This study intended to analyze growth condition of each object by protected tree's ground for 45 places registered to Pyeongtaek protected tree list in locational characteristics, conduct exchange analysis for impediment extent rate in crown area and tree type to the result and suggest the measures to manage artificial impediment which is an effect on protected tree condition. In this study, the tree whose area of impediment for crown area is less than 21% is tree condition of grade 1~2, less than 21~50% is grade 2~3 and more than 50% is grade 3~5. The more impediment is, the more inconvenience causes on growth and development. So, it verified that the area rate must maintain less than 21% for the root system management of protected tree. For the standard of managing artificial impediment which is an effect on the tree condition of protected trees, the below matters intend to be suggested. The first, the impediment in crown area should be less than 21%. But, if there is not artificial impediment out of crown area, the rate of impediment area is considered to increase somewhat. The second, growth space of protected tree should be maintained by crown area at least and impediment should be established out of the crown area. The third, during the national project and land development, surroundings of protected tree must be applied as park, resting place, etc. and the establishment area of impediment (artificial impediment and natural impediment) in crown area must be limited. The forth, publicity for regional people (especially, land owner) is necessary for the protection of natural inheritance and the value of dependence on local government and village which are the subject of management must be announced widely through the internet media, etc, so its importance must be recognized. The fifth, the matters related to protected tree management must be able to limit artificial damage which is for surroundings of protected tree through the mutual connection among the local governments; construction, civil engineering, architecture, water and sewage, agriculture and forest and others. Also, following studies on the effects of kinds, thickness, etc. of impediment around the protected tree on trees should be continued.

Military style is not limited to a single period but represents various image communications related to items, synthetic images and different periodical culture backgrounds. The purpose of this study is to define the communicational function of the military style beginning from the 1st world war up to the modern days, and furthermore explain the characteristics and contents of military styles in different periods by studying the nowadays various symbols of the military style in denotative and connotative aspects. The research method is documentary studies through the literature and academic paper, and examined masters' and doctors' thesis, domestic and overseas books and fashion magazines, photographs and materials collected from the internet. As a result, first, the military style is a significant fashion code in understanding modern fashion by serving as a strong communication function representing people’s ritual through various image items called the 'military look'. Second, the meaning of the image communication through military look changed throughout the different periods. During the 1st and 2nd World war the military look supported Fascism by serving as a media representing extreme patriotism and at the same time social images like functionalism, women liberation, regulation and saving. During the cold war period it was used by young progressives like hippies and punks to send an opposing message towards war and commercialism. Since then up to the 80s it was a medium representing the ‘new role of women’, who possess same social rights and power as the men. However in the 90s the military style had to go through a paradigm transition period. Since this period it got affected by the post modernism and designers, consumers alike adopted military style to create unique beauty It can also be said that it began to be used as a pure fashion code representing intertextuality. It was rather expressed as a metonymy than a metaphor and combined with elegance and feminine factor, which contrasts to the original military concept, it now represents totally new hybrids such as difference, dissemination and varieties.

This study investigated the effects of the 'Meeting With Scientists' program on children's stereotypical images of scientist. To do those, 36 children of a fifth grade class participated in the program for one month. The program consisted of two main activities:(l) participating in scientists' lectures and exchanging e-mail with them; and (2) visiting web sites about scientist and science, and exchanging e-mail with scientists at the sites. The results of the study can be summarized as follows: First, after participating in the program, children showed the significant decrease of several stereotypical items, such as facial growth of hair(bald hair beard), symbols of research, and age of the scientist. Second, the most popular source of the images was the visual media at the pretest but the source was changed to the visiting and participating scientist's lecture, and internet at the posttest. The latter items appeared a significant difference between the pretest and the posttest, The results indicate that the program is effective to decrease of children's stereotypical physical image of scientist.

Many people have recently posted about personal interests on social media. The development of the Internet and computer technology has enabled the storage of digital forms of documents that has resulted in an explosion of the amount of textual data generated; subsequently there is an increased demand for technology to create valuable information from a large number of documents. A text mining technique is often used since text-based data is mostly composed of unstructured forms that are not suitable for the application of statistical analysis or data mining techniques. This study analyzed the Meteorological Yearbook data of the Korea Meteorological Administration (KMA) with a text mining technique. First, a term dictionary was constructed through preprocessing and a term-document matrix was generated. This term dictionary was then used to calculate the annual frequency of term, and observe the change in relative frequency for frequently appearing words. We also used regression analysis to identify terms with increasing and decreasing trends. We analyzed the trends in the Meteorological Yearbook of the KMA and analyzed trends of weather related news, weather status, and status of work trends that the KMA focused on. This study is to provide useful information that can help analyze and improve the meteorological services and reflect meteorological policy.

The purpose of this study is to evaluate the technological competitiveness of the environmental industry with developed countries in order to establish an international market expansion strategy of the Korean environmental industry and technology. In order to evaluate the competitiveness of the environmental industry and technology, core technologies were classified by the environmental industry sectors based on the classification system of the domestic and international environmental industry and technology. After developing the evaluation index data, the Delphi analysis, journal and patent analysis, as well as the export and import analysis were carried out and the standardization analysis was performed on the index data. Moreover, the weights of each evaluation index were calculated using the AHP(Analytic Hierarchy Process) method and the evaluation results of competitiveness of the environmental industry and technology in Korea, the United States, the United Kingdom, Germany, and France were derived. As a result of the evaluation, the United States was rated with the highest technological competitiveness in all the environmental industry sectors, while Korea got the lowest technological competitiveness rating compared to the 4 developed countries. In particular, Korea got the lowest level of technological competitiveness in the sector of multi-media environmental management and development for a sustainable social system. Therefore, in order for the Korean environmental industry and technology to enter the global advanced market, it is necessary to strengthen the competitiveness through the development of the fourth environmental industry based on IoT(Internet of Things), cloud, big data, mobile, and AI(Artificial Intelligence), which are currently the country's domestic strengths.

