한수곤,최정식,문영훈,엄미정,김갑철 한국환경농학회 2000 한국환경농학회지 Vol.19 No.2

동진강 수계의 수질현황을 파악하기 1994∼1998년 까지 4∼9월에 월 1회에 걸쳐 5개년간 조사한 결과를 요약하면 다음과 같다. 월별로는 빗물에 의한 희석효과로 7, 8월에 수질이 가장 양호하였으며, 4월이 다소 불량하였으나 수도생육 피해 한계농도에는 미치지 못하는 수준이었다. 지점별 수질현황은 생활하수 유입지인 정읍천과 지천의 폭이 좁은 원평천의 무기성분 함량이 높았으며 동진천 상류지역에서 가장 양호하였다. 연도별 현황은 '94년 이후 '95년까지는 수질이 악화되는 경향을 보였으나 '95년 이후로는 각 성분 함량이 낮았지는 등 점점 양호해지고 있으며 COD함량으로 볼 때 특히, 정읍천의 수질이 개선되고 있음을 알 수 있었다. 양이온과 음이온의 총당량온 4월에 가장 높았고 7, 8월에 가장 낮았으며 양이온/음이온의 당량비는 5월에 높았고 7월이 가장 낮았으며 지점에 따라서는 총당량은 정읍천, 원평천, 동진천 하류, 중류, 상류의 순위였으며 양이온/음이온 총당량 비율은 원평천이 상대적으로 작은 수치를 보였지만 지역간 큰 차이는 보이지 않았다. 수질 중 각 성분 상호간의 상관관계를 보면, 대개의 성분 상호간에 유의성이 높게 나타났으나, NO₄^--N는 대개의 성분과 유의성이 없었고, PO₄^(3-)-P도 COD, NH₄^+-N, NO₃^--N, SO₄^(2-)과는 유의성을 보이지 않았다. This study was conducted to monitor the irrigation water qualities along Dong-Jin river watershed. The water quality was surveyed at 6 sites from April to september during 1994∼1998. And the results were as follows : In July and August, water quality was better than that of any other months due to dilution with rainwater. Whereas, it became worse in April but it involved lower contents than limitted contents affected to the crop damage. Content of inorganic components was higher at Jeong-up and Won-pyeong stream. The reason for it that Jeong-up stream was deteriorated with sewage water from Jeong-up city, and Won-pyeong stream has narrow width. Water quality in upstream of Dong-Jin river, was evaluated best conditions in all sampling sites. For investigated period, water quality got worse from 1994 to 1995 but it was getting better to 1998 after 1995, especially at Jeong-up stream. The total equivalent of cation and anion was the highest at April through all months and at Jeong-up stream in sampling sites. Equivalent ratio of cation to anions(∑C/∑A) was higher at May than any other months and lower at Won-pyeong streams than any other sites. The value of most inorganic components was highly correlated with those of other components. But the value of NO₃^--N was not correlated with that of most components, and PO₄^(3-)-P was not correlated with COD, NH₄^+-N, NO₃^--N, SO₄^(2-_.

An Experimental Study on Interrelation of Influential Parameters on Unbonded Tendon Stress

Moon, Jeong-Ho,Lim, Jae-Hyung Korea Concrete Institute 2006 International Journal of Concrete Structures and M Vol.18 No.e2

The purpose of this study is to investigate the relations between unbonded tendon stress and its influential parameters, i.e. bonded reinforcement ratio, span/depth ratio, and loading type. To this end, the influence of such parameters was examined with twenty eight test results of previous studies. Afterwards, an experimental study was carried out with twenty one test specimens. The investigation of previous and current experiments revealed the followings; (1) The bonded reinforcement ratio and prestressing ratio were proved to be important variables on the unbonded tendon stress. (2) The ratio of span to depth and the type of loading affected the unbonded tendon stress partially although their effects varied with bonded reinforcement ratio. (3) AASHTO LRFD Code and Moon/Lim's design equations predicted the experimental results well with the safety margin.

