  • As the demand of English education is increasing, the demand for Native English speaking teachers (NEST) is rising, especially in Asian countries. However, due to the low number of NEST, the Korean government is suggesting that Filipino Women be used as English teachers as an alternative. This study aims to answer three questions: (1) are Filipino women in Korea qualified to teach English based on the error analysis of their written essays? (2) what are the linguistic features found in their diagnostic essays? and (3) is their written English better than Korean college students' written English based on the comparison of the two groups? The findings from the Filipino participants show the most frequently occurring errors are related to punctuation usage (commas and hyphens), vocabulary (word choice), verb usage, redundancy, and even as basic as capitalization usage. The results from the comparison of the two groups show that the percentage of the Filipino participants' written error was 14% while the percentage of the Korean participants was 17%. The findings would give us some ideas on the qualification of Filipino women in Korea as English teachers.

  • Objective : We proposed fundamental rules of prospective Korean Standard Classification of Diseases(Oriental Medicine). Methods : We analysed Korean Standard Classification of Diseases(Oriental Medicine)(established in 1994) in comparison with ICD-10 and Chinese Standard Classification of Disease(Traditional Chinese Medicine). Secondly, we analysed the diagnostic structure of Modem oriental medicine. Results : Korean Standard Classification of Diseases has an inappropriate writing structure, logical errors of classification, confusion of symptoms, 'bing', and 'zheng', inappropriate comparison of disease designations in oriental medicine and western medicine, and the ommission of important items. Secondly, we demonstrate the relations of 'bing' and 'zheng' in modem oriental medicine and disease designations in oriental medicine and western medicine. Conclusions : We propose the separate classification of 'bing' and 'zheng', the qualification of designated names, the structure of 'bing' and 'zheng' system, and a different writing method.

  • Though SLA(Stereolithography Apparatus) is being recognized as an innovative technology, it still can not be used to fully practical applications since it lacks of dimensional accuracy compared to conventional processes. In SLA, the accuracy of cured part depends upon the set of process parmeters. In order to improve the accuracy of SLA, this paper quantitatively evaluates how largely each process parameter of SLA contributes to the part accuracy and estimates the optimal set of process parameter which minimizes the dimensional errors of the test part, "letter-H" part. For this purpose, we use ANOVA(analysis of variance) and S/N(signal-to-noise)ratio of Taguchi method.hi method.

  • This paper presents an efficient modeling method for open cracked beam structures. An equivalent bending spring model is introduced to represent the structural weakening effect in the presence of open cracks. The proposed method adopts the exact dynamic element method (EDEM) to avoid the difficulty and numerical errors in association with re-meshing the structure. The proposed method is rigorously compared with a commercial finite element code. Experiments are also performed to validate the proposed modeling method. Finally, a diagnostic scheme for open cracked beam structures is proposed and demonstrated through a numerical example.

  • In this study we propose an approach based on statistical method which use the whole of saccades instead of using a few points of saccades in the quantitative analyse saccades. We computed statistical parameters such as mean velocity, quadratic mean velocity, standard duration, skewness of saccades velocity, flattness factor of saccades velocity, and mean delay by considering eye velocity as a probability density function. The results abtained are the following as ; This parameters showed the same trend like that of the main sequence. They were not biased by the systematic errors due to the arbitrary threshold. They were also less sensitive to noise, which was tested through the model simulation. So they are expected to provide a more comprehensive quantitative description of the dynamic properties of saccade in the diagnostic field.

  • This study was to improve to utilization of non dosimetry measurements for X-ray radiography. Experiments was passed off varying the X-ray tube voltage and the thickness of the aluminum filter by actual dose. Calculated results was set to the first beam quality factors, calculated first correction coefficient by the Microsoft Excel program was set as the second beam quality factors. To make the non dosimetry measurements simply, the Excel program apply to the new beam quality factors, the error was compared to the previous studies, and the results verify the calculated value of smaller errors.

  • The introduction of metagenomics into the field of virology has facilitated the exploration of viral communities in various natural habitats. Understanding the viral ecology of a variety of sample types throughout the biosphere is important per se, but it also has potential applications in clinical and diagnostic virology. However, the procedures used by viral metagenomics may produce technical errors, such as amplification bias, while public viral databases are very limited, which may hamper the determination of the viral diversity in samples. This review considers the current state of viral metagenomics, based on examples from Korean viral metagenomic studies-i.e., rice paddy soil, fermented foods, human gut, seawater, and the near-surface atmosphere. Viral metagenomics has become widespread due to various methodological developments, and much attention has been focused on studies that consider the intrinsic role of viruses that interact with their hosts.

  • On-site diagnosis of chiller performance is an essential step for energy saving business. The main purpose of the on-site diagnosis is to predict the COP of a target chiller. Many models based on thermodynamics background have been proposed for the purpose. However, they have to be modified from chiller to chiller and require deep insight into thermodynamics that most of field engineers are often lacking in. This study focuses on developing an easy-to-use diagnostic technique that is based on adaptive neuro-fuzzy inference system (ANFIS). Quality of the training data for ANFIS, sampled over June through September, is assessed by checking COP prediction errors. The architecture of the ANFIS, its error bounds, and collection of training data are described in detail.

  • Evaluation of toxicological pathology is to some extend subjective judgments by pathologist and the accuracy of pathologist's works is based on the individual training and experiences. It has been required to establish a peer review system for toxicologic pathology and these review system has been employed by various practice of toxicological pathology. It would be pointed out that the possible causes of drifts in pathology are due to 1) lack of knowledge or experience of individual pathologists, 2) poorly maintained consistence of grading among animals in study, 3) different interpretation of findings between pathologists, or 4) pathology data processing. Example cases of diagnostic errors and current practice of peer review including tissue selection criteria, documentation and problem resolution for short-term and carcinogenicity studies were introduced. For sound regulatory system and high integrity of practice in toxicological pathology, current approaches of peer review system were reviewed.

  • Bone scan is one of the most frequently peformed studios in nuclear medicine. In bone scan, the amount of radiolsotope taken up by lesion depends primarily on the local rate of bone turnover rather than on the bone mass. Bone scan is extremely sensitive for defecting bony abnormalities. However, abnormalities that appear on bone scan may not always represent disease. The normal scan appearances may be affected not only by skeletal physiology and anatomy but also by a variety of technical factors which can influence image quality. Many normal variants and artifacts may appear on bone scan. They could simulate a pathologic process and could mislead into the wrong diagnostic interpretation. Therefore, their recognition is necessary to avoid misdiagnosis. A nuclear medicine physician should be aware of variable appearance of the normal variants and artifacts on bone scan. In this article, a variety of normal variants and artifacts mimicking real pathologic lesion in bone scan interpretation are discussed and illustrated.
