Cognitive Spelling Therapist generates the candidates for correction of one-letter misspelling words, which correspond to over 80 % of the misspelling words. One-letter misspelling can be divided into four categories, and for each categories Cognitive Spelling Therapist copes them with seperate cognitive therapies. Each therapy is based on cognitive causes of misspelling: figural confusion, pronunciation confusion, and keyboard confusion. Cognitive Spelling Therapist generates three candidates for correction in average. After we tested the correctness of candidates with 185 misspelled words randomly sampled from two typist for two months, Cognitive Spell Therapist showed 97.5 % correction for substitution errors, while insertion, deletion, and transposition errors were perfectly corrected.

Uniform current distribution among conductor layers in HTS cables using IPTs (inter-phase transformers) was investigated. Conventional methods for current distribution, in which resistors are inserted to conductor layers, causes additional loss. In contrast, IPTs, which use magnetic coupling, make it possible that the current in parallel circuits is distributed uniformly with any load, and minimize the loss. In this study, IPTs were designed and fabricated for examination of uniform current distribution in the conductor layers of HTS cables. The ITP was designed through calculation of its impedance that can cancel the inductance of the conduction layers. The experimental setup consisted of four IPTs and four inductors that simulate the conductor layer inductance. Each layer was designed to feed 10 A. We examined the behavior of current distribution with IPTs for various layer inductances.

Benign paroxysmal positional vertigo(BPPV) is the most common peripheral vestibular disorder clinically. It causes dizziness or vertigo, lightheadedness, imbalance, and nausea. by a change of position of the head with respect to gravity. BPPV is very well explained by mechanical consequences of loose debris within the inner ear and oriental medical theory of vertigo resulting from Phlegm(痰). Therefore, for treatment of BPPV, we can consider not only oriental medical therapy but also Canalith Repositioning Procedure. We report four improved cases of dizziness patient diagnosed BPPV and Dam Hun(痰暈) treated by canalith repositioning procedure and herbal medication and acupuncture.

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent hereditary renal disease and causes terminal chronic renal failure. ADPKD is characterized by bilateral multiple renal cysts, which are produced by mutations of the PKD1 and PKD2 genes. PKD1 is located on chromosome 16 and encodes a protein that is involved in cell cycle regulation and intracellular calcium transport in epithelial cells and is responsible for 85% of ADPKD cases. Although nine cases of unilateral ADPKD with contralateral kidney agenesis have been reported, there have been no reports of early childhood ADPKD. Here, we report the only case of unilateral ADPKD with contralateral kidney dysplasia in the world in a four year-old girl who was intrauterinely diagnosed since she was 20 weeks old and followed for four years until present.

The primary purpose of this study was to evolve integrated design process for Experiential Design which is based on the former study, 'The Influence of Cognitive Factors on the Creative Abilities in Design'. Experience is a transformation factor to all of the design processes, which has three phase of problem solving; Input, Process, and Output. We regard Experiential Design is a transforming process from concept to experience, and set up a mode) of Holistic Design Process (HDP), which consists of four domains: Four Causes, Thinking Modes, Sensory Modalities, and Creative Abilities. Revolving Sensory Modalities (SM), Creative Abilities (CA), and Thinking Modes (TM) around Product Design Specification (PDS) through a design process, Design Concepts ripen and mature into Externalization. Each component of Experiential Design (TM, SM, and CA) turns around the PDS. Here, experience is first perceived by the five senses. Then, the knowledge is formed, and the CA works for a problem solving. And TM controls all of these procedures. We regard these are a phenomenon of Experiential Design. The HDP can be helpful to develop valuable solutions and create a good experience.

In parametric approach to a signature verification, it generally uses so many redundant features unsuitable for each individual signature that it causes harm, instead. This paper proposes a method of determining personalized weights of a feature set in signature verification with parametric approach by identifying the characteristics of each feature. For an individual signature, we define a degree of how difficult it is for any other person to forge the one's (called 'DFD' as the Degree of Forgery Difficulty). According to the statistical characteristics and the intuitional characteristics of each feature, the standard features are classified into four types. Four types of DFD functions are defined and applied into the distance calculation as a personalized weight factor. Using this method, the error rate of signature verification is reduced and the variation of the performance is less sensitive to the changes of decision threshold.

A method of establishing the tooth modification for gear transmission of vehicles to reduce gear whine noise, caused by tooth impact phenomenon of mating gear, is introduced. The major causes of tooth impact are due to the deflections of gear teeth and shafts of transmission with the loaded condition including various kinds of manufacturing errors. The theoretical shape of tooth surface to avoid tooth impact is derived by the amount of elastic deformation of gear teeth and shaft and overall manufacturing error of machine tool. The surface function is converted with respect to the conventional commercial data usually communicated to the gear inspection system. The proposed method is applied to the gearbox of four wheel drive vehicle and shows the gear whine noise decreased to the 8 dB in the sound level.

The existing six-bed patient rooms, general type of multiple-bed rooms in Korea causes many problems for the amenity of patients. We should reconsider their inconvenience carefully and try to provide the right to keep their privacy and enjoy amenity. The number of patients of multi-bed rooms is very critical point to improve the environmental condition of the patient rooms. So This paper aims to provide the possibilities of four-bed rooms through the comparison and analysis of six and four-bed room for planning and design.

Mucopolysaccharidosis III (MPS III, Sanfilippo syndrome) is a rare autosomal recessive disease caused by a deficiency of one of four enzymes involved in the degradation of glycosaminoglycan (GAG). The resultant cellular accumulation of GAG causes various clinical manifestations. MPS III is divided into four subtypes depending on the deficient enzyme. All the subtypes show similar clinical features and are characterized by progressive degeneration of the central nervous system. A number of genetic and biochemical diagnostic methods have been developed. However, there is no effective therapy available for any form of MPS III, with treatment currently limited to clinical management of neurological symptoms. Main purpose of the treatment for MPS III is to prevent neurologic deterioration. Because conventional intravenous enzyme replacement therapy (ERT) has a limitation due to inability to cross the blood-brain barrier, several innovative therapeutic approaches for MPS III are being developed. This review covers the currently developing new therapeutic options for MPS III including high dose ERT, substrate reduction therapy, intrathecal or intraventricular ERT, fusion protein delivery using bioengineering technology, and gene therapy.

Pseudomonas amygdali is a hemibiotrophic phytopathogen that causes disease in woody and herbaceous plants. Complete genomes of four P. amygdali pathovars were comparatively analyzed to decipher the impact of genomic diversity on host colonization. The pan-genome indicated that 3,928 core genes are conserved among pathovars, while 504-1,009 are unique to specific pathovars. The unique genome contained many mobile elements and exhibited a functional distribution different from the core genome. Genes involved in O-antigen biosynthesis and antimicrobial peptide resistance were significantly enriched for adaptation to hostile environments. While the type III secretion system was distributed in the core genome, unique genomes revealed a different organization of secretion systems as follows: type I in pv. tabaci, type II in pv. japonicus, type IV in pv. morsprunorum, and type VI in pv. lachrymans. These findings provide genetic insight into the dynamic interactions of the bacteria with plant hosts.
