One of the tasks of maritime navigation is to decide upon the optimal navigation route that minimizes a vessals travel time and fuel consumption. Recently. ECDIS(Electronic Chart Display Information System) is used to decide the optimal navigation route and have expert knowledge of maritime navigation. In this paper, the system use $A^*$algorithm for optimal navigation route on ECDIS. But some problems is discovered in this situation. it requires many memory device and searching time. So this paper has tried to develope a advanced algorithm system that decides the optimal navigation route.

Knowledge, technology and information have special characteristics different from the ones of normal consumer products and services. Especially the value of such information varies according to external elements such as the provided environment, their method of utilization, and the level and purpose, etc. of the user. In this study, the indicators of information customer value are developed and measured to enhance customer-based values with efforts for making new customers and maintaining existing customers. The result is as follows: 14 customer value indicators were developed. Among the indicators, value gained versus effort, reduced time for research idea investigation and savings in time searching for equipment, and tools and materials got the highest score, which means that time-saving effects were the most important. The field study of this paper was conducted from information users in the field of national R&D, and thus future studies could be conducted in various industries in many countries to attain generalized results.

The objective of this paper is to examine the structure of technology spillover from UAV(unmanned air vehicle) technology to other industries by applying patents analysis. The network analysis on patent data of USPTO(United Stated Patents and Trademark Office) from 1981 to 2000 was adopted to investigate the characteristic change of the technology spillover The results show that the influence of the UAV technology to other industries has grown over the twenty years period. For the weapon system development, this study provides a research basis to estimate the technology spillover effects on industries. Searching a structural niche from the inter-industrial knowledge flow structure might be a useful technique to find core technologies which generate large technology spillover on the other industries.

Objectives The purpose of this study is to investigate the recent Korean medicine treatment and study trends of tic disorder by reviewing clinical studies. Methods The clinical studies of Korean medicine treatment for tic disorder were obtained from National Discovery for Science Leader (NDSL), Research Information Sharing Service (RISS), Korean Traditional Knowledge Portal (KTKP) and Oriental Medicine Advanced Searching Integrated System (OASIS). Results 15 articles were analyzed to find out the most commonly used herbal medicine, acupoints, other Korean medicine treatments and evaluation methods. Conclusions This study shows some common Korean medicine treatment methods for tic disorder which can be used for further research.

The objective of this study was to investigate the diagnosis and treatment of Raynaud disease such as syndrome differentiation and herbal medicine by reviewing Chinese traditional medicine's journals. The journal search was carried out using China National Knowledge Infrastructure(CNKI) and PubMed from January 2008 to August 2013. Searching key words were the various combination of "Raynaud disease", "traditional chinese medicine", "syndrome differentiation", "herbal medicine". The final selection of 38 studies were selected and summarized by researchers. The syndrome differentiation was classified as yang deficiency and cold syncope, qi stagnation and blood stasis. The most frequently prescribed herbal medication was Dangguisinitang.

동영상 콘텐츠가 폭증하고 있으나 사용자가 동영상 내 장면에 내포된 개체(인물, 사건, 사물 등)를 직관적으로 검색하는 것은 어려운 상황이다. 현재 동영상 콘텐츠는 이용자들이 수동적으로 동영상보기, 다시보기, 정지 등으로 이용되고 있다. 이용자들이 능동적으로 인터랙티브하게 활용할 수 있도록 콘텐츠와 개체의 메타체계를 분석하여 장면단위로 콘텐츠의 정보를 검색을 할 수 있는 기능이 필요하다. 개체의 메타체계를 분석하여 시맨틱 모델(sematic model) 콘텐츠(Content) 온토롤지와 오브젝트(Object) 온톨로지 설계 및 2개의 온톨로지 연결을 통해 시맨틱 모델(sematic model) 접근할 수 있는 기능을 제시한다.

In very large databases, the problem of searching for interesting information effectively is very important in terms of efficiency and flexibility. A multiple layered database approach based on AOG(attribute-oriented generalization) method is one of the useful approaches for knowledge discovery under various situations. In this paper, we propose a multiple layered database design methodology based on AOG method in object-oriented databases. In addition, we propose a dynamic schema evolution model and implementation strategy in order to continue providing information effectively in multiple layered databases.

Priority queues can be used in applications such as scheduling, sorting, retrival based on a priority like gene searching, shortest paths computation. This paper proposes a data structure using array representation for double-ended priority queue in which insertion and deletion takes O(1) amortized time and O(logn) time, respectively. To the author's knowledge, all the published array-based data structures for double ended priority queue support O(logn) time insertion and deletion operations.

Objectives: The purpose of this study is to review the research in the cyclic treatment of endometriosis in traditional Korean medicine. Methods: By October 2019, the relevant studies on the periodic therapy of endometriosis were searched using the Chinese National Knowledge Infrastructure Database (CNKI) and Oriental Medicine Advanced Searching Integrated System (OASIS). Results: Finally, three Randomized controlled trials, one case study, two clinical observational studies were selected. In all studies, herbal medicine periodic therapy has been effective in improving symptoms of endometriosis. Blood-activating and stasis-dispelling medicinal were the most commonly used before menstruation and during menstruation, and tonifying and replenishing medicinal were the most commonly used after menstruation. According to the one study, which reported safety, herbal medicine was safe. Conclusions: Although limited due to a lack of literature, periodic therapy is effective in improving endometriosis related symptoms and preventing recurrence. A well-designed study and experimental studies for the identification of the mechanism are needed.

This paper deals with the expert system for power system recognition of energized and deenergized system using circuit breaker information. The basic idea is isolating the system with the system matrix representing the system configuration and the states of the circuit breakers. The knowledge base is composed of these isolated systems and decision rules. The isolated system with the sources is recognized as the energized system and the system without the source as the deenergized system. The rules use the system matrix and the the inference scheme is simplified in a great deal. Above all, the overall searching labor of the rules is independent on the system size and it is possible to expand into the real system and the real time restoration can be carried out easily. The expert system is written in PROLOG.
