정경진,천영신,하수현,강현경,윤재길 한국원예학회 2012 원예과학기술지 Vol.30 No.1

To elucidate the role of silicon in biotic stress such as pests and diseases, standard chrysanthemum was grown in pots filled with soil without application of pesticide and fungicide. Si treatment was largely composed of three groups: K2SiO3 (50, 100, and 200 mg・L-1), three brands of silicate fertilizer (SiF1, SiF2,and SiF3) and tap water as a control. Si sources were constantly drenched into pots for 14 weeks. Application high concentration K2SiO3 (200 mg・L-1) and three commercial Si fertilizers for 14 weeks improved growth parameters such as plant height and the number of leaves. In the assessment of disease after 4 weeks of Si treatment, percentage of infected leaves was not significantly different from that of control. After 14 weeks of Si treatment, however, the infected leaves were significantly reduced with a 20-50% decrease in high concentration (200 mg・L-1) of potassium silicate and all commercial silicate fertilizers. Colonies of aphid insect (Macrosiphoniellas anborni) were also reduced in Si-treated chrysanthemum, showing 40-57% lower than those of control plants. Accumulation of silicon (approximately 5.4-7.1 mg・g-1 dry weight) in shoots of the plants was higher in Si-supplemented chrysanthemum compared to control plants (3.3 mg・g-1 dry weight). These results indicate that using potassium silicate or silicate fertilizer may be a useful for management of disease and aphid insect in soil-cultivated chrysanthemum.

일본 문인화의 선구자 기온 난카이(祇園南海)의 시론 - 『시가쿠호겐(詩学逢原)』(1763)를 중심으로 -

정경진 한양대학교 일본학국제비교연구소 2021 비교일본학 Vol.51 No.-

본고는 일본 문인화의 선구자로 평가받는 유학자 기온 난카이(祇園南海,1676 1751)를 중심으로 그의 문인화 활동이 유학 습득의 과정에서 나타난 詩作의 중시로부터 시작되었음에 주목하고자 한다. 구체적으로는 1763년에 간행된 난카이의 시론서 『詩学逢原』의 분석을 통 해 문인화의 중요 요소인 ‘시화(詩画)일치’의 실현 배경에 그의 시론이 큰 영향을 주었음을 논하고자 한다. 난카이가 활동한 18세기 초 근세 일본의 지식인 사회에서는 철저하게 일상의 것, 세속적인 것을 나타내는 俗의 요소를 배제하고 고문을 모방하면서 雅를 터득하는 것이 지식인의 지적활동의 중심이었다고 할 수 있다. 『詩学逢原』전체를 통틀어 난카이 시론의 핵심은 ‘影写’와 ‘雅俗’이라 할 수 있다. ‘影写’란 글이나 그림 위에 얇게 비치는 종이를 덧대어 원본의 형태가 드러나게 하는 것을 말하는데 시를 음미하면서 시어가 비추어내는 이미지가 마치 눈 앞에 펼쳐지는 것 같은 입체적인 현장감을 유도한다. ‘影写’의 실현을 위해 난카이는 詩語와 常語의 구분, 시문의 일부를 취하여 사용하는 断章取義를 강조하고 있다. 한편 그는 ‘시는 풍아를 담는 그릇’이라고 표현하며 ‘사물에 빗대어 자신의 정감을 표현하는 것이 바로 雅라고 정의하며 雅는 일상 생활에서 쉽게 사용되지 않는 엄격하고 심오함을 추구하는 것이 고 俗은 누가 들어도 그 정취를 쉽게 이해할 수 있는 평이한 말로 보았다. 또한 이를 실현하 기 위해 시에 있어 경중, 청탁, 대소, 완급, 강약의 조화를 강조하였다. 난카이는 이것을 ‘시의 가장 중요한 근본’이라고 보았는데 시뿐 아니라 회화관에 있어서도 이러한 시론이 그대로 적 용하고 있다는 사실은 매우 흥미롭다 할 수 있다. This paper focuses on Confucian Nankai Gion (1676-1751), a Confucian scholar who is evaluated as a pioneer of Japanese literary painting, to note that his literary work began with the emphasis on literary works that appeared in the process of learning abroad. Specifically, through the analysis of Nankai's poetic book 『詩学逢原』 published in 1763, I would like to discuss that his poetic theory had a great influence on the background of the realization of the important element of literary painting. . In the early modern Japanese intellectual society in the early 18th century in which Nankai was active, it can be said that the core of intellectual activities of intellectuals was to thoroughly exclude the elements of worldlines that represent everyday things and secular things, and imitate torture and learn elegant. Throughout the entire 『詩学逢原』, the core of Nankai's poetry can be called ‘Shadow(影写)’ and ‘classical and colloquial(雅俗)’. ‘Shadow’ refers to the appearance of the original form by adding a thin piece of paper on top of a text or picture, and while appreciating the poem, it induces a three-dimensional sense of reality as if the image reflected by the poem unfolds before your eyes. Nankai emphasizes the distinction between poetic language(詩語) and common language(常語), and 斷章取義, which takes part of a poem and uses it for the realization of ‘Shadow’. On the other hand, he expresses that “poetry is a container that holds good spirits” and defines it as elegant that expresses one's feelings in relation to things, and elegant is a pursuit of strict and profoundness that is not easily used in everyday life. I saw the mood in plain language that was easy to understand. In order to realize this, he also emphasized the harmony of lightness, solicitation, greatness and smallness, gentleness, and strength in poetry. Nankai saw this as “the most important foundation of poetry,” but it is interesting to note that this poetic theory is applied as it is not only in poetry but also in the view of painting.

