In order to evaluate the exact effect of detergency it is necessary both to measure the actual soil content by chemical analysis and to determine the degree of soil removal visually. Since it takes considerable time and effort to use both methods, usually one of the two methods is used. Many studies have been carried out through increasing the visibility of oily soil to evaluate detergency by measuring reflectance of fabrics. In this study Sudan Black B, an oil soluble dye was used as an indicator to increase the visibility of oily soil on cotton and polyester fabrics. The condition of artificially soiled fabrics and the method of evaluating detergency were investigated which represent the actual detergency of oily soil by measuring the reflectance only. Also the detergency of Sudan Black B and that of oily soil were compared with each other under various washing conditions, As a result, the K/S values converted from the reflectances showed a good correlation with the actual soil content. Linear relationship between K/S value and the actual soil content was obtained. The K/S values of washed fabrics were higher than those of unwashed fabrics which included same content of soil since the soil visibility changed during washing. But the difference was small when Sudan Black B was used. With the increase of soil content, detergency of cotton fabric decreased, but detergency of polyester fabric increased gradually. With regards to soiled fabrics, detergency of cotton fabric measured by K/S value was close to that of actual oily soil when Sudan black B was used as an indicator.

교량의 내하력을 평가할 때 수행되는 구조해석은 재하시험을 통한 구조물의 실제거동과 유사한 거동특성을 구현하여야 되나 지점의 거동특성, 구조해석시 모델링 방법, 재하시험의 오류, 단면손상에 따른 강도 및 강성변화 등으로 인해 그렇지 못하는 경우가 있다. 특히, 교량받침이 손상하였거나 설치되지 않아 받침의 기능수행이 미비한 교량에서 이를 고려하지 않고 일률적으로 모델링을 하는 경우에는 이러한 문제가 더욱 심화될 수 있다. 본 연구에서는 단일보의 내민구간을 구속시켜 얻어진 실측처짐($\delta$실측)과 비구속상태에서의 계산처짐($\Delta$계산)과의 차이값인 $\Delta{\delta}$으로부터 얻어진 지점모멘트를 구조해석모델에 작용시켜 실제거동과 유사한 해석결과를 얻었다. 이에 따라 실제 공용중인 교량을 대상으로 지점의 구속조건을 고려하여 내하력을 평가한 결과 기존 방법에 의한 내하력에 비해 15~19% 적게 평가되었다.

Wind energy has proven its viability by the emergence of countless wind turbines around the world which greatly contribute to the increased electrical generating capacity of wind farm operators. These infrastructures are usually deployed in not easily accessible areas; therefore, maintenance routines should be based on a well-guided decision so as to minimize cost. To aid operators prior to the maintenance process, a condition monitoring system should be able to accurately reflect the actual state of the wind turbine and its major components in order to execute specific preventive measures using as little resources as possible. In this paper, we propose a fault detection approach which combines cluster analysis and frequent pattern mining to accurately reflect the deteriorating condition of a wind turbine and to indicate the components that need attention. Using SCADA data, we extracted operational status patterns and developed a rule repository for monitoring wind turbine systems. Results show that the proposed scheme is able to detect the deteriorating condition of a wind turbine as well as to explicitly identify faulty components.

Objectives: The purpose of the study was to investigate the actual oral health status and dental fear level in the elderly. Methods: Data were collected by questionnaire interview method from June 15, 2013 to December 14, 2013. The subjects were elderly over 65 years old in Jeonbuk province. The study instrument was structured questionnaire including general characteristics of the subjects(3 questions), oral health management status(16 questions), Dental Fear Survey(DFS, 9 questions). Cronbach alphas were 0.804 and 0.959 in the study. Higher score of oral health management status showed good oral health care and higher DFS showed higher level of dental fear. Data were analyzed by t-test, one way ANOVA, post-hoc Scheffe test, and Pearson correlation analysis. Higher dental fear was defined below 33.3%. Results: Women tended to have better oral health than male. Women brush their teeth more frequently than male. Most of the elderly answered that it was important to brush teeth for 3 minutes, to use dental floss and to have oral health education(p<0.05). Score of dental fear level was similar in men and women. Those who were above 69 years old tended to have dental fear. Poor oral health condition was closely related to dental fear. Conclusions: The oral care in the elderly showed considerable differences between the groups and affected the dental fear. It is important to implement the nationwide dental care for the elderly in the future.

The corrosion forms of automotive body panels are various. One of the representations is a corrosion pitting and its propagation on the lapped portion by galvanic corrosion. But it has been difficult in correlation analysis about the corrosion propagation rate and mechanism of pitting and the actual automotive body in field. This present study interprets experimentally the rust pitting occurrence mechanism on the lapped panels through experimental methods. And field car investigation was executed for correlation analysis with experimental results. This paper compares corrosion propagation rate by pitting on hot-dip galvannealed steel sheets with corrosion forms in the automotive field condition. The research fundamentals which make it possible to predict the pitting occurrence and propagation on the lapped panels in the actual vehicles are given.
