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.

『죽음의 한 연구』에 나타난 마음에 관한 연구

정도상 ( Do Sang Jeong ) 현대문학이론학회 2014 現代文學理論硏究 Vol.0 No.57

박상륭의 『죽음의 한 연구』는 마음의 변화를 형상화한 관념소설이다. 모든 소설이 사람의 마음을 다루고 있기는 하다. 하지만 이처럼 본격적으로 마음을 다룬 소설은 일찍이 없었다. 마음에도 체(體)와 용(用)이 있다. 체는 마음의 형태이고 용은 마음의 작용이다. 몸이 마음의 집이고, 마음은 몸의 길인 것과 비슷한 논리이다. 마음의 체와 용은 색즉시공 공즉시색의 관계에 놓여 있다. 『죽음의 한 연구』에서 주인공 ‘나’의 마음은 네 단계로 전환을 일으켰다. 욕심에서 색심으로, 색심에서 무심으로, 무심에서 공심으로의 전환이 그것이다. 이는 주인공 ‘나’의 공간 이동과 일치한다. 유리와 읍내, 다시 유리에서 큰 형장으로 공간의 이동과 마음의 변화는 결국 공계로의 이동을 궁극으로 삼았기 때문으로 보여진다. 주인공 ‘나’는 공계에서 죽음이라는 공심을 선택한다. 박상륭의 『죽음의 한 연구』는 ‘나’라는 인물을 통해 마음의 변화와 그 이동이 아주 잘 형상화되어 있는 소설이었다. Park Sang-ryung``s 『A Study on Death』 is an ideological novel that embodies the change of human Minds. All novels contain stories of human Minds. However, there has not been such a novel which genuinely talks about the Mind on this deep level. Mind consists of substance and the medium. Substance is a form of the Mind, and the medium is a behaviour of Mind. This is the same logic as how human body works as a house of Mind, and Mind is a path that human bodies live through. Substance and the medium of Mind are in a relationship that align with the one of the world of rupa and the world of sunya. In 『A Study on Death』, the Mind of the main character "I" changes through four different parts. It changes from the Mind of kamaloka to the Mind of rupa, from the Mind of rupa to the Mind of immaterial world, and from the Mind of immaterial world to finally the Mind of sunya. This journey also aligns with the change of places that the main character "I" travel through. All the changes of places and Mind travel through Yury, the downtown and the place of execution seem to eventually head to the world of sunya. In the world of sunya, the character "I" choose its death as the Mind of sunya. Park Sang-ryung``s 『A Study on Death』 is a novel that well-embodies the change of Mind that the character "I" travel through.

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".