정경진,손병화 대한치과교정학회 1995 대한치과교정학회지 Vol.25 No.3

두개악안면 영역은 많은 해부학적 구조를 포함하는 근골격구조(musculodentos keletal system)로 두부골격의 구조, 악궁상태, 저작근의 형성 및 기능은 서로 밀접한 연관성을 가지고 있다. 두개악안면 영역의 성장과 발육은 유전적인 요인이외에 환경적인 요인들 즉, 두개안면부의 근육을 포함한 주위조직의 영향을 받는 것으로 이미 알려져 있다. 그러나 반대로 두개안면부의 골격구조가 변화되는 경우 이에 대응하여 두개안면근육의 기능 또한 변화, 적응되는지에 대해서는 체게적인 연구결과가 미흡한 상태이다. 저자는 골격형 제 Ⅲ급 부정교합자의 악교정수술 전, 후의 근활성도의 변화에 대한 비교연구를 통해 두부 골격구조와 교합상태에 따른 저작근 기능의 상호관계 및 변화 양상에 대해 알아보고자 정상교합을 가진 성인남자 15명과 술전 및 술후 골격형 제 Ⅲ급 부정교합자 각각 15명을 대상으로 측모두부 방사선사진과 저작효율검사 및 rest, clenching, chewing, swallowing시의 전측두근, 교근, 상순의 근활성도 검사를 시행하여 다음과 같은 결과를 얻었다. 1. 하악의 안정위(rest)에서 술전 부정교합군에서 술후군보다 전측두군, 교근, 상순에서 높은 활성도를 보였으며, 술후군에서는 상순에서만 정상대조군보다 의미있는 높은 근활성도를 보였다. 2. 최대교합(clenching)시는 술후군에서 술전 부정교합보다 전측두근, 교근, 상순에서 높은 근활성도를 보였다. 3. 저작(chewing)시는 술후군이 술전 부정교합군보다 전측두근 및 교근에서 높은 활성을 보인 반면 상순에서는 감소된 근활성도를 보였다. 4. 연하(swallowing)시 술후군에서 상순은 술전 부정교합군보다 감소되었으나 정상대조군보다 증가된 근활성도를 나타냈으며, 각 군간에 전측두근 및 교근에서는 유의차가 없었다. 5. 저작효율은 술전부정교합군에서 정상대조군보다 낮았으며, 술후군에서 술전 부정교합군보다 증가되었으나 두군 모두 정상대조군과 유의차를 보였다. Craniofacial region is a musculodentoskeletal system that consists of many anatomical structures ; cranioskeletal structures, dental arches, and formation and functions of masticatory muscles have close correlations. Growth and development of craniofacial region are influenced by not only hereditory factors, but also environmental factors such as craniofacial muscles and surrounding tissues. On the contrary, however, study on changes in functions or adaptations of craniofacial muscles following changes of craniofacial skeletal structures has been somewhat insufficient. The author's purpose was to observe correlations between masticatory muscular functions and change patters according to cranial skeletal structures and occlusion patters ; for this, comparative study of muscle activity changes of preand post-orthognathic surgery states in skeletal Cl Ⅲ malocclusion patients was performed. The selected sample groups were 15 normal male patients, 15 skeletal Cl Ⅲ pre-orthognatic surgery patients and 15 skeletal Cl Ⅲ post-orthognatic surgery patients. For each sample groups, cephalometric x-ray taking, masticatory efficiency test and measurements of muacle activities in anterior temporal muscle, masseter and upper lip in rest, clenching, chewing and swallowing were carried out. The following results were obtained : 1. In resting state of mandible, pre-surgery malocclusion group showed higher m. activities in ant. temporalis, masseter and upper lip than post-surgery group. Post-surg. malocc. group showed significantly high m. activity only in upper lip compared to the normal group. 2. In clenching state, post-surg. malocc. group showed higher m. activities in ant. temporalis, masseter and upper lip than pre-surg. malocc. group. 3. In chewing state, post-surg. malocc. group showed higher m. activities in ant. temporalis and masseter than pre-surg. malocc. group ; on the other hand, decreased upper lip activity was noticed. 4. In swallowing state, post-surg. malocc. group showed lower upper lip activity than pre-surg. malocc. group but higher than that of the normal group. No significant difference in m. activities of ant. temporalis and masseter was noticed among the three groups. 5. Masticatory efficiency was lower in pre-surg. malocc. group than normal group ; masticatory efficiency showed and increase in post-surg. malocc. group compared to the pre-surg. malocc. group. However, both groups showed significant differences compared to the normal group.

