Recently, the keyword 'convergence' has emerged in the education field. The voice of demand for the humanities is also increasing. The range of convergence of the humanities is gradually spreading to various fields such as science, technology, engineering, and the arts field. And also, the trend is to nurture the future creative convergence talent with logical, comprehensive, and creative thinking through the fusion of humanities, scientific, and empirical theories. Myths and legends contain the content of humanity's culture creation and deal with matters such as religion, philosophy, art, and science. Therefore, through the consciousness of the ancients who lived in the so-called convergence era when academic differentiation did not occur, it will be possible to reflect on the appearance of sages. In this paper, we propose a method for educating Chinese culture through the analysis of by Wen Yi-Duo, a famous Chinese scholar. He sought to find the origin of Chinese culture through myths and legends and to find national identity by restoring the concept of national culture in the period of origin. The myths and legends of China are closely related to the cultural phenomena of modern China, which will further enhance our understanding of China.

We investigated the effect of polymer sublayer on volumetric resistivity and tensile strength of carbon fiber (CF)/polyethylene composite films fabricated under high intensity electric fields. The dependence of volumetric resistivity and tensile strength of the films on the polymer sublayer thickness or mass part exhibited complex behavior according to CF content and CF layer density in the films. As the thickness of polymer sublayer increases, two groups of processes at thermo-mechanical forming stage would take effects in the properties of the films. The first group comprises the increase of polymer layer thickness having reduced CF content compared with central or upper part of the film and insufficient wetting of CF resulting in the loosened structure near upper film side. The second group, on the other hand, is the improvement of mobility of molten sublayer leading to better distribution of CF throughout the film thickness and the formation of more compact structure. The different degree of contribution of these two competing processes at varied CF content and CF layer density could explain complex dependence of the film properties on the polymer sublayer. These results are important to optimize the electrical and mechanical properties of highly conductive polymer films, which can be used as electromagnetic interference shielding materials.

Today, most documents are electronically produced and their paleography is digitalized by imaging, resulting in a tremendous number of electronic documents in the shape of images. Therefore, to process these document images, many methods of document structure analysis and recognition have already been proposed, including font classification. Accordingly, the current paper proposes a font classification method for document images that uses non-negative matrix factorization (NMF), which is able to learn part-based representations of objects. In the proposed method, spatially total features of font images are automatically extracted using NMF, then the appropriateness of the features specifying each font is investigated. The proposed method is expected to improve the performance of optical character recognition (OCR), document indexing, and retrieval systems, when such systems adopt a font classifier as a preprocessor.

This study is to review the historical documents about Cinnamomum camphora SIEB. in Goryeo and Joseon Dynasty. First of all, we defined it's feature and used case by the most appropriate word 'Jang(樟)' meaning Cinnamomum camphora SIEB. We also discovered some illusions and should suggest a new possibility. First, we analyzed the definition and examples of Cinnamomum camphora SIEB. and come to the conclusion that 'Jang(樟)' seems to be the most appropriate word. Second, we confirmed that Cinnamomum camphora SIEB. grew in extralimital area. It is believed that it's because of making a mistake. Third, we confirmed that it is confused Cinnamomum camphora SIEB. with Koelreuteria paniculata in Yi, Gyu-Gyeong's records. However, it's required to verify the other cases of the Cinnamomum camphora SIEB.'s records. We expect a follow-up study about it by classifying modern feature and comparing literature matching.

한국표준과학연구원에서는 국제표준화기구에서 제정한 국제규격(ISO, PNEUROP, DIN, JIS, AVS 등)에 기반을 둔 터보분자펌프의 특성평가시스템을 자체적으로 설계/제작 하였고, 터보분자펌프 1,000 L/s 급의 Database를 구축하였다. 이것을 토대로 특성평가시스템의 신뢰성 확인과 Feedback을 통한 시제품 개발 및 평가지원을 위해 터보분자펌프 2,500L/s 급의 Database를 구축한다. 터보분자펌프의 배기성능을 나타내는 가장 중요한 항목인 배기속도는 분자류 영역에 따라 상이한 가스($N_2$, He)를 사용하여 Throughput method와 Orifice method 두 가지 방법을 병행하여 측정한다. 측정함에 있어서 측정게이지, 유량계 및 Orifice conductance의 불확도에 의하여 배기 속도에 많은 측정오차를 포함하고 있다. 측정 오차를 줄이기 위하여 1% 이상의 안정성과 4%의 오차만을 허용하는 자전 회전자게이지(SRG)와 $10^{-3}$ mbar-L/s 영역까지의 유량 주입범위를 가지는 불확도 ${\pm}$3%의 정적형 유량시스템(CVFM)을 사용하였다. Orifice method의 경우 고진공영역으로 진입할수록 커질 수밖에 없는 배기속도 측정 불확도를 최소화하기 위해 검증된 유량을 이용한 Conductance 값을 제시하여 두 방법에서 얻은 배기속도의 불연속적인 문제를 해결한다. 본 연구에서는 2,500 L/s 급 터보분자펌프는 무거운 기체 $N_2$와 가벼운 기체 He을 사용하여 압축비의 변화와 분자류 영역에 따른 배기속도 변화를 연구하고, 2,500 L/s 급 터보분자펌프의 측정능력을 검증한다. 차후에 배기속도뿐만 아니라 소비전력, 소음, 진동, 온도 등의 특성평가의 전반적인 사항을 평가하여 터보분자펌프 2,500 L/s 급의 database를 완비해간다. 터보분자펌프 특성평가시스템을 사용한 1,000 L/s 급과 2,500 L/s 급 특성 Data를 비교, 분석하여 신뢰성 파악 및 표준화 방안을 개발하고, 고진공펌프 개발 주체와의 feedback 지원 기능의 infra를 구축한다.

The use of the friction coefficient is known to provide good discrimination ability in the classification of human constitutions, which are used in alternative medicine. In this study, a system that uses a multi-axis load cell and a hemi-circular probe is designed. The equipment consists of a sensor (load cell type, manufactured by the authors), an x-axis linear-bush guide motorized mobile stage that supports the hand being analyzed, and a signal conditioner. Using the proposed system, the friction coefficients from different constitutions were compared, and the relative repeatability error for the friction coefficient measurement was determined to be less than 2 %. The direction along the ring finger line was determined to be the optimum measurement region for a constitutional diagnosis between Tae-eumin and Soyangin types using the proposed system. There were some differences in the friction coefficient between the two constitutions, as reported in ancient literature. The proposed system is applicable to a quantitative constitutional diagnosis between Tae-eumin and Soyangin types within an acceptable level of uncertainty.

This study was conducted to obtain the basic informations for developing new varieties and cultural techniques for vegetable soybean at the Crop Experiment Station, Rural Development Administration, Suwon, Korea in 1992. Two vegetable soybean varieties, 'Hwaeom-putkong' and 'Seokryangputkong', and the other 'Jangyeobkong' for soy-paste were planted at three planting dates(April 15, May 15, June 15). The characteristics of growth, yield, and quality were compared between vegetable and soy-paste soybean genotypes in response to different planting dates.Vegetable soybean varieties, 'Hwaeomputkong' and 'Seokryangputkong' were more resistant to lodging, earlier in maturity, higher in the density of pod set on stem and percentage of poded nodes, and larger in grain size than Jangyeobkong for soy-paste. Earlier planting (April 15) of vegetable soybean varieties increased the yield of green pod as well as improved quality in number of green pods per 500g and length and width of green pod.