DEA를 이용한 여성복지서비스의 효율성 평가: 여성인력개발센터를 중심으로

성도경 ( Do Kyung Sung ),최인규 ( In Kyu Choi ) 대한정치학회 2009 大韓政治學會報 Vol.16 No.3

오늘날 여성경제활동에 대한 사회 정책적 관심이 증가하면서, 여성의 노동권 보장을 위한 다양한 복지정책지원에 주목하기 시작하였다. 이 시점에서 여성인력개발센터는 그간 여성의 능력개발 및 여성복지서비스에 대한 시대적 변화에 적극 대처함으로써 여성의 경제활동과 참여 증대에 기여해 온 점은 부인할 수 없는 사실이다. 그러나 최근 센터별 운영적인 측면과 서비스에 대한 효율적인 측면에서 여러 가지 문제점이 나타나고 있는 실정이다. 이러한 측면에서 본 연구는 DEA(Data Envelopment Analysis), FDH(Free Disposal Hull), 기법을 이용하여 각 여성인력개발센터의 효율성을 실증적으로 비교·분석하였다. 본 연구의 분석지표로는 투입변수에 프로그램 개설수, 직원 수, 정부지원보조금율, 산출변수에 수료자 수, 취업자 수, 상담실적을 사용하였다. 분석결과 CCR모형의 효율성평가에서는 강북, 광진, 구로, 동대문, 인천, 울산, 성남, 강릉, 천안 등 9곳이 효율적인 센터로 나타났다. BCC분석에서는 21개 센터가 효율적인 센터로 나타났다. 또한 슬랙(slacks)값이 20%이상이 되는 각 기관들의 투입변수와 산출변수의 변화를 통해 효율성을 증가시킬 수 있는 방향을 살펴보았는데, 여성복지서비스의 개선을 위한 여성인력개발센터의 효율적 운영을 위해서는 교육프로그램의 질적 내실화, 인력의 충분성과 전문성 확보, 지방자치단체의 지원금의 재조정이 필요한 것으로 나타났다. As the increase of politic concern over the economic activity of women, it began to attract the need of various welfare policies to secure the woman`s labor right. In this respect, Woman Resources Development Center has contributed to the increase of women`s economic activities and participation. But, it shows a lot problems in the respect of operations and services. Therefore, this study empirically analyzed the efficacy of countrywide Woman Resources Development Centers using DEA(Data Envelopment Analysis) and FDH(Free Disposal Hull) methods. The number of programs, the number of employees, and subsidy from government were used as input variables, and the number completed the program, the number of employed worker, and results of consultation were used as output variables. The evaluation of efficacy by CCR model showed nine centers, such as Kang-book, Kwang-jin, Koo-ro, Dong-daemoon, Incheon, Ulsan, Sung-nam, Kang- reung, and Chun-an were efficient. The evaluation of efficacy by BCC model showed 21 centers were efficient. This study proposed that it needs qualitative improvement of education programs, secure of sufficiency and professionalization of woman power, resettlement of subsidy from local governments to improve the operation of Woman Resources Development Center.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

This study was conducted in order to explore general flora of the Gyounggi-do Province and to clarify the distribution of some specificated taxa of the Korea. Daebu-do Island, Mt. Taewha, Mt. Hwaya, Mt. Gumdan, Mt. Chilhyun and Mt. Chulma among eighth grade-area of the Degree of Green Naturality (DGN) within the boundary of the Gyounggi-do Province were visited to investigate local flora. The number of identified vascular plant species were as follow; Mt. Hwaya: 120 species (99 genera of 67 families), Mt. Teawha: 132 species (103 genera of 56 families), Daebu-do Island: 124 species (103 genera of 50 families), Mt. Chulma: 129 species (99 genera of 67 families), Mt. Gumdan: 121 species (96 genera of 52 families), Mt. Chilyun: 90 species (74 genera of 42 families). The endemic Clematis brachyura Maxim. was found to distribute Daeby-do. It seemed that plantation was occupying large area in forest of the Gyounggi-do Province. Forty two specificated taxa were identified and 3 taxa, 10 taxa, 5 taxa, and 24 taxa were sorted into forth grade, third grade, second grade, and first grade respectively. Mt. Taewha showed the highest record (16 taxa) in the number of specificated taxa, Mt. Hwaya was the next with 13 taxa. Mt, Chulma (12 taxa), Mt. Gumdan (11 taxa), Daebu-do Island (7 taxi), and Mt, Chylma (4 taxi) followed. Mt. Taewa and Mt. Whaya were found to be relatively higher in the score calculated front the specificated taxa distribution, while Daebu-do Island and Mt. Chilyun were lower, that difference was probably due in part to consequences of severe disturbance of human activities. With respect to the consequences of severe disturbance of human activities. With respect to the geographical proximity to the Gangwon Province, Mt. Hwaya showed higher similarity of the species composition to that of the Mt. Jumbong.

