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".

CAI 프로그램 작성시 자료 공유를 위한 한자 공통코드 정의를 위하여 주요 한자문화권 국가의 한자 코드에 대한 고찰 결과, 한자코드 정의시 발음순과 부수순을 혼용 및 동일 한자에 대한 간체자(중국 GB)와 이체자(일본 Shift JIS)의 개발, 사용이 많아 정체자(KSC 한국)간의 자료 호환시 적절한 변환 장치가 요한다. 발음순 원칙은 동차 이음어가 다른 코드로 인식되어 코드 영역의 낭비가 있고, 부수순 원칙은 자국의 두음법칙에 맞지 않으나 중복 코드를 방지할 수 있어 자료의 복원시 유리하다. KSC 제1수준과 제2수준 한자 영역은 학계 및 업계의 요구를 수용할 수준으로 확대시킬 필요가 있다. 유니코드는 시스템의 호환, 확장에 유리하고, 다양한 문자 표현이 가능하여 교육목적 코드의 일시적인 대안이 될 수 있다.

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.

건축물 설계품질 및 생산성을 향상시키기 위한 다양한 BIM기반 실증적 연구 개발이 진행중이며, 인허가단계 전후로 건축법규 자동검토에 관한 연구 및 개발도 그 중 하나이다. 해당 연구 개발의 성과물 중 하나로써, 건축물 설계 적법성 자동검토를 위해 자연어로 기술된 건축법을 컴퓨터에서 실행 가능한 룰셋(KBimCode)으로 변환하는 메커니즘(KBimLogic)이 개발되었다. KBimCode는 표준성 및 중립성을 지향하며, 한국 건축법뿐만 아니라 타 국가의 건축법규나 설계지침서, 제안 요청서 등 다양한 설계 요구사항으로의 확대 적용이 가능하도록 개발되었다. 본 연구는 KBimCode를 타 국가 건축 법규로 확대 적용하여 그 표준성과 중립성 및 응용가능성을 검증하는것을 목적으로 한다. 이를 위하여 중국의 피난방화에 관한 건축법규를 대상으로, KBimCode 생성 메커니즘의 핵심인 논리규칙체계화의 세 가지 구성요소(객체속성, 함수, 문장 내외 관계)에 따라 구체적인 분석을 진행하였다. 그 결과, 다양한 중국 건축법규 문장을 KBimCode로 변환할 수 있었으며, 변환의 과정 중 다음을 도출할 수 있었다: 1) 건물 객체 및 그에 따른 속성에 대한 정의는 각 국가마다 상이하므로, 이를 고려한 객체 정의 및 속성 처리 방법이 필요하며, 2) 일부 문장은 서술부 및 문장 관계를 처리하기 위하여 새로운 함수 및 관계 유형 정의가 필요하며, 이는 KBimCode의 표준화된 함수 및 관계 유형 도출 규칙 안에서 확장 가능하다. 본 연구를 통해 전혀 새로운 대상의 변환과정에서의 문제점 등을 해결하는 과정을 통해 KBimCode의 가능성을 일부 검증하였으며, 다양한 대상 확대를 통해 표준적이고 국제적인 응용이 기대된다.

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.
