As various genome projects have produced enormous amount of biosequence data, functional sequence analysis in terms of tile nucleic acid and protein becomes very significant. In functional genomics and proteomics, the functional analysis of each individual gene and protein remains a big challenge. Contrary to traditional studies, which regard proteins as not components of a whole protein interaction network but individual entities, recent studies have focused on examining functions and roles of each individual gene and protein in view of a whole life system. In this regard, it has been recognized as an appropriate method to analyze protein function on the basis of synthetic information of its interaction and domain modularity. In this context, this paper introduces the PIVS (Protein-protein interaction Inference & Visualization System), which predicts the interaction relationship of input proteins by taking advantage of information on homology degree, domain modules which input sequences contain, and protein interaction relationship. The information on domain modules can increase the accuracy of the function and interaction relationship analysis in terms of the specificity and sensitivity.

In this paper, a technology to protect important information from access in order to revitalize the cloud service market. A technology is proposed to solve the risk of leakage of important confidential and personal information stored in cloud systems, which is one of the various obstacles to the cloud service market. To protect important information, access control rights to cloud resources are granted to cloud service providers and general users. The system administrator has superuser authority to maintain and manage the system. Client computing services are managed by an external cloud service provider, and information is also stored in an external system. To protect important in-house information within the company, all users, it was designed to provide access authority with users including cloud service providers, only after they are authenticated. It is expected that the confidentiality of cloud computing resources and service reliability achieved through the proposed access control technology will contribute to revitalizing the cloud service market.

This study investigated the operation criteria of specialized complexes for horticultural production reflecting the farmers' preferences. First, the analysis of the communal activity included six factors: the group purchase of consumables for common activity, group purchase of the greenhouse apparatus, cooperative seed raising, use of a common air conditioning and heating system, cooperative shipping, and soil examination and certification system. The results of the Importance-Performance analysis can be summarized as follows. The factors requiring good management included the group purchase of consumables for common activity, group purchase of the greenhouse apparatus, and cooperative shipping. The factors with a lower priority included cooperative seed raising and the use of a common air conditioning and heating system. While the importance of the soil examination and certification system was low, the satisfaction was high, so this factor needs to be managed to avoid overkill. Second, the analysis of information exchange and education included six factors: production technique information, greenhouse facility management information, distribution-related information, production technique education, greenhouse facility management education, and distribution-related education. The results of the Importance-Performance analysis can be summarized as follows. The factor of production technique education was the most important determinant, plus the factors requiring good management included production technique information, greenhouse facility management information, and distribution-related information. The factors with a lower priority included greenhouse facility management education and distribution-related education. Therefore, to enhance productivity through facility modernization, the scaling up and creation of more specialized horticulture complexes are recommended as policy measures to gain export competitiveness. As the Korean government is expected to expand the scale of specialized horticulture complexes, the results of this paper can be widely utilized.

In this paper, impact of science and technology information service quality satisfaction and perceived importance on the user loyalty was studied to find the way of improvement of information service quality. To analyze the impact among service quality variables, the research questions and hypothesis are set and statistical analysis on 641 survey answers was conducted. The correlation between satisfaction and perceived importance regarding each service quality item was high. Relationship between satisfaction of every item of the service quality and overall satisfaction was verified by multiple regression analysis. As a result, the five out of seven independent variables are statistically significant influence to the dependent variable. Relationship between the perceived importance and loyalty for each item was verified by multiple regression analysis was confirmed that the four out of seven independent variables are statistically significant influence to the dependent variable. The overall satisfaction is having an effect on loyalty verified through simple regression analysis.

In the document extraction summary study, various methods for selecting important sentences based on the relationship between sentences were proposed. In the Korean document summary using the summation similarity of sentences, the summation similarity of the sentences was regarded as the amount of sentence information, and the summary sentences were extracted by selecting important sentences based on this. However, the problem is that it does not take into account the various importance that each sentence contributes to the entire document. Therefore, in this study, we propose a document extraction summary method that provides a summary by selecting important sentences based on the amount of quantitative and semantic information in the sentence. As a result, the extracted sentence agreement was 58.56% and the ROUGE-L score was 34, which was superior to the method using only the combined similarity. Compared to the deep learning-based method, the extraction method is lighter, but the performance is similar. Through this, it was confirmed that the method of compressing information based on semantic similarity between sentences is an important approach in document extraction summary. In addition, based on the quickly extracted summary, the document generation summary step can be effectively performed.
