한국에서 가지 흰가루병균으로 Erysiphe cichoracearum, Leveillula taurica, Sphaerotheca fusca 모두 3종이 기록되어 있다. E. cichoracearum은 1969년에 기록된 이후 한국에서 발생하는 가지 흰가루병균으로 여긴다. 1998년에는 L. taurica가 가지 뒷면흰가루병균으로 기록 되었으나, 이후에 추가적인 발생기록은 없었다. 2002년에는 S. fusca가 가지 흰가루병균으로 보고되었다. 필자들은 총 22점의 가지 흰가루병균 시료를 채집하여 현미경 관찰 및 염기서열 분석을 실시하였으며, 그 결과 모두 Podosphaera xanthii로 동정하였다. 따라서 한국에서 가지 흰가루병균은 P. xanthii로 표기하는 것이 옳으며, 시설재배에서 드물게 발견되는 L. taurica는 뒷면흰가루병균으로 구별하는 것이 맞다. 반면에, E. cichoracearum (= Golovinomyces cichoracearum)은 가지 흰가루병균으로 표본이 보존되지 않았으며 이후에 채집되지도 않았다. 더구나 가지에서 기록한 E. cichoracearum의 기재는 일반적인 형태적 변이의 폭을 크게 벗어난다. 따라서 E. cichoracearum 흰가루병균의 존재에 대한 과거의 기록은 오류로 생각 된다. 결국 P. xanthii가 한국의 가지에서 발병하는 흰가루병의 주요 병원균으로 판단되며, L. taurica는 드물게 발생되었던 것으로 판단된다. 이 총설에서는 가지 흰가루병균의 역사와 최신 분류체계에 대하여 자세히 기록하였다. Three species of powdery mildew (Erysiphales) on eggplant (Solanum melongena L.) have been listed in Korea, namely Erysiphe cichoracearum (now genus Golovinomyces), Leveillula taurica, and Sphaerotheca fusca (now genus Podosphaera; syn. Podosphaera xanthii). Since E. cichoracearum was recorded on eggplant for the first time in Korea in 1969, it has been regarded as a major powdery mildew agent on that plant. In 1998, the causal agent of powdery mildew on eggplant was recorded as L. taurica, then as S. fusca in 2002. During our extensive field surveys in Korea, we collected 22 samples of eggplant powdery mildews. Our microscopic observations and molecular sequence analyses showed that all of our samples belonged to the genus Podosphaera, in the absence of either E. cichoracearum or L. taurica, suggesting that P. xanthii is the dominant agent of powdery mildew disease on eggplants in Korea. As there have been no additional findings on L. taurica after the first report on the species, it seems to be a minor species that is rarely found in greenhouses. The presence of E. cichoracearum (syn. Golovinomyces cichoracearum s. lat.) on eggplants is questionable, as the morphological characteristics of E. cichoracearum in the original description of the Korean collection deviate from the morphological variations of this species. In addition, no herbarium material of E. cichoracearum remains. Consequently, it seems that P. xanthii is the main species of powdery mildew on eggplants, whereas L. taurica occurs rarely on eggplants, in Korea. This review provides the historical and recent taxonomy of eggplant powdery mildews in detail.

Recently, environmental problems have emerged as a major issue all over the world due to an increase in carbon dioxide(CO<sub>2</sub>). The amount of CO<sub>2</sub> generated during cement production accounts for 6% to 8% of domestic CO<sub>2</sub> emissions and a solution to reduce CO<sub>2</sub> emissions the construction industry is trying to use mineral admixtures to reduce cement. Since digestion has no firing process the advantage of it is that there is no air pollution to occur. In this study, we studied the compressive strength of binary non-cement mortar containing rice husk powder extracted from digestion by the ratio of 10%, 20%, 30%, 40%. As a result, the table flow was increased when the mixing rate of rice husk powder extracted from digestion was higher, and the highest compressive strength was shown when the rice husk powder extracted from digestion mixing rate was 10%.

Background: Psychological interventions have potentials for improving disease management and quality of life in children with atopic dermatitis (AD) and their families. However, integration of medical and psychological health care in the treatment of children with AD is very rare in Korea. Objective: The aim of this study was to present descriptive data from a hospital-based interdisciplinary program that provides integrated medical and psychological health-care for children with AD. Method: Clinical records were reviewed for 127 children seen in our program as well as common problems and interventions addressed during family visits with the program psychologist. Age group differences in problems and interventions addressed during psychology sessions were evaluated. Also, the differences by symptom severity and sex in problems addressed during psychology sessions were analyzed. Result: Significant age-group differences were found in the problems and interventions addressed during psychology sessions. Among the age groups, sleep problems were most common in the <5 age group (50.0%). Negative self-image, problems of being bullied and attention problems were most common in the 6~12 age group (25.4%, 23.7% and 16.9%, respectively). Anxious/depressed mood, study burden and parent-child relational problems were most common in the 13~18 age group (65.0%, 60.0% and 45.0% respectively). Conclusion: The results of this study support the need for and feasibility of providing integrated care for children with AD and their families. Age-group differences found in problems and interventions addressed during psychology sessions could be useful especially in planning for group sessions.
