Fig. 1. shows deformations of two near arbitrary members of rigid frame in this report. A. general equation on of relative displacement of Diagonal joints is Δℓ=y_(m)/EK_(O)(F_(m)a_(m)/k_(m)+F_(m+1)a_(m+1)/k_(m+1)) If this displacement is "O", the equation transfer F_(m)a_(m)/k_(m)+F_(m+1)a_(m+1)/k_(m+1)=O By this process, we can make simple simultaneous equations that's demensions is end moment. Rigid frame can be analysed by solving this simultaneous equations.

C++ 점진적 의미 분석기 설계

The rapid growth of user interface parts due to the increased power of computing makes the information shown to users be updated quickly as the actions of users. The core of applications with this facility is incremental processing technique. As the use of this technique in the programming area, many incremental systems were developed. When the techniques used in these systems, which analyze the program incrementally using attribute grammar, are applied to object-oriented languages which have complex naming semantics, it become inefficient. An example of this is class in which names depends on the classification hierarchy and not only on block structure. In this study we designed the classes and relating data structures which was needed to solve these problems for incremental name analysis for C++.

돌연변이성에 의한 수중유기 오염물질의 독성평가

유영식,채수권,권우택,김남천 서울보건대학 1996 서울보건대학 부설 한국보건과학연구소 논문집 Vol.3 No.1

한강수계 팔당댐 유입 하천수를 대상으로, 다환방향족 탄화수소를 선택적으로 유리하게 흡착하는 blue-rayon을 이용하는 현수법 및 column법으로 유기물을 흡착 추출하여, Salmonella typhimurium TA 98 및 TA 100에서의 돌연변이원성을 검색한 결과 다음과 같았다. 1. 흡착 유기물량은 8월이 11월에 비하여 약 1.7배 높았고, 현수법과 column법에서의 차는 없었다. 2. TA 100 균주에서 돌연변이원성은 나타나지 않았다. 3. TA 98균주에서의 돌연변이원성은, S-9mix 첨가의 계가 S-9mix비첨가의 계보다 높았고, 11월이 8월보다 높게 나타났다. Column법이 현수법에 비하여 돌연변이원성은 예민하게 검출되었다. In order to evaluate the toxic effect of organic pollutants in aquatic environments, organic substances extracted from blue-rayon adsorbates in Kyimgan River with the hanging and column methods were assayed by the Ames Salmonella mutagenicity test. Amounts of organic extracts adsorbed with the blue-rayon hanging method and the blue-rayon column method were similar. The mutagenicity toward TA 100 strain was not shown. The mutagenicity toward TA 98 with S-9mix was higher than that without S-9mix. For the quantitative concentration of polycyclic aromatic hydrocarbons in water, it was shown that the blue-rayon column method was more efficient than the blue-rayon hanging method.

XML 기반 문서의 활용을 위한 문서 출력 시스템

유재우,박준서 崇實大學校 生産技術硏究所 1998 論文集 Vol.28 No.-

XML(eXtensible Markup Language) is designed to enable the use of SGML(Standard Generalized Markup Language) on the World Wide Web. XML retains many advantages of SGML such as extensibility, complex structure and validation. Additionally it have URL link feature on the WWW and StyleSheet function. So XML solved defects of fixed document structure in HTML and invalidating in documents increasing the capability of usage structrue in HTML and invaliating in documents increasing the capability of usage magnification, many research are being performed but, private application is an insufficiency state. In this thesis, we aim at increasing the use of XML documents as design and implement of WEB browser for XML and, processed to document at each processing level by using essential information, because XML documents have need to more processing than general HTML documents.

Batcher-Banyan형 ATM 스위치의 성능개선에 관한 연구

유재우,이원재 崇實大學校 生産技術硏究所 1994 論文集 Vol.24 No.-

The Moonshine algorithm is based on the Batcher-banyan concept, and it uses a three phase algorithm to avoid the output contention occuring when multiple cells are destined to the same output. It requires an internal speedup to perform the 3 phases during one packet time. If the data field of the full packet has lp bits, the switch fabric with N ports would have to be speedup by a fraction logN(logN+4)/lp of the speed of the input port(where, log base is 2). In this paper we propose a new algorithm which reduce the above speedup fraction required to (logN(logN+3)+1)/lp. We also give three variations of the above algorithm proposed for performance improvement of Batcher-banyan based ATM switchs. One is the enhencement of the Moonshine two phase algorithm by using the concept of the above algorithm proposed, another is of using a addional fabric to detect output contention and the other is of using multiple array of Batcher-banyan networks for multiporcessing.

This study was to examine the effect of isokintic exercise prescription on thigh functional activity and muscle blow flow velocity after anterior cruciate ligament reconstruction. Subjects were twelve male patients. Test group were classified into isokinetice exercise group(seven male) and physical therapy group(five male). Ioskinetic exercise group(I.E.G) was exercised six times a weeks for eight week by using the isokinetic exercise in kin-com. Physical therapy group(P.T.G) were devoted oneself to one's physical therapy. Thigh strength showed significant increase in I.E.G and P.T.G especially I.E.G showed high(p<0.000) increase of 226.7% (quadriceps), 115.8% (hamstrings) compare with initial activity ratio. Cross sectional area of thigh showed significant (p<0.0001) increase of 3.65% in I.E.G Blood flow velocity showed significant(p<0.0001) increase of -18.8% in of I.E.G during 8week isokinetic exercise. Correlation among each variable showed closely connected. According to this results. after anterior cruciate ligament reconstruction. isokinetic exercise prescription will selected adaption of angle velocity from middle speed to high speed according to activity of muscle function.

비주얼 Yacc

정호욱,유재우 崇實大學校 1999 論文集 Vol.29 No.1

Yacc is one of the general parser generating tool, which is widely used in the related art, and the most Unix operating system has provided the same as a basic program. The Parser is used for checking syntatic and sementic error in a text. However, since a conventional parser generating tool which is used for generating the parser is to provide the text orient generating environment, a user have been inconvenient in using the tool. Further, a user has been required to get a knowledge relative to a complier and a programming language in constructing a grammatical portion. Thus, in view of the foregoing, the object of the present paper is to remedy the disadvantages of the conventional parser generating tool and to allow a user to easily generate the parser. To accomplish the above object, the present paper suggests that the grammatical portion is easily constructed by a visual component, and the constructed grammatical portion is error-processed in an interactive manner, therby allowing a user to easily process errors.

점진적-LR 파서 생성기

송후봉,유재우,김상헌 崇實大學校 生産技術硏究所 1993 論文集 Vol.23 No.-

Recent efforts on syntax-directed programming systems have shown the incremental parsing technique is basic and essential part of the system. We extended a conventional LR Parsing table to accept nonterminal symbols as well as terminal symbols, and also to accept incomplete sentences as input string. We use a parse tree to store the parse sequence and to retrieve previous parse sequence. With the extended parsing table and incremental parser driver, we can generate an efficient incremental parser automatically.

아이콘 지향 시각 언어에 관한 연구

송후봉,유재우,서봉수 崇實大學校 生産技術硏究所 1991 論文集 Vol.21 No.-

In contrast to text-oriented language, visual language uses high-level visual representations in programming. The visual representations also take charge of important part of messages. This paper study on design and implementation of the icon-oriented visual language. In the study, we have suggested formal method which interprets visual sentences and developed-interactive environment being able to communicate user with icon.
