Objective : An adequate measurement for Atopic Dermatitis(AD) is essential for studies about the treatment of AD. To establish a new and adequate scoring system for AD in Korean medicine, we reviewed existing studies on AD outcome measurement in Korean medicine. Method : We searched for reviews on measurements of AD or studies which used an AD outcome measurement at the Korean Traditional Knowledge Portal from 1995 to June, 2008. And then we reviewed the pattern identification in AD patients and the outcome measurements for AD in each study. Results : 1. Among 25 studies, the most common measurement for AD was SCORAD(the severity SCORing of Atopic Dermatitis index), there were 16 studies. There was one study which used the Jakob T scoring system, one study which used ADSI(the Atopic Dermatitis Severity Index), and there were 7 studies which established or used a new severity scoring system for AD. 2. In Korean medicine, AD caused by Damp-Heat is accompanied by erythema, papulation, oozing and crust, Damp-Heat accompanied by Spleen-Gi deficiency is frequently found in pediatric patients, and in adults who have indigestion. Symptoms of AD caused by blood deficiency and Wind-Dryness include lichenification, dryness, scale and pigmentation. AD caused by toxic Heat in the blood system has symptoms similar to some Damp-Heat pattern along with symptoms of blood deficiency and Wind-Dryness. Conclusion : We need to establish a new severity scoring system which reflects pattern identifications and treatments with Korean medicine, and we should assess the validity, reliability, and sensitivity of the new scoring system.

Although the frequency of use for community facilities in rural villages is growing as well as the importance of the facilities for urban-rural exchange is being highlighted, study on spatial location-analysis of the facilities for such multi-purpose is not so much. This study aims to find the spatial distribution forms of community facilities in rural villages such as community center and rural-pocket park through location-analysis, in order to provide available data for selecting location in the future. As the study area, Sojeong-myeon, Sejong Special City was selected. This study conducted GIS analysis for criteria of the location-evaluation model developed in this study. This study introduced the concept of time-distance for accessibility analysis. This paper also used linear-consecutive scoring method(LCSM) as a scoring method of criteria and Analytic Hierarchy Process(AHP) method for weighting values of criteria. The application results showed that the new model can generate the intensity of community facilities according to spatial distribution and accessibility from cities to the facilities.

From the mid-1990s in Korea, performance assessment has been continuously emphasized in school mathematics and thus many researchers and teachers have been steadily studying this topic. But the concepts relevant to performance assessment and its purposes are very confusing because the mathematics educators' different views and voices are vary. As a result most mathematics teachers experience trouble in executing performance assessment properly and effectively in their math class. This unability for proper execution of performance assessment was once again revealed in this study which dealt with 15 articles on performance assessment. These 15 articles includes almost every article written on the topic of performance assessment that have been published in 4 domestic journals since December 1997. By examining this inability, it is required that its concepts and purposes should be organized with a common view and newly defined in the near future. Therefore, to successfully accomplish this, this paper outlines the basic problems on the understanding of performance assessment as follows: ㆍWhat is the relationship between performance assessment and alternative assessment\ulcorner ㆍWhat is the proper types(methods) of performance assessment\ulcorner ㆍIs the subject test a type of performance assessment\ulcorner ㆍWhat is the difference between subject test and essay test\ulcorner ㆍWhat is the relationship between performance assessment and performance tasks\ulcorner ㆍWhat is the relationship between performance tests and project method\ulcorner ㆍWhat is a project method\ulcorner ㆍIs it assessment standard or scoring standard to score a test result\ulcorner ㆍWhat is the difference between analytic scoring method and holistic scoring method?

