오늘날 인터넷은 우리 생활 전반적인 모든 분야에서 활용되고 있다. 인터넷을 이용할 때, 사람들은 구글, 야후 등 검색엔진을 이용하여 검색하고 원하는 결과를 얻어간다. 이에 따라 자신들의 웹 사이트를 광고 등의 목적으로 검색엔진 상위에 노출시키려는 웹 스팸이 대두되고 있다. 웹 스팸은 검색엔진에서 본래 받아야하는 랭킹보다 더 높은 랭킹을 받기위해 여러 가지 방법을 사용한 악의적인 웹 문서들을 말한다. 웹 스팸은 검색엔진의 전반적으로 성능 저하를 초래하므로 반드시 해결되어야 한다. 검색 알고리즘에서 링크 구조의 중요도가 높아짐에 따라 검색 결과 상위에 노출되는 웹 스팸을 탐지하기 위해선 링크 스팸을 필터링할 수 있어야 한다. 그래서 인덱싱 단계에서 검색 결과 상위에 나오는 웹 스팸을 필터링하기 링크 스팸 중 Link Farm과 Link Exchange를 탐지하기 위한 모듈을 제안, 설계, 구현하고 검증하였다.

사용조건에 따른 건물 냉난방 부하 변화에 관한 연구

이찬범 서울과학기술대학교 2020 국내석사

건물에서 에너지의 소비는 실외온도에 밀접하게 연관되어 있어서 더운 여름과 추운 겨울에 소비량이 증가한다. 또한 재실인원과 냉난방 설정온도, 침기횟수, 제어방식의 변화에 따라서 냉난방 부하가 변화할 수 있다. 건물에서 냉난방부하 변화에 따른 에너지소비를 저감하기 위해서는 실제 건물을 선택하여 실험하는 방법과 시뮬레이션을 진행하는 방법 중 하나를 선택하여야한다. 실제 건물을 선택하여 실험하는 방법은 시간과 장소, 비용 측면에서 제한적이기 때문에 실제건물을 모델링하고 냉난방부하에 영향을 미치는 여러 가지 변수를 고려하여 시뮬레이션을 진행하고 냉난방 부하를 비교하여 분석하면 에너지소비의 저감이 가능하다. 본 연구에서는 TRNSYS를 이용하여 건물에서 재실인원의 변화, 냉난방 설정온도의 변화, 시간당 침기 횟수에 대한 변화, 제어방식 변화에 따른 냉난방 부하 변화를 시뮬레이션하고 얻어진 결과에 대해 변수와 냉난방 부하 사이 관계를 비교하였다. 재실인원은 최대수용인원과 임의로 설정한 약55% 비율로 평균인원을 산정하였다. 냉난방 부하는 외기온도와 주변 조건의 영향을 받으며. 재실인원이 많을수록 냉난방 부하는 높아지게 된다. 4가지 조건에서 한 개씩 변경해가면서 시뮬레이션을 진행하였으며, 냉난방 설정온도는 공조기로 설정 가능한 최소 냉난방온도에서 최대 냉난방온도까지 정하여 설정 온도에 따른 각각의 냉난방 부하량과 총 부하량을 계산하였다. 침기는 실내외 공기압차이로 인하여 발생하는 의도되지 않은 환기현상이므로 시뮬레이션 내에서만 설정이 가능하다. 냉난방 부하 비교를 위해 필요한 침기 횟수는 임의로 설정하고 부하 계산을 진행하였으며, 침기 횟수가 증가할수록 외기의 영향으로 인해 냉난방부하는 상승하였다. 재실인원은 0~100명까지 10명단위로 냉난방 부하를 계산하였으며, 인원이 많을수록 냉방부하는 증가하고 난방부하는 감소한다. 총 부하는 감소하다 증가하는 경향이 나타나는데 공간대비 최대허용인원과 관계가 있는 것으로 분석된다. 제어방식에 따른 부하의 비교를 위하여 ON/OFF 방식과 PID 제어방식을 선택하여 비교하였다. ON/OFF 제어방식은 설정점전까지 작동하고 설정점에 도달하면 정지하는 방식이다. PID제어는 비례, 적분, 미분을 조합하여 제어하는 방식이다. 제어하고자 하는 대상의 출력 값을 측정하여 설정점과 비교하여 오차 값을 계산하고 제어 값을 결정한다. 제어변수 설정이 ON/OFF 제어방식에 비하여 어렵지만 더 세밀한 제어가 가능하다. 두 제어방식으로 시뮬레이션을 진행한 결과에서 부하의 차이가 근소하게 나타났다. 결론적으로 재실인원, 냉난방 설정온도, 침기 횟수에 따라서 냉난방 부하의 차이가 발생하는 것으로 나타났으나, 제어방식의 변화에 따른 냉난방 부하의 차이는 근소한 것으로 나타났다. The consumption of energy in buildings is closely related to the outdoor temperature, which increases in hot summer and cold winter. In addition, the load on heating and cooling may change depending on the number of occupants, the set temperature of heating and cooling, the number of infiltrations, and the control method. In order to reduce energy consumption due to changes in heating and cooling loads in a building, one of the methods of selecting and experimenting with an actual building and conducting a simulation must be selected. Since the method of selecting and experimenting with a real building is limited in terms of time, place, and cost, modeling a real building, conducting a simulation considering various variables affecting the heating and cooling loads, and comparing and analyzing the heating and cooling loads will result in reduction of energy consumption. In this study, TRNSYS is used to simulate changes in the number of occupants in a building, changes in heating/cooling set temperature, changes in the number of infiltrations per hour, and changes in cooling and heating loads due to changes in control methods, and compares the relation between variables and heating and cooling loads for the results obtained. The average number of occupants was calculated by the maximum number of people accommodated and the ratio of about 55% arbitrarily set. Heating and cooling loads are affected by ambient temperature and ambient conditions. The greater the number of occupants, the higher the heating and cooling load. The simulation was performed by changing one by one under four conditions, and the heating/cooling set temperature was determined from the minimum cooling/heating temperature that can be set with an air conditioner to the maximum cooling/cooling temperature, and each cooling and heating load and total load according to the set temperature were calculated.. Invasion is an unintended ventilation phenomenon caused by the difference in air pressure between indoors and outdoors, so it can be set only within the simulation. In order to compare the heating and cooling loads, the number of invasion required was arbitrarily set and load calculation was performed. As the number of infiltration increases, the air conditioning load increases due to the influence of outside air. Cooling and heating loads by the number of occupants in the room was calculated from 0 to 100 people in 10 people, and the cooling load increases and the heating load decreases as the number of people increases. The total load decreases and tends to increase. It is analyzed that it is related to the maximum allowable number of people in space. For comparison of load according to control method, ON/OFF method and PID control method were selected and compared. The ON/OFF control method operates until the set point and stops when the set point is reached. PID control is a method of controlling proportional, integral, and differential combinations. Measure the output value of the object to be controlled and compare it with the set point to calculate the error value and determine the control value. Control variable setting is more difficult than ON/OFF control method, but more precise control is possible. In the simulation result of the two control methods, the difference in load was slight. In conclusion, the difference in air-conditioning load occurs depending on the number of occupants, the set temperature of heating and cooling, and the number of infiltrations, but the difference in cooling and heating load according to the change of control method was found to be slight.

