The human chromosome analysis is widely used to diagnose genetic disease and various congenital anomalies. Many researches on automated chromosome karyotype analysis has been carried out, some of which produced commercial systems. However, there still remains much room or improving the accuracy of chromosome classification. In this paper, We propose an optimal pattern classifier by neural network to improve the accuracy of chromosome classification. The proposed pattern classifier was built up of multi-step multi-layer neural network(MMANN). We reconstructed chromosome image to improve the chromosome classification accuracy and extracted three morphological features parameters such as centromeric index(C.I.), relative length ratio(R.L.), and relative area ratio(R.A.). This Parameters employed as input in neural network by preprocessing twenty human chromosome images. The experiment results show that the chromosome classification error is reduced much more than that of the other classification methods.

The morphological properties of various structure materials of domestic and foreign reconstituted tobacco products(RTP) were investigated by using the Bauer-McNett classifier and the image analyzer. The results of the fiber classification showed the fraction of the bigger size structure materials was larger in a domestic RTP than that in two foreign RTPs. In case of fine fraction, the domestic RTP had bigger fine fraction than two foreign RTPs. Images of each structure materials showed the scrap in the foreign RTPs kept the original shape which were rare in the domestic RTP fractions. Those results deduced that the raw materials in a foreign RTP process might be treated separately depending on the mechanical and morphological properties, which could reduce the amount of fine generation and increase the efficiency in raw material treatment.

Horsehair or gordian worms (Nematomorpha) were identified with 22 genera (Gordiida) and 5 marine species (Nectonema) until now. During juvenile phase in development, they gain parasitic activity in arthropods. In this study, a gordian worm was detected in the feces of a dog living in Nonsan-si, Chungcheongnam-do, Korea. Using this worm, we evaluated the morphological characteristics by light microscopic analysis. Furthermore, the morphological classification was re-evaluated by scanning and transverse electron microscopes. The worm was determined that it is male adult having a bi-lobed tail and male gonads in cross sections. Based on the morphological characteristics including cross sections of body and areole on the cuticle, the parasite was also identified as Gordius sp. (Nematomorpha: Gordiidae).

This study was conducted to obtain the basic data for using the Artemisia genetic resources as a medicinal crop. 24 taxa including Artemisia capillaris Thunb. were analyzed by principal component analysis of 25 characters and cluster analysis for classification. In Principal components analysis of individuals of taxa using 25 morphological characters of reproductive organ, the first, the second, the third and the fourth components contributed 44.73%, 16.86%, 8.88%, and 7.07% of the variations, respectively. The cumulative contribution from the first to the fourth principal components was 77.56%. In cluster analysis, taxa of Artemisia L. was seperated 3 group by 25 morphological characters of reproductive organ, but it didn't completely coincident with Kitamura classification.

This study analyzed some of nursing homes in various domestic and foreign regions in order to find solutions to reduce suicidal incidents from the loneliness. To analyze community space of nursing homes, elderly community is analyzed into three categories based on their characteristics (morphological characteristics, Social characteristics, Environmental characteristics). With those three characteristics above, architectural spaces are analyzed the relation with them. Elderly nursing homes are divided with living, nursing, management, and public spaces. The space of elderly nursing homes (classification of function)-elderly community (classification of elderly characteristics) is approached in an architectural way related to the space of elderly nursing homes and elderly characteristics. Through some case studies, specific space relation of elderly nursing homes and elderly community is analyzed. Also, with the building analysis for summary, plans, wards(hospital rooms), cafeteria, program rooms and alley, some of general information and elderly community space is understood. In this study, there will be an analysis of relation of elderly community(morphological, social, environmental characteristics) which is separated into some spaces of elderly nursing homes(living, nursing, public spaces and facilities) written above. Furthermore, if people can recognize the importance of community space for elderly facilities, there will be a new guide line for that which can have a play on catalyst.

The morphological study was carried out to classify the spermatogenic germ cells of the seminiferous tubule in Korean Native Pheasant during the breeding season. The results were as follows : 1. The spermatogonia can be classified into the three types of A, In(intermediate) and B. 2. The primary spermatocyte can be classified into the five types as preleptotene, leptotene, zygotene, pachytene and diakinesis. 3. The maturing processes of nucleus of spermatid can be divided into seven steps. The round shape of the spermatid was changed to the elongated form during the spermiogenesis. This observation may be useful to the study of the breeding cycles in the Korean Native Pheasant.

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.

The majority of text categorization systems use the term-based classification method. However, because of too many terms, this method is not effective to classify the documents in areal-time environment. This paper presents a real-time concept-based text categorization system,which classifies texts using thesaurus. The system consists of a Korean morphological analyzer, athesaurus tool, and a probability-vector similarity measurer. The thesaurus tool acquires the meaningsof input terms and represents the text with not the term-vector but the concept-vector. Because theconcept-vector consists of semantic units with the small size, it makes the system enable to analyzethe text with real-time. As representing the meanings of the text, the vector supports theconcept-based classification. The probability-vector similarity measurer decides the subject of the textby calculating the vector similarity between the input text and each subject. In the experimentalresults, we show that the proposed system can effectively analyze texts with real-time and do aconcept-based classification. Moreover, the experiment informs that we must expand the thesaurustool for the better system.