Aim: To evaluate the differential diagnostic potential of lesion stiffness assessed by the sonoelastographic strain index ratio (SR) and elastographic color scoring system (UE) for breast lesions. Materials and Methods: Three hundred and forty two breast masses (158 benign and 184 malignant) from 325 consecutive patients (mean age 44.2 years; range 16-81)who had been scheduled for a sonographically guided core biopsy were examined proposed by Itoh et al, with scoring 1-3=benign and 4-5=malignant. Strain and area ratios of each lesion were calculated within the same machine. Histological diagnosis was used as the reference standard. The area under the curve (AUC) and cut-off point were obtained by receiver operating curve and the cross table Fischer Test was carried out for assessing diagnostic value. Sensitivity, specificity, PPV, NPV, accuracy and false-discovery rates were compared. Results: The mean strain ratios for benign and malignant lesions were 1.87 and 7.9 respectively. (P<0.0001). When a cutoff point of 3.54 was used, SR had a sensitivity of 94.6%, a specificity 94.3%, a PPV of 95.1%, an NPV of 93.7% and an accuracy of 94.4%. The AUC values were 0.90 for the 5 point scoring system (UE) and 0.96 for the strain index ratio. The overall diagnostic performance was SR method was better (P<0.05). Conclusions: Strain ratio measurement could be another effective predictor in elastography imaging besides 5 the point scoring system for differential diagnosis of breast lesions.

We propose a new method for automatic fluency scoring of English speaking tests spoken by nonnative speakers in a free-talking style. The proposed method is different from the previous methods in that it does not require the transcribed texts for spoken utterances. At first, an input utterance is segmented into a phone sequence by using a phone recognizer trained by using native speech databases. For each utterance, a feature vector with 6 features is extracted by processing the segmentation results of the phone recognizer. Then, fluency score is computed by applying support vector regression (SVR) to the feature vector. The parameters of SVR are learned by using the rater scores for the utterances. In computer experiments with 3 tests taken by 48 Korean adults, we show that speech rate, phonation time ratio, and smoothed unfilled pause rate are best for fluency scoring. The correlation of between the rater score and the SVR score is shown to be 0.84, which is higher than the correlation of 0.78 among raters. Although the correlation is slightly lower than the correlation of 0.90 when the transcribed texts are given, it implies that the proposed method can be used as a preprocessing tool for fluency evaluation of speaking tests.

As a basic study to clarify the scoring resistance in lubricated sliding contact, the temperature rise on frictional surface was analyzed by theoretical method and the effects of various factors on the temperature rise were examined. On the basic of the results obtained theoretically, the practical equations to calculate the maximum average temperature of the contact surface were proposed which are applicable to sliding contact. Then, the effects of sliding velocity and oil temperature on the seizure behavior, and the relation between seizure and temperature rise were investigated. The following conclusions are deduced : The maximum average temperature rise and the other bulk temperature. The former is affected by the size of heat supply region and the sliding velocity, the latter is affected by heat transfer coefficient. Without regard to the operating condition such as sliding velocity, oil temperature and operating time at each load-step, the maximum average temperature just before seizure is nearly constant except in the region of lower velocity. Consequently, the maximum average temperature of the contact surface in boundary lubrication is a useful criterion to predict the scoring of sliding contact.

직접측정이 불가능한 단일 상위목표개념을 직접측정이 가능한 관련 하위개념들을 이용하여 간접적으로 측정한 경우, 많은 연구자들이 비록 모호하나마 연구초기에 이해했던 목표개념과 관련개념들간의 관계를 자료분석의 단계에서 구체화하지 못하고, 목표개념의 점수화를 편의성에 의존한다거나 통계분석자에게 일임해 버리는 경향이 있다. 그러나 사용된 점수화 방법에 대한 객관성이 결여되면 그릇된 정보가 도출되거나 연구결과가 독자들로부터 수용되어지지 못할 수도 있다. 본 연구에서는 이러한 상황에서 측정이론에 충실하면서 목표개념의 조작적 정의를 어느정도 객관화할 수 있는 한 방법을 제안하고, 이에 바탕을 둔 대표성분점수화법의 타당성 및 활용성에 관해 연구하였다.
