  • The field tests were performed to suggest the rational method for stability evaluation of soft clay. The behavior of settlement-displacement obtained by field monitoring system was to compare and analyze the results of the observationed method, and to investigate the complex behavior of soft clay with filling height. The results of this study are summarized as follows. 1. The horizontal displacement was suddenly increased when physical properties of soft clay showed maximum values and the part of the turning point. The values of these properties were available to the fundamental data for stability evaluation. The shear deformation appeared that difference of the horizontal displacement was maximum values. 2. Although the stability of embankment by step filling showed the unstable part over the failure standard line, the embankment was confirmed stable. So the evaluation of the stability of embankment is reasonable to use the inclination of curve than failure standard line. 3. The horizontal displacement and relative settlement were increased as same ratio at improvement ground. Estimation of shear deformation using Terzaghi's modified bearing capacity should consider the relations of embankment load and undrained shear strength at nonimprovement ground, and minimum safety factor is recommended to use larger than 1.2. 4. Excess pore water pressure was increased with increasing of filling height and decreased with maintain the filling height. The embankment was unstable when filling height was exceed the evaluation standard line, and the behavior of excess pore water pressure and horizontal displacement could use as a standard of judgement of the filling velocity control because their behavior were agree with each other.

  • This study attempts to investigate the relations between the types of communication, the job satisfaction. and the nursing performance of the staff nurses. The subjects of this study were the 114 nurses working in general wards, intensive care units, and the emergency rooms of the general hospital in Kyongbuk province. They were asked to answer the questionnaires as regards the types of communication and job satisfaction, and their performance of nursing, and these were evaluated by the head nurses, and their direct seniors. The data were collected for 10 days from the September 17 to 26, 2002. According to the purpose of the study, descriptive analysis, ANOVA. Pearson correlation coefficient, and stepwise multiple regression were applied for the data analysis using SPSS 10.0. The results are as follows : 1. The types of communication of staff nurses showed that the upward communication was $3.12\pm0.56$. the downward communication was $3.56\pm0.42$. the horizontal communication was $2.98\pm0.44$. and the informal communication was $2.59\pm0.49$. It showed that the most frequent communication was the downward communication. 2. In terms of the job satisfaction, there was significant difference according to the length of the period working for one ward (F=5.95, p=0.003), 3. The performance of nursing was significantly different according to the age (F=23.52, p=0.000), the working duration as a nurses (F=21.9, p=0.000), the types of nursing unit (F=5.33, p=0.002), and the working duration in present nursing unit (F=15.87, p=0.000). 4. In terms of communication type, the job satisfaction was associated with quality of the upward communication (F=6.23, p=0.003), the downward communication (F=5.78, p=0.004), and the horizontal communication (F=11.73, p=0.000) There were no association between the types of communication and the performance of nursing. 5.

  • In order to implement an artificial intelligence lawyer, this study looked at how to structure legal principles, and then gave specific examples of how structured legal principles can be expressed in predicate logic. While previous studies suggested a method of introducing predicate logic for the reasoning engine of artificial intelligence lawyers, this study focused on the method of expressing legal principles with predicate logic based on the structural appearance of legal principles. Jurisprudence was limited to the content of articles and precedents, and the vertical hierarchy leading to 'law facts - legal requirements - legal effect' and the horizontal hierarchy leading to 'legal effect - defense - defense' were examined. In addition, legal facts were classified and explained that most of the legal facts can be usually expressed in unary or binary predicates. In future research, we plan to program the legal principle expressed in predicate logic and realize an inference engine for artificial intelligence lawyers.

  • The extended tangent stiffness matrices and force-deformation relations of the elastic catenary element were initially derived through the addition of the unstrained length of cables to unknown nodal displacements. A beam-column element was then introduced to model the deck and pylon of cable-stayed bridges. The conventional geometric nonlinear analysis, initial force method, and TCUD method were summarized, with an effective method combining two methods presented to determine the initial shapes of cable-stayed bridges with dead loads. In this combined method, TCUD method was applied to eliminate vertical and horizontal displacements at cable-supported points of decks and on top of pylons, respectively. The initial force method was also adopted to eliminate horizontal and vertical displacements of decks and pylons, Finally, the accuracy and validity of the proposed combined method were demonstrated through numerical examples.

