학위논문 국문초록 텍스트의 언어 특성

박보연 韓南大學校 敎育硏究所 2011 교육연구 Vol.19 No.1

본고는 최근 5년간 서울대학교 국어국문학과에서 나온 어학 관련 박사 학위논문의 국문초록을 대상으로 학위논문 국문초록 텍스트의 언어 특성을 단락 구조와 표현 형식, 응결성 장치를 중심으로 고찰한 논의이다. 단락 구조에서는 각 단락이 문장 개수 면에서 단락 구성 요건을 잘 갖추고 있음을 확인하였고, 구조는 대부분 '서론 → 각 장의 요약'의 형태로 나타나 단락의 개수와 각 단락의 내용이 학위논문의 장수. 각 장의 내용과 대응됨을 보았다. 그리고 표현 형식에서는 학위논문의 목적을 제시한 문장과 제목이 정형화된 구조를 지니고 있음을 알 수 있었고, 서술어는 기존의 학술텍스트 연구 결과와 다르게 '피동형', '가능형', '-고자 한다', '-기로 한다'의 표현은 별로 보이지 않고, 과거형 '- 었/았-'이 비교적 많이 사용되고 있음을 확인하였다. 마지막으로 응결성 장치는 '지시, 접속, 어휘적 응결'을 중심으로 살펴보았는데, 지시가 가장 보편적으로 사용되고 있었고, 지시나 접속이 사용되지 않는 경우에 어휘적 응결 장치가 사용됨을 알 수 있었다. 이상의 논의를 통해 학위논문 국문초록의 텍스트의 일반적인 언어 특성을 드러내 볼 수 있었다. The aim of this paper is to do examine several typical language features in abstracts of dissertations. The materials analyzed are limited to the Korean abstracts of language-related doctoral theses come out from the department of Korean Language and literature of Seoul National University for 5 years recently. To capture the typical features in abstracts of dissertations, I would focus on the paragraph structure, forms of expression and cohesion devices. First, in the paragraph structure, we could know the Korean abstracts have mainly 'introductory → summary of each chapters' structure. The number of paragraphs and chapters are almost same. The contents of paragraph would correspond to those of dissertation. Secondly, in the forms of expressions, we could know the title and the sentence which presenting the object of dissertation were represented by fixed structures. 'passive form', 'possibility form', ' -기로 하다', '-고자 하다' did not appear well, and the past form '-았/었-' showed much. This results differ from the existing studies based on academic text because abstracts have their own property. Lastly, the cohesion devices are investigated as reference, conjunction, lexical cohesion. The reference was the most commonly used. The lexical cohesion was shown only when the reference or conjunction were not used.

2.9% 과산화수소를 함유한 부착형 미백제의 임상적 효능과 안정성에 관한 연구

박은숙,성소래,홍성태,김지은,이소영,황수연,이신재,진보형,손호현,조병훈 大韓齒科保存學會 2006 Restorative Dentistry & Endodontics Vol.31 No.4

2.9%의 과산화수소를 함유한 시험용 부착형 미백제(Medison dental whitening strip, Samsung medical Co.,Anyang,Korea)를 실험군 피험자 23명, 시험용 미백제에서 과산화수소를 제외한 동일한 제재를 대조약으로 대조군 피험자 24명에게 매일 1시간 30분씩, 2주간 적용하여 임상적 효능과 안전성을 평가하였다. 미백 효과는 Shade Vision, Chroma Mete 및 Vitapan classical shade guide를 이용하여 색변화를 측정하여 다음과 같은 결론을 얻었다. 1. 실험군에서의 전체 치아의 색변화량(ΔE^(*))은 세 가지 측정법에서 모두 대조군에 비해 통계적으로 유의한 차이를 보였고 (p < 0.05). 쉽게 인지할 수 있는 정도였다. 2. 색변화는 색좌표 상에서 명도의 증가와 녹색조 및 청색조로의 변화에 의해 얻어졌다. 3. 치아별로는 어두운 견치의 색변화량이 가장 컸고, 측절치, 중절치 순으로 감소하였다. 4. 47명의 피험자 중 5명이 경도의 과민증을 경험하였으나 곧 완화되었다, 치은염증지수와 전기치수검사 결과 시험 전후에 차이가 없어 안전성을 확인하였다. This study evaluated the effectiveness and safety of an experimental bleaching strip (Medison dental whitening strip, Samsung medical Co., Anyang, Korea) containing 2.9% hydrogen peroxide. Twenty-three volunteers used the bleaching strips for one and a half hour daily for 2 weeks. As control group, the same strips in which hydrogen peroxide was not included were used by 24 volunteers with the same protocol. The shade chang (ΔE^(*), color differnce) of twelve anterior teeth was measured using Shade Vision (X-Rite Inc., S. W. Grandville, MI, USA), Chroma Meter (Minota Co., Ltd. Osaka, Japan) and Vitapan classical shade guide (Vita Zahnfabrik, Germany). The shade change of overall teeth in the experimental group was significantly greater than that in the control group (p < 0.05) and was easily perceivable. The change resulted from the increase of lightness (CIE L^(*) value) and the decrease of redness (CIE a^(*) value) and yellowness (CIE b^(*) value). The shade change of individual tooth was greatest in canine, can smallest in central incisor. The safety of the bleaching strip was also confirmed. 〔J Kor Acad Cons Dent 31(4):269-281, 2006〕

제2형 당뇨병 환자에서 우연히 발견된 기종성 방광염 1례

Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.

