Nitrogen loading from domestic, agricultural and industrial sources can lead to excessive growth of macrophytes or phytoplankton in aquatic environment. Many studies have used stable isotope ratios to identify anthropogenic nitrogen in aquatic systems as a useful method for studying nitrogen cycle. In this study to evaluate the precision and accuracy of denitrification bacteria method (Pseudomonas chlororaphis ssp. aureofaciens(ATCC® 13985)), three reference (I AEA-NO-3 (Potassium nitrate KNO₃), USGS34(Potassium nitrate KNO₃), USGS35(Sodium nitrate KNO3)) were analyzed 5 times repeatedly. Measured the δ¹⁵N-NO₃ and δ¹⁸O-NO₃ values of IAEA-NO-3, USGS34 and USGS35 were δ¹⁵N:4.7±0.1‰ δ¹⁸O:25.6±0.5‰, δ¹⁵N:-1.8±0.1‰ δ¹⁸O:-27.8±0.4‰, and δ¹⁵N:2.7±0.2‰ δ¹⁸O:57.5±0.7‰, respectively, which are within recommended values of analytical uncertainties. Also, we investigated isotope values of potential nitrogen source (soil, synthetic fertilizer and organic-animal manures) and temporal patterns of δ¹⁵N-NO3 and δ¹⁸O-NO₃ values in groundwater samples during from May to December. δ¹⁵N-NO3 and δ¹⁸O-NO₃ values are enriched in December suggesting that organic-animal manures should be one of the main N sources in those areas. The current study clarifies the reliability of denitrification bacteria method and the usefulness of stable isotopic techniques to trace the anthropogenic nitrogen source in freshwater ecosystem.

임보람 ( Borahm Lim ) 한국언어문화학회 2015 한국언어문화 Vol.0 No.58

This thesis aims to analyze the ethics and social norms of modern society focusing on Lee, Kwang-soo``s novel, 《Moojung》(1917). From late 19c to early 20c, Choseon society faced radical changes. Ethics and social norms which regulated individuals lost their position which they had before by failed to keep up with the changes of real life. Reactionism and radicalism arose at the same time at the same place. In other words, the whole society was plunged in confusion. Lee, Kwang-soo had sharp insight into social situation. 《Moojung》 which appeared in 《Mae-ilsinbo》 from January to June of 1917, is filled with writers intension for laying the cornerstone of new ethics and social norms in a transition period. This study analyzes the intension of Lee, Kwang-soo by focusing on ``sympathy(dong-jeong)``, and ``nationalism``. Two main purpose of this article are: First, the method of Lee, Kwang-soo that understanding ethical deadlock which Choseon faced. This is also related to define ethics and norms of modern society. Second, reconsider Young-Chae``s narrative which leads the plot of 《Moojung》.

