A pilot scale SBR (working volume, 20㎥) treating piggery wastewater was operated with real wastewater. The operation mode of intermittent feeding of raw water and sub-cycle with repeating anoxic-aeration conditions were adapted to avoid the high-strength nitrogen inhibition. In sub-cycle, aeration time for nitrification was tried to be controled with ORP and/or DO meter. The characteristics of control was somewhat different between ORP and DO. DO showed potential ability to detect complete ammonia oxidation point by the first order differential values or absolute value. Especially, DO was proved to be useful for high loading rates. ORP indicated the ending point of nitrification by the plateau appearing after bending point. Because ORP can be utilized as a diagnosis tool by its good sensitivity for the microbial condition in reactor, the simultaneous application of DO and ORP was recommended for the stable control of SBR.

색계(色界)의 한 연구 -박상륭의 『죽음의 한 연구』론

정도상 ( Do Sang Jeong ) 현대문학이론학회 2013 現代文學理論硏究 Vol.0 No.54

박상륭의 『죽음의 한 연구』는 한국문학이 개척하지 못한 색계(色界)를 탐구하고 형상화한 관념소설의 정수라고 해도 과언이 아니다. 색계가 공계의 비대립적 상대성의 세계가 되기 위해서는 색즉시공의 동시성과 전환, 그리고 그것을 추동하는 용(用)이 필요했다. 달마는 용의 핵심을 마음으로 봤지만 박상륭은 남근으로 보았다. 이것은 선어(禪語)와 소설의 차이일 뿐이었다. 이어 ‘나’는 확정된 존재(Being)가 아니고 ‘되어가는 존재(becoming)``라는 관점에서 볼 때 색신(色身)임이 분명했다. 하지만 공신(空身) 달마로부터 원효에 이르기까지의 인물들이 색신에 투영되어 있다는 것도 확인할 수 있었다. 유리와 읍내, 그리고 큰 형장으로 이어지는 색신의 삶과 색계의 주유는 결국 공계(空界)로의 이동이란 궁극적 목표 때문이 아니었다. 공계로의 이동이 모든 색신의 궁극적 목표가 아닌 이유는 공이란 깨달음으로 가는 불성(佛性 혹은 自性)의 도구에 불과하니 집착하지 말라는 붓다의 가르침이 때문이기도 했다. 박상륭의 『죽음의 한 연구』에는 이와같은 내용들이 ‘나’라는 인물을 통해 색계가 잘 형상화되어 있는 소설이었다. It is no exaggeration to say that Park Sang-ryung`s 『A Study on Death』 is the quintessence of an ideological novel which embodies the world of r?pa(=form) that Korean literature has never discovered before. In order for the world of r?pa to exist with the world of s?nya(=emptiness) in a non-oppositive way, the simultaneity and conversion of the both as well as the medium that drives them are required. Dharma saw "heart" as the key of the medium, but Park Sang-ryung saw men`s penis as the key. It is just the difference between words of zen and a novel. In the sense that myself(in the novel) is not defined as "being", but more of a "becoming", it is clear that "I" am the body of r?pa. However, I could see that a variety of individuals in the body of s?nya from Dharma to Won-hyo were also reflected in the body of r?pa. Eventually, the ultimate goal of the journey of the body of r?pa from Yury to the downtown and the place of execution was not to travel to the world of s?nya. The reason why the ultimate goal of all bodies of r?pa is not moving to the world of s?nya is partially because of Buddha`s teachings that we should not be obsessed with s?nya since it is just one of the methods that lead us to the realization. The void is not Nothing. Park Sang-ryung`s 『A Study on Death』 is a novel that well-describes these contents through the character "myself".

Purpose: We wanted to analyze the use of nutrition support for terminal cancer patients, the effect of discussing withdrawal of nutrition support and do-not- resuscitate (DNR) consent on the use of intravenous nutrition during the patient’s last week of life and at the time of death.Materials and Methods: The study involved 362 patients with terminal cancer from four teaching hospitals, and they all died between January 1 2003 and December 31 2005. The basic demographic data, the use of intravenous nutrition during the patient’s last week of life and at death, discussion of terminal nutrition withdrawal and DNR consent were evaluated.Results:In the week before death, the patients received artificial nutrition such as total parenteral nutrition (31%), intravenous albumin infusion (25%), and feeding tube placements (9%). A discussion concerning withdrawal of nutrition support was limited to 25 (7%) patients. DNR consent was obtained from 294 (81%) patients. None of the patients were directly involved in any of these decisions. The discussion about withdrawal of terminal nutrition and DNR consent with the patient’s surrogates did not have any effect on reducing the use of parenteral nutrition.Conclusion: The majority of patients dying of terminal cancer were still given potentially futile nutritional support. Modern clinical guidelines and ethical education about nutritional support at the end of life care is urgently needed in Korean medical practice to provide proper administration of terminal nutrition for end of life care.