  • Public libraries in Korea have undergone changes from libraries for just reading or keeping books to libraries with cultural facilities that provide information through various media. It was because of the "plan for building the information-oriented library" in 2000 that made the complexation of public library in progress. The alterations of the system have changed the structure as well as the grade ranks but haven't been considered enough for administrators or visitors. Hereupon, we are to study of the features by analyzing how the application of the system changed the structure of library. There are four stages in research methods. First, concept of public library and functional elements requested in the process of complexation were studied from literature. Second, vertical, horizontal and circulate changes were studied by applying subject libraries into prior research stereotyping the libraries. Third, mutual relations between each place were studied through J-Graph by elements. Lastly, rank changes according to centrality of space and users were quantitatively studied with space syntax. 4 notable changes were found in these analyses. (1)Vertical, horizontal and circulate structure of public libraries were homogenized. Since 2001, however, they have become diversified as all-in-one or detachable. (2)The space structure of library before 2001 was shallow tree shape while in 2001, period of transition, was the tree shape mixed with ring shape. As time goes on, it has become shallow tree shape again but connected by ring shape in part of reading and common space and in digital reference room. (3)Digital reference room was center of the space around 2001 and it ranked top for integration. After 2007, however, it has become setting off-center. (4)About the purpose of using public libraries, using it as space for administrators ranked top followed by space for visitors and common space before. For now, common space ranks top and space for visitors and administrators. 5 subject public libraries were selected respectively before and after 2001.

  • In this paper, we propose a disparity correction technique to reduce the inherent visual discomfort while watching stereoscopic videos. The visual discomfort must be solved for commercial 3D display systems to provide natural stereoscopic videos to human eyes. The proposed disparity correction technique consists of horizontal and vertical disparity corrections. The horizontal disparity correction is implemented by controlling the depth budget of stereoscopic video using the geometric relations of a stereoscopic camera system. In addition, the vertical disparity correction is implemented by using a feature-based stereo matching algorithm. Conventional vertical disparity corrections have been done by only using camera calibration parameters, which still cause systematic errors in vertical disparities. In this paper, we minimize the vertical disparity as small as possible by using a feature-based correction algorithm. Through the comparisons of conventional feature-based correction algorithms, we analyze the performance of the proposed technique.

  • The steel pipe of steel-concrete composite piles increases the pile strength and induces the ductile failure by constraining the deformation of the inner concrete. In this research, the load-movement relations and the reinforcement effect by the outer steel pipe in the steel-concrete composite pile were analyzed by performing three-dimensional numerical analyses, which can simulate the yielding behavior of the pile material and the elasto-plastic behavior of soils. The parameters analyzed in the study include three pile materials of steel, concrete and composite, pile diameter and loading direction. As the results, the axial capacity of the composite pile was 1.9 times larger than that of the steel pipe pile and similar with that of the concrete pile. At the allowable movement criteria, the horizontal capacity of the composite pile was 1.46 times larger than that of the steel pile and 1.25 times larger than that of the concrete pile. In addition, the horizontal movement at the pile head of the composite pile was about 78% of that of the steel pile and about 53% of that of the concrete pile, which showed that the movement reduction effect of the composite pile was significant and enables the economical design of drilled shafts.

  • It is very important to arrange the artificial teeth correctly in bucco-lingual (labio- lingual) relation in reconstrcting dentition. Although many anatomic landmarks and techniques have been reported over the years, they are based on westerns. So this study was performd to examine the horizontal relations of mandibular teeth in Korean dentulous adults. 200 volunteers(mean age 22.9) who had natural dentition were selected. The impressions were taken with irreversible hydrocolloid impression material and mandibular study models were fabricated using class I dental stone. Then they were measured with 3-dimensional measuring device specially designed for this study. The results were as follows ; It is better to consider the lingual cusps of the lower posterior teeth as a guide than the linguoaxial surfaces of the lower posterior teeth, arranging the lower posterior teeth buccally to the line which starts from the mesial aspect of the lower canine and continue backward to the lingual aspect of the retromolar pad. It is better to arrange the fossae of the lower posterior teeth buccally to the line which starts from the cusp tip of the lower canine and continue backward to the top of the retromolar pad. The positions of the lower posterior teeth in the denture-bearing area ; considering the fossa as a guide, the 2nd premolar was positioned in center. considering the buccal cusp as a guide, the 1st molar and the 2nd molar were positioned in center. the distance ratio(d/a) was incresed constantly from the lower canine to the 2nd molar d ; the distance between the buccal vestibule(the lowest point) and the buccal cusp tips of the lower posterior teeth. a ; the distance between the buccal vestibule(the lowest point) and the lingual vestibule(the lowest point). The lower canine was positioned lingually($0.11{\pm}0.13$) than the labial vestibule, and the central incisor and the lateral incisor were positioned almost in the imaginary perpendicular plane of the labial vestibule(the lowest point).
