Community question and answering service is one of the main sources of information and knowledge in the Web. The quality of information in question and answer documents is determined by the clarity of the question and the relevance of the answers, and the readability of a document is a key factor for evaluating the quality. This study is to measure the quality of documents used in community question and answering service. For this purpose, we compare the frequency of occurrence by vocabulary level used in community documents and measure the readability index of documents by institution of author. To measure the readability index, we used the Dale-Chall formula which is calculated by vocabulary level and sentence length. The results show that the vocabulary used in the answers is more difficult than in the questions and the sentence length is longer. The gap in readability between questions and answers is also found by writing institution. The results of this study can be used as basic data for improving online counseling services.

인삼은 재배적지에 대한 선택성이 매우 강한 식물이며, 기후 토양 등의 자연환경이 적당하지 않으면 인삼의 생육이 곤란하고, 생육이 가능하더라도 생산된 인삼의 형태, 품질 및 약효에서 현저한 차이를 나타내고 있다. 이러한 인삼의 식물학적 특성이 우리나라에서는 최적의 환경조건으로 인정되어 고려인삼은 세계적으로 최고의 품질로 높이 평가되는 이유이다. 하지만 실질적인 인삼의 생리활성물질에 대한 연구는 서구열강 및 일본에 의해 대다수 연구, 발표되었으며 또한 인삼의 우수성을 인정하여 넓은 영토와 수많은 과학적 지식으로 고려인삼의 우수한 품질을 앞서가려 하고 있는 것이 현실정이다. 특히 중국의 넓은 인삼재배면적에서 값싸게 생산된 인삼이 한국시장을 위협하고 있으며, 미국과 캐나다에서 수많은 연구비를 투자하여 자국삼인 화기삼의 홍보를 대대적으로 함으로서 전세계의 인삼시장의 변화를 유도하고 있고, 호주, 뉴질랜드에서도 청정인삼을 내세워 한국 및 전세계 인삼시장을 잠식해가고 있다. 이런 변화에 의하여 한때 인삼의 종주국으로 전세계의 인삼시장을 석권했던 한국의 고려인삼이 과거의 위상을 점차 잃어 가고 있는 실정이다. 따라서 인삼재배면적이 경쟁국과 비교해 상대적으로 열세인 한국의 고려인삼이 선택할수 있는 방법은 비록 생산은 적더라도 고부가가치인삼을 생산하여 명품화로 가야 할 것으로 생각된다. 명품화를 위해서는 우선 고려인삼의 효능을 밝혀 고기능성을 입증해야하고, 재배생산단계에서부터 농약, 중금속등에 노출되지 않고 병에 자유로운 청정재배를 통해 명품화를 이룩해야 하며, 특히 제품의 생산 및 유통단계에서 표준화를 통해서 전세계의 소비자가 믿고 사용할수 있도록 해야 할 것이다. 또한 인삼에만 함유된 인삼사포닌(ginsenoside)은 배당체로서 여러 미생물에 의하여 당사슬이 끊어짐으로서 새로운 사포닌이 등장하게 되는데 이러한 사포닌이 각종 함암, 면적, 치매, 관절등에 탁월한 효능을 보임으서 많은 연구들이 진행중에 있으며, 특히 인삼에만 함유된 것으로 알고 있었던 ginsenoside가 돌외(한약재명 칠엽담)에도 함유되어 있고 일부 성분은 미생물을 통해서 변환시킴으로 서 값비싼 인삼사포닌을 생장이 빠르면 비교적 값싼 돌외 사포닌으로부터 생산할수 있게 되었다. 본 세미나에서는 각종 미생물을 이용하여 인삼의 사포닌을 변환시키고 돌외 사포닌인 gypenoside를 ginsenoside로 변환시켜 대량생산할 수 있는 방법을 제시하고자 한다.

An ontology as the core element of Semantic Web is a formal specification of a conceptualization of shared domain knowledge. The use of well-defined ontologies can increase the quality of interoperable information systems in the area of Semantic Web. However, in practice, it is not easy to develop high-quality ontologies which have no errors. Therefore, with methodologies for ontology design, various methods or tools for ontology analysis supporting for error-detection might be very helpful for ontology developers. In this paper, we propose a novel approach for analyzing the core constructs of ontology based on the Formal Concept Analysis and develop a tool that supports error-checking ontologies. Our approach can serve not only as a guidance to modify the existing ontologies, but also as a valuable tool in developing high-quality ontologies.