Background: Recently, The number of patients who have been complaining of the vertigo or dizziness has been increasing due to rapid growth of elderly population and senile disease. The differentiation of dizzy patients is not familiar to most emergency physicians. This study was designed to differentiate true vertigo and to investigate the clinical difference among central vertigo, peripheral vertigo, and other causes of dizziness. Methods: The authors analyzed the cases of 237 dizzy patients who visited the emergency department of Chonnam University Hospital during the recent 2 years. For the base of dizziness, associated past illnesses, severity, nystagmus type, and the causes of central and peripheral vertigo. Results: Female patients were 142(59.9%) and male patients were 95(40.1%). The most common age group was the 6th decade. The origin of dizziness was classified as peripheral cause(25.3%), central cause(32.9%), and others(41.8%). As to nature of the dizziness, the rotatory sense was dominant in peripheral vertigo and the floating sense and blurred vision in central vertigo. Peripheral vertigo was triggered by position change of head and body, and central vertigo by the eye movement. Audiograms I showed that most patients with central vertigo had normal hearing, but 46.7% of thoswith peripheral vertigo had an abnormal hearing disturbance. Nystagmus was more prevalent in peripheral vertigo Conclusion: History taking and physical examination played an important role in the diagnosis of dizzy patients. An important part of the diagnosis of a dizzy patient could be to evaluate the peripheral origin, the central origin and others causes. Because central vertigo may be associated with a significant neurological pathology, spectral radiological studies, including MRI and CT, are mandatory to rule out a devastating brain lesion.

Moon, Jeong-Ho,Shin, Kyung-Jae,Lim, Jae-Hyung,Lee, Sun-Hwa Korea Concrete Institute 2000 KCI concrete journal Vol.12 No.1

The research purpose of this paper is to investigate the influential Parameters on the unbonded tendon stress. The parameters were the reinforcing ratio, the prestressing ratio, and the loading type. To this end. first, the influence of parameters were examined with twenty eight test results obtained from references. Then, an experimental study was carried out with nine specimens. Test variables were the reinforcing ratio and the prestressing ratio. Specimens were divided equally into three groups and each group had a different level of the reinforcing ratio. Each specimen within a group has a different level of the prestressing ratio. The investigation with previous and current tests revealed the followings; (1) the length of crack distribution zone does not have a close relation with the length of plastic hinge. (2) the prestressing ratio does not affect both the length of crack distribution and the length of plastic hinge, (3) the tendon stress variation is in reverse relation with the ratios of mild steels and tendons, (4) the loading type nay not affect significantly the length of crack distribution zone, (5) AASHTO LRFD Code equation and Moon/Lim's design equation predicted the test results well with some safety margins.

Voice Mismatch Meets Neurolinguistics

Gui-Sun Moon, Sun-Woong Kim, Jeong-Ah Shin, Hae-Kyung Wee, Jong Un Park, Myung-Kwan Park, and Wonil Chung. 2018. Voice Mismatch Meets Neurolinguistics. Studies in Modern Grammar 99, 85-115. This paper aims to investigate Korean advanced L2 English learners’ strategies for ellipsis resolution during sentence processing. Ellipsis resolution is known to involve several stages of information processing from the initial step of detecting an ellipsis-licensing element by the parser to the final stage of integrating the ellipsis site with the information retrieved from the antecedent of the ellipsis site. In examining these steps, we have manipulated three factors: (i) TP vs. VP-ellipsis; (ii) two types of discourse coherence relations (resemblance(-contrast) vs. cause-effect relations); (iii) voice match vs. mismatch. We found through the ERP recordings that voice mismatch in TP ellipsis elicited N400, followed by P600, irrespective of discourse coherence relations. In contrast, voice mismatch in VP-ellipsis registered N400 only in resemblance(-contrast) relation, but not in cause-effect relation. These findings lead us to conclude that Korean advanced L2 learners of English seem to undergo the full sequence of processing stages required for ellipsis resolution.

