여름철 석유화학산단 대기오염물질 분포 특성 연구

정종현,김익산,오은하,이재령,김효성 대한환경공학회 2022 대한환경공학회지 Vol.44 No.5

목적:양자전이비행시간질량분석기(PTR-ToF-MS)를 탑재한 실시간 이동측정 차량을 활용하여 대기오염물질의 분포 특성 및 오염물질의 배출원 추적을 통해 석유화학산단 내 대기오염 정도를 파악한다. 방법:석유화학산단 내 연구지역을 새벽, 주간, 야간 각각 3회씩 측정하여 각 시간대 VOCs 분포 특성을 조사하고, 오염지도로 나타내었다. 배출원 추적은 이동측정으로 Hot spot(고농도 지점)을 찾고 고정측정하여 면밀하게 배출원을 추적하였다. 결과 및 토의:석유화학산단 내 연구지역을 측정한 결과 Acetaldehyde가 가장 높게 측정되었으며, 그 농도는 직접관능농도 3~5도 수준의 상당한 악취가 발생하는 것으로 확인되었다. 측정항목 대부분 하루 중 새벽 시간대에 가장 높은 농도를 나타냈고, 이 결과는 기온역전에 의한 오염물질의 정체가 원인인 것으로 판단된다. 이동측정 시 새벽시간대에 Hot spot을 찾을 확률이 높았으며, 측정 결과는 측정당시의 풍향, 풍속의 영향을 많이 받음을 알 수 있었다. 배출원 추적은 연구지역을 이동측정 한 후 가장 고농도로 측정된 지점에서 고정측정 하여 보다 더 명확한 오염우려지역을 선정할 수 있었다. 결론:석유화학산단 내 대기오염물질의 분포 특성 및 배출원 조사 결과, 아세트알데하이드가 주 오염물질임을 확인하였고 조사 지역 내 오염우려지역을 효과적으로 탐색할 수 있는 방법을 제시하였다. 이를 통해 배출원을 더욱 효율적으로 관리할 수 있을 것으로 기대된다.

