Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

申載熙,卞種秀,朴準奉 慶北大學校 齒科大學 1986 慶北齒大論文集 Vol.3 No.1

butyl cyanoacrylate가 一般的인 縫合絲에 比해 齒 剝離搔爬術後 齒周辯膜의 治癒에 미치는 影響을 糾明하고자 5마리의 雜種犬 ( 6∼8kg )을 利用, 이들의 上下顎 左右 犬齒에 該當하는 頰側 附着齒 에 齒 剝離搔爬術을 施行하고 上記 2가지 方法을 區分하여 樂劑의 塗布 및 縫合을 施行한 後 定한 날에 實驗動物을 儀牲시켜 組織學的 檢鏡을 통해 이를 觀察하여 다음과 같이 結果를 얻었다. 組織學的 所見에서 初期에는 實驗部가 對照部에 比해 下部組織에 淨腫性 纖維素綱과 炎症細胞浸潤이 微弱하였고, 裂溝上皮細胞의 被服과 纖維性 骨膜의 形成이 迅速하였으며 纖維性 結締組織에 의한 齒周 膜과 齒面과의 癒合도 빨리 일어났다. releasing incision 部位에서도 實驗部가 炎症細胞浸潤이 보다 적었고, 肉茅組織의 形成이 迅速히 일어났으며 그 量도 적었다. 그러나 組織學的 觀察의 全 過程을 통해 3週에서는 治癒程度에 있어서 兩者間의 差異가 없었고, 4週에서도 兩者間의 治癒程道에 대한 差異를 觀察할 수 없었다. This is study was made in order to determine the histological changes associated with healing following the use of cyanoacrylates and silk sutures in canine areas where periodontal flap procedures had been carried out. In this experiment 5 adult mongrel dogs were used. The cyanoacrylate on the right side and black silk suture on the left buccal side of maxilla and mandibular canine area, were applied for the fixation of the flap after the periodontal flap surgery. On the experimental days, the experimental areas were examined clinically and sacrificed. Thereafter histological secimens were made following the useal methods and examined with light microscope. The results were as follows : In the histologic observations, the experimental areas as compared with the controls ; There was weak inflammatory cell infiltration and less edematous fibrin mesh formation at the substructure of the flap. The sulcus epithelial cell covering and formation of the fibrous periosteum was made rapidly. The union of periodontal flap and tooth surface by fibrous connective tissue was also made rapidly at the experimental areas. At the areas of the releasing incision less inflammatory cell infiltration and rapidity and small amount of granulation tissue formation were found. But through the entire procedure of the histologic observations, there was little difference in the degree of healing between the two in the 3rd week and it was also impossible to find the difference of healing between the two in the 4 th week.

The present work is concerned with the development of improved finite element for the nonlinear analysis of cable in cable-supported structure. Equivalent elastic modulus induced from parabolic function, generally used in the analysis of cable-supported structure, is shown that a result is good for the analysis of a structure with small-sagged cable, and it is simpler than that from catenary function which is the original shape of a cable. Therefore, it is used widely. But, In the analysis of a large-sagged structure, Equivalent elastic modulus induced from parabolic function can not have a accurate solution. Therefore, to solve this problem, equivalent elastic modulus induced from catenary function much expressed for the cable shape is used for the nonlinear analysis of large-sagged cable-supported structure. Equivalent elastic modulus, induced from a catenary function used in this study, is shown that the results obtained from 2-cases, small-sagged & large-sagged cases, are all good for the analysis of cable-supported nonlinearly behaving structures.

신기철,박재은,김재수,최상문,김우식 한국해양대학교 해양과학기술연구소 2001 硏究論文集 Vol.10 No.1

능동소나 시스템에서 표적신호의 근거리 정보가 중요해짐에 따라, 표적 음향산란 신호의 고유한특성을 분석하기 위해 실험적인 방법과 시뮬레이션 기법이 사용된다. 본 논문에서는 표적신호 합성을 위해 축소표적 반향실험을 수행하였고, 자료의 분석 결과 축소표적의 음향산란은 거울면 반사의 영향이 큰 것으로 분석되어, 표적신호 합성에서 기하광학이론을 응용하였다. 복잡한 형태의 표적을 여러 표본형상으로 분리하고, 각 표본형상의 기여도를 신호의 위상과 강도를 줌으로써 계산하였으며. 표적신호 합성모델의 검증을 위해 실제 축소표적 실험 결과와 비교하였다. 혁심용어: 기하광학이론. 음향산란, 거울면반사. 축소표적, 능동소나 투고분야: 수중음향 분야 (5.2) Since the near field iformation of target signal is important in the development and verification of active sonar system experimental method and simulation technique are widely used in order to analyze the detail characteristics of target scattered echoes. Therefore, in this paper, the scale target experiment is performed to develope and improve the target signal simulation model. Since the experimental results show that the specular reflection is the major component among scattering mechanisms, the target signal simulation model based on the Geometric Optics Theory (GOT) is developed. Complex target is separated into simple shapes, known as canonical shape. The contribution from individual canonical shapes are summed with proper phase and amplitude to produse the target strength of the whole complex body. Simulated target signal is compared with the experimental results fed discussed.

