The study of Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門) by Sonsamak(孫思邈) showed the following results. 1. The cause of Jungpung(中風) in Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門) was quotated from the theory of Naekyung(內經) -Pung(風) evil from the external environment invade on Hu(虛) of human body(外來風邪, 內虛邪中). 2. At Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門), he devided into the four classes of Jungpung(中風)'s symptom-Pyungo, Pungbi, Pungyi, Pungbi(偏枯, 風?, 風懿, 風痺)-, and this classification had a great influence on the next generations. 3. At Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門), he understanded that changes of Jungpung(中風)'s pathology depended on the Eum-Yang-Han-Yul-Hu-Shil(陰陽寒熱虛實) of the patients. 4. At Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門), he gathered and rearranged various prescription which accumulated the clinical experiences during the period from Naekyung(內經), Sanghan(傷寒) times, to Tang(唐)'s dynasty. There were major Jungpung(中風)'s prescription -Sosokmyungtang(小續命湯), Daesokmyungtang(大續命湯), Jukryuktang(竹瀝湯), Jihwangjun(地黃煎), Dokhwalgisaengtang(獨活寄生湯) etc. And the principle of treatment was the remedy method of removing evil through sweating(發汗祛邪法). 5. Chungumyobang(千金要方) showed the development of quality, quantity in their prescription comparing the fomer ages. And the method of classification of Jungpung(中風)'s symptom had a great influence on the next generation in clinical aspect. But the basic theory in Chungumyobang(千金要方) coudn't get out of the limits of Naekyung(內經), Gumgueyoryak(金?要略).

A practical animal face classification system that classifies animals in image and video data is considered as a pivotal topic in machine learning. In this research, we are proposing a novel method of fully connected dual Deep Convolutional Neural Network (DCNN), which extracts and analyzes image features on a large scale. With the inclusion of the state of the art Batch Normalization layer and Exponential Linear Unit (ELU) layer, our proposed DCNN has gained the capability of analyzing a large amount of dataset as well as extracting more features than before. For this research, we have built our dataset containing ten thousand animal faces of ten animal classes and a dual DCNN. The significance of our network is that it has four sets of convolutional functions that work laterally with each other. We used a relatively small amount of batch size and a large number of iteration to mitigate overfitting during the training session. We have also used image augmentation to vary the shapes of the training images for the better learning process. The results demonstrate that, with an accuracy rate of 92.0%, the proposed DCNN outruns its counterparts while causing less computing costs.

The factors contributing to learning can be broadly classified into four different groups; Learner's characteristic variable, Instructor's characteristic variable, Learning task characteristic variable and environmental characteristic variable. And the first thing we need to do here is understanding of learner's characteristics among those factors in order to devise a plan for education. Accordingly, the purpose of this study is to find out what impact the affective traits (self-concept learning habits learning attitude), one of the learner's features, have on the mathematics-learning achievement and to seek for a good teaching method with reference to elementary school students' learning accomplishments and attitudes. For this, a questionnaire survey was conducted of 78 students of two fifth-grade classes in an elementary school located in South Chungcheong Province in this study. In consequence, it has been shown that the mathematics-learning achievement has the greatest relevance to the self-concept in connection with mathematics followed by the self-concept in connection with learning, the learning habits relating to mathematics, the attitude towards mathematics, the learning habits concerning studies and the attitude towards learning.

The purpose of this study is to identify the supply status and planning trend of North Korean housing through analysis on the North Korean architecture specialized media data. The flat composition is changing and the living room is becoming the center of the houses. Also, in the urban areas, the standard apartment type is four apartments in a row and the plan form is getting diversified into circle type, Y type, and irregular type. On the other hand, in the rural areas, two houses in a row and single house are typical and the change in planning scale and space structure are not substantial. Since the 2000s, design changes have been made to emphasize the third dimensional structure of buildings such as the elliptical houses and L-shaped houses. Furthermore, 8~10 households are located on one floor which leads to the tendency of the building enlargement. In terms of house size, a square concept was introduced to replace the initial 2~3 room concept and the basic module of the room planning the 3 room house based on $3m{\times}3m$. However, there seems to be no standard house size, and the house size may differ depending on the social classandregion. In the early 1980s, when there was focus on the apartment complex construction, the high-rise apartment buildings of 30~40 floors was planned. However, during the Pyongyang redevelopment project, apartments of more or less than 10 floors were built and row-houses of more or less than 4 floors were built. In terms of the complex scale, a lot of small complexes of around 300 households are emerging after 2010. The construction projects are mainly limited to specific regions such as Pyongyang and Samjiyeon, and also limited to specific classes such as the workers and soldiers initially and the scientists lately. In addition, living boundary composition and ancillary facilities for sufficient green area ratio securement and the people of North Korea are maintained consistently. In recent years, the specialized floor planning such as solar house and the house for the disabled people, framework houses for redevelopment business, and multi-storied house construction technology are also emerging.

Fingerprint classification is useful to reduce the matching time of a huge fingerprint identification system by categorizing fingerprints into predefined classes according to their global features. Although global features are distributed diversly because of the uniqueness of a fingerprint, previous fingerprint classification methods extract global features non-adaptively from the fixed region for every fingerprint. We propose an novel method that extracts features adaptively for each fingerprint in order to classify various fingerprints effectively. It extracts ridge directional values as feature vectors from the region after searching the feature region by calculating variations of ridge directions, and classifies them using support vector machines. Experimental results with NIST4 database show that we have achieved a classification accuracy of 90.3% for the five-class problem and 93.7% for the four-class problem, and proved the validity of the proposed adaptive method by comparison with non-adaptively extracted feature vectors.