大學의 社會敎育 프로그램에 대한 地域住民의 期待에 관한 硏究 : 忠淸北道를 中心으로

이찬범 建國大學校 社會科學大學院 1999 국내석사

The purpose of the study The colleges have attached importance to regular education for students until now according to national education policies and conditions, but from now on they have to serve lifelong learning opportunities and expand social service activities at the same time for local residents. Therefore, colleges have to establish programs according to expectations of local residents, and the purpose of this study is to show the direction of social education for the development of universities through them. The method of the study I distributed 500 questionnaires to the students in 4 social education institutes in colleges and 2 other common social education institutes, and analyzed the contents of 303 questionnaires which were collected finally. The contents of the questionnaire was firstly divided into two categories of participants and non-participants, and nextly, participants were analyzed in the order of: ① the response to the college social education programs ⑦ the comparison of the social education programs of college and other common institutes ③ the expectation details on college social education programs. Non-participants were asked their opinions about the program of common social education institutes and the fields they want to participate among the programs. The result and analysis of the study The first motive of participation in college social education is 'the necessity of self-development', and the purposes of participation are 'acquisition of professional knowledge', 'interest activity', 'acquisition of liberal arts', and other various things. When I analyzed the responses from the participants who participated both social education institutes, they responded that the programs of both institutes are similar in the respect of the program construction, the quality of instructors, the education and convenience facilities, and the professionality of educational contents, which tells the need of specializing and differentiating college social education programs. They think 'specialization of education contents', 'diversity of programs', 'quality of instructors' as the merits of college social education programs, while 'low tuition fee' as the biggest merit of common institutes. But it is not meaningful to say 'college social education is better' when there exist very few common social education institutes which can be compared with colleges about their educational conditions, that is, it can be said that college social programs have not been specialized yet. Concerning the expectation details from the participants on college education, the local residents want conducting method and programs to be related to local community, therefore we have to consider that problem positively in a community school position. The difference from the previous studies while previous studies were conducted only through literatures or about college social education programs, this study compared the programs of college social education institutes and other common social education institutes, and then present the problems of social education which is being conducted in colleges.
