심재욱,리황부,김승수 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

Hydrodeoxygenation (HDO) is considered as one of the promising methods for upgrading bio-oil from pyrolysis by removal of the oxygencontaining groups. The bio-oil product from pyrolysis of lignocellulosic biomass is a complex mixture of aromatic compounds such as furfural, furanone, phenol and their derivatives. Among these components, furfural is one of the major compositions. In this study, the model compound of furfural underwent HDO in fixed-bed reactor over monometallic catalysts Pt, Ru prepared by incipient-wetness impregnation method. The catalysts were supported on γ-Al₂O₃. The effect of catalyst activity and stability on FMK at different reaction temperatures and metal loading were investigated. The 1 wt% Pt/γ-Al₂O₃ catalyst (calcinated at 500 °C) showed the high activity with 87.04% in furfural conversion at 350 °C. The produced gas and liquid was analyzed by gas chromatography (GC) with TCD/FID detector and GC-MS, respectively, to determine the product compositions.

혐오의 시대, 김유정 문학의 건강성과 돌봄의 윤리

심재욱,홍단비 어문연구학회 2024 어문연구 Vol.119 No.-

비참한 현실과 파행으로 점철된 김유정의 소설은 ‘가장 끔찍한 삶의 장면들’을 보여줌으로써 오히려 어떠한 두려움도 없이 ‘삶을 소망’하게 만드는, 니체적 의미에서의 ‘비극’적 소설이자 건강한 소설이라 할 수 있다. 김유정 소설의 인물들은 자신을 고통스럽게 하고 끝내는 삶을 포기하라고 요구하는 절망을 오히려 새로운 생활을 위한 창조적 계기로 긍정함으로써 굴종과 자기연민의 무거움으로부터 자신을 해방시키고 경쾌하고 자유롭게 살아가는 모습을 보여준다. 김유정의 소설 속 인물들과 마찬가지로 염인증자였던 김유정은 문학 행위를 통해 자신의 힘을 고양하고 절대적 고통을 삶의 창조적 계기로 전유한 건강한 인간이었다. 즉, 김유정은 ‘말더듬이’와 ‘염인증’에 맞서는 소설 쓰기를 반복하고, 이를 통해 고양된 힘으로 자기 삶을 긍정한다. 이러한 이해는 김유정에게 자기 돌봄의 기술이었던 문학이 곧 세계(타자)를 돌보는 일이 될 수 있음을 보여주는 것이기도 하다. 특히 김유정의 ‘비극’적 민중소설은 그 흘러넘치는 힘이 김유정 자신에게만 향하지 않고 건강한 독자(민중)라면 충분히 나눠가질 수 있는 것이라는 점에서 ‘돌봄의 확장’이라는 의미를 지닌다. 이런 의미에서 그동안 민중에 대한 사랑으로 한정되었던 김유정의 ‘사랑’, 김유정 자신도 끝내 명확히 하지 못한 ‘위대한 사랑’이란 자기를 긍정하는 힘, 그 힘의 흘러넘침으로서 타자를 긍정하는 힘, 그리고 생성변화의 세계를 아름다운 것으로 긍정하는 힘으로 볼 수도 있을 것이다. 건강한 삶과 관련하여 김유정 문학이 보여준 자기 욕망에 대한 긍정과 고통의 긍정, 그리고 자기 긍정의 가치는, 초연결성이 가속화하고 있는 현대사회의 무리화와 그에 따른 혐오의 증식이라는 문제에 맞설 수 있는 새로운 돌봄 윤리를 제시한다는 점에서 의미 있다. Kim Yu-jeong's novel is a 'tragic' novel in the Nietzschean sense and a healthy novel that makes one 'hope for life' without any fear by showing 'the most terrible scenes of life'. The characters in Kim Yu-jeong's novels rather affirm painful despair as a creative opportunity for a new life. And freed from self-pity, they live cheerfully and freely. Kim Yu-jeong, who ymptoms of hatred toward humans, was a healthy human being who enhanced his strength through literature and appropriated absolute pain as a creative opportunity in life. In other words, Kim Yu-jeong repeats his novel writing in which he confronts the ‘stutterer’ and the ‘ymptoms of hatred toward humans’, and through this, he affirms his own life with his uplifting strength. This understanding also means that for Kim Yu-jeong, his literature, which was a technique of self-care, can soon become a matter of caring for the world (others). In particular, Kim Yu-jeong's ‘tragical' novels have the meaning of ‘expansion of care' in that the overflowing power is not directed only to Kim Yu-jeong himself, but can be fully shared by healthy readers (people). In this sense, Kim Yu-jeong's ‘love', which has been limited to love for the people, and ‘great love', which himself could not clarify, are the power of affirming the self, the power of affirming others as an overflow of that power, and generative change. It may be seen as a force that affirms the world of the world as something beautiful. The affirmation of one's desires, the affirmation of pain, and the self-affirmation shown in Kim Yu-jeong's literature can become a new care discourse that can confront the problem of the grouping of a hyper-connected society and the subsequent proliferation of hatred.