유관순 표상의 창출과 전승 : 해방 이후 제작된 유관순 영화의 내러티브를 중심으로

정종현 동국대학교 한국문학연구소 2009 한국문학연구 Vol.0 No.36

Gwan-sun Yu was a woman titled Korean national hero as icon of the Samil Independence Movement(on Mar. 1, 1919) and as representative of sufferings and resistances in colonial era. Historically, the emblem of Gwan-sun Yu which symbolizes national sacrifice and resistance was formed primarily by Korean nationalist group, independent government faction and Ewha School alumni after the 1945 Liberation of Korea. A heroic life story on Gwan-sun Yu (authored by Yeong-taek Jeon, 1948; against a background of Gwan-sun Yu Memorial Foundation and Korea Bibliography Publishing Committee) and a film titled ‘Gwan-sun Yu’(directed by Bong-chun Yun, 1948) based on her life story become original texts for framework and popularization of Gwan-sun Yu's emblem that has been handed down to this generation of Korean society. In the Year 1948 texts of Jeon and Yun, the sacrifice of a bold Korean girl student from a mission school called Ewha School became construed in a sense of nationalist and Christian martyrdom, and took a position of ethical authority for national legitimacy. This way, her political symbolism complied with cultural state planning where ruling elites who dominated the establishment of independent regime for South Korea aimed to give Korean national essence to southern state. Yun's 2nd film release titled ‘Gwan-sun Yu’(released in 1959) formed a narrative on Gwan-sun Yu in association with historical memory on areas below the 38th Parallel(including Gyeongju). Here, a political mechanism of location works to identify ‘South Korean’ nation as homogeneous persons. Gwan-sun Yu's emblem after the April Revolution(Apr. 19, 1960) becomes a critical case that demonstrates conflicts and rivalry between state (government) and civil society. Yun's 3rd film release titled ‘Gwan-sun Yu’(1966) suggests an evolution of previous Gwan-sun Yu's emblem, which is a combination of civil self-images(pursuing universal values like freedom and philanthropy after the April Revolution) and enhanced nationalism(after the Korea-Japan Ministerial Meeting). Even in this period, Korean government was still committed to spotlighting Gwan-sun Yu as heroic figure to make propaganda for Korean nationalism and government-led racialism under the influence of the Cold War. In particular, Director Gi-deok Kim's ‘Gwan-sun Yu’(1974), a film produced under the rule of Revitalizing Reforms (Yusin) system and Emergency Measures, forms an emblem of Gwan-sun Yu which projects Yusin ideology in a combination of nationalism and patriarchal authority. In this film, Gwan-sun Yu is presented as a role model that internalizes the rules of ‘the Hwarang School’ established to educate contemporary teenagers in the ideology of Yusin, rather than as a heroine who resisted national injustice. 유관순은 1919년 3.1의 아이콘이자 식민지의 수난과 저항을 대표하는 여성 영웅이다. 민족의 희생과 저항의 상징인 유관순 표상은 해방 이후 민족주의 계열, 단독정부 수립파, 이화학원 동문들의 주도로 구성된 것이다. 유관순 기념사업회와 전기간행위원회를 배경으로 하는 1948년의 전영택의 전기, 이를 바탕으로 제작된 윤봉춘의 영화 「유관순」(1948)은 이후 한국 사회에서 전승되는 유관순 표상의 골격을 결정하고 대중화한 기원의 텍스트들이다. 전영택과 윤봉춘의 1948년 텍스트를 통해 기독교 미션 이화학당 출신 소녀의 희생은 민족주의적, 기독교적 순교로 의미화되었으며, 민족적 정통성의 도덕적 권위로 자리잡았다. 이러한 유관순의 정치적 상징성은 남한 단독정권 수립을 주도한 통치엘리트들이 남한 국가에 민족적 정수를 부여하고자 한 문화적 국가 기획에 부합하는 것이었다. 1959년 개봉된 윤봉춘의 두 번째 「유관순」 영화에서는 경주 등 38선 이남의 역사적 장소와 결부된 유관순 내러티브를 구성함으로써 ‘남한’ 민족을 균질화된 동일자로 구성하는 장소의 정치학이 작동하고 있다. 4ㆍ19 이후의 유관순 표상은 국가(정부)와 시민사회가 갈등하고 길항하는 양상을 보여주는 중요한 사례이다. 1966년 윤봉춘의 세 번째 「유관순」의 시나리오에는 4ㆍ19 이후 자유, 박애 등의 보편적 가치를 추구하는 시민적 자아상과 한일회담 이후 고양된 내셔널리즘의 열망이 결합된 유관순 표상이 제시되고 있다. 이 시기에도 국가(정부)는 여전히 유관순을 국가주의와 냉전 하의 관주도 민족주의를 선전하는 영웅상으로 제시하였다. 특히 유신헌법과 긴급조치 하에서 제작된 1974년 김기덕 감독 제작의 「유관순」에는 국가주의와 가부장의 권위가 결합된 유신 이데올로기가 투사된 유관순 표상이 구성되고 있다. 이 영화의 유관순은 불의에 저항한 영웅이라기 보다는 당대 청소년에게 유신 이념을 교육시키기 위해 설립했던 ‘화랑교육대’의 규율을 내면화한 역할 모델로 제시되고 있다.

