Characteristics of carbon soot particles generated in diffusion flames were studied. Non-sooting and sooting normal diffusion flames using propane or ethylene as fuel were selected. In the flames, soot volume fraction was measured by a thermocouple, and primary particle diameter and cluster size were analyzed by TEM photographs. The characteristics of soot particles depended on flame(non-sooting or sooting) and fuel(propane or ethylene) type. Unlike the sooting diffusion flames, particle growth and oxidation processes were clearly observed in the non-sooting diffusion flames. In the sooting diffusion flames, soot particle size was slightly changed at the flame tip.

We report 2 cases of eosinophilic pustular folliculitis, one in s 29-year-old woman and the other in a 24-year-old man. Crops of papules and pustules developed on well demarcated, walnut-sized, erythematous plsques on the cheeks and forehead. Eruptions were more pronounced on the periphery of the plaques with central clearing. Blood eosinophilia was evident in case 1. Histologic findings showed a dense inflammatory infiltration and abscesses composed mainly of eosinophils in and around hair follicles, sebaceous glands and around blood vessels. We could see beneficial responses by administration of dapsone in both cases, but its effect was just suppressive and temporary.

Serious inherent problems with practicality, intra-rater and inter-rater reliability overshadow the known positive washback effects of performance assessment in language education. In particular, it has been welldocumented that inter-rater reliability poses a serious threat to overall test validity, since individual raters necessarily measure performance according to their own subjective severity criteria in language proficiency. However, language testing has witnessed a remarkable series of breakthroughs in performance assessment during the recent advent of the information era. One such breakthrough utilizes state-of-the-art automatic speech recognition (ASR) technology for oral proficiency interviews(OPI). Granting that current forms of ASR technologies may not produce results with the reliability needed to accommodate highstakes standardized test administration, they do offer aid in approaching the thorny issues of practicality and inherent human inter-rater subjectivity. Accordingly, this paper is intended to investigate the degree to which ASR-based OPI ratings match similar human-conducted OPI ratings by employing correlational analyses on the basis of degrees of rater severity. Furthermore, this paper attempts to explore a method of enhancing the robustness of ASR-based OPI ratings which capitalizes on suprasegmental information by measuring fluency based principally on the test-takers’ response time length.

The main problem of current ceramic tourist folk-craft Goods in Kyungju area is lack of local character in the products. To solve this problem, it is needed to make it characterized, and increase locality in products through symbolizing the local character. 1. This study explores the problems of manufacturing shops and products through the examination of the present conditions. 2. The purpose of this study is to present some suggestions for how to apply the local characteristic materials to the development of product design by finding out them from folk and cultural legacies.

본 연구에서는 고압전동기 고정자권선 진단데이터 분포특성 연구에 관하여 논하고 있다. 현장의 여러 환경에서 사용된 고압전동기 고정자 권선 절연진단데이터를 수집하였으며 와이블 해석을 통하여 사용환경에 따른 평균값을 산출하였다. 비교분석결과 제작사별로 전체의 진단항목 중 최대 11배의 차이가 났으며, 부하종류별 비교에서는 최대 2.5배의 차이가 발생하였음을 알 수 있었다.
