A photosynthetic cyanobacterium Arthrospira platensis, well known for health food supplement, was studied as a target species for atmospheric $CO_2$ removal as well as biomass production. Although the biomass of A. platensis was massively produced in many countries, the recovery cost of its biomass is still high. The purpose of this study was to develop the A. platensis mutant strains which have enhanced growth rate and floatation activity to reduce the recovery cost. A. platensis KCTC AG20590 was treated with 0.24% ethyl methanesulfonate (EMS) for 20 min at room temperature. The mutant strain A. platensis M20CJK3 was finally selected by its morphological and physiological features. The morphology of the mutant A. platensis M20CJK3 was changed from loose-coiled form to tight-coiled form showing short pitch. The growth and $CO_2$ uptake rate of A. platensis M20CJK3 were improved about 15% and 17% compared with A. platensis KCTC AG20590, respectively. The floatation activity of A. platensis M20CJK3 was enhanced in 2-fold compared with that of A. platensis KCTC AG20590. Soluble proteins extracted from two strains were analyzed by two dimensional electrophoresis (2-DE) and MALDI-TOF MS/MS. Among 15 protein spots induced in 2-DE analysis, two spots were the proteins related to photosynthesis and electron transfer system of the other cyanobacteria. As a consequence, it seems that the tight-coiled mutant A. platensis M20CJK3 has an advantage of high growth rate and floatation activity which are beneficial for the mass cultivation and recovery.

With CJK FTA as a starting point, this paper mainly studied the role of the logistics legal system in promoting marine industrial cooperation, facilitating investment trade, establishing international transport logistics, building marine economy international cooperation demonstration zone and deepening the economic and financial cooperation between China, Japan and Korea, and explored the way to establish an integrated logistics system between China, Japan and Korea to match the e-commerce certification system, online payment system and logistics distribution, thereby gradually promoting economic development and logistics integration in Northeast Asia, improving logistics efficiency, reducing logistics costs and establishing a unified logistics industry standardization system. This will accelerate logistics industry integration in Northeast Asia, build a unified logistics management center in Northeast Asia, and promote a new model of integrated logistics cooperation in Northeast Asia. Therefore, it has a practical and reference significance. In short, the improvement for the logistics legal system in CJK FTA is not the responsibility of a country or several countries. It concerns the development and prosperity for the logistics industry in the three countries and is an inevitable choice to promote the vigorous development of CJK FTA and economic take-off of each country.

최근 많은 양의 문서가 전자화되어 컴퓨터에 저장되고 인터넷을 통하여 공유가 되고 있고, 그 범위를 고문헌에까지 넓혀가고 있다. 그러나 한자 문화권의 고문헌은 대부분 2만에서 3만여자의 한자로 작섣되어 있어서 한자 입력시 코드문제가 뒤따른다. 하지만 유니코드 3.0에서는 27,786자의 한자를 코드화 하여 놓아서 한자 문화권 나라에 많은 도움을 주고 있다. 하지만 한중일 3개국에서 많이 쓰이는 한자를 대상으로 하여 부수, 획수 순으로 정렬하여 국내 실정에 맞지 않고 그나마 유니코드 한자를 입력할 수 있는 환경도 MS Word 2000 정도로 제한적이다. 본 논문에서는 유니코드 3.0 한자 입력기에서 기본 한자 코드로 상요될 CJK 한자 영역에 배정된 한자를 정렬하는 방안을 제안하고 운영체제 독립적인 한자 입력 시스템에 활용한다.

The purpose of this study is to investigate how individuals assess Chinese, Japanese, and Korean (CJK) transliterated bibliographic information on current library catalogs. Two separate studies, a survey and an experiment, were conducted using the WorldCat system. Users noted that Romanization has many issues which can inhibit user‘s ability to understand the transliterated bibliographic information even when it is in the person’s own native language and even when the individual had extensive experience with transliteration systems. The experimental results also supported these findings: participants had better results and satisfaction when looking for information written in English than when searching for transliterated information written in their native language. Implications for future research suggests a need to investigate user preferences for translation vs. transliteration of bibliographic information. This study proposes consideration of using English translation as a parallel link with CJK Romanization for bibliographic information.

본 논문에서는 소프트웨어 정의 네트워크를 이용한 한중일 한자-한국어 변환 키워드 도메인 이름 시스템을 제안하였다. 한자 체계를 주로 사용하는 한국, 중국, 일본에서 세 나라의 한자 수량이 너무 많기 때문에 우선 한국, 중국, 일본이 공용으로 사용하는 한자 체계인 CJK808을 가지고 연구하였다. 연구를 통해 CJK808 한자 체계에서 각 나라의 한자 특징도 많이 발견하였고, 그 중에서 표준자와 이체자의 다양성이 더욱 두드러졌다. SDN을 이용함으로써 관리 측면에서 다양한 이점을 얻을 수 있다. 제안하는 시스템을 통하여 사용자들은 한국, 중국, 일본 한자를 입력하면 SDN에서 관리하는 도메인 네임 서버를 통해 IP 주소를 얻을 수 있다.
