Pen-tsao-kang-mu(Bon-cho-kang-mok), chinese medicinal plant book, was written by Lee sijin(1578), China. The subject of this study were 158 articles of vegetable part in Pen-tsao-kang-mu. Among them only 139 articles were able to be identified by authority of several references. By Engler's system they were classified into 8 divisions, 10 classes, 6 subclasses, 31 orders, 22 suborders, 52 families, 85 genera, 99 species, 12 varieties and 2 forma, and were confirmed 113 kinds of original plants. Among the divisions, Angiospermae was the most numerous division with 92 kinds(80.70%) and the second division was Fungi with 12 kinds(10.53%). The next was Rhodophyta with 4(3.51%) kinds. Other 19 articles were unable to be classified because of their ambiguous name.

To come up with the recommendations to improve the patent & trademark retrieval efficiency, 100,016 patent & trademark search requests by 17,559 unique users over a period of 193 days were analyzed. By analyzing 2,202 multi-query sessions, where one user issuing two or more queries consecutively, we discovered a number of retrieval efficiency improvements clues. The session analysis result also led to suggestions for new system features to help users reformulating queries. The patent & trademark retrieval users were found to be similar to the typical web users in certain aspects especially in issuing short queries. However, we also found that the patent & trademark retrieval users used Boolean operators more than the typical web search users. By analyzing the multi-query sessions, we found that the users had five intentions in reformulating queries such as paraphrasing, specialization, generalization, alternation, and interruption, which were also used by the web search engine users.

The platform safety door is difficult to install in platform because the doors of railway vehicles and existing Passenger Safety doors should be alined. To be able to solve this problem, we propose the use of Rope Type Platform Safe Door (RPSD) which is a vertically retractable platform that is designed to close from top to bottom. This platform has installed safety gate pillars at intervals of 20-40 m which accommodates different types of train regardless of train length, gate opening and location. In this paper, we reviewed the application of existing PSD and RPSD in various train stops in Seoul Gyeongbu Line platform. The results of the review showed that the existing PSD may cause problem in construction, safety and cost efficiency. The use of RPSD however shows that minimal problems will be encountered.

This paper defends Stalnaker's theory of indicative conditionals. His theory consists of selection functions and pragmatic constraints. The selection function takes a certain possible world(W) and a proposition(A) to yield a possilble world that is similar to W and in which A is true. And the pragmatic constraints plays role to make selection functions apply just to indicative conditionals. According to Stalnaker, as indicative conditionals has strong truth-value, uncontested principle always holds but passage principle does not always hold. However, his theory can explain why passage principle sometimes holds by means of pragmatic constraints. Also, this paper argues that Stalnaker's theory is the most acceptable one among others, by replying to criticisms suggested by Adamsians and the problem raised by Gibbard and other criticisms.

The purpose of this study was to investigate the directives and Wh-words in the directives from elementary 2nd, 4th and 6th grade Korean textbooks. After entering all directives into Microsoft Office Excel, directives with Wh-words were separated. The analysis program, Natmal, was used for the analysis of the directives and Wh-words. The criteria from previous studies were also applied for this analysis process. As a result of the study, there are a lot of nouns and verbs in directives. They were consisted of sentences with an average of 6.9 Eojeol. There were a total of 11 types of Wh-words and 'Mueot(what), Eotteon(which), eotteohge(how)' appeared most frequently in all grades. For question types, both grades had more inferential questions than literal information questions. This results were expected to be used as basic data for language interventions with school aged children who have language disorders.

