국내 하천, 호소에 유입되는 오염물질 중 30% 이상이 농업 활동 등으로부터 기인한다. 정부 부처는 '04년부터 농업 비점오염원 저감 대책을 수립·시행하고 있으나 농촌 인구 고령화, 열악한 재정환경, 관행화·고착화 된 농법 등으로 인해 주민참여 및 대책 적용의 한계가 있었다. 금호강 상류 보현산댐 유역은 대부분 임야로 고현천 등 상류 하천변에 사과원이 밀집되어 있다. 또한, 유역면적이 32.16km²로 좁고, 유로 연장 5km 이내로 짧으며 하천 경사가 급해 강우시 토양 유실량이 많고 유출속도가 빠르다. 이러한 유역 특성상 상류 사과원은 '16년 보현산댐 담수 이후 매년 반복적으로 발생하는 녹조 등 수질 문제를 초래하는 주요 비점오염원으로 지역사회 이슈가 되었다. 이에 따라 K-water는 낙동강수계관리위원회 환경기초조사사업의 일환으로 지역주민들과 논의를 통하여 댐 상류 사과원에 친환경농법(심층시비)를 적용하고 수질 개선 효과를 분석하였다. 심층시비는 과수 주변 토양 천공 후 퇴비를 시비하는 친환경농법으로 표층시비에 비해 초기 강우유출 오염물질량을 저감하고 퇴비 사용량도 줄일 수 있다. 금번 연구에서 실제 운영 중인 농지('19년 24천평, '20년 27천평)을 대상으로 심층시비를 시범적용한 결과, 퇴비 사용량은 표층시비의 50% 수준으로 감소하였고 과수 생육 및 품질에는 큰 영향이 없는 것으로 나타났다. 강우 시 유출농도는 표층시비 대비 TOC 5.0~41.3%, T-P 4.0~57.3% 감소했다. HSPF 유역 모델링 분석 결과, 전체 과수원 중 70% 농지에 심층시비를 적용한 경우, 하절기 유역 T-P 유입부하량이 5.0~6.8%(소유역 최대 28.2%) 감소하는 것으로 예측되었다. 본 연구결과를 바탕으로 심층시비를 확대 적용하고 유역 수질관리에 기여하고자 한다.

With a view to grasping how media commercialization is understood and discussed in the media-related academic community, this study compares and reviews other researches on the commercialization process of Korean press. Full-fledged studies have been rarely performed on the history of commercialization, but similar or related studies have been conducted intermittently: One is the commercialization theory in 1933 and the other is the commercialization theory in the late 1960s. Both of them decided Korean press had been commercialized as a strategical option in the midst of political pressure. It gives a clue leading us to understanding on why Korean press shows partisanship which is pointed as one of social maladies. Korean press acquires less economic benefits if they play in the market than if political parties they support or share the same political interest take power, so they are a commercial press as well as a partially partisan press. In this context, commercialization of Korean press is still underway, and genuine commercialization hitting the balance with politicization may have yet to begin.

Aviation safety is the stage in which the risk of harm to persons or of property damage is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and risk management. Many accidents and incidents have been taking place since 2014, while there had been relatively safer skies before 2014. International civil aviation community has been exerting great efforts to deal with these emerging issues, thus enhancing and ensuring safety throughout the world over the years. The Preamble of the Chicago Convention emphasizes safety and order of international air transport, and so many Articles in the Convention are related to the safety. Furthermore, most of the Annexes to the Convention are International Standards and Recommended Practices pertaining to the safety. In particular, Annex 19, which was promulgated in Nov. 2013, dealing with safety management system. ICAO, as law-making body, has Air Navigation Commission, Council, Assembly to deliberate and make decisions regarding safety issues. It is also implementing USOAP and USAP to supervise safety functions of member States. After MH 370 disappeared in 2014, ICAO is developing Global Tracking System whereby there should be no loophole in tracking the location of aircraft anywhere in world with the information provided by many stakeholders concerned. MH 17 accident drove ICAO to install web-based repository where information relating to the operation in conflict zones is provided and shared. In addition, ICAO has been initiating various solutions to emerging issues such as ebola outbreak and operation under extreme meteorological conditions. Considering the necessity of protection and sharing of safety data and information to enhance safety level, ICAO is now suggesting enhanced provisions to do so, and getting feedback from member States. It has been observed that ICAO has been approaching issues towards problem-solving from four different dimensions. First regarding time, it analyses past experiences and best practices, and make solutions in short, mid and long terms. Second, from space perspective, ICAO covers States, region and the world as a whole. Third, regarding stakeholders it consults with and hear from as many entities as it could, including airlines, airports, community, consumers, manufacturers, air traffic control centers, air navigation service providers, industry and insurers. Last not but least, in terms of regulatory changes, it identifies best practices, guidance materials and provisions which could become standards and recommended practices.

