Background: In this study, we investigated how to convert the Panax ginseng DNA sequence code and chemical fingerprints into a two-dimensional code. In order to improve the compression efficiency, GATC2Bytes and digital merger compression algorithms are proposed. Methods: HPLC chemical fingerprint data of 10 groups of P. ginseng from Northeast China and the internal transcribed spacer 2 (ITS2) sequence code as the DNA sequence code were ready for conversion. In order to convert such data into a two-dimensional code, the following six steps were performed: First, the chemical fingerprint characteristic data sets were obtained through the inflection filtering algorithm. Second, precompression processing of such data sets is undertaken. Third, precompression processing was undertaken with the P. ginseng DNA (ITS2) sequence codes. Fourth, the precompressed chemical fingerprint data and the DNA (ITS2) sequence code were combined in accordance with the set data format. Such combined data can be compressed by Zlib, an open source data compression algorithm. Finally, the compressed data generated a two-dimensional code called a quick response code (QR code). Results: Through the abovementioned converting process, it can be found that the number of bytes needed for storing P. ginseng chemical fingerprints and its DNA (ITS2) sequence code can be greatly reduced. After GTCA2Bytes algorithm processing, the ITS2 compression rate reaches 75% and the chemical fingerprint compression rate exceeds 99.65% via filtration and digital merger compression algorithm processing. Therefore, the overall compression ratio even exceeds 99.36%. The capacity of the formed QR code is around 0.5k, which can easily and successfully be read and identified by any smartphone. Conclusion: P. ginseng chemical fingerprints and its DNA (ITS2) sequence code can form a QR code after data processing, and therefore the QR code can be a perfect carrier of the authenticity and quality of P. ginseng information. This study provides a theoretical basis for the development of a quality traceability system of traditional Chinese medicine based on a two-dimensional code.

The Molten Salt Reactor (MSR), one of the six advanced reactor types of the 4th generation nuclear energy systems, has many impressive features including economic advantages, inherent safety and nuclear non-proliferation. This paper introduces a system analysis code named TREND, which is developed and used for the steady and transient simulation of MSRs. The TREND code calculates the distributions of pressure, velocity and temperature of single-phase flows by solving the conservation equations of mass, momentum and energy, along with a fluid state equation. Heat structures coupled with the fluid dynamics model is sufficient to meet the demands of modeling MSR system-level thermal-hydraulics. The core power is based on the point reactor neutron kinetics model calculated by the typical Runge-Kutta method. An incremental PID controller is inserted to adjust the operation behaviors. The verification and validation of the TREND code have been carried out in two aspects: detailed code-to-code comparison with established thermal-hydraulic system codes such as RELAP5, and validation with the experimental data from MSRE and the CIET facility (the University of California, Berkeley's Compact Integral Effects Test facility).The results indicate that TREND can be used in analyzing the transient behaviors of MSRs and will be improved by validating with more experimental results with the support of SINAP.

This study aims to clarify the identity of contemporary Chinese fashion design by examining how the characteristics of Chinese tradition are accepted and presented in fashion under the influences of western cultures. This study performed a literature survey on related works. Also this study performed demonstrative analysis of Chinese daily newspapers (People's Daily and Xinmin Evening News, 2007-2010) and fashion collections by Chinese and Chinese descent designers(2007-2011). The results are as follows: First, China is trying to express Chinese traditional ideas and factors in the design areas, and also trying to achieve an universal generalization. Second, the Chinese designers emphasized traditional ideas and culture in their designs. The Chinese descent designers were affected more by western culture. The common aesthetic consciousness were the beauties of sophisticated and splendorous decoration, vastness and elegance. Also the compromised images, neutral images and antique images were common in both groups. Third, the Chinese designers presented fashion designs on formalized and imitation stage. Also they tried to make a metaphorical stage. The Chinese descent designers showed designs on a metaphorical stage. In conclusion, the contemporary Chinese fashion design should find the way to globalize and identity of the traditional culture code simultaneously.

