As the uses of WWW are growing, the uses of internet and intranet are growing too. Many companies put into operation the computerization of job processing using the intranet. However, in the majority of the cases, intranets are limited by bulletins board, information floor and chatting room in the function. In this paper, internet shopping mall typed Procurement system based on intranet is designed and implemented.

High-Volume 플라이애쉬 콘크리트의 기포조직에 관한 연구

강수근,서완용,정철우,김영수 釜山大學校生産技術硏究所 2002 生産技術硏究所論文集 Vol.61 No.-

산업 부산물인 플라이애쉬를 사용한 콘크리트는 내부에 존재하는 다량의 플라이애쉬에 의해 발생하는 공극의 분화 효과에 의해 보통의 콘크리트와는 다른 기포조직을 가질 수 있다. 콘크리트가 동결작용을 받을 시 발생하는 수압을 완화할 수 있는 기포의 영향범위는 기포간의 거리에 의해 결정되며, 이것의 최대값이 기포간격수라고 불리고 있다. 본 연구에서는 High-Volume 플라이애쉬 콘크리트의 기포조직을 카메라를 통하여 입력된 화상의 데이터를 컴퓨터에 의해 정략적으로 처리하는 화상분석법을 이용하여, 연행공기량과 플라이애쉬 콘크리트의 공기량, 비표면적, 기포간격계수 등을 보통 콘크리트와 비교, 분석함으로서 High-Volume 플라이애쉬 콘크리트의 기포조직을 파악하고자 한다. The purpose of this paper is to investigate the air-void spacing factor of high-volume fly ash concrete. For this purpose, the air-void spacing factor of the hardened fly ash concrete was determined by image analysis method for a large number of parameters adjusting such as air contents and the rate of fly ash replacement. Based on the study of the test results, the following conclusions may be drawn. 1) As the rate of fly ash replacement for high-volume fly ash concrete increases, air contents decrease. Furthermore the air content is varied approximately 1 % before and after hardening. 2) As the replacement of fly ash increases, the spacing factor increases due to adsorption of air entraining agent. 3) As the air content decreases and the specific surface increases, the spacing factor of High-Volume fly ash concrete increases.

What are relatrve to Run-time of computer langurage for one another under the same sort algorithm and influence the time of sorting are divided into three parts. The first is the character of algorithm, the second is the character of computer system, and the third is the character of languages, and to find effective language under the same algorithm and same system. Each language has its own speed of sorting under same algorithm, same system and same data. Pascal is the fastest of all and Fortran is the next one. Cobol is the latest one among them because Pascal and Fortran approach the character of algorithm descriptive language, but cobol don't. Pascal and Fortran is good for algorithm language, but Cobol is not.

비압축성유체를 작동유체로 하고 뜨거운 흐름은 직렬이고 찬 흐름은 병렬로 된 이중관 대항류 열교환기에 대한 성능을 열역학 제1법칙적 관점과 제2관점에서 이론적 및 실험적으로 해석 하였다. 주어진 열교환기 형상과 입구조건에 대하여 펌핑동력에 대한 열교환량 및 엔트로피 생성율을 찬 흐름분율, 유량비열, 입구온도비에 대하여 계산하고 실험치와 비교하였다. 아울러 찬 흐름측을 직렬로 하였을 경우의 값들과도 비교하였다. The performance of the double pipe counterflow heat exchanger which uses an incompressible fluid as a working fluid and is connected in series on the hot side and in parallel on the cold side, was analysed both theoretically and experimentally in the view of 1st and 2nd law of thermodynamics. The ratio of heat transfer rate to pumping power and the rate of entropy generation for the given geometry of the heat exchanger and inlet conditions, were calculated and compared with the experimental results for the cold side fraction, the ratio of capacity rate, and the ratio of inlet temperatures of both sides. In addition, the ratio of heat transfer to pumping power and the rate of entropy generation were compared with those values of the case connected in series on the cold side.

내부 정렬에 관한 알고리즘들을 분석하고 PASCAL로 응용 프로그램화 하여 각 알고리즘들의 정렬 속도 및 효율성을 실험적 방법으로 비교 평가 하였다. 각 알고리즘에 대한 응용 프로그램의 수행결과를 요약하면 다음과 같다. 1. Straight Insertion sort는 초기상태의 입력자료가 순서배열 되어있는 경우와 소량의 데이터 화일에서 적용이 바람직하다. 2. Bubblesort는 실행시간이 가장 늦었으면 내부정렬 방법들 중에서 가장 비효율적이다. 3. Quicksort는 실행시간이 빨랐으며 내부정렬 방법들 중에서 효율이 가장 우수하다. 4. Heapsort는 실행 시간 면에서는 상당히 빠르지만 입력화일을 Tree로 구성하고 Heap성질이 유지되도록 재 조정이 필요하다. 5. Two-way Mergesort는 레코드의 길이가 길 경우에 레코드들의 이동에 걸리는 시간이 실행시간에 큰영향을 준다. The objects of this study is to investigate experimentely the sorting time and efficiency of internal sort algorithms. To generate sample data, We used the system's random-number generator. The experiments included both large and small samples of data with numeric keys. Table1 shows the sorting times(in milliseconds)consumed by the application programs of sort algorithms. as executed by the Turbo-Pascal system on a PRO-3000 computer. The results of experiments are as follows: 1. Bubblesort is definitely the wrost sorting method among all compared. 2. Quicksort has even strengthened its position as the quickest method and appears as the best array sorter by far.

In this study, the detail plants were analyzed by relating to the geographical configuration of the ground as using the basic data of the plants in the whole area of Mt. Obong and focusing on each detail space of the relics in the Zen garden of Cheongpyeongsa. Mt. Obong, which Cheongpyeongsa is located in, contains 434 different species of vegetation and the typical communities are of Pinus densiflola and Quercus mongolica. There are various types, a coniferous forest, a deciduous forest and a mixed forest. The typical landscape plants observed in the old literatures are Pinus densiflola, Pyrus ussuriensis and Taxus cuspidata. As the landscape plant maintained from the past, two trees of Taxus cuspidata, which have existed until now from the era of the Goryeo Dynasty, and Keria japonica for. plena, which is assumed that it had been planted in the beginning of the Joseon Dynaty, remain in the precincts, the Youngji and the Seocheon district.
