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".

Jin, Long-Hu,Shin, Hwa-Yoan,Yoon, Seung-Hwan,Seong, Do-Hwan,Park, Chang-Shin,Lee, Tack,Yoon, Sang-Min Korean Continence Society 2011 International Neurourology Journal Vol.15 No.1

<P><B>Purpose</B></P><P>To compare the physical characteristics of detrusor overactivity (DO) induced by intravesical infusion of saline in awake, sham rats and rats with chronic spinal cord injury (SCI), by simultaneous registrations of intravesical and intraabdominal pressures.</P><P><B>Methods</B></P><P>Male Sprague-Dawley rats, normal or with a spinal vascular clip at the level of Th9, were investigated cystometrically 1 and 4 weeks after SCI. Intravesical pressure (IVP) and intraabdominal pressure (IAP) were recorded simultaneously to evaluate true DO. During the filling phase, the event of IVP rises, defined as increments that exceeded 2 cmH<SUB>2</SUB>O from baseline, were determined as DO according to the absence of simultaneous changes in IAP.</P><P><B>Results</B></P><P>All SCI rats exhibited DO during the filling phase, which was not shown in sham rats. The frequency and pressure of DO had a tendency to decrease with time. The DO frequency of SCI rats after 4 weeks (0.9±0.2 min<SUP>-1</SUP>) was decreased compared with that after 1 week (2.1±0.4 min<SUP>-1</SUP>; P<0.05). The DO pressure of SCI rats after 4 weeks (8.4±1.9 cmH<SUB>2</SUB>O) was decreased compared with that after 1 week (11.6±2.9 cmH<SUB>2</SUB>O; P>0.05).</P><P><B>Conclusions</B></P><P>Cystometric studies in awake male SCI rats showed some significant changes in bladder function after SCI. All SCI rats exhibited DO during the filling phase, and showed different physical characteristics of DO over the course of time. The neurological basis of these time-related changes remains poorly understood, but may provide important prognostic information about long-term urological management in SCI patients.</P>

대구광역시 정보화 교육현황과 개선방안

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.

Government is the source of vast amounts of information. But, most information created or collected by the government is not routinely disseminated to the public. However, with the passage of the Freedom of Information Act, from 1!398, the public can access to government information, and the people' right-to-know will be secured. Thus, the purpose of this study is, first, to examine the important feature of the Freedom of Information Act and its influence to local autonomy, and second, to provide the desirable direction for its operation. This study suggests that, first, the Act should be well organized and institutionalized, and second, willingness of the public officials' be strengthened, and third, there should be a to disclose government information strong support from the executive.

After a period of tourism stagnation due to the corona virus epidemic, Korea is preparing to lift self-isolation and PCR results. Accordingly, we designed a platform application that can connect consumers and suppliers of travel guides that can respond to the influx of domestic and foreign tourists. DB design and client design were made using NoSQL-based Firebase server, Android Studio, and Java language. The suggestion app provides location-based tourist recommendation and tourist information output using GPS, and tour guide matching service using user information.

This article describes the advanced state of the transition to a competitive electricity market and attempts to predict the model in which the transition to a competitive electricity will unfold over the next few years. Especially, the unification in Korea peninsula will requires more efficient electricity production and more equitable electricity distribution. We could find that electricity productions(nuclear powerplants) should be owned and operated by state or public enterprise as present system and electricity distribution be owned and run by private enterprise according to regional characteristics.

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.