The point of time in a high science development and today's change gone quickly, people have been going to live with nature. Landscape architecture isn't the way seeing a building as an object while nature is a background, but also the way making them positive relation by destroying their boundary. This destroyed boundary doesn't stop being shown only at the outside. It destroys a boundary among the bottom, column and roof in inside a building. At this destroying boundary process, topology concept can be used. Topology is the branch of mathematics that studies the properties of a space that are preserved under continuous deformations. A museum will be formed by folding in topology. Topology will make the space continuous. Topology and landscape architecture concept will be used at Chung-nam national university nature history museum.

Purpose: Botulinum toxin(BTX) acts by inhibiting acetylcholine(ACh) release at the presynaptic cholinergic neuromuscular junction, and is applied in various urethral and bladder dysfunctions, including detrusor external sphincter dyssynergia(DESD). We investigated the use of BTX in DESD patients as a reversible chemical sphincterotomy. Materials and Methods: A total of 6 patients(male 3, female 3) with DESD were included. Their mean age was 45.5 years. The underlying diseases were multiple sclerosis(1), meningomyelocele(1), spinal cord injury(1), multiple systemic atrophy(1) and transverse myelitis(2). All the patients had severe voiding symptoms and large residual urine, despite anticholinergics and α-adrenoceptor antagonists with clean intermittent catheterization(CIC). Urodynamic studies were performed before and 1 month after treatment. A total of 100 units of BTX-A(BotoxⓇ) were injected at 4 sites, 3, 6, 9 and 12 o'clock relative to the external sphincter, under anesthesia, on an outpatient basis. The α-adrenoceptor antagonist medication was discontinued for evaluation after surgery. Results: At 1 month after the injection, the mean maximal flow rate was increased(from 8.4 to 12.2ml/sec) and mean residual urine was decreased (from 258 to 120ml) compared to the baseline values. The external sphincter pressure was decreased. All patients were able to discontinue the CIC. There were no systemic complications, such as respiratory distress or myasthenic crisis. Conclusions: Transurethral BTX-A injections were safe and effective for releasing or ameliorating a lower urinary tract obstruction due to DESD, and a safe and valuable therapeutic option in DESD patients not desiring surgery or CIC, and who are resistant to medications.

인공신경망을 이용한 유역 내 침수피해 예측모형의 개발

정경진,Chung,Kyung-Jin,Chen,Huaiqun,Kim,Albert S 한국방재학회 2005 한국방재학회논문집 Vol.5 No.2

본 논문에서는 유역 내 침수피해를 예측할 수 있는 실현가능한 수단으로써 인공신경망의 활용에 대해 제안하고자 한다. 유역 내 다양한 환경인자에 의한 침수피해 예측모형의 구축을 위해 108개 중유역을 대상으로 1990년부터 2000년까지 강우량, 침수피해면적, 토지이용 등 총 27개의 매개변수를 선정하여 총 49개의 데이터 세트를 구성하였다. 연구결과, 침수피해는 강우량과 같은 기상정보 뿐 만 아니라 다양한 유역환경의 특성에 영향을 받는 것으로 나타났으며 인공신경망 모형에 의해 R=0.92 수준에서 예측값과 관측값이 잘 일치하는 것으로 나타났다. 따라서 인공신경망은 입력값들과 대응된 출력값들을 알고 있는 경우 과거와 현재의 시공간 정보를 활용하여 특정유역의 강우량에 따른 침수피해면적을 산정 할 수 있으며, 복잡하고 비선형적 역동성을 지니고 있는 유역 내 환경변화에 대한 예측모형으로 활용이 가능하다고 판단된다. 또한 인공신경망은 입력자료의 중요도를 평가하는데 이용될 수 있으며, 기존 모형에서 다루어지는 매개변수중요도를 정량화 시킬 수 있어 다른 모형의 매개변수 추정이나 보정에 도움을 줄 수 있을 것으로 판단된다. This paper presents the use of an Artificial Neural Network (ANN) as a viable means of forecasting Inundation Damage Area (IDA) in many watersheds. In order to develop the forecasting model with various environmental factors, we selected 108 watershed areas in South Korea and collected 49 damage data sets from 1990 to 2000, of which each set is composed of 27 parameters including the IDA, rainfall amount, and land use. After successful training processes of the ANN, a good agreement (R=0.92) is obtained (under present conditions) between the measured values of the IDA and those predicted by the developed ANN using the remaining 26 data sets as input parameters. The results indicate that the inundation damage is affected by not only meteorological information such as the rainfall amount, but also various environmental characteristics of the watersheds. So, the ANN proves its present ability to predict the IDA caused by an event of complex factors in a specific watershed area using accumulated temporal-spatial information, and it also shows a potential capability to handle complex non-linear dynamic phenomena of environmental changes. In this light, the ANN can be further harnessed to estimate the importance of certain input parameters to an output (e.g., the IDA in this study), quantify the significance of parameters involved in pre-existing models, and contribute to the presumption, selection, and calibration of input parameters of conventional models.