『유정』에 드러난 사랑과 욕망의 문제 연구

임보람(Lim, Bo-rahm) 우리말글학회 2016 우리말 글 Vol.69 No.-

이광수의 소설에서 ‘사랑’은 언제나 사랑 그 자체를 초과하는 요소를 포함하고 있다. 그것은 사랑이라는 내밀한 감정이 인물의 윤리적 위상을 정초하는 문제와 직접적으로 관련되어 있다는 점에서 특히 그러하다. 민족주의자이자 계몽주의자라는 이광수의 자리를 고려할 때, 그의 서사가 목표하는 바는 비교적 명확하다. 그것은 모든 정념적인 동기들이 민족을 위한 대의 속으로 수렴되는 『무정』의 대단원이나, 중심인물의 죽음이 죄의식의 형태로 공동체 속으로 돌아오는『유정』의 결말 속에서 가장 분명하게 드러난다. 그러나 문제는 이광수의 텍스트를 ‘민족’과 ‘계몽’이라는 단일한 키워드로 파악하는데 곤란을 야기하는 ‘증상(symptom)’적인 지점들이 여전히 이들 작품 속에 남아있다는 데 있다. 이 글에서는 특히 1933년 《조선일보》에 연재되었던 장편 『유정』을 중심으로 이 ‘증상’의 문제를 살필 것이다. 『유정』에서 ‘최석’의 서사가 목적하는 바는 그의 무고한 죽음이 공동체에 야기할 도덕적 감화 혹은 회개라 하겠다. 그는 스스로 희생양이 됨으로써, 그를 궁지로 내몰았던 사람들에게 갚아야 할 빚으로 되돌아온다. 그러나 사랑이라는 내밀한 감정과 관련해 ‘최석’이 보여주는 기이한 행위들은 계몽이라는 목적으로 성급히 환원시킬 수 없는 문제적 지점들을 내포하고 있다. 여기서 특히 흥미로운 사실은, 자신이 저지르지도 않은 죄를 기꺼이 자신의 몫으로 떠맡는 ‘최석’의 행위 속에서 어떤 나르시시즘적인 욕망과 조우하게 된다는 것이다. 그는 억울하다고 말하는 대신 정말로 ‘정임’을 사랑하는 쪽을 택함으로써 스스로 죄를 만들어낸다. 그리고 이 열정이라는 죄를 극복하기 위한 고행의 과정 자체를 자신의 삶을 추동하는 욕망으로 구성한다. 이처럼 『유정』의 서사는 공동체를 향한 계몽의 외피를 입고 있지만, 아이러니하게도 그것을 추동하는 저변의 원리란 가장 사적인 욕망의 발로이다. 이 같은 사실은 이후『무명』과 『사랑』에서 드러나는 종교적 색채를 이해하는 데 하나의 단서를 제공해 준다. In Lee Kwang-Soo’s novels, ‘love’ always includes elements that exceed the love itself. This is especially true in a sense that the inner feeling of so-called love is directly related to the problem of laying the foundation of ethical status of people. Considering the position of Lee Kwang-Soo, a nationalist and an illuminati, the goal of his narration is relatively clear. Every sentimental motive is the denouement of 『Moojung』 that converges into the national cause, but it clearly shows in the ending of 『Yoojung』 where the death of a main character returns back to the community in the form of guilty conscience. However, the problem is that ‘symptomatic’ points that cause difficulties in understanding the texts of Lee Kwang-Soo as a single keyword as ‘people’ and ‘enlightenment’ is still remained in these works. This study will particularly investigate the ‘symptom’ around a full-length novel 『Yoojung』 which was published serially in《Chosun-I lbo》in 1933. The purpose of a narration by ‘Choi, Seok’ in 『Yoojung』is the moral influence or repentance of what his innocent death will cause in the community. He becomes the sacrificial lamb himself and returns back as a debt that should be paid back to the people who drove him into a corner. However, bizarre behaviors of ‘Choi, Seok’ in regards to the private inner feeling as love contain problematic points that cannot be restored precipitately. An interesting fact here is that ‘Choi, Seok’ meets a certain narcissistic desire in his behavior of undertaking a sin that he has not committed. He makes a crime himself by choosing to love ‘Jung Im’ truly than complaining of a false charge. And constructs the process of mortification for overcoming the sin of so-called passion as the desire that gives impetus to his own life. As said, the narration of 『Yoojung』 is clothed in the enlightenment of community, but ironically, the base driving principle is the expression of the innermost desire.

In order to evaluate the precision and accuracy using LA-ICP/MS, thirty major and trace elements were analyzed with 3 USGS SRMs. And we investigated correlation between metal concentrations in five species tree-ring and ambient air heavy metal pollution history in ambient air. Total thirty major and trace elements in three USGS basalt glass reference materials, BIR-1G, BCR-2G and BHVO-2G were determined using LA-ICP/MS. Calibration was performed using NIST glass SRM 610, 612 and 614 in conjunction with internal standardization using Ca. Relative standard deviation(RSD) of determinations was below 10% for most elements in all glasses under investigation. All the USGS SRMs showed negative correlations between RSD and concentrations for elements with logarithmic correlation coefficients ranging from -0.867 to -0.790. Furthermore, these values were similar results obtained in NIST glass SRM 610, 612, 614. In natural sample analysis, 7 heavy metals in 5 tree species(Platanus occidentalis, Salix koreensis, Chamaecyparis obtusa, Pinus densiflora, Ginkgo biloba) were determined using LA-ICP/MS, and calibration was performed using cellulose - matrix matched standards with ¹³C nomalization. Four tree ring series showed that the Pb and Fe accumulation rates were higher between '92~'99 except for Ginkgo sp., but other elements(Cr, Mn, Cd, Zn, Sr) varied depending on species, which was caused by the physiological process of element uptake and radial mobility. Pb and Cd concentrations in tree ring of Pinus sp. have correlated with the ambient air heavy metal monitoring data which showed the correlation coefficients of 0.879 and 0.579, respectively. Pb and Cd concentrations in tree-ring of Salix sp. and Platanus sp. showed positive correlation with coefficients of 0.671 and 0.825, respectively. Therefore, our results suggested that Pb and Cd concentrations of Pinus sp. can be interpreted in terms of ambient air heavy metal pollution history.

