정재완 시인 연구를 위한 예비적 고찰 ― 물음과 단서들

정민구 ( Jeong Min-gu ) 현대문학이론학회 2021 現代文學理論硏究 Vol.- No.85

정재완 시인은 광주 지역을 중심으로 문학 활동을 하면서 생전에 9권의 시집과 2권의 동시집을 발간하는 등 괄목할만한 문학적 성과를 이루어냈다. 아울러 1960년 『현대문학』으로 등단한 이래 다른 지역의 문인들과도 여러 동인을 결성하여 활발하게 교유하면서 지역문단의 외연을 넓히는 활동을 지속하였다. 이 논문에서는 시인의 문학적 생애를 정리하고 문학 활동을 검토하는 과정을 통해 지역문학이나 한국현대문학사의 공백과 결여를 보완할 수 있음을 환기하고자 하였다. 아울러 시인에 대한 본격적인 연구를 추동하기 위한 예비적 연구의 차원에서 몇 가지의 물음과 단서를 도출해 보였다. 침체의 시기를 둘러싸고 발생하는 시적 진정성의 문제, 시(집)과 동시(집)의 관계, 윤석중 문고에서 발견된 시집들, 시인의 아호에 내재한 문학적 교유 등이 그것이다. 이러한 예비적 연구를 통해 정재완 시인의 시 세계 전반을 규명하기 위한 실마리를 마련하고 지역문학(사)의 별자리를 구성하는 데에 보탬이 되고자 하였다. Poet Jeong Jae-wan produced remarkable literary achievements while working as a regional literary activist, publishing nine collections of poetry and two collections of children’s verse during his lifetime. In addition, since his debut with Hyŏndaemunhak in 1960, he has continued to expand the scope of regional literature by actively interacting with writers from other regions as literary coteries. This paper first summarized the literary life of the poet, and in this process, it evoked a point where the gaps and deficiencies in the history of regional literature or modern Korean literature can be filled. To this end, prior to a full-fledged study of the poet's literary activities, several clues were drawn as a preliminary work. They include issues of poetic authenticity surrounding the period of stagnation, relationships between (collections of) poetry and (collections of) children’s verse, his collections of poetry found in Yoon Seok-joong's bookshelf, and literary intercourse inherent in the poet's pen names. This preliminary study is expected to provide a basis for identifying the whole poetic world of Jeong Jae-wan and help form constellations of regional literature.

The purpose of this study was to examine the association perceived physical activity pattern and body mass index according to habitual internet usage among middle school student. Data were analyzed for 969 students who responded to self-reported base cross-sectional survey relating to socio-demographic variables, internet usage status, and a short version of the international physical activity questionnaire. Prevalence rate of physical activity status showed that 53.5% at 150 min/week under, 46.5% at 150min/week over. Prevalence rate of internet usage showed that 95.6% at normal group, 2.6% at potential group, 1,9% at addiction group. Prevalence rate of body mass index status of over weight according to internet usage status shoed that 83.1% at normal, 5.1% at potential, 11.9% at addiction. Prevalence rate of physical activity levels of 150 min/week under according to internet usage status showed that 93.8% at normal, 3.5% at potential, 2.7% at addiction. In comparison with the physical activity levels was significantly more likely potential internet usage (OR, 2.62; 95% confidence interval [95%CI], 1.09-6.47; p〈.05) and addiction usage (OR, 3.82; 95% confidence interval [95%CI], 1.24-11.75; p〈.05). The results revealed that physical activity levels and body mass index correlates of internet usage status. This finding suggest the necessity of developing specific strategies for physical activity intervention by internet addiction among middle school students.

Microscopic polyangiitis (MPA) is characterized by pauci-immune necrotizing small vessel vasculitis without clinical or pathological evidence of necrotizing granulomatous inflammation. The kidney is the most often affected organ in the majority of patients with MPA, and renal manifestations are usually the first symptoms. Glomerular capillaries are affected most often, resulting in necrotizing glomerulonephritis, usually in a crescent formation, with no or few immune deposits able to be demonstrated at the sites of vasculitis and glomerulonephritis. We report a case of microscopic polyangiitis in both legs with pitting edema in a 50-year-old female. Laboratory findings showed hematuria, proteinuria, and a positive peripheral antineutrophil cytoplasmic antibody. A renal biopsy revealed pauci-immune splitting and necrotizing capillary loop walls necrotizing vasculitis and membranoproliferative glomerulonephritis (MPGN). With a diagnosis of MPA, she has been managed with high dose steroid and cyclophosphamide. To our knowledge, this is the first reported case of MPA with MPGN.