Fifty-four Pectobacterium carotovorum subsp. carotovorum strains isolated in Korea were characterized by a spectrum of antibacterial activities against 7 indicator strains chosen to represent various regions and host plants. All P. carotovorum subsp. carotovorum isolates tested could be grouped into 4 classes depending on the pattern of antibacterial substance production. All tested strains had DNA fragment(s) homologous to the genes encoding carotovoricin and 21 of them had genes homologous to DNA invertase. Sixteen strains had genes homologous to the genes encoding carocin S1. Several isolates produced antibacterial substances active against strains in Brenneria, Pantoea, and Pectobacterium genera that belonged formerly to the genus Erwinia. Strains in Pseudomonas or Xanthomonas sp. were not sensitive to the antibacterial substances produced by P. carotovorum subsp. carotovorum, except for X. albilineans that was sensitive to antibacterial substances produced by most strains in P. carotovorum subsp. carotovorum and P. betavasculorum KACC10056. These results demonstrated the diverse patterns of antibacterial substance production and the possibility of the existence of new antibacterial substance(s) produced by P. carotovorum subsp. carotovorum isolated in Korea.

This study proposed an integrated approach to multiplication as a way to help students understand multiplication in elementary mathematics. The integrated approach to multiplication is to give students a broad understanding of multiplication by solving a situation of multiplication in a variety of ways in mathematics classes, exploring and discussing each other's methods. The integrated approach to multiplication was derived from a number of previous studies that emphasized various approaches, a consistent approach, and a specific approach to multiplication. As results, the integrated approach of multiplication can be interpreted in four ways as a situation of multiplication, and each method is connected to important characteristics of multiplication emphasized in previous studies. In addition, this study has theoretically confirmed that the integrated approach to multiplication is important not only for multiplication but also for division, fraction and operation of fractions, ratios, rates, and proportions. This study is expected to provide some implications for teachers with regard to multiplication in elementary school mathematics.

Seventeen different herbicides were screened to select promising ones for the control of weeds, which may be used in paddy fields transplanted with 8 days old young rice seedlings. Four classes of herbicides were chosen and tested with seedlings grown under different cultivating conditions. Contact herbicides such as diphenyl-ether and oxadiazol showed severe growth retardation of rice seedlings. Carbamate class(dimepiperate), quinoline class (quinclorac), pyrazol class(pyrazolate), acid amide class(mefenacet and pretilachlor), addition of safener (pretilachlor+fenclorim and mefenacet+bensulfuron+dymuron) and unknown class (KC-7079) exhibited normal growth of seedlings. Sulfonyl urea herbicide class(cimosulfuron, bensulfuron, pyrazosulfuron), and oxarane class(tridiphane) showed the slight growth inhibition but recovered shortly.

A Clothing Department is a major fields of specialized vocational high schools. Specialized high schools with clothing related departments are located in Seoul (4 schools), Busan (2), Incheon (3), Daejeon (1), Ulsan (1), Kangwondo (1), Kyungkido (1), Kyungsangbukdo (1) and Chungcheongbukdo (1). In these 15 specialized high schools, 92 classes of clothing departments are run by 72 clothing teachers with 2,459 students enrolled. The range of object of this study is 15 clothing related departments of specialized high schools and their titles are department of Fashion Design, Clothing Design, Clothing Art, Multi Fashion Design, Fashion Textile Design, and Global Design. They were investigated by literature from previous research and education statistics from the Korean Educational Development Institute (KEDI). Websites such as 'School Information', 'portal site of Specialized High School', 'Ministry of Education-Education Statistics and Information' were also searched. The homepages of specialized high schools with clothing department were also investigated respectively. In this study, current scale, employment rate of graduates, major courses, scale of teachers of clothing major of clothing department of specialized high school were analyzed. In 2015, employment rate and college enrollment rate of vocational high schools were 46.6% and 36.6% respectively, whereas employment rate and college enrollment rate of clothing departments four specialized High Schools were 39.9% and 45.8% respectively. The number of major courses of clothing departments are 12-15, and the main subjects of the curriculum were Fashion Design, Construction of Western Clothing, Construction of Korean Clothing, Textile Materials and Mangement and Computer Graphics. Major courses consist of 90-108 weekly lesson-hours for 6 semesters. Thanks to government projects to encourage specialized high schools, the educational environment has improved in areas of practice room equipment, industry connections, field training, internship, and scholarship funds. However, despite government projects to encourage education at specialized high schools, there is a need for a more flexible education system to enhance student creativity at specialized high schools.

This study proposes fusion image matching method according to land cover property to generate a detailed DEM using the high resolution IKONOS-2 stereo pair. A classified image, consists of building, crop-land, forest, road and shadow-water, is produced by color image with four bands. Edges and points are also extracted from panchromatic image. Matching is performed by the cross-correlation computing after five classes are automatically selected in a reference image. In each of building class, crop-land class, forest class and road class, matching was performed by the grid and edge, only grid, only grid, grid and point, respectively. Shadow-water class was excepted in the matching because this area causes excessive error of the DEM. As the results, edge line, building and residential area could be expressed more dense than DEM by the conventional method.