The purpose of this research is to provide basic data suggesting the direction of disabled taekwondo player's healthy leisure activity through the analysis on actual status of disabled taekwondo players' leisure activity. The subject was 41 maleㆍfemale players participating in the 32th national athlete meet for the disabled. Data of this research was analyzed by SPSS WIN 18.0 program. For the concrete statistical method, frequency analysis and cross analysis were done so as to examine general characteristics of research subject and differences of awareness on leisure activity. To examine interests in leisure activity and differences of satisfaction, t-test and one-way Anova were conducted. And, a positive analysis was verified in significance standard p<.05, p<.01, p<.001. As a result of Scheffe method as a post-hoc test, following conclusions were obtained. First, interests in leisure activity were higher as the time of participation in contest was higher and they learned taekwondo because they want to do. For the motives of participation in leisure activity, main factors were pleasure of life, relief of stress and emotional stability. Satisfaction for leisure activity was generally more than medium level, 3 scores. What are the most necessary for leisure activity were leisure of time, money(costs), friends to enjoy together and facility/location. Obstacles of leisure activity were insufficient money(costs), insufficient time, insufficient location/facility, so they had an awareness similar to the necessary of leisure activity. Therefore, players who have lots of times to participate in taekwondo contest and learned taekwondo because they wanted to do can be the group with active tendency. And, active group showed high demands of interests and satisfaction in leisure activity. Second, costs of monthly leisure activity were increased as current grade was higher and the number of participation in contest was more. Daily taekwondo training time was longer as they were women and the number of participation in contest was more. Daily leisure time of weekdays was longer as the number of participation in contest was more. Leisure time of weekends and holidays was less than 4 hours in more than half players. For the location of leisure activity, male players preferred leisure sports center and internet cafe and female players preferred leisure sports center and shopping/department store. Especially, group with lot of times of participation in contest showed long training time, much leisure activity time and high activity costs. It means disabled taekwondo players participating in many times showed long activity time of taekwondo, but participated in various leisure activities. Third, for the form of leisure activity, they mainly preferred rest/sleeping and leisure sports. For the favorite sports as leisure activities, male players preferred soccer, basketball and swimming and female players preferred soccer, inline skating and balling. For the people they enjoy leisure activity together, there were friends, colleagues and alone in may cases. Therefore, there were various activities preferred by gender. Fourth, for the activation measures of leisure activity, there were leisure of time, facility/location and cultivation of professional instructor in order. Therefore, leisure of time was insufficient as a factor which is the most necessary for leisure activity and hinders leisure activity. So, activity program which can be approached easily around us on weekdays and holidays should be developed.

1993년부터 2015년까지 관측된 제주도 지하수 장기모니터링 관측정(N = 4,835)에서 수집된 지하수 수질자료(N = 21,568)를 기반으로 질산성질소의 시공간적 변동 특성을 평가하였다. 제주도 지하수의 질산성질소 농도의 중앙값은 2.5 mg/L로서 다른 국가나 대륙의 조사 결과에 비해 다소 높거나 유사한 것으로 나타났다. 또한 지하수 용도, 행정구역 및 고도 별로 유의한 차이를 보였다. 특히, 산간 지역에 비해 저지대 해안가에 위치한 농업 및 주거지역에서 농도가 높음을 확인하였다. Mann-Kendall 및 Sen’s slope 분석을 활용한 질산성질소 농도의 추세 분석 결과, 하류 저지 대에 비해 중산간지역에서의 질산성질소 농도 증가 경향이 뚜렷하였다. 제주도 내 토지 피복의 시계열 변화 특성과 결부 지어 보면, 중산간지역의 오염 증가 추세는 농업지역의 확장 등 인위적 활동 증가에 기인한 결과로 판단된다. 반면,기지정된 지하수자원특별관리구역에서는 전반적으로 질산성질소 농도의 감소 경향이 나타났는데, 이는 지하수 관리 측면에서 수질관리를 위한 적극적인 정책이 유효함을 시사한다. 본 연구에서는 제주도 지하수의 질산성질소 오염관리를 위한 적정 방안을 제안한다. The spatio-temporal variations of nitrate concentrations in groundwater of Jeju Island were evaluated by an analysis of time series groundwater quality data (N = 21,568) that were collected from regional groundwater monitoring (number of wells = 4,835) for up to 20 years between 1993 and 2015. The median concentration of NO 3 -N is 2.5 mg/L, which is slightly higher than those reported from regional surveys in other countries. Nitrate concentrations of groundwater in wells tend to significantly vary according to different water usage (of the well), administrative districts, and topographic elevations: nitrate level is higher in low-lying agricultural and residential areas than those in high mountainous areas. The Mann-Kendall trend test and Sen’s slope analysis show that nitrate concentration in mid-mountainous areas tends to increase, possibly due to the expansion of agricultural areas toward highland. On the other hand, nitrate concentrations in the Specially Designated Groundwater Quality Protection Zones show the temporally decreasing trend, which implies the efficiency of groundwater management actions in Jeju. Proper measures for sustainable groundwater quality management are suggested in this study.
