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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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.

Colors reprodued by color image processing system are affected by various physical factors and environmental conditions. Therefore it is difficult to reproduce the original object color accurately. Thus color calibrations of the input and output data of color image processing system based on spectral distributions are required. We propose a color calibration algorithm by considering spectral characteristic of the chosen color reproduction system which can be applied to device independent color reproduction using characteristic vectors of surface reflectance. The method comprised of two steps. The first step is color analysis step which reproduces the original object color from the camera output using color characteristic vectors. The second step is color synthesis step which displays the original color accurately on the monitor by considering the monitor's phosphor spectra. The spectral responsivities of camera sensors and phosphor spectral characteristics of a given monitor are evaluated. Also, to evaluate color reproducing characteristic we applied the proposed color calibration algorithm by choosing Macbeth ColorChecker's twenty four color spectra as a test color set. As a result, we reconstruct the actual color very closely on monitor using the proposed color calibration algorithm.

A retrospective study of operative results were carried out in a series of 164 patients who were performed microdiscectomy and 57 patients performed automated percutaneous lumbar discectomy (APLD) for herniated lumbar discs between January 1, 1990 and June 30, 1996 at the Department of Neurosurgery, Soonchunhyang University Hospital. The operative results were analysed, and the correlation between preoperative clinicoradiological factors and postoperative clinical results were statistically assessed. The major results were as follows : 1. Of 164 microdiscectomy cases, 102 were males and 62 were females, mean age was 42.4 years and incidence was the highest in the 5th decade, and of 57 APLD cases, 43 were male and 14 female, mean age was 32.2 years and incidence was the highest in the 3rd decade. 2. The preoperative symptoms and signs were lumbago(98.2%), radiating pain(96.3%), positive straight leg raising test(77.4%), motor weakness(27.4%), claudication(13.4%) & voiding difficulty(2.4%) in microdiscectomy cases, and lumbago(98.2%), radiating pain(98.2%), positive straight leg raising test(70.2%) & motor weakness(17.5%) in APLD cases. 3. Number of operated levels were performed 226 in microdiscectomy and 74 in APLD. The most commonly operated levels of two groups were L4-5 level. 4. Operative results 1) The overall success rates by Prolo's scale were 87.1% in microdiscectomy and 80.7% in APLD, respectively. 2) In younger age group (below 30 years) and in non-compensatory group, success rates were significantly higher in microdiscectomy. 3) As to protrusion and degeneration on MRI, clinical results of moderate protrusion and degeneration of discs in microdiscectomy were statistically significant, and those of mild protrusion and degeneration of discs in APLD were also statistically significant. 4) The most common cause of failure was inappropriate removal of disc material in microdiscectomy and sequestered discs in APLD. According to the above results, there were no differance in overall success rates between microdiscectomy and APLD. But clinical results seem to be influenced by the age, existence of compensation, and by the degree of protrusion and degeneration of discs as prognostic factors. If the selection of operative procedure between microdiscectomy and APLD for herniated lumbar disc is carefully done with clinical and radiologic findings of patients, good outcome might be achieved.

Most dynamic systems have various random properties in excitation and system parameters. Therefore, in this paper, reliability analysis for structural response is proposed fro the linear dynamic system with random properties in both excitation and system parameters. The system parameters and responses with random properties are modeled by the perturbation technique. A displacement and bending moment of frame structure is acquired in Stochastic Finite Element Method Program(SFEMP) and Dynamic Stochastic Finite Element Method Program(DSFEMP) using perturbation method, and Direct Monte Carlo Simulation Program(DMCSP) is used to verify and compare previous results. Comparing outputs of SFEMP and DSFEMP with them of DMCSP, it show that they are similar to each other. Also DMCSP need much time to analyze a complicated structure, but SFEMP and DSFEMP can reduce quite time. In this study, it is assumed that excitations, system parameters and response are Gaussian. The results of response for the analysis are compared to those of numerical simulation. Also the probability of failure are calculated for using Advanced First Order Second Moment(AFOSM) of the general reliability analysis method.

