  • In a face detection system based on template matching, histogram equalization or log transform is applied to an input image for the intensity normalization and the image improvement. It is known that they are noneffective in improving an image with intensity distortion by illumination variation. In this paper, we propose an efficient image improvement method using a simple regression analysis combined with a bilateral symmetry average for images with intensity distortion by illumination variation. Experimental results show that our method delivers the detection performance better than previous methods and also remarkably reduces the number of face candidates.

  • A 2-year-old, castrated male Chihuahua dog was referred for revision surgery for reluxation of the patella following surgery for medial patellar luxation (MPL) of the left stifle joint. On general inspection, the patient showed bilateral hindlimb weight-bearing lameness. On physical examination, bilateral non-reducible MPL was detected through palpation. Radiographs revealed bone deformities of both hindlimbs. Computed tomography (CT) was applied for a three-dimensional (3D) printing bone model to establish an accurate surgical plan. The bone plate was pre-contoured over the 3D-printing bone model after execution of corrective osteotomy and sterilized prior to use in surgery. Corrective osteotomy was performed through a staged, bilateral procedure. The patient showed improvement of limb function following surgery without reluxation of the patella. The use of 3D-printing bone model for accurate surgical planning of corrective osteotomy appears to be effective in increasing the accuracy of surgery. That may lead to successful surgical outcomes.

  • Failure to change from the higher pitched voice of preadolescence to the lower pitched voice of adolescence and adulthood is called "mutational dysphonia" The voice is weak, thin, breathy, hoarse, and mono-pitched. If the voice theraphy was failed, surgery to lower vocal pitch which is refered to thyroplasty type III, is indicated. We compared the post-op acoustic parameters with pre-op data in unilateral antero-posterior shortening of the thyroid cartilage method and bilateral antero-posterior shortening of the thyroid cartilage method each other. Bilateral antero-posterior shortening of the thyroid cartilage method shows significant drop of fundamental frequency and speaking fundamental frequency statistically than unilateral shortening method. There was no significant differences in Jitter, Shimmer, SNR, MFR and other psychoacoustic analysiss parameters between two groups. These data shows that unequal tension of the vocal cord in uilateral antero-posterior shortening of the thyroid cartilage method does not control the pitch effectively so bilatreal shortening method in Type III thyroplasty is recommandable procedure in surgery of the mutational dysphonia.

  • It is well known that tardy ulnar nerve palsy occurs with cubitus valgus deformity as a late complication after a nonunion of lateral condyle fracture of the humerus in childhood. On the other hand, cubitus varus deformity often results from malunion of supracondylar fractures of the humerus. However, reports of tardy ulnar nerve palsy in cubitus varus deformity are few. We report a patient with bilateral cubitus varus deformities with bilateral tardy ulnar nerve palsy which was confirmed with EMG. She was treated by step cut osteotomy(DeRosa and Graziano) with sub­cutaneous anterior transposition of ulnar nerve.

  • The purpose of this study was to provide experimental evidence and theoretical background for the applicability of bilateral transfer paradigm to the rehabilitation programs for children with hemiplegic cerebral palsy. Children with hemiplegia, which means unilateral motor disabilities, display abnormal motor and postural patterns of the affected side due to hemiparesis, spasticity, and sensory disorders, resulting in a decreased motor abilities of the affected side compared to unaffected side. Accordingly, they tend to rely on the unaffected limb for everyday activities, which further deteriorates the functions of the affected side by causing associated reaction, abnormal postural patterns, and hypertonus. Rehabilitation programs developed for children with hemiplegic cerebral palsy include neurodevelopmental treatment, application of cast or splint to unaffected limb, neuromuscular electrical stimulation, and task oriented model. These programs, however, have several drawbacks, such as discontinuity in treatment effect and psychological hatred to the force use of the affected side. In order to solve these problems and enhance the efficiency of the rehabilitation programs, it is required to maximize the use of the affected side without hatred. Characteristics of the control system, such as temporal coupling and spatial assimilation between limbs and neural crosstalk at different levels of central motor pathway, suggest that the bilateral transfer paradigm may enhance the efficiency of the rehabilitation programs for children with hemiplegic cerebral palsy.

  • Purpose: This study aimed to measure the bilateral differences of facial lines in spherical coordinates from faces within a normal range of asymmetry utilizing cone-beam computed tomography (CBCT). Materials and Methods: CBCT scans from 22 females with normal symmetric-looking faces (mean age 24 years and 8 months) were selected for the study. The average menton deviation was $1.01{\pm}0.66$ mm. The spherical coordinates, length, and midsagittal and coronal inclination angles of the ramal and mandibular lines were calculated from CBCT. The bilateral differences in the facial lines were determined. Results: All of the study subjects had minimal bilateral differences of facial lines. The normal range of facial asymmetry of the ramal and mandibular lines was obtained in spherical coordinates. Conclusion: The normal range of facial asymmetry in the spherical coordinate system in this study should be useful as a reference for diagnosing facial asymmetry.

  • Inguinal hernia is the most frequent problem requiring surgery in children. Moreover, subsequent contralateral occurrence after repair of the symptomatic unilateral inguinal hernia(UIH) is not rare, This study is to evaluate the diagnostic value of inguinal ultrasonography (IUS) for potential bilateral inguinal hernia (BIH). A prospective study was performed for preschool children less than 6 years of age who were diagnosed as UIH from July 1999 to December 2000. We selected 58 cases with potential BIH, based on the past history, such as prematurity, ventriculo peritoneal shunt, family history of BIH. hernia on the left side (LIH), age below 2, female, and contralateral positive silk glove sign on the physical examination, Screening with IUS and bilateral surgical exploration were applied on these cases. Forty-seven cases were males (81.0%) and 11 cases were females (19.0%). Thirty four were infants. Symptomatic right inguinal hernia (RIH) were 28 (48.3%), and LIH were 30 cases (51.7%). Six cases had no evidence of contralateral patent process vaginalis (PPV) by IUS but showed contralateral PPV by operation. Two cases were suspicious to contralateral PPV under IUS, but operative findings were negative. Fifty cases showed contralateral PPV by IUS as well as operation. The detection rate of contralateral PPV under IUS was 86.2%. The preoperative IUS may reduce contralateral exploration.

  • The cochlear implantation(CI) as an useful tool for aural rehabilitation in bilateral severe to profound hearing impairment. However, CI prefer to usually one ear in spite of bilateral hearing impaired. because of the various characteristics of hearing loss, the hearing conservation for the future possibility, and socioeconomic condition of hearing impaired person and their families. The unilateral CI has limitations such as a directional loss, a difficult speech understanding in noise and a neural plasticity. These limitations will be overcome by hearing aid(HA) which is familiar with hearing impairer. but HA fitting for bimodal-binaural hearing are difficult because the difference output characteristic of HA and CI. This study will be confirm realities of use of HA in unilateral cochlear implantee. For this goal, 25(m:f=10:15) child participated who are used to HA for 1 to 17 months. We had telephone interviews with their mother about use of HA, change of auditory performance and own voice. As the results, hearing threshold levels of unimplanted ear, the use of a appropriate HA, implanted and aided hearing threshold level(HTL) are must be considered for successful biomodal-binaural hearing. Especially, implanted and aided HTL should be very useful parameter for a prediction of HA effect and a criterion of selection for bilateral cochlear implantation.