This study aimed at investigating present research and knowledge-base on climate change adaptation in ecosystem sector and analyzed the current status of basic information on ecosystem that functions as evidence-base of climate change adaptation to deduce the suggestions for the future development for knowledge and information in biodiversity. In this perspective, a questionary survey titled as "the ecological knowledge-base and information needs for climate change adaptation" with the researchers who were engaged with adaptation studies for biodiversity in the ecosystem related-research institutes including national and 17 regional local governments-affiliated agencies in Korea. The results are as follows; current status of utilizing ecological information which supports climate change adaptation strategy, future needs for adaptation knowledge and ecological information, and activation of utilizing ecological information. The majority of respondents (90.7%) replied that the ecological information has high relevance when conducting research on climate change adaptation. However, only half of all respondents (53.2%) agreed with the real viability of current information to the adaptation research. Particularly, urgent priority for researchers was deduced as intensifying knowledge-base and constructing related information on 'ecosystem change from climate change (productivity, community structure, food chain, phenology, range distribution, and number of individuals) with the overall improvement of information contents and its quality. The respondents emphasized with the necessity of conducting field surveys of local ecosystem and constructing ecosystem inventories, advancing monitoring designs for climate change in ecosystem, and case studies for regional ecosystem changes with the guidance or guidelines for monitoring ecosystem change to enhance the quality of adaptation research and produce related information. In terms of activation for ecological information usage, national and local adaptation network should be working based on the integrated ecological platform necessary to support exchanges of knowledge and information and to expand ecosystem types in time and spatial dimension.

Recently, interest in Korean Wave craze and K-beauty, led by K-pop, is increasing. In addition, the popularity and influence of the domestic beauty service industry has increased, and the economic and cultural ripple effects have been continuously expanding. The need to professional manpower training in response to the demand for manpower due to the growing development of domestic beauty services is emphasized, and the number of trainees who are actual consumers of beauty academy is increasing. Therefore, the purpose of our study is to examine the importance of quality factors of educational services to achieve educational purposes in the educational services provided by the Beauty Academy and the relationship between relationship commitment and educational service performance. Furthermore, it is to draw the importance of administrative support services, educational programs as well as educational service provision activities. However, the research for professional manpower training according to the provision of beauty services is insufficient compared to the development speed of the beauty industry. Therefore, at the present time when beauty service education is emphasized, our study will examine the relationship between relationship commitment and educational service performance based on the quality of education service by the students of domestic beauty academy. The measurement variables set for our study are program, instructor quality, tuition, external service, service fairness, relationship commitment, trust level, and educational service performance. The variables were analyzed and derived through the survey, and the following contents were derived from the empirical analysis. First, the quality of education service provided by the beauty academy, such as program, external service, service fairness, relationship commitment and trust level, had a significant effect on relationship commitment. Educational services provided by the institute, such as the systematicity and diversity of educational programs, enabled students to have a uniform relationship commitment. The quality of education service itself is to learn the expertise necessary for providing beauty service from the standpoint of the students and play an organic role in the relationship with the institute. Second, the moderating effect of trust level between academies and students was significant in the quality of education service and the relationship commitment. This means that students will feel higher level of service quality through the practical trust relationship of the students about the educational services provided by the institute. Based on the results of the empirical analysis, the implications of our study are to find ways to improve the students' ability and satisfaction represented by the results of educational services. This is because the quality of education services provided by the institute called Beauty Academy will have a great impact on the career choice of educational facilities and students. The characteristics of consistency, convenience, and knowledge orientation of education itself should be considered comprehensively, and a strong market position should be established through image formation through external service factors, which are external environments of academies.Furthermore, in terms of presenting differentiated strategies with competitors, the educational service quality factors play a significant role in the commitment to the relationship with the students, so the role of relationship marketing will be important for the psychological stability experienced by the students by grasping the demand accompanying the behavior of the students in advance.