韓龍雲 詩에 나타난 逆說과 慈悲意識 硏究

文丁姬(Moon Jeong-hee) 우리문학회 2008 우리文學硏究 Vol.0 No.24

만해의 시적 욕망은 역설이란 하나의 대립적 관계 속에서 의미화 한다. 만해의 시 「님의 침묵」, 「거짓 이별」 등에서 잘 드러나 있듯, 한용운의 시세계는 단순한 시적 상상력에서 벗어나 유와 무, 이별과 만남이 서로 균형을 이루며 시적 체험을 극대화시켜 나가고 있음을 보게 된다. 이는 단순하게 언어 탄력감을 확보하기 위한 기법이 아닌, 자비의 기틀을 마련하기 위한 방법으로 시인의 정신의 깊이를 일깨우는 긍정적 힘으로 작용한다. 그의 시에서 눈물이 쏟아질 때 ‘당신 얼굴’이 보이고, ‘님’에 대한 격분으로 슬픔이 고조되는 찰나 ‘당신의 환영’이 표출되는 시적 경험은 자비의 국면에서 이루어지고 있다는 의미와 맥을 같이한다. 그래서 만해시의 역설적 체험은 주체의 정서와 사유가 결합될 수 없는 부조화의 관계이면서도 시 전체를 대립적 관계로 몰아넣지 않고 스스로 자비의 세계에 진입하는 논리 구조로 전달이 된다. 이때 주체의 시적 상상력은 역설적 의미의 폭을 지니고 나타남은 물론이다. 그 이유는 生, 死, 善, 惡의 관계없이 인간의 삶은 자비의 세계에서 깨달음을 추구해야 한다는 불교사상과 맥을 같이 한다. 자비의 세계는 고통도 갈등도, 오르고 내림도 없는 평등의 세계에서 출발하기 때문에 온 우주의 사물은 동일한 존재로 드러나고 있는 것이다. 그러나 주시할 것은 그러한 만해의 긍정적인 자비의 작용이 서정주, 조지훈 등의 불교시인들과는 현저한 차이를 드러내고 있다는 점이다. 조지훈의 경우는 자신의 내면 풍경을 역설의 관점에 중점을 두기 보다는 자연의 질서와 조화를 표현하는 전통적 자연회귀의 세계에 더 관심을 기울였던 점을 감안하면, 만해의 역설은 갈등의 세계를 해체시키고 고귀한 자비의 창조적 변용을 불러들이는 覺者의 모습을 드러내고 있는 것이다. 이 같은 만해의 시적 사유를 한편으로는 과도한 불교의식의 내면 표출이라는 지적도 있지만, 있음과 없음의 모순되는 이미지들을 통하여 자비의 역설을 끌어낸 시적 변용을 보면 그러한 의문은 쉽게 풀리게 된다. 즉 그의 시에서 표출되는 ‘불만족. ‘찬 이슬’ 등 모순적 언어의 정서는 어둠의 세계를 전달하는 극단의 대상이지만, 그러한 어둠의 내적 체험도 역설의 범주로 전위될 경우는 자비의 풍요로움을 불러들이는 긍정의 경험을 하게 되는 것이다. 이는 고통, 탐욕, 증오 등 세속적 갈등에서 벗어나 진정한 자비의 변화를 추구하는 만해의 시적 정신으로 만해의 자비의식을 이해하지 않을 수 없게 하는 중요한 요인이 된다. MANHAE's poetic desire is represented in an antagonistic relationship of a paradox. As well revealed in his poems, 「Nim's Silence」, 「False Parting, and etc, HAN YONG-UN's poetic world does not lie simply in poetic imagination but it is shown in maximum extended poetic experiences where existence and nonexistence, parting and meeting form a balance to each other. This is not just a technique to seek for resilience of words but to prepare the frame of mercy which gives a positive force to remind us of deep insights of the poet. The poetic experiences shown in his poem, namely that 'your face' is seen when tears are flowing down and 'your phantom' is represented on the moment when sorrow reaches its peak due to the fury toward 'Nim' are in the same meaning that those experiences are originally made in the context of mercy. Therefore, the experience of paradox and mercy this manuscript is trying to suggest is delivered in the logical framework that such experience itself enters into the world of mercy though the main emotion and thinking of the subject can not be combined together in the relationship of disharmony. Of course, at this moment the subject's poetic imagination appears in the form of paradoxical meaning. The reason is that it is in the same viewpoint of Buddhism believing that human life is to seek for spiritual enlightenment in the world of mercy. Since the world of mercy starts from the world of equality in which there are no pains or conflicts and no uphills or downhills in life, each and every thing in the universe is to be revealed as the identical existence. However, it is one thing to be noted that such a positive force in MANHAE's poems reveals a remarkable difference as compared with other Buddhist poets such as SUH JEONG-JU, JO JI-HOON, etc. JO JI-HOON showed more emphasis on the traditional returning-to-nature world in which the order and harmony of nature are expressed rather than emphasis on the paradoxical view of his deep insights, whereas MANHAE's paradox reveals that it disintegrates the world of conflicts aiming to bring in the creative metamorphosis of his sublime mercy, which forms another aspect of a man with foresight. Someone would point out that this kind of MANHAE's poetic cogitation is an excessive representation of a Buddhist's innermost consciousness, but such doubt could be well clarified if we look at his poetic metamorphosis which elicited the paradox of mercy through conflicting images of existence and non-existence. In other words, though his contradictory words of emotions expressed in his poems become an object of extremities to depict his world of darkness, such inner experiences in darkness could bring forth the positive force calling in the affluent mercy if it should be transposed into the range of a paradox. This would surely constitute an important factor in driving us to recognize and understand the poetic spirit of MANHAE since it is seeking for a change into a true mercy leaving them out of secular conflicts, such as suffering, greed and hatred, etc.