The purpose of this research was to a take a look at on-site applicability by implementing teaching design plans for physical education of elementary school students; furthermore, the Teaching Personal and Social Responsibility Model (TPSR) using a scaffolding strategy was used. In order to carry out the study, an analysis of the collected data on a teacher's activity evaluation sheets, class diary, in-depth interview with students, and written impressions of class, etc. were examined using a qualitative data analysis method. The results and discussion of this research are as follows: First, through the physical education for elementary school and TPSR class using scaffolding strategies, the students who had once ignored others and had not kept order began to control themselves and respect others' rights and feelings; Second, the students who had been mischievous in class and had not participated in school activities began to positively and faithfully participate in activities after class; Third, the students who had not participated in activities haphazardly and cursorily came to voluntarily take part in school activities through their own practice plan after school; Fourth, the students who had been self-centered and inconsiderate of others began to help other friends and show sympathy toward others; Fifth, the students who had only participated in class activities began to positively partake in extra-curricular activities, thus showing the effects of TPSR outside of the physical education context. The results of the current study suggests that it is necessary to use the TPSR method with a scaffolding strategy in elementary as well as junior & senior high school classrooms.

In the electrodeposition of copper foil for preparing printed circuit boards, a little amount of gelatin as a addition agent has been used for the better characteristics of a coat of electroplating. Gelatin modifies the physical properties such as mechanical strength, matte-side roughness, ultimate tensile strength(U.T.S), and elongation of copper foil, furthermore gelatin have influence on the structure of electrodeposits and the cathode polarization. The electrolyte used was of a composition; CuSO₄·5H₂O 300g/ℓ, H₂SO₄ 100g/ℓ, NaCl 10 ppm as a brightner, and was gelatin 0-7 ppm as a addition agent. Current density was 50 A/dm², and the temperature of electrolytic bath was 50 to 52 ℃. Experiments showed that the optimum gelatin concentration was 5 ppm with the consideration of the numbers of electrodeposited nuclei. And the nuclei numbers was sharply increased under 5 ppm, but was almostly constant above 5ppm. Average matte-side roughness by Surfcorder was gradually increased with the increasing gelatine concentration up to 2 ppm, and maximum roughness was observed at 2ppm. The roughness showed gradual decrease within the concentration range of 2 to 4 ppm, and was almost constant above 4ppm . Within the gelatine concentration range of 0 to 7 ppm, as the concentration increased, UTS was increased and elongation was decreased logarithmically. Also, in comparison between UTS and elongation, gelatin was identified as an addition agent acting inversely.

The inverted papilloma and squamous cell carcinoma are common neoplasia in the sinonasal cavity and nasopharynx, but the incidence of these tumors are very low and the study on the oncogenesis or biological activity of the tumor cells are not well known. This study was designed to evaluate the oncogenic roles of the p53 gene and the proliferative activity of the tumor cells in the inflammatory polyp, inverted papilloma and squamous cell carcinoma. The experiment was carried by the immunohistochemical stains about the p53 protein, PCNA and Ki-67, histochemical stain about the AgNORs. and flow cytometric analysis about the DNA ploidy using the formalin fixed paraffin embedded tissues. The frequency of the expression of p53 protein was 0%(0/16 cases) in the inflammatory polyps, 18.8% (3/16 cases) in the inverted papillomas, and 87.5%(14/16 cases) in the squamous cell carcinomas. The labelling index(%) of the PCNA and Ki-67 was 5.3% and 3.3% in the inflammatoy polyps, 29.6% and 25.2% in the inverted papillomas, and 51.9% and 36.8% in the squamous cell carcinoma. The expression of the PCNA and Ki-67 was distributed in the periphery of the tumor islands of the inverted papilloma and was distributed in the both of center and periphery of the tumor islands of the squamous cell carcinoma. The number of nuclear AgNORs was increased in the order of inflammatory polyps (0.96), inverted papillomas(1.34) and squamous cell carcinoma(2.09). The frequency of the DNA aneuploidy was 0%(0/16 cases) in the inflammatory polyps, 18.8%(3/16 cases) in the inverted papillomas. and 12.5%(2/16 cases) in the squamous cell carcinomas. Above results indicates that the changes of the p53 gene and proliferative activity of the tumor cells are involved on the oncogenesis and the biological activity of the inverted papilloma or squamous cell carcinoma in the nasopharynx and sinonasa cavity.

