측정방법에 따른 나노셀룰로오스와 산화전분 도공지의 표면 거칠음도 특성 분석
김희원(Hee-Won Kim),오윤택(Yoon-Taek Oh),김형진(Hyung-Jin Kim),고영찬(Young-Chan Ko),박종문(Jong-Moon Park) 한국펄프·종이공학회 2019 펄프.종이技術 Vol.51 No.1
Cellulose is one of the constituents of plants and is an environmentally friendly resource with a semi-permanent supply and high biodegradability. CNF from cellulose is useful for various purposes. CNF has high aspect ratio and high specific surface area and it is excellent in mechanical properties and thermal stability, and it has shear-thinning flow characteristics. When CNF is coated on paper, it provides high barrier property with excellent network forming ability. The surface roughness of the coated paper is one of the characteristics that determine the quality of coated paper and printing. The surface roughness is measured by the stylus profiling, the air leak, and the optical image analysis methods. Each analysis method has certain characteristics, so surface roughness of coated paper was analyzed by those three methods and results were compared. After mixed coating of CNF and oxidized starch, the degree of roughness was increased in the probe method and the air leakage method when the coating weight and the amount of CNF were increased. The degree of roughness which is measured by Optitopo decreased when the mixed solution was coated. Because the range of roughness measured by each measurement method is different, it might give different tendencies.

The important properties of a tissue are softness, strength, and absorbency for performance. The softness is one of important properties, and an objective evaluation method is required for purchase decision because subjective feeling is not enough. Surface smoothness can be measured by a stylus profiling, an electron microscope, or an optical method. Even objective measurement methods may have different results depending on types of measurement methods. The softness of the toilet tissue and the facial tissue of two companies was measured after using the internal and external softener. The softness was measured by using the KES-SE-SR surface tester as a probe method and the fractal dimension theory was applied. The correlation between the softness results and two methods such as the tissue softness analyzer and image analysis were compared. Results of the tissue softness analyzer and image analysis showed that softness increased when using internal and external softeners, but FD values increased. When using internal and external softener, it was assumed that hydrogen bondings of fibers at tissue surface were disrupted and the fractal dimension value increased.

Increased Non-permeable areas which have resulted from civilization reduce the volume of groundwater infiltration that is one of the important factors causing water shortage during a dry season. Thus, seeking the efficient method to analyze the volume of groundwater in accurate should be needed to solve water shortage problems. In this study, two different watersheds were selected and precipitation, soil group, and land use were surveyed in a particular year in order to figure out the accuracy of estimated infiltration recharge ratio compared to Web-based Hydrograph Analysis Tool (WHAT), The volume of groundwater was estimated considering Antecedent soil Moisture Condition (AMC) and Curve Number (CN) using Long Term Hydrologic Impact Assessment (L-TH1A) model. The results of this study showed that in the case of Kyoung-an watershed, the volume of both infiltration and baseflow seperated from WHAT was 46.99% in 2006 and 33.68% in 2007 each and in Do-am watershed the volume of both infiltration and baseflow was 33.48% in 2004 and 23.65% in 2005 respectively. L-TFIIA requires only simple data (i.e., land uses, soils, and precipitation) to simulate the accurate volume of groundwater. Therefore, with convenient way of L-TKIA, researchers can manage watershed more effectively than doing it with other models. L-THIA has limitations that it neglects the contributions of snowfall to precipitation. So, to estimate more accurate assessment of the long term hydrological impacts including groundwater with L-THIA, further researches about snowfall data in winter should be considered.

