A leaf spot of cotton rose(Hibiscus mutabilis) occurred severely in the flower beds of cotton rose around Uiryeong-gun, Gyeongnam Province in Korea. The causal fungus was identified as Corynespora cassiicola on the basis of cultural and morphological characteristics of the fungus. The fungus grew well on potato dextrose agar and the colony color was gray to brown. Conidia were solitary or catenate, obclavate to cylindrical in shape, and pale olivaceous brown or brown in color. They had 420 pseudosepta, and measured $35.2{\sim}173.6{\times}8.8{\sim}19.9{\mu}m$. Conidia germinated as a bipolar type. Conidiophores were pale to mid brown in color, and measured $74.2{\sim}275.6{\times}3.8{\sim}10.8{\mu}m$. Optimal temperature for mycelial growth was $30^{\circ}C$. The fungal isolate grown on PDA showed strong pathogenicity to cotton rose plant. This is the first report on the corynespora leaf spot of cotton rose(Hibiscus mutabilis) caused by Corynespora cassiicola in Korea.

A destructive stem rot of tomato(Lycopersicon esculentum) occurred sporadically some farmers' fields in Jinju City, Gyeongnam province in Korea. The infected plants also showed stem, crown rot or whole plant blight. White mycelium spread over stems of infected plants and formed sclerotia on the old lesions nearby soil surface. The fungus showed maximum mycelial growth around $30^{\circ}C$. The fungus formed white colony on PDA, usually with many narrow mycelial strands in the aerial mycelium and the width were $4.0{\sim}9.8{\mu}m$. The typical clamp connections were formed on the mycelium. Numerous sclerotia was formed on PDA at $30^{\circ}C$. The shape of sclerotia was globoid and $1.0{\sim}3.0$ mm in size. The fungus was isolated repeatedly from the infected tissues and the pathogenicity was confirmed to tomato and identified as Sclerotium rolfsii. This is the first report on the stem rot of tomato caused by S. rolfsii in Korea.

The purpose of this study was to examine the maintenance of an evaluation accreditation indicator according to child care center teachers' participation in decision making. The subjects of this study were 139 teachers from 12 accredited national, public, private, and corporate child care centers in Seoul and North Gyeongsang Province. The TIP-2 (Teacher Involvement and Participation Scale V.2) and Accreditation Indicator for Child Care Centers were used to measure teachers' participation in decision making and accreditation indicator maintenance. Frequency, mean, standard deviation, one-way ANOVA and scheffe test were used for data analyses. The results revealed that the teachers who rated middle and high level in terms of their participation in decision-making showed higher levels of maintenance of the evaluation accreditation indicator than those with low levels of participation. This finding suggests that teachers' participation in decision making is an important factor for maintaining the quality of child care centers.

Dokdo, a group of 33 small and rocky Islets, in the East Sea have been administered by Korea for years since 1953 and are currently occupied by Korean Police Unit. Located about 217Km off the eastern border of Korea and 87Km east of UIleung Island in North Gyeongsang Province. Situated in the East Sea of Korea, Dokdo itself has valuable strategic implications for Korea as well as another countries such as Russia, Japan, U.SA etc. The first historical testimonies to Dokdo were in Korean documents referring to it as a part of an independent island district known as Ulleung Island(Usanguk), which was incorporated into Silla Kingdom in 512 A.D. in '1454 Sejong Authentic History'. Historically, since at least 1881, the island has been called Dokdo by Koreans, meaning 'Rock Island' or 'Lonely Island'. Also Korea, which regained a full sovereignty and have exercised it for decades continuously, keeps a small police detachment on the Island. That is, Dokdo is under effective control of Korea until today. Therefore Dokdo, which is a problem that is related to our territory and sovereignty, is clearly a cluster of Islands of Korea.

Fungal species belonging to the genus Penicillium are indigenous to a wide range of natural environments. Since the first published reports detailing the discovery of Penicillium, new species have been identified in various countries, including Korea. We present here a full characterization of five species of Penicillium that were previously unreported in Korea. Based on the morphologic characteristics and sequences of genes encoding fungal ��-tubulin and calmodulin, we identified five Penicillium species, including P. hetheringtonii, P. sublectaticum, and P. jacksonii, which have been unrecorded in Korea, and confirming P. maximae and P. cremeogriseum, as the endophytic fungi isolated in Gyeongsang province, Korea. In this article, we provide detailed morphological descriptions of these fungal species.

During the screening of Korean microflora, a fungal strain (KNU-PT-1804) belonging to the genus Pestalotiopsis was isolated from persimmon tree (Diospyros kaki) bark collected from North Gyeongsang Province, Korea. The strain, KNU-PT-1804, produced smaller conidia compared with related species P. kenyana, P. neglecta, and P. telopeae. The novelty of the strain was confirmed based on phylogenetic analysis using molecular datasets of internal transcribed spacer (ITS) regions, β-tubulin (TUB2), and translation elongation factor 1-alpha (TEF1α) genes. Molecular phylogeny strongly supports that the strain is distinct from previously known Pestalotiopsis species, and we proposed the novel species, Pestalotiopsis kaki sp. nov., and provide a detailed description and illustration.
