  • The purpose of this study was to investigate changes in balance and upper extremity (UE) function associated with reaching training for children with quadriplegic cerebral palsy based on Biomechanical Frame of Reference. The baseline (phase A) lasted one week. The therapeutic protocol consisted of three reaching training (Phase B) for 40 minutes three times a week. Intervention phases lasted 4 weeks. The CMS-70P (Zebris Medizintechnik Gmbh, Germany) was used to evaluate the qualitative changes in UE function and Pediathc Berg Balance Scale was used to test the balance. The observed performance changes seem to be associated with the presence of intervention and suggest that biomechanical training can be a useful intervention to improve not only manual function but also balance.

  • This study explored the experience of clinical nurses caring for foreign wives in Korea. A narrative study approach within the qualitative research paradigm was applied in this study. The data were collected using individual in-depth interviews with 10 clinical nurses who had at least 5 years working experiences caring for foreign wives and their children in the Women and Children's clinical setting. The narrative stories of the clinical nurses were analyzed in the frame of culture-bounded nursing care. In the culture-bounded nursing care, ethnocentric viewpoints, acceptable viewpoints, and culture-based viewpoints were identified within the time frame. Significantly, the narrator identified herself as a therapeutic caregiver in the culture-based viewpoints providing tailored caregiving for foreign wives. This study requires cultural sensitivity of nurses who care for the people with different cultural backgrounds. Self-awareness would be the starting point to reach culturally competent nursing care.

  • Non-homologous end joining (NHEJ), and to a lesser extent, the error-free pathway known as homology-directed repair (HDR) are cellular mechanisms for recovery from double-strand DNA breaks (DSB) induced by RNA-guided programmable nuclease CRISPR/Cas. Since NHEJ is equivalent to using a duck tape to stick two pieces of metals together, the outcome of this repair mechanism is prone to error. Any out-of-frame mutations or premature stop codons resulting from NHEJ repair mechanism are extremely handy for loss-of-function studies. Substitution of a mutation on the genome with the correct exogenous repair DNA requires coordination via an error-free HDR, for targeted transgenesis. However, several practical limitations exist in harnessing the potential of HDR to replace a faulty mutation for therapeutic purposes in all cell types and more so in somatic cells. In germ cells after the DSB, copying occurs from the homologous chromosome, which increases the chances of incorporation of exogenous DNA with some degree of homology into the genome compared with somatic cells where copying from the identical sister chromatid is always preferred. This review summarizes several strategies that have been implemented to increase the frequency of HDR with a focus on somatic cells. It also highlights the limitations of this technology in gene therapy and suggests specific solutions to circumvent those barriers.

  • Sensory integration started as a theory to provide a occupational therapist with a useful frame for explaining and intervening the problems which children have. Most researches on sensory processing disorder (SPD) have been found empirical evidence to support the sensory integration theory by measuring behavioral manifestations of SPD. Recently, researchers who are interested in the diagnosis of SPD have begun to use neurophysiological methods to establish objective evidence for sensory integration. These studies reported the neurophysiological indexes reflecting the maladaptive behaviors as well as the difference between children with SPD and typically developing children in using electrodermal activity, vagal tone, EEG. Future neurophysiological studies on SPD will be expected to prove the efficacy of sensory integration intervention.

  • Emodin (1,3,8-trihydroxy-6-methylanthraquinone) is a major constituent of rhubarb. Although it has been claimed to have a wild spectrum of therapeutic value, its side effects, especially in human kidney cells have not been well characterized. In this study, we have carried out in vitro genetic toxicity test of emodin and microarray analysis of differentially expressed genes in response to emodin. The result of Ames test showed mutations with emodin treatment in base substitution strain TA1535 both with and without exogenous metabolic activation. Likewise, emodin showed mutations in frame shift TA98 both with and without exogenous metabolic activation. The result of COMET assay in L5178Y cells with emodin treatment showed DNA damage both with and without exogenous metabolic activation. Emodin did not increase micronuclei in CHO cells both with and without exogenous metabolic activation. 150 Genes were selected as differentially expressed genes in response to emodin by microarray analysis and these genes would be candidate biomarkers of genetic toxic action of emodin.

  • Antibody phage display provides a powerful and efficient tool for the discovery and development of monoclonal antibodies for therapeutic and other applications. Antibody clones from synthetic libraries with optimized design features have several distinct advantages that include high stability, high levels of expression, and ease of downstream optimization and engineering. In this study, a fully synthetic human scFv library with six diversified CDRs was constructed by polymerase chain reaction assembly of overlapping oligonucleotides. In order to maximize the functional diversity of the library, a ${\beta}$-lactamase selection strategy was employed in which the assembled scFv gene repertoire was fused to the 5'-end of the ${\beta}$-lactamase gene, and in-frame scFv clones were enriched by carbenicillin selection. A final library with an estimated total diversity of $7.6{\times}10^9$, greater than 70% functional diversity, and diversification of all six CDRs was obtained after insertion of fully randomized CDR-H3 sequences into this proofread repertoire. The performance of the library was validated using a number of target antigens, against which multiple unique scFv sequences with dissociation constants in the nanomolar range were isolated.

