result of resisting discourse's struggle. Thus, maker movement is the field of struggle where an ongoing clash can be found: between discourse strategy that tries to make maker culture a social or economic asset by combining with dominant power structure, and alternating or resisting practice of signification that focuses on its cultural techno-political potential.

  • This study aims to analyze the social and legal status of Internet personal broadcasting in Korea and propose the direction of personal broadcasting regulation based on overseas regulatory laws and the media characteristics of Internet broadcasting. The influence of Internet personal broadcasting has increasing, and social and legal problems such as pornography and fake news have also growing. In the absence of legal regulations on personal broadcasting on the Internet, academia is also discussing relevant legislation and policies at a general level of analysis. In addition, the current study argues that new legislative research is needed to respond to the rapidly changing media environment and to cope with the newly introduced Internet broadcasting content and platforms. The findings suggest that freedom of expression is a significant value, yet obscene materials for minors should be thoroughly regulated, and that internet personal broadcasting should be regulated to the minimum extent through self-regulation guidelines through cooperation between councils and related agencies or businesses. The significance of the current study indicates that it proposed the practical and concrete laws for the improvement of the quality of Internet personal broadcasting content, the establishment of new broadcasting policies for fair and diverse content development, and the efficient and fair regulation of personal broadcasting content.

  • Developing a high-performance Semantic Role Labeling (SRL) system for a domain requires manually annotated training data of large size in the same domain. However, such SRL training data of sufficient size is available only for a few domains. Performances of Korean SRL are degraded by almost 15% or more, when it is directly applied to another domain with relatively small training data. This paper proposes two techniques to minimize performance degradation in the domain transfer. First, a domain adaptation algorithm for Korean SRL is proposed which is based on the prior model that is one of domain adaptation paradigms. Secondly, we proposed to use simplified features related to morphological and syntactic tags, when using small-sized target domain data to suppress the problem of data sparseness. Other domain adaptation techniques were experimentally compared to our techniques in this paper, where news and Wikipedia were used as the sources and target domains, respectively. It was observed that the highest performance is achieved when our two techniques were applied together. In our system's performance, F1 score of 64.3% was considered to be 2.4~3.1% higher than the methods from other research.

  • The development of online content is changing the value of society very diversely and rapidly. In particular, the non-face-to-face e-sports industry is growing significantly in the current situation where the COVID-19 Pandemic has not been completely overcome. The use of NFT in the eSports industry is receiving positive reviews as a field with high potential for future growth that protects digital assets of eSports users, but at the same time, it is raising concerns that cash transactions of digital items could encourage gambling. In this study, the characteristics of the recent eSports industry and NFT were identified and classified through case studies using literature, official sites, and online news articles. Through various cases of eSports and NFT, we discussed the potential for future growth and activation plan of the NFT industry of eSports. The result is as follows. First, it is necessary to use NFT using IP of eSports event itself. Second, it is necessary to combine the functional role of the item with NFT to provide features that users can utilize. Third, it is necessary to provide users with opportunities to engage in economic activities using eSports and NFT. Finally, it is necessary to use NFT to strengthen the digital asset protection of eSports users. Through this study, it is expected to be used as a basis for further discussions on the NFT industry of e-sports and as a material for securing competitiveness.

  • In the year 2013, Warren Buffett was named one of the most influential people of the year by TIME magazine. When people are exposed to such news, they show strong interest in who the influential people are and how those people became so successful. Likewise, people show strong attachment to other prominent figures as well. This social phenomenon indicates that people perceive well-known persona like business leaders, TV stars or sports stars etc. as human brands of intangible assets. As the role of these human brands is becoming more important, people tend to develop stronger attachment toward them. Another notable modern social phenomenon is people's pursuit of life-satisfaction and social well-being. People desire to increase their quality of life by having quality time with family and friends, and also by building attachment towards celebrities, sports stars, and so on. The main objective of this study is to examine how attachment toward human brands affects quality of life. While existing studies on human brands examined antecedents of attachment, e.g., some needs fulfillment such as A-R-C needs (autonomy, relatedness and competence needs) fulfillment, this study focuses on the outcome variables of attachment, e.g., how attachment toward human brands affects stress relief and life satisfaction through self-efficacy. Based on previous research, we divided human brands into two types: heroes and celebrities. Heroes are defined as people who have considerable and lasting importance on both societal and individual levels, and celebrities are defined as people who are well-known but have little or no short-term impact on society and individual levels. This study focuses on how attachment toward each type of human brands, celebrities and heroes, affects the quality of life or well-being. This study focuses on three important outcome variables; stress relief, life satisfaction, and self-efficacy, (three variables) which have been recently gaining importance, especially in the domain of positive psychology. Major findings from the present study show that although celebrities draw attachment from people by providing fun and entertainment or providing stress relief, they have weak influences on the wellbeing or efficacy of individuals at a deeper level. In contrast, attachment toward heroes helps people live better by providing meaning and positively influencing life satisfaction through self-efficacy (Frankl 1997). These results are consistent with the main tenet of 'positive psychology' which seeks "to find and nurture genius and talent and to make normal life more fulfilling" (Seligman and Csikszentmihalyi 2000). Considering the fact that certain celebrities are perceived as heroes to some, we can conclude that celebrities can become heroes if they provide meaning and value to the lives of people. This study contributes to the research stream of human brands since the most current leading research (e.g., Thomson 2006) indicated the need to look at the resulting effect of attachment on life satisfaction through self-efficacy. Another important contribution is that we empirically documented the different effects of celebrities and heroes. As expected, this study shows that heroes more deeply influence the lives of individuals in the long term while celebrities do so rather shallowly in the short term. The issues of the influence of heroes on the individuals' lives need to be further investigated in relation with the perspective of positive psychology.

  • Purpose As breast cancer patients continue to increase every year, cases of BSGI are on the rise with a heavier reliance on it. However, BSGI protocol in hospitals was not studied enough despite it was covered by hospital's condition and recommendation of manufacturers. The objective of the study was an examination of methods to be applicable to BSGI protocols, putting the self-development phantom to use in quality assessment of the images. Materials and Methods Dilon 6800 (Dilon Technologies Inc, Newport News, USA) was used in the study and five different sizes of sphere were distinctively produced in the phantom. The study used $^{99m}TcO_4$. The cases were classified in to three categories that background radioactivity to region of interest as ratio of 2: 4: 8, They were acquired images for 5, 7, 10mins. The acquired image was set region of interest according to the size of sphere, and We analyzed quantitative and qualitative analysis. The acquired data statistically analyzed with SPSS ver.18.0. Results As the result of quantitative and qualitative analysis, count rate of each sphere in accordance with difference of injection dose showed that higher count rate as injection dose and sphere size increased (P<0.005). Count rate of each sphere in accordance with difference of acquisition time showed that higher count rate as acquisition time and sphere size increased (P<0.005). Contrast noise ratio of each sphere in accordance with difference of injection dose showed that higher contrast noise ratio as injection dose increased. Particularly, Contrast noise ratio of eight times ratio images was the highest among. Contrast noise ratio of each sphere in accordance with difference of acquisition time showed that higher contrast noise ratio as acquisition time increased. And, Contrast noise ratio of seven minute image was the highest among (P<0.005). Conclusion There was significant change of Contrast noise ratio through quantitative and qualitative analysis. Moreover, We found usefulness of phantom. If Institutions identified image through the phantom study and they made BSGI protocol, We expected to help the improvement of diagnostic value of the images.