새만금 유역 내에는 다수의 보 및 제수문이 위치하고 있으며, 관개, 배수, 오염원 등이 영향을 받고 있다. 선행연구 중에는 보 및 제수문을 고려하기 위해 모형의 소스코드를 일부 수정하여 연구되고 있으나 유역모형으로 구현하기에는 한계가 있으며, 이에 대한 연구는 미흡한 실정이다. 본 연구에서는 만경강 유역을 대상으로 유역 모형과 전산유체역학 모형을 이용하여 하류 제수문에 대한 유입, 유출 그리고 오염원 등의 영향을 분석하고자 한다. SWAT (Soil and water assessment tool)은 유역 모형으로 미국 농무부에서 농업유역의 수문순환 및 비점오염원을 모의하기 위해 개발한 모형이다. CFD (Computational fluid dynamics)는 전산유체역학 모형으로 구조물을 설계하고 유체, 기체 등을 모의할 수 있다. SWAT 모형을 이용하여 농업유역 하류 제수문 위치를 출구로 지정하여 수문을 모의하고 그 결과자료는 CFD에 입력할 수 있다. CFD는 하류 제수문 구조물을 설계하고 SWAT 모형의 수문자료를 입력하여 제수문의 영향을 평가할 수 있다. 우선, 만경강 유역을 대상유역으로 선정하고 부용, 황산, 상리, 고은교 등 제수문의 위치를 파악하였다. SWAT 모형 구축을 위해 2015-2018년까지 기상, 수위, 유량 관측자료를 수집하였으며, 보정기간과 검증기간은 각 2년이며, 모형 성능 검증에 사용한 적합성 평가 지수는 R² (Determine coefficient), RMSE (Root mean square error), 그리고 NSE (Nash-sutcliffe efficiency coefficient)를 사용하였다. 모형의 보정은 SWAT-CUP 자동보정프로그램을 사용하였으며, 모형의 보정지수는 NSE를 사용하였고, 1,000회 반복 수행을 통해 매개변수를 최적화하였다. 보정기간의 유출량 적합성 평가 지수는 R², RMSE 그리고 NSE가 각각 0.84, 2.96 mm/day, 0.70을 나타냈다. 검증기간의 유출량 적합성 평가 지수는 R², RMSE 그리고 NSE가 각각 0.72, 2.94 mm/day, 0.46을 나타냈다. 본 연구는 유역 차원과 구조물 차원의 모델링을 연계하는 것으로 향후 제수문 모니터링 자료를 활용하여 CFD 모형을 구축하고 유입량에 따른 제수문의 검보정 및 영향을 평가하고자 한다. 이러한 결과는 최근 기후변화에 따라 급격히 변화하는 유역환경에 대처할 수 있는 방안이 될 수 있을 것이며, 제수문 시설을 관리하는 기관에서도 합리적인 운영방안에 대한 기초자료로 기여할 수 있을 것으로 사료된다.

This research has a purpose to help academic high school students to choose their own career by developing an examination that distinguishes between liberal arts and natural sciences. Besides an aptitude test, I identified the necessity of a tool for distinguishing liberal arts and natural sciences, using an examination tool that uses puzzles to distinguish liberal arts and natural sciences and conducted the first examination. On the basis of the result of the first examination I made the second examination test, and the algorithm. After conducting the second examination to a variety of target subjects, like academic high school students, university students, and graduate students through the second examination paper and algorithm for distinguishing liberal arts and natural sciences, competent results have been deducted.

Recently Professor Lee has suggested the analysis of the indicative conditional based on Sellars-Brandom's inferentialism. In this paper, I raise three questions. First, Professor Lee seems to misunderstand Sellars-Brandom in that he considers only the analytically valid arguments as materially valid inferences. Second, Professor Lee seems to misunderstand Sellars-Brandom in that whereas Sellars-Brandom talks about the common features of all kinds of conditionals including counterfactual conditionals, Professor Lee takes it as the analysis of the indicative conditional only. Third, either Professor Lee's analysis is incompatible with Sellars-Brandom inferentialism or his analysis is too general.

This study examines a study of communication factor in the Chinese augury bone, as a communication text, a communication history text and a communication thought text, in terms of sender message channel audience effects, interdisciplinary research. In many respects, it is generally accepted that the Chinese augury bone have been the generic references of the Oriental culture. Based on various research results about The Chinese augury boney as a communication text, this paper explores factors of communication text related with meta-communication as the definition of communication and a structure of communication, a method of communication. The Chinese augury bone consider graphic element as communication tool, its manager as sender or communicator, the record as message, the bone as channel, its reader as audience, text understanding and behavior as effects, the augury bone producer as journalist, the tying bone in a bundle as old style book. In the Chinese augury bone, one property of communication thought is that the political ideology, which is related to the strong and weak of the graphic style and determines the naming method of kings.