권계철,임춘화,김문희,박연보 충남대학교 의과대학 지역사회의학연구소 2001 충남의대잡지 Vol.28 No.1

Background : The application of the delta check in tests in general chemistry detects both random and clerical errors, thus enhancing the reliability of tests. However, since this approach adds the burden of confirming the results to the laboratory, it has the disadvantage of lengthening the turn around time of tests. We speculated that an online delta check system needed to reduce the turn around time. We developed delta quality control system and evaluated its effectiveness of quality control in clinical chemistry. Methods : We developed an online delta check system based on the client-server paradigm. We used IBM PentiumⅢ PC as server and as clients. The database system used was powerbuilder 6.0. Results : In the system we developed, delta screening was performed when test results were input to the computer. The decision over the delta screening was made by comparing it against patient's clinical information and cumulative results within the same screen. Conclusions : The developed delta check method made it available to reduce the turn around time previously spent on delta screening by eliminating the batch processing of tests which was needed in previous approaches separate query cumulative results and patient's clinical informations for screening purposes.

Study on the Effects of Ultrasonic Wave for the Effective Hydrogen Generation by Electrical Discharge Plasma Process

Park Jae-Youn,Cong Nghi-Vu,Han Sang-Bo,Kim Jong-Seok,Park Sang-Hyun,Lee Hyun-Woo,Lee Su-Jung The Korean Institute of Electrical and Electronic 2006 전기전자재료학회논문지 Vol.19 No.6

The research was tried to investigate the hydrogen generation from water by the pulsed power plasma process. Hydrogen was generated by way of the electrical pulse power discharge process with the ultrasonic wave. The yield on the hydrogen generation was also studied with and without operating the ultrasonic generator, in which the applied high voltage was varied from 10 kV to 15 kV. Nitrogen and argon gases were used as working gases. As the results, the generation yield using the pure nitrogen gas is better than argon and mixed gases such as argon and nitrogen. Hydrogen concentration are significantly increased when the ultrasonic generator was operated with the electrical discharge simultaneously. It is increased with increasing the applied ultrasonic level as well.

The cognitive loci of the display and task-relevant set size effects on distractor interference: Evidence from a dual-task paradigm

Park, Bo Youn,Kim, Sujin,Cho, Yang Seok Springer - Psychonomic Society 2018 ATTENTION PERCEPTION & PSYCHOPHYSICS Vol.80 No.2

<P>The congruency effect of a task-irrelevant distractor has been found to be modulated by task-relevant set size and display set size. The present study used a psychological refractory period (PRP) paradigm to examine the cognitive loci of the display set size effect (dilution effect) and the task-relevant set size effect (perceptual load effect) on distractor interference. A tone discrimination task (Task 1), in which a response was made to the pitch of the target tone, was followed by a letter discrimination task (Task 2) in which different types of visual target display were used. In Experiment 1, in which display set size was manipulated to examine the nature of the display set size effect on distractor interference in Task 2, the modulation of the congruency effect by display set size was observed at both short and long stimulus-onset asynchronies (SOAs), indicating that the display set size effect occurred after the target was selected for processing in the focused attention stage. In Experiment 2, in which task-relevant set size was manipulated to examine the nature of the task-relevant set size effect on distractor interference in Task 2, the effects of task-relevant set size increased with SOA, suggesting that the target selection efficiency in the preattentive stage was impaired with increasing task-relevant set size. These results suggest that display set size and task-relevant set size modulate distractor processing in different ways.</P>

Chemical Fungicides and Bacillus siamensis H30-3 against Fungal and Oomycete Pathogens Causing Soil-Borne Strawberry Diseases

Bo Reen Park,Hyun Jin Son,Jong Hyeob Park,Eun Soo Kim,Seong Jin Heo,Hae Ree Youn,Young Mo Koo,A Yeong Heo,Hyong Woo Choi,Mee Kyung Sang,Sang-Woo Lee,Sung Hwan Choi,Jeum Kyu Hong 한국식물병리학회 2021 Plant Pathology Journal Vol.37 No.1

Chemical and biological agents were evaluated to in- hibit Colletotrichum fructicola, Phytophthora cactorum, and Lasiodiplodia theobromae causing strawberry dis- eases. Mycelial growths of C. fructicola were gradually arrested by increasing concentrations of fungicides pyraclostrobin and iminoctadine tris (albesilate). P. cac- torum and L. theobromae were more sensitive to pyra- clostrobin compared to C. fructicola, but iminoctadine tris (albesilate) was not or less effective to limit P. cac- torum or L. theobromae, respectively. Bacillus siamensis H30-3 was antagonistic against the three pathogens by diffusible as well as volatile molecules, and evidently reduced aerial mycelial formation of P. cactorum. B. siamensis H30-3 growth was declined by at least 0.025 mg/ml of pyraclostrobin. The two fungicides additively inhibited mycelial growths of C. fructicola, but not of P. cactorum and L. theobromae. B. siamensis H30-3 vola- tiles led to less growth of C. fructicola than one reduced by the fungicides. Taken together, in vitro antimicrobial activities of the two fungicides together with or without B. siamensis H30-3 volatiles may be cautiously incorpo- rated into integrated management of strawberry dis- eases dependent on causal pathogens.

