The noise emitted from construction machinery has long been a cause of environmental disputes, especially to the nearby residents. In 2008, the Ministry of Environment adopted the construction machinery noise labeling system to encourage the development of the low noise construction machinery. After the implementation of the noise labeling system of the construction machinery, the noise emitted from the construction machinery has been decreased over the six years. But, as the quality of life improves, a growing number of people desire more comfortable and quite living environment. Under the situation, new systems like the low noise labeling system are considered to encourage the development of the low noise construction machinery. In accordance with the low noise labeling system, the construction machinery satisfying the standard of low noise are qualified to attach the low noise label in front of the products. Thus, the product qualified the low noise certification will be incentivized by the choice of the consumer. In this paper, we have studied the necessity of the low noise labeling system for the construction machinery and the considerations to adopt the low noise labeling system of construction machinery. And we have studied appropriate criterion to judge the low noise construction machinery. The considerations studied in this paper will be helpful to adopt the low noise labeling system of construction machinery in the future.

본 논문에서는 구조화된 웹문서에서 자동으로 정보를 추출하고 추출된 정보를 통합하는 정보추출 시스템을 제안한다. 제안한 시스템은 레이블(label)이 없는 엔티티를 인식하기 위해 확률 기반 엔티티 인식 방법을 이용하며, 추출된 데이터를 이용하여 기존의 도메인 지식을 반자동으로 확장하는 기능을 제공한다. 게다가 기본 페이지에 링크된 하위 링크의 정보를 추출하는 기능을 제공하며, 도메인에 대한 이종의 정보 소스로부터 얻어진 유사 추출 결과를 통합하는 기능을 제공한다. 실험 결과, 도메인 지식만을 이용하여 웹 정보추출 시스템을 평가하였을 경우의 성능에 비해 하위링크의 정보를 추출하거나 확률 기반으로 레이블을 추론하여 추출 시스템을 평가한 경우의 성능이 상당히 향상됨을 보인다. 아울러 본 논문에서 제안하는 웹 정보추출 시스템은 도메인별로 시스템을 융통성 있게 적용시킬 수 있기 때문에 보다 다양한 정보들을 추출할 수 있다. 자동 도메인 지식의 확장이나 확률적 엔티티 인식 방법은 도메인 지식을 이용하는 프로그램이 추출할 수 있는 정보의 질을 증대시키기 때문에, 사용자의 만족도를 극대화시킬 수 있다는 장점이 있다. 따라서 본 시스템은 인터넷상의 영화 사이트나 공연 사이트 혹은 음식점 사이트에 대해서 정보를 추출해서 사용자의 지적 호기심을 충족시켜줄 수 있을 뿐만 아니라, 다양한 비교 시스템을 구축할 수 있기 때문에 전자 상거래의 활성화에도 기여한다.

The purpose of the study is to investigate the actual conditions of ready-to-wear Hanbok and is to establish the standard sizes for the women's ready-to-wear Hanbok. Twelve ready-to-wear Hanbok shops were investigated for the actual survey. Body measurements were taken from May to June, 1990 from 329 female college students living in the Seoul and Buchon. The ages of the subjects were 18"26. Thirty seven measurements were taken from each subject and analized for the results. Data were analized by factor analysis, and regression analysis. The results were as follows ; 1. As a result of the actual survey, the situation of the quality label was not enough. The size classification was not unified, and was not trusted statistically, it cannot satisfied consumers. 2. Factor analysis identified the two dimensions of body measurements 1 one was relevant to the height measurements including stature and to the length measurements of limbs, and the other was relevant to the trunk girth measurements and the limbs girth measurements. 3. because of plane construction of Hanbok, employed in this thesis was bl-dimensional sizing system using two controle dimensions including height factor(stature) and girth factor(bust girth) . 4. The Multiple regression formula was developed for estimating secondary dimensions of Hanbok Construction, in which stature and bust girth were posited as independent variables. 5. As a results, about 88.6371 of expected distribution were covered by 9 sizes, which were used as the basis for defining sizing system for Hanbok construction.tion.

This study was conducted to estimate the shelf-life of Kimbab manufactured using a Hazard Analysis and Critical Control Point (HACCP). We performed a microbiological verification after applying the HACCP plan to Kimbab. Additionally, the shelf-life of Kimbab at each holding temperature was calculated as a regression equation between the aerobic plate counts and holding time during the storage period. The critical control points of the HACCP plan, that were applied to Kimbab, included: cold-holding of refrigerated foods, checking the endpoint cooking temperature of heated food, and cold-holding of cooked foods. As a result of the microbiological verification of Kimbab, the aerobic plate counts averaged 3.46 log CFU/g. In contrast, the coliforms, E. coli, Staphylococcus aureus, and Salmonella spp. were not detected in any of the samples. The estimated shelf-life of Kimbab was calculated to be 45 hours at $10^{\circ}C$, 29 hours at $15^{\circ}C$, 6 hours at $25^{\circ}C$ and 3 hours at $35^{\circ}C$. In conclusion, manufacturers should apply a prerequisite program and a HACCP system for a safe consumption of ready-to-eat foods and label products with a proper shelf-life. Distributors should control the proper holding time-temperature until sale and consumers should eat immediately after purchasing ready-to-eat foods.

Although nano materials are used a lot in industries, there has not been any standard nano hazard graphic symbol. An experiment was conducted to know the comprehension ratio of newly designed eight nano graphic symbols. To compare the symbols with existing safety graphic symbols, other sixteen symbols were also included. 54 subjects evaluated the difficulties of graphic symbols on seven point Likert scale and answered the meaning for each symbol. The all eight nano safety symbols marked under 30% comprehension ratio. However, one of them didn't show any statistically significant difference with other existing safety symbols as like bio hazard, radiation, and laser. Therefore the nano symbol tested in the best could be adopted as the nano safety graphic symbol if it is sufficiently exposed in training period and used with warning label. The workers in industries using nano materials can be alerted and protect themselves where the sign is attached.