The purpose of this study is to develop a cultural instruction model for primary English education based on digital literacy using digital textbooks. To accomplish the objective, this study examined the importance and direction of cultural education in primary English education and analyzed the components of intercultural competence and digital literacy. On the basis of the literature review of language-cultural integrated education instruction models and digital literacy education instruction models, this study developed a five-step instruction model called MACER (Motivate-Activate-Communicate-Evaluate-Reflect) to integrate language-cultural instruction and digital literacy into English education, which is expected to be effectively applicable in the primary cultural education field. To enhance the validity of the MACER model, a survey was conducted. Then, this study modified and refined the MACER model. Finally, this study introduced steps that teachers can follow to show how the MACER instruction model could work in planning language-cultural instruction in primary English education.

The purpose of this study was to develop appropriate spelling writing instruction based on phonological awareness activities that teachers can use in parallel with textbooks to teach 3rd graders in elementary school. Eighteen 3rd grade students(9 males and 9 females) participated in the activities and 6 students were selected to investigate the characteristics of the development in their spelling writing skills. The results of the study showed that the instruction had positive effects on the development of students’ spelling writing skills. The study also showed that the instruction increased the confidence and interest of 6 students in English spelling writing. In addition, the students had a very high preference for word making activities using alphabet chips. These results drew the following conclusions. First, phonological awareness based spelling writing activities in the early reading stages should be conducted continuously in order for the students to better decipher, accurately read, and write new words. Secondly, the national curriculum based textbooks should present phonological awareness instructional materials. Finally, it is suggested that teacher training programs should be provided to support effective spelling writing instruction for the elementary English class.

The purpose of this study is to examine the concept and development process of Skyscraper architecture and clarify the importance of external design plan and the future orientation by means of the determinant factors of the facade form and case analysis by the determined factors, thereby suggesting better form of various external designs in terms of its role as a landmark, image improvement, and urban context. It analysed by searching for the cases of more than 50-stories Skyscraper architecture at home and abroad, dividing the form generation elements into floor plan, cross section, and elevation for its symbolic external design. More specifically, the form of floor plan was divided into rectangular, circular, polygonal, and transformational form, that of cross section into composition of mass and solid forms. We can find the trend of skyscraper exterior design which is gradually moved to non uniform design. In spite of increasing building construction cost, new skyscraper owner wants to show to advantage. Another new trend of skyscraper exterior design element is about eco-design. Contemporary Architects think about natural source of energy, like solar energy and wind energy. As a result new skyscraper shows its varied exterior design.

1인 가구의 급격한 증가는 전통적 가족해체와 시장구조의 변화를 초래하고 있으며, 1인 가구의 양극화 현상과 맞물려 주거공간의 공유를 포함하는 새로운 주거유형을 요구하고 있다. 이에, 1인 가구의 주거정책, 주거요구, 주거유형의 3가지 키워드를 중심으로 주거에 관한 탐색적 연구를 수행하였다. 총 36개의 학습자원(학술논문, 학위논문, 전문자료)을 대상으로 체계적인 내용분석을 수행하였다. 내용분석은 일반화가 어려운 연구주제 또는 분야에서 객관적인 연구동향 파악에 적합한 연구방법으로 유용하다. 또한, 설문조사를 통해 내용분석 결과에 대한 후속적인 검증작업이 진행되었다. 그 결과로 1인 가구 주거에 관한 정책적, 사용자 특성별, 건축 유형별 1인 가구를 위한 주거요구가 도출되었다. 특히, 5개의 1인 가구 주거유형이 심층적으로 분석되었으며, 그 결과로 우리나라 상황에 맞는 1인 가구 주거유형 개발을 위한 시사점이 탐색 및 제시되었다. 향후, 주거정책, 주거요구, 주거유형에 관한 보다 세분화된 연구수행이 필요할 것이다. The rapid increase in single-person households resulted in disintegrating traditional families and changing housing market structure. This study was performed to examine three keywords or research subjects such as housing policies, housing needs and housing types for the particular households. A total of 36 learning resources(academic theses, degree theses, professional reports) were explored for contents analysis, which has been known to be the most useful method to figure out a generalized tendency for such subjects. The results were proved via on-line based survey questionnaires. As a result, overall housing needs were analyzed based on political, user, architectural characteristics of single-person households. Particularly, 5 types of housing were deeply examined in terms of spaces, which then lead to creating a set of guidelines for future korean single-person households. A more specific effort should be contributed to purify housing policy, housing needs and housing types for that particular population.