한국 근현대사에서 가장 질곡이 많았던 시기는 일제강점기라고 할 수 있다. 특히 1920년대에 어느 정도나마 가능했던, 문학 작품에서의 투쟁의지의 형상화가 1930년대에는 시대적 탄압으로 인해 작품에 내면화된다. 따라서 1930년대의 리얼리즘 시인의 대표 문인인 이용악 시세계를 연구하는 것은 우리 문학의 지평을 넓히는 길이 된다. 1930년대 창작된 이용악의 작품 중에는 자연을 소재로 하여 주제를 형상화한 작품이 많은 비중을 차지한다. 그의 시의 소재로 작용하는 자연이란, 현실의 참상을 고발하는데 효과적으로 작용하는 매개이자, 부정적 현실에 대한 울분을 토로하는 소재였고, 희망의 세계를 함축하고 있는 소재이기도 했다. 현실의 참상을 고발하는 자연물은 낭만성과 비극성을 동시에 함축하는 매개로 기능하며 비극적인 현실의 상황이 더욱 강조되어 표현될 수 있도록 하였다. ‘풀벌레 소리’, ‘꽃’, ‘낙엽’ 등과 같이 아름답고 평화로운 자연물이 자아내는 낭만성은 동시대 여타 시인들에 비해 이용악의 작품에서 더욱 두드러지는 부분이라고 할 수 있다. 강·바다 이미지에는 부정적인 정서인 울분을 함축시키면서도 희망과 이상향이라는 긍정적인 의미를 내포하였다. ‘강’에 투영된 불안 의식은 울분과 질책으로 이어진다. 그러나 이용악은 이러한 이미지로 ‘강’의 이미지를 고착시키는 것이 아니라 ‘강’이 ‘바다’로 흘러간다는 속성으로부터 희망과 이상향의 이미지를 이끌어 내고 있다. 마지막으로 이용악의 시편들에서는 당대 현실을 극복할 수 있는 방안도 자연의 섭리에서 찾는 것을 확인할 수 있다. 특히 겨울잠을 자고 봄을 기약하는 ‘곤충’의 이미지와 순환하는 자연의 섭리를 매개로 현실 극복 의지를 드러내고 있다. 이 연구는 그간 이용악 시의 패러다임으로 작용했던 고향상실 의식에 편향된 연구에서 벗어나 입체적인 시각으로 이용악의 시세계를 고찰했다는 데에 의의가 있다. The period when Korea was the most vigorous in terms of modern history can be said to be during the Japanese colonial period. Particularly in the 1920s, it was possible to shape the will of struggle in the form of literary works. In the 1930s, however, it was internalized in the works due to the oppression existing during that time. Therefore, it is a way to broaden the horizons of our literature by studying Lee Young-ak’s poems, the representative of the realism poet of the period of the 1930s. In the 1930s, the works of Lee Young-ak’s poems were showcased by many works that feature centrally the theme of nature. The nature which acts as the material of his poetry was, primarily, a mediator that acted effectively in accusing the true state of reality. Secondly, it was a material way to express the despair of the negative reality. Third, it also implied that there existed world of hope. The natural object that indicates the reality functions as a mediator that simultaneously implies both romanticism and non-tragedy, so that the tragic state of reality can be expressed more emphatically. The romanticism of beautiful and peaceful natural objects, including examples such as ‘insects’, ‘flowers’, and ‘leaves’, are more prominent in Lee Young-ak’s Poems. The image of the river and the sea implicates a negative emotion, a sense of hope, as well as an ideal. The sense of anxiety projected on the ‘river’ leads to mourning and reproach. However, Lee Young-ak does not fix the image of the ‘river’ with these images, but instead draws the image of hope and utopia from the property by which the ‘river’ flows into the ‘sea’. Finally, in the Lee Young-ak’s Poems, we are presented with the opportunity to find a way to overcome the reality of the present via the providence of nature. Of most note, it reveals the image of the ‘insect’, which pledges spring to sleep, and the will to overcome the hardships of reality through the circulation of natural providence. This study is meaningful in that it examines the poetic world of the ushak from a stereoscopic perspective by deviating from the study biased toward the loss of hometown, which serves as a kind of paradigm of Lee Young-ak’s poetry of the era.

하이데거의 존재론적 돌봄윤리로 본 ‘가족’ 그림책의 인물 특징과 돌봄의 의미
김희원 ( Kim Hee Won ),권민균 ( Kwon Myn-gyun ) 한국아동교육학회 2021 아동교육 Vol.30 No.2
본 연구의 목적은 하이데거의 존재론에 대한 돌봄윤리를 토대로 ‘가족’ 주제의 그림책 읽기를 통해 삶의 주체로서 등장인물이 어떻게 표현되는지와 존재론적 돌봄윤리가 어떻게 나타나는지를 살펴보는 것이다. 분석대상 ‘가족’ 그림책은 유지연의 『엄마의 초상화』, 최혜진의 『아빠와 토요일』, 고은결 글, 이명환 그림의 『사랑하는 당신』이다. 연구 결과로 첫째, 삶의 주체로서 등장인물은 기투하며 적극적으로 살아가는 존재, 자연과 교감하는 존재, 사랑으로 돌봄을 실천하는 존재로 해석되었다. 둘째, 존재론적 돌봄윤리는 ‘존재 의미에 대한 물음으로서 돌봄’, ‘존재 진리의 터에 대한 물음으로서 돌봄’이 나타났다. 이러한 연구결과는 돌봄의 주체가 되는 부모와 유아교사에게 돌봄윤리에 대한 근원적 성찰과 인간존재에 대한 이해의 폭을 확장하여 돌봄 실천의 방향성을 제시한다는 점에서 의의가 있다. The purpose of this study is to read in Heidegger’s existence and care ethics how the characters in the ‘family’ themed picture books are represented as the existential subjects and how the care ethics can be applied to interpret the stories. The ‘Family’ themed picture books analyzed are Yoo Ji-yeon's 『Portrait of Mom』, Choi Hye-jin's 『Saturday with Daddy』, Ko Eun-gyeol's writing and Lee Myung-hwan's illustrated 『My sweet love』. As the result of the research, first, as the subject of life, the characteres were represented as the subjects who actively lived, interacted with nature, and practiced caring with love. Second, we can find existential care ethics as a question of the meaning of existence and as a question of the site of existence truth. These findings are meaningful in that they present the direction of care practice to parents and early childhood teachers who are the main agents of care, and that they can expand their reflection on care ethics and their understanding of human beings.