TSH 자극에 의한 FRTL-5 세포에서 p66 Shc의 발현 조절 기전

박영주,박은신,김태용,이윤용,이선화,박도준,신찬수,박경수,김성연,이홍규,조보연 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.1

연구배경: 갑상선종은 임상적으로 매우 흔하게 나타나지만, 아직까지 그 발생기전에 대하여 알려진 바가 적다. 갑상선 세포의 TSH 수용체 신호 전달 체계가 갑상선종의 발생에 중요한 역할을 할 것으로 생각되고 있으나, 기존에 잘 알려진 신호전달 기전인 AMP/A 단백질 활성화효소 (PKA) 체계나 PKC 체계만으로는 설명하기 어려운 점이 많다. 최근 TSH가 갑상선 세포에서 p66 Shc 단백질의 발현 증가를 유도하는 것이 보고되어, p66 Shc이 TSH에 의한 세포 증식 신호전달에 있어서 중요한 역할을 담당할 가능성이 시사되었다. 목적: 본 연구에서는 TSH 자극에 따른 갑상선 세포에서의 p66 Shc의 발현 변화를 관찰하여, p66 Shc 단백질과 갑상선 세포의 증식 신호와의 연관성을 알아보고자 하였다. 또한 TSH가 p66 Shc 단백질의 발현을 조절하는 것과 연관된 신호전달 과정을 살펴보아, TSH의 p66 Shc 발현 조절 기전을 밝히고자 하였다. 방법 및 결과: FRTL-5 세포에서 TSH에 의해서 p66 Shc의 발현의 증가하고, TSH를 제고하였을 때에는 다시 기저 수준으로 감소하였다. TSH에 의한 p66 Shc의 발현 증가는 TSH 수용체 차단항체에 의하여 경쟁적으로 억제되었다. TSH에 의한 p66 Shc의 발현은 TSH를 처리한 시간과 농도에 의존적으로 증가하였고, 이러한 현상은 p66 Shc mRNA의 발현에서도 동일하게 관찰되었다. 콜레라 독소는 p66 Shc의 발현을 증가시켰으나 백일해 독소는 TSH에 의한 p66 Shc의 발현에 아무런 영향을 미치지 못하였다. cAMP/PKA 자극제(8-bromo-cAMP, forskolin)를 처리하였을 때 p66 Shc의 발현이 증가하고 cAMP/PKA 억제제(H89)에 의하여 TSH에 의한 효과가 억제되었으나, C단백질 활성화 효소 억제제(PMA, GF109203X)는 아무런 영향을 미치지 못하였다. 결론: FRTL-5 세포에서는 TSH 자극에 의존적으로 p66 Shc의 발현이 조절되었으며, 이러한 TSH의 p66 Shc 발현 조절은 주로 TSH 수용체 - Gs 단백질 - adenylate cyclase - cAMP - PKA의 신호 전달 경로를 통하여 이루어지는 것으로 생각되어진다. Background: Thyroid goiters are very common, however, the mechanism of development is not fully understood. A TSH receptor has been known to activate two different signaling pathways the cAMP/protein kinase A(PKA) and phospholipase C(PLC)/protein kinase C(PKC) systems. However, both systems are limited in the degree to which they explain the discrepancy between a goiter and TSH receptor activation. It has recently been reported that the expression of p66 She was increased by TSH stimulation in thyrocytes, suggesting that the p66 Shc molecule may play a critical role in the transition of the TSH-induced growth signals. Methods & Results: In this study, we examined the expression of p66 Shc by stimulation of TSH, and the regulatory mechanisms of the TSH-induced expression of the p66 Shc in FRTL-5 cells. In FRTL-5 cells, TSH could increase the expression of the p66 Shc, and the this expression was decreased to basal levels after the removal of TSH. The TSH-induced p66 Shc expression was competitively inhibited by TSH receptor blocking antibodies. The increments of the expression of the p66 Shc protein caused by TSH were both time and concentration dependent, and it was same in the mRNA levels. Cholera toxin increase the expression of the p66 Shc, while pertussis toxin did not. The activators of the cAMP/PKA pathway (8-bromo-cAMP and forskolin) also stimulated the expression of p66 Shc, and the PKA inhibitor H89 decreased the expression, while the inhibition of the PKC pathway by GF109203X, or PMA, affected the expression of p66 Shc very little. Conclusion: Our data suggests that p66 Shc may play an important role in regulation the growth of thyrocytes. The TSH receptor - Gs protein - adenylate cyclase - cAMP - PKA pathway mainly mediates the TSH effects on the expression of p66 Shc molecules (J Kor Soc Endocrinol 18:45∼55, 2003).