주제단원 중심 통합학습과 통합수행평가의 설계 방안 탐색

신재한 이화여자대학교 교과교육연구소 2008 교과교육학연구 Vol.12 No.3

본 연구에서는 기존의 통합교육과정과 통합교과의 문제점을 분석하고, 주제중심 통합학습의 개념 및 모형, 선행연구를 고찰하여 주제단원 중심 통합학습과 통합수행평가를 설계하는데 그 목적이 있다. 특히, ‘주제단원 중심 통합학습과 통합수행평가’는 현행 통합교육과정의 문제점과 통합교과 특성의 한계를 극복할 수 있는 대안적 통합학습으로서의 가능성을 확인할 수 있었다. 본 연구의 결론은 다음과 같다. 첫째, 통합의 한 가지 방법으로서 설계한 ‘주제단원 중심 통합학습’은 학교 교육과정과 괴리되지 않고 교육 현장의 교사들이 직접 활용할 수 있도록 주제단원 중심통합학습과 관련된 다양한 연수 프로그램을 개발해야 한다. 둘째, 본 연구에서 개발된 ‘주제단원중심 통합학습’은 수업과 평가가 이원화되는 것이 아니라, 학교에서 교과 단위 시간에 평가하는 수행평가와 연계하여 통합된 수행평가를 실시함으로써 교육 목표와 교육 평가가 일치하는 교육과정을 운영할 수 있다. 그러나, ‘주제단원 중심 통합학습과 통합수행평가’를 좀 더 효과적으로 실시하기 위해서는 주제단원 중심 통합학습과 통합수행평가를 실시하는 교사의 전문성을 함양할 수 있도록 연수기회의 확대와 통합학습에 대한 다양한 프로그램 보급이 우선시 되어야 하고 주제단원 중심 통합학습과 통합수행평가의 일반화를 위하여 효과성을 검증하고, 수정·보완함으로써 보다 다양한 통합학습의 교수·학습 방법을 활용할 수 있어야 한다. This study sets out to analyze the problems with the old integrated curricula and subjects,consider theme-centric integrated learning in terms of concept, model, and previous studies, anddesign theme unit-centric integrated learning and integrated performance evaluation. The resultsreveal that “theme unit-centric integrated learning and integrated performance evaluation” hadthe potential as alternative integrated learning to overcome the problems with the currentintegrated curricula and the limitations of the characteristics of the integrated subjects. The conclusions of the study are as follows: first, “theme unit-centric integrated learning”designed as one of approaches towards integration was not separated from the school curricula. It's necessary to develop a range of in-service training programs related to theme unit-centric integrated learning so that the teachers can make use of it in person. Secondly, “theme unit-centric integrated performance evaluation” developed in the study was combined with the performance evaluation carried out during the subject's unit hours in school instead of separating lessons and evaluations, thus helping to run a curriculum in which the educational goals would match the educational evaluations. In order to implement “theme unit-centric integrated learning and integrated performance evaluation” in a more effective way, there should be more chances for in-service training to help the teachers increase their professionalism related to the areas, and more diverse programs should be distributed in respect to integrated learning. Instructors need to utilize more diverse teaching and learning methods of integrated learning by testing the effects of theme unit-centric integrated learning and integrated performance evaluation, and further revising and supplementing them.

The cable-stayed bridges are composed of cables, towers and girders. when the cable-stayed bridges are loaded, the whole structure display very complex behavior due to excessive cable deflection. Eventhough the material in the members of a cable-stayed bridge structure behaviors in a linear elastic manner. the overall load-displacement relationship for the structure will be nonlinear. The nonlinear behavior is a result of: due to the sag caused by their own dead weight and the nonlinear axial and bending force-deformation relationships for the bend members. In the construction stage analysis, some technical approaches and structure safety are needed to stimulate numerically the complicated changes of structural system during construction. In this study static and construction stage analysis is performed and compared. Static and construction stage analysis on unsymmetric Cable-stayed bridge is performed and linear and nonlinear analysis is performed to evaluate the structure characteristics. After Static analysis of final construction stage was performed, construction stage analysis was performed.