‘근대초극’에서 ‘순수문학’으로 : 조연현 문학의 형성과 전개

정종현 동국대학교 한국문학연구소 2020 한국문학연구 Vol.0 No.63

이 글은 탄생 100주년을 맞은 비평가 조연현의 문학적 공과를 조명하는 것을 목적으로 한다. 조연현이 신체제기에 펼친 ‘비합리주의’의 비평은 그의 문학의 원형질을 형성했다. 식민지기에 형성된 그의 문학론은 해방 이후 비평론과 문학사 서술, 『현대문학』의 이념에 지속되면서 변용되었다. 이성과 합리를 맹신한 근대에 대한 비판은 서구 지성계에서도 발견할 수 있는 중요한 사상사적 흐름이다. 조연현의 비합리주의는 현실에서 일본 제국주의 이데올로기와 결부되거나, 해방 이후 순수문학을 특권화하며 부정적 유산으로 전락했다. 그렇지만, 그가 제기한 비합리주의의 문학은 한국 근대문학사상사의 중요한 한 과제였던 것이 사실이다. 그에 대한 비판은 이 중요한 과제를 끝까지 추구하지 못하고 자신의 정치적 행로를 정당화한 데 두어져야 할 것이다. 조연현의 삶과 문학은 한국문학에 여러 부정적 폐해를 남긴 것이 사실이지만, 사상사적 과제와 비평의 존재 방식, 그리고 문학 제도의 차원에서 여전히 탐구되어야 할 질문을 던지고 있다. The purpose of this writing is to illuminate the literary achievement in Jo Yeon-hyeon (趙演鉉) as a critic with facing the 100th anniversary of his birth. The criticism of ‘irrationalism’ that Jo Yeon-hyeon did spread in the new system era formed the archetype in his literature. His archetypal literature theory, which was developed in the colonial period, was transformed with being continued the theory of criticism and the narrative of literary history, the ideology of 『modern literature』 after the liberation. The criticism of modern times that had a blind faith in rationality and reasonableness is an important thought-history flow, which can be found even in the Western intellectual system. Jo Yeon-hyeon's irrationalism is connected with the Japanese imperialist ideology in reality, but was demoted to negative legacy with privileging pure literature after the liberation. However, it is a fact that the literature of irrationalism that he raised had been a critical task in the History of the Korean Modern Literature Thought. Criticism on him will need to be put in justifying his political journey with failing to pursue this significant task to the end. It is a fact that Jo Yeon-hyeon's life and literature left many negative harmful effects in Korean literature, but are throwing a question, which will need to be still explored in the dimension of a thought-history task, of an existing method in criticism, and of a literature system.

Broad substrate specificity of a hyperthermophilic α-glucosidase from Pyrobaculum arsenaticum

정종현,서동호,James F. Holden,김현석,백무열,박천석 한국식품과학회 2016 Food Science and Biotechnology Vol.25 No.6

Pyrobaculum arsenaticum is a hyperthermophilic archaeon that thrives at 95oC. This strain encodes a putative GH31 intracellular α-glucosidase (Pars_2044, PyAG) in its genome. The recombinant PyAG (rPyAG) was optimally expressed in Escherichia coli at 37oC for 4 h after IPTG induction. The purified rPyAG is a homotetrameric α-glucosidase that exhibited highly thermostable properties. Maximum p-nitrophenyl-α-D-glucopyranoside (pNPG) hydrolysis activity was observed at 90oC and pH 5.0. The enzyme mainly recognized the non-reducing end of the substrate, releasing the glucose unit. rPyAG also had broad substrate specificity, cleaving maltose (α-1,4-linkage), kojibiose (α- 1,2-linkage), and nigerose (α-1,3-linkage) with similar efficiency. Based on these results, rPyAG can be used to modify health-relevant sugar conjugates linked by α-1,2- or α-1,3-bonds.

탈력발작 유무에 따른 기면병 환자의 비교 : 임상변인, HLA-DQB1*0602, Hypocretin

정종현,홍승철,신윤경,한진희,이성필 大韓神經精神醫學會 2007 신경정신의학 Vol.46 No.1

Objectives : Narcolepsy is a sleep disorder, characterized by excessive daytime sleepiness, cataplexy, sleep paralysis and hypnagogic hallucination. Among these symptoms, cataplexy is one of the most pathognomonic symptoms in narcolepsy. This study was designed to investigate the clinical features, frequency of DQB 1 *0602 and CSF hypocretin levels in Korean narcolep-tics with cataplexy to compare with those who have not cataplexy. Methods : From August 2003 to July 2005, we selected 72 patients who have narcolepsy confirmed by nocturnal Polysomno-graphy and multiple sleep latency test (MSLT) as well as their history and clinical symptoms at Sleep Disorders Clinic of St. Vincent's Hospital, Catholic University of Korea. Patients were divided into 56 cataplexy-positive group (narcolepsy with cataplexy group) and 12 cataplexy-negative group (narcolepsy without cataplexy group). HLA typing was done in all patients for the presence of DQB 1*0602, and patients received spinal tapping to measure the level of CSF hypocretin. Clinical variables were examined by semi-structured interview for narcolepsy patients. Results : 1) In cataplexy-positive group, compared with cataplexy-negative group, the frequency ofHLA-DQB 1*0602 was found to be significantly increased (50 subjects, 89.3% vs. 8 subjects, 50.0%) (p=0.000). 2) tn 48 out of 56 cataplexy-positive patients (85.7%), hypocretin levels were decreased (≤110 pg/mI) or were below the detection limit of assay (≤40 pg/ml).However, only 6 out of 16 cataplexy-negative patients (37.5%) exhibited decreased hyopcretin level. The difference between two groups were statistically significant (p=0.000). 3) Cataplexy-positive group, compared to cataplexy-negative group, re-ported more frequent hypnagogic hallucinations (36 subjects, 64.3% vs. 4 subjects, 25.0%) (p=0.005). However, there were no significant differences in frequency or seventy of daytime sleepiness, sleep paralysis and demographic data. 4. In nocturnal polysomnography and MSLT findings, there were no significant differences in all sleep parameters between two groups. Conclusion : Higher frequency of HLA-DQB 1*0602, and lower hypocretin levels in cataplexy-positive groups than Cata-pelxy-negatives suggest that narcoleptics with cataplexy might be a etiologically different disease entity from narcoleptics without cataplexy. Additionally, Current criteria prevail for the diagnosis of narcolepsy need to be reclassified according to the presence of cataplexy or not.