  • Three-dimensional dose calculations based on CT images are fundamental to stereotactic radiosurgery for small intracranial tumor. In our stereotactic radiosurgery program, irradiations have been performed using the 6 MV photon beam of linear accelerator after stereotactic CT investigations of the target center through the beam's-eye view and the coordinates of BRW frame converted to that of radiosurgery. Also we can describe the tumor diameter and the shape in three dimensional configuration. Non-coplanar irradiation technique was developed that it consists of a combination of a moving field with a gantry angle of $140^{\circ}$, and a horizontal couch angle of $200^{\circ}C$ around the isocenter. In this radiosurgery technique, we provide the patient head setup in the base-ring holder and rotate around body axis. The total gantry moving range shows angle of 2520 degrees via two different types of gantry movement in a plane perpendicular to the axis of patient. The 3-D isodose curves overlapped to the tumor contours in screen and analytic dose profiles in calculation area were provided to calculate the thickness of $80\%$ of tumor center dose to $20\%$ of that. Furtheremore we provided the 3-D dose profiles in entire calculation plane. In this experiments, measured isodose curves in phantom irradiation have shown very similiar to that of computer generations.

  • In protein therapy, it is important for exogenous protein to be delivered into the target subcellular localization. To transduce a therapeutic protein into its specific subcellular localization, we synthesized nuclear localization signal (NLS) and membrane translocation sequence signal (MTS) peptides and produced a genetic in-frame SOD fusion protein. The purified SOD fusion proteins were efficiently transduced into mammalian cells with enzymatic activities. Immunofluorescence and Western blot analysis revealed that the SOD fusion proteins successfully transduced into the nucleus and the cytosol in the cells. The viability of cells treated with paraquat was markedly increased by the transduced fusion proteins. Thus, our results suggest that these peptides should be useful for targeting the specific localization of therapeutic proteins in various human diseases.

  • Purpose : A PC based brachytherapy planning system was developed to display dose distributions on simulation images by 2D isodose curve including the dose profiles, dose-volume histogram and 30 dose distributions. Materials and Methods : Brachytherapy dose planning software was developed especially for the Ir-192 source, which had been developed by KAERI as a substitute for the Co-60 source. The dose computation was achieved by searching for a pre-computed dose matrix which was tabulated as a function of radial and axial distance from a source. In the computation process, the effects of the tissue scattering correction factor and anisotropic dose distributions were included. The computed dose distributions were displayed in 2D film image including the profile dose, 3D isodose curves with wire frame forms and dosevolume histogram. Results : The brachytherapy dose plan was initiated by obtaining source positions on the principal plane of the source axis. The dose distributions in tissue were computed on a $200\times200\;(mm^2)$ plane on which the source axis was located at the center of the plane. The point doses along the longitudinal axis of the source were $4.5\~9.0\%$ smaller than those on the radial axis of the plane, due to the anisotropy created by the cylindrical shape of the source. When compared to manual calculation, the point doses showed $1\~5\%$ discrepancies from the benchmarking plan. The 2D dose distributions of different planes were matched to the same administered isodose level in order to analyze the shape of the optimized dose level. The accumulated dose-volume histogram, displayed as a function of the percentage volume of administered minimum dose level, was used to guide the volume analysis. Conclusion : This study evaluated the developed computerized dose planning system of brachytherapy. The dose distribution was displayed on the coronal, sagittal and axial planes with the dose histogram. The accumulated DVH and 3D dose distributions provided by the developed system may be useful tools for dose analysis in comparison with orthogonal dose planning.

  • Korean standard poetry with a fixed form are Rated Sijo. These Rated Sijos can be found in the 24 number of Gosijos. Then, why should Korean standard poetry be Rated Sijo? This is because only the Rated Sijo has a fixed form frame. Rated Sijo naturally tailored by a rigid framework is the best representation of Koreans' unique breath and temperament. Also, Rated Sijo is superior to general sijo or poem in terms of literary therapeutic utility for human body. If Haiku omits the end of narrative with the rated number of sounds and invites different imaginations to each reader, the Rated Sijo presents a certain frame to the direction of the human's rated signal by constructing the essence of the narrative with the rated number of sounds. Thus, the Rated Sijo suggests the way of human harmony and communication by inducing different imagination of readers cooperating in a certain direction. So, the famous poem of Korea, Rated Sijo, presents our future as a framework of literature that can contribute to the improvement of human communication and quality of life. Therefore, research to preserve and develop the value of the Rated Sijo should now be initiated and continued.
