An effective method was proposed in this study which can improve the strengthening effect of continuous girder bridges by external tendons. The improvement of the proposed strengthening method in comparison with conventional methods was analyzed by applying equivalent load concept. In order to verify the strengthening effect, the enhancement of load-carrying capacity achieved by external prestressing was investigated through the test of continuous beams that were or were not strengthened by the external prestressing. The continuous beams were fabricated by making the deck slab continuous according to general construction practice of an actual concrete girder bridge. The test results showed that the deflections and strains of the strengthened beam were significantly reduced when comparing with those of the non-strengthened beam for the same level of external loads, and the stiffness of the member increased by strengthening. In particular, it was verified that the proposed method can effectively reduce the tensile stresses of the deck caused by negative moment at the intermediate supports of a continuous bridge.

As an exploratory inquiry prior to developing a measure to assess Korean families with adolescents' family resilience, this study examined the construct validity of the family resilience measures that were developed in the U. S. Iowa Youth and Families Project(Conger & Elder, 1994): emotional support between spouses, problem solving style between spouses, and parenting behavior. The participants were 277 pairs of middle aged, middle class husbands and wives (554 individuals) who were the parents of first graders in middle schools in the metropolitan areas around Seoul. The results of exploratory and confirmatory factor analysis supported the construct validity, indicating that emotional support, problem solving style, and parenting behavior may be used as measures to assess Korean family resilience. However, further tests of convergent validity using various assessment methods and analytical procedures are needed to ensure the construct validity of family resilience measures.

Hand injury in children was increased due to multiple environmental risks and failed attention of parents to children in rapidly developing society. By the results of this evaluation in 37 cases, it was summarized as follows. First, hand injuries in children most commonly occurs in spring, and occurs more commonly in the children at the age of high activity. The most common level of injury is zone I by microreplantation zone, and zone II by tendon injury zone. The more desirable results were obtained by full thickness skin graft and composite graft if it were possible. For the better functional results compare to adults, the methods and procedures must be constructed after more evaluation with more clinical cases. In the cases of pediatric hand injury, the most important fact is prevention of injury, with the close attention by parents, and the second is appropriate diganosis and treatment for more functional results.

In this paper, we propose the index structure based on a vector approximation for efficiently supporting the similarity search of multi-dimensional data. The proposed index structure splits a region with the space partition method and allocates to the split region dynamic bits according to the distribution of data. Therefore, the index structure splits a region to the unoverlapped regions and can reduce the depth of the tree by storing the much region information of child nodes in a internal node. Our index structure represents the child node more exactly and provide the efficient search by representing the region information of the child node relatively using the region information of the parent node. We show that our proposed index structure is better than the existing index structure in various experiments. Experimental results show that our proposed index structure achieves about $40\%$ performance improvements on search performance over the existing method.

Schinzel-Giedion syndrome is a rare, distinct dysmorphic syndrome characterized by congenital hydronephrosis, skeletal dysplasia, and severe developmental retardation, likely to be inherited as an autosomal recessive trait, but not yet confirmed. This syndrome is characterized by coarse facial features such as midfacial retraction, bulging forehead, short nose with anteverted nostrils, low-set malformed ears, protruding large tongue, and hypertelorism. Skeletal and limb defects, choanal stenosis, simian creases, hypospadias, microphallus, hypertrichosis, and intractable seizures are the frequently associated clinical findings. Urogenital involvement is a major component of the syndrome, and this problem sometimes is associated with nephrocalcinosis and urinary tract infection in the clinical course of the disease. We report a 22 month-old girl with Schinzel-Giedion syndrome complicated by medullary nephrocalcinosis and urinary tract infection due to Klebsiella pneumoniae. This patient had also been suffering from postnatal growth deficiency, intractable seizure, spastic tetraplegia, delayed development and severe mental retardation.

This study examines the actual operation status of the Korean children's library cultural program and analyzes the service type and operation status. Through this, it seeks the direction of cultural programs that can accommodate the needs of the users and establish the identity of the library. This study analyzes 856 kinds of cultural programs found on the homepage of 48 children's libraries in Korea. It was found that the lecture type programs for elementary school students were operated the most. In addition, most of the students participated one to three times during the lower grades of elementary school by their parents' recommendation. The satisfaction level of experiential cultural programs was the highest.

Provisions for the redistribution of negative moments in KCI 2007 and ACI 318-08 use a method for continuous flexural members subjected to uniformly-distributed gravity load. Moment redistributions and plastic rotations in beams of reinforced concrete moment frames subjected to lateral load differ from those in continuous flexural members due to gravity load. In the present study, a quantitative relationship between the moment redistribution and plastic rotation is established for beams subjected to both lateral and gravity loads. Based on the relationship, a design method for the redistribution of negative moments is proposed based on a plastic rotation capacity. The percentage change in negative moments in the beam was defined as a function of the tensile strain of re-bars at the section of maximum negative moment, which is determined by a section analysis at an ultimate state using KCI 2007 and ACI 318-08. Span, reinforcement ratio, cracked section stiffness, and strain-hardening behavior substantially affected the moment redistribution. Design guidelines and examples for the redistribution of the factored negative moments determined by elastic theory for beams under lateral load are presented.

The purpose of this study was to analyze the attitudes toward science and support for scientific activities of the scientific gifted students' parents and the general students' parents in elementary school. The objects of the study were 99 scientific gifted students and their parents and 433 general elementary school students and their parents. The instruments for the measurement of attitudes toward science included three scales: cognition :About value of science, affection toward science and science learning, and cognitive participation in scientific activities. The instrument to measure parents' support for scientific activities included two scales: indirect support and direct support. The results of the study showed that the attitudes toward science of scientific gifted elementary students' parents were more positive than the attitudes toward science of general elementary students' parents. Also the gifted elementary students' parents supported many more scientific activities for their children with various methods than the general elementary students' parents. Their preferring support methods for scientific activities included 16 items including the collection of information about science education, the record of TV science programs, purchase of scientific books, subscription of periodical publication about science, preparing material for scientific activities, and reading scientific book with children.
