박동길,Park, Dong-Gil 한국과학기술단체총연합회 1979 과학과 기술 Vol.12 No.3
과학자가 되려면 다른 학문에 비해 어렵고 특히 기초과학연구를 하는 과학자의 경우는 더욱 어려운 공부를 계속하여야 한다. 그러나 이것은 과학자 스스로 택한 고난의 길이기에 이들은 한결같이 과학자가 된 것을 만족하게 생각하고 있다. 과학자가 되기위해 험난한 인생의 가시밭길을 무수히 헤치고 살아온 박동길박사. 박동길박사는 약관 20세에 도일, 과학자가 되기 위해 살을 여의는 듯한 고생을 무릅쓰고 오직 학업에만 열중했다. 박동길박사가 과학기술에 관심을 갖고 지금까지 걸어온 배경과 지질학을 연구하게 된 동기를 알아보는데는 까마득한 박박사의 어린시절로 돌아가야 할 것 같다. 이래서 본지는 이번호부터 박동길박사를 모셨다. <편집자주>

Laparoscopic cholecystectomy has rapidly become th procedure of choice for most patients with symptomatic gallbladder disease. Many physicians, however, believe that the laparoscopic surgery may be contraindicated in patients presenting with acute cholecystitis. Its use in acute cholecystitis may be associated with highier costs and complication rates. It is not known which patients with acute cholecystitis are likely to require conversion to open cholecystectomy based on preoperative data or if a cooling-off period with medical therapy can diminish inflammation and increase the chance of successful laparoscopic cholecystectomy. Recently, a number of small clinical series have been published that suggest that laparoscopic surgery may in fact be performed safely in the setting of acute inflammation. Twenty two cases of laparoscopic cholecystectomy done by the authors, including 8 cases on acute cholecystitis, between 7/92 and 6/93 were reviewed. Data on cases of acute cholecystitis were prospectively collected on standardized data forms. The mean operation time for acute cholecystitis was 109 minutes(range 80∼140 minutes), and 63 minutes for chronic cholecystitis(range 30∼90 minutes). There was no conversion to open laparotomy on acute cholecystitis. Postoperative complication was one case of referred pain on right shoulder in acute cholecystitis. Postoperative mean hospital stay was 4 days in acute cholecystitis. We made following conclusion from our exeperience ad review of published reports ; 1. Laparoscopic cholecystectomy in acute cholecystitis is no more absolute contraindication for well trained and experienced surgeon. 2. The most important parameter in determining the feasibility of laparoscopic cholecystectomy in the setting of acute inflammation appears to be experience of the surgeon. Anatomical identification of ductal and vascular system is second most important parameter, and difficulty of grasping follows. 3. Although laparoscopic intervention in such patient is associated with a greater likelihood of conversion to open laparotomy, the incidence of major biliary and nonbiliary complications appears to be low. 4. These patients enjoy the same benefits(short hospital stay and early return to normal activities) of laparoscopic surgery as those undergoing elective surgery.

모형매립조를 이용한 산업폐기물 매립지의 안정화 조사 기초 연구
박동일,최석규,홍종순,장인용 대한환경위생공학회 1998 대한환경위생공학회지 Vol.13 No.3
An experimental research was conducted to establish primary data for the stabilization assessment of industrial wastes landfill with analysis of waste components and investigation of leachate and gas generation, using three sets of lysimeter as experimental apparatus. Comparing results of lysimeter from data of landfill, it is suggested that lysimeter of this study can be used to accomplish the stabilization assessment of the real landfill site. Moisture content was lower as landfill period was older and combustible component was the highest in lysimeter C. The C/N ratio of waste was 7.4~14.4 and, with the elemental analysis, the theoretical gas generation rate based on the modified Buswell equation was 0.47~0.49 $m^3/kg-dry$ waste in lysimeter C. Considering the C/N ratio of leachate, it is concluded that the addition of carbon source is needed to biodegrade leachate hereafter. Gas generation rate($m^3/kg-dry$ waste) from lysimeter A, B and C was 0.0009, 0.014 and 0.0067, respectively, and different from each other according to the landfill period of wastes. The results in this study show that the biodegradation of microorganism for stabilization of landfill was inhibited and more activated in acidogenic step than in methanogenic of anaerobic degradation.

박동열(Park Dong yeol)(朴東㤠,) 형태론 2016 형태론 Vol.18 No.2
본고는 한국어 인칭 실현 양상에 관한 목정수 (2014)의 저서 『한국어, 그 인칭의 비밀』 에 나타난 인칭 개념과 인칭 분석의 틀을 정신역학적 관점에서 재해석하는 것을 목적으로 한다. 먼저, 그의 인칭 개념은 비교언어학과 유형론적 관점에서 보편성을 가질 뿐만 아니라 기존 개념과 달리 광의적이다. 필자는, 이 광의의 인칭 개념을 가지고 그가 설정한 한국어 인칭체계는 보편적 적용이 가능한 체계이며, 저자의 ‘어미중심 문장론’과 ‘인칭중심 언어학’ 주장은 바로 넓은 인칭 개념에서 기인하는 것으로 보았다. 다음, 그의 전방위적 인칭 분석은 발생적 관점에서 재해석될 수 있다. 즉 한국어 인칭 양상은 잠재적 인칭 자질을 내포한 형태소 층위에서 출발하여 발생적으로 단어 층위, 문장 층위를 거치면서 각종 문맥의 영향을 받아 중층적으로 발현된 것이다. 따라서 필자는 좀 더 체계적 인칭 분석을 위해 각 층위에서 발생하는 인칭 작용을 세밀히 분석할 필요가 있다고 보았다. The objective of this article is to reinterpret the concept of person and the frame for the analysis of person shown in the book Korean language, Secret of the Person, written by Mok, Jungsu. First, unlike existing concept, his concept of person is broad and universal as well in the perspective of comparative linguistics and typology. We claim that Korean person system he established on the basis of this broad concept, can be applied universally and his argue about ‘inflectional ending-centered syntax’ and ‘person- centered linguistics’ is due to this large concept of person. Second his various analysis of person can be reinterpreted in the genetic viewpoint. That is, Korean person starts from the morpheme layer which involves a potential person figure and then goes through the word layer and the phrase layer in the genetic fashion to be realized with the effect of various contexts in multi-levels. Therefore we claim that it is necessary to minutely analyze the process of person rising which occurs in each layer for more systematic analysis.