조인호,정대훈,박영미,서영진,손영실,정철회,강영미,정수전,김영남,이경복,성문수,김기태 인제대학교 2006 仁濟醫學 Vol.27 No.-

Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

Background: Although cardiopulmonary resuscitation(CPR) is a very effective therapy in cardiac arrest, it is hard to prove the true effectiveness of CPR. Several studies about out-of-hospital and emergency department CPR exist, but only a few reports about in-hospital CPR are available. This study was designed to investigate in-hospital cardiac arrest, to analyze the result of CPR, and to evaluate the problems associated with in-hospital CPR. Methods: A clinical analysis of 71 cases of in-hospital CPR announcement from January 2000 to August 2000 was performed. The initial rhythm on cardiac arrest, return of spontaneous circulation(ROSC), and the survivals were analyzed in the case of the 46 true cardiac arrest patients. Results: During 8 months, there were 71 cases of in-hospital CPR announcement. Among them, there were 46 cases of true cardiac arrest and 25 cases of non-cardiac arrest. Of the 46 true cardiac-arrest cases, 27(58.7%) experienced ROSC, 15(32.6) survived for over 24 hours, and 7(15.2%) survived to be discharged. The initial rhythms on cardiac arrest were 30 cases(65.2%) of asystole, 14(30.4%) of PEA(pulseless electrical activity), and 2(4.3%) of ventricular fibrillation, with ROSC being 17 cases(56.7%), 9(64.3%) and 1(50.0%) cases and discharged survivors being 4 cases(13.3%), 3(21.4%) and 0(0.0%) cases, respectively. Conclusion: Extraordinarily high proportions of asystole and PEA were seen in the initial rhythm of cardiac arrest, and those were associated with high survival rates. Although further study is needed to evaluate the course leading to this high proportion of asystole and PEA, this result suggests that if the EMS system in the hospital is activated promptly and systematically, a better outcome will be achieved in case of cardiac arrest with asystole and PEA.

정수장슬러지의 고형물량에 대한 예상치의 비교

문용택,김정현 대한상하수도학회 2003 상하수도학회지 Vol.17 No.1

The quantity of residuals generated from water treatment plants depends upon the raw water quality, dosage of chemicals used, performance of the treatment process, method of sludge removal, efficiency of sedimentation, and backwashing frequency. Sludge production by the physical separation of SS occurs under quiescent conditions in the primary clarifier, where suspended solids are allowed to settle and to consolidate on the clarifier bottom. Raw primary sludge results when the settled solids are hydraulically removed from the tank. The relative solid and liquid fractions of a slurry are most commonly described by the solids concentration, expressed as ㎎/L or percent solids. The purpose of the present investigation is to correlate predicted value with practical value on the quantity of alum coagulant sludge.