The major purpose of this paper is to analyze the evolution of the presidential system in South Korea during the past three decades ever since the country's democratization in 1987 from the comparative institutional perspective. As imperial presidentialism during the so-called three Kim's era(1987-2003) disappeared right after the political retirement of the three Kims in 2003, then president-centered presidentialism emerged during the post-three Kim's era, since the country's recent three presidents possessed their relatively low-level of partisan power in terms of their control of National Assemblies and their respective presidents' parties during their presidencies. South Korea has now a strong possibility to transform the current president-centered presidentialism into the American-style separatist presidential system in the near future, since the country's National Assembly has continuously been making its efforts to function as an effective governing body being compatible with the American Congress. In addition, the country's judiciary branch has effectively been playing a political role like the US supreme court ever since the country's democratization in 1987. It is also emphasized that South Korea's civic society is currently playing as a guardian of democracy through its effective and responsive political participations in many public sectors for promoting civic liberties, public welfare, and other democratic values. South Korea now needs to carry out constitutional revisions, political reforms of legislative system, party system, and electoral system as well as correct some contradictory political understandings and habits in a way to transform the current president-centered presidentialism into American-style separatist presidential system in the near future.

The purpose of this study to empirically examine a smart work investment and job performance by change resistance. Firstly, There investigates mediating role of the communication between the smart work investment and the job performance. Secondly, It will identify the job productivity differences through a level of organizational change resistance that reduced smart work investment. The smart work is to provide the flexibility of time and location and is a working method to improve a work productivity of organization members. The introduction of smart work means the adoption of new organizational culture, institution and technology and requires a novel change of a custom and pattern on existing organization culture and institution because of transformation form of communication and collaboration. The method of this study adopts a structural equation model to test a mediating effect of communication and a moderating effect of change resistance level. This model confirms whether smart work investments provide a positive impact on communication and organizational productivity. In addition, I will classify a change resistance level of smart work by cluster analysis and then check a critical path difference of job productivity between each group. As a result, The organizational IT, institution and culture on the smart work investment appeared to important influencers in communication and also had a direct influence of individual performance. Also, The three independent variables of smart work investment have an indirect influence of individual and organizational performance through communication mediating variables. However, the organizational IT and institution as independent variables do not provide direct influence of organization performance. Nevertheless, two independent variables of organizational IT and institution have an indirect influence the organization performance through communication mediating variables. As a result of confirming a productivity of three groups on organization resistance, there was a difference the individual and organizational performance among groups. The low-level group of organizational resistance showed high coefficient value of performance compared to other groups. The group analysis implications, The smart work investment appeared significantly to revise the institution first, build culture secondly and advanced technology lastly. The theoretical implication from this study contributes an extension of social science theory through socio-technical systems, institution, culture, change resistance and job performance based on smart work. The practical implications explain the smart work success in step-by-step investment rather than radical investment as level management of change resistance. In future research, the smart work performance between private and public firms will analyze a difference of the organizational culture, institution, technology and performance.

The purpose of this study is to examine a direction for contents choice and transmission strategies of radio literature reading programs. For this, 129 picturebook contents used for EBS program of "children books for adults" in recent 6 months were collected and analyzed quantitatively and qualitatively based on Nicholajeva's societal and aesthetic approach. In terms of external literary elements, there were unequal distribution of published period, nation, company and genre. In terms of literary inner factors, they were excellently reflecting the stream and the tendency of modern children literature. Finally, in the process of turning visual texts into auditory texts, the program used diverse auditory transmission strategies. Based on these results, it is suggested that this program need to take into account reforming the contents selection practice to provide abundant literary experience for listeners and sophisticating the transmission effects adapted for a digital era.

The media, traditionally, serves to reinforce one's limited memory and transform those personal memories of society's members into collective memories. Notably, the mass media collects countless pieces of personalized memories for the creation of collective memories. Through the process of recollecting as well as recreating the past in the present, mass media exerts influence on the means the public appreciates and understands the history. Although numerous new medias like Internet overflows in today's society, television continues to stand firm as the salient means to construct the memories in daily lives. In this context, the research aims to analyze the televised news as the principal agent of memory producer to determine through which memories it recreates the $5{\cdot}18$ in today's media. The analysis of news values clarifies that every government placed distinctive news values on $5{\cdot}18$ within its historical context. Even so, such values were often fixed based on its relations to the existing political issues. Furthermore, through the discourse analysis, this research concludes that today's coverage of $5{\cdot}18$ is softening and becoming conventional.

Research on lexicon and language provides insights into the interests, values and practices of a community where individuals use the language. The International Classroom Lexicon Project, in which ten countries participated, identified own country's mathematics teaching and learning lexicons by investigating mathematics classroom instruction from teachers' perspectives in a speaking-oriented community. This study, as an extension of the International Classroom Lexicon Project research, investigated pedagogical lexicons used in 「Mathematics and Education」 journals specialized for Korean professional mathematics teachers published by the Korean Society of Teachers of Mathematics. Using the text mining approach, we also traced how these pedegogical lexicons have changed quantitatively over the past 10 years with a diachronic perspective. As a results, several novel terms were found in the writing-oriented community, which were not identified in the speaking-oriented community. In addition, we could discover some pedagogical lexicons have increased statistically significantly and some lexicons appeared(increased) rapidly across years. This implies the teacher community's values and zeitgeist by reflecting these changes in the sociocultural, incidental and social changing (i.e., periodical change) contexts. This study has value as a first step in understanding zeitgeist for mathematics education in Korean mathematics teacher community according to changes of times over the past 10 years. Also, this study contributes to the methodological insights: the text mining technique provides a methodological contribution to researching changes in interests, values and zeitgeist according to these changes in the times.