앵커지지 흙막이 벽체의 합리적인 3차원 수치해석기법 적용에 관한 연구

심재욱,정상섬,이성준 한국지반공학회 2016 한국지반공학회논문집 Vol.32 No.4

This paper presents the results of 2D and 3D finite element simulations conducted to analyze the effects of excavationdepth (H), excavation width (L), and ground condition on the behavior of anchored earth retaining wall in inclinedground layers. The results of numerical analyses are compared with those of the site instrumentation analyses. Basedon the results obtained, it appeared that 2D numerical analysis tends to overestimate the horizontal displacement ofretaining wall compared to the 3D numerical analysis. When the excavation depth is deeper than 20m, it is found that2D and 3D numerical analysis results of excavation work in soil ground condition are more different from the resultsin rock ground condition. For an accurate 3D numerical analysis, applying 3D mesh which has an excavation widthtwice longer than excavation depth is recommended. Consequently, 3D numerical analysis may be able to offersignificantly better predictions of movement than 2D analysis.

This stusy was carried out to investigate correlation between spore germination of ginseng pathogens and organic matter content of soils, and to examine the effects of various soil amendments on the severity of ginseng root rot. The results obtained were as follows; There was an inverse relationship (r=-0.177) between F. solani and organic matter content, whereas there was a direct relationship (r=0.16) between C. destructans and organic matter content. A total of 32 soil amendments were applied to the soils to investigate their effects on the severity of ginseng root rot. In their effects on the ginseng root rot caused by F. solani, the lower disease indice were under 0.3 in calcium nitrate and potasium chloride, respectively as compared with the disease index of 2.4 in the nonamended control. Calcium nitrate was most effective in the control of ginseng root rot, indicating the low diease index of 0.2. On the other hand, urea was most uneffective, indicating the high disease index of 3.9. In their effects on the ginseng root rot caused by C. destructans, the lower disease indice were under 0.3 in pig bone, hen shell, ox bone, white ciover, pine sawdust and yonguarin (F.M.P + S.P.), respectively as compared with the disease index of 2.3 in the nonamended control. Pig bone was most effective in the control of ginseng root rot, indicating the low disease index of 0.1. On the other hand, calcium chloride was most uneffective, indicating the high disease index of 4.0. Therefore, these results indicated a highly significant difference(p=0.01) in F. solani and C. destructans, respectively.

본 연구에서는 최근 국내에서 사용이 증가하고 있는 2열 자립식 흙막이 공법에 있어서 안정성에 영향을 미치는주요 설계인자들을 분석하고 설계기준을 제안하기 위하여 현장적용 결과의 분석 및 3차원 유한차분 해석을 수행하였다. 지반특성에 따른 본 공법의 거동을 분석하기 위하여 사질토가 지배적인 현장과 점성토가 지배적인 2개의 현장에적용을 수행하였으며, 굴착에 따른 흙막이 벽체의 수평변위 및 휨모멘트를 분석하였다. 3차원 유한차분 모델링 기법의타당성을 검증하기 위하여 현장적용 결과와 비교・분석을 수행한 결과, 본 연구의 수치해석 모델링 기법은 본 공법의 굴착에 따른 거동을 합리적으로 모사하는 것으로 나타났다. 또한 흙막이 벽체를 구성하는 전열말뚝(엄지말뚝) 및 후열말뚝(억지말뚝)의 간격(S), 전열말뚝과 후열말뚝간의 거리(D), 굴착심도(H) 및 말뚝의 근입깊이(Z) 등, 본 공법의 주요설계인자들의 영향 정도를 분석하기 위하여 다양한 경우의 3차원 유한차분 모델링 및 해석을 수행하였다. 그 결과,굴착에 따라 발생하는 흙막이 벽체의 최대 수평변위는 전열말뚝 및 후열말뚝의 간격의 감소, 전열말뚝과 후열말뚝간의 거리의 증가 및 말뚝 근입심도의 증가에 따라 감소하였으며, 이러한 특징은 점성토 조건의 지반보다는 사질토조건의 지반에서 보다 명확하게 나타나는 것을 확인할 수 있었다.