The fandom phenomenon of political emotion originated from ideological conflicts between the conservative and the progressive amplifies social conflicts in South Korea in interpreting and accepting films as culture media. The purpose of this paper is to examine why the structure of political consciousness in South Korea is fandomized, what is the acceptance of cinema at the center of the controversy of political ideology, and what is the desirable attitude of film reception. I conducted a discourse analysis that closely examined the debates and articles on the internet regarding ,(2013) and ,(2014) which were controversial in terms of conservatism and progressivism. As a result, First, while Korean society has not constituted a consensus on modern and contemporary history, it has easily led the acceptance of cinema to the controversy surrounding the political ideology. Second, the failure of constructing consensual memories of modern and contemporary history has made the conservative and the progressive not acknowledge the other's achievements. Third, film interpretation and meaning production are ultimately the roles of the audience, and on interpretation, diversity should be respected but conformity would be rejected. Film acceptance and interpretation should focus on rational awareness of social reality and would reflect on the social ideal objectively.

The purpose of this study is to investigate how portal users recognize the role and function of the portal as a press. Furthermore, this study aims to analyze the pattern of portal news use among portal users and their recognition about replies to news. For this, we conducted online survey of 1,036 people aged from 15 to 45, who used portal site at least once a week. As a result, most users(70.8%) agreed that portal news played a role as a press with other media. In addition, six out of ten agreed that portal news set the agenda of society. These results suggest that portal users think highly of the social impact and responsibility of portal in society. However, about 40 percent of respondents said that they did not trust in information shown in replies to news and many replies to news were written by albeit. Six out of ten thought that replies to news were written by intention. Therefore, to manage the quality of replies to news is necessary to secure the credibility of portal news. As respondents use portal news often, they tend to think that portals are convenient to use and their social impact is very large, at the same time considering their sensation and commercialization. On the other hand, as portal users use the internet often, they tend to think that portals are convenient to use and their social impact is immense. However, there was no significant relationship between income and portal users' recognition of portals as the press.

Background : In Korea, the effort to control the spread of severe acute respiratory syndrome (SARS) has succeeded, but we have to maintain vigilance against SARS and other infectious diseases, because many experts warn that SARS may return or that other infectious agents could spread globally. The purpose of this study is to describe the degree of knowledge of hospital employees, assuming full responsibility for treating and attending to SARS suspected case, and to elucidate the attitude to SARS using questionnaires. Method : All employees of Kangwon university hospital were eligible for this study. We used validated questionnaires to survey demographic characteristics, the degree of knowledge of SARS, intention of treating and attending suspected cases, influence and effects of SARS on the community, and acquisition of information about SARS. Result : Based on the 251 completed surveys, out of 280 returned the score for knowledge about SARS was $72.0{\pm}13.7$, 50.6% responded positively about joining a SARS team, and 23.1% were opposed to the designation for quarantining. There was no relationship between the degree of knowledge of SARS and the attitudes to it. Most employees wanted to know how to manage SARS patients and how to prevent SARS. Conclusion : The attitudes to SARS were not affected by the level of knowledge of SARS. We suggest that national policies about SARS and other infectious diseases should be promulgated using the mass media and internet to provide information on rapidly spreading infectious agents, especially about the proper protocol for treating suspected cases and the appropriate steps to prevent or reduce the risk.

Many people use social network services as to communicate, to share an information and to build social relationships between others on the Internet. Twitter is such a representative service, where millions of tweets are posted a day and a huge amount of data collection has been being accumulated. Social mining that extracts the meaningful information from the massive data has been intensively studied. Typically, Twitter easily can deliver and retweet the contents using the following-follower relationships. Topic modeling in tweet data is a good tool for issue tracking in social media. To overcome the restrictions of short contents in tweets, we introduce a notion of reply graph which is constructed as a graph structure of which nodes correspond to users and of which edges correspond to existence of reply and retweet messages between the users. The LDA topic model, which is a typical method of topic modeling, is ineffective for short textual data. This paper introduces a topic modeling method that uses reply graph to reduce the number of short documents and to improve the quality of mining results. The proposed model uses the LDA model as the topic modeling framework for tweet issue tracking. Some experimental results of the proposed method are presented for a collection of Twitter data of 7 days.

Those who travel to another area for work or travel acquire cquire information through various media such as Internet websites before going to the area. The way to determine whether the information you collect is reliable is to go directly to that area. However, many users may overlook the date the post was posted. when you arrive at a delicious restaurant for a travel purpose, it can happen that the restaurant is gone. In order for Smartphone Users to be able to provide reliable information about a specific region through an application, it is possible to receive information from a specific local user using the application through crowd sourcing techniques. Collect suggestions from users when there are changes in the same area, rather than accepting indiscriminate information and when duplicate content exists, it is marked on the application map so that it can be viewed by other users. It provides not only simple restaurant information, but also area-specific information such as additional information about tourist attractions or information on restrooms to solve physiological phenomena that may occur in the area where they first arrive. Application users can get information about nearby public facilities and restaurants on a GPS basis.
