효율적인 이벤트 데이터 전송을 위한 이벤트 필터링 채널의 설계

채영진(Young-Jin Chae),노희영(Hee-Young Roh) 한국정보과학회 2002 한국정보과학회 학술발표논문집 Vol.29 No.1A

현재 클라이언트/서버 네트워크 환경은 시스템이 점점 대형화되면서 유지보수 및 네트워크 트래픽에 대한 문제로 인하여 분산 객체 개념을 이용한 분산 환경의 페러다임이 필요하게 되었다. 이에 OMG의 CORBA는 분산 환경을 위한 표준을 제공하며, 분산 객체간의 비동기 호출을 위한 이벤트 서비스를 명시하고 있다. 분산 객체간의 데이터 전송은 전체 시스템의 성능을 좌우하는 중요한 요인으로 평가받고 있으나 이벤트 서비스는 이벤트 데이터를 위한 필터링 기능을 제공하고 있지 않아 비효율적인 데이터 전송을 하고 있다. 본 논문에서는 이벤트 채널의 필터링을 위한 모듈을 정의하여 기존의 서비스에서 제공하는 이벤트 채널보다 효율적인 데이터 전송이 가능한 이벤트 필터링 채널을 설계한다.

전자메일은 사용의 편리성과 정보전달의 신속성 때문에 널리 사용되고 있지만, 광고목적이나 악의성을 갖는 스팸메일의 양도 증가하여 사회적 경제적으로 큰 문제를 야기한다. 스팸메일을 필터링하기 위한 방법은 수용 전 단계와 수용 후 단계로 나누어서 접근할 수 있는데, 수용 후 접근의 경우는 메시지로부터 단어나 문장 단위로 자질을 추출하고 그로부터 학습이나 매칭방법을 통하여 필터링을 하는 과정을 포함한다. 하지만, 필터링을 우회하기위해 스패머는 계속적으로 단어를 변형시켜 메일을 발송시키고 있다. 특히 한국어의 경우는 특성상 한 음절을 이루는 음소의 변화로부터 변형이 가능하기 때문에 그 변칙적 사용이 더 다양하다고 할 수 있다. 따라서, 기존의 정규식이나 학습알고리즘은 대처에 한계를 갖게 된다. 이에 본 논문에서는 한글의 변칙어를 인식할 수 있는 방법을 제안함으로서 스팸메일분류 시스템의 성능을 향상시키고자 한다. 이를 위해, 자소접근방법을 사용하고, Smith-Waterman알고리즘을 적용하였다. 메일서버로부터 추출한 필터키워드와 메일로부터 제안한 방법을 실험한 결과 유사도 수준에 따라 한글 변칙어들을 정확히 인지해 낼 수 있었다. 실험을 통해 소요 공간 및 시간은 허용될 수 있는 수준임을 확인하였다. As electronic mails are being widely used for facility and speedness of information communication, as the amount of spam mails which have malice and advertisement increase and cause lots of social and economic problem. A number of approaches have been proposed to alleviate the impact of spam. These approaches can be categorized into pre-acceptance and post-acceptance methods. Post-acceptance methods include bayesian filters, collaborative filtering and e-mail prioritization which are based on words or sentances. But, spammers are changing those characteristics and sending to avoid filtering system. In the case of Korean, the abnormal usages can be much more than other languages because syllable is composed of chosung, jungsung, and jongsung. Existing formal expressions and learning algorithms have the limits to meet with those changes promptly and efficiently. So, we present an methods for recognizing Korean abnormal language(Koral) to improve accuracy and efficiency of filtering system. The method is based on syllabic than word and Smith-waterman algorithm. Through the experiment on filter keyword and e-mail extracted from mail server, we confirmed that Koral is recognized exactly according to similarity level. The required time and space costs are within the permitted limit.

Depending on the career path chosen by an individual, the individual's social and economic status as well as his values, abilities, and level of experience are influenced by all aspects of life. It is important that the beauty profession is also competitive with technical professions, away from simple beauty functions. Although the beauty industry is making great progress, there is a problem of labor imbalance between demand and supply in the labor supply part to support this. Therefore, this study aims to provide a more concrete and systematic way to pursue a career direction for students related to beauty education, and to provide basic data on effective education methods for educating talented person who is ultimately a professional beauty.The research of the study targeted students in Seokyung University, the current beautician, and a beauty academy in Gyeonggido. A total of 450 copies of a total of 470 copies above, with a valid questionnaire of 430 copiesIt was used as a final analysis material by using the statistics. The effects of self - efficacy on academic achievement and career decision, and the effect of academic achievement on career decision, showed that task solving ability and self - confidence had a statistically significant effect on academic achievement. It was found that there was a statistically significant effect on the sub-factors, planning and goal selection. In addition, the analysis of the mediating role of academic achievement in the relationship between self - efficacy and career decision showed that the mediating effect of academic achievement was statistically significant, and the analysis of the mediating role of academic achievement in the relation of self - effiacy The mediating effect of. It is necessary to make individuals aware of emotional, material, and valued support for others while fostering confidence that they can successfully fulfill the demands of various situations in relation to career. Based on the results of this study, we plan to improve the self-efficacy of the students who are preparing for career, and hope to be used as educational material for a more concrete and systematic career direction.

A survey of 325 men and women aged from the 20s to 40s who were mostly skin care and hair design majors living in Seoul and Gyeonggi Province was conducted from June 21 to July 30 of this year and the result was used for statistics. A course of ‘acquisition of working techniques' (42.5%) was considered the most important lesson for Department of Cosmetology out of ways to improve cosmetology education courses but there were no significant differences according to majors (p>.05). About 31.1 percent of the respondents replied that ‘4:6’ is the most appropriate ratio between theory and training courses and there weren’t significant statistical differences according to majors (p>.05). Up to 91.1 percent thought that major segmentation (intensive learning) and there were no significant statistical differences according to majors (p>.05). Regarding the most appropriate time for starting major segmentation (intensive learning) , 33.1 percent of the respondents answered the first term of the third school year at four-year courses and there were significant differences according to majors (p<.05). Up to 48.0 percent of the respondents chose the first term of the second school year in two-year courses and there were significant statistical differences according to majors (p>.01).

This study aims to investigate the characteristics of particular matter generation factors in office settings by analyzing the characteristics of particular matter generation according to the hourly usage of office equipment and the equipment usage pattern. The experiment was conducted from November 10th at NLandscape Office; inkjet printer and document shredder were selected for analysis among particular matter-generating factors in the office. In order to control the experiment environment, A particular matter indicator (SIBATA’s LD_5KR) was used to measure particular matter. Measurements were performed 10 times for each equipment, and the minimum, maximum, and average values were calculated. Also, changes of particular matter measurement values according to usage pattern for each equipment were examined during the measurement. According to the results, inkjet printers basically generated fine dust when there was an action, and a higher number ‘when collecting printed materials’ occurred than ‘paper jam’. As the usage behavior occurred and the frequency of occurrence increased, the total amount of particular matter increased. This was the same in the case of document shredders. The result of this study is expected to be the basic data for establishing the standards and guidelines that can help to reduce the particular matter in the office by analyzing the usage pattern of the office equipment.
