  • The study alms to identify how the symbols and images of Greek Roman myths in contemporary fashion have been reflected in respects of meaning and forms, and to find out the organic course from meaning to forms by using Durand's classification. The results define the significance of Greek Roman myths in contemporary fashion, and systematically suggest a direction of imagination for more creative design. In the diurne regime, the symbolism of purity, heroism and fear appeared. In the nocturne regime, the symbolism of maternity and sensuality appeared. In the dramatic regime, the symbolism of androgyny appeared. The characteristics of designs contained in each symbolism are common. In this regard, it is possible to trace organic relationships in the creation of images through the verbal scheme. In addition, the verbal scheme creates archetypal images that lead to images and symbols in the socio-cultural context, so it is possible to analyze the relationships between archetypal images and the format of garments. The study examined how the archetypal images that appeared in the mythical images were expressed in garments through the verbal system.

  • Intensive taxonomical studies of the Aspergilli have long been made. Altogether 132 species and 18 varieties are recognized in the book "The Genus Aspergillus" written by Raper and Fennell (1965), in contrast to 77 species, 8 varieties and 4 mutations in " A Manual of Aspergilli" written 20 years earlier by Thom and Raper (1945). Classification of the Asperilli by Thom and Raper (1945) and by Raper and Fenell (1965). Classification of the Aspergilli by Thom and Raper (1945) and by Rapher and Fenell (1965) have been based mainly upon morphological and cultural detail both physiological and biochemical activities. In Korean there are many kinds of foods fermented natrually without the employment of selected microorganisms, and there are, of course, many different microorganisms serving in the fermentation fermented foods than other countries, the distribution and biological properties of the Asperigilli, in Korea are more variable. Taxonominical studies with 36 strains of Asperilli were based upon the examinations of morphological, cultural, and physiological characteristics. nineteen strains indigenous to Korea were selected from a lot of strains which had been isolated from meju and kokja and one strain from soil. They were identified according to the group key of Raper and Fennell. Ten strains were donated by Dr.Hesseltine of the Northern Utilization Research and Development Division in the U.S.A. From the Asp. japonicus supplied by Dr.Hesseltine, a white mutant was isolated and also studied. Two strains were donated by Dr. Murakami of the Research Institute of Brewing in Japan, and four strains came from Korean industrial companies.ndustrial companies.

  • An embryonic stem cell is a powerful tool for investigation of early development in vitro. The study of embryonic stem cell mediated neuronal differentiation allows for improved understanding of the mechanisms involved in embryonic neuronal development. We investigated expression profile changes using time course cDNA microarray to identify clues for the signaling network of neuronal differentiation. For the short time course microarray data, pattern analysis based on the quadratic regression method is an effective approach for identification and classification of a variety of expressed genes that have biological relevance. We studied the expression patterns, at each of 5 stages, after neuronal induction at the mRNA level of embryonic stem cells using the quadratic regression method for pattern analysis. As a result, a total of 316 genes (3.1%) including 166 (1.7%) informative genes in 8 possible expression patterns were identified by pattern analysis. Among the selected genes associated with neurological system, all three genes showing linearly increasing pattern over time, and one gene showing decreasing pattern over time, were verified by RT-PCR. Therefore, an increase in gene expression over time, in a linear pattern, may be associated with embryonic development. The genes: Tcfap2c, Ttr, Wnt3a, Btg2 and Foxk1 detected by pattern analysis, and verified by RT-PCR simultaneously, may be candidate markers associated with the development of the nervous system. Our study shows that pattern analysis, using the quadratic regression method, is very useful for investigation of time course cDNA microarray data. The pattern analysis used in this study has biological significance for the study of embryonic stem cells.

  • The objective of this study was to determine potential contributing factors associated with biosecurity level of farrow-to-finish pig farms and to develop a classification tree model to explore how these factors related to each other based on prediction model. To this end, the author analyzed data (n = 193) extracted from a cross-sectional study of 344 farrow-to-finish farms which was conducted between March and September 2014 aimed to explore swine disease status at farm level. Standardized questionnaires with information about basic demographical data and management practices were collected in each farm by on-site visit of trained veterinarians. For the classification of the data sets regarding biosecurity level as a dependent variable and predictor variables, Chi-squared Automatic Interaction Detection (CHAID) algorithm was applied for modeling classification tree. The statistics of misclassification risk was used to evaluate the fitness of the model in terms of prediction results. Categorical multivariate input data (40 variables) was used to construct a classification tree, and the target variable was biosecurity level dichotomized into low versus high. In general, the level of biosecurity was lower in the majority of farms studied, mainly due to the limited implementation of on-farm basic biosecurity measures aimed at controlling the potential introduction and transmission of swine diseases. The CHAID model illustrated the relative importance of significant predictors in explaining the level of biosecurity; maintenance of medical records of treatment and vaccination, use of dedicated clothing to enter the farm, installing fence surrounding the farm perimeter, and periodic monitoring of the herd using written biosecurity plan in place. The misclassification risk estimate of the prediction model was 0.145 with the standard error of 0.025, indicating that 85.5% of the cases could be classified correctly by using the decision rule based on the current tree. Although CHAID approach could provide detailed information and insight about interactions among factors associated with biosecurity level, further evaluation of potential bias intervened in the course of data collection should be included in future studies. In addition, there is still need to validate findings through the external dataset with larger sample size to improve the external validity of the current model.