목 적 : K562 세포의 방사선에 의한 세포사망은 mitoticcatastrophe 현상이 위주로 나타나지만 herbimycinA(HMA)에 의하여 apoptosis 반응이 촉진되는 반면 genistein에 의하여 두 가지 형태의 세포사망이 모두 억제된다.본 연구에서는 HMA와 genistein에 의한 K562 세포의 방사선 유도 세포 주기 조절 변화와 세포 사망 양상의 연관성을 조사하였다. 대상 및 방법 : 지수증식기의 K562 세포에 6 MV 선형가속기(Clinac 1,800 C, Varian)를 이용하여 200˜ 300 cGy/min의 선량률로 10 Gy를 균일하게 조사하였다. HMA와 genistein은 각각 250 nM와 25μM 농도로 방사선 조사 후 즉시 투여하였다. 실험에서는 세포 주기,조절인자의 발현 및 활성,노화 및 분화정도 등에 있어서의 시간에 따른 변화를 조사하였다. 결 과: 방사선 단독조사에서 K562 세포는 G2기의 정체를 보였으나 정상적인 p53을 가지는 세포와는 달리 지속적인 세포 주기의 정체를 보이지 않았다. G2 정체가 유지되는 동안 cyclin B1의 점진적인 증가를 관찰할 수 있었으며, 이는 염색체의 복제가 완료되지 않은 상태에서 M기로 진행하여 미성숙한 염색체 응축과 mitotic catastrophe 현상이 나타나는 것 과 일치 한다. 방사선 조사와 함께 HMA를 투여한 경우에는 G2 정체가 빠르게 해소되었으며 동시에 G1기에서 세포가 정체되는 양상을 보였다. 세포 주기조절인자 cdc2 kinase 활성증가와 cyclinE와 A 발현 및 CDK2 활성의 감소 등의 현상으로 설명되며,이는 apoptosis의 증가와 연관성을 갖는다.반면 genistein의 경우에는 cyclin B1과 cdc25C 발현 및 cdc2 활성 이 모두 감소하는등 G2정체를 계속 유지하였다.이와 함께 방사선에 의한 노화와 megakaryocyte로의 분화도 지속되는 것을 관찰할 수 있었다. 결 론: HMA와 genistein에 의한 K562 세포의 방사선 유도 세포사망의 변화는 세포주기 조절과 밀접하게 연관되어 있음을 확인하였다.이는 다양한 방사선 유도 세포사망의 기전을 이해하는 데 독창적인 모델을 제공하며,방사선을 이용한 암 치료법의 개발에 새로운 표적을 제공할 수 있을 것이다. Purpose: In our previous study, we have shown the main cell death pattern induced by irradiation or protein tyrosine kinase (PTK) inhibitors in K562 human myelogenous leukemic cell line. Death o f t he cells treated with irradiation alone was characterized by mitotic catastrophe and typical radiation-induced apoptosis was accelerated by herbimycin A (HMA). Both types of cell death were inhibited by genistein. In this study, we investigated the effects o f H MA and genistein on cell cycle regulation and its correlation with the alterations of radiation-induced cell death. Materials and Methods: K562 cells in exponentialgrowth phase were used for this study. The cells were irradiated with 10 Gy using 6 MeV Linac (200-300 cGy/min). Immediately after irradiation, cells were treated with 250 nM of HMA or 25 M of genistein. The distributions of cell cycle, the expressions of cell cycle-related protein, the activities of cyclin-dependent kinase, and the yield of senescence and differentiation were analyzed. Results: X-irradiated cells were arrested in the G2 phase of the cell cycle but unlike the p53-positive cells, they were not able to sustain the cell cycle arrest. An accumulation of cells in G2 phase of first cell-cycle post-treatment and an increase of cyclin B1 were correlated with spontaneous, premature, chromosome condensation and mitotic catastrophe. HMA induced rapid G2 checkpoint abrogation and concomitant p53-independent G1 accumulation. HMA-induced cell cycle modifications correlated with the increase of cdc2 kinase activity, the decrease of the expressions of cyclins E and A and of CDK2 kinase activity, and the enhancement of radiation-induced apoptosis. Genistein maintained cells that were arrested in the G2-phase, decreased the expressions of cycl in B1 and cdc25C and cdc2 kinase activity, increased the expression of p16, and sustained senescence and megakaryocytic differentiation. Conclusion: The effects of HMA and genistein on the radiation-induced cell death of K562 cells were closely related to the cell cycle regulatory activities. In this study, we present aunique and reproducible model in which for investigating the mechanisms of various, radiation-induced, cancer cell death patterns. Further evaluation by using this model will provide a potent target for a new strategy of radiotherapy.

이유 있는 반항

This paper is to survey the conditions of teen movies from 1989, when Happiness Does Not Come In Grades was made, to 1991, when The Marriage Life kicked off the fad of romantic comedy, and probe into the nature and meaning of those films. During the time Korea’s film industry, facing direct competition with films made in Hollywood, was forced to find an escape route. In order to survive the competition, it was in the process of making changes such as recruiting new personnels, searching new ways to finance and seeking new ways to produce and distribute films. In late 1980s Korea’s film industry was experiencing drastic change of situation like opening its market to foreign products as the Korean society was rapidly transforming itself into a consumer capitalism. That is when the phenomena of teem movies surfaced again, and just like in 1970s its fad survived only a few years. What distinguishes the teen movies of 1980s from the ones of 1970s such as Yalkae series or Never never series is the fact that those of 1980s actively reflected the social problem and suggested a way of solving teenagers’ agonies, so they enjoyed much attention from teenagers and continuous production. Happiness Does Not Come In Grades was the one that opened the gate. The teen movies produced in early 1990s commonly had characteristics like long titles, small pool of actors and actresses, development of story mixed with critical perspective towards the harsh reality of school and comical elements, and similar episodes. The teen movies seem to have been a mixed territory of newly introduced rational planning and production, and outdated mode of production without any clear plan. We can say the teen movies of this period led introduction and experiment of various genres of films that flourished in so-called the Renaissance period of Korean films from the late 1990s through 2000s. Among the films made in this short period only two, Happiness Does Not Come In Grades and Our Class Accepts Anyone Regardless of Grade, stand out, as many other similar films seem to have been produced with no distinctive qualities. Analyzing styles presented by Happiness Does Not Come In Grades and Our Class Accepts Anyone Regardless of Grade, I hope to specify the features and merits of the 1980s’ teen movies. The two films share with many other films the element of teenagers’ ‘revolt’ at home and school, but they actually ‘revolted’ against the 1980s’ mainstream commercial films not just in story but in stylistics. And I analyze the two films from the viewpoint of stylistic ‘revolt.’