The purpose of this study was to find out the type of fashion codes hip-hop fashion has in contemporary Chinese fashion, and the frequency and characteristics of each fashion code. Text mining, which is the most basic analysis method in big data analyticswas used rather than traditional design element analysis. Specific results were as follows. First, hip-hop initially entered China in the late 1970s. The most historical turning point was the American film "Breakin". Second, frequency and word cloud analysis results showed that the "national tide" fashion code was the most notable code. Third, through word embedding analysis, fashion codes were divided into types of "original hip-hop codes", "trendy hip-hop codes", and "hip-hop codes grafted with traditional Chinese culture".

Writing a CAI program containing Chinese characters requires a common Chinese character code to share information for educational purposes. A Chinese character code setting needs to allow a mixed use of both vowel and stroke order, to represent Chinese characters in simplified Chinese as well as in Japanese version, and to have a conversion process for data exchange among different sets of Chinese codes. Waste in code area is expected when vowel order is used because heteronyms are recognized as different. However, using stroke order facilitates in data recovery preventing duplicate code generation, though it does not comply with the phonetic rule. We claim that the first and second level Chinese code area needs to be expanded as much as academic and industrial circles have demanded. Also, we assert that Unicode can be a temporary measure for an educational code system due to its interoperability, expandability, and expressivity of character sets.

Sanitary codes of retail ffod establishment of Korea, Japan, China, and America were reviewed in order to figure out the differences of the codes. The codes of Korea & Japan are similar in many aspects. The code of America regulates food safety procedures in detail and are easy to interpret. The code of China is broad and not specific in the procedures. Korean code deals with many administration affairs and Japanese code deals with food test and business. Chinese code also deals with administration and standards. American code defines 90 different terms while the codes of rest of the countries define only few terms. For sanitization American code specifies the procedures in specific terms in detail but others do not specify the procedures. For facilities, the American code specifies location, material and procedures but other codes also specify the material but the contents of the codes are not so much specific to compare with American code.

As one of empirical research and developments on BIM applications to improve design quality and productivity of building, efforts have been devoted to automated compliance checking of building design for building permit. KBimLogic is a mechanism that translate Korean Buidling Act to the computational language called KBimCode. KBimCode aims to standardized and neutral language that can be applied to various design rules. This paper focuses on testing expandability of KBimCode by appling it on Chinese Building Act. We analyzed Chinese national regulation on fire protection and evacuation, based on 1) Object·property, 2) function for predicate processing, 3) relationship of sentences. As a result, Chinese Building Act were successfully translated to KBimCode with some important implications for further application. Based on the finding of the paper, KBimCode is expected to be applicable to kinds of design rules.

Since 1979, the People's Republic of China has been opeining their marke tprogressively toward all over the world for developing its own domestic economy and international trade. China also has paid a great attention to the international maritime transport due to the fact that its volume of international trade has increased continuoulsy. Under such circumstance, the Chinese Maritime Code was issued in 1992 in which the regulation with regard to carrier's liability occupied an important position. The author, therefore, selected this issue for demonstration of the legal proinciples about carrier's liability which is provided in the Chinese Maritime Code. The study on the issue is under guidance of related international conventions. On the basis of the above, the differences between the Code and relevant conventions have been pointed out in order to make the people in the field of shipping understood for legal system with regard to carrier's liability in China which is a great potential partner of Korea in shipping and trade.

In this paper, we propose online Chinese character learning machine with a depth camera, where a system presents a Chinese character on a screen and a user is supposed to draw the presented Chinese character by his or her hand gesture. We develop the hand tracking method and suggest the adjusted chain code to represent constituent strokes of a Chinese character. For hand tracking, a fingertip is detected and verified. The adjusted chain code is designed to contain the information on order and relative length of each constituent stroke as well as the information on the directional variation of sample points. Such information is very efficient for a real-time match process and checking incorrectly drawn parts of a stroke.