신승호,손충범,유재수 충북대학교 컴퓨터정보통신 연구소 2001 컴퓨터정보통신연구 Vol.9 No.2

XML문서는 정보 표현의 기본 단위인 엘리먼트로 구성되어져 있다. 이러한 정보 표현의 기본 단위인 엘리먼트가 XML문서 내에서 구조 변정 이 발생 할 경우 보다 빠른 검색을 위해 기존의 색인 구조 정보의 변경 없이 효율적으로 처리 되어져야 한다. 이를 위해 본 논문에서는 XML 문서의 구조 변정 시 기존의 색인 구조에 효을적으로 수용될 수 있는 동적 색인 모뗄을 제안한다. 본 논문에서 제안 하는 동적 색인 모뗄을 위한 구조정보는 기존의 EID(Element Id), ETID(Element TrPe Id), SORD(Sibling ORDer) SSORD(Same Sibling ORDer), Ccount 구조정보 추출 방법에 SSORD를 대신한 STSOL(Same TyPe Sibling ORDer List). Scount (STSOL내의 SORD 개수). 그리고 COL(Child ORDer List)을 추가함으로써 구성된다. 이러한 구조정보를 이용해 효율적인 검색을 지원하기 위한 동적 색인 구성 알고리즘을 기술하고 제한하는 색인 기법이 기존의 동적 색인을 지원하는 기법 보다 내용 색인, 구조 색인, 애트리뷰트 색인 측면에서 우수함을 성능 평가를 통해 보인다. XML documents consist of elements that are basic units of information. When the structure of XML documents is changed dynamically, we need to update structure information efficiently without changing the information of an index structure for fast retrieval In this Paper, we propose a dynamic index modelling scheme that update index struoture in real time as the structure of XML documents is changed by insertion and deletion of elements. In recent, for indexing XML documents. we have proposed a structural information representation method such as element ID(EID), element type ID(ETID), sibling order(SORD). same sibling order(SSORD) and child count(Ccount). Besides them, our proposed dynamic index modelling method in this paper extracts additional structural information, such as same type sibling order list(STSOL) that substitutes for SSORD. Scount that is the number of SORDS in STSOL. and child order Bist(COL). We design a dynamic indexing technique with our structural information. We show through various experiments that our method outperforms existing enes in processing various types of queries such as content based queries, structural queries and hybrid queries.

Urapidil, Labetalol의 투여가 기관내 삽관시 심혈관계에 미치는 영향

신용섭,윤석화,손수창,이원형,이정은,황원재,김만수,김영주,김혜자,최세진 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.

等高의 四角形 斷面 컵 形成

愼宰賢,任亨洙,徐大敎 成均館大學校 科學技術硏究所 1991 論文集 Vol.42 No.1

One of the recent procedures, the slip line field theory is adopted to find out the exact blank profile for deep drawing square and rectangular cups with a uniform height. The uniformity of drawn cup heights with ideal blanks by this theory is compared with that from other blanks. Drawing forces and thickness distributions are also described experimentally. From this approach, the use of ideal blanks could be suggested to obtain the deeper and the better square and rectangular cups with uniform heights which reduce the trimming allowance to a minimum.

신재수 대전대학교 기초과학연구소 1999 自然科學 Vol.10 No.1

고상반응법으로 Bi₂? Sr?CaCu₂O?와 Bi₂Sr?Ca?Cu₂o?시료를 작성하여 조성변화에 따른 상호치환상태와 초전적도특성에 관하여 알아보았다. Bi₂+ Sr?CaCu₂O?시료의 경우 -0.1≤x≤0.1영역에서 전형적인 Bi계 2212상의 단일상 (single phase)을 얻었다. x의 증가에 따라, a축과 b축의 길이는 거의 일정하고 c축의 길이는 감소하며, 임계온도 T?와 산소량은 증가하고 Bi의 유효가수는 감소하는 경향을 보이고 있다. 또한, Bi₂Sr?Ca?Cu₂o?시료의 경우, -0.2≤y≤0.8 영역에서 전형적인 Bi계 2212상의 단일상(single phase)을 얻었다. y의 증가에 따라, a, b c 축의 길이는 감소를 보이며, 임계온도 T?와 산소량은 감소하는 경향을 보이고 Bi의 유효가수는 약갼 증가하는 경향을 보이고 있다. EPMA and XPS on Bi₂Sr?CaCu₂O? and Bi₂Sr?Ca?Cu₂o? prepared by the solid-state reaction were performed in order to investigate superconductivity and mutual substitution state. In the Bi₂? Sr?CaCu₂O? singe phase samples were obtained in the range of -0.1≤x≤0.1. Within the solubility limit, the c-axis seemed to decrease with increasing x. In the region of the 80K singe phase, the T? and oxygen content increased with increase of x. corresponding to the decrease of the Bi mean valence. In the Bi₂Sr?Ca?Cu₂o?, singe phase samples were obtained in the range of -0.2≤y≤0.8 . Within the solubility limit, the a,b,c-axis seemed to decrease with increasing y. In the region of the 80K singe phase, the T? and oxygen content decreased with increase of y. corresponding to the increase of the Bi mean valence.