  • Preconditions for the separation of prescribing and dispensing medicinal herbs in Traditional Korean Medicine are classification of medicinal herbs for general public and special medical uses, establishment of national medicinal herb distribution company of governmental base, restriction in purchase of medicinal herbs for special medical use, partnership between doctors and pharmacists of Traditional Korean Medicine, and coverage of herbal medicine-based medication in national health insurance, etc. The number of Traditional Korean Medicine Pharmacists which was born during 'the herbal medicine conflict' initiated in 1993, goes over 1,000 and will increase by 120 annually. The number of Traditional Korean Medical Doctors is over 17,000 and increases by 850 annually. So in order to engage partnership between two groups, the government have to arrange the number of outputs of each group. Standardization and classification of diagnosis and diseases in Traditional Korean Medicine is a matter of course in the separation of prescribing and dispensing medicinal herbs. Related societies and academies need to do researches with governmental fund first. After these works, we can launch a task force team for implementation of process for the separation of prescribing and dispensing medicinal herbs in Traditional Korean Medicine properly. Entering the national health insurance system for full coverage of Korean Medicine care service will be essential for the patients. Implementation the separation of prescribing and dispensing medicinal herbs in Traditional Korean Medicine would be the core of health insurance coverage for medication.

  • At present, GEOBIA (Geographic Object-based Image Analysis), heir of OBIA (Object-based Image Analysis), is regarded as an important methodology by object-oriented paradigm for remote sensing, dealing with geo-objects related to image segmentation and classification in the different view point of pixel-based processing. This also helps to directly link to GIS applications. Thus, GEOBIA software is on the booming. The main theme of this study is to look into the applicability of geo-spatial processing open source to GEOBIA. However, there is no few fully featured open source for GEOBIA which needs complicated schemes and algorithms, till It was carried out to implement a preliminary system for GEOBIA running an integrated and user-oriented environment. This work was performed by using various open sources such as OTB or PostgreSQL/PostGIS. Some points are different from the widely-used proprietary GEOBIA software. In this system, geo-objects are not file-based ones, but tightly linked with GIS layers in spatial database management system. The mean shift algorithm with parameters associated with spatial similarities or homogeneities is used for image segmentation. For classification process in this work, tree-based model of hierarchical network composing parent and child nodes is implemented by attribute join in the semi-automatic mode, unlike traditional image-based classification. Of course, this integrated GEOBIA system is on the progressing stage, and further works are necessary. It is expected that this approach helps to develop and to extend new applications such as urban mapping or change detection linked to GIS data sets using GEOBIA.

  • 기존에 단어의 빈도수를 근간으로 하는 문서 분류 시스템에서는 단일 키워드를 사용하기 때문에 사용자의 의도를 충분히 반영한 문서 분류가 어려웠다. 이러한 단점을 개선하기 위하여 우선 기존의 설명에 근거한 학습방법(explanation based learning)에서 한 예제만 있어도 지식베이스 정보와 함께 개념을 학습할 수 있다는 점에 착안하여 먼저 사용자 질의를 분석, 확장한 후 사용자 의도 트리를 생성한다. 이 의도 트리의 정보를 기존의 키워드 빈도 수에 근거한 문서분류 과정에 제약 및 보충 정보로 사용하여 사용자의 의도에 더욱더 근접한 웹 문서를 분류할 수 있다. 문서를 분류하는 측면에서 볼 때 구조화된 사용자 의도 정보는 단순한 키워드의 한계를 극복하여 문서 분류 과정에서 특정 키워드 빈도수의 임계값을 결정함으로서 잃게되는 문서 및 정보를 좀더 보유하고 재적용할 수 있게 된다. 질의에서 분석, 추출된 사용자 의도 트리는 기존의 통계 및 확률을 사용한 문서 분류기법들과 조합하여 사용자 의도정보를 제공함으로서 카테고리의 형성 방향과 범위를 결정하는데 높은 효율성을 보인다.