양극성 우울증 정신약물치료의 현재와 미래

정종현,우영섭,박원명 대한정신약물학회 2008 대한정신약물학회지 Vol.19 No.3

This article reviews the characteristics and major pharmacological treatment modalities of bipolar depression, which is distinguished from unipolar depression by etiologic differences, symptomatic features, clinical courses, and treatment responses. Bipolar depression is often disabling and very challenging to treat. In acute and prophylactic phases, mood stabilizers such as lithium, divalproex, and lamotrigine are used as first-line treatment, unless the patient is psychotic or markedly dysfunctional. Carbamazepine and oxcarbazepine can be used as a second-line treatment or in a combination regimen. Depressive episodes that do not respond to mood stabilizers, as well as relapsing episodes despite prophylactic therapy, justify treatment with antidepressants. Many clinicians also advocate the early use of antidepressants and antipsychotics when depressive episodes are severe or psychotic. Selective serotonin reuptake inhibitors and bupropion are considered the first choices for use in combination with a mood stabilizer. Bupropion in particular yields stability against manic switches or cycle acceleration. Traditionally, clinicians have used antipsychotics as a combination option when treating patients with bipolar depression who exhibit psychotic features. However, extensive and well controlled recent studies have shown that atypical antipsychotics such as quetiapine, olanzapine, and an olanzapine/fluoxetine combination can yield therapeutic efficacy and good tolerability for treating bipolar depression with or without psychotic features. In particular, a randomized controlled trial (RCT) using quetiapine monotherapy to treat patients with bipolar depression yielded significantly reduced depressive symptomatology. Other atypical antipsychotics such as amisulpride, aripirazole, risperidone, and ziprasidone have yielded antidepressive efficacy, but no RCT trials have been conducted on patients with bipolar depression. Some preliminary studies have shown that newly developed agents such as dopamine agonist, agomelatine, riluzole, mefepristone, and uridine effectively improve mood symptoms among patients with bipolar depression. More extensive clinical trials are needed.

遊離端局部義齒 使用時 支台齒 動搖에 對한 Splinting의 效果(Ⅱ)

鄭宗鉉 광주보건대학 1986 論文集 Vol.11 No.-

The effect of splinting on abutment tooth distal movement was performed in vitro study. An acrylic resin mandibular model with missing 2nd premolars, molars and a removable partial denture framework were constructed. The roots of the canines, 1st premolars and edentulous ridges were coated with silicone rubber. A modified Ney Surveyor was used for vertical load application, and abutment tooth distal movement were measured with a dial gauge when four conditions of splinting methods were tested by applying unilateral vertical loadings. The results are follows; 1. The magnitude of abutment tooth distal movement on the non-load side was less 40∼69% than that occurred on the load side. 2. On the load side, reducing effect of splinting on abutment tooth movement in the condition of load side double abutment(30%), non-load side double abutment (10%), double abutments of both sides (40%) was compared with single abutments of both sides. 3. On the non-load side, reducing effect of splinting on abutment tooth movement in the condition of load side double abutment(5%), non-load side double abutment(22%), double abutments of both sides(59%) was compared with single abutments of both sides. 4. The magnitude of abutment tooth distal movement in the condition of double abutments of both sides was less 40∼59% than that in the condition of single abutments of both sides.