[舊日本海軍 朝鮮人軍屬 關聯 資料(2009)]의 微視的 分析

심재욱 한일민족문제학회 2013 한일민족문제연구 Vol.24 No.-

日帝が恣行した「強制動員」は日帝植民支配の欺瞞的な行為を赤裸々に示されることが韓国歴史研究にとって非常に重要な意味があると思う。同時に大勢の韓国人の個人史にまで悪影響を及ぼし、60年余りが過ぎた今までも各々の人生に傷付いていて社会問題の一つとして残っていることから見ると、その問題の深刻性が十分分かる。しかし解放されてから60年余りが過ぎているうちに韓国社会はあの被害把握に対して無関心な態度で目を逸して来た。2004年11月「首相官邸所属の日帝強占下強制動員被害真相究明委員会」(以下委員会)の立ち上げを契機に関連研究と実体把握が以前より活発にして、研究が活性化することは大いに励みになる事だと言える。それにも関わらず、今なお強制動員に関する研究には多くの眼界がある。この限界を突破する作業として必要なのは直ちに今現在、国家記録院で所蔵している約48万人分に至る関連名簿資料である。この資料は戦時の動員過程と戦後の復員過程で強制動員の主体である日本から作成された資料と言う側面と、全体的な分析によって「いつ、どこ、いくら、どこに強制動員されてどんな被害を受けたか」のような強制動員に対する全般的な実体把握が出来ると言う側面ですごく意義深いと思う。それでも、これに対した研究分析は殆んどない状況である。本稿は強制動員の全体像を把握するために必要な基礎的作業で、2009年日本政府が「委員会」に直接提供した[舊日本海軍朝鮮人軍屬関連資料(2009)](以下「舊海軍軍屬資料(2009)」)に収録された各種文書の内容と性格について考察した。「舊海軍軍屬資料(2009)」は1991年に日本政府が提供して、現在は国家記録院で所蔵している[舊海軍軍屬身上調査表]を基にしている。しかし「海軍工員名簿」、[供託金文書]等多数の新資料を収録しているので今までの資料とは異なる新たな性格の資料だと思う。そして、本稿に書かれたように海軍軍屬動員に関して戦時と戦後に多くの文書が作成されている。ところが、韓国政府に提供されたのは[舊海軍軍屬身上調査表]に過ぎない。追加的に入手すべき抜落ち資料を把握した側面で本稿の研究の意義がある思われる。本稿で筆者が行われた作業は「軍屬動員」の把握を通じて強制動員の全体像を考察しようとする一連の連続的作業である。このような資料の内容と性格に対する分析を基にして、今筆者は当該資料のデータをエクセルのファイルに書き込んでデータ化する作業をしている。今後行う詳細な分析は、今まで確認されていない海軍軍屬動員の実体が探れる重要な基礎的作業になると思う。 ‘Forced Mobilization’ under Japanese colonialism has a significant meaning to Korean studies, considering it accurately represents the deceitfulness of Japan’s colonial rule. Forced Mobilization also made unwelcome changes in a number of Korean people’s personal histories and it is still a lingering social issue of Korea. However, Korea has dealt with the matter with indifference over the last 60 years since Korea’s liberation. It is highly encouraging to learn that the studies and investigations on ‘Forced Mobilization’ have been improved and carried actively out since the establishment of ‘the Commission on Verification and Support for the Victims of Forced Mobilization under Japanese Colonialism in Korea(henceforth ‘the Commission’)’ under Prime Minister in November 2004. Nonetheless, we still have the limits in the studies on Forced Mobilization. The study on the registers of the approximately 480 thousand Korean names owned by National Archives of Korea is quite important in order to overcome the limits. As the registers were recorded by Japan during the period of war and demobilization, it can play an essential role to find the actual conditions of Forced Mobilization, such as when, how many, from where to where, and how much damage the Koreans had to be received. However, the study and analysis are still insufficient. In this study, as a groundwork for getting the general idea of Forced Mobilization, I examined the contents and its features of ‘the Document of the Korean Employees in the Japanese Imperial Navy(henceforth the Document)’ that the government of Japan directly gave to the Commission in 2009. The Document is based on ‘the Table of the Civilian Employees in the Japanese Imperial Navy’ given by Japan and currently owned by National Archives of Korea. As the Document includes new information, such as ‘the List of the Naval Factory Worker’ and ‘the Documents of Deposit’, it could be considered as new and valuable data to study. One more achievement of this study is to find the missing materials to be returned later on. ‘The table of the Civilian Employees in the Japanese Imperial Navy’ was the only material offered to the government of Korea by among many missing documents recorded in the state of war and after the war. What I did in this study is a part of the ongoing researches aiming at understanding the big picture of Forced Mobilization by taking in the situation of the mobilization of civilian Employees. Based on the data and its analysis, I am currently working on making the database. Detailed further analysis would be a substantial groundwork to discover the unidentified reality of the mobilization of Civilian Employees in the Japanese Imperial Navy.