도윤호,문태영,남상호 대전대학교 기초과학연구소 2002 自然科學 Vol.13 No.2

경상남도 양산시에서 반딧불이의 다양성과 분포를 조사하였다. 11개 지역에 3종이 확인되었는데, Hotaria papariensis (Doi) 파파리반딧불이가 4장소에서, Luciola lateralis Motschulsky 애반딧불이가 4장소에서, Lychnuris rufa (Olivier) 늦반딧불이가 4장소에서 기록되었다. 파파리반딧불이는 천성산, 금정산, 영축산등의 산기슭에서 관찰되었고 양산의 동남부 지역에 집괴분포하는 경향을 보였다. 애반딧불이는 천성산의 동측사면의 수답을 따라 선형분포를 보였다. 늦반딧불이는 산만한 분포를 보여 추후 자세한 조사가 필요할 것으로 생각된다. 이 3종의 반딧불이가 모두 분포하는 천성산 지역은 울산과 부산을 서로 연결할 수 있는 지리적 위치로 서식지 네트워크를 구축하면 반딧불이 집단 간에 유전자 교류가 가능할 것이다. It was investigated the dwersity and distribution of fireflies from Yangsan city. Hotaria papariensis (Doi), Luciola lateralis Motschdsky and Lychnuris rufa (Olivier) were observed respectively at 4 different spots, but 11 spots in total. H. papariemis was recorded at Mts. Cheonseong, Keumjeong and Yeongchuk, but was concentrated at the eastern part of Yangsan. L. lateralis was observed along waterlines crossing rice paddies. However L. rda was scatteredy found and should be investigated further for the factors regulating distribution. Mt. Cheonseong that all 3 species recorded is likely to act to support a biogeographical network to conserve the firefly-genepool in Busan, Ulsan and Yangsan.

成道慶 영남대학교 사회과학연구소 2000 社會科學硏究 Vol.20 No.1

행정정보화의 효율적 추진에 있어서 가장 기본적인 요건은 공무원의 정보기술활용능력의 향상이다. 이에 따라서, 지방자치단체들은 공무원의 전산화교육강화를 시정정보화사업의 핵심과제 중의 하나로 삼고 산하 전 공무원을 대상으로 정보화 사회/의 도래와 사무자동화에 따른 행정환경 변화에 능동적으로 대응하고, 정보화추진의 기반을 조성하기 위하여 다양한 정보화교육을 실시하고 있다. 본 연구는 대구광역시를 대상으로 정보화(전산)교육의 현황을 살펴보고 그 개선방안을 제시하였다. 분석결과, 대구광역시의 정보화(전산)교육은 추구하고자 하는 기대에 크게 못 미치는 것으로 나타났다. 정보화(전산)교육에 대한 만족도는 낮은 것으로 조사되었는데, 대부분의 조사대상자들은 원하는 시간에, 원하는 장소에서, 원하는 내용의 교육을 못하고 있는 것으로 나타났으며, 그리고 대체로 정보화(전산) 교육과정이 적절하지 않다고 평가함으로써 정보화교육의 개선 필요성을 보여주고 있다.

안와를 침범한 거대한 전두동 점액낭종 I 례 : 증례보고

도남용,박성용,박영균 朝鮮大學校 附設 醫學硏究所 2002 The Medical Journal of Chosun University Vol.27 No.2

The term mucocele was introduced by Rollet in 1896 and Onodi gave the first histologic description in 1901. Paranasal sinus mucocele is the slowly expanding benign lesion which can occur as a result of trauma and spontaneous obstruction of sinus ostium or ostial tract. Mucoceles most frequently ahse from the frontal sinus and anterior ethmoid air cells, Presenting with proptosis, frontal headaches and reduced ocular mobility, especially on upward gaze. Since it may destruct the adjacent bony structure by pressure, early diagnosis and proper treatment are necessary. Recently we experienced on huge mucocele involving frontal and anterior ethmoid sinus and expanding onto left orbit, which was treated with endoscopic surgical procedure.

최성규,김홍도 한국특수교육문제연구소 2001 특수교육저널 : 이론과 실천 Vol.2 No.1

The purpose of this study was to analyze the language categories of children with mental retardation in the application of dynamic language programs. Three children with mental retardation were participated to analyze the language categones. The dynamic language programs were developed to apply between normal children and the subjects. Three normal children who were attending same classes with the subjects used the programs to interact with the three subjects. The investigation design without any research design was utilized for experimental research. Total ten sessions were applied. The time of each sessions was thirty minutes. The language categories based on B. F. Skinner's verbal behavior such as echoic, mand, tact, intraverbal, codic, and autoclitic were collected from thc three children with mcntal retardation when the three children interact with the three normal children responded from the normal children’s asking by thc language programs. The results were that: (a) language categories were analyzed by the programs; and (b) the most frequently language was intraverbal, and the second frequency of the language responses was autoclitic, howcver, the other four language categories were not presented. Thcrefore. this study concluded that the intraverbal is most important language cate당 ory for the children with mental retarded 본 연구의 목적은 정신지체아동과 또래아동과의 상호작용 프로그램을 적용하여 정신지체이동의 언어유형을 분석하고자 하였다. 언어유형은 B. F. Skinner의 Verbal Behavior 역동적 이론에 기초한 복제, 명령, 지칭, 상호, 기호, 자발언어 등이다. 프로그램 적용 방법은 역동적 방법을 이용하여 접근하였다. 연구대상은 초등학교 특수학급에 재학중인 정신지체아동 3 명이었다. 정신지체아동의 또래 아동과의 상호적용에서 나타난 언어유형은 상호언어와 자발언어였다. 상호언어와 자빌언어의 증감은 상호 영향을 미치고 있었다. 따라서 상호작용을 통한 언어지도 방안이 정신지체아동의 언어지도의 기초가 될 수 있음을 본 연구결과는 시사하고 있다.
